Description

Technical Field

[0001] This utility model relates to the field of specialty paper production technology, specifically to a drying box windproof curtain used in specialty paper production. Background Technology

[0002] The windproof curtain of a specialty paper drying box is a core auxiliary component in the drying process. Specifically designed for the high-temperature and high-humidity conditions of specialty paper production, it is made of a special material that is heat-resistant, anti-aging, and highly flexible. It fits tightly against the inlet and outlet of the drying box, effectively preventing the leakage of hot air from the box, reducing heat loss and energy consumption, while also isolating cold air from the outside, maintaining the stability of temperature and airflow inside the box. Its precise sealing performance prevents problems such as uneven heating, wrinkling, and moisture content fluctuations in specialty paper during the drying process, ensuring that key indicators such as paper strength and smoothness meet standards. This windproof curtain is compatible with different specifications of drying equipment, is easy to install, wear-resistant, and durable. It can meet the continuous operation requirements of specialty paper production and is an important supporting component for improving drying efficiency and ensuring product quality.

[0003] The existing drying ovens cannot control the heating of the cross-section of specialty paper, resulting in uneven drying and inconsistent color of the cross-section, which affects the appearance and quality of the product. To address this, we propose a windproof curtain for drying ovens used in specialty paper production. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide a windproof curtain for a drying box in the production of special paper, which can effectively solve the problem of uneven drying in the original drying box in the prior art.

[0005] The technical solution adopted by this utility model is as follows: a windproof curtain for a drying box in the production of special paper, comprising a motor and a coiled spring seat. A rotating shaft is fixedly installed at the output end of the motor. A curtain drum is fixedly installed on the outer wall of the rotating shaft. A curtain plate is provided on the outer wall of the curtain drum. A rotating shaft is rotatably installed at the bottom end of the coiled spring seat. A wire rope drum is fixedly installed on the outer wall of the rotating shaft. A wire rope body is provided on the outer wall of the wire rope drum. A coiled spring body is provided between the coiled spring seat and the rotating shaft, and the wire rope body is close to the curtain plate. A wire rope clamp is fixedly installed at one end of the air curtain plate. A positioning groove and a through hole are provided at the end of the air curtain plate near the wire rope body. A connecting plate is provided at the end of the air curtain plate near the wire rope body. An installation groove is provided at the end of the connecting plate near the air curtain plate. A positioning block is fixedly installed on the inner wall of the installation groove. A through hole is provided on the outer wall of the connecting plate. A screw is inserted into the outer wall of the connecting plate. A nut is threaded onto the outer wall of the screw. A hook hole is provided at the end of the connecting plate near the wire rope clamp. A connecting buckle is provided between the connecting plate and the wire rope clamp.

[0006] Preferably, the positioning block and the positioning groove are plug-in installed, and the air curtain plate is adapted to the mounting groove.

[0007] Using the above technical solution, workers insert the air curtain plate into the installation groove and simultaneously insert the positioning block into the positioning groove, which enables rapid positioning of the connecting plate.

[0008] Preferably, the screw passes through through hole one and through hole two, the diameters of through hole one and through hole two are the same, and the nut abuts against the connecting plate.

[0009] With the above technical solution, after the connecting plate is quickly positioned, the workers insert the screw through the first and second through holes, and then thread the nut to the screw so that the nut abuts against the connecting plate, which can realize the quick positioning of the connecting plate. After long-term use, it is convenient to inspect or replace it.

[0010] Preferably, the air curtain plate is made of 304 stainless steel.

[0011] Through the above technical solution, the air curtain plate made of 304 stainless steel has the characteristics of high temperature resistance and moisture corrosion resistance, which prevents the air curtain plate from rusting. In addition, 304 stainless steel has high strength and can withstand long-term pulling, reducing the frequency of replacement and reducing production and maintenance costs.

[0012] Preferably, the connecting buckle is adapted to the hook hole and the connecting buckle is adapted to the wire rope clamp.

[0013] Using the above technical solution, workers connect the wire rope clamp to the connecting plate via a connecting buckle. When the ventilation opening needs to be increased, the worker starts the motor, causing the motor's output shaft to rotate forward. The rotation of the output shaft drives the air curtain drum to rotate, winding the air curtain panel onto the outside of the air curtain drum. At the same time, it causes the wire rope body to tighten the coiling spring body. When the ventilation opening needs to be decreased, the worker starts the motor, causing the motor's output shaft to rotate in reverse. The rotation of the output shaft drives the air curtain drum to rotate, unwinding the air curtain drum. At the same time, the coiling spring body releases torque, causing the wire rope drum to rotate in reverse and wind up the wire rope body, thereby straightening the air curtain panel. The shielding length of the air curtain panel is determined by the number of rotations of the motor's output shaft. The closure degree of the air curtain panel can be adjusted in real time according to the horizontal section detection results of the downstream moisture detector. The uniformity of the product's horizontal dryness is greatly improved, the color difference on the paper surface is reduced, and the product yield is improved.

