Description

Technical Field

[0001] The utility model relates to the technical field of printing, in particular to a coating supply device for packaging and decoration printing. Background Art

[0002] In the field of packaging and decoration printing, the quality and supply stability of coatings play a vital role in the quality of printed products. Traditional coating supply devices for packaging and decoration printing often have the following problems:

[0003] On the one hand, the paint may contain various impurities, which will affect the printing quality and cause defects and uneven colors on the printed surface. Some existing supply devices lack effective filtration systems and cannot fully remove impurities in the paint. On the other hand, the paint is prone to precipitation and stratification during storage, making the paint supplied to the printing press uneven and affecting the printing effect. At the same time, the paint may adhere to the inner wall of the storage container, resulting in waste of paint and reduction of effective capacity, and may affect subsequent use after drying.

[0004] Therefore, we propose a coating supply device for packaging decoration printing. Utility Model Content

[0005] The main purpose of the utility model is to provide a coating supply device for packaging and decoration printing, in order to prevent impurities in the coating from affecting the printing quality and causing defects and uneven color on the surface of the printed matter, to prevent the coating from precipitating and stratifying during storage so that the coating supplied to the printing press is uneven and affects the printing effect, and to prevent the coating from adhering to the inner wall of the storage container causing waste of coating, reduction of effective capacity and affecting subsequent use after drying, thereby improving the quality of printed matters, ensuring the stability of coating supply, improving the utilization rate of coating and reducing equipment maintenance costs, which can effectively solve the problems in the background technology.

[0006] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0007] A coating supply device for packaging and decoration printing, comprising a frame, a transmission mechanism is provided at the top of the frame, a printing press body is fixedly connected to the top of the frame and located above the transmission mechanism, a material storage mechanism is provided at the top of the printing press body, the material storage mechanism is composed of a material storage barrel and a filter box, and the filter box is located above the material storage barrel, a plurality of support frames are vertically fixedly connected to the inner wall of the filter box, a filter frame is slidably connected to the top of the support frame, one end of the filter frame extends to the outside through one side of the filter box and is welded with a handle, a plurality of filter screens are provided at the bottom ends of the filter frames, and the apertures of the plurality of filter screens gradually decrease from top to bottom;

[0008] A material delivery pipe is fixedly connected between the filter box and the storage barrel, and the two are communicated through the material delivery pipe. A first driving motor is fixedly installed on the top of the storage barrel, and an output end of the first driving motor extends to the interior of the storage barrel and is fixedly connected to a first rotating bracket. Two symmetrical support rods are fixedly connected to one side of the first rotating bracket, and one end of the support rod is fixedly connected to a scraper rod, and a side of the scraper rod away from the support rod is in contact with the inner side wall of the storage barrel. A plurality of first prismatic columns are vertically and equidistantly arranged on a side of the first rotating bracket away from the scraper rod;

[0009] A second drive motor is fixedly installed at the bottom end of the storage barrel, the output end of the second drive motor extends to the interior of the storage barrel and is fixedly connected to a stirring rod, the bottom of the first rotating bracket is connected to the outer lower part of the stirring rod through a bearing, one side of the stirring rod is fixedly connected to a second rotating bracket, and a plurality of second prismatic columns are symmetrically arranged on both sides of the second rotating bracket.

[0010] By adopting the above technical solution, the paint first enters the filter box. When the paint enters the filter box from the outside, it will pass through multiple filter frames in sequence for filtering. The aperture of the filter screen in the filter frame gradually decreases from top to bottom. This makes it possible for larger particles of impurities to be first intercepted by the upper filter screen with larger apertures when the paint passes through the filter frame. As the paint continues to flow downward, smaller particles of impurities are filtered in turn by the filter screen with gradually smaller apertures. The filter frame is supported by a support frame and is slidably connected to the support frame, which makes it convenient for staff to regularly pull out the filter frame for cleaning or replacing the filter screen to ensure the continuous and stable filtering effect. The filter frame can be easily pulled out of the filter box by the handle.

