[0004] The existing medical composite material special casting machine will quickly cool and reel the cast film after it is formed. In most cases, a cooling roller is used in this process. The cast film contacts a metal roller with a low-temperature medium inside to reduce its own temperature. However, the medium inside the cooling roller is often a fluid. When the humidity in the environment is high, it may cause condensation on the surface and adhere to the outside of the cooling roller.

[0005] Based on the above-mentioned situation, we found that it is difficult for the existing casting machine to avoid the above problems at the same time. Therefore, we proposed a special casting machine for medical composite materials, which uses a pressure roller with adjustable roller spacing and a hollow roller with a scraping structure to work with a cooling roller to air-cool the passing cast film, thereby reducing the possibility of liquid directly contacting the finished cast film and improving the cooling efficiency. Summary of the invention

[0006] The purpose of the present invention is to provide a special casting machine for medical composite materials. The advantage of the present invention is that the casting film passing through is air-cooled by a pressure roller with adjustable roller spacing and a hollow roller with a scraping structure in cooperation with a cooling roller, thereby reducing the possibility of direct contact of the liquid with the finished casting film and improving the cooling efficiency.

[0007] The above technical objectives of the present invention are achieved through the following technical solutions: a special casting machine for medical composite materials, comprising a forming device and a discharge frame, the discharge frame is installed on the right side of the forming device, a cooling roller is installed on the inner side of the discharge frame, a cooling medium is arranged inside the cooling roller and an external cooling circulation system is connected, a pressure roller is arranged on the top of the cooling roller, a pulling frame is bolted to the inner side of the discharge frame, an active roller is rotatably connected to the inner side of the pulling frame, a top roller is arranged on the top of the active roller, and rubber sleeves are arranged on the surfaces of the active roller and the top roller, a control motor is bolted to the right side of the pulling frame, and the output end of the control motor is bolted to the active roller;

[0008] A scraper is provided on the right side of the cooling roller, a connecting frame is bolted to the right side of the scraper, an arc-shaped outer shell is provided on the right side of the connecting frame, an inner roller is installed on the inner side of the arc-shaped outer shell, a hollow roller is rotatably connected to the inner side of the inner roller, the hollow roller is externally connected to a fan, and an air slot is opened on the inner side of the hollow roller;

[0009] A top frame is provided on the inner side of the discharge frame, a layer frame is provided on the bottom of the top frame, a pressure frame is provided on the bottom of the layer frame, the inner side of the pressure frame is rotatably connected to the pressure roller, a vertical rod is bolted to the top of the pressure frame, the outer side of the vertical rod is slidably connected to the layer frame, a connecting spring is bolted to the bottom of the layer frame, and the bottom of the connecting spring is bolted to the pressure frame.

[0010] The above technical scheme is adopted to form the cast film by setting a forming device, and the discharge frame is used to cool, solidify and guide the formed cast film, and input it to the rear end winding device. The cooling roller is directly in contact with the cast film under the pressure of the pressure roller, and the contact area between the cast film and the cooling roller is increased after being pressed by the pressure roller, so as to cool and solidify the cast film. When in use, according to the width and thickness of the cast film and the forming temperature of the forming device, the vertical height of the layer frame is adjusted along the top frame to adjust the vertical height of the pressure frame and the inner pressure roller, and when in contact with the cast film, if the pressure roller is subjected to too much force, the connecting spring will be deformed, and the pressure frame will rise along the vertical rod to avoid excessive pressure on the cast film and cause damage. The active roller cooperates with the top roller when the cast film passes through the inner side of the pulling frame. When the temperature is high, the control motor will drive the active roller to rotate. At this time, the cast film in contact with it will be pulled to the front and rear sides because it is in contact with the rubber surface with greater friction, so as to avoid the cast film from being stacked or deformed and unable to be used normally. When the ambient humidity is high, the temperature of the cooling roller is low and the temperature of the cast film is high. Condensation water is easily generated on the surface of the cooling roller during contact, and the connecting frame and scraper frame arranged on the outside of the arc-shaped shell will scrape off the water on the surface of the cooling roller to avoid contact between water and the cast film, and the inner roller and the hollow roller on the inside of the arc-shaped shell cooperate with the wind groove. When the external fan blows air into the structure, the air flow will be blown out through the position of the hollow roller and the wind groove to achieve the effect of air cooling on the cast film, thereby further improving the cooling effect. As needed, the hollow roller can be rotated along the inner side of the inner roller to adjust the position of the wind groove, thereby achieving the effect of flexibly adjusting the direction of the air flow.

[0011] The present invention is further configured as follows: an inner plate is slidably connected to the inner side of the connecting frame, a pressure spring is bolted to the left side of the inner plate, the left side of the pressure spring is bolted to the connecting frame, and the right side of the inner plate is bolted to the arc-shaped outer shell.

[0012] By adopting the above technical solution, by setting an inner plate in conjunction with a pressure spring, the inner plate can be retracted into the connecting frame when the scraper frame and the cooling roller are in contact. At this time, the pressure spring is deformed and the connecting frame is pushed to always be in close contact with the surface of the cooling roller.

