Description

Technical Field

[0001] The invention relates to the technical field of textile material extrusion equipment, and in particular to a compound-pressed ultra-fine glass fiber processing extrusion device and a use method thereof. Background Art

[0002] The composite pressed form of ultrafine glass fiber usually refers to a form that presents a specific structure and performance after being processed by a special composite pressing process. During the composite pressing process, the originally loose ultrafine glass fiber is further compacted, and the fibers are interwoven more closely to form an orderly and dense three-dimensional network structure. This structure makes the connection between the fibers more stable and improves the overall strength and stability. The composite pressed ultrafine glass fiber raw material to be processed enters from the feed hopper of the feeding mechanism, and the extrusion roller group applies pressure to the glass fiber raw material after the impregnation, so that it is formed and discharged from the discharge port of the discharge mechanism.

[0003] Due to the combined effect of the stickiness of the impregnation material itself and the static electricity attached to the surface of the ultrafine fiber, the impregnation material sticks to the surface of the extrusion roller during extrusion. As production continues, new impregnation materials will continue to adhere and gradually form accumulation, especially some impregnation materials containing solvents. If not handled in time, the impregnation materials will solidify on the roller surface after the solvent evaporates, forming lumps or protrusions, further aggravating the roughness and unevenness of the extrusion roller surface. When extruding the fiber, the protrusions will exert greater pressure on the fiber, while the pressure exerted by the concave parts is smaller. The uneven force on the fiber surface will make the degree of bonding between the fiber and the impregnation material and the degree of compaction between the fibers different, resulting in uneven distribution of product density and thickness, which will further lead to differences in the physical and chemical properties of the fiber products, increase production costs and production cycles, and reduce overall production efficiency. Summary of the invention

An adjusting structure for limiting the movable state of the rotating shaft is provided on the inner wall of the scraper.

[0006] Furthermore, a movable groove is provided in the middle of the scraper, and a limiting groove is symmetrically provided at the bottom end of the movable groove, and a connecting structure is provided inside the limiting groove.

[0007] Furthermore, the scraper consists of a long plate, a short plate and an arc-shaped plate, one end of the long plate is fixedly connected to the arc-shaped plate, the other end of the arc-shaped plate is fixedly connected to the short plate, the adjustment structure is located in the middle of the arc-shaped plate, and the other end of the short plate is arranged on the inner wall of the collection box.

[0008] Furthermore, the adjustment structure includes a clamping ring engaged with the outer wall of the slot, the outer wall of the clamping ring is fixedly connected to a gravity plate, and the other end of the gravity plate is fixedly connected to a stop block.

[0009] Furthermore, the connection structure includes a slider slidably connected to the inner wall of the limiting groove, a stopper is fixedly connected to the side of the slider, an elastic member is elastically connected to the bottom end of the stopper, and in an initial state, the bottom end of the side of the stopper fits with the stopper.

[0010] Furthermore, the upper surface of the stopper adopts a symmetrical inclined surface design.

[0011] Furthermore, a combing plate is provided at the upper end of the immersion tank, a baffle is symmetrically fixed on the top of the combing plate, a side plate is provided in the middle of the top of the combing plate, an arc-shaped design is adopted on the side of the side plate close to the inside of the immersion tank, a guide groove is provided on the lower surface of the side plate, and the guide groove adopts an inverted triangle design.

