Description

Technical Field

[0001] This invention relates to the field of footwear processing technology, specifically to a processing equipment for casual shoe soles. Background Technology

[0002] As people's demand for comfort and fashion continues to increase, the footwear manufacturing industry is facing many challenges. The sole is an important part of the shoe. It not only provides support and cushioning, but also needs to have good wear resistance and aesthetics. After the sole is produced by hot pressing, the excess material that overflows from the mold gap due to hot pressing needs to be trimmed off at the outer edge of the sole. This is combined with grinding to make the connection and transition between the sole and the upper smoother and more beautiful.

[0003] The invention patent with publication number CN117223941A discloses a shoe sole trimming device and its usage method, including a base, a support plate provided on the rear side of the upper end of the base, a moving mechanism provided on the upper end of the front of the support plate, a grinding component provided on the lower end of the moving mechanism, the grinding component being driven by the moving mechanism to perform left and right reciprocating motion, and a fixing mechanism provided on both sides of the front of the support plate, the fixing mechanism being used to fix the two ends of the shoe sole.

[0004] In the aforementioned patent, the sole trimming device uses a fixing mechanism to secure the sole, followed by a moving mechanism that drives a grinding mechanism to directly grind the outer contour of the sole. When the area of ​​the burr on the sole is large, it is necessary to pre-trim the burr at other workstations before grinding. Grinding directly without trimming would increase the grinding load and even affect the grinding effect. Therefore, it lacks proper handling of large burr areas, affecting processing efficiency and quality. The fixing mechanism uses two sets of circumferentially distributed fixing rods to press and fix the edge of the sole. This causes the grinding rod to obstruct the grinding along the outer contour of the sole. Furthermore, since the grinding rod is elastically connected to both sides of the bottom of the moving mechanism, it is impossible to grind the front and back ends of the sole, resulting in incomplete grinding. In addition, the grinding rod uses elasticity to adaptively conform to the outer contour of the sole during grinding, which makes it difficult to control the grinding pressure. The grinding pressure varies greatly in different areas, resulting in poor grinding quality. Summary of the Invention

[0005] The purpose of this invention is to address the problems of low overall processing efficiency, incomplete grinding, and poor quality of general shoe sole processing equipment. This invention provides a casual shoe sole processing equipment.

[0006] To achieve the above objectives, the present invention specifically adopts the following technical solution:

[0007] A casual shoe sole processing device includes a waste material tray and a shoe support fixedly connected to the center of the waste material tray. A platform with a processing groove in the middle and driving grooves on both sides is fixedly connected to the top of the waste material tray. L-shaped and diagonally arranged screw blocks are slidably engaged in the driving grooves on both sides. Telescopic arms are slidably engaged in the screw blocks. A hollow grinding shaft is rotatably connected to the side of the telescopic arm near the processing groove. The outer walls of the upper and lower sides of the grinding shaft are provided with circumferentially arrayed suction holes. A grinding sleeve is fixedly sleeved in the middle of the outer periphery of the grinding shaft. A control component is provided on the platform to drive the grinding sleeve to rotate and grind along the outer contour of the shoe sole. A positioning component for surrounding the shoe support is provided at the bottom of the platform.

[0008] A suspension is fixedly connected to the top of the platform, and a multi-stage telescopic cylinder is installed on the suspension. An inverted T-shaped elastic pressure plate is slidably engaged with the inner wall of the telescopic end of the bottom of the telescopic cylinder. A ring blade is fixedly connected to the periphery of the telescopic end of the telescopic cylinder, and wing blades are fixedly connected around the ring blade.

[0009] Furthermore, the waste tray has openings on both the left and right sides, and the shoe tray is T-shaped and located at the bottom of the processing groove.

[0010] Furthermore, the control component includes screws rotatably connected in drive slots on both sides, with the threads on the two screws having opposite directions, and a synchronous belt movably sleeved between the front ends of the two screws. The screw on the left side is driven by a forward and reverse motor mounted on the rear wall of the platform, and the screws on both sides are threadedly inserted into corresponding screw blocks.

