Description

Technical Field

[0001] The utility model relates to the technical field of plastic pipe cooling, and more specifically, to a cooling device for shaping PVC plastic pipes. Background Art

[0002] PVC plastic pipe is primarily made of polyvinyl chloride resin, stabilizers, lubricants, and other additives, then extruded through a hot-pressing process. It is one of the earliest plastic pipe materials developed and applied, boasting strong corrosion resistance, easy bonding, low price, and a strong texture.

[0003] PVC plastic pipe cooling is a crucial process in the production process of PVC plastic pipes. Generally, when cooling PVC plastic pipes, the staff first passes the plastic pipe to be cooled through the feed port of the device into the interior of the device. When the PVC plastic pipe passes through the interior of the device, the nozzle inside the device will spray cooling water on the top of the PVC plastic pipe. When the cooling of the PVC plastic pipe is completed, one end of the PVC plastic pipe will be moved out from the discharge port of the device. However, as the length of the PVC plastic pipe moved out becomes longer and longer, and the uncooled PVC plastic pipe is softer, the PVC plastic pipe will tilt. When tilting, it will cause the uncooled part of the PVC plastic pipe to bend, so it needs to be modified and optimized. Utility Model Content

[0026] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] like Figures 1 to 6 As shown, the utility model provides a cooling device for shaping PVC plastic pipes, comprising a box body 1, with a discharge port 32 opened on one side of the box body 1;

[0028] A top plate 16 is fixedly installed on one side of the box body 1, and a bracket 2 18 and a bracket 1 17 are fixedly installed on the bottom of the top plate 16. The bracket 17 is located on one side of the bracket 2 18. A spring 19 is fixedly installed on the bottom of the top plate 16, and a movable plate 20 is fixedly installed on the bottom of the spring 19. A limiting rod 22 is fixedly installed above the movable plate 20, and the top of the limiting rod 22 passes through the upper and lower sides of the top plate 16. A limiting wheel 21 is rotatably installed on one side of the movable plate 20, and a pulley 23 is fixedly installed on the other side of the movable plate 20, and the pulley 23 is movably connected to the bracket 17.

[0029] When the staff uses it, the staff first pushes the uncooled PVC plastic pipe into the interior of the device from the feed port 31. When the PVC plastic pipe is cooled, it will pass through the middle of the two limiting wheels 21. When the PVC plastic pipe passes through the middle of the two limiting wheels 21, the spring 19 will generate a downward force on the movable plate 20. When the movable plate 20 generates a downward force, the limiting rod 22 will have a downward force. When the limiting rod 22 and the movable plate 20 have a downward force at the same time, the limiting wheel 21 will have a downward moving force. As the limiting wheel 21 has a downward force, the cooled PVC plastic pipe will be limited to avoid bending.

[0030] By pushing the uncooled PVC plastic pipe into the interior of the device from the feed port 31, when the PVC plastic pipe is cooled, it will pass between the two limiting wheels 21, and the spring 19 will generate a downward force on the movable plate 20, so that the limiting wheel 21 has the force to move downward, thereby limiting the cooled PVC plastic pipe. Compared with the traditional device, the device limits the formed PVC plastic pipe to avoid the phenomenon of bending in the middle of the PVC plastic pipe due to excessive weight, thereby improving the working efficiency of the device.

[0031] Among them, a liquid measuring box 24 is fixedly installed on the right side of the box body 1, and a rotating frame 25 is hinged on the side of the liquid measuring box 24. One end of the rotating frame 25 extends to the interior of the liquid measuring box 24 and is fixedly installed with a float box 27. A pressing plate 26 is fixedly installed on one side of the other end of the rotating frame 25. A stop button 28 is fixedly installed on one side of the liquid measuring box 24. A start button 29 is fixedly installed on one side of the liquid measuring box 24, and the start button 29 is located above the stop button 28.

[0032] When the staff uses the device, the cooling water inside the device will evaporate when it encounters a hot object. When the cooling water evaporates, the cooling water inside the device will become less. When the cooling water becomes less, the water level of the cooling water will drop. When the water level drops, the float box 27 will move downward. When the float box 27 moves downward, one end of the rotating frame 25 will move downward, thereby causing the other end of the rotating frame 25 to move upward, thereby driving the pressing plate 26 to move upward. When the pressing plate 26 moves upward and touches the start button 29, the water pump will be started to inject water into the box body 1 and the liquid measuring box 24 through the water inlet pipe 30. When the water level rises, the pressing plate 26 will drop, thereby contacting the stop button 28. When the pressing plate 26 contacts the stop button 28, the water pump will stop.

[0033] The rise and fall of the cooling water level drives the float box 27 to rise and fall, thereby driving one end of the rotating frame 25 to rise and fall, and then driving the other end of the rotating frame 25 and the pressing plate 26 to fall and rise. The pressing plate 26 touches the stop button 28 and the spring 19 to control the stop and start of the water pump. Compared with traditional devices, this device can reduce the workload of the workers and improve the convenience of operation of the device by replenishing the cooling water inside the device.

