[0017] As Figs. 1 to 3As shown, this utility model relates to a can feeding mechanism of an automatic steel bucket welding machine, including a can platform main frame. A tension handwheel 1 is provided on the side of the main frame. A can guide 2 is provided on the main frame, including an arc-shaped can guide 201. Multiple pulley rods 203 are provided at one end of the arc-shaped can guide 201. In this design, five pulley rods 203 are used. Adjusting rods 204 are provided between the multiple pulley rods 203. Adjusting screws 202, locking screws 205, and angle locking screws 206 are connected between the arc-shaped can guide 201, the pulley rods 203, and the adjusting rods 204 for easy fixing and adjustment. An upper can guard 3 is provided between the ends of the main frame. A chain claw 5 is installed on the upper can guard 3. A push claw 6 is provided on one side of the chain claw 5, and a corner sprocket 7 is provided on one side of the push claw 6. A photoelectric sensor 8 is provided at the other end of the upper can guard 3. The stopping position of the can delivery is about 30mm away from the photoelectric sensor 8. A handle 4 is provided on the outer periphery of one end of the upper protective can 3. Multiple sizing gauge protective cans 9 are provided on the upper protective can 3. An encoder 10 is provided on the outside of the sizing gauge protective can 9. A tension sprocket 11 fixed to the main frame of the can delivery platform is provided on the outside of the encoder 10. A pressure block 12 and a positioning block 13 fixed to the main frame of the can delivery platform are provided on the outside of the upper protective can 3. An overload sensor 14 is provided on the lower half of the side of the main frame of the can delivery platform. A safety clutch 16 is provided at one end of the overload sensor 14. A drive shaft 17 is provided above the safety clutch 16. An inner arc plate 18 and an outer arc plate 19 are provided on the upper half of the main frame of the can delivery platform. A round pressure can 21 is installed on the upper half of the main frame of the can delivery platform. The inner arc plate 18 and the outer arc plate 19 form a semi-circular ring. An adjustment block 20 is provided on the semi-circular ring.

[0018] In this embodiment of the invention, the can feeding is controlled by the chain claw 5 and the encoder 10, which control the feeding position each time. One revolution of the encoder 10 corresponds to one can feeding. An external touchscreen is installed, and the on / off angles of the touchscreen are calculated by the encoder 10 based on the overall machine movement. 0° is located at the highest point of the corner sprocket 7. The angle of the chain claw 5 is set according to the can height.

[0019] Adjustment and interchangeability of can guide 2: Can guide 2 consists of an arc can guide 201 and a pulley rod 203. It is an interchangeable can guide 2 with the same diameter as the sizing gauge. When replacing can guide 2, pull out the screw on the pressure block 12 from the back of the can feeding platform, loosen the upper adjusting screw 202 of the arc can guide 201 and adjust it to the height of the can after it is round. This will support the can body and prevent it from falling off the guide groove. The can body should not be too tight or too loose. If it is adjusted too high, the can body will be deformed or scratched. If it is adjusted too low, the can body will fall off the guide groove and cause the can to jam.

[0020] After the tank channel 2 is adjusted, the round pressure tank 21 is pressed against the tank body. The touch screen is operated to feed the tank. The chain claw 5 feeds the tank into the five pulley rods 203. The outer area of ​​the pulley rod 203 is provided with Z-rod guide groove. The pulley rod 203 and the adjusting rod 204 can swing together to adjust the height. The tangent angle of the rollers on both sides of the pulley rod 203 hugs the tank body into a round shape and is in the center of the Z-rod guide groove. The tank is smoothly fed into the front sizing gauge tank 9. The tension of each group of pulley rods 203 should be such that the tank does not jam or fall out of the Z-rod guide groove.

[0021] Upper protective can 3: The upper protective can 3 consists of four pulley rods 203, two on each side, which hold the upper part of the can body tightly. The pulley rods 203 are fixed on the inner arc plate 18 and the outer arc plate 19. Loosening the screws of the adjusting block 20 can adjust the position of holding the can body. When the can is stuck, pull the handle 4 to lift the outer pulley rod 203 and the stuck can be easily removed.

[0022] Safety clutch 16: When the load on the can delivery chain claw 5 is too high (such as can jamming), the safety clutch 16 disengages from the drive. The overload sensor 14 detects the fault in the safety clutch 16 and the equipment automatically stops. At this time, the drive shaft 17 is twisted to reset the safety clutch 16. The red light on the overload sensor 14 goes out. After the fault is cleared, the touch screen can be used to reset it.

[0023] The safety clutch 16 is equipped with an adjusting nut 15. The torque of the safety clutch 16 can be adjusted by adjusting the nut 15. It should be noted that before turning the torque adjusting nut 15, the set screw 205 on its circumference should be loosened first.

[0024] The embodiments disclosed herein are preferred embodiments, but are not limited thereto. Those skilled in the art can readily grasp the spirit of this utility model based on the above embodiments and make different extensions and variations. However, as long as they do not depart from the spirit of this utility model, they are all within the protection scope of this utility model.
