In order to facilitate collection of shredded paper scraps, a shredding bag is paved in a paper scraps shredding barrel of the existing shredder, and is used for uniformly collecting the paper scraps falling from a chip removal port 15. Because the self weight of paper bits is lighter, the paper bits that drop behind can't carry out the compaction with the paper bits of bottom through the weight of self to lead to whole volume big, and the paper bits occupation space is big, extravagant garrulous paper bag's dress paper space, extravagant garrulous paper bag, inconvenient clearance. When the cleaning is carried out manually, a large amount of powdery paper scraps exist in the crushed paper bags, the powdery paper scraps are easy to float in the air, the environment is polluted, and meanwhile cleaning staff easily inhale the powdery paper scraps, so that the health is impaired.
According to the paper shredder with the paper pressing function, the bag opening of the shredded paper bag is folded and pressed through the bag folding and sealing device 20, a closed vacuumizing space is formed in the shredded paper bag, the vacuumizing nozzle 50 of the vacuumizing device 40 is communicated with the vacuumizing space, the shredded paper bag is vacuumized, negative pressure is formed in the shredded paper bag, paper scraps in the shredded paper bag are compacted through the negative pressure, the compacting effect is good, the paper filling space of the shredded paper bag is fully utilized, the use of the shredded paper bag is reduced, and resources are saved. The whole volume of the crushed paper bag compacted by crushed paper is reduced, and the crushed paper bag is more convenient to clean. The bag closing device 20 closes the bag mouth of the crushed paper bag, seals the crushed paper bag at the same time, prevents the powdery paper scraps in the crushed paper bag from floating in the air to cause environmental pollution, and can also prevent cleaning staff from sucking the powdery paper scraps, thereby being environment-friendly.
The bag closing device 20 is used for closing the bag opening of the crushed paper bag and heat-sealing the bag opening of the crushed paper bag. The vacuum pumping device 40 is used for pumping air in the paper shredding bag, so that negative pressure is formed in the paper shredding bag, and paper scraps are compacted under the action of the negative pressure. The bag closing and sealing device 20 and the vacuumizing device 40 cooperate to complete the bag opening closing, heat sealing and compacting of the crushed paper bags.
Preferably, the shredder head 10 is provided with a mounting base 11, the mounting base 11 is provided with an extension opening 12, the extension opening 12 is arranged above a position corresponding to the press fit position of the bag pressing rod 33 and the heating rod 30, the air suction part 41 is mounted on the mounting base 11, the air suction nozzle 50 is slidably mounted on the outer side of the air suction part 41, or the air suction nozzle 50 is rotatably mounted on the inner side of the air suction part 41, and when the vacuumizing device 40 vacuumizes a shredded paper bag, the air suction nozzle 50 is inserted between the bag pressing rod 33 and the heating rod 30 through the extension opening 12. Preferably, the vacuumizing device 40 is arranged above the bag opening collecting device, the vacuumizing device 40 is preferably arranged in the paper shredder head 10, and the installation space is optimized, so that the arrangement positions of all parts in the paper shredder are reasonable. Suction nozzle 50 is slidably mounted to suction portion 41, and suction nozzle 50 is in press fit with heat generating rod 30 and bag pressing rod 33, respectively, through outlet 12 as it moves up and down.
The matching relationship between the suction nozzle 50 and the heat sealing portion 31 at least includes the following two cases, wherein the first case is that after the suction nozzle 50 sucks the crushed paper bag, the suction nozzle 50 stops sucking the crushed paper bag, and the heat sealing portion 31 heat seals the mouth of the crushed paper bag. Specifically, when the vacuum-pumping device 40 pumps the crushed paper bags, the air pumping nozzle 50 is inserted between the bag pressing rod 33 and the heating rod 30, and the air pumping nozzle 50 is clamped between the bag pressing rod 33 and the heating rod 30; when the bag closure device 20 is closing the bag, the suction nozzle 50 is moved out between the bag pressing bar 33 and the heat generating bar 30. I.e., the lowermost end of the suction nozzle 50 slides over the heat seal 31, the suction nozzle 50 ceases operation. Preferably, the lowermost end of the suction nozzle 50 is moved out between the bag pressing bar 33 and the heating bar 30, the bag pressing bar 33 and the heating bar 30 can press the crushed paper bags more tightly, and the sealing effect of the heat sealing part 31 on the crushed paper bags is better.
In the second case, after the air suction nozzle 50 finishes the air suction in the crushed paper bag, the heat sealing part 31 is started to heat-seal the bag mouth of the crushed paper bag, and the air suction nozzle 50 keeps continuously sucking the air in the crushed paper bag until the heat sealing part 31 finishes the heat sealing, and the air suction nozzle 50 stops sucking the air. Specifically, when the vacuum-pumping device 40 pumps the crushed paper bags, the air pumping nozzle 50 is inserted between the bag pressing rod 33 and the heating rod 30, and the air pumping nozzle 50 is clamped between the bag pressing rod 33 and the heating rod 30; when the bag sealer 20 seals the bag, the suction nozzle 50 is clamped to the bag-pressing bar 33 and the heat generating bar 30, and the lowermost end of the suction nozzle 50 is located above the heat seal 31. I.e., the suction nozzle 50 is clamped between the sponge portion 32 and the bag-pressing strip 34, the suction nozzle 50 continues to suck air until the heat seal 31 is completed to heat seal the bag.
