Description

Technical Field

[0001] The utility model relates to the technical field of industrial production equipment, in particular to a rapid cooling device for hot melt adhesive of a bonding machine. Background Technique

[0002] In industrial production, as an important bonding material, hot melt adhesive is widely used in many fields such as clothing, leather, shoe materials, packaging, automotive interiors, furniture manufacturing, etc. due to its advantages of rapid curing, environmental protection and pollution-free, high bonding strength, etc. During the bonding process of hot melt adhesive, it usually needs to be heated to a molten state first, and then evenly coated on the surface of the material to be bonded through a coating device. After the hot melt adhesive is coated, it needs to be quickly cooled and cured to form a firm bonding effect.

[0003] However, most traditional hot melt adhesive cooling methods are through air cooling. Although it can cool the product to a certain extent, during the air cooling process, the heat on the product will be blown out into the surrounding air and dissipated, resulting in a certain amount of heat remaining in the surrounding air of the equipment. This makes the fan easy to absorb the remaining hot air around the equipment and blow it back onto the product again, resulting in a slow cooling speed of the product. At the same time, the air supply uses a fixed and single air outlet, which will cause uneven air supply, often resulting in an unsatisfactory cooling effect, affecting the bonding quality and production effect of the product. Therefore, the applicant proposes a rapid cooling device for hot melt adhesive of a bonding machine to solve the above problems. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a rapid cooling device for hot melt adhesive of a bonding machine to solve the problems raised in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A rapid cooling device for hot melt adhesive of a bonding machine, including a chassis, a conveyor assembled on the top of the chassis, and a cooling mechanism assembled on the top of the conveyor;

[0006] The cooling mechanism includes a protective cover fixedly installed on the top of the conveyor, a cooling box fixedly installed at the rear end of the protective cover, an air supply pipe penetrating through the cooling box and fixedly installed at the rear end of the protective cover, a plurality of heat conduction pipes fixedly installed on the inner wall of the cooling box and arranged at equal intervals, the heat conduction pipes extend into the air supply pipe, a return pipe and a water suction pipe are respectively communicated with one side of the cooling box, one end of the air supply pipe extends into the protective cover and is rotatably installed with a turntable, and a plurality of first air outlets and second air outlets distributed in an annular array are respectively communicated with the bottom of the turntable.

[0007] Preferably, two symmetrically distributed electric push rods are fixedly installed on both sides of the protective cover, and a pressure roller is rotatably installed between the output shafts of the two electric push rods.

[0008] Preferably, a water injection port is communicated with the top of the cooling box, and a drain port is communicated with the bottom of the cooling box.

[0009] Preferably, the air supply pipe and the turntable are rotatably installed through a rotating shaft, and through holes are uniformly formed on the surface of the heat conduction pipe.

[0010] Preferably, a blower is fixedly installed inside the chassis, and the air outlet end of the blower is communicated with the air supply pipe.

[0011] Preferably, a water pump is fixedly installed inside the chassis and on one side of the blower. The water suction end of the water pump is communicated with a water suction pipe, and the water outlet end of the water pump is communicated with a return pipe.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows: for this hot melt adhesive rapid cooling device of the bonding machine,

[0013] a cooling mechanism is provided, which enables the outside air to flow through the air supply pipe and pass through the cooling box. Through the cooling water in the cooling box, the air in the air supply pipe can be cooled. With the cooling water filling the inside of the heat conduction pipe, the heat in the air in the air supply pipe can be quickly absorbed, reducing the air temperature in the air supply pipe, improving the cooling speed of the product, effectively avoiding the situation that the remaining heat in the outside air is absorbed and blown onto the product, resulting in a slow cooling speed. At the same time, through the mutual cooperation between the first air outlet head and the second air outlet head, the second air outlet head can directly blow the wind onto the surface of the product. Since the first air outlet head is inclined, the reaction force generated when the wind is blown can drive the turntable to rotate, creating a spiral dynamic blowing effect of the air flow, enabling the wind to be blown onto the product surface more evenly and improving the cooling effect.

