DETAILED DESCRIPTION

[0024] The following is a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0025] Reference Figures 1 to 3 :

[0026] The cloth-stretching rack traceless device comprises a mounting seat 1, a cloth-stretching rack 2 arranged in a closed loop on the periphery of the mounting seat 1, and at least two stretching units for connecting the mounting seat 1 and the cloth-stretching rack 2. In the present embodiment, three stretching units are provided, namely, a first stretching unit 31, a second stretching unit 32, and a third stretching unit 33. The first stretching unit 31, the second stretching unit 32, and the third stretching unit 33 each include two stretching arms (respectively, a first stretching arm 311 and a second stretching arm 312). The use of three stretching units can balance the tension or pulling force on the cloth-stretching rack 2, so that the cloth-stretching rack 2 maintains a balanced structure. When the cloth-stretching rack 2 is working, the three stretching units move in coordination to ensure the stability of the overall structure of the cloth-stretching rack 2. In this way, the structure of the cloth-stretching rack 2 is reasonable, easy to use, practical and reliable, and simple to install. Of course, the present embodiment is not limited to the provision of three stretching units.

[0027] The cloth-supporting frame 2 includes a first connecting rod 23, a first cloth-supporting rod 21, a second connecting rod 24, and a second cloth-supporting rod 22 which are sequentially connected to each other, the first cloth-supporting rod 21 and the second cloth-supporting rod 22 are both retractable arc-shaped structures, the first connecting rod 23 and the second connecting rod 24 are both arc-shaped structures, and the first connecting rod 23, the first cloth-supporting rod 21, the second connecting rod 24, and the second cloth-supporting rod 22 form a closed-loop cloth-supporting frame 2. The cloth-supporting frame 2 composed of various components of various arc-shaped structures does not have large bends and folds, thereby avoiding the problem of hanging marks or wrinkles on the cloth surface caused by uneven bends or large folds.

[0028] For the convenience of description, the ends of the first and second cloth-supporting rods 21 and 22 that are sleeved with the first connecting rod 23 are defined as first ends, and the ends that are sleeved with the second connecting rod 24 are defined as second ends.

[0029] The diameter of the first connecting rod 23 is larger than the diameter of the first end of the first cloth-supporting rod 21 and the diameter of the first end of the second cloth-supporting rod 22, and the diameter of the second connecting rod 24 is larger than the diameter of the second end of the first cloth-supporting rod 21 and the diameter of the second end of the second cloth-supporting rod 22.

[0030] The first cloth-supporting rod 21 and the second cloth-supporting rod 22 each include a plurality of mutually sleeved support rods, and the diameters of two adjacent support rods are different. The support rod with a smaller diameter can be movably nested in the support rod with a larger diameter; the diameters of the plurality of support rods of the first cloth-supporting rod 21 and the diameters of the plurality of support rods of the second cloth-supporting rod 22 are successively reduced or increased from the first connecting rod 23 to the second connecting rod 24, so that the first cloth-supporting rod 21 and the second cloth-supporting rod 22 can be telescopic, so that the cloth-supporting rack 2 is suitable for cloths of different sizes. Of course, the cloth-supporting rack 2 of this embodiment can also be provided with a cloth-supporting rod surrounded by a plurality of support rods, and the diameters of the plurality of support rods are successively reduced or increased from the first end to the second end. Specifically, in this embodiment, the support rods are made of stainless steel.

[0031] Furthermore, the mounting seat 1 is penetrated by a mounting hole 11 along the axis and by at least two connecting holes parallel to the opening directions thereof along the side (in the present embodiment, three connecting holes are provided corresponding to the three extension units, namely the first connecting hole 121, the second connecting hole 122 and the third connecting hole 123). The first connecting hole 121, the second connecting hole 122 and the third connecting hole 123 are sequentially arranged at different heights of the mounting seat 1 along the axis direction of the mounting seat 1. The opening directions of the first connecting hole 121, the second connecting hole 122 and the third connecting hole 123 are parallel and cross-arranged. The opening direction of the third connecting hole 123 is located between the opening directions of the first connecting hole 121 and the second connecting hole 122. The first connecting hole 121, the second connecting hole 122 and the third connecting hole 123 are respectively vertically connected to the mounting hole 11.

