Description

Technical Field

[0001] This utility model relates to the field of flat wire drawing machines, and in particular to a flat wire drawing machine that can reduce the generation of waste wire. Background Technology

[0002] A flat filament drawing machine is a piece of equipment used to process plastic materials. It is mainly used to process plastic raw materials into flat filaments. Its working principle is to make the plastic raw materials into the required flat filament products through processes such as heating, extrusion, stretching and cooling. When the flat filament drawing machine is working, multiple sets of drive rollers are used to drive the finished filaments to assist in their stable subsequent winding. However, traditional flat filament drawing machines cannot monitor the tightness of the finished filaments in real time. As a result, when the finished filaments are too loose or too tight, they cannot be alerted and the machine cannot be stopped in time. This can lead to the finished filaments being prone to breakage due to excessive tension and tangling due to excessive looseness. This directly increases the amount of waste filaments generated and greatly reduces the overall processing efficiency and processing effect of the equipment.

[0003] To address the aforementioned problems, this utility model provides improvements. Summary of the Invention

[0004] This invention proposes a flat wire drawing machine that can reduce waste wire generation, thus solving the aforementioned problems existing in the use of the prior art.

[0005] The technical solution of this utility model is implemented as follows: a flat wire drawing machine that can reduce waste wire generation includes a flat wire drawing machine body. A mounting frame is provided on one side of the flat wire drawing machine body. Multiple sets of transmission rollers for auxiliary transmission of finished wire are rotatably mounted on the top and bottom of the back of the inner cavity of the mounting frame in the left and right direction. Multiple sets of auxiliary motors with output shafts fixed to the transmission rollers are fixed on the back of the mounting frame through a back frame. The multiple sets of transmission rollers are staggered in the upper and lower parts. An anti-wire breakage component is provided on the mounting frame for use with the finished wire.

[0006] The present invention, as described above, provides a flat wire drawing machine that reduces waste wire generation. Further, the anti-breakage assembly includes two sets of fixed frames sequentially fixed along the left-right direction to the adjacent sides of two sets of upper and lower transmission rollers via support plates. A strip-shaped frame for the finished wire to pass through is fixed to the adjacent side of each fixed frame. A push plate is slidably disposed within the strip-shaped frame, with the adjacent side of the push plate abutting against the finished wire. Each set of strip-shaped frames has strip-shaped holes on both the front and back sides, and a T-shaped plate, with its inner side fixed to the push plate, is slidably disposed within each set of strip-shaped holes. Side plates are fixed to the inner sides of the front and back of the strip frame, and a first spring is fixed to the side of the side plate and the T-shaped plate that are close to each other. Multiple sets of second springs are fixed in sequence along the front and back direction on the left side of the inner cavity of the strip frame and the side of the push plate that are close to each other. An infrared transmitter and an infrared receiver are respectively provided on the front and back of the inner cavity of each set of the fixing frame. A barrier plate that penetrates the strip frame and is adapted to the infrared transmitter and infrared receiver is symmetrically fixed on the side of the push plate that is far from each other. Alarms are provided on both sides of the top of the mounting frame.

[0007] The present invention provides a flat wire drawing machine that can reduce waste wire generation as described above. Further, there is a gap between the push plate on the left and the left side of the inner cavity of the left strip frame, and the right side of the push plate on the right is attached to the right side of the inner cavity of the right strip frame.

[0010] The present invention provides a flat wire drawing machine that can reduce waste wire generation as described above. Further, each of the opposite sides of the fixed frame is fixed with an L-shaped lifting rod, one end of which is fixed to the top of the mounting frame.

[0011] The present invention provides a flat wire drawing machine that can reduce waste wire generation as described above, further comprising: the push plate having an arc-shaped structure on the side near the finished wire.

[0012] In summary, the beneficial effects of this utility model are as follows:

[0013] 1. By setting up an anti-broken wire component, this utility model can monitor the tightness of the finished wire between the transmission rollers in real time.

This can effectively prevent the finished wire from easily getting tangled or breaking during transmission due to being too loose or too tight, thereby effectively reducing the amount of waste wire generated and improving the overall processing efficiency and processing effect of the device.

[0014] 2. By setting different spacings, this utility model can control the positional relationship between the barrier plate and the infrared transmitter and receiver, so as to distinguish between looseness and tightness, improve the monitoring accuracy of the tightness of the finished yarn, and avoid false alarms.

[0015] 3. By setting the distance between the strip frame and the transmission roller, this utility model can effectively prevent the strip frame from contacting and rubbing against the transmission roller when it moves, thus avoiding interference with the normal rotation of the transmission roller. It can also form the finished wire into a certain arc shape, which facilitates real-time monitoring of the tightness.

