Description

Technical Field

[0001] The utility model relates to the field of waste plastic recycling, in particular to a hot melting device for waste plastic recycling. Background Art

[0002] Waste plastics, more formally known as post-consumer plastic waste, refer to discarded plastic products after consumption or use.

[0003] In the process of waste plastic recycling, a hot melting device is needed to perform hot melting treatment on waste plastics. Before the waste plastics are hot melted, the staff places the waste plastics into the placement frame on the hot melting device, and then the crushing blades inside the placement frame crush the waste plastics, making the waste plastics broken into smaller blocks for subsequent hot melting treatment. The crushed waste plastics fall downward into the hot melting device and are subjected to high-temperature hot melting to be converted into reusable plastic raw materials. However, during the crushing process of the waste plastics, there are still some large pieces of waste plastics that are not fully crushed. Since there is no interception net in the placement frame, the uncrushed large pieces of waste plastics directly fall downward to the feed inlet of the hot melting device, resulting in the blockage of the feed inlet of the hot melting device. Once the feed inlet is blocked, the newly crushed and smaller waste plastics cannot smoothly enter the hot melting device for hot melting, thus seriously affecting the subsequent hot melting operation efficiency.

[0004] In view of the above problems, it is necessary to design a hot melting device for waste plastic recycling that can intercept larger pieces of waste plastics. Content of the Utility Model

[0005] In order to overcome the defect that the uncrushed large pieces of waste plastics directly fall downward to the feed inlet of the hot melting device, resulting in the blockage of the feed inlet of the hot melting device, the utility model provides a hot melting device for waste plastic recycling.

[0006] The technical implementation scheme of the utility model is as follows: A hot melting device for waste plastic recycling includes a support frame, a hot melting machine, a placement frame, a motor, a rotating rod, stirring paddles, a cylinder and a pressing plate. The hot melting machine is installed on the upper part of the support frame, the placement frame is connected to the support frame, the lower part of the placement frame communicates with the hot melting machine, a motor is installed inside the placement frame, the lower end of the output shaft of the motor is connected to the rotating rod, stirring paddles are connected to the rotating rod, a cylinder is installed on the right side of the support frame, the left side of the telescopic end of the cylinder is connected to the pressing plate, the pressing plate is slidably matched with the rear side inside the hot melting machine, and it further includes an interception net. The interception net is connected inside the placement frame and is located below the stirring paddles.

[0007] In a preferred embodiment of the utility model, it further includes a fixing frame, a blocking rod and an elastic member. The rotating rod is connected with the fixing frame, a plurality of blocking rods are slidably connected to the fixing frame at equal intervals, and an elastic member is connected between the blocking rod and the fixing frame.

[0008] In a preferred embodiment of the present utility model, it further includes a connecting rod and a scraper. The lower end of the rotating rod is connected to the connecting rod, and the connecting rod is connected to the scraper.

[0009] In a preferred embodiment of the present utility model, it further includes a limiting plate. The left side of the upper part of the support frame is connected to the limiting plate.

[0010] In a preferred embodiment of the present utility model, one side of the scraper close to the placing frame is an inclined surface.

[0011] In a preferred embodiment of the present utility model, the stirring paddle is made of stainless steel.

[0012] Compared with the prior art, the present utility model has the following advantages: By setting the interception net, when larger pieces of waste plastics cannot directly pass through the interception net, they will be temporarily intercepted, preventing the larger pieces of waste plastics from directly falling and blocking the discharge port of the placing frame, resulting in smaller pieces of waste plastics that fall later not being able to fall into the hot melt machine, which is likely to affect the subsequent hot melting operation of waste plastics.

[0020] It should first be pointed out that in the embodiments described differently, the same components are provided with the same reference numerals or the same component names. Among them, the disclosure contained in the entire specification can be meaningfully applied to the same components with the same reference numerals or the same component names. The positional descriptions selected in the specification, such as up, down, lateral, etc., also refer to the directly described and illustrated drawings and are meaningfully applied to the new positions when the positions change.

