Description

Technical Field

[0001] This invention relates to the field of extrusion molding technology for lined hoses, and particularly to ultraviolet light curing extrusion molding equipment for lined hoses and thickness adjustment components. Background Technology

[0002] The laminated structure of the inner lining hose consists of an inner membrane, a fiber fabric layer, a geomembrane, and an outer membrane, from the inside out. The fiber fabric layer is a continuous reinforced glass fiber composite felt that is overlapped and wound around the surface of the inner membrane, and vacuum injection is performed at the beginning of the winding process.

[0003] The UV-curable inner lining hose thickness adjustment extrusion molding equipment with application number CN202311694566.4 includes a bidirectional drive mechanism, a frame, a height adjustment mechanism, a height half-adjustment mechanism, an inner lining hose, two pressure bars, and two conveyor belts. It can perform transverse rolling on the flat inner lining hose, so that the adhesive in the inner lining hose can be distributed more evenly, avoiding the weakening or even failure of the repair ability of the UV-curable inner lining hose. It can also roll on both the top and bottom sides of the flat inner lining hose.

[0004] However, in actual use, when the inner lining hose is filled with adhesive, there will be gaps in the adhesive during the filling process. Repeated squeezing with pressure rollers only compacts the areas with more adhesive, but it is difficult to ensure that the adhesive fills the gaps. Moreover, simple roller squeezing cannot smooth the adhesive; repeated rolling with pressure rollers is required. During this process, gaps are created between areas with more and less adhesive, resulting in uneven distribution of adhesive in the inner layer of the hose. This exacerbates the unevenness of the adhesive during squeezing, and even after the inner lining hose is rolled with pressure rollers, its flatness is still poor.

[0005] Therefore, the present invention proposes an ultraviolet light curing inner lining hose extrusion molding equipment and a thickness adjustment component to solve the above problems. Summary of the Invention

A first pressure solenoid valve is installed on each set of first branch pipes. A second branch pipe corresponding to and communicating with multiple sets of second annular air storage tanks is also connected to the air supply pipe, and a second pressure solenoid valve is installed on each set of second branch pipes.

[0009] Preferably, the cross-section of the rolling wheel is elliptical. After the first annular gas storage tank is filled with gas, the first expansion ring expands outward to form a compression ring, and the pressure threshold of the first pressure solenoid valve is the same.

[0010] Preferably, after the second annular gas storage tank is filled with gas, the second expansion ring expands outward to form an arc-shaped pressure ring, and the pressure threshold of the second pressure solenoid valve is the same.

[0011] Preferably, the conveyor includes a fixed frame, a conveyor roller is mounted on the fixed frame, a conveyor belt is mounted on the conveyor roller, the hose body is placed on the conveyor belt, supports are provided on the left and right sides of the conveyor belt, and a conveyor seat that fits against the bottom of the conveyor belt is fixedly installed between the left and right supports.

[0012] Preferably, the first drive component, the second drive component, and the third drive component have the same structure and are each configured as two groups, symmetrically distributed on the left and right sides of the conveyor belt, and are all fixed to the top of the support.

[0013] Preferably, a slide rail is provided on the opposite side wall of the two sets of first drive components, an electromagnet plate is fixed at the bottom of the slide rail, a magnetic slide is slidably mounted on the top of the slide rail, and a support spring is fixedly connected between the electromagnet plate and the magnetic slide.

Detailed Implementation

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0021] like Figures 1 to 8As shown, this embodiment discloses a UV-curable inner liner hose extrusion molding equipment, including a conveyor 10, on which a hose body 20 is conveyed. First drive components 30 are mounted on the front ends of the left and right sides of the conveyor 10. A compaction component 40 for guiding the hose body 20 is mounted between two sets of first drive components 30. A second drive component 50 is disposed behind each set of first drive components 30. A flattening component 60 for scraping the hose body 20 is mounted between two sets of second drive components 50. Third drive components 70 are mounted on the rear ends of the left and right sides of the conveyor 10. A compaction seat 80 for tamping and compacting the hose body 20 is mounted between two sets of third drive components 70. The hose body 20 is placed on the conveyor 10 for conveying. During this process, according to the hose... The thickness control of the body 20 is achieved by the first drive assembly 30 driving the rolling assembly 40 to adjust its height, so that the bottom of the rolling assembly 40 is in contact with the surface of the hose body 20. This allows the rolling assembly 40 to roll the bulges on the hose body 20 during transport, achieving the purpose of segmentation, material equalization, and flattening. This facilitates the segmentation and even distribution of the bulges, resulting in a more uniform distribution of the adhesive. Simultaneously, the second drive assembly 50 controls the flattening assembly 60 to adjust synchronously, pressing and flattening the segmented and evenly distributed bulges to achieve the purpose of spreading and rolling. Subsequently, the compaction seat 80 moves up and down reciprocally under the action of the third drive assembly 70, which enables the compaction seat 80 to regularly compact the surface of the hose body 20, completing the pressure and flattening of the hose body 20.

