TECHNICAL FIELD

[0001] The application relates to the technical field of putty grinding machines, in particular to a putty grinding machine. BACKGROUND

[0002] The putty powder mixer, also known as a putty powder mixing machine, is mainly composed of carbon steel and stainless steel, and is a mixing device for making putty powder. The putty powder mixing machine generally adopts a screw belt stirring working mode, and achieves uniform material stirring effect through the pushing of three layers of screw belts in different directions inside the machine body.

[0003] The existing patent (publication number: CN219744983U) discloses a grinding mechanism for a putty stirring and grinding machine, which comprises a grinding bin, a rotor disc is arranged in the grinding bin, a stirring shaft is inserted at one end of the rotor disc, a cylindrical spring is arranged between the stirring shaft and the rotor disc, an adjusting device is inserted at the other end of the rotor disc, a first grinding disc is fixedly connected to the side of the rotor disc close to the stirring shaft, a second grinding disc is fixedly connected to the inner wall of one side of the grinding bin, the second grinding disc cooperates with the first grinding disc, and a feeding port is arranged on the side of the grinding bin close to the stirring shaft.

[0004] The above-mentioned comparative document points out that the device has reasonable design, stable structure and strong practicability, effectively solves the problem that the grinding mechanism of the existing putty stirring machine has fixed precision grinding and cannot adjust the grinding precision of the putty, and the fineness of the required putty is different under different construction requirements, so it is necessary to buy new putty powder with corresponding precision to re-adjust, thereby reducing the practicability of the putty stirring machine. However, during the pushing process of the stirring blades of the device, extrusion may cause part of the putty to be agglomerated, the agglomerated putty is difficult to achieve uniform and fine effect in the subsequent grinding process, which affects the construction quality, and the extrusion effect may also cause the putty powder to form accumulation or blockage in the stirring barrel, affecting the smoothness of the conveying, and poor conveying will reduce the working efficiency of the stirring and grinding machine, and even cause equipment failure. Practical new type

[0005] In view of the deficiencies of the prior art, the application provides a putty grinding machine, which has the advantages of increasing grinding effect, and solves the problems that the stirring blades of the device push during the process, extrusion may cause part of the putty to be agglomerated, the agglomerated putty is difficult to achieve uniform and fine effect in the subsequent grinding process, which affects the construction quality, and the extrusion effect may also cause the putty powder to form accumulation or blockage in the stirring barrel, affecting the smoothness of the conveying, and poor conveying will reduce the working efficiency of the stirring and grinding machine, and even cause equipment failure.

[0006] To achieve the above objectives, this application provides the following technical solution: a putty grinding machine, comprising a shell, a bracket fixedly connected to the upper end of the shell, an outer grinding blade fixedly connected to the bottom end of the inner wall of the shell, a rotating shaft rotatably connected inside the bracket, three dispersing plates arranged in a circular array fixedly connected to the outer wall of the rotating shaft, a positioning post fixedly connected to the bottom end of the rotating shaft, a threaded post fixedly connected to the bottom end of the positioning post, a spring fixedly connected to the bottom end of the rotating shaft, an inner grinding blade slidably connected to the outer wall of the positioning post, and an adjusting bolt threadedly connected to the outer wall of the threaded post.

[0007] Through the above-described scheme, the putty is effectively dispersed before entering the grinding area by the dispersing plate driven by the rotating shaft, making its distribution more uniform and thus improving the grinding efficiency and uniformity. At the same time, the cooperation between the outer and inner grinding blades ensures that the putty is fully and meticulously ground. Utilizing the design of the threaded column and adjusting bolt, users can easily adjust the gap between the inner and outer grinding blades, thereby achieving precise control over the grinding accuracy. This adjustability allows the grinder to adapt to the grinding needs of different putty materials. Users can adjust the grinding accuracy simply by rotating the adjusting bolt, without the need for complicated tools or operating procedures, simplifying the operation process.

[0008] Furthermore, a hopper is fixedly connected to the upper end of the outer shell, and multiple discharge slots arranged in a circular array are opened at the bottom of the hopper. A fixing block is fixedly connected to the outer wall of the rotating shaft, and four rotating plates arranged in a circular array are fixedly connected to the outer wall of the fixing block.

[0009] With the above scheme, the hopper serves as the inlet for the putty material. The multiple discharge slots arranged in a ring at the bottom of the hopper ensure that the putty material falls evenly into the grinding area. The fixed block and the four rotating plates arranged in a ring on its outer wall rotate under the drive of the rotating shaft, stirring the putty material entering the hopper so that the putty powder can pass smoothly through the discharge slots.

[0010] Furthermore, a top cover is fixedly connected to the upper end of the hopper, and a motor is fixedly connected to the upper end of the top cover. The output end of the motor passes through one end of the top cover and is fixedly connected to the rotating shaft through a coupling.

