Technical Field
[0001] This utility model relates to the technical field of anti-counterfeiting information, and in particular to a production equipment for baked embossed anti-counterfeiting film. Background Technology
[0002] Existing methods for adding anti-counterfeiting information to coated films are usually printing or laser anti-counterfeiting. In laser anti-counterfeiting, the laser holographic anti-counterfeiting film is transferred onto the coated film by hot rolling to form a holographic image with a three-dimensional effect.
[0003] Existing technology CN202220236891.0 discloses an anti-counterfeiting label, specifically relating to a holographic positioning printing anti-counterfeiting label. The holographic positioning printing anti-counterfeiting label includes, from top to bottom, a plastic film layer, a laser coating, a positioning molded information layer, a positioning printing layer, an aluminum plating layer, a release layer, an adhesive layer, and a silicone paper layer. The anti-counterfeiting label is peelable, consisting of a peelable portion and a retaining portion. The peelable portion, from top to bottom, consists of the plastic film layer, laser coating, positioning molded information layer, positioning printing layer, and aluminum plating layer; the retaining portion, from top to bottom, consists of the release layer, adhesive layer, and silicone paper layer. This utility model has a simple label structure, contains rich anti-counterfeiting information, combines holography and positioning printing, and eliminates the need for an additional protective layer above the printed information, enabling functions such as logistics traceability.
[0004] When adding anti-counterfeiting information to the coated film using the above-mentioned existing technology, each addition of anti-counterfeiting information requires positioning to avoid deviation after addition, which would affect the subsequent bonding of the coated film with other products or the printing of other information on the coated film. Repeated positioning would affect the accuracy of the transfer information positioning. Utility Model Content
[0005] The purpose of this invention is to provide a baking-print anti-counterfeiting film production equipment to solve the problem of star information positioning accuracy caused by the need for repositioning after each transfer of anti-counterfeiting information. The transfer is performed by rotating the printing roller, avoiding the decrease in positioning accuracy caused by multiple transfers and positioning.
[0006] To achieve the above objectives, the present invention adopts the following technical solution: a printing anti-counterfeiting film production equipment, comprising a frame, on which are rotatably mounted an unwinding roller for coating film to be transferred with anti-counterfeiting information, a traction component for conveying the coating film, and a winding roller for rewinding the coating film. The frame is also equipped with a printing roller and a heating element for heating the printing roller. The printing roller rotates relative to the frame at the same speed as the coating film conveying speed. The printing roller is a metal roller, and anti-counterfeiting information is provided on its outer peripheral wall. A rubber roller is mounted on the frame, and the rubber roller presses the coating film so that the coating film contacts the outer wall of the printing roller to transfer the anti-counterfeiting information.
[0007] After adopting the above technical solution, this utility model has the following advantages: The anti-counterfeiting coated film to be baked is placed on the unwinding roller, and the coated film is bypassed by the traction component, the printing roller, and the take-up roller. The coated film is placed between the printing roller and the rubber roller, and the rubber roller abuts the coated film against the outer peripheral wall of the printing roller. The heating element is activated to heat up the printing roller. When the coated film is conveyed, the high-temperature printing roller rotates, so that the anti-counterfeiting information on the printing roller is transferred to the coated film, giving the coated film anti-counterfeiting information. Compared with the existing method of transferring anti-counterfeiting information by continuous positioning, it is only necessary to keep the conveying speed of the coated film the same as the rotation speed of the printing roller to achieve the positioning of the anti-counterfeiting information on the coated film, reducing the possibility of decreased positioning accuracy due to uninterrupted positioning during the transfer of anti-counterfeiting information.
[0008] Furthermore, the printing roller is solid, and the anti-counterfeiting information is evenly distributed on the outer peripheral wall of the printing roller.
[0009] By adopting the aforementioned technical solution, the printing roller is made solid, which increases the weight of the printing roller and reduces the deformation of the printing roller during contact with lower surfaces, thus reducing the impact on the transfer effect of anti-counterfeiting information. After the heating element heats the roller, the solid printing roller can maintain a constant temperature, improving the stability of anti-counterfeiting information transfer.
[0010] Furthermore, the frame is equipped with a cooling roller for cooling the coated film after the anti-counterfeiting information has been transferred, and the cooling roller is located between the adhesive roller and the take-up roller.
[0011] By adopting the aforementioned technical solution, the cooling roller is placed between the rubber roller and the winding roller to ensure that the coating film with anti-counterfeiting information is cooled before winding, thereby avoiding the coating film inside the coating film after winding, which has a certain temperature.
[0012] Furthermore, the cooling roller has a cavity for containing coolant.
