Description

Technical Field

[0001] The present invention relates to the technical field of glass processing, and particularly 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 substances with good fluidity. When proportioning the raw materials, it is necessary to weigh them so that each raw material can be mixed according to a certain proportion, thereby producing high-quality glass.

[0003] There are mainly two existing methods for proportioning glass raw materials. One is to use a weighing hopper to weigh the raw materials after reaching the preset weight, and then pour the raw materials in the hopper into the mixing barrel at one time. The other method is to directly inject more raw materials than the preset amount into the weighing hopper. As the hopper continuously feeds the raw materials 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, in the above two methods, in the former method, when injecting more raw materials than the preset amount into the weighing hopper, it is necessary to take out the excess raw materials, and in the latter method, since the raw materials are continuously moving, it is easy to interfere with the detection of the sensor, thereby affecting the accuracy, resulting in an error from the actual injection amount of the raw materials. Summary of the Invention

[0004] In view of the deficiencies of the prior art, the present invention provides a raw material proportioning device for glass processing, which solves the problems raised in the above background art.

[0005] To achieve the above object, the present invention is realized through the following technical solutions: A raw material proportioning device for glass processing, including a mixing barrel and a proportioning component. A support frame is fixed at the top of the mixing barrel. The proportioning component includes a variable-speed motor fixed at the top of the support frame, and an output shaft is connected to the bottom of the variable-speed motor. An upper part of the outer wall of the output shaft is fixed with a sector gear, and a transmission gear is meshed and connected to the outer side of the sector gear. A first electric telescopic rod is connected to the bottom of the transmission gear, and the bottom of the first electric telescopic rod is connected to a gear steering box through a damping rotating shaft. A screw conveyor is connected to the outer side of the gear steering box, and one end of the screw conveyor far from the gear steering box is connected to a storage hopper. A weighing plate is connected to the bottoms of the screw conveyor, the gear steering box, and the storage hopper. A discharge pipe is arranged at the bottom of the screw conveyor near the gear steering box, and an electronic valve is arranged at the bottom of the discharge pipe.

[0006] Furthermore, the proportioning component further includes a T-shaped bracket and a hopper stirring shaft. A T-shaped bracket is fixed at the top edge side of the storage hopper, and one end of the T-shaped bracket near the middle of the storage hopper at the top is rotatably connected to the hopper stirring shaft.

[0007] Furthermore, the proportioning component further includes a first round plate, and the first round plate is fixed at the top of the hopper stirring shaft.

[0008] Further, the proportioning component further includes a second disc, and one end of the T-shaped bracket away from the hopper stirring shaft is rotatably connected to the second disc.

[0009] Further, the proportioning component further includes a transmission belt, and the outer walls of the second disc and the first disc are sleeved and meshed with the transmission belt.

[0010] Further, the proportioning component further includes a second electric telescopic rod, and the second electric telescopic rod is inserted into the bottom of the second disc.

[0011] Further, 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 in transmission connection with the transmission gear through the first disc, the transmission belt, the second disc, and the second electric telescopic rod.

[0012] Further, a guide rail is fixedly installed on the upper part of the inner wall of the mixing barrel, and movable balls are annularly embedded at the top of the inner wall of the guide rail.

[0013] Further, stirring blades are fixedly installed on the outer wall of the bottom of the output shaft, and a material shaking component is fixedly installed on the outer wall of the output shaft between the stirring blades and the sector gear.

[0014] Further, the material shaking component includes a fixed ring sleeve and inclined blades. The inclined blades are evenly distributed on the outer side of the fixed ring sleeve, and one end of the inclined blade away from the fixed ring sleeve is located inside the guide rail.

