Description

Technical Field

[0001] This utility model relates to the field of grinding technology, specifically to a dry powder mortar grinding device. Background Technology

[0002] Dry-mix mortar, a new type of building material widely used in construction projects, has gained increasing application in the modern construction industry due to its advantages such as stable quality, convenient construction, and material saving. Grinding is a crucial step in the production process of dry-mix mortar, as its effectiveness directly affects the quality and performance of the mortar.

[0003] Currently, most dry mortar grinding equipment on the market uses a fixed feeding device. This type of feeding device presents several problems in actual use. First, due to differences in the characteristics of different batches of raw materials (such as particle size, moisture content, and hardness), a fixed feeding speed cannot be flexibly adjusted according to the actual conditions of the raw materials. When the raw material particles are large and hard, a fixed feeding speed may cause the grinding device to operate under overload, not only reducing grinding efficiency but also accelerating the wear of grinding components and shortening the equipment's lifespan. Conversely, when the raw material particles are small and easy to grind, a fixed feeding speed will prevent the grinding device from fully utilizing its working efficiency, resulting in energy waste and low production efficiency.

[0004] Secondly, in the production process of dry mortar, it is often necessary to produce products of different specifications and qualities according to different production needs. However, existing grinding devices with fixed feeding speeds are difficult to meet diverse production requirements. For example, when producing high-precision, high-quality dry mortar, a slower and more uniform feeding speed is required to ensure the fineness of the grinding; while when producing ordinary specifications of dry mortar, the feeding speed can be appropriately increased to improve production efficiency. However, existing devices cannot achieve this flexible adjustment, limiting the diversified production of products.

[0005] In summary, existing dry mortar grinding devices have significant shortcomings in terms of material feeding speed adjustment. There is an urgent need for a dry mortar grinding device that can conveniently, quickly, and accurately adjust the material feeding speed to meet the increasingly diversified and high-quality dry mortar production needs.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a dry mortar grinding device, comprising a base plate, a grinding box fixedly connected to the top of the base plate, a hopper fixedly connected to the top of the grinding box via a bracket, rectangular openings on both sides of the grinding box, a movable frame slidably connected inside the rectangular openings, a movable plate slidably connected inside the movable frame, the top of the movable plate fitting against the bottom of the hopper, a number of openings on the top of the movable plate, the diameter of each opening decreasing from left to right, and a fixing frame fixedly connected to the left side of the movable frame extending to the left side of the grinding box. A drive box is fixedly connected to the left side of the grinding box via a bracket. A movable block is slidably connected inside the drive box, and the bottom of the movable block is fixedly connected to a fixed frame. A threaded rod is rotatably connected inside the drive box via a bearing, and the threaded rod is threadedly connected to the movable block. A first motor is fixedly connected to the left side of the drive box, and the output end of the first motor is fixedly connected to the threaded rod. A grinding roller is rotatably connected inside the grinding box. A grinding block is fixedly connected to the right side of the inner wall of the grinding box. The grinding roller and the grinding block are used in conjunction.

[0009] In a preferred embodiment of this invention, a fourth motor is fixedly connected to the top of the hopper via a bracket, and a stirring rod is fixedly connected to the output end of the fourth motor, with the bottom of the stirring rod extending into the interior of the hopper.

[0010] As a preferred embodiment of this invention, a guide plate is fixedly connected to the left side of the inner wall of the grinding box.

[0011] As a preferred embodiment of this utility model, a collection box is slidably connected to the bottom of the inner wall of the grinding box, and the front of the collection box extends to the front of the grinding box and is fixedly connected to a handle, the surface of which is provided with anti-slip texture.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. This utility model employs a movable frame, movable plate, and multiple through-holes of different diameters, allowing for flexible adjustment of the feeding speed based on the characteristics of the raw materials and production needs. When processing raw materials with larger particles and higher hardness, a larger diameter through-hole can be selected, allowing the material to enter the grinding area more quickly, preventing the grinding device from overloading, thereby improving grinding efficiency, reducing wear on grinding components, and extending the equipment's service life. Conversely, when producing high-precision, high-quality dry mortar products, a smaller diameter through-hole can be selected to achieve a slower, more uniform feeding speed, ensuring grinding precision and meeting diverse production requirements. This adjustable feeding method allows the device to adapt to differences in raw materials from different batches, fully utilizing the grinding device's working efficiency, avoiding energy waste, and improving production efficiency. It provides a more flexible and efficient solution for dry mortar production, offering advantages such as good grinding effect and ease of use.

