[0002] With the development of economy and the progress of science and technology, the market demand for optical films is growing, which not only promotes the expansion of optical film industry, but also drives the growth of related dust removal equipment market. In order to meet the market demand, enterprises need to continuously optimize production process and improve product quality, which includes the use of advanced dust removal technology. With the improvement of environmental protection awareness and the strengthening of relevant laws and regulations, the emission standards for waste gas and dust generated in industrial production process are becoming more and more stringent, which prompts optical film manufacturers to take effective waste gas treatment and dust removal measures to meet environmental protection requirements and reduce the impact on the environment. While pursuing economic benefits, society has put forward more environmental friendliness of industrial production. In order to meet high requirements, optical film manufacturers need to control the emission of dust and harmful gases in the production process and adopt advanced dust removal equipment and technology to achieve green production. The development of scientific film technology has promoted the demand for high-performance dust removal equipment. With the widespread application of optical films in optoelectronic display, new energy, LED lighting and other fields, the requirements for film quality are getting higher and higher, which requires the use of efficient dust removal equipment in the production process to ensure the quality and performance of the product. In the context of globalization, optical film companies are facing competition and cooperation in the international market. In order to maintain competitiveness in the international market, companies need to introduce and adopt internationally advanced dust removal technologies and equipment to improve product quality and production efficiency.

[0003] In the prior art, the optical film roll is fixed in the removal equipment with bolts, which makes the disassembly and installation steps cumbersome and time-consuming during the processing. The operator needs to make adjustments, which reduces the processing efficiency. The convenient disassembly and assembly design allows the optical film roll to be quickly removed and installed when replaced, reducing the replacement time and being more suitable for production lines. Utility Model Content

[0004] The utility model aims to solve the shortcomings in the prior art and proposes a dust removal device for optical film slitting.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: it comprises an equipment shell, a fixing device is fixed on the front end surface of the equipment shell, the fixing device comprises a fixed base, a limiting block is fixed on the upper end surface of the fixed base, a supporting block provided on the top of the fixed base is rotatably connected to the inner wall of the supporting bearing, a fixing bracket is fixed on the surface of the supporting bearing, a hand grip rod is threadedly connected to the inner wall of the fixed bracket, a limiting baffle is fixed on the front end surface of the hand grip rod, an arc groove is provided on the outer wall of the limiting block, in the prior art, the optical film roll is fixed in the removal equipment by bolts, which leads to cumbersome disassembly and installation steps, and the processing process is quite time-consuming, and the operator needs to make adjustments, which reduces the processing efficiency, and the convenient disassembly and assembly design allows the optical film roll to be quickly removed and installed when replaced, The replacement time is reduced and the product is more suitable for production lines. By adopting the installation of a new type of fixing device, when the user installs the optical film roll, he pushes the hand grip stick outward to drive the fixed bracket to move outward, so that the limit baffle moves along the front end inclined surface of the limit card block until it reaches the arc groove. At this time, push it outward again, and the fixed bracket drives the front end protrusion of the limit card block to rotate outward. At this time, the limit card block rotates, so that the arc-shaped teeth at the bottom of the limit card block are separated from the fixed base. At this time, the film roll can be taken out and replaced along the front end groove of the fixed base, and then the hand grip stick is pushed in the reverse direction until the limit baffle moves to the front end inclined surface of the limit card block to complete the fixation. At this time, when the limit card block is moved outward by external force, the force applied to the limit baffle is downward, which indirectly reinforces the limit card block, thereby reducing the time for replacing the film roll during processing and improving processing efficiency.

[0006] Preferably, support devices are fixed to the end faces of both sides of the device shell, and the support devices include support walls, support springs are fixed to the inner walls of the support walls, and a slider is fixed to the other end of the support spring, and the slider is slidably connected to the support wall, and a dust removal felt rod is rotatably connected to the inner wall of the slider, and a fixed block is fixed inside the support wall, and a support shaft rod is rotatably connected inside the fixed block. In the prior art, optical film rolls may be contaminated by dust particles in the air during the production process, and these dusts may adhere to the surface of the film, affecting the transparency and optical properties of the film, thereby reducing the quality of the product. At the same time, dust particles may cause scratches or other physical damages during the manufacturing process of the film roll, resulting in production defects, which not only affect the appearance of the product, but also affect its functions, such as reflectivity, light transmittance, etc. The utility model installs support devices on both sides of the device shell. When removing dust from the film roll, one end of the film roll is passed through the gap between the dust removal felt rod and the support shaft rod, and the dust removal felt rod is started to rotate. Due to the support springs at both ends, the film roll is clamped and dusted, thereby achieving rapid dust removal of the optical film roll.

[0007] Preferably, baffles are fixed to the end surfaces of both sides of the slider, so as to prevent the film roll from being dislocated and damaged when the staff uses the storage reel rod.

[0008] Preferably, baffles are fixed to both side end surfaces of the slider, so as to prevent the slider from falling off the supporting wall when moving.

[0009] Preferably, the support spring is a double-strand spring. Since the two strands of the double-strand spring are independent of each other, any problem with the other strand will not affect the use of the other strand, thereby increasing the stability and safety of the equipment.

[0010] Preferably, slide grooves are provided on both sides of the support wall, and the objects can be restricted to slide on a straight line or a curved path through the slide grooves, thereby ensuring that the slider moves according to a preset trajectory.

[0011] Preferably, a rubber sleeve is fixed on the surface of the grip stick, so that the staff can avoid slipping when using the grip stick, which makes the grip stick more comfortable and reduces hand fatigue.

[0012] Beneficial Effects

[0013] 1. In the prior art, the optical film roll is fixed in the removal device by bolts, which leads to cumbersome disassembly and installation steps, and takes a lot of time in the processing process. The operator needs to make adjustments, which reduces the processing efficiency. The convenient disassembly and assembly design allows the optical film roll to be quickly removed and installed when replaced, reducing the replacement time and being more suitable for the production line. By adopting the installation of a new fixing device, when the user installs the optical film roll, the hand grip stick is pushed outward to drive the fixed bracket to move outward, so that the limit baffle moves along the front end inclined surface of the limit card block until it reaches the arc groove. At this time, it is pushed outward again, and the fixed bracket drives the front end protrusion of the limit card block to rotate outward. At this time, the limit card block rotates, so that the arc-shaped card teeth at the bottom of the limit card block are separated from the fixed base. At this time, the film roll can be taken out and replaced along the front end groove of the fixed base, and then the hand grip stick is pushed in the reverse direction until the limit baffle moves to the front end inclined surface of the limit card block to complete the fixation. At this time, when the limit card block is moved outward by external force, the force applied to the limit baffle is downward, which indirectly reinforces the limit card block, thereby reducing the time for replacing the film roll during processing and improving processing efficiency.

[0014] 2. In the prior art, during the production process, the optical film roll will be contaminated by dust particles in the air. These dust particles will adhere to the surface of the film, affecting the transparency and optical properties of the film, thereby reducing the quality of the product. At the same time, dust particles will cause scratches or other physical damages during the manufacturing process of the film roll, leading to production defects. These defects not only affect the appearance of the product, but also affect its functions, such as reflectivity, transmittance, etc. The utility model installs support devices on both sides of the equipment casing. When removing dust from the film roll, one end of the film roll is passed through the gap between the dust removal felt rod and the support shaft rod, and the dust removal felt rod is started to rotate. Due to the support springs at both ends, the film roll is clamped to remove dust, thereby achieving rapid dust removal of the optical film roll. BRIEF DESCRIPTION OF THE DRAWINGS
