Description

Technical Field

[0001] The invention belongs to the technical field of plastic component recycling, and in particular relates to a biodegradable film crushing and recycling device. Background Art

[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 be degraded naturally, their speed is affected by many factors, and large amounts of waste may still put pressure on the environment. Recycling equipment can effectively handle these wastes and reduce pollution.

[0003] In the Chinese patent with publication number CN118832763A, a biodegradable film crushing and recycling equipment is mentioned, including a frame and a hot melt box. The beneficial effects of the present invention are: the highly elastic biodegradable film is repeatedly pressurized by a retractable shearing knife. If the crystallinity of the batch of films is high, and the shearing knife continues to move before reaching the stroke, the pressure will cause the plasticizer in the liquid storage tank to be injected into the hot melt box for blending, and the added dosage is proportional to its strength, so as to better control the dosage of additives, improve the physical properties of the recycling process, and improve the recycling efficiency. In addition, compared with the traditional method, the biodegradable film crushing and recycling equipment can make fine blends of the biodegradable films to be crushed and recycled in the same batch through the cooperation of a fine screening mechanism and a testing mechanism in a single operation of the hot melt box. Each time the biodegradable film fragments enter the hot melt box for reorganization, the appropriate additives will be re-injected, thereby further improving the overall quality of the recycling.

[0004] When the above-mentioned device is in use, the film will enter the outer drum and then the fine screen mechanism after the initial crushing, which will cause the screening drum of the fine screen mechanism to be blocked, making it inconvenient to clean.

[0041] The linkage mechanism 4, the driving mechanism 6, the vibration mechanism 7 and the delivery pipe 8 are used for continuous treatment of the filtering mechanism 5;

[0042] 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 sheet 352. The stirring assembly 35 is used to cooperate with the processing cylinder 31 to rub and knead the film fragments. The processing cylinder 31 cooperates with the stirring assembly 35 to also be used for secondary crushing of the film fragments.

[0043] The linkage mechanism 4 includes a filter box 43, and the filter box 43 is provided with a through slot 44 which passes through the left and right sides, and the through slot 44 is used to limit the sliding of the filter mechanism 5;

[0044] The filter mechanism 5 includes a receiving frame 51, a middle partition plate 53 and filter plates 592 symmetrically located on both sides of the middle partition plate 53. A limit plate 57 is provided inside the middle partition plate 53. The limit plate 57 is used to limit a single filter plate 592. The filter plate 592 is used to filter the film fragments crushed by the crushing assembly 41.

[0045] The driving mechanism 6 includes a mounting frame 61 and two driving racks 64, and the driving racks 64 are used to rotate the filter plate 592160°;

[0046] The vibration mechanism 7 includes a collection box 71 , a linkage vertical plate 73 and a receiving frame 75 , and the linkage vertical plate 73 is used for indirectly vibrating the filter plate 592 .

[0047] In a further embodiment, the two sides of the filter plate 592 are fixedly connected with a linkage gear 593 through an axis, 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 located above the filter plate 592 and is fixedly connected with an upper limit plate 54, the two sides of the middle partition plate 53 are located below the filter plate 592 and are fixedly connected with a lower limit plate 55, and the limit plate 57 is located above the horizontal filter plate 592.

[0048] In this embodiment, the receiving frame 51 has a cavity at the rotation connection of the linkage gear 593, and the cavity is connected to the insertion groove 52, so as to facilitate the driving rack 64 to mesh with the linkage gear 593 to rotate the filter plate 592 160°.

[0049] In a further embodiment, plug-in grooves 52 are provided on both sides of both ends of the receiving frame 51, the driving rack 64 fits into the inside of the plug-in groove 52, the driving rack 64 cooperates with the linkage gear 593, the mounting frame 61 is installed on one side of the collecting box 71, and 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, and the driving rack 64 is fixedly connected to the receiving plate 63 through a connecting rod.

[0050] In this embodiment, the middle partition plate 53 divides the interior of the receiving frame 51 into two through openings, and the upper limit plate 54, the lower limit plate 55 and the filter plate 592 inside the two through openings are symmetrical. The filter plate 592 in the left through opening can only rotate counterclockwise due to the restrictions of the upper limit plate 54 and the lower limit plate 55, while the filter plate 592 in the right through opening can only rotate clockwise.

