Abstract
Description
Technical Field
[0001] This utility model belongs to the field of cigarette printing technology, specifically relating to a cigarette overprinting deviation detection device and a cigarette overprinting machine. Background Technology
[0002] The overprinting process in cigarette packaging production is crucial, determining the accuracy, color saturation, and overall aesthetics of the final product's design. The overprinting process is as follows: Paper passes through the first printing unit (where the paper is transported by conveyor rollers, and the printing rollers, partially placed in the ink cartridge, come into contact with the paper on the conveyor rollers for printing), where the first color (usually black or the main color) is printed. The printed color needs to be quickly cured by a drying device (hot air, infrared, UV curing, etc.) to prevent smudging and interference with subsequent overprinting. The paper then passes through subsequent printing units. The key to overprinting is that the paper's position must be precisely aligned with the design on the next printing plate before entering the next printing unit. When the paper enters the next printing unit, because the paper seams between the two printing units cannot be 100% aligned, a lateral deviation occurs (the lateral deviation is...). Figure 1 The generation of lateral deviation (in the X-axis direction) will inevitably cause abnormal product loss, thereby increasing production costs. Utility Model Content

[0027] To more clearly illustrate the technical solutions in the embodiments of this utility model and the prior art, the specific implementation methods of this utility model will be described below with reference to the accompanying drawings. Obviously, the accompanying drawings described below are only some embodiments of this utility model. For those skilled in the art, other drawings and other implementation methods can be obtained based on these drawings without any creative effort. Furthermore, the design orientation only indicates the relative positional relationship between the components, not the absolute positional relationship.
[0028] In the first aspect, this utility model embodiment provides a cigarette overprinting deviation detection device, please refer to... Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 It mainly includes an overlay disk 2 and a barcode scanning component 3.
[0029] In this embodiment, the cigarette registration deviation detection device includes a registration disk 2 and a barcode scanning component 3. The registration disk 2 is arranged on one side of the registration roller 1, and the barcode scanning component 3 is arranged around the registration disk 2. The registration disk 2 is coaxial with the registration roller 1, and the registration roller 1 and the registration disk 2 rotate synchronously with their rotation axes on the same straight line. This ensures that when the registration roller 1 rotates, the registration disk 2 and the registration roller 1 rotate around the same axis. A marking area 21 is arranged along the rotation direction of the registration disk 2, and multiple markings 22 are arranged at equal intervals in the marking area 21. The multiple markings 22 are connected along the rotation direction of the registration disk 2 to form a marking. When the overprinting roller 1 drives the overprinting disk 2 to rotate, the scanning component 3 will photograph the mark 22 in the marking area 21. Based on the photographed mark 22, the lateral deviation value during the overprinting process is determined. If the lateral deviation value occurs after changing rolls, the scanning component 3 will not be able to recognize the first mark 22 of the next roll after recognizing the last mark 22 of the previous roll. At this time, the scanning component 3 will send an electrical signal indicating the occurrence of the lateral deviation value to the cigarette overprinting machine. The cigarette overprinting machine will then stop and alarm, and perform maintenance and adjustment (adjusting the axial or circumferential movement position of the overprinting roller 1 or adjusting the paper tension). This application uses the overprinting disk 2 and the scanning component 3 to detect the marks on the overprinting disk 2 to determine the lateral deviation value during the overprinting process. Then, when the lateral deviation value occurs, the machine will stop for maintenance and adjustment. This allows for timely detection of the lateral deviation value during the cigarette overprinting process, thereby avoiding abnormal product loss and reducing production costs.
[0030] It is foreseeable that during the printing of cigarette boxes or other cigarette products, the ink at both ends of the printing roller 1 will be thrown out of the printing roller 1 due to centrifugal force. At this time, the ink is easy to splash onto the surrounding environment, thereby polluting the surrounding environment. Moreover, the ink is easy to splash onto the printing disk 2, thereby affecting the detection effect of the lateral deviation value of the printing disk 2. In order to reduce the degree of ink pollution to the surrounding environment, a baffle 4 is provided between the printing disk 2 and the printing roller 1. The baffle 4 is used to isolate the printing disk 2 from the printing roller 1.