[0016] 4. By limiting the number of second springs, this utility model provides sufficient support for the finished wire, ensuring that the left push plate remains stable during transmission and that the movement range is within a controllable range. This avoids the left push plate moving too much due to insufficient spring force, which would affect the monitoring accuracy.

[0017] 5. By setting an L-shaped lifting rod, this utility model can lift and reinforce the fixing frame, which improves the overall stability of the fixing frame and prevents it from falling and breaking due to its long extension length, thereby further improving the stability of monitoring the tightness of the finished yarn.

[0018] 6. By limiting the shape of one side of the push plate, this utility model can effectively prevent wear on the finished wire, so that the finished wire can be transmitted normally and avoid obstruction. Attached Figure Description

[0025] The following will refer to the appendix in the embodiments of this utility model. Figure 1-4 The technical solutions in the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model. Example

[0026] A flat yarn drawing machine that reduces waste yarn generation includes a flat yarn drawing machine body 1. A mounting frame 2 is provided on one side of the machine body 1. A controller is mounted on the right side of the top of the mounting frame 2 via a vertical plate. Multiple sets of transmission rollers 3, which provide auxiliary transmission for the finished yarn, are sequentially mounted on the top and bottom of the back of the inner cavity of the mounting frame 2 in a left-right direction. Multiple sets of auxiliary motors 4, whose output shafts are fixed to the transmission rollers 3, are fixed to the back of the mounting frame 2 via a back frame. The multiple sets of transmission rollers 3 are staggered. An anti-breakage assembly for use with the finished yarn is provided on the mounting frame 2. The anti-breakage assembly includes two sets of fixing frames 5, which are sequentially fixed in a left-right direction to the adjacent sides of the upper and lower sets of transmission rollers 3 via support plates. A strip frame 6 for the finished yarn to pass through is fixed to the adjacent side of the fixing frames 5. The strip frame 6 slides within the strip frame 6. A push plate 7 is provided, with the sides of the push plates 7 close to each other attached to the finished wire. Each set of strip frames 6 has strip holes 9 on both the front and back. A T-shaped plate 8, which is fixed to the push plate 7 on the inner side, is slidably installed in each set of strip holes 9. Side plates are fixed to the inner sides of the front and back of the strip frames 6, and a first spring 10 is fixed to the side of the side plate and the T-shaped plate 8 close to each other. Multiple sets of second springs 14 are fixed in sequence along the front and back direction on the left side of the inner cavity of the left strip frame 6 and the side of the push plate 7 close to each other. An infrared transmitter 11 and an infrared receiver 12 are respectively provided on the front and back of the inner cavity of each set of fixing brackets 5. A barrier plate 13, which penetrates the strip frame 6 and is adapted to the infrared transmitter 11 and the infrared receiver 12, is symmetrically fixed on the side of the push plates 7 that is far from each other. An alarm 16 is provided on both sides of the top of the mounting frame 2.

[0027] Specifically, this utility model, by setting up an anti-broken wire component, utilizes real-time monitoring of the on / off status of the infrared transmitters 11 and infrared receivers 12 arranged on the left and right to quickly determine the tightness of the finished wire. This allows for timely warnings and control of the flat wire drawing machine body 1 and auxiliary motor 4 to stop when the finished wire is too loose or too tight. This effectively prevents the finished wire from easily tangling or breaking during transmission due to being too loose or too tight, thereby effectively reducing the amount of waste wire generated and improving the overall processing efficiency and effect of the device.

[0028] There is a gap between the left push plate 7 and the left side of the inner cavity of the left strip frame 6, and the right side of the right push plate 7 is attached to the right side of the inner cavity of the right strip frame 6.

[0029] Specifically, the different spacing designs can control the positional relationship between the barrier plate 13 and the infrared transmitter 11 and infrared receiver 12, so as to distinguish between looseness or tightness, improve the monitoring accuracy of the tightness of the finished yarn, and avoid false alarms.

[0030] There are gaps between the top and bottom of the strip frame 6 and the drive roller 3.

[0031] Specifically, by utilizing the gap between the strip frame 6 and the drive roller 3, it is possible to prevent the strip frame 6 from contacting and rubbing against the drive roller 3 during movement, thus avoiding interference with the normal rotation of the drive roller 3. At the same time, it can form a certain arc shape for the finished yarn, which facilitates real-time monitoring of the tightness of the finished yarn.

[0032] The number of second springs 14 on the left push plate 7 is at least five.

[0033] Specifically, limiting the number of second springs 14 can provide sufficient support for the finished wire, so that the movement of the left push plate 7 during transmission is within a controllable range, avoiding the left push plate 7 from moving too much due to insufficient spring force, which would affect the monitoring accuracy.

