Description

Technical Field

[0001] This utility model relates to the field of PVC film cleaning technology, specifically to a cleaning device for PVC film printing. Background Technology

[0002] To prevent dust and other contaminants on the surface of PVC film from affecting its subsequent use, it is usually necessary to clean the PVC film before use. Currently, the traditional cleaning method is mostly water washing to remove dust. During the rinsing process, the dust carried by the water flow is easily redeposited on the film surface, affecting the cleaning effect. Some devices that use wiping structures (such as absorbent cotton) also pose a risk of debris residue. Moreover, traditional devices can only remove dust from one side of the PVC film, and the film needs to be manually flipped to complete the cleaning of both sides. This process not only increases the number of operation steps, but also easily contaminates the other side of the PVC film surface when flipping, leading to the risk of secondary pollution. In order to solve the above problems, this utility model provides a cleaning device for PVC film printing. Utility Model Content

[0003] To address the aforementioned technical shortcomings, the purpose of this utility model is to provide a cleaning device for PVC film printing. Through a bidirectional negative pressure suction design, it can simultaneously process contaminants on both sides of the film material, avoiding the need for flipping in traditional single-sided cleaning. It can also avoid residue problems generated during the cleaning process and improve the cleaning effect.

Under the torsion of the torsion spring, the suction frame presses against the PVC film.

[0011] Preferably, a roller is rotatably mounted on the side of the suction frame near the PVC film where the suction port is located.

[0012] Preferably, the frame has two support shafts rotatably mounted inside. The support shafts are located on the side of the corresponding suction frame in the pressing direction and on the side of the PVC film away from the suction frame, for supporting the PVC film.

[0013] Preferably, the lower side of the suction frame is tangent to the support shaft.

[0014] Preferably, a scraper is fixedly connected to the inner side of the suction frame, and the scraper abuts against the surface of the roller.

[0015] Preferably, the guiding component includes:

[0016] A drive shaft, which is rotatably mounted inside the frame and driven by a motor mounted on the frame;

[0017] Driven shaft, the driven shaft being installed inside the frame;

[0033] 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.

[0034] This utility model provides a cleaning device for PVC film printing, such as Figures 1 to 6 As shown.

[0035] Example 1:

[0036] A cleaning device for PVC film printing includes a frame 1. Inside the frame 1, there is a guide component and two cleaning components. The guide component guides the PVC film to be cleaned through the frame 1, and the cleaning components clean the surface of the PVC film as it passes through the frame 1. The two cleaning components are located on both sides of the PVC film, which can clean both sides of the PVC film, thereby improving the cleaning efficiency.

[0037] The cleaning component includes a suction frame 2, which is installed inside the frame 1. The suction frame 2 has a suction port on the side closest to the PVC film, and the other side is connected to an external negative pressure device through a connecting frame 3, so that the dust on the surface of the PVC film can be removed by negative pressure suction.

[0038] Both ends of the suction frame 2 are fixedly connected to the mounting shaft 5. The mounting shaft 5 is rotatably connected to the inner side of the frame 1, and a fixing plate 6 is fixedly connected to the mounting shaft 5. A torsion spring 7 is connected between the fixing plate 6 and the inner side wall of the frame 1. Under the torsion of the torsion spring 7, the suction frame 2 will press against the PVC film, so that the suction frame 2 can better remove the dust from the surface of the PVC film.

[0039] Example 2:

[0040] Based on Embodiment 1, to avoid scratches on the PVC film surface caused by hard contact between the suction frame 2 and the PVC film, a roller 8 is rotatably installed on the side of the suction frame 2 near the PVC film, so that the suction frame 2 and the PVC film become rolling contact. A support shaft 9 is provided on the side of the PVC film away from the suction frame 2. The support shaft 9 is rotatably installed inside the frame 1. The support shaft 9 can support the PVC film, thereby preventing deformation and damage to the PVC film due to the clamping force of the suction frame 2. At the same time, the setting of the support shaft 9 can cause the PVC film to bend when it passes around, so that the dust on the surface of the PVC film can be peeled off more easily. The lower side of the suction frame 2 is tangent to the support shaft 9. With the setting of the roller 8, the PVC film can pass smoothly between the suction frame 2 and the support shaft 9.

[0041] Inside the suction frame 2, a scraper 16 is fixedly connected. The scraper 16 presses against the roller 8 and can clean the roller 8 by scraping off the dust adhering to the roller 8. This prevents the roller 8 from rotating continuously, which would cause the dust adhering to it to re-adhere to the surface of the PVC film and affect the cleaning effect.

[0042] An inlet shaft 17 is also rotatably mounted inside the frame 1. The inlet shaft 17 is configured to allow the PVC film to enter the interior of the frame 1 at a specified height, thereby enabling the PVC film to bypass the first support shaft 9 it contacts at a specific angle (e.g., ...). Figure 4(as shown) Figure 4 The arrows in the diagram indicate the direction of movement of the PVC film.

[0043] Example 3:

[0044] The guiding assembly includes a drive shaft 10 and a driven shaft 12. The drive shaft 10 is driven by a motor 11 mounted on the frame 1. The motor 11 is electrically connected to an external power source via a cable. The start and stop of the motor 11 can be controlled by switching the control circuit on and off.

[0045] Both ends of the driven shaft 12 are rotatably mounted with sliders 13. The sliders 13 are slidably mounted in the grooves 14 provided on the frame 1. A spring 15 is connected between the groove wall of the groove 14 and the slider 13. One end of the spring 15 is fixedly connected to the groove wall of the groove 14, and the other end is fixedly connected to the slider 13. The spring 15 has a clamping force that makes the driven shaft 12 press against the drive shaft 10. Under the action of this clamping force, the driven shaft 12 will cooperate with the drive shaft 10 to clamp the PVC film. At this time, the drive shaft 10 rotates and can cooperate with the driven shaft 12 to guide the PVC film through the frame 1.

[0046] In order for the drive shaft 10 and driven shaft 12 to pull the PVC film more stably, rubber sleeves 4 are fixedly connected to the outer ring surfaces of the drive shaft 10 and driven shaft 12. This can increase the friction between the drive shaft 10 and driven shaft 12 and the PVC film, so that the drive shaft 10 and driven shaft 12 can pull the PVC film more stably.

[0047] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
