Description

Technical Field

[0001] The utility model relates to the technical field of packaging material processing, in particular to a glue coating roller. 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] During use, the laminating equipment will first apply glue to the package, and then laminate the two packages. The component that applies glue to the package is the glue roller. The glue box will drip the glue onto the glue roller, and the glue roller will then apply the glue to the package by rolling. However, since the glue needs to be kept in a molten state during the coating process, the glue needs to be kept at a relatively high temperature. The existing glue rollers are usually cylindrical in structure, and the thermal conductivity of the glue rollers is high, which leads to good heat dissipation performance of the glue rollers. Therefore, the high-temperature glue coming out of the glue box cools down quickly at the contact position with the glue roller. Long-term use will cause a layer of solidified glue to adhere to the outside of the glue roller. If not handled in time, the attached glue layer will gradually become thicker. Therefore, the glue rollers need to be regularly maintained and cleaned, which wastes glue and affects efficiency, resulting in higher production costs. Utility Model Content

[0004] The technical problems to be solved by the utility model are:

[0005] The glue coating roller has good heat dissipation performance, and the glue will solidify and adhere to the outside of the glue coating roller, which needs to be cleaned regularly, wasting glue and affecting efficiency, making production costs higher.

[0006] In order to solve the above technical problems, the utility model provides a glue coating roller, comprising:

[0007] Central axis;

[0008] An outer roller connected to the central axis, the outer roller is disposed around the outer side of the central axis; the outer roller includes an end plate and a roller plate; the end plate is connected to the central axis, the end plate extends from the outer curved surface of the central axis in a direction away from the central axis, the end plates are disposed on both sides of the roller plate opposite to each other, and the roller plate is disposed around the outer side of the central axis; a cavity is disposed between the roller plate and the central axis, and the end plate covers both ends of the cavity; and

[0009] A rib plate is supported between the central shaft and the roller plate.

[0010] In one embodiment, the rib is in the shape of a straight plate, and the rib extends from the outer curved surface of the central axis toward the roller plate.

[0011] In one of the embodiments, the extension plane where the ribs are located is perpendicular to the extension direction of the central axis.

[0012] In one embodiment, a plurality of ribs are provided, and the ribs are spaced apart along the central axis.

[0013] In one of the embodiments, the rib plate is provided with a connecting hole; the connecting hole is in the shape of a through hole and passes through two sides of the rib plate.

[0014] In one embodiment, a plurality of the communicating holes are provided, and the communicating holes are evenly spaced around the central axis.

[0015] In one of the embodiments, a heating hole is provided on the central axis; the heating hole and the central axis extend in the same direction, and the heating hole is in the form of a through hole that passes through both ends of the central axis.

[0016] In one embodiment, the central shaft is provided in a cylindrical structure, the heating hole is provided in a circular through-hole structure, and the central axis of the central shaft is colinear with the central axis of the heating hole.

[0017] In one embodiment, the end plate is in the shape of a circular straight plate, and the extension plane where the end plate is located is perpendicular to the extension direction of the central axis.

[0018] In one embodiment, the roller plate is provided in a circular cylindrical structure, the central axis is provided on the central axis of the roller plate, and the end of the roller plate is engaged with the outer edge of the end plate.

[0019] Compared with the prior art, the above-mentioned glue coating roller has the following beneficial effects:

[0020] By arranging the end plate to support the roller plate, a cavity is formed between the roller plate and the central axis, thereby reducing the heat transfer efficiency from the roller plate to the central axis. In the process of coating the packaging with glue, the thermal insulation performance of the contact point between the outer side of the roller plate and the glue is improved, preventing the glue from solidifying and adhering to the outer side of the rubber roller, avoiding the waste of glue, and eliminating the need for regular cleaning and maintenance of the rubber roller, thereby reducing production costs.

[0021] By providing support by ribs between the central axis and the roller plate, the bearing capacity of the roller plate is improved, and deformation of the roller plate due to the cavity is avoided, which makes it impossible to evenly apply glue to the packages. By providing a rib structure, the feasibility of the cavity structure is ensured, while the deformation resistance of the roller plate is improved, thereby ensuring the stability of the roller plate in applying glue to the packages.

[0022] By setting connecting holes on the ribs, the cavities separated by the ribs are connected to each other, ensuring uniform temperature distribution at various positions in the cavity, avoiding uneven heat distribution on the roller plate, and thus ensuring the gluing effect of the roller plate.

