Description

Technical Field

[0001] This utility model relates to the field of batch inkjet printing technology for paper tubes, and in particular to an online batch number printing platform for paper tubes. Background Technology

[0002] During the tape production process, paper tubes must be labeled with the same production batch number as the tape products to ensure product traceability. Currently, the paper tube production line uses a batch number printing platform, which includes a paper tube placement table and a matching inkjet printer or printing press.

[0003] However, existing platforms are prone to misalignment between the paper tube and the printhead, resulting in misaligned or blurry batch numbers, which not only affects subsequent tracking but also reduces tape production efficiency. Utility Model Content

[0004] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0005] To address the aforementioned problems, this utility model provides the following technical solution:

[0006] A batch number printing platform on a paper tube line includes a running platform. The running platform includes a roller and a belt sleeved on the roller. The surface of the belt is provided with a number of partitions at equal intervals. The spacing between adjacent partitions is consistent. The cross-section of the partition is trapezoidal. Its two sides gradually taper from the belt connection to the top, and the sides are uniformly concave inward to form an arc-shaped concave surface.

[0007] Preferably, the belt has a protrusion, and the bottom of the spacer bar is in contact with the outer surface of the protrusion.

[0008] Preferably, the two sides of the spacer are a first side and a second side, and the first side and the second side are mirror-symmetrical about the central axis of the spacer.

[0009] Preferably, the center distance between the center axes of adjacent spacers remains consistent.

[0010] Preferably, the ratio of the bottom to the top of the spacer is 6:1.

[0011] Preferably, the ratio of the bottom of the spacer to the center axis distance is 2:1.

[0012] Preferably, the number of rollers is two, and a support block is provided in the belt space between the two rollers.

[0013] Preferably, the two ends of the support block extend close to the two rollers, and the outer surface of the support block is in contact with the belt.

[0014] Preferably, the support block is provided with a baffle plate, the baffle plate being close to one end of the belt, and the outer surface of the baffle plate being close to one end of the spacer.

[0015] The beneficial effects of this utility model are: through the precise cooperation of the equally spaced trapezoidal partitions and the step-by-step drive of the motor, the paper tube is automatically aligned with the inkjet nozzle each time it stops, thereby reducing the error in batch number printing;

[0016] The design of the fully fitted arc-shaped concave surface of the partition strip with the outer wall of the paper tube prevents rolling deviation during high-speed transportation and ensures printing stability. The narrow top trapezoidal cross section of 6:1 and the compact wheelbase setting of 2:1 increase the loading capacity of the paper tube under the same belt length, significantly improving production efficiency.

[0025] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0026] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0027] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0028] Example

[0029] Reference Figures 1 to 5 This embodiment of the present invention provides a batch number printing platform on a paper tube line, including a running platform 100. The running platform 100 includes a roller 101 and a belt 104 sleeved on the roller 101. A plurality of spacers 200 are evenly spaced on the surface of the belt 104, and the spacing between adjacent spacers 200 is consistent. The cross-section of the spacer 200 is trapezoidal, and its two sides gradually taper from the connection of the belt 104 to the top, and the sides are uniformly concave inward to form an arc-shaped concave surface.

[0030] Specifically, the belt 104 is fitted with two rollers 101, one of which is connected to the motor shaft, allowing the belt 104 to rotate under the drive of the roller 101. Multiple spacers 200 are installed on the belt 104, and the paper tube 300 is supported by the gap between the two spacers. By distributing the spacers 200 at equal intervals on the surface of the belt 104, the paper tube 300 can be aligned with the inkjet printer head every time the motor drives the belt 104, achieving a precise point-to-point printing effect. The specific process can be referred to as follows.

[0031] Stepper motor or servo motor:

[0032] Step angle: Select the rotation angle of the motor per step to ensure that the belt 104 moves exactly one bar spacing (L).

[0033] Calculation formula: The belt travel distance corresponding to each step of the motor = circumference of roller 101 / number of steps per motor revolution × reduction ratio;

[0034] Adjust the reduction ratio or motor microstepping so that each motor step equals a 200mm spacing (L) between the bars.

[0035] Open-loop control (low-cost solution):

[0036] The motor runs at a fixed number of steps (e.g., 100 steps per trigger), requiring no sensors.

[0037] Suitable for low-speed, low-precision scenarios (±0.5mm);

[0038] Motor pulse signal directly triggers inkjet printing:

[0039] After the motor completes a set number of steps (i.e., moves one spacing between bars), the PLC / controller sends a coding signal; no additional sensors are required, reducing complexity.

[0040] It is worth mentioning that, under the same specification belt 104, the cross section of the spacer 200 is trapezoidal. The structure of its two sides gradually narrowing from the connection of the belt 104 to the top is conducive to increasing the number of spacer spacings, which can increase the number of paper tubes 300 placed. The side of the spacer 200 is uniformly concave inward to form an arc-shaped concave surface. The arc-shaped side is in contact with the outer surface of the paper tube 300, which can maintain the stability of the paper tube 300 when the belt 104 moves and stops.

[0041] Furthermore, the belt 104 is constructed with protrusions 105, and the bottom of the spacer 200 is in contact with the outer surface of the protrusions 105. Due to the material properties of the belt 104, the protrusions 105 constructed on the belt 104 have a certain degree of toughness. When the spacer passes through the roller 101, the micro-stretching of the protrusions 105 ensures a stable connection between the bottom of the spacer 200 and the protrusions 105 of the belt 104 and improves the service life of the spacer 200 on the belt 104.

[0042] Furthermore, the two sides of the spacer 200 are the first side 202 and the second side 203, respectively. The first side 202 and the second side 203 are mirror-symmetrical through the central axis 201 of the spacer 200. The completely symmetrical sides of the spacer 200 can ensure that the surfaces of the paper tube 300 in contact with the spacer 200 are symmetrical and the same, thereby improving the stability and reliability of the paper tube 300 in transport under the support of the spacer 200.

[0043] Furthermore, the center axis distance 204 between the center axes 201 of adjacent spacers 200 remains consistent.

[0044] Furthermore, the ratio of the bottom to the top of the spacer 200 is 6:1, so as to reduce the width of the spacer 200 and make the spacer 200 a trapezoid with a smaller top, thereby increasing the number of gaps between the spacers 200, so that the belt 104 of the same length can transport more paper tubes 300.

[0045] Furthermore, the ratio of the bottom of the spacer 200 to the center axis distance 204 is 2:1, which is consistent with increasing the amount of spacing between the spacers 200 so that the belt 104 of the same length can transport more paper tubes 300.

[0046] Furthermore, there are two rollers 101, and a support block 102 is provided in the space of the belt 104 between the two rollers 101. Furthermore, the two ends of the support block 102 extend to near the two rollers 101, and the outer surface of the support block 102 is in contact with the belt 104. By adding the support block 102 between the two rollers 101 of the belt 104 to support the belt 104, the paper tube 300 moves in a plane during transportation, thereby improving the stability of the paper tube 300 transportation.

[0047] Furthermore, the support block 102 is provided with a baffle 103. The baffle 103 is close to one end of the belt 104, and the outer surface of the baffle 103 is close to one end of the spacer 200. The baffle 103 and the spraying terminal are located on one side of the operating platform 100. By placing the paper tube 300 between the spacers 200 and pressing one end of the paper tube 300 against the baffle 103, the end of the paper tube 300 that is printed is kept neat during transportation. The printed production batch number is in the same position on the surface of each paper tube 300, which facilitates subsequent production and management of the paper tube 300.
