Description

Technical Field

[0001] This utility model belongs to the field of shoe sole pressing technology, and in particular relates to a shoe sole pressing and rolling edge device. Background Technology

[0002] The sole of a shoe includes all the materials that make up the bottom, such as the outsole, midsole, and heel. There are many types of sole materials, which can be divided into natural and synthetic materials. Natural sole materials include natural leather, bamboo, and wood, while synthetic sole materials include rubber, plastics, rubber-plastic composites, recycled leather, and flexible cardboard. Modern shoe soles are generally multi-layered. During shoe production, a pressing device is used to press the glued sole together. Simultaneously, a manual edge-rolling process is required, where the edges of the sole are pressed individually after bonding to ensure the overall adhesion and fixation of the sole.

[0003] Patent application CN202022323581.6 discloses a shoe sole pressing device, including an upper platform and a lower platform. The upper platform is provided with an upper mold and a cylinder for driving the upper mold to move up and down. The lower platform is provided with multiple lower molds for placing shoe soles. The lower molds have limiting grooves for placing shoe soles. The upper mold is provided with a pressure plate that inserts and cooperates with the limiting grooves. A frustum is vertically rotatably connected to the upper end face of the lower platform. Multiple lower molds are circumferentially distributed on the outer circumference of the frustum. A limiting member for limiting the rotation of the frustum is slidably connected to the lower platform. When the lower mold rotates to abut against the limiting member, the limiting groove is directly opposite the pressure plate. This application has the effect of reducing the time waiting for workers to load and unload materials in the pressing machine, and improving the working efficiency of the pressing machine.

[0004] In the aforementioned technology, the rotation of the truncated cone allows the upper mold and multiple lower molds to sequentially press the shoe sole together, keeping the pressing device constantly operational. This reduces the time the pressing machine spends waiting for workers to load and unload materials, thus improving the machine's efficiency. However, some shortcomings still exist in its overall operation:

[0005] First, the force applied to the sole edges during the pressing process is insufficient to achieve the required adhesion. The sole edges are also prone to lifting due to uneven stress. Furthermore, there is no equipment provided for the edge-rolling process. In existing technologies, pressing and edge-rolling are typically separate processes requiring two independent machines. This not only increases the number of steps in the sole bonding process and affects processing efficiency, but also results in the adhesive on the sole edges not being firmly bonded over time, leading to a weaker bond than during pressing. Additionally, edge-rolling requires manual handling, where the shoe is rolled around the outer circumference of the sole on the rolling device, impacting efficiency, increasing labor intensity, and posing a risk of injury from being pinched. Utility Model Content

[0006] To overcome the shortcomings of existing technologies, this invention provides a shoe sole pressing and rolling edge device. This invention uses a pressing mechanism to press the shoe sole, and a rolling edge assembly to roll and press the edge of the sole. Simultaneously, during this process, a driving rotating component synchronously rotates the processing table and the pressing mechanism, and a first driving component drives the first support frame to move towards the rolling edge assembly. This ensures that the rolling edge assembly remains in contact with the edge of the sole, resulting in better rolling and pressing of the sole and effectively improving the bonding quality. Furthermore, the linkage of the above structures eliminates the need for separate pressing and rolling processes, allowing them to be performed simultaneously on a single machine, effectively improving the bonding efficiency of the shoe sole. It also eliminates the need for manual rotation of the shoe, effectively reducing labor intensity and improving the safety of the rolling process.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a shoe sole pressing and rolling device, comprising a frame, a first support frame on the frame, a processing table and a pressing mechanism rotatably mounted on one side of the first support frame, the processing table and the pressing mechanism rotating synchronously with their rotation axes vertically arranged, and the pressing mechanism being used to press the shoe sole on the processing table, a second support frame on the frame, and a rolling assembly on the second support frame, the first support frame moving along one side of the rolling assembly via a first driving member, the rolling assembly including a connecting plate mounted on the second support frame, two vertically symmetrical rolling shafts rotatably mounted on the connecting plate, and a gap groove between the two rolling shafts that mates with the edge of the shoe sole.

[0008] Optionally, the rolling assembly also includes a first cylinder mounted on a second support frame. A push plate is fixedly connected to the output end of the first cylinder, and a connecting plate is fixedly mounted on the push plate. A first guide rod is symmetrically mounted on the second support frame. One end of the first guide rod passes through the push plate, and the push plate and the first guide rod slide together.

[0009] Optionally, the processing table and the pressing mechanism are respectively mounted on the first support frame via two rotating components. The rotating components include a motor mounted on the first support frame, the output end of the motor passing through the first support frame and connected to a rotating disk, and the processing table and the pressing mechanism are respectively fixed on the two rotating disks.