[0051] In a further embodiment, a limiting groove 56 is opened in the middle partition plate 53, and the limiting plate 57 is slidably connected to the inside of the limiting groove 56 left and right. 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 inner side of the filter box 43.

[0052] In this embodiment, the stepper motor 591 can rotate forward and reverse, so that the receiving frame 51 can move left and right, so that one of the left and right through-ports of the receiving frame 51 can be located inside the filter box 43, so that the filter plate 592 in the through-port can filter.

[0053] In a further embodiment, a rack 59 is fixedly connected to one side of the receiving frame 51 , and the rack 59 is meshedly connected to the output end of the stepper motor 591 . A magnetic block 2 58 is embedded inside the limiting plate 57 , and the magnetic block 2 58 cooperates with the magnetic block 1 45 .

[0054] In this embodiment, the downward facing sides of the magnetic blocks 45 on both sides of the filter box 43 are opposite poles, that is, the lower side of the left magnetic block 45 is the N pole, and the lower side of the right magnetic block 45 is the S pole, and the left side of the magnetic block 2 58 is the N pole and the right side is the S pole, so that the magnetic block 2 58 always repels the magnetic block 1 45, and then one side of the limiting plate 57 is always on the inner side of the filter box 43, that is, at this time, the limiting plate 57 limits the filter plate 592 located in the filter box 43, but releases the other filter plate 592, so that the released filter plate 592 can rotate.

[0055] In a further embodiment, one side of the collecting box 71 is fixedly connected to the filter box 43, the receiving frame 75 is located on the other side of the collecting box 71, and one side of the two ends of the linkage vertical plate 73 is fixedly connected with a connecting rod 74, which is inserted into the interior of the collecting box 71.

[0056] In this embodiment, the collection box 71 is provided with a plug-in slot on the connecting rod 74; the upper end of the linkage vertical plate 73 has a chamfered surface so that it can better contact with the filter plate 592 during the rotation process. When the elastic member 77 rebounds, the linkage vertical plate 73 will be located 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 vertical plate 73 and drive it to move together until the back of the linkage vertical plate 73 is squeezed against the sensor 72.

[0057] 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 member 77 is arranged between the receiving frame 75 and the collecting box 71, and a sensor 72 is embedded in the inner wall of the collecting box 71.

[0058] In this embodiment, when the sensor 72 is squeezed, it will feed back to the controller, so that the controller stops the electric cylinder 62 and starts 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 to make the cleaned filter plate 592 return to the horizontal state, and wait for another filter plate 592 that is filtering film fragments to be blocked before the stepper motor 591 will start.

[0059] In a further embodiment, the periphery of the conical spiral blade 352 fits the inner wall of the processing cylinder 31, and both ends of the conical spiral blade 352 are fixedly connected with connecting plates 353, and the connecting plates 353 are sleeved and fixed on the periphery of the stirring shaft 351. The periphery of the stirring shaft 351 is fixedly connected with a spiral plate 356, and a blade 355 is fixedly connected between the spiral plate 356 and the conical spiral blade 352. The periphery of the conical spiral blade 352 is provided with equidistantly distributed notches 354, and the notches 354 are used for film fragments to pass through. The blade 355 is used to secondary crush the film fragments when the film fragments increase.

[0060] In this embodiment, when the driving motor 33 drives the stirring shaft 351 to rotate clockwise, the stirring shaft 351 will cause the conical spiral blades 352 to rotate synchronously through the connecting plate 353, so that the conical spiral blades 352 always push the incoming film fragments to the right, that is, close to one side of the linkage mechanism 4. Since the inner wall of the processing cylinder 31 is conical and gradually becomes smaller 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, thereby kneading more finely. In addition, as the number of film fragments increases, the blade 355 will also perform secondary crushing on the film fragments.

[0061] In a further embodiment, a driving motor 33 is installed above the recovery mechanism 1, and the output end of the driving motor 33 is engaged with one end of the stirring shaft 351. A cover end 34 is provided on the periphery of the processing cylinder 31, and the cover end 34 is used to seal the two ends of the processing cylinder 31. A connecting pipe 32 is provided at one end of the processing cylinder 31 close to the recovery mechanism 1, and the connecting pipe 32 is connected to the recovery 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 assembly 41.

