Description

Technical Field

[0001] The present invention relates to the technical field of scar treatment, and in particular to processing equipment and a process for a pressurized silicone sheet. Background Art

[0002] Burns and abrasions can easily cause hypertrophic scars, which are hard, raised, and pigmented, and sometimes require debridement. Silicone compounds, especially silicone gel, can effectively improve the condition of scar tissue.

[0003] The silicone patch is composed of a silicone base and an elastic fabric belt. The surface of the silicone base is coated with silicone. The elastic fabric belt covers the silicone base to protect the silicone. During processing, a coating device is required to coat a layer of silicone on the surface of the silicone base. After searching, the Chinese patent with 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 base plate, a guide device and a scraper fixing plate driving device are provided on the scraper replacement base plate, and a scraper fixing plate is provided on the guide device. The scraper fixing plate is provided with a scraper fixing recess, the scraper replacement bottom plate is further provided with a scraper magazine, and also includes a scraper pressure plate driving device, and 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-changing device; the material box used by the coating machine is provided with a scraper quick-changing device or the coating machine includes a coating machine material box. The above scheme has the characteristics of simple structure and easy implementation. When applied, it can reduce the difficulty of operation and labor costs, and improve production efficiency and production benefits. However, the above scheme still has the following shortcomings when used in practice: When the above solution is used, the staff places the paint in the material box. When the coating layer passes through the material box, the paint naturally adheres to the surface of the coating layer and is finally scraped flat by a scraper. However, the paint is exposed to the external environment for a long time. Since the paint is exposed to the external environment for a long time, the dust in the environment can easily adhere to the paint, which will cause the purity of the paint to decrease, and then affect the surface quality of the coating layer. Problems such as rough and uneven surface and impurity particles may occur, which will reduce the overall quality and performance of the product, and may also affect the normal progress of subsequent processes and have adverse effects on the final appearance and use effect of the product.

[0004] Therefore, it is necessary to design a processing equipment and process for pressurized silicone sheets to solve the above problems. Summary of the Invention

[0015] A processing technology for a pressurized silicone sheet comprises the following steps: Step 1: Prepare the silicone base material and place it on the discharge module; inject the silicone for coating into the material tank, adjust the position of the lifting part according to the requirements of the pressurized silicone sheet, and set the distance between the scraper and the silicone base to control the coating thickness. At the same time, adjust other related parameters such as pump flow rate according to needs; Step 2: Open the unloading module, so that the silicone base layer is in a horizontal state under the limit of two rotatable guide rollers facing each other, and slowly unload it.

