In the cigarette production and processing process, in order to trace back and identify the production information of the cigarette products and prevent the products from counterfeiting, a steel seal identification code needs to be printed outside the cigarette box body, which is an indispensable procedure. The traditional embossed printing device is used for embossing embossed information on the trademark surface of the cigarette box in an axial circumferential rolling mode under the production state of tiling, conveying and feeding before the trademark material of the cigarette box is packaged and formed. The shape of the seal holder of the seal device is generally cylinder, disc or combination of two semicircle blocks, etc., and is fixed on the shaft by taking the shaft as the center, the seal holder is provided with 4-8 digit or letter combined seal bodies along the circular arc direction of the circumferential rotation, and the seal holder is respectively and independently installed and fixed on the seal holder, and the seal device drives the seal bodies on the seal holder to impress digital or letter identification information on label paper which is horizontally paved and conveyed through axial circumferential motion.
The conventional axially and circularly moving steel seal device mainly has the following problems:
firstly, when the seal device is installed, in order to ensure that the seal device and the conveyed label paper keep synchronous in position, the seal device needs to be manually positioned and adjusted, and because the seal seat is fixed on the shaft by taking the shaft as the center, the seal seat needs to be manually and repeatedly loosened, rotated and fastened during adjustment, the accurate alignment of the position can be realized, the adjustment operation is inconvenient, the time consumption is long, and the efficiency is low;
secondly, 4-8 digit or letter steel seal bodies arranged on the steel seal seat are independently fixed by adopting screws one by one, when the steel seal seat is replaced, the installation and adjustment are carried out, so that the quality defects of different stamping marks, blurring or punching of label paper and the like are avoided, the height positions of the steel seal bodies are mainly adjusted one by one manually at present, the adjustment operation is inconvenient, the time consumption is long, the efficiency is low, meanwhile, the traditional steel seal device has no directional installation error-proof function, the installation direction error or the inversion and the like (such as a number 6, a number 9, a number 1, a letter I and the like) are extremely easy to cause in the installation and adjustment process of the steel seal seat and the steel seal bodies, and further the steel seal printing quality accident of batch products is caused, and the huge quality risk hidden danger exists; at present, no good solution exists, and the requirement of the printing quality of the steel seal can be met only through manual repeated adjustment;

Most of the packaging boxes of the cigarette products adopt thin paper boards or balsawood materials, and the feeding mode is integral preforming, so that the steel seal device based on the traditional axial circular motion design cannot meet the steel seal printing matched production process requirements of the integral preforming packaging boxes. Meanwhile, the packaging equipment for the production of the cigarette products of the integral preformed packaging box is also newly changed, the working principle and the working mode of the packaging equipment are different from those of the traditional cigarette packaging equipment, and a new requirement is also provided for the printing mode of the steel seal device, namely, the steel seal device is required to print steel seal information on the appointed stamped surface of the integral preformed packaging box in a straight line vertical stamping mode after the integral preformed packaging box is conveyed to a station in a stepping mode, and the steel seal device designed based on the traditional axial circular motion cannot meet the production matching requirement of the steel seal printing. In addition, according to the cigarette production requirement, part of special cigarette products need to imprint identification code information (generally 4-6 digits or letter combinations) outside the preformed cigarette packaging box, the operation mode is mainly adopted at present, and the manual imprinting position and depth control are difficult to converge, so that the stable control of the printing quality of the identification code is not facilitated, and new requirements are also put forward for the identification code imprinting used in production matching.

The thickness dimension of the concave in the middle of the positioning clamping plate 5 is preferably smaller than the height dimension of the upper long square body of the asymmetric directional steel seal body 4, so that the font printing information surface on the upper part of the asymmetric directional steel seal body 4 can protrude out of the top of the positioning clamping plate 5.
The locating clamping plate 5 is provided with a locating screw hole 52 which is arranged in alignment with the countersunk locating hole 34, countersunk screws 33 are screwed in the countersunk locating hole 34 and the locating screw hole 52, and when the countersunk screws 33 are screwed in, the heads of the countersunk screws 33 do not protrude out of the countersunk positions of the countersunk locating hole 34 so as not to enter the asymmetric trapezoid directional guide groove 32.
In the preferred embodiment, the positioning and locking mechanism 2, the seal holder 3 and the positioning clamp 5 are preferably made of steel or rigid PVC. Preferably, the asymmetrically oriented steel seal body 4 is made of steel material, and the steel material is preferably selected according to the printing object, when the printing object is a thin board or balsa wood material; when the printed object is corrugated board, hard PVC is preferable.
