Description

Technical Field

[0001] This application relates to the field of beverage can manufacturing technology, specifically to a beverage can waste conveying and discharging mechanism. Background Technology

[0002] Aluminum cans account for a significant proportion of beverage packaging containers. The manufacture of aluminum cans integrates advanced technologies from many industries such as metallurgy, chemical industry, machinery, electronics, and food, becoming a microcosm of the deep processing of aluminum.

[0003] A beverage can consists of two parts: the can body and the pull-tab lid. The production process of the can body includes coil feeding, coil lubrication, blanking, stretching, can body forming, trimming, cleaning / drying, stacking / unloading, base color coating, drying, color printing, base coating, drying, internal spraying, internal drying, can mouth lubrication, necking, and spin necking. The production process of the pull-tab lid includes pressing aluminum sheets into round discs using a press, then punching and cutting the discs, followed by scoring through a series of molds, further shaping of the pull tab, and finally loading the pull tab onto the lid, ultimately forming a can lid with a pull tab.

[0004] The processes of trimming the tank body, drilling holes in the pull-ring can lid, and cutting all generate waste. The total amount of waste is quite large. To avoid waste and make it recyclable, there are currently mechanisms that transport waste through pipelines. Waste is collected at the workstations where it is generated and transported through pipelines to the waste collection box. However, there are many strip-shaped pieces of waste generated from trimming. During the transportation process, these pieces of waste become entangled and clump together. Eventually, multiple clumps of waste accumulate at the discharge end, causing blockage. Forcibly pulling them out can easily damage the pipeline at the discharge end. Utility Model Content

[0005] Therefore, there is a need to provide a material conveying and discharging mechanism for aluminum can waste to solve the problem in the existing technology where strip-shaped waste from aluminum cans continuously entangles and clumps together during pipeline conveying, resulting in multiple clumps of waste clogging the discharge end, and forcibly clearing the blockage and pulling it out will damage the pipeline.

[0006] To achieve the above objectives, the inventors provide a waste can conveying and discharging mechanism, comprising:

[0007] The conveying pipe is used to convey waste materials;

[0008] The discharge hopper has a dual-shaft shredding mechanism inside to shred waste materials; the top surface of the discharge hopper has a feed inlet connected to the other end of the output pipe; the bottom surface of the discharge hopper has a discharge outlet; the side of the discharge hopper has a negative pressure port, the height of which is higher than the height of the dual-shaft shredding mechanism, and the negative pressure port is equipped with a filtering mechanism.

[0009] A vacuum assembly is connected to the negative pressure port of the discharge hopper to draw waste material from the conveying pipe into the discharge hopper under negative pressure.

[0010] A screw feeder, wherein the feed inlet of the screw feeder is connected to the discharge outlet of the discharge hopper, and the screw feeder is equipped with an electrostatic eliminator inside to eliminate static electricity.

[0011] In some embodiments, the vacuum assembly includes a vacuum blower and a vacuum chamber, with the negative pressure port of the discharge hopper, the vacuum chamber, and the vacuum blower connected in sequence.

[0012] In some embodiments, the screw feeder includes a housing, a screw, blades, and a motor. The screw is rotatably and laterally disposed within the housing, and the blades are spirally wound around the side wall of the screw. The motor is connected to the screw in a drive system.

[0013] In some embodiments, the helical spacing of the blades gradually decreases along the discharge direction.

[0014] In some embodiments, the sidewall of the housing is provided with a transparent observation window.

[0015] In some embodiments, the inner wall of the housing is provided with a stainless steel layer, and the surface of the blade is provided with a ceramic layer.

[0016] In some embodiments, the inner wall of the housing is provided with a pressure detection mechanism; the motor is a variable frequency motor;

[0017] Also includes:

[0018] The control unit is connected to the variable frequency motor and the pressure detection mechanism to receive the detection value of the pressure detection mechanism and control the variable frequency motor to change speed.

[0019] In some embodiments, the control unit is also connected to the vacuum assembly to control the vacuum assembly.

[0020] In some embodiments, the static eliminator is an inductive static eliminator.

