Description

Technical Field

[0001] This utility model belongs to the technical field of automatic stop device for ring spinning machine yarn cake, and particularly relates to an automatic stop device for ring spinning machine yarn cake. Background Technology

[0002] This utility model is an improvement based on Chinese utility model patent CN210945900U, which discloses a yarn cake self-stopping mechanism, including a wedge, a push plate, and a push plate power device. It is used to realize the core yarn self-stopping function in the core yarn feeding device of a ring spinning machine. The wedge consists of two arc-shaped wedges respectively located at both ends of the push plate. The arc-shaped wedges are sleeved on the guide roller of the core yarn feeding device. The push plate power device is connected to the push plate and drives the push plate to make linear motion. The push plate power device is fixed below the guide roller. The advantage of this design is that when the yarn cake needs to stop automatically, the push plate power device drives the push plate to make linear motion, and the push plate drives the arc-shaped wedges to rotate around the guide roller. When the arc-shaped wedges rotate between the yarn cake and the guide roller, the yarn cake and the guide roller are separated, thereby causing the yarn cake to lose power and stop rotating, achieving the purpose of stopping the yarn cake's rotation.

[0003] However, when the wedge is inserted between the wire cake and the guide wheel, the wedge will rub against the surface of the wire cake, which may cause the wire to break. Summary of the Invention

[0004] The purpose of this utility model embodiment is to provide a self-stopping device for the yarn cake of a ring spinning machine, which aims to solve the technical problem that when the wedge is inserted between the yarn cake and the guide wheel, the wedge will rub against the surface of the yarn cake, which may cause the yarn to break.

[0005] The present invention is implemented as follows: An automatic stop device for the yarn cake of a ring spinning machine includes an electromagnetic actuator that is snapped into the frame of the spinning machine. A lifting base is fixed to the top of the electromagnetic actuator, and a first inclined groove is provided on the top surface of the lifting base. A support frame is provided above the lifting base, and a connecting seat is fixed to the bottom surface of the support frame. A second inclined groove is provided on the bottom surface of the connecting seat. The connecting seat and the lifting base are slidably connected by a guide. A wedge is provided between the first and second inclined grooves, and a transverse pull rod is fixed to the center of the wedge. The end of the pull rod is fixedly connected to the push plate of the electromagnetic actuator through a connecting rod.

[0006] Furthermore, two lifting bases are arranged side by side in the direction of the length of the lifting frame; two corresponding connecting seats are also provided; two corresponding wedges are also provided; the two wedges are connected together by a pull rod, the end of the pull rod is fixedly connected to the connecting rod, and the end of the connecting rod is fixedly connected to the push plate.

[0007] Furthermore, the connecting rod is arc-shaped.

[0008] Furthermore, the guide includes a sleeve fixed to the side of the connecting seat and a guide post fixed to the side of the lifting base. The guide post is inserted into the sleeve, and a tension spring is provided on the outside of the sleeve. One end of the tension spring is fixed at the connection between the sleeve and the connecting seat, and the other end of the tension spring is fixed at the connection between the guide post and the connecting seat.

[0009] Furthermore, the lifting frame includes two support plates, with through holes at both ends of the two support plates, a rotating shaft inside the through holes, and rollers sleeved on the rotating shaft.

[0010] Furthermore, a sensor mounting base is provided on the side or below the roller, and a photoelectric sensor is fixed inside the sensor mounting base.

[0011] The positive effects of this utility model are as follows: The magnetic driver pushes the push plate to make linear motion, which in turn drives the pull rod to make linear motion in the lateral direction, and drives the wedge block to move linearly between the first and second inclined grooves. Through the action of the inclined surface, the connecting seat is forced to rise. Since the connecting seat is fixed together with the lifting frame, the lifting frame is driven to rise. The rising lifting frame lifts the yarn cake, realizing the separation of the yarn cake from the front guide roller and the rear guide roller, thus achieving the purpose of self-stopping of the yarn cake. At the same time, it avoids scratching the yarn cake when the isolation gift is inserted between the yarn cake and the front guide roller or the yarn cake and the rear guide roller. It solves the technical problem in the prior art that when the wedge is inserted between the yarn cake and the guide roller, the wedge will rub against the surface of the yarn cake, which may cut the yarn.

