Description

Technical Field

[0001] The present application relates to the technical field of immersion devices, and more specifically, to a contactless immersion device and a composite foil production system. Background Art

[0002] In order to improve the surface properties of materials or pre-treat materials, the processing of rolled materials is often accompanied by the process of unwinding and immersing them in chemical liquids; for example, the process of producing composite foils involves the treatment of passivation liquid. In this type of production process, in order to facilitate compounding or other processing processes, upstream and downstream coordinated transmission is usually required to maintain the stretched state of the material. Based on this, in order to facilitate the film roll to enter the tank body placed in the liquid for immersion, rollers are usually set at the bottom of the tank body to make the film roll turn to enter the tank, and continue to be transmitted downstream after passing the rollers. In this process, the material will inevitably come into contact with the roller surface during the immersion process, and the material itself may be stretched, deformed, or damaged due to factors such as friction and stretching. At the same time, the underwater rollers often need to be sealed, which has problems such as complex structure, high cost, and difficulty in ensuring stability.

[0003] Therefore, the prior art urgently needs a contactless immersion device to realize immersion processing during the transmission process, improve the existing immersion material feeding structure, and avoid the adverse effects caused by roller surface contact during the immersion process. Utility Model Content

[0004] The present application aims to overcome at least one of the shortcomings of the above-mentioned prior art, provide a contactless immersion device, improve the immersion material feeding structure, and solve the adverse effects caused by contact with the roller during the transmission immersion process of the prior art, thereby improving the immersion effect and the corresponding product quality.

[0005] The technical solution adopted in this application is a contactless immersion device, comprising:

[0006] A first immersion tank having an open tank body for accommodating liquid;

[0007] The steering tube is arranged in the first immersion tank. The material entering the first immersion tank passes around the steering tube and then leaves the first immersion tank. The steering tube is provided with a plurality of liquid outlets. The plurality of liquid outlets cooperate with the liquid outlets to allow the material to float on the outside of the steering tube and pass through the steering tube.

[0008] The liquid inlet pipe is connected with the liquid outlet.

[0009] In the present application, the liquid inlet pipe supplies liquid to the liquid outlet, and the liquid outlet sprays liquid outward to form a thrust area. After the material enters the first immersion tank, the multiple liquid outlets of the steering tube body cooperate to make the material float on the outside of the steering tube body. At this time, the material presents a material conveying process without contact with the steering tube body. At the same time, the material can fully contact the liquid whether it is close to the steering tube body or far away from the steering tube body, so as to achieve full processing of the material. Based on the contactless immersion device described in the present application, contactless steering can be achieved. When the material is a membrane material, the strain on the material and the friction damage to the surface of the material are reduced. It is beneficial to protect the material itself and avoid stretching deformation, strain, etc. In addition to ensuring the immersion effect and material quality of the material, the corresponding immersion feeding device is simpler and more convenient to repair and replace, and eliminates structures such as transmission bearings, bearing seats, and guide rollers, with a simple structure and low cost.

[0010] Specifically, the liquid inlet pipe provides liquid to the liquid outlet, and the liquid sprayed outward from the liquid outlet forms an outward thrust based on the water pressure; when the material passes through the steering tube body, if the material turns at the bottom of the steering tube body, the material will tend to move upward due to the stretching of the upstream and downstream winding and unwinding, and the liquid outlet on the bottom of the steering tube body provides a downward thrust, so the material will stay under the steering tube body, float on the bottom of the steering tube body and continue to pass through the steering tube body. Similarly, when the material turns at the top of the steering tube body, the same process occurs, the liquid outlet is set on the top of the steering tube body, the material floats on the top of the tube body and continues to pass through the steering tube body. The gap between the material and the steering tube body can be adjusted by adjusting the water pressure of the liquid inlet pipe or by coordinating the water pressure with the upstream and downstream tensile tension of the material.

[0011] Furthermore, the steering tube body is provided with a cavity, through which a liquid inlet pipe communicates with the corresponding liquid outlet on the steering tube body. The steering tube body can be directly connected to the liquid inlet pipe, forming a convenient liquid outlet passage. Liquid in the liquid inlet channel directly enters the cavity and is discharged outward through the liquid outlet. Depending on the internal cavity requirements, the appropriate steering tube material can also be selected.

