Description

Technical Field

[0001] This utility model relates to the field of recycled plastic processing technology, specifically to a preheating device for hot melting of recycled plastic granules. Background Technology

[0002] Recycled plastic pellets are granular materials made from recycled and reprocessed plastic waste. They are widely used in various fields such as daily necessities manufacturing, building materials, auto parts, medical devices, and textiles and clothing. Before extruding recycled plastic pellets into various products through an extruder, a preheating device is needed to preheat the recycled plastic pellets to improve the hot melt effect and ensure product quality.

[0003] However, existing recycled plastic granule hot-melt preheating devices, while using rotating plates to move the granules within the device, still cause plastic to accumulate between the equally spaced rotating plates. This results in uneven preheating, where the inner layer is less effective than the outer layer. Furthermore, plastic granules can easily become stuck between the rotating plates and the inner wall of the device, affecting normal operation. Therefore, these devices present technical problems in effectively and evenly dispersing recycled plastic granules to improve and ensure optimal preheating results.

[0004] Therefore, we propose a preheating device for hot-melting recycled plastic granules to solve the above problems. Utility Model Content

This solves the problem mentioned in the background technology, where the recycled plastic granules are moved within the device by rotating and turning the rotating plates, but the plastic still accumulates between the equally spaced rotating plates, resulting in uneven preheating due to the inner layer being less effective than the outer layer. Furthermore, the plastic granules are easily stuck between the rotating plates and the inner wall of the device, affecting the normal operation of the device. This invention also fails to effectively and evenly disperse the recycled plastic granules to improve the preheating effect and ensure its effectiveness.

[0027] 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.

[0028] Example

[0029] like Figure 1-4 As shown, an embodiment of this utility model discloses a preheating device for hot-melting recycled plastic granules, comprising a frame 1, a heating box 2 disposed at the top between the inner sides of the frame 1, and a rotating shaft 10 rotatably connected at the middle position between the two sides inside the heating box 2, and further comprising:

[0030] The flap 7 is located on the outside of the rotating shaft 10; the geared motor 3 is located in the middle of one side of the heating box 2. One side of the rotating shaft 10 is connected to the output end of the geared motor 3 through the bearing, which passes through the inside of the heating box 2. After the recycled plastic granules that need to be preheated are put into the heating box 2, the heating is turned on. At the same time, the geared motor 3 located in the middle of one side of the heating box 2 is turned on to drive the rotating shaft 10 connected to its output end to rotate inside the heating box 2. When the rotating shaft 10 rotates, it drives the flap 7 to rotate and flip the recycled plastic granules for preheating.

[0031] like Figure 1-4As shown, in some embodiments, a material equalization structure is set inside the flip plate 7 and at one edge of one side. The material equalization structure includes material equalization holes 8, end face scrapers 13, and side scrapers 14. The material equalization holes 8 are set inside the flip plate 7 and are arranged at equal intervals inside the flip plate 7. When the rotating flip plate 7 flips the recycled plastic particles, the material equalization holes 8 evenly set inside it can leak through the recycled plastic particles, making the plastic particles more dispersed in the heating box 2. The end face scraper 13 is set at the outer end of one side of the flip plate 7, and the side scrapers 14 are set on both sides of one end of the flip plate 7. When the flip plate 7 rotates, the end face scraper 13 and the side scrapers 14 rotate with it and scrape the plastic particles between the side and end face of the flip plate 7 and the inner wall of the heating box 2, so as to prevent the plastic from getting stuck in the gap and affecting the stable rotation of the flip plate 7.

[0032] like Figure 1-3 As shown, in some embodiments, a feed cover plate 4 is provided at the top of the front end of the heating box 2, and a discharge cover plate 5 is provided at the bottom end of the heating box 2. An opening and closing cylinder 6 is movably hinged at the middle position of one end of the bottom of the inner side of the frame 1. The top of the opening and closing cylinder 6 is movably hinged to the outer end of the discharge cover plate 5. The opening and closing cylinder 6, which is movably hinged to the bottom of the inner side of the frame 1 and movably hinged to the outer end of the discharge cover plate 5, can control the opening and closing of the discharge cover plate 5 to prevent the particles from flowing out when preheating the recycled plastic particles, and at the same time facilitate the rapid discharge of the preheated recycled plastic particles.

[0033] like Figure 1-2 As shown, in some embodiments, temperature sensors 9 are installed on both sides of the top of the heating box 2, and the temperature sensors 9 are symmetrically arranged on the top of the heating box 2. By symmetrically arranging two sets of temperature sensors 9 on the top of the heating box 2, the temperature inside the device can be accurately monitored in real time, and the temperature can be fed back to the control center so as to adjust the heating temperature of the device to a suitable temperature for preheating the recycled plastic particles in real time.

[0034] like Figure 3 As shown, in some embodiments, a stabilizing structure is set between the middle positions on both sides of the flip plate 7 and the two sides inside the heating box 2. The stabilizing structure includes a positioning guide rail 11 and a stabilizing slide 12. The positioning guide rail 11 is set on both sides inside the heating box 2 and is fixedly connected to the heating box 2 to ensure its stability, thereby ensuring the positioning stability effect. The stabilizing slide 12 is snapped into the middle positions on both sides of the flip plate 7. The fixed connection between the stabilizing slide 12 and the flip plate 7 can ensure that it can rotate with the flip plate 7.

[0035] like Figure 3As shown, in some embodiments, the positioning guide rail 11 is annular, and the stabilizing slide 12 is arc-shaped. The stabilizing slide 12 is nested on the outside of the positioning guide rail 11, and the stabilizing slide 12 can slide on the positioning guide rail 11. When the flip plate 7 is driven to rotate and flip the recycled plastic particles, it drives the stabilizing slide 12 that is locked on both sides to rotate and slide on the annular positioning guide rail 11, thereby stabilizing the flip plate 7 and preventing the flip plate 7 from being deformed by force when flipping the recycled plastic particles, which would affect the flipping and preheating effect.

[0036] In use, open the feed cover 4 to quantitatively feed the recycled plastic granules that need to be preheated into the heating chamber 2. Then close the feed cover 4 and turn on the heating chamber 2 to preheat the recycled plastic granules. At the same time, start the geared motor 3 to drive the rotating shaft 10 to rotate inside the heating chamber 2. When the rotating shaft 10 rotates, it drives the flip plate 7 to rotate and flip the recycled plastic granules. The material distribution holes 8 set at equal intervals in the flip plate 7 allow the recycled plastic granules to pass through, making the plastic granules more dispersed in the heating chamber 2. The end shovel plate 13 and the side shovel plate 14 can rotate the flip plate 7 to rotate the material from the side. The plastic granules are scooped up from the face and end to prevent them from getting stuck in the gap between the flip plate 7 and the inner wall of the heating box 2, which would affect the stable rotation of the flip plate 7. The stabilizing slide 12 rotates and slides on the positioning guide rail 11 as the flip plate 7 rotates to stabilize the flip plate 7. At the same time, the temperature inside the device can be accurately monitored in real time by two sets of temperature sensors 9, and the temperature is fed back to the control center so that the heating temperature of the device can be adjusted in real time to the appropriate temperature for preheating the recycled plastic granules. After the recycled plastic granules are uniformly preheated in the device, the opening and closing cylinder 6 is opened to open the discharge cover 5 and the preheated recycled plastic granules can be quickly discharged.

[0037] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
