Abstract
The invention discloses a pressure rolling friction regulating system. The pressure rolling friction regulating system comprises a support, a regulating bolt, a spring, a pushing plate, a sleeve, a slide block, a rotating shaft, a connecting rod, a polished rod, friction drums, a C-shaped sleeve clamp and other components. When the pressure rolling friction regulating system is used, a bed sheet is placed between the two friction drums, the bolt on the tail part of the sleeve is regulated, the pushing plate pushes the spring to move forward, the slide block moves forward under the action of elasticity of the spring, and the two friction drums tightly press against each other under the action of a lever principle to increase the friction between the two friction drums. The pressure rolling friction regulating system is applicable to medical paper bed sheets made of different materials and having different thickness and solves the slipping problem caused by a non-uniform stress under an ordinary bed sheet changing condition, thus improving the reliability and stability of automatic bed sheet changing equipment of a medical examination bed.
Description
Technical field
The invention belongs to electromechanical integration technology area, relate to a kind of nip drum friction adjustable system.
Background technology
For a long time, medical resource is in short supply, some inspections of patient, and such as B ultrasonic, CT, queuing phenomena is very serious, and sheet all is manually to change in the checking process, has reduced to a certain extent the efficient that checks, has increased simultaneously medical personnel's workload.Therefore in checking process, substantially be difficult to accomplish to check sheet " people one changes ".For above-mentioned present situation, provide a kind of novel Medical treatment examining table automatically more the equipment of changing the sheet seem very necessary.The application of this equipment can guarantee to check sheet " people one changes ", outer review time and the human resources of occupying volume not again, and can discard the sheet environmental protection and reclaim.Yet the sheet transmission is a most important process in the equipment, need to have reliable and stable frictional force to realize.A kind of effective ways that the present invention addresses the above problem just.
Summary of the invention
The present invention is directed to the Medical treatment examining table equipment that automatically more changes the sheet, require to realize reliable and stable replacing operation for the medico paper sheet of unlike material, different-thickness, and a kind of nip drum frictional force adjustable mechanism that proposes.
The present invention includes support, adjusting bolt, spring, push pedal, sleeve, slide block, rotating shaft, connecting rod, the first polished rod, the second polished rod, the first friction cylinder, the second friction cylinder and C jacket collet chuck.
The first friction cylinder is enclosed within the stage casing of the first polished rod, forms interference fit, can rotate together; The two ends of the first polished rod are installed on the support by bearing, and an end of the first polished rod links to each other with motor by shaft coupling; The second friction cylinder is enclosed within the stage casing of the second polished rod, forms interference fit, can rotate together, and two friction cylinders contact with each other extruding.
150 ° of connecting rod stage casing bendings link to each other by rotating shaft with support, and an end of connecting rod is enclosed within the end of the second polished rod, and the other end and slide block are rotationally connected; Slide block and sleeve matched in clearance can move back and forth; Adjusting bolt is connected with the sleeve tailing screw flight, and the adjusting bolt and the push pedal that screw in sleeve inner are connected; Between push pedal and slide block, spring is housed; C jacket collet chuck is fixed in the support inboard with sleeve.
During use, as long as the adjusting bolt of regulating sleeve afterbody just can change two pressure between the friction cylinder, thereby make equipment have enough frictional force to drag sheet, realize the automatic replacing of sheet.
Beneficial effect of the present invention is as follows:
This scheme that provides, can be used for the Medical treatment examining table equipment that automatically more changes the sheet, can try out the medico paper sheet in unlike material, thickness, solved in the general replacement sheet situation, the problem of skidding that exists because of discontinuity, thus automatically more the change the sheet reliability and stability of equipment of Medical treatment examining table improved.
Description of drawings
Fig. 1 is installation diagram of the present invention.
Fig. 2 is that the C of Fig. 1 is to view.
Among the figure, support 1, adjusting bolt 2, spring 3, push pedal 4, sleeve 5, slide block 6, rotating shaft 7, connecting rod 8, polished rod 9, polished rod 10, friction cylinder 11, friction cylinder 12, C jacket collet chuck 13.
The specific embodiment
Below in conjunction with accompanying drawing the present invention is further described.
As shown in Figure 1, the present invention includes support 1, adjusting bolt 2, spring 3, push pedal 4, sleeve 5, slide block 6, rotating shaft 7, connecting rod 8, the first polished rod 9, the second polished rod 10, the first friction cylinder 11, the second friction cylinder 12, C jacket collet chuck 13.
The first friction cylinder 11 is enclosed within the stage casing of the first polished rod 9, forms interference fit, can rotate together; The two ends of the first polished rod 9 are installed on above the support by bearing, and wherein an end links to each other with motor by shaft coupling; The second friction cylinder 12 is enclosed within the stage casing of the second polished rod 10 equally, forms interference fit, can rotate together, and two friction cylinders contact with each other extruding.
150 ° of connecting rod 8 stage casings bendings link to each other by rotating shaft 7 with support, and an end of connecting rod 8 is enclosed within the end of the second polished rod 10, and the other end and slide block 6 are rotationally connected; Slide block 6 and sleeve 5 matched in clearance can move back and forth; Adjusting bolt 2 is connected with sleeve 5 tailing screw flights, and the bolt and the push pedal 4 that screw in sleeve inner are connected; Between push pedal 4 and slide block 6, spring 3 is housed; C jacket collet chuck 13 is fixed in support 1 inboard with sleeve 5.
The present invention uses work process as follows:
As shown in Figure 1, in the time of use, sheet rotates to drag sheet around between two friction cylinders by the driven by motor friction cylinder.When having enough frictional force or discontinuity, can not skid.
As shown in Figure 2, at this moment, the bolt of regulating sleeve afterbody, push pedal promotes spring and moves forward, and under the effect of spring force, slide block moves forward.Under the effect of lever principle, so that two friction cylinders compress, increase the frictional force between two friction cylinders.
