Description

Technical Field

[0001] The invention relates to the technical field of hard box packaging machines, and in particular to a positioning tool for a crease cutter assembly. Background Art

[0002] After the step of inputting the inner frame paper, the crease cutter assembly performs dotted line cutting and "U"-shaped cutting on the inner frame paper of the hard box packaging machine. The crease cutter assembly consists of double gears, lining rollers, transmission shafts and a pair of crease cutters. The crease cutters include dotted line cutters and U-shaped cutters. The crease cutter assembly is installed on the machine wall by bolts. When working, the lining roller and the crease cutter rotate in opposite directions with the rotation of the gears, and crease and cut the inner frame paper tape passing by.

[0003] The cutter distance between the two dotted line cutters is X, the cutter centerline of X is MN, and the fixed distance of MN from the machine wall is Y. X is determined according to the width of the cigarette pack, and is usually 1mm smaller than the width of the cigarette pack. In production, if the position of the above-mentioned cutter distance X or the cutter centerline MN is incorrect during adjustment, it will cause the inner frame paper cutting to not meet the requirements, the appearance quality of the cigarette pack will be defective, the inner frame paper will be missing, damaged or wrinkled, the cigarette pack cover will not be tight, and the bevel of the cigarette pack will be missing. At present, the vernier caliper on-site measurement method is used to adjust the axial positioning of the crease cutter assembly. The vernier caliper cannot be aligned with the blade, and the distance between the two dotted line cutters cannot be directly measured. Only another measuring surface can be selected. The axial movement of the crease cutter mounting flange seat is usually measured to calculate the X value. Due to the limitation of the spatial structure, the measurement is difficult and it is not easy to ensure the measurement accuracy. Repeated measurement, calculation and adjustment are required to meet the requirements, which is time-consuming and seriously affects work efficiency.

[0004] Therefore, how to provide a positioning tool for a crease cutter assembly that simplifies the measurement process, ensures measurement accuracy, and improves work efficiency is a technical problem that technical personnel in this field urgently need to solve. Summary of the invention

DETAILED DESCRIPTION

[0027] 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.

[0028] In order to enable those skilled in the art to better understand the scheme of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0029] Please refer to Figures 1 to 7 ,in, Figure 1 A schematic diagram of the structure of a positioning tool for a crease cutter assembly provided in an embodiment of the present invention, Figure 2 for Figure 1 AA schematic diagram, Figure 3 Schematic diagram of the installation dimensions of the crease cutter assembly in the prior art. Figure 4 Schematic diagram of the size adjustment of the crease cutter assembly in the prior art. Figure 5 It is a schematic diagram of the disassembly of the crease cutter assembly in the prior art. Figure 6 A schematic diagram of the application of a positioning tool for a crease cutter assembly provided in an embodiment of the present invention, Figure 7 The present invention is a flow chart of a method for on-site measurement using a vernier caliper in the prior art.

[0030] like Figure 3 As shown, the crease cutter assembly is composed of a double gear, a lining roller, a transmission shaft 17 and a pair of crease cutters. The crease cutter assembly is installed on the machine wall through bolts 20, the lining roller is installed on the upper bracket 15, and the crease cutter is installed on the lower bracket 16. Each crease cutter includes a dotted line cutter and a U-shaped cutter which are circular knives. When working, the lining roller and the crease cutter rotate in opposite directions with the rotation of the gear, and crease and cut the inner frame paper tape passing through. The two crease lines in the middle of the inner frame paper tape that has been creased are composed of an alternating combination of dotted line cutting and U-shaped cutting, which is convenient for folding along this point during subsequent packaging.

[0031] The value X is the distance between the cutting edges of the two dotted line cutters mounted on the same transmission shaft 17. X has been specified in the packaging specifications and is determined based on the width of the cigarette pack. It is usually 1 mm smaller than the width of the cigarette pack. The center line of the cutter of X is MN, and the fixed distance of MN from the machine wall is Y. The value Y is the distance between the center line of the crease cutter assembly and the positioning surface of the lower bracket 16.

