Description

Technical Field

[0001] The present invention belongs to the technical field of TPU film processing, and specifically relates to a medical dressing TPU film processing device. Background Art

[0002] TPU (thermoplastic polyurethane) film is widely used in medical dressings, mainly due to its excellent physical and mechanical properties, biocompatibility and chemical stability. The TPU film is non-toxic, odorless, and will not cause an immune reaction or adverse reaction when contacting human tissues. It has high tensile strength, tear strength and wear resistance, and can meet the usage requirements of medical supplies, ensuring that the dressing is not easily damaged during use, which makes it an ideal choice for medical dressings;

[0003] However, during the production and processing of TPU film, due to insufficient drying of the TPU particle raw materials, after subsequent heating and melting, the raw materials are not uniform and bubbles are generated. The presence of bubbles will affect the product quality of the TPU film. Moreover, when melting the TPU particle raw materials and other additives, a large amount of harmful gases will be generated in the machine case. The direct discharge of these gases will be harmful to human health. However, additionally installing a purification device will greatly increase the production cost, which is not conducive to the development of small processing factories. Summary of the Invention

A corrugated pipe is fixedly connected to the outer wall of the top end of the circular plate, and the top end of the corrugated pipe and the top ends of the two elastic telescopic rods are fixedly connected to the inner wall of the top end of the heating furnace.

[0009] Preferably, an air extraction pipe and an air delivery pipe are fixedly connected through the two ends of the corrugated pipe near the bottom respectively. The other end of the air delivery pipe is fixedly connected through a ring shaft block, and the upper and lower ends of the ring shaft block are movably sleeved on the hollow rod body of the rotating rod. One-way valves are fixedly connected to the pipe bodies of the air extraction pipe and the air delivery pipe.

[0010] Preferably, the transmission and purification structure includes a first meshing assembly and a second meshing assembly. Both the first meshing assembly and the second meshing assembly are composed of two meshing bevel gears. One bevel gear of the first meshing assembly is fixedly connected to the rod body of the rotating rod. A screw rod is fixedly connected to one bevel gear of the second meshing assembly, and a sliding rod is jointly fixedly connected between the other bevel gears of the first meshing assembly and the second meshing assembly.

[0011] Preferably, a sleeve rod is jointly movably sleeved on the rod bodies of the sliding rod and the screw rod. One end rod body of the sleeve rod is specifically fixedly connected to the outer wall of one end of the blanking hopper.

[0016] In the present invention, the gas generated during the TPU particle processing process will naturally rise, and the activated carbon placed in the filter mesh plate will purify it. The rotation of the rotating rod will drive the synchronous rotation of the turntable and the rubber arc plate. Thus, the passively rotating rubber arc plate will repeatedly push against the elastic telescopic member and the corrugated pipe for synchronous telescoping. Thereby, the corrugated pipe can suck the filtered and purified rising gas through negative pressure, and then squeeze the high-temperature gas inside it to be output from the air delivery pipe and input into the rotating rod. Immediately, the high-temperature gas in the rotating rod will naturally disperse into multiple hollow rods. Thus, the rotating multiple hollow rods will stir and dry the TPU particles in the feeding hopper along with the heat, further avoiding the possibility of moisture in the TPU particle raw material, and thus preventing bubbles from appearing in the processed TPU film.

[0017] In the present invention, the rotating rotating rod will synchronously drive the transmission rotation of the meshing component I. The rotation of the meshing component I drives the sliding rod to rotate, and the rotating sliding rod drives the meshing component II to rotate and drive the screw rod to rotate. The rotating screw rod will drive the pressing plate to rotate and move downward, thereby squeezing the atomizing nozzle below to squeeze and spray the absorbent. The sprayed absorbent will fall into the air outlet hopper pipe. The filtered gas will gradually pass through the air outlet hopper pipe and be discharged from the heating furnace during the continuous rising process. The gas passing through the air outlet hopper pipe will also be secondarily filtered by the installed filtering air wheel, and at the same time, it will contact the sprayed absorbent. The absorbent can also perform a tertiary absorption and purification of the gas to ensure that no harmful substances to the human body are discharged from the gas. Description of the Drawings

