Description

Technical Field

[0001] This utility model relates to the field of raw material addition technology for the production of heat-dissipating plastic particle materials, and in particular to a raw material addition device for the production of heat-dissipating plastic particle materials. Background Technology

[0002] Due to its excellent thermal conductivity and broad application prospects, heat-dissipating plastic particles have become an indispensable material in modern industry. With the advancement of technology, the production process of heat-dissipating plastic particles has been constantly evolving, and the raw material addition technology has also developed accordingly. This technology involves the precise proportioning and mixing of various particles to ensure that the final product has good thermal conductivity and mechanical properties. In order to meet the market demand for high-performance heat dissipation materials, manufacturers are gradually introducing automated control systems and intelligent proportioning equipment to improve the accuracy and efficiency of raw material addition.

[0003] In the production process of heat-dissipating plastic particle materials, traditional raw material addition devices usually adopt the method of directly conveying and mixing multiple raw material particles, lacking the process of weighing and precise proportioning. This operation method makes it impossible to effectively control the quality of raw materials, resulting in inaccurate proportions, which in turn affects the performance and quality of the final product. If the ratio of heat-dissipating filler to matrix material in the heat-dissipating plastic particles is inappropriate, it may lead to substandard thermal conductivity of the material, and even affect the stability and durability of the finished product. The randomness of raw material addition may also lead to waste of raw materials in the production process, increase production costs, and fail to meet actual needs. Utility Model Content

[0004] This utility model discloses a raw material addition device for the production of heat-dissipating plastic particle materials. The aim is to solve the technical problems arising from the fact that traditional raw material addition devices typically use direct mixing of multiple raw material particles during the production process of heat-dissipating plastic particle materials, lacking a weighing and precise proportioning process. This operation method leads to ineffective control of raw material quality, resulting in inaccurate proportions, which in turn affects the performance and quality of the final product. Furthermore, improper ratios of heat-dissipating filler to matrix material in the heat-dissipating plastic particles may lead to substandard thermal conductivity, even affecting the stability and durability of the finished product. The arbitrary addition of raw materials can also lead to material waste during production, increasing production costs.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A raw material addition device for producing heat-dissipating plastic particle materials includes a base plate. Multiple raw material bins are fixedly connected to the upper surface of the base plate. A conveyor motor is fixedly connected to one side of the bottom of each raw material bin. A conveyor threaded rod is provided at one end of the output shaft of the conveyor motor, and a guide pipe is provided outside the conveyor threaded rod. A mixing disc is positioned on the upper surface of the base plate between the multiple raw material bins. A weighing disc is positioned on top of the mixing disc. Multiple mounting cylinders are fixedly connected inside the weighing disc. Multiple ball bearing guides are provided inside the mounting cylinders. A weighing cylinder is fixedly connected to one side of each ball bearing guide. A guide rod is slidably connected to one side of the weighing cylinder. An extrusion rod is fixedly connected to the bottom of one side of the weighing cylinder. A pressure sensor is provided at the bottom of the extrusion rod. A switching motor is positioned on the other side of the weighing cylinder. A switching threaded rod is fixedly connected to one end of the output shaft of the switching motor. A moving block is threadedly connected to one end of the switching threaded rod. A switching disk is rotatably connected to the bottom of the weighing cylinder. A sliding groove is provided at one end of the switching disk, and sliding rods are provided on both sides of the moving block.

[0007] The ball bearing guide is used to reduce the friction of the weighing cylinder sliding up and down, making the detection data of the pressure sensor more accurate.

[0008] In a preferred embodiment, a rod is fixedly connected to the top inner wall of the raw material box, a lifting frame is slidably connected to one end of the rod, a warning bar is fixedly connected to the top of the lifting frame, a warning ball is provided at the top of the warning bar, and a spring is sleeved at the bottom end of the rod.

[0009] The raw material box is rotatably connected to a feed door on one side. A handle is provided on the outer wall of the feed door, and the warning ball is red.

[0010] As can be seen from the above, the raw material addition equipment for the production of heat-dissipating plastic particle materials provided by this utility model has the following technical effects.

