The correction surface is the upper surface of the correction block, which is used to contact the working surface of the lower short edge folder and to mark a correction line for verifying whether the lower short edge folder is deformed. The correction line coincides with the edge line of the working surface of the non-deformed and failed lower short edge folder away from the first seat body.

[0008] In some embodiments, the folder calibration tool further includes an adjusting member, which connects the correction block and the second seat body and adjusts the position of the correction block so that the upper surface of the correction block contacts the working surface of the lower short edge folder.

[0009] In some embodiments, the adjustment member adjusts the height position of the correction block.

[0010] In some embodiments, the adjusting member adjusts the height position of the correction block by adjusting the distance between the correction block and the second base in the up and down directions; and / or, the adjusting member adjusts the height position of the correction block by adjusting the distance between the correction block and the second base and the surface supporting the folder calibration tooling in the up and down directions.

[0035] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means intended to limit the present application and its application or use. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without carrying out creative work are within the scope of protection of this application.

[0036] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered as part of the specification.

[0037] In the description of the present application, it should be understood that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of the present application.

[0038] In addition, the technical features involved in the different embodiments of the present application described below can be combined with each other as long as they do not conflict with each other.

[0039] During the cigarette packing process, it is usually necessary to fold the label paper multiple times. For example, it is usually necessary to fold the four long sides and two short sides of the label paper in sequence. Accordingly, the packaging machine is usually equipped with multiple folders to complete the multiple folding of the corresponding label paper.

[0040] Among them, in order to complete the folding of the lower short edge of the trademark paper, the packaging machine is provided with a lower short edge folder. For example, in the GDX6 (S) packaging machine, the lower short edge folder is arranged on the third wheel, specifically at the bottom of the third wheel, for folding the lower short edge of the trademark paper.

[0041] Compared with other folders, the structure of the lower short side folder is more complex and special.

[0042] Figure 1-Figure 3 The structure of the lower short edge folder is shown.

[0043] See also Figure 1-Figure 3 The lower short edge folder 5 has a mounting section 53 and a working section 54. The mounting section 53 is used to connect with a structure (referred to as a support member) on the packaging machine for mounting the lower short edge folder 5, so as to realize the installation of the lower short edge folder 5 on the packaging machine. The working section 54 is connected to the mounting section 53 at an angle, and contacts the trademark paper through a working surface 51 located at one end away from the mounting section 53, so as to complete the folding of the lower short edge.

[0044] Specifically, see Figure 2 and Figure 3 The mounting section 53 is generally in the shape of a flat plate, and is provided with a through hole 55, through which the mounting section 53 is connected to the support member. During installation, a connecting member 7 such as a screw passes through the through hole 55 and is inserted into a corresponding hole of the support member to connect the mounting section 53 with the support member, thereby completing the installation of the lower short edge folder 5 on the packaging machine. Figure 2 and Figure 4 It can be seen that the through holes 55 are long holes, and there are four of them. The four through holes 55 are divided into two groups. The two groups of through holes 55 are arranged at intervals along the second direction Y, and each group of through holes 55 includes two through holes 55. The two through holes 55 in each group of through holes 55 are arranged at intervals along the first direction X. The first direction X and the second direction Y are perpendicular to each other and are perpendicular to the thickness direction of the installation section 53 (which is also the up-down direction Z after being installed on the packaging machine). At the same time, by Figure 3It can be seen that the mounting section 53 is further provided with a groove 52 at the position of one group of through holes 55, and the two through holes 55 at the corresponding position are both located in the groove 52. In the process of mounting on the support, a protrusion is provided on the support, and the protrusion is embedded in the groove 52 to limit the lower short edge folder 5, so that the lower short edge folder 5 can be mounted on the support more stably.

[0045] like Figure 2 and Figure 3 As shown, the working section 54 is a curved plate, which is connected to one end of the mounting section 53 and is bent toward one side in the thickness direction by the mounting section 53. The end of the working section 54 away from the mounting section 53 is a free end, and its end surface constitutes a working surface 51 for contacting the trademark paper.

