Description

Technical Field

[0002] In the manufacturing process of lost foam repair paste, polystyrene powder, filler and binder need to be mixed evenly to make the lost foam repair paste fine in texture and moderate in viscosity. However, when the polystyrene powder, filler and binder are mixed, bubbles are easily introduced during the mixing process, resulting in pores inside the repair paste, reducing its strength and sealing. In addition, there are also difficulties in feeding polystyrene powder. After the polystyrene powder is poured into the mixing box at one time, it is difficult to fully mix it with the filler and binder, and it is easy for the repair paste to be too thin in part and residual powder in part.

DETAILED DESCRIPTION

[0022] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0023] like Figures 1 to 13 As shown, the present invention provides a technical solution, a device for manufacturing a repair paste for lost foam, comprising a mixing box 1, a support leg 46 is fixedly connected to the bottom of the mixing box 1, a sleeve 2 is fixedly connected to the bottom of the mixing box 1, a motor 3 is fixedly connected to the bottom of the sleeve 2, an output end of the motor 3 extends to the inside of the sleeve 2 and is fixedly connected to a reciprocating screw 4, an outer wall of the reciprocating screw 4 is connected to a slider 5 through a screw nut pair, an adjusting component is arranged inside the sleeve 2, a support tube 9 is fixedly connected to the top of the slider 5, and the support tube 9 passes through the mixing box 1 and is connected to the It is a sliding connection, the top of the support cylinder 9 is fixedly connected to the feed cylinder 10, the top of the feed cylinder 10 is fixedly connected to the feed hopper 22, the feed hopper 22 is an inverted cone, the outer wall of the feed cylinder 10 is equidistantly fixedly connected to a plurality of lower hoppers 11, the outer wall of the lower hopper 11 is fixedly connected to a first stirring rod 12, a through groove 48 is provided inside the first stirring rod 12, a lower groove 47 is provided at the bottom of the first stirring rod 12, the lower groove 47 is communicated with the through groove 48, and a plurality of second stirring rods 18 are equidistantly fixedly connected to the bottom of the first stirring rod 12.

[0024] Through the above technical solution, the filler and the binder are poured into the mixing box 1, the motor 3 is started, the reciprocating screw 4 is driven to rotate counterclockwise, the slider 5 is driven to rotate counterclockwise, and the feed barrel 10 is driven to rotate counterclockwise, and the polystyrene powder is poured from the feed hopper 22. The polystyrene powder enters the feed barrel 10 along the feed hopper 22. As the feed barrel 10 rotates counterclockwise, the polystyrene powder is discharged along the lower hopper 11, the through groove 48, and the lower trough 47, thereby evenly entering the filler and the binder, and as the first stirring rod 12 and the second stirring rod 18 rotate, the polystyrene powder, the filler and the binder can be mixed more evenly.

[0025] Specifically, the adjustment component includes two slide grooves 8, which are symmetrically opened on the inner wall of the sleeve 2. The inner wall of the slider 5 is slidably connected with a block 6, and a first spring 7 is connected between the inner wall of the slider 5 and the block 6. One side of the block 6 is set as an inclined surface.

[0026] By the above technical solution, when the motor 3 is started and the reciprocating screw rod 4 is driven to rotate counterclockwise, the slider 5 rotates counterclockwise, driving the card block 6 to rotate counterclockwise. When the card block 6 rotates to the slide groove 8, the card block 6 is pushed into the slide groove 8 under the action of the first spring 7. As the slider 5 continues to rotate counterclockwise, the slide groove 8 presses against the inclined surface of the card block 6, thereby pushing the card block 6 to slide into the slider 5 and re-pressing the first spring 7. As a result, the reciprocating screw rod 4 can drive the slider 5 and the support tube 6 to rotate counterclockwise. 9. The feed barrel 10 rotates counterclockwise; start the motor 3, and when the reciprocating screw 4 is driven to rotate clockwise, the slider 5 follows the clockwise rotation, driving the block 6 to rotate clockwise. When the block 6 rotates to the slide groove 8, under the action of the first spring 7, the block 6 is pushed into the slide groove 8. As the slider 5 continues to rotate clockwise, the slide groove 8 presses against the straight surface of the block 6, making it impossible for the block 6 to rotate, thereby making the slider 5 move back and forth up and down on the reciprocating screw 4, driving the support barrel 9 and the feed barrel 10 to move back and forth up and down.

