The pushing mechanism is adapted to push a stainless steel pipe on the feeding rack so that the stainless steel pipe is transferred to the conveyor line via the transfer mechanism. This feeding device of the stainless steel pipe processing machine can automatically transfer the stainless steel pipe to the conveyor line without the need for human operation, thus saving manpower and improving work efficiency.

[0004] In the production workshop, most steel pipes are piled on the ground. When processing the steel pipes, workers need to manually move the steel pipes to the loading device, and the steel pipes need to be lifted to a high place before they can be placed on the loading device. The process is dangerous, and manual handling of the steel pipes is laborious, which will affect the loading speed of the steel pipes. Therefore, it is urgent to design an intermittent loading device for steel pipe processing to solve the above problems. Summary of the Invention

[0031] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0032] like Figure 1-11As shown, an intermittent feeding device for steel pipe processing provided by an embodiment of the present invention includes a support assembly 1, a box body 3 is provided on the top outer wall of the support assembly 1, and a feeding assembly 2 is installed on the outer wall of one side of the box body 3 by bolts, the feeding assembly 2 includes a feeding hopper 18, two electric rollers 19 are installed inside the feed hopper 18 through bearings, and a crawler 20 is wound between the two electric rollers 19, a plurality of metal hooks 21 are installed on the side outer wall of the crawler 20 by bolts, a mounting shell 4 is installed on the outer wall of one side of the box body 3 by bolts, and a discharge barrel 6 is installed on the outer wall of one side of the mounting shell 4 by bolts.

[0033] Specifically, in this embodiment, it includes a support assembly 1, a box body 3 is provided on the top outer wall of the support assembly 1, and a feed assembly 2 is installed on the outer wall of one side of the box body 3 by bolts. The feed assembly 2 includes a feed hopper 18, and two electric rollers 19 are installed inside the feed hopper 18 through bearings. The model of the electric roller 19 is preferably a Chengdu Shuangxiong Tengda external electric roller, and a crawler 20 is wound between the two electric rollers 19. A plurality of metal hooks 21 are installed on the side outer wall of the crawler 20 by bolts. When the support assembly 1 is pushed to move on the ground, The feed hopper 18 can be moved toward the steel pipe, and during this process, the two electric rollers 19 can be operated to start, so that the crawler track 20 rotates and the metal hook 21 rotates. Later, when the steel pipe enters the feed hopper 18, the steel pipe will be hooked by the rotating metal hook 21, and then move with the metal hook 21, and then fall into the box body 3, thereby realizing automatic picking up of the steel pipe and reducing the labor workload of the workers. The outer wall of one side of the box body 3 is installed with a mounting shell 4 by bolts, and the outer wall of one side of the mounting shell 4 is installed with a discharge barrel 6 by bolts.

[0034] The present invention provides an intermittent feeding device for steel pipe processing. When the support assembly 1 is pushed to move on the ground, the feed hopper 18 can be moved toward the steel pipe. During this process, the two electric rollers 19 can be operated to start, so that the crawler 20 rotates and the metal hook 21 rotates. Subsequently, when the steel pipe enters the feed hopper 18, the steel pipe will be hooked by the rotating metal hook 21, and then move with the metal hook 21, and then fall into the box body 3, thereby realizing automatic picking up of the steel pipe, reducing the labor of workers, and helping to improve the efficiency of subsequent steel pipe processing.

[0035] The inspection mechanism includes a bent frame 201 installed on the side wall of the crawler 20, and the bent frames 201 are provided in plurality and arranged in an array on the side wall of the crawler 20; a conical frame 202 is installed at the bottom end of each bent frame 201, and the bottom shape of the bent frame 201 is a groove shape, and this shape is adapted to the shape of the steel pipe, and a limiting unit is installed on the upper side of the side wall of the bent frame 201, and the limiting unit is used to limit the steel pipe to be inspected, and a pressure sensor 203 is installed at the end of the conical frame 202; during operation, when the cone frame 202 on the outside of the crawler 20 touches the steel pipe on the ground during rotation, refer to the attached figure. Figure 8 and Figure 9 As shown, the conical part of the conical frame 202 will first contact the bottom of the steel pipe, and at the same time, the pressure sensor 203 at the end of the conical frame 202 will be subjected to force, and the electrical signal is transmitted through the pressure sensor 203 to connect the external circuit. Then the external controller will control the limit unit to support one side of the steel pipe, so that the bending frame 201 can continue to follow the rotation of the crawler 20 and smoothly feed the steel pipe into the groove at the bottom of the bending frame 201, thereby realizing automatic picking and inspection of the steel pipe, and facilitating the subsequent loading of the steel pipe.

