Description

Technical Field

[0001] This utility model relates to the field of printing equipment technology, specifically to a printing varnishing and coating machine. Background Technology

[0002] In the printing industry, varnishing and coating processes play a vital role in improving the quality and appearance of printed materials. Traditional printing equipment typically includes basic processes such as paper feeding, varnishing, drying, and paper collection when performing varnishing and coating operations. The aim is to provide a high-quality varnish coating to the printed materials and ensure their drying and neat collection.

[0003] However, in actual printing production, especially in the paper conveying process, static electricity is easily generated due to friction between the paper and conveyor belts, as well as the influence of the surrounding environment. This static charge can cause numerous problems for subsequent varnishing processes. On the one hand, static electricity attracts dust and impurities from the surrounding environment. When paper carrying these contaminants enters the varnishing unit, it leads to uneven varnishing, affecting the surface quality of the printed product and causing defects such as pitting and graininess, thus reducing the yield rate. On the other hand, static electricity can also cause paper to adhere to or stick to the conveyor belt, resulting in poor paper transport, paper jams, and other malfunctions, severely impacting production efficiency and increasing production costs and downtime for maintenance.

[0004] Therefore, it is necessary to propose an improved technical solution to address the above problems. Utility Model Content

[0005] To overcome the shortcomings mentioned above, this utility model aims to provide a technical solution that can solve the above problems.

[0006] A printing varnishing and coating machine includes a frame, on which a paper feeding device, a varnishing unit, a drying system, and a paper receiving device are arranged;

[0007] The paper feeding device is located at the beginning of the frame, and its output end is connected to the input end of the varnishing unit for feeding paper to the varnishing unit. The varnishing unit is installed on the frame and located behind the paper feeding device. Its output end corresponds to the input end of the drying system for varnishing the paper from the paper feeding device and transferring the varnished paper to the drying system.

[0008] The drying system is fixed on the frame and located after the varnishing unit. Its output end is connected to the input end of the paper receiving device. It is used to dry the paper after it has been varnished by the varnishing unit and to transfer the dried paper to the paper receiving device. The paper receiving device is located at the end of the frame and connected to the output end of the drying system. It is used to collect the paper after it has been dried by the drying system.

[0009] An antistatic mechanism is installed on the frame and located between the paper feeding device and the varnishing unit. The antistatic mechanism is used to remove static electricity from the paper from the paper feeding device and then transfer the destatically removed paper to the varnishing unit.

[0010] As a further embodiment of this utility model: the frame is provided with a conveying component for conveying paper, and the paper conveying device conveys the paper sequentially to the static elimination mechanism, the varnishing unit, the drying system, and the paper receiving device through the conveying component.

[0011] As a further embodiment of this utility model: the static elimination mechanism includes a box fixedly mounted on a frame and an ion air bar built into the box, wherein the air outlet of the ion air bar is located above the frame conveying component;

[0012] The box body has an input port corresponding to the paper feeding device and an output port corresponding to the varnishing unit on both sides.

[0013] As a further embodiment of this utility model: a linear guide rail is fixedly installed on the inner wall of the box, and at least one sliding component is connected to one side of the linear guide rail. The sliding component includes a slider, a locking member and the ion fan rod. The ion fan rod is fixedly connected to the slider. The ion fan rod can be moved along the length of the linear guide rail by the slider to adjust its position and is fixed by the locking member.

[0014] As a further embodiment of this utility model: a fixed bracket is fixedly connected to the slider, and the ion wind bar is fixedly connected to the slider through the fixed bracket;

[0015] One end of the locking member is fixedly connected to the slider or fixed bracket, and the other end of the locking member contacts one side of the linear guide rail. A positioning groove is provided along the length direction of the guide rail, and the locking member has a corresponding connecting hole for the positioning groove and is engaged with the positioning groove by a screw.

[0016] As a further embodiment of this utility model: the static elimination mechanism also includes a pressure roller assembly fixed on the inner wall of the box, and the pressure roller assembly is located below the air outlet of the ion air bar and close to the conveying component.

