Furthermore, "first" and "second" are only for descriptive purposes and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "multiple" means two or more.
[0026] Please seeFigures 1 to 5 As shown, this utility model provides a dual-color LED strip extruder, including a cavity 1, a torque adjusting shaft 2, a die 3, and an extruder 4. A guide member 5 is sleeved on the torque adjusting shaft 2, and the guide member 5 is located inside the cavity 1 and is used to guide the flow of raw materials. The extruder 4 is located at one end of the cavity 1, and one end of the torque adjusting shaft 2 is connected to the die 3. The die 3 is located inside the extruder 4, and the die 3 and the extruder 4 cooperate to extrude the dual-color LED strip. An axial torque adjusting assembly 6 is provided at the other end of the torque adjusting shaft 2, and the axial torque adjusting assembly 6 is used to limit the torque adjusting shaft 2 to move only axially. The end of the guide member 5 is provided with a mounting plate 51 fixedly connected to the cavity 1. The axial torque adjusting assembly 6 includes a torque adjusting plate 61 threadedly connected to the torque adjusting shaft 2, two first screws 62 slidably connected to the torque adjusting plate 61, and two second screws 63 threadedly connected to the torque adjusting plate 61. The first screws 62 are threadedly connected to the mounting plate 51, and the second screws 63 abut against the mounting plate 51.
[0027] In use, the die head 3 and the torque adjustment plate 61 are respectively installed on the torque adjustment shaft 2. Then, the torque adjustment shaft 2 is inserted into the guide member 5, and the two first screws 62 are screwed into the mounting plate 51. The torque adjustment shaft 2 is rotated to position the die head 3 upright. Finally, the two second screws 63 are screwed in so that their ends abut against the mounting plate 51 to fix the positions of the torque adjustment shaft 2 and the die head 3. When axial fine-tuning of the torque adjustment shaft 2 is required, such as... Figure 4 , 5 As shown, unscrew the first screw 62 a short distance, then screw in the second screw 63. With the end of the second screw 63 abutting against the mounting plate 51, the torque adjusting plate 61 moves backward, thereby driving the torque adjusting shaft 2 to move backward a short distance. After adjustment, tighten the first screw 62 again to lock the position of the torque adjusting plate 61, achieving a fine adjustment of the mold head 3 moving backward. Similarly, unscrew the second screw 63 a short distance, so that the end of the second screw 63 is away from the torque adjusting plate 61, then screw in the first screw 62 to push the torque adjusting plate 61 forward a short distance. After adjustment, screw in the second screw 63 so that the end of the second screw 63 abuts against the torque adjusting plate 61 again, locking the position of the torque adjusting plate 61, achieving a fine adjustment of the mold head 3 moving forward.
[0028] By setting the axial torque adjustment component 6, it is ensured that the torque adjustment shaft 2 only moves axially during adjustment and does not rotate circumferentially. This ensures that the die head 3 only adjusts its position in the front and rear directions during operation, and the adjustment amount of the first screw 62 and the second screw 63 is small for each rotation, thereby improving the adjustment accuracy and avoiding the situation where the die head 3 collides with the extrusion seat 41 and is damaged.
[0029] In a preferred embodiment, the two first screws 62 are symmetrically arranged; the two second screws 63 are symmetrically arranged. Preferably, the two first screws 62 and the two second screws 63 are arranged in a circumferential array. This arrangement ensures that the torque adjusting shaft 2 moves only axially.
[0030] In a preferred embodiment, see [reference] Figure 2 The die head 3 is threadedly connected to the torque adjustment shaft 2 to facilitate the replacement of different dies 3. By cooperating with the special die head 3 and the extrusion seat 41, LED flexible light strips with different cross-sections can be processed. The torque adjustment shaft 2 is provided with a through hole 21 extending along its length direction. The through hole 21 is used for the LED light strip to pass through, so that the extruded raw material can wrap around the LED light strip with a specific cross-section, thereby realizing the processing of LED flexible light strips.
