Description

Technical Field

[0001] This utility model relates to the technical field of twin-screw extruders, specifically to a twin-screw extruder that is easy to disassemble and clean. Background Technology

[0002] A twin-screw extruder is a processing equipment used in the field of material processing. It is widely used in the molding and processing of extruded products. During use, the active screw drives the driven screw to rotate in the opposite direction, and the material is pushed to flow through the screw groove. It has the characteristics of high efficiency, high output and high quality.

[0003] Traditional twin-screw extruders use a feed hopper to deliver material into the extruder for processing, which makes it difficult to clean the material adhering to the inner wall of the feed hopper afterwards. Therefore, we propose a twin-screw extruder that is easy to disassemble and clean, thus addressing the aforementioned problems. Utility Model Content

[0004] The purpose of this invention is to provide a twin-screw extruder that is easy to disassemble and clean, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a twin-screw extruder that is easy to disassemble and clean, comprising a worktable, an extrusion box installed at the top of the worktable, a smoke exhaust pipe installed on one side of the top of the extrusion box, a discharge seat installed on the right side of the extrusion box, conveying screws installed on both sides inside the extrusion box, a third gear installed on the left side of the front conveying screw of the extrusion box, a second gear installed on the left side of the rear conveying screw of the extrusion box, a first gear provided at the bottom of the second gear, and a servo motor installed on one side of the first gear, a feed pipe installed on the left side of the top of the extrusion box, a mounting base installed on the outer wall of the feed pipe, and a guide seat installed at the top of the mounting base, grooves provided at both the front and rear ends of the mounting base, a locking block movably provided inside the groove, and one end of the locking block being fixed to the outer wall of the feed pipe, and a fixing ring hinged to the outer wall of the mounting base.

[0006] Preferably, the cross-section of the mounting base is smaller than the cross-section of the feed pipe, and the mounting base and the feed pipe form an engaging structure.

[0007] Preferably, there are two sets of fixing rings and locking blocks, and the two sets of fixing rings and locking blocks form an engaging structure.

[0008] Preferably, the first gear meshes with the third gear, and the third gear meshes with the second gear.

[0009] Preferably, the inner wall of the extrusion box is uniformly coated with a high-temperature resistant coating, and one end of the high-temperature resistant coating is provided with an anti-corrosion coating.

[0010] Preferably, a purification box is installed inside the exhaust pipe, and the purification box is filled with purification material. An exhaust port is installed at the top of the purification box.

[0011] Preferably, the cross-section of the purification box is smaller than the cross-section of the exhaust pipe, and the purification box and the exhaust pipe form an interlocking structure.

[0012] Preferably, the bottom end of the outer wall of the exhaust port is uniformly provided with external threads, and the top end of the interior of the purification box is uniformly provided with internal threads, and the exhaust port and the purification box form a threaded connection.

[0013] Compared with the prior art, the beneficial effects of this utility model are: the easy-to-disassemble and clean twin-screw extruder not only makes it easy to disassemble and clean the guide seat and scrape the material adhering to the inner wall of the extrusion box, but also has the function of purifying flue gas. When the extruder is in use, the material is fed into the extrusion box through the guide seat. After the extrusion work is completed, some material will stick to the inner wall of the guide seat, which is not easy to clean. By setting up components such as mounting seat, groove, clamping block and fixing ring between the guide seat and the feed pipe, the guide seat can be disassembled and removed for easy cleaning, making it more convenient to use. By providing an anti-corrosion coating and a high-temperature resistant coating on the inner wall of the extrusion box, the anti-corrosion coating has a certain degree of corrosion resistance and the high-temperature resistant coating has a certain degree of high-temperature resistance. After the anti-corrosion coating and the high-temperature resistant coating are provided on the inner wall of the extrusion box, the extrusion box has a certain degree of high-temperature resistance and corrosion resistance, thereby greatly increasing the protection of the extrusion box. By incorporating components such as exhaust ports, purification boxes, and purification materials inside the exhaust pipe, the conveying screw in the extrusion box generates a certain amount of smoke when it rotates to transport materials. This smoke is discharged through the exhaust pipe. Because of the aforementioned components, harmful substances in the smoke can be purified, making the smoke discharged into the air cleaner and more environmentally friendly.

