Description

Technical Field

[0001] The utility model relates to the field of printers, in particular to an inkjet printer cutting device and an inkjet printer. Background Art

[0002] After the printer has finished printing the print medium, it needs to cut the currently completed part. Currently, the printing and cutting work is mainly completed by a dedicated cutter. The cutter is a special equipment with a bracket, a cutter and a drive mechanism. Large-sized cutters will also be designed with a roller system that matches the printer, resulting in the printer taking up a lot of space when used with the cutter. However, the width of the printer is usually large and occupies a large space. The space for placing the cutter is very limited and it is easy to exceed the scope of the land. Therefore, most of the cutting work will transfer the fabric to a special area and then cut it with a cutter, which is very cumbersome.

[0003] In order to simplify the structure of the printer cutting device, the utility model patent with the authorization announcement number CN220180414U discloses a printer cutting mechanism and a printer with integrated cutting function, including a cutter, a pressure wheel, a bracket and a lifting drive mechanism; the lifting drive mechanism is installed on the bracket, and the cutter and the pressure wheel are installed on the movable end of the lifting drive mechanism; the pressure wheel is located on the inner side or the outer side or both sides of the cutter; the lower edge of the cutter is lower than or equal to the lower wheel surface of the pressure wheel. The printer cutting mechanism and the printer with integrated cutting function have the advantages of stable cutting action and can be integrated into the printer. However, when the device cuts the printing medium, a single pressure wheel is used for pressing, which will cause the other side of the cut to be wrinkled because it cannot be effectively fixed, and the single pressure wheel is directly attached to the arc guide plate, which will cause the pressure wheel and the arc guide plate to not fit, and the pressure wheel will vibrate and deviate due to the lack of guide rail constraints when walking. Utility Model Content

[0004] In order to ensure that the printing media on both sides of the cutting seam can be well pressed when cutting the printing media to prevent wrinkles, and to ensure that the pressing wheel has adaptive adjustment ability and walking guide when walking to prevent it from deviating, the technical solution adopted by the utility model is: an inkjet printer cutting device, including a cutter, a pressing wheel assembly, an electromagnet mounting plate and a lifting drive mechanism;

[0005] The lifting drive mechanism is mounted on the electromagnet mounting plate, and the cutter and pressure wheel assembly is mounted on the movable end of the lifting drive mechanism;

[0006] The pressure wheel assembly includes a mounting seat, a pressure wheel mounting frame and a pair of pressure wheels. The mounting seat is fixed on the movable end of the lifting drive mechanism. The pressure wheel mounting frame is hingedly connected to one side of the mounting seat in a form of high inside and low outside. The pair of pressure wheels are rollingly mounted on the bottom of the pressure wheel mounting frame, and the pair of pressure wheels are located on both sides of the cutter.

[0007] Based on the above, in order to limit the tilt angle of the pressure roller mounting frame, a stop pin for limiting the tilt angle of the pressure roller mounting frame is provided at the outer end of the mounting seat.

[0008] Based on the above, in order to facilitate installation and not interfere with cutting by the cutter, the pressure wheel mounting frame is an inverted U-shaped mounting frame, and the top of the inverted U-shaped mounting frame is hinged to the mounting seat.

[0009] Based on the above, the rolling direction of the pair of pressing wheels is the same as the moving direction of the cutter.

[0010] Based on the above, the cutter is perpendicular to the mounting seat.

[0011] Based on the above, in order to facilitate automatic control, the lifting drive mechanism includes an electromagnet coil, an electromagnet push rod, a guide block, a slider and a cutting connection plate;

[0012] The electromagnet coil is mounted on the top of the electromagnet mounting plate, the guide block is mounted on the bottom of the electromagnet mounting plate, the cutting connecting plate is connected to the slider, and the cutter and the mounting seat are arranged on the cutting connecting plate;

[0013] The guide block is provided with a slide block guide groove, and the electromagnet coil drives the slide block to slide up and down through the electromagnet push rod.

[0014] Based on the above, the cutter is in the shape of a triangle with a narrow bottom and a wide top.

[0015] Based on the above, in order to facilitate installation and realize bidirectional cutting, blades are provided on both lateral sides of the cutter.

[0016] The utility model also provides an inkjet printer, comprising a printing carriage, a printing platform and a printer body, wherein the printing carriage can reciprocate on the printer body, the printing platform is located below the traveling track of the printing carriage, a cutting groove is arranged on the printing platform, the above-mentioned inkjet printer cutting device is installed on one side of the printing carriage, the position of the cutter is opposite to the cutting groove, and a pair of the pressure wheels are inclined to cross the cutting groove.

[0017] Specifically, the printing platform is divided into a platform plate and an arc-shaped guide plate at the cutting groove, the platform plate is horizontally arranged, and the arc-shaped guide plate is arranged in an arc shape.

