Description

Technical Field

[0001] The present invention relates to the field of waste recycling, and in particular to a waste processing device and method for plastic bag production. Background Art

[0002] Plastic bags are bags made of plastic as the main raw material. They are indispensable items in people's daily lives and are often used to hold other items.

[0003] In the process of plastic bag forming, some scraps are often produced due to cutting. These scraps are generally treated as waste. The existing plastic bag waste treatment generally involves collecting and packaging the waste first, and then melting a certain amount of plastic bag waste through a hot melt device and shaping it to make it into plastic particles again.

[0004] Since plastic bags are made of plastic film, the generated plastic bag waste is in the form of film sheets. When recycling existing waste, the waste is usually crushed and then compressed for collection. However, since the plastic bag waste is in the form of film sheets, when using a cutter to crush the plastic bag waste, the plastic bag waste will be entangled with the cutter, which not only affects the recycling efficiency of the plastic bag waste, but also causes damage to the cutter. However, when the plastic bag waste is directly conveyed to the compression mechanism, the plastic bag waste is fluffy, which will reduce the amount of compression at one time. Then, to compress a certain volume of plastic bag waste, multiple feeding and compression operations are required, which not only reduces the efficiency of waste recycling, but also leads to energy waste, and thus has certain defects.

[0064] (1) The present invention utilizes an integrated box, a compression assembly, and a feeding assembly in a coordinated manner. The feeding assembly includes a mounting shell and a kneading assembly. When the plastic bag waste enters the kneading assembly through the mounting shell, the first conveyor belt and the second conveyor belt rub the plastic bag waste on opposite sides and then transport it to the interior of the integrated box, thereby reducing the space occupied by the plastic bag waste entering the interior of the integrated box, thereby increasing the amount of plastic bag waste compressed by the compression assembly during one work, thereby reducing the frequency of the compression assembly working, and further reducing energy waste.

[0065] (2) The present invention utilizes a coordinated use of an installation shell, a kneading component, a tensioning component, and a heat dissipation component. When the kneading component is working, the tensioning component can ensure the tension of the first conveyor belt and the second conveyor belt, and can also detect the tension of the first conveyor belt and the second conveyor belt. When the kneading component is working, the heat dissipation component can dissipate heat for the first conveyor belt and the second conveyor belt, thereby reducing the probability of frictional heating and damage to the first conveyor belt and the second conveyor belt.

[0075] The present invention provides Figure 1-7 The waste processing device for plastic bag production shown in the figure includes an integrated box body 1, a compression component 2 and a feeding component 3. The integrated box body 1 includes a recovery box body 11 and a side panel 12. A feed hole corresponding to the feeding chamber 34 is opened on the top of the recovery box body 11. The side panel 12 is rotatably connected to one side of the recovery box body 11. A latch 13 is provided between the side panel 12 and the recovery box body 11. By pulling out the latch 13, the side panel 12 can be directly opened to take out the plastic bag waste compressed and recovered inside the recovery box body 11. The compression component 2 is arranged on the integrated box body 1. The compression component 2 is used to compress and recycle the plastic bag waste. The feeding component 3 is installed on the top of the integrated box body 1. The feeding component 3 is used to rub and feed the plastic bag waste, so that the feeding component 3 can transport the rubbed plastic bag waste through the feed hole to the interior of the recovery box body 11, so as to reduce the space occupied by the plastic bag waste entering the compression component 2, thereby improving the working efficiency of the compression component 2 in compressing the plastic bag waste.