[0012] A method for using a compound-pressing ultra-fine glass fiber processing extrusion device comprises the following steps: S1: The composite-pressed ultra-fine glass fiber raw material to be processed is pressed and immersed in the impregnation material by the impregnation roller arranged inside the impregnation tank, and the impregnation material is in full contact with the surface of the ultra-fine glass fiber; S2: The ultra-fine glass fiber after impregnation is moved out of the impregnation tank under the drive of the traction structure, and then passes through the gap between the extrusion rollers. The bottom surface of the ultra-fine glass fiber contacts the arc surface of the side plate, and the excess impregnation on its lower surface can be scraped off. The scraped impregnation falls into the guide groove along the side plate. Under the action of gravity, the impregnation will slide along the surface of the guide groove and automatically flow to the impregnation tank, avoiding the impregnation scattering around the equipment or on the ground, causing material waste and dirty environment; S3: The fibers adhere to each other due to the viscosity of the impregnation material, forming an aggregate with certain flexibility but relatively loose structure. As the impregnated ultrafine glass fibers are transferred between the squeezing rollers, the fiber aggregate begins to contact the surface of the squeezing roller. At the moment of contact, due to the pressure on the surface of the squeezing roller, the impregnation material on the outside of the fiber aggregate is squeezed first, and part of the impregnation material will be squeezed to the surface of the fiber aggregate, making it more closely in contact with the squeezing roller. Under the continuous pressure of the squeezing roller, the internal structure of the fiber aggregate changes, the distance between the fibers is further compressed, and the impregnation material is redistributed between the fibers, gradually filling the gaps between the fibers, making the entire aggregate denser. In this process, the excess impregnation material will be squeezed out of the fiber aggregate and adhere to the surface of the squeezing roller; S4: In the initial state, the side surfaces of the two squeezing rollers designed symmetrically up and down are smooth and fit with the rubber pad. As the squeezing roller rotates, the area where the impregnation material adheres will directly contact the rubber pad. For colloidal and lightly cured impregnation materials, too much scraping force is not required. The rubber pad automatically adjusts the pressure according to the distribution and shape of the impregnation material, which can not only ensure the scraping effect, but also avoid damage to the surface of the squeezing roller due to excessive pressure, and reduce the risk of deformation or breakage of the scraper. For seriously dried impregnation materials, the force on the rubber pad increases, and the block overcomes the elastic force of the elastic member and slides downward. When the block moves downward, the clamping ring slides downward under the gravity of the gravity plate and the block, and the clamping ring is no longer engaged with the slot, and the shaft is no longer restricted by other structures. The shaft changes its angle immediately under the action of external force, so that the contact area and angle between the positioning frame and the impregnation material reach a better state, and it can more effectively cut into the junction of the dried impregnation material and the squeezing roller to scrape it from the roller surface.

[0013] Compared with the prior art, the technical solution provided by the present invention has the following beneficial effects: The present invention is provided with a scraper, which can be automatically adjusted according to different forms of the impregnated material to ensure accurate scraping under various circumstances. When encountering undried impregnated material, a stable angle is maintained to maintain a normal scraping effect. When facing dried impregnated material, the angle is changed to enhance the scraping ability, ensuring that the surface of the extrusion roller is always kept clean, providing good conditions for subsequent production processes, and achieving efficient scraping effect through angle adaptive adjustment, reducing product quality problems caused by residual impregnated material, avoiding frequent shutdowns due to cleaning of a large amount of residual impregnated material, ensuring the stability and continuity of the production process, and making the positioning frame more evenly stressed.

[0014] The present invention is provided with an impregnation tank, which can effectively remove excess impregnation on the lower surface of the fiber, so that the amount of impregnation on each part of the fiber is more uniform. The uniform impregnation can ensure consistent material properties, avoid performance differences such as strength and toughness caused by uneven impregnation, improve the quality of subsequent products, and reduce the problem of uneven pressure distribution caused by excessive impregnation on the lower surface. After being scraped off by a combing plate, when the fiber enters the extrusion process, the extrusion roller is subjected to more uniform force, which reduces the wear of the extrusion roller and extends its service life. At the same time, the stability of the extrusion process and the consistency of product quality are guaranteed, the risk of appearance defects caused by excessive impregnation on the lower surface is reduced, and the aesthetics and market competitiveness of the product are improved.

DETAILED DESCRIPTION

[0018] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0019] The present invention will be further described below in conjunction with the embodiments.

[0020] Example:

[0021] See also Figure 2-Figure 8 The present invention provides a technical solution: a compound pressure type ultra-fine glass fiber processing extrusion device, such as Figure 2 As shown, the device includes an extrusion part 1, a soaking tank 3 is arranged on one side of the extrusion part 1, and a heating element is built in the soaking tank 3 to ensure that the soaking material placed inside is in a fluid state. A soaking roller is arranged inside the soaking tank 3 to press and immerse the ultrafine glass fiber in the soaking material to ensure that the soaking material is in full contact with the surface of the ultrafine glass fiber. The extrusion part 1 includes a fixed frame 11, and a squeezing roller 12 is symmetrically arranged in the middle of the fixed frame 11. The gap between the two squeezing rollers 12 is adjusted as needed. The ultrafine glass fiber that has passed through the soaking material is transmitted from the side of the squeezing roller 12 close to the soaking tank 3 to the side away from the soaking tank 3. The squeezing roller 12 squeezes the ultrafine glass fiber that has passed through the soaking material to form it and then output it.

