[0002] The center group of the knitting machine is a key component of the knitting machine, which is mainly composed of a triangle device, a sinker and a yarn guide. This center group plays a vital role in the knitting process. Specifically, the triangle device can guide and control the movement trajectory of the knitting needles to ensure that the knitting needles work at the correct position and time; the sinker is responsible for controlling the position of the yarn when the knitting needles rise to prevent them from falling off or misaligned; and the yarn guide is used to guide the yarn into the knitting needles to ensure that the yarn can be accurately woven into the fabric. The design and performance of the knitting machine center group directly affect the quality and production efficiency of the knitted fabric. A high-quality center group should be able to ensure the stability of the needle movement, the accuracy of the yarn control and the high efficiency of the production efficiency. Therefore, in the manufacturing and maintenance process of the knitting machine, the selection and debugging of the center group are very important;

[0010] Preferably, a placement plate has four racks arranged on the outer side of its bottom, and the outer sides of the four racks are meshedly connected with transmission gears, and the output ends of the four transmission gears are wound and connected with first pull ropes, and the outer ends of the four first pull ropes are connected to moving rods through guide wheels, and the interiors of the four transmission gears are slotted with torsion springs, and the four torsion springs have the same structure, and the outer ends of the four torsion springs are connected to the inner wall of the base, and the positions of the four transmission gears after rotation can be elastically reset by the elastic force of the four torsion springs themselves, thereby facilitating the elastic reset of the position of the placement plate.
[0011] Preferably, the base has four tension springs disposed in an internal groove, and the four tension springs are disposed at equal intervals, and the outer ends of the four tension springs are connected to the moving rods, so that the positions of the four moving rods can be elastically reset after movement by the elastic force of the four tension springs themselves.

[0014] Compared with the prior art, the beneficial effects of the utility model are as follows:
[0015] (1) Four moving rods are slidably installed by slotting the surface of the base, and then limit rods are welded and installed at the tops of the four moving rods. When the center group body needs to be quickly installed, it is only necessary to pull the limit rods arranged at the tops of the four moving rods to extend through the bottom inner side of the center group body. At this time, the installed center group body can be quickly installed and positioned, avoiding the phenomenon that the center group body becomes loose and falls off due to vibration generated by use in the later stage, thereby improving the use stability of the center group body;
[0016] (2) A placement plate is installed by sliding through the internal groove of the base, and then the placement plate is extended to the upper outer side of the base, and then the placement plate is connected to the bottom outer wall of the center group body through a buffer pad.

At this time, the racks arranged on both sides of the placement plate will simultaneously drive the first pull ropes wound around the output ends of the two transmission gears to pull the four moving rods through the guide wheels to move the positions. Then, the limit rods connected to the top ends of the four moving rods can be driven to position and clamp the installed center group body, so as to prevent the center group body from loosening and falling off during use in the later stage.
[0018] (4) A dust removal ring is installed at the outer end of the center group body, and the wire bundle can be transported to the knitting machine through the dust removal ring for knitting processing while the knitting wire is being transported.

[0019] (5) When knitting threads of different diameters need to be transported, it is only necessary to pull the pull rod to move the position. At this time, the second pull rope connected to the outer end of the pull rod will pull the two limit blocks through the guide wheel to retract and move, and then the installation rod can be separated from the dust removal ring. Subsequently, the installation rod can be pulled to slide through the inside of the dust removal ring, and finally, the elastic force of the two reset springs can be pulled to automatically pop out the two limit blocks into the limit grooves opened inside the dust removal ring, which saves time and effort.

