Description

Technical Field

[0001] This utility model relates to the technical field of mixing tanks, and in particular to the technical field of a small-batch material mixer. Background Technology

[0002] In fields such as battery and pharmaceutical research, materials often require stirring, cutting, or grinding to meet the needs of subsequent processing or experiments. For example, in the processing of traditional Chinese medicine, herbs need to be crushed to a specific particle size to extract active ingredients, while ensuring that the activity of the herbs is not damaged by temperature changes during processing. In the experimental preparation of small-batch battery raw materials, the material processing process requires strict temperature control to avoid fire or chemical reactions caused by high temperatures, while also achieving uniform crushing and mixing to ensure stable raw material performance. However, existing material processing equipment has many shortcomings in practical applications: existing equipment lacks a temperature regulation structure for the material processing environment, and cannot maintain a constant optimal processing temperature based on material characteristics (such as maintaining the activity of traditional Chinese medicine and preventing high-temperature reactions in battery raw materials), leading to a decline in material quality or reduced processing safety. Insufficient material processing efficiency and uniformity: some equipment only has a single stirring or grinding function. For materials that require cutting before further processing, this must be done separately by equipment or in steps, resulting in a cumbersome and inefficient process. Furthermore, unreasonable stirring structure design can easily lead to localized material accumulation and uneven crushing, especially for materials with high viscosity or large particle size differences, making it difficult to achieve comprehensive and uniform processing. Utility model patent CN202222853195.7 discloses a mixing tank for cosmetic production. This mixing tank uses the extension and retraction of the output shafts of two cylinders to drive the threaded rods connected to them to move up and down while rotating inside the mixing tank body. This effectively solves the problem that the mixing blades generally rotate in a fixed position in the mixing tank, and the liquid in other parts may not be fully stirred and emulsified, resulting in low emulsification efficiency of cosmetics. However, this equipment cannot precisely control the temperature, and the degree of automation is low, making it impossible to monitor the entire processing process. Summary of the Invention

[0003] The purpose of this invention is to solve the problems in the prior art by proposing a small-batch material mixer, which solves the problems of existing mixing equipment having single function, low degree of automation, and inability to accurately control the temperature and monitor the process of the mixing environment.

[0004] To achieve the above objectives, this utility model proposes a small-batch material mixer, including a base, a mixing tank, a lifting seat, a cover, a mixing and cutting mechanism, and a lifting power mechanism. A mixing tank for holding materials at a set temperature is fixed to one side of the base. The mixing tank is covered with a cover, which is fixed to the lifting seat. The lifting seat is equipped with a mixing and cutting mechanism that passes through the cover to mix and cut the materials inside the mixing tank. A lifting power mechanism is provided on the other side of the base to control the opening and closing of the cover and the mixing tank by raising and lowering the lifting seat. The mixing tank includes a temperature control box, a tank body, and pipe joints. The barrel is a conical shape with an open top and a closed bottom. The upper end of the barrel is sealed to the upper end of the temperature control box, and the lower end of the barrel and the lower end of the temperature control box form a closed temperature control chamber. The temperature control box is equipped with a pipe joint that communicates with the temperature control chamber. The temperature control box is a cylindrical shape with a closed bottom, and a sealing ring is provided between the upper end of the temperature control box and the upper end of the barrel. The top of the cover is provided with a material turning and venting hole, and the bottom of the mixing barrel is provided with a material turning and venting hole. An air pump is provided between the material turning and venting holes, and the exhaust pipe of the air pump is connected to the material turning and venting hole. The air pump's intake pipe is connected to the material turning and venting hole.

[0005] Preferably, the cover is provided with an observation hole, and an observation tube is provided on the observation hole. The lower end of the observation tube is connected to the inside of the cover, and the upper end is provided with a glass plate.

[0006] Preferably, the observation tube is equipped with a light for illuminating the materials inside the mixing tank.

