Description

Technical Field

[0001] This utility model relates to the field of LED light curing technology, and in particular to a UVLED curing experimental device that simulates the paper feeding process of a printing press. Background Technology

[0002] Ultraviolet (UV) curing printers are widely used in the printing industry. After ink is applied to paper, it is placed in a UV lamp box for irradiation. Under the catalytic effect of UV light, the ink dries and cures rapidly. Large-scale printing equipment generally requires the use of special inks to improve curing efficiency, which are very expensive. However, using ordinary inks cannot achieve the same effect in a short time, and increasing the amount of UV irradiation can easily cause problems such as film and paper deformation and yellowing.

[0003] Chinese Patent CN208789256U discloses an online curing printing test machine, including an anilox roller, a doctor blade, a pneumatic blade head, a printing roller, a printing plate roller, a printing plate, and a printing substrate. It also includes a curing device and a control center. The curing device includes a lamp housing containing a substrate. Multiple UV mercury lamps are mounted on the substrate, forming a luminescent surface facing the printing roller. A connecting rod is located at the rear of the lamp housing and connected to a swing mechanism. A support column is located at the lower end of the swing mechanism. The control center controls the operation of the curing device. This device uses UV mercury lamps to irradiate the printing substrate for curing. The control center can adjust the direction and power of the UV mercury lamp irradiation to simulate the printing conditions of various printing press models. Simultaneously, a cooling pipe reduces the temperature of the UV mercury lamps, extending their lifespan.

[0004] However, the above technical solution has the following shortcomings: although the device can perform curing experiments, it cannot simulate the changes in paper tension during use, and therefore cannot determine the effect of paper tension on ink curing, which reduces the practicality of the device. Utility Model Content

[0005] The purpose of this invention is to address the problems existing in the background technology by proposing a UV LED curing experimental device that simulates the paper feeding process of a printing press. This device can not only adjust the lamp configuration but also control and regulate the paper tension, thereby gaining a better understanding of more factors affecting ink curing.

[0006] The present invention provides a UV LED curing experimental device for simulating the paper feeding operation of a printing press, comprising a base and a paper-fixing device. The base has a support block and a simulated machine body; the support block has a conveyor seat; the conveyor seat has a curing sample lamp; and the conveyor seat has a horizontally movable mounting base. The paper-fixing device includes a first and second upright on the mounting base, a unwinding roller rotatably connected to the first upright, a fixed cylinder rotatably connected to the second upright, a locking assembly on the fixed cylinder, and an adjustment mechanism on the mounting base. The adjustment mechanism includes two third uprights on the mounting base, a first threaded rod rotatably connected to one third upright, a threaded block threaded to the first threaded rod, a crossbar on the threaded block, a fixed base and a slider on the crossbar, an adjusting roller rotatably connected to the crossbar, and a first guide rod on the other third upright. The slider is slidably connected to the first guide rod.

[0007] Preferably, a light shield is provided on the simulator body, and the light shield is located outside the curing lamp.

[0008] Preferably, the top end of the first threaded rod passes through the third upright, and a handwheel is provided at the through end of the first threaded rod.

[0009] Preferably, the locking assembly includes a locking block fitted onto the fixed cylinder, a first magnet disposed on the locking block, and a second magnet disposed on the fixed cylinder; the first magnet and the second magnet are magnetically connected.

[0010] Preferably, the card block is provided with two symmetrically distributed interlocking plates, which are interlocked with the fixing cylinder.

[0011] Preferably, the conveyor seat is provided with a linear drive assembly, which includes a motor mounted on the conveyor seat, a second threaded rod rotatably connected to the conveyor seat, a second guide rod mounted on the conveyor seat, and a first moving block and a second moving block mounted on the mounting base.

[0012] Preferably, the motor and the second threaded rod are driven together, the second threaded rod and the first moving block are threaded together, and the second moving block is slidably connected to the second guide rod.