The invention relates to a quick-change self-locking positioning stamping seal device which comprises a telescopic mechanism 1, a positioning locking mechanism 2, a seal seat 3, an asymmetric directional seal body 4 and a positioning clamping plate 5. The telescopic cylinder 11 of the telescopic mechanism 1 is fixedly connected with the machine body of the equipment, and the bottom of the positioning and locking mechanism 2 is fixedly connected with the bottom plate 12 of the telescopic mechanism 1. After the positioning clamp plate 5 is fixedly connected with the seal holder 3 through screws, the asymmetric directional seal body 4 is directionally inserted into the asymmetric directional guide groove 31 of the seal holder 3, and meanwhile, the upper part of the asymmetric directional seal body 4 passes through the rectangular guide groove 51 of the positioning clamp plate, and as the height dimension of the rectangular body at the upper part of the asymmetric directional seal body 4 is larger than the thickness of the concave part in the middle part of the positioning clamp plate 5, the font printing information surface at the upper part of the asymmetric directional seal body 4 can protrude out of the top part of the positioning clamp plate 5; and because the height dimension of the lower part of the asymmetric orientation embossed seal body 4 is the distance from the groove top of the asymmetric trapezoid orientation guide groove 32 of the embossed seal seat to the top plane of the embossed seal seat 3, when the connection assembly of the asymmetric orientation embossed seal body 4, the positioning clamping plate 5 and the embossed seal seat 3 is installed, the asymmetric trapezoid orientation guide groove 32 at the bottom of the embossed seal seat 3 is inserted and installed on the asymmetric trapezoid orientation guide rail 21 of the positioning and locking mechanism 2, the top of the asymmetric trapezoid orientation guide rail 21 of the positioning and locking mechanism 2 naturally contacts with the bottom of the asymmetric orientation embossed seal body 4, and positioning constraint is naturally formed. When the seal holder 3 is inserted into the positioning and locking mechanism 2 and contacts with the limiting block 23, the wedge-shaped automatic rebound stop catch 25 in the locking groove 22 of the positioning and locking mechanism automatically jumps upwards under the action force of the spring 26 to form contact and locking fixed relation with the end face of the seal holder 3, and at the moment, the connection and fixation of the seal holder 3 and the positioning and locking mechanism 2 are completed. After the connection, the fixing and the locking of all the parts of the steel seal device are completed, the steel seal device acts on the preformed packaging box body or the stamped surface of the packaging box body which is fed through the driving of the telescopic mechanism, when the action is completed, the telescopic mechanism retracts to the initial position, namely, the printing of the steel seal is completed, and the action is repeated, so that the steel seal of the next printed body can be printed.
The quick-change self-locking positioning stamping type steel seal device can carry out the adaptive adjustment of the integral installation position according to the feeding direction of a printed object, can print in a vertical reciprocating motion mode, and can print in a parallel reciprocating motion mode, so that the steel seal device is vertical to the printed object.
When the quick-change self-locking positioning stamping type steel seal device is used for replacing steel seal bodies according to production requirements, the steel seal seat 3 is quickly taken down from the positioning locking mechanism 2 in a whole by pressing the wedge-shaped automatic rebound retaining lock catch 25 of the positioning locking mechanism, the steel seal bodies to be replaced are taken out from the asymmetric guide grooves of the steel seal seat 3 to be replaced, the steel seal seat 3 is reloaded on the positioning locking mechanism 2, namely, replacement and installation operations are completed, the newly-loaded steel seal bodies do not need to be subjected to position or height adjustment, and the working efficiency of replacement, installation and adjustment is improved.
Further, when the asymmetric directional embossed seal body 4 is replaced and installed, a directional insertion installation mode is adopted, and as the cross section shape of the lower part of the asymmetric directional embossed seal body 4 is the same as the shape of the asymmetric directional guide grooves longitudinally uniformly distributed on the embossed seal seat, the triangular sharp angle direction of the lower part of the asymmetric directional embossed seal body 4 is consistent with the triangular top sharp angle direction of the asymmetric directional guide groove 31 on the embossed seal seat 3, the uniqueness of the installation direction of the asymmetric directional embossed seal body 4 during directional insertion is realized. And because the height dimension of the lower part of the asymmetric directional embossed seal body 4 is equal to the distance from the groove top of the asymmetric trapezoidal directional guide groove 32 of the embossed seal seat to the top plane of the embossed seal seat 3, after the positioning clamping plate 5 is connected and fixed with the embossed seal seat 3, the bottom surface of the concave part in the positioning clamping plate 5 is naturally contacted with the step surface of the asymmetric directional embossed seal body 4, thereby ensuring the installation height uniformity of the asymmetric directional embossed seal body 4.