[0007] Preferably, the lifting power mechanism includes a lifting power base, a lifting power motor, a lifting power lead screw, a lifting power sleeve, and a support base. The lifting power motor is fixedly mounted on the lifting power base, and the rotation shaft of the lifting power motor is connected to the lower end of the lifting power lead screw. The support base is fixedly mounted on the upper end of the lifting power lead screw, and a lifting power sleeve is fitted on the lifting power lead screw. The lifting power sleeve is fixedly mounted on the lifting base.

[0008] Preferably, the lifting power mechanism further includes a lifting guide rod, which passes through the upper end of the lifting seat and is fixed to the support seat, and the lower end is fixed to the base.

[0009] Preferably, the stirring and cutting mechanism includes a stirring power base, a stirring power motor, a stirring shaft, a stirring conveyor belt, and a stirring pulley. The stirring power motor is fixedly mounted on the stirring power base. One end of the stirring shaft passes through the cover and is located in the stirring tank, while the other end is provided with a stirring pulley. The stirring pulley is connected to the rotating shaft of the stirring power motor via the stirring conveyor belt. A cutting blade is fixedly mounted at one end of the stirring shaft located in the stirring tank.

[0010] Preferably, the mixing and cutting mechanism further includes a tensioning wheel, and the lifting seat is provided with a tension adjustment elongated hole. The tensioning wheel is fixed in the tension adjustment elongated hole and supports the mixing conveyor belt.

[0011] The beneficial effects of this utility model are as follows: By precisely controlling the temperature of the mixing tank, this utility model allows materials to be cut and mixed in optimal condition, resulting in high efficiency, high safety, and guaranteed quality of the finished product. A closed temperature control chamber is formed between the temperature control box and the tank body, through which a temperature-regulating medium at the set temperature is introduced, achieving indirect and constant temperature control of the materials inside the tank. The material turning and venting hole at the top of the lid and the material turning and venting hole at the bottom of the mixing tank form a closed airflow circulation loop via an air pump. The airflow rushes in from the bottom of the tank, causing the materials to turn over, ensuring full contact between the materials and the cutting blades, solving the problems of localized material accumulation and uneven crushing. Furthermore, the airflow does not overflow and does not affect the surrounding environment. Simultaneously, by setting an observation port on the lid, the entire mixing process can be monitored, ensuring that the material mixing and cutting meet the requirements. The equipment also boasts a high degree of automation and is simple and convenient to operate. Attached Figure Description

Detailed Implementation

[0014] See Figure 1 and Figure 2This utility model discloses a small-batch material mixer, comprising a base 1, a mixing tank 2, a lifting seat 3, a cover 4, a lifting power mechanism 5, and a mixing and cutting mechanism 6. The mixing tank 2 is fixedly installed on one side of the base 1 to ensure a firm connection between the mixing tank 2 and the base 1 without loosening. The cover 4 is fixed to the lower part of the lifting seat 3 by bolts or welding, so that the cover 4 can rise and fall synchronously with the lifting seat 3, and the size of the cover 4 matches the upper opening size of the mixing tank 2. The lifting power mechanism 5 is installed on the other side of the base 1, and its lifting power screw sleeve 54 is fixedly connected to the lifting seat 3 to realize the lifting power mechanism 5 to drive the lifting seat 3 to rise and fall. The mixing and cutting mechanism 6 is assembled on the lifting seat 3, and the mixing shaft 63 of the mixing and cutting mechanism 6 extends through the cover 4 into the interior of the mixing tank 2, ensuring that the cutting blade at the lower end of the mixing shaft 63 can rotate normally inside the mixing tank 2 to complete the material cutting and mixing action.

