Description

Technical Field

[0001] This utility model relates to the field of plastic film processing, specifically to a cooling structure for a blown film machine. Background Technology

[0002] As a key piece of equipment in plastic film production, the performance of the cooling system in a blown film machine directly affects the molding quality and production efficiency of the plastic film. Cooling via convection in a cold air environment is relatively expensive. Water cooling is cheaper, but the open tank design can easily lead to a continuous rise in water temperature. When the cooling water temperature exceeds 30℃, the cooling effect on materials such as polyethylene decreases, making real-time monitoring of the water temperature essential.

[0003] In addition, it is necessary to consider how to filter water and remove moisture after water cooling, and how to achieve low-cost cooling while ensuring the quality of film cooling. This is of great significance for promoting the development of blown film technology towards green manufacturing. Utility Model Content

[0004] The technical problems to be solved by this invention are water temperature control and monitoring in water cooling systems, and drying after water cooling.

[0005] To solve the above problems, the technical solution adopted by this utility model is as follows: This utility model is a cooling structure for a blown film machine, including a base and a water tank. The water tank is fixedly mounted on the base. The inner wall of the water tank has an arc-shaped structure. A rotating roller is rotatably mounted inside the water tank. Two sets of obstructions are symmetrically mounted on the water tank. A detection structure is provided on the water tank. A drying structure is provided on the water tank. The obstruction structure includes a sliding frame, an outer frame, a screen plate, and an mounting strip. The sliding frame is symmetrically fixedly mounted on the inner wall of the water tank. The outer frame slides on the two sliding frames. The screen plate is fixedly mounted on the outer frame. A rotating opening is provided on the screen plate. The rotating roller rotates through the rotating opening. The mounting strip is fixedly mounted on the outer frame and is mounted on the water tank.

[0006] Furthermore, the water tank is equipped with a feed guide roller.

[0007] Furthermore, the detection structure includes a fixing frame, connecting strips, and locking rings. The fixing frame is installed on the water tank, the connecting strips are fixed on the fixing frame, and there are multiple sets of connecting strips and multiple sets of locking rings. Each locking ring is fixed on one set of connecting strips.

[0008] Furthermore, an anti-slip pad is bonded inside the engagement ring.

[0009] Furthermore, the mounting bracket is equipped with an indicator light.

[0010] Furthermore, the drying structure includes a support frame, a first set of filter rollers and a second set of filter rollers. Two sets of support frames are symmetrically arranged. The support frames are installed on the water tank.

[0011] Furthermore, the support frame is equipped with multiple sets of support bars, and multiple sets of small-power fans are installed on the support bars. Multiple sets of small fans are placed on the base and located below the small-power fans.

[0012] The beneficial effects of this utility model by adopting the above structure are as follows:

[0013] 1. Water cooling is used for temperature reduction, and a detection structure is included. If the water temperature can no longer meet the requirements, it needs to be replaced in time, or a chiller can be used to circulate cold water to maintain the water temperature. Water cooling is relatively inexpensive and effective.

[0014] 2. The drying structure filters out water, and the fan can be turned on to dry the passing products when needed, so that the products will not be too damp after being cooled by water. Attached Figure Description

[0021] As per the instruction manual Figures 1-3As shown, this utility model is a cooling structure for a blown film machine, including a base 1 and a water tank 2. The water tank 2 is fixedly mounted on the base 1. The inner wall of the water tank 2 has an arc-shaped structure. A rotating roller 3 is rotatably mounted inside the water tank 2. The temperature of the poured-in cold water is controlled between 10-25℃. The temperature may vary depending on the material (polyethylene, polypropylene, etc.) and is adjusted according to actual production conditions. The water level is slightly higher than the lowest point of the rotating roller 3. Two sets of baffles 4 are symmetrically mounted on the water tank 2. A detection structure 5 and a drying structure 6 are also provided on the water tank 2. The baffle structure includes a sliding frame 7, an outer frame 8, a mesh plate 9, and an mounting strip 10. The sliding frame 7 is symmetrically fixedly mounted on the inner wall of the water tank 2. The outer frame 8 slides on the two sliding frames 7. The mesh plate 9 is fixedly mounted on the outer frame 8 and has a rotating opening. The rotating roller 3 rotates through the rotating opening. The mounting strip 10 is fixedly mounted on the outer frame 8 and is mounted on the water tank 2. A feed guide roller is provided on the water tank 2.

[0022] As per the instruction manual Figure 4 As shown, the detection structure 5 includes a fixing frame 12, connecting strips 13, and locking rings 14. The fixing frame 12 is installed on the water tank 2, and the connecting strips 13 are fixedly mounted on the fixing frame 12. Multiple sets of connecting strips 13 and multiple sets of locking rings 14 are provided, each locking ring 14 being fixedly mounted on one set of connecting strips 13. Anti-slip pads 15 are adhered inside the locking rings 14. A thermometer is inserted into the locking rings 14 to measure the water temperature in the water tank 2, providing real-time monitoring. If the water temperature exceeds the set value, new cold water needs to be added. An indicator light 16 is provided on the fixing frame 12, which can be turned on during operation as a working indicator light or a hazard indicator light, and can be controlled from the control room or by an interruption.

[0023] As per the instruction manual Figure 5 As shown, the drying structure 6 includes a support frame 17, a first set of filter rollers 18, and a second set of filter rollers 19. The support frame 17 is symmetrically arranged in two sets and is mounted on the water tank 2. The first set of filter rollers 18 is mounted on the two sets of support frames 17, and the second set of filter rollers 19 is mounted on the two sets of support frames 17. The roller set contains two sets of rollers for filtering water. It is recommended that the second set of filter rollers 19 be slightly higher than the first set of filter rollers 18. The second set of filter rollers 18 can use sponge rollers.

[0024] As per the instruction manual Figure 5 As shown, the support frame 17 is equipped with multiple sets of support bars 20, and multiple sets of small power fans 21 are installed on the support bars 20. Multiple sets of small fans (not shown in the figure) are placed on the base 1 and located below the small power fans 21. It is not recommended that the power of the small power fans 21 and the small fans be too large, below 20W.

[0025] In practical use: the plastic film is wrapped around the feed guide roller and passes through the rotating roller 3 from the bottom. Then it passes through the first filter roller group 18 and the second filter roller group 19. Cooling water is added to the water tank 2. The water temperature is recommended to be between 10℃ and 25℃. It can be adjusted flexibly according to the actual material and production situation. A thermometer is inserted into the locking ring 14 to detect the water temperature. The plastic film is cooled down by passing through the water tank 2 in sequence. If necessary, a small fan and a low-power fan 21 can be turned on to blow air and dehumidify the plastic film.
