Description

Technical Field

[0001] This utility model relates to the field of protective film production, and in particular to a cooling mechanism for the production of modified masterbatch for polyethylene protective film. Background Technology

[0002] Polyethylene protective film is widely used for surface protection of various products, especially in the electronics, home appliance, and construction industries. As a protective film, it can effectively prevent damage to the product surface from the external environment.

[0003] Cooling is crucial in the production of polyethylene protective film. Traditional cooling methods mostly rely on conventional cooling water or gas spraying. When using coolant, the flow of coolant is uneven, making it impossible to effectively achieve comprehensive and uniform cooling of the protective film surface. Moreover, most existing cooling equipment cannot achieve coolant recycling, resulting in a large amount of coolant waste. Although some equipment does recycle coolant, it does not cool the coolant after use, affecting the subsequent cooling effect. Utility Model Content

[0004] This utility model provides a cooling mechanism for the production of modified masterbatch for polyethylene protective film. When cooling the protective film, the coolant can cover the surface of the protective film to improve the cooling effect. When using the cooling device, the coolant after use can be used for cooling multiple times to further improve the cooling effect of the protective film.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a cooling mechanism for the production of polyethylene protective film modified masterbatch, the mechanism comprising:

[0006] Processing box;

[0007] A connecting box is fixedly installed on one side of the processing box, and the two sides of the inner wall of the connecting box are provided with bidirectional threaded rods through bearings;

[0008] Two sleeves are threaded onto the outer surface of the bidirectional threaded rod, and a connecting rod is fixedly provided on the outer surface of each sleeve;

[0009] A flow guide plate is provided on one side of the processing box;

[0010] A liquid storage tank is fixedly installed on one side of the guide plate, and a first connecting pipe is installed on one side of the liquid storage tank;

[0011] A delivery pump is installed at one end of the first connecting pipe, and a Y-shaped pipe is installed at the output end of the first connecting pipe.

[0012] As a further improvement of this utility model: both ends of the Y-shaped tube are equipped with second connecting tubes, and one end of each of the two second connecting tubes is equipped with a flexible tube.

[0013] As a further improvement of this utility model: a liquid outlet pipe is fixedly provided on one side of each of the two hoses, and multiple nozzles are installed on the outer surface of each of the two liquid outlet pipes. One end of each of the two connecting rods is fixedly provided on the outer surface of the two liquid outlet pipes, and the two connecting rods are slidably provided on one side of the connecting box.

[0014] As a further improvement of this utility model: a partition is fixedly provided on the inner wall of the processing box.

[0015] As a further improvement of this utility model: a bidirectional motor is installed on one side of the connecting box, and the output shaft of the bidirectional motor is fixedly set at one end of the bidirectional threaded rod.

[0019] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0020] In this invention, when cooling the polyethylene protective film, the protective film to be cooled is placed on a partition. Coolant and ice are then poured into the storage tank. The external power switch of the delivery pump is turned on, generating suction at the pump's input. The coolant from the storage tank is then discharged through the first connecting pipe onto the Y-shaped pipe under the pump's action. From there, it is delivered through the Y-shaped opening of the Y-shaped pipe to the second connecting pipe, and further through two flexible hoses to two outlet pipes. Finally, it is sprayed through multiple nozzles into the processing tank and onto the protective film on the partition. The cooling process involves the coolant covering the surface of the protective film to enhance cooling efficiency. During cooling, the coolant inside the treatment tank flows through multiple small holes in the partition to the inside of the guide plate. The transmission rod drives the rotating rod to rotate, further agitating the coolant inside the storage tank with multiple stirring plates. This ensures that the coolant and the ice blocks inside the storage tank come into full contact, cooling the coolant for reuse. Thus, the coolant can be used multiple times after use, further improving the cooling effect on the protective film. Attached Figure Description

[0026] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0027] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0028] Example 1, as Figures 1-4 As shown, this utility model provides a cooling mechanism for the production of modified polyethylene protective film masterbatch. The mechanism includes a processing box 1; a connecting box 202, fixedly disposed on one side of the processing box 1, with bidirectional threaded rods 203 mounted on both sides of the inner wall of the connecting box 202 via bearings; two sleeves 204, threaded onto the outer surfaces of the bidirectional threaded rods 203 respectively, with connecting rods 213 fixedly disposed on the outer surfaces of both sleeves 204; a guide plate 2, disposed on one side of the processing box 1; a liquid storage tank 3, fixedly disposed on one side of the guide plate 2, with a first connecting pipe 206 installed on one side of the liquid storage tank 3; and a delivery pump 207, installed at one end of the first connecting pipe 206. A Y-shaped tube 208 is installed on the output end of 6. A second connecting tube 209 is installed on both ends of the Y-shaped tube 208. A hose 210 is installed on one end of each of the two second connecting tubes 209. An outlet pipe 211 is fixedly installed on one side of each of the two hoses 210. Multiple nozzles 212 are installed on the outer surface of each of the two outlet pipes 211. One end of each of the two connecting rods 213 is fixedly installed on the outer surface of the two outlet pipes 211. The two connecting rods 213 are slidably installed on one side of the connecting box 202. A partition 201 is fixedly installed on the inner wall of the treatment box 1. A bidirectional motor 205 is installed on one side of the connecting box 202. The output shaft of the bidirectional motor 205 is fixedly installed on one end of the bidirectional threaded rod 203.

