Description

Technical Field

[0001] This utility model relates to the field of PET film production technology, and more specifically, to a high-efficiency circulating drying box for PET film production. Background Technology

[0002] PET film, short for polyethylene terephthalate film, is a high-performance plastic film.

[0003] During the processing of PET film, the PET film undergoes a water bath process to wash away impurities or dust. After the water bath, it is wiped dry with top and bottom cloths. However, during the wiping process, it is often impossible to wipe it completely dry, resulting in the PET film remaining damp on the surface during subsequent production. Therefore, it is necessary to dry the surface.

[0004] In a typical drying oven, one end of the PET film is first placed inside. To prevent wrinkles during drying, the film is passed through one side of the oven and through the middle of the limiting assembly. Then, the circulating dryer is activated to dry both sides of the PET film. Once one end is dry, it is removed from the other side of the oven and fixed to the film roll. The rotation of the film roll then moves the PET film, causing it to be wound around the top of the roll. However, the limiting assembly consists of a spring, a compression block, and a limiting wheel. Although the spring applies a downward force, it deforms when a force is applied in the opposite direction, causing it to move upward. This results in an inability to provide a stable limit for the PET film, necessitating modification and optimization. Utility Model Content

[0005] In order to overcome the shortcomings of the prior art, this utility model provides a high-efficiency circulating drying box for PET film production, which has the advantages of stable positioning and easy fixation.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a high-efficiency circulating drying box for PET film production, comprising a base and a box body, wherein the box body is fixedly disposed above the base;

[0007] A bracket is fixedly installed on the top of the box. Connecting rods are rotatably installed on both the left and right sides of the bracket. One end of the connecting rod passes through one side of the bracket and a disc is fixedly installed on one end of the connecting rod. A protrusion is fixedly installed on one side of the disc. A sleeve is movably fitted onto the outer surface of the protrusion. A movable rod is fixedly installed at the bottom of the sleeve. The bottom of the movable rod extends into the interior of the box and is fixedly installed with a movable frame. A first limiting wheel is rotatably installed on the inner side of the movable frame. A drive mechanism is fixedly installed on the top of the bracket. Second limiting wheels are fixedly installed on both sides inside the box. The movable rod is movably connected to the box.

[0008] As a preferred embodiment of this utility model, a rotating mechanism is fixedly installed on one side of the housing, a circular plate is fixedly installed at one end of the rotating mechanism, a rotating roller is fixedly installed on one side of the circular plate, a limiting plate is fixedly installed at one end of the rotating roller, a threaded rod is rotatably installed on one side of the limiting plate, one end of the threaded rod passes through the upper and lower sides of the limiting plate, a knob is fixedly sleeved on the outer surface of the threaded rod, a threaded sleeve is threadedly sleeved on the outer surface of the threaded rod, a friction plate is fixedly installed at one end of the threaded sleeve, and one end of the friction plate extends into the interior of the circular plate and is movably connected to the circular plate.

[0009] As a preferred technical solution of this utility model, the rotating mechanism includes a base plate fixedly disposed on one side of the box body, a motor fixedly installed on the top of the base plate, a side frame fixedly installed on one side of the box body, and one end of the drive shaft of the motor passing through the left and right sides of the side frame and fixedly connected to the circular plate.

[0010] As a preferred embodiment of this utility model, the driving mechanism includes a self-locking motor fixedly mounted above the bracket. One end of each of the two drive shafts of the self-locking motor is fixedly mounted with a rotating frame, and one end of the rotating frame is fixedly connected to a connecting rod.

[0011] As a preferred embodiment of this utility model, a guide roller is fixedly installed on one side of the box, and a heat dissipation vent is provided on one side of the box.

[0012] As a preferred technical solution of this utility model, a bottom support is fixedly installed on the bottom of the inner side of the box, and a circulating dryer is fixedly installed on the top of the bottom support. There are two circulating dryers, and the other circulating dryer is located at the top of the inner side of the box and is fixedly connected to the top of the inner side of the box.

[0013] As a preferred embodiment of this utility model, a side door is hinged to one side of the box body, a glass plate is fixedly installed on one side of the side door, and a controller is fixedly installed on one side of the box body. The controller is electrically connected to the self-locking motor, the motor, and the circulating dryer.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] 1. This utility model uses a controller to start a self-locking motor, which drives the rotating frame to rotate, thereby driving the rotation of the disc and the protrusion, which in turn drives the moving rod to move, thus moving the first limiting wheel to limit the PET film. Compared with traditional devices, this device uses the cooperation of the disc and the protrusion to move the first limiting wheel. Compared with traditional devices that use a spring assembly to limit the PET film, the spring is prone to deformation when subjected to force, resulting in unstable limiting of the PET film. This device, with the cooperation of the disc and the protrusion to drive the movement of the first limiting wheel, makes the limiting wheel more stable in limiting the PET film, while improving the convenience of operation and thus improving the working efficiency of the device.

