[0026] Example:

[0027] See also Figure 1-3 A rod feeding mechanism for a centerless lathe comprises a feeding rack 1, the upper end of the feeding rack 1 is fixedly connected to a plurality of evenly distributed bases 2, and a feeding roller 3 is rotatably connected inside the base 2, a feeding motor 4 is installed at the front end of the plurality of bases 2, and the output end of the feeding motor 4 is connected to the feeding roller 3, a rod body 12 is placed between the outer ends of the plurality of feeding rollers 3, a containing frame 5 is fixedly connected to the right end of the feeding rack 1, and a cleaning cover 6 in close contact with the containing frame 5 is provided inside the containing frame 5, a feeding opening 7 is opened at the left and right ends of the cleaning cover 6, and the right end of the rod body 12 passes through a pair of feeding openings 7 in turn and extends to the outside of the cleaning cover 6, a brushing cleaning mechanism 10 is installed between the inside of the cleaning cover 6 and the outer end of the rod body 12, and a suction and collection mechanism 11 is installed on the containing frame 5.

[0028] During use of the present scheme, multiple feeding motors 4 are started to drive multiple feeding rollers 3 to rotate respectively, and the rotation of multiple feeding rollers 3 drives the rod body 12 to move toward the cleaning cover 6. At the same time, a pair of sliding rod cylinders 9 drives the cleaning cover 6 to move up and down along the inner wall of the accommodating frame 5, so that the feeding port 7 corresponds to the rod body 12, so that the rod body 12 passes through the feeding port 7 and enters the cleaning cover 6. As the rod body 12 continues to move, the right end of the rod body 12 passes through the feeding port 7 on the left and enters the cleaning cover 6. At the same time, the lifting cylinder 1001 in the brushing cleaning mechanism 10 drives the movable brush body 1002 to move downward and approach the fixed brush body 1003 until the distance between it and the fixed brush body 1003 is less than the diameter of the rod body 12 and stops moving. Then the rod body 12 moves to the right side with the rolling assistance of multiple auxiliary guide rollers 1004 on the left, and contacts with the movable brush body 1002 and the fixed brush body 1003, so as to realize the use of the movable brush body 1002 and the fixed brush body 1003 during the movement. The contact friction between the brush body 1002 and the fixed brush body 1003 and the surface of the rod body 12 cleans the dust and iron filings attached to the surface of the rod body 12, and during the brushing and cleaning process of the movable brush body 1002 and the fixed brush body 1003, the air suction machine 1101 in the suction collection mechanism 11 works, driving the air suction pipe 1102 and the air suction bucket 1103 to suck air downward, so that the air flows from top to bottom, causing the dust and debris dropped by the brushing to move downward with the air and fall into the air permeable partition 1104 The dust and iron filings attached to the surface of the rod body 12 are cleaned and collected, and then the cleaned rod body 12 continues to move to the right with the assistance of multiple auxiliary guide rollers 1004 on the right, passes through the feeding port 7 on the right, and enters the centerless lathe. After the rod body 12 is cleaned, its surface remains clean, which can prevent it from carrying dust and iron filings to the centerless lathe, thereby avoiding affecting the processing of the rod body 12 by the centerless lathe and ensuring its processing effect.

[0029] See also Figure 1-2 The rear end of the accommodating frame 5 is fixedly connected with a connecting plate 8, and a pair of slide rod cylinders 9 are installed on the upper end of the connecting plate 8, and the output ends of the pair of slide rod cylinders 9 are fixedly connected with the rear end of the cleaning cover 6.

[0030] During use of this solution, the sliding rod cylinder 9 can drive the cleaning cover 6 to move up and down, and drive the feeding port 7 to adjust the height accordingly according to the position of the rod body 12, so that the feeding port 7 corresponds to the rod body 12, so that the rod body 12 can pass through the feeding port 7 and enter the cleaning cover 6.

[0031] See also Figure 3The brushing cleaning mechanism 10 includes a lifting cylinder 1001 installed on the top inner side of the cleaning cover 6, and a movable brush body 1002 is fixedly connected to the output end of the lifting cylinder 1001. A fixed brush body 1003 is fixedly connected between the inner walls of the cleaning cover 6, and the fixed brush body 1003 is located at the lower side of the movable brush body 1002. A plurality of auxiliary guide rollers 1004 are rotatably connected between the inner walls of the cleaning cover 6, and the plurality of auxiliary guide rollers 1004 are respectively located on the left and right sides of the fixed brush body 1003.

[0032] During use of this solution, after the rod body 12 enters the cleaning cover 6, the lifting cylinder 1001 drives the movable brush body 1002 to move downward, approaching the fixed brush body 1003, until the distance between it and the fixed brush body 1003 is less than the diameter of the rod body 12 and then stops moving, so that the movable brush body 1002 and the fixed brush body 1003 are in contact with the surface of the rod body 12 being transported, and the friction generated during the movement brushes the dust and iron filings attached to the surface of the rod body 12, causing them to fall from the surface of the rod body 12, thereby cleaning the dust and iron filings attached to the surface of the rod body 12.

[0033] See also Figure 1-3 The suction and collection mechanism 11 includes an exhaust fan 1101 installed on the right end of the containing frame 5, an exhaust pipe 1102 is embedded in the inner wall of the containing frame 5, and the exhaust pipe 1102 is connected to the exhaust fan 1101, and the upper end of the exhaust pipe 1102 is fixedly connected to an exhaust hopper 1103, the front end of the containing frame 5 is threadedly connected to a sealing plate 1105, and the rear end of the sealing plate 1105 is fixedly connected to a breathable partition 1104, a through opening is opened at the front end of the containing frame 5, and the breathable partition 1104 passes through the through opening and extends to the inside of the containing frame 5, the left and right ends of the breathable partition 1104 are slidably connected to the inner wall of the containing frame 5, and the breathable partition 1104 is located on the upper side of the exhaust hopper 1103.

[0034] During use of the present solution, after the dust and iron filings on the surface of the rod body 12 are cleaned by brushing and fall off the surface of the rod body 12, the vacuum fan 1101 works, driving the vacuum pipe 1102 and the vacuum bucket 1103 to draw air downward, causing the air to flow from top to bottom, prompting the dust and debris brushed off to move downward with the air and fall onto the breathable partition 1104 for collection, thereby collecting the dust and iron filings attached to the surface of the rod body 12. After the collection is completed, the sealing plate 1105 can be driven to move forward through a detachable threaded connection, causing the breathable partition 1104 to carry the collected dust and iron filings to move forward for discharge, so that the staff can clean the dust and iron filings.

[0035] See also Figure 3The left and right ends of the breathable partition 1104 are fixedly connected with sliders 11041, and the inner wall of the containing frame 5 is opened with a pair of left-right symmetrical slide grooves 11042, and the pair of slide grooves 11042 are both connected to the front side of the containing frame 5, and the slider 11041 is located in the slide groove 11042 and is slidably connected thereto.
