Technical Field
[0001] This utility model relates to a film feeding machine, and more particularly to a dust-removable film feeding machine. Background Technology
[0002] Film feeders are widely used in various production and packaging industries, mainly for unrolling rolls of film material and conveying them to subsequent processing equipment.
[0003] Traditional film feeders typically include unwinding, guiding, and tensioning devices, primarily designed to ensure the flatness and stability of the film during transport. However, with the continuous development of industrial production, the requirements for film quality and production efficiency are increasing. During unwinding and transport, the film surface easily absorbs dust and impurities from the air. These dust and impurities not only affect the surface quality of the film but can also cause equipment malfunctions in subsequent processing, impacting production efficiency and product quality. Existing film feeders can no longer fully meet processing needs in terms of dust removal. Utility Model Content
[0004] To overcome the problem that dust and impurities easily adsorbed from the air on the film surface during unwinding and conveying, which not only affects the surface quality of the film but also causes equipment failure in subsequent processing, affecting production efficiency and product quality, the existing film feeders are no longer sufficient to meet processing requirements in terms of dust removal. The aim is to provide a dust-removable film feeder to solve the above problems.
[0005] The technical solution is as follows: A dust-removable film feeder includes a frame, side plates, a control panel, a mounting base, an unwinding roller, a transfer roller, a feed roller, an output roller, an upper box plate, a dust collector, a dust collection box, a plasma fan, an air blowing box, a connecting plate, and a lower box plate. Side plates are horizontally arranged on both the front and rear sides of the upper part of the frame, with the two side plates symmetrically arranged. A control panel is located on the front side plate, and a mounting base is fixedly located on the rear side plate. An unwinding roller is rotatably mounted on one side of the upper part of the mounting base for film roll installation and unwinding. Two feed rollers are mounted at the front of the mounting base, one of which is connected to a power component that drives the feed roller to rotate. There is a feed interval between the two feed rollers. A feed roller is rotatably mounted on the right side of the side plate, and two output rollers are located on the left side of the side plate, one of which is connected to a power component. There is an output interval between the two output rollers. When unwinding the film, one end of the film roll is pulled out on the unwinding roller and passed downward into the material transfer interval between the material transfer rollers. After the film is wrapped around the right side of the feed roller, the end of the film is passed out between the discharge rollers to the left. There are connecting plates on the front and rear sides of the left side plate. There is an upper box plate between the upper part of the connecting plates and a lower box plate between the lower part of the connecting plates. The upper box plate and the lower box plate are symmetrically arranged between the connecting plates. There is a dust collector on the rear side of the top of the upper box plate and a dust collection box on the rear side plate. The dust collection box has several dust collection slots. The dust collector is connected to the dust collection box through an air duct. There is a plasma fan at the front of the upper box plate and an air blowing box is installed on the front side plate. The plasma fan is connected to the air blowing box through an air duct. The air blowing box and the dust collection box are arranged opposite each other. When the film is guided from the feed roller to the discharge roller, it will pass between the upper box plate and the lower box plate and pass through the area between the air blowing box and the dust collection box.
[0006] Furthermore, it also includes a film transfer roller, with film transfer rollers installed on both the upper and lower boxes to assist in film transfer.
[0007] Furthermore, it also includes a fixed frame, a feeding roller, and a taking-up roller. The fixed frame is located on the front side of the mounting base and is arranged around the feeding roller. The lower part of the fixed frame has a film-passing notch, which is directly below the feeding interval of the two feeding rollers. Two feeding rollers are vertically arranged on the lower rear side of the fixed frame. The feeding rollers are used to install the wiping cloth master roll. The two feeding rollers are distributed on the left and right sides near the rear of the film-passing notch. Two taking-up rollers are vertically arranged on the lower front side of the fixed frame. The taking-up rollers are used to roll up the wiping cloth. The two taking-up rollers are distributed on the left and right sides near the front of the film-passing notch. Both the feeding roller and the taking-up roller are equipped with a rotary drive component.
