[0001] The present invention relates to the technical field of inkjet printing devices, and particularly to an inkjet printing device for the dynamic transmission process of film materials. Background Art

[0002] In the production and processing of film materials, inkjet printing is an important process. Through inkjet printing, relevant information of the film materials can be marked, such as product model, production date, batch number, etc., which is convenient for product management, traceability, and sales. However, when inkjet printing is performed during the dynamic transmission of the film material, due to the soft texture of the film material itself, local relaxation, wrinkles and other phenomena are likely to occur, resulting in inaccurate inkjet printing positions, blurred and deformed inkjet printing patterns, seriously affecting the inkjet printing quality and marking effect.

When a group of film material abutting members gradually slide below the inkjet printing mechanism, the lifting member jacks up the film material abutting member to locally contact the film material and cause the film material to deform and be tensioned. Then, the inkjet printing mechanism sprays ink on the local part of the film material. After the inkjet printing is completed, the lifting member drives the film material abutting member to separate from the film material.

[0005] Preferably, the transmission member includes two drive shafts installed between the two side plates, and one drive shaft is connected to a group of film material conveying rollers.

When the film material abutting member slides below the inkjet coding mechanism, the jacking member jacks it up to locally tension the film material, avoiding phenomena such as slack and wrinkles of the film material during inkjet coding, thereby ensuring the accuracy of the inkjet coding position and the clarity and integrity of the inkjet coding pattern, significantly improving the inkjet coding quality. Moreover, the film material abutting member slides synchronously with the film material, ensuring that the film material abutting member always fits the movement rhythm of the film material.

[0018] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0019] As Figure 1-8 shown: Embodiment 1 of the present invention is: An inkjet coding device for the dynamic transmission process of film materials includes two side plates 1 arranged in parallel. Between the two side plates 1, two groups of film material conveying rollers 2 for conveying film materials are rotatably connected. A cross-shaped inkjet coding mechanism 3 is arranged between the tops of the two side plates 1, and the inkjet coding mechanism 3 is located between the two groups of film material conveying rollers 2. The two side plates 1 are provided with a film material abutting mechanism 4 that slides synchronously with the film material, and the film material abutting mechanism 4 is located below the film material; The film material abutting mechanism 4 includes a driving part 41 and a lifting part 42. The driving part 41 is connected to the film material conveying roller 2. A number of film material abutting parts 43 are equidistantly installed on the driving part 41. The driving part 41 drives the film material abutting parts 43 to slide synchronously with the film material. When a group of film material abutting parts 43 gradually slide below the inkjet coding mechanism 3, the lifting part 42 jacks up the film material abutting part 43 to make local contact with the film material and cause the film material to deform and be tensioned. Then, the inkjet coding mechanism 3 jets codes on the local part of the film material. After the coding is completed, the lifting part 42 drives the film material abutting part 43 to separate from the film material.

[0020] In this embodiment, the driving part 41 includes two driving shafts 411 installed between the two side plates 1. One driving shaft 411 is connected to a group of film material conveying rollers 2. Sprockets 412 are fixedly connected to the outer walls of the opposite ends of the two driving shafts 411. A driving chain 413 is connected between the two sprockets 412 on the same side. A number of mounting blocks 414 are equidistantly arranged on the top of the driving chain 413. A film material abutting part 43 is installed between the two opposite mounting blocks 414.

[0021] As can be seen from the above description: The transmission member adopts a structural design of a transmission shaft, a sprocket and a transmission chain, and a transmission shaft is connected to a group of film conveying rollers. This structure can stably and reliably transmit the power of the film conveying rollers to the film abutting member, ensuring that the film abutting member slides synchronously with the film. At the same time, the film abutting member is installed by setting an installation block on the top of the transmission chain, which is convenient for the installation and disassembly of the film abutting member. When the film abutting member is damaged or needs to be replaced with a film abutting member of a different specification, the operation is more convenient, improving the efficiency of equipment maintenance and upgrade. In addition, the combined transmission of the sprocket and the transmission chain has the advantages of accurate transmission ratio, high transmission efficiency and not easy to slip compared with other transmission methods, further ensuring the consistency of the movement of the film abutting member and the film, and ensuring that the film abutting member can accurately play the role of tensioning the film under the inkjet coding mechanism during the dynamic transmission of the film.