[0011] Furthermore, the control assembly also includes a vertical bevel gear and a longitudinal bevel gear rotatably connected to the upper and lower sides of the screw block sidewall, respectively. The vertical bevel gear and the longitudinal bevel gear are meshed together. The longitudinal bevel gear is movably sleeved on the screw. The longitudinal bevel gear and the screw have key protrusions and keyways that engage with each other. A belt roller is rotatably connected to the upper end of the telescopic arm on the side away from the grinding shaft. A transmission belt is movably sleeved between the vertical bevel gear, the belt roller, and the top of the grinding shaft. A guide roller that is movably sleeved on the side of the screw block sidewall near the vertical bevel gear is rotatably connected to the side of the screw block sidewall near the vertical bevel gear.

[0012] Furthermore, an L-shaped air guide block is fixedly connected to the upper end of the telescopic arm near the processing groove. The air guide block has an air guide groove that is rotatably and sealingly connected to and communicates with the top of the grinding shaft. A hose is fixedly connected between the upper end of the air guide groove and the upper wall edge of the corresponding side of the suspension. The hose is externally connected to a negative pressure dust extraction mechanism.

[0013] Furthermore, the control component also includes guide grooves on the left and right sides of the platform. The guide grooves are composed of short straight grooves on the front and rear sides and an arc groove in the middle. The trajectory of the arc groove matches the outer contour of the shoe sole to be processed. The telescopic arm is fixedly connected to a pin that slides and engages with the guide grooves on the side away from the processing groove.

[0014] Furthermore, the positioning component includes a locking plate that is slidably engaged with the left and right sides of the lower wall of the platform, and the locking plate is provided with a guide groove that is slidably engaged with the pin. Two inclined rods are fixedly connected to the lower wall of the locking plate, and a locking frame that is movably engaged with the shoe support is fixedly connected between the two inclined rods.

[0015] The second guide groove is composed of inclined grooves on the front and rear sides in opposite directions and a long straight groove in the middle. The intersection points of the short straight grooves and arc grooves on the front and rear sides of the first guide groove are respectively located inside the intersection points of the inclined grooves and long straight grooves on the front and rear sides.

[0016] Furthermore, the ring blade corresponds vertically to the edges of the two card frames, the wing blade is located above the inclined rod fixedly connected to the lower wall of the card plate, and the upper ends of the inclined rod have chamfered edges on both sides.

[0017] Furthermore, a multi-stage telescopic rod is fixedly connected between the lower wall of the suspension and the elastic pressure plate, and a protective frame located around the periphery of the ring blade is fixedly connected to the lower wall of the suspension.

[0018] The beneficial effects of this invention are as follows:

[0019] 1. This invention utilizes a shoe support and positioning component to install and limit the sole. After the extension of the telescopic cylinder drives the elastic pressure plate to move downward and press and fix the sole, the extension of the telescopic cylinder can drive the ring blade and wing blade to cut the burr on the outer edge of the sole. After the burr is removed, the extension cylinder drives the ring blade to move upward while the elastic pressure plate continues to press against the sole. With the help of the operation control component, the enclosure component automatically removes its enclosure of the sole first, and the grinding sleeve then grinds the outer edge of the sole. This integrates the trimming and grinding processes, improving the processing efficiency of the sole.

[0020] 2. When the control component drives the screw blocks on both sides to move in opposite directions, the telescopic arms on both sides automatically drive the grinding shaft so that the grinding sleeve rotates synchronously in opposite directions along both sides of the outer contour of the shoe sole for grinding. The grinding completely covers the outer contour of the shoe sole, and the pressure is controllable. During the grinding, the grinding shaft rotates automatically and uses the suction hole to suck up the grinding area to remove grinding dust. The grinding is safe and reliable, and the grinding effect is good and of high quality. Attached Figure Description

