Description

Technical Field

[0001] The invention relates to the technical field of ribbon ring processing, in particular to a ribbon ring device shared by multiple ribbons. Background Art

[0002] In modern industrial production, pipes are widely used in various fields as important basic components. In order to facilitate the identification of the purpose, specifications and correct connection of pipes, color stripes are usually painted on the surface of pipes. These color stripes not only serve as classification marks, but also provide important guidance for construction and installation. The traditional color stripe painting method mainly relies on manual application, which is not only inefficient, but also difficult to ensure the consistency of painting quality.

[0003] In order to improve production efficiency and product quality, the industry has developed an automated coating solution that adds ribbon rings to the mold. This method can complete the coating of the ribbon line while the pipe is extruded and formed, greatly improving production efficiency. However, with the continuous increase in the variety of pipeline products and the increasing diversification of market demand, the types and quantities of ribbon lines are also constantly changing. The existing ribbon ring device can usually only meet the coating needs of one or two ribbon lines. When more types of ribbon lines need to be coated, the ribbon ring must be replaced or reprocessed on the original basis, which not only increases production costs, but also seriously affects production efficiency and product delivery cycle. Frequent replacement or modification of ribbon rings may also lead to increased equipment downtime and reduced production line utilization; increase the labor intensity and skill requirements of operators; affect the stability of product quality, especially in the debugging stage after replacing the ribbon ring; and increase the difficulty of inventory management of raw materials and spare parts.

[0004] Therefore, the industry has proposed some solutions to the above problems. For example, the "Steel Tube Color Ribbon Color Ring Printing Equipment with Replaceable Color Material Color" disclosed in Chinese patent documents, with the announcement number "CN117507633A", proposes a four-color (white, cyan, magenta, and yellow) color matching mode, using two sets of dual-channel nozzles, the linear guide assembly is fixedly installed above the steel pipe, the gravity follower mounting plate is fixedly installed in the slider of the linear guide assembly, the nozzle assembly mounting plate is fixedly connected to the gravity follower mounting plate, the nozzle assembly is detachably installed in the nozzle assembly mounting plate, the curing assembly is connected to the nozzle assembly mounting plate, the gravity follower mounting plate above the nozzle assembly mounting plate is fixedly installed with a pressure wheel bearing seat and a pressure wheel, and the nozzle assembly mounting plate is arranged between the two pressure wheels; a steel pipe is placed below the nozzle assembly mounting plate, and the pressure wheel contacts the steel pipe.

[0005] Although the above scheme can provide 4 colors for color ring printing, which can effectively reduce the workload of on-site personnel and reduce paint waste, it is still necessary to disassemble and reassemble the nozzle when switching colors. This form will still seriously affect the production cycle in the actual production process. In view of the above situation, it is necessary to develop a ribbon ring device that can simultaneously meet the coating needs of multiple ribbon lines. Summary of the invention

[0006] In view of the shortcomings of the above-mentioned prior art, the present invention provides a ribbon ring device shared by multiple ribbons. This device can flexibly respond to the coating requirements of ribbon lines of different types and quantities, is easy to operate and adjust, reduces production line downtime, ensures the consistency and stability of coating quality, and has good compatibility, and is suitable for the production of pipes of different specifications.

[0007] In order to achieve the above object, the present invention adopts the following technical solutions: A ribbon ring device shared by multiple ribbons comprises: a ribbon ring having an outer cylindrical surface; at least two feed ports arranged on the outer cylindrical surface of the ribbon ring; a flow channel coaxially connected to the feed port; a sealing column arranged at a fork in the flow channel; and a sealing screw connected to the sealing column.

