Description

Technical Field

[0001] This utility model relates to the technical field of wood processing, and in particular to a veneer cutting and cleaning device. Background Technology

[0002] Currently, multi-layered synthetic wood products can be made using wood veneer as the veneer through processes such as splicing and gluing. However, because wood veneer veneers are relatively narrow, to process them into larger wood-based panels, adhesives are needed to join two or more veneers together to form a larger panel. Specifically, there are two main types of splicing joints for wood veneer: straight joints and serrated joints. Straight joints require applying glue to the entire joint, resulting in high glue consumption, which is neither economical nor environmentally friendly, and the joints are prone to breakage under external force. Serrated joints, on the other hand, effectively increase the connection strength between two veneers, and applying glue only at the tips or roots of the serrations significantly reduces glue consumption. Existing veneer cutting equipment often uses a serrated blade to punch and create serrated joints. However, during the veneer cutting process, a significant amount of excess material is cut off, and the accumulation of this excess material can affect the subsequent cutting results. Currently, manual cleaning of leftover materials is the most common method, but this method is slow and can increase the workload for workers. Utility Model Content

[0003] To address the above shortcomings, this utility model proposes a single-board cutting and cleaning device. The device uses a support plate to support the leftover material from the single-board cutting and a first driving mechanism to drive the support plate away from the saw tooth groove, so that the scraper pushes the leftover material into the collection port, thereby facilitating the automatic cleaning of the leftover material.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A veneer cutting and cleaning device includes: a workbench with a serrated groove, a collection port at the bottom of the serrated groove, the collection port being connected to a collection pipe; a scraper located inside the serrated groove on the workbench; a support plate between the scraper and the bottom of the serrated groove; and a first drive mechanism connected to the support plate to drive it to move horizontally reciprocatingly; and a serrated cutting plate disposed on the workbench, connected to a second drive mechanism, the second drive mechanism being used to drive the serrated cutting plate to move vertically, so that the serrated cutting plate and the serrated groove cooperate to cut serrated edges from the veneer.

[0006] Furthermore, the sawtooth groove includes two opposing side plates, each side plate having a mounting groove, one mounting groove having a lead screw rotatably mounted thereon, and the other mounting groove having a guide rod mounted thereon. The lead screw and the guide rod are arranged parallel to each other in the vertical direction, and both the lead screw and the guide rod are fitted with mounting blocks. The scraper is located between the two mounting blocks, and the lead screw is used to drive one of the mounting blocks to move in the vertical direction.

[0007] Furthermore, one of the mounting blocks has a stepped groove on its upper part, and a limit block is provided at the lower end of the lead screw. The limit block is rotatably disposed in the stepped groove.

[0008] Furthermore, the scraping component includes a scraper, which is fixedly disposed between the two mounting blocks. The lower end face of the scraper is connected to bristles, which abut against the support plate.

[0009] Furthermore, the longitudinal cross-section of the serrated cutting plate gradually increases or decreases from one end to the other.

[0010] Furthermore, the second driving mechanism is a first cylinder mounted on the worktable, the telescopic end of the first cylinder is connected to a mounting plate, and a connecting rod is connected between the mounting plate and the support plate.

[0011] Furthermore, it also includes four support rods, which are rectangularly distributed on the lower end face of the worktable. An installation rod is provided between two opposing support rods, and the installation rod is located below the serrated groove. The first cylinder is disposed on the installation rod.

[0012] Furthermore, the collecting tube includes a flow guiding cavity, the flow guiding cavity having a flow guiding surface at one end connected to the side wall of the collecting port, the other end of the flow guiding surface being inclined away from the sawtooth groove, and a collecting box being provided at the lower end of the collecting tube.

[0013] Furthermore, the workbench includes two opposing side rods, with a crossbar connecting the two side rods. The first driving mechanism is a second cylinder disposed on the crossbar, and the telescopic end of the second cylinder is connected to the sawtooth cutting plate.

[0014] Compared with existing technologies, this utility model has at least the following beneficial effects:

[0015] 1. In this utility model, the second driving mechanism drives the support plate downward into the sawtooth groove, which not only cuts the sawtooth edge of the veneer, but also allows the cutting residue to fall onto the support plate.

[0016] 2. This utility model uses a first driving mechanism to drive the support plate away from the sawtooth groove, so that the scraper pushes the residual material into the collection port, thereby facilitating the automatic cleaning of residual material. Attached Figure Description

[0026] See Figures 1 to 3 A veneer cutting and cleaning device includes: a workbench 100, the workbench 100 being provided with a serrated groove 110, a collection port being provided at the bottom of the serrated groove 110, the collection port being connected to a collection pipe 120, the workbench 100 being provided with a scraper 130 located inside the serrated groove 110, a support plate 140 being provided between the scraper 130 and the bottom of the serrated groove 110, the support plate 140 being connected to a first drive mechanism that drives it to move horizontally back and forth; a serrated cutting plate 200 being provided on the workbench 100, the serrated cutting plate 200 being connected to a second drive mechanism, the second drive mechanism being used to drive the serrated cutting plate 200 to move in a vertical direction, so that the serrated cutting plate 200 and the serrated groove 110 cooperate to cut out the serrated edge of the veneer.

