Description

Technical Field

[0001] The invention relates to the technical field of printing machines, in particular to an ink supply device of a printing machine. Background Art

[0002] Cement is indispensable in house construction. After production, cement needs to be packed and transported. The packaging bags for cement are sturdy woven bags. During the production process of cement woven bags, corresponding logos need to be marked on the surface of the cement woven bags. The content of the logo not only includes the functions and performance of the cement woven bags, but also the different manufacturers. Therefore, it is necessary to use the corresponding printing machine to print the corresponding logo on it.

[0003] However, today's printing presses often supply ink by ink coating. The ink of existing printing presses directly enters the printing press through the ink inlet tube. After the ink enters the printing press, some components of the ink precipitate and condense into lumps, and the residue adheres to the inner wall of the machine body, which leads to blockage of the ink outlet tube, gradually reducing the ink supply, making the printed pattern incomplete and unclear, affecting the normal printing effect of the printing press. At the same time, for the ink, some components of the ink condense into lumps and cannot be used normally, resulting in unnecessary waste of ink and increased production costs. Summary of the invention

[0004] In view of the deficiencies of the prior art, the present invention provides an ink supply device for a printing press to solve the problem mentioned in the background art that the ink directly enters the printing press and the ink outlet tube is blocked by residues, thus affecting the normal printing effect of the printing press.

[0010] Preferably, a push plate is threadedly mounted on the screw rod, four groups of connecting rods are equidistantly mounted on the push plate, and the bottom ends of the connecting rods are fixedly connected to the surface of the connecting cover.

[0011] Preferably, the printing assembly includes a shell fixedly connected to the bottom of the guide tube, two groups of limit members are symmetrically installed in the shell, multiple groups of springs are equidistantly arranged on the limit members, a printing plate is arranged between the two groups of limit members, and the printing plate is fixedly connected to the limit members through springs.

[0012] Preferably, the cross-sectional shape of the limiting member in a side view is L-shaped, and a rubber pad is fixedly connected to the bottom of the limiting member.

[0013] Preferably, six groups of telescopic rods are equidistantly fixedly installed in a circular shape at the bottom of the ink cartridge, and the bottom ends of the telescopic rods are fixedly connected to the surface of the outer shell.

[0016] Preferably, the ink cartridge is provided with an ink filling valve.

[0017] By means of the above technical solution, the present invention provides an ink supply device for a printing press, which has at least the following beneficial effects:

[0018] 1. The ink supply device of the printing press, by providing an ink supply component, a stirring component and a printing component, allows the ink to enter the printing press in a quantitative, smooth and fast manner, thereby preventing excessive unnecessary ink from directly entering the printing press during the printing operation and condensing into lumps in the printing press to block the ink outlet tube.

[0019] 2. The ink supply device of the printing press is provided with an ink supply component, and the guide tube moves up and down in the ink cartridge, so that the inkjet ball releases a certain amount of ink when the printing component contacts the woven bag, thereby preventing a large amount of ink from directly entering the printing press and allowing the ink to flow out smoothly. It is also helpful for the efficient use of ink, ensuring the smooth ink discharge of the ink outlet tube and the printing effect of the printing press.

[0020] 3. The ink supply device of the printing press is provided with a stirring component. Under the rotation of the scraper, the inner wall of the ink cartridge is scraped and stirred to prevent the ink from condensing and hanging on the wall in the ink cartridge, which increases the ink impurity rate. The spiral plate is driven by the screw to stir the ink in the ink cartridge in all aspects, and at the same time enhances the fluidity of the ink. When the ink supply component opens the channel connecting with the ink cartridge, the ink can quickly enter the ink supply component.

[0021] 4. The ink supply device of the printing machine, by setting up printing components, rollers and rubber pads to flatten and fix the woven bags, avoids slipping when the printing plate contacts or separates from the woven bags during the printing process, thereby blurring the printing effect. The setting of the spring allows the printing plate to have a buffer during the ink filling and printing process, avoiding the sprayed ink from being directly printed on the woven bag through the printing plate, causing excessive ink on the woven bag and affecting the printing effect.

