Description

Technical Field

[0001] This utility model relates to the field of inkjet printing equipment technology, and more specifically, to an inkjet printing device and a conveying device. Background Technology

[0002] In the packaging industry, especially on large-scale production lines in the food sector, packaging bags serve as a crucial component carrying materials and also bear the responsibility of conveying product information. Traditional inkjet printers have high requirements for the flatness of the packaging bag surface, as uneven bags directly affect the clarity and accuracy of the coding, thus impacting the accuracy of product information transmission. For example, after products such as milk powder are filled into packaging bags, the bags may develop wrinkles, bulges, or other shape changes. These shape changes can interfere with the normal operation of the inkjet printer, leading to problems such as blurred or interrupted coding, and misaligned positions, affecting the readability and accuracy of the product information.

[0003] In related technologies, manual intervention is used to improve the coding effect. This involves workers manually shaping each packaging bag before coding to correct its shape. However, this method increases production costs and reduces production efficiency.

[0004] Therefore, the manual reshaping of packaging bags in related technologies increases production costs. Utility Model Content

[0005] The main purpose of this utility model is to provide a coding device and a conveying device to solve the problem in related technologies where manual shaping of packaging bags increases production costs.

[0006] To achieve the above objectives, according to one aspect of the present invention, a coding device is provided, comprising: a first support; a second support disposed opposite to the first support; a first telescopic member including a first cylinder and a first telescopic rod, the first cylinder being disposed on the first support and the first telescopic rod being telescopically disposed within the first cylinder; a coding device disposed on the first support; and a first clamping plate connected to the first telescopic rod, wherein the first telescopic rod extends to give the first clamping plate on the first telescopic rod a first shaping position close to the second support, and the first telescopic rod retracts to give the first clamping plate on the first telescopic rod a first clearance position away from the second support; wherein the first clamping plate is provided with a clearance opening for the coding device.

[0007] Furthermore, the coding equipment also includes a mounting plate fixedly connected to the first clamping plate, and the coding device is mounted on the mounting plate.

[0008] Furthermore, the first clamping plate is movably arranged along the first direction, and the inkjet printing device includes a first driving member, a transmission structure, and an inkjet printing head arranged on the mounting plate. The first driving member drives the inkjet printing head to move along the second direction through the transmission structure, and the first direction forms an angle with the second direction.

[0009] Furthermore, the first driving component is a drive motor, and the transmission structure includes a slide rail mounted on the mounting plate and a slider that guides and cooperates with the slide rail. The spray nozzle is connected to the slider. The motor shaft of the drive motor is provided with an external thread, and the slider is provided with a threaded hole that can cooperate with the external thread.

[0010] Furthermore, the coding device also includes a first anti-slip pad disposed on the side of the first clamping plate facing the second bracket.

[0011] Furthermore, the coding device also includes a second clamping plate and a second telescopic component. The second telescopic component includes a second cylinder and a second telescopic rod. The second cylinder is mounted on a second bracket, and the second telescopic rod is telescopically mounted inside the second cylinder. The second clamping plate is connected to the second telescopic rod, and the second telescopic rod extends and retracts to give the second clamping plate a second shaping position close to the first clamping plate and a second clearance position away from the first clamping plate.

[0012] Furthermore, the coding device also includes a second anti-slip pad disposed on the side of the second clamp facing the first bracket.

[0013] According to another aspect of the present invention, a conveying device is provided, including a conveyor belt and a coding device, wherein the coding device is the aforementioned coding device, and a first bracket and a second bracket are respectively disposed on both sides of the conveyor belt.

[0014] Furthermore, the conveying equipment also includes a detection component and a controller.

[0015] Furthermore, the conveying equipment also includes a second drive unit for driving the conveyor belt, and the controller is connected to the second drive unit for control.

