Abstract

A sealing apparatus for closing the plastic bag comprises a base, a sealing slot inclining inside disposed in one side of the base, a tape reel slot holding an adhesive tape reel in the other side, a guide member adjacent to the sealing slot, and a severing means below the guide member, a fore guide wheel and a back guide wheel connected to the base between the sealing slot and the tape reel slot, and a folding device disposed between the fore guide wheel and the back guide wheel. The folding device in the moving direction of the tape comprises a baffle which disposed upon the inside edge of the adhesive tape and pre-folding the inside edge of the adhesive tape, a slant guide inclining outside and folding back the inside edge of the adhesive tape, and a guide tape block or press roller pressed the folded edge of the tape. The lowest point of the guide tape block or press roller is higher than the lowest of the fore guide wheel. The seal apparatus can fold one side edge of the tape to make two adhesive surfaces of the tape form a narrow margin which does not adhere to each other without affecting the seal of the package. Thus the adhesive tape can be easily peered off the package.

Description

Plastic bag sealing machine

The present invention relates to a sealing machine, and more particularly to a sealing machine for easily removing a tape after sealing a plastic packaging bag. Background technique

The commonly used plastic bag sealing machine is a frame that is connected by a pair of metal L-shaped gantry through fasteners, and is respectively arranged in an inwardly inclined sealing groove and a tape seat groove on both sides of the machine base, and is installed in the sealing groove. There are guiding mechanisms and cutting mechanisms. During work, the pre-bundled packaging bag is placed in the sealing groove and slided in. The tape on the tape seat is bonded to the packaging bag for bundling and sealing, and then the cutting mechanism is used to cut the tape to complete the sealing of the packaging bag. Since the adhesive faces of the tape are completely bonded to each other when the tape is sealed to the package, it is difficult to separate the adhesive faces of the tape when the package is unpacked, which is time consuming and laborious, so it is usually treated with scissors. Cut the bag and remove the packaged object. Summary of the invention

The object of the present invention is to provide a tape which can be firmly adhered to a packaging bag, and can fold the side of the tape and bond the rubber faces on both sides to form a narrow non-sticking narrow side, which is convenient. A plastic bag sealing machine that removes the tape from the package.

The technical solution of the present invention for achieving the above object is: a plastic bag sealing machine, comprising a machine base, a sealing groove which is arranged inwardly inclined on one side of the machine seat, a seat groove on which the tape seat is placed on the other side, and a sealing groove at the sealing groove. a guiding mechanism and a cutting mechanism located at a lower portion of the guiding mechanism, wherein the base is further connected with a front guiding wheel and a rear guiding wheel between the sealing groove and the seat groove, and the base is installed between the front guiding wheel and the rear guiding wheel There is a hemming mechanism, and the hemming mechanism includes a stopper which is disposed along the tape toward the inner side of the tape and which can pre-fold the inner side of the tape, and a beveled guide which is inclined outward to fold the inner side of the tape and The tape guide or the crimper that is flattened by the pre-folding of the tape, and the lowest point of the tape guide or the pressure wheel is higher than the lowest point of the front guide wheel.

The invention adopts the above technical solution, and has the following advantages: the invention adds a hemming mechanism to the machine base, in the process of pulling the tape, firstly, the inner side of the tape is folded by the stopper, and then the tape is folded back by the inclined guide block. During the operation of the tape, the crimping of the tape is pressed by the tape guide or the crimping wheel Flat, so that the tape forms a narrow, non-adhesive narrow side, so when the tape is bonded to the bag, a non-stick narrow side is formed. When the tape needs to be removed, the tape is not sticky. tilt, the force can be easily peeled off the tape, without breaking the bag, convenient operation BRIEF DESCRIPTION _ώ

A plastic bag sealing machine shown in Figs. 1 to 4 includes a sealing groove 3 which is disposed inwardly inclined on one side of the machine base 1, a seated groove 5 on which the tape holder 6 is placed on the other side, and a guide at the sealing groove 3. The mechanism 2 and the cutting mechanism 4 located at the lower portion of the guiding mechanism 2. The base 1 is composed of two interconnected L-shaped gantry. The two sides of the base 1 are respectively provided with an inwardly inclined sealing groove 3 and a seated groove 5, and the upper part of the sealing groove 3 has a guiding bag. The guiding mechanism 2 is composed of a roller 2-1 and a pressure seat 2-2. The pressure seat 2-2 is hinged on the base 1, and the other end of the return spring connected to the base 1 is connected to the pressure seat 2 at one end. 2 Connection, when the bag passes the roller 2-1 and the press seat 2-2, the bag is tightened and smoothly moved down by the rotation of the roller 2-1 and the movement of the press seat 2-3. The cutting mechanism 4 of the present invention is composed of a holder 4-2 and a holder 4-3 which have a cutter 4-1, and the holder 4-2 and the holder 4-3 are respectively hinged to the base 1, and respectively It is connected to a return spring, when the bag through seat ^{^4--2} fulcrum along the hinge, cutting the tape by the cutter 4-1, so that the sealing tape to complete the work. A cutter that cuts the pocket opening may also be provided in the lower portion of the cutting mechanism 4. Referring to Figures 3 and 4, the base 1 of the present invention is also connected with a front guide between the sealing groove 3 and the seat groove 5. The wheel 10 and the rear guide wheel 8, the outer circumference of the rear guide wheel 8 has a tooth shape, preferably the tooth shape on the periphery of the outer circumference is a helical tooth or a vertical tooth, on one side of the rear guide wheel 8, and the rear guide wheel On one side of the 8th, the base 1 is also provided with a limit wheel 9 which is lower than the lowest point of the rear guide wheel 8, so that the tape can be easily pulled out.