[0031] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0032] Example 1, as Figures 1-9 As shown, a casual shoe sole processing equipment includes a waste material tray 1 and a shoe tray 11 fixedly connected to the center of the waste material tray 1. The waste material tray 1 has openings on both the left and right sides. The shoe tray 11 is T-shaped and located at the bottom of the processing groove. A platform 2 with a processing groove in the middle and driving grooves on both sides is fixedly connected to the top of the waste material tray 1. L-shaped screw blocks 3 are slidably engaged in the driving grooves on both sides. Telescopic arms 31 are slidably engaged in the screw blocks 3. A hollow grinding shaft 41 is rotatably connected to the side of the telescopic arm 31 near the processing groove. The upper and lower outer walls of the grinding shaft 41 are provided with circumferentially arrayed suction holes 42. A grinding sleeve 43 is fixedly sleeved in the middle of the outer periphery of the grinding shaft 41. A control component is provided on the platform 2 to drive the grinding sleeve 43 to rotate and grind along the outer contour of the shoe sole. A positioning component is provided at the bottom of the platform 2 to surround the shoe tray 11.

[0033] A suspension 6 is fixedly connected to the top of the platform 2. A multi-stage telescopic cylinder 61 is installed on the suspension 6. An inverted T-shaped elastic pressure plate 62 is slidably engaged with the inner wall of the telescopic end of the bottom of the telescopic cylinder 61. A ring blade 63 is fixedly connected to the periphery of the telescopic end of the telescopic cylinder 61. A wing blade 64 is fixedly connected around the ring blade 63.

[0034] In use, the positioning component surrounds the shoe base 11, and the shoe sole with the burr is placed on the shoe base 11. The positioning component automatically limits the position of the shoe sole, and the burr at the edge of the shoe sole is exposed. Initially, the elastic pressure plate 62 is in a compressed state with a large elastic force. The multi-stage telescopic cylinder 61 extends, causing the elastic pressure plate 62 and the ring blade 63 to move downward synchronously. The elastic pressure plate 62 first contacts the shoe sole and presses and fixes the shoe sole. Subsequently, as the telescopic cylinder 61 extends further, the elastic pressure plate 62 cannot move further downward and moves relative to the telescopic end of the telescopic cylinder 61. As the wall moves upward, the elastic pressure plate 62 is further compressed, while the telescopic cylinder 61's telescopic end drives the ring blade 63 downward to punch and cut the flash on the edge of the sole. The wing blade 64 then separates the punched flash, allowing it to be segmented and fed into the waste tray 1 when a full circle or a long flash exists. This effectively removes flash. Subsequently, the telescopic cylinder 61 is partially reset, ensuring the elastic pressure plate 62 remains pressed and fixed against the sole, while the ring blade 63 moves upward, thus not affecting subsequent sole contour grinding operations. The subsequent control is achieved through the control components. The screw blocks 3 on both sides drive the telescopic arms 31 to move in opposite directions. The telescopic arms 31 drive the grinding shaft 41 so that the grinding sleeves 43 approach and abut against the front and rear ends of the sole respectively. When the grinding sleeves 43 begin to grind the outer contour of the sole, the positioning component first removes the enclosure of the shoe support 11, thereby exposing the outer contour of the sole. Under the drive of the control component, when the grinding sleeves 43 abut against the outer contour of the sole, they simultaneously rotate in opposite directions along both sides of the outer contour to grind. That is, the left grinding sleeve 43 grinds from the front end of the sole along the outer contour to the rear end of the sole, while the right grinding sleeve... 43 The grinding process starts from the rear end of the sole and proceeds along the outer contour to the front end, completely covering the outer contour of the sole. The pressure is controllable, ensuring safe and reliable grinding with good and high-quality results. During grinding, the grinding shaft 41 automatically rotates and sucks up the dust from the grinding sleeve 43 through the suction holes 42 on its upper and lower sides, thereby reducing dust pollution to the equipment and the environment. In addition, the trimming and grinding processes are integrated into one machine, improving the processing efficiency of the sole. After grinding is completed, the telescopic cylinder 61 is reset to remove the processed sole.