[0032] In the actual adjustment process, the X value is difficult to measure, and it is even more difficult to ensure that the center line of the crease cutter assembly coincides with the straight line MN, resulting in a large adjustment error. It takes multiple measurements and adjustments to meet the requirements, which is time-consuming. In order to overcome the above defects, the present invention provides a positioning tool for a crease cutter assembly.

[0033] In a first specific embodiment, the positioning tool for the crease cutter assembly provided by the present invention includes a base plate 4, and the base plate 4 is provided with a first positioning plate 2 and a second positioning plate 3 as a tooling plane. The first positioning plate 2 and the second positioning plate 3 correspond to the first crease cutter 19 and the second crease cutter 18 of the crease cutter assembly respectively. The first positioning plate 2 positions the first crease cutter 19, and the second positioning plate 3 positions the second crease cutter 18. A pair of crease cutters of the crease cutter assembly are positioned under the action of the above-mentioned positioning plates, thereby realizing the positioning adjustment of the crease cutter assembly. There is no need to measure the cutting distance, which solves the problem of being unable to measure and inaccurately adjusting. The tooling can be used to adjust to the required cutting distance at one time, which solves the problems of repeated adjustment, long time consumption and low efficiency.

[0034] In this embodiment, the positioning tool for the crease cutter assembly is particularly suitable for the YB45 hard box packaging machine. When in use, the cutting distance between the first crease cutter 19 and the second crease cutter 18 that need to be positioned and adjusted is first determined, that is, the above-mentioned X value is first determined; then the required cutting distance is adjusted using the first positioning plate 2 and the second positioning plate 3, that is, the distance X between the first positioning plate 2 and the second positioning plate 3 is determined again; finally, the first crease cutter 19 is moved and adjusted to be positioned on the first positioning plate 2, and the second crease cutter 18 is the same, that is, the distance X between the first crease cutter 19 and the second crease cutter 18 is finally determined to complete the positioning adjustment.

[0035] Among them, a positioning tool with different cutting knife distances can be set according to different X values; illustratively, the distance between the first positioning plate 2 and the second positioning plate 3 can also be set to an adjustable state. At this time, the positioning tool can realize the setting of multiple X values, and the applicable scenarios are more extensive.

[0036] It should be noted that there are multiple adjustable settings, such as detachable adjustable and non-detachable adjustable.

[0037] In the detachable adjustable configuration, the base plate 4 has a plurality of positions for the above-mentioned positioning plate to be detachably connected, and threaded connection or the like can be adopted. By installing the above-mentioned positioning plate at a specific position of the base plate 4 to adapt to the setting of the first X value, the positioning plate can be removed and installed at another specific position of the base plate 4 to adapt to the setting of the second X value, and so on.

[0038] In the non-disassembly adjustable type, the difference from the disassembly adjustable type is that there is no need to repeatedly disassemble and assemble the positioning plate. It is only necessary to move the positioning plate on the bottom plate 4 and adjust the various spacings of the positioning plate to adapt to the settings of various X values.

[0039] Exemplarily, the positioning plate is slidably connected to the bottom plate 4. In the process of adjusting the X value, it is only necessary to move the positioning plate on the bottom plate 4 to change the spacing without disassembly, which is simple and quick.

[0040] In addition, it also includes an adjustment plate 1 arranged on the bottom plate 4, and the side of the adjustment plate 1 is an inclined surface that contacts the first positioning plate 2 and / or the second positioning plate 3, so as to adjust the first positioning plate 2 and the second positioning plate 3 when pushing the adjustment plate 1. The function of the adjustment plate 1 is to adjust the first positioning plate 2 or the second positioning plate 3 separately to change the spacing and adapt to the X value, or to adjust the first positioning plate 2 and the second positioning plate 3 at the same time to change the spacing and adapt to the X value. During the adjustment process, the function of the inclined surface is to transform and transmit the force of the adjustment plate 1 to the above-mentioned positioning plates to achieve a change in the direction of the force.

