Description

Technical Field

[0001] This utility model relates to the field of cold sealing film production technology, specifically to a printing device for producing reusable cold sealing film. Background Technology

[0002] Cold-sealing film is a packaging material that can achieve a seal without heating. It is usually composed of multiple layers of materials, including at least one adhesive layer. Under certain pressure, the adhesive layer bonds tightly to the edge of the packaging container to form a seal. Because this sealing method does not require heating, it does not cause heat impact on the product inside the packaging, making it particularly suitable for temperature-sensitive products.

[0003] In the production process of cold sealing film, it is necessary to use printing equipment to print product information, brand logo, patterns, etc. at designated positions for personnel to identify.

[0004] Currently, in traditional printing equipment, the drying of the cold-sealing film after printing is mostly achieved by spraying hot air. However, the direct spraying of hot air makes it difficult for the heat in the airflow to be concentrated and transferred to the cold-sealing film, which easily affects the drying efficiency of the cold-sealing film.

[0005] To address this issue, we propose a printing apparatus for the production of reusable cold-sealed capping film. Utility Model Content

[0006] To overcome the above-mentioned defects, the present invention provides a printing device for producing reusable cold-sealing film, which solves the technical problem in the prior art that the heat in the airflow is difficult to concentrate and transfer to the cold-sealing film, which easily affects the drying efficiency of the cold-sealing film.

[0007] According to one aspect, at least one embodiment of the present invention provides a printing apparatus for producing reusable cold-sealed cap film, including a support base, wherein a take-up roller and an unwind roller are respectively disposed at both ends of the top of the support base, and a flexographic printing assembly is disposed at the end of the top of the support base near the take-up roller, and further comprising:

[0008] A water storage tank is fixedly connected to one end of the top of the support base near the unwinding roller. Both ends of the water storage tank are fixedly connected to support frames, and a hollow cooling roller A is fixedly connected between the two support frames.

[0009] A confluence pipe and a branch pipe are respectively rotatably connected to both ends of the hollow cooling roller A. A hollow cooling roller B is fixedly connected to the end of the confluence pipe and the branch pipe away from the hollow cooling roller A. A transfer pipe is fixedly connected to the middle of both the confluence pipe and the branch pipe.

[0010] A liquid supply assembly is assembled between the merging pipe and the splitting pipe to cooperate with the merging pipe and the splitting pipe in drying the printed cold sealing film.

[0011] An adjustment assembly, which is mounted between the top ends of two support frames, is used to adjust the tension of the cold-sealing film before winding, in conjunction with the transfer tube and the hollow cooling roller B.

[0012] For example, in a printing apparatus for producing a reusable cold-sealing cap film provided in at least one embodiment of this utility model, the liquid supply component includes:

[0013] An external pump is fixedly connected to one side of the water storage tank. An external pipe is fixedly connected to the input end of the external pump. The end of the external pipe away from the external pump is also connected to the water storage tank. A liquid supply pipe is fixedly connected to the output end of the external pump, and the end of the liquid supply pipe away from the external pump is also connected to the transmission pipe at the diversion pipe.

[0014] A temperature-conducting cylinder is fixedly connected to the outside of the liquid supply pipe. A heating element is fixedly connected to one side of the temperature-conducting cylinder, and a return pipe is fixedly connected to the other side of the water storage tank. The end of the return pipe away from the water storage tank is fixedly connected to the transfer pipe at the confluence pipe.

[0015] For example, in a printing apparatus for producing a reusable cold-sealing cap film provided in at least one embodiment of the present invention, the adjusting component includes:

[0016] A central shaft is rotatably connected between the top ends of two support frames. Both ends of the central shaft are fixedly connected to eccentric plates. A transmission slot is opened in the middle of the two eccentric plates, and the two transmission pipes are respectively movably connected inside the two transmission slots.

[0017] A drive motor is fixedly connected to the top of one of the support frames, and the output end of the drive motor is fixedly connected to the central shaft.