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] An ink supply device for a printing press provided by some embodiments of the present invention will be described below in conjunction with the accompanying drawings.

[0033] Embodiment 1:

[0034] Combination Figure 1-Figure 6 As shown, an ink supply device of a printing press provided by the present invention includes a workbench 1 for supporting the printing press, a lifting component 2 for driving the printing press is arranged on the workbench 1, a stirring component 3 for providing ink is arranged on the lifting component 2, an ink supply component 4 for controlling the circulation of ink is arranged below the stirring component 3, a printing component 5 for printing is arranged below the ink supply component 4, the lifting component 2 drives the stirring component 3, the ink supply component 4 and the printing component 5 to move up and down, and the printing component 5 controls the ink supply component 4 to release ink from the stirring component 3 after contacting the woven bag, so that the ink enters the printing component 5 quantitatively, smoothly and quickly, avoiding excessive unnecessary ink directly entering the printing component 5 during the printing operation, and condensing into blocks in the printing component 5 to block the ink outlet pipe, and is beneficial to improving the utilization rate of the ink, reducing the probability of ink agglomeration, and thus reducing the possibility of unnecessary waste of ink.

[0035] The ink supply component 4 includes a guide tube 402 slidably inserted in the stirring component 3, the top of the guide tube 402 is fixedly connected to a connecting cover 401, four groups of flow ports 403 are equidistantly provided in a ring shape on the guide tube 402, a speed control funnel 404 is fixedly installed inside the guide tube 402, and an inkjet ball 405 is fixedly installed at the bottom of the speed control funnel 404, the guide tube 402 slides relatively along the central hole in the stirring component 3, the flow port 403 is aligned with the filter 406, the ink enters the speed control funnel 404 from the filter 406 through the flow port 403, and then splashes from the inkjet ball 405 onto the printing plate 505, in the process of the guide tube 402 quickly sliding to open and close the flow channel, the amount of ink splashed by the inkjet ball 405 is controlled, avoiding the possibility of a large amount of ink directly connecting with the printing plate 505, and at the same time increasing the fluidity of the ink, so as to achieve the purpose of making the ink flow out smoothly, thereby ensuring the smooth ink discharge of the ink outlet tube and the printing effect of the printing press.

[0036] Specifically, the stirring component 3 includes an ink cartridge 301 arranged outside the connecting cover 401, a center hole is opened at the bottom of the ink cartridge 301, a filter screen 406 is fixedly installed outside the center hole in the ink cartridge 301, a dustproof plate 407 is fixedly installed at the bottom of the stirring component 3, the ink cartridge 301 stores ink to prevent the ink from being directly placed in the printing component 5, the guide tube 402 is slidably inserted in the center hole, the filter screen 406 filters the ink to flow into the ink supply component 4 to prevent the ink residue from flowing onto the printing plate 505 and affecting the printing effect of the printing press, after the flow port 403 is separated from the filter screen 406, the dustproof plate 407 prevents the flow port 403 from being directly exposed outside the entire device, and isolates the dust and other powder in the air from entering the printing component 5 through the speed control funnel 404 to increase the impurities in the ink.

[0037] Furthermore, the printing assembly 5 includes a shell 501 fixedly connected to the bottom of the guide tube 402, two groups of limit members 502 are symmetrically installed in the shell 501, multiple groups of springs 504 are equidistantly arranged on the limit members 502, a printing plate 505 is arranged between the two groups of limit members 502, and the printing plate 505 is fixedly connected to the limit members 502 through the springs 504, six groups of telescopic rods 506 are equidistantly fixedly installed in a ring shape at the bottom end of the ink cartridge 301, and the bottom ends of the telescopic rods 506 are fixedly connected to the surface of the shell 501, four groups of connecting rods 507 are equidistantly fixedly installed in a rectangular shape at the bottom end of the ink cartridge 301, and the bottom ends of the connecting rods 507 pass through the shell 501 and are fixedly connected to the printing plate 505.

