Description

Technical Field

[0001] This utility model relates to the field of medical film production technology, and in particular to a film production equipment. Background Technology

[0002] Medical infrared laser imaging film uses a blue polyester film base as a support, with a photosensitive emulsion layer coated on the front and an anti-halo layer coated on the back. During the production of medical dry film, its surface needs to be dried. Typically, the medical film is placed inside a drying device, where a heating mechanism draws in external air, heats the air, and then sends the heated air into the drying chamber to dry the medical film. During the drying process, solvent vapor is generated, which needs to be discharged through a vapor exhaust pipe. Direct discharge of solvent vapor can be harmful to the external environment and the health of workers; therefore, the discharged solvent vapor needs to be treated.

[0003] In traditional external contact recycling (such as external condenser tubes), solvent vapor needs to come into contact with the coolant through the pipe wall. However, the solvent vapor from drying medical film often contains trace amounts of photosensitive residue and film coating debris. These residues tend to adhere to the pipe wall. When too much residue adheres to the pipe wall, it can cause blockage, preventing the steam from directly contacting the pipe wall and resulting in a continuous decrease in heat exchange efficiency. This necessitates frequent shutdowns for cleaning. Based on the above problems, this application proposes a film production equipment. Utility Model Content

[0004] To address the shortcomings of existing technologies, this invention provides a film production equipment to solve the aforementioned problems.

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

[0006] A film production device includes a drying chamber with a hinged lid on top. A hand handle is fixedly installed on the top of the lid, and a sealing plate is fixedly installed on the bottom of the lid. A rectangular sealing ring is fixedly installed on the surface of the sealing plate, and the rectangular sealing ring overlaps with the drying chamber. A placement assembly is installed inside the drying chamber, a hot air conveying assembly is installed on the left side of the drying chamber, and a steam treatment assembly is installed on the right side of the drying chamber.

[0007] Preferably, the placement assembly includes a limiting plate fixedly installed on the lower side wall of the drying oven, a support plate overlapping inside the limiting plate, a stainless steel perforated tray fixedly installed on the top of the support plate, and a number of stainless steel perforated trays, with connecting plates connecting the facing surfaces of the stainless steel perforated trays, and a handle fixedly installed on the top of the uppermost connecting plate.

[0008] Preferably, the hot air conveying assembly includes a fixed plate fixedly installed on the left side of the drying chamber, a flow divider fixedly disposed between the opposing surfaces of the fixed plate, an air outlet pipe fixedly disposed on the right side of the flow divider, the air outlet end of the air outlet pipe passing through the drying chamber and extending into the interior of the drying chamber, and a heating fan fixedly disposed on the left side of the flow divider.

[0009] Preferably, there are several air outlet ducts, and the several air outlet ducts are distributed in a linear array. The air outlet ducts have a rectangular structure, and both the diffuser and the air outlet ducts are made of heat-insulating material.

[0010] Preferably, the steam treatment assembly includes a fixed frame fixedly installed on the right side of the drying chamber, a treatment chamber fixedly installed inside the fixed frame, a steam inlet pipe fixedly installed on the left side, the inlet end of the steam inlet pipe penetrating through the drying chamber and extending into the interior of the drying chamber, a steam outlet pipe fixedly installed on the right side of the treatment chamber, a discharge pipe fixedly installed at the bottom of the treatment chamber, a control valve fixedly installed on the surface of the discharge pipe, an installation frame fixedly installed inside the treatment chamber, a stainless steel inner bladder fixedly installed inside the installation frame, a liquid inlet pipe fixedly installed at the bottom of the stainless steel inner bladder, a liquid inlet pipe fixedly installed inside the stainless steel inner bladder, a sealing plate fixedly installed at the top of the drying chamber, and a scraping assembly provided on the surface of the sealing plate.

[0011] Preferably, the scraping assembly includes a motor bracket fixedly mounted on the top of the sealing plate, a servo motor fixedly mounted on the top of the motor bracket, a coupling fixedly mounted on the output end of the servo motor, a rotating shaft fixedly mounted on the output end of the servo motor via the coupling, a rotating frame fixedly mounted on the bottom end of the rotating shaft, a spring fixedly mounted inside the rotating frame, a scraper fixedly mounted on the end of the spring, and the scraper and the rotating frame being slidably connected.

