[0020] In order to facilitate the understanding of those skilled in the art, the present invention is further described below in conjunction with embodiments and drawings. The contents mentioned in the implementation modes are not intended to limit the present invention.

[0021] like Figures 1 to 3 As shown, the utility model provides a cage-type back-twisting machine, which includes a machine base 1, a mounting plate 2 and a support plate 3 installed on the machine base 1 in parallel and at intervals, a main shaft 4 rotatably connected between the mounting plate 2 and the support plate 3, a material changing rotation driving mechanism 5 installed on the machine base 1 or the mounting plate 2 and used to drive the main shaft 4 to rotate, a material changing disk 6 installed on the main shaft 4, an inlet nozzle 7 and an outlet nozzle 8 respectively installed at both ends of the main shaft 4, a wire passing shaft passing through the center hole of the main shaft 4 and connected with the inlet nozzle 7 and the outlet nozzle 8 respectively, a wire distribution disk 9 installed on the outlet nozzle 8, a plurality of back-twisting wire-releasing frames 10 respectively connected to the material changing disk 6, a back-twisting rotation driving mechanism 11 installed on the material changing disk 6, an outlet disk 12 sleeved on the main shaft 4 and rotatably connected to the support plate 3, a plurality of outlet limiting guide wheels 13 installed on the side of the material changing disk 6 close to the support plate 3 and a back-twisting rotation driving mechanism 11 installed on the material changing disk 6 1 and the upper and lower wire drum device 14 located below the material changing disk 6, multiple back-twisting wire-releasing frames 10, multiple outlet limiting guide wheels 13, multiple outlet holes of the outlet drum 12 and multiple branching holes of the branching disk 9 are respectively arranged one by one, and the axial direction of the wire passing shaft is provided with a wire passing hole, and the multiple branching holes of the branching disk 9 are distributed in a ring array around the wire passing hole. The back-twisting wire-releasing frame 10 is provided with an outlet channel 15 at one end close to the support plate 3, and the center line of the outlet channel 15 coincides with the rotation axis of the back-twisting wire-releasing frame 10. The outlet limiting guide wheel 13 is located at the outlet of the outlet channel 15. The back-twisting rotation drive mechanism 11 is connected to one of the back-twisting wire-releasing frames 10 in transmission connection, and the adjacent two back-twisting wire-releasing frames 10 are connected in transmission connection via the transmission assembly 16, and the direction and speed of rotation of all the back-twisting wire-releasing frames 10 are the same; the core wire passes through the inlet nozzle 7, the wire passing hole and the outlet nozzle 8 in sequence. Specifically, the upper and lower wire drum device 14 can adopt an existing device, which will not be repeated here.

[0022] In actual application, the wire drum is loaded onto each detwisting pay-off frame 10 through the upper and lower wire drum devices 14, and the wire drum can rotate relative to the detwisting pay-off frame 10 to pay off the wire. The wire released by the wire drum passes through the corresponding wire outlet channel 15, the wire outlet limit guide wheel 13, the wire outlet hole of the wire outlet drum 12 and the wire branching hole of the wire branching drum 9 in turn, and is then transported to the external twisting machine. The twisting machine twists multiple wires on the core wire moving along the wire passing hole of the wire passing shaft. In the process of the twisting machine twisting multiple wires, the detwisting rotation drive mechanism 11 drives one of the detwisting pay-off frames 10 to rotate. Under the transmission action of the transmission component 16, all the detwisting pay-off frames 10 rotate synchronously, and the rotation direction and speed are the same, so as to realize the detwisting of the wires twisted by the twisting machine. Since all the detwisting pay-off frames 10 rotate synchronously, and the rotation direction and speed are the same, the detwisting rate of all wires is consistent. In addition, when it is necessary to replace the wire reel on the back-twisting pay-off frame 10, the material-changing rotating drive mechanism 5 drives the main shaft 4 to rotate synchronously with the material-changing reel 6 and the back-twisting pay-off frame 10, so that each back-twisting pay-off frame 10 rotates to the top of the upper and lower reel devices 14 in turn, and the wire reel on the back-twisting pay-off frame 10 is replaced by the upper and lower reel devices 14, thereby improving the efficiency of replacing the wire reel and reducing the labor intensity of replacing the wire reel. The utility model has a simple structure and low cost, can realize back-twisting of wires, and the back-twisting rate of all wires is consistent, which improves the quality of subsequent twisting of the wires, and the replacement of the wire reel is convenient and efficient.

[0023] In this embodiment, the spindle 4 is equipped with an anti-jumping wire guide wheel passing disk 17, which is located on the incoming wire side of the outlet disk 12. The wire passes through the anti-jumping wire guide wheel passing disk 17, which guides and limits the wire, plays a role in guiding the wire and preventing the wire from jumping, and improves the stability of the wire movement. Specifically, the anti-jumping wire guide wheel passing disk 17 can adopt an existing structure, which will not be repeated here.

[0024] In this embodiment, two opposite side plates of the back-twisting pay-off frame 10 are relatively equipped with fixed heads 18 and movable heads 19. In practical applications, when the wire drum is located between the fixed head 18 and the movable head 19, the head block of the movable head 19 pushes the wire drum onto the head block of the fixed head 18, so that the head block of the movable head 19 cooperates with the head block of the fixed head 18 to clamp the two ends of the wire drum. When the wire drum is paid off, the head block of the fixed head 18, the wire drum and the head block of the movable head 19 can rotate synchronously.

[0025] In this embodiment, a tension mechanism 20 is installed on one side plate of the back-twisting pay-off frame 10, and the tension mechanism 20 is drivingly connected to the head block of the fixed head 18. When the wire drum and the head block of the fixed head 18 rotate synchronously to pay off the wire, the tension mechanism 20 provides appropriate tension to the head block of the fixed head 18, and under the action of the tension mechanism 20, the tension of the wire released from all the wire drums is consistent.

[0026] In this embodiment, the tension mechanism 20 includes a driven gear 21 mounted on the plug block of the fixed plug 18, a hysteresis clutch 22 installed on the back-twisting wire-releasing frame 10, and a driving gear 23 installed on the output end of the hysteresis clutch 22, and the driving gear 23 is meshed with the driven gear 21. In actual application, the hysteresis clutch 22 applies a force to the plug block of the fixed plug 18 through the meshing of the driving gear 23 and the driven gear 21, thereby applying tension to the wire drum.

[0027] In this embodiment, the other side plate of the detwisting pay-off frame 10 is equipped with a counterweight block 24, and the sum of the weight of the counterweight block 24 and the movable head 19 is equal to the sum of the weight of the tension mechanism 20 and the fixed head 18. This structural design makes the detwisting pay-off frame 10 evenly stressed, has good rotation stability, and has a good detwisting effect on the wire.

[0028] In this embodiment, the transmission assembly 16 is composed of a synchronous belt and a synchronous wheel.

[0029] All technical features in this embodiment can be freely combined according to actual needs.

[0030] The above embodiments are preferred implementation schemes of the present invention. In addition, the present invention can also be implemented in other ways. Any obvious replacement without departing from the concept of the present technical solution is within the protection scope of the present invention.
