Description

Technical Field

[0001] This invention relates to the field of plastic waste recycling technology, specifically to a crushing and recycling equipment for construction template waste. Background Technology

[0002] Aluminum composite panels (ACPs) are a commonly used new type of building decoration material, widely used in building exterior walls, interior walls, and ceiling decoration. Structurally, ACPs are generally rectangular, consisting of two aluminum sheets bonded together with a high-molecular-weight polyethylene core to form a panel structure. During use, dents or deformation of ACPs can affect their aesthetics; therefore, deformed ACPs are generally recycled.

[0003] There are three main methods for separating aluminum composite panels: fire separation, chemical separation, and dry physical separation. Fire separation involves heating the surface of the aluminum composite panel with an open flame in a coal stove to soften it before tearing it apart. The entire process takes about 1 hour and poses safety hazards. Chemical separation involves immersing the aluminum composite material in a separating agent at room temperature for 2-3 hours before the aluminum and plastic can separate. Dry physical separation uses an aluminum-plastic separator to break the aluminum composite panel into pieces and uses the density difference between aluminum and plastic to separate them using airflow.

[0004] The existing dry physical separation method requires a separation process after the aluminum and plastic layers of the aluminum composite panel are crushed as a whole, and the efficiency and effect of the separation need to be improved.

[0005] The information disclosed in the background section is only intended to enhance the understanding of the background of this disclosure, and therefore may include information that does not constitute prior art known to those skilled in the art. Summary of the Invention

[0006] The purpose of this invention is to design a method that only crushes and removes the plastic layer in the part of the aluminum composite panel that is in contact with the aluminum layer, without crushing and removing the aluminum layer, and then performs air separation, thereby reducing the number of processes and improving the separation effect, avoiding mixing and then separating, and thus solving the above-mentioned shortcomings in the technology.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a construction template waste crushing and recycling processing equipment for separating the two aluminum layers and the plastic layer of an aluminum composite panel, comprising a frame, a conveying assembly installed inside the frame, and two cutting rollers rotating in opposite directions rotatably inside the frame, the cutting rollers rotating from the plastic layer to the aluminum layer towards the conveying assembly. Each of the two cutting rollers has a pressing plate on its opposite side, and a pressing assembly is installed on the frame to apply a spring force to the pressing plates towards the cutting rollers. The two cutting rollers are positioned between the two aluminum layers on a horizontal plane.

[0008] The plastic layer is crushed by two cutting rollers rotating in opposite directions, and the two aluminum layers are inserted between the pressing plate and the cutting rollers respectively. The cutting rollers are brought into contact with the inner wall surface of the aluminum layer and crush the part in contact with the plastic layer. At the same time, the aluminum layer is driven to move along the forward direction of the conveying assembly by rolling friction.

[0009] Preferably, the central axes of the two cutting rollers are on the same plane and parallel, with one cutting roller located directly above the other.

[0010] Preferably, a cutter is fixedly mounted on the frame between the two cutting rollers, with the cutting edge of the cutter facing horizontally toward the conveying assembly and located between the cutting rollers and the conveying assembly, and the cutter not contacting the cutting rollers.

[0011] Preferably, the compression assembly includes a guide rod that passes through the frame and is slidably connected to the frame, a stop block installed at the end of the guide rod away from the pressing plate, and a spring fixedly installed between the frame and the pressing plate, with the end of the guide rod away from the stop block fixedly connected to the pressing plate.

[0012] Preferably, when the stop block is in contact with the surface of the frame, the distance between the pressing plate and the cutting roller is less than the thickness of the aluminum layer.

[0013] Preferably, the conveying assembly includes a plurality of conveying rollers rotatably mounted on a frame, a conveyor belt that is rolled together on the plurality of conveying rollers, a drive gear fixedly mounted at the end of the conveying roller closest to the cutting roller, a push roller disposed at the top of the conveying roller closest to the cutting roller, and a first driven gear fixedly mounted at the end of the push roller, the first driven gear meshing with the drive gear.

[0014] Preferably, a second driven gear is fixedly installed at the ends of both cutting rollers, and the two second driven gears mesh with each other. A third driven gear is rotatably installed on the frame, and one of the second driven gears and the driving gear mesh with the third driven gear.

[0015] Preferably, the pressing plate has an arc surface on the side near the cutting roller, and the pressing plate has rounded corners on the side near the cutting roller and the side near the conveying assembly.

