DETAILED DESCRIPTION OF THE EMBODIMENTS

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0023] Please refer to Figures 1-4 , this embodiment provides a new cooling and spraying device for PVC pipe shaping, including a base 105. A cooling box 100 is fixedly installed on the top of the base 105. A cooling tank 106 is fixedly connected to one end of the inner cavity of the cooling box 100 and located on the feeding side. A hollow block 108 is fixedly installed above the cooling tank 106 and on the inner wall surface of the cooling box 100. A plurality of groups of water spray pipes 107 are communicated with one side of the hollow block 108. The water outlet ends of the water spray pipes 107 point to the inner cavity of the cooling tank 106. A water supply assembly is communicated with the surface of the hollow block 108;

[0024] Among them, through holes for passing through the PVC pipes to be cooled and shaped are formed in both side walls of the cooling box 100 corresponding to the two ends of the cooling tank 106.

[0025] Among them, the water supply assembly includes a circulation pump 101. The circulation pump 101 is fixedly installed on the top of the base 105 and is located on one side of the cooling box 100. The water inlet end of the circulation pump 101 is communicated with a water suction pipe 112. The other end of the water suction pipe 112 is communicated with the inner cavity of the cooling box 100. The water outlet end of the circulation pump 101 is communicated with a delivery pipe 104. The other end of the delivery pipe 104 is connected to the inner cavity of the hollow block 108. Through the setting of the water supply assembly, the water source in the cooling box 100 is pumped by the circulation pump 101 into the inner cavity of the hollow block 108, and is sprayed into the cooling tank 106 through the water spray pipe 107. The PVC pipe is initially cooled by the water source flowing to the outside, so that the surface thereof is hardened and shaped. Subsequently, the water sprayed by the water spray pipe 107 further cools the PVC pipe. And during the process that the PVC pipe moves towards the discharge end, the water source flowing into the inner cavity of the cooling box 100 takes away the residual heat in the PVC pipe, thereby ensuring the cooling effect on the PVC pipe.

[0026] Furthermore, a housing 102 is embedded in the top of the cooling box 100. A spiral pipe 109 is arranged in the inner cavity of the housing 102. The water inlet end of the spiral pipe 109 is communicated with the water outlet end of the delivery pipe 104. The water outlet end of the spiral pipe 109 is communicated with the inner cavity of the hollow block 108. A plurality of groups of fans 103 are embedded in the top surface of the housing 102. The air outlet ends of the fans 103 are located in the inner cavity of the housing 102 and blow air towards the inner cavity of the cooling box 100. Through the setting of the fans 103 and the spiral pipe 109, the water stains on the surface of the PVC pipe are dried, and the water source in the spiral pipe 109 is cooled. And the time for the water source to flow out of the spiral pipe 109 is more than that of a straight pipe, thereby increasing the time for the fans 103 to cool the water source in the spiral pipe 109, and thus improving the cooling effect on the water source.

[0027] Preferably, a plurality of groups of rollers 111 for supporting the PVC pipes to be cooled and shaped are rotatably connected to the inner wall of the cooling tank 106, which facilitates the movement of the PVC pipe towards the discharge end and prevents the PVC pipe from rubbing against the cooling tank 106.

[0028] It should be noted that a filter plate 110 is fixedly connected inside the cooling box 100. The filter plate 110 is located between the water inlet end of the water suction pipe 112 and the cooling tank 106 to filter the water source and prevent impurities from being sucked into the circulation pump 101.

[0029] Further, a water receiving tray 200 is fixedly connected to the surface of the cooling box 100 and below the feeding end. The inner cavity of the water receiving tray 200 is communicated with a conduit 201, and the other end of the conduit 201 is connected to the inner cavity of the cooling box 100. The water source flowing out of the cooling tank 106 first flows into the water receiving tray 200 and then flows into the inner cavity of the cooling box 100 through the conduit 201, collecting and guiding the water source flowing out of the cooling tank 106, thus saving water and preventing waste.

[0030] Working principle;

[0031] First, an appropriate amount of water source is injected into the cooling box 100. Subsequently, the circulation pump 101 is started. The water source in the cooling box 100 enters the hollow block 108 through the water suction pipe 112 and the spiral pipe 109, and is guided by the water spray pipe 107 and sprayed into the inner cavity of the cooling tank 106. The sprayed water flows to both sides of the cooling tank 106 through the cooling tank 106. The water source flowing to the outside of the cooling tank 106 first flows into the water receiving tray 200 and then flows back into the water tank through the conduit 201. Subsequently, the fan 103 is started. Then, through the pipeline traction device, the PVC pipeline is passed through the through-port at the feeding end of the cooling box 100 to the through-port at the discharging end. The PVC pipeline is first preliminarily cooled by the water source flowing from the cooling box 100 to the water receiving tray 200. Subsequently, the water source sprayed by the water spray pipe 107 further cools the PVC pipe. And during the process of the PVC pipe moving towards the discharging end, the water source flowing into the inner cavity of the cooling box 100 takes away the residual heat in the PVC pipe. And the fan 103 dries the water stains on the surface of the PVC pipe. And during the process of drying the PVC pipe, the water source in the spiral pipe 109 that conveys water to the hollow block 108 is further cooled, thus preventing the water source temperature in the cooling box 100 from being too high and affecting the cooling speed of the PVC pipeline.

[0032] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
