Description

Four-roller calender

Technical Field

The utility model belongs to the technical field of the compression roller mould, concretely relates to four-roller calender.

Background

The calender is a film which is formed by arranging two or more than two rollers according to a certain form and pressing and extending rubber or plastic into a certain thickness and surface shape at a certain temperature. However, the press delay of the existing calender needs an operator to continuously move the raw materials so as to ensure that the raw materials are uniformly mixed during calendering. For a four-roll calender, the material on the upper roll is difficult to move, so the operator generally only moves the material on the lower roll, and at this time, the material is still uneven.

Preferably, a sliding groove is formed in the axial direction of the connecting shaft, and the adjusting assembly moves in the sliding groove.

Preferably, the length of the cross bar is greater than the distance between the two adjustment bars.

Preferably, the upper press roll group and the lower press roll group are both composed of two press rolls, and the diameter of the press roll in the lower press roll group is larger than that of the press roll in the upper press roll group.

Preferably, two press rolls in the upper press roll group are arranged in an up-and-down state, and two press rolls in the lower press roll group are arranged in a horizontal direction.

Preferably, a driving motor for driving the upper press roll set to rotate is further arranged on the outer side of the upper part of the frame.

The beneficial effects of the utility model are embodied in: through set up adjusting part on last compression roller set, carry out the removal regulation about carrying out the rubber material automatically when calendering rubber, removed the manual work from to the removal of material on the compression roller set for the material calendering is more even.

Detailed Description

The technical scheme of the utility model is specifically explained below combining the embodiment, the utility model discloses a four-roll calender combines figure 1 to show, including frame 1, set up the compression roller group in frame 1. The compression roller group comprises a lower compression roller group arranged at the lower part of the frame 1 and an upper compression roller group arranged at the upper part of the frame 1. The upper compression roller group consists of two upper compression rollers 3 which are arranged in parallel from top to bottom, and the lower compression roller group consists of two lower compression rollers 2 which are arranged in parallel from left to right. And a driving motor 9 for driving the upper compression roller set to rotate is further arranged on the outer side of the upper part of the rack. And a motor shaft of the driving motor 9 is connected with one of the upper compression rollers, and the other upper compression roller can be driven to rotate through the upper compression roller connected with the motor. Since the lower roll stack undertakes the main calendering work, generally speaking, the diameter of the lower roll 2 is larger than the diameter of the upper roll 3.

When calendering, the material gets into down and rolls in the compression roller group and carry out the calendering, for the calendering is more thorough, needs to cut partly the material in the compression roller group down and enter into the compression roller group and carry out the calendering. Go up compression roller set one side and still be provided with the adjustment mechanism who is used for adjusting the material and removes to further assurance material can remove about in compression roller set at last compression roller set, more even cladding is to whole last compression roller promptly. The material passes through the adjusting mechanism and enters the upper compression roller set, and the adjusting mechanism axially moves along the surface of the upper compression roller set to drive the material to move on the upper compression roller set.

Specifically, adjustment mechanism includes parallel arrangement in the even axle 4 of last compression roller group one side, the cover is equipped with adjusting part on even axle 4. The axial of connecting axle 4 is seted up the spout, adjusting part removes in the spout. The adjusting assembly comprises a first adjusting rod 6 and a second adjusting rod 7 which are arranged in parallel, and the two adjusting rods are arranged on the connecting shaft in a divergent mode. The material is placed between the first adjusting rod 6 and the second adjusting rod 7. The adjusting component further comprises a cross rod 8 arranged on two sides of the adjusting rod, and the axis of the cross rod 8 is parallel to the axis of the pressing roller of the upper pressing roller group. The cross rod 8 better ensures that the adjusting assembly does not cause relative friction with the upper press roller 3 when moving axially, the upper press roller and the adjusting rod can be better protected, and the length of the cross rod 8 is greater than the distance between the two adjusting rods.

The following brief description is the working principle of the utility model:

waiting to roll the material and transporting to lower compression roller group through conveying mechanism and carrying out the calendering, after calendering a period, cutting the material on the lower compression roller, a slice passes through adjusting part and reentries into last compression roller group, and at this moment, the material between upper and lower compression roller group is connected. During press delay, the adjusting component axially moves on the connecting shaft to drive the rolled materials to axially move on the upper press roll group, so that the materials are kept more uniform when entering the lower press roll group.

Of course, the present invention has many specific embodiments, which are not listed here. All technical solutions formed by adopting equivalent substitutions or equivalent transformations fall within the scope of the present invention.
