Abstract

The utility model provides a cylinder-pressurized four-roller traction machine used for traction rubber belts of PVC (Polyvinyl Chloride) and PVG flame retardant conveying belt production lines. The cylinder-pressurized four-roller traction machine comprises a frame, a driven roller 1, a cylinder, an impression roller, a driven roller 2, a drive roller, a gear and a rubber belt, wherein the cylinder is arranged on the frame, the impression roller is arranged on the lower end part of the cylinder, the driven roller 1 is arranged on the left end part of the impression roller and the upper end part of the drive roller, the driven roller 2 is arranged on the lower end part of the impression roller, the drive roller is arranged on the lower end part of the driven roller 1, the gear is arranged on the outer end part of the rubber belt, and the rubber belt is arranged on the driven roller 1, the driven roller 2 and the drive roller. The cylinder-pressurized four-roller traction machine, provided by the utility model, has the advantages of simple structure, flexibility, durability, convenience for use and the like.

Description

A kind of cylinder adding pressure type four roller hauling machines

Technical field

The utility model relates to PVC, PVG fire retarding conveying band production line traction rubber strip manufacturing technology field, particularly a kind of cylinder adding pressure type four roller hauling machines.

Background technology

Traditional hauling machine is not through the cylinder pressurization, but on backer roll, adorns a screw rod and handwheel, drives the screw rod rotation through rotating handwheel, plays the effect that backer roll moves up and down.Backer roll can be pushed down driven roll two with certain pressure during duty, and is if use manual adjustments, cumbersome; And after in case screw rod forwards the position to and push down, can not adjust automatically, all get manual rotary screw when at every turn needing to regulate; So just brought troublesome poeration, shortcoming such as efficient is low.

The utility model content

In order to overcome the technical problem that exists in the prior art, the utility model provides following technical scheme:

A kind of cylinder adding pressure type four roller hauling machines; Be used for PVC, PVG fire retarding conveying band production line traction rubber strip, said cylinder adding pressure type four roller hauling machines comprise frame, driven roll one, cylinder, backer roll, driven roll two, drive roll, gear, rubber strip, and said cylinder is installed on the frame; Said backer roll is installed on the cylinder lower end part; Said driven roll one is installed on backer roll left end position and position, drive roll upper end, and said driven roll two is installed on the backer roll lower end part, and said drive roll is installed on position, driven roll one bottom; Said gear is installed on position, rubber strip outer end, and said rubber strip is installed on driven roll one, driven roll two, the drive roll.

Preferably, drive drive roll by motor reducer and rotate, and play rotation one by one through the gear driven driven roll, cylinder pressurizes downwards simultaneously, pushes down driven roll two to backer roll downwards, makes whole hauling machine drive rubber strip and rotates.

The beneficial effect that the utility model brought is: because design has adopted the four roller hauling machines operation of cylinder pressurization just more convenient, only need mix up air pressure during duty, open valve and just can make backer roll push down driven roll two with certain pressure; And cylinder has retractility; When running into the rubber strip thickening, can pass through automatically, very convenient; Therefore the utlity model has advantages such as flexible, durable, easy to use.

The specific embodiment

Following facing combines accompanying drawing that the preferred embodiment of the utility model is done to set forth in detail, thereby so that advantage of the utility model and characteristic can be easier to it will be appreciated by those skilled in the art that the protection domain of the utility model made more explicit defining.

As shown in Figure 1; A kind of cylinder adding pressure type four roller hauling machines; Be used for PVC, PVG fire retarding conveying band production line traction rubber strip, said cylinder adding pressure type four roller hauling machines comprise frame 1, driven roll 1, cylinder 3, backer roll 4, driven roll 25, drive roll 6, gear 7, rubber strip 8, and said cylinder 3 is installed on the frame 1; Said backer roll 4 is installed on cylinder 3 lower end parts; Said driven roll 1 is installed on backer roll 4 left end positions and position, drive roll 6 upper end, and said driven roll 25 is installed on backer roll 4 lower end parts, and said drive roll 6 is installed on driven roll one 2 lower end parts; Said gear 7 is installed on position, rubber strip 8 outer end, and said rubber strip 8 is installed on driven roll 1, driven roll 25, the drive roll 6.

When specifically working, drive drive roll 6 by motor reducer and rotate, and rotate together through gear 7 drive driven rolls 1, while cylinder 3 pressurizes downwards, pushes down driven roll 25 to backer roll 4 downwards, makes whole hauling machine drive rubber strip 8 and rotates.

The above; Be merely one of specific embodiment of the utility model; But the protection domain of the utility model is not limited thereto; Any those of ordinary skill in the art are in the technical scope that the utility model disclosed, and variation or the replacement that can expect without creative work all should be encompassed within the protection domain of the utility model.Therefore, the protection domain of the utility model should be as the criterion with the protection domain that claims were limited.
