Description

Technical Field

[0001] This utility model belongs to the field of mechanical technology and relates to a simple wire feeding mechanism for threading plates, particularly a simple wire feeding mechanism for threading plates that is simple in structure and easy to operate. Background Technology

[0002] When a computerized flat knitting machine is knitting, the fabric is initially light and requires a tensioning device to smoothly complete the subsequent knitting work. Existing designs usually include a starting device (threading plate assembly) to tension the fabric at the beginning of the knitting process, thereby reducing yarn consumption.

[0003] Most existing bottom-raising devices use a wire storage tray combined with a wire feeding and take-up mechanism, which is relatively complex in structure, uses many parts, has high production costs, and is difficult to install and maintain later.

[0004] In summary, to address the shortcomings of existing computerized flat knitting machine bottom-raising devices, this utility model designs a simple and easy-to-operate wire feeding mechanism for threading plates. Summary of the Invention

[0005] To address the problems existing in the prior art, this utility model provides a simple wire feeding mechanism for threading plates that is simple in structure and easy to operate.

[0006] The objective of this utility model can be achieved through the following technical solution: A simple wire feeding mechanism for a threading plate, comprising: The base plate is mounted on the bottom of the wire guide plate via a bracket. A motor is fixed to the back of the base plate, and the output shaft of the motor passes through the base plate and is fixed to a drive gear. The wire feeding assembly is arranged in two groups in parallel. The two wire feeding assemblies are located on the surface of the base plate. Each group of wire feeding assemblies includes two pairs of wire feeding units, and each wire feeding unit includes wire feeding wheels and wire pressing wheels that fit together. Each wire feeding wheel and wire pressing wheel is distributed along a straight line. The wire feeding pipe passes through each wire feeding unit and is connected to the wire threading plate. A steel wire is threaded inside the wire feeding pipe. The motor can drive each wire wheel to rotate and further drive the steel wire to move along the wire feeding pipe into or out of the wire threading plate.

[0007] As a further improvement to this case, the aforementioned driving gear is located between the two wire feeding assemblies, and two driven gears corresponding to the two wire feeding assemblies are symmetrically arranged on both sides of the driving gear.

[0008] As a further improvement in this case, each wire feeding wheel is equipped with a primary gear, and each wire pressing wheel is equipped with a secondary gear that meshes with the corresponding primary gear. The aforementioned driving gear meshes with two adjacent primary gears between the two wire feeding assemblies, and each driven gear meshes with two primary gears in the corresponding wire feeding assembly.

[0009] As a further improvement to this invention, each wire feeding wheel is connected to the base plate via a fixed shaft, and each wire pressing wheel is connected to the base plate via a movable shaft. An annular groove is provided on the circumferential surface of each wire wheel.

[0010] As a further improvement in this case, each movable shaft is fitted with a swing rod, and each swing rod is connected to the base plate by a stepped bolt. Each swing rod can rotate around the corresponding stepped bolt and drive the corresponding movable shaft to offset. The base plate has several adjustment holes that correspond one-to-one with each movable shaft.

[0011] As a further improvement to this invention, a screw is installed on one of the rocker arms in each wire feeding assembly, and a hinge bolt is installed on the other rocker arm. The screw and the hinge bolt are connected by a tension spring.

[0012] As a further improvement in this case, the aforementioned hinge bolts are set to two, and the two hinge bolts are set perpendicular to each other.

[0013] As a further improvement to this invention, the wire feeding conduit includes a front conduit, a rear conduit, and several intermediate conduits located between the front conduit and the rear conduit. One of the aforementioned intermediate conduits is provided between two adjacent wire feeding units, and each conduit is fixed to the base plate by a stud.

[0014] As a further improvement in this case, a detection bolt is fixed between the intermediate conduit and the rear conduit, and the top of the detection bolt has a detection hole for a steel wire to pass through.

