Description

Technical Field

[0001] This utility model relates to the technical field of material sorting and conveying devices, and in particular to a material sorting and conveying device with metal screening function. Background Technology

[0002] Currently, the continuous transportation of bulk materials in the industry mostly adopts various types of belt conveyors. Composite conveyor lines often require multiple transfers to distribute the materials.

[0003] In order to meet the processing requirements of plastic products, plastic needs to be crushed. Crushing lines generally crush first and then fine crush. During the conveying process, a small amount of metal is usually mixed in. When crushing, due to the high speed of the crusher rotor, when metal enters the crushing chamber, it will cause the rotor to collide violently with the metal, damaging the rotor and the internal structure of the housing. The maintenance cost is extremely high, the maintenance is difficult, and it also greatly affects the service life of the equipment.

[0004] In existing technologies, when a detector detects metal, the conveyor needs to be stopped, and the metal part will not continue to be conveyed forward. The metal is then manually picked out before the machine is restarted. This effectively solves the problem of metal not entering the crusher, but the overall work efficiency is low, which greatly affects the production capacity. At the same time, it requires manual supervision and selection, which is time-consuming and labor-intensive. Utility Model Content

[0005] In response to the shortcomings of the existing production technology, the applicant provides a material conveying device with metal screening function, which eliminates the need for machine downtime, has automatic material distribution function, eliminates the need for manual selection, increases production capacity, saves manpower, reduces costs, and improves work efficiency.

[0006] The technical solution adopted in this utility model is as follows:

[0007] A material distribution and conveying device with metal screening function includes a shredder connected to a conveyor. A metal detector is installed on the conveyor. A material distribution device is installed at the output end of the conveyor. The material distribution device is provided with a first output port and a second output port. The first output port is connected to a crusher, and the second output port is connected to a metal receiving hopper. A switchable blade is installed at the first output port.

[0008] Its further technical solution lies in:

[0009] The structure of the material distribution device is as follows: it includes a housing, one end of which is provided with an input port for connecting to a conveyor, the other end of which is provided with a first output port for connecting to a crusher, and the bottom of the housing is provided with a second output port for connecting to a metal receiving hopper; a fixed plate and rotatable blades are provided inside the housing, the blades are connected to the bottom of the housing via a rotating shaft, one end of which extends outside the housing, and a fixed frame is also provided fixed to the outer wall of the housing, on which a cylinder is fixed, the output end of which is fixed to the rotating shaft via a connecting plate, the extension and retraction of the cylinder causes the blades to rotate around the rotating shaft, thereby switching the blades between closing and opening the first output port.

[0010] The shell is a hollow thin-shell structure.

[0011] The top surface of the shell is provided with symmetrical lifting lugs.

[0012] The shell has symmetrical observation windows at both ends.

[0013] The input port, output port 1, and output port 2 are all square in shape.

[0014] The blade has a thin sheet structure, and a pressure plate is fixed to the outer side of the blade by fasteners.

[0015] The fixing plate has a bent structure and is integrated with the shell.

[0016] The conveyor is installed at an angle, and its bottom is supported by a support rod. An inclined brace is provided between the middle of the support rod and the bottom of the conveyor.

[0017] The angle between the conveyor and the horizontal plane is 30°.

[0018] The beneficial effects of this utility model are as follows:

[0019] This utility model features a compact and reasonable structure, and is easy to operate. By adding an automatic material distribution device to the existing metal detector, when the plastic products conveyed by the conveyor contain metal, the metal detector sends a signal to the pneumatic solenoid valve of the material distribution device. By activating the cylinder, the switching operation between output port 1 and output port 2 within the material distribution device is achieved. When the blade blocks output port 1, the part containing metal is allowed to exit through the designated channel, and the blade of the material distribution device is switched back. Plastic products without metal continue to enter the crusher for crushing. This method eliminates the need for machine shutdown and manual selection, thereby increasing production capacity, saving manpower and costs, and improving work efficiency.

[0020] This utility model also has the following advantages:

[0021] (1) The material distribution device described in this utility model has a simple structure, is easy to manufacture, and has a low cost.

[0022] (2) The material distribution device described in this utility model drives the rotation position of the blades through a cylinder, which is sensitive and reliable.

