Description

Technical Field

[0001] The invention belongs to the technical field of steel printing rollers, and in particular relates to a method for synchronously adjusting a steel printing roller and a knife disc and a rolling device. Background Art

[0002] The steel stamped brand of cigarettes is an intuitive identification of a brand and also a declaration of intellectual property rights, and the steel stamp roller that undertakes the printing task is a crucial workpiece. The steel stamp roller is a cylinder with a mounting hole in the center and a mold engraved on its outer cylindrical surface. The diameter of the steel stamp roller and the circumference of the top edge of the mold depend on the length of the cigarette produced. The steel stamp roller accurately prints the brand on the outer surface of the cigarette paper. When the rolled cigarette rods reach the cutter disc for cutting, the printed set of brand names must be evenly distributed on both sides of the cut and must not exceed the design value range. Therefore, it is very important to determine the printing zero position of the steel stamp roller, that is, the synchronization of the printing start phase of the steel stamp roller with the cutting position of the cutter of the cutter disc.

[0003] At present, the ZJ17 type winder uses two steel printing rollers. After replacement, it is impossible to determine the printing zero position of the two steel printing rollers, and it is even more difficult to determine the synchronization position of the two steel printing rollers and the cutter disc. The operator needs to adjust the installation phase of the two steel printing rollers multiple times based on experience, and it is also necessary to start the machine for verification multiple times, resulting in a time-consuming and labor-intensive process for determining the phase synchronization position of the steel printing roller and the cutter disc, and low efficiency. Therefore, how to design an adjustment method to make it easy to determine the synchronization position of the two steel printing rollers and the cutter disc and improve efficiency has become a technical problem that technicians in this field urgently need to solve. Summary of the invention

[0004] The purpose of the present invention is to provide a method for synchronously adjusting a steel printing roller and a knife disc to solve the above technical problems in the prior art. Another purpose of the present invention is to design a winding and splicing device.

[0005] To achieve the above object, the present invention provides the following technical solutions:

At this time, the first steel printing roller and the second steel printing roller are both synchronized with the phase of the knife disc.

[0010] Preferably, in step S1, the specific method for preparing the first steel stamp roller and the second steel stamp roller with the "0" position line mark is:

[0018] In the same way, mark the four characters on the second steel stamp roller as A1, B1, C1, and D1, of which A1 and C1 are collar end characters;

[0019] Step S1.4, marking the "0" position line on the first steel stamp roller and the second steel stamp roller.

[0020] Preferably, in step S1.4, the method for marking the "0" position line on the second steel printing roller is:

[0021] The length of the detour path of the cigarette paper between the cutting position of the cutter and the printing position of the second steel printing roller is measured and recorded as S;

[0022] Divide S by the length of the cigarette to get the quotient and remainder, where the remainder is denoted as r;

[0023] With the center of the second steel stamp roller as the center of the circle and the position on the end surface of the second steel stamp roller opposite to the center line of the character mold A1 as the starting point, rotate the arc length r in the running direction of the second steel stamp roller, and mark the scale line with a distance r from the starting point as the "0" position line;

[0045] In order to enable those skilled in the art to better understand the technical solution of the present invention, the solution will be further described in detail below in conjunction with specific embodiments.

[0046] like Figures 1 to 3 As shown, an embodiment of the present invention provides a method for synchronously adjusting a steel printing roller and a knife disc, which comprises the following steps:

[0047] Step S1, preparing a first steel stamp roller 16 and a second steel stamp roller 21 with a "0" position line mark;

[0048] Step S2, placing any cutting knife of the cutting disc at a cutting position;

[0049] Step S3, align the "0" position line of the first steel printing roller 16 with the center line of the first printing roller 17, and align the "0" position line of the second steel printing roller 21 with the center line of the second printing roller 22. At this time, the first steel printing roller and the second steel printing roller are synchronized with the phase of the knife disc.

[0050] The method for synchronously adjusting the steel stamp roller and the cutter disc provided in the embodiment of the present invention, when installing a new steel stamp roller, only needs to place any cutting knife of the cutter disc in the cutting position, and then align one of the two "0" position lines of the first steel stamp roller 16 and the second steel stamp roller 21 having a "0" position line, i.e., a printing phase zero position mark, with the center line of the corresponding printing roller, respectively, so as to ensure the phase synchronization of the installed first steel stamp roller and the second steel stamp roller with the cutter disc, and accurately determine the synchronous position of each steel stamp roller and the cutter disc, thereby making the process of determining the synchronous position between each steel stamp roller and the cutter disc relatively simple, and effectively improving the work efficiency.

