Description

Technical Field

[0001] The embodiments disclosed herein relate to the technical field of rubber processing equipment, and more specifically, to a rubber cutting mechanism for a rubber mixing machine. Background Technology

[0002] In the rubber product manufacturing industry, rubber compounding is a key pre-processing step, and the efficiency and quality of its raw material pretreatment directly affect the performance and production efficiency of the subsequent compounded rubber. Currently, the traditional rubber raw material cutting process has significant shortcomings, which restricts the industry's cost reduction, efficiency improvement, and capacity expansion.

[0003] Existing rubber raw material cutting processes generally employ a step-by-step processing model. This involves first using a strip cutter to cut large pieces of rubber raw material into strips, and then transferring the strips to a crushing machine for secondary crushing. This processing method, relying on two independent machines, not only significantly increases the company's equipment procurement, installation, and maintenance costs, but also reduces workshop space utilization due to the large footprint of the equipment. Furthermore, the transfer of rubber strips between the two machines consumes substantial manpower and time costs, and is prone to raw material loss and contamination, reducing raw material utilization.

[0004] Furthermore, the step-by-step processing flow significantly extends the production cycle, making it difficult to match the capacity of various equipment and coordinate processes, easily leading to production bottlenecks and severely impacting overall production efficiency. Against the backdrop of increasingly fierce market competition and rising production costs, traditional rubber cutting processes can no longer meet the urgent needs of modern rubber product companies for efficient and low-cost production. Therefore, developing a rubber cutting mechanism for rubber mixing machines that integrates strip cutting and crushing functions to achieve one-stop, efficient processing of rubber raw materials is of great significance for improving the production efficiency of rubber products and reducing overall costs. Utility Model Content

[0005] To overcome the above-mentioned defects, the embodiments of this disclosure provide a rubber cutting mechanism for a rubber mixing machine, which solves the technical problem that the prior art uses a strip cutter to cut large pieces of rubber raw materials into strips, and then transfers the rubber strips to a crushing device for secondary crushing. This processing method, which relies on two independent devices, not only significantly increases the enterprise's equipment procurement, installation and maintenance costs.

[0006] According to one aspect, at least one embodiment of the present disclosure provides a rubber cutting mechanism for a rubber mixing mill, comprising:

[0007] A platform and a feeding housing, wherein the feeding housing is fixed on the platform;

[0008] A propulsion and disassembly assembly is disposed within the frame and the feed housing;

[0009] A rectangular opening and a crushing and discharging assembly, wherein the rectangular opening is formed on the surface of the frame and the crushing and discharging assembly is disposed in the rectangular opening;

[0010] The propulsion and decomposition assembly includes a connecting frame, which is connected to the platform via a linear drive. A sealing propulsion block is provided at one end of the connecting frame, and the sealing propulsion block is slidably fitted inside the feed housing. A crushing screen is provided at one end of the feed housing, and the crushing screen is fixedly connected to one end of the feed housing by bolts.

[0011] As a further technical solution, the top of the feeding shell is provided with a feeding port, and a top frame is connected to one side of the feeding shell via a vertical linear drive. A top cover is connected to the top frame, and the top cover is closed inside the feeding port.

[0012] As a further technical solution, the crushing and discharging assembly includes a protective shell, which is disposed inside the rectangular opening. The protective shell is linearly slidably connected to both sides inside the rectangular opening, and a rotating shaft is electrically driven to rotate inside the protective shell.

[0013] As a further technical solution, an outer ring frame is provided on the rotating shaft, and a number of crushing blades are arranged around the surface of the outer ring frame. A collection and discharge hood is provided at the bottom of the frame, and a discharge port is opened at the bottom of the protective shell, with the discharge port located directly above the collection and discharge hood.

[0014] As a further technical solution, both the crushing mesh cover and the side surface of the sealing propulsion block have an arc-shaped transition structure, and the arc of the crushing mesh cover matches the arc of the outer ring frame surface.

[0015] As a further technical solution, one side of the protective outer shell is movably fitted onto the outside of the shredder.

[0016] As a further technical solution, a pair of internally threaded blocks are provided on the surface of the stand, the internally threaded blocks are located on both sides of the rectangular opening, and both sides of the protective shell are fixedly connected to the internally threaded blocks by bolts.

[0017] As a further technical solution, the top opening structure of the collection and discharge hood is larger than the overall size of the protective shell, and the bottom of the collection and discharge hood has a tapered structure with an inclined transition.