[0022] However, since ultrafine fibers have extremely fine diameters, their specific surface area is much larger than that of ordinary fibers. At the same time, they often have rich pore structures, and the surfaces of ultrafine fibers often contain more polar groups, such as hydroxyl groups and carboxyl groups. These groups can interact with certain components in the impregnation material through hydrogen bonds, van der Waals forces, etc., further enhancing the fiber's adsorption capacity for the impregnation material. The impregnation material can not only adhere to the surface of a single fiber, but may also accumulate in the gaps between the fibers. This interaction between the fibers makes it easier for the impregnation material to remain in the fiber aggregate, thereby increasing the overall adhesion amount. Excessive impregnation material is concentrated on the surface of the ultrafine glass fibers. At the same time, since the impregnation material is sticky, it will adhere to the surface of the extrusion roller 12 during the extrusion process. Excessive impregnation material is more likely to cause a large amount of residue During the extrusion process, accumulation or uneven smearing will form on the surface of the extrusion roller 12, which will destroy the flatness of the surface of the extrusion roller 12, and the originally smooth surface will become uneven, which will not only affect the molding quality of subsequent products, but also if it is not cleaned in time, the residual impregnation material will be difficult to remove by conventional cleaning methods after it dries up, and special cleaning agents and tools are required, which increases the difficulty and time cost of cleaning work. Therefore, the present invention is provided with a processing part 2, and the processing part 2 can be used to clean the surface of the extrusion roller 12 in time without stopping the machine. While the extrusion roller 12 rotates to extrude and transmit the ultra-fine glass fiber, the surface of the extrusion roller 12 can be fully cleaned, which not only reduces the manpower and material costs, but also improves the production efficiency of the device.

[0023] refer to Figure 2 and Figure 3 The scraper 22 is composed of a long plate, a short plate and an arc-shaped plate. One end of the long plate is fixedly connected to the arc-shaped plate, and the other end of the arc-shaped plate is fixedly connected to the short plate. The adjustment structure 24 is located in the middle of the arc-shaped plate, and the other end of the short plate is arranged on the inner wall of the collecting box 23. A movable groove 223 is opened in the middle of the scraper 22, and a limiting groove 222 is symmetrically opened at the bottom end of the movable groove 223, and a connecting structure 25 is arranged inside the limiting groove 222.

[0024] In the initial state, the two squeezing rollers 12 designed symmetrically up and down have smooth surfaces and fit with the rubber pad 221. As the squeezing rollers 12 rotate, the area where the impregnation material is adhered will directly contact the rubber pad 221. For the colloidal and lightly cured impregnation materials, not too much scraping force is required. The rubber pad 221 automatically adjusts the pressure according to the distribution and shape of the impregnation materials, which can not only ensure the scraping effect, but also avoid damage to the surface of the squeezing rollers 12 due to excessive pressure, and at the same time reduce the risk of deformation or breakage of the scraper 22. At this time, the force exerted by the colloidal and lightly cured impregnation materials on the rubber pad 221 is not enough to overcome the elastic force of the connecting structure 25 itself. At this time, the angle between the scraper 22 and the squeezing roller 12 is large, which can effectively scrape the colloidal and lightly cured impregnation materials.

[0025] However, in actual use, part of the impregnation material adhered to the surface of the squeezing roller 12 will solidify or dry after being exposed to the air for a period of time. The degree of solidification or drying of the impregnation material at different positions may be different. The positioning frame 21 simply fixed at a certain angle cannot be flexibly adjusted according to the specific situation of the impregnation material. For the impregnation material with light solidification, not too much scraping force is required, while for the impregnation material with serious drying, greater pressure and a more suitable angle are required. The single-angle positioning frame 21 is difficult to meet these different requirements at the same time, resulting in an unsatisfactory scraping effect. Therefore, the present invention is provided with an adjustment structure 24, and the angle of the positioning frame 21 is adjusted by the adjustment structure 24. In the initial state, the angle between the positioning frame 21 and the squeezing roller 12 is large, and the impregnation material attached to its surface that has not dried can be scraped off. When encountering solidified and dried impregnation material, the positioning frame 21 changes its angle under the restriction of the adjustment structure 24. At this time, the angle between the positioning frame 21 and the squeezing roller 12 is small. The positioning frame 21 can use the force generated by the rotation direction and angle of the squeezing roller 12 to better destroy the combination of the impregnation material and the roller surface.