[0032] Further, the present embodiment further includes an adjustment mechanism disposed on the mounting seat 1, the adjustment mechanism including a transmission rod 41 rotatably disposed on the mounting hole 11 and an adjustment member 42 driving the transmission rod 41 to rotate along the mounting hole 11. The transmission rod 41 is disposed in the mounting hole 11 and can rotate relative to the mounting seat 1. Specifically, the transmission rod 41 is provided with four sets of gears (not shown in the figure) in sequence around its circumference in the axial direction, which are respectively used to be connected with the first extension unit 31, the second extension unit 32, the third extension unit 33 and the adjustment member 42 through toothed transmission, and the four sets of gears are arranged in sequence around its circumference along the axial direction of the transmission rod 41.

[0033] Taking the first stretching unit 31 as an example, the first stretching unit 31 is arranged in the second connecting hole 122, and the first stretching arm 311 and the second stretching arm 312 of the first stretching unit 31 are respectively located on both sides of the transmission rod 41 and are respectively engaged with the transmission rod 41, and the transmission rod 41 drives the first stretching arm 311 and the second stretching arm 312 to move in opposite directions, thereby extending or contracting the cloth support frame 2.

[0034] Furthermore, racks 314 are provided on opposite side walls of the first extension arm 311 and the second extension arm 312 and are respectively meshed with the gears of the transmission rod 41 . The cross-sections of the first extension arm 311 and the second extension arm 312 are rectangular.

[0035] One end of the first extension arm 311 is connected to the first cloth-supporting rod 21, and the other end is inserted into the first connection hole 121. One end of the second extension arm 312 is connected to the second cloth-supporting rod 22, and the other end is inserted into the first connection hole 121. The first extension arm 311 and the second extension arm 312 are located on both sides of the transmission rod 41 and are transmission-connected to the transmission rod 41. The first cloth-supporting rod 21 and the second cloth-supporting rod 22 are connected through the first extension arm 311 and the second extension arm 312 of the first extension unit 31. When the transmission rod 41 drives the first extension arm 311 and the second extension arm 312 to move away from each other, the first extension arm 311 and the second extension arm 312 are unfolded, driving the first cloth-supporting rod 21 and the second cloth-supporting rod 22 to extend, so that the cloth-supporting frame 2 is opened. When the transmission rod 41 drives the first extension arm 311 and the second extension arm 312 to move toward each other, the first extension arm 311 and the second extension arm 312 are contracted, driving the first cloth-supporting rod 21 and the second cloth-supporting rod 22 to shorten, so that the cloth-supporting frame 2 is folded.

[0036] The first stretching unit 31, the second stretching unit 32, and the third stretching unit 33 can balance the tension or pulling force of the first stretching arm 311 and the second stretching arm 312 on the first cloth-stretching rod 21 and the second cloth-stretching rod 22, so that the first cloth-stretching rod 21 and the second cloth-stretching rod 22 maintain a balanced structure, and when the cloth-stretching frame 3 is working, the first cloth-stretching rod 21 and the second cloth-stretching rod 22 move in coordination to ensure the stability of the overall structure of the cloth-stretching frame 2, so that the structure of the cloth-stretching frame 2 is reasonable, easy to use, practical and reliable, and easy to install. It is worth noting that the connection relationship between the second stretching unit 32 and the third stretching unit 33 and the corresponding second connecting hole 122 and the third connecting hole 123 in this embodiment is consistent with the connection relationship between the first stretching unit 31 and the first connecting hole 121, which will not be described in detail here.

