Abstract
Description
Technical Field
[0001] This utility model relates to the field of silicone strip production technology, specifically a silicone strip extrusion device. Background Technology
[0002] Conductive silicone rubber is a special material in which conductive particles are uniformly distributed within silicone rubber through a special process. Pressure is applied to bring these particles into contact, resulting in excellent conductivity and thus enabling it to perform its function. Conductive silicone rubber possesses good mechanical properties and electromagnetic shielding performance, and has applications in both military and commercial fields. It is an ideal product that can simultaneously provide environmental sealing and electromagnetic shielding.
[0003] Chinese patented invention CN212829945U discloses a silicone strip extrusion device, which includes a machine body. A collection bucket is provided at the discharge end of the machine body. The top of the collection bucket is open. A central shaft is arranged along the axial length of the collection bucket inside the collection bucket. Multiple partitions are circumferentially spaced on the sidewall of the central shaft. The side of each partition away from the central shaft abuts against the inner wall of the collection bucket. This application has the effect of preventing multiple silicone strips from tangling.
[0004] However, the device still has some problems. In actual use, when the extrusion die is fixed, it cannot be replaced, making it difficult to produce various types of silicone strips. Even if the extrusion die in some devices can be replaced, they are generally fastened with bolts or flanges, requiring special tools for disassembly. Moreover, the die positioning needs to be repeatedly adjusted, which is extremely inconvenient. Therefore, we propose a silicone strip extrusion device to solve the above problems.

[0015] (III) Beneficial Effects
[0016] Compared with the prior art, the present invention provides a silicone strip extrusion device, which has the following advantages:
[0017] This invention utilizes a movable ring, which, via a hinged rod, drives a corresponding connecting block to slide on a T-shaped rod. During this movement, the connecting block compresses a corresponding first spring, simultaneously causing a corresponding locking pin to separate from its slot. Next, the extrusion die is moved and removed. Then, a mounting block on another extrusion die is inserted into its mounting groove. When one side of the extrusion die contacts the end of the connecting tube, the force on the movable ring is released, causing the first spring, which was under compression, to return to its original position. Under the action of its own elastic force, the first spring drives the connecting block to move, causing the locking pin to engage with the corresponding slot, thus fixing the other extrusion die. This allows for die replacement without the need for specialized tools and enables the production of silicone strips of different specifications. Attached Figure Description

[0024] 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.
[0025] Example
[0026] like Figure 1-5As shown, an embodiment of this utility model discloses a silicone strip extrusion device, including a workbench 1. A device body 2 is fixedly connected to the top of the workbench 1. A connecting pipe 3 is connected and fixed to one side of the device body 2. T-shaped rods 4 are welded to both sides of the connecting pipe 3. Connecting blocks 5 are slidably connected to the T-shaped rods 4. A first spring 6 is welded between one side of the connecting block 5 and the inner wall of the corresponding side of the T-shaped rod 4. The first spring 6 is movably sleeved on the T-shaped rod 4. A locking pin 7 is welded to the other side of the connecting block 5. Two mounting grooves 8 are provided at the end of the connecting pipe 3. A movable ring 9 is slidably connected to the pipe 3. Two hinge rods 10 are rotatably connected to one side of the movable ring 9. The ends of the hinge rods 10 are hinged to the other side of the corresponding connecting block 5. An extrusion die 11 is movably contacted at the end of the connecting pipe 3. Two mounting blocks 12 are fixedly connected to the end of the extrusion die 11. A slot 13 is provided on one side of the mounting block 12. The mounting block 12 is engaged with the corresponding mounting slot 8. The slot 13 is engaged with the corresponding locking pin 7. Support blocks 14 are welded to both sides of the connecting pipe 3. A positioning rod 15 is welded to one side of the support block 14. A connecting rod 16 is slidably connected to the positioning rod 15. The end of the connecting rod 16 is fixedly connected to the other side of the moving ring 9. Moving the moving ring 9 causes the connecting rod 16 to slide on the positioning rod 15. During the movement, the connecting rod 16 stretches the corresponding second spring 17. At the same time, the moving ring 9 drives the corresponding connecting block 5 to slide on the T-shaped rod 4 through the hinge rod 10. During the movement, the connecting block 5 compresses the corresponding first spring 6. Simultaneously, the connecting block 5 causes the corresponding locking pin 7 to separate from the locking groove 13. Then, the extrusion die 11 moves. Remove it, and then insert the mounting block 12 on the other extrusion die 11 into the mounting groove 8. When one side of the extrusion die 11 contacts the end of the connecting tube 3, release the force on the moving ring 9. At this time, the first spring 6, which is in a compressed state, returns to its original state. Under the action of the elastic force of the first spring 6, the first spring 6 drives the connecting block 5 to move. The connecting block 5 drives the locking pin 7 to engage with the corresponding locking groove 13, thereby fixing the other extrusion die 11. The extrusion die 11 can be replaced without the use of professional tools, and silicone strips of different specifications can be produced.
[0027] In some embodiments, a second spring 17 is fixedly connected between the other end of the connecting rod 16 and one side of the corresponding support block 14. The second spring 17 is movably sleeved on the corresponding positioning rod 15, and the positioning rod 15 serves a positioning function.
[0028] In some embodiments, a cooling box 18 is fixedly connected to the top of the workbench 1, and a refrigeration unit 19 is fixedly connected to the top of the cooling box 18.
[0029] In some embodiments, an air outlet hood 20 is fixedly connected to the top inner wall of the cooling box 18, and the output pipe of the refrigerator 19 extends into the cooling box 18 and is connected to and fixed to the air outlet hood 20.
[0030] In some embodiments, a plurality of guide rollers 21 are rotatably connected between the inner walls of the two sides of the cooling box 18, and rectangular holes 22 are provided on the inner walls of the left and right sides of the cooling box 18.
[0031] In some embodiments, a guide hole is provided on one inner wall of the mounting groove 8, and the inner wall of the guide hole is slidably connected to the outer side of the corresponding locking pin 7. The locking pin 7 serves to fix the device in place.
[0032] In operation, the material inside the main body 2 is extruded through the connecting pipe 3 and the extrusion die 11 via the main body 2. The extruded silicone strip is cooled by the refrigerator 19 through the rectangular hole 22 and by the air outlet hood 20. When the extrusion die 11 needs to be replaced, the moving ring 9 is moved. The moving ring 9 drives the connecting rod 16 to slide on the positioning rod 15. During the movement, the connecting rod 16 stretches the corresponding second spring 17. At the same time, the moving ring 9 drives the corresponding connecting block 5 to slide on the T-shaped rod 4 via the hinge rod 10. During the movement, the connecting block 5 compresses the corresponding first spring 6. Block 5 causes the corresponding locking pin 7 to separate from the slot 13. Then, the extrusion die 11 is moved and removed. Then, the mounting block 12 on the other extrusion die 11 is inserted into the mounting slot 8. When one side of the extrusion die 11 contacts the end of the connecting tube 3, the force on the moving ring 9 is released. At this time, the first spring 6, which is in a compressed state, returns to its original state. Under the action of its own elastic force, the first spring 6 drives the connecting block 5 to move. The connecting block 5 drives the locking pin 7 to engage with the corresponding slot 13, thereby fixing the other extrusion die 11. The extrusion die 11 can be replaced without the use of professional tools, and silicone strips of different specifications can be produced.
