Description

Technical Field

[0001] This invention relates to the field of cardboard box die-cutting waste treatment technology, and in particular to a cardboard box die-cutting waste adsorption and transportation device and its heat treatment method. Background Technology

[0002] Cardboard boxes, as a packaging material with high structural strength, excellent cushioning performance, and environmental friendliness and recyclability, have been widely used in the transportation packaging of e-commerce logistics, food and beverages, electronic products, and industrial goods. In the production process of cardboard boxes, the die-cutting process is a key step in punching and creasing the printed corrugated cardboard according to the preset shape (such as the box unfolded diagram, irregular windows, handle holes, etc.).

[0003] When die-cutting cartons, flatbed die-cutting machines or rotary die-cutting machines are typically used. Pressure is applied to the cardboard using die-cutting blades to separate the finished carton from surrounding waste. This process generates a large amount of die-cutting waste, including outline waste, hole waste, and irregularly shaped waste. In practice, it is necessary to recycle and collect these waste materials.

[0004] Currently, waste from cardboard box die-cutting is typically collected and recycled using a negative pressure adsorption conveying method. Negative pressure suction vents are installed below or to the side of the die-cutting station, using airflow to adsorb the waste and transport it through pipes to a collection point. This is a relatively advanced automated processing method that enables continuous waste removal. However, during the die-cutting of cardboard boxes, the waste often contains liquid impurities such as moisture, ink residue, and adhesives, and is loose in shape and fluffy in volume. Therefore, during the negative pressure adsorption and transportation process of cardboard box die-cutting waste, heat treatment is required. However, existing negative pressure adsorption devices for cardboard box die-cutting waste are inconvenient to compact the waste before heating. This results in the fluffy cardboard box die-cutting waste occupying a large space during heating, and the air inside the fluffy waste causes slow heat transfer through the air layer, leading to uneven temperature distribution and poor heating effect. Therefore, this solution proposes a cardboard box die-cutting waste adsorption and transportation device and its heat treatment method to solve the above-mentioned technical problems. Summary of the Invention

[0049] This invention also proposes a heat treatment method for a cardboard box die-cutting waste adsorption and transportation device, which is completed by the aforementioned cardboard box die-cutting waste adsorption and transportation device, and includes the following steps:

[0050] S1. The negative pressure adsorption mechanism adsorbs and transports the cardboard box die-cutting waste, and then transfers the cardboard box die-cutting waste to the compaction operation chamber;

[0051] S2. Adjust the extension end of the cylinder to complete the compaction of the cardboard box die-cutting waste.

[0052] S3. Adjust the extension end of the cylinder to retract, complete the unloading of the compacted cardboard die-cutting waste, and let the cardboard die-cutting waste fall to the processing seat;

[0053] S4. Adjust the heater to heat the cardboard die-cutting waste on the processing seat to complete the heat treatment of the cardboard die-cutting waste.

[0054] The cardboard box die-cutting waste adsorption and transportation device and its heat treatment method of the present invention have the following advantages over the prior art:

[0055] (1) The cardboard die-cutting waste adsorption and transportation device of this application sets an upper compaction chamber between the discharge port of the negative pressure adsorption mechanism and the lower heating chamber, so that after the cardboard die-cutting waste is adsorbed and discharged, it can be compacted in the upper compaction chamber before being transported downwards to complete the heating treatment of the compacted cardboard die-cutting waste. By setting a second partition to divide the upper compaction chamber into a compaction operation chamber and a compaction matching chamber, the falling cardboard die-cutting waste can be concentrated and compacted in the compaction operation chamber and then transferred to the compaction matching chamber for the unloading treatment after compaction. By designing the compaction box frame, which includes a first plate, a first connecting frame, and a second plate, the compaction box frame has a box-like structure with open side walls. This design allows the cardboard die-cutting waste in the compaction operating cavity to fall smoothly into the inner side of the compaction box frame and work with the pressing assembly to compact the waste. A second spring is installed between the compaction box frame and the sliding contact plate, allowing the cylinder to extend further after the compaction box frame moves into the compaction operating cavity. The cylinder is then compressed by the second spring, driving the pressing assembly. This provides dual-drive operation for both the compaction box frame and the pressing assembly, requiring only one drive structure for ease of use. A cover plate is also included, allowing the cover plate to move and close the compaction operating cavity while the cylinder adjusts the compaction box frame's movement into the cavity. This prevents the cardboard die-cutting waste from falling further to the bottom of the cavity and prevents accidentally falling waste from obstructing the compaction box frame's return movement into the cavity, further enhancing usability. This allows the waste paper to be compacted before heating, making it easier to use.

