Description

Technical Field

[0001] This utility model belongs to the technical field of shoemaking pressing, and in particular relates to a rapid pressing device for shoemaking. Background Technology

[0002] Rapid pressing during shoe manufacturing is a crucial step in ensuring a tight bond between the sole and the upper. By pressing the sole and upper together, a strong bond can be formed. Applying sufficient pressure and time allows the adhesive to work effectively, ensuring a strong bond between the two and guaranteeing the overall structural stability and lifespan of the shoe. This process can significantly shorten the bonding time between the sole and the upper, thereby accelerating production and improving overall production efficiency.

[0003] Common pressing equipment involves applying adhesive to the bonding areas of the sole and upper, placing the shoe last inside the upper, and then pressing the last down to complete the bonding between the sole and upper. However, in actual use, applying external force can easily cause misalignment between the sole and upper, affecting the bonding effect. Therefore, we provide a rapid pressing device for shoe manufacturing to solve the aforementioned technical problems. Utility Model Content

[0004] The purpose of this invention is to provide a rapid pressing device for shoemaking, which solves the problems in the background art by the specific structural design of the pressing limiting component and the lifting pressing component.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model is a rapid pressing device for shoemaking, including a pressing limiting component. The pressing limiting component includes a pressing support plate. A guide groove is formed on the upper surface of the pressing support plate. Two hollow limiting seats are symmetrically slidably arranged on the upper surface of the pressing support plate. The hollow limiting seats are slidably engaged with the guide groove. A plurality of hollow pressing columns are slidably arranged on one side of the hollow limiting seats. A lifting pressing component is fixedly connected to the upper surface of the pressing support plate. The lifting pressing component includes two symmetrically arranged and vertically movable lifting pressing columns. The upper ends of the lifting pressing columns are both inclined slope structures. A transmission trapezoidal column is slidably arranged between the two lifting pressing columns. The transmission trapezoidal column is slidably engaged with both lifting pressing columns.

[0006] The present invention is further configured such that a through-hole corresponding to a hollow pressing column is provided on one side of the hollow limiting seat, the hollow pressing column is slidably disposed inside the corresponding through-hole, and a limiting support column corresponding to a hollow pressing column is fixedly connected to the inner side wall of the hollow limiting seat, and the limiting support column and the corresponding hollow pressing column are slidably engaged.

[0007] The present invention is further configured such that a limiting ring is fixedly connected to the periphery of the hollow pressing column, a limiting spring is fixedly connected between the limiting ring and the inner wall of the hollow limiting seat, the limiting spring is sleeved on the outside of the corresponding limiting support column, and a transmission rack is fixedly connected to one side of the hollow limiting seat near the lifting pressing assembly; a pressing support seat is fixedly connected to the upper surface of the pressing support plate, a drive disk is rotatably connected to the top of the pressing support seat, two transmission connecting rods are symmetrically rotatably connected to the lower surface of the drive disk, and one end of the transmission connecting rod is rotatably connected to the corresponding hollow limiting seat through an ear plate.

[0008] The present invention is further configured such that the lifting and pressing assembly includes a lifting and pressing seat fixedly connected to the upper surface of the pressing support plate, a transmission gear meshing with a transmission rack is rotatably connected to the top of the lifting and pressing seat, and a guide rail is fixedly connected to the upper surface of the lifting and pressing seat; a drive screw is rotatably connected between the guide rail and the two inner side walls, the drive screw is fixedly connected to the transmission gear, an extension support plate threadedly engaged with the drive screw is slidably disposed inside the guide rail, and a pressing support platform is fixedly connected to the lower surface of the extension support plate.

[0009] The present invention is further configured such that two vertical sliding grooves are provided inside the pressing support platform, and a horizontal sliding groove is provided between the two vertical sliding grooves. The lifting pressing column is slidably disposed inside the corresponding vertical sliding groove, and the transmission trapezoidal column is slidably disposed inside the horizontal sliding groove. A reset sliding groove is provided on the inner side wall of the horizontal sliding groove. A vertical plate that slides with the reset sliding groove is fixedly connected to one side of the transmission trapezoidal column. A reset spring is fixedly connected between the vertical plate and the inner wall of the reset sliding groove.

[0010] This utility model has the following beneficial effects: 1. By setting a pressing limiting component, this utility model controls the rotation of the drive disc. Under the action of the transmission connecting rod, the two hollow limiting seats move synchronously and approach each other. The hollow pressing column is in close contact with the side of the shoe to be pressed. As the hollow limiting seat continues to move, the hollow pressing column slides until all the hollow pressing columns are in close contact with the side of the shoe to be pressed. This achieves the limitation of the position of the side of the shoe to be pressed during the pressing process, avoiding the displacement during the pressing process and affecting the pressing effect.

