Abstract
Description
Technical Field
[0001] The invention relates to the technical field of rubber pipeline molding, and in particular to an extruded fluorosilicone oil-resistant pipeline rubber hose and a molding device. Background Art
[0002] Fluorosilicone oil-resistant pipeline hoses are mainly composed of an inner rubber layer, a reinforcement layer and an outer rubber layer. The inner rubber layer is traditionally made of fluororubber. Fluororubber has excellent oil resistance due to the introduction of fluorine atoms in the main chain and side chain. Its good elasticity and softness can adapt to fluid pressure and reduce oil flow resistance. For example, it can be flexibly arranged in the fuel delivery system of automobile engines and resist fuel corrosion. However, the synthesis process of fluororubber is complicated and expensive. The use of fluorosilicone in the inner rubber layer increases the product cost.
[0003] At present, rubber pipe extruders generally use spiral conveying to extrude rubber. Its working principle is to rely on the continuous rotation of the screw to gradually push the rubber material from the hopper to the head of the extruder. However, in the actual working process, it is often encountered that the quality of the produced rubber pipe does not meet the requirements due to insufficient feeding at the feed port. From the appearance point of view, insufficient feeding is likely to make the surface of the rubber pipe uneven, with defects such as depressions or protrusions. From the perspective of the internal structure of the rubber pipe, insufficient feeding will cause the problem of inconsistent pipe wall thickness.
[0004] Once the rubber pipes used in industrial equipment have quality problems, the consequences may be very serious. For example, when the pipe wall thickness is inconsistent or there are defects on the surface, it is very likely that the medium will leak. This will directly affect the normal operation of the entire industrial equipment, and may cause equipment failure, production stagnation, and even in some special environments (such as chemical production involving corrosive media) It may cause serious consequences such as safety accidents.

[0016] The working principle and beneficial effects of the present invention are: In the present invention, in order to solve the problem of insufficient feeding of the extruder for fluorosilicone oil-resistant pipeline hose in the related art, resulting in unstable product quality, an extruded fluorosilicone oil-resistant pipeline hose molding device is designed. It includes a device body, a feed funnel and a tamping plate. The device body, as the main structure of the entire molding device, has a first feed port for receiving the fluorosilicone material delivered from the feed funnel. The feed funnel is arranged on the device body, and has a second feed port and a first discharge port. The second feed port is the entrance of the fluorosilicone material, and the material enters the feed funnel from here.

[0017] The pounding plate is slidably arranged in the feed hopper, and the pounding plate has a pounding part. In actual operation, after the fluorosilicone material enters the feed hopper from the second feed port, the pounding plate can slide. When the pounding plate slides in the direction close to the first discharge port, the pounding part can squeeze and push the material that is about to enter the first discharge port, ensuring that the material can enter the device body continuously and evenly. When the material is accumulated or blocked in the feed hopper, the sliding of the pounding plate can effectively push the material to the first discharge port, avoiding discontinuous and insufficient feeding.
[0018] The advantage is that by setting up a tamping plate, it is possible to deal with the possible accumulation or blockage of materials in the feed funnel in time, ensuring that the material can continuously and stably enter the device body from the feed funnel. This is crucial for the production of extruded fluorosilicone oil-resistant pipeline hoses, because continuous and uniform feeding is one of the key factors to ensure the stability of hose quality. In actual production, after using this device, the surface defects of the hose caused by discontinuous feeding, such as depressions and protrusions, can be effectively reduced, and the appearance quality of the product can be improved. Since the continuity and uniformity of the feed are guaranteed, the production interruption and adjustment time caused by feeding problems are reduced, thereby improving the production efficiency of the entire extruded fluorosilicone oil-resistant pipeline hose. At the same time, stable feeding also helps to reduce the scrap rate and reduce production costs. BRIEF DESCRIPTION OF THE DRAWINGS

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0024] In addition, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.
