Description

Technical Field

[0001] This utility model relates to the field of PS film stretching and cooling technology, and more specifically to a PS film stretching and cooling device. Background Technology

[0002] PS film stretching typically involves heating polystyrene to a certain temperature to soften it and make it easier to deform. Then, it is stretched mechanically and then cooled and shaped by a cooling device to improve the film's barrier properties, stiffness, flatness, tensile strength, and porosity.

[0003] As shown in the prior art published in CN222346087U, although this prior art uses a rotary motor to drive the PS film for conveying and processing, and the PS film after production can be rapidly cooled by a cooling hood of a cooling assembly, with cold air from a refrigeration unit being delivered to the cooling hood through a conveying pipe and released onto the PS film through nozzles for cooling, the position of the cold air in this prior art is fixed. This means that the technical solution cannot adjust the coverage area of ​​the cold air according to the specifications of the film, nor can it adjust the cold air rate in a timely manner as needed. Adjusting the cold air rate using cold air control equipment requires a certain amount of waiting time, which affects the cooling effect of the film. Utility Model Content

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Refer to the instruction manual appendix Figure 1-7 This utility model provides a PS film stretching and cooling device, including a cooling component for cooling the PS film disposed inside a mounting bracket 1; the cooling component includes a fixed housing 6 and a movable housing 7 disposed at the bottom of a movable base 3, the fixed housing 6 being disposed at the rear side of the movable housing 7, and nozzles 21 being installed at the bottom of both the fixed housing 6 and the movable housing 7, the top of the fixed housing 6 being fixedly attached to the bottom of the movable base 3; a plurality of inner tubes 8 are fixedly connected to the side of the fixed housing 6 near the movable housing 7, and an outer tube 9 for connecting the movable housing 7 is sleeved on the outside of the inner tubes 8; a plurality of assembly tubes 10 are fixedly connected to the side of the movable housing 7 away from the fixed housing 6, and a connecting post 11 is installed on the movable housing 7, the top end of the connecting post 11 penetrating the assembly hole 5 and extending to the top of the movable base 3; a cooling unit 12 is disposed at the top of the fixed housing 6, the cooling unit 12 is installed at the top rear end of the mounting bracket 1, and the output end of the cooling unit 12 is connected to a connecting hose 13 for connecting to the fixed housing 6.

[0032] In use, the staff starts the refrigeration unit 12 through the background control system. The refrigeration unit 12 delivers cold air to the connected fixed casing 6 and movable casing 7 through the connecting hose 13. The air is then sprayed out through the nozzle 21 to cool and shape the PS film. At the same time, in order to increase the cooling range, the movable casing 7 is connected to the outside of the inner tube 8 inserted into the fixed casing 6 through the outer tube 9, thereby connecting the movable casing 7 and the fixed casing 6 to expand the cooling range. At the same time, the movable casing 7 can also be equipped with other movable casings 7 through the mounting pipe 10, so as to adjust the cooling range according to the cooling needs.

[0033] To ensure the stability of the movable chassis 7 after installation, it is necessary to limit its movement and also ensure that it can move up and down with the movable base 3. Figure 3 and 5 As shown, each set of positioning components includes a positioning ring 14, which is installed on the top of the movable seat 3. The positioning ring 14 has multiple spaced positioning holes 15 on its exterior, and each positioning hole 15 has a positioning bolt 16 inside. The connecting post 11 is located inside the positioning ring 14, and the positioning bolt 16 extends into the connecting post 11. The positioning bolt 16 is threadedly connected to the connecting post 11.

[0034] In use, the operator lifts the movable housing 7, causing the connecting column 11 on the movable housing 7 to move into the assembly hole 5. Then, the movable housing 7 is moved backward, so that the outer tube 9 on the movable housing 7 is nested outside the inner tube 8 on the fixed housing 6, and the connecting column 11 is inserted into the positioning ring 14. Subsequently, the connecting column 11 is fixed by multiple positioning bolts 16 to prevent the movable housing 7 from becoming loose. At the same time, the movable housing 7 can also move up and down with the moving seat 3, so as to achieve the effect of adjusting the height of the movable housing 7.

