By pulling the trigger on the glue spray gun 37, the molten hot melt glue can be controlled to be sprayed from the glue spray gun 37. Wherein:

[0027] The hot melt glue machine 1 is equipped with a crushing mechanism for crushing solid hot melt glue. The crushing mechanism includes a crushing cylinder 7, two upper support rods 8, multiple fixed crushing teeth 9, a bearing seat 10, two lower support rods 11, a vertical shaft 12, multiple rotating crushing teeth 13, a bevel gear 14, a drive shaft 16, a bevel gear 17, a machine base 18, and a motor 19. The crushing cylinder 7 is located inside the melt glue cylinder 2 and directly below the feed pipe 6. The top and bottom of the crushing cylinder 7 are open. The two upper support rods 8 are fixedly installed on the outer walls of both sides of the crushing cylinder 7. The ends of the two upper support rods 8 that are far apart from each other are respectively connected to the two sides of the melt glue cylinder 2. The inner wall is fixedly connected, and multiple fixed crushing teeth 9 are fixedly installed inside the crushing cylinder 7 and arranged in a ring array. The bearing seat 10 is set inside the molten cylinder 2 and located directly below the crushing cylinder 7. Two lower support rods 11 are respectively fixedly installed on the outer walls of the two sides of the bearing seat 10, and the ends of the two lower support rods 11 that are far apart from each other are fixedly connected to the inner walls of the two sides of the crushing cylinder 7. The vertical shaft 12 is rotatably installed on the bearing seat 10, and the top end of the vertical shaft 12 extends into the crushing cylinder 7. Multiple rotating crushing teeth 13 are fixedly installed on the vertical shaft 12 and arranged in a ring array, and the multiple rotating crushing teeth 13 are all located inside the crushing cylinder 7. The crushing teeth 13 and multiple fixed crushing teeth 9 are alternately distributed. A bevel gear 14 is fixedly mounted on the vertical shaft 12 and located below the support seat 10. A horizontal hole 1 is provided on the right side wall of the melt glue cylinder 2. A groove 15 is provided on the right side wall of the hot melt glue machine 1. A second horizontal hole communicating with the first horizontal hole is provided on the left inner wall of the groove 15. The drive shaft 16 is rotatably installed in the first horizontal hole. A second bevel gear 17 is fixedly installed on the left end of the drive shaft 16, meshing with the first bevel gear 14. The right end of the drive shaft 16 passes through the second horizontal hole and extends into the groove 15. The machine base 18 is fixedly installed on the right outer wall of the hot melt glue machine 1. The motor 19 is fixedly mounted on the second horizontal hole. The motor 19 is fixedly mounted on the base 18. The output shaft of the motor 19 extends into the groove 15 and is fixedly connected to the right end of the drive shaft 16. The motor 19 is used to control the rotation of the drive shaft 16 and the bevel gear 17. By utilizing the meshing transmission between the bevel gear 17 and the bevel gear 14, the vertical shaft 12 can be controlled to rotate, thereby causing the rotating crushing teeth 13 to rotate with the vertical shaft 12. Under the combined action of multiple rotating crushing teeth 13 and multiple fixed crushing teeth 9, the solid hot melt adhesive falling from the feed pipe 6 can be fully and effectively crushed, preventing large pieces of solid hot melt adhesive from entering the melt cylinder 2 and affecting the subsequent melt quality and melt efficiency.

[0028] In this embodiment, the hot melt glue machine 1 is also equipped with a material control mechanism for controlling the intermittent entry of solid hot melt glue into the melt cylinder 2. The material control mechanism includes a shaft seat 21, a second vertical shaft 22, a baffle plate 23, and a transmission assembly. The hot melt glue machine 1 has an installation groove 20 located above the melt cylinder 2. The shaft seat 21 is fixedly installed on the top inner wall of the installation groove 20. The second vertical shaft 22 is rotatably installed on the bottom of the shaft seat 21, and the bottom end of the second vertical shaft 22 extends into the melt cylinder 2. The baffle plate 23 is fixedly installed on the bottom end of the second vertical shaft 22 and is located between the feed pipe 6 and the crushing cylinder 7. The top of the baffle plate 23 has a discharge hole 24 located directly below the feed pipe 6. The diameter of the feed pipe 6 is smaller than the diameter of the discharge hole 24, and the diameter of the discharge hole 24 is smaller than the diameter of the crushing cylinder 7. The bottom of the feed pipe 6 is in sliding sealing contact with the top of the baffle plate 23, and the top of the crushing cylinder 7 is in sliding sealing contact with the bottom of the baffle plate 23. The transmission assembly is used to control the rotation of the vertical shaft 22. The vertical shaft 22 drives the baffle plate 23 to rotate, which allows the discharge hole 24 to intermittently connect with the feed pipe 6, so that the solid hot melt adhesive contained in the cylinder 4 can be intermittently discharged. To avoid excessive solid hot melt adhesive entering the crushing cylinder 7 at once, which would increase the crushing burden and improve the crushing effect, the transmission assembly includes a drive shaft 25, a main pulley 26, a secondary pulley 27, a belt 28, a bevel gear 39, and a bevel gear 40. A common transverse hole 3 is provided between the mounting groove 20 and the recess 15. The drive shaft 25 is rotatably mounted within the transverse hole 3, with its right end extending into the recess 15. The main pulley 26 is fixedly fitted onto the right end of the drive shaft 16, and the secondary pulley 27 is fixedly fitted onto the drive shaft 25. At the right end, belt 28 is wound around main pulley 26 and auxiliary pulley 27. Bevel gear 3 29 is fixedly installed on the left end of drive shaft 25. Bevel gear 4 30 is fixedly fitted on vertical shaft 22 and located in mounting groove 20. Bevel gear 3 29 meshes with bevel gear 4 30. By utilizing the transmission action of main pulley 26, auxiliary pulley 27 and belt 28, drive shaft 16 and drive shaft 25 can be controlled to rotate simultaneously. By utilizing the mutual meshing transmission of bevel gear 3 29 and bevel gear 4 30, the power of drive shaft 25 is transmitted to vertical shaft 22 to drive baffle 23 to rotate.

