Description

Technical Field

[0001] This utility model relates to the technical field of yarn tailing machines, specifically a roving yarn tail residual angle cleaning and suction machine. Background Technology

[0002] In the textile industry, after the roving frame finishes spinning, there will be leftover yarn on the roving bobbin. In order to provide the roving frame with a reusable yarn bobbin, it is necessary to remove the leftover yarn from the roving bobbin.

[0003] According to the patent announcement number "CN204111063U" published on the China Patent Network, entitled "A Yarn End Retention Device for a Yarn End Removal Machine," it includes a suction-breaking device, a driving device, and a detection device. The suction-breaking device includes a negative pressure chamber, a suction pipe, an exhaust pipe, an air pipe, and a yarn guide plate. The negative pressure chamber is fixedly installed on the frame on the inlet side of the yarn end removal machine. The lower end of the suction pipe is connected to the negative pressure chamber, and the upper end faces the side of the bobbin with the yarn end. The two ends of the exhaust pipe are connected to the negative pressure chamber and the return box, respectively. The two ends of the air pipe are connected to the negative pressure chamber and the driving device, respectively. The yarn guide plate is fixed on the frame on the inlet side of the yarn end removal machine and is located between the bottom of the negative pressure chamber and the bobbin. The driving device includes a two-way solenoid valve, which is connected to the air pipe and the air source, respectively. The detection device consists of an optical fiber amplifier fixed below the yarn guide plate. This utility model ensures that the length of the yarn end retained on the bobbin is basically consistent, which facilitates the yarn end removal machine in finding broken yarn ends, improves the yarn end removal efficiency, and ensures the spinning quality.

[0004] While the aforementioned patent can improve the efficiency of yarn tail cleaning, the production time requirement leads to a short suction break time. In some cases, the yarn tail of the roving is tightly connected to the roving, and the short suction break time causes the yarn tail to overflow the suction break position before it is completely sucked off, affecting the cleaning effect of the roving yarn tail. Utility Model Content

[0005] The purpose of this utility model is to provide a roving tail corner cleaning and suction machine to solve the problem mentioned in the background art where the short suction-cutting time causes the tail yarn to overflow the suction-cutting position before it is completely cut, affecting the cleaning effect of the roving tail. To achieve the above objective, this utility model provides the following technical solution: A roving tail corner cleaning and suction machine includes a base, a negative pressure machine fixedly connected to the side wall of the base, an extension tube fixedly connected to the top of the negative pressure machine, two suction pipes fixedly connected to the top of the extension tube, a roving roller disposed at the top of the suction pipe, a photosensitive sensor located outside the roving roller disposed at the top of the inner wall of the suction pipe, a connecting rod fixedly connected to the top of the roving roller, a shearing mechanism disposed inside the suction pipe, and a rotating mechanism disposed at the bottom of the roving roller.

[0006] More preferably, the shearing mechanism includes a mounting base plate fixedly connected inside the suction tube, and a rebound rod extends through the interior of the mounting base plate. A rebound plate is fixedly connected to the top end of the rebound rod, and a rebound spring is installed between the mounting base plate and the rebound plate.

[0007] More preferably, two shearing plates are symmetrically installed on the top of the rebound plate, and the inside of the suction tube is provided with a shearing groove that matches the shearing plates.

[0008] More preferably, the suction tube has a negative pressure groove inside that communicates with the extension tube.

[0009] More preferably, the rotating mechanism includes a drive motor fixedly connected to the top of the rebound plate, and the output end of the drive motor is fixedly connected to a rotating disk, and the top of the rotating disk is fixedly connected to a connecting cone.

[0010] More preferably, the rotating mechanism includes a limiting block fixedly connected to one side of the rebound plate, and the inside of the suction tube is provided with a limiting groove that matches the limiting block.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: In this invention, the roving roller moves downward inside the suction pipe, causing the return plate to move downward. The downward movement of the return plate causes the shearing plate to move downward. The downward movement of the shearing plate opens the shearing groove. At this time, the negative pressure machine is started. The negative pressure machine can suck the yarn tail corner into the negative pressure groove through the shearing groove. After the yarn tail corner enters the negative pressure groove, the roving tail machine drives the roving roller to move upward. The movement of the roving roller drives the return plate to move upward through the return spring. The upward movement of the return plate drives the shearing plate to move downward. Through the shearing action of the shearing plate and the shearing groove, the yarn tail corner sucked into the negative pressure groove can be sheared. There is no need to suck the yarn tail corner with negative pressure, which improves the removal speed of the yarn tail corner, reduces the usage time for removing the yarn tail corner, and improves the working efficiency of the roving tail machine.

