Description

Technical Field

[0001] The utility model relates to the technical field of spinning machines, in particular to an anti-deviating yarn breakage detection mechanism for a spinning machine. Background Art

[0002] The chenille spinning machine is a device used to produce chenille yarn. The general structure includes: a frame, a rotating head, a wire feeding structure, a roller structure and a spindle mechanism. During the production process of chenille yarn, yarn breakage or poor yarn quality may occur. In the case of yarn breakage, the spinning machine continues to work without the supervision of staff. Since the broken yarn is not pulled by the equipment, the yarn that continues to be transported by the spinning machine will become knotted and clumped, blocking the normal use of the equipment.

[0003] As disclosed in the public document with application number 202121173742.6, a yarn break detection mechanism of an eddy current spinning machine is disclosed, and the utility model includes a frame; the frame is in an "L" shape, and a through hole is provided in the middle position above the front end of the frame, and a perforation is provided in the middle position of the bottom. Since a rectangular groove is provided in the middle position of the adjusting frame, and two slide rail grooves are symmetrically provided on the left and right sides of the rectangular groove, and the rack A slider is slidably connected in the slide rail groove on the right side of the adjusting frame, when the rack A moves downward in the rectangular groove of the adjusting frame, the rack A is prevented from deviating from the track in the adjusting frame. However, the yarn break detection mechanism of the spinning machine, when the spinning line is transported, the line of the spinning line is passed through the tube to prevent the spinning line from being deviated. However, after the spinning line passes through a certain tortuosity, it enters the tube body, and the spinning line contacts the opening edge of the tube body. As the spinning line continues to move, the spinning line rubs against the edge of the tube body, thereby increasing the probability of the spinning line breaking, which is not conducive to the effective and stable transportation of the spinning line.

[0004] Therefore, in view of this, the existing structural deficiencies are studied and improved, and an anti-deviating yarn break detection mechanism for a spinning machine is proposed. Utility Model Content

[0005] The utility model aims to provide a yarn breakage detection mechanism for a spinning machine with an anti-deviating function, so as to solve the problems raised in the above-mentioned background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an anti-deviated yarn break detection mechanism for a spinning machine, comprising an assembly frame, a transverse plate is fixedly installed on the middle part of the front side of the surface of the assembly frame, a control box is fixedly installed on the front side above the surface of the assembly frame, an anti-slip mechanism is installed on the top of the assembly frame, a wire break protection mechanism is arranged on the surface of the transverse plate, a guide wheel is arranged above the transverse plate and below the anti-slip mechanism, and a slot is opened on the rear side above the surface of the assembly frame.

[0007] Preferably, the anti-slip mechanism comprises a protective cover fixedly mounted on the top of the assembly frame, a cross bar is fixedly mounted on the front end of the outer surface of the protective cover, and a protective cover is also fixedly mounted on the front end of the cross bar.

[0008] Preferably, the anti-slip mechanism also includes cams rotatably arranged above the inner surfaces of the two protective covers, a concave wheel rotatably arranged below the cam on the inner surface of the protective cover, and a central protruding portion of the cam is rotatably embedded in a central recessed portion of the concave wheel.

[0009] Preferably, the wire breakage protection mechanism includes a movable rod slidingly arranged through the middle of the horizontal plate, a rotating plate rotatably arranged at the bottom end of the movable rod, the middle part of the rotating plate is rotatably connected to the surface of the horizontal plate below through a vertical rod, and the rear end of the rotating plate is rotatably arranged on the lifting rod.

[0010] Preferably, the wire breakage protection mechanism further comprises a fixing plate fixedly mounted on the upper rear side of the assembly frame surface, a push rod is slidably provided through the surface of the fixing plate, and a limit plate is fixedly mounted on the rear end of the push rod.

[0011] Preferably, the wire breakage protection mechanism further comprises a spring which is fixedly mounted on the front side of the limiting plate surface and sleeved on the outside of the push rod, and the front end of the spring is fixedly connected to the fixing plate.

