[0002] In the production process of metal packaging barrel end caps, the existing technology usually uses punch press to cut discs. This method has significant difficulties in adjusting the size specifications. Whenever it is necessary to produce discs of different diameters or thicknesses, it is necessary to change the corresponding special mold. The manufacturing cost of each set of molds is as high as tens of thousands of yuan, which leads to long production preparation cycle, low equipment utilization rate, and frequent mold changes not only increase the intensity of manual operation, but also easily cause equipment wear and positioning errors, affecting the consistency of products and processing accuracy, and further limiting the flexibility of the production line and the ability to produce small batches of multiple specifications.

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0021] Please see Figure 1-9 This invention provides a technical solution: an automatic forming equipment for metal packaging barrel end caps, comprising a feeding platform 1, a leveling machine 2, a laser disc cutter 3, a disc palletizer 4, and a waste material palletizer 5 arranged sequentially. The feeding platform 1 is connected to the leveling machine 2 for conveying metal sheets. The leveling machine 2 is connected to the laser disc cutter 3 for conveying the leveled metal sheets. The laser disc cutter 3 is connected to the disc palletizer 4 for conveying the cut discs. The laser disc cutter 3 is connected to the waste material palletizer 5 for discharging the waste generated during cutting. The machine 3 includes a switching mechanism 31 for alternating use and a maintenance mechanism for cooling and cleaning the laser head 31-5 after use. The switching mechanism 31 is used to realize the automatic alternation of the two laser heads 31-5 in a standby state to ensure that the laser cutting process is continuous and uninterrupted. The maintenance mechanism is responsible for rapidly cooling down the laser head 31-5 after use and cleaning the nozzle of the laser head 31-5 to maintain the stable working state of the laser head 31-5, extend its service life, and reduce the decrease in processing accuracy caused by overheating or contamination.

[0022] Specifically, the switching mechanism 31 includes a supporting shell 31-1, two annular grooves 31-2, a rotating disk 31-3, a drive motor 31-4, and two laser heads 31-5. The bottom of the supporting shell 31-1 is an open structure. The two annular grooves 31-2 are fixedly installed on the left and right sides inside the supporting shell 31-1, respectively. The rotating disk 31-3 is slidably connected to the two annular grooves 31-2. The annular grooves 31-2 are used to support the rotating disk 31-3, which can rotate within the annular grooves 31-2. The drive motor 31-4 is fixedly installed on the top of the supporting shell 31-1. The drive end of the drive motor 31-4 extends through the top of the supporting shell 31-1 and is fixedly connected to the top of the rotating disk 31-3. The two laser heads 31-5 are fixedly installed on the bottom of the rotating disk 31-3 and are symmetrically distributed at 180 degrees. The drive end of the drive motor 31-4 rotates 180 degrees each time, realizing precise switching between the two laser heads 31-5. Since the two laser heads 31-5 are symmetrically distributed at 180 degrees on the rotating disk 31-3, when the drive motor 31-4 rotates 180 degrees, the laser head 31-5 that was originally in the working position will move to the maintenance mechanism, while the laser head 31-5 that was originally in the maintenance mechanism will be accurately brought into the working position, thus realizing the one-to-one switching between the two laser heads 31-5.

[0023] Specifically, the maintenance mechanism is fixedly installed on one side of the support housing 31-1, and the maintenance mechanism corresponds to one of the laser heads 31-5. The maintenance mechanism includes a dynamic air-cooling structure for cooling the laser head 31-5 and a cleaning structure 36 for cleaning the nozzle of the laser head 31-5.