[0011] The filtered paint enters the storage barrel through the feed pipe for storage, and the first drive motor at the top of the storage barrel is started to drive the first rotating bracket to rotate. The first prismatic column on the first rotating bracket rotates, which has a certain stirring and turbulent effect on the paint, so that the paint is more evenly distributed in the storage barrel, and the paint is prevented from sedimentation and stratification. The support rod and the scraper rod on one side of the first rotating bracket rotate with the rotation of the first rotating bracket. The scraper rod is always in contact with the inner wall of the storage barrel. During the rotation process, the paint attached to the inner wall of the storage barrel can be scraped off to prevent the paint from drying on the barrel wall, thereby ensuring the effective capacity of the paint in the storage barrel and ensuring that the paint can fully participate in the subsequent stirring and supply process;

[0012] The second drive motor at the bottom of the storage barrel is started, driving the stirring rod to rotate. The second rotating bracket on the stirring rod and the second prismatic columns on both sides also rotate accordingly, further stirring and mixing the paint. The second prismatic columns also play a turbulent role, cooperating with the first prismatic columns on the first rotating bracket to make the paint more fully stirred in the storage barrel, ensuring the uniformity and stability of the paint.

[0013] When the printing machine body needs paint for packaging and decoration printing, the filtered and fully stirred paint in the storage barrel is transported to the printing machine body, and the printing machine body prints the packaging material on the transmission mechanism. In this way, the entire paint supply device provides stable, uniform, and impurity-free paint for packaging and decoration printing, ensuring printing quality.

[0014] Furthermore, the size of the second rotating bracket is smaller than that of the first rotating bracket, and the second rotating bracket is located inside the first rotating bracket.

[0015] By adopting the above technical solution, in the storage barrel, the first rotating bracket and the first prismatic column thereon mainly stir and disturb the paint on a large scale to prevent the paint from settling and stratifying, and clean the inner wall of the storage barrel through the scraper rod, while the second rotating bracket located inside the first rotating bracket can perform more fine stirring in a relatively small space, and the second prismatic columns on both sides cooperate with the first prismatic columns to further improve the uniformity and stability of the paint. This double-layer stirring structure not only ensures the comprehensiveness of the stirring, but also improves the stirring effect, providing better quality paint for packaging, decoration and printing.

[0016] Furthermore, the size of the second prismatic columns is smaller than that of the first prismatic columns, and the second prismatic columns and the first prismatic columns are arranged in an alternating manner.

[0017] By adopting the above technical solution, firstly, the smaller second prismatic columns can, based on the stirring of the first prismatic columns, penetrate into the fine areas of the paint to perform more precise disturbances. When the first prismatic columns stir the paint over a large area, there may be some local areas where the stirring is insufficient. The second prismatic columns can compensate for this deficiency and ensure that every part of the paint is fully mixed.

[0018] Secondly, the staggered arrangement makes the stirring more comprehensive without dead angles. During the rotation of the first prismatic column and the second prismatic column, a complex flow field is formed, in which the paint is constantly disrupted and mixed. This staggered arrangement increases the flow path of the paint and the number of stirring times, greatly improving the uniformity of the paint.

[0019] During the packaging and decoration printing process, this fully stirred and uniform coating can ensure the stable quality of the printed products, and indicators such as color and glossiness are more in line with the requirements, providing a strong guarantee for high-quality packaging and decoration printing.

[0020] Furthermore, a feed port is provided in the middle of the top end of the filter box, and the filter box is connected to the storage barrel through first supporting legs at the four corners of the bottom end.

[0021] By adopting the above technical solution, the paint is poured into the filter box from the feed port and begins to be filtered. The feed port is designed to be located in the middle of the top to facilitate the injection operation of the paint, so that the paint can enter the filter box more evenly, avoiding local accumulation or uneven flow.

[0022] These four first support legs serve to stably support the filter box, ensuring that the filter box does not shake or tilt during operation. At the same time, the setting of the first support legs also maintains a certain distance between the filter box and the storage barrel, making it convenient for the paint to flow smoothly through the feed pipe into the storage barrel under the action of gravity, and providing operating space for possible subsequent maintenance and overhaul work.

