Abstract
Description
Technical Field
[0001] This utility model relates to the field of printing technology, specifically to a pressure box top cover mechanism and a coding machine for eliminating three-stage coding skew. Background Technology
[0002] In the product packaging process, the labeling of the product's three-phase information is crucial, affecting consumer rights and the company's quality traceability management. Existing laser printing and inspection systems for three-phase information on cardboard boxes suffer from printing misalignment during the inkjet printing process. This is because cardboard boxes have a certain degree of resilience, and the conveyor belt vibrates and shakes during operation. If fluctuations occur during the three-phase printing, it can lead to skewed printing (e.g.,...). Figure 1 As shown in the figure, the product information in the three phases is inconsistent and not effectively integrated with the three-phase identification technology. This makes it impossible to accurately verify and process the three-phase information, which affects the company's production efficiency and brand image. Utility Model Content
[0003] The purpose of this invention is to provide a box-pressing top cover mechanism and a coding machine for eliminating three-stage coding skew. This mechanism adds a top cover for pressing the paper box. During the paper box conveying process, when the paper box passes through the coding area, the top cover will keep the paper box in a fixed position and angle, preventing the paper box from being skewed due to vibration and shaking during the operation of the conveyor belt.
[0004] This utility model is achieved through the following technical solution:
[0005] A pressure box top cover mechanism for eliminating three-phase inkjet printing skew includes:
[0006] A drive assembly, which is mounted above the conveyor belt;
[0007] A clamping assembly includes a top cover for clamping a paper tray, the top cover being connected to the output end of a drive assembly, the drive assembly driving the top cover to move toward the coding area.
[0008] In this solution, the drive assembly is mounted above the conveyor belt, providing power to the entire mechanism and serving as the power source for precise control of the cardboard box. The top cover in the clamping assembly, acting directly on the cardboard box, is connected to the output of the drive assembly and moves towards the coding area under its drive. During cardboard box transport, when the cardboard box enters the coding area, the top cover promptly clamps the box, maintaining it in a fixed position and angle. This effectively overcomes the problem of skewed coding caused by conveyor belt vibration, swaying, and the cardboard box's own resilience in existing technologies, ensuring the accuracy of the coding of the product's three-phase information.
[0009] As a further technical solution for the pressing box top cover mechanism, the driving component includes a synchronous motor and a synchronous belt. The synchronous belt is arranged along the movement direction of the conveyor belt. One end of the synchronous belt is connected to the synchronous motor, and the other end of the synchronous belt is connected to the top cover.
[0010] In this design, a synchronous motor serves as the power source, providing stable and controllable power output to the entire drive assembly. A synchronous belt is positioned along the conveyor belt's direction of movement, connected to the synchronous motor on one side to efficiently transmit its power, and connected to the top cover on the other side, enabling precise movement of the top cover under the belt's influence. The synchronous belt ensures the accuracy and stability of power transmission, preventing abnormal top cover movement due to power fluctuations, which could affect the cardboard box's fixation. Furthermore, its alignment with the conveyor belt and connection to the top cover allows the top cover to follow the conveyor belt's rhythm, precisely pressing against the cardboard box as it enters the coding area. This provides stable control over the cardboard box's position and angle, significantly improving the reliability and accuracy of the top cover mechanism in eliminating three-stage coding skew.
[0011] As a further technical solution for the pressing box top cover mechanism, the movement speed of the synchronous belt is the same as the movement speed of the conveyor belt.
[0012] In this solution, when the speed of the synchronous belt and the conveyor belt are consistent, it ensures that the cardboard box is smoothly acted upon by the pressing mechanism during transport. Firstly, identical speeds prevent displacement, deformation, or shaking of the cardboard box caused by forces acting at different speeds. If the synchronous belt speed is too fast or too slow, the cardboard box may be pulled or squeezed during the pressing process, leading to positional shifts. This compromises the stability of the cardboard box during inkjet printing, making skewed printing difficult to avoid. Secondly, consistent speeds enable coordinated operation, allowing the cardboard box to pass through the printing area at a constant speed as the pressing mechanism moves with the synchronous belt and presses against the cardboard box. This provides stable printing conditions for the inkjet printing components, ensuring accurate and clear printing positions for all three phases of printing.