[0026] refer to Figure 5 , Figure 6 and Figure 7 The rotating shaft 26 passes through the middle of the arc plate, and both ends of the rotating shaft 26 are embedded in the inner wall of the collecting box 23. The outer surface of the rotating shaft 26 is evenly provided with grooves 261. The adjusting structure 24 includes a snap ring 243 that is engaged with the groove 261. The outer wall of the snap ring 243 is fixedly connected with a gravity plate 244, and the other end of the gravity plate 244 is fixedly connected with a stopper 245. The connecting structure 25 includes a slider 253 that is slidably connected to the inner wall of the limiting groove 222. The side of the slider 253 is fixedly connected with a stopper 252. The bottom end of the stopper 252 is elastically connected with an elastic member 251. In the initial state, the bottom end of the side of the stopper 252 is in contact with the stopper 245, and the upper surface of the stopper 252 adopts a symmetrical inclined surface design.

[0027] For seriously dried and hardened impregnated materials, the force on rubber pad 221 increases, and the excessive force is transmitted to block 252, which will cause block 252 to overcome the elastic force of elastic member 251 and slide downward. While block 252 moves downward, snap ring 243 slides downward under the gravity of gravity plate 244 and stop block 245, and stop block 245 moves from a position in contact with the bottom end of the side of block 252 to a position in contact with the top end of the side of block 252. Clip ring 243 is no longer engaged with slot 261, and shaft 26 is no longer restricted by other structures. Under the action of external force, shaft 26 immediately drives positioning frame 21 fixed thereto to change its angle, so that the contact area and angle between positioning frame 21 and impregnated materials reach a more optimal state, and the junction of dried and hardened impregnated materials and extrusion roller 12 is more effectively cut into to scrape it off the roller surface.

[0028] Therefore, when encountering dried impregnation material, the positioning frame 21 is subjected to increased force and then changes its angle, so that the contact area and angle between the positioning frame 21 and the impregnation material reach a more optimal state, and more effectively cut into the junction of the dried impregnation material and the squeezing roller 12, and scrape it from the roller surface. Compared with the fixed-angle positioning frame 21, it can better adapt to the change of the state of the impregnation material, greatly improve the scraping efficiency, and reduce the residual impregnation material; it can automatically adjust according to different impregnation material forms to ensure that accurate scraping can be achieved under various conditions, and maintain a stable angle when encountering undried impregnation material to maintain a normal scraping effect; when facing dried impregnation material, the angle is changed to enhance the scraping ability, ensure that the surface of the squeezing roller 12 is always kept clean, and provide good conditions for subsequent production processes. Through the adaptive adjustment of the angle, the positioning frame 21 is subjected to more uniform force, the wear degree of specific parts is reduced, the service life of the positioning frame 21 is extended, the replacement frequency is reduced, and the production cost is reduced; the dried impregnation material is effectively scraped off to prevent its long-term adhesion from causing wear and scratches on the surface of the squeezing roller 12 damage, maintain the surface accuracy and smoothness of the squeezing roller 12, extend the service life of the squeezing roller 12, and reduce the equipment maintenance and replacement costs caused by damage to the squeezing roller 12; the efficient scraping effect reduces product quality problems caused by residual impregnation, avoids frequent shutdowns due to cleaning up a large amount of residual impregnation, ensures the stability and continuity of the production process, and improves production efficiency; the structure adapts to changes in the state of the impregnation under various production conditions, and does not require frequent manual intervention to adjust the angle of the positioning frame 21, which reduces the impact of human factors on production and improves the reliability and stability of the production system; timely and effectively scrape the impregnation on the surface of the squeezing roller 12 to prevent the impregnation from transferring to the product, avoid defects, impurities and other problems on the product surface caused by residual impregnation, and ensure the appearance quality and performance of the product; the stable surface state of the squeezing roller 12 ensures that the extrusion conditions of the product are consistent throughout the production process, which helps to improve the consistency and stability of product quality and improve the overall quality of the product.

[0029] By changing the angle of the positioning frame 21 itself to adapt to the soaked materials in different states, during the scraping process, there is no pause or connection problem when the positioning frame 21 is switched, and the momentary interruption caused by the switching of the positioning frame 21 is avoided, so that a smoother scraping operation can be achieved, the continuity of the scraping is guaranteed, and a stable scraping effect is maintained.

