Description

[Detailed Description of the Invention] The present invention relates to a pressing device for pressing a top roller in a spinning machine.

Conventionally, as shown in FIGS. 3 and 4, the pressing device presses an end bush 10, in which bearing devices such as needle bearings are fitted to both ends of a top roller 14, using a spring or hydraulic pressure, and the sliver is cut into 12 pieces. , top roller 1
4 or the bottom roller 15, or by replacing the bearing device, etc., there are many operations for pressing or releasing the pressing. In addition, since the top roller 14 has a surface covered with rubber, it must be replaced periodically due to wear or re-polishing of the rubber.

Since the working position of the drafting roller section 13 in a lap forming machine, blending drawing machine, etc. is mostly in the lateral direction with respect to the flow of the sliver 12, the pressing device with the mechanism as shown in Figs. 3 and 4 does not work. In the operation of pressing and releasing the pressing, it is difficult to operate the lever 16 located on the opposite side of the working side 4.

For example, in FIG. 4, the pressing arm 17 is
To rotate in eight directions, move lever 16 in the direction of arrow 19.
When the shaft 20 is rotated in this direction, the shaft 20 is rotated about the shaft 21, and it is necessary to remove the hook 22 from the pin 23. Therefore, the levers 16 and 16' are operated to press or release the pressure, but it is obvious that the lever 16 is particularly difficult to operate because the sliver 12 is in front of it.

In order to facilitate the operation from the lateral direction, as shown in FIGS. 5 and 6, the front and rear of the pressurizing arm 1 are fixed with a connecting rod 2, and a support shaft 5 is provided on the opposite side of the connecting rod 2 from the working side 4. , a pressing device may be considered in which a pin 8 is provided so that the hook 7 can be hung on the working side 4, but the pressing rod 24 on the shaft 5 side, which becomes the fulcrum when pressing, is attached to the shaft 5.
Press the end button 25 on the side before the end button 26 on the opposite side to the shaft 5,
6 floats up and comes off the guide (not shown) for guiding the end bush 26, making the pressing operation difficult.

Therefore, a device was proposed in which the pressure from a spring was changed to hydraulic pressure. However, the device is expensive and
Since the press uses oil, there is a lot of fluff adhesion due to oil stains, and there is also the disadvantage that the press force changes due to the heat generated by the operation of the machine.

The present invention was devised in view of the above-mentioned drawbacks, and the following embodiments will be explained with reference to the drawings. 1 pair of left and right pressing arms 1
Connecting rods 2 are provided at the front and rear of the connecting rod 2, and approximately the center of the connecting rods 2 is set as a shaft 3, and the pressing arm 1 is installed so as to be rotatable in an arcuate direction. Further, a pressing rod 6 having a support shaft 5 in the direction opposite to the working side 4 is installed on the outside of each of the pair of front and rear connecting rods 2. A pin 8 for hooking a hook 7 is provided on the working side 4 of the pressing rod 6, and by operating a lever 11, the top roller can be pressed or released.

When pressing, a pair of front and rear pressing rods 6 are rotated in the direction of arrow 9. The left and right pressing arms 1 press the end bushing 10 as the pressing rod 6 moves in the direction of the arrow 9, but even if one of the pressing arms presses first, the left and right pressing arms 1 will rotate around the shaft 3 and move from side to side. The effect is to maintain the balance of the pressing force.

Since the lever 11 rotates from the working side 4 in a direction transverse to the flow of the sliver 12, the pressing operation is easy, and since the parts that engage with the pressing device etc. move upward, the sliver 12 is moved to the drafting roller section 13.
This makes the work of supplying water extremely easy.
