Description

Technical Field

[0001] This utility model relates to the field of polyester film processing technology, specifically to a dust collection mechanism for a polyester film processing production line. Background Technology

[0002] Polyester film is a high-performance polymer material with high mechanical strength and high transparency. With the continuous development of its functions, its application fields have gradually expanded from packaging and printing to industries such as electronics, optical display, new energy, consumer electronics, and automobiles.

[0003] A search revealed a utility model patent with Chinese patent publication number CN215278703U, which discloses a dust removal device for polyester film production. The device includes a first dust removal chamber and a second dust removal chamber. The first dust removal chamber has a first dust removal roller and a second dust removal roller arranged on both sides of the polyester film. The first dust removal roller and the second dust removal roller are respectively provided with a first dust removal brush and a second dust removal brush in the circumferential direction. A dust suction mechanism is provided above the first dust removal roller and below the second dust removal roller.

[0004] The aforementioned device removes dust through a first dust removal roller and a second dust removal roller. As the dust removal rollers clean the dust removal chamber, dust will fly around. Since the dust collection mechanism is relatively far away, some dust will inevitably be missed, resulting in secondary pollution. Utility Model Content

[0005] The purpose of this invention is to provide a dust collection mechanism for a polyester film processing production line to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a dust collection mechanism for a polyester film processing production line, comprising a base plate, two support frames fixedly connected to the top outer wall of the base plate, the two support frames being rotatably connected to a horizontally arranged mounting frame, a dust collection assembly installed inside the mounting frame, the dust collection assembly comprising two horizontally arranged dust collection pipes fixedly connected inside the mounting frame, a collection nozzle provided on one side of the outer wall of each of the two dust collection pipes, the two collection nozzles being arranged close to each other, and a cleaning nozzle provided on one side of the outer wall of each of the two dust collection pipes, the two cleaning nozzles being arranged far apart from each other.

[0007] As a further preferred embodiment of this technical solution, a connecting pipe is fixedly inserted into the outer wall of each of the two dust suction pipes at their far ends. A collection box is fixedly installed at one end of the top outer wall of the base plate. Both connecting pipes are fixedly inserted into the inside of the collection box. A filter cartridge is installed on the inner wall of one end of the collection box cover, and a fan is fixedly installed on the outer wall of one end of the cover. The fan is connected to the filter cartridge.

[0008] When dust is intercepted and pushed to one side, it can collect the dust in a timely manner and clean the dust outside the cleaning cloth, effectively preventing secondary pollution. When the fan inside the collection box is started, the collection box draws the dust from inside the suction pipe outward through the connecting pipe. The collection nozzle and cleaning nozzle outside the suction pipe will continuously generate suction. When the dust is pushed towards the suction pipe by the cleaning cloth, the outside air will bring the flying dust into the suction pipe. When the dusty part of the cleaning cloth passes through the cleaning nozzle, the outside air entering the cleaning nozzle will wash the surface of the cleaning cloth, and the dust will be cleaned. The dusty air enters the collection box through the connecting pipe and is finally drawn to the outside by the fan. The filter cartridge can intercept the dust in the airflow, thus continuing the process.

[0009] As a further preferred embodiment of this technical solution, the mounting frame is equipped with a cleaning assembly, which includes two cleaning rollers rotatably connected inside the mounting frame. A cleaning cloth is fixedly sleeved on the outside of each of the two cleaning rollers. Two suction pipes are respectively located on one side of the two cleaning rollers. A gear is coaxially fixed at the output end of each of the two cleaning rollers, and the two gears mesh with each other. A motor is fixedly installed on the inner wall of one end of the mounting frame, and the output end of the motor is coaxially fixed with one end of the upper cleaning roller.

[0010] As a further preferred embodiment of this technical solution, a worm gear is coaxially fixed at one end of the outer circumference of the mounting frame, and an extension plate is provided on both outer walls of one of the support frames. The two extension plates are rotatably connected to the same worm, and the worm meshes with the worm gear.

[0011] The worm gear is started to rotate by a handle at its end. The worm gear drives the worm wheel to rotate through meshing, and the mounting frame connected to it is driven to rotate synchronously. The cleaning rollers inside the mounting frame move towards a horizontal position until the cleaning cloths on both sides are in contact with the front and back of the film, respectively. This allows the device to adapt to cleaning films of different thicknesses and also to tighten the film, keeping it taut and improving the cleaning effect. The motor inside the mounting frame is started, and the motor output drives the top cleaning roller to rotate clockwise. The gear at the end of the cleaning roller rotates synchronously. This gear, through a gear meshing with it, drives the other cleaning roller to rotate counterclockwise, ensuring that as the film passes through the cleaning rollers, the dust on it is intercepted and pushed to the same side.

