Description

Technical Field

[0001] This invention relates to the field of machinery technology in the textile industry, and in particular to a modular frame for a sizing machine. Background Technology

[0002] In the production process of electronic-grade fiberglass cloth, the sizing machine undoubtedly plays a crucial role, becoming one of the indispensable key pieces of equipment. Its core functions cover several key stages, mainly including precise sizing of the warp yarns to ensure yarn uniformity and strength; followed by pressing the sizing process, using appropriate pressure to fully penetrate the sizing agent into the yarn, further improving the yarn's quality and stability; finally, the sizing machine is also responsible for the drying stage, efficiently drying the sized yarns to ensure they reach the ideal dryness state, laying a solid foundation for subsequent production processes.

[0003] Traditional pulping machines, due to their original design not considering dust control requirements, suffer from severe impacts on production quality, equipment lifespan, and operating environment. Currently, the industry has adopted some temporary solutions to address the dust problem, such as installing simple protective covers above the pulp tank, using plastic sheets for temporary shielding, or increasing the frequency of manual cleaning.

[0004] However, in terms of sealing performance, energy efficiency ratio, and maintenance costs, it cannot meet the high production standards of electronic-grade fiberglass cloth. Simple protective covers are usually loosely structured and cannot effectively block the path of dust intrusion. Plastic sheet coverings will affect the operator's observation and operation of the equipment and are easily damaged. Increasing the frequency of manual cleaning not only consumes a lot of manpower and resources, but may also fail to achieve the ideal dust prevention effect due to untimely or incomplete cleaning. Summary of the Invention

[0005] The summary section of this invention provides a brief overview of the concepts, which will be described in detail in the detailed description section that follows. This summary section is not intended to identify key or essential features of the claimed technical solutions, nor is it intended to limit the scope of the claimed technical solutions.

[0006] This invention provides a modular frame for a pulping machine to solve the technical problems mentioned in the background section above.

[0007] The modular frame for a pulping machine of the present invention includes a frame body that covers the pulp tank and machine head area of ​​an electronic grade glass fiber cloth production line. The frame body is composed of load-bearing legs and a top cover. The top of the load-bearing legs is bolted with keels for supporting the top cover. The front and back of the keel are equipped with multiple sets of first leather curtains along its length. Each set of first leather curtains has a lead strip connected to its bottom and a magnetic sealing strip connected to its inner side. An LED light for lighting is installed inside the keel below the top cover. Second leather curtains that can adjust the opening size according to the amount of yarn are installed on the left and right sides of the keel.

[0008] Optionally, the front and rear surfaces of the top cover are provided with louvers, which are connected to the air conditioning vents through the air guide plate.

[0009] Optionally, the number of load-bearing legs is four sets, which are bolted to the bottom corner of the keel. Each set of load-bearing legs has a positioning plate welded to its bottom, and the positioning plate is fixed to the ground with expansion bolts.

[0010] Optionally, a crossbeam is welded between two adjacent sets of load-bearing legs, and a reinforcing rib is welded to the crossbeam at the inside corner formed by the load-bearing legs.

[0011] Optionally, the bottom of the keel is bolted to a base, and the bottom of the base is rotatably connected to a positioning U-shaped component. The positioning U-shaped component is sleeved on the top of the first leather curtain and fixed with screws.

[0012] Optionally, both the lead strip and the magnetic sealing strip are fixed to the first leather curtain with cloth, and galvanized steel plates are laid on the ground at the position corresponding to the magnetic sealing strip.

[0013] Optionally, the second curtain is in multiple sets and is equidistantly distributed along the width of the keel. A dual-head motor is installed at the center of the top of the keel, and lead screws are connected to the output ends of the dual-head motor on both sides.

[0014] Optionally, a positioning strip is fixed to the top of multiple sets of the second leather curtains, and a traction block connected to one end of the positioning strip is threaded onto the outer wall of the screw.

[0015] Optionally, the top of the keel is provided with a clearance groove for the traction block to move, and the other end of the positioning cloth strip is fixed in the clearance groove.

[0016] Optionally, the top of the keel is provided with a lead screw housing sleeved on the outside of the lead screw, and the end of the lead screw is rotatably connected inside the lead screw housing.