[0016] The coding device, utilizing the technical solution of this utility model, includes: a first support, a second support, a first telescopic component, a coding device, and a first clamping plate. The second support is arranged opposite to the first support. The first telescopic component includes a first cylinder and a first telescopic rod. The first cylinder is mounted on the first support, and the first telescopic rod is telescopically mounted within the first cylinder. The coding device is mounted on the first support. The first clamping plate is connected to the first telescopic rod. The first telescopic rod extends to give the first clamping plate a first shaping position close to the second support, and retracts to give the first clamping plate a first clearance position away from the second support. The first clamping plate has a clearance opening for the coding device. Thus, the extension and retraction of the first telescopic rod within the first cylinder by the first telescopic component moves the first clamping plate, allowing it to switch to the first shaping position. At this position, the first clamping plate and the second support together clamp the packaging bag, smoothing out wrinkles and bulges on the bag surface through uniform pressure. This improves the shape of the packaging bag before coding, enhances the coding effect, reduces human intervention, and lowers labor and production costs. The first telescopic rod moves the first clamping plate to a first clearance position. At this position, the first clamping plate is away from the second support, allowing the packaging bag to be moved or removed between the first clamping plate and the second support for subsequent processes. Furthermore, the first clamping plate is equipped with a clearance opening to avoid the coding device, ensuring that the first clamping plate does not obstruct the coding operation while shaping the packaging bag. This achieves simultaneous shaping and coding, further improving the coding effect and making the coding clearer and more accurate. Through these features, the coding equipment can accurately control the shape of the packaging bag during the coding process, avoiding coding deviation and blurred text, improving coding quality and production efficiency, and reducing production costs. Therefore, the technical solution of this application effectively solves the problem in related technologies where manual shaping of packaging bags increases production costs.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present utility model or its application or use. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0033] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0034] Unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps described in these embodiments do not limit the scope of this invention. It should also be understood that, for ease of description, the dimensions of the various parts shown in the drawings are not drawn to actual scale. Techniques, methods, and devices known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and devices should be considered part of the specification. In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following drawings denote similar items; therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings.

[0035] In this embodiment, as Figures 1 to 3 As shown, the coding equipment includes: a first bracket 11, a second bracket 12, a first telescopic member 20, a coding device, and a first clamping plate 60. The second bracket 12 is disposed opposite to the first bracket 11. The first telescopic member 20 includes a first cylinder 21 and a first telescopic rod 22. The first cylinder 21 is disposed on the first bracket 11, and the first telescopic rod 22 is telescopically disposed within the first cylinder 21. The coding device is disposed on the first bracket 11. The first clamping plate 60 is connected to the first telescopic rod 22. The first telescopic rod 22 extends so that the first clamping plate 60 on the first telescopic rod 22 has a first shaping position close to the second bracket 12, and the first telescopic rod 22 retracts so that the first clamping plate 60 on the first telescopic rod 22 has a first clearance position away from the second bracket 12. The first clamping plate 60 is provided with a clearance opening 61 for the coding device.

[0036] Thus, the extension and retraction of the first telescopic rod 22 within the first cylinder 21 via the first telescopic member 20 can move the first clamping plate 60, allowing it to switch to the first shaping position. At this position, the first clamping plate 60 and the second support 12 jointly hold the packaging bag, smoothing out wrinkles and bulges on the bag surface through uniform pressure. This improves the bag's shape before coding, enhances the coding effect, and reduces human intervention, lowering labor and production costs. The first telescopic rod 22 then moves the first clamping plate 60 to the first clearance position, allowing it to move away from the second support 12, enabling the packaging bag to be removed or taken out between the first clamping plate 60 and the second support 12 for subsequent processes. Furthermore, the first clamping plate 60 is equipped with a clearance opening 61 to avoid the coding device, ensuring that the first clamping plate 60 does not obstruct the coding operation while shaping the packaging bag, achieving simultaneous shaping and coding operations, further improving the coding effect and making the coding clearer and more accurate. By implementing the above settings, the coding equipment can accurately control the shape of the packaging bag during the coding process, avoiding issues such as coding offset and blurred text, thus improving coding quality and production efficiency while reducing production costs. Therefore, the technical solution of this embodiment effectively solves the problem in related technologies where manually shaping the packaging bag increases production costs.

[0037] like Figures 1 to 3 As shown, the coding equipment also includes a mounting plate 70 fixedly connected to the first clamping plate 60, and the coding device is mounted on the mounting plate 70. In this way, the mounting plate 70 connects the coding device to the first clamping plate 60, allowing the coding device to move with the first clamping plate 60. The coding device adjusts its posture synchronously with the first clamping plate 60, reducing the distance between the coding device and the packaging bag, thereby improving coding quality, ensuring accurate positioning during coding operations, and placing the coding device in the optimal printing position before coding begins.

[0038] like Figures 1 to 3As shown, the first clamping plate 60 is movably arranged along a first direction. The coding device includes a first driving member 30, a transmission structure 40, and a coding head 50, all mounted on a mounting plate 70. The first driving member 30 drives the coding head 50 to move along a second direction via the transmission structure 40, with the first and second directions forming an angle. This arrangement allows the first driving member 30 to precisely drive the coding head 50 through the transmission structure 40, ensuring that the coding head 50 moves along a preset coding direction and performs accurate coding. The combination of the driving member and the transmission structure 40 enables stable and controllable movement of the coding head 50 during the coding process, improving the automation level of the coding equipment and reducing labor and production costs. Furthermore, the angle between the first and second directions allows the movement direction of the first clamping plate 60 to be offset from the movement direction of the coding head 50, facilitating the coding operation of the coding head 50.