[0028] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0029] Such as Figures 1 to 7As shown in the figure, the present invention provides a medical dressing TPU film processing device, including a heating furnace 1. A blanking plug 11 is tightly clamped on the bottom plate of the heating furnace 1. A blanking hopper 12 is arranged directly above the heating furnace 1. A drying and purifying part 2 is arranged between the heating furnace 1 and the blanking hopper 12. The drying and purifying part 2 includes a U-shaped plate frame 21 fixedly connected to the outer wall of the heating furnace 1. A motor 22 of the forward and reverse rotation type is fixedly connected to the outer wall of the top of the U-shaped plate frame 21. A rotating rod 23 is fixedly connected to the rotating shaft of the motor 22. The rod body of the rotating rod 23 is rotatably connected through the plates of the U-shaped plate frame 21 and the heating furnace 1. A stirrer 2301 is fixedly connected to the bottom end of the rotating rod 23 for stirring the melted TPU particle raw material. One section of the rod body of the rotating rod 23 is in a hollow state. A drying and blanking structure is arranged on the rod body of the rotating rod 23. A transmission and purification structure is also arranged between the heating furnace 1 and the blanking hopper 12 to ensure that the gas discharged from the heating furnace 1 will not harm human health.

[0030] Adopting the above scheme: By starting the motor 22 on the U-shaped plate frame 21, it drives the rotating rod 23 and the stirrer 2301 to rotate synchronously. The rotating rod 23 will also drive one of the discs 25 and multiple hollow rods 24 to rotate synchronously. When the blanking holes 26 on the two discs 25 are aligned after rotation, the TPU particle raw material in the blanking hopper 12 can be blanked, thereby realizing quantitative blanking. It is blanked into the heating furnace 1 through multiple blanking inclined pipes 28. The gas generated during the processing of TPU particles will naturally rise and be purified by the activated carbon placed in the filter mesh plate 2801. The rotation of the rotating rod 23 will also drive the turntable 29 and the rubber arc plate 230 to rotate synchronously. Thus, the passively rotating rubber arc plate 230 will repeatedly push and squeeze the elastic telescopic member 231 and the corrugated pipe 232 to expand and contract synchronously. Thereby, the corrugated pipe 232 can suck the filtered and purified rising gas through negative pressure, and then output the high-temperature gas inside it from the gas transmission pipe 234 through extrusion and input it into the rotating rod 23. Immediately, the high-temperature gas in the rotating rod 23 will naturally disperse into the multiple hollow rods 24. Thus, the multiple rotating hollow rods 24 will dry and blank the TPU particles in the blanking hopper 12 in a stirring manner, further avoiding the possibility of moisture in the TPU particle raw material and preventing bubbles from appearing in the processed TPU film.

[0031] The drying and feeding structure includes a plurality of hollow rods 24 fixedly connected through the hollow rod body of the rotating rod 23. A disc 25 is fixedly connected and rotatably connected to the rod body of the rotating rod 23 respectively. The two discs 25 are attached to each other, and the two discs 25 are fixedly connected and rotatably attached to the inner wall of the feeding hopper 12 respectively. Feeding holes 26 are formed through the side walls of the two discs 25. A conical block 27 is fixedly connected to the inner wall of the bottom end of the feeding hopper 12, and a plurality of feeding inclined pipes 28 are fixedly connected through the outer wall of the feeding hopper 12 near the bottom in a surrounding manner. The bottom end of each feeding inclined pipe 28 is fixedly connected through to the outer wall of the heating furnace 1. A filter screen plate 2801 filled with activated carbon is fixedly connected to the inner wall of the heating furnace 1 near the top. The outer wall of the bottom end of the filter screen plate 2801 is specifically coated with heat-insulating paint.

[0032] With the above solution: The rotating rod 23 in rotation will also drive one of the discs 25 and a plurality of hollow rods 24 to rotate synchronously. When the feeding holes 26 on the two discs 25 are aligned after rotation, the TPU particle raw materials in the feeding hopper 12 can be fed, thereby realizing quantitative feeding. Slowing down the feeding speed of the TPU particles can also better dry the raw materials that have not been fed. The fed TPU particles will pass through the installation of the conical block 27, so that the raw materials can better pass through the plurality of feeding inclined pipes 28 and be fed into the heating furnace 1, so that the TPU particles are melted at high temperature while being passively stirred in the heating furnace 1. The gas generated during the processing of the TPU particles will naturally rise and be purified by the activated carbon placed in the filter screen plate 2801.

