[0001] The utility model relates to the technical field of PVC guardrail processing, in particular to a cooling device for PVC guardrail processing. Background Art

[0002] PVC guardrail is a kind of fence made of polyvinyl chloride (PVC) material, which is widely used in gardening, property management, public facilities and other places. Its characteristics include corrosion resistance, UV resistance, easy maintenance and installation. In the production of PVC guardrail, thermoplastic material processing is involved, such as extrusion molding. The cooling device is used to help quickly cool the thermoplastic material to its solidified state to ensure the dimensional stability and surface quality of the finished product.

[0003] In the prior art, part or the entire guardrail product is placed in a cooling trough for cooling. The water temperature in the cooling trough will gradually increase. When it reaches a certain temperature, the staff is required to change the water in the cooling trough to ensure the subsequent cooling effect of the PVC guardrail product. However, this increases the fatigue intensity of the staff and will cause improper control of the water temperature, thereby reducing the use effect of the PVC guardrail processing cooling device. Utility Model Content

[0004] The purpose of the utility model is to solve the problem that when the existing equipment is used, the cooling effect of the PVC guardrail after processing is poor due to improper water temperature control by the staff, and a cooling device for PVC guardrail processing is proposed.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical solutions: a cooling device for PVC guardrail processing, comprising an operating panel, a cooling trough fixedly installed on the top of the operating panel, two water-permeable plates fixedly installed on the inner wall of the cooling trough, a first temperature sensor fixedly installed on one side of the inner wall of the cooling trough, a cooling water tank fixedly installed on the top of the operating panel, a cooling water pipe fixedly inserted on the top of the cooling water tank, and the outer wall of the cooling water pipe is connected to the interior of the cooling trough, a water pump fixedly installed on the outer wall of the cooling water pipe, a circulating water tank fixedly installed on the top of the operating panel, and the output end of the cooling water pipe is connected to the interior of the circulating water tank.

[0006] Preferably, a controller is fixedly mounted on one side of the outer wall of the cooling tank, and one side of the outer wall of the controller is electrically connected to the outer wall of the first temperature sensor.

[0007] Preferably, two driving motors are fixedly mounted on one side of the outer wall of the cooling tank, driving rods are fixedly mounted on one side of the outer walls of the two driving motors, and outer walls of the two driving rods are movably inserted into the interior of the cooling tank.

[0008] Preferably, a plurality of stirring blades are fixedly mounted on the outer walls of the two driving rods, and a second temperature sensor is fixedly mounted on one side of the inner wall of the circulating water tank.

[0009] Preferably, a fan is fixedly installed on the top of the circulating water tank, and a dustproof net is fixedly installed on the top of the circulating water tank.

[0010] Preferably, a connecting pipe is fixedly inserted into one side of the outer wall of the circulating water tank, and the output end of the connecting pipe is connected to the interior of the cooling water tank.

[0011] Preferably, a control valve is fixedly mounted on the outer wall of the connecting pipe.

[0012] Compared with the prior art, the advantages and positive effects of the present invention are:

[0013] 1. In the utility model, after the finished PVC guardrail is cooled in the cooling trough for a period of time, the water temperature in the cooling trough will rise. Under the action of the first temperature sensor, when the internal temperature exceeds the set value, the water pump is started by the controller to make the cold water in the cooling water tank pass through the cooling trough along the cooling water pipe, and take away the heat adsorbed on the cooling water pipe, and then return to the circulating water tank, so as to reduce the temperature of the water in the cooling trough and make it within the optimal temperature range for cooling the PVC guardrail. There is no need for staff to change the water in the cooling trough, which reduces the fatigue intensity of the staff and realizes automatic temperature control, thereby improving the use effect of the PVC guardrail processing cooling device.

[0014] 2. In the present invention, two drive motors are started to drive two drive rods and multiple stirring blades to rotate and stir the water, thereby improving the fluidity of the water, avoiding uneven water temperature, and ensuring that each extruded PVC guardrail can obtain a uniform cooling effect. Secondly, the hot water enters the circulating water tank along the cooling water pipe. At this time, the fan is started to cool it, and through the action of the second temperature sensor, when the internal temperature reaches the set value, the control valve is opened to return it along the connecting pipe to the cooling water pipe, thereby realizing recycling and further improving the use effect of the PVC guardrail processing cooling device.

[0021] In order to more clearly understand the above-mentioned purposes, features and advantages of the present invention, the present invention is further described below with reference to the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features therein can be combined with each other unless there is a conflict.

[0022] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0023] Example 1: Figure 1-Figure 4 As shown, the utility model provides a cooling device for PVC guardrail processing, including an operating panel 1, a cooling trough 2 is fixedly installed on the top of the operating panel 1, two water-permeable plates 3 are fixedly installed on the inner wall of the cooling trough 2, a first temperature sensor 4 is fixedly installed on one side of the inner wall of the cooling trough 2, a cooling water tank 5 is fixedly installed on the top of the operating panel 1, a cooling water pipe 6 is fixedly inserted on the top of the cooling water tank 5, and the outer wall of the cooling water pipe 6 is connected to the interior of the cooling trough 2, a water pump 7 is fixedly installed on the outer wall of the cooling water pipe 6, a circulating water tank 8 is fixedly installed on the top of the operating panel 1, and the output end of the cooling water pipe 6 is connected to the interior of the circulating water tank 8, a controller 9 is fixedly installed on one side of the outer wall of the cooling trough 2, and one side of the outer wall of the controller 9 is electrically connected to the outer wall of the first temperature sensor 4.

