The raw material proportioning device comprises a mixing barrel and a proportioning assembly. The top of the mixing barrel is fixed with a support frame. The proportioning assembly comprises a variable speed motor fixed to the top of the support frame. The outer side of the gear steering box is connected with a screw conveyor.

Description

Technical Field

[0001] The present invention relates to the technical field of glass processing, in particular to a raw material proportioning device for glass processing. Background Art

[0002] The main raw materials for glass processing are quartz sand, feldspar, dolomite, etc., which are mostly granular or powdery and have good fluidity. The raw materials need to be weighed when they are mixed so that the raw materials can be mixed according to the proportion to produce high-quality glass.

[0003] There are two main ways to mix glass raw materials. One is to use a weighing hopper to weigh the raw materials after a preset weight, and then introduce the raw materials in the hopper into a mixing barrel all at once. The other way is to directly inject raw materials exceeding a preset amount into the weighing hopper. As the hopper continues to inject material into the mixing barrel, the weight of the hopper decreases until the sensor detects that the weight of the hopper is the remaining weight after discharging the preset amount. However, of the above two methods, the former requires removing the excess raw materials when injecting raw materials exceeding the preset amount into the weighing hopper, and the latter is prone to interfere with the detection of the sensor due to the continuous movement of the raw materials, thereby affecting the accuracy, and thus resulting in errors in the actual injection amount of the raw materials. Summary of the Invention

[0007] Furthermore, the proportioning component also includes a first wheel disc, and the first wheel disc is fixed on the top of the hopper stirring shaft.

[0008] Furthermore, the proportioning assembly also includes a second wheel disc, and the end of the T-shaped bracket away from the hopper stirring shaft is rotatably connected to the second wheel disc.

[0009] Furthermore, the proportioning component also includes a transmission belt, and the second wheel disc and the outer wall of the first wheel disc are sleeved and meshed with the transmission belt.

[0010] Furthermore, the proportioning component also includes a second electric telescopic rod, and the second electric telescopic rod is plugged into the bottom of the second wheel disc.

[0011] Furthermore, the bottom of the second electric telescopic rod is fixedly connected to the top surface of the transmission gear, and the hopper stirring shaft is connected to the transmission gear through the first wheel, the transmission belt, the second wheel, and the second electric telescopic rod.

[0015] The present invention provides a raw material proportioning device for glass processing, which has the following beneficial effects:

[0016] 1. This glass processing raw material proportioning device utilizes the sector-shaped teeth on the outer surface of the sector gear to intermittently drive the transmission gear during rotation, thereby driving the screw feed shaft in the screw conveyor to intermittently rotate. This conveys raw materials within each storage hopper. During each conveying pause, the weighing plate performs a delayed weighing to determine the total amount of remaining raw materials, thereby obtaining highly accurate data on the amount of raw materials injected. Combined with the variable speed function of the variable speed motor, the raw material conveying phase is divided into a rapid feeding stage and a precise filling stage, thereby improving raw material conveying efficiency, preventing overfeeding, and increasing the accuracy of raw material injection into the mixing barrel.

[0017] 2. This glass processing raw material proportioning device uses an output shaft to drive the synchronous rotation of inclined blades. Simultaneously, the outer ends of the inclined blades vibrate as they rotate through the movable balls inside the guide rails. This vibration causes the raw materials located in the inner gaps between the inclined blades to move outward, causing them to fall through the large gaps. This allows the raw materials to fall evenly to various locations at the bottom of the mixing barrel, achieving pre-mixing of the raw materials. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] The following embodiments of the present invention are described in further detail with reference to the accompanying drawings and examples. The following examples are used to illustrate the present invention but are not intended to limit the scope of the present invention.

