In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0020] It should be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of the present invention. The drawings only show the components related to the present invention and are not drawn according to the actual number, shape and size of the components. In actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.

[0021] In the following description, numerous details are explored to provide a more thorough explanation of embodiments of the present invention. However, it will be apparent to those skilled in the art that embodiments of the present invention may be practiced without these specific details. In other embodiments, well-known structures and devices are shown in block diagram form rather than in detail to avoid obscuring embodiments of the present invention.

[0022] like Figure 1 - Figure 6 As shown, this utility model provides a film feeding device.

[0023] In an exemplary embodiment, the film feeding device includes a base, a support plate, and a film feeding mechanism. Along the film's travel direction, a coating mechanism and a scraping mechanism are sequentially arranged on the support plate. The coating mechanism includes a fixed frame and a feeding hopper. The fixed frame is equipped with a baffle plate assembly, which includes multiple pressure rollers located between the feeding hopper and the scraping mechanism. The scraping mechanism includes a support frame and a main shaft rotatably mounted on the support frame, with scraping blocks mounted on the main shaft.

[0024] In this embodiment, the coating mechanism and scraping mechanism enable automatic coating of the film with shielding material. The scraping mechanism also ensures that the thickness of the shielding material on the film is fixed, improving the uniformity of the coating on the antistatic film. Furthermore, no manual coating is required when applying the antistatic material, and the baffle prevents the antistatic material from overflowing, reducing costs and improving the cleanliness of the entire coating area.

[0025] For example, in this embodiment, the feeding mechanism includes a feeding roller disposed on the base and a guide roller disposed at the front of the support plate. The feeding roller is a roller tube with a tensioning function, which can fix the film. The guide roller is used to turn the film. After the film roll is fixed on the feeding roller, the end of the film is pulled out and wrapped around the guide roller to be parallel to the support plate and in contact with the support plate.

[0026] For example, in this embodiment, the fixing frame spans across the support plate and has a gate-shaped structure.

[0027] For example, in this embodiment, there are multiple pressure rollers. By using multiple pressure rollers to roll the shielding material, the uniformity of the shielding material on the film can be further improved.

[0028] It is worth noting that in this embodiment, the bottom of the feeding barrel is provided with multiple discharge holes, which are arranged in a rectangular or circular array. A pressurizing mechanism is provided inside the feeding barrel. After the coating is started, the pressurizing mechanism pressurizes the shielding material inside the feeding barrel. The shielding material is discharged at a constant speed through the discharge holes of the feeding barrel. The shielding material falls from the discharge holes onto the film material and is flattened by the pressure roller and evenly spread on the film.

[0029] It should also be noted that the shielding material in this embodiment is a paste, which has a certain viscosity and can adhere to the film.

[0030] In one exemplary embodiment, a drive cylinder is provided on the fixing frame, and the output end of the drive cylinder passes through a fixing plate provided on the fixing frame. The feed hopper is disposed on the fixing plate, and the drive cylinder is used to drive the feed hopper to move closer to or away from the film.

[0031] In this embodiment, the fixed plate can move vertically by means of a driving cylinder, thereby moving the baffle assembly closer to or away from the film and thus achieving the material blocking function.

[0032] For example, in this embodiment, there are two driving cylinders, symmetrically arranged on the fixed frame, to provide a stable driving force for the fixed plate. In a specific embodiment, the driving cylinders are installed at the front of the fixed frame so that the baffle assembly can stop the material.

[0033] An exemplary baffle assembly includes a first baffle, a second baffle, and a third baffle. The first baffle is located on both sides of the fixed plate in the width direction. The second baffle is located at the bottom of the first baffle and contacts the film. The third baffle is disposed on the side of the first baffle near the scraping mechanism. In this embodiment, the first baffle mainly serves a supporting function and is used to mount the pressure roller and the second baffle. The pressure roller is rotatably mounted on the first baffle. The second baffle is mounted at the bottom of the first baffle and can be made of rubber. Its bottom can contact the film to avoid scratching the film. The third baffle can prevent the shielding material after scraping by the scraping mechanism from accumulating between the scraping mechanism and the coating mechanism and overflowing from both sides. Together with the partition plate on the support plate, it can ensure that the shielding material is always on the film and will not overflow.

[0034] It is worth noting that the descent height of the fixed plate driven by the drive cylinder is set according to the specific requirements of the antistatic film. Different antistatic films have different shielding material thicknesses, and the descent height of the pressure roller is also different. The distance between the bottom of the pressure roller and the film is the same as the required shielding material thickness.

