Description

Technical Field

[0001] This utility model mainly relates to the field of glue injection equipment, specifically a glue injection device. Background Technology

[0002] A glue gun is a tool for applying glue, and it can be used wherever glue is needed. It is widely used in industries such as construction and decoration, electronics, automobiles and auto parts, shipbuilding and containers. In modern industrial processes, the frequency of glue gun use is extremely high due to the various construction environments. Workers need to pick up the glue gun multiple times for glue application. Moreover, the existing glue gun structure is generally a consumable replacement type, which requires changing the hot melt glue stick or glue reservoir multiple times during the glue application process. This is cumbersome, time-consuming, and labor-intensive, reducing glue application efficiency. In addition, glue guns need to be flexible in different working environments. Therefore, there is a need for a glue application device that can be picked up and used flexibly by humans at any time. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a glue dispensing device. Its main advantages are: by incorporating a glue gun structure suspended by a spring balancer, workers can easily access the glue gun for dispensing or applying glue; by further integrating a glue storage box and a glue pump to supply glue to the glue gun, the glue storage box allows for large-scale glue storage, avoiding frequent glue replacements; and by designing a rotatable and angle-adjustable connection between the glue storage box and the glue gun, the glue gun can be adjusted at different angles during operation, preventing the dispensing angle from being affected by pipe connections. Additionally, an electric heating structure is installed inside the glue gun to prevent the glue from hardening and affecting its use, and to prevent the movable structure from being stuck together by the glue.

[0004] To achieve the above objectives, this utility model employs the following technical solution:

[0005] A glue dispensing device includes a glue gun housing. A glue gun nozzle is fixedly disposed at the front of the glue gun housing and communicates with it.

[0024] Example: A glue dispensing device

[0025] like Figure 1-7As shown, a glue dispensing device has the following specific structure:

[0026] A glue dispensing device includes a glue gun housing 1. A glue gun nozzle 2 is fixedly mounted on the front of the glue gun housing 1 and communicates with it. A heating glue guide tube 3 is provided inside the glue gun housing 1 and communicates with the glue gun nozzle 2. Glue is guided to the glue gun nozzle 2 through the heating glue guide tube 3 for glue dispensing. Furthermore, the heating glue guide tube 3 can be used to heat the glue inside to prevent solidification. A glue guide tube support 4 is fixedly mounted inside the glue gun housing 1 and sleeved around the heating glue guide tube 3 for support. A bearing limiting ring 5 is fixedly mounted at the rear end of the heating glue guide tube 3. A rotating bearing 6 is sleeved around the outer periphery of the heating glue guide tube 3, and the inner ring of the rotating bearing 6 is fixedly connected to the bearing limiting ring 5. Next, a rotation adjustment tube 7 is fitted around the outer circumference of the outer ring of the rotating bearing 6, passing through the rear of the glue gun shell 1 and rotatably connected to it. A bearing limiting ring 8 is fixedly provided at the end of the rotation adjustment tube 7 and is fixedly connected to the outer ring of the rotating bearing 6. The rotation adjustment tube 7 is rotatably connected to the heating glue guide tube 3 through the rotating bearing 6. A flexible glue injection tube 9 is provided inside the rotation adjustment tube 7, inserted into the heating glue guide tube 3 and communicating with the glue gun nozzle 2.

A connecting tube 21 is fixedly provided at the rear of the rotating tube 20 and communicates with it. By injecting glue into the connecting tube 21, the glue further enters the rotating shaft glue box 17 through the rotating tube 20 and enters the glue box 12 on both sides through the glue inlet hole 2 18 and the glue inlet hole 13. Then, it enters the rotating adjustment tube 7 through the branch tube 11 and is further guided to the glue gun nozzle 2 position for glue injection through the flexible glue injection tube 9. The rotating shaft glue box 17 can be rotated to change its angle, so that the device can flexibly change its angle.

[0028] A glue gun handle 22 is fixedly provided on the rear bottom side of the glue gun housing 1. A glue gun wrench groove 23 is provided at the front of the glue gun handle 22. A glue gun wrench 24 is provided inside the glue gun wrench groove 23 and is rotatably connected to it. A spring rod 25 is provided inside the glue gun wrench groove 23 and is inserted into the glue gun wrench 24 and slidably connected to it.

[0029] A connecting ring 29 is fixedly provided on the upper rear side of the glue gun shell 1. A spring balancer 30 is connected to the connecting ring 29 for hoisting and pulling the glue gun shell 1. A vertical bracket 31 is fixedly connected to the rear of the spring balancer 30. A support plate 32 is fixedly provided at the bottom of the vertical bracket 31. A glue storage box 33 is provided at the rear of the support plate 32 for storing glue.

[0030] This solution also includes a controller, the location of which is set by the operator according to the actual situation during operation. The controller is used to control the electrical components used in this solution, including but not limited to sensors, motors, telescopic rods, water pumps, solenoid valves, heating wires, heat pumps, displays, computer input devices, switches, communication devices, lights, speakers, and microphones. The controller is an Intel processor, AMD processor, PLC controller, ARM processor, or microcontroller. It is used in conjunction with a motherboard, memory modules, storage media, and power supply, which is AC power or a lithium battery. When a display screen is provided, a graphics card is also included. For the operating principle of the controller, please refer to "Principles of Automatic Control," "Microcontroller Principles and Application Simulation Cases," and "Sensor Principles and Applications" published by Tsinghua University Press. Other books in this field can also be consulted. Other automation control and electrical components not mentioned are knowledge well known to those skilled in the art and will not be described in detail here.

[0031] Working principle:

[0032] In use, the glue gun housing 1 is first hoisted onto the upper part of the vertical support 31 by the spring balancer 30, allowing the glue gun housing 1 to be easily accessible. Then, by operating the glue gun lever 24, the stroke control bar 26 slides against the circuit board 27. The movement of the stroke control bar 26 is read, and a control signal is sent to the glue pump 34 via the control line 28. Depending on the movement of the stroke control bar 26, the glue pump 34 starts at different pumping speeds. The glue pump 34 then pumps the glue stored in the glue storage box 33 through the pumping port 36 into the connecting pipe 21. The glue then enters the rotating shaft glue inlet box 17 through the rotating pipe 20 and passes through the glue inlet hole 2 18 and glue inlet hole 13 into the glue inlets on both sides. The glue is fed into the glue inlet box 12, then enters the rotation adjustment tube 7 through the branch tube 11, and is further guided to the glue gun nozzle 2 position through the flexible glue injection tube 9 for glue injection. When it is necessary to change the angle of the glue gun nozzle 2, the rotation adjustment tube 7 is rotatably connected to the heating glue guide tube 3, so that the structure connected thereto can rotate, thereby changing the rotation angle of the glue gun shell 1. Furthermore, the glue inlet box 17 is installed in the sealing rotating shaft ring 15 for rotatable connection, so that the rotating tube 20 and the connecting tube 21 can rotate around the glue inlet box 12, thereby changing the angle between the connecting tube 21 and the glue gun shell 1. With the cooperation of the rotation structure, the glue gun shell 1 can be driven by the glue gun handle 22 to rotate in multiple directions, driving the glue gun nozzle 2 to different angles for operation, reducing the influence of the connecting tube 21 on the angle of the device.
