Description

Technical Field

[0001] The invention relates to the field of sanitary products, and in particular to a manufacturing device for bamboo fiber knitted sanitary products. Background Art

[0002] Bamboo fiber, as the name implies, is made from the evergreen bamboo plant in nature. It is another regenerated green cellulose fiber after the successful development of soybean protein fiber in my country. Bamboo fiber has better hygroscopicity, air permeability and drapability than cotton fabrics. More importantly, it has natural antibacterial properties. The same number of bacteria observed under a microscope, the bacteria on cotton products have not changed, while the bacteria on bamboo fiber are killed by about 75% after 24 hours, which is incomparable to other textile raw materials. Therefore, bamboo fiber fabric layers have gradually been applied to the field of sanitary napkins. Bamboo fiber fabrics are woven using large circular knitting machines, but the existing knitting equipment has no alarm mechanism during the yarn conveying process. When the equipment stops, it is impossible to quickly determine whether the equipment is shut down or the yarn is broken. During maintenance, it is very cumbersome. At the same time, the woven fabrics need to be manually transported, which wastes labor. Therefore, it is necessary to propose a manufacturing equipment for bamboo fiber knitted sanitary products with alarm. Summary of the invention

[0003] The purpose of the present invention is to solve the problems in the background technology and provide a manufacturing device for bamboo fiber knitted sanitary products.

[0004] The above technical objectives of the present invention are achieved through the following technical solutions:

[0005] A production device for bamboo fiber knitted sanitary products includes a large circular machine frame and a yarn supply system, a weaving system, and a pulling and winding system installed on the large circular machine frame. An alarm mechanism is provided between the yarn supply system and the weaving system. The yarn supply system, the weaving system, and the pulling and winding system are existing technologies and are not described in detail in this case. An alarm mechanism is provided on each yarn. A reel transport device is also provided next to the large circular machine frame for transporting the reel that has passed through the pulling and winding system.

[0006] The present invention can detect whether the yarn is broken or the equipment is shut down during the conveying process through the alarm mechanism, so as to facilitate maintenance personnel to quickly carry out maintenance and overcome the problem of cumbersome maintenance of existing large circular knitting machines. At the same time, the finished roll with fabric can be transported by the roll transport device, making the whole equipment more convenient to use.

[0007] The alarm mechanism includes a first pressure wheel group and a second pressure wheel group which are sequentially arranged on the yarn, the first pressure wheel group and the second pressure wheel group are spaced a distance apart, and the first pressure wheel group and the second pressure wheel group each include two roller mechanisms which are arranged on both sides of the yarn, a fixed shaft is fixedly connected to the middle of the back of the roller mechanism, a first fixed disk is provided at the end of the fixed shaft through a bearing, and the first fixed disk is fixed on the frame of the large circular machine, a magnet is provided on the back of one of the roller mechanisms, a Hall sensor is provided at a position opposite to the first fixed disk and the magnet, and the Hall sensor is controlled by a controller, which is a prior art and will not be described in detail in this case.

[0008] In the present invention, when the yarn passes through the roller mechanism, the yarn moves forward to drive the roller mechanism to rotate. During the rotation process, each time the magnet passes through the Hall sensor, the Hall sensor believes that the roller mechanism has rotated one circle. When one of the Hall sensors does not detect the magnet after a period of time, it is detected that one of the roller mechanisms is not rotating, thereby judging that the yarn is broken and sending out an alarm signal of the breakage. When both Hall sensors do not detect the magnet, it is detected that the roller mechanisms of the first pressure wheel group and the second pressure wheel group are not rotating, thereby judging that the equipment is shut down and sending out an alarm signal of the shutdown. Therefore, the braiding machine can judge whether the yarn is broken or shut down during use, which is convenient for maintenance.

[0009] The roller mechanism includes a second fixed plate, an elastic ring is provided on the outer side of the second fixed plate, the elastic ring can be a rubber ring, the second fixed plate is provided with more than three limiting slide grooves along the circumferential direction, the limiting slide groove is arranged along the radial direction of the second fixed plate, a slide bar is provided in the limiting slide groove, a guide column is provided on the upper surface of the starting end of the slide bar, a rotating shaft is fixedly connected to the middle part of the second fixed plate, a passive gear is rotatably fixed on the rotating shaft through a bearing, an arc guide groove is provided at a position opposite to the guide column on the passive gear, and the guide column slides on the arc guide groove.

[0010] The invention drives the slide bar to slide in the arc guide groove by rotating the passive gear, thereby driving the slide bar to move in the limit slide groove in a direction close to or away from the center of the circle. When the elastic ring is far away from the yarn, the slide bar is driven to move in a direction away from the center of the circle, thereby expanding the elastic ring to achieve the purpose of expanding the diameter, thereby ensuring that the yarn can drive the rotation of the elastic ring.

