Description

Technical Field

[0001] The invention belongs to the technical field of printing and processing, and in particular relates to a printing and processing device for packaging films. Background Art

[0002] Screen printing refers to using a silk screen as a base and making a screen printing plate with images through a photosensitive platemaking method. Screen printing consists of five major elements: screen printing plate, scraper, ink, printing table and substrate. Printing is based on the basic principle that the mesh holes of the image part of the screen printing plate can pass the ink, while the mesh holes of the non-image part cannot pass the ink. When printing, pour ink on one end of the screen printing plate, use a scraper to apply a certain pressure to the ink part on the screen printing plate, and move at a constant speed toward the other end of the screen printing plate. During the movement, the ink is squeezed from the mesh holes of the image part to the substrate by the scraper.

[0003] Particle ink uses small particles of ink to print images and text, including photo printing, publication printing and label printing, etc. Since particle ink can produce higher quality images, particle ink can make the particles in the special ink be printed evenly and orderly on the substrate through the special ink formulated, and the ink particles are formed at one time, but because the amount of ink used in each printing is small, most of the ink will accumulate and the particles in the ink will precipitate during the accumulation process, causing the particles to accumulate at the bottom of the ink, and then the ink and particles are unevenly mixed in the subsequent printing, affecting the printing effect, so it needs to be improved.

DETAILED DESCRIPTION

[0034] In order to enable those skilled in the art to better understand the present invention, the technical solution of the present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0035] Example 1: Figure 1-13As shown, the printing and processing device of the packaging film of the present invention comprises a printing machine body 1, the printing machine body 1 comprises a frame 11, a printing table 12, a driving mechanism 13 and a printing substrate 14, the driving mechanism 13 is slidably connected to a clamping assembly 15 matching the printing substrate 14 up and down, the frame 11 is slidably connected to a printing mechanism left and right, the printing mechanism comprises a mounting box 16 slidably connected to the frame 11 left and right, the mounting box 16 is equipped with two adjustment assemblies, the lower ends of the two adjustment assemblies are respectively fixedly connected to a first mounting plate 171 and a second mounting plate 17 slidably connected to the mounting box 16, a scraper 18 is installed in the middle of the first mounting plate 171, a scraper 19 is installed on the side of the second mounting plate 17 away from the scraper 18, the upper ends of the two adjustment assemblies are respectively equipped with telescopic cylinders 20 connected to the second mounting plate 17, a temporary storage trough 21 is provided inside the second mounting plate 17, a discharge port 22 connected to the temporary storage trough 21 is installed at the lower end of the second mounting plate 17, and suction assemblies are installed on the front and rear sides of the second mounting plate 17;

[0036] The material suction assembly includes a sliding block 23 fixedly connected to the first mounting plate 171, the sliding block 23 is fixedly mounted with a material suction nozzle 24 slidably connected to the second mounting plate 17, and the material suction nozzle 24 is connected to the temporary storage tank 21 through a connecting assembly;

[0037] The connecting component includes a connecting pipe 25 installed with the suction nozzle 24, a first gear ring 26 is fixedly connected to the peripheral side of the connecting pipe 25, a blocking member is installed when the connecting pipe 25 extends into the temporary storage trough 21, a rotating shaft 27 is rotatably connected inside the temporary storage trough 12, a stirring member is fixedly connected to the peripheral side of the rotating shaft 27, a gear 28 matching the first gear ring 26 is fixedly installed on the rotating shaft 27, and a suction pump 29 connected to the temporary storage trough 21 is installed on the second mounting plate 17.

[0038] When in use, the packaging film passes through the upper end of the printing table 12, and then the matching printed substrate 14 is clamped by the clamping assembly 15, and then the clamping assembly 15 and the printed substrate 14 are driven up and down by the driving mechanism 13, and then close to the printing table 12, so that the packaging film is driven to move by the external film rolling device, and then the printing mechanism prints the ink of the printed substrate 14 on the packaging film, and then the external film rolling device drives the packaging film to move so that the next packaging film is aligned with the printed substrate 14, and then the printing mechanism is operated to print, and this is repeated until the packaging film is printed. At the same time, the distance between the first mounting plate 171 and the second mounting plate 17 and the printed substrate 14 before starting can also be adjusted by the adjustment component.

