Description

Technical Field

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

[0002] Plastic cleaning equipment is developed by introducing, digesting and absorbing advanced concepts and technologies from 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 (which can be a plate or a steel rod) to strongly stir the material during rotation, generating friction between the knife and the material, and between the materials to achieve a cleaning effect.

[0003] At present, the original friction cleaning machine main shaft is welded to the blades. If the friction cleaning blades are worn, they cannot be replaced. When the friction cleaning blades are severely 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 replacing it, which greatly increases the workload.

[0004] The Chinese patent with 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, thereby achieving the advantages of sufficient stirring and friction cleaning of the material and quick replacement of the friction blades.

[0005] While this plastic friction cleaning machine with a lifting function allows for quick assembly and disassembly of blades, its fixing method still relies on traditional bolts. Given the cramped interior of the equipment, this not only increases the difficulty of disassembly but also compromises maintenance efficiency and safety due to the limited operating space. More importantly, blades secured solely by bolts present a risk of falling off during high-speed rotation. This potential safety hazard could not only damage the equipment but also pose a threat to operators, seriously impacting production continuity and equipment reliability. Therefore, improving the fixing mechanism to enhance safety and convenience is necessary. Summary of the Invention

A spring 34 is fixedly installed between the slider 2 32 and the inner wall of the inner shell 22. A slot 35 is provided on the inner wall of the fixed shell 21 corresponding to the insertion rod 1 33.

[0034] 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 respectively 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 opened on the upper end surface of the rotating barrel 26, so that the rotating barrel 26 will be driven to rotate synchronously. 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 opened on the fixed shell 21. There are multiple groups of insertion rod 1 33 and slot 1 35, which are inserted synchronously for preliminary installation and fixation.

[0035] The latch assembly 3 also includes an anti-slip component 4 arranged inside the insertion rod 33. The anti-slip component 4 includes a guide cavity 41 opened inside the insertion rod 33. A pull rope 42 is slidably connected to the inside of the guide cavity 41. One end of the pull rope 42 extends to the outside of the guide cavity 41 and is fixedly connected to the inner shell 22. One end of the guide cavity 41 is connected to a slide groove 43. A slide plate 44 is slidably connected to the inside of the slide groove 43. The other end of the pull rope is fixedly connected to the slide plate 44. An air bag 45 is fixedly installed between the slide plate 44 and the inner wall of the slide groove 43.

[0036] An airtight cavity 47 is provided at the rear side of the slide groove 1 43 , and a second insertion rod 48 is slidably connected to the inside of the airtight cavity 47 . A connecting cavity 46 is provided between the airbag 45 and the airtight cavity 47 , and a second slot 49 is provided on the inner wall of the slot 1 35 corresponding to the second insertion rod 48 .

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

[0038] The convenient installation mechanism 2 also includes a latch assembly 2 5 arranged inside the inner shell 22. The latch assembly 2 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 provided 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 internal sliding connection of the limiting block 56 of the limiting groove 55 is fixedly connected to the sliding rod 54. The lower end of the sliding rod 54 is fixedly installed with an insertion rod 3 57, and a slot 3 58 is provided on the inner wall of the fixed shell 21 corresponding to the insertion rod 3 57, and an anti-slip component 4 is also provided between the insertion rod 3 57 and the slot 3 58.

[0040] 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 uses the transmission groove 53 opened on the upper end surface to make the sliding rod 54 slidingly connected inside the transmission groove 53 to move synchronously with the rotation of the driving disk 51, and the sliding rod 54 is fixedly connected to the limit block 56 slidingly 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 insertion rod 2 48 to move toward the slot 2 49 on the fixed shell 21 and insert it. The synchronized multiple groups of insertion rods 2 48 and slots 2 49 work together to install and fix them.

