Description

Technical Field

[0001] This invention relates to the field of irradiated environmentally friendly flooring production technology, specifically to a large-scale irradiated environmentally friendly flooring production line. Background Technology

[0002] An electron accelerator is a device that can generate high-energy electron beams with strong current. Its working principle is as follows: First, it converts the 50Hz low-voltage power energy into 400Hz medium-frequency power energy using an oscillator. Then, it supplies power to a voltage doubler rectifier circuit composed of diodes and space capacitors in parallel through high-frequency coupling. After parallel connection, an extremely high current voltage is obtained. By accelerating electrons, the desired high-energy electron beams with strong current can be obtained.

[0003] Irradiation processing uses high-energy electron beams to irradiate materials, breaking the covalent bonds in the polymer structure and forming an interconnected network structure between linear polymers, thereby improving and enhancing various properties of the material, such as heat resistance, pressure resistance, aging resistance, and insulation properties.

[0004] During the irradiation process, electron beams irradiate the product, and at the same time, electron beams irradiate the ground or other material surfaces. For example, a large-scale irradiation environmental protection flooring production line produces environmental protection flooring with stronger heat resistance, pressure resistance, aging resistance and insulation properties through irradiation technology.

[0005] The existing publication number CN111647236A discloses an irradiated flooring fabric and its preparation method. This irradiated flooring is produced using irradiation technology. In the production process, cold pressing technology is used to cool the thick sheet during molding. By controlling the heat dissipation temperature and based on the material characteristics of the sample, the linear cooling of the sample is maintained to ensure that the sample is formed in the best state, completely eliminating internal stress, resulting in better overall performance of the substrate and ensuring the quality of the product in production and use. However, the flooring fabric is directly fed into the irradiation equipment. In this way, the flooring fabric cannot be kept in a taut state after entering the irradiation equipment, or it is too taut, which leads to damage to the flooring fabric and is not conducive to the production of irradiated environmentally friendly flooring. Summary of the Invention

[0006] To overcome the aforementioned technical problems, the present invention aims to provide a large-scale irradiated environmentally friendly floor production line. Sheets can be conveyed from a support frame to a tension storage rack. The bottom and top tension wheel sets in the tension storage rack automatically adjust the distance between their internal structures, ensuring the sheets are kept taut upon entering the rack. This prevents wrinkling when the sheets enter the irradiation mechanism, guaranteeing the irradiation effect. The sheet feeding mechanism at the front of the tension storage rack can automatically adjust its height, controlling the height at which the sheets enter the rack. This allows the tension storage rack to be used with sheet feeding machines and traction machines of different specifications, improving its applicability.

[0007] The objective of this invention can be achieved through the following technical solutions:

[0008] A large-scale irradiated environmentally friendly flooring production line includes a production platform. The top surface of the production platform is sequentially equipped with a sheet feeding machine, a support frame, a tension sheet storage rack, a web guiding machine, an irradiation mechanism, a traction machine, and a winding machine. The environmentally friendly flooring sheets are fed out by the sheet feeding machine and collected by the winding machine. The traction machine transports the sheets through the tension sheet storage rack and the web guiding machine to the winding machine. The tension sheet storage rack is equipped with a sheet feeding mechanism, a bottom tension wheel assembly, and a top tension wheel assembly. The sheet feeding mechanism is used to adjust the height of the sheet entering the tension sheet storage rack. The bottom tension wheel assembly and the top tension wheel assembly work together to automatically adjust the distance between the internal structures to keep the sheet taut.

[0009] As a further aspect of the present invention: the irradiation mechanism includes a main body, a shielding accelerator is provided at the top of the inner cavity of the main body, and a blocking target and a particle accelerator are provided at the bottom of the inner cavity of the main body.

