[0002] Inflatable boats are a common type of water transportation, widely used for water patrols, flood control and disaster relief, outdoor adventures, and extreme water sports. Currently, common materials for inflatable boats include fiberglass, Hypalon rubber, and PVC. Previously, inflatable boats were mostly made of Hypalon rubber, which has good UV resistance, temperature resistance, and wear resistance, with a lifespan of over ten years. Its disadvantages are the expensive coating materials, resulting in a high price and an unattractive appearance. Modern inflatable boats are mainly made of PVC. This material is inexpensive, allows for color mixing and matching, and has a stylish appearance, but its lifespan is slightly shorter. Therefore, designing a method for manufacturing an anti-aging, airtight material for inflatable boats is essential. Summary of the Invention

[0005] The adjustable crusher includes a crushing chamber with two grooves on one side of its outer wall. A door is located on the side of the crushing chamber near the grooves. A collection box is located at the bottom of the crushing chamber, and a feed pipe is fixedly connected to the top of the crushing chamber. A first filter plate is vertically and movably mounted at the center of the inner wall of the crushing chamber, with several first through holes inside. A support platform is located on one side of the inner wall of the crushing chamber, supporting one end of the first filter plate. A protective shell is fixedly connected to one side of the inner wall of the crushing chamber, and a vibration mechanism is located inside the protective shell. A second filter plate is horizontally and movably mounted on top of the first filter plate, with several second through holes inside. A spring is fixedly connected to the bottom of the end of the first filter plate away from the support platform, and a fixed platform is fixedly connected to the bottom of the spring. An equipment box is fixedly connected to the side of the outer wall of the crushing chamber away from the support platform, and an electric telescopic rod is fixedly connected to the side of the inner wall of the equipment box away from the support platform. A crushing blade body is located at the top of the inner wall of the crushing chamber.

[0006] The side of the box door closest to the crushing box is slidably connected to two slides.

[0012] Compared with existing technologies, the method for manufacturing this anti-aging airtight material for assault boats has the following advantages:

[0013] 1. The anti-aging airtight material for inflatable boats obtained in this invention has high strength, anti-aging properties, and good airtightness, which will greatly improve the equipment level for water patrol, flood control and disaster relief, outdoor exploration, and extreme water sports, and has good potential for widespread application.

[0014] 2. The present invention includes an electric telescopic rod, a first filter plate, a second filter plate, a first through hole, and a second through hole. The electric telescopic rod drives the second filter plate to slide on the top of the first filter plate, thereby changing the positional relationship between the first through hole and the second through hole, so that the first through hole and the second through hole are staggered, thereby limiting the size of the nitrile elastomer particles that can pass through, and facilitating the control of the fineness of the pulverized nitrile elastomer particles.

[0023] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings to further illustrate the technical solutions of the present invention. However, the present invention is not limited to these embodiments.

[0024] The method for manufacturing this anti-aging airtight material for assault boats is characterized by the following steps: S1, raw material preparation: including the following raw materials in parts by weight, comprising 100-120 parts of PVC resin, 10-24 parts of nitrile elastomer, 20-30 parts of liquid plasticizer, 5-15 parts of high-stability color paste, 0.4-1.2 parts of UV absorber, and 2-3 parts of antioxidant; S2, pulverizing the nitrile elastomer into granules using an adjustable pulverizer; selecting the desired high-stability color paste, adding the high-stability color paste to the liquid plasticizer and stirring thoroughly, then mixing thoroughly with the PVC resin, then mixing thoroughly with the granulated nitrile elastomer, finally adding the UV absorber and antioxidant and mixing evenly to obtain a mixture, pre-plasticizing after blending in a high-speed mixer, then adding to an extruder for granulation, and finally calendering through a calender to obtain the anti-aging airtight material for assault boats;

[0025] This product is made using PVC calendering technology, resulting in a thin finished product with high elasticity and high toughness.

[0026] Unlike the traditional method of adding color powder to PVC formulations, a highly stable color paste is added to improve the color fastness to sunlight. This paste has excellent compatibility with PVC formulations and can keep the product's color bright and new, and prevent fading for a long time.

