Description

Technical Field

[0002] A window pasting machine, also known as a carton window film pasting machine, is mainly used for local gluing and film pasting of windowed cartons. A window pasting machine usually consists of structures such as a paper feeding part, a gluing part, a film pasting part, and a bonding part, including several steps such as paper feeding, gluing, film pasting, and bonding, and is applicable to the film pasting of various windowed gift boxes, cosmetic boxes, tissue boxes, windowed corrugated cartons, etc.

[0003] Among them, the gluing part is used to apply glue to the paper so that the film can be adhered to the paper in the subsequent film pasting part. The existing gluing part is usually fixedly installed on the frame of the window pasting machine, and its gluing roller is in contact with the conveyor belt of the paper feeding mechanism. When the paper passes under the gluing roller, the gluing work is achieved.

[0004] For example, a gluing mechanism disclosed in CN211334831U and published on August 25, 2020. In the prior art, a cylinder is used to push the gluing mechanism to perform lifting motion, which has disadvantages such as poor accuracy and slow action speed. Summary of the Utility Model

[0031] The embodiments of the present utility model will be further described below in conjunction with the accompanying drawings:

[0032] As shown in the figure, an eccentric wheel reciprocating motion mechanism of a gluing part of a window pasting machine includes a gluing assembly 2 and a bracket 3, and further includes:

[0033] A gluing large plate 13, which is vertically slidably installed on the bracket 3 and is used for installing the gluing assembly 2;

[0034] An eccentric wheel shaft, which includes a rotating shaft 42 rotatably installed on the bracket and several eccentric wheels 43 sleeved on the rotating shaft;

[0035] A linkage member, one end of which is rotationally matched with the eccentric wheel and the other end of which is hinged to the gluing large plate 13; when the eccentric wheel shaft of this technical solution rotates, it will drive the gluing assembly to perform reciprocating lifting motion through the linkage member, which has the advantages of high working precision, continuous motion and fast working speed.

[0036] A first driving member 41 for driving the rotation of the rotating shaft 42 is provided on the bracket. The first driving member uses a servo motor. The servo motor rotates to drive the rotation of the rotating shaft. The rotation of the rotating shaft makes the two eccentric wheels installed on the eccentric wheel shaft rotate synchronously. Among them, the rotating shaft drives the eccentric wheels to rotate synchronously through a flat key, and the eccentric wheels drive the gluing large plate to perform up and down reciprocating motion through the linkage member.

[0037] The gluing assembly 2 includes two relatively arranged lower side plates 11 and a connecting plate 12 fixedly connected between the lower side plates; several first slide rail modules 14 that are horizontally slidably matched are provided between the gluing large plate 13 and the connecting plate 12. The gluing assembly is installed on the gluing large plate. The first slide rail module is an off-the-shelf part, which effectively ensures the sliding motion precision of the gluing assembly on the gluing large plate;

[0038] The gluing assembly 2 further includes:

[0039] An upper side plate 15, which is hingedly installed above the lower side plate 11;

[0040] A second driving member 16 for hingedly connecting the upper side plate 15 and the lower side plate 11 is provided between the upper side plate 15 and the lower side plate 11. The second driving member uses a cylinder, an oil cylinder or a linear motor. The second driving member makes a piston motion to adjust the included angle between the upper side plate and the lower side plate;

[0041] In this embodiment, the lower side plate is for installing a glue applying roller, and the upper side plate is for installing a glue supply roller. The specific structures of the glue applying roller and the glue supply roller in this embodiment are approximately the same as the structural principle of the gluing mechanism in CN211334831U, and can be referred to, and will not be elaborated here.

[0042] The bracket 3 is provided with an adjusting component for adjusting the lateral position of the glue - applying component. The adjusting component includes:

[0043] A fixed plate 31, which is fixedly installed on the rear side wall of the glue - applying large plate 13;

[0044] A lead screw 32, which is rotatably installed on the fixed plate 31;

[0045] A movable plate 33, which is provided with a fixedly installed nut sleeve 35 and a pin 34 inserted into the connecting plate 12;

[0046] The lead screw 32 is in threaded cooperation with the nut sleeve 35. When the lead screw rotates, it drives the movable plate to move laterally through the nut sleeve. The movable plate drives the entire mounting plate assembly to move laterally through the pin. The forward and reverse rotation of the lead screw can drive the mounting plate assembly to move left and right in the horizontal direction.

[0047] The glue - applying large plate 13 is provided with several horizontally arranged guide shafts 36 that are slidably matched with the movable plate 33. The guide shafts provide a guiding function for the sliding of the movable plate, ensuring the smoothness of the displacement and the movement accuracy.

[0048] The linkage includes:

[0049] An eccentric bearing sleeve 44, which is sleeved on the outer circumference of the eccentric wheel;

[0050] A spherical plain bearing 45, one end of which is hinged to the glue - applying large plate 13;

[0051] A screw rod 46 is fixedly connected between the other end of the spherical plain bearing 45 and the eccentric bearing sleeve 44. The eccentric bearing sleeve and the eccentric wheel rotate relative to each other. The eccentric wheel is driven by the rotating shaft to rotate, and the glue - applying large plate is driven to make a reciprocating lifting motion through the linkage.

[0052] On both side walls of the bracket 3, there are vertically arranged second slide - rail modules 37 that are slidably matched with the glue - applying large plate 13. The second slide - rail modules are off - the - shelf components with the advantage of high working accuracy.

[0053] A handwheel 38 is provided at the end of the lead screw 32 for rotating the lead screw.
