Description

Technical Field

[0001] This utility model relates to a material lifting device for a waste removal machine, belonging to the field of waste removal machine technology. Background Technology

[0002] Semiconductors are materials whose conductivity at room temperature is between that of conductors and insulators. Semiconductors have wide applications in radios, televisions, and temperature measurement. For example, diodes are devices made using semiconductors. Semiconductors are materials whose conductivity can be controlled, ranging from that of insulators to conductors. From both a technological and economic development perspective, the importance of semiconductors is enormous. Today, most electronic products, such as computers, mobile phones, or digital recorders, have core components that are closely related to semiconductors. Common semiconductor materials include silicon, germanium, and arsenide. The body material of semiconductors is often obtained by stamping and decomposing the frame material in a waste removal machine. During the stamping and decomposition of the frame, the waste edges on the frame are removed, also known as deburring.

[0003] Chinese utility model patent CN221936923U discloses an automatic material lifting device for a waste removal machine, including a base box with an air inlet pipe connected to an air supply device. The base box also has a material lifting assembly. The lifting assembly includes a fixed pipe and a lifting pipe. The fixed pipe is vertically inserted from the top of the base box and fixedly connected to it. The lifting pipe is coaxially arranged with the fixed pipe, its bottom end fitted over the top of the fixed pipe, and its top end sealed. The lifting pipe and fixed pipe are slidably and sealingly connected. The lifting pipe is elastically connected to the base box via an elastic element. This utility model uses the lifting pipe to lift the frame after the reinforcement is cut, creating a gap between the frame and the lower mold for easy handling. Furthermore, by venting air through the air vents onto the upper surface of the upper mold, impurities generated on the lower mold surface during reinforcement cutting are blown away, preventing damage during subsequent frame reinforcement cutting. However, in the existing technology, when the frame is lifted, it will continue to rise and fall due to inertia, which affects the stability of lifting the material. The falling position is difficult to determine, which can easily cause the frame to slip to the ground, requiring workers to pick it up manually. This operation is cumbersome and reduces work efficiency.

[0004] Therefore, a material lifting device is needed for the waste removal machine to improve the stability of material lifting. Utility Model Content

[0025] The components include: mold 1, cutting cavity 2, lifting tube 3, fixed column 4, through hole 5, sealing plate 6, driving cavity 7, adsorption hole 8, cylinder 9, air hole 10, sealing ring 11, lifting rod 12, support block 13, electromagnet 14, magnet block 15, and spring 16. Detailed Implementation

[0026] like Figures 1-6As shown, a material lifting device for a waste removal machine in this embodiment includes a mold 1, a cutting cavity 2 is provided on the top of the mold 1, and a material lifting mechanism is provided on the mold 1.

[0027] The lifting mechanism includes a lifting tube 3, a fixed column 4, a through hole 5, and a sealing plate 6. The bottom of the mold 1 is provided with a driving cavity 7, and the through hole 5 is located at the top of the driving cavity 7. The driving cavity 7 is connected to the cutting cavity 2 through the through hole 5. The lifting tube 3 passes vertically through the through hole 5. A first lifting component is provided in the driving cavity 7. The first lifting component is used to drive the lifting tube 3 to rise and fall. The sealing plate 6 is located inside the lifting tube 3. The sealing plate 6 is sealed and fixedly connected to the inner wall of the lifting tube 3. The sealing plate 6 and the lifting tube 3 are integrally formed. The sealing plate 6 is provided with an adsorption hole 8. The top of the lifting tube 3, the top of the sealing plate 6, and the bottom of the cutting cavity 2 are all on the same plane. The fixed column 4 is coaxially arranged with the lifting tube 3. The bottom end of the lifting tube 3 is sleeved with the fixed column 4. The lifting tube 3 and the fixed column 4 are slidably and sealedly connected.

[0028] During use, the bottom end of the fixed column 4 is fixedly installed on the waste removal machine. After the frame is placed in the rebar cutting chamber 2 and the rebar is cut, the lifting pipe 3 is raised by the first lifting component. In fact, at this time, the frame blocks the adsorption hole 8. When the lifting pipe 3 rises, the air pressure in the lifting pipe 3 decreases. Under the action of air pressure, the adsorption hole 8 adsorbs the frame. When the lifting pipe 3 has finished rising, the frame is lifted and the staff can remove the frame. Finally, the lifting pipe 3 is lowered by the first lifting component to reset it.

[0029] The first lifting component is a cylinder 9. The piston end of the cylinder 9 is fixedly connected to the lifting pipe 3. There are two cylinders 9, which are located on both sides of the lifting pipe 3. During operation, the cylinder body of the cylinder 9 is fixedly connected to the waste removal machine.

