Abstract
The utility model discloses a roller-gap adjusting device of a three-roller machine. The roller-gap adjusting device comprises bearing steel beams, bearing shafts and adjusting springs, wherein the rollers of the three-roller machine comprise a front roller, a middle roller and a rear roller; the positions under the front roller, the middle roller and the rear roller are respectively provided with one bearing steel beam; the two ends of the bearing steel beams are provided with bearing brackets; the front roller, the middle roller and the rear roller are respectively arranged on the bearing brackets at the two ends of the bearing steel beams by the bearing shafts; and the adjusting springs are respectively between the middle position of the bearing steel under the front roller and the middle position of the bearing steel beam under the middle roller and between the middle position of the bearing steel beam under the rear roller and the middle position of the bearing steel beam under the middle roller. The roller-gap adjusting device disclosed by the utility model has the advantages that by adjustment for the size of the elasticity of the adjusting spring at the middle position, the elasticity of the spring is uniformly distributed to the left sides and the right sides of the front roller, the middle roller and the rear roller by the bearing steel beams, so that the gaps between the rollers are controlled to be uniform and consistent, the fineness of pressed materials is same and the product quality and the production efficiency are high.
Description
Technical field
The utility model relates to a kind of three-roller device, particularly a kind of drum clearance adjustment device of three-roller.
Background technology
Current three-roller is by preliminary roller, and central roll and rear roller form, and wherein central roll is the fixed stationary roll in position, and preliminary roller and rear roller regulate gap by spring and central roll separately.Before and after the right and left of roller respectively have a spring, by Compress Spring, change separately the gap with central roll.But because the coefficient of elasticity of each spring can not be in full accord, degree of aging also has difference, roller the right and left is to the pressure of spring also can not be identical separately, therefore it is in full accord to be difficult to the gap of the left and right sides between adjusting roller, thereby cause the fineness of pressure rolling material also can be not identical, have a strong impact on product quality and production efficiency.
Utility model content
For solving the problems of the technologies described above, the purpose of this utility model is to provide a kind of drum clearance adjustment device of three-roller that can even regulation roller gap.
For realizing above-mentioned technical purpose, reach above-mentioned technique effect, the utility model is achieved through the following technical solutions: a kind of drum clearance adjustment device of three-roller, comprise load-bearing girder steel, load-bearing axle and regulating spring, the roller of described three-roller comprises preliminary roller, central roll and rear roller, described preliminary roller, the below of central roll and rear roller is respectively equipped with the load-bearing girder steel described in, the two ends of load-bearing girder steel are provided with support bracket, preliminary roller, central roll and rear roller are installed on the support bracket at load-bearing girder steel two ends by load-bearing axle respectively, between the centre position of the centre position of the load-bearing girder steel of described preliminary roller below and the load-bearing girder steel of central roll below, between the centre position of the centre position of the load-bearing girder steel of rear roller below and the load-bearing girder steel of central roll below, be separately installed with the regulating spring described in.
Further, described load-bearing girder steel is square column.
The beneficial effects of the utility model are: the drum clearance adjustment device of the utility model three-roller is merged into one by the spring that is distributed in both sides between preliminary roller and central roll and is positioned at middle regulating spring, the spring that is distributed in both sides between rear roller and central roll is also merged into one and be positioned at middle regulating spring, spring force is uniformly distributed the left and right sides to preliminary roller, central roll and rear roller by load-bearing girder steel, and the elastic force of the regulating spring in the middle of being positioned at by adjusting is controlled the gap between roller.This design can be so that the gap uniformity between roller makes the fineness of pressure rolling material identical, and product quality and production efficiency are high.
Accompanying drawing explanation
Fig. 1 is the structural representation of the drum clearance adjustment device of the utility model three-roller.
The specific embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail, thereby so that advantage of the present utility model and feature can be easier to be it will be appreciated by those skilled in the art that, protection domain of the present utility model is made to more explicit defining.
As shown in Figure 1, a kind of drum clearance adjustment device of three-roller, comprise load-bearing girder steel 1, load-bearing axle 2 and regulating spring 3, the roller of described three-roller comprises preliminary roller 4, central roll 5 and rear roller 6, described preliminary roller 4, the below of central roll 5 and rear roller 6 is respectively equipped with the load-bearing girder steel 1 described in, the two ends of load-bearing girder steel 1 are provided with support bracket 7, preliminary roller 4, central roll 5 and rear roller 6 are installed on the support bracket 7 at load-bearing girder steel 1 two ends by load-bearing axle 2 respectively, between the centre position of the centre position of the load-bearing girder steel 1 of described preliminary roller 4 belows and the load-bearing girder steel 1 of central roll 5 belows, between the centre position of the centre position of the load-bearing girder steel 1 of rear roller 6 belows and the load-bearing girder steel 1 of central roll 5 belows, be separately installed with the regulating spring 3 described in.Wherein, load-bearing girder steel 1 is square column.
The central roll 5 of three-roller is the fixed stationary roll in position.The drum clearance adjustment device of the utility model three-roller is merged into one by the spring that is distributed in both sides between preliminary roller 4 and central roll 5 and is positioned at middle regulating spring, the spring that is distributed in both sides between rear roller 6 and central roll 5 is also merged into one and be positioned at middle regulating spring.When adjusting is positioned at the elastic force of middle regulating spring 3, spring force is uniformly distributed the left and right sides to preliminary roller 4, central roll 5 and rear roller 6 by load-bearing girder steel 1, makes the gap uniformity between roller.The elastic force of the utility model regulating spring in the middle of being positioned at by adjusting is controlled the gap between the roller of three-roller, makes the fineness of pressure rolling material identical, and product quality and production efficiency are high.
The foregoing is only embodiment of the present utility model; not thereby limit the scope of the claims of the present utility model; every equivalent structure or conversion of equivalent flow process that utilizes the utility model description and accompanying drawing content to do; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present utility model.
