Description

Technical Field

[0001] This utility model relates to an irradiation auxiliary device, and more particularly to an irradiation inlet and outlet plate device compatible with two inlets and two outlets. Background Technology

[0002] After irradiation treatment, the long-chain molecules of polymer materials can cross-link through chemical bonds to form a three-dimensional network structure, thereby significantly enhancing the intermolecular binding force and improving the material's mechanical strength, heat resistance, and chemical stability. X-rays and high-speed electron beams are commonly used irradiation methods. This technology has been widely applied in fields such as building wiring, automotive cables, heat-resistant electronic wires, and military applications. Currently, sheet irradiation transmission systems are widely used in the industry; however, existing systems still face several technical bottlenecks in practical operation, requiring urgent optimization and improvement.

[0003] Existing irradiation production equipment mostly adopts a "single-in, single-out" processing mode, meaning that only one type of sheet product can be processed at a time. Because the irradiation window width of the electron accelerator is fixed, to ensure uniform irradiation of the sheet and achieve the desired modification effect, the sheet width usually cannot exceed the effective width of the irradiation window. This results in the accelerator's irradiation area not being fully utilized when processing products with smaller widths, leading to significant waste of equipment capacity and energy.

[0004] Some manufacturers have attempted to place two different sizes of sheets side-by-side and feed them into the irradiation zone simultaneously using the same conveyor to improve efficiency. However, due to differences in the initial tension of the different sheets on the reel, the actual conveying speed varies due to uneven tension when using a shared conveyor. This speed difference directly results in inconsistent irradiation doses received by the sheets, severely affecting the uniformity and stability of product performance and making it difficult to guarantee the quality of the finished product. Utility Model Content

[0005] To address the aforementioned technical problems, this utility model discloses an irradiation sheet feeding and discharging device compatible with two-in-two-out irradiation methods, achieving true two-in-two-out, simultaneous feeding and discharging of different sheets, and the ability to individually control the conveying speed to precisely control the irradiation dose, as well as to achieve irradiation of a single wide sheet.

[0006] The technical solution of this utility model is as follows: A compatible dual-input, dual-output irradiation inlet / outlet sheet device includes: First film feeding mechanism, second film feeding mechanism, first film receiving mechanism, second film receiving mechanism, and beam transfer mechanism; The first film feeding mechanism and the second film feeding mechanism are staggered front to back, and the first film receiving mechanism and the second film receiving mechanism are staggered front to back; The beam-down transport mechanism includes several segmented active rollers arranged in parallel. Each segmented active roller includes a first active roller and a second active roller that can operate independently or in conjunction. The first and second active rollers are connected by a detachable connecting shaft. When the first and second active rollers operate independently, the several first active rollers and several second active rollers respectively form two beam-down passages, corresponding to the first sheet feeding mechanism / first sheet receiving mechanism and the second sheet feeding mechanism / second sheet receiving mechanism, respectively. The first and second active rollers are driven by independent power, so that the two types of sheets can run at different linear speeds, thereby simultaneously producing sheets with different irradiation doses. The sheet material conveyed from the first unloading mechanism reaches the first take-up mechanism via the first active roller of the segmented active roller of the bundle conveying mechanism. The sheet material transported from the second unloading mechanism reaches the second take-up mechanism via the second drive roller of the segmented drive roller of the bundle transfer mechanism.

[0007] In this technical solution, the under-beam transport mechanism includes several segmented active rollers arranged in parallel. Each segmented active roller includes a first active roller and a second active roller that can operate independently or in combination. That is, each segmented driven roller includes at least two independently controllable roller bodies. These roller bodies are connected by a transmission relationship and have at least two operating modes: in the first operating mode, each roller body operates independently; in the second operating mode, each roller body operates in combination. When the first and second active rollers are driven by independent power, i.e., controlled separately, two types of sheets can be irradiated simultaneously. In this case, the two types of rolled sheets are output through the first unloading mechanism and the second unloading mechanism, respectively. The sheet from the first unloading mechanism is then irradiated by the electron accelerator via the first active roller of the under-beam transport mechanism and then transferred to the first receiving mechanism; the sheet from the second unloading mechanism is irradiated by the electron accelerator via the second active roller of the under-beam transport mechanism and then transferred to the second receiving mechanism. When only one type of sheet needs to be irradiated, the first and second active rollers can be connected together and driven by one of them, for example, by the first unloading mechanism. After being irradiated by the electron accelerator beam through the segmented active rollers of the beam feeding mechanism, the sheet is transported to the first take-up mechanism for winding.