[0039] In this embodiment, the first driving component 30 is a Leadshine stepper motor, model CL57C 2.0 closed-loop stepper. The inkjet header 50 is model Videojet 1510. The moving speed of the inkjet header 50 is four millimeters per second. After the inkjet printing is completed, the first driving component 30 drives the inkjet header 50 back to its origin. The first direction is perpendicular to the second direction. The first direction is the width direction of the conveyor belt 100, and the second direction is the conveying direction of the conveyor belt 100.

[0040] like Figures 1 to 3 As shown, the first driving component 30 is a drive motor. The transmission structure 40 includes a slide rail 41 mounted on the mounting plate 70 and a slider 42 that guides and engages with the slide rail 41. The inkjet header 50 is connected to the slider 42. The motor shaft of the drive motor has an external thread, and the slider 42 has a threaded hole that engages with the external thread. The inkjet header 50 is mounted on the mounting plate 70 through the guiding engagement structure of the slider 42 and the slide rail 41, ensuring the precise positioning and stable operation of the inkjet header 50 during the coding process. The external thread on the shaft of the drive motor forms a threaded engagement with the threaded hole on the slider 42. This transmission structure 40 enables precise linear movement of the inkjet header 50, allowing the coding operation to proceed smoothly along a preset trajectory, effectively avoiding coding quality fluctuations caused by the unstable position of the inkjet header 50. The above structure is simple and easy to manufacture and assemble.

[0041] In other embodiments, the transmission structure 40 may employ synchronous belt or chain drive to adapt to different production environments and speed requirements.

[0042] like Figures 1 to 3As shown, the coding equipment also includes a first anti-slip pad 62 disposed on the side of the first clamping plate 60 facing the second support 12. The first anti-slip pad 62 increases the friction between the packaging bag and the first clamping plate 60 during the clamping and shaping process, effectively preventing the packaging bag from shifting position due to sliding during coding, ensuring the stability of the packaging bag during coding, and ensuring accurate positioning of the coded text. This reduces coding failures caused by packaging bag slippage, thereby reducing the number of production line downtimes and the need for manual intervention due to coding anomalies, and improving production efficiency and automation levels.

[0043] In this embodiment, the specific material and thickness of the first anti-slip mat 62 need to be selected based on the actual packaging bag material and production line environment to achieve the best anti-slip effect. Preferably, the first anti-slip mat 62 is made of rubber material.

[0044] like Figures 1 to 3 As shown, the coding equipment also includes a second clamping plate 80 and a second telescopic component 90. The second telescopic component 90 includes a second cylinder 91 and a second telescopic rod 92. The second cylinder 91 is mounted on the second bracket 12, and the second telescopic rod 92 is telescopically mounted within the second cylinder 91. The second clamping plate 80 is connected to the second telescopic rod 92. The telescopic rod 92 extends and retracts to give the second clamping plate 80 a second shaping position close to the first clamping plate 60 and a second clearance position away from the first clamping plate 60. Thus, by extending and retracting the second telescopic rod 92 within the second cylinder 91, the second clamping plate 80 can be moved, allowing it to switch to the second shaping position. At this position, the first clamping plate 60 and the second clamping plate 80 jointly clamp the packaging bag, smoothing out wrinkles and bulges on the surface of the packaging bag through uniform pressure. This improves the shape of the packaging bag before coding, enhances the coding effect, reduces human intervention, and lowers labor and production costs. The second telescopic rod 92 drives the second clamping plate 80 to switch to the second clearance position. At this time, the second clamping plate 80 can move away from the first clamping plate 60, so that the packaging bag can be moved out or removed between the first clamping plate 60 and the second clamping plate 80, facilitating subsequent processes. The design of the second clamping plate 80 and the second telescopic component 90 improves the shaping efficiency and effect of the coding equipment on the packaging bag, thereby improving the coding quality.

[0045] In this embodiment, both the first telescopic member 20 and the second telescopic member 90 are preferably telescopic cylinders, model SC63×50.

