Description

Technical Field

[0001] This utility model relates to the field of aluminum-plastic cap processing technology, specifically to an automatic riveting machine for aluminum-plastic caps. Background Technology

[0002] Aluminum-plastic caps are widely used in the food and pharmaceutical industries. Riveting is a mechanical connection process that uses rivets to firmly connect two or more parts together.

[0003] For example, an automatic riveting machine for aluminum-plastic caps, with authorization announcement number "CN222004477U", may cause the aluminum-plastic cap to be thrown out due to centrifugal force during the operation of the drive mechanism. The riveting punch then picks up the plastic cap and transports it above the aluminum cap for riveting. After riveting, a baffle prevents the aluminum-plastic cap from being thrown off the drive mechanism. However, the automatic riveting machine generates impact force when the riveting punch presses down during the riveting operation. This impact force can cause the plastic cap to shift position, resulting in inaccurate riveting between the plastic cap and the aluminum cap. Utility Model Content

[0004] The purpose of this invention is to solve the problem that when the riveting punch presses down to perform the riveting operation, it will generate an impact force, which will cause the position of the plastic cover to change, resulting in inaccurate riveting position between the plastic cover and the aluminum cover. Therefore, an automatic riveting machine for aluminum-plastic covers is proposed.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

Both ends of the sliding rod are fixedly connected to the housing. The outer wall of the lower square block is slidably connected to the housing.

[0024] Working principle:

[0025] When using an automatic riveting machine for aluminum-plastic caps:

[0026] Feeding:

[0027] Place the rivet 8 above the horizontal block 302. Pass the aluminum cap and plastic cap through the through hole in the middle of the rivet 8 and place them on the rivet 8. After the aluminum cap and plastic cap are placed, adjust the position of the rivet 8 so that the rivet 8 is in the middle of the horizontal block 302 to facilitate subsequent riveting. It can be further explained that the first electric telescopic rod 301 can make the upper end of the rivet head of the rivet 8 flush with the upper end of the vertical block 2, thereby riveting rivets and aluminum-plastic caps of various sizes.

[0028] Securing the aluminum and plastic caps:

[0029] Start the second electric telescopic rod 5. The output end of the second electric telescopic rod 5 moves, causing the housing 6 to slide on the curved plate 4. The movement of the housing 6 causes the fixed block 707 to move until the fixed block 707 contacts the plastic cover (the upper cover). Close the second electric telescopic rod 5. Start the servo motor 701. The servo motor 701 is connected to the battery via wires. The battery is equipped with a switch. The output shaft of the servo motor 701 rotates, causing the round rod 702 to rotate (e.g., ...). Figure 2The rotation of the round rod 702 drives the rotation of the threaded rod 703. The two threaded rods 703 have opposite thread directions. The rotation of the threaded rod 703 drives the two threaded blocks 704 to move outward simultaneously. The movement of the threaded blocks 704 drives the square block 705 to slide on the slide rod 706. The slide rod 706 limits the threaded blocks 704 to prevent them from rotating with the rotation of the threaded rod 703. The movement of the square block 705 drives the two fixed blocks 707 to move outward on the plastic cover until the outer ends of the two fixed blocks 707 are flush with the outer ends of the plastic cover (to prevent warping) (to prevent warping when riveting the aluminum cover and the plastic cover). Then, the servo motor 701 is turned off and the second electric telescopic rod 5 is started. The output end of the second electric telescopic rod 5 moves downward. When the second electric telescopic rod 5 makes the two fixed blocks 707 press against the plastic cover in the above manner, the second electric telescopic rod 5 is turned off, completing the fixing of the aluminum cover and the plastic cover and preventing the plastic cover and the aluminum cover from shifting during riveting.

[0030] Riveting of aluminum-plastic caps:

[0031] When the third electric telescopic rod 9 is activated, its output end moves, causing the pressure block 10 to move. The pressure block 10 then causes the cylinder 12 to slide on the cylinder 11. The cylinder 11 provides sliding support for the cylinder 12. When the pressure block 10 contacts the rivet 8 (which is made of a ductile metal such as aluminum or aluminum alloy), the downward movement of the third electric telescopic rod 9 generates pressure. This strong pressure is transmitted to the rivet 8. Under this pressure, the rivet 8's material properties cause it to undergo plastic deformation, and the rod portion of the rivet 8 will... Under pressure, it expands outwards, filling the gap between the through holes of the aluminum cap and the plastic cap, and tightly squeezing the aluminum cap and the plastic cap together. Finally, the aluminum cap and the plastic cap are firmly connected into a whole by the rivet 8, achieving the riveting effect. The second electric telescopic rod 5 moves the fixing block 707 away from the aluminum-plastic cap, and the riveted aluminum-plastic cap is removed. The third electric telescopic rod 9 moves the pressure block 10 away from the aluminum-plastic cap, and the servo motor 701 resets the two fixing blocks 707. All power is turned off, thus completing the workflow of the automatic aluminum-plastic cap riveting machine.
