DETAILED DESCRIPTION

[0021] The following is a detailed description of a deviation correction mechanism for a packaging bag color printing device provided by the utility model in combination with the accompanying drawings and specific embodiments. At the same time, it is explained here that in order to make the embodiments more detailed, the following embodiments are the best and preferred embodiments. For some known technologies, those skilled in the art may also adopt other alternative methods to implement them; and the accompanying drawings are only for more specific description of the embodiments, and are not intended to specifically limit the utility model.

[0022] like Figure 1 - Figure 3 As shown, the embodiment of the utility model provides a deviation correction mechanism for a packaging bag color printing device, including a box body 1, both end walls of which are provided with through grooves 2, the through grooves 2 are close to the bottom of the box body 1, and are in the form of an elongated rectangular groove structure as a whole, for conveying packaging bags, and the top of the box body 1 is provided with a slide rail 4 perpendicular to the traveling direction of the packaging bags, and the radial cross section of the slide rail 4 is dovetail-shaped; a horizontal plate 9 is fixedly connected to the two side walls inside the box body 1 in a direction parallel to the through groove 2, and two illuminometers 10 symmetrically distributed with respect to the center position of the box body 1 are provided above the horizontal plate 9; a sliding seat 5 is slidably connected with the slide rail 4, and two ends of the sliding seat 5 are connected by two parallel side plates 7 A deviation-correcting roller 8 is rotatably connected, of which two are provided and are parallel to each other and arranged on both sides above the line connecting the two illuminometers 10, and the deviation-correcting roller 8 is arranged in parallel with the horizontal plate 9; a lighting lamp 12 is fixedly connected to the top of the box body 1 through a U-shaped plate 11, and the lighting lamp 12 is located between the sliding seat 5 and the deviation-correcting roller 8. The lighting lamp 12 is a long rectangular structure, and the relatively long central axes at both ends are distributed up and down with the line connecting the two illuminometers 10. The light lumen of the lighting lamp 12 is preferably in the range of 500~1500ANSI, and a plurality of U-shaped plates 11 are provided to improve the fixing stability of the lighting lamp 12.

[0023] By arranging a lighting lamp 12 and two illuminometers 10 on both sides of the packaging bag, the irradiation area of ​​the lighting lamp 12 is blocked by the packaging bag, resulting in a difference in the detection values ​​on the two illuminometers 10. According to the difference, the correction mechanism (i.e., the sliding seat 5, the correction roller 8, and the side plate 7) is driven to make a linear motion perpendicular to the conveying direction of the packaging bag. Under the friction between the correction roller 8 and the packaging bag, the conveying position of the packaging bag is adjusted, thereby correcting the conveying of the packaging bag.

[0024] like Figure 3 As shown, a slide groove 6 is provided on the top of the sliding seat 5, and the slide groove 6 is slidably connected with the slide rail 4, wherein the radial cross-sectional shape of the slide groove 6 is the same as that of the slide rail 4, so that the sliding seat 5 can move linearly along the setting direction of the slide rail 4 while being suspended by the slide rail 4.

[0025] like Figure 1As shown, it also includes an electric push rod 3, which is fixedly connected to the outer wall of the box body 1. The output end of the electric push rod 3 passes through the side wall of the box body 1 and is fixedly connected to the outer wall of one of the side panels 7. The electric push rod 3 is electrically connected to the illuminance meter 10 through a control module. The control module preferably adopts an STM32C8T6 model single-chip microcomputer, which processes the detection values ​​from the two illuminance meters 10 and controls the advancement and retraction of the electric push rod 3 based on the difference judgment.

[0026] Through this setting, when there is a difference in the lumen measured by the two illuminance meters 10, the control module receives a signal and sends a command to the electric push rod 3, the electric push rod 3 starts, and pushes the sliding seat 5 to the side of the two illuminance meters 10 with a larger lumen value, until the lumen values ​​detected by the two illuminance meters are the same, the control module receives a signal and sends a stop command, so that the electric push rod 3 is closed, wherein the two illuminance meters 10 are set with a ±10ANSI difference threshold, retaining a certain accuracy error, to avoid the control module repeatedly starting and closing the electric push rod 3, thereby increasing the failure rate.

[0027] like Figure 2 As shown, it also includes a steering roller 13. Two steering rollers 13 are provided and are respectively arranged near the positions of the two through slots 2 inside the box body 1. The steering roller 13 and the deviation correction roller 8 are arranged parallel to each other.

[0028] By setting the steering roller 13 and cooperating with the two correcting rollers 8, the packaging bag routing is arranged in a trapezoidal structure, which exerts a certain tension on the packaging bag and facilitates the packaging bag to pass through the through slot 2 in a horizontal state without contacting the side wall of the through slot 2.

[0029] The technical solution provided by the utility model, when the packaging bag is color-printed, the packaging bag is sequentially passed through the front through slot 12, below the front steering roller 12, above the two deviation-correcting rollers 8, below the rear steering roller 12 and the rear through slot 2 according to the process requirements, so that the packaging bag moves in a trapezoidal structure. At this time, the lighting lamp 12 is located above the packaging bag. When the packaging bag is located between the two illuminometers 10 (refer to Figure 4 ), the illumination area of ​​the two illuminometers 10 for the lighting lamp 12 is the same under the shields on both sides of the packaging bag body, so the lumen data detected by the two illuminometers are the same. When the packaging bag is offset (refer to Figure 5), since the packaging bag is offset to the right, the illuminance meter 10 on the left receives a relatively larger irradiation area of ​​the illuminance lamp 12 than the illuminance meter 10 on the right, so the data detected by the illuminance meter 10 on the left is larger than that on the right. At this time, the control module sends an instruction to the electric push rod 3 after data comparison processing, so that it pushes the correction component to the left as a whole, thereby resetting the packaging bag so that it is always directly below the center of the illuminance lamp. Similarly, normal correction work can be performed for packaging bags of different widths within a certain range without debugging. It is particularly noted that by arranging the lighting component (i.e., the illuminance lamp 12) and the sensing component (i.e., the illuminance meter 10) inside the box body 1, the box body 1 is a box-type structure, which avoids the interference of natural light in the external environment on the sensing component and affects the accuracy of the device, and a U-shaped groove is provided in the middle of the bottom of the side panel 7 to avoid the side panel 7 blocking the light of the illuminance lamp 12.

[0030] The present invention covers any substitution, modification, equivalent method and scheme made on the essence and scope of the present invention. In order to make the public have a thorough understanding of the present invention, specific details are described in detail in the above preferred embodiments of the present invention, and those skilled in the art can fully understand the present invention without the description of these details. In addition, in order to avoid unnecessary confusion about the essence of the present invention, well-known methods, processes, procedures, components and circuits are not described in detail.

[0031] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