[0013] By adopting the aforementioned technical solution, the cooling roller is provided with a cavity to accommodate the coolant, thereby improving the cooling effect of the cooling roller.
[0014] Furthermore, the cooling roller has a cavity and a receiving cavity, the opening of the receiving cavity is downward, and an auxiliary roller rotatably connected to the frame is provided inside the receiving cavity. The cooling roller has an air outlet for blowing air toward the coating film.
[0015] Using the aforementioned technical solution, the coated film is cooled by air to prevent the heat from being trapped during winding without being cooled, which would affect the quality of the coated film containing anti-counterfeiting information. The two ends of the auxiliary roller are rotatably connected to the frame, and the outer peripheral wall of the auxiliary roller protrudes from the lower side of the cooling roller and contacts the coated film. During the winding process of the coated film, the auxiliary roller rotates to reduce the friction between the coated film and the cooling roller.
[0016] Furthermore, the traction assembly includes a first traction roller and a second traction roller, which are located on both sides of the printing roller, with the first traction roller located below the printing roller and the second traction roller located above the printing roller.
[0017] Using the aforementioned technical solution, the traction assembly is configured as a first traction roller and a second traction roller. The first traction roller pulls the coating film between the take-up roller and the printing roller to ensure stable unwinding of the coating film. The second traction roller is located between the printing roller and the take-up roller to ensure stable winding of the coating film with anti-counterfeiting information. The first traction roller is positioned below the printing roller, and the second traction roller is positioned on the printing roller to ensure that the coating film contacts the outer peripheral wall of the printing roller between the first traction roller and the second traction roller.
[0018] Furthermore, the rubber roller is located between the first traction roller and the second traction roller, and the axis of the rubber roller is at the same height as the axis of the printing roller.
[0019] By adopting the aforementioned technical solution, the axis of the rubber roller and the axis of the printing roller are set at the same height, so that when the rubber roller presses the coating film against the printing roller, only a small part of the coating film contacts the printing roller. This ensures that when the printing roller transfers and returns information during rotation, the anti-counterfeiting information will not overlap, thus improving the clarity of the anti-counterfeiting information transfer.
[0020] Furthermore, the frame is provided with a guide roller, which is located between the first traction roller and the printing roller, and the projections of the guide roller and the printing roller overlap in the vertical direction.
[0021] By adopting the aforementioned technical solution, a guide roller is set on the frame. The overlap of the projections of the guide roller and the printing roller in the vertical direction ensures that the coating film can contact the outer peripheral wall of the printing roller after passing under the guide roller, thus ensuring that the anti-counterfeiting information can be transferred onto the coating film.
[0022] Furthermore, the frame is provided with an adjustment groove, the rubber roller is slidably disposed in the adjustment groove, and an elastic element is provided in the adjustment groove. The elastic element is in a compressed state and abuts against the rubber roller on the printing roller so that the rubber roller abuts against the outer peripheral wall of the printing roller.
[0023] By adopting the aforementioned technical solution, an adjustment groove is set on the frame, and the rubber roller is slidably placed in the adjustment groove. The rubber roller then abuts against the printing roller through the adjustment groove, ensuring that the rubber roller abuts against the outer peripheral wall of the printing roller. The setting of the elastic element ensures the contact between the rubber roller and the printing roller, thereby ensuring that the clarity of the anti-counterfeiting information transfer is the same.
[0024] Furthermore, the adjusting groove is provided with a sleeve that can extend and retract along the length direction. One end of the sleeve is connected to the frame and the other end is connected to the rubber roller. The sleeve passes through the elastic element.
[0025] By adopting the aforementioned technical solution, a sleeve is set in the adjustment groove, and the elastic element is sleeved on the sleeve to reduce the deformation of the elastic element when the rubber roller is squeezed, which would affect the contact effect between the rubber roller and the printing roller.
[0026] Furthermore, the frame is provided with a pressure roller located above the take-up roller, which presses against the wound coating film to release air.
[0027] Using the aforementioned technical solution, when the coated film with anti-counterfeiting information is wound up, the pressure roller presses against the coated film during the winding process to expel the air between two adjacent turns of the coated film during the winding process, thus preventing air from being wound inside the winding roller and affecting the quality of the coated film.

[0036] The technical solution of this utility model will be described in detail below with specific embodiments. The following specific embodiments can be selected to be combined or substituted with each other according to the actual situation, and the same or similar concepts or processes may not be described again in some embodiments.
