Description

Technical Field

[0001] The invention relates to the technical field of feeding devices, in particular to an automatic feeding device for gypsum mortar. Background Art

[0002] Gypsum is a monoclinic mineral and a hydrate whose main chemical component is calcium sulfate. Gypsum is a widely used industrial material and building material. It can be used as a cement retarder, gypsum building products, model making, medical food additive, sulfuric acid production, paper filler, paint filler, etc.

[0003] In the process of producing gypsum mortar, a conveying device is needed, and a spiral auger is needed to transport the gypsum raw materials to the inside of the mixing device. This is because most mixing devices are several meters above the ground. Therefore, in order to reduce the trouble of manual transportation, an auger is used for transportation operations.

[0004] However, the following situations may occur when using the auger. For example, during use, since the length of the auger is fixed during the production process, once the height encountered is higher than the auger, the auger cannot operate. Moreover, the auger plus the loading box currently on the market occupies a wider area, and the longer the auger, the longer the overall equipment. This leads to obstacles to the walking of people inside the factory during use, causing people to take detours when encountering the auger. Moreover, since the traditional conveying device auger on the market is a fixed structure, it is impossible to adjust the auger according to the actual situation on site during use.

[0005] In addition, the internal part of the auger device currently on the market is closed, which makes it impossible to clean up after the gypsum raw materials are transported, resulting in a waste of internal raw materials.

[0006] Therefore, we specially propose an automatic feeding device for gypsum mortar. Summary of the invention

[0014] Preferably, a first telescopic cylinder is fixedly installed at the lower part of the upper end of the bent pipe, and a chute plate is fixedly installed at the lower end of the arc plate. The telescopic cylinder principle of the first telescopic cylinder protrudes outward at one end and is slidably installed on the inner side of the chute plate.

[0015] By adopting the above technical solution, the first telescopic cylinder and the inclined slot plate can be used to allow the placement arc plate to rotate with the subsequent barrel, so that the raw materials inside the barrel can slide out smoothly.

[0018] Preferably, a symmetrical second telescopic cylinder is fixedly mounted on the upper portion of the upper end of the curved pipe, a push plate is fixedly mounted on the telescopic cylinder of the second telescopic cylinder, and the push plate can fit with the right side surface of the circular ring.

[0019] By adopting the above technical solution, the push plate can be used to push the ring by utilizing the second telescopic cylinder, and then the ring pushes the barrel to perform a reset operation.

[0020] Preferably, the upper end surface of the turntable is located between two adjacent cavity columns and a vertical rod is fixedly installed, and a limit plate is fixedly installed on the upper ends of the vertical rods. The limit plate is located between the barrel and the material tube, and circular through holes are evenly opened in a ring array from the upper end surface to the lower end surface of the limit plate.

[0027] By adopting the above technical solution, the accumulated materials can be continuously passed through the material box by using the sieve plate, and will not be uniformly accumulated inside the material box, resulting in the inability to transport the raw materials to the stirring device for subsequent operations.

[0028] Preferably, a servo motor is fixedly installed at the center position of the lower end of the interior of the material box, a reciprocating screw is fixedly installed on the output shaft of the servo motor, a sealing plate is fixedly installed on the circumferential surface of the reciprocating screw, a mounting buckle is fixedly installed on the right side of the material box, and the material pipe is slidably installed inside the mounting buckle.

[0029] By adopting the above technical solution, the servo motor can be used to drive the reciprocating screw to rotate. During the rotation, the sealing plate can block the discharge port of the material box, thereby ensuring that the raw materials inside the barrel are in the same state.

[0030] Compared with the prior art, the present invention has the following beneficial effects:

[0031] 1. The present invention, with the action of the internal thread on the upper part of the material pipe and the external thread on the lower end, allows the operator to adjust the overall height of the material pipe at any time and anywhere, thereby being able to meet the needs of stirring devices of any height; and in the process of use, due to the action of the bent pipe and the placement of the arc-shaped plate, the overall footprint of the device can be reduced, avoiding the device from affecting the walking back and forth of personnel inside the factory building; secondly, with the action of the mounting buckle, multiple material pipes can be combined and adjusted at different angles, and the direction of the material box will not change, thereby avoiding the inconvenience of personnel pouring raw materials into the material box; therefore, with the cooperation of the above-mentioned structure, it can be ensured that the present device is suitable for different environments and factory building heights, and will not occupy a large space.

