Description

Technical Field

[0001] This utility model belongs to the field of drip irrigation tape production technology, specifically a cooling device for drip irrigation tape production. Background Technology

[0002] With the vigorous development of agriculture and the continuous waste of water resources, drip irrigation has become a more effective water-saving irrigation method in arid areas. As a result, the application of drip irrigation tape has gradually become widespread, and the demand is increasing. Currently, the manufacturing of drip irrigation tape mainly involves melting plastic and forming it into drip irrigation tape through an extrusion die. Due to the high temperature of the initially extruded drip irrigation tape, it needs to be cooled before subsequent processes such as perforation and winding can be carried out. The cooling rate of the drip irrigation tape should be moderate, neither too fast nor too slow. Too fast a cooling rate may cause cracks or stress concentration on the surface of the drip irrigation tape, while too slow a cooling rate may reduce production efficiency. Most existing cooling devices are air-cooled or water-cooled. Air-cooling has a fast cooling speed but uneven cooling, while water cooling is prone to contaminating the drip irrigation tape and causing blockage. At the same time, water cooling requires constant water changes, which reduces efficiency and increases costs. Therefore, it is necessary to design a device that can combine the advantages of air cooling and water cooling, so as to cool the drip irrigation tape evenly, improve product quality, avoid water pollution, and avoid the need for frequent water changes. Utility Model Content

[0003] To address the above technical problems, this utility model provides a device that combines the advantages of air cooling and water cooling, enabling uniform cooling of the drip irrigation tape, improving product quality, and preventing water pollution and frequent water changes. This solves the problems of traditional cooling devices having a single cooling method, low product quality, and being prone to water pollution and frequent water changes.

[0004] To solve the above technical problems, the technical solution of this utility model is as follows: a cooling device for drip irrigation tape production, including a cooling box and drip irrigation tape. The cooling box has several through holes on its side wall for the drip irrigation tape to pass through. The cooling box contains, from top to bottom, a spray box, a immersion box, and an air-cooling box. Traction roller groups are rotatably connected to each of the spray box, immersion box, and air-cooling box, through which the drip irrigation tape passes. An upper spray pipe and a lower spray pipe are fixedly connected to the spray box. The upper spray pipe and the lower spray pipe... Spray nozzles are fixedly connected to each pipe. Rotating rollers are rotatably connected inside the spray box and the air-cooled box. The rotating roller inside the spray box is located between the upper spray pipe and the lower spray pipe. A set of steering rollers is fixedly connected to both sides of the cooling box through a connecting frame. The drip irrigation tape is wound around the set of steering rollers. A water tank is fixedly connected inside the immersion tank. A pressure roller is rotatably connected inside the water tank, and a rotating shaft is rotatably connected to the upper side of both ends. The drip irrigation tape is in contact with the bottom of the pressure roller. A fan is fixedly connected to the side wall of the air-cooled box.

[0005] Furthermore, the traction roller assembly includes an upper traction roller and a lower traction roller. A first gear is fixedly connected to the upper traction roller, and a second gear is fixedly connected to the lower traction roller. A motor corresponding to the traction roller assembly is fixedly connected to the side wall of the cooling box, and a third gear is fixedly connected to the output end of the motor. The first gear, the second gear, and the third gear mesh and drive each other.

[0006] Furthermore, one end of both the upper water spray pipe and the lower water spray pipe is fixedly connected to a main water pipe through the side wall of the cooling box.

[0007] Furthermore, a water inlet pipe is fixedly connected to one side of the water tank. The water inlet pipe extends outward through the side wall of the water tank and the side wall of the cooling box. A water pump and a valve are fixedly connected to the water inlet pipe.

[0008] Furthermore, a first water outlet pipe is fixedly connected to the bottom of the spray box, penetrating the bottom wall of the spray box, and a second water outlet pipe is fixedly connected to the bottom of the immersion box, penetrating the bottom wall of the immersion box. Valves are installed on both the first and second water outlet pipes.

