Description

Technical Field

[0001] The present invention relates to the technical field of environmental protection equipment, and in particular to a production device for pre-dispersed masterbatch capable of improving production efficiency. Background Art

[0002] Pre-dispersed masterbatch is a raw material used in the production of rubber. Typically, pre-dispersed masterbatch is made by grinding, stirring, and mixing various solid additives such as sulfur, EPDM rubber, and silicone, then mixing them with various solutions such as vinyl acetate, saturated fatty acid zinc, and dibutyl phthalate, followed by drying and granulation. Currently, equipment for producing pre-dispersed masterbatch includes grinders, mixers, filters, dryers, and granulators. Due to limitations in production technology, grinders, mixers, and filters are all relatively independent devices, often interconnected by complex piping, pumps, fans, and conveyor belts to produce the pre-dispersed masterbatch. Due to the complex connections between the devices and the relatively independent mechanical equipment, synergy and interchangeability between the devices are generally low. Furthermore, these devices occupy a large area, requiring constant debugging to ensure interoperability, resulting in low production efficiency and thus impacting the company's economic benefits. Therefore, there is an urgent need for a pre-dispersed masterbatch production device with an integrated structure that features grinding, stirring, and mixing functions, coordinated with the dryer and granulator to achieve the purpose of producing pre-dispersed masterbatch. Summary of the Invention

[0003] In response to the above problems, the present invention provides a production equipment for pre-dispersed masterbatch that can improve production efficiency. It can realize the functions of grinding, stirring and mixing. The equipment places the mixed melt on a granulation template and then sends it into a dryer for drying and granulation, thereby improving the production efficiency of the pre-dispersed masterbatch.

[0004] The technical solution of the present invention is: a production equipment for pre-dispersed masterbatch that can improve production efficiency, including a stirring device, a rolling device, and a mixing device that are fixedly connected and connected in sequence along the vertical direction, a stirring component is provided at the central axis of the stirring device, a solid material feeding port is provided at the top of the stirring device, a serpentine protrusion is provided on the inner wall of the stirring device along the four sides of the stirring component, a blade is provided on the side of the serpentine protrusion facing the stirring component, a group of mutually meshing rolling gears with uneven tooth surfaces are provided laterally in the rolling device, a flexible filter is provided below the rolling gear, and a flexible filter is provided on the flexible filter. A chain is provided, which is fixedly connected to the inner wall of the rolling device. A swinging piece is provided between the rolling gear and the flexible filter screen. The swinging piece is pressed and connected to the tooth surface of the rolling gear and swings up and down in the vertical direction. The swinging piece is socketed with the flexible filter screen. The rolling gear is connected to the first driving motor. When the first driving motor drives the rolling gear to rotate, the flexible filter screen can swing laterally. A stirring rod is laterally provided in the mixing device. A plurality of liquid material feed ports are provided at one end of the mixing device, and a discharge port is provided at the opposite end to the liquid material feed port. The discharge port is provided with a pump body, and the pump body is provided with a discharge nozzle.

[0005] Furthermore, the stirring assembly includes a second drive motor disposed at the top of the stirring device, the output shaft of the second drive motor being fixedly connected to a support rod, the support rod being vertically inserted along the central axis of the stirring device, a plurality of serpentine rods being evenly arranged along the circumference of the support rod on the outer wall of the stirring device, the serpentine rods extending axially along the support rod, a fixed rod for supporting the serpentine rods being disposed between the serpentine rods and the support rods, a serpentine blade being disposed on the serpentine blade, the curvature of the serpentine blade corresponding to the curvature of the serpentine protrusion. Solid material enters the stirring device through a solid material feed port, the serpentine blade on the serpentine rod being able to interact with the blade on the serpentine protrusion, and under the drive of the second drive motor, the solid material is stirred while being cut while unevenly sized solid material is being cut, and at the same time, the solid material is continuously struck by the centrifugal force of the serpentine blade, so that the solid material is continuously stirred and cut within the stirring device, so that the solid material can be quickly and evenly cut and mixed.

