Adhesive dispensing jig

Abstract

An adhesive dispensing jig comprises a needle cylinder, a needle head, a nut, a positioning pin and an elastic element. A channel penetrating a body is formed inside the needle cylinder; a protruding portion is arranged at one end of the needle cylinder; the needle head is connected with the protruding portion of the needle cylinder and comprises two oppositely-arranged control portions and two oppositely-arranged matched portions; the matched portions are provided with threads; the two control portions and the two matched portions are spliced to form a runner in an assembling mode; the runner and the channel are through; the needle head is sleeved with the nut; threads on the inner side of the nut are matched with the threads of the matched portions; the positioning pin is arranged in the two control portions and the two matched portions in a penetrating mode; the elastic element is arranged in the two control portions; one end of the elastic element is connected with the positioning pin; and the other end of the elastic element is connected with the control portions. The jig is convenient to use; the diameter of the adhesive dispensing needle head can be manually adjusted; meanwhile, the adhesive dispensing jig is simple in structure and easy to manage and control; adhesive dispensing needle heads in various specifications are prevented from being purchased; and a large amount of cost is saved.

Description

【Technical field】 [0001] The invention relates to a glue dispensing fixture, in particular to a glue dispensing fixture whose diameter can be adjusted. 【Background technique】 [0002] In today's plastic industry, a large number of dispensing fixtures are used. Generally, during the dispensing process, the staff will choose dispensing needles with different diameters according to the diameter of the dispensing path. However, this way of working will bring certain defects: on the one hand, since various plastic products of different specifications and types must be purchased, it is necessary to purchase a variety of dispensing needles with different diameters, which consumes a lot of cost and a lot of The dispensing needles are not easy to manage; on the other hand, the size of the dispensing path of some plastic products cannot match the diameter specifications of the existing dispensing needles, which will also cause unsatisfactory dispensing effects. [0003] In view of th...
