Abstract
Description
Technical Field
[0001] This utility model discloses a centrifugal film machine, belonging to the technical field of centrifugal film machine. Background Technology
[0002] A centrifugal film-making machine is a commonly used film-forming machine. It typically includes a drive motor, a rotating drum driven by the motor, a liquid injection mechanism for injecting liquid into the drum, and a heating mechanism for heating. During film formation, the liquid injection mechanism injects film solution into the drum, the drive motor drives the drum to rotate, and the film solution is dispersed onto the inner wall of the drum under centrifugal force. The heating mechanism then heats the film solution, causing it to solidify and form a film. During drum rotation, the film solution inside the drum can easily splash out, potentially adhering to the drive motor or electrical components. This could lead to corrosion of the drive motor due to the film solution, reducing its lifespan. Utility Model Content
[0003] The purpose of this invention is to solve the problem that the membrane liquid easily splashes onto the drive motor and affects the service life of the drive motor. To this end, a centrifugal film machine is provided, in which a partition separates the roller and the drive motor into a first working area and a second working area, respectively, to prevent the membrane liquid from affecting the drive motor.
[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:
[0005] A centrifugal film machine includes a frame, a drive motor and a drum driven by the drive motor to rotate are provided inside the frame, a partition is provided inside the frame to divide the internal space of the frame into a first working area and a second working area, the drive motor is fixed in the first working area and the drive motor is driven by a rotating shaft, the drum is located in the second working area, the rotating shaft passes through the partition and is fixedly connected to the drum and is coaxially arranged, an opening is formed on the side of the drum away from the partition, a liquid collection tank is provided in the second working area, the liquid collection tank is formed at the edge of the opening of the drum, the liquid collection tank is provided with a plurality of fixed columns, the fixed columns are fixedly connected to the partition and the fixed columns are evenly spaced along the circumference of the liquid collection tank.
[0006] The beneficial effects of using this utility model are:
[0007] The partition described in this invention divides the internal space of the frame into a first working area and a second working area. The drive motor is located in the first working area, and the roller is located in the second working area. The partition separates the drive motor and the roller into the two working areas. The partition can prevent the film liquid from splashing into the first working area, thereby preventing the drive motor or electrical components from short-circuiting or corroding due to film liquid adhesion, which helps to extend the service life of the drive motor and electrical components. In addition, the heating mechanism is also located in the second working area. The partition can also prevent the heat generated by the heating mechanism from entering the first working area, which helps to reduce the heating rate of the first working area, avoid the drive motor being in a high-temperature working environment for a long time, prevent the drive motor from experiencing insulation aging or performance degradation due to high temperature, and help extend the service life of the drive motor. Secondly, adding a partition can also absorb some noise, which helps to reduce the noise generated by the film machine operation and improve the user experience. Furthermore, the liquid collection tank can directly receive splashed film liquid, which can effectively reduce the loss of film liquid, avoid the waste of film liquid, and significantly reduce the film production cost.
[0008] Preferably, the rotating shaft is horizontally positioned.
[0009] Preferably, the collection tanks are arranged in a ring shape, and the collection tanks and the roller are arranged concentrically. Using the aforementioned technical solution, the collection tanks can form a ring around the opening of the roller, ensuring that the membrane liquid ejected by centrifugal force can be effectively collected, thereby limiting and increasing the collection effect of the collection tanks on the membrane liquid.
[0010] Preferably, the inner diameter of the collection tank is larger than the inner diameter of the drum opening. Using the aforementioned technical solution, the inner diameter of the collection tank being larger than the inner diameter of the drum opening allows the collection tank to completely cover the trajectory of the membrane liquid ejected, further improving the collection effect of the collection tank on the membrane liquid. Conversely, when the inner diameter of the collection tank is smaller than the inner diameter of the drum opening, some membrane liquid may impact the outer wall of the collection tank and fall outside the drum or adhere to the outer wall of the collection tank, leading to contamination of the collection tank and waste of the membrane liquid.
[0011] Preferably, the inner wall of the collection tank is radially recessed to form an annular groove. Using the aforementioned technical solution, the annular groove increases the volume of membrane liquid collected in the collection tank, allowing it to collect more membrane liquid and reducing the frequency and number of times the user needs to clean the membrane liquid.
