A large wood panel transfer mechanism using suction cups

Abstract

This utility model discloses a suction cup mechanism for transferring large timber boards, including a central cylinder with telescopic horizontal lifting cylinders fixedly connected to both sides. An extension tube is inserted into the other end of each telescopic horizontal lifting cylinder. This suction cup mechanism for transferring large timber boards utilizes an internal thread to activate the rotating cylinder, generating a threaded displacement force on the surface of the extension tube. This, combined with an internal rectangular positioning rod, constrains the rotation direction of the extension tube, causing it to extend and retract outward within the telescopic horizontal lifting cylinder. This allows for adjustment of the distance between the two large suction cups according to different sizes of timber boards. A vacuum pump extracts the gas adsorbed inside the timber boards by the large suction cups, using the pressure difference to firmly adhere the timber boards to the suction cups. This allows for adjustable suction and lifting based on different sizes of timber boards, enabling stable lifting by directly adsorbing the large suction cups onto the stable points of the timber boards.

Description

Technical Field

[0001] This utility model relates to the technical field of suction cup mechanisms for transferring wood panels, specifically a large suction cup mechanism for transferring wood panels. Background Technology

[0002] During the processing and loading of timber boards, due to their large size and heavy weight, they all require lifting and transfer using hoisting equipment. Currently, in existing timber processing plants, the transfer of large timber boards primarily involves wrapping and securing lifting slings around the surface of the boards and using a lifting frame. This operation requires manual binding of each board of different sizes beforehand to establish lifting points, and manual assistance is needed to ensure the lifting slings are taut before lifting. This process is extremely cumbersome and not very safe. Therefore, to address these problems, this application proposes a suction cup mechanism for transferring large timber boards. This mechanism can be adjusted in length according to different sizes of timber boards, allowing for stable suction and lifting of different sizes of timber boards using pressure differential, thus enabling rapid and stable transfer of large timber boards. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a suction cup mechanism for large-scale wood board transfer, which solves the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a suction cup mechanism for transferring large wood panels, comprising a central cylinder, telescopic horizontal hanging cylinders fixedly connected to both sides of the central cylinder, an extension tube inserted into the other end of the telescopic horizontal hanging cylinder, a connecting cylinder fixedly sleeved at the other end of the extension tube, the bottom end of the connecting cylinder being fixedly connected to the top surface of a large suction cup, a vacuum pump fixedly installed on the outer surface of the connecting cylinder, the output pipe of the vacuum pump being inserted into the interior of the large suction cup, and the bottom surfaces of both large suction cups adsorbing onto the surface of the wood panel.

[0005] Preferably, a rectangular positioning inner rod is slidably sleeved on the inner wall of the extended tube, and the end of the rectangular positioning inner rod is fixedly connected to the inner wall of the telescopic horizontal lifting cylinder. A threaded groove is opened on the surface of the extended tube, and a toothed cylinder is rotatably connected to the end of the telescopic horizontal lifting cylinder. An internally threaded starting cylinder is fixedly installed on the other side of the toothed cylinder. The inner wall of the internally threaded starting cylinder is threadedly sleeved on the surface of the extended tube. The inner ring of the toothed cylinder is movably sleeved on the surface of the extended tube, and a push-locking toothed cylinder is sleeved on the outer ring of the toothed cylinder.

[0006] Preferably, the inner wall of the push-moving toothed cylinder is engaged with the surface of the toothed cylinder, the inner wall of the push-moving toothed cylinder is slidably engaged with the surface of the telescopic horizontal hanging cylinder, two positioning sliders are fixedly provided on the inner wall of the push-moving toothed cylinder, and the front and back of the telescopic horizontal hanging cylinder are provided with grooves for use with the positioning sliders.

[0007] Preferably, one end of the positioning slider is inserted into a groove on the surface of the telescopic horizontal lifting cylinder and is slidably connected to the inner wall of the groove. The surface of the telescopic horizontal lifting cylinder is provided with a threaded groove, and a push adjustment sleeve is threadedly fitted onto the surface of the telescopic horizontal lifting cylinder. The edge of the push adjustment sleeve is rotatably connected to the edge of the push toothed cylinder.

