Description

Technical Field

[0001] This utility model belongs to the technical field of cardboard box manufacturing equipment, and more specifically, it relates to an integrated machine for adhesive bonding and water-based ink printing. Background Technology

[0002] The adhesive-stamping and water-based ink printing integrated machine is an automated packaging equipment that integrates water-based ink printing, gluing (adhesion), and stapling (binding) functions. After the graphic printing is completed by the printing unit below, the gluing and stapling methods can be flexibly switched to achieve cardboard binding. It is widely used in the production and manufacturing of corrugated boxes. It mainly consists of a paper feeding unit, a printing unit, a die-cutting unit, a packing unit, a packaging unit, and a control system.

[0003] Existing application number: CN201822123251.5, a cardboard printing machine, including a cardboard printing machine, a control panel, a workbench support, a workbench, a support plate, an alarm, a fixed connecting plate, and a positioning connecting sleeve. The upper part of the cardboard printing machine has multiple control panels. The upper part of the cardboard printing machine is connected to the positioning connecting sleeve. The upper part of the positioning connecting sleeve is connected to the alarm. The outside of the alarm is connected to a fastening connecting sleeve. The lower part of the fastening connecting sleeve is connected to multiple fixed connecting plates. The fixed connecting plates are evenly distributed in the lower part of the fastening connecting sleeve. The alarm is connected inside the fixed connecting plate. The lower part of the fixed connecting plate is connected to the cardboard printing machine. The right side of the cardboard printing machine is connected to the workbench support. The upper part of the workbench support is connected to the workbench. The lower part of the workbench support is connected to the support plate. The right connecting plate is connected to a right connecting plate.

[0004] Based on the above, the paper feeding unit of the printing press relies on the operator to place the paperboard on the paper feeding rollers. The paper feeding rollers are driven by a motor to rotate, which in turn transports the paperboard to the printing unit. However, the manual placement process is highly dependent on the operator's experience, and it is difficult to ensure that the paperboard is accurately positioned in the center of the paper feeding unit. If the offset of the paperboard position exceeds the allowable range, it may cause significant deviations in the multi-color registration of the printing unit. At the same time, it may also cause uneven distribution of printing pressure, which will ultimately have a direct impact on the image accuracy and appearance quality of the finished product. Utility Model Content

[0005] To address the aforementioned technical problems, this utility model provides an integrated adhesive-stamping and water-based ink printing machine. This solves the problem that existing printing presses require operators to place the cardboard onto the feeding rollers, which are then driven by a motor to transport the cardboard to the printing unit. However, this manual placement process heavily relies on operator experience, making it difficult to ensure the cardboard is accurately positioned in the center of the feeding unit. If the cardboard's positional deviation exceeds the allowable range, it can lead to significant misregistration in multi-color printing within the printing unit, as well as uneven printing pressure distribution, ultimately directly impacting the image accuracy and appearance quality of the finished product.

[0006] The purpose and effect of this utility model, a combined adhesive and ink printing machine, are achieved by the following specific technical means:

[0007] A paper feeding unit body includes a paper feeding roller, a transmission box, connecting sliders, connecting plates, limiting plates, a centering component, and an adjusting component. Multiple paper feeding rollers are distributed and rotatably connected inside the paper feeding unit body. The transmission box is fixedly connected to the front of the paper feeding unit body. Two connecting sliders are distributed and slidably connected inside the front of the paper feeding unit body. Two connecting plates are fixedly connected at their bottoms to the front ends of the two connecting sliders. Two limiting plates are respectively located below the rear ends of the two connecting plates. The centering component is located inside the transmission box. Two sets of adjusting components are respectively located above the two limiting plates.

[0008] Furthermore, the centering assembly includes: a centering rack, a first drive shaft, and a centering gear; two centering racks are provided, and the outer ends of the two centering racks are respectively fixedly connected to the bottom of two connecting plates; the first drive shaft is rotatably connected to the paper feeding unit body and the inside of the transmission box; the centering gear is coaxially fixedly connected to the outside of the first drive shaft, and the centering gear meshes with the two centering racks respectively.

