Therefore, the present invention is an improvement of the prior art, and substantially lies in the connection relationship between hardware. The present invention is described for better illustration of the function and method for better understanding of the present invention.

Embodiments of the present invention will be described in detail below with reference to the accompanying drawings. The following examples are only for illustrating the technical solutions of the present invention more clearly, and therefore are only examples, and the protection scope of the present invention is not limited thereby.

It is to be noted that unless otherwise specified, technical or scientific terms used herein shall have the ordinary meaning as understood by those skilled in the art to which the present invention belongs.

As shown in fig. 1, the EVA foam adhesive cutting device provided in this embodiment includes a handheld housing 100 and a foam cutting assembly; EVA bubble celloidin tailors the device and can be used for tailorring bubble cotton adhesive tape, improves the efficiency of tailorring of bubble cotton adhesive tape, avoids the sticky tape to tailor through manual and leads to the sticky tape damaged. In order to realize handheld tailorring, this embodiment is equipped with the cut-off mouth that supplies the cotton sticky tape of bubble to pass at handheld shell 100 front end, and handheld shell 100 rear end is equipped with the sticky tape installation department that rotates installation bubble cotton sticky tape body, the cotton subassembly of cutting off of bubble includes fixed blade 200 and movable blade 300 that the cutting edge was arranged relatively, fixed blade 200 is fixed in the cut-off mouth roof, movable blade 300 both ends are through pivot 400 and cut-off mouth lateral wall normal running fit, the cover has reset torsion spring on the pivot 400, makes movable blade 300 keeps away from with fixed blade 200 under reset torsion spring's torsion effect mutually, movable blade 300 one end is connected and extends to handheld shell 100 rear end and cuts out handle 500, rotates cut out handle 500 can make the cutting edge of movable blade 300 be close to the cutting edge of fixed blade. When the EVA foam adhesive cutting device is used, the foam adhesive tape is rotatably mounted through the adhesive tape mounting part of the handheld shell 100 and can rotate so as to tear the adhesive tape off; the cotton sticky tape of accessible bubble cuts off the subassembly and cuts off the cotton sticky tape of bubble after passing the fracture, the cotton subassembly setting of cutting off of bubble can cut off the sticky tape fast when cutting the fixed blade 200 and the movable blade 300 relative motion of fracture, the handle 500 of cutting off with movable blade 300 fixed connection can press down the rotation and then drive the activity and rotate, when the cutting edge of fixed blade 200 and the cutting edge of movable blade 300 were close to each other, can cut off the cotton sticky tape of bubble, because be equipped with the reset torsion spring on the fixed blade, the reset torsion spring receives can produce the elasticity that resets after the torsion, but movable blade automatic re-setting after the completion of tailorring, so that cut off the cotton sticky tape.

As shown in fig. 1, since the tape mounting portion is spaced from the cutting opening, in order to avoid the tape from bending when being conveyed to the cutting opening, the cutting opening is provided with a rotatably arranged supporting roller 600, and two ends of the supporting roller 600 are rotatably matched with the inner side wall of the cutting opening. In addition, a pair of transition rollers 700 which are arranged oppositely is arranged between the corresponding adhesive tape mounting part and the supporting roller of the handheld shell 100, and the transition rollers 700 are rotatably arranged on the inner side surface of the handheld shell 100. Like this, backing roll 600 and transition roller 700 can play the effect of supporting transition bubble cotton sticky tape, because the bonding face of bubble cotton sticky tape has very strong viscidity, should avoid the sticky tape to bond on backing roll 600 and transition roller 700 should the outer peripheral face, and this embodiment is equipped with from type smooth layer on backing roll and transition roller 700 surface. From smooth layer of type has the smooth difficult characteristics that bonds in surface, can avoid the cotton sticky tape of bubble to bond on the outer peripheral face of backing roll 600 and transition roller 700.

In order to rotate the installation foam adhesive tape, the adhesive tape installation part provided by the embodiment comprises an adhesive tape installation plate 120 arranged on one side of the rear end of the handheld shell 100, an installation roller 800 is arranged on the inner side surface of the adhesive tape installation plate 120, and the foam adhesive tape body is rotatably sleeved on the installation roller 800. The tape mounting plate 120 extends towards the rear end of the handheld housing 100 to form a space for accommodating the foam tape, so that the foam tape body can be rotatably sleeved on the mounting roller 800, and a user can conveniently adjust the cutting length of the tape.

In order to prevent the foam tape body from falling off from the installation roller 800, the edge of the end of the installation roller 800 is provided with an elastic limit rib 810. The limiting convex ridge 810 can prevent the foam adhesive tape body from falling off, and the limiting convex ridge 810 with elasticity is convenient for a user to install the adhesive tape on the installation roller 800.

In order to facilitate a user to hold the handheld housing 100, in the present embodiment, a holding portion 110 extending upward from the installation roller 800 is further disposed at the rear end of the handheld housing 100, the surface of the holding portion 110 is provided with anti-slip patterns, and the cutting handle 500 is obliquely arranged to extend upward from the holding portion 110. The holding portion 110 can facilitate the user to hold the whole device, the anti-slip lines can prevent the holding shell 100 from falling off, and the cutting handle 500 extending to the holding portion 110 facilitates the user to press and rotate the cutting handle 500 to rotate the movable blade 300. In order to prevent the cutting handle 500 from rotating too much, the present embodiment has a limiting portion 900 on the outer side of the hand-held housing 100 and below the cutting handle 500. When the cutting handle 500 rotates to the lowest position, the cutting handle 500 can be limited by the limiting part 900, and further the cutting handle 500 is prevented from rotating and transiting.

In the specification of the present invention, a large number of specific details are explained. It is understood, however, that embodiments of the invention may be practiced without these specific details. In some instances, well-known methods, systems, and techniques have not been shown in detail in order not to obscure an understanding of this description.
