Description

Technical Field

[0001] This utility model relates to the field of plastic bucket handle manufacturing technology, and in particular to a punching device for assembly holes in plastic bucket handles. Background Technology

[0002] In the manufacturing and processing of plastic products, plastic buckets are a common storage and transportation container, and the assembly quality of their handles directly affects the product's ease of use and safety. In particular, during the assembly process of plastic bucket handles, the cleanliness of the assembly holes is a key factor in ensuring a secure connection of the handle.

[0003] Traditional plastic bucket handle assembly hole punching devices usually only focus on the punching action itself, while ignoring the impact of impurities such as burrs and debris generated during the punching process on the assembly quality. These impurities not only reduce the usability of the assembly hole, but also scratch the operator's hands during use, posing a safety hazard. After the assembly hole is processed, the handle with the punched assembly hole needs to be cleaned, that is, the inside of the handle, to remove residual plastic debris and oil stains. Currently, most businesses still rely primarily on manual labor for cleaning. Common methods include brushing or compressed air blowing. When using brushes, the hardness and shape of the brushes make it difficult to remove sticky impurities adhering to the inside of the handle. Furthermore, during manual cleaning, it's difficult to maintain consistent brush pressure and direction, resulting in some areas remaining uncleaned and impurities still present. While compressed air blowing can generate some airflow to remove some impurities, it's often insufficient to completely remove stubborn oil stains and fine debris, causing inconvenience in practical use.

[0004] Therefore, it is necessary to provide a new punching device for the mounting hole of plastic bucket handles to solve the above-mentioned technical problems. Utility Model Content

[0013] Compared with related technologies, the punching device for the assembly hole of the plastic bucket handle provided by this utility model has the following advantages: In the cleaning mechanism of this device, multiple cleaning rollers are arranged in a relatively rotatable manner on the inner wall of the connector and are in contact with the inner wall of the plastic bucket handle.

Compared with traditional manual brush cleaning, this rotational wiping method can better cover all parts of the inside of the handle. Moreover, when the drive component rotates back and forth and drives the connector to swing, the cleaning rollers are subjected to lateral squeezing force, which further enhances the cleaning force and can deeply remove those highly adhesive oil stains and fine debris, achieving a more thorough cleaning. This ensures that there are fewer impurities remaining on the inside of the handle after the assembly hole has been drilled, which to a certain extent provides a guarantee for the subsequent stable connection of the handle. This solves the problem that existing devices have difficulty cleaning the inside of the handle after the assembly hole has been drilled. This device eliminates the need for tedious manual brushing and frequent compressed air blowing. The drive assembly automatically rotates the connecting parts and cleaning rollers to clean the inside of the handle after drilling, reducing manual intervention and saving significant manpower and time costs. In mass production of plastic buckets, it significantly shortens the processing cycle for each handle, improving overall production efficiency and meeting the needs of large-scale production. Cleaning without close contact with the handle effectively reduces contact with potential hazards, lowering the probability of workplace accidents and providing a safer working environment for operators.

[0016] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0017] Please refer to the following: Figures 1 to 8 ,in, Figure 1 A schematic diagram of the overall structure of the punching device for the plastic bucket handle assembly hole provided by this utility model; Figure 2 for Figure 1 Enlarged view of point A in the middle; Figure 3 A front view structural schematic diagram of the punching device for the assembly hole of the plastic bucket handle provided by this utility model; Figure 4 This is a schematic diagram of the punching mechanism; Figure 5 for Figure 4 Enlarged view of point B in the middle; Figure 6 This is a schematic diagram of the cleaning mechanism; Figure 7 This is a schematic diagram of the structure of a ring-shaped turntable; Figure 8 for Figure 7 Enlarged view of point C in the middle; Figure 9 This is a schematic diagram of the handle structure after drilling.

