Description

Technical Field

[0001] This application relates to the field of tobacco packaging, and more particularly to a precision adjustment tooling for paper jam cutting in a ZB45 packaging machine. Background Technology

[0002] In tobacco packaging production, the ZB45 packaging machine unit undertakes the crucial automated production of hard-pack cigarette packs. The cutting process of the cardboard (such as the inner lining paper and inner frame paper) directly affects the forming quality and appearance of the cigarette pack. The cardboard plays a positioning and supporting role in the forming of the hard-pack cigarette pack flap. Its processing involves steps such as dotted line cutting, crescent-shaped cutting, and final cutting. In particular, dotted line cutting requires cutting two dotted lines on both sides of the cardboard for folding, and crescent-shaped cutting requires cutting crescent-shaped marks on both sides to support the cigarette pack flap. Therefore, cutting precision is crucial to the quality of cigarette pack packaging.

[0003] In existing technology, the paper cutting component of the ZB45 packaging machine uses a roll-type material cutting method after loading. When the dotted line cutting blade or crescent-shaped cutting blade wears out, the entire inner frame paper scoring mechanism needs to be removed from the main unit. The failed blade and corresponding scoring roller are then disassembled and replaced sequentially. After reinstallation, the blade position and dimensions are adjusted on the machine. During adjustment, the dotted line cutting blade and crescent-shaped cutting blade need to be repeatedly corrected axially and radially according to the scoring effect and length after cutting. Moreover, the entire process lacks precise reference standards and relies on the operator's experience. In the above technical solution, due to the limitations of the equipment structure, the adjustment space is small, and the disassembly, replacement, and installation operations are difficult, requiring highly skilled personnel to perform. A single adjustment takes about 50 minutes, resulting in low equipment production efficiency. Furthermore, the lack of precise standards in the adjustment process can easily lead to quality problems such as scoring that is too deep or too shallow, and scoring spacing that does not meet the 54mm requirement, affecting the quality and appearance of cigarette packaging.

[0004] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this disclosure, and therefore may include information that does not constitute prior art known to those skilled in the art. Utility Model Content

This significantly improves the cutting quality and production efficiency of cigarette packs.

[0006] To achieve the objectives of this application, the following technical solution is provided:

[0007] In a first aspect, this application provides a precision adjustment fixture for paper jam cutting on a ZB45 packaging machine, comprising:

[0017] In one possible implementation, the ZB45 packaging machine paper cutting precision adjustment fixture further includes: a locking mechanism, fixedly mounted on the support mechanism, for fixing and locking the angle and position of the adjustment mechanism.

[0018] In one possible implementation, the locking mechanism includes: a lateral adjustment member and a first fastener; the first fastener is disposed on the lateral adjustment member for locking the angle of the adjustment mechanism, and the lateral adjustment member slides on the support mechanism for moving the first fastener.

[0038] Exemplary embodiments will now be described more fully with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in many forms and should not be construed as limited to the examples set forth herein; rather, they are provided so that this disclosure will be more comprehensive and complete, and will fully convey the concept of the exemplary embodiments to those skilled in the art. The described features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.

[0039] Furthermore, the accompanying drawings are merely illustrative of this disclosure and are not necessarily drawn to scale. The same reference numerals in the drawings denote the same or similar parts, and therefore, repeated descriptions of them will be omitted.

[0040] This example embodiment first provides a precision adjustment fixture for paper jam cutting on a ZB45 packaging machine. (Reference) Figures 1 to 3As shown, the ZB45 packaging machine's precision adjustment fixture for cardboard cutting includes a support mechanism 100, an adjustment mechanism 200, a spacing limiting mechanism 300, and two cutting fixing mechanisms 400. The support mechanism 100 is fixedly connected to the protective shell mounting hole of the ZB45 packaging machine's cutting section 600, providing overall support for the fixture. The spacing limiting mechanism 300 is slidably connected to the support mechanism 100 via the adjustment mechanism 200, limiting the spacing between the two cardboard cutting wheels 610 within the ZB45 packaging machine's cutting section 600 after adjusting the angle and lateral position. The two cutting fixing mechanisms 400 are symmetrically arranged on both sides of the spacing limiting mechanism 300, with their bottom ends fixedly connected to the adjustment mechanism 200 and their top ends having retractable cutting fixing plates 420, which, after adjusting the angle and lateral position, extend to limit the position of the cutting edge of the cardboard cutting wheel 610.

[0041] It is understandable that, such as Figure 2 As shown, the ZB45 packaging machine paper cutting precision adjustment fixture of this application requires, during installation, first removing the protective cover of the ZB45 packaging machine cutting section 600, and then fixing it to the ZB45 packaging machine cutting section 600 through the protective cover mounting holes. The spacing limiting mechanism 300 is engaged between the two paper cutting wheels 610; as Figure 3 As shown, each cardboard cutting wheel 610 is circumferentially spaced with a dotted cutting edge 611 and a crescent-shaped cutting edge 612. The cutting and fixing mechanism 400 is engaged in the gap between the crescent-shaped cutting edge 612 and the dotted cutting edge 611, thereby fixing the position of the cardboard cutting wheel 610; Figure 4 The cut cardstock is shown below. The cut cardstock has spaced-apart dotted cutting lines 710 and crescent-shaped cutting lines 720.