[0030] The lifting tube 3 is provided with an air hole 10, and a sealing ring 11 is coaxially provided inside the lifting tube 3. The sealing ring 11 is sealed and slidably connected to the inner wall of the lifting tube 3. The air hole 10 and the sealing ring 11 are both located between the sealing plate 6 and the fixed column 4. A second lifting assembly is provided inside the lifting tube 3. The second lifting assembly is used to drive the sealing ring 11 to rise and fall.

[0031] In the initial state, the sealing ring 11 blocks the air hole 10, and there is a gap between the sealing ring 11 and the sealing plate 6. During the rise of the lifting pipe 3, the air pressure in the lifting pipe 3 decreases. When the lifting pipe 3 rises to the highest point, the air hole 10 is located above the cutting chamber 2. The sealing ring 11 is raised by the second lifting component, so that air can enter the lifting pipe 3 from the air hole 10, causing the adsorption hole 8 to stop adsorbing the frame, making it easy for the staff to remove the frame from the sealing plate 6.

[0032] After the frame is removed, the lifting tube 3 descends. In fact, at this time, the sealing ring 11 blocks the adsorption hole 8. That is, the air in the lifting tube 3 is squeezed and discharged from the air hole 10 and acts on the cutting chamber 2. The impurities generated during the cutting process are blown away by the airflow, so as to avoid the impurities causing damage to the frame during subsequent cutting.

[0033] It should be noted that when the air hole 10 is completely inside the through hole 5, the sealing ring 11 is lowered by the second lifting component to achieve reset, so that the air in the lifting pipe 3 can be discharged from the adsorption hole 8.

[0034] Multiple air holes 10 and multiple through holes 5 are provided, and the multiple through holes 5 and multiple air holes 10 are evenly distributed circumferentially with the axis of the lifting pipe 3 as the center.

[0035] The sealing ring 11 is made of rubber, which is soft and reduces the impact force generated when the sealing ring 11 comes into contact with the sealing disc 6.

[0036] The distance between the air hole 10 and the axis of the lifting pipe 3 is twice the inner diameter of the sealing ring 11, and the height of the sealing ring 11 is greater than the diameter of the air hole 10.

[0037] The second lifting assembly includes a lifting rod 12, a support block 13, and an electromagnet 14. The lifting rod 12 is vertically arranged between a sealing ring 11 and a fixed column 4. The top end of the lifting rod 12 is fixedly arranged on the sealing ring 11, and a magnet 15 is fixedly arranged at the bottom end of the lifting rod 12. The support block 13 is fixedly arranged on the inner wall of the lifting tube 3 and is located between the sealing ring 11 and the magnet 15. The lifting rod 12 moves through the support block 13, and the sealing ring 11 abuts against the support block 13. A spring 16 is sleeved on the lifting rod 12 and is located between the support block 13 and the magnet 15. The two ends of the spring 16 are respectively connected to the support block 13 and the magnet 15. The electromagnet 14 is located between the magnet 15 and the fixed column 4 and is fixedly arranged on the inner wall of the lifting tube 3. The electromagnet 14 and the magnet 15 are arranged opposite each other.

[0038] When the electromagnet 14 is energized, a mutual repulsion force is generated between the electromagnet 14 and the magnet block 15. That is, the magnet block 15 drives the lifting rod 12 to move upward on the support block 13, and causes the spring 16 to deform. The rise of the lifting rod 12 drives the sealing ring 11 to rise, and makes the sealing ring 11 fit with the sealing plate 6. At the same time, the sealing ring 11 blocks the adsorption hole 8. When the electromagnet 14 is de-energized, the elastic force of the spring 16 causes the sealing ring 11 to fall and abut against the support block 13. At this time, the sealing ring 11 blocks the air hole 10.

[0039] The material lifting mechanism is provided in multiple ways, and the multiple material lifting mechanisms are distributed in a matrix. The specific number of the material lifting mechanism is nine.

[0040] In summary, during the lifting process, the frame is adsorbed through the adsorption holes 8, which prevents the frame from continuing to rise under inertia and improves the stability of the lifting process. Moreover, during the descent of the lifting pipe 3, the air inside the lifting pipe 3 is discharged from the air holes 10 and acts on the cutting chamber 2. The impurities generated during the descent and cutting of the frame are blown away by the airflow, which prevents the impurities from causing damage to the frame during subsequent cutting.

[0041] In addition to the above embodiments, this utility model also includes other implementation methods. All technical solutions formed by equivalent transformation or equivalent substitution should fall within the protection scope of the claims of this utility model.