[0011] An arc-shaped support piece is provided at the end of the slide bar, and the arc-shaped support piece is provided on the inner side of the elastic ring. A second limiting groove is provided on the outer side of the arc-shaped support piece, and a convex strip cooperating with the second limiting groove is provided on the inner side of the elastic ring.

[0012] The present invention increases the contact area between the elastic ring and the slide bar by using the arc-shaped support piece, thereby ensuring that the slide bar can support the elastic ring.

[0013] The invention enables the elastic ring to be detachably connected through the cooperation of the convex strip and the second limiting groove. After being in contact with the yarn for a long time, the elastic ring will be worn and needs to be replaced in time.

[0014] The limiting slide groove is a T-shaped slide groove, the slide bar slides in the T-shaped slide groove, the cross-section of the limiting slide groove is that the bottom width is greater than the opening width, and the guide column is arranged at the opening of the T-shaped slide groove, so that the slide bar will not fall out of the slide groove through the T-shaped slide groove.

[0015] The passive gear is meshed with a second active gear, and the second active gear is rotationally connected to the second fixed plate via a bearing. The second active gear can be controlled by a small motor, and the motor is fixed on the second fixed plate. The rotation of the motor drives the second active gear to rotate, thereby driving the passive gear to rotate.

[0016] Preferably, the reel transport device includes a vehicle plate, a fixed block is provided on the top of the vehicle plate, a first limiting groove is provided on the top of the fixed block to prevent the reel from rolling left and right, a wheel is provided at the bottom of the vehicle plate, a connecting shaft is fixedly connected between the wheels, a fixing seat is fixedly connected to the bottom of the vehicle plate, the connecting shaft is fixedly connected to the fixing seat through a bearing, a wheel driving device is connected to the connecting shaft, the wheel driving device includes a motor fixed to the bottom of the vehicle plate, the output shaft of the motor is connected to a first driving gear, a driven gear is fixedly connected to the connecting shaft, the first driving gear and the driven gear are connected by a chain, and the motor can be controlled by a button on the operating table, can be controlled by a remote control, and can also be controlled by language.

[0017] The present invention controls the motor to rotate so that the vehicle plate moves to the side of the large circular knitting machine frame, and then the reel is manually transported to the first limiting groove, and then the motor rotates again to transport the reel for easy transportation.

[0018] Preferably, raised particles for enhancing friction are provided on the outer side of the elastic ring to increase the friction so that when the yarn passes through the bottom of the elastic ring, it is ensured that the roller mechanism can be driven to rotate.

[0019] Preferably, the elastic ring is formed by an elastic strip, a circular hole is opened at the starting end of the elastic strip, and a clamping rod is fixedly connected to the end of the elastic strip, and the elastic ring can be easily disassembled through the cooperation of the clamping rod and the circular hole.

[0020] In summary, the beneficial effects of the present invention are:

[0021] 1. The present invention can detect whether the yarn is broken or the equipment is shut down during the conveying process through the alarm mechanism, so as to facilitate maintenance personnel to quickly perform maintenance, overcome the problem of cumbersome maintenance of existing large circular knitting machines, and at the same time, the finished roll with the fabric can be transported through the roll transport device, making the whole equipment more convenient to use;

[0022] 2. The present invention controls the motor to rotate so that the vehicle plate moves to the side of the large circular knitting machine frame, and then the reel is manually moved to the second limiting groove, and then the motor rotates again to transport the reel, which is convenient for transportation;

[0023] 3. In the present invention, when the yarn passes through the roller mechanism, the yarn moves forward to drive the roller mechanism to rotate. During the rotation process, each time the magnetic steel passes through the Hall sensor, the Hall sensor considers that the roller mechanism has rotated one circle. When one of the Hall sensors does not detect the magnetic steel after a period of time, it is detected that one of the roller mechanisms is not rotating, thereby judging that the yarn is broken, and sending out a broken alarm signal. When both Hall sensors do not detect the magnetic steel, it is detected that the roller mechanisms of the first pressure wheel group and the second pressure wheel group are not rotating, thereby judging that the equipment is shut down, and sending out a shutdown alarm signal, so that the braiding machine can judge whether the yarn is broken or shut down during use, which is convenient for maintenance;

[0024] 4. The present invention drives the slide bar to slide in the arc guide groove through the rotation of the passive gear, thereby driving the slide bar to move in the direction close to or away from the center of the circle in the limiting slide groove. When the elastic ring is far away from the yarn, the slide bar is driven to move in the direction away from the center of the circle, thereby expanding the elastic ring to achieve the purpose of expanding the diameter and ensuring that the yarn can drive the rotation of the elastic ring.