[0012] Preferably, the number of scrapers is three, and the three scrapers are distributed in a circular array.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: This film production equipment uses a steam treatment component to cool and collect the solvent vapor generated during the drying process of medical film, causing the solvent vapor to condense into a liquid solvent film inside the steam treatment component. Then, a scraping component cleans the inside of the steam treatment component, scraping off the liquid solvent film formed by condensation inside the steam treatment component and scraping off the residue attached to the inside of the steam treatment component. This avoids the situation where excessive residue adheres to the pipe wall, which can cause pipe blockage and prevent steam from directly contacting the pipe wall, resulting in a continuous decrease in heat exchange efficiency. This avoids the need for frequent shutdowns for cleaning when excessive residue adheres to the pipe wall. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example: Refer to Figure 1-6A film production device includes a drying chamber 1, a cover 2 hinged to the top of the drying chamber 1, a hand handle 3 fixedly mounted on the top of the cover 2, a sealing plate 4 fixedly mounted on the bottom of the cover 2, a rectangular sealing ring 5 fixedly mounted on the surface of the sealing plate 4, the rectangular sealing ring 5 overlapping with the drying chamber 1, a placement assembly inside the drying chamber 1, a hot air conveying assembly on the left side of the drying chamber 1, and a steam treatment assembly on the right side of the drying chamber 1. The steam treatment assembly includes a fixed frame 15 fixedly mounted on the right side of the drying chamber 1, a treatment box 16 fixedly mounted inside the fixed frame 15, and a steam inlet pipe 17 fixedly mounted on the left side, the inlet end of the steam inlet pipe 17 penetrating through the drying chamber 1 and extending into the interior of the drying chamber 1. A steam outlet pipe 18 is fixedly installed on the right side of the treatment chamber 16. A discharge pipe 19 is fixedly installed at the bottom of the treatment chamber 16, and a control valve is fixedly installed on the surface of the discharge pipe 19. An installation frame 20 is fixedly installed inside the treatment chamber 16, and a stainless steel inner bladder 21 is fixedly installed inside the installation frame 20. An inlet pipe 22 is fixedly installed at the bottom of the stainless steel inner bladder 21, and an inlet pipe 22 is fixedly installed inside the stainless steel inner bladder 21. A sealing plate 24 is fixedly installed at the top of the drying chamber 1, and a scraping component is installed on the surface of the sealing plate 24. The solvent vapor generated during drying enters the interior of the treatment chamber 16 through the steam inlet pipe 17. At the same time, coolant is transported to the interior of the inlet pipe 22 through an external conveying device. When the coolant passes through the inlet end of the outlet pipe 23, it returns through the outlet pipe 23. The solvent vapor flows into the recycling equipment. When it comes into contact with the stainless steel inner bladder 21, the temperature difference between the stainless steel inner bladder 21 and the solvent vapor causes the solvent vapor to liquefy on the surface of the stainless steel inner bladder 21, forming a liquid solvent film on the surface of the stainless steel inner bladder 21. The scraping assembly includes a motor bracket 25 fixedly installed on the top of the sealing plate 24. A servo motor 26 is fixedly installed on the top of the motor bracket 25. A coupling is fixedly installed at the output end of the servo motor 26. A rotating shaft 27 is fixedly installed at the output end of the servo motor 26 through the coupling. A rotating frame 28 is fixedly installed at the bottom end of the rotating shaft 27. A spring 29 is fixedly installed inside the rotating frame 28. A scraper 30 is fixedly installed at the end of the spring 29. There are three scrapers 30. The scrapers 30 are arranged in a circular array. The scraper 30 and the rotating frame 28 are slidably connected. The servo motor 26 drives the coupling to rotate the rotating shaft 27, which in turn drives the rotating frame 28 to rotate. This causes the rotating frame 28 to drive the scraper 30 to make a circular motion, so that the scraper 30 scrapes off the liquid solvent film adhering to the surface of the stainless steel inner bladder 21, and also scrapes off the trace amount of coating residue adhering to the surface of the stainless steel inner bladder 21. The scraped liquid solvent and residue fall to the bottom of the processing tank 16. Moreover, when the scraper 30 contacts the stainless steel inner bladder 21, the spring 29 is compressed by the scraper 30. When the scraper 30 wears out, the spring 29 pushes the scraper 30 to move, so that the scraper 30 is always in contact with the stainless steel inner bladder 21.

