Description

Technical Field

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

[0002] Digital inkjet printing technology has been widely used in the printing of various flexible sheet materials (such as packaging bags, brochures, textiles, etc.) due to its advantages of not requiring plate making and being able to flexibly handle small-batch customized production.

[0003] However, ensuring that soft, easily deformable materials maintain precise positioning and surface flatness within the printing area during high-speed, continuous production remains a core technological challenge for the industry. Existing equipment typically uses a pressing mechanism above the conveyor belt to apply downward pressure to the material to prevent it from tilting. However, this method only provides vertical constraints and is insufficient to correct horizontal positional shifts and angular deflections caused by initial feeding deviations, sliding on the conveyor belt, or inertia. The lack of proactive and effective correction methods along the material transport path, especially at critical stations before entering the printing area, results in compromised positional accuracy of the final printed pattern, increasing scrap rates and hindering further improvements in production efficiency. Utility Model Content

[0004] The purpose of this application is to provide a digital printing inkjet printing device that can correct the material before it enters the printing area, ensuring the accurate positioning of the material during the printing process, thereby improving printing quality and production efficiency.

A printing mechanism is located above the printing area and is used to print materials conveyed to the printing area by the conveyor belt. A pressing mechanism, located above the conveyor belt, is used to apply downward pressure to the material to stabilize its posture when the conveyor belt is conveying the material. The blocking and correction mechanism is located between the feeding end of the conveyor belt and the printing area. It is used to contact the pressing mechanism and drive the pressing mechanism to activate at least a part of the pressing mechanism to form a block on the material conveying path, thereby correcting the posture of the material on the conveyor belt and allowing the material to enter the printing area in a preset posture.

The second pressure strip assembly includes a second pressure strip fixing frame fixed on the machine body and spanning the conveyor belt, and two second fixing pressure strips symmetrically arranged on both sides of the second pressure strip fixing frame. One end of the second fixing pressure strip is fixed on the second pressure strip fixing frame, and the other end extends through the printing area along the conveying direction of the conveyor belt to the unloading end.

[0007] Optionally, the blocking and correction mechanism includes a blocking and correction fixing frame fixed between the first pressure bar fixing frame and the second pressure bar fixing frame, a blocking and correction cylinder vertically mounted on the blocking and correction fixing frame, and a blocking and correction plate fixed on the piston rod of the blocking and correction cylinder. The blocking and correction cylinder drives the blocking and correction plate to rise and fall vertically, so that the blocking and correction plate contacts the two first fixed pressure strips and presses the first fixed pressure strips toward the conveyor belt, thereby making the two first fixed pressure strips block the material and correct the position and posture of the material in the plane of the conveyor belt.

[0008] Optionally, the blocking and correcting plate includes a horizontal plate fixed on the piston rod of the blocking and correcting cylinder, and a vertical plate fixed on the bottom side of the horizontal plate and used to abut against two first fixed pressure strips. The horizontal plate is inclined upward on the side facing the feeding end.

[0009] Optionally, the second pressure strip assembly further includes two leveling pressure strips, which are arranged side by side between two second fixed pressure strips. One end of each leveling pressure strip is fixed to a second pressure strip fixing frame, and the other end extends along the conveying direction of the conveyor belt to directly below the printing mechanism.

[0010] Optionally, the printing mechanism includes a printing fixture fixed on the machine body, a crossbar mounted on the printing fixture and capable of sliding relative to the printing fixture in a direction perpendicular to the conveyor belt, and a printing head that can be raised and lowered on the crossbar.

The two ends of the flattening roller are rotatably connected to the two flattening fixing seats respectively.

[0013] Optionally, the digital printing inkjet equipment further includes an antistatic mechanism for removing static electricity from the surface of the material. The antistatic mechanism includes an antistatic mounting frame fixedly mounted on the side of the inkjet mounting frame facing the flattening mechanism and an antistatic bar mounted on the antistatic mounting frame.

[0014] Optionally, the digital printing equipment further includes a UV curing mechanism for UV curing the printed material. The UV curing mechanism includes a UV lamp mounting bracket fixed on the side of the printing fixture facing the unloading end and a UV curing lamp mounted on the UV lamp mounting bracket. The UV curing lamp is located above the unloading end, and the curing end of the UV curing lamp faces the conveyor belt.

