Description

Technical Field

[0001] This utility model relates to the field of plywood processing technology, specifically to a chamfering device that facilitates plywood processing. Background Technology

[0002] Plywood, a core material widely used in furniture manufacturing and the production and processing of various wooden clamps, has a sophisticated and complex manufacturing process. It originates from the fine rotary cutting of wood segments or the precise planing of wood squares. These thin wood veneers are then bonded layer by layer using efficient adhesive technology to form a stable and well-defined three- or even multi-layer board. In the practical application of plywood, the treatment of edges and corners is particularly important to improve its aesthetics and safety. At this time, it is necessary to use professional beveling equipment to perform fine beveling on the edges and corners of the plywood, making the edges rounded and smooth. This not only enhances the comfort of use but also gives the product a more elegant and harmonious appearance.

[0003] According to publicly available patent CN222386602U, a chamfering device for facilitating plywood processing includes a frame and a mounting base, with the mounting base located at the top of the frame. When using this chamfering device, the handle on the right side of the mounting base is rotated according to the width of the plywood, driving a double-acting screw. Simultaneously, the rotation of the double-acting screw, using the first threaded sleeve connected to the external threads on both sides, drives the connecting plate, support, and fixed base to move inwards at the top of the mounting base. After adjusting the positions of the two sets of mounting frames and grinding heads to fit the two ends of the top of the plywood, the two sets of grinding heads can be used to chamfer the two sides of the top of the plywood. The first threaded sleeve and double-acting screw allow for quick adjustment and chamfering of plywood of different widths, solving the problem of inconvenience in quickly adjusting the chamfering of plywood of different widths. In the process of developing this utility model, the inventors discovered that at least the following problems remain unresolved in the existing technology. While the problem of not being able to chamfer plywood of different widths is solved by setting a chamfering mechanism that can move horizontally or relatively, in actual use, as the conveyor roller rotates and moves the plywood horizontally while its side edges are being ground and chamfered, the grinding head, upon contacting the plywood surface, provides a corresponding reverse pushing force to the plywood as the grinding head rotates. Furthermore, since there is no corresponding limiting structure for the plywood on the conveyor belt surface, the plywood is prone to shifting backward on the conveyor roller surface during chamfering, resulting in the grinding head being unable to fully chamfer the edges of the plywood. Therefore, a new technical solution is needed to address these issues. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology, adapt to practical needs, and provide a chamfering device that facilitates plywood processing. This addresses the current technical problem where, while the plywood is being moved horizontally by the rotating conveyor rollers, its side edges are being ground and chamfered. The grinding head, upon contacting the plywood surface, provides a corresponding reverse pushing force to the plywood as it rotates. Furthermore, since there is no corresponding limiting structure for the plywood on the conveyor belt surface, the plywood is easily moved backward on the conveyor roller surface during chamfering, resulting in the grinding head being unable to adequately chamfer the plywood edges.

[0005] To achieve the purpose of this utility model, the technical solution adopted by this utility model is as follows: a chamfering device for easy plywood processing is designed, including a processing table, on both sides of the top of the processing table a first electric slide rail is fixedly installed, a mounting frame is connected between the tops of the first electric slide rails, a second electric slide rail is movably installed on the top of the inner side of the mounting frame, and sliding plates are slidably installed on both sides of the bottom of the second electric slide rail.

[0006] The processing table has a rotating groove in the middle, and a bearing plate is rotatably installed inside the rotating groove. The bearing plate is hollow inside, and a vent hole is opened at the top of the bearing plate. A sealing plunger is movably inserted into the vent hole. A vacuum pumping mechanism is provided at the bottom of the processing table, and the vacuum pumping mechanism is connected to the inside of the bearing plate.

[0007] A transmission frame is fixedly installed on the other side of the bottom of the processing table, and a rotating mechanism is provided inside the transmission frame, which is connected to the bearing plate in a transmission manner.

[0008] Preferably, the vacuum pumping mechanism includes a vacuum pump, which is fixedly installed on the bottom side of the processing table. A connecting bend is fixedly connected to the side of the vacuum pump, and an extraction pipe is vertically fixedly connected to the middle of the bottom of the support plate. The extraction pipe is rotatably installed inside the side of the transmission frame through a bearing.

[0009] Preferably, the bottom of the extraction pipe and the top of the side of the connecting bend are connected by a rotary joint, and the rotary joint is located on the lower outer side of the transmission frame.

