Description

Technical Field

[0001] This application relates to the field of trademark printing technology, and in particular to an integrated cigarette label printing machine. Background Technology

[0002] Cigarette labels refer to the trademarks on cigarette boxes. The printing method used is mostly gravure printing. A gravure machine has an upper guide roller, a lower printing plate roller, and an ink pool for supplying ink. Part of the printing plate roller is immersed in the ink pool. As the printing plate roller rotates, the part of the printing plate roller that has been in contact with ink rotates upward and contacts the printing paper to achieve printing. The printed part rotates downward and is immersed in the ink pool again. This cycle is repeated to achieve the printing of cigarette labels. Older cigarette labels were mostly designed with a single color structure, meaning that printing could be completed by one gravure machine. With the development of product diversification, single-color trademarks have gradually lost their distinctiveness, and multiple gravure machines need to be used in conjunction to achieve printing.

[0003] The existing integrated cigarette label printing machine has the following defects: for example, when two roll gravure machines are used together, the patterns of the two colors are easily misaligned, resulting in blurry trademarks. Moreover, the adjustment between the two roll gravure machines is mostly done manually or electrically independently. That is, after the trademark pattern is found to be blurry, the machine is stopped for adjustment. By this time, a batch of unqualified products has already been produced, resulting in economic losses. The downtime for adjustment also affects production efficiency. Summary of the Invention

[0004] The purpose of this application is to provide an integrated cigarette label printing machine to solve the problem that when two roll-to-roll printing machines are used together, the patterns of the two colors are easily misaligned, resulting in blurred trademarks. In addition, the adjustment between the two roll-to-roll printing machines is mostly done manually or electrically, which means that after the trademark pattern is found to be blurred, the machine is stopped for adjustment. By this time, a batch of unqualified products has already been produced, resulting in economic losses. The machine stoppage for adjustment also affects production efficiency.

[0005] To achieve the above objectives, the technical solution adopted in this application is as follows: an integrated cigarette label printing machine, comprising an adjustable base, a first gravure printing machine, and a second gravure printing machine.

[0018] As another preferred embodiment, the bidirectional adjustment mechanism includes a first threaded rod, a second threaded rod, and a threaded sleeve. The threaded sleeve is rotatably connected to the fixed seat. Both the first threaded rod and the second threaded rod have one end threadedly connected to the threaded sleeve. One end of the first threaded rod is fixedly connected to the first mounting seat, and one end of the second threaded rod is fixedly connected to the second mounting seat.

[0019] The outer side of the threaded sleeve has a gear portion, and the bottom of the sliding adjusting plate has a rack portion, which meshes with the gear portion.

[0020] A further preferred embodiment includes a hot air blower, which is located between the first winding die and the second winding die.

[0021] As a preferred embodiment, a transmission gear and a synchronizing gear are fixedly connected to the end of the second roller away from the connecting body.

[0022] As another preferred embodiment, it further includes: a timing belt, wherein guide pulleys are connected to the sides of both the first winding machine and the second winding machine, and the timing belt is connected to the two guide pulleys, wherein the teeth of the timing belt face outward and mesh with the timing gear;

[0023] It also includes a tensioner pulley, which is located inside the timing belt.

[0024] Further preferably, it also includes: a conveying assembly; the conveying assembly includes: a housing, the housing having two parallel sides, each of which has a sliding opening, a sliding member slidably connected in one of the sliding openings, a rotating shaft provided on the inner side of the housing, a transmission cylinder fixedly connected to the side of the rotating shaft, one end of the rotating shaft being rotatably connected to the sliding member, a heat-conducting plate provided on the inner side of the housing and below the rotating shaft, a steam box provided at the bottom of the heat-conducting plate, and a heat-insulating material provided on the outer side of the steam box;

[0025] A fixed plate frame is fixedly connected to the outer side of the housing. An elastic plate is connected to the top of the fixed plate frame. A movable plate frame is fixedly connected to the top of the elastic plate frame. A reduction gearbox is fixedly connected to the top of the movable plate frame.

[0026] As a preferred embodiment, the transmission cylinder is provided in three sets, and an elastic ring is provided on the outer side of the transmission cylinder, the outer ring of the elastic ring being a smooth surface.

[0027] Alternatively, both the identifier A and the identifier B are cameras.

[0028] Further preferably, it also includes an alarm module, which is connected to the processor.

