Description

Technical Field

[0001] This utility model belongs to the technical field of automotive interior processing equipment, and specifically relates to a preheating device for the glue bucket used in a pressure plate type hot melt glue machine. Background Technology

[0002] In the production of automotive interior components, a pressure plate hot melt adhesive machine is used to heat the hot melt adhesive in the glue tank. The heated hot melt adhesive is then sprayed onto the armrests and upper components and bonded to the skin. During the production process, the hot melt adhesive needs to be heated for more than half an hour to melt before it can be used. Multiple buckets of hot melt adhesive are needed for continuous production for a day. If each bucket of hot melt adhesive is heated temporarily when production is needed, it will cause unnecessary downtime during the production process and affect the production cycle.

[0003] The invention disclosed in application number CN201810807447.8 is "A device for supplying unmelted hot melt adhesive blocks". This invention includes a feeding port, a preheating and insulation device, a vent, a steel pad, a handle, an opening and closing door, a latch, and a feeding funnel. The feeding funnel is embedded in the left end of the upper surface of the preheating and insulation device. The steel pad is welded to the lower end of the preheating and insulation device. The vent is embedded in the upper end of the front of the preheating and insulation device. The latch is welded to the left end of the opening and closing door, which is hinged to the left end of the front of the preheating and insulation device via the latch. This invention uses a preheating and insulation device to preheat the hot melt adhesive blocks before supplying them, keeping the temperature between the solidification point and the melting point. This allows the hot melt adhesive blocks to quickly reach their melting point temperature upon entering the hot melt glue machine, shortening the melting time, improving melting efficiency, ensuring the glue supply speed, and preventing material interruption during glue application. However, the preheating and heat preservation device described in this invention consists of an axial conversion structure, a groove structure, a motor drive structure, a mating wheel structure, a material supply and output structure, a gear transmission structure, a preheating treatment structure, and a device housing. Its structure is complex and not suitable for heating the hot melt adhesive in the glue bucket using a pressure plate type hot melt glue machine.

[0004] The applicant disclosed a "preheating device for hot melt adhesive in automotive interior processing" in utility model application number CN202120454694.1. This utility model has a lifting cylinder mounted on a base, a crossbeam mounted on the upper end of the piston rod of the lifting cylinder, a connecting column mounted on the crossbeam, an upper melting plate connected to the lower end of the connecting column, a lower melting plate connected below the upper melting plate, a sealing ring installed in the annular groove formed between the upper and lower melting plates, an intake / exhaust valve body mounted on the upper melting plate, a ball valve mounted on one side of the intake / exhaust valve body, a switching cylinder connected to the handle of the ball valve, and the tail end of the switching cylinder hinged to the connecting rod of the switching cylinder. Although this invention can preheat the hot melt adhesive in the glue container in advance, preventing downtime caused by the melting time required for temporary heating of the hot melt adhesive, the structure of this invention includes an upper... The dispensing tray, lower dispensing tray, and suction / exhaust valves are used to preheat the hot melt adhesive in the glue container. The container needs to be opened to expose the hot melt adhesive to air before operating the preheating device. The dispensing tray is raised and lowered to preheat the hot melt adhesive in the container. When the preheating device descends to the surface of the hot melt adhesive, the suction / exhaust valves must vent. After preheating, when the preheating device is lowered to remove the glue container, the suction / exhaust valves must be vented. However, exposing the hot melt adhesive to air and heating it will cause an oxidation reaction. The oxidized hot melt adhesive will clog the suction / exhaust valve pipes, preventing the valves from opening and closing properly. This will prevent the preheating device from rising and falling normally, and the preheated glue container cannot be properly placed in or removed, thus affecting preheating and causing unnecessary downtime during production. Utility Model Content

[0005] The problem this invention aims to solve is to overcome the shortcomings of existing technologies, address the issues of oxidation reactions caused by heating hot melt adhesives exposed to air, and the unnecessary downtime during production. To address this, it provides a simple preheating device for the glue tank of a pressure plate type hot melt adhesive machine, which preheats the glue tank during automotive interior trim production. This device transfers heat to the hot melt adhesive, thus improving production efficiency.

[0006] The technical solution adopted by this utility model includes a base, on which a galvanic barrel centering chassis is installed. Fixed heating half-circle fixing brackets are welded to the left and right sides of the galvanic barrel centering chassis on the base. A fixed heating half-circle is fixedly connected to the fixed heating half-circle brackets. The rear half of a hinge is installed on the left side of the fixed heating half-circle, and a locking hook is installed on the right side of the fixed heating half-circle. A movable heating half-circle is connected to the front half of the hinge. Movable heating half-circle brackets are installed on the left and right sides of the movable heating half-circle. A supporting caster wheel is installed at the lower end of the movable heating half-circle bracket. A locking ring is installed on the right side of the movable heating half-circle, and a movable heating half-circle handle is also installed on the right side of the movable heating half-circle.

