Description

Technical Field

[0001] This utility model relates to the field of composite film processing technology, and specifically to a calendering device for composite film processing. Background Technology

[0002] Composite film is a type of film produced through processes such as extrusion, calendering, cooling, and winding. Calendering is an important processing step in composite film processing to ensure uniform film texture. Currently, most calendering devices for composite film processing on the market use the mutual movement of two rollers to squeeze and stretch the composite film.

[0003] A Chinese public utility model patent (CN218196472U) discloses a calendering device for a TPU composite film production line, relating to the technical field of TPU composite film production equipment. The device includes a base plate with two sets of support frames welded to its top. A second roller is rotatably connected between the two sets of support frames. Above the second roller is a first roller movably connected to the support frames. Movable sleeves, extending into the support frames, are fitted at both ends of the first roller. Two sets of support arms are fixed to one side of the support frames at the top of the base plate. An air-jet frame is welded between the two sets of support arms, and the air-jet frame has a cavity inside. This utility model, through the coordinated arrangement of a turntable, lead screw, movable sleeve, and driven block, allows the turntable to rotate, causing the lead screw to rotate accordingly. The driven block then raises the movable sleeve along the stroke groove, adjusting the interval between the first and second rollers. This allows for the calendering of TPU composite films of different thicknesses, expanding the applicability of the device.

[0004] However, in implementing the relevant technology, the calendering device of the above-mentioned composite film production line was found to have the following problems: In the existing technology, dust on the upper and lower surfaces of the composite film is removed by blowing out gas, but the blown dust is suspended in the air and easily falls back onto the composite film. Therefore, a calendering device for composite film processing is proposed. Utility Model Content

[0005] This invention proposes a calendering device for composite film processing, which solves the problem in related technologies where blown dust is suspended in the air and easily falls back onto the composite film.

[0006] The technical solution of this utility model is as follows: A calendering apparatus for composite film processing, comprising:

[0007] A support plate, a U-shaped frame and a dust collection frame are fixedly installed on the top of the support plate, and U-shaped plates are slidably connected to both sides of the inner wall of the U-shaped frame. A driving component is fixedly installed on one side of the U-shaped plate and one side of the U-shaped frame. A calendering roller is rotatably connected to both sides of the inner wall of the U-shaped plate and the U-shaped frame. The output end of the driving component is connected to the calendering roller.

[0008] An air blowing assembly is disposed on the top of a support plate and is used to blow away and remove dust from the upper and lower surfaces of the composite membrane.

[0009] Filter plate one, the filter plate one is detachably connected to the inside of the dust collection frame;

[0010] A water tank is fixedly installed at the bottom of the support plate, and an air extraction component is provided through the top of the water tank. One end of the air extraction component is connected to the dust collection frame.

[0011] Preferably, the air blowing assembly includes a vertical plate, an air pump, and a nozzle. The vertical plate is located at the top of the support plate, the air pump is located on one side of the vertical plate, and the output end of the air pump passes through the vertical plate and is connected to the nozzle.

[0012] Preferably, the exhaust assembly includes an exhaust fan, a first pipe, and a second pipe. The exhaust fan is located at the top of the water tank. The exhaust end of the exhaust fan is connected to the first pipe. One end of the first pipe is connected to the dust collection frame. The exhaust end of the exhaust fan passes through the water tank and is connected to the second pipe.

[0013] Preferably, a filter plate two is fixedly installed inside the water tank, and the bottom end of the pipe two extends to the bottom of the filter plate two.

[0014] Preferably, a threaded rod is installed through the top of the U-shaped frame, and the bottom end of the threaded rod is rotatably connected to the top of the U-shaped plate.

[0016] Preferably, threaded blocks are fixedly installed on both sides of the dust collection frame, and the threaded rod is threadedly connected to the threaded blocks.

