Description

Technical Field

[0001] This utility model relates to the field of polyurethane foam dressing production technology, and in particular to a foaming device for producing polyurethane foam dressings. Background Technology

[0002] Polyurethane foam dressing is a type of medical functional dressing developed based on polyurethane material. It is mainly used for wound care. In the production of polyurethane foam dressing, a foaming device is required to foam it.

[0003] Traditional foaming devices typically use a discharge pipe for material feeding. However, the discharge pipe is slow and prone to clogging, making it inconvenient to feed materials. Furthermore, during the feeding process, raw materials adhere to the inner wall of the foaming cylinder and cannot be cleaned in time, leading to waste. Therefore, these devices have the drawback of being difficult to clean and feed materials, thus failing to meet customer needs.

[0004] Therefore, those skilled in the art have provided a foaming apparatus for the production of polyurethane foam dressings to solve the problems mentioned in the background art. Utility Model Content

A maintenance plate is provided on the front of the drive box 8, and the maintenance plate is fixedly connected to the connection of the drive box 8 by screws.

[0033] In this embodiment: By setting up a foaming cylinder 3, a concave plate 4, a rotating shaft 5, a stirring plate 6, a concave scraper 7, and a driving assembly 13, this utility model can quickly and evenly stir and foam polyurethane foam dressing raw materials and additives. At the same time, the concave scraper 7 can scrape and clean the inner wall of the foaming cylinder 3. By setting up a concave frame 1, a rotating column 2, a driving box 8, an electric cylinder 9, an L-shaped plate 10, a toothed plate 11, and a first gear 12, the foamed polyurethane foam dressing can be poured out. By setting up a heating assembly 14, the foaming cylinder 3 can be preheated. With the above structure, it is convenient to clean and use the material, thereby meeting the customer's needs.

[0034] Example 2:

[0035] Reference Figure 1 , Figure 2 and Figure 3 The heating assembly 14 includes a heating resistance wire 141, which is spirally connected to the connection of the foaming cylinder 3. A protective cover 142 is fixedly installed on the outer surface of the foaming cylinder 3 and outside the heating resistance wire 141.

[0036] In this embodiment: the present invention can heat the foaming cylinder 3 by setting a heating resistance wire 141 and a protective cover 142.

[0037] The implementation principle of this utility model is as follows: When in use, the staff fixes the device in the designated position by using the mounting plate, mounting holes and screws. Then, the staff connects the device to the mains power. Then, when foaming in low temperature weather, the staff starts the external controller of the heating resistance wire 141, so that the heating resistance wire 141 is energized and heated, so that the heating resistance wire 141 conducts heat to the foaming cylinder 3, so that it reaches the required foaming temperature, thereby achieving preheating of the foaming cylinder 3.

[0038] Next, the staff put the polyurethane foam dressing raw material and foaming additive into the inner cavity of the foaming cylinder 3. At the same time, the staff started the external controller of the rotary motor 131, so that the output end of the rotary motor 131 drives the second gear 132 to rotate, the second gear 132 drives the third gear 133 to rotate, the third gear 133 drives the rotating shaft 5 to rotate, so that the rotating shaft 5 drives the stirring plate 6 and the concave scraper 7 to rotate, thereby achieving uniform stirring of the polyurethane foam dressing raw material and foaming additive, so that it can foam evenly and quickly.

[0039] After foaming is complete, when unloading is required, the operator places the storage box in front of the device. Then, the operator activates the external controller of the electric cylinder 9, causing the telescopic end of the electric cylinder 9 to move the L-shaped plate 10 upward. The L-shaped plate 10 then moves the toothed plate 11 upward. As the toothed plate 11 moves upward, it drives the first gear 12 to rotate counterclockwise, which in turn drives the rotating column 2 to rotate counterclockwise. This causes the rotating columns 2 on both sides to slowly rotate the foaming cylinder 3 counterclockwise and tilt it downward, allowing the polyurethane foam dressing inside the foaming cylinder 3 to pour into the inner cavity of the external storage box. At the same time, the rotating shaft 5 drives the concave scraper 7 to rotate, scraping and cleaning the residual material on the inner wall of the foaming cylinder 3. The cleaned polyurethane foam dressing then flows into the inner cavity of the external storage box, thus cleaning and unloading the foaming cylinder 3. This device is simple to operate and easy to clean and unload, meeting the needs of customers.

[0040] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
