The aluminum foil container is arranged on the periphery of the male die in a sleeving mode, and corresponding impressing lines are arranged between the upper profiling die and the male die. The upper profiling die is far away from the male die in the initial state and the aluminum foil container demolding state, and when the upper profiling die is close to the male die and the aluminum foil container is located between the upper profiling die and the male die, the embossing lines act on the aluminum foil container so that patterns can be embossed on the outer surface of the aluminum foil container, and the profiling uniformity and precision of the aluminum foil container are remarkably improved. And the upper profiling die is far away from the male die in an initial state, so that the aluminum foil container is positioned with the male die in the initial state. Through the matched design of the embossed lines, the pattern embossed lines on the outer surface of the aluminum foil container are consistent, and the problem of pattern blurring caused by traditional single-side profiling is solved. The technical scheme is particularly suitable for impressing complex patterns, and can meet the requirements of consumers on personalized appearances and reduce the defective rate.

Description

Technical Field

[0001] This utility model relates to the technical field of pattern processing for aluminum foil containers, specifically aluminum foil coffee capsule cups, and more specifically to a molding die and mechanical equipment for aluminum foil containers. Background Technology

[0002] In the production of aluminum foil coffee capsule cups, the side-pressing process is crucial. Traditional pressing equipment and methods have many shortcomings. The common method of fixing the cup and pressing down with a mold, due to the special properties of aluminum foil, easily leads to uneven pressing, resulting in blurry, inconsistent patterns, and even foil breakage, resulting in a high product defect rate. At the same time, traditional equipment has low production efficiency, mostly operating at single stations, making it difficult to meet the growing market demand. Furthermore, existing pressing mold designs are relatively simple, unable to achieve complex and diverse pressing effects, failing to meet consumers' pursuit of personalized aluminum foil coffee capsule cups.

[0003] As market demand grows, such as with the popularization of coffee culture, the market demand for aluminum foil coffee capsule cups has increased dramatically. Consumers have increasingly higher requirements for the appearance and design of coffee capsule cups, demanding not only basic functionality but also unique shapes and exquisite patterns. This has prompted coffee capsule cup manufacturers to urgently need efficient, precise, and versatile molding equipment to improve production efficiency, reduce costs, and produce more attractive products.

[0006] The upper die is away from the punch in the initial state and when the aluminum foil container is demolded.

During the pattern imprinting process of the aluminum foil container, the first positioning engagement part is used to maintain the relative positioning between the upper die and the aluminum foil container, and the second positioning engagement part is used to maintain the relative positioning between the upper die and the punch, so as to prevent the upper die and the punch from shifting during the pattern imprinting process of the aluminum foil container.

[0012] The upper die and the lower die are continuously moving and pressing or axially pressing to imprint a pattern on the outer surface of the aluminum foil container. During the continuous moving pressing process, the upper die moves along the outer periphery of the aluminum foil container and cooperates with the lower die to imprint the aluminum foil container. During the axial pressing process, the upper die moves axially along the aluminum foil container and cooperates with the lower die to imprint the aluminum foil container.

[0020] The front positioning device includes a positioning cylinder and a positioning component that is throttle-connected to the piston rod of the positioning cylinder.

[0021] The rear positioning device includes a mold motor and a push cylinder that drives the mold motor to extend and retract.

[0023] The driving device includes a lifting cylinder for driving the upper die of the forming process to move up and down axially, and a transverse driving component for driving the upper die of the forming process and the lifting cylinder to move laterally reciprocating.

[0024] The lateral drive assembly includes a translation motor, a lead screw, and a nut seat sleeved on the outside of the lead screw;

[0025] The machine body is provided with a sliding plate that is fixedly connected to the lifting cylinder. The sliding plate is connected to a translation motor that drives the lead screw to rotate.

[0027] The feeding and conveying device includes a feeding conveyor line and a feeding robot. The feeding conveyor line is used to convey the aluminum foil container with the pattern to be processed toward the feeding robot.

[0028] The loading and unloading conveyor lines are conveyor belts, chains, or roller conveyors, or the loading conveyor line is a vibrating plate;

[0029] Both the loading robot and the unloading robot include a gripping cylinder, a suction cup that is drivenly connected to the piston rod of the gripping cylinder, and a rotary driver fixed on the base.

