[0005] However, in actual use, due to factors such as the cooling rate during casting, the surface of the grid plate is uneven, affecting the quality. Summary of the Invention

[0006] The purpose of the present invention is to address the shortcomings of the existing technology. By setting up a cooling mechanism and a separation mechanism, efficient and uniform cooling of the grid during the forming process is achieved, so that the grid maintains a uniform thickness at each position after cooling and forming, thereby solving the technical problem of uneven surface of the grid caused by uneven cooling during the forming process.

[0007] In response to the above technical problems, the technical solutions adopted are as follows:

[0008] A lightweight and long-life lead-acid battery grid material casting device, comprising:

[0009] A casting mechanism, which is used to cast and shape the grid;

[0010] A cooling mechanism, which is arranged on one side of the casting mechanism and is used to cool the grid, and includes a primary cooling component and a secondary cooling component;

[0011] A separating mechanism is provided below the casting mechanism and is used to separate the grid from the casting mechanism.

[0012] Preferably, the casting mechanism includes a casting roller connected to the frame for forming the grid and driven to rotate by a motor. The casting roller is cylindrical and has casting lines on its surface. The inner wall gradually becomes thinner from the middle to the two end edges, and the cross-section presents a "thick in the middle and thin at both ends" shape.

[0013] Preferably, the casting mechanism also includes multiple groups of solenoid valves arranged above the casting roller and used to control the release of molten lead, a discharge port arranged below each group of solenoid valves and opened and closed according to the casting lines on the casting roller, and a scraper curtain arranged on the rotating side of the casting roller at the discharge port.

[0014] Preferably, the cooling mechanism is arranged behind the casting mechanism on the rotation path of the casting roller and is used to rapidly cool the surface of the molten lead. The primary cooling component includes a heat-absorbing part arranged behind the scraping curtain and a temperature-reducing part arranged behind the heat-absorbing part. The heat-absorbing part includes a rotating shaft arranged above the casting roller and rotating synchronously with the casting roller through a transmission belt, a plurality of scraper groups arranged on the rotating shaft, a sliding frame arranged in the middle of each group of scrapers and connected to the rotating shaft at both ends in a radial sliding manner, a hose rotatably connected to the sliding frame at both ends and with a phase change energy storage material arranged inside, and a spring arranged between the sliding frame and the driving shaft.

[0015] Preferably, the cooling element includes a group of No. 1 fans arranged behind the heat absorbing element, and a group of nozzles arranged in the air inlet area behind the No. 1 fan. The horizontal position of the No. 1 fan is lower than the horizontal position of the heat absorbing element and is tilted so that the airflow released by the No. 1 fan is directed toward the heat absorbing element. The nozzles spray water in a fan shape to form a water curtain, and the water curtain is located in the negative pressure area of ​​the No. 1 fan, and the spray direction of the water flow is toward the casting roller below.

[0016] Preferably, the secondary cooling assembly is arranged below the primary cooling assembly, including multiple groups of No. 2 fans arranged below the No. 1 fan, and the No. 2 fans are arranged at an angle so that the air flow is inclined downward toward the casting roller.

[0017] Preferably, the secondary cooling assembly also includes a water tank arranged below the side of the second fan, a filter screen arranged at the bottom of the water tank, multiple groups of nozzles arranged in the casting roller and connected to the bottom of the water tank, and a water pool arranged below the casting roller.

[0018] Preferably, the separation mechanism includes an arc-shaped plate arranged below the casting roller and used to separate the grid from the casting lines, a No. 3 fan arranged behind the arc-shaped plate and allowing the airflow to flow directly toward the arc-shaped plate, and a cleaning member arranged between the arc-shaped plate and the No. 3 fan.

[0019] Preferably, the cleaning element includes a roller rotatably connected to the bottom of the casting roller, multiple sets of sliding rods slidably connected to the roller along the radial direction of the roller, a brush fixed to the outer end of the sliding rod and vibrated by a motor, a cam rod arranged in the middle of the roller, and a spring arranged between the roller and the sliding rod.