[0015] 2. This utility model achieves the reciprocating motion of the movable plate by setting a turntable, connecting rod, and third motor on the right side of the movable frame. This reciprocating motion allows the material to be more fully dispersed and loosened before entering the grinding zone, preventing material accumulation or clumping in the hopper, thus ensuring the uniformity and continuity of material feeding. Simultaneously, the reciprocating motion of the movable plate also has a certain cleaning effect on the bottom of the hopper, preventing material residue and further improving the stability and reliability of material feeding. Through this design, the device can better control the flow state of the material, allowing it to enter the grinding zone more smoothly, thereby improving the grinding effect and product quality. Furthermore, this simple and reliable design not only reduces the manufacturing cost and maintenance difficulty of the equipment but also improves its service life and stability, providing a more reliable guarantee for the production of dry mortar.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] like Figures 1 to 5 As shown, a dry mortar grinding device includes a base plate 1, a grinding box 2 fixedly connected to the top of the base plate 1, a hopper 3 fixedly connected to the top of the grinding box 2 via a bracket, rectangular openings 4 on both sides of the grinding box 2, a movable frame 5 slidably connected inside the rectangular openings 4, a movable plate 6 slidably connected inside the movable frame 5, the top of the movable plate 6 fitting against the bottom of the hopper 3, and a passage 7 on the top of the movable plate 6, the number of passages 7 being several, and the diameter of each passage 7 decreasing from left to right. The left side of the movable frame 5 extends to the left side of the grinding box 2 and is fixedly connected to a fixing frame 8. The left side of the grinding box 2 is connected to a bracket. A drive box 9 is fixedly connected, and a movable block 10 is slidably connected inside the drive box 9. The bottom of the movable block 10 is fixedly connected to the fixed frame 8. A threaded rod is rotatably connected inside the drive box 9 via a bearing. The threaded rod is threadedly connected to the movable block 10. A first motor 11 is fixedly connected to the left side of the drive box 9. The output end of the first motor 11 is fixedly connected to the threaded rod. A grinding roller 12 is rotatably connected inside the grinding box 2. A grinding block 13 is fixedly connected to the right side of the inner wall of the grinding box 2. The grinding roller 12 and the grinding block 13 are used in conjunction. A second motor is fixedly connected to the back of the grinding box 2. The output end of the second motor is fixedly connected to the grinding roller 12.

[0024] refer to Figure 3 An opening 14 is provided on the right side of the movable frame 5. A turntable 15 is rotatably connected inside the opening 14. A connecting rod 16 is rotatably connected to the top of the turntable 15. The end of the connecting rod 16 away from the turntable 15 is hinged to the right side of the movable plate 6. A third motor 17 is fixedly connected to the bottom of the movable frame 5. The output end of the third motor 17 is fixedly connected to the turntable 15.

[0025] As a technical optimization of this utility model, the reciprocating motion of the movable plate 6 is achieved by setting a turntable 15, a connecting rod 16, and a third motor 17 on the right side of the movable frame 5. This reciprocating motion allows the material to be more fully dispersed and loosened before entering the grinding area, preventing the material from accumulating or clumping in the hopper 3, thus ensuring the uniformity and continuity of the feeding. At the same time, the reciprocating motion of the movable plate 6 can also play a certain role in cleaning the bottom of the hopper 3, preventing material residue, and further improving the stability and reliability of the feeding. Through this design, the device can better control the flow state of the material, allowing the material to enter the grinding area more smoothly, thereby improving the grinding effect and product quality. In addition, this simple and reliable design not only reduces the manufacturing cost and maintenance difficulty of the equipment, but also improves the service life and stability of the equipment, providing a more reliable guarantee for the production of dry mortar.

[0026] refer to Figure 1 A fourth motor 24 is fixedly connected to the top of the hopper 3 via a bracket. A stirring rod 25 is fixedly connected to the output end of the fourth motor 24. The bottom of the stirring rod 25 extends into the interior of the hopper 3.

