Abstract
Description
Technical Field
[0001] This utility model relates to the field of paper product processing technology, and in particular to a device for collecting waste materials from paper product processing. Background Technology
[0002] Paper products are widely used in daily life, such as cardboard, cartons, and paper shells. During paper product processing, numerous cutting operations are inevitable, generating a significant amount of waste. This waste mainly consists of two types: small fragments and relatively large strips or pieces of paper. Paper waste is flammable and increases dust levels in the workshop, causing pollution and harming the health of workers. Therefore, every effort is made to remove paper waste.
[0003] Paper material cutting is primarily accomplished on a workbench using a cutting device. Therefore, the resulting paper waste is mostly handled by vacuum suction devices, similar to vacuum cleaners. However, under negative pressure, fine debris and larger paper strips or pieces are often sucked up together, causing blockages in the vacuum suction device's pipes or suction points. This necessitates manual cleaning, increasing maintenance frequency. Some patent applications focus on addressing blockages, often employing various structures to clear them. However, this increases structural complexity, and the dusty working environment, due to the constant flow of paper scraps, can negatively impact the lifespan of complex structures.
[0004] This invention aims to provide a waste collection device for paper product processing, which can effectively collect scraps, paper strips, and paper pieces, and has a simple structure, is easy to maintain, and is not prone to clogging. Utility Model Content

[0022] To provide a better understanding of the purpose, structure, features, and functions of this utility model, detailed descriptions are provided below with reference to specific embodiments.
[0023] Figure 1 The diagram shown is an external schematic of a waste collection device for paper product processing according to an embodiment of the present invention. Figure 2 The diagram shown is a schematic diagram of the internal structure of a waste collection device for paper product processing according to an embodiment of this utility model.
[0024] like Figure 1 and Figure 2 As shown, this utility model embodiment provides a waste collection device for paper product processing, including: a screw conveyor 3, which extends horizontally and includes a housing 33 and a spiral auger 34 disposed in the housing 33. An inlet 31 and an outlet 32 are respectively provided at both ends of the screw conveyor 3. A cover 4 is provided at the inlet 31 of the screw conveyor 3, with the opening of the cover 4 facing the workbench 1 for paper product processing; a first vacuum cleaner (the suction pipe 5 of the first vacuum cleaner), with the air inlet of the first vacuum cleaner disposed on the cover 4 and facing the opening of the cover 4, and a baffle 41 provided on the air inlet; and a collection box 6, which is disposed at the outlet 32 of the screw conveyor 3.
[0025] Figure 3 As shown Figure 2 A schematic diagram illustrating the operation of the embodiment is shown. Figure 3 As shown, the first vacuum cleaner provides vacuum suction, pulling the paper waste 2. The baffle 41 prevents the paper waste 2 from entering the suction pipe 5 of the first vacuum cleaner. When the paper waste 2 reaches the shield 4, it is crushed and conveyed by the auger 34. Because the auger 34 rotates continuously, the paper waste 2 does not accumulate at the baffle 41, nor does it affect the unobstructed flow of the baffle 41 and the suction pipe 5 of the first vacuum cleaner. Therefore, the embodiment shown in the figure can operate continuously without frequent processing of accumulated waste. Inside the screw conveyor 3, the paper waste 2 is crushed and conveyed, finally exiting from the discharge port 32 and entering the collection box 6. In the embodiment shown in the figure, the paper waste is crushed and conveyed inside the screw conveyor 3, preventing leakage to the outside.
[0026] Furthermore, such as Figure 2 As shown, a spraying device 7 is installed near the shield 4, with the spray nozzles of the spraying device 7 facing the auger 34 of the screw feeder 3. Figure 2As shown, at the location of the spray device 7, micro-holes 71 are provided on the housing 33. This allows water sprayed by the spray device to enter the housing 33 through the micro-holes 71, while also preventing leakage of the paper waste 2. By dripping water into the housing 33, the paper waste 2 is moistened, facilitating its clumping, reducing dust, and allowing it to be smoothly discharged from the outlet 32. The spray device 7 can also be directly installed at the location of the shield 4.
[0027] Figure 4 The diagram shown is an operational schematic of another embodiment of the present invention. Further, as... Figure 4 As shown, soft bristles 341 are provided on the edge of the auger 34 below the shield 4. The soft bristles 341 increase the adsorption area of the auger 34, facilitating the entrainment and adsorption of paper waste 2. Simultaneously, the soft bristles 341 continuously swing under the action of the auger 34, wiping and cleaning the baffle 41 and preventing it from becoming clogged. When the auger 34 rotates to its lower position, the soft bristles 341 are compressed, ensuring the normal operation of the auger 34 is not affected.
[0028] Furthermore, such as Figure 4 As shown, a second vacuum cleaner (the suction pipe 8 of the second vacuum cleaner) is installed above the shield 4. The air inlet of the second vacuum cleaner is set to face the workbench 1, and the air intake direction of the second vacuum cleaner is set to be inclined relative to the horizontal direction. By setting up the second vacuum cleaner, the effective distance for adsorbing paper waste can be increased, and the adsorption force on paper waste can be enhanced.
[0029] Furthermore, such as Figure 5 As shown, a flexible hose 9 is provided at the outlet of the shield 4, with the port of the flexible hose 9 facing a specific position on the workbench, so as to perform suction cleaning on the specific position.
[0030] The waste collection device for paper product processing provided in this embodiment can effectively collect paper scraps, paper strips, and paper pieces. It can effectively clean up paper scraps and also effectively process them. It has a simple structure, is easy to maintain, and is not prone to clogging.