[0022] Please see Figures 4-7 The rolling assembly 40 includes a rolling roller 43, on which rolling wheels 44 are evenly arranged along the length direction. A material distribution groove 45 is set between two adjacent sets of rolling wheels 44. A first expansion ring 46 is set on the outer edge of each set of rolling wheels 44, and a second expansion ring 47 is set at the material distribution groove 45. A first annular air storage groove 48 corresponding to the first expansion ring 46 is opened in each set of rolling wheels 44, and a second annular air storage groove 49 corresponding to the second expansion ring 47 is opened in the rolling roller 43. By setting multiple sets of rolling wheels 44 on the rolling roller 43, uniform pressing of the hose body 20 is achieved, ensuring uniform distribution of the adhesive inside the hose body 20. The evenly arranged rolling wheels 44 and the material distribution grooves 45 between them can evenly distribute the adhesive.

[0023] It is worth noting that the rolling assembly 40 also includes a central shaft 41, and the rolling roller 43 is fixedly sleeved on the outer wall of the central shaft 41. Both ends of the central shaft 41 are fixed with rotating shafts 42, and an air supply pipe is embedded in the center of the central shaft 41. The air supply pipe is connected to an external air source, and a first branch pipe is connected to the air supply pipe and communicates with multiple sets of first annular air storage tanks 48. Each set of first branch pipes is equipped with a first pressure solenoid valve. The air supply pipe is also connected to a second branch pipe and communicates with multiple sets of second annular air storage tanks 49. Each set of second branch pipes is equipped with a second pressure solenoid valve.

[0024] Please see Figures 4-7 The roller 44 has an elliptical cross-section and is evenly arranged along the axis of the roller 43. It can perform segmented rolling on the bulges on the hose body 20 to achieve the purpose of dividing the bulges. At the same time, when dividing the bulges into different small bulges, the second expansion ring 47 at the material leveling groove 45 can roll the divided small bulges to achieve the purpose of flattening. The cooperation between the roller 44 and the material leveling groove 45 plays the role of dividing, flattening and spreading the bulges.

[0025] Please see Figures 4-7 After gas is filled into the first annular gas storage tank 48, the first expansion ring 46 expands outward to form a compression ring, and the pressure threshold of the first pressure solenoid valve is the same. After gas is filled into the second annular gas storage tank 49, the second expansion ring 47 expands outward to form an arc-shaped pressing ring, and the pressure threshold of the second pressure solenoid valve is the same. In actual use, the first expansion ring 46 and the second expansion ring 47 set on the outer edge of each set of rolling wheels 44 can control the expansion degree of the expansion ring by controlling the amount of gas input into the annular gas storage tank. Then, according to the shape of the bulge, the expansion amount of the first expansion ring 46 and the second expansion ring 47 on the rolling wheel 44 is controlled in real time to achieve a precise extrusion and division effect. In this way, the uniform distribution of the adhesive in the hose body 20 can be guaranteed, avoiding the phenomenon of excessively high or low local concentration, and effectively improving the uniformity of the adhesive in the molding process.

[0026] It should be noted that irregular bulges or depressions exist on the surface of the hose body 20. These bulges may be caused by uneven resin distribution, differences in raw materials, etc. The bulges are usually irregularly distributed along the length of the hose body 20, and are more concentrated in some areas, resulting in excessive adhesive in those areas and thinner adhesive in other areas. In this embodiment, the first expansion ring 46 and the second expansion ring 47 are expanded by gas filling to achieve precise segmentation, uniform flattening, and uniform distribution of adhesive on the bulges on the hose body 20. According to the shape changes of the bulges on the hose body 20, the shape adjustment of the first expansion ring 46 and the second expansion ring 47 can be specifically adjusted according to the different bulge parts, thereby ensuring efficient segmentation, uniform compression, rolling, and flattening of the hose.

