The embodiments described below by referring to the accompanying drawings are exemplary and are intended to explain the present utility model, and should not be construed as a limitation to the present utility model.

[0020] First Embodiment:

[0021] Please refer to Figures 1 to 3 , where Figure 1 is a schematic structural diagram of the anti - chaos yarn feeding device of the first embodiment, Figure 2 is a schematic internal structure diagram of the mounting cylinder in the first embodiment, Figure 3 is Figure 2 an enlarged partial structure diagram of part A of

[0022] The present utility model provides an anti - chaos yarn feeding device: including a yarn rack 101, a plurality of fixed rods 102, a plurality of mounting cylinders 103, a plurality of fixing plates 104, a plurality of tensioning wheels 105 and a plurality of fixing mechanisms. Each of the fixing mechanisms includes a rotating shaft 106, a handwheel 107, two rotating disks 108, a plurality of sliding rods 109, a plurality of tooth seats 110 and a plurality of abutting blocks 111. Through the foregoing solution, the problem that the existing yarn feeding device does not have a mechanism for clearly fixing the yarn arranging cylinder, resulting in the yarn arranging cylinder being easily detached and dropped from the yarn rack 101, causing the yarn to be tangled and affecting the use of the circular knitting machine, is solved. It can be understood that the foregoing solution can be used in the structure of the yarn feeding device of the circular knitting machine.

[0023] For this specific embodiment, a plurality of the fixed rods 102 are fixedly arranged on the side surface of the yarn rack 101. A limit disk 112 is fixedly arranged at one end of each fixed rod 102 away from the yarn rack 101. The mounting cylinder 103 is rotatably arranged at one end of each limit disk 112 away from the corresponding fixed rod 102. A plurality of the fixing plates 104 are further arranged on the side surface of the yarn rack 101. Each fixing plate 104 is respectively located above one of the fixed rods 102. The tensioning wheel 105 is arranged on each fixing plate 104. After the yarn cylinder is installed outside the mounting cylinder 103, the yarn of the yarn cylinder is tensioned by the tensioning wheel 105 and then connected to the circular knitting machine. Through the arrangement of the tensioning wheel 105, the scattering and tangling of the yarn can be prevented, affecting production and thus improving the yarn feeding effect.

[0024] Among them, a rotating shaft 106 is rotatably arranged at one end of the installation cylinder 103 away from the corresponding limit disc 112. At one end of the rotating shaft 106 located inside the installation cylinder 103, two rotating discs 108 are arranged. The two rotating discs 108 are respectively located at both ends inside the installation cylinder 103. At one end of the rotating shaft 106 located outside the installation cylinder 103, a handwheel 107 is arranged. A planar thread 113 is arranged on each rotating disc 108. A plurality of sliding rods 109 are slidably arranged at both ends of the outer side wall of the installation cylinder 103. At one end of each sliding rod 109 located inside the installation cylinder 103, a tooth seat 110 is arranged. At one end of each sliding rod 109 located outside the installation cylinder 103, a holding block 111 is arranged. The tooth part of the tooth seat 110 meshes with the corresponding planar thread 113. When installing the yarn bobbin, after placing the yarn bobbin outside the installation cylinder 103, rotate the handwheel 107 to drive the rotating shaft 106 to rotate, thereby driving the two rotating discs 108 to rotate inside the installation cylinder 103. Since the tooth part of the tooth seat 110 meshes with the planar thread 113 on the rotating disc 108, the tooth seat 110 is driven to move on the planar thread 113, and then the sliding rod 109 is driven to slide on the side wall of the installation cylinder 103, so that the holding block 111 abuts against the inner side wall of the yarn bobbin, thereby firmly installing the yarn bobbin on the installation cylinder 103, preventing the yarn bobbin from falling off the installation cylinder 103 due to the pulling force of the circular knitting machine, resulting in chaotic winding of the yarn and affecting the use of the circular knitting machine.