[0027] Specifically, a first diverter block 23 is fixedly connected to the bottom of the inner wall of the feed barrel 10, a slide rod 26 is slidably connected to the inner wall of the first diverter block 23, a second spring 24 is arranged inside the first diverter block 23, the bottom of the second spring 24 is fixedly connected to the first diverter block 23, the top of the second spring 24 is fixedly connected to the slide rod 26, six discharge ports 25 are equidistantly provided on the outer wall of the feed barrel 10, and the first diverter block 23 is arranged as a cone.

[0028] Through the above technical solution, part of the polystyrene powder entering from the feed barrel 10 falls on the bottom of the feed barrel 10, and slides to the six discharge ports 25 under the guidance of the first diversion block 23, thereby allowing the polystyrene powder to enter the filler and binder in a dispersed manner, thereby facilitating uniform mixing of the polystyrene powder, filler and binder.

[0029] Specifically, a plurality of second diverter blocks 27 are fixedly connected to the outer wall of the slide rod 26 at equal intervals. The second diverter block 27 is used in conjunction with the lower hopper 11. The second diverter block 27 is configured as a cone. Four groups of guide plates 28 are fixedly connected to the outer wall of the second diverter block 27 at equal intervals. Each group of guide plates 28 is arranged in an eight-shaped shape on the second diverter block 27.

[0030] Through the above technical solution, the polystyrene powder entering from the feed barrel 10 is blocked by the second diverter block 27, and the polystyrene powder is divided into four parts and flows to the lower hopper 11 through the provided guide plate 28 in cooperation with the second diverter block 27. The polystyrene powder entering the lower hopper 11 is discharged from the lower trough 47, so that it can be evenly sprinkled into the filler and the binder.

[0031] Specifically, the outer wall of the first stirring rod 12 is symmetrically fixedly connected to two fixed plates 13, the inner walls of the two fixed plates 13 are fixedly connected to the rotating shaft 14, the outer walls of the two rotating shafts 14 are rotatably connected to the lower pressure plate 15, the inner wall of the fixed plate 13 and the upper part of one side of the lower pressure plate 15 are fixedly connected to the top plate 16, the inner wall of the fixed plate 13 and the lower part of the other side of the lower pressure plate 15 are fixedly connected to the limit block 17, and the top of the limit block 17 is set as an inclined surface.

[0032] Through the above technical scheme, the motor 3 is started to drive the reciprocating screw 4 to rotate clockwise, so that the feed barrel 10, the first stirring rod 12, the fixed plate 13, and the lower pressure plate 15 move reciprocatingly up and down. When the fixed plate 13 moves upward, under the resistance of the lost foam repair paste, the lower pressure plate 15 rotates downward along the rotating shaft 14. After the lower pressure plate 15 is blocked by the limit block 17, the lost foam repair paste can slide from between the fixed plate 13 and the lower pressure plate 15. When the fixed plate 13 moves downward, under the resistance of the lost foam repair paste, the lower pressure plate 15 rotates upward along the rotating shaft 14. After the lower pressure plate 15 is blocked by the top plate 16, as the fixed plate 13 continues to move downward, the lower pressure plate 15 is driven to squeeze the lost foam repair paste, thereby squeezing out the air in the lost foam repair paste to prevent bubbles from remaining in the lost foam repair paste and affecting subsequent use.

[0033] Specifically, the outer wall of the feed barrel 10 is symmetrically fixedly connected to two connecting plates 32, and the inner wall of each connecting plate 32 is slidably connected to a plurality of sliding shafts 33. The outer wall of the sliding shaft 33 is fixedly connected to a second limit plate 36, and the second limit plate 36 is arranged inside the connecting plate 32 and is slidably connected to the connecting plate 32. A third spring 35 is sleeved on the sliding shaft 33, and the bottom of the third spring 35 is fixedly connected to the second limit plate 36, and the top is fixedly connected to the connecting plate 32. The top of the sliding shaft 33 is fixedly connected to the first limit plate 34, and the bottom is fixedly connected to the scraper 37.

