Description

Technical Field

[0001] This utility model belongs to the field of coating machinery, and in particular to a hot melt adhesive tray. Background Technology

[0002] Previously, water baths were not heated evenly because of heat exchange issues between the pot wall and the outside air, and the water near the pot wall had a lower flow rate due to greater friction with the pot sidewall. This resulted in a temperature difference between the water near the edge and the center, causing temperature differences in the hot melt adhesive and affecting the thickness and quality of the coating. Utility Model Content

[0003] To overcome the shortcomings of the existing products mentioned above, this utility model provides a hot melt adhesive tray that provides uniform heating of hot melt adhesive.

[0004] The technical solution adopted by this utility model to solve its technical problem is: The hot melt adhesive tray consists of two tightly joined upper and lower layers. The upper layer is an open-top adhesive tray 1 for holding hot melt adhesive, and the lower layer is a water bath chamber 2 for heating the hot melt adhesive in the upper adhesive tray 1. The water bath chamber 2 is a sealed structure with several partitions 3 evenly arranged inside. The partitions 3 divide the water bath chamber 2 into several chambers 4 arranged from left to right. Adjacent chambers 4 are connected by several through holes 5 cut into the bottom of the partitions 3. The two outermost chambers 4 on the left and right sides of the water bath chamber 2 are respectively connected to an inlet pipe 6 and an outlet pipe 7.

[0005] Preferably, the inlet pipe 6 and the outlet pipe 7 are both located on the lower side wall of the water bath chamber 2.

[0006] Preferably, the inlet pipe 6 and the outlet pipe 7 are connected to the outlet and inlet of a hot water heater, respectively.

[0007] Preferably, the glue tray 1 is provided with a glue inlet pipe 8 and a glue outlet pipe 9, with the glue outlet pipe 9 located at a lower position on the side wall of the glue tray 1.

[0008] Preferably, the through hole 5 has a semi-circular structure.

[0009] Preferably, adjacent chambers 4 are connected by two through holes 5 drilled at the bottom of the partition 3.

[0010] The beneficial effects of this utility model are: This utility model of a hot melt adhesive tray has an ingenious structure. Hot water enters from one side of the water bath chamber and exits from the other side. After being heated, it circulates back into the water bath chamber to heat it. During this process, due to the presence of baffles, the hot water experiences greater resistance and a slower flow rate within the water bath chamber, thus ensuring uniform heat exchange with all parts of the chamber. This guarantees that there is no temperature difference throughout the water bath chamber, ensuring uniform heating of the adhesive tray above it. Consequently, the hot melt adhesive within the tray is heated evenly, with no temperature difference between the hot melt adhesive around the edges and in the center of the tray. This ensures high-quality adhesive application, strong practicality, and is worthy of promotion. Attached Figure Description

Detailed Implementation

[0012] All features disclosed in this specification, or steps in all methods or processes disclosed herein, may be combined in any way, except for mutually exclusive features and / or steps.

[0013] Any feature disclosed in this specification (including any appended claims, abstract, and drawings) may be replaced by other equivalent or similar features for a similar purpose, unless specifically stated otherwise. That is, unless specifically stated otherwise, each feature is merely one example of a series of equivalent or similar features.

[0014] like Figure 1-3 As shown, the hot melt adhesive tray consists of two tightly joined upper and lower layers. The upper layer is an open-top adhesive tray 1 for holding hot melt adhesive, and the lower layer is a water bath chamber 2 for heating the hot melt adhesive in the upper adhesive tray 1. The water bath chamber 2 is a sealed structure with 11 partitions 3 evenly arranged inside. The partitions 3 divide the water bath chamber 2 into 12 chambers 4 arranged from left to right. Adjacent chambers 4 are connected by two through holes 5 cut into the bottom of the partitions 3. The two outermost chambers 4 on the left and right sides of the water bath chamber 2 are respectively connected to an inlet pipe 6 and an outlet pipe 7.

[0015] Both the inlet pipe 6 and the outlet pipe 7 are located on the lower side wall of the water bath chamber 2.

[0016] The inlet pipe 6 and outlet pipe 7 are respectively connected to the outlet and inlet of a hot water heater (not shown).

[0017] The glue tray 1 is provided with a glue inlet pipe 8 and a glue outlet pipe 9, with the glue outlet pipe 9 located on the lower side wall of the glue tray 1.

[0018] The through hole 5 has a semi-circular structure.

[0019] The adjacent chambers 4 are connected by two through holes 5 dug at the bottom of the partition 3.

[0020] Work process: Hot water is introduced through the inlet pipe on the left side of the water bath chamber. The hot water flows from left to right through each chamber and then exits through the outlet pipe on the right side of the water bath chamber. After being heated by the hot water heater, it is circulated back into the water bath chamber through the inlet pipe to heat the water bath chamber. During this process, due to the presence of the baffle, the hot water faces greater resistance and flows more slowly in the water bath chamber. It exchanges heat evenly with all parts of the water bath chamber, and there is no temperature difference between different parts of the water bath chamber. The hot melt adhesive in the glue tray is heated evenly, and there is no temperature difference between the hot melt adhesive around and in the middle of the glue tray.

[0021] Therefore, the hot melt adhesive tray of this utility model has an ingenious structure. Hot water can enter from one side of the water bath chamber and exit from the other side. After being heated, it is circulated back into the water bath chamber to heat the chamber. During this process, due to the presence of the baffle, the hot water faces greater resistance and flows more slowly in the water bath chamber, thus allowing for uniform heat exchange with all parts of the water bath chamber. This ensures that there is no temperature difference in any part of the water bath chamber, thereby ensuring that the overall heating temperature of the adhesive tray above it is uniform. This ensures that the hot melt adhesive in the adhesive tray is heated evenly, and there is no temperature difference between the hot melt adhesive around the edges and in the middle of the adhesive tray. This ensures the quality of adhesive application, is highly practical, and is worthy of promotion.

[0022] This invention is not limited to the specific embodiments described above. This invention extends to any new feature or combination disclosed in this specification, as well as any new method or process step or combination disclosed herein.