[0027] As a technical optimization of this utility model, by setting a fourth motor 24 and a stirring rod 25 above the hopper 3, the material can be fully stirred before entering the grinding area. This stirring action can fully mix materials of different components, ensuring the uniformity of the dry mortar formula, thereby improving the quality stability of the product. At the same time, the stirring of the stirring rod 25 can also break up lumps in the material, making the material particles finer and more uniform, providing better conditions for subsequent grinding processes. Through this pre-stirring treatment, the device can effectively improve grinding efficiency, reduce grinding time, and reduce energy consumption. In addition, the setting of the stirring rod 25 can also prevent material from bridging or clogging in the hopper 3, ensuring smooth material discharge, and further improving the operational stability and reliability of the equipment.

[0028] refer to Figure 2 A guide plate 18 is fixedly connected to the left side of the inner wall of the grinding box 2.

[0029] As a technical optimization of this utility model, by setting a guide plate 18 on the left side of the inner wall of the grinding chamber 2, the material can be guided accurately into the grinding area between the grinding roller 12 and the grinding block 13. This guiding effect can prevent the material from flowing randomly in the grinding chamber 2, improving the grinding efficiency and uniformity of the material. The reasonable design of the guide plate 18 can also allow the material to stay in the grinding area for a longer time, increasing the contact opportunity between the material and the grinding roller 12 and the grinding block 13, thereby improving the grinding effect. Through this design, the device can better control the grinding process of the material, making the grinding more thorough and complete, and improving the fineness and quality of the dry powder mortar. In addition, the setting of the guide plate 18 can also reduce the impact and wear of the material on the inner wall of the grinding chamber 2, extend the service life of the equipment, and reduce the maintenance cost of the equipment (the grinding roller 12 and the grinding block 13 are common existing technologies and are common knowledge to those skilled in the art, and will not be described in detail in this application).

[0030] refer to Figure 2 A collection box 19 is slidably connected to the bottom of the inner wall of the grinding box 2. The front of the collection box 19 extends to the front of the grinding box 2 and is fixedly connected to a handle. The surface of the handle is provided with anti-slip texture.

[0031] As a technical optimization of this utility model, a collection box 19 is installed at the bottom of the inner wall of the grinding chamber 2, which can be easily pulled out and pushed in via a handle, facilitating the collection and cleaning of the ground dry mortar. This design allows operators to quickly and conveniently collect finished materials, improving production efficiency. The collection box 19 also prevents the ground material from accumulating inside the grinding chamber 2, affecting the normal operation of the equipment. By cleaning the collection box 19 in a timely manner, the device can maintain good working condition, ensuring the stability and reliability of the grinding effect. In addition, the anti-slip textured design on the handle surface increases the friction for the operator's grip, making operation safer and more convenient, and reducing the occurrence of accidents during operation.

[0032] refer to Figure 4 The bottom of the grinding box 2 is fixedly connected to support columns 20 on all four sides. The support columns 20 are slidably connected to the inside of the support columns 20. The bottom of the connecting frame 21 is fixedly connected to casters 22. The top of the base plate 1 is fixedly connected to electric cylinders 23 on both sides. The output end of the electric cylinder 23 extends to the bottom of the base plate 1 and is fixedly connected to the top of the connecting frame 21.

[0033] As a technical optimization of this utility model, by setting a support column 20, a connecting frame 21, casters 22, and an electric cylinder 23 at the bottom of the grinding box 2, flexible movement and fixation of the equipment are achieved. When the equipment needs to be moved, the electric cylinder 23 drives the connecting frame 21 to descend, causing the casters 22 to contact the ground and the support column 20 to detach from the ground, at which point the equipment can be easily moved to the desired position. When the equipment reaches the designated position, the electric cylinder 23 drives the connecting frame 21 to rise, causing the support column 20 to contact the ground and the casters 22 to detach from the ground, at which point the equipment can be stably fixed to the ground. This design allows the device to adapt to different working environments and production needs, improving the flexibility and applicability of the equipment. At the same time, the inclusion of casters 22 can reduce the labor intensity during equipment movement and improve work efficiency. In addition, the driving method of the electric cylinder 23 has the characteristics of precise control and stable operation, ensuring the safety and reliability of the equipment during movement and fixation.