[0012] Preferably, the upper end of the movable rod is rotatably connected to the guide wheel, and the bottom end of the lifting rod passes through the limiting plate and is inserted into the slot.

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

[0014] 1. The utility model is provided with an anti-slip mechanism, a protective cover, a cross bar, a cam and a concave wheel. The yarn is placed on the concave part in the middle of the concave wheel, and the cam is used to limit the yarn above, so that the yarn is located in the closed gap in the middle of the concave wheel and the cam. Therefore, when the spinning machine winds the yarn, the yarn on the assembly frame can be prevented from deviating and falling off, which greatly improves the stability of the yarn transportation during the processing. In addition, the cam and the concave wheel can both rotate to prevent the yarn from sliding on the edge of the assembly frame surface or other limiting devices, thereby preventing the yarn from being worn and broken;

[0015] 2. The utility model is provided with a wire breakage protection mechanism, a movable rod, a rotating plate, a lifting rod, a fixed plate, a push rod, a limit plate, a spring, a slot and a guide wheel. When the yarn is transported normally, the yarn passes under the guide wheel and is lifted up to make the movable rod in an upward moving state. At this time, the rotating plate is placed horizontally, the lifting rod passes through the limit plate and is inserted into the slot to stretch the spring. When the yarn breaks, the yarn loses the support of the guide wheel, the movable rod falls under the influence of gravity, and pushes the front end of the rotating plate to move downward. At this time, the rear end of the rotating plate will tilt, thereby pulling the lifting rod out of the slot and moving upward, releasing the obstruction of the limit plate, and under the pulling force of the spring, the limit plate pushes the push rod forward, and the emergency stop button on the control box is pressed, so that the spinning machine stops working. The overall device can automatically perform emergency stop control on the spinning machine in an unattended state to prevent the spinning machine from continuing to transport yarn when the yarn breaks, resulting in knotting and clumping, which blocks the normal use of the equipment.

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] like Figure 1-Figure 2As shown, an anti-deviating yarn break detection mechanism for a spinning machine includes an assembly frame 1, a horizontal plate 2 is fixedly installed in the middle of the front side of the surface of the assembly frame 1, a control box 3 is fixedly installed on the front side above the surface of the assembly frame 1, an anti-slip mechanism 4 is installed on the top of the assembly frame 1, a broken wire protection mechanism 5 is arranged on the surface of the horizontal plate 2, a guide wheel 7 is arranged above the horizontal plate 2 and below the anti-slip mechanism 4, and a slot 6 is opened on the rear side above the surface of the assembly frame 1.

[0023] By adopting the above technical solution, the anti-drop mechanism 4 can prevent the yarn on the assembly frame 1 from deflecting and falling off, and avoid wear and breakage; an emergency stop button is provided on the control box 3, and the control box 3 is used to control the spinning machine.

[0024] Furthermore, the anti-slip mechanism 4 includes a protective cover 401 fixedly mounted on the top of the assembly frame 1 , a cross bar 402 is fixedly mounted on the front end of the outer surface of the protective cover 401 , and the protective cover 401 is also fixedly mounted on the front end of the cross bar 402 .

[0025] By adopting the above technical solution, the protective cover 401 is used to install the rolling element in the anti-slip mechanism 4.

[0026] Furthermore, the anti-slip mechanism 4 also includes cams 403 rotatably arranged above the inner surfaces of the two protective covers 401, and a concave wheel 404 rotatably arranged on the inner surface of the protective cover 401 below the cam 403, and the middle protruding part of the cam 403 is rotatably embedded in the middle concave part of the concave wheel 404.

[0027] By adopting the above technical solution, the protrusion in the middle of the cam 403 is located in the groove of the cam wheel 404, but is not completely fitted into the groove. A gap is still left in the middle for the yarn to run, so that the yarn can pass through the middle gap, and effective positioning is performed up, down, left, and right to prevent the yarn from deviating and falling off; the cam 403 and the cam wheel 404 can both rotate independently, so that when the yarn passes through the middle gap, the sliding friction can be converted into rolling friction, reducing the friction of the contact surface and preventing the yarn from being worn and broken during running.