[0012] Furthermore, the liquid includes a passivation liquid and other liquids. For example, the common post-processing process of the composite current collector in the prior art involves the aforementioned roller immersion process, including the passivation process. However, the present application is applied to the passivation liquid treatment, which not only facilitates the improvement of the passivation effect, but more importantly, it can avoid friction and surface loss of ultra-thin materials, thereby ensuring improved product quality.

[0013] Furthermore, the liquid outlet holes on the steering tube body are arranged at least in an array; in addition, they can also be further arranged in a rectangular arrangement, a mesh arrangement or a combined arrangement, etc., so as to evenly discharge the liquid outward to form a suitable thrust; the liquid is evenly delivered in the longitudinal and transverse directions to achieve a corresponding appropriate floating thrust effect according to the actual effect.

[0014] Furthermore, the diameter of the liquid outlet hole is in the range of 0.8 to 2.2 mm; and / or, liquid outlet holes are provided in the length direction and circumferential direction of the steering tube body. And / or, a groove-shaped liquid outlet groove is provided on the steering tube body, and the liquid outlet hole is provided on the bottom surface of the liquid outlet groove, and the liquid outlet hole is communicated with the liquid outlet groove; the liquid discharged from the liquid outlet hole is discharged outward through the liquid outlet groove. Setting this diameter facilitates the control of the liquid outlet hydraulic range, and cooperates with the liquid outlet holes with a certain density distribution to achieve a more uniform outward thrust; and the liquid outlet hole is provided in the liquid outlet groove, so that it is convenient to form a diffusion pushing area outward through the liquid outlet groove, and only a small number of liquid outlet grooves are provided in the circumference to float and push the corresponding passing materials, and it is convenient to avoid turbulence between adjacent liquid outlet holes in the circumference. The liquid outlet groove can be a liquid outlet groove with a length direction consistent with the length direction of the steering tube body.

[0015] Furthermore, the invention comprises a plurality of steering tubes, and the material passes through the plurality of steering tubes in an S-shaped path. Furthermore, the invention comprises three or more staggered steering tubes, and the material passes through all the steering tubes in an S-shaped path.

[0016] Furthermore, multiple liquid outlet grooves are uniformly arranged around at least the material-passing side of the steering tube. That is, around the circumference of the steering tube, liquid outlet grooves are provided at least on the material-passing side (the area where the material generates a counteracting force against the steering tube when passing through), facilitating the provision of thrust against the passing material through the liquid outlet holes and the liquid outlet grooves. This uniform arrangement facilitates uniform application of force to all locations on the material, allowing the material to float evenly outside the steering tube, thereby avoiding deviations caused by uneven thrust. Furthermore, the liquid discharge from the multiple liquid outlet grooves collectively forms a liquid outlet action area. Furthermore, the liquid outlet action area directly faces the material passing through the steering tube, and the multiple liquid outlet grooves are uniformly and symmetrically distributed around the center of the liquid outlet action area. For example, in the case where material passes below the steering tube and the material positions on the entry and exit sides are symmetrical, multiple liquid outlet grooves are provided at least on the lower side of the steering tube, and the multiple liquid outlet grooves are uniformly and symmetrically distributed around the circumference of the steering tube, with the lower end of the steering tube as the center of symmetry.

[0017] Furthermore, the cross-sectional shape of the liquid outlet groove is an inverted trapezoid. Furthermore, the vertex angle of the inverted trapezoid ranges from 90 to 150 degrees. The liquid outlet groove can divert the liquid out of the liquid outlet hole outward in an outwardly diffusing manner, thereby forming an outwardly diffusing thrust area. Furthermore, the depth of the liquid outlet groove is 1 to 20 mm; when the steering tube body is formed of a thin-walled PPH tube or the like, the depth of the liquid outlet groove can be 1 to 2 mm. Furthermore, when the length of the liquid outlet groove in the length direction of the steering tube body is relatively short, multiple liquid outlet grooves can be provided in the length direction of the steering tube body.