[0013] As a further technical solution for the pressing box top cover mechanism, the pressing assembly also includes a fixed platform and a connecting column. The fixed platform is connected to the other end of the synchronous belt through the connecting column and moves synchronously with the synchronous belt. The lower end of the fixed platform faces the conveyor belt, and the top cover is connected to the lower end face of the fixed platform.
[0014] In this design, the fixed platform is connected to the synchronous belt via connecting columns, ensuring its synchronized movement with the belt. This stable connection makes power transmission more reliable, preventing disconnection or wobbling. The lower end of the fixed platform faces the conveyor belt, precisely positioning its relative position to the cardboard box, providing a foundation for the stable action of the top cover on the box. The top cover, connected to the lower surface of the fixed platform, relies on the support and transmission of the fixed platform and connecting columns to accurately follow the synchronous belt's movement, always maintaining a suitable position directly above the cardboard box. When the cardboard box passes through the coding area, the top cover stably presses against the box, effectively preventing displacement or angular deviation caused by conveyor belt vibration, wobbling, and its own resilience.
[0015] As a further technical solution for the pressing box top cover mechanism, the pressing assembly also includes an adjusting seat, one end of which is connected to the lower end face of the fixed platform, and the other end of which is connected to the top cover through an adjusting part.
[0016] In this design, one end of the adjusting base is connected to the lower surface of the fixed platform, ensuring a stable installation position. The other end is connected to the top cover via an adjusting mechanism, creating an adjustable connection structure. This allows the top cover to be precisely adjusted according to factors such as the height, thickness, and material characteristics of different cardboard boxes. By adjusting the adjusting mechanism, the relative position between the top cover and the fixed platform can be changed, thereby adjusting the clamping force and contact angle of the top cover on the cardboard box. For thinner or softer cardboard boxes, the clamping force can be appropriately reduced to prevent the cardboard box from being crushed. For taller cardboard boxes, the height of the top cover can be increased accordingly to ensure that the top cover can always effectively clamp the cardboard box. This comprehensively ensures the accurate elimination of the three-phase inkjet printing misalignment problem under various conditions, greatly enhancing the versatility and practicality of the cardboard box pressing top cover mechanism.
[0017] As a further technical solution for the pressing box top cover mechanism, in order to provide a precise, convenient and stable implementation method for the pressing box top cover mechanism, the adjusting seat and the top cover are connected by threads.
[0018] As a further technical solution for the pressure box top cover mechanism, a telescopic motor assembly is provided at the other end of the adjustment seat, and the top cover is connected to the output end of the telescopic motor assembly.
[0019] In this solution, the application of the telescopic motor assembly not only improves the adjustment speed but also significantly enhances the adjustment accuracy. The motor drive enables precise control of the top cover position, ensuring the accuracy of each adjustment and avoiding poor contact between the top cover and the cardboard box caused by manual adjustment errors. This effectively prevents the occurrence of three-phase inkjet printing skew issues and guarantees the quality stability of product packaging inkjet printing.
[0020] As a further technical solution for the box pressing top cover mechanism, the surface of the top cover that contacts the paper box is covered with a flexible cushioning layer.
[0021] In this solution, the flexible buffer layer can protect the cardboard box from indentations, scratches, or damage caused by the pressure of the top cover; it can also buffer the vibration of the conveyor belt and equipment operation, reducing the impact on the cardboard box and lowering the probability of skewed coding; it can also enhance friction to prevent the cardboard box from sliding when it is tightened, ensuring accurate coding position and improving the quality and appearance of product packaging.
[0022] As a further technical solution of the pressing box top cover mechanism, the pressing box top cover mechanism also includes a control device. A detection sensor for detecting the position and conveying status of the paper box is provided between the top cover and the conveyor belt. The detection sensor feeds back the signal to the control device. The control device is electrically connected to the drive assembly and the telescopic motor assembly.
