Description

Technical Field

[0001] This utility model relates to the field of cast film strip cleaning technology, and more specifically, to a residue cleaning device for cast film strips. Background Technology

[0002] Ceramic slurry casting uses a film tape as a carrier. After passing through different stages of drying ovens, the desired ceramic raw material is formed and adhered to the film tape. Finally, the film tape and raw material are separated by rollers and simultaneously wound up. Due to material properties and temperature fluctuations, some unmelted material may remain on the film tape, making it difficult to demold. During the winding process, the film tape will also collect the undemolded slurry and other material residues, forming hardened residues that can lead to defects such as blistering on the surface of subsequent products. Most film tapes are for single use, but the price of existing film tapes on the market is expensive.

[0003] Therefore, cleaning the membrane belt increases its lifespan, protects it, and saves costs. However, currently, membrane belt cleaning mostly relies on manual scrapers or manual rollers, which is inefficient and poses safety hazards. In addition, the membrane belt is large, requiring at least two people to clean it simultaneously, making the cleaning process difficult.

[0004] In view of the above, this application is hereby submitted. Utility Model Content

[0005] The technical problem this invention aims to solve is that cleaning film belts using manual scrapers or adhesive rollers is inefficient, difficult, and poses safety hazards. The purpose is to provide a residue cleaning device for cast film belts. The uncleaned film belt is first powerfully cleaned by an adsorption air knife cleaning device, and then adhesively cleaned by an adhesive roller device to avoid residue. This achieves two-stage cleaning of the film belt, improves cleaning efficiency, and ensures cleaning effect.

[0006] This utility model is achieved through the following technical solution:

[0007] This utility model provides a residue cleaning device for cast film tape, including an unwinding roller and a winding roller. The unwinding roller is used to rotate and release the film tape wound on it, and the winding roller is used to rotate and wind the film tape.

[0008] An adsorption air knife device and an adhesive roller device are sequentially arranged between the unwinding roller and the winding roller.

[0009] The adsorption air knife device is arranged between the viscous roller device and the unwinding roller and is located above the film belt, and is used to adsorb residues on the surface of the film belt by negative pressure.

[0010] The adhesive roller assembly includes a high-strength adhesive roller and a soft, weak adhesive roller arranged in parallel at the top and bottom.

[0011] The film strip passes between a rotating strong adhesive roller shaft and a soft weak adhesive roller shaft, the rotating strong adhesive roller shaft being used to adhere residue to the surface of the film strip.

[0012] This utility model's residue cleaning device modifies a traditional film winding machine by installing an adsorption air knife device. The uncleaned film belt is first powerfully cleaned by the adsorption air knife cleaning device, and then coarse and fine adhesive cleaning is performed by combining two different adhesive rollers in the adhesive roller device. In automatic cleaning mode, the film belt is cleaned in two stages, which greatly improves cleaning efficiency, ensures cleaning effect, and reduces cleaning difficulty compared to traditional manual cleaning of film belt.

[0013] In one specific embodiment, the adsorption air knife device includes an adsorption air knife, the bottom of which is provided with an adsorption port, and a scraper is provided at the edge of the adsorption port.

[0014] The compressed air pressure at the adsorption port of the air knife is limited to 0.20–0.80 MPa. Higher pressure results in faster airflow and stronger cleaning power, but also increases energy consumption. The airflow velocity at the adsorption port is limited to 30,000–50,000 m / s. Higher velocity results in greater impact force, suitable for stubborn pollutants. The width of the air knife is selected based on the membrane belt width. The vacuum generator's negative pressure is designed to be -20–80 kPa; higher negative pressure results in stronger adsorption capacity. The airflow rate at the adsorption port is designed to be 200–500 L / min, which must be matched to the airflow output of the air knife.

[0015] The adsorption air knife device also includes a control system, which includes a pressure regulating valve, a flow regulating valve, and a frequency converter to achieve dynamic adjustment of the air knife pressure and adsorption force. Its specific detailed structure can adopt existing conventional air knives, so it will not be described in detail here.

