Description

Technical Field

[0001] The invention relates to the technical field of metal pipe feeding, and in particular to a feeding device for metal pipe processing. Background Art

[0002] Metal pipes are widely used in many fields due to their excellent mechanical properties, corrosion resistance and machinability. In the process of making metal sheets into metal pipes, it is necessary to first select suitable metal sheets according to the needs, and then pre-bend the edges of the metal sheets through a pre-bending machine to form an arc transition to avoid edge cracking during direct curling. The metal sheets are then rolled through a plate rolling machine to gradually curl them into a tube shape. The edges of the curled metal sheets are then welded and sealed using a welding device to form metal pipes. The welds of the metal pipes are then polished and cut into a certain length according to actual needs. The cut metal pipes are transported to the transport trolley through a conveyor rack and stacked into the transport trolley through stacking equipment so that the cut metal pipes can be transferred to the next process for processing.

[0003] The Chinese patent document with announcement number CN221848833U discloses a cutting device for the production of metal pipe fittings that can be automatically stacked, including a cutting frame, one end of the cutting frame is fixedly connected to a limiting structure, the lower end of the interior of the cutting frame is fixedly connected to a cutting machine, one side of the cutting frame is fixedly connected to a stacking frame, the top of the stacking frame is symmetrically fixedly connected to a limiting plate, the lower end of the stacking frame is fixedly connected to a mounting plate, the top of the stacking frame is provided with a through slot, the top of the mounting plate below the through slot is fixedly connected to a driving cylinder, the output end of the driving cylinder is fixedly connected to a support plate, and the top of the stacking frame on one side of the support plate is fixedly connected to a guide frame.

[0004] When in use, first place the long metal pipe on the top of the cutting frame, then adjust the limit piece to the specified position and fix it, and then convey the metal pipe through the feeding structure. Before cutting, press down the limit structure to fix it until the cutting machine cuts the metal pipe. After the first cutting is completed, the metal pipe is conveyed until the cut metal pipe contacts and limits the position, thereby limiting the cutting length of the subsequent metal pipe; when the second cutting is performed, the support plate can be driven downward by the driving cylinder until the top plate pushes the metal pipe on the support plate, so that it falls into the guide frame and is finally collected inside the stacking plate. After two metal pipes are collected inside the stacking plate, the stacking plate is driven down by the lifting cylinder until the next metal pipe can be stacked on the two pipes. At this time, the metal pipe is conveyed by pushing the conveyor, and is bundled by the bundling machine during the period, so as to finally realize the stacking and fixing of the metal pipe.

[0005] However, the above patent document still has the following deficiencies: after the round metal pipe is cut, due to its unique shape, the metal pipe will roll on the guide frame. After the metal pipe stops moving, the stacking device will stack the metal pipe into the transport cart. During this process, once foreign matter appears on the contact surface between the guide frame and the metal pipe or the offset metal pipe falls on the guide frame and rolls, it is easy for the metal pipe rolling along the guide frame to gradually deviate from the original trajectory, so that the distance between the ends of the multiple metal pipes stacked in the transport cart is too far, which is easy to affect the subsequent transfer operation. Summary of the Invention

[0006] The present invention provides a feeding device for metal pipe processing, which aims to solve the problem in the related art that foreign matter or offset metal pipes appearing on the contact surface between the guide frame and the metal pipe fall on the guide frame and roll, which easily causes the metal pipes rolling along the guide frame to gradually deviate from their original trajectory, so that the distance between the ends of multiple metal pipes stacked in the transport cart is too far, which easily affects the subsequent transfer operation.

[0007] The feeding device for metal pipe processing of the present invention includes a conveying mechanism and a guide frame, and also includes an adjustment mechanism. The adjustment mechanism includes a connecting part, a containing part, a mounting part, a second driving source and a blocking part. The connecting part is connected to the guide frame, the mounting part is connected to the connecting part, the containing part is rotatably connected to the mounting part, the containing part is used to contain metal pipes, the blocking part is connected to the rear end of the containing part, the second driving source is rotatably connected to the connecting part, the telescopic end of the second driving source is rotatably connected to the containing part, and the second driving source can drive the containing part to flip so that the metal pipe in the containing part moves backward until the rear end of the metal pipe contacts the blocking part.

