Description

Technical Field

[0001] The invention belongs to the technical field of masterbatch heat enhancer processing equipment, in particular to a raw material crushing and screening device for masterbatch heat enhancer production. Background Art

[0002] Masterbatch thermal enhancer is a functional additive that improves the heat resistance of plastic products through masterbatch technology. It usually uses carrier resin, heat-resistant additives, dispersants, etc. as core ingredients and is made into concentrated masterbatch form through a special process.

[0003] At present, when operators process carbon materials, they often use corresponding raw material crushing and screening devices to crush and screen the masterbatch heat enhancer raw materials into a form that meets the requirements. In actual use, the existing raw material crushing and screening devices are generally composed of a crushing mechanism and a screening mechanism. For the crushing mechanism, after the raw materials are crushed, the crushed raw materials will continuously fall on the screening mechanism. Since the discharge position of the crushing mechanism is fixed, the initial position of the crushed raw materials falling on the screening mechanism is also the same each time. For the screening mechanism, the crushed raw materials are mainly screened by the continuous vibration of the screen. The crushed raw materials contain small particles and large particles. For small particles, the impact of the small particles on the screen surface is relatively small. For large particles, since they continuously fall on the same position of the screen when they are first discharged, the long-term operation will cause the screen to be easily dented and the mesh to be deformed, thereby adversely affecting the long-term use of the screen.

[0004] At the same time, when the screening mechanism inside the crushing and screening device screens the crushed raw materials, the screen generally adopts an inclined design, so that large particles of raw materials can slide out along the inclined surface of the screen, while small particles of raw materials will pass through the screen and fall into the collection box. From the perspective of the inclined screen, the crushed raw materials generally fall on the top of the screen surface, because in this way the crushed raw materials can stay on the screen surface for a longer time during vibration screening, thereby improving the screening effect and quality of the crushed raw materials. At this time, due to the large amount of crushed raw materials, the small particles of raw materials screened by the screen and falling into the collection box are also large. However, as the crushed raw materials continue to vibrate and roll on the inclined upper surface of the screen, the small particles of raw materials falling into the collection box will continue to decrease, which will eventually make the crushed raw materials in the collection box unevenly distributed. As the production operation continues, the space inside the collection box cannot be used reasonably, and there will be a lot of crushed raw materials in one position of the collection box, while there will be relatively less crushed raw materials in other positions, which will affect the collection and use of the operators. Therefore, it is necessary to improve it. Summary of the Invention

[0016] The beneficial effects of the present invention are as follows:

[0017] 1. The present invention provides a fixed box, an air flow box, a movable box, a guide plate and an exhaust port. When the screen plate vibrates, the connecting plate will drive the movable box and the guide plate to vibrate. At this time, the crushed raw materials entering the feed pipe from the discharge pipe will fall between the multiple guide plates, and there are gaps between the multiple guide plates, so that small particle raw materials can fall into the interior of the movable box through the gaps and be discharged downward. Since the guide plates are designed to be inclined downward, the large particle raw materials will fall into the interior of the fixed box along the inclined surfaces between the guide plates and under the influence of vibration factors. Since the gas introduced into the air flow box by the air flow pipe is discharged intermittently, the gas discharged from the exhaust port is also intermittent. At this time, when the large particle raw materials are blown by the intermittent airflow, they will fall on different positions on the upper surface of the screen plate, thereby effectively avoiding the impact of large particle raw materials on the same position of the screen surface in the existing technology, thereby reducing the situation where the drop point on the upper surface of the screen plate is prone to local depression or serious deformation of the mesh under long-term operation.

[0018] 2. The present invention provides a rotating shaft, a vertical block, a movable frame, a first elliptical block and a second elliptical block. When the round rod rotates, the outer surface of the rotating shaft will continuously squeeze and push the inner surface of the vertical block. At this time, the vertical block will drive the connecting rod and the movable frame to move back and forth left and right. At this time, the outer surfaces of multiple first elliptical blocks will continuously squeeze and push the outer surfaces of multiple second elliptical blocks, thereby causing the placement rack and the collection box body to vibrate up and down as a whole. At this time, the crushed raw materials distributed inside the collection box body can be affected by the vibration factor, thereby achieving a uniform distribution of the crushed raw materials inside the collection box body, thereby improving the more rational utilization of the internal space of the collection box body.