[0010] As a further aspect of the present invention: the feeding mechanism includes a lifting seat, a threaded rod inserted into one side of the lifting seat, the threaded rod being vertically mounted inside the tension storage rack via a bearing, an adjusting shaft engaging at the top of the threaded rod, a gear fixedly connected to one end of the adjusting shaft near the threaded rod, and a helical gear fixedly connected to the top of the threaded rod. The gear at one end of the adjusting shaft meshes with the helical gear at the top of the threaded rod, so that when the adjusting shaft is rotated, the adjusting shaft can drive the threaded rod to rotate. An opening inside the lifting seat near the threaded rod is provided that engages with the threaded rod. The tension storage rack has a threaded groove, and the end face of the tension storage rack near the lifting seat has a lifting groove that matches the lifting seat. When the threaded rod rotates, it can drive the lifting seat to rise and fall freely. Two sets of vertically arranged feeding wheels are installed on one side of the lifting seat. The height of the two sets of feeding wheels can also be adjusted. The sheet passes through the space between the two sets of feeding wheels into the tension storage rack. In this way, the height of the sheet entering the tension storage rack can be controlled by the two sets of feeding wheels, so that the tension storage rack can be used with different specifications of unloading machines and traction machines, thus improving its applicability.

[0011] As a further embodiment of the present invention: the side of the adjusting shaft is provided with two sets of ratchet teeth, the two sets of ratchet teeth are facing opposite directions, an electromagnet is provided at the top of the adjusting shaft near the ratchet teeth, and two sets of limit clips are movably connected to the bottom of the electromagnet, the two sets of limit clips respectively engage with the two sets of ratchet teeth, and a rotating disk is fixedly connected to one end of the adjusting shaft.

[0012] When the rotating disc is turned, it drives the adjusting shaft to rotate. At this time, the electromagnet needs to be turned on. The electromagnet is divided into two groups, which control two sets of limit clips respectively. The limit clips are made of magnetic material. When the electromagnet is turned on, it will generate a magnetic attraction force to hold the limit clips and make them disengage from the ratchet. This allows the adjusting shaft to rotate freely. When it is necessary to fix the adjusting shaft, the electromagnet is turned off. The limit clips will then be locked on the side of the ratchet under the action of the spring force. The ratchet can fix the adjusting shaft, thereby also fixing the feed wheel.

[0013] As a further aspect of the present invention: the bottom tension wheel assembly includes a movable frame, the movable frame is fixed to the bottom of the inner cavity of the tension storage rack, a rotating rod is installed in the middle of the interior of the movable frame, and four sets of rotating wheels are installed on the front of the movable frame.

[0014] As a further aspect of the present invention: two long ropes are wound around the side of the rotating rod, and an adjusting gear is fixedly connected to the end of each of the two long ropes away from the rotating rod. A first adjusting rod and a second adjusting rod are respectively engaged on both sides of the adjusting gear. A rotating shaft is fixedly connected to one end of each of the first adjusting rod and the second adjusting rod. The rotating wheel is nested on the outside of the rotating shaft.

[0015] As a further aspect of the present invention: the top of the adjusting gear is engaged with an adjusting rail, and the adjusting rail is fixed inside the movable frame.

[0016] As a further aspect of the present invention: the top tension wheel assembly includes a first wheel, a second wheel, and a third wheel, and a telescopic rod is provided between the first wheel and the second wheel, as well as between the second wheel and the third wheel, and a telescopic spring is nested on the side of the telescopic rod.

[0017] As a further embodiment of the present invention: a limiting seat is fixedly connected to the top of the first wheel, a limiting sleeve is fixedly connected to the top of the second wheel, and an anti-detachment sleeve is fixedly connected to the top of the third wheel. A rotating screw is inserted inside the limiting seat, and the rotating screw passes through the limiting sleeve and is threadedly connected to the anti-detachment sleeve.

[0018] The beneficial effects of this invention are:

[0019] 1. In this invention, the sheet material can be conveyed to the tension storage rack by the support frame. The bottom tension wheel group and the top tension wheel group in the tension storage rack will cooperate to automatically adjust the distance between the internal structures, so that the sheet material entering the tension storage rack is automatically kept taut. In this way, no wrinkles will occur when entering the irradiation mechanism, ensuring the irradiation effect of the irradiation mechanism. The feeding mechanism at the front end of the tension storage rack can automatically adjust the height, so as to control the height of the sheet material entering the tension storage rack, so that the tension storage rack can be used with different specifications of feeding machines and traction machines, improving its applicability.