[0008] Beneficial effect: When in use, the metal pipe of a set length is cut by an external cutting device, and the cut metal pipe is conveyed by the conveying mechanism. After the metal pipe moves to the set position, the metal pipe is automatically detached under the action of the conveying mechanism, and the metal pipe moves to the guide rack. At this time, the inclined guide rack is used to make the metal pipe roll on the guide rack toward the adjustment mechanism. After the metal pipe rolls into the containing part, the metal pipe is supported by the containing part. At this time, the driving source 2 is started, and the containing part is pushed by the driving source 2 to make the front end of the containing part flip upward. When the containing part flips, the metal pipe inside it can move backward until the rear end of the metal pipe contacts the front side of the blocking part, thereby aligning the metal pipe, so that after the stacking device stacks the metal pipe in the transport trolley, the distance between the ends of multiple metal pipes can be shortened, so as to facilitate the subsequent transportation of multiple metal pipes by the transport trolley.

[0009] Preferably, the containing portion is L-shaped.

[0010] The effect is that the L-shaped containing portion can block the metal pipe by the left side of the inner wall of the containing portion when the metal pipe enters the containing portion.

[0011] Preferably, a mounting opening is provided on the inner bottom side of the containing portion, and a plurality of transmission rollers are rotatably connected in the mounting opening.

[0012] The effect is that when the front end of the containing part flips upward, the metal pipes in the containing part tilt and move backward. At this time, the metal pipes are driven by seven sets of transmission rollers to avoid friction between the metal pipes and the containing part, which may cause damage to the surface of the metal pipes.

[0013] Preferably, the connecting portion is connected to a driving source three, and the telescopic end of the driving source three is connected to the lifting portion.

[0014] The effect is that starting the driving source three can drive the lifting part to move upward, so that the lifting part pushes the metal pipes in the containing part to move upward, and the lifting part can push the metal pipes upward, so that the metal pipes can be stacked into the transport trolley through the stacking equipment later.

[0015] Preferably, a buffer rubber pad is bonded to the left side of the inner wall of the containing portion.

[0016] The effect is that the buffer rubber pad bonded to the left side of the inner wall of the containing portion can prevent the metal pipe from being damaged after a violent collision between the metal pipe and the left side of the inner wall of the containing portion.

[0017] Preferably, a stopping mechanism is further included, which includes a supporting portion, a driving source 1 and a stopping portion, the supporting portion is connected to the guide frame, the driving source 1 is connected to the supporting portion, and the stopping portion is connected to the driving source 1.

[0018] The effect is that: the stop part can be driven to move up and down by a driving source 1, and when the stop part moves up, it can move to the rolling track of the metal pipe on the guide frame. At this time, the metal pipe can be blocked and stopped by the stop part, thereby adjusting the metal pipe to avoid the metal pipe falling off the guide frame due to excessive deviation when the metal pipe rolls on the guide frame, and the number of stop mechanisms can be set according to the length of the guide frame. When the stop part moves down, it can move out of the rolling track of the metal pipe on the guide frame, so that the metal pipe continues to move on the guide frame toward the transport trolley, so as to facilitate the adjustment of the metal pipe through the adjustment mechanism, and at the same time, by stopping the metal pipe by the stop part, the rolling speed of the metal pipe when rolling into the adjustment mechanism can be reduced, so as to avoid damage to the metal pipe after a violent collision between the metal pipe and the adjustment mechanism.

[0019] Preferably, a positioning mechanism is also included, which includes tooth plate one and tooth plate two, tooth plate one is connected to the left side of the containing part, tooth plate two is slidingly connected to the left side of the containing part, tooth plate two is located above tooth plate one, the teeth of tooth plate one face upward, and the teeth of tooth plate two face downward.

[0020] Preferably, the positioning mechanism also includes a fixed sleeve, a counterweight, a sliding part and a gear, the fixed sleeve is connected to the tooth plate 2, the counterweight is inserted into the fixed sleeve, a part of the counterweight extends into the inner side of the containing part, the sliding part is limitedly slidably connected to the left side of the containing part, the gear is rotatably connected to the sliding part, and the tooth plate 1 and the tooth plate 2 are both meshed with the gear.

