Description

Technical Field

[0001] This utility model relates to the field of TPV particle preparation technology, and in particular to an environmentally friendly and odor-neutralizing TPV particle preparation device. Background Technology

[0002] The preparation of TPV (thermoplastic vulcanizate) granules is based on dynamic vulcanization technology. Its core principle is to achieve simultaneous vulcanization and dispersion of the rubber phase in the thermoplastic matrix through a high-temperature, high-shear environment, ultimately forming a "sea-island" structure. The essence of the vulcanization reaction includes rubber vulcanization and dynamic vulcanization. Rubber vulcanization is the cross-linking reaction initiated by the vulcanizing agent of rubber molecular chains to form a three-dimensional network structure, which endows the rubber with elasticity, heat resistance and chemical resistance. Dynamic vulcanization is the simultaneous occurrence of the vulcanization reaction during the melt blending process. Under the action of shear force, the rubber phase is broken into micron-sized particles, and vulcanization cross-linking is completed at the same time.

[0003] The main steps of dynamic vulcanization include raw material blending, dynamic vulcanization process, and granulation and post-treatment. Raw material blending refers to the mixing of rubber phase, plastic phase, and additives through a twin-screw extruder. The dynamic vulcanization process uses a twin-screw extruder to provide a high-temperature (190-230℃) and high-shear environment to ensure that the rubber phase is fully vulcanized and finely dispersed. The granulation step uses an underwater pelletizing or water ring pelletizing system to avoid high-temperature particle oxidation and reduce dust generation. Particles that do not meet the particle size requirements are then removed by sieving and homogenization, and batch stability is ensured by using a homogenization chamber.

[0004] In the existing technology, TPV particles will undergo a cross-linking reaction with vulcanizing agents during the preparation process. The residual vulcanizing agents, the volatilization of plasticizers, or the oxidative degradation of rubber will all produce odors, which will cause users to experience discomfort such as dizziness and nausea. Although heat treatment can accelerate the discharge of volatiles and reduce the odor level, the heat treatment takes a long time and will affect the preparation efficiency of PV particles.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] This utility model provides a technical solution:

[0027] Please see Figures 1 to 4 An environmentally friendly, odor-free TPV pellet preparation device includes a body 1 and an input cavity 11 opened on the upper left side of the body 1. A conveying cylinder 12 is fixedly connected to the upper left side of the body 1. A top cover 13 is provided on the upper side of the conveying cylinder 12. A drive motor 14 is provided on the upper side of the top cover 13. A rotating rod 15 is fixedly connected to the output end of the drive motor 14. A feeding component 2 is provided on both the inner and outer sides of the conveying cylinder 12. The feeding component 2 includes a first rotating disk 21 fixedly connected to the outer side of the rotating rod 15.

[0028] A notch 22 is provided on the outer surface of the first rotating disk 21. A first magnetic block 23 is fixedly connected to the inner wall of the notch 22. A movable plate 24 is slidably connected to the lower right side of the top cover 13. A second magnetic block 25 is fixedly connected through the interior of the movable plate 24. Guide rods 27 are fixedly connected to both the front and rear sides of the right end of the movable plate 24. A fixed plate 26 is fixedly connected to the lower right side of the top cover 13. A tension spring 28 is fixedly connected between the movable plate 24 and the fixed plate 26. The guide rods 27 slide through the fixed plate 26. A storage tank 29 is provided on the upper side of the top cover 13. An outlet 291 is provided through the lower side of the interior of the storage tank 29.

[0029] The machine body 1 is connected to the conveying cylinder 12 through the input cavity 11. The rotating rod 15 passes through the top cover 13. The first magnetic block 23 and the second magnetic block 25 are magnetically attracted to each other. After the first rotating disk 21 rotates, it blocks the outlet 291. After the notch 22 rotates, it connects with the outlet 291.

[0030] A guide ramp 5 is fixedly connected to the lower inside of the storage tank 29. The downward slope of the guide ramp 5 faces the outlet 291. A tension spring 28 is sleeved on the outside of the guide rod 27.

[0031] A groove 3 is provided on the lower side of the storage tank 29. A slider 4 is slidably connected inside the groove 3. The slider 4 is fixedly connected to the upper side of the movable plate 24. The movable plate 24 is located to the left of the fixed plate 26.