[0032] 2. In the present invention, the positive magnetic ring and the negative magnetic ring can make the barrel slide smoothly into the inner side of the placement arc plate, and the first telescopic cylinder can make the placement arc plate tilt with the barrel, so as to ensure that the raw materials inside the barrel can smoothly enter the inside of the stirring device; then, under the scraper-like structure at the upper end of the inner part of the barrel, the raw materials inside the cavity column can be collected, thereby ensuring that there will be no accumulation of too much raw materials inside the structure.

[0033] 3. The present invention can reduce the overall height of the device under the action of the internal thread on the upper part of the material tube and the external thread on the lower end, thereby meeting the movement requirements of the device. BRIEF DESCRIPTION OF THE DRAWINGS

[0053] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0054] See also Figures 1 to 11 , the present invention provides a technical solution:

[0055] An automatic feeding device for gypsum mortar includes two brackets 1, and the lower end corners of the two brackets 1 are welded with high-strength aluminum alloy for installing a wheel hub 101. Then, two mounting screws 102 are rotatably installed on the front and rear brackets 1, and the front and rear ends of the two mounting screws 102 are located on the outside of the bracket 1. Then, nuts 103 are threadedly installed on the front and rear ends of the two mounting screws 102 to keep the mounting screws 102 in a fixed state without any rotation, because the bracket 1 and the mounting screw 102 are in a fixed state under the action of the nut 103.

[0056] Then, the main motor 201 is rotatably mounted on the circumferential surfaces of the two mounting screws 102. Figure 3 As shown, before assembling the bracket 1, the mounting screw 102 and the nut 103, the mounting screw 102 needs to be rotated through the protruding structures on both sides of the main motor 201, such as Figure 3 As shown, therefore, under the action of the mounting screw 102 , the output shaft of the main motor 201 can be placed in an upward position, and under the action of the wheel hub 101 , the main motor 201 can be moved.

[0057] A turntable 203 is fixedly mounted on the output shaft of the main motor 201. Four slide rod holes 204 are evenly arranged in an annular array from the upper end surface to the lower end surface of the turntable 203. Slide rods 205 are slidably mounted inside the slide rod holes 204 (wherein the top diameter of the slide rod 205 is larger than the slide rod hole 204). An annular pad 206 is fixedly mounted on the top of the slide rod 205. Figure 3 shown.

[0058] Four cavity columns 207 are evenly fixedly mounted in a circular array on the upper end surface of the rotating disk 203, and the cavity columns 207 correspond to the sliding rod holes one by one and are in a concentric state. Figure 2 As shown, moreover, the annular pad 206 is slidably mounted inside the cavity column 207.

[0059] Then, a quick-expanding cylinder 202 is fixedly installed on the right side surface of the main motor 201, and the telescopic rod of the quick-expanding cylinder 202 and the lower ends of the sliding rod 205 can be in corresponding states. Because during use, when the output shaft of the main motor 201 rotates with the turntable 203, it will rotate synchronously with the cavity column 207, and the cavity column 207 will rotate synchronously with the annular pad 206, and the annular pad 206 will rotate synchronously with the sliding rod 205, and the output shaft of the main motor 201 only rotates ninety degrees each time, that is, after each rotation, the sliding rod 205 is always above the quick-expanding cylinder 202.

[0060] Then, the telescopic rod of the fast telescopic cylinder 202 slides quickly, so that the slide bar 205 can slide upward. After the slide bar 205 slides upward, the annular pad 206 can slide synchronously inside the cavity column 207, thereby making the annular pad 206 slide upward, and then, after the upward impact force is gone, the annular pad 206 will move downward under the action of its own weight. After the annular pad 206 moves downward, it will move synchronously with the slide bar 205, thereby making the lower end of the slide bar 205 slide back into the slide bar hole 204 (it should be noted that the annular pad 206 will not slide out of the cavity column 207, so that the annular pad 206 can always be in a horizontal state, thereby ensuring that the lower end of the slide bar 205 slides back into the slide bar hole 204), and then, the barrel 3 is slidably installed inside the cavity column 207.