[0038] After the limiter 502 contacts the woven bag, the flow port 403 is aligned with the filter screen 406, and the inkjet ball 405 splashes onto the printing plate 505. The stirring component 3 continues to press down, and the connecting rod 507 applies pressure to the printing plate 505, thereby squeezing the spring 504, and squeezing the protruding surface of the printing plate 505 out of the horizontal plane of the rubber pad 503, so that the bottom surface of the printing plate 505 contacts the surface of the woven bag, and the woven bag is imprinted. After the imprinting of the printing plate 505 is completed, the upward movement of the ink cartridge 301 causes the connecting rod 507 to immediately release the pressure on the printing plate 505, and the spring 504 immediately pushes the printing plate 505 back to its original position due to its elasticity, that is, the printing plate 505 leaves the surface of the woven bag. The setting of the spring 504 provides a buffer for the printing plate 505 during the ink filling and printing process, thereby preventing the sprayed ink from being directly printed on the woven bag through the printing plate 505, causing too much ink on the woven bag, affecting the printing effect, and accelerating the recovery of the printing plate 505, thereby preventing the printing plate 505 from blurring the woven bag printing.

[0039] Furthermore, the lifting component 2 includes a hydraulic cylinder 201 fixedly installed on the workbench 1, a limiting pipe 202 fixedly installed on the hydraulic cylinder 201, a sliding block 203 slidably installed in the limiting pipe 202, a connecting piece 204 fixedly connected to the sliding block 203, and the connecting piece 204 is fixedly connected to the ink cartridge 301, driving the hydraulic cylinder 201 to control the sliding block 203 to slide up and down along the inner wall of the limiting pipe 202. When the printing plate 505 prints the woven bag, the hydraulic cylinder 201 controls the sliding block 203 to move up and down, and the sliding block 203 controls the stirring component 3 to move accordingly through the connecting piece 204, thereby printing the woven bag together with the ink supply component 4 and the printing component 5.

[0040] According to the embodiment, the woven bag is placed in a fixed position on the workbench 1, and the hydraulic cylinder 201 is driven to control the sliding block 203 to slide up and down along the inner wall of the limiting pipe 202. When the printing plate 505 prints the woven bag, the hydraulic cylinder 201 controls the sliding block 203 to slide down, and the sliding block 203 controls the stirring component 3 to move downward through the connecting piece 204, and the ink supply component 4 and the printing component 5 are moved downward. When the printing component 5 contacts the woven bag, the printing component 5 fixes and presses the woven bag, and the stirring component 3 continues to move downward. The flow guide tube 402 slides relatively along the central hole in the stirring component 3, the flow port 403 is aligned with the filter screen 406, and the ink enters the speed control funnel 404 from the filter screen 406 through the flow port 403, and then splashes from the inkjet ball 405 to the printing plate 505. When the stirring component 3 continues to be pressed down, the connecting rod 507 exerts pressure on the printing plate 505, and then squeezes the spring 504, and squeezes the protruding surface of the printing plate 505 out of the horizontal plane of the rubber pad 503, so that the bottom surface of the printing plate 505 contacts the surface of the woven bag, and the woven bag is printed.

[0041] After the printing plate 505 is imprinted, the hydraulic cylinder 201 immediately controls the sliding block 203 to move upward along the inner wall of the limiting pipe 202, thereby controlling the stirring component 3, the ink supply component 4 and the printing component 5 to move upward. When the stirring component 3 moves upward, the upward movement of the ink cartridge 301 causes the connecting rod 507 to immediately release the pressure on the printing plate 505, and the spring 504 quickly pushes the printing plate 505 back to its original position due to its elasticity, that is, the printing plate 505 leaves the surface of the woven bag. During the upward movement of the stirring component 3, the guide tube 402 moves downward relatively along the center hole of the ink cartridge 301, the flow port 403 and the filter screen 406 are misaligned, and the ink flow channel is closed, that is, the ink supply stops, and the lifting component 2 controls the ink supply device to return to its original position, that is, one printing is completed.

