Description

Technical Field

[0001] The utility model relates to the technical field of plastic packaging bag slitting, in particular to a slitting mechanism for plastic packaging products. Background Art

[0002] Plastic packaging refers to packaging made of plastic. Plastic is primarily made of synthetic or natural polymer resins. By adding various additives, it becomes ductile under certain temperatures and pressures, and its shape stabilizes upon cooling. After the plastic film is formed into a semi-finished plastic box, the semi-finished box needs to be cut from the film and reshaped for subsequent processing.

[0003] When the existing slitting and shaping device is used, it is usually necessary to manually adjust the position of the plastic packaging before slitting, and the transmission and slitting of the plastic packaging cannot be well coordinated. Utility Model Content

[0007] The slitting assembly includes a slitting knife and a fixing rod. The slitting knife is arranged at a position close to the main bracket. The fixing rod is fixedly arranged at one end of the slitting knife and is slidably arranged on the main bracket.

[0008] As a further limitation of the present technical solution, the conveying mechanism includes a driving motor and two groups of mutually symmetrical rotating parts, the driving motor is fixedly set on the main bracket, the rotating parts include a first bevel gear, a second bevel gear, a rotating roller and an L-shaped frame, the L-shaped frame is fixedly set on the main bracket, the first bevel gear and the second bevel gear are both rotatably set on the L-shaped frame, the first bevel gear engages with the second bevel gear, the rotating roller is coaxially fixed on the second bevel gear, and the output shaft of the driving motor is coaxially fixedly connected to the two first bevel gears.

[0009] As a further limitation of the present technical solution, the transmission assembly includes a third bevel gear, which is meshed with one of the first bevel gears. The third bevel gear is rotatably set on the main bracket, and the crank is fixedly set at the end of the third bevel gear. A sliding groove is provided on the fixed rod, and the crank is slidably set in the sliding groove.

[0010] As a further limitation of the present technical solution, a mounting plate is provided on the main bracket, and a plurality of mounting holes are opened on the mounting plate.

[0011] As a further limitation of the present technical solution, the main bracket is provided with a ridge cooperating with the slitting knife at a position corresponding to the slitting knife.

[0012] Compared with the prior art, the advantages and positive effects of the present invention are:

[0013] A transmission mechanism is set up, and the driving motor is started. The output shaft of the driving motor drives the two first bevel gears to rotate. The rotation of the first bevel gear drives the second bevel gear to rotate. The second bevel gear drives the rotating roller to rotate. The two rotating rollers rotate in opposite directions to better transmit the plastic packaging.

[0014] The rotation of the first bevel gear also drives the third bevel gear to rotate. The rotation of the third bevel gear drives the crank to rotate. The crank slides in the slide groove of the fixed rod and drives the fixed rod and the slitting knife to move up and down on the main bracket. The slitting knife contacts the plastic packaging on the main bracket and cuts the plastic packaging.

[0015] The transmission and slitting of plastic packaging can be carried out simultaneously, and the two are coordinated with each other through the transmission component, thereby improving the slitting effect and saving the driving source. BRIEF DESCRIPTION OF THE DRAWINGS