[0011] With the above scheme, the motor is fixedly connected above the hopper through the upper cover, and its output end passes through the upper cover and is fixedly connected to the rotating shaft through the coupling. This design ensures that the power output of the motor can be stably and efficiently transmitted to the rotating shaft, thereby driving the operation of components such as the dispersing plate, rotating plate and grinding mechanism.

[0012] Furthermore, a flip cover is rotatably connected to one side of the upper cover via a hinge.

[0013] The above solution allows users to easily open and close the hopper inlet. When adding putty material, users can simply flip the lid to pour the material into the hopper without disassembling or moving the entire lid, thus improving the efficiency of material addition and simplifying the operation process.

[0014] Furthermore, a collection box is fixedly connected to the bottom of the outer shell, and a sliding box is slidably connected inside the collection box.

[0015] The above solution allows the sliding box to be collected in a concentrated manner after grinding. The sliding connection design of the sliding box inside the collection box allows users to easily pull the sliding box out or push it into the collection box.

[0016] Furthermore, the end of the spring away from the rotating shaft is fixedly connected to the inner grinding blade.

[0017] With the above solution, by adjusting the threaded connection between the bolt and the threaded post, the user can precisely adjust the gap between the inner and outer grinding tools, while the spring ensures that the inner grinding tool is always pressed against the upper end of the adjusting bolt during the adjustment process, thereby maintaining the accuracy and stability of the adjustment.

[0018] Furthermore, the inner grinding cutter is rotatably disposed inside the outer grinding cutter.

[0019] Through the above scheme, the close cooperation between the inner and outer grinding blades forms a highly efficient grinding zone. When the two rotate relative to each other, the putty material is clamped between them and subjected to shearing and extrusion from two directions. This makes the shearing and extrusion forces generated during the grinding process more uniform and stable, which helps to grind the putty material more finely and evenly, and shortens the grinding time.

[0020] Furthermore, the fixing block is rotatably disposed inside the hopper.

[0021] With the above solution, when the putty material is added to the hopper, the rotation of the fixed block drives the rotating plate to rotate, which helps to evenly disperse the material, reduce the accumulation and blockage of the material in the hopper, and ensure that the putty material can smoothly enter the grinding area.

[0022] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0023] This putty grinding machine uses a rotating shaft to drive a dispersing plate, which effectively disperses the putty before it enters the grinding area, making its distribution more uniform and improving grinding efficiency and uniformity. Simultaneously, the combined action of the outer and inner grinding blades ensures thorough and meticulous grinding of the putty. Utilizing a threaded post and adjusting bolt design, users can easily adjust the gap between the inner and outer grinding blades, achieving precise control over grinding accuracy. This adjustability allows the grinding machine to adapt to the grinding needs of different putty materials. Users can adjust the grinding accuracy simply by rotating the adjusting bolt, eliminating the need for complex tools or operating procedures and simplifying the operation process.

The cooperation between the outer grinding blade 3 and the inner grinding blade 9 ensures that the putty is fully and finely ground. A rotating shaft 4 is rotatably connected inside the support 2. Three dispersing plates 5 arranged in a ring array are fixedly connected to the outer wall of the rotating shaft 4. The dispersing plates 5 driven by the rotating shaft 4 effectively disperse the putty before it enters the grinding area, making its distribution more uniform, thereby improving the grinding efficiency and uniformity. A positioning post 6 is fixedly connected to the bottom end of the rotating shaft 4, and a threaded post 7 is fixedly connected to the bottom end of the positioning post 6. A spring 8 is fixedly connected to the bottom end of the rotating shaft 4. The inner grinding blade 9 is slidably connected to the outer wall of the positioning post 6, and an adjusting bolt 10 is threadedly connected to the outer wall of the threaded post 7. With the design of the threaded post 7 and the adjusting bolt 10, the user can easily adjust the gap between the inner grinding blade 9 and the outer grinding blade 3, thereby achieving precise control of the grinding accuracy. This adjustability allows the grinding machine to adapt to the grinding needs of different putty materials.

[0033] Please see Figure 1 , Figure 4 and Figure 5 A hopper 11 is fixedly connected to the upper end of the outer shell 1. Multiple discharge slots 12 arranged in a circular array are opened at the bottom of the hopper 11. A fixing block 13 is fixedly connected to the outer wall of the rotating shaft 4. Four rotating plates 14 arranged in a circular array are fixedly connected to the outer wall of the fixing block 13. The hopper 11 serves as the inlet for the putty material. The multiple discharge slots 12 arranged in a circular array at the bottom of its interior ensure that the putty material falls evenly into the grinding area. The fixing block 13 and the four rotating plates 14 arranged in a circular array fixedly connected to its outer wall rotate under the drive of the rotating shaft 4, stirring the putty material entering the hopper 11, allowing the putty powder to pass smoothly through the discharge slots 12. A top cover 15 is fixedly connected to the upper end of the hopper 11. A motor 16 is fixedly connected to the upper end of the top cover 15. The output end of motor 16 passes through the top cover 15 and is fixedly connected to the rotating shaft 4 via a coupling. Motor 16 is fixedly connected above hopper 11 via the top cover 15, and its output end passes through the top cover 15 and is fixedly connected to the rotating shaft 4 via a coupling. This design ensures that the power output of motor 16 can be stably and efficiently transmitted to the rotating shaft 4, thereby driving the operation of components such as the dispersing plate 5, rotating plate 14, and grinding mechanism. A flip cover 17 is rotatably connected to one side of the top cover 15 via a hinge. The design of the flip cover 17 allows users to easily open and close the inlet of hopper 11. When it is necessary to add putty material, users only need to gently flip the flip cover 17 to pour the material into hopper 11 without disassembling or moving the entire top cover 15, which improves the efficiency of material addition and simplifies the operation process.