[0035] In embodiment two, based on the above embodiment, the control component includes screws 22 rotatably connected in the drive slots on both sides, the threads on the two screws 22 are in opposite directions, a synchronous belt is movably sleeved between the front ends of the two screws 22, the left screw 22 is driven by a forward and reverse motor installed on the rear wall of the platform 2, and the two screws 22 are respectively threaded into the corresponding screw blocks 3.

[0036] The left screw 22 is rotated by the forward and reverse motors, and the left screw 22 in turn rotates in the same direction by the right screw 22 via the synchronous belt. Since the threads on the two screws 22 are set in opposite directions, the screw blocks 3 on both sides move in opposite directions, respectively driving the grinding sleeve 43 to grind along the outer contour of the sole. After one grinding is completed, the forward and reverse motors can be controlled to reverse, driving the grinding sleeve 43 to continue to grind the sole.

[0037] In embodiment three, based on the above embodiments, the control component further includes a vertical bevel gear 33 and a longitudinal bevel gear 34 rotatably connected to the upper and lower sides of the sidewall of the screw block 3, respectively. The vertical bevel gear 33 and the longitudinal bevel gear 34 are meshed together. The longitudinal bevel gear 34 is movably sleeved on the screw 22. The longitudinal bevel gear 34 and the screw 22 have key protrusions and keyways that are mutually engaged. A belt roller 36 is rotatably connected to the upper end of the telescopic arm 31 on the side away from the grinding shaft 41. A transmission belt is movably sleeved between the vertical bevel gear 33, the belt roller 36 and the top end of the grinding shaft 41. A guide roller 35, which is movably sleeved on the sidewall of the screw block 3 near the vertical bevel gear 33, is rotatably connected to the sidewall of the screw block 3. The guide roller 35 is used to increase the contact area between the transmission belt and the vertical bevel gear 33.

[0038] When the screw 22 rotates, it drives the longitudinal bevel gear 34 to rotate synchronously. The longitudinal bevel gear 34 meshes and drives the vertical bevel gear 33 to rotate. The vertical bevel gear 33 drives the grinding shaft 41 through the transmission belt, causing the grinding sleeve 43 to rotate. With the design of the belt roller 36 and guide roller 35, the transmission belt still drives stably when the telescopic arm 31 extends and retracts. There is no need to configure an additional grinding drive motor. The grinding sleeve 43 rotates and grinds stably and reliably, and does not affect the rotation and suction of dust by the grinding shaft 41.

[0039] In embodiment four, based on the above embodiment, an L-shaped air guide block 4 is fixedly connected to the upper end of the telescopic arm 31 near the processing groove. The air guide block 4 has an air guide groove that is rotatably and sealingly connected to the top of the grinding shaft 41 and communicates with it. A hose 44 is fixedly connected between the upper end of the air guide groove and the upper wall edge of the corresponding side of the suspension 6. The hose 44 is externally connected to a negative pressure dust extraction mechanism.

[0040] With this design, when processing the sole, the hose 44 is connected to an external negative pressure dust extraction mechanism. When the grinding shaft 41 is driven by the telescopic arm 31 to move back and forth along the outer contour of the sole and the dust is sucked into the interior by the suction hole 42, the dust can be discharged to the external negative pressure dust extraction mechanism through the air guide groove on the air guide block 4 and the hose 44. The design of the hose 44 being fixedly connected to the upper edge of the corresponding side of the suspension 6 ensures that the hose 44 automatically avoids the ring blade 63 when it moves.

[0041] In embodiment five, based on the above embodiments, the control component further includes guide grooves 21 on the left and right sides of the platform 2. The guide grooves 21 are composed of short straight grooves on the front and rear sides and an arc groove in the middle. The trajectory of the arc groove matches the outer contour of the shoe sole to be processed. The telescopic arm 31 is fixedly connected to a pin 32 that slides and engages with the guide grooves 21 on the side away from the processing groove.