[0010] Preferably, the rotating mechanism includes a rotating belt, a rotating rod is vertically rotatably mounted inside the end of the transmission frame away from the exhaust pipe via a bearing, a servo motor is fixedly mounted on the top of the outer side of the transmission frame, and the bottom of the servo motor transmission shaft is fixedly connected to the top of the rotating rod via a coupling, a transmission pulley is fixedly sleeved on the middle surface of the rotating rod, a follower pulley is fixedly sleeved on the outer side of the exhaust pipe, and a rotating belt is movably sleeved between the outer side of the transmission pulley and the outer side of the follower pulley.

[0011] Preferably, sliding blocks are fixedly installed at both ends of the side of the bearing plate, and a limiting groove is opened in the middle of the inner wall of the rotating groove, and the sliding blocks are slidably installed inside the limiting groove.

[0012] Preferably, a fixed frame is fixedly installed at the bottom of each sliding plate, a chamfered head is rotatably installed on the inner side of each fixed frame, and electric push rods are vertically fixedly installed on both sides of the top of the mounting frame, and the bottom of the electric push rod drive shaft is fixedly connected to the top of the outer side of the second electric guide rail.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. This utility model features a hollow support plate inside a processing table, with several sets of ventilation holes on the top of the support plate and an exhaust pipe connected to the bottom of the support plate. The exhaust pipe is connected to a vacuum pump located on the side of the bottom of the processing table via a connecting bend. Under the operation of the vacuum pump, a negative pressure is generated inside the support plate through the connecting bend and the exhaust pipe. This negative pressure creates a strong suction force on the outside of the ventilation holes. When chamfering the edges of the plywood, the plywood can be placed flat on the surface of the support plate. The negative pressure suction force on the surface of the support plate adsorbs and limits the plywood, achieving chamfering and fixing without obstructing the top edge of the plywood or interfering with the chamfering process, thus improving the stability of the plywood during chamfering and grinding.

[0015] 2. This utility model uses a rotary joint to rotatably connect the bottom of the extraction pipe and the top of the side of the connecting bend. The rotary joint itself rotates and connects, simultaneously connecting the transmission pulley and the follower pulley fixedly sleeved on the outside of the extraction pipe via a rotating belt. This allows the servo motor to drive the transmission pulley to rotate synchronously within the transmission frame, which in turn drives the follower pulley and the extraction pipe to rotate synchronously. This, in turn, causes the support plate to rotate synchronously within the processing table, adjusting the chamfered edges of the plywood adsorbed on its surface. This ensures the stability of the plywood placed on the support plate while further improving the efficiency of chamfering different edges on the top surface of the plywood.

[0025] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0026] Example 1: A chamfering device for facilitating plywood processing, see [link to example]. Figures 1 to 4 The processing table 1 has a rotating groove in the middle, and a bearing plate 2 is rotatably installed inside the rotating groove. The bearing plate 2 is hollow inside, and a vent hole 22 is opened on the top of the bearing plate 2. A sealing plunger 5 is movably inserted into the vent hole 22. The sealing plunger 5 can be inserted into the vent hole 22 to seal it. Thus, the number of vent holes 22 in the open state can be changed according to the size of the plywood to be processed. There are several sets of vent holes 22, and the vent holes 22 are circumferentially and evenly distributed on the top of the bearing plate 2. Through the hollow bearing plate 2 and the multiple sets of vent holes 22 on its surface, it can be ensured that the vacuum pump 26 can generate a corresponding negative pressure suction outside the vent holes 22 when it is running, thereby realizing the adsorption and fixation of the plywood.

[0027] For details, see Figures 1 to 4A vacuum pump 26 is fixedly installed on the bottom side of the processing table 1. A connecting bend 25 is fixedly connected to the side of the vacuum pump 26. The connecting bend 25 is located below the outside of the transmission frame 21, and the side of the connecting bend 25 is connected to the air inlet of the vacuum pump 26. A suction pipe 23 is vertically fixedly connected to the middle of the bottom of the support plate 2. The suction pipe 23 is rotatably installed inside the side of the transmission frame 21 through a bearing. The bottom of the suction pipe 23 and the top of the side of the connecting bend 25 are connected by a rotary joint 24. The rotary joint 24 is located below the outside of the transmission frame 21. The suction pipe 23 and the connecting bend 25 are connected through the rotary joint 24. With the rotational connection of the rotary joint 24, the suction pipe 23 remains connected to the connecting bend 25 when it is driven to rotate.