[0026] like Figures 1-6As shown, the present invention provides a technical solution: a raw material proportioning device for glass processing, comprising a mixing barrel 1 and a proportioning assembly 3, a support frame 2 is fixed on the top of the mixing barrel 1, the proportioning assembly 3 comprises a variable speed motor 301 fixed to the top of the support frame 2, and the bottom of the variable speed motor 301 is connected to an output shaft 302, a sector gear 303 is fixed to the upper part of the outer wall of the output shaft 302, and the outer side surface of the sector gear 303 is meshedly connected to a transmission gear 304, and the bottom of the transmission gear 304 is connected to a first electric telescopic rod 305, and The bottom of the first electric telescopic rod 305 is connected to a gear steering box 306 via a damping shaft. The outer side of the gear steering box 306 is connected to a screw conveyor 307, and the end of the screw conveyor 307 away from the gear steering box 306 is connected to a storage hopper 308. A weighing plate 309 is connected to the bottom of the screw conveyor 307, the gear steering box 306, and the storage hopper 308. A discharge pipe 310 is provided at the bottom of the end of the screw conveyor 307 close to the gear steering box 306, and an electronic valve is provided at the bottom of the discharge pipe 310.

[0027] The specific operation is as follows: the weighing plate 309 has a weighing function and monitors the total weight of the raw materials in the storage hopper 308, the screw conveyor 307, and the discharge pipe 310 in real time. When the glass raw materials are proportioned, each raw material is fed into each storage hopper 308 until the weight measured by the weighing plate 309 reaches the preset weight. Then, the variable speed motor 301 drives the output shaft 302 to rotate the sector gear 303. During the rotation of the sector gear 303, the sector-shaped tooth grooves on its outer surface intermittently drive the transmission gear 304 to rotate. The transmission gear 304 is then turned by the bevel gear set inside the gear steering box 306 to drive the screw feed shaft in the screw conveyor 307 to intermittently rotate.

[0028] When the spiral feed shaft in the screw conveyor 307 rotates intermittently, the raw materials in the storage hopper 308 are sent out from the discharge pipe 310 and enter the mixing barrel 1. When the transmission gear 304 and the sector gear 303 are temporarily separated, the speed sensor in the gear steering box 306 detects that the speed is zero. At this time, the electronic valve at the bottom of the discharge pipe 310 is closed, and the weighing plate 309 delays the detection of the remaining weight of the raw materials in the storage hopper 308, the screw conveyor 307, and the discharge pipe 310 in a stagnant state. Since the weight of the raw materials is detected in a static state, the interference of the movement of the raw materials on the detection accuracy can be avoided. The delayed weighing of the weighing plate 309 can avoid the movement of the raw materials due to inertia in the stagnant state, which may cause inaccurate detection. The longest delay time is before the next rotation of the transmission gear 304.

[0029] The conveying of each raw material is divided into a fast feeding stage and a precise feeding stage. In the fast feeding stage, the screw conveyor shaft in the screw conveyor 307 conveys the raw material to 90% of the preset amount at a high speed, such as 80 rpm, to shorten the batching time. In the precise feeding stage, when conveying the remaining 10% of the raw material, the screw conveyor shaft switches to a low speed, such as 20 rpm or even lower, to slowly convey the raw material until the remaining weight reaches the target value. The raw material moves slowly to reduce the detection interference of the weighing plate 309 and reduce the over-feeding caused by inertial impact, thereby achieving precise control of the raw material conveying and making the raw materials accurately proportioned during mixing.

[0030] Finally, after the raw material delivery and injection reaches a preset amount, the first electric telescopic rod 305 contracts so that the transmission gear 304 is actively separated from the sector gear 303, so that the corresponding screw conveyor 307 no longer conveys raw materials;

[0031] Based on the above description, the present invention utilizes the fan-shaped tooth grooves on the outer side of the fan-shaped gear 303 during its rotation to intermittently drive the transmission gear 304 to rotate, thereby driving the screw feed shaft in the screw conveyor 307 to intermittently rotate, thereby transporting the raw materials inside each storage hopper 308. At each conveying stagnation, the weighing plate 309 delays weighing to obtain the total amount of remaining raw materials, thereby obtaining high-precision data on the amount of raw materials injected, and cooperates with the speed change function of the speed change motor 301 to divide the raw material transportation into a fast feeding stage and a precise feeding stage, so as to improve the raw material transportation efficiency, prevent excessive transportation, and at the same time improve the accuracy of the raw material injection into the mixing barrel 1.