[0008] Furthermore, it also includes guide rails, sliding frames, transmission components, and pressure plates. Two guide rails are installed on both the left and right sides of the membrane notch on the fixed frame. Sliding frames are slidably installed between the two guide rails on the same side. The two sliding frames are symmetrically arranged, and each sliding frame is equipped with a pressure plate. A transmission component is provided at the rear of the fixed frame. The transmission component consists of a drive motor and a double-acting screw. The double-acting screw has two threads in opposite directions. The rear parts of the two sliding frames are screwed into one thread of the double-acting screw, and the transmission component drives the two sliding frames to move in opposite directions in the left and right directions.
[0009] Furthermore, it also includes an optical track and a sensor. An optical track is provided on the upper part of the mounting base away from the unwinding roller. The optical track is arranged in the same direction as the unwinding roller. A sensor is provided on the optical track in a sliding and rotating manner.
[0010] Furthermore, it also includes a feeding roller and an air blowing pipe. Two feeding rollers are arranged in the right part of the connecting plate. The arrangement direction of the two feeding rollers is the same as that of the two discharge rollers. There is a feeding interval between the feeding rollers. One of the feeding rollers is equipped with a power component. After the film is transmitted from the feed roller, it will first pass through the feeding interval between the feeding rollers. An air blowing pipe is provided in the lower box plate. The air blowing pipe is equipped with several air outlets. The air outlets of the air outlets all face upward. When the film passes between the upper box plate and the lower box plate, the air blown out of the air outlets will impact the film.
[0011] The beneficial effects of this utility model are as follows:
[0012] 1. This utility model establishes a relatively enclosed space through upper and lower boxes during the film unwinding and feeding process. A dust collector and a plasma fan are installed along the film transport path within this space. The dust collector removes dust and fine particles from the film surface using strong suction, while the plasma fan generates plasma to neutralize the static electricity on the film surface, preventing dust from re-adhering. This facilitates the smooth progress of subsequent processes, such as coating, printing, and lamination, ensuring the stability and reliability of the entire production line.
[0013] 2. This utility model provides a wiping cloth below the transfer roller that can wipe both sides of the film surface. The cloth wipes the surface of the film as it is transferred, and as the film is transferred, it continuously and gently wipes the surface of the film to remove various contaminants attached to it, thereby improving the cleanliness of the film.
[0014] 3. This utility model uses a take-up roller and a release roller to install the cloth roll at the wiping station. After the wiping cloth in contact with the film has been used for a period of time, a clean wiping cloth is conveyed out through the cooperation of the take-up roller and the release roller, which avoids secondary contamination of the film caused by the contamination of the wiping cloth. By automatically replacing the clean wiping cloth, the frequency of manual intervention is reduced, and the production efficiency and automation level are improved.
[0015] 4. This utility model uses an air blowing device to cause the film transmitted between the upper and lower chambers to vibrate at a certain frequency, which helps to shake off dust and fine particles on the surface of the film to a certain extent, further optimizing the dust removal effect on the film.

Detailed Implementation
[0021] 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.
[0022] Example 1: A dust-removable film feeder, such as... Figure 1-4As shown, the machine includes a frame 1. Side plates 2 are horizontally arranged on both the front and rear sides of the upper part of the frame 1, and the two side plates 2 are symmetrically arranged. A control panel 3 is provided on the front side plate 2 for easy equipment control and parameter setting by the operator. A mounting base 4 is fixedly installed on the rear side plate 2. A roll unwinding roller 41 is rotatably mounted on one side of the upper part of the mounting base 4 for mounting and unwinding the film roll. Two transfer rollers 42 are mounted on the front of the mounting base 4. One of the transfer rollers 42 is connected to a power component, which drives the transfer roller 42 to rotate, ensuring smooth film transmission. A transfer interval exists between the two transfer rollers 42 to provide sufficient space for smooth film transmission. A guide roller 43 is rotatably mounted on the right side of the side plate 2 to guide the film into subsequent processes. Two discharge rollers 44 are located on the left side of the side plate 2. One of the discharge rollers 44 is connected to a power component. A discharge interval exists between the two discharge rollers 44 to ensure smooth film output from the equipment.
