Abstract
Description
Technical Field
[0001] This utility model relates to the field of raw material processing and batching technology, and in particular to a thermoplastic elastomer raw material processing device. Background Technology
[0002] Thermoplastic elastomer (TPE) processing technology has been widely used in the plastics industry. Its superior flexibility, abrasion resistance, and weather resistance make it an ideal choice for many industries. With increasing emphasis on environmental protection and sustainable development, the application scope of TPE continues to expand, covering multiple fields such as automotive, electronics, medical, and daily necessities. Advanced processing technologies such as injection molding, extrusion, and blow molding enable TPE to meet the needs of different products in various forms. With the advancement of materials science, the performance of TPE has also been continuously optimized, leading to the development of a variety of new composite materials that improve its mechanical and processing properties.
[0003] Existing thermoplastic elastomer raw material batching equipment still has significant shortcomings in actual use. Typically, these devices require weighing the mass of each raw material sequentially according to the raw material ratio. This process is not only cumbersome but also leads to low weighing efficiency. Each weighing operation requires separate operation, consuming a lot of time and causing production line stagnation, which in turn reduces the overall batching efficiency. The low batching efficiency directly affects output, making it difficult for companies to maintain an advantage in a highly competitive market. Frequent manual operation increases the probability of errors, which may lead to material waste and further increase production costs, failing to meet actual needs. Utility Model Content
[0004] This utility model discloses a thermoplastic elastomer raw material processing device, which aims to solve the technical problems mentioned in the technical problem.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A thermoplastic elastomer raw material processing device includes a machine body, a mounting shell fixedly connected to the upper surface of the machine body, a fixed plate fixedly connected to the top of the mounting shell, a plurality of circular openings provided on the upper surface of the fixed plate, a storage cylinder provided at the bottom of the circular openings, a first solenoid valve provided at the bottom of the storage cylinder, a weighing mechanism installed on one side of the storage cylinder, a mounting frame fixedly connected to the top of the fixed plate, a plurality of suction mechanisms installed on the upper surface of the mounting frame, and a touch screen fixedly connected to the upper surface of the machine body near the mounting shell, with a controller installed inside the touch screen.
[0007] The weighing mechanism includes sliders fixedly connected to both sides of the storage cylinder, a slide rail slidably connected to one side of the slider, the top of the slide rail being fixedly connected to the bottom of the fixed plate, and a weighing device being provided on one side of the slide rail.
[0008] The weighing device is equipped with a pressure sensor inside, and a contact rod is slidably connected to the top of the weighing device. The slider squeezes the contact rod, thereby squeezing the pressure sensor at the bottom of the weighing device.
[0009] In a preferred embodiment, the suction mechanism includes multiple suction cylinders fixedly connected to the upper surface of the mounting frame. A suction motor is fixedly connected to the top of the suction cylinder, and a receiving cylinder is fixedly connected to one end of the output shaft of the suction motor. The top of the receiving cylinder is provided with multiple air outlets and multiple feed inlets. The internal space of the receiving cylinder is divided into four independent spaces, and the bottom of the receiving cylinder is not closed.
[0010] The suction mechanism also includes a base plate fixedly connected to the inner wall of the bottom of the suction cylinder. The base plate contacts the bottom of the receiving cylinder. During the rotation of the receiving cylinder, the base plate seals the bottom of the receiving cylinder within a 90-degree range centered on the output shaft of the suction motor. The bottom of the receiving cylinder is left open at 270 degrees. A selection motor is fixedly connected to the bottom of the base plate, and a rotating tube is fixedly connected to one end of the output shaft of the selection motor.
[0011] A negative pressure box is fixedly connected to the top inner wall of the suction cylinder. Multiple negative pressure holes are provided on the lower surface of the negative pressure box. An air outlet pipe is inserted into one side of the negative pressure box and connected to an air pump. A second solenoid valve is provided at one end of the air outlet pipe. A metal tube is inserted into the top of the suction cylinder near the suction motor.
