Technical Field
[0001] This utility model relates to the field of silicone gel production technology, and more specifically, to a production apparatus for silicone gel dressings. Background Technology
[0002] Silicone gel dressings are high-performance medical dressings based on organosilicon materials. Due to their unique physicochemical properties, they play an important role in wound care and scar management. However, their production often requires mixing and processing of raw materials. For example, application number "CN202410935484.2" proposes a production equipment for silicone gel dressings. The bottom of the mixing drum is equipped with a bottom stirring device, which includes a stirring disc and a stirring rod. The stirring disc is located at the bottom of the mixing drum, and the root of the stirring rod is fixedly connected to the edge of the stirring disc. Above the stirring disc is a spiral stirring device, which includes a double-layer spiral channel and a rotating roller. The double-layer spiral channel is fixedly installed on the rotating roller, and the top of the rotating roller is connected to a motor and can be driven to rotate by the motor. Inside the rotating roller is a squeezing roller, which is driven to rotate by the motor. The inner wall of the rotating roller is equipped with a heating airbag. When the squeezing roller rotates, it can squeeze the heating airbag and discharge heated air from it.
[0003] However, the above-mentioned technical solutions mainly rely on squeezing the heating airbag to expel hot air and use the hot air to heat the raw material at the top outlet to break the mixed air bubbles. This method relies on local heating. On the one hand, if the heating temperature is not properly controlled or the heating range is too large, it can easily lead to local solidification of the silicone gel raw material, affecting product quality. On the other hand, the range of hot air on air bubbles is limited, and it is difficult to effectively reach the deeper air bubbles inside the raw material. The air bubbles are not completely eliminated and may still require subsequent processing steps. Therefore, we propose a silicone gel dressing production device to solve the above problems. Utility Model Content
[0004] The main purpose of this invention is to provide a production device for silicone gel dressings, which solves the problem that the device mainly relies on extruding hot air by squeezing a heated airbag and using the hot air to heat the raw material at the top outlet to break the mixed air bubbles. This method relies on local heating, which can lead to local solidification of the silicone gel raw material if the heating temperature is not properly controlled or the heating range is too large, thus affecting product quality. In addition, the hot air has a limited range of action on the air bubbles, making it difficult to effectively reach the deeper air bubbles inside the raw material. The air bubbles are not completely eliminated and may still require subsequent processing steps.
[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0006] A silicone gel dressing production apparatus includes a barrel body. A barrel lid is bolted to the upper end of the barrel body. A processing mechanism is installed between the barrel body and the barrel lid. A feed pipe is installed through one end of the upper surface of the barrel lid. A discharge pipe is installed through one side of the lower end of the barrel body. The processing mechanism includes a fixed cylinder installed in the middle of the upper surface of the barrel lid. A transmission rod is movably installed inside the fixed cylinder. A rotating rod is installed through the outer side of the transmission rod inside the fixed cylinder. The outer side of the rotating rod is provided with a first spiral guide groove and a second spiral guide groove. A pressure plate is installed inside the fixed cylinder. A guide block is movably installed at one end of the pressure plate near the rotating rod. The guide block is engaged inside the first spiral guide groove and the second spiral guide groove. A plurality of first connecting pipes are installed through the inside of the pressure plate. A plurality of second connecting pipes are installed through the lower end of the fixed cylinder. An airbag is installed between the overlapping first and second connecting pipes.
[0007] Preferably, valves are installed inside the feed pipe and the discharge pipe, and several air vents are provided through the upper surface of the fixed cylinder. A first one-way valve is installed inside the first connecting pipe, and a second one-way valve is installed inside the second connecting pipe. A motor is installed on the upper surface of the fixed cylinder, and the output end of the motor is connected to the transmission rod.
[0008] Preferably, the fixed cylinder is equipped with several guide rods, the rods of which are movably installed inside the pressure plate. A rotating block is installed at one end of the guide block near the pressure plate, and the rotating block is engaged inside the pressure plate. The first spiral guide groove and the second spiral guide groove have opposite directions of rotation, and the upper and lower sides of the first spiral guide groove and the second spiral guide groove are smoothly connected at their respective close ends.
[0009] Preferably, a rotating shaft is movably installed inside the barrel, and several stirring racks are installed on the outside of the rotating shaft. The stirring racks are movably installed inside the barrel, and the outside of the stirring racks is in contact with the inner wall of the barrel. A locking block is installed at the lower end of the transmission rod, and a locking groove is provided on the upper surface of the rotating shaft. The locking block is locked and installed inside the locking groove.
[0010] Preferably, a sealing frame is installed on the lower inner surface of the barrel, and the sealing frame is engaged with the rotating shaft. The lower inner end of the rotating shaft is provided with a movable groove. A fixed rod is installed in the middle of the upper surface of the sealing frame. The fixed rod is movably installed inside the movable groove. A rotating disk is installed at the upper end of the fixed rod, and the rotating disk is in contact with the upper inner surface of the movable groove.