[0018] The beneficial effects of the embodiments disclosed herein are as follows:

[0019] In this disclosure, the propulsion and decomposition assembly achieves efficient strip-shaped segmentation of rubber raw materials through the cooperation of linear drive and crushing screen. The linear drive device drives the connecting frame and sealing propulsion block to slide smoothly within the feeding shell, pushing the raw material towards the crushing screen with a constant thrust. When the raw material passes through the screen, it is segmented into strips of uniform thickness. The specifications of the rubber strips can be adjusted by changing the crushing screen with different mesh sizes. The design of the feed port and the openable top cover facilitates the feeding and sealing of raw materials. The vertical linear drive top frame on the side ensures that the top cover fits tightly. This assembly avoids the independent equipment setting of traditional strip cutting machines, reduces equipment procurement, installation and maintenance costs, saves workshop space, and avoids loss and pollution during the raw material transfer process.

[0026] The present disclosure will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present disclosure and are not intended to limit the scope of the disclosure.

[0032] like Figures 1-4 As shown, a rubber cutting mechanism for a rubber mixing mill according to an embodiment of the present disclosure includes:

[0033] The platform 1 and the feeding housing 2 are fixed on the platform 1;

[0034] The propulsion and disassembly assembly 4 is disposed in the frame 1 and the feed housing 2;

[0035] A rectangular opening 3 and a crushing and discharging component 5 are provided. The rectangular opening 3 is opened on the surface of the frame 1, and the crushing and discharging component 5 is disposed in the rectangular opening 3.

[0036] The propulsion and decomposition assembly 4 includes a connecting frame 4-1, which is connected to the platform 1 via a linear drive. A sealing propulsion block 4-2 is provided at one end of the connecting frame 4-1. The sealing propulsion block 4-2 is slidably fitted inside the feed housing 2. A crushing screen 4-3 is provided at one end of the feed housing 2. The crushing screen 4-3 is fixedly connected to one end of the feed housing 2 by bolts. A feed inlet 4-4 is provided at the top of the feed housing 2. A top frame 4-5 is connected to one side of the feed housing 2 via a vertical linear drive. A top cover 4-6 is connected to the top frame 4-5 and the top cover 4-6 is closed inside the feed inlet 4-4.

[0037] In some examples, a propulsion and decomposition component 4 is designed to achieve efficient strip segmentation of rubber raw materials. A linear drive device composed of lead screws drives the connecting frame 4-1 and the sealing propulsion block 4-2 to slide smoothly within the feeding housing 2, propelling the rubber raw material towards the crushing screen 4-3 with a constant thrust. The crushing screen 4-3 is made of high-strength metal, and its mesh structure acts like a precision cutting mold. When the rubber raw material is squeezed through the screen by the sealing propulsion block 4-2, it is segmented into strips of uniform thickness. By replacing the crushing screen 4-3 with different mesh sizes and densities, the thickness of the segmented rubber strips can be flexibly adjusted to meet diverse production needs. The feed inlet 4-4 at the top of the feeding housing 2 and the openable top cover 4-6 facilitate rapid material feeding and sealing, preventing material from being squeezed out during processing. The vertical linear drive top frame 4-5 on the side, composed of cylinders, ensures a tight fit of the top cover 4-6, further enhancing the safety and stability of the feeding process and providing a high-quality strip-shaped raw material base for subsequent crushing processes.

[0038] like Figures 1-4 As shown in the figure, the crushing and discharging assembly 5 in this embodiment includes a protective shell 5-1, which is disposed inside the rectangular opening 3. The protective shell 5-1 is linearly slidably connected to both sides inside the rectangular opening 3. A rotating shaft 5-2 is electrically driven to rotate inside the protective shell 5-1. An outer ring frame 5-3 is provided on the rotating shaft 5-2. Several crushing blade holders 5-4 are arranged around the surface of the outer ring frame 5-3. A collection and discharge cover 5-5 is provided at the bottom of the frame 1. A discharge port 5-6 is opened at the bottom of the protective shell 5-1, and the discharge port 5-6 is located directly above the collection and discharge cover 5-5.

