Description

Technical Field

[0001] This utility model relates to the field of glue gun technology, and in particular to a multi-purpose foam glue gun with a cleaning function. Background Technology

[0002] Polyurethane foaming agents are a product of the cross-combination of aerosol technology and polyurethane foam technology. They are produced in both tube and gun types, exhibiting a sponge-like state. Foaming agents used in the production of microporous foam plastics are generally classified into two types: physical and chemical. This classification is based on whether the gas generation is a physical process (i.e., volatilization or sublimation) or a chemical process (i.e., the destruction of chemical structures or other chemical reactions). The full name of polyurethane foaming agent is single-component polyurethane foam sealant, commonly known as foaming agent, foaming adhesive, or PU sealant. The English term PU FOAM is a product of the cross-combination of aerosol technology and polyurethane foam technology. It is a special polyurethane product that contains polyurethane prepolymer, foaming agent, catalyst, and other components in a pressure-resistant aerosol can. When the material is sprayed from the aerosol can, the foamy polyurethane material rapidly expands and reacts with moisture in the air or the substrate it comes into contact with to form foam.

[0003] Currently, a search reveals a polyurethane sealant gun with patent number (CN202321099416.4) that can be used in both directions. The gun includes a gun with a barrel at its front end and a nozzle at the end of the barrel. A reverse adapter and a forward adapter are respectively located on the upper and lower sides of the barrel's sidewall, both connected to the barrel. A control valve is provided between each adapter and the barrel. A connecting post is located within each adapter, and a leak-proof mechanism is provided within each post. By providing the reverse and forward adapters on the upper and lower sides of the barrel's sidewall, sealant cartridges can be installed at both ends of the barrel. After installing the cartridges, the corresponding control valves are opened, allowing the selection of the cartridge's installation position according to the sealant application needs, making it convenient to use.

[0004] However, existing foam glue guns have a limited function, only able to spray foam glue alone. If a drying agent is to be sprayed, a different set of glue bottles needs to be used, resulting in low efficiency and consequently low work efficiency, placing a heavy burden on the workers. In addition, after spraying, it is necessary to add cleaning agent to the glue bottle and reinstall it to clean the sprayed substrate and glue gun, which is quite troublesome and further reduces operational efficiency. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a multi-purpose foam glue gun with a cleaning function. This addresses the problem that existing foam glue guns have a limited function, only capable of spraying foam glue alone. If a drying agent needs to be sprayed, a different set of glue bottles must be used, resulting in low efficiency and consequently low work efficiency, placing a heavy burden on workers. Furthermore, after spraying, additional cleaning agent needs to be added to the glue bottle before reinstallation to clean the sprayed substrate and the glue gun, making the operation cumbersome and further contributing to low operational efficiency.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0007] A multi-purpose foam adhesive gun with a cleaning function includes: a glue gun assembly, a first mounting assembly, a second mounting assembly, and a third mounting assembly. The glue gun assembly includes a delivery tube. The first and second mounting assemblies are both disposed at the top of the delivery tube, and the third mounting assembly is disposed at the bottom of the delivery tube. The first and second mounting assemblies each include a glue bottle.

[0008] The first glue bottle of the first installation component contains a foaming agent, the first glue bottle of the second installation component contains a foaming agent or a drying agent, and the third installation component includes a second glue bottle containing a drying agent or a cleaning agent. The first, second, and third installation components also include a first connecting structure, a second connecting structure, and a third connecting structure, respectively. The first glue bottle of the first installation component is connected to the delivery pipe through the first connecting structure, the first glue bottle of the second installation component is connected to the delivery pipe through the second connecting structure, and the second glue bottle is connected to the delivery pipe through the third connecting structure.

[0009] Furthermore, the glue bottle of the second installation component is internally equipped with a foaming agent and a drying agent.

[0010] Furthermore, the glue gun assembly also includes a glue gun handle, a flow switch, a control wrench, a glue gun barrel, and an output head. A connecting bracket is fixedly installed on the top of the glue gun handle, the flow switch is inserted into the interior of the connecting bracket, and the top of the control wrench is movably connected to the connecting bracket.

[0011] Furthermore, the other end of the connecting frame is fixedly connected to the delivery pipe, the glue gun wrench is movably sleeved on the outside of the middle section of the flow switch, one end of the flow switch is movably inserted into the inside of the delivery pipe, one end of the glue gun barrel is connected to the delivery pipe, and the other end of the glue gun barrel is fixedly connected to the output head.

[0012] Furthermore, each of the three connection structures includes a connecting pipe, a valve stem, a snap-fit ​​groove, a threaded seat, a connecting piece, a lever, and a valve ball. One end of the connecting pipe is connected to the delivery pipe, and the other end of the connecting pipe is connected to the snap-fit ​​groove.

[0013] Furthermore, the connecting piece is fixedly installed on the outer wall of the connecting pipe, and the other side of the connecting piece is fixedly connected to the threaded seat. A valve stem is provided inside the connecting pipe. One end of the valve stem is fixedly connected to the valve ball, and a paddle is fixedly sleeved on the other end of the valve stem. Plug base one and plug base two are fixedly installed at the output ends of both the first and second glue bottles.