[0014] Preferably, there are two identical wire rope bodies, and the two wire rope bodies are symmetrically distributed about the center line of the wind curtain plate.

[0015] The above technical solution, through the design of two steel wire rope bodies, ensures that the air curtain plate is subjected to uniform force during opening and closing, avoiding tilting and jamming. This prevents the air curtain plate from jamming and affecting the production rhythm of specialty paper, while also reducing component wear.

[0016] Preferably, the air curtain drum, air curtain plate, wire rope drum and wire rope body are provided in two identical sets, and the two sets of air curtain drum, air curtain plate, wire rope drum and wire rope body are distributed vertically.

[0017] Through the above technical solution, the design of two sets of air curtain drums, air curtain panels, wire rope drums and wire rope bodies allows the upper and lower sets to work together. The windproof range can be adjusted according to the height of the drying box and the paper specifications, expanding the applicable scenarios of the air curtain panels. It can be adapted to special paper drying equipment of different sizes, and has high adaptability.

[0018] Compared with the prior art, this utility model provides a windproof curtain for a drying box in the production of specialty paper, which has the following beneficial effects: 1. This drying box windproof curtain for special paper production can adjust the closure degree of the windproof curtain plate in real time according to the cross-section detection results of the downstream moisture detector. This greatly improves the uniformity of the cross-section dryness of the product, reduces the color difference of the paper surface, and improves the yield of high-quality products. The windproof curtain plate made of 304 stainless steel has the characteristics of high temperature resistance and moisture corrosion resistance, which prevents the windproof curtain plate from rusting. In addition, the high strength of 304 stainless steel can withstand long-term pulling, reducing the replacement frequency and lowering production and maintenance costs. Through the cooperation of positioning blocks and positioning grooves, windproof curtain plates and mounting grooves and screws, through holes one and two and nuts, the connecting plate can be quickly limited. After long-term use, it is easy to inspect or replace it. 2. This drying box windproof curtain for specialty paper production features a design with two steel wire rope bodies, ensuring even force distribution during curtain opening and closing, preventing tilting and jamming.

[0021] 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.

[0022] Example 1: As Figure 1-6 As shown, this utility model provides a drying box windproof curtain for special paper production, including a motor 1 and a coiled spring seat 2. A rotating shaft 3 is fixedly installed at the output end of the motor 1. A curtain roller 4 is fixedly installed on the outer wall of the rotating shaft 3. A curtain plate 5 is provided on the outer wall of the curtain roller 4. A rotating shaft 6 is rotatably installed at the bottom end of the coiled spring seat 2. A wire rope roller 7 is fixedly installed on the outer wall of the rotating shaft 6. A wire rope body 8 is provided on the outer wall of the wire rope roller 7. A coiled spring body 9 is provided between the coiled spring seat 2 and the rotating shaft 6. A wire rope clamp 1 is fixedly installed at the end of the wire rope body 8 near the curtain plate 5. 0. The end of the air curtain plate 5 near the wire rope body 8 is provided with a positioning groove 11 and a through hole 12. The end of the air curtain plate 5 near the wire rope body 8 is provided with a connecting plate 13. The end of the connecting plate 13 near the air curtain plate 5 is provided with an installation groove 14. The inner wall of the installation groove 14 is fixedly installed with a positioning block 15. The outer wall of the connecting plate 13 is provided with a through hole 16. The outer wall of the connecting plate 13 is inserted and installed with a screw 17. The outer wall of the screw 17 is threaded with a nut 18. The end of the connecting plate 13 near the wire rope clamp 10 is provided with a hook hole 19. A connecting buckle 20 is provided between the connecting plate 13 and the wire rope clamp 10.

[0023] Specifically, the positioning block 15 and the positioning groove 11 are plug-in installed, and the air curtain plate 5 is adapted to the mounting groove 14. The advantage is that when the operator inserts the air curtain plate 5 into the mounting groove 14 and the positioning block 15 into the positioning groove 11, the connecting plate 13 can be quickly positioned.

[0024] Specifically, the screw 17 passes through through hole 12 and through hole 16, both with the same diameter. The nut 18 abuts against the connecting plate 13. The advantage is that after quickly positioning the connecting plate 13, the operator can pass the screw 17 through through hole 12 and through hole 16, and then thread the nut 18 onto the screw 17, causing the nut 18 to abut against the connecting plate 13. This allows for quick positioning of the connecting plate 13 and facilitates maintenance or replacement after prolonged use.

