Description

Technical Field

[0001] This utility model relates to the field of cardboard box processing technology, and in particular to a hole-opening device for processing stone paper cardboard boxes. Background Technology

[0002] Stone paper boxes, as an environmentally friendly packaging material, are widely used in the packaging of food, medicine and precision electronic products because their main components are calcium carbonate and polymer resin, which have advantages such as waterproofness, tear resistance and biodegradability.

[0003] Stone paper boxes, like other types of boxes, require perforations for ventilation or gripping. Traditional perforation processes involve manual handling of the boxes to the perforation device, positioning, clamping, and perforation, resulting in low efficiency and hindering production. Furthermore, unlike other materials, the stone paperboard itself generates a large amount of ultrafine powder during perforation, which is dispersed into the work environment and can be easily inhaled, potentially harming the health of operators.

[0004] Therefore, it is necessary to provide a fully automated, dust-free hole-opening device for processing stone paper cartons. Utility Model Content

[0005] To address the efficiency requirements of perforation in stone paper boxes and the technical problem of dust easily being dispersed into the air during perforation, this utility model provides a perforation device for processing stone paper boxes, which improves perforation efficiency and safety.

[0006] A hole-opening device for processing stone paper cartons includes a frame, on which a conveying assembly is mounted, and a dust collection hood is fitted over the conveying assembly. A negative pressure fan and several dust collection pipes communicating with the interior of the dust collection hood are mounted on the top of the dust collection hood. An exhaust pipe is mounted on the air inlet of the negative pressure fan, and the dust collection pipes are connected to the exhaust pipes. The air outlet of the negative pressure fan is connected to a dust collection box. The dust collection hood has an inlet and an outlet at both ends along the conveying direction. The conveying assembly includes a first conveyor belt, a hole-opening mechanism, and a second conveyor belt arranged sequentially along the conveying direction. The hole-opening mechanism includes an operating platform, on which several transmission rollers are equidistantly embedded on the top surface. The transmission rollers are rotatable along the conveying direction, and adjacent transmission rollers form a platform. The conveying surfaces of the first conveyor belt, the transmission rollers, the platform, and the second conveyor belt are all on the same horizontal plane. A fixed frame is provided directly above each platform, and the fixed frame is fixedly connected to the operating table. Several sliding rods are arranged parallel to the transmission rollers on the fixed frame, and several fixed seats are slidably connected to the sliding rods. Each fixed seat is connected to a mounting base via a lifting assembly. A perforating cutter is fixedly installed on the mounting base, and the lifting assembly is used to drive the mounting base to rise and fall, thereby causing the perforating cutter to move closer to or away from the platform. A strip-shaped through hole is provided on the platform, located below the perforating cutter. A collection box is provided below the operating table, and the strip-shaped through hole communicates with the collection box.

[0007] Furthermore, the lifting assembly includes a lifting cylinder, a piston rod, and a lifting seat mounted on the fixed base. The lifting cylinder is connected to the lifting seat via the piston rod, and the mounting base is disposed on the lifting seat.

[0008] Furthermore, the mounting base is also provided with two lower pressure plates, which are located on both sides of the drilling knife. Each lower pressure plate is fixedly connected to the mounting base through a first telescopic rod. The first telescopic rod is fitted with a first spring, and the two ends of the first spring abut against the bottom surface of the mounting base and the top surface of the lower pressure plate, respectively.

[0009] Furthermore, the punching tool is a cylindrical annular tool, and a second telescopic rod is fixedly connected to the top of the inner cavity of the cylindrical annular tool. A push block is fixedly connected to the lower end of the second telescopic rod. A second spring is sleeved on the second telescopic rod, and the two ends of the second spring abut against the top of the inner cavity of the cylindrical annular tool and the top surface of the push block, respectively.

[0010] Furthermore, the operating platform is provided with mounting plates at both ends along the conveying direction. Each mounting plate has a limiting baffle parallel to the mounting plate on its inner side. Each mounting plate is threaded with a threaded rod, and one end of the threaded rod is provided with a turntable, while the other end is connected to the corresponding limiting baffle. Each end of the threaded rod is provided with a limiting rod, which passes through the mounting plate and is connected to the corresponding limiting baffle.

