Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of scar treatment, and particularly relates to a processing equipment and process of a pressurized silicone sheet. BACKGROUND

[0002] Burns can be caused by a variety of factors, with severity ranging from one to four degrees, with two and three degrees being between one and four degrees. Both burns and abrasions are prone to hypertrophic scars, which are hard and protruding, with pigmentation. Sometimes, debridement is required. Silicone compounds, especially silicone gel, can effectively improve the condition of scar tissue. Although the cause is not fully understood, the effect is recognized and supported by numerous documents for the treatment of hypertrophic scars.

[0003] The silicone gel patch is composed of a silicone bottom layer and an elastic fabric belt. The surface of the silicone bottom layer is coated with silicone, and the elastic fabric belt is covered on the silicone bottom layer to protect the silicone. During processing, a coating device is needed to coat a layer of silicone on the surface of the silicone bottom layer. Through retrieval, a Chinese patent with the publication number CN119186949A discloses a scraper quick-change device, a coating machine material box and a coating machine. The scraper quick-change device includes a scraper replacement bottom plate, a guide device and a scraper fixing plate driving device are arranged on the scraper replacement bottom plate, a scraper fixing plate is arranged on the guide device, a scraper fixing concave position is arranged on the scraper fixing plate, a scraper storage is also arranged on the scraper replacement bottom plate, and a scraper pressure plate driving device is also arranged. The output end of the scraper pressure plate driving device is provided with a scraper pressure plate. The coating machine material box includes the scraper quick-change device. The material box of the coating machine is provided with the scraper quick-change device or the coating machine includes the coating machine material box. The above scheme has the characteristics of simple structure and easy implementation. When applied, it can reduce the operation difficulty and labor cost, improve the production efficiency and production benefit. However, the above scheme still has the following disadvantages in actual use:

[0004] In the use of the above scheme, the worker places the coating in the material box. When the coating layer passes through the material box, the coating naturally adheres to the surface of the coating layer, and finally is scraped flat by the scraper. However, the coating is exposed to the external environment for a long time. Because the coating is exposed to the external environment for a long time, dust in the environment is easily attached to the coating. This will reduce the purity of the coating, and thus affect the surface quality of the coating layer. Problems such as rough, uneven and impurity particles may occur, which reduces the overall quality and performance of the product, and may also affect the normal progress of the subsequent process and have adverse effects on the final appearance and use effect of the product.

[0046] The silicon rubber sheet processing equipment 1 is provided with a coating unit, the coating unit comprises a support assembly and two scraping assemblies, the support assembly comprises two fixed parts 21, the two fixed parts 21 are provided with liftable lifting parts 22, the lifting parts 22 can move up and down relative to the fixed parts 21, the fixed parts 21 are provided with a drive module for driving the lifting parts 22 to move, the specific structure and working principle of the drive module are prior art, the implementation adopts conventional means, and the specific structure and working principle of the drive module are not shown in the figure and will not be described in detail here, the two lifting parts 22 are fixedly provided with mounting plates 23, two rotatable rotating rods 24 are arranged between the two mounting plates 23, chain wheels 25 are fixedly arranged at the two ends of the two rotating rods 24, and the opposite two chain wheels 25 are connected through chains 26, one of the mounting plates 23 is provided with a motor, and the motor is used for driving one of the rotating rods 24 to rotate; when the motor operates, the corresponding rotating rod 24 can be driven to rotate; the two sets of chain wheel 25 and chain 26 transmission structures cooperate with each other, so that the two rotating rods 24 can synchronously rotate;

