Description

 The present invention relates to a circular knitting machine coil slack adjusting device, and particularly to a knock loose cam coil slack adjusting device of a cam box.

 The circular knitting machine adjusts the position of knockover cam to control the degree of coil density slack on the woven fabric, and installs multiple knockover cams on the circular knitting machine to adjust the coil density for different positions of the woven fabric. Make adjustments. A device that adjusts the position of only a single knockover cam among the know-how, and rotates the belt slide as in the patent proposals of the Chinese and Taiwanese utility models No. M251848 and No. M247597 of the applicant. Adjust the knockover cam position by adjusting. However, methods such as knockover cam adjustment require manual adjustment, and when the knockover cam adjustment quantity is large, considerable manpower and time are consumed, and an error occurs depending on the person. In order to solve this problem, as shown in US Pat. No. 5,511,392, the vertical position of the tray (mounting plate) is adjusted using an elevating means and installed on the tray (knock over cam). Raise or lower the cam box having This design can simultaneously adjust multiple knockover cam vertical positions, but does not allow fine adjustment of coil density for individual fabric ranges.

 In addition, as in the conventional US Pat. No. 7065988, a device for changing coil density of a circular knitting machine, having a movement adjuster connected to a slide, the slider being a cam of the knitting machine The cam box slides and supports a knockover cam. The movement adjuster includes an actuator, which is connected to an adjustment cam, and the cam adjustment rotates the shaft that surrounds the cam adjustment to rotate to a predetermined angle. The cam adjustment consists of a single external active profile and two cam followers, the two cam followers are arranged on the slide, and the cam adjustment is applied to the actuator. When receiving the drive, the two cam followers are linked to adjust the position of the knock over cam installed on the slide. The above design adjusts the position of a single knockover cam, and it is not necessary to adjust the position of the knockover cam by moving it up or down by the tray of the knitting machine. Inaccuracies and cumbersome operating processes can be avoided. The cam adjustment is an eccentric cam, and the contact position of the two cam followers requires precise calculation and processing when manufacturing, the knock over cam makes accurate transitions, and the cam adjustment is performed on the cam box. Since it is deeply fitted, the size and range of movement are limited, making it more difficult for industrial production.

 The main object of the present invention is to adjust the position of a single knockover cam to further simplify the structure and facilitate application in industrial manufacture or assembly. To achieve the above object, a circular knitting machine coil slack adjusting device provided with the present invention is installed on a circular knitting machine, and the circular knitting machine includes at least a knitting needle for drawing a knitting line.

The design of the above-mentioned interlocking mechanism and the relative opinion combination on the slide makes it possible to accurately adjust the position of the knockover cam.

 Another object of the present invention is to avoid errors resulting from manual knockover cam position adjustment and to maintain or adjust the position of the knockover cam at any time in the operation of the circular knitting machine. In order to achieve the above-described object, the present invention further provides a detection device that is installed on the drive device and detects the drive state of the drive device, and the detection device inputs a detection signal and a processing unit to the drive state of the drive device. The processing unit returns an adjustment signal to the driving device by a detection signal and adjusts the driving state of the driving device, so that the driving signal of the driving device is a rotational speed, and the processing unit is previously set to the knock over cam position. In addition, a standard signal output for outputting the adjustment signal after comparison with the detection signal is set. This allows the knockover cam to be positioned at a predetermined position by the standard signal set during operation of the circular knitting machine, or the degree of coil loosening of the woven fabric is changed by adjusting the position of the knockover cam in the cloth weaving process. It is possible to weave various patterns.