[0018] The present invention has substantial features and progress compared to the prior art. Specifically, the inkjet printer cutting device provided by the present invention has a certain degree of freedom and can be adaptively adjusted by designing the pressure wheel assembly so that when the printing medium is pressed and fixed, the two pressure wheels are tilted and hinged on the mounting seat through the pressure wheel mounting frame, so that the printing medium can be fully pressed during cutting, avoiding the problem that a single pressure wheel cannot roll and fit tightly with the arc guide plate. At the same time, one of the pressure wheels rolls and fits on the outer wall of the cutting groove, and moves with the outer wall of the cutting groove as a guide, avoiding the phenomenon of the pressure wheel moving without a reference, and ensuring that the pressure wheel can be guided when moving to prevent it from going off track. The other pressure wheel rolls and fits on the other side of the cutting groove, so that when the printing medium is cut, the printing medium on both sides of the cutting seam can be well pressed to prevent wrinkles, thereby improving the cutting accuracy.

[0019] Furthermore, the device tilts and hinges the two pressure wheels on the mounting base through a pressure wheel mounting frame. The lowest point of the device is the lower wheel surface of one of the pressure wheels, and the lower edge of the cutter does not need to be set lower than the lower wheel surface, thereby avoiding the cutter hanging in the air and injuring people, thereby improving safety.

[0020] Furthermore, the device integrates the cutting function directly on the printer, specifically on one side of the moving printing carriage. When cutting is required, the cutter is dropped, the pressure wheel presses the printing medium to prevent the edge from warping after cutting, and the cutter is used to cut the printing medium. As the printing carriage moves, the printing medium is directly cut off, avoiding the problem of introducing a separate cutting mechanism. Since the cutting movement is combined with the printing carriage and is consistent with the cutting requirements of the printing medium, a set of motion drive devices used for cutting is saved, the size of the equipment is greatly reduced, and costs are saved.

[0032] In this embodiment, in order to facilitate automatic control, the lifting drive mechanism includes an electromagnet coil 2, an electromagnet push rod 13, a guide block 4, a slide block 5 and a cutting connection plate 6.

[0033] The electromagnet coil 2 is mounted on the top of the electromagnet mounting plate 1, and the guide block 4 is mounted on the lower part of the electromagnet mounting plate 1.

[0038] This embodiment provides a cutting device for an inkjet printer, which is different from Embodiment 1 mainly in that, in this embodiment: the cutter is perpendicular to the mounting seat, and the shape of the cutter is a triangle with a narrow bottom and a wide top.

[0039] Example 4

[0040] This embodiment provides a cutting device for an inkjet printer, which is different from Embodiment 1 mainly in that, in this embodiment: in order to facilitate installation and realize bidirectional cutting, blades are provided on both lateral sides of the cutter.

[0041] Example 5

[0042] This embodiment provides an inkjet printer, which is equipped with the inkjet printer cutting device described in any one of embodiments 1 to 4.

[0043] Specifically, Figure 4 As shown, the inkjet printer includes a printing carriage, a printing platform and a printer body. The printing carriage can move back and forth on the printer body, the printing platform is located below the traveling track of the printing carriage, a cutting groove 14 is provided on the printing platform, and the above-mentioned inkjet printer cutting device is installed on one side of the printing carriage.

[0044] The position of the cutter 7 is directly opposite to the cutting groove 14, and a pair of the pressing wheels are inclined across the cutting groove. One of the pressing wheels rolls against the outer side wall of the cutting groove, and the other pressing wheel rolls against the other side of the cutting groove.

[0046] For the specific installation position and structure, refer to the installation position and structure of the printer with integrated cutting function in the utility model patent with authorization announcement number CN220180414U.

[0047] Specifically, the working process of the inkjet printer cutting device is as follows:

[0048] Under normal printing conditions, the electromagnet coil is controlled to lift the cutter and pressure wheel assembly through the electromagnet push rod so that the cutter and pressure wheel assembly are not in contact with the printing medium. The printing carriage prints patterns on the surface of the printing medium during reciprocating horizontal motion.

[0049] When cutting is required, the electromagnetic coil is controlled to move the cutter and pressure wheel assembly downward through the electromagnetic push rod. The pressure wheel moves to the extent of pressing the printing medium, and cooperates with the printing platform, and the cutter extends into the cutting groove, with the vertical side corresponding to the edge of the printing medium. Then the printing carriage is driven to move horizontally, and the cutter cuts the printing medium to achieve the cutting function.

[0050] After cutting is completed, the electromagnet coil is controlled to lift the cutter and pressure wheel assembly again through the electromagnet push rod, without affecting the normal printing work of the printing carriage.

[0051] When the pressure wheel assembly is pressing and fixing the printing medium, one of the pressure wheels rolls and fits against the side wall of the cutting groove, and moves with the side wall of the cutting groove as a guide, avoiding the phenomenon of no reference when the pressure wheel moves. At the same time, the other pressure wheel rolls and fits against the cutting groove, so that when the printing medium is cut, the printing medium on both sides of the cutting seam can be well pressed to prevent wrinkles, and the two pressure wheels are tilted and hinged on the mounting seat through the pressure wheel mounting frame, with a certain degree of freedom and can be adaptively adjusted.

[0052] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it.