[0035] The mounting bracket 1 is equipped with an adjusting component for adjusting the height of the refrigeration component. The adjusting component includes two spaced electric push rods 2. The top of the electric push rods 2 is fixed to the top of the inner cavity of the mounting bracket 1. The bottom of the two electric push rods 2 is provided with the same movable seat 3, and the bottom of the electric push rods 2 is equipped with a connecting bracket 4 for connecting the movable seat 3. The movable seat 3 is provided with an assembly hole 5 on the outside, and multiple sets of positioning components for fixing the refrigeration component are provided outside the assembly hole 5.

[0036] In use, the staff operates the back-end control system to start the electric push rod 2. The electric push rod 2 drives the moving seat 3 to move through the connecting bracket 4. The moving seat 3 then drives the cooling component to move up and down simultaneously, thereby adjusting the height of the cooling component. If the cooling component is too close, the cooling speed will be faster, causing the PS film surface to shrink rapidly and making it prone to defects such as bubbles. If the cooling component is too close, the cooling efficiency will be low, and the PS film cannot be quickly and effectively shaped. Therefore, by adjusting the height of the cold air, the angle and coverage of the cold air jet can be adjusted, and a suitable cooling speed can be found to ensure that the PS film can be quickly and stably shaped after stretching. This can adapt to the cooling and shaping requirements of PS films of different specifications without replacing the entire cooling component or making large-scale equipment adjustments, thus improving the practicality and flexibility of this utility model.

[0037] After the above structure is assembled and adjusted, a PS film needs to be installed for stretching, cooling, and orientation. Figure 1 and 2As shown, the bottom end of the mounting bracket 1 is provided with an active roller 17 and a driven roller 18. The active roller 17 is located behind the driven roller 18, and both ends of the active roller 17 and the driven roller 18 are movably connected to the inner wall of the mounting bracket 1 through rotating shafts. A servo motor 19 is installed on one side of the rear end of the mounting bracket 1, and the output shaft of the servo motor 19 passes through the mounting bracket 1 and is fixed together with the rotating shaft on the active roller 17. Observation windows 20 are embedded on both sides of the mounting bracket 1.

[0038] In use, the operator places the PS film around the active roller 17 and the driven roller 18, and drives the active roller 17 to rotate by the servo motor 19. This allows the PS film to run under the cooling unit, achieving the effect of cooling and shaping the PS film. At the same time, the cooling and shaping effect of the PS film can be observed through the observation window 20.

[0039] When cooling the PS film, it is necessary to avoid impurities adhering to the PS film, such as... Figure 1 , 6 As shown in Figure 7, the mounting bracket has a top box 22 and a bottom box 23 on its front side. Multiple air pipes 24 are installed on the side of the top box 22 and the bottom box 23 that are close to each other. Support plates 25 for connecting the mounting bracket are installed on both sides of the top box 22 and the bottom box 23. Multiple connecting pipes 26 for connecting the bottom box 23 are fixedly connected to the top of both ends of the top box 22. The bottom of the bottom box 23 has a sealing shell 27. The bottom of the bottom box 23 is fixedly connected to a bottom pipe 28 for connecting the sealing shell 27. The sealing shell 27 has a filter box 29 inside. A sealing plate 30 is installed on one end of the filter box 29. The sealing plate 30 is located outside one end of the sealing shell 27. An air outlet pipe 31 is fixedly connected to the end of the sealing shell 27 away from the sealing plate 30. A fan 32 is installed inside the air outlet pipe 31.

[0040] In use, the connecting pipe 26 connects the top box 22 and the bottom box 23 into one unit. Then, through the air pipes 24 on the top box 22 and the bottom box 23, when the fan 32 is running, the impurities adhering to the PS membrane can be drawn into the top box 22 and the bottom box 23 through the air pipes 24. The impurities in the top box 22 are transported to the bottom box 23 through the connecting pipe 26. The impurities concentrated in the bottom box 23 are then transported to the filter box 29 in the encapsulation shell 27 through the bottom pipe 28. At the same time, the filter box 29 collects the impurities in a concentrated manner, preventing the impurities from escaping and polluting the working environment. Finally, the operator pulls the sealing plate 30 to pull the filter box 29 out of the encapsulation shell 27, which facilitates the centralized treatment of the impurities in the filter box 29 and improves the convenience of the operator in handling impurities.

[0041] Finally: The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