[0019] 3. The present invention is provided with an air flow pipe, an arc-shaped groove, an air vent, a fan and an air vent screen. When the fan is running, gas will be extracted through the suction pipe and the gas will be introduced into the interior of the rotating cylinder through the exhaust pipe. When the round rod drives the rotating cylinder to rotate, the interior of the arc-shaped groove and the bottom end of the air flow pipe will intermittently overlap and interlace. When the arc-shaped groove and the bottom end of the air flow pipe are staggered, the gas inside the rotating cylinder can be discharged through the air vent and the air vent screen. When the interior of the arc-shaped groove and the bottom end of the air flow pipe begin to overlap, a part of the gas inside the rotating cylinder will enter the interior of the air flow pipe and finally be discharged from the exhaust port through the air flow box, thereby realizing intermittent discharge of the exhaust port gas, and finally realizing that the large particle raw materials discharged from the fixed box can be affected by the intermittent airflow and fall on different positions of the screen plate.

DETAILED DESCRIPTION

[0031] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. 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 making creative efforts are within the scope of protection of the present invention.

[0032] like Figures 1 to 10As shown, in an embodiment of the present invention, a raw material crushing and screening device for the production of masterbatch heat enhancers includes a base 1, a chassis 2 is fixedly installed on the top of the base 1, fixed blocks 3 are fixedly installed on both sides of the top of the inner cavity of the chassis 2, the number of the fixed blocks 3 is two, and a discharge pipe 4 is fixedly sleeved on the bottom between the two fixed blocks 3, a fixed box 5 located below the fixed block 3 is fixedly installed inside the chassis 2, an airflow box 6 is fixedly installed on the outer surface of the right side of the fixed box 5, a screen plate 12 is movably installed inside the chassis 2 and located below the fixed box 5, a connecting plate 8 is fixedly installed on the top of the upper surface of the screen plate 12, and the connecting plate 8 The other end of the movable box 7 is fixedly installed with a movable box 7, and the left sides of the movable box 7 are movably connected to the outer surfaces of the fixed box 5 and the airflow box 6 respectively. The top of the movable box 7 is fixedly sleeved with a feed pipe 10, the top of the feed pipe 10 passes through the discharge pipe 4 and extends to the inside of the discharge pipe 4 and is movably connected to the inner surface of the discharge pipe 4, and a guide plate 9 is fixedly installed on the top of the inner cavity of the movable box 7. An exhaust port 55 is opened between the bottom of the right side of the fixed box 5 and the left side of the airflow box 6. The front and rear sides of the airflow box 6 are fixedly sleeved with an airflow pipe 11, and the other end of the airflow pipe 11 passes through the airflow box 6 and the chassis 2 in sequence and extends to the outside of the chassis 2.

[0033] When the screen plate 12 vibrates to screen the carbon material raw materials, the movable box 7 will vibrate up and down as a whole through the connecting plate 8. At this time, the crushed raw materials that fall into the feed pipe 10 through the discharge pipe 4 will fall between the multiple guide plates 9. Since the multiple guide plates 9 are designed to be tilted downward, the small particles of raw materials will fall through the gaps between the guide plates 9, and the large particles of raw materials will slide along the outer surface between the guide plates 9 into the interior of the fixed box 5, and will eventually fall to the bottom of the inner cavity of the fixed box 5. At this time, the gas introduced by the two air flow pipes 11 will enter the interior of the air flow box 6 and be discharged from the exhaust port 55. At this time, the airflow discharged from the exhaust port 55 is intermittently discharged, so that The large particles of raw materials will be blown by the airflow intermittently. When the large particles of raw materials discharged from the bottom left side of the fixed box 5 are not blown by the airflow, the large particles of raw materials will fall on the position of the screen plate 12 close to the left side of the fixed box 5. When the large particles of raw materials discharged from the bottom left side of the fixed box 5 are blown by the airflow, the mass of each large particle of raw materials is different, which will cause the large particles of raw materials to move away from the fixed box 5 and fall on different positions of the screen plate 12. Such a design will effectively reduce the concentrated impact of large particles of raw materials on the same position of the upper surface of the screen plate 12, thereby avoiding the situation where the outer surface of the screen plate 12 is easily impacted by large particles of raw materials during long-term operation, causing mesh deformation or severe local depression.

