Raw material mixing device and raw material mixing method in production of water supply CIPP hose

Abstract

This invention discloses a raw material mixing device and a raw material mixing method in the production of CIPP hoses for water supply, relating to the field of mixing equipment. The invention uses a planetary drive assembly to drive a stirring assembly, enabling the stirring assembly to rotate and simultaneously perform circumferential motion, thereby increasing the stirring range and preventing laminar flow and dead zones during stirring, thus improving the mixing effect of the raw materials. A shearing assembly is also included, which can shear and break up agglomerated particles in the raw materials during rotation, further enhancing the mixing effect. When auxiliary materials required for mixing are fed through the inlet, they first fall onto a discharge plate, which rotates under the drive of the stirring and shearing assemblies. This causes the discharge plate to move synchronously with the auxiliary materials, uniformly discharging them circumferentially into the mixing tank during the movement, ensuring even distribution of the auxiliary materials within the mixing tank.

Description

Technical Field

[0001] This invention belongs to the field of mixing equipment, and more specifically, it relates to a raw material mixing equipment and a raw material mixing method in the production of CIPP hoses for water supply. Background Technology

[0002] Raw material mixing technology is a common production and processing technology widely used in the manufacturing field. It can control the precise proportion of different raw materials and use equipment to stir and mix them to ensure uniform distribution, thereby obtaining new products that meet the requirements.

[0003] Chinese patent CN116688808B discloses a raw material mixing device, the structure of which includes: a mixing tank body, a mixing mechanism provided inside the mixing tank body, the mixing mechanism including a mixing shaft with both ends passing through and rotatably connected to the top and bottom of the mixing tank body, and a plurality of rotatable mixing blades distributed at equal intervals on both sides of the mixing shaft.

[0004] Most existing raw material mixing equipment is consistent with the aforementioned patent, using a mixing shaft and mixing blades for rotational mixing. However, this process easily creates laminar flow and dead zones, thus reducing the mixing effect. Furthermore, during raw material mixing, it is often necessary to gradually add auxiliary materials while mixing. However, existing technologies typically use fixed feeding ports for adding auxiliary materials, causing them to accumulate in one place within the mixing equipment. This hinders the dispersion and mixing of the materials, further reducing the mixing effect. Summary of the Invention

[0006] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution:

[0009] Furthermore, both sides of the slide are provided with lifting slide rails fixedly installed on the frame, and lifting slide blocks are slidably installed on the lifting slide rails, with the lifting slide blocks fixedly connected to the back of the lifting slide plate.

[0010] Furthermore, the stirring assembly includes a stirring shaft, which is rotatably mounted on the material discharge plate, and a stirring blade is fixedly mounted at the bottom end of the stirring shaft.

[0011] Furthermore, the shearing assembly includes a shearing shaft, which is rotatably mounted on the material discharge plate, and multiple shearing shafts and multiple stirring shafts are distributed alternately in sequence. Multiple shearing wheels are fixedly mounted at the lower end of the shearing shaft.

[0012] Furthermore, the planetary drive assembly includes a stirring motor, a positioning plate, and multiple planetary gears. The stirring motor is fixedly installed inside the top seat, and an output shaft is drivenly installed at the bottom end of the stirring motor. A drive gear is fixedly installed at the bottom end of the output shaft. The positioning plate is fixedly installed on the inner wall of the top seat, and the positioning plate is located on the outer ring of the driving gear. A planetary gear ring is fixedly installed on the inner ring of the positioning plate. Multiple planetary gears are circumferentially distributed and meshed between the driving gear and the planetary gear ring. The multiple planetary gears are respectively fixedly connected to the corresponding stirring shaft and shearing shaft.

[0013] Furthermore, an isolation sleeve is fixedly installed on the inner ring of the top surface of the material discharge plate. The isolation sleeve isolates the outer ring of the top surface of the material discharge plate to form a material discharge cavity. The bottom surface of the material discharge cavity is provided with a plurality of circumferentially distributed material discharge ports. A material discharge hopper is fixedly installed at the bottom end of the material discharge port. A material discharge pipe is connected to the bottom end of the material discharge hopper. The hopper is equipped with a discharge drive shaft that extends into the discharge pipe. A feeding auger is fixedly installed at the lower end of the discharge drive shaft. A rotary drive assembly that can drive the discharge drive shaft to rotate is fixedly installed on the top surface of the discharge plate.

