Abstract
The utility model relates to a friction device with pre-tightening buffer for a scroll machine, one end of a main shaft is penetrated with a friction disk, a friction base, a locking apparatus and a pressure spring in turn after passing through a supporting base, the friction base is matched and connected with the locking apparatus, the end of the main shaft passing through the pressure spring and a pressure regulating nut are in the screw connection, the friction disk and the supporting base are tightly contacted to form a compacted matching contact face; compared to the prior art, the utility model has advantages that the structure is novel and simple, as a result of providing with the friction device with the pre-tightening buffer on a driven roller drum, the resistance force of the driven roller drum can be increased, being followed by instant locking to the main shaft of the driven roller drum by the locking apparatus, thereby effectively preventing the forward rotating of the driven roller drum caused by the inertia, ensuring the scroll to be kept in the tightening state all the time no matter what the scroll machine is in the stopping state or the running state, ensuring the scroll content not to be creping, being without folded corners and fringes, and greatly improving the production efficiency, the friction device with the pre-tightening buffer has advantages of low production cost, reliable performance, environmental protection, and can save energy resources.
Description
[technical field]
The utility model relates to the strigil technical field, and specifically a kind of scroll machine is with being with pre-locking buffering strigil.
[background technology]
In the market, the use of scroll machine is more and more frequent, and its operation principle is also similar substantially.Vertically hung scroll cloth twists on active roll tube and the passive roller, and when active roll tube rotated, active roll tube just drove passive roller and rotates together, thereby carries out work.Yet when the active roll tube of scroll machine stops operating, passive roller is because inertia, can continue to turn an angle forward, thereby cause vertically hung scroll cloth relaxation to occur, defective such as make that the print content on the vertically hung scroll cloth is wrinkling, knuckle, striped, print content are crooked.Address this problem in order to eliminate such defective, to press for.
[utility model content]
The purpose of this utility model is exactly will solve above-mentioned deficiency and provide a kind of scroll machine with being with pre-locking buffering strigil.Passive roller also continues to rotate forward owing to inertia after having prevented the scroll machine active roll tube to stop operating effectively.
Design scroll machine for achieving the above object with being with pre-locking buffering strigil, comprise passive roller main shaft and be installed in supporting seat on the main shaft, described main shaft one end passes behind the supporting seat cross-under friction plate, friction seat and locking device and stage clip successively, the described friction seat locking device that is connected, closely contact between the described spindle nose that passes behind the stage clip look nut that is threaded, described friction plate and supporting seat and form the contact-making surface of compression fit.
Described locking device comprises disc spring seat, disc spring, in the described disc spring seat disc spring is housed, and described friction seat is a T shape roller structure, and the trundle of described friction seat partly is installed in the center of described disc spring.
The contact-making surface that described supporting seat and friction plate form compression fit is a rubbing surface.
Described friction plate is made integrative-structure with the friction seat.
The utility model is compared with prior art, novel structure, simply, because passive roller is provided with and is with pre-locking buffering strigil, increased the resistance of passive roller, add locking device passive roller main shaft is carried out moment locking, thereby prevent passive roller more effectively because inertia rotates forward, no matter guaranteed scroll machine in running or halted state, vertically hung scroll remains tight state, guarantee that the vertically hung scroll content is wrinkle resistant, no knuckle, no striped, greatly improved production efficiency, and this pre-locking buffering strigil cost of manufacture is low, dependable performance, a large amount of energy are saved in environmental protection, are worthy of popularization.
[description of drawings]
Fig. 1 is a structural representation of the present utility model;
Among the figure: 1 is that supporting seat, 2 is main shaft for look nut, 8 for stage clip, 7 for disc spring seat, 6 for disc spring, 5 for friction seat, 4 for friction plate, 3.
[specific embodiment]
Further specify below below in conjunction with accompanying drawing the utility model being done:
As shown in Figure 1, the utility model comprises passive roller main shaft 8 and is installed in supporting seat 1 on the main shaft, described main shaft one end passes behind the supporting seat cross-under friction plate 2, friction seat 3 and locking device and stage clip 6 successively, the described friction seat locking device that is connected, closely contact between the described spindle nose that passes behind the stage clip look nut 7 that is threaded, described friction plate and supporting seat and form the contact-making surface of compression fit.The contact-making surface that described supporting seat and friction plate form compression fit is a rubbing surface.
Described locking device comprises disc spring seat 5, disc spring 4, in the described disc spring seat disc spring is housed, and described friction seat 3 is a T shape roller structure, and the trundle of described friction seat partly is installed in the center of described disc spring.
In addition, friction plate of the present utility model can also be made integrative-structure with the friction seat.
Design principle of the present utility model: owing to closely contact between friction plate and the supporting seat, thereby between have certain coefficient of friction, make main shaft at the certain resistance of Shi Junyou that still stops operating that turns round, when the scroll machine active roll tube stops operating the hub disk spring abutment because inertia makes disc spring moment locking friction seat 3 in the dish seat, be subjected to a great resistance again in main shaft moment of this passive roller of while.Thereby prevent passive roller more effectively because inertia rotates forward, no matter guaranteed scroll machine in running or halted state, vertically hung scroll remains tight state.
The design of stage clip and look nut is for the ease of regulating the frictional force between friction plate and the supporting seat.