[0034] The working principle and usage process of this utility model are as follows: 1. Equipment preparation: Before formally putting the equipment into use, a comprehensive inspection must be carried out. Carefully check whether the grinding box 2, hopper 3, drive box 9, and other components are damaged or loose, ensuring that all components are firmly connected and free from abnormalities. Check whether the sliding and rotation of movable parts such as the movable frame 5, movable plate 6, and grinding roller 12 are smooth, avoiding any impact on equipment operation due to component jamming. At the same time, check whether the wiring of each motor, electric cylinder 23, and other electrical equipment is correct, ensuring that the equipment is powered normally and safely. All the above electrical appliances are controlled by an external controller. The wiring of the above electrical appliances and the external controller are common existing technologies and are common knowledge to those skilled in the art, and will not be described in detail in this application.

[0035] The support column 20 and casters 22 at the bottom of the grinding box 2 are controlled by the electric cylinder 23. If the equipment needs to be moved, the electric cylinder 23 is activated to drive the connecting frame 21 to descend, so that the casters 22 contact the ground and the support column 20 is lifted off the ground, thus moving the equipment smoothly to a suitable working position. If the equipment is already in the ideal position, the electric cylinder 23 drives the connecting frame 21 to rise, so that the support column 20 contacts the ground and the casters 22 are lifted off the ground, ensuring that the equipment is placed stably and preventing shaking during operation.

[0036] 2. Material handling: Pour the raw materials for the dry mortar to be ground into hopper 3. At this time, the fourth motor 24 above hopper 3 drives the stirring rod 25 to start working, thoroughly stirring the materials. During the stirring process, materials of different components are fully mixed, and lumps are broken up, ensuring that the material particles are fine and uniform, guaranteeing the uniformity of the dry mortar formula, and laying a good foundation for the subsequent grinding process.

[0037] Based on the characteristics of the raw materials, such as particle size, hardness, or production requirements, a suitable feeding method is selected. If the raw material particles are large and have high hardness, the operator starts the first motor 11 to rotate, driving the threaded rod to rotate, which in turn moves the movable block 10 and the fixed frame 8 to the right, thereby moving the movable frame 5 to the right, aligning the larger diameter opening 7 on the movable plate 6 with the bottom of the hopper 3, allowing the material to enter the grinding area more quickly. Similarly, to produce high-precision, high-quality dry mortar products, the smaller diameter opening 7 on the movable plate 6 is aligned with the bottom of the hopper 3 to achieve slow and uniform feeding. At the same time, the third motor 17 on the right side of the movable frame 5 is started, driving the turntable 15 to rotate, which, through the connecting rod 16, causes the movable plate 6 to reciprocate left and right, dispersing and loosening the material in the hopper 3, preventing material accumulation or clumping, and ensuring the uniformity and continuity of feeding.

[0038] III. Grinding Operation: After confirming the material feeding settings are complete, start the second motor on the back of the grinding chamber 2 to drive the grinding roller 12 to rotate. Simultaneously, the grinding roller 12 engages with the grinding block 13 fixed to the right side of the inner wall of the grinding chamber 2 to grind the material entering the grinding area. The guide plate 18 on the left side of the inner wall of the grinding chamber 2 guides the material accurately between the grinding roller 12 and the grinding block 13, ensuring full contact between the material and the grinding components within the grinding area, extending the residence time, and improving grinding efficiency and uniformity. During the grinding process, continuously observe the equipment operation, paying attention to any abnormal noises, vibrations, or other phenomena. If any problems are found, stop the machine immediately for inspection and handling.

[0039] IV. Finished Product Collection: The ground dry mortar will fall into the collection box 19 at the bottom of the inner wall of the grinding chamber 2. When the material in the collection box 19 reaches a certain amount, the operator holds the handle with anti-slip texture on the front of the collection box 19 and smoothly pulls the collection box 19 out of the grinding chamber 2, transferring the finished material to the designated storage location. After the material transfer is completed, the collection box 19 is pushed back into the grinding chamber 2 to ensure that the collection box 19 is installed in place so that the ground material can continue to be collected.