[0009] Furthermore, the centering assembly also includes a limiting ratchet and a limiting pawl; the limiting ratchet is coaxially fixedly connected to the front end of the first transmission shaft; the limiting pawl is rotatably connected inside the transmission box, and the limiting pawl engages with the limiting ratchet.

[0010] Furthermore, the centering assembly also includes: a pedal and a limiting spring; the pedal is fixedly connected to the bottom of the limiting pawl; the right end of the limiting spring is fixedly connected to the left side of the limiting pawl, and the left end of the limiting spring is fixedly connected to the inside of the transmission box.

[0011] Furthermore, the centering assembly also includes a centering spiral spring; the inner end of the centering spiral spring is coaxially fixedly connected to the rear end of the first drive shaft, and the outer end of the centering spiral spring is coaxially fixedly connected to the inside of the paper feeding unit body.

[0012] Furthermore, the adjustment assembly includes: a guide rod, an adjustment screw, and an adjustment knob; the guide rod is fixedly connected to the limiting plate and slidably connected to the connecting plate; the adjustment screw is rotatably connected to the limiting plate and threadedly connected to the connecting plate; the adjustment knob is coaxially fixedly connected to the adjustment screw.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] First, through the mechanical linkage structure of the centering component, when the connecting plate on one side is pushed, the connecting plate on the other side moves inward simultaneously, quickly pushing the cardboard to the center position of the main body of the paper feeding unit, ensuring accurate cardboard positioning, and facilitating the adjustment of the positions of the connecting plate and the limiting plate. This significantly improves the efficiency and accuracy of cardboard placement, and reduces printing misregistration and scrap rate.

[0015] Secondly, when the paper feeding rollers are worn or need to be adapted to different thicknesses of cardboard, turning the adjustment knob can drive the limit plate to move up and down, precisely adjusting the gap between the limit plate and the paper feeding rollers, so that the bottom height of the limit plate matches the height of the paper feeding rollers, ensuring that the cardboard is clamped evenly and stably under different working conditions, improving the equipment's adaptability to cardboard of various specifications, and reducing uneven printing pressure and finished product defects caused by clamping errors.

[0016] This invention achieves simultaneous alignment and locking of cardboard on both sides by mechanically linking the centering components and pushing a single-sided connecting plate, significantly improving cardboard alignment efficiency and accuracy. The adjustment components can precisely adjust the gap between the limiting plate and the paper feeding rollers to accommodate the clamping needs of paper feeding rollers with wear or cardboard of different thicknesses, avoiding printing defects caused by clamping errors. These improvements not only significantly improve production efficiency but also effectively reduce the defect rate, greatly reducing labor costs and material waste for enterprises, providing efficient and precise technical support for automated carton production.

Detailed Implementation

[0024] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0025] Example 1:

[0026] As attached Figure 1 To be continued Figure 5 As shown:

[0027] This utility model provides an integrated adhesive-backed ink printing machine, comprising a paper feeding unit body 1, paper feeding wheels 101, a transmission box 2, connecting sliders 3, connecting plates 301, limiting plates 601, and a centering component; multiple paper feeding wheels 101 are provided, and the multiple paper feeding wheels 101 are distributed and rotatably connected inside the paper feeding unit body 1; the transmission box 2 is fixedly connected to the front of the paper feeding unit body 1; two connecting sliders 3 are provided, and the two connecting sliders 3 are distributed and slidably connected inside the front of the paper feeding unit body 1; two connecting plates 301 are provided, and the bottom of the two connecting plates 301 are respectively fixedly connected to the front end of the two connecting sliders 3; two limiting plates 601 are provided, and the two limiting plates 601 are respectively located below the rear end of the two connecting plates 301; the centering component is located inside the transmission box 2.

