Problems solved by technology

This test method is relatively simple and fast, but there are some problems: (1) During the test process, two hands are required to operate at the same time, squeeze and time at the same time. If the hands are not synchronized, it will cause a large error, and the test results of different people There will also be deviations; (2) If the room temperature is inconsistent with the set temperature during the test, the temperature of the rubber material is likely to change during the test process, resulting in changes in the fluidity of the rubber material, making the test results inaccurate; (3) due to loosening of the hand After the trigger, there is still residual pressure in the rubber cartridge, and after the timing is stopped, there will still be a small amount of glue overflowing from the nozzle, resulting in inaccurate test results; (4), because the conventional rubber cartridge and piston are inconvenient to disassemble and clean after use, a disposable Yes, it is thrown away after the test, and in order to ensure the accuracy of the test results, imported disposable rubber cartridges with high precision are often used, which leads to higher costs and pollutes the environment
In this patent, the temperature of the rubber in the glue gun can be adjusted more conveniently, but it is still difficult to simultaneously squeeze and accurately time when used to test the extrusion speed, and there will be residual pressure after the test that will cause glue overflow, and it is inconvenient to disassemble and clean, etc. question

Embodiment 1

[0029] Such as Figures 1 to 4 As shown, a pneumatic glue gun assembly that is easy to clean includes a glue gun and a glue cartridge, and the glue gun includes a glue gun body 1, a glue gun handle 2, and a trigger 3; the front end of the glue gun body is provided with a front cover 4, and the rear end A rear end cover 5 is provided, and both the front end cover and the rear end cover are connected to the glue gun body through threads; the glue gun handle 2 is provided with an air inlet 6, and the glue gun handle 2 is provided with a valve that cooperates with the trigger 3 to control the on-off of the gas. Air valve mechanism 7; the air outlet 8 of the air valve mechanism 7 is connected to the joint on the rear end cover 5 through the glue gun air pipe 9; the rubber cartridge includes a rubber cylinder body 10, a piston 11, and a glue nozzle 12; the piston 11 A baffle 23 is arranged on the top, and the baffle 23 forms a cavity with the piston 11. The baffle 23 is also provide...

Embodiment 2

[0033] Compared with Embodiment 1, the glue gun assembly of this embodiment further includes a threaded plug 22 for sealing the glue outlet at the front end of the barrel 10 . The mouth of the tail of the barrel 10 is provided with external threads, and the glue gun assembly also includes a threaded sealing cover 21 for sealing the mouth of the tail.

[0034] The cylinder body of the rubber cartridge in this embodiment can be completely sealed by the rear sealing cover and the plug, can be heated and cooled, and will not leak glue or enter water. The schematic diagram of the rubber cartridge when sealing is as follows Figure 5 shown.

Abstract

The invention provides a pneumatic glue gun assembly convenient to clean. The pneumatic glue gun assembly comprises a pull rod with a brush and a baffle piece; a cavity and a baffle are designed in apiston of a glue cylinder; a sliding groove is formed in a glue gun body, a trigger extends from the position below a glue gun to the position above the glue gun, and the part, above the gun, of a trigger is hinged to one end of a connecting rod; the other end of the connecting rod can slide in the sliding groove and is hinged to one end of a bent rod, an arc-shaped gasket is arranged at the otherend of the bent rod and the arc-shaped gasket is used for blocking a glue nozzle; a timer is arranged on a glue gun handle; and a pressure sensor is arranged at the contact point between the triggerand an air valve mechanism, and the pressure sensor is connected to the timer. According to the pneumatic glue gun assembly, the piston can be pulled out easily through the pull rod and the glue cylinder is cleaned, and the glue cylinder is repeatedly used; after the glue injection is finished, the trigger is released, then the glue nozzle is automatically blocked , so that glue overflowing is prevented; the timer is controlled by the trigger, so that convenience and accuracy are achieved; and the extrusion speed under different pressures can be tested.

Description

technical field [0001] The invention belongs to the technical field of glue gun devices, and in particular relates to an easy-to-clean pneumatic glue gun assembly. Background technique [0002] Process steps such as injection or extrusion and mixing are often used in the processing of high-viscosity rubber or paste. Usually, if a raw material is replaced during the processing of these equipment, it is necessary to re-adjust the machine. After multiple adjustments, a suitable one can be determined. Injection process, including debugging of process parameters such as pressure and temperature. In the process of adjusting the machine, not only a lot of materials, manpower and time are wasted, but also the adjustment may fail, because the fluidity and viscosity parameters of the raw material are not suitable for processing with the current equipment. Therefore, usually before adjusting the machine, it is necessary to test the viscosity and fluidity of the raw material. For paste...
