Description

Technical field

The presented utility model relates to hand-held devices for unwinding and cutting pieces of self-adhesive packaging polypropylene tape and paper-based masking tape supplied in rolls.

State of the art

A device is known called a “dispenser” for working with self-adhesive packaging tape with a width of 50-75 mm, in the form of a hand tool with a handle, a roller, a pressure roller, a tension regulator and a cutting blade.

The closest analogue to the described utility model, the STAYER adhesive tape clip, was found in the Internet resource directory http://www.stayer-instrument.ru under article number 1202 in the "adhesive tape tape insulating tape" section, the "tape tape gun" category

On a partial functional basis it is taken as a prototype.

In the prototype, in contrast to the presented solution, there is a housing with a handle in which the roll with the tape rotates. All nodes of the prototype are static, relative to the film. The prototype is intended for use in professional packaging operations of large volume.

The disadvantages of the prototype for mass domestic use and for performing small and one-time packaging operations are its bulkiness, high cost, and poor availability (sale in highly specialized retail outlets). In addition, the prototype is not designed to work with tape on a paper basis.

The author set the task of creating the simplest, most compact, inexpensive and affordable device that facilitates the use of self-adhesive tapes, used in the domestic environment for packaging, painting and other works requiring the use of self-adhesive tape.

The solution was the design in the form of a U-shaped bracket with a blade with teeth, which, when the tape is unwound, moves freely along the roll.

Brief Description of the Drawings

The device consists of the following elements (Figures 1, 2, 3, 5)

Pos. 1. U-shaped bracket.

It is made in the form of a U-shaped element, which has a slot for releasing the film, and a groove for installing the blade. In the side cheeks of the U-shaped bracket there are holes for installing the fixing pin.

Pos. 2. Steel blade with a cutting edge in the form of teeth. Designed for trimming tape. Installed in the groove of the U-shaped bracket.

Pos. 3. Lock pin. Designed to close the cheeks of the U-shaped bracket and to make the position of the device stable on the roll during tape unwinding. It has a persistent head at one end. The other end is made under the cone.

Pos. 4. Cap (shown in section in figure 5) Designed to fix the studs in the device. Installed in the interference fit on the tapered end of the stud.

The figure 4 shows the device in cross section. Utility Model Disclosure

An essential sign for achieving a technical result is a U-shaped bracket with a slot for the exit of the tape. U-shaped bracket moves freely on the roll when manually unwinding the tape in the direction of unwinding.

The second sign is a locking pin that closes the geometry of the structure and holds the U-shaped bracket on the roll when the tape is unwound.

The third feature is a steel blade with a tooth-shaped cutting edge mounted in the groove on the U-shaped bracket for trimming the tape.

The combination of all features provides a technical result, namely :. stable movement of the device along the roll of the tape roll, the possibility of trimming the film and the availability of the tape edge remaining after trimming for the next operation.

Utility Model Implementation

Figure 6. U-shaped bracket is worn on a roll with a pre-stretched portion of the tape threaded into the slot of the U-shaped bracket. A locking pin is inserted into the holes in the side cheeks. A cap is installed on the free end of the pin to prevent the locking pin from falling out. The device is ready to go.

Figure 7. When the tape is unwound, the device moves freely along the roll. Upon reaching the required length of the tape unwinding, the bracket is pressed to the roll with the thumb of the hand, the unwound section of the tape is cut off by touching the stretched tape to the blade with a cutting edge in the form of teeth. The trimmed edge of the tape remains glued to the blade and locks in a taut state, making it easy to pull the tape back and continue the operation. A U-shaped bracket and a locking pin are cast from a polymeric material.

The figure 8 shows a variant of the device for manual winding and cutting of self-adhesive packaging and masking tape in the form of an all-metal stamped structure, consisting of two parts: a U-shaped bracket-blade and a hairpin-retainer.
