Description

Technical Field

[0001] This utility model relates to the field of edge sealing glue gun technology, specifically a polyurethane edge sealing glue gun anti-clogging device. Background Technology

[0002] A polyurethane edge banding gun is a tool specifically designed for polyurethane (PUR) edge banding adhesive and used in the edge banding process of boards. PUR edge banding technology uses moisture-curing reactive polyurethane hot melt adhesive. The adhesive is liquefied by heating, applied to the edge banding tape or the edge of the board, and then pressed together. Under the action of moisture in the air, it undergoes a chemical reaction and cures, forming high-strength chemical bonds.

[0003] Regarding the above and existing related technologies: edge sealing guns are a common edge sealing tool. Manual polyurethane edge sealing guns often require the glue tube to be installed on the gun. Due to the cold weather in some areas, polyurethane is prone to insufficient fluidity in low-temperature environments, which can easily lead to condensation and blockage of the outlet. Therefore, a polyurethane edge sealing gun anti-clogging device is proposed to address the above problems. Utility Model Content

[0004] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0005] The technical solution adopted by this utility model to solve its technical problem is as follows: The polyurethane sealing glue gun anti-clogging device of this utility model includes a gun body, a heating lamp and a fixing device. A glue tube is inserted into the inner surface of the gun body, and the heating lamp is located directly above the glue tube. The fixing device is set on the surface of the gun body and the heating lamp. The fixing device includes a fixing strip. The side wall of the fixing strip is fixedly connected to the surface of the gun body. A rotating frame is rotatably connected to the surface of the fixing strip. The heating lamp is inserted into the inner surface of the rotating frame. A threaded post is threadedly connected to the inner wall of the rotating frame. A top block is rotatably connected to the side wall of the threaded post. The surface of the top block is slidably connected to the inner surface of the rotating frame. The threaded post drives the top block to move. The top block presses against the side wall of the heating lamp and then pushes the rotating frame to rotate on the surface of the fixing strip. The heating lamp is aligned with the glue tube for heating. By setting the fixing strip, the rotating frame, the threaded post and the top block, the position of the heating lamp can be fixed, thereby facilitating the heating of the glue tube.

[0006] Preferably, the top block has two sliding columns fixedly connected to its side wall. The surfaces of the two sliding columns are slidably connected to the inner wall of the rotating frame. The sliding columns slide on the inner wall of the rotating frame, and the top block can be supported by the sliding columns.

[0007] Preferably, the sidewalls of the two sliding columns are fixedly connected to a connecting block, the inner wall of the connecting block and the surface of the threaded column are rotatably connected, and when the threaded column rotates, the threaded column rotates on the inner wall of the connecting block, and the connecting block can restrict the position of the sliding column on the inner surface of the rotating frame.

[0008] Preferably, two support blocks are fixedly connected to the surface of the gun body. The two support blocks are located directly below the rotating frame. When the rotating frame rotates, the rotating frame rotates to the upper surface of the support blocks, and the support blocks can support the rotating frame.

[0009] Preferably, a fixing block is fixedly connected to the surface of the rotating frame near the support block, and a positioning pin is threadedly connected to the inner wall of the fixing block and the support block. The positioning pin is rotated to the inner wall of the fixing block and the support block, and the positioning pin and the fixing block can limit the position of the rotating frame.

[0010] Preferably, the surface of the rotating frame is provided with two limiting devices, each including two movable columns. The surfaces of the two movable columns are slidably connected to the inner wall of the rotating frame. The side walls of the two movable columns are fixedly connected with locking strips, which are fitted onto the surface of the heating lamp. The end of the movable column away from the locking strip is fixedly connected to a limiting plate. The movable column drives the locking strip to slide, and the locking strip is fitted onto the surface of the heating lamp. By setting the movable columns, locking strips, and limiting plate, the position of the heating lamp can be limited.

[0011] Preferably, the side wall of the limiting plate and the side wall of the rotating frame are fixedly connected with springs. When the limiting plate is released, the spring rebounds and can drive the limiting plate to move, while also limiting the position of the limiting plate.

[0012] Preferably, a through hole is provided on the surface of the rotating frame near the moving column, and the surface of the moving column and the inner wall of the through hole of the rotating frame are slidably connected. When the moving column slides, the moving column slides on the inner wall of the through hole, and the opening of the through hole can facilitate the movement of the moving column.

[0013] The advantages of this utility model are:

[0014] 1. When heating the hose is required, this utility model pushes the rotating frame to rotate on the surface of the fixed strip. The rotating frame drives the fixed block to rotate, and the rotating frame and fixed block rotate onto the support block. Then, the positioning pin is rotated to the inner wall of the fixed block and support block. The heating lamp is then inserted into the inner surface of the rotating frame. The threaded column is then rotated to rotate on the inner wall of the rotating frame. The threaded column drives the top block to move, and the top block drives the sliding column to slide. The sliding column slides on the inner wall of the rotating frame and drives the connecting block to move. After the heating lamp is fixed, the heating lamp is turned on to heat the hose. The hose can be used after it reaches a suitable temperature. By setting the entire device, the hose can be heated, reducing the possibility of hose blockage and also reducing the possibility of hindering hose disassembly and assembly.

[0015] 2. When installing the heating lamp, this utility model involves pulling the limiting plate to make the limiting plate move the moving column. The moving column slides on the inner wall of the through hole. When the moving column slides, it will move the locking strip. The limiting plate will also cause the spring to stretch. After the locking strip moves to the appropriate position, the heating lamp is pushed to move to the appropriate position. When the limiting plate is released, the spring will rebound. The spring drives the limiting plate, the moving column and the locking strip to move. The locking strip moves to the surface of the heating lamp. By setting the entire device, the position of the heating lamp can be restricted, reducing the situation of the heating lamp moving randomly. Attached Figure Description
