Veneer Peeling Machine

Improve Efficiency
The equipment produces high-quality, uniform panels ideal for plywood construction. These machines can adjust the thickness of the log based on its size and type and have better accuracy than manual rotary cutting. This uniformity ensures that the plywood produced is of consistent quality. Its consistency is essential to ensure that plywood is strong, durable and has excellent aesthetics.

Higher Accuracy
Automatic veneer rotary cutters produce high-quality, uniform veneers ideal for plywood construction. These machines can adjust the thickness of the veneer to the size and type of log and have better accuracy than manual rotary cutting. This uniformity ensures that the plywood produced is of consistent quality. Its consistency is critical to ensuring that plywood is strong, durable and has excellent aesthetics.

Consistency Of Production
Consistency is one of the essential characteristics of any manufacturing process. Using automatic veneer rotary cutting machines, manufacturers can ensure the consistency of the thickness, length and width of the veneer produced. Consistency makes it possible to produce plywood that meets strict industry standards. The machine ensures the consistency of the finished product, which is very important for construction projects and high-end furniture manufacturing.

Reduce The Risk Of Injury
Manually stripping veneer is a dangerous and tedious task with a high risk of injury. Workers stood near the spinning logs and had to push a sharp knife to peel off the boards. Improper use of knives can lead to accidents or result in substandard veneers. The use of automated equipment reduces the risk of injury and makes workers' jobs safer. Machine guards and safety measures minimize the risk of accidents, making operations safer and workers more comfortable.

Rotary Cutters: These machines employ a revolving knife to transform a wood or bamboo log into a slender veneer. Rotary cutting is particularly suited for softwoods and is capable of generating an array of grain patterns and textures.

Clipper Veneer Machines: Clipper veneer machines utilize guillotine blades to trim veneer sheets, favored for hardwoods to yield more consistent and neatly edged veneers.

Guillotine Veneer Cutters: These stationary machines vertically slice the material with a blade set, ideal for smaller-scale operations or bespoke cuts.

Half Round Slicer Veneer Machines: Half-round slicers produce semi-circular cross-section veneer sheets, apt for thinly slicing ornate or decorative logs.

Automatic Veneer Peeling Lines: These comprehensive systems incorporate multiple machines to swiftly peel an entire log, tailored for mass production and compatible with various wood types.

Rotary debarking has fast become a preferred method for multiple stem continuous feed wood debarking and processing for forest industries. Variants of this 20-year-old technology are being recognized as a viable alternative to single stem debarking methods used in some processes such as sawmills. The adjustable and positive nature of the debarking action coupled with a simple design produces the benefits of clean stems and low maintenance costs.

The term rotary debarking is commonly used to describe a log debarking device that uses a stationary bin where rotating shafts protrude along the bottom or sides. These shafts are fitted with a variety of tooling that provides controlled agitation of the wood fiber in the bin. As the shafts turn, the action of the tooling abrades the wood and creates cuts, fissures or weak points in the bark. Stem to stem contact rubs the bark from the wood, as does the continued action of the shafts and tooling. The logs circulate in the bin until the bark is adequately removed.

Debarking frozen wood can be extremely difficult - even non-existent in drum debarkers - without first preconditioning the log to lower the required direct mechanical or passive log-on-log energy input requirement. Rotary debarkers, however, are an improvement over traditional drum debarking. Rotary debarkers use tooling to increase abrasion. They also allow an increase in rotor speeds while bin loading is simultaneously increased. These factors all contribute to the increased energy required in more difficult debarking situations.

Effect Of Freezing On Debarking Effeciency

• Green aspen unfrozen requires 50#'s/square inch energy input.
• Green aspen at 0 degrees Celsius requires 115#'s/square inch.
• Green aspen at –5 degrees Celsius requires 280#'s/square inch.
• Green aspen at –65 degrees Celsius requires 480#'s/square inch.
• Appears that the energy input increase required to remove bark from frozen aspen flattens at –80 degrees Celsius.
• Similar though not identical effects can be seen in other species.

Rotary Debarker
The rotary debarking process is dry and no effluent treatment or water source is required. Occasionally, though, a minimal water spray is used to control dust. Footprints are shorter as no deicing or conditioning decks are required. Rotary debarking installations will see a savings in reduced maintenance costs when compared to a drum/deicing deck combination. With a history of straight line low maintenance costs compared to the exponential rise in operating costs for drums as they near the end of their useful life, rotary debarking makes a considerable and positive impact on return on investment calculations (ROI).

In addition, rotary debarkers are able to use more of the fiber that is otherwise left behind in the field. Where, historically, small diameter tops and rat tails have been left in the forest by topping at 75 to 100 mm, this fraction of the raw material source can now be delivered to the facility and the fiber effectively debarked (with no noticeable rise in debarking costs per unit). Long-term studies have indicated an ability to increase fiber utilization by 10 to 15% without harvesting any additional fiber when employing rotary debarkers and a well-designed forest harvesting practices format. This, again, can have a dramatic and positive impact on ROI calcula-tions.

Rotary Debarker Designs
There are two basic designs of rotary debarkers, one is the closed bottom (CB) and the other is the open bottom live floor (OBLF). While they share a number of characteristics, each is unique.
CB rotary debarking is the original improvement over drum debark-ing technology, while OBLF rotary debarking is an improvement on CB rotary debarking itself. OBLF rotary debarking has recently been incorporated into discharge batch (DB) stem management with increased benefits.
DB rotary debarking has the potential to have as large an impact on debarking technology as rotary debarking has had on drum debarking technology.

Capacity and Size: Gauge the log volume you plan to process and opt for a machine whose capacity aligns with your production needs without taxing the equipment.

Wood Species Compatibility: Verify that the machine is compatible with the wood species you intend to process. While some machines are tailored for specific woods like hardwoods or softwoods, others are versatile enough to handle a broader range.

Quality of Output: The intended use of your end product may necessitate a machine that consistently delivers high-quality veneer with minimal flaws.

Efficiency: Seek machines that boast high productivity rates, which can significantly enhance your manufacturing efficiency.

After-Sales Service: Dependable after-sales support, such as online technical assistance or field maintenance services, is vital for uninterrupted operation.