[0008] As a further improvement of this utility model, the rotation shafts of the first active roller and the second active roller are detachably connected by a connector.

[0009] As a further improvement of this utility model, the rotation shaft of the first active roller and the rotation shafts of the several second active rollers are coaxial. The rotation shafts of the first active roller and the several second active rollers can be connected or separated by a connector. When separated, they can be driven individually by their respective power drive mechanisms. When connected together, they can be driven by a single drive mechanism, at which point the rotation shafts of the first active roller and the several second active rollers form a single rotation shaft.

[0010] As a further improvement of this utility model, the beam-down transmission mechanism includes several segmented driven rollers. Each segmented driven roller includes a first driven roller and a second driven roller that can operate independently or in conjunction. The first driven roller and the second driven roller are connected by a detachable connecting shaft. In this technical solution, the segmented driven rollers serve as guide rollers. The usage of the segmented driven rollers corresponds to the usage of the segmented driving rollers.

[0011] As a further improvement of this invention, the length of the first active roller is greater than the length of the second active roller. This technical solution can meet the irradiation requirements of sheets of different widths.

[0012] As a further improvement of this utility model, the irradiation inlet and outlet compatible dual-inlet and dual-outlet wafer feeding and unloading device includes a roller assembly, which is located between the first wafer loading mechanism, the second wafer loading mechanism, and the under-beam transport mechanism. The roller assembly includes two segmented driven rollers for wafer feeding and wafer unloading, respectively. Each segmented driven roller includes a long driven roller and a short driven roller, with the length of the long driven roller being greater than the length of the short driven roller. The long roller group and the short roller group correspond to different under-beam paths; the long roller corresponds to an under-beam path composed of several first active rollers, and the short roller corresponds to an under-beam path composed of several second active rollers.

[0013] Using this technical solution, when irradiating one type of sheet, it can be guided and conveyed by several long rollers; when irradiating two types of sheets, long rollers and short rollers are used for guiding and conveying respectively.

[0014] As a further improvement of this utility model, the axial direction of the long roller and the short roller is perpendicular to the traveling direction of the sheet, and the surface of the long roller and the short roller is provided with an anti-slip layer.

[0015] As a further improvement of this utility model, one end of the long roller group and one end of the short roller group are located in the same plane.

[0016] As a further improvement of this utility model, the height of the discharge end of the first sheet feeding mechanism is higher than the discharge height of the discharge end of the second sheet feeding mechanism; the height of the feed end of the first sheet receiving mechanism is higher than the feed end of the second sheet receiving mechanism. Using this technical solution, when irradiating two specifications of sheets simultaneously, different discharge heights are used for output, and different feed heights are used for winding, preventing mutual interference during sheet transport.

[0017] As a further improvement of this utility model, the first receiving mechanism and the second receiving mechanism are located on the side closer to the beam-down transmission mechanism, and the first releasing mechanism and the second releasing mechanism are located on the side farther away from the beam-down transmission mechanism.

[0018] As a further improvement of this utility model, the first unwinding mechanism includes a first unwinding machine, a first unwinding tension mechanism, and a first unwinding and storage mechanism; the second unwinding mechanism includes a second unwinding machine, a second unwinding tension mechanism, and a second unwinding and storage mechanism; the first take-up mechanism includes a first take-up machine, a first take-up tension mechanism, and a first take-up and storage mechanism; and the second take-up mechanism includes a second take-up machine, a second take-up tension mechanism, and a second take-up and storage mechanism.

[0019] As a further improvement of this utility model, the first unwinding tension mechanism and the second unwinding tension mechanism are integrated on a single frame; the first winding tension mechanism and the second winding tension mechanism are integrated on a single tension frame, and a dual-traction tension machine is used for traction.