[0011] Preferably, a movable rod is movably installed between the movable tank and the stirring rack. Several rotating frames are installed on the outer side of the movable rod located inside the tank. A second helical gear is installed at one end of the movable rod located inside the movable tank. A first helical gear is installed at the upper end of the fixed rod. The first helical gear and the second helical gear are meshed together. The lower end of each stirring rack is triangular.
[0012] Compared with the prior art, the present invention has the following beneficial effects:
[0013] (1) In this invention, the alternating cooperation of the first and second spiral guide grooves drives the pressure plate to move up and down to squeeze and stretch the airbag. Combined with the one-way conduction characteristics of the first and second one-way valves, continuous extraction of gas from the barrel is achieved, creating a negative pressure environment inside the barrel. This negative pressure guides the air bubbles inside the raw material to rise naturally and be discharged without relying on heating methods. This fundamentally avoids the problem of local solidification of the silicone gel raw material caused by improper temperature control, ensuring product quality. At the same time, the negative pressure covers the entire inside of the barrel, effectively reaching deep air bubbles in the raw material for more thorough elimination, reducing the need for subsequent processing steps.
[0014] (2) The present invention improves the uniformity of raw material mixing. The rotating shaft drives the stirring rack to revolve, and the meshing transmission of the first helical gear and the second helical gear enables the movable rod to drive the rotating rack to rotate while revolving. Combined with the stirring rack at the lower end of the triangle, the raw materials at the bottom of the barrel and the inner wall edge can be fully stirred, avoiding the situation of raw material sedimentation and insufficient mixing, and further improving the quality of silicone gel dressing.

[0027] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments.

[0029] like Figures 2 to 11As shown, in another embodiment of this utility model, valves are respectively installed inside the feed pipe 4 and the discharge pipe 5. A plurality of air venting grooves 302 are provided through the upper surface of the fixed cylinder 301. A first one-way valve 312 is installed inside the first connecting pipe 311, and a second one-way valve 314 is installed inside the second connecting pipe 313. A motor 304 is installed on the upper surface of the fixed cylinder 301, and the output end of the motor 304 is connected to the transmission rod 303. A plurality of guide rods 328 are installed inside the fixed cylinder 301, and the rods of the guide rods 328 are movably inserted through the upper surface of the fixed cylinder 301. Inside the pressure plate 308, a rotating block 310 is installed on one end of the guide block 309 near the pressure plate 308. The rotating block 310 is engaged inside the pressure plate 308. The first spiral guide groove 306 and the second spiral guide groove 307 rotate in opposite directions. The upper and lower sides of the first spiral guide groove 306 and the second spiral guide groove 307 are smoothly connected at their close ends. A rotating shaft 317 is movably installed inside the barrel 1. Several stirring racks 319 are installed on the outside of the rotating shaft 317. The stirring racks 319 are movably installed inside the barrel 1, and the outside of the stirring racks 319 is... The transmission rod 303 is fitted to the inner wall of the barrel 1. A locking block 316 is installed at the lower end of the rod body. A locking groove 318 is provided on the upper surface of the rotating shaft 317. The locking block 316 is locked inside the locking groove 318. A sealing frame 324 is installed on the lower inner surface of the barrel 1. The sealing frame 324 is locked to the rotating shaft 317. A movable groove 320 is provided at the lower inner end of the rotating shaft 317. A fixing rod 321 is installed in the middle of the upper surface of the sealing frame 324. The fixing rod 321 is movably installed inside the movable groove 320. A rotating... The turntable 322 is in contact with the inner upper surface of the movable groove 320. A movable rod 325 is movably installed between the movable groove 320 and the stirring rack 319. Several rotating racks 326 are installed on the outer side of the rod body inside the barrel 1. A second helical gear 327 is installed on one end of the movable rod 325 inside the movable groove 320. A first helical gear 323 is installed on the upper end of the rod body of the fixed rod 321. The first helical gear 323 and the second helical gear 327 are meshed and connected. The lower end of the stirring rack 319 is triangular.