[0076] Furthermore, the feeding assembly 3 includes a mounting shell 31, a partition 32, a kneading assembly 35, a tensioning assembly 36 and a heat dissipation assembly 37. The mounting shell 31 is fixedly mounted on the top of the integrated box 1. A guide frame 38 is fixedly mounted on the top of the inner cavity of the mounting shell 31. The guide frame 38 can guide the plastic bag waste to the feeding chamber 34, thereby preventing the plastic bag waste from entering the mounting chamber 33. The partition 32 is fixedly connected to the interior of the mounting shell 31. The interior of the mounting shell 31 is divided into two mounting chambers 33 and a feeding chamber 34 by two partitions 32. The material chamber 34 and the kneading component 35 are installed inside the mounting shell 31. The kneading component 35 uses the speed difference to knead and feed the plastic bag waste, so that the plastic bag waste is rolled into a stick shape, thereby reducing the space it occupies, so as to improve the efficiency of plastic bag waste recycling. The tensioning component 36 is installed inside the mounting chamber 33. The tensioning component 36 is used to adjust the tension of the kneading component 35, so as to ensure the working stability of the kneading component 35. The heat dissipation component 37 is arranged on the mounting shell 31, and the heat dissipation component 37 is used to dissipate heat for the kneading component 35.

[0077] Furthermore, the kneading assembly 35 includes a first conveyor belt 351, a second conveyor belt 352, a first main shaft 353, a second main shaft 354, a driven shaft 355, a connecting roller 356, a first guide roller 357 and a second guide roller 358. The first conveyor belt 351 and the second conveyor belt 352 are arranged inside the feeding chamber 34. The first conveyor belt 351 and the second conveyor belt 352 run in the same direction, that is, the opposite sides of the first conveyor belt 351 and the second conveyor belt 352 move in different directions. The first conveyor belt 351 moves upward toward one side of the second conveyor belt 352, and the second conveyor belt 352 moves downward toward one side of the first conveyor belt 351. The running speed of the second conveyor belt 352 is greater than the rotation speed of the first conveyor belt 351, so that when the plastic bag waste is located between the first conveyor belt 351 and the second conveyor belt 352, the first conveyor belt 351 and the second conveyor belt 352 can rub the plastic bag waste, and the plastic bag waste is conveyed downward on the first conveyor belt 351 and the second conveyor belt 352 until it is discharged into the interior of the recycling box 11. The first main shaft 353 and the second main shaft 354 are both rotatably installed in the interior of the installation shell 31, and the first main shaft 353 and the second main shaft 354 are respectively arranged in the interior of the first conveyor belt 351 and the second conveyor belt 352, and the driven shaft 355 is respectively The first conveyor belt 351 and the second conveyor belt 352 are arranged inside. A sliding hole matching the driven shaft 355 is provided at the bottom of one side of the partition 32. The tensioning assembly 36 acts on the driven shaft 355. The connecting roller 356 is respectively installed on the outside of the first main shaft 353, the second main shaft 354 and the driven shaft 355. The connecting roller 356 is respectively located inside the first conveyor belt 351 and the second conveyor belt 352. That is, two connecting rollers 356 are provided inside the first conveyor belt 351 and the second conveyor belt 352. The first guide roller 357 is rotatably installed inside the feeding chamber 34. The first guide roller 357 is respectively located on the first conveyor belt 351 and the second conveyor belt Inside the conveyor belt 352, a plurality of first guide rollers 357 can ensure the stability of the first conveyor belt 351 and the second conveyor belt 352 on the opposite side of the plastic bag waste, and when the first conveyor belt 351 and the second conveyor belt 352 are in the initial state, there is a certain gap between them, thereby avoiding the relative friction between the first conveyor belt 351 and the second conveyor belt 352. The second guide roller 358 is rotatably installed inside the feeding chamber 34. The second guide roller 358 is respectively located on the opposite side of the first conveyor belt 351 and the second conveyor belt 352. The second guide roller 358 can make the opposite side of the first conveyor belt 351 and the second conveyor belt 352 have the following characteristics: Figure 4 The recessed portion shown is for facilitating installation of a heat dissipation assembly 37 to dissipate heat for the first conveyor belt 351 and the second conveyor belt 352 .

