[0031] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0032] like Figure 1-8 As shown: Embodiment 1 of the present invention is:

[0033] A coding device for a dynamic film material transmission process includes two parallel side plates 1, two sets of film material conveying rollers 2 for conveying the film material are rotatably connected between the two side plates 1, a coding mechanism 3 is arranged across the top of the two side plates 1, and the coding mechanism 3 is located between the two sets of film material conveying rollers 2, and the two side plates 1 are equipped with a film material abutment mechanism 4 that slides synchronously with the film material, and the film material abutment mechanism 4 is located below the film material;

[0034] The film material abutment mechanism 4 includes a transmission member 41 and a lifting member 42, and the transmission member 41 is connected to the film material conveying roller 2. Several film material abutment members 43 are installed at equal distances on the transmission member 41. The transmission member 41 drives the film material abutment members 43 to slide synchronously with the film material, and when a group of film material abutment members 43 gradually slides under the coding mechanism 3, the lifting member 42 lifts the film material abutment members 43 to contact the local part of the film material and cause the film material to deform and tighten, and then the coding mechanism 3 codes the local part of the film material, and after the coding is completed, the lifting member 42 drives the film material abutment members 43 to separate from the film material.

[0035] In this embodiment, the transmission member 41 includes two transmission shafts 411 installed between the two side plates 1, and one transmission shaft 411 is connected to a group of film material conveying rollers 2. The outer walls of the two opposite ends of the two transmission shafts 411 are fixed with sprockets 412, and a transmission chain 413 is connected between the two sprockets 412 on the same side. A plurality of mounting blocks 414 are arranged at equal distances on the top of the transmission chain 413, and a film material abutment member 43 is installed between the two oppositely arranged mounting blocks 414.

[0036] From the above description, it can be seen that the transmission member adopts a structural design of a transmission shaft, sprocket and transmission chain, and a transmission shaft is connected to a set of film material conveying rollers. This structure can stably and reliably transmit the power of the film material conveying rollers to the film material abutment, ensuring that the film material abutment slides synchronously with the film material. At the same time, by providing a mounting block at the top of the transmission chain to install the film material abutment, it is convenient to install and remove the film material abutment. When the film material abutment is damaged or needs to be replaced with a film material abutment of different specifications, the operation is more convenient, which improves the efficiency of equipment maintenance and upgrade. In addition, the coordinated transmission of the sprocket and transmission chain has the advantages of accurate transmission ratio, high transmission efficiency, and low slip compared to other transmission methods. It further ensures the consistency of the movement of the film material abutment and the film material, ensuring that during the dynamic transmission of the film material, the film material abutment can accurately play the role of tensioning the film material under the inkjet mechanism.

[0037] In this embodiment, the membrane abutment member 43 includes a fixed seat 431 connected to the mounting block 414. A sliding rod 432 is slidably connected to 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 abutment block 433 is provided on the top of the sliding rod 432.

[0038] The lifting member 42 includes a convex lifting block 421 located directly below the inkjet printing mechanism 3 , and both sides of the convex lifting block 421 are arc transition sections 422 .

[0039] From the above description, it can be seen that the fixed seat is connected to the mounting block, providing a stable installation foundation for the sliding rod and the abutment block; the through-sliding connection between the sliding rod and the fixed seat enables the abutment block to flexibly move up and down under the action of the convex lifting block, thereby achieving the tensioning and separation of the membrane material, and the arc transition sections on both sides of the convex lifting block can make the rollers at the bottom of the sliding rod smoother during the contact and separation process, 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 abutment block on the membrane material by adjusting the height of the convex lifting block according to the thickness and material of the membrane material, avoiding damage to the membrane material due to excessive tensioning force, or failure to achieve the ideal tensioning effect due to too little tensioning force, thereby improving the adaptability of the device to different membrane materials.

[0040] In this embodiment, a roller 434 is installed at the bottom of the sliding rod 432 .

[0041] As can be seen from the above description, when the film material contact piece moves 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 rod slide more easily and smoothly, reducing power loss, ensuring that the film material contact piece can respond promptly and accurately to the lifting and lowering of the convex lifting block, and ensuring stable and reliable film tensioning during inkjet printing. Furthermore, the presence of the roller effectively prevents wear and scratches caused by prolonged friction between the sliding rod and the convex lifting block, improving the wear resistance and service life of the components and reducing equipment maintenance costs.