[0015] After adopting the above technical solution, the beneficial effects of this utility model are as follows: This application provides a digital printing inkjet printing device, including a machine body, a conveyor belt, a printing mechanism, a pressing mechanism, and a blocking and correction mechanism. The pressing mechanism applies downward pressure to the material conveyed by the conveyor belt to stabilize the material's posture. Simultaneously, the blocking and correction mechanism contacts the pressing mechanism and drives at least a part of the pressing mechanism to actuate, forming a block on the material's conveying path. This corrects the posture of the material on the conveyor belt (i.e., the posture before the material enters the printing area), allowing the material to enter the printing area with a preset posture (correct position and angle). This effectively corrects the horizontal position deviation and angular deflection of the material caused by initial feeding deviation, sliding on the conveyor belt, or inertia, thereby ensuring accurate positioning of the material during the printing process and improving printing quality and production efficiency.

[0021] This embodiment provides a digital printing inkjet printing device, referring to... Figures 1-8 The system includes a machine body 100, a conveyor belt 10, a printing mechanism 20, a pressing mechanism 30, a blocking and correction mechanism 40, and a control mechanism. The surface of the machine body 100 is provided with a printing area 110. The conveyor belt 10 is rotatably mounted on the machine body 100, with its two ends being a loading end 11 and a unloading end 12, respectively. The printing area 110 is located between the loading end 11 and the unloading end 12. The conveyor belt 10 is used to transport materials from the loading end 11 to the printing area 110 and from the printing area 110 to the unloading end 12. The printing mechanism 20 is located above the printing area 110 and is used to print the materials transported by the conveyor belt 10 into the printing area 110.

[0022] The pressing mechanism 30 is located above the conveyor belt 10 and is used to apply downward pressure to the material to stabilize its posture when the conveyor belt 10 is conveying the material. The blocking and correction mechanism 40 is located between the feeding end 11 of the conveyor belt 10 and the printing area 110. It is used to contact the pressing mechanism 30 and drive the pressing mechanism 30 to make at least a part of the pressing mechanism 30 move to form a block on the material conveying path, thereby correcting the posture of the material on the conveyor belt 10 and making the material enter the printing area 110 in a preset posture.

[0023] The control mechanism is electrically connected to the conveyor belt 10, the printing mechanism 20, the pressing mechanism 30, and the blocking and correction mechanism 40, and is used to control the coordinated operation of the above mechanisms.

[0024] It should be noted that in this embodiment, the material is a flexible packaging bag such as a non-woven bag or a textile bag. In the actual production process, such flexible packaging bags are prone to positional shift and angular deflection during high-speed continuous conveying due to their soft texture and easy deformation.

[0025] During operation, the pressing mechanism 30 applies downward pressure to the material conveyed by the conveyor belt 10, keeping the material's posture stable. At the same time, the blocking and correction mechanism 40 contacts the pressing mechanism 30 and drives at least a part of the pressing mechanism 30 to move, forming a block on the material's conveying path. This corrects the posture of the material on the conveyor belt 10 (i.e., the posture before the material enters the printing area 110), allowing the material to enter the printing area 110 in a preset posture (correct position and angle). This effectively corrects the horizontal position deviation and angular deflection of the material caused by initial feeding deviation, sliding on the conveyor belt, or inertia, thereby ensuring accurate positioning of the material during the printing process and improving printing quality and production efficiency.

[0026] Furthermore, the pressing mechanism 30 includes a first pressing strip assembly 31 and a second pressing strip assembly 32, which are sequentially arranged between the feeding end 11 and the printing area 110 along the conveying direction of the conveyor belt 10. The first pressure bar assembly 31 includes a first pressure bar fixing frame 311 fixed on the machine body 100 and spanning the conveyor belt 10, and two first fixing pressure bars 312 symmetrically arranged on both sides of the first pressure bar fixing frame 311. One end of the first fixing pressure bar 312 is fixed on the first pressure bar fixing frame 311, and the other end extends along the conveying direction of the conveyor belt 10 to the area where the second pressure bar assembly 32 is located. The second pressure strip assembly 32 includes a second pressure strip fixing frame 321 fixed on the machine body 100 and spanning the conveyor belt 10, and two second fixing pressure strips 322 symmetrically arranged on both sides of the second pressure strip fixing frame 321. One end of the second fixing pressure strip 322 is fixed on the second pressure strip fixing frame 321, and the other end extends through the printing area 110 along the conveying direction of the conveyor belt 10 and extends to the unloading end 12.