[0030] In the prior art, the ultrafine fibers are suspended in a distance from the impregnation tank 3 to the extrusion process. When the ultrafine fibers are suspended, gravity will affect the distribution of the impregnation material. Since the impregnation material is a liquid or semi-fluid with a certain viscosity, it will tend to flow downward under the action of gravity, causing more impregnation material to accumulate on the lower surface of the fiber. Before the ultrafine glass fibers enter the extrusion roller 12, the impregnation material is likely to remain on the transmission equipment and processing equipment. These residual impregnation materials are difficult to clean after drying, which increases the workload and difficulty of equipment cleaning and maintenance. During extrusion, due to the large amount of impregnation material on the lower surface, the pressure distribution at the contact between the extrusion roller 12 and the fiber will be uneven, the pressure on the lower surface is relatively large, and the pressure on the upper surface is relatively small. Excessive impregnation material is concentrated on the lower surface, which will change the force balance of the fiber during the extrusion process.

[0031] refer to Figure 2 and Figure 8 A combing plate 31 is provided at the upper end of the immersion tank 3, a baffle 34 is symmetrically fixed on the top of the combing plate 31, a side plate 33 is provided in the middle of the top of the combing plate 31, and the side of the side plate 33 close to the inside of the immersion tank 3 adopts an arc design, and a guide groove 32 is provided on the lower surface of the side plate 33, and the guide groove 32 adopts an inverted triangle design.

[0032] The impregnation tank 3 can effectively remove excess impregnation material on the lower surface of the fiber, so that the amount of impregnation material in each part of the fiber is more uniform. The uniform impregnation material can ensure consistent material properties, avoid performance differences such as strength and toughness caused by uneven impregnation material, and improve the quality of subsequent products; reduce the problem of uneven pressure distribution caused by excessive impregnation material on the lower surface. After being scraped off by the combing plate 31, when the fiber enters the extrusion process, the extrusion roller 12 is subjected to more uniform force, which reduces the wear of the extrusion roller 12 and extends its service life. At the same time, the stability of the extrusion process and the consistency of product quality are guaranteed; reduce the risk of appearance defects caused by excessive impregnation material on the lower surface, and improve the aesthetics and market competitiveness of the product.

[0033] The special design of the combing plate 31 can effectively collect excess soaking material. Due to the arc surface design of the side plate 33 and the inclined design of the guide groove 32, the soaking material will tilt toward the inside of the soaking tank 3. Under the action of gravity, the soaking material will slide along the surface of the side plate 33 and the guide groove 32 and automatically flow into the soaking tank 3, thereby preventing the soaking material from scattering around the equipment or on the ground, causing material waste and a dirty environment.

[0034] Allowing the soaking material to flow back into the reflux tank realizes the recycling and reuse of the soaking material, which helps to improve the utilization rate of the soaking material and reduce production costs. In this way, the soaking material that may have been discarded can participate in the production process again, reducing the consumption of raw materials; preventing the soaking material from accumulating on the side of the soaking tank 3 helps to keep the working area clean and hygienic, and reduce the safety hazards caused by the residual soaking material. At the same time, a clean working environment is also conducive to the maintenance and maintenance of the equipment, and extends the service life of the equipment; the setting of the soaking material reflux makes the production process smoother and more efficient, automatically collects and refluxes the soaking material, reduces the workload of manual cleaning and handling of the soaking material, improves production efficiency, and makes the entire production process more automated and standardized.

