[0002] Soft mists have appeared more and more in our lives. The production of soft mist products includes the assembly and shrinking of aluminum tubes and medicine bottles. The soft mist assembly and shrinking machine is used for the assembly and shrinking of aluminum tubes and medicine bottles of soft mist products. The existing soft mist assembly and shrinking machine generally includes an aluminum tube fixing mechanism and an aluminum tube shrinking mechanism. The aluminum tube shrinking mechanism is arranged above the aluminum tube fixing mechanism, and the aluminum tube on the aluminum tube fixing mechanism is rotated and shrunken; the aluminum tube shrinking mechanism generally includes a clamping cylinder assembly for clamping the top of the aluminum tube and a rotating assembly for driving the clamping cylinder assembly to rotate. The clamping cylinder assembly first clamps the top of the aluminum tube, and then rotates around the center of the aluminum tube under the drive of the rotating assembly to achieve the shrinking of the aluminum tube. The clamping action of the clamping cylinder assembly and the rotating action of the rotating assembly are generally carried out successively, which can generally only meet the requirements of the cylinder of a certain material, and has poor adaptability. For the shrinking of the cylinder of other different materials, it is easy to tear the cylinder during the shrinking process. Utility Model Content

[0029] Figures 1 to 4 An embodiment of the container shrinking system of the utility model is shown. The container shrinking system of this embodiment includes a container fixing device 1 and a container shrinking device 2. The container shrinking device 2 includes a lifting mechanism 21, a rotating seat 22, a rotating shaft 23, a rotating driving mechanism 24 and a differential mechanism 25. The rotating seat 22 and the rotating shaft 23 are coaxially arranged on the lifting mechanism 21. The rotating driving mechanism 24 is connected to the rotating seat 22 and is connected to the rotating shaft 23 through the differential mechanism 25, and is used to drive the rotating seat 22 and the rotating shaft 23 to rotate at a differential speed. The rotating seat 22 is provided with a plurality of rotating seats 22 above the container fixing device 1. The clamping mechanism 26 is arranged at intervals in the center, and the clamping mechanism 26 includes a first swing arm 261, a second swing arm 262, a clamping wheel 263 and a swinging wheel 264. One end of the first swing arm 261 and the second swing arm 262 are connected and rotatably set on the rotating seat 22. The clamping wheel 263 is arranged at the other end of the first swing arm 261 and is used to clamp the top of the container 3. The swinging wheel 264 is arranged at the other end of the second swing arm 262. A plurality of gradient surfaces 231 are arranged on the circumferential side of the rotating shaft 23. One end of the gradient surface 231 is closer to the center of the rotating shaft 23 than the other end, and each swinging wheel 264 is in one-to-one contact with each gradient surface 231.

[0030] The working process of the container shrinking system is as follows: first, the container 3 (such as an aluminum cylinder) is fixed on the container fixing device 1; secondly, the lifting mechanism 21 drives the rotating seat 22 to descend, so that each clamping wheel 263 is arranged around the top of the container 3; then, the rotating drive mechanism 24 drives the rotating seat 22 and the rotating shaft 23 to rotate at a differential speed, and the swing wheel 264 moves along the gradient surface 231 (the swing wheel 264 moves from the end of the gradient surface 231 close to the center of the rotating shaft 23 to the end far away), pushing the second swing arm 262 to swing, and the second swing arm 262 drives the first swing arm 261 to swing, so that the clamping wheel 263 is pressed against the peripheral side of the top of the container 3, and the shrinking of the top of the container 3 is achieved under the rotating and clamping action of the clamping wheel 263 (the change of the top of the container 3 is as shown in FIG. 2 ). Figure 5 As shown, Figure 5 The left container 3 is in an unshrinking state, and the right container 3 is in a shrinking state). Since the rotary drive mechanism 24 causes the rotary seat 22 and the rotary shaft 23 to rotate at a differential speed, different differential speeds can be used for containers 3 of different materials to prevent the container 3 from being torn during the shrinking process.

[0031] Furthermore, in this embodiment, the abutting wheels 263 are evenly spaced around the center of the rotating seat 22, thereby improving the symmetry of the force applied to the top of the container 3 during the necking process, thereby improving the necking effect.

[0032] Furthermore, in this embodiment, if Figure 2 As shown, the first swing arm 261 and the second swing arm 262 are connected by a swing shaft 265, and the swing shaft 265 is rotatably arranged on the mounting portion 221. The first swing arm 261 and the second swing arm 262 are respectively fixedly connected to both ends of the swing shaft 265 and are respectively located above and below the rotating seat 22. The rotating seat 22 is arranged horizontally, and the swing shaft 265 is arranged vertically.

[0033] Further, in this embodiment, a plurality of mounting portions 221 are arranged at intervals around the center on the peripheral side of the rotating seat 22, and the swing shaft 265 is rotatably mounted on the corresponding mounting portions 221. Specifically, the mounting portions 221 protrude outward from the rotating seat 22 and are penetrated by through holes from top to bottom, and the peripheral side of the rotating seat 22 is penetrated in the through holes and rotatably cooperates with the through holes.

[0034] Furthermore, in this embodiment, the gradual surface 231 protrudes toward the peripheral side of the rotating shaft 23 , so as to facilitate abutment and cooperation with the swing wheel 264 .

[0035] Furthermore, in this embodiment, the lifting mechanism 21 includes a lifting frame 211 and a lifting driving assembly 212 for driving the lifting frame 211 to move up and down, and the rotating seat 22 and the rotating shaft 23 are both arranged on the lifting frame 211. Furthermore, the lifting frame 211 includes a mounting plate, and lifting legs are arranged at the four corners of the mounting plate. The lifting mechanism 21 is connected to the lifting legs to drive the mounting plate to move up and down, and the rotating seat 22 and the rotating shaft 23 are both arranged on the mounting plate.

[0036] Furthermore, in this embodiment, if Figure 2 and Figure 4 As shown, the container fixing device 1 comprises a fixing seat 11, two clamping blocks 12, and a clamping and placing driving mechanism 13. The two clamping blocks 12 are relatively arranged on the fixing seat 11, and the clamping and placing driving mechanism 13 is used to drive the two clamping blocks 12 to move relatively to clamp and place the container 3. The clamping and placing driving mechanism 13 drives the two clamping blocks 12 to move relatively close to and away from each other to clamp and place the container 3. The structure is simple and the operation is convenient.

[0037] Furthermore, in this embodiment, one clamping block 12 is fixedly arranged, and the other clamping block 12 is slidably arranged on the fixing seat 11 and cooperates with the clamping and placing driving mechanism 13. The clamping and placing driving mechanism 13 drives the sliding clamping block 12 to move relative to the fixed clamping block 12 to clamp and place the container 3.

[0038] Furthermore, in this embodiment, the clamping and placing driving mechanism 13 includes an eccentric wheel 131 and a rotating driving assembly 132. The eccentric wheel 131 is rotatably arranged on the fixed seat 11 and abuts against the sliding clamp block 12. The rotating driving assembly 132 is connected to the eccentric wheel 131. The rotating driving assembly 132 drives the eccentric wheel 131 to rotate, and the side of the eccentric wheel 131 away from the center can push the sliding clamp block 12 close to the fixed clamp block 12 to clamp the container 3. Preferably, an elastic reset member is provided between the sliding clamp block 12 and the fixed seat 11, which is used to reset the sliding clamp block 12 to a position where the container 3 is not clamped, and can keep the sliding clamp block 12 and the eccentric wheel 131 in a tight state.

[0039] Furthermore, in this embodiment, the rotation driving assembly 132 is disposed on the fixing seat 11 .
