Description

Technical Field

[0001] The invention relates to the technical field of roller-pressing composite, in particular to a high-flexibility kneepad and kneepad fabric roller-pressing composite equipment. Background Art

[0002] Highly flexible knee pads can adapt well to various complex sports movements, whether it is the frequent flexion and extension of the knees during running, or the large bending and twisting of the knees during yoga, dance and other sports. The knee pads can closely follow the movement of the knees and will not limit the range of motion of the joints. This is because its elastic material and reasonable structural design enable the knee pads to maintain good elasticity and fit in different sports postures. When the knees are under pressure, the high flexibility of the knee pads can effectively disperse the pressure to the surrounding muscles and tissues.

[0003] The knee pad fabric roller-compounding equipment combines multiple layers of fabric tightly together through the pressure between rollers. When roller-compounding the knee pad fabric, if there is foreign matter on the surface of the roller, it will affect the normal fit of the fabric on the roller. When the fabric passes through an uneven area, it may be locally squeezed and deformed, or even lifted up and eventually fall off. Summary of the invention

[0006] The middle layer is stitched along the edge of the knee pad to make the outer layer and the middle layer fit closely, including the elastic support layer and the buffer layer. The elastic support layer is the core part of the knee pad and is mainly composed of spandex and polyester elastic fiber elastic materials. Through weaving and composite processes, spandex and polyester elastic fibers are combined together to form an elastic net with good elasticity and shape stability.

[0007] The cushioning layer is made of silicone cushioning material in the middle layer of the knee pad. These materials are distributed around the key parts of the knee, such as the patella and meniscus, to absorb and disperse the impact force generated during exercise.

The impurities are removed by the action of the suction mechanism, especially when the fabric is made of natural fibers, such as cotton, linen, or chemical fibers and polyester fibers that are easy to fluff. This situation is more common. When the rolling component rolls and compounds the fabric, the suction mechanism is turned on to effectively suck away these fiber fragments to keep the working area and fabric clean. The suction force generated by the suction mechanism when working sucks the impurities into the collection box through the mesh plate, so that the impurities fall on the baffle for collection. At the same time, the flocculent dust that follows the impurities into the collection box is grabbed by turning on the rotating mechanism.

At the same time, grabbing grooves are evenly provided on the side of the grabbing plate, so that the flocculent dust entering the collection box can be grabbed, thereby preventing the flocculent dust and fallen fabric fragments from floating when entering the collection box, thereby interfering with the collection work.

Over time, these residues may solidify, resulting in the roller shaft being stuck. The uneven surface of the shaft will not only affect the flatness and composite quality of the fabric, but may also cause abnormal conditions such as adhesion and pulling of the fabric on the roller shaft, and even damage the fabric. When the rolling component is rolling, the roller shaft in the rolling component is in contact with and rotated with the contact shell. A bent plate is provided on the inner side of the contact shell, so that the bent plate can scrape off the solidified glue on the roller shaft. At the same time, a roller is provided on the other side of the bent plate. After the bent plate scrapes and cleans the side of the roller shaft, the roller can contact and rotate with the side of the roller shaft, thereby cleaning and wiping the side of the roller shaft. At the same time, when cleaning the roller shaft, the vacuum machine is turned on and the suction force of the vacuum machine is used to move the ejection mechanism upward, so that the impurities scraped off by the bent plate can enter the inner side of the contact shell through the blanking hole for collection.

[0018] 1. This kind of highly flexible knee pad and knee pad fabric roller-pressing composite equipment is provided with a contact component. If there is foreign matter on the surface of the roller, it will affect the normal fitting of the fabric on the roller. By arranging a bent plate on the inner side of the contact shell, the bent plate can scrape off the solidified glue on the roller shaft. At the same time, by arranging a roller on the other side of the bent plate, after the bent plate scratches and cleans the side of the roller shaft, the roller can contact and rotate the side of the roller shaft to clean and wipe the side of the roller shaft. At the same time, when cleaning the roller shaft, the vacuum machine is turned on and the suction force of the vacuum machine works, so that the ejection mechanism moves upward, so that the impurities scraped off by the bent plate can enter the inner side of the contact shell through the blanking hole for collection.

