Description

Technical Field

[0001] This utility model relates to the field of flat knitting machines, and in particular to a gauge control device for flat knitting machines. Background Technology

[0002] In a flat knitting machine, the gauge determines how much yarn the needle takes in. The larger the gauge, the more yarn is taken in, and the looser the loops. The function of the gauge is to control how much the needle descends in the needle groove, which determines the amount of yarn taken in. Generally, the depth of the gauge is determined by a rotating shaft structure controlled by a stepper motor to achieve the needle pressing depth. The deeper the gauge triangle is pressed, the more yarn is taken in, and the larger the gauge is.

[0003] When applying for this utility model, the applicant found through a search that a Chinese patent disclosed "a knitting machine gauge control device" with application number "CN200620001589.8". This patent mainly uses a motor to drive a turbine disk to rotate in order to adjust the position of the gauge drive block. However, the turbine disk has high requirements for the rotational accuracy of the motor shaft when adjusting the position, which leads to high requirements for motor control. When the rotational accuracy of the motor shaft is insufficient, the needle pressing depth will not reach the expected effect, which is not conducive to the weaving of the fabric. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a gauge control device for a flat knitting machine.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a gauge control device for a flat knitting machine, comprising a panel, a moving groove formed on the surface of the panel, a limiting plate fixedly connected to the back of the panel, a motor fixedly connected to the back of the limiting plate, a lead screw fixedly connected to the output end of the motor, and the end of the lead screw away from the motor being movably connected to the back of the panel, a moving block mounted on the surface of the lead screw, the moving block being located inside the limiting plate, and the cross-sectional structure of the moving block being a right trapezoidal structure, a connecting block movably connected inside the moving groove, the connecting block being located above the moving block, a gauge drive block fixedly connected to one end of the connecting block, and the gauge drive block being located on the front of the panel.

[0006] As a further description of the above technical solution:

[0007] The limiting plate has a "U" shaped structure, and the position of the limiting plate corresponds to the position of the moving groove.

[0008] As a further description of the above technical solution:

[0009] The movable block has a first threaded hole inside, and the lead screw is located inside the first threaded hole. The inner wall of the first threaded hole is threadedly connected to the surface of the lead screw.

[0010] As a further description of the above technical solution:

[0011] The connecting block has a second threaded hole inside, and a threaded rod is threadedly connected inside the second threaded hole.

[0012] As a further description of the above technical solution:

[0013] The bottom of the threaded rod is movably connected to a base plate, which is located below the connecting block.

[0014] As a further description of the above technical solution:

[0015] A handle is fixedly connected to the top of the threaded rod, and the handle is located above the connecting block.

[0016] This utility model has the following beneficial effects:

[0017] 1. Compared with the prior art, this knitting flat knitting machine's gauge control device, through a motor, lead screw, moving block, connecting block, and gauge drive block, uses a motor to drive the lead screw to rotate, which in turn drives the moving block to move back and forth on the lead screw. When the moving block moves back and forth on the lead screw, it also moves the connecting block up and down, thereby controlling the up and down movement of the gauge drive block. Compared with the existing knitting machine gauge control devices that use a motor to drive a turbine disk to rotate in order to adjust the position of the gauge drive block, but the turbine disk has high requirements for the rotational accuracy of the motor shaft when adjusting the position, this knitting flat knitting machine's gauge control device can use a servo motor to control the number of rotations of the motor shaft to change the position of the moving block, thereby adjusting the height of the gauge drive block, which facilitates the gauge control of the knitting flat knitting machine.

[0018] 2. Compared with the prior art, the gauge control device of this flat knitting machine, through the connecting block, threaded rod and base plate, can control the up and down movement of the base plate by rotating the threaded rod during use, and can change the distance between the connecting block and the base plate, so that the height of the gauge drive block can be better adjusted when the motor is working, which facilitates the gauge control of the flat knitting machine.

[0026] Reference Figure 1-5 This utility model provides a gauge control device for a flat knitting machine: It includes a panel 1, with two inclined moving grooves 2 on the surface of the panel 1. Two limit plates 3 are fixedly connected to the back of the panel 1, each with a U-shaped structure. The positions of the two limit plates 3 correspond to the positions of the two moving grooves 2. A motor 4 (servo motor or stepper motor) is fixedly connected to the back of each limit plate 3. A lead screw 5 is fixedly connected to the output end of the motor 4, with the end of the lead screw 5 furthest from the motor 4 movably connected to the back of the panel 1. A moving block 6 is mounted on the surface of the lead screw 5, and a first threaded hole 7 is formed inside the moving block 6. The lead screw 5 is located inside the first threaded hole 7. The inner wall is threadedly connected to the surface of the lead screw 5. The moving block 6 is located inside the limiting plate 3. Under the action of the motor, the moving block 6 can move back and forth inside the limiting plate 3. The cross-sectional structure of the moving block 6 is a right trapezoidal structure. The moving groove 2 is movably connected to the connecting block 8, which is located above the moving block 6. When the moving block 6 moves, it can control the moving block 8 to move up and down. One end of the connecting block 8 is fixedly connected to the mesh drive block 9. When the connecting block 8 moves, it can move the mesh drive block 9 up and down. The mesh drive block 9 is located on the front of the panel 1. When in use, the mesh drive block 9 is connected to the needle. The amount of needle descent in the needle groove is controlled by the mesh drive block 9, which determines the amount of yarn taken by the knitting machine. The deeper the mesh drive block 9 presses, the more yarn is taken and the larger the mesh size.

[0027] The connecting block 8 has a second threaded hole 10 inside, and a threaded rod 11 is threadedly connected inside the second threaded hole 10. The bottom of the threaded rod 11 is movably connected to a base plate 12, which is located below the connecting block 8. A handle 13 is fixedly connected to the top of the threaded rod 11, which is located above the connecting block 8. When in use, the screw 11 can be rotated to control the bottom plate 12 to move up and down, which can change the distance between the connecting block 8 and the bottom plate 12. This allows the motor 4 to better adjust the height of the gauge drive block 9 when it is working, which is convenient for gauge control of the flat knitting machine.

[0028] Working principle: When in use, the motor 4 drives the lead screw 5 to rotate, which in turn drives the moving block 6 to move back and forth on the lead screw 5. When the moving block 6 moves back and forth on the lead screw 5, it will move the connecting block 8 up and down, thereby controlling the size drive block 9 to move up and down. When using the size control device of this flat knitting machine, the number of rotations of the motor shaft of the motor 4 can be controlled by a servo motor to change the position of the moving block, thereby adjusting the height of the size drive block 9, which facilitates the size control of the flat knitting machine.

Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