[0047] The scraping assembly comprises two scraping structures, the two scraping structures are arranged on the two chains 26, each scraping structure comprises two fixed frames 31, the two fixed frames 31 are fixed on the two chains 26 respectively, and the two fixed frames 31 are arranged in opposition, a frame body 32 is fixedly arranged on the two fixed frames 31, a moving plate 33 is slidably arranged on the frame body 32, and a scraper 34 is arranged at one end of the moving plate 33 away from the frame body 32; when the two chains 26 rotate, the frame body 32 can be driven to move through the two fixed frames 31, and the moving plate 33 and the scraper 34 move accordingly; in the movement process of the scraper 34, the silicon rubber paint on the silicon rubber bottom layer can be uniformly scraped on the silicon rubber bottom layer, the coating of the paint is realized, further, the staff can adjust the positions of the two lifting parts 22 to control the distance between the scraper 34 and the silicon rubber bottom layer, so as to control the thickness of the silicon rubber paint;

[0048] On the basis of the above scheme, the scraper 34 can also scrape the silicon rubber paint on the silicon rubber bottom layer into a wave-shaped structure, as shown in Figure 11As shown, compared with the traditional flat silicone coating, the wavy surface forms a regular concave-convex structure, constructing tiny air channels between the adhesive layer and the skin. These channels allow air to circulate freely, reducing the accumulation of sweat and moisture, thereby reducing the feeling of dampness on the skin and avoiding the risk of itching, redness, swelling or infection caused by a long-term closed environment. In addition, when the scar patch is pulled by external force, the elastic deformation of the wavy structure can disperse the stress, reduce local stress concentration, and thus reduce the risk of the adhesive layer falling off. Specifically, the frame 32 and the movable plate 33 are connected by a sliding structure, and the sliding structure includes two sliding openings and two sliders. The two sliding openings are respectively opened at the two ends of the frame 32, and the two sliders are respectively fixed at the two ends of the movable plate 33. The two sliders slide in the two sliding openings, and each slider is connected to the frame 32 by a reset spring. By setting the sliding structure, the movable plate 33 can move on the frame 32. When the movable plate 33 moves, the two sliding openings and the two sliders provide it with a limit, and the setting of the reset spring is used for the automatic reset of the movable plate 33.

[0049] A control assembly is provided on one of the mounting plates 23, and the control assembly includes a plurality of transverse plates 232, each of which is connected to the mounting plate 23 via a first connecting rod 231, and the bottom surface of each transverse plate 232 is a wavy structure, and a plurality of transverse plates 232 are distributed in a linear array, and one of the sliders is arranged opposite to the plurality of transverse plates 232. When the movable plate 33 moves, one of the sliders will contact the bottom surface of the plurality of transverse plates 232, as shown in FIG. Figure 3 As shown, when the slider passes under the horizontal plate 232, the slider will continuously move up and down under the action of the wavy part of the horizontal plate 232, and drive the movable plate 33 to move up and down. Therefore, under the control of the horizontal plate 232, the movable plate 33 can also move up and down in the vertical direction when passing under the horizontal plate 232 while following the movement of the two chains 26. This makes the scraper 34 move up and down intermittently while scraping the silicone. This action can form the surface of the silicone coating as shown in FIG. Figure 11 Regarding the wavy structure shown, it should be noted that by providing a plurality of horizontal plates 232, the silicone coating can be formed into multiple continuous wavy surfaces, which facilitates the subsequent cutting of the silicone base layer. After cutting, for a piece of silicone base layer, the silicone coating at the two ends is a flat surface, while the silicone coating in the middle is a wavy surface. This design not only retains the unique properties of the wavy silicone layer, but also makes it easier for the user to use the flat surfaces at both ends to firmly adhere the silicone base layer to the skin.