[0046] Among them, the angle of the working surface 51 (such as Figure 1 and Figure 2 center line a) and straightness (as shown Figure 2 and Figure 3 The folding effect of the lower short side of the cigarette pack (shown by the center line b) directly affects the folding effect of the lower short side of the cigarette pack and the adhesion effect of the bottom of the cigarette pack, and also indirectly affects the folding effect of the upper short side of the bottom of the cigarette pack. The angle and straightness of the working surface 51 will change when the lower short side folder 5 is deformed and fails, and no longer meet the requirements. Therefore, whether the lower short side folder 5 is deformed and fails has an important impact on the folding effect of the short side of the cigarette pack and the adhesion effect of the bottom of the cigarette pack. When there are problems with the folding effect of the short side of the cigarette pack and the adhesion effect of the bottom of the cigarette pack, it is necessary to determine whether it is due to the deformation and failure of the lower short side folder 5 in order to perform troubleshooting and maintenance.

[0047] Since the structure of the lower short side folder 5 is relatively complex and its position is relatively special, it is difficult to determine by visual inspection whether it has deformed and failed, and whether the angle and straightness of its working surface 51 cannot meet the requirements. It is also impossible to determine by visual inspection of the relative position relationship between the working surface 51 of the lower short side folder 5 and other components (such as the elastic sheet at the bottom of the No. 3 wheel mold box and other lower short side folders), or by other methods such as feeler gauge measurement. At the same time, the related technology also lacks a folder inspection tool that can detect whether the lower short side folder 5 is deformed. Therefore, how to judge whether the lower short side folder 5 has deformed and failed has always been a difficult problem. In the related technology, usually only when problems such as poor folding of the bottom of the cigarette pack occur and it is suspected that it is related to the lower short side folder 5, a new lower short side folder 5 is directly replaced to eliminate the influencing factors caused by the failure of this part. However, this method not only increases the loss rate of spare parts, but also greatly shortens the service life of repairable parts, resulting in waste and increased costs.

[0048] It can be seen that in the related art, it is difficult to effectively determine whether the lower short edge folder is deformed and fails, which will increase the difficulty of troubleshooting, prolong the troubleshooting and maintenance time, increase the troubleshooting and maintenance costs, and affect work efficiency.

[0049] In response to the above situation, the present application provides a folder calibration tool to calibrate and correct the lower short edge folder, so as to facilitate the judgment of whether the lower short edge folder is deformed and failed, thereby reducing the difficulty of troubleshooting, shortening the troubleshooting and maintenance time, saving troubleshooting and maintenance costs, and improving work efficiency.

[0050] Figure 1 as well as Figure 4 and Figure 5 The folder inspection tool of the present application is shown as an example.

[0051] First of all, it should be noted that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "horizontal, vertical, vertical, horizontal" and "top, bottom" are usually based on the attached Figure 1 and Figure 4 The orientation or position relationship shown, and attached Figure 1 and Figure 4 The orientation or position relationship shown is consistent with the orientation or position relationship of the folder verification tooling and the lower short edge folder during normal use, wherein the up-down direction Z is along the direction of gravity, "up" is opposite to the direction of gravity, and "down" is the same as the direction of gravity, and the first direction X and the second direction Y are two horizontal directions, which are perpendicular to each other and both perpendicular to the up-down direction Z.

[0052] See also Figure 1 as well as Figure 4 and Figure 5 The folder calibration tool 10 provided in the present application includes a base 1 and a calibration block 3. The base 1 includes a first base body 11 and a second base body 12, the first base body 11 and the second base body 12 are connected side by side along a first direction X, and the upper surface of the first base body 11 is higher than the upper surface of the second base body 12, and the upper surface of the first base body 11 is used to install the lower short edge folder 5. The calibration block 3 is arranged on the upper surface of the second base body 12 and has a calibration surface 31. The calibration surface 31 is the upper surface of the calibration block 3, which is used to contact with the working surface 51 of the lower short edge folder 5, and is used to mark a calibration line 32 for calibrating whether the lower short edge folder 5 is deformed and invalid. The calibration line 32 coincides with the edge line (referred to as the outer edge line) of the working surface 51 of the undeformed lower short edge folder 5 away from the first base body 11.

