Technical Field
[0001] This utility model relates to the field of plastic card production technology, and in particular to a cooling and temperature-reducing device for plastic card production. Background Technology
[0002] The cooling and heat-reducing device in plastic card production is used to quickly cool and set the plastic cards after they have been formed at high temperatures during the plastic card production process. Cooling and heat-reducing is a key step in plastic card production, which directly affects the quality, dimensional stability and production efficiency of the cards.
[0003] However, during air cooling, the airflow speed is faster and the cooling effect is better near the air outlet of the fan, while the airflow speed is slower and the cooling effect is weaker further away from the air outlet. This can easily lead to inconsistent cooling rates in different parts of the plastic card, causing problems with the card's dimensional accuracy and shape stability. While water cooling can cool the plastic card more evenly, water stains may remain on the card surface, affecting subsequent processing. In addition, an extra drying step is required, reducing production efficiency.
[0004] Therefore, in the case of using water cooling to cool plastic cards, although the uniformity of cooling is better than air cooling, water stains may remain on the card surface, and an additional card drying step is required, a cooling device for plastic card production can be designed to reduce its operating costs and achieve energy-saving and environmental protection effects.

[0014] The beneficial effects of this utility model are:
[0015] By configuring plastic tracks, electric valves, and tactile switches, after connecting the rigid water pipe to the water source, the plastic card that falls onto the upper part of the metal heat-conducting plate is displaced as the track composed of plastic tracks rotates. When the trigger wheel crushes the pressure plate due to the displacement of the plastic tracks, the front end of the lower end of the chain is pushed by the trigger wheel and the pressure plate. Subsequently, the front end of the upper end of the chain pushes the anti-slip block and the rigid water pipe, causing the elastic anti-backflow valve inside the anti-slip block to align with the elastic anti-backflow valve inside the diversion water tank. Then, when the tactile switch is squeezed by the trigger wheel due to the displacement of the plastic tracks, it opens the electric valve, allowing water in the rigid water pipe to pass through the rigid water pipe and electric valve, breaking through the obstruction of the elastic anti-backflow valve and entering the diversion water tank. In the diversion water tank, the water cools the metal heat-conducting plate, which in turn cools the plastic card at the upper end. The water then flows out from the front end of the diversion water tank. Simultaneously, when the anti-slip block is pushed by the chain and adheres to the rear end face of the plastic tracks, the rigid water pipe and the carriage will... Due to the friction generated on the anti-slip block, the slide moves to the side along with the plastic track plate until the slide reaches the maximum displacement distance allowed by the spring return plate. Subsequently, the trigger wheel no longer presses the tactile switch due to the displacement of the plastic track plate, the electric valve closes to block the water in the hard water pipe, and the elastic anti-backflow valve, no longer pushed by the water flow, also returns to its original position due to its own elasticity to block the water flow. Then, the trigger wheel continues to move and moves away from the front end of the pressure plate, the spring guide rod pushes the pressure plate forward to return to its original position, and the spring installed in the spring return plate also causes the slide to return to its original position. In addition, the diversion tank is equipped with a dividing strip to assist in the uniform distribution of water flow. The thermal conductivity of the plastic track plate is lower than that of the metal heat-conducting plate, so that the water in the diversion tank can carry away more heat from the metal heat-conducting plate and the plastic card. Thus, without allowing the plastic card to come into direct contact with the water, the plastic card can be in large-area contact with the metal heat-conducting plate responsible for heat exchange, so as to achieve uniform cooling over a large area and avoid water stains remaining on the surface of the card.

DETAILED DESCRIPTION
[0025] The utility model will be further explained in connection with the drawings and examples.
[0026] Please refer to Figures 1-8This utility model provides an embodiment of a cooling and heat-reducing device for plastic card production, comprising multiple plastic tracks 1; it also includes an electric valve 7 and a tactile switch 12. A metal heat-conducting plate 2 is fixedly connected to the upper end of each plastic track 1. A diversion water trough 3 is formed inside the plastic track 1. Four mutually fitting elastic anti-backflow flaps 4 are fixedly connected to the rear end of the diversion water trough 3. A trigger wheel 5 is provided at the lower end of each elastic anti-backflow flap 4. An anti-slip block 8 is provided at the upper end of the rear end of the trigger wheel 5, and four mutually fitting elastic anti-backflow flaps 4 are also fixedly connected inside the anti-slip block 8. A rigid water pipe 6 is fixedly connected to the rear end of the anti-slip block 8. An electric valve 7 is installed in the middle section of the rigid water pipe 6. A chain belt 9 is installed at the lower end of the rear end of the anti-slip block 8. The lower end of the chain belt 9 has a front... A pressure plate 10 is installed at one end, and spring guide rods 11 are fixed to the rear ends of both sides of the pressure plate 10. A tactile switch 12 is installed at the front end of the pressure plate 10. A slide 13 is provided on the outside of the electric valve 7, and a spring reset plate 14 is slidably connected to the lower end of the slide 13. The electric valve 7 is electrically connected to the tactile switch 12. When the rigid water pipe 6 is connected to the water source, the plastic card that falls on the upper end of the metal heat-conducting plate 2 will be displaced as the track composed of plastic tracks 1 rotates. When the trigger wheel 5 crushes the pressure plate 10 due to the displacement of the plastic tracks 1, the front end of the lower end of the chain belt 9 will be pushed by the trigger wheel 5 and the pressure plate 10.

