Description

Technical Field

[0001] This utility model relates to the field of glass processing technology, and in particular to a thin-layer feeding device with adjustable height. Background Technology

[0002] Glass is an amorphous inorganic solid material, mainly composed of silicon dioxide. It is usually made by melting at high temperature and cooling rapidly. Glass processing is the process of changing the shape, properties, or surface condition of glass in optical glass or coated glass through physical or chemical methods. The particle size of glass powder affects the transmittance, refractive index, uniformity, and surface condition. In glass processing, sieving glass powder and metal powder is a key step in quality control. In colored glass, the particle size of metal oxide powder determines the color saturation and uniformity. Glass processing is a complex process from raw materials to finished products, and sieving glass powder and metal powder is a core link to ensure product quality, performance consistency, and process stability.

[0003] In existing technologies, when adding glass powder and metal powder during glass processing, the powder is usually added manually, which easily leads to uneven powder distribution. Furthermore, since different glass sizes vary, the powder is usually spread according to the operator's height, resulting in a relatively uniform spreading height. However, if the powder is spread laterally at a uniform height on a large glass surface, it can easily lead to excessively thick powder in some areas, resulting in uneven powder distribution, which significantly affects the quality of the glass after subsequent sintering and rolling. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing an adjustable-height thin-layer feeding device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a thin-layer feeding device with adjustable height, including a feeding frame, a sieve plate fixedly connected to the lower surface of the feeding frame, an opening and closing cover hinged to the upper surface of the feeding frame, and a feeding component provided below the feeding frame;

[0006] The feeding assembly includes two support frames, which are located below the feeding frame. One of the support frames has heat dissipation grooves on both sides. A stepper motor is fixedly installed inside the support frame, and a screw is fixedly connected to the output end of the stepper motor.

[0007] As a further description of the above technical solution:

[0008] The support frame is slidably connected to a connecting frame, one of which has a threaded groove inside, and the screw is threaded into the inside of the threaded groove.

[0009] As a further description of the above technical solution:

[0010] An electric cylinder is fixedly installed inside one of the connecting frames. The output end of the electric cylinder and one end of the other connecting frame are both fixedly connected to a connecting frame. Two limiting posts and two springs are fixedly connected to both sides of the delivery frame. The two limiting posts are slidably connected inside the connecting frame.

[0011] As a further description of the above technical solution:

[0012] Two of the springs are fixedly connected to one side of the connecting frame, and an electric cylinder is fixedly installed on the inner wall of one of the connecting frames. A blocking plate is fixedly connected to the output end of the electric cylinder.

[0013] As a further description of the above technical solution:

[0014] An inner rod is fixedly connected to one side of the baffle plate, and an outer rod is fixedly connected to the inner wall of the other connecting frame. The inner rod is slidably connected inside the outer rod.

[0015] As a further description of the above technical solution:

[0016] The dispensing frame is equipped with a stirring component, which includes multiple stirring frames rotatably connected inside the dispensing frame. One end of each stirring frame is fixedly connected to a gear, wherein two of the gears are meshed together.

[0019] This utility model has the following beneficial effects:

[0020] 1. This utility model, through the setting of the feeding component, utilizes the elastic force of the spring to facilitate the reciprocating shaking of the sieve plate for spreading powder, thereby facilitating the uniform spreading of powder. It also allows for adjustment of the spreading height of the sieve plate according to the height and surface width of the glass product. This helps to expand the spreading range when the sieve plate is raised, based on the principle of near-large and far-small, thus improving the uniformity of powder spreading and reducing the phenomenon of powder accumulation caused by lateral spreading at the same height. Furthermore, the baffle plate, after the powder has been spread to a suitable thickness, can block the downward movement of the powder below the sieve plate, promptly controlling the powder's descent and reducing the phenomenon of excessive spreading.

[0021] 2. By setting up a stirring component, this utility model uses a stirring frame to facilitate the stirring of powder inside the feeding frame, improves the looseness of powder inside the feeding frame, and helps to reduce the phenomenon of powder clumping above the sieve plate and clogging the sieve plate, making it difficult for the sieve plate to discharge material.

[0030] 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.

[0031] As attached Figure 1-6 As shown, one embodiment of the present invention is provided: a thin-layer feeding device with adjustable height, including a feeding frame 1, a screen plate 2 fixedly connected to the lower surface of the feeding frame 1, an opening and closing cover 3 hinged to the upper surface of the feeding frame 1, and a feeding component provided below the feeding frame 1.

