A raw material quantitative conveyor for glass industry production

Abstract

The invention discloses a raw material quantitative conveyor for glass industry production, and the invention relates to the technical field of conveyors. During quantitative conveying, the raw material particles in the quantitative cylinder are not adjusted by vibration during conveying, so that the raw material particles in the quantitative container cannot ensure that the space is completely filled, resulting in reduced quantitative accuracy of the quantitative container. Therefore, through the cooperation of a spring plate and a hammer, when the hammer contacts the spring plate during the rotation of the quantitative cylinder, the spring plate is pressed to deform and compress, so that the spring plate has a rebound force, and the hammer is hammered toward the outside of the quantitative cylinder with a higher frequency and a greater force, so that the quantitative cylinder vibrates. During the vibration of the quantitative cylinder, the gaps between the raw materials in the quantitative cylinder are reduced, so that the quantitative quantity of the quantitative cylinder is more standard, and at the same time, the top layer of the raw materials surging up is kept flat, so as to improve the quantitative accuracy during output.

[0002] At present, the main raw material of glass is quartz sand. Small particles of quartz sand are usually heated during production. Conveyor is a material handling machine that continuously transports materials on a certain route, also known as continuous conveyor. It can be transported horizontally, inclined and vertically, and can also form a spatial conveying line. The conveying line is generally fixed.

[0009] Preferably, a perforated plate is evenly installed on the outer side of the sleeve, and a connecting rod is fixedly connected to the inner wall of the perforated plate, and a scraper is fixedly connected to the bottom end of the connecting rod. The scraping of the scraper cooperates with the knocking of the hammer to make the surface of the gushing raw material always flush with the cylinder body of the metering cylinder, so as to maintain the accuracy of the metering, so that the raw material falls quantitatively into the material guide groove for quantitative output, and the bottom end of the scraper fits with the top end of the metering cylinder, and the opposite surface of the scraper is an arc surface, and the opposite surface of the scraper fits with the outer side of the connecting shaft, the feeding cylinder is located at the center of the bottom of the metering cylinder, and the feeding cylinder will twist the The dragon shaft cover is inside, and the inner wall of the stacking bin is fixedly connected with a material guide plate, and the top flange of the connecting shaft is connected with a baffle cover, which is used to block the top of the metering cylinder to prevent the particles from being bounced out during transportation when the raw materials are surging.

[0012] The present invention provides a raw material quantitative conveyor for glass industry production, which has the following beneficial effects:

[0013] 1. The raw material quantitative conveyor produced by the glass industry cooperates with the spring plate and the hammer. When the hammer contacts the spring plate during the rotation of the quantitative cylinder, the spring plate is compressed and deformed, so that the spring plate has a rebound force.

[0014] 2. The raw material quantitative conveyor produced by the glass industry, through the scraping of the scraper and the knocking of the hammer, makes the surface of the gushing raw material always flush with the cylinder body of the quantitative cylinder, maintains the accuracy of the material dosage, and makes the raw material fall into the material guide trough in a quantitative manner for quantitative output.

[0015] 3. The quantitative conveyor for raw materials produced by the glass industry uses a baffle to block the top of the quantitative cylinder to prevent particles from being bounced out during transportation when the raw materials are surging. If there is no blockage, the raw materials will splash out of the conveyor, resulting in inaccurate quantitative transportation, and at the same time avoiding injuries to personnel caused by splashing raw materials.

[0016] 4. The raw material quantitative conveyor produced by the glass industry wraps the raw materials during the loading process through a dustproof plate to prevent dust from splashing everywhere during the transportation process. At the same time, the clamped spreading plate can keep the raw materials at the same thickness on the surface of the conveyor belt, so that they can maintain the same drop position when conveyed out, and can be better transported to the stacking bin.

[0017] 5. The quantitative conveyor for raw materials produced by the glass industry can guide the raw materials smoothly to the conveyor belt by rotating the rotating plate. At the same time, the rotating rotating plate can be pressed against the conveyor belt according to the texture and protrusions on the surface of the conveyor belt under the pressure of the top raw materials, so as to prevent the raw materials from falling during the conveyor belt transportation and causing the raw materials to leak in the conveyor.

At the same time, the stepper motor 6 drives the auger shaft 205 to rotate, so that the raw materials concentrated in the center position are rotated by the auger shaft 205 to enter the feed cylinder 206, and the raw materials are transported by the feed cylinder 206 and the auger shaft 205 to enter the quantitative cylinder 207, so that the raw materials in the quantitative cylinder 207 continue to surge upward until they surge out of the quantitative cylinder 207, so that the quantitative cylinder 207 cooperates with the unloading component 210 to make the raw materials quantitatively fall into the guide groove 204, and the raw materials are discharged along the guide groove 204 and enter the processing equipment.