[0041] Anti-slip parts 4 are provided inside the insertion rod 1 33 and the insertion rod 2 48. When the insertion rod 1 33 or the insertion 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 displace, 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 insertion rod 3 57 slidably connected inside the airtight cavity 47, and then following the insertion rod 1 33 or the insertion rod 2 48 into the interior of the slot 3 58, thereby preventing the insertion rod 1 33 and the insertion 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. The latch assembly 3 6 includes a rotating rod 61 arranged inside the drive tube 52. The rotating rod 61 is rotatably connected to the polygonal column 25. A connecting member 62 is provided on the lower side of the drive disk 51. 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, and 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 second slide groove 66 is provided on the front end surface of the connecting rod 65. The fixed shaft 64 is slidably connected to the second slide groove 66. A fixed wedge 68 is fixedly installed on the inner lower end surface of the fixed shell 21, and a fourth insertion rod 67 is fixedly installed at the lower end of the connecting rod 65. A fourth slot 69 is provided on the outer surface of the fixed wedge 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 second pull rope 72 extends to the upper side of the second guide cavity 71 and is fixedly connected to the third insertion rod 57 , and the lower end of the second 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. A connecting rod 65 is rotatably 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 as the connecting member 62 rises, 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 4 67 fixedly installed at the lower end of the connecting rod 65 will be inserted into the slot 4 69 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 2 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] The main shaft of existing friction cleaning machines is welded to the blades 17. If the friction cleaning blades 17 become worn, they cannot be replaced. When the friction cleaning blades 17 become severely worn, the main shaft must be replaced, which is costly and cumbersome. Replacing the main shaft is equivalent to disassembling the entire machine, significantly increasing the workload. Furthermore, some existing machines still rely on traditional bolt fastening for blade 17. This not only increases the difficulty of disassembly in the confined space within the machine, but also compromises maintenance efficiency and safety due to the limited operating space. More importantly, blades 17 secured solely by bolts risk falling off during high-speed rotation. This potential safety hazard not only damages the machine but also poses a threat to operators, seriously impacting production continuity and equipment reliability. Therefore, this solution incorporates a convenient installation mechanism 2 to initiate the removal of the blades 17. The blades 17 can be removed and installed by simply twisting the rotating cover 23. During installation, the self-locking nature of the threaded structure locks the blades 17 in place, preventing them from falling off during high-speed rotation.

[0048] Instructions for 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 respectively 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 is 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 drive the driving plate 51 to rotate through the driving tube 52. The driving plate 51 passes through the transmission groove 53 opened 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 plate 51. 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 insertion rod 48 to move toward the second slot 49 on the fixed shell 21 and insert it. The synchronized multiple sets of second insertion rods 48 and second slots 49 work together to install and fix them.

[0050] The inside of the insertion rod 1 33 and the insertion rod 2 48 are both provided with an anti-slip part 4. When the insertion rod 1 33 or the insertion 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 displace. 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 insertion rod 3 57 slidably connected inside the airtight cavity 47, and then following the insertion rod 1 33 or the insertion rod 2 48 into the interior of the slot 3 58, thereby preventing the insertion rod 1 33 and the insertion rod 2 48 from slipping 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 to rise 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 to rise without rotating. After the ascent is completed, the rotating cover 23 is locked by the self-locking property of the thread structure. A connecting rod 65 is rotatably 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 as the connecting member 62 rises, thereby causing the connecting rod 65 to deflect around the fixed shaft 64 while the fixed The fixed shaft 64 will also slide inside the slide groove 2 66 to offset the contradiction between the deflection force and the upward force. The insertion rod 4 67 fixedly installed at the lower end of the connecting rod 65 will be inserted into the slot 4 69 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 2 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.

[0052] The above description is merely a preferred embodiment of the present invention; however, the scope of protection of the present invention is not limited thereto. Any person skilled in the art who, within the technical scope disclosed by the present invention, makes equivalent substitutions or modifications based on the technical solutions and improved concepts of the present invention shall be covered by the scope of protection of the present invention.
