[0023] In order to make the purpose, technical solutions and advantages of this application more clear, the following further describes this application in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

[0024] The present application provides a butt joint for blanking, the structure of which is as follows: Figure 1 - Figure 3 As shown, it includes a docking mechanism 1 and a fixing component 2.

[0025] The docking mechanism 1 includes an upper head 11 and a lower head 12. The upper head 11 is rotatably connected to the top of the lower head 12. The top of the upper head 11 is used to connect to the bottom of the discharge pipe 14. The bottom of the discharge pipe 14 is provided with a clamp 15. A plurality of sliders 16 are arranged around the bottom of the discharge pipe 14. The clamp 15 is provided with a slide groove 17 for the slider 16 to slide along the height direction of the clamp 15. A return spring 18 is fixedly connected between the slider 16 and the inner wall of the slide groove 17. One end of the return spring 18 is fixedly connected to the slider 16, and the other end of the return spring 18 is fixedly connected to the inner wall of the slide groove 17. The clamp 15 is used to be fixed to the top of the upper head 11. The discharge pipe 14 is a PVC hose. The upper head 11 is used to drive the discharge pipe 14 to rotate, thereby adjusting the aperture of the discharge pipe 14.

[0026] The fixing assembly 2 is provided on the lower head 12 , and the fixing assembly 2 is used to fix the upper head 11 .

[0027] During use, the upper head 11 is rotatably connected to the top of the lower head 12, allowing it to rotate freely relative to the lower head 12. This connection provides the foundation for the upper head 11 to drive the flexible discharge tube 14 to rotate. The upper head 11 is tightly connected to the flexible discharge tube 14. The rotation of the upper head 11 is directly transmitted to the clamp 15, which drives the discharge tube 14 to rotate. As the discharge tube 14 rotates, its shape changes due to its flexible material, thereby adjusting the diameter of the discharge tube 14. When the discharge tube 14 rotates in the forward direction, its length shortens, and the slider 16 slides upward along the chute 17. When the discharge tube 14 rotates in the reverse direction, the discharge tube 14 extends, and the slider 16 slides downward along the chute 17 under the action of the return spring 18. After the diameter of the discharge tube 14 is adjusted, the fixing assembly 2 activates, securing the upper head 11 to the top of the lower head 12, preventing the upper head 11 from rotating accidentally during subsequent discharge operations. The fixing assembly 2 ensures the stability of the aperture of the discharge pipe 14 and ensures the smooth progress of the discharge process.

[0028] In this application, the design of this unloading joint drives the flexible unloading pipe 14 to rotate and adjust the aperture through the upper head 11, thereby achieving precise control of the unloading speed and flow rate, and has the advantages of adapting to different working conditions, facilitating installation and adjustment, and improving production efficiency and safety.

[0029] To achieve self-locking of the upper head 11, please refer to Figure 1 In a preferred embodiment, the upper head 11 is connected to the lower head 12 through a thread 13 .

[0030] During use, the threads 13 not only transmit rotation but also secure the upper head 11. After rotating the upper head 11 to securely engage the lower head 12, the friction and axial pressure between the threads 13 prevent the upper head 11 from accidentally loosening or falling off during operation. To maintain the joint or replace components, the threads 13 can be loosened by rotating the upper head 11 in the opposite direction. This allows for easy separation of the upper head 11 from the lower head 12, facilitating repair or replacement.

[0031] To facilitate the rotation of the upper head 11, please refer to Figure 2 In a preferred embodiment, a handle 3 is provided on the upper head 11 , and a locking assembly 4 for locking the handle 3 is provided on the upper head 11 .

[0032] During use, when adjusting the position of the upper head 11 or rotating the flexible feed tube 14 to adjust the aperture, the operator can grasp and rotate the handle 3. The design of the handle 3 provides the operator with a convenient point of force, making the rotation of the upper head 11 easier and more accurate. The provision of the locking assembly 4 facilitates the installation and removal of the handle 3, making it easy to replace the handle 3.

[0033] In order to make the blanking more stable, please refer to Figure 2 In a preferred embodiment, the handle 3 is provided in plurality, and the plurality of handles 3 are arranged on the upper head 11 along the circumference of the upper head 11 .

[0034] When in use, the provision of multiple handles 3 can make the force during operation more balanced. When the operator applies a rotational force to the upper head 11, the force can be evenly distributed on the multiple handles 3, reducing the tilt or shaking of the upper head 11 caused by uneven force.

[0035] To facilitate the installation and removal of handle 3, please refer to Figure 2 In a preferred embodiment, the locking assembly 4 includes a first bolt 41 threadedly connected to the handle 3, the handle 3 is provided with a first through hole 42 for the first bolt 41 to pass through, and the upper head 11 is provided with a first screw hole 43 for accommodating the first bolt 41.

[0036] During use, to lock the handle 3 to secure the position of the upper head 11, the operator aligns the first bolt 41 with the first through-hole 42 in the handle 3. The first bolt 41 is inserted through the first through-hole 42, with the bolt head positioned on one side of the handle 3 and the bolt thread 13 extending from the other side. The portion of the bolt thread 13 extending from the handle 3 is aligned with the first screw hole 43 in the upper head 11. The first bolt 41 is rotated, gradually threading it into the first screw hole 43. Once the first bolt 41 is fully threaded into the first screw hole 43, the bolt head presses firmly against the handle 3, securing the handle 3 in the specified position on the upper head 11. To unlock the handle 3, the operator uses a tool to rotate the first bolt 41 in the opposite direction. As the bolt rotates in the opposite direction, it gradually unscrews from the first screw hole 43. The pressure between the bolt head and the handle 3 gradually decreases. Once the first bolt 41 is fully threaded out of the first screw hole 43, it separates from the upper head 11, and the handle 3 becomes free to move.

