Description

Technical Field

[0001] The utility model relates to the technical field of waste rubber recycling equipment, in particular to a waste rubber crushing and screening integrated machine. Background Art

[0002] With the rapid development of industrial production, waste rubber, as a common by-product in the production process, is increasing in quantity. In order to achieve the recycling of resources, the recycling and reuse of waste rubber have become an important topic. In the process of waste rubber treatment, crushing and screening are two key steps. Traditional waste rubber treatment equipment usually separates crushing and screening, which not only complicates the production process but also increases the floor area and energy consumption of the equipment. In addition, traditional equipment often has problems such as uneven crushing and low precision during the crushing process, and it is also difficult to effectively separate materials of different sizes during the screening process, resulting in uneven quality of the finished products.

[0003] Although there are various types of waste rubber crushing and screening equipment on the current market, most still adopt a single-function design and are difficult to meet the requirements of modern industry for efficient and precise processing. Especially when dealing with high-hardness or large-size waste rubber, the stability and durability of the equipment become key factors affecting production efficiency. At the same time, problems such as complex operation, difficult maintenance, and insufficient screening precision also limit the wide application of these equipment to a certain extent.

[0004] Therefore, there is an urgent need for a waste rubber crushing and screening equipment that can integrate crushing and screening functions, has high-efficiency and precise processing capabilities, and is easy to operate and maintain, in order to meet the needs of modern industrial production, improve resource utilization rate, and reduce production costs. Summary of the Utility Model

A sieve plate mounting opening is arranged at the lower end of the funnel mounting opening, and a screw mounting opening is arranged at the lower end of the sieve plate mounting opening;

[0013] The sieve plate is fixedly connected to the funnel through the sieve plate mounting opening and is located on the lower side of the tool box;

[0014] The screw is fixedly connected to the funnel through the screw mounting opening and is located in the funnel. A servo motor connection port is arranged at the left end of the screw;

[0015] Preferably, support feet are arranged at the four corners under the frame, and a material collecting box is arranged on the lower layer of the frame.

[0016] Preferably, the material collecting box is provided with partitions for collecting materials of different sizes. Two rows of pipes are fixedly connected to the left end of the material collecting box, and the two rows of pipes are arranged diagonally. A filter screen is also fixedly connected to the lower row of pipes in the material collecting box.

[0017] Preferably, an open box cover is arranged at the top of the tool box, and partitions are arranged in the gaps between each tool disk inside the tool box, and the partitions are fixedly connected to the tool box.

[0018] Preferably, a gasket is arranged between the transmission device and the tool box to enhance the connection strength.

[0019] Preferably, a bearing seat is arranged at the connection between the screw and the funnel to increase the rotation accuracy.

[0020] Preferably, small leakage holes are arranged on the left side of the partition of the funnel in the material collecting box, and large leakage openings are arranged on the right side of the partition of the funnel in the material collecting box.

[0021] Preferably, a reducer is fixedly connected to the reducer mounting opening and is located on the upper layer of the frame.

This device can achieve continuous operation, shorten the production cycle, and is suitable for large-scale industrial applications.

[0025] 2. Multiple groups of cutter heads cross-distributed on the driving shaft and the driven shaft, combined with the screw design driven by a servo motor, enable the material to be evenly subjected to cutting force during the crushing process. At the same time, the precise screening mechanism ensures the size consistency of the finished product particles, further improving the quality and uniformity of the finished product.

[0026] 3. By setting gaskets between the transmission device and the cutter box, and bearing seats between the screw and the funnel, the device exhibits high structural strength and rotational accuracy during operation.

At the same time, the complexity of manual participation is reduced, improving the safety of the working environment and the operation efficiency.

[0028] 5. Through the design of different-sized leakage holes in the funnel, the device realizes the automatic sorting of materials of different sizes, has stronger adaptability, and can meet various production requirements. This makes the application range of the device wider in different industrial fields. BRIEF DESCRIPTION OF THE DRAWINGS