[0032] like Figures 1-6 As shown, the proportioning component 3 also includes a T-shaped bracket 311 and a hopper stirring shaft 312. The T-shaped bracket 311 is fixed to the top side of the storage hopper 308, and the top of the T-shaped bracket 311 is rotatably connected to the hopper stirring shaft 312 at one end near the middle of the storage hopper 308. The proportioning component 3 also includes a first wheel disc 313. The top of the hopper stirring shaft 312 is fixed with the first wheel disc 313. The proportioning component 3 also includes a second wheel disc 314. The end of the T-shaped bracket 311 away from the hopper stirring shaft 312 is rotatably connected to the second wheel disc 314. The proportioning assembly 3 also includes a transmission belt 315. The second wheel disc 314 and the outer wall of the first wheel disc 313 are sleeved with and meshed with the transmission belt 315. The proportioning assembly 3 also includes a second electric telescopic rod 316. The second electric telescopic rod 316 is inserted into the bottom of the second wheel disc 314. The bottom of the second electric telescopic rod 316 is fixedly connected to the top surface of the transmission gear 304. The hopper stirring shaft 312 is transmission-connected to the transmission gear 304 through the first wheel disc 313, the transmission belt 315, the second wheel disc 314, and the second electric telescopic rod 316.

[0033] The specific operation is as follows: in the fast feeding stage, when the transmission gear 304 rotates, it also drives the second wheel disc 314 to rotate through the second electric telescopic rod 316, and the second wheel disc 314 drives the first wheel disc 313 through the transmission belt 315, so that the hopper stirring shaft 312 rotates inside the storage hopper 308. The rotation of the hopper stirring shaft 312 loosens the raw materials inside the storage hopper 308 so that they can pass through the bottom outlet of the storage hopper 308 and enter the screw conveyor 307. In the stagnant state, the hopper stirring shaft 312 and the screw feeding shaft are stationary together, so that the weighing plate 309 can weigh accurately.

[0034] During the precise feeding stage, the second electric telescopic rod 316 contracts and separates from the second wheel 314. At this time, the hopper stirring shaft 312 is in a stationary state inside the storage hopper 308 to prevent the weighing plate 309 from weighing the material while it is slowly moving, thereby affecting the weighing accuracy due to the rotation of the hopper stirring shaft 312.

[0035] like Figures 1-6 As shown, a guide rail 4 is fixed to the upper part of the inner wall of the mixing barrel 1, and a movable ball 5 is embedded in the top of the inner wall of the guide rail 4 in a ring shape. A stirring blade 6 is fixed to the outer wall of the bottom of the output shaft 302, and a shaking assembly 7 is fixed to the outer wall of the output shaft 302 between the stirring blade 6 and the sector gear 303. The shaking assembly 7 includes a fixed ring sleeve 701 and inclined blades 702. The inclined blades 702 are evenly distributed on the outer side of the fixed ring sleeve 701, and the end of the inclined blade 702 away from the fixed ring sleeve 701 is located inside the guide rail 4;

[0036] The specific operation is as follows: the gaps between the inclined blades 702 gradually become larger from the inside to the outside, and the raw materials conveyed by the screw conveyor 307 fall along the discharge pipe 310 to the end between the inclined blades 702 and at the narrower gap. As the raw materials roll along the gaps between the inclined blades 702, and the inclined blades 702 rotate synchronously with the output shaft 302, the raw materials fall downward from different gaps to the bottom of the mixing barrel 1. As the inclined blades 702 rotate, their outer ends constantly contact and separate with the movable balls 5 inside the guide rails 4, thereby causing the inclined blades 702 to vibrate during rotation, so that the raw materials roll along the gaps toward the outer ends under the shaking action and fall smoothly, preventing the raw materials from getting stuck in the gaps.

[0037] Then the output shaft 302 drives the mixing blade 6 to rotate to mix the raw materials;

[0038] Based on the above description, the present application utilizes the output shaft 302 to drive the inclined blades 702 to rotate synchronously, and the outer ends of the inclined blades 702 vibrate due to the rotation of the movable ball 5 inside the guide rail 4, so that the raw materials between the inclined blades 702 at the inner side gap move outward under the vibration, and then fall from the large gap, so that the raw materials can be uniformly dropped to each part of the mixing barrel 1 bottom to realize the premixing of the raw materials.