[0025] Reference Figure 1~Figure 5, which is the first embodiment of the present invention, proposes an extruded fluorosilicone oil-resistant pipeline hose forming device, including a device body 1, the device body 1 has a first feed port 101; a feed funnel 2 has a second feed port 201 and a first discharge port 202, the feed funnel 2 is arranged on the device body 1, and the first discharge port 202 is connected to the first feed port 101; a pounding plate 3 is slidably arranged in the feed funnel 2, the pounding plate 3 has a pounding part 301, after the pounding plate 3 slides, the pounding part 301 approaches or moves away from the first discharge port 202.
[0026] In this embodiment, in order to solve the problem of insufficient feeding of the extruder for fluorosilicone oil-resistant pipeline hose in the related art, resulting in unstable product quality, an extruded fluorosilicone oil-resistant pipeline hose molding device is designed. It includes a device body 1, a feed funnel 2 and a pounding plate 3. The device body 1, as the main structure of the entire molding device, has a first feed port 101 for receiving the fluorosilicone material delivered from the feed funnel 2. The feed funnel 2 is arranged on the device body 1, and has a second feed port 201 and a first discharge port 202. The second feed port 201 is the entrance of the fluorosilicone material, and the material enters the feed funnel 2 from here. The first discharge port 202 is connected to the first feed port 101 of the device body 1, so that the material can smoothly enter the device body 1 from the feed funnel 2 for subsequent molding processing.
[0027] The pounding plate 3 is slidably disposed in the feed hopper 2, and the pounding plate 3 has a pounding portion 301. In actual operation, after the fluorosilicone material enters the feed hopper 2 from the second feed port 201, the pounding plate 3 can slide. When the pounding plate 3 slides in the direction close to the first discharge port 202, the pounding portion 301 can squeeze and push the material that is about to enter the first discharge port 202, ensuring that the material can continuously and evenly enter the device body 1. When the material is accumulated or blocked in the feed hopper 2, the sliding of the pounding plate 3 can effectively push the material to the first discharge port 202 to avoid discontinuous feeding.
[0028] The advantage is that by setting the tamping plate 3, the possible accumulation or blockage of materials in the feed hopper 2 can be dealt with in time, ensuring that the material can continuously and stably enter the device body 1 from the feed hopper 2. This is crucial for the production of extruded fluorosilicone oil-resistant pipeline hoses, because continuous and uniform feeding is one of the key factors to ensure the stability of hose quality. In actual production, after adopting this device, the surface defects of the hose caused by discontinuous feeding, such as depressions, protrusions, etc., can be effectively reduced, thereby improving the appearance quality of the product. Since the continuity and uniformity of the feed are guaranteed, the production interruption and adjustment time caused by feeding problems are reduced, thereby improving the production efficiency of the entire extruded fluorosilicone oil-resistant pipeline hose. At the same time, stable feeding also helps to reduce the scrap rate and reduce production costs.
[0029] Furthermore, there are two pounding plates 3, one side of the two pounding plates 3 is respectively slidably set on the two opposite inner walls of the feed funnel 2, and the other side of the pounding plates 3 has a plurality of guide sleeves 302, and also includes a sliding column 4, the sliding column 4 is vertically slidably set in the feed funnel 2, the sliding column 4 has a plurality of sliding rods 401, and the plurality of sliding rods 401 are respectively slidably set in different guide sleeves 302. After the sliding column 4 slides, the two pounding plates 3 are driven to slide.
[0030] In this embodiment, two pounding plates 3 are provided, and one side of the two pounding plates 3 is respectively slidably arranged on two opposite inner walls of the feed hopper 2. The other side of each pounding plate 3 has a plurality of guide sleeves 302. At the same time, a sliding column 4 is also included. The sliding column 4 is vertically slidably arranged in the feed hopper 2, and the sliding column 4 has a plurality of sliding rods 401, and these sliding rods 401 are respectively slidably arranged in different guide sleeves 302.
