Description

Technical Field

[0001] This utility model relates to the field of emulsion coating preparation technology, specifically to a raw material conveying device for emulsion coating preparation. Background Technology

[0002] Emulsion coatings are a type of water-based coating. Their main component is polymer emulsion (such as acrylic ester, styrene-acrylic emulsion, etc.). The polymer particles in the emulsion form a continuous film during the coating drying process, thereby achieving protective and decorative functions. During the preparation of emulsion coatings, powder raw materials such as titanium dioxide, lithopone, and iron oxide pigments need to be added through a screw conveyor device.

[0003] Since most screw conveyors adopt a fixed height structure, the height of the discharge port cannot be adjusted. In actual production lines, different processing equipment and production layouts require the conveyor to have a certain degree of flexibility to adapt to different working heights. The fixed height design limits the versatility and flexibility of the device. Furthermore, the screw conveyor lacks a structure at the feed inlet for crushing agglomerated powder raw materials. When the agglomerated powder raw materials are sent into the emulsion coating mixing equipment, the agglomerated material is difficult to fully contact and disperse with other raw materials during mixing, resulting in uneven distribution of powder raw materials in the emulsion. Therefore, we propose a raw material conveying device for emulsion coating preparation to solve the above problems. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a raw material conveying device for emulsion coating preparation, which solves the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0006] A raw material conveying device for emulsion coating preparation includes a base, an mounting seat on top of the base, a conveying cylinder fixed on the mounting seat, two spiral augers rotatably connected inside the conveying cylinder via bearings, an adjustment mechanism for adjusting the material discharge height of the conveying cylinder on the top of the base, a feeding hopper fixed to the top of the base via two brackets, two corrugated hoses fixedly connected to the bottom of the feeding hopper, the bottom ends of the corrugated hoses being fixedly connected to the conveying cylinder, two rollers rotatably connected inside the feeding hopper via bearings, and a moving mechanism installed at the bottom of the base.

[0007] Furthermore, the adjustment mechanism includes two guide seats fixed to the top of the base. A limit shaft is rotatably connected between the inner walls of the two sides of one of the guide seats via a bearing. The mounting seat is fixed to the surface of the limit shaft. A lead screw is rotatably connected between the two guide seats via a bearing. A moving block is threaded onto the surface of the lead screw. A connecting frame is rotatably connected to the moving block via a pin. The top of the connecting frame is rotatably connected to the mounting seat via a pin. Two guide rods for limiting the moving block are fixed between the two guide seats. The moving block slides on the surface of the two guide rods.

[0008] Furthermore, the moving mechanism includes a surrounding plate fixed to the bottom of the base. Inside the surrounding plate are two horizontal plates. The side walls of each horizontal plate are rotatably connected to a worm gear via bearings. The other end of each worm gear is rotatably connected to the wall of the surrounding plate via bearings. The two worm gears rotate in opposite directions. Between the inner walls of the two sides of the surrounding plate are two rotating shafts rotatably connected via bearings. The surface of each rotating shaft is fixed with a worm wheel, which meshes with a corresponding worm gear. The surface of each rotating shaft is fixed with a rotating seat, and one side wall of each rotating seat is fixed with two rollers.

[0009] Furthermore, sprockets are fixed to the surfaces of both spiral augers, and the two sprockets are connected by chain drive. Transmission gears are fixed to the surfaces of both rollers, and the two transmission gears mesh with each other.

[0010] Furthermore, spiral sealing strips are fixed to the surfaces of both augers, and the spiral sealing strips are tightly fitted to the inner wall of the conveying cylinder.

[0011] Furthermore, two guide scrapers are fixed inside the feed hopper.

[0012] Compared with the prior art, the present invention provides a raw material conveying device for emulsion coating preparation, which has the following beneficial effects:

