Description

Technical Field

[0001] This invention relates to the field of tire processing technology, and more specifically, to a steel cord fabric extrusion, adhesive coating and cutting integrated machine and its production process. Background Technology

[0002] Small-angle belt ply, 90-degree carcass, and 0-degree belt ply are essential semi-finished products in tire production. Currently, the production of these three products typically utilizes four dedicated production lines: a steel wire calendering line, a small-angle steel cord fabric production line, a 90-degree steel cord fabric production line, and a 0-degree belt ply production line. The technical solution is as follows: First, a dedicated steel cord fabric calendering line calenders and coats the steel wires with adhesive to produce adhesive-coated steel cord fabric, which is then wound into large rolls for the cutting machine. Second, on a dedicated small-angle steel cord fabric cutting line, the calendered steel cord fabric is unrolled and cut according to different angle and width requirements, then spliced ​​and wound to complete the production of the small-angle steel wire belt ply. Finally, a dedicated 90-degree steel cord fabric cutting line unrolls the calendered steel cord fabric, cuts it according to different width requirements, then splices and wound to complete the production of the 90-degree steel cord carcass. Then, a dedicated 0-degree belt layer production line is used to apply adhesive to several steel wires through an extruder, cool them, and wind them up to complete the production of the 0-degree belt layer.

[0003] The advantages of the above production methods are high production efficiency and large capacity, while the disadvantages are high equipment costs and large floor space requirements. This means that the above methods are mainly suitable for the mass production of all-steel and semi-steel tires, with an annual output of one million to ten million sets. For engineering tires and agricultural tires, which are mostly produced in small batches of hundreds of thousands of sets per year, the methods suffer from problems such as excessively high costs and large floor space requirements.

[0016] Furthermore, the 0-degree belt layer winding device is located at a position where the reversing device has been rotated 90 degrees.

[0017] According to another aspect of the present invention, a production process method for a steel cord fabric extrusion, adhesive coating, and cutting integrated machine is provided, comprising: placing a steel wire spindle in an extrusion and adhesive coating device, the extrusion and adhesive coating device extrudes the steel wire and applies adhesive to form a steel cord fabric; a reversing device rotates to reverse the direction of the steel cord fabric processed by the extrusion and adhesive coating device; the steel cord fabric reversed by the reversing device enters a cutting device and is cut into a predetermined angle and width; the cut steel cord fabric is conveyed to a belt layer processing device or a tire carcass processing device for processing the belt layer or tire carcass fabric.

[0019] Furthermore, when the cut steel wire cord fabric is conveyed to the belt layer processing device for belt layer processing, the steel wire cord fabric, after being reversed by the reversing device, enters the centering conveyor device and is positioned and guided before being conveyed to the upper and lower cutting blade positions of the cutting host. The rotation angle of the centering conveyor device is 15°-70° to meet the cutting range of 15°-70° for small-angle belt layers. After cutting, the clamping and pulling device pulls the material according to the required angle and width of the belt layer. During pulling, the lifting bracket of the belt layer cutting conveyor belt is raised to support the material. During cutting, the lifting bracket... As the upper cutter descends, the cut belt layer is conveyed by the belt layer cutting conveyor belt to the belt layer splicing device. The belt layer splicing device connects the two belt layers. The continuous belt layer that has completed the splicing is conveyed out of the belt layer splicing device by the belt layer unloading conveyor belt. The belt layer balancing roller device converts the intermittent unloading process of the splice into a continuous running process and conveys it to the next station. The belt layer film application device performs the film application process. The belt layer with film applied is wound onto the I-beam or trolley by the conveyor belt layer winding device.

This allows for the simultaneous production of both the belt layer and the tire carcass, with a production capacity fully capable of meeting the small-batch production needs of engineering tires and agricultural tires. Simultaneously, it reduces the equipment footprint and lowers equipment investment costs. Specifically, the extrusion and adhesive application device guides and organizes the steel wires and applies adhesive to form steel cord fabric. The steel cord fabric continues to be conveyed, and during this process, a reversing device adjusts the conveying direction of the steel cord fabric to meet the processing requirements of the belt layer or tire carcass. After the reversing device, it enters the cutting device, where it is cut at the required angle and width to form the shape required for subsequent processing. After cutting, it is conveyed to the subsequent belt layer processing device or tire carcass processing device for further processing of the belt layer or tire carcass fabric, forming the belt layer or tire carcass fabric. In this embodiment, the production lines for steel cord extrusion, adhesive application, and cutting are arranged along the first direction, while the production lines for belt layer processing and tire carcass processing are arranged along the second direction. This creates a certain angle between the two lines, thus meeting the processing requirements of belt layers or tire carcass cords at different angles. This arrangement achieves integrated production of steel cord extrusion, adhesive application, cutting, and subsequent processing. The overall equipment has a small footprint and low cost, making it suitable for small-batch production of engineering tires and agricultural tires, reducing the footprint by 70% and saving 60% in costs.