[0016] 2. This utility model uses a knob to rotate a threaded rod, which in turn moves a threaded sleeve. The movement of the threaded sleeve then moves a friction plate. Compared to traditional devices, this device uses a friction plate to hold the inner side of the film cylinder in place, preventing slippage between the film cylinder and the rotating roller during rotation. This prevents the film cylinder from not rotating and thus ensuring the PET film is properly wound onto it. The friction between the friction plate and the film cylinder ensures that the rotation of the rotating roller stably drives the rotation of the friction plate, thereby improving the device's working efficiency.

[0024] 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.

[0025] like Figures 1 to 6 As shown, this utility model provides a high-efficiency circulating drying box for PET film production, including a base 1 and a box body 2, with the box body 2 fixedly disposed above the base 1;

[0026] A bracket 10 is fixedly installed on the top of the housing 2. Connecting rods 13 are rotatably installed on both the left and right sides of the bracket 10. One end of the connecting rod 13 passes through one side of the bracket 10. A disc 14 is fixedly installed on one end of the connecting rod 13. A protrusion 15 is fixedly installed on one side of the disc 14. A sleeve 16 is movably fitted onto the outer surface of the protrusion 15. A moving rod 17 is fixedly installed at the bottom of the sleeve 16. The bottom of the moving rod 17 extends into the interior of the housing 2 and a moving frame 18 is fixedly installed thereon. A first limit wheel 19 is rotatably installed on the inner side of the moving frame 18. A drive mechanism is fixedly installed on the top of the bracket 10. A second limit wheel 30 is fixedly installed on both sides inside the housing 2. The moving rod 17 is movably connected to the housing 2.

[0027] When the operator uses the device, they first activate the self-locking motor 11 via the controller 7. When the self-locking motor 11 is activated, it drives the rotating frame 12 to rotate. When the rotating frame 12 rotates, it drives the connecting rod 13 to rotate. When the connecting rod 13 rotates, it drives the disc 14 to rotate. When the disc 14 rotates, it drives the protrusion 15 to rotate. When the protrusion 15 rotates, the rotation of the sleeve 16 is restricted by the housing 2, so the rotation of the protrusion 15 drives the sleeve 16 to move up and down. When the sleeve 16 moves up and down, it drives the moving rod 17 to move. As the moving rod 17 moves, it drives the moving frame 18 and the first limiting wheel 19 to move. When both the first limiting wheel 19 and the second limiting wheel 30 are in contact with the PET film, the self-locking motor 11 can be turned off, thereby limiting the PET film.

[0028] The controller 7 starts the self-locking motor 11, which drives the rotating frame 12 to rotate, thereby driving the disc 14 and the protrusion 15 to rotate, which in turn drives the moving rod 17 to move, which in turn drives the limiting wheel 19 to move, thus limiting the PET film. Compared with the traditional device, this device uses the cooperation of the disc 14 and the protrusion 15 to move the limiting wheel 19. Compared with the traditional device, which uses a spring assembly to limit the PET film, the spring is prone to deformation when subjected to force, resulting in unstable limiting of the PET film. However, this device uses the cooperation of the disc 14 and the protrusion 15 to drive the movement of the limiting wheel 19, making the limiting wheel 19 more stable in limiting the PET film, while improving the convenience of operation and thus improving the working efficiency of the device.

[0029] A rotating mechanism is fixedly installed on one side of the housing 2. A circular plate 23 is fixedly installed on one end of the rotating mechanism. A rotating roller 24 is fixedly installed on one side of the circular plate 23. A limiting plate 25 is fixedly installed on one end of the rotating roller 24. A threaded rod 27 is rotatably installed on one side of the limiting plate 25. One end of the threaded rod 27 passes through the upper and lower sides of the limiting plate 25. A knob 26 is fixedly sleeved on the outer surface of the threaded rod 27. A threaded sleeve 28 is threadedly sleeved on the outer surface of the threaded rod 27. A friction plate 29 is fixedly installed on one end of the threaded sleeve 28. One end of the friction plate 29 extends into the interior of the circular plate 23 and is movably connected to the circular plate 23.

[0030] When the operator uses the device, they first attach the membrane sleeve to the outer surface of the rotating roller 24, and then rotate the knob 26. When the knob 26 rotates, it will drive the threaded rod 27 to rotate. When the threaded rod 27 rotates, the rotation of the threaded sleeve 28 is restricted by the circular plate 23, so the rotation of the threaded rod 27 will drive the threaded sleeve 28 to move. When the threaded sleeve 28 moves, it will drive the friction plate 29 to move. When the sides of the two friction plates 29 are in contact with the inner side of the membrane sleeve, the knob 26 can be stopped.