[0012] Multiple feed pipes are inserted into the top of the metal tube, and the feed pipes are connected to the feed box. The bottom of the metal tube is aligned with the feed inlet, and a third solenoid valve is installed at one end of the feed pipe.
[0013] As can be seen from the above, the thermoplastic elastomer raw material processing device provided by this utility model has the following technical effects.
[0014] Firstly, when raw material proportioning is required, a slider slides on one side of a slide rail. The slider, the storage cylinder, and the raw materials inside the storage cylinder press against a contact rod. The contact rod presses against a pressure sensor, weighing the raw materials inside the storage cylinder. Based on the proportion of raw materials, the controller controls the first solenoid valve at the bottom of different storage cylinders to release a proportional amount of raw materials. Different raw materials fall to the bottom of the mounting shell, activating the stirring motor to drive the stirring wheel to rotate, thoroughly mixing the raw materials. Finally, the electric valve is activated to pour out the mixed raw materials, greatly improving the efficiency of thermoplastic elastomer raw material proportioning.
[0015] Secondly, the raw materials are drawn into an independent space inside the receiving cylinder by negative pressure. The receiving cylinder rotates 90 degrees, causing the raw materials in the independent space to fall into the interior of the rotating tube. The bottom of the rotating tube stops directly above one of the storage cylinders, and the raw materials fall into the storage cylinder for temporary storage. By controlling the third solenoid valve on different feed pipes, raw materials of different colors can enter different storage cylinders through different feed pipes, thus achieving the effect of storing multiple colors of raw materials at the same time.

[0025] The weighing mechanism includes sliders 12 fixedly connected to both sides of the storage cylinder 10. A slide rail 14 is slidably connected to one side of the slider 12. The top of the slide rail 14 is fixedly connected to the bottom of the fixed plate 3. A weighing device 11 is provided on one side of the slide rail 14.
[0026] The weighing device 11 is equipped with a pressure sensor inside. A contact rod is slidably connected to the top of the weighing device 11. The slider 12 presses the contact rod, thereby pressing the pressure sensor at the bottom of the weighing device 11.
[0027] In this embodiment, when raw material proportioning is required, the slider 12 slides on one side of the slide rail 14. The slider 12, the storage cylinder 10, and the raw materials inside the storage cylinder 10 press against the contact rod. The contact rod presses against the pressure sensor to weigh the raw materials inside the storage cylinder 10. According to the proportion of raw materials, the controller controls the first solenoid valve at the bottom of different storage cylinders 10 to release a proportional amount of raw materials. Different raw materials fall to the bottom of the mounting shell 2. The stirring motor 9 is started to drive the stirring wheel 8 to rotate, and the raw materials are fully stirred. The electric valve 7 is started to pour out the mixed raw materials, which greatly improves the efficiency of thermoplastic elastomer raw material proportioning.
[0028] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4In a preferred embodiment, the suction mechanism includes a plurality of suction cylinders 5 fixedly connected to the upper surface of the mounting frame 4. A suction motor 17 is fixedly connected to the top of the suction cylinder 5. A receiving cylinder 13 is fixedly connected to one end of the output shaft of the suction motor 17. A plurality of air outlets 15 and a plurality of feed inlets 16 are provided on the top of the receiving cylinder 13. The internal space of the receiving cylinder 13 is divided into four independent spaces on an equal basis. The bottom of the receiving cylinder 13 is not closed.
[0029] The suction mechanism also includes a base plate 23 fixedly connected to the inner wall of the bottom of the suction cylinder 5. The base plate 23 contacts the bottom of the receiving cylinder 13. During the rotation of the receiving cylinder 13, the base plate 23 seals the bottom of the receiving cylinder 13 within a 90-degree range centered on the output shaft of the suction motor 17. The bottom of the receiving cylinder 13 is left open by 270 degrees. A selection motor 22 is fixedly connected to the bottom of the base plate 23. A rotating tube 21 is fixedly connected to one end of the output shaft of the selection motor 22.