[0024] Specifically, the dynamic air-cooling structure includes a lifting unit 32 for comprehensively cooling the laser head 31-5 after use, a rotary jet unit 33, an execution unit 34 for simultaneously driving the lifting unit 32 and the rotary jet unit 33, and an air supply unit 35 for supplying air to the rotary jet unit 33. The lifting unit 32 includes a fixed base 32-1, an electric telescopic rod 32-2, a bracket 32-3, a connecting base 32-4, a transmission box 32-5, a reciprocating screw 32-6, a limiting guide rod 32-7, and a slider 32-8. The fixed base 32-1 is fixedly installed on one side of the supporting shell 31-1, and the electric telescopic rod 32-2 is fixedly installed at the bottom of the fixed base 32-1. The bracket 32-3 is connected to the electric telescopic rod via the connecting base 32-4. The drive end of 32-2 is fixedly connected, the transmission box 32-5 is fixedly set at the bottom of the bracket 32-3, the two ends of the reciprocating screw 32-6 are rotatably connected to the top of the bracket 32-3 and the top and bottom of the transmission box 32-5 respectively, the limiting guide rod 32-7 is fixedly set between the inner top of the bracket 32-3 and the outer top of the transmission box 32-5, the slider 32-8 is provided with a spiral cam that cooperates with the spiral groove of the reciprocating screw 32-6, and the slider 32-8 is movably connected to the reciprocating screw 32-6. The slider 32-8 is also slidably connected to the limiting guide rod 32-7. The execution unit 34 is connected to the reciprocating screw 32-6, the rotary jet unit 33 is connected to the slider 32-8, and the rotary jet unit 33 is also connected to the execution unit 34.

[0025] The electric telescopic rod 32-2 can control the vertical displacement of the lifting unit 32 and the rotating jet unit 33, thereby enabling the cooling and cleaning of the laser head 31-5. When the laser head 31-5 completes its cutting task and rotates to the maintenance position, the electric telescopic rod 32-2 is activated, pushing the bracket 32-3, connecting seat 32-4, and all components thereon upwards. This allows the rotating jet unit 33 to approach the laser head 31-5, providing comprehensive cooling and nozzle cleaning. After cleaning, the electric telescopic rod 32-2 reverses its movement, smoothly resetting the lifting unit 32 and the rotating jet unit 33 to their initial low positions. This ensures that the rotating jet unit 33 will not interfere with the next rotation switch of the laser head 31-5, thus achieving precise connection between the maintenance process and the rotation switch of the laser head 31-5, ensuring the continuity and stability of equipment operation. During the rotation of the reciprocating screw 32-6, the spiral cam, guided by the spiral groove, drives the slider 32-8 to reciprocate up and down along the direction of the limiting guide rod 32-7, thereby achieving vertical displacement of the rotating jet unit 33 and improving the overall cooling effect.

[0026] Specifically, the rotary jet unit 33 includes a support box 33-1, an annular slide rail 33-2, two moving blocks 33-3, a drive gear 33-4, an annular jet cylinder 33-5, and multiple jet pipes 33-6. The support box 33-1 is fixedly mounted on the moving blocks 33-3, and corresponding through holes are provided at the top and bottom of the support box 33-1. The annular slide rail 33-2 is fixedly mounted inside the top of the support box 33-1. The two moving blocks 33-3 are slidably connected to the annular slide rail 33-2. The drive gear 33-4 is fixedly mounted at the bottom of the two moving blocks 33-3. -4 can rotate within the annular slide rail 33-2 via the movable block 33-3. The annular jet tube 33-5 is fixedly installed on the inner wall of the drive gear 33-4, and multiple jet pipes 33-6 are fixedly installed on the annular jet tube 33-5. The drive gear 33-4, the annular slide rail 33-2, the through hole, and the center of the annular jet tube 33-5 are all located on the same vertical axis. The drive gear 33-4, the annular slide rail 33-2, the through hole, and the hollow part inside the annular jet tube 33-5 are all sleeved on the outside of the laser head 31-5. The gas supply unit 35 is connected to the annular jet tube 33-5.

[0027] During operation, the execution unit 34 drives the drive gear 33-4 to rotate, which in turn drives the annular jet tube 33-5 and the jet pipe 33-6 to rotate together. This allows the multiple jet pipes 33-6 to cool the laser head 31-5 from multiple angles and in all directions. When used in conjunction with the lifting unit 32, the annular jet tube 33-5 and the jet pipe 33-6 can move up and down while rotating, thereby providing comprehensive and rapid cooling for the laser head 31-5.