[0056] (2) By setting two inner guide plates to connect the processing seat, the processing seat can rotate within the lower heating chamber, and the processing seat can maintain the sealing of its storage space during rotation. At the same time, by setting the processing seat to rotate, the cardboard die-cutting waste falling onto the processing seat can be adjusted to rotate back and forth, which can flatten the cardboard die-cutting waste on the processing seat, making it easier for the heater to heat the cardboard die-cutting waste on the processing seat evenly, which is convenient to use. By setting the discharge tray below one of the inner guide plates, when it is necessary to discharge cardboard die-cutting waste, it is only necessary to adjust the rotation of the processing seat to complete the discharge of cardboard die-cutting waste, which is convenient to use.

[0057] (3) By setting up a receiving box, after the cardboard die-cutting waste falls from the discharge port, the receiving box can first receive the cardboard die-cutting waste, and then adjust the rotation and lateral movement of the receiving box. By adjusting the lateral movement position of the receiving box, the cardboard die-cutting waste can fall flat on the processing seat, preventing the cardboard die-cutting waste on the processing seat from accumulating at the discharge port, and improving the heating effect of the heater on the cardboard die-cutting waste. By setting up a third motor and a shift drive gear, when the third motor drives the rotating shaft to rotate to drive the receiving box to rotate, the rotating shaft can synchronously drive the shift drive gear to rotate. Under the meshing of the shift mating gear plate, the rotating shift drive gear can drive the sliding seat to move laterally, thereby completing the synchronous drive processing of the rotation and shift of the receiving box, which is convenient to use.

[0069] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0070] like Figures 1-9As shown, the cardboard box die-cutting waste adsorption and transportation device of the present invention includes a negative pressure adsorption mechanism 1, a heat treatment chamber 2, a first partition 31, a second partition 32, an air outlet screen 33, a sliding mating plate 41, a cylinder 42, a compaction box frame 43, a pressing assembly 44, a connector 45, a second spring 46, a cover plate 51, an exhaust pipe 61, a first filter screen 62, a processing seat 71, and a heater 72. The first partition 31 is disposed inside the heat treatment chamber 2, dividing the inner cavity of the heat treatment chamber 2 into an upper compaction chamber 21 and a lower heating chamber 22 distributed vertically. The second partition 32 is disposed inside the upper compaction chamber 21, dividing the upper compaction chamber 21 into a horizontally distributed compaction operation chamber 211 and a compaction mating chamber 212. The negative pressure adsorption mechanism 1 and the press... The compaction chamber 211 is connected to the actual operation chamber and is used for negative pressure adsorption of cardboard die-cutting waste and to transfer the cardboard die-cutting waste to the compaction operation chamber 211. The exhaust screen 33 is set below the inner cavity of the compaction operation chamber 211 to block the cardboard die-cutting waste, and the height of the exhaust screen 33 is aligned with the first partition 31. The sliding mating plate 41 is slidably set inside the compaction mating chamber 212 and slides towards or away from the compaction operation chamber 211. The cylinder 42 is set on one side of the heat treatment chamber 2 and is used to drive the sliding mating plate 41 to slide. The second partition 32 has an assembly opening 321 for the compaction box frame 43 to pass through. The compaction box frame 43 is slidably set between the compaction operation chamber 211 and the compaction mating chamber 212, and the bottom wall of the compaction box frame 43 is flush with the exhaust screen. The mesh 33 abuts against the first partition 31; the compaction box frame 43 includes a first plate 431 and a second plate 432, the second plate 432 is fixedly connected to the first plate 431 through a first connecting frame 433, and there are four first connecting frames 433, which are respectively set at the four corners of the first plate 431; the pressing assembly 44 is slidably set on the first connecting frame 433, and slides towards or away from the first plate 431 to press and compact the cardboard die-cut waste in the compaction operation chamber 211; the connecting piece 45 passes through the second plate 432 and is fixedly connected to the pressing assembly 44 and the sliding mating plate 41; the second spring 46 is set between the second plate 432 and the sliding mating plate 41 to reset the second plate 432 relative to the sliding mating plate 41. The sliding position of the connecting plate 41; the first partition plate 31 has a discharge port 311, which is opposite to the compaction cavity 212 and is used for the compacted cardboard die-cutting waste to fall; the cover plate 51 is slidably disposed on the heat treatment box 2 and located above the compaction box frame 43, and is used to selectively cover the compaction operation cavity 211; the exhaust pipe 61 is connected to the compaction cavity 212, and the first filter screen 62 is disposed inside the compaction cavity 212 to cover the exhaust pipe 61; the processing seat 71 is disposed inside the compaction cavity 212 to receive the cardboard die-cutting waste falling from the discharge port 311, and the heater 72 is disposed below the processing seat 71 to heat the cardboard die-cutting waste on the processing seat 71.

