[0036] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. In the absence of conflict, the embodiments in this application and the features in the embodiments can be combined with each other. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0037] like Figure 1-7 As shown, the gluing mechanism of the utility model includes:

[0038] Conveying mechanism 1, used for conveying the surface paper to be glued;

[0039] The mounting bracket 2 is arranged at the rear end of the conveying direction of the conveying mechanism 1;

[0040] The lower roller 3 is adjustable up and down and is rotatably mounted on the mounting bracket 2, with a first power member 31 being provided at one end;

[0041] The glue coating roller 4 is rotatably mounted on the mounting bracket 2 and is located above the lower roller 3 , and a second power member 41 is provided at one end;

[0042] The glue coating box 5 is provided on the glue coating roller 4 and is used for coating the glue coating roller 4 with glue.

[0043] By respectively arranging the first power part 31 and the second power part 41 on the lower roller 3 and the glue coating roller 4, the lower roller 3 and the glue coating roller 4 are driven independently, which solves the problem in the prior art that the glue coating roller 4 and the lower roller 3 are connected by a synchronous belt and need to be disassembled and cleaned, and there is no need to re-debug after cleaning; by setting the lower roller 3 to be adjustable up and down, it is possible to adjust the position of the lower roller 3 during cleaning, so as to facilitate the placement of a device for collecting waste water between the glue coating roller 4 and the lower roller 3, and flush the glue coating roller 4 with water through an external water pipe, thereby facilitating the normal cleaning process, and there is no need to disassemble the glue coating roller 4, and no multiple people are required to operate.

[0044] like Figure 2 、 Figure 4-7 As shown, in one embodiment, mounting plates 32 are provided at both ends of the lower roller 3. The mounting plates 32 are slidably mounted on the mounting bracket 2. A third power member 33 is provided below the mounting plates 32 for driving the mounting plates 32 to move up and down. With this design, by providing mounting plates 32 and the third power member 33 at both ends of the lower roller 3, the mounting plates 32 and the lower roller 3 can be driven by the third power member 33 to move vertically on the mounting bracket 2, making it easier to adjust the distance between the lower roller 3 and the glue coating roller 4 when cleaning is required.

[0045] like Figure 6 As shown, preferably, a second guide rail 34 is provided on the mounting plate 32, and a slider 35 adapted to the second guide rail 34 is fixed to the mounting bracket 2. This design facilitates the sliding installation of the mounting plate 32 on the mounting bracket 2 by cooperating with the second guide rail 34 and the slider 35. It should be noted that the cooperation between the guide rail and the slider is equivalent to that of a lead screw guide or a linear bearing, and both can achieve vertical sliding.

[0046] like Figure 5 As shown, in one embodiment, a glue washing pool 6 for collecting waste water during the cleaning process of the glue coating roller 4 is further included, and the bottom of the glue washing pool 6 is connected to a waste water pipe 61. With this design, during the cleaning process, by adjusting the position of the lower roller 3 downward to avoid it, the glue washing pool 6 connected to the waste water pipe 61 is moved to the bottom of the glue coating roller 4, and then the waste water pipe 61 is connected to guide the pipe mouth into the collection bucket or connected to the drainage pipe. The waste water generated during the cleaning process of the glue coating roller 4 can be collected to ensure a clean working environment. After the working cycle is completed, there is no need to disassemble and lift the glue coating roller 4, and the operation can be carried out in situ, saving separate cleaning tools and space.

[0047] like Figure 5 As shown, in one embodiment, both sides of the mounting bracket 2 are provided with engaging grooves 21 for engaging the glue washing tank 6 .

[0048] With this design, by providing the clamping groove 21 , the glue washing tank 6 can be clamped, thereby achieving positioning of the glue washing tank 6 and further facilitating quick installation and removal of the glue washing tank 6 .

[0049] like Figure 1-4 As shown, in one embodiment, the mounting bracket 2 is adjustable left and right on the conveying mechanism 1 .

[0050] This design can adjust the position of the mounting bracket 2 so that the glue coating roller 4 and the lower roller 3 are staggered with the conveying mechanism 1, further facilitating the cleaning process and avoiding contamination of the conveying mechanism 1 during the cleaning process.

[0051] like Figure 2-4 As shown, further, as an embodiment, the rear end of the conveying mechanism 1 is slidably connected to a sliding plate 72, and the mounting bracket 2 is slidably set on the sliding plate 72. The rear end of the conveying mechanism 1 is provided with a first guide rail 71 distributed up and down, and the sliding plate 72 slides on the first guide rail 71. The sliding plate 72 is provided with a third guide rail 73 distributed up and down for the mounting bracket 2 to slide.

[0052] With this design, by setting the sliding plate 72, the installation bracket 2 can be conveniently slidably set on the conveying mechanism 1, and the sliding plate 72 is slidably set on the conveying mechanism 1, which can increase the left and right sliding distance of the installation bracket 2, thereby making the installation bracket 2 and the conveying mechanism 1 more staggered, ensuring that the supporting force extends farther. It should be noted that the guide rail slider can also be replaced by a screw slider and a linear bearing guide rod assembly.