[0012] As a further preferred embodiment of this technical solution, the collecting nozzle is made of antistatic dust-free cloth.

[0013] As a further preferred embodiment of this technical solution, the collecting nozzle is made of antistatic dust-free cloth, and the parts of the two connecting tubes that are close to each other are made of steel wire hose.

[0014] As a further preferred embodiment of this technical solution, two horizontally arranged static eliminators are installed on the top outer wall of the base plate via a support frame.

[0015] This utility model provides a dust collection mechanism for a polyester film processing production line, which has the following beneficial effects:

[0016] (1) By setting up a dust collection component, this utility model can collect dust in a timely manner when it is intercepted and pushed to one side, and can also clean the dust outside the cleaning cloth, effectively avoiding secondary pollution caused by dust. When the fan inside the collection box is started, the collection box draws the dust pipe outward through the connecting pipe. The collection nozzle and cleaning nozzle outside the dust pipe will continuously generate suction. When the dust is pushed towards the dust pipe by the cleaning cloth, the outside air will bring the flying dust into the dust pipe. When the dusty part of the cleaning cloth passes through the cleaning nozzle, the air entering the cleaning nozzle will wash the surface of the cleaning cloth. The dust will be cleaned by impact. The dusty air enters the collection box through the connecting pipe and is finally drawn to the outside by the fan. The filter cartridge can intercept the dust in the airflow, thus continuously.

[0017] (2) This utility model sets up a cleaning component, which is driven to start rotating by the handle at the end of the worm gear. The worm gear drives the worm wheel to rotate through meshing, and the mounting frame connected to it is driven to rotate synchronously. The cleaning roller inside the mounting frame changes to a horizontal state until the cleaning cloth outside the two is attached to the front and back of the film respectively, so that the device can adapt to the cleaning of films of different thicknesses and can also play the effect of tightening the film, keeping the film in a taut state, which is conducive to improving the cleaning effect. Start the motor inside the mounting frame, and the output end of the motor drives the top cleaning roller to rotate clockwise. The gear at the end of the cleaning roller rotates synchronously. This gear can drive the other cleaning roller to rotate counterclockwise through the gear meshing with it, ensuring that when the film passes through the cleaning roller, the dust on it will be intercepted and pushed to the same side.

[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0024] This utility model provides a technical solution: such as Figure 1 and Figure 4 As shown in this embodiment, a dust collection mechanism for a polyester film processing production line includes a base plate 1. Two support frames 2 are fixedly connected to the top outer wall of the base plate 1. The two support frames 2 are rotatably connected to the same horizontally arranged mounting frame 3. A dust collection component 4 is installed inside the mounting frame 3. The dust collection component 4 includes two horizontally arranged dust collection pipes 401 fixedly connected inside the mounting frame 3. A collection nozzle 402 is provided on one side of the outer wall of each of the two dust collection pipes 401, and the two collection nozzles 402 are arranged close to each other. A cleaning nozzle 403 is provided on one side of the outer wall of each of the two dust collection pipes 401, and the two cleaning nozzles 403 are arranged far apart from each other.

[0025] Two suction pipes 401 are each fixedly connected to a connecting pipe 404 at their opposite ends. A collection box 405 is fixedly installed at one end of the top outer wall of the base plate 1. Both connecting pipes 404 are fixedly inserted into the inside of the collection box 405. A filter cartridge 406 is installed on the inner wall of one end of the cover of the collection box 405, and a fan 407 is fixedly installed on the outer wall of one end of the cover. The fan 407 is connected to the filter cartridge 406.

[0026] The fan 407 inside the housing 405 is activated. The housing 405 draws the dust from the inside of the suction pipe 401 outward through the connecting pipe 404. The collection nozzle 402 and cleaning nozzle 403 on the outside of the suction pipe 401 continuously generate suction. When the dust is pushed towards the suction pipe 401 by the cleaning cloth 502, the outside air carries the flying dust into the suction pipe 401. When the dusty part of the cleaning cloth 502 passes through the cleaning nozzle 403, the air entering the cleaning nozzle 403 will wash the surface of the cleaning cloth 502, and the dust will be cleaned. The dusty air enters the housing 405 through the connecting pipe 404 and is finally drawn to the outside by the fan 407. The filter cartridge 406 can intercept the dust in the airflow, thus continuing the process.

