Description

Technical Field

[0001] This utility model relates to the field of bottom pressing machines, and in particular to a pressing head structure for a moldless bottom pressing machine. Background Technology

[0002] Currently, after the sole and upper are manufactured, they are bonded together with glue. However, the unevenness of manual bonding can result in gaps between the sole and upper, affecting the overall quality of the shoe.

[0003] With continuous research and development by technicians in this field, some shoe pressing machines for pressing soles and uppers have appeared on the market. These shoe pressing machines typically use a pre-set shoe mold, which includes a base, a pressure plate, and a drive device. The base has a pressing cavity, and the pressure plate has a pressing part. The drive device is connected to the pressure plate. By placing the shoe into the pressing cavity, the drive device controls the pressure plate to move towards the base so that the pressing part enters the pressing cavity and performs the pressing operation on the shoe. However, the existing pressing machine structure design is flawed. Because the pressing part on the pressure plate used for pressing the shoe is a non-replaceable design, different shoe models require different pressure plates to be customized, resulting in high production costs and failing to achieve universality. This makes it unsuitable for pressing soles of different shoe models, with poor usability and a limited range of applications.

[0004] Therefore, a new technical solution needs to be researched to address the above problems. Utility Model Content

[0005] In view of this, the present invention addresses the deficiencies of the existing technology and its main purpose is to provide a moldless sole pressing machine press head structure. Through the detachable design of the pressing part, the corresponding pressing part is configured on the pressing plate according to different shoe shapes to realize the pressing operation of different shoes. It is simple to operate, convenient to use, meets the user's needs, has good usability, and has a wide range of applications.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] As a preferred embodiment, the second mounting part is a mounting groove with a mounting opening, and the first mounting part enters the mounting groove through the mounting opening, with the outer wall of the first mounting part constrained by the inner wall of the mounting groove.

[0009] As a preferred embodiment, the second mounting part extends back and forth along the length of the pressing cavity, and the first mounting part is adjustablely mounted on the second mounting part.

[0010] As a preferred embodiment, a connecting portion is provided between the first mounting portion and the pressing portion, and a clearance opening is provided at the lower end of the second mounting portion, with the connecting portion constrained by the clearance opening.

[0011] As a preferred embodiment, the lower end of the pressure plate is provided with an extended membrane edge, which extends circumferentially around the inner wall of the pressing cavity.

[0012] As a preferred embodiment, the edge of the extended membrane is made of soft rubber.

[0013] As a preferred embodiment, a sealing element is provided at the upper end of the pressing cavity.

[0016] Secondly, the front and rear extension of the second mounting part allows users to adjust the position of the pressing part on the pressure plate according to different shoe types, thereby ensuring the pressing effect of the shoe and making it highly practical. At the same time, the extension of the film edge is used to protect the shoe surface when the pressure plate is pressed down, preventing damage to the shoe surface during the pressing process.

[0017] Furthermore, the sealing element prevents air leakage in the pressing cavity when the pressure plate is pressed against the base, thereby improving the pressing effect and quality of the shoe in the pressing cavity.

[0030] Please refer to Figures 1 to 2 As shown, it illustrates the specific structure of an embodiment of the present invention.

[0031] A moldless bottom pressing machine press head structure includes a base 11 and a pressing mechanism 12; wherein:

[0032] The base 11 has a pressing cavity 111 with an open upper end, and an airbag 112 is provided inside the pressing cavity 111.

[0033] The pressing mechanism 12 is mounted on the base 11 via a mounting bracket 13. The pressing mechanism 12 includes a pressure plate 121, a connecting rod 122, a pressing part 123, and a cylinder 124. The upper end of the pressing part 123 is provided with a first mounting part 125, and the lower end of the pressure plate 121 is provided with a second mounting part 126. The first mounting part 125 is detachably mounted on the second mounting part 126. One end of the pressure plate 121 is rotatably mounted on the base 11. The pressing part 123 is located above the pressing cavity 111. The two ends of the connecting rod 122 are respectively connected to the pressure plate 121 and the cylinder 124. The pressure plate 121 is pressed against the upper end of the base 11 and closes the pressing cavity 111 under the control of the cylinder 124. The pressing part 123 extends into the pressing cavity 111 to perform a pressing operation on the workpiece.