[0018] Furthermore, the circumferential width of the liquid discharge action area accounts for more than 1 / 5 of the circumferential length of the steering tube body; further, the circumferential width of the liquid discharge action area accounts for more than 2 / 9 of the circumferential length of the steering tube body; further, the circumferential width of the liquid discharge action area accounts for 2 / 9 to 2 / 3 of the circumferential length of the steering tube body. In order to ensure the uniform distribution of the position of the liquid discharge action material, a certain degree of circumferential coverage is required; at the same time, to avoid the liquid discharge holes at the edge of the liquid discharge action area from disturbing each other and preventing uniform action, it is necessary to ensure that the width of the corresponding liquid discharge action area is greater than the width of the actual material counteracting force area, so that the liquid discharge holes corresponding to the edge of the actual material action area are not the liquid discharge holes at the edge of the liquid discharge action area.

[0019] Furthermore, the width of the liquid outlet groove is 1 to 2.5 mm; and / or, in the length direction of the steering tube body, the spacing between adjacent liquid outlet holes is 5 to 15 mm, specifically, when the liquid outlet hole is located in the liquid outlet groove, the spacing between adjacent liquid outlet holes in the same liquid outlet groove is 5 to 15 mm; further, three liquid outlet grooves are symmetrically and evenly arranged in the lateral circumferential direction of the material passing through the steering tube body; the central angle formed between the two outermost liquid outlet grooves is 100 to 120°; or, two liquid outlet grooves are symmetrically and evenly arranged in the lateral circumferential direction of the material passing through the steering tube body; the central angle formed between the two liquid outlet grooves is 80 to 100°.

[0020] Furthermore, a first introduction roller and a first deflection roller are fixed on both sides of the first immersion tank respectively. The material enters the first immersion tank through the first introduction roller and is guided downstream through the first deflection roller after leaving the first immersion tank.

[0021] Furthermore, it also includes a second immersion tank, wherein the first immersion tank is arranged in the second immersion tank; the side wall of the second immersion tank is provided with a liquid inlet pipe installation hole; the second immersion tank is provided with a liquid discharge port; the liquid inlet pipe and the liquid discharge port are connected by a circulation pump. Furthermore, when the liquid discharge from the liquid discharge port continuously fills the first immersion tank, the excess liquid overflows from the upper end of the first immersion tank and enters the second immersion tank. The liquid discharge port of the second immersion tank is discharged outward under the action of the circulation pump and finally circulates to the liquid inlet pipe. That is, the present application can use the second immersion tank as a storage space for liquid transition and facilitate the installation of other components such as the liquid inlet pipe.

[0022] Furthermore, a second introduction roller and a second deflection roller are fixed on both sides of the second immersion tank respectively; the material moves toward the first immersion tank in the second immersion tank through the second introduction roller, and is guided downstream through the second deflection roller after leaving the second immersion tank.

[0023] Furthermore, the second inlet roller is higher than the first inlet roller, and the second outlet roller is higher than the first outlet roller. Furthermore, the material enters the first immersion tank via the second inlet roller and the first inlet roller, then exits the first immersion tank through the diverting pipe within the first immersion tank and is directed downstream via the first outlet roller and the second outlet roller.

[0024] Furthermore, the material passes through the same side surface against the first introduction roller and the first deflection roller. Furthermore, the material passes through the same side surface against the first introduction roller, the second introduction roller, the first deflection roller, and the second deflection roller. This allows all introduction and deflection actions to be applied only to one side of the material, avoiding contact with the other side and the resulting quality impact. If there is an unlaminated side and a laminated side, each action can be applied only to the laminated side, while the steering tube body allows for contactless material feeding, essentially completely avoiding any adverse effects on the material during feeding.

[0025] Furthermore, the first immersion tank is provided with a liquid discharge port, and the liquid inlet pipe and the liquid discharge port are connected via a circulation pump. That is, in addition to the aforementioned method of forming a circulation channel through the second immersion tank, a circulation channel can also be realized by providing a liquid discharge port through the first immersion tank.