[0027] The first expansion ring 46 is located on the outer edge of each set of rolling rollers 44. During operation, when gas is filled into the first annular gas storage tank 48, the first expansion ring 46 expands and bulges outward, forming a sharper conical outer edge, which has a stronger ability to divide bulges. When there are obvious bulges on the hose body 20, the first expansion ring 46 can expand in time and bulge outward to strengthen the division effect on the bulge. Especially in the position where the bulges are more concentrated, the first expansion ring 46 increases the expansion force to form a sharper conical pressing edge, which can generate a stronger dividing force in the bulge, thereby strengthening the squeezing and dividing effect on the bulge and squeezing the originally concentrated adhesive evenly. At this time, the first expansion ring 46, through precise division, makes the resin on the bulge part of the hose body 20 redistribute and evenly flatten it, avoiding the resin from being excessively concentrated in the bulge part and affecting the uniformity of the adhesive.

[0028] The second expansion ring 47 is located at the equalization groove 45 and works together with the first expansion ring 46 to ensure the pressing effect of the hose body. The shape adjustment of the second expansion ring 47 is mainly used to ensure the uniform distribution of the adhesive after pressing. When gas is filled into the second annular gas storage groove 49, the second expansion ring 47 expands and bulges outward, the depth of the equalization groove 45 decreases, and the squeezing effect of the adhesive evenly distributed in the equalization groove 45 is better. The main function of the second expansion ring 47 is to evenly flatten the small protrusions after division, ensuring that the adhesive is evenly distributed in the equalization groove 45. Especially after the raised part is pressed, the second expansion ring 47 can perform a final flattening on the surface of the hose body 20 to eliminate uneven adhesive distribution.

[0029] When the changes in bulges are more obvious, especially when the bulges on the surface of the hose are small or evenly distributed, the expansion force of the second expansion ring 47 is increased, which reduces the distance between the second expansion ring 47 and the surface of the hose body 20. This allows for uniform compression of the segmented small bulges, reduces the depth of the material distribution groove 45, enhances the flattening effect of the small bulges, ensures that the adhesive can be evenly distributed and reduces local over- or under-distribution, and strengthens the compression effect.

[0030] It is worth noting that the front end of the transmitter 10 is equipped with a vision sensor, which can detect the bulge shape on the hose body 20 in real time. This facilitates real-time control of the crushing component 40, allowing for a more suitable crushing scheme for the hose body 20 based on different bulge shapes. Specifically: When the bulges are concentrated and large, the first expansion ring 46 increases the expansion force, making it form a sharper conical outer edge, enhancing the segmentation effect, and pressing the adhesive out from the bulges to prevent local resin from being too concentrated. At this time, the second expansion ring 47 reduces its expansion degree and increases the depth of the uniform material tank, which can increase the space for the uniform material tank 45 to squeeze the segmented bulges, which is conducive to the guidance and flow of the adhesive in the bulges and avoids the situation of poor adhesive flow under short-term squeezing.

[0031] When the bulges are small and relatively dispersed, the first expansion ring 46 does not expand. The elliptical shape of the rolling roller 44 itself divides the bulges to avoid excessive division that could lead to an imbalance of the adhesive. Meanwhile, the second expansion ring 47 expands, reducing the space inside the equalization trough 45, enhancing the pressure effect on the small bulges, ensuring that the adhesive can be evenly distributed and reducing local over- or under-distribution, thus strengthening the extrusion effect.

[0032] Please see Figures 1-4 The conveyor 10 includes a fixed frame, on which a conveyor roller is mounted, and on which a conveyor belt is mounted. The hose body 20 is placed on the conveyor belt. Supports 12 are provided on the left and right sides of the conveyor belt, and a conveyor seat 11 that fits against the bottom of the conveyor belt is fixedly installed between the left and right supports 12. Since the conveyor belt's conveying structure is existing technology, it will not be described in detail here. The conveyor seat 11 is provided to support the conveyor belt, so that the hose body 20 can be conveyed smoothly.

[0033] Please see Figures 4-7 The first drive assembly 30, the second drive assembly 50, and the third drive assembly 70 have the same structure and are all set in two groups, symmetrically distributed on the left and right sides of the conveyor belt, and are all fixed on the top of the support 12. A slide rail 31 is provided on the opposite side wall of the two groups of first drive assemblies 30. An electromagnet plate 32 is fixed at the bottom of the slide rail 31, and a magnetic slide block 33 is slidably mounted on the top of the slide rail 31. A support spring 34 is fixedly connected between the electromagnet plate 32 and the magnetic slide block 33. The rotating shaft 42 is rotatably mounted on the magnetic slide block 33.

