Technical Field

[0001] The utility model relates to the technical field of spinning machines, in particular to a wire break alarm device for a spinning machine. Background Art

[0002] The spinning machine is the most common machine in a textile mill. It is mainly responsible for processing raw materials such as cotton into yarn. The spinning machine processes the raw materials into yarn suitable for textile through pre-treatment, cleaning, opening, drawing and other stages. When the spinning machine is in use, in order to avoid the breakage of one of the multiple groups of yarns and the inability to discover it in time, a broken thread alarm device is often installed on the spinning machine.

[0003] However, the existing spinning machine's broken yarn alarm device has a single structure and cannot issue a conspicuous alarm in time when a certain yarn breaks, resulting in the broken yarn being unable to be discovered and handled by the user in time, so that the broken yarn will be directly entangled with other yarns, which will directly affect the normal operation of the device and pose a great hidden danger. Utility Model Content

[0004] The utility model aims to solve the defect in the prior art that a striking warning cannot be issued in time when a certain yarn is broken, and proposes a thread breaking alarm device for a spinning machine.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A thread break alarm device for a spinning machine comprises a frame, wherein mounting posts are rotatably mounted at the bottom of both sides of the front side of the frame, and each group of the mounting posts is provided with a plurality of first arcuate grooves in sequence along the front-to-back direction, wherein yarns are transmission-connected in the first arcuate grooves, and an extension frame is fixed to the top of the front side of the frame, and an auxiliary alarm component used in conjunction with the yarn is provided on the extension frame.

[0007] The auxiliary alarm component includes multiple groups of top plates fixed on the extension frame in sequence along the front-to-back direction, and there is a certain distance between the sides of the two adjacent groups of top plates that are close to each other. Each group of top plates is inserted into the lifting frame, and an arc-shaped seat is fixed on the top of the lifting frame and the bottom of the arc-shaped seat is attached to the top plate. A second arc-shaped groove for use with yarn is provided on the arc-shaped seat, and a spring is fixed at the bottom of the inner cavity of each group of the lifting frames and the top of the spring is fixed on the top plate. A turning frame is rotatably installed on the right side of the front side of the top plate, and an alarm is provided on the left end of the turning frame. A horizontal groove is provided on the turning frame, and a vertical plate is fixed on the front side of the arc-shaped seat, and a column inserted in the horizontal groove is fixed on the bottom of the front side of the vertical plate.

[0008] An anti-dropping convex plate is fixed to one end of the plug post away from the vertical plate, and the back side of the anti-dropping convex plate is attached to the flip frame.

[0009] A position sensor used in conjunction with the top plate is embedded on one side of each group of lifting frames.

[0010] There is a certain distance between the turning frame and the extending frame, and there is a certain distance between the alarm and the yarn.

[0011] Each group of lifting frames is in a T-shaped structure as a whole.

[0012] Reinforcement inclined plates are fixed to the backs of both sides of the bottom of the extension frame, and one end of the reinforcement inclined plate away from the extension frame is fixed to the frame.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] The thread break alarm device of the spinning machine can continuously give an upward pushing force to the arc seat and the lifting frame by setting an auxiliary alarm component and the spring design, and under the downward pressure continuously given by the yarn, the arc seat can be fitted with the top plate and the spring can be kept in a stretched state. If a group of yarns is broken, the elastic rebound of the spring can be used to push the arc seat and the vertical plate to move upward synchronously, and with the cooperation of the plug column and the horizontal groove, the turning frame and the alarm can be driven to swing upward quickly, so that this group of alarms can be much higher than other alarms, so as to expand the warning range of the alarm, make the position of the alarm more eye-catching, and make the alarm at the broken yarn easier to be found by the staff, so as to deal with the broken yarn in time.

DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] Example

[0022] Reference Figure 1-Figure 4, a thread-break alarm device for a spinning machine comprises a frame 1, mounting columns 2 are rotatably mounted at the bottom of both sides of the front of the frame 1, a plurality of first arc-shaped grooves 3 are sequentially arranged on each group of mounting columns 2 along the front-back direction, a yarn 4 is connected in a transmission manner in the first arc-shaped grooves 3, an extension frame 5 is fixed to the top of the front of the frame 1, a reinforcing inclined plate 17 is fixed to the back of both sides of the bottom of the extension frame 5, the end of the reinforcing inclined plate 17 away from the extension frame 5 is fixed to the frame 1, the design of the reinforcing inclined plate 17 can reinforce and support the extension frame 5, and improve the overall strength of the extension frame 5, an auxiliary alarm component used in conjunction with the yarn 4 is arranged on the extension frame 5, and the auxiliary alarm component comprises a plurality of first arc-shaped grooves 3 and a plurality of first arc-shaped grooves 3. A plurality of groups of top plates 6 are sequentially fixed on the extension frame 5 in the rear direction, and there is a certain distance between the two adjacent groups of top plates 6 on the side close to each other. A lifting frame 7 is inserted on each group of top plates 6, and each group of lifting frames 7 is an overall T-shaped structure. The lifting frame 7 with an overall T-shaped structure can prevent the lifting frame 7 from being separated from the top plate 6, thereby improving the stability of the lifting frame 7 when moving. An arc seat 8 is fixed to the top of the lifting frame 7, and the bottom of the arc seat 8 is attached to the top plate 6. A second arc groove 9 for use with the yarn 4 is provided on the arc seat 8. A spring 10 is fixed to the bottom of the inner cavity of each group of lifting frames 7, and the top of the spring 10 is fixed to the top plate 6. The right side of the front side of the top plate 6 is rotatably mounted The turning frame 11 is provided with an alarm 12 at the left end of the turning frame 11. A position sensor 18 used in conjunction with the top plate 6 is embedded on one side of each lifting frame 7. The design of the position sensor 18 can detect the position change in time when the lifting frame 7 is reset upward, so as to open the alarm 12 in time. A transverse groove 13 is provided on the turning frame 11. A vertical plate 14 is fixed on the front of the arc seat 8. A plug 15 inserted in the transverse groove 13 is fixed on the bottom of the front of the vertical plate 14. By setting an auxiliary alarm component, when the yarn 4 is broken, the warning range of the alarm 12 can be expanded in time, so that the position of the alarm 12 is more eye-catching, which is convenient for the alarm at the broken yarn 4. 12 is easier to be discovered by the staff so that the broken yarn 4 can be dealt with in time. An anti-slip convex plate 16 is fixed to the end of the plug post 15 away from the vertical plate 14, and the back of the anti-slip convex plate 16 is attached to the turning frame 11. By setting the anti-slip convex plate 16, the plug post 15 and the turning frame 11 can be synchronously limited to prevent the plug post 15 from being separated from the turning frame 11. A controller is provided on the right side of the front of the frame 1. There is a certain distance between the turning frame 11 and the extension frame 5, and there is a certain distance between the alarm 12 and the yarn 4. The design of the distance can prevent the turning frame 11 from colliding with the extension frame 5 when turning, and can prevent the alarm 12 from colliding with the yarn 4 when swinging.

[0023] In the present invention, when the multiple groups of yarns 4 are not broken normally, a downward pressure is applied to the arc seat 8, so that the arc seat 8 is directly attached to the top plate 6, and the lifting frame 7 will move down synchronously with the arc seat 8 and stretch the spring 10. If one of the multiple groups of yarns 4 is broken, the downward pressure on the arc seat 8 in contact with the group of yarns 4 will disappear directly. At this time, the elastic rebound of the spring 10 can be used to drive the arc seat 8, the lifting frame 7 and the vertical plate 14 to move up synchronously, thereby driving the plug post 15 to move up synchronously, and with the cooperation of the transverse groove 13, the arc seat 8, the lifting frame 7 and the vertical plate 14 can be driven to move up synchronously. The dynamic turning frame 11 and the alarm 12 swing upward synchronously, and the position sensor 18 monitors the distance between the bottom of the lifting frame 7 and the top plate 6 in real time. If the change in the distance exceeds the preset value, the alarm 12 is turned on in time. At this time, the alarm 12 of this group of upwardly swinging alarms can be much higher than other alarms 12, which expands the warning range of the alarm 12, making the position of the alarm 12 at the broken yarn 4 of this group more eye-catching, making the alarm 12 at the broken yarn 4 easier to be found by the staff, so that the staff can deal with the broken yarn 4 in time.