[0021] Preferably, the rear end face of tooth plate one and the front end face of the blocking part are located on the same plane, the front end face of tooth plate two and the rear end face of the counterweight block are located on the same plane, and the distance between the rear end of tooth plate one and the gear is equal to the distance between the front end of tooth plate two and the gear.

[0022] The effect is that when the front end of the containing part is lifted upward, under the action of the gravity of the counterweight block, the counterweight block can drive the gear plate two to move backward. During the process of the gear plate two moving backward, the driving gear meshes and transmits on the gear plate one, and the gear drives the sliding part to move backward. At this time, because the rear end surface of the gear plate one and the front end surface of the blocking part are located in the same plane, the front end surface of the gear plate two and the rear end surface of the counterweight block are located in the same plane, the distance between the rear end of the gear plate one and the gear is equal to the distance between the front end of the gear plate two and the gear, so that when the gear plate two moves backward and the driving gear meshes and transmits on the gear plate one, the distance between the gear and the front end of the gear plate two and the distance between the gear and the rear end of the gear plate one can always be kept equal. Therefore, after the rear side of the counterweight block contacts the front end of the metal pipe, the gear drives the sliding part to move to the middle position of the metal pipe, thereby positioning the middle position of the metal pipe, so as to push the transport trolley to the middle position of the metal pipe, so as to prevent the metal pipe from leaking out of the transport trolley and affecting the transfer operation of the transport trolley due to the different lengths of the two ends.

[0023] Preferably, the sliding portion is connected to a marking portion, which is a light stick emitting red light.

[0024] The effect is that the red light emitted by the identification part can enable the staff to quickly lock the position of the sliding part.

[0025] The beneficial effects of the present invention are: 1. After a group of metal pipes enters the containing portion, the containing portion blocks the group of metal pipes so that the group of metal pipes is retained in the containing portion. At this time, the second driving source is started, and the front end of the containing portion is driven by the second driving source to flip upward, so that the group of metal pipes in the containing portion moves backward until the rear end of the group of metal pipes contacts the front side of the blocking portion, thereby aligning the group of metal pipes. After the stacking device stacks the group of metal pipes in the transport trolley, the distance between the ends of the multiple metal pipes can be shortened, so that the metal pipes can be subsequently transferred by the transport trolley.

[0026] 2. The driving source drives the stop part to move up and down so that the stop part blocks and stops the metal pipe, thereby adjusting the metal pipe to prevent the metal pipe from falling off the guide frame due to excessive deviation when rolling on the guide frame. The number of stop mechanisms can be set according to the length of the guide frame. At the same time, the stop part stops the metal pipe, which can reduce the rolling speed of the metal pipe when rolling into the adjustment mechanism, so as to avoid damage to the metal pipe after a violent collision between the metal pipe and the adjustment mechanism.

[0027] When the front end of the loading part is lifted upward, the counterweight block can drive the gear plate 2 to move backward under the action of the gravity of the counterweight block, and drive the gear to mesh with the gear plate 1, thereby driving the sliding part to move backward by the gear. At this time, because the rear end surface of the gear plate 1 and the front end surface of the blocking part are located in the same plane, the front end surface of the gear plate 2 and the rear end surface of the counterweight block are located in the same plane, and the distance between the rear end of the gear plate 1 and the gear is equal to the distance between the front end of the gear plate 2 and the gear, so that when the gear plate 2 moves backward and drives the gear to mesh with the gear plate 1, the distance between the gear and the front end of the gear plate 2 and the distance between the gear and the rear end of the gear plate 1 can always be kept equal. After the rear side of the counterweight block contacts the front end of the metal pipe, the gear drives the sliding part to move to the middle position of the metal pipe, thereby positioning the middle position of the metal pipe, so as to push the transport trolley to the middle position of the metal pipe, so as to prevent the metal pipe from leaking out of the transport trolley and affecting the transfer operation of the transport trolley due to the different lengths of the two ends.

