Abstract
The utility model belongs to office appliances, relating to an automatic envelope opener provided with a touch switch, a cutting knife of a circular saw and a DC motor. When an envelope entering a letter-inserting gap impels a touch switch, the touch switch is switched on, and the motor drives the cutting knife of the circular saw to relatively rotate seizing the envelope edge, so that the envelope is pulled through the cutting knife and simultaneously the envelope end part with the length of 1 mm to 2 mm is cut away, and as a result, the goal of automatically opening the envelope is achieved.
Description
The utility model belongs to a kind of office accommodation, particularly a kind of envelope device of opening automatically.
The existing envelope device of opening is formed (ZL93210433.9) by knife rest and blade, during use letter put into and insert the letter groove, draw forward with hand, point of a knife is scratched envelope, weak point is, the strength that needs armrest with envelope haul advance and controlling party to, do not break away from the method that hand-held blade is scratched envelope, just that blade is fixing.
The purpose of this utility model provides a kind of envelope device of opening automatically, behind envelope contact touch switch, can pass through automatically, and the envelope port is downcut 1～2mm, makes the unlatching of envelope convenient and rapidly neat.
The technical solution of the utility model is as follows: a kind of envelope device of opening automatically, form by upper box cover, lower casing, support and cutting knife, and it is characterized in that: touch switch, touch switch baffle plate, direct current energising motivation, reduction box and battery case are housed on the support; Touch switch is made up of lever and spring leaf, and the touch switch baffle plate is installed in the front of spring leaf, is fixed on the support with screw, and when spring leaf during by pressing, the battery in the battery case, spring leaf and motor constitute current loop; Travelling gear is arranged in the reduction box, and the driving shaft of motor links to each other with driving gear, driving gear and driven gear engagement, and driven gear is connected to the cutter shaft of cutting knife respectively.
The utlity model has following advantage and effect, owing to adopted touch switch and annular saw cutting knife, thus thoroughly changed the mode of manually opening envelope, counterrotating two annular saw cutting knifes are nipped envelope edge, make envelope automatically by cutting knife, easy to operate and rapid, neat, attractive in appearance.
The drawing of accompanying drawing is described as follows:
Fig. 1, the utility model structure chart.
Fig. 2 a, annular saw cutting knife and reduction box partial cross-sectional side-elevation view.
Fig. 2 b, annular saw cutting knife and touch switch front elevation.
Fig. 3 a, touch switch structure chart.
Fig. 3 b, touch switch and motor circuit connection layout.
Be described further below in conjunction with drawings and Examples: the utility model is made up of upper box cover (8), lower casing (9), support (10) and annular saw cutting knife (1), (2).After upper box cover (8) both sides respectively have a spatula (81) and (82) to fasten with lower casing (9), slit (83) that can supply envelope to pass through of positive formation, touch switch (3) is housed on the support (10), touch switch baffle plate (6), dc motor (4), reduction box (5) and battery case (7), there is a spring (11) annular saw cutting knife (1) back, it is close to annular saw cutting knife (1) and (2), annular saw cutting knife (2) back has a jump ring (12) with fixed circular saw cutting knife (2), the cutter shaft of annular saw cutting knife (1) and (2) and the gear in the reduction box (51), (52) connect.Gear (53) and gear (52) engagement, gear (53) is driven by dc motor (4); Touch switch is by lever (31) and spring leaf (32); (33) form; touch switch baffle plate (6) is installed in spring leaf (32); (33) front and be fixed on the support with screw; with the protection touch switch; when envelope is believed slit (83) by inserting; when promoting lever (31); lever (31) is with two spring leafs (32); (33) pressing; motor (4) and the battery in the battery case (7) are connected; motor (4) driven wheel (53); by the gear (51) in gear (53) the drive reduction box (5); (52); the edge of envelope is bitten in the relative rotation with (2) of annular saw cutting knife (1); and drop envelope and in the middle of annular saw cutting knife (1) and (2), pass through; simultaneously the envelope end is cut 1～2mm, thereby reach out the purpose of envelope.
