Description

Technical Field

[0001] This application relates to the field of hot melt adhesive spraying technology, and in particular to a manual hot melt adhesive spray gun. Background Technology

[0002] Hot melt adhesive is a type of malleable adhesive whose physical state changes with temperature within a certain temperature range, while its chemical properties remain unchanged. It is non-toxic, odorless, and an environmentally friendly chemical product. It is highly favored due to its solid nature, ease of packaging, transportation, and storage; solvent-free, pollution-free, and non-toxic properties; simple production process; high added value; and advantages such as strong and fast bonding.

[0003] In existing technology, when applying hot melt adhesive to relatively large workpieces to facilitate bonding with other parts, a spraying station is often required. The spraying station's frame is fixedly mounted beside the hot melt adhesive machine. A clamping mechanism for securing the workpiece is installed on the spraying station. The hot melt adhesive machine is connected to a handheld spray gun via a hot melt adhesive delivery pipe. The handheld spray gun has a fixed grip for the operator, and a control solenoid valve is mounted on the grip. A hot melt adhesive delivery pump is installed on the hot melt adhesive delivery pipe, and the signal input of the hot melt adhesive delivery pump is connected to the signal output of the control solenoid valve. During the actual spraying process, the operator can hold the handheld spray gun and press the control solenoid valve to spray hot melt adhesive onto the workpiece.

[0004] However, due to the long length and weight of the hot melt adhesive delivery pipe, operators need to hold the hot melt adhesive spray gun with one hand and the hot melt adhesive delivery pipe with the other hand when using the hot melt adhesive spray gun to spray hot melt adhesive on the surface of the workpiece. This is time-consuming and laborious, and there is room for improvement. Utility Model Content

[0005] To make the operation of applying adhesive using a spray gun more labor-saving and convenient for operators, this application provides a manual hot melt adhesive spray gun.

[0006] The hot melt adhesive manual spray gun provided in this application adopts the following technical solution:

[0007] A manual hot melt adhesive spray gun includes a frame and a gun body. A slide rail is mounted on the frame and is mounted above a clamping mechanism on a spraying workbench. A fixed base is fixedly mounted on the end of the slide rail near the hot melt adhesive machine. A sliding base is slidably mounted on the slide rail. Two positioning ropes are fixedly mounted on the adhesive delivery pipe. The ends of the two positioning ropes away from the adhesive delivery pipe are fixedly connected to the fixed base and the sliding base, respectively.

[0008] Hand grips are fixedly installed on both sides of the glue gun body. Two control solenoid valves are also fixedly installed on the glue gun body, and the two control solenoid valves are located on the sides of the two hand grips respectively.

[0009] By adopting the above technical solution, during the actual glue application process, the operator can hold the handle with both hands and start the glue gun by controlling the solenoid valve on the glue gun body to spray hot melt glue to complete the glue application process on the workpiece. During the glue application process, since the glue delivery pipe is fixed to the fixed seat and the sliding seat by the positioning rope, and the sliding seat can slide on the slide rail, as the operator moves the position of the spray gun, the sliding seat that fixes the glue delivery pipe slides on the slide rail, which can form support for the glue delivery pipe, reduce the load on the operator during the glue application process, and make the operation of using the spray gun for glue application more labor-saving and convenient.

[0010] Preferably, anti-detachment parts are fixedly installed on both sides of the slide rail, and the sliding seat includes two oppositely arranged side plates. An extension part is integrally formed on the opposite side wall of the two side plates, and the two extension parts are respectively located at the bottom of the two anti-detachment parts.

[0011] Both the sliding seat and the fixed seat are respectively fixedly installed with connecting rings for fixing the positioning rope;

[0012] Several first rollers are rotatably mounted on the opposite side walls of the two side plates, and the wheel surfaces of the several first rollers abut against the two sides of the slide rail.

[0013] By adopting the above technical solution, the positioning rope for fixing the colloid delivery pipeline can be fixed to the sliding seat and the positioning seat through the connecting ring. The first roller is close to both sides of the slide rail. As the sliding seat slides along the slide rail, the first roller rolls on both sides of the slide rail, which can effectively improve the smoothness of the sliding seat. The extension part and the anti-detachment part work together to restrict the position of the sliding seat and reduce the occurrence of the sliding seat tilting or falling off the slide rail.

