Cow leather stretcher

Abstract

The invention relates to the technical field of stretcher equipment, and discloses a cow leather stretcher. The cow leather stretcher comprises a bottom plate, wherein the top of the bottom plate is sequentially and fixedly connected with a right stand column and a left stand column from right to left, a downward pulling device is arranged on one side of the left stand column, the downward pullingdevice comprises a main motor, an output shaft of the main motor is fixedly connected with a main rotating shaft, a conical gear is arranged at the top of the main rotating shaft, and a driving rod is arranged on one side of the conical gear. According to the cow leather stretcher, the downward pulling device, a pull plate and a hook are arranged, so that the main motor is used for driving the driving rod to rotate, and then a first rotating rod is rotated; a second rotating rod is driven to move up and down under the action of a movable rod through rotation of the first rotating rod, then the pull plate on one side of a fixing block is driven to move up and down in a sliding groove so as to stretch a cow leather ring between the pull plate and the hook, and the action force on the lowerpart of the cow leather ring is uniform, so that the purpose of up-and-down reciprocating stretching is achieved; and mechanical production is achieved, so that the production efficiency is greatly improved, and the production cost is reduced.

Description

technical field [0001] The invention relates to the technical field of stretching machine equipment, in particular to a cowhide stretching machine. Background technique [0002] Cowhide is the epidermis of animal cattle. Because the cortex is fine and durable, it is often used in handicrafts. In the traditional cowhide process, the skin after drying is reduced in size and hard, so the process of softening is also very important. This process uses mechanical methods. , if it falls soft, etc., the leather can also be stretched around on the stretcher, so that the leather can be stretched as much as possible to increase the leather retention rate, and the preparation of the strip-shaped cowhide needs to be repeatedly beaten to enhance the toughness of the leather. Traditional The production of hand-made strips of cowhide is processed by beating strips of cowhide with wood, which requires manpower to beat, which consumes a lot of manpower, takes a long time, and costs a lot, or ...