[0037] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0038] like Figures 1 to 8As shown, the feeding device for metal pipe processing of the present invention includes a conveying mechanism 1, a guide frame 2, a stopping mechanism 3 and an adjusting mechanism 4. The conveying mechanism 1 can convey the cut metal pipe, the guide frame 2 is connected to the conveying mechanism 1, and the transport trolley is parked on the left side of the guide frame 2. The guide frame 2 can guide the metal pipe that has separated from the conveying mechanism 1 to move toward the transport trolley, so that the metal pipe can be stacked in the transport trolley through the stacking device. The stopping mechanism 3 is connected to the guide frame 2, and the guide frame 2 is inclined. The stopping mechanism 3 can stop the metal pipe rolling on the guide frame 2 and adjust the position of the metal pipe to avoid the metal pipe from rolling on the guide frame 2 due to excessive deviation of the metal pipe. The guide frame 2 falls off, and the adjusting mechanism 4 is connected to the guide frame 2. The end position of the metal pipe can be adjusted by the adjusting mechanism 4, so that after the stacking device stacks the metal pipe in the transport trolley, the distance between the ends of multiple metal pipes can be shortened, so as to facilitate the subsequent transfer of multiple metal pipes by the transport trolley. The positioning mechanism 5 is connected to the adjusting mechanism 4. After the metal pipe is adjusted by the adjusting mechanism 4, the middle position of the metal pipe can be positioned according to the length of the metal pipe, so as to facilitate the transportation trolley to the middle position of the metal pipe, thereby facilitating the stacking device to stack the metal pipe in the middle position of the transport trolley, so as to avoid the metal pipe leaking out of the two ends of the transport trolley and affecting the transportation operation of the transport trolley due to different lengths.

[0039] The metal pipe is first cut by an external cutting device, and then the metal pipe is conveyed by the conveying mechanism 1. After the metal pipe leaves the conveying mechanism 1, the guide frame 2 supports and guides the metal pipe so that the metal pipe rolls on the guide frame 2 toward the transport trolley. When the metal pipe rolls on the guide frame 2, the metal pipe is stopped by the stopping mechanism 3, thereby straightening the metal pipe to prevent the offset metal pipe from continuing to roll on the guide frame 2 and falling from the guide frame 2. Then the stopping mechanism 3 is separated from the metal pipe, and the metal pipe continues to move on the guide frame 2 toward the transport trolley until the metal pipe enters the adjustment mechanism 4, and then the adjustment mechanism 4 is started. The adjustment mechanism 4 adjusts the metal pipe so that the ends of multiple metal pipes are aligned, and the middle position of the adjusted metal pipe is positioned by the positioning mechanism 5. Finally, the stacking device grabs multiple metal pipes and stacks the multiple metal pipes in layers in the transport trolley.

[0040] like Figures 1 to 3As shown, the conveying mechanism 1 includes a frame 11, conveying rollers 12, a driving member 13 and a guide plate 14. The conveying rollers 12 are provided in plurality, and the plurality of conveying rollers 12 are rotatably connected to the frame 11. The driving member 13 is connected to the plurality of conveying rollers 12. The driving member 13 can drive the plurality of conveying rollers 12 to rotate synchronously in the same direction. The plurality of conveying rollers 12 rotating synchronously in the same direction can drive the cut metal pipe to move so as to convey the metal pipe to the guide frame 2. The guide plate 14 is connected to the frame 11. The guide plate 14 is inclined. After the metal pipe conveyed by the plurality of conveying rollers 12 contacts the guide plate 14, the guide plate 14 can guide the metal pipe to separate from the conveying rollers 12. The metal pipe separated from the conveying rollers 12 moves along the guide frame 2 so that the metal pipe can move toward the transport trolley.

[0041] The driving member 13 is started, and the multiple conveying rollers 12 are driven by the driving member 13 to rotate synchronously in the same direction. The multiple conveying rollers 12 that rotate synchronously in the same direction drive the cut metal pipe to move. After the moving metal pipe contacts the guide plate 14, the inclined guide plate 14 can separate the metal pipe from the conveying rollers 12. The metal pipe separated from the conveying rollers 12 falls onto the guide frame 2, and the guide frame 2 supports the metal pipe so that the metal pipe rolls on the guide frame 2 toward the transport trolley.

