[0035] The present invention will be further explained below with reference to the accompanying drawings and specific embodiments. It should be understood that the following specific embodiments are only used to illustrate the present invention and are not intended to limit the scope of the present invention.

[0036] As shown in the figure, the feeding mechanism of the small and medium-sized round tube outer circle polishing machine of this utility model includes a support frame 1, a translation device, a pressing device, a feeding device and a storage device.

[0037] The translation device includes a row of fixed wheel frames 2, a row of movable wheel frames 3, a lifting frame 4, a cylinder 5, and a cylinder 6. The lifting frame 4 is movably mounted on the support frame 1. The fixed wheel frames 2 are fixed on the lifting frame 4, and the movable wheel frames 3 are movably mounted on the lifting frame 4. The fixed wheel frames 2 and the movable wheel frames 3 are arranged parallel to each other. The rollers 7 on the fixed wheel frames 2 and the movable wheel frames 3 are horizontally inclined at 10-40°. Cylinders 5 and 6 are mounted on the support frame 1. Cylinder 5 is connected to the lifting frame 4, and cylinder 6 is connected to the movable wheel frames 3. A sensor 8 is provided at the tail end of the fixed wheel frame 2. During operation, the round tube coming out of the polishing machine can move forward along the inclined rollers. Cylinder 6 can make the movable wheel frame move horizontally to adjust the distance between the two rows of rollers 7. The sensor 8 can output a signal to limit the movement position of the round tube 26.

[0038] The clamping device includes a motor mounting bracket 9, a rotary motor 10, and a cylinder 11. The motor mounting bracket 9 is L-shaped and installed on the side of the support frame 1. A slider 12 is provided on the vertical inner side of the motor mounting bracket 9. The rotary motor 10 is mounted on the slider 12. The output end of the rotary motor 10 is connected to a disc elastic pressure head 13. The disc elastic pressure head 13 is located above the fixed wheel frame 2 and the movable wheel frame 3. A movable seat 14 is provided on the bottom surface of the motor mounting bracket 9. The cylinder 11 is connected to the movable seat 14, which allows the disc elastic pressure head 13 to move left and right to ensure that the radial center point of the round tube 26 is pressed. After adjusting the position, the cylinder 5 adjusts the height of the lifting frame to ensure that the disc elastic pressure head 13 just presses the round tube, ensuring that the round tube enters the unloading mechanism horizontally and straight after coming out of the polishing machine.

[0039] The discharge device includes a lifting frame 15, a fourth cylinder 16, and a fifth cylinder 17. The fifth cylinder 17 is vertically connected to the lifting frame 15, and the fourth cylinder 16 is located on the side of the lifting frame 15. The two lifting frames 15 are located below the fixed wheel frame 2 and the movable wheel frame 3.

[0040] The storage device includes a receiving rack 18, a receiving bracket 19, a retractable baffle 20, a lifting motor 21, and a transmission device 22. The receiving rack 18 is located on the outside of the support frame 1, the receiving bracket 19 is located on the support frame 1 and extends toward the receiving rack 18, the retractable baffle 20 is movably located inside the receiving rack 18, the lifting motor 21 is connected to the retractable baffle 20 through the transmission device 22, and a sensor 23 is provided on the side of the receiving rack 18.

[0041] The support frame 1 of this utility model is a frame structure welded from angle steel and iron bars, which is stable and reliable. An adjusting nut 24 is provided at the bottom to ensure the base remains horizontal. During operation, first adjust cylinder 2 6 to move the movable wheel frame 3 horizontally, adjusting the distance between the two rows of rollers 7. Simultaneously, adjust the height of the lifting frame 4 via cylinder 1 5 to ensure the round tube 26 can fall between the fixed wheel frame 2 and the movable wheel frame 3. The polished round tube slowly enters between the fixed wheel frame 2 and the movable wheel frame 3. At this time, the pressure head inside the polishing machine is still driving the round tube to rotate. When the head of the round tube moves below the disc elastic pressure head 13, the pressure head inside the polishing machine will stop, and the disc elastic pressure head 13 will drive the round tube to rotate. The position of the disc elastic pressure head 13 is driven horizontally by cylinder 3 11 to ensure it presses down on the center of the round tube. When the round tube reaches its end, sensor 1 8 detects a signal and outputs a signal, the rotary motor 10 stops rotating, and the round tube 26 stops moving. At this time, adjust cylinder 2 6, the fixed wheel frame 2... Separated from the movable wheel frame 3, the lifting frame 4 descends, causing the round tube to fall onto the lifting frame 15 (the lifting frame 15 is located below the fixed wheel frame 2 and the movable wheel frame 3). At this time, cylinder 5 17 starts and drives the lifting frame 15 to rise. After reaching the preset height, cylinder 4 16 starts and pushes the lifting frame 15 to move towards the receiving frame 18. After reaching the preset position, the lifting frame 15 descends, and the round tube 26 falls onto the receiving bracket 19. Since the rear half of the upper surface of the receiving bracket 19 is inclined backward and downward, the round tube 26 rolls down along the inclined surface into the receiving frame 18 (initially, the height difference between the receiving bracket 19 and the retractable baffle 20 is not large, so the round tube will not be deformed when it falls). When it is sensed that the round tube is laid flat for more than one layer, the lifting motor 21 drives the retractable baffle 20 to descend (the height difference becomes larger and larger), and finally they are transported away together.

[0042] This utility model has a shock-absorbing rubber layer on the surface of the retractable baffle 20, which plays a protective role when the round tube falls.

[0043] The transmission device 22 of this utility model includes a reducer, a bearing housing, a gear, and a chain. The lifting motor is connected to the reducer, the gear is mounted on the bearing housing, the reducer is connected to the chain through the gear, and the chain is connected to the lowerable baffle 20 through the gear.

[0044] The roller 7 of this utility model has an arc-shaped adjustment hole 25 on its fixed support, such as... Figure 7As shown, the angle can be adjusted according to the diameter of the pipe to ensure that the pipe can move forward smoothly.

[0045] The lifting frame 15 described in this utility model has a V-shaped structure, which can ensure that the circular tube is in the center position.

[0046] This utility model features fully automated operation from material discharge to alignment and sorting, reducing the workload of workers and improving work efficiency. Moreover, it can be adjusted in all directions, has a scientific structure, is easy to use, and can be used for small and medium-sized round tubes of 16-50mm, making it widely applicable.

[0047] It should be noted that the above content merely illustrates the technical concept of this utility model and cannot be used to limit the scope of protection of this utility model. For those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and all such improvements and modifications fall within the scope of protection of the claims of this utility model.