[0042] In this embodiment, the interior of the fixing seat 431 is a hollow structure. A limiting rod 435 is installed between the side walls of the inner cavity of the fixing seat 431. The limiting rod 435 passes through the sliding rod 432. The sliding rod 432 has a strip groove that cooperates with the limiting rod 435.

[0043] The opposite ends of the convex lifting block 421 are arc-shaped and matched with the sprocket 412, and the two ends of the convex lifting block 421 are respectively flush with the sprockets 412 on both sides. The convex lifting block 421 is provided with limit plates 423 on the opposite sides, and a concave track that cooperates with the sliding rod 432 is formed between the two limit plates 423 and the convex lifting block 421. The convex lifting block 421 is threadedly connected with a first screw rod 424, and one end of the first screw rod 424 passes through a side plate 1 and is installed with a hand wheel.

[0044] From the above description, it can be seen that the coordination between the limit rod in the fixed seat and the strip groove of the sliding rod precisely limits the sliding direction of the sliding rod, preventing the sliding rod from deflecting or shaking during movement, ensuring that the abutment block can accurately contact and tension the membrane material, and improving the stability and reliability of the membrane material abutment. The arc-shaped design of the convex lifting block, which is compatible with the sprocket at both ends, as well as the limit plates and concave track on both sides, not only further guides and regulates the movement trajectory of the sliding rod, but also forms a linkage mechanism with the adjustment function of the first screw. By rotating the first screw, the convex lifting block can be driven to slide left and right. Because the limit plate is fixedly connected to the convex lifting block, the sliding of the convex lifting block will simultaneously drive the movement of the limit plate. Since the sliding rod is always in the concave track formed by the limit plate and the convex lifting block during movement, the movement of the limit plate can simultaneously drive the sliding rod to slide, thereby adjusting the horizontal position of the membrane material abutment. This design allows the operator to flexibly adjust the position of the membrane abutment according to the actual width of the membrane, ensuring that the abutment block can accurately act on the area of ​​the membrane that needs to be coded, effectively solving the coding adaptation problem of membranes of different widths.

[0045] In this embodiment, the coding mechanism 3 includes a door frame 31 spanning the side panel 1, and a second screw 32 is rotatably connected to the opposite ends of the top of the door frame 31, and one end of the second screw 32 passes through the end of the door frame 31 and is installed with a second hand wheel. The outer wall of the second screw 32 is threadedly connected to a mounting seat 33, and a coding component 34 is installed at the bottom of the mounting seat 33.

[0046] As can be seen from the above description, turning the second handwheel drives the second screw, causing the mounting base to move left and right along the second screw, thereby achieving precise lateral adjustment of the coding element's position. This structural design allows the coding element to be quickly and easily adjusted to the optimal coding position based on the film's width or coding position requirements, ensuring that the coding is accurately applied to the desired marking area of ​​the film. The position of the abutment block can also be adjusted synchronously, allowing coding to be applied to different locations on the film.

[0047] In this embodiment, the top of the fixing seat 431 is recessed inward to form an installation groove, and two groups of UV lamps 436 arranged in parallel are installed between the opposite side walls of the inner cavity of the installation groove, and the limiting rod 435 is located between the two groups of UV lamps 436 and is arranged in parallel. Conductive columns 437 are respectively provided at the opposite ends of the fixing seat 431, and the conductive columns 437 are electrically connected to the UV lamps 436. A conductive track 438 that cooperates with the conductive column 437 is provided on the side where the two side panels 1 are close to each other. After the film material abutment 43 is separated from the film material, the conductive column 437 contacts the conductive track 438 and energizes the UV lamp 436.

[0048] As can be seen from the above description, a mounting slot is provided on the top of the mounting base for the UV lamp, which is then powered by a conductive post and conductive track. When the film contact member separates from the film, the conductive post contacts the conductive track, energizing the UV lamp and enabling immediate curing of the ink after inkjet printing. This design leverages the time when the film contact member is not in operation to rapidly cure the ink, improving production efficiency and reducing ink drying wait time. Two sets of UV lamps connected in parallel provide more uniform and sufficient UV exposure, ensuring comprehensive and rapid ink curing, effectively preventing ink smearing and shedding, and improving product quality and aesthetics. Furthermore, the contact-based power supply method between the conductive post and the conductive track offers a simple and reliable structure, facilitating maintenance and overhaul, and reducing equipment failure rates. Furthermore, this curing method ensures ample UV lamp exposure to the film without reducing film transport speed, thus minimizing inkjet printing efficiency.

