Description

Technical Field

[0001] The utility model relates to the technical field of strip coiling machines, in particular to a strip surging automatic stopping device for strip coiling machines. Background Art

[0002] The sliver lap machine is a preparatory machine for cotton combing. It arranges the combed or pre-drawn slivers in parallel to form laps. It primarily consists of a sliver feeding, drafting, compacting, and lap-forming mechanism. Typically, 14-20 slivers are drawn from two cans and arranged parallel to the sliver guide plate by sliver guide rollers. They then enter the drafting unit for a brief drafting period. Compacting rollers compact the sliver layer, and the lap rollers wind them onto bobbins to form laps for the comber. During the combing preparation process, the comber is provided with laps that are straight and parallel, accurately weighed, precisely wound, with neat edges and uniform lengthwise and widthwise directions. The quality of the laps directly impacts the comber's output, quality, noil, and efficiency. However, sliver slugging can occur on the lap table due to problems such as splice breakage or poor surface cleanliness during lap production.

[0003] A Chinese patent application, authorized with publication number CN202369700U, discloses a sliver breakage automatic stop mechanism for a sliver lap machine. The sliver lap machine includes a sliver guide frame, a sliver drafting device, and a rolling device. Photoelectric sensors are located on both sides of the sliver guide frame. Slivers pass through the sliver guide frame and enter the sliver drafting device, which is connected to the rolling device. However, conventional sliver lap machine drafting automatic stop mechanisms also have drawbacks. The main drawback is that the single photoelectric sensor makes the automatic stop mechanism prone to malfunction, leading to equipment failure, posing a serious threat to the safety of equipment and personnel, and reducing production efficiency. Utility Model Content

[0004] In order to overcome the defects of the prior art automatic stop device that is prone to malfunction and reduces production efficiency, the utility model provides a strip-flow automatic stop device for a strip coiling machine.

[0005] The technical solution adopted by the utility model to solve its technical problems is: a strip-rushing automatic stopping device for a strip-winding machine, comprising a photoelectric sensor and a roller arranged on a strip guide frame, a semi-open bearing seat symmetrically provided on the strip guide frame, the roller being placed and installed on the symmetrically provided semi-open bearing seat, a rotating bearing being provided at both ends of the roller, a U-shaped frame being provided on the lower side of the strip guide frame, the U-shaped frame being fixed on the rotating bearing, the bottom of the U-shaped frame being connected to a switch touch plate through a spring, the switch touch plate being hinged on the bracket, the bracket being fixed on the base, and a touch switch being provided on the base.

[0006] As a further improvement of the present invention, the photoelectric sensors are symmetrically arranged on the guide bar frame.

[0007] As a further improvement of the present invention, the photoelectric sensor is a diffuse reflection type photoelectric sensor.

[0008] As a further improvement of the present invention, the base is fixed to the ground by bolts.

[0009] As a further improvement of the present invention, the bracket is arranged at the center of the base, the touch switch is arranged at the left end of the base, the middle part of the switch touch plate is hinged to the top of the bracket, and the spring is arranged at the right end of the switch touch plate.

[0010] As a further improvement of the present invention, the roller and the U-shaped frame are both made of lightweight carbon fiber.

[0011] Compared with the existing technology, the utility model has the beneficial effects: in this solution, when there is a surge on the table, the cotton strips are diffusely reflected to the photoelectric sensor, and the photoelectric sensor sends a signal to disconnect the circuit, thereby realizing automatic parking. The roller rotates normally on the wire. When there is a surge on the table, the surge disturbance lifts the roller, and the other end of the roller control switch touches the touch switch, sending a signal to disconnect the circuit, thereby realizing automatic parking. The two-level parallel parking setting of the photoelectric sensor and the roller can reduce the risk of failure of the automatic parking device, which can effectively avoid cotton strip waste, reduce equipment damage, reduce safety hazards, and improve production efficiency.

[0016] In order to make the technical solution and beneficial effects of the present invention more clearly understood, the present invention will be further described in detail below with reference to specific embodiments.

[0017] Reference Figure 1 and Figure 2The embodiment of the utility model discloses a strip-rushing automatic stopping device for a strip-winding machine, comprising a photoelectric sensor 2 and a roller 3 arranged on a strip guide frame 1, a semi-open bearing seat 4 symmetrically provided on the strip guide frame 1, the roller 3 is placed and installed on the symmetrically provided semi-open bearing seat 4, a rotating bearing 5 is provided at both ends of the roller 3, a U-shaped frame 6 is provided on the lower side of the strip guide frame 1, the U-shaped frame 6 is fixed on the rotating bearing 5, the bottom of the U-shaped frame 6 is connected to the switch touch plate 8 through a spring 7, the switch touch plate 8 is hinged on the bracket 9, the bracket 9 is fixed on the base 10, and the base 10 is provided with a touch switch 11.

[0018] The photoelectric sensor 2 is a diffuse reflection type photoelectric sensor and is symmetrically arranged on the guide frame 1. Under normal circumstances, the photoelectric sensor 2 is in a normally closed state when in operation, and the equipment operates normally. When there is a surge on the table, the cotton strips are diffusely reflected to the photoelectric sensor 2. The photoelectric sensor 2 senses and transmits the signal to the electrical system PLC through the data transmission line. The system sends a command signal to disconnect the circuit, thereby achieving automatic parking. The roller 3 and the U-shaped frame 6 are both made of lightweight carbon fiber material, which is light in weight and moves more obviously when subjected to force. Under normal circumstances, the roller 3 rotates normally on the wire. When there is a surge on the table, the surge disturbance lifts the roller 3, and the roller 3 then drives the U-shaped frame 6 to rise. The spring 7 pulls up one end of the switch touch plate 8, and the other end of the switch touch plate 8 contacts the touch switch 11. The touch switch 11 transmits the signal to the electrical system PLC through the data transmission line. The system sends a command signal to disconnect the circuit, thereby achieving automatic parking. The two-stage parallel parking setting of the photoelectric sensor 2 and the roller 3 can reduce the risk of failure of the automatic stop device, effectively avoid sliver waste, reduce equipment damage, reduce safety hazards, and improve production efficiency.

[0019] The base 10 is fixed to the ground by bolts, the bracket 9 is set at the center of the base 10, the touch switch 11 is set at the left end of the base 10, the middle part of the switch touch plate 8 is hinged to the top of the bracket 9, and the spring 7 is set at the right end of the switch touch plate 8.

[0020] It should be understood that the specific embodiments described herein are only used to understand the present invention and are not used to limit the present invention. All other embodiments obtained by those skilled in the art without making any creative work are within the scope of protection of the present invention.