[0014] Furthermore, the first and second glue bottle bases include a snap-fit ​​connector, a limiting ring, and a threaded head. The threaded head is fixedly installed at the output end of the first and second glue bottles, the snap-fit ​​connector is fixedly installed at the end of the threaded head away from the first and second glue bottles, and the limiting ring is fixedly sleeved on the outer wall of the output end of the first and second glue bottles.

[0015] The beneficial effects of this utility model are:

[0016] By incorporating mounting components and connecting structures, foaming agent can be filled into glue bottle one of mounting component one, while foaming agent or drying agent can be filled separately into glue bottle one of mounting component two. Alternatively, a mixture of foaming agent and drying agent can be filled into glue bottle one of mounting component two, and drying agent or cleaning agent can be filled separately into glue bottle two of mounting component three. Glue bottles one and two can be installed on the outside of the delivery pipe via connecting structures one, two, and three, respectively. Connecting structures one, two, and three can control the use of glue bottles one and two independently. The use of various combinations of glue bottles allows the glue gun to spray foaming agent and drying agent in one integrated manner, eliminating the need for multiple glue bottle changes, improving efficiency and reducing the burden on workers. The cleaning agent ensures that the foaming agent and drying agent in glue bottle one are sprayed more thoroughly. The cleaning agent has multiple uses; it can be used to directly clean the substrate and also to clean the glue gun. Connecting structures one and two must be connected during use.

[0023] It should also be understood that the terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the scope of the invention. As used in this specification and the appended claims, the singular forms “a,” “an,” and “the” are intended to include the plural forms unless the context clearly indicates otherwise.

[0024] It should also be further understood that the term "and / or" as used in this specification and the appended claims refers to any combination of one or more of the associated listed items and all possible combinations, and includes such combinations.

[0025] Please refer to Figure 1-2. A multi-purpose foam glue gun with a cleaning function includes: a glue gun assembly, a first mounting assembly 21, a second mounting assembly 22, and a third mounting assembly 23. The glue gun assembly includes a delivery tube 4. The first mounting assembly 21 and the second mounting assembly 22 are both located at the top of the delivery tube 4, and the third mounting assembly 23 is located at the bottom of the delivery tube 4. The first mounting assembly 21 and the second mounting assembly 22 both include a glue bottle 12.

[0026] The glue bottle 12 of mounting component 1 21 contains a foaming agent. The glue bottle 12 of mounting component 2 22 contains a foaming agent or a drying agent. Mounting component 3 23 includes glue bottle 2 16, which contains a drying agent or a cleaning agent. Mounting components 1 21, 2 22, and 3 23 also include connecting structures 1, 2, and 3, respectively. Glue bottle 12 of mounting component 1 21 is connected to the delivery pipe 4 via connecting structure 1. Glue bottle 12 of mounting component 2 22 is connected to the delivery pipe 4 via connecting structure 2. Glue bottle 2 16 is connected to the delivery pipe 4 via connecting structure 3. Glue bottle 12 of mounting component 2 22 contains a combination of a foaming agent and a drying agent. Furthermore, for two-component adhesives, especially two-component foamed adhesives, the glue gun barrel 5 can be replaced with a mixing tube, or a static mixing tube can be used. A can then be added to glue bottle 12 of mounting component 21. Type B raw materials are added to glue bottle 12 in installation component 22. Alternatively, a drying agent can be added to either type A or type B raw materials as needed to allow the adhesive to dry quickly. When in use, type A and type B raw materials can be transported to the mixing tube for mixing to form a ready-to-use two-component foam adhesive for extrusion. At the same time, a cleaning agent is added to glue bottle 16 in installation component 33 to clean the remaining adhesive material in the glue gun, preventing the remaining material from affecting secondary use.

[0027] Specifically, by providing installation components and connecting structures, during use, foaming agent can be filled inside the glue bottle 12 of installation component one 21, and foaming agent or drying agent can be filled separately inside the glue bottle 12 of installation component two 22. Alternatively, a mixture of foaming agent and drying agent can be filled inside the glue bottle 12 of installation component two 22, and drying agent or cleaning agent can be filled separately inside the glue bottle 16 of installation component three 23. Glue bottle one 12 and glue bottle two 16 can be installed outside the delivery pipe 4 through connecting structures one, two, and three, respectively. Connecting structures one, two, and three can respectively connect glue bottle one 12 and glue bottle two 16. These devices are individually controlled and installed using various combinations of glue bottles, allowing the glue gun to spray expanding foam and drying agent in one unit. This eliminates the need for frequent bottle changes, improving efficiency and reducing worker workload. A cleaning agent is also included to ensure thorough cleaning of both the expanding foam and drying agent in glue bottle 12. This cleaning agent has multiple uses, including cleaning the substrate and the glue gun itself. During use, both connecting structures 1 and 2, as well as glue bottle 12, are tilted to facilitate smooth delivery of the expanding foam and prevent it from adhering to the sides, further enhancing efficiency.

