Description

Technical Field

[0001] The utility model relates to the field of printers, in particular to a quick-detachable printer. Background Art

[0002] Thermal transfer printing is a printing technology that transfers the toner coating on a carbon ribbon to paper or other types of materials through a print head. During the printing process, the carbon ribbon is transported by a motor, and the print head moves in the height direction under the control of a drive cylinder. When the print head heats and presses the carbon ribbon against the molding belt, the toner in the heated area is printed onto the molding belt to form a printed pattern. Existing thermal transfer printers usually have two printing modes: continuous printing and intermittent printing. When in intermittent printing, the molding belt will stay in the area to be printed during the printing process, and after the print head presses the carbon ribbon against the molding belt, it will move to the left or right relative to the molding belt and peel the print head and the carbon ribbon off through rollers. However, existing printers are difficult to disassemble and assemble, requiring a lot of time and manpower, which not only increases maintenance costs, but also easily causes damage to the printer during the disassembly and assembly process, and cannot meet market demand.

[0026] The utility model discloses a quick-release printer, comprising a mounting frame 1, a cover plate 2, a rear cover 3, a printing assembly 4, a quick-release assembly and a carbon ribbon conveying assembly. The cover plate 2 is detachably arranged on one side of the mounting frame 1 through the quick-release assembly, thereby forming a housing cavity for accommodating the printing assembly 4. The printing assembly 4 is connected to the mounting frame 1 and moves in the housing cavity. The rear cover 3 is arranged on the other side of the mounting frame 1, thereby protecting the motor and the like arranged inside. The mounting frame 1 also includes a slide 11, which is arranged horizontally, and the printing assembly 4 can print on the molding belt passing through the slide 11. Since in this embodiment, the printing assembly 4 uses a thermal transfer print head for printing, it is necessary for the carbon ribbon conveying assembly to continuously convey new carbon ribbons to the printing area of ​​the print head. When the print head presses the carbon ribbon against the molding belt and heats it, the carbon powder on the carbon ribbon can be transferred to the molding belt by controlling the heated area to form a printing pattern.

[0027] The quick release assembly is arranged on one side of the slide 11 close to the cover plate 2, and includes a clamping member 51, a seesaw 52, ​​a button 55 and a reset spring 54. The seesaw 52 is an integrated structure, including a pivoting portion 521 extending toward the mounting frame 1 and hinged to the mounting frame 1, and a flipping portion 522 connected to the pivoting portion 521. The pivoting portion 521 is rotatably arranged on the slide 11 of the mounting frame 1. The two ends of the flipping portion 522 are the clamping end and the abutting end, respectively, and the distance between the abutting end and the pivoting portion 521 is greater than the distance between the clamping end and the pivoting portion 521, thereby reducing the thrust required for unlocking through the lever principle. A gap is left between the clamping end and the mounting frame 1. The flipping portion 522 is provided with a transverse slot 523, and a rod body of a limiter 53 is passed through the slot 523. A limiter head is provided at the outer end of the rod body, and the rod body is connected to the slide 11.

[0028] The clamping member 51 is fixedly arranged on the cover plate 2, and a clamping joint 511 corresponding to the clamping end is arranged at its end. Preferably, the clamping joint 511 is a conical structure, and its conical surface can gradually push the seesaw 52 open, and the bottom surface of the conical structure abuts against the clamping end to achieve locking. The button 55 is slidably arranged on the cover plate 2, and the abutting end of the seesaw 52 corresponds to the button 55, and the reset spring 54 pushes the abutting end of the seesaw 52 toward the button 55. An elastic member 56 is also sleeved on the button 55, and the elastic member 56 abuts against the cover plate 2.

[0029] During installation, when the cover plate 2 is covered on the mounting frame 1, the clamping member 51 moves with the cover plate 2, thereby driving the clamping joint 511 to approach the clamping end, and pushing the clamping end to make the seesaw 52 rotate counterclockwise. After the clamping joint 511 passes through the clamping end, the reset spring 54 pushes the seesaw 52 to reset and block the clamping joint 511 from retreating, so that the clamping joint 511 is clamped into the gap and the cover plate 2 is locked. When unlocking is required, the button 55 is pressed, and the button 55 pushes the abutting end of the seesaw 52 to make it rotate clockwise, thereby leaving enough space for the clamping joint 511 to pass through the clamping end and exit, and the cover plate 2 can be removed at this time.