[0027] The process of blending and calendering PVC resin and nitrile elastomer is adopted. The PVC resin and nitrile elastomer are in the optimal ratio of 10:2 to achieve the best compatibility between the continuous phase and the dispersed phase of the two components, and finally achieve the product with good flexibility.

[0028] By studying the aging mechanism of PVC, a certain proportion of UV absorbers and antioxidants were added to the formula, which greatly improved the anti-aging performance of this product compared with traditional products and significantly extended its service life.

[0029] Reference Figure 1-6This adjustable pulverizer includes a pulverizing chamber 1. Two grooves 2 are formed on one side of the outer wall of the pulverizing chamber 1. A door 3 is located on the side of the pulverizing chamber 1 near the grooves 2. A collection box 4 is located at the bottom of the pulverizing chamber 1. A feed pipe 5 is fixedly connected to the top of the pulverizing chamber 1. A first filter plate 6 is vertically and movably arranged at the center of the inner wall of the pulverizing chamber 1. The first filter plate 6 has several first through holes 7 inside. A support platform 37, which is a perforated plate, is located on one side of the inner wall of the pulverizing chamber 1 to support one end of the first filter plate 6. A protective device is fixedly connected to one side of the inner wall of the pulverizing chamber 1. The housing 8 contains a vibration mechanism. A second filter plate 10 is horizontally movable on the top of the first filter plate 6. The second filter plate 10 has several second through holes 11 inside. A spring 12 is fixedly connected to the bottom of the end of the first filter plate 6 away from the support platform 37. A fixed platform 13 is fixedly connected to the bottom of the spring 12. An equipment box 14 is fixedly connected to the outer wall of the crushing box 1 on the side away from the support platform 37. An electric telescopic rod 15 is fixedly connected to the inner wall of the equipment box 14 on the side away from the support platform 37. A crushing blade body 16 is set on the top of the inner wall of the crushing box 1. The device drives the second filter plate 10 to slide on the top of the first filter plate 6 through the electric telescopic rod 15, thereby changing the positional relationship between the first through holes 7 and the second through holes 11, so that the first through holes 7 and the second through holes 11 are staggered, thereby limiting the size of the nitrile elastomer particles that can pass through, and facilitating the control of the fineness of the crushed nitrile elastomer particles.

[0030] The door 3 is slidably connected to two chute 2 on the side near the crushing chamber 1. When the user needs to remove the crushed nitrile elastomer particles, they only need to slide the door 3 upward along the chute 2 to open the door 3 and remove the collection box 4. No manual secondary screening is required, saving a lot of time and manpower. The first filter plate 6 is slidably connected to the inner wall of the crushing chamber 1. The vibration mechanism drives the first filter plate 6 to vibrate, thereby driving the second filter plate 10 to vibrate. This facilitates the re-vibration of nitrile elastomers that do not meet the fineness requirements and allows them to be crushed again by the crushing blade body 16, greatly improving the crushing efficiency of the device. The second filter plate 10 penetrates the side wall of the crushing chamber 1 and is fixedly connected to the telescopic end of the electric telescopic rod 15. The top of the first filter plate 6 and the bottom of the second filter plate 10 are attached together. Several first through holes 7 and several second through holes 11 correspond one-to-one and are the same size. The cross-sections of the first through holes 7 and the second through holes 11 are both rectangular. The electric telescopic rod 15 drives the second filter plate 10 to move, thereby changing the positional relationship between the first through holes 7 and the second through holes 11, so that the first through holes 7 and the second through holes 11 are staggered. The area of ​​the through holes where the first through holes 7 and the second through holes 11 intersect is the size that the nitrile elastomer particles can pass through, thus facilitating the control of the size of the nitrile elastomer particles that pass through.