[0034] Please see Figure 3 , Figure 4 and Figure 5A collection box 18 is fixedly connected to the bottom of the outer casing 1. A sliding box 19 is slidably connected inside the collection box 18. The design of the sliding box 19 allows for the concentrated collection of ground putty powder. The sliding connection design of the sliding box 19 inside the collection box 18 allows the user to easily pull out or push the sliding box 19 into the collection box 18. The end of the spring 8 away from the rotating shaft 4 is fixedly connected to the inner grinding blade 9. By adjusting the threaded connection between the adjusting bolt 10 and the threaded post 7, the user can precisely adjust the gap between the inner grinding blade 9 and the outer grinding blade 3. The spring 8 ensures that the inner grinding blade 9 is always pressed against the upper end of the adjusting bolt 10 during the adjustment process, thereby maintaining the accuracy and stability of the adjustment. The inner grinding blade 9 rotates... The inner grinding blade 9 and the outer grinding blade 3 are set inside the outer grinding blade 3. The close cooperation between them forms a high-efficiency grinding zone. When the two rotate relative to each other, the putty material is clamped between them and subjected to shearing and extrusion from two directions. This makes the shearing and extrusion forces generated during the grinding process more uniform and stable, which helps to grind the putty material more finely and evenly, and shortens the grinding time. The fixing block 13 is rotatably set inside the hopper 11. When the putty material is added to the hopper 11, the rotation of the fixing block 13 drives the rotating plate 14 to rotate, which helps to evenly disperse the material and can reduce the accumulation and blockage of the material in the hopper 11, ensuring that the putty material can smoothly enter the grinding zone.

[0035] In this embodiment, the putty grinding machine uses a dispersing plate 5 driven by a rotating shaft 4 to effectively disperse the putty before it enters the grinding area, making its distribution more uniform and thus improving the grinding efficiency and uniformity. At the same time, the cooperation between the outer grinding blade 3 and the inner grinding blade 9 ensures that the putty is ground thoroughly and meticulously. Utilizing the design of the threaded post 7 and the adjusting bolt 10, the user can easily adjust the gap between the inner grinding blade 9 and the outer grinding blade 3, thereby achieving precise control over the grinding accuracy. This adjustability allows the grinding machine to adapt to the grinding needs of different putty materials. The user only needs to rotate the adjusting bolt 10 to adjust the grinding accuracy, without the need for complicated tools or operating procedures, simplifying the operation process.

[0036] The working principle of the above embodiments is as follows:

[0037] The user first opens the flip cover 17 and pours the putty material into the hopper 11. Once the putty material enters the hopper 11, the motor 16 starts, driving the rotating shaft 4 to rotate. The rotation of the shaft 4 not only drives the dispersing plate 5 but also rotates the fixed block 13 and its rotating plate 14. The rotation of the rotating plate 14 further stirs the putty material in the hopper 11, preventing accumulation and blockage, and ensuring that the putty material can smoothly enter the grinding area through the discharge chute 12. The rotation of the dispersing plate 5 helps to initially disperse the putty material during the dispersing stage, making its distribution more uniform. The putty material falls through the discharge chute 12 into the grinding area between the outer grinding blade 3 and the inner grinding blade 9. The inner grinding blade 9 is connected to the adjusting bolt 10 via the spring 8, ensuring that it grinds evenly. During the process, the inner grinding blade 9 is always pressed against the upper end of the adjusting bolt 10, maintaining a stable gap with the outer grinding blade 3. The motor 16 continues to drive the rotating shaft 4 to rotate, thereby causing the inner grinding blade 9 to rotate relative to the outer grinding blade 3. During this process, the putty material is clamped between the inner and outer grinding blades 3 and subjected to shearing and squeezing from two directions, thus being fully and meticulously ground. The ground putty powder falls into the sliding box 19 in the collection box 18 through the outlet of the grinding area. After grinding, the user can easily pull the sliding box 19 out of the collection box 18 to collect the ground putty powder. The user can adjust the gap between the inner grinding blade 9 and the outer grinding blade 3 by rotating the adjusting bolt 10 as needed, thereby achieving precise control of the grinding accuracy.