[0042] Embodiment 2:

[0043] Combination Figure 1 , Figure 3 and Figure 4 As shown, a screw rod 302 is rotatably installed in the ink cartridge 301, a rotating disk 303 is fixedly connected to the screw rod 302, a plurality of stirring rods 304 are equidistantly installed in an annular manner on the rotating disk 303, a scraper 305 is fixedly installed on the stirring rod 304, a spiral plate 306 is rotatably installed at the center of the stirring rod 304, a push plate 307 is threadedly installed on the screw rod 302, four groups of connecting rods 308 are equidistantly installed on the push plate 307, and the bottom ends of the connecting rods 308 are fixedly connected to the surface of the connecting cover 401, an ink filling valve 309 is provided on the ink cartridge 301, and a screw rod 308 is fixedly connected to the surface of the connecting cover 4 ... As the scraper 305 rotates, the inner wall of the ink cartridge 301 is scraped and stirred to prevent the ink from condensing and hanging on the wall in the ink cartridge 301, which increases the ink impurity rate. The spiral plate 306, driven by the screw rod 302, stirs the ink in the ink cartridge 301 in all aspects and enhances the fluidity of the ink. When the ink supply component 4 opens the channel connecting to the ink cartridge 301, the ink can quickly enter the ink supply component 4. The ink adding valve 309 allows the operator to add ink in time, avoiding repeated disassembly and installation of the ink cartridge 301 and reducing the generation of complicated operating procedures.

[0044] According to the embodiment, when the ink supply component 4 moves upward relative to the stirring component 3, the connecting cover 401 pushes the push plate 307 to rotate and move upward along the screw rod 302 through the connecting rod 308. Due to the threaded cooperation between the push plate 307 and the screw rod 302, the screw rod 302 rotates at the same time, and the turntable 303 rotates accordingly. The stirring rod 304 on the turntable 303 is driven to move, and then the scraper 305 on the stirring rod 304 scrapes the wall of the ink cartridge 301 to prevent the ink from solidifying on the inner wall of the ink cartridge 301. The movement of the stirring rod 304 drives the spiral plate 306, and the moving spiral plate 306 stirs the ink in the ink cartridge 301. While preventing the ink from solidifying, it accelerates the flow of the ink, which helps the ink to quickly pass through the filter screen 406 into the ink supply component 4. When the ink in the ink cartridge 301 is about to be exhausted, ink can be added to the ink cartridge 301 through the ink adding valve 309.

[0045] Embodiment three:

[0046] Combination Figure 1 , Figure 4-Figure 6 As shown, two groups of connecting shafts 508 are fixedly installed in the outer shell 501, and the two groups of connecting shafts 508 are respectively located on the outside of the two groups of outer shells 501, a connecting piece 509 is rotatably sleeved on the connecting shaft 508, and a roller 510 is fixedly installed on the protruding end of the connecting piece 509. The cross-sectional shape of the limit member 502 when viewed from the side is L-shaped, and a rubber pad 503 is fixedly connected to the bottom of the limit member 502. The roller 510 and the rubber pad 503 flatten the woven bag and fix it to avoid slipping when the printing plate 505 contacts or separates from the woven bag during the printing process, thereby blurring the printing effect.

[0047] According to the embodiment, when the printing component 5 descends, the two groups of rollers 510 first contact the woven bag. During the sliding of the printing component 5, the two groups of rollers 510 rotate along the connecting shaft 508 through the connecting piece 509, and the rollers 510 spread out to both sides along the surface of the woven bag to flatly spread out the woven bag. The printing component 5 continues to slide down, and the rubber pad 503 contacts the woven bag to further fix and press the woven bag to prevent the woven bag from slipping and deviating during the pressing process of the printing plate 505, and at the same time prevent the limiter 502 from directly colliding with the woven bag to cause indentation or even damage to the woven bag.

[0048] It should be noted that the terms "comprises", "includes" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or apparatus that includes a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or apparatus.

[0049] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