[0030] The carbon ribbon conveying assembly includes a driving motor 61 arranged on the mounting frame 1, and the driving motor 61 drives the docking seat 62 to rotate. The cover plate 2 is provided with a rotating shaft 63, and a carbon ribbon installation sleeve 64 for installing a carbon ribbon roll is sleeved on the rotating shaft 63. The front end of the carbon ribbon installation sleeve 64 cooperates with the docking seat 62 through an abutment seat 65. The cooperation method is specifically that a positioning column 66 protruding from the abutment seat 65 is inserted on the carbon ribbon installation sleeve 64, and a positioning groove 621 cooperating with the positioning column 66 is opened on the docking seat 62. The rear end of the carbon ribbon installation sleeve 64 abuts against the rear cover through a tightening spring 67. A buffer sheet 68 is sandwiched between the abutment seat 65 of the docking seat 62 and the carbon ribbon installation sleeve 64. A plurality of spring buckles 641 are arranged along the circumference of the carbon ribbon installation sleeve 64 to clamp and fix the carbon ribbon roll.

[0031] Since two carbon ribbon rolls are usually required, one is used to reel in the discarded carbon ribbon that has been printed, and the other rotates with the pulling action of the carbon ribbon and releases the new carbon ribbon during the rotation. Therefore, there are two groups of carbon ribbon conveying components, and the two carbon ribbon rolls are respectively mounted on two carbon ribbon mounting sleeves 64. For the convenience of explanation, the carbon ribbon conveying components are respectively the first carbon ribbon conveying component and the second carbon ribbon conveying component. In the actual printing operation, the first carbon ribbon conveying component and the second carbon ribbon conveying component can be set to different rotation speeds respectively, so that the carbon ribbon is in a tensioned state.

[0032] During installation, due to the deviation in the angle between the positioning column 66 and the positioning groove 621, the positioning column 66 cannot be inserted into the positioning groove 621, and the driving motor 61 cannot drive the abutment seat 65 and the carbon ribbon installation sleeve 64 to rotate through the docking seat 62. Therefore, when the cover plate 2 is locked on the mounting frame 1, the abutment seat 65 will be lifted up by the positioning column 66, and the carbon ribbon installation sleeve 64 will retreat to compress the spring. When starting up, it is necessary to start the driving motors 61 of the first carbon ribbon conveying assembly and the second carbon ribbon conveying assembly at the same time, so that the two driving motors 61 continue to rotate in the same direction within a preset time. During idling, the docking seat 62 will rotate to an angle that matches the positioning column 66. At this time, the spring pushes the carbon ribbon installation sleeve 64 to move, so that the positioning column 66 is inserted into the positioning groove 621, so that the carbon ribbon installation sleeve 64 can rotate with the docking seat 62 to complete the docking. Afterwards, the two driving motors 61 continue to rotate in the opposite direction within the preset time, so that the carbon ribbon returns to the initial state to avoid wasting the carbon ribbon. In subsequent printing operations, the pressing spring 67 can provide a thrust to the ribbon installation sleeve 64 to ensure that the positioning post 66 does not separate from the positioning slot 621 .

[0033] In order to limit the relative position of the cover plate 2 and the mounting frame 1, at least two guide components are also included, and the guide component includes a guide sleeve 71 and a guide column 72 slidably inserted in the guide sleeve 71, the guide sleeve 71 is connected to the mounting frame 1, and the guide column 72 is connected to the cover plate 2. When disassembling, the cover plate 2 can slide along the axial direction of the guide component. The guide column 72 is also sleeved with a steering roller 73, and the steering roller 73 is used to wind the carbon ribbon, thereby reducing the wear of the carbon ribbon. Specifically, the carbon ribbon is conveyed from the carbon ribbon roll, bypasses a steering roller 73, and is then conveyed to the printing component 4. After printing, it bypasses another steering roller 73 and is recovered by another carbon ribbon roll.

[0034] The quick-detachable printer described in the utility model can realize quick disassembly and assembly, thereby facilitating maintenance of the interior of the accommodating cavity, saving labor costs and time required for maintenance.
