Description

Technical Field

[0001] This invention relates to the field of shoe sole production technology, and in particular to a production process and equipment for multi-colored shoe soles. Background Technology

[0002] With societal development, people's functional demands for footwear are becoming increasingly diversified, especially regarding the performance requirements of shoe soles. Sports and leisure footwear plays a vital role in people's daily lives. To improve wearing comfort and meet diverse functional needs, sports and leisure shoe soles typically consist of a main body of the sole in different colors and with varying hardness, along with functional components. The main manufacturing process involves pre-setting notches on the sides or bottom of the main body of the sole, with corresponding functional components or decorative pieces positioned there. The hardness ratio and color of these functional components or decorative pieces differ from those of the main body of the sole.

[0003] In existing technologies, most shoe soles require manual removal of the mold after compression molding, which increases manual labor and reduces production efficiency. Summary of the Invention

[0004] In view of the shortcomings of the existing technology, the purpose of this invention is to provide a production process and equipment for multi-colored shoe soles to solve the above problems.

[0005] In view of this, the present invention provides a production process for multi-colored shoe soles, a workbench and a carrier disposed on the workbench, the production process comprising the following steps:

[0006] S1: First, prepare adhesives of different colors;

[0007] S2: Place the prepared adhesive materials of different colors into the dispensing machine respectively;

[0008] S3: The glue injection machine inputs the first base color into the shaping device to shape the bottom, and then the same process is used to shape multiple colors to complete the complete sole;

[0009] S4: Start the rotating device at the bottom of the shaping device to rotate the shaping device. The shaping device pushes the shaped shoe sole onto the cutting and transporting device to cut the edge of the shoe sole flat.

[0010] S5: The operator collects the shoe soles at the output end of the cutting and conveying device and puts them into the warehouse.

[0011] By adopting the above technical solution, through setting S2, the adhesive material can be continuously supplied during the production of shoe soles. Through setting S3, the initial shape of multi-colored shoe soles can be automatically completed, saving manual labor. Through setting S4, the completed initial shoe soles can be automatically cut into finished products, saving manual labor. Through setting S5, it is convenient for operators to collect the finished products.

[0012] In the above technical solution, the dispensing machine further includes:

[0013] Several glue storage tanks are installed on the side wall of the workbench;

[0014] The moving mechanism is mounted on the carrier.

[0015] Several dispensing nozzles are mounted on the moving mechanism;

[0016] Several connecting pipes, one end of which is connected to the output end of the glue storage tank, and the other end of which is connected to the input end of the glue dispensing nozzle;

[0017] The moving mechanism causes the glue nozzle to move up, down, left, and right.

[0018] In this technical solution, by setting up several glue storage tanks, various types of glue can be stored to continuously supply the processing of shoe soles. By setting up a moving mechanism, several glue injection nozzles can be moved to the desired position.

[0019] In the above technical solution, the shaping device further includes:

[0020] The working block includes a shaping block and a rotating block connected to one side of the bottom end of the shaping block. The top of the shaping block and the side facing away from the rotating block are provided with a working hole.

[0021] The mold mechanism extends from the side wall of the plastic block into the working hole;

[0022] The pressing mechanism is located inside the working hole and above the mold mechanism;

[0023] And a first hydraulic cylinder, which is located on the inner side wall of the carrier and whose output end extends toward the working hole and pushes the pressing mechanism to move;

[0024] The rotating block has a rotating groove at its bottom end that is connected to the rotating device. The side wall of the plastic block has a moving hole for the mold mechanism to pass through. The output end of the mold mechanism extends and retracts into the working hole. The side of the plastic block away from the mold mechanism has several spaced injection holes that are connected to the working hole. The side wall of the plastic block has several second hydraulic cylinders. The output end of the second hydraulic cylinder extends through to the inner opening of the injection hole. The output end of the second hydraulic cylinder has a plug that blocks the injection hole.

[0025] In this technical solution, the cooperation between the shaping block and the rotating block enables the rotating device to drive the shaping block to rotate through the rotating block. The cooperation between the mold mechanism and the pressing mechanism enables the pressing of multi-colored shoe soles. The setting of the first hydraulic cylinder enables the pressing mold to be automatically pushed, thereby reducing manual labor. The setting of several spaced glue injection holes enables different colored shoe sole glue to be injected from different inlets, thereby achieving different layers. The cooperation between the second hydraulic cylinder and the plug block can prevent the leakage of glue during extrusion.