[0028] Specifically, the execution unit 34 includes an execution motor 34-1, a multi-stage telescopic rod 34-2, a first transmission gear 34-3, a second transmission gear 34-4, and a driven gear 34-5. The execution motor 34-1 is fixedly mounted on the bottom of the transmission box 32-5, and its drive end is fixedly connected to the bottom end of the reciprocating screw 32-6. The execution motor 34-1 directly drives the reciprocating screw 32-6. The multi-stage telescopic rod 34-2 is rotatably connected to the top and bottom of the transmission box 32-5 and the support box 33-1, respectively. The first transmission gear 34-3 is fixedly mounted on the reciprocating screw 32-6. The second transmission gear 34-4 is fixedly mounted on the outer wall of the first section of the multi-stage telescopic rod 34-2. The driven gear 34-5 is fixedly mounted on the multi-stage telescopic rod 34-2. On the outer wall of the last section, the driven gear 34-5 meshes with the driving gear 33-4. The actuator 34-1 drives the first transmission gear 34-3 to rotate via the reciprocating screw 32-6, which in turn transmits the driving force to the multi-stage telescopic rod 34-2 via the second transmission gear 34-4, causing it to rotate as a whole. The multi-stage telescopic rod 34-2 then drives the driven gear 34-5 to rotate, thereby driving the driving gear 33-4 and the internal annular jet cylinder 33-5 to rotate together. As an existing device, the multi-stage telescopic rod 34-2 ensures that no matter what position the rotating jet unit 33 is raised or lowered by the lifting unit 32, the driving force of the actuator 34-1 can be stably transmitted to the driving gear 33-4, thereby realizing the continuous rotation function of the rotating jet unit 33 during the lifting process.

[0029] Specifically, the air supply unit 35 includes two bases 35-1, an annular transfer cylinder 35-2, an outer ring 35-3, an inner ring 35-4, and an air inlet pipe 35-5. The two bases 35-1 are fixedly installed at the bottom of the support box 33-1, and the annular transfer cylinder 35-2 is fixedly installed at the top of the two bases 35-1. An annular exhaust port is opened at the top of the annular transfer cylinder 35-2. The outer ring 35-3 and the inner ring 35-4 are coaxially nested and fixedly installed inside the annular exhaust port. The outer ring 35-3 and the inner ring 35-4 form an annular airflow channel, and the annular airflow channel is connected to the annular transfer cylinder 35-2 through the annular exhaust port. An annular air inlet groove is opened at the bottom of the drive gear 33-4. The outer ring 35-3 and the inner ring 35-4 are movably inserted into the top to form a rotatable gas-sealed communication channel, allowing gas to flow from the annular transfer cylinder 35-2 through the gap between the outer ring 35-3 and the inner ring 35-4 into the annular air intake groove of the drive gear 33-4. The air intake pipe 35-5 is fixedly inserted through the bottom of the support box 33-1, and one end of the air intake pipe 35-5 is fixedly connected to the annular transfer cylinder 35-2. The other end of the air intake pipe 35-5 is connected to an external air source to introduce the external air source into the annular transfer cylinder 35-2. Then, through the annular airflow channel and the annular air intake groove, a stable airflow is continuously provided to the rotating jet unit 33, realizing the dynamic transmission of gas between the rotating and non-rotating parts.

[0030] Specifically, the cleaning structure 36 includes a rotating shaft 36-1, a cleaning brush 36-2, a first sprocket 36-3, a second sprocket 36-4, and a chain 36-5. The rotating shaft 36-1 is rotatably connected to the top and bottom of the support box 33-1, respectively. The cleaning brush 36-2 is fixedly mounted on the rotating shaft 36-1. The first sprocket 36-3 and the second sprocket 36-4 are respectively fixedly mounted on the outer wall of the first section of the multi-stage telescopic rod 34-2 and on the rotating shaft 36-1. The first sprocket 36-3 and the second sprocket 36-4 are connected by the chain 36-5. When the multi-stage telescopic rod 34-2 rotates under the drive of the execution unit 34, the first sprocket 36-3 rotates accordingly and transmits the rotational power to the second sprocket 36-4 through the chain 36-5, thereby driving the rotating shaft 36-1 and the cleaning brush 36-2 to rotate together, thereby cleaning the nozzle of the laser head 31-5.

