Description

Technical Field

[0001] The invention relates to the technical field of inks, in particular to a varnishing varnish for tipping paper and a processing device. Background Art

[0002] Glazing ink is a liquid used to increase the gloss of paper prints. It uses water as a carrier and is applied online by a printing press or offline by a glazing machine to improve the gloss, water resistance, and abrasion resistance of paper prints. The application of this ink has promoted the popularization of coating glazing technology, which in turn has led to a continuous increase in the demand for glazing oil. The use of glazing ink not only enhances the beauty of printed products, but also provides an additional protective layer, which helps to extend the life of printed products.

[0003] In the prior art, antibacterial glazing varnish for cigarette tipping paper uses nano colloidal silver particles as the main antibacterial material, which can effectively prevent bacterial growth and protect printed materials from bacterial contamination, thereby keeping the printed materials clean and hygienic; however, there is still room for improvement in glazing varnish, such as improving the lubricity of cigarette filters; the reason is that when smokers smoke, their lips easily stick to the cigarette filters, and if there is dead skin on the smokers' lips, when the smokers take off the cigarette, the dead skin may be torn, causing the smokers' lips to be torn. This problem is particularly obvious in cold weather such as winter. Summary of the invention

[0022] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0023] See also Figure 1-10 The embodiment of the present invention provides a varnish for tipping paper, comprising the following components: by weight: 56-60 parts of resin liquid; 8-12 parts of nano colloidal silver pre-dispersion liquid; 5-15 parts of polytetrafluoroethylene wax slurry; 10-20 parts of ethanol; 17-20 parts of polytetrafluoroethylene wax; the resin liquid is prepared by mixing dipropylene glycol methyl ether, dimethyl carbonate, epoxy soybean oil, wood pulp nitrocellulose and ethanol; the polytetrafluoroethylene wax slurry is prepared by mixing polytetrafluoroethylene wax with the resin liquid and ethanol.

[0024] It should be mentioned that in the prior art, when grinding the ink, it is often necessary to grind it multiple times to obtain ink with smaller particles. Multiple grindings can improve the fluidity and uniformity of the ink. Then, during the grinding process, a scraper is needed to manually scrape the ink that has been ground once, and knock the scraped ink between the two grinding rollers 23, which is then ground a second time by the grinding rollers 23. This is time-consuming and labor-intensive, and the ink processing efficiency is greatly reduced.

[0025] A processing device, which is used to process the above-mentioned varnishing oil for tipping paper, comprises: a frame 1; a grinding mechanism 2, which comprises a grinding box 21 fixedly connected to the frame 1, a feeding port 22 is opened at the bottom of the grinding box 21, and a plurality of grinding rollers 23 are rotatably connected in the grinding box 21.

[0026] The grinding mechanism 2 is consistent with the prior art, and adopts three grinding rollers 23 , two of which are respectively rotated and abutted, and the other grinding roller 23 is located in the middle and lower position of the above two grinding rollers 23 ; the ink is ground by multiple grinding rollers 23 .

[0027] The material receiving mechanism 3 is used to receive the ground ink flowing out of the discharge port 22; it includes two material receiving components, each of which includes a material receiving box 37, specifically, the material receiving box 37 is semi-cylindrical; the two material receiving boxes 37 are abutted and matched, and the two material receiving boxes 37 are slidably and rotatably connected to the frame 1, and the two material receiving boxes 37 have a material receiving station, a material return stroke, and a material dump stroke in the sliding stroke on the frame 1; At the material receiving station: two material receiving boxes 37 are alternately located below the material discharge port 22 to receive the ground ink at the material discharge port 22; when one of the material receiving boxes 37 is located at the material receiving station, the other material receiving box 37 starts the material return stroke; In the material return stroke: the material receiving box 37 slides on the frame 1 toward the top of the grinding box 21; In the material pouring stroke: the material receiving box 37 rotates on the top of the grinding box 21 so that the ink in the material receiving box 37 is poured back between the grinding rollers 23 for re-grinding.

[0028] Specifically, the material receiving mechanism 3 also includes a moving frame 31 that is laterally slidably connected to the frame 1, and the moving frame 31 has a sliding platform 32. Both sides of the sliding platform 32 are connected to the first guide rail 33 and the second guide rail 34. The material receiving assembly also includes a slider 35 that is slidably connected to the sliding platform 32. The slider 35 is slidably matched with the sliding platform 32, the first guide rail 33, and the second guide rail 34. A rotating rod 36 is rotatably connected to the slider 35, and one end of the rotating rod 36 is fixedly connected to the material receiving box 37. A fixed plate 38 is fixedly connected to the slider 35. Two guide grooves are symmetrically opened on the frame 1, and the two guide grooves are connected. The two rotating rods 36 are slidably connected in the guide grooves one by one.

[0029] The power source for the sliding of the moving frame 31 is: a screw rod 7 is rotatably connected to the frame 1, and the screw rod 7 is screwed to the moving frame 31; a driving source for driving the screw rod 7 to rotate is rotatably connected to the frame 1, specifically, the driving source is a motor, and the output end of the motor is coaxially fixedly connected to the screw rod 7, and the motor is used to drive the screw rod 7 to rotate forward and reverse, thereby driving the moving frame 31 to reciprocate on the frame 1.

[0030] Specifically, the first guide rail 33 is inclined at the upper right, and the second guide rail 34 is inclined at the upper left. When the slider 35 slides with the first guide rail 33 and the second guide rail 34, as shown in FIG. Figure 8 As shown, the slider 35 is slidably matched with the side walls of the first guide rail 33 and the second guide rail 34 through a plurality of side walls distributed along the axis of the rotating rod 36 except the sliding plane 351 .

