[0002] Warping machines are widely used in the textile industry to produce a variety of knitted fabrics, such as underwear, socks, and sportswear. Their efficient and stable performance and diverse product adaptability have made them a key player in the textile industry. Before weaving, the spun yarn or thread is tightly stretched and combed back and forth to form the warp or end threads. Before weaving the fabric, workers are usually required to manually lift and change the warp head. This manual lifting and changing of the warp head is time-consuming and laborious, especially when the warp head is fully loaded with warp yarn. The heavy weight of the warp head makes it even more difficult to lift and lower, making disassembly and installation difficult. It also poses certain safety risks, such as accidental falls and resulting in casualties. Utility Model Content

[0028] The present invention is described in detail below with reference to the accompanying drawings.

[0029] like Figures 1 to 4 As shown, the screw transmission mechanism of a warp machine of the present invention includes a frame 1, a lifting device 2 arranged on the frame 1, a disk head 3 placed on the lifting device 2, and a clamping device 4 used in conjunction with the lifting device 2, the lifting device 2 includes a screw assembly 21, a driver 22 driven and connected to the screw assembly 21, and a conveying assembly 23 arranged on the screw assembly 21, the driver 22 drives the conveying assembly 23 to move up and down relative to the frame 1 through the screw assembly 21, so that the disk head 3 is clamped on the clamping device 4.

[0030] During operation, the external loading mechanism first drives the disc head 3 to roll and roll along the slope set on the frame 1 to the conveying assembly 23. Then, the driver 22 drives the conveying assembly 23 upward through the screw assembly 21. When the disc head 3 rises to the position of the clamping device 4 via the conveying assembly 23, the disc head 3 is accurately installed on the clamping device 4 and the operation is started. The frame 1 is provided with a control panel, which is electrically connected to the PLC control system. The PLC control system intelligently controls the working process of the driver 22 and the clamping device 4, with a high degree of automated control, time-saving and labor-saving work, and high work accuracy. The utility model has a compact structure and a reasonable design, and can realize the automatic and smooth lifting of the disc head 3, saving time and labor in operation, saving labor costs, and improving work safety.

[0031] The screw assembly 21 of this embodiment includes a first screw member 211, a second screw member 212 spaced apart and arranged parallel to the first screw member 211, a first screw nut 213 threadedly sleeved on the outside of the first screw member 211, a second screw nut 214 threadedly sleeved on the outside of the second screw member 212, a first synchronous wheel 215 connected to the first screw member 211, a second synchronous wheel 216 and a third synchronous wheel 217 connected to the second screw member 212, and a first synchronous belt 218 driven between the first synchronous wheel 215 and the second synchronous wheel 216, the first screw nut 213 and the second screw nut 214 are both connected to the conveying assembly 23, the output end of the driver 22 is drivenly connected to the fourth synchronous wheel 219, and the second synchronous belt 2110 is connected between the third synchronous wheel 217 and the fourth synchronous wheel 219. Specifically, in actual use, the first screw rod 211 and the second screw rod 212 are respectively arranged on both sides of the frame 1. Since the first screw rod nut 213 is threadedly sleeved on the outside of the first screw rod 211 and the second screw rod nut 214 is threadedly sleeved on the outside of the second screw rod 212, the driver 22 drives the fourth synchronous wheel 219 to rotate, and the rotating fourth synchronous wheel 219 drives the third synchronous wheel 217 to rotate through the second synchronous belt 2110. Further, the rotating third synchronous wheel 217 simultaneously drives the second screw rod 212 and the second synchronous wheel 216 to rotate. On the one hand, the rotating The second screw rod 212 drives the second screw nut 214 to move up and down. On the other hand, the rotating second synchronous wheel 216 further drives the first synchronous wheel 215 to rotate through the first synchronous belt 218, so that the rotating first synchronous wheel 215 drives the first screw rod 211 to rotate, and the rotating first screw rod 211 drives the first screw nut 213 to move up and down. The first screw nut 213 and the second screw nut 214 are both connected to the conveying component 23, so that the screw component 21 drives the conveying component 23 to move up and down relative to the frame 1, with high transmission efficiency and smooth and rapid movement.

[0032] The driver 22 of this embodiment includes a reducer 221 and a servo motor 222 drivingly connected to the reducer 221. The output end of the reducer 221 is drivingly connected to the fourth synchronous gear 219. Specifically, the servo motor 222 drives the fourth synchronous gear 219 to rotate via the reducer 221. The reducer 221 can reduce the speed output by the servo motor 222 by multiple stages, thereby increasing the output torque of the reducer 221 and providing sufficient driving force.

[0033] The transport assembly 23 of this embodiment includes a transport seat 231, a first limiting rod 232 and a second limiting rod 233 arranged on the transport seat 231, and a limiting block 234 arranged between the first limiting rod 232 and the second limiting rod 233. The two sides of the transport seat 231 are respectively connected to the first screw nut 213 and the second screw nut 214. The transport seat 231 and the first limiting rod 232 and the second limiting rod 233 enclose a limiting space 235 for limiting the rotation of the disk head 3, so that the limiting block 234 blocks and contacts the outer wall of the disk head 3. Specifically, the screw assembly 21 smoothly drives the transport seat 231 to move up and down through the first screw nut 213 and the second screw nut 214. The transport seat 231 and the first limiting rod 232 and the second limiting rod 233 enclose a limiting space 235 with a square structure, and the limiting block 234 blocks and contacts the outer wall of the disk head 3, thereby performing an enclosing limiting effect on the disk head 3, avoiding the position displacement of the disk head 3 during the up and down lifting process, and improving work safety.

[0034] The clamping device 4 of this embodiment includes a first clamping head 41, a second clamping head 42 spaced apart from the first clamping head 41, a driving motor 43 drivingly connected to the first clamping head 41, a pushing cylinder 44 arranged on the frame 1, and a pushing plate 45 drivingly connected to the pushing cylinder 44, the pushing plate 45 is connected to the second clamping head 42, the output end of the driving motor 43 is drivingly connected to a driving wheel 46, the first clamping head 41 is provided with a driven wheel 47, and a transmission belt 48 is connected between the driving wheel 46 and the driven wheel 47. Specifically, the pushing cylinder 44 is installed on one side of the frame 1, and the pushing cylinder 44 drives the pushing plate 45 to move horizontally, thereby driving the second chucking head 42 connected to the pushing plate 45 to move left and right and connect to one end of the disk head 3, so that the other end of the disk head 3 is connected to the first chucking head 41, and the driving motor 43 drives the active wheel 46 to rotate. The rotating active wheel 46 drives the driven wheel 47 to rotate through the transmission belt 48, and then drives the first chucking head 41 connected to the driven wheel 47 to rotate. The first chucking head 41 and the second chucking head 42 are used to clamp the two ends of the disk head 3 left and right, and then the disk head 3 is rotated smoothly, and the operation is stable and reliable.

[0035] The bottom of the frame 1 of this embodiment is provided with a tensioning wheel 5, which rolls against the first synchronous belt 218 and the second synchronous belt 2110. Specifically, as a preference, three tensioning wheels 5 are provided, and the three tensioning wheels 5 roll against the first synchronous belt 218 and the second synchronous belt 2110, respectively, so that the first synchronous belt 218 and the second synchronous belt 2110 are always kept in a tensioned state, thereby preventing the first synchronous belt 218 and the second synchronous belt 2110 from becoming loose and causing malfunction.
