[0031] Specifically, please refer to Figure 2 and in combination with Figure 1 The main motor 2 is connected with the conical tension block 10 through the shaft body 6, which penetrates the lifting push plate 8 and the feeding push plate 9, wherein the shaft body 6 comprises a sliding shaft upper and lower part 4 and a rotating shaft 6, the sliding shaft upper and lower part 4 is connected with the main motor 2 and the shaft body 6; the shaft body 6 is connected with the sliding shaft upper and lower part 4 and the shrinkage disc 12. When the main motor 2 starts, the sliding shaft upper and lower part 4 is controlled to rotate, the sliding shaft upper and lower part 4 drives the shaft body 6 to rotate, so that the shrinkage disc 12 connected with the shaft body 6 rotates, and the sliding shaft upper and lower part 4 can slide up and down, when the shrinkage disc 12 moves up and down, the sliding shaft upper and lower part 4 can move up and down, so that the main motor 2 controls the rotation of the shrinkage disc 12, and also does not limit the movement of the shrinkage disc 12 in other directions.

[0032] The first electric cylinder 3 is fixedly connected with the lifting push plate 8 through an extendable shaft, and the shaft body is fixedly connected with the lifting push plate 8, which can be fixed by a nut or welding. When the first electric cylinder 3 is started, the lifting push plate 8 will be driven to move up and down. The second electric cylinder 1 is fixedly connected with the feeding push plate 9 through an extendable shaft, and when the second electric cylinder 1 is started, the feeding push plate 9 will be driven to move up and down. The packaging device based on the rotary rolling process further comprises a guide rod 7, which penetrates the lifting push plate 8 and is fixed on the feeding push plate 9, and is used for guiding the feeding push plate 9 and stabilizing the balance of the up-down movement of the feeding push plate 9.

[0033] When the lifting push plate 8 moves up and down, the lifting push plate 8 is fixedly connected with the shaft body 6, so that the lifting push plate 8 drives the shaft body 6 to move up and down, thereby driving the shrink disc 12 connected with the shaft body 6 to move up and down. The lifting push plate 8 can control the position of the shrink disc 12 and the L-shaped bearing frame 11 arranged thereon by moving up and down.

[0034] As shown in Figures 3-5 , the L-shaped bearing frame 11 comprises a deflection block 111 and a rotating shaft 112 connected with each other. The deflection block 111 is connected with the upper end of the rotating shaft 112, the lower end of the rotating shaft 112 penetrates the shrink disc 12 and is connected with the L-shaped tool holder 13; the shrink disc 12 fixes the up-down position relationship of the rotating shaft 112. The deflection block 111 is arranged at a certain angle α or a predetermined angle with the L-shaped tool holder 13, as shown in Figure 5 . The number of L-shaped bearing frames 11 is N (N is a positive integer not equal to 0), and the best is an even number, and two by two are centrally symmetric, at the same time, the workpiece is fixed in the workpiece station, which prevents the workpiece from swinging to the greatest extent, controls the necking precision, and the number of L-shaped bearing frames 11 is the same as that of L-shaped tool holders 13; the deflection block 111 comprises a pulley 113, and the pulley 113 is in contact with the conical tension block 10 at all times and slides thereon

[0035] As shown in Figure 6 , the pulley 113 is installed on the deflection block 111 by being sleeved on the pulley shaft 1130. The pulley shaft 1130 penetrates the deflection block 111.

[0036] Continuing to refer to Figures 3-6As shown, the frustum-shaped tension block 10 includes an upper surface, a lower surface and a working surface between the upper surface and the lower surface; during the descending process of the frustum-shaped tension block 10, the working surface is in contact with the pulley 113 of the L-shaped bearing frame 11, the pulley 113 slides to the upper part of the working surface, due to the thick end of the upper end of the frustum-shaped tension block 10, the deflection block 111 deflects outward relative to the bearing center of the L-shaped bearing frame 11 to form a first angle, and the L-shaped tool holder 13 deflects inward relative to the bearing center of the L-shaped bearing frame 11 to form a second angle, and the first angle is equal to the second angle.

[0037] More specifically, the frustum-shaped tension block 10 is in a conical structure with a large upper part and a small lower part, and the frustum-shaped tension block 10 includes an upper surface, a lower surface and a working surface in the middle, the longitudinal section of the working surface is one of a straight line segment and a lofted curve, during the descending process of the frustum-shaped tension block 10, the working surface is in contact with the pulley 113 of the L-shaped bearing frame 11 all the time, the pulley 113 slides to the upper part of the working surface, due to the thick end of the upper end of the frustum-shaped tension block 10, the deflection block 111 deflects outward relative to the bearing center of the L-shaped bearing frame 11 to form a first angle, and due to the fact that the deflection block 111 and the L-shaped tool holder 13 are both fixed on the rotating shaft 112, the L-shaped tool holder 13 deflects inward relative to the bearing center of the L-shaped bearing frame 11 to form a second angle, and the deflection angles (i.e. the first angle and the second angle) are the same.

