Description

Technical Field

[0001] This utility model belongs to the technical field of plywood production equipment, and more specifically, it relates to a plywood conveying equipment for plywood production. Background Technology

[0002] The main production processes for plywood include log processing (cutting and steaming), rotary veneer cutting, drying, gluing, assembly, hot pressing, cooling, edge trimming and sanding to remove burrs, and finally, after passing inspection, stacking and packaging. In the plywood production line, conveyor equipment is indispensable between these two processes. This equipment enables automated transfer of the boards, thereby saving labor costs, reducing worker workload, and improving production efficiency.

[0003] For example, the patent with announcement number "CN221395437U" discloses a sheet material conveyor that uses a pusher assembly to position the sheet material, ensuring the accuracy and safety of the sheet material conveying. A pressure roller assembly is set at the exit end to apply pressure to the sheet material, forcibly conveying it into the next process, preventing the sheet material from slipping at the exit end, thereby improving the efficiency of sheet material conveying.

[0004] While the aforementioned sheet conveyor solves the problems of sheet conveying and efficiency, its conveying process mainly relies on the friction between the conveyor rollers located at the bottom of the sheet and the bottom of the sheet. This conveying method is unsuitable for conveying veneers coated on both sides, nor for conveying sanded sheets. If plywood is conveyed in this way, the conveyor rollers will scratch the glued surface and the sanded surface, affecting the quality of the assembled sheets and the plywood. Furthermore, the pusher assembly in the aforementioned conveyor cannot be used for positioning and conveying coated sheets of different widths. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a board conveying equipment for plywood production. Its versatility makes it suitable for the automatic conveying of glued boards and sanded plywood of various widths and specifications, and avoids scratches on the glue surface and board surface, thus greatly improving product quality and conveying efficiency.

[0006] The aforementioned plywood production board conveying equipment includes a frame, with support legs fixedly connected to the bottom of the frame, a support beam fixedly connected to one side of the frame, sliding mechanisms installed at both ends and the middle of the frame, and a sliding plate shared by the three sliding mechanisms. The upper surface of the support beam is flush with the upper surface of the sliding plate, and multiple sets of telescopic transmission rods with equal spacing are rotatably connected between the support beam and the sliding plate. Anti-slip conical rollers for board transmission are fixedly connected to both ends of the telescopic transmission rods, and the transmission direction of the anti-slip conical rollers is perpendicular to the sliding direction of the sliding mechanism.

[0007] Preferably, a motor is fixedly connected to the side of the support beam away from the sliding plate, the output end of the motor passes through the support beam, and a driving wheel is fixedly connected to the end of the motor output end. A driven wheel one and a driven wheel two are fixedly connected to each telescopic transmission rod. Adjacent telescopic transmission rods are connected by transmission through the corresponding driven wheel one or driven wheel two. The driven wheel two on the telescopic transmission rod closest to the motor is connected to the driving wheel.

[0008] Preferably, the telescopic transmission rod includes a telescopic rod and a sleeve. The longitudinal section of the telescopic rod is quadrilateral or polygonal. A sliding hole that cooperates with the telescopic rod is opened in the middle of one end of the sleeve. One end of the telescopic rod is slidably disposed in the sliding hole. The ends of the telescopic rod and the sleeve that are far apart are respectively fixedly connected to a first transmission shaft and a second transmission shaft. Anti-slip conical rollers are respectively fixedly disposed at the ends of the first transmission shaft and the second transmission shaft.

[0009] Preferably, bearing seats are fixedly connected to the support beam and the sliding plate respectively, and the first transmission shaft is rotatably connected to the bearing seat on the support beam, and the second transmission shaft is rotatably connected to the bearing seat on the support beam.

[0010] Preferably, the driven wheel one and driven wheel two are mounted on the drive shaft one by a key.

[0011] Preferably, a limiting ring is fixedly connected to one end of the drive shaft near the telescopic rod, and the outer diameter of the limiting ring is larger than that of the sliding hole.

[0012] Preferably, the sliding mechanism includes a sliding rail and a slider that are slidably connected. The sliding rail is fixedly connected to the frame, a sliding plate is fixedly installed on the top of the slider, and a limit plate is fixedly connected to the end of the sliding rail away from the support beam.

[0013] Preferably, at least one telescopic cylinder is fixedly connected to the bottom of the frame, and a connecting plate corresponding to the telescopic cylinder is fixedly connected to the bottom of the sliding plate, with the extended end of the telescopic cylinder being movably connected to the connecting plate.

[0014] Preferably, the outer side of the anti-slip conical roller is provided with a rubber anti-slip layer, and the outer surface of the rubber anti-slip layer is provided with anti-slip texture.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. This utility model achieves automatic conveying of sheet metal by cooperating with a telescopic transmission rod and an anti-slip conical roller. By adjusting the cooperation between the telescopic rod and the rod sleeve, the length of the telescopic transmission rod can be adjusted, thereby adjusting the distance between the anti-slip conical rollers at both ends of the telescopic transmission rod, making it suitable for conveying sheet metal of various widths and greatly improving its versatility.