Further, after the asymmetric directional steel seal body 4, the positioning clamping plate 5 and the steel seal seat 3 are installed and connected, the connecting assembly can be inserted into the asymmetric trapezoidal directional guide rail 21 of the positioning and locking mechanism 2 through the asymmetric trapezoidal directional guide groove 32 on the steel seal seat 3, at the moment, the bottom surface of the lower part of the asymmetric directional steel seal body 4 and the top of the asymmetric trapezoidal directional guide rail 21 of the positioning and locking mechanism 2 form natural contact, after the steel seal seat 3 and the positioning and locking mechanism 2 are connected and fixed, the integral one-time fixing and locking of a plurality of asymmetric directional steel seal bodies 4 installed on the steel seal seat 3 are also finished, so that the rapid installation and fixation of a plurality of asymmetric directional steel seal bodies 4 are realized, compared with the traditional connection mode that each steel seal body is independently fixed by a screw adopted by an axial and circumferential movement steel seal device, the efficiency is higher, the installation and adjustment time and the workload are reduced, and meanwhile, the problem of uneven steel seal printing due to uneven installation height position is avoided.
When the seal holder 3 is replaced and installed, as the seal holder 3 and the positioning and locking mechanism 2 are in the directional matching connection relationship of the asymmetric trapezoid directional guide rail 21 and the asymmetric trapezoid directional guide groove 32, namely, when the seal holder 3 and the positioning and locking mechanism 2 are in directional matching connection, one side of the asymmetric trapezoid directional guide groove 32 of the seal holder 3 is correspondingly inserted with one side of the asymmetric trapezoid directional guide rail 21 of the positioning and locking mechanism 2, if the directions are opposite, the seal holder 3 and the positioning and locking mechanism 2 cannot be installed, so that the uniqueness of the connection installation direction of the seal holder 3 and the positioning and locking mechanism 2 is ensured, the error-proof function when the seal holder 3 and the positioning and locking mechanism 2 are in directional matching connection is realized, the installation direction and the position uniqueness of the asymmetric directional seal body 4 and the seal holder 3 are ensured, the error-proof function of installation is realized, and the quality risk of output is avoided.
The asymmetric trapezoid directional guide rail 21 of the positioning and locking mechanism 2 and the asymmetric trapezoid directional guide groove 32 of the seal holder 3 are in a connection installation mode of matching with the directional linear guide rail, the insertion end of the asymmetric trapezoid directional guide rail 21 on the positioning and locking mechanism 2 is of an inward inclination angle structural design, rapid insertion of the seal holder 3 is facilitated, efficiency is higher compared with a screw connection fixing mode used by a traditional axial circumferential movement type seal device, workload of installation and adjustment is reduced, and rapid installation is achieved.
When the seal holder 3 is installed and fixed, the positioning and locking mechanism 2 is provided with the limiting block 23 and the automatic rebound thrust lock catch 25, so that the quick installation in place and the locking and fixing can be realized. Namely, when the seal holder 3 is installed into the positioning and locking mechanism 2, when the end face of the seal holder 3 contacts with the positioning face of the limiting block 23 on the positioning and locking mechanism 2, the seal holder is indicated to be installed in place, and the distance from the limiting block 23 of the positioning and locking mechanism 2 to the edge of the locking groove 22 is the same as the length of the seal holder 3, at the moment, the wedge-shaped automatic rebound anti-return lock catch 25 in the locking groove 22 of the positioning and locking mechanism automatically bounces, the wedge-shaped anti-thrust face contacts with the end face of the seal holder 3, and the anti-thrust and fixing functions are generated, so that the rapid positioning, installation and fixing of the seal holder 3 are realized.
The asymmetric directional guide grooves 31 longitudinally and uniformly distributed on the seal holder 3 are triangular and square combined groove bodies, the sharp angle direction of the triangle of the asymmetric directional guide groove 31 is consistent with the sharp angle direction of the triangle at the lower part of the asymmetric directional seal body 4, corresponds to the direction of one side of the asymmetric trapezoid directional guide rail 21 of the positioning and locking mechanism 2, and is consistent with the forward direction mode of numbers or letters at the top of the asymmetric directional seal body 4, thereby ensuring the consistency and the correctness of the connection installation direction among the seal holder 2, the positioning and locking mechanism 1 and the asymmetric directional seal body 4, further ensuring the directional connection installation among the three and the correctness of the seal printing direction, avoiding the problem of reverse seal printing direction and ensuring the seal printing quality.
