Description

Technical Field

[0001] This invention relates to the field of wax powder technology, and specifically to a polyethylene wax powder mixing and stirring device and method. Background Technology

[0002] Polyethylene wax powder is a colorless powdery solid made primarily from polyethylene. It possesses excellent thermal stability, low viscosity, low-temperature performance, low smoke emission, and good lubricity. The molecular weight of polyethylene wax powder is generally low, approximately 2000-3000, and it is frequently used as an additive in industrial applications.

[0003] For example, Chinese patent CN114082328A, entitled "A Mixing and Stirring Device for Polyethylene Wax Powder," includes a stirring chamber, a support frame, and a stirring part. The stirring chamber is a cylindrical hollow cavity placed horizontally. The support frame is vertically fixed to both ends of the stirring chamber. The stirring part is disposed inside the stirring chamber. After the material enters the stirring chamber, it is stirred and mixed by the stirring part and then discharged from the outlet at the bottom of the stirring chamber. This invention has a simple structure. By placing the stirring chamber horizontally, it avoids the accumulation of mixture at the bottom of the stirring chamber. Simultaneously, the stirring part inside the stirring chamber can spirally push the material from one end to the other, greatly improving the mixing efficiency of the equipment. It also avoids material waste caused by the accumulation of mixed materials at the bottom of the equipment, thus improving work efficiency and saving costs.

[0004] Traditional methods of adding polyethylene wax powder typically involve mixing all the materials together and then stirring. For example, in the patent mentioned above, the entire mixture is injected into the mixing cavity and then stirred by the stirring unit. Since the mixture is all piled up together, it will cause the material to accumulate in one place during stirring and then disperse, thus reducing the mixing efficiency. Summary of the Invention

Detailed Implementation

[0050] To make the objectives, technical solutions, and advantages of the embodiments of this disclosure clearer, the technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this disclosure. All other embodiments obtained by those skilled in the art based on the described embodiments of this disclosure without creative effort are within the scope of protection of this disclosure.

[0051] Please see Figure 1-11 This embodiment provides a polyethylene wax powder mixing and stirring device, comprising a stirring vessel 1 and a feeding tank 2, the feeding tank 2 being interconnected with the stirring vessel 1 via a feeding pipe 21; a stirring assembly for mixing and stirring the raw materials in the stirring vessel 1, the stirring assembly including a stirring rod 31 rotating within the stirring vessel 1, the stirring rod 31 extending into the stirring vessel 1 and fixedly connected to multiple stirring blades 32; a drive assembly and a switching transmission mechanism, the drive assembly being driven to slowly rotate the stirring assembly via the switching transmission mechanism, and the switching transmission mechanism being driven to rotate the feeding tank 2; when the feeding tank 2 is fully fed, the passive drive switching transmission mechanism is separated and drives the drive assembly to drive the stirring assembly to quickly stir, thereby stirring the various raw materials in the stirring vessel 1 through the stirring assembly, and then injecting the polyethylene wax powder from the feeding tank 2 into the stirring vessel 1 through the feeding pipe 21; then, the speed regulating assembly first rotates the raw materials in the stirring vessel 1 at a low speed to generate a vortex for easy dispersion, and then after the polyethylene wax powder is completely added, it is stirred at a high speed, thereby making the raw materials completely dispersed and uniformly mixed, which is convenient to operate and improves the mixing efficiency.

[0052] In a further embodiment of the present invention, the driving component includes an F-shaped support plate 11, a rotating tube 42 is rotatably connected to the upper surface of the F-shaped support plate 11, the output end of a motor 41 is fixedly connected to the top end of the rotating tube 42, a non-shaped rod 43 is slidably arranged inside the rotating tube 42, and a limiting groove 44 adapted to the non-shaped rod 43 is provided on the stirring rod 31.