[0016] Preferably, an input wheel is also fixedly installed at the end of the conveying roller on which the first driven tooth is mounted.

[0017] The technical effects and advantages provided by the present invention in the above technical solution are as follows:

[0018] 1. This invention uses the cooperation of cutting rollers, cutters, pressing components and conveying components to crush and remove the plastic layer in the part of the aluminum composite panel that is in contact with the aluminum layer, without crushing and removing the aluminum layer. Compared with the prior art, which crushes the aluminum layer and the plastic layer as a whole at the same time and then separates them by air, the separation effect is better and there will be no situation where plastic particles are mixed in with aluminum particles. It is easy to classify and recycle aluminum and plastic.

[0019] 2. The present invention can directly obtain two parts, aluminum layer and plastic particles, by directly crushing and removing the plastic layer in the part of aluminum composite panel that is in contact with aluminum layer. At the same time, the separation efficiency is high, and there is no need to use equipment to carry out the separation process as in the prior art. The aluminum layer can be directly removed from the plastic particles.

[0020] 3. At the same time, the present invention can be applied to aluminum composite panels of different thicknesses. As long as the farthest distance between the outer circumferences of the two cutting rollers is less than the distance between the two aluminum layers, the part of the two aluminum layers that is in contact with the plastic layer can be crushed and removed, and there will be no situation where a thin layer of plastic layer remains on the aluminum layer.

Detailed Implementation

[0029] To enable those skilled in the art to better understand the technical solutions in this application, the technical solutions in the embodiments of this application will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0030] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0031] This invention provides, for example Figure 1-5The equipment shown is a construction template waste crushing and recycling processing device used to separate the two aluminum layers 1a and plastic layers 1b of an aluminum composite panel 1. It includes a frame 2, on which multiple arrayed conveyor rollers 3a are rotatably mounted. A conveyor belt 3b is connected to the multiple conveyor rollers 3a in a common rolling manner. The end of the outermost conveyor roller 3a passes through the frame 2 and is fixedly mounted with a drive gear 3c and an input wheel 10. A push roller 3d is provided at the top of the conveyor roller 3a with the drive gear 3c fixedly mounted. The push roller 3d is rotatably connected to the frame 2 and one end passes through the frame 2. A first driven gear 3e is fixedly mounted at the end of the push roller 3d passing through the frame 2. The driving gear 3e and the driving gear 3c mesh. The conveying roller 3a, the conveyor belt 3b, the driving gear 3c, the pushing roller 3d, and the first driven gear 3e constitute the conveying assembly 3 for conveying the aluminum-plastic composite sheet 1. When the aluminum-plastic composite sheet 1 moves on the conveyor belt 3b to below the pushing roller 3d, it contacts the surface of the pushing roller 3d. At this time, the pushing roller 3d applies a lateral force to the aluminum-plastic composite sheet 1 through rolling friction with the top surface of the aluminum-plastic composite sheet 1. Two vertically distributed cutting rollers 4 are rotatably mounted on the frame 2. The central axes of the two cutting rollers 4 are parallel to each other on the same horizontal plane. The ends of the two cutting rollers 4 are fixedly connected to a second driven gear 8. To ensure that the driving gear 3c can synchronously drive the two cutting rollers 4 to rotate in opposite directions when they mesh with each other, a third driven gear 9 is mounted on the frame 2. One of the second driven gears 8 and the driving gear 3c meshes with the third driven gear 9. Here, the transmission ratio between the driving gear 3c and the second driven gear 8 is large, ensuring that the external power source drives the input wheel 10 to rotate. When the input wheel 10 drives the conveyor roller 3a to rotate one revolution, the cutting roller 4 rotates multiple revolutions, maintaining high-speed cutting. A cutter 7 is fixedly mounted on the frame 2 between the two cutting rollers 4, located near the conveyor assembly. On one side of component 3, and with the blade of cutter 7 horizontally facing conveying component 3, when push roller 3d pushes aluminum-plastic board 1 to contact cutter 7 through friction, plastic layer 1b on aluminum-plastic board 1 contacts cutter 7, and cutter 7 cuts plastic layer 1b into upper and lower parts. Plastic layer 1b moves along cutter 7 toward cutting roller 4. When plastic layer 1b contacts cutting roller 4, since the rotation direction of cutting roller 4 is towards conveying component 3 from plastic layer 1b to aluminum layer 1a, cutting roller 4 will push plastic layer 1b toward aluminum layer 1a. Therefore, the upper and lower parts of aluminum-plastic board 1 that are cut will expand outward, and when cutting roller 4 contacts plastic layer 1b, it will crush plastic layer 1b.To ensure that the cutting roller 4 cleanly crushes the portion of the plastic layer 1b that contacts the aluminum layer 1a, we need to ensure that the cutting roller 4 contacts the inner wall of the aluminum layer 1a. For this purpose, a guide rod 6a is installed through and slidably on the frame 2. A stop block 6b is fixedly installed at one end of the guide rod 6a, and a pressing plate 5 is fixedly installed at the other end. A spring 6c is fixedly installed between the pressing plate 5 and the inner wall of the frame 2. The guide rod 6a, the stop block 6b, and the spring 6c constitute a pressure assembly 6 that pushes the pressing plate 5 to apply pressure to the cutting roller 4. The spring 6c pushes the pressing plate 5 to contact the aluminum layer 1a, thereby bringing the aluminum layer 1a and the plastic layer 1b into contact with the cutting roller 4, ensuring that the surface of the aluminum layer 1a contacts the surface of the cutting roller 4. To ensure the service life of the cutting roller 4 and reduce the wear and tear of the aluminum layer 1a, the hardness of the cutting roller 4 can be greater than that of the plastic layer 1b but less than that of the aluminum layer 1a, which can also reduce the elastic force of the spring 6c. When the stop block 6b contacts the surface of the frame 2, the distance between the pressing plate 5 and the cutting roller 4 should be less than the thickness of the aluminum layer 1a, so that the spring 6c can apply pressure to the aluminum layer 1a, and at the same time avoid the pressing plate 5 and the cutting roller 4 from contacting and rubbing. In order for the aluminum-plastic sheet 1 to enter better between the pressing plate 5 and the cutting roller 4 when cutting, the side of the pressing plate 5 near the cutting roller 4 is arc-shaped, and the side of the pressing plate 5 near the cutting roller 4 and near the conveying component 3 has rounded corners.

