Description

Technical Field

[0001] The utility model relates to the technical field of plastic production, in particular to a cooling device for producing plastic plates. Background Art

[0002] During the plastic production process, a cooling device is often required to cool the newly produced plastic sheets. Existing plastic sheet cooling devices generally use water cooling to cool the produced plastic. For example, Publication No. CN213198470U discloses a cooling device for plastic production, which includes a first housing, a second housing fixedly connected to the upper surface of the first housing, and two partitions disposed within the second housing, with a bearing being engaged on the right side of the left partition. This plastic production cooling device comprises a threaded rod, a motor, a bearing, and a rotating shaft. A worker controls the rotation of the motor, which drives the mounting plate through the rotating shaft, threaded rod, and movable and connecting rods. The mounting plate then drives the movement of a fan and a scraper. Because the scraper has absorbent cotton on its lower surface, the absorbent cotton can clean water droplets from the surface of the plastic sheet. The worker controls the operation of the fan, which causes it to dry out any residual moisture on the plastic sheet. This device can rapidly cool the plastic sheet and dry out the moisture on the plastic sheet.

[0003] However, during the filling of plastic plates, due to the certain difference in molecular orientation parallel to the flow direction and perpendicular to the flow direction, the surface of the plastic cools and solidifies first, which will form a temperature difference between the surface and the interior of the plastic, causing internal stress in the plastic part. After demolding, the heat inside the plastic part is not completely dissipated, and the residual thermal stress will cause the plastic part to lose external pressure, resulting in uneven shrinkage of the plastic and warping deformation. To address this defect, a cooling device for plastic plate production has been developed. Utility Model Content

When the plastic plate is cooled, the cylinder lifts the pressing plate and controls the blowing mechanism 8 to blow away the moisture on the upper surface of the plastic plate 5.

[0027] In one embodiment, Figures 1 to 4As shown, the water spraying mechanism 7 is divided into two groups and is installed on the left and right sides of the interior of the box body. The water spraying mechanism 7 includes a nozzle 701 and a connecting pipe 702. The nozzle 701 is symmetrically installed on both sides of the inner wall of the box body 1. The nozzle 701 is installed at an angle so that the water flow can be evenly sprayed on the upper end of the pressing plate 4. One end of the nozzle 701 is connected to the connecting pipe 702, and the connecting pipe 702 is fixed to the inner wall of the box body 1 through a fixing plate. The connecting pipe 702 passes through the support plate 6 and is connected to the water pump 706 at the other end. One end of the water pump 706 is connected to one side of the water tank 705. The upper end of the other side of the water tank 705 is provided with an inlet pipe 707 and the lower end is provided with a water outlet pipe 708. The water in the water tank 705 is replaced regularly to avoid water contamination and spraying on the plastic plate 5, thereby affecting the surface quality of the plastic plate 5. A funnel 703 is provided at the upper end of the water tank 705 , and the funnel 703 is fixed to the lower end surface of the support plate 6 . A filter layer 704 is installed in the middle of the funnel 703 , and the filter layer can filter out some impurities brought on the plastic plate.

[0028] In one embodiment, Figures 1 to 4 As shown, the blowing mechanism 8 includes a motor 801, a bracket 805, a screw 804, a slider seat 803, a connecting air pipe 807, an air blowing pipe 806, and a blower 808. The motor 801 is horizontal and installed on the left and right sides of the side wall of the box body 1. The output end of the motor 801 is connected to the screw 804 through a coupling. One end of the screw 804 is installed on the vertical plate 802 through a bearing seat, and the other end of the screw 804 is installed on the side wall of the box body 1 through a bearing seat. The slider seat 803 is installed on the screw 804, and the bracket 805 is installed between the slider seats 803. The lower end of the bracket 805 is installed with an elastic buckle. The air blowing pipe 806 is fixed to the lower end of the bracket 805 by the elastic buckle, and a number of air outlets 809 are evenly distributed on the lower end of the air blowing pipe 806, and the air outlet 809 is installed at an angle. One end of the air blowing pipe 806 is provided with a connecting pipe 702 , and the other end of the connecting pipe 702 is connected to the blower 808 . The blower 808 is fixed to the upper end surface of the support plate 6 and fixed to the side surface of the box body 1 .

[0029] In one embodiment, Figures 1 to 4 As shown, a plurality of filter holes 601 are evenly arranged in the middle of the support plate 6 , a water trough 602 is arranged around the filter holes 601 , and the filter holes 601 are evenly distributed at the four corners of the water trough 602 .

[0030] The operation process of the cooling device for plastic plate production of the utility model is as follows: the plastic plate 5 is placed on the support plate 6, the cylinder 3 is controlled to place the pressing plate 4 on the plastic plate 5, and then the water pump 706 is turned on, and water is evenly sprayed on the pressing plate 4 through the nozzle 701. The plastic plate 5 is cooled by heat conduction between the water flow and the pressing plate 4. Since the upper surface of the plastic plate 5 is subjected to the compression effect of the external force during the cooling process, the warping and deformation of the plastic plate under the action of internal stress is avoided, thereby ensuring the quality of the product. After the plastic part 5 cools, the cylinder 3 retracts, lifting the pressing plate 4. The motor 801 is started, and the screw 804 drives the slider seat 803 forward. The slider seat 803 is fixed with a bracket 805. The lower end of the bracket 805 is provided with an air blower 806. The air blower 806 moves forward under the drive of the slider seat 803. The air blower 806 is connected to the blower 808. The blower 808 is started, and air is blown out from the air blower 809 through the air blower 806, blowing off the water on the top and sides of the plastic plate 5. The water on the plastic plate 5 can flow into the funnel 703 through the water tank 602 and the filter hole 601, and then enter the water tank 705 through the filter layer 704, so that the water can be recycled and save water. When the water in the water tank 705 is seriously polluted, the water tank 705 is equipped with a water inlet pipe 707 and a water outlet pipe 708 for replacement. The plastic plate 5 is removed from the support plate 6. When the slider seat 803 retreats, the air outlet 809 on the air blowing pipe 806 blows away the moisture on the support plate 6, so that the support plate 6 is in a dry state before the next plastic plate 5 is placed.
