Description
Technical Field
[0001] The utility model relates to the technical field of detection, in particular to a yarn knot detection device. Background Art
[0002] Yarn is a textile product processed from various textile fibers into a certain fineness. It is used for weaving, rope making, thread making, knitting and embroidery, etc. It is divided into short fiber yarn, continuous filament, etc. The connection between yarns is generally knotted.
[0003] With respect to the above-mentioned related technologies, the inventors believe that the following defects exist: the number of knots is an important basis for grading the appearance quality of yarn products. Among yarn products, there are relevant regulations on the number of knots for superior products. However, for a long time, the method of detecting knots has mostly been manual detection with the naked eye, which is not only prone to errors but also reduces work efficiency. Utility Model Content
[0004] In order to solve the above problems, the utility model provides a yarn knot detection device.
[0005] The above technical purpose of the utility model is achieved through the following technical solutions: a yarn knot detection device, including a base plate, a fixed rod is fixedly arranged on the upper surface of the base plate, a detection disk is sleeved on the outer wall of the fixed rod, a plurality of detection ports are opened through the upper surface of the detection disk, and the plurality of detection ports are of different sizes, a pressure sensor is fixedly arranged on the upper surface of the base plate, a first spring is fixedly arranged on the upper surface of the pressure sensor, the other end of the first spring is abutted against the bottom surface of the detection plate, and a sliding rod is fixedly arranged on the upper surface of the base plate.
[0006] By adopting the above technical solution, when the staff needs to detect the knot of the wire, the staff needs to put the coil on the slide bar. Then, the staff passes the wire through the corresponding detection port according to the size of the wire. At this time, the staff pulls the wire, so that the detection port detects the knot. When the knot is found, the detection disk moves upward, so that the detection disk and the first spring are separated from each other. At this time, the pressure sensor detects the change in the pressure of the first spring, and then reminds the staff. In this process, the staff does not need to detect with the naked eye, thereby improving the work efficiency of the staff.
[0007] Furthermore, a plurality of guide grooves are formed through the upper surface of the detection plate, and two mutually symmetrical guide rods are symmetrically fixedly provided on the upper surface of the bottom plate, and the guide rods and the guide grooves match each other.
[0008] By adopting the above technical solution, the guide rod limits the detection plate, thereby reducing the probability of the detection plate rotating during operation, thereby improving the stability of the device. In addition, the setting of multiple guide grooves reduces the difficulty of the staff selecting the detection port so that the thread head cannot be directly aligned with the detection port, thereby reducing the difficulty of the staff's work.
[0009] Furthermore, a support plate is fixedly installed on the upper surface of the fixed rod, and a mounting rod with an L-shaped cross-section is symmetrically installed on the upper surface of the support plate. Collection rollers are jointly rotated on the side walls of the two mounting rods that are close to each other, and a through hole is opened through the upper surface of the support plate.
[0010] By adopting the above technical solution, after the staff passes the thread end through the detection port, the staff needs to pass the thread end through the through hole and fix it to the collecting roller. Then, the staff rotates the collecting roller, so that the thread end is wound around the side wall of the collecting roller. In this process, the difficulty of collecting the yarn is reduced, thereby reducing the difficulty of the staff's work.
[0011] Furthermore, the upper surface of the support plate is symmetrically provided with sliding grooves, and sliders are slidably arranged in the two sliding grooves. Second springs are fixedly arranged on the side walls of the two sliders away from each other, and the other ends of the two second springs are respectively fixedly arranged on the inner walls of the two sliding grooves away from each other.
[0012] By adopting the above technical solution, when the staff needs to disassemble the collecting roller, the staff needs to slide the slider, and then the installation block slides with the slider, so that the installation rod and the collecting roller are separated from each other, thereby reducing the difficulty of the staff to disassemble the collecting roller. In addition, when the staff installs the collecting roller, the installation rod is connected to the collecting roller under the action of the first spring. During this process, the first spring limits the installation rod, thereby reducing the probability of the installation rod and the collecting roller being separated from each other, thereby improving the stability of the device.
[0013] Furthermore, blocking plates are sleeved on both ends of the collecting roller.
