[0059] As an embodiment of the utility model, referring to Figure 1 , Figure 2 and Figure 4 , the intermittent rotating mechanism comprises:

[0060] The rotating cylinder 16 is rotatably connected with the bottom plate 1 at the bottom end and is connected with the placing plate 19 at the top end.

[0061] Oblique straight grooves 17 are arranged on the rotating cylinder 16, and are arranged in a circle with equal intervals, and are communicated with each other between two adjacent groups, and are composed of an oblique groove and a straight groove, and the bottom of the oblique groove is located in the middle of the straight groove, and the top of the oblique groove is communicated with the top of the straight groove;

[0062] The abutting block 18 is arranged in the straight groove and located at the top of the oblique groove, and the top of the abutting block 18 is a bevel structure, and the bottom of the outer wall of the abutting block 18 is a bevel structure;

[0063] The folding rod 13 is connected with the strip frame 5 at the top end;

[0064] The sliding cylinder 14 is slidably connected with the bottom end of the folding rod 13, and is movably clamped with the oblique straight grooves 17, and the end close to the abutting block 18 is a bevel structure;

[0065] The elastic member two 15 is connected with the sliding cylinder 14 at one end and connected with the bottom end of the folding rod 13 at the other end.

[0066] When the strip frame 5 is located at the highest position, the sliding cylinder 14 is located at the top of the abutting block 18 and the top of the straight groove, the strip frame 5 drives the folding rod 13 to move downward, the folding rod 13 drives the sliding cylinder 14 to move downward, so that the sliding cylinder 14 abuts against the top of the abutting block 18, under the action of the extrusion force, the abutting block 18 drives the rotating cylinder 16 to rotate, and the sliding cylinder 14 continues to move downward to abut against the oblique groove, the extrusion force drives the rotating cylinder 16 to continue to rotate and drives the placing plate 19 to rotate, when the sliding cylinder 14 moves into the straight groove, the rotating cylinder 16 cannot continue to rotate, at this time, the placing plate 19 rotates by a certain angle, so that the plastic product to be processed is located at the bottom of the cutting knife 8, because the bottom of the oblique groove is higher than the bottom of the straight groove, when the sliding cylinder 14 moves in the straight groove, the strip frame 5 can continue to move downward, so that the fixing mechanism fixes the plastic product, when the trimming is completed, the strip frame 5 moves upward and drives the sliding cylinder 14 to move upward, when the sliding cylinder 14 abuts against the bottom of the abutting block 18, because the side wall of the bottom of the abutting block 18 is a bevel structure, the sliding cylinder 14 moves transversely and extrudes the elastic member two 15, when the sliding cylinder 14 moves to the top of the abutting block 18, under the action of the reaction force of the elastic member two 15, the sliding cylinder 14 returns to the original position, so as to be moved next time. The elastic member two 15 can be a spring, a spring piece or the like.

[0067] As an embodiment of the utility model, please refer to Figure 1 The fixing mechanism comprises:

[0068] The fixing cylinder 9 is connected with the connecting plate 6;

[0069] The sliding rod 11 is slidably connected with the fixing cylinder 9;

[0070] The elastic element 10 is connected to the fixed cylinder 9 at its top end and to the top end of the sliding rod 11 at its bottom end.

[0071] The pressure plate 12 is connected to the bottom end of the sliding rod 11.

[0072] The connecting plate 6 moves downward, causing the pressure plate 12 to move downward synchronously. When the pressure plate 12 comes into contact with the surface of the plastic product, the connecting plate 6 continues to move downward, compressing the elastic element 10 and causing it to undergo elastic deformation. Under the reaction force of the elastic element 10, the pressure plate 12 fixes the plastic product. The elastic element 10 can be a spring, sheet metal, etc.

[0073] As one embodiment of this utility model, please refer to Figure 1 It also includes:

[0074] Connecting frame 21 is connected to base plate 1;

[0075] Rotate ball 22 to rotatably connect with connecting frame 21 and abut against placement plate 19.

[0076] The placement plate 19 is supported by the rotating ball 22, which ensures that the placement plate 19 can rotate smoothly.

[0077] The working principle of this utility model is as follows: A plastic product is placed on the placement plate 19, and the limiting plate 20 limits the plastic product. The motor drives the rotating disk 3 to rotate, and the rotating disk 3 drives the clamping rod 4 to rotate. Under the limitation of the limiting rod 7, the frame 5 moves longitudinally back and forth, driving the connecting plate 6 to move longitudinally back and forth. When the frame 5 moves downward, it drives the bending rod 13 to move downward, and the bending rod 13 drives the sliding cylinder 14 to move downward, so that the sliding cylinder 14 abuts against the top of the abutting block 18. Since the top of the abutting block 18 has a beveled structure, under the action of the extrusion force, the abutting block 18 drives the rotating cylinder 16 to rotate. At the same time, the sliding cylinder 14 continues to move downward until it abuts against the inclined groove. The extrusion force causes the rotating cylinder 16 to continue rotating, driving the placement plate 19 to rotate. When the sliding cylinder 14 moves into the straight groove, the rotating cylinder 16 can no longer rotate. At this time, the placement plate 19 rotates at a certain angle, so that the plastic product to be processed is in the cutting position. At the bottom of the blade 8, because the bottom of the inclined groove is higher than the bottom of the straight groove, when the sliding cylinder 14 moves in the straight groove, the frame 5 can continue to move downward, driving the pressure plate 12 to move downward synchronously. When the pressure plate 12 abuts against the surface of the plastic product, the connecting plate 6 continues to move downward, squeezing the elastic element 10, causing the elastic element 10 to undergo elastic deformation. Under the reaction force of the elastic element 10, the pressure plate 12 fixes the plastic product, and the cutting blade 8 cuts the edge of the plastic product. After the edge is cut, the frame 5 moves upward, driving the sliding cylinder 14 to move upward. When the sliding cylinder 14 moves to abut against the bottom of the abutting block 18, because the bottom side wall of the abutting block 18 is an inclined structure, the sliding cylinder 14 moves laterally to squeeze the elastic element 15. When the sliding cylinder 14 moves to the top of the abutting block 18, under the reaction force of the elastic element 15, the sliding cylinder 14 returns to its original position for the next movement.

[0078] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0079] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
