[0002] In the field of workpiece processing, especially when processing thermos cups and thermos pots, shrinking the mouth of the blank is a very common process. Shrinking refers to the process of shrinking the mouth of the pre-formed cylindrical or pipe blank through a shrinking die. The existing shrinking machines for thermos cups basically use a motor to drive a single feed tray, and a single feed tray drives a single cup body to shrink the mouth. The operation is cumbersome and inefficient. There are also single shrinking machines equipped with two motors and two feed trays to shrink two cup bodies at the same time. This method makes the overall manufacturing cost of the equipment high, the volume is large, and it is not compact enough. In addition, it is also necessary to take out and change materials after the shrinking is completed, and the efficiency is still not high. Summary of the invention

The arc-shaped rack 12 guides the transition gear 11 during the process in which the transition gear 11 approaches and meshes with the main gear 10, so that the tooth top of the transition gear 11 will not overlap with the tooth top of the main gear 10; the frame 1 also includes a horizontally arranged base plate 13, the positioning component 4 is installed on the base plate 13, the outer ring of the turntable 6 is provided with a first groove 14, and the base plate 13 is provided with a second groove 15. The first groove 14 on the turntable 6 can be rotated to form a third groove 16 opposite to the second groove 15, and a longitudinally movable positioning rod 18 is arranged above the third groove 16. The positioning rod 18 is arranged on the frame 1 and driven by a cylinder 23, and the bottom of the positioning rod 18 is a sphere. The positioning rod 18 can be inserted into the third groove 16, so that the turntable 6 and the base plate 13 are positioned by the positioning rod 18 to maintain stability during shrinking. The first groove 14 and the second groove 15 are semicircular with the same diameter, and the third groove 16 is circular.

[0022] The arc-shaped rack 12 coincides with the center of the circle of the rotating disk 6. The first end 121 of the arc-shaped rack 12 has a first chamfer, and the second end 122 of the arc-shaped rack 12 has a second chamfer. The transition gear 11 meshes with the arc-shaped rack 12 from the first end 121, and meshes with the main gear 10 after leaving the second end 122. The angle of the first chamfer is smaller than the angle of the second chamfer.

[0023] In order to ensure that the cup body fixing frame 5 is securely installed and easy to disassemble, the cup body fixing frame 5 and the rotating disk 6 are matched with a Morse taper.

[0024] The frame 1 is also provided with a support base 20 that is driven by a screw rod 19 to move longitudinally, the transverse guide rails 2 are horizontally arranged on both sides of the support base 20, a roller support seat 21 is slidably arranged on the transverse guide rails 2, the roller is installed at the end of the roller support seat 21, and the other end of the roller support seat 21 is driven by an independent servo motor 22.

[0025] The end of the base plate 13 close to the turntable 6 is provided with a fourth groove 17 matching the outer ring shape of the turntable 6. The gap between the turntable 6 and the fourth groove 17 is 1 mm.

[0026] The working process of the present invention is as follows: two cup bodies to be processed are placed on two cup body fixing frames 5 far away from the shrinking roller 3, and the first motor 7 and the main motor 9 are started. The first motor 7 drives the transmission gear 8 under the turntable 6 to rotate the turntable 6 counterclockwise by 180° so that the two cup body fixing frames 5 loaded with cup bodies are placed under the positioning component 4. During this rotation process, the transition gear 11 meshing with the transmission gear 8 starts to mesh with the arc-shaped rack 12 from the first end 121 and leaves the arc-shaped rack 12 from the second end 122 and then meshes with the main gear 10. The positioning component 4 is driven by an independent cylinder to press down and fix the cup body without affecting its rotation. At this time, the main gear 10 of the main motor 9 meshes with the transition gear 11 and drives it to rotate. The transition gear 11 also drives the two transmission gears 8 meshing with it to rotate, so that the cup body rotates. During this process, the first groove 14 rotates to the opposite side of the second groove 15 to form a third groove 16. Then the cylinder 23 drives the positioning rod 18 to insert the ball at the bottom of the positioning rod 18 into the third groove 16, so that the turntable 6 and the base plate 13 are supported and positioned. Then the servo motor 22 drives the shrinking roller 3 to approach the cup body to be processed and contact and extrude it to shrink. At the same time, a new cup body to be processed can be placed on the other two cup body fixing frames 5. After shrinking for a period of time, the positioning component 4 and the shrinking roller 3 return to their positions, the first motor 7 drives the turntable 6 to rotate 180° counterclockwise, and the transition gear 11 leaves and releases the meshing with the main gear 10. The cup body with the shrinking is removed and reloaded. At the same time, another new transition gear 11 meshes with the main gear 10 and rotates with it, and a new set of cup body shrinking process is restarted.

[0027] The above is only an embodiment of the present invention and does not limit the present invention in any form. Simple modifications, equivalent changes or modifications made without departing from the technical solution of the present invention all fall within the protection scope of the present invention.
