Description

Technical Field

[0001] This utility model belongs to the field of folder parts processing technology, and in particular relates to a folder elastic buffer structure forming and processing equipment. Background Technology

[0002] The elastic cushioning structure of a folder is an important component. After molding, its surface often has burrs, requiring polishing with specialized equipment to ensure smooth assembly and a pleasant feel during use. Currently, polishing of these parts is mostly done using equipment with conveying and polishing functions. The conveyor structure moves the workpiece, and the polishing components work together to process the surface. This type of equipment is widely used in folder manufacturing workshops.

[0003] Existing grinding equipment has several limitations in practical use. In some devices, the grinding components are in fixed positions, requiring frequent adjustments when dealing with workpieces of varying thicknesses. Over time, the grinding plate wears down and may lose contact with the workpiece surface, leading to incomplete grinding. Furthermore, the lack of effective limiting during workpiece transport makes it prone to slippage during grinding, affecting grinding accuracy. Therefore, a folder-based elastic buffer structure forming and processing equipment is proposed. Utility Model Content

[0004] The purpose of this invention is to provide a folder elastic buffer structure forming and processing equipment. The equipment can process workpieces of various specifications without frequent adjustments, which greatly improves the adaptability and flexibility of the equipment and solves the existing technical problems.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: A folder elastic cushioning structure forming and processing equipment includes: a frame, and two spaced conveying mechanisms are provided on the top of the frame; A mounting box is fixedly connected to one side of the frame, and a through sliding frame is slidably connected to one side of the mounting box. A mounting plate is fixedly connected to one end of the sliding frame. Two symmetrically arranged rotating shafts are rotatably connected to one side of the mounting plate. A grinding plate is fixedly connected to one side of each rotating shaft. A torsion spring is fixedly installed between the rotating shaft and the mounting plate. The two grinding plates are inclined and symmetrically arranged. The two grinding plates are arranged in a figure-eight shape with the larger opening facing the workpiece. The drive mechanism, housed within the mounting box, is used to drive the sliding frame to move.

[0006] As a further embodiment of this utility model, the conveying mechanism includes two conveying rollers, both of which are rotatably connected between the two sides of the top of the frame, and a conveyor belt is driven between the conveying rollers; Two grinding plates are located between two conveyor belts.

[0007] As a further embodiment of this utility model, two through pressure rollers are rotatably connected to one side of the mounting box. A gap is provided between the pressure rollers and the corresponding conveyor belt surface for the workpiece to pass through. The two pressure rollers are located on both sides of the grinding plate. One end of the two pressure rollers and the circumference of the two adjacent conveyor rollers are fixedly connected to a first gear, and the two adjacent first gears mesh.

[0008] As a further embodiment of this utility model, the driving mechanism includes a side frame and a guide rail. The side frame is fixed to the inner wall of one side of the mounting box. A driven shaft is rotatably connected to one side of the side frame. A drive disk is fixedly connected to one end of the driven shaft. An eccentrically mounted drive shaft is fixedly connected to one side of the drive disk. The guide rail is fixed to the inner wall of one side of the mounting box. A slider is slidably connected inside the guide rail. A push-pull rod is rotatably connected between the slider and the drive shaft. A support rod is rotatably connected between the slider and the sliding frame.

[0009] As a further embodiment of this utility model, the circumference of the driven shaft and one end of one of the conveying rollers are fixedly connected to a second gear, and the two second gears mesh.

[0010] As a further embodiment of this utility model, two motors are fixedly connected to one side of the frame, and one end of the output shaft of each motor is fixed to one of the two conveying rollers respectively.

[0011] Working principle: The motor drives the conveyor belt to transport the workpiece. When the workpiece passes through the rubber pressure rollers, it is pressed above the conveyor belt and kept in a conveying state. As the conveyor rollers rotate, one of the conveyor rollers drives the driven shaft to rotate through the second gear. The driven shaft drives the drive disc to rotate. The drive disc drives the push-pull rod to move back and forth through the eccentrically mounted drive shaft. The push-pull rod drives the slider to move back and forth. The slider pushes the sliding frame to move back and forth through the support rod. The sliding frame drives the rotating shaft and the grinding plate to move through the mounting plate. The grinding plate grinds the workpiece to remove burrs. At the same time, under the action of the torsion spring, one end of the grinding plate can always be in contact with the workpiece, which can adapt to workpieces of different thicknesses. Even after the grinding plate is worn, it can still contact the workpiece. The setting of the pressure rollers can restrict the workpiece and prevent it from slipping during grinding.