[0038] Further, the tensioning disc 12 includes a reset mechanism (not shown in the figure for the sake of simplicity of illustration), the two ends of the reset mechanism are connected to the two deflection blocks 111 at the center-symmetrical positions, so that the pulley 113 of the deflection block 111 is always in contact with the working surface of the frustum-shaped tension block 10, when the frustum-shaped tension block 10 descends, the reset mechanism is tightened, and when the frustum-shaped tension block 10 ascends, the pulley 113 is still ensured to be in contact with the frustum-shaped tension block 10 under the tightening action of the reset mechanism.

[0039] During production, flat tool bits are selected and installed on the L-shaped tool holder 13, the distance between the symmetrically arranged pair of tool bits decreases during the descending process of the frustum-shaped tension block 10, and a compression force is generated on the workpiece, the tool bits rotate while compressing the workpiece, and through multiple small amounts of feed and rotation, the diameter of the neck of the bottle is finally reduced, that is, process C is completed.

[0040] When the feeding push plate 9 moves up and down, the conical tension block 10 fixed in the feeding push plate 9 will move up and down with the feeding push plate 9. When the conical tension block 10 is surrounded by the L-shaped bearing frame 11 arranged on the shrink disc 12, and when the L-shaped bearing frame 11 moves downward relative to the shrink disc 12, the conical tension block 10 will push the upper part of the L-shaped bearing frame 11 around it to move outward, while the lower part of the L-shaped bearing frame 11 moves inward. The lower part of the L-shaped bearing frame 11 is provided with an L-shaped tool holder 13, and the L-shaped tool holder 13 is provided with a forming tool 14. When the L-shaped bearing frame 11 moves inward, the forming tool 14 directly cuts the workpiece located at the center of the forming tool 14 when it drops to a certain height, and under the assistance of the rotating force, the bottle neck is pressed out, which is used to fix the inner bottle, and the bottle neck pressing process E (such as the E figure in Figure 7 , that is, the finished product figure) is completed. At this time, the packaging of the workpiece is completed.

[0041] Further, a workpiece station is arranged below the forming tool 14, and the workpiece is fixed on the workpiece station. The power of the first electric cylinder 3 can push the lifting push plate 8 and the multiple elements below it downward, so that the position of the forming tool 14 corresponds to the workpiece station. When the packaging of the workpiece on the workpiece station is completed, the position of the forming tool 14 will move upward to loosen the packaged workpiece. The shape of the forming tool 14 can be set according to the required packaging shape, such as a cylindrical body, a trapezoidal body, a cylindrical body with a convex point, etc.

[0042] In order to ensure the packaging quality of the workpiece and improve the safety of the packaging device, a sensor system is arranged below the workpiece station. The sensor system can sense the state of the workpiece station and send a feedback signal.

[0043] The packaging device based on the rotary rolling process also includes a power-off control system, which can control the packaging device to be powered off according to the feedback signal of the sensor system, so as to ensure that the packaging device can be powered off when a fault occurs, thereby protecting the safety of the packaging device and the workers.

[0044] The packaging device based on the rotary rolling process is stabilized by support columns, wherein the support columns include a first vertical column 5, a second vertical column 15, and a support plate 16; the main motor 2, the first electric cylinder 3, and the second electric cylinder 1 are arranged on the upper plate surface of the support plate 16; one end of the first vertical column 5 is fixed to the upper plate surface of the support plate 16, and the other end is fixed with the main motor 2; the second vertical column 15 is fixed to the lower plate surface of the support plate 16.

[0045] In addition, as Figure 7As shown, the application also proposes a rotary rolling process using the above-mentioned packaging device based on the rotary rolling process, which includes: sequentially packaging the workpiece according to the order of inner bottle loading, neck shrinkage, top edge sealing and neck pressing, or sequentially packaging the workpiece according to the order of inner bottle loading, neck shrinkage, neck pressing and top edge sealing, to obtain finished products.

[0046] For the entire packaging process, for example, the bottle is filled with liquid medicine (i.e. the workpiece), and the inner bottle is coated with an aluminum bottle process, which can be as shown: Figure 7 As shown: Step 1, inner bottle loading (A-B): load the inner bottle into the aluminum bottle and maintain the appropriate height. Step 2, neck shrinkage (C): shrink the neck diameter. Step 3, top edge sealing (D): top edge sealing to form the upper limit of the inner bottle. Step 4, neck pressing (E): press out two necks, which are used to fix the inner bottle (packaging is completed). The process sequence can be ABCDE or ABDCE. Among them, the top edge sealing process (D) seals the top surface to form the upper limit of the inner bottle, which can be performed using other equipment.