[0026] In the above technical solution, the mold mechanism further includes:

[0027] The cover plate is detachable from the molded block and closes to the opening of the movable hole;

[0028] The handle is located on the side of the cover plate away from the molded block;

[0029] The third hydraulic cylinder is mounted on the cover plate and located inside the moving hole;

[0030] The lower template is positioned on the output end of the third hydraulic cylinder;

[0031] And the plug-in block, one end of which is connected to the lower template and the other end is plugged into the inner wall of the working hole;

[0032] The working hole is provided with a plug slot for the plug block to be inserted.

[0033] In this technical solution, the cooperation between the cover plate and the handle facilitates the removal of the third hydraulic cylinder and the lower template, thereby changing the shape of the shoe sole. The third hydraulic cylinder allows the lower template to move into the moving hole, thus pressing out the shoe sole. The insertion block makes the molding process more stable. The cover plate and the molding block can be fixed with screws. The handle and the cover plate are integrally formed. The third hydraulic cylinder and the cover plate are detachably connected, and the lower template and the output end of the third hydraulic cylinder are detachably connected, facilitating the replacement of the lower template.

[0034] In the above technical solution, the further compression molding mechanism includes:

[0035] A fixed block, which has a through hole for the first hydraulic cylinder or the fourth hydraulic cylinder to pass through;

[0036] The connecting rod has one end passing through the fixing block and the other end located above the fixing block;

[0037] The abutment block is fitted onto the connecting rod and is fixedly connected to the top of the fixed block;

[0038] A pressure block is located at the top of the connecting rod;

[0039] An elastic element is fitted onto the connecting rod, and both ends of the elastic element are connected between the contact block and the pressure block, respectively.

[0040] And the pressure template, which is set at the bottom of the connecting rod;

[0041] The top of the inner wall of the carrier is provided with a fourth hydraulic cylinder. When the output end of the fourth hydraulic cylinder extends, it passes through the through hole and pushes the pressing template down. The pressing module and the lower template are pressed together to form the shoe sole.

[0042] In this technical solution, the connecting rod, the contact block, and the pressure block are supported by the fixed block. The cooperation of the connecting rod, the contact block, the pressure block, and the elastic element allows the pressure template to rebound when it is pressed down. The fourth hydraulic cylinder allows the lower template to be continuously pressed down when it retracts, thus pressing it onto the cutting and transporting device for cutting the finished product. The connecting rod and the pressure block are connected by threads, which allows the connection between the connecting rod and the pressure block to be released, thereby disassembling the pressure template and replacing the finished shoe sole.

[0043] In the above technical solution, the further rotating device includes:

[0044] A connecting seat is set on the workbench, and the top of the connecting seat is provided with a movable groove;

[0045] The rotating structure has one end connected to the movable groove and the other end connected to the rotating groove;

[0046] And the drive mechanism, with the fixed end set in the movable slot and the movable end connected to the rotating structure:

[0047] The driving mechanism is used to drive the rotating mechanism to rotate the rotating block, thereby causing the shaping block to rotate.

[0048] In this technical solution, the connecting seat provides support for the rotating mechanism and the driving mechanism. The driving mechanism enables the rotating structure to drive the rotating block and the shaping block to rotate, thereby transferring the initially formed shoe sole to the top of the cutting and transporting device.

[0049] In the above technical solution, the further rotating structure includes:

[0050] Two connecting blocks are provided, with one end of each block being located on the inner wall of the rotating groove on both sides, and the other end being located on the inner wall of the movable groove on both sides. The connecting blocks are rotatably connected to the rotating block and the connecting seat respectively.

[0051] The slide rail has one end set on the inner wall of the rotating groove on the side away from the connecting block, and the other end extends into the movable groove. The slide rail is provided with a sliding groove for the drive mechanism to slide.

[0052] When the drive mechanism moves along the slide groove, the rotating block rotates around the center point where the connecting block and the connecting seat are rotatably connected.

