1-3, in an embodiment of the present utility model, a clamping and turning mechanism for cutting a plastic suction product is used for matching with a flat cutting machine for implementing cutting; comprising the following steps: a mechanism frame 3, a turnover group 1 and a clamping group 2;

the mechanism frame 3 is arranged on the working part of the existing conveying module 4, the turnover group 1 is arranged on the mechanism frame 3, the clamping group 2 is arranged on the turnover part of the turnover group 1, and the turnover is realized by driving the clamping group 2;

in the processing process, the original product to be processed is placed on the clamping group 2, and then the overturning group 1 drives the clamping group 2 to overturn, so that the original product to be processed is sent into a flat cutting machine by the conveying module 4 in a state that the product is downward to realize cutting processing, and the product is separated from the plastic suction sheet.

Specific:

the flipping group 1 includes: a turning shaft 12 and a bearing housing 13 for mounting the turning shaft 12 on the mechanism frame 3;

the rear end of the turnover shaft 12 is provided with a group of rotary motor units 11 for driving the turnover shaft to rotate;

the front end of the turning shaft 12 extends in the direction of the existing cutting machine, and the clamping group 2 of the turning clamping mechanism is mounted on the front end position of the turning shaft 12.

The clamping group 2 includes: the bearing plate 25, the lower end of the bearing plate 25 is provided with a mounting bracket 28, the bearing plate 25 is fixedly mounted on the front end position of the turnover shaft 12 through the mounting bracket 28;

the four corner positions of the bearing plate 25 are respectively provided with a clamping cylinder 21 working upwards, the upper end of the bearing plate 25 is provided with a clamping plate 26, and the lower end of the clamping plate 26 is respectively connected and matched with the piston rods of the clamping cylinders 21;

the clamping plate 26 is provided with a avoiding through groove 27 for avoiding the finished product piece; when the device works, an original product to be processed is placed in the bearing plate 25, the clamping cylinder 21 drives the clamping plate 26 to press down to clamp the plastic sucking sheet which is the original product to be processed, and the product of the original product to be processed passes through the avoidance through groove 27 together with the cutting position;

the working principle of the turnover clamping mechanism is as follows:

before feeding: the front of the bearing plate 25 in the clamping group 2 faces upwards, and the clamping plate 26 is kept in an open state, and the material transferring manipulator waits for placing the original product to be processed on the bearing plate 25; then, the clamping cylinder 21 drives the clamping plate 26 to press downwards, and the carrying plate 25 is matched to clamp the raw product (plastic-absorbing sheet) to be processed, so that the whole clamping work is completed;

then, the turnover group 1 drives the bearing plate 25 to perform 180-degree turnover (as shown in the working state of fig. 3), then the conveying module 4 drives the clamping group 2 to enter an existing flat cutting machine, the flat cutting machine horizontally cuts along a cutting position, the product and the plastic sucking sheet are separated, and the fallen product is collected to complete cutting processing;

then, the conveying module 4 drives the clamping group 2 to withdraw from the slitting mill, the overturning group 1 drives the bearing plate 25 again to perform tilting operation of about 45 degrees, so that the bearing plate 25 forms a tilting working posture, the holding cylinder drives the clamping plate 26 to reset and open, so that the plastic-absorbing sheets on the bearing plate 25 naturally slide down (are collected), waste unloading operation is realized, and finally, the overturning group 1 and the conveying module 4 drive the bearing plate 25 to reset to a receiving state, and the material manipulator waits for loading and processing again; according to the reciprocating mode, automatic feeding, overturning and cutting of the plastic sucking product are achieved.

a group of lateral positioning plates 23 are arranged in each positioning groove; four groups of turnover motor groups 24 corresponding to the lateral positioning plates 23 are arranged at the lower end of the bearing plate 25;

after the material transferring manipulator places the original product to be processed on the bearing plate 25, the four groups of overturning motor groups 24 work simultaneously to drive the lateral positioning plates 23 to overturn to be perpendicular to the bearing plate 25 and contact with the side edges of the plastic sucking sheets at the same time, so that the plastic sucking sheets are pushed to the central position, and the four groups of lateral positioning plates 23 are used for realizing the four-way positioning of the original product to be processed, so that the original product to be processed is fixed on the central position of the bearing plate 25; avoiding offset; after the work is completed, the turnover motor drives the lateral positioning plate 23 to reset.

It is further noted that relational terms such as first and second, and the like are used solely to distinguish one entity or action from another entity or action without necessarily requiring or implying any actual such relationship or order between such entities or actions.
