Description

Technical Field

[0001] This utility model relates to the field of pipe packaging technology, specifically to a conveying mechanism for an automatic pipe packaging machine. Background Technology

[0002] Pipes are a fundamental material widely used in modern industry, and their packaging plays a crucial role in the production process. The prerequisite for packaging is the efficient and stable transport of pipes to designated locations, requiring the conveying system to operate quickly, accurately, and reliably. In automatic pipe packaging machines, the conveying mechanism is a core component. Its function is not only to transport the pipes but also to rationally distribute them to subsequent processing equipment to ensure the continuity and efficiency of the packaging operation. Therefore, an efficient conveying mechanism is of great significance for improving the overall performance of the pipe packaging machine.

[0003] Application number CN201320689834.9 discloses a feeding device for an automatic pipe packaging machine, comprising a frame, a pipe conveying channel, a first push rod, and a second push rod. The distance between the first and second push rods is an integer multiple of the diameter of a single pipe. The lifting and lowering of the first and second push rods are controlled by the control device of the automatic packaging machine. A guide claw assembly is provided at the entrance of the pipe conveying channel. The height of the pipe conveying channel is greater than the diameter of the pipe to be packaged but less than twice the diameter of the pipe to be packaged. This application automatically and quantitatively picks up pipes according to the working progress of the automatic packaging machine and conveys them to the worktable in a single row, significantly improving work efficiency and providing a prerequisite guarantee for the automatic packaging of pipes.

[0004] However, existing technologies still suffer from the problem that conveying mechanisms generally rely on individual components to independently complete material distribution or conveying actions, lacking effective linkage between the various structures. This intermittent working mode results in a discontinuous conveying process, with the mechanical actions of each component acting independently, severely reducing the overall efficiency of pipe conveying. Utility Model Content

[0005] In view of the shortcomings of the prior art, the purpose of this utility model is to provide a conveying mechanism for an automatic pipe packaging machine, which realizes the coordinated operation of material distribution and conveying through a linkage structure, thereby improving the continuity of the conveying process and the overall efficiency.

[0006] The present invention adopts the following technical solution: The conveying mechanism includes: a frame on which a material conveying mechanism, a material distribution mechanism and a material discharge mechanism are provided; the material conveying mechanism includes an inlet end, a material transfer area and a material drop end, wherein the material transfer area is used to transport the pipe from the inlet end to the material drop end along the horizontal axis; the material distribution mechanism is located below the material transfer area and includes: a plurality of equidistant material guiding devices, a plurality of pressing devices spaced apart between adjacent material guiding devices, a material support device correspondingly located below the pressing device, and a material slowing device placed on the material transfer path of the material guiding device and the material support device; the material discharge mechanism includes a material discharge port that is linked and connected with the material support device; wherein, after the pipe falls from the material drop end, it is limited by the material guiding device and the material slowing device, and then moves sequentially to the material support device. The pressing device presses and fixes a portion of the pipe on the material support device and drives the material support device to press down synchronously. When the material support device is pressed down to connect with the material discharge port, the pipe that is close to the material discharge port and has not been pressed and fixed is discharged and transported through the material discharge port.

[0007] As a preferred technical solution of this utility model, several of the material guiding devices are arranged at equal intervals perpendicular to the material transmission path of the material transmission area below the material dropping end. The spacing between them is greater than the minimum length of the pipe, so as to receive and guide the pipe to the material support device when it falls.

[0008] As a preferred technical solution of this utility model, each of the guiding devices includes: an inclined plate, which is fixed to the frame by a support frame, and the inclined direction gradually moves downward away from the conveying area to form a high loading end to receive the pipe falling from the unloading end, and a low unloading end for the pipe to detach; a support frame, a connecting piece that is fixed to the inclined plate and the frame, which together with the inclined plate form a triangular cross-section support frame; and a stop block, which is placed in front of the unloading end to block and guide the pipe to move onto the material receiving device.