[0006] Furthermore, the rolling gear includes a fixed shaft and a rotating shaft arranged parallel to each other, a plurality of cams fixedly arranged axially on the fixed shaft, and a plurality of cams fixedly arranged axially on the rotating shaft, the cams and the cams meshing with each other, both ends of the fixed shaft are fixed to the inner wall of the rolling device, one end of the rotating shaft is nested in the inner wall of the rolling device through a bearing, and the other end extends out of the outer end of the rolling device and is fixedly connected to the first drive motor, and a guide plate is arranged directly above the rolling gear, and the guide plate is fixed to the inner wall of the rolling device. The guide plates are two fixed plates symmetrically arranged on both sides of the inner wall of the rolling device, with the bevel facing the position where the cams and the cams mesh with each other. The guide plates can guide the solid material flowing out of the stirring device to the rolling gear, on the one hand, playing a role of diversion, and on the other hand, can slow down the speed at which the solid material reaches the rolling gear, so as to prevent the solid material from forming a tower-like accumulation on the rolling gear, thereby preventing the tower-like accumulation from clogging the meshing cams and cams. Among them, there are gaps between the several cams on the rotating shaft and the several concave wheels on the fixed shaft to prevent the cams, concave wheels, and cams from getting stuck, thereby reducing the wear rate of the machine; at the same time, the gaps between them can ensure that the solid materials that have been stirred and mixed can pass through the rolling gear smoothly.

[0007] Furthermore, a groove is provided on the circumference of the cam, and a slide rail is provided on the circumference of the cam. The slide rail is placed in the groove, and the slide rail and the groove are loosely matched. A circle of raised slide rails is provided on the circumference of the cam, while a recessed groove is provided on the circumference of the cam, allowing the slide rail and the groove to mesh with each other. This structure changes the existing common gear meshing method, preventing the occurrence of wear and slip between the teeth when the gears mesh with each other, thereby reducing the mechanical failure rate. In addition, because the slide rail is integrally formed and the slide rail surface is smooth and continuous, it can crush the solid materials passing through while avoiding the damage to the motor caused by the tooth biting phenomenon of traditional gears.

[0008] Furthermore, a fixed block is provided at one end of the flexible filter screen facing the concave wheel, a chain A is vertically connected to the fixed block, the other end of the chain A relative to the fixed block is connected to a side wall connecting ear A, the side wall connecting ear A is fixed to the inner wall of the rolling device, the end of the flexible filter screen facing the cam is fixedly connected to a swing block, a limiting groove is provided at the central axis of the swing block, chains B are fixedly connected at both ends of the swing block, one end of the chain B is connected to a side wall connecting ear B, the side wall connecting ear B is fixed to the inner wall of the rolling device, one end of the swing member passes through the side wall connecting ear B and extends into the limiting groove, the other end of the swing member presses against the slide rail and is slidably connected to the slide rail. The flexible filter screen is provided so that the solid material on the filter screen can vibrate horizontally and vertically with the fluctuation of the flexible filter screen, thereby increasing the contact area between the solid material and the flexible filter screen, and at the same time, due to the dual effects of horizontal and vertical directions, the solid material can evenly enter the mixing device, so that it is fully mixed with other liquid materials under the action of the mixing device, thereby improving the mixing efficiency between materials. The swing block and the fixed block are both fixed to the ends of the flexible filter screen, and the swing block and the fixed block are respectively connected to the corresponding side wall connecting ears by a chain. Since the chain suspends the flexible filter screen in the rolling device, when the flexible filter screen is subjected to a small thrust, it will swing freely in the rolling device. The swing member and the slide rail of the cam contact and press each other, so that when the first drive motor drives the rotating shaft to rotate, the cam rotates accordingly, and the friction between the swing member and the slide rail causes the swing member to swing, and the swing is transmitted to the swing block through the swing member. Since the chain can swing freely under the action of the swing force, the flexible filter screen can swing freely.