[0061] The upper end of the barrel 3 to the inside is a cavity structure for receiving gypsum raw materials, and the inner upper end of the barrel 3 is a blade-shaped structure, such as Fig.11 As shown, three first annular grooves 301 are evenly and vertically opened on the outer circumferential surface of the barrel 3 , and positive magnetic rings 302 are fixedly installed inside the first annular grooves 301 .

[0062] During use, the interior of the barrel 3 will be filled with about two-thirds of gypsum raw materials. At this time, when the annular gasket 206 slides upward inside the cavity column 207, it will push the barrel 3 to slide upward synchronously, thereby allowing the barrel 3 to slide out of the cavity column 207.

[0063] Two L-shaped brackets 6 are fixedly installed on the left side of the main motor 201, and a material box 5 is fixedly installed on the top of the two L-shaped brackets 6. The upper end surface of the material box 5 is open, and a double-opening cover is rotatably installed to block the upper end opening of the material box 5 to prevent dust of the raw material from floating out. Figure 1 shown.

[0064] The lower end of the material box 5 is a truncated cone structure, and a through round tube is fixedly installed at the lower end of the truncated cone structure, such as Figure 2 As shown, a servo motor 503 is fixedly installed at the lower end of the inner part of the circular tube, a reciprocating screw 504 is fixedly installed on the output shaft of the servo motor 503, and a sealing plate 505 is threadedly installed on the output shaft of the reciprocating screw 504, and the sealing plate 505 is a truncated cone with an inverted structure.

[0065] Therefore, during use, after the raw materials inside the material box 5 slide into the inside of the round tube, the servo motor 503 is started, and the output shaft of the servo motor 503 drives the reciprocating screw 504 to rotate. The reciprocating screw 504 can make the sealing plate 505 move downward, and then the sealing plate 505 can seal the upper end of the round tube, so that the gypsum raw material will not slide down (it should be noted that there are two outwardly protruding structures on the circumferential surface of the sealing plate 505, and the protruding structure extends downward by five centimeters, and a U-shaped groove matching the protruding structure is provided on the inner wall of the round tube. Therefore, when the reciprocating screw 504 rotates, the sealing plate 505 will not rotate synchronously with the reciprocating screw 504), thereby ensuring the consistency of the material inside the subsequent barrel 3.

[0066] Two symmetrical sieve plates 501 are fixedly installed inside the material box 5, and vibrators 502 are fixedly installed on the lower end surfaces of the sieve plates 501. Figure 5 shown.

[0067] During use, materials enter the material box 5 and will accumulate. Without interference, the materials will not smoothly enter the barrel 3 for subsequent operations. Therefore, starting the vibrator 502 can keep the sieve plate 501 in a vibrating state at all times, thereby allowing the materials on the sieve plate 501 to continuously enter the barrel 3 for subsequent operations.

[0068] Four vertical rods 208 are fixedly installed on the upper end surface of the rotating disk 203 between two adjacent cavity columns 207. A limit plate 209 is fixedly installed on the top of the vertical rods 208. Four through holes 210 are opened from the upper end surface to the lower end surface of the limit plate 209. Figure 1 As shown, each through hole 210 is in a through state with the cavity column 207, and the through hole 210 can be connected with the lower opening of the material box 5. Then, when the limiting plate 209 and the lower opening of the material box 5 are misaligned, the material at the lower end of the material box 5 will not slip out due to the blocking of the limiting plate 209, thereby ensuring the safety of the material.

[0069] Two support rods are fixedly installed on the right end surface of the material box 5, and a mounting buckle 7 is fixedly installed on the right end of the support rod. The material pipe 401 in the feeding assembly 4 is slidably installed inside the mounting buckle 7.