[0071] In practice, a perforated cover 47 is provided on one side of the heat treatment chamber 2, and the cylinder 42 is located inside the perforated cover 47. A maintenance cover 10 is detachably connected to the heat treatment chamber 2, and the maintenance cover 10 is positioned opposite to the compaction cavity 212.

[0072] In practice, the negative pressure adsorption mechanism 1 adsorbs and transports the cardboard die-cutting waste, and transfers it to the compaction operation chamber 211. At this time, the cardboard die-cutting waste falls to the top of the air outlet screen 33 and is located inside the compaction box frame 43. The telescopic end of the adjusting cylinder 42 extends, at which time the cylinder 42 pushes the sliding mating plate 41 to move closer to the compaction operation chamber 211. Since the compaction box frame 43 abuts against the cavity wall of the compaction operation chamber 211, the compaction box frame 43 remains stationary, the second spring 46 is compressed, and the sliding mating plate 41 pushes the pressing assembly 44 to move closer to the first plate 431 through the connecting piece 45, completing the compaction treatment of the cardboard die-cutting waste. The telescopic end of cylinder 42 retracts, and the adjustment cover plate 51 moves to cover the compaction operation chamber 211. At this time, the sliding mating plate 41 moves away from the compaction operation chamber 211. The compressed second spring 46 first recovers its deformation. After the second spring 46 recovers its deformation, the pressing assembly 44 abuts against the second plate 432. The pressing assembly 44 drives the compaction box frame 43 to move away from the compaction operation chamber 211. After the compaction box frame 43 moves to the position opposite to the discharge port 311, the cardboard die-cutting waste falls from the discharge port 311 to the processing seat 71 through the compaction box frame 43. The heater 72 is adjusted to heat the cardboard die-cutting waste on the processing seat 71, completing the heat treatment of the cardboard die-cutting waste.

