Description

Technical Field

[0001] This utility model relates to the field of polyester film production technology, and in particular to a dust removal device for producing polyester film. Background Technology

[0002] Polyester film is widely used in film application, decoration, and other fields. The surface of the polyester film must be kept dust-free to ensure the product's effectiveness. Although polyester film production takes place in a cleanroom, some dust inevitably remains in the air. Therefore, dust removal treatment is still necessary to ensure the polyester film surface remains dust-free.

[0003] The current conventional dust removal method is to pass the polyester film between the sticky rollers and use the stickiness of the rollers to remove the dust from the surface of the polyester film. However, the dust on the surface of the sticky rollers will increase with the use time. When the dust on the surface of the sticky rollers increases to a certain extent, the machine needs to be stopped and a new sticky roller needs to be replaced before polyester film production can continue, which affects the production efficiency of polyester film. Utility Model Content

[0004] To address the shortcomings of existing dust removal methods that require machine shutdown for replacing the adhesive rollers, which affects production efficiency, this invention proposes a dust removal device that allows for roller replacement without machine shutdown and does not affect polyester film production efficiency.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A dust removal device for producing polyester film includes a rotary mechanism, a mounting base, and a dust-adhesive roller. The rotary mechanism drives the mounting base to move along an elongated rotary path. The upper and lower sides of the rotary path are parallel to the direction of movement of the polyester film. A working position is provided at the lower rear end of the rotary path, and a spare position is provided at the upper front end of the rotary path. A mounting base is provided at both the working position and the spare position. The dust-adhesive roller is rotatably connected to the mounting base. The dust-adhesive roller at the working position is in contact with the polyester film.

[0006] With the above setup, one sticky roller is in use and one is on standby. When the working sticky roller needs to be replaced, the standby sticky roller takes over, so that the machine does not need to be stopped when replacing the sticky roller, thereby reducing the impact on production.

[0007] Furthermore, the rotary mechanism includes a transmission chain, a sprocket, a first motor, a connecting sleeve, and a connecting shaft. The sprocket supports both ends of the transmission chain, and the connecting shaft is installed on the outside of the transmission chain through the connecting sleeve. The dust-adhesive rollers are installed on both ends of the connecting shaft through mounting seats. The first motor drives the sprocket to drive the mounting seats to move along the rotary path.

[0008] With the above setup, the first motor drives the mounting base via a sprocket and transmission chain.

[0009] Furthermore, the rotary mechanism also includes guide rails located on the left and right sides of the transmission chain. The guide rails are provided with grooves, and the mounting base is provided with two sliding shafts that are adapted to the grooves. The sliding shafts are slidably connected in the grooves.

[0010] The above settings improve the stability of the mounting base on the rotation path.

[0011] Furthermore, the mounting base includes a base, a guide rod, a spring, and a connecting seat. The base is fixedly connected to the end of the connecting shaft, the sliding shaft is fixedly connected to the base, the guide rod is perpendicular to the rotation path, the guide rod passes through the base and is slidably connected to the base, the connecting seat is located on the side of the base away from the transmission chain and is fixedly connected to the guide rod, the spring is installed between the base and the connecting seat, and the end of the dust roller is rotatably connected to the connecting seat.

[0012] The above settings allow the adhesive roller to float up and down, ensuring stable contact between the adhesive roller and the polyester film.

[0013] Furthermore, the connecting seat includes a fixed seat, a movable seat, and fasteners. The fixed seat is fixedly connected to the guide rod. The fixed seat has a first semi-circular groove on the side away from the guide rod, and the movable seat has a second semi-circular groove. The movable seat is locked onto the fixed seat by the fasteners. The first and second semi-circular grooves cover the end of the sticky roller.

[0014] The above settings make it easy to replace the adhesive roller.

[0015] Furthermore, the guide rail is fixedly connected to the ground via columns.

[0016] Furthermore, the dust removal device also includes a support belt, support wheels, and a second motor. The support belt supports the lower side of the polyester film, the support wheels support both ends of the support belt, and the device is driven by the second motor.

[0017] With the above setup, the support belt supports the polyester film, facilitating dust removal from one side. Attached Figure Description

[0021] Figure 4 This is a schematic diagram illustrating the movement of the rotating mechanism driving the mounting base in an embodiment. Detailed Implementation

[0022] The technical solution of this utility model will be further described in detail below through embodiments and in conjunction with the accompanying drawings.

