Two left and right supporting ridges 9 are provided on the top of the rolling base plate 7. The supporting ridges 9 extend in the front-to-back direction, and the rod 24 is slidably supported by the top surfaces of the two supporting ridges 9. By providing the supporting ridges 9 to support the rod 24 in a slidable manner, the contact area between the rod 24 and the rod 24 is reduced, and the friction is reduced, so that the rod 24 is easy to roll. Two guide guard plates 8 are respectively slidably arranged on the rolling base plate 7, and the two guide guard plates 8 are driven to move closer to or farther from each other in the left and right directions by the adjustment mechanism to adjust the width of the rolling slideway; the bar material placement seat 4 is located in front of the rolling slideway, and a placement groove 10 for placing the bar material 24 is provided on the top of the bar material placement seat 4. The bottom surface of the placement groove 10 is an inclined surface with a lower front and a higher rear, and the rear end of the placement groove 10 is open, and the front end of the placement groove 10 is provided with a material blocking protrusion 11 protruding upward. The rolling frame 3 is provided with a detection sensor for detecting whether there is a bar material 24 in the placement groove 10 of the bar material placement seat 4, and the detection sensor can be a diffuse reflection photoelectric sensor.

[0026] The adjustment mechanism includes a lead screw 12 and two nut seats 13. The lead screw 12 is rotatably mounted below the rolling base plate 7 and extends in the left-right direction. The left and right ends of the lead screw 12 are rotatably mounted on the left and right bearing seats 15 below the rolling base plate 7. One end of the lead screw extends out of the rolling base plate 7 and is provided with an adjustment guide wheel 14.

The sliders 16 at the bottoms of the two guide guard plates 8 are respectively fixedly connected with the two nut seats 13. The lead screw 12 is driven to rotate by rotating the adjustment guide wheel 14, and the lead screw 12 then drives the two nut seats 13 that match the two threaded sections with opposite rotation directions to move in the opposite direction in the left-right direction, thereby realizing the adjustment of the spacing between the two guide guard plates 8 to meet the feeding requirements of rods 24 of different lengths.

[0027] Guide assemblies are provided on both the front and rear sides of the lead screw 12, each guide assembly includes a guide shaft 18 and two guide sleeves 19. The guide shaft 18 is fixedly mounted below the rolling base plate 7 and extends in the left and right directions. The two guide sleeves 19 are respectively slidably mounted on the guide shaft 18, and the tops of the two guide sleeves 19 are respectively fixedly connected to the bottoms of the two guide guard plates 8 through connecting plates 20. The bottom of the guide guard plate 8 is provided with a mounting flange 21 extending horizontally outward, and the slider 16 and the connecting plate 20 are both connected to the bottom of the mounting flange 21 of the guide guard plate 8. The guide sleeves 19 of the two sets of guide assemblies are slidably matched with the guide shaft 18 to guide the left and right movement of the two guide guard plates 8, thereby ensuring the smooth movement of the two guide guard plates 8.

[0028] A material ejection avoidance hole 22 is provided at the front end of the rolling base plate 7, and a material ejection assembly is provided on the frame 1 below the part located at the material ejection avoidance hole 22. The material ejection assembly includes a material ejection rod 23 that can be lifted and lowered, and the material ejection rod 23 extends upward from the material ejection avoidance hole 22 to eject the bar material 24 in the rolling slideway upward and roll it into the placement groove 10 of the bar material placement seat 4. The material ejection assembly also includes a material ejection frame 25 and a material ejection cylinder 26. The material ejection frame 25 is fixedly mounted on the frame 1, and the material ejection cylinder 26 is mounted at the bottom of the material ejection frame 25. The piston rod of the material ejection cylinder 26 extends upward and connects to the material ejection cross plate 27. Two material ejection rods 23 are provided on the material ejection cross plate 27. The piston rod of the material ejection cylinder 26 is extended and retracted to drive the two material ejection rods 23 to rise and fall, thereby realizing the lifting or release of the bar material 24. The ejection frame 25 is a rectangular frame, and the ejection cylinder 26 is installed on the bottom plate of the rectangular frame. The piston rod of the ejection cylinder 26 extends into the inner cavity of the rectangular frame and is connected to the ejection cross plate 27. Two guide sleeves 28 are provided on the top plate of the ejection frame. The two ejection rods 23 extend upward from the two guide sleeves 28 respectively. The two ejection rods 23 are guided to rise and fall by the two guide sleeves 28, thereby ensuring the smooth and stable lifting of the ejection rods 23 and ensuring its normal ejection operation.

[0029] During operation, the handle of the adjusting guide wheel 14 is first used to drive the adjusting guide wheel 14 to rotate, thereby adjusting the distance between the two guide guard plates 8 to adjust the width of the rolling slideway to match the length of the bar 24 to be loaded. Then, multiple bars 24 are placed on the rolling slideway in sequence, so that the length of the bars 24 is along the left and right directions, and the two ends of the bars 24 are guided by the left and right guide guard plates 8; and because the rolling slideway is arranged obliquely, the bars 24 can automatically roll to the front end of the rolling slideway under the action of gravity. The detection sensor detects whether there is a bar 24 in the placement slot 10 of the bar placement seat 4. When it is detected that there is no bar 24 in the placement slot 10 of the bar placement seat 4, the ejection cylinder 26 is activated, and the piston rod of the ejection cylinder 26 extends upward, and the two ejection rods 23 are ejected upward, and the bar 24 at the front end of the rolling slide is lifted and rolled forward into the placement slot 10 of the bar placement seat 4. Since the bottom surface of the placement slot 10 is an inclined surface with a low front and a high back, the bar 24 will automatically roll to the front end of the placement slot 10 and be blocked by the blocking protrusion 11; at this time, the detection sensor detects that there is a bar 24 in the placement slot 10 of the bar placement seat 4, and the piston rod of the ejection cylinder 26 retracts downward, and the bar 24 in the rolling slide automatically moves forward by one material level. Then, the bar 24 can be taken away from the placement slot 10 of the bar placement seat 4 by the robot's manipulator or other peripheral mechanisms, and loaded onto the material table of the medium frequency heating furnace. After the bar material 24 is taken away, the ejection cylinder 26 continues the ejection operation and enters the next cycle. The material is replenished in time according to the amount of bar material 24 in the rolling slideway manually to ensure the continuity of the feeding work.

[0030] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