[0014] Furthermore, the rotary drive assembly includes a mounting box and a transmission gear ring. The mounting box is fixedly mounted on the outer ring of the top surface of the material dropping disc. One end of the mounting box is rotatably connected to the upper end of the material dropping drive shaft, and the other end of the mounting box is rotatably mounted with a transmission shaft. Synchronous pulleys are fixedly mounted on both the transmission shaft and the material dropping drive shaft. The two synchronous pulleys are connected by a synchronous belt. A transmission gear is also mounted on the transmission shaft. The transmission gear ring is fixedly mounted on the inner wall of the top seat, and the transmission gear ring and the transmission gear are meshed and connected.

[0015] Furthermore, a baffle rod is rotatably mounted on the inner wall of the top seat via a spring hinge shaft. The baffle rod is slidably disposed on the top surface of the outer ring of the material drop plate, and one end of the baffle rod abuts against the outer wall of the isolation sleeve under the torsional elastic force of the spring hinge shaft.

[0016] This invention also discloses a method for mixing raw materials in the production of CIPP hoses for water supply, the specific steps of which are as follows: The mixing tank containing the resin raw materials is placed on the lifting mechanism, and then the mixing tank is driven to rise by the lifting mechanism so that the opening at the top of the mixing tank is aligned with the bottom of the top seat. At this time, both the stirring component and the shearing component extend into the mixing tank. Then, the planetary drive component drives the stirring component and the shearing component to make circular motion in the mixing tank and rotate synchronously. The stirring component is used to stir and mix the raw materials during rotation, and the shearing component can shear and break up the agglomerated particles in the raw materials during rotation. While the mixing and shearing are in progress, the auxiliary materials are fed onto the discharge plate through the feed inlet. The discharge plate rotates under the drive of the mixing and shearing components, so that the auxiliary materials on the discharge plate move synchronously. During the movement, the auxiliary materials are fed into the mixing tank at a uniform speed along the circumference. Through the rotation of the mixing component and the rotation of the shearing component, the auxiliary materials and resin raw materials are fully and evenly mixed.

[0017] The present invention has the following beneficial effects: 1. In this invention, a planetary drive component drives the stirring component, which makes the stirring component rotate and stir simultaneously in a circular motion, thereby increasing the stirring range of the stirring component, preventing the formation of laminar flow and stirring dead zones during the stirring process, and improving the stirring and mixing effect of the raw materials. At the same time, a shearing component is also provided, which can shear and break up the agglomerated particles in the raw materials during rotation, so as to further improve the stirring and mixing effect of the raw materials.

[0018] 2. In this invention, when the auxiliary materials required for mixing the raw materials are fed through the feed inlet, the auxiliary materials first fall onto the discharge plate. The discharge plate can rotate under the drive of the stirring component and the shearing component, so that the discharge plate drives the auxiliary materials on it to move synchronously. During the movement, the auxiliary materials are uniformly discharged and transported into the mixing tank along the circumferential direction, so that the auxiliary materials are evenly distributed in the mixing tank, and the auxiliary materials can be mixed with the main materials more quickly and evenly, thereby improving the mixing efficiency of the raw materials.

[0019] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0023] The technical solutions of the embodiments of the invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the invention, and not all embodiments. Based on the embodiments of the invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the invention.

[0024] In the description of this invention, it should be understood that the terms "opening", "upper", "lower", "top", "middle", "inner", etc., which indicate orientation or positional relationship, are only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the invention.