[0018] For example, in at least one embodiment of the present invention, a printing apparatus for producing reusable cold-sealed cap film is provided, which further includes: an observation window is provided on the other side of the water tank, and a transparent observation plate is fixedly connected inside the observation window.

[0019] For example, in at least one embodiment of the present invention, a printing device for producing reusable cold-sealed film is provided, which further includes: a liquid level replenishment pipe fixedly connected to the top of one end of the water storage tank, and a drain pipe provided at the bottom of the other end of the water storage tank.

[0020] For example, in at least one embodiment of the present invention, a printing apparatus for producing reusable cold-sealed film is provided, which further includes: a temperature-conducting ring rotatably connected to the outer side of both the hollow cooling roller A and the hollow cooling roller B, and a temperature-conducting pad provided on the outer side of the temperature-conducting ring.

[0021] For example, in at least one embodiment of the present invention, a printing device for producing reusable cold-sealed cap film is provided, which further includes: a stabilizing seat fixedly connected to both sides of the water tank, and the middle part of the liquid supply pipe or return pipe is fixedly connected to the top of the stabilizing seat.

[0022] For example, in at least one embodiment of the present invention, a printing apparatus for producing reusable cold-sealed cap film is provided, which further includes: an extension bracket fixedly connected to the top of one of the support frames, and the drive motor being bolted to one end of the extension bracket.

[0023] The beneficial effects of this utility model are as follows:

[0024] In this invention, through the structural cooperation of hollow cooling roller A, confluence pipe, diversion pipe, hollow cooling roller B and liquid supply assembly, heat can be transferred to the cold sealing film more concentratedly after the cold sealing film is printed by means of the circulating flow of heated liquid, thereby achieving rapid drying of the cold sealing film before it is rolled up.

[0025] In this invention, by utilizing the structural cooperation of the transfer tube and the adjustment component, the tension of the cold-sealing film before winding can be adjusted by changing the position of the hollow cooling roller B, thereby ensuring the winding effect of the cold-sealing film.

[0039] like Figures 1-5 As shown, it illustrates a printing apparatus for producing reusable cold-sealed cap film according to one embodiment of the present invention.

[0040] In some examples, the support base 1 is provided with a take-up roller 2 and an unwind roller 3 at its two ends on the top of the support base 1, and a flexographic printing assembly 4 is provided at the end of the top of the support base 1 near the take-up roller 2. The support base 1 also includes:

[0041] Water storage tank 5 is fixedly connected to the top of the support base 1 near the unwinding roller 3. Both ends of the water storage tank 5 are fixedly connected to support frames 6, and a hollow cooling roller A7 is fixedly connected between the two support frames 6.

[0042] The confluence pipe 8 and the branch pipe 9 are rotatably connected to both ends of the hollow cooling roller A7. The end of the confluence pipe 8 and the branch pipe 9 away from the hollow cooling roller A7 is fixedly connected to the hollow cooling roller B10. The middle part of the confluence pipe 8 and the branch pipe 9 is fixedly connected to the transfer pipe 11.

[0043] Liquid supply assembly 12 is assembled between the confluence tube 8 and the branch tube 9, and is used to cooperate with the confluence tube 8 and the branch tube 9 to form the drying of the cold sealing film after printing.

[0044] Adjustment component 13 is assembled between the top ends of the two support frames 6 and is used to adjust the tension of the cold sealing film before winding in conjunction with the transfer tube 11 and the hollow cooling roller B10.

[0045] More specifically, flexographic printing component 4 includes:

[0046] Anilox roller system: The anilox roller is made of ceramic and is paired with a reverse doctor blade to achieve high-precision ink volume control;

[0047] Ink transfer system: Ink is transferred to the image area of ​​the printing plate via the ink fountain roller and the anilox roller;

[0048] Imprint transfer: Used to apply pressure to a cold-sealing film to transfer ink onto the film;

[0049] In summary, flexographic printing component 4 is a mature existing technology and will not be elaborated further here;

[0050] For example, such as Figure 4 As shown, an observation window is provided on the other side of the water storage tank 5, and a transparent observation plate is fixedly connected inside the observation window.

