[0029] Figure 2 A schematic diagram of the structure of a filter element provided in an embodiment. DETAILED DESCRIPTION

[0030] The utility model proposes an automatic cleaning packaging paper production device, including a frame, a paper storage roller, a paper guide roller, a paper cleaning brush, a filter element, a paper pressing roller, a driving roller and a driving motor. The frame is composed of a column and a base, which is used to support and fix various components; the paper storage roller is used to store the produced packaging paper roll; the paper guide roller is used to guide the paper to ensure smooth paper feeding; the paper cleaning brush adopts soft bristles to deeply clean the surface of the paper; the filter element is used to collect dust cleaned by the cleaning brush; the paper pressing roller and the driving roller drive the paper to be transported forward by squeezing and pulling; the driving motor provides power to each roller shaft through belt transmission.

[0031] Working principle: The packaging paper to be cleaned is introduced by the paper guide roller, and is deeply cleaned by the paper cleaning brush to remove surface dust and impurities. The cleaned dust is collected by the filter element. The cleaned paper is driven by the paper pressing roller and the driving roller, and is smoothly transported forward, and finally rolled up on the paper storage roller, completing the automatic cleaning process.

[0032] The utility model proposes an automatic cleaning packaging paper production device, such as Figure 1 , which mainly consists of the following parts:

[0033] Paper storage roller 1: used to store and rewind the finished packaging paper. It is cylindrical, with journals at both ends connected to bearings. It is installed on the frame through bearings.

[0034] The paper storage roller 1 is made of high-strength aluminum alloy or stainless steel, and the surface is anodized or polished to improve corrosion resistance and wear resistance. In addition, it can be customized according to production needs, and the diameter is usually 200-500mm and the length is 1000-3000mm.

[0035] It should be noted that the paper storage roller 1 needs to be surface treated: the surface is processed into multiple annular grooves for fixing the paper to prevent slipping. In addition, it uses heavy-load ball bearings or self-aligning ball bearings to ensure stability under high-speed rotation and heavy-load conditions.

[0036] Roller bearing seat 2: used to support the paper storage roller shaft so that it can rotate smoothly. It is in the shape of a rectangular parallelepiped with a bearing inside and a mounting flange outside. It is fixed to the frame (No. 8) by bolts to provide support for the paper storage roller.

[0037] The roller bearing seat 2 is made of cast iron or aluminum alloy material, which has good strength and rigidity. It selects suitable ball bearings, roller bearings or sliding bearings according to the roller size and load. In addition, it adopts labyrinth seals or contact seals to prevent dust and impurities from entering the bearings. In addition, a grease box or oil cup is set to regularly add lubricant to extend the bearing life.

[0038] Paper guide roller 3: used to guide the paper into the cleaning part to ensure the paper moves smoothly. It is a slender cylindrical roller with a smooth surface. It is installed on the frame through a bearing seat and is located between the paper storage roller and the cleaning brush.

[0039] The paper guide roller 3 is made of aluminum alloy or stainless steel, and its surface is hard anodized to improve wear resistance. Its surface is processed into spiral grooves or rubber coating to increase friction and prevent paper from slipping.

[0040] Brush roller 4: used to clean the paper surface and remove dust and impurities. It is cylindrical and covered with soft bristles. It is installed on the frame through the bearing and used in conjunction with the filter element.

[0041] Paper cleaning brush 5: used to clean the paper surface, remove dust and impurities, cylindrical, with soft bristles on the surface, installed on the frame through the bearing, used in conjunction with the filter element.

[0042] The paper cleaning brush 5 is made of materials such as nylon, horsetail hair or stainless steel wire, taking into account flexibility and cleaning performance. The bristle density (usually 1000-3000 pieces / square inch) and length (10-30mm) are optimized according to the paper type and degree of contamination. The bristle angle is usually set to 5-15°, which can effectively clean while avoiding damage to the paper.

[0043] The cleaning brush is driven by an independent motor, with a rotation speed of 1000-3000rpm, which improves cleaning efficiency. In addition, an eccentric block or cam is designed on the cleaning brush shaft to generate slight vibration, which helps to clean the paper texture.

[0044] Filter element 6: used to collect dust and impurities cleaned by the cleaning brush. It is cylindrical and has multiple layers of filter material inside. It is installed under the cleaning brush and fixed by buckles or bolts.

[0045] like Figure 2 As shown, the filter element 6 adopts a multi-layer composite structure, including a primary filter screen, a middle HEPA filter membrane and a final activated carbon adsorption layer. The primary filter screen adopts a stainless steel woven mesh to filter large particles; the middle HEPA filter membrane adopts a hot melt sprayed polypropylene fiber membrane to filter particles larger than 0.3 microns; the final activated carbon adsorption layer is used to absorb organic matter and odor.

[0046] In addition, the filter element has a built-in differential pressure sensor and control chip, which can monitor the blockage degree of each layer of filter material in real time. When a layer of filter material reaches the set differential pressure threshold, the control chip will automatically switch the air flow path, temporarily bypass the layer of filter material, extend its service life, and promptly remind you to replace it. At the same time, different layers of filter material can be combined and matched according to actual production needs to achieve performance and cost optimization. This adaptive multi-layer composite filter element is suitable for production environments with high cleanliness requirements and complex and changeable dust composition.

[0047] In one embodiment, the filter element is packaged in a detachable filter element box (not shown in the figure). Traditional filter element replacement usually requires shutdown and disassembly, which is time-consuming and labor-intensive. In view of this pain point, the utility model designs a modular replaceable filter element box.

