Description

Technical Field

[0001] This utility model relates to the field of extrusion die technology, and in particular to a rubber extruder. Background Technology

[0002] Rubber products play a crucial role in many fields, such as the automotive industry, construction industry, and electronic equipment. With the continuous development of these industries, the requirements for the quality and output of rubber products are also increasing. As one of the core equipment for rubber product production, the performance of the extrusion die of the rubber extruder directly affects the quality of the product and the production efficiency. While the existing rubber extruders can basically meet the daily use needs, there are still some shortcomings that need to be improved.

[0003] The extrusion dies used in widely used rubber extruders function to distribute the molten material from the extruder barrel well in the die flow channel so that it can be extruded and shaped at a uniform speed. However, in actual use, when it is necessary to adjust the shape of the extruded material, it is necessary to replace the extrusion die with one of the corresponding shape. In the process of replacing the die, not only is it necessary to use specific tools for disassembly and installation, but also a certain level of skill is required to ensure the accurate installation of the die and prevent the die from being misaligned. To address this issue, we propose a rubber extruder to solve the above problems. Utility Model Content

[0004] In order to overcome the defects of the prior art mentioned above, the inventors conducted in-depth research and, after a great deal of creative work, completed this utility model.

[0005] Specifically, the technical problem to be solved by this utility model is to provide a rubber extruder to solve the technical problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution:

[0007] A rubber extruder includes a base, a rubber extruder mounted on the base, a feed inlet at the top of the rubber extruder, and an extrusion tube at the front end of the rubber extruder. A control box is mounted on the side of the base. A sleeve is mounted below the extrusion tube. A movable inner cavity is formed inside the sleeve. A sliding column is installed in the movable inner cavity. The front end of the sliding column is connected to a mounting base via a connecting rod. Clamping rods are installed on the outer walls of both the upper and lower ends of the mounting base. A first extrusion die and a second extrusion die are respectively connected to the two sets of clamping rods. A pull handle is installed on the outer wall of the front end of the mounting base. A return spring is wound around the outside of the connecting rod. A positioning component is provided at the top end of the extrusion tube.

[0008] As an improved technical solution, the positioning component includes a collar, a groove, a rotating sleeve, and a positioning hoop. The front end of the extrusion tube is fixed with a collar, the bottom end of the collar is provided with a groove, the locking rod can enter the groove, the top end of the extrusion tube is installed with a rotating sleeve, and the front end of the rotating sleeve is rotatably connected to a positioning hoop.

[0009] As an improved technical solution, the two ends of the return spring are located on the outer wall of the slide column and the inner wall of the movable inner cavity, respectively, and the slide column is elastically connected to the inner wall of the movable inner cavity through the return spring.

[0010] As an improved technical solution, both the first extrusion die and the second extrusion die are provided with extrusion orifices of different shapes.

[0011] As an improved technical solution, the diameter of the sliding column is the same as the inner diameter of the movable inner cavity on the sleeve, and the sliding column and the movable inner cavity are slidably connected.

[0012] As an improved technical solution, the outer wall of the clamp rod is fully fitted with the inner wall of the groove on the collar.

[0013] As an improved technical solution, the outer wall of the rear end of the positioning hoop contacts the outer wall of the collar, and the positioning hoop also contacts the outer wall of the locking rod in the groove on the collar.

[0014] After adopting the above technical solution, the beneficial effects of this utility model are:

[0015] I. This utility model features a rotatable mounting base installed at the front end of the extrusion tube, on which a first extrusion die and a second extrusion die are mounted. When it is necessary to replace the die, the pull handle can be pulled to allow the mounting base to move the first extrusion die away from the front end of the extrusion tube. Then, the mounting base can be rotated to allow the first and second extrusion dies to be quickly swapped. The slide column, under the elastic force of the return spring, can move the second extrusion die quickly back to the front end of the extrusion tube, thereby quickly completing the die replacement, reducing the time required for die replacement, eliminating the need for special tools, and improving the convenience of die replacement.

[0016] II. This utility model has a collar installed at the front end of the extrusion tube, which allows the locking rod to enter the locking groove on the collar, thereby allowing the locking groove to quickly position the die head and prevent the die head from shifting. Furthermore, a rotatable positioning hoop is installed at the top end of the extrusion tube, which allows the positioning hoop to quickly rotate to the front end of the locking groove, thereby limiting the locking rod in the locking groove and ensuring the stability of the die head during use.

Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. Additionally, the technical solutions of the various embodiments can be combined with each other, but only on the basis of being achievable by those skilled in the art.

[0028] Figures 1 to 5 As shown, this embodiment provides a rubber extruder, including a base 1, a rubber extruder 2 mounted on the base 1, a feed port 3 located at the top of the rubber extruder 2, and an extrusion tube 4 located at the front end of the rubber extruder 2. A control box 6 is installed on the side of the base 1, and a sleeve 7 is installed below the extrusion tube 4. A movable inner cavity 8 is opened in the sleeve 7, and a sliding column 9 is installed in the movable inner cavity 8. The front end of the sliding column 9 is connected to a mounting base 11 through a connecting rod 10. A locking rod 12 is installed on the outer walls of both the upper and lower ends of the mounting base 11. A first extrusion die 5 and a second extrusion die 13 are respectively connected to the two sets of locking rods 12. A pull handle 14 is installed on the outer wall of the front end of the mounting base 11. A return spring 15 is wound around the outside of the connecting rod 10, and a positioning component is provided at the top end of the extrusion tube 4.

