Description

Technical Field

[0001] This utility model relates to the field of shoemaking equipment technology, and in particular to a shoe upper pressing and heating device used in shoemaking. Background Technology

[0002] The upper refers to the side part of a shoe, usually connecting the sole and the upper, and serves to support and protect the foot. During the shoemaking process, some upper materials need to be heat-pressed to soften the material, making it easier to shape and sew the upper.

[0003] Current heat pressing equipment typically requires workers to remove the shoe uppers directly from the mold after heat pressing, which lacks sufficient anti-scalding measures. This makes workers' arms susceptible to burns from the heating plates and molds of the heat pressing equipment. Therefore, there is a need to provide a heat pressing device that is safer for the heat pressing operation. Utility Model Content

[0004] In view of the above problems, this utility model provides a shoe upper pressing device for shoe manufacturing.

[0005] To achieve the above-mentioned objectives, the technical solution adopted by this utility model is as follows:

[0006] A shoe upper pressing device for shoe manufacturing is provided, including a mounting bracket, a placement platform at the bottom of the mounting bracket, a movable frame that moves horizontally on the placement platform, a positioning component for positioning the shoe upper on the movable frame, a limiting component for restricting the movement of the movable frame on the placement platform, a pressing component on the mounting bracket above the placement platform, a lower mold base for positioning the shoe upper on the movable frame, a cooling component inside the lower mold base, and a mounting plate including a pressing plate at the bottom of the mounting plate. A driving component is provided on the mounting bracket to drive the mounting plate to move vertically up and down.

[0007] Furthermore, the cooling assembly includes a cooling cavity opened in the lower mold base, a heat dissipation fan is installed on the movable frame, the air inlet of the heat dissipation fan faces upward and is connected to an air inlet pipe, several heat dissipation holes communicating with the cooling cavity are opened on the side wall of the lower mold base, and an air outlet is opened on the bottom wall of the lower mold base, which is connected to the air inlet pipe.

[0008] Furthermore, the lower mold base is detachably connected to the movable frame via bolts, and the air inlet pipe and air outlet are movably connected.

[0009] Furthermore, the positioning assembly includes positioning blocks that are horizontally slidably mounted on the movable frame. The positioning blocks are located on both sides of the lower mold base. The movable frame is provided with a second driving member for driving the two positioning blocks to move. The second driving member includes a drive motor, a drive gear, and a driven rack. The positioning blocks are horizontally slidably connected to the movable frame through a first guide rod. The driven rack is fixedly mounted on the positioning blocks parallel to the first guide rod. The drive motor is mounted on the movable frame and is used to drive the drive gear to rotate. The drive gear meshes with the driven rack.

[0010] Furthermore, the positioning block includes a connecting seat and a movable block. The first guide rod and the driven rack are both disposed on the connecting seat. The movable block is disposed on the side of the connecting seat near the lower mold base, parallel to the connecting seat, through the second guide rod. A second spring is sleeved on the second guide rod to drive the movable block to move along the side away from the connecting seat.

[0011] Furthermore, a contact sensor is installed on the connector, and the drive motor stops when the movable block comes into contact with the contact sensor.

[0012] Furthermore, the limiting component includes a limiting pin and a pressing part. A slide rail is horizontally arranged on the placement platform, and the movable frame is slidably connected to the slide rail. A limiting rack is arranged along the length direction of the slide rail. The limiting pin is horizontally slidably connected to the bottom wall of the movable frame. A limiting tooth is provided at the end of the limiting pin near the limiting rack. The limiting tooth engages with the limiting rack. A handle is provided on the side wall of the movable frame. A connecting frame that slides along its sliding direction is provided on the bottom wall of the movable frame. A connecting rod is hinged to the side wall of the connecting frame. The end of the connecting rod away from the connecting frame is connected to the limiting pin. The pressing part is fixedly connected to the connecting frame and located inside the handle. A first spring is provided on the handle for pushing the pressing part away from the handle so that the limiting tooth engages with the limiting rack.