[0053] Based on the above settings, the folder verification tool 10 can be used to conveniently verify and calibrate the lower short edge folder 5 to determine whether the lower short edge folder 5 is deformed and failed, and whether the angle and straightness of its working surface 51 meet the requirements.

[0054] When using it for the first time, a new, undeformed lower short edge folder 5 can be installed on the first seat body 11 of the base 1, and the correction block 3 on the second seat body 12 of the base 1 can be effectively (lightly and evenly) contacted with the working surface 51 of the corresponding lower short edge folder 5. Then, on the correction surface 31 of the correction block 3, a drawing tool such as a drawing needle is used to draw a line along the outer edge line of the working surface 51 of the lower short edge folder 5 to form a correction line 32. Finally, the corresponding lower short edge folder 5 is removed to complete the zero adjustment of the folder calibration tool 10.

[0055] Since the lower short edge folder 5 used in the above-mentioned zero adjustment process is new and has not been deformed, the drawn correction line 32 corresponds to the outer edge line of the working surface 51 of the undeformed lower short edge folder 5. In other words, if the lower short edge folder 5 is not deformed and the angle and straightness of its working surface 51 meet the requirements, then the outer edge line of its working surface 51 should coincide with the correction line 32. If they do not coincide, it means that the lower short edge folder 5 has been deformed and failed, and the angle and straightness of its working surface 51 no longer meet the requirements.

[0056] Therefore, after zeroing, when the cigarette pack bottom is poorly folded and the like occurs, and after preliminary judgment, it is related to the failure of the lower short side folder 5, the folder inspection tool 10 can be used to inspect the lower short side folder 5. When in use, it is only necessary to remove the target lower short side folder 5 from the whole machine, and then install it on the base 1, and compare whether the outer edge line of its working surface 51 coincides with the correction line 32, so as to quickly and accurately determine whether the corresponding lower short side folder 5 is deformed and failed, thereby reducing the difficulty of troubleshooting, improving the accuracy of troubleshooting, shortening the troubleshooting and maintenance time, reducing the replacement of spare parts, saving costs, and improving efficiency.

[0057] It can be seen that the provided folder verification tool 10 can conveniently detect whether the lower short side folder 5 is deformed and fails, which can effectively shorten the troubleshooting and maintenance time, while saving maintenance costs and improving work efficiency.

[0058] To further facilitate the aforementioned zero adjustment operation, see Figure 1 and Figure 4 In some embodiments, the folder calibration tool 10 includes not only a base 1 and a calibration block 3, but also an adjustment member 4. The adjustment member 4 connects the calibration block 3 with the second base 12 and adjusts the position of the calibration block 3 so that the upper surface of the calibration block 3 contacts the working surface 51 of the lower short edge folder 5.

[0059] Based on the adjustment member 4, the position of the correction block 3 can be flexibly adjusted during the zero adjustment process so that the upper surface of the correction block 3 contacts the working surface 51 of the lower short edge folder 5. In particular, the position of the correction block 3 can be adjusted so that the upper surface of the correction block 3 contacts the working surface 51 of the lower short edge folder 5 more lightly and evenly. In this way, not only a more convenient and efficient quality adjustment process can be achieved, but also a more accurate correction line 32 can be obtained, thereby achieving a more accurate correction process.

[0060] The position of the correction block 3 adjusted by the adjusting member 4 may be a height position or a horizontal position, or may include both a horizontal position and a height position. When the adjusting member 4 only adjusts the height position of the correction block 3 but does not adjust the horizontal position of the correction block 3, it can meet the adjustment requirements and simplify the adjustment process and the structure of the adjusting member 4.

