Abstract
The utility model relates to a paper shredder with a safety protection device at the paper inlet, which belongs to the technical field of the safety protection device of the paper shredder. A driving roller and a driven roller are arranged at the lower part of the paper inlet at the head of the paper shredder, both ends of the driven roller are respectively inserted in a sliding groove, the head of the paper shredder is provided with at least one switch used for controlling the closing down of the paper shredder, the switch is fixed outside the driven roller, when the inserting paper is excessively thick or the paper is inserted into the paper inlet by hand, the paper or the hand primarily touches the driving roller and the driven roller, the driven roller is pushed away, at the moment, the switch is touched by the press of the driven roller, the switch is closed, the cutter of the paper shredder is controlled by a controlling circuit of the paper shredder, to stop the rotation, thus the excessive thick paper can be prevented from putting, simultaneously, the hands can be effectively prevented from being twisted and injured by the cutter, and the potential safety hazard at the paper inlet of the paper shredder can be eliminated.
Description
Technical field:
The utility model relates to the safety guard technical field of shredder, refers in particular to a kind of shredder of paper inlet band safety guard.
Background technology:
Shredder work the time be rely in its shredded paper head two in opposite directions the shearing of the cutters of rotation cooperate and paper pulverized, shredder is when work, if people's hand mistake is inserted in the paper inlet of shredded paper head, the cutter in the shredded paper head then can be hindered people's hand strand, has potential safety hazard.
The utility model content:
The purpose of this utility model is to provide at the deficiencies in the prior art a kind of shredder of paper inlet band safety guard, and when staff inserted the paper inlet of shredded paper head, shredder was then shut down at once, had eliminated the potential safety hazard at paper inlet of paper shredder place.
For achieving the above object; the utility model is achieved through the following technical solutions: the paper inlet safety guard of shredder; it is characterized in that: the paper inlet below of shredded paper head is provided with drive roll and driven voller; drive roll is connected with the transmission mechanism of shredder; the two ends of driven voller are plugged on respectively in the chute; be provided with the elastic component that at least one pushes driven voller to drive roll in the shredded paper head; the shredded paper head is provided with at least one and is used to control the switch that shredder is shut down, and this switch is fixed on the outside of driven voller.
Described drive roll and driven voller level are arranged side by side.
Described elastic component is shell fragment or spring.
Described switch is fixed on the plate that can regulate its horizontal level.
Described drive roll and driven voller are rubber roll.
One end of described drive roll is fixed with the rubber roll gear, and the rubber roll gear is by travelling gear and the knife shaft gear engagement fit that is fixed on the cutter shaft.
The beneficial effects of the utility model: the utility model is to be provided with drive roll and driven voller below the paper inlet of shredded paper head; the two ends of driven voller are plugged on respectively in the chute; the shredded paper head is provided with at least one and is used to control the switch that shredder is shut down; this switch is fixed on the outside of driven voller; when inserting the blocked up or staff insertion paper inlet of paper; what paper or staff at first touched is drive roll and driven voller; driven voller can be open; at this moment; switch is subjected to the driven voller compressing and is touched; switch closure; the cutter that the control circuit of shredder is then controlled shredder stops operating; thereby prevent to put into blocked up paper, also can effectively prevent that cutter from twisting the hand of hurting sb.'s feelings, and eliminated the potential safety hazard at paper inlet of paper shredder place simultaneously.
Description of drawings:
Accompanying drawing 1 is a structural representation of the present utility model;
Accompanying drawing 2 is the cutaway view in A-A cross section in the accompanying drawing 1;
Structural representation when accompanying drawing 3 is open pressing switch for the driven voller in the accompanying drawing 2;
Accompanying drawing 4 is the cutaway view in B-B cross section in the accompanying drawing 1;
Structural representation when accompanying drawing 5 is open for the driven voller in the accompanying drawing 4.
The specific embodiment:
Embodiment sees accompanying drawing 1 to 5, the paper inlet safety guard of shredder, it is that paper inlet 1 below of shredded paper head is provided with drive roll 2 and driven voller 3, drive roll 2 and driven voller 3 levels are arranged side by side, drive roll 2 and driven voller 3 be positioned at paper inlet 1 under.
Described drive roll 2 and driven voller 3 are rubber roll, and rubber roll is that soft material is made.
Described drive roll 2 be by bearing fixing in the shredded paper head, one end of drive roll 2 is fixed with rubber roll gear 8, rubber roll gear 8 is by travelling gear 9 and knife shaft gear 10 engagement fit that are fixed on the cutter shaft, thereby an end of drive roll 2 is connected with the transmission mechanism of shredder.When shredded paper, utilize the knife shaft gear 10 on the existing cutter shaft of shredder to drive drive rolls 2 rotations, do not need to dispose in addition independently that power set drive, simple and compact for structure.When shredded paper, drive roll 2 drives driven voller 3 rotations, will be rolled onto the cutter 4 of its below from the paper that paper inlet 1 is come in downwards.
The two ends of described driven voller 3 are plugged on respectively in the chute, (not drawing among the figure), make driven voller 3 have the certain displacement space in the horizontal direction, be provided with at least one in the shredded paper head and push driven voller 3 elastic component 5 of drive roll 2 to, described elastic component 5 is shell fragment or spring.
Described shredded paper head is provided with at least one and is used to control the switch 6 that shredder is shut down, and this switch 6 is fixed on the outside of driven voller 3.
Described switch 6 is to insert in the control circuit of shredder, when inserting the blocked up or staff insertion paper inlet 1 of paper, what paper or staff at first touched is drive roll 2 and driven voller 3, driven voller 3 can be open, and at this moment, switch 6 is subjected to driven voller 3 compressings and is touched, switch 6 closures, the cutter 4 that the control circuit of shredder was then controlled shredder when switch 6 was closed stops operating, thereby prevents to put into blocked up paper, also can effectively prevent the cutter 4 strands hand of hurting sb.'s feelings simultaneously.In addition, after pressing place of paper through drive roll 2 and driven voller 3, paper can be tensioned, paper can be straightened in pressing place of drive roll 2 and driven voller 3 and the part between the cutter 4, the sound of shredder when coil paper can diminish, therefore, at shredder during at shredded paper, the noise in the time of effectively reducing the shredder shredded paper.
Described switch 6 is fixed on the plate 7 that can regulate its horizontal level, and plate 7 is arranged on the outside of driven voller 3, and the horizontal level of regulating plate 7 can be regulated the distance between driven voller 3 and the switch 6, promptly is the Safe width of adjusting paper inlet 1.
Certainly, described switch 6 can also be the inductive switch of other form, as light-operated switch, infrared sensing switch, magnetic induction switch etc., inductive switch is used to respond to driven voller 3 horizontal displacement that goes out pushed outwards, when driven voller 3 arrives the displacement of setting, the cutter 4 that inductive switch is then controlled shredder stops operating, and perhaps directly cuts off the power supply of shredded paper, thereby reaches the security hidden trouble of the paper inlet 1 of eliminating shredder.
The above only is preferred embodiment of the present utility model, so all equivalences of doing according to the described structure of the utility model patent claim, feature and principle change or modify, is included in the utility model patent claim.
