Description

Technical Field

[0001] The present invention relates to the technical field of dressing coating equipment, and in particular to a dressing coating equipment for wound care and a use method thereof. Background Art

[0002] Medical dressings are medical supplies used for covering, protecting and treating wounds, and play an important role in the wound healing process. They are prepared by coating a drug slurry on a long strip of cloth, then drying the drug slurry on the cloth with a hot air blower, and then cutting the cloth coated with the drug slurry into pieces, such as a slurry coating device for medical dressing production disclosed in Application No. 202010447622.4, or directly coating the drug slurry on the cut cloth and then drying it. The prior art places the drug slurry in a hot melt dispensing machine, controls the moving cloth to spray the drug slurry at regular intervals through a PLC, and then presses the lump-shaped drug slurry into a circular thin layer through a circular pressing plate. In actual application of the dressing, it is convenient to apply it on the wound surface and is more conducive to the absorption of the wound. However, since the circular pressing plate directly presses the drug slurry, the thickness of the circular thin layer will be uneven and the circular layer will be irregular, resulting in the dressing actually produced being not conducive to fitting the wound or not conducive to the absorption of the drug by the wound. Summary of the invention

[0009] The method of use includes the following steps: Step 1: Place the fabric in the guide mechanism; Step 2: Start the driving mechanism, which drives the guide mechanism to move intermittently to the right. Each time the guide mechanism moves to the right once and then stops, the previous piece of cloth in the guide mechanism is just below the nozzle. According to the timing setting of the hot melt dispensing machine, the drug slurry inside is sprayed onto the cloth through the nozzle at this time. While step 3 and step 2 are being carried out, the driving mechanism also drives the coating mechanism to rise and fall while rotating. When the driving mechanism drives the guide mechanism to move one step to the right, the next piece of cloth reaches directly under the nozzle, and the cloth originally sprayed with the drug slurry moves one step to the right to reach directly under the coating mechanism. The coating mechanism slowly descends and rotates slowly to spread the ball-shaped drug slurry on the cloth evenly in the direction of circular rotation.

[0010] The present invention has the following advantages: the driving mechanism is started, and the driving mechanism drives the guide mechanism to intermittently move to the right. Whenever the guide mechanism moves to the right once and then stops, the previous piece of cloth in the guide mechanism is just located directly below the nozzle. According to the timing setting of the hot melt glue dispenser, the medicine slurry inside is sprayed onto the cloth through the nozzle at this time. The driving mechanism also drives the coating mechanism to rise and fall while rotating. When the driving mechanism drives the guide mechanism to move one step forward to the right, the next piece of cloth reaches directly below the nozzle, and the cloth originally sprayed with the medicine slurry moves one step to the right to reach directly below the coating mechanism. The coating mechanism slowly descends and rotates, so that The ball-shaped drug slurry on the cloth is evenly spread in the direction of circular rotation. During this process, the hot air blower blows downward on the spread drug slurry to make it dry and solidify, until the drug slurry is evenly spread into a thin, regular circular layer to complete the dressing coating. The present invention not only realizes the continuous pushing and coating of pieces of cloth one by one, but also flattens and rounds the drug slurry and coats it on the cloth, making the flattened slurry more uniform and the formed drug slurry layer more round. At the same time, in the process of flattening and rounding, since the drug slurry is evenly evacuated, the hot air originally used by the hot air blower to dry the drug slurry can dry the drug slurry faster, thereby improving production efficiency.

The rotating rod 37 is fixed in the bearing 36 and can rotate in the bearing 36. A rotating column 38 is provided on the rotating rod 37. A spiral groove 39 is provided on the rotating column 38. An L-shaped lever 40 is movably provided in the spiral groove 39. The L-shaped lever 40 can slide in the spiral groove 39 to limit the spiral groove 39. One end of the L-shaped lever 40 is fixed on the fixed plate 25. A vertical plate 41 is provided at the bottom of the rotating column 38. A scraper 42 is provided on the vertical plate 41. When the rotating rod 37 and the rotating column 38 are lowered with the lifting column 33, the trajectory of the spiral groove 39 is limited by the L-shaped lever 40, so that the rotating column 38 rotates, and the rotating column 38 drives the rotating rod 37 to rotate in the bearing 36. The rotating column 38 also drives the vertical plate 41 and the scraper 42 to rotate.