[0030] The base has a connecting plate on its outer side for fixing the gripping cylinder, and the drive shaft of the rotary driver extends out of the base and is connected to the connecting plate.

[0031] The loading robot grabs an aluminum foil container with the pattern to be processed towards the loading conveyor line.

[0050] The technical solutions of the present utility model will be clearly and completely described below with reference to the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. In order to make the above-mentioned objects, features and advantages of the present application more apparent and understandable, many specific details are set forth in the following description in order to provide a full understanding of the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the spirit of the present application. Therefore, the present application is not limited to the specific embodiments disclosed below.

[0051] See Figure 1-14A forming mold for aluminum foil containers includes an upper forming mold 2 acting on the outer surface of the aluminum foil container 1, and a punch 3 acting on the inner wall of the inner cavity of the aluminum foil container 1; the aluminum foil container 1 is fitted around the outer periphery of the punch 3, and corresponding embossing patterns 4 are provided between the upper forming mold 2 and the punch 3.

[0052] The upper die 2 is away from the punch 3 in the initial state and when the aluminum foil container 1 is demolded. When the upper die 2 and the punch 3 are close together and the aluminum foil container 1 is located between the upper die 2 and the punch 3, the embossing pattern 4 acts on the aluminum foil container 1 to emboss a pattern on the outer surface of the aluminum foil container 1.

[0053] The forming die for the aluminum foil container significantly improves the uniformity and precision of forming the aluminum foil container 1 (aluminum foil coffee capsule cup) through the synergistic action of the upper forming die 2 and the punch 3. The upper forming die 2 is initially positioned away from the punch 3, achieving initial positioning of the aluminum foil container 1 relative to the punch 3. The matching design of the embossing pattern 4 ensures consistency of the embossed pattern 4 on the outer surface of the aluminum foil container 1, solving the problem of pattern blurring caused by traditional single-sided forming. This technical solution is particularly suitable for embossing complex patterns, meeting consumers' demands for personalized appearance while reducing the defect rate.

[0054] The embossing pattern 4 includes a raised pattern 2.1 on the bottom of the upper die 2 and a recessed pattern 3.1 on the outer surface of the punch 3. The raised pattern 2.1 and the recessed pattern 3.1 are in convex-concave fit together to emboss a pattern on the outer surface of the aluminum foil container 1.

[0055] The mating surface between the upper die 2 and the punch 3 is provided with one or more sets of corresponding embossing patterns 4; when the mating surface between the upper die 2 and the punch 3 is provided with two or more sets of embossing patterns 4, each set of embossing patterns 4 may be the same or different, and the raised patterns 2.1 and the concave patterns 3.1 of each set of embossing patterns 4 cooperate with each other during the embossing process of the aluminum foil container 1.

[0056] The embossed texture 4, through the interplay of raised texture 2.1 and recessed texture 3.1, achieves efficient forming of the pattern on the outer surface of the aluminum foil container 1. The design of multiple sets of embossed textures 4 allows for various pattern combinations to be achieved on the same mold, improving production flexibility. When different embossed textures 4 are used, they can be integrated onto the same mold, enabling the embossing of complex patterns in one go, reducing process changeover time and improving production efficiency. The precise alignment of raised texture 2.1 and recessed texture 3.1 ensures the clarity and consistency of the pattern.

[0057] The depth of the convex and concave mating of the raised texture 2.1 and the concave texture 3.1 is t, the inner diameter of the aluminum foil container 1 is D, the outer diameter of the punch 3 is d, and the demolding condition is satisfied: Dd≥2t.

[0058] The design of the demolding conditions, including the depth t of the raised texture 2.1 and the concave texture 3.1, and the inner diameter D of the aluminum foil container 1 and the outer diameter d of the punch 3, effectively solves the demolding problem of the aluminum foil container 1 after stamping. By satisfying the relationship Dd≥2t, it ensures that the stamped aluminum foil material can smoothly detach from the punch 3. This design reduces mechanical stress during demolding and further reduces the risk of aluminum foil breakage. During continuous rolling (continuous movement) stamping, since the punch 3 and the inner cavity of the aluminum foil container 1 are not tightly fitted, the aluminum foil container 1 may experience a small displacement during stamping. However, this displacement can be corrected by adjusting the corresponding coordinate points of the stamping texture 4 between the upper die 2 and the punch 3 to accommodate this displacement. Different patterns require different corrections, which will not be detailed here.

