DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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 creative work are within the scope of protection of the present invention.

[0032] like Figures 1 to 6 As shown, a method for preparing a coating material for rehabilitation training equipment is characterized in that the preparation method comprises the following steps:

[0033] S1. Put 100 parts of PVC resin powder, 65 parts of plasticizer, 2.5 parts of stabilizer, 10 parts of calcium powder, 10 parts of elastic agent, 0.3 parts of antioxidant, 0.4 parts of ultraviolet absorber, 0.4 parts of mildew and antibacterial agent, 3.478 parts of titanium dioxide, 0.474 parts of blue colorant and 0.04 parts of red colorant into a blender by high-speed stirring and mix well.

[0034] The materials in S2 and S1 are then subjected to internal mixing, open mixing, filtering, calendering, cooling, trimming, curling and other processes to obtain a PVC film layer;

[0035] S3, according to the mass proportion, 120 parts of EPVC paste resin, 140 parts of plasticizer and 40 parts of adhesive are stirred at high speed to form a uniform thick slurry;

[0036] S4, using a polyester woven fabric with a linear density of 840D×840D and a width of 18×18 strands / inch as a base fabric layer;

[0037] S5, evenly coating the slurry in S3 on the base fabric in S4, and drying in an oven to form a PVC coating;

[0038] S6, heating and laminating the base fabric with PVC coating in S5 and the PVC film in S2 to form a composite coated fabric;

[0039] The multi-layer composite coated fabric in S7 and S6 is then rolled up as a finished product after being embossed, cooled, trimmed, and finished.

[0040] The elastic agent component in step S1 is nitrile rubber; the stabilizer in step S1 is barium zinc stabilizer; the ultraviolet absorber in step S1 is 2-hydroxy-4-n-octyloxybenzophenone; the mildew and antibacterial agent in step S1 is N-(trichloromethylthio)phthalimide; and the antioxidant in step S2 is phenol-free phosphite.

[0041] The plasticizer used in the PVC film formula is an environmentally friendly plasticizer that meets various environmental protection requirements. The addition of elastic agents and low-temperature resistant plasticizers ensures a good touch even in the cold winter. The surface is printed with rough textures, which has an anti-slip effect to prevent slipping and injuries during rehabilitation training. The addition of antioxidants, ultraviolet absorbers, and mildew and antibacterial agents can make the material resistant to aging, mildew, antibacterial, and ultraviolet rays. The product is durable and easy to clean. After use, simply wipe the coating of the sports equipment with water. Adding a layer of coating material on the surface of the material can effectively improve the working safety and stability of the equipment, allowing rehabilitators to exercise with more confidence.

[0042] Specifically, if Figures 1 to 6 As shown, the embossing device in S7 includes, in order of processing, an unwinding roller 2, a first conveying belt 3, a bottom conveying mechanism, an embossing mechanism, a second conveying belt 6 and a winding roller 7;

[0043] The bottom conveying mechanism includes a first guide roller 41, a conveying frame 42, a third conveyor belt 43 and a second guide roller 44. A first extension frame 421 is symmetrically installed on one side of the conveying frame 42, and the first guide roller 41 is transmission-connected to the first extension frame 421. A first rotating wheel 423 is symmetrically arranged on the conveying frame 42, and the first rotating wheel 423 drives the first guide roller 41 to rotate through a first transmission belt 45; a second extension frame 422 is symmetrically installed on the other side of the conveying frame 42, and the second guide roller 44 is transmission-connected to the second extension frame 422. A second rotating wheel 424 is symmetrically arranged on the other side of the conveying frame 42, and the second rotating wheel 424 drives the second guide roller 44 to rotate through a second transmission belt 46; two first driving motors 47 are also installed on one side of the conveying frame 42, and the two first driving motors 47 are transmission-connected to the third conveyor belt 43, which is conducive to automatic conveying of film materials, improving the conveying and embossing efficiency of film materials, and automatic conveying.

[0044] The embossing mechanism includes a top frame plate 51, a first lifting motor 52, an embossing box 53, a lifting embossing frame 54 slidably arranged in the embossing box 53, and an embossing roller 55 on the embossing frame. The first lifting motor 52 is installed below the top frame plate 51, and the embossing box 53 is fixed below the first lifting motor 52. A plurality of first sliding holes 56 matching the number of embossing rollers 55 and allowing the embossing rollers 55 to move upward or downward are arranged at the bottom of the embossing box 53. The lifting embossing frame 54 is slidably matched with the first sliding holes 56. The lifting embossing frame 54 is transmission-connected with the embossing roller 55, and the lowest end of the embossing roller 55 abuts against the upper surface of the film material.

[0045] By adopting the above structure, a plurality of liftable embossing rollers 55 are arranged front and back on the embossing box 53. These embossing rollers 55 adopt different types of texture patterns, which is conducive to facilitating the corresponding correct embossing roller 55 according to the type of embossing required for the film material, while the other embossing rollers 55 are lifted upward. Several embossing rollers 55 can be arranged and combined. For example, among the four embossing rollers 55, the first and third embossing rollers 55 are embossing rollers 55 of the same type, and the second and fourth embossing rollers 55 are embossing rollers 55 of the same type. When one of the types of embossing rollers 55 is needed, the lifting embossing frame 54 on the embossing roller 55 can be lowered to the upper surface of the film material on the conveying frame 42, which is conducive to automatic and flexible adjustment of embossing rollers 55 of different types, and the practicality is greatly improved. At the same time, a variety of different embossing types can be flexibly processed on one device, and multiple devices are not required for processing, which greatly reduces the processing cost of the device. In addition, the embossing is automatic and has a high degree of mechanization.