[0051] Further, in step S1, the specific method for preparing the first steel stamp roller 16 and the second steel stamp roller 21 with the "0" position line mark is:

[0052] Step S1.1, determine the circumference and diameter of the first steel stamp roller and the second steel stamp roller:

[0053] The circumference of both is the required cigarette length × 4, and the diameter of both is the circumference divided by π;

[0054] Step S1.2, engraving scale lines:

[0055] A circle of scale lines is uniformly engraved on the circumference of the end surface of the first steel printing roller, and the spacing between two adjacent scale lines is 2 mm;

[0056] A circle of scale lines is also uniformly engraved on the circumference of the end surface of the second steel printing roller, and the spacing between two adjacent scale lines is 2mm;

[0057] Step S1.3, marking the collar end font:

[0058] Observe from the running direction of the first steel printing roller during printing, the two character molds with the head facing right among the four character molds 13 of the first steel printing roller 16 are both collar end character molds, and the two character molds are marked as A and C respectively, and the other two character molds are marked as B and D respectively, and the character molds are arranged in the clockwise direction as A, B, C, and D;

[0059] According to the same method, the four fonts on the second steel stamp roller are marked as A1, B1, C1, and D1, among which A1 and C1 are both collar-end fonts; specifically, according to the running direction of the second steel stamp roller during printing, the two fonts with the head facing right among the four fonts of the second steel stamp roller are both collar-end fonts, and these two fonts are marked as A1 and C1 respectively, and the remaining two fonts are marked as B1 and D1 respectively, and the fonts are arranged in the clockwise direction as A1, B1, C1, and D1;

[0060] Step S1.4, marking the "0" position line on the first steel stamp roller and the second steel stamp roller.

[0061] Specifically, in step S1.4, the method of marking the "0" position line on the second steel printing roller is:

[0062] The length of the detour path of the cigarette paper between the cutting position of the cutter and the printing position of the second steel printing roller is measured and recorded as S;

[0063] Divide S by the length of the cigarette to get the quotient and remainder, where the remainder is denoted as r;

[0064] With the center of the second steel stamp roller as the center of the circle and the position on the end surface of the second steel stamp roller opposite to the center line of the character mold A1 as the starting point, rotate the arc length r in the running direction of the second steel stamp roller, and mark the scale line with a distance r from the starting point as the "0" position line;

[0065] With the center of the second steel stamp roller as the center of the circle and the position on the end face of the second steel stamp roller opposite to the center line of the character mold C1 as the starting point, rotate an arc length r in the running direction of the second steel stamp roller, and mark the scale line with a distance r from the starting point as the "0" position line.

[0066] Preferably, when measuring S, any cutter on the knife disc is located at the cutting position, and any character mold on the second steel printing roller is located at the printing position. At this time, the length of the detour path of the cigarette paper between the cutting position and the printing position of the character mold of the second steel printing roller 21 is measured, thereby making the measurement of S more convenient.

[0067] Further, in step S1.4, the method of marking the "0" position line on the first steel printing roller is:

[0068] The length of the detour path of the cigarette paper between the first steel stamp roller and the second steel stamp roller is measured and recorded as S1;

[0069] Calculate the difference between the cigarette length and the color spacing, and divide S1 by the difference to get the quotient and remainder, which is recorded as r1;

[0070] With the center of the first steel printing roller as the center of the circle and the position on the end surface 12 of the first steel printing roller opposite to the center line of the character mold A as the starting point 14, the arc length r1 is rotated in the running direction of the first steel printing roller, and the scale line with a distance of r1 from the starting point is marked as the "0" position line;

[0071] With the center of the first steel stamp roller as the center of the circle and the position on the end face 12 of the first steel stamp roller opposite to the center line of the character mold C as the starting point 14, rotate the arc length r1 in the running direction of the first steel stamp roller, and mark the scale line with a distance r1 from the starting point as the "0" position line.

[0072] It can be understood that when measuring S1, any of the characters of the first steel printing roller 16 is in the printing position, and any of the characters of the second steel printing roller is in the printing position; at this time, S1 is measured without measuring the length of the cigarette paper detour path between the cutting position of the cutter and the printing position of the first steel printing roller, which can better avoid the error caused by the excessive length of the cigarette paper detour path, thereby making the engraving error of the "0" position line on the first steel printing roller smaller. The character mold is in the printing position, that is, the center line of the character mold is relatively straight with the center line of the printing roller.

[0073] The steel stamp rollers of domestic ZJ17 cigarette-making units are all steel cylindrical steel stamp rollers, with two pairs of four fonts 13 engraved on the outer circumference 11 (four cigarettes can be printed in one cycle), and the font parameters are designed for independent brands. The diameter and circumference of the steel stamp roller (the length of four cigarettes) are made according to the specifications of the length of the cigarettes produced. The knife disc of the ZJ17 cigarette-making unit is double-knife double-cut (that is, the knife disc can cut two double-length cigarettes in one cycle), and the position of the steel stamp printed on the double-length cigarette after cutting must meet the national standard requirements (steel stamp position: design value ± 2mm), that is, the steel stamp roller and the knife disc cutter have a synchronous operation phase, which requires adjusting the circumferential installation position of the steel stamp roller to achieve; no matter what specification and length of cigarettes are produced, the circumferential fixed installation position of the steel stamp roller can be obtained by calculating the relevant parameters.