[0009] In a preferred embodiment of this utility model, the material support device is positioned below the pressing device and includes: a base frame with an L-shaped cross-section, a groove on its short side and a strip-shaped groove on its long side; a limiting block with a discharge port on the base frame and a slot on it; a lifting plate with an end face for receiving the pipe, which is adapted to the shape of the groove on the base frame, one end of which is slidably connected to the base frame through the groove, and the other end abutting against the slot of the limiting block; and a return spring elastically connected between the bottom surface of the lifting plate and the groove of the base frame. The pressing device presses down on the pipe on the end face of the lifting plate, simultaneously driving the lifting plate down into the groove to connect the discharge port to the pipe. The return spring is used to reset the lifting plate after the pressing device rises.

[0010] As a preferred technical solution of this utility model, the pressing device is fixed on the frame by a mounting base and threadedly connected to the mounting base for adjusting the downward pressing position in the horizontal direction; the pressing device achieves vertical telescopic pressing by a cylinder.

[0011] As a preferred technical solution of this utility model, the pressing block surface of the pressing device is provided with a plurality of telescopic tubes arranged in an array. The plurality of telescopic tubes form a flat contact surface in the horizontal direction. After the pressing block abuts against the pipe, the contact surface is recessed around the abutment contour of the pipe to form a recessed part. The recessed part limits and clamps the pipe to adapt to the pressing of pipes with different diameters.

[0012] As a preferred technical solution of this utility model, a baffle is provided at the feeding end, and the baffle extends along the pipe transportation direction; an inclined guide plate is provided at the dropping end. When the pipe moving along the horizontal axis in the material transfer area contacts the guide plate at one end, it is gradually guided by the guide plate and falls laterally onto the material guiding device in a direction perpendicular to the axis.

[0013] As a preferred technical solution of this utility model, the slowing device includes: a grooved wheel, which is disposed on the material transmission path between the unloading end and the material support device, and is rotatably connected to the frame, with the rotation direction being away from the unloading end; the surface of the grooved wheel is provided with an arc-shaped groove adapted to the diameter of the pipe, which is used to slow down the movement of the pipe falling from the unloading end, and to smoothly arrange the pipe onto the material support device by rotation.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. The transportation mechanism of this application consists of a material conveying mechanism and a material support device and a pressing device in the material distribution mechanism. The various parts are connected and cooperate to realize the transportation, distribution and discharge of pipes. The linkage between the pressing device and the material support device means that the pressing action of the lifting plate drives the lifting plate of the material support device to move down synchronously, so that the pipe connects with the discharge port and slides out naturally. After resetting, the operation is repeated to realize the coordination of material distribution and conveying actions, and improve the continuity of the conveying process and the overall efficiency.

[0016] 2. The pressing device in this application uses an array of telescopic tubes arranged on its surface to automatically adjust the contact surface according to the shape and diameter of the pipe, forming a recess around the pipe to achieve precise fitting of pipes of different diameters. Simultaneously, the telescopic tubes actively conform to the outer contour of the pipe upon contact, achieving efficient positioning through adaptive adjustment. This effectively reduces stress concentration during the pressing process and minimizes the risk of pipe deformation or indentation defects.

[0027] To enable those skilled in the art to better understand the technical solutions in this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0028] Please refer to the conveying mechanism of this utility model for an automatic tube packaging machine. Figures 1 to 7 As shown, the conveying mechanism achieves efficient conveying and coordinated discharge of the pipe 5 through the material conveying mechanism 2, the material distribution mechanism 3, and the discharge mechanism set on the frame 1. The material conveying mechanism 2 includes a feeding end 21, a material transfer area 22, and a dropping end 23. The material transfer area 22 is used to convey the pipe 5 from the feeding end 21 along the horizontal axis to the dropping end 23. To stabilize the conveying process, the feeding end 21 is provided with a baffle 211, which extends along the conveying direction of the pipe 5 and is used to guide and limit the pipe 5 entering the material transfer area 22. The dropping end 23 is provided with an inclined guide plate 231. When the pipe 5 is conveyed horizontally along the material transfer area 22, the end of the pipe 5 close to the guide plate 231 contacts the guide plate 231 and is gradually guided by the inclined surface of the guide plate 231 to leave the material transfer area 22, so that the pipe 5 falls laterally into the guiding device 31 in the material distribution mechanism 3 in a manner perpendicular to the horizontal axis.