[0029] Compared with the prior art, the beneficial effects of this application are as follows:

[0030] (1) In this invention, by setting up a gravure printing machine composed of two sections (first printing roller and second printing roller), the patterns printed on the two sections of printing roller are designed differently and used with special printing paper. In this way, when printing two-color cigarette labels, pattern A will be printed first in the first printing area and then pattern B, and pattern B will be printed first in the second printing area and then pattern A. When the finished product after printing has a slight deviation, the patterns in the two printing areas will form a sharp contrast (magnifying the deviation by two times). The identification device A and identification device B of the monitoring system are used to identify and collect the corresponding position images. The comparison module is used to compare and can detect the deviation in time. Then, the adjustment cylinder is controlled to adjust the distance between the first mounting seat and the second mounting seat, so as to detect the misalignment in time and adjust it in time, ensuring that the trademarks printed by the two gravure printing machines are within the qualified range, and can achieve continuous and efficient work without stopping the machine or production, thereby improving the printing efficiency of cigarette labels.

[0031] (2) In this invention, by improving the structure of the printing roller, an inner cylinder, absorbent cotton, and replaceable printing roller are arranged sequentially from the inside out. An inner ring is fixed inside the inner cylinder, so that the inside of the inner cylinder forms a space that can hold ink. When the printing roller rotates, the ink will flow downward under the action of gravity and will always be in the lower holding area. It will then pass through the overflow hole and enter the absorbent cotton. After the absorbent cotton rotates once, it can be filled with ink. A squeezing roller is set up. The squeezing roller squeezes the printing roller structure, squeezing some ink through the capillary holes to the outside of the replaceable printing roller. When it comes into contact with the squeezing roller, the ink is evenly spread. When it rotates to contact the printing paper, printing is performed. This structure saves ink more than the printing roller immersing itself in the ink pool and dipping the ink in the ink-taking direction. The printed pattern can dry quickly. Moreover, only a small amount of ink is needed during operation. The ink is continuously replenished by the ink addition system. Once the machine malfunctions or is under maintenance, there will be no problem of a large amount of ink being wasted. Attached Figure Description

[0045] The present application will be further described below with reference to specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0046] In the description of this application, it should be noted that the terms "center", "lateral", "longitudinal", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", etc., which indicate the orientation and positional relationship based on the orientation or positional relationship shown in the accompanying drawings, are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and should not be construed as limiting the specific protection scope of this application.

[0047] It should be noted that the terms "first," "second," etc., in the specification and claims of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.

[0048] The terms “comprising” and “having”, and any variations thereof, in the specification and claims of this application are intended to cover non-exclusive inclusion, for example, a process, method, system, product, or device that includes a series of steps or units is not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such process, method, product, or device.

[0049] like Figure 1-11 The integrated cigarette label printing machine shown includes an adjustable base 1, a first gravure machine 2, and a second gravure machine 3. The top of the adjustable base 1 has a first mounting seat 102 and a second mounting seat 103 with adjustable spacing. The first gravure machine 2 is fixedly connected to the top of the first mounting seat 102, and the second gravure machine 3 is fixedly connected to the top of the second mounting seat 103. By controlling the control structure in the adjustable base 1, the spacing between the first mounting seat 102 and the second mounting seat 103 can be adjusted, thereby adjusting the spacing between the first gravure machine 2 and the second gravure machine 3.

[0050] A cigarette label design with two colors is divided into two layers. The two different colors of the design are printed using a first roll engraving machine 2 and a second roll engraving machine 3. The distance between the first roll engraving machine 2 and the second roll engraving machine 3 is adjusted to ensure that the relative positions of the designs printed by the first roll engraving machine 2 and the designs printed by the second roll engraving machine 3 are maintained, thus avoiding problems such as design overlap and blurring.

[0051] Reference Appendix Figures 4-6This embodiment provides a specific adjustable base 1, which includes a fixed base 101. A first mounting base 102 and a second mounting base 103 are slidably connected to the top of the fixed base 101. The sliding directions of the first mounting base 102 and the second mounting base 103 are on the same straight line. A bidirectional adjustment mechanism 104 is provided between the first mounting base 102 and the second mounting base 103. The bidirectional adjustment mechanism 104 is used to move the first mounting base 102 and the second mounting base 103 relative to or opposite to each other. A sliding adjustment plate 105 is slidably connected to the top of the fixed base 101. The sliding adjustment plate 105 is driven by the bidirectional adjustment mechanism 104, that is, the adjustment mode of the bidirectional adjustment mechanism 104 is converted into the linear adjustment mode of the sliding adjustment plate 105. A connecting plate 106 is fixedly connected to one end of the sliding adjustment plate 105. An adjustment cylinder 107 is connected to the fixed base 101, and the adjustment cylinder 107 is used to drive the linear sliding.