[0021] Unlike existing technologies, the can waste conveying and discharging mechanism described in the above technical solution connects the conveying pipe to the discharge end of an existing waste conveying pipe, thereby connecting the waste conveying pipe to the can waste conveying and discharging mechanism of this application. The can waste conveying and discharging mechanism of this application provides auxiliary discharge. The top surface of the discharge hopper has an inlet, which is connected to the other end of the output pipe. Waste conveyed to the conveying pipe can be conveyed to the discharge hopper. A negative pressure port is located on the side of the discharge hopper, and a vacuum assembly is connected to the negative pressure port of the discharge hopper, providing power to draw the waste from the conveying pipe into the discharge hopper under negative pressure. Because the discharge hopper of the can waste conveying and discharging mechanism has a dual-shaft shredding mechanism inside, it can crush strip-shaped waste or tangled waste, thereby crushing the tangled waste and strip-shaped waste continuously formed during conveying, preventing blockages. Furthermore, the... The negative pressure port is located at a higher height than the biaxial shredding mechanism. After passing through the biaxial shredding mechanism, the waste is shredded. The shredded waste is then isolated from the negative pressure port by the biaxial shredding mechanism. Therefore, using a biaxial shredding mechanism as the shredding mechanism prevents waste particles from being drawn into the vacuum assembly. Furthermore, the negative pressure port is equipped with a filter mechanism, which further prevents particulate impurities from entering the vacuum assembly, ensuring its service life. The bottom of the discharge hopper has a discharge port, and the inlet of the screw feeder is connected to the discharge port of the discharge hopper. The shredded waste is discharged orderly through the screw feeder, which further agitates the waste, preventing it from clumping due to moisture. The entire discharge process is smoother. The screw feeder is equipped with an electrostatic eliminator to eliminate static electricity, preventing the shredded waste from adsorbing onto the inside of the screw feeder due to static electricity generated by friction, thus avoiding blockage caused by static adsorption. Therefore, the can waste conveying and discharging mechanism, as the discharge end of the waste conveying pipeline, can assist the pipeline in discharging waste, avoid the accumulation of multiple clumps of waste, and ensure smooth discharge at the discharge end.

[0053] Aluminum cans account for a significant proportion of beverage packaging containers. The manufacture of aluminum cans integrates advanced technologies from many industries such as metallurgy, chemical industry, machinery, electronics, and food, becoming a microcosm of the deep processing of aluminum.

[0054] A beverage can consists of two parts: the can body and the pull-tab lid. The production process of the can body includes coil feeding, coil lubrication, blanking, stretching, can body forming, trimming, cleaning / drying, stacking / unloading, base color coating, drying, color printing, base coating, drying, internal spraying, internal drying, can mouth lubrication, necking, and spin necking. The production process of the pull-tab lid includes pressing aluminum sheets into round discs using a press, then punching and cutting the discs, followed by scoring through a series of molds, further shaping of the pull tab, and finally loading the pull tab onto the lid, ultimately forming a can lid with a pull tab.

[0055] The processes of trimming the tank body, drilling holes in the pull-ring can lid, and cutting all generate waste. The total amount of waste is quite large. To avoid waste and make it recyclable, there are currently mechanisms that transport waste through pipelines. Waste is collected at the workstations where it is generated and transported through pipelines to the waste collection box. However, there are many strip-shaped pieces of waste generated from trimming. During the transportation process, these pieces of waste become entangled and clump together. Eventually, multiple clumps of waste accumulate at the discharge end, causing blockage. Forcibly pulling them out can easily damage the pipeline at the discharge end.

[0056] Therefore, this utility model provides a waste can conveying and discharging mechanism for assisting in the discharge of waste through pipelines, especially for breaking up clumps of waste, thereby preventing the waste from continuously tangling and clogging at the outlet of the pipeline and ensuring smooth discharge of the waste.

[0057] Please see Figure 1 In a specific embodiment, the can waste conveying and discharging mechanism includes a conveying pipe 1, a discharge hopper 2, a vacuum assembly, and a screw feeder 4.

