Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of textile engineering, in particular to a lifting type needle bed base of a flat knitting machine. Background Art
[0002] A flat knitting machine is a machine used to weave knitted fabrics. It forms fabric by weaving yarn into coils and interlacing the coils. Its working principle is based on the basic knitting stitches, and it mainly uses the movement of the knitting needles to achieve weaving. In the clothing manufacturing industry, flat knitting machines are key equipment for producing various types of knitted garments. They can produce a variety of garments from simple T-shirts and vests to complex sweaters and cardigans. For garments made of materials such as wool and cashmere, flat knitting machines can give full play to their weaving advantages and ensure the quality and comfort of the fabric.
[0003] During the use of knitting machines, the needle bed base plays a key role in supporting the knitting needles and providing a stable movement foundation for the knitting machine. However, the traditional lifting type needle bed base of knitting machines has exposed many defects in actual applications, among which the problem of unstable lifting is particularly prominent.
[0004] The structural design of the traditional base is often relatively simple. In terms of the lifting transmission mechanism, it is mostly transmitted through a screw nut. However, due to the limited processing accuracy of the screw, the roughness of its thread surface and pitch error and other factors, it is easy to cause jamming and vibration during the lifting process, making it impossible for the needle bed base to achieve smooth linear lifting motion. Moreover, during long-term use, due to uneven wear, this transmission instability will become more and more severe, thereby reducing the product yield, and also generating a lot of noise, causing interference to the working environment, while also increasing the maintenance cost and downtime of the equipment, greatly limiting the further development of knitting machines in efficient and high-precision production. Utility Model Content
[0005] In order to make up for the above shortcomings, the utility model provides a lifting type knitting machine needle bed base, which aims to improve the lifting transmission mechanism of the traditional lifting type knitting machine needle bed base, which is mostly transmitted through a screw nut, resulting in jamming and vibration during the lifting process, thereby reducing the product yield.

[0015] 1. In the utility model, the support plate is driven to move by the hydraulic push rod, and then the connection auxiliary device below it is driven to move. The connection auxiliary device and the hinge block are rotated together, so that the hinge block can drive the slider below it to slide along the slide rail surface, thereby providing auxiliary support and guidance for the lifting and lowering of the support plate. The sliding cooperation between the guide column and the guide hole further ensures that the support plate will not deviate during lifting, thereby ensuring the stability of the entire lifting process, effectively avoiding the jamming and vibration caused by machining accuracy problems of traditional screw and nut transmission, helping to improve the yield rate of the product, and at the same time reducing the wear on the equipment caused by unstable lifting, thereby extending the service life of the equipment.

Obviously, the embodiments described are only 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 making creative efforts are within the scope of protection of the present invention.
[0024] Reference Figure 1 - Figure 3 When the needle bed of the knitting machine is lifted up, the lifting device 11 is lifted and lowered, and the lifting and lowering of the needle bed 2 are adjusted. 5 is rotatably connected with a connection auxiliary device 6, the upper surface of the connection auxiliary device 6 is fixedly connected to the lower surface of the support plate 8, the base 1 is fixedly connected with a hydraulic push rod 7, the output end of the hydraulic push rod 7 is fixedly connected to the lower surface of the support plate 8, and a guide assembly is provided inside the support plate 8. The guide assembly is used to ensure the stability of the base 1 during lifting. At the same time, during the lifting process of the support plate 8, the guide column 10 inside the base 1 will slide in the guide hole 9 inside the support plate 8. The sliding cooperation between the guide column 10 and the guide hole 9 further ensures that the support plate 8 will not deviate during lifting, thereby ensuring the stability of the entire lifting process, effectively avoiding the jamming and vibration caused by the processing accuracy problems of the traditional screw and nut transmission, and avoiding the transmission instability problem caused by uneven wear of the screw and nut transmission, thereby reducing the maintenance frequency and cost of the equipment. The guide assembly includes a guide hole 9, which is opened inside the support plate 8. The inner wall of the base 1 is fixedly connected with the guide column 10, and the outer wall of the guide column 10 is slidably connected to the inner wall of the guide hole 9.
[0025] Reference Figure 2 - Figure 4, a card slot 12 is provided inside the needle bed body 2, and a docking slot 11 is provided inside the support plate 8. The inner wall of the docking slot 11 is slidably connected to the outer wall of the needle bed body 2. When the needle bed body 2 is installed on the base 1, the lower surface of the needle bed body 2 is first docked with the docking slot 11 inside the support plate 8. As the needle bed is placed, the card slot 12 inside the needle bed will squeeze the card strip 14 inside the card box 13, so that the card strip 14 moves into the card box 13. At the same time, the spring 15 will also be squeezed and contracted, so that the card strip 14 has a tendency to be engaged with the card slot 12 until the needle bed is completely placed in the docking slot 11, and then the elastic action of the spring 15 makes the card strip 14 able to be completely engaged with the card slot 12, that is, the fixation of the needle bed is realized, thereby ensuring the stability of the needle bed during operation. A groove 16 is provided inside the support plate 8, and a card slot 16 is provided inside the support plate 8. The connecting assembly is used to ensure the stability of the needle bed body 2 during operation. The connecting assembly includes a connecting box 13. The outer wall of the connecting box 13 is slidably connected to the inside of the support plate 8. A card strip 14 is provided inside the connecting box 13. One side of the outer wall of the card strip 14 is fixedly connected to a connecting rod 17. The outer wall of the connecting rod 17 is sleeved with a spring 15. The outer wall of the spring 15 is fixedly connected to a limiting plate 18. One side of the outer wall of the limiting plate 18 is fixedly connected to a handle 19. One end of the spring 15 is fixedly connected to the inner wall of the connecting box 13, and the other end of the spring 15 is fixedly connected to one side of the outer wall of the card strip 14. The card strip 14 is clamped with the card slot 12. When the needle bed body 2 needs to be disassembled, pull the handle 19, and the handle 19 drives the limiting plate 18 to move outward. The limiting plate 18 drives the card strip 14 to move out of the card slot 12 through the connecting rod 17, thereby releasing the lock on the needle bed.
[0026] When the knitting machine is in a state of stability, the guide post 10 on the inner wall of the base 1 will slide in the guide hole 9 on the inner wall of the base 1, and the sliding fit between the guide post 10 and the guide hole 9 will further ensure that the support plate 8 will not deviate during the lifting process, thereby ensuring the stability of the entire lifting process, effectively avoiding the jamming and vibration caused by the processing accuracy problem of the traditional screw nut transmission, and avoiding the transmission instability problem caused by uneven wear of the screw nut transmission, thereby reducing the maintenance frequency and cost of the equipment.
[0027] When installing the needle bed body 2 on the base 1, first dock the lower surface of the needle bed body 2 with the docking groove 11 inside the support plate 8. As the needle bed is placed, the slot 12 inside the needle bed will squeeze the card strip 14 inside the card box 13, causing the card strip 14 to move into the card box 13. At the same time, the spring 15 will also be squeezed and contracted, causing the card strip 14 to tend to be engaged with the slot 12 until the needle bed is completely placed in the docking groove 11. Then, through the elastic action of the spring 15, the card strip 14 can be completely engaged with the slot 12, thereby achieving the fixation of the needle bed, thereby ensuring the stability of the needle bed during operation. When the needle bed body 2 needs to be disassembled, pull the handle 19, and the handle 19 drives the limit plate 18 to move outward. The limit plate 18 drives the card strip 14 to move out of the slot 12 through the connecting rod 17, thereby releasing the lock on the needle bed.