[0025] Example 1 Please see Figures 1-4 As shown, the present invention is a raw material mixing device, including a frame 1 and a mixing tank 3. A stirring mechanism 4 is installed at the top of the frame 1, and a lifting mechanism 2 located below the stirring mechanism 4 is installed at the bottom of the frame 1. The lifting mechanism 2 can drive the mixing tank 3 to move up and down below the stirring mechanism 4. The stirring mechanism 4 includes a top seat 41, and a planetary drive assembly is installed inside the top seat 41. Multiple stirring components and multiple shearing components are installed at the bottom of the top seat 41. The planetary drive assembly can drive the multiple stirring components and multiple shearing components to rotate synchronously during the circular motion. A feeding mechanism 5 is also installed on the top seat 41. The feeding mechanism 5 includes a feed inlet 51 and a discharge plate 52. The feed inlet 51 is installed on the outer wall of the top seat 41, and the discharge plate 52 is rotatably installed inside the top seat 41 and located below the feed inlet 51. When the stirring components and shearing components are in circular motion, they can drive the discharge plate 52 to rotate synchronously, so that the discharge plate 52 discharges material at a uniform speed along the circumferential direction. Specifically, when the raw material mixing equipment of this embodiment is working, the mixing tank 3 containing the main material is first placed on the lifting mechanism 2, and then the lifting mechanism 2 drives the mixing tank 3 to rise, so that the opening at the top of the mixing tank 3 is connected to the bottom of the top seat 41. At this time, the stirring component and the shearing component extend into the mixing tank 3. Then, the planetary drive component drives the stirring component and the shearing component to rotate in the mixing tank 3 and make a circular motion synchronously. During the rotation, the stirring component stirs and mixes the raw material, and the shearing component shears and breaks up the agglomerated particles in the raw material. At the same time as stirring and shearing, the auxiliary material is conveyed to the dropping plate 52 through the feed port 51. The dropping plate 52 can rotate under the drive of the stirring component and the shearing component, so that the dropping plate 52 drives the auxiliary material on it to move synchronously. During the movement, the auxiliary material is uniformly dropped into the mixing tank 3 along the circumferential direction. Through the rotation of the stirring component and the rotation of the shearing component, the auxiliary material and the main material are fully and evenly mixed. The mixing component is driven to rotate and simultaneously perform circular motion, thereby increasing the mixing range of the mixing component, preventing the formation of laminar flow and dead zones during the mixing process, and improving the mixing effect of the raw materials. At the same time, the shearing component cuts and breaks up the agglomerated particles in the raw materials to further improve the mixing effect. The rotation of the discharge plate 52 can evenly transport the auxiliary materials into the mixing tank 3, so that the auxiliary materials can be mixed with the main materials more quickly and evenly, thus improving the mixing efficiency of the raw materials.

[0026] Example 2 Please see Figure 1 , Figure 2 , Figure 7 , Figure 8 As shown, the difference between this embodiment and the above embodiment is that the lifting mechanism 2 includes a hydraulic lifting shaft 25 and a slide 26. The slide 26 is opened at the lower front side of the frame 1. A sliding connecting seat 27 is installed inside the slide 26. The hydraulic lifting shaft 25 is fixedly installed inside the frame 1, and the telescopic end of the hydraulic lifting shaft 25 is fixedly connected to the top surface of the sliding connecting seat 27. A lifting slide plate 23 is fixedly installed on the front side of the sliding connecting seat 27, and a support seat 24 is fixedly installed at the bottom of the front side of the lifting slide plate 23. When mixing raw materials, the mixing drum 3 containing the main material is placed on the support seat 24. Then, the sliding connecting seat 27 is driven to move upward by the hydraulic lifting shaft 25. At this time, the sliding connecting seat 27 drives the lifting slide plate 23, the support seat 24 and the mixing drum 3 to move upward synchronously until the mixing drum 3 is connected to the top seat 41.

[0027] Furthermore, both sides of the chute 26 are provided with lifting slide rails 21 fixedly installed on the frame 1. Lifting slide blocks 22 are slidably installed on the lifting slide rails 21. The lifting slide blocks 22 are fixedly connected to the back of the lifting slide plate 23. When the lifting slide plate 23 moves up and down, it drives the lifting slide blocks 22 to move up and down synchronously along the lifting slide rails 21. Through the sliding cooperation between the lifting slide blocks 22 and the lifting slide rails 21, the lifting slide plate 23 can be limited, making the lifting slide plate 23 more stable during lifting and lowering, thereby improving the stability of the mixing tank 3 during lifting and conveying.