[0058] The conveying pipe 1 is used to convey waste materials; please refer to... Figure 3 The discharge hopper 2 is equipped with a dual-shaft shredding mechanism 3 to shred waste materials; please refer to [link / reference]. Figure 2 The top surface of the discharge hopper 2 is provided with a feed inlet, which is connected to the other end of the output pipe; the bottom surface of the discharge hopper 2 is provided with a discharge outlet; the side surface of the discharge hopper 2 is provided with a negative pressure port 202, which is located at a height higher than that of the dual-shaft shredding mechanism 3, and the negative pressure port 202 is provided with a filter mechanism; the vacuum component is connected to the negative pressure port 202 of the discharge hopper 2 to extract waste material from the conveying pipe 1 into the discharge hopper 2 under negative pressure; the feed inlet of the screw feeder 4 is connected to the discharge outlet 201 of the discharge hopper, and the screw feeder 4 is provided with an electrostatic eliminator inside to eliminate static electricity.

[0059] The can waste conveying and discharging mechanism is connected to the discharge end of an existing waste conveying pipeline via a conveying pipe 1, so as to connect the waste conveying pipeline with the can waste conveying and discharging mechanism of this application, and to perform auxiliary discharge through the can waste conveying and discharging mechanism of this application.

[0060] The top surface of the discharge hopper is provided with a feed inlet. The feed inlet 200 of the discharge hopper is connected to the other end of the output pipe. The waste material conveyed to the conveying pipe 1 can be conveyed to the discharge hopper 2. The side of the discharge hopper 2 is provided with a negative pressure port 202. The vacuum component is connected to the negative pressure port 202 of the discharge hopper, thereby providing power to draw the waste material from the conveying pipe 1 into the discharge hopper 2 under negative pressure.

[0061] Because the discharge hopper 2 of the aluminum can waste conveying and discharging mechanism is equipped with a dual-shaft shredding mechanism 3, it can crush strip-shaped waste or tangled waste, thereby crushing the tangled waste and strip-shaped waste that are continuously formed during the conveying process and avoiding blockage; in addition, the height of the negative pressure port 202 is higher than the height of the dual-shaft shredding mechanism 3. After the waste passes through the dual-shaft shredding mechanism 3, it is crushed. The crushed waste is isolated from the negative pressure port 202 by the dual-shaft shredding mechanism 3. Therefore, using the dual-shaft shredding mechanism 3 as the crushing mechanism can prevent waste particles from being drawn to the vacuum component. Moreover, the negative pressure port 202 is equipped with a filter mechanism, which can further prevent particulate impurities from entering the vacuum component and ensure the service life of the vacuum component.

[0062] The bottom surface of the discharge hopper 2 is provided with a discharge port. The feed inlet 4001 of the screw feeder is connected to the discharge outlet 201 of the discharge hopper. The crushed waste is discharged in an orderly manner through the screw feeder 4. The screw feeder 4 can further agitate the waste to prevent the crushed waste from clumping due to moisture, making the entire discharge process smoother. The screw feeder 4 is equipped with an electrostatic eliminator to eliminate static electricity, which can prevent the crushed waste from being attracted to the inside of the screw feeder 4 due to static electricity generated by friction, thus avoiding blockage due to static electricity adsorption.

[0063] Therefore, the can waste conveying and discharging mechanism, as the discharge end of the waste conveying pipeline, can assist the pipeline in discharging waste, avoid the accumulation of multiple clumps of waste, and ensure smooth discharge at the discharge end.

[0064] In some embodiments, the interior of the discharge hopper is divided into an independent upper cavity and a lower cavity by the dual-shaft shredding mechanism 3. The feed inlet and the negative pressure port 202 of the discharge hopper are located in the upper cavity, and the discharge outlet of the discharge hopper is located in the lower cavity. The waste material entering the discharge hopper first enters the upper cavity, is shredded by the dual-shaft shredding mechanism 3, and then enters the lower cavity. It is discharged from the discharge outlet of the discharge hopper into the screw feeder 4. The shredded waste material is not drawn back into the upper cavity by the negative pressure, nor is it drawn into the negative pressure assembly by the negative pressure.