[0031] The vibration mechanism includes a drive motor 9, a vibrating head 21, a single-sided rack 17, a single-sided rack 27, a double-sided rack 31, an adjusting seat 26, and an auxiliary seat 18. The protective housing 8 has three vertically arranged guide sections 8c, 8a, and 8b, with guide section 8c located between guide sections 8a and 8b. The vibrating head 21 is vertically slidably connected to guide section 8c and can abut against the first filter plate 6. The drive motor 9 is installed inside the protective housing 8, and its output shaft is horizontally positioned. The end of the output shaft of the drive motor 9 is connected to a power shaft 29. The power shaft 29 and the eccentric... The counterweight linkage block 28 is fixedly connected. The eccentric counterweight linkage block 28 is rotatably connected to the lower end of the connecting part 30 via a rotating shaft 1. The upper end of the connecting part 30 is rotatably connected to the middle of the swinging part 22 via a rotating shaft 2. One end of the swinging part 22 has an arc-shaped active gear disk 23, and the other end of the swinging part 22 has an arc-shaped support gear disk 24. The double-sided rack 31 is vertically connected to the vibrating head 21, and one side of the teeth of the double-sided rack 31 meshes with the arc-shaped active gear disk 23. The single-sided rack 17 is vertically mounted on the guide part 2 8a. The auxiliary seat 18 is vertically slidably connected to the guide part 2 8a. An auxiliary gear 19 is mounted on the auxiliary seat 18, and the auxiliary gear 19 meshes with the single-sided rack 17. The teeth of the first rack 17 mesh with the teeth on the other side of the double-sided rack 31. The adjusting seat 26 is vertically slidably connected to the guide part 3 8b. A locking screw 25 is horizontally threaded onto the adjusting seat 26. The second single-sided rack 27 is vertically mounted on the adjusting seat 26, and the teeth of the second single-sided rack 27 mesh with the arc-shaped support gear plate 24. An elastic storage bladder 20 is installed inside the protective shell 8. The elastic storage bladder 20 is a commercially available product that can automatically recover without being subjected to external force. An air inlet pipe 33 is connected to the elastic storage bladder 20, and the air inlet pipe 33 has a one-way valve 32. The protective shell 8 is also connected to an air outlet pipe 34, which is connected to an air nozzle 36. The air nozzle 36 is installed on the protective shell 8. An extrusion block 35 that cooperates with the elastic storage bladder 20 is also installed on the auxiliary seat 18. With this structure, the vibrating head 21 can be repeatedly slid in the vertical direction by driving the motor 9. The vibrating head 21 repeatedly impacts the first filter plate 6 to make it vibrate. At the same time, the height position of the adjusting seat 26 can be adjusted to change the highest position of the vibrating head 21, thereby changing the impact intensity. The air nozzle 36 is used to blow away the nitrile elastomer particles on the upper part of the protective shell 8 to prevent them from accumulating on the protective shell 8.

[0032] Working principle: First, the user puts the nitrile elastomer into the crushing box 1 through the feed pipe 5. The crushing blade body 16 is activated to crush the nitrile elastomer. The user controls the electric telescopic rod 15 to drive the second filter plate 10 to slide on top of the first filter plate 6, thereby changing the positional relationship between the first through hole 7 and the second through hole 11, thus changing the size of the nitrile elastomer particles passing through the two filter plates. At the same time, the vibration mechanism inside the protective shell 8 is activated, causing the first filter plate 6 to vibrate. The vibration is transmitted to the second filter plate 10, and the surface of the second filter plate 10 vibrates, thereby lifting the nitrile elastomer that is not large enough to pass through the first through hole 7 and the second through hole 11, and continuing to be crushed by the crushing blade body 16 until the nitrile elastomer particles are crushed enough to pass through the first through hole 7 and the second through hole 11 and can smoothly enter the collection box 4. Finally, the user only needs to slide the box door 3 upward along the slide 2 to open the box door 3 and take out the collection box 4 to obtain the crushed nitrile elastomer particles. The aforementioned crushing blade body 16 is existing technology and will not be described in detail here. A specially designed crusher can be used to adjust and change the size of nitrile elastomer particles according to the requirements of the entire manufacturing process.
