Carton Sealer Tape Wetting Roller for Wet Tape Processing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing carton sealers do not have a wetting mechanism for self-adhesive tapes, limiting their applicability to wet tapes.
Innovation Solution
A tape wetting device is introduced in the carton sealer, comprising a water containing bottle, first and second water tanks, and a wetting roller, with a one-way valve for circulation and a rotating wetting roller that contacts the tape to apply water, controlled by pressing plates.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a self-adhesive tape is used without a wetting mechanism, then the device structure remains simple, but the device cannot process wet tapes
Solution Approach 1:
The wetting device is divided into separate functional modules: water storage tank, pump system, wetting roller, and control unit. This segmentation allows the wetting function to be added independently without redesigning the entire sealing system, thus improving adaptability while managing complexity.
Solution Approach 2:
The wetting roller serves multiple functions: it applies water to the tape adhesive surface, controls the wetting amount through rotation speed, and can be adjusted to accommodate different tape widths. This multi-functionality improves versatility without requiring separate mechanisms for each function.
2Strength
If water is applied to the tape adhesive surface, then the bonding strength is improved for wet tapes, but the conveyance process may be affected
Solution Approach 1:
The pump delivers water in controlled amounts to the wetting roller, which then applies only the necessary amount of water to the adhesive surface area that contacts the tape. This partial action ensures sufficient bonding strength without over-wetting that would slow down conveyance.
Solution Approach 2:
The wetting roller rotates continuously at a controlled speed, maintaining a constant supply of water to the adhesive surface during tape conveyance. This continuous action ensures consistent bonding strength while the rotation speed is synchronized with the tape speed to prevent conveyance disruption.
3Adaptability or versatility
If a wetting mechanism is added to the carton sealer, then the device can process wet tapes, but the device complexity increases
Solution Approach 1:
The wetting function is merged with the existing tape conveyance system by integrating the wetting roller into the path where tapes already pass through the sealer. This combination allows wetting capability to be added without requiring completely separate processing paths or additional complex mechanisms.
Solution Approach 2:
The system includes automatic water level sensing and pump control that adjusts water delivery based on operational conditions. This self-regulating mechanism reduces the need for manual intervention and complex external control systems, thereby limiting the increase in device complexity.

Implementation Method 2
an adhesive surface of the tape transfers and absorbs water attached to a roller surface of the wetting roller
Implementation Method 3
a one-way valve is mounted on a bottleneck of the water containing bottle, the one-way valve is for circulation from the inside to the outside of the water containing bottle
Implementation Method 4

AI summary
The present disclosure provides a tape wetting device in a carton sealer. The device includes a water containing bottle, a first water tank, a second water tank and a wetting roller. The water containing bottle is disposed on the first water tank, the wetting roller is arranged on the second water tank, the first water tank communicates with the second water tank, and the wetting roller is wetted with the water in the second water tank. When a tape passes through the wetting roller, the rotating wetting roller is in contact with the tape, so that an adhesive surface of the tape transfers and absorbs water attached to a roller surface of the wetting roller; and at the same time, the area of contact between the tape and the wetting roller is limited and controlled by pressing plates, so that a wetting effect of the tape is guaranteed.
