[0002] Plastic bottles are mainly made of materials such as polyethylene or polypropylene and added with a variety of organic solvents. Plastic bottles widely use polyester, polyethylene and polypropylene as raw materials. After adding corresponding organic solvents, they are heated at high temperature and then blow molded, extruded or injection molded through plastic molds to form plastic containers. After processing, the plastic bottle needs to be aligned with the bottle mouth for corresponding plasticity to meet the needs of later use.

There is no need to disassemble the entire grinding and shaping head for replacement. Adjusting the grinding and shaping heads of different sizes in this way is simple and convenient, thereby improving the use effect of the shaping device. BRIEF DESCRIPTION OF THE DRAWINGS

[0040] See also Figure 1-Figure 5 A fixing plate 11 is installed on the back of the frame 1, and a second cylinder 12 is installed on the back of the fixing plate 11. The output end of the second cylinder 12 is installed with a mounting plate 13 through a piston rod. A motor 14 is installed on the mounting plate 13, and the output end of the motor 14 is connected to a connecting plate 15. When the second cylinder 12 is working, the piston rod can be extended and retracted, thereby driving the mounting plate 13 to move, and the mounting plate 13 drives the motor 14 to move.

[0041] Specifically, the adjustment component 9 includes a first grinding and shaping head 901 arranged on the outer surface of the connecting plate 15, and the outer wall of the first grinding and shaping head 901 is sleeved with a retaining ring 913, and the outer wall of the first grinding and shaping head 901 is sleeved with a second grinding and shaping head 902, and the outer wall of the second grinding and shaping head 902 is sleeved with a third grinding and shaping head 903, and the third grinding and shaping head 903 is provided with a second guide hole 906, and the second grinding and shaping head 902 is provided with a first guide hole 904.

[0042] Specifically, two first guide rods 905 and second guide rods 914 are respectively installed on the retaining ring 913, and cavities 907 are opened inside the first guide rod 905 and the second guide rod 914, and multiple slide rods 910 are fixed inside the cavity 907, and the outer wall of the slide rod 910 is sleeved with a movable plate 909, and a threaded shaft 908 is connected to the upper side of one side of the movable plate 909 through a bearing, and two limit columns 912 are also installed on one side of the movable plate 909, and the inner sides of the second grinding and shaping head 902 and the third grinding and shaping head 903 are fixed with a plurality of slide rods 910.

[0045] On the basis of the above-mentioned first embodiment, in order to improve the stability of the pressing seat 8 when it moves, it is necessary to guide the pressing seat 8, so the following structure is set.

[0046] See also Figure 1-Figure 3 , both sides of the top of the clamping seat 8 are installed with limit rods 7 that penetrate the fixing frame 4. When the clamping seat 8 moves, the limit rods 7 can be driven to move, so as to improve the stability of the clamping seat 8 when it moves.

[0047] The working principle of the utility model is as follows: first, the user can install the shaping device and connect the power supply, then put the plastic bottle on the bottle support platform 3, and transmit it through the conveyor belt 2. When it is transmitted to the bottom of the pressing seat 8, the conveying of the conveyor belt 2 is suspended. At this time, the first cylinder 5 works to extend the piston rod, thereby driving the pressing seat 8 to move downward. The pressing seat 8 moves downward to press the plastic bottle, and then the second cylinder 12 is started to extend the piston rod, thereby driving the installation plate 13 and the motor 14 to move, and driving the third grinding and shaping head 903 to move, and at the same time starting the motor 14, the motor 14 drives the third grinding and shaping head 903 to rotate, so as to shape the bottle mouth of the plastic bottle;

When the limiting column 912 moves out of the limiting hole 911, the second grinding and shaping head 902 and the third grinding and shaping head 903 can be pushed upward, so that the second grinding and shaping head 902 and the third grinding and shaping head 903 move and no longer block the first grinding and shaping head 901, and then the limiting column 912 above 2 is moved into the limiting hole 911 to limit the second grinding and shaping head 902 and the third grinding and shaping head 903. At this time, the first grinding and shaping head 901 can be used to shape and grind the bottle mouth with the smallest diameter. When the second grinding and shaping head 902 in the middle is used, it is only necessary to rotate the threaded shaft 908 on the second guide rod 914, and then move the third grinding and shaping head 903 so that it no longer blocks the second grinding and shaping head 902. In this way, grinding and shaping heads of different sizes can be used to shape bottle mouths of different diameters.
