Abstract

This invention discloses an energy-saving cleaning device for recycling waste plastics, belonging to the field of plastic recycling technology. It includes a first cylinder and a second cylinder. A feed hopper is installed at one end of the first cylinder, and a friction roller is installed inside the first cylinder. In this invention, a spray assembly is installed inside.

Description

Technical Field

[0001] This invention belongs to the field of plastic recycling technology, and in particular relates to an energy-saving cleaning device for recycling waste plastics. Background Technology

[0002] Plastic bottles are ubiquitous in daily life, including mineral water bottles, beverage bottles, and various liquid packaging bottles. After use, they can be recycled to reduce resource waste. When recycling plastic bottles, labels and other markings on the outer surface are removed and the bottles are cleaned to reduce impurities in the plastic and improve the quality of recycled plastic.

[0003] During the process of removing and cleaning labels from the outer wall of plastic bottles, adhesives such as self-adhesive are used to fix the labels to the bottle body. Some labels are completely fixed by adhesives. Therefore, when removing the labels, some adhesive and labels may remain on the bottle surface, which is difficult to clean by rubbing alone. This can affect the overall quality of the plastic bottle in subsequent processing. Summary of the Invention

[0004] The purpose of this invention is to solve the problem of adhesive residue caused by the adhesive used to fix the labels on the surface of plastic bottles during the recycling process, which occurs when cleaning the labels by friction alone.

[0037] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0038] 1. In this invention, by incorporating a spray assembly, the label on the surface of the plastic bottle can be peeled off by friction rollers and friction teeth during the recycling and cleaning process. During the peeling process, a desiccant is sprayed by a sprayer, and the sliding plate moves along a linkage connecting rod to cause the sprayer to swing, thereby increasing the spray coverage area. This allows for the complete cleaning of the label and adhesive residue on the surface of the plastic bottle through physical friction and chemical dissolution, solving the problem of adhesive residue residue in conventional cleaning. At the same time, the movement of the sliding plate can use the pushing teeth to directionally push the peeled label and adhesive debris to be discharged from one end of the collection tank, avoiding the accumulation of debris in the second cylinder and the generation of secondary pollution.

[0039] 2. In this invention, by incorporating an isolation component, the design allows airflow to enter through the air inlet when the suction module extracts the label peeled from the inside of the first cylinder, reducing the airflow drawn from the inside of the second cylinder. Simultaneously, the isolation cover prevents the adhesive remover sprayed from the sprayer inside the second cylinder from affecting the suction effect of the suction module. Furthermore, the lever allows the plastic bottle inside the connecting cylinder to be pushed into the second cylinder through the gap between the isolation cover and the connecting cylinder. Because the connecting sleeve contains a spring, the isolation cover can flip when there are too many plastic bottles to ensure they can pass through smoothly, preventing blockage. A limiting rod prevents the isolation cover from flipping into the first cylinder and losing its isolation effect.

[0040] 3. In this invention, by providing a feeding component, the plastic bottle can be sheared by the shearing wheel to reduce its volume when it is fed in, and the plastic bottle can be squeezed by the extrusion wheel to prevent the plastic bottle from rebounding when it rubs against the friction roller and friction teeth, which would affect the label removal effect. Furthermore, the flattening of the plastic bottle can prevent liquid from entering the bottle body and thus avoid wasting the desiccant. Attached Figure Description

Detailed Implementation

[0051] 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.

[0052] Please see Figures 1-8This invention provides a technical solution: an energy-saving cleaning device for recycling waste plastics, comprising a first cylinder 4 and a second cylinder 10. A feed hopper 3 is installed at one end of the first cylinder 4, and a drive motor 1 is installed on one side of the feed hopper 3. A friction roller 12 is provided inside the first cylinder 4, with one end of the friction roller 12 fixedly connected to the output shaft of the drive motor 1, and the other end of the friction roller 12 located inside the second cylinder 10. Friction teeth 13 are installed on the inner walls of both the first cylinder 4 and the second cylinder 10. The device also includes:

[0053] Please see Figure 5 , Figure 6 , Figure 7 The spray assembly 9 includes a mounting base 911 installed on the inner wall of the second cylinder 10. A sprayer 913 is rotatably mounted on one end of the mounting base 911. Both ends of the sprayer 913 are connected to connecting pipes 912, and the connecting pipes 912 pass through the through holes provided in the mounting base 911.

[0054] The lever 914 is installed on the outer wall of the connecting pipe 912 and is located on one side of the mounting base 911. The lever 914 is slidably connected to the second cylinder 10 through the internal groove of the second cylinder 10.

[0055] The spray assembly 9 also includes a sheath 902, which is disposed on the outer wall of the second cylinder 10, and one end of the sheath 902 is provided with a groove corresponding to the lever 914.