[0062] In this embodiment, the cover end 34 is fixedly connected to the connecting pipe 42 on one side close to the linkage mechanism 4, and a support column is provided on the outside of the linkage mechanism 4; the collecting box 71 is through-connected from top to bottom, and a collecting bucket is provided at the bottom thereof, and the collecting bucket is connected to one end of the conveying pipe 8, and a blowing device is provided at the conveying pipe 8, so as to re-convey the unqualified film fragments collected in the collecting bucket to the inside of the crushing assembly 41.

[0063] In a further embodiment, a bracket 2 is provided on the outside of the recovery mechanism 1, and the bracket 2 is used to support the processing cylinder 31. The cover end 34 is fixedly connected to the top of the bracket 2, and a connecting pipe 42 is fixedly connected to one side of the cover end 34, and the connecting pipe 42 is fixedly connected to the bottom of the filter box 43.

[0064] In this embodiment, the recovery mechanism 1 is used for heat-capacity film fragments in the prior art and an additive can be added to the inside thereof; the crushing assembly 41 has a crushing roller inside and a motor for driving the crushing roller is installed on one side thereof.

[0065] The working principle of the present invention is as follows:

[0066] When the waste biodegradable film enters the crushing component 41, it can be crushed and enter 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 drives the driving motor 33 to drive the stirring shaft 351 to rotate clockwise to knead and crush the incoming film debris. Then, the connecting pipe 32 is opened to transport the material to the inside of the recycling mechanism 1 to add additives and heat-melt it for easy reuse;

[0067] When the film is crushed by the crushing assembly 41 and falls through the filter box 43, it will pass through the filter plate 592, thereby filtering so that the debris is more in line with the recovery size. After filtering for a certain period of time, the filter plate 592 will be blocked. At this time, the control device will drive the stepper motor 591 to operate, so that the rack 59 moves the filter plates 592 on both sides of the receiving frame 51 and the middle partition plate 53 to the left side of the filter box 43, so that the filter plate 592 originally on the outside enters the inside of the filter box 43, so that after one filter plate 592 is blocked, it is replaced with another unblocked filter plate 592, thereby continuously filtering the film fragments;

[0068] During the leftward movement of the receiving frame 51, the driving rack 64 is inserted into the insertion slot 52. When the filter plate 592 on the right side completely enters the filter box 43 for filtering, the control device will operate the electric cylinder 62 so that the receiving plate 63 moves to the right with the driving rack 64. At this time, the driving rack 64 will mesh with the linkage gear 593, so that the filter plate 592 rotates 160° counterclockwise, so that the filtering side of the filter plate 592 tilts downward, and during the rotation of the filter plate 592, it will contact and drive the linkage vertical plate 7 3 moves, when the filter plate 592 rotates to 160°, the linkage vertical plate 73 will contact the sensor 72, so as to give feedback to the control device to make the vibration motor 76 operate and generate vibration, thereby vibrating the filter plate 592 through the connecting rod 74 and the linkage vertical plate 73, and then the film residue remaining on the filter surface of the filter plate 592 will fall into the inside of the collection box 71 and then be transported back to the crushing assembly 41 by the conveying pipe 8 for re-crushing, so that the moved filter plate 592 can be cleaned, so as to facilitate the next replacement;

[0069] When the receiving frame 51 moves to the left and the middle partition plate 53 is at the through slot 44, the magnetic block 2 58 embedded in the inner side of the limiting plate 57 and the magnetic block 1 45 are repelled from each other by the magnetic force, so that the magnetic block 1 45 is pushed back by the magnetic force and moves to the right side, so that the left side of the magnetic block 1 45 no longer restricts one side of the filter plate 592, thereby facilitating the rotation of the filter plate 592, and at the same time, the right side of the magnetic block 1 45 begins to restrict the other filter plate 592;

[0070] When the driving motor 33 drives the stirring shaft 351 to rotate clockwise, the stirring shaft 351 will make the conical spiral blade 352 rotate synchronously through the connecting plate 353, so that the conical spiral blade 352 always pushes the incoming film fragments to the right (i.e., close to the side of the linkage mechanism 4). Since the inner wall of the processing cylinder 31 is conical and gradually becomes smaller 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, thereby kneading more finely. In addition, as the number of film fragments increases, the blade 355 will also perform secondary crushing on the film fragments.

[0071] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
