Description

TECHNICAL FIELD

[0001] The utility model relates to aluminum foil production equipment technical field, especially a kind of aluminum powder slurry coating device for sintered foil production. BACKGROUND

[0002] Aluminum foil is widely used in food, beverage, cigarette, medicine, photographic plate, household commodity and other receipts due to its excellent characteristics, and is usually used as its packaging material. There are mainly two kinds of production methods of aluminum foil, sintering method and rolling method, wherein the raw materials need to be evenly applied on the substrate according to the state of the raw materials, and the application method is also different. Solid powder usually adopts hot pressing method, and liquid slurry is attached to the substrate by brushing method. However, the application of the existing brushing device is unstable, and the raw material film thickness is often uneven, thereby affecting the sintering quality. SUMMARY

[0003] The utility model aims at providing a kind of aluminum powder slurry coating device for sintered foil production, to solve the problem of uneven application of aluminum powder slurry in the prior art, thereby affecting the sintering quality.

[0004] To achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a kind of aluminum powder slurry coating device for sintered foil production, comprising two symmetrical walking mechanisms, a mounting bracket is arranged above the walking mechanism, a fixed plate is fixedly connected between the mounting bracket and the walking mechanism, and the walking mechanism, the fixed plate and the mounting bracket jointly enclose a U-shaped channel;A storage tank is arranged in the mounting bracket, a slurry inlet is arranged at the top of the storage tank, a slurry outlet is arranged at the bottom of the storage tank, and a baffle is installed at the slurry outlet;A leveling roller and a scraper are sequentially arranged at the bottom of the mounting bracket, the leveling roller is close to the slurry outlet, and the scraper is away from the slurry outlet.

[0005] Optionally, the leveling roller is provided with a plurality of roots, and the plurality of roots are arranged in two rows, and the two rows of leveling rollers are arranged in staggered manner.

[0006] Optionally, the scraper is provided with two pieces, which are respectively referred to as first scraper and second scraper, the length of the first scraper is greater than the length of the second scraper, and the second scraper is closer to the leveling roller than the first scraper.

[0007] Optionally, the first scraper and the second scraper are slidingly connected to the mounting bracket, the top of the first scraper and the second scraper passes through the mounting bracket and is fixed by a fixed clamp, the fixed clamp is fixedly connected to the top of the mounting bracket, and a scale is arranged on the first scraper and the second scraper.

[0008] Optionally, the bottom of the first scraper and the second scraper is provided with an inclined surface.

[0009] Optionally, the walking mechanism comprises a walking beam, a walking wheel is installed at the bottom of the walking beam, and a driving motor for driving the walking wheel to rotate is installed at the outer side of the walking beam.

[0010] The aluminum powder slurry coating device for sintered foil production of this utility model has the following advantages:

[0011] (1) When the device is in use, it spans across both sides of the substrate. The raw material falls onto the substrate from the slurry outlet. Then the raw material is initially smoothed by the leveling roller and further smoothed by the scraper, so that the raw material is evenly coated on the substrate, ensuring the stability of the subsequent sintering quality.

[0012] (2) When the substrate width is large, a single leveling roller may encounter greater resistance when smoothing the raw material, which may affect the normal movement of the device. Setting multiple leveling rollers can disperse the resistance when smoothing the raw material, ensuring the initial smoothing effect without affecting the movement of the device.

[0013] (3) The first scraper and the second scraper can scrape the material twice, making the thickness of the raw material film more uniform. Attached Figure Description

[0018] The present invention will be further described below with reference to the accompanying drawings, in which the following description will use the accompanying drawings as references. Figure 1 Using the direction in the center as a reference, the coating device moves from left to right.

[0019] like Figures 1-4 As shown, an aluminum powder slurry coating device for sintered foil production includes two symmetrically arranged traveling mechanisms 1. A mounting frame 2 is positioned above each traveling mechanism 1, and a fixing plate 3 is fixedly connected between the mounting frame 2 and the traveling mechanism 1. The traveling mechanism 1, the fixing plate 3, and the mounting frame 2 together form a U-shaped channel. Each traveling mechanism 1 includes a traveling beam 4, with traveling wheels 5 mounted at the bottom of the traveling beam 4. A drive motor 6, which drives the traveling wheels 5 to rotate, is mounted on the outer side of the traveling beam 4. Driven by the drive motor 6, the device can move to the right at a uniform speed.

[0020] The right side inside the mounting frame 2 is provided with a storage box 7, the top of the storage box 7 is provided with a slurry inlet 8, the bottom of the storage box 7 is provided with a slurry outlet 9, a baffle (not shown in the figure) is installed at the slurry outlet 9, the baffle can adjust the size of the slurry outlet 9, so as to adjust the discharging rate of the slurry. The bottom of the mounting frame 2 is sequentially provided with a first scraper 10, a second scraper 11 and a plurality of leveling rollers 12 from left to right, the leveling rollers 12 are arranged in two rows, the two rows of leveling rollers 12 are arranged in a staggered manner, the leveling rollers 12 can cover the width of the substrate 15, and the staggered arrangement of the leveling rollers 12 can disperse the resistance when the raw material is initially leveled, so as to avoid affecting the movement of the device. The first scraper 10 and the second scraper 11 are vertically and slidingly connected to the mounting frame 2, the top of the first scraper 10 and the second scraper 11 passes through the mounting frame 2 and is fixed by a fixing clamp 13, the fixing clamp 13 is fixedly connected to the top of the mounting frame 2, the first scraper 10 and the second scraper 11 are provided with scales, the fixing clamp 13 is opened, the length of the first scraper 10 and the second scraper 11 extending out of the mounting frame 2 can be adjusted, so as to adjust the coating thickness of the raw material film 16. The bottom of the first scraper 10 and the second scraper 11 is provided with an inclined surface, which is helpful to reduce the resistance when the raw material is leveled, so that the coating of the raw material is more uniform.

[0021] The substrate 15 is horizontally placed on the operation table 14, the coating device is horizontally arranged above the substrate 15, and the two fixing plates 3 are arranged close to the two sides of the substrate 15. The distance between the first scraper 10 and the second scraper 11 and the substrate 15 is adjusted, that is, the gradient of the thickness of the raw material film 16 is set, then the baffle is opened, the slurry falls on the substrate 15, and the driving motor 6 drives the device to move at a constant speed to the right. During the movement of the device, first, the leveling rollers 12 contact the slurry, and the accumulated slurry is initially leveled on the substrate 15, then the second scraper 11 contacts the slurry, and the slurry is more uniformly spread on the substrate 15, and finally the first scraper 10 uniformly spreads the slurry into a raw material film 16 with a certain thickness. The multiple leveling and coating structures cooperate with each other, so that the raw material film 16 is uniform and the thickness is accurate, which is helpful to improve the quality of subsequent sintering operation.