[0015] Compared with the prior art, this utility model has a reasonable structural design and is easy to operate. By setting multiple sets of wire feeding components, it is easy for the steel wire to move back and forth. At the same time, it can increase the friction when the steel wire retracts, which helps the steel wire to be recovered and ensures that the steel wire is smoothly returned to the designated position. The setting of the swing arm makes it easy to adjust the distance between the pressure wheel and the corresponding wire feeding wheel, which facilitates the smooth movement of the steel wire.

Detailed Implementation

[0022] The technical solution of this utility model will be further described below with reference to the embodiments and accompanying drawings.

[0023] like Figures 1 to 5 As shown, the simple wire feeding mechanism for this wire threading board includes: The base plate 10 is mounted on the bottom of the wire guide plate 16 via the bracket 15. A motor 13 is fixedly mounted on the back of the base plate 10. The output shaft of the motor 13 passes through the base plate 10 and is fixedly connected to the drive gear 11. The wire feeding assembly is arranged in two groups in parallel. The two wire feeding assemblies are located on the surface of the base plate 10. Each group of wire feeding assemblies includes two pairs of wire feeding units 20, and each wire feeding unit 20 includes a wire feeding wheel 21 and a wire pressing wheel 22 that are in contact with each other. Each wire feeding wheel 21 and wire pressing wheel 22 are distributed along a straight line. The wire feeding pipe passes through each wire feeding unit 20 and is connected to the wire threading plate 16. A steel wire is threaded inside the wire feeding pipe. The motor 13 can drive each wire wheel to rotate and further drive the steel wire to move along the wire feeding pipe into or out of the wire threading plate 16.

[0024] Most existing bottom-raising devices use a wire storage tray combined with a wire feeding and take-up mechanism, which is relatively complex in structure, uses many parts, has high production costs, and is difficult to install and maintain later.

[0025] Therefore, this utility model provides a simple wire feeding mechanism for threading plates. By setting multiple sets of wire feeding components, it facilitates the reciprocating movement of the steel wire and achieves the purpose of wire feeding and retraction. At the same time, it can increase the friction when the steel wire retracts, which helps the steel wire to be recycled and ensures that the steel wire is smoothly returned to the designated position. The structure is simple and the operation is convenient.

[0026] Specifically, in this embodiment, two sets of wire feeding assemblies are preferably used to transport the steel wire. In fact, a flexible hose (not shown in the figure) is also provided at the bottom of the threading plate 16 to facilitate the storage of the steel wire. During operation, the motor 13 starts, driving the wire wheels on the two sets of wire feeding assemblies to rotate, which in turn drives the wire feeding units 20 to move along the wire feeding pipe until it moves to the designated position on the threading plate 16, which facilitates the subsequent lifting work.

[0027] Preferably, each wire feeding assembly includes two pairs of wire feeding units 20. Each wire feeding unit 20 consists of wire feeding wheels 21 and wire pressing wheels 22 that are in contact with each other. That is, in this utility model, four pairs of wire feeding units 20 are set to feed the steel wire. The wire feeding wheels 21 are arranged in a row, and the wire pressing wheels 22 are also arranged in a row. When the steel wire is actually moving, it passes between the wire feeding wheels 21 and the wire pressing wheels 22 on the wire feeding unit 20, that is, the steel wire passes between the two rows of wire wheels.

[0028] Preferably, the driving gear 11 is located between the two wire feeding assemblies, and two driven gears corresponding to the two wire feeding assemblies are symmetrically arranged on both sides of the driving gear 11.

[0029] Furthermore, each wire feeding wheel 21 is fitted with a primary gear 41, and each wire pressing wheel 22 is fitted with a secondary gear 42 that meshes with the corresponding primary gear 41. The aforementioned driving gear 11 is meshed with two adjacent primary gears 41 between the two wire feeding assemblies, and each driven gear is meshed with two primary gears 41 in the corresponding wire feeding assembly.

[0030] In this embodiment, the wire feeding wheel 21 and the wire pressing wheel 22 are respectively equipped with corresponding primary gears 41 and secondary gears 42, and the primary gears 41 and secondary gears 42 located on the same wire feeding unit 20 are meshed with each other.