[0053] Furthermore, the switching transmission mechanism also includes a guide block 471 that slides inside the mixing vessel 1. A rotating rod 47 is rotatably connected to the guide block 471. A second gear 48 and a second pulley 49 are fixedly connected to the outside of the rotating rod 47. A first pulley 45 is slidably sleeved on the outside of the shaped rod 43. A first gear 33 is fixedly connected to the outside of the stirring rod 31. The first gear 33 and the second gear 48 mesh with each other. It also includes a belt 46, which is driven to mesh with the first pulley 45 and the second pulley 49. When the motor 41 starts, it drives the rotating tube 42 to rotate, thereby causing the shaped rod 43 to rotate synchronously, which in turn drives the first pulley 45 to rotate synchronously. The belt 46 drives the second pulley 49 to rotate synchronously, which in turn causes the rotating rod 47 to rotate synchronously, which in turn drives the second gear 48 to rotate, which in turn drives the first gear 33 to rotate, which in turn drives the stirring rod 31 to rotate. This causes multiple stirring blades 32 to rotate synchronously, stirring the raw materials in the mixing vessel 1 at low speed and generating vortices.

[0054] Furthermore, it also includes a limiting component, which is used to keep the drive component and the switching transmission mechanism in constant transmission engagement. The limiting component includes a guide plate 101 fixed to the outside of the mixing vessel 1, a guide rod 102 slidably disposed inside the guide plate 101, a fixing plate 103 fixedly connected to one end of the guide rod 102, and a snap-fit ​​plate 105 fixedly connected to the other end of the guide rod 102. A tension pulley 104 is rotatably connected inside the fixing plate 103, and the tension pulley 104 is in transmission engagement with the belt 46. The outer sleeve is equipped with a return spring 106. After the rotating rod 47 moves, the second pulley 49 moves, which stretches the tension belt 46, thereby causing the tension pulley 104 to move. This drives the fixed plate 103 to move synchronously, which causes the guide rod 102 to slide within the guide plate 101, compressing the return spring 106. This ensures that the belt 46 is always engaged with the first pulley 45 and the second pulley 49. When the first pulley 45 rotates, the second pulley 49 rotates synchronously through the belt 46.

[0055] In a further embodiment of the present invention, a control component is also provided. The control component includes a guide tube 56 that rotates outside the feed hopper 2. A rectangular rod 57 is slidably disposed inside the guide tube 56. An active ratchet disc 58 is fixedly connected to the end of the rectangular rod 57. A compression spring 59 is sleeved on the rectangular rod 57.

[0056] It also includes a second support plate 12 fixed on the mixing vessel 1. A sliding tube 51 is rotatably connected inside the second support plate 12. A screw 53 is threadedly connected inside the sliding tube 51. A driven ratchet 55 adapted to the active ratchet 58 is fixedly connected to the end of the sliding tube 51. A limit tube 54 is rotatably connected to the end of the screw 53. The limit tube 54 is rotatably connected to the rotating rod 47.

[0057] In the embodiment provided by the present invention, a support rod 9 is fixedly connected to the outside of the limiting tube 54, and a locking block 91 is fixedly connected to the end of the support rod 9. The locking block 91 is located in contact with the shaped rod 43 and the stirring rod 31. A limiting groove 44 adapted to the shaped rod 43 is opened in the stirring rod 31. When the first gear 33 moves out of the third gear 67, the third gear 67 is driven to rotate counterclockwise by the elastic release of the torsion spring 52, thereby driving the guide tube 56 to rotate counterclockwise. The rectangular rod 57 drives the active ratchet 58 to rotate counterclockwise synchronously. Since the contact surface between the active ratchet 58 and the driven ratchet 55 is flat when the active ratchet 58 rotates counterclockwise, it is compressed by the compression spring 59. The active ratchet 58 drives the driven ratchet 55 to rotate synchronously, thereby causing the sliding tube 51 to rotate and the screw 53 to slide into the sliding tube 51. This causes the rotating rod 47 to move synchronously through the limiting tube 54, thereby causing the second gear 48 to move out of the first gear 33. At the same time, the movement of the limiting tube 54 causes the support rod 9 to move synchronously, thereby causing the locking block 91 to move out of the stirring rod 31. The irregular rod 43 descends due to gravity, thereby causing the irregular rod 43 to insert into the limiting groove 44. This allows the irregular rod 43 to directly drive the stirring rod 31 to rotate, thereby increasing the rotation speed of the stirring rod 31 and ensuring that the stirring blade 32 fully mixes the raw materials and polyethylene wax powder.

