Description

Technical Field

[0001] The utility model relates to the technical field of knitting machines, in particular to an adjusting device for a knitting machine. Background Art

[0002] A knitting machine is a process in which yarns of various raw materials and varieties are formed into coils using knitting needles and then connected into knitted fabrics through stringing. Knitted fabrics are soft in texture, have good wrinkle resistance and air permeability, and are widely used in life. During the knitting process, the distance between the two knitting tracks needs to be adjusted according to the knitting requirements, so an existing knitting machine adjustment device has been continuously innovated and developed. It can be seen that the current knitting machine adjustment device basically meets people's needs, but there are still some problems.

[0003] For example, the patent document with the announcement number CN213113732U discloses a double knitting track adjustment device for a knitting machine, which is provided with "a shell, which is provided with a accommodating groove; a spacing adjustment device, which includes a driving member, a transmission reversing member, a first screw rod, and a second screw rod; a first track fixing member, which is sleeved on the first screw rod and can move along the first screw rod; a second track fixing member, which is sleeved on the second screw rod and can move along the second screw rod. The double knitting track adjustment device for a knitting machine described in the utility model has a simple structure, and the driving handle is provided on the outer surface of the shell, which is convenient for people to move and adjust the distance between the knitting tracks, and by providing a rotating scale, it is convenient for people to grasp the adjustment accuracy. At the same time, since the first track fixing member and the second track fixing member move at the same time, the adjustment speed is faster than the prior art of only moving one of the knitting tracks."

[0004] However, when the above device is actually used, the first track fixing part and the second track fixing part are moved toward or away from each other by twisting the handle to achieve the purpose of adjusting the distance between the knitting tracks. Since the device needs to be adjusted manually, it is difficult to adjust the needle drop width by timely adjusting the distance between the double knitting tracks during knitting, resulting in poor knitting effect. In addition, in the process of knitting the fabric, fabrics of different thicknesses are often encountered, and the track height of the device is single, which leads to wrinkles and looseness on the surface of the processed fabric, thereby causing the problem of fabric waste. Therefore, a knitting machine adjustment device is urgently needed to solve the above problems. Utility Model Content

[0005] The utility model aims to provide a knitting machine adjustment device to solve the problem in the background art that, during use, the knitting demand is difficult to be met in time due to low adjustment efficiency, resulting in poor knitting effect.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solution, which discloses a knitting machine adjustment device, including a base, a connecting plate overlapped on the top of the base, and a servo motor is arranged inside the base;

[0007] A bidirectional lead screw, the top end of which is connected to the output end of the servo motor, and the bottom end of which is rotatably connected to the inner wall of the base, moving blocks are threadedly connected to both sides of the outer surface of the bidirectional lead screw, and the top of the moving block is fixedly connected to the bottom of the connecting plate, a guide frame is fixedly installed on the top of the connecting plate, an extension plate is connected to the inner wall of the guide frame, a connecting frame is fixedly installed on the top of the extension plate, and a bracket is provided on one side of the connecting frame.

[0008] Preferably, a fixing plate is fixedly mounted on the inner side wall of the base, and the outer surface of the fixing plate is connected through the inner wall of the connecting plate.

[0011] Preferably, a scale is provided on the outer surface of the fixing plate, and the fixing plate is located above the bidirectional lead screw.

[0012] Preferably, one side of the extension plate is provided with side-by-side clamping grooves, one side of the guide frame is threadedly connected with a fastening bolt, and the fastening bolt is matched with the clamping groove.

[0013] Preferably, a connecting hole is provided on one side of the connecting frame, and the connecting hole is adapted to the connecting bolt.

[0014] Preferably, a protrusion is provided on the outer surface of the extension plate, and the protrusion is slidably connected to the inner wall of the guide frame.

[0015] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0016] 1. The utility model turns on the servo motor to make the two tracks move towards or relative to each other, so as to adjust the horizontal distance between the two tracks, so as to achieve the effect of quickly moving and adjusting the tracks. By taking out the fastening bolts from the clamping grooves, the bracket is driven to move up and down, thereby driving the connecting frame to move up and down. At this time, the track moves up and down with the connecting frame through the connecting frame, so as to fine-tune the direction of the track to adjust the tightness of the textile rope, ensure the knitting effect, and make the quality of the finished product better. The equipment is not only convenient for adjusting the knitting track, but also convenient for adjusting the tightness of the textile rope by adjusting the height of the track, which is beneficial to the later knitting processing operation.

[0017] 2. The utility model uses two connecting plates to move toward or relative to the two tracks along the outer surface of the fixed plate, and the scale is scaled from the center of the fixed plate to both sides, so that the distance between the two tracks can be determined by reading the size of one side and then doubling it. The device is easy to read, so that the distance between the two tracks can be quickly determined, which is conducive to precise adjustment of the tracks, making the knitting processing operation better.

[0027] When adjusting the knitting track 12, the servo motor 3 is turned on, and then the output end of the servo motor 3 drives the bidirectional screw 4 to rotate, and then the bidirectional screw 4 drives the moving block 5 to rotate, and then the moving block 5 is subjected to the resistance of the base 1, so that the two moving blocks 5 move toward or relative to each other along the outer surface of the bidirectional screw 4, and then the two moving blocks 5 drive the two guide frames 6 to move toward or relative to each other through the connecting plate 2, and then the two guide frames 6 drive the two connecting frames 8 to move toward or relative to each other through the extension plate 7, and then the two connecting frames 8 drive the two tracks 12 to move toward or relative to each other through the connecting frame 11, so as to achieve the purpose of adjusting the distance between the two tracks 12, by rotating the fastening bolt 16 to keep it away from the clamping groove 15, and then the staff puts his hand through the bracket 9 and applies an upward or downward force to it, and then the bracket 9 drives the extension plate 7 to move upward or downward along the inner wall of the guide frame 6 through the connecting frame 8, so that the extension plate 7 extends or retracts, and at the same time, the track 12 moves upward or downward along the connecting frame 8 through the connecting frame 11, so as to achieve the purpose of adjusting the height of the track 12.

[0028] Furthermore, a side of the extension plate 7 is provided with a clamping groove 15 arranged side by side, a side of the guide frame 6 is threadedly connected with a fastening bolt 16, and the fastening bolt 16 is adapted to the clamping groove 15, and a protrusion is provided on the outer surface of the extension plate 7, and the protrusion is slidably connected to the inner wall of the guide frame 6;

[0029] By inserting the fastening bolts 16 into the clamping grooves 15, the extension plate 7 is fixedly connected to the guide frame 6. The design of the protrusions on the extension plate 7 enables the extension plate 7 to move up and down along the inner wall of the guide frame 6 only when subjected to vertical upward or downward force, thereby ensuring the stability of the extension plate 7 and further ensuring the stability of the track 12, thereby improving the quality of the finished product.