[0048] The filter cartridge box adopts a drawer-type structure and is equipped with multiple parallel filter cartridge modules. Each module can be disassembled and replaced independently. At the inlet and outlet of the filter cartridge box, there are electric-controlled pneumatic valves and bypass pipelines. When a filter cartridge module reaches the replacement cycle, the system will automatically close the inlet and outlet valves of the module, switch the airflow to the bypass pipeline, and issue a replacement reminder at the same time.

[0049] The operator only needs to pull out the drawer and quickly replace the filter module. The whole process does not require downtime and will not affect the operation of the equipment. The filter module adopts a standardized design, which is convenient for mass production and inventory management. At the same time, the filter box is equipped with an electronic chip that can record the use time and replacement record of each filter module, which is convenient for preventive maintenance. This modular replaceable filter box is suitable for continuous production occasions where frequent downtime is not allowed and the filter element needs to be replaced quickly.

[0050] The frame columns 7 vertically support the frame and are square columns.

[0051] The frame base 8 is used to support and fix the entire device and is a rectangular parallelepiped.

[0052] Among them, the frame column 7 is designed according to the following specifications and requirements:

[0053] Material selection: Use high-strength carbon steel or stainless steel materials, such as Q235, 304 stainless steel, etc. to ensure sufficient strength and rigidity.

[0054] Section shape: square or rectangular hollow section, taking into account both strength and lightness. Common specifications include 50×50×3mm, 80×40×4mm, etc.

[0055] Connection method: The column and the base are connected by welding or bolts to ensure reliable connection. Full penetration welding should be used during welding, and non-destructive testing should be performed.

[0056] Surface treatment: The surface of the column is treated with anti-corrosion treatment such as plastic spraying, electrophoresis or hot-dip galvanizing to improve corrosion resistance and aesthetics.

[0057] Height adjustment: Adjustable feet or spacers are designed at the bottom of the column to facilitate horizontal adjustment and installation of the rack.

[0058] The rack base 8 is designed according to the following specifications and requirements:

[0059] Material selection: cast iron, welded steel plate or aluminum alloy materials, with good strength and stability.

[0060] Section design: According to the frame stress analysis, the base section size and reinforcement arrangement are reasonably designed to ensure sufficient rigidity and load-bearing capacity.

[0061] Shock-absorbing design: Shock-absorbing pads or shock absorbers are installed under the base to reduce the impact of equipment vibration on the ground and improve running stability.

[0062] Fixing method: The base and the ground are fixed with expansion bolts or chemical anchor bolts to ensure firmness and reliability. The bolt diameter and spacing are determined according to the equipment weight and vibration level.

[0063] Cable and pipe layout: Reserve inlets and outlets for cables and air pipes on the base, and design reasonable wiring and pipe channels to ensure safety and aesthetics.

[0064] The paper pressing roller 9 cooperates with the driving roller to convey the paper smoothly by squeezing. The paper pressing roller is in the shape of an elongated cylinder and is installed by a bearing.

[0065] The paper pressing roller 9 is made of aluminum alloy, stainless steel or rubber-coated steel pipe, taking into account both lightness and wear resistance. The surface of the paper pressing roller 9 is sprayed with polytetrafluoroethylene (PTFE) or polyurethane (PU) coating at high temperature to improve wear resistance and anti-sticking properties. Pressure is applied through elastic elements such as springs or cylinders, and a pressure adjustment mechanism is designed to adjust the pressure according to the thickness and material of the paper.

[0066] The driving roller 10 is the same as above. The driving roller 10 cooperates with the paper pressing roller to drive the paper to be transported forward. The appearance is similar to that of the paper pressing roller.

[0067] The roller surface 10 is coated with a wear-resistant rubber layer, such as nitrile rubber (NBR) or polyurethane rubber, to increase the friction coefficient and prevent slipping. The roller surface adopts a convex design, and the middle diameter is slightly larger than the two ends to compensate for the deformation of the roller under pressure and ensure uniform tension of the paper. Synchronous belts are used between multiple driving rollers to ensure that the speed of each roller is consistent to avoid wrinkles or tears in the paper.

[0068] The driving motor 11 provides power for the device and drives each roller through a belt drive. It is a cylindrical motor.

[0069] This embodiment preferably uses an AC servo motor or a brushless DC motor, such as a 130 series servo motor. It uses a planetary reducer or a harmonic reducer to increase torque and reduce speed fluctuations.

[0070] The above components are flexibly assembled on the frame through bearings, bolts, belts, etc., and together form a highly automated packaging paper cleaning production line. The paper passes through the paper guide roller, cleaning brush, paper pressing roller and driving roller in turn, and is finally rolled up on the paper storage roller. The whole process is automated and smooth. The device uses a brush roller to clean the paper surface, and the structure is relatively simple and compact, which can effectively improve the cleanliness and production efficiency of the packaging paper.

[0071] The embodiment of the utility model proposes an automatic cleaning packaging paper production device, which realizes efficient cleaning in the packaging paper production process through reasonable configuration and automatic control of components such as a frame, a paper storage roller, a paper guide roller, and a paper cleaning brush. The device can deeply clean the surface of paper, improve product quality, reduce manual labor intensity, and improve production efficiency, and has good application prospects.

[0072] The automatic cleaning packaging paper production device is an automated solution to the pain points of the cleaning process in traditional packaging paper production. Through deep cleaning with soft bristles, modular design, automated control and other technical means, the device can significantly improve the cleanliness and production efficiency of packaging paper, bringing greater economic benefits and competitive advantages to packaging paper manufacturers. At the same time, the design ideas and key technologies of the device can provide useful references for other similar application fields.