[0042] like Figure 1 、 Figure 3 and Figure 4 As shown, the stopping mechanism 3 includes a supporting portion 31, a driving source 32 and a stopping portion 33. The supporting portion 31 is connected to the guide frame 2, the driving source 32 is connected to the supporting portion 31, the driving source 32 is a cylinder with the telescopic end facing upward, and the stopping portion 33 is connected to the telescopic end of the driving source 32. The stopping portion 33 can be driven up and down by the driving source 32. When the stopping portion 33 moves upward, it can move to the rolling track of the metal pipe on the guide frame 2. At this time, the metal pipe can be blocked and stopped by the stopping portion 33, thereby adjusting the metal pipe to prevent the metal pipe from rolling on the guide frame 2. When the stop portion 33 moves downward, it can move out of the rolling track of the metal pipe on the guide frame 2, so that the metal pipe can continue to move on the guide frame 2 toward the transport trolley, so that the metal pipe can be adjusted by the adjustment mechanism 4. At the same time, the metal pipe is stopped by the stop portion 33, which can reduce the rolling speed of the metal pipe when it rolls into the adjustment mechanism 4, so as to avoid damage to the metal pipe after a violent collision between the metal pipe and the adjustment mechanism 4.

[0043] Start the driving source 1 32 to drive the stop part 33 to move upward, so that the stop part 33 moves up to the rolling track of the metal pipe on the guide frame 2, and the metal pipe is blocked and stopped by the stop part 33, so as to adjust the metal pipe, and then start the driving source 1 32 again to drive the stop part 33 to move downward, so that the stop part 33 moves out of the rolling track of the metal pipe on the guide frame 2. At this time, the metal pipe is no longer blocked by the stop part 33, and the metal pipe continues to move toward the transport trolley through the inclined guide frame 2 until the metal pipe falls into the adjustment mechanism 4.

[0044] like Figure 1 、 Figures 3 to 5 As shown, the adjustment mechanism 4 includes a connecting portion 41, a containing portion 42, a mounting portion 43, a second driving source 44, a blocking portion 45, a transmission roller 46, a third driving source 47 and a lifting portion 48. The connecting portion 41 is connected to the left side of the guide frame 2, and the containing portion 42 is arranged above the connecting portion 41. The containing portion 42 is L-shaped, and the inner bottom wall of the containing portion 42 and the upper surface of the guide frame 2 are located on the same plane, so that the metal pipe rolling on the guide frame 2 can roll along the upper surface of the guide frame 2 to the inner side of the containing portion 42. A buffer rubber pad (not shown in the figure) is bonded to the left side of the inner wall of the containing portion 42 to avoid the metal pipe from being violently collided with the left side of the inner wall of the containing portion 42. The pipe is damaged, the mounting part 43 is connected to the top rear end of the connecting part 41, the containing part 42 is rotatably connected to the mounting part 43, the driving source 2 44 is rotatably connected to the connecting part 41, the driving source 2 44 is a cylinder with the telescopic end facing upward, the bottom front end of the containing part 42 is rotatably connected to the telescopic end of the driving source 2 44, the blocking part 45 is connected to the rear side of the containing part 42, and the driving source 2 44 is started. The front end of the containing part 42 is driven by the driving source 2 44 to flip upward, and at the same time, the rear end of the containing part 42 rotates on the mounting part 43, so that the metal pipe in the containing part 42 tilts and moves backward until the rear end of the metal pipe contacts the blocking part 45, thereby completing the adjustment of the metal pipe.

[0045] A mounting opening is provided on the inner bottom side of the containing portion 42, and seven groups of transmission rollers 46 are provided. The number of transmission rollers 46 in each group is set to five. The seven groups of transmission rollers 46 are all rotatably connected in the mounting opening, and the multiple groups of transmission rollers 46 are arranged at equal intervals. When the front end of the containing portion 42 is flipped upward, the metal pipe in the containing portion 42 tilts and moves backward. At this time, the metal pipe is transmitted by the seven groups of transmission rollers 46 to avoid friction between the metal pipe and the containing portion 42 and damage to the surface of the metal pipe.

[0046] Driving source three 47 is connected to the connecting part 41. Driving source three 47 is a cylinder with the telescopic end facing upward. The lifting part 48 is connected to the telescopic end of driving source three 47. Starting driving source three 47 can drive the lifting part 48 to move upward, so that the lifting part 48 pushes the metal pipes in the containing part 42 to move upward. At this time, the number of metal pipes in the containing part 42 is ten, and ten metal pipes form a group. The lifting part 48 can push the group of metal pipes upward, so that the group of metal pipes can be stacked into the transport cart through stacking equipment later.

