Description

Technical Field

[0002] Continuous fiber reinforced thermoplastic resin composite sheets are widely used, replacing fiberglass and metal sheets in areas such as vans and containers, and these sheets are recyclable. However, the current main recycling method involves multiple crushing processes using a pulverizer. During crushing, due to the uncontrollable shearing method, the particle size uniformity is poor, and the internal continuous fibers are stretched, resulting in a larger length dispersion range. This leads to significant performance fluctuations in the recycled material during subsequent use, and the crushing process generates considerable dust and residue pollution, which has a certain impact on the health of workers.

[0069] This utility model provides a recycling system for sheet metal.

[0070] Please see Figure 1A sheet material recycling system 100 is used to process sheet material 200. The sheet material recycling system 100 includes a frame 110, a placement platform 120, at least one first cutting member 131, a second cutting member 151, and at least two drive rollers 140. The placement platform 120 is disposed on the frame 110 and is used to place the sheet material 200 to be processed. The first cutting member 131 is disposed on the frame 110 and located above the placement platform 120. The first cutting member 131 is pivotally connected to the frame 110 about a first axis extending along a first horizontal direction D1. The second cutting member 151 is disposed on the frame 110 and located above the placement platform 120. The second cutting member 151 is disposed along the first horizontal direction D1 and is movably connected to the frame 110 along a vertical direction DH. The drive rollers 140 are disposed on the frame 110 and located above the placement platform 120, and the axis of the drive rollers 140 extends along the first horizontal direction D1. The drive roller 140 is pivotally connected to the frame 110 about its axis. At least two drive rollers 140 are spaced apart along a second horizontal direction D2, which is perpendicular to the first horizontal direction D1. It should be noted that along the second horizontal direction D2 (or the direction of travel of the sheet 200), the second cutting member 151 is located downstream of the first cutting member 131, at least one drive roller 140 is located upstream of the first cutting member 131, and at least one drive roller 140 is located between the first cutting member 131 and the second cutting member 151.

[0071] Please continue reading. Figure 1 The sheet recycling system 100 also includes a first pivot shaft 132, which is disposed on the frame 110 and above the placement platform 120. The first pivot shaft 132 is disposed along a first horizontal direction D1 and is pivotally connected to the frame 110 about the aforementioned first axis. Furthermore, a first cutting member 131 is disposed on the outer periphery of the first pivot shaft 132 and is rotatable with the first pivot shaft 132. The number of first cutting members 131 at a single first pivot shaft 132 is at least two, and these at least two first cutting members 131 are spaced apart along the first horizontal direction D1. One end of the first pivot shaft 132 is connected to a first drive member 133, which is disposed on the frame 110 and is used to drive the first pivot shaft 132 to rotate. The first drive member 133 is, for example, constructed as a motor.

[0072] Optionally, the first cutting member 131 is configured to be adjustably connected to the first pivot shaft 132 along a first horizontal direction D1. See now. Figure 1 and Figure 2The first cutting member 131 is disposed on the outer periphery of the first pivot shaft 132, and a plurality of first cutting members 131 are spaced apart along the first horizontal direction D1. The first pivot shaft 132 has a mounting surface 134, which is configured, for example, as a plane perpendicular to the vertical direction DH. The sheet metal recycling system 100 also includes positioning members 135 and fasteners 136. The positioning member 135 is disposed on the mounting surface 134, and the fasteners 136 are connected to the positioning member 135 and the first pivot shaft 132, so that the positioning member 135 is fixed to the first pivot shaft 132. Specifically, along the first horizontal direction D1, positioning members 135 are disposed on both sides of any one first cutting member 131. In other words, a single first cutting member 131 is held by two positioning members 135, so that the position of the first cutting member 131 relative to the first pivot shaft 132 is defined. It is understood that the positioning member 135 and the first pivot shaft 132 have corresponding mounting holes, and the fastener 136 is connected to these mounting holes. By adjusting and fixing the position of the first cutting member 131 relative to the first pivot shaft 132, the position of the first cutting member 131 on the first pivot shaft 132 is changed, thereby adjusting two adjacent first cutting members 131 along the first horizontal direction D1. Preferably, multiple first cutting members 131 are equidistantly arranged along the first horizontal direction D1. That is, multiple equidistantly arranged first cutting members 131 can cut the sheet 200 into multiple strips of equal width.