[0019] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0020] Reference Figures 1 to 11As shown, a pressurized silicone sheet processing equipment includes a silicone sheet processing equipment 1, which is provided with two rotatable guide rollers 11, and the two guide rollers 11 are arranged opposite to each other. A discharging module is provided at one end of the silicone sheet processing equipment 1, and a receiving module is provided at the other end. The discharging module is used to provide a silicone bottom layer, and the receiving module is used to rewind the silicone bottom layer after coating. During the process of discharging and receiving the silicone bottom layer, the two guide rollers 11 provide a limit for the silicone bottom layer. Under the limiting action of the two guide rollers 11, the silicone bottom layer located between the two guide rollers 11 is in a horizontal state. This design facilitates the silicone coating treatment of the silicone bottom layer. A material tank 12 is fixed on the silicone sheet processing equipment 1 for storing silicone. A pump 13 is installed on the silicone sheet processing equipment 1. The pump 13 The feeding end is connected to the material tank 12, and a side plate 14 is fixed on the silicone sheet processing equipment 1. A feeding pipe 15 is fixed on the side of the side plate 14. A plurality of nozzles 16 are connected to the feeding pipe 15, and the plurality of nozzles 16 are distributed in a linear array. The discharge end of the pump 13 is connected to the feeding pipe 15. When the pump 13 is running, the silicone in the material tank 12 is extracted and injected into the feeding pipe 15. Finally, the silicone flows out through the plurality of nozzles 16 and flows to the surface of the silicone bottom layer. The feeding method proposed by the present invention replaces the traditional coating feeding method. The silicone is stored in the material tank 12 and will not be exposed. The non-exposed silicone can effectively prevent dust from being contaminated, which can ensure the purity of the silicone and avoid the degradation of the silicone performance, the occurrence of defects or the impact of its bonding effect with the bottom layer due to the mixing of dust, thereby improving product quality and stability. The silicone sheet processing equipment 1 is provided with a coating unit, which includes a bracket assembly and two scraping assemblies. The bracket assembly includes two fixed parts 21, and the two fixed parts 21 are both provided with a lift 22 that can be lifted and lowered. The lift 22 can move up and down relative to the fixed part 21, and the fixed part 21 is provided with a driving module for driving the lift 22 to move. The specific structure and working principle of the driving module are the existing technology, and the implementation method adopts conventional means, which are not shown in the figure and will not be described in detail here. A mounting plate 23 is fixed on the two lifting parts 22, and two rotatable rotating rods 24 are provided between the two mounting plates 23. Both ends of the two rotating rods 24 are fixedly sleeved with sprockets 25, and the two opposite sprockets 25 are connected by chains 26 for transmission. A motor is installed on one of the mounting plates 23, and the motor is used to drive one of the rotating rods 24 to rotate. When the motor is running, it can drive the corresponding rotating rod 24 to rotate. The two sets of sprockets 25 and chains 26 transmission structures cooperate with each other to make the two rotating rods 24 rotate synchronously; The scraping assembly is composed of two scraping structures, and the two scraping structures are arranged on two chains 26. Each scraping structure includes two fixing frames 31, and the two fixing frames 31 are respectively fixed on the two chains 26, and the two fixing frames 31 are arranged opposite each other. A frame 32 is fixed on the two fixing frames 31, and a movable plate 33 is slidably provided on the frame 32. A scraper 34 is arranged on the end of the movable plate 33 away from the frame 32. When the two chains 26 rotate, the frame 32 can be driven to move by the two fixing frames 31, and the movable plate 33 and the scraper 34 move accordingly. During the movement, the scraper 34 can evenly scrape the silicone coating on the silicone bottom layer onto the silicone bottom layer to achieve coating. Furthermore, the staff can control the distance between the scraper 34 and the silicone bottom layer by adjusting the position of the two lifting parts 22, thereby controlling the thickness of the silicone coating. On the basis of the above solution, the scraper 34 can also scrape the silicone coating on the silicone bottom layer into a wavy structure, such as Figure 11 As shown, Figure 11 The figure shows a silicone sheet with a wavy surface coating. Compared with traditional silicone coatings with a smooth surface, 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 and reduce local stress concentration, thereby reducing the risk of the adhesive layer falling off. Specifically, the frame 32 and the movable plate 33 are connected by a sliding structure. The sliding structure includes two sliding openings and two sliders. The two sliding openings are respectively opened at both ends of the frame 32. The two sliders are respectively fixed at both ends of the movable plate 33. The two sliders slide in the two sliding openings respectively. Each slider is connected to the frame 32 by a reset spring. By setting the sliding structure, the movable plate 33 can be moved 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. A control assembly is provided on one of the mounting plates 23. The control assembly includes a plurality of transverse plates 232. Each transverse plate 232 is connected to the mounting plate 23 via a first connecting rod 231. The bottom surface of each transverse plate 232 is a wavy structure. The transverse plates 232 are arranged in a linear array. One of the sliders is arranged opposite to the transverse plates 232. When the movable plate 33 moves, one of the sliders will contact the bottom surface of the transverse plates 232. Figure 3As 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. On the basis of the above scheme, the present invention also has the function of cleaning the excess silicone on the scraper 34. This design can prevent the residual silicone coating from accumulating and solidifying on the scraper 34, reduce the trouble and difficulty of subsequent cleaning, save manpower and time costs, and ensure that the