[0029] By installing a rotatable mounting base 11 at the front end of the extrusion tube 4, and mounting a first extrusion die 5 and a second extrusion die 13 on the mounting base 11, when it is necessary to change the die, the handle 14 can be pulled to allow the mounting base 11 to move the first extrusion die 5 away from the front end of the extrusion tube 4. Then, the mounting base 11 can be rotated to allow the first extrusion die 5 and the second extrusion die 13 to be quickly swapped in position. Under the elastic force of the return spring 15, the slide column 9 can move the second extrusion die 13 to the front end of the extrusion tube 4 quickly, thereby quickly completing the die replacement and reducing the time required for die replacement.

[0030] In other embodiments, the positioning assembly includes a collar 16, a slot 17, a rotating sleeve 18, and a positioning clamp 19. The front end of the extrusion tube 4 is fixed with a collar 16, and the bottom end of the collar 16 is provided with a slot 17. The locking rod 12 can enter the slot 17. The top end of the extrusion tube 4 is equipped with a rotating sleeve 18, and the front end of the rotating sleeve 18 is rotatably connected to the positioning clamp 19.

[0031] By installing a collar 16 at the front end of the extrusion tube 4, the locking rod 12 can enter the locking groove 17 on the collar 16, thereby allowing the locking groove 17 to quickly position the die head and prevent the die head from shifting. Furthermore, by installing a rotatable positioning clamp 19 at the top end of the extrusion tube 4, the positioning clamp 19 can quickly rotate to the front end of the locking groove 17, thereby limiting the locking rod 12 in the locking groove 17 and ensuring the stability of the die head during use.

[0032] like Figure 4 As shown, the two ends of the return spring 15 are located on the outer wall of the slide column 9 and the inner wall of the movable inner cavity 8, respectively. The slide column 9 is elastically connected to the inner wall of the movable inner cavity 8 through the return spring 15.

[0033] This design allows the return spring 15 outside the connecting rod 10 to continuously apply a backward elastic force to the slide column 9, so that the slide column 9 can drive the locking rod 12 on the mounting base 11 to move backward, and the locking rod 12 can be inserted into the slot 17 on the collar 16.

[0034] In other embodiments, the first extrusion die 5 and the second extrusion die 13 are provided with extrusion orifices of different shapes;

[0035] This design allows for the replacement of the first extrusion die 5 and the second extrusion die 13 according to actual needs, thereby effectively controlling the shape of the extruded material.

[0036] like Figure 4 As shown, the diameter of the sliding column 9 is the same as the inner diameter of the movable inner cavity 8 on the sleeve 7, and the sliding column 9 and the movable inner cavity 8 are slidably connected.

[0037] This design ensures that the sliding column 9 can rotate smoothly within the movable inner cavity 8 and allows the movable inner cavity 8 to move back and forth.

[0038] In other embodiments, the outer wall of the latch 12 is fully fitted with the inner wall of the latch groove 17 on the collar 16;

[0039] With this design, when the locking rod 12 enters the locking groove 17 on the collar 16, it can effectively prevent the locking rod 12 from shaking inside the locking groove 17, ensuring that the mold head can be installed in place.

[0040] like Figure 1 As shown, the outer wall of the rear end of the positioning clamp 19 contacts the outer wall of the collar 16, and the positioning clamp 19 also contacts the outer wall of the locking rod 12 in the slot 17 on the collar 16.

[0041] This design allows the positioning clamp 19 to provide a stable limiting effect on the locking rod 12 within the slot 17, ensuring the stability of the die head during use.

[0042] This utility model provides a rubber extruder, the specific working principle of which is as follows:

[0043] When the first extrusion die 5 needs to be replaced, first rotate the positioning clamp 19 180 degrees, allowing it to rotate away from the front end of the extrusion tube 4, releasing the restriction on the locking rod 12 inside the collar 16. Then, pull the handle 14 forward, causing the mounting base 11 to drive the two sets of locking rods 12 and the sliding column 9 to slide forward along the movable inner cavity 8, allowing the locking rod 12 to disengage from the slot 17 on the collar 16. Then, rotate the handle 14, causing the mounting base 11 to drive the sliding column 9 to rotate 180 degrees, allowing the first extrusion die 5 and the second extrusion die 13 to be replaced. After the positions are reversed, the tension on the pull handle 14 can be released, allowing the return spring 15 to release its elasticity and push the slide column 9 to move to the rear end. This allows the mounting base 11 to move the locking rod 12 on it to the rear end, so that the locking rod 12 connected to the second extrusion die 13 can enter the slot 17 on the collar 16, completing the installation and positioning of the second extrusion die 13. Then, the positioning clamp 19 is rotated in the opposite direction to rotate to the initial position, forming a limit on the locking rod 12 in the slot 17, thus completing the replacement of the second extrusion die 13. The operation is now complete.

[0044] The electrical components mentioned in this article are all electrically connected to an external main controller and industrial power supply, and the main controller can be a conventional known device such as a computer that provides control.

[0045] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