[0073] Please see now Figure 1 The transmission pressure roller 140 includes a roller body 141 and a second pivot shaft 142. The second pivot shaft 142 is pivotally connected to the frame 110. The roller body 141 is disposed on the outer periphery of the second pivot shaft 142 and can rotate with the second pivot shaft 142. It should be noted that when the sheet material 200 is placed on the placement platform 120, the outer periphery of the roller body 141 is used to abut against the upper surface of the sheet material 200 to be processed. It is readily apparent that the first cutting member 131 acts on the upper surface of the sheet material 200 to cut the sheet material 200 into strip structures. It can be understood that the second pivot shaft 142 is disposed along a first horizontal direction D1 (or, the axis of the second pivot shaft 142 extends along the first horizontal direction D1). Furthermore, one end of the second pivot shaft 142 is connected to a second driving member 143, which is disposed on the frame 110. The second driving member 143 is used to drive the second pivot shaft 142 to rotate. The second drive component 143 is, for example, constructed as a motor.

[0074] Please continue reading. Figure 1To enable the second cutting member 151 to move vertically DH, the sheet material recycling system 100 further includes at least one lifting member 152. Specifically, the lifting member 152 is disposed on the frame 110 and located above the second cutting member 151. The lifting member 152 is disposed vertically DH and its two ends are respectively connected to the frame 110 and the second cutting member 151. The lifting member 152 is used to drive the second cutting member 151 to move vertically DH. It is understood that the lifting member 152 can be constructed as an electric cylinder, pneumatic cylinder, hydraulic cylinder, etc. The second cutting member 151 is used to cut the strip-shaped sheet material 200 (after being cut by the first cutting member 131) again. In other words, the second cutting member 151 is movably connected to the frame 110 between a first position and a second position vertically DH. The second cutting member 151 located in the first position is used to cut the (strip-shaped) sheet material 200, and the second cutting member 151 located in the second position is suspended above the sheet material 200. It should be noted that, because the second cutting member 151 is arranged along the first horizontal direction D1 and is relatively large, each second cutting member 151 is connected to at least two lifting members 152, and the at least two lifting members 152 are spaced apart along the first horizontal direction D1. For example Figure 1 In this process, there is one second cutting component 151, and each second cutting component 151 is connected to two lifting components 152.

[0075] Furthermore, to improve the smoothness of the movement of the second cutting member 151 relative to the frame 110 in the vertical direction DH, a guide structure 153 is also provided between the second cutting member 151 and the frame 110. Specifically, the guide structure 153 includes a guide groove 154 and a guide block 155 connected to each other. The guide groove 154 is provided in one of the frame 110 and the second cutting member 151, and the guide block 155 is provided in the other of the frame 110 and the second cutting member 151. For example... Figure 1 In the middle, the guide groove 154 is provided on the second cutting member 151, and the guide block 155 is provided on the frame 110.

[0076] Please continue reading. Figure 1 The sheet recycling system 100 also includes a hopper 161, which is connected to the frame 110. The hopper 161 is located downstream of the second cutting member 151 along the second horizontal direction D2. Figure 1 In the process, the hopper 161 has an upward opening, and the sheet material 200 processed by the first cutting member 131 and the second cutting member 151 is collected into the hopper 161.