[0031] During operation, when the sliding column 4 slides up and down, the two tamping plates 3 will slide relative to each other on the inner wall of the feeding funnel 2 due to the matching relationship between the sliding rod 401 and the guide sleeve 302. When the sliding column 4 slides downward, the two tamping plates 3 approach each other and move toward the first discharge port 202 to squeeze and push the material; when the sliding column 4 slides upward, the two tamping plates 3 move away from each other to make room for new materials.
[0032] The advantage is that the two ramming plates 3 can squeeze and push the material from two opposite directions, making the material more evenly distributed in the feed hopper 2, further improving the uniformity and continuity of the feed. The two ramming plates 3 can move synchronously through the cooperation of the sliding column 4 and the sliding rod 401 with the guide sleeve 302, thereby ensuring the stability of the device during operation. This design can avoid the uneven force or unstable movement that may occur in a single ramming plate 3, and reduce the wear and failure rate of the device.
[0033] Furthermore, the sliding column 4 has a first abutment portion 402 at one end away from the first discharge port 202, and also includes a first rotating disk 5. The first rotating disk 5 has a plurality of first abutment surfaces 501. The plurality of first abutment surfaces 501 are evenly distributed along the circumference of the axis of the first rotating disk 5 and are connected end to end. The two ends of the first abutment surface 501 are respectively a starting point and an end point. The starting point is higher than the end point. After the first rotating disk 5 rotates, the first abutment portion 402 passes through the starting points and end points of the plurality of first abutment surfaces 501 in sequence. There are a plurality of elastic members 6, and the two ends of the elastic members 6 are respectively abutted against the feed funnel 2 and the pounding plate 3, so as to provide a force to keep the pounding plate 3 away from the first discharge port 202.
[0034] In this embodiment, the sliding column 4 has a first abutment portion 402 at one end close to the first discharge port 202. A first rotating disk 5 is provided, and the first rotating disk 5 has a plurality of first abutment surfaces 501, which are evenly distributed along the circumference of the axis of the first rotating disk 5 and connected end to end. The two ends of the first abutment surface 501 are respectively a starting point and an end point, and the starting point is lower than the end point. When the first rotating disk 5 rotates, the first abutment portion 402 passes through the starting points and end points of the plurality of first abutment surfaces 501 in sequence.
[0035] At the same time, a plurality of elastic members 6 are also provided, and the two ends of the elastic members 6 are respectively in contact with the feed hopper 2 and the pounding plate 3. In actual operation, when the first rotating disk 5 rotates, its first abutting surface 501 pushes the first abutting portion 402 to move downward, and the sliding column 4 slides downward, driving the two pounding plates 3 to approach each other through the sliding rod 401, and the elastic member 6 is compressed at this time. When the end point of the first abutting surface 501 rotates away from the first abutting portion 402, under the action of the restoring force of the elastic member 6, the pounding plate 3 moves away from the first discharge port 202, and the sliding column 4 slides upward.
[0036] The first rotating disk 5 is driven by a motor to rotate at a stable speed. As the first rotating disk 5 rotates, the first abutting portion 402 continuously rises and falls on different first abutting surfaces 501 , thereby achieving the periodic movement of the pounding plate 3 approaching and moving away from the first discharge port 202 .
[0037] The advantage is that, through the cooperation of the first rotating disk 5 and the elastic member 6, the automatic reciprocating motion of the tamping plate 3 can be achieved without additional manual intervention, thereby improving the degree of automation of production. This not only reduces labor costs, but also improves production efficiency and ensures the continuity and stability of the feeding process. In the continuous production process, the device can automatically perform tamping operations on the materials in the feeding funnel 2 without the need for frequent adjustments and operations by the operator, which greatly reduces the labor intensity. The shape of the first abutting surface 501 and the elastic coefficient of the elastic member 6 can be designed and adjusted according to actual needs, thereby achieving precise control of the tamping force.