[0033] A turntable 29 is also fixedly connected to the rod body of the rotating rod 23. A rubber arc plate 230 is fixedly connected to the top side wall of the turntable 29. An elastic telescopic member 231 is intermittently attached and slidably connected to the rubber arc plate 230. The elastic telescopic member 231 is specifically composed of two elastic telescopic rods and a circular plate. A corrugated pipe 232 is fixedly connected to the outer wall of the top end of the circular plate. The top end of the corrugated pipe 232 and the top ends of the two elastic telescopic rods are fixedly connected to the inner wall of the top end of the heating furnace 1. An air extraction pipe 233 and an air delivery pipe 234 are fixedly connected through the two ends of the corrugated pipe 232 near the bottom. The other end of the air delivery pipe 234 is fixedly connected through to a ring shaft block 235. The upper and lower ends of the ring shaft block 235 are movably sleeved on the hollow rod body of the rotating rod 23. One-way valves 236 are fixedly connected to the pipe bodies of the air extraction pipe 233 and the air delivery pipe 234.

[0034] Adopting the above solution: The rotation of the rotating rod 23 will also drive the turntable 29 and the rubber arc plate 230 to rotate synchronously. Thus, the passively rotating rubber arc plate 230 will repeatedly squeeze the elastic telescopic member 231, causing it to passively expand and contract while driving the corrugated pipe 232 to expand and contract synchronously. As a result, a negative pressure is generated inside the corrugated pipe 232. Through the negative pressure, the filtered and purified rising gas in the heating furnace 1 can be sucked through the suction pipe 233, and then the high-temperature gas inside it is output from the gas transmission pipe 234 through extrusion and input into the rotating rod 23. The one-way valve 236 installed on the suction pipe 233 and the gas transmission pipe 234 will also enable the gas to flow unidirectionally only for their respective functions in the two pipe bodies;

[0035] Thus, the high-temperature gas in the rotating rod 23 will naturally disperse into multiple hollow rods 24, causing the rotating multiple hollow rods 24 to stir and dry the TPU particles in the hopper 12 along with the heat, thereby avoiding the possibility of moisture in the TPU particle raw materials and preventing bubbles from appearing in the processed TPU film.

[0036] The transmission and purification structure includes a first meshing component 237 and a second meshing component 238. Both the first meshing component 237 and the second meshing component 238 are composed of two meshing bevel gears. One bevel gear of the first meshing component 237 is fixedly connected to the rod body of the rotating rod 23. One bevel gear of the second meshing component 238 is fixedly connected to a screw rod 240. Another bevel gear between the first meshing component 237 and the second meshing component 238 is jointly and fixedly connected with a sliding rod 239. A sleeve rod 241 is jointly and movably sleeved on the rod bodies of the sliding rod 239 and the screw rod 240. One end of the sleeve rod 241 is specifically fixedly connected to the outer wall of one end of the hopper 12. An atomizing nozzle 242 is provided at the bottom end of the screw rod 240, and a pressing plate 243 is also threadedly connected to the rod body of the screw rod 240. The inner wall of the bottom end of the pressing plate 243 is movably sleeved with the top end of the atomizing nozzle 242. The atomizing nozzle 242 is specifically composed of two parts, one part is a telescopic air pipe, and the other part is a nozzle.

[0037] Adopting the above solution: The rotating rotating rod 23 will synchronously drive the first meshing component 237 to rotate. Through the transmission of the first meshing component 237, the sliding rod 239 is driven to rotate, and the rotating sliding rod 239 will drive the second meshing component 238 to rotate and drive the screw rod 240 to rotate. The rotating screw rod 240 will drive the pressing plate 243 to rotate and move downward, thereby squeezing the atomizing nozzle 242 movably sleeved below it. After the absorbent in the absorbent liquid tank 246 is introduced into the atomizing nozzle 242 through the infusion pipe 244, it is squeezed and sprayed, and the sprayed absorbent will fall into the air outlet pipe 247.

