Abstract

The utility model discloses an improvement compression roller device of draft machine, including roller and bearing, the both ends of roller are equipped with two bearings respectively, and it makes two bearing intervals set up still to overlap on the roller between two bearings to be equipped with the separation sleeve. The improved press roller device of the drafting machine enables the operation temperature of the press roller to be low and reduces shaking.

Description

Improved compression roller device of drafting machine

The technical field is as follows:

the utility model relates to an improvement compression roller device of draft machine.

Background art:

because the service time of the drafting machine is long, the vulnerable parts are gradually aged and broken down. The compression roller of the drafting machine feeds the precursor into the hot plate at a constant speed, if the compression roller rotates abnormally, the filament bundle is caused to jump, the filament bundle can not be ensured to enter the hot plate at a constant speed for heating and stretching, and therefore the quality of the product is unstable. The original press roller is composed of: a pair of 6201 bearings, a roll shaft and a press roll jacket. The stability of the compression roller can be maintained only by one 6201 bearing, the long-time rotation causes the abrasion of the groove and the steel ball of the bearing, the clearance between the inner circle and the outer circle of the bearing is increased, and the compression roller shakes in the production process. Therefore, the filament bundle passing through the compression roller can not stably pass through the compression roller, and even is not completely pressed on the roller by the compression roller, so that the filament bundle slips and is not stretched in place, and the product has hidden quality troubles.

The utility model has the following contents:

the utility model aims to solve the technical problem that an improvement compression roller device of the draft machine that can even running, reduce and rock is provided.

The technical solution of the utility model is that, an improvement compression roller device of draft machine is provided, including roller and bearing, the both ends of roller are equipped with two bearings respectively, and it makes two bearing intervals set up to still overlap on the roller between two bearings to be equipped with the separation sleeve.

Compared with the prior art after the structure more than adopting, the utility model has the advantages of it is following: by adding one pair of bearings, the stability of the press roller is established on a plane borne by the two pairs of bearings, but not on a point of the previous pair of bearings, so that the stability is well improved, the service cycle can be prolonged, and the maintenance cost can be reduced.

Preferably, the isolation sleeve is a nylon sleeve, and the length of the nylon sleeve is 4-6 cm.

Further, the outer surface of the roll shaft is also provided with a rubber layer, and the rubber layer is coated on the surface of the roll shaft between the inner bearings at the two ends of the roll shaft.

Description of the drawings:

fig. 1 is a schematic structural diagram of the present invention.

The specific implementation mode is as follows:

the invention will be further explained with reference to the drawings and the detailed description below:

as shown in fig. 1, an improved compression roller device of a drafting machine comprises a roller shaft 1 and bearings, two bearings 2 are respectively arranged at two ends of the roller shaft 1, an isolating sleeve 3 is further sleeved on the roller shaft between the two bearings 2 to enable the two bearings to be arranged at intervals, the isolating sleeve 3 is a nylon sleeve, the length of the nylon sleeve is 4-6cm, the nylon sleeve is sleeved on the roller shaft, 6203 bearings can be selected as the bearings, the bearings are sleeved on the roller shaft, and gaps are formed between the bearings and the bearings through the nylon sleeve.

The foregoing is illustrative of the preferred embodiments of the present invention only, and is not to be construed as limiting the claims. All the equivalent structures or equivalent flow changes made by using the contents of the specification and the attached drawings of the utility model are included in the patent protection scope of the utility model.