[0049] In this embodiment, a limiting rail 439 connected to both ends of the conductive rail 438 is provided on the side panel 1 , and the limiting rail 439 and the conductive rail 438 are connected end to end to form a support rail adapted to the transmission member 41 .

[0050] From the above description, we can see that: in terms of conductive stability, the limit track accurately constrains the movement trajectory of the conductive column, ensuring its continuous and stable contact with the conductive track, ensuring that the UV lamp is energized in time, realizing rapid ink curing, and improving product qualification rate; in terms of equipment reliability, the adaptive support track enables the conductive column to move smoothly, 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 no matter how the film material transmission speed and the operating status of the abutment parts change, the conductive column can accurately cooperate to meet the ink curing requirements under different working conditions, effectively improving the production efficiency and practicality of the equipment.

[0051] In this embodiment, the film material conveying roller 2 is connected to the transmission shaft 411 on the same side via a belt transmission member.

[0052] As can be seen from the above description, the film conveyor roller is connected to the drive shaft on the same side via a belt drive. This belt drive offers advantages such as simple structure, low cost, smooth transmission, and low noise. It effectively transmits the power of the film conveyor roller to the drive shaft, thereby driving the film contact member to slide synchronously with the film.

[0053] In this embodiment, the film material conveying roller 2 includes an upper roller 21 and a lower roller 22 arranged upper and lower, and the upper roller 21 is made of elastic rubber, and the lower roller 22 is made of metal. The lower roller 22 is connected to the transmission shaft 411 through a belt transmission, and a motor is installed at one end of a group of lower rollers 22.

[0054] From the above description, we can see that the motor drives the lower roller, and the belt transmission structure is simple and low-cost. It is stable, low-noise, and has elastic buffering characteristics, which not only ensures the stable and synchronous operation of the film material conveying roller and the film material abutment mechanism, but also protects the equipment by slipping when the equipment is overloaded; the upper roller rubber prevents the film material from slipping with its high friction, and cooperates with the metal lower roller for stable clamping, so any kind of film material can be reliably conveyed.

[0055] In this embodiment, a positioning ring is provided on the outer wall of the sliding rod 432 and is sleeved with a spring. The spring is located between the top of the positioning ring and the bottom of the fixing seat 431 . The positioning ring is located above the roller 434 .

[0056] In this embodiment, a plurality of mounting blocks 414 for mounting the fixing seat 431 are provided on the transmission chain 413, so that the mounting position of the fixing seat 431 can be adjusted according to different coding positions.

[0057] The specific working process of the above embodiment is as follows:

[0058] 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.

[0059] 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.

[0060] 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.

[0061] During the transmission process of the film material abutment 43, the conductive posts 437 at both ends of the fixed seat 431 slide in the limiting track 439, and after the coding is completed, the conductive posts 437 gradually slide into the conductive track 438 (the conductive track 438 is arranged in a horizontal straight line). After the conductive posts 437 contact the conductive track 438, the UV lamp tube 436 is powered on and lights up, thereby irradiating the coding position of the film material, and during the irradiation process, the UV lamp tube 436 always slides at the same speed and direction as the film material, so that the film material can be irradiated continuously during the transmission process to ensure the irradiation time, and ensure the dryness of the coding position without reducing the film material transmission speed. Then the film material abutment 43 continues to slide with the transmission member 41 (slides to the end, slides downward and slides back, and so on), and the dried film material is wound up by the winding mechanism.

[0062] When the film material needs to be coded at different positions (different lateral positions), the second screw 32 is first rotated, and the second screw 32 drives the mounting seat 33 and the coding component 34 to slide horizontally, thereby adjusting the lateral position of the coding component 34, and then the first screw 424 is rotated, and the first screw 424 drives the convex lifting block 421 to slide horizontally. Since the limiting plates 423 are set on both sides of the convex lifting block 421, and the roller 434 of the film material abutment 43 is located between the two limiting plates 423, 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 abutment block 433 is slid to the bottom of the coding component 34, so that coding can be performed on different positions of the film material.

[0063] In the present invention, unless otherwise clearly stipulated and limited, the terms "install", "set", "connect", "fix", "screw" and the like should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integrated connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be the internal connection of two elements or the interaction relationship between two elements. Unless otherwise clearly defined, ordinary technicians in this field can understand the specific meanings of the above terms in the present invention according to the specific circumstances.

[0064] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes may be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