[0017] As a further embodiment of this utility model: a side plate is installed inside the box and above the ion air bar, and a power module and a PLC module are provided on the side plate, wherein the ion air bar is electrically connected to the power module and the PLC module.

[0018] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0019] In traditional printing environments, static electricity attracts dust and impurities from the surrounding air. These tiny particles adhere to the paper surface, causing uneven distribution of the varnish coating when the paper enters the varnishing unit. This results in defects such as pitting and graininess on the printed surface. However, the improved printing varnishing and coating machine is equipped with an anti-static mechanism that effectively eliminates static electricity on the paper, preventing it from attracting dust and impurities. This eliminates the interference of these contaminants on the varnishing process at its source. As a result, the coating can be evenly spread on the paper surface during the varnishing process, creating a smooth, flat, and flawless surface effect. This greatly enhances the appearance quality of the printed products, making them more exquisite and high-end, meeting the market's demand for high-quality printed products.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figure 1-3 In this embodiment of the utility model, a printing varnishing and coating machine includes a frame 1, on which a paper feeding device 2, a varnishing unit 3, a drying system 4, and a paper receiving device 5 are provided;

[0029] The paper feeding device 2 is located at the starting end of the frame 1, and its output end is connected to the input end of the varnishing unit 3, for feeding paper to the varnishing unit 3; the varnishing unit 3 is installed on the frame 1 and located behind the paper feeding device 2, and its output end corresponds to the input end of the drying system 4, for varnishing the paper from the paper feeding device 2 and conveying the varnished paper to the drying system 4.

[0030] The drying system 4 is fixed on the frame 1 and located after the varnishing unit 3. Its output end is connected to the input end of the paper receiving device 5. It is used to dry the paper after it has been varnished by the varnishing unit 3 and to transfer the dried paper to the paper receiving device 5. The paper receiving device 5 is located at the end of the frame 1 and is connected to the output end of the drying system 4. It is used to collect the paper after it has been dried by the drying system 4.

[0031] An antistatic mechanism 6 is installed on the frame 1 and located between the paper feeding device 2 and the varnishing unit 3. The antistatic mechanism 6 is used to remove static electricity from the paper from the paper feeding device 2 and to transfer the destatic paper to the varnishing unit 3.

[0032] The frame 1 is equipped with a conveying component for conveying paper. The paper conveying device 2 conveys the paper sequentially to the static elimination mechanism 6, the varnishing unit 3, the drying system 4, and the paper receiving device 5 through the conveying component.

[0033] The static elimination mechanism 6 includes a housing 7 fixedly mounted on the frame 1 and an ion air bar 8 built into the housing 7. The air outlet 9 of the ion air bar 8 is located above the conveying component of the frame 1.

[0034] The box body 7 has an input port 10 corresponding to the paper feeding device 2 and an output port 11 corresponding to the varnishing unit 3 on both sides.

[0035] This printing varnishing and coating machine is an optimized innovation based on the basic varnishing and coating process (paper feeding, varnishing, drying, and paper collection) of traditional printing equipment. It follows the sequential logic of printed material processing. Starting from the paper entering the paper feeding device 2, the paper is guided through each stage in an orderly manner, ensuring the continuity and integrity of the entire varnishing and coating process. In the path of the paper moving from the paper feeding device 2 to the subsequent stages, an anti-static mechanism 6 is specially added between the paper feeding device 2 and the varnishing unit 3, so that the paper is static-free before entering the key varnishing treatment step, laying the foundation for the subsequent high-quality varnishing operation. This design conforms to the process logic of pre-treatment before processing in printing production. All stages work closely together to achieve efficient and high-quality printing varnishing and coating effects.

[0036] The housing 7 of the static eliminator 6 is firmly fixed to the frame 1, creating a relatively independent and enclosed space. The input port 10 and output port 11 designed on both sides of the housing 7 have a clear guiding function. The input port 10 is precisely aligned with the paper output position of the paper feeding device 2, ensuring that the paper can smoothly enter the housing 7 from the paper feeding device 2. The output port 11 corresponds to the paper input position of the varnishing unit 3, so that the paper after static elimination treatment can accurately enter the varnishing unit 3. This housing 7 structure not only provides a stable channel for paper transportation, but also creates a relatively stable space condition free from external interference for the internal static elimination operation, ensuring the effectiveness and reliability of the static elimination process.