[0036] The limiting unit includes an electric push rod 204 installed on the side wall of the bending frame 201, and the telescopic end of the electric push rod 204 is fixedly installed with a limiting frame 205. A rectangular support plate 206 is slidably installed inside the limiting frame 205, and an arc plate 1 207 is fixedly installed on the upper end surface of the rectangular support plate 206. The side wall of the bending frame 201 is installed with an arc plate 208 through an electric telescopic rod 209. During operation, when the conical frame 202 contacts the steel pipe on the ground, the rotation speed of the crawler 1 20 is first reduced, and then the external controller drives the telescopic end of the electric push rod 204 to move, and the electric push rod 204 will drive the limiting frame 205 and the rectangular support plate 206 to the adjacent The side of the near circular arc plate 208 moves, and then the circular arc plate 1 207 on the surface of the rectangular supporting plate 206 will contact the circular arc plate 208, and under the extrusion of the circular arc plate 208, the circular arc plate 1 207 drives the rectangular supporting plate 206 to move downward. When the highest point of the arc of the circular arc plate 1 207 contacts the highest point of the arc of the circular arc plate 208, the rectangular supporting plate 206 moves to the maximum distance and presses on the side wall of the steel pipe. Such a design can avoid the problem of the steel pipe moving away from the conical frame 202 due to the action of inertia when the conical frame 202 contacts the steel pipe, and facilitates the steel pipe to enter the groove of the bending frame 201 along the surface of the conical frame 202, thereby facilitating the loading of the steel pipe.

[0037] When the rectangular support plate 206 moves, the rectangular support plate 206 will drive the sliding rod 210 to slide in the limit groove, so that the rectangular support plate 206 can be pressed against the surface of the steel pipe; when the steel pipe is placed inside the groove of the bending frame 201, the track 1 20 has rotated normally, and the steel pipe will squeeze the pressure sensor 2 212 in the groove of the bending frame 201. At this time, the external controller will control the electric telescopic rod 209 to drive the arc plate 208 away from the rectangular support plate 206. The rectangular support plate 206 recovers under the action of the telescopic spring 211, and then continues to control the electric push rod 204 to pull the rectangular support plate 206 away from the steel pipe, making it convenient for the steel pipe to be transported along the track 1 20 and fall into the subsequent box 3.

[0038] In one embodiment provided by the present invention, Figure 2-4 As shown, the support assembly 1 includes four legs 7, each of which has a cavity 12 formed inside, and a sliding plate 16 is slidably connected inside the cavity 12. A universal wheel 17 is installed on the outer wall of one side of the bottom of the sliding plate 16 by bolts, and a connecting spring 15 is installed on the outer wall of one side of the top of the sliding plate 16 by bolts, and the top of the connecting spring 15 is installed on the top of the inner wall of the cavity 12 by bolts. A connecting rod 2 9 is installed between two adjacent legs 7 by bolts, and a connecting rod 1 8 is installed in groups of two by bolts. A cavity 13 is formed inside the connecting rod 1 8 and the connecting rod 2 9, and the cavity 13 and the cavity 12 are interconnected. An oil tank 10 is installed on the outer wall of one side of the bottom of one of the connecting rods 8 by bolts, and the oil tank 10 and the cavity 13 are interconnected. A threaded rod 11 is installed inside the oil tank 10 through a bearing, and the outer thread of the threaded rod 11 is threadedly connected to the piston plate 14. When using this device When the oil pump is turned on, the piston plate 14 is retracted to the oil tank 10, so that the oil pump is turned on and the oil tank 10 is turned off. When the oil pump is turned on, the piston plate 14 is retracted to the oil tank 10, so that the oil pump is turned on and the oil tank 10 is turned off. When the oil pump is turned on, the piston plate 14 is retracted to the oil tank 10, so that the oil pump is turned on and the oil tank 10 is turned off.

[0039] In another embodiment provided by the present invention, Figure 6As shown, a slope portion 22 is integrally formed on the bottom of the inner wall of the box body 3, and an electric roller 23 is installed inside the box body 3 and the mounting shell 4 through bearings. The model of the electric roller 23 is preferably the Chengdu Shuangxiong Tengda external electric roller, and a track 24 is wound between the two electric rollers 23. A plurality of metal hooks 25 are installed on the outside of the track 24 through bolts. When the two electric rollers 23 are started, the track 24 moves, and the metal hook 25 moves with the steel pipe that slides down due to the slope portion 22, so that the steel pipe moves to the inside of the mounting shell 4.

[0040] In another embodiment provided by the present invention, a rotating cylinder 26 is installed inside the mounting shell 4 through a bearing, and a plurality of grooves 27 are provided on the side outer wall of the rotating cylinder 26. The grooves 27 facilitate the rotating cylinder 26 to catch the steel pipe that falls from the metal hook 25. A driving motor 5 is installed on the outer wall of one side of the mounting shell 4 through bolts. The model of the driving motor 5 is preferably 85BYGH450A-040-35. As the driving motor 5 is started, the rotating cylinder 26 will rotate with the steel pipe, causing the steel pipe to fall to the bottom of the mounting shell 4, and then the steel pipe will flow out through the discharge cylinder 6 and then fall onto the processing equipment, thereby realizing automatic loading of the steel pipe, and the output end of the driving motor 5 is fixedly connected to the rotating cylinder 26 through a flat key.