[0026] Furthermore, the steering tube body is formed of a PPH tube; and / or, a regulating valve for adjusting water pressure is provided on the liquid inlet pipe; and / or, a filter column is provided on the liquid inlet pipe. Based on the hydraulic propulsion principle of the present application, the PPH tube can be used to realize the material feeding and steering in the immersion tank, and based on the floating propulsion method of the steering tube body of the present application, no seals, bearing seats and complex roller structures are required; the steering tube body can be conveniently made of anti-corrosion materials, and can effectively achieve anti-corrosion effects even when immersed in liquid for a long time, effectively reducing equipment costs and maintenance difficulties. More importantly, the steering tube body of the present application does not require complex assembly structures such as sealed bearings. A single steering tube body occupies a small space, so multiple steering tube bodies can be arranged in a smaller space, thereby facilitating the material to pass through multiple steering tube bodies, increasing the residence time in the immersion area, and fully improving the immersion effect. The regulating valve can be used to adjust the water pressure and further adjust the corresponding hydraulic floating degree. The filter column facilitates filtering impurities that may be generated during the processing, thereby avoiding conditions such as blockage of the liquid outlet.

[0027] Another object of the present application is to provide a composite foil production system, comprising the aforementioned contactless immersion device. Furthermore, the composite foil comprises a composite current collector.

[0028] Compared with the prior art, the beneficial effects of the present application are: it can realize contactless transmission immersion and steering, and when the material is a membrane material, it can reduce the strain on the material and the friction on the material surface. It is beneficial to protect the material itself and avoid stretching, deformation and strain. It is also convenient to achieve the maximum stay time in the limited immersion tank space, significantly improving the immersion effect. Moreover, in addition to improving the guarantee of material immersion effect and material quality, the corresponding immersion feeding device is simpler and more convenient to repair and replace, and the transmission bearings, bearing seats, guide rollers and other structures are eliminated. It has a simple structure, reduced costs, is easy to prevent corrosion, and has a long service life. That is, based on the contactless immersion device described in this application, the quality of the corresponding processed products can be significantly improved, and the adverse effects of the feeding and immersion process can be reduced; and compared with traditional equipment, the complexity is reduced, and it is convenient for maintenance and replacement.

[0041] Example 1

[0042] like Figures 1 to 5 As shown, this embodiment discloses a contactless immersion device 1000, comprising:

[0043] The first immersion tank 1100 has an open tank body for accommodating liquid;

[0044] The steering tube 1300 is disposed in the first immersion tank 1100. The material 1500 entering the first immersion tank 1100 passes around the steering tube 1300 and then exits the first immersion tank 1100. The steering tube 1300 is provided with a plurality of liquid outlets 1310. The plurality of liquid outlets 1310 cooperate with liquid discharge to allow the material 1500 to float outside the steering tube 1300 and pass through the steering tube 1300. In this embodiment, the plurality of steering tubes 1300 are arranged in a staggered manner, so that the material 1500 forms an S-shaped path through all of the steering tubes 1300.

[0045] The liquid inlet pipe 1400 is connected to the liquid outlet hole 1310 . In this embodiment, a cavity is provided in the steering tube body 1300 , and the liquid inlet pipe 1400 is connected to the liquid outlet hole 1310 through the cavity of the steering tube body 1300 .

[0046] In this embodiment, the steering tube body 1300 is formed of a PPH tube; the liquid inlet pipe 1400 is provided with a regulating valve (not shown in the figure) for adjusting the water pressure; and the liquid inlet pipe 1400 is provided with a filter column (not shown in the figure).