[0030] A negative pressure box 24 is fixedly connected to the inner wall of the top of the suction cylinder 5. Multiple negative pressure holes 25 are provided on the lower surface of the negative pressure box 24. An air outlet pipe 20 is inserted into one side of the negative pressure box 24. The air outlet pipe 20 is connected to an air pump. A second solenoid valve is provided at one end of the air outlet pipe 20. A metal tube 19 is inserted into the top of the suction cylinder 5 near the suction motor 17.
[0031] Multiple feed pipes 18 are inserted into the top of the metal tube 19. The feed pipes 18 are connected to the feed box. The bottom of the metal tube 19 is aligned with the position of the feed port 16. A third solenoid valve is provided at one end of the feed pipe 18.
[0032] It needs to be explained that the feed pipe 18 is connected to the feed box, and thermoplastic elastomer raw materials are put into the feed box. The air outlet pipe 20 is connected to the air pump, and the air pump is used to draw air out through the air outlet pipe 20, generating negative pressure inside the negative pressure box 24. Since the feed port 16 at the top of the receiving cylinder 13 is connected to the metal pipe 19, the bottom of the receiving cylinder 13 is sealed by the bottom plate 23.
[0033] In this embodiment, negative pressure draws raw materials from the feed box into an independent space inside the receiving cylinder 13 through the metal pipe 19 and the feed pipe 18. The suction motor 17 is started to drive the receiving cylinder 13 to rotate 90 degrees, causing the raw materials drawn into the independent space inside the receiving cylinder 13 to fall into the rotating tube 21. The selector motor 22 is controlled to drive the rotating tube 21 to rotate, so that the bottom end of the rotating tube 21 stops directly above one of the storage cylinders 10. The raw materials fall into the storage cylinder 10 and are temporarily stored. By controlling the third solenoid valve on different feed pipes 18, raw materials of different colors can enter different storage cylinders 10 through different feed pipes 18, achieving the effect of storing multiple colors of raw materials at the same time. The same raw materials can also be stored in multiple storage cylinders 10 at the bottom of different suction mechanisms.
[0034] Working principle: During use, the feed pipe 18 is connected to the feed box, and thermoplastic elastomer raw materials are fed into the feed box. The air outlet pipe 20 is connected to the air pump, and the air pump draws air out through the air outlet pipe 20, generating negative pressure inside the negative pressure box 24. Since the feed port 16 at the top of the receiving cylinder 13 is connected to the metal pipe 19, and the bottom of the receiving cylinder 13 is sealed by the bottom plate 23, the negative pressure draws the raw materials in the feed box into an independent space inside the receiving cylinder 13 through the metal pipe 19 and the feed pipe 18. The suction motor 17 is started to drive the receiving cylinder 13 to rotate 90 degrees, causing the raw materials drawn into the independent space inside the receiving cylinder 13 to fall into the rotating tube 21. The control selector motor 22 drives the rotating tube 21 to rotate, so that the bottom end of the rotating tube 21 stops directly above one of the storage cylinders 10, and the raw materials fall into the storage cylinder 10 for temporary storage. The third solenoid valve on different feed pipes 18 is controlled. This allows raw materials of different colors to enter different storage cylinders 10 through different feed pipes 18, achieving the effect of storing multiple colors of raw materials simultaneously. It also allows the same raw materials to be stored in multiple storage cylinders 10 at the bottom of different feeding mechanisms. When raw material proportioning is required, the slider 12 slides on one side of the slide rail 14. The slider 12, the storage cylinder 10, and the raw materials inside the storage cylinder 10 press against the contact rod. The contact rod presses against the pressure sensor, weighing the raw materials inside the storage cylinder 10. According to the raw material proportioning ratio, the controller controls the first solenoid valve at the bottom of different storage cylinders 10 to release a proportional amount of raw materials. Different raw materials fall to the bottom of the mounting shell 2, and the stirring motor 9 is started to drive the stirring wheel 8 to rotate, thoroughly mixing the raw materials. The electric valve 7 is then activated to pour out the mixed raw materials, greatly improving the efficiency of thermoplastic elastomer raw material proportioning.

The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the protection scope of this utility model.