[0023] Furthermore, a plurality of second supporting legs are provided in a circular array at the bottom end of the material storage barrel, and the bottom ends of the second supporting legs are connected to the top end of the printer body.

[0024] By adopting the above technical solution, firstly, the multiple second support legs in the annular array can provide stable support for the storage barrel. Since the storage barrel needs to store a certain amount of paint during operation, its own weight plus the weight of the paint may be large. The multiple second support legs are evenly distributed at the bottom of the storage barrel, which can effectively disperse gravity and ensure that the storage barrel can remain stable in various working conditions without tilting or shaking.

[0025] Secondly, the bottom end of the second support leg is connected to the top end of the printer body. This connection makes the structure of the entire paint supply device more compact. On the one hand, the relative position between the storage barrel and the printer body is more fixed, which facilitates the delivery of paint and reduces the problems of distortion and blockage of the delivery pipeline caused by position changes. On the other hand, this connection also saves space, allowing the entire device to operate more efficiently within a limited working space.

[0026] During the packaging and decoration printing process, the stable storage barrel and compact structural design help ensure a stable supply of coating and improve printing efficiency and quality.

[0027] Furthermore, a water pump is fixedly installed on the top of the printer body, the water inlet pipe of the water pump is connected to the material storage cylinder, and the water outlet pipe of the water pump is connected to the printer body.

[0028] By adopting the above technical solution, the water inlet pipe of the water pump is connected with the storage barrel, so that the water pump can extract the filtered and fully stirred paint from the storage barrel. The paint in the storage barrel maintains a certain fluidity under the action of gravity and the internal stirring device, which facilitates the water pump to smoothly extract the paint. The water outlet pipe of the water pump is connected with the printing press body to transport the extracted paint to the printing press body. In this way, during the printing process, the water pump can stably supply the paint to the printing press body at a certain pressure and flow rate according to the needs of the printing press, ensuring the continuous printing operation. Through the action of the water pump, efficient transportation of the paint from the storage barrel to the printing press body is achieved, providing a reliable paint supply guarantee for packaging and decoration printing.

[0029] Compared with the prior art, the present invention has the following beneficial effects:

[0030] (1) The utility model relates to a coating supply device for packaging and decoration printing. A plurality of filter frames are provided in the filter box of the device. The aperture of the filter screen decreases gradually from top to bottom, and impurities of different sized particles can be filtered in turn. This ensures that the coating entering the storage barrel and the printer body is free of impurities, thereby greatly improving the quality of the printed matter and avoiding problems such as surface defects caused by impurities. When printing high-end packaging gift boxes, the surface of the printed matter can be made smooth and delicate, thereby improving the grade of the product. The filter frame is slidably connected to the support frame, which is convenient for the staff to clean or replace the filter screen regularly, thereby ensuring the continuous and stable filtering effect. This reduces frequent equipment maintenance and downtime caused by the decline in filtering effect, thereby improving production efficiency.

[0031] (2) The utility model relates to a coating supply device for packaging and decoration printing. The first rotating bracket and the first prismatic column, the second rotating bracket and the second prismatic column in the storage barrel cooperate with each other to fully stir and disturb the coating, and prevent the coating from sedimentation and stratification. This double-layer stirring structure makes the coating more evenly distributed in the storage barrel, and provides a stable coating supply for the printing press. During long-term printing operations, it can ensure that the quality indicators such as the color and gloss of the printed products are always consistent. The scraper rod can scrape off the coating attached to the inner wall of the storage barrel to avoid the coating from drying up, and ensure the effective capacity of the coating in the storage barrel. This not only reduces the waste of coating, but also ensures that the coating can fully participate in the stirring and supply process, and further improves the utilization rate of the coating and the stability of supply.

