[0033] Compared with the prior art, the present invention has the following beneficial effects:

[0034] 1. The present invention clamps shells of different sizes to be cut by using multiple groups of elastically arranged supporting rods. After the shells are placed, due to the different weights of the shells, the downward positions of the shells relative to the supporting rods are different. At this time, the storage plate is manually moved down, and the storage plate drives the leveling frame and the clamping block to move toward the shell. No matter whether the shell is higher than the supporting rod or lower than the supporting rod, only when the second leveling block contacts the shell and squeezes the third airbag, and the first leveling block contacts the supporting rod and squeezes the second airbag, the upper surface of the shell will be flush with the supporting rod. At this time, the internal gas of the second airbag and the third airbag is discharged to the fourth airbag, and the fourth airbag expands to push the top block to be inserted into the slot, so that the slot retreats and no longer presses the elastically arranged fixing block Limiting, at this time, the fixed block is inserted into the interior of the fixed groove to limit the sliding storage plate. At the same time, when the fixed block is inserted into the interior of the fixed groove, the fifth airbag is squeezed, and the gas inside the fifth airbag is discharged into the interior of the first airbag. The first airbag expands and pushes the first push rod to be inserted into the third through hole opened on the adjacent supporting rod, so as to limit the adjacent supporting rod. At the same time, the second push rod elastically arranged inside the supporting rod is pushed by the first push rod and inserted into the adjacent second through hole. At this time, the push block slidably arranged inside the second through hole is inserted into the third through hole opened by another group of supporting rods adjacent to the supporting rod, so that all the supporting rods are limited, thereby realizing the fixed clamping of shells of different sizes;

[0035] 2. The two sets of clamping blocks are arranged to be slidable. When cutting a shell having an opening, the spacing between the two sets of sliding clamping blocks can be adjusted to the same size as the shell opening, thereby ensuring that the second leveling block arranged under the clamping blocks can contact the openings of shells of different sizes;

[0036] 3. After the top block is pushed into the slot, some of the gas content inside the second airbag and the third airbag will remain. The remaining part can ensure that a certain gap is left between the leveling frame and the top holding rod or between the clamping block and the shell. The gap can allow the cutting knife to pass through, and when the cutting knife passes through, it will squeeze the remaining gas inside. When this gas is squeezed, it will be discharged into the air storage cavity. BRIEF DESCRIPTION OF THE DRAWINGS

[0077] A second limiting groove 58 is formed on one side wall of the fixing block 51, and a matching sixth receiving groove 59 is formed on the inner side wall of the fourth receiving groove 52 at a position corresponding to the second limiting groove 58, a matching inserting block 61 is inserted in the sixth receiving groove 59, and a sixth elastic member 60 is provided between the inserting block 61 and the sixth receiving groove 59, and the inserting block 61 is elastically inserted in the second limiting groove 58 through the sixth elastic member 60;

[0078] A slot 62 is provided on one side wall of the insert block 61, and the cross section of the slot 62 is a triangular structure. A matching fifth receiving slot 54 is provided on the side wall of the sixth receiving slot 59 at a position corresponding to the slot 62. A matching second top block 57 is inserted and arranged inside the fifth receiving slot 54. A matching fourth airbag 55 is arranged between the second top block 57 and the fifth receiving slot 54, and a matching fifth elastic member 56 is arranged inside the fourth airbag 55.

[0079] A second exhaust duct 41 and a third exhaust duct 42 are respectively connected between the fourth airbag 55 and the third airbag 38 and the second airbag 31, and the second exhaust duct 41 is connected to the third exhaust duct 42;

[0080] A matching air storage cavity 63 is provided inside the storage plate 3 at a position corresponding to the fourth air bag 55, the air storage cavity 63 is communicated with the fourth air bag 55, and a matching sealing plate 65 is slidably provided inside the air storage cavity 63, a seventh elastic member 64 is provided between the side wall of the sealing plate 65 and the inside of the air storage cavity 63, the sealing plate 65 elastically slides inside the air storage cavity 63 through the seventh elastic member 64, and the elastic force of the seventh elastic member 64 is greater than the elastic force of the fifth elastic member 56;

[0083] After the shell is placed, due to the different weights of the shell, the shell moves down to different positions relative to the supporting rod 4. At this time, the storage plate 3 is manually moved down, and the storage plate 3 drives the leveling frame 29 and the clamping block 35 to move toward the shell. No matter the shell is higher or lower than the supporting rod 4, only when the second leveling block 37 contacts the shell and squeezes the third airbag 38, and the first leveling block 32 contacts the supporting rod 4 and squeezes the second airbag 31, the upper surface of the shell will be flush with the supporting rod 4. At this time, the internal gas of the second airbag 31 and the third airbag 38 is discharged to the fourth airbag 55. The fourth airbag 55 collides and pushes the second top block 57 to be inserted into the slot 62, so that the slot 62 retreats and no longer limits the elastically set fixed block 51.

