Description

Technical Field

[0001] This invention belongs to the field of injection molded slipper processing, and specifically discloses an automated edge cutting device for injection molded slipper products. Background Technology

[0002] In the manufacturing process of injection-molded slippers, the sole and upper are often processed separately. After the sole is injection molded, due to factors such as the gap of the mold parting surface, injection pressure and plastic shrinkage, an extra thin sheet of waste material, namely burrs or flash, will inevitably be generated at the edge junction. These burrs not only affect the appearance quality of the product, but their rough edges may also pose a risk of scratching to the user. Therefore, they must be completely removed before leaving the factory.

[0003] The processing of rough edges on injection-molded shoe soles is still mainly done manually. The inconsistency in the shape of the outer edge of the sole further increases the processing difficulty. Currently, operators need to hold the sole by hand, judge the location of the rough edge based on experience, and manually cut it off using tools such as handheld edge cutters, scissors, or cutting blades. This method is not only inefficient and labor-intensive, but the quality of the cut also depends entirely on the operator's skill level. It is very easy to cause problems such as uneven cutting, local residue, or excessive cutting that damages the shoe body due to the complex shape and curvature of the sole edge. This has obvious drawbacks such as poor product quality consistency and high safety hazards. Summary of the Invention

[0009] Preferably, the upper ends of the two electric telescopic rods are connected to movable blocks, and the two movable blocks are connected to the lower parts of both sides of the C-shaped plate. The upper and lower ends of the C-shaped plate are provided with through holes corresponding to the sliding rods. The sliding rods are located inside the two through holes, and the C-shaped plate slides on the outer wall of the sliding rods.

[0010] Preferably, a guide block is connected to the middle of one side of the C-shaped plate, one end of the guide block extends through to one side of the connecting plate, and a guide groove is provided on one side of the connecting plate corresponding to the guide block, and the guide block slides inside the guide groove.

[0011] Preferably, the upper and lower ends of the inner wall of the C-shaped plate are provided with stabilizing grooves, and stabilizing blocks are slidably connected to both sides of the two stabilizing grooves.

Multiple buffer springs are sleeved on the outer walls of multiple arc-shaped rods.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] The device relies on the close linkage of the clamping mechanism, the floating feed mechanism and the trimming mechanism to realize the fully automated operation from loading, clamping, feeding, trimming to unloading. It replaces the traditional manual operation mode of trimming each piece with a hand-held cutter. It not only eliminates the high labor intensity of manual operation, but also greatly shortens the trimming time of a single piece. At the same time, it avoids the efficiency fluctuations caused by fatigue and experience differences in manual operation, significantly improving production efficiency while reducing the company's labor cost input.

[0016] The edge-cutting mechanism employs an adaptive design with a buffer spring and arc-shaped guide, enabling the semi-circular edge-cutting blade to closely follow the complex contours of the shoe sole edge for precise cutting, aided by support and guide rollers. This structure effectively adapts to the undulations of the shoe sole edge, preventing issues such as missed cuts, damage to the workpiece, or uneven edges. This ensures extremely high edge-cutting accuracy and product consistency, significantly reducing subsequent rework and repair costs due to quality problems.

[0017] The height of the cutting mechanism can be easily adjusted via an electric telescopic rod, readily adapting to slipper soles of varying thicknesses. Its adaptive cutting feature also provides excellent tolerance for changes in sole dimensions, reducing the difficulty and time required for production changeovers and enhancing the equipment's versatility and flexible production capabilities.

[0018] The floating feed mechanism provides flexible thrust through floating springs, avoiding damage to the workpiece from rigid collisions. During the trimming process, the support rollers and guide rollers make rolling contact with the workpiece, effectively reducing frictional resistance and cutting vibration. This protects the sole surface from scratches and reduces wear on the trimming blade, extending its service life. Attached Figure Description

[0028] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0029] Numerous specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and therefore the invention is not limited to the specific embodiments disclosed below.

[0030] like Figures 1-8An automated edge-cutting device for injection-molded slipper products is shown, including a base box 1, an upper box body 2 connected to the upper end of the base box 1, partitions 3 connected to the lower parts of both sides of the inner wall of the upper box body 2, floating feed mechanisms connected to both sides of the partitions 3, the two floating feed mechanisms are symmetrically arranged to realize dual-station processing, clamping mechanisms are slidably connected to the upper part of the outer wall of the two floating feed mechanisms, edge-cutting mechanisms are connected to the middle of both sides of the base box 1, and a material collection box 38 is slidably connected to one side of the lower end of the inner wall of the base box 1;

[0031] The floating feed mechanism enables flexible feeding of the clamping mechanism, avoiding rigid collisions between the workpiece and the trimming mechanism; the clamping mechanism fixes the workpiece and drives it to rotate, while the trimming mechanism completes the precise removal of burrs from the shoe sole, replacing manual operation; the collection box 38 facilitates waste cleaning, preventing waste from scattering and polluting the environment; the two workstations can alternately perform loading and unloading and trimming operations, thereby achieving continuous production and effectively improving production efficiency.