[0031] Preferably, the drive gear 11 is located between the two wire feeding assemblies, and in particular, it is meshed with the first-stage gear 41 of the two adjacent wire feeding wheels 21 between the two wire feeding assemblies, so that when the motor 13 drives the drive gear 11 to rotate, it can drive the corresponding two first-stage gears 41 to rotate. Further preferably, two driven gears are symmetrically arranged on both sides of the driving gear 11. The two driven gears correspond to two sets of wire feeding assemblies, and the driven gears are meshed with the first-stage gears 41 on the two wire feeding wheels 21 in their respective wire feeding assemblies. When the driving gear 11 drives the corresponding first-stage gear 41 to rotate, it further drives the two driven gears to rotate, and then drives the other two first-stage gears 41 in the two sets of wire feeding assemblies to rotate; each first-stage gear 41 then drives each second-stage gear 42 to rotate.

[0032] Therefore, by adopting the gear transmission structure described above, it is possible to achieve that when the motor 13 starts, it drives the four wire feeding units 20 to operate simultaneously, thereby driving the steel wire to move.

[0033] Preferably, each wire feeding wheel 21 is connected to the base plate 10 via a fixed shaft 23, and each wire pressing wheel 22 is connected to the base plate 10 via a movable shaft 24. An annular groove 26 is provided on the circumferential surface of each wire wheel.

[0034] Furthermore, each movable shaft 24 is fitted with a rocker arm 25, and each rocker arm 25 is connected to the base plate 10 by a step bolt 51. Each rocker arm 25 can rotate around the corresponding step bolt 51 and drive the corresponding movable shaft 24 to offset. The base plate 10 has multiple adjustment holes 14 that correspond one-to-one with each movable shaft 24.

[0035] In this embodiment, the wire feeding wheel 21 is preferably fixedly connected to the base plate 10 via the fixed shaft 23, that is, the wire feeding wheel 21 only rotates in the circumferential direction and the installation position remains unchanged, while the wire pressing wheel 22 is movably connected to the base plate 10 via the movable shaft 24. In actual operation, the pressure on the steel wire can be adjusted by adjusting the wire pressing wheel 22, which facilitates the movement of the steel wire.

[0036] Both the wire feeding wheel 21 and the wire pressing wheel 22 have annular grooves 26 on their circumferential surfaces, which facilitates the movement of the wire along the annular grooves 26 when it passes through, thereby limiting and guiding the wire.

[0037] Preferably, the adjustment of the pressure roller 22 is achieved by setting a swing arm 25. One side of the swing arm 25 is fixedly connected to the movable shaft 24, and the other side is movably connected to the base plate 10 through the stepped bolt 51. When the swing arm 25 is rotated, one side of the swing arm 25 rotates around the stepped bolt 51, and the other side rotates together with the movable shaft 24, thereby causing the pressure roller 22 to deflect and adjusting the contact degree between the pressure roller 22 and the wire feeding roller 21. According to actual needs, the pressure on the steel wire is adjusted.

[0038] The adjustment hole 14 facilitates the movement of the movable shaft 24 along the adjustment hole 14, which is beneficial for adjusting the pressure roller 22.

[0039] It is worth mentioning that when the product leaves the factory, the fit between the pressure roller 22 and the feed roller 21 will be adjusted to keep the pressure of the feed roller 21 and the pressure roller 22 on the steel wire at an appropriate level. After long-term use, wear may occur between the feed roller 21 and the pressure roller 22. At this time, it is necessary to adjust the pressure roller 22 to fit closer to the feed roller 21 to ensure the pressure on the steel wire.

[0040] Preferably, a screw 52 is provided on one of the rocker arms 25 in each wire feeding assembly, and a hinge bolt 53 is provided on the other rocker arm 25. The screw 52 and the hinge bolt 53 are connected by a tension spring 56.