[0011] Furthermore, the transmission roller component includes two transmission rollers arranged in sequence, and the transmission rollers are rotatably arranged along the conveying direction, and one end of the transmission rollers is connected to a driving mechanism.

[0012] Furthermore, the dust collection hood is equipped with several horn-shaped dust collection heads, and each horn-shaped dust collection head is connected to a corresponding dust collection tube.

[0013] Furthermore, the dust cover is provided with a transparent observation window.

[0014] Furthermore, a dust sensor for detecting the dust concentration inside the dust collection hood is provided on the inner side of both the inlet and outlet ends of the dust collection hood.

[0015] The beneficial effects of this utility model are as follows: This utility model provides a hole-opening device for processing stone paper cartons. A first conveyor belt, a hole-opening mechanism, and a second conveyor belt are sequentially arranged along the conveying direction. The stone paperboard forming the cartons is conveyed from the first conveyor belt to the hole-opening mechanism for hole opening, and then discharged via the second conveyor belt. This achieves fully automated feeding, hole-opening, and unloading of the stone paperboard, thereby improving the hole-opening efficiency and economic benefits during stone paper carton processing. Simultaneously, by installing a dust suction hood around the output component, dust generated during hole opening is prevented from drifting into the working environment and being inhaled, thus protecting the health of operators. Furthermore, a negative pressure fan, through an exhaust pipe and a dust suction pipe, promptly absorbs dust emitted from inside the dust suction hood, preventing excessive dust from overflowing outside the hood or accumulating on the conveying component and causing blockage or damage. This further ensures the safety and efficiency of the device and extends its service life. In addition, by setting a strip-shaped through hole below the drilling tool, the waste generated during drilling can fall into the collection box through the strip-shaped through hole, thus preventing the waste from affecting the normal drilling process.

Detailed Implementation

[0024] To provide a more detailed description of this utility model, the following description is provided in conjunction with the accompanying drawings. It should be noted that the embodiments described below are merely some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0025] refer to Figure 1 As shown, a hole-opening device for processing stone paper boxes is mainly used for opening holes in stone paperboard, and can also be used for opening holes in folded or three-dimensional stone paper boxes. It includes a frame 1, on which a conveying component is provided, and a dust suction hood 2 is provided on the conveying component.

[0026] Specifically, refer to Figure 1 and Figure 2 As shown, the top of the dust collection hood 2 is equipped with a negative pressure fan 3 and several dust collection pipes 4 that communicate with the inside of the dust collection hood 2. The air inlet of the negative pressure fan 3 is equipped with an exhaust pipe 5, and the dust collection pipes 4 are connected to the exhaust pipe 5. The air outlet of the negative pressure fan 3 is connected to a dust collection box.

[0027] By installing a dust hood 2 around the output component, dust generated during opening is prevented from drifting into the working environment and being inhaled by the operator, thus avoiding harm to their health. At the same time, a negative pressure fan 3 is installed to promptly absorb the dust emitted from inside the dust hood 2 through the exhaust pipe 5 and the dust suction pipe 4, preventing excessive dust from overflowing outside the dust hood 3 or accumulating on the conveying component and causing blockage or damage. This further ensures the safety and efficiency of the device and extends its service life.

[0028] In some embodiments, the dust collection hood 2 is provided with a plurality of trumpet-shaped dust collection heads 401, which are connected one-to-one with the dust collection pipe 4. By setting the trumpet-shaped dust collection heads 401, a wider dust collection range can be covered, dust escape can be reduced, and dust collection efficiency can be improved.

[0029] The dust collection hood 2 is provided with an inlet and an outlet at both ends along the conveying direction; the conveying assembly includes a first conveyor belt 6, an opening mechanism 7 and a second conveyor belt 8 arranged sequentially along the conveying direction.