[0041] Working principle: When using the device, you can first rotate the threaded rod 11 to make the piston plate 14 move inside the oil tank 10, so that the piston plate 14 squeezes the medium oil inside the oil tank 10, so that the medium oil flows into the cavity 13, and then flows into the cavity 12 through the structure inside the connecting rod 1 8 and the connecting rod 2 9, thereby squeezing the sliding plate 16 inside the cavity 12, so that the universal wheel 17 moves inside the cavity 12, so that the universal wheel 17 contacts the ground. Subsequently, as the universal wheel 17 extends, the universal wheel 17 will lift the support leg 7 to facilitate workers to carry the device, so that the device is close to the ground. When the steel pipe is placed on the ground and the support assembly 1 is pushed to move on the ground, the feed hopper 18 can be moved towards the steel pipe, and in this process, the two electric rollers 19 can be operated to start, so that the crawler 20 rotates and the metal hook 21 rotates. Later, when the steel pipe enters the feed hopper 18, the steel pipe will be hooked by the rotating metal hook 21, and then move with the metal hook 21, and then fall into the box body 3, realizing the automatic picking of the steel pipe and reducing the labor of the workers. When the cone frame 202 on the outside of the crawler 20 touches the steel pipe on the ground during the rotation, refer to the attached figure. Figure 8 and Figure 9As shown, the conical portion of the conical frame 202 will first contact the bottom of the steel pipe, and at the same time, the pressure sensor 203 at the end of the conical frame 202 will be subjected to force, and the electrical signal transmitted by the pressure sensor 203 will connect the external circuit. Then, the external controller will control the limit unit to support one side of the steel pipe, so that the bending frame 201 can continue to follow the rotation of the crawler 20 and smoothly feed the steel pipe into the groove at the bottom of the bending frame 201, thereby realizing automatic picking and inspection of the steel pipe, thereby facilitating the subsequent loading of the steel pipe.

[0042] When the conical frame 202 contacts the steel pipe on the ground, the rotation speed of the crawler 20 is first reduced, and then the external controller drives the telescopic end of the electric push rod 204 to move, and the electric push rod 204 will drive the limit frame 205 and the rectangular support plate 206 to move to the side close to the arc plate 2 208. After that, the arc plate 1 207 on the surface of the rectangular support plate 206 will contact the arc plate 2 208, and under the squeezing of the arc plate 208, the arc plate 1 207 drives the rectangular support plate 206 to move downward. When the highest point of the arc of the arc plate 1 207 contacts the highest point of the arc of the arc plate 2 208, the rectangular support plate 206 moves to the maximum distance and presses on the side wall of the steel pipe. This design can prevent the conical frame 202 from contacting the steel pipe. When in contact, the steel pipe is away from the conical frame 202 due to the effect of inertia, which facilitates the steel pipe to enter the groove of the curved frame 201 along the surface of the conical frame 202, thereby facilitating the loading of the steel pipe; when the steel pipe is placed inside the groove of the curved frame 201, the crawler 1 20 has rotated normally, and the steel pipe will squeeze the pressure sensor 2 212 in the groove of the curved frame 201. At this time, the external controller will control the electric telescopic rod 209 to drive the arc plate 208 away from the rectangular support plate 206. The rectangular support plate 206 recovers under the action of the telescopic spring 211, and then continues to control the electric push rod 204 to pull the rectangular support plate 206 away from the steel pipe, facilitating the transportation of the steel pipe along the crawler 1 20 and falling into the subsequent box 3;

[0043] The above steps are subsequently repeated to allow the device to automatically pick up the steel pipe. After the picking is completed, the device can be moved to a suitable position, and then the threaded rod 11 is rotated in the opposite direction to retract the piston plate 14 to one end of the oil tank 10, so that the medium oil is not under force, and then under the action of the connecting spring 15 and gravity, the sliding plate 16 will retract the universal wheel 17 into the cavity 12, so that the device is placed stably on the ground, and then the two electric rollers 23 are operated to start, so that the crawler 24 moves, and the metal hook 25 moves with the steel pipe that slides down due to the slope 22, so that the steel pipe moves to the inside of the mounting shell 4, and then the steel pipe will fall into the groove 27. Then, as the drive motor 5 is started, the rotating cylinder 26 will rotate with the steel pipe, so that the steel pipe falls into the bottom of the mounting shell 4, and then the steel pipe will flow out through the discharge cylinder 6 and then fall into the processing equipment, realizing automatic loading of the steel pipe.

[0044] The above description is merely illustrative of certain exemplary embodiments of the present invention. It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims.