[0073] The cardboard box die-cutting waste adsorption and transportation device of this application, by setting an upper compaction chamber 21 between the discharge port of the negative pressure adsorption mechanism 1 and the lower heating chamber 22, allows the cardboard box die-cutting waste to be compacted in the upper compaction chamber 21 after being adsorbed and discharged, and then transported downwards to complete the heating treatment of the compacted cardboard box die-cutting waste. By setting a second partition 32 to divide the upper compaction chamber 21 into a compaction operation chamber 211 and a compaction mating chamber 212, the falling cardboard box die-cutting waste can be concentrated and compacted in the compaction operation chamber 211, and then transferred to the compaction mating chamber 212 for compaction and subsequent unloading processing. By setting the compaction box frame 43 to include a first plate 431, a first connecting frame 433, and a second plate 432, the compaction box frame 43 has a box structure with hollowed-out side walls. This design allows the cardboard die-cutting waste in the compaction operation chamber 211 to fall smoothly into the inner side of the compaction box frame 43 and work with the pressing assembly 44 to complete the compaction process of the cardboard die-cutting waste. By setting a second spring 46 between the compaction box frame 43 and the sliding mating plate 41, the cylinder 42 can continue to extend after the compaction box frame 43 moves into the compaction operation chamber 211 and is compressed by the second spring 46 to complete the driving process of the pressing assembly 44. This completes the dual driving process of the compaction box frame 43 and the pressing assembly 44, requiring only one driving structure for convenient use. By setting a cover plate 51, during the movement of the cylinder 42 adjusting the compaction box frame 43 into the compaction mating cavity 212, the cover plate 51 can be adjusted to close the compaction operation cavity 211, preventing the cardboard die-cutting waste from continuing to fall to the bottom of the compaction operation cavity 211. This prevents accidentally falling cardboard die-cutting waste from obstructing the compaction box frame 43 from returning to the compaction operation cavity 211, facilitating use. Therefore, this application allows for the compaction treatment of cardboard die-cutting waste before heating, making it convenient to use.

[0074] In specific implementation, the cross-sectional length of the compaction operation chamber 211 is L1, the cross-sectional length of the compaction mating chamber 212 is L2, L2≥2L1, the material discharge port 311 is opened at the end position of the first partition 31 aligning with the compaction mating chamber 212, and the length of the first connecting frame 433 is L3, L1≤L3≤2L1.

[0075] Preferably, L2 = 2L1, and L3 is slightly larger than L1.

[0076] This design maximizes the space of the compaction operation chamber 211 while realizing the compaction and unloading functions of the compaction box frame 43, making it convenient and practical.

[0077] In a preferred embodiment, the pressing assembly 44 includes a third plate 441, a pressing plate 442, a force sensor 443, and a first spring 444. The third plate 441 and the pressing plate 442 are slidably mounted on the first connecting frame 433. The end wall of the pressing plate 442 is provided with a sealing groove 4421 that seals against the first connecting frame 433. The connecting piece 45 is connected to the third plate 441, and the pressing plate 442 is used to compact the waste material from cardboard die-cutting. The force sensor 443 is mounted on the third plate 441, and the first spring 444 is mounted between the force sensor 443 and the pressing plate 442 for the sliding position of the pressing plate 442 relative to the third plate 441.

[0078] In practice, the force measuring device 443 can monitor the clamping force applied to the cardboard die-cutting waste by the third plate 441 in real time, thereby monitoring the compaction status of the cardboard die-cutting waste and preventing the cardboard die-cutting waste from being not compacted, or the cardboard die-cutting waste being compacted but the cylinder 42 continuing to extend, which would lead to damage to the device.

[0079] Preferably, the first connecting frame 433 is a rectangular frame, and the side wall of the third plate 441 is provided with a rectangular groove for the first connecting frame 433 to be inserted. This design is used to improve the sliding stability of the third plate 441, and at the same time improve the compaction and sealing performance of the third plate 441.

[0080] In a preferred embodiment, the device further includes a first mounting base 52, a drive toothed roller 53, and a first motor 54. The side wall of the heat treatment chamber 2 has a first assembly hole 23 through which the cover plate 51 passes, and the second partition 32 has a sealing insertion groove 322 for the cover plate 51 to be inserted. The first mounting base 52 is disposed on one side of the heat treatment chamber 2, and the drive toothed roller 53 is rotatably disposed on the first mounting base 52. The cover plate 51 has a mating groove 511 that meshes with the drive toothed roller 53. The first motor 54 is disposed on the first mounting base 52 and is used to drive the drive toothed roller 53 to rotate.

[0081] In specific implementation, the first motor 54 drives the toothed roller 53 to rotate, and the toothed roller 53 drives the cover plate 51 to move laterally through tooth meshing, thereby completing the automatic adjustment of the cover plate 51.