[0020] As a further improvement of this utility model, the first unwinding and storage mechanism and the second unwinding and storage mechanism are arranged adjacent to each other. The first unwinding and storage mechanism includes a plurality of first storage rollers, and the second unwinding and storage mechanism includes a plurality of second storage rollers. The length of the first storage rollers is greater than the length of the second storage rollers. An auxiliary roller is provided below the first storage rollers, the length of which is less than the length of the first storage rollers, and its position corresponds to that of the second storage rollers. The structure of the first winding and storage mechanism is the same as that of the first unwinding and storage mechanism, and the structure of the second winding and storage mechanism is the same as that of the second unwinding and storage mechanism. Using this technical solution, wide and narrow sheets enter two different storage mechanisms. When only one type of narrow sheet needs to be irradiated, the first unwinding and storage mechanism can be closed, and only the second unwinding and storage mechanism can be opened to transport the sheet. When two narrow sheets need to be processed simultaneously (two-in, two-out mode), the first and second unwinding and storage mechanisms simultaneously transport two sheets of different specifications from different transport paths. The first unwinding and storage mechanism and the second unwinding and storage mechanism are arranged adjacent to each other. Narrow sheets can reach the second storage roller through the auxiliary roller, which saves floor space and is convenient to use.

[0021] As a further improvement of this utility model, the beam-down transmission mechanism is slidably connected to the ground.

[0022] Compared with the prior art, the beneficial effects of this utility model are as follows: The technical solution of this utility model is compatible with irradiation transport of two-in-two-out and single sheet, and can realize the simultaneous entry and exit of different sheets. The transport speed of the two types of irradiation sheets can be controlled separately to accurately control the irradiation dose. It can also realize the irradiation of a single wide sheet.

Detailed Implementation

[0028] The preferred embodiments of the present invention will be further described in detail below with reference to the accompanying drawings.

[0029] like Figures 1-4As shown, an irradiation loading and unloading device compatible with two-input and two-output configurations includes: a first loading mechanism 1, a second loading mechanism 2, a first receiving mechanism 3, a second receiving mechanism 4, a beam under-transfer mechanism 5, and a roller assembly 6; the first loading mechanism 1 and the second loading mechanism 2 are staggered front to back, and the first receiving mechanism 3 and the second receiving mechanism 4 are also staggered front to back. The roller assembly 6 is located between the first receiving mechanism 3, the second receiving mechanism 4, and the beam under-transfer mechanism 5.

[0030] The beam-down transport mechanism 5 includes several segmented active rollers and several segmented driven rollers arranged in parallel. Each segmented active roller is formed by connecting a first active roller 51 and a second active roller 52, which can operate independently or in combination. When the first active roller 51 and the second active roller 52 operate independently, the several first active rollers 51 and the several second active rollers 52 respectively form two beam-down passages, corresponding to the first sheet feeding mechanism 1 / first sheet receiving mechanism 3 and the second sheet feeding mechanism 2 / second sheet receiving mechanism 4, respectively. The first active roller 51 and the second active roller 52 are driven by independent drive motors 53, so that the two types of sheets can run at different linear speeds, thereby simultaneously producing sheets with different irradiation doses. Each segmented driven roller is formed by connecting a first driven roller and a second driven roller, which can operate independently or in combination, and serves as a guide roller. The position of the first driven roller corresponds to the first active roller 51, and they have the same width; the position of the second driven roller corresponds to the second active roller 52, and they have the same width.

[0031] The sheet material is transferred from the first unloading mechanism 1 to the first take-up mechanism 3 via the first active roller 51 of the segmented active roller of the lower conveyor mechanism 5; the sheet material is transferred from the second unloading mechanism 2 to the second take-up mechanism 4 via the second active roller 52 of the segmented active roller of the lower conveyor mechanism 5.

[0032] The rotating shafts of several first active rollers 51 and several second active rollers 52 are coaxial. The rotating shafts of the first active rollers 51 and several second active rollers 52 can be connected or separated by a connector. When separated, they can be driven individually by their respective drive motors 53. When connected together, they can be driven by a single drive mechanism, in which case the rotating shafts of the first active rollers 51 and several second active rollers 52 form a single rotating shaft.

[0033] Furthermore, the length of the first active roller 51 is greater than the length of the second active roller 52.

[0034] The roller assembly 6 includes two segmented driven rollers for feeding and discharging the wafer, respectively. Each segmented driven roller includes a long driven roller 61 and a short driven roller 62, wherein the length of the long driven roller 61 is greater than the length of the short driven roller 62.

