Material injection gun head position adjusting device and method

Abstract

The invention discloses a material injection gun head position adjusting device, and relates to the technical field of refrigerator foaming. The device comprises a fixing ring; an adjusting rod is hinged to one side of the fixing ring; the side wall of the fixing ring is slidably connected with an adjusting block; the outer wall of the fixing ring is connected with a plurality of spring pieces; the spring pieces are connected with clamping blocks; a straight notch is formed in the side face of the adjusting rod; the adjusting rod is connected with a mounting block; a mounting sleeve in clearance fit with the straight notch is fixed on the mounting block; laser positioning lamps are arranged at two ends of the mounting sleeve; a nut is in threaded connection with the outer wall of the mounting sleeve; a guide column matched with the straight notch is fixed on the adjusting block; an outer arc-shaped plate and an inner arc-shaped plate which are matched with the fixing ring are fixed tothe side face of the adjusting block; and the outer arc-shaped plate is connected with a hand-screwed nut. The fixing ring is fixed to a main material gun head through the clamping blocks, the positions are determined through the two laser positioning lamps, position adjustment of the material injection gun head and a material injection opening is achieved, and the problems that an existing material injection gun head is low in position adjustment efficiency and precision, and potential safety hazards exist in manual operation are solved.

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.