[0031] Rotating the knob 26 drives the threaded rod 27 to rotate, which in turn moves the threaded sleeve 28. The movement of the threaded sleeve 28 then moves the friction plate 29. Compared to traditional devices, this device uses the friction plate 29 to hold the inner side of the film tube in place, preventing slippage between the film tube and the rotating roller 24 during rotation. This prevents the film tube from not rotating and thus ensuring the PET film is properly wound onto it. The friction between the friction plate 29 and the film tube ensures that the rotation of the rotating roller 24 stably drives the rotation of the friction plate 29, thereby improving the device's working efficiency.

[0032] The rotating mechanism includes a base plate 20 fixedly installed on one side of the housing 2, a motor 21 fixedly installed on the top of the base plate 20, a side frame 22 fixedly installed on one side of the housing 2, and one end of the drive shaft of the motor 21 passes through the left and right sides of the side frame 22 and is fixedly connected to the circular plate 23.

[0033] The controller 7 starts the motor 21 to drive the rotation of the circular plate 23, which in turn drives the rotation of the rotating roller 24, and then drives the rotation of the film cylinder.

[0034] The drive mechanism includes a self-locking motor 11 fixedly mounted on the support 10. One end of each of the two drive shafts of the self-locking motor 11 is fixedly mounted with a rotating frame 12, and one end of the rotating frame 12 is fixedly connected to the connecting rod 13.

[0035] The controller 7 starts the self-locking motor 11, which drives the rotating frame 12 to rotate. The rotation of the rotating frame 12 drives the connecting rod 13 to rotate, which in turn drives the disc 14 to rotate.

[0036] Among them, a guide roller 6 is fixedly installed on one side of the box body 2, and a heat dissipation vent 5 is opened on one side of the box body 2.

[0037] The PET film to be dried is guided by guide roller 6, and the internal parts of the device are cooled by heat dissipation port 5.

[0038] Among them, a bottom bracket 8 is fixedly installed on the bottom of the inner side of the box 2, and a circulating dryer 9 is fixedly installed on the top of the bottom bracket 8. There are two circulating dryers 9, and the other circulating dryer 9 is located on the top of the inner side of the box 2 and is fixedly connected to the top of the inner side of the box 2.

[0039] The design of two circulating dryers 9 allows for the drying of both the top and bottom sides of the PET film.

[0040] The cabinet 2 has a side door 3 hinged to one side, a glass plate 4 fixedly installed on one side of the side door 3, and a controller 7 fixedly installed on one side of the cabinet 2. The controller 7 is electrically connected to the self-locking motor 11, the motor 21 and the circulating dryer 9.

[0041] The design of glass plate 4 allows staff to easily observe the internal operation of the device, while the design of controller 7 controls the operation of the device.

[0042] The circulating dryer 9 sends heated air into the interior of the chamber 2, where it comes into contact with the PET film to be dried, removing moisture from the surface of the PET film. The hot air becomes humid air after passing through the material, and before being drawn into the dryer through the air inlet, it usually passes through a circulation channel containing a moisture filtration structure.

[0043] Working principle and usage process of this utility model:

[0044] When the operator uses the device, they first activate the self-locking motor 11 via the controller 7. When the self-locking motor 11 is activated, it drives the rotating frame 12 to rotate. When the rotating frame 12 rotates, it drives the connecting rod 13 to rotate. When the connecting rod 13 rotates, it drives the disc 14 to rotate. When the disc 14 rotates, it drives the protrusion 15 to rotate. When the protrusion 15 rotates, the rotation of the sleeve 16 is restricted by the housing 2, so the rotation of the protrusion 15 drives the sleeve 16 to move up and down. When the sleeve 16 moves up and down, it drives the moving rod 17 to move. As the moving rod 17 moves, it drives the moving frame 18 and the first limiting wheel 19 to move. When both the first limiting wheel 19 and the second limiting wheel 30 are in contact with the PET film, the self-locking motor 11 can be turned off, thereby limiting the PET film.

[0045] When the operator uses the device, they first attach the membrane sleeve to the outer surface of the rotating roller 24, and then rotate the knob 26. When the knob 26 rotates, it will drive the threaded rod 27 to rotate. When the threaded rod 27 rotates, the rotation of the threaded sleeve 28 is restricted by the circular plate 23, so the rotation of the threaded rod 27 will drive the threaded sleeve 28 to move. When the threaded sleeve 28 moves, it will drive the friction plate 29 to move. When the sides of the two friction plates 29 are in contact with the inner side of the membrane sleeve, the knob 26 can be stopped.