[0015] The present invention provides a raw material proportioning device for glass processing, which has the following beneficial effects: 1. For the raw material proportioning device for glass processing, the sector-shaped tooth grooves on the outer side surface during the rotation of the sector gear are used to intermittently drive the rotation of the transmission gear, thereby driving the intermittent rotation of the screw feeding shaft in the screw conveyor, so as to convey the raw materials in each storage hopper. When the conveying stops each time, the weighing plate weighs with a time delay to obtain the total amount of the remaining raw materials, so as to obtain high-precision data of the injected raw material amount, and cooperate with the variable-speed function of the variable-speed motor to divide the raw material conveying into a rapid feeding stage and a precise supplementary feeding stage, so as to improve the raw material conveying efficiency, prevent over-conveying, and at the same time improve the accuracy of injecting the raw material amount into the mixing barrel.

[0016] 2. For the raw material proportioning device for glass processing, the output shaft drives the inclined blades to rotate synchronously. At the same time, the outer end of the inclined blade trembles due to the rotation through the movable balls inside the guide rail, so that the raw materials located at the inner gap between the inclined blades can move outward under the shaking action and fall from the large gap, so that the raw materials can evenly fall to each part at the bottom of the mixing barrel to realize the pre-mixing between the raw materials.

Detailed implementation manners

[0019] The following further describes in detail the implementation manners of the present invention in conjunction with the drawings and embodiments. The following embodiments are used to illustrate the present invention, but cannot be used to limit the scope of the present invention.

[0020] As Figures 1-6As shown in the figure, the present invention provides a technical solution: a raw material proportioning device for glass processing, including a mixing barrel 1 and a proportioning component 3. A support frame 2 is fixed on the top of the mixing barrel 1. The proportioning component 3 includes a variable-speed motor 301 fixed on the top of the support frame 2. The bottom of the variable-speed motor 301 is connected with an output shaft 302. An upper part of the outer wall of the output shaft 302 is fixed with a sector gear 303. The outer side of the sector gear 303 is meshed and connected with a transmission gear 304. The bottom of the transmission gear 304 is connected with a first electric telescopic rod 305. The bottom of the first electric telescopic rod 305 is connected with a gear steering box 306 through a damping rotating shaft. The outer side of the gear steering box 306 is connected with a screw conveyor 307. One end of the screw conveyor 307 far from the gear steering box 306 is connected with a storage hopper 308. The bottoms of the screw conveyor 307, the gear steering box 306, and the storage hopper 308 are connected with a weighing plate 309. A discharge pipe 310 is arranged at the bottom of one end of the screw conveyor 307 close to the gear steering box 306. An electronic valve is arranged at the bottom of the discharge pipe 310; The specific operation is as follows. The weighing plate 309 has a weighing function and actually monitors the total weight of the raw materials inside the storage hopper 308, the screw conveyor 307, and the discharge pipe 310. When proportioning glass raw materials, each raw material is sent 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 make the sector gear 303 rotate. During the rotation of the sector gear 303, the sector tooth grooves on its outer side intermittently drive the transmission gear 304 to rotate. The transmission gear 304 is thus steered through the bevel gear set inside the gear steering box 306 to drive the screw feeding shaft in the screw conveyor 307 to rotate intermittently; When the screw feeding 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 enter the mixing barrel 1. When the transmission gear 304 is temporarily separated from the sector gear 303, the rotational speed sensor inside the gear steering box 306 detects that the rotational speed is zero. At this 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 time-delayed manner in the stagnant state. Since the weight of the raw materials is detected in the static state, the interference of the movement of the raw materials on the detection accuracy can be avoided. The time-delayed weighing of the weighing plate 309 can avoid the detection inaccuracy caused by the movement of the raw materials due to inertia in the just-stagnant state. The longest time delay is before the next rotation of the transmission gear 304; The conveying of each raw material is divided into a rapid feeding stage and a precise feeding stage. During the rapid feeding stage, the spiral feeding shaft in the spiral conveyor 307 rotates at a high speed, such as 80 rpm, to convey the raw material to 90% of the preset amount, so as to shorten the batching time. During the precise feeding stage, when conveying the remaining 10% of the raw material, the spiral feeding 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 with the weighing plate 309 and reduce the excessive conveying caused by inertial impact, so as to realize the precise control of the raw material conveying and make the ratio of each raw material accurate during mixing; Finally, after the raw material conveying and injection reach the preset amount, the first electric telescopic rod 305 contracts, so that the driving gear 304 is disengaged from the sector gear 303 actively, and the corresponding spiral conveyor 307 stops conveying the raw material; Based on the above description, the present invention uses the sector tooth grooves on the outer side of the sector gear 303 during rotation to intermittently drive the driving gear 304 to rotate, thereby driving the spiral feeding shaft in the spiral conveyor 307 to rotate intermittently, so as to convey the raw materials in each storage hopper 308. When the conveying stops each time, the weighing plate 309 weighs with a time delay to obtain the total amount of the remaining raw materials, so as to obtain high-precision data of the injected raw material amount, and cooperate with the variable speed function of the variable speed motor 301 to divide the raw material conveying into a rapid feeding stage and a precise feeding stage, so as to improve the raw material conveying efficiency, prevent excessive conveying, and improve the accuracy of injecting the raw material amount into the mixing barrel 1.