[0037] like Figure 1 and Figure 2 As shown, this utility model provides a production equipment for baked-on anti-counterfeiting film, including a frame 1. The frame 1 is equipped with an unwinding roller 2 for the coated film to be baked on, a traction assembly for conveying the coated film, and a winding roller 7 for rewinding the coated film. Specifically, the traction assembly includes a first traction roller 31 and a second traction roller 32. The unwinding roller 2, the first traction roller 31, the second traction roller 32, and the winding roller 7 are all rotatably connected to the frame 1. The frame 1 is equipped with a printing roller 4 and a heating element 41. The printing roller 4 is a metal roller and conducts heat through the heating element 41. The printing roller 4 is rotatably connected to the frame 1, and its rotational speed is the same as the film conveying speed. Specifically, the linear speed of the printing roller 4 is the same as the film conveying speed. The film is conveyed at the same speed. The outer peripheral wall of the printing roller 4 is provided with anti-counterfeiting information. The frame 1 is provided with a rubber roller 5, which is located between the printing roller 4 and the take-up roller 7. The rubber roller 5 squeezes the coating film so that the coating film comes into contact with the outer peripheral wall of the printing roller 4. After being heated by the heating element 41, the printing roller 4 transfers the anti-counterfeiting information on the outer peripheral wall to the coating film, so that the coating film has anti-counterfeiting information. Compared with the existing method of transferring anti-counterfeiting information by continuous positioning, the conveying speed of the coating film is the same as the linear speed of the printing roller 4, which can realize the positioning of anti-counterfeiting information on the coating film and reduce the positioning requirements when transferring anti-counterfeiting information, thus avoiding the decrease in positioning accuracy due to continuous positioning requirements.
[0038] In this embodiment, the printing roller 4 is solid. Compared to a hollow roller, a solid roller 4 is less prone to deformation due to squeezing by the rubber roller 5, avoiding incomplete or unclear information transfer during anti-counterfeiting information transfer, thus improving the accuracy of anti-counterfeiting information transfer by the printing roller 4. Furthermore, the solid design allows the printing roller 4 to maintain a constant temperature for a longer period after being heated by the heating element 41, improving the stability of anti-counterfeiting information transfer. Additionally, the anti-counterfeiting information is evenly distributed on the outer peripheral wall of the printing roller 4, ensuring uniform transfer of the anti-counterfeiting information onto the coating film.
[0039] In another embodiment, such as Figure 2 and Figure 4 As shown, the first traction roller 31 is located between the unwinding roller 2 and the printing roller 4. The first traction roller 31 ensures that the coated film can be stably unwound on the unwinding roller 2. The second traction roller 32 is located between the printing roller 4 and the take-up roller 7. The second traction roller 32 ensures that the coated film after the anti-counterfeiting information is transferred can be stably conveyed and then taken up. The cooling roller 6 is located between the second traction roller 32 and the take-up roller 7 to reduce the impact of the heat generated during the traction of the coated film by the second traction roller 32 on the winding effect of the coated film. The arrangement of the first traction roller 31 below the printing roller 4 and the second traction roller 32 above the printing roller 4 ensures that the coated film can be stably tractioned on both sides of the printing roller 4.
[0040] To further avoid excessive contact between the printing roller 4 and the coating film, such as Figure 4 As shown, the frame 1 is provided with a guide roller 11, which is located between the first traction roller 31 and the printing roller 4. This allows the coated film to pass under the first traction roller 31 and then come into contact with the printing roller 4. The projections of the guide roller 11 and the printing roller 4 overlap in the vertical direction, ensuring that after the coated film is conveyed upward from the guide roller 11, only a small part of it comes into contact with the printing roller 4 under the abutment of the rubber roller 5, thereby improving the clarity of the anti-counterfeiting information transfer.
[0041] In another embodiment, to maintain consistency in the contact force between the rubber roller 5 and the printing roller 4, such as Figure 2 and Figure 3 As shown, the frame 1 is provided with an adjustment groove 12, and the end of the rubber roller 5 is provided with an adjustment block 121. The adjustment block 121 is slidably disposed in the adjustment groove 12. An elastic element 122 is provided in the adjustment groove 12. One end of the elastic element 122 is connected to the adjustment block 121 and the other end is connected to the frame 1. The elastic element 122 is in a compressed state and abuts against the rubber roller 5 against the printing roller 4, so that the rubber roller 5 abuts against the outer peripheral wall of the printing roller 4. Under the action of the elastic element 122, the consistency of the abutting force between the rubber roller 5 and the printing roller 4 is ensured, thereby ensuring that the clarity of the anti-counterfeiting information transfer is the same.
