Description

Technical Field

[0001] The utility model relates to the technical field of textiles, in particular to a fixed-length cutting device for low-elastic rubber bands. Background Art

[0002] Cutting means cutting and chopping. In the processing industry, the product is disconnected according to the size requirements. In textile production enterprises, rubber band is one of the materials frequently used. Rubber bands are divided into high elasticity and low elasticity according to their elasticity. Low elastic rubber bands often need to be cut to a fixed length during the production process. Cutting requires a cutting device to cut the rubber band. The cutting length of the existing cutting device cannot be measured, resulting in inaccurate cutting of the rubber band, reducing the practicality of the cutting device, which is not convenient for the production needs of the enterprise. In addition, many cutting devices only have a single cutting device, and the cutting efficiency is low, which often cannot meet the production needs of the enterprise. In view of this, the inventor proposes a fixed-length cutting device for low-elastic rubber bands. By arranging multiple low-elastic rubber band conveyor belts on the device and providing a cutting device in the middle of the conveyor belt, the low-elastic rubber bands can be cut in batches, and can also be cut according to different length requirements, thereby improving the practicality and cutting efficiency of the device and meeting the production needs of the enterprise.

[0003] In order to improve the accuracy and stability of the elastic cutting device, a Chinese patent (authorization announcement number: CN208826766U) discloses an elastic cutting device for diaper production with measurable length. The utility model includes a box body, the top of the box body is fixedly connected to the cutting device body, the left side of the top of the box body is provided with a first movable groove, the bottom of the inner wall of the first movable groove is slidably connected with a sleeve, the top of the sleeve extends to the top of the box body, the top of the sleeve is provided with a press block, and the bottom of the press block is fixedly connected with a vertical rod. The utility model solves the problem that the existing cutting device cannot measure the cutting length, resulting in inaccurate cutting of the elastic band, by setting the box body, the cutting device body, the first movable groove, the sleeve, the press block, the vertical rod, the fixed plate, the horizontal plate, the clamping block, the movable plate, the spring, the horizontal rod, the groove, the connecting plate, the ruler and the workbench. The utility model has the advantage of measurable length and improves the practicality of the cutting device.

[0004] This solution still has some shortcomings in application. Due to the large production demand of the enterprise, if a device that cuts off the monomers one by one is used, it is easy to have low cutting efficiency and cannot meet the production needs of the enterprise. At the same time, the collection of low-elastic rubber bands after cutting also needs to be quick and simple, and manual intervention should be reduced as much as possible, otherwise it will affect the overall cutting efficiency and increase the labor intensity of workers. Therefore, it is necessary to improve the structure of the drive device so that it has higher cutting efficiency and improves the level of automation while ensuring accuracy. Utility Model Content