[0009] Furthermore, the cooling box has a door hinged to its front.

[0010] This utility model has the following advantages compared with the prior art:

[0011] 1. This utility model combines traditional air cooling and water cooling by dividing the cooling box into a spray box, a immersion box, and an air-cooling box. This allows for uniform cooling of the drip irrigation tape, increases the cooling speed, and improves product quality. By setting the sequence of spraying first and then immersion, pre-cooling can be performed during spraying, avoiding large temperature differences in the drip irrigation tape within a short period of time, which would affect product quality. By placing the water tank inside the immersion box, direct contact with outside air can be avoided. At the same time, the drip irrigation tape, after being pre-cooled by spraying, will not excessively pollute the water quality, ensuring that the drip irrigation tape is not contaminated after immersion. It also prevents the water in the tank from heating up too quickly, avoiding frequent water changes or cooling, which wastes resources and increases costs.

[0012] 2. By setting up traction roller sets and steering roller sets, the direction and power source of the drip irrigation tape can be guaranteed. Using traction roller sets to provide power will not damage the drip irrigation tape. The door hinged on the front of the cooling box can facilitate the cooling path guidance when the drip irrigation tape comes out. By setting up an air-cooling box, sufficient cooling time can be guaranteed to avoid the quality degradation of the drip irrigation tape due to excessively long or short cooling time.

[0017] The present invention will be further described below with reference to the accompanying drawings.

[0018] like Figures 1 to 3The cooling device shown includes a cooling box 1 and a drip irrigation tape 21. The cooling box 1 has several through holes on its side wall for the drip irrigation tape 21 to pass through. Three sets of through holes are symmetrically arranged to facilitate the passage of the drip irrigation tape 21. To combine air cooling and water cooling and improve product quality, a spray box 2, a water immersion box 3, and an air-cooling box 4 are arranged sequentially from top to bottom inside the cooling box 1. To enable the drip irrigation tape 21 to move along the cooling path, traction roller sets 8 are rotatably connected inside the spray box 2, water immersion box 3, and air-cooling box 4. The drip irrigation tape 21 passes through the traction roller sets 8. A set of traction rollers 8 is installed on the right side of the spray box 2, the left side of the immersion box 3, and the right side of the air-cooling box 4. To ensure uniform cooling of the drip irrigation tape, an upper spray pipe 5 and a lower spray pipe 6 are fixedly connected inside the spray box 2. Spray nozzles 9 are fixedly connected to both the upper and lower spray pipes 5 and 6. To support the drip irrigation tape 21 and ensure smoother movement of the drip irrigation tape 21 within the cooling box 1, rotating rollers 7 are rotatably connected inside the spray box 2 and the air-cooling box 4. The rotating roller 7 inside the spray box 2 is located between the upper spray pipe 5 and the lower spray pipe 6 to ensure the smooth movement of the drip irrigation tape 21. The flow sequence is as follows: first, the drip irrigation tape enters the spray tank 2 from the upper left side of the cooling tank 1; then, it enters the immersion tank 3 from the right side of the cooling tank 1; finally, it enters the air-cooled tank 4 from the lower left side of the cooling tank 1. A guide roller assembly 10 is fixedly connected to both sides of the cooling tank 1 via a connecting frame. The guide roller assembly 10 is divided into an upper guide roller assembly and a lower guide roller assembly. The drip irrigation tape 21 passes from the outside of the upper guide roller assembly, through the bottom of the lower guide roller assembly, and then enters the next stage. The guide roller assembly 10 is rotatably connected to the connecting frame, and the drip irrigation tape 21 is wound around the guide roller assembly 10. To ensure uniform cooling of the drip irrigation tape, it is fixed inside the immersion tank 3. A water tank 11 is connected, and treated pure water is introduced into the water tank 11. In order to ensure that the drip irrigation tape 21 is submerged in the water tank 11, a pressure roller 12 is rotatably connected in the water tank 11. In order to reduce the friction between the drip irrigation tape 21 and the side edge of the water tank 11 and protect the drip irrigation tape 21, a rotating shaft is rotatably connected to the upper side of both ends of the water tank 11. The drip irrigation tape 21 contacts the bottom of the pressure roller 12 and contacts the rotating shaft. In order to cool down again and drain the water remaining on the drip irrigation tape 21, two identical fans 15 are fixedly connected to the side wall of the air-cooled box 4.

