Description

BACKGROUND OF THE INVENTION

1. Field of the Invention

This invention relates to an electric cling film cutter, particularly to one able to deliver and cut off cling film automatically and keep the cling film tidy and smooth, facilitating a user to fetch the cling film and safe in use.

2. Description of the Prior Art

A conventional cling film, as shown in Fig. 1, includes a roll of cling film 10 placed in a long casing 11 having its topside provided with an open-able outer cover 12, with a lengthwise opening formed between the outer cover 12 and the casing 11 and having its edge disposed with a serrated cutting member 13. In operating and using, firstly, draw the cling film 10 out of the casing 11 for a preset length to be used. Next, press the outer cover 12 with one hand, and hold the end of the cling film 10 with the other hand and apply a force to draw the cling film 10 reversely to let the cling film 10 cut off by the cutting member 13. However, to cut and tear off the conventional cling film 10, a user can press only one end of the outer cover 12 with one hand but cannot move the same hand along the casing 11 to press other parts of the outer cover 2 at the same time for evenly pressing the outer cover 2; therefore, the cling film 10 can hardly be cut and torn off with smoothness and with a balanced length, likely to make the cling film 10 tangled and deformed and hence resulting in inconvenience in operating and using.
In addition, the conventional cling film 10 has the serrated cutting member 13 disposed outside the casing 11; therefore, when drawing and tearing off the cling film 10, a user is likely to be cut by the sharp teeth of the cutting member 13 in case of operating carelessly.

SUMMARY OF THE INVENTION

The objective of this invention is to offer an electric cling film cutter able to automatically deliver out a cling film to a preset length to be used and electrically cut it off, able to keep the cling film tidy and smooth after it is cut off and safe in use.
The feature of this invention is a delivery wheel 3 assembled in the interior of a base 2 and having its surface fully disposed with lengthwise elongate flutes 31 and plural guide grooves 32 and having one side mounted with a driven rotating wheel 33 engaged with the driving wheel unit 232 of a driving device 23. A cutter 4 is positioned in front of the delivery wheel, composed of a frame plate 41, a motor 42, a belt 43 and a cutter base 44. The frame plate 41 is installed thereon with at least one idle wheel 412, 413 parallel to and leaning on the delivery wheel 3. A stripping guide plate 5 is set beneath the delivery wheel 3 and has its upper end formed with plural protruding parting members 51 respectively aligned to the guide grooves 32 on the delivery wheel 3 for pushing the cling film 10 delivered out to separate from the surface of the delivery wheel 3 and no longer adhere thereon, convenient and safe in use.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

A preferred embodiment of an electric cling film cutter in the present invention, as shown in Figs 2 and 3, includes a base 2, a delivery wheel 3, a cutter 4, and a stripping guide plate 5 as main components combined together.
The base 2 is provided thereon with a positioning frame 21 for fixing a cling film in position, and an auxiliary rotating rod 22 is disposed under the positioning frame 21 to assist guiding and delivering the cling film 10. A driving device 23 is installed in the interior of the base 2 near its lower side, consisting of a motor 231 and a deceleration driving wheel unit 232.
The delivery wheel 3 positioned in the base 2 has its surface fully disposed with transverse elongate flutes 31 and several longitudinal guide grooves 32 and one side assembled with a driven rotating wheel 33 engaged with the driving wheel unit 232 of the driving device 23 in the base 2.
The cutter 4 positioned in front of the delivery wheel 3 is composed of a frame plate 41, a motor 42, a belt 43 and a cutter base 44. The frame plate 41 is assembled on the base 2 and has its opposite sides respectively fixed with a shaft rod 410 extending downward and having its lower side fixed with a belt shaft seat 411. Further, the frame plate 41 is mounted thereon with an upper idle wheel 412 and a lower idle wheel 413 parallel to and leaning on the front side of the delivery wheel 3 to assist guiding and delivering the cling film 10. The motor 42 is installed on the frame plate 41 for correspondingly driving one shaft rod 410 and one belt shaft seat 411 and has its underside provided with an inductor 420. The belt 43 is fitted around the opposite belt shaft seats 411 at the lower side of the frame plate 41. The cutter base 44 secured on the belt 43 has its lower side fixed with a blade 440 having its cutting edge exactly aligned to the elongate flutes 31 in the surface of the delivery wheel 3. The cutter base 44 further has its upper side disposed with a magnetic member 441 to be aligned to the inductor 420 at the underside of the motor 42.
The stripping guide plate 5 is positioned under the delivery wheel 3 and has its upper end formed with plural protruding parting members 51 respectively aligned to the longitudinal guide grooves 32 of the delivery wheel 3 for pushing the cling film delivered out to part from the surface of the delivery wheel 3 and no longer adhere thereon, thus facilitating a user to fetch and use the cling film.
In using, referring to Figs. 2 to 5, firstly, load the cling film 10 in the positioning frame 21 of the base 2 and draw it out to pass over the auxiliary rotating rod 22 and have its end adhering to the surface of the delivery wheel 3 and then start a power source and wait. In operating, a starting button is pressed to start the motor 231 of the starting device 23 to drive the driving wheel unit 232 to rotate and actuate the delivery wheel 3 to operate. Simultaneously the delivery wheel 3 will automatically and continuously draw out the cling film 10 on its surface. At this time, the upper and the lower idle wheel 412 and 413 parallel to and leaning on the front side of the delivery wheel 3 will help to roll and press the cling film 10 to make it tidy and smooth, and the cling film 10 delivered out will be pushed to part from the surface of the delivery wheel 3 by the parting members 51 of the stripping guide plate 5. After the cling film 10 is drawn out to a preset length needed by a user, release the starting button to temporarily stop the motor 231 from driving the delivery wheel 3 to operate, and then start the motor 42 of the cutter 4 to drive the shaft rod 410 and the belt 43 to rotate. Synchronously, the cutter base 44 fixed on the belt 43 will be transversely and linearly moved together with the belt 43 from one end and have the blade 440 cutting off the cling film 10 on the delivery wheel 3. When the cutter base 44 is rotated together with the belt 43 for one round, the inductor 420 at the underside of the motor 42 will induce the magnetic member 441 at the topside of the cutter base 44 and command the motor 42 to stop operating temporarily for stopping the belt 43 and the cutter base 44 from rotating. Thus, through electric cutting, the cling film 10 delivered out can be kept tidy and smooth, letting a user fetch and use the cling film 10 conveniently.
To sum up, the electric cling film cutter of this invention can automatically deliver and cut off the cling film and keep the cling film tidy and smooth, able to let a user to fetch and use the cling film conveniently and safe in use.
While the preferred embodiment of the invention has been described above, it will be recognized and understood that various modifications may be made therein and the appended claims are intended to cover all such modifications that may fall within the spirit and scope of the invention.