The rollers 32 are symmetrically installed along the center position of the axis of the inner baffles 34, and the feeding motor 5 drives the rollers 32 to rotate, so that the rollers 32 drive the conveyor belt 33 to run, so that the raw materials transmitted to the surface of the conveyor belt 33 are driven. In the process of driving, the raw materials are blocked on both sides of the conveyor belt 33 when the conveyor belt 33 drives the raw materials to move.

[0036] The third embodiment is based on the first and second embodiments. Figure 8 As shown, the screening mechanism 4 includes a feed bin 41, the side of the feed bin 41 close to the feeding mechanism 3 is fixedly connected to the outer side of the frame 1, and an inclined screen plate 42 is fixedly installed on the top of the inner wall of the feed bin 41, and the inclined screen plate 42 is inclined downward away from the feeding mechanism 3. A guide plate 43 is fixedly installed on the bottom of the inner wall of the feed bin 41. Workers pour raw materials into the feed bin 41. After the raw materials enter the feed bin 41, the raw materials first contact the inclined screen plate 42, so that the raw materials slide down along the inclined angle of the inclined screen plate 42. In the process of sliding down, the raw materials are The raw materials pass through the inclined screen plate 42, so that large impurities are blocked by the inclined screen plate 42. At the same time, the raw materials fall on the surface of the guide plate 43 after passing through the inclined screen plate 42. The guide plate 43 is inclined upward on the side away from the feeding mechanism 3, and a rotating plate 44 is rotatably installed on the end of the guide plate 43 close to the conveyor belt 33. The end of the rotating plate 44 close to the conveyor belt 33 is fitted with the outer side of the conveyor belt 33 and slides along the inclined angle of the guide plate 43 towards the feeding mechanism 3. At the same time, the raw materials are guided by the rotating plate 44 to be conducted to the feeding mechanism 3 through the rotating plate 44.

[0037] When in use, workers pour the quartz sand raw materials for glass production into the screening mechanism 4, screen the raw materials through the screening mechanism 4, start the feeding motor 5 and the stepper motor 6, and drive the feeding mechanism 3 to run through the feeding motor 5, and drive the raw materials screened by the screening mechanism 4 to be transported to the quantitative mechanism 2. After the raw materials enter the quantitative mechanism 2, they are driven by the stepper motor 6 to output quantitatively, so that the raw materials are quantitatively input into the processing equipment.

[0038] When the raw materials enter the screening mechanism 4, the workers pour the raw materials into the feed bin 41. After entering the feed bin 41, the raw materials first contact the inclined screen plate 42, so that the raw materials slide along the inclined angle of the inclined screen plate 42, and pass through the inclined screen plate 42 in the process of sliding, so that large impurities are blocked by the inclined screen plate 42. At the same time, the raw materials fall on the surface of the guide plate 43 after passing through the inclined screen plate 42, and slide along the inclined angle of the guide plate 43 toward the upper feeding mechanism 3. At the same time, the raw materials are guided by the rotating plate 44 to be conducted to the upper feeding mechanism 3 through the rotating plate 44.

[0039] In the feeding mechanism 3, the feeding motor 5 drives the roller 32 to rotate, so that the roller 32 drives the conveyor belt 33 to run, and the raw materials transmitted to the surface of the conveyor belt 33 are driven. In the process of driving, the inner baffle plate 34 blocks the raw materials on both sides of the conveyor belt 33 while the conveyor belt 33 drives the raw materials to move. At the same time, in the process of conveying, the spreading plate 36 connected by the dustproof plate 35 is used to spread the raw materials during the conveying process.

[0040] After being transported by the conveyor belt 33, the raw materials fall into the stacking bin 201, and are guided to the bottom center by the internal guide plate 203.

In the process of the rotation of the connecting rod 2109, the scraper 2108 is driven to rotate along the top of the quantitative cylinder 207 to scrape the raw material flowing out of the quantitative cylinder 207, so that the raw material falls. At the same time, when scraping the gushing raw material, the rotating The arm 2103 drives the rotating column 2104 to move, and the centrifugal force of the hammer 2106 at the bottom of the rotating column 2104 during the rotation process causes the rotating column 2104 to rotate, and the hammer 2106 moves outward and contacts the ring 2107, so that when the spring plate 2105 inside the ring 2107 contacts the rotating hammer 2106, the spring plate 2105 rebounds through the deformation, and the hammer 2106 is rebounded toward the metering cylinder 207. At this time, the hammer 2106 hits the metering cylinder 207, and the raw material particles inside the metering cylinder 207 fit tightly together.
