Abstract
Description
Technical Field
[0001] This application relates to the field of color mark printing equipment manufacturing technology, and in particular to a flexible packaging paper color mark printing module. Background Technology
[0002] Plastic packaging is a common packaging material, generally involving seven steps: raw material preparation, printing, lamination, curing, cutting, bag making, and quality control. In the cutting stage, color-coded markers are typically used on the edges of the packaging bag to position the cutting blade. The machine needs to accurately determine the cutting position. By setting specific color-coded markers (such as black, white, or other high-contrast colored lines) on the packaging bag, color-coded sensors can accurately identify these markers and trigger the cutting mechanism to cut at the marked locations, ensuring accurate cutting of the packaging bag.
[0003] In existing technologies, inkjet printing equipment is commonly used to print color marks on packaging bags. Common inkjet printing equipment mainly includes an unwinding mechanism, a traction mechanism, a rewinding mechanism, and a printing module. After the raw material is fed out by the unwinding mechanism, it is pulled by the traction mechanism through the printing module. The rewinding mechanism then rewinds the raw material. During the process of the raw material passing through the printing module, the printing module prints the color marks onto the raw material packaging paper. The printing module mainly includes a frame with an inlet and an outlet. The raw material enters the printing module on the frame through the inlet and is discharged through the outlet.
[0004] However, in order to ensure the precision of packaging bag production, in the actual production process, it is often necessary for operators to use measuring tools to measure the distance between the color marks on the packaging bag to ensure the precision of subsequent cutting and bag making. However, manual measurement is cumbersome and cannot detect the position of each color mark, so there is room for improvement. Utility Model Content
[0005] In order to achieve the technical effect of automatic detection of color marks and ensure the accuracy of color mark printing operation on packaging paper, this application provides a flexible packaging paper color mark printing module.
[0006] The flexible packaging paper color mark printing module provided in this application adopts the following technical solution:
[0007] A flexible packaging paper color mark printing module mainly includes a printing module for printing color marks, the printing module including a frame, the frame including two side plates, and:
[0008] A color mark sensor, adjustablely mounted on any of the side plates, is located at the discharge port of the frame and is used to detect color marks on the packaging paper raw material and output a high-level signal;
[0009] The signal processing module is connected to the signal output terminal of the color mark sensor and is used to receive the high-level signal and calculate the interval duration of the high-level signal occurrence time.
[0010] The controller is connected to the signal output terminal of the signal processing module and is used to output a control signal when the interval exceeds a set time range.
[0011] An alarm module is connected to the signal output terminal of the controller and is used to receive the control signal and issue an alarm signal.
[0012] By adopting the above technical solution, during the actual production process, after the printing module for printing color marks completes printing, the packaging paper is fed out through the discharge port on the frame and passes through the color mark sensor. The color mark sensor senses the color mark printed on the packaging paper and outputs a high-level signal. After receiving the high-level signal, the signal processor calculates the interval between the occurrence of the high-level signal. Since the feeding speed of the printing equipment is stable, the controller determines whether the distance between two adjacent color marks is within the set range based on whether the interval between the occurrence of the high-level signal is within the set range. If the interval between two adjacent color marks is too long or too short, the controller outputs a control signal, and the alarm module alarms after receiving the control signal. The position of each color mark can be detected, eliminating the need for manual measurement of the color mark, ensuring the accuracy of color mark printing, and promptly reminding on-site operators when color mark printing is abnormal.
[0013] Preferably, a through hole is provided through the side plate, and an mounting plate is fixedly installed on the top inner wall of the through hole, the mounting plate extending into the inner side of the side plate;
[0014] The mounting plate is slidably mounted with a sliding seat, and the color mark sensor is fixedly mounted on the sliding seat;
[0015] A connecting plate is fixedly installed on the end of the mounting plate located outside the through hole, and a position adjustment mechanism for adjusting the position of the sliding seat is provided between the connecting plate and the sliding seat.
