Abstract
Description
Technical Field
[0001] This utility model relates to the field of needle plate technology for computerized flat knitting machines, and specifically to a needle plate correction device for computerized flat knitting machines. Background Technology
[0002] A computerized flat knitting machine is a double-needle plate weft knitting machine. Its cam mechanism is like a set of planar cams. The needle feet can enter the grooves of the cams. Moving the cams forces the needles to make regular up-and-down movements within the needle grooves of the needle plate. Through the action of the needle hook and the needle tongue, the yarn can be knitted into fabric. The needle plate is one of the key components in the knitting process, mainly playing a role in bearing and guiding. The needle plate has multiple grooves through which the needles move up and down to achieve the knitting of the fabric. The needle plate, in cooperation with other components, ensures that the needles move accurately in the correct position, thereby controlling the density, structure and pattern of the fabric. At the same time, the needle plate also plays a role in stabilizing the needles, ensuring that the needles do not deviate or jam during the knitting process, and guaranteeing the stability and precision of fabric production.
[0003] A search revealed Chinese patent "A Correction Device for a Needle Plate of a Computerized Flat Knitting Machine" (authorization announcement number CN214053171U). This utility model discloses a correction device for a needle plate of a computerized flat knitting machine, comprising a frame, a pair of first pressing devices, a transverse moving device, and a second pressing device. The pair of first pressing devices are symmetrically arranged at both ends of the bottom of the frame. The transverse moving device is installed on the upper part of the frame. The second pressing device is connected below the transverse moving device. The first pressing device includes a first connecting member that can move up and down, and a rubber pad is provided below the first connecting member. The transverse moving device includes a slide that can move horizontally. A lead screw is threadedly connected to the inside of the slide through a nut. The lead screw is rotatably installed on both side walls of the frame. The second pressing device is connected below the slide and includes a roller frame that can move up and down. A pressure roller is provided inside the roller frame. This utility model is not only convenient to use but also provides accurate correction.
[0004] Although the above-mentioned computer flat knitting machine needle plate correction device can flatten the needle plate using pressure rollers, the grooves on the surface of the needle plate will also be deformed when it was originally bent. The above-mentioned device can only flatten the shape of the needle plate. After pressing, the grooves of the needle plate still have the bending or deformation caused by the original bending. Therefore, there is a problem of incomplete correction.
[0005] Based on this, this utility model designs a needle plate correction device for a computerized flat knitting machine to solve the above problems. Utility Model Content
[0006] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a needle plate correction device for a computerized flat knitting machine.

[0008] A needle plate correction device for a computerized flat knitting machine includes: a housing and a driving component disposed inside and above it;
[0009] A calibration component is disposed at the moving end of the drive component and is used to level and calibrate the needle plate.
[0010] The correction component includes a pressure roller that moves along the lower end of the drive unit via a rotating shaft. The pressure roller is hollow and has multiple perforations arranged in a ring array on its surface. The pressure roller contains a number of recovery strips equal to the number of perforations.
[0011] Furthermore, both ends of one side of the recovery strip are fixedly connected to extrusion blocks, which are rectangular in shape and the inclined portions of the two extrusion blocks are arranged opposite each other.
[0012] Furthermore, an electric push rod is provided in the pressure roller, and extrusion blocks are fixedly connected to both ends of the electric push rod;
[0013] Furthermore, the extrusion block is tapered, and the tapered portion of the extrusion block is adapted to the inclined portion of the extrusion block.

Beneficial effects
[0018] By setting a recovery strip in the pressure roller, the needle plate groove that still has deformation can be squeezed after the needle plate is pressed by the pressure roller, so that the needle plate groove can be restored, improving the dimensional accuracy of the groove, avoiding needle jamming or unnecessary friction due to irregular shape, and also saving the time and process of subsequent personnel to re-adjust the groove.
[0019] By setting up a correction component, when the needle plate needs to be leveled, the drive component can drive the pressure roller to press the bent or curved parts of the needle plate, improving the overall flatness of the needle plate and also facilitating the smooth operation of the internal needles.

