Description

Technical Field

[0001] The embodiments disclosed herein relate to the technical field of filter paper processing mixing equipment, specifically, to a mixer for coffee filter paper production. Background Technology

[0002] Coffee filter paper is a tool used to filter coffee liquid. Its main function is to remove coffee grounds and impurities, ensuring that the brewed coffee is pure and flawless. During the production of coffee filter paper, the mixer is crucial for the uniform mixing of raw materials, which directly affects the product quality. However, the mixers currently used in the production of coffee filter paper have significant shortcomings.

[0003] Regarding material discharge, existing mixers have simple discharge methods and a single discharge port design, often with bottom discharge. This makes it easy for the mixed material to become clogged during discharge, especially when the material contains special components such as fibers, resulting in extremely low discharge efficiency and seriously affecting production progress. Moreover, discharge is often incomplete, and residual material leads to raw material waste.

[0004] Cleaning is equally troublesome. The mixer's internal structure is complex, and material easily remains on the mixing blades and the tank walls. During cleaning, it is difficult for manual labor to reach some corners, resulting in incomplete cleaning. Furthermore, the cleaning process is tedious, requiring a lot of time and effort to disassemble parts, increasing labor costs, and frequent cleaning can also affect the equipment's lifespan.

[0005] As the market demand for coffee filter paper grows and production scales up, these problems become increasingly prominent. Therefore, designing a mixer for coffee filter paper production that facilitates easy discharge and cleaning is urgently needed. This will effectively improve production efficiency, reduce costs, and ensure product quality. Utility Model Content

[0034] like Figures 1-4 As shown, a mixer for producing coffee filter paper is illustrated in one embodiment of this disclosure, comprising:

[0035] The base plate 1 and the mixing tank 2 are fixed on the base plate 1;

[0036] The sealing plate 3 and the lifting and pushing assembly 5 are provided. The sealing plate 3 is slidably attached to the inner wall of the mixing tank 2, and the lifting and pushing assembly 5 is disposed between the sealing plate 3 and the mixing tank 2.

[0037] The column 4 and the stirring assembly 6 are provided, wherein the column 4 is fixed on the surface of the sealing plate 3 and the stirring assembly 6 is disposed on the column 4;

[0038] The lifting and pushing assembly 5 includes a drive motor 5-1, which is fixed to the bottom of the mixing tank 2. A drive screw 5-2 is provided at the output end of the drive motor 5-1. One end of the drive screw 5-2 extends into the interior of the column 4. The column 4, the drive screw 5-2, and the sealing plate 3 are connected by a threaded connection. A discharge pipe 5-3 is provided on the outer wall of the mixing tank 2. A baffle 5-4 is connected to the top of the mixing tank 2 by a pin. A groove 5-5 is provided on the top of the mixing tank 2. An inner rod 5-6 is provided in the groove 5-5. A slider 5-7 is slidably connected to the inner rod 5-6. The slider 5-7 slides against the inner wall of the groove 5-5. A spring 5-8 is fitted on the inner rod 5-6. A slot 5-9 is provided on the surface of the baffle 5-4. A locking rod 5-10 is provided on the upper end face of the slider 5-7. The locking rod 5-10 is inserted into the slot 5-9.

[0039] In some examples, within the pulp processing flow, a lifting and pushing assembly 5 is designed to efficiently discharge the pulp from the mixing tank 2 and facilitate cleaning of the tank after emptying. This assembly includes a drive motor 5-1 fixed to the bottom of the mixing tank 2, which provides power. A drive screw 5-2, located at the output end, is situated inside the column 4. When the drive motor 5-1 starts, it rotates the drive screw 5-2. The column 4 and the drive screw 5-2 are connected via a threaded connection. The rotation of the drive screw 5-2 causes the column 4 to move linearly along the screw, thereby pushing the sealing plate 3 upwards. As the sealing plate 3 rises, the pulp inside the mixing tank 2 is gradually pushed upwards and finally discharged through the discharge pipe 5-3 located on the outer wall of the mixing tank 2. The baffle 5-4 at the top of the mixing tank 2 is connected by a pin and is normally closed to prevent pulp from overflowing. An inner rod 5-6 is installed in the groove 5-5 at the top of the mixing tank 2. A slider 5-7 is slidably connected to the inner rod 5-6. The slider 5-7 slides against the inner wall of the groove 5-5, and a spring 5-8 is installed on the inner rod 5-6. A slot 5-9 is provided on the surface of the baffle 5-4, and a locking rod 5-10 on the upper end of the slider 5-7 is inserted into the slot 5-9. This structure allows the baffle 5-4 to remain stably closed during the pulp discharge process. After the pulp in the mixing tank 2 is emptied, the baffle 5-4 can be opened for cleaning. The baffle 5-4 can be opened around the pin, allowing the operator to thoroughly clean the inside of the mixing tank 2.

[0040] like Figures 1-4 As shown in the figure, the stirring assembly 6 in this embodiment includes a sealing cover 6-1, which is fixed to the side surface of the column 4. A first stirring motor 6-2 is installed in the sealing cover 6-1. A bottom stirring frame 6-3 is provided at the output end of the first stirring motor 6-2. A connecting frame 6-4 is provided on the surface of the sealing plate 3. A second stirring motor 6-5 is installed on the connecting frame 6-4. A central stirring frame 6-6 is provided at the output end of the second stirring motor 6-5.