[0058] Specifically, the control assembly also includes a receiving plate 61 that slides inside the feeding hopper 2. A connecting rod 63 is fixedly connected to the bottom end of the receiving plate 61, and a connecting plate 64 is fixedly connected to the bottom end of the connecting rod 63. A first rack 66 is fixedly connected to the connecting plate 64, and the first rack 66 meshes with a third gear 67. A torsion spring 52 is sleeved on the guide rod 102. The two ends of the torsion spring 52 are fixedly connected to the third gear 67 and the feeding hopper 2, respectively. When the polyethylene wax powder in the feeding hopper 2 decreases, the elasticity of the support spring 65 drives the connecting rod 63 to move upward, thereby causing the receiving plate 61 to move upward, which in turn causes the telescopic tube 62 to stretch, causing the connecting plate 64 to move synchronously, which in turn causes the first rack 66 to move upward. When the first rack 66 moves to the third gear 67, the upward movement of the first gear 63 will cause the third gear 67 to rotate clockwise, thereby causing the guide tube 56 to rotate synchronously, which in turn causes the torsion spring 52 to twist, thus storing force in the torsion spring 52.

[0059] In a further embodiment of the present invention, the bottom of the receiving plate 61 is connected to a telescopic tube 62, which is connected to the outlet of the receiving bucket. A support spring 65 is sleeved on the connecting rod 63. The two ends of the support spring 65 are fixedly connected to the feeding bucket 2 and the connecting plate 64, respectively. When the polyethylene wax powder on the receiving plate 61 decreases, the elasticity of the support spring 65 drives the receiving bucket to move upward, thereby lengthening the telescopic tube 62 and facilitating the movement of the first rack 66.

[0060] In this invention, a sealing plate 7 is slidably disposed within the mixing vessel 1. The sealing plate 7 reciprocates via a rotating assembly to switch the opening and closing states of the feed hopper 2. The rotating assembly includes a sliding rod 81 fixed to the sealing plate 7. The top end of the sliding rod 81 extends outside the mixing vessel 1 and is fixedly connected to a limiting plate 82. A second rack 83 is fixedly connected to the limiting plate 82. A drive rod 86 is rotatably connected within the second support plate 12. A sector gear 84 and a driven bevel gear 87 are fixedly connected to both ends of the drive rod 86, respectively. The sector gear 84 and the second rack 83 mesh with each other. An active bevel gear 88 that meshes with the driven bevel gear 87 is fixedly connected to the outside of the rotating rod 47. A contact spring 85 is sleeved on the sliding rod 81. Both ends of the contact spring 85 are fixedly connected to the mixing vessel 1 and the limiting plate 82, respectively. The polyethylene raw material in the feed hopper 2 is fed through the receiving end. The cavity in plate 61 leads into the telescopic tube 62, and then into the mixing vessel 1 through the feed pipe 21. When the rotating rod 47 rotates, it drives the driving bevel gear 88 to rotate, which in turn drives the driven bevel gear 87 to rotate. The drive rod 86 drives the sector gear 84 to rotate synchronously. When the teeth of the sector gear 84 contact the second rack 83, it drives the second rack 83 to move upward, which causes the limiting plate 82 to move synchronously. The sliding rod 81 drives the sealing plate 7 to move upward synchronously, which compresses the abutment spring 85. When the sealing plate 7 moves upward, the polyethylene wax powder in the feed pipe 21 enters the mixing vessel 1. When the teeth of the sector gear 84 move out of the second rack 83, the elastic release of the abutment spring 85 causes the sliding rod 81 to move downward, which seals the feed pipe 21 with the sealing plate 7, allowing the polyethylene wax powder to be injected into the mixing vessel 1 in small amounts multiple times.

[0061] Furthermore, the mixing method of the polyethylene wax powder mixing and stirring device includes the following steps:

[0062] S1: Pour multiple raw materials into the mixing tank 1, and at the same time pour the proportioned polyethylene wax powder into the feed tank 2. Drive the sealing plate 7 to reciprocate through the rotating component, so that the polyethylene wax powder is fed into the mixing tank 1 in small amounts and multiple times.

[0063] S2: The drive component drives the switching transmission mechanism to rotate, which in turn drives the stirring component to rotate, thereby mixing the raw materials and polyethylene wax powder in the stirring tank 1 at a low speed.

[0064] S3: The driving component drives the stirring component to move, thereby making the stirring component rotate at high speed to achieve complete dispersion and uniform mixing.

