Description

Technical Field

[0001] The present invention relates to the technical field of cigarette packaging equipment, and particularly relates to an adjusting tooling and an adjusting method for the scoring knife of the inner frame paper in a cigarette packaging machine. Background Art

[0002] The inner frame paper is a component used to support the box cover in a small box cigarette pack. In the cigarette packaging process, two parallel dotted lines and a U-shaped line need to be pressed on the inner frame paper. The cigarette packaging process has very high requirements for the position accuracy of the dotted lines and the U-shaped line on the inner frame paper. Slight improper adjustment will lead to product quality problems such as the inner frame paper flying out and the inner frame paper being torn. In severe cases, it will also affect the production efficiency of the equipment. In actual production, the dotted lines and the U-shaped line on the inner frame paper are processed by rolling with two parallelly installed scoring knives and corresponding rollers. The installation position accuracy of the two scoring knives directly affects the positions of the dotted lines and the U-shaped line on the inner frame paper. Therefore, the installation and adjustment accuracy of the scoring knife is crucial for ensuring the quality of the cigarette pack. In addition, incorrect adjustment of the scoring knife will also reduce the service life of the knife. At present, the installation and adjustment of the scoring knife in a cigarette packaging machine are mainly completed manually by visual inspection and experience. This adjustment method has low accuracy, low efficiency, and long time consumption. Especially when a failure occurs during the production process, readjusting the scoring knife using the empirical method seriously delays the production progress and reduces the production efficiency. Summary of the Invention

[0042] Please refer to Figures 1 to 3 , a preferred embodiment of the present invention provides an inner frame paper scoring knife adjustment tooling for a cigarette packaging machine, which includes a machine base 1, a sliding seat 9, a locking knob 6, a limiting block 15, a scale 8, and a centering scale 5.

[0043] The machine base 1 is generally in an inverted L shape. The machine base 1 includes a substrate 21 in an inverted L shape. The substrate 21 has a horizontal plate and a vertical plate that are perpendicular to each other. The horizontal plate is located above. The inner surface of the inverted L-shaped substrate 21 is L-shaped, which is used to achieve the rapid positioning of the tooling. A groove 22 is formed at the top of the horizontal plate of the substrate 21. The groove 22 is a rectangular groove, and a flat key 2 is arranged in the groove 22. The flat key 2 is arranged horizontally. A cover plate 3 covering the groove 22 is arranged on the top surface of the horizontal plate of the substrate 21. In an exemplary embodiment, the flat key 2 is fixedly arranged on the cover plate 3, and the cover plate 3 is fixedly installed on the substrate 21 through cover plate screws 4 to cover the groove 22.

[0044] In a preferred embodiment, a positioning piece 24 for positioning with the mounting support for supporting the scoring knife is arranged on the machine base 1. The positioning piece 24 can be arranged on the side surface of the horizontal plate or the side surface of the vertical plate of the substrate 21 according to specific needs, or positioning pieces 24 are arranged on both, or it is shared by the horizontal plate and the vertical plate. By arranging the positioning piece 24, it can be ensured that the position of the machine base 1 and the mounting support for supporting the scoring knife is relatively fixed in the horizontal direction. At this time, the machine base 1 can only move in the direction close to or away from the scoring knife.

[0045] The centering scale 5 is fixedly installed in the middle of the upper surface of the cover plate 3 and is arranged horizontally. The 0 scale line of the centering scale 5 is located in the middle, and the scales on the left and right sides are symmetrically distributed. Each small grid scale is 1 mm. The centering scale 5 is used to accurately display and adjust the position of the limiting block 15.

[0046] The slide 9 is mounted on the base 1 and can slide horizontally left and right on the base 1. The slide 9 is provided with a center scale line 16 in the middle of the position near the centering scale 5, and the slide 9 is provided with a horizontally arranged wedge block 17 on the side away from the base 1. The slide 9 is provided with a horizontally arranged keyway 23, and the slide 9 is partially located in the groove 22 and is sleeved on the flat key 2 through the keyway 23 so that the slide 9 can slide horizontally on the base 1. Specifically, in an exemplary embodiment, one side of the slide 9 is a flat plate 13 and the other side is a wedge block 17, a boss 14 is provided between the wedge block 17 and the flat plate 13, a center scale line 16 is provided at the center of the upper surface of the boss 14, a keyway 23 is provided on the flat plate 13, the flat plate 13 is located in the groove 22, and its thickness is consistent with the depth of the groove 22, the longitudinal width of the flat plate 13 is the same as the width of the groove 22 at the top of the support 1, and the lateral length of the flat plate 13 is 2 / 3 of the length of the groove 22; the flat key 2 on the cover plate 3 and the flat plate 13 of the slide 9 can slide relative to each other through the keyway, and when the support 1 is fixed, the slide 9 can be moved to make the slide 9 slide horizontally in a straight line on the support 1.

