TECHNICAL FIELD

[0001] The utility model belongs to the electrode foil production technical field, especially relates to a strip surface liquid flow removing device. BACKGROUND

[0002] In the three-dimensional foil production process, the base material is treated by the liquid tank, and then needs to be dried, and the liquid on the surface of the base material needs to be removed as much as possible after coming from the liquid tank to reduce the drying cost.

[0003] In the prior art, some liquid removing devices use a water scraping rod to scrape the liquid flow on the strip, which is difficult to completely scrape the residual liquid attached to the surface of the base material, and some liquid removing devices use a water absorbing roller to absorb the attached liquid flow, but the clamping degree of the water absorbing roller is difficult to adjust, which may cause the base material to wrinkle, the foil tension to be abnormal and the like. Therefore, there is a lack of a liquid removing device with good liquid removing effect and little effect on the normal strip running of the base material. UTILITY MODEL CONTENTS

[0008] In the above strip surface liquid flow removing device, the gas jet structure comprises a linear gas jet pipe, a plurality of gas holes obliquely facing the strip are uniformly distributed on the gas jet pipe in the axial direction, and the gas jet pipe is connected with a compressed gas generating assembly.

[0009] The jet pipe is parallel to the strip, and the compressed gas outputting assembly outputs compressed gas into the jet pipe, and the gas holes of the jet pipe output high-speed air flow, which are axially distributed and located on the same line, ensuring that the liquid flow blowing effect is applied to the entire width of the strip, ensuring the liquid removal effect. The compressed gas outputting assembly is well known and will not be described in detail.

[0010] In the above strip surface liquid flow removal device, one end of the jet pipe is closed, and the other end is connected to the compressed gas outputting assembly through the compressed pipeline.

[0011] The compressed gas outputting assembly inputs compressed gas from one end of the jet pipe, and due to the closure of the other end, the gas can only be output through the gas holes, achieving the effect of high-speed air flow output from the gas holes,

[0012] In the above strip surface liquid flow removal device, a partition is arranged in the jet pipe, which is located in the middle of the jet pipe and divides the inner cavity into two independent cavities, and the outer ends of the independent cavities are connected to the compressed gas outputting assembly through the compressed pipeline.

[0013] As an optimization scheme, the inner cavity of the jet pipe is divided into two parts by the partition, and each independent cavity is connected to the compressed gas outputting assembly, which is conducive to the similar high-speed air flow rate of each gas hole of the jet pipe, ensuring that the entire width of the strip can be subjected to good liquid blowing effect.

[0014] In the above strip surface liquid flow removal device, the jet pipe and the compressed gas outputting assembly are connected through the compressed pipeline, and an adjusting valve assembly for adjusting the output rate of high-speed air flow is arranged therebetween.

The inner wall of the sealing ring is provided with an internal thread, and the outer wall of the jet pipe is provided with an external thread extending from the end to the center. The internal thread and the external thread are engaged and connected.

[0019] The sealing structure can be achieved through a sealing ring, which is threaded onto the jet pipe. The position of the sealing ring on the jet pipe can be adjusted by rotating the sealing ring. When sealing is not required, the sealing ring can be kept at the outermost end. When sealing is required, the sealing ring can be screwed inward. The sealing ring is located on the radial outer side of the vent, achieving the effect of sealing the vent. The operation is convenient.

[0020] In the above-mentioned strip surface liquid removal device, the sealing structure includes sealing rings respectively disposed at both ends of the jet pipe. The sealing rings and the jet pipe are adapted to each other. The sealing rings are slidably sleeved on the jet pipe. A limiting bolt is provided on the side of the sealing ring away from the air hole. The limiting bolt is engaged with the connecting screw hole of the sealing ring, and its inner end abuts against the outer wall of the jet pipe. The inner wall of the sealing ring away from the connecting screw hole covers the outside of the air hole.