[0021] As Figures 1-6 shown, the proportioning assembly 3 further includes a T-shaped bracket 311 and a hopper stirring shaft 312. A T-shaped bracket 311 is fixed at the top side of the storage hopper 308, and a hopper stirring shaft 312 is rotatably connected to one end of the T-shaped bracket 311 close to the middle of the storage hopper 308. The proportioning assembly 3 further includes a first disc 313, and a first disc 313 is fixed to the top of the hopper stirring shaft 312. The proportioning assembly 3 further includes a second disc 314, and a second disc 314 is rotatably connected to one end of the T-shaped bracket 311 away from the hopper stirring shaft 312. The proportioning assembly 3 further includes a transmission belt 315, and the outer walls of the second disc 314 and the first disc 313 are sleeved and meshed with the transmission belt 315. The proportioning assembly 3 further includes a second electric telescopic rod 316, and the second electric telescopic rod 316 is inserted into the bottom of the second disc 314. The bottom of the second electric telescopic rod 316 is fixedly connected to the top surface of the driving gear 304, and the hopper stirring shaft 312 is in transmission connection with the driving gear 304 through the first disc 313, the transmission belt 315, the second disc 314 and the second electric telescopic rod 316; The specific operations are as follows. During the rapid feeding stage, when the transmission gear 304 rotates, it will drive the second turntable 314 to rotate through the second electric telescopic rod 316. The second turntable 314 drives the first turntable 313 through the transmission belt 315, causing the hopper stirring shaft 312 to rotate 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 enter the screw conveyor 307 through the bottom outlet of the storage hopper 308. When in a stagnant state, the hopper stirring shaft 312 and the screw feeding shaft are stationary together, thus facilitating the accurate weighing of the weighing plate 309; During the precise feeding stage, the second electric telescopic rod 316 contracts and separates from the second turntable 314. At this time, the hopper stirring shaft 312 is in a static state inside the storage hopper 308 to prevent the weighing accuracy of the weighing plate 309 from being affected by the rotation of the hopper stirring shaft 312 when weighing under the condition of slow movement of the materials.

[0022] As Figures 1-6 shown in the figure, a guide rail 4 is fixed to the upper part of the inner wall of the mixing barrel 1, and movable balls 5 are annularly embedded in the top of the inner wall of the guide rail 4. A stirring blade 6 is fixed to the bottom outer wall of the output shaft 302, and a material shaking assembly 7 is fixed between the stirring blade 6 and the sector gear 303 on the outer wall of the output shaft 302. The material 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 far from the fixed ring sleeve 701 is located inside the guide rail 4; The specific operations are as follows. The gap between the inclined blades 702 gradually increases from the inside to the outside. The raw materials conveyed by the screw conveyor 307 fall along the discharge pipe 310 between the inclined blades 702 and are located at the end with a thinner gap. As the raw materials roll along the gap 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 from the movable balls 5 inside the guide rail 4. As a result, the inclined blades 702 tremble during rotation, causing the raw materials to roll outward along the gap under the shaking effect and fall smoothly, preventing the raw materials from getting stuck in the gap; Then, the output shaft 302 drives the stirring blade 6 to rotate to mix the various raw materials; Based on the above description, the present invention utilizes the output shaft 302 to drive the inclined blades 702 to rotate synchronously. At the same time, the outer ends of the inclined blades 702 tremble due to rotation through the movable balls 5 inside the guide rail 4, causing the raw materials located at the inner side gap between the inclined blades 702 to move outward under the shaking effect and fall from the larger gap, enabling the raw materials to evenly fall to various parts of the bottom of the mixing barrel 1 to achieve pre-mixing between the raw materials.

