Description

Technical Field

[0001] This utility model relates to the technical field of shoe insole production equipment, specifically a high-frequency welding machine for shoe insole production. Background Technology

[0002] In the field of insole production, high-frequency welding machines are the core equipment for embossing and welding insole fabrics. They use high-frequency electromagnetic fields to polarize the fabric molecules and generate heat, simultaneously completing pattern embossing and edge cutting, which directly determines the appearance, texture and molding precision of the insole.

[0003] Currently, most mainstream high-frequency welding machines adopt a single-station or double-station fixed structure. During production, the fabric to be processed needs to be placed at the station one by one manually. After the embossing and welding are completed, the finished product is removed manually. This mode has significant drawbacks: the production process is frequently interrupted by manual loading and unloading, making it impossible to achieve continuous operation. The production efficiency can only meet the needs of small batches. Repetitive manual operation not only increases labor costs, but also easily causes safety hazards due to fatigue. It is difficult to adapt to the high-efficiency and stable requirements of large-scale shoe insole production. Utility Model Content

[0004] (a) Technical problems to be solved To address the shortcomings of existing technologies, this utility model provides a high-frequency welding machine for insole production.

[0005] (II) Technical Solution To achieve the above objectives, this utility model provides the following technical solution: a high-frequency welding machine for insole production, comprising a processing table and an embossing assembly, the embossing assembly being located above a base, a control box being fixedly installed at the upper end of the processing table, an annular cylinder penetrating the processing table being provided at the lower end of the base, the annular cylinder being rotatably connected to the processing table via bearings, a gear ring being fixedly installed at the bottom of the annular cylinder, a motor being fixedly installed below the processing table, and a gear meshing with the gear ring being provided at the output end of the motor; The upper end of the base is provided with a detachable bottom mold, the bottom mold is provided with multiple mold grooves, the middle part of the bottom mold is provided with a hollow groove, the inside of the hollow groove is fixedly provided with a propulsion component, the output end of the propulsion component is provided with a discharge plate, the discharge plate is located above the bottom mold, and the side of the processing table is provided with a discharge port.

[0006] Furthermore, the present invention includes an improvement in that the embossing assembly includes a lifting assembly and a pressure plate, the lifting assembly being fixed above the base, and the pressure plate being fixed at the output end of the lifting assembly.

[0007] To improve the stability of the base during use, the present invention includes an improvement where multiple ball bearings are rolled at the lower end of the base to contact the upper surface of the processing table, providing an auxiliary support structure for the base.

[0008] To facilitate assembly of the propulsion assembly, the present invention includes an improvement in which the propulsion assembly is fixed above the empty slot by a support rod, and the bottom end of the support rod is fixed to the bottom of the empty slot by screws.

[0009] To facilitate assembly of the bottom mold, the present invention includes the following improvements: the upper end of the base is provided with multiple positioning grooves, and the lower end of the bottom mold is provided with multiple positioning blocks inserted into the positioning grooves. The positioning blocks are rectangular in structure and have limiting holes on their inner sides. The lower end of the base is provided with multiple sliding grooves, and sliders are slidably arranged in the sliding grooves. The front end of the sliders is provided with limiting rods inserted into the limiting holes. A movable seat is provided below the processing table, and multiple drive rods are symmetrically arranged around the movable seat.

[0010] To improve the stability of the slider during sliding, the present invention includes the following improvements: two guide grooves are symmetrically arranged on the inner wall of the slide groove, and guide blocks are provided on both sides of the slider, which are inserted into the guide grooves and slidably connected to the guide grooves.

[0011] (III) Beneficial Effects Compared with the prior art, this utility model provides a high-frequency welding machine for insole production, which has the following advantages: Through the transmission structure of "motor-gear-gear ring-ring cylinder-bearing", the base is driven to rotate stably. With the help of multiple mold grooves on the bottom mold, the feeding, embossing and unloading processes can be completed simultaneously, which completely solves the drawback of "production interruption" in traditional fixed workstations. In addition, the automatic unloading function replaces manual material handling, reduces manual operation links, and significantly improves production efficiency compared with traditional equipment, making it suitable for the needs of large-scale shoe insole production.