[0046] like Figures 1 to 3As shown, the coding equipment also includes a second anti-slip pad 81 disposed on the side of the second clamping plate 80 facing the first support 11. The second anti-slip pad 81 increases the friction between the packaging bag and the second clamping plate 80 during the clamping and shaping process, effectively preventing the packaging bag from shifting position due to sliding during coding, ensuring the stability of the packaging bag during coding, and ensuring accurate positioning of the coded text. This reduces coding failures caused by packaging bag slippage, thereby reducing the number of production line downtimes and the need for manual intervention due to coding anomalies, and improving production efficiency and automation levels.

[0047] This application also provides a conveying device, which includes a conveyor belt 100 and a coding device, wherein the coding device is the aforementioned coding device, and a first bracket 11 and a second bracket 12 are respectively disposed on both sides of the conveyor belt 100. Since the aforementioned coding device can solve the problem in related technologies where the shape of packaging bags is corrected manually, increasing production costs, the conveying device with this coding device can solve the same technical problem. Furthermore, by integrating the coding device onto the conveyor belt 100, automatic shaping and automatic coding of packaging bags during the transmission process are achieved, improving production efficiency and reducing production costs.

[0048] Furthermore, the conveying equipment also includes a detection element and a controller. The detection element is signal-connected to the controller, and the controller is control-connected to the first telescopic member 20. The detection element is positioned upstream of the inkjet printer. Thus, when a packaged bag is conveyed by the conveyor belt 100 to the detection element, the detection element can identify it and send a signal to the controller. The controller then controls the first telescopic member 20 to activate, using the first clamping plate 60 to clamp and shape the packaged bag. Through the detection element and controller, the passage of the packaged bag can be automatically detected, and the bag can be clamped and shaped, improving the automation level of the conveying equipment, increasing production efficiency, and reducing production costs.

[0049] In this embodiment, the extension time of the first telescopic member 20 and the second telescopic member 90 is controlled by the controller to control the clamping time of the packaging bag. In this embodiment, the clamping time is four seconds. The detection element is preferably a photoelectric sensor. The photoelectric sensor has a light source emitter that can emit a beam of light, usually infrared or visible light. The photoelectric sensor also includes a light receiver, which can receive the complete beam of light when the light is not blocked. Once the packaging bag passes through the photoelectric sensor area and blocks or reflects the light, the amount of light received by the receiver will change. The circuit inside the photoelectric sensor monitors the change in the amount of light received by the receiver. When the detected change in the amount of light exceeds a preset threshold, the photoelectric sensor converts it into an electrical signal and outputs this electrical signal to the controller. After receiving the signal from the photoelectric sensor, the controller can perform corresponding operations based on this signal. The electrical signal generated by the photoelectric sensor is sent to the controller through the input port. The controller determines whether the packaging bag is in place based on the electrical signal, and then controls the first telescopic member 20 and the second telescopic member 90 accordingly based on the preset control logic. Further, the conveying device also includes a second drive unit for driving the conveyor belt 100, and the controller is connected to the second drive unit. In this way, when the packaging bag is conveyed to the detection unit by the conveyor belt 100, the detection unit can identify it and send a signal to the controller. The controller then controls the second drive unit to decelerate the conveyor belt 100 and bring it to a smooth stop, so that the packaging bag can remain stationary at the inkjet printer, facilitating subsequent inkjet printing operations. This setup ensures that the packaging bag remains stationary during inkjet printing, reducing interference from the conveyor belt 100 and minimizing changes in the bag's shape during printing, thereby improving inkjet printing quality.

[0050] In this embodiment, the second driving component is preferably a drive motor. The controller sends electrical signals to the motor driver of the drive motor through its output port. The motor driver is an electronic device located between the controller and the drive motor. The motor driver amplifies the weak electrical signals from the controller and converts them into a strong current sufficient to drive the drive motor. After receiving the control signals from the controller, the motor driver analyzes these signals and converts them into appropriate voltage and current waveforms, which are then supplied to the drive motor.

[0051] In this embodiment, the controller is preferably a PLC controller, specifically a Siemens S7-1200. The coding device also includes a coding machine, with the inkjet terminal 50 serving as the actuator. The PLC controller sends coding signals to the coding machine, which completes the coding according to preset parameters: font: Arial, font size: 12, spacing: 2mm. The conveying equipment also includes a photoelectric sensor located downstream of the coding machine, used to detect the coded packaging bag. After coding is completed, the coding machine sends a "coding complete" signal to the coding detection system. The system records the current coding and checks for "no code" or "duplicate code." If an anomaly is detected, such as no coding complete signal or duplicate coding, the PLC controller immediately triggers an alarm and sends a stop command, controlling the second drive to stop the production line. If the detection is normal, the PLC controller sends a "next code" command to the coding machine, preparing to receive the next packaging bag. Simultaneously, the second drive restarts, conveying the coded packaging bag to the next stage. The above settings enable real-time communication between the coding system and the production line. When coding anomalies occur, such as printhead blockage or no coding, a line stop alarm can be triggered promptly, preventing defective products from entering subsequent stages and reducing rework costs and product loss. For specific coding detection methods, please refer to the document with authorization announcement number CN117950073B.

