[0024] The feeding component includes a V-shaped groove 2 and a positioning tube 9. The V-shaped groove 2 is fixedly installed on the front surface of the feeding table 1. One end of the side surface of the V-shaped groove 2 is fixedly installed with a positioning tube 9 through a connecting rod. A strip-shaped opening is formed through the bottom surface of the V-shaped groove 2, and a feeding auxiliary component is arranged on the inner wall of the strip-shaped opening.

[0025] According to the overall structure of the device, after the material pipe is fed into the rolling groove 8, the material pipe will roll to the back of the stopper 13 and be arranged one by one due to gravity. During feeding, the push block 12 on the top surface of the push block 12 is driven by the second electric push rod 11 to lift the material pipe on the top surface of the push block 12, so that it can cross the stopper 13 and enter the V-shaped groove 2. During this process, due to the setting of the anti-slip pad 16 and the buffer inclined block 15, the material pipe will slowly roll down from the buffer inclined block 15 to prevent the material pipe from rolling out of the V-shaped groove 2 when it rolls to the inner wall of the V-shaped groove 2 due to excessive impact. When the material pipe is fed to the inner wall of the V-shaped groove 2, the arc surface of the material pipe will be placed on the arc surface of the first roller 7. At this time, the first electric push rod 5 on the connecting frame 3 drives the mounting frame 4 to move downwards. After the arc surface of the second roller 10 fits with the arc surface of the material pipe, the two second rollers 10 are driven to rotate by the drive motor 6, so that the material pipe can be transported to the positioning pipe 9 by the first roller 7 and the second roller 10, and enter the feeding port of the thread rolling machine through the positioning pipe 9 for feeding. When transporting material pipes of different lengths, there is no need to change the position of the mounting frame 4, and no additional space will be occupied.

[0026] As Figure 2 shown, the feeding auxiliary component includes a connecting shaft 14 and a first roller 7. A plurality of connecting shafts 14 are fixedly installed on the inner wall of the strip-shaped opening of the V-shaped groove 2. A connecting hole is formed through the middle of the front surface of the first roller 7, and the first roller 7 is sleeved on the connecting shaft 14 through the connecting hole.

[0027] Through the arranged connecting shaft 14 and the first roller 7, the material pipe fed into the V-shaped groove 2 will be attached to the arc surface of the first roller 7.

[0028] As Figure 1 shown, the driving component includes a connecting frame 3, a mounting frame 4 and a first electric push rod 5. Connecting frames 3 are fixedly installed on the front surface of the feeding table 1. A mounting opening is formed through the top surface of the connecting frame 3, and the first electric push rod 5 is fixedly installed on the inner wall of the mounting opening. The top surface of the movable rod of the first electric push rod 5 is fixedly connected with the mounting frame 4. An opening is formed through the top surface of the mounting frame 4, and the opening is located directly above the V-shaped groove 2. A driving auxiliary component is arranged on the inner wall of the opening of the mounting frame 4. The driving auxiliary component includes a drive motor 6 and a second roller 10. A plurality of shaft seats are fixedly installed on the front inner wall and the back inner wall of the opening of the mounting frame 4, and a rotating shaft is movably connected between two shaft seats. The arc surface of the rotating shaft on the inner wall of the mounting frame 4 is fixedly installed with the second roller 10. The drive motor 6 is fixedly installed on the front surface of the mounting frame 4, and the output end penetrates through the mounting frame 4 and the shaft seat and is fixedly connected with one end of one of the rotating shafts. The rotating shafts on the inner wall of the mounting frame 4 all penetrate through the shaft seat and the back surface of the mounting frame 4, and are all fixedly connected with belt pulleys. The belt pulleys are connected by a belt.

[0029] Through the provided connecting frame 3, mounting frame 4, first electric push rod 5, driving motor 6, and second roller 10, the first electric push rod 5 on the connecting frame 3 drives the mounting frame 4 to move downward. After the arc surface of the second roller 10 fits with the arc surface of the material pipe, the driving motor 6 drives the two second rollers 10 to rotate, so that the material pipe can be transported by the first roller 7 and the second roller 10 to the positioning pipe 9.

[0030] As Figures 3-4 shown, the feeding assembly includes a second electric push rod 11 and a push block 12. Installation grooves are formed in the inner wall of the rolling groove 8, and the second electric push rod 11 is fixedly installed at both ends of the inner wall of the installation groove. The top surface of the movable rod of the second electric push rod 11 is fixedly installed with the push block 12, and when the second electric push rod 11 is fully retracted, the push block 12 partially fits with the installation groove. The limiting assembly includes a stop block 13, a buffer inclined block 15, and an anti-slip pad 16.

During feeding, the second electric push rod 11 drives the push block 12 to lift the material pipe on the top surface of the push block 12, so that it crosses the stop block 13 and enters the V-shaped groove 2. During this process, due to the settings of the anti-slip pad 16 and the buffer inclined block 15, the material pipe will slowly roll down from the buffer inclined block 15, preventing the material pipe from rolling out of the V-shaped groove 2 when it rolls onto the inner wall of the V-shaped groove 2 due to excessive impact.

[0032] Working principle: After the material pipe is fed into the rolling groove 8, the material pipe will roll to the back of the stop block 13 and be arranged one by one due to gravity.

During this process, due to the settings of the anti-slip pad 16 and the buffer inclined block 15, the material pipe will slowly roll down from the buffer inclined block 15, preventing the material pipe from rolling out of the V-shaped groove 2 when it rolls onto the inner wall of the V-shaped groove 2 due to excessive impact. When the material pipe is fed to the inner wall of the V-shaped groove 2, the arc surface of the material pipe will be placed on the arc surface of the first roller 7. At this time, the first electric push rod 5 on the connecting frame 3 drives the mounting frame 4 to move downward. After the arc surface of the second roller 10 fits with the arc surface of the material pipe, the driving motor 6 drives the two second rollers 10 to rotate, so that the material pipe can be transported by the first roller 7 and the second roller 10 to the positioning pipe 9, and then enters the feeding port of the rolling machine through the positioning pipe 9 for feeding.