[0028] The centering assembly includes: a centering rack 302, a first drive shaft 4, and a centering gear 401; two centering racks 302 are provided, and the outer ends of the two centering racks 302 are respectively fixedly connected to the underside of two connecting plates 301; the first drive shaft 4 is rotatably connected to the inside of the paper feeding unit body 1 and the transmission box 2; the centering gear 401 is coaxially fixedly connected to the outside of the first drive shaft 4, and the centering gear 401 meshes with the two centering racks 302 respectively.

[0029] The centering assembly also includes: a limiting ratchet 402 and a limiting pawl 5; the limiting ratchet 402 is coaxially fixedly connected to the front end of the first transmission shaft 4; the limiting pawl 5 is rotatably connected inside the transmission box 2, and the limiting pawl 5 meshes with the limiting ratchet 402.

[0030] The centering assembly also includes: a pedal 501 and a limiting spring 502; the pedal 501 is fixedly connected to the bottom of the limiting pawl 5; the right end of the limiting spring 502 is fixedly connected to the left side of the limiting pawl 5, and the left end of the limiting spring 502 is fixedly connected to the inside of the transmission box 2.

[0031] The centering assembly also includes a centering spiral spring 403; the inner end of the centering spiral spring 403 is coaxially fixedly connected to the rear end of the first drive shaft 4, and the outer end of the centering spiral spring 403 is coaxially fixedly connected to the inside of the paper feeding unit body 1.

[0032] The specific usage and function of this embodiment are as follows: In use, the flared openings formed at the front ends of the two connecting plates 301 facilitate the insertion of cardboard. After the cardboard is placed on the multiple paper feeding rollers 101, pushing any one of the connecting plates 301 inward causes the other connecting plate 301 to move inward synchronously through the gear and rack transmission mechanism formed by the two centering racks 302 meshing with the centering gear 401. This quickly pushes the cardboard to the center position of the paper feeding unit body 1. At the same time, under the action of the ratchet and pawl transmission mechanism formed by the limiting ratchet 402 and the limiting pawl 5, the connecting plate 301 can only move inward, thus ensuring that the two connecting plates 301 and the two limiting pawls 5 move inward. Plate 601 can remain in its current position and continue to limit the cardboard of the same model. When the width of the cardboard changes, the operator only needs to kick the pedal 501 to the left with their foot to disengage the limiting ratchet 402 and the limiting pawl 5. The centering spiral spring 403 is tightened during the inward movement of the connecting plate 301. After the limiting ratchet 402 and the limiting pawl 5 disengage, the centering spiral spring 403 rebounds, causing the two connecting plates 301 and the two limiting plates 601 to quickly return to their initial positions. Releasing the pedal 501, the limiting ratchet 402 and the limiting pawl 5 re-engage under the rebound of the limiting spring 502, which facilitates recalibration.

[0033] Example 2:

[0034] Based on Example 1, as shown in the appendix Figure 1 To be continued Figure 5 As shown, it also includes adjustment components, with two sets of adjustment components, which are respectively set above the two limit plates 601.

[0035] The adjustment assembly includes: a guide rod 6, an adjusting screw 7, and an adjusting knob 701; the guide rod 6 is fixedly connected to the limiting plate 601 and is slidably connected to the connecting plate 301; the adjusting screw 7 is rotatably connected to the limiting plate 601 and is threadedly connected to the connecting plate 301; the adjusting knob 701 is coaxially fixedly connected to the adjusting screw 7.

[0036] The specific usage and function of this embodiment: The paper feeding roller 101 may wear during use, or the height of the paper feeding unit body 1 exposed on the table surface may be adjusted according to actual usage needs. When the height of the paper feeding roller 101 changes, the adjustment knob 701 is rotated. Under the guidance of the guide rod 6, the threaded transmission mechanism formed by the adjusting screw 7 and the connecting plate 301 drives the limiting plate 601 to move up and down, so that the bottom height of the limiting plate 601 can match the height of the paper feeding roller 101, making the clamping of the paperboard more precise and preventing the paperboard from passing through the gap between the limiting plate 601 and the paper feeding roller 101 during the inward movement of the limiting plate 601.
