Technical Field

[0001] This utility model relates to the field of film application technology, specifically a skin film filling device. Background Technology

[0002] Skin masks are products used for skin care or protection. They are also classified according to their functions, such as moisturizing skin masks, whitening skin masks, anti-wrinkle skin masks, soothing skin masks, and medical skin masks.

[0003] In the process of producing skin patches, the main function of the filling equipment is to fill the prepared plaster onto a flexible substrate, thereby achieving continuous and rapid filling operations and improving the production efficiency of skin patches.

[0004] However, when using this skin-film filling equipment to fill highly viscous plasters onto flexible substrates, stringing may occur between the plaster already filled onto the flexible substrate and the skin-film filling equipment. This results in an uneven distribution of the plaster on the flexible substrate, and may even leave stringy residue on the surface of the equipment or substrate, ultimately affecting the appearance and quality of the product. Therefore, it does not meet the existing requirements. To address this, we have proposed a skin-film filling equipment. Utility Model Content

[0008] The first bevel gear meshes with a second bevel gear, the shaft of the second bevel gear is connected to a rotating shaft, and a cutting fan blade is fixedly sleeved on the lower side of the outer surface of the rotating shaft.

[0009] Preferably, the upper end face of the cutting fan blade is lower than the lower end face of the filling head, and the cutting fan blade is fixed to the rotating shaft by screws.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] The stepper motor 5 (model DM542), conveyor belt 17 (model SRT-100352) and threaded rod 7 (model M16) mentioned in this utility model can be obtained from the market or through private customization.

[0024] Please see Figures 1 to 4 An embodiment of this utility model provides a skin patch filling device, including a synchronously moving filling frame 1, a lifting platform 2 installed at the middle position of the upper end face of the synchronously moving filling frame 1, a plurality of patch filling devices 3 fixedly installed on the upper end face of the lifting platform 2, a filling head 4 fixedly installed at the middle position of the lower end face of the patch filling device 3, a stepper motor 5 fixedly installed inside the lifting platform 2 behind the filling head 4, the output shaft of the stepper motor 5 is connected to a transmission shaft 6 through a coupling, a threaded rod 7 is connected to the front end face of the transmission shaft 6, an internal threaded sleeve 8 is connected to one side of the outer surface of the threaded rod 7 through a threaded structure, a square shaft 9 is provided below the internal threaded sleeve 8, and the rear end of the square shaft 9 is connected to the transmission shaft 6 in series through a synchronous chain 10;

[0025] The outer side of the front end of the square rotating shaft 9 is provided with a noodle-shaped metal shell 11 fixed to the lower end of the internal threaded sleeve 8. The inside of the noodle-shaped metal shell 11 is provided with a first bevel gear 12. The rear end face of the first bevel gear 12 is connected to the noodle-shaped metal shell 11 by a roller bearing. The middle position of the front end face of the first bevel gear 12 is provided with a square through hole 13, and the first bevel gear 12 is movably sleeved on the outer surface of the square rotating shaft 9 through the square through hole 13.

[0026] The first bevel gear 12 meshes with the second bevel gear 14, and the shaft of the second bevel gear 14 is connected to the rotating shaft 15. The lower side of the outer surface of the rotating shaft 15 is fixedly fitted with a cutting fan blade 16.

[0027] A conveyor belt 17 is provided below multiple filling heads 4. Multiple flexible substrates 18 to be filled are placed on the upper surface of the conveyor belt 17, and the positions of the flexible substrates 18 to be filled correspond to the positions of the filling heads 4. When it is necessary to fill the flexible substrate 18 with skin patch ointment, the lifting platform 2 synchronously drives all the patch filling devices 3 and the filling heads 4 fixed to the lower surface of the patch filling device 3 to move downward, so that they are close to the flexible substrate 18 to be filled. During this process, the patch filling device 3 will draw out the ointment and fill it into the upper surface of the flexible substrate 18 through the filling head 4.

[0028] A guide slider is fixedly provided at the middle position of the upper end face of the internal threaded sleeve 8, and the guide slider is slidably connected to the lifting platform 2; since the guide slider is fixedly provided on the upper end face of the internal threaded sleeve 8 which is sleeved on the outer surface of the threaded rod 7 through the threaded structure and is slidably connected to the lifting platform 2, the internal threaded sleeve 8 itself cannot rotate.

[0029] Before starting the equipment for filling, start the stepper motor 5. The stepper motor 5 can drive the threaded rod 7 connected to it through the transmission shaft 6 to rotate. When the threaded rod 7 rotates, the internal threaded sleeve 8, which is threaded to it but cannot rotate on its own, will move back and forth under the drive of the threaded structure. When the lifting platform 2 moves upward, the internal threaded sleeve 8 moves forward. As the internal threaded sleeve 8 moves, the cutting fan blade 16, which is connected to it through the strip metal shell 11 and the shaft 15, will move forward synchronously.

[0030] The inner wall of the square through hole 13 has a square cross-section. The outer surface of the square rotating shaft 9 is in contact with the inner wall of the square through hole 13, and the square rotating shaft 9 and the square through hole 13 are slidably connected. During the rotation of the transmission shaft 6, the square rotating shaft 9, which is connected to it via the synchronous chain 10, will rotate together. Since the inner wall of the square through hole 13 located at the front end face of the first bevel gear 12 is in contact with the outer surface of the square rotating shaft 9, when the square rotating shaft 9 rotates, the first bevel gear 12 will rotate together. The rotating first bevel gear 12 can drive the second bevel gear 14, which meshes with it, to rotate. When the second bevel gear... When the wheel 14 rotates, the shaft 15 connected to the axis of the second bevel gear 14 and the cutting blade 16 fixedly sleeved on the outer surface of the shaft 15 will rotate together. When the plaster that has been filled onto the flexible substrate 18 to be filled has a stringing phenomenon between it and the filling head 4 used for filling operation, the cutting blade 16, which moves forward and rotates, can cut off the stringing plaster, thereby preventing it from remaining on the equipment or the surface of the flexible substrate 18 to be filled, which would ultimately affect the appearance and quality of the product. The above technical solution can improve the product qualification rate of the equipment when filling high-viscosity plaster.

[0031] When the lifting platform 2 moves downward to perform another filling operation, the stepper motor 5 will drive the transmission shaft 6 connected to it to rotate in the opposite direction, thereby moving the cutting blade 16 in the opposite direction to the filling head 4. The above technical solution can prevent the cutting blade 16 from getting too close to the filling head 4, thus preventing the filling head 4 from performing the filling operation.

[0032] The upper end face of the cutting blade 16 is lower than the lower end face of the filling head 4, and the cutting blade 16 is fixed to the rotating shaft 15 by screws; this structure prevents the rotating cutting blade 16 from contacting the filling head 4.

[0033] The front end of the threaded rod 7 is located inside the housing of the lifting platform 2, and the threaded rod 7 located inside the housing of the lifting platform 2 is connected to the lifting platform 2 by a roller bearing; the roller bearing structure between the two can ensure the stability of the rotating threaded rod 7.

[0034] A protective cover plate is provided below the stepper motor 5 on the lower end face of the lifting platform 2, and the lifting platform 2 and the protective cover plate are fixed together by screws; the protective cover plate can protect the stepper motor 5, and when the stepper motor 5 fails, the protective cover plate can be removed to repair the stepper motor 5.

[0035] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