[0036] See also Figure 1 and Figure 2, is a glue coating roller 100 of an embodiment of the utility model, comprising a central shaft 10, an outer roller 20 and a rib plate 30. The central shaft 10 is used to connect with external equipment so that the glue coating roller 100 is in a rotating state during the glue coating process, and performs glue coating operation on the package in a rolling manner. The outer roller 20 is connected to the central axis 10, and the outer roller 20 is arranged around the outside of the central axis 10; the outer roller 20 includes an end plate 21 and a roller plate 22; the end plate 21 is connected to the central axis 10, and the end plate 21 extends from the outer curved surface of the central axis 10 in the direction away from the central axis 10, and the end plates 21 are relatively arranged on both sides of the roller plate 22, and the roller plate 22 is arranged around the outside of the central axis 10; a cavity 25 is arranged between the roller plate 22 and the central axis 10, and the end plate 21 covers both ends of the cavity 25; the roller plate 22 is used for rolling the gluing operation on the package, reducing the heat transfer effect of the roller plate 22 to the central axis 10, and can reduce the heat loss of the glue on the outside of the roller plate 22, thereby avoiding the glue solidification and adhesion to the outside of the roller plate 22, avoiding the waste of glue, and there is no need to regularly clean and maintain the gluing roller 100, which greatly reduces the production cost. The rib plate 30 is supported between the central axis 10 and the roller plate 22, thereby improving the bearing capacity of the roller plate 22 and avoiding deformation of the roller plate 22 caused by the cavity 25. Deformation of the roller plate 22 may lead to uneven coating of the glue. The roller plate 22 is supported by the rib plate 30 to avoid deformation of the roller plate 22 and ensure the stability of the glue coating of the roller plate 22.

[0037] Furthermore, the central axis 10 is roughly cylindrical in structure, and both ends of the central axis 10 are connected to external equipment. The central axis 10 is the main bearing component of the glue coating roller 100. In this embodiment, a heating hole 15 is provided on the central axis 10. The heating hole 15 is a circular through-hole structure, and the heating hole 15 and the central axis 10 have the same extension direction. The heating hole 15 is a through-hole that passes through both ends of the central axis 10, and the central axis of the central axis 10 is colinear with the central axis of the heating hole 15. The heating hole 15 is used for inserting an external heating component, and the central axis 10 is heated by the heating component, thereby reducing the temperature difference between the central axis 10 and the roller plate 22, and further reducing the heat transfer efficiency from the roller plate 22 to the central axis 10, ensuring the glue temperature, and preventing the glue from solidifying and adhering.

[0038] Furthermore, the end plate 21 is in the shape of a circular straight plate. The end plate 21 is correspondingly arranged at the two ends of the outer roller 20. The extension plane of the end plate 21 is perpendicular to the extension direction of the central axis 10. The end plate 21 is used to mount the roller plate 22 on the outside of the central axis 10, thereby forming a cavity 25. The roller plate 22 is arranged in a circular cylindrical structure. The roller plate 22 is arranged around the outside of the central axis 10. The end of the roller plate 22 is engaged with the outer edge of the end plate 21 to ensure that the cavity 25 is a relatively closed space. In this embodiment, the cavity 25 is arranged in a circular ring between the central axis 10 and the roller plate 22. The central axis 10 is arranged on the central axis of the roller plate 22 to ensure that the distance between the central axis 10 and the roller plate 22 is the same, to ensure uniform heat distribution, and to improve the gluing effect of the roller plate 22 on the package.

[0039] Furthermore, the rib plate 30 is in the shape of a straight plate, and the rib plate 30 extends from the outer curved surface of the central axis 10 toward the roller plate 22.

The rib plate 30 is supported between the central axis 10 and the roller plate 22. In this embodiment, the extension plane where the rib plate 30 is located is perpendicular to the extension direction of the central axis 10, so as to ensure that the pressure on the roller plate 22 is transmitted to the central axis 10 through the rib plate 30 in the radial direction, so as to avoid the pressure generating torque on the rib plate 30 and causing deformation, thereby improving the reliability of the rib plate 30 supporting the roller plate 22. A plurality of rib plates 30 are provided, and each rib plate 30 is arranged at intervals along the central axis 10, so as to improve the supporting effect of the rib plate 30 on the roller plate 22 and improve the bearing capacity of the roller plate 22.

[0040] Furthermore, a connecting hole 35 is provided on the rib plate 30. The connecting hole 35 is in the shape of a through hole, and the connecting hole 35 penetrates both sides of the rib plate 30 to ensure that the spaces on both sides separated by the rib plate 30 are connected, so that the heat distribution of the cavity 25 is uniform, and the gluing effect of the roller plate 22 on the package is improved. In this embodiment, a plurality of connecting holes 35 are provided, and each connecting hole 35 is evenly spaced around the central axis 10. By providing a plurality of connecting holes 35, the heat transfer efficiency between the spaces on both sides separated by the rib plate 30 is improved. By evenly spaced around the central axis 10, the heat transfer uniformity in the cavity 25 is ensured, and the gluing effect of the roller plate 22 on the package is further ensured.

[0042] The roller plate 22 is supported by arranging the end plate 21, and a cavity 25 is formed between the roller plate 22 and the central axis 10, thereby reducing the heat transfer efficiency from the roller plate 22 to the central axis 10.

[0043] By providing support by ribs 30 between the central axis 10 and the roller plate 22, the bearing capacity of the roller plate 22 is improved, and deformation of the roller plate 22 due to the provision of the cavity 25 is avoided, which makes it impossible to evenly apply glue to the package. By providing the ribs 30 structure, the feasibility of the cavity 25 structure is ensured, while the deformation resistance of the roller plate 22 is improved, thereby ensuring the stability of the roller plate 22 in applying glue to the package.

[0044] By providing connecting holes 35 on the ribs 30 , the cavities 25 separated by the ribs 30 are connected to each other, ensuring uniform temperature distribution at various locations in the cavities 25 , avoiding uneven heat distribution on the roller plate 22 , and thus ensuring the gluing effect of the roller plate 22 .
