DETAILED DESCRIPTION

[0033] The present application is further described in detail below in conjunction with all the accompanying drawings.

[0034] The embodiment of the present application discloses a material receiving follower device for a pipe cutting machine.

[0035] Reference Figure 1 A material receiving follower device for a pipe cutting machine includes a frame 1, a lifting component 2, a supporting device 3 and a turning component 4.

[0036] Reference Figure 2 and Figure 3 , the lifting assembly 2 drives the flip assembly 4 and the support device 3 to rise and fall synchronously, playing the role of follow-up support when cutting pipes of different shapes, reducing the reduction of cutting accuracy caused by the swing of the pipe. At the same time, when the cutting machine cuts the pipe, the cutting machine needs to drive the pipe to rotate, especially the square pipe or special-shaped pipe. When rotating, the distance between the pipe and the support device changes, and the lifting assembly needs to be lifted and lowered at any time, so that the support device always abuts against the bottom of the pipe and supports the pipe. The lifting assembly 2 includes a lifting motor 21, a first diverter 22, a second diverter 23, a plurality of lifters 24 and a plurality of couplings 25. The lower end faces of the first diverter 22, the second diverter 23 and the lifter 24 are all connected to the frame 1. Multiple lifters 24 are evenly arranged on both sides of the frame 1 parallel to the pipe conveying direction to enhance the stability and stability of the support device 3 and realize the smooth lifting of the support device 3. A rotating shaft 26 is provided between two adjacent lifters 24 on one side of the pipe conveying direction, and both ends of the rotating shaft 26 are connected to the lifter 24 through a coupling 25. The first diverter 22 and the second diverter 23 each include an input end and two coaxial output ends, the axes of the input end and the output end are located in the same horizontal plane and are vertically arranged, the rotating shaft 327 of the lifting motor 21 is connected to the input end of the first diverter 22, and the output end of the first diverter 22 is connected to the input end of the second diverter 23 via a coupling 25, and then the two output ends of the second diverter 23 are respectively connected to an elevator 24, so that the function of using one lifting motor 21 to drive two rows of elevators 24 to lift and lower at the same time is achieved, thereby reducing the number of driving devices that drive the elevators 24 to lift and lower, and reducing production costs.

[0037] Reference Figure 4As a key component of the material receiving follower device, the elevator 24 is mainly composed of a housing 241, a worm wheel 242, a worm 243 and a lead screw 244. The lower end of the housing 241 is fixedly connected to the frame 1, and the two ends of the worm 243 extend out of the housing 241 and are rotatably connected to the housing 241 along its axis to ensure the stability of the transmission. The worm wheel 242 is meshed and connected with the worm 243, and is coaxially fixed with the lead screw to achieve accurate power transmission. The lead screw is rotatably connected to the housing 241 on the vertical axis and is threadedly connected to the frame 1, thereby achieving a precise lifting function. A rotating shaft 26 is provided between adjacent worms 243, which are connected by a coupling 25, thereby enhancing the stability and durability of the elevator 24. Due to the special structure of the worm wheel 242 and the worm 243, the elevator 24 has a self-locking performance, that is, when the worm wheel 242 stops rotating, the lead screw 244 will not fall automatically due to gravity or external force, thereby improving the safety of equipment operation. The lifting speed and position of the lead screw 244 can be adjusted by controlling the rotation speed and direction of the worm 243 to achieve precise lifting control.

[0038] Reference Figure 5 and Figure 6 The support device 3 includes a bracket 31, a driving assembly 32 and a plurality of conveying rollers 33. The driving assembly 32 drives the conveying rollers 33 to rotate, thereby smoothly conveying the pipe. The conveying rollers 33 are evenly arranged on the bracket 31 along the conveying direction of the pipe to ensure the smooth transmission of the pipe. A plurality of bearing seats 313 are provided at the upper end of the bracket 31. The two ends of the conveying rollers 33 are inserted into the bearing seats 313 and the conveying rollers 33 are rotatably connected with the bearing seats 313 along their own axes. The diameter of the conveying rollers 33 increases evenly from the middle to both sides along the direction of their own axes. For pipes of different shapes, especially non-circular or irregular shapes, the conveying rollers 33 whose diameters increase evenly from the middle to both sides along the axis direction of the conveying rollers 33 can better adapt to their bottom contours and ensure the stability of the pipes during the conveying and cutting process. The bracket 31 is made of a plurality of steel sections and a plurality of square tubes by welding or other fixing methods.

[0040] Reference Figure 1 and Figure 5 The flip assembly 4 is used to drop the cut pipe from the support device 3 to one side of the frame 1. Four flip assemblies 4 are provided to meet the sorting needs of pipes of different lengths and specifications. They are located above the bracket 31 and arranged along the pipe conveying direction.