[0039] When printing, the special ink is first filled into the temporary storage tank 21 and the printed substrate 14, and the temporary storage tank 21 is half filled, and then the first mounting plate 171 and the scraper 18 are driven downward by the telescopic cylinder 20, so that the first mounting plate 171 drives the two suction components slidably connected with the second mounting plate 17 to move downward, so that the scraper 18 scrapes the printed substrate 14 and the suction pump 29 is started to suck the air inside the temporary storage tank 21, so that the connecting pipe 25 connected with the temporary storage tank 21 passes through the suction nozzle 2 The special ink accumulated on both sides of the upper end of the printed substrate 14 is sucked to enter the temporary storage tank 21. After the scraper 18 has finished scraping, the first mounting plate 171 is driven upward by the telescopic cylinder 20, and the second mounting plate 17 is driven downward by another telescopic cylinder 20, and the suction nozzle 24 is moved upward relative to the second mounting plate 17. In this way, the connecting pipe 25 is blocked by the blocking member and the discharge port 22 is opened. At this time, the temporary storage tank 21 is inflated by the suction pump 29, so that the temporary storage tank is filled with air. The ink inside 21 is squeezed out from the slender discharge port 22 under the action of the suction pump 29 and acts on the center of the printing substrate 14. At the same time, the transmission mechanism 13 drives the printing mechanism to move to the left, so that the ink acting on the upper end of the printing substrate 14 will be spread and filled in the gap of the printing substrate 14 under the action of the scraper 19, until the leftward movement is completed. The two telescopic cylinders 20 respectively drive the first mounting plate 171 to move downward and the second mounting plate 17 to move upward, so that the scraper 18 will abut against the printing substrate 14 and the scraper 19 will be away from the printing substrate 14. In this way, the printing machine can move to the right and print the ink on the surface of the packaging film through the scraper 18. Similarly, the first gear ring 26 will be driven downward and meshed with the gear 28 during the downward movement of the suction component, and the gear 28 will be driven to rotate during the continuous downward movement of the first gear ring 26. In this way, the ink inside the temporary storage tank 21 will be mixed through the stirring member to prevent the particles from precipitating during the static process of the ink containing particles, thereby causing uneven ink particle content.

[0040] The present invention can suck the special ink accumulated on both sides of the printing substrate through the suction component, and then allow the excess ink to enter the temporary storage tank and be mixed through the stirring element, thereby preventing the particles of the special ink from precipitating during the static process and affecting the printing uniformity of the particle ink, thereby affecting the printing effect.

[0041] Embodiment 2: Further improvement is made on the basis of Embodiment 1, the adjustment component includes a lifting plate 31 transmission connected to the output end of the telescopic cylinder 20, the lifting plate 31 is fixedly installed with a threaded barrel 32 slidingly connected to the mounting box 16, the threaded barrel 32 is threadedly connected with a threaded rod 33, and the threaded rod 33 is rotatably installed with the first mounting plate 171 or the second mounting plate 17.

[0042] The telescopic cylinder 20 is used to control the lifting plate 31 and the threaded tube 32 to slide up and down, and the threaded rod 33 is used to fine-tune the distance between the first mounting plate 171 and the second mounting plate 17 and the threaded tube 32, so that the scraper 18 and the scraper 19 can be accurately located at the desired position when the telescopic cylinder 20 is controlled.

[0043] The blocking member includes a blocking block 34 that is slidably connected to the temporary storage trough 21, the blocking block 34 is slidably connected to a sleeve 35 that is sealingly and slidably connected to the connecting pipe 25, a rectangular block 36 is fixedly installed on the outside of the sleeve 35, the sleeve 35 and the connecting pipe 25 are slidably provided with an abutment frame 37, a first spring 38 is provided between the rectangular block 36 and the abutment frame 37, the blocking block 34 is provided with a sliding groove that is sealingly and slidably connected to the sleeve 35, a discharge groove 39 that is connected to the sliding groove is provided on the side of the blocking block 34, and a travel groove 30 that matches the rectangular block 36 is provided inside the second mounting plate 17.

[0044] When the connecting pipe 25 is connected to the temporary storage tank 21, the blocking block 34 abuts against the lower side wall of the temporary storage tank 21, and the rectangular block 36 is located at the lower side of the hypotenuse of the travel groove 30. The rectangular block 36 compresses the first spring 38 to make the sleeve 35 slide into the connecting pipe 25 and leak out of the discharge tank 39. At the same time, the blocking block 34 seals and blocks the travel groove 30.

[0045] When the suction assembly drives the connecting tube 25 to move upward, the connecting tube 25 will drive the sleeve 35, the rectangular block 36, and the blocking block 34 to move upward. At this time, the rebound force of the first spring 38 will make the rectangular block 36 close to the blocking block 34. At this time, the rectangular block 36 will drive the sleeve 35 to slide into the blocking block 34, and then the sleeve 35 will seal the discharge slot 39 during the sliding process inside the sliding slot. During the transition between these two states, the abutment frame 37 always maintains abutment with the connecting tube 25.

[0046] A fixed shaft 40 coaxially arranged with the sleeve 35 and the connecting pipe 25 is fixedly connected inside the sliding groove, and a plurality of spiral feeding plates 41 are fixedly connected to the circumference of the fixed shaft 40 . The sleeve 35 and the connecting pipe 25 are axially slidably connected.

[0047] Since the sleeve 35 and the connecting pipe 25 can only slide axially, when the connecting pipe 25 rotates, the sleeve 35 rotates accordingly, and then cooperates with the stationary spiral feed plate 41 to transport the raw materials inside the sleeve 35 to the direction of the spiral feed plate 41, that is, the discharge trough 39.