[0010] Optionally, the bottom of the rotating disk is provided with several limiting rods, the first support frame is provided with a limiting groove, one end of the limiting rod is inserted into the limiting groove and rotates with the limiting groove, and an anti-detachment block is provided on the end of the limiting rod inserted into the limiting groove.

[0011] Optionally, the pressing mechanism includes a second cylinder mounted on a rotating disk, the output end of which passes through the rotating disk and is connected to a pressure plate.

[0012] Optionally, the first driving component includes a fixed plate mounted on the frame, a third cylinder mounted on the fixed plate, the output end of the third cylinder passing through the fixed plate and connected to the first support frame, and a second guide rod fixedly mounted on the frame, one end of the second guide rod passing through the first support frame, and the first support frame and the second guide rod slidingly engaged.

[0013] Optionally, the processing table is equipped with an upwardly protruding positioning plate, which is a plate structure that runs vertically through the body. The positioning plate is used to position and fix the shoe sole.

[0014] Optionally, the processing table has a receiving cavity, the positioning plate is slidably located in the receiving cavity, and the processing table is provided with a positioning component for fixing the positioning plate so that the positioning plate protrudes onto the processing table.

[0015] Optionally, the positioning component includes a fourth cylinder installed in the machining table, a drive plate on the output end of the fourth cylinder, a transmission wheel connected to the drive plate in the machining table, the transmission wheel rotating in the machining table, a lifting plate connected to the transmission wheel in the machining table, and a support plate for abutting the positioning plate in the machining table, one end of the support plate slidingly engaging with the lifting plate.

[0016] Optionally, one end of the lifting plate has a first inclined surface. The support plate has a second inclined surface that cooperates with the first inclined surface.

[0017] In summary, compared with existing technologies, the beneficial effects of this solution are as follows:

[0018] (1) The sole is pressed by the pressing mechanism, and the edge rolling assembly rolls and presses the edge of the sole. During this process, the processing table and the pressing mechanism are rotated synchronously by the driving rotating assembly, and the first driving component drives the first support frame to move toward the edge rolling assembly, so that the edge rolling assembly always keeps in contact with the edge of the sole, thereby better rolling and pressing the sole and effectively improving the bonding quality of the sole. At the same time, through the linkage of the above structure, the pressing and edge rolling do not need to be divided into two processes, but can be carried out simultaneously on one machine, effectively improving the bonding efficiency of the sole, and eliminating the need for manual rotation of the shoe, effectively reducing the labor intensity and improving the safety of edge rolling;

[0019] (2) Using the edge rolling beads to roll the edge of the shoe sole, on the one hand, the edge rolling effect of the shoe sole is improved, and on the other hand, the edge of the shoe sole and the edge rolling shaft are rolled friction during the rotation of the shoe sole with the processing table, which ensures the stability of the shoe sole during the edge rolling process, thereby ensuring the edge rolling and pressing quality of the shoe sole.

[0020] (3) Use an electric heating rod to heat the rolling roller, so that heat is transferred to the edge of the shoe sole during the rolling process, and the glue on the edge of the shoe sole is heated to a certain extent.

[0021] (4) Under the action of the first and second inclined surfaces, the support plate moves to the outside of the third groove and abuts against the positioning plate, thereby fixing the positioning plate outside the receiving cavity, making the height of the positioning plate greater than the height of the processing table, and then placing the shoe sole inside the positioning plate, thereby fixing and positioning the shoe sole.

[0030] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0031] refer to Figure 1-7 A shoe sole pressing and edge-rolling device includes a frame 1, a first support frame 2 on the frame 1, a first horizontal plate 3 and a second horizontal plate 4 on one side of the first support frame 2, the first horizontal plate 3 and the second horizontal plate 4 being arranged parallel to each other, a processing table 5 rotatably mounted on the first horizontal plate 3, and a pressing mechanism rotatably mounted on the second horizontal plate 4. The processing table 5 and the pressing mechanism are respectively mounted on the first horizontal plate 3 and the second horizontal plate 4 via two rotating components, so that the processing table 5 and the pressing mechanism can rotate synchronously and their rotation axes are vertically arranged. A second support frame 6 is fixedly mounted on the frame 1, and an edge-rolling component is mounted on the second support frame 6. The first support frame 2 moves along one side of the edge-rolling component via a first driving member. The shoe sole is placed on the processing table 5, the pressing mechanism presses the shoe sole, and the edge-rolling component rolls and presses the edge of the shoe sole. Because the sole has an irregular structure, during this process, the rotating drive assembly synchronously rotates the processing table 5 and the pressing mechanism, allowing the sole to rotate circumferentially. Then, the first drive component drives the first support frame 2 to adjust its position towards the edge-rolling assembly according to the sole's contour, ensuring the edge-rolling assembly remains in contact with the sole edge for better edge-rolling and pressing, thus improving the bonding quality. To ensure the edge-rolling assembly always moves outside the sole contour, the size data of each batch of shoes to be pressed is input into the controller 42 before the equipment starts. The controller 42, in conjunction with corresponding sensors, controls the movement of the pressing mechanism and the edge-rolling assembly. The control principle is existing technology and will not be elaborated upon here. Through the linkage of the above structures, pressing and edge-rolling can be performed simultaneously on one machine, effectively improving the bonding efficiency of the sole. Furthermore, it eliminates the need for manual shoe rotation, reducing labor intensity and improving the safety of the edge-rolling process.