[0053] In this technical solution, the setting of two connecting blocks enables the rotating block to rotate more smoothly. The setting of slide rail and slide groove enables the drive mechanism to run along the direction of the slide groove and push the slide rail to move, so that the rotating block and the shaping block rotate around the center point of the rotational connection between the connecting block and the connecting seat.

[0054] In the above technical solution, the further driving mechanism includes:

[0055] Two support plates are spaced apart between the two connecting blocks, and the two support plates are connected to the bottom of the movable groove;

[0056] The drive motor is mounted on the side wall of one of the support plates, and the output end of the drive motor passes through both support plates.

[0057] A fixed seat is provided at the bottom of the movable groove, and the fixed seat is provided on the bottom of the movable groove on the side away from the support plate;

[0058] The rotating rod is fixedly connected to the output end of the drive motor and is located between the two support plates;

[0059] The movable rod is rotatably connected to the rotating rod;

[0060] A swing arm, on which an eccentric shaft is provided, is rotatably connected to a fixed base via the eccentric shaft;

[0061] And connecting pins, which are connected to the movable rod and the swing rod respectively, and the pins slide in the groove;

[0062] The swing rod and the movable rod are rotatably connected by a connecting pin. The rotating rod, the movable rod, the swing rod and the bottom of the movable groove form a planar four-bar linkage mechanism. When the drive motor starts, the rotating rod and the movable rod drive the connecting pin to move in the slide groove, causing the slide rail to rotate, thereby causing the rotating block to rotate.

[0063] In this technical solution, the drive motor enables the rotating rod to rotate, which in turn moves the connecting pin within the slide groove. The connecting pin prevents the pin from falling off, and the swing arm supports the slide rail. When the connecting pin moves to a corresponding position, the swing arm moves the slide rail to the corresponding position.

[0064] In the above technical solution, the further cutting and conveying device includes:

[0065] A transport platform is set on a workbench, and the transport platform is equipped with a work slot;

[0066] The conveyor belt is installed on the inner wall of the working trough;

[0067] Several hollow shoe sole cutting plates are spaced apart on the conveyor belt;

[0068] An elastic plate is installed inside the conveyor belt, and the elastic plate is located inside the hollow shoe sole cutting plate;

[0069] The module is mounted on the elastic plate;

[0070] The transport platform is located below the fourth hydraulic cylinder. When the third hydraulic cylinder moves the lower template into the moving hole, the output end of the fourth hydraulic cylinder extends and pushes the pressing template to continue to descend, pressing the sole against the hollow sole cutting plate, thereby cutting the excess material at the edge of the sole flat.

[0071] In this technical solution, the conveyor platform allows the conveyor belt to be placed, and the hollow sole cutting plates enable continuous cutting and transport of the initial sole. The elastic plate allows the module to pop out the finished sole, and the module design prevents the initial sole from bending or shifting, thus avoiding cutting misalignment.

[0072] The above technical solution further includes the following steps:

[0073] Step 1: Start the rotating device to rotate the molding block so that the glue injection hole is below the glue injection nozzle;

[0074] Step 2: Retract the second hydraulic cylinder closest to the lower template, causing the plug to move away from the injection hole. Then, the injection nozzle descends and sprays a measured amount of the first color sole. Finally, extend the retracted second hydraulic cylinder to block the injection hole. Step 3: Extend the first hydraulic cylinder, pass through the through hole, and push the pressing template to the corresponding position of the first layer sole color. At this time, the elastic element is compressed. After cooling and molding, retract the first hydraulic cylinder, and the pressing template is rebounded by the elastic element, completing the first color sole.

[0075] Step 4: Similar to Step 2, retract the second hydraulic cylinder that is close to the lower template, inject the second color of the sole, and then perform Step 3 in the same way to press the corresponding position of the second layer of sole color to obtain a two-color sole. Repeat Steps 2, 3 and 4 to obtain a multi-color sole.