[0031] Specifically, since the slider 35 is a cube rotated 45 degrees, the bottom of the slider 35 cannot slide in contact with the effective travel surface of the sliding platform 32 . Therefore, the bottom of the slider 35 has a sliding plane 351 , and the sliding plane 351 slides with the sliding platform 32 .

[0032] Specifically, each guide groove is composed of a horizontal section 11 , a corner section 12 , a vertical section 13 and a pouring section 14 . It is worth mentioning that the two guide grooves are connected to each other through the two horizontal sections 11 .

[0033] In an embodiment of the present invention, two rotating mechanisms 4 are also included, and the rotating mechanisms 4 are used to flip the material receiving box 37 so that the mouth of the material receiving box 37 faces downward, so that the ink received by the material receiving box 37 can fall down; specifically, the two rotating mechanisms 4 correspond to the two material receiving components one by one, and each rotating mechanism 4 includes a worm gear 41 fixedly connected to the rotating rod 36, a worm 42 is rotatably connected to the fixed plate 38, a gear 43 is fixedly connected to the worm 42, and a rack 44 is fixedly connected to the frame 1, and the gear 43 is meshed with the rack 44.

[0034] Preferably, it also includes a scraper mechanism 5, which is used to scrape off the ink attached to the inner wall of the material receiving box 37 during the process of unloading the material from the material receiving box 37; it includes a fixed seat 51 fixedly connected to the frame 1, a lifting seat 52 is vertically slidably connected to the fixed seat 51, a first spring 53 is arranged between the lifting seat 52 and the fixed seat 51, scrapers 54 are respectively slidably connected to the two sides of the lifting seat 52, second springs 55 are arranged between the two scrapers 54 and the lifting seat 52, and the two scrapers 54 are respectively and one by one correspondingly abutted against the two material receiving boxes 37.

[0035] Preferably, two limit mechanisms 6 are also included, and the function of the limit mechanisms 6 is that when the rotating rod 36 needs to slide from the horizontal section 11 into the corner section 12, the rotating rod 36 can be ensured to be located in the corner section 12 by moving the lever 63; at the same time, since the lever 63 is in a horizontal state in the initial state, when the rotating rod 36 slides from the corner section 12 into the horizontal section 11, it is not affected and can directly enter the horizontal section 11; specifically, the two limit mechanisms 6 correspond to the two material receiving components one by one, and each limit mechanism 6 includes a rotating shaft 61 fixedly connected to the frame 1, one end of the rotating shaft 61 is fixedly connected to the abutment rod 62, and the other end is fixedly connected to the lever 63, the abutment rod 62 abuts and cooperates with the moving frame 31, and the rotating shaft 61 abuts and cooperates with the rotating rod 36; specifically, a torsion spring is arranged between the rotating shaft 61 and the frame 1, and the torsion spring drives the rotating shaft 61 to reset after rotation.

[0036] When in use, in the initial state, such as Figure 7 As shown, the material receiving box 37 on the right side is located at the material discharge port 22 and is in a material receiving state. At this time, the movable frame 31 moves to the right on the frame 1. During the movement, the side wall of the first guide rail 33 of the movable frame 31 abuts against a rotating rod 36 on the left side, so it will drive the rotating rod 36 and the material receiving box 37 to slide to the right on the sliding plane 351 synchronously. In addition, during the sliding process, the material receiving box 37 will push away the other material receiving box 37 located below the material discharge port 22, and the sliding material receiving box 37 will be located below the material discharge port 22, so that the two material receiving boxes 37 are alternately located below the material discharge port 22, ensuring that during the material return process, there will always be a material receiving box 37 below the material discharge port 22 to receive the material.

[0037] During the movement of the moving frame 31, it will abut against the abutment rod 62, driving the rotating shaft 61 and the lever 63 to rotate around the axis of the rotating shaft 61. During the rotation, the lever 63 will push the pushed rotating rod 36, and through the pushing of the lever 63, the rotating rod 36 enters the corner section 12 from the horizontal section 11.

[0038] Subsequently, the movable frame 31 moves to the left on the frame 1, and through the cooperation between the first guide rail 33 and the slider 35, the slider 35 slides to the upper right along the first guide rail 33, and the rotating rod 36 enters the vertical section 13 from the corner section 12 and moves upward. Through the cooperation between the second guide rail 34 and the slider 35, the rotating rod 36 is driven from the vertical section 13 to enter the unloading section 14.

[0039] It should be noted that: during the process of the movable frame 31 moving to the left on the frame 1, the material receiving box 37 located below the discharge port 22 remains stationary and is always in the material receiving position. The reason is that: during the process of the movable frame 31 moving to the left, the slider 35 on the stationary material receiving box 37 slides on the sliding platform 32.

[0040] In the material unloading section 14, the gear 43 is meshed with the rack 44, and the worm wheel 41 and the worm 42 are meshed to drive the rotating rod 36 to rotate and flip during the lateral movement, so that the material receiving box 37 is flipped synchronously, so that the material receiving box 37 is rotated from the mouth facing upward to the mouth facing downward, and the material receiving box 37 abuts against the scraper 54 during the flipping, and due to the action of the abutting force, the scraper 54 is driven to shrink into the fixed seat 51, and with the force of the rotation of the material receiving box 37, the lifting seat 52 is driven to shrink and descend into the fixed seat 51, so that the scraper 54 always abuts against the inner wall of the material receiving box 37, while sliding from one end of the inner wall of the material receiving box 37 to the other end, scraping off the sticky ink left at the bottom of the material receiving box 37, and the grinding mechanism 2 is used to grind it again.

[0041] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