[0041] Furthermore, the aforementioned hinge bolt 53 is provided in two parts, and the two hinge bolts 53 are arranged perpendicular to each other.

[0042] In this embodiment, four rocker arms 25 are provided. Preferably, two rocker arms 25 in the same wire feeding assembly are grouped together. One of the rocker arms 25 in each group is fitted with a screw 52 and the other is fitted with a hinge bolt 53. The screw 52 and the hinge bolt 53 are connected by a tension spring 56.

[0043] The tension spring 56 can reset the pressure roller 22 after adjustment, ensuring that the pressure roller and the wire feeding roller are in close contact, which is beneficial to the movement of the steel wire. Here, the tension spring 56 is set between the two swing rods 25 in the same group to ensure that the pressure of the two pressure rollers 22 on the steel wire on the same wire feeding assembly remains stable.

[0044] It is worth mentioning that screws 52 are installed on the two adjacent swing arms 25 of the two wire feeding assemblies, and hinge bolts 53 are installed on the other two swing arms 25. The hinge bolts 53 facilitate installation and disassembly and make operation convenient.

[0045] Here, two hinge bolts 53 are set on each of the two swing arms 25. The two hinge bolts 53 are set perpendicular to each other, which can reduce the distance between the two swing arms 25, making it easier to install the tension spring 56 and ensuring that the tension spring 56 is in a suitable tension state, avoiding over-tension.

[0046] In addition, a handle 251 extends from the lever 25 near the front guide tube 31, which allows the operator to adjust the corresponding pressure roller 22 by moving the lever 25 according to the actual working conditions.

[0047] Preferably, the wire feeding conduit includes a front conduit 31, a rear conduit 333, and a plurality of intermediate conduits 32 located between the front conduit 31 and the rear conduit 333. One of the above-mentioned intermediate conduits 32 is provided between two adjacent wire feeding units 20, and each conduit is fixedly connected to the base plate 10 by a stud.

[0048] In this embodiment, the preferred wire feeding conduit is composed of multiple conduits. Each conduit is fixed to the base plate 10 by a stud, allowing the steel wire to pass through at a suitable distance from the base plate 10. The front conduit 31 and each intermediate conduit 32 are coaxially arranged. The rear conduit 333 is partially bent upward and fixed to the wire threading plate 16, which facilitates the entry of the steel wire into the wire threading plate 16.

[0049] Each intermediate guide tube 32 is spaced apart from each wire feeding unit 20, so that when the wire is positioned between two wire feeding units 20, each intermediate guide tube 32 provides guidance for the wire.

[0050] Furthermore, a detection bolt 54 is fixed between the intermediate conduit 32 and the rear conduit 333, and the top of the detection bolt 54 has a detection hole 55 for a steel wire to pass through.

[0051] To further ensure the smooth and accurate movement of the steel wire, a detection bolt 54 is installed between the intermediate guide tube 32 and the rear guide tube 333. When the steel wire actually moves, it passes through the detection hole 55 at the top of the detection bolt 54 without contacting the detection bolt 54. When the steel wire deviates or encounters an obstacle and bends, it touches the detection bolt 54, which will trigger an alarm. The host computer will then control the motor 13 to stop working, and the movement of the steel wire will stop.

[0052] In addition, if the steel wire breaks accidentally, the sensor will send a feedback to the host computer, which will then control the motor 13 to stop working.

[0053] This wire feeding plate uses a simple wire feeding mechanism with a reasonable structure and convenient operation. By setting multiple sets of wire feeding components, it is easy for the wire to move back and forth. At the same time, it can increase the friction when the wire retracts, which helps the wire to be recovered and ensures that the wire is smoothly returned to the designated position. The swing arm 25 is set to facilitate the adjustment of the distance between the pressure wheel 22 and the corresponding wire feeding wheel 21, which facilitates the smooth movement of the wire.

[0054] The embodiments described herein are merely preferred embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any modifications or additions to the specific embodiments described, or substitutions made by those skilled in the art, should be covered within the scope of protection of the present invention.