[0008] This ribbon ring device shared by multiple ribbons makes a single device multifunctional through structural optimization. The ribbon ring is a core component, and at least two feed ports arranged on its outer cylindrical surface allow different ribbon materials to be input simultaneously, thereby improving the applicability of the device. The flow channel system coaxially connected to the feed port guides different ribbon materials to the desired position, and realizes the switching of multiple ribbons through the sealing column arranged at the bifurcation of the flow channel. The sealing column can open or close a specific flow channel by adjusting the position of the plugging screw connected to it, thereby controlling the flow direction and combination of the ribbons. It not only simplifies the ribbon switching process, but also greatly shortens the switching time and improves production efficiency. Compared with the traditional method that requires replacing the entire ribbon ring, this solution can achieve different ribbon combinations by adjusting the position of the sealing column, greatly reducing downtime and mold replacement frequency. In addition, this solution also has good scalability, and the number of feed ports and flow channels can be increased as needed to adapt to more complex multi-ribbon requirements. In terms of material utilization, precise flow channel control also helps to reduce the waste of ribbon materials and reduce production costs.

[0009] Preferably, the flow channel comprises: a main flow channel; a branch flow channel connected to the main flow channel; and the sealing column is arranged at the intersection of the main flow channel and the branch flow channel.

[0010] Preferably, a single ribbon line flow channel is connected to feed port 1 among the feed ports; multiple ribbon line flow channels are connected to feed port 2 among the feed ports; and the single ribbon line flow channel and multiple ribbon line flow channels are respectively provided with independent sealing columns.

[0011] Preferably, the single ribbon line outlet connected to the single ribbon line flow channel; the multiple ribbon line outlets connected to the multiple ribbon line flow channels; each single ribbon line outlet and each multiple ribbon line outlet are arranged in the same cylindrical surface.

[0012] Preferably, the multiple ribbon line outlets include: a dual-ribbon outlet, disposed at a branch end of the multiple ribbon line flow channel; and a quad-ribbon outlet, disposed at another branch end of the multiple ribbon line flow channel.

[0013] Preferably, the sealing column is adjustable in position and can move within the flow channel.

[0014] Preferably, the sealing screw is threadably connected to the ribbon ring, and the position of the sealing column can be adjusted by rotation.

[0015] Preferably, a mounting structure for fixing is also provided on the outer cylindrical surface of the ribbon ring.

[0016] Preferably, the multiple ribbon line flow channels include: a main flow channel directly connected to the feed port; a branch flow channel vertically connected to the main flow channel; and the sealing column is arranged at the intersection of the main flow channel and the branch flow channel.

[0017] Preferably, the branch flow channel includes: a two-color ribbon flow channel connected to the two-color ribbon outlet; a four-color ribbon flow channel connected to the four-color ribbon outlet; a single-root multiple-ribbon flow channel connected to the single-root multiple-ribbon outlet; each of the branch flow channels is provided with an independent sealing column.

[0018] Therefore, the present invention has the following beneficial effects: The multi-ribbon shared ribbon ring device can flexibly adjust the sealing column position to achieve multiple ribbon coating functions of a single device, greatly improving production flexibility and efficiency, significantly shortening ribbon switching time, and effectively reducing production costs.

[0019] The innovative flow channel design and sealing column system make the ribbon material flow more uniform and stable, reduce dead corners and deposition problems, improve the quality and consistency of ribbon coating, and help improve product quality.

[0020] The modular design facilitates equipment maintenance and cleaning, reduces downtime and maintenance costs, while increasing equipment life and optimizing economic benefits.

DETAILED DESCRIPTION

[0029] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions.

[0030] Example 1 like Figure 1 , 2 As shown, this embodiment describes in detail a ribbon ring device shared by multiple ribbons, which includes key components such as a ribbon ring 1, a feed port, a flow channel, a sealing column, and a sealing screw. The ribbon ring has an outer cylindrical surface, and at least two feed ports are arranged on its surface, and these feed ports are coaxially connected to the flow channel. The flow channel system includes a main flow channel 3 and a branch flow channel 2 connected thereto, and a sealing column is arranged at the intersection of the main flow channel 3 and the branch flow channel 2. The sealing column is connected to the ribbon ring through a sealing screw, and the position can be adjusted in the flow channel.