[0017] The working principle and beneficial effects of this utility model are as follows:

[0018] The system consists of an air blowing component, an air extraction component, a dust collection frame, a filter plate, and a water tank. The air blowing component blows out gas, removing dust from the upper and lower surfaces of the composite membrane. This creates dusty gas that is suspended in the air. The air extraction component is then activated, and the suspended dusty gas is drawn in by the dust collection frame. The dusty gas is first filtered through the filter plate. Any dusty gas that cannot be completely filtered passes through the water tank of the air extraction component, where water fully degrades the dust. This effectively prevents most of the blown-out dust from remaining suspended in the air and easily falling back onto the composite membrane. Attached Figure Description

Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0026] Please see Figure 1 - Figure 4 The present invention provides a calendering apparatus for processing composite films, comprising:

[0027] Support plate 1, U-shaped frame 2 and dust collection frame 7 are fixedly installed on the top of support plate 1 respectively, U-shaped plate 3 is slidably connected to both sides of the inner wall of U-shaped frame 2, drive component 4 is fixedly installed on one side of U-shaped plate 3 and U-shaped frame 2 respectively, calendering roller 5 is rotatably connected to both sides of the inner wall of U-shaped plate 3 and U-shaped frame 2 respectively, and the output end of drive component 4 is connected to calendering roller 5.

[0028] Air blowing assembly 6 is set on the top of support plate 1. Air blowing assembly 6 is used to blow out and remove dust from the upper and lower surfaces of the composite film.

[0029] Filter plate 9 is detachably connected to the inside of the dust collection frame 7;

[0030] Water tank 8 is fixedly installed at the bottom of support plate 1. A suction component 10 is provided through the top of water tank 8, and one end of suction component 10 is connected to dust collection frame 7.

[0031] The exhaust assembly 10 includes an exhaust fan 101, a first pipe 102 and a second pipe 103. The exhaust fan 101 is located on top of the water tank 8. The exhaust end of the exhaust fan 101 is connected to the first pipe 102. One end of the first pipe 102 is connected to the dust collection frame 7. The exhaust end of the exhaust fan 101 passes through the water tank 8 and is connected to the second pipe 103.

[0032] A filter plate 2 15 is fixedly installed inside the water tank 8, and the bottom end of the pipe 2 103 extends to the bottom of the filter plate 2 15.

[0033] In use, clean water is added to the water tank 8 until the water level is higher than the filter plate 15. The composite membrane is passed through the calendering rollers 5. The output end of the drive unit 4 drives the calendering rollers 5 to rotate and calender the composite membrane. The drive unit 4 is a servo motor in the prior art. The air blowing component 6 is started, and the gas blows out to blow away the dust on the upper and lower surfaces of the composite membrane. At this time, dust gas will be generated and suspended in the air. The exhaust fan 101 is started, and the dust gas suspended in the air is adsorbed by the dust collection frame 7. The dust gas is first filtered through the filter plate 9. The dust gas that cannot be completely filtered enters the water tank 8 through the pipe 102 and the pipe 203. Since the filter plate 15 is set at an angle, the contact time between the dust gas and the water is increased, and the dust is fully degraded by the water. Then the gas is discharged through the exhaust pipe on one side of the water tank 8.

[0034] Specifically, the air blowing assembly 6 includes a vertical plate 61, an air pump 62, and a nozzle 63. The vertical plate 61 is located at the top of the support plate 1, and the air pump 62 is located on one side of the vertical plate 61. The output end of the air pump 62 passes through the vertical plate 61 and is connected to the nozzle 63.

[0035] The air pump 62 starts to deliver gas to the nozzle 63 and blows it out to remove dust from the upper and lower surfaces of the composite membrane.

[0036] Specifically, a threaded rod 11 is installed through the top of the U-shaped frame 2, and the bottom end of the threaded rod 11 is rotatably connected to the top of the U-shaped plate 3.

[0037] Rotating the threaded rod 11 causes the U-shaped plate 3 to rise and fall, making it easy to adjust the appropriate distance between the calendering rollers 5.

[0038] Specifically, a connecting plate 12 is fixedly installed on the top of the filter plate 9, and a threaded rod 13 is installed through the top of the connecting plate 12. Threaded blocks 14 are fixedly installed on both sides of the dust collection frame 7, and the threaded rod 13 and the threaded blocks 14 are threadedly connected.

[0039] When there is a lot of dust on the surface of filter plate 9, it will fall into the dust box inside the dust collection frame 7. The dust box can be pulled out to discharge the dust. When cleaning the dust on the surface of filter plate 9, rotate the threaded rod 13 to disengage it from the threaded block 14, and move the connecting plate 12 upward to facilitate the removal of filter plate 9 to clean the dust on its surface.

[0040] The above are merely preferred embodiments of the present utility model and are 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 shall be included within the protection scope of the present utility model.
