Technical Field

[0001] This utility model patent relates to the technical field of barcode printer paper holders, and more specifically, to a centrally located barcode printer paper holder. Background Technology

[0002] A barcode printer is a professional printing device that uses self-adhesive labels, POSTEK labels, PET labels, hang tags, washable cloth, etc. as printing media, and can print barcodes (including serial numbers), text, symbols, and images in large quantities and quickly.

[0003] Currently, barcode printers use external paper holders to place and support the printing paper in order to avoid frequent paper changes. For example, the prior patent with authorization announcement number CN200940050Y discloses an external paper holder for printers, which includes a support frame consisting of a left support plate and a right support plate. A paper roll support rod is provided at the upper rear end of the support frame, and a paper guide roller is provided at the lower front end of the support frame. The paper guide roller is spring-tensioned and fixed in buffer grooves provided on the left and right support plates, and the other end of the spring is connected to the support plate.

[0004] In existing technologies, the printing paper is fixed by spring tension, which requires the installation of a locking device. This is not only costly, but also inconvenient for paper feeding and delivery. Furthermore, the locking device is prone to malfunction, affecting the lifespan of the paper holder.

[0021] Reference Figure 1-5 The image shown is a preferred embodiment of the present invention.

[0022] The paper holder for a centrally located barcode printer includes a main body 1 and a roller 2. The main body 1 includes two longitudinal frame plates 11 and a base 12. The two longitudinal frame plates 11 are arranged at intervals and vertically. The longitudinal frame plates 11 and the base 12 are assembled vertically. The base 12 is used to hold stacked printing paper. The two ends of the roller 2 are respectively assembled with the two longitudinal frame plates 11. The roller 2 is used to pass through and support the roll of printing paper. Along the direction from the two ends to the middle of the roller 2, the diameter of the roller 2 gradually decreases.

[0023] The aforementioned centrally located paper holder for barcode printers allows users to choose between stacked or rolled paper based on their printing needs, satisfying various printing requirements. Simultaneously, the combined action of the longitudinal frame plate 11 and the frame base 12 enhances the placement of the paper, providing protection and ensuring smooth printing operations. This simplifies the paper holder structure, reduces malfunctions, and extends the paper holder's lifespan. Furthermore, because the diameter of the rollers 2 gradually decreases from both ends to the middle, when rolled paper is placed, the tapered design ensures the rolled paper is centrally located, facilitating paper feeding and guaranteeing normal printing operations for the printer itself.

[0024] The roller frame 2 includes a roller body 21 and two roller fixing blocks 22. The roller body 21 is arranged in a gradually decreasing shape from both ends to the middle. The two ends of the roller body 21 are respectively connected to the two roller fixing blocks 22. The longitudinal frame plate 11 has a frame plate groove, and the roller fixing blocks 22 are embedded in the frame plate groove. This realizes the assembly of the roller frame 2 and the frame body 1.

[0025] The roller fixing blocks 22 are arranged in a rectangular shape; in this way, the rotation of the support roller 2 is restricted, and the rotation of the support roller 2 is prevented by the influence of the roll of printing paper, so as to ensure the stability of the support roller 2 and the support of the roll of printing paper.

[0026] The roller fixing block 22 has elastic blocks protruding on both sides. The elastic blocks are arranged in an arched arc shape and are elastically arranged. The elastic blocks are used to press against the groove wall of the support plate groove. In this way, under the action of the elastic blocks, the assembly stability of the roller fixing block 22 is enhanced, and the support stability of the roller 2 is also enhanced.

[0027] The roller body 21 includes two roller side sections and a roller middle section. The two ends of the roller middle section are respectively connected to the two roller side sections and are integrally formed. The roller side sections are arranged in a frustum shape. Along the direction towards the roller middle section, the diameter of the roller side sections gradually decreases. In this way, under the action of the roller side sections, the roll of printing paper tends to be arranged towards the roller middle section, so that the roll of printing paper is arranged in the center.

[0028] Furthermore, improving the coordination between the roller side section and the roll-to-roll printer enhances the feeding stability of the roll-to-roll printer.

[0029] The frame body 1 includes a frame baffle 15, which is arranged to abut against the frame base 12 vertically. The frame baffle 15 is assembled or separated from the ends of the two longitudinal frame plates 11. The frame baffle 15 extends longitudinally, and the frame baffle 15 and the two longitudinal frame plates 11 are arranged correspondingly along the outer periphery of the stacked printing paper.

[0030] In this way, the combined action of the baffle 15 and the two vertical baffles 11 protects the placed printing paper and positions the placed printer, facilitating the alignment of the stacked printing paper with the printer body and making printing operations easier.

[0031] Furthermore, by separating the ends of the baffle plate 15 from the two longitudinal frame plates 11, the paper feeding direction can be diversified to meet different paper feeding needs.

[0032] The top of the stand 12 has a frame 113, and the vertical frame plate 11 and the frame 113 are arranged to overlap each other. The frame 113 has a frame groove, and the bottom of the stacked printing paper is embedded in the frame groove. The frame 113 is equipped with a detector, and the detector is arranged corresponding to the frame groove. In this way, the amount of stacked printing paper is detected. When the amount of stacked printing paper is lower than the expected value, the detector sends a feedback signal to remind the user.

[0033] The monitor 4 can be an infrared monitor or a distance sensor.

[0034] The stand 12 includes four posts 111 and a base 112. The four posts 111 are arranged at the four corners, and the base 112 and the posts 111 are connected. The posts 111 extend in a direction away from the base 112. The posts 111 are used to suspend the base 112. The base 112 is used to place stacked printing paper. Under the action of the posts 111, the placement height of the stacked printing paper is increased, and the stacked printing paper is prevented from getting wet.

[0035] The inside of the support column 111 is provided with column suction blocks 3, which are magnetically arranged and whose bottoms are arranged to contact the outside; thus, the stability of the paper holder is improved.

[0036] The column suction block 3 can be a magnet. By attracting the external environment with the column suction block 3, the stability of the paper rack is improved, preventing the paper rack from shifting or moving, and ensuring the paper feeding effect of the paper rack.

[0037] The longitudinal frame plate 11 has a paper output tray 13, which is arranged correspondingly to the printer body, and the paper output tray 13 is arranged in a widening shape in the direction towards the printer body; in this way, the paper output tray 13 avoids obstructing the paper supply and facilitates the paper supply to the printer.

[0038] The longitudinal frame plate 11 has multiple perforated slots 14 arranged in a continuous manner; this helps to reduce the weight of the longitudinal frame plate 11 and makes it easier to carry the paper rack.

[0039] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
