Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following drawings denote similar items; therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings.

[0022] Hopper unit The hopper unit is used to store metal caps to be processed and to initially guide the metal caps so that they fall stably into the conveying unit. Specifically, it includes: Hopper body 3: Made of 304 stainless steel (corrosion resistant and smooth surface to avoid scratching the metal cover), the whole is a rectangular trough structure, with an internal space for accommodating the metal cover, and the upper part of the space is the opening of the hopper body 3, the size of which can be designed according to the production line capacity; the inner sidewalls of the hopper body 3 are all polished to reduce the frictional resistance when the metal cover contacts the sidewalls.

[0023] Inclined part 6: integrally formed on the right side of the upper part of the hopper body 3, with a 45° inclined surface structure. Its top end is flush with the upper right edge of the hopper body 3, and its bottom end extends to the top of the conveyor belt 4 of the conveying unit. When the metal cover is put into the hopper body 3 from the top, the inclined part 6 can guide the metal cover to slowly slide down onto the conveyor belt 4.

[0024] Discharge outlet 7: Located at the bottom of the side wall at the front end of the hopper body 3, it is a rectangular opening structure. Its width is 10-20mm larger than the width of the conveyor belt 4, and its height is 5-10mm larger than the maximum thickness of the metal cover to be conveyed. This ensures that the metal cover can enter the lifting unit from the hopper body 3 individually and smoothly, avoiding stacking. A conventional extension guide plate can also be installed at the discharge outlet 7 to further guide the metal cover to move into the roller 9.

[0025] Insert 8: Located on the top of the side wall at the head end of the hopper body 3, directly above the discharge port 7 (the central axes of the two coincide), it is a rectangular hole structure. Its size matches the cross-section of the input end of the chute 5 (gap ≤ 2mm). The input end of the chute 5 can extend through the insert 8 into the inside of the lifting unit (i.e., inside the drum 9), ensuring that the metal cover falling from the lifting unit can fall accurately into the chute 5 without the risk of material leakage.

[0026] Conveying unit The conveying unit is used to smoothly transport the metal cover inside the hopper body 3 to the lifting unit, providing a stable material supply for the subsequent lifting process. Specifically, it includes: Conveyor belt 4: Made of polyurethane material with anti-slip textured surface to prevent the metal cover from slipping and shifting during transport; the conveying speed of conveyor belt 4 can be adjusted by control center 2 to adapt to different processing capacity requirements.

[0027] Roller assembly: including active roller and driven roller, both made of 45# steel, with a length consistent with the width of conveyor belt 4; the active roller and driven roller are rotatably mounted on the frame at the bottom of the hopper body 3 through bearing seats, and the center distance between them is designed according to the length of the hopper body 3. The conveyor belt 4 is sleeved on the outside of the active roller and driven roller to form a closed-loop conveying structure.

[0028] Power motor: A servo motor is selected and fixed to one side of the frame through a conventional motor mounting bracket; the output shaft of the power motor is connected to one end of the drive roller through a coupling, and can achieve precise speed adjustment and start / stop under the control of the control center 2 to ensure that the conveying speed of the conveyor belt 4 matches the lifting rhythm of the lifting unit and avoid the accumulation of metal covers at the discharge outlet 7.

[0029] The frame is made of square steel welded together. Its top end is fixedly connected to the bottom of the hopper body 3 by bolts, and its bottom end is welded to the surface of the machine body 1. The frame is also equipped with a conveyor belt 4 tensioning structure (conventional adjusting bolts and slider assembly). The tension of the conveyor belt 4 can be adjusted by adjusting the position of the driven roller to avoid the conveyor belt 4 from becoming loose and slipping.