[0033] To address the problem that existing tire production lines are not suitable for small-batch production, this invention provides an integrated machine for extruding, coating, and cutting steel cord fabric and its production process.

[0034] like Figures 1 to 4The machine shown is an integrated extrusion, adhesive application, and cutting machine for steel cord fabric. It includes an extrusion and adhesive application device for extruding and applying steel cord, a reversing device 7, a cutting device, a belt layer processing device, and a tire carcass processing device. The reversing device 7 is located at the rear end of the extrusion and adhesive application device and can adjust the conveying direction of the steel cord fabric. The cutting device is located at the rear end of the reversing device 7 and can cut the steel cord fabric according to the required angle and width of the belt layer or tire carcass fabric. The belt layer processing device is located at the rear end of the cutting device and processes the cut steel cord fabric into a belt layer. The tire carcass processing device is located at the rear end of the cutting device and processes the cut steel cord fabric into a tire carcass fabric. The extrusion and adhesive application device, the reversing device 7, and the cutting device are arranged sequentially along a first direction, while the belt layer processing device and the tire carcass processing device are arranged sequentially along a second direction, forming an angle between the first and second directions. The belt layer processing device and the tire carcass processing device are located on opposite sides of the cutting device along the second direction.

[0035] This embodiment achieves integrated extrusion, adhesive application, cutting, belt layer processing, and tire carcass processing of steel cord fabric through the synergistic interaction of the aforementioned components. It can simultaneously meet the production needs of both the belt layer and the tire carcass, with a production capacity fully capable of satisfying the small-batch production requirements of engineering tires and agricultural tires. Simultaneously, it reduces equipment footprint and lowers equipment investment costs. Specifically, the extrusion and adhesive application device guides and arranges the steel wires and applies adhesive to form steel cord fabric. The steel cord fabric continues to be conveyed, and during this process, the conveying direction is adjusted by the reversing device 7 to meet the processing requirements of the belt layer or tire carcass. After the reversing device 7, it enters the cutting device, where it is cut according to the required angle and width, shaping the steel cord fabric into the shape required for subsequent processing. After cutting, it is conveyed to the subsequent belt layer processing device or tire carcass processing device for further processing of the belt layer or tire carcass fabric, forming the belt layer or tire carcass fabric. In this embodiment, the production lines for steel cord extrusion, adhesive application, and cutting are arranged along the first direction, while the production lines for belt layer processing and tire carcass processing are arranged along the second direction. This creates a certain angle between the two lines, thus meeting the processing requirements of belt layers or tire carcass cords at different angles. This arrangement achieves integrated production of steel cord extrusion, adhesive application, cutting, and subsequent processing. The overall equipment has a small footprint and low cost, making it suitable for small-batch production of engineering tires and agricultural tires, reducing the footprint by 70% and saving 60% in costs.

[0059] For the extrusion coating process, the specific process of the extrusion coating device extrudes steel wire and coats it with adhesive to form steel wire cord is as follows: the steel wire spindle is placed in the spindle room guide device 1 and after being leveled and guided, it is inserted into the steel wire coating head 4.

[0060] The rubber feeding conveyor belt 2 feeds the rubber raw material into the extruder 3, thus feeding the rubber material into the extruder 3.

[0061] Extruder 3 plasticizes and extrudes the rubber material into the steel wire coating die head 4 for steel wire coating;

[0062] The steel wire passing through the steel wire gluing head 4 enters from the steel wire threading plate and then passes directly through the upper and lower flow channels for gluing. After the steel wire is glued in the head, it passes through the gluing orifice plate and is pulled out from the gluing orifice plate under the pressure of the head and the traction of the cooling drum device 5, thus completing the hot gluing of the steel wire and forming a steel wire curtain.

[0063] The steel wire cord is pulled out from the steel wire adhesive applicator head 4 to the cooling drum device 5, and is cooled by being wound around the multiple cooling drums of the cooling drum device 5;

[0064] After cooling, the steel cord fabric enters the storage device 6, where it is floated and stored by upper and lower floating rollers and then conveyed by the subsequent reversing device 7, so as to match the extrusion and adhesive application speed with the subsequent production speed.

[0065] The aforementioned front-end processes are the same when producing small-angle belt layers and 90-degree tire carcass cord fabrics. The difference between the two processes lies in the subsequent procedures.

[0066] The small-angle belt layer is processed using a belt layer processing device. Specifically, when processing the small-angle belt layer...