[0032] By adopting the above technical solution, during the process of filling the raw material into the conveying cylinder 12, the drive motor 14 on the upper side of the top cover 13 will drive the rotating rod 15 to rotate, and drive the first rotating disk 21 on its outer side to rotate. When the first magnetic block 23 inside the notch 22 on the outer side of the first rotating disk 21 rotates to the position corresponding to the second magnetic block 25 inside the moving plate 24, the moving plate 24 slides in the groove 3 on the lower side of the storage tank 29 through the slider 4, and the first magnetic block 23 and the second magnetic block 25 are magnetically attracted, so that the first magnetic block 23 attracts the second magnetic block 25, and pulls the tension spring 28 fixed on the left side of the fixed plate 26 through the moving plate 24. During this process, the guide rod 27 on the right side of the moving plate 24 will slide inside the fixed plate 26. When the first magnetic block 23 attracts the second magnetic block 25, the notch 22 is connected to the storage tank 29, so that the additive inside the storage tank 29 slides to the discharge port 291 through the guide slope 5, and then is sent into the conveying cylinder 1 through the notch 22. Inside the storage tank 29, as the first rotating disk 21 continues to rotate, the notch 22 and the outlet 291 become misaligned. At this time, the additive is blocked inside the storage tank 29. After the second magnetic block 25 loses the attraction from the first magnetic block 23, the tension spring 28 pulls the moving plate 24, causing the second magnetic block 25 to quickly strike the fixed plate 26 and causing the storage tank 29 to vibrate slightly. At this time, the additive inside the storage tank 29 will also slide on the upper side of the guide slope 5 due to the slight vibration. The additive and raw materials will finally enter the machine body 1 through the input cavity 11. Since the first rotating disk 21 can make the notch 22 and the outlet 291 on the lower side of the storage tank 29 briefly connected after rotation, it is convenient to supply the additive intermittently. At the same time, after the first rotating disk 21 rotates once, the second magnetic block 25 will strike the fixed plate 26 below the storage tank 29, causing the additive inside the storage tank 29 to slide on the upper side of the guide slope 5 due to the slight vibration, thereby accelerating the discharge of the additive.

[0033] Specifically, such as Figure 2 and Figure 3 As shown, the inner and outer sides of the conveying cylinder 12 are provided with a mixing component 6, which includes a second rotating disk 61 fixedly connected to the outside of the rotating rod 15.

[0034] The upper side of the second rotating disk 61 has through holes 62 arranged in a ring array. The left and right sides of the lower end of the conveying cylinder 12 are fixedly connected to fixed disks 63. The bottom end of the rotating rod 15 is fixedly connected to a threaded post 64, which is inserted into the inside of the input cavity 11.

[0035] The left and right fixed plates 63 are located on the left and right sides of the rotating rod 15, and the second rotating plate 61 is located on the upper side of the fixed plate 63. There is a gap between the left and right fixed plates 63.

[0036] Scraper strips 65 are fixedly connected to the front and rear sides of the upper part of the outer surface of the threaded column 64. After the two scraper strips 65 rotate, they slide and press against the upper side of the two fixed discs 63 respectively.

[0037] By adopting the above technical solution, the rotating rod 15 will drive the second rotating disk 61 on its outer side to rotate while rotating. As the raw materials and additives pass through the through hole 62 on the surface of the second rotating disk 61, some of the raw materials and additives will remain above the fixed disk 63. At the same time, the second rotating disk 61 will strike the raw materials and additives with its surface and the inner wall of the through hole 62 during the rotation, so that the two are quickly mixed. The rotating rod 15 will also drive the threaded column 64 at its bottom end to rotate inside the input cavity 11. During this process, the threaded column 64 will drive the two scrapers 65 on its outer side to rotate above the two fixed disks 63 respectively. After the scrapers 65 rotate, they will push the raw materials and additives remaining above the fixed disk 63 towards the threaded column 64. After the threaded column 64 rotates, it will send the raw materials and additives into the machine body 1. Since the raw materials and additives are struck by the second rotating disk 61 after entering the inside of the conveying cylinder 12, and some of the raw materials and additives will pass through the through hole 62, the raw materials and additives will be quickly mixed. At the same time, the scrapers 65 push the raw materials and additives above the fixed disk 63, so that the two are further mixed.

[0038] Working principle: The drive motor 14 on the upper side of the top cover 13 drives the rotating rod 15 to rotate, which in turn drives the first rotating disk 21 on its outer side to rotate. When the first magnetic block 23 inside the notch 22 corresponds to the second magnetic block 25 inside the moving plate 24, the first magnetic block 23 attracts the second magnetic block 25, making the notch 22 connected to the storage tank 29. The additive inside the storage tank 29 slides through the guide slope 5 to the discharge port 291 and is discharged into the conveying cylinder 12. As the first rotating disk 21 continues to rotate, the notch 22 and the discharge port 291 are misaligned. After the second magnetic block 25 loses the attraction from the first magnetic block 23, the tension spring 28 pulls the moving plate 24. The second magnetic block 25 is rapidly struck by the fixed plate 26, causing the storage tank 29 to vibrate slightly. As the rotating rod 15 rotates, it also drives the second rotating disk 61 to rotate. As the raw materials and additives pass through the through hole 62 on the surface of the second rotating disk 61, they are struck by the surface and the inner wall of the through hole 62, causing them to mix rapidly. During this process, the threaded column 64 drives the two scrapers 65 on its outer side to rotate above the two fixed disks 63 respectively. After the scrapers 65 rotate, they push the raw materials and additives remaining above the fixed disks 63 toward the threaded column 64. After the threaded column 64 rotates, it sends the raw materials and additives into the machine body 1.

Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