[0076] Step 5: Start the rotating device to rotate the shaping block and move it to the top of the transport table. At this time, start the third hydraulic cylinder to retract and move the lower template into the moving hole. Then, start the fourth hydraulic cylinder to extend the output end and press the template through the through hole. The pressing template will press the shoe sole that is stuck on the working hole down to the corresponding hollow shoe sole cutting plate below, thereby cutting off the excess material at the edge of the shoe sole. At the same time, the elastic plate is compressed. After cutting, the fourth hydraulic cylinder retracts and the elastic plate rebounds the shoe sole.

[0077] Step 6: Start the conveyor belt, the operator collects the finished shoe soles, discards the waste, and repeats the above steps to produce the next pair of shoe soles.

[0078] In this technical solution, step 1 facilitates the injection of adhesive into the molding block; step 2 allows the bottom layer of the shoe sole to be filled and sealed with colored molding material; step 3 molds the bottom layer of the shoe sole; step 4 yields multiple colored initial shoe sole shapes; step 5 automatically cuts the multiple colored initial shoe sole shapes into finished products for easy removal; and step 6 allows operators to more easily collect the finished multi-colored shoe soles and waste, enabling continuous automatic production.

[0079] The beneficial effects of this invention are:

[0080] 1. By setting up a shaping device, it is possible to automatically obtain the initial shape of shoe soles in multiple colors;

[0081] 2. By setting up a rotating device, the various colors of shoe sole prototypes produced by the shaping device can be pressed and cut onto the cutting and conveying device to obtain the finished shoe soles that are completely cut;

[0082] 3. By setting up a cutting and conveying device, finished shoe soles of various colors can be obtained by cutting and shaping, and they are easy to pick up and collect. Attached Figure Description

The rotating rod 36, the movable rod 37, the swing rod 38 and the bottom of the movable groove 29 form a planar four-bar linkage. When the drive motor 34 starts, the rotating rod 36 and the movable rod 37 drive the connecting pin 39 to move in the slide groove 32, causing the slide rail 31 to rotate, thereby causing the rotating block 8 to rotate.

[0158] The drive motor 34 enables the rotating rod 36 to drive the movable rod 37 to rotate, and the connecting pin 39 to move within the slide groove 32. The connecting pin 39 prevents it from falling off. The rocker arm 38 supports the slide rail 31, and when the connecting pin 39 moves to the corresponding position, the rocker arm 38 moves the slide rail 31 to the corresponding position.

[0159] Example 9:

[0160] In this embodiment, in addition to the structural features of the aforementioned embodiments, the further comprising the cutting and transporting device includes:

[0165] Module 45 is mounted on the elastic plate 44;

[0166] The transport platform 40 is located below the fourth hydraulic cylinder. When the third hydraulic cylinder 16 moves the lower template 17 into the moving hole, the output end of the fourth hydraulic cylinder 27 extends out and pushes the pressing template 25 to continue to descend, pressing the shoe sole onto the hollow shoe sole cutting plate 43, thereby cutting the excess material at the edge of the shoe sole flat.

[0170] Step 1: Start the rotating device to rotate the molding block so that the glue injection hole 12 is located below the glue injection nozzle 5;

[0171] Step 2: Retract the second hydraulic cylinder closest to the lower template 17 to make the block 13 leave the glue injection hole 12, then the glue injection nozzle 5 descends to spray a fixed amount of the first color of shoe sole, and finally the retracted second hydraulic cylinder extends to make the block 13 block the glue injection hole 12.

[0172] Step 3: Extend the first hydraulic cylinder 10, pass through the through hole 26, and push the pressing template 25 to the corresponding position of the first layer of shoe sole color. At this time, the elastic element 24 is compressed.

Repeat Steps 2, 3 and 4 to obtain a multi-color sole.

[0174] Step 5: Start the rotating device to rotate the shaping block and move it above the transport table 40. At this time, start the third hydraulic cylinder to retract and move the lower template 17 into the moving hole. Then start the fourth hydraulic cylinder to extend the output end and press down the template 25 through the through hole 26. The pressing template 25 presses the shoe sole stuck on the working hole 9 down onto the corresponding hollow shoe sole cutting plate 43 below, thereby cutting off the excess material at the edge of the shoe sole. At the same time, the elastic plate 44 is compressed. After cutting, the fourth hydraulic cylinder 27 retracts and the elastic plate 44 rebounds the shoe sole.