[0013] Compared with the prior art, the present invention has the following beneficial technical effects:

[0014] 1. This utility model avoids the high financial and time costs of installing the solidified solution on the printing press for testing by efficiently simulating the operation of a printing press. At the same time, this method flexibly adjusts the lamp configuration scheme to conduct rapid testing of multiple schemes, which has good practicality.

Detailed Implementation

[0023] Example 1

[0024] like Figures 1-6 As shown in the figure, the UV LED curing experimental device for simulating the paper feeding operation of a printing press proposed in this embodiment includes a base 1 and a paper fixing device; a support block 2 and a simulation body 5 are provided on the base 1, a conveyor seat 3 is provided on the support block 2, a curing sample lamp 6 is provided on the conveyor seat 3, a light shield 7 is provided on the simulation body 5, the light shield 7 is located outside the curing sample lamp 6, and a horizontally movable mounting seat 4 is provided on the conveyor seat 3. The number of lamps and the wavelength configuration of the curing sample lamp 6 are arranged according to the expected curing lamp scheme. It can be a single lamp with different rows and different wavelengths, or two or more lamps.

[0025] The paper-fixing device includes a first upright 8 and a second upright 10 mounted on the mounting base 4, a unwinding roller 9 rotatably connected to the first upright 8, a fixing cylinder 11 rotatably connected to the second upright 10, a locking assembly mounted on the fixing cylinder 11, and an adjustment mechanism mounted on the mounting base 4.

[0026] The adjustment mechanism includes two third uprights 16 mounted on the mounting base 4, a first threaded rod 17 rotatably connected to one side of the third upright 16, a threaded block 18 threadedly connected to the first threaded rod 17, a crossbar 21 mounted on the threaded block 18, a fixed seat 23 and a slider 22 mounted on the crossbar 21, an adjustment roller 24 rotatably connected to the crossbar 21, and a first guide rod 20 mounted on the other side of the third upright 16; the slider 22 is slidably connected to the first guide rod 20, the top end of the first threaded rod 17 passes through the third upright 16, and a handwheel 19 is provided at the through end of the first threaded rod 17; a pressure sensor (not shown) is provided inside the adjustment roller 24 to monitor the tension of the paper in real time.

[0027] The locking assembly includes a locking block 12 fitted onto a fixed cylinder 11, a first magnet 13 disposed on the locking block 12, and a second magnet 14 disposed on the fixed cylinder 11; the first magnet 13 and the second magnet 14 are magnetically connected, and two symmetrically distributed locking plates 15 are disposed on the locking block 12, and the locking plates 15 and the fixed cylinder 11 are locked together.

[0028] In this embodiment, before testing, the printed paper needs to be placed and fixed. The unwinding roller 9 is rotated to unwind the paper wound on it, and the paper is passed over the two adjusting rollers 24. Then, the end of the paper is placed on the second magnet 14 of the fixing cylinder 11, and the locking block 12 is embedded into the fixing cylinder 11, so that the first magnet 13 and the second magnet 14 are magnetically connected to complete the fixing operation of the paper. Then, the first threaded rod 17 is rotated by the handwheel 19, so that the first threaded rod 17 and the threaded block 18 are screwed together. Under the guidance of the slider 22 and the first guide rod 20, the cross frame 21 drives the fixing seat 23 to move vertically. The position of the fixing seat 23 is adjusted with the pressure sensor so that the signal value transmitted by the pressure sensor is the value of the design scheme. While adjusting the fixing seat 23, the unwinding roller 9 needs to be operated appropriately to avoid the paper being too tight or too loose. This realizes the simulation of paper tension, judges the influence of paper tension on ink curing, and improves the practicality of the device.

After the working current of the curing lamp 6 stabilizes, the motor 25 is started to drive the second threaded rod 26 to rotate. The second threaded rod 26 and the first moving block 28 are threaded together, and under the guidance of the second guide rod 27, the mounting base 4 moves linearly following the second moving block 29, allowing the printed material to pass under the curing lamp 6.

If it is not feasible, the scheme is adjusted and the test is repeated.
