Technical Field

[0001] The utility model relates to the technical field of packaging material processing, in particular to a glue coating mechanism. Background Art

[0002] Packaging materials include pearl cotton, cardboard, polyethylene, polyvinyl chloride, etc. Taking pearl cotton as an example, pearl cotton has many advantages such as water-proof and moisture-proof, shockproof, soundproof, heat-insulating, good plasticity, strong toughness, recycling, environmental protection, strong impact resistance, etc. It also has good chemical resistance and is an ideal packaging material. Most of the existing packaging materials have the limitation of non-plasticity, and many packaging materials need to undergo a series of tedious processing before they can be formed, and the key step requires bonding equipment.

[0003] The bonding equipment will first apply glue to the package through the glue coating structure, and then bond the two packages together by pressing. The existing glue coating mechanism usually injects glue into the glue coating roller and applies the glue to the outside of the glue coating roller by rotation. However, the amount of glue that can be accommodated in the existing glue coating roller is insufficient, resulting in the glue being unable to completely cover the outside of the glue coating roller. Therefore, the glue often appears unevenly applied to the package, which in turn affects the bonding effect. Utility Model Content

[0005] The glue roller has insufficient glue capacity, which results in uneven glue coating and affects the bonding effect.

[0010] Wherein, the top end of the glue coating roller close to the glue injection component is flush with the top end of the glue leveling roller close to the glue injection component.

[0012] In one embodiment, the adjusting rod passes through the mounting frame and is connected to the pressing block, and the adjusting rod is threadedly connected to the mounting frame.

[0013] In one embodiment, the glue spreading assembly also includes a guide rod; one end of the guide rod is connected to the slide seat, the other end of the guide rod passes through the pressure block, the guide rod is movably connected to the pressure block, and the elastic member is arranged around the outer side of the guide rod.

[0014] In one of the embodiments, the glue spreading roller and the glue coating roller are both cylindrical structures, and the axial length of the glue spreading roller is equal to the axial length of the glue coating roller.

[0015] In one of the embodiments, glue blocking plates are provided at both ends of the glue leveling roller; the glue blocking plates are extended from the glue leveling roller to the glue coating roller, and the glue blocking plates are in the shape of a circular straight plate. The glue blocking plates are pressed against the ends of the glue coating roller to block both ends of the glue dropping area.

[0016] In one of the embodiments, the glue injection assembly includes a glue box and a heating element; the heating element is arranged on the outer side wall of the glue box to heat the glue box.

[0017] In one of the embodiments, both side walls of the glue box are provided with glue guiding surfaces; the glue guiding surfaces on both sides are inclined and extend gradually approaching from the glue box to the glue dropping area.

[0018] In one embodiment, the heating element is in the shape of a straight plate, and two heating elements are provided, and the two heating elements are respectively attached to the adhesive conductive surfaces on both sides.

[0019] In one of the embodiments, a glue injection tube is provided at one end of the glue box close to the glue dropping area, and a valve body is provided at one end of the glue injection tube close to the glue dropping area.

[0022] When the glue coating mechanism is started, the glue liquid is in the state of being bonded between the glue coating roller and the glue leveling roller, so a large impact load will be generated between the glue coating roller and the glue leveling roller when the glue coating roller starts to rotate. By rotatably connecting the glue leveling roller with the slide seat, sliding the slide seat on the mounting frame, and elastically pressing the slide seat with the elastic member and the pressure block, the impact load at the time of startup can be unloaded by the sliding seat moving and compressing the elastic member, thereby avoiding damage to the rotating connection position of the glue leveling roller and improving the reliability of the glue coating mechanism.

[0023] By setting glue guiding surfaces on both side walls of the glue box and attaching the heating element to the glue guiding surfaces, compared with the vertical side walls, the inclined glue guiding surfaces can increase the heat conduction area with the heating element, thereby improving the heating effect of the glue liquid, and the inclined glue guiding surfaces can increase the fluidity of the glue liquid injected into the glue dropping area, ensure the glue capacity of the glue dropping area, and thereby improve the bonding effect of the packaging.

The heating element 32 is in the shape of a straight plate, and the heating element 32 is used to heat the glue box 31 to prevent the glue liquid from solidifying and ensure the fluidity of the glue liquid. It can be understood that the heating element 32 is one of a resistance wire, an electric heating film, a semiconductor electric heating sheet or a graphene heating sheet.

[0045] Furthermore, both side walls of the glue box 31 are provided with glue guiding surfaces 311. The glue guiding surfaces 311 are arranged in a straight plate shape on both sides of the glue box 31, and the glue guiding surfaces 311 on both sides are inclined and gradually approached from the glue box 31 to the glue drop area 15, so as to ensure that the glue liquid is better injected into the glue drop area 15.

[0047] In summary, the embodiment of the utility model provides a glue coating mechanism 100, which has the following beneficial effects:

[0048] By arranging the top of the glue coating roller 12 and the glue leveling roller 21 on the side close to the glue injection assembly 30 flush, the glue capacity of the glue drop zone 15 is increased without changing the structure of the glue coating roller 12, so as to ensure that the glue liquid coated on the glue coating roller 12 by the glue leveling roller 21 is more complete during the rotation of the glue coating roller 12 and the glue leveling roller 21, thereby making the glue liquid coated on the package by the glue coating roller 12 more uniform, thereby improving the bonding effect of the package. In addition, arranging the top of the glue coating roller 12 and the glue leveling roller 21 flush can increase the high position of the glue drop zone 15, and then using the downward flow characteristic of the glue liquid, the glue leveling roller 21 can better evenly coat the glue liquid on the glue coating roller 12, further ensuring the bonding effect of the package.

[0049] When the glue coating mechanism 100 is started, the glue is in the state of being bonded between the glue coating roller 12 and the glue leveling roller 21, so a large impact load will be generated between the glue coating roller 12 and the glue leveling roller 21 when the glue coating roller 12 starts to rotate. By rotatably connecting the glue leveling roller 21 with the slide 23, the slide 23 is slid on the mounting frame 22, and the slide 23 is elastically pressed by the elastic member 25 and the pressing block 24, so that the impact load at the start-up can be unloaded by the slide 23 moving and compressing the elastic member 25, thereby avoiding damage to the rotating connection position of the glue leveling roller 21, thereby improving the reliability of the glue coating mechanism 100.

[0050] By setting glue guiding surfaces 311 on both side walls of the glue box 31 and attaching the heating element 32 to the glue guiding surfaces 311, compared with the vertical side walls, the inclined glue guiding surfaces 311 can increase the heat conduction area with the heating element 32, thereby improving the heating effect of the glue liquid, and the inclined glue guiding surfaces 311 can increase the fluidity of the glue liquid injected into the glue dropping area 15, ensure the glue capacity of the glue dropping area 15, and thereby improve the bonding effect of the packaging.

To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0052] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