[0020] 2. In this invention, when the rotating disk is rotated, it will drive the adjusting shaft to rotate. At this time, the electromagnet needs to be turned on. The electromagnet is divided into two groups, which control two sets of limit cards respectively. The limit cards are made of magnetic material. After the electromagnet is turned on, it will generate magnetic attraction to hold the limit cards and make them disengage from the ratchet. In this way, the adjusting shaft can rotate freely. When it is necessary to fix the adjusting shaft, the electromagnet is turned off. In this way, the limit cards will be locked on the side of the ratchet under the action of the spring force. The ratchet can fix the adjusting shaft, thereby also fixing the feed wheel.

[0021] 3. In this invention, the adjusting track is fixed inside the moving frame, so it will rotate during the movement of the adjusting gear, and will drive the first adjusting rod and the second adjusting rod to move. A spring is set between the two sets of second adjusting rods, so that the distance between the four sets of rotating wheels can be controlled and the distance between the four sets of rotating wheels can be freely adjusted. In this way, after the sheet passes through the four sets of rotating wheels, the four sets of rotating wheels can control the tension between the sheets, and due to the elasticity of the spring, the sheets are prevented from being too tight, thus improving safety.

[0022] 4. In this invention, the telescopic rod and telescopic spring between the first, second, and third wheels can provide a buffering effect and can slightly adjust the distance between the sheets to keep the sheets taut. When the elasticity of the telescopic spring is too small, the screw can be rotated. Rotating the screw can work with the anti-disengagement sleeve to control the maximum distance between the first, second, and third wheels, that is, to control the elasticity of the telescopic spring. When the distance increases, the elasticity decreases; when the distance decreases, the elasticity increases, making the top tension wheel group more effective in controlling the tautness of the sheets.

[0034] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0035] like Figures 1-9 As shown, a large-scale irradiated environmentally friendly flooring production line includes a production platform 1. The top surface of the production platform 1 is sequentially equipped with a sheet feeding machine 2, a support frame 3, a tension sheet storage rack 4, a web guiding machine 5, an irradiation mechanism 6, a traction machine 7, and a winding machine 8. The sheets of environmentally friendly flooring are discharged by the sheet feeding machine 2 and collected by the winding machine 8. The traction machine 7 transports the sheets through the tension sheet storage rack 4 and the web guiding machine 5 to the winding machine 8. The tension sheet storage rack 4 includes a storage rack body 41, on which a sheet feeding mechanism 42, a bottom tension wheel set 43, and a top tension wheel set 45 are provided. On the other side of the storage rack body 41, a sheet discharge wheel 46 is provided. The sheet feeding mechanism 42 is used to adjust the height of the sheet entering the tension sheet storage rack 4. The bottom tension wheel set 43 and the top tension wheel set 45 cooperate with each other to automatically adjust the distance between the internal structures to keep the sheet taut.

[0036] like Figure 1 and Figure 8 As shown, the irradiation mechanism 6 includes a main body 61, the top of which is a beam target chamber. The main body 61 is a two-layer reinforced concrete structure. A shielding accelerator 62 is provided at the top of the inner cavity of the main body 61, and a blocking target 64 and a particle accelerator 65 are provided at the bottom of the inner cavity of the main body 61. Passive rollers 63 are provided on both sides of the blocking target 64. The passive rollers 63 can transport the sheet between the blocking target 64 and the particle accelerator 65. An electron accelerator is also provided inside the main body 61. The electron accelerator can accelerate electrons to obtain the required high-current high-energy electron beams. When the sheet passes through the particle accelerator 65, the high-current high-energy electron beams can irradiate the sheet. The radiation of the high-current high-energy electron beams can open the covalent bonds in the polymer structure of the sheet, so that the linear polymers form an interconnected network structure, thereby improving the heat resistance, pressure resistance, aging resistance and insulation properties of the material.

