Automatic double-rail film raising device

Abstract

The invention relates to an automatic double-rail film raising device, which comprises a rack and a film rolling rod. Lifting guide rails are arranged on the rack; the film rolling rod is arranged on the lifting guide rails; and the film rolling rod and the lifting guide rails are in sliding fit. Each guide rail comprises a chain driven by a motor; hanging wheels are arranged on the top ends of the chain; and the chain surrounds the hanging wheels to form a lifting closed loop. The two guide rails are arranged on two ends of the film rolling rod and are connected with the film rolling rod in an assembling way. Film rolling rod adjusting devices capable of adjusting the position of the film rolling rod are arranged on the guide rails, and comprise placement slots. The automatic double-rail film raising device provided by the invention adopts a structure with the two guide rails on the left side and the right side so as to achieve the aim that the single-side torque is avoided when a film rolling action force is acted on the guide rails since the two guide rails are distributed on the two sides, so that the requirement can be met without the need for a heavy-duty linear guide rail; and with the design of the guide rails on the two sides, the vertical height of slide blocks on the two sides can be adjusted separately, so that the two sides can have a better parallelism degree.

Description

Technical field: [0001] The invention relates to a laminating machine, which is mainly used in the printing industry. Background technique: [0002] The current film hanging device mainly includes a film loading trolley and a hoist. The film loading trolley needs to be loaded with a film roll device trolley and then transported to the film release shaft through the trolley. The disadvantage is that the rollers of the trolley are relatively small and the film hanging plate only It can be a unilateral structure, causing the cart to vibrate easily due to too small rollers during the pushing process, and the unilateral structure makes it easy to overturn. And the trolley adopts manual lifting film roll, which is slow and laborious. When the hoist is in use, the membrane needs to be hoisted by ropes. During the membrane lifting process, due to the flexibility of the ropes, the membrane roll is easy to shake when hoisting, causing potential safety hazards. In order to solve the ...

The film loading trolley needs to be loaded with a film roll device trolley and then transported to the film release shaft through the trolley. The disadvantage is that the rollers of the trolley are relatively small and the film hanging plate only It can be a unilateral structure, causing the cart to vibrate easily due to too small rollers during the pushing process, and the unilateral structure makes it easy to roll over

And the trolley adopts manual lifting film roll, which is slower and more laborious

When the hoist is in use, the membrane needs to be hoisted by a rope. During the membrane lifting process, due to the flexibility of the rope, the membrane roll is easy to shake when hoisting, causing a safety hazard.
