[0002] In the process of plastic pipe production, in order to make the pipe cool and shape well, the pipe needs to be air-cooled, so an air-cooling device is needed for plastic pipe production.

[0003] For example, the patent publication number CN215151046U is a rapid air cooling device for corrugated pipe production. It starts a double-headed motor fixed in the installation sleeve to act on the transmission rod thereon, driving the refrigeration fan to rotate. The generated cold air is increased and gathered through the air collecting tube and flows into the air transport duct at the upper end. When the wind reaches the top of the air transport duct, it enters the ventilation duct, increasing the wind transmission area.

[0004] However, during actual use of the above-mentioned air cooling device, the cold air will cool both sides of the plastic pipe, while the temperature of other parts of the plastic pipe cannot be reduced well, which may cause the plastic pipe to deform, reduce the quality of product production, and reduce the cooling rate. For this reason, the applicant proposed an air cooling device for plastic pipe production. Utility Model Content

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] With the continuous development of science and technology, in plastic production, in order to meet the needs of various facilities, it is often necessary to use plastic to make pipes. In order to increase the production rate of pipes, the pipes need to be air-cooled. Therefore, an air-cooling device for plastic pipe production is needed. In the actual use of most traditional air-cooling devices, the cold air cannot fully contact the plastic pipe, resulting in different temperatures in various parts of the plastic pipe when cooling the plastic pipe, which reduces the cooling rate of the plastic pipe. For this reason, the applicant proposes an air-cooling device for plastic pipe production.

[0022] like Figure 1-Figure 4As shown, the utility model provides a technical solution: an air cooling device for plastic pipe production, comprising an air cooling base 1, a cooling mechanism 2 is fixed to the top of both ends of the air cooling base 1, the cooling mechanism 2 comprises a protection tube 201, openings are respectively opened on both sides of the outer wall of the protection tube 201, exhaust pipes 202 are respectively fixed to the two openings of the protection tube 201, turntables 203 are rotatably connected to the two ends of the protection tube 201, a plurality of air coolers 204 are fixed to one side of the turntable 203, a ventilation pipe 205 is fixed to the exhaust end of the air cooler 204, an exhaust end of the ventilation pipe 205 passes through one side of the turntable 203 and is fixed with an elbow 206, two groups of elbows 206 are both located inside the protection tube 201, a conveying mechanism 3 is fixed to the center of the top of the air cooling base 1, both sides of the cooling mechanism 2 are fixed to both sides of the inner wall of the conveying mechanism 3, and the two are connected, the cooling mechanism 2 also comprises two A fixing frame 207 is provided, and the bottoms of the two fixing frames 207 are respectively fixed to the tops of both ends of the air-cooling base 1, and the first motors 208 are respectively fixed to the opposite surfaces of the two fixing frames 207, and the first gear 209 is fixed to the output end of the first motor 208. A hole is provided at the center of one side of the turntable 203, and an inlet pipe 210 is fixed to the inner wall of the hole of the turntable 203, and a gear sleeve 211 is fixed to the outer wall of the turntable 203, and the teeth of the gear sleeve 211 are meshed with the teeth of the first gear 209. Notches are respectively provided on the other two sides of the protection tube 201, and a number of air coolers 204 are evenly distributed at equal angles around the center of the turntable 203. The air coolers 204, the ventilation pipe 205, the elbow 206, the protection pipe 201 and the exhaust pipe 202 are connected in sequence, and the air coolers 204, the first motor 208 and the second motor 302 are electrically connected in sequence, and the three share a control terminal.

[0023] It should be noted that: when cooling the plastic pipe, first put the plastic pipe into the device through the inlet pipe 210, then the conveying mechanism 3 starts to start, and at the same time the first motor 208 will also start, and the first gear 209 drives the gear sleeve 211 to rotate, and the turntable 203 will also rotate with it. At the same time, the air cooler 204 will also start, and convey cold air to the inside of the protective tube 201 through the ventilation pipe 205 and the bent pipe 206. At the same time, several bent pipes 206 will also rotate with the turntable 203 to cool the pipe. When the cold air at both ends of the protective tube 201 comes into contact with each other, it will be discharged through the exhaust pipe 202.

[0024] like Figure 4As shown, the utility model provides a technical solution: an air cooling device for plastic pipe production, including a conveying mechanism 3, the conveying mechanism 3 includes two shells 301, the notches of the two shells 301 are symmetrical, two second motors 302 are fixed to one side of the inner wall of the shell 301, and the output ends of the two second motors 302 are respectively fixed with crawler drive wheels 303, the teeth of the two crawler drive wheels 303 are meshed with a first crawler 304, the teeth of the inner wall of the first crawler 304 are meshed with a plurality of crawler driven wheels 305, and a plurality of fixing blocks 306 are respectively fixed on both sides of the first crawler 304, a spring rod 307 is fixed to the bottom of the fixing block 306, and an elastic strip 308 is fixed between one end of adjacent spring rods 307.

[0025] It should be noted that: when the plastic pipe is cooled, when the plastic pipe contacts one end of the conveying mechanism 3, the two sets of second motors 302 are started, which will cause the track drive wheel 303 to drive the two first tracks 304 to move. At this time, the two sets of elastic strips 308 will also move at a uniform speed under the movement of the two first tracks 304. When adjacent elastic strips 308 contact the plastic pipe, first, due to the action of the spring rod 307, the two adjacent elastic strips 308 will move away from each other. Because of the tightness of the elastic strips 308 themselves, they can be well connected with the pipe, thereby improving the stability of the pipe during cooling.