[0047] like Figure 8 、 9As shown, in this application, the liquid inlet pipe 1400 supplies liquid to the liquid outlet hole 1310, and the liquid outlet hole 1310 sprays liquid outward to form a thrust area. When the material 1500 enters the first immersion tank 1100, the multiple liquid outlet holes 1310 of the transmission roller body cooperate to make the material 1500 float outside the steering tube body 1300. At this time, the material 1500 is transported without contact with the steering tube body 1300. At the same time, the material 1500 can fully contact the liquid whether it is close to the steering tube body 1300 or far away from the steering tube body 1300, so that the material 1500 can be fully processed. Specifically, the liquid inlet pipe 1400 supplies liquid to the liquid outlet 1310. The liquid sprayed outward from the liquid outlet 1310 creates an outward thrust based on the water pressure. When the material 1500 passes through the steering tube 1300, if the material 1500 is diverted by the lower side of the steering tube 1300, the material 1500 will tend to move upward due to the upstream and downstream winding and unwinding. At this time, the liquid outlet 1310 on the lower side of the steering tube 1300 provides a downward thrust. At this time, the material 1500 will remain below the steering tube 1300, floating on the lower side of the steering tube 1300 and continuing to pass through the steering tube 1300. The gap between the material 1500 and the steering tube 1300 can be adjusted by adjusting the water pressure in the liquid inlet pipe 1400 and / or the upstream and downstream tensile tension of the material 1500. The liquid includes a passivation liquid and other liquids. For example, the present application can be applied to passivation liquid treatment.

[0048] In this embodiment, a cavity is provided in the steering tube body 1300, and the liquid inlet pipe 1400 is connected to the liquid outlet hole 1310 through the cavity. The steering tube body 1300 can be directly connected to the liquid inlet pipe 1400, and the liquid in the liquid inlet channel directly enters the cavity and is discharged outward from the liquid outlet hole 1310. According to the requirements of the internal cavity, a corresponding pipe material for the steering tube body 1300 can also be selected. On the steering tube body 1300, the liquid outlet holes 1310 are at least arranged in an array; in addition, they can also be further arranged in a rectangular arrangement, a mesh arrangement, or a combination arrangement, etc., so as to evenly discharge the liquid outward to form a suitable thrust; according to the actual effect, a corresponding suitable floating thrust effect is achieved; in this embodiment, they can be arranged in a regular array of rectangles.

[0049] like Figure 6 、 7As shown, in addition to directly utilizing the liquid outlet holes 1310 to form a propulsion structure on the surface, in this embodiment, to enhance the stability and controllability of the floating propulsion, a groove-shaped liquid outlet groove 1320 is provided on the steering tube body 1300. The liquid outlet holes 1310 are located on the bottom surface of the liquid outlet groove 1320, with both ends of the liquid outlet hole 1310 communicating with the liquid outlet groove 1320 and the cavity. The diameter of the liquid outlet holes 1310 ranges from 0.8 to 2.2 mm. The coordination of the liquid outlet holes 1310 and the liquid outlet groove 1320 allows the liquid to diffuse outwards and form a propulsion area. Only a small number of liquid outlet grooves 1320 are required around the circumference to float the corresponding material 1500 and avoid turbulence between adjacent liquid outlet holes 1310. The depth of the liquid outlet groove 1320 ranges from 1 to 20 mm. When the steering tube body 1300 is formed of a thin-walled PPH tube, for example, the depth of the liquid outlet groove 1320 can be 1 to 2 mm. In addition to providing a single through-groove directly along the length of the steering tube 1300, when the length of the liquid outlet groove 1320 along the length of the steering tube 1300 is relatively short, multiple liquid outlet grooves 1320 can be provided along the length of the steering tube 1300 to cover the entire length of the steering tube 1300, as required (not shown). Furthermore, in addition to providing a conventional rectangular cross-sectional groove shape, the liquid outlet groove 1320 can also be provided with an inverted trapezoidal cross-sectional shape to increase the effective range of the liquid outlet groove 1320. The inverted trapezoidal cross-sectional shape has a vertex angle range of 90 to 150 degrees, i.e., a trumpet-like cross-sectional shape that expands outward.

[0050] like Figure 7 、 8 As shown, multiple liquid outlet grooves 1320 are evenly arranged around the circumference of at least the side of the steering tube 1300 where the material 1500 passes. This ensures that the liquid outlet grooves 1320 are located at least on the side where the material 1500 passes (the area where the material 1500 generates a counteracting force against the steering tube 1300 as it passes). The liquid outlet holes 1310 and the liquid outlet grooves 1320 provide a thrust against the passing material 1500. The multiple liquid outlet grooves 1320 collectively form a liquid outlet action area 1330 (this area at least forms a barrier similar to a liquid film to resist the passing material 1500). The liquid outlet action area 1330 directly faces the material 1500 passing through the steering tube 1300, and the multiple liquid outlet grooves 1320 are evenly and symmetrically distributed around the center of the liquid outlet action area 1330.

