Description

Technical Field

[0001] This utility model relates to the field of chitosan dressing processing technology, and in particular to an automatic coating and forming device for chitosan dressings. Background Technology

[0002] Currently, chitosan dressings are widely used in medical dressing production due to their excellent biocompatibility and healing-promoting properties. Existing chitosan dressing spraying equipment mostly uses fixed nozzles to directly spray the solution onto a rotating roller or nonwoven fabric surface. Due to the limited number of nozzles and fixed spray angle, localized accumulation or dry spraying easily occurs during the spraying process, resulting in uneven coating thickness. Furthermore, the sprayed chitosan solution lacks an effective smoothing or dispersing structure on the roller surface; its high fluidity easily forms streaks or wavy accumulations as the roller rotates, affecting the final dressing's smoothness and adhesion quality. While some equipment improves uniformity by increasing the number of nozzles or adjusting the spray pressure, it still cannot achieve automatic smoothing after spraying, resulting in poor coating consistency and insufficient product stability. This uneven coating problem not only affects the appearance of the dressing but also adversely impacts its breathability, adsorption properties, and biocompatibility, limiting the widespread application of chitosan dressings in the medical field.

[0003] In view of this, the present invention proposes an automatic chitosan dressing coating and forming device to solve the problems existing in the prior art. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing an automatic chitosan dressing coating and molding device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An automatic chitosan dressing coating forming device includes a coating table equipped with a conveying roller mechanism. An inverted U-shaped frame is mounted on the coating table, and a coating roller is rotatably connected inside the inverted U-shaped frame. A drive motor is mounted at one end of the coating roller. A T-shaped pipe is fixedly connected to the top of the inverted U-shaped frame, and multiple application heads are evenly spaced on the bottom outer wall of the T-shaped pipe. A conveying hose is mounted on the top of the T-shaped pipe. An inverted U-shaped frame two is fixedly connected to one side outer wall of the inverted U-shaped frame, and multiple rotating shafts are rotatably connected at evenly spaced on the top of the inverted U-shaped frame two. A swinging smoothing scraper is fixedly connected to the bottom end of each rotating shaft. Each swinging smoothing scraper corresponds to one application head. A drive mechanism is mounted on the top outer wall of the inverted U-shaped frame two, enabling the multiple swinging smoothing scrapers to swing synchronously back and forth.

[0007] Furthermore, the driving mechanism includes two sliders, which are slidably connected to the top outer wall of the inverted U-shaped frame, and a rack is fixedly connected between the two sliders, with multiple gears meshing on one side of the rack.

[0008] Furthermore, each of the gears is fixedly connected to the top outer wall of the corresponding rotating shaft, and one of the sliders is provided with an electric telescopic rod II, which is fixedly connected to the top outer wall of the inverted U-shaped frame II.

[0009] Furthermore, two mounting brackets are symmetrically fixedly connected to the top outer wall of the coating table, and each mounting bracket is equipped with an electric telescopic rod. The telescopic ends of the electric telescopic rods are fixedly connected to the top outer wall of the inverted U-shaped frame.

[0010] Furthermore, two electric tensioning push rods are symmetrically arranged on one side of the outer wall of the top of the coating table, and the telescopic ends of the two electric tensioning push rods are fixedly connected to lifting blocks, and a tensioning roller is fixedly connected between the two lifting blocks.

[0011] Furthermore, a mounting frame three is provided on one side of the tension roller, and a dust suction pipe is fixedly connected to the top of the mounting frame three, with a dust suction hood provided at one end of the dust suction pipe.

[0012] Furthermore, a vacuum cleaner is provided at the other end of the suction pipe, and the vacuum cleaner is fixedly connected to the outer wall of the coating table.

Detailed Implementation

[0022] The technical solution of this utility model will be further described in detail below with reference to specific embodiments.

[0023] Example 1: Refer to Figures 1-4An automatic chitosan dressing coating forming device includes a coating table 1 equipped with a conveying roller mechanism 2. An inverted U-shaped frame 3 is mounted on the coating table 1, and a coating roller 10 is rotatably connected inside the inverted U-shaped frame 3. A drive motor 14 is mounted at one end of the coating roller 10. A three-way pipe 12 is fixedly connected to the top of the inverted U-shaped frame 3, and multiple coating heads 13 are evenly spaced on the bottom outer wall of the three-way pipe 12. A conveying hose 4 is mounted at the top of the three-way pipe 12. A conveying hose 4 is fixedly connected to one side of the outer wall of the inverted U-shaped frame 3. The inverted U-shaped frame 11 has multiple rotating shafts 20 equidistantly connected to its top. Each shaft 20 has a fixedly connected oscillating smoothing scraper 19 at its bottom. Each oscillating smoothing scraper 19 corresponds to a coating head 13. A drive mechanism is provided on the outer top wall of the inverted U-shaped frame 11, enabling the multiple oscillating smoothing scrapers 19 to oscillate synchronously. The nonwoven fabric requiring chitosan coating is conveyed via the conveying roller mechanism 2 on the coating table 1. The conveying hose 4 connects to the external chitosan conveying... The equipment for applying chitosan dressings is connected to a conveying hose 4 to a three-way tube 12 during use. The dressing is then sprayed out through multiple applicator heads 13 at the bottom of the three-way tube 12, thus applying the chitosan dressing to the coating roller 10. Simultaneously, a drive motor 14 rotates the coating roller 10. During this process, the drive mechanism on the inverted U-shaped frame 11 is activated, causing multiple rotating shafts 20 on the inverted U-shaped frame 11 to rotate cyclically, thereby causing each rotating shaft... The oscillating smoothing scraper 19 at the bottom of the coating roller 10 oscillates synchronously. There is a gap between the oscillating smoothing scraper 19 and the coating head 13. Since the oscillating smoothing scraper 19 corresponds one-to-one with the coating head 13, when the coating head 13 sprays the chitosan dressing onto the coating roller 10, the synchronously oscillating smoothing scrapers 19 can smooth the chitosan dressing, so that the chitosan dressing is evenly distributed on the coating roller 10. Thus, the coating roller 10 can evenly coat the chitosan dressing onto the nonwoven fabric, greatly improving the product quality.

