Description

Technical Field

[0001] This invention relates to the field of steel pipe feeding technology, specifically to a fully automatic steel pipe feeder with adjustable pipe length. Background Technology

[0002] The production process of steel pipes also includes the reprocessing of steel pipes, including rust removal, polishing, coating and sealing. Before the reprocessing process, batches of steel pipes need to be sorted and stacked to facilitate the feeding process of the process.

[0003] It should be noted that the steel pipes undergoing reprocessing are of varying lengths. Therefore, during the batch stacking and sorting of the steel pipes, to ensure neat arrangement, the lengths within the sorting structure must remain relatively constant. Consequently, when sorting batches of steel pipes of varying lengths, two situations arise: first, excessively long steel pipes cannot be placed into the sorting structure; second, excessively short steel pipes leak out of the sorting structure, causing disorder in the overall steel pipe sorting process and hindering subsequent processes.

[0004] In view of the above-mentioned technical problems, this application proposes a solution. Summary of the Invention

[0005] The purpose of this invention is to provide an adjustable-length fully automatic steel pipe feeder. For the process of sorting and feeding steel pipes of different lengths, the different lengths of the steel pipes affect the overall sorting process and subsequently affect the subsequent processing steps.

[0006] The objective of this invention can be achieved through the following technical solution: a fully automatic steel pipe feeder with adjustable pipe length, comprising a housing and a base platform. The housing is mounted on the base platform, and two side pressure plates are slidably installed inside the housing. The two side pressure plates are arranged in a mirror-symmetrical manner along the centerline of the housing length. A feeding structure is provided on one outer wall of the housing, and two second electric push rods are installed on the other outer wall of the housing. The positions of the two second electric push rods correspond to the positions of the side pressure plates, and the second electric push rods... The output shaft is connected to the side pressure plate. An inward feeding strip is installed on the outer wall of the two side pressure plates that are close to each other. A servo cylinder is installed inside the base platform. An assembly mounting plate is installed at the output end of the servo cylinder. The assembly mounting plate is slidably connected to the base platform in the vertical direction. Two support plate frames are installed on the assembly mounting plate. Multiple insertion holes are opened at the bottom of the box near the unloading structure. The support plate frames pass through the insertion holes. The box has corresponding sliding grooves for the side pressure plates.

[0007] The inward feeding bar is further configured as follows: the inward feeding bar consists of an upper support bar and a lower support bar, with one end of the upper support bar and the lower support bar connected together. The upper support bar is located at the end away from the feeding structure and is inclined in the direction of the feeding structure. The lower support bar is located at the end close to the feeding structure and is inclined downward in the horizontal direction.

[0008] The material feeding structure is further configured as follows: the material feeding structure includes a chute frame, an external slide plate frame, and an angle adjustment plate. The angle adjustment plate is mounted on the side pressure plate. One end of the chute frame is mounted on the angle adjustment plate, and the other end of the chute frame is mounted on the external slide plate frame. The chute frame is slidably connected to the external slide plate frame along the length of the box.

[0009] The external skateboard frame is further configured such that it is parallel to the length of the box and is positioned below the upper surface of the box.

[0010] The configuration is further defined as follows: an outward pressure plate is provided on one side of one of the side pressure plates, the outward pressure plate is slidably connected to the upper surface of the housing, and the upper surface of the outward pressure plate is higher than the upper surface of the side pressure plate; a first electric push rod is installed on one side of the housing, and the end of the transmission rod of the first electric push rod is connected to the outward pressure plate.

[0011] Further configuration: the upper surface of the outward pressure plate is horizontal, the side pressure plate is provided with a material sorting groove, the side of the material sorting groove near the material feeding structure is inclined upward in the horizontal direction, and the other side of the material sorting groove matches the upper support bar in the inward feeding bar.

[0012] A further configuration is provided: the top of the support plate frame has an outward notch, and the opening direction of the outward notch points towards the material feeding structure.

[0013] The present invention has the following beneficial effects:

[0014] 1. This invention addresses the steel pipe stacking process during steel pipe processing. Specifically, it uses two side pressure plates to flatten and neatly press the steel pipes. Then, it utilizes two reciprocating support plates. The process is as follows: the support plates push one of the steel pipes upwards until it moves to the corresponding position on the slide rail, and slides down along the slide rail, thus realizing automatic stacking and feeding.