[0051] More specifically, the observation window provides a clear view of the remaining liquid level in the water tank 5, reminding personnel to replenish it in a timely manner.

[0052] For example, such as Figure 4 As shown, a liquid level replenishment pipe is fixedly connected to the top of one end of the water storage tank 5, and a drain pipe is installed at the bottom of the other end of the water storage tank 5.

[0053] Furthermore, by setting up the liquid level replenishment pipe, when the liquid level inside the water storage tank 5 is insufficient, the medium can be conveniently replenished to meet the need for continuous circulation of the medium. In addition, it can prevent impurities from entering the water storage tank 5 through the liquid level replenishment pipe when not in use. In this embodiment, a sealing plug is provided at the top of the water storage tank 5.

[0054] More specifically, the drain pipe allows the medium inside the water storage tank 5 to be discharged when the medium is not working well. In order to control the opening and closing of the drain pipe, a manual valve is installed on the drain pipe.

[0055] Furthermore, a rotary joint is provided at one end of the confluence pipe 8 and the branch pipe 9 that are assembled with the hollow cooling roller A7, and the hollow cooling roller A7 is connected to the confluence pipe 8 and the hollow cooling roller A7 is connected to the branch pipe 9 through the rotary joint.

[0056] For example, such as Figure 5 As shown, both hollow cooling roller A7 and hollow cooling roller B10 are rotatably connected to a temperature-conducting ring, and a temperature-conducting pad is provided on the outside of the temperature-conducting ring.

[0057] More specifically, by setting up the temperature-conducting ring, the temperature of the medium inside the hollow cooling roller A7 or the hollow cooling roller B10 can be efficiently guided to the cold-sealing film. Furthermore, due to the rotation setting of the temperature-conducting ring, the cold-sealing film can drive the temperature-conducting ring to rotate at the hollow cooling roller A7 or the hollow cooling roller B10 during the winding process, so that the cold-sealing film can be smoothly wound up.

[0058] Furthermore, in order to ensure the smooth connection between the temperature-conducting ring and the hollow cooling roller A7 or the hollow cooling roller B10, in this embodiment, both ends of the outer side of the hollow cooling roller A7 and the hollow cooling roller B10 are provided with assembly grooves, and ball bearings are provided between the inside of the assembly groove and the temperature-conducting ring.

[0059] In this embodiment, in order to concentrate the liquid inside the confluence pipe 8 to the return pipe 19, two one-way valves are provided on the confluence pipe 8, and the two one-way valves are respectively located on both sides of the transfer pipe 11 at the confluence pipe 8.

[0060] In summary, through the overall structural coordination, the cold sealing film can be effectively dried before winding by circulating the heated medium.

[0061] For example, such as Figure 3 As shown, the liquid supply assembly 12 includes:

[0062] An external pump 14 is fixedly connected to one side of the water storage tank 5. An external pipe 15 is fixedly connected to the input end of the external pump 14. The end of the external pipe 15 away from the external pump 14 is also connected to the water storage tank 5. A liquid supply pipe 16 is fixedly connected to the output end of the external pump 14. The end of the liquid supply pipe 16 away from the external pump 14 is also connected to the transmission pipe 11 at the diversion pipe 9.

[0063] The temperature-conducting cylinder 17 is fixedly connected to the outside of the liquid supply pipe 16. A heating element 18 is fixedly connected to one side of the temperature-conducting cylinder 17, and a return pipe 19 is fixedly connected to the other side of the water storage tank 5. The end of the return pipe 19 away from the water storage tank 5 is fixedly connected to the transfer pipe 11 at the confluence pipe 8.