[0031] Specifically, rubber rings are fixedly installed at the parts of the outer ring 35-3 and the inner ring 35-4 that contact the annular air inlet groove to improve the sealing performance during the air source transportation process.

[0032] Specifically, the laser disc cutting machine 3 also includes a three-dimensional moving mechanism 37, which is connected to the switching mechanism 31. The three-dimensional moving mechanism 37 is an existing component of the laser cutting machine in the prior art, and it can drive the switching mechanism 31 to move in three dimensions.

[0033] Working principle: After the equipment is started, the metal sheet is first fed into the leveling machine 2 through the feeding platform 1. The leveling machine 2 flattens the sheet through multiple sets of rollers to eliminate internal stress and ensure its flatness, which is convenient for subsequent laser cutting. The leveled sheet is then transported to the laser disc cutter 3. The laser disc cutter 3 drives the switching mechanism 31 to be precisely positioned and moved in three-dimensional space through the three-dimensional moving mechanism 37. The drive motor 31-4 in the switching mechanism 31 drives the rotating disc 31-3 to rotate in the annular slide 31-2, realizing the automatic alternation of the two laser heads 31-5, one in standby and one in use. When one laser head 31-5 completes the cutting task, the rotating disc 31-3 rotates 180 degrees to move the laser head 31-5 to the maintenance station, while the other laser head 31-5 is brought into the cutting station to continue working, ensuring that the laser cutting process is continuous and uninterrupted.

[0034] At the maintenance station, when the laser head 31-5 completes its cutting task and rotates to the maintenance position, the electric telescopic rod 32-2 is activated, pushing the bracket 32-3, connecting seat 32-4, and all its components upwards. This causes the through hole of the rotating jet unit 33 to fit over the laser head 31-5, and the cleaning brush 36-2 inside the cleaning structure 36 enters the nozzle of the laser head 31-5. During this process, the execution motor 34-1 in the execution unit 34 drives the reciprocating screw 32-6 to rotate, transmitting power to the multi-stage telescopic rod 34-2 via the first transmission gear 34-3 and the second transmission gear 34-4, causing it to rotate. The multi-stage telescopic rod 34-2 drives the driven gear 34-5 to rotate, which in turn drives the driving gear 33-4 and the internal annular jet cylinder 33-5 to rotate. The jet pipe 33-6 then rotates the laser head 31-5 at multiple angles. Cooling; simultaneously, during the rotation of the reciprocating screw 32-6, the spiral cam inside the slider 32-8 moves up and down along the direction of the limiting guide rod 32-7 under the guidance of the spiral groove, thereby realizing the vertical displacement of the rotating jet unit 33 and improving the overall cooling. The air supply unit 35 introduces the external air source into the annular transfer cylinder 35-2 through the air inlet pipe 35-5, and flows into the annular air inlet groove of the drive gear 33-4 through the annular airflow channel between the outer ring 35-3 and the inner ring 35-4, forming a rotatable gas sealed communication channel to ensure stable airflow delivery; when the multi-stage telescopic rod 34-2 rotates, the cleaning structure 36 drives the cleaning brush 36-2 on the rotating shaft 36-1 to rotate through the first sprocket 36-3, the second sprocket 36-4 and the chain 36-5 to clean the nozzle of the laser head 31-5 to prevent blockage and contamination.

[0035] After cleaning and cooling are completed, the electric telescopic rod 32-2 reverses its movement, smoothly resetting the lifting unit 32 and the rotating jet unit 33 to their initial low positions. This ensures that the rotating jet unit 33 will not interfere with the next rotation switch of the laser head 31-5, thereby achieving precise connection between the maintenance process and the rotation switch of the laser head 31-5.

[0036] The three-dimensional moving mechanism 37 continuously adjusts the spatial position of the laser head 31-5 to ensure accurate cutting trajectory; the cut discs are transported to the disc stacker 4 for stacking, and the waste generated from cutting is transported to the waste stacker 5 for centralized processing. The entire process achieves fully automated continuous production, greatly improving production efficiency and processing accuracy.

[0037] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