surface of the scraper 34 is clean every time it is used, so that the operation of scraping the silicone coating on the bottom layer is more accurate and uniform, thereby improving the construction quality and avoiding the problem of uneven coating thickness caused by the influence of residual coating. Specifically, the top surface of the movable plate 33 is provided with a mounting groove 35 (such as Figure 8 As shown in FIG, the scraper 34 slides in the mounting groove 35, and an arc-shaped first elastic piece 36 is provided at the bottom of the mounting groove 35, and the first elastic piece 36 presses against the scraper 34. Under the elastic force of the first elastic piece 36, the scraper 34 always has a tendency to detach from the mounting groove 35. Limit openings 37 are provided on both sides of the movable plate 33, and the two limit openings 37 are communicated with the mounting groove 35. Fixed rods 38 are fixed at both ends of the scraper 34, and the two fixed rods 38 slide in the two limit openings 37 respectively. Each fixed rod 38 is connected to the movable plate 33 by a first tension spring 39. The two limit openings 37 and the two fixed rods 38 provide a limit for the scraper 34 to prevent the scraper 34 from detaching from the mounting groove 35, and the provision of the first tension spring 39 is used for automatic resetting of the scraper 34. Each frame 32 is provided with a cleaning assembly, which includes two rotating shafts 41, which are rotatably mounted on both sides of the movable plate 33, and a first scraper 42 is fixed to each rotating shaft 41. A plurality of second spring pieces 43 are fixed on both sides of the movable plate 33, and a plurality of second spring pieces 43 located on the same side press the corresponding first scraper 42. Under the elastic force of the plurality of second spring pieces 43, the two first scrapers 42 always have a tendency to resist the two sides of the scraper 34. A collecting box 44 is fixed on both sides of the movable plate 33, and the two collecting boxes 44 are respectively arranged opposite to the two first scrapers 42. A guide assembly is provided on one of the mounting plates 23, and the guide assembly is used to control the positions of the two scrapers 34. The guide assembly includes a guide plate 234 and a second connecting rod 233. The guide plate 234 is connected to the mounting plate 23 through the second connecting rod 233. Figure 10 As shown, the guide plate 234 has two inclined portions and a straight portion, and the two inclined portions are respectively arranged at both ends of the straight portion; As the two scrapers 34 follow the two chains 26, the fixed rod 38 on one end of the scraper 34 contacts the guide plate 234 and moves under the guidance of the guide plate 234. During this process, the fixed rod 38 first contacts one of the inclined portions and moves along the inclined portion, which causes the scraper 34 to move downward while moving horizontally and retract into the mounting groove 35. Then, the fixed rod 38 moves along the straight portion, which keeps the scraper 34 retracted into the mounting groove 35. Finally, the fixed rod 38 moves to a position facing the other inclined portion. When the scraper 34 is in the position of being positioned upward, the scraper 34 is reset under the action of the second elastic piece 43. Therefore, under the guidance of the guide plate 234, the scraper 34 can move up and down when passing the position opposite the guide plate 234. When the scraper 34 moves downward, the two first scrapers 42 will scrape both sides of the scraper 34 and scrape off the silicone adhered to the blade of the scraper 34, so that the silicone is transferred to the two first scrapers 42, thereby cleaning 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. On the basis of the above scheme, the present invention also has a residual material collection function in the process of scraping the silicone. In order to ensure that the silicone coating can evenly cover the silicone bottom layer, the amount of silicone flowing to the silicone bottom layer through the plurality of nozzles 16 must be sufficient. When the scraper 34 scrapes the silicone coating, the silicone coating can fully cover the silicone bottom layer. In this case, excess silicone will overflow from both sides of the silicone bottom layer. The present invention designs a residual material collection component for collecting the overflowed silicone. Specifically, a belt conveyor 5 is installed on the silicone sheet processing equipment 1. The belt conveyor 5 is located between the two fixed parts 21. A conveyor belt 51 is provided on the belt conveyor 5. During the processing, the silicone bottom layer just falls on the conveyor belt 51. The conveyor belt 51 can provide support for the silicone bottom layer so that the scraper 34 can scrape the silicone coating. 4. Scrape the silicone evenly on the silicone bottom layer. During the scraping process, excess silicone overflowing from both sides of the silicone bottom layer will flow onto the conveyor belt 51 and move with the conveyor belt 51. The residual material collection assembly is arranged below the conveyor belt 51. The residual material collection assembly includes a collection box 61. The opening of the collection box 61 faces upward. A shaft 62 is rotatably mounted on the collection box 61. A sleeve 63 is fixed on the shaft 62. A second scraper 64 is fixed on the sleeve 63. The second scraper 64 is connected to the collection box 61 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 fit the conveyor belt 51, which enables the second scraper 64 to scrape off the silicone attached to the surface of the conveyor belt 51 and make the silicone fall into the collection box 61, thereby realizing active collection of excess silicone. It is worth noting that when the scraper 34 moves to the position with the blade facing upward, the scraper 34 is cleaned by the cleaning component, and the silica gel generated during the cleaning process will fall into the two collection boxes 44. When the scraper 34 rotates to the position with the blade facing downward, the openings of the two collection boxes 44 are also facing downward. At this time, the silica gel in the two collection boxes 44 falls onto the conveyor belt 51. Further, the silica gel will move with the conveyor belt 51 and will eventually be transferred to the collection box 61 by the second scraping. Therefore, the collection box 61 can not only collect the overflowed silica gel, but also collect the silica gel in the two collection boxes 44.