[0010] This utility model provides a suction cup mechanism for transferring large wooden boards. It has the following beneficial effects:

[0011] (1) The large timber board is transferred using a suction cup mechanism. By adjusting the threaded displacement of the top-push adjusting sleeve on the surface of the telescopic horizontal lifting cylinder, it drives the push-moving toothed cylinder to slide on the surface of the telescopic horizontal lifting cylinder, thus separating the meshing sleeve of the push-moving toothed cylinder and the toothed cylinder. This allows the inner thread starting cylinder to rotate and adjust accordingly. Then, the threaded displacement force generated by the rotation of the inner thread starting cylinder on the surface of the outer tube, combined with the internal rectangular positioning rod, constrains the rotation direction of the outer tube, thereby causing the outer tube to extend and retract outward inside the telescopic horizontal lifting cylinder. This allows the distance between the two large suction cups to be adjusted according to different sizes of timber boards, making the lifting force more stable. The vacuum pump extracts the gas adsorbed inside the timber board by the large suction cups, and the pressure difference allows the large suction cups to firmly adsorb the timber board, so that it can be adjusted and adsorbed for different sizes of timber boards at any time. This avoids the tedious manual operation of wrapping and binding the surface of the timber board one by one in the early stage, and allows it to be directly adsorbed by the large suction cups at a stable point of force, making it easy to lift and transport it stably.

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figure 1-8As shown, this utility model provides a technical solution: a suction cup mechanism for transferring large wooden boards, including a central cylinder 1, with telescopic horizontal lifting cylinders 2 fixedly connected to both sides of the central cylinder 1. An extension tube 3 is inserted into the other end of the telescopic horizontal lifting cylinder 2, and a connecting cylinder 4 is fixedly sleeved onto the other end of the extension tube 3. The bottom end of the connecting cylinder 4 is fixedly connected to the top surface of a large suction cup 5. A vacuum pump 8 is fixedly installed on the outer surface of the connecting cylinder 4, and the output pipe of the vacuum pump 8 is inserted into the interior of the large suction cup 5. The bottom surfaces of both large suction cups 5 are adsorbed onto the surface of the wooden board 20. Through the vacuum pump 8, the gas adsorbed inside the wooden board 20 by the large suction cups 5 is extracted, and the pressure difference causes the large suction cups 5 to firmly adsorb and press the wooden board 20, thus lifting the wooden board. 20 is more secure. A contact edge plate 6 is fixedly fitted around the outer edge of the large suction cup 5. A sealing contact gasket ring is fixedly installed on the bottom surface of the contact edge plate 6. Three reinforcing diagonal braces 7 are fixedly installed on the top surface of the contact edge plate 6. The other ends of the three reinforcing diagonal braces 7 are fixedly connected to the surface of the connecting cylinder 4. Through the setting of the contact edge plate 6 and the reinforcing diagonal braces 7, the large suction cup 5 is more securely attached to the wooden board 20, distributing the force between the connecting cylinder 4 and the large suction cup 5 during lifting, thus protecting the large suction cup 5. A rectangular positioning inner rod 16 is slidably fitted onto the inner wall of the extension tube 3. The end of the rectangular positioning inner rod 16 is fixedly connected to the inner wall of the telescopic horizontal lifting cylinder 2. Through the setting of the rectangular positioning inner rod 16, the rectangular positioning inner rod 16 slides and displaces inside the extension tube 3, from... To prevent the extended tube 3 from rotating during its extension and retraction within the telescopic horizontal lifting cylinder 2, the surface of the extended tube 3 is provided with a threaded groove. A toothed cylinder 9 is rotatably connected to the end of the telescopic horizontal lifting cylinder 2. An internally threaded starting cylinder 10 is fixedly installed on the other side of the toothed cylinder 9. The inner wall of the internally threaded starting cylinder 10 is threadedly fitted onto the surface of the extended tube 3. Through the setting of the internally threaded starting cylinder 10, the threaded displacement force generated by the rotation of the internally threaded starting cylinder 10 on the surface of the extended tube 3 is achieved. This, combined with the internal rectangular positioning rod 16, constrains the rotation direction of the extended tube 3, thereby allowing the extended tube 3 to extend and retract outward within the telescopic horizontal lifting cylinder 2. This achieves the ability to adjust the two large suction cups 5 according to different sizes of wooden boards 20. The spacing between them allows for stable lifting. The inner ring of the toothed cylinder 9 is movably sleeved with the surface of the outer extension tube 3. The outer ring of the toothed cylinder 9 is fitted with a push-lock toothed cylinder 12. The inner wall of the push-lock toothed cylinder 12 meshes with the surface of the toothed cylinder 9 and slides with the surface of the telescopic horizontal lifting cylinder 2. Two positioning sliders 14 are fixedly installed on the inner wall of the push-lock toothed cylinder 12. The front and back of the telescopic horizontal lifting cylinder 2 are provided with grooves 13 that cooperate with the positioning sliders 14. One end of the positioning slider 14 is inserted into the groove 13 on the surface of the telescopic horizontal lifting cylinder 2 and is slidably connected with the inner wall of the groove 13. Through the setting of the groove 13 and the positioning slider 14, the push-lock toothed cylinder 12 cannot rotate when it slides on the surface of the telescopic horizontal lifting cylinder 2.This ensures that when the push-locking toothed cylinder 12 and the toothed cylinder 9 are engaged, the rotational direction of the toothed cylinder 9 is fixed. The surface of the telescopic horizontal lifting cylinder 2 has a threaded groove, and a push-adjusting sleeve 15 is threadedly fitted onto the surface of the telescopic horizontal lifting cylinder 2. The edge of the push-adjusting sleeve 15 is rotatably connected to the edge of the push-locking toothed cylinder 12. By adjusting the setting of the push-adjusting sleeve 15, the threaded displacement of the push-adjusting sleeve 15 on the surface of the telescopic horizontal lifting cylinder 2 is adjusted, thereby causing the push-locking toothed cylinder 12 to slide on the surface of the telescopic horizontal lifting cylinder 2, thus controlling the sliding displacement of the push-locking toothed cylinder. Whether the meshing sleeve of 12 and the gear cylinder 9 is disengaged allows control over whether the internal thread starting drum 10 can rotate and be adjusted. Multiple rotating handles 11 are fixedly installed on the outer surface of the internal thread starting drum 10. A lifting clamp 17 is fixedly installed on the top of the central cylinder 1. A docking insert 18 is fixedly fitted onto the surface of the lifting clamp 17. Locking protrusions 19 are fixedly installed around the docking insert 18. The docking insert 18 and locking protrusions 19 enhance the stability of the lifting clamp 17 when connected to the boom of an external lifting device.