[0009] Furthermore, pulleys A and B are symmetrically arranged on both sides of the pressing end of the swing member and the slide rail, forming a sliding space between pulleys A and B. The slide rail is placed in the sliding space. The side wall connecting ear B is a hollow structure, and a limit platform is provided in the side wall connecting ear B. A spring is fixedly connected between the limit platform and the top of the inner wall of the side wall connecting ear B. The swing member penetrates the spring and the limit platform and extends out of the outer end of the side wall connecting ear B. A contact ball is provided on the end of the swing member that contacts the limit groove. The sliding space formed between pulleys A and B can accommodate the slide rail, and the opposing sides of pulleys A and B can be mutually limited by the two side surfaces of the slide rail to prevent the slide rail from jumping out of the sliding space. The swing member can be pressed against the slide rail by the spring. At the same time, because the spring has a restoring force, the swing member can drive the swing block to swing under the action of the restoring force. The contact ball forms point contact between the swinging piece and the limit groove. This point contact method increases the swing frequency of the swing block, thereby increasing the swing frequency of the flexible filter screen, thereby reducing the passage time of solid materials through the flexible filter screen and improving the material passing efficiency.

[0010] Furthermore, the flexible filter has a wavy structure and is provided with a plurality of filter holes. The wavy structure can mitigate the impact of materials on the flexible filter, preventing the materials from splashing due to the swinging of the flexible filter, thereby reducing the generation of solid dust. The filter holes are designed to allow solid materials to pass through smoothly.

[0011] Furthermore, a third drive motor is connected to one end of the stirring rod, which is fixedly connected to the outer wall of the mixing device. The stirring rod is provided with a plurality of contact blocks along its axial direction, with the contact blocks being cross-distributed on both sides of the stirring rod. By energizing the third drive motor, the stirring rod is activated, thereby mixing the liquid material with the solid material. Simultaneously, the plurality of staggered contact blocks provided on the stirring rod ensure sufficient mixing of the solid material and the liquid material, thereby increasing the mixing efficiency between the materials.

[0012] Furthermore, the device further comprises a transverse reciprocating motion device fixedly connected to the pump body, a discharging nozzle being transversely slidably connected to the transverse reciprocating motion device, a hose being provided between the discharging nozzle and the pump body, and a valve body being provided on the hose. The transverse reciprocating motion device is capable of driving the discharging nozzle to perform transverse reciprocating motion, thereby ensuring uniform discharging of the material from the discharging nozzle and preventing accumulation of the mixture at the discharging port. The discharging nozzle and the pump body are flexibly connected via the hose, thereby ensuring that the reciprocating motion of the discharging nozzle is not affected by the position of the pump body.

[0013] Furthermore, the transverse reciprocating motion device includes a hollow shell, in which a fourth drive motor is provided inside the shell, a turntable is fixedly connected to the output shaft of the fourth drive motor, a protrusion is provided on the turntable at a position away from the center of the circle, a connecting rod is hinged on the protrusion, a slider is provided at one end of the connecting rod, the slider is fixedly connected to the outer wall of the discharge nozzle, a transverse sliding rail is provided in the shell, and the slider is placed in the transverse sliding rail. One of the movement principles of the transverse reciprocating motion device is the crank slider mechanism principle, wherein the fourth drive motor, the turntable, the eccentric protrusion, the connecting rod, and the slider constitute a crank slider mechanism, and the slider moves back and forth in the transverse sliding rail, so that the slider drives the discharge nozzle to reciprocate on the transverse sliding rail. The crank slider mechanism has a simple structure, uses fewer mechanical parts to achieve the purpose of reciprocating motion, and prevents material accumulation at the discharge port.

[0014] Compared with the prior art, the beneficial effect of the present invention is that the present invention integrates the structure design of the stirring device, the rolling device and the mixing device to realize the functions of grinding, stirring and mixing. The device places the mixed molten material on the granulation template, and then sends it to the dryer through the conveyor belt for drying and granulation, thereby shortening the stirring and mixing time of the existing equipment, thereby improving the production efficiency of the pre-dispersed masterbatch. Among them, the serpentine protrusion in the stirring device is equipped with a serpentine blade, which can cut the solid material inside the rolling device when the stirring component rotates, thereby reducing the particle diameter of the solid material, thereby enhancing the mixing effect between the solid materials. Among them, the solid materials are at least two types, which can be any two or three of sulfur, EPDM rubber and silicone. On the one hand, the flexible filter screen can buffer the force of the solid material facing the mixing device, so that the solid material slowly enters the mixing device, thereby increasing the reaction time of the solid material and the liquid material, thereby enhancing the mixing effect.