[0022] In this embodiment, the film abutting member 43 includes a fixed seat 431 connected to the installation block 414. A sliding rod 432 is slidably connected through the top of the fixed seat 431, and the bottom of the sliding rod 432 passes through the bottom of the fixed seat 431. An abutting block 433 is provided at the top of the sliding rod 432; The lifting member 42 includes a convex lifting block 421 directly below the inkjet coding mechanism 3, and both sides of the convex lifting block 421 are arc transition sections 422.

[0023] As can be seen from the above description: The connection between the fixed seat and the installation block provides a stable installation basis for the sliding rod and the abutting block; the through-sliding connection method between the sliding rod and the fixed seat enables the abutting block to move up and down flexibly under the action of the convex lifting block, realizing the tensioning and separating actions of the film. The arc transition sections on both sides of the convex lifting block can make the rollers at the bottom of the sliding rod move more smoothly during the contact and separation processes, reducing the friction and wear between the sliding rod and the convex lifting block, and extending the service life of the components. At the same time, this structural design can accurately control the tensioning force of the abutting block on the film by adjusting the height of the convex lifting block according to the thickness and material of the film, avoiding damage to the film due to excessive tension or inability to achieve the ideal tensioning effect due to too small tension, thereby improving the adaptability of the device to different films.

[0024] In this embodiment, a roller 434 is installed at the bottom of the sliding rod 432.

[0025] From the above description, it can be seen that when the film material abutting member moves along with the transmission chain and the sliding rod slides on the convex lifting block, the rolling friction of the roller is much smaller than the sliding friction, making the sliding of the sliding rod easier and smoother, reducing power loss, and ensuring that the film material abutting member can respond promptly and accurately to the lifting and lowering actions of the convex lifting block, ensuring the stable and reliable tensioning effect of the film material during inkjet coding. In addition, the presence of the roller can effectively avoid wear and scratches caused by long-term friction between the sliding rod and the convex lifting block, improve the wear resistance and service life of the components, and reduce the maintenance cost of the equipment.

[0026] In this embodiment, the inside of the fixed seat 431 is a hollow structure. A limiting rod 435 is installed between the side walls of the inner cavity of the fixed seat 431, and the limiting rod 435 penetrates through the sliding rod 432. The sliding rod 432 is provided with a strip-shaped groove that cooperates with the limiting rod 435. The opposite ends of the convex lifting block 421 are arc-shaped and adapted to the sprocket 412. The two ends of the convex lifting block 421 are flush with the sprockets 412 on both sides respectively. Limiting plates 423 are respectively arranged on the opposite side surfaces of the convex lifting block 421. A concave track that cooperates with the sliding rod 432 is formed between the two limiting plates 423 and the convex lifting block 421. A first screw rod 424 is threadedly connected through the convex lifting block 421, and one end of the first screw rod 424 passes through a side plate 1 and is equipped with a handwheel.

[0027] From the above description, it can be seen that the cooperation between the limiting rod in the fixed seat and the strip-shaped groove of the sliding rod accurately limits the sliding direction of the sliding rod, preventing the sliding rod from shifting or shaking during movement, ensuring that the abutting block can accurately contact the film material and tension the film material, and improving the stability and reliability of the operation of the film material abutting member. The arc-shaped design of the opposite ends of the convex lifting block adapted to the sprockets, as well as the limiting plates and concave track on both sides, not only further guides and standardizes the movement track of the sliding rod, but also forms a linkage mechanism with the adjustment function of the first screw rod. By rotating the first screw rod, the convex lifting block can be driven to slide left and right. Since the limiting plate is fixedly connected to the convex lifting block, the movement of the convex lifting block will drive the limiting plate to move synchronously. The sliding rod is always located in the concave track formed by the limiting plate and the convex lifting block during movement. Therefore, the movement of the limiting plate can drive the sliding rod to slide synchronously, thereby adjusting the horizontal position of the film material abutting member. This design enables the operator to flexibly adjust the position of the film material abutting member according to the actual width of the film material, ensuring that the abutting block can accurately act on the area of the film material that needs to be inkjet coded, and effectively solving the problem of inkjet coding adaptation for film materials of different widths.

[0028] In this embodiment, the inkjet coding mechanism 3 includes a gantry 31 straddling the side plate 1. At opposite ends of the top of the gantry 31, a second screw rod 32 is rotatably connected. One end of the second screw rod 32 passes through the end of the gantry 31 and is equipped with a second handwheel. A mounting seat 33 is threadedly connected to the outer wall of the second screw rod 32, and an inkjet coding member 34 is installed at the bottom of the mounting seat 33.