[0061] When the adjusting member 4 adjusts the height position of the correction block 3, the adjusting member 4 can adjust the height position of the correction block 3 by adjusting the distance between the correction block 3 and the second seat body 12 in the up-down direction Z. At this time, the height between the correction block 3 and the upper surface of the second seat body 12 is adjustable, and the adjusting member 4 is actuated to drive the correction block 3 to rise and fall relative to the second seat body 12, change the distance between the correction block 3 and the upper surface of the second seat body 12, and make the correction block 3 approach or move away from the upper surface of the second seat body 12 in the up-down direction Z, thereby changing the height position of the correction block 3 and adjusting the contact between the correction block 3 and the working surface 51.

[0062] Alternatively, the adjusting member 4 can also adjust the height position of the correction block 3 by adjusting the distance between the correction block 3 and the second seat body 12 and the surface of the support folder inspection tool 10 (for example, the ground or a tabletop, which can be referred to as a supporting surface) in the vertical direction Z. At this time, the height between the correction block 3 and the second seat body 12 and the surface of the support folder inspection tool 10 is adjustable, and the adjusting member 4 is actuated to drive the correction block 3 and the second seat body 12 to rise and fall relative to the surface of the support folder inspection tool 10, change the distance between the correction block 3 and the second seat body 12 and the surface of the support folder inspection tool 10, and make the correction block 3 and the second seat body 12 move together in the vertical direction Z close to or away from the surface of the support folder inspection tool 10, thereby changing the height position of the correction block 3 and adjusting the contact between the correction block 3 and the working surface 51.

[0063] Of course, in some embodiments, the adjustment member 4 can also adjust the height position of the correction block 3 by adjusting the distance between the correction block 3 and the second seat body 12 in the up and down direction Z, and adjusting the distance between the correction block 3 and the second seat body 12 and the surface supporting the folder calibration tooling 10 in the up and down direction Z.

[0064] As an example of the adjusting member 4 in the above-mentioned embodiments, see Figure 1 and Figure 4 The adjusting member 4 includes a threaded connector 41 such as a bolt. At this time, the position of the correction block 3, especially the height position, can be adjusted by simply screwing the adjusting member 4, which is simple and convenient. Moreover, the structure of the adjusting member 4 is also simple and the cost is low.

[0065] In addition, in the above-mentioned embodiments, the number of the adjusting members 4 is not limited, and can be one, two or more. Figure 1 and Figure 4 In some embodiments, the folder calibration tool 10 includes two adjustment members 4, which are arranged at intervals along the second direction Y. This is conducive to more stable zero adjustment and more accurate correction line 32, thereby achieving a more accurate correction process.

[0066] In the above-mentioned embodiment with the adjusting member 4, see Figure 1 and Figure 4 The folder inspection tool 10 may further include a locking member 6 (not shown), which locks the calibration block 3 at the position adjusted by the adjusting member 4. In this way, during the zero adjustment process, after the adjusting member 4 adjusts the calibration surface 31 to effectively contact the working surface 51, the locking member 6 is used to lock the calibration block 3 so that the calibration block 3 is stably maintained at the corresponding position, and then the line is drawn to mark the calibration line 32. This can effectively prevent the calibration block 3 from shifting during the line drawing and subsequent actual verification process, affecting the line drawing and verification accuracy, and therefore is conducive to further improving the verification and correction accuracy.

[0067] See also Figure 1 As an example of the locking member 6, the locking member 6 includes a nut 61. In particular, when the adjusting member 4 includes a threaded connector 41, the locking member 6 includes the nut 61. The desired locking can be achieved by simply screwing the nut 61 onto the threaded connector 41, which is simple and convenient.