[0014] By adopting the above technical solution, the blocking plate reduces the probability of the yarn escaping from the collecting roller when the collecting roller collects the yarn, thereby improving the stability of the device.
[0015] Furthermore, an alarm light is installed on the upper surface of the base plate, and the alarm light is electrically connected to the pressure sensor.
[0016] By adopting the above technical solution, when the pressure sensor detects a change in pressure, the alarm light is triggered, and then the alarm light reminds the staff, thereby reducing the difficulty of the staff's work.
[0017] Furthermore, the fixing rod is a fixing rod made of PTFE material, and the detection disk is a detection disk made of PTFE material.
[0018] By adopting the above technical solution, the friction coefficient of PTFE is low, thereby reducing the probability that the friction coefficient is too high when the knot is found and the knot directly passes through the detection port and cannot trigger the pressure sensor, thereby improving the practicality of the device.
[0019] In summary, the utility model has the following beneficial effects:
[0020] 1. In this application, when the staff needs to detect the knot of the wire, the staff needs to put the coil on the sliding rod. Then, the staff passes the wire through the corresponding detection port according to the size of the wire. At this time, the staff pulls the wire, so that the detection port detects the knot. When the knot is found, the detection plate moves upward, so that the detection plate and the first spring are separated from each other. At this time, the pressure sensor detects the change in the pressure of the first spring, and then reminds the staff. During this process, the staff does not need to detect with the naked eye, thereby improving the work efficiency of the staff;
[0021] 2. In this application, the guide rod limits the detection plate, thereby reducing the probability of the detection plate rotating during operation, thereby improving the stability of the device. In addition, the setting of multiple guide grooves reduces the difficulty of the staff selecting the detection port so that the thread head cannot be directly aligned with the detection port, thereby reducing the difficulty of the staff's work;
[0022] 3. In this application, after the staff passes the thread end through the detection port, the staff needs to pass the thread end through the through hole and fix it to the collecting roller. Then, the staff rotates the collecting roller, so that the thread end is wound around the side wall of the collecting roller. In this process, the difficulty of collecting the yarn is reduced, thereby reducing the difficulty of the staff's work. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION
[0027] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application; obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments in the present application without making creative work are within the scope of protection of the present application.
[0028] like Figure 1-3 As shown, the embodiment of the present application discloses a yarn knot detection device, including a base plate 1, a fixed rod 11, a detection disk 12, a pressure sensor, a first spring 14, a slide bar 15, a guide rod 3, a support plate 4, a mounting rod 41, a collecting roller 42, a slider 5, a second spring 51 and an alarm light 7. The base plate 1 is a circular plate-shaped structure, and its axis is vertical. The fixed rod 11 is a round rod-shaped structure, and its axis coincides with the axis of the base plate 1. The detection disk 12 is a disc-shaped structure, and its axis coincides with the axis of the base plate 1. The detection disk 12 is sleeved on the outer wall of the fixed rod 11, and the upper surface of the detection disk 12 is penetrated by a plurality of detection ports 2, and the sizes of the detection ports 2 are different. The pressure sensor 13 is fixedly arranged on the upper surface of the base plate 1, one end of the first spring 14 is fixedly arranged on the upper surface of the pressure sensor 13, and the other end of the first spring 14 abuts against the bottom surface of the detection plate. The slide bar 15 is a round rod-shaped structure with a vertical axis. The slide bar 15 is fixedly arranged on the upper surface of the bottom plate 1 .
[0029] When the staff needs to detect the knot, the staff needs to put the coil on the slide bar 15. Then, the staff passes the corresponding detection port 2 according to the size of the thread. At this time, the staff pulls the thread, so that the detection port 2 detects the knot. When the knot is found, the detection plate 12 moves upward, so that the detection plate 12 and the first spring 14 are separated from each other. At this time, the pressure sensor 13 detects the change in the pressure of the first spring 14, and then reminds the staff. In this process, the staff does not need to detect with the naked eye, thereby improving the work efficiency of the staff.
[0030] A plurality of guide grooves 21 are formed through the upper surface of the detection plate 12 . The guide rod 3 is a round rod structure with a vertical axis. Two guide rods 3 are symmetrically arranged on the upper surface of the base plate 1 , and the guide rods 3 match the guide grooves 21 .
