Problems solved by technology

Because the front, middle and back are connected together, this structure has the disadvantages of mutual restriction, cumbersome structure, large scale, unfavorable assembly, easy damage, and inconvenient maintenance.
[0003] Another lifting system of the continuous stretching vacuum packaging machine is that a cylinder directly drives the mold to lift up and down. This lifting method has a simple structure, but the inertial force is generated when the cylinder is running, and the noise is large, and there is no self-locking after the cylinder is extended. Regression occurs under various pressures

Embodiment Construction

[0014] Below in conjunction with accompanying drawing and embodiment, further elaborate the present invention. In the following detailed description, certain exemplary embodiments of the invention are described by way of illustration only. Needless to say, those skilled in the art would realize that the described embodiments can be modified in various different ways, all without departing from the spirit and scope of the present invention. Accordingly, the drawings and description are illustrative in nature and not intended to limit the scope of the claims.

[0015] Such as figure 1 and figure 2 As shown, the independent self-locking lifting device of the mold of the continuous stretching vacuum packaging machine is used on the forming mold or the sealing mold. Work independently. This embodiment includes a packaging machine wallboard 15, the opposite wallboards 15 are respectively equipped with guide grooves 2 arranged up and down, and guide blocks 3 are installed on th...

Abstract

The invention discloses an independent self-locking mould lifting device for a continuous-drawing vacuum packaging machine. The independent self-locking mould lifting device comprises wall plates of the packaging machine, guide blocks are mounted on guide grooves which are mounted on the wall plates, an upper frame is mounted on the guide blocks, two pairs of large bearing blocks are mounted on the wall plates, a large supporting shaft is mounted on each pair of large bearing blocks, a pair of rockers is fixedly mounted on each large supporting shaft, a connecting shaft is mounted at the upper end of each pair of rockers, a pair of lifting rollers are mounted on each connecting shaft, and a lower frame which hinges two pairs of rockers into a parallelogram swing truss is mounted between the connecting shafts. A down pulling roller is mounted at the lower end of an upper frame pulling block which is mounted on the upper frame, and a rocker driving device is mounted on one pair of rockers. Integral lifting of moulds is modified into independent self-locking lifting, so that lifting effect is improved, mechanical performance and efficiency are improved, and maintenance rate is lowered.

Description

technical field [0001] The invention relates to a continuous stretching vacuum packaging machine, in particular to a mold lifting system component of the continuous stretching vacuum packaging machine. Background technique [0002] The mold lifting system of the continuous stretching vacuum packaging machine is a mechanical device for the packaging machine to control the lifting of the mold. This type of lifting system in the prior art is driven by the lifting cylinder to lift the overall upper and lower shelves to move up and down, thereby driving the two installed on the upper shelf. The mold and the lower cutter move up and down. Because the front, middle and back are connected together, this structure has the disadvantages of mutual restriction, cumbersome structure, large scale, unfavorable assembly, easy damage, and inconvenient maintenance. [0003] Another lifting system of the continuous stretching vacuum packaging machine is that a cylinder directly drives the mol...