[0027] In the above-described veneer cutting and cleaning device, during use, the first drive mechanism drives the support plate 140 to move into the sawtooth groove 110, so that the support plate 140 blocks the collection port. Then, the second drive mechanism drives the sawtooth cutting plate 200 to cut the veneer downwards, so that the leftover material from the veneer falls onto the support plate 140, thereby using the support plate 140 to support the leftover material from the veneer. Finally, the first drive mechanism drives the support plate 140 away from the sawtooth groove 110, so that the scraper 130 can push the leftover material into the collection port, thereby facilitating the automatic cleaning of leftover material and reducing the workload of manual cleaning.

[0028] See Figures 1 to 3Furthermore, the serrated groove 110 includes two opposing side plates 111, each side plate 111 having a mounting groove 112. One mounting groove 112 is rotatably equipped with a lead screw 113, and the other mounting groove 112 is equipped with a guide rod 114. The lead screw 113 and the guide rod 114 are arranged parallel to each other in the vertical direction. Both the lead screw 113 and the guide rod 114 are fitted with mounting blocks 115. The scraper 130 is located between the two mounting blocks 115. The lead screw 113 is used to drive one of the mounting blocks 115 to move in the vertical direction, thereby adjusting the height position of one of the mounting blocks 115 through the lead screw 113. This facilitates changing the installation position of the scraper 130, making it easier for the scraper 130 to better scrape off the excess material on the support plate 140. It is understood that a flat plate 118 is provided at the upper end of the mounting groove 112, thereby using the flat plate 118 to provide the installation position for the lead screw 113 and the guide rod 114.

[0029] See Figures 1 to 3 Furthermore, one of the mounting blocks 115 has a stepped groove 116 on its upper part, and a limiting block 117 is provided at the lower end of the lead screw 113. The limiting block 117 is rotatably disposed in the stepped groove 116. Specifically, rotating the lead screw 113 causes the limiting block 117 to drive the mounting block 115 to reciprocate in the vertical direction, thereby changing the position of the scraper 130 relative to the side plate 111 in the vertical direction. It can be understood that the lead screw 113 is threadedly engaged with one of the mounting blocks 115, allowing the mounting block 115 to move along the length of the lead screw 113 under the action of the thread.

[0030] See Figures 1 to 3 Furthermore, the scraper 130 includes a scraper 131, which is fixedly disposed between two mounting blocks 115. The lower end face of the scraper 131 is connected to a bristle 132, which abuts against the support plate 140. The bristle 132 is used to clean the residual material on the support plate 140, which helps to improve the cleaning effect of residual material.

[0031] Furthermore, the longitudinal section of the serrated cutting plate 200 gradually increases or decreases from one end to the other, causing the lower end face of the serrated cutting plate 200 to form a first inclined surface. This results in a time difference between the contact between the serrated cutting plate 200 and the veneer at different positions along its length, thus creating a structure similar to the principle of scissors cutting between the serrated cutting plate 200 and the veneer. This increases the shearing force of the serrated cutting plate 200 on the veneer, making the serrated interface of the veneer cut smooth and flat. In some embodiments, the support plate 140 has a second inclined surface that matches the first inclined surface, allowing the serrated cutting plate 200 to form surface contact with the support plate 140. The use of bristles 132 also helps to better match the non-planar shape of the upper end face of the support plate 140.

[0032] See Figure 1and Figure 3 Furthermore, the second driving mechanism is a first cylinder 300 located on the workbench 100. The telescopic end of the first cylinder 300 is connected to a mounting plate 310. A connecting rod 311 is connected between the mounting plate 310 and the support plate 140. Thus, the first cylinder 300 drives the mounting plate 310 to move, causing the connecting rod 311 to move the support plate 140 into or away from the serrated groove 110.

[0033] See Figure 1 and Figure 3 Furthermore, it also includes four support rods 101, which are rectangularly distributed on the lower end face of the worktable 100. A mounting rod 102 is provided between two opposing support rods 101. The mounting rod 102 is located below the serrated groove 110. The first cylinder 300 is provided on the mounting rod 102, thereby providing a position for the first cylinder 300 to be installed.

[0034] See Figure 1 and Figure 3 Furthermore, the collection pipe 120 includes a guide cavity 121, which has a guide surface connected to the side wall of the collection port at one end, and the other end of the guide surface is inclined away from the sawtooth groove 110. A collection box 122 is provided at the lower end of the collection pipe 120, thereby using the guide surface to guide the residual material into the collection box 122, which improves the efficiency of residual material collection.

[0035] See Figure 1 and Figure 3 Furthermore, the workbench 100 includes two opposing side rods 103, with a crossbar 104 connecting the two side rods 103. The first driving mechanism is a second cylinder 150 disposed on the crossbar 104. The telescopic end of the second cylinder 150 is connected to the serrated cutting plate 200, thereby using the second cylinder 150 to drive the serrated cutting plate 200 to cut the veneer downwards. In some embodiments, the first cylinder 300 and the second cylinder 150 are bidirectional cylinders. The first cylinder 300 is connected to the air supply mechanism through a first pipeline, and the second cylinder 150 is connected to the air supply mechanism through a second pipeline. Both the first pipeline and the second pipeline are provided with switching valves for changing the air supply direction. The switching valves are electrically connected to a controller, thereby facilitating the controller to change the working state of the two switching valves, causing the serrated cutting plate 200 to move upwards and the support plate 140 to move away from the serrated groove 110. This is beneficial for timely cleaning of the leftover material after each veneer cutting, so as to avoid the accumulation of leftover material on the support plate 140.

[0036] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0037] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
