[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.
[0027] The following is in conjunction with the appendix Figure 1 —6 provides further detailed information about this application.
[0028] This application discloses a die-cutting machine for processing double-layer insulated paper bowls. (Refer to...) Figure 1 - Figure 6 A die-cutting machine for processing double-layer insulated paper bowls includes a processing table 1, a side plate 2 fixed on the processing table 1, a mounting plate 3 rotatably mounted on the processing table 1, and multiple load plates 4 fixed on the outer wall of the mounting plate 3.
[0029] The bottom of the processing table 1 is equipped with a drive source that drives the mounting plate 3 to rotate. The structure of the drive source is the same as that of the prior art, and will not be described in detail here.
[0030] The loading plate 4 is shaped like an inverted "U". The top of the loading plate 4 is provided with a sliding groove 401. There are four sliding grooves 401, which are distributed in a rectangular shape. A U-shaped rod 5 is slidably fitted on two adjacent sliding grooves 401. The two ends of the top of the U-shaped rod 5 are fixed with positioning components 6. A fixing mechanism for positioning the U-shaped rod 5 is provided on the U-shaped rod 5.
[0031] The positioning component 6 is used to fix the cardboard placed on top of the carrier plate 4. Its composition and operation are the same as those of the existing technology, and will not be described in detail here.
[0032] A mounting frame 9 is mounted on the side plate 2 in a height-adjustable manner. A rotating shaft 10 is mounted on the mounting frame 9 via a bearing. A fixed seat 14 is fixed on the rotating shaft 10. A die-cutting blade 15 is fixed at the top and bottom of the fixed seat 14. The two die-cutting blades 15 are of different sizes. By rotating the two die-cutting blades 15, their positions can be changed to meet the needs of processing paper bowls of different sizes.
[0033] Reference Figure 5 and Figure 6 The mounting bracket 9 is shaped like an inverted "U". A circular hole is opened through one side of the mounting bracket 9. A rotating block 11 is fixed at one end of the rotating shaft 10 that passes through the circular hole. Limiting holes 1101 are opened at the top and bottom of the rotating block 11. A perforated plate 12 is fixed on the outer wall of the mounting bracket 9. A hand screw 13 is fitted in the hole of the perforated plate 12. The bottom end of the hand screw 13 is engaged with the limiting hole 1101.
[0034] Reference Figure 1 , Figure 2 and Figure 3 Positioning holes 402 are provided on both sides of the bottom of the loading plate 4, and there are several positioning holes 402.
[0035] Reference Figure 3 and Figure 4 The fixing mechanism includes a groove 501 formed on a U-shaped rod 5. A through hole 502 communicating with the groove 501 is formed on one side of the U-shaped rod 5. A spring 503 is fixed on one side of the inner wall of the groove 501. A slider 504 is slidably connected in the groove 501. One end of the spring 503 is fixedly connected to the slider 504. A positioning rod 505 is fixed on the end of the slider 504 away from the spring 503. One end of the positioning rod 505 passes through the through hole 502 and engages with the positioning hole 402. The slider 504 is T-shaped. A cover plate 506 covering the groove 501 is fixed on the U-shaped rod 5 by bolts. A rectangular groove is formed on the cover plate 506. One end of the slider 504 passes through the rectangular groove and slidably engages with the rectangular groove.
[0036] When the slider 504 is pulled, the positioning rod 505 disengages from the positioning hole 402 at the bottom of the carrier plate 4. At this time, the U-shaped rod 5 can slide freely in the sliding groove 401. When the U-shaped rod 5 is adjusted to the appropriate position, the slider 504 is released, and the elastic force of the spring 503 pushes the slider 504 to reset, so that the positioning rod 505 is reinserted into the positioning hole 402, thereby fixing the U-shaped rod 5 in the corresponding position.
[0037] Reference Figure 1 and Figure 5 A mounting base 7 is fixed on the side plate 2. The top of the mounting base 7 has three reserved holes. A cylinder 8 is fixed on the top of the mounting base 7. The moving end of the cylinder 8 passes through one of the reserved holes and is fixedly connected to the top of the mounting frame 9. When the cylinder 8 works, the piston rod extends and retracts to drive the mounting frame 9 to move up and down, providing downward pressure to the die-cutting die 15 to realize the die-cutting operation of the cardboard.
[0038] Reference Figure 5 The other two reserved holes are fitted with guide rods with gaps. The bottom of the two guide rods is fixed to the top of the mounting frame 9. The guide rods play a guiding role during the lifting and lowering of the mounting frame 9, ensuring that the mounting frame 9 moves vertically up and down, and avoiding a decrease in die-cutting accuracy due to shaking or offset.
[0039] Working principle: When processing cardboard of different sizes, first loosen the hand screw 13 so that its bottom protrudes from the limiting hole 1101. Then rotate the rotating block 11 to reverse the positions of the two die-cutting blades 15. Tighten the hand screw 13 again to insert it into the corresponding limiting hole 1101 to fix the rotating block 11. Next, adjust the distance between the two positioning components 6 according to the size of the cardboard, and move the sliders 504 protruding from the grooves 501 in the corresponding directions. The sliders 504 are in the grooves 501. After the part slides, it will compress the spring 503. At this time, the positioning rod 505 moves with the movement of the slider 504, so that the positioning rod 505 extends out of the original positioning hole 402. The operator can then move the U-shaped rod frame 5 to slide on the sliding groove 401, thereby driving the positioning component 6 to move. When it moves to the corresponding position, after releasing the slider 504, the slider 504 moves in the opposite direction under the reset of the spring 503, so that the positioning rod 505 passes into the corresponding positioning hole 402 to fix the U-shaped rod frame 5.
[0040] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
