Description

Technical Field

[0001] This utility model relates to the field of recycling, and more particularly to a recycling material anti-misuse system utilizing an RFID reader and RFID card. Background Technology

[0002] In the production of plastic products, molding processes such as injection molding, blow molding, and extrusion often generate scrap, sprues, or defective products. Since these scraps, sprues, or defective products are recyclable materials that can be reused, manufacturers usually add shredders to avoid waste. These shredders and scraps are crushed into fine particles for subsequent recycling or direct molding, thus achieving resource recycling.

[0003] In traditional recycled material processing, the transfer of recycled materials between the molding and crushing processes mainly relies on manual visual inspection or paper label verification. However, during continuous operation or batch switching, material mixing can easily occur due to operational negligence or label detachment. If different types of recycled materials are mixed, it will directly lead to fluctuations in the performance of the finished product or even scrapping. Utility Model Content

[0004] The purpose of this invention is to propose a recycling material anti-misoperation system using an RFID reader and RFID card to solve one or more technical problems existing in the background art.

[0005] To achieve this objective, the present invention adopts the following technical solution:

[0006] A recycling material error prevention system utilizing RFID readers and RFID cards includes a crushing controller, a molding controller, a first RFID reader / writer, a second RFID reader / writer, RFID tags, and a main controller. The main controller is electrically connected to the crushing controller, the molding controller, the first RFID reader / writer, and the second RFID reader / writer. The RFID tags carry model information corresponding to the recycled material. The first RFID reader / writer is located at the feed inlet of the crusher, and the second RFID reader / writer is located at the waste material recycling inlet of the molding machine. Both the first and second RFID readers / writers are used to read the model information of the recycled material carried by the RFID tags. The main controller is used to receive the recycled material model information read by the first and second RFID readers / writers and to feed back start / stop signals to the crushing controller or the molding controller based on the model information. The crushing controller is used to control the start and stop of the crusher, and the molding controller is used to control the start and stop of the molding machine.

[0007] Preferably, it also includes a recycled material recycling bin, the RFID tag is located on the front side of the recycled material recycling bin, and the bottom of the recycled material recycling bin is provided with rollers.

[0008] Preferably, the front side of the recycled material recycling bin is provided with a card slot, and the RFID tag is detachably installed in the card slot.

[0009] Preferably, it also includes a conveyor belt, the end of which is connected to the feed inlet of the crusher, and the control end of the conveyor belt is electrically connected to the main controller.

[0010] Preferably, it also includes a first touch screen and a second touch screen, both of which are electrically connected to the main controller.

[0012] Preferably, the device further includes a first position sensor and a second position sensor, which are respectively located at the feed inlet of the crusher and the waste material recycling inlet of the molding machine. The first position sensor and the second position sensor are electrically connected to the first RFID reader and the second RFID reader, respectively. When the first position sensor detects the presence of a recycled material recycling bin at the feed inlet of the crusher, the first RFID reader is switched from a closed state to an active state. When the second position sensor detects the presence of a recycled material recycling bin at the waste material recycling inlet of the molding machine, the second RFID reader is switched from a closed state to an active state.

[0013] The beneficial effects of this utility model are as follows: By setting a first RFID reader and a second RFID reader at the feeding port of the crusher and the recycling port of the molding machine respectively, the RFID tags bound with the model information of recycled materials are read to ensure that the recycled materials received from the recycling port of the molding machine are consistent with the recycled materials fed into the crusher. If the model read does not match the model information of the recycled materials being processed by the molding machine or the crusher, the operation of the equipment is interrupted by outputting a start / stop signal to the crushing controller or the molding controller. At the same time, the operator is reminded of the incorrect feeding or receiving of materials, which effectively prevents performance fluctuations or scrap caused by mixing materials. It does not require manual verification and solves the problems of misjudgment, omission or label detachment that are easily caused by manual visual inspection or paper labels, reducing downtime or rework caused by operational negligence.