Figure 6The flexible filter screen 5 shown in the figure is provided with a chain on the flexible filter screen 5, which is fixedly connected to the inner wall of the rolling device 2, and a swinging member 31 is provided between the rolling gear 4 and the flexible filter screen 5, and the swinging member 31 is tightly connected to the tooth surface of the rolling gear 4 and swings up and down in the vertical direction. The swinging member 31 is sleeved on the flexible filter screen 5, and the rolling gear 4 is connected to the first drive motor 6. When the first drive motor 6 drives the rolling gear 4 to rotate, the flexible filter screen 5 can swing laterally, and a stirring rod 7 is laterally arranged in the mixing device 3, and a plurality of liquid material feed ports 8 are provided at one end of the mixing device 3, and a discharge port is provided at the opposite end of the liquid material feed port 8, and a pump body 9 is provided at the discharge port, and the pump body 9 is provided with a discharge nozzle 10.

[0029] The present embodiment carries out integrated structural design with stirring device 1, rolling device 2, mixing device 3, realizes the function of grinding, stirring, mixing, the molten material after mixing is placed on the granulation template by this equipment, is then sent into dryer by conveyor belt 49 and is dried and granulated, and then the stirring, mixing time of existing equipment are shortened, thereby improve the production efficiency of pre-dispersed masterbatch.Wherein, serpentine blade is installed on the serpentine protrusion 18 in stirring device 1, and this blade can cut the solid material inside rolling device 2 when stirring assembly 11 rotates, thereby reduces the particle diameter of solid material, and then strengthens the mixing effect between solid material.Wherein, solid material is at least two kinds, can be any two or three kinds in sulphur, EPDM rubber, silicone.On the one hand, flexible filter screen 5 can buffer the power of solid material towards mixing device 3, makes solid material slowly enter mixing device 3, thereby increases the reaction time of solid material and liquid material, and then strengthens mixing effect, wherein, liquid material is liquid material such as vinyl acetate, saturated fatty acid zinc, dibutyl phthalate.

[0030] refer to Figure 2 、 Figure 3The stirring assembly 11 includes a second drive motor 13 arranged at the top of the stirring device 1, and a support rod 14 is fixedly connected to the output shaft of the second drive motor 13. The support rod 14 is vertically inserted along the central axis of the stirring device 1. A plurality of serpentine rods 15 are evenly arranged along the circumference of the support rod 14 in the stirring device 1. The serpentine rod 15 extends axially along the support rod 14. A fixed rod 16 for supporting the serpentine rod 15 is provided between the serpentine rod 15 and the support rod 14. A serpentine knife 17 is provided on the serpentine rod 15, and the bending direction of the serpentine knife 17 corresponds to the bending direction of the serpentine protrusion 18. The solid material enters the stirring device 1 through the solid material feed port 12, and the serpentine knife 17 on the serpentine rod 15 can interact with the blade on the serpentine protrusion 18. Driven by the second drive motor 13, the solid material is stirred while the solid material of uneven size is cut. At the same time, the solid material is continuously hit by the blade on the serpentine protrusion 18 under the action of the centrifugal force of the serpentine knife 17, so that the solid material is continuously stirred and cut in the stirring device 1, so that the solid material can be quickly and evenly cut and mixed.

[0031] refer to Figure 4 、 Figure 5 The rolling gear 4 includes a fixed shaft and a rotating shaft arranged parallel to each other. A plurality of concave wheels 19 are fixedly arranged along the axial direction on the fixed shaft, and a plurality of cams 20 are fixedly arranged along the axial direction on the rotating shaft. The concave wheels 19 and the cams 20 are meshed with each other. Both ends of the fixed shaft are fixed on the inner wall of the rolling device 2. One end of the rotating shaft is nested on the inner wall of the rolling device 2 through a bearing, and the other end extends out of the outer end of the rolling device 2 and is fixedly connected to the first drive motor 6. A Figure 1 The guide plates 21 are shown fixed to the inner wall of the rolling device 2. The guide plates 21 are two symmetrically positioned downwardly, with their beveled edges facing the meshing position of the cams 20 and concave wheels 19. The guide plates 21 direct the solid material flowing out of the stirring device 1 onto the rolling gear 4, both diverting it and slowing it down as it reaches the rolling gear 4. This prevents the solid material from accumulating in a tower-like pattern on the rolling gear 4 and blocking the meshing cams 20 and concave wheels 19. Clearances exist between the cams 20 on the rotating shaft and the concave wheels 19 on the fixed shaft, preventing jamming between the cams 20, the concave wheels 19, and the cams 20 and 19, thereby reducing wear on the machine. Furthermore, the clearances ensure that the stirred and mixed solid material passes smoothly through the rolling gear 4.