[0047] The cover plate 3 is provided with a threaded hole, and the locking knob 6 is screwed into the threaded hole of the cover plate 3 and can support the flat plate 13 of the slide seat 9, so that the slide seat 9 can be fixed at a certain position of the slide seat 9.

[0048] One end of the limit block 15 is V-shaped to form a V-shaped limit block, which is a pentagonal flat plate structure with a side projection. One end of the limit block 15 is provided with a dovetail groove 18 matching the wedge block 17 so that the limit block 15 can be installed on the wedge block 17 through the dovetail groove 18 and can slide horizontally on the wedge block 17. At this time, the two limit blocks 15 can slide relative to the slide 9. The limit block 15 is provided with a threaded hole at the end of the wedge block 17, and the limit block 15 and the slide 9 can be fixed by a first screw 10, which is used to fix the limit block 15 at a certain position of the wedge block 17, that is, fixed at a certain position of the slide 9. The other end of the limit block is also provided with a threaded hole, which is connected to the scale 8 by a second screw 7.

[0049] A longitudinally extending V-shaped groove 19 is provided in the center of the bottom surface of the limit block 15. The V-shaped groove 19 is used to interact with the notching knife. When adjusting the notching knife, the tip of the notching knife needs to be directly opposite to the V-shaped groove 19 and embedded in the V-shaped groove 19. At this time, the V-shaped groove 19 can play a limiting role for the notching knife. The notch angle of the V-shaped groove 19 is smaller than the tip angle of the notching knife. When the V-shaped groove 19 contacts the notching knife, the blade of the notching knife tip must be suspended in the air and not in contact with the V-shaped groove 19 to avoid damaging the notching knife. The material of the limit block 15 is copper to prevent hard metal from contacting the notching knife blade and damaging the notching roller and the notching knife thereon.

[0050] One end of the scale 8 is fixed on one of the limit blocks 15, and a long slot 20 is provided at the other end. A second screw 7 passing through the long slot 20 is provided on the other limit block 15. Each small scale of the scale 8 is 1 mm. In a preferred embodiment, the top surface of the other end of the limit block 15 away from the wedge block 17 is provided with an inclined surface. The scale 8 is arranged on the inclined surface at the end of the limit block 15. Threaded holes are respectively provided on the inclined surfaces of the two limit blocks 15. A round hole is provided at one end of the scale 8, and a long slot 20 is provided at the other end. There are two second screws 7. One passes through the round hole and is screwed into the threaded hole of the limit block 15, and the other passes through the long slot 20 and is screwed into the threaded hole of the limit block 15. At this time, the scale 8 is relatively fixed to the limit block 15; when the second screw 7 is loosened, such as when the second screw 7 corresponding to the long slot 20 is loosened, the scale 8 can move relative to the limit block 15. Then when the scale 8 is fixed relative to one limit block 15, the limit block 15 corresponding to the long slot 20 can move relative to the scale 8 to adjust the distance between the two limit blocks 15, that is, to adjust the distance between the V-shaped grooves 19 of the two limit blocks 15. Since the inner frame paper size specifications of different brands of cigarettes are different, the positions of the two limit blocks 15 can be adjusted to meet the adjustment of inner frame papers of different size specifications.

[0051] In a preferred embodiment, to ensure that the limit block 15 and the sliding seat 9 can slide easily, lubricating oil is applied to the groove wall of the keyway 23 and the side wall of the wedge block 17 for lubrication.

[0052] A preferred embodiment of the present invention also provides a method for adjusting the scoring knife of the inner frame paper of a cigarette packaging machine. Please refer to Figure 4 and Figure 5 , and this method uses the above-mentioned adjusting tool for the scoring knife of the inner frame paper of a cigarette packaging machine, and includes the following steps:

[0053] S1. Query or measure the distance between the two dotted lines of the inner frame paper, and loosen the first screw 10 and the second screw 7 on the limit block 15 acting on the long slot 20 so that the distance (center distance) between the V-shaped grooves 19 of the two limit blocks 15 is equal to the distance between the two dotted lines of the inner frame paper.

[0054] In the method of the present invention, the distance between the two limit blocks 15 and the distance between the V-shaped grooves 19 can be quickly read through the scale 8. In a preferred embodiment, for one end of the scale 8 without the long slot 20, the corresponding limit block 15 does not need to be adjusted, and when the other limit block 15 is at the nearest position away from this limit block 15 (limited by the long slot 20), the two limit blocks 15 are symmetric with respect to the 0 scale line of the centering scale 5. Then when adjusting the relative distance between the two limit blocks 15, only the limit block 15 acting on the long slot 20 needs to be adjusted.

[0055] S2. Tighten the first screw 10 and the second screw 7 on the limit block 15 that acts on the long slot 20. At this time, the two limit blocks 15 are relatively fixed.