[0030] Lifting Unit The lifting unit is located at the head end of the hopper body 3. It uses the centrifugal force generated by rotation to drive the metal cover to revolve. When the metal cover reaches its highest point, it precisely stops rotating, allowing the metal cover to fall directionally into the chute 5. This is the core structure for achieving collision-free lifting of the metal cover, and specifically includes: Roller 9: Made of 304 stainless steel, the roller has a cylindrical barrel structure. The side of roller 9 facing the outlet 7 is open (the opening diameter is the same as the inner diameter), and the other side is a closed end plate (thickness 10-15mm). The end plate has a shaft hole in the center for installing the drive shaft.

[0031] Anti-slip layer: Made of nitrile rubber, 5-8mm thick, and bonded to the inner circumference of roller 9 with food-grade adhesive; the surface of the anti-slip layer is evenly distributed with hemispherical protrusions (3mm in diameter, 10mm apart), which can increase the friction between the metal cover and the inner wall of roller 9, prevent the metal cover from slipping off due to insufficient centrifugal force when roller 9 rotates, and ensure that the metal cover can rotate synchronously with roller 9.

[0032] Support component 10: includes a main support and an auxiliary support, both made of cast steel; the main support is an L-shaped structure, with its bottom end fixed to the surface of the machine body 1 by a conventional bolt connection, and its top end rotatably connected to the drive shaft of the drum 9 by a deep groove ball bearing; the auxiliary support is a U-shaped structure, located in the middle of the drum 9, with its bottom end welded to the machine body 1, and its top end rotatably connected to the outer circumference of the drum 9 by a self-aligning ball bearing, which can counteract the radial force when the drum 9 rotates, prevent the drum 9 from shifting due to the weight of the metal cover, and ensure that the gap between the opening side of the drum 9 and the first end side wall of the hopper body 3 is stably controlled at 0.5-1mm.

[0033] Drive components include a rotary drive motor, a drive pulley, a driven pulley, and a transmission belt. The rotary drive motor is a servo motor, fixed to the machine body 1 via a motor mounting bracket, located on one side of the main support. The drive pulley is keyed to the output shaft of the rotary drive motor. The driven pulley is connected to the drive shaft of the roller 9 via a coupling, and is rotatably mounted on the main support via a bearing seat. The transmission belt is a polyurethane synchronous belt, sleeved on the outside of the drive pulley and the driven pulley to achieve power transmission. By using a reduction ratio (1:3) between the drive pulley and the driven pulley, the rotational speed of the roller 9 can be controlled at 10-20 r / min, ensuring that the metal cover can rotate smoothly with the roller 9 and avoiding collision damage to the metal cover due to excessive rotational speed.

[0034] Positioning components include a photoelectric sensor and an angle encoder. The photoelectric sensor is installed at the outlet 7 on the side wall of the front end of the hopper body 3 to detect whether the metal cover has entered the drum 9. Its signal output terminal is electrically connected to the control center 2. The angle encoder is installed on the drive shaft of the drum 9 to detect the rotation angle of the drum 9 in real time. Its signal output terminal is also electrically connected to the control center 2. When the photoelectric sensor detects that several metal covers have entered the drum 9, the control center 2 controls the rotation drive motor to start, driving the drum 9 to rotate. When the angle encoder detects that the drum 9 has rotated 170-190° (fine-tuned according to the size of the metal cover to ensure that the metal cover moves to the highest point of the drum 9), the control center 2 immediately controls the rotation drive motor to stop. The metal cover falls vertically into the chute 5 below under the action of gravity, realizing directional material discharge.

[0035] Vibration feeding unit The vibrating feeding unit receives the metal covers dropped from the lifting unit and moves them along the chute 5 via vibration, ultimately conveying them to subsequent processing equipment. The chute 5 is detachable to accommodate metal covers of different specifications, specifically including: Sluice 5: Made of 6061 aluminum alloy, its main conveying structure is a conventional posture screening sluice 5 structure. An extension connecting plate for mating with the intermediate plate is integrally formed on the bottom surface of the middle part. The extension connecting plate has holes for the bolt body 130 to pass through. The input end of sluice 5 extends through the insertion port 8 of the hopper body 3 to the bottom of the roller 9. The output end extends towards the tail end of the hopper body 3 and protrudes from the side wall of the tail end of the hopper body 3 (protrusion length 100-150mm, which facilitates docking with subsequent processing equipment). The inner side wall of sluice 5 is anodized (surface roughness Ra≤0.4μm) to reduce the frictional resistance between the metal cover and the sluice wall, and at the same time improve wear resistance.