[0029] In this embodiment, a sealed bearing 31 is fixedly mounted on the drive shaft 16. The outer ring of the sealed bearing 31 is fixedly connected to the inner wall of the transverse hole, which not only ensures the smooth and stable operation of the drive shaft 16 during rotation, but also prevents the hot melt adhesive in the melt cylinder 2 from leaking from the transverse hole, thus maintaining a good working environment inside the device.

[0030] In this embodiment, the top of the support seat 10 is an arc-shaped surface and the top of the lower support rod 11 is an inclined surface, which can prevent the pulverized solid hot melt adhesive from accumulating on the top of the support seat 10 and the top of the lower support rod 11. A stirring rod 33 located below the drive shaft 16 is fixedly installed on the vertical shaft 12. The stirring rod 33 can stir and disperse the pulverized hot melt adhesive, which can further improve the efficiency of heating and melting the pulverized solid hot melt adhesive.

[0031] In this embodiment, a sealed bearing 32 is fixedly mounted on the drive shaft 25. The outer ring of the sealed bearing 32 is fixedly connected to the inner wall of the transverse hole 3, which ensures the stability of the drive shaft 25 during rotation and the sealing of the device.

[0032] In this embodiment, the diameter of the main pulley 26 is smaller than that of the auxiliary pulley 27. The bevel gear 3 29 and the bevel gear 2 17 are of the same model, and the bevel gear 4 30 and the bevel gear 1 14 are of the same model. This ensures that the rotational speed of the drive shaft 16 is greater than that of the transmission shaft 25, which in turn makes the rotational speed of the vertical shaft 1 12 greater than that of the vertical shaft 2 22. This better adapts to the different operating requirements of the crushing mechanism and the material control mechanism, ensuring the coordination and effectiveness of their collaborative work, and further improving the overall control level of the entire glue feeding device for solid hot melt glue feeding, crushing and other processes.

[0033] In this embodiment, it should be noted that a controller is fixedly installed on the outer wall of the hot melt glue machine. The controller is equipped with a display screen and multiple control buttons. The annular electric heating plate 3, the motor 19, the electromagnetic glue discharge valve 35 and the controller are electrically connected. The display screen is used to display the heating temperature value of the annular electric heating plate 3, and the multiple control buttons are used to control the power supply and operation of the annular electric heating plate 3, the motor 19 and the electromagnetic glue discharge valve 35 respectively.

[0034] With the above structure, the working principle of the glue feeding device of the glue spraying robot provided in this application is as follows:

[0035] Pour solid hot melt adhesive into the material cylinder 4, then tighten the sealing cap 5 onto the top of the material cylinder 4. Start the motor 19. The motor 19 drives the drive shaft 16, bevel gear 17, and main pulley 26 to rotate. The meshing transmission between bevel gear 17 and bevel gear 14 controls the vertical shaft 12 to drive multiple rotating crushing teeth 13 to rotate. The transmission action of the main pulley 26, auxiliary pulley 27, and belt 28 controls the simultaneous rotation of the drive shaft 16 and transmission shaft 25. The meshing transmission between bevel gear 39 and bevel gear 4 30 controls the vertical shaft 22 to drive the stop. The material tray 23 rotates, and the rotation speed of the first vertical shaft 12 is greater than that of the second vertical shaft 22. During the rotation of the material tray 23, the discharge hole 24 can be intermittently connected to the feed pipe 6, so that the solid hot melt adhesive contained in the material cylinder 4 can enter the crushing cylinder 7 intermittently through the feed pipe 6 and the discharge hole 24. By using the rotation of multiple rotating crushing teeth 13 and the use of multiple fixed crushing teeth 9, the solid hot melt adhesive entering the crushing cylinder 7 can be fully and effectively crushed. The crushed solid hot melt adhesive falls onto the bottom inner wall of the melt cylinder 2.

[0036] During the process of controlling the feeding and crushing of solid hot melt adhesive, turning on the annular electric heating plate 3 can heat the internal space of the melting cylinder 2, which can make the crushed solid hot melt adhesive melt faster in the melting cylinder 2, thus improving the melting efficiency. Furthermore, by using the vertical shaft 12 to drive the stirring rod 33 to rotate, the crushed solid hot melt adhesive can be stirred and dispersed, which can further improve the efficiency of heating and melting the crushed solid hot melt adhesive.

[0037] After the solid hot melt adhesive has been heated and melted, the motor 19 is stopped, the electromagnetic glue discharge valve 35 is opened, and the worker holds the glue spray gun 37 and pulls the trigger on the glue spray gun 37 to control the hot melt adhesive in the molten state to be sprayed out from the glue spray gun 37.