[0042] In this embodiment, as Figure 3As shown, in order to improve the stability of the elastic element 122, a sleeve 123 that can extend and retract along the length of the elastic element 122 is provided in the adjusting groove 12. One end of the sleeve 123 is connected to the frame 1 and the other end is connected to the rubber roller 5. To be precise, the other end of the sleeve 123 is connected to the adjusting block 121. The sleeve 123 extends and retracts with the sliding of the adjusting block 121. The sleeve 123 passes through the elastic element 122 to prevent the elastic element 122 from bending sideways in the compressed state, which would affect the contact effect between the rubber roller 5 and the outer peripheral wall of the printing roller 4.
[0043] To avoid the influence of heat from the wrapping process after the coated film containing anti-counterfeiting information is wound up, such as... Figure 2 and Figure 3 As shown, a cooling roller 6 is provided on the frame 1. The cooling roller 6 is located between the adhesive roller 5 and the take-up roller 7. The cooling roller 6 cools the coated film after the anti-counterfeiting information is transferred, so that the temperature of the coated film during take-up is close to room temperature. This reduces the possibility of the heat being trapped when the hot coated film is taken up, and reduces the possibility of deformation of the coated film in the center due to heat. Specifically, as shown... Figure 3 As shown, the cooling roller 6 has a cavity 61 at its center, which contains a coolant. By placing the coolant in the cavity 61, the temperature of the outer peripheral wall of the cooling roller 6 is reduced, thereby accelerating the cooling rate of the coating film. In another embodiment, such as... Figure 4 and Figure 5 As shown, the cooling roller 6 has a cavity 61 at its center, and an air outlet 63 communicating with the cavity 61 is opened on the outer peripheral wall of the cooling roller 6. The outlet of the air outlet 63 faces the coating film. A fan is provided on the frame 1, and the air outlet of the fan is connected to the cavity 61. After the air enters the cavity 61, it is blown out from the air outlet 63 and blown onto the coating film. Through the arrangement of the fan, the cavity 61 and the air outlet 63, the coating film is cooled by air, avoiding the coating film from being rolled up before being cooled, which would cause the heat to be trapped and affect the quality of the coating film with anti-counterfeiting information; in this embodiment, as Figure 5 As shown, in order to reduce the friction between the coating film and the cooling roller 6, the cooling roller 6 is provided with a receiving cavity 621, and an auxiliary roller 62 is provided in the receiving cavity 621. The two ends of the auxiliary roller 62 are rotatably connected to the frame 1. The outer peripheral wall of the auxiliary roller 62 protrudes from the lower side of the cooling roller 6 and contacts the coating film. During the winding process of the coating film, the auxiliary roller 62 rotates to reduce the friction between the coating film and the cooling roller 6.
[0044] To improve the winding quality of the coating film with anti-counterfeiting information, a pressure roller 8 is provided on the frame 1 above the winding roller 7. The pressure roller 8 presses against the winding coating film to expel air. Specifically, when the coating film with anti-counterfeiting information is wound, air may be trapped between two adjacent layers of coating film, forming air bubbles. If the air bubbles cannot be expelled, the coating film will deform as it gradually wraps around the film. By pressing the coating film during the winding process with the pressure roller 8, the air between two adjacent layers of coating film is expelled, preventing air from being wound inside the winding roller 7 and affecting the quality of the coating film.
[0045] As the coating film is wound up, the outer diameter of the take-up roller 7 gradually increases. To avoid excessive pressure from the pressure roller 8, which could cause the coating film to be wound too tightly, such as... Figure 1 , Figure 2 and Figure 4 As shown, the frame 1 is provided with a mounting groove 13, in which a mounting block 131 is slidably disposed. A spring 132 is provided between the mounting block 131 and the top wall of the mounting groove 13. The spring 132 presses down against the mounting block 131, so that the pressure roller 8 presses against the outer peripheral wall of the take-up roller 7 to vent the coated film. As the diameter of the outer peripheral wall of the take-up roller 7 gradually increases due to the winding of the coated film, the take-up roller 7 presses against the pressure roller 8 upward. The pressure roller 8 drives the mounting block 131 to press against the spring 132 upward, so as to avoid the pressure roller 8 being relatively fixed in position and affecting the winding of the coated film as the diameter of the take-up roller 7 increases. With the setting of the spring 132, the pressure roller 8 can be moved within the deformation range of the spring 132 to achieve the purpose of venting, while the winding is not too tight.
[0046] In another embodiment, such as Figure 1 As shown, the unwinding roller 2, the first traction roller 31, the second traction roller 32, the guide roller 11, the printing roller 4, the rubber roller 5, the winding roller 7, and the pressure roller 8 are all rotatably connected to the frame 1. The drive for their rotation can be a servo motor or other drive components 101 that can drive them to rotate.
[0047] In addition to the preferred embodiments described above, there are other embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection claimed by this utility model.