[0048] A seal is installed between the blocking block 34 and the discharge port 22, and the seal includes a magnet plate 42 that is sealingly and slidingly connected to the second mounting plate 17, a second spring 43 is installed between the magnet plate 42 and the second mounting plate 17, and the magnet plate 42 has an opening that matches the discharge port 22. The lower end of the blocking block 34 is fixedly connected to a magnet block 44 with an opposite magnetic pole to the magnet plate 42.

[0049] When the blocking block 34 abuts against the temporary storage trough 21, the magnet block 44 is parallel to the magnet plate 42, and the repulsive force between the magnet block 44 and the magnet plate 42 overcomes the second spring 43, so that the magnet plate 42 moves away from the magnet block 44, and the opening of the magnet plate 42 is aligned with the discharge port 22, so that the material can be squeezed out through the suction pump 29 in cooperation with the discharge port 22.

[0050] When the blocking block 34 moves upward and away from the magnet plate 42 , the magnet plate 42 will extend outward under the resilience of the second spring 43 , and the magnet plate 42 will block the discharge port 22 .

[0051] The stirring member includes a plurality of stirring plates 45 fixedly mounted on the rotating shaft 27 . The stirring plates 45 are provided with a plurality of through grooves. A pushing groove 46 is provided at a position where the rotating shaft 27 matches the discharge groove 39 .

[0052] When the discharge trough 39 continuously sucks material under the action of the suction pump 29, it will preferentially act on the inside of the push groove 46 when continuously discharging material from the discharge trough 39, and then apply force to the push groove 46. In this way, the rotating shaft 46 can rotate under the action of the push groove 46, and then drive the stirring plate 45 to rotate to mix the particle ink.

[0053] A material blocking plate 47 is rotatably connected to the lower side of the suction nozzle 24, and extension shafts 48 are fixedly installed in the center of both sides of the material blocking plate 47, one of the extension shafts 48 is transmission connected to a coil spring 49, and the other extension shaft 48 is fixedly installed with a first sprocket 50, and a second sprocket 51 is installed on the upper side of the suction nozzle 24, and a chain 52 is transmission connected between the first sprocket 50 and the second sprocket 51, and a connecting gear 53 is coaxially installed on the second sprocket 51, and the second mounting plate 17 is provided with an engaging lock groove 54 matching the connecting gear 53.

[0054] When the suction assembly is not working, the blocking plate 47 seals the opening of the suction nozzle 24 in the natural state of the coil spring 49. When the sliding block 23 of the suction assembly slides downward, it drives the second sprocket 51 and the connecting gear 53 to move downward, so that the connecting gear 53 contacts the meshing lock groove 54, and the suction nozzle 24 moves downward to drive the connecting gear 53 to rotate, and the second sprocket 51, the chain 52 and the first sprocket 50 are driven to rotate through the connecting gear 53, and the rotation of the first sprocket 50 drives the extension shaft 48 The material blocking plate 47 overcomes the resilience of the coil spring 49 and rotates until the material blocking plate 47 rotates ninety degrees. At this time, the connecting gear 53 is in engagement with the meshing lock groove 54, and the sliding block 23 slides to the lowest point of the second mounting plate 17. At this time, the meshing lock groove 54 will lock the connecting gear 53, and then lock the first sprocket 50 and the material blocking plate 47 to suck through the gap formed by the material blocking plate 47 and the suction nozzle 24. When the suction assembly moves upward, the sealing state will be restored under the resilience of the coil spring 49.

[0055] The connecting pipe 25 is fixedly mounted with a ratchet 55, and the suction nozzle 24 is elastically connected with a ratchet 56 that matches the ratchet 55. The ratchet 55 and the ratchet 56 cooperate to make the connecting pipe 25 rotate in one direction only. Figure 7 For example, the shaft 27 rotates counterclockwise under the action of the pushing groove 46, thereby driving the first toothed ring 26 to rotate clockwise, that is, the ratchet 55 and the pawl 56 can only make the connecting tube 25 rotate clockwise, so when the connecting tube 25 slides from top to bottom, it will preferentially engage with the gear 28. Since the connecting tube 25 can only rotate clockwise, it cannot rotate counterclockwise when engaging with the first toothed ring 26, and thus can only make the gear 28 rotate clockwise, thereby driving the agitator to rotate clockwise, and the pushing groove 46 drives the shaft 27 to rotate counterclockwise, thereby driving the first toothed ring 26 and the connecting tube 25 clockwise through the gear 28.

[0056] A material storage tank 57 is provided inside the installation box 16, and a solenoid valve is used between the material storage tank 57 and the temporary material storage tank 21. A liquid level sensor 58 is installed inside the temporary material storage tank 21. When the liquid level sensor 58 finds that the ink is less than half of the temporary material storage tank 21, the ink inside the material storage tank 57 is put into the temporary material storage tank 21 through the solenoid valve.

[0057] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the technology may modify or change the above embodiments without violating the spirit and scope of the present invention. Therefore, all equivalent modifications or changes made by those with ordinary knowledge in the technical field without departing from the spirit and technical ideas disclosed by the present invention should still be covered by the claims of the present invention.