[0037] During operation, the film feeder 2 provides the film, which is then conveyed by the support frame 3 to the tension storage rack 4. The bottom tension wheel assembly 43 and the top tension wheel assembly 45 in the tension storage rack 4 work together to automatically adjust the distance between the internal structures, ensuring that the film entering the tension storage rack 4 is automatically kept taut. This prevents wrinkling when the film enters the irradiation mechanism 6, thus ensuring the irradiation effect of the irradiation mechanism 6. The film feeding mechanism 42 at the front end of the tension storage rack 4 can automatically adjust its height, thereby controlling the height at which the film enters the tension storage rack 4. This allows the tension storage rack 4 to be used with film feeders 2 and traction machines 7 of different specifications, improving its applicability.

[0038] like Figure 3As shown, the feeding mechanism 42 includes a lifting seat 421. A threaded rod 422 is inserted into one side of the lifting seat 421. The threaded rod 422 is vertically installed inside the tension storage rack 4 via bearings. An adjusting shaft 424 is engaged at the top of the threaded rod 422. A gear is fixedly connected to one end of the adjusting shaft 424 near the threaded rod 422, while a helical gear is fixedly connected to the top of the threaded rod 422. The gear at one end of the adjusting shaft 424 meshes with the helical gear at the top of the threaded rod 422. Thus, when the adjusting shaft 424 is rotated, it can drive the threaded rod 422 to rotate. An opening is provided inside the lifting seat 421 near the threaded rod 422 to interact with the threaded rod 422. The tension storage rack 4 has a matching threaded groove, and the end face of the tension storage rack 4 is provided with a lifting groove that matches the lifting seat 421. When the threaded rod 422 rotates, it can drive the lifting seat 421 to rise and fall freely. Two sets of vertically arranged feeding wheels 423 are installed on one side of the outer side of the lifting seat 421. The height of the two sets of feeding wheels 423 can also be adjusted. The sheet passes between the two sets of feeding wheels 423 to enter the tension storage rack 4. In this way, the height of the sheet entering the tension storage rack 4 can be controlled by the two sets of feeding wheels 423, so that the tension storage rack 4 can be used with different specifications of unloading machine 2 and traction machine 7, thus improving its applicability.

[0039] like Figure 4 As shown, the side of the adjusting shaft 424 is provided with two sets of ratchet teeth 426, which face opposite directions. An electromagnet 427 is provided on the top of the adjusting shaft 424 near the ratchet teeth 426. Two sets of limit clips 428 are movably connected to the bottom of the electromagnet 427. The two sets of limit clips 428 respectively engage with the two sets of ratchet teeth 426. A rotating disk 425 is fixedly connected to one end of the adjusting shaft 424.

[0040] When the rotating disk 425 is rotated, it will drive the adjusting shaft 424 to rotate. At this time, the electromagnet 427 needs to be turned on. The electromagnet 427 is divided into two groups, which control two sets of limit cards 428 respectively. The limit cards 428 are made of magnetic material. When the electromagnet 427 is turned on, it will generate a magnetic attraction force to attract the limit cards 428, causing them to disengage from the ratchet 426. This allows the adjusting shaft 424 to rotate freely. When it is necessary to fix the adjusting shaft 424, the electromagnet 427 is turned off. The limit cards 428 will then be locked on the side of the ratchet 426 under the action of the spring force. The ratchet 426 can fix the adjusting shaft 424, thereby also fixing the feed wheel 423.

[0041] like Figure 5 As shown, the bottom tension wheel assembly 43 includes a movable frame 431, which is fixed to the bottom of the inner cavity of the tension storage rack 4. A rotating rod 433 is installed in the middle of the inner part of the movable frame 431, and four sets of rotating wheels 432 are installed on the front of the movable frame 431.

[0042] like Figure 6 As shown, two long ropes are wound around the side of the rotating rod 433. The ends of the two long ropes away from the rotating rod 433 are fixedly connected to the adjusting gear 434. The two sides of the adjusting gear 434 are respectively engaged with the first adjusting rod 435 and the second adjusting rod 436. The ends of the first adjusting rod 435 and the second adjusting rod 436 are fixedly connected to the rotating shaft 437. The rotating wheel 432 is nested on the outside of the rotating shaft 437. The top of the adjusting gear 434 is engaged with the adjusting track 44. The adjusting track 44 is fixed inside the moving frame 431.