[0070] like Figure 6 and Figure 7 As shown, an internal thread 402 is provided at the upper inner end of the material tube 401, and an external thread 403 is provided at the outer outer side of the lower end of the material tube 401. Moreover, the diameter of the lower end of the material tube 401 is relatively small. Therefore, during use, the upper and lower ends of two identical material tubes 401 can be rotated and combined together, and multiple material tubes 401 can be combined into a length suitable for the operation.

[0071] Three second annular grooves 404 are evenly and vertically formed on the inner circumferential surface of the material tube 401 , and negative pole magnetic rings 405 are fixedly installed inside the second annular grooves 404 .

[0072] During use, the lower end of the material tube 401 will be in contact with the upper end surface of the limiting plate 209, and will be concentric with the rightmost cavity column 207. Figure 1 shown.

[0073] At this time, the barrel 3 inside the cavity column 207 will slide upward and pass through the through hole 210 into the interior of the material tube 401. Under the action of the positive magnetic ring 302 and the negative magnetic ring 405, the barrel 3 will continue to slide upward. Because the positive magnetic ring 302 and the negative magnetic ring 405 produce repulsion, it is equivalent to magnetic suspension, so that the barrel 3 can slide inside the combination of multiple material tubes 401 without falling down. The above-mentioned annular pad 206 only gives the barrel 3 an acceleration to enable the barrel 3 to move. Secondly, during use, the operator needs to carefully check the power supply status of the negative magnetic ring 405 one by one to avoid the situation where a certain negative magnetic ring 405 cannot operate.

[0074] like Figure 1 and Figure 8 As shown, a curved tube 406 is rotatably mounted on the upper end of the top material tube 401 (it should be noted that a second annular groove 404 is also provided on the inner wall of the curved tube 406, and a negative pole magnetic ring 405 is fixedly mounted inside the second annular groove 404), and an arc plate 407 is hingedly rotatably mounted at the right opening of the upper end of the curved tube 406, and two inclined groove plates 408 are fixedly mounted on the outer surface of the arc plate 407, and then a first telescopic cylinder 409 is fixedly mounted on the outer circumferential surface of the upper end of the curved tube 406, and the first telescopic cylinder 409 is located below the opening of the curved tube 406, as shown in FIG. Figure 8 As shown, the telescopic rod of the first telescopic cylinder 409 can slide between the two inclined slot plates 408, but the front and rear sides of the rightmost end of the telescopic rod of the first telescopic cylinder 409 protrude outward, and the protruding position is slidably installed inside the adjacent inclined slot plates 408.

[0075] Therefore, during use, the first telescopic cylinder 409 is started, and when the telescopic rod of the first telescopic cylinder 409 is retracted, the arc plate 407 is allowed to rotate clockwise under the action of the inclined slot plate 408. This is because the through slot provided on the inclined slot plate 408 is in an inclined state. When the telescopic rod of the first telescopic cylinder 409 is gradually retracted into the interior of the first telescopic cylinder 409, the arc plate 407 is allowed to rotate clockwise under the action of the inclined through slot.

[0076] Two limiting rings 410 are fixedly installed on the upper opening of the arc plate 407, and three convex grooves 411 are opened on the inner right circumferential surface of the arc plate 407. Slides 412 are slidably installed inside the convex grooves 411. A circular ring 413 is fixedly installed on the inner side of the three slides 412, and a buffer air cushion 414 is fixedly installed on the inner side of the circular ring 413. The buffer air cushion 414 is the same as the circular ring 413, and the center of the buffer air cushion 414 is a hollow structure to avoid affecting the falling of subsequent materials.

[0077] During use, the barrel 3 passes through the material pipe 401 and the curved pipe 406 and enters the interior of the curved plate 407. At this time, due to the fast speed of the barrel 3, its open end will collide with the buffer air cushion 414, and the buffer air cushion 414 will slide the ring 413 toward the right end of the curved plate 407. The ring 413 slides the slide 412 inside the convex groove 411. Under the action of the buffer air cushion 414, the barrel 3 can smoothly stop on the inner side of the curved plate 407.

