Yarn knot automatic detection device of leasing machine

Abstract

The utility model discloses an automatic yarn knot detection device of a leasing machine. The automatic yarn knot detection device comprises a support and a guide roller installed on the support. The device further comprises a turning plate device and a proximity switch. The plate turnover device is installed on the support and located above the guide rollers. A yarn bundle channel is formed between the turning plate device and the guide roller; the proximity switch is installed on the support and located on one side of the plate turnover device. The turning plate device comprises a plate body, a connecting shaft and a connecting block which are integrated; the connecting block is arranged on one side of the bottom of the plate body and is close to the proximity switch. According to the automatic yarn knot detection device for the leasing machine, the plate turnover device is arranged above the guide roller, and the proximity switch is arranged on one side of the plate turnover device, so that when a yarn knot passes through the yarn bundle channel, the yarn knot pushes a plate body of the plate turnover device so as to drive the connecting block to move, and the proximity switch sends out a signal to stop the leasing machine; therefore, yarn knots are prevented from entering the leasing machine, and finally the phenomenon that yarn bundles are broken is avoided.

Description

Technical Field

[0001] The utility model relates to an automatic yarn knot detection device for a warping machine. Background Art

[0002] The warping machine is used to separate the yarn bundles dyed by the bundle dyeing machine and evenly lay them onto the warp beam for subsequent sizing. However, as the yarn bundles pass from the yarn drum to the warping machine, they are prone to tangling or knotting. If these knotted yarns (also known as yarn knots) are not promptly handled, they will break the yarn bundles after entering the warping machine, affecting both product quality and production schedule.

[0003] The existing solution is to install a photoelectric sensor on the yarn bundle channel. When a yarn knot passes through the yarn bundle channel, the photoelectric sensor will detect it and send a signal to stop the warping machine, thereby preventing the yarn knot from entering the warping machine [see Chinese patent documents CN110409032A and CN117344474A].

[0004] However, in actual production operations, this method often misses detection and has poor detection results. Utility Model Content

[0005] The purpose of the utility model is to solve the above problems and provide a warping machine yarn knot automatic detection device with better detection effect.

[0006] The technical solution for achieving the purpose of the utility model is: a warping machine yarn knot automatic detection device, including a bracket and a guide roller installed on the bracket; also including a flip device and a proximity switch; the flip device is installed on the bracket and is located above the guide roller; a yarn bundle channel is formed between the flip device and the guide roller; the proximity switch is installed on the bracket and is located on one side of the flip device.

[0007] The flap device includes an integral plate body, a connecting shaft and a connecting block; the connecting shaft is rotatably connected to the bracket via a bearing, and the connecting block is arranged on one side of the bottom of the plate body and close to the proximity switch.

[0008] The utility model has the positive effects: the yarn knot automatic detection device of the warping machine of the utility model is provided with a flap device above the guide roller, and a proximity switch is provided on one side of the flap device. When a yarn knot passes through the yarn bundle channel, the yarn knot will push the plate body of the flap device, thereby driving the connecting block to move, so that the proximity switch will send a signal to stop the warping machine, thereby blocking the yarn knot from entering the warping machine, and finally avoiding the phenomenon of yarn bundle breakage. BRIEF DESCRIPTION OF THE DRAWINGS

[0009] Figure 1 It is a structural schematic diagram of the automatic yarn knot detection device of the warping machine of the present invention.

[0010] Figure 2 for Figure 1 AA view in . DETAILED DESCRIPTION

[0011] (Example 1)

[0012] See also Figure 1 and Figure 2 The automatic yarn knot detection device of the warping machine of this embodiment includes a bracket 1, a guide roller 2, a turning device 3 and a proximity switch 4.

[0013] The guide roller 2, the flap device 3 and the proximity switch 4 are all installed on the bracket 1. The flap device 3 is installed above the guide roller 2, and the proximity switch 4 is installed on one side of the flap device 3. A yarn bundle channel 5 is formed between the flap device 3 and the guide roller 2.

[0014] The flap device 3 includes a plate body 31, a connecting shaft 32 and a connecting block 33. The connecting shaft 32 is rotatably connected to the bracket 1 through a bearing, and the connecting block 33 is arranged on one side of the bottom of the plate body 31 and close to the proximity switch 4.

[0015] When the yarn bundle 6 passes through the yarn bundle channel 5, if there is a yarn knot, it will push the plate body 31 of the flap device 3, thereby driving the connecting block 33 to move, so that the proximity switch 4 will send a signal to stop the warp splitting machine, thereby blocking the yarn knot from entering the warp splitting machine, and ultimately avoiding the phenomenon of yarn bundle breakage.