[0050] On the basis of the above scheme, the application also has the function of cleaning the excess silica gel on the scraper 34. This design can avoid the accumulation and solidification of residual silica gel coating on the scraper 34, reduce the trouble and difficulty of subsequent cleaning, save labor and time cost, ensure the surface of the scraper 34 clean every time, make the silica gel coating on the bottom layer more accurate and uniform, improve the construction quality, avoid the problem of uneven thickness caused by residual coating, and specifically, the top surface of the moving plate 33 is provided with a mounting groove 35, the scraper 34 slides in the mounting groove 35, the bottom of the mounting groove 35 is provided with an arc-shaped first elastic sheet 36, and the first elastic sheet 36 abuts against the scraper 34. Under the elastic force of the first elastic sheet 36, the scraper 34 always has a tendency to separate from the mounting groove 35. The moving plate 33 is provided with a limiting opening 37 on both sides, and the two limiting openings 37 are in communication with the mounting groove 35. The two ends of the scraper 34 are fixed with a fixed rod 38, and the two fixed rods 38 are respectively slid in the two limiting openings 37. Each fixed rod 38 is connected with the moving plate 33 through a first tension spring 39. The two limiting openings 37 and the two fixed rods 38 provide limiting for the scraper 34 to prevent it from separating from the mounting groove 35, and the first tension spring 39 is used for automatic reset of the scraper 34.

[0051] Each of the frame bodies 32 is provided with a cleaning assembly, the cleaning assembly comprises two rotating shafts 41, and the two rotating shafts 41 are respectively rotatably installed on the two sides of the moving plate 33. Each rotating shaft 41 is fixed with a first scraper 42. The two sides of the moving plate 33 are fixed with a plurality of second elastic sheets 43. The plurality of second elastic sheets 43 on the same side press the corresponding first scraper 42. Under the elastic force of the plurality of second elastic sheets 43, the two first scrapers 42 always have a tendency to abut against the two sides of the scraper 34. The two sides of the moving plate 33 are fixed with a collecting box 44, and the two collecting boxes 44 are respectively opposite to the two first scrapers 42. One of the mounting plates 23 is provided with a guide assembly, the guide assembly is used to control the position of the two scrapers 34, the guide assembly comprises a guide plate 234 and a second connecting rod 233, the guide plate 234 is connected with the mounting plate 23 through the second connecting rod 233, as shown in Figure 10 The guide plate 234 has two inclined parts and a flat part, and the two inclined parts are arranged at the two ends of the flat part.

[0052] In the process of moving along with the two chains 26, the fixed rod 38 on one end of the scraper 34 will be in contact with the guide plate 234 and move under the guidance of the guide plate 234. In this process, the fixed rod 38 will first be in contact with one of the inclined portions and move along the inclined portion, which makes the scraper 34 move downward while moving horizontally and retract into the mounting groove 35. Then, the fixed rod 38 moves along the flat portion, which makes the scraper 34 remain retracted in the mounting groove 35. Finally, when the fixed rod 38 moves to a position opposite the other inclined portion, the scraper 34 is lifted back up under the action of the second spring 43. Therefore, under the guidance of the guide plate 234, the scraper 34 can move up and down when passing through the position opposite the guide plate 234. When the scraper 34 moves downward, the two first scrapers 42 perform scraping actions on both sides of the scraper 34 and scrape off the silicone attached to the blade of the scraper 34, so that the silicone is transferred to the two first scrapers 42, achieving cleaning of the scraper 34. When the silicone accumulated on the two first scrapers 42 increases, the silicone will slide into the two collection boxes 44 under the action of gravity.

[0053] On the basis of the above-mentioned scheme, the present application also has a surplus material collection function in the process of scraping the silicone. In order to ensure that the silicone coating can uniformly cover the silicone bottom layer, the amount of silicone flowing to the silicone bottom layer through the plurality of nozzles 16 needs to be sufficient. When the scraper 34 scrapes the silicone coating, the silicone coating can fully cover the silicone bottom layer. In this case, the excess silicone will overflow from both sides of the silicone bottom layer. The present application designs a surplus material collection assembly for collecting the overflowing silicone. Specifically, the silicone sheet processing equipment 1 is provided with a belt conveyor 5, and the belt conveyor 5 is located between the two fixed portions 21. The belt conveyor 5 is provided with a conveying belt 51. During processing, the silicone bottom layer falls on the conveying belt 51, which can provide support for the silicone bottom layer, so that the scraper 34 can uniformly scrape the silicone on the silicone bottom layer. During the scraping process, the excess silicone overflowing from both sides of the silicone bottom layer will flow onto the conveying belt 51 and move along with the conveying belt 51. The surplus material collection assembly is arranged below the conveying belt 51. The surplus material collection assembly includes a collection box 61, and the opening of the collection box 61 faces upward. A shaft rod 62 is rotatably installed on the collection box 61. A sleeve plate 63 is fixedly connected to the shaft rod 62. A second scraper 64 is fixedly connected to the sleeve plate 63. The second scraper 64 and the collection box 61 are connected by a second tension spring 65. Under the elastic force of the second tension spring 65, the second scraper 64 always has a tendency to adhere to the conveying belt 51. This makes the second scraper 64 scrape off the silicone attached to the surface of the conveying belt 51 and make the silicone fall into the collection box 61, achieving active collection of the excess silicone.

