Description

Technical Field

[0001] This utility model belongs to the field of interior decoration technology, specifically relating to an edge seam glue injection device. Background Technology

[0002] When applying caulking gun to seams during interior decoration, the residual caulking gun tends to solidify gradually, causing blockages. Although the caulking gun can be squeezed out promptly after use, a certain amount of caulking gun will still remain at the nozzle. After solidification, workers need to use a cleaning needle to pick out the solidified caulking gun bit by bit when using it again, which is inconvenient for workers and affects the construction progress. Utility Model Content

[0003] In order to overcome the shortcomings of the prior art, the purpose of this utility model is to provide a seam glue injection device to solve the problems mentioned in the background art.

[0004] The technical solution adopted by this utility model to solve its technical problem is as follows:

[0005] A seam glue injection device is provided, including a glue gun tube and a glue gun head. The glue gun head is fixedly installed on one side of the glue gun tube, and a slide rod is fixedly installed at the tail of the glue gun tube. A slip ring is installed on the slide rod, and a motor is fixedly installed on the slip ring. A column is fixedly installed at the output end of the motor. A groove is formed on the column, and an electric brake is provided in the groove. A first nut is fixedly installed in the middle part of the tail of the glue gun tube. A first screw is threaded on the first nut. One end of the first screw is located in the electric brake, and a piston is rotatably installed at the other end of the first screw through a bearing. A through hole is formed on the piston, through which the first screw is inserted. A push rod is provided in the through hole. A placement hole is formed at the end of the push rod located in the through hole. A second screw is provided in the placement hole. A second nut is installed on the second screw. The second nut is fixedly connected to the push rod. The second screw is fixedly connected to the inner wall of the groove. A sliding groove is provided in the through hole, and a slider is provided in the sliding groove. The slider is fixedly connected to the second nut.

[0006] Furthermore, a first contact switch is fixedly installed on the slide bar, and the first contact switch is connected to the electric brake via a circuit.

[0007] Furthermore, a second contact switch is provided in the slide groove, and the second contact switch is connected to the electric brake through a circuit.

[0008] Furthermore, a handle is fixedly installed on the glue gun tube.

[0009] Furthermore, a switch is fixedly installed on the handle.

[0010] Furthermore, the handle contains a storage battery.

[0011] Furthermore, a glue tube is fixedly installed on the glue gun tube, and a feed hole is opened on the glue tube to penetrate the glue gun tube. A one-way valve is fixedly installed in the feed hole.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model provides an edge seam glue injection device. In use, the glue gun head is blocked, and the motor is started to drive the first screw to rotate forward, causing the piston to move to the right, putting glue into the glue tube. The glue is then drawn into the glue gun tube through the glue tube. Subsequently, the motor is controlled to drive the first screw to rotate in the opposite direction, causing the piston to move to the left, discharging the glue from the glue gun head for edge seam glue injection. After glue injection is completed, the slip ring continues to move with the motor to completely discharge the glue from the glue gun tube. The electric brake is then released from fixing the first screw, allowing the motor to drive only the second screw to rotate independently. The rotation of the second screw... The second nut and the push rod move to the left along the second screw, inserting the push rod into the glue gun head and pushing out the glue. Then, the motor is controlled to rotate forward again, driving the second screw to rotate, causing the second nut and the push rod to move to the right along the second screw. The push rod retracts, and the electric brake is activated to fix the first screw. At this time, the first screw and the second screw rotate synchronously, and the push rod stops moving, facilitating normal use next time. This device facilitates glue injection operations and allows for cleaning of the glue gun head after use, preventing glue from solidifying inside the glue gun head and affecting subsequent use.

[0014] 2. In the example of this utility model, when the slip ring contacts the first contact switch, the first contact switch can control the electric brake to release the fixation of the first screw, so that the second screw can rotate independently.

[0015] 3. In the example of this utility model, when the slider contacts the second contact switch, the second contact switch can control the electric brake to start fixing the first screw, so that the first screw can rotate again.

[0016] 4. The edge seam gluing device of this utility model example has a handle that makes it easy to hold.

[0017] 5. An example of this utility model is a seam gluing device, which allows for convenient control of the motor's on / off state and forward / reverse rotation via a switch.

[0018] 6. The edge seam gluing device of this utility model can conveniently supply power to the motor and electric brake through a storage battery.

[0019] 7. In the example of this utility model, a seam glue injection device can be used by blocking the glue gun head, allowing glue to be drawn into the glue gun tube through the glue tube. Attached Figure Description
