Description

It is widely used in food, medicine, chemical industry and other fields. In the process of processing plastic film, in order to ensure the use effect of plastic film, it is usually necessary to cool the newly produced plastic film. Since the plastic film contains a lot of water during the production and cooling process, it needs to be dried.

Air drying requires heating the cold air to a certain temperature range through a heating wire.

DETAILED DESCRIPTION

[0030] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0031] In the description of the present invention, it is necessary to understand that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0032] Example:

[0033] Reference Figure 1-Figure 7, a plastic film processing device, including a frame 1, and also including a first positioning roller group 39 and a second positioning roller group 40 rotatably connected to the frame 1, the first positioning roller group 39 and the second positioning roller group 40 are vertically arranged, and the second positioning roller group 40 is located above the first positioning roller group 39, and the vibration roller 22 is located between the first positioning roller group 39 and the second positioning roller group 40. It also includes: a cooling unit arranged on the frame 1, used to cool the plastic film, wherein a driving unit is arranged between the frame 1 and the cooling unit, and the driving unit can drive the cooling unit to rotate to transport the plastic film; a dewatering unit arranged on the frame 1, and the driving unit can drive the dewatering unit to reciprocate along the vertical direction of the plastic film to dewater the plastic film; a drying unit arranged on the frame 1, used to dry the dewatered plastic film, wherein the driving unit and the dewatering unit can drive the drying unit to rotate to inhale external cooling air, and a connecting pipe 38 is connected between the cooling unit and the drying unit.

[0034] Reference Figure 1-Figure 3 The cooling unit includes a first water-cooled roller group 2 and a second water-cooled roller group 3, and the first water-cooled roller group 2 and the second water-cooled roller group 3 are fixedly connected with an inner lining roller 4 inside, and a cooling cavity is formed between the first water-cooled roller group 2 and the second water-cooled roller group 3 and the inner lining roller 4, and connecting water pipes 5 are connected at both ends of the inner lining roller 4, and the connecting water pipes 5 extend to the outside of the first water-cooled roller group 2 or the second water-cooled roller group 3 respectively, and a water inlet pipe 6 and a drain pipe 7 are fixedly connected to one side of the frame 1 close to the connecting water pipe 5, wherein the distance between the first water-cooled roller group 2 or the second water-cooled roller group 3 matches the size of the plastic film, the connecting water pipe 5 is connected to the cooling cavity, the connecting water pipe 5 is rotatably connected to the frame 1, the water inlet pipe 6 and the drain pipe 7 are connected to the connecting water pipe 5 in the corresponding direction, and the water inlet pipe 6 close to the first water-cooled roller group 2 and the drain pipe 7 close to the second water-cooled roller group 3 are located on the same side.

[0035] When the plastic film is cooled and shaped, cooling water is discharged through the corresponding water inlet pipe 6. As the cooling water flows, its temperature gradually increases. Therefore, the cooling effect of the plastic film can be improved by flowing cooling water into the first water-cooled roller group 2 and the second water-cooled roller group 3 from different directions. After entering the first water-cooled roller group 2 and the second water-cooled roller group 3, the cooling water will flow through the cooling cavity and finally be discharged through the drain pipe 7 to complete the cooling of the plastic film. Among them, the lining roller 4 can reduce the size of the cooling cavity (since the cooling of the plastic film mainly depends on the cooling water close to the surface of the first water-cooled roller group 2 and the second water-cooled roller group 3, if the size of the cooling cavity is large, it may happen that after the cooling water flows, the temperature of the cooling water close to the axis changes less, resulting in serious waste of cooling water and low utilization rate). The lining roller 4 is fixedly connected to the first water-cooled roller group 2 and the second water-cooled roller group 3 by a rod, which not only ensures the stability of the lining roller, but also does not affect the flow of cooling water.

