Description

Technical Field

[0001] This utility model belongs to the field of film cooling technology, and in particular to a film cooling device. Background Technology

[0002] Hydraulic hoses consist of a liquid-resistant inner layer of synthetic rubber, a middle layer, multiple reinforcing layers, and a weather-resistant outer layer of synthetic rubber. The rubber sheet is an important intermediate product in the production of hydraulic hoses. After production, the rubber sheet needs to be cooled. Currently, most cooling methods use water cooling. However, most current cooling devices lack wiping components, resulting in a large amount of water adhering to the surface of the rubber sheet after water cooling. This water is difficult to remove quickly, thus affecting the efficiency of subsequent rubber sheet collection.

[0003] An existing Chinese patent (authorization announcement number CN206733451U) describes a film cooling device for detecting the cooling quality of film, which "includes a cooling pool and a detection mechanism located at one end of the film output cooling pool. The detection mechanism includes a guide roller located on the film travel path, a pressure plate arranged parallel to the guide roller, and baffles arranged at both ends of the pressure plate."

[0004] It is evident that the cited patent document suffers from the problem of difficulty in quickly removing the attached water. Utility Model Content

[0005] The purpose of this invention is to provide a film cooling device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a film cooling device, comprising a cooling box, with base plates installed on both inner walls of the cooling box, and threaded shafts rotatably connected to the top surfaces of the two base plates via pins, and movable plates with rubber scrapers threadedly fitted around the periphery of the two threaded shafts, a fan installed on one side of the cooling box, a blower hood connected to one side of the fan, a filter plate with a filter screen connected to the inner cavity of the blower hood via bolts, a connecting pipe connected to one side of the blower hood, an air inlet pipe connected to the free end of the connecting pipe, two hollow blocks symmetrically installed on one side of the cooling box, both ends of the air inlet pipe penetrating the cooling box and respectively connected to one side of the two hollow blocks, and several air outlets for blowing air connected to the opposite sides of the two hollow blocks.

[0007] Preferably, limit rods are installed on the top surfaces of both base plates, and both movable plates are slidably sleeved around the periphery of the two limit rods.

[0008] Preferably, a water tank for water cooling the film is installed on one side of the cooling box, and two first limiting rollers are symmetrically provided on the top surface of the water tank via a vertical plate.

[0009] Preferably, an electric push rod is mounted on one side of the water tank via a base plate, and the moving part of the electric push rod is connected to a lifting plate.

[0010] Preferably, the bottom surface of the lifting plate is symmetrically connected to two connecting blocks, and the bottom surfaces of the two connecting blocks are connected to a horizontal plate.

[0011] Preferably, both sides of the horizontal plate are rotatably connected by pins to two second limiting rollers for limiting the movement angle of the film.

[0012] Preferably, a water pump for adding cold water and a drain pump for discharging cold water are respectively installed on one side of the water tank.

[0013] Compared with the prior art, the technical effects and advantages of this utility model are as follows:

[0014] This film cooling device can move two movable plates by rotating two threaded shafts, which can scrape off a large amount of cold water adhering to the surface and bottom of the film. Compared with existing devices for cooling film, this device can clean the cold water adhering to the surface and bottom of the film, thus avoiding affecting the efficiency of subsequent film collection.

[0015] By turning on the fan, air can be blown onto the blower cover, allowing the air to be blown out from the air outlet, which speeds up the airflow around the rubber, accelerates the evaporation of moisture on the rubber surface, and also cools the rubber again.

[0016] The filter plate inside the blower shroud, installed with bolts, filters the air blown out by the blower, preventing the blower from blowing external dust onto the rubber sheet. It also makes it easy to disassemble and clean the filter plate. Attached Figure Description

[0025] In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention can be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described in order to avoid confusion with the present invention.

[0026] Unless otherwise defined, the directions mentioned herein, such as up, down, left, right, front, back, inside, and outside, are based on the directions shown in the figures of this utility model, and are explained here together.

[0027] The connection method can be any existing method, such as bonding, welding, or bolting, depending on the actual needs.

[0028] like Figures 1 to 5 The illustrated film cooling device includes a cooling box 1. The water-cooled film passes through the cooling box 1 and is connected to an external traction device. Base plates 2 are installed on both inner walls of the cooling box 1. Threaded shafts 3 are rotatably connected to the top surfaces of the two base plates 2 via pins. A handle is connected to the top of each threaded shaft 3 through the cooling box 1. Moving plates 4 with rubber scrapers are threaded onto the periphery of each threaded shaft 3. When the film passes through the cooling box 1, it is positioned between the two moving plates 4. Rotating the two handles rotates the two threaded shafts 3, causing the two moving plates 4 to move in opposite directions. This allows the rubber scrapers on opposite sides of the moving plates 4 to adhere to the surface and bottom of the film, removing the cold water adhering to the film surface and bottom. Since the two threaded shafts 3 drive the two moving plates 4, the two moving plates 4 can be adjusted according to the thickness of different films.

[0029] Limiting rods 21 are installed on the top surfaces of both base plates 2. Both movable plates 4 are slidably sleeved on the periphery of the two limiting rods 21. When the two movable plates 4 move longitudinally, they will move longitudinally on the periphery of the limiting rods 21, which can limit the movement trajectory of the two movable plates 4 and prevent them from rotating with the threaded shaft 3.

