Description

Technical Field

[0001] This application relates to the field of riveting equipment technology, and more specifically, to a novel aluminum-plastic cap riveting mechanism. Background Technology

[0002] The content in this section provides only background information related to this application and may not constitute prior art.

[0003] When riveting aluminum-plastic caps, the riveting head needs to be heated to a certain temperature to rivet the caps together. Traditional riveting machines use an electric slip ring to heat the riveting head via a heating rod to achieve the riveting. The original heating device mainly consists of an electric slip ring, circuit board, resistive element, and heating rod. During operation, because the heating rod is placed directly inside the riveting head, it cannot be directly heated with a high-voltage power supply to avoid the risk of electric leakage. This heating method is slow in heating speed and temperature control, resulting in extremely high power consumption and hindering production cost control. Therefore, existing riveting machines need to be improved to overcome these problems. Utility Model Content

[0004] In view of this, the purpose of this application is to provide a novel heating method for heating the rivet head, which can quickly heat the rivet head and better control the temperature of the rivet head during operation, thus avoiding power waste.

[0019] See appendix Figure 1-11The present application provides a novel aluminum-plastic cap riveting mechanism, comprising: The frame assembly includes a frame 1, a column 2 and a large top cover 3, wherein the large top cover 3 is fixedly connected to the top of the frame 1 via the column 2, and a riveting disc track 4 is provided below the large top cover 3. The function of the frame 1 assembly is to provide a support and working platform for components such as the riveting disc 7, the heater assembly 24 and the motor 5. Motor 5 is fixed inside the frame 1. The output shaft of motor 5 is fixedly connected to main shaft 6. Main shaft 6 is rotatably connected to top cover 3 via bearings. The function of motor 5 is to provide power to main shaft 6 to drive riveting disc 7 to rotate. Optionally, motor 5 transmits power to reducer via belt, and reducer transmits power to riveting disc main shaft 6 via coupling, thereby providing rotational power to riveting disc 7. The riveting disc 7 includes a turntable 8, a riveting head seat 9, and a rotating base 10. The turntable 8 is fixedly connected to the main shaft 6. The riveting head seats 9 are evenly spaced on the outer circumference of the turntable 8. The rotating base 10 is fixedly connected to the turntable 8 and is located below the riveting head seats 9. A riveting head assembly 11 is placed inside a riveting head seat 9 and is connected to the riveting head seat 9 by a first spring. The pneumatic plate assembly 16 is fixed to the turntable 8 of the riveting disc 7 by bolts. The pneumatic plate assembly 16 is fixedly connected to the main shaft 6.

The bottom of the connecting hole 17 is connected to the punching and riveting head through an air pipe 18. The air plate pressure plate assembly 19 includes an upper air pressure plate 20 and an air pressure tin bronze plate 21.

The bottom of the air pressure tin bronze plate 21 is provided with an air outlet 23, which cooperates with the connecting hole 17. The air plate pressure plate assembly 19 and the air plate assembly 16 are closely fitted and can slide relative to each other. The function of the air plate pressure plate assembly 19 is to ensure that the riveting head assembly 11 can provide sufficient hot gas when riveting the aluminum-plastic cover. The function of the air plate assembly 16 is to be a transition component for hot gas to enter the interior of the riveting head assembly 11, ensuring that hot gas enters the riveting head assembly 11 when each riveting head assembly 11 rotates to the air plate pressure plate assembly 19. The heater assembly 24 includes an electric heating tube and a high-temperature resistant tube 25. One end of the high-temperature resistant tube 25 is connected to the air outlet 23 of the electric heating tube, and the other end of the high-temperature resistant tube 25 is fixed to the pneumatic tin bronze plate 21 through a quick-connect fitting of the air pipe 18. The high-temperature resistant tube 25 communicates with the air outlet 23. The function of the high-temperature resistant tube 25 is to provide a channel for hot gas to enter the riveting head assembly 11. The function of the riveting head assembly 11 is to receive the hot gas from the outside and to rivet the aluminum-plastic cover. The function of the heater assembly 24 is to heat the gas provided by the customer on site and, under pressure, deliver the hot gas to the forming head 14 at the end of the riveting head, thereby heating the aluminum-plastic cover. The riveting disc track 4 has a semi-circular arc structure, with both ends of the riveting disc track 4 being inclined. When the main shaft 6 drives the turntable 8 to rotate, the riveting disc track 4 drives the riveting head assembly 11 to move up and down relative to the riveting head seat 9.