[0020] As another preferred embodiment, the production process of the lightweight and long-life lead-acid battery grid material casting equipment includes the following steps:

[0021] Step 1: Casting and forming step: the casting roller rotates, and the solenoid valve cooperates with the discharge port to release the lead liquid onto the casting pattern of the casting roller to form the grid;

[0022] Step 2: Step cooling:

[0023] a. Primary cooling: As the casting roller rotates, the molten lead moves out of the scraping curtain, and the rotating shaft rotates synchronously. The hose installed on the rotating shaft adheres to the surface of the casting roller, and the internal phase change material absorbs heat to cool the surface of the molten lead. At the same time, the scraper rotates to scrape off the excess molten lead on the surface of the casting roller. At the same time, the No. 1 fan cooperates with the nozzle to blow air carrying tiny droplets to the surface of the molten lead, further accelerating the cooling rate and achieving rapid cooling of the grid surface.

[0024] b. Secondary cooling: After the primary cooling, the lead liquid continues to move, and the water sprayed from the nozzle adheres to the surface of the casting roller and is cooled again in conjunction with the No. 2 fan. At the same time, excess water drops into the water tank and is sprayed onto the inner wall of the casting roller through the nozzle to achieve cooling inside the grid;

[0025] Step three is the separation and cleaning step. After being completely cooled, the grid is separated from the casting roller through the arc plate to achieve output. The casting roller continues to move, and the cleaning part rotates synchronously to clean the surface of the casting roller to prevent residual lead liquid from affecting subsequent production.

[0026] Beneficial effects of the present invention:

[0027] (1) The present invention provides a cooling mechanism to cool the grid plate by combining air cooling with water cooling. This improves the cooling rate of the grid plate and ensures that the cooling rate of each position of the grid plate during the cooling process is consistent, thereby ensuring that the grid plate will not deform during the cooling process due to differences in cooling rates, resulting in surface unevenness, cracking, or distortion.

[0028] (2) The present invention provides a first cooling assembly and a second cooling assembly to perform step-by-step cooling on the grid plate. The first cooling assembly is used to rapidly cool the surface of the grid plate, while the second cooling assembly is used to thoroughly cool the interior of the grid plate. This improves the cooling rate of the grid plate while also improving the cooling effect and reducing the impact of uneven cooling on the quality of the grid plate.

[0029] (3) The present invention uses a separation mechanism to separate the grid plate and clean the surface of the casting roller at the same time. The separation mechanism can effectively reduce the adhesion of waste and water stains on the grid plate. By cleaning the surface of the casting roller, waste is prevented from mixing into the lead liquid during casting, which affects the quality of the grid plate. BRIEF DESCRIPTION OF THE DRAWINGS

[0044] The technical solutions in the embodiments of the present invention are clearly and completely described below with reference to the accompanying drawings.

[0045] Example 1

[0046] like Figure 1 As shown, a lightweight and long-life lead-acid battery grid material casting device includes:

[0047] Casting mechanism 1, the casting mechanism 1 is used to cast and shape the grid;

[0048] A cooling mechanism 2 is provided on one side of the casting mechanism 1 and is used to cool the grid. The cooling mechanism 2 includes a primary cooling component 21 and a secondary cooling component 22;

[0049] A separating mechanism 3 is provided below the casting mechanism 1 and is used to separate the grid from the casting mechanism 1 .

[0050] In this embodiment, by providing a cooling mechanism 2 and a separation mechanism 3, the grid is cooled quickly and evenly, and various means are used to keep the grid flat and even during the forming process, thereby improving the quality of the formed grid.

[0051] In detail, the lead liquid is evenly and accurately released into the casting lines on the surface of the casting roller 11 through casting. As the casting roller 11 rotates, the lead liquid passes through the primary cooling component 21 for rapid surface cooling, and then passes through the secondary cooling component 22 to evenly and thoroughly cool the interior of the lead liquid. Subsequently, the lead liquid is separated and demoulded through the separation mechanism 3, and the casting roller 11 is cleaned.

[0052] It should be noted that, with regard to the cooling of the lead liquid, the different cooling rates can easily lead to differences in the lead liquid at various positions during the cooling process, resulting in an uneven surface and affecting the overall quality of the grid.

[0053] It is worth mentioning that, by setting the separation mechanism 3 , the casting roller 11 is cleaned to prevent the lead liquid from remaining on the casting roller 11 and affecting the subsequent forming of the lead liquid.

[0054] Further, if Figure 2 As shown, the casting mechanism 1 includes a casting roller 11 connected to the frame for forming the grid and driven by a motor to rotate. The casting roller 11 is cylindrical and has casting lines on the surface. The inner wall gradually becomes thinner from the middle to the edges of both ends, and the cross-section presents a "thick in the middle and thin at both ends" shape.

[0055] In this embodiment, the casting roller 11 is provided to achieve the shaping and cooling of the lead liquid, which is conducive to adapting to the cooling mechanism 2 and better completing the cooling of the grid.

