Description

Technical Field

[0001] This utility model relates to the field of sheet metal processing technology, and more specifically, to a pusher device for an edge banding machine. Background Technology

[0002] An edge banding machine is a type of woodworking machinery that automates the edge banding process of boards. It encompasses conveying, gluing, cutting, front and back trimming, top and bottom trimming, top and bottom fine trimming, top and bottom scraping, and polishing. Types include semi-automatic and handheld models. It is suitable for straight edge banding and trimming of various boards such as medium-density fiberboard (MDF) and plywood, producing delicate, smooth edges with straight lines. It is a crucial piece of equipment in custom furniture production. During operation, the board is first placed on a conveyor and transported to the gluing area. The gluing device evenly applies hot melt adhesive to the edge of the board. Next, the edge banding tape is fed from the tape reel and adheres to the glued edge of the board. After adhesion, the trimming device cuts off any excess tape extending beyond the board. Then, the fine trimming and scraping devices sequentially trim the edge, removing excess material and eliminating ripples. Finally, the polishing device sands the edge banding to make the end face smoother, completing the entire edge banding process.

[0003] However, in the current use of edge banding machines, existing conventional edge banding machines for narrow boards under 150mm can only be used as stand-alone machines and cannot be connected to an automated line. The edge banding machines are manually pushed one piece at a time, which is inefficient and produces poor edge banding results. Utility Model Content

[0004] To overcome the above deficiencies, this utility model provides a pusher device for an edge banding machine that overcomes or at least partially solves the above technical problems.

[0005] This utility model is implemented as follows:

[0006] This utility model provides a pusher device for an edge banding machine, including a wide synchronous belt conveyor, a narrow synchronous belt conveyor in front of the wide synchronous belt conveyor, a planetary reducer installed on the front left side of the narrow synchronous belt conveyor, a conveyor servo motor installed on the rear side of the planetary reducer, a flow strip assembly installed on the front side of the narrow synchronous belt conveyor, an electrical cabinet installed at the bottom of the narrow synchronous belt conveyor, a backing pusher mechanism installed on the rear side of the wide synchronous belt conveyor, and a lifting pressure roller mechanism located in front of the backing pusher mechanism installed on the rear side of the wide synchronous belt conveyor.

[0007] The backing pusher mechanism is used to provide a positioning reference for the sheet metal;

[0008] The lifting pressure roller mechanism is used to press the plate tightly, ensuring the stability of the plate during the conveying process;

[0009] The narrow synchronous belt conveyor is equipped with a concealed pusher on its top and a concealed baffle located to the right of the concealed pusher on its top.

[0010] In a preferred embodiment, the backrest pushing mechanism consists of a first backrest, a second backrest, and a third backrest that can be controlled independently. Each backrest is driven to push out and retract by a first cylinder, a second cylinder, and a third cylinder, respectively. Unsealed cylinders are installed on both sides of the rear side of the second backrest. The backrest pushing mechanism as a whole can be adjusted in front and back position by an external servo motor and a lead screw.

[0011] In a preferred embodiment, the lifting pressure roller mechanism consists of a first group of pressure rollers, a second group of pressure rollers, a third group of pressure rollers, and a fourth group of pressure rollers. Each group of pressure rollers consists of 15 rubber rollers with a diameter of 36mm. An encoder is installed on the rear side of the second group of pressure rollers, and a pressure roller lifting motor is also installed on the rear side of the encoder. An operation panel is installed on the rear side of the third group of pressure rollers.

[0012] The beneficial effects of the edge banding machine pusher device provided by this utility model include:

[0013] 1. By setting up a backrest pushing mechanism, a precise positioning benchmark can be provided for the board material, and the board material can be pushed to the required position. The entire backrest can also be driven by a servo to move the lead screw, so that the backrest can move back and forth to adapt to different working conditions. Like the fixed backrest, it adopts two layers of brand bearings, which are smoother than ordinary rollers, reduce friction, and increase service life.