[0017] The above embodiments of the present invention have the following beneficial effects: by effectively covering the slurry tank and machine head area with the frame body, and by assembling the first and second curtains, dust intrusion can be blocked, creating a relatively clean environment for the production of electronic grade glass fiber cloth, and meeting the strict dust prevention requirements of high-standard production. In addition, the lead strip connected to the bottom of the first curtain uses its own weight to make the curtain hang naturally, enhancing the sealing performance. The magnetic sealing strip connected to the inside further improves the sealing effect by interacting with the galvanized steel plate laid on the ground, effectively preventing dust from entering through the gap between the curtain and the ground. At the same time, the double-headed motor drives the screw to rotate, which allows for flexible adjustment of the opening size of the second curtain, ensuring the normal passage of yarn while minimizing the leakage of dust.

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0024] This disclosure will now be described in detail with reference to the accompanying drawings and embodiments.

[0025] Please see Figures 1 to 7 The modular frame for a pulping machine of the present invention includes a frame body 100, which covers the pulp tank and machine head area of ​​the electronic grade glass fiber cloth production line. The frame body 100 is composed of load-bearing legs 110 and a top cover 120. The top of the load-bearing legs 110 is bolted with a keel 112 for supporting the top cover 120. The front and back of the keel 112 are equipped with multiple sets of first leather curtains 140 along its length. Each set of first leather curtains 140 is connected to a lead strip 170 at its bottom. The inner side of the first leather curtain 140 is connected to a magnetic sealing strip 160. An LED light 150 for lighting is installed inside the keel 112 below the top cover 120. Second leather curtains 180 that can adjust the opening size according to the amount of yarn are installed on the left and right sides of the keel 112.

[0026] Both the front and rear surfaces of the top cover 120 are provided with louvers 130, which are connected to the air conditioning vents through the deflector plate.

[0027] There are four sets of load-bearing legs 110, which are bolted to the bottom corner of the keel 112. Each set of load-bearing legs 110 has a positioning plate 111 welded to the bottom, and the positioning plate 111 is fixed to the ground with expansion bolts.

[0028] A crossbeam 113 is welded between two adjacent sets of load-bearing legs 110, and a reinforcing rib 114 is welded to the crossbeam 113 at the inside corner formed by the load-bearing legs 110.

[0029] The use of reinforcing ribs 114 can effectively enhance the structural strength at the connection between the crossbeam 113 and the load-bearing leg 110, enabling the entire frame body 100 to withstand and remain stable, and preventing deformation or damage. This greatly improves the overall stability and reliability of the frame body, providing a solid guarantee for the normal operation of the electronic-grade fiberglass cloth production line.

[0030] Both the lead strip 170 and the magnetic sealing strip 160 are fixed to the first curtain 140 with cloth 143, and galvanized steel plates are laid on the ground at the positions corresponding to the magnetic sealing strip 160. The magnetic sealing strip 160 is an iron boron magnet with a magnetic induction intensity ≥1000 Gauss; it can be attracted to the galvanized steel plate laid on the ground and can block fine dust; this magnetic sealing method has good sealing performance and adaptability. Even if there is some unevenness on the ground, the magnetic sealing strip can be attracted to the galvanized steel plate by its own magnetism to form a continuous sealing surface.

[0031] It is worth noting that the first curtain 140 and the second curtain 171 are made of polyurethane coated fabric with a thickness of 2mm and have the characteristics of temperature resistance of -20℃ to 100℃, which can adapt to the temperature changes in different seasons in the workshop and the heat generated during equipment operation; their surfaces are treated with antistatic agents with a resistance of ≤10^6Ω, which effectively prevents dust from being adsorbed on the surface of the curtains due to static electricity, reduces the frequency of cleaning the curtains, and avoids the impact of static electricity on the production process of electronic grade glass fiber cloth.

[0032] The opening angle of the louver 130 is between 0° and 45°. By adjusting the opening angle of the louver 130, the internal airflow can be balanced to ensure smooth internal air circulation. The louver 130 adopts an automatic control device, which can automatically adjust the opening angle according to parameters such as temperature and humidity in the workshop.