[0043] During operation, rotating the rotating rod 433 pulls the adjusting gear 434 via two long ropes. Since the top of the adjusting gear 434 is engaged with the adjusting rail 44, which is fixed inside the moving frame 431, the adjusting gear 434 rotates during its movement, driving the first adjusting rod 435 and the second adjusting rod 436 to move. A spring is installed between the two sets of second adjusting rods 436, which controls the distance between the four sets of rotating wheels 432 and allows the distance between the four sets of rotating wheels 432 to be freely adjusted. After the sheet passes through the four sets of rotating wheels 432, the four sets of rotating wheels 432 can control the tension between the sheets, and due to the spring force, the sheets are prevented from being too tight, thus improving safety.

[0044] like Figure 7 As shown, the top tension wheel assembly 45 includes a first wheel 451, a second wheel 452, and a third wheel 453. Telescopic rods 454 are provided between the first wheel 451 and the second wheel 452, and between the second wheel 452 and the third wheel 453. Telescopic springs 455 are nested on the side of the telescopic rods 454. A limiting seat 456 is fixedly connected to the top of the first wheel 451. A limiting sleeve 458 is fixedly connected to the top of the second wheel 452. An anti-detachment sleeve 459 is fixedly connected to the top of the third wheel 453. A rotating screw 457 is inserted inside the limiting seat 456. The rotating screw 457 passes through the limiting sleeve 458 and is threadedly connected to the anti-detachment sleeve 459.

[0045] When the sheet passes through the first wheel 451, the second wheel 452, and the third wheel 453, the telescopic rod 454 and the telescopic spring 455 between the first wheel 451, the second wheel 452, and the third wheel 453 can provide a buffering effect and can slightly adjust the distance between the sheets to keep the sheets taut. When the elasticity of the telescopic spring 455 is too small, the rotating screw 457 can be rotated. Rotating the screw 457 can work with the anti-slip sleeve 459 to control the maximum distance between the first wheel 451, the second wheel 452, and the third wheel 453, which means controlling the elasticity of the telescopic spring 455. When the distance increases, the elasticity decreases; when the distance decreases, the elasticity increases, making the top tension wheel assembly 45 more effective in controlling the tautness of the sheet.

[0046] Working principle of the invention:

[0047] The sheet feeder 2 provides sheet material, which is conveyed by the support frame 3 to the tension storage rack 4. The bottom tension wheel assembly 43 and the top tension wheel assembly 45 in the tension storage rack 4 work together to automatically adjust the distance between their internal structures, ensuring the sheet material is kept taut upon entering the tension storage rack 4. This prevents wrinkling when the sheet material enters the irradiation mechanism 6. Once the sheet material enters the irradiation mechanism 6, the main body 61 of the mechanism is equipped with an electron accelerator. The electron accelerator accelerates electrons to obtain the required high-current, high-energy electron beams. When the sheet material passes through the particle... When the accelerator is 65, it can irradiate the sheet with high-current high-energy electron beams. The radiation of the high-current high-energy electron beams can break the covalent bonds in the polymer structure of the sheet, so that the linear polymers form an interconnected network structure, thereby improving the heat resistance, pressure resistance, aging resistance and insulation properties of the material. The sheet coming out of the irradiation device 6 can be pulled out by the traction machine 7. The traction machine 7 transports the sheet through the tension storage rack 4 and the web guiding machine 5 to the winding machine 8. The traction machine 7 then transports the sheet through the tension storage rack 4 and the web guiding machine 5 to the winding machine 8 to wind it up.

[0048] The foregoing has provided a detailed description of one embodiment of the present invention, but this description is merely a preferred embodiment and should not be construed as limiting the scope of the invention. All equivalent variations and modifications made within the scope of the claims of this invention should still fall within the patent coverage of this invention.