[0024] As a further embodiment of this utility model, the driving mechanism includes two sliders 15, which are slidably connected to the top outer wall of the inverted U-shaped frame 11, and a rack 16 is fixedly connected between the two sliders 15. Multiple gears 17 are meshed on one side of the rack 16.

[0025] As a further improvement in this utility model, each gear 17 is fixedly connected to the top outer wall of the corresponding rotating shaft 20. One of the sliders 15 is provided with an electric telescopic rod 18 on one side, and the electric telescopic rod 18 is fixedly connected to the top outer wall of the inverted U-shaped frame 11. The electric telescopic rod 18 pushes the slider 15 connected to it to move back and forth, and can move the rack 16 synchronously. Since the gear 17 at the top of each rotating shaft 20 meshes with the rack 16, multiple rotating shafts 20 can be synchronously rotated back and forth.

[0026] As a further improvement in this utility model, two mounting brackets 6 are symmetrically fixedly connected to the top outer wall of the coating table 1, and each of the two mounting brackets 6 is equipped with an electric telescopic rod 5. The telescopic ends of the electric telescopic rods 5 are fixedly connected to the top outer wall of the inverted U-shaped frame 3. The position and height of the inverted U-shaped frame 3 can be adjusted by the electric telescopic rods 5, thus making it suitable for different coating operations.

[0027] As a further improvement in this utility model, two electric tensioning push rods 9 are symmetrically arranged on the outer wall of one side of the top of the coating table 1, and the telescopic ends of the two electric tensioning push rods 9 are fixedly connected to lifting blocks 8. A tensioning roller 7 is fixedly connected between the two lifting blocks 8. The position and height of the tensioning roller 7 can be adjusted by the electric tensioning push rods 9, thereby ensuring that the nonwoven fabric being coated is in a taut state, thereby improving product quality.

[0028] Working principle: The nonwoven fabric to be coated with chitosan dressing is conveyed by the conveying roller mechanism 2 on the coating table 1. The conveying hose 4 is connected to an external device for conveying chitosan dressing. In use, the device conveys the chitosan dressing through the conveying hose 4 to the three-way pipe 12, and then sprays it out through multiple coating heads 13 at the bottom of the three-way pipe 12, thus spraying the chitosan dressing onto the coating roller 10. At the same time, the drive motor 14 causes the coating roller 10 to rotate. During this process, the drive mechanism on the inverted U-shaped frame 11 is also activated, enabling the inverted U-shaped frame 11 to rotate. Multiple rotating shafts 20 on the frame 2 11 rotate cyclically, causing the oscillating smoothing scraper 19 at the bottom of each rotating shaft 20 to oscillate synchronously. There is a gap between the oscillating smoothing scraper 19 and the coating roller 10. Since the oscillating smoothing scraper 19 corresponds one-to-one with the coating head 13, when the coating head 13 sprays chitosan dressing onto the coating roller 10, the synchronously oscillating smoothing scrapers 19 can smooth the chitosan dressing, making the chitosan dressing evenly distributed on the coating roller 10. Thus, the coating roller 10 can evenly coat the chitosan dressing onto the nonwoven fabric, greatly improving product quality.

[0029] Example 2: Refer to Figure 5 An automatic coating and forming device for chitosan dressings, compared with Example 1, has an installation frame 24 on one side of the tension roller 7, and a dust suction pipe 21 is fixedly connected to the top of the installation frame 24, with a dust suction cover 23 at one end of the dust suction pipe 21.

[0030] As a further improvement in this utility model, a vacuum cleaner 22 is provided at the other end of the suction pipe 21, and the vacuum cleaner 22 is fixedly connected to the outer wall of the coating table 1. When the chitosan dressing is applied, the vacuum cleaner 22 is started simultaneously. The vacuum cleaner 22 can generate a huge suction force through the suction pipe 21, thereby removing the garbage and impurities on the non-woven fabric to be sprayed and avoiding any residual garbage and impurities.

[0031] Working principle: When the chitosan dressing is applied, the vacuum cleaner 22 is started simultaneously. The vacuum cleaner 22 can generate a huge suction force through the vacuum pipe 21 and the vacuum hood 23, thereby removing the garbage and impurities on the non-woven fabric to be sprayed and avoiding the presence of residual garbage and impurities.

[0032] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
