Description

Technical Field

[0001] The utility model relates to the field of flat knitting machines, in particular to a straight double base for a flat knitting machine. Background Art

[0002] A computerized flat knitting machine is a fully automatic machine used to weave fabrics. It is mainly composed of a head part, a needle bed part, a frame part, an electronic control part and an appearance part. Almost all parts used for knitting functions are installed on the needle bed. Therefore, the quality and stability of the needle bed base are related to the density and aesthetic effect of all the knitted fabrics in the later stage.

[0003] When a flat knitting machine is knitting, the machine head moves back and forth horizontally. Slide rails are typically installed on the base to increase the stability of the machine head during movement. Existing needle bed slide rails are typically secured to the slide rail seat using fasteners such as screws or welding. However, after long-term use, the fixation between the slide rail and the slide rail seat can decrease, causing the slide rail to wobble. Improving the reliability of the connection between the slide rail and the slide rail seat is an ongoing research and development area. To address these issues, the following proposes a solution. Utility Model Content

[0004] The utility model aims to provide a straight double base for a flat knitting machine, which has the advantages of enhancing the connection stability between the slide rail and the slide rail seat and preventing the slide rail from shaking.

[0005] The above technical objectives of the present invention are achieved through the following technical solutions:

[0006] A straight double base for a flat knitting machine includes a base body and several slide rail seats, wherein the several slide rail seats are respectively located on both sides of the base body and are evenly distributed along the length direction of the base body. The slide rail seats and the base body are of an integrated design, and the slide rail seats are perpendicular to the side faces of the base body. Slide rails are provided on both sides of the base body, and the two slide rails are arranged parallel to the length direction of the base body, and the two slide rails are respectively located on both sides of the base body. A positioning groove is provided on the slide rail seat, and one side of the slide rail is clamped in the positioning groove and fixedly connected to the slide rail seat by fasteners.

[0007] Preferably, the slide rail is in the shape of a rectangular parallelepiped, the width of the slide rail is 20-21 mm, the height of the slide rail is 30-31 mm, the width of the positioning groove is 6-7 mm, the height of the positioning groove is 19-20 mm, the width direction of the slide rail corresponds to the width direction of the positioning groove, and the height direction of the slide rail corresponds to the height direction of the positioning groove.

[0008] Preferably, a fastening hole is provided on the slide rail seat, the fastening hole passes through the slide rail seat and communicates with the positioning groove, and the fastener passes through the fastening hole and fixes the slide rail.

[0009] Preferably, the inclined surfaces on both sides of the base body are base surfaces, the angle between the two base surfaces is 100°, and the width of the base surfaces is 155-160 mm.

[0010] Preferably, the distance between the bottom surface and the base surface of the slide rail is 38-40 mm, and the distance between the top surface and the base surface of the slide rail is 70-72 mm.

[0011] The beneficial effects of this utility model are as follows: the right-angled positioning grooves can support both sides of the slide rail and increase the contact area between the slide rail and the slide rail seat. When welded, the connection between the slide rail and the slide rail seat is more secure. The slide rail seat also has fastening holes into which fasteners such as screws can be driven. One end of the fastener is driven into the slide rail to enhance the connection between the slide rail and the slide rail seat. Alternatively, the rear side of the slide rail can be fixed to the edge of the fastening hole by welding without using screws, thereby further enhancing the connection between the slide rail and the slide rail seat.

[0015] The following is only a preferred embodiment of the present invention, and the scope of protection is not limited to this embodiment. All technical solutions under the concept of the present invention should fall within the scope of protection of the present invention. The same parts are represented by the same figure marks. It should be noted that the words "front", "rear", "left", "right", "up" and "down" used in the following description refer to the directions in the accompanying drawings, and the words "bottom" and "top", "inside" and "outside" refer to the directions toward or away from the geometric center of a specific component, respectively.

[0016] like Figure 1 and Figure 2 As shown, a straight double base for a flat knitting machine includes a base body 1 and several slide rails 2. The slide rails 2 are integrated with the base body 1. The slide rails 2 are evenly distributed on both sides of the base body 1, and the slide rails 2 on the same side are evenly distributed along the length of the base body 1. The integrated design provides a very reliable connection between the slide rails 2 and the base body 1, preventing any shaking.

[0017] The inclined surfaces on either side of the base body 1 serve as the base surfaces. In this design, the angle between the two base surfaces is 100°, and the base surface width is 155-160mm. Compared to existing base bodies 1 with a base width of 170mm-175mm, this design requires less raw material, saving costs. Combined with dedicated needle plates and other components, further cost savings can be achieved while still ensuring normal knitting.

[0018] A positioning slot 4 is provided at the end of the rail base 2 facing away from the base body 1. In this design, the positioning slot 4 is a right angle and is located diagonally upward on the side of the rail base 2. Because the rail base 2 and the side surfaces of the base body 1 are perpendicular, the underside of the positioning slot 4 is parallel to the base surface. The rail 3 is a rectangular parallelepiped. When the rail 3 is placed in the positioning slot 4, with its two side surfaces aligned with the side surfaces of the positioning slot 4, the rail 3 also remains parallel to the base surface.

[0019] In this design, the width of the slide rail 3 is 20-21 mm, the height of the slide rail 3 is 30-31 mm, the width of the positioning slot 4 is 6-7 mm, and the height of the positioning slot 4 is 19-20 mm. The width of the slide rail 3 corresponds to the width of the positioning slot 4, and the height of the slide rail 3 corresponds to the height of the positioning slot 4. Therefore, after the slide rail 3 is installed in the positioning slot 4, the positioning slot 4 can support approximately one-third of the lower end surface of the slide rail 3 and approximately two-thirds of the side surface of the slide rail 3. Therefore, when the slide rail 3 is fixed in the positioning slot 4, it can be more stable.

[0020] The slide rail 3 and the slide rail seat 2 can be fixed with fasteners such as screws. A fastening hole is provided on the slide rail seat 2. One end of the fastener can pass through the fastening hole and be nailed to the slide rail 3 to achieve fixation between the slide rail 3 and the slide rail seat 2.

[0021] Since the materials used in this design are all metal, solder can also be used as the fastener. The positioning groove 4 increases the contact area between the slide rail 3 and the slide rail seat 2, thereby increasing the welding area between the slide rail 3 and the slide rail seat 2. The fastening hole communicates with the positioning groove 4, that is, one end of the fastening hole contacts one side of the slide rail 3. Therefore, the slide rail 3 and the fastening hole can be welded to the fastening hole, enhancing the connection reliability between the slide rail 3 and the slide rail seat 2.

[0022] In this design, the distance between the bottom surface of the slide rail 3 and the base surface is 38-40 mm, and the distance between the top surface of the slide rail 3 and the base surface is 70-72 mm. This distance can minimize the length of the slide rail base 2 and reduce the production cost of the slide rail base 2 without affecting knitting.

[0023] The specific embodiments described above further illustrate the technical problems, technical solutions and beneficial effects solved by the present invention. It should be understood that the above are only specific embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