[0038] The bottom end of the screw rod 240 is specifically movably sleeved with the inner wall of the telescopic air pipe near the bottom. A liquid infusion pipe 244 is also fixedly connected through the pipe body at one end of the telescopic air pipe near the bottom. A check valve II 245 is fixedly connected to the pipe body of the liquid infusion pipe 244. The other end of the liquid infusion pipe 244 is fixedly connected through to an absorbent liquid tank 246. The outer wall of the other end of the absorbent liquid tank 246 is fixedly connected to the outer wall of one end of the blanking hopper 12. A liquid guide plug is tightly clamped through the top end of the absorbent liquid tank 246. An air outlet pipe 247 is fixedly connected through one end of the heating furnace 1. A filtering air wheel 248 is rotatably connected to the inner wall on one side of the air outlet pipe 247. The filtering air wheel 248 is filled with a desiccant and activated carbon.

[0039] Adopting the above solution: During the continuous upward movement of the filtered gas, it will gradually be discharged from the heating furnace 1 through the air outlet pipe 247. The gas passing through the air outlet pipe 247 will also be secondarily filtered by the installed filtering air wheel 248, and at the same time, it will come into contact with the sprayed absorbent. The absorbent can also perform a third-level absorption and purification on the gas to ensure that no harmful substances to the human body are discharged in the gas.

[0040] It should be added that: After being melted and processed, the TPU raw material can be naturally fed into the extrusion device in the prior art by opening the blanking plug 11 and extruded and cooled into a film shape. The complete processing procedure of the TPU film will not be elaborated here too much.

[0041] Working principle and usage process of the present invention: By starting the motor 22 on the U-shaped plate frame 21, it drives the rotating rod 23 and the stirrer 2301 to rotate synchronously. The rotating rod 23 will also drive one of the discs 25 and multiple hollow rods 24 to rotate synchronously. When the material discharge holes 26 on the two discs 25 are aligned after rotation, the TPU granular raw material in the hopper 12 can be discharged, thereby realizing quantitative discharging. Slowing down the discharging speed of the TPU granules can also better dry the raw material that has not been discharged. The discharged TPU granules will pass through the installation of the conical block 27, so that the raw material can better pass through multiple discharging inclined pipes 28 and be discharged into the heating furnace 1, so that the TPU granules are melted at high temperature while being passively stirred in the heating furnace 1. The gas generated during the processing of the TPU granules will naturally rise and be purified by the activated carbon placed in the filter screen plate 2801. Moreover, the rotation of the rotating rod 23 will also drive the turntable 29 and the rubber arc plate 230 to rotate synchronously. Thus, the passively rotating rubber arc plate 230 will repeatedly squeeze the elastic telescopic member 231, causing it to be passively telescoped while driving the corrugated pipe 232 to be telescoped synchronously. As a result, a negative pressure is generated inside the corrugated pipe 232. Through the negative pressure, the filtered and purified rising gas in the heating furnace 1 can be sucked through the suction pipe 233, and then the high-temperature gas inside it is output from the gas transmission pipe 234 through extrusion and input into the rotating rod 23. Immediately, the high-temperature gas in the rotating rod 23 will naturally disperse into the multiple hollow rods 24. Thus, the rotating multiple hollow rods 24 will stir and dry the TPU granules in the hopper 12 with heat, further avoiding the possibility of moisture in the TPU granular raw material, and thus preventing bubbles from appearing in the processed TPU film;

[0042] At the same time, the rotating rod 23 will synchronously drive the first meshing component 237 to rotate. Through the transmission of the first meshing component 237, the sliding rod 239 is driven to rotate, and the rotating sliding rod 239 will drive the second meshing component 238 to rotate and drive the transmission screw 240 to rotate. The rotating screw 240 will drive the pressing plate 243 to rotate and move downward, thereby squeezing the atomizing nozzle 242 sleeved below it. After the absorbent in the absorbent liquid tank 246 is introduced into the atomizing nozzle 242 through the infusion pipe 244, it is squeezed and sprayed. The sprayed absorbent will fall into the air outlet pipe 247. During the continuous rising process of the filtered gas, it will gradually be discharged from the heating furnace 1 through the air outlet pipe 247. The gas passing through the air outlet pipe 247 will also be secondarily filtered by the installed filter air wheel 248, and at the same time, it will contact the sprayed absorbent. The absorbent can also perform a third-level absorption and purification on the gas to ensure that no harmful substances to the human body are contained in the discharged gas.
