Description

Technical Field

[0001] This invention relates to the field of packaging can manufacturing technology, and in particular to a waste recycling device for the production process of easy-open lids for metal packaging cans. Background Technology

[0002] Easy-open lids, also known as pull-tab lids, are metal packaging products used to seal canned goods. They are typically made of aluminum or tinplate and come in various sizes, suitable for iron cans, aluminum cans, composite cans, PET plastic cans, and paper cans. Easy-open lids are used for metal cans in the food canning industry. The process of making easy-open lids includes: sheet metal → base lid forming → pull-tab assembly → post-processing → imaging visual inspection → assembly packaging. Easy-open lids are broadly classified into round and non-round shapes. Irregularly shaped easy-open lids refer to non-circular easy-open lids, such as oval, square, and horseshoe shapes. Easy-open lids are used for sealing and opening cans; they are defined as lids with pre-engraved grooves of a certain depth and riveted pull tabs that can be safely torn open along the grooves. They are also a good type of anti-counterfeiting cap.

[0003] Chinese patent document CN114260292A discloses a waste aluminum recycling device for an easy-open lid production line, relating to the field of easy-open lid production technology. This easy-open lid waste aluminum recycling device includes a housing, inside which a motion mechanism is installed. The motion mechanism includes a motor, the rear end of which is fixedly connected to the housing. The front output shaft of the motor is fixedly connected to a roller. A column is located directly to the left of the motor, the rear end of which is fixedly connected to the housing. The front end of the column is rotatably connected to a roller two via a bearing. Rollers one and two are identical. A moving belt is sleeved on the outer sides of both rollers. The outer surface of the moving belt has six evenly spaced ball-and-cylinder grooves. A clamping mechanism is evenly spaced on the outer side of the moving belt. This easy-open lid waste aluminum recycling device makes subsequent use of waste aluminum sheets more convenient and greatly reduces the sharpness of the edges of the waste aluminum sheets, minimizing the possibility of accidental injury to workers.

[0004] However, in actual use, because the scrap aluminum sheets are small, they need to be recast, which requires transportation. The device needs to transport the bulk scrap aluminum sheets, as it cannot compress them into blocks, making transportation inconvenient. Furthermore, other machinery is needed to handle the scrap aluminum sheets, as they cannot be handled manually. Summary of the Invention

[0005] The main objective of this invention is to provide a waste recycling device for the production of easy-open lids for metal packaging cans, which can effectively solve the problem of inconvenient transportation and handling of waste aluminum sheets.

[0006] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0007] A waste recycling device for the production of easy-open lids of metal packaging cans includes a workbench. The upper end of the workbench is provided with a discharge door. An extrusion molding device is fixed at the lower end of the workbench table. A mounting bracket is fixed together among multiple support legs of the workbench. A recycling component is fixed at the upper end of the mounting bracket.

[0008] The recycling assembly includes a recycling box with an open top. Two guide rods are fixed to the bottom surface of the inner cavity of the workbench. Two sets of mounting brackets are symmetrically fixed to the front end of the recycling box, and there are two mounting brackets in each set. A screw is rotatably mounted between the two mounting brackets in the same set. A drive motor for driving the screw is fixed to the lower end of the recycling box. Two vertical through slots are opened at the front end of the recycling box. A discharge mechanism is provided between the two screws. A through slot adapted to the discharge mechanism is also opened at the front end of the recycling box.

[0009] Preferably, the discharge mechanism includes a fixed rod slidably connected to the recycling bin, and two discharge rods slidably connected to the through groove are fixed at the rear end of the fixed rod. The fixed rod and the two discharge rods together form a discharge fork. Gears are fixed at both ends of the fixed rod. Support rings threaded to the screw are rotatably installed at the ends of the two gears that are far apart from each other. Two mounting brackets are fixed at the front end of the recycling bin, and a rack that matches the gear is fixed at the rear end of the mounting bracket.

[0010] Preferably, the upper ends of the two discharge rods are jointly fixed with a baffle for sealing the through groove.

[0011] Preferably, the top surfaces of the two guide rods are lower than the bottom surface of the second through groove, and the top surfaces of the guide rods are inclined surfaces.

[0012] Preferably, when the first gear meshes with the first rack and the support ring moves upward, the fixing rod rotates counterclockwise; when the first gear meshes with the first rack and the support ring moves downward, the fixing rod rotates clockwise.