[0034] Through the above technical solution, the motor 3 is started to drive the reciprocating screw 4 to rotate clockwise, so that the feeding barrel 10 moves back and forth up and down. When the feeding barrel 10 moves to the bottom, under the action of the third spring 35, the scraper 37 is pressed against the bottom of the mixing box 1. At this time, the reciprocating screw 4 is controlled by the motor 3 to rotate counterclockwise, driving the feeding barrel 10 to rotate counterclockwise, so that the scraper 37 rotates counterclockwise. With the counterclockwise rotation of the scraper 37, the lost foam repair paste can be prevented from sticking to the bottom of the mixing box 1 and being inconvenient to be removed.

[0035] Specifically, a feeding port 39 is provided at the bottom of the mixing box 1, and a baffle 40 is rotatably connected to the inner wall of the mixing box 1. A storage groove 43 used in conjunction with the baffle 40 is provided inside the mixing box 1. A spring sheet 41 is provided inside the storage groove 43. The spring sheet 41 is provided in a V-shape, one end of the spring sheet 41 is fixedly connected to the storage groove 43, and the other end is fixedly connected to the baffle 40. The scraper 37 is arranged in an arc shape, and a collecting plate 38 is fixedly connected to the inner wall of the scraper 37. The collecting plate 38 is arranged in a semicircular ring shape. A connecting block 44 is slidably connected to the inner wall of the scraper 37. A fourth spring 45 is provided inside the scraper 37. The top of the fourth spring 45 is fixedly connected to the scraper 37, and the bottom is fixedly connected to the connecting block 44. The bottom of the connecting block 44 is arranged as a symmetrical inclined surface. A card slot 42 is provided at the top of the baffle 40. The card slot 42 is used in conjunction with the connecting block 44. The elastic force of the fourth spring 45 is greater than the elastic force of the spring sheet 41.

[0036] Through the above technical solution, after the scraper 37 is pressed against the bottom of the mixing box 1, the scraper 37 is controlled to rotate counterclockwise. When the connecting block 44 moves to the top of the slot 42, the fourth spring 45 pushes the connecting block 44 to be inserted into the slot 42. At this time, as the scraper 37 rotates counterclockwise, the baffle 40 is driven to rotate counterclockwise, so that the baffle 40 enters the receiving groove 43 and presses the spring sheet 41. As the baffle 40 rotates counterclockwise, the discharge port 39 is opened, and the lost foam repair paste can flow out from the discharge port 39. After the spring sheet 41 is pressed to the limit, it is pushed under the extrusion of the slot 42. The inclined surface of the connecting block 44 moves upward, so that the connecting block 44 is retracted into the scraper 37, and the fourth spring 45 is compressed. As the scraper 37 rotates counterclockwise, the lost foam repair paste can be quantitatively discharged. As the lost foam repair paste flows out, when the surplus is small, the lost foam repair paste is difficult to flow out from the discharge port 39. At this time, as the scraper 37 rotates counterclockwise, it guides the lost foam repair paste, so that the lost foam repair paste can flow along the arc surface of the scraper 37 to the collecting plate 38, and the lost foam repair paste is moved to the discharge port 39 under the wrapping of the collecting plate 38, thereby facilitating the discharge of the lost foam repair paste.

[0037] Specifically, a mounting plate 21 is provided on the inner wall of the mixing box 1 and above the feed hopper 22, and four brackets 20 are fixedly connected to the outer wall of the mounting plate 21 at equal intervals, and the four brackets 20 are all fixedly connected to the mixing box 1, and a top rod 31 is symmetrically fixedly connected to the bottom of the mounting plate 21, and a top block 29 is fixedly connected to the top of the sliding rod 26. The top block 29 is configured as a cone, and four extrusion blocks 30 are fixedly connected to the top of the top block 29 at equal intervals, and the top of the extrusion block 30 is configured as a symmetrical inclined surface, and the bottom end of the top rod 31 is configured as a spherical shape, so that the extrusion block 30 can be used in conjunction with the top rod 31.