[0012] Preferably, the centrifugal film machine further includes a liquid injection mechanism for injecting liquid into the roller and a heating mechanism for heating, both of which are located in the second working area.
[0013] Preferably, the injection mechanism includes an injector and an injection driver that drives the injector. The injector is parallel to the axial direction of the drum, and the injection driver drives the injector to slide along the axial direction of the drum so that the injector enters or leaves the drum.
[0014] Preferably, the heating mechanism includes a plurality of circumferentially distributed heating tubes and a movable component that drives the heating tubes into or out of the drum. The heating tubes and the drum are arranged in concentric circles, and the movable component drives the heating tubes to slide along the axial direction of the drum.

[0027] like Figures 1 to 5 As shown in the figure, this embodiment illustrates a centrifugal film machine, including a frame, a drive motor 2, a roller 3 driven by the drive motor 2 to rotate, a liquid injection mechanism 4 for injecting liquid into the roller 3, and a heating mechanism 5 for heating. The frame 1 is provided with a partition 13 to divide the internal space of the frame into a first working area 11 and a second working area 12. The drive motor 2 is fixed in the first working area 11 and is connected to a rotating shaft. The roller 3, the liquid injection mechanism 4 and the heating mechanism 5 are all located in the second working area 12. The rotating shaft passes through the partition 13 and is fixedly connected to the roller 3 and is coaxially arranged.
[0028] In this embodiment, the partition 13 divides the internal space of the frame into a first working area 11 and a second working area 12. The drive motor 2 is located in the first working area 11, and the roller 3 is located in the second working area 12. The partition 13 separates the drive motor 2 and the roller 3 into two working areas. The partition 13 can prevent the film liquid from splashing into the first working area 11, thereby preventing the drive motor 2 or electrical components from short-circuiting or corroding due to film liquid adhesion, which helps to extend the service life of the drive motor 2 and electrical components. In addition, the heating mechanism 5 is also located in the second working area 12. The partition 13 can also prevent the heat generated by the heating mechanism 5 from entering the first working area 11, which helps to reduce the heating rate of the first working area 11, avoid the drive motor 2 from being in a high-temperature working environment for a long time, prevent the drive motor 2 from experiencing insulation aging or performance degradation due to high temperature, and help extend the service life of the drive motor 2. Secondly, adding the partition 13 can also absorb some noise, which helps to reduce the noise generated by the film machine operation and improve the user experience.
[0029] like Figure 1 and Figure 2 As shown, in this embodiment, the drive motor 2, roller 3, heating mechanism 5, and liquid injection mechanism 4 are all enclosed by a frame, that is, the drive motor 2, roller 3, heating mechanism 5, and liquid injection mechanism 4 are all located inside the frame. A partition 13 is provided inside the frame, which divides the internal space of the frame into a first working area 11 and a second working area 12. The output shaft of the drive motor 2 is connected to a rotating shaft, which is placed horizontally. Both the rotating shaft and the drive motor 2 are located in the first working area 11. One end of the rotating shaft passes through the partition 13 and extends into the second working area 12. The roller 3 has a mounting hole 32 in the middle, and the rotating shaft is anti-rotationally engaged with the mounting hole 32 to achieve a fixed connection between the rotating shaft and the roller 3. The drive motor 2 drives the roller 3 to rotate through the rotating shaft.
[0030] like Figure 3 and Figure 4 As shown, in this embodiment, the rotating shaft is placed horizontally, the central axis of the roller 3 coincides with the rotating shaft, and an opening is formed on the side of the roller 3 away from the partition 13. A liquid collection tank 33 is provided in the second working area 12. The liquid collection tank 33 is formed on the edge of the opening of the roller 3, and the overall structure of the liquid collection tank 33 is annular. The liquid collection tank 33 and the roller 3 are arranged in concentric circles. The liquid collection tank 33 can directly receive the splashed membrane liquid, which can effectively reduce the loss of membrane liquid and avoid the waste of membrane liquid, and can significantly reduce the membrane production cost. The liquid collection tank 33 can form an annular wrapping around the opening of the roller 3 to ensure that the membrane liquid thrown out by centrifugal force can be effectively collected, thereby limiting and increasing the collection effect of the liquid collection tank 33 on the membrane liquid.