[0031] In a preferred embodiment, see [reference] Figure 2 , 3 4. The extrusion head 4 includes an extrusion seat 41 and an outer mold plate 42. The outer mold plate 42 is located on the side of the extrusion seat 41 away from the cavity 1. The cavity 1 is provided with a first feed port 11. The outer wall of the guide member 5 is provided with a first guide groove 52. The first guide groove 52 and the inner wall of the cavity 1 form a first feed channel. The first feed port 11 is connected to the first feed channel. During the extrusion molding process, the first feed port 11 is connected to a molten first color material a. The first color material a enters the first feed channel through the first feed port 11. A conical hole 12 is opened inside the cavity 1. The conical hole 12 extends into the extrusion seat 41. The conical hole 12 is provided to facilitate the forward flow of the first color material a. The outer mold plate 42 is provided with a forming hole 422. The forming hole 422 cooperates with the die head 3 to make the first color material a wrap around the LED light strip with a certain cross-sectional shape.
[0032] Further, see Figure 3 The extrusion seat 41 is provided with a second feed port 43, and the outer die plate 42 has an inner guide chamber 421. A second guide groove 411 extending into the guide chamber 421 is formed inside the extrusion seat 41, and the second guide groove 411 and the guide chamber 421 form a second feed channel. The second feed port 43 communicates with the second feed channel. Molten second-color material b is present outside the second feed port 43. The second-color material b enters the second feed channel through the second feed port 43. The forming hole 422 cooperates with the die head 3 to wrap the second-color material b around the first-color material a with a certain cross-sectional shape. Through the above arrangement, the LED flexible light strip has two colors.
[0033] Specifically, by using the die head 3 and the extrusion head 4 in combination, it is possible to process products such as... Figure 6The LED flexible light strip shown has a first color material a, which is transparent and wraps around the LED strip so that the light emitted by the LED strip can pass through the first color material a and be emitted outward. The end of the die head 3 has a first protrusion 31 extending to the forming hole 422. The first protrusion 31 cooperates with the forming hole 422 so that the first color material a wraps around the LED strip with a certain cross-sectional shape. The second color material b is milky white or other opaque color and wraps around the first color material a except for the light-emitting side, so that the LED flexible light strip has only one light-emitting side. The outer mold plate 42 has a second protrusion 423 located in the flow guiding chamber 421 to limit the flow direction of the second color material b, so as to ensure that the second protrusion 423 cooperates with the forming hole 422 so that the second color material b wraps around the first color material a with a certain cross-sectional shape and does not mix with the first color material a.
[0034] It should be noted that the die head 3 and extrusion head 4 are different for LED flexible light strips with different cross sections. Accordingly, the first protrusion 31, the flow guiding chamber 421 and the second protrusion 423 will also be different. The specific structure should be determined according to the LED flexible light strip to be processed. Therefore, the specific shapes of the first protrusion 31, the flow guiding chamber 421 and the second protrusion 423 will not be described in detail.
[0035] In a preferred embodiment, see [reference] Figure 2 , 4 It also includes a pressure cap 7 connected to the end of the cavity 1. The extrusion seat 41 is provided with a mounting part 44 inside the pressure cap 7. Four third screws 71 arranged in a circumferential array are threaded onto the pressure cap 7. The ends of the four third screws 71 abut against the outer wall of the mounting part 44. By screwing in or out the third screws 71 respectively, the mounting position of the extrusion seat 41 on the vertical plane can be adjusted so that the center of the extrusion seat 41 corresponds to the center of the die head 3.
[0036] Further, see Figure 2 The cavity 1 has several annular grooves 13 near the end of the extrusion seat 41, and each annular groove 13 is provided with a sealing ring 8. The sealing ring 8 abuts against the end of the extrusion seat 41 to improve the sealing between the cavity 1 and the extrusion seat 41 and prevent the raw material from seeping out through the gap between the cavity 1 and the extrusion seat 41.
[0037] It is understood that those skilled in the art can make equivalent substitutions or changes based on the technical solution and inventive concept of this utility model, and all such substitutions or changes should fall within the protection scope of the appended claims of this utility model.
