Abstract
The utility model discloses an eliminate device of bearing play to roller interval influence belongs to two roller tablet press technical field. The device comprises a compression spring, a bearing seat device, an upper roller main bearing, a lower roller main bearing, an upper roller and a lower roller. Compare with the equipment of not installing compression spring and bearing frame device, the utility model discloses an install compression spring and bearing frame device additional on equipment after, the nut of adjustment compression spring top can be through bearing frame device with last roller hoist, makes the lower part that the play of going up the roller main bearing shifts to the bearing from last roller main bearing upper portion, has guaranteed that roller interval in process of products is before through and can not change owing to the play of going up the roller main bearing shifts when passing through, has eliminated the influence of bearing play to roller interval, has guaranteed the accuracy of goods thickness.
Description
Technical Field
The utility model belongs to the technical field of two roller tablet presses, a device of eliminating bearing play to roller interval influence is related to.
Background
Present two roller tablet presses, compression spring and bearing frame device are not installed, when interval A between roller and the lower roller in the adjustment, because antifriction bearing all has the bearing play, the dead weight of roller and bearing can make the bearing play all be in the upper portion of bearing, when the goods passes through roller interval A and presses into pieces, go up the roller when the goods passes through roll gap A, the lower part of bearing can be shifted from upper portion to the play of going up the roller bearing, interval A between two rollers can change, become A' ═ A + and go up roller bearing play, inconsistent with the size of A, influence the thickness of tablet.
SUMMERY OF THE UTILITY MODEL
In order to solve the problem, the utility model discloses an eliminate device of bearing play to roller interval influence.
The technical scheme of the utility model is that:
a device for eliminating the influence of bearing play on the distance between roller cylinders comprises a compression spring 1, a bearing seat device 2, an upper roller main bearing 3, a lower roller main bearing 4, an upper roller 5 and a lower roller 6.
The upper roller 5 is arranged on the two upper roller main bearings 3 and is positioned between the two upper roller main bearings 3. The lower roller 6 is positioned below the upper roller 5, is arranged on the two lower roller main bearings 4 and is positioned between the two lower roller main bearings 4. A support of a compression spring 1 is arranged on the upper part of a bearing seat of an upper roll main bearing 3; the two bearing seat devices 2 are respectively arranged on shaft heads of the two upper rollers 5, the tops of the bearing seat devices 2 are in fit connection with the compression springs 1 through pin shafts and nuts, the upper rollers 5 are lifted by adjusting the nuts, and the play of the upper roller main bearing 3 is transferred to the lower part of the upper roller main bearing from the upper part of the upper roller main bearing 3; and the distance A between the upper roller 5 and the lower roller 6 is adjusted by adjusting the position of the lower roller 6 up and down.
The equipment of compression spring 1 and bearing frame device 2 is not installed, when interval A between roller 5 and lower roll 6 is gone up in the adjustment, because antifriction bearing all has the bearing play, the dead weight of roller and bearing can make the bearing play all be in the upper portion of bearing, when the goods passed through roller interval A and is pressed into the piece, go up roller 5 when the goods passes through roll gap A, the play of going up roller main bearing 3 can shift the lower part of bearing from upper portion, interval A between two rollers can change, become A' ═ A + and go up roller main bearing play.
After installation compression spring 1 and bearing frame device 2, behind the nut of adjustment compression spring 1 top, just can will go up roller 5 through bearing frame device 2 and hoist, make the play of going up roller main bearing 3 transfer the lower part of bearing from last roller main bearing 3 upper portion, guaranteed that roller interval A in-process can not change owing to the play of going up roller main bearing 3 shifts when passing through before with, eliminated the influence of bearing play to roller interval to the accuracy of goods thickness has been guaranteed.
The utility model has the advantages that: the utility model provides an eliminate device of bearing play to roller interval influence, through install compression spring and bearing frame device additional on equipment after, the roller can eliminate because the change of interval between two rollers that the play of going up the roller base bearing arouses when calendering goods, has guaranteed the accuracy of goods thickness.
Drawings
Fig. 1 is a block diagram of the device of the present invention.
In the figure: 1 compressing the spring; 2, a bearing seat device; 3, an upper roller main bearing; 4, rolling the roller main bearing; 5, rolling; 6, rolling the rolls.
Detailed Description
The present invention will be further described with reference to the following examples and accompanying drawings.
As shown in fig. 1, a device for eliminating the influence of bearing play on the distance between rollers comprises a compression spring 1, a bearing seat device 2, an upper roller main bearing 3, a lower roller main bearing 4, an upper roller 5 and a lower roller 6.
The upper roller 5 is arranged on the two upper roller main bearings 3 and is positioned between the two upper roller main bearings 3. The lower roller 6 is positioned below the upper roller 5, is arranged on the two lower roller main bearings 4 and is positioned between the two lower roller main bearings 4. A support of a compression spring 1 is arranged on the upper part of a bearing seat of an upper roll main bearing 3; the two bearing seat devices 2 are respectively arranged on shaft heads of the two upper rollers 5, meanwhile, the top of each bearing seat device 2 is connected with a pin shaft, and the pin shaft sequentially penetrates through a support of the compression spring 1, the compression spring 1 and a nut to be connected. Behind the nut of adjustment compression spring 1 top, just can will go up roller 5 through bearing frame device 2 and hoist, the lower part of bearing is shifted from last roller main bearing 3 upper portion to the play that makes last roller main bearing 3, the adjustment of interval A between roller 5 and the lower roll 6 is realized to the position of adjusting lower roll 6 from top to bottom in the rethread, interval A in process of being worked in the middle of the roller can not change because the play that goes up roller main bearing 3 shifts when passing through before the article, the influence of bearing play to roller interval has been eliminated, the accuracy of goods thickness has been guaranteed.