[0037] The ion bar 8, a key component for static elimination, is cleverly housed inside the housing 7. Its outlet 9 is precisely located above the conveying component (the component that carries the paper) of the frame 1. The ion bar 8 operates based on the principle of ionization. It generates a high voltage through an internal high-voltage generator, causing the surrounding air to ionize and form a large number of positively and negatively charged ion streams. When the paper passes under the ion bar 8 on the conveying component, these charged ion streams will neutralize the static charge on the paper surface. For example, if the paper surface has accumulated positive static charge due to friction or other reasons, the negatively charged ions generated by the ion bar 8 will be attracted to the paper surface and cancel out the positive charge. Conversely, the same applies. In this way, the ion bar 8 can accurately and efficiently eliminate static electricity on the paper surface, restore the paper to its electrically neutral state, and provide good paper conditions for subsequent varnishing processes.

[0038] The conveying component on the frame 1 is the "link" for paper transport in the entire printing, varnishing and varnishing machine. With the help of this conveying component, the paper feeding device 2 smoothly conveys the paper to the static elimination mechanism 6, the varnishing unit 3, the drying system 4 and the paper receiving device 5 in a predetermined order and rhythm. The conveying component can be a common conveying component such as a conveyor belt or a conveyor roller.

[0039] In summary, in traditional printing environments, static electricity attracts dust and impurities from the surrounding air. These tiny particles adhere to the paper surface, causing uneven distribution of the varnish coating when the paper enters the varnishing unit 3. This results in defects such as pitting and graininess on the printed surface. The improved printing varnishing machine is equipped with an anti-static mechanism 6, which effectively eliminates static electricity on the paper, preventing it from attracting dust and impurities. This eliminates the interference of these contaminants on the varnishing process at its source. As a result, the coating can be evenly spread on the paper surface during the varnishing process, forming a smooth, flat, and flawless surface effect. This greatly enhances the appearance quality of the printed products, making them more exquisite and high-end, meeting the market's demand for high-quality printed products.

[0040] In this embodiment of the present invention, a linear guide rail 12 is fixedly installed on the inner wall of the housing 7. At least one sliding component is connected to one side of the linear guide rail 12. The sliding component includes a slider 13, a locking member 14, and the ion fan rod 8. The ion fan rod 8 is fixedly connected to the slider 13. The ion fan rod 8 can be moved along the length of the linear guide rail 12 by the slider 13 to adjust its position, and is fixed by the locking member 14.

[0041] A linear guide rail 12 is fixedly installed on the inner wall of the housing 7. The linear guide rail 12 provides a precise guide path for the position adjustment of the ion air bar 8. It has a high-precision linear structure to ensure that the ion air bar 8 can maintain stable linear motion during movement. The sliding component located on one side of the linear guide rail 12 is the key part to realize the flexible movement of the ion air bar 8. The slider 13 in the sliding component is fixedly connected to the ion air bar 8. The slider 13 can fit tightly against the linear guide rail 12 and slide freely along the length of the guide rail. This design allows the ion air bar 8 to flexibly change its position relative to the paper within a certain range according to the size of the paper, the static electricity distribution, and the specific requirements of the varnishing process in actual production.

[0042] The locking component 14 is an important part that ensures that the ion air bar 8 can be stably fixed after being adjusted to the appropriate position. When the ion air bar 8 is moved to the required position by the slider 13, the locking component 14 can be used to firmly fix the slider 13 on the linear guide rail 12, preventing the ion air bar 8 from being displaced due to vibration or other external forces during equipment operation. This ensures that the ion air bar 8 can always perform static removal operation on the paper at the optimal position and angle, ensuring the stability and reliability of the static removal effect.

[0043] It should be noted that there are two linear guide rails 12 arranged opposite each other. This design allows the two ends of the ion air bar 8 to be precisely located within the plane defined by the two linear guide rails 12, thereby ensuring that the ion air bar 8 remains stable and horizontal during movement.