Then, when the tactile switch 12 is pressed by the trigger wheel 5 due to the displacement of the plastic track plate 1, the electric valve 7 is opened by the tactile switch 12. This allows the water in the rigid water pipe 6 to pass through the rigid water pipe 6 and the electric valve 7, breaking through the obstruction of the elastic anti-backflow flap 4 and entering the diversion water tank 3. In the diversion water tank 3, the water cools the metal heat-conducting plate 2, which in turn cools the plastic card at the top. Subsequently, the water flows out from the front end of the diversion water tank 3. At the same time, when the anti-slip block 8 is pushed by the chain belt 9 and sticks to the rear end of the plastic track plate 1, the rigid water pipe 6 and the slide 13 will move to the side along with the plastic track plate 1 due to the friction generated on the anti-slip block 8, until the slide 13 moves to the spring. The maximum allowable displacement distance of the reset plate 14 is reached. Subsequently, the trigger wheel 5 no longer presses the tactile switch 12 due to the displacement of the plastic track plate 1. The electric valve 7 closes to block the water in the hard water pipe 6. The elastic anti-backflow valve 4, no longer pushed by the water flow, also resets due to its own elasticity to block the water flow. Then, the trigger wheel 5 continues to move and moves away from the front end of the pressure plate 10. The spring guide rod 11 pushes the pressure plate 10 forward to reset. The spring installed in the spring reset plate 14 also resets the slide 13. In addition, a dividing strip is provided in the diversion water tank 3 to assist in the uniform distribution of water flow. The thermal conductivity of the plastic track plate 1 is lower than that of the metal heat-conducting plate 2 so that the water in the diversion water tank 3 can carry away more heat from the metal heat-conducting plate 2 and the plastic card.

[0030] Then, when the touch switch 12 is pressed by the trigger wheel 5 due to the displacement of the plastic track shoe 1, the electric valve 7 is opened by the touch switch 12, and the water in the hard water pipe 6 flows through the hard water pipe 6 and the electric valve 7 to break through the resistance of the elastic anti-backflow flap 4 into the shunt water tank 3, and then cools the metal heat-conducting plate 2 in the shunt water tank 3, and the metal heat-conducting plate 2 in turn cools the plastic card at the upper end, and then the water flows out of the front end of the shunt water tank 3 and flows into the inner ring water tank 23, the outer ring water tank 24 and the vertical tank 25 through the derived nozzle 18, and then flows into the water collecting cabin 26 and is discharged through the drain pipe 27;
[0031] At the same time, when the anti-skid block 8 is attached to the rear end surface of the plastic track shoe 1 due to being pushed by the chain belt 9, the hard water pipe 6 and the sliding frame 13 will be displaced to the side end together with the plastic track shoe 1 due to the friction force generated on the anti-skid block 8, until the sliding frame 13 is displaced to the maximum displacement distance allowed by the spring return disc 14;

[0033] In addition, a partition is arranged in the shunt water tank 3 to assist the uniform distribution of water flow, the heat conduction coefficient of the plastic track shoe 1 is lower than that of the metal heat-conducting plate 2 so that more heat from the metal heat-conducting plate 2 and the plastic card can be taken away by the water in the shunt water tank 3, the extension angle 17 is used to cooperate with the metal heat-conducting plate 2 to reduce the probability of the plastic card falling into the gap between the adjacent two plastic track shoes 1 when leaving the track, and the motor 21 rotates the track wheel 19 through the output shaft, the coupling and the rotating shaft, and the track wheel 19 in turn rotates the track composed of the plastic track shoes 1.
[0034] Through the above steps, by setting up the plastic track 1, electric valve 7, and tactile switch 12, the rigid water pipe 6 can be connected to the water source. The plastic card that falls onto the upper end of the metal heat-conducting plate 2 will be displaced as the track composed of the plastic track 1 rotates. When the trigger wheel 5 crushes the pressure plate 10 due to the displacement of the plastic track 1, the front end of the lower end of the chain belt 9 will be pushed by the trigger wheel 5 and the pressure plate 10. Subsequently, the front end of the upper end of the chain belt 9 will push the anti-slip block 8 and the rigid water pipe 6, causing the elastic anti-backflow valve 4 inside the anti-slip block 8 to interact with the elastic anti-backflow valve in the diversion water tank 3.