[0028] Example 3 Please see Figures 1-4 As shown, the difference between this embodiment and the above embodiment is that the stirring assembly includes a stirring shaft 46, which is rotatably mounted on the material drop plate 52, and a stirring blade 44 is fixedly mounted on the bottom end of the stirring shaft 46; the shearing assembly includes a shearing shaft 42, which is rotatably mounted on the material drop plate 52, and multiple shearing shafts 42 and multiple stirring shafts 46 are arranged alternately in sequence, and multiple shearing wheels 43 are fixedly mounted on the lower end of the shearing shaft 42. The planetary drive assembly includes a stirring motor 45, a positioning plate 411, and multiple planetary gears 49. The stirring motor 45 is fixedly installed inside the top seat 41. An output shaft 47 is driven and installed at the bottom end of the stirring motor 45, and a drive gear 48 is fixedly installed at the bottom end of the output shaft 47. The positioning plate 411 is fixedly installed on the inner wall of the top seat 41, and the positioning plate 411 is located on the outer ring of the drive gear 48. A planetary gear ring 410 is fixedly installed on the inner ring of the positioning plate 411. Multiple planetary gears 49 are circumferentially distributed and meshed between the drive gear 48 and the planetary gear ring 410. The multiple planetary gears 49 are respectively fixedly connected to the corresponding stirring shaft 46 and shearing shaft 42. During mixing, the stirring motor 45 drives the drive gear 48 to rotate via the output shaft 47. When the drive gear 48 rotates, it drives multiple planetary gears 49 on its outer ring to rotate synchronously. When the planetary gears 49 rotate, they drive the corresponding shearing shaft 42 and stirring shaft 46 to rotate. When the stirring shaft 46 rotates, it drives the stirring blades 44 to rotate and stir in the mixing tank 3. When the shearing shaft 42 rotates, it drives the shearing wheel 43 on it to shear and crush the raw materials. At the same time, the planetary gears 49 rotate and the planetary gear ring 410 performs a circular motion under the meshing transmission, thereby driving the shearing shaft 42, stirring shaft 46, shearing wheel 43 and stirring blades 44 to perform a circular motion, so as to improve the stirring range of the stirring blades 44 and the shearing range of the shearing wheel 43, thereby improving the mixing effect of the raw materials.

[0029] Example 4 Please see Figures 1-6As shown, the difference between this embodiment and the above embodiment is that an isolation sleeve 53 is fixedly installed on the inner ring of the top surface of the discharge plate 52. The isolation sleeve 53 isolates the outer ring of the top surface of the discharge plate 52 to form a discharge cavity. The bottom surface of the discharge cavity is provided with a plurality of circumferentially distributed discharge ports 54. A discharge hopper 56 is fixedly installed at the bottom end of the discharge port 54. A discharge pipe 57 is connected to the bottom end of the discharge hopper 56. A discharge drive shaft 510 extending into the discharge pipe 57 is provided inside the discharge hopper 56. A feeding auger 58 is fixedly installed at the lower end of the discharge drive shaft 510. A rotary drive assembly that can drive the discharge drive shaft 510 to rotate is fixedly installed on the top surface of the discharge plate 52. The discharge plate 52 can limit the shearing shaft 42 and the stirring shaft 46, making their installation and operation more stable. When the shearing shaft 42 and the stirring shaft 46 make circular motion, they will drive the discharge plate 52 to rotate synchronously. At this time, the discharge plate 52 will slide and transport the auxiliary material from the feed inlet 51 to its top surface into the discharge port 54 through the centrifugal force of rotation. Then, the auxiliary material enters the discharge hopper 56 through the discharge port 54 and gathers. When the discharge plate 52 rotates, it drives the discharge hopper 56 and the auxiliary material inside it to make circular motion above the mixing tank 3. At the same time, the rotation drive assembly drives the discharge drive shaft 510 and the feeding auger 58 to rotate. When the feeding auger 58 rotates, it transports the auxiliary material in the discharge hopper 56 downward at a uniform speed through the discharge pipe 57, so that the discharge plate 52 can transport the auxiliary material into the mixing tank 3 at a uniform speed along the circumferential direction during the rotation.

[0030] Furthermore, the rotary drive assembly includes a mounting box 59 and a transmission gear ring 515. The mounting box 59 is fixedly mounted on the outer ring of the top surface of the discharge plate 52. One end of the mounting box 59 is rotatably connected to the upper end of the discharge drive shaft 510. The other end of the mounting box 59 is rotatably mounted with a transmission shaft 513. Both the transmission shaft 513 and the discharge drive shaft 510 are fixedly mounted with synchronous pulleys 511. The two synchronous pulleys 511 are connected by a synchronous belt 512. A transmission gear 514 is also mounted on the transmission shaft 513. The transmission gear ring 515 is fixedly mounted on the inner wall of the top seat 41, and the transmission gear ring 515 and the transmission gear 514 are meshed and connected. When the discharge disc 52 rotates, it drives the transmission gear 514 to move in a circular motion along the transmission gear ring 515 via the mounting box 59. At this time, the transmission gear 514 rotates synchronously under the meshing transmission of the transmission gear ring 515, thereby driving the transmission shaft 513 to rotate. When the transmission shaft 513 rotates, it drives the discharge drive shaft 510 to rotate synchronously through the transmission of the synchronous pulley 511 and the synchronous belt 512. This causes the discharge drive shaft 510 to drive the feeding auger 58 to rotate and work, conveying the auxiliary material in the discharge hopper 56 downward at a uniform speed. Through the cooperation of the transmission gear ring 515, the transmission gear 514, the transmission shaft 513, the synchronous pulley 511, and the synchronous belt 512, the feeding auger 58 can be automatically driven to rotate and feed material when the discharge disc 52 rotates, making the feeding drive of the feeding auger 58 more convenient.