Detailed Implementation

[0013] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments: In the description of this utility model, it should be understood that the terms "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0014] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0015] like Figures 1 to 3 The diagram shows the structure of a ring spinning machine's automatic stop device for the yarn cake, provided in an embodiment of this utility model. It includes an electromagnetic driver, which is snapped into the frame of the spinning machine. A lifting base is fixed to the top of the electromagnetic driver, and a first inclined groove is provided on the top surface of the lifting base. A support frame is provided above the lifting base, and a connecting seat is fixed to the bottom surface of the support frame. A second inclined groove is provided on the bottom surface of the connecting seat. The connecting seat and the lifting base are slidably connected via a guide. A wedge is provided between the first and second inclined grooves, and a transverse pull rod is fixed to the center of the wedge. The end of the pull rod is fixedly connected to the push plate of the electromagnetic driver via a connecting rod.

[0016] In this embodiment of the invention, the magnet driver has an iron core, and a conductive winding matching its power is wound around the outside of the iron core. The core has a linear actuator iron core. When the electromagnet is energized, the actuator iron core moves linearly. The end of the actuator core touches the locking mechanism of the spring, causing the spring to release its stored elastic potential energy, pushing the push plate 12 to move linearly, driving the pull rod to move linearly in the lateral direction, and driving the wedge block to move linearly between the first and second inclined grooves. The inclined surface forces the connecting seat to rise. Since the connecting seat is fixed together with the lifting frame, the lifting frame is driven to rise. The rising lifting frame lifts the silk cake, realizing the separation of the silk cake from the front guide roller and the rear guide roller 11, thus achieving the purpose of self-stopping of the silk cake. At the same time, it avoids scratching the silk cake when the isolation gift is inserted between the silk cake and the front guide roller or the silk cake and the rear guide roller. It solves the technical problem in the prior art that when the wedge is inserted between the silk cake and the guide roller, the wedge will rub against the surface of the silk cake, which may cut the silk thread. Conversely, manually pulling handle 9 pushes push plate 12, putting the spring in an energy storage state while the drive mechanism is locked, ensuring that the spring's elastic potential energy is not released. At the same time, the actuator core is pushed away from the trigger position and returns to the initial position to wait for the next action.

[0017] Specifically, a self-stop device for the yarn cake of a ring spinning machine includes an electromagnetic driver 7, which is snapped into the frame 3 of the spinning machine. A lifting base 4 is fixed to the top of the electromagnetic driver 7, and a first inclined groove is provided on the top surface of the lifting base 4. A support frame 2 is provided above the lifting base 4, and a connecting seat is fixed to the bottom surface of the support frame 2. A second inclined groove is provided on the bottom surface of the connecting seat. The connecting seat and the lifting base 4 are slidably connected by a guide 8. A wedge 6 is provided between the first and second inclined grooves. A transverse pull rod 5 is fixed to the center of the wedge 6, and the end of the pull rod 5 is fixedly connected to the push plate of the electromagnetic driver through a connecting rod 10.

[0018] Preferably, two lifting bases 4 are arranged side by side in the direction of the length of the lifting frame 2, which is the horizontal direction perpendicular to the axis of the silk cake 1; two corresponding connecting seats are also provided; two corresponding wedges 6 are also provided; the two wedges 6 are connected together by a pull rod 5, the end of the pull rod 5 is fixedly connected to the connecting rod 10, and the end of the connecting rod 10 is fixedly connected to the push plate 12.

[0019] The preferred connecting rod 10 is arc-shaped, which can adapt to the front guide roller or the rear guide roller 11, making use of space while avoiding the front guide roller or the rear guide roller 11.

[0020] The guide 8 includes a sleeve fixed to the side of the connecting seat and a guide post fixed to the side of the lifting base 4. The guide post is inserted into the sleeve, and a tension spring is provided on the outside of the sleeve. One end of the tension spring is fixed at the connection between the sleeve and the connecting seat, and the other end of the tension spring is fixed at the connection between the guide post and the connecting seat. The lifting frame 2 includes two saddle-shaped support plates 205. Each end of the two saddle-shaped support plates 205 has a through hole 201. A rotating shaft is installed inside the through hole 201, and a roller 202 is fitted over the rotating shaft. When the lifting frame 2 rises and contacts the silk cake, it contacts the silk cake through the roller 202. This rolling contact reduces friction between the lifting frame 2 and the silk cake, further preventing scratches on the silk cake when the insulating gift is inserted between the silk cake and the front guide roller or between the silk cake and the rear guide roller. This solves the technical problem in the prior art where, when a wedge is inserted between the silk cake and the guide roller, the wedge rubs against the surface of the silk cake, potentially cutting the silk thread.

[0021] A sensor mounting base 204 is provided on the side or below the roller 202. A photoelectric sensor 203 is fixed inside the sensor mounting base 204. When a thin thread is wrapped around the roller, the thread rotates with the roller and blocks the photoelectric sensor 203 in front of it, thus being detected by the photoelectric sensor and achieving the purpose of real-time monitoring.

