A device and method for adjusting the position of the injection gun head

Abstract

The invention discloses a device for adjusting the position of a filling gun head, and relates to the technical field of refrigerator foaming. The invention comprises a fixed ring; one side of the fixed ring is hinged with an adjusting rod; the side wall of the fixed ring is slidably connected with an adjusting block; the outer wall of the fixed ring is connected with several spring pieces; the spring piece is connected with a block; The adjusting rod is connected with a mounting block; the mounting block is fixed with a mounting sleeve that fits with the straight slot; both ends of the mounting sleeve are provided with laser positioning lights; the outer wall of the mounting sleeve is threaded with a nut; the adjusting block is fixed with a mounting sleeve that fits with the straight slot The guide column; the side of the adjustment block is fixed with an outer arc plate and an inner arc plate adapted to the fixing ring; the outer arc plate is connected with a thumb nut. The invention fixes the fixed ring on the head of the main material gun through the clamping block, and determines the position through two laser positioning lights, so as to realize the position adjustment of the injection gun head and the injection port, which solves the problem of the existing position adjustment of the injection gun head The efficiency and precision are low, and there are potential safety hazards in manual operation.

Description

technical field [0001] The invention belongs to the technical field of refrigerator foaming, and in particular relates to a device for adjusting the position of a filling gun head and a method thereof. Background technique [0002] Box foaming is an essential process in the process of making refrigerators. Generally speaking, a filling port (usually a circular hole with a diameter of 36mm) is opened at the bottom of the box or other positions, and the injection gun head (gun head) The outer diameter is generally 32mm) into the injection port, and the foaming material is injected into the box to be foamed through the injection gun head, and then the foaming process is completed. Since the gap between the gun head with an outer diameter of 32mm and the injection port with a diameter of 36mm is small, it is necessary to precisely control the relative position between the injection gun head and the injection port. If there is a deviation, it is easy to cause the injection gun h...

Problems solved by technology

[0005] The purpose of the present invention is to provide a device for adjusting the position of the injection gun head. The fixed ring is fixed on the main material gun head by a block, and the position is determined by two laser positioning lights to realize the adjustment of the injection gun head and the injection port. It solves the problem of low efficiency and precision of the position adjustment of the existing injection gun head and potential safety hazards in manual operation.