[0013] Preferably, the extrusion molding device includes two electric push rods fixedly connected to the worktable. The output ends of the two electric push rods are jointly fixed with a mounting bracket four. Two sets of support frames one are symmetrically fixed on the upper end of the mounting bracket four, and each set of support frames one consists of two. A rotating rod is rotatably connected to the multiple support frames one. Two N-shaped extension rods adapted to the support frames one are fixed on the outer surface of the rotating rod. The ends of the two N-shaped extension rods away from the rotating rod are jointly fixed with a pressure plate adapted to the recycling box. A through groove three adapted to the guide rod is opened on the upper end of the pressure plate. Two sets of limiting components for limiting the N-shaped extension rods are symmetrically provided on the upper end of the mounting bracket four.

[0014] Preferably, the limiting component includes a support frame two fixed to the upper end of the mounting bracket four. A gear two fixedly connected to the rotating rod is rotatably mounted on the end of the support frame two away from the N-shaped extension rod. A rack two adapted to the gear two is fixed on the side of the fixed end of the electric push rod near the N-shaped extension rod. An installation tube is fixed on the end of the support frame two near the N-shaped extension rod. A screw two fixedly connected to the gear two is rotatably mounted in the inner cavity of the installation tube. The screw two and the gear two are driven by a belt. A limiting block slidably connected to the installation tube is threaded on the outer surface of the screw two. A limiting groove adapted to the limiting block is opened at the end of each of the two N-shaped extension rods that are close to each other.

[0015] Preferably, the cross-sectional area of ​​the limiting groove is larger than the cross-sectional area of ​​the limiting block.

[0016] Preferably, when the limiting block is in a horizontal state, the side of the limiting groove away from the pressure plate is in contact with the outer surface of the limiting block.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. This waste recycling device adopts a recycling component design. Through the cooperation between the guide rod and the through groove three, after the waste is compressed into blocks, there are two through grooves on the upper end of the waste blocks. These two through grooves facilitate the handling of the waste blocks by the operator. At the same time, through the cooperation between gear one and rack one, the device can flip the waste blocks. When the operator moves the waste blocks away, they can directly move the waste through the two through grooves without the operator having to flip the waste blocks, which simplifies the operation of the device.

[0019] 2. This invention employs an extrusion molding device design. Through the cooperation between the rotating rod, the N-shaped extension rod, and the limiting component, when the device needs to compress waste into blocks, the pressure plate can rotate to a horizontal state. At the same time, the limiting block limits the N-shaped extension rod, and then the output end of the electric push rod moves downward to compress the waste into blocks. When the device does not need to compress the waste into blocks, the pressure plate can also rotate to a vertical state to prevent the pressure plate from obstructing the recycling bin, thus preventing the waste from falling into the recycling bin and affecting the normal operation of the device.

[0031] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0032] Example 1

[0033] like Figure 1 As shown, a waste recycling device for the production of easy-open can lids in metal packaging includes a workbench 1. The upper end of the workbench 1 is provided with a discharge door 11. Workers can produce easy-open can lids on the workbench 1 and then throw out the waste generated in the production process through the discharge door 11. An extrusion molding device 2 is fixed at the lower end of the workbench 1. Multiple support legs of the workbench 1 are jointly fixed with a mounting bracket 12. A recycling component 3 is fixed at the upper end of the mounting bracket 12.

[0034] like Figure 2 As shown, the recycling component 3 includes a recycling box 31 with an opening at the top. Two guide rods 32 are fixed to the bottom surface of the inner cavity of the workbench 1. Since the waste generated during the production of easy-open lids is also metal, it contains a large amount of metal scraps or thin metal sheets. This waste can easily cut the operator's hands. The design of the two guide rods 32 ensures that after the waste is compressed into blocks, there are two through slots at the top of the waste blocks. These through slots facilitate the operator's handling of the waste blocks. Two sets of mounting brackets 33 are symmetrically fixed at the front end of the collection box 31, and there are two mounting brackets 33 in each set. A screw 34 is rotatably mounted between the two mounting brackets 33 in the same set. A drive motor 35 for driving the screw 34 is fixed at the lower end of the collection box 31. Two vertical through slots 36 are opened at the front end of the collection box 31. A discharge mechanism 37 is provided between the two screws 34. A through slot 38 adapted to the discharge mechanism 37 is also opened at the front end of the collection box 31.

[0035] like Figure 3 - Figure 5 As shown, the discharge mechanism 37 includes a fixed rod 371 that is slidably connected to the recycling box 31. Two discharge rods 372 that are slidably connected to the through groove 36 are fixed at the rear end of the fixed rod 371. The fixed rod 371 and the two discharge rods 372 together form a discharge fork. The discharge fork is used to fork out the waste material after it has been compressed into blocks. Gears 373 are fixed at both ends of the fixed rod 371. Support rings 374 that are threaded to screws 34 are rotatably installed at the ends of the two gears 373 that are far apart from each other. The support rings 374 are threaded to screws 34, so that the fixed rod 371 can move up and down when screws 34 rotate.