[0032] like Figures 1-3 As shown: The floating feed mechanism includes slide rails 4, and there are two sets of slide rails 4. One end of the two slide rails 4 is connected to one side of the partition plate 3, and the other end of the two slide rails 4 is connected to one side of the inner wall of the upper box 2. A movable slider 5 is slidably connected to one side of the outer wall of the two slide rails 4. Floating springs 6 are evenly connected to the middle of one side of the movable slider 5. One end of the multiple floating springs 6 is connected to one side of the partition plate 3. A push block 15 is connected to the middle of one side of the movable slider 5. A second cylinder 14 is connected to the middle of one side of the push block 15. One side of the second cylinder 14 is connected to the lower part of one side of the upper box 2.

[0033] The slide rail 4 ensures that the moving slider 5 slides smoothly. The second cylinder 14 drives the moving slider 5 to slide along the slide rail 4. The elastic deformation of the floating spring 6 achieves flexible feeding, which drives the clamping mechanism and the shoe sole workpiece to move closer or further away from the cutting mechanism, avoiding rigid collision damage to the workpiece.

[0034] like Figure 4 As shown: The clamping mechanism includes a support plate 7, the lower end of which is connected to the upper end of the movable slider 5. The upper end of the support plate 7 is connected to a housing 8. The lower end of the inner wall of the housing 8 is connected to a drive motor 9. The output end of the drive motor 9 extends through to the top of the housing 8. The output end of the drive motor 9 is connected to a placement plate 10. The upper end of the placement plate 10 is connected to a shoe sole workpiece. One side of the upper end of the support plate 7 is connected to an inverted L-shaped plate 11. One side of the upper end of the inverted L-shaped plate 11 is connected to a first cylinder 12. The output end of the first cylinder 12 extends through to the bottom of the inverted L-shaped plate 11. The lower end of the first cylinder 12 is connected to a pressure plate 13. The lower part of the pressure plate 13 contacts the top of the shoe sole workpiece.

[0035] The housing 8 prevents waste from entering the drive motor 9. A silicone anti-slip pad is installed above the placement plate 10 to increase friction with the shoe sole and prevent the workpiece from sliding during rotation. A sponge pad assembly is connected below the pressure plate 13 to prevent scratches on the shoe sole surface. The pressure plate 13 is driven to press down by the first cylinder 12, which works with the placement plate 10 to stably clamp and fix the shoe sole workpiece. Then, the drive motor 9 drives the placement plate 10 and the workpiece to rotate at a uniform speed, providing stable rotation and cutting conditions for the cutting mechanism.

[0036] like Figures 5-8 As shown: The trimming mechanism includes two sets of support blocks 16. One side of each support block 16 is connected to the lower part of one side of the upper housing 2. The upper ends of the two support blocks 16 are connected to support plates 17. One side of the upper end of the support plates 17 is connected to a connecting plate 18. The connecting plate 18 is in the shape of an inverted L-shape. One side of the lower end of the connecting plate 18 is connected to a slide rod 20. A C-shaped plate 23 is slidably connected to the outer wall of the slide rod 20. Guide rollers 28 are rotatably connected to the upper and lower ends of the inner wall of the C-shaped plate 23. A guide plate 19 is connected to one side of the upper end of the support plate 17. One end of the guide plate 19 is connected to the lower part of one side of the connecting plate 18. The lower end of the slide rod 20 is connected to one side of the upper end of the guide plate 19. Electric telescopic rods 21 are evenly connected to one side of the lower end of the support plate 17. The output ends of the two electric telescopic rods 21 pass through the support plate 17 and the guide plate 19 in sequence and extend to the upper end of the guide plate 19. The upper ends of the two electric telescopic rods 21 are connected to the moving blocks 22. The two moving blocks 22 are connected to the lower parts of both sides of the C-shaped plate 23.