[0052] The specific adjustment method is as follows: the adjustment cylinder 107 moves to push or pull the sliding adjustment plate 105 to slide, thereby driving the bidirectional adjustment mechanism 104 to move relative to or away from the first mounting seat 102 and the second mounting seat 103, adjusting the distance between them so that the patterns printed by the first roll gravure machine 2 and the second roll gravure machine 3 correspond in position.

[0053] Reference Appendix Figure 4 This embodiment provides a specific bidirectional adjustment mechanism 104, which includes a first threaded rod 1041, a second threaded rod 1042, and a threaded sleeve 1043. The threaded sleeve 1043 is rotatably connected to the fixed seat 101. The threaded sleeve 1043 is connected by two sets of bearing structures. Both the first threaded rod 1041 and the second threaded rod 1042 have one end threadedly connected to the threaded sleeve 1043. One end of the first threaded rod 1041 is fixedly connected to the first mounting seat 102, and one end of the second threaded rod 1042 is fixedly connected to the second mounting seat 103.

[0054] By rotating the threaded sleeve 1043, the overall length of the bidirectional adjustment mechanism 104 can be adjusted by utilizing the threaded connection between the threaded sleeve 1043 and the first threaded rod 1041 and the second threaded rod 1042, thereby pulling the first winding machine 2 and the second winding machine 3 closer or pushing them apart.

[0055] In one specific transmission structure, the outer side of the threaded sleeve 1043 has a gear section, and the bottom of the sliding adjustment plate 105 has a rack section. The rack section meshes with the gear section, that is, the sliding rack drives the gear section to rotate. This method is a precise adjustment that can make the patterns printed by the first roll of gravure 2 and the second roll of gravure 3 completely overlap.

[0056] Reference Appendix Figure 1The first roll embossing machine 2 and the second roll embossing machine 3 have the same structure. Here, only the specific structure of the second roll embossing machine 3 will be described. Those skilled in the art can understand the specific structure of the first roll embossing machine 2 based on the corresponding relationship.

[0057] Specifically, the second roll gravure machine 3 includes guide rollers 6, printing roller structure 7, and extrusion rollers 8. The guide rollers 6 are driven by a motor and are a conventional structure, so they will not be described in detail again.

[0058] Reference Appendix Figure 9 Specifically, the printing roller structure 7 includes a connecting body 701, a first printing roller 702, and a second printing roller 703. The connecting body 701 has a roller portion in the middle and small-diameter connecting portions at both ends. The first printing roller 702 and the second printing roller 703 are symmetrically connected to the two ends of the connecting body 701, and the printing patterns on the first printing roller 702 and the second printing roller 703 are different.

[0059] Reference Appendix Figure 2 , Figure 9 If a pattern is formed by superimposing pattern A and pattern B, then the first printing roller 702 on the second gravure machine 3 corresponds to pattern A, and the second printing roller 703 corresponds to pattern B. The first printing roller 702 on the first gravure machine 2 corresponds to pattern B, and the second printing roller 703 corresponds to pattern A. After printing, the resulting pattern is the total pattern.

[0060] Reference Appendix Figure 9 , 10 The second printing roller 703 includes an inner cylinder 7031, absorbent cotton 7034, and a replaceable printing roller 7035 arranged sequentially from the inside to the outside. The absorbent cotton 7034 is located between the inner cylinder 7031 and the replaceable printing roller 7035. The interior of the inner cylinder 7031 is used to hold ink, and the absorbent cotton 7034 is used to temporarily absorb ink. An overflow hole 7032 is provided on the side of the inner cylinder 7031, through which ink is absorbed into the absorbent cotton 7034. The side of the replaceable printing roller 7035 is provided with capillary pores, and the outer side of the replaceable printing roller 7035 is the printed pattern. An inner ring 7033 is provided on the inner wall of the inner cylinder 7031.