[0067] The steel wire cord fabric, after being redirected by the reversing device 7, enters the centering conveyor 8 and is then positioned and guided before being conveyed to the upper and lower cutting blade positions of the cutting host 9. The centering conveyor 8 rotates along the rotation center according to the cutting angle, with a rotation angle of 15°-70°, thereby satisfying the cutting range of 15°-70° for small-angle belt layers;

[0068] After cutting, the clamps of the clamping and pulling device 10 with pneumatic clamps are driven by XY dual-axis AC servo motors to pull and cut the belt layer fabric according to the required angle and width. During pulling, the lifting bracket of the belt layer cutting conveyor belt 11 is raised to support the material. During cutting, the lifting bracket falls together with the upper cutter. The cut belt layer is placed on the strip telescopic conveyor belt by the lifting bracket of the belt layer cutting conveyor belt 11 and transported to the joint position of the belt layer joint device 12.

[0069] At the joint position of the belt layer joint device 12, the front and rear belt layers are joined together;

[0070] The continuous belt layer that completes the docking joint via the belt layer joint device 12 is conveyed out of the joint position of the belt layer joint device 12 by the belt layer unloading conveyor belt 13.

[0071] The intermittent unloading process of the joint is converted into a continuous operation process by the belt layer balance roller device 14, and then conveyed to the next station.

[0072] The film wrapping process is carried out by the belt-layer film application device 15;

[0073] The belt layer with the film applied is finally wound onto the I-beam or trolley by the conveyor belt layer winding device 16.

[0074] The above completes the production of the small-angle belt layer.

[0075] The production and processing of 90-degree tire carcass cord fabric is carried out through a tire carcass processing device. Specifically, during the processing of 90-degree tire carcass cord fabric...

[0076] The steel cord fabric, after being redirected by the reversing device 7, enters the centering conveyor 8 and is then positioned and guided before being conveyed to the upper and lower cutting blade positions of the cutting host 9. The centering conveyor 8 rotates along the rotation center according to the cutting angle, with a rotation angle of 90 degrees, thereby satisfying the 90-degree cutting of the tire cord fabric.

[0077] After cutting, the clamps of the clamping and pulling device 10 with pneumatic clamps are driven by XY dual-axis AC servo motors, and the cutting host 9 cuts the 90-degree tire cord fabric according to the required angle and width. During the pulling process, the lifting brackets of the belt layer cutting conveyor belt 11 and the tire body cutting conveyor belt 17 are raised together to support the material. During cutting, the lifting bracket of the belt layer cutting conveyor belt 11 falls together with the upper cutter. The cut cord fabric is pulled a second time by the clamps, pulling the tire body cord fabric from the cutter position to the position of the tire body cutting conveyor belt 17. Then the lifting bracket of the tire body cutting conveyor belt 17 falls, placing the cut cord fabric on the strip telescopic belt of the tire body cutting conveyor belt 17.

[0078] The cut 90-degree tire carcass cord is conveyed by the strip telescopic belt of the tire carcass cutting conveyor belt 17 to the joint position of the tire carcass joint device 18.

[0079] The carcass joint device 18 connects two carcass ply fabrics together. After unloading, the joint baffle is raised, and the carcass ply fabric is sent to the carcass joint device 18 by the carcass cutting conveyor belt 17. The pressing device is pressed down, and the left and right sets of joint pressing rollers move sequentially from the middle to both sides to connect and sew the carcass ply fabrics on both sides of the joint baffle.

[0080] The continuous tire carcass fabric that has completed the docking joint through the tire carcass joint device 18 is conveyed out of the joint position of the tire carcass unloading conveyor belt 19.

[0081] The tire carcass cord is inspected for quality via tire carcass inspection conveyor belt 20.

[0082] The tire carcass cord fabric undergoes a film application process via the tire carcass edge-wrapping device 21.

[0083] The completed tire carcass cord fabric from the adhesive film application process is wound into the tire carcass winding device 22.

[0084] The above completes the production of the 90-degree tire cord fabric.

[0085] When producing the 0-degree belt layer, the process flow before the reversing device 7 is the same, but it does not require subsequent cutting processes. Specifically, the production process of the steel wire cord fabric extrusion, adhesive coating, and cutting integrated machine also includes 0-degree belt layer winding, which includes:

[0086] The adhesive-coated belt layer, which is reversing the storage material via the reversing device 7, rotates to the direction of the 0-degree belt layer take-up device 23.

[0087] The 0-degree belt layer winding device 23 is equipped with four stations, which can simultaneously wind up the four 0-degree belt layers that have been extruded with adhesive.

[0088] The above completes the production of the 0-degree belt layer.

[0089] It should be noted that "multiple" in the above embodiments refers to at least two.