[0029] As can be seen from the above description: By rotating the second handwheel to drive the second screw rod to rotate, the mounting seat moves left and right along the second screw rod, thereby realizing the precise lateral adjustment of the position of the inkjet coding member. This structural design can conveniently and quickly adjust the inkjet coding member to the optimal inkjet coding position according to the different widths of the film material or the requirements of the inkjet coding position, ensuring that the inkjet coding can accurately act on the area where the film material needs to be marked, and the position of the abutting block can also be adjusted synchronously, so as to perform inkjet coding on different positions of the film material.

[0030] In this embodiment, a mounting groove is formed by inward depression at the top of the fixed seat 431. Two groups of UV lamp tubes 436 arranged in parallel are installed between the opposite side walls of the inner cavity of the mounting groove. The limiting rod 435 is located between the two groups of UV lamp tubes 436 and is arranged in parallel. Conductive columns 437 are respectively arranged at opposite ends of the fixed seat 431, and the conductive columns 437 are electrically connected to the UV lamp tubes 436. Conductive tracks 438 that cooperate with the conductive columns 437 are arranged on one side surface of the two side plates 1 that are close to each other. After the film material abutting member 43 is separated from the film material, the conductive columns 437 come into contact with the conductive tracks 438 and the UV lamp tubes 436 are powered on.

[0031] As can be seen from the above description: A mounting groove is provided at the top of the fixed seat and the UV lamp tubes are installed. At the same time, the power-on control of the UV lamp tubes is realized through the conductive columns and the conductive tracks. After the film material abutting member is separated from the film material, the conductive columns come into contact with the conductive tracks, and the UV lamp tubes are powered on, which can timely cure the ink after inkjet coding. This design can make full use of the time when the film material abutting member is in the non-working state to quickly cure the ink, improve the production efficiency, and reduce the waiting time for the ink to dry. The two groups of UV lamp tubes arranged in parallel can provide more uniform and sufficient ultraviolet irradiation to ensure that the ink can be cured comprehensively and quickly, effectively preventing the ink from being smeared or falling off, improving the qualified rate and aesthetics of the product. In addition, the contact power-on method of the conductive columns and the conductive tracks has a simple and reliable structure, is convenient for maintenance and repair, reduces the failure rate of the equipment, and this curing method can ensure that the UV lamp tubes have enough time to irradiate the film material without reducing the conveying speed of the film material, and will not reduce the inkjet coding efficiency.

[0032] In this embodiment, a limiting track 439 connected to both ends of the conductive track 438 is arranged on the side plate 1, and the limiting track 439 and the conductive track 438 are connected end to end to form a support track adapted to the transmission member 41.

[0033] As can be seen from the above description: in terms of conductive stability, the limiting track precisely constrains the movement trajectory of the conductive column, ensuring its continuous and stable contact with the conductive track, guaranteeing the timely power-on of the UV lamp tube, realizing the rapid curing of the ink, and improving the product qualification rate; in terms of equipment reliability, the adapted support track enables the smooth movement of the conductive column, reduces component wear, extends the service life of the conductive column and the conductive track, and reduces the risk of failure and maintenance costs; and regardless of how the film material conveying speed and the operating state of the abutting member change, the conductive column can precisely cooperate to meet the ink curing requirements under different working conditions, effectively improving the production efficiency and practicality of the equipment.

[0034] In this embodiment, the film material conveying roller 2 is drivingly connected to the transmission shaft 411 on the same side through a belt member.

[0035] As can be seen from the above description: the film material conveying roller is drivingly connected to the transmission shaft on the same side through a belt member. Belt drive has the advantages of simple structure, low cost, stable transmission, and low noise, and can effectively transmit the power of the film material conveying roller to the transmission shaft, thereby driving the film material abutting member to slide synchronously with the film material.

[0036] In this embodiment, the film material conveying roller 2 includes an upper roller 21 and a lower roller 22 arranged up and down. The upper roller 21 is made of elastic rubber, the lower roller 22 is made of metal, the lower roller 22 is drivingly connected to the transmission shaft 411 through a belt member, and a motor is installed at one end of a group of lower rollers 22.

[0037] As can be seen from the above description: the motor drives the lower roller. The belt member drive structure is simple and low-cost, and its characteristics of stable operation, low noise, and elastic buffering can not only ensure the stable and synchronous operation of the film material conveying roller and the film material abutting mechanism, but also protect the equipment by slipping when the equipment is overloaded; the rubber of the upper roller prevents the film material from slipping due to high friction, and cooperates with the metal lower roller to stably clamp, so that any film material can be reliably conveyed.