[0068] In the above embodiments, in order to realize the connection between the first seat body 11 and the lower short edge folder 5, see Figure 1 as well as Figure 4 and Figure 5 A first mounting position 15 and a second mounting position 16 may be provided on the upper surface of the first base body 11, and the first mounting position 15 and the second mounting position 16 are arranged at intervals along the second direction Y. The first base body 11 is connected to the lower short edge folder 5 at the first mounting position 15 and the second mounting position 16 to realize the installation of the lower short edge folder 5 on the first base body 11.

[0069] As mentioned above, when actually installed on the packaging machine, the lower short edge folder 5 is connected to the support member through two groups of through holes arranged at intervals along the second direction Y. Therefore, two mounting positions arranged at intervals along the second direction Y are provided on the first seat body 11, namely the first mounting position 15 and the second mounting position 16, which is conducive to more realistically simulating the actual installation situation of the lower short edge folder 5. In particular, the first mounting position 15 and the second mounting position 16 can be made to correspond one-to-one with the two groups of through holes of the lower short edge folder 5, and the first mounting position 15 and the second mounting position 16 are both provided with two first mounting holes 13 arranged at intervals along the first direction X and corresponding one-to-one with the two through holes in each group of through holes of the lower short edge folder 5, so as to more realistically simulate the actual installation situation of the lower short edge folder 5. In this way, it is conducive to improving the correction accuracy and realizing a more accurate correction process.

[0070] Furthermore, to further improve the correction accuracy, see Figure 4 and Figure 5 In some embodiments, the folder calibration tool 10 also includes a limit block 2, which is arranged at the first mounting position 15 and protrudes upward relative to the upper surface of the first seat body 11, and is used to be embedded in the groove 52 of the lower short edge folder 5.

[0071] Since the limit block 2 is able to simulate the protrusion on the support member for embedding in the groove 52 of the lower short edge folder 5 under the actual installation environment mentioned above, therefore, providing a protruding limit block 2 on the first seat body 11 for embedding in the groove 52 of the lower short edge folder 5 can more realistically simulate the actual installation situation of the lower short edge folder 5 and further improve the correction accuracy.

[0072] Next, combine Figure 1-Figure 5 The present application is further illustrated by the embodiments.

[0073] like Figure 1-Figure 5 As shown, in this embodiment, the folder calibration tool 10 includes a base 1, a limit block 2, a correction block 3, two threaded connectors 41 and two nuts 61 (not shown).

[0074] The base 1 includes a first base body 11 and a second base body 12, both of which are in a cubic shape. The first base body 11 and the second base body 12 are arranged side by side along the first direction X and connected to each other in an L shape. The lower surfaces of the two are flush, and the upper surface of the first base body 11 is higher than the upper surface of the second base body 12, which is adapted to the characteristic that the mounting section 53 of the lower short side folder 5 is higher than the working surface 51. A first mounting position 15 and a second mounting position 16 are provided on the upper surface of the first base body 11. The first mounting position 15 and the second mounting position 16 are arranged at intervals along the second direction Y and correspond to the two groups of through holes on the lower short side folder 5 one by one, respectively. Moreover, two first mounting holes 13 are provided at the first mounting position 15 and the second mounting position 16. The two first mounting holes 13 at the first mounting position 15 and the second mounting position 16 are arranged at intervals along the first direction X and correspond to the two through holes in the corresponding group of through holes one by one. At the same time, a limit block 2 for cooperating with the groove 52 on the lower short edge folder 5 is also provided at the first mounting position 15. The limit block 2 protrudes upward from the upper surface of the first seat body 11, and the limit block 2 covers the two first mounting holes 13 at the first mounting position 15. At the same time, the limit block 2 is provided with a second mounting hole 21 which is connected to the two first mounting holes 13 at the first mounting position 15 in a one-to-one correspondence.