[0037] In order to prevent impurities in the coating from affecting the printing quality and causing defects and uneven colors on the printed surface, to prevent the coating from sedimentation and stratification during storage, which makes the coating supplied to the printing press uneven and affects the printing effect, and to prevent the coating from adhering to the inner wall of the storage container, causing coating waste, reducing the effective capacity and affecting subsequent use after drying, so as to improve the quality of printed products, ensure the stability of coating supply, improve the utilization rate of coating and reduce equipment maintenance costs. Figure 1 、 Figure 2 、 Figure 3 As shown, a coating supply device for packaging and decoration printing comprises a frame 1, a transmission mechanism 2 is provided at the top of the frame 1, a printing press body 3 is fixedly connected to the top of the frame 1 and located above the transmission mechanism 2, a storage mechanism 4 is provided at the top of the printing press body 3, the storage mechanism 4 is composed of a storage barrel 5 and a filter box 6, and the filter box 6 is located on the upper part of the storage barrel 5, a plurality of support frames 7 are vertically fixedly connected to the inner wall of the filter box 6, a filter frame 8 is slidably connected to the top of the support frame 7, one end of the filter frame 8 passes through one side of the filter box 6 and extends to the outside, and a handle 9 is welded thereto, a plurality of filter frames 8 are provided with filter screens at the bottom ends, and the apertures of the plurality of filter screens gradually decrease from top to bottom;

[0038] A material delivery pipe 10 is fixedly connected between the filter box 6 and the storage barrel 5, and the two are communicated through the material delivery pipe 10. A first drive motor 11 is fixedly installed on the top of the storage barrel 5. The output end of the first drive motor 11 extends to the interior of the storage barrel 5 and is fixedly connected to a first rotating bracket 12. Two symmetrical support rods 14 are fixedly connected to one side of the first rotating bracket 12. A scraper rod 15 is fixedly connected to one end of the support rod 14. The side of the scraper rod 15 away from the support rod 14 is in contact with the inner side wall of the storage barrel 5. A plurality of first prismatic columns 13 are vertically and equidistantly arranged on the side of the first rotating bracket 12 away from the scraper rod 15.

[0039] A second drive motor 16 is fixedly installed at the bottom end of the storage barrel 5. The output end of the second drive motor 16 extends to the interior of the storage barrel 5 and is fixedly connected to a stirring rod 17. The bottom of the first rotating bracket 12 is connected to the outer lower part of the stirring rod 17 through a bearing. One side of the stirring rod 17 is fixedly connected to a second rotating bracket 18. A plurality of second prismatic columns 19 are symmetrically arranged on both sides of the second rotating bracket 18.

[0040] When in use, the paint first enters the filter box 6. When the paint enters the filter box 6 from the outside, it will pass through multiple filter frames 8 in sequence for filtering. The pore size of the filter screen in the filter frame 8 gradually decreases from top to bottom, so that when the paint passes through the filter frame 8, larger particles of impurities are first intercepted by the upper filter screen with larger pore size. As the paint continues to flow downward, smaller particles of impurities are filtered in turn by the filter screen with gradually smaller pore size. The filter frame 8 is supported by the support frame 7 and is slidably connected to the support frame 7, which makes it convenient for the staff to regularly pull out the filter frame 8 for cleaning or replacing the filter screen to ensure the continuous and stable filtering effect. The filter frame 8 can be easily pulled out of the filter box 6 through the handle 9;

[0041] The filtered paint enters the storage barrel 5 through the delivery pipe 10 for storage, and the first drive motor 11 at the top of the storage barrel 5 is started, driving the first rotating bracket 12 to rotate. The first prismatic column 13 on the first rotating bracket 12 rotates to stir and disturb the paint to a certain extent, so that the paint is more evenly distributed in the storage barrel 5, and the paint is prevented from sedimentation and stratification. The support rod 14 and the scraper rod 15 on one side of the first rotating bracket 12 rotate with the rotation of the first rotating bracket 12. The scraper rod 15 always fits with the inner wall of the storage barrel 5. During the rotation process, the paint attached to the inner wall of the storage barrel 5 can be scraped off to prevent the paint from drying on the barrel wall, thereby ensuring the effective capacity of the paint in the storage barrel 5 and ensuring that the paint can fully participate in the subsequent stirring and supply process;

