In the figure: 1. the roller bearing comprises a base, 2 parts of a carrier roller, 21 parts of a roller, 3 parts of a carrier roller bracket, 4 parts of a rotating roller, 5 parts of a rotating roller mounting seat, 51 parts of a supporting plate, 52 parts of a mounting rod, 6 parts of an elastic spring for an A-type shaft.

Detailed Description

The technical solutions in the implementation of the present invention will be clear from the following description and accompanying drawings, and the described embodiments are only some embodiments, not all embodiments, of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by a person of ordinary skill in the art without creative efforts belong to the protection scope of the present invention.

As shown in fig. 1 to 4, the embodiment of the utility model provides a lower bearing roller strutting arrangement of feeder, including base 1, bearing roller 2, bearing roller support 3, commentaries on classics roller 4 and commentaries on classics roller mount pad 5, be provided with a pair of parallel arrangement's bearing roller support 3 on the base 1, every the outside of bearing roller support 3 all is equipped with one with bearing roller support 3 parallel arrangement's commentaries on classics roller mount pad 5, bearing roller 2 installs in the recess of bearing roller support 3 through the roller bearing 21 at both ends, commentaries on classics roller 4 is hollow circular cylinder form, and quantity is two, and the suit is respectively on two commentaries on classics roller mount pads 5, and the both sides shirt rim of feeder shirt rim sticky tape is taken on two commentaries on classics rollers. The roller mounting base 5 comprises a supporting plate 51 and a mounting rod 52, the supporting plate 51 is arranged on the base 1, the mounting rod 52 is composed of two cylinders, the two cylinders are different in radius, the cylinder with the small radius is fixedly connected to the outer side of the supporting plate 51, the rollers 4 are respectively sleeved on the cylinders with the small radius in the two mounting rods 52, and the length of each roller 4 is smaller than that of the cylinder with the small radius on the mounting rod 52. The rotary roller 4 is sleeved on a cylinder with a small radius in the installation rod 52, one side of the cylinder is provided with the supporting plate 51, the other side of the cylinder with a large radius is provided with the cylinder with a large radius, and the rotary roller 4 can be limited, so that the phenomena of deviation and displacement of the rotary roller during operation are prevented. An A-shaped shaft elastic retainer ring 6 is arranged between the two sections of the cylinders of the mounting rod 52. The circlip 6 for the a-shaped shaft can further limit the position of the rotating roller 4, and can better prevent the rotating roller 4 from shifting from the rotating roller mounting seat 5.

Further, the carrier roller 2 is a ceramic carrier roller. The ceramic carrier roller has the advantages of wear resistance and oxidation resistance, can effectively prevent the rubber belt from deviating, reduces the local loss of the rubber belt, and prolongs the service life of the rubber belt.

Further, the roller 4 is a nylon carrier roller. The nylon carrier roller has the advantages of wear resistance, low friction coefficient and difficult clamping, does not easily damage the skirt edge, and has good dustproof and waterproof performances.

The working process is as follows: utilize bearing roller 2 to support the sticky tape, two change the shirt rim that roller 4 supported the sticky tape both sides, the sticky tape drives bearing roller 2 and changes roller 4 rotatory when moving, and the shirt rim rolling friction has reduced the wearing and tearing of shirt rim on changeing roller 4, simultaneously because the supporting role who changes the roller, the sticky tape both sides can not take place down the couch because of the gravity influence, have guaranteed the fender coal effect of shirt rim, have avoided the bearing roller to cut the emergence of phenomenon with the sticky tape, and then can prolong the life of sticky tape.

To sum up, the utility model discloses a set up in the both sides shirt rim below of feeder shirt rim sticky tape and change the roller and can provide good support to the shirt rim, not only improved the stability of shirt rim sticky tape operation, also can avoid sticky tape both sides to take place down the couch, thereby the life of sticky tape is prolonged to the bearing roller incised wound sticky tape of guarantee shirt rim, thereby can also avoid the sticky tape below.