[0074] In a specific embodiment, a ZJ17 cigarette making machine producing 59mm cigarettes is used as an example for explanation, and the length of the cigarette is 59mm; double-roller color printing, the steel printing roller diameter D = 75.16mm, the circumference C = 236mm, and two pairs of 4 character molds are distributed on its outer circumference;

[0075] First, a circle of scale lines is uniformly engraved on the circumference of the end faces of the first and second steel stamp rollers with a graduation value of 2 mm (the national standard GB5606 requires the steel stamp mark position to be the design value ± 2 mm). Then, 360° / C = 360° / 236 ≈ 1.5 / 1, that is, a central angle of 1.5 degrees corresponds to an arc length of 1 mm.

[0076] Then confirm and mark the collar end font, specifically: observe according to the running direction of the first steel printing roller and the second steel printing roller during printing, the two fonts with the head facing right among the four fonts are both collar end fonts, mark the two fonts with the head facing right on the second steel printing roller as A and C respectively, mark the other two fonts as B and D respectively, and arrange the fonts in the clockwise order as A, B, C, D, mark the two fonts with the head facing right on the first steel printing roller as A1 and C1 respectively, mark the other two fonts as B1 and D1 respectively, and arrange the fonts in the clockwise order as A1, B1, C1, D1; such marking is mainly to allow the operator to distinguish the positional relationship of each font printed on the cigarette strip, avoid the inversion of the printed mark, and be more conducive to the precise control of the printed mark;

[0077] Then, the "0" position line is marked, that is, the positioning mark of the zero position of the printing phase of the steel stamp roller, specifically: taking the second steel stamp roller of a certain brand as an example, S is measured to be 2064mm; the color spacing (that is, the spacing between the two steel stamps printed on the cigarette paper) is 20mm; therefore, 2064÷59=34.98, that is, the quotient=34, r=98, and the quotient can be recorded as n at this time; taking the center of the second steel stamp roller as the center of the circle, and taking the position on the end face of the second steel stamp roller relative to the center line of the mold A1 and the mold C1 as the starting point, after rotating in the running direction of the steel stamp roller by an arc length of r, the corresponding scale line is marked as the "0" position line, that is, the scale line with a spacing of r from the starting point is marked as the "0" position line; the "0" position line is also the zero position of the printing phase of the second steel stamp roller;

[0078] Then the "0" position line of the first steel stamp roller is marked, specifically: measure the length of the cigarette paper bypass path between the first steel stamp roller and the second steel stamp roller, recorded as S1, calculate the difference between the cigarette length and the color spacing, divide S1 by the difference to obtain the quotient n1, and the remainder r1; measure S1 = 152mm, S1 ÷ (cigarette length - color spacing) = 152 ÷ (59-20) = 3.90, that is, n1 = 3, r1 = 90; take the center of the first steel stamp roller as the center of the circle, and take the position on the end face of the first steel stamp roller opposite to the center line of the mold A and the mold C as the starting point, and rotate in the running direction of the first steel stamp roller by an arc length of r1, and the corresponding scale line is marked as the "0" position line, that is, the scale line with a spacing of r1 from the starting point is marked as the "0" position line.

[0079] It can be understood that the above-mentioned character mold with the head facing right, that is, the head of the character mold 15 faces right, in actual production, after the printing is completed using this character mold, the head of the character printed on the cigarette paper faces upward; the distance from the printing position of the second steel printing roller to the cutting position of the cutter of the cutter disc can be regarded as a series of connected cigarettes (cigarettes of any length specification), but it is not necessarily an integer multiple, and its integer multiple part, that is, the quotient n, is the number of cigarettes, and the remainder r is the adjustment parameter when the phase synchronization is adjusted. Using the above scheme, after the synchronization phase of the first steel printing roller, the second steel printing roller and the cutter disc is determined, the rolling machine can directly produce products that meet the national standard requirements for printing positions.

[0080] The present invention further provides a roll-to-roll device, which comprises the first steel printing roller and the second steel printing roller described in any one of the above technical solutions. The roll-to-roll device of the present invention also has the above technical effects.

[0081] The present invention can accurately locate the synchronization of the printing phase of the first and second steel stamp rollers with the cutting phase of the knife disc at one time by engraving scale lines and a "0" position line on the first and second steel stamp rollers, thereby simplifying the startup adjustment method and steps after each replacement of the steel stamp rollers, avoiding the waste caused by repeated startup verification, and facilitating the improvement of printing quality.

[0082] The above are only preferred embodiments of the present invention. It should be pointed out that these embodiments are only used to illustrate the present invention and are not used to limit the scope of the present invention. Moreover, after reading the contents of the present invention, relevant technical personnel in the field may make various changes or modifications to the present invention, and these equivalent forms also fall within the scope defined by the claims attached to this application.