[0078] Start the first telescopic cylinder 409, and the telescopic rod of the first telescopic cylinder 409 cooperates with the inclined slot plate 408 to allow the placement arc plate 407 to rotate clockwise, thereby changing the barrel 3 from a horizontal state to an inclined state, so that the raw materials inside the barrel 3 can be poured out into the interior of the stirring device. After completion, the first telescopic cylinder 409 cooperates with the inclined slot plate 408 to allow the placement arc plate 407 to restore the barrel 3.

[0079] Two second telescopic cylinders 415 are fixedly installed on the outer circumferential surface of the upper end of the curved pipe 406 at the upper end of the opening of the curved pipe 406 , and push plates 416 are fixedly installed on the telescopic rods of the second telescopic cylinders 415 , and the push plates 416 can contact the outer side surface of the ring 413 .

[0080] Start the second telescopic cylinder 415, the telescopic rod of the second telescopic cylinder 415 will bring the push plate 416 to quickly approach the ring 413, applying a driving force to the ring 413, and under the action of the driving force, the ring 413 will bring the buffer air cushion 414 to push the barrel 3, and the barrel 3 enters the interior of the curved pipe 406 under the action of the pushing force, and then slides into the interior of the cavity column 207 under the action of the positive magnetic ring 302 and the negative magnetic ring 405 and the action of its own weight.

[0081] With the cooperation of the above-mentioned devices, the raw materials can enter the interior of the barrel 3 without generating any dust, thus ensuring the factory environment. Then, when the barrel 3 works upward, the top opening can scrape the surface of the passing place to ensure the cleanliness of the interior of the equipment.

[0082] Working principle: First, the operator pours the raw materials into the material box 5, covers the lid and starts the vibrator 502 to make the screen plate 501 shake, then lets the raw materials fall to the bottom of the inside, starts the servo motor 503, and the output shaft of the servo motor 503 drives the reciprocating screw 504 to rotate. When the reciprocating screw 504 rotates, the sealing plate 505 moves upward, and the raw materials enter under the sealing plate 505. The servo motor 503 works in reverse, and the reciprocating screw 504 drives the sealing plate 505 to move downward.

[0083] The main motor 201 is started, and the output shaft of the main motor 201 drives the turntable 203, the cavity column 207, the vertical rod 208 and the limit plate 209 to rotate synchronously.

[0084] The cavity column 207 will rotate synchronously with the internal barrel 3 to the bottom of the material box 5, and the raw material will pass through the through hole 210 and the cavity column 207 and enter the interior of the barrel 3.

[0085] The output shaft of the main motor 201 drives the turntable 203 to continue to rotate, so that the barrel 3 filled with raw materials moves to the top of the fast telescopic cylinder 202.

[0086] Start the quick telescopic cylinder 202, the telescopic rod of the quick telescopic cylinder 202 pushes the slide bar 205 to move upward, the slide bar 205 pushes the annular pad 206 to slide inside the cavity column 207, the annular pad 206 pushes the barrel 3 to move upward inside the cavity column 207, and then enters into the interior of the material tube 401.

[0087] Under the action of the positive magnetic ring 302 and the negative magnetic ring 405, the barrel 3 continues to move upward along the path of the material tube 401, passes through the curved tube 406, and enters the interior of the arc plate 407. The opening of the barrel 3 contacts the buffer air cushion 414, and the buffer air cushion 414 is pushed to the right end. The buffer air cushion 414 moves synchronously to the right with the ring 413, thereby slowing down the barrel 3 until the barrel 3 stops moving.

[0088] Start the first telescopic cylinder 409, and the telescopic rod of the first telescopic cylinder 409 and the inclined slot plate 408 cooperate to allow the placement arc plate 407 to rotate clockwise, so that the opening of the barrel 3 can face downward, so that the raw materials inside the barrel 3 can be poured into the stirring device.

[0089] The arc plate 407 is placed in a restored state under the action of the first telescopic cylinder 409, and the second telescopic cylinder 415 is started. The telescopic rod of the second telescopic cylinder 415 moves the push plate 416 rapidly, applying an initial force to the ring 413.