[0042] In one possible implementation, the adjusting mechanism 200 includes: a sliding shaft 210 and a sliding fixed sleeve 220;

[0043] The sliding shaft 210 is fixedly mounted on the support mechanism 100, and the sliding fixed sleeve 220 is slidably mounted on the sliding shaft 210.

[0044] It should be noted that the sliding shaft 210 is fixed to the support mechanism 100 by high-strength bolts, and the inner wall of the sliding fixing sleeve 220 is sanded to increase friction and ensure that the position does not shift after adjustment.

[0045] Furthermore, one end of the spacing limiting mechanism 300 is fixed to the sliding fixing sleeve 220, and the other end is used to extend into the space between the two cardboard cutting wheels 610 inside the cutting section 600 of the ZB45 packaging machine.

[0046] It should be noted that the end of the spacing limiting mechanism 300 that extends between the cutting wheels 610 is provided with a wear-resistant rubber pad to avoid damage to the surface of the cutting wheels by hard contact. Its preset width strictly corresponds to the standard axial spacing of 54mm between the two cutting wheels 610.

[0047] In one possible implementation, the cutting and fixing mechanism 400 includes: a cutting and fixing sleeve 410, a cutting and fixing plate 420, and an extension adjustment member 430;

[0048] The bottom end of the cutting fixing sleeve 410 is fixedly connected to the sliding fixing sleeve 220, the cutting fixing plate 420 is slidably inserted into the cutting fixing sleeve 410, and the extension adjustment member 430 is provided on the cutting fixing sleeve 410 for adjusting the extension length of the cutting fixing plate 420.

[0049] Optionally, the extension adjustment member 430 can be a compression fixing bolt, used to clamp and fix it when it is pulled out to a specified length.

[0050] It should be noted that the cutting fixing plate 420 is equipped with scale markings to facilitate precise adjustment of the extension length.

[0051] Furthermore, the extension adjustment member 430 is a conveying roller, used to drive the cutting fixing plate 420 to extend and retract when rotating.

[0052] It is understandable that the conveyor rollers and the bottom of the cutting fixing plate can be connected by a gear and rack transmission.

[0053] In one possible implementation, the ZB45 packaging machine paper cutting precision adjustment fixture further includes a locking mechanism 500, which is fixedly mounted on the support mechanism 100 and used to fix and lock the angle and position of the adjustment mechanism 200.

[0054] It is understood that the locking mechanism 500 is rigidly fixed to the support mechanism 100. After the adjustment mechanism 200 completes the angle and lateral position calibration, it can prevent parameter deviation caused by equipment operation vibration through mechanical locking, solve the problem of scoring accuracy fluctuation caused by the lack of a precise locking structure in the background technology, and ensure the stability of the cutting wheel spacing and cutting edge position.

[0055] Furthermore, the locking mechanism 500 includes: a lateral adjustment member 510 and a first fastener 520; the first fastener 520 is disposed on the lateral adjustment member 510 for locking the angle of the adjustment mechanism 200, and the lateral adjustment member 510 slides on the support mechanism 100 for driving the first fastener 520 to move.

[0056] It is understood that when the lateral adjustment member 510 slides in the groove of the support mechanism 100, it can drive the first fastener 520 to move synchronously to adapt to the angle locking requirements under different cutting section spatial layouts; the first fastener 520 pushes the pressing and fixing block 522 to press against the surface of the sliding shaft 210 through the rotation of the screw 521, and locks the rotation angle of the adjustment mechanism 200 in the form of friction, avoiding the tedious operation of manually correcting the angle repeatedly in the prior art, and achieving fast and accurate fixing.

[0057] Optionally, the lateral adjustment member 510 includes a sliding block 511 and a second fastener 512; the sliding block 511 is slidably disposed on the support mechanism 100, and the second fastener 512 is disposed on the sliding block 511 for fastening the position of the sliding block 511.

[0058] Optionally, the first fastener 520 includes a screw 521 and a pressing and fixing block 522; the pressing and fixing block 522 is fixed on the screw 521, the sliding block 511 has a threaded hole, and the screw 521 is threaded through the threaded hole.

[0059] It is understood that the screw 521 of the first fastener 520 and the pressing and fixing block 522 can be fixedly connected by key connection, welding, snap-fit ​​or other fixed methods or detachable fixed connection. When the screw 521 is screwed out of the sliding block screw hole, the pressing and fixing block 522 will rise, thereby forming frictional locking with the surface of the sliding shaft 210, and preventing the adjustment mechanism 200 angle from shifting.

[0060] In one possible implementation, the support mechanism 100 further has a groove, the sliding block 511 is slidably disposed in the groove, and the second fastener 512 passes through the groove for pressing and fixing the sliding block 511.

[0061] It is understood that the slide groove of the support mechanism 100 has an open surface on the top surface and the side surface of the support mechanism 100, and the shape of the slide groove corresponds to the sliding block 511. The second fastener 512 is inserted into the open surface on the side surface of the support mechanism 100 and fixes the sliding block 511 by compression.
