Description

Technical Field

[0001] The invention relates to the technical field of shoe-making equipment, in particular to a sole pressing machine structure for shoe-making. Background Art

[0002] During the shoe manufacturing process, the upper and the sole must be bonded together. The bonding process is to apply adhesive to the bottom surface of the upper and the top surface of the sole respectively and then bond them together. In order to make the two bond more tightly, a machine commonly known as a sole pressing machine is used to provide a top-down pressing force to the upper, and at the same time provide lateral pressing force to the sides of the upper and the sole, so that the upper and the sole can be tightly bonded.

[0003] At present, when processing and molding the soles, the shoe-making press-soles machine drives the molding mold through the hydraulic system to mold the soles and peripheries of the shoes to be processed. The traditional method is that the oil cylinder directly pushes the edge-pressing rubber block, and the oil cylinder cannot be made too small. If the pressure is small, the adhesion is poor, and it also affects the fit between the edge-pressing rubber block and the edge shape of the shoe; at the same time, different edge-pressing rubber blocks are subjected to uniform force, so that when pressing, the rubber blocks do not press the shoes at the same time, which affects the pressing quality. Especially when molding the soles of shoes with large changes in shape (such as mid-heel shoes), the edge-pressing rubber block often fails to press the parts with large changes in the curved surface, resulting in a decrease in the quality rate of the molded shoes. The reason is that the rubber block to be pushed by a press-side oil cylinder cannot move synchronously with the rubber block at the bottom. When pressing the soles with large changes in the curved surface, the side rubber block cannot change with the height changes of the soles, resulting in some places not being pressed in place. Summary of the invention

DETAILED DESCRIPTION

[0017] The concept, specific structure and technical effects of the present invention will be further described below in conjunction with the accompanying drawings to fully understand the purpose, characteristics and effects of the present invention.

This is merely for the convenience of description and does not indicate or imply that the device or element must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it cannot be understood as a limitation on the present invention.

[0019] See also Figure 1 , 2, 3, 4, 5, and 6 are schematic diagrams of the structure of a preferred embodiment of the present invention. The present invention is related to a pressing mechanism, which has a support seat 1, and a zoom cavity 11 is constructed by enclosing the support seat 1, and an accompanying material 2 is placed in the zoom cavity 11; further preferably, the support seat 1 is a hollow frame-shaped structure formed by a combination of a bottom plate 12, two side plates 13, and an upper cover 14, and the zoom cavity 11 is the hollow part of the support seat 1, which has a simple structure and is convenient for manufacturing and assembly. When the zoom cavity 11 contracts, the accompanying material 2 outputs power to drive the profiling block 3, so that the profiling block 3 extends toward the pressed object and presses the pressed object. The profiling block 3 is arranged on the corresponding side of the zoom cavity 11 and can extend automatically according to the curvature of the pressed object, so that the forward end of the profiling block 3 can be arranged in a profiling manner according to the curvature of the pressed object and give appropriate pressing force corresponding to the curvature of each area. The present invention utilizes the contraction of the zoom chamber 11 to act on the accompanying material 2, so that the accompanying material 2 can achieve synchronous action on the multiple arranged profiling blocks 3, and then utilizes the profiling blocks 3 to adaptively match the curvature of the pressed object to adjust and extend, so that the profiling blocks 3 can fit with the curvature of the pressed object and give appropriate pressing force corresponding to the curvature of each area, ensuring balanced pressing, achieving the effect of close and smooth fitting according to the curvature, and reducing the situation of inadequate pressing.

[0020] Figure 1 , 2 As shown in , 3, 4, 5, and 6, in this embodiment, the accompanying material 2 is a plurality of granular elements, and a power push block 4 is arranged in the zoom chamber 11; preferably, the accompanying material 2 is a steel ball with sufficient hardness, and of course hard particles of other materials, such as sand, are not excluded. When the zoom chamber 11 is in a contracted state, the power push block 4 pushes the accompanying material 2, so that the accompanying material 2 moves toward the direction of the profiling block 3 and supports the profiling block. The power push block 4 pushes the accompanying material 2 horizontally, so that the accompanying material 2 moves and squeezes each other, and the accompanying material 2 supports the profiling block 3, and according to the extension of different profiling blocks 3, the accompanying material 2 moves in an adaptive diversion manner, so that the profiling block 3 in the same zoom chamber can extend along the curvature of the pressed object and give appropriate pressing force to the curvature of each area. The profiling blocks 3 are subjected to force synchronously, and the pressure is balanced, which improves the pressing effect.

[0021] In this embodiment, the power push block 4 and the profiling block 3 are respectively arranged at the two ports of the zoom chamber 11. It is preferred that the power push block 4 and the profiling block 3 form a linear relative relationship, and the transmission is smooth and balanced. The power push block 4 is connected to the oil cylinder 5, and the expansion and contraction of the oil cylinder 5 is used to drive the power push block 4 to move, so as to realize mechanical pushing of the accompanying material 2, and the accompanying material 2 then pushes the profiling block. The structure is simple, the investment cost is low, and the working environment is easy to control and maintain. The profiling block 3 is a flat block and arranged sideways. The adjacent profiling blocks 3 are close together to form a row. When working, the profiling block 3 extends automatically when it encounters the concave and convex parts of the pressed object, forming an arc that matches the pressed object and pressing the pressed object to realize the pressing work. In this embodiment, the profiling block 3 also forms a reset linkage relationship with the power push block 4, so that when the power push block 4 is reset, the profiling block 3 is driven to reset for the next pressing work. In this embodiment, the thickness of the side-standing profiling block 3 is greater than the diameter of the accompanying material 2, so that the accompanying material 2 can effectively support the corresponding end of the profiling block 3, allowing the profiling block 3 to accurately and effectively extend and press.

