Abstract

The utility model relates to the technical field of plastics cutting machines, in particular to a fast lifter framework for the pressure roll used in the bar cutter or cut-off tool. The utility model comprises a pressure roll, the two ends of which are provided with an adjusting board of the pressure roll respectively. The adjusting board of the pressure roll is inclined, and the lower part of the tilted end is provided with an eccentric block arranged on a shaft, while the upper part of the tilted end is provided with an adjusting device, the lower part of which contacts with the tilted end of the adjusting board of the pressure roll. By using the utility model, the fast promotion of the pressure roll can be realized, and the pressing force of the pressure roll and the parallelism of the pressure roll and the roll cylinder can be adjusted through a hand wheel, and the adjustment is simple and convenient.

Description

A kind of nip rolls fast lifting mechanism that is applied to slitting, cutting machine

Technical field:

The utility model relates to slitting, cutting machine technical field, refers in particular to a kind of nip rolls fast lifting mechanism that is applied to slitting, cutting machine.

Background technology:

At present, in China's plastic cement machining industry, slitting or cutting machine are in the feeding process, cut in order to make rubber plate enter into the knife rest below smoothly, can be provided with a nip rolls in knife rest the place ahead, very important between nip rolls and the rubber plate apart from size, distance is big, and nip rolls has just lost effect, the phenomenon that will occur getting stuck that distance is little, but in order to guarantee the steady of feeding, distance between nip rolls and the rubber plate is provided with smallerly, occurs the phenomenon that gets stuck sometimes, and the nip rolls lifting of traditional slitting or cutting machine is to realize by the handwheel that rotates the nip rolls two ends, this method is painstaking, and rising or falling speed is slow.In case occur getting stuck, operating personnel are always in a rush, and are with a face streaming with sweatly busy, operates unskilledly, owing to stuck for a long time, also can cause damage to the electrical equipment of machine.

The utility model content:

The purpose of this utility model is exactly to provide a kind of nip rolls fast lifting mechanism that is applied to slitting, cutting machine at the weak point of prior art existence.

To achieve these goals, the technical solution adopted in the utility model is: it comprises a nip rolls, the nip rolls two ends are connected with the nip rolls adjustable plate respectively, the nip rolls adjustable plate tilts to place, the bottom of perk one end is provided with an eccentric block, eccentric block is installed on one, and the top of perk one end is provided with adjusting device, the perk end in contact of the bottom of adjusting device and nip rolls adjustable plate.

Adjusting device comprises handwheel, roll cover, locknut, pressure roller adjusting rod, the spring seat of honour, roller seat, pressure roller is regulated tube, spring and spring lower seat, pressure roller is regulated the tube lower end and is had gap slot, roller seat and pressure roller are regulated the tube weldering and are one, pressure roller is regulated in the tube and is placed with the spring seat of honour, spring, spring lower seat successively, the end of thread of pressure roller adjusting rod connects with handwheel after connecting locknut, pressure roller adjusting rod lower end is regulated the tube upper surface with pressure roller and is contacted, and roll cover is regulated the tube upper end by being threaded with pressure roller.

After adopting said structure, when occurring getting stuck, as long as rotate eccentric block, eccentric block is jack-up pressure roller adjustable plate rapidly, thereby nip rolls is separated rapidly with following sheet material, and the inside extrusion spring of spring lower seat that contact with the pressure roller adjustable plate this moment makes the spring contraction; Size according to thrust is rotated handwheel, make nip rolls obtain the required thrust and the depth of parallelism of lower roller, after adjustment finishes, locknut is locked, prevent that handwheel is loosening or artificially rotate handwheel, and cause the nip rolls thrust to diminish or the depth of parallelism changes, so utilize the utility model can realize the fast lifting of nip rolls, also can regulate the thrust of nip rolls and the depth of parallelism of nip rolls and roller, regulate simple, convenient by handwheel.

Description of drawings:

Fig. 1 is the structural representation of adjusting device of the present utility model;

Fig. 2 is the STRUCTURE DECOMPOSITION figure of adjusting device of the present utility model;

Fig. 3 is the structural representation that the utility model is applied to stock-cutter.

The specific embodiment:

See shown in Fig. 1,2,3, the utility model comprises a nip rolls 1, nip rolls 1 two ends are connected with nip rolls adjustable plate 2 respectively, nip rolls adjustable plate 2 tilts to place, the bottom of perk one end is provided with an eccentric block 3, eccentric block 3 is installed on one 4, and the top of perk one end is provided with adjusting device 5, the perk end in contact of the bottom of adjusting device 5 and nip rolls adjustable plate 2.

Adjusting device 5 comprises handwheel 51, roll cover 52, locknut 53, pressure roller adjusting rod 54, the spring seat of honour 55, roller seat 56, pressure roller is regulated tube 57, spring 58 and spring lower seat 59, pressure roller is regulated tube 57 lower ends and is had gap slot 6, roller seat 56 is regulated tube 57 welderings with pressure roller and is one, pressure roller is regulated in the tube 57 and is placed with the spring seat of honour 55 successively, spring 58, spring lower seat 59, the end of thread of pressure roller adjusting rod 54 connects locknut 53 backs and connects with handwheel 51, pressure roller adjusting rod 54 lower ends are regulated tube 57 upper surfaces with pressure roller and are contacted, and roll cover 52 is regulated tube 57 upper ends by being threaded with pressure roller.

Operation principle a: end of pressure roller adjustable plate 2 is fixed on the side plate of frame 10 by axle 11 activities, pressure roller adjustable plate 2 tilts to place, the bottom of perk one end is provided with an eccentric block 3, the top of perk one end is provided with adjusting device 5, on frame 10 another side plates pressure roller adjustable plate 2 is installed too, when occurring getting stuck, as long as rotate eccentric block 3, eccentric block 3 is jack-up pressure roller adjustable plate 2 rapidly, thereby nip rolls 1 is separated rapidly with following sheet material, the spring lower seat 59 inside extrusion springs 58 that contact with pressure roller adjustable plate 2 this moment shrink spring 58; When the thrust of needs adjusting nip rolls 1 and the depth of parallelism of nip rolls 1 and lower roller, size according to thrust is rotated handwheel 51, spring 14 exerts pressure for nip rolls 1 by the spring lower seat 59 of lower end, adjusting by left and right handwheel 51, can guarantee that nip rolls 1 obtains the required thrust and the depth of parallelism, after adjustment finishes, with locknut 53 lockings, prevent that handwheel 51 is loosening or artificially rotate handwheel 51, and cause nip rolls 1 thrust to diminish or the depth of parallelism changes.

Certainly, the embodiment of the above, it is preferred embodiments of the present utility model, be not to limit the utility model practical range, so all equivalences of doing according to the described structure of the utility model claim, feature and principle change or modify, and are included in the utility model claim.
