Description

Technical Field

[0001] This invention relates to the field of edge banding devices for sheet metal, and more particularly to a rotary working device for an edge banding machine. Background Technology

[0002] Currently, the edge banding process for boards requires first using an edge banding device to adhere the edge banding tape to the edge of the board, followed by a trimming device to trim the edge banding tape. Traditional edge banding machines generally adopt a fixed linear worktable assembly line layout. Traditional edge banding and trimming devices often occupy a large space, resulting in a relatively dispersed overall layout. Handling boards not only increases workload and working time but also increases the risk of damage during board handling.

[0003] Currently, there are designs on the market that integrate sealing and trimming devices into one piece of equipment. For example, patent CN108972830A proposes a dual-station edge sealing and trimming device. By setting the edge sealing and trimming devices at both ends of the support platform, the independent rotating structure of the edge sealing and trimming devices makes the overall structure of the equipment complex, which not only increases the manufacturing cost, but also reduces the long-distance handling of the board material in terms of process connection. However, it still requires the use of structures such as swing arms to move the board material from the trimming station to the edge sealing station, which to some extent affects the speed and efficiency of process changeover. Summary of the Invention

[0004] In order to overcome the shortcomings of the prior art, one of the objectives of this invention is to provide a rotary working device for an edge banding machine, which solves the technical problems of existing devices having complex structures, high manufacturing costs, and low process conversion efficiency due to the need to move the board to different work positions.

[0005] One of the objectives of this invention is achieved through the following technical solution: A rotary working device for an edge banding machine, comprising: A rotating working structure includes a support platform and a worktable, wherein an edge sealing device and an edge trimming device are respectively provided at both ends of the worktable; A rotary drive structure configured to connect the support platform and the worktable to rotatably mount the worktable on the support platform.

[0006] A rotary locking structure is fixedly disposed on the worktable, and the rotary locking structure is configured to abut against the support platform to fix the two ends of the worktable to the preset working position of the support platform.

[0007] Based on the above technical solution, the present invention is further described as follows: The support platform is symmetrically arranged with two workstation positions; The edge sealing device and the edge trimming device are symmetrically arranged at both ends of the workbench; The rotating locking structure fixes the two ends of the workbench to the two workstation positions respectively.

[0009] As a further embodiment of this utility model, the rotary locking structure includes: A brake cylinder, wherein at least one set of brake cylinders is provided, and the brake cylinders are located on the lower side of the worktable. As a further embodiment of this invention, the slewing support bearing is disposed in the middle of the worktable. The brake cylinders are provided in four parts, and the brake cylinders are distributed around the slewing support bearing.

[0010] As a further aspect of this utility model, it also includes: A dustproof structure, comprising a dustproof protective shell, the dustproof protective shell comprising at least one set of dustproof plates, adjacent dustproof plates being connected end to end to form the dustproof protective shell, and the slewing support bearing being disposed inside the dustproof protective shell.

[0014] As a further embodiment of this utility model, the plate auxiliary support arm is provided in two parts and is symmetrically arranged on the support platform.

Detailed Implementation

[0017] Below, in conjunction with the appendix Figure 1 To be continued Figure 5 The present invention will be further described in detail below with specific implementation methods. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0018] A rotary working device for an edge banding machine includes a rotary working structure 1, a rotary drive structure 2, a rotary locking structure 3, an auxiliary reinforcement structure 4, a dustproof structure 5, and a conveyor belt structure 6. The rotary working structure 1 carries an actuator that performs edge banding and trimming functions, enabling edge banding and trimming operations on the board material. The rotary drive structure 2 rotates the rotary working structure 1, allowing switching between edge banding station 14 and trimming station 15. The rotary locking structure 3 applies a locking force to the interior of the rotary working structure 1, thereby achieving pre-locking. The edge banding station 14 and trimming station 15 are positioned to enhance the load-bearing capacity of the rotating working structure 1 and the frictional engagement with the rotating locking structure 3, further increasing the constraint force on the interior of the rotating working structure 1. The dustproof structure 5 can also be used to protect the rotating locking structure 3, thereby extending its lifespan. The edge banding tape is continuously supplied through the tape feeding structure 6, eliminating the risk of interference with the rotating motion. This improves the process adaptability of complex contour plates and significantly enhances the space utilization and processing efficiency of the production line.