[0032] refer to Figure 1-2The hemming assembly includes a first cylinder 7 mounted on a second support frame 6. A push plate 8 is mounted on the output end of the first cylinder 7, and a connecting plate 9 is fixedly mounted on the push plate 8. Two symmetrically positioned hemming shafts 10 rotate on the connecting plate 9, with a gap groove 11 between the two hemming shafts 10 that mates with the edge of the shoe sole. The first cylinder 7 drives the push plate 8 to move, adjusting the distance between the hemming shafts 10 and the shoe sole, allowing the hemming shafts 10 to accurately move to the edge of the shoe sole for hemming and pressing. Specifically, the connecting plate 9 has a slot, within which both hemming shafts 10 rotate. A rotary motor is mounted on one end of each hemming shaft 10, driving the two hemming shafts 10 to rotate. The rotary motor is existing technology and will not be described in detail. The lower hemming shaft 10 is fixed in the groove by bearings, and the upper hemming shaft 10 is slidably in the groove by bearings. The connecting plate 9 is equipped with an electric push rod, the output end of which is connected to the upper hemming shaft 10. The length of the gap groove 11 between the two hemming shafts 10 can be adjusted by the electric push rod, so as to adapt to shoe soles of different thicknesses and facilitate hemming the shoe sole.

[0033] The push plate 8 passes through the first guide rod 12, and the push plate 8 and the first guide rod 12 are slidably engaged. The two ends of the first guide rod 12 are respectively fixed to the second support frame 6. This improves the stability of the movement of the push plate 8 and the connecting plate 9, ensuring that the sole can accurately enter the gap groove 11, so that the edge rolling shaft 10 can press the sole edge together.

[0034] A plurality of edge-rolling beads 13 are provided on the side of the edge-rolling shaft 10 near the sole. The edge-rolling beads 13 protrude from the outer surface of the edge-rolling shaft 10 and are evenly distributed along the circumference of the edge-rolling shaft 10. By using the edge-rolling beads 13 to roll the edge of the sole, the edge-rolling effect of the sole is improved, and the rolling friction between the edge of the sole and the edge-rolling shaft 10 is ensured during the rotation of the processing table 5. This prevents the edge of the sole from getting stuck in the gap groove 11 and unable to rotate, or even causing the shoe to shift on the processing table 5, thus ensuring the stability of the sole during the edge-rolling process and ensuring the quality of the edge-rolling and pressing of the sole.

[0035] To further improve the edge-sealing effect of the sole, a heating chamber coaxial with the two edge-sealing shafts 10 is provided. An electric heating rod is installed along the length of each heating chamber, heating the edge-sealing shaft 10. This heat is transferred to the sole edge during the edge-sealing process, heating the adhesive on the sole edge to a certain extent. Simultaneously, the temperature around the edge of the sole being sealed is relatively high, which is beneficial for adhesive coagulation, thereby improving the sealing quality of the sole. To ensure heat transfer, the edge-sealing beads 13 are made of a thermally conductive material, such as copper-aluminum alloy. This allows the heat generated by the electric heating rod to be transferred to the sole edge at any time, resulting in good heat transfer and avoiding heat waste.

[0036] refer to Figure 4-5 The rotating assembly includes two motors 14 mounted on the first horizontal plate 3 or the second horizontal plate 4. The output end of the motor 14 passes through the first horizontal plate 3 or the second horizontal plate 4 and is connected to a rotating disk 15. The processing table 5 is fixedly mounted on one of the rotating disks 15. Specifically, the bottom of the rotating disk 15 is provided with several evenly distributed limiting rods 16. The first horizontal plate 3 and the second horizontal plate 4 both have limiting grooves 17 that cooperate with the limiting rods 16. The limiting rods 16 and the limiting grooves 17 are rotatably engaged. One end of the limiting rod 16 has a "T" structure, or the end of the limiting plate inserted into the limiting groove 17 has an anti-detachment block 18. Under the action of the limiting rods 16, the rotational stability of the rotating disk 15 is improved, thereby ensuring the stability of the shoe sole during pressing.

