DETAILED DESCRIPTION

[0026] The present invention will be further described in detail below with reference to the accompanying drawings.

[0027] This specific embodiment is merely an explanation of the present invention and is not intended to limit the present invention. After reading this specification, those skilled in the art may make non-creative modifications to this embodiment as needed. However, as long as such modifications are within the scope of the claims of the present invention, they are protected by patent law.

[0028] Example: Figure 1 and Figure 6 As shown, a production process of a water cooling vest includes the following steps:

[0029] Step 1: Cut the TPU sheet into three types of vest pieces: left side, right side, and back side. The left vest piece 301 and the right vest piece 302 are bilaterally symmetrical.

[0030] Step 2: Pressing a water channel on one side of the vest piece through a forming die;

[0031] Step 3: overlap the two vest pieces at the same location, align the waterways of the two vest pieces, press the two vest pieces together using a hot pressing device 1, and perform edge pressing on the edges of the vest pieces;

[0032] Step 4: Press the connecting belts onto the vest pieces, and connect the left, back, and right vest pieces in sequence through the connecting belts and buckles. Finally, connect the water routes of the three pieces through a water pipe, which uses a rubber hose.

[0033] The cross-section of the water channel is rectangular, and the depth of the water channel is 0.5-0.6 times the thickness of the vest piece. In this embodiment, the thickness of the vest piece is 1.5-2 mm.

[0034] In step 2, the forming mold is composed of an upper mold and a lower mold, wherein a convex edge matching the water channel is provided on the lower surface of the lower mold, and the convex edge is heated during forming.

[0035] In step three, before lamination, the overlapping side of the two vest pieces is preheated by a preheating device 2 so that the overlapping side of the two vest pieces is softened, making it easier to separate the two pieces after lamination.

[0036] In step three, ventilation treatment is performed at both ends of the water channel during the pressing process to prevent the water channel from being deformed or blocked during the hot pressing process and to ensure that the water channel is unobstructed.

[0037] like Figure 2 、 Figure 3 and Figure 4 As shown, the hot pressing device 1 includes a hot pressing platform 101, a fixed pressing plate 102 disposed on the hot pressing platform 101, a lifting base 106 disposed above the hot pressing platform 101, a movable pressing plate 107 fixed below the lifting base 106, a side plate 108 disposed outside the movable pressing plate 107, a first lifting actuator 110 that drives the lifting base 106 to move up and down, and a second lifting actuator 111 that drives the side plate 108 to move up and down relative to the movable pressing plate 107. The first lifting actuator 110 is mounted on a mounting base above the hot pressing platform 101 to push the lifting base 106 to move up and down.

[0038] The hot pressing platform 101 is provided with a movable platform 103, a positioning cavity 105 arranged on the movable platform 103 and matching the vest piece, and a reset component 104 that drives the movable platform 103 to move upward. The fixed pressing plate 102 is arranged in the positioning cavity 105, and the edge pressing plate 108 is provided with a pressing block 114 that presses the movable platform 103 downward.

[0039] A movable bracket 109 is installed on the lifting seat 106, and the edge holding plate 108 is installed on the movable bracket 109. The second lifting actuator 111 is installed on the lifting seat 106 to push the movable bracket 109 and the edge holding plate 108 to move up and down.

[0040] The first lifting actuator 110 and the second lifting actuator 111 are both hydraulic cylinders.

[0041] Initially, the lower end surface of the edge plate 108 is flush with the lower surface of the movable platen 107. Once the stacked vest panels are placed within the positioning cavity 105, the movable platen 107 and edge plate 108 move downward, pressing the two panels together at a temperature of 100-120°C (the specific temperature is determined by actual production conditions). Subsequently, the edge plate 108 moves downward independently, compacting the edges of the vest panels, forming a pressure edge and improving the overall sealing performance of the vest panels. As the edge plate 108 moves downward, the pressing block 114 presses downward against the movable platen 103, forcing it downward until the relief groove 117 on the inside of the movable platen 103 is positioned at the side of the vest panel. During the pressure process, the edges of the vest panels are compacted and extend outward into the relief groove 117, preventing them from adhering to the inner wall of the movable platen 103.

[0042] The lower surface of the movable pressing plate 107 is provided with a vent 112 and an exhaust port 113. Vent 112 is connected to a high-pressure air source, which is a conventional air pump. Both vent 112 and exhaust port 113 contain adsorption disks 115, which rest against the surface of the vest sheet. The lower ends of adsorption disks 115 have cavities within them. During the hot pressing process, when the movable pressing plate 107 contacts the vest sheet, the adsorption disks 115 cover the surface of the vest sheet, positioning the ports at both ends of the water channel within the two adsorption disks 115 to ventilate the water channel. Simultaneously, the pressure on the lower ends of the adsorption disks 115 causes the cavities to deform, increasing the contact area between the adsorption disks 115 and the vest sheet while also providing a buffering effect and protecting the surface of the vest sheet.

[0043] like Figure 5As shown, the preheating device 2 includes a preheating box 201, a movable platform 203 that moves horizontally in and out of the preheating box 201, a suction plate 205 disposed above the movable platform 203, a third lifting actuator 206 that drives the suction plate 205 up and down, a preheating plate 207 disposed within the preheating box 201 and between the movable platform 203 and the suction plate 205, and a heating assembly 208 disposed within the preheating plate 207. A movable track 202 is installed within the preheating box 201. The movable platform 203 is mounted on the movable track 202 via sliders or rollers. The movable platform 203 is driven to move by a chain drive or a screw mechanism. A mounting frame 204 is provided on the movable platform 203. The suction plate 205 is slidably mounted on the mounting frame 204. The third lifting actuator 206 is connected between the suction plate 205 and the mounting frame 204. The suction plate 205 is mounted with a negative pressure suction cup for adsorbing the vest piece. The preheating plate 207 is fixed horizontally within the preheating box 201. The heating assembly 208 uses a heating wire to heat the preheating plate 207. When two stacked vest sheets are conveyed onto the movable platform 203, the suction plate 205 absorbs the upper vest sheet, maintaining an appropriate distance between the upper and lower sheets. The sheet is then moved into the preheating box 201, with the preheating plate 207 positioned between the upper and lower sheets. The two sheets are heated until their surfaces are partially melted. After heating is complete, the movable platform 203 leaves the preheating box 201, re-stacks the two sheets, and then conveys them to the hot pressing device 1 for hot pressing.
