Description

Technical Field

[0001] This invention relates to printer testing technology, and more particularly to an aging tester for testing printer mechanisms. Background Technology

[0002] In the printer testing process, most existing aging tests use bare printer cores in conjunction with motherboards and computers for online testing. However, due to the large number of test items in the test room, there is often a shortage of test computers, which delays the testing. In addition, there are certain safety hazards because the test equipment is unattended during non-working hours. Therefore, all existing tests are conducted during working hours (8 hours).

[0003] Therefore, there is an urgent need to improve existing testing equipment to ensure stable testing results and enable continuous 24-hour (offline) testing without electrical safety hazards, thereby improving testing efficiency. Furthermore, current methods for testing printer mechanism aging rely on simple fixtures with limited functionality. These fixtures cannot automatically detect motor temperature, monitor ambient temperature, adjust paper cutting speed, detect paper output speed, or automatically record all aging data. Additionally, the normal operating method for printer mechanisms is head-up, resulting in paper output that is difficult to collect. All these factors contribute to the inconvenience and low efficiency of current printer mechanism testing. Summary of the Invention

[0004] This invention provides an aging test machine for testing printer mechanisms. It can perform offline continuous testing and obtain the required data under conditions without electrical safety hazards. It also facilitates the replacement of the mechanism and printing paper, and the collection of waste paper, effectively improving testing efficiency.

[0005] The technical solution adopted by this invention to solve its technical problem is:

[0006] An aging test machine for testing printer mechanism components includes:

[0007] The base plate is used for supporting and fixing the entire machine.

[0008] A paper roll holder is symmetrically placed on both sides of one end of the base plate and is used for rotating and installing a removable and replaceable paper roll.

[0009] The paper roll upper limit mechanism is slidably installed on one side of the paper roll fixing frame, and automatically presses against the top side of the paper roll after the paper roll is dispensed.

[0010] The paper roll lower limit mechanism is slidably installed on the other side of the paper roll fixing frame by being pulled down by a gravity component, and automatically presses against the lower side of the paper roll after the paper roll is discharged to prevent the paper belt from deviating during the paper feeding process.

[0011] A paper roll linear speed testing mechanism is installed on the lower limit mechanism of the paper roll and presses against the lower side of the paper roll to test the paper roll output speed.

[0012] The paper output limiting mechanism is located near the roll paper fixing frame and deflects and guides the paper tape output from the roll paper.

[0013] The mechanism flipping and fixing mechanism is located on the upper side of the paper tape behind the paper output limiting mechanism, and is used to flip and contact the lower paper tape after the mechanism is installed and fixed.

[0014] The rubber roller lifting mechanism is located directly opposite the lower side of the core on the core flipping and fixing mechanism, and drives the top rubber roller to lift and bring the paper tape into contact with the core.

[0015] The electrical control box is installed at the other end of the base plate relative to the paper roll fixing frame and is used for testing and control of the whole machine.

[0016] Preferably, a side control box for placing an external electrical control board for measurement and control is also provided on the side of the base plate.

[0017] Preferably, the movement flipping and fixing mechanism includes a fixed frame, a flipping frame for fixing the movement to be tested on the lower side, and two sets of symmetrically arranged buckle assemblies. The flipping frame is hinged to one end of the fixed frame by two sets of hinges, and the two sets of buckle assemblies are symmetrically arranged at the other end of the fixed frame for locking the two sides of the flipping frame from both sides.

[0018] Preferably, the paper roll upper limit mechanism includes two sets of sliding guide wheels and a self-weight pressing frame. The self-weight pressing frame is installed on one side of the paper roll fixing frame by sliding up and down through the two sets of sliding guide wheels and contacts the uppermost side of the paper roll by its own weight. Correspondingly, the paper roll fixing frame has two grooves on one side that cooperate with the two sets of sliding guide wheels respectively.

[0019] Preferably, the lower limiting mechanism of the paper roll includes a gravity component, a lower pressure roller and a lower roller frame for pressing the lower side of the paper roll from the top. The lower pressure roller is rotatably mounted on the lower roller frame. The gravity component is linearly slidably mounted on a first linear guide rail on the outer edge of the other side of the paper roll fixing frame. A second linear guide rail is provided on the inner edge of the other side of the paper roll fixing frame for linearly sliding the lower roller frame from the top. A steering wheel is also provided at the top of the other side of the paper roll fixing frame. A traction rope is provided between the gravity component and the lower roller frame, which is slidably suspended at the top and mounted on the steering wheel. This rope is used to pull the lower roller frame and the lower pressure roller by the weight of the gravity component, so that the lower pressure roller always presses against the bottom of the paper roll. The paper roll linear speed testing mechanism is mounted on the lower roller frame of the lower limiting mechanism of the paper roll.

[0020] Preferably, the paper roll linear speed testing mechanism includes an encoder mounted on the lower roller frame, the encoder pressing against the underside of the paper roll and rotating coaxially with the lower pressure roller.

[0021] Preferably, the paper output limiting mechanism includes a guide roller and a guide roller frame. The guide roller is rotatably mounted on the guide roller frame and deflects the paper roll at a certain angle before outputting it.

[0022] Preferably, two limiting wheels for limiting the deviation of the paper tape are symmetrically provided on both sides of the guide roller.

[0023] Preferably, the rubber roller lifting mechanism includes a rubber roller and two electric push rods disposed at both ends of the rubber roller. The rubber roller is horizontally positioned under the paper roll and rotatably mounted on the top of the two electric push rods. The two electric push rods synchronously lift and push the rubber roller to drive the paper roll to contact the paper roll with the underside of the core mechanism which is flipped and fixed by the core mechanism flipping and fixing mechanism.

[0024] The beneficial effects of this invention are:

[0025] In this aging tester, the core is fixed by a core flipping and fixing mechanism and flipped to the underside of the frame. The corresponding rubber roller lifting mechanism lifts and pushes the paper roll up to contact the core, making it easy for waste paper from printing tests to flow out and be collected downwards. It can achieve offline continuous testing under conditions without electrical safety hazards, which can effectively improve testing efficiency and realize fully automatic testing without human intervention.

[0026] Meanwhile, the movement flipping and fixing mechanism uses a snap-fit ​​assembly to lock the flipping frame, which effectively facilitates the disassembly, installation and replacement of the movement, enabling the replacement and testing of different types of movements and improving the applicability of the equipment.

[0027] In addition, as the test paper roll decreases during the printing process, the upper limit mechanism of the paper roll automatically slides down by its own weight and always automatically contacts the top side of the paper roll. The lower limit mechanism of the paper roll pulls the encoder and the lower pressure roller on the lower roller frame to contact the lower side of the paper roll through the gravity component, which effectively prevents the paper belt from running off track during the paper feeding process. At the same time, the encoder rotates synchronously with the paper roll to test the linear speed of the paper roll output, which is accurate and reliable and realizes full-process automated monitoring.

[0037] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0038] In the description of this invention, it should be understood that the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature.

[0039] It should be noted that similar reference numerals and letters in the following figures indicate similar items.

The paper roll upper limit mechanism 3 includes two sets of sliding guide wheels 30 and a self-weight contact frame 31. The self-weight contact frame 31, which is horizontally arranged coaxially with the paper roll 10, is installed on one side of the paper roll fixing frame 2 by sliding up and down through two sets of sliding guide wheels and contacts the uppermost side of the paper roll 10 by its own weight.
