Description

Technical Field

[0001] This utility model relates to the field of thermal conductive gel production technology, specifically an extruder for producing organosilicon thermal conductive gel. Background Technology

[0002] Organosilicon thermal conductive gel is a high-performance thermal conductive material. It uses organosilicon polymer as a matrix and fills it with fillers such as ceramic powder and metal oxide with high thermal conductivity. It can easily fill uneven interfaces and meet the heat transfer requirements of various application scenarios. It exhibits high thermal conductivity, low compressibility, low pressure and high compression ratio, good electrical insulation and temperature resistance, and can be used in automated applications. It is widely used in electronic equipment, power appliances and other fields to solve the heat dissipation problem of heat-generating components and ensure the stable operation and service life of equipment.

[0003] After mass production of silicone thermal conductive gel, it needs to be repackaged and then extruded. Chinese utility model patent application CN202020668329.6 describes an extrusion device for the production and processing of thermal conductive gel. This device includes a motor and a push block. The motor rotates, causing the rotating block to rotate. A rotating rod on the rotating block is rotatably connected to a push rod. Therefore, when the rotating rod rotates, it drives the push rod, which in turn drives the push block to push the thermal conductive gel. The push block then extrudes the thermal conductive gel, making the operation more convenient and simple. However, the extrusion distance of the push block is consistent and cannot be adjusted. The amount of thermal conductive gel pushed out by the push block remains constant. Since different packaging requirements for silicone thermal conductive gel products often require different extrusion amounts, the inability to adjust the extrusion distance makes it difficult to adapt to different product requirements, significantly reducing the adaptability of the extruder. Utility Model Content

[0005] To achieve the above objectives, this utility model provides the following technical solution: an extruder for producing organosilicon thermal conductive gel, comprising a base, a housing slidably disposed on the surface of the base, an extruder head fixedly connected to the output end of the housing, a feeding hopper fixedly connected to the input end of the housing, a controller fixedly connected to the surface of the housing, a dispensing table fixedly connected to the surface of the base, a door rotatably disposed on the surface of the base, an extrusion mechanism disposed on the surface of the base, the extrusion mechanism comprising a servo motor, a rotating rod fixedly connected to the output shaft of the servo motor, a turntable fixedly connected to the surface of the rotating rod, a pushing block slidably connected to the surface of the housing, a rotating rod rotatably connected to the surface of the pushing block, an adjusting frame fixedly connected to the surface of the turntable, a first adjusting screw rotatably connected to the surface of the adjusting frame, a square nut threadedly connected to the surface of the first adjusting screw, an adjusting column fixedly connected to the surface of the square nut, the end of the rotating rod away from the pushing block rotatably connected to the surface of the adjusting column, and an adjusting knob fixedly connected to the top of the first adjusting screw.

An adjusting handwheel is fixedly connected to one end of the second adjusting screw. An adjusting connecting rod is rotatably connected to the surface of the moving block, and the end of the adjusting connecting rod away from the moving block is rotatably connected to the bottom of the chassis.

[0007] Preferably, the servo motor drives the rotating rod to rotate via the output shaft, and the rotating rod drives the turntable to rotate synchronously inside the chassis. The adjustment frame is located on one side of the center of the turntable, and the turntable drives the adjustment column to rotate synchronously via the adjustment frame.

[0008] Preferably, during the rotation of the turntable, one end of the rotating rod is driven to move and rotate via the adjusting column, and the rotating rod drives the pushing block to slide back and forth inside the chassis via rotation.

[0011] Preferably, during the sliding process, the moving block drives one end of the adjusting link to move and rotate, and the adjusting link pushes the chassis to slide horizontally and rise and fall on the surface of the base by rotation.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figure 1-5 One embodiment provided by this utility model: An extruder for producing silicone thermally conductive gel includes a base 1, a housing 11 slidably mounted on the surface of the base 1, an extruder head 12 fixedly connected to the output end of the housing 11, a feeding hopper 13 fixedly connected to the input end of the housing 11, a controller 14 fixedly connected to the surface of the housing 11, a dispensing table 15 fixedly connected to the surface of the base 1, and a door 16 rotatably mounted on the surface of the base 1. Dispensing boxes are placed on the dispensing table 15, and silicone thermally conductive gel enters through the feeding hopper 13. The housing 11 uses an extrusion mechanism to transport the silicone thermally conductive gel through the extruder head 12 into the dispensing box. An extrusion mechanism is mounted on the surface of the base 1, including a servo motor 2. A rotating rod 21 is fixedly connected to the output shaft of the servo motor 2, and a turntable 22 is fixedly connected to the surface of the rotating rod 21. A push block 23 is slidably connected to the surface of the housing 11, and a rotating... An adjusting frame 25 is fixedly connected to the surface of the rotating rod 24 and the turntable 22. A first adjusting screw 26 is rotatably connected to the surface of the adjusting frame 25. A square nut 27 is threadedly connected to the surface of the first adjusting screw 26. An adjusting column 29 is fixedly connected to the surface of the square nut 27. The end of the rotating rod 24 away from the push block 23 is rotatably connected to the surface of the adjusting column 29. An adjusting knob 28 is fixedly connected to the top of the first adjusting screw 26. When the extrusion mechanism is in use, the box door 16 needs to be opened. The extrusion mechanism can adjust the position of the adjusting column 29 on the turntable 22, thereby realizing the position of one end of the rotating rod 24 on the turntable 22. During the rotation of the turntable 22, by adjusting the position of the adjusting column 29, the distance that the rotating rod 24 transmits to the push block 23 to slide inside the machine box 11 is changed, thereby realizing the change of the extrusion amount of the push block 23 sliding in the machine box 11, and improving the adaptability of the extruder.