[0027] During material conveying, the first fixing strip 312 applies initial pressure to the material to maintain its initial stable posture and reduce swaying and deviation in the early stages of conveying. Subsequently, the second fixing strip 322 applies further pressure to the material to ensure that it is completely stable before entering the printing area 110 and enters the printing area 110 accurately in a preset posture for the printing mechanism 20 to print. Since the end of the second fixing strip 322 away from the second fixing frame 321 extends from the printing area 110 to the unloading end 12, the second fixing strip 322 can continue to apply downward pressure to the material as it passes through the printing area 110 to the unloading end 12, maintaining the material's stable posture and preventing the material from shifting position or angle again due to inertia or other factors after printing, thus ensuring the durability and stability of the printing effect.

[0028] Furthermore, the blocking and correction mechanism 40 includes a blocking and correction fixing frame 41 fixed between the first pressure strip fixing frame 311 and the second pressure strip fixing frame 321, a blocking and correction cylinder 42 vertically mounted on the blocking and correction fixing frame 41, and a blocking and correction plate 43 fixed on the piston rod of the blocking and correction cylinder 42. The blocking and correction cylinder 42 drives the blocking and correction plate 43 to rise and fall vertically, so that the blocking and correction plate 43 contacts the two first fixed pressure strips 312 and presses the first fixed pressure strips 312 toward the conveyor belt 10, thereby making the two first fixed pressure strips 312 block the material and correct the posture of the material on the conveyor belt 10.

[0029] During operation, when the conveyor belt 10 transports the material to the first pressure bar assembly 31, the two first fixed pressure bars 312 work together to fix both ends of the material. At this time, the blocking and correction cylinder 42 drives the blocking and correction plate 43 to descend vertically. The descending blocking and correction plate 43 contacts the two first fixed pressure bars 312 and applies downward pressure, pressing the first fixed pressure bars 312 towards the conveyor belt 10. Since the first fixed pressure bars 312 already exert a certain pressure on the material, with the assistance of the blocking and correction plate 43, the two first fixed pressure bars 312 form a more effective obstruction of the material. This obstruction effect can promptly correct the posture of the material on the conveyor belt 10, returning the material to the preset conveying path and correct posture position, ensuring the accurate execution of subsequent printing work, and further improving the working stability and printing quality of the entire digital printing equipment.

[0030] Furthermore, the blocking and correcting plate 43 includes a horizontal plate 431 fixedly mounted on the piston rod of the blocking and correcting cylinder 42, and a vertical plate 432 fixedly mounted on the bottom side of the horizontal plate 431 and used to abut against the two first fixed pressure strips 312. The horizontal plate 431 is inclined upward on the side facing the feeding end 11.

[0031] During the process of the blocking and correction cylinder 42 driving the blocking and correction plate 43 to descend, the inclined surface of the horizontal plate 431 can play a certain guiding role for the material, thereby better correcting the posture of the material and ensuring the subsequent printing effect.

[0032] In addition, the blocking and correction mechanism 40 also includes a sensor 44 fixedly mounted on the blocking and correction frame. The sensor 44 is located on one side of the blocking and correction cylinder 42, with its sensing end facing the conveyor belt 10, and is used to sense the material. When the sensor 44 senses the material, it sends a signal to the control mechanism, which controls the blocking and correction cylinder 42 to move, causing the blocking and correction plate 43 to descend until it contacts the first fixing pressure bar 312 and presses the first fixing pressure bar 312 against the conveyor belt 10, thereby achieving the blocking and posture adjustment of the material.

[0033] Furthermore, the second pressure strip assembly 32 also includes two leveling pressure strips 323, which are arranged side by side between the two second fixed pressure strips 322. One end of the leveling pressure strip 323 is fixed to the second pressure strip fixing frame 321, and the other end extends along the conveying direction of the conveyor belt 10 to the bottom of the printing mechanism 20.

[0034] Understandably, the two leveling strips 323 further level the material surface before it is conveyed to the printing mechanism 20. When the material passes the second strip assembly 32, the two leveling strips 323 press against the material surface, eliminating any unevenness or wrinkles (especially in areas where patterns need to be printed), making the surface smoother. This allows the ink to adhere more evenly to the material surface during subsequent printing, preventing problems such as blurred or broken lines caused by uneven surfaces, effectively improving printing quality and ensuring the digital printing equipment can output high-quality printed products.

