[0026] The technical scheme in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model and not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative work fall within the scope of the utility model.

[0027] Reference to Figures 1-4 ;

[0028] A fast change roller wheel pressing device, including adjustable roller wheel 12 and fast change roller wheel 4 that have upper and lower corresponding cooperation, adjustable roller wheel 12 is located in the right below fast change roller wheel 4, and the two roller wheels are in the position of alignment and are favorable to the roller pressing small box trademark paper cover plate, and also are favorable to adjustment, and the gap passage for rolling and guiding the folded small box trademark paper is arranged between adjustable roller wheel 12 and fast change roller wheel 4, fast change roller wheel 4 is detachably installed on the transmission shaft 1 in the middle of power roller 5, when installing and using: the central shafts of power roller and adjustable roller wheel are rotatably installed on the support through bearing seat respectively, transmission shaft and synchronous pulley 6 are fixed through fastening screw 7, at this time, synchronous pulley 6, transmission shaft 1 and fast change roller wheel 4 are integrated as a whole;The power of synchronous pulley 6 is transmitted through the power synchronous pulley 11 of equipment main transmission power shaft, so as to transmit power to the end fast change roller wheel 4, and fast change roller wheel 4 drives adjustable roller wheel 12 to rotate.

[0029] Further, the power roller transmission shaft 1 on the quick-change roller 4 installation side is provided with a threaded section 16, the center threaded hole of the quick-change roller 4 is screwed and fixed on the threaded section 16 of the transmission shaft, and the threaded connection structure fixes the quick-change roller 4 and the transmission shaft 1 together as two coaxial parts fixed together through the screw thread to become an integral whole.

[0030] The screw thread screwing direction is the same as the driving transmission direction of the power roller 5. The quick-change roller 4 is provided with a counter-threaded through hole in the center, and the connection part between the threaded section 16 of the transmission shaft 1 and the quick-change roller 4 is provided with a counter-threaded external screw thread. When the transmission shaft transmits power to the quick-change roller, an action force in the same direction is generated, and the quick-change roller generates a counter action force when it is in contact with the small box trademark paper cover edge and is rolled, so that the effect of rolling tighter and tighter is achieved in the rolling process, and the two parts are prevented from being separated during the rolling process. The design of the counter thread is for this purpose. The length of the threaded section 16 is consistent with the width of the quick-change roller 4. The length requirement can make the counter-threaded length of the threaded section 16 flush with the inner end surface of the quick-change roller when it is installed, so as to avoid interference with the belt and other transmission parts of the equipment connecting part due to too long, and insufficient fixation due to too short connection part thread distance.

[0031] Further, the roller pressing part of the adjustable roller 12 is provided with a roller pressing rubber sleeve, which increases the friction between the power roller and achieves the effect of stable conveying of the small box trademark paper. The adjustable roller 12 is an eccentric roller, and the gap between the adjustable roller 12 and the quick-change roller 4 is adjusted through the eccentric shaft of the adjustable roller. The gap between the adjustable roller 12 and the quick-change roller 4 is 0.3-0.4mm.

[0032] The outer end surface of the quick-change roller 4 is distributed with positioning holes 14 for convenient disassembly, and further comprises a disassembly wrench 3, the disassembly wrench 3 is provided with positioning protrusions 15 matched with the positioning holes 14, and the other end of the transmission shaft 1 is provided with a power assembly.

[0033] Further, the positioning holes 14 are counterbores, and are even numbers, which are evenly distributed on the outer end surface of the quick-change roller 4, the disassembly wrench 3 is provided with two symmetrically arranged positioning protrusions 15, and the spacing of the positioning protrusions 15 matches the spacing of the two symmetric positioning holes. As shown in Figure 3 The end part of the quick-change roller 4 is designed with four pin holes with a diameter of 5mm and a depth of 10mm, which are evenly distributed, for matching with the disassembly wrench 3, and after rotating a certain angle, the hole can be repositioned, and the roller can be repeatedly disassembled and installed;

[0034] Further, the power assembly comprises a synchronous pulley 6 mounted on the other end of the power roller transmission shaft 1, which is connected and fixed with the power roller 5 through a fastening screw 7, and is in transmission connection with the power synchronous pulley 11 through a synchronous belt 13, and is provided with a tension pulley 10 in the middle. The end of the transmission shaft 1 of the installation end of the power assembly is provided with a hand wheel 9 for conveniently dismounting and fastening the synchronous pulley, and is fixed through a locking jackscrew 8.

[0035] The working process is: after the small box trademark paper is folded through the spiral guide rail, it enters the middle position between the quick-change roller 4 and the adjustable roller 12, the distance between the two rollers is the thickness of a trademark paper, and after the roller pressing of the two rollers, the cover edge folding of the small box trademark paper can be realized, as shown in the following A-F: Figure 4

[0036] A, small box glue coating and conveying;

[0037] B, the cover edge is folded to 90° through the track;

[0038] C, the cover edge is folded to 60° through the track;

[0039] D, the cover edge is folded to 30° through the track;

[0040] E, the cover edge is folded to 15° through the track;

[0041] F, the cover edge is folded to 180° through the track;

[0042] The trademark paper after the above folding is pressed to prevent it from being inserted into the cigarette package after folding and causing product quality defects.

[0043] When disassembling, one hand holds the hand wheel and the other hand rotates the disassembly wrench 3 clockwise to disassemble the quick-change roller 4 without disassembling the compaction mechanism assembly and the transmission device inside the transmission box.