[0030] Among them, reference Figure 3 , Figure 4 as well as Figure 6 As shown, the opening mechanism 7 includes an operating table 71. A plurality of transmission rollers 72 are equidistantly embedded on the top surface of the operating table 71. The transmission rollers 72 are rotatably arranged along the conveying direction, and a platform 73 is formed between adjacent transmission rollers 72. In this embodiment, the transmission roller 72 includes two transmission rollers 721 arranged sequentially, and the transmission rollers 721 are rotatably arranged along the conveying direction. One end of each transmission roller 721 is connected to a driving mechanism.

[0031] The conveying surfaces of the first conveyor belt 6, the transmission roller 72, the platform 73, and the second conveyor belt 8 are all on the same horizontal plane. This allows the stone paperboard that makes up the carton to be placed on the conveying surface of the first conveyor belt 6, conveyed from the first conveyor belt 6 to the punching mechanism 7 for punching, transferred through the transmission roller 72 to the conveying surface of the second conveyor belt 8, and then sent out through the second conveyor belt 8. This achieves fully automated feeding, punching, and unloading of the stone paperboard, thereby improving the punching efficiency and economic benefits during the processing of stone paper cartons.

[0032] In this embodiment, the position of the stone paperboard to be perforated can be controlled by presetting the interval operation time of the first conveyor belt 6, the perforation mechanism 7 and the second conveyor belt 8 after feeding, so that it stops conveying and perforating when it reaches the preset perforation position. Alternatively, a detection device can be set to detect the position of the stone paperboard to be perforated and control the start and stop of the conveying. This is conventional technology in the field and will not be described in detail here.

[0033] A mounting bracket 74 is provided directly above each of the platform 73. The mounting bracket 74 is fixedly connected to the operating table 71, and the mounting bracket 74 is provided with several slide rods 75 arranged parallel to the transmission rollers 72. Several fixed seats 76 are slidably connected to the slide rods 75, and each fixed seat 76 is connected to a mounting base 10 through a lifting assembly 9. In actual use, the position of the mounting base 10 on the slide rod 75 can be adjusted according to the opening requirements.

[0034] A hole-making cutter 11 is fixedly mounted on the mounting base 10. The lifting assembly 9 is used to drive the mounting base 10 to rise and fall, thereby causing the hole-making cutter 11 to move closer to or away from the table surface 73 to perform hole-making operations on the stone paperboard on the table surface 73. In actual use, different types of hole-making cutters 11 can be replaced according to the hole-making requirements.

[0035] The tabletop 73 has a strip-shaped through hole 77 located below the drilling knife 11; a collection box 12 is provided below the operating table 71, and the strip-shaped through hole 77 is connected to the collection box 12.

[0036] By setting a strip-shaped through hole 77 below the punching knife 11, the cardboard waste generated during punching can fall into the collection box 12 through the strip-shaped through hole 77, thus preventing the waste from affecting the normal punching process.

[0037] The lifting assembly 9 includes a lifting cylinder 91, a piston rod 92, and a lifting seat 93 mounted on the fixed base 76. The lifting cylinder 91 is connected to the lifting seat 93 via the piston rod 92, and the mounting base 10 is disposed on the lifting seat 93. The lifting cylinder 91 drives the piston rod 92 to extend and retract, thereby driving the lifting seat 93 to rise and fall, so that the mounting base 10 drives the drilling knife 11 to rise and fall to complete the drilling of the stone paperboard that reaches the table surface 73.

[0038] The mounting base 10 is also provided with two lower pressure plates 13, which are located on both sides of the hole punch 11. Each lower pressure plate 13 is fixedly connected to the mounting base 10 through a first telescopic rod 14. The first telescopic rod 14 is fitted with a first spring 15, and the two ends of the first spring 15 abut against the bottom surface of the mounting base 10 and the top surface of the lower pressure plate 13, respectively.