[0036] Vibration Generator 11: An electromagnetic vibrator is selected and fixed to the machine body 1 by bolts, located on the left side of the hopper body 3; the vibration frequency of the vibration generator 11 can be adjusted by the control center 2, and the vibration direction is horizontal (consistent with the length direction of the chute 5), ensuring that the vibration force can effectively drive the metal cover to move along the chute 5 to the output end, and avoid the metal cover from bouncing due to up and down vibration.

[0037] Connector 12: includes a vibrating plate and an intermediate plate, both made of Q235 steel plate; one end of the vibrating plate is fixedly connected to the vibration output end of the vibration generating part 11 by bolts, and the other end is fixedly connected to one end of the intermediate plate by bolts; the other end of the intermediate plate is fixedly connected to the extension connecting plate of the chute 5 by bolt connection part 13; the connection part between the vibrating plate and the intermediate plate is also provided with a rubber buffer pad, which can reduce energy loss during vibration transmission and ensure that the vibration generated by the vibration generating part 11 is efficiently transmitted to the chute 5.

[0038] Bolted connection part 13 The bolted connection part 13 is used to achieve a detachable connection between the chute 5 and the intermediate plate, and also has an anti-loosening function to prevent the bolts from loosening due to vibration. Specifically, it includes: Bolt body 130: High-strength bolt is used, and an anti-loosening post 131 is integrally formed at its bottom end. The diameter of the anti-loosening post 131 is smaller than the diameter of the bolt body 130, and the axis of the anti-loosening post 131 coincides with the axis of the bolt body 130.

[0039] Nut 132: A hexagonal nut 132 is used to connect with the bolt body 130 by thread, and is used to clamp and fix the extension connecting plate of the chute 5 to the intermediate plate.

[0040] Anti-loosening bottom cover 133: Made of plastic material, with an overall cylindrical cover structure; the top of the anti-loosening bottom cover 133 has a cavity for the bolt body 130 to pass through, and the bottom has a through hole 134 for the anti-loosening post 131 to pass through; the inner top surface of the anti-loosening bottom cover 133 fits against the lower surface of the nut 132, which can restrict the axial movement of the nut 132.

[0041] Adjusting ring 135: Made of the same plastic material as the anti-loosening bottom cover 133, it has a ring structure with the same inner diameter and outer diameter as the anti-loosening bottom cover 133, and a thickness of 5mm. The number of adjusting rings 135 can be selected according to the gap between the nut 132 and the anti-loosening bottom cover 133. It is used to fill the gap and ensure that the anti-loosening bottom cover 133 can always fit with the nut 132 to achieve reliable anti-loosening. The upper surface of the anti-loosening bottom cover 133 has an annular groove, and the lower surface of the adjusting ring 135 has an annular protrusion that matches the groove. The upper surface of the adjusting ring 135 also has the same groove. The circumferential limit between adjacent adjusting rings 135 is achieved through the cooperation of the groove and the protrusion to prevent the adjusting ring 135 from rotating, thus further improving the anti-loosening effect.

[0042] Anti-loosening metal wire 136: Made of stainless steel wire. The anti-loosening post 131 has a through hole 134 that runs radially through the anti-loosening post 131. After the anti-loosening metal wire 136 passes through the through hole 134, both ends are deformed to prevent it from falling out of the through hole 134, so that the anti-loosening bottom cover 133 cannot be removed, thereby preventing the bolt body 130 from loosening.
