Description

Technical Field

[0001] This utility model relates to the field of tire manufacturing technology, specifically to a rubber material conveying anti-squeezing device. Background Technology

[0002] In tire manufacturing, tire carcass forming is a crucial step, as its winding precision, efficiency, and quality directly impact the tire's final performance and production efficiency. During the forming machine's operation, the carcass feeder conveys the carcass material to the folding drum via a conveyor belt for winding and forming.

[0003] However, during the feeding process, tire material occasionally adheres to the conveyor belt surface, causing the rubber compound to accumulate and be squeezed along the conveying path. This squeezing not only causes unplanned equipment downtime but also requires manual intervention to remove the accumulated rubber, negatively impacting production efficiency and the stability of continuous equipment operation. Therefore, the existing technology urgently needs further improvement. Utility Model Content

[0004] To address the shortcomings of existing technologies, a rubber material conveying anti-squeezing device is proposed, which solves the problem of the negative impact of material squeezing on production efficiency and the stability of continuous equipment operation in the aforementioned background technologies.

[0005] To achieve the above objectives, the present invention proposes the following technologies: A rubber material conveying anti-squeezing device includes a peeling plate, which is fixed on a support frame below the conveyor belt to peel off the rubber material adhering to the conveyor belt and prevent the rubber material from moving with the conveyor belt into the gap between the support frame and the conveyor belt, causing squeezing.

[0006] Furthermore, the top of the peeling plate is provided with a peeling blade, and the longitudinal section of the peeling blade has an acute angle, which is tangent to the inner surface of the end of the conveyor belt to achieve the peeling of the rubber material.

[0007] Furthermore, the end of the peeling plate is machined with a bevel to form the peeling edge, the bevel being located on the side of the peeling plate away from the conveyor belt.

[0008] Furthermore, the peeling plate is inclined and located inside the rubber material feeding path, and the shape of the peeling blade matches the surface shape of the conveyor belt.

[0009] Furthermore, it also includes a fixing plate, which is located below the peeling plate and is fixedly connected to the support frame, thereby providing support for the peeling plate and positioning it.

[0010] Furthermore, the stripping plate and the fixing plate are connected by a positioning hinge to facilitate adjusting the angle of the stripping plate so that it is close to the surface of the conveyor belt.

[0011] Furthermore, the peeling edge is a continuous smooth edge that matches the shape of the inner surface of the conveyor belt, and its cross-section has an acute angle of 30° to 45°.

[0012] Furthermore, the lengths of both the stripping plate and the fixing plate are less than the width of the conveyor belt to prevent interference with the sides of the support frame.

[0013] Compared with the prior art, the comprehensive effects brought about by this utility model include: By incorporating a stripping plate positioned below the conveyor belt and maintaining a suitable gap with the belt's underside, the edge of the stripping plate scrapes or peels away any adhering adhesive material as it passes, allowing it to continue its conveying path and preventing material extrusion. This simple and reliable stripping plate design achieves active stripping of adhering adhesive material, effectively preventing equipment malfunctions caused by material squeezing into gaps. This not only reduces maintenance frequency and downtime but also improves the continuity and safety of the conveying system. Attached Figure Description

[0016] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0017] In this document, terms such as “up,” “down,” “left,” “right,” and “top” indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0018] like Figures 1 to 3As shown, a rubber material conveying anti-squeezing device includes a peeling plate 1, which is fixed on a support frame 3 below the conveyor belt 2 to peel off the rubber material 4 adhering to the conveyor belt 2, thereby preventing the rubber material 4 from moving with the conveyor belt 2 into the gap between the support frame 3 and the conveyor belt 2 and causing squeezing.

[0019] During the process of the tire material being transported to the folding drum for winding and forming by the tire material feeding frame via the conveyor belt 2, the rubber material 4 falls onto the surface of the conveyor belt 2 through the feeding device. However, due to the high viscosity of the rubber material 4, if the adhesive rubber material 4 is not removed in time when the conveyor belt 2 is running, it will move with the conveyor belt 2 into the narrow gap between the support frame 3 and the conveyor belt 2, resulting in material extrusion, accumulation of rubber material 4, or even equipment shutdown.

[0020] By installing a stripping plate 1, positioned below the conveyor belt 2 and maintaining an appropriate gap with its lower surface, the edge of the stripping plate 1 scrapes or peels the adhesive material 4 from the conveyor belt 2 as it passes, allowing it to continue its conveying path and thus avoiding material squeezing. This simple and reliable stripping plate 1 design achieves active stripping of the adhesive material 4, effectively preventing equipment malfunctions caused by the material 4 squeezing into gaps. This not only reduces maintenance frequency and downtime but also improves the continuity and safety of the conveying system.