[0052] In this embodiment, the first clamping plate 60 clamps the packaging bag for 0.5 seconds, after which the second drive component stops, ensuring the packaging bag remains completely still and preventing it from tilting. During this process, the first clamping plate 60 smooths out the surface wrinkles of the packaging bag through uniform force, achieving a shaping effect. In this embodiment, the inkjet printer's inkjet parameters can be switched with one click. Multiple inkjet parameter templates are preset in the control system's human-machine interface, such as the inkjet font, size, and content corresponding to different product specifications. Operators can switch between them with one click according to production needs, eliminating the need for manual adjustments and reducing parameter setting time and error rates. The system automatically generates logs for each operator operation and inkjet information alarm. Operators can find problems in the logs after an issue occurs. New data is stored in the system operation log, automatically recording the occurrence time and corresponding product batch of inkjet abnormal events (such as no code, duplicate code, inkjet offset); the data can be viewed through an industrial control computer.

[0053] Taking a 12-hour production line operation as an example, before installing the inkjet printer of this embodiment, there were approximately 30 short-term shutdowns due to inkjet printing abnormalities, requiring manual adjustment and handling. Each short-term shutdown took an average of 10 minutes, resulting in a cumulative production time impact of 300 minutes. After installing the inkjet printer of this embodiment, the number of short-term shutdowns was reduced to ≤2, with a cumulative production time impact of ≤20 minutes, increasing production efficiency by approximately 8.3%. Before installing the inkjet printer of this embodiment, two people were required to be dedicated to inkjet printing detection, abnormality handling, and parameter adjustment for 12 hours. After installing the inkjet printer of this embodiment, only one person is needed for regular inspections (twice a day, 30 minutes each time), reducing the workload by approximately 10.5 hours per person per shift and lowering labor costs. Before installing the inkjet printer of this embodiment, the amount of products rejected due to inkjet printing defects was approximately 15 bags / 12 hours (each bag of powder weighs 25kg). Calculated at a cost of 10 yuan per kilogram of powder, the loss in 12 hours was approximately 3750 yuan. After installing the coding equipment of this embodiment, the rejection rate is reduced to ≤1 bag / 12 hours, with a loss of ≤250 yuan per 12 hours. This translates to a reduction of 7,000 yuan in losses per day (24 hours) and 2.1 million yuan in savings per year (based on 300 working days). Through the abnormal data recording and analysis function, technicians can quickly locate fault points (such as frequent duplicate codes within a certain time period, indicating communication delays in the coding system), shortening maintenance time by approximately 60% and reducing downtime losses due to maintenance.

[0054] The inventor applied the above-mentioned technical solution to a standard 25kg bulk packaging bag. The telescopic cylinder stroke was 50mm, the preset clamping pressure was 0.6MPa, the clamping time was 4 seconds, and the shaping delay time was 0.5 seconds. The inkjet printer's movement speed was 4mm / s, the movement distance was 160mm, the inkjet font was Arial, the font size was 12, and the inkjet content was "product batch + production date + shelf life + raw material code + tonnage + number of bags", with a printing spacing of 2mm. Operational results: Within 12 hours, the inkjet printing pass rate was ≥99.8%, there was no inkjet offset due to bag deformation, and the number of abnormal short stops was ≤1.

[0055] The inventor applied the above technical solution to a 15kg thin-pack packaging bag. The stroke of the telescopic cylinder is 40mm (adjustable by replacing the telescopic cylinder), the clamping time is 3.5 seconds, and the shaping delay time is 0.5 seconds. The inkjet printer's movement speed is 3.5mm / s, the movement distance is 140mm (adapted to the length of the thin bag), the inkjet font is Arial, the font size is 10, the inkjet content is consistent with the above, and the inkjet spacing is 1.8mm. Operational results: Within 12 hours, the inkjet printing pass rate is ≥99.7%, there are no powder bag breaks, and the number of abnormal short stops is ≤1.

They are only for the convenience of describing this utility model and simplifying the description. Unless otherwise stated, these directional terms 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 therefore should not be construed as a limitation on the scope of protection of this utility model. The directional terms "inner" and "outer" refer to the inner and outer contours of each component itself.

[0057] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures.