The plurality of first flip plates 41 are arranged on the bracket along the pipe conveying direction. The first flip plates 41 and the conveying rollers 33 are staggered in the pipe conveying direction. The first connecting plate 42 is located between the rotation axis of the first flip plates 41 and the conveying rollers 33. The two first flip plates 41 farthest from each other in the pipe conveying direction in each flip assembly 4 are both provided with a first push rod 43 at the end away from the rotation of the bracket 31. A push ring 451 is sleeved on the outer side of one end of the first push rod 43. A flip cylinder 45 is fixedly connected below the push ring 451. A rotating seat 311 is provided on the bracket 31. The cylinder body of the flip cylinder 45 is rotatably connected to the rotating seat 311. The flip cylinder 45 can be used to drive the first flip plate 41 to flip, thereby realizing automatic unloading of pipes. When the pipes need to be unloaded, the flip cylinder 45 drives the first flip plate 41 to rotate, so that the pipes on the first flip plate 41 fall along the first flip plate 41 under the combined action of their own gravity, the inclination angle of the first flip plate 41 and the friction between the pipes and the first flip plate 41, thereby avoiding the problem that traditional pipe conveying devices need to convey the pipes to the outside of the device before unloading, reducing the use space of the equipment and speeding up the unloading rate.

[0042] Reference Figure 6 and Fig. 9Each flip assembly 4 further includes a plurality of second flip plates 46 and a plurality of second connecting plates 47. The number of the second flip plates 46 is the same as that of the first flip plates 41. Two adjacent second flip plates 46 are fixedly connected by the second connecting plate 47. The end of the second flip plate 46 away from the first flip plate 41 is rotatably connected to the bracket 31. The plurality of second flip plates 46 are arranged on the bracket along the pipe conveying direction. The second flip plates 46 are located between the first flip plate 41 and the conveying roller 33. The second connecting plate 47 is located at the end of the conveying roller 33 away from the first connecting plate 42. In the flip assembly 4, the two second flip plates 46 farthest from each other in the pipe conveying direction are both provided with a second push rod 48 at the end close to the first connecting plate 42. The first push rod 43 and the second push rod 48 have the same diameter and are coaxially arranged. A first supporting plate 44 for supporting the first flip plate 41 is provided below one end of the first push rod 43 away from the top ring 451.

A translation cylinder 312 is fixedly provided on the bracket 31. The telescopic end of the translation cylinder 312 is fixedly connected to the rotating seat 311. By providing a slide groove at the lower end of the rotating seat 311, the outer wall of the steel section abutting against the rotating seat 311 in the bracket 31 is fitted with the inner wall of the slide groove, so that the rotating seat 311 is slidably connected to the bracket 31 along the pipe conveying direction.

[0043] The first connecting plate 42 is positioned to avoid hitting the second flip plate 46 during flipping; the second connecting plate 47 is positioned to avoid hitting the first flip plate 41 during flipping; and the first connecting plate 42 and the second connecting plate 47 enhance the stability of the flip assembly.

[0044] Reference Figure 6 and Fig. 9 According to the needs of sorting different pipes, the top ring 451 on the flip cylinder 45 is sleeved on the first push rod 43, and the first flip plate 41 can be flipped. When cutting pipes of another shape, model or size, the translation cylinder 312 is used to push the flip cylinder 45, so that the top ring 451 on the flip cylinder 45 is separated from the first push rod 43, and the top ring 451 is sleeved on the second push rod 48. At this time, the flip cylinder 45 can drive the second flip plate 46 to flip. The flip directions of the first flip plate 41 and the second flip plate 46 are different, and pipes of different shapes, models or sizes can be sorted, reducing manual sorting operations and improving sorting efficiency.

[0045] Reference Fig. 9A lifting cylinder 314 is fixedly arranged at one end of the bracket 31 away from the pipe input, and a baffle 315 is fixedly arranged at the telescopic end of the lifting cylinder 314. The baffle 315 is slidably connected with the bracket 31 in the vertical direction. The lifting cylinder 314 drives the baffle 315 to reciprocate in the vertical direction, so as to adjust the blocking position of the pipe according to the length and diameter of the pipe. When the length of the pipe is greater than the length of the support device 3, the baffle 315 can be lowered, and the pipe extends out of the support device 3. When the pipe is shorter, the baffle 315 is raised when the conveying roller 33 conveys the pipe to prevent the pipe from falling, thereby improving the practicality of the equipment. In order to improve the sliding stability of the baffle 315, a slider is arranged on the side of the baffle 315 away from the conveying roller 33, and a vertical slide groove adapted to the slider is provided on the bracket 31. The slider can be set as a trapezoidal block.
