Description

Technical Field

[0001] The invention relates to the technical field of cleaning machines, and more specifically to a waste plastic film friction cleaning machine. Background Art

[0002] Plastic cleaning equipment is developed by introducing and digesting advanced concepts and technologies of international peers, and combining the needs of today's social development and the characteristics of secondary applications of waste plastics. It can meet the environmental protection requirements of waste plastic recycling at home and abroad. The plastic cleaning machine mainly relies on the reamer installed on the rotating shaft inside the machine (it can be a plate or a steel rod) to strongly stir the material when rotating, generating friction between the knife and the material, and between the materials to achieve a cleaning effect.

[0003] At present, the original main shaft of the friction washing machine is welded to the blades. If the friction washing blades are worn, they cannot be replaced. When the friction washing blades are seriously worn, the main shaft can only be replaced, which is costly and cumbersome. When replacing the main shaft, it is equivalent to disassembling the entire equipment before replacement, which greatly increases the workload.

[0004] A Chinese patent with the authorization publication number CN215543222U discloses a plastic friction cleaning machine with a lifting function. By setting up a stirring and lifting component, that is, under the action of the auger, the material can be stably conveyed to the left, and the first blade and the second blade on the upper and lower sides of the main shaft can cooperate with each other to achieve efficient friction cleaning of the material. When the first blade and the second blade need to be quickly disassembled and replaced, the bolts connecting the first blade and the second blade can be unscrewed to complete the quick disassembly and assembly activities, thereby achieving the advantages of fully stirring and friction cleaning of the material and quick replacement of the friction blades.

[0005] Although this type of plastic friction cleaning machine with a lifting function can realize the quick disassembly and assembly of the blades, its fixing method still relies on traditional bolt fixing. In the case of narrow internal space of the equipment, this not only increases the difficulty of disassembly work, but also may affect maintenance efficiency and safety due to limited operating space. More importantly, the blades fixed only by bolts are at risk of falling off during high-speed rotation. This potential safety hazard may not only cause equipment damage, but also pose a threat to operators, seriously affecting production continuity and equipment reliability. Therefore, it is necessary to improve the fixing mechanism to improve safety and convenience. Summary of the invention

The inner shell 22 and the fixed shell 21 are correspondingly arranged in a plum blossom shape.

[0036] An airtight cavity 47 is provided at the rear side of the slide groove 43 , and a second insertion rod 48 is slidably connected inside the airtight cavity 47 . A connecting cavity 46 is provided between the airbag 45 and the airtight cavity 47 . A second slot 49 is provided on the inner wall of the slot 35 corresponding to the second insertion rod 48 .

[0037] A motor 15 is fixedly mounted on the right end face of the outer shell 1, and the output shaft of the motor 15 extends to the interior of the outer shell 1 and is fixedly connected to a rotating shaft 16. A feed port 12 is provided on the left end face of the outer shell 1, and a discharge port 13 is provided on the lower side of the right end face of the outer shell 1. Two sets of cover plates 18 are provided on the upper end face of the outer shell 1, and a drain pipe 14 is connected to the lower end face of the outer shell 1.

[0038] The convenient installation mechanism 2 also includes a latch assembly 5 arranged inside the inner shell 22. The latch assembly 5 includes a drive tube 52 fixedly installed on the lower end surface of the rotating barrel 26. A drive disk 51 is fixedly installed on the lower end of the drive tube 52. A transmission groove 53 is formed on the upper end surface of the drive disk 51. A slide rod 54 is slidably connected inside the transmission groove 53.

[0039] A limiting groove 55 is provided on the upper end surface of the fixed barrel 28 corresponding to the limiting groove 55, and the limiting groove 55 is internally slidably connected to a limiting block 56, and the limiting block 56 is fixedly connected to the sliding rod 54. A plug rod 3 57 is fixedly installed on the lower end of the sliding rod 54, and a slot 3 58 is provided on the inner wall of the fixed shell 21 corresponding to the plug rod 3 57, and an anti-slip component 4 is also arranged between the plug rod 3 57 and the slot 3 58.

[0040] Secondly, the rotation of the rotating barrel 26 will carry the driving disk 51 to rotate through the driving tube 52. The driving disk 51 has a transmission groove 53 opened on the upper end surface, so that the sliding rod 54 slidably connected inside the transmission groove 53 will synchronously follow the rotation of the driving disk 51 to move. The sliding rod 54 is fixedly connected to the limit block 56 slidably connected inside the limit groove 55. Therefore, the limit block 56 will guide the displacement direction of the sliding rod 54, so that the sliding rod 54 carries the plug rod 2 48 to move to the slot 2 49 on the fixed shell 21 and insert it. The synchronized multiple sets of plug rods 2 48 and slots 2 49 work together to install and fix.