[0044] In this embodiment of the utility model, a fixed bracket 15 is fixedly connected to the slider 13, and the ion wind bar 8 is fixedly connected to the slider 13 through the fixed bracket 15.

[0045] One end of the locking member 14 is fixedly connected to the slider 13 or the fixed bracket 15, and the other end of the locking member 14 contacts one side of the linear guide rail 12. A positioning groove 16 is provided along the length direction of the guide rail. The locking member 14 has a connecting hole 17 corresponding to the positioning groove 16 and is engaged with the positioning groove 16 by a screw.

[0046] The fixed bracket 15 fixedly connected to the slider 13 plays a role in stabilizing the ion air bar 8. Since the ion air bar 8 generates airflow and slight vibration during operation, the rigid connection between the fixed bracket 15 and the slider 13 can firmly fix the ion air bar 8 on the slider 13, preventing it from shifting or shaking during operation. This connection method allows the ion air bar 8 and the slider 13 to be precisely positioned along the linear guide rail 12 as a whole, ensuring that the ion air bar 8 maintains a stable working state during the static elimination process, thereby ensuring a uniform and consistent static elimination effect on the paper.

[0047] One end of the locking member 14 is fixedly connected to the slider 13 or the fixed bracket 15, so that it forms a whole with the position adjustment system of the ion air bar 8. The other end of the locking member 14 contacts one side of the linear guide rail 12, and the linear guide rail 12 is provided with a positioning groove 16 along the length direction. The locking member 14 has a corresponding connection hole 17 on the positioning groove 16. When the ion air bar 8 moves to the appropriate position through the slider 13, the screw is passed through the connection hole 17 of the locking member 14 and screwed into the positioning groove 16. Through the tight cooperation between the screw and the positioning groove 16, the locking member 14 fixes the slider 13, thereby firmly locking the ion air bar 8 in the current position.

[0048] In this embodiment of the present invention, the static elimination mechanism 6 further includes a pressure roller assembly 18 fixed on the inner wall of the housing 7, and the pressure roller assembly 18 is located below the air outlet 9 of the ion air bar 8 and close to the conveying component.

[0049] When the paper passes under the ion air bar 8 for static elimination treatment on the conveying component, the pressure roller assembly 18 then acts on the paper. After the ion air bar 8 eliminates the static electricity of the paper, the paper may experience slight undulations or displacement due to factors such as the blowing of the ion air. At this position, the pressure roller assembly 18 can promptly flatten the paper and make it fit tightly against the conveying component, ensuring that the paper maintains a stable posture and position during subsequent conveying, thus preparing it for entering the varnishing unit 3.

[0050] The pressure roller assembly 18 is typically designed with adjustable pressure. For example, the pressure of the pressure roller on the paper can be adjusted by means of springs, screws, or other devices. This is because different thicknesses and materials of paper have different pressure tolerance and required stability. For thinner paper, relatively less pressure is needed to avoid damaging the paper; while for thicker or harder paper, the pressure can be appropriately increased to ensure that it can be tightly pressed against the conveying components, preventing the paper from shifting or jumping during the conveying process. Operators can flexibly adjust the pressure of the pressure roller assembly 18 according to the actual type of paper used to achieve the best paper stability effect.

[0051] In this embodiment of the present invention, a side plate 19 is installed inside the housing 7 and above the ion air bar 8. A power module 20 and a PLC module 21 are provided on the side plate 19. The ion air bar 8 is electrically connected to the power module 20 and the PLC module 21.

[0052] The power supply module 20 is electrically connected to the ion fan bar 8, and its main function is to provide a stable and suitable power supply for the ion fan bar 8. The PLC (Programmable Logic Controller) module is electrically connected to the ion fan bar 8, realizing intelligent control of the ion fan bar 8. The PLC module 21 can accurately control the working state of the ion fan bar 8 according to the preset program and logic, including the start, stop, wind speed adjustment, and ion output intensity adjustment of the ion fan bar 8, thereby facilitating automated production.

[0053] 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 exemplary 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.