[0047] Every ten metal pipes form a group, and each group of metal pipes can be stopped or discharged by the stopping mechanism 3. After a group of metal pipes rolls into the containing part 42, the driving source 2 44 is started, and the front end of the containing part 42 is driven to flip upward by the driving source 2 44. At the same time, the rear end of the containing part 42 rotates on the mounting part 43, so that the group of metal pipes in the containing part 42 is tilted and moved backward until the rear end of a group of metal pipes contacts the blocking part 45, thereby completing the adjustment of the group of metal pipes. The group of metal pipes is tilted and moved backward, and the metal pipes are transmitted by seven groups of transmission rollers 46. Then, the driving source 3 47 is started to drive the lifting part 48 to move upward, so that the lifting part 48 pushes the group of metal pipes in the containing part 42 to move upward, and finally the stacking equipment stacks the group of metal pipes into the transport cart.

[0048] like Figure 1 、 Figures 3 to 8As shown, the positioning mechanism 5 includes a tooth plate 1 51, a tooth plate 2 52, a fixing sleeve 53, a counterweight 54, a sliding portion 55, a gear 56 and an identification portion 57. The tooth plate 1 51 is connected to the left side of the containing portion 42, the tooth plate 2 52 is limited and slidably connected to the left side of the containing portion 42, the tooth plate 2 52 is located above the tooth plate 1 51, the teeth of the tooth plate 1 51 face upward, and the teeth of the tooth plate 2 52 face downward. The fixing sleeve 53 is connected to the tooth plate 2 52, and the counterweight 54 is inserted into the fixing sleeve 53. A part of the counterweight 54 extends into the inner side of the containing portion 42. When the front end of the containing portion 42 is flipped upward, the counterweight The block 54 can move backward under the action of gravity until the containing part 42 contacts the front end of the metal pipe. A buffer pad made of rubber material can be installed on the side of the counterweight block 54 close to the front end of the metal pipe to avoid damage to the front end of the metal pipe caused by the collision between the counterweight block 54 and the front end of the metal pipe. When the counterweight block 54 moves backward, it can push the tooth plate 2 52 to move backward. The sliding part 55 is limited and slidably connected to the left side of the containing part 42. The gear 56 is rotatably connected to the sliding part 55. The gear 56 is located between the tooth plate 1 51 and the tooth plate 2 52, and the tooth plate 1 51 and the tooth plate 2 52 are both meshed with the gear 56. The gear 56 is connected to the tooth plate 1 51 when the tooth plate 2 moves backward, and the gear 56 drives the sliding part 55 to move backward. The rear end face of the tooth plate 1 51 and the front end face of the blocking part 45 are located on the same plane, and the front end face of the tooth plate 2 52 and the rear end face of the counterweight 54 are located on the same plane. The distance between the rear end of the tooth plate 1 51 and the gear 56 is equal to the distance between the front end of the tooth plate 2 52 and the gear 56. When the tooth plate 2 52 moves backward and drives the gear 56 to mesh with the tooth plate 1 51, the distance between the gear 56 and the front end of the tooth plate 2 52 is equal to the distance between the gear 56 and the front end of the tooth plate 1 51. The distance at the rear end is always kept equal, so that after the rear side of the counterweight block 54 contacts the front end of the metal pipe, the gear 56 can drive the sliding part 55 to move to the middle position of the metal pipe. The identification part 57 is connected to the sliding part 55. The identification part 57 is a light stick that emits red light, so that the staff can quickly lock the position of the sliding part 55 to park the transport trolley in the middle position of the metal pipe, so as to facilitate the stacking device to stack the metal pipe in the middle position of the transport trolley, so as to avoid the metal pipe leaking out of the two ends of the transport trolley due to different lengths and affecting the transfer operation of the transport trolley.