[0039] In some examples, a crushing and discharging assembly 5 is designed to achieve deep crushing and efficient discharge of rubber raw materials. The linear sliding design of the protective shell 5-1 within the rectangular opening 3 facilitates docking and separation with the crushing mesh 4-3, allowing for the replacement of crushing mesh 4-3 of different specifications. A power-driven rotating shaft 5-2, powered by a high-speed motor, drives the outer ring frame 5-3 to rotate at high speed. The evenly distributed crushing blades 5-4 on the outer ring frame act like a high-speed cutting array, further crushing the rubber strips extruded through the crushing mesh 4-3. The sharp blades and the powerful shearing force generated by the high-speed rotation rapidly crush the rubber strips into fine particles. The crushed rubber particles fall precisely into the collection and discharge hood 5-5 below through the discharge port 5-6 at the bottom of the protective shell 5-1, completing the discharge process.

[0040] This component, through its integrated design of high-speed rotary crushing and precise discharge, significantly improves the crushing efficiency and quality of rubber raw materials compared to the traditional step-by-step processing mode. At the same time, it avoids losses in the intermediate transfer process, realizing one-stop efficient processing of rubber raw materials from strip cutting to fine crushing.

[0041] For example, such as Figure 3 As shown, the side surfaces of the crushing mesh cover 4-3 and the sealing push block 4-2 are both arc-shaped transition structures, and the arc of the crushing mesh cover 4-3 matches the arc of the outer ring frame 5-3.

[0042] In some examples, the curved transition structure can better match the rotational curvature of the shredder holder 5-4, resulting in more uniform shredding of the extruded rubber.

[0043] For example, such as Figure 4 As shown, one side of the protective outer shell 5-1 is movably fitted onto the outside of the crushing mesh cover 4-3.

[0044] In some examples, the shredder 4-3 can be enclosed inside the active kit, preventing rubber from splattering out during the shredding process.

[0045] For example, such as Figure 1 As shown, a pair of internally threaded blocks 6 are provided on the surface of the frame 1. The internally threaded blocks 6 are located on both sides of the rectangular opening 3. Both sides of the protective shell 5-1 are fixedly connected to the internally threaded blocks 6 by bolts.

[0046] In some examples, the protective housing 5-1 is fixed in one position by means of an internally threaded block 6 and a bolt. The protective housing 5-1 does not need to be moved frequently; it can be fixed and locked by a simple sliding engagement.

[0047] For example, such as Figure 3As shown, the top opening structure of the collection and discharge hood 5-5 is larger than the overall size of the protective shell, and the bottom of the collection and discharge hood 5-5 has a tapered structure with an inclined transition.

[0048] In some examples, the larger opening structure of the discharge hood 5-5 allows all the falling rubber to be collected, and the converging structure makes the discharge more concentrated and easier to collect.

[0049] In actual use: After fixing the platform 1, fix the feed housing 2 on the platform 1. Install the propulsion and decomposition component 4 in the platform 1 and the feed housing 2. A rectangular opening 3 is opened on the surface of the platform 1 and a crushing and discharging component 5 is installed in it. The connecting frame 4-1 is connected to the platform 1 by a linear drive. A sealing propulsion block 4-2 is set at one end of the connecting frame 4-1 and slides inside the feed housing 2. A crushing screen 4-3 is fixed to one end of the feed housing 2 by bolts. A feed inlet 4-4 is opened at the top of the feed housing 2. A top frame 4-5 is connected to one side of the feed housing 2 by a vertical linear drive. A top cover 4-6 is connected to the top frame 4-5 to seal it inside the feed inlet 4-4. A protective housing 5-1 is set inside the rectangular opening 3 and slides linearly on both sides inside the rectangular opening 3. A rotating shaft 5-2 is connected inside the protective housing 5-1 by an electric drive. A device is installed on the rotating shaft 5-2. An outer ring frame 5-3 is placed, with several crushing blade holders 5-4 arranged around its surface. A collection and discharge hood 5-5 is installed at the bottom of the frame 1. A discharge port 5-6 is opened at the bottom of the protective shell 5-1 and is positioned directly above the collection and discharge hood 5-5. In use, rubber raw materials are put in through the inlet 4-4. The vertical linear drive drives the top frame 4-5 to close the inlet 4-4 with the top cover 4-6. The linear drive drives the connecting frame 4-1 to slide the sealing push block 4-2 inside the inlet shell 2, pushing the raw materials toward the crushing screen 4-3. The raw materials are cut into strips by the crushing screen 4-3. The protective shell 5-1 slides in the rectangular opening 3 and docks with the crushing screen 4-3. The electric drive rotating shaft 5-2 drives the outer ring frame 5-3 and the crushing blade holders 5-4 to rotate at high speed, crushing the strip-shaped raw materials. The crushed particles fall into the collection and discharge hood 5-5 through the discharge port 5-6.