[0013] Furthermore, a baffle is provided on the placement platform, and when the moving frame comes into contact with the baffle, the lower mold base is located directly below the heat press plate.

[0014] The beneficial effects of this utility model are as follows: When performing the pressing operation on the shoe upper, the operator first holds the handle on the moving frame and pulls the moving frame out to one side below the pressing plate. After installing the shoe upper into the upper and lower mold bases, the positioning component keeps the shoe upper in position. Then, the moving frame is pushed to the bottom of the pressing plate to release the restriction of the positioning component, and the shoe upper can be pressed. In addition, the cooling component can continuously cool the lower mold base at other times except when pressing is being performed, so as to avoid the lower mold base temperature from being too high and improve the safety of the operator during the pressing process.

[0020] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0021] This application discloses a shoe upper pressing device for shoemaking, referring to... Figure 1 and Figure 2 The system includes a mounting bracket 1, a placement platform 2 at its bottom, a horizontal slide rail on the placement platform 2, a movable frame 3 slidably mounted on the slide rail, a positioning component 4 for positioning the shoe upper on the movable frame 3, and a limiting component on the placement platform 2 for restricting the movement of the movable frame 3. A pressing assembly is located above the placement platform 2 on the mounting bracket 1. Specifically, the pressing assembly includes a mounting plate 61, a pressing plate 62, and a first driving member 63. The pressing plate 62 is fixed to the bottom of the mounting plate 61, and the first driving member 63 drives the mounting plate 61 to rise and fall vertically. The first driving member 63 can be a hydraulic cylinder, fixed to the mounting bracket 1, with its piston rod connected and fixed to the mounting plate 61. In other embodiments, the first driving member 63 can also be a motor-driven screw lifting seat. An installation space is formed between the pressing plate 62 and the mounting plate 61. An electric heating wire is installed within the installation space, fitted to the pressing plate 62, thereby heating the pressing plate 62.

[0022] Reference Figure 3 and Figure 4In this embodiment of the application, the positioning component 4 includes positioning blocks 41 that are horizontally slidably mounted on the moving frame 3. The positioning blocks 41 are located on both sides of the lower mold base 7 and are symmetrically arranged. The moving frame 3 is provided with a second driving member 63 for driving the two positioning blocks 41 to move. Specifically, the second driving component 63 includes a drive motor 42, a drive gear 43, and a driven rack 44. Two first guide rods 45 are vertically fixed to the surfaces of the two positioning blocks 41 that are far apart from each other. The first guide rods 45 pass through the moving frame 3, making the positioning blocks 41 horizontally connected to the moving frame 3. The driven rack 44 is fixed to the positioning blocks 41 parallel to the first guide rods 45. The drive motor 42 is fixedly connected to the moving frame 3 by bolts. The output shaft of the drive motor 42 is coaxially connected to the drive gear 43. The drive gear 43 meshes with the driven rack 44. By driving the drive gear 43 to rotate forward and backward, the positioning blocks 41 can be moved horizontally. By bringing the two positioning blocks 41 closer together, the shoe upper placed on the lower mold base 7 can be clamped, allowing the moving frame 3 to maintain the shoe upper's position during movement. When the pressing plate 62 needs to press and lower the shoe upper, the drive motor 42 drives the two positioning blocks 41 to move synchronously away, allowing the pressing plate 62 to smoothly press and heat the shoe upper.