[0035] See also Figure 1 On the other hand, the present invention provides a method for using a compound-pressed ultra-fine glass fiber processing extrusion device, comprising the following steps: S1: The composite ultra-fine glass fiber raw material to be processed is pressed and immersed in the impregnation material by the impregnation roller arranged inside the impregnation tank 3, and the impregnation material is in full contact with the surface of the ultra-fine glass fiber; S2: The ultra-fine glass fiber after the soaking is driven by the traction structure to move out of the soaking tank 3, and then passes through the gap between the extrusion rollers 12. The bottom surface of the ultra-fine glass fiber contacts the arc surface of the side plate 33, and the excess soaking material on its lower surface can be scraped off. The scraped soaking material falls into the guide groove 32 along the side plate 33. The soaking material will slide along the surface of the guide groove 32 under the action of gravity and automatically flow to the soaking tank 3, so as to avoid the soaking material being scattered around the equipment or on the ground, causing material waste and dirty environment; S3: The fibers adhere to each other due to the viscosity of the impregnation material, forming an aggregate with certain flexibility but relatively loose structure. As the ultra-fine glass fibers after impregnation are transmitted between the squeezing rollers 12, the fiber aggregate begins to contact the surface of the squeezing roller 12. At the moment of contact, due to the pressure on the surface of the squeezing roller 12, the impregnation material on the outside of the fiber aggregate is squeezed first, and part of the impregnation material will be squeezed to the surface of the fiber aggregate, making it more closely in contact with the squeezing roller 12. Under the continuous pressure of the squeezing roller 12, the internal structure of the fiber aggregate changes, the distance between the fibers is further compressed, and the impregnation material is redistributed between the fibers, gradually filling the gaps between the fibers, making the entire aggregate denser. In this process, excess impregnation material will be squeezed out of the fiber aggregate and adhere to the surface of the squeezing roller 12; S4: In the initial state, the side surfaces of the two squeezing rollers 12 designed symmetrically up and down are smooth and fit with the rubber pad 221. As the squeezing rollers 12 rotate, the area where the impregnation material adheres will directly contact the rubber pad 221. For the colloid-like and lightly cured impregnation material, it does not require too much scraping force. The rubber pad 221 automatically adjusts the pressure according to the distribution and shape of the impregnation material, which can not only ensure the scraping effect, but also avoid damage to the surface of the squeezing roller 12 due to excessive pressure, and at the same time reduce the risk of deformation or breakage of the scraper 22. For severe dryness, The force on the rubber pad 221 increases, and the stopper 252 overcomes the elastic force of the elastic member 251 and slides downward. When the stopper 252 moves downward, the snap ring 243 slides downward under the gravity of the gravity plate 244 and the stopper 245, and the snap ring 243 is no longer engaged with the slot 261. The shaft 26 is no longer restricted by other structures. The shaft 26 changes its angle under the action of external force, so that the contact area and angle between the positioning frame 21 and the soaked material reach a more optimal state, and the dry soaked material and the extrusion roller 12 are more effectively cut into the junction, and the squeeze roller 12 is scraped off the roller surface.

8. The method for using the compound-pressed ultra-fine glass fiber processing extrusion device according to any one of claims 1 to 7, characterized in that: The steps include: S1: The composite-pressed ultra-fine glass fiber raw material to be processed is pressed and immersed in the impregnation material by the impregnation roller arranged inside the impregnation tank, and the impregnation material is in full contact with the surface of the ultra-fine glass fiber; S2: The ultra-fine glass fiber after impregnation is moved out of the impregnation tank under the drive of the traction structure, and then passes through the gap between the extrusion rollers. The bottom surface of the ultra-fine glass fiber contacts the arc surface of the side plate, and the excess impregnation on its lower surface can be scraped off. The scraped impregnation falls into the guide groove along the side plate. Under the action of gravity, the impregnation will slide along the surface of the guide groove and automatically flow to the impregnation tank, avoiding the impregnation scattering around the equipment or on the ground, causing material waste and dirty environment; S3: The fibers adhere to each other due to the viscosity of the impregnation material, forming an aggregate with certain flexibility but relatively loose structure. As the impregnated ultrafine glass fibers are transferred between the squeezing rollers, the fiber aggregate begins to contact the surface of the squeezing roller. At the moment of contact, due to the pressure on the surface of the squeezing roller, the impregnation material on the outside of the fiber aggregate is squeezed first, and part of the impregnation material will be squeezed to the surface of the fiber aggregate, making it more closely in contact with the squeezing roller. Under the continuous pressure of the squeezing roller, the internal structure of the fiber aggregate changes, the distance between the fibers is further compressed, and the impregnation material is redistributed between the fibers, gradually filling the gaps between the fibers, making the entire aggregate denser. In this process, the excess impregnation material will be squeezed out of the fiber aggregate and adhere to the surface of the squeezing roller; S4: In the initial state, the side surfaces of the two squeezing rollers designed symmetrically up and down are smooth and fit with the rubber pad. As the squeezing roller rotates, the area where the impregnation material adheres will directly contact the rubber pad. For colloidal and lightly cured impregnation materials, too much scraping force is not required. The rubber pad automatically adjusts the pressure according to the distribution and shape of the impregnation material, which can not only ensure the scraping effect, but also avoid damage to the surface of the squeezing roller due to excessive pressure, and reduce the risk of deformation or breakage of the scraper. For seriously dried impregnation materials, the force on the rubber pad increases, and the block overcomes the elastic force of the elastic member and slides downward. When the block moves downward, the clamping ring slides downward under the gravity of the gravity plate and the block, and the clamping ring is no longer engaged with the slot, and the shaft is no longer restricted by other structures. The shaft changes its angle immediately under the action of external force, so that the contact area and angle between the positioning frame and the impregnation material reach a better state, and it can more effectively cut into the junction of the dried impregnation material and the squeezing roller to scrape it from the roller surface.