[0034] In actual use, the vision sensor can also detect the distance between the rolling roller 43 and the surface of the hose body 20, which facilitates the control of the first drive component 30 to drive the rolling component 40 to adjust its height, so that the rolling component 40 can perform rolling operation on the hose body 20. When current is introduced into the electromagnet plate 32, a magnetic attraction force is generated on the magnetic slide 33, which can cause the magnetic slide 33 to overcome the supporting force of the supporting spring 34 and drive the rolling component 40 to start moving down, thereby reducing the distance between the rolling component 40 and the surface of the hose body 20, so that the rolling roller 43 on the rolling component 40 can directly perform the operations of dividing, uniformizing and pressurizing the hose body 20.

[0035] Please see Figures 4-7The flattening assembly 60 includes two sets of fixed plates 61, and a compaction roller 62 is rotatably mounted between the two sets of fixed plates 61 via a rotating shaft. A flattening roller 63 is rotatably mounted between the fixed plates 61 in front of the compaction roller 62. The bottom of the flattening roller 63 is slightly higher than the bottom of the compaction roller 62. The bottom of the compaction roller 62 is attached to the top of the hose body 20. The flattening assembly 60 is designed to uniformly flatten the surface of the hose body 20 after it has been extruded and formed by the rolling assembly 40, ensuring uniform compaction and flattening of the surface of the hose body 20.

[0036] Specifically, the design of the compaction roller 62 ensures that the hose body 20 is always kept within the required pressure range during the conveying process, thereby avoiding unevenness on the hose surface caused by uneven pressure, which would affect the photocuring effect. The flattening roller 63 is located in front of the compaction roller 62 as an auxiliary element for flattening. The bottom of the flattening roller 63 is set slightly higher than the bottom of the compaction roller 62, which makes it easier for the flattening roller 63 to flatten the hose surface evenly and eliminate any possible small depressions or uneven areas. On this basis, the compaction roller 62 ensures that the hose body 20 is subjected to uniform force during the extrusion molding process, avoiding the phenomenon of excessively high or low local glue concentration, thereby improving the quality of the product.

[0037] The compaction roller 62 and the flattening roller 63 work together to compact the hose body 20, making its surface flat and smooth. The flattening roller 63 ensures that there are no obvious uneven or uneven areas on the surface of the hose during the molding process. The compaction roller 62 is used to compact the surface of the hose with appropriate pressure. The working together of the two rollers effectively improves the molding effect and avoids the problem of glue distribution caused by uneven surface.

[0038] This embodiment discloses a thickness adjustment component applied to a UV-curable inner liner tube extrusion molding equipment, comprising: The first drive assembly 30 is used to drive the rolling assembly 40 for height adjustment, to adjust the distance from the bottom of the rolling roller 43 to the surface of the hose body 20, and to make real-time adjustments according to the height of the resin impregnation liquid protrusion.

[0039] The second drive assembly 50 is used to drive the flattening assembly 60 to adjust its height so that it matches the rolling assembly 40, which facilitates the flattening operation of the hose body 20 surface, ensures that the hose body 20 surface is flat, prevents the adhesive from concentrating in a certain part or spreading unevenly, thereby improving the surface quality of the formed hose.

[0040] The third drive assembly 70 is used to drive the compaction seat 80 for height adjustment and to drive the compaction seat 80 to perform regular compaction operations on the hose body 20. Although the third drive assembly 70 has the same structure as the first drive assembly 30 and the second drive assembly 50, the driving form of the third drive assembly 70 is completely different. The control system can change the attraction state of the electromagnet plate 32 to the magnetic slide 33 by controlling the current input to the electromagnet plate 32 in the third drive assembly 70, that is, by inputting current in stages. At this time, the electromagnet plate 32 generates a magnetic attraction force on the magnetic slide 33, which can cause the magnetic slide 33 to overcome the supporting force of the supporting spring 34 and drive the compaction seat 80 to move down quickly. Then, the compaction seat 80 is used to compact the surface of the flattened hose body 20. Subsequently, the electromagnet plate 32 is de-energized, and the compaction seat 80 is reset under the action of the rebound force of the supporting spring 34. Thus, the third drive assembly 70 drives the compaction seat 80 to achieve reciprocating up and down movement, completing the pressure compaction operation of the hose body 20.

[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