[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0022] Please refer to Figure 1-6 , the present invention provides a technical solution: a rapid cooling device for hot melt adhesive of a bonding machine, including a machine case 3 and a conveyor 2 assembled on the top of the machine case 3, and a cooling mechanism 1 assembled on the top of the conveyor 2. The cooling mechanism 1 includes a protective cover 101 fixedly installed on the top of the conveyor 2. A cooling box 4 is fixedly installed at the rear end of the protective cover 101. An air supply pipe 104 passing through the cooling box 4 is fixedly installed at the rear end of the protective cover 101. A plurality of heat conduction pipes 402 arranged at equal intervals are fixedly installed on the inner wall of the cooling box 4. The heat conduction pipes 402 extend into the air supply pipe 104. A return pipe 105 and a water suction pipe 106 are respectively communicated with one side of the cooling box 4. One end of the air supply pipe 104 extends into the protective cover 101 and a turntable 5 is rotatably installed. A plurality of first air outlets 502 and second air outlets 503 arranged in a circular array are respectively communicated with the bottom of the turntable 5.

[0023] Based on the above structure settings, the hot melt adhesive rapid cooling device of this bonding machine is composed of a cooling mechanism 1, a conveyor 2, and a chassis 3. Among them, the conveyor 2 can conveniently convey products, enabling the products to pass through the cooling mechanism 1. Through the cooling mechanism 1, the products can be cooled evenly more conveniently, improving the cooling speed of the products. Specifically, during the working process, the products to be cooled are placed on the conveyor 2 and conveyed into the protective cover 101. The outside air is absorbed and conveyed into the air supply pipe 104, and the air flows along the air supply pipe 104. When the air passes through the cooling box 4, the cooling water in the cooling box 4 can cool the air in the air supply pipe 104. The cooling water can fill the heat conduction pipe 402, enabling the heat conduction pipe 402 to accelerate the absorption of the residual heat in the air in the air supply pipe 104, improving the cooling effect on the air, and facilitating the rapid cooling operation of the products. The cooled air can be conveyed into the turntable 5. The inside of the turntable 5 is a cavity structure, enabling the air flow to be respectively conveyed to the first air outlet 502 and the second air outlet 503 for discharge. The air outlet of the second air outlet 503 is vertically downward, which can blow the center position of the product surface. The first air outlet 502 is in an inclined state, enabling the reaction force generated when the wind blows to push the turntable 5 to rotate. Through the rotary blowing, a spiral dynamic blowing effect can be generated for the air flow, enabling the wind to be blown more evenly to the edge position of the product surface, effectively improving the uniformity during air supply and the cooling effect of the products.

[0024] Furthermore, two symmetrically distributed electric push rods 102 are fixedly installed on both sides of the protective cover 101. A pressure roller 103 is rotatably installed between the output shafts of the two electric push rods 102. Among them, through the telescopic action of the electric push rods 102, the height of the pressure roller 103 can be conveniently controlled. The pressure roller 103 can be used to conveniently roll and press the products on the conveyor 2, enabling convenient conveying operations for the products when they enter and exit the protective cover 101.

[0025] Furthermore, a water injection port 401 is connected to the top of the cooling box 4, and a drain port 404 is connected to the bottom of the cooling box 4. Among them, through the water injection port 401, the cooling water can be conveniently injected into the cooling box 4, and through the drain port 404, the cooling water can be conveniently discharged for replacement operations.

[0026] Furthermore, the air supply pipe 104 and the turntable 5 are rotatably installed through a rotating shaft 501, and through holes 403 are evenly formed on the surface of the heat conduction pipe 402. Among them, through the rotating shaft 501, the turntable 5 can be conveniently rotated, and the cooling water in the cooling box 4 can enter the heat conduction pipe 402 through the through holes 403, facilitating the absorption of the heat in the air in the air supply pipe 104.

[0027] Further, a blower 301 is fixedly installed inside the chassis 3, and the air outlet end of the blower 301 communicates with the air supply pipe 104. Among them, the blower 301 can suck in outside air and transport it into the air supply pipe 104, facilitating the air cooling operation of the product.

[0028] Further, a water pump 302 is fixedly installed inside the chassis 3 and on one side of the blower 301. The water suction end of the water pump 302 communicates with the water suction pipe 106, and the water outlet end of the water pump 302 communicates with the return pipe 105. Among them, the water pump 302 can suck out the cooling water in the cooling tank 4 through the water suction pipe 106 and guide it back into the cooling tank 4 through the return pipe 105, enabling the cooling water to circulate inside the cooling tank 4, keeping the cooling water in a state of relatively low temperature, and preventing the cooling water from absorbing heat and reducing the cooling effect on the air in the air supply pipe 104.
