Description

Technical Field

[0001] This utility model relates to the field of medical coating colloid technology, and in particular to a medical coating colloid mixing and application device. Background Technology

[0002] Medical coating colloids are colloidal materials used in medical dressings. These colloids are typically mixtures of microparticles and molecules, ranging in size from 1 nanometer to 1000 nanometers. Medical coating colloids have wide applications in the medical field, primarily in the manufacture of medical dressings such as medical adhesive tapes and hydrocolloid dressings. A medical coating colloid mixing application device is a specialized piece of equipment used to mix and stir the colloids during the medical coating process. This type of equipment plays a crucial role in the manufacture of medical products, especially in the production of various medical patches.

[0003] To address this, patent CN214210212U discloses a raw material mixing and stirring device for medical aqueous colloidal rolls. This device facilitates control over the dosage of two sets of raw materials, thereby improving the mixing effect, reducing limitations, and enhancing practicality. It includes a housing, a mounting frame, a control panel, a storage tank, a partition, a first suction pump, a second suction pump, a first guide pipe, a second guide pipe, two sets of flow valves, and a discharge pipe. The housing contains a processing chamber. The control panel is fixed to the front of the housing via the mounting frame. The partition is installed inside the storage tank, dividing it into two storage chambers. Two sets of raw materials are respectively installed in the storage chamber. The inlet end of the discharge pipe passes through the lower right end of the box and communicates with the processing chamber. A heating device is installed on the inner wall of the processing chamber. A stirring device is installed inside the box. The control panel is electrically connected to the first suction pump, the second suction pump, two sets of flow valves, the heating device, and the stirring device. During use, the raw material mixing and stirring equipment for the medical aqueous colloidal roll heats the colloidal material inside the box by heating the heating plate. As a result, the colloidal material located in the middle of the box is not heated sufficiently during the stirring process, which leads to local overheating or underheating of the colloidal material, thereby reducing the reaction rate between the colloidal materials.

[0028] The motor 501 drives the shaft 502 to rotate the drive gear 503. The drive gear 503 meshes with the driven gear 504, causing the driven gear 503 to rotate. The rotation of the driven gear 504 then drives the stirring shaft 505, which in turn rotates the stirring rod 506 to stir the colloid inside the tank 1. Simultaneously, the stirring rod 506 rotates the scraper 507 during the stirring process, making it easier to scrape off the colloid adhering to the inner wall of the tank 1, facilitating cleaning and ensuring more thorough mixing of the colloid. Since the scraper 507 is made of rubber, it will not damage the inner wall of the tank 1 during the scraping process, thus improving its practicality during use.

The inside of the water supply pipe 603 is connected to the inside of the first heating chamber 607. The inside of the first heating chamber 607 is connected to the inside of the first sealing ring 608. The water pumping pipe 610 and the stirring shaft 505 are sealed together by the second sealing ring 611.

A fixing block 605 is installed so that it remains stationary within the rotating groove 606 during the rotation of the driven gear 504. While the stirring shaft 505 and stirring rod 506 stir the colloid inside the tank 1, they also heat the colloid. Combined with the heating plate 614, this ensures more uniform heating of the colloid inside the tank 1, increasing the molecular motion speed and collision frequency, which is beneficial for the reaction and accelerates the colloid formation rate. It also prevents sedimentation of the colloid. This improves the stability of the colloid. By activating the water pump 612, the water pipe 610 draws hot water from the first heating chamber 607 and the first sealing ring 608, which then flows back into the heating box 601 through the return pipe 613 for reheating. The hot water then re-enters the first heating chamber 607 and the first sealing ring 608 through the water supply pipe 603, facilitating the recycling of hot water and ensuring the heating effect. At the same time, a temperature sensor is installed inside the tank 1, allowing the control panel to display the temperature inside the tank 1 on the screen, making it easy for people to observe the temperature inside the tank 1 and control the appropriate temperature and time. When the stirring process ends or the set temperature is reached, the valve 604 and the water pump 612 are closed to stop heating and prevent the colloid from completely agglomerating.