[0028] In this embodiment, the glue gun assembly also includes a glue gun handle 1, a flow switch 2, a control wrench 3, a glue gun barrel 5, and an output head 6. A connecting frame is fixedly installed on the top of the glue gun handle 1. The flow switch 2 is inserted into the interior of the connecting frame. The top of the control wrench 3 is movably connected to the connecting frame, and the other end of the connecting frame is fixedly connected to the delivery pipe 4. The glue gun wrench is movably sleeved on the outside of the middle section of the flow switch 2. One end of the flow switch 2 is movably inserted into the interior of the delivery pipe 4. One end of the glue gun barrel 5 is connected to the delivery pipe 4, and the other end of the glue gun barrel 5 is fixedly connected to the output head 6.

[0029] Specifically, in use, hold the glue gun handle 1 and adjust the position of the glue gun body as needed. Then, by pulling the control lever 3 with the index and middle fingers, the flow switch 2 can be moved, thereby pushing the polyurethane sealant to move and thus realizing the output of the sealant. In use, the polyurethane sealant flows from the glue bottle to the inside of the connecting tube 7, and then is delivered to the inside of the delivery tube 4, thereby opening the flow switch 2. By rotating the flow switch 2, the total stroke of the flow switch 2 can be changed, thereby controlling the flow rate of the sealant. The sealant strip is then output through the glue gun barrel 5 and the output head 6. The technology used is existing technology, such as glue guns and other equipment.

[0030] Connection structures one, two, and three all include a connecting pipe 7, a valve stem 8, a snap-fit ​​groove 9, a threaded seat 10, a connecting piece 18, a lever 19, and a valve ball 20. One end of the connecting pipe 7 is connected to the delivery pipe 4, and the other end of the connecting pipe 7 is connected to the snap-fit ​​groove 9. The connecting piece 18 is fixedly installed on the outer wall of the connecting pipe 7, and the other side of the connecting piece 18 is fixedly connected to the threaded seat 10. The valve stem 8 is provided inside the connecting pipe 7. One end of the valve stem 8 is fixedly connected to the valve ball 20, and the other end of the valve stem 8 is fixedly sleeved with a lever. The output ends of glue bottle one 12 and glue bottle two 16 are both fixedly installed with glue bottle base one 15 and glue bottle base two 17. Glue bottle base one 15 and glue bottle base two 17 include a snap-fit ​​connector 11, a limiting ring 13, and a threaded head 14. The threaded head 14 is fixedly installed at the output end of glue bottle one 12 and glue bottle two 16, and the snap-fit ​​connector 11 is fixedly installed at the threaded head 14. At the end furthest from Glue Bottle 12 and Glue Bottle 2, the limiting ring 13 is fixedly sleeved on the outer wall of the output end of Glue Bottle 12 and Glue Bottle 2.

[0031] Specifically, by setting up connection structure one and connection structure two, during use, glue bottle base one 15 and glue bottle base two 17 are threadedly installed with the connection structure, and then the lever 19 is rotated, which causes the valve stem 8 to drive the valve ball 20 to rotate, thereby controlling the discharge of polyurethane sealant individually. Furthermore, by setting an independent ball valve switch inside the delivery pipe 4, after each application of sealant, the ball switch can be operated to close the connection between the glue bottle outlet and the delivery pipe 4, cleaning up the remaining sealant in the glue gun barrel 5 and the delivery pipe 4. The glue gun barrel 5 and the delivery pipe 4 are then clean, with no residual sealant, saving sealant, time, and construction costs.

[0032] In summary, compared with existing technologies, this glue gun has at least the following beneficial effects: By incorporating mounting components and connecting structures, during use, foaming agent can be filled inside glue bottle 12 of mounting component 1 21; foaming agent or drying agent can be filled separately inside glue bottle 12 of mounting component 2 22; a mixture of foaming agent and drying agent can be filled inside glue bottle 12 of mounting component 2 22; and drying agent or cleaning agent can be filled separately inside glue bottle 2 16 of mounting component 3 23. Glue bottle 12 and glue bottle 2 16 can be installed outside the delivery pipe 4 via connecting structures 1, 2, and 3 respectively. Connecting structures 1, 2, and 3 can respectively handle glue bottle 12 and glue bottle 2 16. Each component is controlled independently, and multiple combinations of glue bottles are used for installation, allowing the glue gun to spray foam and drying agent in one unit. This eliminates the need for frequent bottle changes, improving efficiency and reducing the burden on workers. A cleaning agent is also included to ensure thorough cleaning of the foam and drying agent in glue bottle 12. This cleaning agent has multiple uses, including cleaning the substrate and the glue gun itself. When using this cleaning agent, connection structure one and connection structure two must be connected.

[0033] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in this utility model, and these modifications or substitutions should all be covered within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