[0022] The electromagnetic actuator is the pusher plate power device in Chinese utility model patent CN210945900U. To explain the structure of the electromagnetic actuator, the electromagnetic structure of the pusher plate power device in Chinese utility model patent CN210945900U is quoted below: To avoid misunderstandings caused by the serial numbers, the serial numbers have been removed from the reference; The electromagnetic actuator, also known as the push plate power device or drive mechanism, is driven by an electromagnet, a device that generates electromagnetic fields when energized. A conductive winding matching its power is wound around the outside of an iron core. The core contains a linear actuator. When the electromagnet is energized, the actuator moves linearly. The end of the actuator triggers the locking mechanism of a spring, causing the spring to release its stored elastic potential energy, pushing the push plate to move linearly. Conversely, manually pushing the push plate causes the arc-shaped wedge to rotate around the guide roller, forcing the wedge to move out of the space between the wire cake and the guide roller. At this time, the spring is in a stored energy state, while the drive mechanism is in a locked state, ensuring that the spring's elastic potential energy is not released. Simultaneously, the actuator is pushed away from the trigger position and returns to its initial position, waiting for the next action.

[0023] To explain the structure and operation of the electromagnetic driver, the content of Embodiment 1 in Chinese Utility Model Patent CN210945900U is quoted below: A push plate power device is located in the middle of the push plate. A power spring is located on the upper right side of the push plate power device. The left end of the power spring is connected to the push plate through a spring fixing seat. The left and right ends of the power spring are connected to the right side wall of the push plate power device. A limit stop is located in the middle of the push plate. The push plate power device has a handle. The middle part of the handle is connected to the housing of the push plate power device through a pin. The handle can rotate around the middle part. The upper part of the handle has a handle locking part. The middle part of the handle has a spring. The spring is restricted to the limit stop, which can make the handle automatically reset. The manual reset switch located at the lower part of the handle is exposed on the outside of the housing of the push plate power device. An electromagnet is located on the lower right side of the handle. The core of the electromagnet has a core iron. This device is fixed to the core wire bracket support rod by a fixing plate and a pressure plate.

[0024] In practical use: The yarn cake rotates under the drive of the front and rear guide rollers. At this time, the core yarn wound on the yarn cake begins to unfold and enters the front end of the drafting device under the guidance of the core yarn guide wheel. Then, the roving yarn unfolds and enters the rear end of the drafting device, which includes a cradle, front roller, middle roller, and rear roller. The roving yarn passes through the rear roller, middle roller, and front roller in sequence. Between the middle roller and the front roller, the core yarn and the roving yarn merge. After merging, the yarn passes through the drafting device and enters the yarn winding device through the yarn guide hook to complete the spinning process. During this process, the core yarn breakage detection system detects the core yarn breakage. When a yarn breakage occurs, the core-spun yarn breakage detection system sends an action signal to the pusher plate power unit. The electromagnet activates, attracting the core iron. The left end of the core iron pushes the manual reset switch located at the lower part of the handle to rotate around the middle of the handle. At this time, the interlocking handle engagement part and the limit stop separate. The pusher plate, no longer under the limiting force, slides to the left under the action of the power spring. When the pusher plate moves in a straight line, the sliding plate is in line contact with the long groove. Under the constraint of the long groove, the sliding plate can move along the straight line direction of the pusher plate and slide along the long groove, thereby driving the front arc-shaped wedge. The front and rear arc-shaped wedges rotate around the guide roller. When the front and rear arc-shaped wedges rotate between the yarn cake and the guide roller, the yarn cake and the guide roller are separated, thereby causing the yarn cake to lose power and stop rotating, achieving the purpose of stopping the yarn cake from rotating. When the above process is reversed, the yarn cake falls and starts rotating again. This reverse process is controlled by the handle 13. When the handle is pulled, the power spring is compressed and stores elastic potential energy. The handle engagement part and the limit stop block engage together. At this time, the front and rear arc-shaped wedges disengage from between the yarn cake and the guide roller, and the yarn cake falls and contacts the guide roller.

[0025] When a core yarn breaks, the core yarn breakage detection system cannot detect the core yarn breakage. At this time, the MRS is activated, the MRS device is started, the roving feeding is stopped, and the MRS device sends a core yarn breakage signal to the push plate power device. Then the above-mentioned operation process of the yarn cake self-stopping mechanism when a yarn breakage occurs will begin, which will not be repeated here.

Other beneficial results can be obtained by applying the disclosed information in different ways or by combining aspects of the disclosed embodiments.

Any changes, modifications, additions, reductions, or substitutions made by those skilled in the art within the scope of the present invention are also within the protection scope of the present invention.