At the same time, the movable plate is continuously reset and stretched by the second spring, so that the ejection rod drives the ejection plate to resist the inner side of the blanking hole, thereby avoiding the impurities collected in the contact shell from falling.

[0020] 3. This kind of highly flexible knee pad and knee pad fabric rolling and compounding equipment is provided with a collecting component. During the rolling and compounding process of the knee pad fabric, the fibers of the fabric itself may produce debris due to friction, loose cutting edges, etc. If these fiber debris remain on the fabric, it will affect the compounding quality. The fibers of the knee pad fabric may fall off due to pressure and friction, especially when the fabric is made of natural fibers, such as cotton, linen, or chemical fibers and polyester fibers that are easy to fuzz. This situation is more common. When the rolling component rolls and compounds the fabric, the suction mechanism is turned on to effectively suck away these fiber debris through the suction mechanism to keep the working area and fabric clean. The suction force generated by the suction mechanism when it is working sucks impurities into the collection box through the mesh plate, so that the impurities fall on the baffle for collection. At the same time, the flocculent dust that follows the impurities into the collection box is grabbed by turning on the rotating mechanism.

[0021] 4. This kind of highly flexible knee pad and knee pad fabric rolling composite equipment is provided with a grabbing assembly. When the output end of the motor drives the lower fixed plate to rotate through the rotating shaft, the lower fixed plate drives the grabbing rod and the connecting plate to rotate on the baffle.

Over time, these residues can The glue solidified on the roller shaft can be solidified, resulting in an uneven roller surface, which not only affects the flatness and composite quality of the fabric 8, but may also cause the fabric 8 to adhere to, pull, or other abnormal conditions on the roller shaft, or even damage the fabric 8. When the rolling component 6 performs rolling work, when the roller shaft in the rolling component 6 contacts and rotates with the contact shell 91, a bent plate 93 is provided on the inner side of the contact shell 91, so that the bent plate 93 can scrape off the solidified glue on the roller shaft. At the same time, a roller 94 is provided on the other side of the bent plate 93.

[0046] When working, the unwinding component 4 is started to slowly release the fabric 8 from the roll. During the unwinding process, the tension of the fabric 8 is maintained stable by the tension control system. After the fabric 8 comes out of the unwinding component 4, it is guided by the guide component 7. The position and angle of the guide component 7 can be adjusted according to the conveying path of the fabric 8 to ensure that the fabric 8 can accurately move toward the rolling component 6. The surface of the guide roller is usually smooth to reduce the friction on the fabric 8 and prevent the surface of the fabric 8 from being scratched. For the normal temperature rolling composite equipment, before the fabric 8 enters between the rolling components 6, it is necessary to adjust the position and angle of the fabric 8 according to the fabric 8. The pressure between the rollers of the rolling component 6 is adjusted according to the characteristics and compounding requirements. The appropriate pressure value is set by a mechanical adjustment device, a hydraulic system or a pneumatic system. For example, for a softer fabric 8, the pressure can be appropriately reduced to avoid excessive squeezing and damaging the fabric 8; while for a multi-layer or thicker fabric 8, the pressure may need to be increased to ensure that each layer of fabric 8 can be tightly compounded. When the fabric 8 enters between the upper and lower rollers, the rollers squeeze the fabric 8 under the set pressure, and the fibers of the fabric 8 are intertwined and fitted together under pressure, thereby achieving compounding. In this process, the rollers are pressed at a certain pressure. The rotation speed drives the fabric 8 to move forward at a uniform speed to ensure that the entire fabric 8 can be evenly subjected to pressure. The operator needs to closely observe the state of the fabric 8 during the rolling process to check whether there are bubbles, wrinkles or delamination of the fabric 8. If a heating device is used in the composite process, the composite fabric 8 needs to be cooled to achieve the ideal performance and shape. Usually, a cooling roller is used for cooling. Cooling water or air cooling is used inside the cooling roller. For water-cooled cooling rollers, the flow rate and temperature of the cooling water need to be controlled to ensure uniform cooling effect. The cooled composite fabric 8 is pulled out of the rolling area by the traction roller. The rotation speed of the traction roller needs to match the previous rolling and cooling speed to ensure the smooth transportation of the fabric 8. There needs to be enough friction between the traction roller and the fabric 8 to prevent the fabric 8 from slipping during the traction process. The composite fabric 8 is pulled to the receiving component 2 for winding. The tension control system of the receiving component 2 will adjust the tension according to the characteristics of the fabric 8 and the winding requirements, so that the fabric 8 can be tightly and smoothly wound on the winding shaft. During the winding process, care should be taken to avoid wrinkles, looseness or uneven edges of the fabric 8 to ensure good winding quality.