[0025] Secondly, two limit rings 114 are arranged on the outside of each rotating shaft 106. The two limit rings 114 are respectively located on the inner and outer sides of the end of the corresponding installation cylinder 103. Through the arrangement of the two limit rings 114, when the rotating shaft 106 rotates at the end of the installation cylinder 103, the structure is more stable.

[0026] At the same time, a fixed wing ring 115 is arranged on each handwheel 107. After the fixed wing ring 115 is arranged on the outside of the corresponding rotating shaft 106, the fixed wing ring 115 is fixed on the outer side wall of the rotating shaft 106 to complete the installation of the handwheel 107.

[0027] In addition, an anti-slip rubber pad 116 is arranged at one end of each holding block 111 away from the corresponding sliding rod 109, and an anti-slip pattern 117 is arranged on the outside of each handwheel 107. Through the arrangement of the anti-slip rubber pad 116, the fixing effect on the yarn bobbin is better. Through the arrangement of the anti-slip pattern 117, when rotating the handwheel 107, the operation is more convenient.

[0028] When using an anti - chaos yarn feeding device of this embodiment, after installing the yarn bobbin outside the installation cylinder 103, the yarn of the yarn bobbin is tightened by the tension wheel 105 and then connected to a circular knitting machine. Through the setting of the tension wheel 105, the scattering and entanglement of the yarn can be prevented, which affects production and thus improves the yarn feeding effect. And when installing the yarn bobbin, after placing the yarn bobbin outside the installation cylinder 103, rotate the handwheel 107, drive the rotation shaft 106 to rotate, thereby driving the two rotating disks 108 to rotate inside the installation cylinder 103. Since the tooth part of the tooth seat 110 meshes with the planar thread 113 on the rotating disk 108, the tooth seat 110 is driven to move on the planar thread 113, and then the sliding rod 109 is driven to slide on the side wall of the installation cylinder 103, so that the abutting block 111 abuts against the inner side wall of the yarn bobbin, thereby firmly installing the yarn bobbin on the installation cylinder 103, preventing the yarn bobbin from falling off the installation cylinder 103 due to the pulling force of the circular knitting machine, resulting in yarn chaos and entanglement, which affects the use of the circular knitting machine.

[0029] Second Embodiment:

[0030] Based on the first embodiment, please refer to Figure 4 , Figure 4 which is a schematic diagram of the internal structure of the installation cylinder in the second embodiment.

[0031] The anti - chaos yarn feeding device provided by the present utility model further includes a plurality of auxiliary support members. Each auxiliary support member includes a support ring 201, a plurality of connecting rods 202 and a fixed arc plate 203.

[0032] For this specific embodiment, each installation cylinder 103 is internally provided with the auxiliary support member. The auxiliary support member is located between two corresponding rotating disks 108, and the auxiliary support member is arranged outside the rotating shaft 106. By using the auxiliary support member to support the rotating shaft 106, the structure is more stable when the rotating shaft 106 rotates.

[0033] Among them, the support ring 201 is arranged outside the rotating shaft 106. A plurality of connecting rods 202 are arranged outside the support ring 201. Each end of each connecting rod 202 far from the support ring 201 is provided with the fixed arc plate 203. The fixed arc plate 203 is connected to the inner side wall of the installation cylinder 103. After arranging the support ring 201 outside the rotating shaft 106, the fixed arc plate 203 is fixed on the inner side wall of the installation cylinder 103, thus completing the installation of the auxiliary support member.

[0034] When using an anti-confusion yarn feeding device according to this embodiment, after the support ring 201 is arranged outside the rotating shaft 106, the fixed arc plate 203 is fixed on the inner side wall of the mounting cylinder 103, thereby completing the installation of the auxiliary support member. The rotating shaft 106 is assisted and supported by the auxiliary support member, so that the structure of the rotating shaft 106 is more stable when it rotates.

[0035] The above-disclosed is only a preferred embodiment of the present invention, and of course, it cannot be used to limit the scope of the rights of the present invention.