[0056] The connecting rod 901 is slidably disposed inside the sheath 902, and one end of the connecting rod 901 is slidably connected to the sliding groove provided inside the lever 914, and one side of the connecting rod 901 is in contact with the outer wall of the second cylinder 10.

[0057] The fixing plate 905 is installed at the bottom opening of the second cylinder 10, and the fixing plate 905 is a mesh plate with fixing teeth 908 installed on its surface.

[0058] The spray assembly 9 also includes: a slide plate 904, which is slidably installed in a groove inside the fixed plate 905. Push teeth 903 are installed on the surface of the slide plate 904, and the push teeth 903 correspond to the fixed teeth 908.

[0059] The baffle 909 is installed on both sides of the fixing plate 905, and the baffle 909 corresponds to the fixing tooth 908, and the top of the baffle 909 has a semi-circular dome.

[0060] Push block 915 is installed on the bottom surface of slide plate 904, and the bottom end of connecting rod 901 is provided with an inclined block corresponding to the inclined surface of push block 915;

[0061] The spray assembly 9 also includes: a collection trough 907, which is installed at the bottom opening of the second cylinder 10 and corresponds to the fixing plate 905. A grid 910 is provided at one end of the collection trough 907 and the grid 910 is located on the bottom surface of the slide plate 904. Notches corresponding to the connecting rod 901 are provided on both sides of the collection trough 907.

[0062] An electric push rod 906 is installed at one end of a collection trough 907, and the telescopic end of the electric push rod 906 passes through the collection trough 907 and is fixedly connected to the slide plate 904.

[0063] Furthermore, the outer wall of the first cylinder 4 is provided with an air extraction module 7, the other end of the second cylinder 10 is provided with a discharge pipe 11, the outer wall of the feed hopper 3 is provided with a bracket 2, the bottom ends of the first cylinder 4 and the second cylinder 10 are both provided with a support 5, a drive motor 1 is provided on one side of the feed hopper 3, and one end of the friction roller 12 is fixedly connected to the output shaft of the drive motor 1.

[0064] Specifically: When removing the label from the surface of the plastic bottle, as the plastic bottle enters the first cylinder 4, the drive motor 1 drives the friction roller 12 to rotate, so that the friction roller 12 and the friction teeth 13 rub the label on the surface of the plastic bottle to remove the label. At the same time, the removed label can be extracted by the air extraction module 7.

[0065] Furthermore, as the friction roller 12 rotates, the plastic bottle gradually enters the second cylinder 10. A desiccant is sprayed onto the surface of the plastic bottle via the connecting pipe 912 and the sprayer 913, facilitating the removal of the adhesive label from the plastic bottle surface by the friction roller 12 and friction teeth 13. The electric push rod 906 pushes the sliding plate 904 to move, thereby moving the push block 915. Since one end of the connecting rod 901 has a corresponding inclined block to the push block 915, the push block 915 compresses the connecting rod 901 during its movement, pushing it to move within the sheath 902. Simultaneously, since the other end of the connecting rod 901 is slidably connected to the internal groove of the lever 914, the movement of the connecting rod 901 causes the lever 914 to swing, thereby rotating the connecting pipe 912 and the sprayer 913, thus improving the spraying effect.

[0066] Furthermore, as the adhesive remover and other agents are sprayed, they flow down the inner wall of the second cylinder 10, washing away label fragments from the inner wall of the second cylinder 10 so that they fall onto the surfaces of the fixing plate 905 and the sliding plate 904. Since the fixing plate 905 is a mesh plate, the liquid can flow into the collection tank 907 and be discharged from the other end of the collection tank 907. At this time, the fragments accumulate on the surfaces of the fixing plate 905 and the sliding plate 904. As the electric push rod 906 drives the sliding plate 904 to move, it can push the fixing plate 905 through the push teeth 903. Debris on the surfaces of the fixed plate 905 and the slide plate 904 approaches the fixed teeth 908 and passes through the gap between the fixed teeth 908. When the electric push rod 906 drives the slide plate 904 to move back, the fixed teeth 908 are in a contracted state, so less debris flows back with the slide plate 904. As the slide plate 904 moves back and forth repeatedly, the debris can be moved to one end by the interaction between the push tooth 903 and the fixed tooth 908 and fall from the grid 910 into the outlet of the collection tank 907 for direct discharge.

[0067] Please see Figure 4 The isolation component 8 includes a connecting cylinder 801 disposed between the first cylinder 4 and the second cylinder 10. An air inlet 803 is provided inside the connecting cylinder 801, and an air inlet cover 802 is installed on the outer wall of the connecting cylinder 801, with the air inlet cover 802 corresponding to the air inlet 803.

[0068] The mounting cylinder 808 is installed on the outer wall of the friction roller 12 and is located inside the connecting cylinder 801. The outer wall of the mounting cylinder 808 is provided with an air guide groove 807.

