Description

Technical Field

[0001] The utility model relates to the technical field of printers, in particular to a paper reel for an industrial printer. Background Art

[0002] The printer was invented by John Watt and Dave Donald. It is a device that prints computer calculation results or intermediate results on paper in the form of numbers, letters, symbols and graphics that humans can recognize according to a prescribed format. Printers are developing in the direction of being light, thin, short, small, low power consumption, high speed and intelligent. In industrial production, the paper roll in the printer is usually supported and fixed by the printer paper reel.

[0003] However, in the prior art, paper is usually fed by directly sleeved on the outer surface of the paper roll shaft, which makes it difficult to install and fix paper rolls of different widths, and the scope of application is small. In addition, during the feeding process, the paper roll is prone to rotate and shake up and down on the paper roll shaft, making it difficult for the paper to enter the printer smoothly, which will affect the printing effect of the paper.

DETAILED DESCRIPTION

[0024] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0025] Reference Figure 1-4 An industrial printer paper reel includes a base 1, a square groove 101 is formed on the base 1, a pair of assembly blocks 102 are arranged on the base 1, and a mounting hole 1021 is formed on each of the pair of assembly blocks 102. Through the assembly blocks 102 and the mounting holes 1021, the paper reel can be conveniently installed at a suitable position on the printer.

[0026] A screw rod 2 is rotatably installed in the square groove 101, and opposite threads are symmetrically arranged on the outer surface of the screw rod 2. One end of the screw rod 2 passes through the square groove 101 to the outside of the base 1, and a turntable 201 is installed on one end of the screw rod 2. The outer surface thread of the screw rod 2 is matched with a pair of sliding blocks 3, and the pair of sliding blocks 3 are matched with the square groove 101. Vertical plates 4 are vertically installed on the top of the pair of sliding blocks 3.

[0027] A pair of fixing rings 401 are provided on the bottom surfaces of a pair of vertical plates 4, a pair of cross bars 5 are provided on the base 1, a pair of fixing rings 401 are matched on the outer surfaces of the cross bars 5, the vertical plates 4 are located between the pair of cross bars 5, a pair of brackets are symmetrically provided on the base 1, and a cross bar 5 is installed between the tops of the pair of brackets, and through the cross bars 5 and the fixing rings 401, the pair of vertical plates 4 can be stably moved horizontally toward each other.

[0028] When fixing the paper roll, the turntable 201 is rotated, and the turntable 201 drives the screw 2 to rotate in the square groove 101. The rotation of the screw 2 makes a pair of sliding blocks 3 slide toward each other in the square groove 101. The sliding of the pair of sliding blocks 3 drives a pair of vertical plates 4 to move horizontally toward each other, so that the three elastic fixing components 7 on the pair of shafts 6 are respectively stuck in the inner walls of the two ends of the paper roll drum until the two ends of the paper roll contact with one side surface of a pair of limit rings 8, and then the rotation of the turntable 201 is stopped, so that paper rolls of different widths can be installed and fixed, which effectively improves the application range of the paper reel, is convenient for installing and disassembling the paper roll, improves printing efficiency, and can keep the paper roll in the center position to avoid paper skewing during the feeding process, effectively improve the printing quality, and reduce the defective rate of the printed product.

[0029] A pair of vertical plates 4 are rotatably mounted with shafts 6, one end of which is embedded with three elastic fixing components 7, and the outer surface of one end of which is interference-fitted with a limiting ring 8, which can limit the position of the paper roll and ensure that the paper roll can remain in the center position.

[0030] The elastic fixing assembly 7 includes an arc-shaped plate 701 and a fixing block 702. One end of the shaft 6 is provided with three fixing grooves 601. The three fixing blocks 702 are respectively arranged in the three fixing grooves 601. The inner ring of the limiting ring 8 is provided with three clamping grooves 801. One end of the three fixing blocks 702 is respectively matched with the three clamping grooves 801. The fixing block 702 is provided with a receiving groove 7021. The receiving groove 7021 is provided with a fixing rod 703. The surface of the fixing rod 703 The gap is matched with a spring 704 and a movable sleeve 705, and a buckle 7051 is provided on the movable sleeve 705. The buckle 7051 cooperates with the accommodating groove 7021. One end of the arc plate 701 is connected to the buckle 7051. A plurality of anti-skid convex particles 7011 are provided on the arc plate 701. The anti-skid convex particles 7011 are elastic rubber blocks. The friction between the arc plate 701 and the inner wall surface of the reel can be increased through the anti-skid convex particles 7011 to prevent the reel from rolling during feeding.

[0031] In the process of fixing the paper roll on the paper roll shaft, the paper roll is horizontally placed in the plane between the pair of shafts 6, and then the pair of vertical plates 4 move toward each other, so that the inner walls of the two ends of the roll drum of the paper roll are respectively in contact with the three elastic fixing components 7 on the pair of shafts 6, and the inner wall surface of the roll drum is in contact with the outer surface of the arc plate 701 on the elastic fixing component 7 and generates an extrusion force perpendicular to the arc plate 701. After the arc plate 701 is subjected to the extrusion force, it is transmitted to the movable sleeve 705 through the buckle 7051, and the movable sleeve 705 slides on the surface of the fixed rod 703 and squeezes the spring 704. After being squeezed, the spring 704 contracts, and the buckle 7051 on the fixed block 702 The arc plate 701 slides in the accommodating groove 7021, so that the arc plate 701 enters the inner wall of one end of the roll, and through the resilience of the spring 704 and the anti-slip convex particles 7011 set on the surface of the arc plate 701, the outer surface of the arc plate 701 is firmly fitted with the inner wall surface of the roll, so that the three arc plates 701 in the three elastic fixing components 7 on the pair of shafts 6 are respectively fitted with the inner wall surfaces at both ends of the roll, and the paper roll is stably fixed between the pair of elastic fixing components 7, so that the paper roll can be stably fixed, and the paper roll can be prevented from rotating and shaking up and down following the rotation of the shaft 6 during the feeding process, ensuring that the paper can enter the printer smoothly and the printing effect of the paper is guaranteed.