[0059] The upper die 2 is a straight plate structure, an elliptical structure, or a circular structure; the cross-sectional shape of one side of the aluminum foil container 1 is conical, polygonal, or circular, wherein the polygon is a triangle, a square, or a polygon with more than five sides.

[0060] The shapes of the upper die 2 and the punch 3 are designed according to the shape of the aluminum foil container 1.

[0061] A first positioning engagement part 5 is provided between the upper die 2 and the aluminum foil container 1, and a second positioning engagement part 6 is provided between the upper die 2 and the punch 3. During the pattern imprinting process of the aluminum foil container 1, the first positioning engagement part 5 is used to maintain the relative positioning between the upper die 2 and the aluminum foil container 1, and the second positioning engagement part 6 is used to maintain the relative positioning between the upper die 2 and the punch 3, so as to prevent the upper die 2 and the punch 3 from shifting during the pattern imprinting process of the aluminum foil container 1.

[0062] In this embodiment, the first positioning mating part 5 includes a positioning flange provided on the aluminum foil container 1 and a positioning groove provided on the upper die 2. During the pattern imprinting process, the positioning flange of the aluminum foil container 1 is embedded in the positioning groove.

[0063] In this embodiment, the second positioning and mating part 6 includes a positioning ring step provided on the upper die 2 and a positioning ring groove provided on the punch 3. During the pattern imprinting process, the positioning ring step of the aluminum foil container 1 is embedded in the positioning ring groove.

[0064] The first positioning mating part 5 and the second positioning mating part 6, through a dual positioning mechanism, ensure the relative positioning and fit of the upper die 2, the punch 3, and the aluminum foil container 1 during the embossing process. The first positioning mating part 5 prevents relative misalignment between the aluminum foil container 1 and the upper die 2, while the second positioning mating part 6 eliminates the risk of misalignment of the inner upper die, thereby ensuring the accuracy of pattern embossing. This design is particularly suitable for the continuous production of high-precision, complex patterns. The introduction of the positioning structure reduces manual adjustment steps and improves the stability of automated production.

[0065] The upper die 2 and the punch 3 move continuously to imprint or move axially up and down to imprint a pattern on the outer surface of the aluminum foil container 1. During the continuous moving imprinting process, the upper die 2 moves along the outer periphery of the aluminum foil container 1 and cooperates with the punch 3 to imprint the aluminum foil container 1. During the axial imprinting process, the upper die 2 moves axially along the aluminum foil container 1 and cooperates with the punch 3 to imprint the aluminum foil container 1.

[0066] In continuous moving embossing mode, the upper die 2 moves along the outer periphery of the aluminum foil container 1, which is suitable for efficient forming of continuous patterns. In vertical axial embossing mode, after the upper die 2 and the punch 3 cooperate to achieve single-sided embossing, when the aluminum foil container 1 is switched to another position, the upper die 2 and the punch 3 cooperate to continue to emboss the pattern on the aluminum foil container 1. This method can be suitable for embossing patterns 4 with multiple different patterns between the upper die 2 and the punch 3. The switching position of the aluminum foil container 1 can be achieved by a stepper motor, which drives the punch 3 to rotate on the corresponding embossing surface.

[0067] The punch 3 is provided with vents for adsorbing the aluminum foil container 1, and a ventilation channel communicating with the vents and connected to an air pump. The vents are located on the outer surface of the punch 3 that mates with the aluminum foil container 1, and the ventilation channel is located inside the punch 3.

[0068] See Figures 5-14 A mechanical device, comprising a body 7, wherein the body 7 is provided with the above-mentioned forming mold for aluminum foil containers;

[0069] The machine body 7 is equipped with a feeding conveying device 8 for conveying aluminum foil container 1 and conveying aluminum foil container 1 to punch 3;

[0070] The machine body 7 is provided with a driving device 9 for driving the upper mold 2 to move. The driving device 9 is connected to the upper mold 2 in a transmission manner. The upper mold 2 moves through the driving device 9 to realize the imprinting work or demolding action of the aluminum foil container 1.

[0071] The aluminum foil container 1 is cylindrical or conical, and the upper die 2 is plate-shaped.

[0072] The machine integrates molding dies, a feeding and conveying device 8, and a drive device 9 to achieve fully automated stamping production of aluminum foil containers 1 (aluminum foil coffee capsule cups). The modular design of the machine body 7 ensures a highly standardized collaborative process between the upper stamping die 2 and the punch 3, guaranteeing consistency in mass production. This equipment minimizes manual intervention.