[0041] The inside of the plug rod 1 33 and the plug rod 2 48 are both provided with an anti-slip part 4. When the plug rod 1 33 or the plug rod 2 48 is displaced, one end of the pull rope 1 42 is fixedly connected to the inner wall of the inner shell 22, thereby pulling the slide plate 44 slidably connected inside the slide groove 1 43 to be displaced, and the slide plate 44 will squeeze the air bag 45 inside the slide groove 1 43, so that the gas inside the air bag 45 passes through the connecting cavity 46 and enters the airtight cavity 47, thereby ejecting the plug rod 3 57 slidably connected inside the airtight cavity 47, and then following the plug rod 1 33 or the plug rod 2 48 to be inserted into the inside of the slot 3 58, the purpose of preventing the plug rod 1 33 and the plug rod 2 48 from slipping out.

[0042] The convenient installation mechanism 2 also includes a latch assembly 3 6 arranged on the lower side of the latch assembly 2 5, and the latch assembly 3 6 includes a rotating rod 61 arranged inside the driving tube 52, and the rotating rod 61 is rotatably connected to the polygonal column 25. A connecting member 62 is arranged on the lower side of the driving disk 51, and the lower end of the rotating rod 61 is fixedly connected to the connecting member 62.

[0043] A slot 63 is provided on the lower end surface of the inner shell 22, a fixed shaft 64 is fixedly installed inside the slot 63, a connecting rod 65 is rotatably connected to the outer surface of the fixed shaft 64, a sliding groove 2 66 is provided on the front end surface of the connecting rod 65, the fixed shaft 64 is slidably connected to the sliding groove 2 66, a fixed wedge block 68 is fixedly installed on the inner lower end surface of the fixed shell 21, a plug rod 4 67 is fixedly installed on the lower end of the connecting rod 65, and a slot 4 69 is provided on the outer surface of the fixed wedge block 68.

[0044] The latch assembly three 6 includes an auxiliary part 7 arranged inside the connecting rod 65, and the auxiliary part 7 includes a guide cavity 2 71 opened inside the connecting rod 65, and a pull rope 2 72 is slidably connected inside the guide cavity 2 71. A storage cavity 73 is opened on the lower end surface of the connecting rod 65, and the storage cavity 73 is communicated with the guide cavity 2 71. A storage block 74 is slidably connected inside the storage cavity 73, and a limit plate 75 is fixedly installed on the lower end of the storage block 74.

[0045] The upper end of the pull rope 72 extends to the upper side of the guide cavity 71 and is fixedly connected to the insertion rod 57 , and the lower end of the pull rope 72 extends to the interior of the storage cavity 73 and is fixedly connected to the storage block 74 .

[0046] Furthermore, the rotating cover 23 is connected to the outer wall of the inner shell 22 by a spiral transmission through the threaded groove 24, so the rotating cover 23 will gradually rise and carry the rotating rod 61 up through the polygonal column 25. The rotating rod 61 is rotatably connected to the polygonal column 25, so the rotating rod 61 will only carry the connecting member 62 up without rotating. The connecting member 62 is rotatably connected to the fixed shaft 64 fixedly installed inside the notch 63, so the upper end of the connecting rod 65 rises with the rising of the connecting member 62, thereby causing the connecting rod 65 to deflect around the fixed shaft 64, and the fixed shaft 64 will also move in the second slide groove 66. Internal sliding offsets the contradiction between the deflection force and the upward force. The insertion rod 467 fixedly installed at the lower end of the connecting rod 65 will be inserted into the slot 469 on the fixed wedge block 68 fixedly installed on the lower end surface of the fixed shell 21 as the connecting rod 65 deflects. Secondly, when the insertion rod 48 moves outward, it will pull one end of the pull rope 2 72 to move outward synchronously. Then, the storage block 74 fixedly installed at the other end of the pull rope 2 72 will retract inside the storage cavity 73, and carry the limit plate 75 back, and follow the deflection of the connecting rod 65 to clamp the limit plate 75 on the fixed wedge block 68 for fixation.

[0047] At present, the original main shaft of the friction cleaning machine is welded with the blade 17. If the friction cleaning blade 17 cannot be replaced after being worn, when the friction cleaning blade 17 is seriously worn, the main shaft can only be replaced, which is costly and cumbersome to replace. When replacing the main shaft, it is equivalent to disassembling the entire equipment before replacing it, which greatly increases the workload. The blade 17 fixing method of some existing equipment still relies on traditional bolt fixing. In the case of narrow internal space of the equipment, this not only increases the difficulty of disassembly, but also may affect maintenance efficiency and safety due to limited operating space. More importantly, the blade 17 fixed only by bolts has the risk of falling off during high-speed rotation. This potential safety hazard may not only cause equipment damage, but also pose a threat to operators, seriously affecting production continuity and equipment reliability. Therefore, this scheme starts to disassemble the blade 17 by setting a convenient installation mechanism 2. The blade 17 can be disassembled and installed by twisting the rotating cover 23. During installation, the fixed installation of the blade 17 is locked by utilizing the self-locking property of the threaded structure to prevent the blade 17 from detaching during high-speed rotation.