[0035] The height of the discharge end of the first wafer feeding mechanism 1 is higher than the discharge height of the discharge end of the second wafer feeding mechanism 2; the height of the feed end of the first wafer receiving mechanism 3 is higher than the feed end of the second wafer receiving mechanism 4. The first wafer receiving mechanism 3 and the second wafer receiving mechanism 4 are located on the side closer to the bundle transfer mechanism 5, and the first wafer feeding mechanism 1 and the second wafer feeding mechanism 2 are located on the side farther away from the bundle transfer mechanism 5.

[0036] The first unwinding mechanism 1 includes a first unwinding machine 11, a first unwinding tension mechanism 12, and a first unwinding and storage mechanism 13. The second unwinding mechanism 2 includes a second unwinding machine 21, a second unwinding tension mechanism 22, and a second unwinding and storage mechanism 23. The first unwinding tension mechanism 12 and the second unwinding tension mechanism 22 are integrated on a single frame. The first take-up mechanism 3 includes a first take-up machine 31, a first take-up tension mechanism 32, and a first take-up and storage mechanism 33. The second take-up mechanism 4 includes a second take-up machine 41, a second take-up tension mechanism 42, a second take-up and storage mechanism 43, and a dual traction tension machine 44. The first take-up tension mechanism 32 and the second take-up tension mechanism 42 are integrated on a single tension frame and are traction-based using the dual traction tension machine 44.

[0037] The first unwinding and storage mechanism 13 and the second unwinding and storage mechanism 23 are arranged adjacent to each other, with the second unwinding and storage mechanism 23 located in front of the first unwinding and storage mechanism 13. The first unwinding and storage mechanism 13 includes several first storage rollers 131, and the second unwinding and storage mechanism 23 includes several second storage rollers 231. The length of the first storage rollers 131 is greater than the length of the second storage rollers 231. An auxiliary roller 132 is provided below the first storage rollers 131, the length of the auxiliary roller 132 is less than the length of the first storage rollers 131, and its position corresponds to the second storage rollers 231. Wide and narrow sheets enter two different storage mechanisms. When only one type of narrow sheet needs to be irradiated, either the first unloading mechanism 1 or the second unloading mechanism 2 can be closed, and only the second unloading mechanism 2 or the first unloading mechanism 1 can be opened to transport the sheet. When only one type of wide sheet needs to be irradiated, the second unloading mechanism 2 can be closed, and only the first unloading mechanism 1 can be opened to transport the sheet. When two narrow sheets need to be processed simultaneously (two-in, two-out mode), the first sheet feeding mechanism 1 and the second sheet feeding mechanism 2 are activated at the same time, and the first unwinding and storage mechanism 13 and the second unwinding and storage mechanism 23 simultaneously convey two sheets of different specifications from different transmission paths. The narrow sheets reach the second storage roller 231 through the auxiliary roller 132, which saves floor space and is convenient to use.

[0038] Using this technical solution, when the first sheet and the second sheet are irradiated, the sum of the widths of the two sheets does not exceed the beam width of the electron accelerator. For the beam transport mechanism 5, the first active roller 51 and the second active roller 52 are driven by independent motors and controlled separately, enabling simultaneous irradiation of the first sheet and the second sheet, and controlling the transport speed and irradiation dose separately. In this case, the first sheet and the second sheet are output through the first sheet feeding mechanism 1 and the second sheet feeding mechanism 2, respectively. The first sheet of the first sheet feeding mechanism 1 is irradiated by the electron accelerator beam after passing through the first active roller 51 of the beam transport mechanism, and then transported to the first sheet receiving mechanism 3; the second sheet of the second sheet feeding mechanism 2 is irradiated by the electron accelerator beam after passing through the second active roller 52 of the beam transport mechanism, and then transported to the second sheet receiving mechanism 4. When only wide sheets need to be irradiated, the first active roller 51 and the second active roller 52 can be connected together. Driven by one of them, for example, the wide sheet is output through the first unloading mechanism 1, irradiated by the segmented active rollers of the beam-down conveying mechanism via an electron accelerator, and then transported to the first take-up mechanism 3 for winding. This embodiment achieves compatibility with single-size sheets and two-size sheets, and the irradiation dose can be controlled separately for each size, improving equipment utilization and production efficiency.