[0018] In some embodiments, such as Figures 1 to 9As shown, a punching mechanism is installed on the top of the fixed frame 1. The fixed frame 1 is characterized by a cleaning mechanism for rinsing the plastic bucket handle. The cleaning mechanism includes a drive assembly, a connector located at the bottom of the drive assembly, and a plurality of cleaning rollers 76. The drive assembly drives the connector to rotate. The plurality of cleaning rollers 76 are relatively rotatably disposed on the inner side wall of the connector. The plurality of cleaning rollers 76 are respectively in contact with the inner side wall of the plastic bucket handle. The inner side of the connector is also provided with a rotating assembly for rotating the plurality of cleaning rollers 76. The inner side of the plurality of cleaning rollers 76 is in contact with the inner side of the plastic bucket handle. When the drive assembly swings back and forth, the drive assembly drives the connector to swing, which causes the cleaning roller 76 to be subjected to lateral extrusion force, and the cleaning roller 76 is in a further cleaning state. For reference Figure 9 As shown, the handle before the hole is U-shaped, and the handle after the hole has a U-shaped groove on its inner side. The U-shaped groove is the inner side of the handle and the assembly hole, which is used for subsequent installation on the plastic bucket. The U-shaped groove is the place where the handle is manually twisted. The cleaning roller 76 is preferably made of a flexible material, such as a sponge. Sponges are soft and porous, and have good water and dirt absorption capabilities. When cleaning the inside of the plastic bucket handle, they can not only wipe away surface impurities, but also absorb some oil and moisture, making the cleaning more thorough.

[0019] Before cleaning the handle, it can be manually or mechanically moved into the designated location for cleaning.

[0020] Specifically, multiple cleaning rollers 76 are rotatably arranged on the inner wall of the connector and are in contact with the inner wall of the plastic bucket handle. When the drive component drives the connector to rotate, the cleaning rollers 76 are flexible and rotate synchronously, which can perform rotational wiping on the inside of the handle. Compared with traditional manual brush cleaning, this rotational wiping method can better cover all parts of the inside of the handle. Moreover, when the drive component rotates back and forth and drives the connector to swing, the cleaning rollers 76 are subjected to lateral squeezing force, which further enhances the cleaning power and can deeply remove those highly adhesive oil stains and fine debris, achieving a more thorough cleaning and ensuring that there are fewer impurities remaining on the inside of the handle after the conversion hole is drilled. To a certain extent, this provides a guarantee for the subsequent stable connection of the handle. Furthermore, this device eliminates the need for tedious manual brushing and frequent compressed air blowing. The drive assembly automatically rotates the connecting parts and cleaning roller 76 to clean the inside of the handle after drilling, reducing manual intervention and saving significant manpower and time costs. In mass production of plastic buckets, it can significantly shorten the processing cycle of each handle, improve overall production efficiency, and meet the needs of large-scale production. Cleaning without close contact with the handle effectively reduces contact with potential hazards, lowers the probability of workplace accidents, and provides a safer working environment for operators.