[0032] The overall workflow of the equipment is as follows: An external power source drives the input wheel 10 to rotate, which in turn drives the conveyor roller 3a to rotate. The conveyor roller 3a drives the transmission belt and the drive gear 3c. The transmission belt drives the aluminum-plastic sheet 1 gradually towards the push roller 3d. The drive gear 3c drives the first driven gear 3e to rotate, which in turn drives the push roller 3d and the third driven gear 9 to rotate. The third driven gear 9 drives the second driven gear 8 to rotate. The two driven gears mesh with each other, driving the two cutting rollers 4 to rotate at high speed in opposite directions. When the aluminum-plastic sheet 1 on the transmission belt contacts the push roller 3d, the push roller 3d will push the aluminum-plastic sheet 1 to contact the cutter 7 through rolling friction. The cutter 7 will horizontally cut the plastic layer 1b in the middle of the aluminum-plastic sheet 1 into upper and lower sections. In some parts, the aluminum layer 1a will come into contact with the pressing plate 5. When the upper and lower parts of the aluminum-plastic panel 1 move between the cutting roller 4 and the pressing plate 5, the spring 6c will apply a pushing force to the pressing plate 5 through its elasticity, pushing the aluminum layer 1a towards the cutting roller 4, so that the cutting roller 4 comes into contact with the inner wall of the aluminum layer 1a. When the cutting roller 4 rotates at high speed, it will crush and cut off the plastic layer 1b in contact with the aluminum layer 1a. Therefore, it is necessary to ensure that the farthest distance between the outer circumferences of the two cutting rollers 4 is less than the distance between the two aluminum layers 1a, so as to avoid the situation where a thin layer of plastic layer 1b remains on the aluminum layer 1a. At the same time, the cutting roller 4 will also generate rolling friction when it comes into contact with the aluminum layer 1a, so that when the pushing roller 3d does not apply a pushing force to the aluminum-plastic panel 1, it will drive the aluminum layer 1a to move out from between the pressing plate 5 and the cutting roller 4.

[0033] It is important to note that the constructions and arrangements of this application shown in several different exemplary embodiments are merely illustrative. Although only a few embodiments are described in detail in this disclosure, those who consult this disclosure will readily understand that many modifications are possible (e.g., changes in the size, dimensions, structure, shape and proportion of various elements, as well as parameter values ​​(e.g., temperature, pressure, etc.), installation arrangements, use of materials, color, orientation, etc.) without substantially departing from the novel teachings and advantages of the subject matter described in this application.
