[0006] The above technical purpose of the utility model is achieved through the following technical solutions: a composite fabric hot melt bonding device, comprising a frame, a bonding box fixed to the upper end of the frame and used for bonding fabrics, and a conveyor belt arranged on the frame, a cooling box is fixed to the side wall of the bonding box, an air inlet is penetrated through the upper surface of the cooling box, a heat dissipation fan is fixed to the top wall of the cooling box near the air inlet, a cooling component for refrigeration is installed on the cooling box, the cooling component comprises a water storage tank fixed to the side wall of the cooling box, a circulating pump fixed and connected to the side wall of the water storage tank, a cold water pipe fixed and connected to the water outlet of the circulating pump, and a refrigerator arranged on the cold water pipe, the cold water pipe penetrates the side wall of the cooling box and extends into the cooling box, and the end of the cold water pipe away from the circulating pump is fixed and connected to the side wall of the water tank away from the circulating pump.

[0007] By adopting the above technical scheme, the fabric enters the cooling box after hot-melt bonding in the bonding box, and the staff turns on the circulation pump and the cooling fan to allow the water in the water storage tank to enter the cold water pipe and circulate. The refrigerator cools the water in the cold water pipe, and the cooling fan blows the cold air emitted by the cold water flowing through the cold water pipe to the composite fabric in the cooling box, thereby quickly reducing the temperature of the composite fabric and reducing the probability of scalding the staff due to excessive temperature of the composite fabric.

[0020] Furthermore, a plurality of heat exchange holes are formed through one side of the upper surface of the protective shell close to the refrigerator.

[0021] By adopting the above technical solution, the heat exchange holes have a heat dissipation effect on the inside of the protective shell, which is beneficial to the rapid heat exchange between the refrigerator and the external air.

DETAILED DESCRIPTION

[0030] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application; obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments in the present application without making creative work are within the scope of protection of the present application.

[0031] like Figure 1-3 As shown, an embodiment of the present application discloses a composite fabric hot melt bonding device, including a frame 1, a bonding box 2, a conveyor belt 3, a cooling box 4, a heat dissipation fan 5 and a cooling component 6.

[0032] The frame 1 is set on the ground, and the frame 1 is used to carry the device. The gluing box 2 is a gluing box 2 commonly used in the prior art and suitable for this embodiment. The gluing box 2 is fixed to the upper end of the frame 1 and is used to glue the fabric. The conveyor belt 3 is set on the frame 1 and is used to convey the fabric. The cooling box 4 is a rectangular parallelepiped structure, and the two ends of the cooling box 4 are connected. The cooling box 4 is fixed on the side wall of the gluing box 2, and an air inlet 41 is opened through the upper surface of the cooling box 4. The heat dissipation fan 5 is fixed to the inner top wall of the cooling box 4, and the heat dissipation fan 5 is set at a position close to the air inlet 41.

[0033] The cooling component 6 is installed on the cooling box 4 for cooling. The cooling component 6 includes a water tank 61, a circulation pump 62, a cold water pipe 63 and a refrigerator 64. The water tank 61 is a rectangular box structure, and the water tank 61 is fixed on the side wall of the cooling box 4. The circulation pump 62 is a circulation pump 62 commonly used in the prior art and applicable to the present embodiment, and the circulation pump 62 is fixed and connected to the side wall of the cooling box 4. The cold water pipe 63 is fixed and connected to the water outlet of the circulation pump 62, and the cold water pipe 63 passes through the side wall of the cooling box 4 and extends into the cooling box 4. The end of the cold water pipe 63 away from the circulation pump 62 is fixed and connected to the side wall of the water tank away from the circulation pump 62. The refrigerator 64 is a refrigerator 64 commonly used in the prior art and applicable to the present embodiment, and the refrigerator 64 is arranged on the cold water pipe 63.

[0034] After the fabric is hot-melt bonded in the bonding box 2, it enters the cooling box 4. The staff turns on the circulation pump 62 and the cooling fan 5 to allow the water in the water storage tank 61 to enter the cold water pipe 63 and circulate. The refrigerator 64 cools the water in the cold water pipe 63. The cooling fan 5 blows the cold air emitted by the cold water flowing through the cold water pipe 63 to the composite fabric in the cooling box 4, thereby quickly reducing the temperature of the composite fabric and reducing the probability of scalding the staff due to the high temperature of the composite fabric.

