Description

Technical Field

[0001] The invention relates to the field of nail piece production equipment, and more specifically to a false nail piece film sticking machine. Background Art

[0002] Manicure is a kind of work to decorate and beautify nails, also known as nail art design, which has the characteristics of diverse forms of expression. Among them, the method of pasting false nail pieces is becoming more and more popular, which is convenient, fast, beautiful and has many styles.

[0003] False nail pieces generally have nail pieces, an adhesive layer compounded on the inner surface of the nail pieces, and a film layer compounded on the outer surface of the nail pieces. In the early stage of production, nail pieces are not injection molded one by one, but multiple pieces are injection molded together on a plate. Moreover, unlike general products, the sizes of nail pieces on the same plate are not consistent, but at least one set matching the size of ten fingers of a human hand is injection molded together, which is called a nail blank plate in the industry. Its structure is as recorded in patent ZL201930334489X. There is a main casting rib in the middle, and on both sides of the main casting rib, there are ten false nail pieces connected one to one by ten branch casting ribs. The ten false nail pieces on each side correspond to the size of ten fingernails on a human hand, and gradually decrease from the middle to the sides. In other words, one nail blank plate can be used to cast two sets of false nails at one time.

[0004] False nail tips have only become popular in recent years. Currently, there are very few equipment developed for their production, so manual labor accounts for a relatively large proportion in the false nail tip production workshop.

DETAILED DESCRIPTION

[0022] In order to make the technical means, creative features and objectives of the present invention easier to understand, the present invention is further described below in conjunction with specific embodiments.

[0023] Example: Figure 1 As shown, a false nail film sticking machine includes a frame 1, on which a turntable 2 arranged in a horizontal stepping rotation is arranged, a stepping motor and a rotating shaft connected to the motor shaft are arranged in the frame 1, and the upper end of the rotating shaft is connected to the turntable 2. Each time the stepping motor rotates once, the turntable 2 rotates ninety degrees, that is, a quarter of a turn. Four supporting molds 13 arranged at equal arc length intervals are arranged on the turntable 2, and a positioning groove 14 for storing a nail plate blank is arranged on the upper surface of each supporting mold 13. The positioning groove 14 has a clamping model that matches the shape, size and quantity of the false nail plates on the nail plate blank. The clamping model is divided into two rows, with ten in each row, the middle one is large and the two sides are small, which just matches the size, quantity and layout of the false nail plates on the nail plate blank.

[0024] Each support mold 13 is provided with a station on the side, which are an open space for loading and unloading station 3 for taking and placing nail blanks, an automatic film sticking station 4 for accurately aligning the film strips with the nail film and sticking them to the corresponding false nails on the nail blanks, and a first pressing station 5 and a second pressing station 6 for double insurance to ensure that the nail film is seamlessly pasted on the false nails. The whole machine is divided into four stations, the loading and unloading station 3, the automatic film sticking station 4, and the first pressing station 5 and the second pressing station 6. The structure is flexible and exquisite, the operation is simple and convenient, the labor intensity is reduced, and the production efficiency is improved. Among them, the double insurance pressing station ensures that the nail film is seamlessly pasted on the false nails, which improves the product quality.

[0025] like Figure 2 As shown, the first press-fitting station 5 and the second press-fitting station 6 have the same structure, and both include the following contents: a vertical plate 15 installed vertically on the frame, a first pressing cylinder 16 is arranged at the upper end of the vertical plate 15, a pressing plate 17 is arranged at the lower end of the cylinder shaft of the first pressing cylinder 16, and the lower part of the pressing plate 17 is directly opposite to a corresponding support mold 13. The pressing projection surface size of the pressing plate 17 is adapted to the boundary contour of the positioning groove 14, and the first pressing cylinder of the second press-fitting station is larger in the pressing stroke than the first pressing cylinder of the first press-fitting station, so that the deformation and extrusion degree of the pressing film are higher, thereby ensuring that the film is seamlessly attached to the false nail piece and ensuring the product quality.