[0031] like Figure 3 , 4As shown in Figures 5 and 6, the flow channel system also includes a single ribbon line flow channel and multiple ribbon line flow channels, which are respectively connected to different feed ports. The single ribbon line flow channel is connected to the single ribbon line outlet, and the multiple ribbon line flow channel is connected to the multiple ribbon line outlets. These outlets are all arranged on the outer cylindrical surface of the ribbon ring to form a cylindrical outlet surface. The multiple ribbon line outlets include a double ribbon outlet 5 and a four ribbon outlet 4, which are respectively located at the two branch ends of the multiple ribbon line flow channels. Feed port 1 8 and feed port 2 9 are coaxially symmetrically arranged on the ribbon ring, which is conducive to maintaining the uniformity and stability of ribbon coating. The branch flow channel 2 system includes a double ribbon flow channel, a four ribbon flow channel and a single multiple ribbon flow channel, which are respectively connected to the corresponding outlets. Each branch flow channel 2 is equipped with an independent sealing column, which can accurately control the flow of different ribbons. The adjustability of the sealing column enables the operator to flexibly adjust the opening and closing state of the flow channel according to different ribbon coating requirements. The threaded connection between the sealing screw and the ribbon ring can achieve precise adjustment of the sealing column position by rotation, which can not only ensure the accuracy of adjustment, but also improve the convenience of operation. The fixed mounting structure on the outer cylindrical surface of the ribbon ring ensures the stability of the entire device during use. This multifunctional integrated solution significantly improves the flexibility and efficiency of ribbon coating, and can achieve a variety of coating requirements such as single color, two-color, and four-color on the same device, greatly reducing production line downtime and mold replacement frequency. By adding flow channel branches and discharge ports, more combined coating of ribbons can also be achieved. In addition, the sealing column system also reserves interfaces for future intelligent control, and can achieve automatic adjustment and real-time monitoring by adding electric actuators or sensors.

[0032] Specifically, the ribbon ring device shared by multiple ribbons is mainly composed of a ribbon ring, a flow channel system, a sealing column system and a sealing screw. The various components cooperate with each other to form a fully functional ribbon coating system.

[0033] The ribbon ring is the basic structure of the entire device. It is cylindrical with a smooth outer surface and is made of corrosion-resistant and wear-resistant metal or engineering plastic. There are multiple functional openings on the outer cylindrical surface of the ribbon ring, including a feed port and a discharge port. There are two feed ports, namely feed port 1 8 and feed port 2 9, which are symmetrically distributed on the outer cylindrical surface of the ribbon ring to ensure the balance and stability of material input.

[0034] The flow channel system is the core structure inside the ribbon ring, which consists of the main channel 3 and the branch channel 22. The main channel extends from the feed port to the inside of the ribbon ring, in a straight line or arc shape, and its diameter should match the feed port to ensure smooth material flow. The branch channel 2 branches out from the main channel to form a complex network structure. The cross-section of these channels is circular or elliptical to reduce flow resistance. The inner wall of the channel is smoothed to reduce friction and improve wear resistance.

[0035] like Figure 6As shown, the sealing column system is a key component for achieving multi-color ribbon sharing. A plurality of sealing columns are arranged at the bifurcation of the flow channel, including a four-color ribbon flow channel sealing column 2-1, a two-color ribbon flow channel sealing column 2-2, a single multi-color ribbon flow channel sealing column 7-2 and a main flow channel sealing column 7-3. These sealing columns are cylindrical or conical, and the material should have good sealing and wear resistance. The diameter of the sealing column is slightly smaller than the flow channel diameter so that it can move freely in the flow channel. The sealing screw 11 is connected to the sealing column 11-1 and cooperates with the sealing column screw hole 10 on the ribbon ring through a thread. The material of the screw is stainless steel or other anti-corrosion materials, and the thread precision is high to ensure the accuracy of the adjustment. The screw head adopts a shape suitable for tool operation, such as a hexagon or a cross.

[0036] The discharge port system includes a single-color ribbon discharge port 6, a double-color ribbon discharge port 5, a four-color ribbon discharge port 4, and a single-ribbon multiple-ribbon discharge port 7. These discharge ports are evenly distributed on the outer cylindrical surface of the ribbon ring to form a circular array, in which the main port 7-1 of the single-ribbon multiple-ribbon discharge port is symmetrically arranged relative to the single-color ribbon discharge port 6. The size and shape of each discharge port vary according to its function, but they all match the corresponding flow channel. By adjusting the sealing columns at different positions, the flow direction of the material in the flow channel can be changed, thereby achieving the coating requirements of single-color, double-color, four-color or even more ribbons. For example, when a double-color ribbon is required, the corresponding flow channel can be opened by adjusting the double-color ribbon flow channel sealing column 2-2; when a four-color ribbon is required, the four-color ribbon flow channel sealing column 2-1 can be adjusted. This solution can effectively reduce the downtime of the production line and the frequency of mold replacement, thereby improving production efficiency.