[0038] Furthermore, it also includes a first mounting frame 7, which is arranged on the device body 1; a first driving member 8 is arranged on the first mounting frame 7, and the output end of the first driving member 8 is located in the feeding funnel 2, which is used to drive the first rotating disk 5 to rotate.
[0039] In this embodiment, a first mounting frame 7 and a first driving member 8 are provided. The first mounting frame 7 is installed on the device body 1, and plays the role of supporting and fixing the first driving member 8. The first driving member 8 is arranged on the first mounting frame 7, and its output end is located in the feeding funnel 2, and is used to drive the first rotating disk 5 to rotate.
[0040] The advantage is that the first mounting frame 7 provides a firm mounting position for the first driving member 8, ensuring that the first driving member 8 will not shake or shift during operation, thereby being able to stably drive the first rotating disk 5 to rotate. The first driving member 8 can be used to conveniently adjust the rotation speed of the first rotating disk 5, thereby controlling the movement frequency and pounding force of the pounding plate 3. The first driving member 8 is used to drive the first rotating disk 5, thereby realizing the automatic operation of the device, reducing manual intervention, and improving production efficiency.
[0041] Furthermore, the sliding column 4 also has a first guide groove 403 , and also includes a guide rod 9 , one end of the guide rod 9 is arranged on the inner wall of the feed funnel 2 , and the other end is slidably arranged in the first guide groove 403 .
[0042] In this embodiment, the sliding column 4 has a first guide groove 403. At the same time, there is a guide rod 9, one end of which is fixedly arranged on the inner wall of the feeding funnel 2, and the other end is slidably arranged in the first guide groove 403.
[0043] In actual operation, when the sliding column 4 is driven by the first rotating disk 5 to move vertically, the guide rod 9 will slide accordingly in the first guide groove 403. If the first guide groove 403 is a vertical straight groove, the guide rod 9 will move up and down along the straight groove, ensuring that the sliding column 4 can only move up and down in a straight line without shaking or tilting left and right.
[0044] The advantage is that the cooperation between the guide rod 9 and the first guide groove 403 can effectively limit the movement direction of the sliding column 4, ensuring that the sliding column 4 can only move along the predetermined vertical direction. This is very critical for the stable operation of the entire tamping system, because if the movement direction of the sliding column 4 is unstable, the tamping plate 3 will not be able to accurately process the material, and the material may accumulate or be processed unevenly.
[0045] Furthermore, the inner wall of the feed funnel 2 also has a ball head protrusion 203, and also includes a second mounting frame 10, one end of which is arranged on the feed funnel 2; a limiting ring 11 is arranged at the other end of the second mounting frame 10; one end of the screening barrel 12 has a ball head groove 1202, the ball head protrusion 203 and the ball head groove 1202 form a ball joint pair, and the other end of the screening barrel 12 has a contact ring 1201, and the other end of the screening barrel 12 is swingably set in the limiting ring 11, and one side of the contact ring 1201 is contacted with the upper surface of the limiting ring 11.
[0046] In this embodiment, a ball head protrusion 203 is provided on the inner wall of the feed funnel 2. A second mounting frame 10 is also provided, one end of which is fixed on the feed funnel 2, and a limiting ring 11 is installed on the other end of the second mounting frame 10. There is a screening barrel 12, one end of which has a ball head groove 1202, and the ball head groove 1202 forms a ball joint with the ball head protrusion 203 on the inner wall of the feed funnel 2, and the other end of the screening barrel 12 has an abutting ring 1201, which is swingably set in the limiting ring 11, and one side of the abutting ring 1201 abuts against the upper surface of the limiting ring 11.
[0047] During the production process, the material first reaches the screening barrel 12. The screening barrel 12 is designed with sieve holes of a specific size. When the material passes through the screening barrel 12, only particles that meet the size requirements can pass through the sieve holes and enter the next process. For example, for fluorosilicone raw materials, if the particle size is required to be within a specific range, particles larger or smaller than this range will be retained in the screening barrel 12, while particles that meet the size requirements will pass smoothly and enter the subsequent processing links.