[0073] The machine body 7 is provided with a turntable 10, and the turntable 10 is provided with a plurality of circumferentially spaced punches 3. The turntable 10 is provided with a front positioning device 11 and a rear positioning device 12 in the front and rear directions, respectively.

[0074] The front positioning device 11 and the rear positioning device 12 are initially far away from the turntable 10. When the aluminum foil container 1 is imprinted, the front positioning device 11 and the rear positioning device 12 are close to the turntable 10. One end of the front positioning device 11 acts on the aluminum foil container 1, and one end of the rear positioning device 12 acts on the rear of the turntable 10.

[0075] The front positioning device 11 includes a positioning cylinder 13 and a positioning component 14 that is throttle-connected to the piston rod of the positioning cylinder 13.

[0076] The rear positioning device 12 includes a mold motor 12.1 and a push cylinder 12.2 that drives the mold motor 12.1 to extend and retract. A coupling is provided between the rear of each punch 3 and the mold motor 12.1 (the coupling is equivalent to the corresponding punch 3 being set at the rear of the turntable 10). The push cylinder 12.2 drives the mold motor 12.1 to insert into or disengage from the corresponding coupling.

[0077] The coordinated design of the turntable 10 and the front and rear positioning devices 11 and 12 enables multi-station sequential processing and forming. The circumferentially distributed punches 3 allow for sequential operation of the loading, stamping, and unloading processes. The front positioning device 11 fixes the aluminum foil container 1 with the positioning cylinder 13 and positioning component 14. The mold motor 12.1 of the rear positioning device 12 is inserted into the coupling of the punches 3, allowing the mold motor 12.1 to drive the corresponding punches 3 to rotate; that is, each punch 3 is rotatably mounted on the turntable 10. The stepper control of the drive motor 15 enables precise indexing of the turntable 10.

[0078] In this embodiment, the mold motor 12.1 is fixed on the slide of the push cylinder 12.2, and the slide drives the mold motor 12.1 to perform telescopic movements during the telescopic sliding process.

[0079] The turntable 10 is equipped with a drive motor 15 that is connected to it for transmission. The turntable 10 is rotated to the corresponding position angle by the drive motor 15, and the turntable 10 is made to make circumferential stepping motion by the drive motor 15.

[0080] In this embodiment, the drive motor 15 is a servo motor, which is connected to a reducer. A transmission chain is provided on the output shaft of the reducer, and a sprocket connected to the transmission chain is provided on the rotating shaft of the turntable 10. The servo motor can precisely control the speed and torque output. The reducer converts the high-speed rotation of the motor into a low-speed, high-torque rotation suitable for the vertical turntable 10, and then transmits the power to the vertical turntable 10 through the transmission chain, ensuring that the turntable 10 rotates smoothly and accurately to meet the needs of different production rhythms.

[0081] Alternatively, the turntable 10 and the drive motor 15 can be connected by gears or a synchronous belt.

[0082] In this embodiment, a multi-station vertical turntable 10 is vertically mounted on the frame 31. The turntable 10 has multiple punches 3 evenly distributed around its circumference. The punches 3 are detachably mounted on the turntable 10 via connecting columns, and the punches 3 are connected to the connecting columns, which are rotatably connected to the turntable 10. The turntable 10 is made of lightweight, high-strength aluminum alloy and is precision-machined, resulting in a small moment of inertia and high precision. The front positioning device 11 and the rear positioning device 12 adopt an adjustable elastic structure (cylinder) to accommodate aluminum foil coffee cups of different sizes, ensuring that the aluminum foil container 1 (cup) is firmly fixed during the pressing process, without displacement or shaking.

[0083] In this embodiment, the positioning cylinder 13 of the front positioning device 11 is fixed on the connecting seat 32, and the connecting seat 32 is fixed on the rotating shaft extending from the front end of the turntable 10.

[0084] In this embodiment, the rear positioning device 12 is fixed on the rear side of the frame 31. The frame 31 is provided with a fixing plate that is rotatably connected to the turntable 10. The fixing plate 33 is provided with a clearance groove 34 corresponding to the telescopic end of the rear positioning device 12.

