The present utility model will be described in detail below with reference to the accompanying drawings and examples.

The utility model provides a printer with an electronic anti-collision function, as shown in figures 1-5, comprising: a cross beam 1, a controller (not labeled in the drawings); a printing component 2 and a driving component 3 for driving the printing component 2 to reciprocate on the cross beam 1 are arranged on the cross beam 1 in a sliding manner; the driving end of the driving assembly 3 is in transmission connection with the printing assembly 2; the electronic anti-collision assemblies 4 are arranged at the two ends of the reciprocating movement of the printing assembly 2; the printing component 2 and the driving component 3 are electrically connected with the controller; the electronic collision avoidance assembly 4 comprises: the protective shell 41, a detection plate 42 for detecting the flatness of the printing stock and performing a leveling function to a certain extent, and a touch switch 43; the upper end of the detection plate 42 is hinged with the protective shell 41, and the lower end of the detection plate is abutted with the triggering end of the touch switch 43; the touch switch 43 is fixedly installed in the protective shell 41 and is electrically connected with the controller; the protective shell 41 is fixedly connected with the printing component 2.

In this embodiment, the printer further includes a conventional feeding assembly, an adsorption assembly, and a receiving assembly, where the foregoing assemblies are irrelevant to solving the technical problem and are not specifically described herein; the controller in the embodiment is a PLC, and the printing component 2 is in sliding connection with the cross beam 1 through a linear guide rail; the driving component 3 is arranged on the cross beam 1, and drives the printing component 2 to reciprocate along the length direction of the cross beam 1 under the control of the controller; the electronic anti-collision assemblies 4 are respectively fixedly arranged at two ends (two ends in the reciprocating direction) of the printing assembly 2 through screws; as shown in fig. 5, the electronic anti-collision assembly 4 is composed of a protective shell 41, a detection plate 42 and a touch switch 43; the detection plate 42 is hinged with the protective shell 41 and forms a box-shaped structure, and the touch switch 43 is positioned inside the box-shaped structure and fixed on the protective shell 41 through a buckle; the detection plate 42 is abutted against the trigger end of the touch switch 43 under the action of gravity, when the protrusion of a printing stock is large, the detection plate 42 is abutted against the touch switch 43 to be switched into a conducting state, and the controller receives a signal to control the driving assembly 3 to move so as to stop sliding the printing assembly 2, so that the nozzle 24 is prevented from being collided with the inner wall of the printer to be damaged; when the printing stock is free of protrusions, wrinkles or only slightly protruding, the acting force of the detection plate 42 on the touch switch 43 cannot enable the touch switch 43 to switch on, and the detection plate 42 levels the micro-protruding portions of the printing stock, so that the printing stock protrusion resistance of the printer is improved. In addition, the touch switch 43 has lower material cost and lower requirement on air cleanliness compared with an infrared emission sensor.

As shown in fig. 2, for printing a printing object with a larger width, two printing assemblies 2 can be slidably arranged on the beam 1, and at this time, both printing assemblies 2 are driven by the same driving assembly 3.

Further, most of the printing stock is made of paper, and the physical strength is not high, so that the printing stock is easy to damage when rubbed or collided with the detection plate 42; thus, sensing plate 42 is made of a soft plastic and preferably a low coefficient of friction polytetrafluoroethylene material. To further reduce the friction or impact force of the sensing plate 42 against the substrate, the bottom of the sensing plate 42 is configured to be wavy (like a saw tooth as shown in fig. 5), and rounded at the peaks and valleys of the wavy shape.

Further, the printing assembly 2 includes: a lateral bottom plate 21 that slides in the horizontal direction; a vertical bracket 22 sliding in the vertical direction is slidably provided on the lateral bottom plate 21; a height adjusting member 23 for adjusting the horizontal height of the vertical support 22 is provided on the lateral bottom plate 21; a spray head 24 is arranged on the vertical support 22; the driving end of the height adjusting piece 23 is fixedly connected with the vertical bracket 22; the vertical support 22 is fixedly connected with the protective shell 41; the transverse bottom plate 21 is fixedly connected with the driving assembly 3; the spray head 24 is electrically connected to the controller.

Further, the height adjuster 23 includes: an adjusting lever 231, a driving rod 232, a driving base 233, and a height block 234; the adjusting rod 231 and the transmission rod 232 are both rotatably connected with the transmission base 233; the upper end of the transmission rod 232 is in meshed connection with the adjusting rod 231, and the lower end of the transmission rod is in threaded connection with the height block 234; the transmission base 233 is fixedly connected with the transverse base plate 21; the height block 234 is fixedly connected to the vertical support 22.

Further, the driving assembly 3 includes: the first driving wheel 31 and the second driving wheel which are respectively arranged at the two ends of the beam 1, the first driving belt 32, the second driving belt 33 and the driving motor 34; one end of the first transmission belt 32 is sleeved on the outer side of the first transmission wheel 31, and the other end of the first transmission belt is sleeved on the outer side of the second transmission wheel; one end of the second transmission belt 33 is sleeved on the outer side of the first transmission wheel 31, and the other end of the second transmission belt is sleeved on the output shaft of the driving motor 34; the first driving wheel 31, the second driving wheel and the driving motor 34 are fixedly arranged on the cross beam 1.