[0056] In detail, the casting roller 11 rotates, and the lead liquid is released onto the casting lines on the surface of the casting roller 11, so that the lead liquid can be uniformly formed. As the casting roller 11 rotates, it is cooled and separated in sequence. At the same time, the shape of the inner wall of the casting tube is conducive to cooling by the cooling mechanism 2.

[0057] It should be noted that the inner wall of the casting roller 11 gradually becomes thinner from the middle to the two ends, so that water can flow out from the two ends of the middle phase.

[0058] It is worth mentioning that the casting roller 11 is cylindrical and hollow inside. On the one hand, hot oil is covered in the mold of the casting roller 11 through a pipeline, which reduces energy consumption and demoulding time compared with the original. On the other hand, it is beneficial to its own heat dissipation and saves materials.

[0059] Further, if Figure 3 As shown, the casting mechanism 1 also includes multiple sets of solenoid valves 12 located above the casting rollers 11 and used to control the release of molten lead, discharge ports 13 located below each set of solenoid valves 12 and opening and closing according to the casting pattern on the casting rollers 11, and a scraping curtain 14 located on the rotating side of the discharge ports 13 on the casting rollers 11.

[0060] In this embodiment, by providing the solenoid valve 12 and the discharge port 13, the lead liquid is evenly released onto the casting lines on the surface of the casting roller 11, the release amount of the lead liquid is accurately controlled, and the lead liquid can evenly fill the casting lines.

[0061] In detail, as the casting roller 11 rotates, the solenoid valve 12 controls the release of the molten lead, and the molten lead is accurately released onto the casting pattern through the discharge port 13. After the release of the molten lead is completed, the scraping curtain 14 is passed to make the surface of the molten lead more uniform.

[0062] It should be noted that, since the casting pattern is mesh-shaped, the discharge port 13 is provided with multiple groups of material ports for lateral release and longitudinal release respectively, so as to achieve the matching of the discharge port 13 with the casting pattern, and accurately release the molten lead into the casting pattern to avoid overflow or unevenness of the molten lead.

[0063] Further, if Figure 4 、 Figure 5 As shown, the cooling mechanism 2 is arranged behind the casting mechanism 1 on the rotation path of the casting roller 11 and is used to rapidly cool the surface of the molten lead. The primary cooling component 21 includes a heat absorbing member 211 arranged behind the scraping curtain 14 and a temperature reducing member 212 arranged behind the heat absorbing member 211. The heat absorbing member 211 includes a rotating shaft 2111 arranged above the casting roller 11 and rotating synchronously with the casting roller 11 through a transmission belt, a plurality of scraper groups 2112 arranged on the rotating shaft 2111, a sliding frame 2113 arranged in the middle of each group of scraper 2112 and connected to the rotating shaft 2111 at both ends in a radial sliding manner, a hose 2114 rotatably connected to the sliding frame 2113 at both ends and provided with a phase change energy storage material, and a spring arranged between the sliding frame 2113 and the driving shaft.

[0064] In this embodiment, by providing the scraper 2112 and the hose 2114 , on the one hand, the surface of the molten lead is cooled, and on the other hand, the molten lead that may remain on the surface of the casting roller 11 is cleaned.

[0065] In detail, the casting roller 11 rotates and the rotating shaft 2111 rotates synchronously. During the rotation of the rotating shaft 2111, the hose 2114 is attached to the casting roller 11. A phase change energy storage material is provided in the hose 2114 to absorb heat and cool the surface of the casting roller 11. At the same time, a scraper 2112 is provided to rotate with the rotating shaft 2111 to scrape off any excess lead liquid that may exist on the surface of the casting roller 11.

[0066] It should be noted that the hose 2114 can be made of a good thermal conductive material such as rubber to facilitate the internal phase change energy storage material to absorb heat.

[0067] It is worth mentioning that, under the action of the spring, the hose 2114 can fit on the surface of the casting roller 11 and rotate, so that the phase change energy storage material inside the hose 2114 can fully absorb heat, which is conducive to cooling.

[0068] Further, if Figure 4 As shown, the cooling element 212 includes a group of fans 2121 arranged behind the heat absorbing element 211, and a group of nozzles 2122 arranged in the air inlet area behind the fan 2121. The horizontal position of the fan 2121 is lower than the horizontal position of the heat absorbing element 211 and is tilted so that the airflow released by the fan 2121 is directed toward the heat absorbing element 211. The nozzles 2122 spray water in a fan shape to form a water curtain, and the water curtain is located in the negative pressure area of ​​the fan 2121, and the spray direction of the water flow is toward the casting roller 11 below.