[0021] In practical applications, the stripper plate 1 is typically made of wear-resistant metal (such as stainless steel) and is fixed to the support frame 3 at an appropriate position by bolts or welding. The support frame 3 itself is a component of the conveyor belt system, used to support the conveyor belt 2 and maintain its tension.

[0022] In the rubber material conveying anti-squeezing device of this embodiment, the top of the peeling plate 1 is provided with a peeling blade 5. The longitudinal section of the peeling blade 5 has an acute angle, which is tangent to the inner surface of the end of the conveyor belt 2 to achieve peeling of the rubber material 4.

[0023] The peeling blade 5 is arranged tangentially or nearly tangentially to the inner surface of the conveyor belt 2, ensuring linear contact rather than surface contact between the blade and the conveyor belt 2 during peeling. This design minimizes the contact area, reduces frictional resistance, and makes the peeling action smoother.

[0024] The acute-angled peeling blade 5 enables efficient peeling with lower force, reducing the risk of scratching the conveyor belt 2 and extending its lifespan. Simultaneously, the tangential design ensures a smooth peeling process, preventing the rubber material 4 from splashing due to sudden peeling and improving operational safety.

[0025] Specifically, the end of the peeling plate 1 is machined with a bevel 6 to form the peeling edge 5, and the bevel 6 is located on the side of the peeling plate 1 away from the conveyor belt 2.

[0026] By processing the end bevel 6, the bevel structure allows the adhesive material 4 to be naturally guided and detached when it comes into contact with the cutting edge, reducing the adhesion and accumulation of the adhesive material 4 at the cutting edge and further improving the peeling reliability.

[0027] Specifically, the peeling edge 5 is a continuous smooth edge that matches the shape of the inner surface of the conveyor belt 2, and its cross-section has an acute angle of 30° to 45°.

[0028] In practice, the bevel 6 can be machined through a single milling or wire cutting. The angle of the bevel 6 is consistent with the acute angle of the peeling cutting edge, ensuring sufficient sharpness. The surface of the cutting edge is polished to ensure no breaks or protrusions, thus forming a uniform peeling line. The bevel 6 must be smooth and continuous, without burrs, to avoid excessive wear on the conveyor belt. For example, a 40° bevel can be machined to create a consistent cutting edge profile.

[0029] The continuous smooth cutting edge avoids localized stress concentration, reduces resistance fluctuations during the peeling of the rubber compound 4, and makes the conveyor belt 2 run more smoothly. The acute angle range of 30° to 45° strikes a balance between sharpness and durability.

[0030] Preferably, the fixing plate 7 is made of 304 or 316 stainless steel plate with a thickness of 3mm-5mm. If stainless steel is used, the cutting edge that contacts the conveyor belt 2 must be polished to a surface roughness Ra≤0.8μm to reduce frictional resistance.

[0031] In the rubber material conveying anti-squeezing device of this embodiment, the peeling plate 1 is inclined and located inside the rubber material 4 feeding path, and the shape of the peeling blade 5 matches the surface shape of the conveyor belt 2.

[0032] The tilted setting allows the peeling plate 1 to be more accurately aligned with the area where the rubber material 4 and the conveyor belt 2 are prone to sticking, improving the peeling targeting; while the shape matching design ensures uniform contact between the blade edge and the surface of the conveyor belt 2, avoiding local stress concentration, thereby reducing wear and noise.

[0033] In actual installation, the peeling plate 1 can be tilted at an angle as needed to make it closer to the discharge trajectory of the rubber material 4 when it separates from the conveyor belt 2. At the same time, the shape of the peeling blade 5 is adapted to the type of conveyor belt 2 (such as a flat belt or a trough belt). For example, for an arc-shaped conveyor belt 2, the peeling blade 5 is processed into a corresponding curvature.

[0034] The adhesive conveying anti-squeezing device in this embodiment also includes a fixing plate 7, which is located below the peeling plate 1 and is fixedly connected to the support frame 3, thereby providing support for the peeling plate 1 and realizing the positioning of the peeling plate 1.

[0035] The introduction of the fixing plate 7 enhances the overall structural rigidity, preventing the peeling plate 1 from shifting or deforming due to the impact of the adhesive 4 during long-term use. This modular design facilitates disassembly and maintenance, while also distributing the load during the peeling process and improving the durability of the device.

[0036] The fixing plate 7 is usually a plate-shaped structure and is connected to the support frame 3 by welding or bolts. The peeling plate 1 is installed on top of the fixing plate 7 by fasteners.