[0069] The isolation assembly 8 also includes: an isolation cover 805, which is installed on the outer wall of the mounting cylinder 808 and has a gap between the isolation cover 805 and the connecting cylinder 801, and a connecting sleeve 804 is provided on the surface of the isolation cover 805;

[0070] Spring 809 is installed on the outer wall of mounting cylinder 808, and multiple springs 809 are arranged circumferentially, and springs 809 are located inside connecting sleeve 804;

[0071] The isolation assembly 8 also includes: a limiting rod 810, which is installed on the outer wall of the mounting cylinder 808, and the limiting rod 810 and the spring 809 are placed alternately, and the limiting rod 810 is located on one side of the isolation cover 805;

[0072] A lever 806 is installed on the outer wall of the mounting cylinder 808, and one end of the lever 806 is an arc-shaped rod that fits against the inner wall of the connecting cylinder 801, and the other end of the arc-shaped rod is located in the gap between the isolation cover 805 and the connecting cylinder 801.

[0073] Specifically: When collecting the peeled label fragments inside the first cylinder 4 through the suction module 7, as the suction module 7 drives the airflow, external gas can enter the first cylinder 4 through the air inlet 803 to reduce the amount of airflow from the second cylinder 10. The incoming airflow can be blown into the first cylinder 4 under the influence of the air guide groove 807 on the outer wall of the mounting cylinder 808, so as to ensure that the peeled labels can smoothly enter the suction module 7 for discharge. At the same time, the isolation cover 805 can isolate the second cylinder 10 from the first cylinder 4 to further reduce the airflow inside the second cylinder 10 from entering the first cylinder 4 and prevent the desiccant sprayed inside the second cylinder 10 from entering the first cylinder 4 and causing an impact.

[0074] Furthermore, during the process of the friction roller 12 and friction teeth 13 peeling off the label on the surface of the plastic bottle inside the first cylinder 4, the plastic bottle will gradually move into the second cylinder 10. When it moves into the connecting cylinder 801, since the actuating rod 806 is installed on the outer wall of the mounting cylinder 808, the rotation of the friction roller 12 and the mounting cylinder 808 can drive the actuating rod 806 to rotate. Since one end of the actuating rod 806 is an arc-shaped rod that fits against the inner wall of the connecting cylinder 801, the plastic bottle can be pushed by the actuating rod 806 during the rotation, so that the plastic bottle passes through the isolation cover 805. During the passage, since the connecting sleeve 804 is provided with a spring 809, the isolation cover 805 can be bent when there are too many plastic bottles, so as to ensure that the plastic bottle can smoothly enter the second cylinder 10.

[0075] Please see Figure 8 Feeding assembly 6, including a feeding hopper 602 installed above the feeding hopper 3, and a baffle 601 installed on the inner wall of the feeding hopper 602;

[0076] The sliding frame 603 is slidably disposed on the surface of the baffle 601, and the sliding frame 603 is in the shape of a grid plate. A moving module 604 is installed at one end of the sliding frame 603, and the moving module 604 is installed on one side of the hopper 602.

[0077] The feeding assembly 6 also includes a shearing wheel 605, which is rotatably installed inside the feeding hopper 602, and the shearing wheels 605 are arranged in pairs;

[0078] The first drive module 606 is disposed on the outer wall of the hopper 602, and the output end of the first drive module 606 is connected to the shearing wheel 605.

[0079] The feeding assembly 6 also includes: an extrusion wheel 607, which is rotatably mounted inside the feeding hopper 602 and is located below the shearing wheel 605, and the extrusion wheels 607 are arranged in pairs;

[0080] The second drive module 608 is installed on the outer wall of the hopper 602, and the output end of the second drive module 608 is fixedly connected to the shaft of the extrusion wheel 607.

[0081] Furthermore, both the first drive module 606 and the second drive module 608 include corresponding drive devices and transmission structures.

[0082] Specifically: When feeding into the feed hopper 3, plastic bottles can be placed into the discharge hopper 602, and under the action of the baffle 601, the plastic bottles can fall between the shearing rollers 605. At the same time, the first drive module 606 drives the shearing rollers 605 to rotate to shear the plastic bottles and reduce their volume. As the plastic bottles fall further, the second drive module 608 drives the extrusion rollers 607 to rotate to extrude the plastic bottles, thereby flattening them. This prevents the plastic bottles from retracting when the friction rollers 12 and friction teeth 13 peel off the labels, which would affect the peeling effect. Also, because the plastic bottles are flattened, liquids such as desiccant are less likely to enter the plastic bottles and cause waste.

[0083] Furthermore, after the plastic bottle is placed into the hopper 602, the sliding frame 603 can be moved by the moving module 604 to move the plastic bottle inside the hopper 602, thereby pushing the vertically positioned plastic bottle over so that the shearing wheel 605 can cut it.

[0084] The above are merely preferred embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