[0023] Specifically, the placement component includes a limiting plate 6 fixedly installed on the lower side wall of the drying chamber 1. A support plate 7 is overlapped inside the limiting plate 6. A stainless steel perforated tray 8 is fixedly installed on the top of the support plate 7. There are several stainless steel perforated trays 8. A connecting plate 9 is connected between the facing surfaces of the several stainless steel perforated trays 8. A handle 10 is fixedly installed on the top of the uppermost connecting plate 9. The medical film to be dried is placed inside the stainless steel perforated tray 8, and the stainless steel perforated tray 8 is placed inside the drying chamber 1 through the handle 10, so that the bottom of the support plate 7 contacts the lower side wall of the drying chamber 1 and the inside of the limiting plate 6. The drying chamber 1 is closed by holding the handle 3, so that the drying chamber 1 drives the sealing plate 4 and the rectangular sealing ring 5 into the interior of the drying chamber 1. The gap between the lid 2 and the drying chamber 1 is sealed by the compression deformation of the rectangular sealing ring 5.

[0024] Specifically, the hot air delivery assembly includes a fixed plate 11 fixedly installed on the left side of the drying chamber 1. A diversion hood 12 is fixedly installed between the opposing surfaces of the fixed plate 11. An air outlet pipe 13 is fixedly installed on the right side of the diversion hood 12. There are several air outlet pipes 13, which are arranged in a linear array. The air outlet pipes 13 have a rectangular structure. Both the diversion hood 12 and the air outlet pipes 13 are made of heat-insulating material. The air outlet end of the air outlet pipe 13 passes through the drying chamber 1 and extends into the interior of the drying chamber 1. A heating fan 14 is fixedly installed on the left side of the diversion hood 12. The heating fan 14 is controlled by an external controller to draw in external air and heat the external air. The heated air enters the interior of the diversion hood 12 and is diverted by the diversion hood 12. The diverted hot air enters the interior of the air outlet pipe 13 and then enters the interior of the drying chamber 1, so that the hot air heats and dries the medical film.

[0025] The film production equipment is connected to 220V AC mains power, and the main controller can be a conventional known device such as a computer for control.

[0026] In use: The solvent vapor generated during drying enters the interior of the processing tank 16 through the steam inlet pipe 17. Simultaneously, coolant is transported to the interior of the inlet pipe 22 via an external conveying device, and then enters the interior of the stainless steel inner bladder 21 through the inlet pipe 22. When the liquid level is higher than the inlet end of the outlet pipe 23, the coolant flows back to the recovery equipment through the outlet pipe 23. When the solvent vapor comes into contact with the stainless steel inner bladder 21, due to the temperature difference between the stainless steel inner bladder 21 and the solvent vapor, the solvent vapor liquefies on the surface of the stainless steel inner bladder 21, forming a liquid solvent film on the surface of the stainless steel inner bladder 21. This film is then controlled by an external controller. The servo motor 26 drives the coupling to rotate the rotating shaft 27, which in turn drives the rotating frame 28 to rotate. This causes the rotating frame 28 to drive the scraper 30 to make a circular motion, which scrapes off the liquid solvent film adhering to the surface of the stainless steel inner bladder 21. At the same time, it scrapes off the trace amount of coating residue adhering to the surface of the stainless steel inner bladder 21. The scraped liquid solvent and residue fall to the bottom of the processing tank 16. When too much is collected inside the processing tank 16, the control valve on the surface of the discharge pipe 19 can be opened to discharge the liquid solvent through the discharge pipe 19. The discharge process is carried out without drying the film.