DETAILED DESCRIPTION
[0028] 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.
[0029] This utility provides the following technical solutions:
[0030] Embodiment 1, in order to solve the problem that the disassembly and replacement operation of the existing center group body 2 is very cumbersome, discloses:
[0031] A base 1, wherein a center group body 2 is installed through a groove inside the base 1, a dust removal ring 3 is installed on the top of the center group body 2, and a circle of support seats 6 is arranged on the outer side of the bottom of the base 1;
[0032] It also includes: a base 1, a placement plate 9 is installed through the internal groove, and the top of the placement plate 9 extends through to the outside of the top of the base 1, and a center group body 2 is placed above the placement plate 9, and the base 1 has a circle of moving rods 4 slidably installed through the upper groove, and the four moving rods 4 have the same structure, and the top of the circle of moving rods 4 are all installed with limiting rods 5, and the outer ends of the four limiting rods 5 extend through to the bottom inner side of the center group body 2.
[0033] like Figure 1-Figure 2 As shown, after the center group body 2 is placed inside the base 1, the limiting rods 5 installed on the top of the four moving rods 4 are pulled to extend through the bottom inner side of the center group body 2. At this time, the installed center group body 2 can be quickly clamped and positioned to avoid the center group body 2 from loosening and falling off due to vibration during later use, thereby improving the stability of the center group body 2.
[0034] Embodiment 2 is different from Embodiment 1 in that the placed center group body 2 can be automatically clamped and positioned, and discloses:
[0035] A placement plate 9 is provided, on the top of which a buffer pad 10 is fitted and connected, and the buffer pad 10 is made of rubber material, and the top of the buffer pad 10 is fitted and connected to the bottom outer side of the center group body 2; a placement plate 9 is provided, on the bottom outer side of which four racks 12 are arranged, and the outer sides of the four racks 12 are meshed and connected with transmission gears 11, and the output ends of the four transmission gears 11 are wound and connected with first pull ropes 8, and at the same time, the outer ends of the four first pull ropes 8 are connected to the moving rod 4 through guide wheels, the insides of the four transmission gears 11 are grooved with torsion springs 13, and the four torsion springs 13 have the same structure, and the outer ends of the four torsion springs 13 are connected to the inner wall of the base 1, and the base 1 is grooved with four tension springs 7, and the four tension springs 7 are arranged at equal intervals, and the outer ends of the four tension springs 7 are connected to the moving rod 4.
[0036] like Figure 1-Figure 4 As shown, after the center group body 2 is placed on the placement plate 9, the buffer pad 10 arranged on the placement plate 9 will increase the anti-seismic buffering performance between the base 1 and the center group body 2, avoiding the center group body 2 from being damaged due to vibration, and improving the service life of the center group body 2. Then, the center group body 2 will also drive the placement plate 9 to descend by its own weight, and then the four racks 12 arranged on the outside of the placement plate 9 will also drive the four transmission gears 11 to rotate at the same time. At this time, the first pull rope 8 wound around the output end of the four transmission gears 11 will also pull the four moving rods 4 to move through the guide wheel at the same time, so that the placed center group body 2 can be automatically clamped and positioned, which is more practical.
[0037] When the central group body 2 needs to be quickly disassembled, assembled and replaced, it is only necessary to manually pull the moving rod 4 to move the position, and then the limiting rod 5 can be driven to separate from the central group body 2. At this time, the elastic force of the four torsion springs 13 can elastically reset the position of the four rotating transmission gears 11, thereby elastically resetting the placement plate 9 after being squeezed and lowered, and the operation is more time-saving and labor-saving.
[0038] like Figure 1-Figure 7 As shown, when the knitting thread is conveyed to the knitting machine through the dust removal ring 3 for use, a circle of arc-shaped plates 15 arranged on the inner side of the dust removal ring 3 will continuously clean the conveyed knitting thread through a circle of cleaning brushes 16, so as to prevent dust and impurities from sticking to the surface of the knitting thread and affecting the subsequent weaving processing. It can also prevent the conveyed knitting thread from being entangled and knotted during transportation, thereby improving the stability of the knitting thread transportation.
[0039] Embodiment 3 is different from Embodiment 2 in that dust and impurities on the surface of the conveyed knitted yarn can be continuously conveyed and cleaned, and discloses:
[0040] The dust removal ring 3 has grooves all around its interior through which four mounting rods 14 are slidably installed, and the inner ends of the four mounting rods 14 are all installed with arc plates 15 by screws, and the inner sides of the four arc plates 15 are provided with cleaning brushes 16, and the inner sides of the four cleaning brushes 16 are connected to the outer wall of the knitted thread, the mounting rod 14 has limit blocks 17 slidably installed on both the upper and lower sides of its inner end through reset springs 18, and the two limit blocks 17 are symmetrically arranged about the transverse center line of the mounting rod 14, and the outer ends of the two limit blocks 17 are both connected to the limit grooves opened in the dust removal ring 3, the mounting rod 14 has a pull rod 20 slidably installed in the outer groove, and the outer end of the pull rod 20 is connected to a second pull rope 19, and the outer end of the second pull rope 19 is connected to two limit blocks 17 through a guide wheel.
[0041] like Figure 1-Figure 7 As shown, when the knitting thread is conveyed to the knitting machine through the dust removal ring 3 for use, a circle of arc-shaped plates 15 arranged inside the dust removal ring 3 will continuously clean the conveyed knitting thread through a circle of cleaning brushes 16, so as to prevent dust and impurities from adhering to the surface of the knitting thread and affecting the subsequent knitting processing, and also to prevent the conveyed knitting thread from being entangled and knotted during the conveying, thereby improving the stability of the knitting thread conveying;
[0042] When it is necessary to transport and clean knitting threads of different diameters, it is only necessary to manually pull the pull rod 20 to drive the second pull rope 19 to pull the two limit blocks 17 through the guide wheel to retract and move. At this time, the mounting rod 14 can be separated from the dust removal ring 3, and then the mounting rod 14 is pulled to move its position inside the dust removal ring 3. When it is adjusted to a suitable position, the two return springs 18 will automatically pop out the two limit blocks 17 into the limit grooves opened inside the dust removal ring 3 with their own elastic force, and then the adjusted circle of arc plates 15 can be positioned and fixed, which saves time and effort.