[0041] In a specific embodiment, the adjustment plate 1, the first positioning plate 2 and the second positioning plate 3 are all slidably connected to the bottom plate 4. The setting mode of the sliding connection includes but is not limited to the slide rail type, and other existing means for realizing the sliding connection should fall within the description scope of this embodiment.

[0042] Exemplarily, a sliding connection form in which a guide rail and a guide groove cooperate is adopted. Among them, the bottom plate 4 is provided with a guide rail, and there are three types of guide rails according to different uses and positions, corresponding to the adjustment plate 1, the first positioning plate 2 and the second positioning plate 3, respectively, and the adjustment plate 1, the first positioning plate 2 and the second positioning plate 3 are provided with guide grooves slidably connected to the guide rails, and there are three types of guide grooves corresponding to the above three types of guide rails.

[0043] In this embodiment, the adjustment plate 1 is slidably arranged in the vertical direction, and the first positioning plate 2 and the second positioning plate 3 are slidably arranged in the horizontal direction perpendicular to the vertical direction. The adjustment plate 1 is arranged between the first positioning plate 2 and the second positioning plate 3, so that when the adjustment plate 1 is pushed, the cross-sectional width of the contact position between the adjustment plate 1 and the first positioning plate 2 and the second positioning plate 3 gradually expands with the inclination of the inclined surface, and then under the action of the inclined surface, the first positioning plate 2 and the second positioning plate 3 are pushed to both sides horizontally to change the spacing.

[0044] More specifically, the adjustment plate 1, the first positioning plate 2 and the second positioning plate 3 are provided with strip holes, which are arranged in the same direction as the sliding direction. The strip holes are provided with positioning handle screws and washers 14, and the adjustment plate 1, the first positioning plate 2 and the second positioning plate 3 adjusted along the strip holes are locked on the base plate 4 through the handle screws and washers 14.

[0045] Among them, the strip hole of the adjustment plate 1 is arranged in the vertical direction and the adjustment handle screw 11 is passed through to lock the adjustment plate 1 after it is moved; the strip hole of the first positioning plate 2 is arranged in the horizontal direction and the first positioning handle screw 10 is passed through to lock the first positioning plate 2 after it is moved; the strip hole of the second positioning plate 3 is arranged in the horizontal direction and the second positioning handle screw 12 is passed through to lock the second positioning plate 3 after it is moved.

[0046] In addition, the base plate 4 is provided with a positioning end 13, which extends out at the left end. The left end surface of the extended part of the positioning end 13 is the positioning surface when the positioning tool is used. The positioning end 13 contacts and is positioned on the machine wall in a vertical form to install and position the positioning tool, thereby satisfying the adjustment of the cutter center line.

[0047] In this embodiment, the positioning end 13 of the bottom plate 4 is positioned on the machine wall of the lower bracket 16, and the machine wall of the lower bracket 16 is a finely processed wall ( Figure 5 The distance between the finishing wall and MN is the above-mentioned Y value, and Y is a fixed value. Even if the product specifications are changed or the components are disassembled and assembled, the Y value remains unchanged. Therefore, the positioning tool can be installed and positioned based on the machine wall.

[0048] In a specific embodiment, the shape of the adjustment plate 1 is an isosceles trapezoid, and the adjustment plate 1 is symmetrically arranged with the cutter center line as the axis. At this time, the distance between the center line of the guide rail arranged on the bottom plate 4 corresponding to the adjustment plate 1 and the positioning surface of the positioning end 13 is the above-mentioned Y value.

[0049] In this embodiment, the first positioning plate 2 and the second positioning plate 3 are both right-angled trapezoids, the hypotenuses of the two right-angled trapezoids have the same inclination as the two hypotenuses of the isosceles trapezoid, and are configured in reverse. The first positioning plate 2 and the second positioning plate 3 are symmetrically arranged on the left and right sides of the adjustment plate 1.