[0029] By adopting the above technical solution, the protective film that needs to be cooled is placed on the partition 201. At this time, coolant and ice are poured into the storage tank 3, and the external power switch of the delivery pump 207 is turned on. The input end of the delivery pump 207 generates suction, which discharges the coolant inside the storage tank 3 through the first connecting pipe 206 to the Y-shaped pipe 208 under the action of the delivery pump 207. Then, it is delivered to the second connecting pipe 209 through the Y-shaped port of the Y-shaped pipe 208, and further discharged into the two outlet pipes 211 through the two hoses 210. It is then sprayed into the processing tank 1 through multiple nozzles 212, and further sprayed onto the protective film on the partition 201 to cool it. When spraying coolant, the external power switch of the bidirectional motor 205 is turned on. The power switch activates the output shaft of the bidirectional motor 205, which in turn drives the bidirectional threaded rod 203 to rotate. The output shaft of the bidirectional motor 205 can rotate in both directions. The outer surface of the bidirectional threaded rod 203 has two threaded grooves with different directions of rotation. Two sleeves 204 are connected to the two threaded grooves with different directions of rotation, and the two connecting rods 213 can slide on one side of the connecting box 202. Thus, when the bidirectional threaded rod 203 rotates in different directions, the two sleeves 204 move in opposite or relative directions on the outer surface of the bidirectional threaded rod 203. By controlling the direction of rotation of the output shaft of the bidirectional motor 205, the two sleeves 204 drive the two liquid outlet pipes 211 to move back and forth through the two connecting rods 213, so that the surface of the protective film can be sprayed with coolant.

[0030] Example 2, as Figures 1-4 As shown, rotating rods 301 are installed on both sides of the inner wall of the liquid storage tank 3 via bearings. Multiple stirring plates 302 are fixedly installed on the outer surface of the rotating rods 301. A transmission rod 303 is fixedly installed at one end of the rotating rods 301. A first pulley 304 is fixedly sleeved on the outer surface of the transmission rod 303. A belt 305 is installed on the outer surface of the first pulley 304. A second pulley 306 is installed on the inner wall of the belt 305. The second pulley 306 is fixedly sleeved on the outer surface of the bidirectional threaded rod 203.

[0031] By adopting the above technical solution, the coolant inside the treatment tank 1 flows through multiple small holes on the partition 201 into the interior of the guide plate 2. The coolant then flows through the inclined surface inside the guide plate 2 into the interior of the storage tank 3. When the bidirectional threaded rod 203 rotates, it drives the second pulley 306 to rotate, which in turn drives the first pulley 304 to rotate via the belt 305. When the first pulley 304 rotates, it drives the rotating rod 301 to rotate via the transmission rod 303, which further causes multiple stirring plates 302 to stir the coolant inside the storage tank 3, so that the coolant and the ice blocks inside the storage tank 3 come into full contact, cooling the coolant for reuse.

[0032] Working principle: When cooling the polyethylene protective film, the protective film to be cooled is placed on the partition 201. At this time, coolant and ice are poured into the storage tank 3. The external power switch of the delivery pump 207 is turned on, and the input end of the delivery pump 207 generates suction, which discharges the coolant in the storage tank 3 through the first connecting pipe 206 to the Y-shaped pipe 208 under the action of the delivery pump 207. Then, it is delivered through the Y-shaped port of the Y-shaped pipe 208 to the second connecting pipe 209, and further discharged through two hoses 210 into two outlet pipes 211, and sprayed through multiple nozzles 212. The coolant is sprayed into the interior of the treatment tank 1 and further sprayed onto the protective film on the partition 201 for cooling. During the spraying of coolant, the external power switch of the bidirectional motor 205 is turned on, causing the output shaft of the bidirectional motor 205 to drive the bidirectional threaded rod 203 to rotate. The output shaft of the bidirectional motor 205 can rotate in both directions. The outer surface of the bidirectional threaded rod 203 has two threaded grooves with different helix directions. Two sleeves 204 are connected to the two threaded grooves with different helix directions, and the two connecting rods 213 can slide on one side of the connecting box 202. This allows the bidirectional threaded rod 203 to rotate without... In the same direction, the two sleeves 204 move in opposite or opposite directions on the outer surface of the bidirectional threaded rod 203. By controlling the direction of rotation of the output shaft of the bidirectional motor 205, the two sleeves 204 drive the two liquid outlet pipes 211 to move back and forth through the two connecting rods 213, so that coolant can be sprayed onto the surface of the protective film. Thus, when cooling the protective film, the coolant can cover the surface of the protective film, improving the cooling effect. During cooling, the coolant inside the treatment tank 1 flows into the interior of the guide plate 2 through multiple small holes on the partition 201. The coolant flows into the interior of the guide plate 2 through the inclined surface inside the guide plate 2. Inside the storage tank 3, when the bidirectional threaded rod 203 rotates, it drives the second pulley 306 to rotate, which in turn drives the first pulley 304 to rotate via the belt 305. When the first pulley 304 rotates, it drives the rotating rod 301 to rotate via the transmission rod 303, which in turn causes multiple stirring plates 302 to stir the coolant inside the storage tank 3, so that the coolant and the ice blocks inside the storage tank 3 come into full contact, cooling the coolant and allowing it to be reused. Thus, when using the cooling device, the coolant can be used for cooling multiple times, further improving the cooling effect of the protective film.