[0046] Specifically, Figures 1 to 6As shown, the embossing box 53 also includes a plurality of controllers 531 matched with the embossing rollers 55, a plurality of hydraulic cylinders 532 matched with the embossing rollers 55 and a plurality of driving chambers 533 matched with the embossing rollers 55. The controllers 531 are arranged and installed above the embossing box 53. The hydraulic cylinders 532 are installed in the driving chambers 533. The controller 531 is connected to the hydraulic cylinders 532 through connecting lines. An installation box 534 is fixed on the piston rod of the hydraulic cylinder 532. A mounting block 535 is limit-connected in the installation box 534. A connecting rod 536 is fixed to the bottom of the mounting block 535. The connecting rod 536 is connected to the lifting embossing frame 54.

[0047] The controller 531 in the embossing box 53 controls the hydraulic cylinder 532 to drive the installation box 534 connected to the piston rod of the hydraulic cylinder 532 to lift up or move downward, thereby driving the embossing roller 55 on the lifting embossing frame 54 to lift up or move downward for embossing, which is beneficial for a single controller 531 to control a single embossing roller 55, greatly enhancing the adjustable plasticity and practicality of the device. At the same time, the sliding setting of the sliding hole and the lifting embossing frame 54 is beneficial to prevent the embossing roller 55 and the lifting embossing frame 54 from shifting during embossing and when moving upward and downward, greatly improving the embossing effect and quality; at the same time, the installation block 535 is detachably connected to the installation box 534, which is beneficial for flexible replacement of embossing rollers 55 of different models and convenient disassembly and assembly.

[0048] like Figures 1 to 6 As shown, first threaded holes 5341 are provided on both sides of the installation box 534, and second threaded holes 5351 are provided on both sides of the installation block 535. Threaded rods 537 are connected through the installation box 534 and the installation block 535. The threaded rods 537 pass through and are threadedly connected to the first threaded holes 5341 of the installation box 534 and the second threaded holes 5351 of the installation block 535, and are fixed by hexagonal nuts 538. By having a plurality of threaded rods 537 pass through the installation box 534 and the installation block 535, the installation block 535 in the installation box 534 can be quickly fixed and clamped, and fixed by the hexagonal nuts 538, the structure is stable, the connection is simple, the fixation is more reliable, and it is also very convenient to disassemble, install and replace.

[0049] like Figures 1 to 6 As shown, first sliding parts 81 are installed on the left and right sides of the lifting embossing frame 54 , and first sliding grooves 82 are opened on the left and right sides of the first sliding hole 56 , and the first sliding part 81 and the first sliding groove 82 are slidably matched.

[0050] The first sliding portion 81 and the first sliding groove 82 slide together to facilitate the lifting and lowering of the lifting embossing frame 54 at the bottom of the embossing box 53, thereby preventing the embossing roller 55 and the lifting embossing frame 54 from deviating during embossing and when moving up and down, thereby greatly improving the embossing effect and quality.

[0051] like Figures 1 to 6 As shown, a plurality of second sliding parts 83 are installed on the front and rear sides of the lifting embossing frame 54, and a plurality of second sliding grooves 84 matching the second sliding parts 83 are opened on the front and rear sides of the first sliding hole 56, and the second sliding parts 83 slide in cooperation with the second sliding grooves 84.

[0052] The second sliding portion 83 and the second sliding groove 84 slide together to facilitate the lifting and lowering of the lifting embossing frame 54 at the bottom of the embossing box 53, thereby preventing the embossing roller 55 and the lifting embossing frame 54 from deviating during embossing and when moving upward or downward, thereby greatly improving the embossing effect and quality.

[0053] like Figures 1 to 6 As shown, the installation box 534 is provided with a first groove 85, and the front and rear groove walls of the first groove 85 have a third sliding portion 851. The installation block 535 is provided with a third sliding groove 852, and the third sliding portion 851 is slidably matched with the third sliding groove 852.

[0054] Through the sliding cooperation between the third sliding part 851 and the third sliding groove 852, when installed in the first groove 85 of the installation box 534, the limiting snap-in effect can be enhanced. After the threaded rod 537 is fixed to the installation box 534 and the installation block 535, it is beneficial to enhance the limiting snap-in effect. If it needs to be removed, it can also be removed more conveniently, which is more practical.

[0055] like Figures 1 to 6 As shown, second mounting plates 91 are installed on both the front and rear sides of the embossing box 53 , a second lifting motor 92 is fixed on the second mounting plate 91 , and a limiting roller 93 is installed on the lifting rod of the second lifting motor 92 .

[0056] By providing limiting rollers 93 on the front and rear sides of the embossing box 53 and cooperating with the first guide roller 41 and the second guide roller 44, it is beneficial to keep the film material horizontally transported on the device, prevent angle and direction deviation, and improve the efficiency and quality of film embossing.

[0057] like Figures 1 to 6 As shown, a first tensioning roller 21 is further provided between the unwinding roller 2 and the first conveyor belt 3, and a second tensioning roller 22 is further provided between the winding roller 7 and the second conveyor belt 6. By providing the first tensioning roller 21 and the second tensioning roller 22, the tension of the film material is ensured to prevent the film material from slipping or loosening.

[0058] like Figures 1 to 6 As shown, the left and right sides of the conveying frame 42 are also provided with protective plates 425. By providing the protective plates 425, if the conveying direction of the film material deviates, it is helpful to block and protect the film material so that it does not fall out of the device, thereby playing a protective role.

[0059] It should be noted that all directional indications in the embodiments of the present invention (such as up, down, left, right, front, back, etc.) are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0060] In addition, the descriptions of "first", "second", etc. in the present invention are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. At the same time, the meaning of "and / or" appearing in the full text is that it includes three schemes.
