Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of clothing production cloth winding, in particular to a cloth winding mechanism for a clothing production line and a control system thereof. BACKGROUND

[0002] The core function of the cloth winding mechanism of the clothing production line is to realize high-precision and automatic winding forming of the cloth. Through dynamic tension control (±3% fluctuation suppression), self-adaptive winding alignment and intelligent roll changing process, it ensures the elimination of defects such as wrinkles and deviation in high-speed operation (200 m / min), guarantees the tight and flat winding, directly improves the material utilization rate and garment quality in the subsequent cutting link, and supports 24-hour continuous production to meet the stable winding needs of diversified fabrics such as cotton, chemical fiber and elastic cloth in flexible manufacturing.

[0003] The existing technology has the following disadvantages: The cloth winding mechanism commonly used in the current clothing manufacturing industry is usually equipped with a double-roller pressing system when completing the cloth winding process. This system uses the mechanical pressure of the upper and lower pressing rollers to expel the air between the multiple layers of cloth to achieve tight winding. However, there are significant technical limitations in actual operation: the inherent properties of different textile materials result in significant differences in thickness, for example, the average thickness of polyester-cotton blended composite cloth (about 0.8-1.2 mm) can be 2-3 times that of pure cotton cloth (about 0.3-0.5 mm). This difference in physical properties requires the pressing roller gap to have a dynamic adjustment function, but about 76% of the winding devices in existing production lines still use a static gap design fixed by bolts. This rigid structure cannot adapt to the production needs of multiple varieties, and when switching between different thicknesses of cloth, manual adjustment of mechanical parts is required, which not only reduces production efficiency (an average of 15-30 minutes is spent on each adjustment), but also may cause thin cloth to be pressed and thick cloth to be wound improperly due to improper pressure. This design flaw severely restricts the compatibility of the equipment for different types of cloth and has become one of the bottlenecks restricting modern flexible clothing production. SUMMARY

[0004] In view of the deficiencies of the prior art, the present application provides a cloth winding mechanism for a clothing production line and a control system thereof, which solves the problem of poor versatility caused by the inconvenience of adjusting the pressing roller gap.

[0006] The two sides of the pressing roller are respectively provided with an axle seat frame one and an axle seat frame two for supporting the rotation of the two groups of pressing rollers.

[0007] The side end of the axle seat frame two is provided with a limiting block, and the inner side of the angle steel frame is provided with a sliding groove, and the limiting block is inserted into the sliding groove.

[0008] In some embodiments, the side end of the angle steel frame is provided with a protruding block, a screw rod is arranged in the protruding block, the screw rod penetrates through the protruding block and movably connects the axle seat frame two, and a threaded connection relationship exists between the screw rod and the protruding block.

[0009] In some embodiments, a handle is arranged outside the screw rod to facilitate the rotation of the screw rod by an operator, the handle has a disc-shaped structure, and a plurality of gaps are arranged on the outer edge of the handle for fitting the fingers of the operator to increase the friction.

[0010] In some embodiments, a motor is arranged at the upper end of the angle steel frame to provide driving force, an output end of the motor is provided with a transmission shaft for conducting the motor power, and two driving bevel gears are arranged outside the transmission shaft. A driven bevel gear is arranged outside the shaft body at the side end of the pressing roller, and the driven bevel gear and the driving bevel gear are in tooth groove engagement.

[0011] In some embodiments, the axle seat frame two has an integral design, a vertical plate is arranged at the side end of the axle seat frame two, the vertical plate structure is penetrated by the transmission shaft, a bearing structure is arranged outside the transmission shaft, and a key shaft connection mode is adopted in the inner ring of the bearing.

[0012] In some embodiments, an inclined support is arranged at the side end of the bottom of the angle steel frame, a swing arm is rotatably arranged at the side end of the inclined support, and the inclined support is used for supporting the rotation of the swing arm. A tension sensor for monitoring tension is arranged outside the side end of the swing arm, an adjusting roller is rotatably arranged at the side end of the swing arm, and an adjusting rod is also rotatably arranged outside the swing arm.

[0013] In some embodiments, a connecting rod is arranged at the bottom of the adjusting rod, a plug is arranged at the side end of the connecting rod, and a plurality of groups of positioning holes are arranged at the bottom of the angle steel frame. The plug penetrates through the positioning hole and the connecting rod, so that the connecting rod can be fixed to the inner side of the angle steel frame, so that the positions of the adjusting rod and the swing arm are fixed, and the adjusting roller with the adjusted angle can also be fixed in position.

[0014] In some embodiments, a dust cover for providing protection for the driving structure is arranged at the top of the angle steel frame through bolt assembly, and a control panel for controlling the motor and the tension sensor is arranged at the side end of the dust cover.

[0015] In some embodiments, a control system used by a cloth winding mechanism of a clothing production line comprises: The winding control system is used for realizing accurate control of a cloth winding process.

An operator holds a handle and rotates it, so that the screw rod is driven to move the shaft seat frame two under the support of the limiting block and the sliding groove until the gap of the pressing roller is appropriate. In the above process, the driving bevel gear away from the motor side is always in contact with the driven bevel gear on the same side and moves outside the transmission shaft along with the movement of the pressing roller. The motor drives the driven bevel gear through the transmission shaft and the driving bevel gear, so that the pressing roller rotates oppositely and presses the cloth. When the tension sensor detects that the cloth is stretched too tightly or loosely, the operator can swing the position of the adjusting roller to adjust the tightness of the cloth, and after the adjustment is completed, the plug passes through the positioning hole and the connecting rod, so that the connecting rod is fixed inside the angle steel frame, the position of the adjusting rod and the swing arm is fixed, and the adjusting roller with the adjusted angle is also fixed in position. Through the above settings and processes, the structure has the following beneficial effects: 1. Compared with the existing cloth winding mechanism for the clothing production line, the screw adjustment mode provides additional stroke space for the pressing roller, so that the gap of the pressing roller can be accurately and quickly adjusted and applied to cloths of different thicknesses. 2. The adjusting roller is additionally provided and cooperates with the mechanical structure, so that the tightness of the cloth can be quickly adjusted by manual operation, and the cloth winding quality is improved.

The cloth is wound by the unwinding roller 2, and is threaded through the guide roller one 3 and the guide roller two 6, as well as the adjusting roller 21 and the pressure roller 7, and finally is wound by the external driving device connected by the winding roller 26. When winding different cloths, the gap of the pressure roller 7 is adjusted to adapt to cloths of different thicknesses. The operator holds the handle 15 and rotates it, so that the screw rod 14 is driven, and the shaft seat frame two 9 is translated under the support of the limiting block 17 and the sliding groove 16, until the pressure roller 7 has a proper distance. In the above process, the driving bevel gear 12 away from the motor 13 side is always in contact with the driven bevel gear 10 on the same side, and moves outside the transmission shaft 11 following the movement of the pressure roller 7.
