Description

Technical Field

[0001] This utility model relates to the technical field of scraping devices for mixing equipment, specifically a high-efficiency scraping device for hydrogel patch mixing equipment. Background Technology

[0002] During the production of hydrogel patches, the polymer gel material, active pharmaceutical ingredients, and other excipients need to be thoroughly mixed evenly using mixing equipment. Because hydrogel materials have a certain degree of viscosity, they are very easy to adhere to the inner wall of the mixing equipment during the mixing process. If they are not removed in time, it will not only cause material waste, but also affect the mixing quality of subsequent batches of materials. In fact, materials that adhere for too long may deteriorate and contaminate new materials.

[0003] Currently, existing mixing equipment is usually equipped with a simple scraping structure, such as a scraper fixed on the mixing shaft. The rotation of the mixing shaft drives the scraper to scrape off the material on the inner wall. However, this scraping structure has the problem that the gap between the scraper and the inner wall cannot be adjusted. After long-term use, the scraper wears down, causing the gap to increase and the scraping effect to decrease. Therefore, a high-efficiency scraping device for hydrogel patch mixing equipment is proposed to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a high-efficiency scraping device for hydrogel patch mixing equipment, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-efficiency scraping device for a hydrogel patch mixing equipment, comprising a transmission rod and an adjusting rod, wherein the adjusting rod is disposed on both sides of the transmission rod, two sets of sliders are slidably mounted on the outer side of the transmission rod, a bidirectional screw is threaded on one side of the slider, and hinge rods are hinged to the surfaces on both sides of the slider, one end of the hinge rod is hinged to the surface of the adjusting rod, a spring-loaded assembly is disposed inside the adjusting rod, one end of the spring-loaded assembly is connected to a scraper, and a locking assembly is connected to the bottom end of the transmission rod.

[0006] Preferably, the rebound assembly includes a baffle, a slide rod, and a spring. The slide rod slides through the interior of the adjusting rod. The spring is located on the outer side of one end of the slide rod and abuts against the surface of the scraper side. The baffle is installed at the other end of the slide rod and is located on the outer side of the adjusting rod.

[0007] Preferably, a bearing is installed at the bottom of the transmission rod, a support plate is installed on the outer side of the lower end of the transmission rod, and the lower end of the bidirectional screw is rotatably mounted on the upper surface of the support plate.

[0008] Preferably, the engaging assembly includes a sleeve and a block. The block is fixedly installed at the bottom of the inner wall of the mixing device, and the sleeve is fixedly installed on the lower surface of the bearing. The inside of the sleeve engages with the block.

[0009] Preferably, the outer surface of the transmission rod and the outer surface of the slide rod are respectively equipped with a first limiting strip and a second limiting strip, and can slide inside the slider and the adjusting rod respectively. The inner walls of the slider, the adjusting rod and the mounting plate are all provided with limiting grooves that are adapted to the first limiting strip and the second limiting strip.

[0010] Preferably, a quick-release sleeve is fixedly connected to the upper end of the transmission rod, the quick-release sleeve is adapted to engage with the locking pin of the mixing equipment, an mounting plate is fixedly installed on one side of the adjusting rod, and the slide rod is slidably disposed inside the mounting plate.

[0011] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model can quickly engage with the clamping post of the mixing equipment through the quick-release sleeve, which facilitates the installation and disassembly of the device. Rotating the bidirectional screw can drive two sets of sliders to move in opposite directions. The adjusting rod is pushed by the hinge rod to move, thereby driving the scraper to abut against the inner wall of the mixing equipment. The distance between the scraper and the inner wall can be adjusted to avoid the scraping effect being affected by the increased gap caused by scraper wear.

[0012] 2. When the transmission rod rotates, it drives the scraper to rotate and scrape off the material on the inner wall. When the inner wall of the mixing equipment is uneven, the spring pushes the scraper, causing the slide bar to slide in the mounting plate, ensuring that the scraper is always in contact with the inner wall, improving the comprehensiveness and effect of scraping, reducing material waste, and preventing material deterioration and contamination of subsequent materials.

Detailed Implementation

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Please refer to Figure 1-3 As shown, this utility model provides a high-efficiency scraping device for hydrogel patch mixing equipment, including a transmission rod 2 and an adjusting rod 3. The adjusting rod 3 is arranged on both sides of the transmission rod 2. Two sets of sliders 4 are slidably installed on the outer side of the transmission rod 2. One side of the slider 4 has a bidirectional screw 8 in the internal thread. The surfaces on both sides of the slider 4 are hinged with hinge rods 6. One end of the hinge rod 6 is hinged to the surface of the adjusting rod 3. The adjusting rod 3 is provided with a spring-loaded component. One end of the spring-loaded component is connected to a scraper 12. The bottom end of the transmission rod 2 is connected to a locking component.