[0011] 2. This utility model, by setting up a pressing limit component and a lifting pressing component, during the horizontal movement of the hollow limit seat, the transmission rack moves and drives the transmission gear to rotate. The drive screw rotates synchronously with the transmission gear, causing the pressing support platform to move downward, which in turn drives the lifting pressing column to move downward. When one of the lifting pressing columns comes into contact with the shoe last, it moves upward as the pressing support platform moves downward, causing the transmission trapezoidal column to slide horizontally, so that the other lifting pressing column moves further downward until the two lifting pressing columns are respectively in contact with the shoe toe and the shoe heel, thereby maintaining the uniform force on the shoe to be pressed during the pressing process.

[0012] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model. Specific Implementation Example 1

[0025] Please see Figure 1-7 This utility model is a rapid pressing device for shoemaking, including a pressing limiting component 1. Specifically, the pressing limiting component 1 includes a pressing support plate 101. A guide groove 102 is provided on the upper surface of the pressing support plate 101. Two hollow limiting seats 103 are symmetrically slidably arranged on the upper surface of the pressing support plate 101. During shoe pressing, the sole and upper with adhesive are placed between the two hollow limiting seats 103. The hollow limiting seats 103 and the guide groove 102 slide together. Several hollow pressing columns 104 are slidably arranged on one side of the hollow limiting seats 103. The hollow pressing columns 104 are in close contact with the side of the shoe to be pressed to limit the position of the shoe.

[0026] Furthermore, a lifting pressing assembly 2 is fixedly connected to the upper surface of the pressing support plate 101. The lifting pressing assembly 2 includes two symmetrically arranged and vertically movable lifting pressing columns 201. The upper ends of the lifting pressing columns 201 are both inclined slope structures, and a transmission trapezoidal column 202 is slidably arranged between the two lifting pressing columns 201. The transmission trapezoidal column 202 and the two lifting pressing columns 201 are slidably engaged. The lower ends of the lifting pressing columns 201 are made of rubber to avoid damaging the shoe surface when in contact with it.

[0027] The operation process of this embodiment is as follows: the sole and upper of the shoe to be pressed are placed between two hollow limiting seats 103 (a shoe last is placed inside the upper, which is adapted to the inside of the shoe, and the part near the heel is exposed to facilitate pressing and support). The two hollow limiting seats 103 are controlled to move synchronously and move closer to each other. The hollow pressing column 104 moves synchronously with the hollow limiting seat 103. When the hollow pressing column 104 is in contact with the side of the shoe to be pressed, as the hollow limiting seat 103 continues to move, the hollow pressing column 104 in contact with the side of the shoe to be pressed slides horizontally until all the hollow pressing columns 104 on the two hollow limiting seats 103 are in close contact with the side of the shoe to be pressed, thereby realizing the position limitation of the shoe to be pressed.

[0028] While defining the position of the shoe to be pressed, the two lifting pressing columns 201 move downwards simultaneously. When one of the lifting pressing columns 201 contacts the shoe last inside the shoe upper, as both lifting pressing columns 201 continue to move downwards, the lifting pressing column 201 in contact with the shoe last is obstructed, applying pressure to the shoe last while sliding upwards. Under the sliding cooperation between the lifting pressing column 201 and the transmission trapezoidal column 202, the transmission trapezoidal column 202 moves horizontally and then squeezes the other lifting pressing column 201, causing the other lifting pressing column 201 to move further downwards until the other lifting pressing column 201 is in close contact with the surface of the shoe upper, thereby realizing the pressing operation between the shoe upper and the slope. Specific Implementation Example 2

[0030] Please see Figure 2-4 Based on the first specific embodiment, specifically, a through opening corresponding to the hollow pressing column 104 is provided on one side of the hollow limiting seat 103. The hollow pressing column 104 is slidably disposed inside the corresponding through opening, and a limiting support column 105 corresponding to the hollow pressing column 104 is fixedly connected to the inner side wall of the hollow limiting seat 103. The limiting support column 105 and the corresponding hollow pressing column 104 are slidably engaged.

[0031] Furthermore, a limiting ring is fixedly connected to the periphery of the hollow pressing column 104. In the initial state, the limiting ring is in contact with the inner wall of the hollow limiting seat 103 away from the limiting support column 105. A limiting spring 106 is fixedly connected between the limiting ring and the inner wall of the hollow limiting seat 103. The limiting spring 106 is sleeved on the outside of the corresponding limiting support column 105, and a transmission rack 107 is fixedly connected to the side of one of the hollow limiting seats 103 near the lifting pressing assembly 2.

[0032] Furthermore, a pressing support base 108 is fixedly connected to the upper surface of the pressing support plate 101, and a drive disk 109 is rotatably connected to the top of the pressing support base 108. Two transmission connecting rods 110 are symmetrically rotatably connected to the lower surface of the drive disk 109. One end of the transmission connecting rod 110 is rotatably connected to the corresponding hollow limit seat 103 through an ear plate. A drive motor is fixedly installed on the lower surface of the pressing support plate 101, and the output shaft of the drive motor is fixedly connected to the drive disk 109.

