Cam-driven last stripping machine

Abstract

The invention provides a cam-driven integrated machine for taking off the last and inserting the last into the last, which belongs to the field of shoe-making equipment, and includes a fixed frame on which an inverted shoe last is fixed, a flattening component is arranged on the top of the shoe last, and the left and right sides of the shoe last There is a clamping component on the side, and a stripping component at the rear end of the shoe last. The stripping component includes a rising cam, a rising driving rod and a lifting frame. The rising cam is rotatably connected to the fixed frame, and the first driving groove is provided on the rising cam. , the first drive groove drives the lifting frame to move up and down through the rising driving rod. The upper end of the lifting frame is provided with a translation cam, a translation driving rod and a last block. The translation cam is arranged horizontally and connected with the lifting frame in rotation. The drive groove, the second drive groove drives the last block to move left and right through the translation drive rod. The power drive of the present invention makes the operation of the whole structure more stable and reliable, the failure rate is greatly reduced, energy consumption is reduced, energy is saved, and the environment is more environmentally friendly.

Description

technical field [0001] The invention belongs to the field of shoe-making equipment and relates to a cam-driven integrated machine for taking off the last and inserting the last. Background technique [0002] Shoe last, a traditional Chinese shoemaking utensil, also known as last, is popular in most parts of the country. The wooden product is cut into the shape of the foot and filled in the shoe to fit the foot. The shoe last is the matrix of the shoe and the molding mold of the shoe. The shoe last not only determines the shape and style of the shoe, but also determines whether the shoe fits and protects the foot. Therefore, the design of the shoe last must be based on the shape of the foot, but it cannot be the same as the shape of the foot, because the shape, size, stress, etc. of the foot change when the foot is at rest or in motion. , the performance of raw and auxiliary materials, and the wearing environment and conditions are also different. The shape of the shoe last...

Problems solved by technology

[0003] At present, the production of shoe lasts is made by mechanical processing, and the strength is stable and can be reused. However, at present, a specific shoe last is specified for a shoe size and shoe shape. The higher the accuracy and shape requirements of the last, the higher the processing accuracy and difficulty, the higher the cost, but the trend of people's aesthetics changes rapidly, and the replacement of shoe lasts is also very fast, which has resulted in the replacement of a large number of shoe lasts, cost Increase

[0004] The process of making shoes involves lasting and taking off the last. The lasting completes the processing of the shoe body, and after the shoe body is finished, it involves taking off the last. The machines currently on the market generally only involve the lasting or only the lasting. There are few structures that integrate the lasting and lasting into one, and at present, on the market, no matter whether it is a lasting machine or a lasting machine, all drives are completed by air cylinders, which need to be equipped with air pumps to ensure stable air flow. The setting of the air source and air pump needs a lot of energy, and if the air source is unstable, it is easy to cause improper movement and affect the stability of the entire structure.