[0036] Reference Figure 3-Figure 5 The driving unit includes a driving motor 8 fixedly connected to the frame 1, a driving wheel 9 is fixedly connected to the output end of the driving motor 8, a driven wheel 10 is fixedly connected to one group of connecting water pipes 5 near the first water-cooled roller group 2, a first belt 11 is sleeved between the driving wheel 9 and the driven wheel 10, a linkage gear 12 is fixedly connected to the connecting water pipe 5 away from the driven wheel 10, a first linkage wheel 13 and a second linkage wheel 14 are respectively fixedly connected to the connecting water pipe 5 near the driven wheel 10, a second belt 15 is sleeved between the first linkage wheel 13 and the second linkage wheel 14, wherein the linkage gears 12 near the first water-cooled roller group 2 or the second water-cooled roller group 3 are meshed with each other.

[0037] It should be explained that, since the temperature of the newly produced plastic film is relatively high and the plasticity is relatively large, it needs to be transported by the first water-cooled roller group 2 and the second water-cooled roller group 3 to prevent it from being severely deformed during the cooling process. When the driving motor 8 drives one of the first water-cooled roller groups 2 to rotate under the action of the driving wheel 9, the driven wheel 10 and the first belt 11, the first water-cooled roller group 2 can be driven to rotate synchronously and relatively under the action of the linkage gear 12, and then the second water-cooled roller group 3 is driven to rotate through the first linkage wheel 13, the second linkage wheel 14 and the second belt 15, so that the plastic film is more stable when being transported between the first water-cooled roller group 2 and the second water-cooled roller group 3.

[0038] Reference Figure 1 , Figure 2 and Figure 6 The dewatering unit includes a fixed frame 18 symmetrically fixedly connected to the frame 1, a slide groove 19 is opened on the fixed frame 18, a spring 20 is fixedly connected inside the slide groove 19, a slider 21 slidably connected to the slide groove 19 is fixedly connected to the end of the spring 20, a vibration roller 22 is rotatably connected between the two groups of sliders 21, a push block 23 is fixedly connected to the side of the slider 21 away from the vibration roller 22, a connecting shaft 24 is rotatably connected between the two groups of fixed frames 18, and a first pulley 25 and a cam 26 are symmetrically fixedly connected to the connecting shaft 24, wherein the vibration roller 22 is in contact with the plastic film, and the cam 26 and the push block 23 are located on the same plane.

[0039] During the conveying process of the plastic film, the second pulley 27 is driven to rotate through the driven gear 17, thereby driving the first pulley 25 and the cam 26 to rotate. When the cam 26 contacts the pushing block 23, it drives the vibration roller 22 to move toward the side of the plastic film. When the cam 26 is separated from the pushing block 23, the vibration roller 22 moves to the initial position under the action of the spring 20. Repeating the above process can make the plastic film vibrate during the conveying process. By means of vibration, not only the moisture on the surface of the plastic film can be separated, but also some of the moisture adsorbed inside the plastic film can be separated, so as to facilitate During the subsequent drying of the plastic film, the detached moisture will fall onto the plastic film between the first water-cooled roller group 2 and the second water-cooled roller group 3, accelerating the cooling of the plastic film. It should be explained that during this process, the first positioning roller group 39 and the second positioning roller group 40 can position the plastic film. In addition, the vibration roller 22 moves a small distance and will not cause deformation of the plastic film. Secondly, the rotation speed of the cam 26 can be achieved by adjusting the diameter ratio of the linkage gear 12 and the driven gear 17 or the diameter ratio between the second pulley 27 and the first pulley 25.

[0040] Reference Figure 1 , Figure 2 , Figure 3 and Figure 7 The drying unit includes a drying device 29 symmetrically fixedly connected to the frame 1, and the side of the drying device 29 away from each other is connected with an air inlet pipe 30, and a fan is arranged inside the air inlet pipe 30. The side of the drying device 29 close to each other is connected with an air outlet 31, wherein the drying device 29 is inclined and located between the first positioning roller group 39 and the second positioning roller group 40, and a linkage mechanism connected to the fan is arranged on the air inlet pipe 30, and a preheating mechanism is arranged on the outer wall of the air inlet pipe 30, and the linkage mechanism includes a drive shaft 35 rotatably connected to the air inlet pipe 30 and connected to the fan, and the end of the drive shaft 35 away from the air inlet pipe 30 A connecting wheel 36 is fixedly connected, and a fourth belt 37 is sleeved between one group of connecting wheels 36 and the first pulley 25 in the corresponding direction. The linkage mechanism also includes a rotating shaft 16 rotatably connected to the frame 1 near the second water-cooled roller group 3. The end of the rotating shaft 16 near the second water-cooled roller group 3 is fixedly connected to a driven gear 17, and the end of the rotating shaft 16 away from the driven gear 17 is fixedly connected to a second pulley 27, wherein the driven gear 17 and one group of linkage gears 12 near the second water-cooled roller group 3 are meshed with each other, and a third belt 28 is sleeved between the second pulley 27 and the first pulley 25 and the connecting wheel 36 in the corresponding direction.