[0016] Specifically, this utility model allows for quick engagement with the clamping post of the mixing equipment via the quick-release sleeve 1, facilitating installation and disassembly. Rotating the bidirectional screw 8 drives two sets of sliders 4 to move in opposite directions. The hinge rod 6 pushes the adjusting rod 3 to move, thereby causing the scraper 12 to press against the inner wall of the mixing equipment. The distance between the scraper 12 and the inner wall can be adjusted to prevent the scraping effect from being affected by increased gap due to wear of the scraper 12. When the transmission rod 2 rotates, it drives the scraper 12 to rotate and scrape the material on the inner wall. When the inner wall of the mixing equipment is uneven, the spring 11 pushes the scraper 12, causing the slide rod 10 to slide within the mounting plate 7, ensuring that the scraper 12 is always in contact with the inner wall, improving the comprehensiveness and effectiveness of scraping, reducing material waste, and preventing material deterioration and contamination of subsequent materials.

[0017] The rebound assembly includes a baffle 9, a slide rod 10, and a spring 11. The slide rod 10 slides through the inside of the adjusting rod 3. The spring 11 is located on the outside of one end of the slide rod 10 and abuts against the surface of one side of the scraper 12. The baffle 9 is installed at the other end of the slide rod 10 and is located on the outside of the adjusting rod 3. When the inner wall of the mixing equipment is uneven, the scraper 12 drives the slide rod 10 and the second limiting strip 17 to slide inside the adjusting rod 3 and the mounting plate 7, while simultaneously squeezing the spring 11 at one end, so that the scraper 12 can always be in contact with the inner wall of the mixing equipment.

[0018] Specifically: a bearing 5 is installed at the bottom of the transmission rod 2, a support plate 13 is installed on the outer side of the lower end of the transmission rod 2, and the lower end of the bidirectional screw 8 is rotatably installed on the upper surface of the support plate 13. The bearing 5 facilitates the rotation of the transmission rod 2, and the support plate 13 provides support for the bidirectional screw 8.

[0019] The engaging assembly includes a sleeve 15 and a block 14. The block 14 is fixedly installed at the bottom of the inner wall of the mixing equipment, and the sleeve 15 is fixedly installed on the lower surface of the bearing 5. The inside of the sleeve 15 engages with the block 14. The sleeve 15 and the block 14 can limit the movement of the device and prevent it from rotating.

[0020] Wherein: the outer surface of the transmission rod 2 and the outer surface of the slide rod 10 are respectively equipped with a first limiting strip 16 and a second limiting strip 17, and can slide inside the slider 4 and the adjusting rod 3 respectively. The inner walls of the slider 4, the adjusting rod 3 and the mounting plate 7 are all provided with limiting grooves that are adapted to the first limiting strip 16 and the second limiting strip 17. Through the first limiting strip 16 and the second limiting strip 17, the slider 4 and the slide rod 10 can be limited to prevent rotational deviation.

[0021] Among them: the upper end of the transmission rod 2 is fixedly connected to the quick-release sleeve 1, which is adapted to engage with the clamping column of the mixing equipment; the side of the adjusting rod 3 is fixedly installed with the mounting plate 7; the slide rod 10 is slidably set inside the mounting plate 7; the quick-release sleeve 1 can quickly engage with the clamping column of the mixing equipment, which is convenient for the installation and disassembly of the device; the mounting plate 7 can increase the stability of the slide rod 10 when it moves.

[0022] Working Principle: This utility model is a high-efficiency scraping device for hydrogel patch mixing equipment. First, the device is placed inside the mixing equipment. Then, the quick-release sleeve 1 is engaged with its matching locking post. Next, the bidirectional screw 8 is rotated, causing two sets of sliders 4 to move opposite each other on the surface of the transmission rod 2. The movement of the sliders 4 causes one end of the hinge rod 6 to move, which in turn pushes the adjusting rod 3 to move. The movement of the adjusting rod 3 causes the installed scraper 12 to move accordingly and press against the inner wall of the mixing equipment. Then, the rotating motor is started to drive the quick-release sleeve 1 and the transmission rod 2 to move together. Rotating rod 2 drives sliding block 4 to rotate, which in turn drives multiple sets of scrapers 12 to rotate, thereby scraping off the material on the inner wall of the mixing equipment. When the inner wall of the mixing equipment is uneven, the scraper 12 drives sliding rod 10 and second limit bar 17 to slide inside adjusting rod 3 and mounting plate 7, while simultaneously squeezing spring 11 at one end, so that the scraper 12 can always be in contact with the inner wall of the mixing equipment. By rotating bidirectional screw 8 to adjust the distance between the two sets of sliding blocks 4, the distance between the scraper 12 and the inner wall of the mixing equipment can be adjusted.