[0034] Among them, a base 2 is fixedly installed at the bottom inside the box body 1, a telescopic rod 3 is fixedly installed above the base 2, a bottom nozzle 4 is fixedly installed above the telescopic rod 3, a roller 5 is rotatably installed above the bottom nozzle 4, one end of the bottom of the bottom nozzle 4 is connected to a hose 6, a water pump 7 is fixedly installed at the bottom inside the box body 1, a hose 2 8 is fixedly installed on one side of the water pump 7, and one end of the hose 6 is fixedly connected to one end of the water pump 7.

[0035] When the PVC plastic pipe passes over the top of the roller 5, the cooling water inside the box 1 is driven by starting the water pump 7 to be sprayed to the top of the PVC plastic pipe through the bottom nozzle 4.

[0036] Among them, the number of telescopic rod 1 3 , bottom nozzle 4 , roller 1 5 , hose 1 6 and hose 2 8 is two, totaling two groups, each group consists of a single telescopic rod 1 3 , bottom nozzle 4 , roller 1 5 , hose 1 6 and hose 2 8 , and are all arranged above the base 2 .

[0037] The design of two sets of telescopic rods 3, bottom nozzles 4, rollers 5, hoses 6, water pumps 7 and hoses 8 can improve the efficiency of cooling the PVC plastic pipe.

[0038] Among them, a telescopic rod 2 9 is fixedly installed above the base 2, a roller frame 10 is fixedly installed on one end of the telescopic rod 2 9, and a roller 2 11 is rotatably installed above the roller frame 10.

[0039] By designing the telescopic rod 29 and the roller frame 10, the middle part of the PVC plastic pipe is supported, thereby reducing the possibility of the PVC plastic pipe being bent inside the device.

[0040] Among them, the number of telescopic rod 2 9, roller frame 10 and roller 2 11 is two, totaling two groups, each group consists of a single telescopic rod 2 9, roller frame 10 and roller 2 11, and the two groups are respectively arranged on the top of the base 2 and the inner side of the box body 1.

[0041] The PVC plastic pipe is limited up and down by two sets of telescopic rods 9, roller frames 10 and rollers 11 to prevent the PVC plastic pipe from bending.

[0042] Among them, a water pump 2 12 is fixedly installed on the top of the box body 1, and a hose 3 13 is fixedly installed on one end of the water pump 2 12. One end of the hose 3 13 extends to the interior of the box body 1 and is fixedly installed with a top nozzle 14. The other end of the water pump 2 12 is fixedly installed with a hose 4 15. One end of the hose 4 15 extends to the interior of the box body 1.

[0043] By starting the water pump 2 12, the cooling water inside the box 1 is sprayed onto the top of the PVC plastic pipe through the top nozzle 14 to cool the PVC plastic pipe.

[0044] Among them, the number of water pump 2 12 , hose 3 13 , top nozzle 14 and hose 4 15 is two, and the top of each top nozzle 14 is fixedly connected to the top of the inner side of the box body 1 .

[0045] The PVC plastic pipe is cooled by designing two sets of water pumps 2 12 , hose 3 13 , top nozzle 14 and hose 4 15 , so that the cooling efficiency of the PVC plastic pipe is higher.

[0046] A feed port 31 is provided on one side of the box body 1 , and the feed port 31 is located opposite to the discharge port 32 .

[0047] The design of the feed port 31 allows the uncooled PVC plastic pipe to enter the interior of the device.

[0048] A water inlet pipe 30 is fixedly installed above the liquid testing box 24 , and one end of the water inlet pipe 30 is connected to the coolant replenishing tank.

[0049] Cooling water can enter the interior of the box body 1 and the liquid measuring box 24 through the water inlet pipe 30, thereby facilitating the replenishment of cooling water.

[0050] The working principle and use process of this utility model:

[0051] When the staff uses it, the staff first pushes the uncooled PVC plastic pipe into the interior of the device from the feed port 31. When the PVC plastic pipe is cooled, it will pass through the middle of the two limiting wheels 21. When the PVC plastic pipe passes through the middle of the two limiting wheels 21, the spring 19 will generate a downward force on the movable plate 20. When the movable plate 20 generates a downward force, the limiting rod 22 will have a downward force. When the limiting rod 22 and the movable plate 20 have a downward force at the same time, the limiting wheel 21 will have a downward moving force. As the limiting wheel 21 has a downward force, the cooled PVC plastic pipe will be limited to avoid bending.

[0052] When the staff uses the device, the cooling water inside the device will evaporate when it encounters a hot object. When the cooling water evaporates, the cooling water inside the device will become less. When the cooling water becomes less, the water level of the cooling water will drop. When the water level drops, the float box 27 will move downward. When the float box 27 moves downward, one end of the rotating frame 25 will move downward, thereby causing the other end of the rotating frame 25 to move upward, thereby driving the pressing plate 26 to move upward. When the pressing plate 26 moves upward and touches the start button 29, the water pump will be started to inject water into the box body 1 and the liquid measuring box 24 through the water inlet pipe 30. When the water level rises, the pressing plate 26 will drop, thereby contacting the stop button 28. When the pressing plate 26 contacts the stop button 28, the water pump will stop.