[0013] The present invention is further configured as follows: a limiting protrusion is provided on the right side of the surface of the hollow roller, a rotating sleeve is rotatably connected to the right side of the hollow roller, and the inner side of the rotating sleeve cooperates with the limiting protrusion.

[0014] By adopting the above technical solution, by setting a limiting protrusion and cooperating with the rotating sleeve, it is possible to facilitate the connection between the hollow roller and the output pipe of the external fan. The limiting protrusion limits the connection between the rotating sleeve and the hollow roller to prevent the structure from loosening, and allows the hollow roller to rotate without affecting the normal operation of other structures.

[0015] The present invention is further configured as follows: a cooling pipe is provided on the inner side of the inner roller, and the cooling pipe is provided on the outer side of the air trough.

[0016] By adopting the above technical solution, a cooling pipe is provided, and the cooling liquid inside the pipe cools the surrounding airflow. When the airflow is blown out from the inner side of the air slot, the airflow can be cooled to improve the cooling effect.

[0017] The present invention is further configured as follows: a heat exchange device and a pumping device are bolted to the rear side of the front discharge rack, and both ends of the cooling pipe are fixedly connected to the heat exchange device and the pumping device respectively.

[0018] By adopting the above technical solution, a heat exchange device is provided in combination with a pumping device to extract and cool the coolant inside the cooling pipe to ensure continuous use of the structure.

[0019] The present invention is further configured as follows: an adjusting screw is threadedly connected to the inner side of the top frame, the bottom of the adjusting screw is rotatably connected to the shelf, a guide rail is bolted to the inner side of the discharge rack, a slider is slidably connected to the inner side of the guide rail, and the slider is bolted to the shelf on one side close to the shelf.

[0020] By adopting the above technical solution, by setting an adjusting screw, the vertical height of the shelf can be adjusted along the top frame when rotating, and the set guide rail cooperates with the slider to limit the movement of the shelf to avoid the structure from tilting or rotating and causing it to be unable to be used normally.

[0021] The present invention is further configured as follows: a fixing frame is bolted to the surface of the inner roller, the front side of the fixing frame is bolted to the discharge frame, and a rotating sleeve is bolted to the outer side of the hollow roller.

[0022] By adopting the above technical solution, by setting up a fixing frame, the discharge frame and the inner roller can be easily connected and fixed, and the rotating sleeve can facilitate the angle adjustment of the hollow roller on the inner side of the inner roller.

[0023] The present invention is further configured as follows: an axle frame is bolted to the inner side of the discharge frame, and a guide shaft is rotatably connected to the inner side of the axle frame.

[0024] By adopting the above technical solution, by providing an axis frame in conjunction with the guide shaft, the passing cast film can be easily guided to avoid structural distortion and limit its discharge position.

[0025] The present invention is further configured as follows: a pull rod is slidably connected to the inner side of the pulling frame, a rotating seat is bolted to the bottom of the pull rod, and the inner side of the rotating seat is rotatably connected to the top roller.

[0026] By adopting the above technical solution, by setting a pull rod to cooperate with the rotating seat, the position of the top roller can be easily adjusted so that it can cooperate with the active roller to pull the front and rear sides of the cast film.

[0027] The present invention is further configured as follows: a return spring is bolted to the top of the rotating seat, the top of the return spring is bolted to the pulling frame, a limiting telescopic rod is provided on the inner side of the return spring, the top of the limiting telescopic rod is bolted to the pulling frame, and the bottom of the limiting telescopic rod is bolted to the rotating seat.

[0028] By adopting the above technical solution, by setting a reset spring and a pulling frame, the top of the rotating seat can be pressed by the spring so that the top roller inside it fits against the surface of the active roller, and the limiting telescopic rod is used to guide the displacement of the structure.

[0029] In summary, the present invention has the following beneficial effects:

[0030] The forming action of the cast film is performed by setting a forming device, and the set discharge frame is used to cool, solidify and guide the formed cast film, and input it to the rear end winding device. The set cooling roller directly contacts the cast film under the pressure of the pressure roller, and the contact area between the cast film and the cooling roller is increased after being pressed by the pressure roller, so as to cool and solidify the cast film. When in use, according to the width and thickness of the cast film and the forming temperature of the forming device, the vertical height of the layer frame is adjusted along the top frame to adjust the vertical height of the pressure frame and the inner pressure roller, and when in contact with the cast film, if the pressure roller is subjected to too much force, the connecting spring will be deformed, and at this time the pressure frame will rise along the vertical rod to avoid excessive pressure on the cast film and cause damage. The set active roller cooperates with the top roller to control the cast film when it passes through the inner side of the pulling frame. The motor will drive the active roller to rotate. At this time, the cast film in contact with it will be pulled to the front and rear sides because it is in contact with the rubber surface with greater friction, so as to prevent the cast film from being stacked or deformed and unable to be used normally. When the ambient humidity is high, the temperature of the cooling roller is low and the temperature of the cast film is high. Condensation water is easily generated on the surface of the cooling roller during contact. The connecting frame and scraper frame arranged on the outside of the arc-shaped shell will scrape off the water on the surface of the cooling roller to prevent water from contacting the cast film. The inner roller and hollow roller on the inside of the arc-shaped shell cooperate with the wind slot. When the external fan blows air into the structure, the air flow will be blown out through the position of the hollow roller and the wind slot to cool the cast film, further improving the cooling effect. The hollow roller can be rotated along the inner side of the inner roller to adjust the position of the wind slot as needed, thereby flexibly adjusting the direction of the air flow.