[0015] The mixing tank 2 includes a temperature control box 21, a tank body 22, a pipe joint 23, and a sealing ring 24, such as Figure 2 , Figure 3 As shown, specifically, the barrel 22 is designed as a conical shape with an open top and a closed bottom. This shape facilitates the concentration of materials inside the barrel, reducing material accumulation. The upper end of the barrel 22 is sealed to the upper end of the temperature control box 21 through a sealing ring 24, forming a closed temperature control chamber between the lower end of the barrel 22 and the lower end of the temperature control box 21. The sealing ring 24 effectively prevents the temperature-regulating water or air inside the temperature control chamber from leaking into the barrel 22, while also preventing materials from mixing into the temperature control chamber. A pipe joint 23 is welded or threaded onto the side wall of the temperature control box 21, and the pipe joint 23 communicates with the interior of the temperature control chamber. During use, temperature-regulating water or air at a precise temperature is circulated into the temperature control chamber through the pipe joint 23. For the processing of traditional Chinese medicine, temperature-regulating water at the same temperature as the herbal medicine is injected to maintain a constant temperature inside the barrel 22 to ensure the activity of the medicinal materials. For the processing of small batches of battery raw materials, low-temperature air is injected to prevent the temperature inside the barrel 22 from becoming too high, which could cause the raw materials to catch fire or undergo a chemical reaction.

[0016] The structural design of the cover 4 mainly meets the requirements of sealing, observation, and airflow circulation. An observation hole 41 is opened in the middle of the cover 4, such as... Figure 1 , Figure 2As shown, it is understandable that the aperture of the observation hole 41 is set according to actual observation needs. The observation tube is vertically fixed to the observation hole 41, with its lower end connected to the inside of the cover 4 and its upper end fixed to the glass plate with sealant. The operator can observe the crushing and mixing status of the material inside the mixing tank 2 in real time through the glass plate without stopping the machine for inspection. A light is installed on the inner wall of the observation tube, and the power cord of the light extends through the side wall of the observation tube to the external power source of the equipment. When the light is turned on, it can illuminate the inside of the mixing tank 2, which is especially clear when processing dark materials. The crushing state of the material is identified; a turning and venting hole is opened on the top of the cover 4, which is used in conjunction with the turning and venting hole at the bottom of the mixing tank 2. The exhaust pipe of the air pump is connected to the turning and venting hole, and the air inlet pipe of the air pump is connected to the turning and venting hole; after the air pump is started, the high-speed airflow rushes into the mixing tank 2 from the turning and venting hole, causing the material in the tank to turn over, so that the material is in full contact with the cutting blade, ensuring the uniformity of mixing and cutting. At the same time, the airflow is discharged from the turning and venting hole and flows back to the air pump, forming an airflow circulation, while avoiding the overflow of airflow from affecting the surrounding environment of the equipment.

[0017] The lifting power mechanism 5 includes a lifting power base 51, a lifting power motor 52, a lifting power lead screw 53, a lifting power screw sleeve 54, a lifting guide rod 55, and a support base 56, as follows: Figure 4 As shown, it should be noted that the lifting power seat 51 is fixed to the other side of the base 1 with bolts, ensuring that the lifting power seat 51 is perpendicular to the base 1; the lifting power motor 52 is fixed on the top of the lifting power seat 51, so that the rotation shaft of the lifting power motor 52 is vertically downward, and is connected to the lower end of the lifting power screw 53 through a coupling; the upper end of the lifting power screw 53 is welded and fixed to the support seat 56; the upper end of the lifting guide rod 55 passes through the lifting seat 3 and is fixed to the support seat 56; the lower end of the lifting guide rod 55 is fixed to the base 1, and the lifting guide rod 55 and the lifting power screw 53 are parallel to each other, used to guide the lifting direction of the lifting seat 3 and prevent the lifting seat 3 from deviating during the lifting process. The lifting power sleeve 54 is fitted onto the lifting power screw 53, and the lifting power sleeve 54 is welded or bolted to the lifting seat 3. When it is necessary to open the cover 4, the lifting power motor 52 is started to rotate forward, which drives the lifting power screw 53 to rotate. The lifting power screw 53 drives the lifting power sleeve 54 to move upward, thereby driving the lifting seat 3, the cover 4, and the stirring and cutting mechanism 6 to move upward along the lifting guide rod 55, realizing the separation of the cover 4 from the stirring tank 2. When it is necessary to close the cover 4, the lifting power motor 52 is started to rotate in reverse, and the lifting power sleeve 54 drives the lifting seat 3 and the cover 4 to move downward until the cover 4 completely covers the stirring tank 2, ensuring the sealing reliability of the stirring tank 2.