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

[0021] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown in the figure, an embodiment of this utility model discloses a raw material conveying device for emulsion coating preparation, including a base 1, an mounting seat 2 above the base 1, a conveying cylinder 3 fixed on the mounting seat 2, and two spiral augers 4 rotatably connected inside the conveying cylinder 3 via bearings. Spiral sealing strips 14 are fixed to the surfaces of both spiral augers 4, and the spiral sealing strips 14 are tightly fitted to the inner wall of the conveying cylinder 3, enhancing the tightness of the fit between the spiral sealing strips 14 and the inner wall of the conveying cylinder 3, thereby improving the conveying effect of powder raw materials. An adjustment mechanism 5 for adjusting the feeding height of the conveying cylinder 3 is provided at the top of the base 1. A feeding hopper 7 is fixed to the top of the base 1 via two supports 6. Two guide scrapers 15 are fixed inside the feeding hopper 7. The two guide scrapers 15 facilitate the dropping of raw materials fed into the feeding hopper 7 between two rollers 9 for crushing, and the guide scrapers 15 can also crush the rollers 9. The surface is cleaned to prevent raw materials from adhering to it and affecting the subsequent crushing effect. The bottom of the feed hopper 7 is connected and fixed with two corrugated hoses 8. The bottom ends of the corrugated hoses 8 are connected and fixed to the conveying cylinder 3. The inside of the feed hopper 7 is rotatably connected with two rollers 9 through bearings. The bottom of the base 1 is equipped with a moving mechanism 10. When using this raw material conveying device for emulsion coating preparation, when it is necessary to adjust the height of the discharge pipe of the conveying cylinder 3, the adjustment mechanism 5 can be activated to drive the mounting base 2 to tilt. After the mounting base 2 tilts, it can drive the conveying cylinder 3 to tilt to a certain angle. At this time, the height of the discharge pipe of the conveying cylinder 3 can be adjusted. Then, the powder raw material can be sent into the inside of the feed hopper 7. Subsequently, the raw material will enter the two cavities of the conveying cylinder 3 through the two corrugated hoses 8. The motor can be started to drive the two spiral augers 4 to rotate. At this time, the powder raw material can be conveyed to the discharge pipe of the conveying cylinder 3 and dropped.

[0022] like Figure 3As shown, in some embodiments, the adjusting mechanism 5 includes two guide seats 501 fixed to the top of the base 1. A limit shaft 502 is rotatably connected between the inner walls of the two sides of one of the guide seats 501 via a bearing. The mounting base 2 is fixed to the surface of the limit shaft 502. A lead screw 503 is rotatably connected between the two guide seats 501 via a bearing. A moving block 504 is threaded onto the surface of the lead screw 503. A connecting frame 505 is rotatably connected to the moving block 504 via a pin. The top of the connecting frame 505 is rotatably connected to the mounting base 2 via a pin. Two guide rods 506 for limiting the moving block 504 are fixed between the two guide seats 501. The moving block 504 slides on the two guide rods 506. On the surface, when in use, starting the self-locking motor can drive the lead screw 503 to rotate. After the lead screw 503 rotates, it will drive the moving block 504 to move. Under the action of the limiting shaft 502, it can rotate and limit one end of the mounting base 2. When the moving block 504 moves, with the cooperation of the connecting frame 505, it can drive the mounting base 2 to rotate around the limiting shaft 502 as the center. At this time, the conveying cylinder 3 can be tilted, thereby adjusting the height of its feeding tube. The two guide rods 506 can play an auxiliary support and limiting role for the moving block 504. When the lead screw 503 rotates and drives the moving block 504 to move, it can prevent the moving block 504 from rotating synchronously with the lead screw 503.

[0023] like Figure 1 and Figure 3 As shown, in some embodiments, the moving mechanism 10 includes a surrounding plate 1001 fixed to the bottom of the base 1. Two horizontal plates 1002 are fixed inside the surrounding plate 1001. Worms 1003 are rotatably connected to the side walls of each horizontal plate 1002 via bearings. The other ends of the worms 1003 are rotatably connected to the wall of the surrounding plate 1001 via bearings. The two worms 1003 rotate in opposite directions. Two rotating shafts 1004 are rotatably connected between the inner walls of the two sides of the surrounding plate 1001 via bearings. Worm wheels 1005 are fixed to the surface of each rotating shaft 1004, and each worm wheel 1005 meshes with a corresponding worm 1003. A rotating seat 1006 is fixed to the surface of each rotating shaft 1004, and two rotating seats 1006 are fixed to one side wall of each rotating seat 1006. The roller 1007, when in use, the self-locking dual-axis motor can drive the two worm gears 1003 with opposite rotation directions to rotate. After the two worm gears 1003 rotate, they will drive the two worm wheels 1005 to rotate in the opposite direction. After the worm wheels 1005 rotate in the opposite direction, they will drive the two rotating shafts 1004 to rotate. After the rotating shafts 1004 rotate, they will drive the rotating seat 1006 to rotate. At this time, after the rotating seat 1006 rotates, it can drive the roller 1007 to contact the ground and lift the base 1. Then the entire conveying device can be moved a short distance. After it has moved, the self-locking dual-axis motor can be started to drive the rotating seats 1006 on both sides to rotate and reset. Then the base 1 continues to support the entire device to make it more stable during use.

[0024] like Figure 2 and Figure 5 As shown, in some embodiments, sprockets 11 are fixed to the surfaces of both spiral augers 4, and the two sprockets 11 are connected by a chain 12. Transmission gears 13 are fixed to the surfaces of both rollers 9, and the two transmission gears 13 are meshed with each other. Through the cooperation of the sprockets 11 and the chain 12, a motor can synchronously drive the two spiral augers 4 to rotate synchronously. With the cooperation of the two transmission gears 13, a motor can simultaneously drive the two rollers 9 to rotate synchronously in opposite directions, thereby saving production costs.

[0025] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model 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.