[0037] In addition, considering that the ribbon contains various chemical components, all surfaces in contact with the ribbon should have good corrosion resistance and chemical stability. At the same time, considering frequent adjustments and use, these parts should also have good mechanical strength and wear resistance. Optional materials include but are not limited to stainless steel, special engineering plastics or surface-treated aluminum alloys. The design of the flow channel should take into account the rheological properties of the ribbon material. The cross-sectional area, turning radius and other parameters of the flow channel should be accurately calculated to ensure that the ribbon material maintains a stable flow rate and pressure during the flow process to avoid local blockage or uneven flow.

[0038] In actual application, the operation process of the ribbon ring device shared by multiple ribbons in this embodiment is as follows: First, the operator needs to determine the type and quantity of ribbons required according to production requirements. Then, the specific flow channel is opened or closed by adjusting the corresponding sealing column. For example, if two ribbons are required, the two-ribbon flow channel sealing column 2-2 is adjusted; if four ribbons are required, the four-ribbon flow channel sealing column 2-1 is adjusted. During the adjustment process, the operator needs to use an appropriate tool to rotate the sealing screw 11 so that the sealing column 11-1 moves to a suitable position in the flow channel.

[0039] During installation, first fix the ribbon ring 1 on the mold, making sure that its outer cylindrical surface is flush with the mold surface. Then, connect the feed ports 8 and 9 to the ribbon supply system. Pay attention to the sealing when connecting to prevent the ribbon material from leaking. Next, adjust the position of each sealing column according to production requirements. When adjusting, be careful not to over-tighten the sealing screws to avoid damaging the threads or affecting the movement of the sealing column.

[0040] When in use, the ribbon material enters from the feed port 8 or 9, and is distributed to each branch channel 22 through the main channel 3. Depending on the position of the sealing column, the ribbon material will flow to different outlets. For example, when a single-color ribbon is required, the ribbon material enters from the feed port 8 and flows directly to the single-color ribbon outlet 6. When a double-color ribbon is required, the ribbon material enters from the feed port 9, passes through the main channel 3 and the corresponding branch channel 22, and finally flows out from the double-color ribbon outlet 5.

[0041] During the production process, the tightness of the sealing column and the sealing screw should be checked regularly to prevent loosening due to vibration. Secondly, monitor the flow of the ribbon material. If abnormalities are found, adjust the position of the sealing column or clean the flow channel in time. Thirdly, according to the characteristics of different ribbon materials, the temperature or pressure of the flow channel needs to be adjusted to ensure the fluidity and adhesion of the ribbon material.

[0042] In this embodiment, the preferred solution may consider adding an electric control device to the sealing column system to achieve automatic adjustment. This improvement can be achieved by adding a micro motor and a sensor in conjunction with a control system. For example, a pressure sensor may be installed in the flow channel to monitor the flow state of the ribbon material in real time. When an abnormality is detected, the control system may automatically adjust the sealing column position.

[0043] It is worth noting that the key to this device lies in the design of the flow channel system. The cross-sectional area and shape of the flow channel directly affect the flow characteristics of the ribbon material, and the optimal flow channel diameter and turning radius can be calculated. For example, assuming that the viscosity of the ribbon material is η, the flow velocity is v, and the flow channel diameter is d, the Reynolds number Re = ρvd / η (where ρ is the density) can be used to judge the flow state and optimize the flow channel design.