[0018] The mixing and cutting mechanism 6 includes a mixing power base 61, a mixing power motor 62, a mixing shaft 63, a mixing conveyor belt 64, a mixing pulley 65, and a tensioning pulley 66, as shown below. Figure 2 Specifically, the stirring power base 61 is fixed to the top of the lifting base 3, and the stirring power motor 62 is bolted to the stirring power base 61; one end of the stirring shaft 63 extends through the cover 4 into the mixing tank 2 via a bearing, and a cutting blade is welded to the end of the stirring shaft 63 inside the mixing tank 2. The number and shape of the cutting blades can be set according to the material cutting requirements (e.g., multiple sets of sharp blades can be set for hard materials); the other end of the stirring shaft 63 is welded to the stirring pulley 65, and the stirring pulley 65 and the pulley on the rotating shaft of the stirring power motor 62 are connected by a stirring conveyor belt 64; a tension adjustment elongated hole is opened on the lifting base 3, and a tensioning wheel 66 is fixed in the tension adjustment elongated hole by bolts, and the tensioning wheel 66 contacts and supports the stirring conveyor belt 64; when the stirring conveyor belt 64 is used for a long time... When slack occurs, loosen the fixing bolts of the tension wheel 66 and adjust the position of the tension wheel 66 along the tension adjustment hole (moving it away from the mixing pulley 65) until the mixing conveyor belt 64 returns to a taut state. Then, tighten the bolts to fix the tension wheel 66 to ensure the transmission friction of the mixing conveyor belt 64 and prevent slippage of power transmission. During material processing, start the mixing power motor 62. The mixing power motor 62 drives the mixing pulley 65 and the mixing shaft 63 to rotate at high speed through the mixing conveyor belt 64. The cutting blade at the lower end of the mixing shaft 63 cuts the material in the mixing tank 2. At the same time, the rotation of the mixing shaft 63 drives the material to be mixed as a whole, realizing the simultaneous cutting and mixing. For materials that need further grinding, the cut material can be directly ground in the mixing tank 2 without transferring the equipment, which greatly improves the processing efficiency.

[0019] The working process of this utility model: In the operation of this small-batch material mixer, firstly, according to the characteristics of the material to be processed, temperature-controlled water or air at a set temperature is injected into the temperature-controlled chamber of the mixing tank 2 through the pipe joint 23. After the temperature of the temperature-controlled chamber stabilizes, the lifting motor 52 is started to raise the cover 4 and pour the material into the mixing tank 2. Then, the lifting motor 52 is started again to lower the cover 4 and close it on the mixing tank 2. The light in the observation tube is turned on, and the air pump and the stirring motor 62 are started to begin the cutting and stirring of the material. The operator observes the material processing status in real time through the glass plate of the observation tube. After the material processing meets the requirements, the stirring motor 62 is turned off and the lifting motor 52 is started again to raise the cover 4 and remove the processed material from the mixing tank 2, completing one processing cycle.

[0020] This utility model discloses a small-batch material mixer. By precisely controlling the temperature of the mixing tank, the material can be cut and mixed in the optimal state, which is highly efficient, safe, and ensures the quality of the finished product. At the same time, by setting an observation port on the lid, the mixing process can be monitored throughout to ensure that the material mixing and cutting meet the requirements. In addition, the equipment has a high degree of automation and is simple and convenient to operate.