[0017] 2. During the conveying process, only the bottom edges of the two sides of the board are in contact with the anti-slip conical roller, and the board surface is suspended in the air, which avoids the possibility of scratching the board surface. The board is conveyed forward as the telescopic transmission rod rotates, and the conical surface of the anti-slip conical roller is inclined upward, which can limit the two sides of the board. During the conveying process, it can effectively prevent the board from deviating and greatly improve the stability of the board conveying.

[0018] 3. The anti-slip conical roller has a frustum structure. The end with the smaller diameter is fixedly connected to the telescopic transmission rod. The outer side of the anti-slip conical roller is provided with a rubber anti-slip layer. The outer surface of the rubber anti-slip layer is provided with anti-slip texture. The anti-slip texture can effectively increase the friction between the roller and the edge of the board, ensuring that the board will not slip during the conveying process, thus improving the accuracy and stability of the conveying.

[0028] The present invention will be further described below with reference to the accompanying drawings:

[0029] The directional terms used in the detailed description paragraphs are only for the convenience of those skilled in the art to understand the technical solutions described in this application based on the visual orientation shown in the accompanying drawings. Unless otherwise expressly specified and limited, the terms "setting," "installation," "connection," etc., should be interpreted broadly, and those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0030] like Figures 1 to 8 As shown, a plywood conveying device for plywood production includes a frame 1, which serves as the basic framework of the device and provides primary support. Support legs 101 are fixedly connected to the four corners at the bottom and both sides of the middle of the frame 1 to ensure that the device does not shake or shift during the conveying of plywood. A support beam 102 is fixedly connected to one side of the frame 1. The support beam 102 serves two purposes: firstly, to enhance the structural strength of the frame 1, and secondly, to install a telescopic transmission rod 5, which acts as a limit. Sliding mechanisms 2 are installed at both ends and the middle of the frame 1. A sliding plate 3 is mounted on each of the three sliding mechanisms 2. The sliding plate 3 is parallel to the support beam 102. The three sliding mechanisms 2 work together to support the same sliding plate 3, resulting in more even force distribution and smoother sliding. The upper surface of the support beam 102 is flush with the upper surface of the sliding plate 3. Multiple sets of equally spaced telescopic transmission rods 5 are rotatably connected between the support beam 102 and the sliding plate 3. The length direction of the telescopic transmission rods 5 is perpendicular to the length direction of the support beam 102 and the sliding plate 3. Anti-slip conical rollers 7 for transmitting the material 9 are fixedly connected to both ends of the telescopic transmission rods 5. The transmission direction of the anti-slip conical rollers 7 is perpendicular to the sliding direction of the sliding mechanisms 2. The flush alignment of the support beam 102 with the upper surface of the sliding plate 3 ensures that both ends of the telescopic transmission rods 5 and the anti-slip conical rollers 7 are at the same height, preventing the material 9 from tilting during transport. The conical structure of the anti-slip conical rollers 7 limits the movement of the material 9 at both ends, preventing it from deviating.

[0031] like Figure 1 and Figure 4As shown, a motor 8 is fixedly connected to the side of the support beam 102 away from the sliding plate 3. The motor 8 serves as the power source for the entire conveying equipment, driving the telescopic transmission rods 5 to rotate. Its output end passes through the support beam 102, and a drive wheel 801 is fixedly connected to the end of the motor 8 located inside the support beam 102. Each telescopic transmission rod 5 is fixedly connected to a driven wheel 601 and a driven wheel 602. In this embodiment, the drive wheel 801, driven wheel 601, and driven wheel 602 are preferably sprockets. Adjacent telescopic transmission rods 5 are connected by chain drive through the corresponding driven wheel 601 or driven wheel 602. The driven wheel 602 on the telescopic transmission rod 5 closest to the motor 8 is connected to the drive wheel 801 by chain drive. The above structure enables the power of the motor 8 to be transmitted sequentially to each telescopic transmission rod 5 through the above transmission method, thereby driving all telescopic transmission rods 5 to drive synchronously and ensuring the stability of the conveying of the plate 9.

[0032] like Figure 5 and Figure 6 As shown, the telescopic transmission rod 5 includes a telescopic rod 501 and a sleeve 504. The longitudinal section of the telescopic rod 501 is quadrilateral or polygonal. In this embodiment, the telescopic rod 501 is preferably a hexagonal shaft. A sliding hole 5041 that mates with the telescopic rod 501 is provided in the middle of one end of the sleeve 504. One end of the telescopic rod 501 is slidably disposed in the sliding hole 5041. This non-circular cross-section mating design effectively prevents relative rotation of the telescopic rod 501 within the sleeve 504, ensuring the stability of power transmission. A transmission shaft 1 502 is fixedly connected to the other end of the telescopic rod 501. A transmission shaft 2 505 is fixedly connected to the end of the sleeve 504 away from the telescopic rod 501. The cross-sections of the transmission shaft 1 502 and the transmission shaft 2 505 are circular. Anti-slip conical rollers 7 are respectively fixedly disposed at the ends of the transmission shaft 1 502 and the transmission shaft 2 505. By adjusting the fit between the telescopic rod 501 and the sleeve 504, the length of the telescopic transmission rod 5 can be adjusted, thereby adjusting the distance between the anti-slip conical rollers 7 at both ends of the telescopic transmission rod 5, making it suitable for conveying plates 9 of various widths and greatly improving its versatility.