[0039] As the mounting base 10 drives the drilling knife 11 to rise and fall, the lower pressure plate 13 rises and falls synchronously, contacting the stone paperboard with the blade of the drilling knife 11. At this time, the lower pressure plate 13 presses down on the stone paperboard on both sides of the drilling knife 11, fixing the position of the stone paperboard and ensuring the accuracy of the drilling. Subsequently, the drilling knife 11 continues to press down to drill a hole in the stone paperboard. At this time, while the lower pressure plate 13 presses down on the stone paperboard, the first telescopic rod 14 and the first spring 15 are compressed, pressing the stone paperboard to facilitate the drilling knife 11 to drill the hole. After the drilling is completed, the drilling knife 11 rises, and the first telescopic rod 14 and the first spring 15 are compressed to return to their original state.

[0040] In some embodiments, the punching knife 11 is a cylindrical annular knife, and a second telescopic rod 16 is fixedly connected to the top of the inner cavity of the cylindrical annular knife. A push block 17 is fixedly connected to the lower end of the second telescopic rod 16. A second spring 18 is sleeved on the second telescopic rod 16, and the two ends of the second spring 18 abut against the top of the inner cavity of the cylindrical annular knife and the top surface of the push block 17, respectively.

[0041] The cylindrical ring cutter moves downwards and quickly passes through the stone paperboard to complete the opening. Before the blade of the cylindrical ring cutter contacts the stone paperboard, the push block 17 inside the cylindrical ring cutter abuts against the stone paperboard. When the cylindrical ring cutter moves downwards, the push block 17 will move inwards due to the obstruction of the stone paperboard, squeezing the connection between the second telescopic rod 16 and the second spring 18. After the cylindrical ring cutter completes the opening, the elasticity of the second spring 18 drives the push block 17 to move downwards, automatically pushing the cardboard waste remaining in the inner cavity of the cylindrical ring cutter out of the inner cavity and falling into the collection box 12 through the strip-shaped through hole 73 for unified collection. This avoids the preparation waste remaining in the inner cavity of the cylindrical ring cutter after the opening, which would cause blockage and affect the accuracy and quality of the opening.

[0042] refer to Figure 1 and Figure 5 As shown, in some embodiments, the operating table 71 is provided with mounting plates 19 at both ends along the conveying direction. The inner side of each mounting plate 19 is provided with a limiting baffle 20 arranged parallel to the mounting plate 19. Each mounting plate 19 is threaded with a threaded rod 21, and one end of the threaded rod 21 is provided with a turntable 22, and the other end is connected to the corresponding limiting baffle 20. Each end of the threaded rod 21 is provided with a limiting rod 23, which passes through the mounting plate 19 and is connected to the corresponding limiting baffle 20.

[0043] A limiting channel is formed between the two limiting baffles 20, allowing the stone paperboard to pass through the limiting channel at a preset position, thereby improving the accuracy of the opening; by rotating the turntable 22, the limiting baffles 20 are moved inward, thereby adjusting the width of the limiting channel to accommodate stone paperboards of different sizes.

[0044] In some embodiments, the dust hood 2 is provided with a transparent observation window 24, which allows the user to observe whether the conveying and opening of the stone paperboard inside the dust hood 2 is proceeding normally, and facilitates timely detection of faults.

[0045] In some embodiments, a dust sensor (not shown in the figure) is provided on the inner side of both the feed end and the discharge end of the dust hood 2 for detecting the dust concentration inside the dust hood 2, so as to monitor the dust concentration inside the dust hood 2 in real time, thereby enabling the negative pressure fan 3 to be turned on or off or the power of the negative pressure fan 3 to be adjusted according to the dust concentration.

[0046] The preferred embodiments of this utility model disclosed above are merely illustrative of the present utility model and do not limit the utility model to the specific implementations described. Obviously, other modifications and variations can be made based on the content of this specification. The embodiments selected and specifically described in this specification are intended to better explain the principles and practical applications of this utility model, thereby enabling those skilled in the art to better understand and utilize it. They are not intended to limit the utility model, and any simple modifications to this utility model fall within the protection scope of this utility model.