[0021] As a parallel solution for the closed-loop configuration, the closed-loop can also be simply fitted onto the jet pipe. It can move axially to adjust the number of vents to be sealed and is fixed in place by limiting bolts. It is flexible to install and remove; the limiting bolts are located on the side away from the vents. As it continues to be screwed in, the closed-loop is pulled towards the limiting bolts, ensuring a stable seal on the outside of the vents and providing a good sealing effect. Of course, due to the fitted connection, the shapes of the closed-loop and the jet pipe are more diverse. As long as they match, or even just as long as the closed-loop can fit onto the jet pipe and there is a sealing surface to close the vents, there are many options available.

[0022] In the above-mentioned strip surface liquid removal device, the conveyor rollers include a first conveyor roller and a second conveyor roller rotatably connected to the main frame. The first conveyor roller is located downstream of the strip drive and is positioned higher than the second conveyor roller.

[0023] The strip is wound around the first and second rollers, and there is a height difference between the first and second rollers, which makes the strip inclined. The downstream side of the strip drive is located at a high position, which helps the attached liquid to be blown away smoothly under the action of gravity and the high-speed airflow output obliquely downward by the jet structure.

[0024] In the strip surface liquid flow removing device, the overpassing roller further comprises a third overpassing roller rotatably connected to the main frame, the third overpassing roller is located at the upstream side of the second overpassing roller and is arranged higher than the second overpassing roller; the second overpassing roller is located in the liquid tank and is partially or completely submerged below the liquid level of the liquid tank; the strip is transmitted through the liquid of the liquid tank at the lowest position of the transmission.

Detailed Implementation

[0036] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0037] Example 1

[0038] Specific implementation examples Figures 1-3 As shown, the strip surface liquid removal device is set between two belt rollers 1. The strip 5 is wound around the two belt rollers 1. The device includes jet structures 2 set on both sides of the strip 5. The high-speed airflow output by the jet structures 2 is blown obliquely towards the strip 5, which can blow the liquid on the strip 5 off or blow it to the upstream side.

[0039] Specifically, this liquid fluid removal device removes liquid fluid by using a high-speed airflow output from the jet structure 2. This high-speed airflow acts obliquely on the strip 5 to ensure a good blowing effect.

[0040] like Figure 2 , 3 As shown, the jet structure 2 includes a straight jet pipe 21. Two jet pipes 21 are staggered on both sides of the strip. Several air holes 22 are evenly distributed axially on the jet pipe 21, which are obliquely opposite to the strip 5. One end of the jet pipe 21 is closed, and the other end is connected to the compressed gas generating assembly through a compression pipeline. A regulating valve assembly is connected in series on the compression pipeline.

[0041] Specifically, the jet pipe 21 is parallel to the strip 5. The compressed gas generating assembly outputs compressed gas into the jet pipe 21. The vents 22 of the jet pipe 21 output high-speed airflow. These vents 22 are axially distributed and located on the same straight line, ensuring that the liquid-fluid purging effect is applied to the entire width of the strip 5, thus guaranteeing the liquid removal effect. The regulating valve assembly can control the rate at which the compressed gas enters the jet pipe 21, thereby controlling the speed of the high-speed airflow ejected from the vents 22.

[0042] like Figure 3As shown, the end of the air jet pipe 21 is detachably provided with a blocking structure 3, which can block at least one air hole 22 at the two ends of the air jet pipe 21, and the spacing between the two blocking structures 3 is adapted to the width of the strip 5. The blocking structure 3 comprises a blocking ring 31 provided at the two ends of the air jet pipe 21 respectively, the blocking ring 31 and the air jet pipe 21 are mutually adapted to be circular, the inner wall of the blocking ring 31 is provided with an internal thread, and the outer wall of the air jet pipe 21 is provided with an external thread extending from the end to the center, and the internal thread and the external thread are connected by engagement.

[0043] Specifically, the blocking structure 3 is used to block a plurality of air holes 22 counted from the end to the center, so that the distribution length of the normally opened air holes 22 is adapted to the width of the strip 5, which improves the utilization rate of the cost of compressed gas, and the setting of the blocking structure 3 has flexible detachability, which can be selected and set according to the actual situation, improving the practicability. The blocking ring 31 of the embodiment is provided on the air jet pipe 21 by thread, and the position of the blocking ring 31 on the air jet pipe 21 can be adjusted by rotating the blocking ring 31. When the blocking ring 31 is not needed, it can be kept at the outermost end, and when the blocking is needed, the blocking ring 31 can be rotated inward. The blocking ring 31 is located radially outside the air hole 22 to achieve the effect of closing the air hole 22, which is convenient to operate.