[0037] Preferably, in order to facilitate the disassembly of the fixing plate 7 and the anti-squeezing device, bolts are used to connect the fixing plate 7 and the support frame 3.

[0038] In the rubber material conveying anti-squeezing device of this embodiment, the peeling plate 1 and the fixing plate 7 are connected by a positioning hinge 8 so as to adjust the angle of the peeling plate 1 so that it is close to the surface of the conveyor belt 2.

[0039] The adjustable angle design allows the device to flexibly adapt to different specifications of conveyor belt 2 or rubber material 4 (such as changes in the height of conveyor belt 2), improving its versatility. The adjustment process is simple and quick, optimizing the peeling effect without replacing parts, thus reducing operating costs.

[0040] Specifically, the positioning hinge 8 can be a hinge structure with locking bolts, allowing the operator to loosen the bolts and manually adjust the angle of the peeling plate 1 before locking it in place; or a heavy-duty flat (hinged) hinge can be used, whose robust structure can withstand continuous mechanical vibration.

[0041] In the rubber material conveying anti-squeezing device of this embodiment, the lengths of the peeling plate 1 and the fixing plate 7 are both less than the width of the conveyor belt 2, so as to prevent interference with both sides of the support frame 3.

[0042] The above-mentioned size design avoids the risk of collision with the support frame 3 during installation or operation, and ensures the compatibility of the device in narrow spaces.

[0043] Specifically, the length of the fixing plate 7 should be slightly shorter than the effective width of the conveyor belt 2 (for example, if the conveyor belt width is 1000mm, the length of the fixing plate 7 can be 980mm) to prevent interference with the sides of the frame. The width (height) is determined according to the installation space, and is usually 80mm-150mm.

[0044] According to a preferred embodiment of this application, the rubber material conveying anti-squeezing device includes core components such as a peeling plate 1 and a fixing plate 7. The peeling plate 1 is fixed on a support frame 3 below the conveyor belt 2, and its position and angle are optimized to adapt to different conveying conditions.

[0045] In practical use, the device is first installed on the support frame 3 of the conveyor belt system, and the angle of the peeling plate 1 is adjusted so that its cutting edge is tangent to the inner surface of the conveyor belt 2. After the conveyor belt 2 is started, the rubber material 4 falls, and the adhered parts are automatically peeled off by the peeling plate 1. Throughout the process, the device has a simple structure and reliable operation.

[0046] Specifically, when installing the anti-squeezing device onto the support frame 3: First, determine the installation location: the device should be installed near the area where the rubber material 4 naturally detaches from the conveyor belt 2 or is prone to adhesion; the specific location should be below the conveyor belt 2, where the separation process of the rubber material 4 from the belt surface can be clearly observed.

[0047] Then proceed with the installation: Step 1: Shut down and disconnect power. Ensure the molding machine has completely stopped running, disconnect the power source, and lock and tag it.

[0048] Step 2, Positioning Marking. Place the fixing plate 7 (not installed yet) in the predetermined position, manually rotate the conveyor belt 2, and observe the relative relationship between the peeling plate 1 and the belt surface. Mark the approximate mounting hole positions of the fixing plate 7 on the equipment support frame 3 using a marker.

[0049] Step 3, install the fixing plate 7. Attach the main body of the fixing plate 7 to one side of the support frame below the conveyor belt 2. Use an M8 x 25mm bolt to pass through the elongated hole from the other side of the support and screw it into the threaded hole on the fixing plate 7. Do not tighten all bolts at this time.

[0050] Step 4, Adjustment and Positioning (Key Step). Manually rotate the conveyor belt 2 to make it run slowly; finely adjust the position of each support so that the peeling blade 5 of the peeling plate 1 forms tangential contact with the inner surface of the conveyor belt 2.

[0051] Clearance / Pressure Parameters: Ideally, the cutting edge should make slight contact with the conveyor belt 2 without generating significant resistance. This can be checked using a feeler gauge on an A4 sheet of paper: the paper should be able to be pulled out between the cutting edge and the belt surface, and a slight friction should be felt. It is strictly forbidden to press the peeling plate 1 too tightly, as this will increase the running resistance of the conveyor belt 2 or accelerate wear.

[0052] Step 5, final tightening. After the position adjustment is complete, tighten the bolts connecting the fixing plate 7 to the support frame 3 below the conveyor belt 2 in sequence. Check again by rotating the machine to confirm that there is no interference.

[0053] The modular design achieves efficient anti-extrusion material control, significantly reducing equipment failure rate; adjustable angles and standardized components improve adaptability and economy; at the same time, the optimization of the peeling edge 5 reduces energy consumption and maintenance requirements.