[0069] In this embodiment, by providing a No. 1 fan 2121 and a nozzle 2122, a combination of air cooling and water cooling is achieved, which effectively accelerates the cooling of the surface of the casting roller 11 and prevents the lead liquid from flowing during the cooling process.

[0070] In detail, fan No. 1 2121 and nozzle 2122 are started, and fan No. 1 2121 outputs airflow in the direction of heat absorption element 211. On the one hand, air cooling is used to increase the cooling rate of the lead liquid surface, while allowing the phase change material after absorbing heat to release heat as quickly as possible to carry out subsequent heat absorption work; on the other hand, fan No. 1 2121 can extract tiny liquids released by nozzle 2122 in the rear negative pressure area into the airflow. As the airflow moves to the position of the heat absorption element 211, the tiny droplets can assist the heat absorption element 211 to absorb heat better, and at the same time, they are easily evaporated under the action of the airflow, further improving the efficiency of heat absorption cooling.

[0071] It should be noted that the nozzle 2122 forms a water curtain in the negative pressure area of ​​the No. 1 fan 2121, which plays a role in blocking dust. Most of the dust in the air is sprayed onto the surface of the casting roller 11 below along with the droplets sprayed from the nozzle 2122, making the gas blown out by the No. 1 fan 2121 relatively cleaner, avoiding dust from adhering to the surface of the lead liquid that has not been completely cooled.

[0072] It is worth mentioning that, by setting the No. 1 fan 2121, the airflow blown out by the No. 1 fan 2121 is utilized to slow down the flow of the lead liquid when it is not completely cooled, so that the grid is more uniform.

[0073] Further, if Figure 6 As shown, the secondary cooling assembly 22 is arranged below the primary cooling assembly 21, and includes multiple groups of No. 2 fans 221 arranged below the No. 1 fan 2121. The No. 2 fans 221 are tilted so that the air flow tilts downward toward the casting roller 11.

[0074] In this embodiment, the second fan 221 is provided in cooperation with the nozzle 2122 to achieve thorough cooling of the lead liquid.

[0075] In detail, the lead liquid continues to rotate after passing through the primary cooling component 21. At this time, a large amount of water is attached to the surface. The wind from the second fan 221 is combined with the water to accelerate the thorough cooling of the lead liquid. At the same time, the second fan 221 is tilted downward, which is conducive to the excess water flowing down as quickly as possible, reducing the water adhesion on the surface of the grid during subsequent separation.

[0076] It is worth mentioning that the setting of the second fan 221 accelerates the evaporation of water and the cooling of the lead liquid. At the same time, the water and wind are more uniform, avoiding surface distortion of the lead liquid due to different cooling rates at different positions when the lead liquid is completely cooled.

[0077] Further, if Figure 6 、 Figure 7 As shown, the secondary cooling component 22 also includes a water tank 222 arranged below the side of the second fan 221, a filter screen arranged at the bottom of the water tank 222, multiple groups of nozzles 223 arranged in the casting roller 11 and connected to the bottom of the water tank 222, and a water pool 224 arranged below the casting roller 11.

[0078] In this embodiment, by providing a water tank 222 and a nozzle 223, water on the outer surface of the casting roller 11 is recovered, and at the same time, the inner surface of the casting roller 11 is cooled to accelerate the uniform cooling of the lead liquid.

[0079] In detail, under the action of the No. 2 fan 221, the water falls into the water tank 222, is filtered through the filter net and is extracted into the nozzle 223 again, and is sprayed on the inner surface of the casting roller 11 through the nozzle 223. The water slides down the inner surface of the casting roller 11, flows out of the casting roller 11 from both sides, and drips into the water pool 224.

[0080] It should be noted that the nozzle 2122 continuously sprays water toward the surface of the casting roller 11. As the casting roller 11 rotates, the water absorbs heat and drips from the casting pipe into the water tank 222, and is sprayed onto the inner wall of the casting roller 11 through the nozzle 223. Based on the shape of the inner wall of the casting roller 11, the water flows downward on the inner wall of the casting roller 11 and moves toward both ends, taking away the heat on the inner wall of the casting roller 11, thereby cooling the inside of the molten lead and making the cooling of the molten lead more uniform, thorough and rapid.

