Technical Field
The utility model relates to a mould membrane violently draw the machine field, especially relate to a mould membrane violently draw tail chain tensioning assembly.
Background
The plastic film transverse drawing machine is a drawing machine used for producing a bidirectional drawing film and comprises four steps of preheating, drawing, shaping and cold cutting. The main key parts are two groups of guide rails and transmission chains. The two groups of parallel guide rails form an expansion angle with the central line when the stretching section is expanded, the angle is related to the stretching speed, and the distance between the two guide rails after being expanded and then parallel is the width of a finished film, which depends on the required stretching multiple different from material to material.
In the operation process of the plastic film transverse drawing machine, the chain is loosened frequently, the chain needs to be detached for adjustment at the moment, the detaching process is complex, and the time and the labor are consumed.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a mould membrane violently draw tail chain tensioning assembly.
The utility model discloses an innovation point lies in the utility model discloses installing chain tensioning subassembly at moulding membrane violently drawing tail, can be through the elasticity of rotating lead screw control chain, convenient operation.
In order to realize the purpose of the utility model, the technical proposal of the utility model is that: a plastic film transverse drawing machine tail chain tensioning assembly comprises a support frame, wherein a sliding groove is formed in the top of the support frame, a sliding block which slides in the sliding groove is arranged on the sliding groove, a lead screw which is arranged in parallel with the sliding groove is arranged on the support frame, the lead screw is connected with the support frame through a bearing, a connecting block is arranged at the bottom of the sliding block, a threaded hole which is in threaded connection with the lead screw is formed in the connecting block, a rotating block is arranged on the sliding block, the rotating block is connected with the sliding block through a pin shaft and can rotate relative to the sliding block, a stretching block is arranged above the rotating block, a first protruding strip with a trapezoidal first section or an inverted trapezoidal first section is arranged on the top surface of the rotating block, a second protruding strip which is matched with the first groove or a second groove which is matched with the first protruding strip is arranged on; and the stretching block is provided with a guide rail connecting threaded hole.
Further, the top edge of the stretching block is provided with a ring of annular grooves. The annular groove is an oil collecting groove and is used for receiving oil leakage of the chain connected with the upper part and is convenient to clean.
Furthermore, a handle is arranged at one end of the screw rod. The handle conveniently rotates the lead screw to drive the slider to slide in the spout.
The utility model has the advantages that:
1. the utility model discloses having installed chain tensioning subassembly at moulding membrane violently drawing tail, can be through rotating the elasticity of lead screw control chain, convenient operation.
2. The utility model discloses be equipped with round annular groove at tensile piece top edge for accept the oil leak of the chain that upper portion is connected, be convenient for wash.
3. The utility model discloses well tensile piece can slide on rotatory piece, and the tensile piece that is used for fixed guide rail when the cold contraction that rises with heat of guide rail can slide on rotatory piece, for guide rail hot expansion cold contraction reserve space, avoids the guide rail to buckle.