[0016] By adopting the above technical solution, during the actual printing process, the operator can pre-adjust the positions of the sliding seat and the color mark sensor according to the positions of the packaging paper and the color mark. Since the mounting plate extends out of the side plate through the through hole, when maintenance of the color mark sensor is required, the sliding seat can be moved to the outside of the side plate by adjusting the screw, making it easy for the operator to remove the color mark sensor from the sliding seat.
[0017] Preferably, a slide rail is fixedly installed on the bottom of the mounting plate along the length direction, and a slider is fixedly installed on the top of the sliding seat. The slider has a groove that matches the slide rail, and the slider is slidably installed on the slide rail.
[0018] Limiting protrusions are provided on both sides of the slide rail, and limiting grooves adapted to the two limiting protrusions are respectively opened on the two inner sidewalls opposite to the slide groove. The two limiting protrusions are respectively embedded in the two limiting grooves.
[0019] By adopting the above technical solution, the sliding connection between the sliding seat and the mounting plate can be achieved through the cooperation of the slider and the slide rail; the position of the sliding seat can be restricted by the cooperation and use of the limiting protrusion and the limiting groove, preventing the sliding seat from falling off the mounting plate.
[0020] Preferably, the adjusting mechanism includes a first sleeve, a second sleeve, and an adjusting screw. The first sleeve is fixedly mounted on the connecting plate, and the second sleeve is fixedly mounted on the sliding seat. The first sleeve and the second sleeve are coaxially arranged, and both the first sleeve and the second sleeve have connecting screw holes adapted to the adjusting screw. The adjusting screw is threadedly installed in the first sleeve and the second sleeve.
[0021] By adopting the above technical solution, and by adjusting the length of the adjusting screw extending from the first sleeve, the position of the sliding seat on the slide rail can be changed, thereby achieving the technical effect of adjusting the position of the sliding seat and the color mark sensor.
[0022] Preferably, the end of the adjusting screw extending out of the first sleeve is provided with a four-corner connecting part.
[0023] By adopting the above technical solution and with the four-corner connecting parts, it is convenient for operators to use tools with four-corner connecting sleeves to turn and adjust the lead screw.
[0024] Preferably, the signal processing module includes:
[0025] A timer is used to keep time and output a time signal.
[0026] The microcontroller is connected to the signal output terminals of the timer and color mark sensor, and is used to receive the time signal and the high-level signal and calculate the interval between two adjacent high-level signals.
[0027] By adopting the above technical solution, during the actual testing process, the timer detects the time, and the microcontroller can calculate the interval between the occurrence of two high-level signals based on the timer's detection time. This allows the controller to calculate and compare the interval length between the two color marks based on the interval length and the known feeding speed of the packaging paper.
[0028] Preferably, a first limiting rod, a second limiting rod, and a third limiting rod are fixedly installed between the two side plates. The second limiting rod is located between the first limiting rod and the third limiting rod, directly below the color mark sensor. The height of the second limiting rod is higher than the first limiting rod and the third limiting rod, and the outer surface of the second limiting rod is coated with a white coating.
[0029] By adopting the above technical solution, when the packaging paper passes through the second limiting rod, the second limiting rod can support the packaging paper. At the same time, since the surface of the second limiting rod is coated with a white coating, it can improve the contrast between the color mark and the surrounding area on the transparent packaging paper, thus ensuring the recognition accuracy of the color mark sensor.
[0030] Preferably, the alarm module includes an audible and visual alarm, which is fixedly installed on the outside of the side plate and located beside the through hole.
[0031] By adopting the above technical solution, when the interval length between two color marks calculated by the controller exceeds the set length range, the audible and visual alarm will emit a warning sound and flash a light.