[0075] Based on the provided base 1, two connecting members 7 (such as screws) are passed through the two through holes on the lower short edge folder 5 and the two second mounting holes 21 and the two first mounting holes 13 at the first mounting position 15, and another two connecting members 7 (such as screws) are passed through the other two through holes on the lower short edge folder 5 and the two first mounting holes 13 at the second mounting position 16, thereby completing the installation of the lower short edge folder 5 on the folder verification tooling 10. This is simple and convenient, and can accurately simulate the actual installation situation of the lower short edge folder 5 in the packaging machine.

[0076] The calibration block 3 is a cubic aluminum block, which is connected to the second base body 12 of the base 1 through two threaded connectors 41. Figure 4 and Figure 5 As shown, the second seat body 12 is provided with two connecting holes 14, which are arranged at intervals along the second direction Y. Correspondingly, the correction block 3 is provided with two assembly holes (not shown), which are arranged at intervals along the second direction Y and are connected to the two connecting holes 14 in a one-to-one correspondence. Two threaded connectors 41 pass through two pairs of interconnected connecting holes 14 and assembly holes, respectively, to connect the correction block 3 with the second seat body 12, and realize the installation of the correction block 3 on the second seat body 12.

[0077] In this embodiment, the two threaded connectors 41 are bolts, and the lower ends of both extend from the lower surface of the second base body 12. In this way, the two threaded connectors 41 can not only realize the connection between the correction block 3 and the second base body 12, but also adjust the height of the second base body 12 and the correction block 3 from the ground (that is, the height between the second base body 12 and the correction block 3 and the surface of the support folder calibration tooling 10), change the height position of the correction block 3, and adjust the contact between the correction block 3 and the working surface 51 of the lower short edge folder 5. At this time, the two threaded connectors 41 of this embodiment are used as two adjustment members 4.

[0078] The two threaded connectors 41 are respectively equipped with a nut 61, which is used to be screwed onto the two threaded connectors 41 for locking and fixing when the two threaded connectors 41 adjust the correction block 3 to be in good contact with the working surface 51. At this time, the two nuts 61 are used as two locking members 6.

[0079] Based on the folder verification tool 10 of this embodiment, the lower short edge folder 5 can be easily verified and calibrated to determine whether the lower short edge folder 5 is deformed and failed, and whether the angle and straightness of its working surface 51 meet the requirements.

[0080] Specifically, when using it for the first time, a new lower short edge folder 5 can be installed on the first seat body 11 of the base 1, and then the correction block 3 can be adjusted to be in uniform contact with the working surface 51 of the corresponding lower short edge folder 5 using two threaded connectors 41. Subsequently, on the correction surface 31 of the correction block 3, the outer edge line of the working surface 51 of the lower short edge folder 5 can be drawn onto the correction surface 31 using a drawing pin to form a correction line 32. Finally, the corresponding lower short edge folder 5 is removed to complete the zero adjustment of the folder calibration tool 10.

[0081] Afterwards, when the cigarette pack bottom has a bad folding and the like, and it is preliminarily determined that it is related to the failure of the lower short side folder 5, or when it is necessary to verify whether the machined lower short side folder 5 has been restored to the usable standard after machining the failed lower short side folder 5, the folder verification tool 10 can be used to inspect the lower short side folder 5. During the verification, it is only necessary to install the target lower short side folder 5 on the base 1 and compare whether the outer edge line of its working surface 51 coincides with the correction line 32, so as to quickly and accurately determine whether the corresponding lower short side folder 5 has deformed and failed, thereby reducing the difficulty of troubleshooting, improving the accuracy of troubleshooting, shortening the troubleshooting and maintenance time, reducing the replacement of spare parts, saving costs, and improving efficiency.

[0082] It can be seen that the folder verification tool 10 of this embodiment can conveniently detect whether the lower short edge folder 5 is deformed and fails, which can effectively save troubleshooting and maintenance time caused by the deformation and failure of the lower short edge folder 5, while saving maintenance costs and improving work efficiency.

[0083] The above description is only an exemplary embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
