Description

Technical Field

[0001] This utility model relates to the field of pharmaceutical production equipment technology, specifically to a hot melt adhesive mixing device for traditional Chinese medicine plasters. Background Technology

[0002] Traditional Chinese medicine plasters are topical application medications. By applying them to the skin, the medicated plaster acts directly on the affected area to achieve therapeutic effects. They are commonly used to relieve pain symptoms such as joint pain and muscle aches, and have shown good therapeutic efficacy.

[0003] In the production process of traditional Chinese medicine plasters, a stirring device is required to stir the plaster. When using existing hot melt adhesive stirring equipment to produce plasters, insufficient stirring and incomplete heating of the plaster often lead to uneven mixing of the medicine in the plaster, affecting the quality and efficacy of the traditional Chinese medicine plaster product.

[0004] Based on the above issues, it is necessary to propose a hot melt adhesive mixing device for traditional Chinese medicine plasters to fully mix the plaster, ensuring thorough mixing of the medicine within the plaster, thereby improving production efficiency and guaranteeing the quality and efficacy of the plaster products. Utility Model Content

[0006] To achieve the above-mentioned technical objectives and effects, this utility model solves the above-mentioned problems through the following technical solution:

[0007] A hot melt adhesive mixing device for traditional Chinese medicine plasters includes a mixing tank, a mixing shaft, and a mixing drive device. The mixing tank has a horizontal structure, and the mixing shaft extends horizontally through the mixing tank and is connected to the mixing drive device. The mixing shaft includes two Z-shaped shafts arranged at the front and rear, extending along an Archimedean spiral. The bottom of the mixing tank has an arc-shaped inner wall that matches the rotation range of the Z-shaped shafts. The main mixing shaft at the front is connected to the mixing drive device, and the auxiliary mixing shaft at the rear is connected to the main mixing shaft via a pulley transmission mechanism. The mixing tank has a heat transfer oil jacket and heat transfer oil inlet and outlet holes. The mixing shaft has a heat transfer oil channel, and the path of the heat transfer oil channel matches the Z-shape of the mixing shaft. Both ends of the heat transfer oil channel are connected to heat transfer oil rotary joints. Heat transfer oil enters the heat transfer oil channel from one side of the rotary joint and exits from the other side.

[0008] In the above scheme, two Z-shaped stirring shafts extending along the Archimedean spiral are installed inside the mixing tank. When the material is lifted, it pushes the material on both sides along the spiral to the center of the tank. During the descent, the material flows and cuts between different layers, achieving thorough and uniform mixing to ensure the homogeneity of the material. Simultaneously, heat transfer oil is introduced into the heat-conducting jacket of the tank and the heat-conducting channels inside the stirring shafts. This dual heating method, using both the heat-conducting jacket and the heat-conducting channels with heat transfer oil, ensures that the paste inside the tank is fully heated, maintaining better fluidity and resulting in more thorough and uniform mixing, effectively improving mixing efficiency.

[0009] Furthermore, the mixing tank adopts a tilting discharge method. The mixing tank includes a main tank body and a tank cover that fit together at the top and bottom, and a heat transfer oil jacket is provided in the main tank body. The main stirring shaft is rotatably connected to the base through bearing seats on both sides, and the auxiliary stirring shaft is mounted on the base. A tank body tilting cylinder is hinged on the base, and the piston end of the tank body tilting cylinder is connected to the main tank body to drive it to tilt along the main stirring shaft. The tank cover is hinged to a mounting column on the base, and a tank cover tilting cylinder is hinged on the mounting column. The piston end of the tank cover tilting cylinder is connected to the tank cover to drive it to flip over and cover the top opening of the main tank body.

[0010] Furthermore, the stirring drive device includes a drive motor, a reducer, and a coupling connected in sequence. The coupling connects the output end of the reducer to the main stirring shaft. The output shaft of the reducer and the coupling have a passage for communicating with the heat transfer oil channel. The heat transfer oil rotary joint on the side of the main stirring shaft corresponding to the stirring drive device is installed on the outer end of the output shaft of the reducer.

[0011] Furthermore, the transmission mechanism includes a driving gear and a driven gear with different gear ratios, respectively mounted on the main stirring shaft and the auxiliary stirring shaft. The driving gear and the driven gear mesh to transmit torque. The two Z-shaped stirring shafts are configured with different rotational speeds, which improves the mixing efficiency while the materials are tumbling, making the paste less likely to clump together and improving product quality.

[0012] Furthermore, it also includes a heat transfer oil heating station. The cooling oil output from the heat transfer oil jacket and heat transfer oil channel enters the heat transfer oil heating station for heating, and then is returned to the heat transfer oil jacket and heat transfer oil channel to heat the paste.

[0013] Furthermore, the mixing tank is equipped with a vacuum connector, a temperature sensor, and an observation window.

[0014] The advantages and effects of this utility model are:

[0015] 1. This design features two Z-shaped stirring shafts that extend along the Archimedes spiral. These two Z-shaped stirring shafts can lift and push the material on both sides of the tank to the center. During the material's descent, it flows and cuts between different layers, achieving thorough and uniform mixing to ensure the homogeneity of the material.

[0016] Furthermore, by configuring the two Z-shaped stirring shafts with different speeds, the mixing efficiency can be improved while the materials are being turned over, making it less likely for the paste to clump together and improving product quality.

[0017] 2. This solution introduces heat transfer oil into the heat-conducting jacket of the tank and the heat-conducting channel of the stirring shaft. Through the dual heating method of heat transfer oil in the heat-conducting jacket and heat-conducting channel, the heat exchange area of ​​the paste in the tank can be increased, so that the paste is fully heated and maintains better fluidity, and the stirring is more thorough and uniform.

[0018] 3. This solution adopts a tilting discharge method. The main tank and the tank cover are tilted by a hydraulic cylinder, which can quickly realize the combination and disassembly of the mixing tank. The main tank is tilted as a whole by the hydraulic cylinder for discharge, resulting in higher discharge efficiency and cleaner discharge. Attached Figure Description