[0035] In addition, both the first pressure strip assembly 31 and the second pressure strip assembly 32 also include a pressure strip fixing adjustment block 33. The pressure strip fixing adjustment block 33 can slide relative to the first pressure strip fixing frame 311 and the second pressure strip fixing frame 321. The first fixed pressure strip 312 is fixed to the first pressure strip fixing frame 311 by the pressure strip fixing adjustment block 33. The second fixed pressure strip 322 and the leveling pressure strip 323 are both fixed to the second pressure strip fixing frame 321 by the pressure strip fixing adjustment block 33.

[0036] With the adjustment block 33 for the pressure strip, the operator can flexibly adjust the positions of the first fixed pressure strip 312, the second fixed pressure strip 322, and the leveling pressure strip 323 on the first pressure strip fixing frame 311 and the second pressure strip fixing frame 321 according to actual needs. This allows for better adaptation to the printing requirements of materials of different specifications and shapes, ensuring that the pressure strips can flatten and guide the materials under various conditions. This further enhances the adaptability of the digital printing equipment to different materials and the stability of the printing effect, thereby ensuring that the equipment can complete printing tasks efficiently and with high quality.

[0037] Furthermore, the printing mechanism 20 includes a printing fixture 21 fixedly mounted on the machine body 100, a crossbar 22 mounted on the printing fixture 21 and capable of sliding relative to the printing fixture 21 in a direction perpendicular to the conveyor belt 10, and a printing head 23 that can be raised and lowered on the crossbar 22. The second pressure strip assembly 32 and the printing area 110 are both located inside the printing fixture 21.

[0038] When the print head 23 needs to be adjusted to a position perpendicular to the conveyor belt 10, the crossbar 22 can slide relative to the print head holder 21, thereby moving the print head 23 to a suitable position to meet the printing requirements of materials of different widths. The print head 23 can be raised and lowered on the crossbar 22, allowing for flexible adjustment of its height according to the material height and specific printing requirements, ensuring print clarity and accuracy. The second pressure strip assembly 32 and the printing area 110 are both located inside the print head holder 21. This layout design makes the entire printing mechanism 20 compact, with more coordinated cooperation between components, which is beneficial for improving the working efficiency and printing quality of digital printing equipment.

[0039] Furthermore, the digital printing inkjet equipment also includes a surface tension treatment mechanism 50, which is used to remove the surface tension of the material. The surface tension treatment mechanism 50 includes a surface tension treatment fixture 51 fixed between the inkjet printing fixture 21 and the first pressure strip fixture 311, and a plasma gun head 52 disposed on the surface tension treatment fixture 51.

[0040] After the blocking and correction mechanism 40 and the first pressure strip assembly 31 work together to correct the posture of the material, the conveyor belt 10 continues to transport the material. When the material passes through the surface tension treatment fixture 51, the plasma gun head 52 on the surface tension treatment fixture 51 removes the surface tension of the material, thereby improving the surface characteristics of the material and making it more conducive to the subsequent printing process. This can effectively improve the adhesion of the printing ink to the surface of the material, making the printed pattern more firm and clear.

[0041] Furthermore, the digital printing inkjet equipment provided in this embodiment also includes a flattening mechanism 60, which is used to flatten the surface of the material. The flattening mechanism 60 includes two flattening fixing seats 61 symmetrically arranged on both sides of the conveyor belt 10, and a flattening roller 62 for flattening the surface of the material. The flattening fixing seats 61 are located between the surface tension treatment fixing frame 51 and the inkjet printing fixing frame 21. The two ends of the flattening roller 62 are respectively rotatably connected to the two flattening fixing seats 61.

[0042] After the surface tension of the material is removed by the surface tension treatment mechanism 50, the conveyor belt 10 continues to transport the material into the area of ​​the flattening mechanism 60. At this time, the flattening fixing seats 61 located on both sides of the conveyor belt 10 provide stable support, and the flattening rollers 62 rotate under the influence of the material or their own power, uniformly flattening the surface of the material. The flattened material surface is smoother, further improving the printing effect of subsequent inkjet printing processes and significantly improving the quality of the printed pattern.

