Description

Technical Field

[0001] This utility model relates to the field of laundry detergent production technology, and in particular to a laundry detergent mixing device. Background Technology

[0002] In the laundry detergent production industry, the performance of mixing equipment is crucial to product quality and production efficiency. Current technology often uses large agitators to mix powdered raw materials in laundry detergent mixing equipment. However, this method has significant drawbacks: because laundry detergent is a powdery solid, the large contact area between the material and the agitator during mixing leads to a significant increase in mixing resistance. This not only increases energy consumption but also shortens equipment lifespan due to high-load operation. Furthermore, driving large agitators requires a high-powered power system, further increasing manufacturing costs and operating energy consumption. Moreover, mixing efficiency is limited by the poor flowability of the powder, making it difficult to achieve uniform mixing of raw materials and effective crushing of crystalline particles.

[0003] In addition, traditional equipment generally suffers from the following shortcomings: a single stirring structure cannot simultaneously handle raw material mixing and crystalline particle crushing, easily leading to large particle impurities in the finished product; it lacks a fine screening and secondary grinding mechanism, making it difficult to control the uniformity of raw material particle size; and the power system often adopts an independent drive mode, resulting in a complex structure and high maintenance costs. To address these problems, this invention provides a mixing device that integrates grinding, screening, and secondary grinding. It replaces traditional stirring with the pressing action of rollers and grinding discs, reducing powder resistance and energy consumption. Simultaneously, the synergistic effect of moving and stationary screens achieves fine particle processing, effectively improving production efficiency and finished product quality.

Unless otherwise stated, they are assumed to be used and equipped with existing technology and no special explanation is required.

[0023] It should be noted that, in order to make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0024] Depend on Figure 1-4 The washing powder mixing device shown includes a mixing cylinder 1, the bottom of which is used to discharge the crushed and mixed washing powder; the top of the mixing cylinder 1 is open and connected to an external feeding device; a mixing unit is provided at the top of the inner cavity of the mixing cylinder 1, the mixing unit includes a grinding disc 2, a driving component is passed through the center of the grinding disc 2, the top of the driving component is fixedly connected to the mixing cylinder 1, the bottom of the driving component passes through the grinding disc 2 and is driven to a moving screen, the moving screen is slidably connected to a stationary screen 10; the stationary screen 10 is fixedly connected to the inner wall of the mixing cylinder 1; a guide cylinder 3 is provided between the moving screen and the grinding disc 2; a fixing ring is sleeved on the outer side of the grinding disc 2, a connecting block is fixedly connected to the inner wall of the fixing ring, and the fixing ring is fixedly connected to the grinding disc 2 through the connecting block; a grinding roller is driven to the driving component, the grinding roller is adapted to the grinding disc 2 and is slidably connected.

[0025] Furthermore, the side wall of the mixing cylinder 1 is provided with an operating window for easy maintenance of the moving and stationary screens 10. It also allows for the transfer of insufficiently ground laundry detergent raw materials to the grinding disc 2 for re-grinding and crushing. This is existing technology and will not be elaborated further here.

[0026] Furthermore, the opening at the top of the mixing cylinder 1 is used to receive external conveying devices for laundry detergent raw materials, including but not limited to augers or conveyor belts, which directly feed the raw materials onto the grinding disc 2 for direct grinding.

[0027] The scheme is further optimized. The drive component includes a motor 4, which is fixedly connected to the side wall of the mixing cylinder 1. The motor 4 is driven by a rotating shaft 5. The top of the rotating shaft 5 is driven by a grinding roller. The bottom of the rotating shaft 5 is fixedly connected to a protrusion 6 that drives the moving screen. The rotating shaft 5 is driven by the moving screen through the protrusion 6. The protrusion 6 drives the drive ring 8 to move eccentrically, thereby realizing the relative sliding between the screen body 7 and the stationary screen 10.

[0028] Furthermore, the motor 4 integrates a reducer, which can increase the torque of the rotating shaft 5 and improve the driving force during the grinding process.

[0029] Further optimizing the design, the moving screen includes a screen body 7 with a mounting hole at its center. A drive ring 8 is fixedly connected to the mounting hole, and retaining rings 9 are fixedly connected to the periphery of the screen body 7. A gap is provided between the retaining rings 9 and the inner wall of the mixing cylinder 1. The inner wall of the drive ring 8 is connected to the protrusion 6. The screen body 7 slides in contact with the stationary screen 10. A flexible dust cover 17 is fixedly connected to the top surface of the drive ring 8, and a rotating shaft 5 passes through and is rotatably connected to the dust cover 17. The dust cover 17 prevents the detergent material falling from the grinding disc 2 from entering the drive ring 8, thus affecting the operation of the moving screen. The dust cover 17 is preferably made of rubber or silicone and is bonded to the drive ring 8 with adhesive. The top of the dust cover 17 is rotatably connected to the rotating shaft 5 using a sealed bearing.