[0036] Meanwhile, because the recycling box 31 limits the fixed rod 371, the fixed rod 371 can only move up and down when it comes into contact with the recycling box 31, and cannot rotate. Two mounting brackets 375 are fixed at the front end of the recycling box 31, and a rack 376 that matches the gear 373 is fixed at the rear end of the mounting brackets 375. Due to the setting of the through slot 38, the fixed rod 371 will not come into contact with the recycling box 31 when it moves to the top. At the same time, due to the cooperation between the rack 376 and the gear 373, the fixed rod 371 can rotate counterclockwise, so that the discharge fork can fork out the waste material after it has been compressed into blocks.

[0037] In addition, the upper ends of the two discharge rods 372 are jointly fixed with baffles 377 for sealing the through slots 36. Since the two through slots 36 are designed to pass through, waste material can easily fall out through the through slots 36 when it enters the recycling box 31, thus affecting the normal operation of the device. Therefore, baffles 377 are needed to block the through slots 36. At the same time, when the fixing rod 371 rotates from a horizontal state to a vertical state, the baffles 377 can also support the waste material that has been compressed into blocks. Since the fixing rod 371 rotates relatively slowly, the waste material that has been compressed into blocks will not fall directly, making it convenient for operators to remove the waste material that has been compressed into blocks.

[0038] Furthermore, to facilitate the discharge fork from the compressed waste material when the fixed rod 371 rotates, the top surfaces of the two guide rods 32 are lower than the bottom surface of the through groove 38. At the same time, to prevent waste material from accumulating on the top surface of the guide rods 32, since the waste material can also be long and narrow, it is possible that only half of the waste material is on the top surface of the guide rods 32. When the extrusion molding device 2 compresses the waste material into blocks, the waste material may get stuck on the outer surface of the guide rods 32 and the contact part between the extrusion molding device 2 and the guide rods 32, thus affecting the normal operation of the device. Therefore, the top surface of the guide rods 32 is an inclined surface.

[0039] Furthermore, to facilitate the ejection of the compressed blocks by the discharge fork, and also to facilitate the removal of waste blocks by the operator, such as... Figure 9 As shown, when gear 373 meshes with rack 376 and support ring 374 moves upward, fixing rod 371 rotates counterclockwise, causing the two discharge rods 372 to rotate from a horizontal to a vertical position. This allows the through-slot of the waste block to rotate from a vertical to a horizontal position. Since there are no rear components obstructing the through-slot, the operator can use the two rods or fork-shaped rods to remove the waste block. Figure 10 As shown, when gear 373 meshes with rack 376 and support ring 374 moves downward, fixing rod 371 rotates clockwise, which allows the two discharge rods 372 to rotate from a vertical state to a horizontal state. Then the discharge fork moves horizontally downward, facilitating the reuse of the device.

[0040] The specific implementation of this embodiment is as follows: During use, the easy-open cover is processed on the workbench 1, and the resulting waste material falls into the recycling bin 31 through the discharge door 11. Once the recycling bin 31 is full, the extrusion molding device 2 is controlled to compress the waste material into blocks. At this time, the discharge door 11 needs to be closed to prevent waste material from continuing to fall through the discharge door 11 while the extrusion molding device 2 is compressing the waste into blocks, thus affecting the normal operation of the device. After the waste material blocks are formed, the drive motor is controlled... 35 allows the support ring 374 to move upward, further enabling the discharge rod 372 to drag the waste block upward. Then, when gear 373 meshes with rack 376, the recycling box 31 will rotate, causing the discharge rod 372 to rotate from a horizontal state to a vertical state. Due to the design of the baffle 377 and the discharge rod 372 working together, the through slot of the waste block can rotate from a vertical state to a horizontal state. Since there are no parts at the rear to block the through slot, the operator can use two rods or a fork rod to remove the waste block.

[0041] Then, the drive motor 35 is controlled to move the support ring 374 downward. At the same time, due to the cooperation between the gear 373 and the rack 376, the discharge rod 372 rotates from a vertical state to a horizontal state. Then the discharge rod 372 returns to the bottom of the recycling box 31. By opening the discharge door 11, the waste can fall back into the recycling box 31, which is convenient for the next operation of the device.

[0042] Example 2

[0043] This embodiment is a further improvement on the extrusion molding device 2 based on the first embodiment, so that the device can compress waste material into blocks during use.

