Description

[Technical field]

[0001] The utility model relates to a paper feeding technology of an inkjet printer, in particular to a paper pressing device for the inkjet printer. [Background technology]

[0002] The inkjet printer is a device that uses a non-contact method to mark products. Among the various types of inkjet printers, the most commonly used is the sheet-fed inkjet printer. The existing sheet-fed inkjet printer is composed of a paper feeding device, a conveyor belt, a spray terminal and a stacking and collecting device. When the sheet-fed inkjet printer is working, the paper to be coded is passed to the conveyor belt individually through the paper feeding device, and then the spray terminal installed above the paper feeding belt prints various required variable information on the surface of each packaging cardboard, and the stacking and collecting device stacks and collects the paper in turn to complete the coding process of the packaging cardboard.

[0003] In the existing paper feeding devices, paper feeders are divided into friction paper feeders and pneumatic paper feeders according to the method of separating paper. The friction type automatic paper feeder separates paper from the paper pile by the action of friction. The existing high-speed printing machine or inkjet printer adopts pneumatic paper feeding device. The pneumatic automatic paper feeder separates paper from the paper pile by blowing and suction and delivers it to the host for printing or inkjet printing.

[0004] However, in the existing single-sheet inkjet printer, since the paper feeding device sucks up the stacked packaging papers one by one and then sends them to the conveyor belt, and the packaging paperboards in the multi-layer stack are in contact with each other for a long time and are easy to stick to each other, when the paper feeding device sucks up a single packaging paper, it is inevitable that two packaging paperboards stuck together will be sucked up and sent to the conveyor belt at the same time, thus causing the production line to be shut down for maintenance, seriously affecting production efficiency. [Contents of the utility model]

[0005] The utility model provides a paper pressing device for a printer, which effectively prevents a plurality of packaging papers from overlapping when sucking them, can effectively stabilize paper supply, and improves production efficiency.

[0006] The technical solution adopted by the utility model to solve its technical problems is:

[0007] A paper pressing device for an inkjet printer, used for automatically separating the topmost paper in a paper pile from the next layer of paper, comprising a production line frame, an automatic paper pile lifting platform and a vacuum paper suction assembly, wherein the automatic paper pile lifting platform is used for automatically lifting and feeding the stacked packaging paper, and the vacuum paper suction assembly is used for sucking the paper lifted and fed by the automatic paper pile lifting platform;

[0008] The top side of the production line frame is provided with a crossbeam for transferring the paper on the automatic paper stacking lifting platform to the subsequent conveying line, and the automatic paper stacking lifting platform is installed at the middle and lower part of the paper stacking inlet of the production line frame;

[0009] A vertical cylinder is installed in the middle of the crossbeam for the vacuum paper suction assembly to suck the paper after vertical linear feeding and moving up and down;

[0010] Both sides of the production line frame are respectively provided with lateral movement cylinders for pushing the crossbeam and the vacuum paper suction assembly thereon to feed and move the paper forward and backward in a straight line;

[0011] The crossbeam corresponding to the top side of the stacked packaging paper on the automatic paper stacking lifting platform is also equipped with multiple elastic paper separation components located at the top front edge of the packaging paper, which are used to elastically press the lower paper when the vacuum paper suction component absorbs the top paper to prevent mutual adhesion.

[0012] Preferably, the elastic paper separation assembly includes a fixed seat, a suspension slide rod, a self-tensioning spring and a Z-shaped spring piece. The suspension slide rod is suspended on the beam through the fixed seat, the self-tensioning spring is sleeved on the suspension slide rod, and the Z-shaped spring piece is in contact with the lower end of the self-tensioning spring through a locking buckle and is slidably fixed to the end of the suspension slide rod under the elastic tension of the self-tensioning spring.

[0013] Preferably, the front end of the Z-shaped spring piece is a steel tongue piece that is convenient for elastically avoiding the topmost paper of the stacked packaging paper and elastically pressing and separating the lower paper during the downward movement.

[0014] Preferably, both sides of the production line frame on the top side of the automatic paper stacking lifting platform are also provided with blowing nozzles for simultaneously blowing air to both sides of the topmost side of the stacked packaging paperboard through air pipes to prevent the lower packaging paper from sticking to the topmost packaging paper.

[0015] The beneficial effects of the utility model are:

[0016] The utility model aims to solve the problems in the existing production process that when the wrapping paper is relatively thin and relatively large in size, the paper is not smoothly fed and often jams and blocks the paper, affecting production due to the adhesion between the papers. When the vacuum paper suction component absorbs the top paper, multiple elastic paper separation components located at the top front edge of the wrapping paper elastically contact and press the lower paper to assist in paper separation to prevent the papers from sticking to each other. The utility model is suitable for sucking up papers of various sizes, thicknesses and thins, preventing the wrapping paper from sticking to each other, and facilitating paper separation. It can effectively avoid carrying out multiple sheets of excess wrapping paper in one grabbing, and prevent the excess wrapping paper from overlapping and entering the inkjet printer to cause incomplete printing or paper jams, thereby greatly improving production efficiency.