[0030] A fan 7 is installed on one side of the cooling box 1. A blower hood 8 is connected to the other side of the fan 7. A filter plate 11 with a filter screen is installed inside the blower hood 8 by bolts. A connecting pipe 9 is connected to one side of the blower hood 8. An air inlet pipe 10 is connected to the free end of the connecting pipe 9. Two hollow blocks 5 are symmetrically installed on one side of the cooling box 1. Both ends of the air inlet pipe 10 pass through the cooling box 1 and are connected to one side of the two hollow blocks 5 respectively. Several air outlets 6 for blowing air are connected to the opposite sides of the two hollow blocks 5. After the scraping is completed, the blower 7 is turned on so that the air blown by the blower 7 can be directed to the blower hood 8. The air then enters the connecting pipe 9 through the blower hood 8 and the air inlet pipe 10 through the connecting pipe 9. The air is then delivered to the two hollow blocks 5 through the air inlet pipe 10, and blown out from multiple air outlets 6. This blows the air onto the rubber sheet that has been scraped off by the moving plate 4, which speeds up the airflow around the rubber sheet and accelerates the evaporation of moisture on the rubber sheet surface. It also cools the rubber sheet again by blowing air, which can clean the cold water adhering to the rubber sheet surface and reduce the impact on the later collection efficiency of the rubber sheet.

[0031] The inner cavity of the blower hood 8 is connected to a filter plate 11 with a filter screen by bolts. The filter plate 11 can filter the air blown by the blower 7 towards the blower hood 8, preventing the blower 7 from blowing external dust onto the film and contaminating it. The filter plate 11 is connected to the blower hood 8 by bolts, making it convenient for personnel to disassemble and clean the filter plate 11.

[0032] A water tank 12 for water cooling the film is installed on one side of the cooling box 1. Two first limiting rollers 13 are symmetrically arranged on the top surface of the water tank 12 via a vertical plate. An electric push rod 14 is installed on one side of the water tank 12 via a base plate. The moving part of the electric push rod 14 is connected to a lifting plate 15. Two connecting blocks 16 are symmetrically connected to the bottom surface of the lifting plate 15. A horizontal plate 17 is connected to the bottom surface of the two connecting blocks 16. Two second limiting rollers 18 for limiting the movement angle of the film are rotatably connected to both sides of the horizontal plate 17 via pins. The operator passes the film over the first limiting roller 13 away from the cooling box 1, then into the water tank 12, passes it under the two second limiting rollers 18, and then passes it over the other first limiting roller 13 to enter the cooling box 1 and pass through it. The cold water in the water tank 12 cools the film. The two first limiting rollers 13 and the two second limiting rollers 18 can prolong the time the film spends in the water tank 12, thus prolonging the water cooling time.

[0033] Activating the electric push rod 14 will cause the lifting plate 15 to move longitudinally, which in turn causes the horizontal plate 17 to move longitudinally via the connecting block 16. This, in turn, causes the two second limit rollers 18 to move upward, allowing them to move above the water tank 12. This makes it easier for personnel to pass the film under the two second limit rollers 18. After passing the film, activating the electric push rod 14 again will cause the lifting plate 15, connecting block 16, and horizontal plate 17 to move the two second limit rollers 18 into the lower half of the water tank 12. This avoids the situation where personnel need to insert half of their body into the water tank 12 to pass the film under the two second limit rollers 18.

[0034] A water pump 19 for adding cold water and a drain pump 20 for discharging cold water are respectively installed on one side of the water tank 12. Both the water pump 19 and the drain pump 20 are connected to the water tank 12 by a delivery pipe, and both the water pump 19 and the drain pump 20 are connected to a water pipe. The water pipe connected to the water pump 19 is connected to a water supply device. By turning on the water pump 19, the cold water in the external water supply device can be delivered to the water pipe, and then delivered to the delivery pipe, and then delivered to the water tank 12 to cool the rubber inside the water tank 12. By turning on the drain pump 20, the cold water in the water tank 12 can be drawn into the delivery pipe, and then delivered to the water pipe for discharge, so that the cold water that has risen in temperature can be discharged and new cold water can be replaced.

[0035] Working principle:

[0036] The film cooling device guides the film over the first limiting roller 13 away from the cooling tank 1, then into the water tank 12, and over the two second limiting rollers 18, then over the other first limiting roller 13, thus entering and passing through the cooling tank 1. It then connects to an external traction device. At this point, a water pump 19 delivers cold water to the water tank 12 to cool the film. The external traction device then moves the film, allowing the cooled film to enter the cooling tank 1. Turning two levers drives two threaded shafts 3 to move two moving plates 4 longitudinally, allowing the two moving plates 4 to move together. The rubber scraper on one side can be applied to the surface and bottom of the rubber sheet to remove the cold water adhering to the surface and bottom of the rubber sheet. Then, the fan 7 is turned on, so that the air blown by the fan 7 enters the connecting pipe 9 through the blower hood 8, and then enters the air inlet pipe 10 through the connecting pipe 9. It can then be delivered to the two hollow blocks 5 through the air inlet pipe 10, and blown out from multiple air outlets 6. This blows the air onto the rubber sheet after it has been scraped by the moving plate 4, which can accelerate the air flow around the rubber sheet, accelerate the evaporation of moisture on the rubber sheet surface, and also cool the rubber sheet again by blowing air, thus cleaning the cold water adhering to the rubber sheet surface and reducing the impact on the later collection efficiency of the rubber sheet.
