Description
Technical field
The utility model relates to paper making equipment technical field, is specially a kind of centre frame of vacuum carrying roller.
Background technology
After paper pulp being carried out uniform treatment in papermaking operation, owing to there being a large amount of moisture in paper pulp, need squeezing to get rid of moisture in the forming process of paper product, vacuum furnace holder is the parts of conventional dehydration on paper machine.The centre frame of existing vacuum carrying roller is circular, and the roller supporting arm that the three Ge Kexiang centers that are provided with adjust simultaneously, in the inner termination of roller supporting arm, roller is housed, when centralized positioning, vacuum furnace holder is through centre frame, and by the roller supporting of three on centre frame, during control work pieces process, stressed generation bends.The centre frame of this structure, due to frame, this is annular, vacuum carrying roller will sideways through centre frame, consider the huge volume and weight of vacuum carrying roller, such centre frame is waste time and energy in use, and three rollers adjust simultaneously, due to the error of installing, easy appearance three rollers can not support to place simultaneously, control the weak effect of workpiece bows.
Utility model content
The purpose of this utility model is the problem overcoming above-mentioned prior art, provides a kind of centre frame of vacuum carrying roller, and its structure is simple, and vacuum carrying roller can easily be placed on centre frame, improve machining accuracy, time saving and energy saving.
The purpose of this utility model is achieved through the following technical solutions: a kind of centre frame of vacuum carrying roller, it is characterized in that: comprise centre frame base, the two ends of described centre frame base upper surface are respectively arranged with turning rolls, described turning rolls is provided with roller, the both sides of described turning rolls are drilled with through hole respectively, on described centre frame base, the below of corresponding described through hole is drilled with T-slot, described turning rolls is fixedly connected with described centre frame base with described T-slot through described through hole by T-slot bolt, the lower end of described turning rolls is fixedly connected with connector by bolt, screw thread is provided with in described connector, the two ends of described centre frame base are established respectively and are provided with screw mandrel, described connector is connected with described wire rod thread.
Further, the centre of described centre frame base is provided with circular groove;
The two ends of described turning rolls are respectively equipped with roller mounting slot, described roller is fixedly fitted on described turning rolls by roller pressing plate, described roller pressing plate is fixedly connected with described turning rolls by bolt, and the bearing touch place of described roller pressing plate and described roller is provided with arc-shaped concave.
The axle head of described screw mandrel and described centre frame base contacts is also provided with axle sleeve.
The centre frame of vacuum carrying roller of the present utility model is by being arranged on turning rolls on centre frame base and roller positioning vacuum carrying roller, frictional force between vacuum carrying roller and centre frame body converts force of rolling friction to, reduce vacuum carrying roller by the situation of locking, simultaneously, by the drive of roller, make workpiece uniform force, achieve the location to vacuum carrying roller two ends and support, ensure the concentricity of vacuum carrying roller, the centre frame avoiding circular ring type is difficult to the shortcoming of laying vacuum carrying roller, vacuum carrying roller can easily be placed on centre frame, improve machining accuracy, time saving and energy saving, by screw mandrel movable idler wheel shelf, also the support to differential roller footpath can be realized when turning rolls need not be changed.
Accompanying drawing explanation
Fig. 1 is the broken section structural representation of the centre frame of a kind of vacuum carrying roller described in the utility model;
Fig. 2 be Fig. 1 A-A to partial schematic sectional view.
Detailed description of the invention
According to drawings and embodiments the utility model is described in further detail below.
As Fig. 1, shown in Fig. 2, the centre frame of a kind of vacuum carrying roller described in the utility model embodiment, comprise centre frame base 1, the two ends of centre frame base 1 upper surface are respectively arranged with turning rolls 2, turning rolls 2 is provided with roller 3, the both sides of turning rolls 2 are drilled with through hole respectively, on centre frame base 1, the below of corresponding through hole is drilled with T-slot 4, T-slot bolt 5 is each passed through through hole and is fixedly connected with centre frame base 1 by turning rolls 2 with T-slot 4, the lower end of turning rolls 2 is fixedly connected with connector 7 by bolt 6a, screw thread is provided with in connector 7, the two ends of centre frame base 1 are separately installed with screw mandrel 9, connector 7 is threaded with screw mandrel 9.
Further, the centre of centre frame base 1 is provided with circular groove 10, the two ends of turning rolls 2 are respectively equipped with roller mounting slot 11, roller 3 is fixedly fitted on turning rolls 2 by roller pressing plate 12, roller pressing plate 12 is fixedly connected with turning rolls 2 by bolt 6b, roller pressing plate 12 is provided with arc-shaped concave 13 with the bearing touch place of roller 3, and the axle head that screw mandrel 13 contacts with centre frame base 1 is also provided with axle sleeve 8.
The centre frame of vacuum carrying roller is by being arranged on turning rolls 2 on centre frame base 1 and roller 3 positioning vacuum carrying roller, frictional force between vacuum carrying roller and centre frame body converts force of rolling friction to, reduce vacuum carrying roller by the situation of locking, simultaneously, by the drive of roller 3, make workpiece uniform force, achieve the location to vacuum carrying roller two ends and support, ensure the concentricity of vacuum carrying roller, the centre frame avoiding circular ring type is difficult to the shortcoming of laying vacuum carrying roller, vacuum carrying roller can easily be placed on centre frame, improve machining accuracy, time saving and energy saving, by screw mandrel 3 movable idler wheel shelf 2, also the support to differential roller footpath can be realized when turning rolls 2 need not be changed, accurate thread transmission is adopted between leading screw and connector 7, thus make the centre frame of screw structure realize fine adjustment, good positioning effect.
What the centre of centre frame base 1 was provided with circular groove 10 is arranged so that centre frame goes for the vacuum carrying roller varied in size more, avoids the contact of vacuum carrying roller and centre frame base.
Roller pressing plate 12 be arranged so that the roller 3 being convenient for changing different size, make centre frame be applicable to multiple different vacuum carrying roller further, the wide usage of centre frame is good.
The foregoing is only and embodiment of the present utility model is described; be not limited to the utility model; for a person skilled in the art; all within spirit of the present utility model and principle; any amendment of doing, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
