Description

Technical Field

[0001] The utility model belongs to the technical field of laser inkjet printer switching devices and provides a product-changing laser inkjet printer fast switching device. Background Art

[0002] Any product needs to be packaged with packaging materials before it can enter the later stages of shipment, transportation, and sales. The laser inkjet printer uses the laser emitted from the marking area to mark the product information on the surface of the packaging material. Based on this information, we can understand the product parameters in a timely manner and facilitate product management.

[0003] When changing the first-line products, it is necessary to frequently pull the pull rod to switch the height and depth of the inkjet printer. After the product is changed, the marking position changes. The product information is marked on the correct position on the surface of the product packaging material by switching the height and depth. At present, there is a lack of pull rod positioning and limiting measures on the inkjet printer, which causes the laser inkjet printer to mark the product packaging material misplaced. When using a paint pen to make markings, it is not convenient to remove the original residual marks during later adjustments, making the marks too confusing and unclear, and unable to be re-marked. Personnel cannot quickly and accurately adjust to the best printing position. The printing position is misplaced, and experiments must be repeated every time adjustments are made. Multiple experiments are required to adjust the pull rod position to determine the correct marking position, which wastes both time and packaging materials. Utility Model Content

DETAILED DESCRIPTION

[0019] See also Figure 1-3 The utility model provides a technical solution: a product-changing laser inkjet printer fast switching device, comprising a pair of stacked support plates 18, each of which is provided with a fixing rod 1 on the outside of the support plate 18, and the two fixing rods 1 are arranged crosswise, and adjustment blocks 15 are installed on both sides of the head and tail between the outer end of the support plate 18 and the inner end of the fixing rod 1, and a groove 2 11 is provided on the outer surface of the adjustment block 15 and close to the support plate 18. A perspective piece 2 12 is inlaid in the groove 2 11, and a scale bar 2 13 is engraved on the outer surface of the adjustment block 15 and close to the fixing rod 1. A groove 1 8 is provided on the outer surface of the fixing rod 1 and away from the adjustment block 15. A perspective piece 1 9 is inlaid in the groove 1 8, and a scale bar 10 is engraved on the outer surface of the fixing rod 1 and close to the adjustment block 15. A pull rod 16 is interspersed between the two adjustment blocks 15 on the same straight line. The two pull rods 16 are interspersed between the two adjustment blocks 15 on the same straight line. The pull rods 16 are arranged in a cross pattern. The moving pull rod 16 drives the adjusting block 15 to move. The moving pull rod 16 adjusts the position of the adjusting block 15. The adjusting block 15 faces different values ​​of the scale bar 10. The scale bar 13 moves along the scale bar 10 as the adjusting block 15 moves. The "zero position" scale value of the scale bar 10 corresponds to the "zero position" scale value of the scale bar 2 13. A pair of reflective sheets 17 are installed on the outer wall between the support plates 18. A laser rangefinder 14 is installed at one end of the adjusting block 15 close to the support plate 18. The reflective sheet 17 is aligned one by one with the two laser rangefinders 14 on the same straight line. The laser rangefinder 14 is started and reset to zero. The laser rangefinder 14, the scale bar 10 and the scale bar 2 13 display "zero", thereby achieving the correction effect of the laser rangefinder 14, the scale bar 10 and the scale bar 2 13.

[0020] The end of the adjustment block 15 close to the fixed rod 1 is equipped with a photoelectric sensor 27, and the end of the photoelectric sensor 27 away from the adjustment block 15 is equipped with a photoelectric sensor 6 in a one-to-one correspondence. The photoelectric sensor 6 is located at the outer end of the fixed rod 1, and the pull rod 16 is continuously moved until the "zero position" of the scale bar 10 is staggered with the "zero position" of the scale bar 2 13, and the "zero position" of the scale bar 2 13 points to the values ​​of different positions of the scale bar 10 one by one. The photoelectric sensor 27 moves with the movement of the adjustment block 15, and the photoelectric sensor 27 moves along the surface of the scale bar 10, and the photoelectric sensor 27 points to different positions on the surface of the scale bar 10;