[0039] In summary, the glass processing raw material proportioning device, in use, first, when the glass raw material is proportioned, each raw material is sent to each storage hopper 308 until the weight measured by the weighing plate 309 reaches the preset weight, and then the variable speed motor 301 drives the output shaft 302 to make the sector gear 303 rotate, and the sector gear 303 rotates intermittently to drive the transmission gear 304 to rotate through the sector gear groove on the outer side of the sector gear 303, and the transmission gear 304 is thus diverted by the bevel gear set inside the gear steering box 306 to drive the screw conveying shaft in the screw conveyor 307 to rotate intermittently;

[0040] When the screw conveying shaft in the screw conveyor 307 rotates intermittently, the raw materials inside the storage hopper 308 are sent out from the discharge pipe 310 and into the mixing barrel 1, and when the transmission gear 304 and the sector gear 303 are temporarily separated, the rotation speed sensor inside the gear steering box 306 detects that the rotation speed is zero, at which time the electronic valve at the bottom of the discharge pipe 310 is closed, and the weighing plate 309 detects the remaining weight of the raw materials inside the storage hopper 308, the screw conveyor 307 and the discharge pipe 310 in a static state, which can avoid the interference of the movement of the raw materials on the detection accuracy, and the delayed weighing of the weighing plate 309 can avoid the movement of the raw materials due to inertia in the just static state, which can cause detection error, and the longest delay time is before the next rotation of the transmission gear 304;

[0041] The transportation of each raw material is divided into a fast feeding stage and a precise feeding stage, in the fast feeding stage, the screw conveying shaft in the screw conveyor 307 transports the raw materials to 90% of the preset amount at a high speed such as 80 rpm, to shorten the batching time, and in the precise feeding stage, the screw conveying shaft is switched to a low speed such as 20 rpm or even lower to slowly transport the remaining 10% of the raw materials to the target value, and the slow movement of the raw materials reduces the detection interference of the weighing plate 309, and reduces the excessive transportation caused by inertia impact, so as to realize the precise control of the raw material transportation, and make the proportioning of each raw material accurate during mixing;

[0042] After the raw material delivery and injection reaches a preset amount, the control chip receives a signal indicating that the delivery amount has reached the standard. At this time, the control chip sends a control signal to cause the first electric telescopic rod 305 to retract, so that the transmission gear 304 actively separates from the sector gear 303, so that the corresponding screw conveyor 307 no longer conveys raw materials;

[0043] In the fast feeding stage, when the transmission gear 304 rotates, it also drives the second wheel disc 314 to rotate through the second electric telescopic rod 316. The second wheel disc 314 drives the first wheel disc 313 through the transmission belt 315, so that the hopper stirring shaft 312 rotates inside the storage hopper 308. The rotation of the hopper stirring shaft 312 loosens the raw materials inside the storage hopper 308 so that they can pass through the bottom outlet of the storage hopper 308 and enter the screw conveyor 307. In the stagnant state, the hopper stirring shaft 312 and the screw feeding shaft are stationary together, so that the weighing plate 309 can weigh the raw materials accurately.

[0044] During the precise feeding stage, the second electric telescopic rod 316 is retracted and separated from the second wheel 314. At this time, the hopper stirring shaft 312 is in a stationary state inside the storage hopper 308 to prevent the weighing plate 309 from weighing the material while it is slowly moving, which may affect the weighing accuracy.

[0045] The raw materials transported by the screw conveyor 307 fall along the discharge pipe 310 between the inclined blades 702 and are located at one end of the finer gap. As the raw materials roll along the gaps between the inclined blades 702, and the inclined blades 702 rotate synchronously with the output shaft 302, the raw materials fall downward from different gaps to the bottom of the mixing barrel 1. When the inclined blades 702 rotate, their outer ends continuously contact and separate with the movable balls 5 inside the guide rails 4, thereby causing the inclined blades 702 to vibrate during rotation, so that the raw materials roll along the gaps to the outer ends under the shaking action and fall smoothly, avoiding the raw materials from being stuck in the gaps. Then, the mixing blades 6 are driven to rotate through the output shaft 302 to mix the raw materials.

[0046] The embodiments of the present invention are presented for purposes of illustration and description and are not intended to be exhaustive or to limit the invention to the disclosed forms. Many modifications and variations will be apparent to those skilled in the art. The embodiments are chosen and described in order to better illustrate the principles of the invention and its practical application and to enable those skilled in the art to understand the invention and design various embodiments with various modifications as suited for specific applications.
