Description

Technical Field

[0001] This invention relates to the technical field of milling equipment for milk powder caps, specifically to a milling equipment for spiral grooves for reinforcing ribs on milk powder caps. Background Technology

[0002] The milk powder cap is a core component of milk powder packaging. To improve the structural strength, deformation resistance, and screw-on sealing performance of the milk powder cap, an annular reinforcing rib needs to be integrally machined on the inner side of the milk powder cap. During the processing, the reinforcing rib is usually integrally formed with the spiral groove. During processing, the spiral groove is milled into the inner wall of the milk powder cap. After processing is completed, the area that is milled away is the spiral groove, while the continuous protrusions that are not milled and are retained are the spiral annular reinforcing ribs.

[0003] Currently, existing processing equipment has many shortcomings in the processing of spiral grooves for reinforcing ribs on milk powder caps: First, it has poor versatility. Most existing fixtures adopt a fixed structure, which can only be adapted to milk powder caps of a single specification and cannot be adapted to milk powder caps of different diameters. When changing products, it is necessary to frequently change fixtures and tooling, which seriously affects the efficiency of mass production. Second, while the work efficiency is low, the risk factor is high. During the milling process, plastic debris is easy to get stuck inside the milk powder cap. After processing, it is necessary to manually reach under the milling cutter to remove the milk powder cap and pour out the plastic debris. Then, the next milk powder cap can be put in for processing. On the one hand, the high degree of manual intervention increases the workload of workers. On the other hand, the operation under the milling cutter increases the probability of workplace accidents.

[0004] Therefore, it is necessary to provide a new milling machine for spiral grooves to reinforce milk powder caps to solve the above-mentioned technical problems. Summary of the Invention

[0028] In this embodiment, a waste collection vehicle 10 is provided below the flipping mechanism and the debris cleaning component; a conveying and moving component 11 is provided on one side of the waste collection vehicle 10, and four fuma wheels are provided at the bottom of the conveying and moving component 11. It can move to the bottom of the flipping mechanism and loosen the cleaned milk powder cap so that the milk powder cap falls onto the conveying and moving component 11 and is conveyed to the next process.

[0029] In this embodiment, before the entire device is started, a milk powder cap to be processed can be placed in both the first placement tray 301 and the second placement tray 703. The device is not running and there is no mechanical movement, so there is no risk of workplace injury. In the initial state, the milling cutter 405 is coaxial with the first placement tray 301, and the output shaft of the second electric push rod 602 is in the extended state.

[0030] During the clamping operation, the first electric push rod 307 is activated. After activation, its output shaft pushes the first pressure sensor 308 and the connecting spindle 309 upward. The connecting spindle 309 drives the cross-shaped linkage sliding frame 3011 and the abutment bushing 3010 to move upward synchronously. The top of the abutment bushing 3010 has a hemispherical structure. During the upward movement, it fits and squeezes the inclined sides of the four triangular inclined abutment blocks 306, driving the four connecting arms 303 to slide synchronously inward along the guide slide column 302, compressing the return spring 305, so that the four grippers 304 move towards the center synchronously, finally clamping the milk powder cap tightly. During the clamping process... The first protective cotton on the inner side of the gripper 304 can prevent scratching the surface of the milk powder cap during the clamping process. At the same time, the first pressure sensor 308 can detect the clamping pressure in real time and accurately control the clamping force to prevent the milk powder cap from deforming or the clamping from loosening. During the processing, the first servo motor drives the rotating bearing sleeve 3 to rotate through a pair of meshing first spur gears, which in turn drives the first placement plate 301 and the milk powder cap that is clamped and fixed to rotate at a uniform speed, providing a rotary feed basis for the spiral groove annular milling. In addition, the first sliding groove opened on the first placement plate 301 provides a displacement channel for the lateral sliding of the connecting arm 303, ensuring smooth clamping action.

[0031] Subsequently, the lateral position of the milling cutter 405 is adjusted according to the inner diameter of the milk powder cap. During adjustment, simply start the lateral adjustment motor to move the entire milling assembly laterally, completing the precise alignment of the milling cutter 405 to meet the processing requirements of different specifications of milk powder caps. During milling, start the milling motor 401, whose output shaft drives the rotating head 402 to rotate at high speed, thereby driving the bottom milling cutter 405 to rotate synchronously at high speed. The detachable disassembly and assembly structure facilitates the replacement and maintenance of the milling cutter 405 after wear.

[0032] The second servo motor is started, which drives the internal threaded sleeve 5 to rotate through the meshing second spur gear. Based on the thread transmission principle, the vertical feed screw 501 is driven to rise and fall vertically, causing the milling assembly to feed vertically downward. When the milling cutter 405 contacts the inner wall of the milk powder cap, combined with the rotational motion of the milk powder cap itself, the continuous milling of the spiral groove on the inner side of the milk powder cap is precisely completed. In addition, the distance sensor 406 at the bottom of the motor frame 4 can detect the distance between the milling cutter 405 and the bottom inner wall of the milk powder cap in real time, ensuring the accuracy of the milling depth and avoiding collision between the milling cutter 405 and the bottom inner wall of the milk powder cap.