[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 This utility model provides an embodiment of an easily disassembled and cleaned twin-screw extruder, comprising a worktable 1, an extrusion box 7 mounted on the top of the worktable 1, an exhaust pipe 6 mounted on one side of the top of the extrusion box 7, a discharge seat 8 mounted on the right side of the extrusion box 7, conveying screws 16 mounted on both sides inside the extrusion box 7, a third gear 15 mounted on the left side of the front conveying screw 16 of the extrusion box 7, a second gear 14 mounted on the left side of the rear conveying screw 16 of the extrusion box 7, a first gear 3 disposed at the bottom of the second gear 14, the first gear 3 meshing with the third gear 15, the third gear 15 meshing with the second gear 14, and a servo motor 2 mounted on one side of the first gear 3. A feed pipe 10 is installed on the left side of the feed pipe 10. A mounting base 9 is installed on the outer wall of the feed pipe 10, and a guide seat 4 is installed on the top of the mounting base 9. A groove 11 is provided at both the front and rear ends of the mounting base 9. A locking block 12 is movably installed inside the groove 11, and one end of the locking block 12 is fixed to the outer wall of the feed pipe 10. A fixing ring 13 is hinged to the outer wall of the mounting base 9. The cross-section of the mounting base 9 is smaller than the cross-section of the feed pipe 10. The mounting base 9 and the feed pipe 10 form a locking structure, so that the guide seat 4 is stably installed above the feed pipe 10. There are two sets of fixing rings 13 and locking blocks 12. The two sets of fixing rings 13 and locking blocks 12 form a locking structure, which facilitates the installation and disassembly of the guide seat 4. Specifically, such as Figure 1 , Figure 2 and Figure 3As shown, when disassembling the guide seat 4, flip the retaining ring 13 to disengage it from the outer wall of the locking block 12 and open the limit. Then, pull the guide seat 4 upwards so that the mounting seat 9 at its bottom end moves out from the outer wall of the feed pipe 10. This allows the guide seat 4 to be removed from the extruder for cleaning. After cleaning, align the mounting seat 9 at the bottom end of the guide seat 4 with the feed pipe 10 and engage it. Then, flip the retaining ring 13 in the opposite direction to engage it with the locking block 12. This allows the guide seat 4 to be reinstalled for normal use.

[0018] The inner wall of the extrusion box 7 is uniformly coated with a high-temperature resistant coating 18, and one end of the high-temperature resistant coating 18 is provided with an anti-corrosion coating 17. Specifically, such as Figure 4 As shown, a high-temperature resistant coating 18 is uniformly coated on the inner wall of the extrusion box 7, which increases the high-temperature resistance of the extrusion box 7 and makes it less prone to damage when conveying high-temperature materials. At the same time, an anti-corrosion coating 17 is also uniformly coated, which gives the extrusion box 7 a certain degree of corrosion resistance, making it less prone to damage when conveying some corrosive materials.

[0019] The exhaust pipe 6 has a purification box 19 installed inside, and the purification box 19 is filled with purification material 20. The top of the purification box 19 has an exhaust port 5. The cross-section of the purification box 19 is smaller than that of the exhaust pipe 6. The purification box 19 and the exhaust pipe 6 form a snap-fit ​​structure, which allows the purification box 19 to be disassembled and installed. The bottom of the outer wall of the exhaust port 5 is uniformly provided with external threads, and the top of the inside of the purification box 19 is uniformly provided with internal threads. The exhaust port 5 and the purification box 19 form a threaded connection, which allows the purification box 19 to be opened and the purification material 20 inside to be replaced. Specifically, such as Figure 1 and Figure 5 As shown, when the exhaust pipe 6 is in use, the flue gas in the extrusion box 7 is discharged through the exhaust pipe 6. When discharged, the purification material 20 inside the purification box 19 in the exhaust pipe 6 will purify the flue gas, making the flue gas clean and then discharged through the exhaust port 5. Subsequently, the purification box 19 can be pulled out from inside the exhaust pipe 6, and then the exhaust port 5 can be rotated to open the purification box 19, so that the purification material 20 inside can be taken out and replaced.

[0020] Working principle: When in use, the material enters the extrusion box 7 through the guide seat 4. At the same time, the servo motor 2 is started to drive the first gear 3 to rotate. The rotation of the first gear 3 drives the third gear 15 to rotate, and the rotation of the third gear 15 drives the second gear 14 to rotate. The rotation of the second gear 14 and the third gear 15 drives the conveying screw 16 to rotate in opposite directions. The material is pushed to flow through the screw groove, so that the material is squeezed out from the discharge seat 8. The smoke generated when the material is squeezed out is discharged through the exhaust pipe 6. The purification material 20 inside the purification box 19 in the exhaust pipe 6 will purify the smoke. After the smoke becomes clean, it is discharged through the exhaust port 5. After the extruder completes its work, the fixing ring 13 is flipped to disengage from the outer wall of the clamping block 12 to open the limit. Then, the guide seat 4 is pulled upward to move the mounting seat 9 at its bottom end out from the outer wall of the feed pipe 10. The guide seat 4 is then removed from the extruder for cleaning. After the guide seat 4 is cleaned, it is reinstalled in its original position for continued use.

[0021] 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. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