[0048] The advantage is that the screening barrel 12 screens the particle size of the feed material through its sieve hole design to ensure that the particle size of the material entering the subsequent processing link is uniform. In this way, during the extrusion of the fluorosilicone oil-resistant pipeline hose, the force of each part and the distribution of the material during the molding process are more uniform, thereby improving the quality stability of the product. Since the screening barrel 12 strictly controls the size of the feed particles, product quality problems that may be caused by uneven particle size are avoided.
[0049] Furthermore, it also includes a rotating ring 13, which is rotatably set outside the limiting ring 11; the abutment wheel 14 is rotatably set on the rotating ring 13, and the abutment wheel 14 abuts against the abutment ring 1201, so that one side of the abutment ring 1201 abuts against the limiting ring 11.
[0050] In this embodiment, a rotating ring 13 and an abutting wheel 14 are provided. The rotating ring 13 is rotatably arranged outside the limiting ring 11 , and the abutting wheel 14 is rotatably arranged on the rotating ring 13 .
[0051] In the actual production process, the screening barrel 12 needs to effectively screen the materials and needs to change its angle to screen the materials of different particle sizes. When the angle of the screening barrel 12 needs to be adjusted for screening, the rotating ring 13 is rotated, and the abutting wheel 14 moves along with the rotation of the rotating ring 13. Since the abutting wheel 14 abuts against the abutting ring 1201 of the screening barrel 12, the abutting wheel 14 will push the abutting ring 1201, so that the screening barrel 12 swings around the ball head protrusion 203.
[0052] The advantage is that the screening barrel 12 is pushed to swing by the cooperation of the rotating ring 13 and the abutting wheel 14, so that the screening barrel 12 can perform screening operations during the rotation process, thereby realizing flexible screening of materials with different particle sizes.
[0053] Furthermore, the output end of the first driving member 8 also has a first gear tooth, and the outer side of the rotating ring 13 has a second gear tooth, and the first gear tooth meshes with the second gear tooth.
[0054] In this embodiment, the output end of the first driving member 8 has a first gear tooth, the outer side of the rotating ring 13 has a second gear tooth, and the first gear tooth and the second gear tooth are meshed with each other.
[0055] In actual operation, when the first driving member 8 starts to work, the first gear teeth at the output end thereof start to rotate. Since the first gear teeth are meshed with the second gear teeth on the outer side of the rotating ring 13, the rotating ring 13 will also rotate accordingly.
[0056] The advantage is that the power of the first driving member 8 is transmitted to the rotating ring 13 through the meshing of the first gear teeth and the second gear teeth, so that the driving of the first rotating disk 5 by the first driving member 8 and the rotation of the rotating ring 13 are linked. In this way, during the production process, one power source (the first driving member 8) can simultaneously control the movement of the pounding plate 3 and the adjustment of the angle of the screening barrel 12, simplifying the driving system of the device.
[0057] Furthermore, it also includes a plurality of limiting wheels 15 , which are all rotatably arranged on the second mounting frame 10 , and are all in contact with the lower surface of the rotating ring 13 to prevent the rotating ring 13 from falling off.
[0058] In this embodiment, in the extruded fluorosilicone oil-resistant pipeline hose forming device, a plurality of limiting wheels 15 are provided. These limiting wheels 15 are all rotatably arranged on the second mounting frame 10, and all the limiting wheels 15 are in contact with the lower surface of the rotating ring 13.
[0059] In actual operation, when the rotating ring 13 rotates, the rotating ring 13 will be restricted within a certain space due to the presence of the limiting wheel 15. For example, when the rotating ring 13 tends to jump upward due to the vibration of the equipment or other external factors, the limiting wheel 15 will press against the lower surface of the rotating ring 13 to prevent it from moving upward, ensuring that the rotating ring 13 always runs stably at the designed position.