[0034] A driving motor 13 is fixedly mounted in the middle of the right side of the chassis 2 , a rotating shaft 14 is fixedly sleeved on the other end of the output shaft of the driving motor 13 , and a rotating block 15 is fixedly sleeved on the other end of the rotating shaft 14 .

[0035] When the driving motor 13 is running, the rotating shaft 14 drives the rotating block 15 to rotate.

[0036] Among them, the top of the rotating block 15 is movably connected to a lifting plate 16, the rear end of the lifting plate 16 is fixedly connected to the back of the connecting plate 8, the top of the lifting plate 16 is fixedly connected to a flexible spring 17, and the other end of the flexible spring 17 is fixedly connected to the outside of the chassis 2.

[0037] When the rotating block 15 rotates 360 degrees, the outer surface of the rotating block 15 will continuously squeeze and push the lifting plate 16, so that the lifting plate 16 drives the connecting plate 8, the movable box 7 and the screen plate 12 to vibrate up and down. Due to the design of the flexible spring 17, the movable box 7, the connecting plate 8 and the screen plate 12 will have a good reset effect.

[0038] Among them, a power motor 18 is fixedly installed on the right side of the top front of the chassis 2, and the other end of the output shaft of the power motor 18 is fixedly sleeved with a round shaft 19. The other end of the round shaft 19 passes through the chassis 2 and extends to the back of the chassis 2 and is fixedly sleeved with a driving gear 20. The outer surface of the round shaft 19 is fixedly sleeved with a first crushing wheel 21 located between the fixed blocks 3.

[0039] When the power motor 18 is running, the circular shaft 19 will drive the driving gear 20 and the first crushing wheel 21 to rotate simultaneously.

[0040] Among them, the interior of the chassis 2 is movably sleeved with a rotating rod 22 located on the left side of the power motor 18. The rear end of the rotating rod 22 passes through the chassis 2 and extends to the back of the chassis 2 and is fixedly sleeved with a driven gear 24. The outer surface of the driven gear 24 is meshed with the outer surface of the driving gear 20. The outer surface of the rotating rod 22 is fixedly sleeved with a second crushing wheel 23 located between the fixed blocks 3 and on the left side of the first crushing wheel 21.

[0041] When the circular shaft 19 drives the driving gear 20 to rotate, the outer surface of the driving gear 20 will be meshed with the outer surface of the driven gear 24. At this time, the driven gear 24 will drive the rotating rod 22 and the second crushing wheel 23 to rotate together. At this time, through the cooperation between the first crushing wheel 21 and the second crushing wheel 23, the carbon material can be crushed.

[0042] Among them, the top of the chassis 2 is fixedly sleeved with a feeding pipe 25, the top of the feeding pipe 25 passes through the chassis 2 and extends to the top of the chassis 2, a baffle 26 is movably installed in the middle of the left side of the chassis 2, and a placement rack 28 located below the baffle 26 is movably installed inside the chassis 2. Side openings 46 are opened on both sides of the inner cavity of the chassis 2, and lifting blocks 47 located inside the side openings 46 are fixedly installed on both sides of the placement rack 28. The top of the lifting block 47 is fixedly connected to a connecting spring 48, and the top of the connecting spring 48 is fixedly connected to the top of the inner cavity of the side opening 46.

