Description

Technical Field

[0001] This invention relates to the field of automatic material feeding mechanism technology, specifically to an automatic material feeding mechanism for a double-head chamfering machine. Background Technology

[0002] The clamping mold and cutter head of the automatic double-head chamfering machine are ingeniously designed to ensure that the center line of the workpiece and the cutter head remains accurate and unchanged. It can complete the processing of the outer corner, inner corner and end face of seamless steel pipe in one uniform operation, ensuring accurate processing dimensions. Automatic feeding via vibratory feeder greatly improves production efficiency and saves manpower.

[0003] In existing technologies, the automatic feeding mechanism of a double-head chamfering machine requires a motor to push the material onto the slide plate, increasing costs. Furthermore, the material falling from the slide plate of the automatic feeding mechanism in the double-head chamfering machine generates significant impact, causing collisions between the falling material and the material placed on the slide plate, resulting in wear and tear. Therefore, we propose an automatic feeding mechanism for a double-head chamfering machine. Summary of the Invention

[0004] The purpose of this invention is to provide an automatic material feeding mechanism for a double-head chamfering machine to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] An automatic material feeding mechanism in a double-head chamfering machine includes a feeding device. Symmetrical pulleys are provided on the front side of the feeding device. One end of one of the pulleys is equipped with a motor, which is fixedly connected to the output shaft of the motor. A common conveyor belt is fitted onto both pulleys. Several abutment plates are fixedly connected to the surface of the conveyor belt. A push plate is abutted against one side of one of the abutment plates. A support rod is provided below the push plate. A circular groove is formed on the top surface of the support rod. A rotating groove is formed inside the support rod. A rotating column is rotatably connected to the circular groove. A fixing block is fixedly connected to the surface of the rotating column. The fixing block is located inside the rotating groove, and the rotating groove is rotatably connected to the fixing block. A sliding groove is formed on the inner wall of the rotating groove. An elastic component is provided in the sliding groove. A sliding plate is fixedly connected to the front side of the conveyor belt. A rectangular block is fixedly connected to the front side of the sliding plate. A cross-shaped rotating rod is rotatably connected to the rectangular block. Two symmetrical buffer components are provided at each of the four ends of the cross-shaped rotating rod.

[0007] Preferably, the elastic component includes a second spring, which is fixedly connected to the inner wall of the slide groove, and a slider is fixedly connected to the other end of the second spring, with the front side of the slider abutting against the fixed block.

[0008] Preferably, the buffer assembly includes a spring, which is fixedly connected to the end of the cross-shaped rotating rod.

[0009] Preferably, the front side of the second spring has an arc-shaped structure.

[0010] Preferably, one side of the rotating groove is an arc groove, and the radius of the arc groove is equal to the diameter of the fixing block.

[0011] Preferably, the width between every two of the abutments is equal to the width of the slide plate.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] 1. The automatic material feeding mechanism in this double-head chamfering machine, through the setting of a conveyor belt, a stop plate, a push plate, a fixed block and a slider, allows the other end of the push plate to push the material towards the slide plate through the cooperation of the stop plate and the conveyor belt, thus saving costs. Then, through the cooperation of the slider and the fixed block, the push plate can be returned to its original position to push the next material.

[0014] 2. The automatic material feeding mechanism in this double-head chamfering machine, through the setting of a sliding plate, a cross-shaped rotating rod and a spring, uses the spring to reduce the impact force of the material falling from the sliding plate, and then the rotation of the cross-shaped rotating rod to buffer the next material, thereby improving the accuracy of material processing.

[0025] Please see Figures 1-5 As shown, the present invention provides a technical solution:

[0026] An automatic material feeding mechanism in a double-head chamfering machine includes a feeding device 1. Symmetrical pulleys 2 are provided on the front side of the feeding device 1. One end of one pulley 2 is equipped with a motor 3. The pulley 2 is fixedly connected to the output shaft of the motor 3. A common conveyor belt 4 is fitted onto both pulleys 2. Several abutment plates 5 are fixedly connected to the surface of the conveyor belt 4. A push plate 6 is abutted against one side of one of the abutment plates 5. A support rod 7 is provided below the push plate 6. A circular groove 8 is formed on the top surface of the support rod 7. A rotating groove 9 is formed inside the support rod 7. A rotating column 10 is rotatably connected inside the circular groove 8. A fixing block 11 is fixedly connected to the surface of the rotating column 10. The fixing block 11 is located inside the rotating groove 9, and the rotating groove 9 is rotatably connected to the fixing block 11. A sliding groove 12 is formed on the inner wall of the rotating groove 9. An elastic component is provided inside the sliding groove 12. A sliding plate 13 is fixedly connected to the front side of the conveyor belt 4. A rectangular block 14 is fixedly connected to the front side of the sliding plate 13. A cross-shaped rotating rod 15 is rotatably connected to the rectangular block 14. Two symmetrical buffer components are provided at each of the four ends of the cross-shaped rotating rod 15.