[0077] Furthermore, the sheet recycling system 100 also includes a conveying device 162 and an extruder 163. The extruder 163 is located downstream of the hopper 161. The conveying device 162 is disposed between the hopper 161 and the extruder 163, and is connected to both the hopper 161 and the extruder 163. It is understood that the conveying device 162 is used to convey the sheet 200 located in the hopper 161 to the extruder 163. The conveying device 162 may be configured as, for example, a screw feeder, a vacuum pump material conveying pipe, etc. The sheet recycling system 100 also includes a first feeding device 164 and / or a second feeding device 165. Specifically, the first feeding device 164 is disposed in the extruder 163 and connected to the end of the conveying device 162 away from the hopper 161, and communicates the conveying device 162 and the extruder 163. The second feeding device 165 is disposed in the extruder 163, and communicates with the outside environment and the extruder 163. For example... Figure 1 The sheet material recycling system 100 includes a first feeding device 164 and a second feeding device 165, both of which are positioned above the extruder 163. The extruder 163 is, for example, a screw extruder, preferably a twin-screw extruder. Furthermore, the sheet material recycling system 100 also includes at least one metering device (not shown), which is positioned between the first feeding device 164 and / or the second feeding device 165. Preferably, there are two metering devices, respectively positioned in the first feeding device 164 and the second feeding device 165. Those skilled in the art will understand that the metering device is generally located at the inlet of the feeding device at the extruder 163. The metering device monitors the material flow rate / weight in real time using sensors (such as weighing sensors or speed encoders). The controller (such as a PLC) compares the set value with the actual value and adjusts the feeding speed of the feeding device based on algorithms such as PID, achieving high-precision and high-stability dynamic control of the material input, ensuring stable extrusion process and uniform product quality.

[0078] It is understood that the entire board recycling system 100 may also have a control device to coordinate the orderly operation of various components (first cutting component 131, second cutting component 151, transmission pressure roller 140, etc.) to finally complete the recycling of the board 200.

[0079] The following is a brief description of the entire process of board recycling.

[0080] First, select the number of first cutting components 131 according to the cutting requirements, and adjust the position of the first cutting components 131 relative to the first pivot axis 132. Start the entire system and place the sheet material 200 to be processed onto the placement platform 120. Along the traveling direction of the sheet material 200 (or the second horizontal direction D2), ... Figure 1The two drive rollers 140 are referred to as drive roller 140 No. 1 and drive roller 140 No. 2. The one located upstream is called drive roller 140 No. 1, and the one located downstream is called drive roller 140 No. 2. One end of the sheet 200 contacts drive roller 140 No. 1. Under the traction of drive roller 140 No. 1, the sheet 200 moves along the second horizontal direction D2 to the first cutting member 131 where it is cut into strips. Then, due to the rotation of drive roller 140 No. 1, the sheet 200 continues to move forward until it reaches drive roller 140 No. 2. At this point, both drive rollers 140 together drive the sheet 200 forward, thus moving it to the second cutting member 151. The second cutting member 151 cuts the strip of sheet 200, and the sheet 200 cut by the second cutting member 151 falls into the hopper 161. The conveying device 162 transports the sheet material 200 from the hopper 161 to the first feeding device 164. The first feeding device 164 is used for temporary storage and feeding of the sheet material 200, and the amount fed to the extruder 163 can be controlled by a metering device. The second feeding device 165 is used to add other required resins or additives, and the metering device at the second feeding device 165 can control the amount fed to the extruder 163. The extruder 163 can uniformly mix the materials from the first feeding device 164 and the second feeding device 165 and then extrude and granulate them.

[0081] In a specific implementation, for example, the speed of the transmission pressure roller 140 is set (adjustable from 0-1 m / min, for example, by setting specific parameters through a control device), and the cutting frequency of the second cutting component 151 is once every 6 seconds. The combination of these two parameters can control the fiber length of the cut sheet (3-30 mm). The sheet 200 cut by the first cutting component 131 becomes a strip with uniform width, and the sheet 200 cut by the second cutting component 151 becomes rectangular fragments with uniform length and width, which enter the hopper 161. Then, it is conveyed to the extruder 163 through the conveying device 162. If the fiber content in the recycled polypropylene composite sheet is 60%, polypropylene can be added to the second feeding device 165, and by adjusting the feeding ratio, granules with a fiber content of less than 60% can be obtained. Similarly, color masterbatch or other modified materials can be added to the second feeding device 165 to modify or change the color of the recycled granules.

[0082] According to the sheet recycling system of this utility model, the fiber size and fiber ratio of the recycled material can be effectively controlled during the recycling of sheets (e.g., continuous fiber reinforced thermoplastic resin sheets). The sheet recycling system effectively controls the fiber size during the recycling process of continuous fiber reinforced thermoplastic resin sheets through a simple and controllable cutting method, ensuring the uniformity of the recycled material particles' performance. Furthermore, through a designable regranulation process, the fiber content can be controlled or other functional improvements can be made.