[0023] In this solution, the detection sensor constantly monitors the status of the cardboard box. If any abnormality is detected, it quickly transmits a signal to the control device. Based on a preset program and the received feedback, the control device precisely issues commands to the drive assembly and the telescopic motor assembly. For example, when the cardboard box's position or height changes, the drive assembly adjusts the cardboard box position, and the telescopic motor assembly adjusts the top cover height. This ensures the cardboard box's position and angle are stable within the coding area, preventing skewed coding, reducing manual intervention, and improving production efficiency and coding quality.
[0024] A coding machine includes a conveyor belt, a pressing box top cover mechanism, and a coding assembly. The pressing box top cover mechanism is mounted above the conveyor belt, presses against a paper box on the conveyor belt, and synchronously conveys the paper box to the coding assembly for coding.
[0025] Compared with the prior art, this utility model has the following advantages and beneficial effects:
[0026] 1. By setting up a driving component and a clamping component, this utility model can make the top cover clamp the paper box when the paper box enters the coding area, fix its position and angle, and effectively eliminate the problem of coding skew.
[0027] 2. The drive assembly of this utility model adopts a synchronous motor and a synchronous belt, and the synchronous belt and the conveyor belt have the same speed, which ensures the stable and synchronous movement of the top cover and the carton. This ensures that the top cover of the carton is accurately positioned in the horizontal and vertical directions and prevents it from tilting.
[0028] 3. The fixing platform, connecting column and adjusting seat in the clamping assembly of this utility model not only enhance the overall stability, but also allow the top cover height to be adjusted according to the cardboard box specifications, thus improving versatility;
[0029] 4. The adjusting seat of this utility model is connected to the top cover by a thread or by a telescopic motor assembly, providing a precise and convenient way to adjust the height. The flexible buffer layer on the surface of the top cover protects the cardboard box while increasing friction and reducing the impact of vibration. Attached Figure Description

[0037] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings. The illustrative embodiments and descriptions of this utility model are only used to explain this utility model and are not intended to limit this utility model.
[0038] Example 1
[0039] This embodiment 1 provides a pressure box top cover mechanism to eliminate the skewness of the three-stage inkjet printing, such as Figures 1-4 As shown, it includes a drive assembly and a clamping assembly;
[0040] Please refer to Figures 1-4 As shown, the drive assembly is mounted above the conveyor belt, providing power support for the entire mechanism. The drive assembly includes a synchronous motor 1 and a synchronous belt 2. The synchronous motor 1 serves as the power source, providing stable and controllable power output to the entire drive assembly. The synchronous belt 2 is arranged along the movement direction of the conveyor belt. One end of the synchronous belt 2 is connected to the synchronous motor 1, so that the movement speed of the synchronous belt 2 is the same as that of the conveyor belt. The other end of the synchronous belt 2 is connected to the top cover 3, so that the top cover 3 can follow the rhythm of the conveyor belt and precisely press the paper box when it enters the coding area, achieving stable control of the position and angle of the paper box. This greatly improves the reliability and accuracy of the top cover mechanism in eliminating the three-stage coding skew.
[0041] Please refer to the following: Figures 1-4As shown, the clamping assembly includes the top cover 3, the fixed platform 4, the connecting column 5, and the adjusting seat 6 used to clamp the cardboard box. The top cover 3 is the component that directly acts on the cardboard box. The fixed platform 4 is connected to the other end of the synchronous belt 2 through the connecting column 5 and moves synchronously with the synchronous belt 2. The lower end of the fixed platform 4 faces the conveyor belt. One end of the adjusting seat 6 is connected to the lower end face of the fixed platform 4, and the other end of the adjusting seat 6 is connected to the top cover 3 through the adjusting part. An adjustable connection structure can be constructed through the adjusting part, so that the top cover 3 can be precisely adjusted according to factors such as the height, thickness, and material characteristics of different cardboard boxes.
