[0046] like Figure 1-3 As shown, a fixing mechanism of a box cover of the utility model comprises a bracket 1, a clamping assembly 2, a pressing assembly 3 and a limiting assembly 4, wherein:

[0047] One end of the clamping assembly 2 is fixed to the bottom of the bracket 1, and the clamping assembly 2 has two clamping parts 201, on which the box cover is placed, and the two clamping parts 201 are used to selectively clamp the box cover laterally; one end of the tightening assembly 3 is fixed to the clamping assembly 2, and the other end is used to selectively abut the bottom of the box cover; one end of the limiting assembly 4 is fixed to the bottom of the clamping assembly 2, and the other end is used to selectively abut the top of the box cover.

[0048] In the above structure, two clamping parts 201 are provided to clamp the box cover horizontally, thereby realizing horizontal clamping of the box cover, and the vertical clamping of the box cover is realized by the cooperation of the clamping component 3 and the limiting component 4, and then the box cover is fixed by means of horizontal clamping and vertical clamping, thereby realizing locking of the splicing posture of the box cover, which is beneficial to improving the subsequent splicing quality and reducing the generation of waste products. After the pasting work, the two clamping parts 201 return to their positions, loosening the horizontal clamping of the box cover, and the clamping component 3 and the limiting component 4 return to their positions, loosening the vertical clamping of the box cover.

[0049] like Figure 1 As shown, the fixing mechanism of the box cover is assembled at the second station of the wine box pasting device, and the wine box pasting device is a wine box pasting device disclosed in an automatic pasting device and method (publication number CN110126348A). Specifically, one end of the bracket 1 is used to be fixed on the crossbeam of the pasting device, and the other end is arranged above the second station of the pasting device. After the fixing mechanism of the box cover is installed as a whole, it is located above the second station; Figure 1 In the figure, the position shown at a is the crossbeam of the pasting device, the position shown at b is the second station of the pasting device, and the position shown at c is the box cover conveying mechanism of the pasting device. The box cover conveying mechanism is used to move the box cover from the first station to the second station, and the first station is not drawn in the figure.

[0050] To improve the convenience of installing the box cover fixing mechanism, the structure of the bracket 1 adopts an angle-adjustable structure and a position-adjustable structure, as follows:

[0051] The bracket 1 includes a fixed plate 11, a movable plate 12 and a first bolt 13, wherein one end of the fixed plate 11 is fixedly connected to the crossbeam of the pasting device, and the other end is connected to the movable plate 12 through the first bolt 13; the movable plate 12 and the fixed plate 11 form a vertical flipping structure through the first bolt 13, and the movable plate 12 fixes the flipping angle through the first bolt 13; the clamping assembly 2 is fixed at the bottom of the movable plate 12.

[0052] The movable plate 12 includes an intermediate plate 121, a mounting seat 122, a guide rod 123 and a second bolt 124, wherein one end of the intermediate plate 121 is connected to the fixed plate 11 through the first bolt 13; the side of the mounting seat 122 is fixedly connected to one end of the guide rod 123, and the bottom of the mounting seat 122 is fixedly connected to the clamping assembly 2; two parallel guide rods 123 are provided, and the two guide rods 123 simultaneously penetrate the intermediate plate 121 horizontally; the second bolt 124 is screwed on the intermediate plate 121 and is used to support the side of the guide rod 123.

[0053] In the above structure, the first bolt 13 is used as a hinge shaft and a fastening bolt. Specifically, a first countersunk through hole is set at the position of the first bolt 13 on the side of the middle plate 121, and a threaded hole is set at the position of the first bolt 13 on the side of the fixed plate 11. The first bolt 13 is installed in the first countersunk through hole and screwed in the threaded hole.

[0054] When the inclination angle of the clamping assembly 2 needs to be adjusted, the first bolt 13 is loosened, and the movable plate 12 and the fixed plate 11 can be hinged by the first bolt 13 to adjust the angle. After adjustment, the first bolt 13 is tightened to fix the movable plate 12 and the fixed plate 11 to maintain the adjusted angle.

