Description

Technical Field

[0001] The utility model relates to the technical field of sponge processing, in particular to a dressing coating and laminating machine for medical sponge processing. Background Technique

[0002] A dressing refers to a material used to cover or protect a wound, wound surface or surgical incision. Dressings have a wide range of applications in the medical field, mainly used in multiple aspects such as wound care, surgical drapes, sanitary products, etc. According to their materials and uses, dressings can be divided into various types, including natural material types, synthetic material types, medicated dressing types, fixation dressing types, etc.

[0003] In the medical field, medical sponges, as an important dressing material, are widely used in multiple aspects such as wound care, surgical drapes, sanitary products, etc. Their excellent water absorption, air permeability, antibacterial property and good biocompatibility make medical sponges play an irreplaceable role in promoting wound healing and preventing infection.

[0004] When the existing coating and laminating machine performs coating, it usually uses roll coating. The adhesive is applied to the coating roll, and the coating roll rotates to apply the adhesive on the surface of the sponge dressing. However, this coating method makes the adhesive unevenly distributed on the sponge dressing, resulting in poor bonding between the sponge dressing and the substrate and poor production quality. Summary of the Utility Model

[0005] The utility model discloses a dressing coating and laminating machine for medical sponge processing, aiming to solve the technical problem that when the existing coating and laminating machine performs coating, it usually uses roll coating. The adhesive is applied to the coating roll, and the coating roll rotates to apply the adhesive on the surface of the sponge dressing. However, this coating method makes the adhesive unevenly distributed on the sponge dressing, resulting in poor bonding between the sponge dressing and the substrate and poor production quality.

[0006] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0007] A dressing coating and laminating machine for medical sponge processing, including two side plates, a sponge dressing and a substrate, further comprising:

[0008] A coating mechanism, including a first roller rotatably connected between the two side plates. A rubber ring is arranged on the circumferential outer wall of the first roller. A coating roll and a rubber cylinder are arranged on the circumferential outer wall of the rubber ring. The rubber cylinder is arranged between the rubber ring and the coating roll. Uniformly distributed coating grooves are arranged on the circumferential outer wall of the coating roll. Uniformly distributed rubber columns are arranged on the circumferential outer wall of the rubber cylinder. One end of the rubber column is close to the circumferential inner wall of the coating roll;

[0009] A laminating mechanism for laminating the substrate and the sponge dressing.

[0010] With the above solution, the rubber ring, rubber column and rubber cylinder are all made of rubber and have elasticity. The adhesive is applied on the surface of the coating roller and filled in the coating tank. The first rotating roller and the coating roller rotate continuously. The circumferential outer wall of the coating roller fits with the surface of the sponge dressing. After the coating roller is squeezed, the rubber column is compressed, and the rubber column, rubber cylinder and rubber ring are recessed inward, squeezing out the adhesive in the coating tank and applying it on the surface of the sponge dressing, making the coating more uniform. After the coating roller continues to rotate, the rubber ring, rubber cylinder and rubber column rebound, refill the adhesive, and rotate in a cycle for high-precision and uniform coating, improving the quality and consistency of the product, so that the sponge dressing and the substrate are more firmly bonded.

[0011] In a preferred solution, symmetrically distributed first mounting plates are provided at the tops of the two side plates. A mixing cylinder is provided between the two first mounting plates. A feed pipe is provided on the outer wall of one side of the mixing cylinder. A discharge pipe is provided on the circumferential outer wall of the mixing cylinder. Uniformly distributed discharge nozzles are provided on the outer wall of one side of the discharge pipe, and the discharge nozzles correspond to the coating tank.

[0012] In this solution, the adhesive enters the mixing cylinder through the feed pipe, is stirred in the mixing cylinder, and the adhesive is sprayed onto the surface of the coating roller through the discharge nozzles, ensuring that the adhesive is fully stirred and mixed evenly in the mixing cylinder, avoiding the situation of too high or too low local concentration of the adhesive, which affects the effect of the adhesive.

[0013] In a preferred solution, the composite mechanism includes a first composite roller and a second composite roller. The first composite roller is rotatably connected to the inner walls of the opposite sides of the two side plates. Two mounting blocks are provided on the outer wall of one side of the side plate. A threaded rod is rotatably connected between the two mounting blocks. A movable block is sleeved on the outer wall of the threaded rod. The second composite roller is rotatably connected to the outer wall of one side of the movable block.

[0014] In this solution, the sponge dressing and the substrate pass between the first composite roller and the second composite roller to make the sponge dressing and the substrate fit. According to the thickness of the sponge dressing and the substrate, by rotating the threaded rod, the height position of the movable block is adjusted, thereby adjusting the height of the second composite roller and adjusting the distance between the first composite roller and the second composite roller, facilitating the staff to control the pressure well to ensure the composite effect. The magnitude of the force should be appropriate, which can not only ensure the close fit between the sponge dressing and the substrate, but also will not damage the sponge dressing and the substrate, so as to ensure that the sponge dressing and the substrate can be fully fitted to achieve the expected composite effect.

[0015] As can be seen from the above, a dressing coating and composite machine for medical sponge processing includes two side plates, a sponge dressing and a substrate, and further includes:

[0016] Coating mechanism, including a first roller rotatably connected between the two side plates, a rubber ring is arranged on the circumferential outer wall of the first roller, a coating roller and a rubber cylinder are arranged on the circumferential outer wall of the rubber ring, the rubber cylinder is arranged between the rubber ring and the coating roller, uniformly distributed coating grooves are arranged on the circumferential outer wall of the coating roller, uniformly distributed rubber columns are arranged on the circumferential outer wall of the rubber cylinder, and one end of the rubber column is close to the circumferential inner wall of the coating roller;

[0017] Composite mechanism, used to composite the base material and the sponge dressing. The dressing coating and composite machine for medical sponge processing provided by the present invention has the technical effects that the coating roller rotates in a cycle, the coating is more uniform, the high-precision uniform coating improves the quality and consistency of the product, and thus the sponge dressing and the base material are more firmly composite.

The rubber columns 16, the rubber cylinder 17 and the rubber ring 15 are indented inward, extruding the adhesive in the coating grooves 18 and coating it on the surface of the sponge dressing 9, making the coating more uniform. After the coating roller 7 continues to rotate, the rubber ring 15, the rubber cylinder 17 and the rubber columns 16 rebound and refill the adhesive, rotating in a cycle for high-precision and uniform coating, improving the quality and consistency of the product, so that the sponge dressing 9 and the substrate 4 are laminated more firmly.
