Description

Technical Field

[0001] This utility model relates to the field of repair dressing coating technology, and in particular to a coating device for repair dressings. Background Technology

[0002] Repair dressings are medical materials made from natural or synthetic polymers as a matrix, processed using special techniques. They can be directly applied to the surface of wounds to protect them and promote healing. The core objective of these dressings is to create a microenvironment conducive to tissue repair, while reducing the risk of infection and accelerating the wound healing process. During the production of repair dressings, the material needs to be evenly coated onto the surface of the material film; therefore, a coating device for repair dressings is used to achieve this uniform coating process.

[0003] However, the existing equipment has the following shortcomings: when the material film moves on the conveyor belt during use, it is easy for it to tilt, causing deviations during film coating and affecting the accuracy of film coating.

[0004] Therefore, we propose a coating device for repair dressings to address the problems mentioned above. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies where material films tend to shake during coating, making it difficult for equipment to perform the coating process. This invention provides a coating device for repair dressings.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a coating device for repair dressings, comprising a main body, a conveyor belt, a film applicator, a material hopper, and a connecting frame. The conveyor belt is installed on the upper end of the main body. The connecting frame is fixedly connected to the upper surface of the main body. The film applicator is fixedly connected to the upper surface of the connecting frame. The material hopper is fixedly connected to the upper end of the film applicator. A guiding device is fixedly provided on the upper surface of the main body. The guiding device includes a guide plate and a limiting block. The limiting block is fixedly connected to the upper surface of the main body. The guide plate is positioned above the conveyor belt. A moving rod is fixedly connected to the end of the guide plate near the limiting block. The moving rod is slidably connected inside the limiting block. A connecting rod is fixedly connected to the end of the moving rod away from the guide plate. A connecting plate is fixedly connected to the surface of the main body. A limiting hole is formed on the surface of the connecting plate. A first spring is sleeved and connected to the surface of the moving rod.

[0007] Furthermore, one end of the first spring is fixedly connected to the surface of the limiting block, and the end of the first spring away from the limiting block is fixedly connected to the surface of the connecting rod. By setting the limiting block, the moving rod can be limited, reducing the likelihood of the moving rod shaking during use and preventing the guide plate from moving smoothly.

[0008] Furthermore, a limiting plate is fixedly connected to the end of the connecting rod away from the moving rod.

[0009] Furthermore, an insert plate is slidably connected inside the limiting plate, and the insert plate is inserted into the limiting hole. The insert plate is provided to facilitate the limiting of the connecting rod.

[0010] Furthermore, an auxiliary component is fixedly installed at the upper end of the material hopper. The auxiliary component includes a protective cover and a rotating frame. The rotating frame is fixedly connected to the side of the material hopper, and the protective cover is installed at the upper end of the material hopper. A rotating block is fixedly connected to the side of the protective cover. The rotating block is rotatably connected to the interior of the rotating frame. A positioning groove is provided at the end of the protective cover away from the rotating block. A limit rod is fixedly connected to the surface of the material hopper. A positioning plate is slidably connected to the surface of the limit rod. The positioning plate is inserted into the interior of the positioning groove. A fixing block is fixedly connected to the end of the limit rod away from the material hopper. By setting the positioning plate, the protective cover can be limited, reducing the possibility of the protective cover easily shaking on the surface of the material hopper during use.

[0011] Furthermore, a second spring is sleeved and connected to the surface of the limiting rod.

[0012] Furthermore, one end of the second spring is fixedly connected to the surface of the positioning plate, and the other end of the second spring away from the positioning plate is fixedly connected to the surface of the fixing block. The second spring is provided to facilitate the application of a reset force to the positioning plate.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0014] 1. In this utility model, by setting a guiding device, the material film is effectively limited and guided, which plays a guiding role in the material film. This reduces the situation where the material film tends to tilt when moving on the conveyor belt during the use of existing equipment, causing deviations in the film coating process and affecting the accuracy of the film coating. This guiding device can limit the movement of the material film that needs to be coated, making it easier to accurately coat the material film and improving the accuracy of the film coating process.

[0015] 2. In this utility model, by setting auxiliary components, the surface of the material hopper is effectively protected, which plays a role in protecting the material hopper. This reduces the situation where, during the use of existing equipment, due to the poor production environment, some foreign objects can easily enter the material hopper through the feed inlet and contaminate the material inside the hopper, making the material unusable. This auxiliary component can protect the inside of the material hopper and improve the practicality of the equipment. Attached Figure Description

[0023] Please see Figures 1-6 This utility model provides a technical solution: a coating device for repair dressing, including a main body 1, a conveyor belt 2, a film applicator 3, a material hopper 4 and a connecting frame 5. The conveyor belt 2 is installed on the upper end of the main body 1, the connecting frame 5 is fixedly connected to the upper surface of the main body 1, the film applicator 3 is fixedly connected to the upper surface of the connecting frame 5, and the material hopper 4 is fixedly connected to the upper end of the film applicator 3.

[0024] The specific settings and functions of its guide device 6 and auxiliary components 7 will be discussed below.

