[0021] To further illustrate the various embodiments, the present invention provides accompanying drawings. These drawings are part of the disclosure of the present invention and are mainly used to illustrate the embodiments, and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these drawings, those skilled in the art should be able to understand other possible implementations and the advantages of the present invention. The components in the drawings are not drawn to scale, and similar component symbols are generally used to represent similar components.

[0022] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.

[0023] Reference Figures 1 to 3 This embodiment provides a release plate for a warp knitting machine (hereinafter referred to as the release plate). The release plate of this embodiment includes a base 1 and a release tooth seat 2 detachably connected to the base 1. The release tooth seat 2 and the base 1 are arranged vertically and are independent of each other. The upper end of the release tooth seat 2 away from the base 1 has a release tooth portion 22', and a positioning structure for positioning each other is provided between the release tooth seat 2 and the base 1.

[0024] In this embodiment, as Figure 1 As shown, the specific positioning structure includes a first step surface 211 and a second step surface 11 that cooperate with each other. The first step surface 211 is provided at the lower end of the disengaging tooth seat 2 facing the base 1, and the second step surface 11 is provided at the upper end of the base 1 facing the disengaging tooth seat 2. The first step surface 211 and the second step surface 11 abut against each other to ensure that the relative installation position between the disengaging tooth seat 2 and the base 1 can be accurately positioned.

[0025] like Figure 2 As shown, the base 1 and the release tooth seat 2 are detachably connected by fasteners 4. The base 1 has multiple threaded holes 12, and the release tooth seat 2 has multiple countersunk holes 212 with mating threaded holes 12. The fasteners 4 pass through the countersunk holes 212 and are screwed into the threaded holes 12 to assemble the base 1 and the release tooth seat 2 into one unit. Specifically, the fasteners 4 are countersunk screws. Since the head of the countersunk screw does not protrude from the countersunk hole 212, the overall appearance can be maintained after assembling the individual parts. Of course, in other embodiments, the fasteners 4 can also be pin screws.

[0026] By detachably connecting the disengaging gear seat 2 to the base 1 to form a split structure, the easily damaged or worn disengaging gear seat 2 can be replaced separately, which can significantly reduce the cost of use and the maintenance time.

[0027] In another preferred embodiment, the base 1 is a carbon fiber base, and the release tooth seat 2 is a metal release tooth seat, such as steel, composite material or other alloy material.

[0028] In this embodiment, the base 1 is made of carbon fiber with a low coefficient of thermal expansion, and the release tooth seat 2 is made of metal such as steel. This reduces the adverse effects of external temperature changes on the dimensions of the release plate, thereby ensuring good stability of the dimensions of the release plate.

[0029] Further preferred, such as Figure 1 and Figure 3As shown, the release tooth holder 2 includes a long strip-shaped base 21 and a plurality of toothed pieces 22 arranged at a horizontal distance and assembled on the base 21. The base 21 is assembled to the base 1 by fasteners 4. At this time, the plurality of toothed pieces 22 together constitute the release tooth portion 22' of the release tooth holder 2. Specifically, the base 21 is an aluminum alloy base, the toothed pieces 22 are steel toothed pieces, and the base 21 is provided with a first stepped surface 211 and a countersunk hole 212.

[0030] In practice, each toothed piece 22 is processed by a stamping die, and a steel plate of appropriate thickness can be selected (the thickness of the steel plate is determined by the number of needles). Therefore, compared with the cutting processing method used in the prior art, this embodiment can significantly reduce the processing difficulty and improve the processing efficiency, and the burrs and other defects on the surface of the stamped toothed piece 22 are also relatively few.

[0031] After the toothed body 22 is processed, the distance between each toothed body 22 is determined by the pin pitch. Each toothed body 22 is accurately arranged in the casting mold of the release tooth seat according to the pin pitch. Then, multiple toothed bodies 22 are integrally formed on the base 21 by the aluminum alloy integral casting process to produce the release tooth seat 2.

[0032] In another preferred embodiment, such as Figure 1 and Figure 2 As shown, a detachable protective plate 3 is provided between the release tooth seat 2 and the base 1. The protective plate 3 is used to protect the side of the release tooth 22'. The protective plate 3 has multiple relief grooves 31 for the threaded holes 12 of the base 1, so that the protective plate 3 can also be installed on the base 1. This can prevent the yarn and cloth from causing wear to the side wall of the release tooth 22' during production, and also facilitate further disassembly and assembly of various components.

[0033] Under the fastening force of the fastener 4, the guard plate 3 is attached to the back of the toothed body 22 of the disengaged tooth seat 2, and the relief groove 31 is rectangular to facilitate the adjustment of the high and low installation position of the guard plate 3.

[0034] Further preferred, such as Figure 1 As shown, the release tooth holder 2 is provided with multiple horizontally spaced grooves 13 that penetrate its inner and outer surfaces. Each groove 13 is configured to start from the lower end face of the release tooth holder 2 toward the base 1 and extend vertically upward toward the release tooth portion 22'. The grooves 13 and the release tooth portion 22' are vertically spaced to ensure that the various segments of the release tooth holder 2 are still connected.

[0035] In this specific embodiment, by arranging multiple spaced grooves 13, the lower middle part of the release tooth seat 2 is divided into several segments, and there is a certain gap between each segment. Each segment is fixed on a carbon fiber base. Since the base 1 with a low coefficient of thermal expansion is not easily affected by temperature changes, this embodiment can improve the dimensional accuracy of the release plate and reduce the probability of uneven deformation caused by thermal expansion and contraction. This ensures the consistency of the working gap between the release plate and each coiling component, that is, ensures good consistency between the width of the needle groove on the needle bed and the needle spacing.

[0036] Further preferred, such as Figure 1 As shown, the outer wall of the base 1 is provided with a plurality of mounting slots 14 arranged at intervals, which are used to assemble the base 1 onto the frame of the warp knitting machine. The mounting slots 14 are square slots, which can reduce the processing time of the base 1 and ensure the overall rigidity.

[0037] Although the present invention has been specifically shown and described in conjunction with preferred embodiments, those skilled in the art should understand that various changes in form and detail may be made to the present invention without departing from the spirit and scope of the present invention as defined in the appended claims, and all such changes shall be within the scope of protection of the present invention.