[0019] To provide power to the drip irrigation tape 21, the traction roller group 8 includes an upper traction roller 81 and a lower traction roller 82. A first gear 20 is fixedly connected to the upper traction roller 81, and a second gear 19 is fixedly connected to the lower traction roller 82. A motor 18 corresponding to the traction roller group 8 is fixedly connected to the side wall of the cooling box 1. A third gear 22 is fixedly connected to the output end of the motor 18. In order to ensure that the upper traction roller 81 and the lower traction roller 82 rotate in opposite directions, the first gear 20, the second gear 19, and the third gear 22 are meshed and driven together.

[0020] In order to spray water at the same time, a main water pipe is fixedly connected to one end of the upper water pipe 5 and the lower water pipe 6 through the side wall of the cooling box 1. To ensure that the drip irrigation tape 21 is not contaminated, treated pure water is introduced into the main water pipe.

[0021] To ensure that the water in the water tank 11 is clean and not contaminated, a water inlet pipe 13 is fixedly connected to one side of the water tank 11. The water inlet pipe 13 extends outward through the side wall of the water tank 11 and the side wall of the cooling box 1. A water pump 14 is fixedly connected to the water inlet pipe 13 and a valve is installed on it.

[0022] In order to avoid water waste and enable water recycling, a first water outlet pipe 17 is fixedly connected to the bottom of the spray box 2, penetrating the bottom wall of the spray box 2. The other end of the first water outlet pipe 17 extends out of the cooling box 1. A second water outlet pipe 16 is fixedly connected to the bottom of the immersion box 3, penetrating the bottom wall of the immersion box 3. The other end of the second water outlet pipe 16 extends out of the cooling box 1. Valves are installed on both the first water outlet pipe 17 and the second water outlet pipe 16.

[0023] To facilitate guiding the drip irrigation tape 21 head into the correct cooling path at the beginning, a door is hinged to the front of the cooling box 1.

[0024] The specific working process of this utility model is as follows:

[0025] When cooling of the drip irrigation tape 21 is required, first open the box door and place the drip irrigation tape 21 on the rotating roller 7 through the through hole on the left side of the spray box 2. At this time, turn on the main water pipe and start spraying water in the spray box 2 to cool and harden the drip irrigation tape 21. Then, pass the drip irrigation tape through the traction roller group 8 and the steering roller group 10 in sequence, and enter the water tank 11. Insert the drip irrigation tape 21 under the pressure roller 12, and then through the steering roller group 10 into the air-cooling box 4. After completing the above sequence, close the box door. Then, turn on the motor 18 to start rotating all the traction roller groups 8 and turn on the main water pipe. The drip irrigation tape 21 is first cooled by being sprayed with purified water in the spray box 2, and then enters the water tank 11 for further cooling. At the same time, the fan 15 is turned on to air-cool the drip irrigation tape 21, while the residual water on the drip irrigation tape 21 is drained. The water in the spray box 2 is recycled from the first outlet pipe 17 below. When the water in the water tank 11 is not pure enough or the temperature is too high, the valve on the second outlet pipe 16 is opened, and purified water is introduced into the inlet pipe 13 to replace the water, avoiding frequent water changes. Cooling according to the above steps can make the drip irrigation tape 21 cool evenly, improve product quality, and avoid water contamination and frequent water changes that waste resources.