[0078] In particular, the kneading component 35 also includes a servo motor 359, a first synchronous wheel 3510, a second synchronous wheel 3511 and a synchronous belt 3512. The servo motor 359 is installed on the front of the mounting housing 31. The servo motor 359 is connected to the second main shaft 354 in a transmission manner. The first synchronous wheel 3510 is fixedly installed at the end of the second main shaft 354. The second synchronous wheel 3511 is installed at the end of the first main shaft 353. The diameter of the second synchronous wheel 3511 is larger than the diameter of the first synchronous wheel 3510. The synchronous belt 3512 is sleeved on the outside of the first synchronous wheel 3510 and the second synchronous wheel 3511. Under the action of the step wheel 3510, the synchronous belt 3512 and the second synchronous wheel 3511, the first conveyor belt 351 and the second conveyor belt 352 can run in the same direction, and since the diameter of the second synchronous wheel 3511 is larger than the diameter of the first synchronous wheel 3510, the running speed of the first conveyor belt 351 is lower than the running speed of the second conveyor belt 352, thereby realizing the upward movement of the first conveyor belt 351 toward one side of the second conveyor belt 352, and the downward movement of the second conveyor belt 352 toward one side of the first conveyor belt 351, and the running speed of the second conveyor belt 352 is greater than the rotation speed of the first conveyor belt 351.

[0079] Furthermore, the tensioning assembly 36 includes a shaft seat 361, a limit plate 362, a limit spring 363, a guide rod 364, a limit block 365 and a pressure sensor 366. The shaft seat 361 is slidably arranged inside the installation chamber 33, and the end of the outer wall of the driven shaft 355 is rotatably connected to the shaft seat 361. The limit plate 362 is arranged inside the installation chamber 33, the limit plate 362 is located at the top of the shaft seat 361, and the limit spring 363 is arranged between the limit plate 362 and the shaft seat 361. The spring 363 can give the driven shaft 355 a downward elastic force through the shaft seat 361, so that the two driven shafts 355 give the first conveyor belt 351 and the second conveyor belt 352 a tension respectively, thereby ensuring the stability of the operation of the first conveyor belt 351 and the second conveyor belt 352. The top of the guide rod 364 is fixedly connected to the limit plate 362, and the outer wall of the guide rod 364 is slidably inserted and sleeved with the shaft seat 361. The limit spring 363 is slidably sleeved inside the guide rod 364, and the limit block 365 is fixed. Connected to the bottom of the guide rod 364, the pressure sensor 366 is installed at the bottom of the limit plate 362, and the top of the limit spring 363 is pressed and fitted with the pressure sensor 366. The pressure sensor 366 can detect the elastic force of the limit spring 363, so that the tension of the first conveyor belt 351 and the second conveyor belt 352 during operation can be reversely calculated, and then the tension threshold of the first conveyor belt 351 and the second conveyor belt 352 during operation can be set. Then, the value detected by the pressure sensor 366 can be compared with the tension threshold, not only to determine whether the first conveyor belt 351 and the second conveyor belt 352 are operating normally, but also to determine whether the first conveyor belt 351 and the second conveyor belt 352 are broken. Secondly, according to the change in the value range detected by the pressure sensor 366, the feeding speed of the first conveyor belt 351 and the second conveyor belt 352 can be controlled. That is, if the value range detected by the pressure sensor 366 changes greatly, the feeding speed is too fast and the feeding speed needs to be slowed down, otherwise the feeding speed needs to be accelerated.

[0080] Furthermore, the tensioning assembly 36 also includes an adjusting screw 367, a mounting seat 368, an adjusting shaft 369, a first reversing gear 3610, a second reversing gear 3611, and a locking nut 3612.

At the top of the outer wall, the first reversing gear 3610 is meshed with the second reversing gear 3611, thereby rotating the adjusting shaft 369. The adjusting shaft 369 can drive the adjusting screw 367 to rotate through the first reversing gear 3610 and the second reversing gear 3611, thereby changing the height of the limit plate 362, and then changing the elastic force of the limit spring 363 acting on the shaft seat 361. The locking nut 3612 is threadedly sleeved on the end of the outer wall of the adjusting shaft 369, and one side of the locking nut 3612 is squeezed and fit with the outer wall of the mounting shell 31. The locking nut 3612 can ensure the stability of the adjusting shaft 369 when it is prohibited.

[0081] Furthermore, the heat dissipation assembly 37 includes a mounting frame 371, a dust screen 372, a heat dissipation fan 373, a fixing plate 374, a positioning plate 375 and a positioning rod 376.

