Specific embodiment

The utility model provides a kind of cutter of receipt printing machine, for make the purpose of this utility model, technical solution and Effect is clearer, clear, and the utility model is further described as follows in conjunction with drawings and embodiments.It should be appreciated that Specific embodiment described herein only to explain the utility model, is not used to limit the utility model.

The utility model provides a kind of cutter of receipt printing machine referring to FIG. 1 to FIG. 4,.In the visual angle Fig. 1, cutter In cut state.For the ease of observation, elastic cushion block is filled in Fig. 1, Fig. 2 and Fig. 3.Attached drawing is only used for described in explanation The structural principle of the cutter of receipt printing machine, it is not proportional to actual product.

The cutter of the receipt printing machine includes substrate 1, knife rest 3 and cutter 5.Substrate 1 is arranged there are two guide hole 101, The both ends of knife rest are respectively arranged with a guide rod 24, and every guide rod 24 is passed through from a guide hole 101 respectively, two guide rods 24 it Between be provided with a cross bar 23.By attached drawing it is found that two guide rods are set in parallel, knife rest is located above substrate, and cross bar is located at Below substrate；Cross bar, guide rod and knife rest can be moved linearly together.There are two elastic cushion block 4, two elasticity for the setting of knife rest bottom Cushion block 4 is located at the two sides of cutter 5；Cutter is corresponded on substrate 1 is provided with a straight trough 102, blade (such as Fig. 1 of cutter 5 Shown in middle dotted line 501) it is opposite with straight trough 102；A motor 20 is additionally provided on substrate 1, the main shaft 201 of the motor connects one Crank 21, is provided with a connecting rod 22 between the crank 21 and cross bar 23, crank 21 and cross bar 23 can be rotated with connecting rod 22 respectively Ground connection.When practical set, two threaded holes 109 can be opened up respectively in basic two sides, in order to pass through screw or bolt It is fixed in buying a ticket.

Preferably, above-mentioned two elastic cushion block 4 is made of sponge, naturally it is also possible to be made of other elastic materials.Locating When uncut state, the bottom of two elastomer blocks and the blade of cutter are concordant.Under cut state, elastic cushion block plays platen It acts on and impression will not be generated.

Preferably, a groove (in figure view less than) is provided on the knife rest 3, the knife spine of cutter (that is: is not set Set the part of blade) it is set in the groove, the cutter is connect with knife rest by bolt 31, it may be assumed that cutter is removably set It sets on knife rest, replaces cutter with can be convenient in subsequent use.

Preferably, it is opened up on cutter 5 there are two threaded hole (not observing in figure), accordingly opens up that there are two waists on knife rest Type hole 30.It is clearance fit between cutter and groove, behind the position of appropriate adjustment cutter, by two screws 31 in practical application It is screwed into corresponding threaded hole again after waist-shaped hole 30 and fixes cutter.It is of course also possible to waist-shaped hole is opened up on cutter, and Connecting hole is opened up on knife rest, the position of adjustment cutter also may be implemented, and cutter and tool holder support are connected with.

Further, the length of the straight trough 102 is greater than the length of cutter 5, and the width of straight trough 102 is greater than the thickness of cutter 5 Degree.The setting is convenient for cutter when actual motion that can be successfully inserted in straight trough.

When practical set, the motor 20 is arranged in a mounting base 29, and the mounting base 29 is fixed on substrate 1, from And play the role of stablizing support to motor.

As shown in Fig. 2, further, the main shaft 201 of the motor passes through substrate and connect with crank 21, i.e., motor 20 is set It sets in the side of substrate 1, the other side of substrate 1 is arranged in crank 21, so that the installation space of motor and crank minimizes.

Further, the motor 20 is located at the middle on 1 length direction of substrate, connecting rod 22 and 23 junction of cross bar position Middle on 23 length direction of cross bar.When setting is so that connecting rod drives cross bar movement in this way, cross bar is more uniformly stressed, Guarantee that guide rod and knife rest steadily move, guarantees cutting accuracy.

Further, two guide rods 24 are round bar, and accordingly, two guide holes 101 on substrate 1 are circular hole, convenient for practical When assembly, guide rod can be easily inserted into guide hole.

In actual use, the cutter setting of above-mentioned receipt printing machine is in receipt printing machine 90 (printing receipt or similar bill Receipt printing machine) in and at the ticket outlet, the motor is connected with the controller of receipt printing machine.Page 91 completes printing in receipt printing machine Pass through below cutter afterwards, controller controls motor rotation to carry out cutting ticket.Paper roll, feeding-in roll, print head, glue are not drawn into figure The conventional components such as roller, sensor, these components are not also within the protection scope of the present utility model.

Working principle described briefly below: the crank 21, connecting rod 22, cross bar 23, guide rod 24 and substrate 1 form slide crank Block mechanism, the every rotation of motor 20 one week, 24 straight reciprocating motion of guide rod is primary, it may be assumed that and drive 5 straight reciprocating motion of cutter primary, It carries out once cutting ticket.When knife rest 3 is mobile to substrate 1, two elastic cushion blocks 4 are first pressed on page 91, and page 91 connects with substrate 1 Touching, knife rest 3 and cutter 5 continue to move down, a degree of compressive deformation of elastic cushion block generation (such as: 0.5mm~ 1.5mm), the blade of cutter enters in straight trough and cuts off page (page of cutting is required printed ticket)；Then knife Frame moves upwards, and cutter and elastic cushion block reset, and completes once to cut ticket.

By above-mentioned analysis it is found that in the cutter of receipt printing machine provided by the utility model, crank, connecting rod, cross bar, Guide rod and substrate form slider-crank mechanism, and the rotation of motor is allowed to drive guide rod, knife rest linear motion.On knife rest Elastic cushion block plays the role of platen, and the cutter on knife rest then cuts off page.The cutter of the receipt printing machine is tied on the whole Structure is compact, and it is small to be applied to occupied installation space in receipt printing machine, will not obviously increase the overall dimensions of receipt printing machine, and energy Enough realize automatically cuts off printed ticket, kills the hostage without manually going every time, simplifies operation.

It is understood that for those of ordinary skills, can with technical solution according to the present utility model and The design of its utility model is subject to equivalent substitution or change, and all these changes or replacement all should belong to the protection of the utility model Range.
