Detailed Description

The present invention will be further described with reference to the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and can implement the present invention, but the embodiments are not limited to the present invention.

Referring to fig. 1, for an embodiment of the present invention, including support 1, the gyro wheel 2 of symmetry sets up in the inside of support 1, and both ends are passed through the bearing and are installed on support 1, install motor 9 on support 1, and through the gear train with the wheel 2 on the tooth meshing be connected, motor 9 drive gear group is rotatory, and then realizes that motor 9 drives gyro wheel 2 and rotates. The sealing machine 3 is arranged below the roller 2, and the driving mechanism 4 is arranged on the bracket 1 and used for driving the sealing machine 3 to open and close; a stroke rail 5 is installed at the bottom of the support 1, a cutting blade 6 is disposed on the stroke rail 5, and the cutting blade 6 is disposed below the capper 3. When the packaging bags need to be subjected to plastic packaging and cutting, the packaging bags are placed between the rollers 2, and the rollers 2 are driven by the motor 9 to rotate, so that the packaging bags are conveyed. The packaging bag is conveyed to the lower part from the upper part of the roller 2, after a certain distance is conveyed, the motor 9 stops working, the driving mechanism 4 controls the sealing machine 3 to be closed, the packaging bag is sealed in a plastic mode, then the cutting knife 6 moves on the stroke track 5, and the lower end of the plastic seal is cut. And then, continuously conveying the package, carrying out plastic package on the package bag by using a sealing machine 3, and then cutting the lower end of the plastic package by using a cutting knife 6. Namely, the lower end of the small packing bag is plastically sealed, and the cutting knife 6 opens the upper part of the small packing bag, thereby completing the division of the large packing bag into the packing bags with the specified size one by one. The speed of plastic package and cutting of the packaging bag is improved.

As shown in fig. 3, a fixing plate 10 is installed below the roller 2 on the bracket 1, a plurality of guide strips 8 are arranged on the fixing plate 10 at intervals, a plurality of grooves 7 are arranged on the roller 2 at intervals, and the guide strips 8 extend into the upper side of the roller 2 through the grooves 7. When the packaging bag is conveyed, the packaging bag is clamped between the two rollers 2, and the packaging bag is conveyed through the rotation of the rollers 2. The two side surfaces of the packaging bag can be pressed and guided through the symmetrical guide strips 8, so that the packaging bag can be stably conveyed.

In this embodiment, in order to avoid damage to the surface of the packaging bag, the guide strip 8 is made of a rubber material.

As shown in fig. 4 and 5, the driving mechanism 4 includes symmetrically disposed rotating rods 41, two ends of the rotating rods 41 are rotatably connected with the support 1 through bearings, a connecting arm 42 is disposed on the rotating rod 41, and a bottom end of the connecting arm 42 is fixedly connected with the sealing machine 3; the symmetrical rotating rods 41 are respectively provided with a first connecting rod 43 and a second connecting rod 44 in a connected mode, the first connecting rod 43 and the second connecting rod 44 are connected through a third connecting rod 45, two ends of the third connecting rod 45 are respectively hinged with the bottom end of the first connecting rod 43 and the upper end of the second connecting rod 44, the first connecting rod 43 is driven through an air cylinder 46, and the first connecting rod 43 is hinged with a piston rod of the air cylinder 46. The air cylinder 46 drives the upper end of the first link 43 to move outwards, so that the lower end of the first link 43 moves inwards, and since the first link 43 and the second link 44 are hinged by the third link 45, when the lower end of the first link 43 moves inwards, the lower end of the second link 44 moves inwards, so that the rotating rods 41 can be driven to rotate respectively, and the sealing machine 3 connected to the connecting arm 42 is closed. Similarly, when the cylinder 46 drives the upper end of the first link 43 to move inward, the opening of the capper 3 can be realized.

As shown in fig. 6, the cutting blade 6 includes a mounting plate 61 slidably connected to the travel rail 5, and a cutting blade 62 is provided on the mounting plate 61, and both sides of the cutting blade 62 are cutting edges. Since the cutting blade 6 moves back and forth on the travel rail 5 and both sides of the cutter 62 are cutting edges, the packaging bag can be cut regardless of the direction in which the cutter 62 moves. After the cutting is finished, the cutter 62 does not need to return to the initial state, so that the cutting time is greatly shortened, and the cutting efficiency is improved.

During actual work, the wrapping bag presss from both sides between gyro wheel 2, and gyro wheel 2 is rotatory, realizes the transport to the wrapping bag. The air cylinder 46 drives the upper end of the first link 43 to move inward, so that the capper 3 is opened. After the packaging bag is conveyed to the lower portion of the roller 2 for a certain distance, the roller 2 stops rotating, the air cylinder 46 drives the upper end of the first connecting rod 43 to move outwards, so that the sealing machine 3 is closed to carry out plastic sealing on the packaging bag, the cutting knife 6 moves on the travel track 5 to cut the lower portion of the plastic sealing, and then the roller 2 continues rotating, so that the packaging bag is conveyed for a specified distance. The steps are repeated, plastic package cutting can be continuously carried out, and then the large packaging bag is divided into packaging bags with the specified size. Realize the automation through the machine, greatly improved the efficiency of cutting the wrapping bag plastic envelope.