[0030] Furthermore, the mesh size of the static screen 10 is matched with the particle size of the final laundry detergent product. The mesh size of the screen body 7 is smaller than that of the static screen 10, which allows large particles of laundry detergent raw material to pass through, and further grinding and crushing can be achieved through the relative movement of the screen body 7 and the static screen 10.

[0031] Further optimization of the design: a grinding groove 11 is provided on the top surface of the grinding disc 2 along the periphery. The grinding groove 11 is adapted to and slidably connected to the grinding roller. A through hole is provided in the center of the grinding disc 2, and the middle part of the grinding disc 2 is higher than the edge, so that the introduced laundry detergent raw material can be continuously introduced into the grinding groove 11.

[0032] Further optimization of the design: the roller includes an arc-shaped mounting block 12, with several grinding balls 13 rotatably connected to the bottom surface of the mounting block 12. The grinding balls 13 are adapted to and slide in contact with the grinding trough 11. Two elastic connecting rods 14 are symmetrically fixedly connected to the side of the rotating shaft 5. One end of one connecting rod 14 is fixedly connected to the side of the mounting block 12, and one end of the other connecting rod 14 is fixedly connected to a material shovel, which is adapted to and slides in contact with the grinding trough 11. The bottom of the grinding trough 11 is a semi-circular arc-shaped groove, which can be adapted to the grinding balls 13. Through the crushing of the grinding balls 13, the washing powder raw materials are mixed, and large crystalline particles are crushed.

[0033] Furthermore, the connecting rod 14 is an elastic rod, which enables the grinding ball 13 to bypass particles that are difficult to grind and crush through the elastic deformation of the connecting rod 14, thereby avoiding hindering the processing efficiency of the grinding ball 13.

[0034] The design is further optimized so that the shovel includes a shovel block 15 and a guide block 16. One side of the guide block 16 is fixedly connected to another connecting rod 14, and the other side of the guide block 16 is fixedly connected to the shovel block 15. The bottom ends of the shovel block 15 and the guide block 16 are respectively adapted to and slidably connected to the grinding groove 11. The end of the shovel block 15 away from the guide block 16 has a wedge-shaped structure. The end of the guide block 16 near the shovel block 15 has an inclined surface, and the side of the guide block 16 near the edge of the grinding disc 2 has a bevel. The top surface of the guide block 16 is higher than the edge of the grinding disc 2. The top of the shovel block 15 is not higher than the edge of the grinding disc 2. The ground laundry detergent raw material is scooped up by the shovel block 15 and gradually pushed to the guide block 16 by the inclined surface of the shovel block 15. The gradually accumulated laundry detergent raw material is pushed to the gap between the grinding disc 2 and the inner wall of the mixing cylinder 1 by the blocking on the other side of the opening of the guide block 16, and then further falls into the moving screen through the guide cylinder 3.

[0035] Further optimization of the design: the guide cylinder 3 is a ring-shaped funnel structure, with the bottom opening of the guide cylinder 3 sleeved on the outside of the rotating shaft 5 and connected to the mesh body 7.

[0036] The working process of this embodiment is as follows:

[0037] When the laundry detergent mixing equipment is working, an external conveying device (such as an auger or conveyor belt) transports the laundry detergent raw materials from the top opening of the mixing cylinder 1 to the top surface of the grinding disc 2. The motor 4 drives the rotating shaft 5 to rotate, causing the grinding rollers to roll in the grinding groove 11 of the grinding disc 2. The grinding balls 13 cooperate with the semi-circular arc-shaped grinding groove 11 to crush the raw materials, achieving mixing and crystalline particle crushing. The design of the middle of the grinding disc 2 being higher than the edge causes the raw materials to converge towards the grinding groove 11. At the same time, the elastic connecting rod 14 drives the material shovel to rotate synchronously. The shovel block 15 scoops up the raw materials in the grinding groove 11 and pushes them to the edge of the grinding disc 2 through the inclined surface and bevel of the guide block 16, and then falls into the moving screen through the guide cylinder 3.

[0038] Driven by the protrusion 6 at the bottom of the rotating shaft 5, the moving screen 7 slides relative to the stationary screen 10 via the driving ring 8. The mesh size of the moving screen 7 is smaller than that of the stationary screen 10, causing large particles to be trapped and subjected to secondary grinding through friction. Qualified particles fall through the stationary screen 10 and are discharged from the bottom of the mixing cylinder 1. The dust cover 17 prevents raw materials from entering the driving ring 8, ensuring stable operation of the moving screen. This process, through a cyclical mechanism of "grinding-screening-secondary grinding," achieves efficient mixing and particle refinement of laundry detergent raw materials, improving the quality of the finished product.

[0039] The above are merely preferred embodiments of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