[0085] The driving device 9 includes a lifting cylinder 16 for driving the upper die 2 to move up and down axially, and a transverse driving component for driving the upper die 2 and the lifting cylinder 16 to move laterally reciprocatingly.

[0086] The lateral drive assembly includes a translation motor 17, a lead screw 18, and a nut seat 19 sleeved on the outside of the lead screw 18;

[0087] The machine body 7 is provided with a sliding plate 20 fixedly connected to the lifting cylinder 16. The sliding plate 20 is connected to the nut seat 19. The translation motor 17 drives the lead screw 18 to rotate. The nut seat 19 drives the sliding plate 20, the lifting cylinder 16 connected to the sliding plate 20, and the upper die 2 connected to the lifting cylinder 16 to make lateral axial movements.

[0088] The lifting cylinder 16 of the drive device 9 enables the upper die 2 to move closer to or further away from the punch 3 in the vertical axis. When the upper die 2 moves closer to the punch 3, the upper die 2 and the punch 3 cooperate and continuously move to press. During the continuous pressing process, the upper die 2 moves along the outer periphery of the aluminum foil container 1. The movement of the upper die 2 along the outer periphery of the aluminum foil container 1 is achieved by the transverse drive component. During the transverse movement of the upper die 2, and with multiple sets of identical pressing patterns 4 between the upper die 2 and the punch 3, the punch 3 and the aluminum foil container 1 rotate on the turntable 10 as the upper die 2 moves laterally.

[0089] In this embodiment, a fixed plate 35 is provided below the sliding plate 20, and a guide rail 37 is provided on the fixed plate 35. The piston rod of the lifting cylinder 16 is provided with a transmission block 36, and a guide slider 38 that slides with the guide rail 37 is provided on the transmission block 36. During the extension and retraction of the piston rod of the lifting cylinder 16, the guide slider 38 slides on the guide rail 37. The guide rail 37 and the guide slider 38 form a guide assembly. The guide assembly adopts a high-precision linear guide rail and slider to ensure that the lifting cylinder 16 drives the upper die 1 to move along a precise linear direction during operation, avoiding tilting between the punch 3 and the upper die 2, and ensuring the consistency and stability of the forming quality.

[0090] The machine body 7 is provided with a feeding conveying device 21, which includes a feeding conveying line 22 and a feeding robot 23. The feeding robot 23 is used to grab the processed aluminum foil container 1 and convey the processed aluminum foil container 1 to the feeding conveying line 22.

[0091] The feeding conveying device 8 includes a feeding conveying line 24 and a feeding robot 25. The feeding conveying line 24 is used to convey the aluminum foil container 1 with the pattern to be processed toward the feeding robot 25. The feeding robot 25 is used to grab the aluminum foil container 1 on the feeding conveying line 24 and put it onto the punch 3.

[0092] The feeding conveyor line 24 and the unloading conveyor line 22 are conveyor belts, chains, or roller conveyors, or the feeding conveyor line 24 is a vibrating plate;

[0093] Both the loading robot 25 and the unloading robot 23 include a gripping cylinder 26, a suction cup 27 that is connected to the piston rod of the gripping cylinder 26, and a rotary driver 29 fixed on the base 28.

[0094] The base 28 is provided with a connecting plate 30 for fixing the gripping cylinder 26 on the outside, and the drive shaft of the rotary driver 29 extends out of the base 28 and is connected to the connecting plate 30.

[0095] The loading robot 25 grips the aluminum foil container with the pattern to be processed towards the loading conveyor line 24. The gripping cylinder 26 drives the suction cup 27 to move downward towards the loading conveyor line 24. The aluminum foil container 1 is attracted by the suction cup 27. The gripping cylinder 26 resets. The rotary driver 29 runs and drives the connecting plate 30 and the gripping cylinder 26 connected to the connecting plate 30 to rotate towards the punch 3. The gripping cylinder 26 drives the suction cup 27 to move towards the punch 3 to transfer the aluminum foil container 1 onto the punch 3.

[0096] The unloading robot 23 grips the aluminum foil container 1 with the processed pattern towards the punch 3. The rotary driver 29 runs and drives the connecting plate 30 and the gripping cylinder 26 connected to the connecting plate 30 to rotate towards the punch 3. The aluminum foil container 1 on the punch 3 is attracted by the suction cup 27. The gripping cylinder 26 and the rotary driver 29 are reset in sequence. The gripping cylinder 26 drives the suction cup 27 to run towards the unloading conveyor line 22 to transfer the aluminum foil container 1 with the processed pattern to the unloading conveyor line 22.