[0065] Please see Figure 4 and Figure 5 In some embodiments, the vacuum assembly includes a vacuum blower 5 and a vacuum box 6. The negative pressure port 202 of the discharge hopper, the vacuum box 6, and the vacuum blower 5 are connected in sequence. The vacuum blower 5 forms a stable suction in the vacuum box 6 to suck the waste material in the pipeline into the discharge hopper 2.

[0066] In some embodiments, the screw feeder 4 includes a housing 400, a screw 401, blades 402, and a motor 403. The screw 401 is rotatably and laterally disposed within the housing 400, and the blades 402 are spirally wound around the side wall of the screw 401. The motor 403 is connected to the screw 401 in a transmission connection.

[0067] In some embodiments, the two ends of the screw 401 are rotatably disposed within the housing 400 via bearings.

[0068] In some embodiments, the motor 403 is connected to one end of the screw 401 via a coupling to drive the screw 401 to rotate.

[0069] In some embodiments, the outer casing is tubular, and the screw 401 is arranged along the axial direction of the tubular outer casing. The feed inlet 4001 and discharge outlet 4002 of the screw feeder are both located within the outer casing. The feed inlet 4001 is located on the side wall of the outer casing; the discharge outlet 4002 can also be located on the side wall of the outer casing, or it can be located on one end face of the outer casing. Furthermore, the feed inlet 4001 and discharge outlet 4002 of the screw feeder are arranged sequentially along the axial direction of the outer casing. After the waste material enters the outer casing through the feed inlet 4001, it is gradually moved to the discharge outlet 4002 of the screw 401 under the drive of the blades 402, thus completing the discharge. This discharge method allows for uniform discharge and avoids material jamming.

[0070] In some embodiments, the helical spacing of the blades 402 gradually decreases along the discharge direction, thereby gradually reducing the waste material conveyed by the screw feeder 4, controlling the amount of waste material reaching the discharge port 4002 of the screw feeder, and ensuring that the discharge is not blocked.

[0071] Please see Figure 4 In some embodiments, the side wall of the housing 400 is provided with a transparent observation window 4000, which makes it easy to see the working conditions inside the screw feeder 4, and to detect abnormalities in a timely and intuitive manner for maintenance.

[0072] In some embodiments, the inner wall of the housing 400 is provided with a stainless steel layer to reduce the coefficient of friction with aluminum and the risk of adhesion; the surface of the blade 402 is provided with a ceramic layer for greater wear resistance.

[0073] In some embodiments, the inner wall of the housing 400 is provided with a pressure detection mechanism; the motor 403 is a variable frequency motor; and a control unit is also included, which is connected to the variable frequency motor and the pressure detection mechanism to receive the detection value of the pressure detection mechanism and control the variable frequency motor to change speed. When the detection value detected by the pressure detection mechanism is greater than a preset value, the discharge speed is slow and the waste material accumulates in the screw feeder 4. The control unit can then control the variable frequency motor to increase its speed, thereby speeding up the discharge of waste material and alleviating the blockage.

[0074] In some embodiments, the control unit is also connected to the vacuum assembly to control the vacuum assembly, wherein the vacuum fan 5 of the vacuum assembly is a variable frequency fan. When the detection value detected by the pressure detection mechanism is greater than the preset value, the discharge speed is slow and the amount of waste in the discharge hopper 2 is too large. In order to alleviate the accumulation of waste in the screw feeder 4, the control unit controls the speed of the variable frequency fan of the vacuum assembly to reduce the speed of the variable frequency fan, thereby slowing down the speed of the waste entering the discharge hopper 2 and reducing the amount of waste entering the discharge hopper 2 to alleviate the blockage.

[0075] In some embodiments, the static eliminator is an inductive static eliminator, consisting of a metal discharge needle, a grounding electrode, and an induction ring, and requires no external power supply.

[0076] Finally, it should be noted that although the above embodiments have been described in the text and drawings of this application, this should not limit the scope of patent protection of this application. Any technical solutions that are based on the essential concept of this application and utilize the content described in the text and drawings of this application, resulting in equivalent structural or procedural substitutions or modifications, as well as the direct or indirect application of the technical solutions of the above embodiments to other related technical fields, are all included within the scope of patent protection of this application.