Because the air suction nozzle 50 is inserted into the bag mouth of the paper shredding bag during vacuumizing, the bag mouth of the paper shredding bag is folded through the bag collecting and sealing part, a closed vacuumizing space is formed in the paper shredding bag, and the air suction nozzle 50 is clamped at the bag collecting and sealing part while the paper shredding bag is folded, at the moment, the air suction nozzle 50 is communicated with the vacuumizing space, and the air suction nozzle 50 pumps air in the paper shredding bag. After the evacuation is completed, the heat sealing of the mouth of the crushed paper bag is started, the bag closing and sealing part at this time still closes the mouth of the crushed paper bag, and in the first case, the suction nozzle 50 completely withdraws the bag closing and sealing part, and the heat sealing part 31 heat seals the mouth of the crushed paper bag. In this way, the closing and compacting effects of the bag closing part on the crushed paper bags are better due to the withdrawal of the suction nozzle 50, so that the heat sealing effect of the bag opening of the crushed paper bags is good; in the second case, the suction nozzle 50 is still kept in the bag-collecting sealing part to continuously vacuumize the inside of the crushed paper bag, so that the heat-sealing part 31 seals the crushed paper bag in a heat-sealing way under the condition that the negative pressure state in the crushed paper bag is continuously kept good, the good negative pressure paper-pressing state in the crushed paper after sealing is kept, and the paper-pressing effect in the crushed paper bag after sealing is good.
More specifically, the bag pressing bar 33 is provided with a bag pressing bar 34 protruding toward the side face of the heating bar 30, the side face of the heating bar 30 facing the bag pressing bar 33 is provided with a sponge portion 32 and a heat seal portion 31, and the sponge portion 32 is provided protruding toward the bag pressing bar 33. Preferably, the sponge portion 32 is made of a soft material such as sponge, silica gel, or the like. The bag pressing strip 34 is made of relatively soft materials such as silica gel. There are two kinds of positions of the sponge portion 32 and the heat-seal portion 31, the first is that the sponge portion 32 is at the upper portion, the heat-seal portion 31 is at the lower portion, and the second is that the heat-seal portion 31 is at the upper portion, and the sponge portion 32 is at the lower portion. In the second case, the matching relationship between the air suction nozzle 50 and the heat sealing portion 31 is selected, and the positional relationship between the sponge portion 32 and the heat sealing portion 31 should be selected to be the second case, that is, the heat sealing portion 31 is at the upper portion and the sponge portion 32 is at the lower portion, so that when the heat sealing portion 31 seals the opening of the paper shredding bag, the sponge portion 32 and the bag pressing strip 34 continuously press the opening of the paper shredding bag, and air leakage in the paper shredding bag is prevented.
When the heating rod 30 and the bag pressing rod 33 are pressed, the bag pressing strip 34 is in press fit with the sponge part 32, and the suction nozzle 50 is clamped between the bag pressing strip 34 and the sponge part 32; since the bag pressing bar 34 is arranged on the bag pressing bar 33 in a protruding manner, the sponge part 32 is arranged on the heating bar 30 in a protruding manner, when the bag pressing bar 33 and the heating bar 30 are relatively close, the bag pressing bar 34 and the sponge part 32 are firstly abutted, the suction nozzle 50 is inserted into the mouth of the paper shredding bag, the suction nozzle 50 is pressed between the bag pressing bar 33 and the heating bar 30 through the bag pressing bar 34 and the sponge part 32, and meanwhile, the paper shredding bag is folded between the bag pressing bar 33 and the heating bar 30. Preferably, both the bag-pressing strip 34 and the sponge portion 32 are made of soft materials, and because both the bag-pressing strip 34 and the sponge portion 32 are made of soft materials, when the suction nozzle 50 is clamped between the sponge portion 32 and the bag-pressing strip 34, the sponge portion 32 and the bag-pressing strip 34 enclose the suction nozzle 50, so that the compactness of the vacuum-pumping space in the crushed paper bag is better after the heating rod 30 and the bag-pressing rod 33 close the crushed paper bag.
When the heat bar 30 heat seals the crushed paper bags, the bag pressing strips 34 are respectively in press fit with the sponge part 32 and the sealing part, and the suction nozzle 50 is positioned above the bag collecting and sealing device 20. When the heat-generating rod 30 heat-seals the mouth of the paper shredding bag, the heat-sealing portion 31 is pressed against the bag pressing strip 34, the mouth of the paper shredding bag is pressed, the paper shredding bag is stuck to the heat-sealing portion 31, and the paper shredding bag is heat-melted to form a seal.