[0044] In practical applications, the device may also face challenges such as the deposition of ribbon materials in the flow channel. To solve this problem, this embodiment adds a special coating, such as a polytetrafluoroethylene (PTFE) coating, inside the flow channel to reduce friction and deposition. In addition, a regular cleaning mechanism is designed, such as using a specific solvent to regularly flush the flow channel system. In addition, considering that the ribbon material may contain various chemical components, the ribbon ring material needs to have good corrosion resistance and chemical stability. High-performance engineering plastics such as polyetheretherketone (PEEK) or polyphenylene sulfide (PPS) can be considered, which have excellent mechanical properties and chemical stability.

[0045] In production practice, the use of this device may significantly improve production efficiency. Take a typical pipe production line as an example. Assuming that it takes 30 minutes to replace the ribbon ring, it only takes 5 minutes to adjust the sealing column position using this device. If the ribbon type needs to be changed 5 times a day, 125 minutes of production time can be saved every day. This not only improves production capacity, but also reduces product quality fluctuations caused by frequent downtime.

[0046] In addition, technicians in this field can further transform the manually adjusted sealing column system into an electric or pneumatic control system, and cooperate with sensors and controllers to achieve automatic adjustment and real-time monitoring. This upgrade can not only further improve production efficiency, but also achieve more precise ribbon control to meet higher-end production needs.

[0047] Example 2 This embodiment proposes an improved multi-ribbon shared ribbon ring device, which adopts a modular design concept to divide the ribbon ring into multiple detachable fan-shaped units. Each fan-shaped unit includes an independent feed port, flow channel system and discharge port, which are combined into a complete ring structure through a precise connection mechanism. This solution can effectively improve the flexibility and maintainability of the device.

[0048] The ribbon ring is composed of 6-8 sector units, each covering a central angle of 45°-60°. The units are connected by a slot-type connection, and the sealing ring is used to ensure the sealing of the connection. A feed port is provided on the outer wall of each sector unit, and a main channel and multiple branch channels 2 are designed inside. The main channel extends radially, and the branch channels 2 are distributed in a tree shape, and the material flow direction is controlled by an adjustable micro valve.

[0049] The flow channel system adopts a "gradient flow channel" structure. The diameter of the main channel gradually decreases from the feed port to the inside to maintain a stable flow rate; the branch flow channel 2 adopts a capillary-like structure with a diameter of only 0.5-1mm, and uses the surface tension effect to achieve precise control. The inner wall of the flow channel adopts a special hydrophobic coating, such as polytetrafluoroethylene (PTFE) or fluorinated polymer to reduce the adhesion of the ribbon material. Each branch flow channel 2 intersection is equipped with a micro ball valve with a diameter of only 2-3mm and made of high-precision ceramic material. The valve is controlled by a micro stepper motor and can achieve precise adjustment of 0.1°. It not only improves the adjustment accuracy, but also greatly reduces the size of the device.

[0050] The discharge port is also optimized compared to Example 1. Multiple discharge ports are provided on the outer edge of each sector unit, and a retractable nozzle is used. The nozzle is made of memory alloy, and the diameter and length can be automatically adjusted as needed to meet the requirements of ribbons of different widths and thicknesses. The control system adopts a distributed architecture, and each sector unit is equipped with an independent microcontroller, which communicates with the central controller through the CAN bus. This design improves the response speed and reliability of the system. The control software adopts a fuzzy logic algorithm, which can automatically adjust the configuration of the flow channel and valve according to parameters such as the viscosity and temperature of the ribbon material. The main body of the sector unit is made of corrosion-resistant titanium alloy, which is light in weight and high in strength. The inner wall of the flow channel is treated with nano-level smoothness, and the surface roughness reaches Ra0.01μm, which effectively reduces the deposition of the ribbon material. The sealing ring is made of fluororubber material with a temperature range of -40°C to 250°C, which can adapt to various working environments.

[0051] The characteristics of this embodiment are modularity and customizability. Users can choose different numbers and configurations of fan-shaped units according to their needs, and easily achieve a combination of 2-8 ribbons. The detachable design of the unit also effectively simplifies cleaning and maintenance. By increasing the number of fan-shaped units, more combinations of ribbons can be achieved, but the balance between the overall structural strength and sealing needs to be considered.