[0041] The drying device 29 and the fan are conventional means in the prior art, so they are not described in detail. The external cold air can be sucked into the drying device 29 through the fan, and after heating, it is blown toward the plastic film through the air outlet 31 to achieve drying of the plastic film. In this process, the first pulley 25 and the connecting wheel 36 in different directions can drive the drive shaft 35 to rotate, thereby driving the fan to rotate, and the speed of the fan can be adjusted by adjusting the first pulley 25 and the connecting wheel 36. In addition, according to the conveying speed of the plastic film, the wind force can also be automatically adjusted to avoid over-drying or under-drying of the plastic film and improve the drying effect of the plastic film.

[0042] Reference Figure 2 and Figure 7 The preheating mechanism is fixedly connected to the heat exchange sleeve 32 on the air inlet pipe 30, and a water inlet 33 and a drain port 34 are provided on the outside of the heat exchange sleeve 32. The drain pipe 7 close to the first water-cooled roller group 2 and the second water-cooled roller group 3 is connected to the water inlet 33 in the corresponding direction through a connecting pipe 38.

[0043] The water temperature will rise after being cooled, and enter the heat exchange sleeve 32 in the corresponding direction through the drain pipe 7, the connecting pipe 38 and the water inlet 33. When the cold air enters the drying device 29 through the air inlet pipe 30, the water can heat the air, and the air can also cool the water. This not only reduces the output power of the drying device 29 for heating the air, but also reduces the energy consumption of the compressor when the water is reused, greatly reducing the processing cost of the plastic film, and being more energy-saving and environmentally friendly.

[0044] A plastic film processing device, when in use, refers to the following process:

[0045] Step 1: First, the produced plastic film is passed through the first water-cooled roller group 2, the second water-cooled roller group 3, the first positioning roller group 39 and the second positioning roller group 40 in sequence, and finally passed through the winding device for winding;

[0046] After cooling and shaping, the plastic film is transported mainly by the tension of the winding device, which can ensure the effect of water removal and drying of the plastic film;

[0047] Step 2: Start the driving unit to drive the first water-cooled roller group 2 and the second water-cooled roller group 3 to rotate, so as to convey the plastic film, and at the same time, cool the plastic film through the first water-cooled roller group 2 and the second water-cooled roller group 3 to shape it;

[0048] Before cooling and shaping, the plastic film is transported mainly by the rotation of the first water-cooled roller group 2 and the second water-cooled roller group 3 to prevent severe deformation during cooling;

[0049] Step 3: When the shaped plastic film passes through the dewatering unit, the driving unit drives the dewatering unit to move back and forth in the vertical direction of the plastic film, driving the plastic film to vibrate and accelerate the separation of water in the plastic film, so as to facilitate the subsequent drying of the plastic film;

[0050] Vibration can not only remove moisture from the surface of the plastic film, but also remove some moisture adsorbed inside the plastic film;

[0051] Step 4: The fan in the drying unit is driven by the driving unit and the dehumidification unit to draw in the cold air from the outside, and after heating it to a specific temperature, the plastic film is dried to remove moisture;

[0052] Step 5: In addition, the water temperature rises after cooling and enters the preheating mechanism to preheat the cold air, reducing the output power of the drying unit to achieve energy saving. At the same time, the cold air can cool the water to facilitate subsequent cooling and reuse of the water.

[0053] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