[0021] The working principle of the present invention is: When the pressurized silicone sheet processing equipment 1 is working, the discharging module first provides the silicone base layer, and the receiving module rewinds the coated silicone base layer. Two rotatable guide rollers 11 facing each other limit the silicone base layer during the discharging and receiving processes, keeping it in a horizontal state to facilitate subsequent coating. The pump 13 operates to extract the silica gel from the material tank 12 and injects it into the feed pipe 15 connected to the discharge end of the pump 13. The silica gel flows out through a plurality of nozzles 16 distributed in a linear array on the feed pipe 15 and flows evenly to the surface of the silica gel bottom layer, replacing the traditional feeding method, preventing the silica gel from being exposed and contaminated by dust, and ensuring the purity of the silica gel; In the coating unit, a motor drives a rotating rod 24 to rotate, and the two rotating rods 24 rotate synchronously through the sprocket 25 and chain 26 transmission structure. The scraping structures of the two scraping assemblies are arranged on the chain 26. The rotation of the chain 26 drives the frame 32, the movable plate 33 and the scraper 34 to move. The scraper 34 evenly scrapes the silicone coating on the silicone base layer. The staff can control the distance between the scraper 34 and the silicone base layer by adjusting the position of the lifting part 22, thereby controlling the coating thickness. When the movable plate 33 moves, the slider passes through the wavy horizontal plate 232 on the mounting plate 23. Under the action of the reset spring, the movable plate 33 drives the scraper 34 to move up and down intermittently, so that the surface of the silicone coating forms a wavy structure. The equipment also has the functions of cleaning and collecting residual materials. During cleaning, the guide plate 234 controls the position of the scraper 34, retracting it into the installation slot 35. The first scraper 42 scrapes off the silicone on both sides of the scraper 34 under the action of the second spring 43, and the silicone falls into the collection box 44. In terms of residual material collection, the conveyor belt 51 of the belt conveyor 5 supports the bottom layer of silicone. The silicone overflowing during the scraping process flows to the conveyor belt 51. The second scraper 64 scrapes off the silicone on the surface of the conveyor belt 51 under the action of the second tension spring 65, causing it to fall into the collection box 61. In addition, the silicone in the collection box 44 will also move with the conveyor belt 51, and will eventually be transferred to the collection box 61 by the second scraper 64, realizing resource recycling and equipment maintenance.