[0031] The guide rod 3 limits the detection disk 12, thereby reducing the probability of the detection disk 12 rotating during operation, thereby improving the stability of the device. In addition, the setting of multiple guide grooves 21 reduces the difficulty of the staff selecting the detection port 2 so that the thread head cannot be directly aligned with the detection port 2, thereby reducing the difficulty of the staff's work.
[0032] The support plate 4 is a rectangular plate-shaped structure, and the support plate 4 is fixedly arranged on the upper surface of the fixing rod 11, and a through hole 23 is formed through the upper surface of the support plate 4. The cross section of the mounting rod 41 is L-shaped, and two mounting rods 41 are provided and symmetrically mounted on the upper surface of the support plate 4. The collecting roller 42 is a round rod-shaped structure, and its axis is horizontal, and the two ends of the collecting roller 42 are respectively rotatably arranged on the side walls of the two mounting rods 41 close to each other.
[0033] After the staff passes the thread end through the detection port 2, the staff needs to pass the thread end through the through hole 23 and fix it to the collecting roller 42. Then, the staff rotates the collecting roller 42, so that the thread end is wound around the side wall of the collecting roller 42. In this process, the difficulty of collecting the yarn is reduced, thereby reducing the difficulty of the staff's work.
[0034] The upper surface of the support plate 4 is symmetrically provided with slide grooves 22, and the slider 5 is a rectangular block structure. Two sliders 5 are provided and are respectively slidably arranged in the two slide grooves 22. Two second springs 51 are provided, and one end of the two second springs 51 is respectively fixedly arranged on the side walls of the two sliders 5 away from each other, and the other end of the two second springs 51 is respectively fixedly arranged on the inner walls of the two slide grooves 22 away from each other.
[0035] When the staff needs to disassemble the collecting roller 42, the staff needs to slide the slider 5, so that the installation block slides with the slider 5, so that the installation rod 41 and the collecting roller 42 are separated from each other, thereby reducing the difficulty of the staff to disassemble the collecting roller 42. In addition, when the staff installs the collecting roller 42, the installation rod 41 is connected to the collecting roller 42 under the action of the first spring 14. In this process, the first spring 14 limits the installation rod 41, thereby reducing the probability of the installation rod 41 and the collecting roller 42 being separated from each other, thereby improving the stability of the device.
[0036] In order to improve the stability of the device, both ends of the collecting roller 42 are sleeved with blocking plates 6. The blocking plates 6 reduce the probability of the yarn escaping from the collecting roller 42 when the collecting roller 42 collects the yarn, thereby improving the stability of the device.
[0037] The warning light 7 is mounted on the upper surface of the base plate 1 , and the warning light 7 is electrically connected to the pressure sensor 13 .
[0038] When the pressure sensor 13 detects a change in pressure, the alarm light 7 is triggered, and the alarm light 7 reminds the staff, thereby reducing the difficulty of the staff's work.
[0039] In order to improve the practicality of the device, the fixing rod 11 is made of PTFE material, and the detection disk 12 is made of PTFE material. PTFE has a low friction coefficient, which reduces the probability that the friction coefficient is too high when the knot is found and the knot directly passes through the detection port 2 and cannot trigger the pressure sensor 13, thereby improving the practicality of the device.
[0040] The working principle of a yarn knot detection device in this embodiment is as follows: when the staff needs to detect the yarn knot, the staff needs to put the coil on the slide bar 15. Then, the staff passes the corresponding detection port 2 and the through hole 23 according to the size of the thread and fixes it on the side wall of the collecting roller 42. At this time, the staff rotates the collecting roller 42, so that the thread is wound around the side wall of the collecting roller 42. During this process, the detection port 2 detects the knot. When a knot is found, the detection disk 12 moves upward, so that the detection disk 12 and the first spring 14 are separated from each other. At this time, the pressure sensor 13 detects the change in the pressure of the first spring 14, and then reminds the staff. During this process, the staff does not need to detect with the naked eye, thereby improving the work efficiency of the staff.
[0041] The above is only a preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
