Synchronous feeding mechanism for tongue depressor machine

Abstract

The invention relates to a synchronous feeding mechanism for a tongue depressor machine, which comprises two paired rollers connected in rolling way and two feeding rollers; the lower paired roller is fixed; the roller shaft of the upper paired roller is mounted on a pre-tightening spring; the pre-tightening spring bears against a pushing block; the pushing block is mounted on the shell through screws and can be adjusted in position by the screws; a guide roller is arranged between the upper feeding roller and each of the two paired rollers; and the lower side of the guide roller and the lower side of the upper paired roller are located on the same horizontal height. The synchronous feeding mechanism for the tongue depressor machine provided by the invention has the beneficial effects that: feeding speeds of two material belts are adjusted by the pre-tightening spring to ensure that feeding speeds of two feeding rollers are completely the same. And pre-tightening force of the pre-tightening spring can be adjusted in real time according to different thicknesses, friction coefficients and feeding speeds of material belts, so that better synchronization effect is realized. While the stability of the paired rollers can be better ensured by the arrangement of a guide wheel and the tension force in other directions may not be acted on the paired rollers.

Description

technical field [0001] The invention relates to a synchronous feeding mechanism of a spatula machine, which belongs to the technical field of production equipment for commonly used spatulas of medical instruments. Background technique [0002] At present, tongue depressors only use more traditional production equipment. In this technical field, after searching, it was found that domestic technical websites could not find the newly developed technical information, including the official website of the State Intellectual Property Office, China Machinery Network, etc. Therefore, it can be generally believed that at present, at least domestic equipment manufacturers have invested less in the research and development of tongue depressors or simply engaged in the production of traditional equipment, but have not put forward good solutions for the technical problems existing in traditional equipment. solution. [0003] After many years of design and production experience of our t...

Problems solved by technology

[0004] The technical problem to be solved by the present invention is to overcome that the feeding mechanism of the existing tongue depressor uses two feeding rollers to feed separately, and in the process of thermoplastic packaging after the material tape is cut, it is easy to produce indentation, poor sealing, etc. problem, a synchronous feeding mechanism for a spatula machine is provided