[0055] The second bolt 124 is a locking component between the middle plate 121 and the guide rod 123 . Specifically, a second countersunk through hole is provided at a position of the middle plate 121 corresponding to the second bolt 124 . One end of the second bolt 124 is screwed into the second countersunk through hole and contacts the surface of the guide rod 123 .

[0056] When the lateral position of the clamping assembly 2 needs to be adjusted, the second bolt 124 is loosened, and the guide rod 123 can slide on the middle plate 121. After the position is adjusted, the second bolt 124 is tightened so that one end of the second bolt 124 abuts against the surface of the guide rod 123, and the guide rod 123 is locked and fixed to the middle plate 121.

[0057] like Figure 2 As shown, the clamping assembly 2 includes a clamping cylinder 21 and a box cover support plate 22, wherein the cylinder body of the clamping cylinder 21 is fixedly connected to the mounting seat 122, the clamping cylinder 21 has two output shafts, each of which is fixedly connected to a box cover support plate 22, one of the output shafts forms a clamping portion 201 with the corresponding box cover support plate 22, and the other output end forms another clamping portion 201 with the corresponding box cover support plate 22; the opposite ends of the two box cover support plates 22 are vertically flanged upward; one end of the clamping assembly 3 and the limiting assembly 4 are fixed on the cylinder body of the clamping cylinder 21.

[0058] When the box cover reaches the two clamping parts 201 , the output shaft of the clamping cylinder 21 drives the two clamping parts 201 to clamp. After clamping, the box cover is clamped between the flanges of the two box cover supporting plates 22 , and the bottom of the box cover contacts the top surface of the box cover supporting plate 22 .

[0059] like Figure 2 As shown, the limiting assembly 4 includes a translation cylinder 41, a connecting frame 42, a base 43 and a pressure plate 44, wherein the connecting frame 42 is fixed on the top of the translation cylinder 41 and the output direction of the translation cylinder 41 is parallel to the guide rod 123, and at the same time, the translation cylinder 41 is arranged below the clamping cylinder 21, and the connecting frame 42 is fixedly connected to the side of the clamping cylinder 21; the output shaft of the translation cylinder 41 is fixedly connected to the base 43; two pressure plates 44 are fixedly arranged at one end of the base 43 close to the bracket 31, and the two pressure plates 44 are symmetrically arranged on both sides of the bracket 31, and the base 43 and the pressure plate 44 are arranged in an L shape.

[0060] After the clamping cylinder 21 clamps the box cover, the output shaft of the translation cylinder 41 drives the pressing plate 44 to reach above the box cover to achieve the limit of the top of the box cover.

[0061] like Figure 2 As shown, the clamping assembly 3 includes a hanger 31 and a lifting cylinder 32, wherein the hanger 31 is in the shape of a Z-shaped plate and is arranged between the two clamping parts 201; one end of the hanger 31 is fixedly connected to the cylinder body of the clamping cylinder 21, and the other end is fixedly connected to the lifting cylinder 32; the output direction of the lifting cylinder 32 is perpendicular to the bottom surface of the box cover support plate 22.

[0062] When the pressing plate 44 reaches above the box cover and is located directly above the lifting cylinder 32, the output shaft of the lifting cylinder 32 extends out and abuts against the bottom of the box cover, cooperating with the pressing plate 44 up and down to clamp the box cover.

[0063] The method of using a fixing mechanism of a box cover of the utility model is as follows:

[0064] After the box cover and the support strip are bonded at the first work station, the box cover conveying mechanism grabs the box cover and translates the box cover between the two clamping parts 201, and makes the bottom surface of the box cover contact with the top surface of the box cover supporting plate 22. After clamping, the box cover conveying mechanism releases the box cover and translates it back to its original position. Then, the clamping cylinder 21 drives the two box cover supporting plates 22 to clamp the side ends of the box cover. After clamping, the output shaft of the translation cylinder 41 extends out to drive the pressing plate 44 to move to the top of the box cover. After that, the output shaft of the lifting cylinder 32 extends out to cooperate with the pressing plate 44 to clamp the box cover. The positioning and locking of the box cover are achieved through the above clamping, ensuring that the box cover is in the correct splicing posture and reducing the generation of waste.

[0065] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
