Description

Technical Field

[0001] This utility model relates to a cooling device for the production of hot melt adhesive pulleys. Background Technology

[0002] Hot melt adhesive backrests are a type of material commonly used in the footwear, bag, and clothing industries, primarily to enhance the shape retention and support of products.

[0003] The cooling method for hot melt adhesive backstops directly affects their setting effect, bonding strength, and production efficiency. Below are common cooling methods and their key technical points:

[0004] Natural cooling

[0005] Natural cooling has relatively low cooling efficiency and is only suitable for thin hot melt adhesive backing. Furthermore, due to the low cooling efficiency, the hot melt adhesive backing is prone to deformation before it cures due to gravity.

[0006] Forced air cooling

[0007] Forced air cooling requires a relatively high room temperature, typically between 15 and 25 degrees Celsius. However, the unidirectional airflow of forced air cooling results in uneven cooling of the hot melt adhesive shield.

[0008] Water cooling

[0009] Water cooling is mainly divided into contact water cooling and non-contact water cooling.

[0010] Non-contact water cooling requires specialized molds, which increases costs.

[0011] Contact water cooling has lower cooling costs.

[0012] To address this, we designed a cooling device for the production of hot melt adhesive ring pulleys that enables batch cooling and improves cooling efficiency. Utility Model Content

[0013] The technical problem to be solved by this utility model is to provide a cooling device for the production of hot melt adhesive rings that can achieve batch cooling and improve cooling efficiency.

[0014] To solve the above problems, the present invention adopts the following technical solution:

[0015] A cooling device for producing hot melt adhesive ring pulleys includes a cooling tank and a lifting device. A suspended structure is supported by the lifting device. The suspended structure moves up and down with the lifting device. When moving down, the suspended structure moves into the cooling tank. When moving up, the suspended structure moves to the outside of the cooling tank. A groove is machined on the side of the cooling tank. A water inlet tank is welded to the outside of the cooling tank at the position corresponding to the groove. A water inlet pipe is connected to the outer wall of the water inlet tank. A drain valve is installed near the bottom on the outside of the cooling tank.

[0016] Preferably, the drain valve is connected to a drain pipe at its end, and an overflow pipe is installed outside the cooling tank. The end of the overflow pipe is bent downward and connected to the drain pipe. The connection position of the overflow pipe to the cooling tank is lower than the height of the trough.

[0017] Preferably, the lifting device includes a frame and a telescopic device fixed to the frame, a linear bearing is installed on the frame, the suspended structure is guided by the linear bearing, and the movable end of the telescopic device is fixed to the suspended structure.

[0018] Preferably, the telescopic device is a hydraulic telescopic rod.

[0019] Preferably, the hanging box structure includes a box body, with drainage holes evenly distributed on the upper and lower end faces of the box body. A connecting plate is welded to the top of the box body, and a guide rod is fixed through the connecting plate. The guide rod passes through the linear bearing. The movable end of the telescopic device is fixed to the connecting plate. The two ends of the box body are connected. When the cable groove corresponds to the two ends of the box body, the height of the lower end face of the box body is higher than the height of the overflow pipe.

[0020] Preferably, lateral drainage grooves are machined at the bottom positions on both sides of the box body.

[0021] Preferably, the bottom of the box has a slidable base plate, and the drainage holes are evenly distributed on the base plate.

[0022] The beneficial effects of this utility model are:

[0023] This device can carry a large number of toy bags through a hanging box structure.

Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0033] See Figure 1 , Figure 2 and Figure 3 The cooling device shown includes a cooling tank 1 and a lifting device 2. A lifting box structure 3 is supported by the lifting device 2. The lifting box structure 3 moves up and down with the lifting device 2. When moving down, the lifting box structure 3 moves into the cooling tank 1. When moving up, the lifting box structure 3 moves to the outside of the cooling tank 1. A wire groove 101 is processed on the side of the cooling tank 1. A water inlet tank 102 is welded to the outside of the cooling tank 1 at the position corresponding to the wire groove 101. A water inlet pipe 103 is connected to the outer wall of the water inlet tank 102. A drain valve 4 is installed near the bottom on the outside of the cooling tank 1.

[0034] Connect the water inlet pipe 103 to the booster water supply equipment, supply water to the water inlet tank 102 through the water inlet pipe 103, and then enter the cooling tank 1 through the cable tray 101.

[0035] This device has the following cooling modes:

[0036] The first type is immersion cooling.

