Description

Technical Field

[0001] This invention belongs to the field of plastic component recycling technology, specifically relating to a biodegradable membrane crushing and recycling device. Background Technology

[0002] Biodegradable films are gradually replacing traditional plastic films due to their unique properties and are widely used in agriculture, packaging, and other fields. Although they can degrade naturally, their rate is affected by various factors, and large amounts of waste may still put pressure on the environment. Recycling equipment can effectively treat this waste and reduce pollution.

[0003] Chinese patent CN118832763A discloses a biodegradable membrane crushing and recycling device, including a frame and a hot-melt box. The beneficial effects of this invention are as follows: A retractable shearing blade repeatedly applies pressure to the highly elastic biodegradable membrane. If the membrane in this batch has high crystallinity, and the shearing blade continues to move before reaching its stroke, the pressure causes plasticizer in the storage tank to be injected into the hot-melt box for blending. The added dosage is proportional to its strength, thus better controlling the dosage of additives, improving the physical properties of the recycling process, and increasing recycling efficiency. Furthermore, compared to traditional methods, this biodegradable membrane crushing and recycling device, through the cooperation of a fine screening mechanism and a testing mechanism, can further refine and blend the biodegradable membranes to be crushed and recycled in the same batch with a single run of the hot-melt box. Each time the biodegradable membrane fragments enter the hot-melt box for reorganization, their suitable additives are re-injected, thus further improving the overall quality of recycling.

[0004] When the above-mentioned equipment is in use, the film enters the outer drum after the initial crushing and then enters the fine screening mechanism. This causes the screening cylinder of the fine screening mechanism to become clogged, making it inconvenient to clean. In addition, the equipment needs to be stopped during cleaning, which limits the processing efficiency. Summary of the Invention

[0018] I. This invention, through the coordinated operation of a linkage mechanism, a filtering mechanism, a driving mechanism, a vibration mechanism, and a conveying pipe, can move and rotate a filter plate 160° when it becomes clogged.

This enables continuous filtration of pulverized film fragments without stopping the equipment, thus improving the pulverization efficiency.

[0020] Third, the present invention, through its processing mechanism, allows the conical spiral blades to knead the pulverized and filtered film fragments after they enter the processing cylinder. As the number of film fragments increases, the blades will further pulverize the film fragments, thereby improving the fineness and uniformity of the film fragments and providing better raw materials for subsequent hot-melt recycling.

[0038] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0039] Reference Figures 1-8 As shown, the present invention provides a biodegradable film crushing and recycling device, including a crushing component 41 for recycling biodegradable plastic film and a recycling mechanism 1. A linkage mechanism 4 is arranged below the crushing component 41. A drive mechanism 6, a vibration mechanism 7 and a conveying pipe 8 are arranged symmetrically on both sides of the linkage mechanism 4. The drive mechanism 6 is located above the vibration mechanism 7. A filter mechanism 5 is arranged above the drive mechanism 6. A processing mechanism 3 is arranged outside the recycling mechanism 1.

[0040] The linkage mechanism 4, drive mechanism 6, vibration mechanism 7, and conveying pipe 8 are used for continuous processing of the filtration mechanism 5;

[0041] The processing mechanism 3 includes a processing cylinder 31, a stirring assembly 35, and a cover end 34. The cover end 34 is used to support the processing cylinder 31. The stirring assembly 35 includes a stirring shaft 351 and a conical spiral blade 352. The stirring assembly 35 is used to work with the processing cylinder 31 to rub and knead the film fragments. The processing cylinder 31, in conjunction with the stirring assembly 35, is also used to pulverize the film fragments a second time.

[0042] The linkage mechanism 4 includes a filter box 43, which has a through groove 44 extending from left to right. The through groove 44 is used to restrict the sliding of the filter mechanism 5.

[0043] The filtration mechanism 5 includes a receiving frame 51, a partition plate 53, and filter plates 592 symmetrically located on both sides of the partition plate 53. A limiting plate 57 is provided inside the partition plate 53. The limiting plate 57 is used to limit a single filter plate 592. The filter plate 592 is used to filter membrane fragments crushed by the crushing component 41.

[0044] The drive mechanism 6 includes a mounting bracket 61 and two drive racks 64, which are used to rotate the filter plate 592160°.

[0045] The vibration mechanism 7 includes a collection box 71, a linkage plate 73, and a receiving frame 75. The linkage plate 73 is used for indirect vibration treatment of the filter plate 592.

[0046] In a further embodiment, the filter plate 592 is fixedly connected to both sides by a shaft with a linkage gear 593, the linkage gear 593 is rotatably connected to the inner side of the receiving frame 51, the inner side of the receiving frame 51 is fixedly connected to an upper limit plate 54 above the filter plate 592, the middle partition plate 53 is fixedly connected to both sides below the filter plate 592 with a lower limit plate 55, and the limit plate 57 is located above the horizontal filter plate 592.

[0047] In this embodiment, the receiving frame 51 has a cavity at the rotatable connection of the linkage gear 593. This cavity is connected to the insertion slot 52, which facilitates the drive rack 64 to mesh with the linkage gear 593, thereby causing the filter plate 592 to rotate 160°.