[0012] With the help of the linkage structure of "threaded rod-moving seat-drive rod-slider-limiting rod", the bottom mold can be fixed and disassembled by simply rotating the threaded rod. No complicated tools are required. The cooperation between the positioning groove and the positioning block can quickly align the bottom mold position, which greatly shortens the time for switching between different specifications of insoles, enhances the versatility of the equipment, and reduces the mold change cost for multi-variety production.

[0014] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Please see Figures 1-5 This utility model proposes a high-frequency welding machine for shoe insole production, including a processing table 1 and an embossing assembly. The embossing assembly is located above a base 5. A control box 2 is fixedly installed at the upper end of the processing table 1. An annular cylinder penetrating the processing table 1 is provided at the lower end of the base 5. The annular cylinder and the processing table 1 are rotatably connected by a bearing. A gear ring 6 is fixedly installed at the bottom of the annular cylinder. A motor 7 is fixedly installed below the processing table 1. A gear 8 that meshes with the gear ring 6 is provided at the output end of the motor 7. The upper end of the base 5 is provided with a detachable bottom mold 9. The bottom mold 9 is provided with multiple mold grooves 10. The middle part of the bottom mold 9 is provided with a hollow groove 14. A propulsion component 15 is fixedly installed inside the hollow groove 14. The output end of the propulsion component 15 is provided with a discharge plate 16. The discharge plate 16 is located above the bottom mold 9. A discharge port is provided on one side of the processing table 1.

[0016] First, assemble the bottom mold 9 and the base 5: The upper end of the base 5 is provided with multiple positioning grooves 11, and the lower end of the bottom mold 9 is provided with multiple positioning blocks 12 inserted into the positioning grooves 11. The positioning blocks 12 are rectangular in structure and have limiting holes on their inner sides. The lower end of the base 5 is provided with multiple sliding grooves 17, and sliders 18 are slidably arranged in the sliding grooves 17. The front end of the sliders 18 is provided with limiting rods 13 inserted into the limiting holes. The processing table 1 is provided with a movable seat 19 below it. Multiple drive rods 21 are symmetrically arranged around the movable seat 19. The bottom end of the drive rods 21 is hinged to the movable seat 19, and the top end of the drive rods 21 is hinged to the rear end of the sliders 18. A threaded rod 20 is vertically rotatably arranged at the lower end of the base 5. The threaded rod 20 passes through the movable seat 19 and is threadedly connected to the movable seat 19.

[0017] Two guide grooves are symmetrically arranged on the inner wall of the slide groove 17, and guide blocks are provided on both sides of the slider 18, which are inserted into the guide grooves and slidably connected to the guide grooves.

[0018] Align the positioning block 12 at the lower end of the bottom mold 9 with the positioning groove 11 at the upper end of the base 5 and insert it to ensure that the bottom mold 9 is initially positioned. Then rotate the threaded rod 20 at the lower end of the base 5 clockwise. The threaded rod 20 engages with the movable seat 19 below the processing table 1, causing the movable seat 19 to rise along the threaded rod 20. When the movable seat 19 rises, the drive rod 21 hinged to its periphery pushes the slider 18 to slide along the slide groove 17 of the base 5. The guide blocks on both sides of the slider 18 slide synchronously along the guide groove on the inner wall of the slide groove 17 to ensure stability. Finally, the limiting rod 13 at the front end of the slider 18 is inserted into the limiting hole inside the positioning block 12 to achieve a firm fixation between the bottom mold 9 and the base 5.

[0019] The propulsion assembly 15 is fixed above the slot 14 by a support rod, and the bottom end of the support rod is fixed to the bottom of the slot 14 by screws.