[0034] L-shaped lifting rods 15 are fixed to the front sides of the fixed frame 5 that are far apart from each other, and one end of the L-shaped lifting rod 15 is fixed to the top of the mounting frame 2.

[0035] Specifically, the design of the L-shaped lifting rod 15 can lift and reinforce the fixing frame 5, preventing one end of the fixing frame 5 from easily falling and breaking due to its long extension length, and further improving the stability of monitoring the tightness of the finished yarn.

[0036] The pusher plate 7 has an arc-shaped structure on the side closest to the finished wire.

[0037] Specifically, limiting the shape of one side of the push plate 7 can effectively prevent wear on the finished wire, so that the finished wire can be transmitted normally and avoid obstruction.

[0038] The specific usage process is as follows: In the initial state, under the elastic force of the first spring 10 and the second spring 14, the left push plate 7 continuously provides a stable pushing force to the finished wire within the strip frame 6, causing the left blocking plate 13 to disengage from the infrared emitter 11 and the infrared receiver 12, thus placing the left infrared emitter 11 and the infrared receiver 12 in a pass-through state. At this time, the finished wire is in a suitable tension state. If the finished wire is too taut, a counter-pushing force to the left will be applied to the left push plate 7, thereby driving the blocking plate 13 to move synchronously to the left and blocking the infrared emitter 11 and the infrared receiver 12, placing them in an open circuit state. At this time, the open circuit signal is quickly sent to the controller, and the controller then controls... The alarm 16 is activated quickly, simultaneously shutting down the flat wire drawing machine body 1 and auxiliary motor 4 to prevent the finished wire from breaking due to excessive tension, facilitating quick maintenance by staff. In the initial state, the right push plate 7, under the pressure of the finished wire, will directly adhere to the right side of the inner cavity of the right strip frame 6, and the right barrier plate 13 is positioned between the right infrared transmitter 11 and the infrared receiver 12. At this time, the right infrared transmitter 11 and the infrared receiver 12 are in an open circuit state. If the finished wire is too loose, the pressure on the right push plate 7 will decrease or disappear completely. Then, the elastic rebound of the right first spring 10 can drive the right push plate 7 and the barrier plate 13 to move to the left and disengage from the infrared transmitter 11 and the infrared receiver 12. 2. Quickly put the infrared transmitter 11 and infrared receiver 12 on the right side into a closed-circuit state. At this time, the closed-circuit signal is quickly sent to the controller, which then controls the alarm 16 to be activated quickly and simultaneously shuts down the flat wire drawing machine body 1 and auxiliary motor 4. This prevents the finished wire from being too loose and tangling together. Separate monitoring of the tightness can further improve the monitoring accuracy, thereby effectively reducing the amount of waste wire generated. This utility model, by setting up an anti-broken wire component, can quickly know the tightness of the finished wire by real-time monitoring of the on / off state of the infrared transmitter 11 and infrared receiver 12 set on the left and right sides. In this way, when the finished wire is too loose or too tight, an alarm can be issued in time and the flat wire drawing machine body 1 and auxiliary motor 4 can be controlled to stop in time. This effectively prevents the finished yarn from easily tangling or breaking due to being too loose or too tight during transmission, thereby effectively reducing the amount of waste yarn and improving the overall processing efficiency and effect of the device. The different spacing designs can control the positional relationship between the barrier plate 13 and the infrared transmitter 11 and infrared receiver 12, so as to distinguish between the looseness or tightness of the monitored yarn, improve the monitoring accuracy of the tightness of the finished yarn, and avoid false alarms. The spacing between the strip frame 6 and the transmission roller 3 can prevent the strip frame 6 from contacting and rubbing against the transmission roller 3 when it moves, thus avoiding interference with the normal rotation of the transmission roller 3. At the same time, it can form a certain arc for the finished yarn, which is convenient for real-time monitoring of the tightness of the finished yarn.Limiting the number of second springs 14 provides sufficient support for the finished wire, ensuring that the movement of the left push plate 7 during transmission remains within a controllable range. This prevents excessive movement of the left push plate 7 due to insufficient spring force, which could affect monitoring accuracy. The L-shaped lifting rod 15 reinforces the fixing frame 5, preventing it from easily breaking due to excessive extension length, further improving the stability of finished wire tension monitoring. Limiting the shape of one side of the push plate 7 effectively prevents wear on the finished wire, ensuring normal transmission and avoiding obstruction.

[0039] It should be noted that the functions to be achieved by each hardware component in this utility model are supported by a large number of mature technologies and belong to the prior art. The essence of this utility model is to optimize and combine existing hardware and its connection methods for specific application scenarios to meet the adaptation requirements of specific application scenarios and solve the problems raised in the background technology (without involving improvements to the internal software of the hardware).