[0034] Specifically, the second mounting part 126 is a mounting groove with a mounting opening 127. The first mounting part 125 enters the mounting groove through the mounting opening 127, and the outer wall of the first mounting part 125 is constrained by the inner wall of the mounting groove. Simultaneously, two pressing cavities 111 are provided, arranged spaced apart horizontally. Correspondingly, two pressing mechanisms 12 are provided, each corresponding to one of the two pressing cavities 111 and arranged spaced apart. Thus, through the detachable design of the pressing parts, corresponding pressing parts can be configured on the pressing plate according to different shoe types to achieve pressing operations for different shoes. Furthermore, the arrangement of two pressing cavities and two pressing mechanisms helps improve the pressing efficiency of shoes, meeting the needs of mass-production pressing. The structure is ingeniously and reasonably designed, simple to operate, convenient to use, meets user needs, has excellent usability, and a wide range of applications.

[0035] In this embodiment, the second mounting part 126 extends back and forth along the length of the pressing cavity. The first mounting part is adjustable back and forth on the second mounting part 126. A connecting part 128 is provided between the first mounting part 125 and the pressing part 123. An avoidance opening 129 is provided at the lower end of the second mounting part 126. The connecting part 128 is restricted by the avoidance opening 129. Thus, the back and forth extension of the second mounting part allows the user to adjust the position of the pressing part on the pressing plate according to different shoe shapes, thereby ensuring the pressing effect of the shoe and making it highly practical.

[0036] Furthermore, the lower end of the pressure plate 121 is provided with an extension film edge 14, which extends circumferentially around the inner wall of the pressing cavity. Preferably, the extension film edge 14 is made of soft rubber, and the pressing part 123 is made of rubber. Thus, the extension film edge is provided to protect the shoe upper when the pressure plate is pressed down, and to prevent damage to the shoe upper during the pressing process.

[0037] Furthermore, a sealing element 15 is provided at the upper end of the pressing cavity 111. The sealing element 15 extends circumferentially around the upper edge of the pressing cavity 111. When the pressure plate 121 is pressed down, the upper end of the sealing element 15 contacts the pressure plate 121. In this way, the sealing element avoids the problem of air leakage in the pressing cavity when the pressure plate is pressed against the base, thereby improving the pressing effect and pressing quality of the shoe in the pressing cavity and making it highly practical.

[0038] The key design feature of this utility model is that it mainly uses a detachable pressing part design. According to different shoe types, corresponding pressing parts are configured on the pressing plate to realize the pressing operation of different shoes. The structure is ingenious and reasonable, simple to operate, convenient to use, meets the user's needs, has good usability, and has a wide range of applications.

[0039] Secondly, the front and rear extension of the second mounting part allows users to adjust the position of the pressing part on the pressure plate according to different shoe types, thereby ensuring the pressing effect of the shoe and making it highly practical. At the same time, the extension of the film edge is used to protect the shoe surface when the pressure plate is pressed down, preventing damage to the shoe surface during the pressing process.

[0040] Furthermore, the sealing element prevents air leakage in the pressing cavity when the pressure plate is pressed against the base, thereby improving the pressing effect and quality of the shoe in the pressing cavity. At the same time, the two pressing cavities and two pressing mechanisms help improve the pressing efficiency of the shoe, meet the needs of mass pressing of shoes, and are highly practical.

[0041] The above description is merely a preferred embodiment of the present utility model and does not constitute any limitation on the technical scope of the present utility model. Therefore, any minor modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall still fall within the scope of the technical solution of the present utility model.
