[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Example 1:

[0028] like Figures 1 to 4 As shown, this embodiment provides a constant pressure spray adhesive pressure tank, comprising: a pressure tank assembly 1, including an adhesive carrying structure 11, which is disposed on the ground, the adhesive carrying structure 11 including an adhesive storage tank 113, the top of the adhesive storage tank 113 being provided with a cover plate 12; a fixing assembly 2, including clamping screw blocks 21, which are disposed on the cover plate 12 in four groups; a pressure conveying assembly 3, including an air inlet pipe 34, which penetrates the cover plate 12 for inputting gas; and an adhesive inlet valve 4, which penetrates the cover plate 12 for inputting adhesive.

[0029] In this embodiment, the pressure tank assembly 1, the fixing assembly 2, and the pressure conveying assembly 3 constitute the constant pressure spraying adhesive pressure tank involved in this application, realizing a constant pressure spraying adhesive pressure tank.

[0030] In this embodiment, the glue storage tank 113 is typically made of metal, possessing a certain strength and corrosion resistance, capable of withstanding the pressure and weight of the glue liquid, and used to store various glues and adhesives. The glue storage tank 113 is generally existing technology, belonging to commonly known technology in the field; it is used without modification, therefore its connection method is not described in detail.

[0031] In this embodiment, the connection between the air intake pipe 34 and the external pressure tank is provided with a quick connector made of metal, which facilitates disassembly and installation.

[0032] It should be noted that after the glue inlet valve 4 is opened, the glue can flow from the glue delivery pipe into the glue storage tank 113, completing the glue loading. After the four sets of clamping screws 21 of the fixing assembly fix the cover plate 12 to the glue storage tank 113, the cover plate 12 fits tightly against the glue storage tank 113, achieving a seal and preventing glue leakage. The pressure delivery assembly 3 is connected to an external pressure tank through the air inlet pipe 34. After opening, gas enters the pressure tank, pressurizing the glue inside and ensuring that the glue can be smoothly output from the glue outlet valve 4.

[0033] Specifically, the pressure tank assembly 1 also includes: a viewing port 111, located on one side of the glue storage tank 113, for observing the internal working conditions of the glue storage tank 113; a glue dispensing valve 112, extending through one side of the glue storage tank 113 and located below the viewing port 111; a sealing gasket 13, installed between the glue storage tank 113 and the cover plate 12; and four sets of bayonets 121, located on the cover plate 12.

[0034] In this embodiment, during the operation of the pressure tank, the viewing port 111 allows the operator to check the remaining amount of glue in the tank, the flow status of the glue, and whether any impurities have entered, facilitating timely detection of problems and taking appropriate measures. The glue dispensing valve 112 connects to an external glue gun for glue spraying operations. The sealing gasket 13, made of rubber, is installed between the glue storage tank 113 and the cover plate 12 to prevent gas and glue leakage and ensure stable pressure inside the tank. The bayonet 121, in conjunction with the fixing component 2, is tightened by the clamping screw 21, ensuring a tight connection between the cover plate 12 and the glue storage tank 113, guaranteeing the sealing and stability of the pressure tank.

[0035] Specifically, the glue dispensing valve 112 is connected to an external glue gun for dispensing glue.

[0036] As a preferred implementation, after the glue in the pressure tank is pressurized, the glue dispensing valve 112 is opened, and the glue flows into the glue gun along the pipe connected to the glue gun under the action of the gas pressure in the tank, which is convenient for the operator to use.

[0037] Example 2:

[0038] Based on Embodiment 1, in order to fix the glue storage tank 113 and the cover plate 12, a fixing component 2 is provided on the glue storage tank 113.

[0039] Specifically, the fixing component 2 also includes: a screw 22, which is threadedly connected to and passes through the clamping screw block 21, and the bottom end of the screw 22 is hinged to a groove opened at the top of the glue storage tank 113.