[0052] In practical applications, this device can significantly improve production efficiency. For example, assuming that it takes 30 minutes to replace the ribbon in the traditional way, this design only takes 5 minutes to adjust the valve configuration. If the average number of changes is 5 times a day, 125 minutes of production time can be saved every day. In addition, the modular design also reduces spare parts inventory costs and improves equipment availability.

[0053] It is particularly noteworthy that the gradient flow channel design ensures that the ribbon material maintains a stable shear rate during the flow process, avoiding the "dead zone" problem common in traditional designs. By calculating the Reynolds number Re = ρvd / η (where ρ is density, v is flow velocity, d is pipe diameter, and η is viscosity), the flow state of each flow channel section can be accurately controlled to ensure laminar flow conditions, thereby improving the uniformity of ribbon coating.

[0054] In actual application, the operation process of the multi-ribbon shared ribbon ring device is as follows: First, the operator needs to select the appropriate number and configuration of fan-shaped units according to production requirements, usually 6-8. During installation, the fan-shaped units are snapped together in sequence, and the sealing rings are properly positioned to ensure the sealing of the overall structure. After the connection is completed, use a special tool to check the tightness of each connection to ensure that there is no risk of leakage.

[0055] Before use, the flow channel configuration of each sector unit needs to be preset according to the production plan. This includes adjusting the opening of the micro ball valve and the shape of the nozzle. The adjustment process is carried out through the central control system. The operator only needs to enter the required ribbon combination, and the system will automatically calculate and set the optimal flow channel and valve configuration. For example, if two ribbons are required, the system will select two adjacent sector units and close the outlet of the other units.

[0056] At the beginning of production, the ribbon material is input from the feed port of each sector unit. Thanks to the gradient flow channel design, the material maintains a stable shear rate during the flow process. Assuming that the viscosity of the ribbon material is 100 mPa·s, the flow rate is 0.5 m / s, and the main channel diameter gradually decreases from 3mm to 1mm, the Reynolds number Re decreases from 150 to 50, and always remains in a laminar state, ensuring the uniformity of ribbon coating.

[0057] The micro ball valve is precisely controlled by the control system, and each ball valve is controlled by an independent stepper motor, which can achieve precise adjustment of 0.1°. That is, in the branch flow channel 2 with a diameter of 0.5mm, the flow rate can be precisely controlled to 0.0001mm³, thereby achieving micron-level ribbon thickness adjustment.

[0058] During the production process, the system monitors the pressure and temperature of each flow channel in real time. If an abnormality is detected, such as a sudden increase in pressure in a flow channel, which may indicate a risk of blockage, the system will automatically adjust the corresponding ball valve opening or start a backup flow channel to ensure production continuity.

[0059] After use, according to the automatic cleaning program designed by the system, a specific solvent is injected into the flow channel and a pulse flow is generated by the rapid switching of the micro ball valve to effectively remove the residual ribbon material. The choice of cleaning solvent needs to be determined according to the characteristics of the ribbon material, and organic solvents with low surface tension, such as ethanol or isopropanol, are usually used.

[0060] During routine maintenance, thanks to the modular design, individual sector units can be easily removed for deep cleaning or replacement.

[0061] In actual production, this solution can significantly improve production efficiency and flexibility. For example, on a typical pipe production line, the traditional replacement of ribbon configuration may require 30 minutes of downtime, while this device only takes 5 minutes to reconfigure the system. Assuming that the ribbon combination needs to be replaced 5 times a day, 125 minutes of production time can be saved every day. In addition, since different ribbon combinations can be quickly switched, companies can arrange small batches and multiple varieties of production more flexibly and improve market response speed. Traditional ribbon replacement often produces a certain amount of waste materials. This device can minimize material waste through precise control. Assuming that each replacement will produce 100g of waste materials, 5 replacements a day, about 180kg of ribbon materials can be saved in a year, which not only reduces costs but also reduces environmental impact.

[0062] Furthermore, those skilled in the art may consider adding an online viscosity monitoring device to the system. By real-time monitoring of the viscosity changes of the ribbon material, the system can automatically adjust the configuration of the flow channel and valve to adapt to the slight differences between different batches of materials, further improving the consistency of ribbon coating.