[0032] A groove 22 is provided on the circumference of the cam 19, and a slide rail 23 is provided on the circumference of the cam 20. The slide rail 23 is placed in the groove 22, and the slide rail 23 and the groove 22 are loosely matched. A circle of raised slide rails 23 is provided on the circumference of the cam 20, and a recessed groove 22 is provided on the circumference of the cam 19, so that the slide rail 23 and the groove 22 mesh with each other. This structure changes the existing common gear meshing method, avoiding the mutual wear and slippage between the teeth when the gears mesh with each other, thereby reducing the mechanical failure rate. In addition, because the slide rail 23 is integrally formed and the surface of the slide rail 23 is smooth and continuous, it can crush the solid materials passing through while avoiding the damage to the motor caused by the tooth biting phenomenon of traditional gears.

[0033] refer to Figure 7 、 Figure 8 A fixed block 24 is provided at the end of the flexible filter screen 5 facing the concave wheel 19, and a chain A25 is vertically connected to the fixed block 24. The other end of the chain A25 relative to the fixed block 24 is connected to a side wall connecting ear A26, and the side wall connecting ear A26 is fixed to the inner wall of the rolling device 2. The end of the flexible filter screen 5 facing the cam 20 is fixedly connected to a swing block 27, and a limiting groove 28 is provided at the central axis of the swing block 27. Chains B29 are fixedly connected at both ends of the swing block 27, and one end of the chain B29 is connected to the side wall connecting ear B30. The side wall connecting ear B30 is fixed to the inner wall of the rolling device 2, and one end of the swinging member 31 passes through the side wall connecting ear B30 and extends into the limiting groove 28. The other end of the swinging member 31 presses the slide rail 23 and is slidably connected to the slide rail 23. The flexible filter screen 5 is provided so that the solid material on the filter screen can vibrate laterally and longitudinally with the fluctuation of the flexible filter screen 5, thereby increasing the contact area between the solid material and the flexible filter screen 5. At the same time, due to the dual effects of the horizontal and vertical directions, the solid material can evenly enter the mixing device 3, so that it is fully mixed with other liquid materials under the action of the mixing device 3, thereby improving the mixing efficiency between the materials. Among them, the swing block 27 and the fixed block 24 are both fixed to the ends of the flexible filter screen 5, and the swing block 27 and the fixed block 24 are respectively connected to the corresponding side wall connecting ears by chains. Because the chain suspends the flexible filter screen 5 in the rolling device 2, when the flexible filter screen 5 is subjected to a small thrust, it will swing freely in the rolling device 2. The swinging member 31 and the slide rail 23 of the cam 20 contact and press each other, so that when the first drive motor 6 drives the rotating shaft to rotate, the cam 20 rotates accordingly, and the friction between the swinging member 31 and the slide rail 23 causes the swinging member 31 to swing, and the swing is transmitted to the swing block 27 through the swinging member 31. Since the chain can swing freely under the action of the swinging force, the flexible filter screen 5 can swing freely.

