[0015] Compared with the prior art, the beneficial effects of this utility model are: the cutting device for plastic blister trays that is easy to position not only enables quick positioning of the workpiece and effective limitation of the workpiece, but also enables automatic pushing of the workpiece for continuous cutting.

[0016] (1) By setting up a cutting blade, mounting base, hydraulic cylinder, limit plate, fixing sleeve, spring, positioning pressure plate and connecting column, when cutting, the hydraulic cylinder inside the fixing frame is activated to push the mounting base down, the mounting base drives the cutting blade down, and at the same time the mounting base pushes the positioning pressure plate down through the fixing sleeve and spring so that the positioning pressure plate is attached to the top of the blister tray, which can press and position the blister tray.

The second servo motor is started to drive the two-way screw to rotate. The two-way screw drives the connecting plates at both ends to move through the threaded cylinder. The connecting plates then drive the positioning baffle at the bottom to move, so that the positioning baffles at both ends fit against the two ends of the workpiece and can effectively limit its position. The limiting shaft at one end of the fixed plate fits against the inside of the limiting sleeve and can limit the positioning baffle through the connecting plate. The positioning baffle can prevent the workpiece from shaking, thus achieving effective workpiece limiting.

[0018] (3) By setting up a slide, push plate, connecting piece, threaded sleeve, threaded shaft, cavity and first servo motor, the workpiece is attached to one side of the push plate during cutting. The first servo motor inside the base is started. The first servo motor drives the threaded sleeve to move to one side through the threaded shaft. The threaded sleeve then drives the push plate at the top to move to one side through the connecting piece. The push plate then pushes the workpiece to one side and sends it into the interior of the fixed frame for cutting. This realizes that the workpiece can be automatically pushed to move and continuously cut. Attached Figure Description

[0028] Specifically, such as Figure 1 and Figure 2 As shown, during cutting, the hydraulic cylinder 5 inside the fixed frame 2 is activated to push the mounting base 4 down. The mounting base 4 drives the cutting blade 3 down. At the same time, the mounting base 4 pushes the positioning plate 19 down through the fixed sleeve 7 and the spring 18, so that the positioning plate 19 fits against the top of the blister tray, which can press and position the blister tray. Then, the mounting base 4 continues to push the cutting blade 3 down to cut the bottom of the blister tray, which realizes the ability to quickly position the workpiece.

[0029] Fixed plates 8 are fixedly connected to both ends of the left side of the fixed frame 2. A positioning baffle 10 is provided at one end of the fixed plate 8.

A limiting shaft 24 is movably connected to one end of the fixed plate 8. A second servo motor 25 is fixedly connected to the left side of the other end of the fixed plate 8.

[0030] The positioning baffle 10 is movably connected to the base 1, and the limiting shaft 24 is slidably connected to the limiting sleeve 21;

[0031] The threaded cylinder 22 is threadedly connected to the bidirectional lead screw 23, and the output end of the second servo motor 25 passes through the fixing plate 8 and is fixedly connected to the bidirectional lead screw 23.

[0032] Specifically, such as Figure 1 , Figure 3 and Figure 4 As shown, before cutting, the workpiece is placed on the top of the base 1. The second servo motor 25 is started to drive the bidirectional lead screw 23 to rotate. The bidirectional lead screw 23 drives the connecting plates 9 at both ends to move through the threaded cylinder 22.

The push plate 12 then pushes the workpiece to one side and sends it into the interior of the fixed frame 2 for cutting, thus realizing the ability to automatically push the workpiece to move for continuous cutting.

[0037] Working Principle: In use, before cutting, the workpiece is placed on the top of the base 1. The second servo motor 25 is started, driving the bidirectional lead screw 23 to rotate. The bidirectional lead screw 23 moves the connecting plates 9 at both ends through the threaded cylinder 22. The connecting plates 9 then move the positioning baffles 10 at the bottom, causing the positioning baffles 10 to fit against the two ends of the workpiece, effectively limiting its movement. The limiting shaft 24 at one end of the fixing plate 8 fits against the inside of the limiting sleeve 21, limiting the positioning baffles 10 through the connecting plates 9.

During cutting, the hydraulic cylinder 5 inside the fixed frame 2 is activated to push the mounting seat 4 down. The mounting seat 4 drives the cutting blade 3 down. At the same time, the mounting seat 4 pushes the positioning pressure plate 19 down through the fixed sleeve 7 and the spring 18 so that the positioning pressure plate 19 fits against the top of the blister tray, which can press and position the blister tray. After that, the mounting seat 4 continues to push the cutting blade 3 down to cut the bottom of the blister tray.