[0007] A fixed heating half-circle over-temperature protection switch and a fixed heating half-circle temperature sensor are installed on the fixed heating half-circle, and a moving heating half-circle over-temperature protection switch and a moving heating half-circle temperature sensor are installed on the moving heating half-circle.

A groove for the fixed heating half-circle is provided in the middle of the fixed heating half-circle, and a groove for the moving heating half-circle is provided in the middle of the moving heating half-circle.

[0009] Compared with existing technologies, this utility model eliminates the need to open the glue bucket lid and remove the hot melt adhesive packaging bag during use, avoiding oxidation caused by exposure to air. Simply open the locking buckle, hold the heating handle half a turn to open the heating half-turn, install the new glue bucket, hold the heating handle half a turn to close the heating half-turn, lock the buckle, and begin preheating the new glue bucket. After preheating, open the locking buckle, hold the heating handle half a turn to open the heating half-turn, remove the preheated new glue bucket, remove the lid of the preheated glue bucket, and open the hot melt adhesive packaging bag. It can then be directly used in a pressure plate hot melt adhesive machine. This utility model allows for preheating of the glue bucket used in the pressure plate hot melt adhesive machine during automotive interior trim production, thus preheating the hot melt adhesive in the glue bucket and avoiding downtime caused by temporary heating of the hot melt adhesive or malfunctions of the preheating device itself, thereby improving production cycle time and efficiency.

[0013] like Figures 1-5 As shown, the technical solution adopted by this utility model includes a base 1, on which a glue bucket centering base 2 for determining the fixed installation position of the glue bucket is installed. On the left and right sides of the glue bucket centering base 2 on the base 1, a heating half-circle bracket 13 for installing the heating half-circle is welded. A heating half-circle 10 is fixedly connected to the heating half-circle bracket 13 with connecting screws 23. A heating half-circle over-temperature protection switch 11 and a heating half-circle temperature sensor 12 are installed on the heating half-circle 10. The rear half 4-1 of the hinge 4 is installed on the left side of the heating half-circle 10, and a locking mechanism is installed on the right side of the heating half-circle 10. The latch 7 has a hook 7-1. The front half of the hinge 4-2 of the hinge 4 is connected to a movable heating half-ring 3. Movable heating half-ring brackets 14 are installed on the left and right sides of the movable heating half-ring 3 respectively. A support caster 9 for supporting the movable heating half-ring 3 when the movable heating half-ring is opened and closed is installed at the lower end of the movable heating half-ring bracket 14. A movable heating half-ring over-temperature protection switch 5 and a movable heating half-ring temperature sensor 6 are installed on the movable heating half-ring 3. A locking ring 7-2 of the locking latch 7 is installed on the right side of the movable heating half-ring 3. A movable heating half-ring handle 8 is also installed on the right side of the movable heating half-ring 3. Specifically, the movable heating half-ring handle 8 is threadedly connected to the movable heating half-ring 3.

[0014] Both the fixed heating half-circle 10 and the moving heating half-circle 3 are semi-circular. The fixed heating half-circle 10 has a groove 10-1 in the middle to avoid the handle 22-1 of the glue bucket 22 when in use. The moving heating half-circle 3 has a groove 3-1 in the middle to avoid the handle of the glue bucket when in use.

[0015] Both the fixed heating half-circle 10 and the dynamic heating half-circle 3 are cast from aluminum alloy with heating tubes inside.

[0016] like Figure 6 and Figure 7 As shown, during use, a control cabinet 21 is installed on the rear side of the base 1. The control cabinet 21 is equipped with a stop button 15, a start button 16, a constant heating half-circle thermometer 17, a dynamic heating half-circle thermometer 18, a power indicator light 19, and a running indicator light 20. The constant heating half-circle over-temperature protection switch 11 and constant heating half-circle temperature sensor 12 installed on the constant heating half-circle 10, and the dynamic heating half-circle over-temperature protection switch 5 and dynamic heating half-circle temperature sensor 6 installed on the dynamic heating half-circle 3 are electrically connected to the relevant electrical components on the control cabinet 21. A new glue bucket 22 is inserted into the circular heating ring composed of the constant heating half-circle 10 and the dynamic heating half-circle 3. This allows the hot melt adhesive in the glue bucket of the pressure plate hot melt glue machine to be preheated in the automotive interior manufacturing process. Furthermore, during use, it is not necessary to open the top cover of the glue bucket used by the pressure plate hot melt glue machine or remove the hot melt adhesive packaging bag.
