The position of the thread-clamping structure can be adjusted to apply different forces to the yarn.

[0004] However, the above-mentioned device has the following problems when in use: it is difficult to quickly stop the equipment and issue an early warning after the yarn breaks, which reduces the processing quality. Utility Model Content

[0005] The purpose of this invention is to provide a fully automatic cotton yarn twisting machine, which solves the problem that existing twisting equipment is difficult to stop and provide early warning after yarn breakage during processing, thus reducing processing quality.

[0006] To achieve the above objectives, this utility model provides a fully automatic cotton thread twisting machine, including a frame, on which a CNC cabinet and a control panel are mounted, the control panel being electrically connected to the CNC cabinet, and also including a detection mechanism;

[0007] The detection mechanism includes a mounting frame, a lower support block, an upper support block, a pressure sensor, a coil, a sealing plate, a rotating shaft, a gear plate, a drive device, and a guide device. The mounting frame is installed on the left side of the machine frame, the lower support block is installed on the mounting frame, the upper support block is installed on the top of the lower support block, the pressure sensor is installed on the inner wall of the upper support block and is electrically connected to the CNC cabinet, the coil is installed on the mounting frame, the sealing plate is installed on the right side of the coil, the rotating shaft is rotatably connected to the mounting frame, and the gear plate is integrally provided at its right end, the drive device is located on the side of the machine frame near the gear plate and is electrically connected to the CNC cabinet, and the guide device is located on the right side of the drive device.

[0019] Example 1:

[0020] like Figure 1 and Figure 2 As shown, where Figure 1 This is a schematic diagram of the overall structure of a fully automatic cotton thread twisting machine. Figure 2 This is a schematic diagram of the fabric coil structure. This utility model provides a fully automatic cotton yarn twisting machine: it includes a frame 101, a CNC cabinet 102, a control panel 103, and a detection mechanism. The detection mechanism includes a mounting frame 104, a lower support block 105, an upper support block 106, a pressure sensor 107, a fabric coil 108, a sealing plate 109, a rotating shaft 110, a gear disc 111, a drive device, and a guide device.

[0021] In this embodiment, a CNC cabinet 102 and a control panel 103 are mounted on the frame 101. The control panel 103 is electrically connected to the CNC cabinet 102.

[0022] The mounting bracket 104 is installed on the left side of the frame 101, the lower support block 105 is installed on the mounting bracket 104, the upper support block 106 is installed on the top of the lower support block 105, the pressure sensor 107 is installed on the inner wall of the upper support block 106 and is electrically connected to the CNC cabinet 102, the coil 108 is installed on the mounting bracket 104, the sealing plate 109 is installed on the right side of the coil 108, the rotating shaft 110 is rotatably connected to the mounting bracket 104, and the gear plate 111 is integrally provided at its right end, the driving device is located on the side of the frame 101 near the gear plate 111 and is electrically connected to the CNC cabinet 102, and the guiding device is located on the right side of the driving device. The mounting bracket 104 is fixed by positioning pins and bolts. The rotating shaft 110 is mounted on the mounting bracket 104 by a rotating bearing. The mounting bracket 104 and the gear disc 111 are provided with alignment through holes for cotton thread to pass through. The lower support block 105 is fixed by positioning pins and bolts arranged from left to right. The upper support block 106 is fixed by bolts arranged from bottom to top. The circular cavities of the lower support block 105 and the upper support block 106 slide with the cotton thread. The pressure sensor 107 is fixed by bolts and can be a sensor disclosed in existing technology CN220183534U. The coil 108 is fixed by bolts arranged from left to right. Its sidewall has through holes communicating with the internal cavity for easy cable routing of the pressure sensor 107. A rectangular opening is provided at the top for the cable to pass through. The sealing plate 109 is fixed by bolts. The driving device drives the gear disc 111 to rotate to achieve stranding, and the guiding device limits and guides the stranded cable. The mounting bracket 104 has a sleeve welded to the top for cable arrangement of the multiple pressure sensors 107.

[0023] Secondly, the bracket 112 is mounted on the frame 101; the power assembly is located on the side of the bracket 112 near the gear disc 111. The bracket 112 is fixed by locating pins and bolts, and the power assembly is used to realize the rotation of the gear disc 111.

[0024] Then, the drive motor 113 is mounted on the bracket 112, and the gear 114 is fixedly mounted on its output end and electrically connected to the CNC cabinet 102; the gear 114 meshes with the gear plate 111. The drive motor 113 is fixed by bolts, and the gear 114 is fixed to the motor shaft of the drive motor 113 by a flat key and a tension bolt.

[0025] Finally, the fixing frame 115 is installed on the right side of the frame 101; the guide tube 116 is installed on the fixing frame 115. The fixing frame 115 is fixed by positioning pins and bolts. The guide tube 116 is U-shaped, and the disc is fixed by bolts. The center of the disc is collinear with the center of the toothed disc 111. The inner and outer edges of both ends are rounded.

[0026] When using this invention to solve the problem of existing plying equipment where it is difficult to quickly stop and provide early warning after yarn breakage, thus reducing processing quality, the cotton thread output from the feed device is first passed sequentially through the through hole on the mounting bracket 104 from the left side of the equipment, then through the through hole of the gear disc 111, and the end is fixed to the winding device on the far right of the equipment. The drive motor 113 is controlled to drive the gear 114 to rotate, thereby rotating the gear disc 111 to complete the plying. The plyed cotton thread can be guided and limited by the guide tube 116. During the plying process, the yarn has a certain degree of tension. The pressure sensor 107 will detect a pressure value that meets the standard. When the yarn breaks, the yarn tension will disappear. At this time, the pressure value detected by the pressure sensor 107 will change, that is, the pressure value decreases. As a result, the control PLC inside the CNC cabinet 102 will trigger an external buzzer alarm based on the yarn breakage information. At the same time, the display screen on the control panel 103 can also display the alarm information. The equipment stops, and after the subsequent workers troubleshoot the problem, the equipment can continue processing. This solves the problem that existing twisting equipment is difficult to stop and warn quickly after the yarn breaks, which reduces the processing quality.

[0027] Example 2:

[0028] like Figure 3 As shown, where Figure 3 This is a schematic diagram of the overall structure of a fully automatic cotton thread twisting machine. Based on the first embodiment, this utility model provides a fully automatic cotton thread twisting machine, which also includes a combing device, including a screw slide 201 and a combing frame 202.

[0029] The lead screw slide 201 is located on the front side of the frame 101, and its servo motor is electrically connected to the CNC cabinet 102. The combing frame 202 is bolted to the slide base of the lead screw slide 201. The working process of the lead screw slide 201 is as follows: the ball screw is driven to rotate by a servo motor with an encoder and a brake mechanism. The T-nut of the ball screw is installed on the connecting part at the bottom of the slide base. The slide base is bolted to the linear slider of the linear guide slider module fixed on the frame 101, thereby realizing the movement of the slide base. The movement of the slide base can drive the combing frame 202 to move back and forth. The combing frame 202 is provided with mating holes that align with the mounting bracket 104 and the gear plate 111. The combing frame 202 does not contact or interfere with the sealing plate 109 and the gear plate 111 during reciprocating movement.

[0030] In this embodiment, by setting the comb frame 202 which can move back and forth, the yarns before plying are separated and guided to ensure that the yarns before plying do not stick together. This can reduce the phenomenon of yarn sticking caused by external forces such as static electricity, and further improve the plying quality.