[0027] Furthermore, the elastic component includes a second spring 17, which is fixedly connected to the inner wall of the slide 12. The other end of the second spring 17 is fixedly connected to a slider 18, the front side of which abuts against the fixed block 11. When the rotating column 10 starts to rotate, it will drive the fixed block 11 to rotate. Then, the fixed block 11 will contact the arc surface of the slider 18 and squeeze the slider 18, causing the slider 18 to squeeze the second spring 17 and move towards the slide 12. During this process, the rotation angle of the fixed block 11 is less than 90 degrees. When the abutment plate 5 at one end of the material releases the abutment from the push plate 6, the slider 18 will be rebounded by the second spring 17, and the arc surface of the slider 18 will contact one side of the fixed block 11. The slider 18 will squeeze the fixed block 11, causing the fixed block 11 to return to its original position, completing one cycle. This process avoids the need for a motor 3 to push the material onto the slide plate 13 in the automatic feeding mechanism of the double-head chamfering machine, which would increase costs.

[0028] Furthermore, the buffer assembly includes spring 16, which is fixedly connected to the end of the cross-rotor 15. When the material falls from the slide plate 13, the material comes into contact with the corresponding two springs 16, and the material will squeeze the corresponding two springs 16 to reduce the impact force of the fall. At the same time, the cross-rotor 15 rotates under the impact force of the material until one end of the cross-rotor 15 corresponding to the material is parallel to the slide plate 13, and then buffers the impact force of the next material. This process avoids the large impact force generated when the material falls from the slide plate 13 of the automatic feeding mechanism in the double-head chamfering machine, which would cause the falling material to collide with the material placed on the slide plate 13 and cause wear between the materials.

[0029] Furthermore, the front side of the second spring 17 has an arc structure, which allows the second spring 17 to move accordingly when it is compressed.

[0030] Furthermore, one side of the rotating groove 9 is an arc groove with a radius equal to the diameter of the fixed block 11, allowing the fixed block 11 to rotate inside the rotating groove 9 and press against the arc surface of the slider 18. Then, the slider 18 presses against the second spring 17 and moves towards the sliding groove 12. During this process, the rotation angle of the fixed block 11 is less than 90 degrees. When the abutment plate 5 at one end of the material releases its abutment from the push plate 6, the slider 18 will be rebounded by the second spring 17, and the arc surface of the slider 18 will contact one side of the fixed block 11. The slider 18 will press against the fixed block 11, causing the fixed block 11 to return to its original position, completing one cycle. This process avoids the need for the motor 3 to push the material onto the slide plate 13 in the automatic feeding mechanism of the double-head chamfering machine, which would increase costs.

[0031] Furthermore, the width between each pair of abutments 5 is equal to the width of the slide plate 13, so that after being pushed by the pusher plate 6, the material can roll from between the two abutments 5 into the slide plate 13 for the next step of processing.

[0032] In this embodiment, the automatic feeding mechanism of the double-head chamfering machine is activated when the feeding device 1 and motor 3 are started. The feeding device 1 then sequentially feeds the material between the two corresponding abutment plates 5. The output shaft of motor 3 then drives one of the pulleys 2 to rotate. The pulley 2 then drives the conveyor belt 4 to transport the material towards the slide plate 13 until one end of the abutment plate 5 contacts one end of the push plate 6. At this point, the abutment plate 5 presses against the push plate 6, causing the push plate 6 to drive the rotating column 10 to rotate. The rotating column 10 then drives the fixed block 11 to rotate. The fixed block 11 then contacts the arc surface of the slider 18, and the fixed block 11 presses against the slider 18, causing the slider 18 to press against the second spring 17 and move towards the slide groove 12. During this process, the rotation angle of the fixed block 11 is less than 90 degrees. When the abutment plate 5 at one end of the material releases its contact with the push plate 6, the slider 18 is rebounded by the second spring 17, and the slide... The arc surface of block 18 will contact one side of fixed block 11, and slider 18 will press fixed block 11 to return fixed block 11 to its original position, completing one cycle. This process avoids the need for motor 3 to push the material onto slide plate 13 in the automatic feeding mechanism of the double-head chamfering machine, which would increase costs. After that, the material will fall from slide plate 13 until it contacts the corresponding two springs 16. The material will press the corresponding two springs 16 to reduce the impact force of the fall. At the same time, cross rod 15 will rotate under the impact force of the material until one end of cross rod 15 is parallel to slide plate 13, and then buffer the impact force of the next material. This process avoids the large impact force generated when the material falls from slide plate 13 of the automatic feeding mechanism in the double-head chamfering machine, which would cause the falling material to collide with the material placed on slide plate 13 and cause wear between the materials.
