Description

Technical Field

[0001] The utility model relates to a split-type large tripod structure for a knitting machine, and belongs to the technical field of large tripods for knitting machines. Background Art

[0002] The large tripod frame of the circular knitting machine is used to install the upper needle cylinder and its transmission mechanism, etc. The size is very large. The size of the commonly used large tripod frame is between 10-70 inches. It is all made of one-piece casting. The main transmission shaft is driven by the motor to rotate. The main transmission shaft then drives the large tripod gear to rotate through the driving mechanism installed on it. The large tripod gear is coaxially fixedly installed with the barrel core shaft, and the barrel core shaft and the bead plate are coaxially fixedly installed. The upper needle plate is fixedly installed on the edge of the bead plate, so the upper needle plate can be driven to rotate after the motor is started;

[0025] Example 1 Please refer to Figure 1-Figure 6 , the utility model provides a technical solution:

[0026] A split-type tripod structure for a knitting machine comprises a tripod frame 1 for a knitting machine, wherein a bottom plate 2 is fixedly connected to the side surface of the tripod frame 1 near the bottom thereof, a fixing frame 3 is fixedly connected to the front side of the bottom plate 2, a driving motor 4 is fixedly installed at the bottom of the inner wall of the fixing frame 3, a threaded rod 5 is fixedly connected to the output end of the driving motor 4, a threaded sleeve 6 is threadedly connected to the surface of the threaded rod 5, a limiting assembly is connected to the bottom of the threaded sleeve 6, a lifting plate 7 is fixedly connected to the top of the threaded sleeve 6, a jacket plate 8 is fixedly connected to the top of the lifting plate 7, an annular dust cover 9 is fixedly connected between the bottom of the jacket plate 8 and the top of the bottom plate 2, a card slot 10 is opened on the jacket plate 8 near the top of its inner wall, an upper sealing plate 11 is clamped on the inner wall of the card slot 10, and a firm screw 12 is threadedly connected to the interior of the upper sealing plate 11 and the interior of the jacket plate 8 through an internal thread groove.

[0027] Specifically, Figure 1-Figure 6 As shown, the limiting assembly includes a limiting plate 13 and a limiting groove 14, wherein the limiting plate 13 is fixedly connected to the bottom of the threaded sleeve 6, and the limiting groove 14 is provided on the side of the inner wall of the fixed frame 3, and the inner wall of the limiting groove 14 is slidably connected to the surface of the limiting plate 13. By setting the limiting plate 13 and the limiting groove 14, the movement trajectory of the threaded sleeve 6 is limited, so that the rotation of the threaded rod 5 can drive the threaded sleeve 6 to move up and down.

[0028] Specifically, Figure 1-Figure 6As shown, a spring telescopic rod 19 is fixedly installed on the side of the bottom plate 2 near its inner wall, and the top of the spring telescopic rod 19 is fixedly connected to the bottom of the outer plate 8. The number of the spring telescopic rods 19 is at least three, and the at least three spring telescopic rods 19 are evenly distributed on the left and right rear sides of the knitting machine frame 1. The addition of the spring telescopic rod 19 can ensure the circumferential and smooth movement of the outer plate 8. The bottom of the upper sealing plate 11 is fixedly connected to a soft pad 20, and the component material of the soft pad 20 is butadiene rubber. Because the lower surface of the upper sealing plate 11 is fixedly connected to the soft pad 20, the wear of the top of the knitting machine frame 1 caused by the accidental fall of the upper sealing plate 11 can be avoided.

[0029] Example 2 Please refer to Figure 1-Figure 6 The difference between this embodiment and the embodiment 1 is that: the bottom of the lifting plate 7 is fixedly connected with a positioning card plate 15, and the top of the fixed frame 3 near its inner wall is fixedly connected with a positioning card slot plate 16, and the inner wall of the positioning card slot plate 16 and the surface of the positioning card plate 15 are snapped and adapted. By setting the positioning card plate 15 and the positioning card slot plate 16, the lifting plate 7 can be stored in the interior of the fixed frame 3 in the normal state. The side of the bottom plate 2 is fixedly connected with a placement slot plate 17, and the side of the inner wall of the placement slot plate 17 is fixedly installed with an electromagnetic suction plate 18. After releasing the magnetic suction control of the electromagnetic suction plate 18 from the placement slot plate 17, the upper sealing plate 11 can be taken out from the interior of the placement slot plate 17.

[0030] Working principle of the utility model: when in use, under normal use, the top of the knitting machine frame 1 can be maintained above the outer plate 8, so as to carry out the operation of the split large tripod structure of the knitting machine and the textile wire pulling work, and when the knitting machine frame 1 is temporarily placed in a non-use state, the drive motor 4 can be started to drive the threaded rod 5 to rotate, and the movement trajectory of the threaded sleeve 6 is limited by the setting of the limit plate 13 and the limit groove 14, so that the rotation of the threaded rod 5 can drive the threaded sleeve 6 to move up and down, and the threaded sleeve 6 can drive the outer plate 8 to adjust the height, and the addition of the spring telescopic rod 19 can ensure the circumferential and stable movement of the outer plate 8, and then the annular dust cover 9 is pulled and sleeved on the knitting machine frame 1 The outer part of the upper cover 11 is connected to the outer cover 8 by the clamping relationship of the clamping groove 10, and the upper cover 11 is locked at the outer cover 8 by the firm screw 12. Because the lower surface of the upper cover 11 is fixedly connected with the soft pad 20, the wear of the top of the knitting machine frame 1 caused by accidental falling of the upper cover 11 can be avoided, thereby ensuring the external protection and dustproof effect of the knitting machine frame 1.

[0031] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
