Description

Technical Field

[0001] This invention relates to the field of rubber extruder technology, specifically to a screw assembly and disassembly protection device for a rubber extruder. Background Technology

[0002] Rubber extruders are a fundamental piece of equipment in the rubber industry and a key component affecting product quality, playing a vital role in the production of tires and rubber products. The development of rubber extruders abroad has progressed through stages including plunger extruders, screw-type hot-feed extruders, ordinary cold-feed extruders, main and auxiliary screw cold-feed extruders, cold-feed vented extruders, pin cold-feed extruders, and compound extruders.

[0003] In existing rubber extruders, disassembling the internal screw requires first removing the extruder's outer casing, then using a wrench to remove the bolts securing the screw to one side. Due to the limited space within the extruder where the screw is located, removing the bolts is laborious and inefficient, impacting the extruder's performance. Furthermore, different specifications of rubber extruders use different bolts, requiring different wrenches and further reducing efficiency. Additionally, the bolt sizes at the bottom of the bolts vary, causing them to fall inside the extruder during removal, hindering subsequent screw installation. Therefore, we propose a screw disassembly and installation protection device for rubber extruders. Summary of the Invention

The shape of the T-shaped rod 521 is adapted to the shape of the opening 531 and the rotating groove 532. A threaded rod 54 is provided inside the disassembly cylinder 5. A fifth driven bevel gear 541 is threadedly connected to the surface of the threaded rod 54. The fifth driven bevel gear 541 meshes with the second driving bevel gear 53. A connecting plate 55 is fixedly connected to one side surface of the threaded rod 54. A clamping block 6 is fixedly connected to one side surface of the connecting plate 55. A rotating column 61 is rotatably connected inside the clamping block 6. A third gear 612 is fixedly connected to the surface of the rotating column 61. A handle 611 is fixedly connected to one side surface of the rotating column 61. A toothed plate 62 is slidably connected inside the clamping block 6. The toothed plate 62 meshes with the third gear 612. A clamping head 621 is fixedly connected to the top of the toothed plate 62. A disassembly cylinder 5 is provided on the side surface of the extension rod 42 away from the rotating column 4. A groove 51 is opened on the side surface of the disassembly cylinder 5 away from the extension rod 42. A disassembly head 52 is provided inside the groove 51.

[0042] Rotating the handle 611 causes the third gear 612 to rotate via the rotating column 61. The third gear 612 causes the toothed plate 62 to rotate inside the clamping block 6, so that the toothed plate 62 moves the clamping head 621 to the appropriate position. The bolt drives the disassembly head 52 to rotate, and the disassembly head 52 drives the second driving bevel gear 53 to rotate via the T-shaped rod 521. The second driving bevel gear 53 drives the clamping block 6 to move via the threaded rod 54 and the connecting plate 55, thereby achieving the effect of easy adjustment.

[0043] Working principle: In use, move the main body 1 to the appropriate position, replace the disassembly head 52 according to the bolts used inside the rubber extruder, rotate the disassembly head 52 to make the T-shaped rod 521 rotate in the rotating groove 532, and take the T-shaped rod 521 out from the second driving bevel gear 53 through the opening 531. Place the disassembly head 52 of the appropriate size into the opening 531, and rotate the disassembly head 52 in the opposite direction to make the T-shaped rod 521 enter the interior of the rotating groove 532. Adjust the clamping block 6 according to the stud shape of the bolts inside the rubber extruder, rotate the handle 611, and the handle 611 drives the third gear 612 to rotate through the rotating column 61. The third gear 612 drives the toothed plate 62 to rotate inside the clamping block 6, so that the toothed plate 62 drives the clamping head 621 to move up and down to the appropriate position. Start the motor 2, and the motor 2 drives the first driving bevel gear 211 to rotate through the first rotating rod 21. The first driving bevel gear 211 drives the second rotating rod 13 through the first driven bevel gear 131. The rotation of the second rotating rod 13 drives the first gear 132 and the second driven bevel gear 133 to rotate. The first gear 132 drives the second tooth 41 on the surface of the rotating column 4 to rotate and move, so that the rotating column 4 drives the disassembly cylinder 5 to rotate and move through the extension rod 42. The second driven bevel gear 133 drives the third rotating rod 14 to rotate through the third driven bevel gear 141, so that the second gear 142 drives the storage cylinder 3 to move through the first tooth 31. The movement of the disassembly cylinder 5 causes the disassembly head 52 to contact the bolt, thereby removing the bolt. The bolt drives the disassembly head 52 to rotate. The disassembly head 52 drives the second driving bevel gear 53 to rotate through the T-shaped rod 521. The second driving bevel gear 53 drives the clamping block 6 to move through the threaded rod 54 and the connecting plate 55. Since the clamping block 6 and the clamping head 621 are U-shaped, the clamping head 621 and the clamping block 6 fix the stud. The screw falls into the storage cylinder 3. When installation is required, the control motor 2 is reversed to complete the above operation.

[0044] In summary, this screw disassembly and assembly protection device for a rubber extruder utilizes the cooperation between the rotating column 4 and the disassembly cylinder 5. The motor 2 drives the first driving bevel gear 211 via the first rotating rod 21. The first driving bevel gear 211 drives the second rotating rod 13 via the first driven bevel gear 131. The second rotating rod 13 drives the first gear 132 and the second driven bevel gear 133 to rotate. The first gear 132 drives the second teeth 41 on the surface of the rotating column 4 to rotate and move, causing the rotating column 4 to drive the disassembly cylinder 5 to rotate and move via the extension rod 42. The second driven bevel gear 133 drives the third rotating rod 14 via the third driven bevel gear 141 to rotate, causing the second gear 142 to drive the receiving cylinder 3 to move via the first teeth 31. The movement of the disassembly cylinder 5 brings the disassembly head 52 into contact with the bolt, thereby removing the bolt. The screw falls into the receiving cylinder 3. When installation is required, the motor 2 is reversed to complete the above operations, thus achieving the effect of easy disassembly and assembly. The head 52 works in conjunction with the second driving bevel gear 53. Rotating the head 52 causes the T-shaped rod 521 to rotate in the rotating groove 532. The T-shaped rod 521 is then removed from the second driving bevel gear 53 through the opening 531. A head 52 of the appropriate size is placed in the opening 531, and the head 52 is rotated in the opposite direction to allow the T-shaped rod 521 to enter the rotating groove 532, thus facilitating replacement. The clamping head 621 works in conjunction with the threaded rod 54. Rotating the handle 611 causes the third gear 612 to rotate via the rotating column 61. The third gear 612 causes the toothed plate 62 to rotate inside the clamping block 6, moving the clamping head 621 to the appropriate position. The bolt then rotates the head 52, which in turn drives the second driving bevel gear 53 to rotate via the T-shaped rod 521. The second driving bevel gear 53, through the threaded rod 54 and connecting plate 55, moves the clamping block 6, thus facilitating adjustment.
