Description

Technical Field

[0001] This utility model belongs to the field of quartz crucible synthesis technology, specifically relating to a device for uniformly spreading quartz sand in quartz crucible synthesis. Background Technology

[0002] The quartz sand uniform spreading device for quartz crucible synthesis is mainly used in the quartz crucible synthesis process to transport a fixed amount of quartz sand to the mold or other location to facilitate the production and synthesis of the quartz crucible. Currently, the uniform spreading device mainly suffers from the following consensus-based shortcomings:

[0003] In traditional quartz crucible synthesis, when quartz sand needs to be spread, the required discharge width of traditional quartz sand varies. If the discharge width of the quartz sand is directly adjusted, the quartz sand will accumulate on both sides of the outlet, thus affecting the uniformity of the quartz sand. Traditional spreading devices cannot efficiently adjust the discharge width of the quartz sand after spreading while maintaining uniform spreading. Utility Model Content

[0004] The purpose of this invention is to provide a device for uniformly spreading quartz sand in quartz crucible synthesis, which aims to solve the problem in the prior art that it is impossible to adjust the discharge width of quartz sand after spreading it while maintaining uniform spreading of quartz sand more efficiently.

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

[0006] A device for uniformly spreading quartz sand in quartz crucible synthesis includes two outer frames. An inner frame is slidably connected to the inner wall of the bottom of the two outer frames. Two conveyor wheels are rotatably connected to the inner side wall of the inner frame. A conveyor belt is fitted around the outer side of the two conveyor wheels. Two limiting rings are fitted around the outer side of the conveyor belt. An outer frame is fixedly installed at the top of the two limiting rings. An inner plate is slidably connected to the inner side wall of the outer frame. The outer side of the inner plate is fixedly connected to the inner side wall of the inner frame. A storage box is fixedly installed on the inner wall of the top of the outer frame. A top frame is slidably connected to the inner wall of the bottom of the storage box. A top plate is fixedly installed on the inner wall of the bottom of the storage box. The outer side of the top plate is slidably connected to the inner side wall of the top frame. The tops of the outer frame and the inner plate are slidably connected to the inner walls of the top frame and the top plate, respectively. Two eccentric wheels are movably connected to the bottom of the inner frame. Two eccentric rods are rotatably connected to the bottom of the outer frame. The outer ends of the two eccentric rods are fixedly connected to the inner walls of the eccentric wheels.

[0007] In a preferred embodiment of this utility model, an active rod is rotatably connected to the inner wall of the storage box, a partition plate is fixedly installed on the outer side of the active rod, a driven rod is rotatably connected to one side of the outer frame, and a main gear and a secondary gear are fixedly installed at one end of the active rod and the driven rod, respectively, with the main gear meshing with the secondary gear.

[0008] In a preferred embodiment of this utility model, pulleys are fixedly installed at one end of both the driven rod and the eccentric rod, and a first transmission belt and a second transmission belt are respectively sleeved on the outer side of the pulleys.

[0009] In a preferred embodiment of this utility model, the inner sidewall of the inner frame is rotatably connected to a bidirectional lead screw, and the outer side of the bidirectional lead screw is threadedly connected to the inner side of the outer frame.

[0010] In a preferred embodiment of this invention, a limiting rod is fixedly installed at the bottom end of the inner frame, and the outer side of the limiting rod is slidably connected to the inside of the limiting ring.

[0011] In a preferred embodiment of this utility model, a first motor and a second motor are fixedly installed on the outer side of the storage box and the outer side of the inner frame, respectively. The output end of the first motor is fixedly connected to the other end of the drive rod, and the output end of the second motor is fixedly connected to one end of the conveyor wheel.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1) The outer frame drives the limiting ring to slide at the same distance in opposite directions on both sides of the conveyor belt, which makes it easier to adjust the discharge width of the quartz sand during the conveying process. The rotation of the eccentric wheel at the bottom of the inner frame allows the inner frame to move up and down continuously during the conveying of quartz sand, thereby increasing the uniformity of the quartz sand during the leveling process of the overall leveling device.

[0014] 2) By sliding the top frame on the outside of the top plate, the quartz sand inside the storage box can be prevented from falling out during the adjustment of the discharge width distance. The active rod drives the partition plate to rotate inside the storage box, so the output amount can be adjusted according to the amount of quartz sand output. Furthermore, the action of the main gear on the auxiliary gear ensures that the quartz sand is evenly spread during the feeding process, thereby improving the overall performance of the device.

[0022] 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.