[0032] In summary, the flexible packaging paper color mark printing module of this application has at least the following beneficial technical effects:
[0033] 1. During actual production and processing, after the printing module for printing color marks completes printing, the packaging paper is fed out through the discharge port on the frame and passes through the color mark sensor. The color mark sensor senses the color mark printed on the packaging paper and outputs a high-level signal. After receiving the high-level signal, the signal processor calculates the interval between the occurrence of the high-level signal. Since the feeding speed of the printing equipment is stable, the controller determines whether the distance between two adjacent color marks is within the set range based on whether the interval between the occurrence of the high-level signal is within the set range. If the interval between two adjacent color marks is too long or too short, the controller outputs a control signal. After receiving the control signal, the alarm module alarms. The position of each color mark can be detected, eliminating the need for manual measurement of the color mark, ensuring the accuracy of color mark printing, and promptly reminding on-site operators when color mark printing is abnormal.
[0034] 2. Since the mounting plate extends out of the side plate through the through hole, when the color mark sensor needs maintenance, the sliding seat can be moved to the outside of the side plate by adjusting the screw, making it easy for the operator to remove the color mark sensor from the sliding seat.

[0038] The following is in conjunction with the appendix Figure 1-2 This application will be described in further detail.
[0039] Example
[0040] This application discloses a flexible packaging paper color mark printing module. (Refer to...) Figures 1-2 It mainly includes a printing module for printing color marks, the printing module including a frame, the frame including two side plates 1, and: a color mark sensor 2, which is adjustablely mounted on either side plate 1 and located at the discharge port of the frame, used to detect color marks on the packaging paper raw material and output a high-level signal; a signal processing module, which is connected to the signal output terminal of the color mark sensor 2, used to receive the high-level signal and calculate the interval duration of the high-level signal occurrence time; a controller, which is connected to the signal output terminal of the signal processing module, used to output a control signal when the interval duration exceeds the set duration range; and an alarm module, which is connected to the signal output terminal of the controller, used to receive the control signal and issue an alarm signal.
[0041] During actual production, after the printing module for printing color marks completes printing, the packaging paper is fed out through the discharge port on the frame and passes through the color mark sensor 2. The color mark sensor 2 senses the color mark printed on the packaging paper and outputs a high-level signal. After receiving the high-level signal, the signal processor calculates the interval between the occurrence of the high-level signal. Since the feeding speed of the printing equipment is stable, the controller determines whether the distance between two adjacent color marks is within the set range based on whether the interval between the occurrence of the high-level signal is within the set range. If the interval between two adjacent color marks is too long or too short, the controller outputs a control signal. After receiving the control signal, the alarm module alarms. The position of each color mark can be detected, eliminating the need for manual measurement of the color mark, ensuring the accuracy of color mark printing, and promptly alerting on-site operators when color mark printing is abnormal.
[0042] Reference Figure 1 and Figure 2A through hole 11 is provided on the side plate 1. A mounting plate 12 is fixedly installed on the top inner wall of the through hole 11 and extends into the inner side of the side plate 1. A sliding seat 3 is slidably installed on the mounting plate 12, and the color mark sensor 2 is fixedly installed on the sliding seat 3. A connecting plate 13 is fixedly installed on the end of the mounting plate 12 located outside the through hole 11. A position adjustment mechanism 4 for adjusting the position of the sliding seat 3 is provided between the connecting plate 13 and the sliding seat 3.
[0043] During the actual printing process, the operator can adjust the positions of the sliding seat 3 and the color mark sensor 2 in advance according to the position of the packaging paper and the color mark. Since the mounting plate 12 extends out of the side plate 1 through the through hole 11, when the color mark sensor 2 needs to be maintained, the sliding seat 3 can be moved to the outside of the side plate 1 by adjusting the screw 43, so that the operator can easily remove the color mark sensor 2 from the sliding seat 3.
[0044] In this embodiment, a slide rail 14 is fixedly installed on the bottom of the mounting plate 12 along the length direction, and a slider 15 is fixedly installed on the top of the sliding seat 3. The slider 15 has a groove 151 adapted to the slide rail 14, and the slider 15 is slidably installed on the slide rail 14. Limiting protrusions 141 are provided on both sides of the slide rail 14, and limiting grooves 152 adapted to the two limiting protrusions 141 are respectively provided on the two inner sidewalls opposite to the groove 151. The two limiting protrusions 141 are respectively embedded in the two limiting grooves 152.