[0042] Initially, the left telescopic arm 31 drives the pin 32 to slide and engage with the front end of the guide groove 21, while the right telescopic arm 31 drives the pin 32 to slide and engage with the rear end of the guide groove 21. This ensures that when the screw blocks 3 on both sides drive the telescopic arms 31 to move in opposite directions, the corresponding grinding sleeve 43 can first abut against the front and rear ends of the sole. Under the guidance of the subsequent arc groove on the pin 32, the grinding sleeve 43 can move stably along the outer contour of the sole, the grinding pressure is controllable, and the grinding pressure is relatively consistent in all places, resulting in a good grinding effect.

[0043] In embodiment six, based on the above embodiments, the positioning component includes a locking plate 5 that is slidably locked onto the left and right sides of the lower wall of the platform 2. The locking plate 5 has a guide groove 51 that is slidably locked onto the pin 32. Two inclined rods are fixedly connected to the lower wall of the locking plate 5, and a locking frame 52 that is movably locked onto the shoe support 11 is fixedly connected between the two inclined rods.

[0044] Guide groove 251 is composed of inclined grooves on the front and rear sides in opposite directions and a long straight groove in the middle. The intersection points of the short straight grooves and arc grooves on the front and rear sides of guide groove 121 are respectively located inside the intersection points of the inclined grooves and long straight grooves on the front and rear sides.

[0045] Initially, the left pin 32 is engaged at the front end of the guide groove 2 51, while the right pin 32 is engaged at the rear end of the guide groove 2 51. When the screw blocks 3 on both sides drive the telescopic arms 31 to move in opposite directions, and the left and right pins 32 are just engaged in the long straight groove from the inclined groove in the guide groove 2 51, the pins 32 have not yet been engaged in the arc groove from the short straight groove in the guide groove 1 21. This ensures that before grinding, the pins 32 can first squeeze the inclined groove to drive the clamping plates 5 on both sides to separate the clamping frame 52 from the shoe support 11, so as to expose the outer contour of the shoe sole in time for subsequent grinding.

[0046] In embodiment seven, based on the above embodiment, the ring blade 63 corresponds vertically to the edges of the two card frames 52, the wing blade 64 is located above the inclined rod fixedly connected to the lower wall of the card plate 5, and the upper ends of the inclined rod are chamfered on both sides.

[0047] With this design, after the sole is placed on the shoe support 11 and between the two clip frames 52, the burr of the sole overlaps the top edge of the clip frame 52. Subsequently, the control ring blade 63 moves down to cut the burr, and the wing blade 64 is used to cut the cut burr into segments, and to prevent the cut burr segments from falling and getting caught on the connecting rod, thus affecting the subsequent burr cutting operation.

[0048] In embodiment eight, based on the above embodiments, a multi-stage telescopic rod 65 is fixedly connected between the lower wall of the suspension 6 and the elastic pressure plate 62, and a protective frame 66 located around the ring blade 63 is fixedly connected to the lower wall of the suspension 6.

[0049] With the multi-stage telescopic rod 65, after the telescopic cylinder 61 extends and drives the elastic pressure plate 62 to press and fix the sole of the shoe and reach the calibrated pressure, the telescopic rod 65 just extends to its maximum length, thereby limiting the downward movement of the elastic pressure plate 62. Subsequently, the telescopic cylinder 61 is further extended to compress the elastic pressure plate 62 and drive the ring blade 63 to move down to punch and cut, which can prevent the elastic pressure plate 62 from continuing to move down and excessively squeezing the sole of the shoe, causing damage to the sole. After the ring blade 63 punches and cuts the flash, the telescopic cylinder 61 is partially reset, so that the ring blade 63 returns to the upper part of the outer contour of the sole, while the telescopic rod 65 still maintains its maximum length so that the elastic pressure plate 62 presses and fixes the sole of the shoe, thus not affecting the subsequent grinding operation.

[0050] The design of the protective frame 66 ensures that the ring blade 63 is inside the protective frame 66, preventing accidental human contact and injury when the shoe sole is placed, thus improving the safety performance of the process.

[0051] The above description of the disclosed embodiments enables those skilled in the art to make or use the invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the invention. Therefore, the invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