[0023] Please see Figure 1-5 This utility model provides the following technical solution: a device for uniformly spreading quartz sand for quartz crucible synthesis, comprising two outer frames 1, an inner frame 2 slidably connected to the inner wall of the bottom end of the two outer frames 1, two conveying wheels 21 rotatably connected to the inner side wall of the inner frame 2, a conveyor belt 22 sleeved on the outer side of the two conveying wheels 21, two limiting rings 23 sleeved on the outer side of the conveyor belt 22, an outer frame 24 fixedly installed at the top of the two limiting rings 23, an inner plate 25 slidably connected to the inner side wall of the outer frame 24, and the outer side of the inner plate 25 fixedly connected to the inner side wall of the inner frame 2. Next, a storage box 3 is fixedly installed on the inner wall of the top of the outer frame 1. A top frame 34 is slidably connected to the inner wall of the bottom of the storage box 3. A top plate 35 is fixedly installed on the inner wall of the bottom of the storage box 3. The outer side of the top plate 35 is slidably connected to the inner side wall of the top frame 34. The tops of the outer frame 24 and the inner plate 25 are slidably connected to the inner walls of the bottom of the top frame 34 and the top plate 35, respectively. Two eccentric wheels 4 are movably connected to the bottom of the inner frame 2. Two eccentric rods 41 are rotatably connected to the bottom of the outer frame 1. The outer sides of the two ends of the two eccentric rods 41 are fixedly connected to the inner walls of the eccentric wheels 4.

[0024] In practical use, when spreading quartz sand, quartz sand can be added into the storage bin 3. When it is necessary to adjust the spreading width of the quartz sand, the outer frame 24 can slide on the outside of the inner plate 25, and the outer frame 24 drives the limiting ring 23 to slide on the outside of the conveyor belt 22. This allows the width of the conveyor belt 22 for conveying quartz sand to be adjusted, so that the quartz sand inside the storage bin 3 can be guided onto the conveyor belt 22 by the inner plate 25 after falling from the bottom. While conveying the quartz sand downward, the eccentric rod 41 can drive the eccentric wheel 4 on the inner frame. The rotation at the bottom of the inner frame 2 allows the inner frame 2 to continuously rise and fall at the bottom of the outer frame 1, thereby vibrating and evenly spreading the quartz sand on the conveyor belt 22. During the up-and-down vibration of the inner frame 2, the inner plate 25 slides up and down at the bottom of the top plate 35, and the outer frame 24 slides up and down with the top frame 34. While the outer frame 24 slides on the inner plate 25, it can simultaneously drive the top frame 34 to slide on the outside of the top plate 35, thereby preventing the quartz sand from leaking outwards while adjusting the width of the quartz sand and vibrating up and down, thus improving the overall effect of the device in spreading the quartz sand.

[0025] Preferably, the inner wall of the storage box 3 is rotatably connected to the drive rod 31, the outer side of the drive rod 31 is fixedly installed with the partition plate 32, the outer frame 1 is rotatably connected to the driven rod 5, and the drive rod 31 and the driven rod 5 are respectively fixedly installed with the main gear 33 and the auxiliary gear 51, and the main gear 33 meshes with the auxiliary gear 51.

[0026] In practical use, when the quartz sand inside the storage box 3 needs to be continuously fed, the active rod 31 can drive the partition plate 32 to rotate according to the feeding speed. At the same time as the active rod 31 rotates, the main gear 33 can drive the auxiliary gear 51 to rotate rapidly, and the auxiliary gear 51 can drive the driven rod 5 to rotate rapidly.

[0027] Preferably, pulleys 6 are fixedly installed at one end of both the driven rod 5 and the eccentric rod 41, and a first transmission belt 61 and a second transmission belt 62 are respectively sleeved on the outer side of the pulleys 6.

[0028] In practical use, while the driven rod 5 rotates rapidly, it can drive one of the eccentric rods 41 and eccentric wheels 4 to rotate through the pulley 6 and the first transmission belt 61. Then, through the action of the pulley 6 and the second transmission belt, it can drive the other eccentric wheel 4 and eccentric rod 41 to rotate synchronously in the same direction, thereby causing the inner frame 2 to vibrate up and down, which can evenly spread the quartz sand on it.

[0029] Preferably, the inner sidewall of the inner frame 2 is rotatably connected to a bidirectional lead screw 26, and the outer side of the bidirectional lead screw 26 is threadedly connected to the inner side of the outer frame 24.

[0030] In practical use, when it is necessary to adjust the output width of the quartz sand conveyed on the conveyor belt 22, the rotation of the bidirectional lead screw 26 can make the two opposing outer frames 24 slide synchronously in opposite directions.

[0031] Preferably, a limiting rod 27 is fixedly installed at the bottom of the inner frame 2, and the outer side of the limiting rod 27 is slidably connected to the inside of the limiting ring 23.

[0032] In practical use, while the limiting ring 23 slides through the outer frame 24, the limiting rod 27 at its bottom end can prevent the limiting ring 23 from deviating when sliding on the outside of the conveyor belt 22.

[0033] Preferably, a first motor 7 and a second motor 8 are fixedly installed on the outer side of the storage box 3 and the outer side of the inner frame 2, respectively. The output end of the first motor 7 is fixedly connected to the other end of the drive rod 31, and the output end of the second motor 8 is fixedly connected to one end of the conveyor wheel 21.

[0034] In practical use, the drive rod 31 can be driven by the first motor 7 to rotate inside the storage box 3, and the speed can be adjusted according to the required loading and unloading speed. The second motor 8 can drive the conveying wheel 21 to rotate, so as to adjust the conveying rate of quartz sand.

[0035] 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.