[0015] 2. Based on the above technology, an outward pressure plate at a single position is first added. The purpose is to allow multiple steel pipes of different lengths to be placed on two side pressure plates. The freely movable outward pressure plate ensures that one end of each steel pipe is flush with the other. With the corresponding movement of the two side pressure plates, steel pipes of the corresponding length can be sorted out in ascending order. The movement distance and direction of the side pressure plates are then used to sort, stack, and feed the steel pipes of the corresponding lengths. Furthermore, the support plate frame is optimized by adding an outward notch to prevent the steel pipes from detaching from the support plate frame during the upward movement.

[0024] The technical solution of the present invention will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0025] Example 1

[0026] In the feeding process of steel pipe processing, due to different production methods, the lengths of steel pipes vary. Therefore, in the processing of batches of steel pipes of varying lengths, it is necessary to first stack and sort the batch of steel pipes. Subsequently, the following problems may occur: steel pipes that are too long cannot be placed into the steel pipe sorting structure, or steel pipes that are too short will leak out of the steel pipe sorting structure. To address this, the following technical solution is proposed:

[0027] Reference Figures 1-4 The fully automatic steel pipe feeder with adjustable pipe length in this embodiment includes a housing 1 and a base platform 2. The housing 1 is mounted on the base platform 2, and two side pressure plates 5 are slidably installed inside the housing 1. The two side pressure plates 5 are arranged in a mirror-symmetrical manner along the centerline of the length of the housing 1. A feeding structure is provided on one outer wall of the housing 1, and two second electric push rods 16 are installed on the other outer wall of the housing 1. The positions of the two second electric push rods 16 correspond to the positions of the side pressure plates 5, and the output shafts of the second electric push rods 16 are connected to the side pressure plates 5. An inward feeding strip 8 is installed on the outer wall of the side where the two side pressure plates 5 are close to each other. A servo cylinder 17 is installed inside the base platform 2, and an assembly mounting plate 12 is installed at the output end of the servo cylinder 17. The assembly mounting plate 12 is slidably connected to the base platform 2 in the vertical direction, and two support plate frames 13 are installed on the assembly mounting plate 12. The housing 1 is close to the bottom Multiple insertion ports 9 are provided at the bottom of the internal structure of the material feeding structure. The support plate frame 13 passes through the insertion ports 9. The box body 1 is provided with a sliding groove 4 corresponding to the side pressure plate 5. The inward feeding bar 8 is composed of an upper support bar and a lower support bar. One end of the upper support bar and the lower support bar are connected. The upper support bar is located at the end away from the feeding structure and is inclined in the direction of the feeding structure. The lower support bar is located at the end close to the feeding structure and is inclined downward in the horizontal direction. The feeding structure includes a sliding groove frame 7, an external sliding plate frame 10 and an angle adjustment plate 6. The angle adjustment plate 6 is installed on the side pressure plate 5. One end of the sliding groove frame 7 is installed on the angle adjustment plate 6 and the other end of the sliding groove frame 7 is set on the external sliding plate frame 10. The sliding groove frame 7 is slidably connected to the external sliding plate frame 10 along the length direction of the box body 1. The external sliding plate frame 10 is parallel to the length direction of the box body 1 and the setting position of the external sliding plate frame 10 is lower than the upper surface of the box body 1.

[0028] Working principle: This invention only includes the feeding process and does not elaborate on the steel pipe processing equipment. First, let's look at the attached... Figure 1 Appendix Figure 2 Appendix Figure 3 In the initial state, the two side pressure plates 5 approach each other under the action of the second electric push rod 16, and the distance between the two side pressure plates 5 becomes smaller. Then, when a batch of steel pipes of different lengths are placed on the two side pressure plates 5, the steel pipes whose length is equal to the distance between the two side pressure plates 5 fall back to the lower side of the two side pressure plates 5. It should be noted here that the initial distance between the side pressure plates 5 needs to be less than the minimum length of the batch of steel pipes.