[0037] The slide bar 20 ensures the stability of the C-shaped plate 23 sliding up and down. The guide roller 28 is made of polyurethane and is elastic, which ensures that it fits the edge of the shoe sole and avoids scratching the surface of the shoe sole. The rotating structure converts sliding friction into rolling friction. The electric telescopic rod 21 ensures that the height of the C-shaped plate 23 is accurately adjusted to fit shoe soles of different thicknesses. The electric telescopic rod 21 drives the moving block 22 to move the C-shaped plate 23 up and down along the slide bar 20, adjusting the height of the guide roller 28 and the cutting component so that the guide roller 28 can fit the edge of the shoe sole workpiece of different thicknesses, providing stable guidance for the cutting edge.

[0038] Both the upper and lower ends of the C-shaped plate 23 have through holes corresponding to the slide rod 20. The slide rod 20 is located inside the two through holes. The C-shaped plate 23 slides on the outer wall of the slide rod 20. A guide block 24 is connected to the middle of one side of the C-shaped plate 23. One end of the guide block 24 extends through to one side of the connecting plate 18. A guide groove 25 is opened on one side of the connecting plate 18 corresponding to the guide block 24. The guide block 24 slides inside the guide groove 25. Both the upper and lower ends of the inner wall of the C-shaped plate 23 have stabilizing grooves 26. Stabilizing blocks 27 are slidably connected to both sides inside the two stabilizing grooves 26. The lower ends of the two stabilizing blocks 27 and the upper ends of the other two stabilizing blocks 27 are respectively connected to the upper part of one guide roller 28 and the lower end of the other guide roller 28. The two guide rollers 28 are respectively sleeved on the outer wall of the slide rod 20. Stabilizing plates 29 are connected to the upper and lower parts of one side of the C-shaped plate 23. The two stabilizing plates 29 are sleeved on the outer wall of the slide rod 20. The two stabilizing plates 29 are located between the two guide rollers 28.

[0039] The T-shaped structure of the guide block 24 prevents it from coming off the guide groove 25, ensuring that the C-shaped plate 23 moves only in the vertical direction and avoids horizontal deviation. The stabilizing groove 26 and the stabilizing block 27 ensure the stability of the guide roller 28 when it rotates, and at the same time ensure that the guide roller 28 always keeps stable contact with the edge of the workpiece. Meanwhile, the stabilizing plate 29 provides installation support for the subsequent edge cutting components.

[0040] A rotating ring 30 is connected between two stabilizing plates 29. The rotating ring 30 is sleeved on the outer wall of the sliding rod 20. A cutting blade 35 is connected to one side of the rotating ring 30. The cutting blade 35 is semi-arc in shape. A placement groove 36 is opened in the middle of one side of the cutting blade 35. A support roller 37 is embedded in the placement groove 36. Connecting blocks 31 are connected to the lower two sides of one stabilizing plate 29 and the upper two sides of the other stabilizing plate 29. Arc rods 32 are connected to the two sides of two connecting blocks 31 and the two sides of the other two connecting blocks 31. There are four sets of arc rods 32. Buffer blocks 33 are connected to the upper two sides and the lower two sides of the rotating ring 30. Multiple buffer blocks 33 slide on the outer wall of multiple arc rods 32. Buffer springs 34 are connected to the two sides of multiple buffer blocks 33. One end of multiple buffer springs 34 is connected to the two sides of multiple connecting blocks 31. Multiple buffer springs 34 are sleeved on the outer wall of multiple arc rods 32.

[0041] The rotating ring 30 provides an adjustable mounting carrier for the cutting blade 35. Slight rotation around the sliding rod 20 causes the cutting blade 35 to adapt to the irregular contour of the sole edge, avoiding cutting deviation caused by a fixed angle. The cutting blade 35 directly contacts the rough edges of the outer edge of the sole. Its semi-circular structure conforms to the curved shape of the sole edge, ensuring the cutting trajectory matches the sole contour and achieving continuous and complete removal of the rough edges. The placement groove 36 provides mounting space for the support roller 37, ensuring stable mounting and cooperation with the cutting blade 35. The support roller 37 rolls against the sole edge during cutting, converting the sliding friction between the cutting blade 35 and the sole into rolling friction, reducing wear on the sole surface. The connecting block 31 stably connects the arc-shaped rod 32 to the two stabilizing plates. Between 29, a reliable mounting base is provided for the cushioning structure; the arc-shaped rod 32 is used to limit the sliding trajectory of the cushioning block 33, ensuring that the cushioning block 33 moves only along the arc direction that matches the edge of the sole, while providing support for the cushioning spring 34 to prevent it from shifting when the spring deforms; the cushioning block 33 is used to connect the rotating ring 30 and the cushioning spring 34, transferring the force of the rotating ring 30 to the cushioning spring 34, while sliding along the arc-shaped rod 32, driving the rotating ring 30 to achieve adaptive fine adjustment; the cushioning spring 34 absorbs the impact force generated by the irregular edge of the sole due to the irregularity of the rotating ring 30 through its own elastic deformation, on the one hand providing flexible support for the fine adjustment of the rotating ring 30, ensuring that the cutting blade 35 always fits the edge of the sole, and on the other hand avoiding rigid collisions that could damage the cutting blade 35 or the sole, thus improving the stability and safety of the cutting process.