[0020] Specifically, the rivet head seat 9 is provided with a copper sleeve, which is a hollow cylindrical structure. The rivet head assembly 11 includes a sleeve rod 12, a cavity 13, a forming head 14, and a deep groove ball bearing 15. One end of the first spring is fixedly connected to the sleeve rod 12, and the other end of the first spring is fixedly connected to the top of the copper sleeve. The sleeve rod 12 is provided with a cavity 13, and the air pipe 18 extends into the cavity 13. The forming head 14 is located at the bottom of the sleeve rod 12, and the output end of the air pipe 18 communicates with the forming head 14. The deep groove ball bearing 15 is provided on the top of the sleeve rod 12, and one side of the top of the sleeve rod 12 is fixedly connected to the turntable 8. The first spring provides the rivet head assembly 11 with the reset power. The deep groove ball bearing 15 is used to cooperate with the riveting disc track 4. By means of the irregular structure of the riveting disc track 4, the rivet head assembly 11 is driven to move up and down.

[0021] The turntable 8 is located between the columns 2 and is located above the frame 1. The motor 5 and the heater assembly 24 are located inside the frame 1.

[0022] Specifically, the rotating base 10 includes an arc-shaped strip, wherein the outer circumference of the arc-shaped strip is provided with cover receiving and releasing cavities at equal intervals, the cover receiving and releasing cavities being used to receive and accommodate the aluminum-plastic cover.

[0023] The riveting mechanism also includes a feeding vibratory plate and a discharging vibratory plate. The feeding vibratory plate has a baffle at its conveying channel. The baffle is used to transfer the aluminum-plastic cap on the feeding vibratory plate to the cap receiving cavity. The discharging vibratory plate is used to remove the aluminum-plastic cap from the cap receiving cavity. The feeding and discharging vibratory plates are existing technologies and will not be described in detail here.

[0024] Specifically, the riveting disc track 4 includes an inclined section 26 and a flat section 27. When the turntable 8 rotates, the deep groove ball bearing 15 of the riveting head assembly 11 contacts the inclined section 26, and the bottom height of the riveting disc track 4 gradually decreases, causing the riveting head assembly 11 to move downward. When the deep groove ball bearing 15 contacts the flat section 27, the forming head 14 contacts the aluminum-plastic cover in the cover receiving and discharging cavity.

[0025] Among them, the air outlet 23 has a curved arc structure, and the center of the air outlet 23 is set to coincide with the center of the connecting hole 17. When the air plate assembly 16 rotates with the main shaft 6, the air outlet 23 of both cooperates with the connecting hole 17 to realize the delivery of hot gas, thereby realizing the heating of the punching riveting head assembly 11.

[0026] The frame 1 has a conduit 28 on one side, and the high-temperature resistant tube 25 is placed inside the conduit 28. The lower part of the conduit 28 is connected to the interior of the frame 1, and the upper part of the conduit 28 is connected to the top cover 3.

[0027] The working principle of this device is as follows: The heater assembly 24 heats the gas delivered from the air compressor via an electric heating tube. The heated gas is then transported along the high-temperature resistant tube 25 to the air plate pressure plate assembly 19 inside the riveting disc 7. The riveting disc 7 rotates under the drive of the motor 5. After the air outlet 23 is connected to the connecting hole 17, the gas in the air plate pressure plate assembly 19 can smoothly enter the air plate assembly 16. The heated gas enters the air pipe 18 of the corresponding punching head assembly 11 on the air plate assembly 16 along the high-temperature resistant tube 25, which heats the punching head assembly 11. At the same time, the punching head assembly 11 rotates to the guide rail of the large top cover 3 under the drive of the riveting disc 7. The punching head begins to press down to punch and rivet the aluminum-plastic cover until it is riveted. Then, it enters the next process under the drive of the turntable 8.

[0028] The present invention can also replace the air plate assembly 16 and air plate pressure plate assembly 19 in the riveting disc 7 with a slip ring electric heating structure to complete the riveting of the aluminum-plastic cover. The disadvantage is that this heating method consumes a lot of electricity, and the control process is complicated. There are many wires that need to be connected. If any wire has a problem, the maintenance difficulty will increase, and there is a risk of leakage.

[0029] The above are merely preferred embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art, all of which fall within the protection scope of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
