Description

Technical Field

[0001] This utility model belongs to the field of hot melt adhesive dispensing, specifically, it relates to a hot melt adhesive dispensing device. Background Technology

[0002] Currently, commonly used hot melt adhesive dispensing mechanisms employ a vertically mounted hot melt adhesive tube inside a heating tank. Since the adhesive changes from a solid to a fluid state upon heating, this type of hot melt adhesive typically uses a cold-fill and cold-removal method: cold filling involves loading the hot melt adhesive into the heating tank while it is still cold and then heating it. It generally takes about 10 minutes for the adhesive inside the tank to reach a usable state after heating, ensuring uniform heating. When removal is needed, the adhesive is cooled before being removed from the heating tank. This cooling process, which requires simultaneous cooling of the heating tank, typically takes about 20 minutes to reach a removable state; otherwise, adhesive leakage will occur. This cold-fill and cold-removal process necessitates a production stoppage of approximately 30 minutes, significantly wasting production efficiency.

The moving adjustment mechanism is disposed on the base, the mounting plate is movably mounted on the moving adjustment mechanism, the first dispensing mechanism is fixedly mounted on the mounting plate, the lifting assembly is mounted on the mounting plate, and the second dispensing mechanism is movably mounted on the lifting assembly. However, when dispensing hot melt adhesive, the hot melt adhesive cannot be directly removed after dispensing. Utility Model Content

[0025] like Figure 1 As shown, a hot melt adhesive dispensing device includes a heating mechanism 1 and a fixed bracket 2. The fixed bracket 2 is connected to a fixed plate 3.

By setting the retainer 5 at the bottom of the heating mechanism 1, the retainer 5 can be opened and closed to realize the transmission and cutting off of hot melt adhesive without waiting for the hot melt adhesive and the heating mechanism 1 to cool down before removal, thus realizing hot application and hot removal of hot melt adhesive. The heating mechanism 1 is used to heat the hot melt adhesive. The rotating mechanism 6 realizes the rotation of the heating mechanism 1. The moving mechanism 7 realizes the raising and lowering of the heating mechanism 1, thereby realizing the separation and closing of the retainer 5 and the heating channel 10. The fixed plate 3 is U-shaped and is used to connect the fixed bracket 2 and the dispensing mechanism 4.

[0026] like Figure 4 and Figure 5As shown, the heating mechanism 1 includes a heating barrel lid 8 and a heating barrel wall 9. An aluminum-core polyurethane tube 24 is disposed inside the heating barrel wall 9, and hot melt adhesive is disposed inside the aluminum-core polyurethane tube 24.

[0027] The dispensing mechanism 4 includes a heating channel 10 and a dispensing valve 11. One end of the heating channel 10 is connected to the bottom of the retainer 5, and the other end is connected to the dispensing valve 11. The dispensing valve 11 is connected to the fixing plate 3. A heater is provided inside the heating channel 10. When the heating channel 10 and the heating mechanism 1 are cut off, the temperature inside the heating channel 10 is ensured to be uniform, and dispensing can continue through the dispensing valve 11.

[0028] like Figure 3 As shown, the retainer 5 includes a first connector 12 and a second connector 13. The first connector 12 is located on the second connector 13, and a connecting valve 14 is provided on the first connector 12. The connecting valve 14 is located at the bottom of the heating barrel wall 9. The second connector 13 is connected to the heating flow channel 10. The connecting valve 14 is a one-way valve. When the connecting valve 14 is closed, the preheated aluminum core polyurethane tube 24 is inserted into the heating barrel wall 9, and the heating barrel cover 8 is tightened. The first connector 12 and the second connector 13 are closed, and the end of the first connector 12 is now located inside the second connector 13. When the connecting valve 14 is opened, hot melt adhesive enters the heating flow channel 10 from the heating barrel wall 9.

[0029] like Figure 2 As shown, the rotating mechanism 6 includes a rotating cylinder 15 and a connecting plate 16. The output shaft of the rotating cylinder 15 is connected to the connecting plate 16, and a moving mechanism 7 is provided on the connecting plate 16.

[0030] The moving mechanism 7 includes a limiting bracket 17 and a mounting block 18. A lifting cylinder 19 is housed within the limiting bracket 17. The piston rod of the lifting cylinder 19 is connected to the mounting block 18. A sliding groove 20 is provided on the connecting plate 16. One end of the mounting block 18 is positioned within the sliding groove 20, and the sliding groove 20 and mounting block 18 are slidably connected. A fixing block 25 is connected to one side of the mounting block 18, and the fixing block 25 is connected to the heating barrel wall 9. The limiting bracket 17 is square and is used to house the lifting cylinder 19. The piston rod of the lifting cylinder 19 is connected to the mounting block 18. The sliding groove 20 is provided on the connecting plate 16, and the mounting block 18 is positioned within the sliding groove 20. The lifting cylinder 19 drives the mounting block 18 and the fixing block 25 to rise or fall, thereby causing the heating barrel wall 9 to rise or fall, achieving the detachment or closure of the first connector 12 and the second connector 13.

[0031] The first connector 12 and the second connector 13 are detachably connected. The first connector 12 is fitted into the second connector 13. When the connecting valve 14 is opened, the lifting cylinder 19 drives the heating barrel wall 9 to descend, and the first connector 12 is fitted into the second connector 13 to form a closed state. When the connecting valve 14 is closed, the lifting cylinder 19 drives the heating barrel wall 9 to rise, and the first connector 12 disengages from the second connector 13.

The U-shaped fixed plate 3 facilitates the connection between the fixed bracket 2 and the dispensing mechanism 4, while the L-shaped first mounting plate 21 is fixed to the connecting plate 16.

[0035] The working principle of this utility model is as follows: The output shaft of the rotary cylinder 15 drives the mounting block 18 and the fixing block 25 to rotate. The rotation of the fixing block 25 causes the heating barrel wall 9 to rotate from the vertical direction to an inclined direction with the opening facing upward. The heating barrel wall 9 is then fitted with an aluminum core polyurethane tube 24 with hot melt adhesive, and the heating barrel cover 8 is placed on top. The output shaft of the rotary cylinder 15 drives the mounting block 18 and the fixing block 25 to rotate. After the fixing block 25 rotates and causes the heating barrel wall 9 to rotate to the vertical position, the piston rod of the lifting cylinder 19 drives the mounting block 18 and the fixing block 25 to descend. The fixing block 25 and the heating barrel wall 9 descend to the first joint 1. With the second connector 13 closed, open the connecting valve 14 to start heating the hot melt adhesive. The hot melt adhesive enters the heating channel 10 from the heating barrel wall 9 and is dispensed through the dispensing valve 11. When the dispensing is complete, close the connecting valve 14. The piston rod of the lifting cylinder 19 drives the mounting block 18, the fixing block 25, and the heating barrel wall 9 to rise, and the first connector 12 and the second connector 13 disengage. The output shaft of the rotating cylinder 15 drives the mounting block 18, the fixing block 25, and the heating barrel wall 9 to rotate to an upward tilting direction. Open the heating barrel cover 8 and use heat-resistant gloves to remove the aluminum core polyurethane tube 24 to achieve disassembly.
