Blow molding machine turning clip

Abstract

The present invention belongs to the blow molding machinery, and in particular relates to a folding clip used for the blow molding machinery, the folding clip includes an underframe, a power mechanism arranged on the underframe, a folding mechanism connected with the power mechanism, and a stretching mechanism, the folding mechanism comprises two pairs of arc-shaped symmetrical clamping arms and face-to-face folding clamping knives arranged on the clamping arms; every two of the arc-shaped symmetrical clamping arms are in gear connection and synchronously move; after the folding mechanism is folded face to face, a gap is left between every two of the arc-shaped symmetrical clamping arms; hydraulic contamination of raw materials can be avoided, the manufacturing cost is greatly reduced, the clamping force of the turning clip is increased, so that the folding can be quick and neat, the folding time is saved, the raw material cooling can be prevented, the product quality can be greatly improved, the product is easier to shape, the stretching width of a stretching shaft is increased, under the premise of no increasing of the manufacturing cost, the folding clip can be better used in the production of larger diameter plastic buckets or blow molding machines, enterprise cost can be saved, and benefits are brought.

Description

technical field [0001] The invention belongs to a blow molding machine, in particular to a clip for closing up on a blow molding machine. Background technique [0002] When the blow molding industry uses a blow molding machine for blow molding, it is necessary to use clips to close the plastic raw materials before blow molding; because blow molding should be performed when the plastic raw materials are at a certain temperature and have the best stretchability, Ensure the quality and uniformity of blow molding; this requires that the closing speed should be fast, rapid, and short and thorough; therefore, clamps with large closing force and rapid response are required; general enterprises use hydraulically driven straight arm reverse clamps , the clamping strength of this kind of flip clamp is small, the cost is expensive, and it is easy to pollute the raw materials; and when the plastic raw materials are closed tightly, the stretching width is limited by the clamping arm and ...

[0002] When the blow molding industry uses a blow molding machine for blow molding, it is necessary to use clips to close the plastic raw materials before blow molding; because blow molding should be performed when the plastic raw materials are at a certain temperature and have the best stretchability, Ensure the quality and uniformity of blow molding; this requires that the closing speed should be fast, rapid, and short and thorough; therefore, clamps with large closing force and rapid response are required; general enterprises use hydraulically driven straight arm reverse clamps , the clamping force of this kind of flip clamp is small, the cost is expensive, and it is easy to pollute the raw materials; and when the plastic raw materials are closed tightly, the stretching width is limited by the clamping arm and the outer baffle, and the stretching width is not enough, so it is not suitable for manufacturing. In the application of plastic barrels with large diameters, usually when it is necessary to clamp relatively large barrels for blow molding, it is necessary to replace the flip clamp with a larger stretching range