[0025] In this embodiment: A guide device 6 is fixedly installed on the upper surface of the main body 1. The guide device 6 includes a guide plate 61 and a limiting block 62. The limiting block 62 is fixedly connected to the upper surface of the main body 1. The guide plate 61 is positioned above the conveyor belt 2. The surface of the guide plate 61 is made of a smooth, wear-resistant material, which can reduce the friction between the guide plate and the material film and ensure that the material film can pass smoothly through the guide plate 61. At the same time, the angle and position of the guide plate 61 can be flexibly adjusted according to the width of the material film and the conveying speed, thereby effectively limiting and guiding the material film, ensuring that the material film maintains linear movement during the conveying process, and improving the accuracy of film coating. A moving rod 63 is fixedly connected to one end of the guide plate 61 near the limiting block 62. The moving rod 63 is slidably connected inside the limiting block 62. A connecting rod 66 is fixedly connected to one end of the moving rod 63 away from the guide plate 61. A connecting plate 65 is fixedly connected to the surface of the main body 1. A limiting hole 67 is opened on the surface of the connecting plate 65. A first spring 64 is sleeved and connected to the surface of the moving rod 63.

[0026] Specifically, one end of the first spring 64 is fixedly connected to the surface of the limiting block 62, and the other end of the first spring 64 away from the limiting block 62 is fixedly connected to the surface of the connecting rod 66.

[0027] In this embodiment: by setting the limiting block 62, the moving rod 63 can be limited, which reduces the possibility that the moving rod 63 will shake during use, making it difficult for the guide plate 61 to move smoothly.

[0028] Specifically, the end of the connecting rod 66 away from the moving rod 63 is fixedly connected to a limiting plate 69.

[0029] Specifically, the limiting plate 69 has an insert plate 68 that is slidably connected inside. The insert plate 68 is inserted into the limiting hole 67. The insert plate 68 is provided to facilitate the limiting of the connecting rod 66.

[0030] In this embodiment: An auxiliary component 7 is fixedly installed at the upper end of the material hopper 4. The auxiliary component 7 includes a protective cover 71 and a rotating frame 78. The rotating frame 78 is fixedly connected to the side of the material hopper 4. The protective cover 71 is installed at the upper end of the material hopper 4. A rotating block 77 is fixedly connected to the side of the protective cover 71. The rotating block 77 is rotatably connected to the inside of the rotating frame 78. A positioning groove 73 is opened at the end of the protective cover 71 away from the rotating block 77. A limit rod 74 is fixedly connected to the surface of the material hopper 4. A positioning plate 72 is slidably connected to the surface of the limit rod 74 for positioning. The plate 72 is internally inserted into the positioning groove 73. The end of the limiting rod 74 away from the material hopper 4 is fixedly connected to the fixing block 75. The positioning plate 72 and the positioning groove 73 are matched in shape, and the surface of the positioning plate 72 is finely processed so that it can fit tightly with the positioning groove 73. When the positioning plate 72 is inserted into the positioning groove 73, it can effectively limit the rotation and shaking of the protective cover 71, ensure that the protective cover 71 maintains a stable position on the material hopper 4, and reduce the material inside the material hopper 4 from being disturbed by the outside due to the shaking of the protective cover 71.

[0031] In this embodiment, by setting the positioning plate 72, the protective cover 71 can be limited, which reduces the situation where the protective cover 71 is prone to shaking on the surface of the material hopper 4 when the equipment is in use.

[0032] Specifically, a second spring 76 is sleeved and connected to the surface of the limiting rod 74.

[0033] Specifically, one end of the second spring 76 is fixedly connected to the surface of the positioning plate 72, and the other end of the second spring 76 away from the positioning plate 72 is fixedly connected to the surface of the fixing block 75. The second spring 76 is provided to facilitate the application of a reset spring force to the positioning plate 72.

[0034] Working Principle: When using the equipment, the material to be coated is put into the material hopper 4. The equipment is then started, and the material film passes through the connecting frame 5 via the conveyor belt 2. The coating device 3 then evenly coats the material film surface. Before use, the user moves the insert plate 68 upwards. The insert plate 68 then moves inside the limiting plate 69 and disengages from the limiting hole 67. The connecting rod 66 then moves the moving rod 63 inside the limiting block 62. When the moving rod 63 moves, it compresses the first spring 64, generating elastic force. When the moving rod 63 moves, it moves the guide plate 61. By setting the guide device 6, the material film is effectively limited and guided, which reduces the tendency of the material film to tilt when moving on the conveyor belt 2, causing deviations in the coating process and affecting the coating accuracy. This guide device 6 can limit the movement of the material film to be coated, facilitating accurate coating and improving the coating accuracy of the equipment.

[0035] When the protective cover 71 is opened, the user pulls the positioning plate 72 out of the positioning groove 73. When the positioning plate 72 moves, it compresses the second spring 76 to generate elastic force, and then the protective cover 71 is released from its restraint. Rotating the protective cover 71 drives the rotating block 77 to rotate inside the rotating frame 78, and then the protective cover 71 is released from the surface of the material hopper 4. By setting the auxiliary component 7, the surface of the material hopper 4 is effectively protected, which plays a role in protecting the material hopper 4. This reduces the situation where, due to the poor production environment of the equipment, some foreign objects can easily enter the material hopper 4 through the feed inlet and contaminate the material inside the material hopper 4, making the material unusable. This auxiliary component 7 can protect the inside of the material hopper 4 and improve the practicality of the equipment.