[0031] To improve the collection effect of the collection tank 33, in this embodiment, the inner diameter of the collection tank 33 is larger than the inner diameter of the opening of the roller 3, and the inner sidewall of the collection tank 33 is radially recessed to form an annular groove 331. The inner diameter of the collection tank 33 is larger than the inner diameter of the opening of the roller 3, so that the collection tank 33 can completely cover the trajectory of the membrane liquid being thrown out, further improving the collection effect of the collection tank 33 on the membrane liquid. When the inner diameter of the collection tank 33 is smaller than the inner diameter of the opening of the roller 3, some membrane liquid may hit the outer wall of the collection tank 33 and fall outside the roller 3 or adhere to the outer wall of the collection tank 33, which will lead to the collection tank 33 being contaminated and the membrane liquid being wasted. In addition, the annular groove 331 can increase the volume of membrane liquid collected by the collection tank 33, so that the collection tank 33 can collect more membrane liquid, which can reduce the number and frequency of cleaning the membrane liquid by the user.
[0032] like Figure 3 As shown, in this embodiment, the liquid collection tank 33 is provided with a plurality of fixing columns 332, which are fixedly connected to the partition plate 13, and the fixing columns 332 are evenly distributed at intervals along the circumference of the liquid collection tank 33. Of course, it can be understood that in other embodiments, the fixing columns 332 may also be fixed to the bottom plate of the frame.
[0033] like Figure 5 As shown, the liquid injection mechanism 4 in this embodiment includes a liquid injector 42 and a liquid injection driver 41 that drives the liquid injector 42. A connecting plate 43 is installed at the output end of the liquid injection driver 41. The liquid injection driver 41 is connected to the liquid injector 42 through the mounting plate. The length direction of the liquid injector 42 is parallel to the central axis of the roller 3. The liquid injection driver 41 drives the liquid injector 42 to slide along the axial direction of the roller 3 so that the liquid injector 42 enters or leaves the roller 3. The liquid injector 42 is provided with an atomizing nozzle. When it is necessary to inject liquid into the roller 3, the liquid injection driver 41 controls the liquid injector 42 to extend into the roller 3, and then sprays the film liquid onto the inner wall of the roller 3 through the atomizing nozzle to realize the injection of the film liquid. After the injection of the film liquid is completed, the liquid injection driver 41 controls the liquid injector 42 to move away from the roller 3.
[0034] like Figure 5As shown, the heating mechanism 5 in this embodiment includes a heater and a movable component that drives the heater to slide along the axial direction of the roller 3. The heater includes a fixed plate 52, a plurality of heating tubes 511 fixed to the fixed plate 52, and a reflector 512. The number of heating tubes 511 is the same as the number of reflectors 512. The heating tubes 511 and the reflectors 512 correspond one-to-one and are distributed along the circumference of the roller 3. The reflector 512 forms an opening on the side facing the inner wall of the roller 3. The heating tubes 511 are located between the reflector 512 and the inner wall of the roller 3. After the heating tubes 511 are activated, they emit light. Part of the light directly irradiates the inner wall of the roller 3, and another part irradiates the reflector. The reflector emits the part of the light onto the inner wall of the roller 3, thereby increasing the amount of light irradiated by the heating tubes 511 onto the inner wall of the roller 3. This can accelerate the heating efficiency of the heater on the inner wall of the roller 3 and significantly improve the film-making efficiency.
[0035] The centrifugal film machine described in this embodiment also includes a frame, on which a door is rotatably connected. The movable component includes a pull rod 53 connected to a fixed plate 52. One end of the pull rod 53 passes through the door and is connected to a connecting seat 541. A handle 54 is installed on the connecting seat 541. During use, the user drives the heater to slide along the axial direction through the handle 54, thereby enabling the heater to enter or leave the roller 3.
[0036] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Those skilled in the art should understand that this utility model includes, but is not limited to, the content described in the accompanying drawings and the specific embodiments above. Any modifications that do not depart from the functional and structural principles of this utility model will be included within the scope of the claims.
