Description

Technical Field

[0001] The utility model relates to the technical field of glue storage barrels, in particular to a constant-temperature glue storage barrel for a corrugated board production line. Background Art

[0002] Corrugated cardboard is a multi-layer adhesive body, which is made of at least one layer of corrugated paper and a layer of boxboard. It has good elasticity and extensibility. It is mainly used to make cartons and cardboard sandwich machines as a guarantee material for fragile items. In the corrugated cardboard production line, constant temperature glue storage barrels are used. The constant temperature glue storage barrels are used to heat the glue at a constant temperature for bonding corrugated paper.

[0003] To ensure the stability of glue storage barrels during use, the prior art has made numerous improvements to constant-temperature glue storage barrels for corrugated cardboard production lines. For example, patent publication number CN219965438U discloses a constant-temperature glue storage barrel for corrugated cardboard production lines, comprising an inner barrel and a turret. The outer barrel is fixedly mounted to the outer wall of the inner barrel, forming a cavity between the inner and outer barrels. A hot air flow generating assembly is fixedly mounted to the outer wall of the outer barrel, and a conduction assembly is provided at the output end of the hot air flow generating assembly for supplying hot air between the inner barrel and the cavity. A cover plate and a base are fixedly mounted on either side of the vertical end of the inner barrel, respectively. A servo motor is fixedly mounted on the inner wall of the base, and a drive assembly is provided at the output end of the servo motor for driving the turret. This patent reduces heat exchange between the colloid and the outside world and allows for rapid colloid reheating, avoiding the large-scale discharge of insufficiently active colloid due to a long colloid reheating period, thereby ensuring the stability of the constant-temperature glue storage barrel for corrugated cardboard production lines.

[0004] The above patents have obvious beneficial effects, but still have the following deficiencies in actual operation:

[0005] In the above-mentioned comparative document, a hot air flow is introduced into the inner barrel, and the glue is stirred by a rotating rotating rack, thereby achieving the effect of constant temperature of the glue storage barrel. However, in reality, the colloid is viscous. After the hot air flow enters the glue storage barrel, the colloid in the middle position of the barrel and the colloid at the edge position will be heated unevenly, and the efficiency of the rotating rack in stirring the colloid is low, and the phenomenon of uneven heating of the colloid will still exist. Therefore, this field urgently needs to make improvements to the constant temperature glue storage barrel for corrugated cardboard production lines, so as to solve the defects of the existing technology. Utility Model Content

[0006] In view of the deficiencies in the prior art, the utility model provides a constant-temperature glue storage barrel for a corrugated board production line, which improves the efficiency of stirring the colloid and reduces the uneven heating of the colloid.

[0015] 1. In the present invention, the heating device is used to heat the glue storage barrel.