[0037] The pressing mechanism includes a second cylinder 19 fixedly mounted on the rotating disk 15. The output end of the second cylinder 19 passes through the rotating disk 15 and is connected to a pressure plate 20.

[0038] The first driving component includes a fixed plate 21 fixedly mounted on the frame 1. A third cylinder 22 is mounted on the fixed plate 21. The output end of the third cylinder 22 passes through the fixed plate 21 and is connected to the first support frame 2. A second guide rod 23 is slidably mounted through the first support frame 2, and both ends of the second guide rod 23 are fixedly mounted on the frame 1. The third cylinder 22 drives the first support frame 2 to move, thereby moving towards the edge rolling assembly, so that the edge rolling shaft 10 can always maintain contact with the edge of the sole, ensuring that the edge rolling shaft 10 presses the sole together.

[0039] refer to Figure 4 , 6 -7. A positioning plate 24 protrudes upward from the processing table 5. The positioning plate 24 is a continuous plate structure. The sole is located inside the positioning plate 24, which positions and fixes the sole to ensure it is placed in the correct position. Simultaneously, to ensure the edge-pressing shaft 10 can properly press the edge of the sole, a receiving cavity 25 is provided on the processing table 5, and the positioning plate 24 slides within the receiving cavity 25. When the sole is placed on the processing table 5, the positioning plate 24 extends out of the receiving cavity 25 to position and fix the sole. During pressing, the positioning plate 24 remains within the receiving cavity 25, ensuring the edge-pressing shaft 10 presses the sole. Furthermore, a positioning component is provided within the processing table 5 to fix the positioning plate 24 when it extends out of the receiving cavity 25.

[0040] The processing table 5 has a first groove 26 and a second groove 27, and a third groove 28 connected to the second groove 27. The positioning assembly includes a fourth cylinder 29 installed in the first groove 26. The output end of the fourth cylinder 29 extends into the second groove 27 and is connected to a drive plate 30. A connecting rod 31 is rotatably provided in the processing table 5. The two ends of the connecting rod 31 are rotatably connected to the inner wall of the second groove 27 through bearings. A transmission wheel 32 is fixed on the connecting rod 31. A lifting plate 33 is slidably provided in the second groove 27. The drive plate 30 is connected to the lifting plate 33 through the transmission wheel 32, and the drive plate 30 drives the lifting plate 33 to rise and fall. A support plate 34 is slidably disposed within the third groove 28. One end of the support plate 34 can slide to the outside of the third groove 28 and abut against the positioning plate 24. The support plate 34 and the lifting plate 33 are arranged perpendicularly to each other. The upper end of the lifting plate 33 has a first inclined surface 35, and the support plate 34 has a second inclined surface 36 that cooperates with the first inclined surface 35. When the lifting plate 33 rises, the support plate 34 is moved by the action of the first inclined surface 35 and the second inclined surface 36, so that the support plate 34 moves to the outside of the third groove 28 and abuts against the positioning plate 24, thereby fixing the positioning plate 24 outside the receiving cavity 25. The height of the positioning plate 24 is greater than the height of the processing table 5. The shoe sole is then placed inside the positioning plate 24, thereby fixing and positioning the shoe sole.

[0041] The drive plate 30 has a plurality of first racks 37, which mesh with the gears on the transmission wheel 32. The lifting plate 33 has a plurality of second racks 38 that mesh with the gears on the transmission wheel 32.

[0042] To ensure the stability of the movement of the support plate 34, this design provides a sliding groove 39 on one side of the third groove 28. A slider 40 is installed in the sliding groove 39. One end of the slider 40 is fixedly connected to the support plate 34, and a return spring 41 is connected between the slider 40 and the sliding groove 39.

[0043] A controller 42 is installed on the frame 1. The first cylinder 7, the second cylinder 19, the third cylinder 22, the fourth cylinder 29, and the motor 14 are all connected to the controller 42 for communication feedback control. Specifically, the controller 42 is electrically connected to the first cylinder 7, the second cylinder 19, the third cylinder 22, the fourth cylinder 29, and the motor 14 through a circuit board and wires. The controller 42 controls the automated operation and linkage of the first cylinder 7, the second cylinder 19, the third cylinder 22, the fourth cylinder 29, and the motor 14 through PLC control technology or other existing automation control technology. The automatic control technology of the controller 42 and the operating principles of the first cylinder 7, the second cylinder 19, the third cylinder 22, the fourth cylinder 29, and the motor 14 are all existing technologies and will not be described in detail.
