Specific embodiment

The utility model is explained in detail with reference to the accompanying drawing, but it is emphasized that following embodiment Only it is exemplary, rather than in order to limit the scope of the utility model and application.

Please refer to Fig. 1 to Fig. 4, one kind of the utility model cuts film device automatically, including rack 1, is movably arranged on rack 1 On positioning mechanism 2 and the cutter mechanism 3 that is connect with positioning mechanism 2.

Referring to Fig. 1, positioning mechanism 2 includes the first cylinder 21 and the first cylinder that end is rotatably mounted in rack 1 The swing arm 22 of 21 transmission connections.In the utility model first embodiment, the piston rod of the first cylinder 21 and the middle part of swing arm 22 are passed Dynamic connection, and the piston rod of the first cylinder 21 and swing arm 22 are located at the same side.The film device that cuts automatically in first embodiment is used for Film is cut automatically in winder reel change.Referring to fig. 4, in the utility model second embodiment, the piston rod of the first cylinder 21 It is sequentially connected with the middle part of swing arm 22, and the piston rod of the first cylinder 21 and swing arm 22 be not positioned at ipsilateral.In second embodiment The automatic film device that cuts for cutting film in unreeling machine reel change automatically.Positioning mechanism 2 further includes the swing arm being fixed in rack 1 Axis 23, the end of swing arm 22 are movably arranged on arm shaft 23, and the front end of swing arm 22 is connect with pressure roller 24.

Referring to Fig. 1, Fig. 2, cutter mechanism 3 includes the second cylinder 31, the tool arm 32 connecting with the second cylinder 31 and is fixed on The cutter 33 of 32 end of tool arm.Tool arm 32 include rotatably be mounted on pressure roller 24 rotating part 321, from rotating part 321 to The preceding interconnecting piece 322 extended and outward bending is formed.322 rear end of interconnecting piece is connect with the piston rod of the second cylinder 31, even 322 front end of socket part is connected with cutter 33, and cutter 33 includes knife handle 331 and blade 332, before knife handle 331 is fixed on interconnecting piece 322 End.

When work, when the coiled material on work station reaches preset coil diameter, the Scroll on work station is to turning over Turn, at this point, 21 piston rod of the first cylinder extends and swing arm 22 is driven to rotate, 22 lower end of swing arm is rotated around arm shaft 23, swing arm 22 Upper end band dynamic pressure roller 24 rotate together, referring to Fig. 3, then, the piston rod of the second cylinder 31 extends and drives tool arm 32 around pressure Roller 24 turns to operating position B by initial position A, pressure roller 24 by the substrate of the Scroll after overturning with it is spare with double-sided adhesive Reel pressing, meanwhile, cutter 33 rotates around pressure roller 24 and cuts off the substrate around spare reel, after cutting, the second gas The piston rod of cylinder 31 shortens and the rotation of tool arm 32 is driven to reset, and tool arm 32 is separated with dynamic pressure roller 24 with spare reel, meanwhile, the The piston rod of one cylinder 21 shortens and the rotation of swing arm 22 is driven to reset.

The utility model cuts film device automatically, and pressure roller 24 is installed on the front end of swing arm 22,24 activity of cutter 22 and pressure roller Connection is cut in membrane process, and the first cylinder 21 drives swing arm 22 to arrive suitable position, and it is suitable that swing arm 22 is rotated together with dynamic pressure roller 24 Position, at this point, only needing 31 piston rod of the second cylinder to extend and cutter 33 being driven to rotate around pressure roller 24, control mode is simply clever Living, precision is high.

Certainly, those skilled in the art in the art are it should be appreciated that above-described embodiment is intended merely to illustrate this reality With novel, and it is not used as the restriction to the utility model, as long as in the spirit of the utility model, to above-mentioned reality Apply the variation of example, modification will all be fallen in the range of the utility model claims.