[0014] 2. By setting up a lifting pressure roller mechanism, using more than 60 rubber rollers with a diameter of 36mm in a row, with 4-6 groups per row, and 15 pressure rollers in each group, for a total of 60-90 pressure rollers, the sufficient length is used for clamping and pushing the plate against the mountain, ensuring the stability of the plate conveying. This saves the need for the truss side-embedded pusher of conventional equipment. Each set of feeding pressure rollers is equipped with an independent cylinder, which can lift and lower independently. Each group of 15 pressure rollers is further divided into 5 subgroups, which are arranged in an alternating manner. Each subgroup is equipped with an independent spring buffer and 3 linear bearings to ensure the stability of the pressure rollers. The height of the entire row of pressure rollers is adjusted by a motor driving a screw.

[0015] 3. By setting up embedded pushers and embedded baffles, each machine can be equipped with 6 sets of embedded pushers. Each set of pushers is equipped with an angle adjustment limit screw, which can ensure that the contact surface between the pusher and the squared plate used for debugging is perfectly matched. Each machine is equipped with 6 sets of embedded baffles, and each set of embedded baffles is equipped with a buffer cylinder, which can allow slight deformation of the plate without affecting the edge sealing effect. Each set of baffle mechanisms is equipped with fiber optic sensors. Based on the plate length obtained by scanning the front end, several corresponding fibers must be sensed before proceeding to the next step. Otherwise, the machine will stop and alarm to prevent severely deformed plates or poorly fed plates from proceeding to the next pusher clamping plate and advancing movement, which could damage the equipment.

[0022] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0023] Reference Figures 1-4 This utility model provides a technical solution: an edge banding machine pusher device, including a wide synchronous belt conveyor 3 and a backing plate pusher mechanism 1. A narrow synchronous belt conveyor 6 is installed in front of the wide synchronous belt conveyor 3. A planetary reducer 24 is installed on the front left side of the narrow synchronous belt conveyor 6. A conveyor servo motor 23 is installed on the rear side of the planetary reducer 24. A flow strip assembly 7 is installed in front of the narrow synchronous belt conveyor 6. An electrical cabinet 8 is installed at the bottom of the narrow synchronous belt conveyor 6. The backing plate pusher mechanism 1 is installed in front of the wide synchronous belt conveyor 3. A lifting pressure roller mechanism 2 is installed in front of the backing plate pusher mechanism 1 in front of the wide synchronous belt conveyor 3. This can provide a precise positioning reference for the board and push the board to the required position. The entire backing plate can be driven by a servo to move the lead screw, so that the entire backing plate can move back and forth to adapt to different working conditions. Like the fixed backing plate, it adopts two layers of brand bearings, which are smoother than ordinary rollers, reduce friction, and increase service life.

[0024] Reference Figures 1-4In a preferred embodiment, the backing plate pushing mechanism 1 includes a first backing plate 9, which is composed of an independently controllable first backing plate 9, a second backing plate 11, and a third backing plate 12. Each backing plate is driven to push out and retract by a first cylinder 13, a second cylinder 14, and a third cylinder 15, respectively. Unsealed cylinders 10 are installed on both sides of the rear side of the second backing plate 11. The backing plate pushing mechanism 1 as a whole can be adjusted in front and back position by an external servo motor and a lead screw. During the operation of the edge banding machine, the first backing plate 9, the second backing plate 11, and the third backing plate 12 work together with the embedded pusher 4 and the embedded baffle 5 to achieve precise positioning of the plate. The first section of the support plate 9, the second section of the support plate 11, and the third section of the support plate 12, along with the first section of the cylinder 13, the second section of the cylinder 14, and the third section of the cylinder 15, can be moved as a whole by a servo motor. During edge sealing, the three cylinders work together or independently to push the plate to the edge sealing reference. When not sealing, they push it away from the reference. The embedded baffle 5, in conjunction with the buffer cylinder and fiber optic sensor, can adapt to slight deformation of the plate. It senses the plate length signal through fiber optics and stops the machine and alarms when there is an abnormality. The embedded pusher 4, with an angle adjustment limit screw, can fit completely with the square plate. The two work together to clamp the plate and ensure that it is pushed to the edge sealing reference, ensuring edge sealing accuracy and equipment safety. The lifting pressure roller mechanism 2 consists of the first group of pressure rollers 16, the second group of pressure rollers 17, the third group of pressure rollers 18, and the fourth group of pressure rollers 19. Each group of pressure rollers consists of 15 rollers. The system consists of 36mm diameter rubber rollers. An encoder 20 is installed on the rear side of the second set of pressure rollers 17, and a pressure roller lifting motor 21 is also installed on the rear side of the encoder 20. An operation panel 22 is installed on the rear side of the third set of pressure rollers 18. It uses more than 60 36mm diameter rubber rollers in one row, with 4-6 groups per row and 15 pressure rollers in each group, for a total of 60-90 pressure rollers. The rollers are long enough to clamp and push the plates, ensuring the stability of the plate conveying. This saves the need for the truss-side embedded pusher 4 of conventional equipment. Each set of feeding pressure rollers is equipped with an independent cylinder for independent lifting. Each group of 15 pressure rollers is further divided into 5 subgroups, which are staggered. Each subgroup is equipped with an independent spring buffer and 3 linear bearings to ensure the stability of the pressure rollers. The height of the entire row of pressure rollers is adjusted by a motor-driven screw.