[0021] In some embodiments, reference is made to Figure 1 , Figure 2 , Figure 3 , Figure 6 , Figure 7 , Figure 8 as well as Figure 9 As shown, the drive assembly includes a second mounting bracket 4 and a first motor 42. A third mounting bracket 41 is fixed to the top of the second mounting bracket 4. The fixed end of the first motor 42 is fixed to the bottom of the third mounting bracket 41. A first through groove 421 is opened on the surface of the third mounting bracket 41. An annular turntable 422 is rotatably arranged in the first through groove 421. The output end of the first motor 42 is fixedly connected to the top of the annular turntable 422. A cleaning seat 423 is rotatably arranged at the bottom of the annular turntable 422. A connecting piece is fixed to the bottom of the cleaning seat 423. The connector includes a first fixed base 424, a pressure block 425 for fixing the handle of the plastic bucket is fixed at the bottom of the first fixed base 424, a second motor 7 is fixed at the top wall of the first fixed base 424, a coupling 71 is fixed at the output end of the second motor 7, a rotating rod 72 is fixed at the other end of the coupling 71, the bottom of the rotating rod 72 rotates on the bottom wall of the first fixed base 424, a plurality of rotating columns 74 are also provided inside the first fixed base 424, the two ends of the plurality of rotating columns 74 rotate on the top wall and the bottom wall of the first fixed base 424 respectively, a first gear 73 is fixed on the surface of the rotating rod 72, a second gear 75 is fixed on the surface of the plurality of rotating columns 74, the first gear 73 and the plurality of second gears 75 are at the same horizontal height, the plurality of second gears 75 mesh with each other, and one of the second gears 75 meshes with the first gear 73, the bottom of the rotating rod 72 and the plurality of rotating columns 74 all pass through the bottom of the first fixed base 424 and are fixedly connected to the top of the plurality of cleaning rollers 76 respectively; The top of the second mounting frame 4 is fixed with multiple second cylinders 43, and the bottom of the multiple cleaning rollers 76 is provided with a second pressure plate 44. One side of the second pressure plate 44 slides on the inner side wall of the second mounting frame 4. One end of the multiple second cylinders 43 passes through the top of the second mounting frame 4 and is fixedly connected to the top of the second pressure plate 44. The top of the second pressure plate 44 is fixed with two second locking blocks 6. The two second locking blocks 6 are located directly below the first fixing seat 424. A fixing block 62 is provided between the two second locking blocks 6. The fixing block 62 is fixed to the top of the first fixing seat 424. A placement seat 63 is fixed to the top of the fixing block 62. A through hole 632 is provided through the top of the placement seat 63. The through hole 632 is used for the falling of debris. A placement groove 631 is provided on the inner side wall of the through hole 632. The plastic bucket handle is placed on the two placement grooves 631. The pressure block 425 is located directly below the two placement grooves 631. An anti-slip layer 61 is fixed on the side of the two second locking blocks 6 near the placement seat 63. The anti-slip layer 61 is in contact with the outer side of the placement seat 63. Specifically, during use, the plastic bucket handle is placed on the placement slot 631 of the placement seat 63. The second cylinder 43 operates, pulling the second pressure plate 44 upward. The two second clamping blocks 6 clamp the placement seat 63 through the anti-slip layer 61. At the same time, the pressure block 425 presses against the top of the plastic bucket handle, fixing it firmly. At this time, the second motor 7 starts, driving the rotating rod 72 to rotate through the coupling 71. The first gear 73 on the rotating rod 72 rotates accordingly. Since the first gear 73 meshes with one of the second gears 75, and multiple second gears 75 mesh with each other, multiple second gears 75 will also rotate, thereby driving multiple rotating columns 74 to rotate, and finally causing multiple cleaning rollers 76 to rotate, performing preliminary cleaning on the inside of the plastic bucket handle. When further cleaning is required, the first motor 42 starts, driving the annular turntable 422 to swing left and right. The annular turntable 422 drives the cleaning seat 423 to swing left and right, thereby causing the connecting parts and cleaning roller 76 to swing. During the swinging process, the cleaning roller 76 is subjected to lateral squeezing force, which further cleans the inside of the plastic bucket handle. To a certain extent, it can remove residual burrs, hard debris and oil stains and other impurities.

