Description

Dull and stereotyped membrane equipment of adjustable cutter rise

Technical Field

The utility model relates to a production facility especially relates to a dull and stereotyped membrane equipment of adjustable cutter rise.

Background

The flat membrane equipment generally runs uninterruptedly, when the flat membrane in the running process of the equipment runs out and needs to be replaced by a new material, because the stub bar of the new material is thicker than the rear section, the scraper needs to be lifted to place a new stub bar when the new material is replaced. For cleaning of the equipment, the scraper needs to be lifted a great distance to free up sufficient space, and thus the stroke of the cylinder for lifting the scraper may be large. However, the scraper can be lifted a large distance by the large-stroke cylinder when a new material is replaced, dye can flow out of a gap generated by the lifting of the scraper in the lifting and lowering processes of the scraper to cause waste, and the longer the lifting time of the scraper is, the more dye is wasted; after the scraper is lifted and placed into a new stub bar, new materials can be conveyed into the equipment, but the scraper does not descend in place at the moment, and the printed and dyed cloth is waste materials, so that the longer the time required for the scraper to descend in place is, the longer the length of the new materials conveyed into the equipment is, and the more waste is.

Disclosure of Invention

The utility model aims to solve the technical problem that a can restrict the scraper and promote the stop device that highly never reduces scraper action required time when changing cloth is provided.

The utility model provides a technical scheme that above-mentioned technical problem adopted does: the utility model provides a promotion stop device of dull and stereotyped membrane equipment of adjustable cutter rise, includes the frame, it is connected with connecting block and couple to rotate in the frame, the piston rod of fixedly connected with cylinder on the connecting block, fixedly connected with stopper on the cylinder body, be provided with the spacing groove on the stopper, the gib head position of couple is in the spacing inslot and is separated by the certain distance with the tank bottom of spacing groove, be connected with the scraper on the cylinder body.

A first groove penetrating through the outer side surface of the lower end of the connecting block 2 is arranged, the side surface of the first groove is perpendicular to the connecting hole, the first groove is located in the middle of the lower end of the connecting block 2, and the supporting column extends into the first groove; therefore, the downward force of the connecting block 2 is respectively applied to the rotating shafts 7 on two sides of the supporting column, and the supporting column is positioned in the middle of the two stressed areas. The connecting block 2 is axially limited at the axial position of the rotating shaft 7 through a shaft clamp spring sleeved on the limiting step and the clamp spring groove. The piston rod of the cylinder is rotatably connected with the rack 1 through the connecting block 2, and the rack 1 is provided with a supporting point of the cylinder to limit the rotating range of the cylinder. The connecting block 2 can also be fixedly connected with the frame 1 through screws. The rotary connection between the connecting block 2 and the rotating shaft 7 is shown in figure 3.

The upper end of the connecting block 2 is fixedly connected with a piston rod 41 of the air cylinder 4 through threads, and in order to ensure fastening, a nut is screwed on the piston rod 41 of the air cylinder 4 and is fastened through the nut and the threads on the connecting block 2.

On the terminal surface under the casing of cylinder 4, promptly the terminal surface that piston rod 41 stretches out, through screw hole fixedly connected with mounting panel 42 on this terminal surface, fixedly connected with stopper 6 is gone up towards the terminal surface of frame 1 to mounting panel 42, be provided with spacing groove 61 on the stopper 6, stopper 6 suits with couple 5 with the position of spacing groove 61. The hook head part 51 of the hook 5 extends into the limiting groove 61, the lower end face of the hook head part 51 is a plane, and the outer end of the hook head part slightly protrudes downwards. The lower end surface of the hook head 51 is spaced from the lower end surface of the stopper groove 61 by a distance, which is an operation distance of the cylinder 4.

An adjusting screw 10 is screwed on the lower end face of the limiting block 6 through threads, and the threaded end of the adjusting screw 10 extends into the limiting groove 61. The adjusting screw 10 is used for finely adjusting the action distance of the cylinder 4 so as to make up for processing and mounting errors of each limiting component and finely adjust according to actual production requirements. And a fixing nut is screwed on the thread section of the adjusting screw 10, and the adjusting screw 10 is screwed on the limiting block 6 by the fixing nut. The connection of the hook 5, the limiting block 6 and the adjusting screw 10 is shown in fig. 3 and 4.

The end face, far away from the piston rod 41, of the shell of the cylinder 4 is fixedly connected with a transverse plate through a screw, and the transverse plate is fixedly connected with a vertical plate. The side face, facing the rack 1, of the vertical plate is provided with a through hole, one end of a connecting rod is inserted into the through hole, the other end of the connecting rod is fixedly connected with the upper end of a pulling plate through a screw, and the lower end of the pulling plate is fixedly connected with a scraper frame through a screw.

The hook head part 51 is connected with a link mechanism 8, and the link mechanism 8 drives the hook head part 51 of the hook 5 to leave the limiting groove 61. The link mechanism 8 is positioned on the side surface of the frame 1 near the side edge. The link mechanism 8 comprises a lower end of a first rod 81 rotatably connected with the frame 1, one end of a second rod 82 is rotatably connected with the upper end of the first rod 81, and the other end of the second rod 82 is rotatably connected with the hook 5. The first rod 81, the second rod 82 and the body of the hook 5 form a four-bar mechanism. When the first rod 81 rotates, the first rod 81 drives the second rod 82 to move in a direction away from the rack 1, and the second rod 82 drives the hook 5 to rotate in a direction away from the limiting block 6, so that the hook head 51 of the hook 5 leaves the limiting groove 61. When the hook head 51 leaves the limiting groove 61, the cylinder 4 can move in a full stroke to clean and change the liquid of the equipment. The linkage 8 is shown in figure 2.

In order to facilitate the rotation of the first rod 81, a rotating rod 9 is fixedly connected to the first rod 81, and a handle 3 is fixedly connected to the rotating rod 9.