[0023] When unwinding the film, pull one end of the film roll out on the unwinding roller 41 and pass it downward into the material transfer interval between the material transfer rollers 42. After the film is wrapped around the right side of the feed roller 43, the end of the film is passed out between the discharge rollers 44 to the left.
[0024] Connecting plates 53 are provided on both the front and rear sides of the left side plate 2. An upper box plate 5 is provided between the upper parts of the connecting plates 53, and a lower box plate 6 is provided between the lower parts of the connecting plates 53. The upper box plate 5 and the lower box plate 6 are symmetrically arranged between the connecting plates 53, forming a relatively enclosed space, which helps to improve the dust removal effect. A dust collector 51 is provided on the rear side of the upper box plate 5, which removes dust and fine particles from the surface of the film through strong suction. A dust collection box 511 is provided on the rear side plate 2. The dust collection box 511 has several dust collection slots. The dust collector 51 is connected to and communicates with the dust collection box 511 through an air duct. The design of 1 increases the dust collection area and improves the dust collection efficiency. The front of the upper box plate 5 is equipped with a plasma fan 52, which generates plasma to neutralize the static electricity on the film surface and prevent dust from being re-adsorbed. An air blowing box 521 is installed on the front side plate 2. The plasma fan 52 is connected to the air blowing box 521 through an air duct. The air blowing box 521 and the dust collection box 511 are arranged opposite to each other. When the film is guided from the feed roller 43 to the discharge roller 44, it will pass between the upper box plate 5 and the lower box plate 6 and pass through the area between the air blowing box 521 and the dust collection box 511 to ensure that the film surface is thoroughly cleaned.
[0025] Among them, such as Figure 3 As shown, both the upper box plate 5 and the lower box plate 6 are equipped with film-passing rollers 7, which are used to assist in the transmission of the film, reduce the friction of the film during the transmission process, and ensure the flatness and stability of the film.
[0026] Example 2: Based on Example 1, such as Figure 4As shown, it also includes a fixed frame 8, a feeding roller 81, and a receiving roller 82. The fixed frame 8 is located on the front side of the mounting base 4, surrounding the feed roller 42 to form a semi-enclosed space to protect the internal structure and reduce the impact of the external environment on the cleaning process. A film-passing notch is opened at the bottom of the fixed frame 8, directly below the material transfer interval between the two feed rollers 42. This design allows the film to smoothly pass through the material transfer interval between the feed rollers 42 and exit through the fixed frame 8 for further cleaning. Two cloth-releasing rollers 81 are vertically arranged on the lower rear side of the fixed frame 8. The cloth-releasing rollers 81 are used to install the wiping cloth master roll. The two cloth-releasing rollers 81 are distributed on the left and right sides near the rear of the film-passing notch. The cloth-releasing rollers 81 are rotated by a rotary drive to release the clean wiping cloth. Two cloth-receiving rollers 82 are vertically arranged on the lower front side of the fixed frame 8. The cloth-receiving rollers 82 are used to rewind the wiping cloth. The two cloth-receiving rollers 82 are distributed on the left and right sides near the front of the film-passing notch. They are also equipped with a rotary drive to ensure that the used wiping cloth can be rewound in time to keep the working area clean.
[0027] In actual operation, when the film passes through the material transfer interval between the transfer rollers 42, it passes through the film passage notch of the fixed frame 8. At this time, the clean wiping cloth on the unloading roller 81 is released and closely adheres to the film surface, wiping the film as it moves to remove any tiny particles and stains that may remain on the film surface. At the same time, the take-up roller 82, through the action of the rotation drive, can continuously rewind the used wiping cloth. During the use of the wiping cloth, the unloading and rewinding work is performed intermittently to ensure that the passing film can come into contact with a relatively clean wiping cloth, thereby achieving a continuous and efficient cleaning effect. This design not only improves the cleanliness of the film but also simplifies the operation process, reduces the need for manual intervention, and improves production efficiency. In addition, the fixed wiping cloth path and rewinding mechanism also reduce the waste of wiping cloth, lower production costs, and enhance the economic and environmental performance of the equipment. In short, by adding the fixed frame 8, the unloading roller 81, and the take-up roller 82, the function of the film feeder is further optimized, making it more automated and convenient while ensuring efficient cleaning.