[0024] The effect achieved by the entire embodiment 1 is that the newly extruded PVC guardrail is placed in the cooling trough 2 to quickly reduce its temperature, which helps to ensure that the material solidifies quickly, thereby avoiding deformation and defects. Since a first temperature sensor 4 is installed on one side of the inner wall of the cooling trough 2, and the first temperature sensor 4 is electrically connected to the controller 9, the water temperature in the cooling trough 2 is monitored by the first temperature sensor 4. When the water temperature exceeds the set value range, the water pump 7 is turned on by the controller 9 to make the cold water in the cooling water tank 5 flow along the cooling water pipe 6, and the outer wall of the cooling water pipe 6 is in the cooling trough 2, so that the heat adsorbed on the cooling water pipe 6 can be taken away, and then returned to the circulating water tank 8, thereby reducing the water temperature in the cooling trough 2 and restoring it to the optimal temperature range for cooling the PVC guardrail. During the entire process, there is no need for staff to observe the water temperature, nor is there a need for staff to change the water in the cooling trough 2 to ensure the cooling effect of the PVC guardrail product, thereby improving the use effect of the PVC guardrail processing cooling device.

[0025] Example 2: Figure 2-Figure 4 As shown, two drive motors 10 are fixedly installed on one side of the outer wall of the cooling tank 2, and a drive rod 11 is fixedly installed on one side of the outer wall of the two drive motors 10, and the outer walls of the two drive rods 11 are movably inserted into the interior of the cooling tank 2, and a plurality of stirring blades 12 are fixedly installed on the outer walls of the two drive rods 11. A second temperature sensor 13 is fixedly installed on one side of the inner wall of the circulating water tank 8, a fan 14 is fixedly installed on the top of the circulating water tank 8, a dustproof net 15 is fixedly installed on the top of the circulating water tank 8, a connecting pipe 16 is fixedly inserted on one side of the outer wall of the circulating water tank 8, and the output end of the connecting pipe 16 is connected to the interior of the cooling water tank 5, and a control valve 17 is fixedly installed on the outer wall of the connecting pipe 16.

[0026] The effect achieved by the entire embodiment 2 is that when the formed PVC guardrail product is cooled in the cooling tank 2, the two drive motors 10 are started to drive the two drive rods 11 and the multiple stirring blades 12 to rotate, thereby improving the fluidity of the water, and under the action of the two water-permeable plates 3, the multiple stirring blades 12 will not touch the finished PVC guardrail product, effectively avoiding uneven water temperature, and ensuring that each extruded PVC guardrail can obtain a uniform cooling effect. Then, when the hot water enters the circulating water tank 8 along the cooling water pipe 6, the fan 14 is started to cool the hot water in the circulating water tank 8. Since the inner wall of the circulating water tank 8 is A second temperature sensor 13 is installed, and the water temperature in the circulating water tank 8 is monitored by the second temperature sensor 13. Because the second temperature sensor 13 and the controller 9 are also electrically connected, when the water temperature reaches the original set value, the control valve 17 is opened by the controller 9, so that the water in the circulating water tank 8 that has been cooled to a certain water temperature returns to the cooling water tank 5 along the connecting pipe 16. Secondly, a dustproof net 15 is also installed on the top of the circulating water tank 8, and the dustproof net 15 covers the top of the fan 14, effectively preventing foreign matter or dust from entering the interior of the circulating water tank 8 along the fan 14, avoiding blockage of the connecting pipe 16, and further improving the use effect of the PVC guardrail processing cooling device.

[0027] Working principle: First, when producing PVC guardrails, the extruded PVC guardrail products are placed in the cooling trough 2. At this time, the two driving motors 10 installed on one side of the outer wall of the cooling trough 2 are started to drive the two driving rods 11 and multiple stirring blades 12 to stir in the cooling trough 2. Under the action of the two water-permeable plates 3, the multiple stirring blades 12 are effectively prevented from hitting the PVC guardrail products, and by improving the fluidity of the water, uneven water temperature is avoided, ensuring that each extruded PVC guardrail can obtain a uniform cooling effect. Then, under the action of the first temperature sensor 4, when the water temperature in the cooling trough 2 exceeds the set value, the water pump 7 is turned on by the controller 9, so that the cold water in the cooling water tank 5 passes through the inside of the cooling trough 2 along the cooling water pipe 6, and takes away the adsorbed water on the cooling water tank 5. The heat on the cooling pipe 6 is then returned to the inside of the circulating water tank 8, and then the fan 14 is started to cool the water in the circulating water tank 8. Through the action of the second temperature sensor 13, when the water temperature in the circulating water tank 8 drops to a certain value, the control valve 17 is opened by the controller 9 to allow the water in the circulating water tank 8 to return to the cooling water tank 5 along the connecting pipe 16. In this way, water recycling can be achieved and the effect of cooling the water in the cooling tank 2 is improved. In general, there is no need for staff to monitor the water temperature in the cooling tank 2 at all times, nor is there any need to replace the water in the cooling tank 2, which reduces the fatigue intensity of the staff and improves the cooling effect of the PVC guardrail finished product, thereby improving the use effect of the PVC guardrail processing cooling device.