[0012] In this invention, when the negative pressure machine is sucking up the yarn tail surplus corner, the drive motor is started. The drive motor rotates and drives the rotating disk to rotate through the limiting block. The rotating disk drives the connecting cone to rotate, and the rotating connecting cone drives the roving roller to rotate at a 45-degree angle. This changes the position of the yarn tail surplus corner inside the suction pipe, ensuring that most of the yarn tail surplus corner can be sucked into the negative pressure groove. This increases the length of the yarn tail surplus corner being cut, greatly reduces the retained length of the yarn tail surplus corner, and improves the removal accuracy of the yarn tail surplus corner.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figures 1 to 5 This utility model provides a technical solution: a roving tail corner cleaning and suction machine, including a base 1, a negative pressure machine 2 fixedly connected to the side wall of the base 1, an extension tube 3 fixedly connected to the top of the negative pressure machine 2, two cleaning and suction pipes 6 fixedly connected to the top of the extension tube 3, a roving roller 4 set at the top of the cleaning and suction pipe 6, and a light sensor located outside the roving roller 4 set at the top of the inner wall of the cleaning and suction pipe 6. When the light sensor detects the passing of roving, it sends a command signal to the negative pressure machine 2 through the controller, and the negative pressure machine 2 starts automatically. A connecting rod 5 is fixedly connected to the top of the roving roller 4, a shearing mechanism is set inside the cleaning and suction pipe 6, and a rotating mechanism is set at the bottom of the roving roller 4.

[0017] In this embodiment: as the roving tail yarn machine is running, the connecting rod 5 can drive the roving roller 4 to move in a straight line. When the roving roller 4 moves to the top of the cleaning pipe 6, it moves downward and can penetrate into the cleaning pipe 6.

[0018] In this embodiment, as Figures 1 to 4As shown, the shearing mechanism includes a mounting base plate 9 fixedly connected inside the suction tube 6, and a rebound rod 10 passing through the inside of the mounting base plate 9. A rebound plate 11 is fixedly connected to the top of the rebound rod 10, and a rebound spring 12 is installed between the mounting base plate 9 and the rebound plate 11. Two shearing plates 14 are symmetrically installed on the top of the rebound plate 11, and a shearing groove 8 matching the shearing plate 14 is provided inside the suction tube 6. A negative pressure groove 7 communicating with the extension tube 3 is provided inside the suction tube 6.

[0019] In this embodiment: the roving roller 4 moves downward inside the suction pipe 6, causing the spring plate 11 to move downward. The downward movement of the spring plate 11 causes the shearing plate 14 to move downward. The downward movement of the shearing plate 14 can open the shearing groove 8. At this time, the negative pressure machine 2 is started. The negative pressure machine 2 can suck the yarn tail corner into the negative pressure groove 7 through the shearing groove 8. After the yarn tail corner enters the negative pressure groove 7, the roving tail machine drives the roving roller 4 to move upward. The movement of the roving roller 4 drives the spring plate 11 to move upward through the spring spring 12. The upward movement of the spring plate 11 drives the shearing plate 14 to move downward. Through the shearing action of the shearing plate 14 and the shearing groove 8, the yarn tail corner sucked into the negative pressure groove 7 can be sheared. There is no need to suck the yarn tail corner through negative pressure, which improves the removal speed of the yarn tail corner, reduces the usage time for removing the yarn tail corner, and improves the working efficiency of the roving tail machine.

[0020] In this embodiment, as Figures 3 to 5 As shown, the rotating mechanism includes a drive motor 13 fixedly connected to the top of the rebound plate 11, and a rotating disk 15 fixedly connected to the output end of the drive motor 13. A connecting cone 17 is fixedly connected to the top of the rotating disk 15. The rotating mechanism includes a limiting block 16 fixedly connected to one side of the rebound plate 11. The cleaning and suction pipe 6 has a limiting groove that matches the limiting block 16 inside.

[0021] In this embodiment: when the negative pressure machine 2 is sucking up the yarn tail corner, the drive motor 13 is started. The drive motor 13 rotates and drives the rotating disk 15 to rotate through the limiting block 16. The rotating disk 15 drives the connecting cone 17 to rotate. The rotating connecting cone 17 drives the roving roller 4 to rotate at a 45-degree angle, which can change the position of the yarn tail corner inside the suction pipe 6. This can ensure that most of the yarn tail corner can be sucked into the negative pressure groove 7, which can increase the length of the yarn tail corner shearing, greatly reduce the retention length of the yarn tail corner, and improve the removal accuracy of the yarn tail corner.

[0022] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