[0082] In a preferred embodiment, the system further includes a distributor 73, a drying air inlet pipe 74, and a second filter 75. The lower heating chamber 22 has multiple drying air outlets 24 on its wall, all located above the processing seat 71 and equidistantly distributed along the length of the heat treatment chamber 2. The distributor 73 is mounted on the heat treatment chamber 2, and its outlet is connected to the multiple drying air outlets 24. The drying air inlet pipe 74 is connected to the inlet of the distributor 73 and supplies drying air to the distributor 73. The second filter 75 is located inside the lower heating chamber 22 and covers the multiple drying air outlets 24.

[0083] In practice, external drying air is supplied to the distributor 73 through the drying air inlet pipe 74. After being split by the distributor 73, the air is blown out from each drying air outlet 24, completing the side heating treatment of the cardboard die-cutting waste on the processing base 71, thereby improving the heating efficiency of the cardboard die-cutting waste. By setting multiple drying air outlets 24, and equidistantly distributing the multiple drying air outlets 24, the coverage of the side drying air is improved, and the air is uniform and convenient to use.

[0084] In a preferred embodiment, the system further includes an inner guide plate 81, a discharge tray 82, and side limiting plates 83. The inner guide plate 81 is an arc-shaped plate, and there are two inner guide plates 81. The two inner guide plates 81 are respectively disposed on opposite sides of the inner cavity of the lower heating chamber 22, and the processing seat 71 is rotatably disposed between the two inner guide plates 81.

[0085] In practice, the side wall of the heat treatment chamber 2 is provided with a second motor 76 for driving the processing base 71 to rotate.

[0086] In practice, the outer side of the inner guide plate 81 is provided with a pad that is sealed and fitted to the wall of the heat treatment chamber 2. This design is to prevent the cardboard die-cutting waste from accidentally falling to the outer side of the inner guide plate 81 when the processing seat 71 rotates.

[0087] In practice, when the machining base 71 is in a horizontal position, both ends of the machining base 71 are located at the middle of the two inner guide plates 81, and the third assembly hole 811 is opened below the inner guide plate 81.

[0088] Two inner guide plates 81 are used to connect the processing seat 71, allowing the processing seat 71 to rotate within the lower heating chamber 22. During rotation, the processing seat 71 maintains the airtightness of its storage space. The rotatable processing seat 71 allows the cardboard die-cutting waste to fall onto it, and by adjusting the processing seat 71's reciprocating rotation, the waste can be evenly distributed, facilitating uniform heating by the heater 72. This design is convenient to use. A discharge tray 82 is positioned below one of the inner guide plates 81, allowing for easy unloading of cardboard die-cutting waste simply by adjusting the rotation of the processing seat 71. This design is also convenient to use.

[0089] In a preferred embodiment, the assembly further includes a receiving box 91 and a sliding drive assembly 92. The receiving box 91 is located inside the lower heating chamber 22 and above the processing seat 71. It is used to receive cardboard die-cutting waste material falling from the discharge port 311 and transfer it to the processing seat 71. The sliding drive assembly 92 is disposed on the heat treatment chamber 2 and is used to drive the receiving box 91 to move along the length of the heat treatment chamber 2 and to drive the receiving box 91 to rotate.

[0090] By setting up a receiving box 91, after the cardboard die-cutting waste falls from the discharge port 311, the receiving box 91 can first receive the cardboard die-cutting waste, and then adjust the rotation and lateral movement of the receiving box 91. By adjusting the lateral movement position of the receiving box 91, the cardboard die-cutting waste can fall flat on the processing seat 71, preventing the cardboard die-cutting waste on the processing seat 71 from accumulating in alignment with the discharge port 311, and improving the heating effect of the heater 72 on the cardboard die-cutting waste.

[0091] The sliding drive assembly 92 includes a sliding base 921, a second mounting base 922, a second connecting frame 923, a third motor 924, a rotating shaft 925, a shifting drive gear 926, and a shifting mating gear plate 927. A sliding hole 26 is provided on one side of the heat treatment chamber 2. The sliding base 921 is slidably disposed at the sliding hole 26 and covers the sliding hole 26. The second mounting base 922 is fixedly connected to the sliding base 921 via the second connecting frame 923. The third motor 924 is mounted on the rotating shaft 925. The rotating shaft 925 is fixedly connected to the output shaft of the third motor 924 and passes through the sliding base 921 and the sliding hole 26, and is fixedly connected to the receiving box 91. The shifting drive gear 926 is fixedly sleeved on the rotating shaft 925. The shifting mating gear plate 927 is disposed on the heat treatment chamber 2, and the shifting drive gear 926 meshes with the shifting mating gear plate 927.