[0054] It is worth mentioning that when the scraper 34 moves to the position of the blade upward, the scraper 34 is cleaned by the cleaning assembly, and the silica gel generated during the cleaning process falls into the two collection boxes 44. When the scraper 34 rotates to the blade downward, the openings of the two collection boxes 44 are also downward, and the silica gel in the two collection boxes 44 falls off and falls onto the conveying belt 51. Further, the silica gel moves along with the conveying belt 51 and is finally transferred to the collection box 61 by the second scraping, so that the collection box 61 can not only collect the overflowed silica gel, but also collect the silica gel in the two collection boxes 44.

[0055] The working principle of the present application is:

[0056] When the pressurized silica gel sheet processing equipment 1 works, the silica gel bottom layer is provided by the feeding module, and the coated silica gel bottom layer is wound by the collecting module. The two opposite and rotatable guide rollers 11 limit the silica gel bottom layer during feeding and collecting, so that it is in a horizontal state, facilitating subsequent coating.

[0057] The pump 13 operates to extract the silica gel in the tank 12 and inject it into the feeding pipe 15 connected to the discharge end of the pump 13. The silica gel flows out through the plurality of nozzles 16 arranged in a straight line on the feeding pipe 15 and uniformly flows onto the surface of the silica gel bottom layer, replacing the traditional feeding method to prevent the silica gel from being exposed and contaminated by dust and ensure the purity of the silica gel.

[0058] In the coating unit, the motor drives one rotating rod 24 to rotate, and the chain wheel 25 and chain 26 transmission structure synchronously rotates the two rotating rods 24. The scraping structure of the two scraping assemblies is arranged on the chain 26, and the chain 26 rotates to drive the frame 32, the moving plate 33 and the scraper 34 to move. The scraper 34 uniformly scrapes the silica gel coating on the silica gel bottom layer. The staff can control the distance between the scraper 34 and the silica gel bottom layer by adjusting the position of the lifting part 22, thereby controlling the coating thickness.

[0059] When the moving plate 33 moves, the sliding block passes through the wave-shaped transverse plate 232 on the mounting plate 23. Under the action of the return spring, the moving plate 33 intermittently moves up and down with the scraper 34, so that the surface of the silica gel coating forms a wave-shaped structure.

[0060] The device also has cleaning and excess material collection functions. During cleaning, the guide plate 234 controls the position of the scraper 34 to retract into the mounting groove 35, and the first scraper 42 scrapes the silica gel on both sides of the scraper 34 under the action of the second spring 43, and the silica gel falls into the collection box 44. In terms of excess material collection, the conveying belt 51 of the belt conveyor 5 supports the silica gel bottom layer, and the overflowed silica gel during the scraping process flows onto the conveying belt 51. The second scraper 64 scrapes the silica gel on the surface of the conveying belt 51 under the action of the second tension spring 65, so that it falls into the collection box 61. In addition, the silica gel in the collection box 44 also moves along with the conveying belt 51 and is finally transferred to the collection box 61 by the second scraper 64, realizing resource recycling and equipment maintenance.

[0061] The above description is only the preferred embodiment of the present application, but the protection scope of the present application is not limited to this. Any person skilled in the art can make equivalent replacements or changes according to the technical solution and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered in the protection scope of the present application.