[0033] The operation process of this embodiment is as follows: the sole and upper of the shoe, coated with adhesive, are placed on the pressing support seat 108. The drive motor is started to drive the drive disk 109 to rotate. The two transmission links 110 move synchronously with the drive disk 109. Under the connection of the transmission links 110, the two hollow limiting seats 103 slide synchronously along the guide groove 102 and move closer to each other. When the hollow pressing column 104 is in contact with the peripheral side of the shoe to be pressed, as the hollow limiting seat 103 continues to move, the hollow pressing column 104 is restricted by the shoe to be pressed and slides in the opposite direction along the through opening. The hollow pressing column 104 moves radially along the surface of the limiting support column 105, and the limiting spring 106 is compressed. As the hollow limiting seat 103 continues to move, the hollow pressing column 104 successively comes into close contact with the peripheral side of the shoe to be pressed until all the hollow pressing columns 104 are in close contact with the peripheral side of the shoe to be pressed, thereby realizing the position limitation of the shoe to be pressed. Specific Implementation Example 3

[0035] Please see Figure 5-7 Based on specific embodiments one and two, specifically, the lifting and pressing assembly 2 further includes a lifting and pressing seat fixedly connected to the upper surface of the pressing support plate 101. The top of the lifting and pressing seat is rotatably connected to a transmission gear 203 that meshes with the transmission rack 107. The upper surface of the lifting and pressing seat is fixedly connected to a guide rail 204. When the corresponding hollow limit seat 103 moves horizontally, the transmission rack 107 moves synchronously, driving the transmission gear 203 to rotate.

[0036] Furthermore, a drive screw 205 is rotatably connected between the guide slide rail 204 and the two inner side walls. The drive screw 205 is fixedly connected to the transmission gear 203. An extension support plate that is threadedly engaged with the drive screw 205 is slidably provided inside the guide slide rail 204. A pressing support table 206 is fixedly connected to the lower surface of the extension support plate.

[0037] Furthermore, two vertical grooves are provided inside the pressing support platform 206. The length of the vertical groove near the heel is greater than that near the toe. The lifting pressing column 201 near the heel contacts the shoe last first. A horizontal groove is provided between the two vertical grooves. The lifting pressing column 201 is slidably installed inside the corresponding vertical groove. The lifting pressing column 201 is slidably installed inside the corresponding vertical groove through elastic elements (that is, vertical grooves are provided on the two inner sidewalls of the vertical groove, and extension blocks that slide with the vertical groove are fixedly connected to the two sides of the lifting pressing column 201. An elastic element is fixedly connected between the extension block and the bottom of the vertical groove). The transmission trapezoidal column 202 is slidably installed inside the horizontal groove.

[0038] Furthermore, a reset groove 207 is provided on the inner wall of the horizontal slide groove, and a vertical plate that slides with the reset groove 207 is fixedly connected to one side of the transmission trapezoidal column 202. A reset spring 208 is fixedly connected between the vertical plate and the inner wall of the reset groove 207.

[0039] The operation process of this embodiment is as follows: During the horizontal movement of the hollow limiting seat 103, the transmission rack 107 moves synchronously. Under the meshing action of the transmission rack 107 and the transmission gear 203, the transmission gear 203 rotates, thereby driving the drive screw 205 to rotate. Under the threaded engagement of the drive screw 205 and the extension support plate, the extension support plate slides downward along the inside of the guide rail 204, driving the pressing support platform 206 to move downward synchronously. The two lifting pressing columns 201 move downward synchronously with the pressing support platform 206. When the lifting pressing column 201 near the heel first contacts the shoe last, as the extension support plate continues to move downward, the lifting pressing column 201 in contact with the shoe last is obstructed and moves upward. Under the sliding engagement of the lifting pressing column 201 and the transmission trapezoidal column 202, the transmission trapezoidal column 202 moves horizontally, the return spring 208 is compressed, thereby pushing the other lifting pressing column 201, causing the lifting column 201 near the toe to move upward. The pressing column 201 moves further downward until the lifting pressing column 201 near the toe is in close contact with the toe surface. At this time, the hollow pressing columns 104 are in close contact with the sides of the shoe to be pressed. As the hollow limiting seat 103 continues to move, the hollow pressing column 104 restricts the shoe to be pressed while applying pressure to its sides. At the same time, the extension plate moves further downward, causing the two lifting pressing columns 201 to synchronously adjust the applied pressure, so that the upper and sole are fully pressed together. When the pressing is finished, the drive plate 109 rotates in the opposite direction, the two hollow limiting seats 103 move away from each other, and the transmission gear 203 rotates in the opposite direction, causing the drive screw 205 to rotate in the opposite direction. The two lifting pressing columns 201 gradually move away from the shoe to be pressed. Under the elastic recovery action of the return spring 208 and the sliding cooperation between the lifting pressing column 201 and the transmission trapezoidal column 202, the lifting pressing column 201 and the transmission trapezoidal column 202 return to their initial state, and then the pressed shoe is taken out.