[0033] The dual-head motor 181 can precisely control the rotation angle of the lead screw 184, thereby precisely controlling the moving distance of the traction block 185 and achieving precise adjustment of the opening size of the second curtain 180. When the number of yarns increases, the dual-head motor 181 rotates in the forward direction, the lead screw 184 rotates accordingly, and the traction block 185 moves away from the dual-head motor 181 on the lead screw 184, driving the positioning strip 183 to move, thus making the opening of the second curtain 180 larger to meet the needs of more yarns passing through. Conversely, when the number of yarns decreases, the dual-head motor 181 rotates in the reverse direction, the lead screw 184 rotates in the reverse direction, the traction block 185 moves closer to the dual-head motor 181, the positioning strip 183 moves accordingly, and the opening of the second curtain 180 becomes smaller, reducing unnecessary airflow and lowering the possibility of dust entering.

[0034] The main components of the frame body 100, such as the load-bearing legs 110, the keel 112, and the top cover 120, are all made of lightweight aluminum alloy profiles. While ensuring the overall structural strength of the frame, the weight of the frame is effectively reduced, making it easy to install and disassemble.

[0035] In practical use, the modular frame can be flexibly adjusted and expanded according to the actual layout and needs of the electronic-grade fiberglass cloth production line. For example, when the production line needs to add a slurry tank or machine head equipment, the number of load-bearing legs 110 and keel 112 of the frame body 100 can be increased accordingly to expand the coverage of the frame. At the same time, the number and size of the first curtain 140 and the second curtain 180 can be adjusted according to the specifications and quantity of the yarn to ensure good sealing effect and yarn passage.

[0036] The main frame 100 is located in the pulp tank and machine head area, which can effectively prevent external dust from entering the pulp tank and machine head, avoid dust pollution to the production of electronic grade glass fiber cloth, and improve product quality. Its modular design makes the installation and disassembly of each component convenient. When a component is damaged or needs to be replaced, there is no need to disassemble the entire frame on a large scale. Only the corresponding component needs to be operated, which greatly saves maintenance time and costs.

[0037] The first curtain 140, together with the magnetic sealing strip 160 and the galvanized steel plate on the ground, forms a tight barrier that effectively prevents dust from entering from the bottom. It is not affected by the flatness of the ground and can maintain good sealing performance even on uneven ground.

[0038] Please refer to this carefully. Figure 6 and Figure 7 The second curtain 180 consists of multiple sets and is equidistantly distributed along the width of the keel 112. A double-headed motor 181 is installed at the center of the top of the keel 112, and lead screws 184 are connected to the output ends of the double-headed motor 181 on both sides.

[0039] The top of the multiple sets of second leather curtains 180 is fixed with positioning cloth strips 183, and the outer wall of the screw rod 184 is threaded with a traction block 185 connected to one end of the positioning cloth strips 183.

[0040] The top of the keel 112 is provided with a relief groove 115 for the traction block 185 to move, and the other end of the positioning cloth strip 183 is fixed in the relief groove 115.

[0041] The top of the keel 112 is provided with a screw housing 182 sleeved on the outside of the screw 184, and the end of the screw 184 is rotatably connected to the screw housing 182.

[0042] The second curtain 180 automatically adjusts its opening size based on the amount of yarn, minimizing the risk of dust entering through air circulation while meeting production needs. Meanwhile, the venetian blinds 130's automatic adjustment function adjusts in real time according to workshop environmental parameters, ensuring fresh air and suitable temperature and humidity inside the frame. This provides a stable environment for the production of electronic-grade fiberglass cloth. The lightweight aluminum alloy profile of the overall frame not only provides sufficient strength but also facilitates transportation, installation, and subsequent adjustments and expansions. It adapts well to electronic-grade fiberglass cloth production lines of different sizes and layouts, playing a crucial role in improving production quality, reducing maintenance costs, and increasing production efficiency.

[0043] Please refer to this carefully. Figure 2 and Figure 3 The bottom of the keel 112 is bolted to a base 141, and the bottom of the base 141 is rotatably connected to a positioning U-shaped piece 142. The positioning U-shaped piece 142 is sleeved on the top of the first leather curtain 140 and fixed with screws.

[0044] The installation and removal of the first leather curtain 140 are made convenient. When the first leather curtain 140 needs to be cleaned, replaced or repaired, the positioning U-shaped piece 142 can be removed from the top of the first leather curtain 140 simply by loosening the screws.

[0045] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