[0092] By setting a third motor 924 and a shift drive gear 926, when the third motor 924 drives the rotating shaft 925 to rotate in order to drive the receiving box 91 to rotate, the rotating shaft 925 can synchronously drive the shift drive gear 926 to rotate. Under the meshing engagement of the shift mating tooth plate 927, the rotating shift drive gear 926 can drive the sliding seat 921 to move laterally, thereby completing the synchronous drive processing of the rotation and shift of the receiving box 91, which is convenient to use.

[0093] In a preferred embodiment, the negative pressure adsorption mechanism 1 includes a cyclone separator 11, a discharge conveying pipe 12, an inlet conveying pipe 13, a suction hopper 14, a suction hood 15, an inner pad 16, and a feeding roller 17. The discharge conveying pipe 12 is connected to the discharge port of the cyclone separator 11 and to the compaction operation chamber 211; the inlet conveying pipe 13 is connected to the inlet of the cyclone separator 11, and the suction hopper 14 is located at the end of the inlet conveying pipe 13. 15 is set at the end of the suction hopper 14; the air inlet conveying pipe 13 is a rectangular pipe, and two inner pads 16 are set on opposite sides of the inner cavity of the air inlet conveying pipe 13. The inner pads 16 extend to the suction hopper 14, and the inner pads 16 form an arc-shaped bent wall 161; the end of the inner pads 16 is provided with an assembly groove 162, which is an arc-shaped groove, and the feeding roller 17 is rotatably set inside the assembly groove 162. The side wall of the feeding roller 17 is provided with multiple feeding claw plates 171.

[0094] Preferably, the feeding claw plate 171 is in contact with the wall of the assembly groove 162. This design prevents the feeding claw plate 171 from squeezing the cardboard die-cutting waste into the inner side of the assembly groove 162. By setting the air inlet conveying pipe 13 as a rectangular tube, it is convenient to perform the sealing assembly of the inner pad block 16, and at the same time, it is convenient to design the feeding roller 17 and to use it.

[0095] This invention also proposes a heat treatment method for a cardboard box die-cutting waste adsorption and transportation device, which is completed by the aforementioned cardboard box die-cutting waste adsorption and transportation device, and includes the following steps:

[0096] Step 1: The negative pressure adsorption mechanism 1 adsorbs the waste paperboard die-cutting material and transfers it to the compaction operation chamber 211. At this time, the waste paperboard die-cutting material falls to the top of the air outlet screen 33 and is located inside the compaction box frame 43.

[0097] Step 2: Adjust the extension end of cylinder 42 to extend. At this time, cylinder 42 pushes sliding mating plate 41 to move closer to compaction operation chamber 211. Since compaction box frame 43 abuts against the cavity wall of compaction operation chamber 211, compaction box frame 43 remains stationary. The second spring 46 is compressed. Sliding mating plate 41 pushes pressing assembly 44 to move closer to first plate 431 through connector 45, thus completing the compaction treatment of carton die-cutting waste.

[0098] Step 3: Adjust the retraction end of cylinder 42 to retract, and adjust the cover plate 51 to move to cover the compaction operation chamber 211. At this time, the sliding mating plate 41 moves away from the compaction operation chamber 211. The compressed second spring 46 first recovers its deformation. After the second spring 46 recovers its deformation, the pressing assembly 44 abuts against the second plate 432. The pressing assembly 44 drives the compaction box frame 43 to move away from the compaction operation chamber 211. After the compaction box frame 43 moves to the position opposite to the discharge port 311, the carton die-cutting waste falls from the discharge port 311 to the processing seat 71 through the compaction box frame 43.

[0099] Step 4: Adjust heater 72 to heat the cardboard die-cutting waste on processing seat 71 to complete the heat treatment of cardboard die-cutting waste.

[0100] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
