Abstract
The utility model relates to a high friction coefficient friction device with pre-tightening buffer for a scroll machine, including a driven roller cylinder main shaft and a supporting seat arranged on the main shaft. One end of the main shaft passes through a friction sheet, a friction seat, a pressure spring and a pressure regulating nut in consequence after passing through the supporting seat. Two end surfaces of the friction sheet are respectively in close contact with the supporting seat and the friction seat to form compaction cooperated contact surfaces. The friction sheet is fixedly connected with the supporting seat. Compared to the prior art, in the utility model, the structure is novel and simple; because the driven roller cylinder is provided with the friction device with pre-tightening buffer employing the double friction surface structure, the generated friction is large and adjustable, the resistance of the driven roller cylinder is increased, the forward rotation of the driven roller cylinder caused by inertia is more effectively prevented, the scroll machine is guaranteed that no matter in a running or stop state, the scrolls are kept in a tight state, the scrolls are kept without wrinkling, angle folding or strip forming, and the production efficiency is largely raised.
Description
[technical field]
The utility model relates to the strigil technical field, and specifically a kind of scroll machine of great friction coefficient is with band pretension buffering strigil.
[background technology]
In the market, the use of scroll machine is more and more frequent, and its operation principle is also similar basically.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.
In addition, patent publication No. is: CN201685542U, CN201685543U, the disclosed scroll machine of these two utility model patents is with band pretension buffering strigil, though solved above-mentioned defective.But also exist weak point on its structure: the frictional force of strigil is still big inadequately, so need further be resolved.
[utility model content]
The purpose of the utility model be exactly to solve above-mentioned deficiency and scroll machine that a kind of great friction coefficient is provided with band pretension buffering strigil.The frictional force of strigil is big, and can regulate, and passive roller also continues to rotate forward owing to inertia to have prevented the scroll machine active roll tube to stop operating afterwards effectively.
The scroll machine that designs a kind of great friction coefficient for the realization above-mentioned purpose is with band pretension buffering strigil; Comprise passive roller main shaft and be installed in the supporting seat on the main shaft; Said main shaft one end passes behind the supporting seat cross-under friction plate, friction seat, stage clip and look nut successively; Said supporting seat, friction seat are installed on the main shaft through bearing; Said friction plate is through the axle key main shaft that is connected, and the both ends of the surface of said friction plate closely contacts and form the contact-making surface of compression fit, said friction plate fixed connection supporting seat respectively with between supporting seat, the friction seat.
The both ends of the surface of said friction plate closely contact and the contact-making surface that forms compression fit is a rubbing surface respectively with between supporting seat, the friction seat.
Be provided with a friction plate between said supporting seat and the friction plate, said friction plate is fixedly connected supporting seat, closely contacts between the other end of said friction plate and the friction plate and forms the contact-making surface of compression fit, and said contact-making surface is a rubbing surface.
Said friction plate adopts the fluoroplastics material to process.
Said friction plate adopts straight pin to be fixedly connected supporting seat.
The utility model is compared with prior art, and novel structure, simple adopt two rubbing surface structures because passive roller is provided with band pretension buffering strigil, thereby the frictional force that produces is big; And can regulate, increased the resistance of passive roller, prevent passive roller more effectively because inertia rotates forward, no matter guaranteed that scroll machine is in running or halted state; Vertically hung scroll remains tight state, guarantees wrinkle resistant, the no knuckle of vertically hung scroll content, no striped, has greatly improved production efficiency; And this pretension buffering strigil cost of manufacture is low, dependable performance; Mass energy is practiced thrift in environmental protection, is worthy of popularization.
[description of drawings]
Fig. 1 is the structural representation of the utility model;
Among the figure: 1 is that supporting seat, 2 is main shaft for look nut, 12 for stage clip, 11 for bearing, 10 for straight pin, 9 for friction seat, 8 for friction plate, 7 for hexagonal axle sleeve, 6 for friction plate, 5 for bearing holder (housing, cover), 4 for bearing, 3.
[specific embodiment]
Further specify below below in conjunction with accompanying drawing the utility model being done:
Shown in accompanying drawing 1; The utility model comprises passive roller main shaft 12 and is installed in the supporting seat 1 on the main shaft; Said main shaft one end passes behind the supporting seat cross-under friction plate 6, friction seat 7, stage clip 10 and look nut 11 successively; Said supporting seat, friction seat are installed on the main shaft through bearing 2,9; Said friction plate is through hexagonal axle sleeve 5, the axle key main shaft that is connected, and the both ends of the surface of said friction plate closely contact and form the contact-making surface of compression fit respectively with between supporting seat, the friction seat, and said contact-making surface is a rubbing surface.Said friction plate adopts straight pin 8 to be fixedly connected supporting seat.
In addition; Can also be provided with a friction plate 4 between supporting seat of the utility model and the friction plate; Said friction plate is fixedly connected supporting seats through straight pin 8, closely contacts between the other end of said friction plate and the friction plate and forms the contact-making surface of compression fit, and said contact-making surface is a rubbing surface.Said friction plate adopts the fluoroplastics material to process.
The design principle of the utility model: owing to closely contact between friction plate and supporting seat (or the friction plate on the supporting seat), the friction; Thereby between have certain coefficient of friction; Make main shaft at the running certain resistance of Shi Junyou that still stops operating, main shaft moment of passive roller receives a great resistance again after the scroll machine active roll tube stops operating.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 supporting seat (or the friction plate on the supporting seat), the friction seat.
