[0025] The first positioning and fixing claw 8 includes a first hydraulic rod connecting block 15, a first claw rod 16 and a first clamping claw head 17. A first protrusion 18 is provided on the side of the first claw rod 16 close to the first hydraulic rod connecting block 15. A first groove 19 adapted to the first protrusion 18 is provided on one side of the first hydraulic rod connecting block 15. The first hydraulic rod connecting block 15 is fixed to the first claw rod 16 by bolts. The first clamping claw head 17 is crescent-shaped, which is convenient for positioning and clamping round-like plastic packaging products.

[0026] The second positioning and fixing claw 9 includes a second hydraulic rod connecting block 20, a second claw rod 21 and a second clamping claw head 22. A second protrusion 23 is provided at one end of the second claw rod 21 close to the second hydraulic rod connecting block 20. A second groove 24 adapted to the second protrusion 23 is provided on one side of the second hydraulic rod connecting block 20. The second hydraulic rod connecting block 20 and the second claw rod 21 are fixed by bolts. The second clamping claw head 22 is cylindrical. Several groups of first positioning and fixing claws 8 and several groups of second positioning and fixing claws 9 are arranged alternately, so that the first positioning and fixing claws 5 and the second positioning and fixing claws 6 can cooperate with each other.

[0027] A fifth hydraulic rod 25 is arranged in the slide groove formed in the upper clamping block 13 , and a pressing block 26 is arranged at the end of the fifth hydraulic rod 25 , so as to position and clamp the plastic packaging products with smaller sizes.

[0028] Push rings 27 are arranged on both sides of the slidable base 10, a slider 28 is arranged below the slidable base 10, and a slide groove adapted to the slider 28 is opened on the inner side of the base 1, which is more convenient for positioning and clamping plastic packaging products of different lengths.

[0029] A drawer box 29 is provided below the base 1 near the second clamping structure 4. A pull-out box 29 is provided on one side. Holes are provided on the contact surface between the drawer box 29 and the base 1 to facilitate centralized storage of waste generated during processing.

[0030] A sixth hydraulic rod 30 is provided between the base 1 and the support body 2 , and a shovel block 31 is provided on the sixth hydraulic rod 30 , so as to facilitate pushing the waste materials scattered on the base into the draw box 29 .

[0031] The surfaces of the first clamping claw 17, the second clamping claw 22, the upper clamping block 13, the lower clamping block 12 and the pressing block 26 are all provided with anti-skid rubber pads 32, which can not only prevent skidding but also protect the surface of the plastic packaging product being positioned and clamped.

[0032] like Figure 1-Figure 6As shown, the principle of the positioning and clamping mechanism for plastic packaging products provided in this embodiment is as follows: when using this structure, the first clamping structure 3 and the second clamping structure 4 should be adjusted according to the size and length of the plastic packaging product to be positioned and fixed. First, the push ring 27 is pushed to move the second clamping structure 4 to the size position adapted to the plastic packaging product under the action of the slider 28. Then, according to the shape of the plastic packaging product, the first positioning and fixing claw 8 or the second positioning and fixing claw 9 can be selected, or the first positioning and fixing claw 8 and the second positioning and fixing claw 9 can cooperate with each other to position and fix one end. Then, the second clamping structure 4 can be adjusted to the same height as the first clamping structure 3 through the third hydraulic rod 11, and the other end of the plastic packaging product is positioned and fixed by the contraction of the fourth hydraulic rod 14 through the upper clamping block 13 and the lower clamping block 12;

[0033] The first positioning and fixing claw 8 is composed of a plurality of claws, each of which is controlled to be extended and retracted by the first hydraulic rod 6. The plurality of claws can be simultaneously retracted by the first hydraulic rod 6 so that the first clamping claw head 17 clamps and positions the plastic packaging product. When the plurality of claws are simultaneously retracted and expanded by the first hydraulic rod 6, the first clamping claw head 17 expands and positions the plastic packaging product. However, the plurality of claws can be retracted and retracted separately by the first hydraulic rod 6 to position and fix the plastic packaging product.

[0034] The second positioning and fixing claw 9 is also composed of a plurality of claws, each of which is controlled to be extended and retracted by the second hydraulic rod 7. The plurality of claws can be simultaneously retracted by the second hydraulic rod 7 so that the second clamping claw head 22 clamps and positions the plastic packaging product. The plurality of claws can be simultaneously retracted and expanded by the second hydraulic rod 7 so that the second clamping claw head 22 expands and positions the plastic packaging product. However, the plurality of claws can be retracted and retracted separately by the second hydraulic rod 7 so as to be positioned and fixed.

[0035] Then, the waste generated by the thinning process of the clamped and fixed plastic packaging product will fall on the base 1, and then the waste will be shoveled and pushed into the draw box 29 on the other side by the shovel block 31 connected by the sixth hydraulic rod 30 between the base 1 and the support body 2.

[0036] For example, certain words are used in the specification and claims to refer to specific components. Those skilled in the art should understand that hardware manufacturers may use different terms to refer to the same component. This specification and claims do not use differences in names as a way to distinguish components, but use differences in the functions of components as the criteria for distinction. For example, "including" mentioned throughout the specification and claims is an open term, so it should be interpreted as "including but not limited to". "Approximately" means that within an acceptable error range, those skilled in the art can solve technical problems within a certain error range and basically achieve technical effects.

[0037] It should be noted that the terms "include", "comprising" or any other variations thereof are intended to cover non-exclusive inclusion, so that a product or system including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such product or system. In the absence of more restrictions, the elements defined by the sentence "comprising a ..." do not exclude the existence of other identical elements in the product or system including the elements.

[0038] The above description shows and describes several preferred embodiments of the utility model, but as mentioned above, it should be understood that the utility model is not limited to the form disclosed herein, and should not be regarded as excluding other embodiments, but can be used in various other combinations, modifications and environments, and can be modified within the scope of the utility model concept described herein through the above teachings or the technology or knowledge of the relevant field. The changes and modifications made by those skilled in the art do not deviate from the spirit and scope of the utility model, and should be within the scope of protection of the claims attached to the utility model.