[0044] As shown in the figure, Figure 1 The overstrip roller 1 comprises a first over roller 11 and a second over roller 12 rotatably connected to the main frame, the first over roller 11 is located on the downstream side of the strip 5 transmission and is higher than the second over roller 12, the air jet structure 2 is arranged on the main frame and located between the first over roller 11 and the second over roller 12, and the output port is obliquely downward to the strip 5. The overstrip roller 1 further comprises a third over roller 13 rotatably connected to the main frame, the third over roller 13 is located on the upstream side of the second over roller 12 and is higher than the second over roller 12; the second over roller 12 is located in the liquid tank 4 and is partially or completely submerged below the liquid level of the liquid tank 4, the strip 5 transmission passes below the second over roller 12, and the strip 5 passes through the liquid of the liquid tank 4.

[0045] Specifically, the strip 5 is wound and connected to the first over roller 11 and the second over roller 12, and there is a height difference between the first over roller 11 and the second over roller 12, so that the strip 5 also assumes an inclined state, and the downstream side of the strip 5 transmission is located at a high position, which helps the attached liquid to be smoothly blown away under the action of gravity and the high-speed airflow obliquely output by the air jet structure 2. The strip 5 passes through the third over roller 13, the second over roller 12 and the first over roller 11 in turn, and the strip 5 assumes a U-shaped transmission between the overstrip rollers 1, and the lowest position of the strip 5 transmission passes through the liquid of the liquid tank 4, meeting the corresponding liquid impregnation processing requirements.

[0046] Specific working principle: the strip 5 is driven on the passing roller 1, and sequentially passes through the third passing roller 13, the second passing roller 12, the liquid in the liquid tank 4, the air jet structure 2 and the first passing roller 11. After passing through the liquid, the strip 5 is attached with a certain liquid flow. The air holes 22 of the air jet pipe 21 output high-speed air flow, which blows the liquid flow downward. The treated strip 5 passes through the first passing roller 11 and is transmitted to the subsequent drying mechanism.

[0047] Embodiment 2

The outer end of each independent cavity 24 is connected to the compressed gas generating assembly through a compression pipeline.

[0050] Specifically, the inner cavity of the air jet pipe 21 is divided into two parts by the partition plate 23. Each independent cavity 24 is connected to the compressed gas generating assembly, which is conducive to the output of high-speed air flow from each air hole 22 of the air jet pipe 21, and ensures that the entire width of the strip 5 can be effectively blown by the liquid.

[0051] Embodiment 3

[0052] The specific working principle of the embodiment is basically the same as that of embodiment 1, and the difference lies in the plugging structure 3.

[0053] Specific embodiments are shown in the drawings Figure 5 As shown, the plugging structure 3 includes a closed ring 31 arranged at both ends of the air jet pipe 21. The closed ring 31 and the air jet pipe 21 are adaptively shaped and are both circular. The closed ring 31 is slidingly sleeved on the air jet pipe 21. The side of the closed ring 31 away from the air hole 22 is provided with a limiting bolt 32, which is engaged with a connecting screw hole 33 of the closed ring 31 and abuts against the outer side wall of the air jet pipe 21. The inner side wall of the closed ring 31 away from the connecting screw hole 33 covers the outer side of the air hole 22.

[0054] Specifically, the closed ring 31 of the embodiment is sleeved on the air jet pipe 21 and can move axially to adjust the number of air holes 22 to be closed and is fixed by the limiting bolt 32. The limiting bolt 32 is located on the side away from the air hole 22. As it is continuously screwed in, the closed ring 31 is pulled to the side of the limiting bolt 32, so that the closed ring 31 is stably covered on the outer side of the air hole 22, and the closing effect is good.