[0038] In this embodiment, a positioning ring is provided on the outer wall of the sliding rod 432, and a spring is sleeved thereon. The spring is located between the top of the positioning ring and the bottom of the fixed seat 431, and the positioning ring is located above the roller 434.

[0039] In this embodiment, a plurality of mounting blocks 414 for mounting the fixed seat 431 are provided on the drive chain 413, so that the mounting position of the fixed seat 431 can be adjusted according to different inkjet printing positions.

[0040] The specific working process of the above embodiment is as follows: A film unwinding mechanism and a film winding mechanism are respectively installed at both ends of the side plate 1, and the winding speed of the film winding mechanism is adapted to the motor speed of the film conveying roller 2. The film is then placed between the upper roller 21 and the lower roller 22 of the two sets of film conveying rollers 2 for conveyance. The motor installed at one end of one set of lower rollers 22 is started to provide a stable driving force for the lower roller 22. The lower roller 22 is connected to the transmission shaft 411 through a belt member, thereby driving the two transmission shafts 411 to rotate, so that the sprockets 412 installed at both ends of the transmission shaft 411 rotate accordingly, and the connected transmission chain 413 moves, driving the mounting blocks 414 equidistantly arranged on the top of the transmission chain 413 and the film abutment members 43 between the mounting blocks 414 to slide synchronously with the film material. When the film material needs to be coded, it is transferred to the position close to the bottom of the coding mechanism 3, and a group of film material abutments 43 also gradually slide to the bottom of the coding mechanism 3. At this time, the rollers 434 of the group of film material abutments 43 contact the arc transition section 422 of the convex lifting block 421 and gradually slide to the top of the convex lifting block 421, so that the abutment block 433 contacts the film material and lifts up the part of the film material, causing the part of the film material to be deformed and tensioned. In this process, the limit rod 435 in the fixed seat 431 cooperates with the strip groove of the sliding rod 432 to limit the sliding of the sliding rod 432. At the same time, the concave track formed between the limit plates 423 on the opposite sides of the convex lifting block 421 and the convex lifting block 421 also constrains the movement trajectory of the sliding rod 432, ensuring that the film material abutment 43 stably lifts the film material, and after lifting, the rollers 434 slide horizontally along the top of the convex lifting block 421.

[0041] After the film material is lifted, the film material abutment 43 and the film material move synchronously to the bottom of the coding mechanism 3, and the coding member 34 codes the lifted and tensioned part. Then, after the coding is completed, the roller 434 of the film material abutment 43 rolls to the other side of the top of the convex lifting block 421 and descends from the arc transition section 422, so that the abutment block 433 gradually separates from the film material, so that the part of the film material where the coding is completed returns to its original state and continues to be transported forward, completing the coding operation of the film material. Similarly, when the subsequent film material is coded, it abuts against the corresponding abutment block 433 and then codes are coded. This reciprocating process realizes the dynamic transmission and coding process of the film material. During the transmission of the film material abutting member 43, the conductive columns 437 at both ends of the fixed seat 431 slide within the limit track 439. And after the inkjet coding is completed, the conductive columns 437 gradually slide into the conductive track 438 (the conductive track 438 is arranged horizontally in a straight line). After the conductive columns 437 come into contact with the conductive track 438, the UV lamp tube 436 is powered on and lights up, thereby irradiating the inkjet coding position of the film material. And during the irradiation process, the UV lamp tube 436 always slides at the same speed and in the same direction as the film material, so that continuous irradiation can be carried out during the transmission of the film material, ensuring the irradiation time, ensuring the drying degree of the inkjet coding position while not reducing the transmission speed of the film material. Then the film material abutting member 43 continues to slide along with the transmission member 41 (slides downward and then slides back after reaching the end, and so on), and the dried film material is wound up by the winding mechanism.

[0042] When the film material needs to be inkjet coded at different positions (different horizontal positions), first rotate the second screw rod 32. The second screw rod 32 drives the mounting seat 33 and the inkjet coding member 34 to slide horizontally, so as to adjust the horizontal position of the inkjet coding member 34. Then rotate the first screw rod 424. The first screw rod 424 drives the convex lifting block 421 to slide horizontally. And because limiting plates 423 are arranged on both side surfaces of the convex lifting block 421, and the roller 434 of the film material abutting member 43 is located between the two limiting plates 423, so when the convex lifting block 421 slides, it can synchronously push the roller 434 and the sliding rod 432 to move horizontally along the limiting rod 435, so that the abutting block 433 slides below the inkjet coding member 34, thus realizing inkjet coding at different positions of the film material.