[0042] The second drive motor 16 at the bottom of the storage barrel 5 is started, driving the stirring rod 17 to rotate, and the second rotating bracket 18 on the stirring rod 17 and the second prismatic columns 19 on both sides also rotate accordingly, further stirring and mixing the paint. The second prismatic columns 19 also play a turbulent role, cooperating with the first prismatic columns 13 on the first rotating bracket 12, so that the paint is more fully stirred in the storage barrel 5, ensuring the uniformity and stability of the paint;

[0043] When the printer body 3 needs paint for packaging and decoration printing, the filtered and fully stirred paint in the storage barrel 5 is transported to the printer body 3, and the printing operation is performed on the packaging material on the transmission mechanism 2 through the printer body 3. In this way, the entire paint supply device provides stable, uniform, and impurity-free paint for packaging and decoration printing, ensuring printing quality.

[0044] For example, Figure 3 As shown, the present invention further includes that the size 18 of the second rotating bracket is smaller than the size of the first rotating bracket 12 , and the second rotating bracket 18 is located inside the first rotating bracket 12 .

[0045] During use, in the storage barrel 5, the first rotating bracket 12 and the first prismatic column 13 thereon mainly stir and disturb the paint on a large scale to prevent the paint from settling and stratifying, and clean the inner wall of the storage barrel 5 through the scraper 15, while the second rotating bracket 18 located on the inner side of the first rotating bracket 12 can perform more fine stirring in a relatively small space, and the second prismatic columns 19 on both sides cooperate with the first prismatic column 13 to further improve the uniformity and stability of the paint. This double-layer stirring structure not only ensures the comprehensiveness of the stirring, but also improves the stirring effect, providing better quality paint for packaging, decoration and printing.

[0046] For example, Figure 3 As shown, the present invention also includes that the size of the second prismatic column 19 is smaller than the size of the first prismatic column 13 , and the second prismatic column 19 and the first prismatic column 13 are arranged in an alternating manner.

[0047] During use, firstly, the smaller second prismatic columns 19 can, based on the stirring of the first prismatic columns 13, penetrate into the fine areas of the paint to perform more precise disturbances. When the first prismatic columns 13 stir the paint over a large area, there may be some local areas where the stirring is insufficient. The second prismatic columns 19 can compensate for this deficiency and ensure that every part of the paint is fully mixed.

[0048] Secondly, the staggered arrangement makes the stirring more comprehensive without dead angles. During the rotation process, the first prismatic column 13 and the second prismatic column 19 form a complex flow field, in which the paint is constantly disrupted and mixed. This staggered arrangement increases the flow path of the paint and the number of stirring times, greatly improving the uniformity of the paint.

[0049] During the packaging and decoration printing process, this fully stirred and uniform coating can ensure the stable quality of the printed products, and indicators such as color and glossiness are more in line with the requirements, providing a strong guarantee for high-quality packaging and decoration printing.

[0050] For example, Figure 2 、 Figure 3 As shown, the present invention further includes that a feed port 20 is provided at the middle of the top end of the filter box 6 , and the filter box 6 is connected to the storage barrel 5 through first supporting legs 21 at the four corners of the bottom end.

[0051] When in use, after the paint is poured into the filter box 6 from the feed port 20, the filtration process begins. The position of the feed port 20 is designed in the middle of the top to facilitate the injection operation of the paint, so that the paint can enter the filter box 6 more evenly, avoiding local accumulation or uneven flow;

[0052] These four first support legs 21 serve to stably support the filter box 6, ensuring that the filter box 6 does not shake or tilt during operation. At the same time, the setting of the first support legs 21 also maintains a certain distance between the filter box 6 and the storage barrel 5, making it convenient for the paint to flow smoothly through the feed pipe 10 into the storage barrel 5 under the action of gravity, and providing operating space for possible subsequent maintenance and overhaul work.

[0053] For example, Figure 2 、 Figure 3 As shown, the present invention further includes that the bottom end of the storage barrel 5 has a plurality of second supporting legs 22 in a circular array, and the bottom ends of the second supporting legs 22 are connected to the top end of the printer body 3 .

