Description

Technical Field

[0001] This utility model relates to the field of hot melt adhesive machine technology, specifically to a pneumatic pump hot melt adhesive machine. Background Technology

[0002] Hot melt adhesive machines are widely used in numerous industries, such as printing, packaging, automotive, clothing and footwear, electronics, furniture, and home appliances, in product assembly. However, existing hot melt adhesive machines have several problems. Some machines have poorly designed melting cylinders, often with a flat bottom, meaning the adhesive is only heated from the bottom, resulting in slow melting. Furthermore, to ensure the adhesive can be distributed to different external pipes, a distributor block needs to be connected to the pump outlet. However, once the adhesive flows into the distributor block, the heat dissipates easily, causing it to cool and solidify, leading to blockages and difficult cleaning. Therefore, a pneumatic pump hot melt adhesive machine is provided to solve these problems. Utility Model Content

[0003] To address the problems mentioned in the background art, the technical solution adopted by this utility model is: a pneumatic pump hot melt glue machine, comprising: a machine body, a glue melting cylinder fixedly installed inside the machine body, a heating tube horizontally embedded inside the bottom end of the glue melting cylinder, a flow divider block fixedly connected to one side of the bottom end of the glue melting cylinder, one end of the heating tube being tightly attached to the top of the flow divider block, a safety valve connected to one side of the top of the flow divider block, and the safety valve extending into the inside of the glue melting cylinder, a heat-conducting strip plate provided on the bottom side inside the glue melting cylinder, and a pneumatic pump fixedly installed on one side of the machine body located on the glue melting cylinder.

[0004] As a preferred technical solution of this utility model, the pneumatic pump includes a telescopic cylinder, a pump body fixedly connected to the bottom end of the telescopic cylinder, a material extraction piston groove longitudinally opened inside the pump body, a hollow piston slidably connected inside the material extraction piston groove, a first sealing steel ball longitudinally movably connected inside the hollow piston, and a glue outlet joint provided on one side of the bottom end of the pump body. A second sealing steel ball is movably connected to one side of the lower end inside the material extraction piston groove.

[0005] As a preferred technical solution of this utility model, the material extraction piston groove is provided with a limit rod on the side above the second sealing steel ball, the hollow piston is provided with a through hole on the side above the first sealing steel ball, the material extraction piston groove is connected to the glue outlet connector on the side above the through hole, and the output end of the telescopic cylinder is connected to the hollow piston.

[0006] As a preferred technical solution of this utility model, a reversing solenoid valve is provided at the top of the air pump. The reversing solenoid valve is connected to the telescopic cylinder. A pressure gauge is provided on one side of the upper end of the reversing solenoid valve. An air pressure adjustment knob is provided at the top of the reversing solenoid valve.

[0007] In a preferred embodiment of this utility model, a horizontally formed diversion channel is provided inside the diversion block. The top of the diversion block is aligned with the dispensing connector of the pump body. The dispensing connector is connected to the diversion channel, which is connected to the safety valve. As a preferred technical solution of this utility model, the machine body is provided with an electrical control for the glue machine located on one side of the glue melting cylinder. The glue melting cylinder has a glue inlet at the top. The top of the machine body is connected to the melting cylinder cover via a shaft at the glue inlet. A liquid level probe is fixedly installed on the upper end of the glue melting cylinder.

[0008] This utility model has the following advantages: It heats the glue melting cylinder, heat-conducting strips, and distributor block simultaneously by using multiple sets of heating tubes at the bottom of the glue melting cylinder. When the glue block is initially melted, it will fully contact the surface of the arranged heat-conducting strips, effectively improving the heating and melting efficiency. The heating tube ends heat the distributor block, so that after the air pump pumps the glue liquid in the glue melting cylinder to the distributor block, it will not cool down and solidify, which would cause cleaning trouble. In addition, the safety valve on the distributor block can effectively ensure that when the external pipeline connected to the distributor block is blocked, the pressure can be released and discharged into the glue melting cylinder.

[0013] The present invention will be further described below with reference to the accompanying drawings.