[0047] During the rolling and compounding process of the knee pad fabric 8, the fibers of the fabric 8 itself may produce debris due to friction, loose cutting edges, etc. If these fiber debris remain on the fabric 8, it will affect the compounding quality. The fibers of the knee pad fabric 8 may fall off due to pressure and friction, especially when the fabric 8 is made of natural fibers, such as cotton, linen, or chemical fibers and polyester fibers that are easy to fuzz. This situation is more common. When the rolling component 6 performs rolling and compounding work on the fabric 8, the suction mechanism 53 is turned on to effectively suck away these fiber debris through the suction mechanism 53 to keep the working area and the fabric 8 clean. The suction force generated by the suction mechanism 53 when working sucks impurities into the collection box 51 through the mesh plate 52, so that the impurities fall on the baffle 54 for collection. At the same time, the flocculent dust that follows the impurities into the collection box 51 is grabbed by turning on the rotating mechanism 55;

[0048] By turning on the motor 551, the output end of the motor 551 drives the lower fixing plate 553 to rotate through the rotating shaft 552, and at the same time, the lower fixing plate 553 drives the grabbing assembly 554 to rotate in the inner cavity of the collection box 51, so as to grab the flocculent dust entering the collection box 51;

[0049] When the output end of the motor 551 drives the lower fixing plate 553 to rotate through the rotating shaft 552, the lower fixing plate 553 drives the grabbing rod 5541 and the connecting plate 5542 to rotate on the baffle 54, so that the connecting shaft 5543 drives the grabbing plate 5544 to separate from the inner side of the connecting plate 5542 through the action of centrifugal force. At the same time, by evenly opening the grabbing grooves 5546 on the side of the grabbing plate 5544, the flocculent dust entering the collection box 51 can be grabbed, so as to prevent the flocculent dust and the fallen fabric flocs from floating when entering the collection box 51, thereby interfering with the collection work.

[0050] If glue is used to enhance the adhesion between fabrics 8 during the rolling and laminating process, glue may remain on the roller. When glue is squeezed out from between fabrics 8 or applied unevenly, the roller will be stained with glue during rotation. The glue residue will make the surface of the roller sticky. Over time, these residues may solidify, resulting in an uneven roller surface, which will not only affect the flatness and laminating quality of fabric 8, but may also cause abnormal conditions such as adhesion and pulling of fabric 8 on the roller, and even damage fabric 8. When the rolling component 6 is performing rolling work, when the roller in the rolling component 6 contacts and rotates with the contact shell 91, A bent plate 93 is provided on the inner side of the contact shell 91, so that the bent plate 93 can scrape off the solidified glue on the roller shaft. At the same time, a roller 94 is provided on the other side of the bent plate 93. After the bent plate 93 scrapes and cleans the side of the roller shaft, the roller 94 can contact and rotate the side of the roller shaft, so as to clean and wipe the side of the roller shaft. At the same time, when cleaning the roller shaft, the suction machine 92 is turned on and the suction force of the suction machine 92 works, so that the ejection mechanism 96 moves upward, so that the impurities scraped off by the bent plate 93 can enter the inner side of the contact shell 91 through the blanking hole 97 for collection.

[0051] When the cleaning work is completed, the vacuum machine 92 is turned off and the second spring 964 is reset and stretched, so that the second spring 964 drives the movable plate 956 to move toward the blanking hole 97, so that the ejection block 963 squeezes the inner side of the blanking hole 97, thereby avoiding impurities from clogging the blanking hole 97, thereby causing the impurities to clog the blanking hole 97. At the same time, the movable plate 956 is continuously reset and stretched by the second spring 964, so that the ejection rod 961 drives the ejection plate 962 to resist the inner side of the blanking hole 97, thereby avoiding the impurities collected in the contact shell 91 from falling.
