Description

Technical Field

[0001] This utility model relates to the field of textile machinery technology, and in particular to an automatic spindle end yarn cutting device for the yarn collection system of a spinning frame in a textile factory. Background Technology

[0002] In the current ring spinning machine's doffing system, each doffing leaves a certain number of yarn loops around the knurled area under the spindle cutter on the aluminum bushing. This yarn can be called the tail yarn or spindle tail yarn. During the spinning process, the tail yarn in the knurled area of ​​the spindle accumulates and thickens over time. After a period of time, this causes new yarn to become unstable and fall off the knurled area, preventing normal spinning. The machine must be stopped for manual tail yarn trimming. The downtime of the ring spinning machine and the labor costs of tail yarn trimming significantly contribute to the product cost, potentially leading to higher yarn costs.

[0003] Therefore, it is necessary to design a device that can be installed on the spinning machine's collection system to automatically cut the spindle tail yarn. Utility Model Content

[0030] Please see Figures 1 to 6 This embodiment provides an automatic spindle end yarn cutting device for a spinning machine collection system in a textile mill, which includes: a guide rail 1, a bracket 2 slidably connected to the guide rail 1, and a drive mechanism 3, a cutter mechanism 4, a yarn suction component 5, a control unit 6, a detection unit 7, and a power supply component 8 mounted on the bracket 2.

[0031] The automatic spindle foot tail yarn cutting device of this embodiment can be installed on the existing ring spinning frame collection system. For ease of explanation, a brief description of some structures of the existing ring spinning frame collection system is provided, such as... Figure 1 The diagram shows a portion of the structure of a conventional spinning machine doffing system, which includes a spindle 91, rotatable spindles 92 arranged sequentially along the length of the spindle 91, and a guide plate 93 through which multiple spindles 92 pass. The spindles 92 can be fitted onto spinning bobbins (not shown). By rotating the spinning bobbin, the yarn can be wound onto it. The traveler (not shown) is guided by the guide plate 93 to achieve high-speed and stable movement on the spinning machine, thereby ensuring uniform twisting and winding of the yarn. Under normal circumstances, the guide plate 93 moves from bottom to top. When the guide plate 93 moves to the top, the yarn on the spinning bobbin has been wound and the doffing operation can be performed. The lower part of the spindle 92 has a yarn cutting knife 921 and a knurling part 922. The knurling part 922 is used to wind one end of the yarn, and the yarn cutting knife 921 is used to cut the yarn between the knurling part 922 and the yarn bobbin when the yarn is doffed, so that the yarn bobbin can be doffed normally. The remaining yarn wound on the knurling part 922 is called the tail yarn. This part of the structure is a common structure of the existing spinning machine doffing system, and will not be described in detail.

[0032] In this embodiment, the guide rail 1 is mounted on the reinforcing bar 91 and extends linearly along the length of the reinforcing bar 91. The bracket 2 is connected to the guide rail 1 via a slider, allowing it to slide along the guide rail 1 with accurate positioning and smooth sliding.

[0033] The drive mechanism 3 drives the support 2 to slide along the guide rail 1. The cutter mechanism 4 cuts the tail yarn. The yarn suction component 5 sucks up the cut tail yarn. The control unit 6 is electrically connected to the drive mechanism 3, the yarn suction component 5, the detection unit 7, and the power supply component 8. The detection unit 7 detects the position of the ring rail plate of the spinning machine and the starting and reversing positions of the support. When the spinning machine's collection system is detected to be in a normal position, the control unit 6 can be operated to start the drive mechanism 3, causing the support 2 to slide along the guide rail 1. This allows the cutter mechanism 4 to sequentially cut the tail yarn of the knurled part 922 on each spindle 92 until the last spindle 92 is cut. The detection unit 7 detects the end position signal, and the drive mechanism 3 drives the support 2 to slide in the opposite direction along the guide rail 1, causing the cutter mechanism 4 to sequentially cut the tail yarn of the knurled part 922 on each spindle 92 again, ensuring a clean cut. At the same time as the drive mechanism 3 starts, the yarn suction component 5 also starts working, sucking up the cut tail yarn to prevent the yarn from flying around and causing pollution.

[0034] The power supply component 8 described in this embodiment is used to provide electrical energy to the drive mechanism 3, the yarn suction component 5, the control unit 6, and the detection unit 7, thereby eliminating the need for additional wires and power supplies and making it convenient to use.

[0035] As can be seen from the above settings, the automatic spindle end yarn cutting device in this embodiment can realize the function of automatically cutting the spindle end yarn without stopping the machine to cut the yarn, thus improving production efficiency and eliminating the need for manual yarn cutting, thereby reducing labor costs.

[0036] In this embodiment, the control unit 6 includes a main control board and a control panel connected to the main control board. The detection unit 7 includes a first position detection sensor 71, a second position detection sensor 72, a third position detection sensor 73, and a fourth position detection sensor 74. The first position detection sensor 71 is used to detect the height of the guide plate 93 of the spinning frame collection system. The second position detection sensor 72 is used to detect the bottom position of the doffing of the guide plate 93 of the spinning frame collection system. The third position sensor 73 is used to detect the starting position of the support 2. The fourth position sensor 74 is used to detect the reversing position of the support 2. After the spinning machine has spun for a certain period of time, the ring rail will reach a certain height. When the first position detection sensor 71 detects the ring rail 93, it indicates that the machine is ready to work and the tail yarn cutting operation can begin. At this time, the control panel displays "Preparing". The user can then click the start button on the control panel, and the main control board will control the drive mechanism 3 to start. When the bracket 2 moves along the guide rail 1 in the positive direction, and the third position detection sensor 73 detects the end position of the spinning machine's yarn collection system, the main control board will control the drive mechanism 3 to run in the reverse direction, causing the bracket 2 to move in the opposite direction along the guide rail 1. In this embodiment, the first position detection sensor 71, the second position detection sensor 72, the third position sensor 73, and the fourth position sensor 74 are all metal induction sensors.

