Background

At present, chains are important parts of transverse stretching equipment of a BOPP production line, in the production of films, a PP object is cast into a thick sheet through a die, the thick sheet is stretched into a thin sheet with the width of about 600mm and the thickness of about 3mm by longitudinal stretching equipment, the thin sheet enters transverse stretching equipment, two sides of the thin sheet are clamped by two groups of chain clamps, the chain clamps are arranged on two chains to respectively travel along two preset tracks, the distance between the two tracks is widened from narrow to narrow, and finally the thin sheet is transversely stretched into the thin film with the width of about 4000mm and the thickness of about 0.02 mm. After the production line runs for a period of time, particularly under the condition of high temperature in spring and summer, carbon deposition is easily generated on the chain and chain clamp of TDO (transverse stretching section) by volatile matters of raw materials or other impurities in air, and the serious consequences of film breaking and film non-forming are easily caused, so that the production line needs to be stopped at irregular intervals to clean and maintain the chain. At present, the length of a chain in a transverse stretching device of a production line is about 350 meters, the chain is composed of thousands of chain blocks, the splitting work of the chain blocks is a project with huge workload, the traditional splitting work of the chain is completely carried out manually by operators, and a large amount of manpower and time are needed for completing the splitting work. Above-mentioned chain split work is not only consuming time hard, prolongs the down time of the horizontal tensile equipment of BOPP production line, can't guarantee the split quality of each part of chain moreover.

Disclosure of Invention

The invention provides a chain splitting device of transverse stretching equipment, which is time-saving and labor-saving and can greatly improve the chain dismounting quality and efficiency for solving the technical problems in the prior art.

The technical scheme adopted by the invention for solving the technical problems in the prior art is as follows:

horizontal tensile equipment's chain split device, its characterized in that: including workstation, upper guideway, lower guideway, chain split backup pad, actuating cylinder, hammering block and hydraulic pressure case, workstation bottom both ends fixed work platform supports, and the lower guideway of mutual symmetry is equipped with admittedly at the workstation up end, the last guide rail that is equipped with on the lower guideway, actuating cylinder is equipped with through the hydro-cylinder support on workstation up end one side, actuating cylinder's tailpiece of the piston rod portion is connected with the hammering block, hammering block and upper guideway adorn admittedly, be equipped with on the opposite side of workstation up end with lower guideway one end vertically chain split backup pad, the hydraulic pressure case passes through pipeline and actuating cylinder intercommunication.

The invention can also adopt the following technical scheme:

and a plurality of slots for inserting and fixing the pin shafts of the outer chain plates are formed in the upper parts of the chain splitting supporting plates.

The slots are arc-shaped slots matched with the fixed outer chain plate pin shafts.

The invention has the advantages and positive effects that: by adopting the technical scheme, when an operator splits the chain, a section of chain is placed on the outer side of the chain splitting support plate, the pin shaft on each chain block is inserted into the arc-shaped slot on the upper part of the chain splitting support plate, the head part of the pin shaft of each chain block needs to be kept protruding out of the chain splitting support plate, then the driving oil cylinder is started, the piston rod moves forwards horizontally, the anvil block and the upper guide rail are pushed to move forwards along the lower guide rail, the anvil block is pushed to push against the head part of the pin shaft of each chain block to continue to push forwards until the pin shaft pushes out the detachable outer chain plate and is separated from the detachable outer chain plate, and thus each chain block of the chain can be split, and the chain splitting work is further.

The device can realize that 2-3 operators can quickly finish the splitting work of the chain, thereby not only saving time and labor, but also advancing the starting time of the stretching equipment by 1-2 days and shortening the stopping time; in addition, the chain splitting quality and the yield of the stretched film product are improved. The chain splitting device is simple in structure, avoids damage to the chain block caused by manual force removal, and can reduce equipment failure rate and processing cost.