[0048] Method of use: When the blade 17 needs to be installed, the inner shell 22 at the bottom end of the blade 17 is inserted into the fixed shell 21 fixedly installed on the outer surface of the rotating shaft 16. The inner shell 22 and the fixed shell 21 are both arranged in a plum blossom shape. After the inner shell 22 is inserted into the fixed shell 21, the rotating cover 23 is manually rotated to make the rotating cover 23 carry the polygonal column 25 to rotate, and the polygonal column 25 is slidably connected with the polygonal groove 27 provided on the upper end surface of the rotating barrel 26, so that the rotating barrel 26 will be synchronously driven to rotate. The rotation of the rotating barrel 26 will carry the slider 1 31 to rotate, so that the slider 1 31 and the slider 2 32 collide and squeeze each other, so that the slider 2 32 moves outward, and the insertion rod 1 33 on the slider 2 32 will be inserted into the slot 1 35 provided on the fixed shell 21. There are multiple groups of the insertion rod 1 33 and the slot 1 35, which are inserted synchronously for preliminary installation and fixation.

[0049] Secondly, the rotation of the rotary barrel 26 will carry the driving disk 51 to rotate through the driving tube 52. The driving disk 51 has a transmission groove 53 provided on the upper end surface, so that the sliding rod 54 slidably connected inside the transmission groove 53 will move synchronously with the rotation of the driving disk 51, and the sliding rod 54 is fixedly connected to the limit block 56 slidably connected inside the limit groove 55. Therefore, the limit block 56 will guide the displacement direction of the sliding rod 54, so that the sliding rod 54 carries the second plug rod 48 to move to the second slot 49 on the fixed shell 21 and insert it. The synchronized multiple groups of second plug rods 48 and the second slot 49 work together to install and fix.

[0050] The inside of the plug rod 1 33 and the plug rod 2 48 are both provided with an anti-dropping member 4. When the plug rod 1 33 or the plug rod 2 48 is displaced, one end of the pull rope 1 42 is fixedly connected to the inner wall of the inner shell 22, so that the slide plate 44 slidably connected inside the slide groove 1 43 is pulled to move, and the slide plate 44 squeezes the air bag 45 inside the slide groove 1 43, so that the gas inside the air bag 45 passes through the connecting cavity 46 and enters the airtight cavity 47, thereby ejecting the plug rod 3 57 slidably connected inside the airtight cavity 47, and then following the plug rod 1 33 or the plug rod 2 48 into the inside of the slot 3 58, the plug rod 1 33 and the plug rod 2 48 are prevented from dropping out.

[0051] Furthermore, the rotating cover 23 is connected to the outer wall of the inner shell 22 by a spiral transmission through the thread groove 24, so the rotating cover 23 will gradually rise and carry the rotating rod 61 up through the polygonal column 25. The rotating rod 61 is rotationally connected to the polygonal column 25, so the rotating rod 61 will only carry the connecting member 62 up without rotating. After the rising is completed, the rotating cover 23 is locked by the self-locking property of the thread structure. A connecting rod 65 is rotationally connected between the connecting member 62 and the fixed shaft 64 fixedly installed inside the notch 63. Therefore, the upper end of the connecting rod 65 rises with the rising of the connecting member 62, thereby causing the connecting rod 65 to deflect around the fixed shaft 64 while the fixed shaft 64 is fixedly installed. The fixed shaft 64 will also slide inside the slide groove 26 to offset the contradiction between the deflection force and the lifting force. The insertion rod 467 fixedly installed at the lower end of the connecting rod 65 will be inserted into the slot 469 on the fixed wedge block 68 fixedly installed on the lower end surface of the fixed shell 21 as the connecting rod 65 deflects. Secondly, when the insertion rod 248 moves outward, it will pull one end of the pull rope 272 to move outward synchronously. Then, the storage block 74 fixedly installed at the other end of the pull rope 272 will retract inside the storage cavity 73, and carry the limit plate 75 back, and follow the deflection of the connecting rod 65 to clamp the limit plate 75 on the fixed wedge block 68 for fixation.

[0052] The above is only a preferred specific implementation of the present invention; however, the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and its improved conception within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