[0025] Specifically, the working process or principle of the edge banding machine's pusher device is as follows: During use, the board material is conveyed from an external device, such as a slanted roller conveyor or a belt conveyor. The scanning mechanism at the inlet determines whether the board material is to be edge-banded (either 1) or (2) in this case. Edge banding is further divided into A: banding the long edge, and B: banding the short edge. If edge banding is not desired (1), the inlet conveyor will push the board material 50mm away from the edge banding reference. This device only requires the pressure roller group to be moved to the appropriate position, and the wide synchronous belt conveyor (3) and narrow synchronous belt conveyor (6) will simultaneously feed the board into the edge banding machine. Because the board material deviates from the edge banding reference, Therefore, edge sealing will not be required. The concealed pusher 4 and concealed baffle 5 do not need to move. 2A: For sealing long edges, the material requirements are a length ≥ 250 and a width ≥ 45. When the material arrives, the three cylinders of the first section (mountain 9), the second section (mountain 11), and the third section (mountain 12) move together. At this time, the reference of the mountain is the same as the reference of the edge sealing machine. The pressure roller group moves to the appropriate position, and the wide synchronous belt conveyor 3 and the narrow synchronous belt conveyor 6 move synchronously to feed the board into the edge sealing machine to complete the edge sealing. B: When sealing short edges, a: When the material length ≥ 250 and 300 ≤ width, the first section... The three cylinders of the first section (mountain 9), the second section (mountain 11), and the third section (mountain 12) operate together. At this time, the reference of the mountain is the same as the reference of the edge banding machine. The pressure roller group moves to the appropriate position, and the wide synchronous belt conveyor 3 and the narrow synchronous belt conveyor 6 operate synchronously to feed the board into the edge banding machine to complete the edge banding; b: When the board length is ≥250 and the width is 45≤300, this is defined as a narrow board. This equipment is developed to complete the edge banding of this type of board. When the board comes in, the first section (mountain 9) and the cylinder do not operate. At this time, the reference of the first section (mountain 9) differs from the reference of the edge banding machine. When the pressure roller group moves to the appropriate position, the wide synchronous belt conveyor 3 and the narrow synchronous belt conveyor 6 move synchronously to feed the plate into the first section of the support plate 9. According to the barcode scanning mechanism at the feed port, the embedded baffle 5 will move to a certain distance at the front end of the plate. The embedded pusher 4 moves to push the plate in front of the baffle of the embedded baffle 5 to complete the clamping. When all sensors are normal and there is no alarm, the first cylinder 13 and the second cylinder 14 of the second section of the support plate 11 and the third section of the support plate 12 move simultaneously to push the plate to the support plate reference of the edge banding machine. The plate then enters the edge banding machine to complete the edge banding.

[0026] It should be noted that the wide synchronous belt conveyor 3, the narrow synchronous belt conveyor 6, the planetary reducer 24, the conveyor servo motor 23, the electrical cabinet 8, the first-stage cylinder 13, the second-stage cylinder 14, the third-stage cylinder 15, the encoder 20, and the pressure roller lifting motor 21 are existing devices or equipment, or devices or equipment that can be implemented with existing technology. Their power supply, specific composition, and principles are clear to those skilled in the art, so they will not be described in detail.