[0033] After the milling of the milk powder cap inside the first placement tray 301 is completed, the output shaft of the first electric push rod 307 is retracted to remove the contact force of the contact bushing 3010 on the triangular inclined contact block 306. Under the action of the return spring 305, the gripper 304 separates from the processed milk powder cap. Then, the first rodless cylinder 604 near the first placement tray 301 is activated to move the corresponding set of fixed clamping rods 606 and movable clamping rods 608 to above the first placement tray 301. At this time, the fixed clamping rods 606 are located above the outer side of the milk powder cap, and the movable clamping rods 608 are aligned with the first placement tray 301 and the milk powder cap. At the same time, the fixed clamping bar 606 located above the second placement plate 703 is positioned above the outer side of the milk powder cap to be processed, and the corresponding movable clamping bar 608 is coaxial with the second placement plate 703. The output shaft of the second electric push rod 602 is retracted, and the two sets of fixed clamping bars 606 and movable clamping bars 608 descend synchronously, so that the two movable clamping bars 608 are respectively inside the milk powder cap that has been processed and the milk powder cap to be processed. Then, the two second rodless cylinders 607 are activated, and the two movable clamping bars 608 move toward their respective fixed clamping bars 606, finally clamping the cap wall of the milk powder cap from the inner and outer walls.

[0034] Subsequently, the output shaft of the second electric push rod 602 is extended to clamp the two milk powder caps. The third servo motor is activated, driving the material steering shaft 6 to rotate via the meshing third sprocket, which in turn rotates the quadrilateral frame 601, causing the two milk powder caps to exchange positions. At this time, the two first rodless cylinders 604 are activated to move the milk powder caps to be processed to directly above the first placement plate 301, and the milk powder caps that have been processed are moved to directly above the second placement plate 703. The output shaft of the second electric push rod 602 is then retracted, placing the processed milk powder caps on the second placement plate 703 and the milk powder caps to be processed on the first placement plate 301. The output shaft of the second electric push rod 602 is then extended to bring the two sets of fixed clamping bars 606 and movable clamping bars 608 back to their original height positions. The first rodless cylinder 604 located above the first placement plate 301 is then activated to retract the corresponding fixed clamping bars 606 and movable clamping bars 608 back to their original positions, ensuring that they do not interfere with the descent of the milling components above.

[0035] Afterwards, the first electric push rod 307 is activated again to clamp the milk powder cap to be processed and continue the milling work; at the same time, the third rodless cylinder 704 is activated, and the processed milk powder cap is clamped by the V-shaped clamping positioning plate 705. No manual intervention is required throughout the process, and the protective cotton sleeve on the outside of the clamping rod can protect the appearance of the milk powder cap.

[0036] When the processed milk powder cap is flipped, the flipping motor drives the workpiece flipping spindle 701 to rotate, which in turn drives the flipping arm 702 and the second placement plate 703 to flip 180°. After the milk powder cap flips with the opening facing down, most of the loose debris inside falls directly into the waste collection vehicle 10 below under the action of gravity.

[0037] For stubborn debris adhering to the inner wall of the milk powder cap, the debris cleaning component is activated: First, the fourth servo motor is started, which drives the rotary U-shaped air guide 901 to rotate through the meshing fourth sprocket, causing the air spray head 904 to rotate directly below the milk powder cap. Then, the high-pressure dust removal fan 9 is started, generating high-pressure airflow, which is introduced into the rotary U-shaped air guide 901 through the air inlet 902 and then poured into the air spray head 904 and sprayed out through the air spray hole 905. During the air spraying process, the output shaft of the third electric push rod 906 is continuously extended and retracted, which pushes the air spray head 904 to move up and down reciprocally. Combined with the high-pressure airflow sprayed circumferentially from the air spray hole 905, the inner wall of the milk powder cap is swept in all directions, and the remaining attached debris is completely blown off. All the debris falls into the waste collection vehicle 10 for collection.

[0038] After the cleaning of the processed milk powder caps is completed, the fourth servo motor is started to rotate the air nozzle 904 back to its original position. Then, the conveying and moving component 11 with the fuma wheel moves flexibly to the underside of the flipping mechanism, and the cleaned milk powder caps are released. The milk powder caps automatically fall onto the conveying and moving component 11 and are conveyed to the next process. Subsequently, the flipping mechanism rotates back to its original position, and the next milk powder cap to be processed is placed on the second placement tray 703. The placement process is not under the milling cutter 405. The operator only needs to place one milk powder cap to be processed on the second placement tray 703 to complete the material preparation. Moreover, the material replenishment station is far away from the working area of ​​the milling cutter 405, so there is no safety hazard.

[0039] After the previous milk powder cap is milled, the material handling assembly operates again to exchange the positions of the processed milk powder cap and the milk powder cap to be processed. The rotation of the material steering shaft 6 can be controlled by the third servo motor to rotate in both directions to form an alternating forward and reverse rotation. After that, the same operation can be continued as described above.

Any equivalent structural or procedural transformations made based on the content of the present invention specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present invention.