[0056] S3. Loosen the locking knob 6, and move the sliding seat 9 so that the two limit blocks 15 are symmetric with respect to the 0 scale line on the centering scale 5. Then tighten the locking knob 6 to make the sliding seat 9 and the machine base 1 relatively fixed.

[0057] Exemplarily, taking the scale line of the scale 8 aligned with the second screw 7 on the long slot 20 when it is at the leftmost end of the long slot 20 as a reference, if the position of the second screw 7 on the long slot 20 is 1 scale to the right, adjust the sliding seat 9 so that the center scale line 16 on the boss 14 of the sliding seat 9 aligns with the centering scale 5 at 1 / 2 scale to the left. If it is 2 scales to the right, adjust the sliding seat 9 so that the center scale line 16 on the boss 14 of the sliding seat 9 aligns with the centering scale 5 at 1 scale to the left, and so on. At this time, it can be ensured that the two limit blocks 15 are symmetric with respect to the 0 scale line on the centering scale 5.

[0058] S4. Loosen the locking screw of the scoring knife 25, bring the adjustment tooling close to the mounting seat 26 on the equipment that supports the scoring knife 25, make the surface of the support 1 of the adjustment tooling fit with the surface of the mounting seat 26, ensure that the side surface of the machine base 1 is aligned with the end surface of the mounting seat 26, and at this time, the symmetry axis of the two limit blocks 15 is consistent with the symmetry axis of the two scoring knives 25 after adjustment.

[0059] During implementation, the inner surface of the L-shaped base plate 21 of the machine base 1 is aligned with the end surface of the mounting seat 26. At this time, the symmetry axis of the two limit blocks 15 is consistent with the symmetry axis of the two scoring knives 25 after adjustment, taking this as a reference. And when there is a positioning piece 24 on the machine base 1, it can ensure that the positions of the machine base 1 and the mounting seat 26 supporting the scoring knife 25 are relatively fixed in the horizontal direction. At this time, the machine base 1 can only move in the direction of approaching or moving away from the scoring knife 25, and cannot move horizontally left and right.

[0060] S5. Move and adjust the two scoring knives 25 so that the two scoring knives 25 are respectively facing the V-shaped grooves 19 of the two limit blocks 15. Then move the machine base 1 towards the scoring knives 25 so that the two scoring knives 25 are respectively embedded in the two V-shaped grooves 19. At this time, the positions of the two scoring knives 25 are adjusted accurately.

[0061] S6. Tighten the locking screws on the scoring knives. At this time, the scoring knife 25 is adjusted in place, and the adjustment of the scoring knife 25 is completed.

[0062] The following is a more specific and exemplary method for adjusting the scoring knife of the inner frame paper of a cigarette packaging machine. It is measured that the distance between two dotted lines of the inner frame paper is 54 mm, the length of the wedge block 17 of the slide 9 is 70 mm, and when the second screw 7 in the long slot 20 is at the extreme left position of the long slot 20, the center line of the screw aligns with the scale 5 of the scale 8.

[0063] Loosen the first screw 10 and the second screw 7 on the limit block 15 connected to the long slot 20, and adjust the position of the limit block 15 so that the distance between the V-shaped grooves 19 of the two limit blocks 115 is equal to 54 mm.

[0064] Tighten the first screw 10 and the second screw 7 on the limit block 15 connected to the long slot 20.

[0065] Loosen the locking knob 6, move the slide 9, and align the center scale line 16 on the boss 14 of the slide 9 with the scale line 2 grids to the left of the centering scale 5. At this time, the two limit blocks 15 are symmetric with respect to the 0 scale line on the centering scale 5.

[0066] Loosen the locking screw of the scoring knife, gently bring the adjustment tooling close to the mounting seat on the equipment used to support the scoring knife, make the L-shaped inner surface of the tooling seat 1 fit with the two surfaces of the mounting seat, and at the same time ensure that the side surface of the work is aligned with the end surface of the mounting seat.

[0067] Move and adjust the two scoring knives 25 so that the two scoring knives 25 are respectively facing the V-shaped grooves 19 of the two limit blocks 15, and then move the machine base 1 towards the scoring knives 25 so that the two scoring knives 25 are respectively embedded in the two V-shaped grooves 19. At this time, the positions of the two scoring knives 25 are accurately adjusted.

[0068] Tighten the locking screw on the scoring knife, and the adjustment of the scoring knife is completed.

[0069] The method for adjusting the scoring knife of the inner frame paper of the cigarette packaging machine of the present invention, using the adjustment tooling for the scoring knife of the inner frame paper of the cigarette packaging machine of the present invention, can realize the adjustment of the scoring knife with high accuracy, high speed and high versatility.

[0070] The above is only the specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by those skilled in the art within the technical scope disclosed by the present invention should be covered by the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope of the claims.