[0053] like Figure 2 、 Figure 4-7 As shown, in one embodiment, the glue roller 4 and the lower roller 3 are each provided with a peeling mechanism 8 to prevent facial tissue from adhering. The peeling mechanism 8 includes a mounting rod 81, each of which is mounted on the mounting bracket 2 at both ends, and a peeling knife 82 mounted on the mounting rod 81. The end of the peeling knife 82 is located near the glue roller 4 or the lower roller 3. This design, by providing the peeling mechanism 8, can prevent facial tissue from adhering to the glue roller 4. In actual use, some glue will inevitably be contaminated on the lower roller 3. In this case, providing the peeling mechanism 8 on the lower roller 3 can effectively prevent facial tissue from adhering to the lower roller 3.

[0054] like Figure 7As shown, in one embodiment, a cleaning assembly 9 for cleaning the lower roller 3 is provided below the lower roller 3. The cleaning assembly 9 includes a cleaning bar 91 for cleaning the lower roller 3 and a fourth power member 92 for driving the cleaning bar 91 to move vertically. In actual use, the lower roller 3 will inevitably be contaminated with some glue. By providing the fourth power member 92 to drive the cleaning bar 91 to rise, the cleaning bar 91 is attached to the surface of the lower roller 3, and the lower roller 3 rotates, so that the cleaning bar 91 can clean the lower roller 3, making it easier to use the lower roller 3 later. It should be noted that the cleaning bar 91 is a rag or a cleaning sponge, etc., which is used to clean the glue adhered to the lower roller 3, further relieving manual labor.

[0055] In one embodiment, a scraper for scraping off excess glue on the glue roller 4 is provided on the bottom plate of the glue coating box 5. This design enables the glue applied on the glue coating roller 4 to be evenly distributed, thereby ensuring the quality of gluing.

[0056] like Figure 1 、 Figure 3 As shown, in one embodiment, it also includes:

[0057] The silo 11 is used to store the facial tissue paper to be glued;

[0058] The transfer mechanism 12 is used to take a single sheet of facial tissue from the hopper 11 and transfer it to the conveying mechanism 1. The transfer mechanism 12 can adopt the suction cup structure, XYZ axis module and robot commonly used in the prior art, so the specific structure is not described here.

[0059] This design facilitates continuous loading of facial tissue by storing the facial tissue to be glued in the hopper 11 and transferring the facial tissue in the hopper 11 to the conveying mechanism 1 through the transfer mechanism 12, so that the gluing process can be carried out continuously.

[0060] It should be noted that the first power member 31 and the second power member 41 include but are not limited to electric motors, motors or rotary cylinders.

[0061] It should be noted that the third power member 33 and the fourth power member 92 include but are not limited to a cylinder, a hydraulic cylinder, a linear guide rail or an electric push rod.

[0062] In the initial state, the mounting bracket 2 is located at the rear end of the conveying mechanism 1. The tissue paper to be glued is placed in the hopper 11. The transfer mechanism 12 takes a single tissue paper from the hopper 11 and transfers it to the conveying mechanism 1. The conveying mechanism 1 conveys the tissue paper between the lower roller 3 and the glue roller 4. The glue box 5 evenly applies glue to the glue roller 4. The scraper at the bottom of the glue box 5 scrapes off the excess glue on the glue roller 4. The glue roller 4 transfers the glue coated on the surface to the tissue paper to be glued. The peeling knife 82 is provided to peel off the tissue paper to prevent the tissue paper from adhering to the glue roller 4 or the lower roller 3. After the tissue paper is glued, it is conveyed to the next process.

[0063] Cleaning of the glue coating roller 4: The sliding plate 72 slides on the first guide rail 71, and the mounting bracket 2 continues to slide on the sliding plate 72, so that the mounting bracket 2 and the conveying mechanism 1 are staggered. The mounting plate 32 is driven to slide on the mounting bracket 2 by the third power member 33, thereby moving the lower roller 3 downward, and the distance between the glue coating roller 4 and the lower roller 3 is increased. The glue washing tank 6 is placed between the glue coating roller 4 and the lower roller 3 along the clamping grooves 21 on both sides, and the glue coating roller 4 is washed through the external water pipe. The waste water after washing falls into the glue washing tank 6 and is discharged through the waste water pipe 61;

[0064] During actual application, it is inevitable that some glue will be contaminated on the lower roller 3. The peeling mechanism 8 provided on the lower roller 3 can prevent the facial paper from adhering to the lower roller 3. However, after the lower roller 3 is contaminated with glue, it needs to be cleaned. In the initial state, the cleaning component 9 is provided on the mounting bracket 2 and is located at the bottom of the lower roller 3. When cleaning the lower roller 3, the cleaning bar 91 is driven upward by the fourth power member 92 until the cleaning bar 91 contacts the lower roller 3, and the lower roller 3 is driven to rotate by the second power member 41. The cleaning bar 91 cleans the lower roller 3 during the rotation of the lower roller 3 to prevent the lower roller 3 from being contaminated with glue.

[0065] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back, etc.), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture. If the specific posture changes, the directional indications will also change accordingly.

[0066] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the present invention, the descriptions of "first", "second", etc. are only for descriptive purposes and cannot be understood as indicating or suggesting their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of such features. In addition, the meaning of "and / or" appearing throughout the text includes three parallel schemes. Taking "A and / or B" as an example, it includes scheme A, or scheme B, or schemes in which A and B are satisfied at the same time. In addition, "multiple" refers to more than two. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in this field to implement. When the combination of technical solutions is mutually contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0067] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations that come within the meaning and range of equivalents of the claims be embraced within the present invention.