[0045] The forming action of the cast film is performed by setting a forming device 1, and the discharge frame 2 is used to cool, solidify and guide the cast film after forming, and input it to the rear end winding device. When the cast film passes through the inner side of the pulling frame 16, the control motor 20 will drive the active roller 17 to rotate. At this time, the cast film in contact with it will be pulled to the front and rear sides because of the contact with the rubber surface with large friction, so as to avoid the cast film from being stacked or deformed and unable to be used normally. When the ambient humidity is high, the temperature of the cooling roller 3 is low and the temperature of the cast film is high, and the contact is easy to cause the cast film to be deformed. Condensed water is easily generated on the surface of the cooling roller 3, and the connecting frame 6 and the scraper frame 5 arranged on the outside of the arc-shaped outer shell 7 will scrape off the water on the surface of the cooling roller 3 to avoid contact between water and the cast film. The inner roller 8 and the hollow roller 9 on the inside of the arc-shaped outer shell 7 cooperate with the wind groove 10. When the external fan blows air into the structure, the air flow will be blown out through the position of the hollow roller 9 and the wind groove 10 to achieve the effect of air cooling on the cast film, further improving the cooling effect. As needed, the hollow roller 9 can be rotated along the inner side of the inner roller 8 to adjust the position of the wind groove 10, thereby achieving the effect of flexibly adjusting the direction of the air flow.

The inner side of the rotating sleeve 24 cooperates with the limiting protrusion 23. By setting the limiting protrusion 23 and cooperating with the rotating sleeve 24, it is convenient to connect the hollow roller 9 and the output pipe of the external fan. The limiting protrusion 23 limits the connection between the rotating sleeve 24 and the hollow roller 9 to avoid loosening of the structure, and can make the hollow roller 9 rotate without affecting the normal operation of other structures.

By providing the cooling pipe 25, the surrounding airflow is cooled by the coolant inside. When the airflow is blown out from the inner side of the wind slot 10, the airflow can be cooled to enhance the cooling effect.

[0049] like Fig. 9 As shown, a heat exchange device 26 and a pumping device 27 are bolted to the rear side of the front discharge frame 2, and both ends of the cooling pipe 25 are fixedly connected to the heat exchange device 26 and the pumping device 27 respectively. The heat exchange device 26 is provided in conjunction with the pumping device 27 to extract and cool the coolant inside the cooling pipe 25 to ensure continuous use of the structure.

By setting the fixing frame 31, the discharge frame 2 and the inner roller 8 can be easily connected and fixed, and the rotating sleeve 32 can facilitate the angle adjustment of the hollow roller 9 on the inner side of the inner roller 8.

[0051] like Figure 6 As shown, the inner side of the discharge frame 2 is bolted with an axis frame 33, and the inner side of the axis frame 33 is rotatably connected with a guide shaft 34. By arranging the axis frame 33 to cooperate with the guide shaft 34, the passing cast film can be guided to avoid structural distortion and limit its discharge position.

[0052] like Figure 3 As shown, a pull rod 35 is slidably connected to the inner side of the pulling frame 16, a rotating seat 36 is bolted to the bottom of the pull rod 35, and the inner side of the rotating seat 36 is rotatably connected to the top roller 18. By arranging the pull rod 35 to cooperate with the rotating seat 36, the position of the top roller 18 can be easily adjusted so that it can cooperate with the active roller 17 to pull the front and rear sides of the cast film.

[0054] Brief description of the use process: When in use, the cast film is formed by the forming device 1. When the ambient humidity is high, the temperature of the cooling roller 3 is low and the temperature of the cast film is high. Condensed water is easily generated on the surface of the cooling roller 3 when in contact. The connecting frame 6 and the scraper frame 5 arranged on the outside of the arc-shaped shell 7 will scrape off the water on the surface of the cooling roller 3 to avoid contact between water and the cast film. The inner roller 8 and the hollow roller 9 on the inside of the arc-shaped shell 7 cooperate with the wind groove 10. When the external fan blows air into the structure, the airflow blows out through the position of the hollow roller 9 and the wind groove 10 to achieve the effect of air cooling on the cast film, further improving the cooling effect. The hollow roller 9 is rotated along the inner side of the inner roller 8 to adjust the position of the wind groove 10 as needed, and the airflow direction can be adjusted. When the cast film passes the inner side of the pulling frame 16, the control motor 20 drives the active roller 17 to rotate. At this time, the cast film in contact with it will be pulled to the front and rear sides because it is in contact with the rubber surface with greater friction, so as to avoid lamination or deformation of the cast film.