[0038] Through the above technical scheme, the motor 3 is started, and the feed barrel 10 is controlled to move upward to the highest point, and then the feed barrel 10 is controlled to rotate counterclockwise, driving the first diverter block 23 to rotate counterclockwise, causing the slide bar 26 to rotate counterclockwise, and driving the extrusion block 30 to rotate counterclockwise. As the extrusion block 30 rotates counterclockwise, when the inclined surface of the extrusion block 30 contacts the push rod 31, under the extrusion of the push rod 31, the extrusion block 30 is pushed to move downward, driving the slide bar 26 to move downward, and the second spring 24 is compressed. After the push rod 31 is separated from the extrusion block 30, under the action of the second spring 24, the slide bar 26 is pushed to move upward and reset, thereby reciprocating. As the feed barrel 10 rotates counterclockwise, the slide bar 26 is driven to vibrate up and down, causing the second diverter block 27 to vibrate up and down, thereby preventing the polystyrene powder from being stuck at the second diverter block 27 and unable to be discharged.

[0039] Specifically, the end of the first stirring rod 12 is fixedly connected with a collar 19 , the collar 19 fits the inner wall of the mixing box 1 , and the top of the collar 19 is set as a continuous curved surface.

[0040] Through the above technical solution, when the motor 3 is started and the feeding barrel 10 is controlled to move up and down, the sleeve ring 19 is driven to move up and down to prevent the lost foam repair paste from sticking to the inner wall of the mixing box 1 and causing waste. By setting the top of the sleeve ring 19 as a continuous curved surface, the lost foam repair paste is easy to slide down.

[0041] The repair paste manufacturing process using the repair paste manufacturing device for lost foam as described above comprises the following steps: S1. Pour the filler and the binder into the mixing box 1, start the motor 3, drive the reciprocating screw 4 to rotate counterclockwise, cooperate with the adjustment component to make the feed barrel 10 rotate counterclockwise, and pour the polystyrene powder into the feed hopper 22; S2, start the motor 3, drive the reciprocating screw 4 to rotate clockwise, make the fixed plate 13 move up and down reciprocatingly, cooperate with the top plate 16, make the lower pressure plate 15 continuously squeeze the lost foam repair paste, and squeeze out the air in the lost foam repair paste; S3, start the motor 3, drive the reciprocating screw 4 to rotate counterclockwise, cooperate with the connecting block 44, so that the discharge port 39 is intermittently opened, and the lost foam repair paste is wrapped by the collecting plate 38. Under the wrapping of the collecting plate 38, the lost foam repair paste moves to the discharge port 39, and the motor 3 controls the ring 19 to move up and down to scrape off the lost foam repair paste stuck on the inner wall of the mixing box 1.