[0043] Furthermore, the digital printing inkjet equipment provided in this embodiment also includes an antistatic mechanism 70, which is used to remove static electricity from the surface of the material. The antistatic mechanism 70 includes an antistatic mounting frame 71 fixedly mounted on the side of the inkjet mounting frame 21 facing the flattening mechanism 60 and an antistatic bar 72 mounted on the antistatic mounting frame 71.

[0044] After the material is flattened by the flattening mechanism 60, the conveyor belt 10 continues to transport the material into the area of ​​the static eliminator 70. At this time, the static eliminator mounting bracket 71, fixed to the side of the inkjet printing fixture 21 facing the flattening mechanism 60, provides a stable mounting position for the static eliminator 72. The static eliminator 72 then begins to work, effectively removing static electricity generated on the material surface due to friction and other reasons. The material after static electricity removal avoids the impact of static electricity attracting dust and other impurities on subsequent printing results, further ensuring the quality and clarity of the printed pattern.

[0045] Furthermore, the digital printing inkjet equipment provided in this embodiment also includes a UV curing mechanism 80, which is used to perform UV curing treatment on the printed material. It includes a UV lamp mounting frame 81 fixedly mounted on the side of the inkjet mounting frame 21 facing the unloading end 12 and a UV curing lamp 82 mounted on the UV lamp mounting frame 81. The UV curing lamp 82 is located above the unloading end 12, and the curing end of the UV curing lamp 82 faces the conveyor belt 10.

[0046] In this embodiment, the UV lamp mounting bracket 81 is slidably mounted on the inkjet printing fixture 21 and can slide along the conveying direction perpendicular to the conveyor belt 10, thereby adjusting the position of the UV curing lamp 82 relative to the conveyor belt 10. The UV curing lamp 82 can be raised and lowered on the UV lamp mounting bracket 81 to adjust the vertical distance between the UV curing lamp 82 and the conveyor belt 10, thereby meeting the curing requirements of different material thicknesses and inkjet printing requirements.

[0047] After the printing mechanism 20 completes the printing of the material, the conveyor belt 10 transports the printed material to the unloading end 12. Due to the continuous pressure provided by the second fixed pressure bar 322, the conveyor belt 10 can stably transport the material to the area below the printing mechanism 20 and the unloading end 12, keeping the material's posture stable and ensuring the consistency between the position of the printed pattern and the UV curing position. When the material passes through the UV fixing frame, the UV curing lamp 82 emits ultraviolet light of a specific wavelength to quickly cure the printed pattern on the material surface, allowing the pattern to dry and set rapidly. This effectively prevents problems such as blurring or peeling of the pattern during subsequent handling or storage, further improving printing quality and production efficiency.

[0048] In addition, the digital printing inkjet equipment provided in this embodiment also includes a limiting mechanism 90, which is used to limit the two sides of the material so that the conveyor belt 10 can stably transport the material.

[0049] There are two sets of limiting mechanisms 90, which are symmetrically arranged on both sides of the conveyor belt 10, and the two sets of limiting mechanisms 90 cooperate to limit the material on both sides.

[0050] Specifically, the limiting mechanism 90 includes a limiting seat 91 fixedly disposed on one side of the conveyor belt 10, a limiting rod 92 telescopically disposed on the limiting seat 91, a limiting plate 93 fixedly disposed on the limiting rod 92, and a fixing knob 94 for fixing the limiting rod 92. The limiting seat 91 has a through hole. One end of the limiting rod 92 is located outside the conveyor belt 10, and the other end passes through the through hole and extends above the conveyor belt 10. One end of the limiting plate 93 is located at the feeding end 11 of the conveyor belt 10, and the other end extends along the conveying direction of the conveyor belt 10 to the surface tension removal mechanism or the inkjet printing fixing frame 21. The fixing knob 94 is used to fix the limiting rod 92 to adjust the length of the limiting rod 92 extending into the conveyor belt 10 (i.e., the distance between the limiting plates 93 of the two sets of limiting mechanisms 90), so as to adapt to materials of different widths.

[0051] The above is only used to illustrate the technical solution of this utility model and not to limit it. Any other modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model, as long as they do not depart from the spirit and scope of the technical solution of this utility model, should be covered within the scope of the claims of this utility model.