[0023] Furthermore, to prevent the positioning block 41 from excessively compressing the shoe upper during the pressing process, causing deformation and affecting the pressing effect, in this embodiment, the positioning block 41 includes a connecting seat 411 and a movable block 412. The first guide rod 45 and the driven rack 44 are both mounted on the connecting seat 411. The movable block 412 is horizontally slidable on the side of the connecting seat 411 near the lower mold base 7, parallel to the moving direction of the connecting seat 411, via a second guide rod 413. A stop is provided at the end of the second guide rod 413 away from the movable block 412, which restricts the movable block 412 from moving away from the... During the process of connecting seat 411, the second guide rod 413 disengages from the connecting seat 411. A second spring 414 is sleeved on the second guide rod 413 to drive the movable block 412 away from the connecting seat 411. One end of the second spring 414 abuts against the connecting seat 411 and the other end abuts against the movable block 412. Through the second spring 414, when the movable block 412 contacts the shoe upper and is pushed close to the connecting seat 411, it can push the movable block 412 with a small elastic force to keep it in contact with the shoe upper, which can effectively prevent the shoe upper from shifting on the lower mold seat 7 during the movement of the moving frame 3.

[0024] Furthermore, a contact sensor 415 can be installed on the connecting base 411. The contact sensor 415 is electrically connected to the drive motor 42. When the movable block 412 contacts the contact sensor 415, the drive motor 42 stops to prevent the positioning block 41 from excessively squeezing the shoe upper.

[0025] In this embodiment, the limiting component includes a limiting pin 51 and a pressing part 52. A limiting rack 53 is provided along the length of the slide rail. The limiting pin 51 is horizontally slidably connected to the bottom wall of the movable frame 3 perpendicular to the sliding direction of the movable frame 3. A limiting tooth is provided at one end of the limiting pin 51 near the limiting rack 53. When the limiting pin 51 slides out from the side of the movable frame 3, the limiting tooth can cooperate with the limiting rack 53 to restrict the movement of the movable frame 3 on the slide rail.

[0026] A handle 8 is provided on the side wall of the movable frame 3. A connecting frame 54 is slidably provided on the bottom wall of the movable frame 3 along its sliding direction. A connecting rod 55 is hinged to the side wall of the connecting frame 54. The end of the connecting rod 55 away from the connecting frame 54 is connected to a limiting pin 51. A pressing part 52 is fixedly connected to the connecting frame 54 and located inside the handle 8. A first spring 56 is provided on the handle 8 to push the pressing part 52 away from the handle 8 so that the limiting tooth and the limiting rack 53 can be engaged. When the operator pushes or pulls the movable frame 3, he / she grips the handle 8 and presses the pressing part 52 close to the handle 8, which will cause the limiting pin 51 to extend, so that the limiting tooth and the limiting rack 53 are disengaged, and the movable frame 3 can move normally. When the movable frame 3 is in place, the handle 8 is released. The restoring force generated by the first spring 56 causes the limiting pin 51 to retract below the movable frame 3, so that the limiting tooth and the limiting rack 53 are engaged, and the movable frame 3 can stop moving.

[0027] Furthermore, in order to ensure that the lower mold base 7 can be accurately moved below the heat press plate 62, a baffle 57 is provided on the placement platform 2. When the moving frame 3 abuts against the baffle 57, the lower mold base 7 is located directly below the heat press plate 62.

[0028] In this embodiment, the cooling assembly may include a cooling cavity 71 formed within the lower mold base 7. A cooling fan 72 is fixedly mounted on the movable frame 3, with the air inlet of the cooling fan 72 facing upwards and connected to an air inlet pipe 73. Several heat dissipation holes 74 communicating with the cooling cavity 71 are formed on the side wall of the lower mold base 7, and an air outlet 75 is formed on the bottom wall of the lower mold base 7, connected to the air inlet pipe 73. By turning on the cooling fan 72, outside air can be drawn into the cooling cavity 71 from the various heat dissipation holes 74 of the lower mold base 7. The air inside the lower mold base 7 is blown downwards by the cooling fan 72. An exhaust duct is formed on the placement platform 2, so that the cooling fan 72 can continue to work and exhaust air normally during the movement of the movable frame 3, cooling the lower mold base 7 and avoiding the inconvenience caused to the operator to pick up and put down the shoe uppers due to the increased temperature of the lower mold base 7 after continuous pressing operations.
