Description

Technical Field

[0001] The utility model relates to the technical field of medical dressings, in particular to a medical dressing coating device. Background Art

[0002] Medical dressings are wound dressings, medical materials used to cover sores, wounds or other lesions, mainly including natural gauze, synthetic fiber dressings, polymer film dressings, foamed polymer dressings, hydrocolloid dressings, alginate dressings, etc. In the production process of medical dressings, a drug slurry is often first coated on the dressing, so that when the patient bandages the wound, the medical dressing promotes rapid healing of the patient's wound and helps the patient recover quickly. At present, the coating device usually needs to coat the slurry on the dressing cloth piece by piece to facilitate the subsequent cutting of the dressing. However, when the coating device cooperates with the conveying component to move the dressing, the slurry is easy to spill on the dressing, resulting in poor quality of the dressing cut out later.

[0003] In order to solve the above problems, the utility model patent with authorization announcement number CN220425787U discloses a slurry coating device for medical dressing production. The device is provided with a coating box, a baffle, a first cylinder and a feed pipe. The first cylinder can drive the baffle to move quickly in the coating box, that is, the baffle can be quickly opened to allow the slurry to flow out of the through hole, or the baffle can be quickly closed to block the through hole so that the slurry cannot flow out. When the slurry is coated piece by piece on the moving coating cloth, the slurry will not drip on other positions on the dressing cloth, thereby improving the yield rate of the coating device operation.

[0004] However, when the device is used, the slurry is sprayed out from the coating box during coating, the coating range of the slurry is inconvenient to control, and the coating amount of the slurry cannot be well controlled, which reduces the processing quality of the dressing and cannot meet the use requirements well.

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Example: See Figures 1 to 4 A medical dressing coating device comprises: a coating platform 1, a coating nozzle 12, the lower end of the coating nozzle 12 is also provided with an anti-overflow ring 121, a coating frame 11 is installed on the coating platform 1; a lifting mechanism 3 is installed on the coating frame 11, used to drive the coating nozzle 12 to rise and fall; a moving mechanism 2 is installed on the coating platform 1, used to drive the dressing cloth to move; a coating mechanism 4 is installed on the coating frame 11, used to apply slurry to the dressing cloth.

[0023] The working principle of the utility model is as follows: when in use, the dressing cloth is placed on the moving mechanism 2, and then the dressing cloth is transported to the bottom of the coating nozzle 12 by the moving mechanism 2, and then the coating nozzle 12 is driven downward by the lifting mechanism 3, so that the anti-overflow ring 121 at the lower end of the coating nozzle 12 is pressed on the dressing cloth, and then the slurry is injected into the anti-overflow ring 121 by the coating mechanism 4, so as to complete the coating work. By setting the anti-overflow ring 121, the coating range can be limited, and at the same time, the coating mechanism 4 can perform quantitative coating, thereby improving the coating quality and better meeting the use requirements.

[0024] As a further solution, the lifting mechanism 3 includes a lifting electric push rod 31 installed on the coating rack 11, the telescopic end of the lifting electric push rod 31 passes through the coating rack 11 and is fixed with a lifting seat 33, and a lifting guide rod 32 is also slidably inserted on the coating rack 11, and the lower end of the lifting guide rod 32 is fixedly connected to the upper end of the lifting seat 33.

[0025] The working principle of the lifting mechanism 3 is: the lifting electric push rod 31 is extended to push the lifting seat 33 downward, so that the coating nozzle 12 at the lower end of the lifting seat 33 is close to the dressing cloth. After the anti-overflow ring 121 at the lower end of the coating nozzle 12 is in contact with the dressing cloth, the lifting electric push rod 31 stops moving downward and the coating work can be carried out.

[0026] As a further solution, the moving mechanism 2 includes a moving slider 24 slidably mounted on the coating table 1, a moving slide 25 is mounted on the upper end of the moving slider 24, a placement groove 251 for placing dressing cloth is opened on the upper end of the moving slide 25, and a pair of moving mounting seats 21 are also installed at the lower end of the coating table 1, a moving screw 23 is rotatably mounted between the moving mounting seats 21, the moving slide 25 is threadedly mounted on the moving screw 23, and a moving motor 22 is also installed at the end of the moving mounting seat 21, and the output end of the moving motor 22 is drivingly connected to the shaft end of the moving screw 23. In this embodiment, a pick-up and placement notch 252 is also opened at the upper end of the moving slide 25 corresponding to each placement groove 251. By setting the pick-up and placement notch 252, the taking and placement of the dressing cloth is facilitated.

[0027] The working principle of the moving mechanism 2 is: when in use, place the dressing cloth piece into the corresponding placement groove 251, start the moving motor 22, and drive the moving screw 23 to rotate through the moving motor 22, thereby driving the moving slider 24 threaded on the moving screw 23 to move, thereby realizing the movement of the moving slide 25, and the moving slide 25 can be moved left and right by the forward and reverse rotation of the moving motor 22, thereby transferring the dressing cloth piece to the bottom of the coating nozzle 12, which is convenient for coating work.

[0028] As a further solution, the coating mechanism 4 includes a coating tank 41 installed on the coating rack 11, a tank cover 45 is installed on the upper end of the coating tank 41, and a coating electric push rod 44 is installed on the upper end of the tank cover 45, and the telescopic end of the coating electric push rod 44 passes through the tank cover 45 and is fixedly connected to a coating piston 47 slidably installed in the coating tank 41; a storage box 46 is also installed on the coating platform 1, and the storage box 46 is connected to the coating tank 41 through a feed pipe 42, and a feed valve 43 is also installed on the feed pipe 42, and a discharge pipe 48 is also installed at the lower end of the coating tank 41, and the discharge pipe 48 is connected to the coating nozzle 12 at the lower end of the lifting seat 33, and a discharge valve 49 is also installed on the discharge pipe 48. In this embodiment, the discharge pipe 48 is a bent hose, which is convenient for extension, and when the coating nozzle 12 moves down, it can better transport materials. In this embodiment, the discharge valve 49 and the feed valve 43 are both solenoid valves.

[0029] The working principle of the coating mechanism 4 is: during coating, first open the feed valve 43 and close the discharge valve 49. At this time, the coating electric push rod 44 contracts and pulls the coating piston 47 upward, thereby generating negative pressure in the coating tank 41, and the slurry in the storage box 46 can be sucked into the coating tank 41 through the feed pipe 42. Then, the feed valve 43 is closed, and the discharge valve 49 is opened. The coating electric push rod 44 extends and pushes the coating piston 47 downward, and the slurry can be transported to the coating nozzle 12 through the discharge pipe 48, and then sprayed out for coating. By controlling the extension and contraction amount of the coating electric push rod, the feed amount and discharge amount each time can be controlled, thereby achieving quantitative coating, which can improve the coating quality and better meet the use requirements.
