[0003] Waste rubber recycling is an important area of ​​resource recycling and environmental protection. Existing technologies, such as ordinary crushers, mainly process waste rubber by cutting and crushing, but they cannot effectively separate the metal fibers and other impurities mixed in the rubber, and cannot meet higher processing requirements. Therefore, there is a need for improvement. Utility Model Content

[0004] This utility model provides a waste rubber recycling device that can effectively improve the recycling efficiency and quality of waste rubber, and has a wide range of applications. It can be applied to various types of rubber waste and can meet higher processing requirements. It solves the technical problems in the existing technology where the current waste rubber recycling methods are relatively simple, cannot effectively separate metal fibers and other impurities mixed in the rubber, and cannot meet higher processing requirements.

[0005] The above-mentioned technical problem of this utility model is solved by the following technical solution: a waste rubber recycling device includes a support frame, on which a recycling device is mounted. The recycling device consists of a pre-treatment crushing module, a secondary crushing module, a magnetic screening module, and a hot-melt module, arranged from top to bottom. The pre-treatment crushing module at the top has a feed inlet, and the hot-melt module at the bottom has a discharge outlet. During processing, waste material is poured in through the feed inlet at the top. The waste material passes through the pre-treatment crushing module for initial crushing, the secondary crushing module for fine crushing, the magnetic screening module for separating metal fragments, and the hot-melt module for hot-melting and shaping. Finally, it is discharged from the discharge outlet for recycling. The recycling device of this utility model can ensure thorough crushing, high crushing efficiency, and improve the separation efficiency of metal impurities, thus meeting the higher processing requirements in actual production.

[0006] Preferably, material conveying pipes are provided between the pretreatment crushing module and the secondary crushing module, and between the secondary crushing module and the hot-melting module. The material conveying pipe between the pretreatment crushing module and the secondary crushing module has a downward-convex conical structure to ensure accurate material discharge, while the material conveying pipe between the secondary crushing module and the hot-melting module has a straight cylindrical structure.

[0007] Preferably, the pretreatment crushing module includes a pretreatment chamber, inside which are several relatively rotating pre-crushing gears. The function of the pretreatment chamber is to initially divide large pieces of rubber waste into smaller pieces for further fine crushing.

[0008] Preferably, the surface of the pre-crushing gear is provided with several spiral pre-crushing blades. After being squeezed by the pre-crushing blades, large pieces of rubber waste will be divided into several smaller pieces, which facilitates further fine crushing and can also improve crushing efficiency.

[0009] Preferably, the secondary crushing module includes a secondary processing chamber connected to the preprocessing chamber, and the secondary processing chamber is equipped with several relatively rotating crushing gears. The function of the crushing gears is to crush small pieces of rubber waste, facilitating subsequent hot melt molding.

In this invention, one of the crushing gears can be moved as a whole by a hydraulic push rod, and its movement distance can be controlled by the system to be between 1-10mm.

[0011] Preferably, both the crushing gear and the pre-crushing gear are driven by a motor or a pulley structure. The crushing gear in this invention will be described using a motor-driven example.

[0012] Preferably, the magnetic screening module includes a conveyor belt spaced apart within a conveying pipe between the secondary crushing module and the hot-melting module. The conveyor belt is driven by a motor, and its surface is embedded with several electromagnetic plates that are sequentially connected at their ends. The conveyor belt is arranged diagonally on the left and right sides, with the left and right sides rotating clockwise and counterclockwise, respectively. Several rectangular electromagnetic plate modules are embedded in the surface of the conveyor belt, each containing a built-in electromagnetic module and requiring no external power supply. Rubber fragments fall sequentially onto the conveyor belt, while metal fragments are attracted to the surface of the electromagnetic plates and moved to the outside with the conveyor belt.

[0013] Preferably, the magnetic screening module also includes a scraper plate mounted on the outside of the support and connected to the conveyor belt. The scraper plate is installed on the outer support and corresponds to the conveyor belt, which can scrape off and collect metal fragments from the surface of the electromagnetic plate, thereby ensuring that the conveyor belt can continuously transport materials.

[0014] Preferably, the hot-melt module includes a hot-melt box connected to the secondary crushing module. The inner wall of the hot-melt box is embedded with an electric heating layer, and the hot-melt box is equipped with stirring blades. The crushed rubber waste falls into the hot-melt box for hot-melt treatment, and the hot-melted rubber waste can be formed and discharged from the discharge port.

[0015] Therefore, the waste rubber recycling device of this utility model has the following advantages: it can effectively improve the recycling efficiency and quality of waste rubber, and has a wide range of applications, applicable to a variety of rubber wastes, and can meet higher processing requirements.