[0042] Working principle: During use, the operator places the injection-molded slipper sole workpiece with flash on the placement plate 10 of the clamping mechanism, and activates the first cylinder 12 on the inverted L-shaped plate 11. The piston rod of the first cylinder 12 extends downward, pushing the pressure plate 13 to move down synchronously until the lower end of the pressure plate 13 is tightly attached to the upper end of the sole workpiece. Through the clamping force between the pressure plate 13 and the placement plate 10, the sole workpiece is firmly pressed onto the placement plate 10, completing the clamping and providing a stable foundation for subsequent rotation and edge cutting.

[0043] Based on the thickness of the sole of the slipper to be processed, the electric telescopic rod 21 of the edge cutting mechanism is activated: if the sole is thick, the output end of the electric telescopic rod 21 moves upward; if the sole is thin, the output end moves downward. Through the driving moving block 22, the entire C-shaped plate 23 connected to it slides up and down along the slide rod 20. During this process, the guide block 24 on one side of the connecting plate 18 slides synchronously in the guide groove 25 to ensure that the C-shaped plate 23 moves without deviation. Finally, the initial height of the upper and lower guide rollers 28 and the semi-circular edge cutting blade 35 is adjusted to align with the edge of the slipper workpiece, preparing for precise edge cutting.

[0044] The piston rod of the second cylinder 14 retracts, causing the push block 15 to move away from the moving slider 5, releasing the constraint on the moving slider 5. The floating spring 6 between the moving slider 5 and the partition 3 rebounds from the compressed state, pushing the moving slider 5 to feed along the two sets of slide rails 4 towards the cutting mechanism until the outer edge of the shoe sole workpiece contacts one side of the two sets of guide rollers 28 and is in contact with the support roller 37 and the cutting edge of the cutting blade 35 in the groove 36 on one side of the cutting blade 35.

[0045] Start the drive motor 9 inside the clamping mechanism housing 8: The output end of the drive motor 9 drives the placement plate 10 and the fixed shoe sole workpiece to rotate at a constant speed. During the rotation, the outer edge of the shoe sole workpiece simultaneously contacts the semi-circular cutting blade 35 of the cutting mechanism and one side of the two sets of guide rollers 28. Due to the friction between the shoe sole edge and the guide rollers 28, the shoe sole will drive the two sets of guide rollers 28 to rotate synchronously when it rotates, which greatly reduces the friction damage to the shoe sole edge and further stabilizes the rotation trajectory of the shoe sole.

[0046] The cutting blade 35 cuts the rough edges of the outer edge of the shoe sole as the sole rotates. If there are local protrusions or depressions on the edge of the sole, the cutting blade 35 and the rotating ring 30 connected to it will move along the direction of the arc rod 32. When there is a protrusion, the rotating ring 30 drives the buffer block 33 to squeeze the buffer spring 34 on one side, and the cutting blade 35 will avoid the protrusion in sync. When there is a depression, the buffer spring 34 on the other side will rebound, pushing the buffer block 33 to drive the cutting blade 35 to follow, ensuring that the cutting blade 35 always fits the outer edge of the sole and achieves adaptive cutting. During the cutting process, the support roller 37 placed in the groove 36 on one side of the cutting blade 35 rolls and contacts the edge of the sole, further reducing the cutting resistance and preventing the edge of the sole from deforming due to cutting force.

[0047] The trimmed scrap falls naturally under gravity and eventually falls into the collection box 38, which is slidably connected to the lower end of the inner wall of the bottom box 1, for easy collection and cleaning later. After the shoe sole workpiece rotates once and the scrap is completely removed, the drive motor 9 is turned off in sequence, and the second cylinder 14 is started to extend its piston rod, which pushes the push block 15 to drive the moving slider 5 and the clamping mechanism to reset along the slide rail 4. Then the first cylinder 12 is started to move its piston rod upward, which drives the pressure plate 13 to detach from the shoe sole workpiece. The operator removes the processed shoe sole, completing one trimming operation, and can enter the processing cycle of the next workpiece.

Those skilled in the art should understand that the present invention is not limited to the above embodiments.