[0011] Firstly, the weight of the raw material particles causes the weighing cylinder to slide downwards, which in turn drives the extrusion rod to press against the pressure sensor at the bottom of the extrusion rod. The pressure sensor detects the mass of the raw material particles entering the weighing cylinder. When the mass reaches the required weight in the formula, the conveyor motor stops rotating, and at the same time, the switch motor is activated to drive the switch threaded rod to rotate, causing the moving block to slide downwards and drive the switch plate to rotate. This causes the raw material particles inside the weighing cylinder to fall into the mixing plate. Multiple raw materials are weighed using multiple weighing cylinders and pressure sensors, which makes the ratio of raw materials more accurate, thus achieving the effect of making the ratio of multiple raw materials in thermoplastic particle materials more precise.

[0012] Secondly, initially, the raw material particles inside the raw material box compress the lifting frame, causing the lifting frame to slide downwards after compressing the spring. As the raw material particles inside the raw material box are continuously consumed, the raw material particles accumulated on the lifting frame gradually decrease. Under the action of the spring force, the lifting frame gradually rises, causing the warning bar to slide upwards. Workers can observe the position change of the warning bar through the observation window, thus knowing that the raw material is decreasing. They can then open the feeding door to add raw material. Insufficient raw material leads to inaccurate thermoplastic particle raw material ratios, thus preventing errors in the thermoplastic particle raw material ratios. Attached Figure Description

[0021] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 A raw material addition device for producing heat-dissipating plastic particle materials includes a base plate 1. Multiple raw material bins 3 are fixedly connected to the upper surface of the base plate 1. A conveyor motor 7 is fixedly connected to one side of the bottom of each raw material bin 3. A conveyor threaded rod 6 is provided at one end of the output shaft of the conveyor motor 7. A guide pipe 4 is provided outside the conveyor threaded rod 6. A mixing disc 2 is positioned on the upper surface of the base plate 1 between the multiple raw material bins 3. A weighing disc 5 is positioned on top of the mixing disc 2. Multiple mounting cylinders 14 are fixedly connected inside the weighing disc 5. Multiple ball bearing guides are provided inside the mounting cylinders 14. One side of each ball bearing guide is fixedly connected to... A weighing cylinder 15 is connected to the weighing cylinder 15. A guide rod 16 is slidably connected to one side of the weighing cylinder 15. A pressing rod 17 is fixedly connected to the bottom of one side of the weighing cylinder 15. A pressure sensor 18 is installed at the bottom of the pressing rod 17. A switch motor 23 is installed on the other side of the weighing cylinder 15. A switch threaded rod 22 is fixedly connected to one end of the output shaft of the switch motor 23. A moving block 21 is threadedly connected to one end of the switch threaded rod 22. A switch disk 19 is rotatably connected to the bottom of the weighing cylinder 15. A slide groove 20 is provided at one end of the switch disk 19. Slide rods are provided on both sides of the moving block 21. The slide rods slide inside the slide groove 20.

[0022] Among them, the ball bearing guide rail is used to reduce the friction of the weighing cylinder 15 sliding up and down, so that the detection data of the pressure sensor 18 is more accurate, and the bottom end of the guide rod 16 is fixedly connected to the bottom inner wall of the weighing pan 5.

[0023] In this embodiment, the heat-dissipating plastic particle material requires the mixing of multiple raw materials. Each raw material is placed in a different raw material box 3. The conveying motor 7 is started to drive the conveying threaded rod 6 to rotate, continuously conveying the raw material particles inside the raw material box 3 to one end of the guide tube 4. One end of the guide tube 4 is located directly above the weighing pan 5. The raw material is discharged from one end of the guide tube 4 and falls into the corresponding weighing cylinder 15.