[0021] Example: A hot-melting device for recycling waste plastics, as Figures 1-6 shown, includes a support frame 1, a hot-melting machine 2, a placement frame 3, a motor 4, a rotating rod 5, a stirring paddle 6, an intercepting net 7, a fixing frame 8, a blocking rod 9, an elastic member 10, a connecting rod 11, a scraping plate 12, a cylinder 13, a pressing plate 14 and a limiting plate 15. The upper part of the support frame 1 is equipped with a hot-melting machine 2 for hot-melting waste plastics. The support frame 1 is connected with a placement frame 3. The lower part of the placement frame 3 communicates with the hot-melting machine 2. The placement frame 3 is used to place the waste plastics to be processed. A motor 4 is installed inside the placement frame 3. The lower end of the output shaft of the motor 4 is connected with a rotating rod 5. The rotating rod 5 is connected with a stirring paddle 6. The stirring paddle 6 is made of stainless steel. The stirring paddle 6 can break larger pieces of waste plastics into smaller pieces. An intercepting net 7 is connected inside the placement frame 3. The intercepting net 7 is located below the stirring paddle 6 and is used to intercept larger pieces of waste plastics. A fixing frame 8 is connected to the rotating rod 5. A plurality of blocking rods 9 are slidably connected to the fixing frame 8 at equal intervals to prevent larger pieces of waste plastics from blocking the intercepting net 7. An elastic member 10 is connected between the blocking rod 9 and the fixing frame 8. The lower end of the rotating rod 5 is connected with a connecting rod 11. A scraping plate 12 is connected to the connecting rod 11. One side of the scraping plate 12 close to the placement frame 3 is an inclined surface. The scraping plate 12 is used to scrape the debris remaining on the inner wall of the placement frame 3. A cylinder 13 is installed on the right side of the support frame 1. The left side of the telescopic end of the cylinder 13 is connected with a pressing plate 14. The pressing plate 14 is slidably matched with the rear side inside the hot-melting machine 2. The pressing plate 14 can push the hot-melted waste plastics to move until the hot-melted waste plastics are extruded. The upper left side of the support frame 1 is connected with a limiting plate 15. When placing the collection frame, the placement position of the collection frame can be limited to ensure that the extruded hot-melted waste plastics completely fall into the collection frame.

[0022] When the device is needed to carry out hot melting treatment on waste plastics, the staff place the waste plastics to be treated in the placement frame 3. During the placement of the waste plastics, the waste plastics may come into contact with the blocking rod 9 and exert pressure on the blocking rod 9, causing the blocking rod 9 to move downward along the fixing frame 8, and the elastic member 10 to be stretched. Once a certain amount of waste plastics accumulates inside the placement frame 3, the staff start the motor 4. The output shaft of the motor 4 drives the rotating rod 5 to rotate, and the rotating rod 5 drives the stirring paddle 6 to rotate. The stirring paddle 6 comes into contact with the waste plastics and breaks the larger pieces of waste plastics into smaller pieces, which is convenient for subsequent hot melting. During this process, the rotating rod 5 does not directly drive the fixing frame 8 and all the components thereon to rotate, because the function of the fixing frame 8 and the blocking rod 9 is to prevent larger pieces of waste plastics from blocking the interception net 7, rather than participating in the breaking process. Subsequently, the smaller pieces of waste plastics fall downward onto the interception net 7, and then continue to fall downward through the interception net 7 to the bottom inside the placement frame 3, and then fall from the bottom inside the placement frame 3 into the hot melting machine 2. Since the hot melting machine 2 is in a preheated state, it can immediately hot melt the smaller pieces of waste plastics. When the larger pieces of waste plastics fail to pass through the interception net 7, the larger pieces of waste plastics will stay on the interception net 7. During the continuous rotation of the stirring paddle 6, the intercepted larger pieces of waste plastics will come into contact with the stirring paddle 6 again, so that the larger pieces of waste plastics are broken into smaller pieces and then fall downward through the interception net 7 to the bottom inside the placement frame 3, and finally fall into the hot melting machine 2. At this time, the blocking rod 9 is no longer pressed, and under the reset action of the elastic member 10, the blocking rod 9 moves upward along the fixing frame 8 to the initial position. While the stirring paddle 6 breaks the waste plastics, the connecting rod 11 and the scraping plate 12 rotate with the rotating rod 5. The scraping plate 12 rotates and comes into contact with the inner wall of the placement frame 3, and scrapes the debris remaining on the inner wall of the placement frame 3 to ensure that all waste plastics can smoothly fall into the hot melting machine 2. Repeat the above operations. When a certain amount of smaller pieces of waste plastics is stored inside the hot melting machine 2, the motor 4 is turned off, and the hot melting machine 2 continues to hot melt these waste plastics into a molten state. After the hot melting is completed, the hot melting machine 2 is turned off, and then the collection frame is placed beside the limiting plate 15. Then the air cylinder 13 is started. The telescopic end of the air cylinder 13 drives the extrusion plate 14 to move leftward along the inside of the hot melting machine 2. The extrusion plate 14 moves and comes into contact with the hot-melted waste plastics, and pushes the hot-melted waste plastics to move leftward until the hot-melted waste plastics are extruded and fall into the collection frame, which is convenient for collecting the hot-melted waste plastics. When the hot-melted waste plastics inside the hot melting machine 2 are completely extruded, the telescopic end of the air cylinder 13 drives the extrusion plate 14 to move rightward along the inside of the hot melting machine 2 until the extrusion plate 14 moves back to the initial position, and then the air cylinder 13 is turned off.

[0023] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit the protection scope of the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the essence and scope of the technical solutions of the present invention.