[0019] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0020] This embodiment describes a recycled material misuse prevention system utilizing an RFID reader and RFID card, as shown in the attached document. Figure 1-3 The system includes a crushing controller 11, a molding controller 21, a first RFID reader 31, a second RFID reader 32, an RFID tag 4, and a main controller 5. The main controller 5 is electrically connected to the crushing controller 11, the molding controller 21, the first RFID reader 31, and the second RFID reader 32. The RFID tag 4 carries model information corresponding to the recycled material. The first RFID reader 31 is located at the feeding port of the crusher 1, and the second RFID reader 32 is located at the waste material recycling port of the molding machine 2. Both the first RFID reader 31 and the second RFID reader 32 are used to read the model information of the recycled material carried by the RFID tag 4. The main controller 5 is used to receive the model information of the recycled material read by the first RFID reader 31 and the second RFID reader, and to feed back start / stop signals to the crushing controller 11 or the molding controller 21 according to the model information. The crushing controller 11 is used to control the start and stop of the crusher 1, and the molding controller 21 is used to control the start and stop of the molding machine 2.

[0021] By setting a first RFID reader 31 and a second RFID reader 32 at the feeding port of crusher 1 and the recycling port of molding machine 2 respectively, the RFID tags 4 bound with recycled material model information are read to ensure that the recycled material received from the recycling port of molding machine 2 is consistent with the recycled material fed into crusher 1. If the model read does not match the recycled material model information being processed by molding machine 2 or crusher 1, the operation of crusher 1 or molding machine 2 is interrupted by outputting a start / stop signal to crusher controller 11 or molding controller 21. At the same time, the operator is reminded of the incorrect feeding or receiving of materials, which effectively prevents performance fluctuations or scrap caused by mixed materials. It does not require manual verification and solves the problems of misjudgment, omission or label detachment that are easily caused by manual visual inspection or paper labels, reducing downtime or rework caused by operational negligence.

[0022] Preferably, the system also includes a recycled material recycling bin 6, with an RFID tag 4 positioned on the front of the bin 6 and rollers 61 at the bottom. By providing the recycled material recycling bin 6 and the rollers 61 at its bottom, the system facilitates the transfer of recycled materials between the molding machine 2 and the crusher 1, reducing the time spent on manual handling. Fixing the RFID tag 4 to the front of the recycling bin ensures that the first RFID reader 31 and the second RFID reader 32 can stably read and write to it.

[0023] Preferably, the front side of the recycled material recycling bin 6 is provided with a card slot 62, and the RFID tag 4 is detachably installed in the card slot 62. Different types of recycled materials can use corresponding RFID tags 4. Operators only need to replace the tags in the card slot 62 to complete batch switching, without the need to relabel or configure electronic data, thus reducing downtime.

[0024] Preferably, the device also includes a conveyor belt 12, the end of which is connected to the feed inlet of the crusher 1, and the control end of the conveyor belt 12 is electrically connected to the main controller 5. By setting up the conveyor belt 12, it is convenient to transport the recycled material into the crusher 1, so that the recycled material enters the crusher 1 evenly for crushing and avoids feeding congestion.

[0025] Preferably, the system also includes a first touchscreen 71 and a second touchscreen 72, both of which are electrically connected to the main controller 5. The first touchscreen 71 and the second touchscreen 72 are respectively located at the feeding port of the crusher 1 and the waste material recycling port of the molding machine 2. By displaying information such as the current equipment status, the type of material being processed, and historical mixing warning records on the first touchscreen 71 and the second touchscreen 72, operators can easily obtain information about the equipment status.

[0026] Preferably, a buzzer is also included, which is electrically connected to the main controller 5 and is located at the waste material recycling port of the molding machine 2. The buzzer is provided so that when the second RFID reader 32 detects that the type of recycled waste does not match the current recycling material requirements, it triggers the buzzer to remind the operator to perform the correct operation, thus avoiding impact on subsequent production processes.

[0027] Preferably, the device further includes a first position sensor and a second position sensor, which are respectively located at the feeding port of the crusher 1 and the waste material recycling port of the molding machine 2. The first position sensor and the second position sensor are electrically connected to the first RFID reader 31 and the second RFID reader 32, respectively. When the first position sensor detects the presence of the recycled material recycling box 6 at the feeding port of the crusher 1, the first RFID reader 31 is switched from a closed state to an active state. When the second position sensor detects the presence of the recycled material recycling box 6 at the waste material recycling port of the molding machine 2, the second RFID reader 32 is switched from a closed state to an active state.

[0028] By setting a first position sensor and a second position sensor, it is possible to detect whether there is a recycled material recycling box 6 at the feeding port of the crusher 1 and the waste recycling port of the molding machine 2. If there is, the corresponding first RFID reader 31 or second RFID reader 32 will be activated to reduce the standby power consumption of the reader.