Under the action of the positioning rod 376 and the fixing plate 374, the stability of the installation of the fixing plate 374 and the cooling fan 373 can be guaranteed. When the mounting frame 371 is disassembled and the dust net 372 is cleaned, the cooling fan 373 can also be disassembled and maintained.

[0082] In particular, the compression assembly 2 includes a collection box 21, a lining 25, a push plate 22, a driving cylinder 23, a baffle 24 and a heating resistor 26. The collection box 21 is slidably sleeved on the inside of the recycling box 11, and one side of the collection box 21 is in contact with the side panel 12. The lining 25 is fixedly installed on the inside of the recycling box 11. The lining 25 corresponds to the collection box 21. Under the action of the lining 25, the push plate 22 can push the stick-shaped plastic bag waste entering the recycling box 11 directly to the inside of the collection box 21. The push plate 22 is slidably arranged on the inside of the lining 25. The driving cylinder 23 is installed on the other side of the recycling box 11.

The outer wall of the baffle 24 is connected to the collection box The box 21 slides and is interlaced. When the push plate 22 moves toward the collection box 21, the baffle 24 can block the stick-shaped plastic bag waste transported by the feeding component 3 to prevent the stick-shaped plastic bag waste from falling into the side of the push plate 22 away from the collection box 21. The heating resistance wire 26 is installed inside the recycling box body 11. The heating resistance wire 26 is used to heat the collection box 21. When the collection box 21 is full of plastic bag waste, the heating resistance wire 26 can heat the collection box 21 to shrink the plastic bag waste part inside the collection box 21, so that when the collection box 21 is taken out, the compressed plastic bag waste is prevented from being deformed again and becoming fluffy and messy. The heating temperature condition of the heating resistance wire 26 for the collection box 21 is 80℃-100℃, and the duration is 30-60 seconds.

[0083] Another object of the present invention is to provide a method for treating waste from plastic bag production, comprising the following specific steps:

[0084] Step 1: When recycling plastic bag waste, the driving cylinder 23 drives the push plate 22 to be located on the side of the inner cavity of the recycling box 11 away from the collection box 21, and the servo motor 359 drives the second main shaft 354 to rotate counterclockwise. The second main shaft 354 drives the first main shaft 353 to rotate counterclockwise through the first synchronous wheel 3510, the synchronous belt 3512, and the second synchronous wheel 3511, so that the first main shaft 353 and the second main shaft 354 drive the first conveyor belt 351 and the second conveyor belt 352 to rotate counterclockwise. Under the action of the first synchronous wheel 3510, the synchronous belt 3512, and the second synchronous wheel 3511, the rotation speed of the second conveyor belt 352 is greater than the rotation speed of the first conveyor belt 351.

[0085] Step 2: When the plastic bag waste passes through the guide frame 38 and enters between the first conveyor belt 351 and the second conveyor belt 352, the first conveyor belt 351 and the second conveyor belt 352 knead the plastic bag waste into a stick shape, and the rotation speed of the second conveyor belt 352 is greater than the rotation speed of the first conveyor belt 351, and the stick-shaped plastic bag waste is discharged from between the second conveyor belt 352 and the first conveyor belt 351 into the interior of the recycling box 11. When a certain amount of stick-shaped plastic bag waste is accumulated inside the recycling box 11, the driving cylinder 23 drives the pushing plate 22 to move toward the collection box 21, so that the stick-shaped plastic bag waste inside the recycling box 11 is pushed into the interior of the collection box 21, and then the driving cylinder 23 drives the pushing plate 22 to be located on the side of the inner cavity of the recycling box 11 away from the collection box 21, and the above feeding steps are repeated;

[0086] Step 3: When the collection box 21 is full of plastic bag waste, the heating resistance wire 26 heats the plastic bag waste inside the collection box 21, so that the plastic bag waste inside the collection box 21 is in a sticky state, and then the pin 13 is pulled out, the side panel 12 is opened, the collection box 21 is taken out, and the plastic bag waste inside the collection box 21 is taken out and stored.