[0014] Please refer to the following: Figures 1-5 The present invention relates to a pneumatic pump hot melt glue machine, comprising: a machine body 1, a glue melting cylinder 2 fixedly installed inside the machine body 1, a heating tube 4 horizontally embedded inside the bottom end of the glue melting cylinder 2, a flow divider block 15 fixedly connected to one side of the bottom end of the glue melting cylinder 2, one end of the heating tube 4 being tightly attached to the top end of the flow divider block 15, a safety valve 16 connected to one side of the top end of the flow divider block 15, and the safety valve 16 extending into the interior of the glue melting cylinder 2, a heat-conducting strip plate 5 being provided on the bottom side inside the glue melting cylinder 2, and a pneumatic pump fixedly installed on one side of the glue melting cylinder 2 in the machine body 1.

[0015] The pneumatic pump includes a telescopic cylinder 6, a pump body 7 fixedly connected to the bottom of the telescopic cylinder 6, a longitudinally formed material extraction piston groove 12 inside the pump body 7, a hollow piston 8 slidably connected inside the material extraction piston groove 12, a first sealing steel ball 9 longitudinally movably connected inside the hollow piston 8, and a glue dispensing connector 14 set on one side of the bottom of the pump body 7. A second sealing steel ball 11 is movably connected to one side of the lower end inside the material extraction piston groove 12. A limit rod 13 is set on one side of the material extraction piston groove 12 above the second sealing steel ball 11. A through hole 10 is formed on one side of the hollow piston 8 above the first sealing steel ball 9. The side of the material extraction piston groove 12 above the through hole 10 communicates with the glue dispensing connector 14. The output end of the telescopic cylinder 6 is connected to the hollow piston 8. When the output end of the telescopic cylinder 6 drives the hollow piston 8 to rise, the adhesive liquid in the glue melting cylinder 2 can be drawn through the bottom of the material extraction piston groove 12. Then, the telescopic cylinder 6 drives the hollow piston 8 to descend. At this time, the second sealing steel ball 11 at the bottom of the material extraction piston groove 12 is sealed, so that the extracted adhesive liquid is pressed down and pushes the first sealing steel ball 9 in the hollow piston 8 upward. Then, it flows into the glue outlet connector 14 through the through hole 10, and then into the diverter block 15 through the glue outlet connector 14. Multiple external glue supply pipelines can be connected through the diverter block 15.

[0016] The air pump is equipped with a reversing solenoid valve 18 at its top, which is connected to the telescopic cylinder 6. A pressure gauge 20 is installed on one side of the upper end of the reversing solenoid valve 18, and a pressure adjustment knob 19 is installed at its top. A diversion block 15 has a horizontal diversion channel inside, and its top end matches the glue outlet connector 14 of the pump body 7. The glue outlet connector 14 is connected to the diversion channel, which is connected to the safety valve 16. The machine body 1 is equipped with an electrical control system 21 on one side of the glue melting cylinder 2. The glue melting cylinder 2 has a glue inlet 3 at its top, and a melting cylinder cover 22 is connected to the top of the machine body 1 at the glue inlet 3 via a shaft. A liquid level probe 17 is fixedly installed on the upper end of the glue melting cylinder 2. The liquid level probe 17 is a W80 model, which monitors the liquid level of the melted glue inside the glue melting cylinder 2 in real time and transmits the monitoring data to the glue melting cylinder electrical control system 21 in real time. The pressure gauge 20 allows for a direct view of the adjusted air pressure. The electrical control system 21 of the glue-making machine is electrically connected to the reversing solenoid valve 18, the heating tube 4, and the air pump.

[0017] Specifically, when using this invention, the melting cylinder cover 22 is opened, and the glue block to be melted is placed into the glue machine melting cylinder 2. The heating parameters are adjusted through the operation panel on the glue machine electrical control 21, which causes the multiple sets of heating tubes 4 at the bottom of the glue machine melting cylinder 2 to heat up. This, in turn, heats up the glue block and the heat-conducting strips 5 distributed inside the glue machine melting cylinder 2. When the glue block melts, it will fully contact the surface of the arranged heat-conducting strips 5, thereby improving the heating and melting efficiency. Furthermore, the heating tubes 4 at the bottom of the glue machine melting cylinder 2 can heat the diversion block 15, so that the glue liquid in the glue machine melting cylinder 2 will not cool down and solidify after the air pressure pump pumps it into the diversion block 15.

[0018] The above are merely preferred embodiments of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.

[0019] All other parts of this utility model that are not described in detail belong to the prior art, and therefore will not be described in detail here.

[0020] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