[0054] During use, firstly, the plurality of second supporting legs 22 in the annular array can provide stable support for the storage barrel 5. Since the storage barrel 5 needs to store a certain amount of paint during operation, its own weight plus the weight of the paint may be large. The plurality of second supporting legs 22 are evenly distributed at the bottom of the storage barrel 5, which can effectively disperse the gravity and ensure that the storage barrel 5 can remain stable in various working states without tilting or shaking.

[0055] Secondly, the bottom end of the second support leg 22 is connected to the top end of the printer body 3. This connection makes the structure of the entire paint supply device more compact. On the one hand, the relative position between the storage barrel 5 and the printer body 3 is more fixed, which facilitates the delivery of paint and reduces problems such as distortion and blockage of the delivery pipeline caused by position changes. On the other hand, this connection also saves space, allowing the entire device to operate more efficiently within a limited working space.

[0056] During the packaging and decoration printing process, the stable material storage barrel 5 and the compact structural design help to ensure a stable supply of coating material and improve the efficiency and quality of printing.

[0057] For example, Figure 3 As shown, the present invention further includes a water pump 23 fixedly mounted on the top of the printer body 3 , the water inlet pipe of the water pump 23 is connected to the material storage barrel 5 , and the water outlet pipe of the water pump 23 is connected to the printer body 3 .

[0058] When in use, the water inlet pipe of the water pump 23 is connected to the storage barrel 5, so that the water pump 23 can extract the filtered and fully stirred paint from the storage barrel 5. The paint in the storage barrel 5 maintains a certain fluidity under the action of gravity and the internal stirring device, which facilitates the water pump 23 to smoothly extract the paint. The water outlet pipe of the water pump 23 is connected to the printing press body 3 to transport the extracted paint to the printing press body 3. In this way, during the printing process, the water pump 23 can stably supply the paint to the printing press body 3 at a certain pressure and flow rate according to the needs of the printing press, ensuring the continuous printing operation. Through the action of the water pump 23, the efficient transportation of the paint from the storage barrel 5 to the printing press body 3 is achieved, providing a reliable paint supply guarantee for packaging and decoration printing.

[0059] It should be noted that the present invention is a coating supply device for packaging and decoration printing. The coating is slowly poured into the filter box 6 from the feed port 20 at the top middle of the filter box 6. After the coating enters the filter box 6, it will pass through multiple filter frames 8 in sequence for filtration. Larger particles of impurities are first intercepted by the upper filter screen with larger pore size. As the coating continues to flow downward, smaller particles of impurities are filtered in sequence by the filter screens with gradually smaller pore sizes. The filtration condition of the filter frame 8 is checked regularly. If it is found that the filtration speed is significantly slowed down or a lot of impurities are accumulated in the filter frame 8, the operation of the device can be suspended, and the filter frame 8 can be pulled out of the filter box 6 by the handle 9 to clean or replace the filter screen.

[0060] The filtered paint flows smoothly into the storage barrel 5 for storage through the feed pipe 10 under the action of gravity. The first drive motor 11 at the top of the storage barrel 5 and the second drive motor 16 at the bottom are turned on. The first drive motor 11 drives the first rotating bracket 12 to rotate, and the first prismatic column 13 stirs and turbules the paint in a large range. At the same time, the support rod 14 and the scraper rod 15 rotate, and the scraper rod 15 scrapes the paint on the inner wall of the storage barrel 5 to prevent it from drying out; the second drive motor 16 drives the stirring rod 17 to rotate, and the second rotating bracket 18 and the second prismatic columns 19 on both sides also rotate accordingly, cooperating with the first prismatic column 13 to further stir and mix the paint to ensure the uniformity and stability of the paint;

[0061] When the printer body 3 needs paint for packaging and decoration printing, the water pump 23 is started, and the water inlet pipe of the water pump 23 draws the filtered and fully stirred paint from the storage barrel 5. Under the action of gravity and the internal stirring device, the paint maintains a certain fluidity, which is convenient for the water pump 23 to smoothly extract it, and the water outlet pipe of the water pump 23 transports the paint to the printer body 3.