[0020] The propulsion assembly 15 is installed in the middle of the slot 14 of the bottom mold 9 by a support rod (the bottom end is fixed to the bottom of the slot 14 of the bottom mold 9 with screws). The unloading plate 16 is connected to the output end of the propulsion assembly 15 and placed above the bottom mold 9. After the initial assembly of the equipment is completed, the control box 2 at the top of the processing table 1 is used to regulate each electrical workpiece and set the operating parameters.

[0021] Material loading and workstation conveying: The staff member stands in front of the processing table 1 and lays the insoles to be embossed one by one on the mold groove 10 of the bottom mold 9, using the contour of the mold groove 10 to ensure that the insoles are placed in a precise position.

[0022] After the material is loaded, the control box 2 starts the motor 7 below the processing table 1. The gear 8 at the output end of the motor 7 meshes with the gear ring 6 at the bottom of the annular cylinder at the lower end of the base 5. The annular cylinder rotates with the processing table 1 through the bearing, driving the base 5 to rotate synchronously. Multiple ball bearings are rolled at the lower end of the base 5 to contact the upper surface of the processing table 1.

[0023] The ball bearings at the lower end of the base 5 are always in contact with the surface of the processing table 1, providing auxiliary support for the rotation of the base 5 and preventing the base 5 from tilting. Finally, the mold groove 10 containing the insole is accurately delivered to the bottom of the embossing component.

[0024] Insole embossing and shaping: The embossing assembly includes a lifting assembly 3 and a pressure plate 4. The lifting assembly 3 is fixed above the base 5, and the pressure plate 4 is fixed at the output end of the lifting assembly 3.

[0025] When the embossing component is activated, the lifting component 3 drives the pressure plate 4 at its output end to descend vertically. The pressure plate 4 cooperates with the mold groove 10 of the bottom mold 9, and the surface of the insole is formed with the preset pattern of the mold groove 10 through high-frequency hot pressing, thus completing the embossing and shaping.

[0026] After the embossing is completed, the lifting component 3 drives the pressure plate 4 to rise and reset, avoiding interference with the subsequently rotating bottom mold 9.

[0027] Automatic unloading: After the pressure plate 4 is reset, the motor 7 drives the base 5 to rotate again, and the embossed insole is transported along with the bottom mold 9 to the unloading port on one side of the processing table 1.

[0028] At this time, the control box 2 starts the propulsion component 15. The propulsion component 15 drives the unloading plate 16 to move towards the unloading port, pushing the embossed finished product above the mold groove 10 to the outside of the unloading port (which can be received by a pre-set receiving box below the unloading port), thus realizing automatic unloading.

[0029] After a single feeding is completed, the staff can continue to feed materials, forming a continuous cycle of "feeding-embossing-unloading".

[0030] Replacement of sole mold 9 (to accommodate different sizes of insoles): When different specifications of insoles need to be processed, rotate the threaded rod 20 counterclockwise to drive the moving seat 19 down along the threaded rod 20, so that the limiting rod 13 is pulled out from the limiting hole of the positioning block 12, and the bottom mold 9 is released from the fixation; then remove the old bottom mold 9, insert the positioning block 12 of the new bottom mold 9 with the corresponding specification mold groove 10 into the positioning groove 11 of the base 5, rotate the threaded rod 20 clockwise, the moving seat 19 rises, the drive rod 21 pushes the slider 18 to make the limiting rod 13 re-insert into the limiting hole, and the bottom mold 9 replacement is completed.

[0031] Control Chassis 2 Selection: Core functional requirements: As the equipment control center, it needs to realize multi-component collaborative control (motor speed 7, lifting component stroke 3, propulsion component movement 15), human-machine interaction (parameter setting, status display), fault alarm (overload, overtravel protection) and electrical integration (built-in PLC, relay, power module), and adapt to the high-frequency electromagnetic environment of high-frequency equipment and the dust and oil pollution scene in the workshop.
