Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

In which like parts are designated by like reference numerals. It should be noted that the terms "front," "back," "left," "right," "upper" and "lower" used in the following description refer to directions in the drawings, and the terms "bottom" and "top," "inner" and "outer" refer to directions toward and away from, respectively, the geometric center of a particular component.

Example (b): the utility model provides a tight integral type of clamp of rectifying is received and is unreeled structure, combines fig. 1 and fig. 2 to show, includes base 1, installs slide rail 11 on the base 1, and slide rail 11 arranges along base 1 length direction, and slide rail 11 is provided with four and distributes in the corner position of base 1, has left cursor slide 3 and right cursor slide 5 through slide rail 11 sliding connection on the base 1. A first chuck 31 is arranged on the right side surface of the left sliding arm 3, a second chuck 51 is arranged on the left side surface of the right sliding arm 5, and the left end and the right end of the paper tube are clamped through the first chuck 31 and the second chuck 51 during operation.

Referring to fig. 1 and 2, a ball screw 2 is mounted on a base 1, the ball screw 2 is also arranged along the length direction of the base 1, a left slide arm 3 is in threaded connection with the ball screw 2, and the ball screw 2 rotates to drive the left slide arm 3 to slide left and right. One end of the ball screw 2 is provided with a servo motor 21, the servo motor 21 is fixed on the base 1, and the servo motor 21 provides power required by the rotation of the ball screw 2. A bearing seat 22 is arranged at the connecting position of the ball screw 2 and the servo motor 21.

Referring to fig. 1 and 3, a support 23 is disposed at an end of the ball screw 2 away from the servo motor 21, the support 23 is fixed on the base 1, a spacer 25 is disposed on the support 23, the spacer 25 is sleeved on the end of the ball screw 2, a bearing is mounted on an inner side of the spacer 25, and the spacer 25 is in contact with the ball screw 2 through the bearing.
