Description

Technical Field

[0001] This invention relates to the technical field of wood veneer splicing and cutting equipment, specifically to a wood veneer splicing and cutting production line. Background Technology

[0002] Solid wood plywood is produced by hot-pressing multiple layers of stacked wood veneers. Rotary cutting of tree trunks or thick branches yields rotary-cut veneers, which are very thin. However, due to the rotary cutting process, the veneers are naturally curved, and their edges are not regular shapes due to the curvature or poor roundness of the trunk or branches. Some veneers may even have gaps or holes in the center. Therefore, the rotary-cut veneers need to be leveled first, and then trimmed to obtain rectangular veneers. If there are still defects or holes in the center of the veneer, the defective or holed parts need to be removed, dividing the veneer into multiple rectangular veneers. These veneers are then spliced ​​and fixed together to form a connected veneer. Finally, the continuous veneers are cut into relatively large sizes according to the dimensions of the subsequent hot-pressed solid wood plywood.

[0003] However, the production and processing equipment for the above processes is not located together. Different equipment needs to use transfer racks to move the wood panels between them. This not only requires additional personnel and equipment for this transfer, increasing production costs, but also inevitably results in some wood veneer loss during the transfer process, further increasing costs. Furthermore, the production volumes of different processes cannot be easily and intuitively coordinated, leading to backlogs in some processes and idle time in others, resulting in reduced production efficiency. Moreover, the relatively loose distribution of various production equipment also leads to wasted production space. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a wood veneer splicing and cutting production line, which facilitates centralized processing of wood veneer trimming, sorting, connecting strip processing, splicing and cutting, with compact equipment distribution, saving space, and realizing assembly line production of wood veneer splicing and cutting.

[0005] The technical solution adopted in this invention is:

[0006] A wood veneer splicing and cutting production line includes a wood veneer conveyor belt. A cutting machine is connected to the end of the conveyor belt, with the inlet of the cutting machine corresponding to the end of the conveyor belt. An outlet conveyor belt is connected to the outlet of the cutting machine, with its beginning corresponding to the outlet of the cutting machine. A wood veneer receiving rack is connected to the end of the outlet conveyor belt. Along the conveying direction of the wood veneer conveyor belt, a rotary cutting board loading conveyor belt and a connecting strip conveyor belt are sequentially arranged on one side of the wood veneer conveyor belt. The rotary cutting board loading conveyor belt... The conveying directions of the board feeding conveyor belt, the connecting strip conveyor belt, and the wood veneer conveyor belt are all the same. The board feeding conveyor belt and the wood veneer conveyor belt are connected in sequence along the conveying direction with a feeding station and a trimming station. The connecting strip conveyor belt and the wood veneer conveyor belt are connected with a board selection station and a connecting strip cutting station. The wood veneer conveyor belt is located on one side of the connecting strip conveyor belt and is connected at the end of the connecting strip conveyor belt with a wood veneer splicing station. The end of the discharge conveyor belt is located on one side of the wood veneer receiving rack with a discharge station.

[0007] A further improvement of the present invention is that multiple trimming stations are sequentially arranged along the conveying direction of the rotary cutting plate conveyor belt.

[0008] A further improvement of the present invention is that a trimming machine is provided at the trimming station.

[0009] A further improvement of the present invention is that the board selection station is provided with a wood veneer placement area for processing connecting strips, and the wood veneer placement area is located between the board selection station and the connecting strip conveyor belt.

[0010] A further improvement of the present invention is that the plate selection station is provided with two connecting strip cutting stations, one of which is located in front of the corresponding plate selection station along the conveying direction of the connecting strip conveyor belt, and the other is located in the rear of the corresponding plate selection station along the conveying direction of the connecting strip conveyor belt.

[0011] A further improvement of the present invention is that a strip cutting machine is provided at the connecting strip cutting station.

[0012] A further improvement of the present invention is that multiple wood veneer sorting stations are sequentially arranged between the connecting strip conveyor belt and the wood veneer conveyor belt, and on the rear side of the board selection station and the connecting strip cutting station along the conveying direction of the connecting strip conveyor belt.

[0013] A further improvement of the present invention is that a connecting strip collecting device is provided at the conveying end of the connecting strip conveyor belt. The connecting strip collecting device is set in a direction perpendicular to the conveying direction of the connecting strip conveyor belt, and one end of the connecting strip collecting device extends toward the wood veneer conveyor belt. The wood veneer splicing station is located on one side of the connecting strip collecting device. The wood veneer conveyor belt is located on one side of the wood veneer splicing station, and an adhesive applicator is provided at the position corresponding to the wood veneer splicing station.

