Description

Cutter mechanism of liquid packaging machine Technical Field The utility model relates to the technical field of liquid packaging machines, in particular to a cutter mechanism of a liquid packaging machine. Background The liquid packing machine is a special mechanical device for packing liquid products, is widely applied to industries such as food, beverage, daily chemicals, medicines and the like, the working principle is based on different packing modes, such as liquid self-gravity packing under normal pressure is suitable for low-viscosity airless liquid, pressure packing is suitable for gas-containing liquid, the liquid packing is realized by equal pressure or pressure difference, vacuum packing is performed in a bottle negative pressure environment, the liquid packing machine mainly comprises a liquid storage tank, a conveying system, a packing head, a sealer, a labeler, a control system and the like, all parts are operated cooperatively, and processes such as liquid extraction, conveying, packing, sealing, labeling and the like are automatically completed. But the cutter mechanism of the liquid packaging machine is easy to wear after long-time use, and most of the cutters are of an integrated design, so that the problem of inconvenience in disassembly exists, the difficulty and time cost of maintenance and replacement are increased, the worn cutters are also unfavorable to timely repair, the cutting precision is easily reduced, the quality of a cut is easily deteriorated, and the packaging efficiency and the product quality are affected. Disclosure of utility model The utility model aims to solve the problems that in the prior art, a cutter mechanism of a liquid packaging machine is easy to wear after being used for a long time, most of cutters are designed in an integrated mode, and the disassembly is inconvenient, so that the difficulty and time cost of maintenance and replacement are increased, the worn cutters are not easy to repair in time, the cutting precision is easy to drop, the quality of a cut is poor, and the packaging efficiency and the product quality are affected. In order to achieve the above purpose, the present utility model adopts the following technical scheme: the utility model provides a liquid packaging machine cutter mechanism, includes knife rest and maintenance device, one side fixed mounting of knife rest has the cylinder, the actuating lever is fixed to the actuating lever of actuating lever, the surface sliding connection of knife rest has the balladeur train, the actuating lever is kept away from the one end and the balladeur train fixed connection of cylinder, the surface of balladeur train is provided with the cutter, maintenance device sets up in one side of balladeur train, maintenance device is including placing the board, place board and balladeur train fixed connection, the fixed surface of placing the board has the inserted bar, the through-hole has been seted up on the surface of cutter, the inserted bar is inserted with the through-hole on cutter surface, the spout has been seted up on the surface of balladeur train, the inner wall sliding connection of balladeur train surface spout has the baffle, push away from the inner wall sliding connection of a baffle side push channel has the peg, the fixed surface connection of cutter has the fixture block, through setting up maintenance device, realizes that the cutter is quick convenient to change, supports piece, peg, fixture block and fixed spring's cooperation, only needs simple rotation and push-pull baffle, just can easily dismantle and install the cutter, reduces the guarantee to change the spout, and when guaranteeing that the cutter can not become flexible quality can not be guaranteed to cut with the fixed quality, and packing machine stability when guaranteeing that the cutter can not be stable. Preferably, one side fixedly connected with fixed spring of peg, one side and baffle fixed connection of peg are kept away from to fixed spring, through setting up fixed spring, and fixed spring's effect is to provide elasticity to realize the separation of peg and fixture block, when the rotation threaded rod drives to support the piece and keep away from the peg, fixed spring loses the constraint, and the elasticity that its produced can pull the peg, makes the peg break away from the fixture block, thereby creates the condition for follow-up tool removal, has made things convenient for the dismantlement process of cutter. Preferably, the upper surface sliding connection who places the board has to support the piece, the upper surface threaded connection who places the board has the threaded rod, the threaded rod rotates with to be connected, through setting up the threaded rod, when needs change cutter, rotates the threaded rod and drives to support the piece and keep away from the peg, makes fixed spring lose the constraint to can pull the peg and break away from the fixture block, prepare for taking off the cutt