[0014] Preferably, a plurality of second rollers are rotatably mounted inside the sliding seat, and the wheel surfaces of the plurality of second rollers abut against the top of the slide rail.

[0015] By adopting the above technical solution, the second roller rolls on the slide rail while the sliding seat slides along the slide rail, which can further improve the smoothness of the sliding seat sliding on the slide rail.

[0016] Preferably, two lead screws are rotatably mounted on the frame, each lead screw is mounted with a mounting seat, and mounting plates are fixedly mounted on both ends of the two slide rails, with the two mounting plates fixedly mounted on the two mounting seats respectively.

[0017] Two servo motors are fixedly mounted on the frame. The two servo motors are respectively connected to the two lead screws through couplings. A control panel is fixedly mounted on the frame. The signal output terminal of the control panel is connected to the signal input terminal of the two servo motors.

[0018] By adopting the above technical solution, when installing or adjusting the position of the colloid delivery pipeline, the operator can input commands through the control panel to control two servo motors to drive two lead screws to rotate, causing the mounting base and slide rail to descend; after the operation is completed, the operator can input commands through the control panel to control the two servo motors to drive the slide rail to reset and rise.

[0019] Preferably, a magnetic adsorption base is fixedly installed on the frame, and an adsorption block is fixedly installed on the glue gun body.

[0020] By adopting the above technical solution, the magnetic adsorption base makes it easy for operators to fix the glue gun on the frame after use, thus improving the convenience of storing the glue gun.

[0021] Preferably, a storage box is detachably installed on the frame, and the storage box is located below the magnetic adsorption base.

[0022] By adopting the above technical solution, the collection box located below the magnetic adsorption base can collect the residual or spilled glue from the glue gun, preventing the glue from falling onto the ground and becoming difficult to clean.

[0023] In summary, the hot melt adhesive manual spray gun of this application has at least one of the following beneficial technical effects:

[0024] 1. During the actual glue application process, the operator can hold the handle with both hands and start the glue gun by controlling the solenoid valve on the glue gun body to spray hot melt glue to complete the glue application process on the workpiece. During the glue application process, since the glue delivery pipe is fixed to the fixed seat and the sliding seat by the positioning rope, and the sliding seat can slide on the slide rail, as the operator moves the position of the spray gun, the sliding seat that fixes the glue delivery pipe slides on the slide rail, which can form support for the glue delivery pipe, reduce the load on the operator during the glue application process, and make the operation of the spray gun for glue application more labor-saving and convenient.

[0025] 2. When installing or adjusting the position of the colloid delivery pipeline, the operator can input commands through the control panel to control two servo motors to drive two lead screws to rotate, causing the mounting base and slide rail to descend; after the operation is completed, the operator can input commands through the control panel to control the two servo motors to drive the slide rail to reset and rise.

[0029] The following is in conjunction with the appendix Figure 1-2 This application will be described in further detail.

[0030] Example

[0031] This application discloses a manual hot melt adhesive spray gun. (Refer to...) Figure 1 and Figure 2 It mainly includes a frame 1 and a glue gun body 2. A slide rail 3 is installed on the frame 1 and can be raised and lowered. The slide rail 3 is mounted above the clamping mechanism on the glue spraying workbench. A fixed seat 5 is fixedly installed at the end of the slide rail 3 near the hot melt glue machine 4. A sliding seat 6 is slidably installed on the slide rail 3. Two positioning ropes 71 are fixedly installed on the glue delivery pipe 7. The ends of the two positioning ropes 71 away from the glue delivery pipe 7 are fixedly connected to the fixed seat 5 and the sliding seat 6 respectively. Hand handles 21 are fixedly installed on both sides of the glue gun body 2. Two control solenoid valves 22 are also fixedly installed on the glue gun body 2, and the two control solenoid valves 22 are located on the sides of the two hand handles 21 respectively.

[0032] During the actual glue application process, the operator can hold the handle 21 with both hands and start the glue gun by using the control solenoid valve 22 on the glue gun body 2 to spray hot melt glue to complete the glue application process on the workpiece. During the glue application process, since the glue delivery pipe 7 is fixed to the fixed seat 5 and the sliding seat 6 by the positioning rope 71, and the sliding seat 6 can slide on the slide rail 3, as the operator moves the position of the spray gun, the sliding seat 6 that fixes the glue delivery pipe 7 slides on the slide rail 3, which can form support for the glue delivery pipe 7, reduce the load on the operator during the glue application process, and make the operation of the spray gun for glue application more labor-saving and convenient.