[0037] In order to make the end surface of the handle 3 smoother, please refer to Figure 2 In a preferred embodiment, the handle 3 is provided with a first countersunk groove 44 for accommodating the first bolt 41 .

[0038] During use, if the bolt head protrudes from the surface of handle 3, it could collide with the operator or other objects during operation, causing injury or damage to the equipment. The first countersunk groove conceals the bolt head, reducing the risk of collision and improving operational safety. A protruding bolt head is susceptible to external impact or friction, potentially causing the bolt to loosen. Hiding the bolt head in the first countersunk groove reduces the impact of external forces on the bolt and the possibility of accidental loosening, thereby ensuring the stability and reliability of locking assembly 4.

[0039] To improve security, please refer to Figure 2 In a preferred embodiment, an arc chamfer 31 is provided on the end of the handle 3 away from the upper head 11.

[0040] During use, the operator's hand may come into contact with the end of the handle 3. If the end of the handle 3 is a sharp right angle, it is easy to scratch the operator's hand. However, the design of the arc chamfer 31 can make the end of the handle 3 more rounded, greatly reducing the risk of scratching and improving the safety of operation.

[0041] To fix the upper head 11, please refer to Figure 3 In a preferred embodiment, the fixing assembly 2 includes a second bolt 21 connected to the lower head 12 by a thread 13, and the lower head 12 is provided with a second threaded hole 13 for accommodating the second bolt 21, and the end of the second bolt 21 is used to abut against the side wall of the upper head 11.

[0042] During use, when the upper head 11 needs to be fixed, the operator aligns the second bolt 21 with the second threaded hole 13 of the lower head 12. The second bolt 21 is rotated so that the bolt is gradually screwed into the second threaded hole 13. As the second bolt 21 continues to be screwed in, its end eventually abuts against the side wall of the upper head 11. The abutment of the end of the second bolt 21 against the side wall of the upper head 11 achieves a secure connection between the upper head 11 and the lower head 12. In the fixed state, the upper head 11 will not rotate accidentally due to external forces or vibrations during the unloading process, ensuring the stability of the connection between the unloading tube 14 and the equipment.

[0043] To improve the stability of the fixation, please refer to Figure 3 In a preferred embodiment, the pitch of the threads 13 at the bottom of the upper head 11 is equal to the diameter of the second bolt 21 .

[0044] During use, when the second bolt 21 is screwed into the second threaded hole 13 of the lower head 12 and abuts the side wall of the upper head 11 to achieve fixation, since the spacing between the threads 13 at the bottom of the upper head 11 is equal to the diameter of the second bolt 21, the second bolt 21 can fit neatly into the gap between the threads 13 at the bottom of the upper head 11. In this way, the second bolt 21 and the threads 13 at the bottom of the upper head 11 form a tight fit, increasing the stability of the fixation. The bolt not only fixes the upper head 11 by generating friction through the end abutting the side wall of the upper head 11, but also further prevents the upper head 11 from rotating by fitting with the gap between the threads 13. This design makes the fixing assembly 2 more secure and reliable when fixing the upper head 11. When the upper head 11 is subjected to external forces or vibrations during the blanking process, the tight fit between the second bolt 21 and the threads 13 at the bottom of the upper head 11 can better resist these external forces, reducing the possibility of the upper head 11 loosening or displacement.

[0045] To reduce the possibility of the second bolt 21 loosening, please refer to Figure 3 In a preferred embodiment, an anti-loosening gear 23 is provided on the second bolt 21, and a slot 24 is provided on the lower head 12. An anti-loosening tooth block 25 engaged with the anti-loosening gear 23 is clamped in the slot 24.

[0046] During use, when it is necessary to fix the upper head 11, the operator rotates the second bolt 21 so that its end gradually abuts the side wall of the upper head 11. As the second bolt 21 is tightened, the bolt gradually penetrates into the second threaded hole 13 of the lower head 12. During the tightening process of the second bolt 21, the anti-loosening gear 23 on the bolt gradually approaches the slot 24 of the lower head 12. When the second bolt 21 is tightened to a certain extent, the anti-loosening gear 23 engages with the anti-loosening tooth block 25 in the slot 24. The engagement of the anti-loosening gear 23 and the anti-loosening tooth block 25 further enhances the stability of the fixing assembly 2. This meshing relationship can prevent the second bolt 21 from loosening or reversing when subjected to external force.

[0047] In order to better understand this application, the following Figure 1 - Figure 3 The working principle of the technical solution of the docking joint for blanking of the present application is described in detail: the upper head 11 is rotatably connected to the top of the lower head 12, so that the upper head 11 can rotate freely relative to the lower head 12. This connection method provides a basis for the upper head 11 to drive the flexible blanking tube 14 to rotate. The upper head 11 is tightly connected to the flexible blanking tube 14. The rotation of the upper head 11 can be directly transmitted to the blanking tube 14, causing the blanking tube 14 to rotate accordingly. When the blanking tube 14 rotates, due to the characteristics of its flexible material, the shape of the blanking tube 14 will change, thereby adjusting the aperture of the blanking tube 14. After the aperture of the blanking tube 14 is adjusted, the fixing component 2 comes into play to fix the upper head 11 on the top of the lower head 12 to prevent the upper head 11 from accidentally rotating during the subsequent blanking process. The fixing component 2 ensures the stability of the aperture of the blanking tube 14 and ensures the smooth progress of the blanking process.
