Detailed Description

Embodiments of the present utility model are described in detail below, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to like or similar elements or elements having like or similar functions throughout. The embodiments described below by referring to the drawings are illustrative and intended to explain the present utility model and should not be construed as limiting the utility model.

The utility model relates to a non-roundness adjusting device of a cable protection tube extrusion production line, which comprises a base 100, a sliding seat 300, a pressing wheel 400 and a screw 500.

As shown in fig. 1, the base 100 has a rectangular frame shape as a whole. Two guide rods 200 are provided on the base 100. The guide bar 200 is a smooth round bar. The two guide rods 200 are vertically distributed, and the axial direction of the guide rods 200 is horizontally oriented left and right. Two sliders 300 are slidably mounted on the base 100 in a left-right direction. The upper and lower parts of the sliding base 300 are respectively connected with the two guide rods 200 in a sliding manner. The two carriages 300 horizontally move along the guide bar 200. Each carriage 300 has a pinch roller 400 mounted thereon. Pinch roller 400 is 8 font, and the pinch roller is wide along axial both ends, and the middle part is towards the axis sunken, and the axial of pinch roller 400 is vertical orientation. Wherein puck 400 is axially adjustable on carriage 300. Two screws 500 are screwed to the left and right sides of the base 100, respectively. The screw 500 is horizontal and transverse. After the screw 500 passes through the base 100, one end of the screw 500 is connected to the slider 300. In actual use, the base 100 is mounted at the pipe outlet of an extrusion apparatus. The relative distance between the two pinch rollers 400 is adjusted according to the diameter of the cable protection tube, and the sliding seat 300 and the pinch rollers 400 at the two sides are driven to move relatively by rotating the screw rods 500 at the two sides. In the extrusion molding process of the cable protection pipe, the cable protection pipe is output from the pipeline outlet along the axial direction, and the pinch rollers 400 on two sides squeeze the two sides of the cable protection pipe along the radial direction in a centering way, so that the ellipse of the cable protection pipe is adjusted to be round. According to the actual roundness adjustment condition, the pinch roller 400 is finely adjusted relative to the sliding seat 300, so that the forming roundness of the cable protection tube is ensured. Whether the two screws 500 are coaxial or not does not affect the relative position of the two puck 400.

In some embodiments of the present utility model, for facilitating rotation of the screw 500, a turntable 510 is provided on the end of the screw 500 remote from the carriage 300. The operator rotates the screw 500 by rotating the dial 510.

In some embodiments of the present utility model, two fixing bases 310 are disposed on the sliding base 300. The pinch roller 400 is located between the fixing bases 310, and two axial ends of the pinch roller 400 are respectively rotatably installed on the fixing bases 310 through rotating shafts. Wherein, an adjusting knob 320 is provided on the fixing base 310, and the adjusting knob 320 and the fixing base 310 can be connected by screw threads. The adjusting knob 320 is abutted on the end of the rotating shaft, and the axial position of the pinch roller 400 relative to the fixed seat 310 is adjusted through the adjusting knob 320, so that the position of the pinch roller 400 is finely adjusted.

In some embodiments of the present utility model, a spring 110 is disposed between the slider 300 and the base 100, and the spring 110 has an elastic force on the slider 300. The spring 110 elastically pulls the slider 300 toward the side where it is on the base 100, i.e., the left-hand spring 110 pulls the slider 300 on the left to the left of the base 100, and the right-hand spring 110 pulls the slider 300 on the right to the right of the base 100, so that the two sliders 300 tend to be relatively far apart on the base 100. The end of the screw 500 may be abutted against the slide 300, the two slides 300 are pushed to approach each other by the screw 500, and the two slides 300 are pulled to move away from each other by the spring 110.

In some embodiments of the present utility model, as shown in fig. 2, a connection plate 120 is provided at the rear side of the base 100, and the connection plate 120 is provided with a plurality of mounting holes 121 in the height direction. Screws are used to lock the base 100 to the extrusion apparatus through the mounting holes 121. The mounting holes 121 at different height positions are used to adjust the mounting position of the base 100 with respect to the extrusion apparatus. Wherein a groove 330 is provided at the upper end of the slider 300. The recess 330 is used for placement of a level bar. When the base 100 is mounted on the extrusion apparatus, a level bar is placed in the groove 330, and the accuracy of mounting of the base 100 is observed.
