Problems solved by technology

[0004] Limited by the process, the semi-finished plastic bottles produced by the existing automatic hollow blow molding machines usually have redundant negatives and uneven bottle mouths (see figure 1 ), so the semi-finished products in the storage area need to be taken out in the follow-up, and the operation of removing the bottom and cutting the bottle mouth is performed. However, in the prior art, the operation of removing the bottom and cutting the bottle mouth is performed manually by workers, and the workload is large. High labor intensity and low efficiency

Embodiment Construction

[0035] The present invention will be further described in detail below in conjunction with the drawings.

[0036] reference figure 1 with figure 2 , Is a rear-end processing device for a hollow blow molding machine disclosed in the present invention, which includes a bottom-cutting mechanism 2, a transfer mechanism 4, and a bottom-cutting mechanism for bottom-cutting the semi-finished plastic bottles 14 in the storage area. The plastic bottles 14 in the area are transferred to the transfer mechanism 3 on the transfer mechanism 4 and the bottle-cutting mechanism 5 connected to the end of the transfer mechanism 4.

[0037] reference figure 2 with image 3 The bottom-cutting mechanism 2 is installed in the hollow blow molding machine and located at the bottom of the storage area. The bottom-cutting mechanism 2 includes a bottom-cutting frame 21, a bottom-cutting knife 22 arranged at the bottom of the storage area, and a bottom-cutting knife 22 for driving the bottom-cutting knife 22 ...

Abstract

The invention relates to the field of blow molding equipment, in particular to a back end processing device for a hollow blow molding machine. An existing blow-molded plastic bottle needs manual bottom removal and manual mouth cutting, the labor intensity is high, and the efficiency is low. According to the scheme, the back end processing device comprises a bottom cutting mechanism for performingbottom cutting operation on a semi-finished product plastic bottle in a storage region, a conveying mechanism, a transfer mechanism for transferring the plastic bottle in the storage region to the conveying mechanism and a bottle mouth cutting mechanism connected to the tail end of the conveying mechanism. By the adoption of the scheme, automatic bottom removal operation and bottle mouth cutting operation can be carried out on the plastic bottle produced by the blow molding machine, so that the labor intensity of workers is lowered, and efficiency is improved.

Description

Technical field [0001] The invention relates to the field of blow molding equipment, in particular to a back-end processing device for a hollow blow molding machine. Background technique [0002] Blow moulding, also known as hollow blow moulding, is a rapidly developing plastic processing method. Tubular plastic parison obtained by extruding or injection molding thermoplastic resin through a die (see figure 1 ), while it is hot, the split mold moves to both sides of the parison and clamps the parison inside. After closing the mold, the split mold drives the parison to move below the nozzle. Compressed air is injected into the parison from the nozzle to make the plastic mold The blank is inflated and tightly attached to the inner wall of the mold, and after cooling and demolding, a hollow plastic semi-finished product is obtained. [0003] Usually in order to improve the processing efficiency, a clamping device is installed on the split mold, see figure 1 , The clamping device foll...