[0051] In this embodiment, in order to ensure a certain degree of coverage in the circumferential direction, and the length of the liquid discharge action area 1330 in the circumferential direction is greater than the length of the actual material 1500 offsetting force area (to avoid situations such as unstable edge thrust of the liquid discharge action area 1330 when the circumferential length is the same), the circumferential length of the liquid discharge action area 1330 can be configured to account for more than 1 / 5 of the circumferential length of the steering tube body 1300; more specifically, the circumferential width of the liquid discharge action area 1330 accounts for more than 2 / 9 of the circumferential length of the steering tube body 1300; or the circumferential length of the liquid discharge action area 1330 is controlled to account for 2 / 9 to 2 / 3 of the circumferential length of the steering tube body 1300.

[0052] In this embodiment, the width of the liquid outlet groove 1320 is 1 to 2.5 mm; in the longitudinal direction of the steering tube body 1300, the spacing between adjacent liquid outlet holes 1310 is 5 to 15 mm; on this basis, two or three liquid outlet grooves can be provided in the circumferential direction of this embodiment, for example, three liquid outlet grooves 1320 are symmetrically and evenly provided in the lateral circumferential direction of the material 1500 of the steering tube body 1300, and the central angle α formed between the two outer liquid outlet grooves 1320 is 100 to 120°, such as Figure 7 、 8 As shown; another example, the material 1500 of the steering tube 1300 is symmetrically and evenly provided with two liquid outlet grooves 1320 in the lateral circumferential direction; the central angle α formed between the two liquid outlet grooves 1320 is 80 to 100 degrees, as shown Figure 9 shown.

[0053] like Figures 2 to 5As shown, a first introduction roller 1110 and a first deflection roller 1120 are fixed on both sides of the first immersion tank 1100. The material 1500 enters the first immersion tank 1100 via the first introduction roller 1110 and is guided downstream via the first deflection roller 1120 after exiting the first immersion tank 1100. In this embodiment, a second immersion tank 1200 is also included. The first immersion tank 1100 is arranged within the second immersion tank 1200. A mounting hole for a liquid inlet pipe 1400 is provided on the sidewall of the second immersion tank 1200. The second immersion tank 1200 is provided with a liquid discharge port (not shown in the figure). The liquid inlet pipe 1400 and the liquid discharge port are connected by a circulation pump. When liquid discharge from outlet 1310 continuously fills first immersion tank 1100, excess liquid overflows from the upper end of first immersion tank 1100 and enters second immersion tank 1200. Liquid is discharged from the outlet of second immersion tank 1200 by a circulating pump and eventually circulates to liquid inlet pipe 1400. Second immersion tank 1200 is secured to two sides with second introduction rollers 1210 and second deflection rollers 1220. The second introduction rollers 1210 are higher than the first introduction rollers 1110, while the second deflection rollers 1220 are higher than the first deflection rollers 1120. Material 1500 enters first immersion tank 1100 via second introduction rollers 1210 and first introduction rollers 1110, then exits first immersion tank 1100 through a diverting pipe within first immersion tank 1100 and is directed downstream via first deflection rollers 1120 and second deflection rollers 1220. In the above-mentioned passing process, the material 1500 may pass through the first introduction roller 1110 , the second introduction roller 1210 , the first deflection roller 1120 , and the second deflection roller 1220 on the same side.

[0054] In addition to the overflow of the aforementioned first immersion tank 1100 into the second immersion tank 1200 and the drainage method through the second immersion tank 1200, drainage can also be achieved based on a separate first immersion tank 1100, that is, a drainage port is directly provided in the first immersion tank 1100, and the liquid inlet pipe 1400 and the drainage port are connected through a circulation pump.
