Description

Spinneret plate clamp convenient to replace Technical Field The utility model belongs to the technical field of chemical fiber production, and particularly relates to a spinneret plate clamp convenient to replace. Background The spinneret plate is also called a spinning cap, the spinneret plate is used for converting a high polymer melt or solution in a viscous state into a trickle with a specific section shape through micropores, a coagulating medium such as air or coagulating bath is solidified to form a filament, a spinneret plate clamp is a tool for clamping the spinneret plate, but the traditional spinneret plate clamp usually depends on manual disassembly, a spanner and other tools are usually needed in the process, if the tool slips off and possibly damages the surface of the clamp or the edge of the spinneret plate, the operation steps are tedious and long, an operator needs to repeatedly adjust the tightness degree of each clamping block, the stress deflection or the abrasion of the clamping surface of the spinneret plate is extremely easy to be caused due to uneven force application, and the clamping surface is easy to gradually lose pretightening force due to material fatigue or stress relaxation under the condition of long-term vibration or temperature fluctuation of equipment, so that micro displacement is generated between the spinneret plate and the clamp, and the loosening phenomenon can directly cause uneven spinning titer, yarn breakage or forming defects. Disclosure of utility model The utility model aims at providing a spinneret plate clamp convenient to replace, which has the advantages of firmly and uniformly clamping and preventing loosening. The spinneret plate clamp convenient to replace comprises a moving plate, sliding sleeves are bolted to the top and the bottom of the moving plate, sliding rods are sleeved in the sliding sleeves in a sliding mode, fixed plates are bolted to two sides, far away from the middle, of the two sliding rods, clamping blocks are bolted to the sides, opposite to the fixed plates, of the moving plate, limiting grooves are bolted to the right side of the moving plate, limiting blocks are connected to the inner portions of the limiting grooves in a sliding mode, bolts are bolted to the right side of the limiting blocks, screws are connected to the inner threads of the bolts, back plates are bolted to the right side of the sliding rods, and locking mechanisms are arranged on the left side of the surfaces of the sliding rods. According to the technical scheme, the screw rod rotates to drive the threaded sleeve to move backwards, the threaded sleeve moves to drive the limiting block to move along the path inside the limiting groove, the limiting block and the limiting groove are inclined planes, the limiting block moves backwards to uniformly extrude the limiting groove, the limiting groove is extruded to drive the moving plate to move leftwards, the sliding sleeve limits the movement of the moving plate, the moving plate moves to drive the clamping block to clamp the spinneret plate, the clamping block can move centripetally by rotating the screw rod, the clamping block can be uniformly forced to clamp the spinneret plate, stable stress and excellent centering are ensured, and when the spinneret plate needs to be replaced, the clamping block can be synchronously retracted and separated from the edge of the spinneret plate only by rotating the screw rod in the opposite direction, so that the operation process is visual and simple. The locking mechanism further comprises a fixed block, the fixed block is fixedly sleeved on the left side of the surface of the sliding rod, the front face of the fixed block is bolted with a bracket, the right side of the bracket is bolted with a spring, the right side of the spring is bolted with a fixed sleeve, the front face of the sliding sleeve is bolted with a fixed column, and the surface of the fixed column is sleeved with the inside of the fixed sleeve. According to the technical scheme, the locking mechanism is arranged, the fixing sleeve is held and pulled, the fixing sleeve drives the spring to stretch, the fixing sleeve is sleeved into the fixing column, the spring is contracted and tensioned, the clamping block can be prevented from loosening, after the clamping block finishes clamping the spinneret plate, the clamping block can be locked, the risk of loosening of the clamping caused by equipment vibration or external force impact is thoroughly eliminated, the high-precision alignment of the contact surface of the spinneret plate and the clamp is kept, no displacement or deflection is ensured in the processing process, the design of frequent manual re-tightening is not needed, the operation intervention is obviously reduced, the stability of continuous production is improved, and the problems of damage to the spinneret plate or fluctuation of spinning quality caused by loosening are reduced.
