Description

Technical Field

[0001] This utility model relates to the field of pan head technology, and in particular to a pan head connection structure. Background Technology

[0002] In warp knitting, for a long coil head assembly driven by a single power source, there are multiple long coil heads connected in sequence. Adjacent long coil heads are locked together by cladding blocks. It is necessary to ensure that the center points of all long coil heads are aligned with each other. However, since these long coil heads are usually heavy, it is usually difficult to align the center points effectively. Misalignment of the center points can cause technical problems such as motor damage, affecting synchronous wire feeding, damage to the connection parts between long coil heads, and the inability to effectively transmit the output force to the long coil head far away from the power source. Therefore, the applicant has improved the connection structure between adjacent long coil heads. Utility Model Content

[0034] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments:

[0035] Example 1:

[0036] See Figures 1-14 A pan head connection structure includes a first connector 1 and an intermediate component 2 assembled on the first connector 1. The first connector 1 is used to install on one end of the pan head 3. The outer end of the assembly of the first connector 1 and the intermediate component 2 is used to cooperate with the second connector 4 to lock the outer end of the assembly. The second connector 4 is installed on the end of another pan head to realize the connection between two adjacent pan heads.

[0037] In one implementation, for multiple pan heads using the same power source, the first pan head is connected to the power source at one end, and has a first connecting member 1 and an intermediate member 2 integrated at the other end; the second pan head has a second connecting member 4 at one end for connecting to the first pan head, and its other end also has a first connecting member 1 and an intermediate member 2 integrated; the last pan head only needs to have a second connecting member 4 at one end to connect to its adjacent pan head. The specific number of pan heads is selected according to actual needs and the driving force of the corresponding power source.

[0038] For the intermediate component 2, it includes an inner ring 21, an outer ring 22, and a plurality of spokes 23 arranged between the inner ring 21 and the outer ring 22, such as Figure 1-3 As shown.

[0039] The inner ring 21 can have various shapes. In this embodiment, the inner ring 21 is circular and has an axially extending extension 211 on its inner end face. The outer diameter of the extension 211 is smaller than the outer diameter of the main body of the inner ring. The inner ring 21 has a through hole 212 (including the extension) for fasteners to pass through. The through hole 212 includes a first hole 2121 for cooperating with the fastener rod and a second hole 2122 for cooperating with the fastener cap. The second hole 2122 is located at the outer end of the inner ring 21. The diameter of the second hole 2122 is larger than the diameter of the first hole 2121, and the two are interconnected.

[0040] As one option for the outer ring 22, its outer wall is circular and the whole is ring-shaped. In this embodiment, the inner ring 21 is arranged relatively outward in the axial direction so that the spokes 23 connected to it are also arranged outward, thereby forming a space on one side of the inner end of the outer ring 22 to avoid the corresponding components on the first connector 1, so that the intermediate part 2 is reliably connected to the first connector 1.

[0041] The first connector 1 includes a central region 11 for accommodating at least a portion of the inner ring 21 and a plurality of grooves 12 for accommodating the spokes 23. The grooves 12 are in fluid communication with the central region 11. The number of grooves 12 corresponds to the number of spokes 23, and the specific number can be selected as needed, such as six evenly arranged circumferentially. Figure 4 As shown, it can also be understood that multiple blocks are arranged circumferentially in the first connector 1, such as... Figure 4 The bumps of the pattern shown form a groove 12 for accommodating the spokes 23 between two adjacent bumps, and a central region 11 for accommodating at least a portion of the inner ring 21 is formed in the area not reached by the front end of the bump.

[0042] In this embodiment, the central region 11 includes an inner groove 111 for cooperating with the extension portion 211 of the inner ring 21, so as to improve the assembly effect between the intermediate part 2 and the first connector 1. As one embodiment, the shape of the inner groove 111 and the shape of the extension portion 211 can both be circular.

[0043] In this embodiment, preferably, the entire material of the intermediate component 2 is a deformable material, such as spring steel. Of course, it is also possible to use spring steel only in some parts of the intermediate component 2, but the actual effect will be worse than the form in which the entire material is spring steel.

[0044] In this embodiment, the intermediate component 2 is axially positioned on the first connecting component 1 by fasteners passing through the through holes, such as... Figure 9 As shown. After several disc heads are connected by the above structure and the power source is started, the intermediate component 2 needs to have a space for movement in the radial direction. Combined with the characteristics of its deformable material, this helps the center points of multiple disc heads to self-align. Specifically, gaps are left between the outer wall of the central region 11 and the outer wall of the inner ring 21 and / or between the side wall of the groove 12 and the side wall of the spoke 23. The gaps do not need to be too large, just enough to allow the intermediate component 2 to have room for movement.

[0045] In one embodiment, a gap is also left between the inner groove 111 and the extension portion 211, and the extension portion 211, the inner ring 21 and the outer ring 22 are all concentrically arranged.

[0046] like Figure 8 , Figure 12 , Figure 13 As shown, the shaft portion of the inner end of the first connector 1 passes through the flange 31 of the pan head 3, specifically by inserting it from the outer end of the flange 31, and then positioning the first connector 1 as a whole at the outer end of the flange 31 by fasteners or pins.

[0047] The intermediate component 2 is specifically assembled on the outer end of the first connector 1, and the component that cooperates with the second connector 4 is the combination of the intermediate component 2 and the outer end of the first connector 1.

[0048] In one embodiment, the outer wall of the outer end of the first connector 1, the inner wall and the outer wall of the outer ring 22 are all circular, and the cavity 43 that mates with the second connector 4 is also circular.

[0049] For the second connector 4, such as Figure 10 , Figure 11 , Figure 14 As shown, it includes a first part 41 and a second part 42 assembled on the first part 41. The shaft at the inner end of the first part 41 passes through the flange 31 of the pan head 3, specifically inserted from the outer end of the flange 31. Then, the second connector 4 is positioned as a whole at the outer end of the flange 31 by fasteners or pins.

[0050] The first part 41 has a semi-circular protruding part 411 at its outer end, and the second part 42 is a semi-circular component that matches the semi-circular protruding part 411. After assembly, it is as follows: Figure 10 As shown, the circular cavity 43 formed after assembly is used to accommodate the overall component after the intermediate part 2 and the outer end of the first connector 1 are combined, and the second part 42 can be locked by fasteners inserted thereon.

[0051] After the overall component, after being assembled with the outer end of the intermediate part 2 and the first connecting part 1, is installed in the cavity 43, it can be locked by fasteners passing through the second part 42. Although it is locked, the deformability of the spring steel material and the designed gap layout allow the pan head to automatically align with the center point when driven by the power source. This prevents problems such as damage to the power source, impact on synchronous wire feeding, wear and damage to the connection parts between adjacent pan heads, and failure to transmit power to the rear pans due to misalignment of the center point.

[0052] Example 2:

[0053] Compared with Embodiment 1, the difference lies in that at least a portion of at least one of the components of the first connecting member 1, the intermediate member 2, and the second connecting member 4 is made of a deformable material, such as spring steel. The rest of the structure is consistent with Embodiment 1.

[0054] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
