[0002] ABS plastic pellets are a commonly used thermoplastic engineering plastics, which are copolymerized by acrylonitrile, butadiene and styrene. ABS plastic has the common properties of the three components. Therefore, ABS plastic is a "tough, hard and rigid" material with easy raw materials, good comprehensive performance, low price and wide application. As a result, it has been widely used in manufacturing industries such as machinery, electrical, and ships, as well as in the chemical industry. In the production process of ABS plastic pellets, a preheating mixing device is required to fully mix the three monomers of acrylonitrile, butadiene and styrene.
[0003] However, the existing preheating mixing device still has the following defects and shortcomings in actual use:

[0005] 2. When the three monomers are stirred and mixed inside the mixing box, the raw materials will stick to the inner wall of the mixing box after melting. Sticking to the inner wall will make it unable to participate in the subsequent mixing, and the raw materials will not be fully mixed. When the mixed raw materials are discharged, the raw materials adhered to the inner wall will not be discharged, resulting in a waste of resources. Utility Model Content

[0024] The present application is described in detail below with reference to the accompanying drawings and specific implementation methods.
[0025] Example 1
[0026] like Figure 1-Figure 2As shown, a preheating and mixing device for chemical synthesis of ABS plastic pellets includes: a mixing box 1, a feeding barrel 101 arranged on one side of the top of the mixing box 1, a discharge pipe 102 arranged on one side of the bottom of the mixing box 1, a control panel 103 arranged on one side of the outer surface of the mixing box 1, an observation window 104 arranged on one side of the outer surface of the mixing box 1, a preheating component arranged inside the feeding barrel 101, used for preheating plastic pellets, and a scraping component arranged on the inner wall of the mixing box 1, used for scraping plastic on the inner wall of the mixing box 1.
[0027] Among them, reference Figure 1-Figure 3 The preheating component includes: a plurality of baffles 2 arranged inside the feed barrel 101, a plurality of discharge holes 201 opened inside the baffles 2, a plurality of heating plates a202 installed on both sides of the inner wall of the feed barrel 101, and a guide plate 3 is provided on one side of the top of the mixing box 1. The guide plate 3 is inclined and is located at the bottom of the feed barrel 101.
[0028] After the plastic pellets are put into the feed barrel 101, the control panel controls the multiple heating plates a202 to heat the plastic pellets at 160-180°C, thereby preheating the plastic pellets. At this time, the plastic pellets fall onto the baffle plate 2, and then fall from the multiple discharge holes 201 to the next baffle plate 2. The multiple baffle plates 2 and the discharge holes 201 are used to reduce the falling speed of the plastic pellets, so that the plastic pellets are fully preheated, ensuring that the plastic pellets are gradually heated up, which is conducive to the full melting of the plastic pellets, thereby improving the mixing efficiency. When the preheated plastic pellets fall from the feed barrel 101 onto the guide plate 3, the inclined guide plate 3 will guide the plastic pellets to the middle of the mixing box 1, thereby preventing the plastic pellets from being concentrated and accumulated inside the mixing box 1 and affecting the mixing.
[0029] Among them, reference Figure 1-Figure 2 A driving motor 4 is installed on the top of the mixing box 1, and a main rod 401 extending into the interior of the mixing box 1 is provided at the bottom of the driving motor 4. Multiple stirring rods 402 fixedly connected to the main rod 401 are provided on both sides of the interior of the mixing box 1, and a heating plate b403 is installed on the inner side and bottom of the inner wall of the mixing box 1.
[0030] After the plastic pellets are fed into the mixing box 1, the control panel controls the heating plate b403 to heat the plastic pellets at 180-220°C, so that the plastic pellets can melt quickly. The drive motor 4 is started while the plastic pellets are melting, and the drive motor 4 is used to make the main rod 401 drive multiple stirring rods 402 to rotate, so that the plastic pellets are fully stirred and mixed.
[0031] Among them, reference Figure 1-Figure 2 and Figure 4-Figure 5The scraping assembly includes: a rotating ring 5 arranged at the bottom of the mixing box 1, scraping strips 501 arranged on both sides of the bottom of the rotating ring 5, and the scraping strips 501 are attached to the inner wall of the mixing box 1, a servo motor 6 is installed on one side of the top of the mixing box 1, and the bottom of the servo motor 6 is connected to a transmission rod 601 extending to the inside of the mixing box 1, and the bottom of the transmission rod 601 is fixedly connected to a gear 602, and teeth 502 are arranged in a circle on the inner side of the rotating ring 5, and the gear 602 is meshed with the teeth 502.
