For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0024] Please see Figure 1-5 An embodiment of this utility model provides a plastic product raw material drying device, including a drying outer cylinder 1. The drying outer cylinder 1 has a hollow structure design. A plurality of heating rods 2 are inserted inside the drying outer cylinder 1. The plurality of heating rods 2 are distributed in a circumferential manner at equal intervals through the central point of the drying outer cylinder 1. A drying inner cylinder 3 is fixedly installed inside the drying outer cylinder 1. A plurality of uniformly distributed graphite heat-conducting blocks 4 are fixedly installed between the drying inner cylinder 3 and the drying outer cylinder 1.

[0025] This structural design allows the heating rod 2 to heat the interior of the drying outer cylinder 1. The heating effect of the heating rod 2 can be efficiently conducted through the graphite heat-conducting block 4. Thus, the heating rod 2 can quickly heat the drying inner cylinder 3 through the graphite heat-conducting block 4, thereby providing the necessary temperature conditions for drying the raw materials inside the heating inner cylinder 3.

[0026] The heating rods 2 of this utility model are designed in a circumferential arrangement with equal spacing, which can effectively improve the drying uniformity inside the drying inner cylinder 3, and have a fully enclosed temperature drying effect. The temperature distribution during drying is more uniform, which can effectively improve the drying uniformity of plastic raw materials and has good practicality.

[0027] Inside the drying outer cylinder 1, a sealing cover 5 is fixedly installed. A material equalization motor 6 is fixedly installed at the center of the upper surface of the sealing cover 5 by fixing bolts. The output shaft of the material equalization motor 6 is fixedly connected to a material equalization rod 7. Several evenly distributed material equalization paddles 8 are fixedly installed on the outside of the material equalization rod 7. The material equalization paddles 8 adopt a wave-shaped structure design.

[0028] Based on the above structure, this utility model utilizes a material-leveling motor 6 for operation. When the motor 6 is operating, it drives the bottom material-leveling rod 7 to rotate via its output shaft. As the rod 7 rotates, the external material-leveling blades 8 rotate synchronously. This rotating blades 8 uniformly agitate the raw materials inside the drying cylinder 3, effectively preventing the accumulation of raw materials within the cylinder. Combined with the evenly distributed heating rods 2, this effectively improves the uniformity of raw material drying for plastic products, resulting in a more even drying process. This effectively prevents the raw materials from becoming over-dry or under-drying, enhancing practicality and improving the drying quality of raw materials for plastic products.

[0029] In this embodiment, to facilitate the injection of raw materials for plastic products, injection ports 9 are fixedly installed on both sides of the outer wall of the drying outer cylinder 1. One end of the injection port 9 passes through the drying outer cylinder 1 and is interconnected with the drying inner cylinder 3. A connecting flange is provided on the outside of the injection port 9, so that plastic raw materials can be injected through the injection port 9. The connecting flange can be used to easily connect to external injection pipes, thereby facilitating the automated injection of raw materials and ensuring normal use.

[0030] In this embodiment, in order to improve the structural strength of the outer wall of the drying outer cylinder 1, an outer protective net 10 is fixedly installed on the outer wall of the drying outer cylinder 1. The outer protective net 10 is made of aluminum alloy material. The outer protective net 10 can provide a certain protection for the outer wall of the drying outer cylinder 1 and has good practicality.

[0031] In this embodiment, a discharge seat 11 is fixedly installed at the bottom of the drying outer cylinder 1, and a discharge port 12 is fixedly installed on the lower surface of the discharge seat 11.

[0032] Among them, the discharge port 12 is interconnected with the interior of the drying inner cylinder 3, and the discharge port 12 adopts a conical structure design;

[0033] In actual use, the inside of the discharge port 12 is filled with a sealing plug, which can seal the bottom of the raw material inside during drying to prevent the raw material from flowing out. When it is necessary to discharge the material, the sealing plug inside the discharge port 12 is removed to complete the discharge of the raw material inside.

[0034] In this embodiment, in order to improve the structural stability of the bottom of the drying device, a number of equally spaced circumferentially distributed lower support columns 13 are fixedly installed on the lower surface of the bottom end of the discharge seat 11, and a lower base 14 is fixedly installed between the bottom ends of the number of lower support columns 13.

[0035] Working principle: When in use, the plastic raw materials to be dried can be injected through the injection port 9. The injected raw materials can enter the interior of the drying inner cylinder 3. At this time, the heating rods 2 set in the cylinder can work. The heating rods 2 can heat the interior of the drying outer cylinder 1. The heating effect of the heating rods 2 can be efficiently conducted through the graphite heat conduction block 4. Thus, the heating rods 2 can quickly heat the drying inner cylinder 3 through the graphite heat conduction block 4, thereby allowing the raw materials inside the heating inner cylinder 3 to undergo high-temperature drying.

[0036] The heating rods 2 of this utility model are designed in a circumferential arrangement with equal spacing, which can effectively improve the drying uniformity inside the drying inner cylinder 3, and have a fully enclosed temperature drying effect. The temperature distribution during drying is more uniform, which can effectively improve the drying uniformity of plastic raw materials and has good practicality.

[0037] Meanwhile, this utility model utilizes a material-leveling motor 6. When the motor 6 is operating, it drives the material-leveling rod 7 at the bottom to rotate via its output shaft. As the rod 7 rotates, the material-leveling discs 8 on its exterior rotate synchronously. This rotating discs 8 uniformly agitate the raw materials inside the drying cylinder 3, effectively preventing the accumulation of raw materials within the cylinder. Combined with the evenly distributed heating rods 2, this effectively improves the uniformity of raw material drying for plastic products, resulting in a more even drying process. This effectively prevents the raw materials from becoming over-dry or under-drying, enhancing practicality and improving the drying quality of raw materials for plastic products.

[0038] After drying, the raw material can be discharged through the discharge port 12, thus completing the high-temperature drying of the raw material for plastic products and ensuring normal use.

[0039] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