[0030] The user opens the valve of the feed pipe 4 and adds the silicone gel raw material into the barrel 1 through the feed pipe 4. After adding the raw material, the user closes the valve of the feed pipe 4 to ensure a relatively sealed interior of the barrel 1. Then, the user starts the motor 304 on the upper surface of the fixed cylinder 301, causing the output end of the motor 304 to drive the transmission rod 303 to rotate. The transmission rod 303 then synchronously drives the rotating rod 305 on its outer side to rotate. When the rotating rod 305 rotates, the first spiral guide groove 306 and the second spiral guide groove 307 on the outer side of the rod drive the guide block 309, which is engaged inside, to move. The guide block 309 rotates... The rotating block 310 drives the pressure plate 308 to move up and down along the guide rod 328. When the pressure plate 308 moves down, it squeezes the air bladder 315 between the first connecting pipe 311 and the second connecting pipe 313. As the air pressure inside the air bladder 315 increases, it pushes the first one-way valve 312 inside the first connecting pipe 311 to open. Then, the gas is discharged through the air outlet groove 302 on the fixed cylinder 301 via the first connecting pipe 311. When the pressure plate 308 moves up, it stretches the air bladder 315, creating a negative pressure inside the air bladder 315, which attracts the second one-way valve inside the second connecting pipe 313. When 314 is opened, the gas inside the barrel 1 enters the air bladder 315 through the second connecting pipe 313. Then, as the pressure plate 308 moves up and down repeatedly, it continuously extracts the gas from the barrel 1, creating a stable negative pressure inside the barrel 1. This negative pressure covers the entire interior of the barrel 1, guiding deep air bubbles in the raw material to rise and be discharged. At the same time, the rotating shaft 317 drives the stirring frame 319 to rotate, and the outer side of the stirring frame 319 is in contact with the inner wall of the barrel 1, which can scrape off the residual raw material on the inner wall of the barrel 1 to avoid waste. Furthermore, since the lower end of the stirring frame 319 is triangular, it is convenient to scrape the raw material on the lower surface of the barrel 1, allowing the raw material to move along... The material flows upwards along the inclined plane to prevent sedimentation. At the same time, the first helical gear 323 and the second helical gear 327 mesh, causing the movable rod 325 to drive the rotating frame 326 to rotate while revolving around the center, which enhances the stirring intensity and improves the uniformity of the material mixing. It also pushes the material at the bottom upwards, thereby improving the efficiency of eliminating air bubbles in the material in conjunction with negative pressure. Then, the sealing frame 324 is engaged with the rotating shaft 317, and the fixed rod 321 fits against the movable groove 320 in the rotating shaft 317 through the rotating disk 322 to ensure the sealing during stirring and prevent the material from leaking into the interior of the movable groove 320.
[0031] The motor 304 provides stable power to the entire device, and drives the rotating rod 305 and the rotating shaft 317 to move synchronously through the transmission rod 303, so as to realize the coordinated operation of air extraction and stirring, reduce the number of power sources and simplify the structure.
[0032] The working principle of this silicone gel dressing production device:
[0033] In use, the user first opens the valve of the feed pipe 4 and adds the silicone gel raw material into the barrel 1 through the feed pipe 4. After adding, the user closes the valve of the feed pipe 4 to ensure that the inside of the barrel 1 is relatively sealed. Then, the user starts the motor 304 on the upper surface of the fixed cylinder 301, so that the output end of the motor 304 drives the transmission rod 303 to rotate. Then, the transmission rod 303 synchronously drives the rotating rod 305 on its outer side to rotate. When the rotating rod 305 rotates, the first spiral guide groove 306 and the second spiral guide groove 307 on the outer side of its rod body drive the guide block 309 engaged inside to move. 09 The rotating block 310 drives the pressure plate 308 to move up and down along the guide rod 328. When the pressure plate 308 moves down, it squeezes the air bladder 315 between the first connecting pipe 311 and the second connecting pipe 313. As the air pressure inside the air bladder 315 increases, it pushes the first one-way valve 312 inside the first connecting pipe 311 to open. Then, the gas is discharged through the air outlet groove 302 on the first connecting pipe 311 and the fixed cylinder 301. When the pressure plate 308 moves up, it stretches the air bladder 315, creating a negative pressure inside the air bladder 315, which attracts the second air bladder inside the second connecting pipe 313. When the one-way valve 314 opens, the gas inside the barrel 1 enters the air bladder 315 through the second connecting pipe 313. Then, as the pressure plate 308 moves up and down repeatedly, it continuously extracts the gas from the barrel 1, creating a stable negative pressure inside the barrel 1. This negative pressure covers the entire interior of the barrel 1, guiding deep air bubbles in the raw material to rise and be discharged. Simultaneously, the rotating shaft 317 drives the stirring rack 319 to rotate, and the outer side of the stirring rack 319 is in contact with the inner wall of the barrel 1, which can scrape off residual raw material from the inner wall of the barrel 1, avoiding waste. Furthermore, because the lower end of the stirring rack 319 is triangular, it facilitates scraping the raw material on the lower surface of the barrel 1, allowing the raw material to... The material flows upward along the slope to prevent sedimentation. At the same time, the first helical gear 323 and the second helical gear 327 mesh, causing the movable rod 325 to drive the rotating frame 326 to rotate while revolving around the center, which enhances the stirring intensity and improves the uniformity of the material mixing. It also pushes the material at the lower end upward, thereby improving the efficiency of eliminating air bubbles in the material in conjunction with negative pressure. Then, the sealing frame 324 is engaged with the rotating shaft 317, and the fixed rod 321 fits against the movable groove 320 in the rotating shaft 317 through the rotating disk 322 to ensure the sealing during stirring and prevent the material from leaking into the interior of the movable groove 320.
[0034] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. For those skilled in the art, other variations or modifications can be made based on the above description. It is impossible to exhaustively list all the implementation methods here. Any obvious variations or modifications derived from the technical solutions of this utility model are still within the protection scope of this utility model.