[0022] In some embodiments, reference is made to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 as well as Figure 9As shown, the punching mechanism includes a first mounting frame 3 and an electric cylinder 31. The first mounting frame 3 is located on one side of the second mounting frame 4. The electric cylinder 31 is fixed to the top of the mounting frame 1. The output end of the electric cylinder 31 passes through the top of the first mounting frame 3 and is fixed to a mounting base 33. A punch 34 for cutting plastic bucket handles is fixed to the bottom of the mounting base 33. A first pressure plate 35 is slidably arranged on the inner side wall of the mounting frame 1. A plurality of first cylinders 32 are also fixed to the top of the mounting frame 1. The output ends of the plurality of first cylinders 32 pass through the top of the first mounting frame 3 and are fixedly connected to the top of the first pressure plate 35. Two first locking blocks 341 are fixed to the top of the plate 35. Anti-slip layer 342 is fixed on the inner side wall of each of the two first locking blocks 341. A cutting seat 343 is provided between the two first locking blocks 341. The cutting seat 343 is located directly below the mounting seat 33. The cutting seat 343 is fixed to the top of the first pressure plate 35. The plastic bucket handle is snapped into the top of the cutting seat 343. The anti-slip layer 342 is in contact with the outer side of the plastic bucket handle. A cutting groove 344 is also provided through the top of the cutting seat 343. The cutting groove 344 is located directly below the punch 34, and the size of the punch 34 matches that of the cutting groove 344. Among them, punch 34 is used to cut the handle of the plastic bucket to form a U-shaped groove-type assembly hole on its surface; A buffer assembly is also provided between the first mounting bracket 3, the second mounting bracket 4 and the fixed bracket 1; The buffer assembly includes two base plates 5, which are located between the first mounting bracket 3 and the second mounting bracket 4. One side of each base plate 5 is fixed to the inner sidewall of the first mounting bracket 3 and the second mounting bracket 4 respectively by bolts 53. Each base plate 5 has a base plate 52 below it. The base plates 5 and 5 are connected by multiple telescopic rods 51, and springs 511 are fitted on the surface of each telescopic rod 51. A fixing plate 11 is fixed to the top of the fixing frame 1, and a collection box 12 is fixed to the top of the fixing plate 11. The collection box 12 is located below the fixing frame 1 and the second mounting frame 4. The top of the collection box 12 is provided with a first collection chamber 121 and a second collection chamber 122. The first collection chamber 121 and the second collection chamber 122 are located directly below the fixing frame 1 and the second mounting frame 4, respectively. A material leakage trough is provided through the bottom of the first collection chamber 121 and the second collection chamber 122. A filter plate 123 for filtering debris is fixed on the inner side wall of the material leakage trough. Two collection boxes 2 for collecting debris are fixed inside the fixing frame 1. The collection boxes 2 are located directly below the first collection chamber 121 and the second collection chamber 122, respectively. The surface of the collection boxes 2 is provided with a discharge port 21.

[0023] Specifically, during use, the plastic bucket handle is snapped onto the top of the cutting seat 343. At this time, the anti-slip layer 342 is in contact with the outside of the handle, which plays a preliminary role in fixing and preventing slippage. The electric cylinder 31 is activated, and its output end drives the mounting seat 33 and the punch 34 to move downward. At the same time, multiple first cylinders 32 work to push the first pressure plate 35 to move downward, so that the first locking block 341 further presses the plastic bucket handle. To a certain extent, this can ensure that the handle is stable in position during the punching process and does not shake. At this time, the punch 34 continues to move downward, passes through the plastic bucket handle and enters the cutting groove 344 to complete the punching of the assembly hole. During the punching process, the debris falls into the first collection chamber 121 and some of it enters the second collection chamber 122 through the through hole 632. After being filtered by the mesh on the surface of the filter plate 123, the fine debris falls into the collection box 2 below through the material leakage chute. The debris in the collection box 2 is cleaned periodically through the discharge port 21. Furthermore, during the operation of the device, the impact force generated during drilling will cause the first mounting bracket 3 and the second mounting bracket 4 to vibrate. At this time, the buffer assembly plays a role. The telescopic rod 51 between the base plate 1 5 and the base plate 2 52 extends and retracts, and the spring 511 is compressed or stretched to absorb and disperse the impact force, reduce the impact of vibration on the device, and the telescopic rod 51 has sliding friction between them. The sliding friction force is less than the elastic force of the spring 511, which allows it to be buffered and reset, and has a certain buffering effect to prevent the pressure plate from loosening and falling off, which would cause damage to the device.