[0037] Specifically, the blade holder mechanism 4 in this embodiment includes a telescopic cylinder 41, a pressure plate 42, a blade holder 43, and a blade 45. The telescopic cylinder 41 is mounted on the bracket 2. The pressure plate 42 and the blade holder 43 are both connected to the movable end of the telescopic cylinder 41. The pressure plate 42 is used to abut against the outer peripheral surface of the spindle seat (bottom of the spindle 93) of the spinning machine's collection system. The blade 45 is fixed on the blade holder 43. When the bracket 2 moves along the guide rail 1, the pressure plate 42 will abut against the outer peripheral surface of each spindle 92 in sequence. Because the installation positions of the spindles 92 on each spinning machine or on the same spinning machine may differ, the pressure plate 42 can be subjected to varying degrees of pressure. This varying degree of pressure causes the movable end of the telescopic cylinder 41 to retract by different distances, thus moving the cutter holder 43 backward. This prevents the blade 45 from colliding with the knurled part 922 of the spindle 92, which could damage the blade 45. In other words, through this setup, the position of the blade 45 can be automatically adjusted, and the distance between the blade 45 and the knurled part 922 of the spindle 92 can be adjusted in real time according to the differences in the installation positions of the spindle 92. Furthermore, by adjusting the installation position of the telescopic cylinder 41 on the bracket 2, the degree of pressure between the pressure plate 42 and the outer circumference of the spindle 92 can be adjusted. The clamping plate 42 is preferably a graphite copper plate, which has excellent self-lubricating properties. Graphite particles can form a stable solid lubricating film during friction, effectively reducing direct contact between metals, reducing friction and wear, and maintaining good lubrication even without external lubrication.

[0038] Preferably, the blade holder 43 in this embodiment includes a lower body 431, an upper body 432, a sliding seat 433, and a pressure plate 434. The lower body 431 is connected to the movable end of the telescopic cylinder 41. The upper body 432 and the lower body 431 are connected to each other, and the height between the upper body 432 and the lower body 431 is adjustable. The sliding seat 433 is slidably disposed on the top of the upper body 432. The pressure plate 434 presses the blade 45 onto the sliding seat 433.

[0039] The height between the upper seat 432 and the lower seat 431 is adjustable, thereby adjusting the height position of the blade 45 to adapt to the height of the knurled part 922 of different spindles 92. The sliding seat 433 can adjust the distance between the blade 45 and the knurled part of the spindle 92. The pressure plate 434 can press the blade 45 tightly to prevent the blade 45 from falling off.

[0040] Specifically, in this embodiment, the lower base 431 is provided with a plurality of connecting holes 4310 arranged sequentially in the vertical direction, and the upper base 432 is provided with screws 4320 that mate with the connecting holes 4310. By selecting a suitable connecting hole 4310 according to the required height of the blade 45 and locking the screws 4320 in, the upper base 432 and the lower base 431 can be adjusted to a suitable position.

[0041] Preferably, the edge of the blade 45 in this embodiment is provided with a plurality of serrations 451, and two adjacent serrations 451 are connected by an arc surface 452 or a beveled surface. The blade 45 provided in this way can cut and tear the yarn from shallow to deep, and the blade tip is subjected to uniform force and has a long service life.

[0042] Specifically, in this embodiment, the driving mechanism 3 includes a motor 31, a drive wheel 32, a movable base plate 33, and a pressing mechanism 34. The motor 31 is mounted on the movable base plate 33, the drive wheel 32 is mounted on the output shaft of the motor 31, and the pressing mechanism 34 is mounted on the bracket 2 and abuts against the movable base plate 33. The pressing mechanism 34 drives the movable base plate 33 to move towards the guide rail 1, so that the drive wheel 32 abuts against the guide rail 1. When the drive wheel 32 is pressed against the guide rail 1 by the pressing mechanism 34, the motor 31 rotates the drive wheel 32, which can drive the bracket 2 to slide along the guide rail 1. By releasing the pressing mechanism 34, the drive wheel 32 and the guide rail 1 can be relaxed, facilitating transport and disassembly on both sides of the spinning machine and between machines, realizing the sharing of one device with multiple machines.

[0043] Specifically, the clamping mechanism 34 described in this embodiment is a push-pull quick clamp, which is convenient to operate and use.

[0044] Preferably, the yarn suction component 5 in this embodiment includes a yarn suction box 51 and a yarn suction fan 52 disposed in the yarn suction box 51. The yarn suction box 51 has a yarn suction port 511 facing the cutter holder mechanism 4 on its outer side. When the yarn suction fan 52 is activated, the yarn suction port 511 generates suction, which can suck the cut tail yarn into the yarn suction box 51, facilitating manual collection after automatic tail yarn cutting.

[0045] Preferably, the power supply component 8 in this embodiment is a storage battery, which uses a storage battery to provide power, eliminating the need for various external connecting wires.

[0046] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
