DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] In addition, when an element in the present invention is referred to as being "fixed to" or "disposed on" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and are not intended to be the only implementation method.

[0026] See also Figure 1 to Figure 10 In an embodiment of the utility model, a multi-mode switching double-specification four-side embossing mechanism includes: a mounting plate 1, on which two groups of embossing structures are symmetrically arranged, and a top roller 18 is arranged on the mounting plate 1; the embossing structure includes: an upper embossing roller 2 and a lower embossing roller 3, a bottom roller 4, a guide roller 5, a limiting structure and a cleaning kit.

[0027] The upper pattern roller 2 and the lower pattern roller 3 are rotatably installed on the mounting plate 1, and the rotating shafts of the upper pattern roller 2 and the lower pattern roller 3 are connected by a belt 7. Furthermore, the circumferential surfaces of the upper pattern roller 2 and the lower pattern roller 3 can be provided with different concave and convex patterns according to different needs, and the lower pattern roller 3 is connected to a driving motor 11 arranged on the mounting plate 1; the bottom roller 4 is arranged on the mounting plate 1 and is located between the upper pattern roller 2 and the lower pattern roller 3, and the bottom roller 4 has a first state, a second state and a third state switched by being pulled. In the first state, the bottom roller 4 is in contact with the upper pattern roller 2, and in the third state, the bottom roller 4 is in contact with the lower pattern roller 3; specifically, a connecting plate 8 is connected to the rotating shaft of the bottom roller 4, and an end of the connecting plate 8 is connected to a first cylinder 9 arranged on the mounting plate 1, and the first cylinder 9 can drive the bottom roller 4 to move between the upper pattern roller 2 and the lower pattern roller 3 through the connecting plate 8.

[0028] When in use, by controlling the action of the first cylinder 9, the bottom roller 4 can be driven by the connecting plate 8 to perform the lifting action and move between the upper pattern roller 2 and the lower pattern roller 3. At this time, the first state, the second state and the third state are generated correspondingly, and when the bottom roller 4 is in the second state, it is in a separated state from the upper pattern roller 2 and the lower pattern roller 3, that is, the bottom roller 4 is between the upper pattern roller 2 and the lower pattern roller 3, thereby realizing the switching of three different states during paper embossing, so that when producing different types of paper, timely adjustments can be made according to needs without replacing the upper pattern roller 2 or the lower pattern roller 3, reducing the time waste caused by replacing the upper pattern roller 2 or the lower pattern roller 3, and reducing the difficulty of operating the device.

[0029] See also Figure 1~Figure 4 , Figure 6 The guide roller 5 is provided with two groups and is respectively adapted to the upper pattern roller 2 and the lower pattern roller 3. The spacing between the guide roller 5 and the upper pattern roller 2 or the lower pattern roller 3 can be adjusted. The guide roller 5 is provided with a rubber ring to assist the embossing operation and improve the embossing effect. Further, refer to Figure 8~Figure 10 (The dotted line in the figure indicates the direction of paper movement). The paper may not pass through the guide roller 5 (see Fig.10 ) or via guide roller 5 (see Figure 8 , Fig. 9 ), and when passing through the guide roller 5, you can also choose to pass through the guide roller 5 that cooperates with the upper pattern roller 2 (see Fig. 9 ) or select the guide roller 5 that matches with the lower pattern roller 3 (see Figure 8 ) to select the corresponding mode according to actual needs, so as to further improve the embossing effect.

[0030] An adjustment plate 14 is connected to the rotating shaft of the guide roller 5, and a hinge part 1401 rotatably connected to the mounting plate 1 is provided on the adjustment plate 14, and the adjustment plate 14 is connected to the second cylinder 13 provided on the mounting plate 1, and when the second cylinder 13 is actuated, the adjustment plate 14 can drive the guide roller 5 to perform circular motion with the hinge part 1401; the limiting structure is provided on the mounting plate 1, and the limiting structure is used to control the distance between the guide roller 5 and the upper flower roller 2 or the lower flower roller 3 when the guide roller 5 moves to the end of the stroke; the limiting structure includes a limiting block 15 installed on the mounting plate 1, and an adjusting bolt 1501 is provided on the limiting block 15, and the adjusting bolt 1501 can stop the deflection of the adjustment plate 14.