[0065] When stirring the polyethylene wax powder, first pour the other raw materials into the mixing tank 1, then pour the polyethylene wax powder into the feed tank 2, and start the motor 41 to drive the rotating tube 42 to rotate (to... Figure 2Based on the reference, the shaped rod 43 rotates synchronously, thereby driving the first pulley 45 to rotate synchronously, and through the belt 46 driving the second pulley 49 to rotate synchronously, thereby driving the rotating rod 47 to rotate synchronously, driving the second gear 48 to rotate, thereby driving the first gear 33 to rotate, thereby driving the stirring rod 31 to rotate, so that multiple stirring blades 32 rotate synchronously, stirring the raw materials in the stirring vessel 1 at low speed and generating vortices;

[0066] The polyethylene raw material in the feed hopper 2 enters the telescopic pipe 62 through the hole in the receiving plate 61, and then enters the mixing vessel 1 through the feed pipe 21. When the rotating rod 47 rotates, it drives the driving bevel gear 88 to rotate (to... Figure 5 Based on the reference, the driven bevel gear 87 rotates, and the drive rod 86 drives the sector gear 84 to rotate synchronously. When the teeth of the sector gear 84 contact the second rack 83, the second rack 83 moves upward, thereby causing the limiting plate 82 to move synchronously. The sliding rod 81 drives the sealing plate 7 to move upward synchronously, thereby compressing the abutment spring 85. When the sealing plate 7 moves upward, the polyethylene wax powder in the feed pipe 21 enters the mixing tank 1. When the teeth of the sector gear 84 move out of the second rack 83, the elastic release of the abutment spring 85 causes the sliding rod 81 to move downward, so that the sealing plate 7 seals the feed pipe 21, thereby allowing the polyethylene wax powder to be injected into the mixing tank 1 in small amounts and multiple times.

[0067] When the amount of polyethylene wax powder in the feed hopper 2 decreases, the elasticity of the support spring 65 causes the connecting rod 63 to move upward (to... Figure 4 (Based on), thus causing the receiving plate 61 to move upward, driving the telescopic tube 62 to stretch, causing the connecting plate 64 to move synchronously, driving the first rack 66 to move upward, and when the first rack 66 moves to the third gear 67 (based on), the receiving plate 61 moves ... Figure 7 (Based on the first gear 33), the upward movement of the first gear 33 will drive the third gear 67 to rotate clockwise, thereby driving the guide tube 56 to rotate synchronously, which will cause the torsion spring 52 to twist. At the same time, the rotation of the guide tube 56 will drive the rectangular rod 57 to rotate synchronously, which will cause the active ratchet 58 to rotate synchronously. Since the contact surface between the active ratchet 58 and the driven ratchet 55 is an inclined surface when the active ratchet 58 rotates clockwise, when the active ratchet 58 rotates clockwise, it will drive the active ratchet 58 to move inward into the guide rod 102, thereby compressing the compression spring 59.

[0068] When the first gear 33 moves out of the third gear 67, the elastic release of the torsion spring 52 causes the third gear 67 to rotate counterclockwise, which in turn causes the guide tube 56 to rotate counterclockwise. This, in turn, causes the active ratchet 58 to rotate counterclockwise synchronously via the rectangular rod 57. Since the contact surface between the active ratchet 58 and the driven ratchet 55 is flat when the active ratchet 58 rotates counterclockwise, the compression spring 59 causes the active ratchet 58 to drive the driven ratchet 55 to rotate synchronously, thus causing the sliding tube 51 to rotate and driving the screw 53 to move into the sliding tube 51. The sliding mechanism drives the rotating rod 47 to move synchronously through the limiting tube 54, thereby causing the second gear 48 to move out of the first gear 33. At the same time, the movement of the limiting tube 54 drives the support rod 9 to move synchronously, thereby causing the locking block 91 to move out of the stirring rod 31. The irregular rod 43 descends due to gravity, thereby causing the irregular rod 43 to insert into the limiting groove 44. This allows the irregular rod 43 to directly drive the stirring rod 31 to rotate synchronously, thereby improving the rotation efficiency of the stirring rod 31 and ensuring that the stirring blade 32 fully mixes the raw materials and polyethylene wax powder.

[0069] When the rotating rod 47 drives the second pulley 49 to move, the tension belt 46 is stretched, which causes the tension pulley 104 to move, driving the fixed plate 103 to move synchronously, which causes the guide rod 102 to slide in the guide plate 101, causing the return spring 106 to be compressed, thereby ensuring that the belt 46 is always engaged with the first pulley 45 and the second pulley 49.

[0070] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
