Description

Technical Field

[0001] This utility model relates to the field of stirring device technology, and in particular to a rapid heating and melting stirring device for plastic raw materials. Background Technology

[0002] Plastic pipes are a general term for pipes made of plastic. They are favored by the pipeline engineering industry due to their lightweight, hygiene and safety, low water flow resistance, energy saving, metal saving, improved living environment, long service life, and safety and convenience. In the past decade, driven by my country's rapid economic development, my country's plastic pipe industry has experienced rapid growth against the backdrop of the booming chemical and building materials sectors. Plastic pipes have many advantages over traditional metal and concrete pipes in various fields, thus gaining widespread adoption. The production of plastic pipes involves various raw materials, which are mixed together, melted, and then thoroughly combined.

[0003] Chinese utility model patent CN221968544U discloses a novel raw material melting device for plastic pipe production. The device includes a fixed plate, a melting shell connected to the upper end of the fixed plate, a hopper connected to the lower end of the melting shell, a discharge pipe connected to the lower end of the hopper, a discharge valve installed on the outer wall of the discharge pipe, a feed inlet connected to the upper end of the melting shell, and a motor installed on the upper end of the melting shell, located to the right of the feed inlet. A stirring shaft is detachably connected to the output end of the motor. The lower end of the stirring shaft extends through and into the interior of the melting shell. Multiple stirring blades are fixedly connected to the outer wall of the stirring shaft. A filter plate is installed inside the melting shell, located between the hopper and the stirring shaft. This device facilitates the filtration and discharge of the molten raw material, preventing the discharge of incompletely molten particles and improving the quality of the plastic pipes after subsequent molding.

[0004] Regarding the aforementioned technologies, the inventors believe that the following defects exist: The aforementioned device drives the side scraper to rotate via a connecting rod connected to the stirring shaft, thereby cleaning the raw materials on the inner wall of the molten shell. In actual use, after a period of use, the side scraper is prone to wear, and gaps are easily generated between the side scraper and the inner wall of the molten shell, resulting in a poor cleaning effect and a poor user experience. Utility Model Content

[0005] To address the aforementioned problems, this invention provides a rapid heating and melting stirring device for plastic raw materials.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a plastic raw material rapid heating and melting stirring device, comprising a fixed plate, a support column installed on the bottom surface of the fixed plate, a melting shell installed on the fixed plate, a motor installed on the upper surface of the melting shell, a stirring rod connected to the output shaft of the motor, and a feed port provided on the melting shell. A filter plate is provided on the inner wall of the melting shell. Two telescopic rods are symmetrically installed on the stirring rod. A connecting rod is installed at the ends of the two telescopic rods. A sliding groove is provided on the side wall of the connecting rod. A sliding rod is slidably arranged in the sliding groove. A scraper is installed at the end of the sliding rod. A compression spring is fixed on the side wall of the sliding rod away from the scraper. The other end of the compression spring is fixed on the inner wall of the sliding groove.

[0007] By adopting the above technical solution, when workers need to produce plastic pipes, they need to inject plastic raw materials into the inlet and turn on the heating plate inside the molten shell to heat the raw materials. Then, the workers need to turn on the motor, causing the motor's output shaft to rotate, which in turn causes the stirring rod to rotate, thus stirring the raw materials. At this time, the telescopic rod and scraper rotate with the stirring rod, allowing the scraper to clean the inner wall of the molten shell, reducing the probability of raw materials adhering to the inner wall. During this process, the sliding rod is always under the elastic force of the compression spring, ensuring that the sliding rod and scraper are always pressed against the inner wall of the molten shell, reducing the probability of gaps between the inner wall and the scraper, thereby improving the cleaning effect of the scraper.

[0008] Furthermore, a movable groove is provided on the side wall of the connecting rod away from the scraper, a movable block is slidably disposed in the movable groove, a magnet is embedded on the side wall of the movable block near the scraper, and a magnet is fixed on the side wall of the sliding rod away from the scraper, and the magnet and the magnet attract each other.

[0009] By adopting the above technical solution, when the worker does not need to use the scraper, the worker only needs to slide the moving block to make the magnetic block and the magnetic rod face each other, so that the magnetic block and the magnetic rod attract each other, thereby causing the scraper to separate from the inner wall of the molten shell under the action of the magnetic block.

[0010] Furthermore, the telescopic rod includes a sleeve fixed to the stirring rod, a sleeve rod slidably connected to the sleeve, and a fixing device provided on the sleeve for fixing the sleeve rod.