[0061] The ink inside the inner cylinder 7031 will move closer to the bottom. At this time, the inner ring 7033 can block the end part to prevent the ink from overflowing from the port of the inner cylinder 7031. As the printing roller structure rotates, the lower part of the inner cylinder 7031 will be continuously replaced, which can sequentially achieve the immersion of ink into the absorbent cotton 7034 ring.

[0062] When the second printing roller 703 rotates, it will squeeze the pressure roller 8. During the squeezing, the ink on the absorbent cotton 7034 will be squeezed out. Part of it will flow back into the inner cylinder 7031 through the overflow hole 7032, and the other part of the ink will reach the outer surface of the replaceable printing roller 7035 through the capillary. After contacting the pressure roller 8, the ink on the surface will be evenly spread. With the subsequent rotation, a printing pattern will be formed on the printing paper 5.

[0063] Reference Appendix Figure 9 This embodiment also includes an ink adding system, which consists of an ink cartridge, a liquid supply pump, and a detection element. One end of the ink adding tube 706 of the ink adding system is located inside the inner cylinder 7031.

[0064] When the detection element detects that there is not enough ink inside the inner cylinder 7031, it controls the liquid supply pump to add ink to the inside of the inner cylinder 7031. This process is continuous. As long as there is always a small amount of ink inside the inner cylinder 7031, the printing work can be completed.

[0065] Reference Appendix Figure 2 The printing paper 5 used in the integrated cigarette label printing machine includes, from top to bottom: first side area 13, first printing area 14, middle area 15, second printing area 16, and second side area 17.

[0066] It has a first printing area 14 and a second printing area 16, which correspond to the first printing roller 702 and the second printing roller 703. The first side area 13, the middle area 15, and the second side area 17 are used for transmission.

[0067] Reference Appendix Figures 1-11 This embodiment also includes: a monitoring system 11, which has:

[0068] Recognizer A1101 is used to identify the pattern in the first printing area 14;

[0069] Recognizer B1102 is used to identify the pattern in the second printing area 16;

[0070] Control module 1106 receives information and performs corresponding control actions;

[0071] The comparison module 1104 receives information obtained by the recognizer A1101 and the recognizer B1102, and compares the obtained information.

[0072] The processor 1103 receives the comparison results from the comparison module 1104, processes and judges the information, takes corresponding measures, and controls the operation of the control module 1106.

[0073] Alarm module 1105 is connected to processor 1103.

[0074] The output end of the regulating cylinder 107 is fixedly connected to the connecting plate 106, and the control end of the regulating cylinder 107 is connected to the control module 1106.

[0075] Both the A1101 and B1102 recognition devices are cameras.

[0076] Recognizers A1101 and B1102 transmit the recognized image information to the comparison module 1104. The comparison module 1104 compares the features in the pattern and feeds back the comparison results to the processor 1103. The processor 1103 processes the feedback information accordingly and then performs the corresponding action.

[0077] Specifically, the operations include the following: 1. If the overlap is within the normal range, no adjustment is needed; 2. If the overlap is abnormal and can be adjusted, control the adjusting cylinder 107 to perform the corresponding action (including adjusting the size and direction); 3. If the overlap is abnormal and cannot be adjusted, control the alarm module 1105 to issue an alarm message.

[0078] Reference Appendix Figure 1 This embodiment also includes a hot air blower 4, which is located between the first roll gravure machine 2 and the second roll gravure machine 3. The hot air generated by the hot air blower 4 dries the pattern printed by the first roll gravure machine 2 to avoid affecting the operation of the second roll gravure machine 3.

[0079] Reference Appendix Figure 9 , Figure 10 In this embodiment, a transmission gear 704 and a synchronization gear 705 are fixedly connected to the end of the second printing roller 703 away from the connecting body 701. The transmission gear 704 drives the output end of the motor used to drive the second printing roller 703 to rotate. The synchronization gear 705 is used to ensure that the printing roller structure 7 of the first winding machine 2 and the second winding machine 3 rotate synchronously.

[0080] Specifically, it also includes: a timing belt 18, guide pulleys 9 connected to the sides of the first winding machine 2 and the second winding machine 3, the timing belt 18 being connected to the two guide pulleys 9, the teeth of the timing belt 18 facing outwards and meshing with the timing gear 705.