[0037] This embodiment also includes a plurality of traceless members 5 correspondingly arranged on the first stretching unit 31, the second stretching unit 32, and the third stretching unit 33. The traceless member 5 includes a first end 51 fixedly connected to the corresponding stretching unit by bolts, a second end 52 away from the corresponding stretching unit, and a connecting section 53 connecting the first end 51 and the second end 52. The connecting section 53 is an arc-shaped structure protruding outward, and the connecting section 53 covers the joint 211 between two adjacent support rods. Specifically, the first end 51 is fixedly connected to the first stretching arm 311 of the corresponding stretching unit, and the first stretching arm 311 is connected to the support rod with a larger diameter. When the cloth support frame 2 is opened or folded, the connecting section 53 of the traceless member 5 can cover the joint 211 between two adjacent support rods. Of course, if it is arranged on a support rod with a smaller diameter, it is sufficient to ensure that the stretching or contraction distance of the connected support rod is less than the lateral width of the connecting section 53, that is, the connecting section 53 of the traceless member 5 can cover the joint 211 between two adjacent support rods.

[0038] Furthermore, there are two second ends 52, and the two second ends 52 are symmetrically arranged along the first end 51. When the first end 51 is fixedly connected to the first extension arm 311 of the corresponding extension unit, and the first extension arm 311 is connected to the first connecting rod 23 (or the second connecting rod 24) with a larger diameter, when the cloth-supporting frame 2 is opened or folded, the connecting section 53 of the traceless member 5 can cover the joint 211 between the first cloth-supporting rod 21 and the first connecting rod 23 (or the second cloth-supporting rod 22 and the first connecting rod 23, the first cloth-supporting rod 21 and the second connecting rod 24, the second cloth-supporting rod 22 and the second connecting rod 24). Of course, if it is set on a support rod with a smaller diameter, it is sufficient to ensure that the extension or contraction distance of the connected support rods is less than the lateral width of the connecting section 53, that is, the connecting section 53 of the traceless member 5 can cover the joint 211.

[0039] Furthermore, two cloth guide wheels (not shown in the figure) are included, and the two cloth guide wheels are respectively arranged on the first connecting rod 23 and the second connecting rod 24. The cloth guide wheels play a role in supporting the cloth support frame 2, so that the mounting seat 1 does not contact the cloth surface when the cloth support frame 2 is working. When the cloth support frame 2 is working, the cloth guide wheels are placed on the cloth surface, and no hanging marks or wrinkles are generated on the cloth surface.

[0040] When using:

[0041] The transmission rod 51 is driven to rotate by the adjusting member 52, thereby driving the first extension arm 311 and the second extension arm 312 of the first extension unit 31, the first extension arm 311 and the second extension arm 312 of the second extension unit 32, and the first extension arm 311 and the second extension arm 312 of the third extension unit 33 to move in opposite directions. Specifically, when the transmission rod 51 is rotated to make each first extension arm 311 and the second extension arm 312 move in opposite directions, the three pairs of extension units cooperate to increase the linear distance between the cloth support frames 2, and the cloth support frames 2 are opened;

[0042] When the transmission rod 51 is driven to rotate by the adjusting member 52, thereby driving the first extending arm 311 and the second extending arm 312 of the first extending unit 31, the first extending arm 311 and the second extending arm 312 of the second extending unit 32, and the first extending arm 311 and the second extending arm 312 of the third extending unit 33 to move toward each other, the three pairs of extending units cooperate to shorten the straight-line distance between the cloth supporting frames 2, and the cloth supporting frames 2 are retracted.

[0043] By adopting the above-mentioned design scheme, the beneficial effects of the utility model are as follows: by arranging the seamless member 5 on the cloth support frame 2, the connecting section 53 of the seamless member 5 covers the joint 211 between two adjacent support rods, so as to avoid that when the grey cloth 9 passes through the joint 211 during cloth laying, the surface of the grey cloth 9 will be left with indentations, which will affect the quality of the finished garment product; at the same time, the original configuration of the cloth support frame 2 and the machine platform does not need to be changed, and it is suitable for existing circular knitting machines, saving equipment modification costs; the utility model has a reasonable structure, is easy to use, is practical and reliable, and is simple to install.

[0044] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