[0014] A further improvement of the present invention is that the glue application device is located between the connecting strip collecting device and the wood veneer conveyor belt, and two wood veneer splicing stations are provided, respectively located on the front and rear sides of the connecting strip collecting device along the conveying direction of the wood veneer strip conveyor belt.

[0015] A further improvement of the present invention is that a wood veneer splicing inspection station is provided on one side of the wood veneer conveyor belt, located behind the wood veneer splicing station along the conveying direction of the wood veneer strip conveyor belt.

[0016] The beneficial effects of this invention are as follows:

[0017] First, the wood veneer splicing and cutting production line of the present invention facilitates centralized processing of wood veneer trimming, sorting, connecting strip processing, splicing and cutting. The equipment is compactly distributed, saving space, and realizing the assembly line production of wood veneer splicing and cutting.

[0018] Secondly, the wood veneer splicing and cutting production line of the present invention has multiple trimming stations, connecting strip cutting stations, wood veneer sorting stations, and wood veneer splicing stations, which can ensure that the conveying speed of each conveyor belt is adapted to the speed of each conveyor belt, thereby ensuring the splicing and cutting efficiency of the wood veneer. This allows for a reduction in the number of production lines while maintaining productivity, thereby reducing production costs.

[0019] Third, the wood veneer splicing and cutting production line of the present invention, by processing the narrower wood veneers after trimming into connecting strips, not only reduces the number of splices per unit length of continuous wood veneers, thus ensuring the uniformity of the thickness of the spliced ​​wood veneers as much as possible; it also ensures the consistency of the material between the connecting strips and the wood veneers themselves, thereby ensuring the consistency of the overall physical strength properties of the wood veneers and facilitating subsequent operations; in addition, there is no need to purchase additional connecting strips, reducing production costs and ensuring the utilization rate of wood.

Along the conveying direction of the wood veneer conveyor belt 2, a rotary-cut board loading conveyor belt 1 and a connecting strip conveyor belt 3 are sequentially arranged on one side of the wood veneer conveyor belt 2. The rotary-cut board loading... The conveyor belt 1, the connecting strip conveyor belt 3, and the wood veneer conveyor belt 2 all have the same conveying direction. The veneer feeding conveyor belt 1 and the wood veneer conveyor belt 2 are connected by a feeding station 12 and a trimming station 13 along the conveying direction. The connecting strip conveyor belt 3 and the wood veneer conveyor belt 2 are connected by a board selection station 14 and a connecting strip cutting station 15. The wood veneer conveyor belt 2 is located on one side of the connecting strip conveyor belt 3, and a wood veneer splicing station 17 is also provided at the end of the connecting strip conveyor belt 3. The discharge conveyor belt 5 is located at the end of the conveying belt, and a discharge station 19 is also provided on one side of the wood veneer receiving rack 6.

[0022] The trimming stations 13 are arranged in multiple ways along the conveying direction of the rotary cutting plate conveyor belt 1.

[0023] The trimming station 13 is equipped with a trimming machine.

[0024] The board selection station 14 is provided with a wood veneer placement area 8 for processing connecting strips. The wood veneer placement area 8 is located between the board selection station 14 and the connecting strip conveyor belt 3.

[0025] The plate selection station 14 is provided with two connecting strip cutting stations 15. One connecting strip cutting station 15 is located in front of the corresponding plate selection station 14 along the conveying direction of the connecting strip conveyor belt 3, and the other connecting strip cutting station 15 is located behind the corresponding plate selection station 14 along the conveying direction of the connecting strip conveyor belt 3.

[0026] The connecting strip cutting station 15 is equipped with a strip cutting machine 9.

[0027] Multiple wood veneer sorting stations 16 are sequentially arranged between the connecting strip conveyor belt 3 and the wood veneer conveyor belt 2, located at the board selection station 14 and the connecting strip cutting station 15, along the rear side of the conveying direction of the connecting strip conveyor belt 3.