[0040] It should be noted that when installing the cover plate 12, the screw 22 is inserted into the hinge groove at the top of the glue storage tank 113, and then the cover plate 12 is put on, aligning the screw 22 with the snap-fit ​​121 on the cover plate. The operator manually rotates the tightening screw block 21. Since the screw 22 is threadedly connected to the tightening screw block 21, the screw 22 will gradually move downwards, firmly fixing the cover plate 12 to the glue storage tank 113, thus achieving a firm fixation of the cover plate and the glue storage tank, ensuring the sealing and stability of the pressure tank during pressurization and use.

[0041] Specifically, when the cover plate 12 covers the glue storage tank 113, the screw 22 is set in the bayonet 121, and the clamping screw block 21 is attached to the top of the cover plate 12 to lock the cover plate 12 and the glue storage tank 113.

[0042] As a preferred implementation, during the installation process, the cover plate 12 is placed on the glue storage tank 113, and the screw 22 is accurately placed into the bayonet 121. Then, the clamping screw block 21 is rotated to fit the top of the cover plate 12, fixing the cover plate 12 and the glue storage tank 113 together to form a sealed connection. This ensures that the internal gas and glue will not leak when the pressure tank is working normally, and that it can withstand a certain pressure, ensuring the stable operation of the pressure tank.

[0043] Example 3:

[0044] Based on Example 2, in order to monitor and adjust the pressure inside the glue storage tank 113, a pressure gauge 31 is installed on the cover plate 12 and an regulating valve 33 is installed on the air inlet pipe 34.

[0045] Specifically, the pressure transmission assembly 3 also includes: a pressure gauge 31, which is fixedly arranged on the cover plate 12 and used to detect the internal pressure of the glue storage tank 113; a safety valve 32, which is located between the air inlet pipe 34 and the pressure gauge 31; and a regulating valve 33, which is located on the air inlet pipe 34 and used to regulate the gas input.

[0046] It should be noted that the pressure gauge 31 monitors the pressure inside the storage tank in real time, allowing operators to check the pressure at any time. When gas is introduced through the inlet pipe 34, operators can use the regulating valve 33 to control the gas flow into the pressure tank, thereby regulating the pressure inside the tank. The safety valve 32 serves as a safety protection mechanism. When the pressure inside the tank exceeds the set safety value, the safety valve 32 automatically opens to release excess gas, preventing damage to the pressure tank due to excessive pressure and ensuring the safety of equipment and personnel.

[0047] Specifically, the air inlet pipe 34 is connected to the external pressure tank, and the glue inlet valve 4 is connected to the pipeline for conveying the glue.

[0048] In this embodiment, when the pressure tank is working, the pressure supply device is turned on, and the air inlet pipe 34 introduces pressurized gas from the external pressure tank body. The glue is introduced in conjunction with the glue inlet valve 4 to realize the storage and pressurization of glue in the pressure tank.

[0049] In use, when the pressure tank is to be used, the user connects the pipe for delivering the adhesive to the inlet valve 4 to send the adhesive into the storage tank 113. The external glue gun is connected to the outlet valve 112, and the adhesive in the storage tank 113 enters the external glue gun through the outlet valve 112. The viewing port 111 allows observation of the adhesive usage. The user connects the external pressure tank to the air inlet pipe 34, and the pressure gauge 31 detects the internal pressure of the storage tank 113. The safety valve 32 enhances safety. The regulating valve 33 controls the pressure output. This controls the speed at which the glue dispensing valve 112 outputs the glue. When cleaning the inside of the glue storage tank 113, the clamping screw 21 is turned to release the pressure of the clamping screw 21 on the cover plate 12, so that the cover plate 12 can be removed from the glue storage tank 113 for cleaning. After cleaning, the cover plate 12 is put back on, and the clamping screw 21 is turned again to press the clamping screw 21 onto the cover plate 12, thus fixing the cover plate 12 back onto the glue storage tank 113. The sealing gasket 13 acts as a gas seal.

[0050] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