[0011] Furthermore, one of the telescopic rods has a through-hole, and the other telescopic rod has a threaded hole. The fixing device includes a fixing rod that is slidably disposed in the connecting hole and a threaded rod that is fixed to the bottom surface of the fixing rod. The threaded rod is threadedly connected to the threaded hole.

[0012] By adopting the above technical solution, after a period of use, the scraper is prone to wear and tear, requiring replacement by the operator. At this time, the operator needs to rotate the threaded rod to separate it from the threaded hole. Then, the operator needs to pull the fixing rod upwards to separate it from the connecting hole. Further, the operator needs to slide the sleeve rod to move the scraper closer to the mixing rod, thus moving the scraper directly below the feed inlet.

[0013] Furthermore, a T-shaped rod is slidably provided on the upper surface of the sliding rod, and the T-shaped rod is fixed to the scraper.

[0014] Furthermore, the upper surface of the T-shaped rod is flush with the upper surface of the scraper.

[0015] By adopting the above technical solution, when the scraper moves to directly below the feed inlet, the operator only needs to pull the scraper upward to separate the T-shaped rod from the sliding rod, thereby separating the scraper from the sliding rod and reducing the difficulty of the operator replacing the scraper.

[0016] Furthermore, the upper surface of the sliding rod is rotatably provided with a stop for blocking the T-shaped rod.

[0017] By adopting the above technical solution, when the operator connects the T-shaped rod and the sliding rod, the operator only needs to rotate the stop block to block the T-shaped rod, thereby improving the stability of the T-shaped rod and thus improving the operator's user experience.

[0018] Furthermore, the upper end of the fixing rod is provided with a handle to reduce the difficulty for workers to rotate the fixing rod.

[0019] In summary, this utility model has the following beneficial effects:

[0020] 1. In this application, when workers need to produce plastic pipes, they need to inject plastic raw materials into the inlet and turn on the heating plate inside the molten shell to heat the raw materials. Further, workers need to turn on the motor, causing the motor's output shaft to rotate, which in turn causes the stirring rod to rotate, thus stirring the raw materials. At this time, the telescopic rod and scraper rotate with the stirring rod, allowing the scraper to clean the inner wall of the molten shell, thereby reducing the probability of raw materials adhering to the inner wall. During this process, the sliding rod is always subjected to the elastic force of the compression spring, ensuring that the sliding rod and scraper are always pressed against the inner wall of the molten shell, thus reducing the probability of gaps between the inner wall of the molten shell and the scraper, thereby improving the cleaning effect of the scraper.

[0021] 2. In this application, when the worker does not need to use the scraper, the worker only needs to slide the moving block to make the magnetic block and the magnetic rod face each other, so that the magnetic block and the magnetic rod attract each other, thereby causing the scraper to separate from the inner wall of the molten shell under the action of the magnetic block;

[0022] 3. In this application, after a period of use, the scraper is prone to wear and tear, requiring replacement by the operator. To do this, the operator needs to rotate the threaded rod to separate it from the threaded hole. Then, the operator needs to pull the fixing rod upwards to separate it from the connecting hole. Further, the operator needs to slide the sleeve rod to move the scraper closer to the mixing rod, thus moving it directly below the feed inlet. Attached Figure Description

[0031] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0032] like Figure 1-7 As shown in the embodiment of this application, a plastic raw material rapid melting and stirring device is disclosed, including a fixed plate 1, a support column 11, a melting shell 2, a motor 21, a stirring rod 3, a feed inlet 31, a telescopic rod 4, a connecting rod 5, a sliding rod 6, a scraper 61, a compression spring 7, a moving block 72, a magnet block 8, a magnet rod 81, a T-shaped rod 82, and a stop block 83. The support column 11 is a round rod structure and is installed on the bottom surface of the fixed plate 1. The melting shell 2 is installed on the fixed plate 1, and the motor 21 is installed on the upper surface of the melting shell 2. The stirring rod 3 is connected to the output shaft of the motor 21, and the feed inlet 31 is provided on the melting shell 2. The filter plate 32 is provided on the inner wall of the melting shell 2 for filtering the raw material. The connecting rod 5 is a rectangular rod structure and is installed at the ends of two telescopic rods 4. A sliding groove 51 is provided on the side wall of the connecting rod 5, and the sliding rod 6 is a rectangular rod structure that is slidably disposed in the sliding groove 51. The scraper 61 is installed at the end of the sliding rod 6, one end of the compression spring 7 is fixed on the side wall of the sliding rod 6 away from the scraper 61, and the other end of the compression spring 7 is fixed on the inner wall of the sliding groove 51.