[0028] Further, see Figures 1 to 4 The processing table 1 has two fixedly mounted first electric slide rails 11 on its top sides. A mounting frame 12 is connected between the top of the first electric slide rails 11 via a transmission mechanism. A second electric slide rail 14 is movably mounted on the top inner side of the mounting frame 12. Sliding plates 15 are slidably mounted on both sides of the bottom of the second electric slide rail 14. Under electric drive, the first electric slide rails 11 and the second electric slide rail 14 can drive the mounting frame 12 or the sliding plates 15 to move horizontally synchronously. A fixed frame 16 is fixedly mounted on the bottom of each sliding plate 15, and a rotating mounting plate 15 is mounted inside each fixed frame 16. The frame has a chamfering head 17. A drive motor connected to the chamfering head 17 is provided on the top side of the fixed frame 16, so that it can provide the power required for the chamfering head 17 to rotate and grind the chamfer. Electric push rods 13 are vertically fixedly installed on both sides of the top of the mounting frame 12. The bottom of the drive shaft of the electric push rod 13 is fixedly connected to the top of the outer side of the second electric guide rail. Under the driving action of the first electric slide rail 11, the second electric slide rail 14 and the electric push rod 13, the chamfering position of the chamfering head 17 can be adjusted in multiple directions, thereby improving the chamfering quality of the plywood edge.

[0029] It is worth noting that, see Figures 1 to 4A rotating rod 3 is vertically mounted inside the transmission frame 21 at the end away from the exhaust pipe 23 via a bearing. A servo motor 34 is fixedly mounted on the top of the outer side of the transmission frame 21, and the bottom of the transmission shaft of the servo motor 34 is fixedly connected to the top of the rotating rod 3 via a coupling. A transmission pulley 31 is fixedly sleeved on the middle surface of the rotating rod 3. A follower pulley 32 is fixedly sleeved on the outer side of the exhaust pipe 23, and the follower pulley 32 is rotatably mounted inside the transmission frame 21. A rotating belt 33 is movably sleeved between the outer side of the transmission pulley 31 and the outer side of the follower pulley 32, and the rotating belt 33 is in a taut state between the transmission pulley 31 and the follower pulley 32. The transmission pulley 31 and the follower pulley 32 are connected by the rotating belt 33, so that when the servo motor 34 drives the transmission pulley 31 to rotate, the follower pulley 32 can still rotate synchronously, thereby providing the power required for the rotation of the exhaust pipe 23 and the support plate 2.

[0030] It is worth noting that, see Figures 1 to 4 Sliding blocks 41 are fixedly installed at both ends of the side of the bearing plate 2. A limiting groove 4 is opened in the middle of the inner wall of the rotating groove, and the sliding blocks 41 are slidably installed inside the limiting groove 4.

[0031] During operation, when chamfering and grinding the edges of the plywood is required, it is laid flat on the surface of the support plate 2. Several sets of sealing plungers 5 are then inserted into the vent holes 22 not yet covered by the plywood to seal them. The vacuum pump 26 is then turned on via an external control switch, causing it to operate and evacuate the interior of the support plate 2 through the connecting bend 25, rotary joint 24, and suction pipe 23. Combined with the airflow through the vent holes 22, the vacuum pump 26 generates negative pressure suction outside the vent holes 22, thereby removing air from the plywood covering the surface of the vent holes 22. After adsorption and fixation, the electric actuator 13 is activated, causing it to rotate and drive the second electric slide rail 14 and the chamfering head 17 at its bottom to move vertically in sync. This continues until the chamfering head 17 moves to the same horizontal plane as the edge of the plywood to be chamfered. Then, the second electric slide rail 14 is activated, causing it to rotate and drive the chamfering head 17 to move horizontally in opposite directions in sync. This continues until the side of the chamfering head 17 is fully in contact with the edge of the plywood. Finally, the drive motor and the first electric slide rail 11 are activated, allowing the chamfering head 17 to grind and chamfer the edge of the plywood while the first electric slide rail 11 drives the mounting frame 1. 2. The chamfering head 17 moves horizontally in sync to grind and chamfer the edges of the plywood. After grinding and chamfering both sides of the plywood, the chamfering head 17 is reset and moved away from the ground edges. Then, the servo motor 34 is started, causing the rotating rod 3 and the transmission pulley 31 to rotate synchronously inside the transmission frame 21. Combined with the synchronous driving action of the rotating belt 33 on the transmission pulley 31 and the follower pulley 32, the follower pulley 32 and the air extraction pipe 23 can be driven to rotate synchronously, thereby causing the bearing plate 2 to rotate synchronously inside the processing table 1, thus affecting its surface. While the plywood placed on the surface is rotated and adjusted for chamfering, the rotating joint 24 connects the suction pipe 23 and the connecting bend 25, ensuring that the suction pipe 23 keeps the carrier plate 2 rotating while the connecting bend 25 and the suction pipe 23 remain connected. The vacuum pump 26 can still adhere and fix the plywood through the connecting bend 25 and the suction pipe 23, allowing the plywood to rotate synchronously with the carrier plate 2, thus adjusting the chamfering position of the plywood. Repeating the above steps achieves chamfering and grinding of other edges.