[0033] Reference Figure 1 and Figure 2 The slide rail 3 has anti-detachment parts 31 fixedly installed on both sides. The sliding seat 6 includes two oppositely arranged side plates 61. The two side plates 61 have extension parts 62 that extend inward and are integrally formed on the opposite side walls. The two extension parts 62 are located at the bottom of the two anti-detachment parts 31. The sliding seat 6 and the fixed seat 5 are respectively fixedly installed with connecting rings 63 for fixing the positioning rope 71. A plurality of first rollers 64 are rotatably installed on the opposite side walls of the two side plates 61. The wheel surfaces of the plurality of first rollers 64 abut against the two sides of the slide rail 3.

[0034] The positioning rope 71 for fixing the colloid delivery pipe 7 can be fixed to the sliding seat 6 and the positioning seat by the connecting ring 63. The first roller 64 is close to both sides of the slide rail 3. As the sliding seat 6 slides along the slide rail 3, the first roller 64 rolls on both sides of the slide rail 3, which can effectively improve the smoothness of the sliding seat 6. The extension part 62 and the anti-detachment part 31 work together to restrict the position of the sliding seat 6 and reduce the occurrence of the sliding seat 6 tilting or falling off the slide rail 3.

[0035] Reference Figure 2 A number of second rollers 65 are rotatably mounted inside the sliding seat 6, and the wheel surfaces of the second rollers 65 abut against the top of the slide rail 3.

[0036] As the sliding seat 6 slides along the slide rail 3, the second roller 65 rolls on the slide rail 3, which can further improve the smoothness of the sliding seat 6 sliding on the slide rail 3.

[0037] Reference Figure 1 Two lead screws 11 are rotatably mounted on the frame 1, and mounting seats 12 are respectively mounted on the two lead screws 11. Mounting plates 33 are fixedly mounted on both ends of the two slide rails 3, and the two mounting plates 33 are respectively fixedly mounted on the two mounting seats 12. Two servo motors 13 are fixedly mounted on the frame 1, and the two servo motors 13 are respectively connected to the two lead screws 11 through couplings. A control panel 14 is fixedly mounted on the frame 1, and the signal output terminal of the control panel 14 is connected to the signal input terminal of the two servo motors 13.

[0038] When installing or adjusting the position of the colloid delivery pipe 7, the operator can input commands through the control panel 14 to control the two servo motors 13 to drive the two lead screws 11 to rotate, so that the mounting base 12 and the slide rail 3 descend. After the operation is completed, the operator can input commands through the control panel 14 to control the two servo motors 13 to drive the slide rail 3 to reset and rise.

[0039] Reference Figure 1A magnetic adsorption base 15 is fixedly installed on the frame 1, and an adsorption block 23 is fixedly installed on the glue gun body 2. The magnetic adsorption base 15 makes it easy for operators to fix the glue gun on the frame 1 after use, improving the convenience of storing the glue gun.

[0040] Reference Figure 1 A collection box 16 is detachably mounted on the frame 1 via screws, and the collection box 16 is located below the magnetic adsorption base 15. By using the collection box 16 located below the magnetic adsorption base 15, residual or spilled glue from the glue gun can be collected, preventing residual or spilled glue from falling onto the ground and becoming difficult to clean.

[0041] The implementation principle of a manual hot melt adhesive spray gun according to an embodiment of this application is as follows: During the actual adhesive application process, the operator can hold the handle 21 with both hands and start the gun by controlling the solenoid valve 22 on the gun body 2 to spray hot melt adhesive to complete the adhesive application process on the workpiece. During the adhesive application process, since the adhesive delivery pipe 7 is fixed to the fixed seat 5 and the sliding seat 6 by the positioning rope 71, and the sliding seat 6 can slide on the slide rail 3, when the operator moves the position of the spray gun, the sliding seat 6 that fixes the adhesive delivery pipe 7 slides on the slide rail 3, which can form support for the adhesive delivery pipe 7, reduce the load on the operator during the adhesive application process, and make the operation of the spray gun more labor-saving and convenient.

[0042] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