[0044] like Figure 5As shown, the extrusion molding device 2 includes two electric push rods 21 fixedly connected to the worktable 1. The output ends of the two electric push rods 21 are jointly fixed with a mounting bracket 22. Two sets of support frames 23 are symmetrically fixed on the upper end of the mounting bracket 22, and there are two support frames 23 in each set. The multiple support frames 23 are rotatably connected to a rotating rod 24. Two N-shaped extension rods 25 adapted to the support frames 23 are fixed on the outer surface of the rotating rod 24. The two sets of support frames 23 are used to limit the N-shaped extension rods 25 so that the N-shaped extension rods 25 cannot slide back and forth when the rotating rod 24 is rotating. The ends of the two N-shaped extension rods 25 away from the rotating rod 24 are jointly fixed with a pressure plate 26 adapted to the recycling box 31.

[0045] Meanwhile, the N-shaped extension rod 25 adopts an N-shaped design because when the discharge door 11 is opened, the pressure plate 26 cannot block the recycling box 31 to prevent waste from falling onto the pressure plate 26 and affecting the normal operation of the device. The upper end of the pressure plate 26 is provided with a through groove 3 27 that matches the guide rod 32. The through groove 3 27, through its cooperation with the guide rod 32, allows the pressure plate 26 to press the waste into blocks, with two through grooves at the upper end of the waste block, which facilitates the handling of the waste block by the operator. The upper end of the mounting bracket 4 22 is symmetrically provided with two sets of limiting components 28 for limiting the N-shaped extension rod 25.

[0046] Furthermore, to ensure that the pressure plate 26 is horizontal when the mounting bracket 4 22 moves downwards, facilitating the pressing of the waste block, and also to ensure that the pressure plate 26 is vertical when the discharge door 11 is opened, preventing the pressure plate 26 from obstructing the discharge door 11 and thus preventing the waste from falling into the recycling box 31, such as... Figure 7 and Figure 8 As shown, the limiting component 28 includes a support frame 281 fixed to the upper end of the mounting bracket 22. A gear 282 fixedly connected to the rotating rod 24 is rotatably mounted on the end of the support frame 281 away from the N-shaped extension rod 25. A rack 283 adapted to the gear 282 is fixed on the side of the fixed end of the electric push rod 21 near the N-shaped extension rod 25. The rack 283 and the gear 282 cooperate with each other, so that when the output end of the electric push rod 21 is extended or retracted, the rotating rod 24 can rotate, further enabling the pressure plate 26 to rotate around the rotating rod 24 as the central axis. An installation tube 284 is fixed on the end of the support frame 281 near the N-shaped extension rod 25. A screw 285 fixedly connected to the gear 282 is rotatably mounted inside the installation tube 284.

[0047] In addition, the screw 285 and gear 282 are driven by a belt, which further enables the screw 285 to rotate when the gear 282 rotates. A limiting block 286 is threadedly installed on the outer surface of the screw 285 and slidably connected to the mounting tube 284. The limiting block 286 is threadedly installed with the screw 285, so that the limiting block 286 can move closer to the N-shaped extension rod 25 when the screw 285 rotates. The ends of the two N-shaped extension rods 25 that are close to each other are provided with limiting grooves 287 that are adapted to the limiting block 286. When the output end of the limiting block 286 is located in the limiting groove 287, the limiting block 286 can limit the N-shaped extension rod 25 to prevent the N-shaped extension rod 25 from rotating during use, thereby affecting the pressing plate 26 to press and form the waste material.

[0048] like Figure 8 As shown, the cross-sectional area of ​​the limiting groove 287 is larger than that of the limiting block 286, allowing the limiting block 286 to be inserted into the limiting groove 287. At the same time, since the pressure plate 26 exerts an upward force on the pressure plate 26 when it is pressing the waste material, when the limiting block 286 is in a horizontal state, the side of the limiting groove 287 away from the pressure plate 26 contacts the outer surface of the limiting block 286, which allows the limiting block 286 to limit the N-shaped extension rod 25, so that the pressure plate 26 can remain horizontal.

[0049] The specific implementation of this embodiment is as follows: When the electric push rod 21 is in the retracted state, the pressure plate 26 is in the vertical state. When the output end of the electric push rod 21 extends, due to the mutual cooperation between the gear 282 and the rack 283, the N-shaped extension rod 25 can rotate around the rotating rod 24 as the central axis, further rotating from the vertical state to the horizontal state. At the same time, through the mutual cooperation between the screw 285 and the limiting block 286, the limiting block 286 is inserted into the limiting groove 287, further limiting the N-shaped extension rod 25, so that the pressure plate 26 can press the waste into blocks.

[0050] It should be noted that the specific installation method, circuit connection method and control method of the electric actuator 21 and the drive motor 35 in this invention are all conventional designs, and will not be described in detail in this invention.

[0051] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention.