[0048] In a further embodiment, insertion slots 52 are provided on both sides of the receiving frame 51. The drive rack 64 fits into the interior of the insertion slots 52. The drive rack 64 cooperates with the linkage gear 593. The mounting frame 61 is installed on one side of the collection box 71. Two electric cylinders 62 are installed above the mounting frame 61. The output end of the electric cylinder 62 is fixedly connected to the receiving plate 63. The drive rack 64 is fixedly connected to the receiving plate 63 through the connecting rod.

[0049] In this embodiment, the partition 53 divides the interior of the receiving frame 51 into two passages, and the upper limit plate 54, lower limit plate 55 and filter plate 592 inside the two passages are symmetrical. Due to the restriction of the upper limit plate 54 and lower limit plate 55, the filter plate 592 in the left passage can only rotate counterclockwise, while the filter plate 592 in the right passage can only rotate clockwise.

[0050] In a further embodiment, the partition plate 53 has a limiting groove 56, and the limiting plate 57 is slidably connected to the inside of the limiting groove 56. Magnetic blocks 45 are installed on both sides of the filter box 43, and a stepper motor 591 is installed on one side of the filter box 43. The output end of the stepper motor 591 is rotatably connected to the inside of the filter box 43.

[0051] In this embodiment, the stepper motor 591 can rotate in both directions, thereby allowing the receiving frame 51 to move left and right, so that one of the left and right passages of the receiving frame 51 is inside the filter box 43, thereby allowing the filter plate 592 inside the passage to perform filtration.

[0052] In a further embodiment, a rack 59 is fixedly connected to one side of the receiving frame 51. The rack 59 meshes with the output end of the stepper motor 591. A second magnetic block 58 is embedded inside the limiting plate 57. The second magnetic block 58 cooperates with the first magnetic block 45.

[0053] In this embodiment, the downward-facing sides of the magnetic blocks 45 on both sides of the filter box 43 are opposite polarities, that is, the bottom of the left magnetic block 45 is the N pole, and the bottom of the right magnetic block 45 is the S pole. The left side of the magnetic block 58 is the N pole and the right side is the S pole, so that the magnetic block 58 always repels the magnetic block 45, thereby keeping one side of the limiting plate 57 always inside the filter box 43. That is, at this time, the limiting plate 57 restricts the filter plate 592 located in the filter box 43, but releases another filter plate 592, so that the released filter plate 592 can rotate.

[0054] In a further embodiment, a filter box 43 is fixedly connected to one side of the collection box 71, a receiving frame 75 is located on the other side of the collection box 71, and a connecting rod 74 is fixedly connected to one side of both ends of the linkage plate 73. The connecting rod 74 is inserted into the inside of the collection box 71.

[0055] In this embodiment, the collection box 71 has an insertion slot on the connecting rod 74; the upper end of the linkage plate 73 has a beveled surface, so that it can better contact the filter plate 592 during the rotation process. When the elastic member 77 rebounds, the linkage plate 73 will be in the middle of the collection box 71. Due to the rotation of the filter plate 592, when the filter plate 592 rotates to ninety degrees, it will contact the linkage plate 73 and drive it to move together until the back of the linkage plate 73 presses against the sensor 72.

[0056] In a further embodiment, one end of the connecting rod 74 is fixedly connected to the receiving frame 75, a vibration motor 76 is installed above the receiving frame 75, an elastic element 77 is provided between the receiving frame 75 and the collection box 71, and a sensor 72 is embedded in the inner side wall of the collection box 71.

[0057] In this embodiment, when the sensor 72 is squeezed, it will send feedback to the controller, which will stop the electric cylinder 62 and start the vibration motor 76. After a certain period of time, the controller will first turn off the vibration motor 76 and then start the electric cylinder 62 so that the cleaned filter plate 592 returns to the horizontal position. The stepper motor 591 will only start when the other filter plate 592, which is filtering membrane fragments, becomes clogged.

[0058] In a further embodiment, the outer periphery of the conical spiral blade 352 is attached to the inner wall of the processing cylinder 31. Both ends of the conical spiral blade 352 are fixedly connected to connecting plates 353. The connecting plates 353 are sleeved and fixed to the outer periphery of the stirring shaft 351. The outer periphery of the stirring shaft 351 is fixedly connected to a spiral plate 356. A blade 355 is fixedly connected between the spiral plate 356 and the conical spiral blade 352. The outer periphery of the conical spiral blade 352 is provided with equally spaced notches 354. The notches 354 are used for film fragments to pass through. The blade 355 is used to further crush the film fragments when the amount of film fragments increases.

[0059] In this embodiment, when the drive motor 33 drives the stirring shaft 351 to rotate clockwise, the stirring shaft 351 will cause the conical spiral blade 352 to rotate synchronously through the connecting plate 353, so that the conical spiral blade 352 always pushes the incoming film fragments to the right, that is, to one side of the linkage mechanism 4. Since the inner wall of the processing cylinder 31 is conical and gradually decreases in size from left to right, the film fragments will slide to the left and pass through the notch 354, thereby generating friction with the film fragments that are moving to the right, thus making the kneading more fine. In addition, as the number of film fragments increases, the blade 355 will also perform secondary crushing of the film fragments.