[0025] Specifically, the air curtain plate 5 is made of 304 stainless steel. The advantages are that the 304 stainless steel air curtain plate 5 is resistant to high temperatures and moisture corrosion, preventing rust. Furthermore, the high strength of 304 stainless steel allows it to withstand long-term tension, reducing replacement frequency and lowering production and maintenance costs.

[0026] Example 2: Figure 2-6 As shown, this is an improvement on the previous embodiment.

[0027] Specifically, the connecting buckle 20 is compatible with the hook hole 19 and the wire rope clamp 10. The advantage is that workers connect the wire rope clamp 10 to the connecting plate 13 via the connecting buckle 20. When a larger ventilation opening is needed, the worker starts the motor 1, causing its output shaft to rotate forward. This rotation drives the air curtain drum 4 to rotate, winding the air curtain panel 5 onto the outside of the drum 4. Simultaneously, this causes the wire rope body 8 to tighten the coil spring body 9. When a smaller ventilation opening is needed, the worker starts the motor 1, causing its output shaft to rotate in reverse. This rotation drives the air curtain drum 4 to rotate, unwinding the drum 4. Simultaneously, the coil spring body 9 releases torque, causing the wire rope drum 7 to rotate in reverse and wind up the wire rope body 8, thus straightening the air curtain panel 5. The covering length of the air curtain panel 5 is determined by the number of rotations of the motor 1's output shaft, making it highly practical.

[0028] Specifically, there are two identical wire rope bodies 8, which are symmetrically distributed about the center line of the air curtain plate 5. The advantage is that the design of two wire rope bodies 8 ensures that the air curtain plate 5 is subjected to uniform force during opening and closing, avoiding tilting and jamming, preventing the air curtain plate 5 from jamming and affecting the production rhythm of special paper, and reducing component wear.

[0029] Specifically, the air curtain drum 4, air curtain plate 5, wire rope drum 7, and wire rope body 8 are arranged in two identical sets, with the two sets of air curtain drum 4, air curtain plate 5, wire rope drum 7, and wire rope body 8 distributed vertically. The advantage is that, through the design of two sets of air curtain drum 4, air curtain plate 5, wire rope drum 7, and wire rope body 8, the upper and lower sets can work together, and the windproof range can be adjusted according to the height of the drying chamber and the paper specifications. This expands the applicable scenarios of the air curtain plate 5, making it suitable for special paper drying equipment of different sizes, thus exhibiting high adaptability.

[0030] Working principle: During installation, the operator inserts the air curtain plate 5 into the mounting groove 14 and the positioning block 15 into the positioning groove 11, which enables quick positioning of the connecting plate 13. After quickly positioning the connecting plate 13, the operator inserts the screw 17 through the first through hole 12 and the second through hole 16, and then threads the nut 18 onto the screw 17, so that the nut 18 abuts against the connecting plate 13, which enables quick positioning of the connecting plate 13. After long-term use, this facilitates maintenance or replacement. Subsequently, the operator connects the buckle 20... Connect the wire rope clamp 10 to the connecting plate 13. During use, when a larger ventilation opening is needed, the operator starts the motor 1, causing its output shaft to rotate forward. This rotation drives the air curtain drum 4 to rotate, winding the air curtain panel 5 onto the outside of the drum 4. Simultaneously, this causes the wire rope body 8 to tighten and coil the spring body 9. When a smaller ventilation opening is needed, the operator starts the motor 1, causing its output shaft to rotate in reverse. This rotation drives the air curtain drum 4 to unwind, simultaneously coiling the spring body 9. 9. Releasing torque causes the wire rope drum 7 to reverse and rewind the wire rope body 8, thereby straightening the air curtain plate 5. The blocking length of the air curtain plate 5 is determined by the number of rotations of the output shaft of the motor 1. The closure degree of the air curtain plate 5 can be adjusted in real time according to the cross-section detection results of the downstream moisture detector. The uniformity of the cross-section dryness of the product is greatly improved, the color difference of the paper surface is reduced, and the yield of high-quality products is improved. Through the design of two wire rope bodies 8, the air curtain plate 5 is subjected to uniform force during winding and unwinding, avoiding tilting and jamming. It can prevent the air curtain plate 5 from jamming and affecting the production rhythm of special paper, while reducing component wear. The design incorporates two sets of air curtain drums 4, air curtain panels 5, wire rope drums 7, and wire rope bodies 8. The upper and lower sets can work together, and the windproof range can be adjusted according to the height of the drying box and the paper specifications. This expands the applicable scenarios of the air curtain panels 5, making them suitable for special paper drying equipment of different sizes. The air curtain panels 5, made of 304 stainless steel, have the characteristics of high temperature resistance and moisture corrosion resistance, preventing the air curtain panels 5 from rusting. In addition, the high strength of 304 stainless steel can withstand long-term pulling, reducing the frequency of replacement and lowering production and maintenance costs.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
