Description

Technical Field

[0001] This utility model belongs to the technical field of jacquard knitting machines, specifically relating to a feed roller for a jacquard knitting machine. Background Technology

[0002] A jacquard knitting machine is a specialized knitting device capable of weaving complex patterns and textures. Through precise control of needle movement, it creates patterns, designs, or three-dimensional structures on the fabric surface. Its core lies in the design of the jacquard mechanism, which surpasses the single weaving method of ordinary knitting machines, achieving diverse knitting effects. The feed roller of a jacquard knitting machine is a crucial component in the knitting process, primarily responsible for feeding the yarn evenly and stably into the knitting area, ensuring fabric quality and production efficiency. Existing jacquard knitting machine feed rollers accumulate dust or fiber debris on their surface after long-term yarn feeding. Furthermore, due to the lack of a structure for cleaning during synchronous feeding, cleaning can only be performed when the feeding operation stops. Therefore, we propose a new feed roller design for jacquard knitting machines. Utility Model Content

[0017] 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.

[0018] Please see Figures 1 to 3 This utility model provides a technical solution: a feed roller of a jacquard knitting machine, including feed rollers 2 symmetrically connected to the inner side of the drive seat 1, with adjustable cleaning mechanisms respectively provided at the ends of the two feed rollers 2, and a friction-increasing mechanism provided on the surface of the feed rollers 2. The adjustable cleaning mechanism includes a cleaning component and a lockable adjustment component.

[0019] In this embodiment, preferably, the cleaning assembly includes a fixing plate 100 symmetrically arranged at the ends of the two feed rollers 2, and a cleaning brush 101 is fixed to the inner end of the fixing plate 100 to facilitate cleaning the surface of the feed rollers 2.

[0020] In this embodiment, preferably, the lockable adjustment component includes lifting holes 200 symmetrically opened at both ends of the fixed plate 100 and fixed lifting rods 201 symmetrically fixed at the ends of the drive seat 1. The fixed lifting rods 201 are slidably connected to the lifting holes 200, so that the height of the fixed plate 100 can be adjusted.

[0021] In this embodiment, preferably, a through groove 300 is provided on the surface of the fixed lifting rod 201, and a fixing block 301 is fixed inside the lifting hole 200, with the fixing block 301 slidably connected to the through groove 300.

[0022] In this embodiment, preferably, a tension spring 400 is connected between the bottom end of the fixing block 301 and the inner bottom end of the through groove 300, which facilitates the cleaning brush 101 to make adaptive adjustments.

[0023] In this embodiment, preferably, a locking hole 500 is provided through one side of the inner wall of the lifting hole 200, and locking rods 501 are provided at both ends of the fixing plate 100 to be screwed into the locking hole 500, which can position the fixing plate 100.

[0024] In this embodiment, preferably, the friction-increasing mechanism includes a rubber ring 600 sleeved and fixed on the surface of the feed roller 2, which can allow the yarn to be fed stably.

[0025] The working principle and usage process of this utility model are as follows: When it is necessary to adjust the angle of the sweeping brush 101, first loosen the locking rod 501 to separate it from the side of the fixed lifting rod 201, and retract it into the locking hole 500 to release its positioning. Then, pull the fixing plate 100 to adjust its position, so that the lifting hole 200 slides on the surface of the fixed lifting rod 201 to move, while simultaneously driving the through groove 300 to slide on the surface of the fixing block 301 to stretch the tension spring 400. After the sweeping brush 101 is adjusted to the appropriate position, tighten the locking rod 501 again to allow it to move from the side of the fixed lifting rod 201. The adjustment can be completed by screwing the locking hole 500 inside out and pressing it against the side of the fixed lifting rod 201. Alternatively, the feeding roller 2 can be started directly. When the feeding roller 2 rotates, it can rub against the cleaning brush 101. Under the action of the tension spring 400, the fixed plate 100 can adjust its position adaptively to clean the dust, yarn debris, and fly waste on the surface of the feeding roller 2, thereby keeping the surface of the feeding roller 2 clean. Furthermore, the rubber ring 600 on the surface of the feeding roller 2 can increase the friction with the yarn, thereby better controlling the yarn conveying.

[0026] Although embodiments of the present invention have been shown and described (see the detailed description above), 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.