[0043] Due to the cooperation between the side opening 46 and the lifting block 47, the lifting and lowering movement of the placement rack 28 can be effectively limited, and due to the design of the connecting spring 48, the placement rack 28 and the lifting block 47 have a good reset effect.

[0044] Among them, second elliptical blocks 49 are fixedly installed on both sides of the bottom of the placement rack 28, and the top of the placement rack 28 is movably connected to the collection box body 30, and the front of the collection box body 30 is movably connected to the inner surface of the baffle 26.

[0045] The inner surface of the baffle 26 and the outer surface of the collection box body 30 are both smooth. Due to the design of the baffle 26, it can have a good blocking effect on the front of the collection box body 30, thereby preventing the collection box body 30 from falling off the top of the placement rack 28 when the placement rack 28 drives the collection box body 30 to vibrate up and down.

[0046] Among them, long grooves 27 are provided at the bottom of the front and back of the chassis 2, and a mobile rack 40 located below the placement rack 28 is movably installed inside the chassis 2.

The other end of the connecting rod 39 passes through the chassis 2 and extends to the right side of the chassis 2 and is fixedly installed with a vertical block 38. The first elliptical block 45 located between the second elliptical blocks 49 is fixedly installed on both sides of the top of the mobile rack 40. The right side of the mobile rack 40 is fixedly installed with a rigid spring 41 located on both sides of the connecting rod 39, and the other end of the rigid spring 41 is fixedly connected to the inner surface of the chassis 2.

[0047] Due to the cooperation between the long groove 27 and the moving block 29, the movement of the moving rack 40 can be effectively limited. When the moving rack 40 moves left and right, the outer surfaces of the multiple first elliptical blocks 45 will squeeze and push the outer surfaces of the multiple second elliptical blocks 49, which will cause the placement rack 28 and the collection box body 30 to vibrate up and down as a whole.

[0048] Among them, a fixed cylinder 31 is fixedly installed on the front and back of the right bottom of the chassis 2, and a rotating cylinder 32 is movably connected inside the fixed cylinder 31. A breathable mesh plate 54 is fixedly connected on both sides of the outer surface of the fixed cylinder 31. An arc groove 33 is provided in the middle of the outer surface of the rotating cylinder 32, and a breathable opening 34 is provided on the outer surface of the rotating cylinder 32 on both sides of the arc groove 33. There are two rotating cylinders 32, and a round rod 35 is fixedly installed on the corresponding side of the two rotating cylinders 32. The other end of the round rod 35 passes through the fixed cylinder 31 and extends to the outside of the fixed cylinder 31. There are two round rods 35, and the outer surfaces of the two round rods 35 are fixedly connected with a driven round wheel 36.

The right side of the fixed cylinder 31 is fixedly connected to the bottom end of the airflow pipe 11.

[0049] When the two round rods 35 rotate, they will drive the two rotating cylinders 32 to rotate. At this time, the interior of the arc groove 33 will be intermittently connected to the bottom end of the air flow tube 11, and the rotating shaft 37 will also rotate 360 degrees. At this time, the outer surface of the rotating shaft 37 will continuously squeeze and push the inner surface of the vertical block 38, so that the vertical block 38 can drive the connecting rod 39 and the movable frame 40 to move left and right.

[0050] Among them, the front and back of the chassis 2 are fixedly installed with fans 42 located on the right side of the long slot 27, the left side of the fan 42 is fixedly installed with an exhaust pipe 43, the front of the fan 42 is fixedly connected with an exhaust pipe 44, the other end of the exhaust pipe 44 passes through the fixed cylinder 31 and the rotating cylinder 32 in sequence and is movably connected to the inner surface of the rotating cylinder 32, and a dual-axis motor 50 is fixedly installed on the right side of the chassis 2, the other end of the output shaft of the dual-axis motor 50 is fixedly sleeved with a rotating rod 51, and the outer surface of the rotating rod 51 is fixedly sleeved with a driving round wheel 52, and the driving round wheel 52 is transmission-connected to the driven round wheel 36 through a transmission belt 53.

