Description

Technical Field

[0001] This utility model relates to the field of flat knitting machine parts technology, specifically to a computer flat knitting machine brush. Background Technology

[0002] As the core working component of a computerized flat knitting machine, the working state of the knitting needle directly affects the quality of the fabric and production efficiency. The needle latch is a key structure for loop formation and transfer. During the weaving process, the needle latch needs to open and close accurately according to a preset sequence: when the needle rises to hook new yarn, the needle latch needs to open to receive the yarn; when the needle descends, the needle latch needs to close to weave the yarn into a loop. If the needle latch fails to open properly at the required time, the yarn cannot be effectively hooked, leading to weaving accidents such as missed stitches, uneven stitches, and broken yarn. This not only affects the appearance and quality of the fabric but may also cause equipment downtime, increasing production costs and rework rates.

[0003] To ensure the stability of the needle latch during operation, computerized flat knitting machines are typically equipped with brush assemblies. The main function of the brush is to assist the needle latch in maintaining the correct posture during needle movement, ensuring it can open or close smoothly when needed. In existing computerized flat knitting machine brushes, the end that contacts the needle often uses a flush design, meaning the brush bristles form a flat contact surface. This flush brush only contacts the needle latch through its flat end face. When the needle inserts into the brush along its working path, if the latch fails to open smoothly upon contact with the brush end face for some reason, it will remain closed due to the lack of subsequent guiding or pushing structures at the brush end. In this case, the needle cannot properly hook the yarn, inevitably leading to a malfunction in the weaving process and severely affecting the continuity and stability of production. Therefore, this invention provides a brush for computerized flat knitting machines. Utility Model Content

[0004] The purpose of this invention is to provide a brush for a computerized flat knitting machine.

[0005] To solve the above-mentioned technical problems, the purpose of this utility model is achieved as follows:

[0006] A computerized flat knitting machine brush includes: a bristle section composed of a plurality of bristles, wherein the first surface of the bristle section has a stepped structure, the first end has a brush seat for fixing the bristles, and the second end has an inclined structure.

[0007] The brush holder includes an inner fixing piece that is fixedly pressed against the first end of the bristle portion and an outer fixing piece that is sleeved outside the inner fixing piece. The inner fixing piece and / or the outer fixing piece have a plurality of inwardly recessed pressure points.

[0008] Based on the above scheme and as a preferred embodiment of the above scheme, the second end of the bristle portion is inclined toward its first surface.

[0009] Based on the above scheme and as a preferred embodiment of the above scheme, the second end portion of the bristle section has a flush structure.

[0010] Based on the above scheme and as a preferred embodiment of the above scheme, the horizontal length of the inclined structure at the second end of the bristle part is equal to the unit step length of the stepped structure.

[0011] Based on the above scheme and as a preferred embodiment of the above scheme, both the internal fixation patch and the external fixation patch are made of metal.

[0012] Based on the above scheme and as a preferred embodiment of the above scheme, a number of the pressure points are evenly distributed along the length direction of the inner fixation patch and the outer fixation patch.

[0013] Compared with the prior art, this utility model has the following advantages and beneficial effects: The brush bristles of this utility model have an inclined end structure, which increases the contact area with the needle tongue compared with the existing planar structure brush. When the needle is inserted into the brush bristles, due to the existence of the inclined surface, the ends of some bristles can contact the needle tongue and open the needle tongue, reducing the probability of the needle tongue not opening, thereby avoiding manufacturing defects. At the same time, the brush holder of this application includes extruded pressure points, which improves the anti-shedding force of the bristles on the basis of the inner and outer fixing plates, effectively preventing the bristles from falling off and extending the service life of the brush.

[0018] To enable those skilled in the art to better understand the technical solution of this utility model, the preferred embodiments of this utility model are described below in conjunction with specific examples. However, it should be understood that the accompanying drawings are for illustrative purposes only and should not be construed as limiting this patent. For better illustration of this embodiment, some components in the drawings may be omitted, enlarged, or reduced, and do not represent the actual product dimensions. It is understandable that some well-known structures and their descriptions may be omitted in the drawings for those skilled in the art. The positional relationships described in the drawings are for illustrative purposes only and should not be construed as limiting this patent.

[0019] like Figures 1 to 3 As shown, a computerized flat knitting machine brush includes: a bristle section composed of several bristles 1 and a brush base for fixing the bristles.

[0020] The first side of the brush bristles has a stepped structure, while the second end has an inclined structure. The stepped structure is composed of brush filaments of different lengths arranged together, and its function is to prevent the bristles from curling up. The inclined structure is made by cutting the brush end at an angle, so that the end of the brush that contacts the needle latch is inclined, increasing the contact area with the needle latch and reducing the probability of the needle latch not opening.

[0021] Preferably, the inclined structure at the second end of the bristle portion is inclined toward its first surface, and the horizontal length of the inclined structure is equal to the unit step length of the stepped structure. Simultaneously, the second end of the bristle portion has a partially flat structure, i.e., partly inclined and partly flat.

[0022] The brush holder includes an inner fixing piece 2 fixedly pressed against the first end of the bristle portion and an outer fixing piece 3 sleeved outside the inner fixing piece 2. The inner fixing piece 2 and / or the outer fixing piece 3 have several inwardly recessed pressure points 4. In this embodiment, only the outer fixing piece 3 has pressure points 4. On the one hand, the pressure points 4 are clearly visible, making it easy for customers to know that the brush has a higher anti-shedding force. On the other hand, the pressure points 4 acting on the outer fixing piece 3 can compress the inner fixing piece 2, ensuring the anti-shedding effect of the bristles while saving production costs.

[0023] Preferably, a number of pressure points 4 are evenly distributed along the length of the outer fixing piece 3 to ensure uniform force distribution and improve the anti-detachment effect of the brush bristles 1. Both sides of the outer fixing piece 3 have pressure points 4, which are correspondingly positioned and formed by mechanical stamping and interlocking. The pressure points 4 are concave inward, squeezing the inner fixing piece 2 and the brush bristles 1, thereby improving the fixing effect of the brush bristles 1.

[0024] Both the inner fixing piece 2 and the outer fixing piece 3 are made of metal. The inner fixing piece 2 is pressed and fixed to the first end of the bristle section, serving as the main fixing component. The outer fixing piece 3 is fixed to the outside of the inner fixing piece 2, serving to strengthen the fixation and improve the appearance.

[0025] The preferred embodiments of this utility model have been described in detail above. It should be understood that those skilled in the art can make numerous modifications and variations based on the concept of this utility model without creative effort. Therefore, all technical solutions that can be obtained by those skilled in the art based on the concept of this utility model through logical analysis, reasoning, or limited experimentation on the basis of existing technology should be within the scope of protection defined by the claims.