[0045] By cooperating with the slider 15 and the slide rail 14, the sliding connection between the sliding seat 3 and the mounting plate 12 can be achieved; by cooperating with the limiting protrusion 141 and the limiting groove 152, the position of the sliding seat 3 can be restricted, preventing the sliding seat 3 from falling off the mounting plate 12.
[0046] Reference Figure 2 The adjusting mechanism includes a first sleeve 41, a second sleeve 42, and an adjusting screw 43. The first sleeve 41 is fixedly installed on the connecting plate 13, and the second sleeve 42 is fixedly installed on the sliding seat 3. The first sleeve 41 and the second sleeve 42 are coaxially arranged, and both the first sleeve 41 and the second sleeve 42 are provided with connecting screw holes adapted to the adjusting screw 43. The adjusting screw 43 is threadedly installed in the first sleeve 41 and the second sleeve 42.
[0047] By adjusting the length of the adjusting screw 43 extending from the first sleeve 41, the position of the sliding seat 3 on the slide rail 14 can be changed, thereby achieving the technical effect of adjusting the position of the sliding seat 3 and the color mark sensor 2.
[0048] Reference Figure 1The end of the adjusting screw 43 extending out of the first sleeve 41 is provided with a four-corner connecting part 44. The four-corner connecting part 44 makes it easy for the operator to turn the adjusting screw 43 with a tool equipped with a four-corner connecting sleeve.
[0049] In this embodiment, the signal processing module includes: a timer for timing and outputting a time signal; and a microcontroller connected to the signal output terminals of the timer and the color mark sensor 2 for receiving the time signal, the high-level signal, and calculating the interval between two adjacent high-level signals.
[0050] During the actual testing process, the timer detects the time, and the microcontroller can calculate the interval between the occurrence of two high-level signals based on the timer's detection time. This allows the controller to calculate and compare the interval length between the two color marks based on the interval length and the known feeding speed of the packaging paper.
[0051] Reference Figure 1 A first limiting rod 16, a second limiting rod 17, and a third limiting rod 18 are fixedly installed between the two side plates 1. The second limiting rod 17 is located between the first limiting rod 16 and the third limiting rod 18. The second limiting rod 17 is located directly below the color mark sensor 2. The height of the second limiting rod 17 is higher than the first limiting rod 16 and the third limiting rod 18, and the surface of the second limiting rod 17 is coated with a white coating.
[0052] When the packaging paper passes the second limiting rod 17, the second limiting rod 17 can support the packaging paper. At the same time, since the surface of the second limiting rod 17 is coated with a white coating, it can improve the contrast between the color mark and the surrounding area on the transparent packaging paper, thus ensuring the recognition accuracy of the color mark sensor 2.
[0053] Reference Figure 1 The alarm module includes an audible and visual alarm 5, which is fixedly installed on the outside of the side plate 1 and located beside the through hole 11. When the interval length between two color marks calculated by the controller exceeds the set length range, the audible and visual alarm 5 emits a warning sound and flashes a light.
[0054] The implementation principle of a flexible packaging paper color mark printing module in this application embodiment is as follows: During the actual production process, after the printing module used to print color marks completes printing, the packaging paper is fed out through the discharge port on the frame and passes through the color mark sensor 2. The color mark sensor 2 senses the color mark printed on the packaging paper and outputs a high-level signal. After receiving the high-level signal, the signal processor calculates the interval of the high-level signal occurrence time. Since the feeding speed of the printing equipment is stable, the controller judges whether the distance between two adjacent color marks is within the set time range based on whether the interval of the high-level signal occurrence is within the set time range. If the interval between two adjacent color marks is too long or too short, the controller outputs a control signal. After receiving the control signal, the alarm module alarms. The position of each color mark can be detected, eliminating the need for manual measurement of the color mark, ensuring the accuracy of color mark printing, and promptly reminding on-site operators when color mark printing is abnormal.
[0055] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