[0042] Working principle: When in use, fillers, adhesives, etc. are poured into the mixing box 1, and the motor 3 is started to drive the reciprocating screw 4 to rotate clockwise. At the same time, the slider 5 follows the clockwise rotation, driving the block 6 to rotate clockwise. When the block 6 rotates to the slide groove 8, under the action of the first spring 7, the block 6 is pushed into the slide groove 8. As the slider 5 continues to rotate clockwise, the slide groove 8 presses against the straight surface of the block 6, so that the block 6 cannot rotate, thereby making the slider 5 reciprocate up and down on the reciprocating screw 4, driving the support cylinder 9 and the feed cylinder 10 to move reciprocally up and down. When feeding polystyrene powder, the feed cylinder 10 is controlled by the motor 3 to move to the highest point, and the motor is started. 3, drives the reciprocating screw rod 4 to rotate counterclockwise, makes the slider 5 rotate counterclockwise, drives the card block 6 to rotate counterclockwise, when the card block 6 rotates to the slide groove 8, under the action of the first spring 7, pushes the card block 6 into the slide groove 8, as the slider 5 continues to rotate counterclockwise, the slide groove 8 presses against the inclined surface of the card block 6, thereby pushing the card block 6 to slide into the slider 5, re-pressing the first spring 7, thereby while the reciprocating screw rod 4 rotates counterclockwise, it can drive the slider 5, the support cylinder 9, and the feed cylinder 10 to rotate counterclockwise, pour the polystyrene powder from the feed hopper 22, the polystyrene powder enters the feed cylinder 10 along the feed hopper 22, and the polystyrene powder entering from the feed cylinder 10 The polystyrene powder is blocked by the second diverter block 27. The guide plate 28 is arranged to cooperate with the second diverter block 27 to divide the polystyrene powder into four parts and flow to the lower hopper 11. The polystyrene powder entering the lower hopper 11 is discharged from the lower trough 47, so that it can be evenly sprinkled into the filler and the binder. The polystyrene powder falling from the second diverter block 27 falls on the bottom of the feed barrel 10 and slides to the six discharge ports 25 under the guidance of the first diverter block 23, so that the polystyrene powder enters the filler and the binder in a dispersed manner, which is convenient for the polystyrene powder, the filler, and the binder to be evenly mixed. As the feed barrel 10 rotates counterclockwise, the first diverter block is driven to rotate. 23 rotates counterclockwise, causing the slide bar 26 to rotate counterclockwise, driving the extrusion block 30 to rotate counterclockwise. As the extrusion block 30 rotates counterclockwise, when the inclined surface of the extrusion block 30 contacts the ejector pin 31, the extrusion block 30 is pushed downward under the extrusion of the ejector pin 31, driving the slide bar 26 to move downward, pressing the second spring 24. After the ejector pin 31 is separated from the extrusion block 30, the slide bar 26 is pushed upward and reset under the action of the second spring 24, thus reciprocating. As the feeding barrel 10 rotates counterclockwise, the slide bar 26 is driven to vibrate up and down, causing the second diverter block 27 to vibrate up and down, thereby preventing the polystyrene powder from being stuck at the second diverter block 27 and being unable to be discharged.The motor 3 is started to drive the reciprocating screw rod 4 to rotate clockwise, so that the feed barrel 10, the first stirring rod 12, the fixed plate 13, and the lower pressing plate 15 move up and down reciprocatingly. When the fixed plate 13 moves upward, under the resistance of the lost foam repair paste, the lower pressing plate 15 rotates downward along the rotating shaft 14. After the lower pressing plate 15 is blocked by the limit block 17, the lost foam repair paste can slide from between the fixed plate 13 and the lower pressing plate 15. When the fixed plate 13 moves downward, under the resistance of the lost foam repair paste, the lower pressing plate 15 rotates upward along the rotating shaft 14. After the lower pressing plate 15 is blocked by the top plate 16, as the fixed plate 13 continues to move downward, the lower pressing plate 1 5. The lost foam repair paste is squeezed to squeeze out the air in the lost foam repair paste to prevent bubbles from remaining in the lost foam repair paste and affecting subsequent use. When the lost foam repair paste in the mixing box 1 needs to be taken out, the motor 3 is started to control the feed cylinder 10 to move to the bottom. Under the action of the third spring 35, the scraper 37 is pressed against the bottom of the mixing box 1. At this time, the reciprocating screw rod 4 is controlled by the motor 3 to rotate counterclockwise, driving the feed cylinder 10 to rotate counterclockwise, so that the scraper 37 rotates counterclockwise. With the counterclockwise rotation of the scraper 37, the lost foam repair paste can be prevented from sticking to the bottom of the mixing box 1 and being inconvenient to be taken out. With the counterclockwise rotation of the scraper 37, when the connecting block 44 moves to When the top of the slot 42 is reached, the fourth spring 45 pushes the connecting block 44 to be inserted into the slot 42. At this time, as the scraper 37 rotates counterclockwise, the baffle 40 is driven to rotate counterclockwise, so that the baffle 40 enters the receiving groove 43 and presses the spring sheet 41. As the baffle 40 rotates counterclockwise, the discharge port 39 is opened, and the lost foam repair paste can flow out from the discharge port 39. After the spring sheet 41 is pressed to the limit, the inclined surface of the connecting block 44 is pushed upward under the extrusion of the slot 42, so that the connecting block 44 is retracted into the scraper 37 and the fourth spring 45 is pressed. As a result, when the scraper 37 rotates counterclockwise, the lost foam repair paste can be quantitatively discharged. When the residual amount of the lost foam repair paste is small, it is difficult for the lost foam repair paste to flow out from the discharge port 39. At this time, as the scraper 37 rotates counterclockwise, it guides the lost foam repair paste, so that the lost foam repair paste can flow along the arc surface of the scraper 37 to the collecting plate 38, and the lost foam repair paste is moved to the discharge port 39 under the wrapping of the collecting plate 38, thereby facilitating the discharge of the lost foam repair paste. In order to prevent the lost foam repair paste from sticking to the inner wall of the mixing box 1 and causing waste, the motor 3 is started to control the feeding cylinder 10 to move up and down, driving the sleeve 19 to move up and down. By setting the top of the sleeve 19 as a continuous curved surface, it is convenient for the lost foam repair paste to slide down. ;