[0027] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.
[0028] The present invention will be further described below with reference to the embodiments.
[0029] In some embodiments, please refer to the appendix to the instruction manual. Figure 1-4 A needle plate correction device for a computerized flat knitting machine includes a housing 1 and a drive component 2 disposed inside and above it; a correction component 6, which is disposed at the moving end of the drive component 2 and is used to level and correct the needle plate.
[0030] In some embodiments, such as Figure 1-4 As shown, in a preferred embodiment of this utility model, the correction component 6 includes a pressure roller 601 that moves below the driving component 2 via a rotating shaft. The pressure roller 601 is hollow and has multiple perforations arranged in a circular array on its surface. The pressure roller 601 contains a number of recovery strips 605 equal to the number of perforations. When the operator needs to level and correct the needle plate, the needle plate is first placed at the bottom of the housing 1, ensuring its position corresponds to the pressure roller 601. Then, two cylinders 4 simultaneously drive two pressure plates 5 downwards to press the two ends of the needle plate and position it. At this point, the driving component 2 opens and drives the pressure roller 601 downwards until its lower end contacts the needle plate. The driving component 2 then drives the pressure roller 601 to move from left to right, rolling it across the surface of the needle plate during this movement. The device can press the bent parts of the needle plate. When the pressure roller 601 moves to the rightmost end, the controller 3 controls the electric push rod 602 to open. At this time, the two electric push rods 602 simultaneously drive the two extrusion blocks 604 to move to opposite sides. When the extrusion block 604 is displaced, it immediately contacts the extrusion block 606 of the recovery strip 605. At this time, through the inclined extrusion block 604 and the extrusion block 606, multiple recovery strips 605 extend outward at the same time. Then, the drive unit 2 can drive the pressure roller 601 to move in the opposite direction. When the pressure roller 601 moves in the opposite direction, the recovery strips 605 extending from the pressure roller 601 enter the groove of the needle plate in an orderly manner to press the groove of the needle plate, so that the bent or irregular groove can be straightened in time, and at the same time, it also plays a role in overall correction.
[0031] In this embodiment of the invention, compression blocks 606 are fixedly connected to both ends of one side of the recovery strip 605. The compression blocks 606 are rectangular in shape, and the inclined portions of the two compression blocks 606 are arranged opposite to each other. Through the compression blocks 606, the recovery strip 605 can be extended outward in conjunction with the extrusion block 604, thereby achieving the effect of straightening the needle plate groove.
[0032] In this embodiment of the utility model, an electric push rod 602 is provided in the pressure roller 601, and extrusion blocks 604 are fixedly connected to both ends of the electric push rod 602. First, the controller 3 controls the electric push rod 602 to open. At this time, the two electric push rods 602 simultaneously drive the two extrusion blocks 604 to move to opposite sides. When the extrusion block 604 is displaced, it contacts the extrusion block 606 of the recovery strip 605 at the first moment. At this time, after being squeezed by the inclined surfaces of the extrusion block 604 and the extrusion block 606, multiple recovery strips 605 extend outward simultaneously.
[0033] In this embodiment of the utility model, the extrusion block 604 is cone-shaped, and the cone-shaped part of the extrusion block 604 is adapted to the inclined part of the extrusion block 606;
[0034] In this embodiment of the invention, a positioning ring 603 is sleeved on the surface of the electric push rod 602, and one end of the positioning ring 603 near the inner wall of the pressure roller 601 is fixedly connected to the inner wall of the pressure roller 601; the positioning ring 603 can fix the electric push rod 602 without affecting the movement of the recovery strip 605.
[0035] In this embodiment of the utility model, the material of the recovery strip 605 is iron, and a tapered strip 607 is provided on one side of the recovery strip 605; through the tapered strip 607, the recovery strip 605 can enter the groove of the needle plate to squeeze and straighten the bent groove.
[0036] In this embodiment of the utility model, the length and width of the recovery strip 605 are adapted to the size of the perforation of the pressure roller 601; through the above description, it is possible to prevent the angle of the recovery strip 605 from shifting after being pressed.
[0037] In this embodiment of the utility model, a controller 3 is provided on one side of the housing 1. The controller 3 is electrically connected to the driving end of the driving component 2, and the controller 3 is signal connected to the electric push rod 602. Cylinders 4 are fixedly connected to both inner sides of the housing 1, and pressure plates 5 are fixedly connected to the telescopic ends of the cylinders 4.
[0038] It should be noted that the drive component 2 consists of a motor, a lead screw, a threaded sleeve, a slide bar, and a push rod. The motor and the push rod are both controlled by the controller 3. The motor is fixed to the outside of the housing 1, and its output end passes through the housing 1 and is fixedly connected to the lead screw. The lead screw is located at the inner top of the housing 1, and one end of it is fixedly connected to the inner wall of the housing 1 through a bearing seat. The threaded sleeve is threadedly connected to the surface of the lead screw. The slide bar is located above the lead screw, and the threaded sleeve slides on the surface of the slide bar. The push rod is fixed below the threaded sleeve, and the telescopic end of the push rod is fixedly connected to the rotating shaft shell of the pressure roller 601.
[0039] When the height and position of the pressure roller 601 need to be adjusted, the controller 3 is first turned on. The controller 3 is electrically connected to the motor of the drive component 2. When the pressure roller 601 needs to be moved left or right, it is only necessary to control the motor to rotate in reverse or forward. At this time, the lead screw can drive the threaded sleeve to move laterally along the lead screw. When the height of the pressure roller 601 needs to be adjusted, it is only necessary to control the extension and retraction of the push rod, which can control the up and down movement of the pressure roller 601. At the same time, after the operator places the needle plate on the inner bottom platform of the box 1, the controller 3 can control the cylinder 4 to drive the pressure plate 5 to move downward, so as to press and limit the two sides of the needle plate. When the pressure roller 601 needs to trim the groove of the needle plate, the controller 3 controls the electric push rod 602 to open through the signal, which can make the electric push rod 602 simultaneously move the two extrusion blocks 604 to opposite sides and extrude the recovery strip 605.
[0040] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
