Embodiment Construction
[0039] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0040] figure 2 It is a structural schematic diagram of the closing device between the printing head and the printing roller in the present invention. see figure 2 , the closure device of the present invention comprises:
[0041] Two movable connecting rods 201 and 202 with the same structural size and arranged symmetrically on both lateral sides of the print head 200 and the printing roller 290;
[0042] The movable connecting rod 201 is taken as an example below to describe the movable connecting rod in detail. The movable connecting rod 202 and the movable connecting rod 201 have the same symmetrical structure. Such as figure 2 As shown, the movable link 201 includes a first rod 210 and a second rod 220, the first end 211 of the first rod 210 and the first end 221 of the second rod 220 are hinged by a hinge mechanism 230, an...

The invention discloses a closing device between a printing head and a printing roller and a printer. The closing device comprises two movable connection rods which are symmetrically arranged on the two sides of the printing head and the two sides of the printing roller in the transverse direction, and the structure and the size of the two movable connection rods are the same. Each movable connection rod comprises a first rod body and a second rod body, the first end of the first rod body is hinged to the first end of the second rod body through a hinged mechanism, the second end of the first rod body is hinged to the transverse outer end of the printing head, and the second end of the second rod body is hinged to the transverse outer end of the printing roller. The printing head is transversely parallel to the printing roller. The closing device has a first state and a second state, and the first state is different from the second state; when the closing device is in the first state, the printing head and the printing roller are parallelly pressed together; and when the closing device is in the second state, the printing head and the printing roller are separated from each other. By means of the closing device between the printing head and the printing roller and the printer, the printing quality can be improved.
Description
technical field [0001] The present application relates to the technical field of printers, in particular to a closing device between a print head and a printing roller and a corresponding printer. Background technique [0002] At present, thermal induction printers have been widely used in various point of sales (POS) to print consumption receipts, such as retail, financial, hotel, medical and other service industries. Thermal induction printers generally use paper rolls for printing. The paper roll is placed on the printing roller, and there is a closing device between the printing head and the printing roller. When the paper roll is installed, the closing device is closed, and the printing head is in contact with the printing paper roll, so that the content can be printed on the paper roll . [0003] In order to allow the user to replace the new paper roll conveniently when the paper roll is about to run out, it is necessary to pull the closing device to separate the pri...