[0064] For example, such as Figure 4 As shown, both sides of the water tank 5 are fixedly connected to a stabilizing base, and the middle part of the liquid supply pipe 16 or the return pipe 19 is also fixedly connected to the top of the stabilizing base.

[0065] More specifically, by setting up the stabilizing seat, the supply pipe 16 or return pipe 19 can be further reinforced to prevent uncontrollable shaking of the supply pipe 16 or return pipe 19 during liquid transfer.

[0066] For example, such as Figure 4As shown, the top ends of the liquid supply pipe 16 and the return pipe 19 are made of flexible material. By utilizing the material properties of the top ends of the liquid supply pipe 16 and the return pipe 19, it is possible to avoid the presence of the liquid supply pipe 16 and the return pipe 19 affecting the rotation of the hollow cooling roller B10.

[0067] For example, such as Figure 4 As shown, the adjustment component 13 includes:

[0068] The central shaft 20 is rotatably connected between the top ends of the two support frames 6. Both ends of the central shaft 20 are fixedly connected to eccentric plates 21. The middle of the two eccentric plates 21 is provided with a transmission groove 22, and the two transmission pipes 11 are respectively movably connected inside the two transmission grooves 22.

[0069] A drive motor 23 is fixedly connected to the top of one of the support frames 6, and the output end of the drive motor 23 is fixedly connected to the central shaft 20.

[0070] For example, such as Figure 4 As shown, an extension bracket is fixedly connected to the top of one of the support frames 6, and the drive motor 23 is bolted to one end of the extension bracket.

[0071] More specifically, by extending the bracket, sufficient space can be provided for the assembly of the drive motor 23 on one of the support frames 6, and with the bolts, the installation efficiency of the drive motor 23 can be ensured, as well as the stability of the drive motor 23 transmission.

[0072] Working principle: First, the reusable cold sealing film is released through the unwinding roller 3, and the free end of the cold sealing film is introduced into the interior of the flexographic printing assembly 4. It passes through the top of the hollow cooling roller A7 and the bottom of the hollow cooling roller B10 in sequence, and then connects to the winding roller 2 to rewind the printed cold sealing film in the subsequent process.

[0073] The flexographic printing assembly 4 is started to print the cold sealing film that has entered the flexographic printing assembly 4. The heating element 18 is also started. The heat generated by the heating element 18 during operation will be transferred to the liquid supply pipe 16 through the heat conduction cylinder 17. At the same time, the external pump 14 is started to draw out the liquid in the water storage tank 5 through the external pipe 15. During the process of the liquid flowing inside the liquid supply pipe 16, it will exchange heat with the heat conduction cylinder 17, causing the liquid to heat up. The heated liquid enters the diversion pipe 9 and is diverted by the diversion pipe 9 and introduced into the hollow cooling roller A7 and the interior of the diversion pipe 9, causing the surfaces of the hollow cooling roller A7 and the hollow cooling roller B10 to heat up. As the cold sealing film passes through the hollow cooling roller A7 or the hollow cooling roller B10, the ink on the cold sealing film can be dried in time. With the flow of liquid in the hollow cooling roller A7 and the hollow cooling roller B10, the liquid will merge at the confluence pipe 8 and return to the interior of the water storage tank 5 through the return pipe 19, thereby realizing the circulation of liquid.

[0074] Furthermore, during the cold sealing film winding process, the drive motor 23 can be started. With the connection between the drive motor 23 and the central shaft 20, the central shaft 20 can drive the eccentric plate 21 to rotate. Since the transmission pipe 11 is movably connected inside the transmission slot 22, when the eccentric plate 21 rotates, it can use the adaptive movement of the transmission pipe 11 inside the transmission slot 22 to drive the hollow cooling roller B10 to adjust its position under the support of the hollow cooling roller A7, the confluence pipe 8, and the diversion pipe 9. This controls the tension force during the cold sealing film winding process and ensures the winding effect of the cold sealing film.

[0075] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
