DETAILED DESCRIPTION

[0021] In order to make the technical means, creative features, purposes and effects realized by the utility model more clear and easy to understand, the utility model is further described below in combination with the drawings and specific embodiments:

[0022] As Figs. 1-2 shown, the utility model provides a screw conveying type scrap iron feeding device, include: feeding device 1 and driving device 2, driving device 2 is located at one side of feeding device 1, and the rotating end of feeding device 1 is connected with the output end of driving device 2, and driving device 2 is used to drive the movement of scrap iron in feeding device 1, feeding device 1 includes: conveying pipe body 11, rotating assembly 12, intermediate bearing 13 and bearing adjusting device 14, conveying pipe body 11 is horizontally arranged, rotating assembly 12 penetrates conveying pipe body 11, rotating assembly 12 can rotate relative to conveying pipe body 11, intermediate bearing 13 is sleeved in rotating assembly 12, intermediate bearing 13 is connected with bearing adjusting device 14, bearing adjusting device 14 is movably installed on conveying pipe body 11, and bearing adjusting device 14 can adjust the relative position of intermediate bearing 13 in conveying pipe body 11.

[0023] When using, driving device 2 starts and drives rotating assembly 12 to rotate, along with the rotation of rotating assembly 12 to push scrap iron to move along the inner wall of conveying pipe body 11. After scrap iron enters conveying pipe body 11 from feed inlet 111, gradually moves to the direction of discharge port 112 under the push of rotating assembly 12. Intermediate bearing 13 is properly adjusted vertical position and horizontal position through bearing adjusting device 14, when scrap iron is uneven, ensures that rotating assembly 12 can stably and continuously rotate. Finally, scrap iron is conveyed to discharge port 112 and discharged, and the feeding process is completed.

[0024] The rotating assembly 12 comprises a rotating shaft 121 and a helical blade 122, the helical blade 122 is wrapped around the rotating shaft 121 and can be rotated in the conveying pipe body 11 by the rotating shaft 121. The helical blade 122 is divided into two sections, and the two sections of the helical blade 122 are located on both sides of the middle bearing 13. Since the rotating shaft 121 is in smooth contact with the middle bearing 13, the middle bearing 13 can guide the rotation of the rotating shaft 121, the rotating shaft 121 can rotate, and the helical blade 122 can move the iron filings when the rotating shaft 121 rotates, thereby realizing conveying.

[0025] The rotation of the rotating shaft 121 drives the helical blade 122 to rotate, and the helical blade 122 moves the iron filings along the helical track in the conveying pipe body 11 through the friction and thrust between the helical surface of the helical blade 122 and the iron filings.

[0026] As shown in Fig. 3 The bearing adjusting device 14 comprises a fixed seat 141, an adjusting rod 142, a sliding block 143 and a positioning block 144. The fixed seat 141 is installed on the surface of the conveying pipe body 11, the fixed seat 141 and the positioning block 144 are connected by bolts 145, and the fixed seat 141 and the positioning block 144 are both provided with sliding grooves 146.

[0027] The vertical position of the middle bearing 13 is adjusted by rotating the adjusting rod 142 relative to the sliding block 143, and the horizontal position of the middle bearing 13 is adjusted by sliding the adjusting rod 142 in the sliding groove 146, so that the rotating shaft 121 is always concentric with the center axis of the conveying pipe body 11, thereby reducing the deformation of the middle part of the rotating shaft 121 due to vibration during rotation.

[0028] Since the two ends of the rotating shaft 121 have been installed on the conveying pipe body 11 during installation, the rotating shaft 121 can rotate, the two-point line has been positioned for the rotating shaft 121, and therefore, in order to ensure that the middle bearing 13 can support the rotating shaft 121, the middle bearing is designed to be adjustable and the sliding block is movable, so that the positions of the two ends of the rotating shaft 121 and the position of the middle bearing are on a straight line, and the middle part of the rotating shaft 121 can be fully supported by the middle bearing.

[0029] The conveying pipe body 11 is provided with a feeding port 111 at one end away from the driving device 2, and is provided with a discharging port 112 at one end close to the driving device 2, and the feeding port 111 and the discharging port 112 are in communication with the conveying pipe body 11. The iron filings form a directional moving path in the conveying pipe body 11 from the feeding port 111 to the discharging port 112. The feeding port 111 is located at one end of the conveying pipe body 11 away from the driving device 2, facilitating the input of iron filings; the discharging port 112 is located at one end close to the driving device 2, facilitating the output of iron filings, thereby realizing efficient conveying of iron filings.

[0030] The conveying pipe body 11 is provided with mounting seats 113 at both ends, and the mounting seat 113 comprises a base 1131 and a mounting plate 1132, and the two ends of the conveying pipe body 11 are fixedly connected with the mounting plate 1132; the two mounting seats 113 are further provided with a supporting seat 114, and the supporting seat 114 is used for supporting the conveying pipe body 11. The mounting seat 113 and the supporting seat 114 jointly act to ensure that the conveying pipe body 11 remains stable during the conveying of iron filings, reducing vibration and displacement

[0031] The rotating shaft 121 is connected with a bearing ring 1133 at both ends through the mounting plate 1132, the bearing ring 1133 is fixed with the mounting plate 1132, and the rotating shaft can rotate relative to the mounting plate 1132 and the bearing ring 1133. The bearing ring 1133 is fixed on the mounting plate 1132 to provide stable support and positioning for the rotating shaft 121. The rotating shaft 121 can freely rotate in the bearing ring 1133 to ensure smoothness and stability during rotation.

[0033] The servo motor 21 is started, and the output end thereof is connected with the input end of the speed reducer 22 to transmit power to the speed reducer 22. After receiving the power from the servo motor 21, the speed reducer 22 reduces the rotating speed and increases the torque to transmit stable power to the rotating shaft 121 connected with the output end of the speed reducer 22. After receiving the power, the rotating shaft 121 starts to rotate, drives the spiral blade 122 to rotate, and pushes the iron filings to move in the conveying pipe body 11.

[0034] The feeding port 111 is in the form of a funnel, the upper end of the feeding port 111 is large, and the lower end of the feeding port 111 is small. The funnel-shaped feeding port 111 expands the feeding range, facilitating the collection and guidance of iron filings. The large upper end facilitates the simultaneous entry of a large amount of iron filings, and the small lower end concentrates the iron filings into the conveying pipe body 11, ensuring that the iron filings can enter the conveying pipe body 11 efficiently and uniformly, providing stable material input for subsequent spiral conveying.