[0012] The embodiments of this utility model have the following beneficial effects: In this invention, the torsion spring, grinding plate, and adjustable gap pressure roller work together. The torsion spring keeps the grinding plate in constant contact with the workpiece surface, adapting to differences in workpiece thickness and wear. The gap of the pressure roller can be adjusted by adding or removing shims to accommodate different workpieces. The equipment can process workpieces of various specifications without frequent adjustments, significantly improving its adaptability and flexibility. In this invention, the conveying roller, the second gear, and the drive mechanism work together to transmit power from the conveying roller to the driven shaft via the second gear, thereby driving the grinding plate to reciprocate. This linkage design eliminates the need for an additional drive source for the grinding mechanism, simplifying the overall structure of the equipment while reducing energy consumption. It also enables synchronization of workpiece conveying and grinding actions, improving processing efficiency.

[0013] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0018] To keep the following description of the embodiments of this utility model clear and concise, detailed descriptions of known functions and known components are omitted.

[0019] In one embodiment: Please refer to Figures 1-5 As shown, this embodiment provides a processing device, including: a basic support structure of the device is a frame 1, with multiple support legs fixed at the bottom. Leveling pads can be added according to actual usage requirements to ensure the stability of the device during placement and prevent shaking during operation from affecting processing accuracy. At the top of the frame 1, two conveying mechanisms 2 are spaced apart along its length for smoothly conveying the workpiece.

[0020] Each conveying mechanism 2 consists of two conveying rollers 3 and a conveyor belt 4. The two conveying rollers 3 are rotatably connected to the top sides of the frame 1 via deep groove ball bearings. The axes of the conveying rollers 3 are arranged along the width of the frame 1, and the heights of the two conveying rollers 3 are consistent. The conveyor belt 4 is made of polyurethane material with a fine anti-slip texture on its surface. The conveyor belt 4 is fitted between the two conveying rollers 3 of the same conveying mechanism 2, and the rotation of the conveying rollers 3 drives the conveyor belt 4 to form a cyclic conveying action. To ensure the tension of the conveyor belt 4 during operation...

[0021] A mounting box 5 is bolted to one side of the frame 1 along its length. The mounting box 5 is a rectangular box structure with a cavity on one side, facing the direction of the conveying mechanism 2. Two circular mounting holes are provided on the panel of the mounting box 5 near the conveying mechanism 2. Two pressure rollers 6 are rotatably connected to these two mounting holes via rolling bearings. The axis of the pressure rollers 6 is parallel to the axis of two of the conveying rollers 3. Each pressure roller 6 corresponds to a conveyor belt 4 of the conveying mechanism 2. A gap is reserved between the outer surface of the pressure roller 6 and the upper surface of the lower conveyor belt 4 to accommodate the workpiece thickness, ensuring that workpieces of different thicknesses can pass smoothly and be stably pressed. The pressure rollers 6 are made of rubber, with a certain degree of elasticity, which can effectively press the workpiece while avoiding indentation damage to the workpiece surface.

[0022] On the shaft section extending from one end of the pressure roller 6 into the mounting box 5, and on the shaft section extending from the frame 1 of the adjacent conveyor roller 3, first gears 7 are fixedly connected by flat keys. The two adjacent first gears 7 have the same number of teeth and mesh with each other. When the conveyor roller 3 rotates, it drives the pressure roller 6 to rotate synchronously through the meshing first gears 7. The rotation direction of the pressure roller 6 is opposite to the running direction of the conveyor belt 4. In this way, when the workpiece passes through the gap between the pressure roller 6 and the conveyor belt 4, the clamping and conveying action formed by the pressure roller 6 and the conveyor belt 4 can further improve the stability of the workpiece conveying and prevent the workpiece from shifting during the subsequent grinding process.

