Description

Technical Field

[0001] The present invention belongs to the technical field of paperless printers, and in particular relates to a high-speed and stable paperless printer. Background Art

[0002] A printer is one of the output devices of a computer, used to print the results of computer processing on relevant media. There are three indicators to measure the quality of a printer: print resolution, print speed and noise. There are many types of printers. According to whether the printing element has an impact on the paper, they are divided into impact printers and non-impact printers. According to the structure of printed characters, they are divided into full-width character printers and dot matrix character printers. According to the way a line of characters is formed on the paper, they are divided into serial printers and line printers. According to the technology used, they are divided into cylindrical, spherical, inkjet, thermal, laser, electrostatic, magnetic, light-emitting diode and other printers.

[0003] Common paperless printers connect directly to an external paper storage area via a paper feed channel, omitting the traditional large-capacity paper storage structure. Paper is drawn from the external paper stack into the printer's internal print area piece by piece through friction and the rotation of the paper feed rollers for printing. During this process, the paper is prone to deviation as it moves, and conventional paper retaining mechanisms can easily create resistance, resulting in unsmooth paper movement and an inability to accommodate paper of varying sizes. To address this issue, we propose a high-speed and stable paperless printer. Summary of the Invention

[0004] The object of the present invention is to provide a high-speed and stable paperless printer to solve the problems raised in the above background technology.

[0005] In view of this, the present invention provides a high-speed and stable paperless printer, comprising:

[0006] A housing, wherein an inner cavity is defined within the housing, a body is fixedly mounted within the inner cavity, a guide plate is fixedly mounted on the top of the body, a plurality of first support blocks and a plurality of first gap sensors are fixedly mounted on the top of the guide plate, a printing assembly is rotatably mounted on the guide plate, a plurality of second support blocks and a plurality of second gap sensors are fixedly mounted on the bottom of the printing assembly, and a lock buckle is symmetrically fixedly mounted on the bottom of the printing assembly;

[0007] Two paper stoppers, the two paper stoppers are symmetrically arranged on the top of the guide plate and located on one side of the plurality of support blocks, the support plates are fixedly mounted on opposite sides of the two paper stoppers, the tops of the support plates are fixedly mounted with a plurality of support blocks three, an external paper bin is provided on one side of the housing, label paper is provided on the external paper bin, and one end of the label paper passes between the guide plate and the printing assembly;

[0008] A driving assembly, the driving assembly being located on the guide plate and being used to drive the two paper stoppers toward or away from each other;

[0009] A power assembly is located on the guide plate and is used to drive the label paper to move.

[0010] In this technical solution, when in use, personnel can first drive the two paper stops to move closer to each other through the driving assembly according to the width of the label paper. The two paper stops moving closer to each other will drive the two support plates to move closer to each other until the opposite sides of the two paper stops are against the two sides of the label paper. At this time, the two paper stops can limit the label paper, ensuring that the two paper stops can limit the label paper of different widths and ensure that the paper stops will not deviate. At the same time, the paper stops cancel the upper and lower paper stops and only use the left and right method to stop the paper, so that the label paper will not get stuck during the movement;

[0011] At the same time, the power component will drive the label paper to move stably. With the cooperation of several first gap sensors, several second gap sensors and paper output sensors, the label paper detection accuracy and sensitivity can be improved, so that it can more accurately detect the existence, position and status of the label paper, and timely feedback the label paper information to the printer control system, so as to accurately control the paper feeding process, realize all-round detection of the machine body, and prevent paper feeding problems caused by sensor failure or detection blind spots.

[0012] In the above technical solution, further, the driving component includes:

[0013] A sliding groove is provided at the top of the guide plate and is located below the two paper stop blocks. Sliding blocks are symmetrically installed in the sliding groove for sliding.

A bidirectional threaded rod is rotatably installed in the sliding groove. One end of the bidirectional threaded rod passes through the two sliding blocks. A motor is fixedly installed in the sliding groove and on one side of the bidirectional threaded rod. The output end of the motor is coaxially connected to the bidirectional threaded rod.

[0014] In this technical solution, the motor is started, and the output shaft of the motor will drive the bidirectional threaded rod to rotate. Under the action of the thread, the rotation of the bidirectional threaded rod will drive the two sliding blocks closer to each other, and the two sliding blocks closer to each other will drive the two paper stop blocks closer to each other, and the two paper stop blocks closer to each other will drive the two support plates closer to each other until the opposite sides of the two paper stop blocks are against the two sides of the label paper. At this time, the two paper stop blocks can limit the label paper, ensuring that the two paper stop blocks can limit label papers of different widths, ensuring that the paper stop blocks will not deviate, and at the same time, the paper stop blocks cancel the upper and lower paper stops, and only use the left and right method to stop the paper, so that the label paper will not get stuck during the movement.

[0017] In the above technical solution, further, the power assembly includes:

[0018] A rotating groove is provided at the top of the guide plate and is located on the other side of one of the support blocks. A pickup wheel is rotatably installed in the rotating groove. A gear is fixedly installed at one end of the pickup wheel. Two limit rods are rotatably installed in the rotating groove, and the bottoms of the two limit rods are both against the pickup wheel. A paper discharge sensor is fixedly installed at the top of the guide plate and on one side of the pickup wheel.

[0019] In this technical solution, the transmission mechanism inside the machine body will drive the gear to rotate, and the rotation of the gear will drive the paper pickup wheel to rotate. Under the action of the rebound force of several springs, several springs will squeeze the lower pressure plate, and the lower pressure plate will squeeze the label paper, so that the bottom of the label paper will always be in contact with the top of the paper pickup wheel, ensuring that the rotation of the paper pickup wheel can drive the label paper to move stably.

[0020] In the above technical solution, further, the top of the pickup wheel contacts the bottom of the label paper, and the limiting rod is engaged with the rotating groove.

The bottom ends of the several springs are fixedly installed with the same lower pressure plate. The top of the lower pressure plate and the anti-slip rods are fixedly installed in the several springs respectively. The bottom of the lower pressure plate is against the top of the paper pickup wheel.

[0025] In the above technical solution, further, the cross section of the sliding block is a T-shaped structure, the cross section of the sliding groove is a T-shaped structure, and the sliding block is tightly welded to the paper stop block.

[0026] In this technical solution, it is ensured that the sliding block will not fall off from the sliding groove, and the structural stability of the sliding block and the paper stop block is guaranteed.
