In order to overcome the defects of the prior art, the utility model provides a device for adjusting the gap of a roller by an inclined block,
the utility model adopts the technical proposal that: the device for adjusting the gap between the rollers comprises an upper roller and a lower roller, wherein two ends of the upper roller are mounted on an upper bearing seat, two ends of the lower roller are mounted on a lower bearing seat, a sliding inclined block is arranged between the upper bearing seat and the lower bearing seat, an upper end inclined plane of the sliding inclined block is in sliding contact with a lower end inclined plane of the upper bearing seat, a lower end flat surface of the sliding inclined block is in sliding contact with an upper end flat surface of the lower bearing seat, a screw sleeve is mounted on the sliding inclined block and sleeved on a lead screw, and one end of the lead screw is provided with a driving mechanism for driving the lead screw to rotate.
Furthermore, an oil cylinder is arranged above the upper roller, and the oil cylinder compresses the upper roller to provide constant pressure for the upper roller.
Furthermore, the screw sleeve is divided into a left screw sleeve and a right screw sleeve, the left screw sleeve and the right screw sleeve are respectively arranged at two ends of the sliding inclined block, and the lead screw penetrates through the sliding inclined block and drives the sliding inclined block to move through the left screw sleeve and the right screw sleeve.
Further, the inclination of the upper surface of the sliding inclined block is 1: 20.
Further, the driving mechanism comprises a servo motor and a speed reducer
Furthermore, two ends of the lead screw are mounted on the wall plate through a bearing and a bearing seat.
The utility model has the advantages that: this device passes through servo motor drive sloping block regulation clearance, and through the displacement (accessible grating chi detects) that detects the sloping block, alright accuracy master fast adjusts the roller clearance, and such digital regulation has improved operation convenience and yield, has reduced the raw materials waste.
Compared with a common rolling distance adjusting structure, the device avoids the influence of machining errors on the adjusting precision, has more accurate adjusting value, saves the operation time, reduces the labor intensity of workers, and improves the yield of products.

Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
As shown in fig. 1, the roller gap adjusting device with the inclined block comprises an upper roller 1 and a lower roller 2, wherein two ends of the upper roller 1 are mounted on an upper bearing seat 3, two ends of the lower roller 2 are mounted on a lower bearing seat 4, a sliding inclined block 5 is arranged between the upper bearing seat 3 and the lower bearing seat 4, an upper end inclined plane of the sliding inclined block 5 is in sliding contact with a lower end inclined plane of the upper bearing seat 3, a lower end flat plane of the sliding inclined block 5 is in sliding contact with an upper end flat plane of the lower bearing seat 4, the sliding inclined block 5 is provided with a left screw sleeve 6 and a right screw sleeve 7, the two screw sleeves are sleeved on a screw rod 8 at the same time, the screw rod 8 penetrates through the sliding inclined block 5, and one end of the screw rod 8 is provided with a driving mechanism for driving.
The utility model discloses in, the top of going up roller 1 is equipped with hydro-cylinder 9, hydro-cylinder 9 compresses tightly roller 1 and provides constant pressure to it. The driving mechanism mainly comprises a servo motor 10 and a speed reducer 11
The utility model discloses a theory of operation does: when a calender produces products, a servo motor 10 drives a screw rod 8 through a speed reducer 11, the screw rod 8 rotates forwards and reversely to drive a left screw sleeve and a right screw sleeve which are arranged on a sliding inclined block 5, and the sliding inclined block 5 is driven to move left and right through the left screw sleeve and the right screw sleeve. The sliding inclined block 5 and the inclined plane of the upper roller bearing seat slide to enable the upper roller 1 to ascend or descend, the oil cylinder 9 provides downward constant pressure during working, and the roller ascends and descends by 1mm as the inclination of the sliding inclined block 5 is 1:20 and the inclined block moves left and right by 20 mm. Therefore, as long as the moving distance of the sliding inclined block 5 is detected through the grating ruler, the lifting stroke value of the upper roller can be known, and the manufacturing error of the lead screw nut does not influence the detection accuracy of the grating ruler, so that the roller gap can be accurately and quickly adjusted.
The foregoing illustrates and describes the principles, general features, and advantages of the present invention. It should be understood by those skilled in the art that the above embodiments do not limit the scope of the present invention in any way, and all technical solutions obtained by using equivalent substitution modes and the like fall within the scope of the present invention.