[0033] like Figure 2 and Figure 3 As shown, bearing seats 603 are fixedly connected to the support beam 102 and the sliding plate 3, respectively. Drive shaft one 502 is rotatably connected to the bearing seat 603 on the support beam 102, and drive shaft two 505 is also rotatably connected to the bearing seat 603 on the support beam 102. The bearing seats 603 reduce the frictional force when the telescopic transmission rod 5 rotates, thus improving transmission efficiency. Driven wheel one 601 and driven wheel two 602 are fixedly mounted on drive shaft one 502 by keys, ensuring a tight fit between the driven wheels and the drive shaft and preventing slippage.

[0034] In this embodiment, a limiting ring 503 is fixedly connected to one end of the drive shaft 502 near the telescopic rod 501. The outer diameter of the limiting ring 503 is larger than that of the sliding hole 5041. The limiting ring 503 plays a limiting role when the telescopic drive rod 5 retracts, preventing the rod sleeve 504 from entering the drive shaft 502 and damaging the driven wheel 601 and the driven wheel 602.

[0035] The sliding mechanism 2 includes a sliding rail 201 and a slider 202 that are slidably connected. The sliding rail 201 is fixedly connected to the frame 1, providing a stable sliding track for the slider 202. A sliding plate 3 is fixedly installed on the top of the slider 202, and the sliding plate 3 can move as the slider 202 slides on the sliding rail 201. A limit plate 203 is fixedly connected to the end of the sliding rail 201 away from the support beam 102. The limit plate 203 prevents the slider 202 from slipping off the sliding rail 201, ensuring the safe operation of the sliding mechanism 2. On the other hand, it prevents the telescopic rod 501 from coming out of the rod sleeve 504, ensuring the normal operation of the telescopic transmission rod 5.

[0036] Two telescopic cylinders 4 are fixedly connected to the bottom of the frame 1. A connecting plate 301 corresponding to the two telescopic cylinders 4 is fixedly connected to the bottom of the sliding plate 3. The extended end of the telescopic cylinder 4 is movably connected to the connecting plate 301. By controlling the extension and retraction of the telescopic cylinders 4, the position of the sliding plate 3 can be flexibly adjusted to adapt to the conveying needs of plates of different thicknesses.

[0037] The anti-slip conical roller 7 has a frustum structure, with its smaller diameter end fixedly connected to the telescopic transmission rod 5. To further improve the transmission stability of the sheet metal 9, a rubber anti-slip layer is provided on the outer side of the anti-slip roller 7, and the outer surface of the rubber anti-slip layer has anti-slip textures. The anti-slip textures effectively increase the friction between the roller and the edge of the sheet metal 9, ensuring that the sheet metal 9 does not slip during conveying, thus improving the accuracy and stability of the conveying process.

[0038] like Figure 8As shown, in use, the board 9 can be a veneer with double-sided adhesive, or it can be a pre-assembled or cut plywood. During operation, the spacing between the two corresponding anti-slip conical rollers 7 is adjusted according to the width of the board 9. The adjustment process is as follows: The telescopic cylinder 4 is activated, and the telescopic cylinder 4 retracts, which can pull the sliding plate 3 along the slide rail 201 to the side of the support beam 102. During the movement, the telescopic rod 501 retracts into the sleeve 504, and the telescopic rod 501 and the sleeve 504 are polygonal structures, so there will be no relative rotation. After the spacing is adjusted, start the motor 8. The motor 8 drives the adjacent telescopic transmission rod 5 to rotate through the drive wheel 801 and the driven wheel 602. The other telescopic transmission rods 5 rotate in sequence through the cooperating driven wheel 601 or driven wheel 602, placing the plate 9 on the corresponding anti-slip conical roller 7. At this time, only the bottom of the two sides of the plate 9 are in contact with the anti-slip conical roller 7, and its surface is suspended, avoiding the possibility of scratching the plate surface. The plate 9 is conveyed forward as the telescopic transmission rod 5 rotates. The conical surface of the anti-slip conical roller 7 is inclined upward, which can limit the two sides of the plate 9. During the conveying process, it can effectively prevent the plate from deviating and greatly improve the stability of the plate 9 conveying.

[0039] Finally, although this specification describes embodiments, not every embodiment contains only one independent technical solution. This way of describing the specification is only for clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