[0028] The connecting strip conveyor belt 3 is provided with a connecting strip collecting device 10 at its conveying end. The connecting strip collecting device 10 is set in a direction perpendicular to the conveying direction of the connecting strip conveyor belt 3, and one end of the connecting strip collecting device 10 extends toward the wood veneer conveyor belt 2. The wood veneer splicing station 17 is located on one side of the connecting strip collecting device 10. The wood veneer conveyor belt 2 is located on one side of the wood veneer splicing station 17, and an adhesive applicator 11 is provided at the position corresponding to the wood veneer splicing station 17.

[0029] The glue application device 11 is located between the connecting strip collecting device 10 and the wood veneer conveyor belt 2. There are two wood veneer splicing stations, which are respectively located on the front and rear sides of the connecting strip collecting device 10 along the conveying direction of the wood veneer strip conveyor belt 2.

[0030] On one side of the wood veneer conveyor belt 2, and on the rear side of the wood veneer splicing station 17 along the conveying direction of the wood veneer strip conveyor belt 2, there is also a wood veneer splicing inspection station 18.

[0031] During operation, the worker at the loading station 12 sequentially loads the processed and leveled veneer sheets onto the veneer loading conveyor belt 1 for conveying. The worker at the trimming station 13 removes the veneer sheets from the conveyor belt 1 and trims them using the trimming machine 7, removing any damaged or incomplete parts from the edges of the veneer sheets, leaving rectangular wood veneers. The edges A of one group of rectangular wood veneers are aligned with the wood grain direction, while the edges B of the other group are perpendicular to edge A, and the dimensions of edge A of the rectangular wood veneers are consistent. The rectangular wood veneers are then placed onto the wood veneer conveyor belt 2 for conveying. The worker at the board selection station 14 selects the wood veneer from the conveyor belt... 2. Wood veneers with smaller edge dimensions (less than 40 cm) from the conveyed wood veneers are removed and placed in the wood veneer placement area 8. The workers at the connecting strip cutting station 15 then use a strip cutting machine 9 to cut the wood veneers in the placement area 8 along a direction parallel to edge A, cutting them into several connecting strips. The length edge of the connecting strip is the edge A of the wood veneer, and the width of the connecting strip is in the range of 3-5 cm. The workers at the connecting strip cutting station 15 place the cut connecting strips onto the connecting strip conveyor belt 3 for conveying. The connecting strips are conveyed to the connecting strip collection device 10 via the connecting strip conveyor belt 3. When the wood veneer conveyor belt 2 conveys the wood veneers to the wood veneer sorting station 16, the workers at the wood veneer sorting station 16... The workers arrange the wood veneers conveyed on the wood veneer conveyor belt 2 to ensure that the edges A of each wood veneer are perpendicular to the conveying direction of the wood veneer conveyor belt 2, the opposing edges A of two adjacent wood veneers are close together, and the edges B of each wood veneer are flush. The workers at the wood veneer splicing station 17 remove the connecting strips from the connecting strip collection device 10 and apply glue to one end of the connecting strip using the glue application device 11. When the opposing edges A of two adjacent wood veneers on the wood veneer conveyor belt 2 pass through the wood veneer splicing station 17, the workers at the wood veneer splicing station 17 glue and fix the connecting strips to the opposing edges A of the two adjacent wood veneers, ensuring that both ends of the connecting strips fixed to the wood veneers are aligned with the edges B of the glued wood veneers. When the wood veneer conveyor belt 2 conveys the wood veneers that are fixed together by connecting strips to the wood veneer splicing inspection station 18, the staff at the wood veneer splicing inspection station 18 check the bonding effect of the wood veneers and connecting strips that are about to enter the cutting machine 4, ensuring that the connecting strips are tightly attached to the wood veneers and that both ends of the connecting strips are flush with the edge B of the wood veneers. The wood veneers that are connected as one piece are conveyed by the wood veneer conveyor belt 2 to the cutting machine 4 and then to the discharge conveyor belt 5. When the distance that the end of the wood veneer has been conveyed by the cutting machine 4 is the distance that the wood veneer needs to be cut, both the wood veneer conveyor belt 2 and the discharge conveyor belt 5 stop conveying at the same time, and continue conveying after the cutting machine 4 has finished cutting the wood veneer.The wood veneers cut by the cutting machine 4 are conveyed to the wood veneer receiving rack 6 via the discharge conveyor belt 5. The workers at the discharge station 19 then place the cut wood veneers conveyed by the discharge conveyor belt 5 into the wood veneer receiving rack 6.