[0032] While stirring the plastic particles, the servo motor 6 is started through the control panel, and the transmission rod 601 is used to drive the gear 602 to rotate by the servo motor 6. Since the gear 602 is meshed with the teeth 502 on the inner side of the rotating ring 5, the rotating ring 5 can be driven to rotate. The rotating ring 5 drives the scraper 501 on the inner side of the bottom to rotate inside the mixing box 1. Since the scraper 501 is attached to the inner wall of the mixing box 1, the plastic fluid adhering to the inner wall can be scraped off while the scraper 501 rotates, so that the plastic fluid can be fully mixed. At the same time, when the mixed plastic fluid needs to be discharged through the discharge pipe 102, the scraper 501 scrapes off the plastic fluid on the inner wall to avoid plastic residue and waste of resources.
[0033] Among them, reference Figure 2 and Figure 4-Figure 5 The outer side of the rotating ring 5 is fixedly connected with a limiting ring 503, the inner wall of the mixing box 1 is provided with an annular groove 105, and the limiting ring 503 is slidably connected with the inside of the annular groove 105. The gear 602 drives the rotating ring 5 to rotate, and the rotating ring 5 will drive the limiting ring 503 on its outer side to rotate inside the annular groove 105. The limiting ring 503 and the annular groove 105 are used to fix the position of the rotating ring 5, thereby avoiding the position deviation of the rotating ring 5 and preventing the teeth 502 from separating from the gear 602.
[0034] The control panel is used to control the start and stop of the heating plate a202, the drive motor 4, the heating plate b403 and the servo motor 6, and the control panel, the heating plate a202, the drive motor 4, the heating plate b403 and the servo motor 6 are all powered by an external power supply, and the control procedures involved in the utility model can be implemented by those skilled in the art according to the same or similar principles in the prior art, and this part is not the innovation of the utility model.
[0035] The device preheats the plastic pellets sufficiently through the preheating component, ensuring that the plastic pellets are gradually heated up, which is conducive to the full melting of the plastic pellets, thereby improving the mixing efficiency, and the plastic fluid adhering to the inner wall can be scraped off through the scraping component, so that the plastic fluid can be fully mixed, and at the same time, plastic residue can be avoided during discharge. Specific implementation method: After the plastic pellets are put into the feed barrel 101, the control panel controls the multiple heating plates a202 to heat the plastic pellets at 160-180°C, thereby preheating the plastic pellets. At this time, the plastic The pellets fall onto the baffle plate 2, and then fall from the multiple discharge holes 201 to the next baffle plate 2. The multiple baffle plates 2 and the discharge holes 201 are used to reduce the falling speed of the plastic pellets, so that the plastic pellets are fully preheated, ensuring that the plastic pellets are gradually heated up, which is conducive to the full melting of the plastic pellets, thereby improving the mixing efficiency. When the preheated plastic pellets fall from the feed barrel 101 onto the guide plate 3, the inclined guide plate 3 will guide the plastic pellets to the middle of the mixing box 1, thereby preventing the plastic pellets from being concentrated and accumulated inside the mixing box 1 to affect the mixing.
[0036] While stirring the plastic particles, the servo motor 6 is started through the control panel, and the transmission rod 601 is used to drive the gear 602 to rotate by the servo motor 6. Since the gear 602 is meshed with the teeth 502 on the inner side of the rotating ring 5, the rotating ring 5 can be driven to rotate. The rotating ring 5 drives the scraper 501 on the inner side of the bottom to rotate inside the mixing box 1. Since the scraper 501 is attached to the inner wall of the mixing box 1, the plastic fluid adhering to the inner wall can be scraped off while the scraper 501 rotates, so that the plastic fluid can be fully mixed. At the same time, when the mixed plastic fluid needs to be discharged through the discharge pipe 102, the scraper 501 scrapes off the plastic fluid on the inner wall to avoid plastic residue and waste of resources.