[0035] It should also be noted that in this embodiment, the height of the pressure roller in the vertical direction is moderately lower than the outlet end of the discharge hole, and the width of the pressure roller for pressing the material is moderately greater than the required width of the shielding material.

[0036] In an exemplary embodiment, the scraping mechanism further includes a first adjustment component disposed on the left and right sides of the support plate. The first adjustment component includes a first adjustment cylinder and a first slider. The first adjustment cylinder passes through the support frame and is provided with the first slider. The first slider is slidably connected to the support frame. The main shaft is rotatably connected between the sliders. The main shaft is provided with a mounting block. The scraping block is detachably connected to the scraping block. One end of the main shaft is provided with a drive rod for driving the main shaft to rotate.

[0037] In this embodiment, the scraping mechanism can control the thickness of the shielding material on the film, thereby improving the uniformity of the shielding material. The first adjustment component can indirectly adjust the height of the scraping block, and the distance between the scraping part and the film can be adjusted during scraping to determine the thickness of the shielding material.

[0038] For example, in this embodiment, when the first adjusting cylinder drives the first slider to move up and down, the first slider moves under the guidance of the support frame.

[0039] For example, in this embodiment, one end of the main shaft is provided with an adjustment motor, wherein the adjustment motor is a servo motor, and the angle at which the adjustment motor drives the scraper block to rotate corresponds to the corresponding height, which is stored in the control system. The adjustment motor is controlled by the control system, and when the required thickness of the shielding material is input, the scraper block is driven to rotate at the corresponding angle.

[0040] It is worth noting that in this embodiment, the scraping part of the scraping block is an arc-shaped part, and the scraped shielding material is located in the area formed between the scraping block, the baffle assembly and the partition plate.

[0041] In one exemplary embodiment, the film feeding device further includes a traction mechanism disposed on the side of the scraping mechanism away from the coating mechanism, and the traction mechanism is used to drive the film to move.

[0042] In this embodiment, the traction mechanism provides driving force for the transport of the film.

[0043] For example, the traction mechanism includes a driving wheel and a driven wheel. The driving wheel is mounted on a base, and the film is located between the driving wheel and the driven wheel. The gap between the driving wheel and the driven wheel is smaller than the thickness of the film and is used to drive the film to move. Simultaneously, the traction mechanism also includes second adjustment components mounted on the left and right sides of a support plate. The second adjustment components include a traction frame and a second slider. A second adjustment cylinder is mounted on the traction frame, and the output end of the second adjustment cylinder passes through the traction frame and connects to the second slider. The second slider is slidably connected to the traction frame, and a traction shaft is provided between the second sliders. The driven wheel is mounted on the traction shaft. In a specific embodiment, the driving wheel is fixed to the base by a driving rod. A drive motor is provided on one side of the base, and the output end of the drive motor is coaxially connected to the driving wheel to transmit power. Since the gap between the driving wheel and the driven wheel is smaller than the thickness of the film, the film sandwiched between the driving wheel and the driven wheel is transported to the rear, achieving film driving. Furthermore, in this embodiment, the height of the driven wheel can be adjusted by the second adjustment components, allowing the gap between the driven wheel and the driving wheel to be changed to accommodate films of different sizes.

[0044] In an exemplary embodiment, the present invention further includes a measuring mechanism, which includes a fixed rod, a meter counter, and a detection wheel. The fixed rod is mounted on a support plate, the meter counter is detachably connected to the fixed rod, and the detection wheel is rotatably connected to the input end of the meter counter. The detection wheel abuts against the driven wheel and is used to drive the wheel to rotate via the driven wheel.

[0045] In this embodiment, the processing length of the film can be detected by the set measuring mechanism. Specifically, since the driven wheel rotates and drives the detection wheel to rotate, the number of rotations of the detection wheel is transmitted to the meter counter. The meter counter can calculate the length of the film passing through the traction mechanism based on the size of the driven wheel and the number of rotations, and then feed the data back to the control system and output it.

[0046] In summary, this utility model, through its coating mechanism and scraping mechanism, can automatically coat the film with shielding material. At the same time, the scraping mechanism can fix the thickness of the shielding material on the film, thereby improving the uniformity of the coating on the antistatic film, reducing costs, and improving the cleanliness of the entire coating area.

[0047] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