[0021] The photoelectric sensor 6 is fixed with a bracket 5 arranged on the outer end of a fixed rod 1. A screw rod 3 is interspersed between the tail ends of multiple brackets 5 on the same straight line. The head and tail ends of the screw rod 3 are respectively fixed on the head and tail sides of the outer surface of the adjacent fixed rod 1. The outer end of the fixed rod 1 is provided with a guide rail 2 slidably connected to the tail ends of multiple adjacent brackets 5 on the same side. The guide rail 2 is located between two screw rods 3. The screw 3 is slidably connected to the tail ends of the adjacent brackets 5. The outer surfaces of the screws 3 are all threadedly connected with ingot nuts 4 that are respectively tightly attached to the surfaces of the adjacent brackets 5. The ingot bolts 4 are loosened, and the ingot bolts 4 are separated from the corresponding surfaces of the brackets 5, and the brackets can be moved manually. 5 slides along the inside of the guide rail 2, and the bracket 5 moves along the surface of the screw rod 3 to change the position of the bracket 5 on the surface of the screw rod 3. The photoelectric sensor 1 6 moves with the movement of the bracket 5, and the photoelectric sensor 1 6 and the photoelectric sensor 2 7 produce relative movement. The photoelectric sensor 2 7 moves away from the previous photoelectric sensor 1 6 and approaches the next photoelectric sensor 1 6 until the photoelectric sensor 2 7 is aligned with the adjacent photoelectric sensor 1 6. Therefore, by loosening the ingot nut 4, the position of the photoelectric sensor 1 6 on the outer end of the fixed rod 1 can be adjusted by moving the bracket 5, so that the photoelectric sensor 1 6 and the adjacent photoelectric sensor 2 7 correspond to each other;

[0022] Re-tighten the ingot bolt 4, the ingot bolt 4 is tightly attached to the corresponding bracket 5 again, the ingot bolt 4 restricts the bracket 5 from moving with the guide rail 2 and the screw 3 respectively, and the adjusted photoelectric sensor 6 can be fixed and placed again, different photoelectric sensors 6 are aligned with different photoelectric sensors 2 7, the infrared rays emitted by the photoelectric sensor 6 are received by the corresponding photoelectric sensor 2 7, the photoelectric sensor 1 6 and the photoelectric sensor 2 7 are used together to generate a light signal of the alignment position of the two, the indicator lights set on the surface of the photoelectric sensor 1 6 and the photoelectric sensor 2 7 are lit, and the human eye can intuitively judge the light of these indicator lights to know whether the adjustment block 15 has moved to the appropriate position, in addition, the photoelectric sensor 1 6 and the photoelectric sensor 2 7 are used together to convert the light signal into an electrical signal and transmit it to the internal control circuit of the inkjet printer, so that the inkjet printer can record that the pull rod 16 adjusts the adjustment block 15 to the appropriate position, the scale bar 10 and the scale bar 2 13 are used together to realize the function of preliminary positioning of the adjustment block 15, and the photoelectric sensor 1 6 and the photoelectric sensor 2 7 are used together to realize the function of locking the adjusted position of the adjustment block 15;

[0023] The laser emitted by the laser rangefinder 14 irradiates the surface of the reflective sheet 17 to cause mirror reflection. The reflective sheet 17 reflects the laser back to the laser rangefinder 14. The laser rangefinder 14 can accurately calculate the position of the adjustment block 15 on the surface of the pull rod 16 according to the reflected laser distance. Use hard paper to cut into a shape of paper strips with the same size as the groove 1 8 and the groove 2 11, respectively remove the perspective sheet 1 9 and the perspective sheet 2 12 from the inside of the groove 1 8 and the groove 2 11, and embed the paper strips into the inside of the groove 1 8 and the groove 2 11 respectively. According to the pull rod 16, the adjustment block 15 is driven on the scale. The scales indicated on the scale bar 10 and the scale bar 2 11 are marked with upper and lower limit lines on the paper strips with different colors of paint pens (markers), and the data values ​​are marked next to the marks. After the upper and lower limit lines are marked on the paper strips with the same size as the groove 1 8 and the groove 2 11, the perspective sheet 1 9 and the perspective sheet 2 12 are used to re-embed the groove 1 8 and the groove 2 11, respectively, so that the marked paper strips are firmly installed in the groove 1 8 and the groove 2 11. The perspective sheet 1 9 and the perspective sheet 2 12 can not only intuitively know the position of the mark but also protect the upper and lower limit line marks;

[0024] When the upper and lower limit line marks need to be modified later, re-cut a hard paper strip with the same size as the groove 1 8 and the groove 2 11, and re-mark the upper and lower limit line marks according to the above method. The upper and lower limit line marks can be changed by replacing the original paper strip, which is convenient for removing the original residual marks and re-marking the upper and lower limit line marks;

[0025] According to the positions of the upper and lower limit line marks, combined with the laser rangefinder 14, scale bar 10, scale bar 2 13, reflector 17, photoelectric sensor 1 6 and photoelectric sensor 2 7, the pull rod 16 moves the positioning block accurately to the marked position, and the photoelectric sensor 1 6 and the photoelectric sensor 2 7 are used together to achieve the effect of quickly switching the corresponding positions of the pull rod 16 and the adjustment block 15. There is no need to conduct experiments to re-determine the positions of the pull rod 16 and the adjustment block 15 during later adjustments. Each time the product is changed in the later stage, it is only necessary to adjust the two stretching rods 16 to the corresponding marked positions to quickly adjust the printing position, which saves switching time and is conducive to improving production efficiency.