[0028] Among them, such as Figure 4As shown, two guide rails 83 are installed on both the left and right sides of the film-passing notch on the fixed frame 8. Sliding frames 84 are slidably mounted between the two guide rails 83 on the same side. The two sliding frames 84 are symmetrically arranged, and each sliding frame 84 is equipped with a pressure plate 86. The pressure plate 86 is used to press the wiping cloth tightly, ensuring close contact between the wiping cloth and the film surface, thus improving the cleaning effect. A transmission component 85 is located at the rear of the fixed frame 8. The transmission component 85 consists of a drive motor and a bidirectional lead screw. The bidirectional lead screw has two threads in opposite directions. The rear parts of the two sliding frames 84 are respectively screwed onto one thread of the bidirectional lead screw. The drive motor of the transmission component 85 drives the bidirectional lead screw to rotate, thereby causing the two sliding frames 84 to move in opposite directions in the left and right directions. This design allows for precise adjustment of the contact position and force between the wiping cloth and both sides of the film according to the film thickness and cleaning requirements, ensuring the uniformity and effectiveness of the cleaning process.
[0029] Specifically, when the film passes through the film-passing notch of the fixed frame 8, the pressure plates 86 on the two sliding frames 84 move inward or outward synchronously according to the rotation direction and speed of the bidirectional screw, adjusting the contact pressure between the pressure plates 86 and the film. By precisely controlling the position and pressure of the pressure plates 86, not only can sufficient contact between the wiping cloth and the film surface be ensured, but also damage or deformation of the film due to excessive pressure can be avoided. In addition, this dynamic adjustment mechanism can quickly switch between films of different thicknesses and materials, improving the adaptability and flexibility of the equipment. Overall, by adding the guide rail 83, sliding frame 84, transmission component 85 and pressure plate 86, this embodiment not only further improves the cleaning effect of the film, but also enhances the intelligence and automation level of the equipment. It also includes a light track 9 and a sensor 91. The light track 9 is provided on the side of the mounting base 4 away from the unwinding roller 41. The light track 9 is arranged in the same direction as the unwinding roller 41. The sensor 91 is slidably and rotatably mounted on the light track 9.
[0030] In a preferred embodiment, the device further includes a feeding roller 10 and an air blowing pipe 101. Two feeding rollers 10 are arranged between the right sides of the connecting plate 53. The arrangement direction of the two feeding rollers 10 is consistent with the arrangement direction of the two discharge rollers 44. There is a feeding interval between the feeding rollers 10. One of the feeding rollers 10 is equipped with a power component. The power component drives the feeding roller 10 to rotate, ensuring that the film can be smoothly transferred from the feed roller 43 to the discharge roller 44. After the film is transferred from the feed roller 43, it will first pass through the feeding interval between the feeding rollers 10 and then continue to be transferred forward.
[0031] The lower box plate 6 is equipped with an air blowing pipe 101, which has several air outlets. The air outlets of the air outlets all face upward. When the film passes between the upper box plate 5 and the lower box plate 6, the air blown out of the air outlets will impact the film. By adjusting the speed of the power components of the feeding roller 10 and the discharge roller 44, the tension of a section of film in the area between the upper box plate 5 and the lower box plate 6 can be adjusted, so that the blown air can better control the shaking frequency of the film. By generating a certain frequency of shaking of the film, dust and fine particles on the surface of the film are shaken off to a certain extent, further optimizing the dust removal effect on the film.
[0032] The above description is only a preferred embodiment of the present utility model and is 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 should be included within the protection scope of the present utility model.