[0018] Furthermore, a lifting mechanism is provided on the surface of the base 1. The lifting mechanism includes a guide rod 3, which is fixedly connected to the surface of the base 1. A lifting block 31 is slidably connected to the surface of the guide rod 3. The lifting block 31 is fixedly connected to one side of the housing 11. A second adjusting screw 32 is rotatably connected to the surface of the base 1. A moving block 33 is threadedly connected to the surface of the second adjusting screw 32. An adjusting handwheel 34 is fixedly connected to one end of the second adjusting screw 32. An adjusting connecting rod 35 is rotatably connected to the surface of the moving block 33. The end of the adjusting connecting rod 35 away from the moving block 33 is rotatably connected to the bottom of the housing 11. The lifting mechanism can lift the housing 11 on the base 1, thereby changing the height of the extruder head 12, and thus changing the height distance between the extruder head 12 and the dispensing table 15. By adjusting the height distance, the extruder head 12 can be better matched with the dispensing box, avoiding problems such as splashing of thermal conductive gel or uneven filling caused by unsuitable height.

[0019] Furthermore, the servo motor 2 drives the rotating rod 21 to rotate through the output shaft. The rotating rod 21 drives the turntable 22 to rotate synchronously inside the housing 11. The adjustment frame 25 is located on one side of the center of the turntable 22. The turntable 22 drives the adjustment column 29 to rotate synchronously through the adjustment frame 25.

[0020] Furthermore, during the rotation of the turntable 22, one end of the rotating rod 24 is driven to move and rotate via the adjusting column 29, and the rotating rod 24 drives the push block 23 to slide back and forth inside the housing 11 through rotation. During the sliding process, the push block 23 extrudes the silicone thermal conductive gel inside the housing 11. The precise control of the servo motor 2 can ensure the stable rotation of the rotating rod 21 and the turntable 22, providing stable power for subsequent extrusion operations.

[0021] Furthermore, the first adjusting screw 26 is driven to rotate by the adjusting knob 28. The rotation of the first adjusting screw 26 drives the square nut 27 to slide on the surface of the adjusting frame 25. The square nut 27 drives the adjusting column 29 to slide synchronously, thereby realizing the adjustment of the position of the adjusting column 29 on the turntable 22, and thus realizing the adjustment of the position of the rotating rod 24 on the turntable 22. The operator can precisely change the position of the adjusting column 29 by rotating the adjusting knob 28 according to the actual production needs, thereby flexibly controlling the sliding distance and extrusion amount of the pushing block 23.

[0022] Furthermore, the chassis 11 moves horizontally up and down on the surface of the base 1 via the guide rod 3 and the lifting block 31. The second adjusting screw 32 is driven to rotate by the adjusting handwheel 34. The second adjusting screw 32 drives the moving block 33 to slide linearly on the surface of the base 1 by rotating. After the second adjusting screw 32 has rotated, its rotation is limited by friction. The second adjusting screw 32 also locks the position of the moving block 33 on the base 1 by the thread, ensuring the stability after adjustment.

[0023] Furthermore, during the sliding process, the moving block 33 drives one end of the adjusting rod 35 to move and rotate. The adjusting rod 35, through rotation, pushes the housing 11 to slide horizontally and rise and fall on the surface of the base 1, thereby adjusting the height of the housing 11 and changing the height distance between the extruder head 12 and the dispensing table 15. The rotational connection method of the adjusting rod 35 enables the linear motion of the moving block 33 to be smoothly converted into the lifting motion of the housing 11, ensuring the smoothness of the height adjustment.

[0024] Working principle: First, the silicone thermal conductive gel is added into the housing 11 through the feeding bucket 13. The servo motor 2 is started. The output shaft of the servo motor 2 drives the rotating rod 21 to rotate. The rotating rod 21 drives the turntable 22 to rotate synchronously. The adjusting frame 25 on the turntable 22 drives the adjusting column 29 to rotate. The adjusting column 29 drives one end of the rotating rod 24 to move and rotate. The rotating rod 24 then drives the pushing block 23 to slide back and forth inside the housing 11, extruding the silicone thermal conductive gel in the housing 11 through the extruder head 12 into the dispensing box on the dispensing table 15.

[0025] The operator can rotate the adjustment knob 28 to rotate the first adjustment screw 26. The rotation of the first adjustment screw 26 drives the square nut 27, which is threaded to it, to slide on the surface of the adjustment frame 25. The square nut 27 drives the adjustment column 29 to slide synchronously, thereby adjusting the position of the adjustment column 29 on the turntable 22. After the position of the adjustment column 29 changes, the position of one end of the rotating rod 24 on the turntable 22 also changes, which in turn changes the distance that the rotating rod 24 transmits to the push block 23 to slide inside the casing 11. Ultimately, this changes the extrusion volume of the push block 23 sliding in the casing 11, greatly improving the adaptability of the extruder and meeting the extrusion volume requirements of different products. The operator rotates the adjusting handwheel 34, driving the second adjusting screw 32 to rotate. The rotation of the second adjusting screw 32 causes the moving block 33, which is threaded to it, to slide linearly on the surface of the base 1. When the moving block 33 slides, it drives one end of the adjusting connecting rod 35 to move and rotate. The rotation of the adjusting connecting rod 35 pushes the machine box 11 to slide and rise horizontally on the surface of the base 1 through the guide rod 3 and the lifting block 31. After the height of the machine box 11 changes, the height of the extruder head 12, which is fixedly connected to its output end, also changes accordingly. This changes the height distance between the extruder head 12 and the dispensing table 15, achieving a good fit between the extruder head 12 and the dispensing box, and ensuring the stability of the dispensing process and product quality.

[0026] 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.