[0060] In a further embodiment, a drive motor 33 is installed above the recycling mechanism 1. The output end of the drive motor 33 is engaged with one end of the stirring shaft 351. A cover end 34 is provided around the processing cylinder 31. The cover end 34 is used to seal both ends of the processing cylinder 31. A connecting pipe 32 is provided at one end of the processing cylinder 31 near the recycling mechanism 1. The connecting pipe 32 is connected to the recycling mechanism 1. One end of the conveying pipe 8 is connected to the bottom of the collection box 71, and the other end is located above the crushing component 41.

[0061] In this embodiment, the side of the cover end 34 near the linkage mechanism 4 is fixedly connected to the connecting pipe 42, and there is a support column outside the linkage mechanism 4; the collection box 71 is open from top to bottom, and there is a collection hopper at the bottom. The collection hopper is connected to one end of the conveying pipe 8, and a blower is provided at the conveying pipe 8, so as to re-transport the unqualified film fragments collected in the collection hopper to the inside of the crushing component 41.

[0062] In a further embodiment, a support 2 is provided on the outside of the recycling mechanism 1. The support 2 is used to support the processing cylinder 31. The cover end 34 is fixedly connected to the top of the support 2. A connecting pipe 42 is fixedly connected to one side of the cover end 34. The connecting pipe 42 is fixedly connected to the bottom of the filter box 43.

[0063] In this embodiment, the recycling mechanism 1 is a prior art device for hot-melt film fragments and can have additives added inside it; the crushing assembly 41 has a crushing roller inside and a motor for driving the crushing roller is installed on one side.

[0064] The working principle of this invention is as follows:

[0065] When the waste biodegradable film enters the crushing component 41, it can be crushed and then enters the processing cylinder 31 after passing through the filter box 43, the connecting pipe 42 and the stirring component 35 in sequence. Then, the control device causes the drive motor 33 to drive the stirring shaft 351 to rotate clockwise, kneading and crushing the film fragments. Then, the connecting pipe 32 is opened to transport the material to the recycling mechanism 1, where additives are added and the material is heated and melted for easy reuse.

[0066] When the membrane is crushed by the crushing component 41 and falls through the filter box 43, it passes through the filter plate 592, thereby filtering and making the debris more suitable for recycling. After a certain period of filtration, the filter plate 592 will become clogged. At this time, the control device will drive the stepper motor 591 to operate, so that the rack 59 carries the filter plates 592 on both sides of the receiving frame 51 and the partition plate 53 to the left side of the filter box 43, so that the filter plates 592 that were originally on the outside enter the interior of the filter box 43, and replace the clogged filter plate 592 with another unclogged filter plate 592, thus continuously filtering the membrane fragments.

[0067] During the leftward movement of the receiving frame 51, the drive rack 64 is inserted into the insertion slot 52. When the filter plate 592 on the right side is fully inserted into the filter box 43 for filtration, the control device will operate the electric cylinder 62 to move the receiving plate 63 to the right along with the drive rack 64. At this time, the drive rack 64 will mesh with the linkage gear 593, causing the filter plate 592 to rotate 160° counterclockwise, so that the filtering side of the filter plate 592 is tilted downward. During the rotation of the filter plate 592, it will contact and drive the linkage vertical plate 7. 3. Movement: When the filter plate 592 rotates to 160°, the linkage plate 73 will contact the sensor 72, thereby feeding back to the control device to make the vibration motor 76 operate and generate vibration. This vibration will cause the filter plate 592 to vibrate through the connecting rod 74 and the linkage plate 73, thereby causing the film residue remaining on the filter surface of the filter plate 592 to fall into the collection box 71 and then be transported back to the crushing assembly 41 by the conveying pipe 8 for further crushing. This allows the filter plate 592 that has been moved out to be cleaned, making it convenient for the next replacement.

[0068] During the leftward movement of the receiving frame 51, and when the partition plate 53 is in the through slot 44, the magnetic block 58 embedded in the inner side of the limiting plate 57 repels the magnetic block 45 from opposite sides, causing the magnetic block 45 to be pushed back by the magnetic force and move to the right. This makes the left side of the magnetic block 45 no longer restrict one side of the filter plate 592, thus facilitating the rotation of the filter plate 592. At the same time, the right side of the magnetic block 45 begins to restrict the other filter plate 592.

[0069] When the drive motor 33 drives the stirring shaft 351 to rotate clockwise, the stirring shaft 351 will cause the conical spiral blade 352 to rotate synchronously through the connecting plate 353, so that the conical spiral blade 352 will always push the incoming film fragments to the right (i.e., move closer to the side of the linkage mechanism 4). Since the inner wall of the processing cylinder 31 is conical and gradually decreases in size from left to right, the film fragments will slide to the left and pass through the notch 354, thus generating friction with the film fragments that are moving to the right, so that the kneading is more refined. In addition, as the number of film fragments increases, the blade 355 will also perform secondary crushing of the film fragments.

[0070] Although embodiments of the 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 invention, the scope of which is defined by the appended claims and their equivalents.