[0023] In use, first adjust the distance between the two large suction cups 5 according to the size and model of the timber board to be lifted, i.e., the position of the adhesion point with the timber board (if the two adhesion points are too large or too small, it will seriously affect the stability of lifting the timber board). Rotate the adjusting push sleeve 15 to make it threadedly displace on the surface of the telescopic horizontal lifting cylinder 2, thereby driving the push-moving toothed cylinder 12 to slide on the surface of the telescopic horizontal lifting cylinder 2, separating the meshing engagement between the push-moving toothed cylinder 12 and the toothed cylinder 9. At this time, the rotation positioning of the toothed cylinder 9 on the internal thread starting cylinder 10 fails. Then, the internal thread starting cylinder 10 can be rotated for adjustment, using the threaded displacement generated by the rotation of the internal thread starting cylinder 10 on the surface of the extension tube 3 as... Apply force, and in conjunction with its internal rectangular positioning rod 16, constrain the rotation direction of its extension tube 3, causing the extension tube 3 to extend and retract outward within the telescopic horizontal lifting cylinder 2. This allows the distance between the two large suction cups 5 to be adjusted according to different sizes of wood boards 20. Then, press the two large suction cups 5 onto the appropriate suction points of the wood board 20. Next, use the vacuum pump 8 to extract the gas adsorbed inside the wood board 20 by the large suction cups 5, and use the pressure difference to make the large suction cups 5 firmly adsorb and press the wood board 20. Subsequently, the lifted wood board 20 can be transported to the required location. Meanwhile, all contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0024] In summary, this large timber board rotating mechanism utilizes a suction cup mechanism. By adjusting the threaded displacement of the push-adjusting sleeve 15 on the surface of the telescopic horizontal lifting cylinder 2, it causes the push-moving toothed cylinder 12 to slide on the surface of the telescopic horizontal lifting cylinder 2, thus separating the meshing engagement of the push-moving toothed cylinder 12 and the toothed cylinder 9. This allows the internal thread starting cylinder 10 to rotate and adjust accordingly. Then, the threaded displacement force generated by the rotation of the internal thread starting cylinder 10 on the surface of the outer extension tube 3, combined with the internal rectangular positioning rod 16, constrains the rotation direction of the outer extension tube 3, thereby allowing the outer extension tube 3 to extend... The outward extension and retraction of the internal structure of the horizontal lifting cylinder 2 allows for adjustment of the distance between the two large suction cups 5 according to different sizes of wood boards 20, making the lifting force more stable. The vacuum pump 8 extracts the gas adsorbed inside the wood board 20 by the large suction cups 5, and the pressure difference makes the large suction cups 5 firmly adsorb the wood board 20. This allows for adjustment and lifting of the wood board 20 according to different sizes of wood boards 20, avoiding the tedious manual wrapping and binding of the wood board surface in the early stage. It allows the large suction cups 5 to directly adsorb the wood board for lifting, making it easier to transport.