[0026] A buffer pad 18 made of elastic material is disposed on the lower side of the pressing plate 17. The elastic material can be various, and the elastic polymer, in this case rubber, not only acts as a buffer to prevent the false nail from being squeezed and broken by a hard collision, but also allows the false nail to settle into the buffer pad, thereby compensating for the false nail surface coating that is not in a flat shape, and can exert force on any curved surface point, thereby ensuring that the film is seamlessly attached to the false nail, and ensuring product quality.

[0027] like Figure 3As shown, the structure of the automatic film laminating station is as follows: a vertical plate 7 is erected on the frame 1 and horizontally crosses the corresponding support mold 13 below it, and the two ends of the side of the vertical plate 7 are respectively provided with a winding plate 8 for storing the film tape raw material in a roll and a waste roller 12 for recycling the waste material after the film laminating. In order to facilitate the recycling of the waste roller 12, a second feeding roller 11 is arranged beside the waste roller 12; a release paper roller 10 for recycling the release paper on the film tape is arranged below the winding plate 8, and in order to facilitate the recycling of the release paper roller 10, a first feeding roller 9 is arranged beside the release paper roller 10; between the winding plate 8 and the waste roller 12 on both sides above the corresponding support mold 13 A front film-fixing rod 19 and a rear film-fixing rod 20 are respectively provided, and a film stripping plate 26 for separating the release paper from the film tape is provided on the side of the front film-fixing rod 19, and a film-fixing frame 21 pressed on the positioning groove 14 in a staggered and non-covering manner is provided between the front film-fixing rod 19 and the rear film-fixing rod 20, and the film-fixing frame 21 is provided on the second downward pressing cylinder 22 on the vertical plate 7, and a third downward pressing cylinder 23 is provided on the film-fixing frame 21, and a top plate 24 is provided below the third downward pressing cylinder 23, and twenty vertically arranged top rods 25 are provided on the lower side surface of the top plate 24, and the number of the top rods 25 is the same as the clamping model in the positioning groove, and the top rods 25 are divided into two rows, and ten top rods in each row are consistent with the clamping model.

[0028] The first feeding roller 9, the second feeding roller 11, the release paper roller 10 and the waste roller 12 are all powered by a servo motor 30, which guides the force from the rear side of the vertical plate 7 through the conveyor belt.

[0029] Each support mold 13 can be installed on the turntable 2 in a lifting manner through a pair of lifting guide rods 27. A through hole is provided on the turntable 2 between each pair of lifting guide rods 27. A top block 28 that can move up and down is implanted in each through hole. The upper end of the top block 28 is connected to the corresponding support mold 13. At the automatic film laminating station, a lifting cylinder 29 is provided below the support mold 13 at the current station, and the cylinder shaft of the lifting cylinder 29 is in contact with the top block 28 of the support mold 13 at the current station.

[0030] In order to facilitate the inspection and maintenance of the film-laminating belt and the ejector rod 25 and other components, at the automatic film-laminating station, all the ejectors 13 passing through the station are not arranged directly against the front film-fixing rod 19 and the rear film-fixing rod 20, but are spaced a certain distance apart. In order to allow the ejectors 13 to contact the film-laminating belt later, the ejectors 13 need to be lifted. Although the ejectors 13 need to be lifted only at this station, for the entire working environment, each ejector 13 needs to be designed to be able to be raised and lowered because they all pass through this station.

[0031] like Figure 4As shown, a film clamping mechanism is arranged beside the film stripping plate 26, and the film clamping mechanism includes a fourth downward pressing cylinder 31, a movable film clamping plate 32 is arranged below the cylinder shaft of the fourth downward pressing cylinder 31, and a fixed film clamping plate 33 is arranged directly below the movable film clamping plate 32 to clamp the film strip in a clutch-type manner. Under the action of the fourth downward pressing cylinder 31, the movable film clamping plate 32 cooperates with the fixed film clamping plate 33 to clamp the film strip tightly, and the film clamping mechanism is used to guide and press the film strip tightly, to prevent the ejector rod from pulling the film strip and deviating from the position when the film is pressed, and to assist the film fixing frame to play a secondary protection role.