[0027] like Figure 1 and Figure 2As shown, the mounting frame 3 is equipped with a cleaning assembly 5. The cleaning assembly 5 includes two cleaning rollers 501 rotatably connected inside the mounting frame 3. A cleaning cloth 502 is fixedly sleeved on the outside of each of the two cleaning rollers 501. Two suction pipes 401 are respectively located on one side of the two cleaning rollers 501. A gear 504 is coaxially fixed at the output end of each of the two cleaning rollers 501. The two gears 504 mesh with each other. A motor 503 is fixedly installed on the inner wall of one end of the mounting frame 3. The output end of the motor 503 is coaxially fixed with one end of the upper cleaning roller 501.

[0028] A worm gear 506 is coaxially fixed at one end of the outer circumference of the mounting bracket 3. An extension plate 505 is provided on both sides of the outer wall of one of the support frames 2. The same worm 507 is rotatably connected between the two extension plates 505, and the worm 507 meshes with the worm gear 506.

[0029] The worm gear 507 is started to rotate by the handle at the end of the worm. The worm gear 507 drives the worm wheel 506 to rotate through meshing. The mounting frame 3 connected to it is driven to rotate synchronously. The cleaning roller 501 inside the mounting frame 3 changes to a horizontal state until the cleaning cloth 502 on the outside of the two rollers is in contact with the front and back of the film respectively. This allows the device to adapt to the cleaning of films of different thicknesses and also to tighten the film, keeping it taut and improving the cleaning effect. The motor 503 inside the mounting frame 3 is started. The output end of the motor 503 drives the top cleaning roller 501 to rotate clockwise. The gear 504 at the end of the cleaning roller 501 rotates synchronously. This gear 504, through its meshing gear 504, drives the other cleaning roller 501 to rotate counterclockwise, ensuring that when the film passes through the cleaning roller 501, the dust on it is intercepted and pushed to the same side.

[0030] like Figure 1 and Figure 2 As shown, the collection nozzle 402 is made of antistatic cleanroom cloth. The antistatic cleanroom cloth is made of special fiber material, which can easily absorb and remove dust and particles from the surface of objects. With just a light wipe, it can be restored to its clean state.

[0031] like Figure 1 and Figure 2 As shown, the collection nozzle 402 is made of anti-static clean cloth. The two connecting tubes 404 are made of steel wire hoses when they are close to each other, so that they will not affect the movement of the suction tube 401.

[0032] like Figure 1 and Figure 2 As shown, two horizontally arranged static eliminators 6 (preferably model IZS31-300C) are installed on the top outer wall of the base plate 1 via a support frame. These eliminators can generate positive and negative ions, which neutralize the static charge on the surface of the thin film, thereby eliminating static electricity.

[0033] This utility model provides a dust collection mechanism for a polyester film processing production line, and its specific working principle is as follows:

[0034] When the device is in operation, the polyester film from the external unwinding device is passed through two cleaning rollers 501 and fixed to the external winding rollers. The handle at the end of the worm gear 507 drives it to rotate. The worm gear 507, through meshing, drives the worm wheel 506 to rotate, causing the connected mounting frame 3 to rotate synchronously. The cleaning rollers 501 inside the mounting frame 3 move towards a horizontal position until the cleaning cloths 502 on both sides of the film are in contact with the front and back sides respectively. This allows the device to adapt to cleaning films of different thicknesses and also to tighten the film, keeping it taut and improving the cleaning effect. The motor 503 inside the mounting frame 3 is then started. The output of the motor 503 drives the top cleaning roller 501 to rotate clockwise. The gear 504 at the end of the cleaning roller 501 rotates synchronously. This gear 504, through its meshing with another gear 504, drives the other cleaning roller. Rotating counterclockwise ensures that dust on the film is intercepted and pushed to the same side when it passes through the cleaning roller 501. The fan 407 inside the collection box 405 is activated. The collection box 405 draws the dust suction pipe 401 outward through the connecting pipe 404. The collection nozzle 402 and cleaning nozzle 403 outside the dust suction pipe 401 continuously generate suction. When the dust is pushed towards the dust suction pipe 401 by the cleaning cloth 502, the outside air carries the flying dust into the dust suction pipe 401. When the dusty part of the cleaning cloth 502 passes through the cleaning nozzle 403, the air entering the cleaning nozzle 403 will wash the surface of the cleaning cloth 502, and the dust will be cleaned. The dusty air enters the collection box 405 through the connecting pipe 404 and is finally drawn to the outside by the fan 407. The filter cartridge 406 can intercept the dust in the airflow, thus continuing the process.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