[0024] Furthermore, the weight of the raw material particles causes the weighing cylinder 15 to slide downwards, which in turn causes the extrusion rod 17 to press the pressure sensor 18 at the bottom of the extrusion rod 17. The pressure sensor 18 detects the mass of the raw material particles entering the weighing cylinder 15. When the mass reaches the required weight of the formula, the controller controls the transmission motor 7 to stop rotating. At the same time, the switch motor 23 is started to drive the switch threaded rod 22 to rotate, causing the moving block 21 to slide downwards and drive the switch disk 19 to rotate. This causes the raw material particles inside the weighing cylinder 15 to fall into the mixing disk 2. Multiple raw materials are weighed using multiple weighing cylinders 15 and pressure sensors 18, which makes the ratio of raw materials more accurate and achieves the effect of making the ratio of multiple raw materials of thermoplastic particle materials more accurate.

[0025] Reference Figure 1 , Figure 3 and Figure 4 In a preferred embodiment, a rod 10 is fixedly connected to the top inner wall of the raw material box 3, a lifting frame 13 is slidably connected to one end of the rod 10, a warning rod 9 is fixedly connected to the top of the lifting frame 13, a warning ball 11 is provided on the top of the warning rod 9, and a spring 12 is sleeved on the bottom end of the rod 10.

[0026] Specifically, a feed door 8 is rotatably connected to one side of the raw material box 3. A handle is provided on the outer wall of the feed door 8. The warning ball 11 is red. Observation windows are provided on both sides of the raw material box 3.

[0027] In this embodiment, initially, the raw material particles inside the raw material box 3 compress the lifting frame 13, thereby causing the lifting frame 13 to compress the spring 12 and slide downward. As the raw material particles inside the raw material box 3 are continuously consumed, the raw material particles accumulated on the lifting frame 13 gradually decrease. Under the action of the elastic force of the spring 12, the lifting frame 13 gradually rises, thereby causing the warning bar 9 to slide upward. The worker observes the position change of the warning bar 9 through the observation window, thereby knowing that the raw material is reduced, and opens the feeding door 8 to add raw material. Insufficient raw material leads to inaccurate thermoplastic particle raw material ratio, which plays a role in preventing errors in the thermoplastic particle raw material ratio.

[0028] Working Principle: During use, the heat-dissipating plastic particle material requires a mixture of various raw materials. Each raw material is placed in a separate raw material bin 3. The conveyor motor 7 is started, driving the conveyor threaded rod 6 to rotate, continuously conveying the raw material particles from the raw material bin 3 to one end of the guide pipe 4. One end of the guide pipe 4 is directly above the weighing pan 5. The raw material exits from one end of the guide pipe 4 and falls into the corresponding weighing cylinder 15. Due to the weight of the raw material particles, the weighing cylinder 15 slides downwards, causing the extrusion rod 17 to press against the pressure sensor 18 at the bottom of the extrusion rod 17. The pressure sensor 18 detects the mass of the raw material particles entering the weighing cylinder 15. When the mass reaches the required weight in the formula, the controller stops the conveyor motor 7 and simultaneously starts the switch motor 23, driving the switch threaded rod 22 to rotate, causing the moving block 21 to slide downwards, which in turn causes the switch disc 19 to rotate. The raw material particles inside the weighing cylinder 15 fall into the mixing tray 2. Multiple raw materials are weighed using multiple weighing cylinders 15 and pressure sensors 18, thereby making the raw material ratio more accurate. This achieves the effect of making the ratio of multiple raw materials in thermoplastic particle material more precise. Initially, the raw material particles inside the raw material box 3 squeeze the lifting frame 13, which in turn drives the lifting frame 13 to squeeze the spring 12 and slide downward. As the raw material particles inside the raw material box 3 are continuously consumed, the raw material particles accumulated on the lifting frame 13 gradually decrease. Under the action of the elastic force of the spring 12, the lifting frame 13 gradually rises, thereby driving the warning bar 9 to slide upward. The worker observes the position change of the warning bar 9 through the observation window, thereby knowing that the raw material is reduced. The feed door 8 is opened to add raw material. Insufficient raw material leads to inaccurate thermoplastic particle raw material ratio, which has the effect of preventing errors in the thermoplastic particle raw material ratio.
