The lining paper processing and boxing process and equipment can be combined to understand, and referring to fig. 1 to 19, the lining paper processing and boxing process comprises the following steps:

a gluing step of placing the inner liner paper 100 with the surface A facing upward and the surface B facing downward and gluing the surface A of the inner liner paper 100;

a reversing step of sucking the lining paper 100 from the surface a of the lining paper 100 and reversing the lining paper 100 so that the surface B faces upward and the surface a faces downward;

a folding step of fixing the lining paper 100 by suction from the B surface of the lining paper 100 and folding the lining paper 100;

and a box packing step of packing the lining paper 100 into the packing box 200.

The lining paper processing and boxing equipment is correspondingly provided with a gluing station 01, a turning station 02, a flanging station 03 and a boxing station 04 which are respectively used for realizing each procedure.

Generally speaking, it is easier to operate to glue on the stock when the stock is in the plane state than being in the viscose on the stock under the three-dimensional state, and prior art selects the processing mode of viscose after the hem, and the interior slip sheet after the hem is three-dimensional shape, and is high to viscose equipment requirement, and equipment cost is high, consequently, is forced to select artifical rubberizing.

According to the invention, by changing the sequence of the folding edge and the gluing, the inner lining paper can be glued in a planar state, and then the glued inner lining paper is folded, so that the automatic production and assembly can be realized by using the existing planar gluing equipment, such as a rolling brush, or a double-faced adhesive tape tearing device (application No. 2020216938677) previously applied by the applicant.

In one embodiment, the gluing process uses a double-sided adhesive tape gluing process or a gun-scraping hot-melt adhesive process. The double-sided adhesive tape is a roll-shaped adhesive tape which is prepared by taking paper, cloth and a plastic film as base materials and then uniformly coating an elastomer type pressure-sensitive adhesive or a resin type pressure-sensitive adhesive on the base materials, and consists of the base materials, an adhesive and release paper (also called release film and silicone oil paper), wherein the release paper of the double-sided adhesive tape needs to be torn when in processing; scrape rifle hot melt adhesive technology and use and scrape gluey rifle, scrape and have the hot melt glue solution in the gluey rifle, the play jiao kou has the tongue piece, scrapes the object of treating the rubberizing with the tongue piece, then tongue piece guide glue solution leave over down one on article and glue the trace the same with the tongue piece width, can reach the effect the same with the double faced adhesive tape: it is suitable for use when fine control of the glue mark width is required.

In one embodiment, the double-sided adhesive bonding process is realized by firstly bonding double-sided adhesive and then tearing off the double-sided adhesive release paper at two stations, or is realized by bonding double-sided adhesive and tearing off the double-sided adhesive release paper at one station. The existing equipment for sticking the double-sided adhesive tape can be adopted to stick the double-sided adhesive tape when passing through two stations, the existing equipment for tearing the double-sided adhesive tape from the type paper can be adopted to operate, and the equipment for sticking the double-sided adhesive tape and tearing the double-sided adhesive tape from the type paper can be adopted to apply the device (application number 2020216938677) for tearing and sticking the double-sided adhesive tape, which is previously applied by the applicant, when passing through one station.

In the invention, the lining paper comprises two meanings, namely the lining paper before forming, namely the lining paper supplied material without the folded edge, and the lining paper after forming, namely the formed lining paper with the folded edge, for the sake of brevity, the invention is not described in a distinguishing way, the lining paper is uniformly described, and the meanings of the lining paper can be understood by a person skilled in the art according to the station where the lining paper is located.

The transfer of interior slip sheet can adopt the conveyer belt, and in the concrete implementation, can also set up interior slip sheet material loading station 05 before viscose station 01 for place interior slip sheet on the conveyer belt one by one, the material loading station can use artifical material loading, also can use current paper material loading attachment, does not do the special restriction.

Referring to fig. 3 to 5:

in one embodiment, be provided with turning device on the upset station, the upset process is realized through turning device, turning device includes:

a turnover mechanism 10 configured to suck the lining paper 100 from the a surface of the lining paper 100, and drive the lining paper 100 to turn over toward the receiving mechanism 20 with the a surface of the lining paper 100 facing the receiving mechanism 20;

and the receiving mechanism 20 is configured to receive the lining paper 100 on the a surface of the lining paper 100 by the turnover mechanism 10 after the turnover mechanism 10 drives the lining paper 100 to turn over, and drive the lining paper 100 to move.

The inner lining paper is pasted in the packaging box, in the pasting process, one surface of the inner lining paper facing the packaging box is the surface A, and the surface of the inner lining paper facing away from the packaging box is the surface B. In order to ensure that the lining paper is firmly attached, the A surface of the lining paper is generally locally glued.

The existing operation flow is that firstly, the A surface of the lining paper faces upwards, the B surface faces downwards, then, the A surface of the lining paper is glued, then, the B surface of the lining paper is adsorbed by the turnover device to drive the lining paper to turn over to the B surface faces upwards, the A surface faces downwards, finally, the turnover device is moved to transfer the lining paper to the next station, and then, the lining paper is pasted in the packaging box. The defect of this method is that the adhesive is adhered to the side A of the inner lining paper, the inner lining paper needs to be sucked from the side B during the adhering process, so that the side A of the inner lining paper can be conveniently adhered in the packing box, and the turnover device is positioned on the side B of the inner lining paper after the turnover device is turned over to cause blockage, so that the turnover device needs to be moved away to suck the inner lining paper from the side B, and the working hours are increased.

The method is different from the prior art, the lining paper is not sucked from the surface B of the lining paper to be turned, the lining paper is partially glued under the horizontal state, and then the material is sucked from the surface A of the lining paper to be turned; after the overturning, the overturning mechanism and the bearing mechanism are mutually abducted, the surface A of the lining paper cannot be interfered to be contacted with the bearing mechanism, and therefore the lining paper can be placed on the bearing mechanism through the surface A. Thus, after overturning, the overturning mechanism still remains on the side of the side A of the lining paper, so that the side B of the lining paper is completely exposed without blocking; the equipment of next station can directly absorb interior slip sheet from the B face of interior slip sheet, has reduced the action, and work efficiency obtains promoting.