[0049] When the front end of the containing portion 42 is lifted upward, the counterweight 54 drives the tooth plate 2 52 to move backward. During the backward movement of the tooth plate 2 52, the driving gear 56 engages with the tooth plate 1 51 and drives the sliding portion 55 backward. At this time, because the rear end face of the tooth plate 1 51 and the front end face of the blocking portion 45 are located on the same plane, the front end face of the tooth plate 2 52 and the rear end face of the counterweight 54 are located on the same plane, and the distance between the rear end of the tooth plate 1 51 and the gear 56 is the same as the distance between the front end of the tooth plate 2 52 and the gear 56. etc., so that when the gear plate 2 52 moves backward and drives the gear 56 to engage and transmit on the gear plate 1 51, the distance between the gear 56 and the front end of the gear plate 2 52 and the distance between the gear 56 and the rear end of the gear plate 1 51 can always be kept equal. Therefore, after the rear side of the counterweight block 54 contacts the front end of the metal pipe, the gear 56 drives the sliding part 55 to move to the middle position of the metal pipe. At the same time, the identification part 57 on the sliding part 55 emits a red light, so that the staff can quickly lock the position of the sliding part 55 and push the transport cart to the middle position of the metal pipe.

[0050] Working principle: The metal pipe is cut by an external cutting device, and the driving member 13 is started. The driving member 13 drives multiple conveying rollers 12 to rotate synchronously in the same direction. The multiple conveying rollers 12 that rotate synchronously in the same direction drive the cut metal pipe to move. After the moving metal pipe contacts the guide plate 14, the inclined guide plate 14 can separate the metal pipe from the conveying roller 12. The metal pipe separated from the conveying roller 12 falls onto the guide frame 2, and the guide frame 2 supports the metal pipe so that the metal pipe rolls on the guide frame 2 toward the transport trolley.

[0051] Start the driving source 32 to drive the stop part 33 to move upward, so that the stop part 33 moves up to the rolling track of the metal pipe on the guide frame 2, and the ten metal pipes are blocked and stopped at the same time by the stop part 33, and the ten metal pipes are a group, so as to adjust the group of metal pipes, and then start the driving source 32 again to drive the stop part 33 to move downward, so that the stop part 33 moves out of the rolling track of the metal pipe on the guide frame 2. At this time, the group of metal pipes is no longer blocked by the stop part 33, and the group of metal pipes continues to move toward the transport trolley through the tilted guide frame 2 until the group of metal pipes falls into the containing part 42 on the adjustment mechanism 4.

[0052] The second driving source 44 is started, and the front end of the containing portion 42 is driven to flip upward by the second driving source 44. At the same time, the rear end of the containing portion 42 rotates on the mounting portion 43, so that a group of metal pipes in the containing portion 42 tilts and moves backward until the rear ends of the group of metal pipes all contact the blocking portion 45, thereby completing the adjustment of the group of metal pipes. The group of metal pipes tilts and moves backward, and the metal pipes are driven by seven groups of transmission rollers 46.

[0053] When the front end of the containing portion 42 is lifted upward, the counterweight 54 drives the tooth plate 2 52 to move backward. During the backward movement of the tooth plate 2 52, the driving gear 56 engages with the tooth plate 1 51 and drives the sliding portion 55 backward. At this time, because the rear end face of the tooth plate 1 51 and the front end face of the blocking portion 45 are located on the same plane, the front end face of the tooth plate 2 52 and the rear end face of the counterweight 54 are located on the same plane, and the distance between the rear end of the tooth plate 1 51 and the gear 56 is the same as the distance between the front end of the tooth plate 2 52 and the gear 56. etc., so that when the gear plate 2 52 moves backward and drives the gear 56 to engage and transmit on the gear plate 1 51, the distance between the gear 56 and the front end of the gear plate 2 52 and the distance between the gear 56 and the rear end of the gear plate 1 51 can always be kept equal, so that after the rear side of the counterweight block 54 contacts the front end of the metal pipe, the gear 56 drives the sliding part 55 to move to the middle position of the metal pipe, and at the same time, the identification part 57 on the sliding part 55 emits a red light, so that the staff can quickly lock the position of the sliding part 55 and push the transport cart to the middle position of the metal pipe.

[0054] Remove the counterweight 54 and start the driving source 3 47 to drive the lifting part 48 to move upward, so that the lifting part 48 pushes a group of metal pipes in the containing part 42 to move upward, and finally the stacking equipment stacks the group of metal pipes into the transport trolley.

A person skilled in the art may change, modify, replace and modify the above embodiments within the scope of the present invention.