[0023] In summary, when the raw material proportioning device for glass processing is in use, first, when proportioning glass raw materials, each raw material is sent 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 make the sector gear 303 rotate. During the rotation of the sector gear 303, the sector tooth grooves on its outer side intermittently drive the transmission gear 304 to rotate. The transmission gear 304 is thus steered by the bevel gear set inside the gear steering box 306 to drive the spiral feeding shaft in the screw conveyor 307 to rotate intermittently; When the spiral feeding 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 enter the mixing barrel 1. When the transmission gear 304 is temporarily separated from the sector gear 303, the rotational speed sensor inside the gear steering box 306 detects that the rotational speed is zero. At this time, the solenoid valve at the bottom of the discharge pipe 310 closes, 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 time-delayed manner. Since the weight of the raw materials is detected in a stationary state, the interference of raw material movement on the detection accuracy can be avoided. The time-delayed weighing of the weighing plate 309 can avoid the detection inaccuracy caused by the movement of the raw materials due to inertia in the just-stopped state, and the longest time delay is before the next rotation of the transmission gear 304; The feeding of each raw material is divided into a rapid feeding stage and a precise feeding stage. During the rapid feeding stage, the spiral feeding shaft in the screw conveyor 307 rotates at a high speed, such as 80 rpm, to convey the raw materials to 90% of the preset amount, so as to shorten the batching time. During the precise feeding stage, when conveying the remaining 10% of the raw materials, the spiral feeding shaft switches to a low speed, such as 20 rpm or even lower, to slowly convey the raw materials until the remaining weight reaches the target value. The raw materials move slowly to reduce the detection interference on the weighing plate 309 and reduce the over-conveying caused by inertial impact, so as to realize the precise control of the raw material conveying and make the proportioning of each raw material accurate during mixing; After the raw material conveying and injection reach the preset amount, the control chip receives the signal that the conveying amount reaches the standard. At this time, the control chip sends a control signal to make the first electric telescopic rod 305 contract, so that the transmission gear 304 is actively separated from the sector gear 303, and the corresponding screw conveyor 307 stops conveying raw materials; Among them, during the rapid feeding stage, when the transmission gear 304 rotates, it will also drive the second turntable 314 to rotate through the second electric telescopic rod 316. The second turntable 314 drives the first turntable 313 through the transmission belt 315, causing the hopper stirring shaft 312 to rotate 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 enter the screw conveyor 307 through the bottom outlet of the storage hopper 308. During the stagnant state, the hopper stirring shaft 312 and the screw feeding shaft are stationary together, thus facilitating the accurate weighing of the weighing plate 309; During the accurate feeding stage, the second electric telescopic rod 316 contracts and separates from the second turntable 314. At this time, the hopper stirring shaft 312 is in a static state inside the storage hopper 308 to avoid affecting the weighing accuracy of the weighing plate 309 due to the rotation of the hopper stirring shaft 312 when weighing under the slow movement of the materials; The raw materials conveyed by the screw conveyor 307 fall between the inclined blades 702 and at one end of the relatively narrow gap along the discharge pipe 310. As the raw materials roll along the gap 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 from the movable balls 5 inside the guide rail 4. Thus, the inclined blades 702 tremble during rotation, causing the raw materials to roll outward along the gap under the shaking effect and fall smoothly, preventing the raw materials from getting stuck in the gap. Then, the stirring blades 6 are driven by the output shaft 302 to mix the raw materials.