[0022] The oil cylinder 5 is installed on the support seat 1 and is located at the rear side of the power push block 4. The extension direction of the oil cylinder 5 is the same as the movement direction of the power push block 4, realizing linear push and pull. Furthermore, in this embodiment, there are two or more oil cylinders 5 fixed side by side on the bottom plate 12, and the two or more oil cylinders 5 arranged side by side move synchronously to obtain sufficient driving force to meet the pressing force and improve the pressure balance. The oil cylinder 5 of this embodiment is clamped and fixed by the bottom plate 12 and the upper cover 14, so as to realize the upper and lower fixation and achieve the internal storage effect, which is also beneficial to protect the oil cylinder. In order to facilitate assembly and maintenance, the upper cover 14 of this embodiment is divided into two sections, front and rear. The front section upper cover covers and constructs the zoom chamber 11, and the rear section upper cover covers and fixes the oil cylinder. In this embodiment, oil guide holes 15 are also opened on the bottom plate 12 and the upper cover 14 respectively, which is beneficial to the connection between the oil cylinder 5 and the external pressure oil. The telescopic end of the oil cylinder 5 is provided with an annular groove 51, and the rear end of the power push block 4 is provided with a U-shaped claw 41. The axial connection between the telescopic end of the oil cylinder 5 and the power push block 4 is realized by the clamping connection between the annular groove 51 and the U-shaped claw 41. The structure is simple and convenient for disassembly and maintenance.

[0023] The reset linkage relationship between the profiling block 3 and the power push block 4 in this embodiment is realized by the following structure: a long through hole 31 is provided on the profiling block 3, and the length direction of the long through hole 31 is the same as the extension direction of the profiling block 3; a reset cross bar 6 is inserted into the long through hole 31, and the axial direction of the reset cross bar 6 is perpendicular to the extension direction of the profiling block 3, and the end of the reset cross bar 6 extends out of the zoom cavity 11 and is connected to the power push block 4 through the pull rod 7, so that when the power push block 4 is reset, the profiling block 3 is driven to reset through the pull rod 7 and the reset cross bar 6, and the length of the long through hole 31 and the installation position of the reset cross bar 6 meet the extension, top pressure and reset work requirements of the profiling block 3. When resetting, the reset cross bar 6 acts on one end of the long through hole 31 and pulls the profiling block 3 to reset, which has a simple structure, is easy to control, and has mechanical movement, stable and reliable action. When the zoom chamber 11 contracts, the oil cylinder 5 drives the power push block 4 to move, and the pull rod 7 drives the reset cross bar 6 to follow the movement. Utilizing the characteristics of the long through hole 31, the reset cross bar 6 releases the profiling block 3. At this time, the profiling block 3 can extend and press under the push of the accompanying mass 2, thereby realizing the extending and pressing work of the profiling block 3.

[0024] In this embodiment, the two ends of the reset cross bar 6 extend from the zoom cavity 11 and are connected to one end of the pull rod 7, and the other end of the pull rod 7 is connected to the convex pin 42 preset on the power push block, and the convex pin 42 extends from the preset avoidance portion of the support seat 1. In this embodiment, avoidance holes are provided on the side plate 13 corresponding to the extended parts of the reset cross bar 6 and the convex pin 42 to meet the movement of the reset cross bar 6 and the convex pin 42. The structure is simple and reasonable, meets the drive connection, and can optimize the distributed connection between the components, which is conducive to the modularization of the pressing mechanism and is convenient for subsequent installation and implementation.

[0025] Figure 1 As shown, in this embodiment, the top pressing side of the profiling block 3 is provided with a shaping substrate 8, and the shaping substrate 8 is closely attached to the object to be pressed under the top pressing of the profiling block 3, and the shaping substrate 8 is bent to form an arc that matches the object to be pressed. Preferably, the shaping substrate 8 is a rubber sheet or a silicone sheet, which plays a cushioning role, increases the continuity of the pressed curved surface, and protects the object to be pressed. The shaping substrate 8 can be fixed on the support seat 1 or on the machine carrier.

[0026] Figure 5 , 6 As shown, the present invention also provides a sole pressing machine for shoemaking, which has the above-mentioned pressing mechanism, uses a mechanical method to push the steel ball, and the steel ball in turn pushes the profiling block. The profiling block forms an arc that matches the shoe when it touches the concave and convex parts of the shoe, which can achieve the effect of the shoe edge being able to fit tightly and smoothly along the arc, realize seamless pressing, and improve production efficiency and quality.

[0027] In this embodiment, the pressing mechanism is arranged on the left and right sides of the shoe outsole placed on the sole pressing machine, and the pressing mechanisms on the left and right sides are symmetrical, which is convenient for manufacturing and assembly, realizes left and right pressing, and further can achieve synchronous control of pressing operation; of course, in actual application, a corresponding pressing mechanism can also be arranged on the lower side of the outsole to realize three-way pressing of the shoe outsole, so that the upper and the shoe outsole can be closely bonded. The profiling block forms an arc that matches the shoe when it touches the concave and convex parts of the shoe, which can achieve the effect that the shoe edge can be closely fitted and flattened according to the arc, and realize seamless pressing.