[0031] In one embodiment, the baffle 4 includes a first plate 41 and a second plate 42 connected together. The first plate 41 is fixed between the registration disc 2 and the registration roller 1. The included angle between the first plate 41 and the second plate 42 is an obtuse angle, and the opening of the included angle between the first plate 41 and the second plate 42 faces the registration roller 1. By setting the baffle 4 with the first plate 41 and the second plate 42 having an obtuse angle, when the ink flies away from the registration roller 1, the second plate 42 will guide the blocked ink to the first plate 41, preventing the ink at the upper end of the baffle 4 from passing through to the side of the baffle 4 away from the printing roller, thereby improving the ink blocking effect of the baffle 4.
[0032] In one possible implementation, a first locking block 5 is provided on the side of the baffle 4 away from the printing roller 1, and a second locking block 6 is provided on the side of the baffle 4 close to the printing roller 1. The baffle 4 is also provided with a locking hole. The locking bolt passes through the first locking block 5 and the baffle 4 in sequence and is screwed to the second locking block 6, thereby locking the baffle 4 and preventing the baffle 4 from deflecting, thus ensuring the isolation effect of the baffle 4.
[0033] In one possible implementation, two side-by-side label rings are provided within the label area 21 to achieve compatibility with all layout methods. Furthermore, label 22 is a triangular label 22.
[0034] In one possible implementation, a cover 7 is provided on the side of the baffle 4 near the overprinting disk 2. The cover 7 is located on the outer periphery of the overprinting disk 2 and is used to isolate the overprinting disk 2 from the surrounding environment to prevent dust from adhering to the overprinting disk 2. This ensures that the barcode scanning component 3 can accurately obtain the position of the marking ring on the overprinting disk 2 and improves the detection effect of the lateral deviation value during the overprinting process.
[0035] Furthermore, the side of the cover 7 away from the baffle 4 is mesh-like, so that operators can observe the status of the overprinting disc 2 and thus stop the machine for maintenance in time when the overprinting disc 2 malfunctions.
[0036] In one possible implementation, the barcode scanning assembly 3 includes a fixing plate 31, a mounting plate 34, and a barcode amplifier 32. Preferably, the barcode amplifier 32 is a Honeywell 1900 series. The fixing plate 31 is fixedly connected to the housing 7, and the mounting plate 34 is fixed on the fixing plate 31. The mounting plate 34 is provided with a mounting ring 35 and a locking ring 36. The locking ring 36 is provided with a locking hole. The scanning end of the barcode amplifier 32 passes through the locking ring 36 and the mounting ring 35 in sequence. After the bolt is screwed into the locking hole, it abuts against the barcode amplifier 32, thereby fixing the barcode amplifier 32 on the mounting plate 34. The other end of the barcode amplifier 32 is connected to the controller of the cigarette overprinting machine. The scanning end of the barcode amplifier 32 is fixed by arranging the mounting ring 35 and the locking ring 36. The locking ring 36 is used to fix the scanning end of the barcode amplifier 32, and the mounting ring 35 is used together with the locking ring 36 to limit the position of the barcode amplifier 32 to ensure that the barcode amplifier 32 does not shake.
[0037] Furthermore, the fixing plate 31 is provided with two oblong holes 33 arranged side by side, and the mounting plate 34 is provided with mounting posts. The mounting posts pass through the oblong holes 33 and are screwed into the bolts, thereby locking the mounting plate 34. This allows the installation position of the barcode amplifier 32 to be adjusted to ensure that the barcode amplifier 32 is aligned with the mark 22 on the overprinting disk 2, thereby improving the detection effect of the lateral deviation value during the overprinting process.
[0038] Secondly, a cigarette overprinting machine is proposed, which includes the cigarette overprinting deviation detection device described in the first aspect.