[0023] On the panel of the mounting box 5 near the conveying mechanism 2, two rectangular guide holes are provided. The sliding frame 17 is a cuboid and slides through these rectangular guide holes. The sliding frame 17 is located at one end outside the mounting box 5 and is fixedly connected to the mounting plate 18 by welding. The mounting plate 18 is a rectangular plate, and its surface is perpendicular to the axis of the sliding frame 17. On the side of the mounting plate 18 facing the conveying mechanism 2, two rotating shafts 19 are rotatably connected by two symmetrically arranged bearing seats. The axes of the two rotating shafts 19 are parallel to each other.

[0024] Each rotating shaft 19 has a grinding plate 21 bolted to its side near the conveying mechanism 2. A torsion spring 20 is fixedly installed between the rotating shaft 19 and the bearing seat of the mounting plate 18, sleeved on the shaft section of the rotating shaft 19. Under the natural elastic force of the torsion spring 20, the two grinding plates 21 are arranged in an inclined and symmetrical manner, forming a figure-eight structure. The end with the larger opening faces the conveying direction of the workpiece, while the end with the smaller opening faces away from the conveying direction. This allows the workpiece to smoothly enter between the two grinding plates 21 during conveying, while the elastic force of the torsion spring 20 ensures that the grinding surface of the grinding plate 21 remains in close contact with the workpiece surface. Even if there are slight differences in workpiece thickness or the grinding plate 21 experiences some wear, a stable grinding effect can be guaranteed. The two grinding plates 21 are positioned precisely between the conveyor belts 4 of the two conveying mechanisms 2, ensuring accurate application to the parts of the workpiece that need grinding.

[0025] This application can be used in the field of folder parts processing, or in other fields applicable to this application.

[0026] In another embodiment: refer to Appendix Figures 1-5 A folder elastic cushioning structure forming and processing equipment includes: it is applied to the field of folder parts processing. The structure of this embodiment is basically the same as that of the aforementioned embodiments, except that: The mounting box 5 houses a drive mechanism for driving the sliding frame 17 to reciprocate linearly along the guide hole. This drive mechanism includes a side frame 8, a driven shaft 9, a drive disc 10, a drive shaft 11, a guide rail 12, a slider 13, a push-pull rod 14, and a support rod 16. The side frame 8 is an L-shaped steel plate, bolted to the inner wall of one side of the mounting box 5. The driven shaft 9 is rotatably connected to one side of the side frame 8 via bearings. The drive disc 10 is a circular disc, fixed to one end of the driven shaft 9 by a flat key, with the end face of the drive disc 10 perpendicular to the axis of the driven shaft 9. The drive shaft 11 is a short cylindrical shaft, one end of which is eccentrically mounted on the end face of the drive disc 10 away from the driven shaft 9 by welding. This eccentricity determines the reciprocating stroke of the sliding frame 17.

[0027] The guide rail 12 is a T-shaped guide rail, fixed to the inner wall of the mounting box 5 on the side away from the sliding frame 17 by bolts, and its length direction is consistent with the sliding direction of the sliding frame 17. The slider 13 is a sliding block that matches the T-shaped guide rail. The slider 13 is engaged with the guide rail 12 and can slide smoothly along the guide rail 12. Lubricant is applied between the guide rail 12 and the slider 13 to reduce sliding friction. One end of the push-pull rod 14 is rotatably connected to the drive shaft 11, and the other end is rotatably connected to the slider 13. One end of the support rod 16 is rotatably connected to one side of the slider 13 by a pin, and the other end is rotatably connected to the end of the sliding frame 17 that extends into the mounting box 5 by a pin.

[0028] On the circumference of the driven shaft 9, and on the shaft section where one of the conveyor rollers 3 extends from the frame 1 into the mounting box 5, two second gears 15 are fixedly connected by flat keys. The two second gears 15 mesh with each other, thereby realizing the synchronous transmission of power from the conveyor roller 3 to the driven shaft 9. On one side of the frame 1, two servo motors are fixedly connected by motor mounting brackets. The output shafts of the two motors are respectively fixedly connected to the conveyor rollers 3 on the side of the two conveying mechanisms 2 away from the mounting box 5 through flexible couplings. The motors rotate synchronously, and the speed can be adjusted by a frequency converter to adapt to different workpiece grinding requirements.
