Description

Cloth discharging mechanism of printing machine

Technical Field

The utility model relates to a cloth discharging mechanism of calico printing machine belongs to calico printing machine technical field.

Background

The calico printing machine need carry out drying process after accomplishing cloth stamp, for the convenience ventilates the speed of accelerating the drying to the cloth, it is very high to do the frame of calico printing machine usually, set up drive roll group at the frame top, the cloth carries the whereabouts from between the drive roll group, compress tightly the transport to the cloth because of needs, two drive rolls of drive roll group are nearly tangent setting, the clearance between two drive rolls is minimum, and the cloth can appear the fold in data send process and the condition of knoing, and fold and the department of knoing are because of being thicker when the clearance through drive roll group, easily the card dies wherein, make drive roll group normal drive, because of its position that sets up is very high, need the workman to ascend a height and roll out it, not only it is inconvenient consuming time, still there is the potential safety hazard that the workman fell.

Disclosure of Invention

The utility model aims to solve the technical problem that a cloth discharging mechanism of calico printing machine is provided, its simple structure, when the cloth appears the dead condition of card through the drive roll group, can be convenient roll out it, can solve the not enough of prior art.

The technical scheme of the utility model is that: the utility model provides a cloth discharging mechanism of calico printing machine, is including setting up in the drive roller and the driven roll that are used for the cloth conveying at the frame top, including pushing away compression roller, drive arrangement, articulated in the frame have a swing arm, and the roller that bulldozes is connected with swing arm and drive arrangement respectively, and drive arrangement pushes away to bulldozing the roller and promotes and fix a position and make it be connected with the driven roll cooperation. The driving roller rotates to convey the cloth and drives the driven roller to rotate, the pushing and pressing roller is separated from the driven roller in a positioning state during normal conveying, and when the cloth is clamped between the driving roller and the driven roller and cannot normally rotate, the driving device drives the pushing and pressing roller to rotate around the swing arm to push the driven roller to rotate so as to rigidly rotate the cloth.

Further drive arrangement includes fixed plate, the linking arm of rigid coupling in the frame and set up the open slot, linking arm one end is rotated with the bulldozing roller and is connected, and the other end articulates there is the pull rod, the pull rod is connected with the open slot cooperation and is provided with the stopper that keeps off with the fixed plate cooperation on the pull rod. The pull rod penetrates through the open slot, the limiting block abuts against the back of the fixing plate, the pushing and pressing roller is not in contact with the driven roller and is in a locating state, the pull rod is pulled out of the open slot, the limiting block does not abut against the fixing plate, the pushing and pressing roller is driven by the pushing and pressing pull rod to rotate along the swing arm to be in contact with the driven roller and push the driven roller to rotate, and when the cloth is clamped in the transmission roller set, the cloth is rotated out.

And a pull ring is arranged at the end of the pull rod, which is far away from the connecting arm. The pull rod is convenient for the worker to push and pull, and is not easy to slip.

Furthermore, the open slot is V-shaped, and the opening of the open slot is larger than the inside of the open slot. The pull rod is convenient to move in the groove along the notch.

And an elastic rubber layer is further arranged on the driven roller. The driven roller has certain elastic deformation capacity, so that the cloth is convenient to rotate out when the cloth is stuck, and is in soft contact with the pushing and pressing roller to prevent the cloth from being scratched, and the cloth is not easy to damage when being pushed and pressed.

And a polytetrafluoroethylene layer is further arranged outside the elastic rubber layer. The friction coefficient is small, and the cloth can be better conveyed.

The driving device is further an electric cylinder, and the electric cylinder is connected with the control device through a circuit. When the cloth is stuck, the electric cylinder is controlled by the operation control device to drive the pushing roller to rotate and contact and push the driven roller, so that the operation is simple and convenient.

To sum up, the utility model provides a simple structure, when the cloth carries the card to die between the drive roll group, can conveniently be with the play cloth mechanism of its roll-out.

Detailed Description

The embodiment of the utility model provides a: as shown in fig. 1 to 2, a cloth discharging mechanism of a printing machine comprises a driving roller 2 and a driven roller 3 which are arranged at the top of a frame 1 and used for conveying cloth, a pushing roller 4 and a driving device, wherein two sides of the frame 1 are respectively hinged with a swing arm 5, the pushing roller 4 is respectively connected with the swing arm 5 and the driving device, and the driving device pushes and positions the pushing roller 4 to enable the pushing roller to be connected with the driven roller 3 in a matching manner. The driving roller 2 rotates to convey the cloth and drives the driven roller 3 to rotate, the pushing and pressing roller 4 is separated from the driven roller 3 in a positioning state during normal conveying, and when the cloth is clamped in the driving roller 2 and the driven roller 3 and cannot normally rotate, the driving device drives the pushing and pressing roller 4 to rotate around the swing arm 5 to push the driven roller 3 to rotate so as to rigidly rotate the cloth.

The preferential drive arrangement of this embodiment includes that the rigid coupling is in frame 1 and set up fixed plate 6, the linking arm 8 of open slot 7, and 8 one ends of linking arm are connected with 4 rotations that bulldoze the roller, and the other end articulates there is pull rod 9, and pull rod 9 is connected with the cooperation of open slot 7 and is provided with the stopper 11 that keeps off with the fixed plate 6 cooperation on the pull rod 9. The pull rod 9 penetrates through the open slot 7, the limiting block 11 is abutted to the back of the fixing plate 6, the pushing and pressing roller 4 is not contacted with the driven roller 3 and is in a locating state, as shown in fig. 3, the pull rod 9 is pulled out from the open slot 7, the limiting block 11 is not abutted to the fixing plate 6, the pushing and pressing roller 4 is driven by the pushing and pressing pull rod 9 to rotate along the swinging arm 5 to be contacted with the driven roller 3 and to be pushed to rotate according to the original rotating direction, and when the cloth is clamped in the transmission roller set, the cloth is rotated out.