[0097] The unloading conveyor 21 and the loading conveyor 8 achieve full automation through robotic arms 23 and 25. The vacuum adsorption method of the suction cup 27 avoids mechanical damage to the aluminum foil container 1, and the flipping action of the rotary driver 29 optimizes space utilization. The loading conveyor line 24 and the unloading conveyor line 22 of the conveyor belt or chain ensure the continuous supply and output of the aluminum foil container 1.

[0098] In this embodiment, the punch 3 follows the conical aluminum foil container 1 into a conical shape, and its surface is processed with a die structure that matches the desired molding pattern. This conical design allows the curved surface of the cone to ensure that the side of the aluminum foil coffee cup is evenly stressed at different locations during the molding process, avoiding deformation or breakage of the aluminum foil due to uneven local stress. At the same time, the die structure on the surface can precisely mold various complex molding patterns.

[0099] In this embodiment, the forming working surface of the upper die 2 is flat and has raised ridges. The circumference of the upper die 2 is equal to the bottom circumference of the conical punch 3, so that the upper die and punch fit more precisely during forming. When the upper die 2 presses down, the raised ridges on the flat surface correspond to the concave ridges on the surface of the punch 3, forming the side of the aluminum foil coffee cup. The presence of raised ridges increases the contact pressure and friction between the upper die 2 and the aluminum foil coffee cup, making the formed pattern clearer and deeper, further improving the forming effect.

[0100] In this embodiment, the feeding conveyor 8 is located on one side of the starting station of the vertical turntable 10, and consists of a feeding conveyor line 24 and a feeding robot 25. The feeding conveyor line 24 uses a vibratory feeder or chain conveyor mechanism, which can transport the stacked aluminum foil coffee cups one by one to the gripping position of the feeding robot 25 in an orderly manner. The feeding robot 25 is a multi-joint robotic arm equipped with a high-precision vision recognition system and a vacuum suction cup 27. The vision recognition system can quickly and accurately identify the position and posture of the aluminum foil coffee cups, while the vacuum suction cup 27 uses the principle of negative pressure adsorption to reliably grip the aluminum foil coffee cups and accurately place them on the punch 3 of the vertical turntable 10.

[0101] In this embodiment, the unloading conveyor 21 is located at the end of the vertical turntable 10. The unloading conveyor 21 consists of an unloading robot 23 and an unloading conveyor line 22. The unloading robot 23 has a similar structure to the loading robot 25, but its movements are opposite. It is responsible for removing the aluminum foil coffee cups with completed side molding from the punch 3 of the turntable 10 and placing them onto the unloading conveyor line 22. The unloading conveyor line 22 transports the processed aluminum foil coffee cups to a designated location for subsequent packaging and storage.

[0102] Working process: The product is conveyed by the feeding conveyor 8 to the area below the vacuum suction cup 27 of the feeding robot 25. After the vacuum suction cup 27 of the feeding robot 25 adsorbs the top of the product, the feeding robot 25 rotates to deliver the product to the punch 3 of the turntable 10. The air holes of the punch 3 ensure that the top of the product is in close contact with the top of the punch. The turntable 10 delivers the product once for each rotation step. When the punch 3 rotates to the top of the turntable 10, the upper die 2 moves downward and fits against the product surface. The drive motor 15 starts, and the nut seat 19 drives the sliding plate 20, the lifting cylinder 16 connected to the sliding plate 20, and the upper die 2 connected to the lifting cylinder 16 to make lateral axial movement. The upper die 2 moves forward or backward. At the same time, the mold motor 12.1 drives the punch 3 to rotate to complete the forming. The turntable 10 continues to rotate, and the product is transferred to the corresponding station of the unloading robot 23 suction cup. The unloading robot 23 suction cup picks up the material and sends it to the unloading conveyor line 22. The unloading conveyor line 22 sends it to the packaging station for packaging.

[0103] In this embodiment, the turntable 10 is provided with a boss for each punch 3. The boss is provided with a connector that is connected to the output end (vent hole of the ventilation channel) of each punch 3. The boss is provided with an air extraction channel that is connected to each connector. The air extraction channel is connected to an air pump (not shown in the figure).

[0104] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