[0032] like Figure 5 As shown, a photoelectric sensor 34 is arranged beside the film clamping mechanism. The photoelectric sensor 34 adopts SIKE laser detection electric eye, which is used to effectively control the start and stop of the servo motor, and cooperates with the repeated segment of the film sticking belt to send forward one segment at a time, and each segment is 20 nail film sheets, and is also divided into two rows, each row has 10 sheets, the middle is large and the two sides are small, which just matches the size, quantity and layout of the false nail pieces on the nail blank plate, so the work arrangement is to put a nail blank plate, and step one segment of the repeated segment of the film sticking, which is a perfect match, and repeat in this way, and the efficiency is doubled.

[0033] like Figure 6 As shown, a pair of first material guide rods 35 and second material guide rods 36, both of which are powered, are arranged beside the material coiling disk 8, wherein a conductive spring sheet 3 is arranged on the second material guide rod 36, and the free end of the conductive spring sheet 37 is pressed against the first material guide rod 35 due to its elastic deformation, and the contact surface between the conductive spring sheet 37 and the first material guide rod 35 is insulated by the film tape passing through. An ingenious film tape detection part is designed here to reliably detect whether there is a film tape passing through, which can ensure the normal operation of the equipment. If the film tape is used up or broken, the conductive spring sheet directly contacts the first material guide rod, connecting the first material guide rod and the second material guide rod, thereby alarming and stopping the machine, preventing the equipment from idling and wasting energy.

[0034] Usage: (1) Loading and unloading station: Take and place the nail blanks. At the beginning of the work, put a nail blank in and make the artificial nail pieces on it correspond to the clamping model one by one.

[0035] (2) Automatic film laminating station: The film tape wound on the reel is fed forward, and the release paper is peeled off at the film stripping plate; the release paper is wound back downward and rewound by the release paper roller, and the film tape with the release paper peeled off continues to move forward. The photoelectric sensor controls the start and stop of the servo motor, and the film tape is fed forward in sections in coordination with the repeated sections on the film tape. Each section is twenty sheets of nail film, and is also divided into two rows, with ten sheets in each row, with the middle one larger and the two sides smaller. It just matches the size, quantity and layout of the fake nail pieces on the nail blank plate, so the work arrangement is to put a nail blank plate and step one section of repeated film.

[0036] When a repeated film segment is sent forward, the movable film clamping plate cooperates with the fixed film clamping plate under the action of the fourth pressing cylinder to clamp the repeated film segment, and the previous repeated film segment is just located between the front fixed film rod and the rear fixed film rod and corresponds to the supporting mold.

[0037] The second pressing cylinder works to press the film fixing frame downward, and at the same time the lifting cylinder works to push the top block upward, thereby lifting the support mold away from the turntable surface and slowly coming into contact with the film tape under the front film fixing rod and the rear film fixing rod. The film fixing frame and the support mold clamp the film tape on the positioning groove. Since the film fixing frame is pressed on the positioning groove in a staggered and non-covering manner, the nail film on the film tape is exposed. It happens that the number of designed push rods and the layout are consistent with the clamping model in the positioning groove, so the push rods also correspond to the nail film one by one; then, the third pressing cylinder presses the push rod downward, and the corresponding nail film below is accurately demolded one by one and adhered to the false nail film on the nail blank plate in the positioning groove. Then the second pressing cylinder, the third pressing cylinder and the lifting cylinder are reset, and the corresponding support mold falls back on the turntable surface.

[0038] (3) The first pressing station and the second pressing station: The turntable rotates 90 degrees step by step, and the nail blanks with film laminated are sent to the first pressing station and the second pressing station in turn for complete lamination. Finally, they are taken out by the loading and unloading station, and new unlaminated nail blanks are put in to enter the next cycle. Among them, the film-laminated tape that has consumed the nail film has become waste and is rolled up by the waste roller.

[0039] (4) During the operation of the whole machine, if the film tape is used up or broken, the conductive spring will directly contact the first material guide rod, connecting the first material guide rod and the second material guide rod, thereby alarming and stopping the machine.