[0028] like Figure 3-Figure 4 As shown, the wire break protection mechanism 5 includes a movable rod 501 that is slidably arranged in the middle of the horizontal plate 2, and a rotating plate 502 is rotatably arranged at the bottom end of the movable rod 501. The middle part of the rotating plate 502 is rotatably connected to the surface of the horizontal plate 2 below through a vertical rod, and the rear end of the rotating plate 502 is rotatably arranged on the lifting rod 503.

[0029] By adopting the above technical solution, the rotating plate 502 is assembled in a seesaw-like manner, and the movable rod 501 is pressed down to make the front end of the rotating plate 502 rotate downward, and the rear end will pull the lifting rod 503 to lift up.

[0030] Furthermore, the wire breakage protection mechanism 5 also includes a fixing plate 504 fixedly installed on the upper rear side of the assembly frame 1 surface, a push rod 505 is slidably provided on the surface of the fixing plate 504 , and a limit plate 506 is fixedly installed on the rear end of the push rod 505 .

[0031] By adopting the above technical solution, the push rod 505 is horizontally opposite to the emergency stop button of the control box 3, and the fixing plate 504 ensures that the push rod 505 can accurately move and press the emergency stop button.

[0032] Furthermore, the wire breakage protection mechanism 5 also includes a spring 507 fixedly mounted on the front side of the surface of the limiting plate 506 and sleeved on the outside of the push rod 505 , and the front end of the spring 507 is fixedly connected to the fixing plate 504 .

[0033] By adopting the above technical solution, the spring 507 can utilize the limiting plate 506 to drive the push rod 505 to move.

[0034] Furthermore, the upper end of the movable rod 501 is rotatably connected to the guide wheel 7 , and the bottom end of the lifting rod 503 passes through the limiting plate 506 and is inserted into the slot 6 .

[0035] By adopting the above technical solution, the yarn is wound around the bottom of the guide wheel 7, and the entire wire breakage protection mechanism 5 is supported by the yarn using the guide wheel 7; the bottom end of the lifting rod 503 is limited by the slot 6 to prevent the lifting rod 503 from rotating left and right, and at the same time passes through the limiting plate 506, that is, the backward moving limiting plate 506 is fixed.

[0036] Working principle: when using the anti-deviating yarn break detection mechanism for a spinning machine, first, the yarn passes through the closed gap in the middle of the rear concave wheel 404 and the cam 403, bypasses the bottom of the guide wheel 7, and then passes through the closed gap in the middle of the front concave wheel 404 and the cam 403 to connect with the roller body of the spinning machine. The yarn lifts the guide wheel 7, so that the movable rod 501 is in an upward state. At this time, the rotating plate 502 is placed horizontally, and the lifting rod 503 passes through the limiting plate 506 and is inserted into the slot 6, so that the spring 507 is stretched, and the push rod 505 is located at the rear side and does not contact the control box 3. Then the textile machine can be started, and the textile machine continuously pulls the yarn to move. The yarn rests on the concave part in the middle of the concave wheel 404, and is limited by the cam 403 above. Therefore, when the spinning machine winds the yarn, the yarn on the assembly frame 1 can be prevented from The cam 403 and the concave wheel 404 can rotate to prevent the yarn from sliding on the edge of the assembly frame 1 or other limiting devices, thereby causing wear and breakage. If the yarn is still broken during transportation, the yarn loses the support of the guide wheel 7, and the movable rod 501 falls under the influence of gravity, pushing the front end of the rotating plate 502 to move downward. At this time, the rear end of the rotating plate 502 will rise, thereby pulling the lifting rod 503 out of the slot 6 and moving upward, releasing the obstruction of the limiting plate 506. Under the pulling force of the spring 507, the limiting plate 506 pushes the push rod 505 forward, pressing the emergency stop button on the control box 3, thereby stopping the spinning machine. The overall device can automatically perform emergency stop control on the spinning machine when it is unattended. This is the working principle of the anti-deviate yarn break detection mechanism for the spinning machine.