When cutting a shell with an opening, the spacing between the two groups of sliding clamping blocks 35 can be adjusted to the same size as the shell opening size, thereby ensuring that the second leveling block 37 set below the clamping block 35 can contact the openings of shells of different sizes.

[0084] Embodiment 4:

[0085] like Figure 1 and Fig.10As shown, the structure of the shell manufacturing cutting mold disclosed in the fourth embodiment of the present invention is basically the same as that in the third embodiment, except that:

[0086] Two groups of symmetrically distributed automatic telescopic rods 25 are fixedly provided on the lower end surface of the storage plate 3, and the two groups of automatic telescopic rods 25 are respectively located on both sides of the leveling frame 29;

[0087] The output ends of the two groups of automatic telescopic rods 25 are fixedly connected to the connecting rod 26, and the lower end surface of the connecting rod 26 is provided with a third clearance groove 49, and a matching second transmission screw 50 is rotatably arranged inside the third clearance groove 49, and one end of the second transmission screw 50 passes through the side wall of the connecting rod 26 and is connected to the transmission motor 27, and a cutting knife 28 is screwed between the two groups of the transmission motors 27;

[0088] The height of the connecting rod 26 is adjusted by two sets of automatic telescopic rods 25, thereby adjusting the position of the cutting knife 28 corresponding to the shell, and then the cutting knife 28 can cut the shell through the cooperation of the transmission motor 27 and the second transmission screw rod 50.

[0089] The specific solution is as follows: the shell to be cut is placed at the center position above the multiple groups of supporting rods 4. Due to the weight of the shell itself, the supporting rods 4 in contact with the shell are pressed down. If the opening of the shell faces upward, the spacing between the two groups of clamping blocks 35 is adjusted so that the second leveling block 37 below the clamping block 35 can contact the wall of the shell, and the contact position is lower than the convex point of the shell to be cut. During the adjustment, the extrusion plate 5 can be adjusted along with the movement of the clamping block 35.

[0090] Then the storage plate 3 is manually moved down, and the storage plate 3 drives the leveling frame 29 and the clamping block 35 to move toward the shell. No matter the shell is higher or lower than the top holding rod 4, only when the second leveling block 37 contacts with the shell and squeezes the third air bag 38, and the first leveling block 32 also contacts with the top holding rod 4 and squeezes the second air bag 31, the upper surface of the shell will be flush with the top holding rod 4. At this time, the internal gas of the second air bag 31 and the third air bag 38 is discharged to the fourth air bag 55, and the fourth air bag 55 expands and pushes the second top block 57 to be inserted into the slot 62, so that the slot 62 retreats and no longer limits the elastically set fixed block 51. At this time, the fixed block 51 is inserted into the fixed groove 7 to limit the sliding storage plate 3 At the same time, when the fixing block 51 is inserted into the fixing groove 7, the fifth airbag 66 is squeezed, and the internal gas of the fifth airbag 66 is discharged into the first airbag 15. The first airbag 15 expands and pushes the first push rod 17 to be inserted into the third through hole 20 opened on the adjacent support rod 4, so as to limit the adjacent support rod 4. At the same time, the second push rod 21 elastically arranged inside the support rod 4 is pushed by the first push rod 17 and inserted into the adjacent second through hole 18. At this time, the push block 19 slidably arranged inside the second through hole 18 is inserted into the third through hole 20 opened in another group of support rods 4 adjacent to the support rod 4, so that all the support rods 4 are limited, thereby realizing the fixed clamping of shells of different sizes;

[0091] Then, the height of the connecting rod 26 is adjusted by two sets of automatic telescopic rods 25, thereby adjusting the position of the cutting knife 28 corresponding to the shell. Then, through the cooperation of the transmission motor 27 and the second transmission screw 50, the cutting knife 28 passes between the shell and the leveling frame 29 to cut the protrusions on the shell.

[0092] The present invention is intended to cover all such substitutions, modifications and variations that fall within the broad scope of the appended claims. Therefore, any omissions, modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