[0016] In one specific embodiment, the adsorption port of the adsorption air knife has a narrow slit structure, which facilitates airflow concentration and thus improves cleaning efficiency.

[0017] In one specific embodiment, the adsorption air knife is rotatably configured relative to the membrane belt to adjust the angle between the adsorption port and the membrane belt. Specifically, it can be set to an adjustable angle of 90° to adapt to different cleaning angle requirements.

[0018] In one specific embodiment, the adsorption air knife is mounted on the support frame via an L-shaped rotating rod. One end of the adsorption air knife is detachably connected to the L-shaped rotating rod via a thread, and the other end of the L-shaped rotating rod is rotatably connected to a rotating shaft, which is mounted on the support frame.

[0019] In one specific embodiment, the rotating shaft is connected to the support frame via a left-right translation bracket. The left-right translation bracket can translate left and right relative to the support frame along a horizontal direction perpendicular to the membrane belt. A front-back moving bracket is also installed on the rotating shaft. The front-back moving bracket is rotatably connected to the rotating shaft. The other end of the L-shaped rotating rod is slidably connected to the front-back moving bracket.

[0020] In one specific embodiment, the rotating strong adhesive roller shaft is connected to the support shaft via a connecting rod. The end of the connecting rod is rotatably connected to the support shaft. An operating lever is connected to the end of the connecting rod. By rotating the connecting rod, the rotating strong adhesive roller shaft can be driven to move upward away from the soft and weak adhesive roller shaft.

[0021] This invention, through its structure of a support frame, a translation bracket, and an L-shaped rotating rod, facilitates the adjustment of the position of the adsorption air knife device above the membrane belt.

[0022] In one specific embodiment, the rotating high-strength adhesive roller shaft requires higher adhesion and higher hardness to remove larger residues. Therefore, the substrate is made of silicone rubber, which not only has high viscoelasticity but also good chemical stability. In this invention, the specific parameters of the rotating high-strength adhesive roller shaft can be as follows: hardness 50-90A, adhesion force 210 N / cm. 2 (Adjusted according to contaminants), abrasion resistance <50mm 3 (1kg load, 1000 rpm), temperature range -40℃ to 70℃, resilience ≥80% (ensuring multiple cycles of use), surface roughness 110 microns (rough surface enhances adhesion).

[0023] In one specific embodiment, the soft, slightly sticky roller shaft requires lower hardness and moderate viscosity for fine cleaning to avoid residue; the substrate is selected as low-hardness silicone with good flexibility (elongation > 500%), and the substrate can also be selectively treated with antistatic agents. In this invention, the specific parameters of the soft, slightly sticky roller shaft can be as follows: hardness 10-40A, adhesion 0.11-0.5 N / cm. 2 (Adjusted according to pollutants), compression set ≤20%.

[0024] In one specific embodiment, the rotating high-strength adhesive roller is used for coarse cleaning of larger residues, while the soft, weak adhesive roller is used for fine cleaning to adsorb residual small residues. The rotating high-strength adhesive roller rotates at a low speed (180 rpm), while the soft, weak adhesive roller rotates at a high speed (360 rpm). This speed ratio can improve cleaning efficiency.

[0025] In one specific embodiment, a traction roller assembly is provided between the unwinding roller and the adsorption air knife device, and between the winding roller and the adhesive roller device. The traction roller assembly is used to adjust the tilt angle of the film strip on both sides of the adhesive roller device. Specifically, the film strip can be tilted at 45°.

[0026] Compared with the prior art, this utility model has the following advantages and beneficial effects:

[0027] 1. The present invention provides a residue cleaning device for cast film tape. By modifying the traditional film winding machine and installing an adsorption air knife device, the uncleaned film tape is first cleaned by the adsorption air knife cleaning device, and then coarse and fine adhesive cleaning is carried out by the combination design of two different adhesive rollers in the adhesive roller device. The two-stage cleaning of the film tape is realized in the automatic cleaning mode, which greatly improves the cleaning efficiency, ensures the cleaning effect, and reduces the cleaning difficulty compared with the traditional manual cleaning of film tape.