[0031] Furthermore, a baffle rod 55 is rotatably mounted on the inner wall of the top seat 41 via a spring hinge shaft. The baffle rod 55 is slidably disposed on the top surface of the outer ring of the material drop plate 52, and one end of the baffle rod 55 abuts against the outer wall of the isolation sleeve 53 under the torsional elastic force of the spring hinge shaft. When the material feeding disc 52 rotates and passes the baffle bar 55, the baffle bar 55 can block the material feeding disc that has not yet been centrifugally conveyed into the material feeding hopper 56. Then, when the material feeding hopper 56 moves past the position below the baffle bar 55, the blocked material feeding disc can automatically fall into the material feeding hopper 56, thus ensuring that the material feeding disc on the top surface of the material feeding disc 52 can be conveyed into the material feeding hopper 56 and will not accumulate on the surface of the material feeding disc 52. When the material feeding drive shaft 510 moves past the baffle bar 55, the material feeding drive shaft 510 can abut and rotate the baffle bar 55 so that the baffle bar 55 can avoid the material feeding drive shaft 510. After the material feeding drive shaft 510 moves past the baffle bar 55, the baffle bar 55 rotates back to its original position under the torsional elastic force of the spring hinge shaft and continues to block and intercept the material feeding disc on the surface of the material feeding disc 52.

[0032] Example 5 This embodiment discloses a method for mixing raw materials in the production of CIPP hoses for water supply, the specific steps of which are as follows: The mixing tank 3 containing resin raw materials is placed on the lifting mechanism 2, and then the mixing tank 3 is driven to rise by the lifting mechanism 2 so that the opening at the top of the mixing tank 3 is connected with the bottom of the top seat 41, and at this time the stirring component and the shearing component are both extended into the mixing tank 3. Then, the planetary drive component drives the stirring component and the shearing component to make circular motion and rotate synchronously in the mixing tank 3. The stirring component is used to stir and mix the raw materials during rotation, and the shearing component can shear and break up the agglomerated particles in the raw materials during rotation. While stirring and shearing, auxiliary materials are fed onto the discharge plate 52 through the feed inlet 51. The discharge plate 52 can rotate under the drive of the stirring component and the shearing component, so that the auxiliary materials on the discharge plate 52 move synchronously. During the movement, the auxiliary materials are uniformly discharged into the mixing tank 3 along the circumferential direction. Through the rotation of the stirring component and the rotation of the shearing component, the auxiliary materials and resin raw materials are fully and evenly mixed.

A method for mixing raw materials in the production of CIPP hoses for water supply, using the raw material mixing equipment described in any one of claims 1-9, characterized in that, The specific steps are as follows: The mixing tank containing the resin raw materials is placed on the lifting mechanism, and then the mixing tank is driven to rise by the lifting mechanism so that the opening at the top of the mixing tank is aligned with the bottom of the top seat. At this time, both the stirring component and the shearing component extend into the mixing tank. Then, the planetary drive component drives the stirring component and the shearing component to make circular motion in the mixing tank and rotate synchronously. The stirring component is used to stir and mix the raw materials during rotation, and the shearing component can shear and break up the agglomerated particles in the raw materials during rotation. While the mixing and shearing are in progress, the auxiliary materials are fed onto the discharge plate through the feed inlet. The discharge plate rotates under the drive of the mixing and shearing components, so that the auxiliary materials on the discharge plate move synchronously. During the movement, the auxiliary materials are fed into the mixing tank at a uniform speed along the circumference. Through the rotation of the mixing component and the rotation of the shearing component, the auxiliary materials and resin raw materials are fully and evenly mixed.
