Description

TECHNICAL FIELD

[0001] The utility model relates to the auxiliary device of printing machine, concretely is a kind of printing machine preloading paper and automatic paper feeding device. BACKGROUND

[0002] At present, the auxiliary equipment of existing printing machine, especially the printing machine mainly printing 60-140 gram double adhesive paper, generally only preloading paper or only automatic paper feeding, both cannot be used. Among them, preloading paper refers to simultaneously loading paper on prefabricated track during production, and immediately pushing the loaded paper to machine table after the printing of previous edition is finished, so that standby paper feeding equipment is not needed, but manual loading paper is needed. Automatic paper feeding refers to directly pushing neat white material to paper feeding table, and standby paper feeding equipment is not needed, but there is the need for standby paper loading for unneat white material, and dedicated automatic paper cutting machine is needed for paper unloading equipment. Therefore, as disclosed in Chinese patent documents, the authorized announcement number CN212581043U, the authorized announcement date 2021.02.23, the utility model name "a preloading paper device of four-color printing machine"; and as disclosed in Chinese patent documents, the authorized announcement number CN209973789U, the authorized announcement date 2020.01.21, the utility model name "preloading paper assembly, paper feeding mechanism and printing machine"; the above products follow the structure of the preloading paper and paper feeding function of similar products, but the production cost is large, and it is difficult to improve and promote the preloading paper structure of existing printing machine, and the operation of preloading paper and automatic paper feeding is inconvenient. SUMMARY

[0003] To overcome the above shortcomings, the utility model aims to provide a printing machine preloading paper and automatic paper feeding device to the field, which solves the technical problems of poor combination design of preloading paper and automatic paper feeding structure of existing similar products, large production improvement cost and inconvenient operation. The purpose is realized through the following technical scheme.

[0004] A printing machine preloading paper and automatic paper feeding device, the printing machine body side paper feeding area is provided with a paper feeding lifting platform, the preloading paper side of the paper feeding lifting platform is provided with an automatic paper feeding table, the bottom ground of the automatic paper feeding table is provided with a preloading track, and the paper feeding lifting platform moves up and down through the lifting device in the paper feeding area. The ground from the preloading track to the paper feeding lifting platform is provided with a transition track connected and aligned in height, the top of the paper feeding lifting platform is provided with a paper feeding track aligned in height with the transition track, the automatic paper feeding table of the preloading track is pushed into the paper feeding track of the paper feeding lifting platform through the preloading track, the transition track and the paper feeding track in sequence, and the automatic paper feeding table is a paper feeding tray. Through the addition of corresponding tracks and the use of paper feeding tray, the preloading paper and automatic paper feeding of one side of the printing machine body can be met, which is convenient to modify, low in cost, simple to operate, and convenient to adjust and remove.

[0005] The bottom of the automatic paper feeding table is equipped with track wheels that wedge with the pre-installed track, transition track, and paper feeding track. One track wheel of the automatic paper feeding table is equipped with a braking device, or the paper feeding track on one side of the automatic paper feeding table is equipped with a braking block. This facilitates the automatic paper feeding table being pushed into the paper feeding track of the paper feeding lifting platform while simultaneously braking it on the paper feeding track of the paper feeding lifting platform, ensuring its safe operation. In addition to the above structure, the paper feeding lifting platform can also be inclined inwards, which similarly prevents the automatic paper feeding table from slipping backwards after being installed on the paper feeding lifting platform.

[0006] This utility model has a reasonable structural design, low modification cost, simple operation and use, and convenient promotion and application; it is suitable for use as a pre-loading paper and automatic paper feeding device for printing presses, as well as for structural improvements of similar products. Attached Figure Description

[0007] Figure 1 This is an exploded structural diagram of the present invention.

[0008] Figure 2 This is a schematic diagram of the structure of an existing printing press with a pre-loading paper device and an automatic paper feeding device used in combination.

[0009] The attached diagrams are numbered and named as follows: 1. Pre-installed track, 2. Automatic paper feeding table, 3. Paper feeding lifting table, 4. Paper feeding track, 5. Transition track. Implementation

[0010] The structure and use of this utility model will now be further described with reference to the accompanying drawings. Figure 1 , Figure 2 As shown, the device has a paper feeding lifting platform 3 in the paper feeding area on one side of the printing press body, and an automatic paper feeding platform 2 on the pre-loaded paper side of the paper feeding lifting platform. The bottom of the automatic paper feeding platform has a pre-loaded rail 1. The paper feeding lifting platform moves up and down through a lifting device in the paper feeding area. Compared with the prior art, the specific structure of this device is as follows: a transition rail 5 is connected and aligned with the height of the pre-loaded rail to the ground of the paper feeding lifting platform. The top of the paper feeding lifting platform has a paper feeding rail 4 aligned with the height of the transition rail. The automatic paper feeding platform of the pre-loaded rail is pushed into the paper feeding rail of the paper feeding lifting platform in sequence through the pre-loaded rail, the transition rail, and the paper feeding rail. The automatic paper feeding platform is a paper feeding tray.

[0011] Furthermore, the bottom of the aforementioned automatic paper feeding table is provided with track wheels that wedge with the pre-installed track, transition track, and paper feeding track. Additionally, a braking device is provided on one side of the track wheel of the automatic paper feeding table, or a braking block is provided on one side of the paper feeding track of the automatic paper feeding table.

[0012] The device after the modification can use both preloading paper and automatic paper feeding, and the device mainly prints 60-140g double adhesive paper, and the main use is the inner pages of the book; the device has the characteristics of large printing quantity and large workload of the paper feeding end during printing; under normal circumstances, the paper loading time of one paper tray needs 10 minutes, in order to plan the time, the manufacturer provides two schemes when providing accessories, which need to cooperate with preloading paper and automatic paper feeding. Therefore, the device after the modification combines preloading paper and automatic paper feeding, and can directly push the neat white material to the paper feeding table, and the unneat white material can be loaded with paper in advance on the prefabricated track; no matter which paper, the paper loading link can be prepared in advance, and the equipment does not need to wait. The device has the following advantages: 1, only the neat white material needs to be directly pushed to the paper feeding table, and no manual subsequent operation is needed; 2, only the white material needs to be put in advance, and the preloading paper can be realized without manual arrangement.

[0013] The above is only the preferred specific implementation method of the present application, but the protection scope of the present application is not limited to this, any skilled person in the art can make equivalent replacement or change according to the technical scheme and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered in the protection scope of the present application.