[0020] The method of use is as follows: place the cloth in the placement slot 11, start the hot air blower 7, which is always in operation after being turned on, and continuously blows hot air downward through the air outlet, start the motor 13, the motor 13 drives the first connecting rod 15 to rotate counterclockwise, the first connecting rod 15 drives the second connecting rod 16 to rotate, and the other end of the second connecting rod 16 rotates on the fixed shaft 21. Since the block 19 is limited in the slot 18, the second connecting rod 16 pushes the fixed shaft 21 to move rightward while rotating, and the fixed shaft 21 drives the moving plate 20, and the moving plate 20 drives the block 19 in the slot 1 8 moves to the right, and at the same time, the rotating shaft 22, crank 23 and limiting shaft 24 on the moving plate 20 also move to the right. Since a small part of the bottom of the crank 23 extends inside the placement groove 11, and the left part of the crank 23 is blocked by the limiting shaft 24, the crank 23 abuts against the right end of the placement groove 11 when moving to the right and pushes the placement groove 11 to the right. The placement groove 11 drives the pushing plate 10 to slide to the right in the guide groove 9. When the pushed placement groove 11 is located directly below the nozzle 5, the first connecting rod 15 rotating counterclockwise drives the second connecting rod 16 to move to the left, and the second connecting rod 16 drives the moving plate 20. The crank 23 moves to the left. When the crank 23 moves to the left end of the placement slot 11, since the right part of the crank 23 is not limited by the limit shaft 24, when the left part of the crank 23 touches the left end of the placement slot 11, the crank 23 continues to move to the left, so the crank 23 rotates counterclockwise and then leaves the placement slot 11. At this time, the hot melt glue dispenser 4 is turned on according to the set time program, and the drug slurry inside it is sprayed downward through the nozzle 5 and sprayed on the cloth in the placement slot 11 facing it, and the crank 23 moves to the left to the upper part of the push plate 10. In this process, there is no push plate 10. The feeding plate 10 pushes, so the pushing plate 10 is in a stationary state during this process, until the crank 23 slides on the pushing plate 10 to another placement slot 11 on the left, and the hot melt glue dispenser 4 stops spraying the drug slurry according to the set time. When the crank 23 reaches another placement slot 11 on the left, the first connecting rod 15 drives the second connecting rod 16 to move to the right, so that the crank 23 pushes the other placement slot 11 on the left to the right again, and the cloth sprayed with the drug slurry in the placement slot 11 on the right moves to the right side with this placement slot 11 and is located directly below the rotating column 38; During the above steps, the motor 13 synchronously drives the driving pulley 14 to rotate. Under the action of the belt 8, the driven pulley 27 rotates on the connecting shaft 26, and the driven pulley 27 drives the eccentric shaft 28 and the eccentric wheel 29 to rotate. The circular groove 30 on the eccentric wheel 29 also rotates with the eccentric wheel 29, and the limiting rod 34 is slidably arranged in the circular groove 30, so that the limiting rod 34 is driven by the circular groove 30 to make an upward movement first, and the limiting rod 34 drives the lifting column 33 to make an upward movement in the limiting sleeve 32. In the steps described in the above text, when the crank 23 starts to move to the left again, the pushing plate 10 and all the placement slots 11 are in a stationary state again. Since the motor 13 is always in a rotating state, as the eccentric wheel 29 always rotates eccentrically, the placement slot 11 on its lower side is in a stationary state during this period of time, the trajectory of the rotation of the circular groove 30 drives the limiting rod 34 to move downward, and the limiting rod 34 drives the lifting column 33 in the limiting sleeve 32. The lifting column 33 drives the horizontal plate 35, the bearing 36, the rotating rod 37, the rotating column 38, the vertical plate 41 and the scraper 42 to descend together. When the rotating column 38 descends, the trajectory of the spiral groove 39 is limited by the L-shaped lever 40, so that the rotating column 38 rotates, and the rotating column 38 drives the rotating rod 37 to rotate in the bearing 36. The rotating column 38 also drives the vertical plate 41 and the scraper 42 to rotate. The scraper 42 descends and rotates, and the lump-shaped drug slurry on the cloth in the placement groove 11 is removed from the top to the bottom. The lower variable speed rotates while spreading the coating, so that the drug slurry on the cloth is evenly flattened and regularly rounded. During this flattening and rounding process, the drug slurry is dried by the hot air blown down by the hot air blower 7, and the drying speed is faster. The spreading of the drug slurry on the cloth is completed, making it a dressing. After the coating of the dressing is completed, when the crank 23 pushes the next placement slot 11 to the right again, the scraper 42 also moves upward with the rotation of the eccentric wheel 29 and leaves the placement slot 11 where it is.

[0021] The present invention is simple to operate, convenient to use, and suitable for comprehensive promotion and application. Although the embodiments of the present invention have been shown and described, it is understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