[0060] The advantage is that the setting of the limiting wheel 15 can effectively prevent the rotating ring 13 from positional deviation during operation, especially upward jumping. This is crucial to ensure the normal operation of the entire device, because the positional stability of the rotating ring 13 is directly related to the stability of the abutment of the abutment wheel 14 on the screening barrel 12, thereby affecting the working effect of the screening barrel 12. By limiting the position of the rotating ring 13, the probability of mechanical failure caused by the unstable position of the rotating ring 13 is reduced. This allows the entire device to operate more reliably during a long production process.
[0061] The extruded fluorosilicone oil-resistant pipeline hose is produced using an extruded fluorosilicone oil-resistant pipeline hose forming device, and includes a fluorosilicone layer 16; the inner rubber layer 17 is wrapped around the outside of the fluorosilicone layer 16; the fiber reinforced layer 18 is wound around the outside of the inner rubber layer 17; and the outer rubber layer 19 is wrapped around the outside of the fiber reinforced layer 18.
[0062] In this embodiment, a suitable fluorosilicone raw material is selected according to actual needs. The thickness of the fluorosilicone layer 16 is determined in consideration of the balance between cost and performance. It can not only meet the basic oil resistance and performance requirements, but also control the amount of fluorosilicone used to reduce costs. A rubber material with low cost and certain flexibility and adhesion is selected as the raw material for the internal rubber layer 17. This material has good compatibility with fluorosilicone, and can significantly reduce production costs while ensuring the overall performance of the hose. During the implementation process, a special mixing equipment is used to mix the raw materials for the internal rubber layer 17 to ensure its uniformity, and then it is transported to the molding device through precise metering equipment.
[0063] Choose high-strength fiber materials, such as glass fiber or aramid fiber. Before use, clean and pre-treat the fiber, such as dipping it in a glue solution that has good adhesion to the internal and external glue layers to improve the bonding between the fiber and the glue layer. The fiber diameter, strength and other performance indicators are determined according to the specific use requirements of the hose. Use oil-resistant and weather-resistant rubber materials as the raw materials for the external rubber layer 19. This rubber should have low permeability and good anti-aging properties to protect the internal structure of each layer. During the production process, the raw materials for the external rubber layer 19 should also be mixed and metered to ensure its stable quality.
[0064] The advantage is that by wrapping the inner rubber layer 17 outside the fluorosilicone layer 16, it is avoided to use all fluorosilicone as the inner rubber layer material, which greatly reduces the production cost. Under the premise of meeting the basic performance requirements of the hose, the use of the inner rubber layer 17 material with a lower cost can significantly save the raw material cost in large-scale production and improve production efficiency.
[0065] The inner rubber layer 17 wrapped around the outer side of the fluorosilicone layer 16 can effectively prevent the fluorosilicone layer 16 from deforming when the fiber reinforcement layer 18 is wound. The inner rubber layer 17 provides the necessary support for the fluorosilicone layer 16, ensuring the shape stability of the hose during the production process, thereby ensuring the overall performance and quality of the hose. Without the inner rubber layer 17, the thinner fluorosilicone layer 16 is prone to local deformation when it is wound around the fiber reinforcement layer 18 due to the tension and pressure of the fibers, which affects the structural integrity and performance of the hose.
[0066] This hose structure has good comprehensive performance while ensuring cost-effectiveness. The fluorosilicone layer 16 provides basic oil resistance, the internal rubber layer 17 reduces costs while enhancing the flexibility and adhesion of the hose, the fiber reinforcement layer 18 improves the structural strength of the hose, and the external rubber layer 19 provides oil resistance and weather resistance. The various layers work together to make the hose suitable for oil transportation in a variety of industrial environments, such as oil pipeline systems in the automotive manufacturing, chemical and other industries, with wide applicability and good reliability.