[0081] It is worth mentioning that the water pool 224 provided below can realize the reuse of water and reduce consumption.

[0082] Further, if Figure 8As shown, the separation mechanism 3 includes a curved plate 31 arranged below the casting roller 11 and used to separate the grid from the casting lines, a third fan 32 arranged behind the curved plate 31 and allowing the airflow to flow directly towards the curved plate 31, and a cleaning member 33 arranged between the curved plate 31 and the third fan 32.

[0083] In this embodiment, the arc plate 31 and the third fan 32 are provided to achieve separation of the formed rear grille.

[0084] In detail, as the casting roller 11 rotates, the arc plate 31 extends into the casting lines on the surface of the casting roller 11, and uses its own arc shape to separate the grid from the casting lines on the surface of the casting roller 11. The No. 3 fan 32 is used to reduce the adhesion of water on the grid surface through wind, and on the other hand, the excess lead liquid that is stuck to the grid surface with water and is hung by the scraper 2112 is separated from the grid.

[0085] It should be noted that after the scraper 2112 scrapes off the lead liquid on the surface of the casting roller 11, due to the influence of the water bottom, the waste sticks to the surface of the casting roller 11 and continues to move downward. Under the action of the No. 3 fan 32, the wind force is used to blow the waste off before the grid is detached, causing the waste to fall into the water tank 222.

[0086] It is worth mentioning that the third fan 32 can use wind force to make the water fall above the water tank 222, thereby reducing the adhesion of water on the grid plate.

[0087] Further, if Figure 9 As shown, the cleaning member 33 includes a roller 331 rotatably connected to the bottom of the casting roller 11, a plurality of slide rods 332 slidingly connected to the roller 331 along the radial direction of the roller 331, a brush 333 fixed to the outer end of the slide rod 332 and vibrated by a motor, a cam rod 334 arranged in the middle of the roller 331, and a spring arranged between the roller 331 and the slide rod 332.

[0088] In this embodiment, the sliding rod 332 and the brush 333 are provided to clean the surface of the casting roller 11, especially the inside of the casting lines, to prevent the grid from remaining during the separation process and affecting subsequent production and molding.

[0089] In detail, the roller 331 rotates synchronously with the casting roller 11. Under the action of the cam, the slide bar 332 slides and extends into the casting line. Under the action of the motor, the brush 333 vibrates to clean the inside of the line.

[0090] It is worth mentioning that since there are water stains remaining on the surface of the casting roller 11, it is easier to clean it with a brush 333.

[0091] Example 2

[0092] like Figure 9-13As shown, the components identical or corresponding to those in the first embodiment are designated by the corresponding reference numerals in the first embodiment. For simplicity, only the differences from the first embodiment are described below. The second embodiment differs from the first embodiment in that:

[0093] Further, if Figure 9-13 As shown, the production process of the lightweight and long-life lead-acid battery grid material casting equipment is characterized by comprising the following steps:

[0094] Step 1: Casting and forming step: the casting roller 11 rotates, and the solenoid valve 12 cooperates with the discharge port 13 to release the lead liquid onto the casting pattern of the casting roller 11 to form the grid;

[0095] Step 2: Step cooling:

[0096] a. Primary cooling: As the casting roller 11 rotates, the molten lead moves out of the scraping curtain 14, and the rotating shaft 2111 rotates synchronously. The hose 2114 provided on the rotating shaft 2111 adheres to the surface of the casting roller 11, utilizing the internal phase change material to absorb heat, cooling the surface of the molten lead. Simultaneously, the scraper 2112 rotates to scrape off excess molten lead from the surface of the casting roller 11. Simultaneously, the No. 1 fan 2121 cooperates with the nozzle 2122 to blow air carrying tiny droplets toward the surface of the molten lead, further accelerating the cooling rate and achieving rapid cooling of the grid surface.

[0097] b. Secondary cooling: After the primary cooling, the lead liquid continues to move. The water sprayed from the nozzle 2122 adheres to the surface of the casting roller 11 and is cooled again by the second fan 221. At the same time, excess water drops into the water tank 222 and is sprayed onto the inner wall of the casting roller 11 through the nozzle 223 to achieve cooling inside the grid.

[0098] Step three is the separation and cleaning step. After being completely cooled, the grid is separated from the casting roller 11 through the arc plate 31 to achieve output. The casting roller 11 continues to move, and the cleaning part 33 rotates synchronously to clean the surface of the casting roller 11 to prevent residual lead liquid from affecting subsequent production.