[0041] In some examples, during actual pulp processing operations, a mixing assembly 6 is specially designed to ensure thorough mixing of the pulp in the mixing tank 2, guaranteeing its uniformity and quality. This assembly includes a sealing cover 6-1 fixed to the side surface of the column 4, inside which a first mixing motor 6-2 is installed. The sealing cover 6-1 protects the first mixing motor 6-2, preventing pulp and other substances from entering the motor and affecting its normal operation. The output end of the first mixing motor 6-2 is connected to the bottom mixing frame 6-3. When the first mixing motor 6-2 starts, it drives the bottom mixing frame 6-3 to rotate. The bottom mixing frame 6-3 can stir the pulp at the bottom of the mixing tank 2, preventing the pulp from accumulating and settling at the bottom, so that the pulp at the bottom can also participate in the overall mixing process. At the same time, a second mixing motor 6-5 is installed on the connecting frame 6-4 on the surface of the sealing plate 3, and the output end of the second mixing motor 6-5 is connected to the central mixing frame 6-6. After the second stirring motor 6-5 starts, the central stirring rack 6-6 begins to rotate, stirring the pulp in the center of the mixing tank 2. The rotation of the central stirring rack 6-6 can create a dynamic mixing zone in the center of the mixing tank 2, enhancing the fluidity of the pulp.

[0042] For example, such as Figure 1 As shown, the baffle 5-4 has a semi-circular structure and is sealed to the upper surface of the mixing tank 2.

[0043] In some examples, the sealing effect of the baffle 5-4 enables it to seal, preventing pulp from overflowing through the gaps during discharge.

[0044] For example, such as Figure 3 As shown, the mixing tank 2 is fixed to the base plate 1 at a 45° angle.

[0045] In some examples, the 45° tilt angle allows the pulp to be concentrated at the discharge pipe 5-3, maximizing the emptying of the pulp and facilitating flushing.

[0046] For example, such as Figure 3 As shown, the discharge pipe 5-3 has an overall L-shaped structure, with the open end of the discharge pipe 5-3 facing upwards.

[0047] In some examples, the L-shaped structure allows the discharge pipe 5-3 to extend upwards, facilitating the discharge of material at the angle of the mixing tank 2. The bending angle of the discharge pipe 5-3 can be changed according to the actual situation to avoid residual pulp inside.

[0048] In actual use: The raw materials are poured into the mixing tank 2, which is fixed at a 45° angle to the bottom plate 1 through the top opening of the mixing tank 2. The inclined design allows the raw materials to naturally gather towards the discharge pipe 5-3, reducing bottom accumulation. When the mixing assembly 6 is started, the first mixing motor 6-2 inside the sealing cover 6-1 fixed to the side surface of the column 4 drives the bottom mixing frame 6-3 to rotate at high speed after being powered on, which fully agitates the raw materials close to the bottom of the tank, preventing fibrous materials from settling. At the same time, the second mixing motor 6-5 on the connecting frame 6-4 on the surface of the sealing plate 3 starts synchronously, driving the central mixing frame 6-6 to form a spiral mixing flow in the central area of ​​the mixing tank 2, forming a three-dimensional mixing field with the bottom mixing frame 6-3, ensuring that the pulp, fiber and additives are mixed evenly in the tank without dead corners. After the mixing is completed, the drive motor 5-1 of the lifting and pushing assembly 5 is started, and the drive screw 5-2 at its output end begins to rotate clockwise. Through the threaded engagement with the inner wall of the column 4, the rotational motion is converted into the linear upward motion of the column 4, which in turn pushes the sealing plate 3 to slide upward along the inner wall of the mixing tank 2. Because the sealing plate 3 fits tightly against the barrel wall, a rigid pushing surface is formed during the upward movement, gradually pushing the mixed material along the barrel wall to the L-shaped discharge pipe 5-3. The upward-facing design of the pipe opening, combined with the tilt angle of the mixing barrel, allows the material to be discharged smoothly under the action of gravity and thrust, avoiding the clogging problem of traditional bottom discharge. After the discharge is completed, operate the slider 5-7 located in the groove 5-5 at the top of the mixing barrel 2 to disengage the locking rod 5-10 from the slot 5-9 on the surface of the baffle 5-4. Then, rotate the semi-circular baffle 5-4 upward around the pin axis. At this time, the sealing plate 3, the mixing rack, and the barrel wall can be thoroughly cleaned. The tilted barrel design, combined with the dead-angle-free space after the sealing plate rises, allows cleaning tools to directly contact the inner wall and effectively remove residual material. After completion, reset the baffle 5-4, and the locking rod 5-10 is re-locked into the slot 5-9 under the action of the spring 5-8, restoring the sealing state.

[0049] It should be noted that the above embodiments are only used to illustrate the technical solutions of this disclosure and are not intended to limit it. Although this disclosure has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this disclosure without departing from the spirit and scope of the technical solutions of this disclosure, and all such modifications and substitutions should be covered within the scope of the claims of this disclosure.