[0029] Afterwards, when the steel pipe falls into the interior of the two side pressure plates 5, it will not fall directly into the bottom of the box 1, but will fall directly into the inward feeding bar 8. Under the action of the steel pipe's gravity, the steel pipe slides along the lower support bar of the inward feeding bar 8 towards the position close to the feeding structure, so that steel pipes of the same length are gradually piled up in the inward feeding bar 8.

[0030] Finally, according to the feeding position set in the steel pipe processing, the tilt angle of the slide frame 7 is adjusted, but the upper position of the slide frame 7 is always flush with the upper surface of the box 1. Then, under the action of the start servo cylinder 17, the assembly mounting plate 12 is driven to move back and forth in the vertical direction. When the assembly mounting plate 12 drives the two support plate frames 13 to move upward, the two support plate frames 13 drive the steel pipe at the bottom of the inward feeding bar 8 to move upward until the steel pipe moves to the position of the corresponding slide frame 7. The steel pipe enters the slide frame 7. Under the action of gravity, the steel pipe slides down along the tilt direction of the slide frame 7. After the support plate frame 13 is reset, another batch of steel pipes is fed one by one.

[0031] It should be noted that the moving direction and moving distance of the side pressure plate 5 are determined according to the length of the steel pipe. For example, after a shorter steel pipe is fed into the processing equipment, the distance between the two side pressure plates 5 can be expanded to accommodate a slightly longer steel pipe. The control method can rely on the electrical control method detected by the sensor, which will not be described here.

[0032] Example 2

[0033] This embodiment proposes the following optimization scheme based on the working principle of Embodiment 1:

[0034] Reference Figure 1 , Figure 5 and Figure 6An outward pressure plate 11 is provided on one side of one of the side pressure plates 5. The outward pressure plate 11 is slidably connected to the upper surface of the box body 1, and the upper surface of the outward pressure plate 11 is higher than the upper surface of the side pressure plate 5. A first electric push rod 3 is installed on one side of the box body 1. The end of the transmission rod of the first electric push rod 3 is connected to the outward pressure plate 11. The upper surface of the outward pressure plate 11 is horizontal. A material sorting trough 15 is provided on the side pressure plate 5. The side of the material sorting trough 15 near the unloading structure is inclined upward in the horizontal direction, and the other side of the material sorting trough 15 matches the upper support bar in the inward feeding bar 8. An outward notch 14 is provided at the top of the support plate frame 13. The opening direction of the outward notch 14 points to the unloading structure.

[0035] Working principle: Based on the technical solution of Embodiment 1, when a batch of steel pipes is placed on the side pressure plate 5, they will first slide into the stacking and sorting trough 15. During this process, it should be noted that the two ends of the batch of steel pipes are not flat. For this reason, an outward pressure plate 11 is added at a single position. The outward pressure plate 11 is in contact with one of the side pressure plates 5. The purpose is to use the outward pressure plate 11 to flatten one end of the batch of steel pipes. When sorting steel pipes of different lengths, as shown in Embodiment 1, after a portion of shorter steel pipes are stacked and fed, the other side pressure plate 5 moves away from the outward pressure plate 11 to widen the distance between the two side pressure plates 5. The slightly longer steel pipes continue to fall into the inward feeding bar 8, while the longer steel pipes cannot fall into the inward feeding bar 8. This satisfies the stacking process of steel pipes of other lengths until all steel pipes are stacked.

[0036] As for the support plate 13 in Embodiment 1, its main function is to support the steel pipe. Therefore, in order to prevent the steel pipe from accidentally falling off during the process of supporting the steel pipe, an outward notch 14 is added. Under the premise of preventing the steel pipe from falling off, it can also ensure that the steel pipe is discharged only in the direction of the downward material structure.

[0037] In summary: Regarding the steel pipe stacking process in steel pipe processing, firstly, two side pressure plates are used to level and stack various types of steel pipes. Then, a reciprocating support plate frame is used to push the steel pipes at fixed positions into the chute frame, realizing the feeding action of all steel pipes. On this basis, an inward feeding bar is first added to the side pressure plates to stack steel pipes of the same length. Then, an outward pressure plate is added at a single position to make the ends of pipes of different lengths level. Furthermore, by utilizing the opposing movement of the side pressure plates and the single movement of the outward pressure plate, pipes of different lengths are sorted and stacked in order from shortest to longest.