[0034] refer to Figure 8Pulleys A32 and B33 are symmetrically arranged on both sides of the pressing end of the swing member 31 and the slide rail 23. A sliding space is formed between the pulleys A32 and B33. The slide rail 23 is placed in the sliding space. The side wall connecting ear B30 is a hollow structure, and a limiting platform 34 is provided in the side wall connecting ear B30. A spring 35 is fixedly connected between the limiting platform 34 and the top of the inner wall of the side wall connecting ear B30. The swing member 31 penetrates into the spring 35 and the limiting platform 34 and extends out of the outer end of the side wall connecting ear B30. A contact ball 36 is provided on the end of the swing member 31 that contacts the limiting groove 28. The sliding space formed between pulley A32 and pulley B33 can accommodate slide rail 23, while the opposing sides of pulley A32 and pulley B33 can be mutually restrained with the two side surfaces of slide rail 23 to prevent slide rail 23 from jumping out of the sliding space. Spring 35 can press swinging member 31 against slide rail 23. At the same time, due to the restoring force of spring 35, swinging member 31 can drive swinging block 27 to swing under the action of the restoring force. Contact ball 36 creates point contact between swinging member 31 and limiting groove 28. This point contact increases the swing frequency of swinging block 27, and thus increases the swing frequency of flexible filter screen 5, thereby reducing the passage time of solid materials through flexible filter screen 5 and improving material passage efficiency.

[0035] like Figure 6 As shown, the flexible filter screen 5 has a wavy structure and is provided with a plurality of filter holes 37. The wavy structure can mitigate the impact of materials on the flexible filter screen 5, preventing the materials from splashing due to the swinging of the flexible filter screen 5, thereby reducing the generation of solid dust. The filter holes 37 are designed to allow solid materials to pass through smoothly.

[0036] One end of the stirring rod 7 is connected to a third drive motor 38, which is fixedly connected to the outer wall of the mixing device 3. A plurality of contact blocks 39 are provided along the axial direction of the stirring rod 7, and the plurality of contact blocks 39 are cross-distributed on both sides of the stirring rod 7. By energizing the third drive motor 38, the stirring rod 7 is operated, thereby mixing the liquid material with the solid material. At the same time, the plurality of contact blocks 39 staggered on the stirring rod 7 ensure that the solid material and the liquid material are fully mixed, thereby increasing the mixing efficiency between the materials.

[0037] Example 2

[0038] On the basis of Example 1, a production device for pre-dispersed masterbatch that can improve production efficiency further includes a transverse reciprocating motion device 40 fixedly connected to the pump body 9, a discharge nozzle 10 is laterally slidably connected to the transverse reciprocating motion device 40, a hose 41 is provided between the discharge nozzle 10 and the pump body 9, and a valve body 42 is provided on the hose 41. The transverse reciprocating motion device 40 can drive the discharge nozzle 10 to reciprocate laterally, so that the discharge nozzle 10 discharges material evenly and prevents the mixture from accumulating at the discharge port. The discharge nozzle 10 and the pump body 9 are softly connected by the hose 41, so that the reciprocating motion of the discharge nozzle 10 is not affected by the position of the pump body 9.

[0039] The transverse reciprocating motion device 40 includes a hollow housing, in which a fourth drive motor 43 is disposed. A turntable 44 is fixedly connected to the output shaft of the fourth drive motor 43. A protrusion 45 is provided on the turntable 44 at a position away from the center of the circle. A connecting rod 46 is hingedly connected to the protrusion 45. A slider 47 is provided at one end of the connecting rod 46. The slider 47 is fixedly connected to the outer wall of the discharge nozzle 10. A transverse sliding rail 48 is provided in the housing, and the slider 47 is placed in the transverse sliding rail 48. One of the motion principles of the transverse reciprocating motion device 40 is the crank slider 47 mechanism principle. In particular, the fourth drive motor 43, the turntable 44, the eccentric protrusion 45, the connecting rod 46, and the slider 47 constitute the crank slider 47 mechanism. The slider 47 moves back and forth in the transverse sliding rail 48, thereby causing the slider 47 to drive the discharge nozzle 10 to reciprocate on the transverse sliding rail 48. The crank slider 47 mechanism has a simple structure, uses fewer mechanical components to achieve the purpose of reciprocating motion, and prevents material accumulation at the discharge port.

[0040] The first drive motor 6, the second drive motor 13, the third drive motor 38, and the fourth drive motor 43 are all connected to an external power supply and a switch and are independently arranged. Since the connection method between the motor, the power supply, and the switch is all existing technology, the above embodiments are all specific descriptions. When the production equipment needs to be operated, the staff can turn on the first drive motor 6, the second drive motor 13, the third drive motor 38, and the fourth drive motor 43 at the same time, and run them at no load for a period of time without the entry of materials to ensure that the mechanical components will not be stuck due to the instantaneous entry of materials.
