Description

Technical Field

[0001] The utility model relates to the field of shoe machines, in particular to a sole pressing machine which is easy to open and close. Background Art

[0002] After the raw materials are cut, sewn and stretched, they have the prototype of shoes, and then they are made into shoes after the upper and sole are bonded. Upper and sole bonding is the process of bonding the outer sole, the upper foot and the insole after the upper is stretched with adhesive. The process of combining the upper and the sole is a major process in the shoemaking process. There are many ways to combine the upper and the sole. Adhesion, vulcanization, molding, injection, and seam are the five basic processes (therefore, semi-automatic equipment is generally used to cooperate with staff for processing). Among them, the viscose process is the most commonly used one in the market. A simple understanding is that after the outsole is placed in the lower mold, the upper with the shoe last is placed on the upper wall of the outsole, and then pressure is applied to make the two fit together.

[0003] Existing sole pressing machines generally use a pivoting upper cover with a flip structure. However, in actual processing, it is found that although the flip cover structure can be opened and closed quickly, its opening and closing degree is small, which affects the insertion and alignment of the staff, and requires bending over when using it. When the working time is long, it will affect the waist comfort of the staff. Utility Model Content

[0004] The main purpose of the utility model is to provide a sole pressing machine that is easy to open and close, aiming to improve the opening and closing degree of the existing sole pressing machine, facilitate the precise placement of the workers, reduce work fatigue, and improve processing stability.

[0007] A guide frame, wherein the bottom end of the guide frame is arranged at a position of the bottom mold away from the receiving groove, and the top end of the guide frame is provided with a top seat;

[0008] The upper cover is arranged on the guide frame and can slide vertically along its height direction. The top seat is provided with a first driving device, and the first driving device is used to drive the upper cover to move vertically.

[0009] In the actual design, vertical sliding can be achieved through the cooperation of the guide frame and the upper cover, so that a larger opening and closing degree can be achieved between the upper cover and the bottom mold, which is convenient for the staff to observe the receiving groove, make the upper and the sole more accurately aligned, and ensure the stability of the pressing; at the same time, the lower wall of the upper cover can facilitate the installation and adjustment of the pressing rod and the shoe upper covering structure, thereby improving the applicability of the sole pressing machine, improving production efficiency and convenience of use.