[0019] For details, please refer to the appendix. Figure 1 and attached Figure 4The rotating operating structure 1 includes a workbench 11 and a support platform 12. The workbench 11 is rotatably mounted on the support platform 12. The workbench 11 is equipped with at least one set of edge-sealing operating devices 13. The workbench 11 is configured as a rectangular box. The edge-sealing operating device 13 includes an edge-sealing device 131 and an edge-trimming device 132. The edge-sealing device 131 and the edge-trimming device 132 are respectively integrated at both ends of the workbench 11. The rigid structure of the rectangular box is used to realize the installation function of the edge-sealing operating device 13. At the same time, the rectangular workbench 11 is used to realize the symmetrical workstation position distribution of the edge-sealing device 131 and the edge-trimming device 132, thereby improving the operating efficiency.

[0020] Please refer to the attached document. Figure 2 and attached Figure 4 The support platform 12 is configured as a symmetrical octagonal box. The distance between one pair of opposite sides of the support platform 12 is adapted to the length of the long side of the workbench 11. This pair of opposite sides is defined as the first pair of opposite sides. The side adjacent to the first pair of opposite sides is the second pair of opposite sides 122, and the side adjacent to the second pair of opposite sides 122 is the second pair of opposite sides 123. The length of the first pair of opposite sides is adapted to the length of the short side of the workbench 11. When the end of the workbench 11 is rotated to the first pair of opposite sides, the edge sealing device 131 and the edge trimming device 132 are respectively located at the edge of the first pair of opposite sides, and the second pair of opposite sides 122 are close to the edge sealing device 131 and the edge trimming device 132. The side where position 132 is located is the workstation position. The workstation position can be set up in two symmetrical groups, which are divided into edge banding workstation 14 and edge trimming workstation 15. When one group of workstations performs edge banding operation, the other group of workstations performs edge trimming operation, so as to realize the parallel and switching function of edge banding and edge trimming processes. The process conversion of the same workstation is completed by rotating the worktable 11 180 degrees. At the same time, relying on the dual operation function design of a single workstation, the edge banding and edge trimming operations can be switched by rotating the worktable of one workstation position, avoiding the process of transferring the board material, reducing the equipment footprint, and improving space utilization and production continuity.

[0021] Please refer to the attached document. Figure 2 The support platform 12 also includes a plate auxiliary support arm 16. The fixed end of the plate auxiliary support arm 16 is disposed at the end of the support platform 12. In this embodiment, there are two plate auxiliary support arms 16, which are symmetrically disposed at the adjacent corners of the second opposite sides 123 and the second opposite sides 122. They do not affect the rotation of the worktable 11, so as to achieve interference-free cooperation with the rotational movement of the worktable 11 and ensure the safety of the device operation.

[0022] Please refer to the attached document. Figure 1 and attached Figure 3The rotary drive structure 2 is disposed between the worktable 11 and the support platform 12. The worktable 11 is rotatably mounted on the support platform 12 via the rotary drive structure 2. Specifically, the rotary drive structure 2 includes a drive motor 21 and a rotary support bearing 22. The drive motor 21 is fixedly mounted above the lower side panel of the worktable 11. The output shaft of the drive motor 21 extends from above the lower side panel of the worktable 11 below the lower side panel, and a drive gear is provided at the lower end of the output shaft of the drive motor 21. The rotary support bearing 22 transmits power to the drive gear. Specifically, the rotary support bearing 22 is located in the middle of the worktable 11. The rotary support bearing 22 is equipped with an external gear, which meshes with the drive gear. The upper end of the rotary support bearing 22 is fixedly connected to the lower end of the worktable 11 by multiple sets of bolts, and the lower end of the rotary support bearing 22 is fixedly connected to the upper side of the support platform 12 by multiple sets of bolts. This is to provide rotational power through the transmission between the drive motor 21 and the drive gear. The rotary support bearing 22 enables the relative rotation of the worktable 11 and the support platform 12, ensuring the rotational reliability of the worktable 11.