[0023] like Figures 1 to 4 A dust removal device for producing polyester film includes a rotary mechanism 3, a mounting base 4, and a dust-adhesive roller 5. The rotary mechanism 3 drives the mounting base 4 to move along an elongated rotary path. The upper and lower sides of the rotary path are parallel to the direction of movement of the polyester film 6. A working position is provided at the lower rear end of the rotary path, and a spare position is provided at the upper front end of the rotary path. The mounting base 4 is provided at both the working position and the spare position. The dust-adhesive roller 5 is rotatably connected to the mounting base 4. The dust-adhesive roller 5 at the working position is in contact with the polyester film.

[0024] With the above setup, one sticky roller 5 is in use and one is on standby. When the working sticky roller 5 needs to be replaced, the standby sticky roller 5 takes over the work, so that the machine does not need to be stopped when replacing the sticky roller 5, thereby reducing the impact on production.

[0025] Specifically, the working principle of the dust removal device in this application is as follows: assuming the polyester film moves horizontally forward, when dust removal is needed on the upper side of the polyester film, the dust removal device is installed on the upper side; when dust removal is needed on the lower side, the dust removal device is installed on the lower side; and when dust removal is needed on both sides, dust removal devices are symmetrically installed on the upper and lower sides of the polyester film. In this embodiment, the working principle of the dust removal device is explained using the removal of dust from the upper side of the polyester film as an example. Figure 2 and Figure 3 Initially, the lower side of the adhesive roller 5 in the working position abuts against the upper side of the polyester film. As the polyester film moves forward, the adhesive roller 5 rotates passively under its adhesive action, simultaneously removing the dust from the upper side of the polyester film. At this time, the adhesive roller 5 in the spare position serves as a backup, located on the upper side of the rotation path, not in contact with the polyester film, keeping its surface clean. As the dust removal time increases, the dust on the surface of the adhesive roller 5 in the working position increases, and its adhesiveness decreases. When it is necessary to replace the adhesive roller 5, the rotation mechanism 3 drives the mounting base 4 in both the working position and the spare position to move clockwise along the rotation path synchronously. The sticky roller 5 moves upward away from the working position and separates from the polyester film, while the mounting seat 4 in the spare position moves downward away from the spare position and comes into contact with the polyester film. During this process, the polyester film continues to move forward. Since the spare position is located in front of the working position, when the sticky roller 5 in the spare position comes into contact with the polyester film, it can promptly intercept the dust on the polyester film, preventing any dust from being missed. The rotary mechanism 3 continues to drive the mounting seat 4 to move until the mounting seat 4 in the spare position is driven to the working position, and the mounting seat 4 in the working position is driven to the spare position. That is, the sticky rollers 5 in the working position and the spare position are swapped, and the dust removal device returns to its working state. Figure 3 At this time, the dust roller 5 in the spare position has a lot of dust on it, and the staff can replace it with a new dust roller 5 in preparation for the next time the dust roller 5 is switched.

[0026] As one implementation, the rotary mechanism 3 includes a transmission chain 31, a sprocket 32, a first motor (not shown in the figure), a connecting sleeve 33, and a connecting shaft 34. The sprocket 32 ​​supports both ends of the transmission chain 31, and the connecting shaft 34 is installed on the outside of the transmission chain 31 through the connecting sleeve 33. The dust rollers 5 are installed on both ends of the connecting shaft 34 through the mounting base 4. The first motor drives the sprocket 32 ​​to drive the mounting base 4 to move along the rotary path.

[0027] With the above configuration, the first motor drives the mounting base 4 through the sprocket 32 ​​and the transmission chain 31.

[0028] The transmission chain 31 of this application is elongated oval at both ends, supported by sprockets 32. The outer side of the transmission chain 31 is connected to the connecting shaft 34 through the connecting sleeve 33. The connecting shaft 34 is perpendicular to the movement direction of the polyester film and parallel to the dust-sticking roller 5. The length of the connecting shaft 34 is adapted to the length of the dust-sticking roller 5. The two ends of the connecting shaft 34 are fixedly connected to the mounting base 4. The end of the dust-sticking roller 5 is rotatably connected to the mounting base 4 to realize the connection between the transmission chain 31 and the dust-sticking roller 5. When the first motor drives the transmission chain 31 through the sprocket 32, the transmission chain 31 drives the mounting base 4 to move on the elongated oval rotation path through the connecting sleeve 33 and the connecting shaft 34.