[0032] The feeding assembly includes two support frames 4, which are located below the feeding frame 1. Each support frame 4 has heat dissipation slots 5 on both sides. A stepper motor 6 is fixedly installed inside the support frame 4. A screw 7 is fixedly connected to the output end of the stepper motor 6. When the screw 7 is rotated, it facilitates the longitudinal movement of the connecting frame 8 under the action of the threaded groove 9.

[0033] As attached Figure 3 As shown, a connecting frame 8 is slidably connected inside the support frame 4. One of the connecting frames 8 has a threaded groove 9 inside, which matches the thread of the screw 7. The screw 7 is threadedly connected inside the threaded groove 9. An electric cylinder 10 is fixedly installed inside one of the connecting frames 8. The output end of the electric cylinder 10 and one end of the other connecting frame 8 are both fixedly connected to a connecting frame 11.

[0034] As attached Figure 4 As shown, two limiting posts 12 and two springs 13 are fixedly connected to both sides of the delivery frame 1. The two limiting posts 12 are slidably connected inside the connecting frame 11, and the two springs 13 are fixedly connected to one side of the connecting frame 11, so that the delivery frame 1 has elasticity and can move back and forth.

[0035] As attached Figure 1 As shown, an electric cylinder 14 is fixedly installed on the inner wall of one of the connecting frames 8. A baffle plate 15 is fixedly connected to the output end of the electric cylinder 14, which acts as a blockage below the screen plate 2. An inner rod 17 is fixedly connected to one side of the baffle plate 15. An outer shell rod 16 is fixedly connected to the inner wall of the other connecting frame 8. The inner rod 17 is slidably connected inside the outer shell rod 16, which acts as a limit for the baffle plate 15.

[0036] As attached Figure 4 As shown, the inside of the feeding frame 1 is equipped with a stirring assembly, which includes multiple stirring frames 18 to facilitate stirring of the powder and reduce agglomeration. The multiple stirring frames 18 are rotatably connected inside the feeding frame 1. One end of the stirring frame 18 is fixedly connected to a gear 19, and two gears 19 are meshed to facilitate the two stirring frames 18 to rotate together. A worm gear 20 is fixedly connected to one side of the multiple gears 19. A variable speed motor 21 is fixedly installed on one side of the feeding frame 1. A rotating rod 22 is fixedly connected to the output end of the variable speed motor 21. Multiple worms 23 are fixedly connected to the outside of the rotating rod 22. The worms 23 are meshed with the worm gear 20, so that one output end can drive multiple stirring frames 18 to rotate relative to each other.

[0037] Working principle: During use, the glass workpiece to be processed is placed between two support frames 4. When the workpiece surface width is large and the height of the screen plate 2 needs to be adjusted, the stepper motor 6 is activated by the external controller, causing its output end to drive the screw 7 to rotate. With the connection of the threaded groove 9, it is easy to drive the connecting frame 8 to slide upward inside the support frame 4, thereby indirectly driving the height of the screen plate 2 to move upward and expand the spreading range. During spreading, the powder is put into the inside of the feeding frame 1. The controller is used to start the electric cylinder 10 and the variable speed motor 21. When the output end of the electric cylinder 10 extends and retracts, it pushes the connecting frame 11 to slide outside the two limit posts 12, squeezing the corresponding spring 13. After the spring 13 is compressed and generates elastic force, it rebounds due to the disappearance of the squeezing force. The thrust, under the action of the springs 13 on both sides, facilitates the reciprocating swaying of the feeding frame 1, which in turn causes the screen plate 2 to sway. At the same time, when the variable speed motor 21 is turned on, the output end will drive the rotating rod 22 to rotate, and the rotating rod 22 will drive multiple worm gears 23 to rotate. Under the meshing with the worm wheel 20, the worm wheel 20 will drive the corresponding gear 19 to rotate. Under the action of the meshing of two gears 19, multiple sets of stirring frames 18 will rotate relative to each other, thereby stirring and loosening the powder inside the feeding frame 1. Then, when the workpiece surface is covered with a suitable powder thickness, the electric cylinder one 10 is turned off and the electric cylinder two 14 is turned on, so that its output end drives the blocking plate 15 to move laterally below the screen plate 2 to block the powder screened out by the screen plate 2.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present 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. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