[0042] Specifically, the adjusting seat 6 and the top cover 3 are connected by threads. By rotating the top cover 3 and the adjusting seat 6, the height of the top cover can be adjusted with a very small stroke change. This precise adjustment can meet the subtle differences in the height of different paper boxes, ensuring that the top cover 3 and the paper box maintain just the right contact. This effectively tightens the paper box to prevent it from shaking during the coding process, and also prevents the paper box from being damaged due to excessive pressure.
[0043] In summary, during the paper box conveying process, when the paper box passes through the coding area, the top cover 3 will keep the paper box in a fixed position and angle. The paper box is pushed forward synchronously by the conveyor belt and the top cover 3, which can ensure the accurate position of the top cover of the paper box in the horizontal and vertical directions and prevent skewing.
[0044] Example 2
[0045] This embodiment 2 provides a pressure box top cover mechanism to eliminate the skewness of the three-stage inkjet printing, such as Figures 1-4 As shown, it includes a drive assembly, a clamping assembly, and a control device;
[0046] Please refer to Figures 1-4 As shown, the drive assembly is mounted above the conveyor belt, providing power support for the entire mechanism. The drive assembly includes a synchronous motor 1 and a synchronous belt 2. The synchronous motor 1 serves as the power source, providing stable and controllable power output to the entire drive assembly. The synchronous belt 2 is arranged along the movement direction of the conveyor belt. One end of the synchronous belt 2 is connected to the synchronous motor 1, so that the movement speed of the synchronous belt 2 is the same as that of the conveyor belt. The other end of the synchronous belt 2 is connected to the top cover 3, so that the top cover 3 can follow the rhythm of the conveyor belt and precisely press the paper box when it enters the coding area, achieving stable control of the position and angle of the paper box. This greatly improves the reliability and accuracy of the top cover mechanism in eliminating the three-stage coding skew.
[0047] Please refer to the following: Figures 1-4As shown, the clamping assembly includes the top cover 3, the fixing platform 4, the connecting column 5, and the adjusting seat 6 for clamping the cardboard box. The top cover 3 acts directly on the cardboard box, while the fixing platform 4 is connected to the other end of the synchronous belt 2 via the connecting column 5 and moves synchronously with the synchronous belt 2. The lower end of the fixing platform 4 faces the conveyor belt. One end of the adjusting seat 6 is connected to the lower end face of the fixing platform 4, and the other end of the adjusting seat 6 is connected to the top cover 3 via the adjusting part. An adjustable connection structure can be constructed through the adjusting part, so that the top cover 3 can be precisely adjusted according to factors such as the height, thickness, and material characteristics of different cardboard boxes. In some embodiments, in order to avoid indentations, scratches, or damage caused by the pressure of the top cover 3, the surface of the top cover 3 that contacts the cardboard box is covered with a flexible buffer layer, which is made of rubber or silicone.
[0048] Specifically, the other end of the aforementioned adjustment seat 6 is equipped with a telescopic motor assembly, which is a common electric push rod or cylinder or other device with reciprocating extension motion. The top cover 3 is connected to the output end of the telescopic motor assembly. The motor drive can achieve precise control of the top cover position, ensuring the accuracy of each adjustment and avoiding poor contact between the top cover and the cardboard box caused by manual adjustment errors, thereby effectively preventing the occurrence of the three-phase inkjet printing skew problem.
[0049] Meanwhile, a detection sensor is installed between the top cover 3 and the conveyor belt to detect the position and conveying status of the cardboard box. The detection sensor feeds back the signal to the control device, which is electrically connected to the synchronous motor 1 and the telescopic motor assembly. The detection sensor monitors the status of the cardboard box at all times. Once an abnormality is detected, it quickly transmits the signal to the control device. Based on the preset program and the received feedback, the control device accurately issues instructions to the drive assembly and the telescopic motor assembly. For example, when the position or height of the cardboard box changes, it controls the drive assembly to adjust the position of the cardboard box and the telescopic motor assembly to adjust the height of the top cover, thereby ensuring that the position and angle of the cardboard box in the coding area are stable, avoiding skewed coding in the three phases, reducing manual intervention, and improving production efficiency and coding quality.

[0052] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of this utility model. It should be understood that the above description is only a specific embodiment of this utility model and is not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