[0029] As one implementation, the rotary mechanism 3 also includes guide rails 35 located on the left and right sides of the transmission chain 31. The guide rails 35 are provided with grooves, and the mounting base 4 is provided with two sliding shafts 36 that are adapted to the grooves. The sliding shafts 36 are slidably connected in the grooves.

[0030] The above settings improve the stability of mounting base 4 on the rotation path.

[0031] like Figure 2 Guide rails 35 are symmetrically arranged on the left and right sides of the conveyor chain. The guide rails 35 are elongated oval, making the slide groove an elongated oval closed loop structure, which is just compatible with the oval rotation path. When the mounting seat 4 moves under the drive of the transmission chain 31, the sliding shaft 36 slides along the slide groove. The guide rails 35 prevent the mounting seat 4 from moving up and down during movement. Each mounting seat 4 is provided with two sliding shafts 36. When the transmission chain 31 is stationary, the mounting seat 4 is more stable.

[0032] In one implementation, the mounting base 4 includes a base 41, a guide rod 42, a spring 43, and a connecting seat 44. The base 41 is fixedly connected to the end of the connecting shaft 34, and the sliding shaft 36 is fixedly connected to the base 41. The guide rod 42 is perpendicular to the rotation path, passes through the base 41, and is slidably connected to the base 41. The connecting seat 44 is located on the side of the base 41 away from the transmission chain 31 and is fixedly connected to the guide rod 42. The spring 43 is installed between the base 41 and the connecting seat 44, and the end of the dust roller 5 is rotatably connected to the connecting seat 44.

[0033] With the above settings, the dust-sticking roller 5 can float up and down, so that the dust-sticking roller 5 can stably contact the polyester film.

[0034] Specifically, under the action of the guide rod 42, the connecting seat 44 can stably approach or move away from the base 41. When the connecting seat 44 approaches the base 41, the spring 43 is compressed. When the connecting seat 44 moves away from the base 41, the spring 43 rebounds. The dust-adhesive roller 5 on the working position gently presses the polyester film downward under the action of the spring 43, so that the dust on the upper side of the polyester film can be stably adhered by the dust-adhesive roller 5, ensuring the dust removal effect.

[0035] As one implementation, the connecting seat 44 includes a fixed seat 441, a movable seat 442 and fasteners. The fixed seat 441 is fixedly connected to the guide rod 42. The fixed seat 441 is provided with a first semi-circular groove on the side away from the guide rod 42. The movable seat 442 is provided with a second semi-circular groove. The movable seat 442 is locked onto the fixed seat 441 by fasteners. The first semi-circular groove and the second semi-circular groove cover the end of the sticky roller 5.

[0036] The above settings facilitate the replacement of the adhesive roller 5.

[0037] When the sticky roller 5 needs to be replaced, after removing the fasteners, remove the movable seat 442 from the fixed seat 441. After the end of the sticky roller 5 is exposed, remove the sticky roller 5 from the fixed seat 441. Then, place the end of the new sticky roller 5 on the first semi-circular groove of the fixed seat 441. Then, lock the movable seat 442 back onto the fixed seat 441 with the fasteners. The second semi-circular groove and the first semi-circular groove cover the end of the sticky roller 5 to prevent the end of the sticky roller 5 from moving radially. A graphite layer or lubricating oil can be provided on the first semi-circular groove and the second semi-circular groove to reduce the rotational resistance of the sticky roller 5. A limit key can be fixedly connected to the outside of the fixed seat 441. After the limit key abuts against the end face of the sticky roller 5, it can prevent the sticky roller 5 from moving axially, thereby improving the stability of the sticky roller 5.

[0038] As one implementation method, the guide rail 35 is fixedly connected to the ground via the column 37.

[0039] As one implementation method, the dust removal device also includes a support belt 7, a support wheel 8, and a second motor (not shown in the figure). The support belt 7 supports the lower side of the polyester film, and the support wheel 8 supports both ends of the support belt 7 and is driven by the second motor.

[0040] With the above setup, the support belt 7 supports the polyester film, facilitating dust removal from one side.

[0041] The support belt 7 of this application is taut under the action of the support wheel 8. The upper side of the support belt 7 horizontally supports the polyester film. When the dust roller 5 moves downward and abuts against the polyester film, the polyester film will not sag. During dust removal, the second motor drives the support belt 7 to run. The support belt 7 and the polyester film move at the same speed, which prevents the polyester film from being worn due to relative friction between the polyester film and the support belt 7.

[0042] It should be understood that those skilled in the art can make improvements or modifications based on the above description, and all such improvements and modifications should fall within the protection scope of the appended claims.