[0051] When the fan 42 is running, gas will be extracted through the exhaust pipe 43 and then introduced into the interior of the rotating cylinder 32 through the exhaust pipe 44. When the dual-axis motor 50 is running, the rotating rod 51 will drive the active circular wheel 52 to rotate. At this time, the active circular wheel 52 will drive the driven circular wheel 36, the circular rod 35 and the rotating shaft 37 to rotate through the transmission belt 53.

[0052] Working principle and usage process:

[0053] First, the operator starts the drive motor 13 and the power motor 18. The operation of the drive motor 13 will cause the rotating shaft 14 to drive the rotating block 15 to rotate. At this time, the outer surface of the rotating block 15 will continuously squeeze and push the lifting plate 16, so that the lifting plate 16 can drive the screen plate 12, the movable box 7 and the feed pipe 10 to vibrate up and down through the connecting plate 8. Due to the operation of the power motor 18, the circular shaft 19 will drive the first crushing wheel 21 and the driving gear 20 to rotate. At this time, the outer surface of the driving gear 20 will be meshed and connected with the outer surface of the driven gear 24, thereby driving the rotating rod 22 and the second crushing wheel 23 to rotate. Then the operator starts the fan 42 and the dual-shaft motor 50. The operation of the fan 42 will pass through the exhaust pipe. 43 extracts external air, and then introduces the gas into the interior of the rotating cylinder 32 through the exhaust pipe 44. Due to the operation of the dual-axis motor 50, the rotating rod 51 will drive the active circular wheel 52 to rotate. At this time, the active circular wheel 52 will drive the driven circular wheel 36, the circular rod 35 and the rotating cylinder 32 to rotate through the transmission belt 53. When the rotating cylinder 32 is rotating, the arc groove 33 and the bottom end of the airflow tube 11 are intertwined. At this time, the gas inside the rotating cylinder 32 will be discharged through the air vent 34 and the air permeable mesh plate 54. When the arc groove 33 intersects with the bottom end of the airflow tube 11, a part of the airflow inside the rotating cylinder 32 will enter the interior of the airflow box 6 through the airflow tube 11, and will eventually be discharged intermittently from the exhaust port 55.

[0054] When the two round rods 35 are rotating, the rotating shaft 37 will also rotate. At this time, the outer surface of the rotating shaft 37 will continuously rotate, squeeze and push the inner surface of the vertical block 38, thereby causing the connecting rod 39 and the movable rack 40 to move left and right. At this time, the outer surfaces of the multiple first elliptical blocks 45 will continuously squeeze and push the outer surfaces of the multiple second elliptical blocks 49, thereby causing vibration between the placement rack 28 and the collection box body 30.

[0055] Then, the operator can add the carbon raw material to be crushed into the interior of the chassis 2 through the feeding pipe 25, and then the carbon raw material will be crushed between the first crushing wheel 21 and the second crushing wheel 23, and then the crushed raw material will enter the interior of the feed pipe 10 through the discharge pipe 4, and will eventually fall between the multiple guide plates 9. Since there are gaps between the multiple guide plates 9, the small particles of raw material will pass through the gap and fall to the bottom of the inner cavity of the movable box 7, and then be screened by the screen plate 12 and fall into the interior of the collection box body 30, while the large particles of raw material will fall under the influence of the inclined guidance between the guide plates 9 and the vibration factors. To the interior of the fixed box 5, and since the airflow discharged from the exhaust port 55 is in an intermittent state, the large particle raw materials will be affected by the intermittent airflow, and discharged from the bottom of the left side of the fixed box 5 and fall on different positions on the outer surface of the screen plate 12. Finally, the screen plate 12 will further screen the large particle raw materials, and finally the large particle raw materials will slide down and be discharged from the bottom end of the upper surface of the screen plate 12. The crushed raw materials screened and collected by the screen plate 12 to the interior of the collection box body 30 will be affected by the vibration factor and evenly distributed inside the collection box body 30, thereby improving the utilization efficiency of the internal space of the collection box body 30.