[0035] In order to reduce the probability of external dust and debris entering the cooling box 4 through the air inlet 41, a filter screen 7 is provided on the inner wall of the air inlet 41. The filter screen 7 plays a filtering and protective role on the air inlet 41, thereby reducing the probability of external dust and debris entering the cooling box 4 through the air inlet 41 and contaminating the composite fabric.

[0036] In order to enhance the cooling effect on the composite fabric, a plurality of heat dissipation holes 42 are opened through the bottom of the cooling box 4. The cold air blown toward the composite fabric by the heat dissipation fan 5 discharges the heat emitted by the composite fabric through the heat dissipation holes 42, which is beneficial to the air circulation in the cooling box 4, thereby enhancing the cooling effect on the composite fabric.

[0037] In order to improve the overall cooling effect of the composite fabric, the inner wall of the cooling box 4 is rotatably connected to a plurality of upper conveying rollers 8 that are rollably connected to the lower surface of the composite fabric, and the inner wall of the cooling box 4 is rotatably connected to a plurality of lower conveying rollers 9 that are rollably connected to the upper surface of the composite fabric. The plurality of upper conveying rollers 8 and the plurality of lower conveying rollers 9 are staggered up and down. Since the plurality of upper conveying rollers 8 and the plurality of lower conveying rollers 9 are staggered up and down, the composite fabric is staggered up and down with the plurality of upper conveying rollers 8 and the plurality of lower conveying rollers 9, which prolongs the cooling time of the heat dissipation fan 5 and the cooling component 6 for the composite fabric, thereby improving the overall cooling effect of the composite fabric.

[0038] In order to reduce the probability of the composite fabric adhering to the upper conveying roller 8 or the lower conveying roller 9, the outer wall of each upper conveying roller 8 and the outer wall of each lower conveying roller 9 are provided with an anti-stick coating (not shown in the figure). The anti-stick coating is made of polytetrafluoroethylene non-stick coating, and its material has excellent anti-stick properties, thereby reducing the probability of the composite fabric adhering to the upper conveying roller 8 or the lower conveying roller 9 after hot-melt bonding.

[0039] In order to improve the stability of the cold water pipe 63, a support rod 10 is fixed to the inner wall of the cooling box 4 away from the water storage tank 61, and a fixing ring 11 is fixed to the side wall of the support rod 10. The fixing ring 11 is sleeved on the cold water pipe 63. The support rod 10 and the fixing ring 11 support and reinforce the cold water pipe 63, reducing the probability of the cold water pipe 63 shaking, thereby improving the stability of the cold water pipe 63.

[0040] In order to protect the cooling component 6, a protective shell 12 for covering the cooling component 6 is fixed to the side wall of the cooling box 4. The protective shell 12 protects the cooling component 6 and reduces the probability of damage to the cooling component 6 under the action of external force.

[0041] In order to facilitate heat exchange between the refrigerator 64 and the external air, a plurality of heat exchange holes 121 are opened through one side of the upper surface of the protective shell 12 close to the refrigerator 64. The heat exchange holes 121 have a heat dissipation effect for the inside of the protective shell 12, thereby facilitating rapid heat exchange between the refrigerator 64 and the external air.

[0042] The operating principle of a hot-melt bonding device for composite fabrics in the present embodiment is as follows: after the fabrics are hot-melt bonded through the bonding box 2, they enter the cooling box 4. The staff turns on the circulation pump 62 and the cooling fan 5, so that the water in the water storage tank 61 enters the cold water pipe 63 and circulates. The refrigerator 64 cools the water in the cold water pipe 63. The cooling fan 5 blows the cold air emitted by the cold water flowing through the cold water pipe 63 toward the composite fabrics in the cooling box 4, thereby quickly reducing the temperature of the composite fabrics and reducing the probability of scalding the staff due to excessive temperature of the composite fabrics.

[0043] The above is only a preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