[0037] The lifting device 2 lifts the box structure 3, causing the box structure 3 to move to the outside of the cooling tank, and the hot melt adhesive canopy is sent into the box structure 3. The distance between the two ends of the box structure 3 and the cooling tank 1 is less than 5mm.

[0038] The lifting device 2 is used to submerge the suspended structure 3 in water for direct water cooling, with the cooling time controlled within 10 seconds.

[0039] The second type is spray cooling.

[0040] The hot melt adhesive shield is supported by the hanging box structure 3, and the height of the hanging box structure 3 is lowered by the lifting device 2, so that the hanging box structure 3 sinks into the cooling tank 1, and the height is lower than the height of the wire trough 101. The drain valve 4 is kept open, and the water sprayed from the wire trough 101 acts on the surface of the hanging box structure 3 and enters the hanging box structure 3 to spray and cool the hot melt adhesive shield located in the hanging box structure 3.

[0041] The water cooling method described above requires the water temperature to be controlled at around 25 degrees Celsius, and the water temperature should not be lower than 20 degrees Celsius.

[0042] After the above two cooling methods cool the hot melt adhesive backing, the inside of the cable tray 101 corresponding to the hanging box structure 3 is flushed with high-speed water to flush the hot melt adhesive backing to one side of the hanging box structure 3, so that the hot melt adhesive backing can be easily removed after the hanging box structure 3 is moved to the outside of the cooling tank 1.

[0043] After cooling with water, excess moisture on the surface of the hot melt adhesive shield needs to be blown away by a high-speed fan and dried to ensure that the internal moisture evaporates.

[0044] Direct water cooling has low cooling costs.

[0045] See Figure 1 As shown, the drain valve 4 is connected to a drain pipe 41 at its end, and an overflow pipe 42 is installed outside the cooling tank 1. The end of the overflow pipe 42 is bent downward and connected to the drain pipe 41. The connection position of the overflow pipe 42 and the cooling tank 1 is lower than the height of the trough 101.

[0046] In the above technical solution, excess water can be overflowed through the overflow pipe 42, and the water discharge efficiency of the overflow pipe 42 is greater than the water inlet efficiency of the inlet pipe 103.

[0047] This ensures that the water level in the cooling tank 1 is always at the overflow pipe 42.

[0048] See Figure 1 and Figure 3 As shown, the lifting device 2 includes a frame 21 and a telescopic device 22 fixed to the frame 21. A linear bearing 23 is installed on the frame 21. The suspended structure 3 is guided by the linear bearing 23. The movable end of the telescopic device 22 is fixed to the suspended structure 3.

[0049] The telescopic device 22 is a hydraulic telescopic rod.

[0050] See Figure 3 As shown, the hanging box structure 3 includes a box body 31. Drainage holes 32 are evenly distributed on the upper and lower end faces of the box body 31. A connecting plate 33 is welded to the top of the box body 31. A guide rod 34 is fixed through the connecting plate 33. The guide rod 34 passes through the linear bearing 23. The movable end of the telescopic device 22 is fixed to the connecting plate 33. The two ends of the box body 31 are connected. When the wire groove 101 corresponds to the two ends of the box body 31, the height of the lower end face of the box body 31 is higher than the height of the overflow pipe 42.

[0051] Lateral drainage grooves 331 are machined at the bottom positions on both sides of the box body 31.

[0052] In the above technical solution, a two-section through box 31 design is adopted. After the box 31 moves upward to the outside of the cooling tank, a high-speed airflow can be blown in from one end of the box 31. The first purpose is to blow away the water, and the second purpose is to blow out the hot melt adhesive backing inside the box 31.

[0053] The vertical movement of the housing 31 is guided by a guide rod 34 in conjunction with a linear bearing 23.

[0054] The cable tray 101 can deliver water through one end of the box 31. By pressurizing, the water is sprayed out at a certain flow rate, which can spray the hot melt adhesive backing from one end to the other for easy removal.

[0055] When the height of the box 31 is lower than the cable tray 101 but higher than the overflow pipe 42, the water sprayed from the cable tray 101 enters the box 31 through the drain hole 32 to achieve spray cooling. This cooling method eliminates the need to submerge the box 31 in water, saving the time of water inlet and outlet, and avoiding prolonged soaking.

[0056] See Figure 3 As shown, the bottom of the box 31 has a sliding base plate 3331, and the drainage holes 32 are evenly distributed on the base plate 3331.

[0057] The design features a sliding base plate 3331, which is suitable for various types of toy carriers, such as those that cannot be stacked for cooling. The base plate 3331 can slide outwards to facilitate the flattening of the toy carrier.