[0050] In a specific implementation, it includes an adjusting screw 5 disposed on the bottom plate 4 , the adjusting screw 5 is threadedly connected to the adjusting plate 1 , and the adjusting screw 5 can rotate to push the adjusting plate 1 .

[0051] Among them, the adjusting screw 5 is installed on the mounting seat, and the mounting seat includes a first mounting seat 6 arranged on the base plate 4 and a second mounting seat 7 arranged on the adjustment plate 1. The adjusting screw 5 is clearance-fitted in the first mounting seat 6, and the adjusting screw 5 is threadedly connected to the second mounting seat 7, so that when the adjusting screw 5 is rotated, the adjustment plate 1 can move along the guide rail on the base plate 4, and the first positioning plate 2 and the second positioning plate 3 move symmetrically left and right, and the center line remains unchanged.

[0052] More specifically, the first mounting seat 6 includes a pair of lugs, and a positioning ring 9 is arranged between the pair of lugs. The positioning ring 9 is fastened by a set screw 8, which can fasten and limit the axial movement of the adjustment screw 5; the second mounting seat 7 includes a lug with a threaded hole, and the adjustment screw 5 is threadedly connected in the threaded hole.

[0053] In this embodiment, the first positioning plate 2 and the second positioning plate 3 are provided with notches for matching with the cutting edges of the first crease cutter 19 and the second crease cutter 18. The notches are V-shaped and are provided with round holes at the bottom of the V. The round holes are Φ1 mm round holes, and their function is to prevent the cutting edges, i.e., the dotted disc cutter cutting edges, from being damaged when the positioning tool is used.

[0054] Taking the specification of X value of 54 mm as an example, there are scale lines with designed spacing on the right side of the upper plane of the first positioning plate 2 on the left, and three indications of 53, 54, and 55 are marked. A marking line is designed on the left side of the upper plane of the adjustment plate 1. The X value can be adjusted by rotating the adjustment screw 5. During adjustment, the first positioning plate 2 and the second positioning plate 3 move and the marking line corresponds to the scale line in real time. The design accuracy of the positioning tooling is 0.1 mm, and the adjustment range is X value 53~55 mm.

[0055] In addition, by changing the indicated value and the processing position of the V-shaped notch, the X value can be further changed according to the specifications of the cigarette products (ie, the width of the cigarette pack) to adapt to products of multiple specifications.

[0056] In this embodiment, by rotating the adjustment screw 5, the adjustment plate 1 can move along the guide rail on the bottom plate 4, and the adjustment plate 1 pushes the first positioning plate 2 and the second positioning plate 3 to move symmetrically left and right. During this process, the center line remains unchanged. The distance between the two V-shaped notches can be accurately positioned by adjusting the marking line on the plate 1 and the scale line on the first positioning plate 2, and then loosen the first locking screw 22 of the first crease cutter 19 and the second locking screw 21 of the second crease cutter 18, and move the first crease cutter 19 and the second crease cutter 18 left and right so that the cutting edges enter the two V-shaped notches respectively, and finally tighten the first locking screw 22 and the second locking screw 21. Remove the positioning tool, and the adjustment is completed.

[0057] Before using the positioning tool, the required X value size is first determined, and then the positioning adjustment is performed. There is no need to measure the distance between the two dotted disc blades, which solves the problem of being unable to measure; solves the problem of inaccurate adjustment; the positioning tool can be used to adjust to the required X value size at one time, which solves the problems of repeated adjustment, long time consumption and low efficiency.

[0058] It should be noted that, in this specification, relational terms such as first and second are merely used to distinguish one entity from other entities, but do not necessarily require or imply any actual relationship or order between these entities.

[0059] The above is a detailed introduction to the positioning tool for the crease cutter assembly provided by the present invention. Specific examples are used in this article to illustrate the principles and implementation methods of the present invention. The description of the above embodiments is only used to help understand the method of the present invention and its core idea.