[0029] The material distribution mechanism 3 is located below the material transfer area 22. It consists of several equally spaced guiding devices 31, spaced pressing devices 32, and corresponding material support devices 33 located below the pressing devices 32. The guiding devices 31 are used to receive the pipes 5 guided down from the dropping end 23 and move them onto the material support devices 33. The pressing devices 32 press down and fix some of the pipes 5 on the material support devices 33, while driving the material support devices 33 to move down synchronously. When the material support devices 33 descend along the guide trajectory to a predetermined position connected to the discharge port 4 under the action of the pressing devices 32, the pipes 5 on the material support devices 33 that are close to the discharge port 4 and not fixed by the pressing devices 32 are released and directionally conveyed through the discharge port 4. The pipes 5 that have been pressed and fixed, as well as the pipes 5 located on the side of the fixed pipes 5 away from the discharge port 4, are also restricted and remain in place. That is, through the cooperation of the above-mentioned mechanisms, the orderly transportation and coordinated discharge of pipe 5 can be achieved, ensuring the accuracy of batch discharge and the stability of the process.

[0030] Furthermore, in the material distribution mechanism 3 located below the dropping end 23, several guiding devices 31 are arranged at equal intervals perpendicular to the material transfer path of the material transfer area 22, and the arrangement spacing between the guiding devices 31 is greater than the minimum length of the pipe 5. Specifically, when the pipe 5 falls from the dropping end 23 of the material transfer area 22, the guiding devices 31 restrict and guide the gravity and direction of movement of the falling pipe 5 through the inclined plates 311 and the arrangement spacing, so as to avoid excessive collision or stacking of the pipe 5 due to free fall. At the same time, the spacing arrangement of the guiding devices 31 ensures that pipes 5 of different lengths can be received and guided to the supporting device 33 by at least two guiding devices 31 in their length direction, thereby improving the adaptability of the pipe 5.

[0031] Furthermore, each guiding device 31 includes an inclined plate 311, a support frame 312, and a stop 313, which cooperate to receive, guide, and transport the pipes 5 falling from the discharge end 23. Specifically, the inclined plate 311 is fixed to the frame 1 via the support frame 312 and gradually tilts downwards in a direction away from the conveying area, forming a high loading end and a low unloading end. The inclined plate 311 uses gravity to allow the pipes 5 to slide naturally to the unloading end after falling, thereby avoiding vibration and displacement caused by the direct fall of the pipes 5. The support frame 312, as the connecting part between the inclined plate 311 and the frame 1, is set as a support frame with a triangular cross-section, enhancing the stability of the guiding device 31, while ensuring that the inclined plate 311 can maintain a stable guiding function when carrying multiple pipes 5. The stop 313 set in front of the unloading end is used to block and position the pipes 5 sliding to the lower position, constraining their movement path and guiding the pipes 5 smoothly to the support device 33.

[0032] In a preferred embodiment, a buffer device 34 is provided in the material transfer path between the unloading end and the material support device 33, specifically below the stop block 313 and near the unloading end. This buffer device 34 is a grooved wheel rotatably connected to the frame 1, rotating away from the unloading end. The surface of the grooved wheel has an arc-shaped groove adapted to the diameter of the pipe 5, used to slow the movement speed of the pipe 5 as it falls from the unloading end, reducing the impact force of directly falling into the material support device 33 and preventing the pipes 5 from directly stacking or misaligning. Through the rotation of the grooved wheel, the pipes 5 falling from the unloading end roll into the arc-shaped groove of the grooved wheel and rotate synchronously with it until they naturally fall onto the material support device 33. Thus, the pipes can be smoothly and orderly arranged and transported onto the material support device 33, achieving buffering and stable transmission of the pipes 5.