[0023] Please continue to refer to the appendix. Figure 3 The rotary locking structure 3 includes a telescopic member 31, which includes, but is not limited to, a brake cylinder. The telescopic member 31 is located below the lower side panel of the worktable 11. It is configured to abut against the support platform 12 to fix the edge-sealing device 131 to a preset position on the worktable 11. This allows the drive motor 21 to rotate the worktable 11 to a specified angle and position. The abutment between the telescopic member 31 and the support platform 12 then achieves a rigid locking function for the worktable 11, ensuring its structural stability and preventing processing errors caused by worktable 11 wobbling. The rotary support bearing 22 is located in the middle of the worktable 11. Four brake cylinders are arranged around the rotary support bearing 22. This arrangement of the rotary support bearing 22 in the middle provides balanced force support to the worktable 11, while the surrounding brake cylinders create a symmetrical locking force, improving the overall rigidity and locking reliability of the rotary drive structure 2.

[0024] Please refer to the attached document. Figure 4 It also includes an auxiliary reinforcement structure 4, which includes an upper cover plate 41. The upper cover plate 41 is disposed on the upper side of the support platform 12. The upper side of the upper cover plate 41 is abutted and fitted with the movable end of the brake cylinder to enhance the strength of the upper side of the support platform 12 and at the same time enhance the friction between the movable end of the brake cylinder and the support platform 12, thereby improving the locking stability of the locking structure.

[0025] Please continue to refer to the appendix. Figure 4 It also includes a dustproof structure 5, which includes a dustproof protective shell 51. The dustproof protective shell 51 includes at least one set of dustproof plates, with adjacent dustproof plates connected end-to-end to form the dustproof protective shell 51. The rotary support bearing 22 is disposed inside the dustproof protective shell 51, and the lower end of the dustproof plate is fixed to the support platform 12. The dustproof protective shell 51 effectively isolates the rotary support bearing 22 from dust, thereby improving the anti-fouling capability of the rotary drive structure 2 and extending the maintenance cycle and service life of the rotary drive structure.

[0026] Please refer to the attached document. Figure 1 and attached Figure 5 The system also includes a tape feeding structure 6, which comprises a tape support 61 and a tape reel unit 62. Specifically, the tape support 61 is fixedly mounted on the workbench 11 and is configured as a vertical rod. The tape reel unit 62 comprises a hanging plate 621, a tape body 622, a clamping frame 623, and a limiting locking component 624. One side of the hanging plate 621 is vertically fixedly mounted on the upper end of the tape support 61. A central shaft 6211 protrudes from the other side of the hanging plate 621. A rotating sleeve 6212 is provided on one end of the central shaft 6211 near the hanging plate 621. The rotating sleeve 6212 is rotatably engaged with the central shaft 6211 via a bearing. A through hole 6221 is provided in the middle of the tape body 622, through which the tape body 622 is sleeved onto the rotating sleeve 6212. On the outer side surface, the inner side surface of the sealing strip body is fitted to the hanging plate 621. The clamping frame 623 is disposed on the outer side surface of the sealing strip body 622. The clamping frame 623 includes a sleeve 6231 and a plurality of limiting rods 6232 surrounding the sleeve 6231. The sleeve 6231 is sleeved on the outer end of the rotating sleeve 6212, and the sleeve 6231 is provided with a through hole 62 for the central shaft 6211 to pass through. 33. The central shaft 6211, through the second through hole 6233, is provided with a limiting locking component 624. The limiting locking component 624 may be, but is not limited to, a shaft locking device or a locking ring. The limiting locking component 624 is fixedly mounted on the central shaft 6211 and abuts against the outer side of the clamping frame 623 to clamp the edge sealing tape 622 between the clamping frame 623 and the hanging plate 621. This allows for the free feeding function of the edge sealing tape 622 through the rotational engagement of the central shaft 6211 and the rotating sleeve 6212. The clamping and fixing of the clamping frame 623 and the limiting locking component 624 achieves axial positioning of the disc, improving the coaxiality and stability of the tape feeding process. At the same time, the detachable locking structure enables quick replacement of the edge sealing tape 622, improving the material changing efficiency of the equipment.