[0081] The outer side of the synchronous belt 18 meshes with the synchronous gear 705. If the printing roller structures 7 of the first winding die 2 and the second winding die 3 do not rotate synchronously, a misalignment problem will occur. The synchronous belt 18 can correct this by applying resistance to the faster speed and applying power to the slower speed, ensuring that the two speeds are the same.

[0082] The tensioning pulley 10 is located inside the synchronous belt 18 and is used to tension the synchronous belt 18. The tensioning pulley 10 adopts an elastic structure, which can still ensure the tension of the synchronous belt 18 as the first winding machine 2 and the second winding machine 3 move.

[0083] Reference Appendix Figure 7 , Figure 8 It also includes a conveying assembly 12; the conveying assembly 12 includes: a housing 1201, the housing 1201 having two parallel sides, each of which has a sliding opening 1202, a sliding member 1203 slidably connected in one of the sliding openings 1202, a rotating shaft 1204 provided on the inner side of the housing 1201, a transmission cylinder 1205 fixedly connected to the side of the rotating shaft 1204, one end of the rotating shaft 1204 being rotatably connected to the sliding member 1203, the sliding member 1203 being used to stabilize the rotating shaft 1204, a heat-conducting plate 1211 provided on the inner side of the housing 1201 and below the rotating shaft 1204, a steam box 1210 provided at the bottom of the heat-conducting plate 1211, and a heat-insulating material 1212 provided on the outer side of the steam box 1210.

[0084] The steam box 1210 is connected to the steam system via a pipe to heat the heat-conducting plate 1211, thereby increasing the drying speed of the printed pattern on the printing paper 5.

[0085] The rotating shaft 1204 rotates, driving the transmission drum 1205 to rotate, applying a driving force to the printing paper 5. Since the transmission drum 1205 can slide up and down, this driving force is limited. That is, when the first gravure machine 2 and the second gravure machine 3 are not working, the friction at this point cannot drive the printing paper 5 to move. The movement of the printing paper 5 is driven by the first gravure machine 2 and the second gravure machine 3. The pulling force provided by the transmission drum 1205 is only an assist.

[0086] A fixed plate frame 1206 is fixedly connected to the outer side of the housing 1201. An elastic plate is connected to the top of the fixed plate frame 1206. A movable plate frame 1207 is fixedly connected to the top of the elastic plate. The design of the elastic plate allows the movable plate frame 1207 to move up and down elastically. A reduction gearbox 1208 is fixedly connected to the top of the movable plate frame 1207. A drive motor 1209 is fixedly connected to the side of the reduction gearbox 1208. The output end of the drive motor 1209 is connected to the input shaft of the reduction gearbox 1208. The output shaft of the reduction gearbox 1208 is connected to the rotating shaft 1204 through a coupling.

[0087] When in operation, the drive motor 1209 drives the reduction gearbox 1208. After reduction, the power is transmitted to the rotating shaft 1204, which drives the rotating shaft to rotate, and in turn drives the transmission cylinder 1205 to rotate.

[0088] The transmission cylinder 1205 is provided with three sets of elastic rings, and the outer ring of the elastic ring is a smooth surface.

[0089] This allows the elastic ring to slip easily on the surface of the printing paper 5, so that the conveying component 12 only provides assistance and the movement of the printing paper 5 depends on the first gravure machine 2 and the second gravure machine 3, so that the printing paper 5 and the printing roller structure 7 move synchronously.

[0090] Working principle: When in use, select a printing paper 5 of appropriate width, determine the positions of the first side area 13, the first printing area 14, the middle area 15, the second printing area 16, and the second side area 17, and start the first roll gravure machine 2, the second roll gravure machine 3, the hot air blower 4, and the conveying assembly 12 to maintain the working state.

[0091] The conveying assembly 12 provides assistance, making the printing paper 5 move very easily. Under the action of the guide rollers 6 on the first gravure machine 2 and the second gravure machine 3 and the printing roller structure 7, the printing paper 5 moves forward synchronously.

[0092] During the rotation of the printing roller structure 7, the ink in the inner cylinder 7031 passes through the overflow hole 7032 and reaches the absorbent cotton 7034. When the replaceable printing roller 7035 is squeezed by the extrusion roller 8, some ink flows through the capillary holes to the outside of the replaceable printing roller 7035 and prints patterns on the printing paper 5 as the printing roller structure 7 rotates.