[0033] Furthermore, the material support device 33 is positioned below the pressing device 32 and consists of a base frame 331, a limiting block 332, a lifting plate 333, and a return spring 334. It receives the pipe 5 conveyed by the material distribution mechanism 3 and is linked to the discharge of the pipe 5 via lifting control. Specifically, the base frame 331 has an L-shaped cross-section, with a groove on its short side to limit the sliding stroke of the lifting plate 333, and a strip-shaped groove on its long side to accommodate the lifting plate 333. The limiting block 332 and the base frame 331 share a common side that forms the discharge port 4 connecting to the discharge mechanism. The slot of the limiting block 332 engages with one end of the lifting plate 333, ensuring that the lifting plate 333 remains stable in its initial position. The end face of the lifting plate 333 is used to receive the pipe 5 conveyed by the upper guiding device 31, and its end face gradually tilts towards the discharge port 4, so that the pipe 5 moves naturally due to gravity. One end of the limiting block 332 is slidably connected to the base frame 331 through a sliding groove to ensure smooth lifting, and the other end abuts against the slot of the limiting block 332 to lock the position. At the same time, a return spring 334 is installed on the bottom surface of the lifting plate 333. One end of the spring is connected to the bottom surface of the lifting plate 333, and the other end is connected to the strip groove of the base frame 331. When the pressing device 32 presses down, the lifting plate 333 moves down synchronously, pressing and fixing the pipe 5 and lowering it into the groove of the base frame 331, completing the connection with the discharge port 4, releasing the pipe 5 near the discharge port 4, and achieving precise discharge. After the pressing device 32 rises, the elasticity of the return spring 334 causes the lifting plate 333 to return to the initial position, preparing for the next reception and conveying of pipe 5.

[0034] Furthermore, the pressing block 322 of the pressing device 32 has several telescopic tubes 323 arranged in an array on its surface. These telescopic tubes 323 are arranged horizontally to form a flat contact surface. When the pressing block 322 contacts the pipe 5 to be fixed, the contact surface deforms according to the outer contour of the pipe 5, forming a recess around the contact area. This recess, by wrapping and clamping the pipe 5, achieves the adaptation, limiting, and fixing of pipes 5 of different diameters, effectively avoiding slippage, tipping, or loosening of the pipe 5 due to diameter mismatch during the pressing process. In addition, the telescopic tubes 323 allow the pressing block 322 to flexibly adjust when contacting pipes 5 of different diameters, avoiding the limitations of traditional rigid pressing blocks 322 on the workpiece's adaptability, thus significantly improving the system's adaptability to multiple specifications of pipes 5.

[0035] Working principle: First, the pipe 5 enters the conveying mechanism 2 through the feed end 21 and is conveyed horizontally along the conveying area 22. When the pipe 5 reaches the discharge end 23, the inclined guide plate 231 of the discharge end 23 causes one end of the pipe 5 to contact the guide plate 231, and then it gradually changes from horizontal movement to vertical direction and falls into the distribution mechanism 3. The distribution mechanism 3 receives the pipe 5 falling from the discharge end 23 through the inclined plate 311, and, together with the stop block 313 and the slowing device 34, arranges the pipe 5 in a staggered manner. The tubes 5 fall orderly onto the supporting device 33 below. The lifting plate 333 of the supporting device 33 initially maintains an inclined end face by being engaged with the return spring 334 and the limiting block 332. When the pressing device 32 presses a portion of the tube 5 on the lifting plate 333, the lifting plate 333 moves downwards until it connects with the discharge port 4. The pressed and fixed tube 5 naturally falls into the discharge port 4 due to the gravity of its inclined end face, while the pressed and fixed tube 5 remains on the supporting device 33. The pressing block 322 of the pressing device 32, through an array of telescopic tubes 323 arranged on its surface, automatically adapts to form a recess around the tube 5 after contact, achieving reliable clamping and limiting of tubes 5 of different diameters. When the pressing device 32 resets, the return spring 334 returns the lifting plate 333 to its initial position, completing one round of operation and preparing for the next round of conveying.