[0033] Two telescopic rods 4 are symmetrically mounted on the stirring rod 3. The telescopic rod 4 includes a sleeve 41, a rod 42, and a fixing device 43. The sleeve 41 is a rod-shaped structure with one end open and is fixed to the stirring rod 3. The rod 42 is a rectangular rod-shaped structure and is slidably connected to the sleeve 41.

[0034] One telescopic rod 4 has a through-hole 421, and the other telescopic rod 4 has a threaded hole 422. A fixing device 43 is mounted on the sleeve 41 to fix the sleeve rod 42. The fixing device 43 includes a fixing rod 431 and a threaded rod 432. The fixing rod 431 is a rectangular rod structure and is slidably disposed within the through-hole 421. The threaded rod 432 is fixed to the bottom surface of the fixing rod 431 and is threadedly connected to the threaded hole 422.

[0035] After a period of use, scraper 61 is prone to wear and tear, requiring replacement. To do this, rotate threaded rod 432 to separate it from threaded hole 422. Then, pull fixed rod 431 upwards to separate it from connecting hole 421. Further, slide sleeve rod 42 to move scraper 61 closer to stirring rod 3, ultimately positioning it directly below feed inlet 31.

[0036] A moving groove 71 is formed on the side wall of the connecting rod 5 away from the scraper 61. The moving block 72 is a block structure and is slidably disposed in the moving groove 71. The magnet block 8 is a block structure and is embedded in the side wall of the moving block 72 near the scraper 61. The magnet rod 81 is a rod structure and is fixed to the side wall of the sliding rod 6 away from the scraper 61, and the magnet block 8 and the magnet rod 81 are attracted to each other.

[0037] When the worker does not need to use the scraper 61, the worker only needs to slide the moving block 72 to make the magnet block 8 and the magnet rod 81 face each other, so that the magnet block 8 and the magnet rod 81 attract each other, thereby causing the scraper 61 to separate from the inner wall of the molten shell 2 under the action of the magnet block 8.

[0038] The T-shaped rod 82 is a rod-shaped structure with a T-shaped cross-section. The T-shaped rod 82 is slidably disposed on the upper surface of the sliding rod 6. The T-shaped rod 82 is fixed to the scraper 61, and the upper surface of the T-shaped rod 82 is flush with the upper surface of the scraper 61.

[0039] When the scraper 61 moves to directly below the feed inlet 31, the operator only needs to pull the scraper 61 upwards to separate the T-shaped rod 82 from the sliding rod 6, thereby separating the scraper 61 from the sliding rod 6 and reducing the difficulty of the operator replacing the scraper 61.

[0040] The stop block 83 is a block-shaped structure that is rotatably mounted on the upper surface of the sliding rod 6 to block the T-shaped rod 82. When the operator connects the T-shaped rod 82 to the sliding rod 6, the operator only needs to rotate the stop block 83 to block the T-shaped rod 82, thereby improving the stability of the T-shaped rod 82 and thus improving the operator's user experience.

[0041] To reduce the difficulty for workers to rotate the fixed rod 431, a handle 9 is provided at the upper end of the fixed rod 431.

[0042] The operating principle of the rapid melting and stirring device for plastic raw materials in this embodiment is as follows: When workers need to produce plastic pipes, they need to inject plastic raw materials into the feed inlet 31 and turn on the heating plate inside the molten shell 2, which heats the raw materials inside the molten shell 2. Further, workers need to turn on the motor 21, causing the output shaft of the motor 21 to rotate, thereby causing the stirring rod 3 to rotate with the output shaft of the motor 21, thus stirring the raw materials. At this time, the telescopic rod 4 and the scraper 61 rotate with the stirring rod 3, thereby cleaning the inner wall of the molten shell 2 with the scraper 61, reducing the probability of raw materials adhering to the inner wall of the molten shell 2. During this process, the sliding rod 6 is always subjected to the elastic force of the compression spring 7, thus keeping the sliding rod 6 and the scraper 61 pressed tightly against the inner wall of the molten shell 2, reducing the probability of gaps between the inner wall of the molten shell 2 and the scraper 61, thereby improving the cleaning effect of the scraper 61.

[0043] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