[0031] When in use, by controlling the action of the second cylinder 13, the adjustment plate 14 can be driven to make a circular motion with the hinge part 1401, so that the guide roller 5 can move relative to the upper pattern roller 2 or the lower pattern roller 3 to adjust the distance between the guide roller 5 and the upper pattern roller 2 or the lower pattern roller 3. On the one hand, when there is a larger gap between the guide roller 5 and the upper pattern roller 2 or the lower pattern roller 3, the paper can be placed between the two, thereby reducing the difficulty of placing the paper. On the other hand, by controlling the distance between the guide roller 5 and the upper pattern roller 2 or the lower pattern roller 3, the abutment force between the upper pattern roller 2 or the lower pattern roller 3 and the rubber ring can be changed, so that when the paper moves between the two, different degrees of embossing can be generated, thereby meeting the production requirements of different customers and improving the diversification of embossing production.

[0032] Furthermore, by controlling the length of the adjusting bolt 1501, when the adjusting plate 14 moves to the end of the stroke, the distance between the guide roller 5 and the upper pattern roller 2 or the lower pattern roller 3 can be different, and the adjustment plate 14 can stop moving in time when it moves to the end of the stroke, thereby avoiding the adjustment plate 14 from over-moving under the drive of the second cylinder 13, resulting in excessive abutment force of the guide roller 5 on the upper pattern roller 2 or the lower pattern roller 3, which increases the rotational resistance of the upper pattern roller 2 or the lower pattern roller 3, and even bends and deforms due to pressure.

[0033] See also Figure 1~Figure 5 The cleaning kit is arranged on the mounting plate 1, and the cleaning kit is used to clean the upper pattern roller 2 and the lower pattern roller 3. The cleaning kit includes a connecting bearing 12 rotatably mounted on the mounting plate 1, and a brush roller 6 is rotatably mounted on the connecting bearing 12. The brush roller 6, the guide roller 5, and the rotating shaft of the upper pattern roller 2 are connected by a connecting belt 10; the connecting bearing 12 is also provided with a mounting hole 1201 connected to the mounting plate 1, and an arc groove 1202 is formed on the connecting bearing 12. Specifically, the center of the arc groove 1202 is coaxial with the mounting hole 1201.

[0034] During use, when the driving motor 11 is working, its output shaft can drive the lower pattern roller 3 to rotate. At this time, under the traction of the connecting belt 10, the brush roller 6 can be driven to rotate relative to the upper pattern roller 2 and the lower pattern roller 3, so that the circumferential surface of the upper pattern roller 2 and the lower pattern roller 3 can be scraped to clean the paper scraps and dust adhering to the upper pattern roller 2 and the lower pattern roller 3, prevent the paper scraps and dust from adhering to the upper pattern roller 2 and the lower pattern roller 3 and affecting the subsequent embossing operation, thereby improving the embossing quality.

[0035] Furthermore, as the interaction time between the brush roller 6 and the upper pattern roller 2 and the lower pattern roller 3 increases, the length of the bristles on the brush roller 6 will become shorter. At this time, the connecting bearing 12 is rotated to drive the brush roller 6 to make a circular motion with the mounting hole 1201, thereby shortening the distance between the brush roller 6 and the upper pattern roller 2 and the lower pattern roller 3. Subsequently, the connecting bearing 12 can be fixed by bolts passing through the arc groove 1202, and the distance between the brush roller 6 and the upper pattern roller 2 and the lower pattern roller 3 is fixed again, thereby improving the stability of the brush roller 6 and enabling the brush roller 6 to maintain a stable cleaning state for the upper pattern roller 2 and the lower pattern roller 3.

[0036] See also Figure 7 The sides of the upper and lower pattern rollers 2 and 3 are provided with wetting components 16, and the lower part of the wetting components 16 is provided with a paper dust receiving plate 17 connected to the mounting plate 1, and the paper dust receiving plate 17 can receive the cleaned paper scraps and dust.

[0037] The wetting element 16 can drip oil to lubricate the upper pattern roller 2 and the lower pattern roller 3, so as to prevent the upper pattern roller 2 and the lower pattern roller 3 from interacting with the paper and causing the paper to be entangled.