[0023] (3) The blade and the fixing plate described in this utility model work together to facilitate switching of the output port position.

[0024] (4) This utility model can be mainly used in the metal recycling industry. Attached Figure Description

[0034] The specific embodiments of this utility model are described below with reference to the accompanying drawings.

[0035] like Figures 1-7As shown, the material conveying device with metal screening function in this embodiment includes a shredder 1, which is connected to a conveyor 2. A metal detector 3 is installed on the conveyor 2. A material distribution device 6 is installed at the output end of the conveyor 2. The material distribution device 6 is provided with a first output port 605 and a second output port 609. The first output port 605 is connected to a crusher 7, and the second output port 609 is connected to a metal receiving hopper 8. An openable blade 606 is installed at the first output port 605.

[0036] The material distribution device 6 has the following structure: it includes a housing 601, one end of which is provided with an input port 603 that connects to the conveyor 2, and the other end of which is provided with a first output port 605 that connects to the crusher 7. The bottom of the housing 601 is provided with a second output port 609 that connects to the metal receiving hopper 8. Inside the housing 601, there is a fixed plate 613 and a rotatable blade 606. The blade 606 is connected to the bottom of the housing 601 through a rotating shaft 608. One end of the rotating shaft 608 extends out of the housing 601. It also includes a fixed frame 610 fixed to the outer wall of the housing 601. A cylinder 611 is fixed on the fixed frame 610. The output end of the cylinder 611 is fixed to the rotating shaft 608 through a connecting plate 612. The extension and retraction of the cylinder 611 causes the blade 606 to rotate around the rotating shaft 608, thereby switching the blade 606 between closing the first output port 605 and opening the first output port 605.

[0037] The shell 601 is a hollow thin-shell structure, which is easy to manufacture and has low cost.

[0038] The top surface of the housing 601 is provided with symmetrical lifting lugs 602 for easy installation and disassembly.

[0039] Symmetrical observation windows 604 are provided at both ends of the housing 601 for easy observation during use.

[0040] The inlet 603, the first outlet 605, and the second outlet 609 are all square in shape with large openings, resulting in high material conveying efficiency.

[0041] The blade 606 has a thin sheet structure, and a pressure plate 607 is fixed to the outer side of the blade 606 by fasteners.

[0042] The fixing plate 613 has a bent structure and is integrated with the housing 601, making the connection with the conveyor 2 smoother.

[0043] The conveyor 2 is installed at an angle, and the bottom of the conveyor 2 is supported by a support rod 5. An inclined brace 4 is provided between the middle of the support rod 5 and the bottom of the conveyor 2.

[0044] The angle between conveyor 2 and the horizontal plane is 30°.

[0045] This invention can install a start solenoid valve on the material distribution device 6. The metal detector 3 sends a signal to the pneumatic solenoid valve of the material distribution device 6 to control the action of the cylinder 611, which has a high degree of automation.

[0046] This utility model designs a material dispensing device 6 based on a metal detector 3. The specific structure, function and working method of the material dispensing device 6 are as follows:

[0047] It mainly includes key components such as housing 601, observation window 604, cylinder 611, connecting plate 612, blade 606, and fixing plate 613. During operation, if the material on conveyor 2 contains metal, when the metal material reaches the range of metal detector 3, metal detector 3 will send a signal to PLC program. After receiving the signal, PLC will delay and control the solenoid valve block in cylinder 611 of the material distribution device 6 to switch the position of piston of cylinder 611. Thus, through the linkage of connecting plate 612, when there is metal, blade 606 switches to the position of output port 605, and the material containing metal is discharged from the lower outlet (output port 609). After the metal material is separated, blade 606 switches back to the initial position, and the material will continue to smoothly enter crusher 7 for fine crushing.

[0048] This invention is easy to operate. By switching the working position of the blade 606, the working states of output port 605 and output port 609 can be easily switched. This effectively avoids the need to stop the machine to select metal in the prior art, which also requires special manpower to select the metal. This only solves the problem of metal not entering the crusher 7, resulting in low efficiency. However, this invention can control the switching of the material distribution device 6 through electrical signals, which solves the problem of separating metal materials without stopping the machine and without manual operation. At the same time, the structure is relatively simple, easy to manufacture and install, and low in cost. It not only ensures production capacity but also saves costs.
