Description

Technical Field

[0001] The utility model relates to the technical field of paper feeding of printing machines, in particular to a paper feeding wheel adjusting device of a printing machine. Background Art

[0002] In the processing of corrugated cardboard, the corrugated paper needs to be transported for printing, die-cutting, slotting and other processing. When the corrugated paper is transported, it is mainly completed by rolling the two upper and lower opposite paper feed shafts against each other. Usually, the main structure of the paper feed shaft includes a paper feed roller, a paper feed wheel and a motor driving the paper feed roller to rotate. The motor drives the paper feed roller to drive the paper feed wheel to rotate, so that the two opposite paper feed wheels roll against each other to complete the transportation of the corrugated cardboard.

[0003] Since the size of corrugated cardboard is set according to production requirements during the processing, corrugated cardboard of different sizes is often transported. At this time, in order to transport the corrugated cardboard more accurately, the position of the paper feed wheel on the paper feed roller needs to be adjusted so that the cardboard can be accurately transported. In the existing equipment, during the paper feed wheel transportation process, the production equipment needs to be stopped and the position of the paper feed wheel needs to be adjusted manually. The adjustment process is relatively cumbersome, and the paper feed wheel needs to be removed after the shutdown before adjustment, which seriously affects the production efficiency. In addition, the adjustment method is also relatively troublesome, and the labor intensity of the operator is relatively high.

[0004] Therefore, there is an urgent need for an adjusting device for the paper feeding wheel of a printing press. Utility Model Content

[0028] In order to make the technical problems, technical solutions and beneficial effects solved by the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0029] It should be noted that in the embodiments of the present utility model, all directional indications (such as up, down, left, right, front, back, etc.) are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0030] In addition, the descriptions of “first”, “second”, etc. in the embodiments of the present invention are only used for descriptive purposes and cannot be understood as indicating or suggesting their relative importance or implicitly indicating the number of the indicated technical features.

[0031] The embodiment of the utility model provides an adjustment device for the paper feed wheel 102 of a printing press, which can automatically adjust the paper feed wheel 102 without stopping the machine and only pausing it, and can accurately know the specific stroke distance of the paper feed wheel 102 adjusted. During the adjustment process, it can not affect the normal production and processing of the equipment, and at the same time, it can avoid the operator from performing heavy physical labor.

[0032] like Figures 1-3 As shown, an adjusting device for a paper feed wheel 102 of a printing press provided by an embodiment of the utility model can adjust the paper feed wheel 102 along the axial direction of a paper feed roller 101. The device comprises a guide rod 110, a toggle mechanism 200 and a driving mechanism, wherein the guide rod 110 and the paper feed roller 101 are arranged parallel to each other; the toggle mechanism 200 is slidably connected to the guide rod 110 along the axial direction of the guide rod 110, and is arranged corresponding to the paper feed wheel 102; the driving mechanism is transmission-connected to the toggle mechanism 200, so as to drive the toggle mechanism 200 to reciprocate along the axial direction of the guide rod 110, thereby pushing the paper feed wheel 102 to move along the axial direction of the paper feed roller 101, and the driving mechanism is also electrically connected to a stroke acquisition device 301, and the stroke acquisition device 301 is used to acquire displacement data of the toggle mechanism 200 along the axial direction of the guide rod 110.

[0033] As Figure 1 shown, both ends of the paper feed roller 101 are rotatably connected to the frame plate 100 and are driven by a drive system The system drives the paper feed roller 101 to rotate, and the paper feed wheel 102 is slidably connected to the paper feed roller 101 along the axial direction of the paper feed roller 101. It can be imagined that in order to be able to transport the cardboard, a locking structure must be provided on the paper feed wheel 102 to prevent the paper feed wheel 102 from moving during the process of transporting the corrugated cardboard, thereby affecting the transportation of the cardboard. The specific structure of the locking structure can adopt any one of the existing technologies, which is not limited or elaborated here. It can be understood that the paper feed rollers 101 should be two opposite to each other. In this embodiment, for the convenience of observation, only one is drawn in the accompanying drawings as a specific description of the structure.

[0034] In the process of conveying the corrugated cardboard, the cardboard is placed between two mutually opposed paper feeding rollers 101, and the paper feeding wheels 102 roll each other to convey the cardboard forward. When it is necessary to convey cardboards of different sizes, it is necessary to adjust the relative position of the paper feeding wheel 102 on the paper feeding roller 101 to meet the conveying of cardboards of different sizes. In the technical solution provided in this embodiment, it is only necessary to drive the transmission mechanism connected to the toggle mechanism 200 along the direction of the guide rod 110 when the paper feeder is partially paused, so that the toggle mechanism 200 toggle the paper feeding wheel 102, thereby completing the toggle of the paper feeding wheel 10 2, at the same time, since the travel collecting device 301 is arranged on the driving mechanism, the driving travel data of the driving mechanism on the toggle mechanism 200 can be collected. Similarly, this data is also the travel of the paper feeding wheel 102 adjusted on the paper feeding roller 101, so that it can be accurately adjusted, and can be more suitable for conveying cardboards of different sizes, and has stronger adaptability to cardboards of different sizes. More importantly, in the process of adjusting the paper feeding wheel 102, there is no need to shut down the entire equipment, nor is there any need to dismantle the frame plate 100, which can reduce the impact on production and will not increase the labor intensity of the operator.

[0035] In this embodiment, if Figure 2 As shown, the toggle mechanism 200 includes: a base 201 and a toggle seat 210, the base 201 is slidably connected to the guide rod 110; the toggle seat 210 is fixedly connected to the base 201, and two toggle arms 211 facing each other are formed on the toggle seat 210, and a space for accommodating the paper feed wheel 102 is defined between the two toggle arms 211. In addition, a wear-resistant sheet 212 is detachably connected to the surface of the toggle arm 211 facing the paper feed wheel 102. When the driving mechanism drives the toggle mechanism 200 to move, the wear-resistant sheet 212 contacts the side wall of the paper feed wheel 102 and pushes the paper feed wheel 102 to move along the axis direction of the paper feed roller 101. Two toggle arms 211 are provided through the toggle seat 210, and the two toggle arms 211 are respectively located on both sides of the paper feed wheel 102. When the driving mechanism drives the toggle mechanism 200 to move, the wear-resistant sheet 212 and the paper feed wheel 102 contact each other, thereby pushing the paper feed wheel 102 to reciprocate along the axial direction of the paper feed roller 101, thereby completing the position adjustment of the paper feed wheel 102.

[0036] In this embodiment, if Figures 1-2The figure shows a specific example of the structure of the driving mechanism, which includes a driving motor 304, a screw rod 302 and a transmission block 303, wherein the screw rod 302 is arranged in parallel with the guide rod 110; the transmission block 303 is threadedly connected to the screw rod 302, and reciprocates along the axis direction of the screw rod 302 as the screw rod 302 rotates axially, and the transmission block 303 is fixedly connected to the toggle seat 210; the driving motor 304 is transmission-connected to the screw rod 302 to drive the screw rod 302 to rotate around the axis.

[0037] In this embodiment, the driving motor 304 is connected to the screw rod 302 through a conveyor belt, so that the screw rod 302 can be driven to rotate along the axis, and then the transmission block 303 is driven to move along the axis direction of the screw rod 302, and the toggle mechanism 200 is driven in turn. When the driving motor 304 is switched forward and reverse, the conveying direction of the toggle mechanism 200 can be changed, and then the adjustment direction of the paper feeding wheel 102 can be changed to meet the conveying action of cardboards of different sizes.

[0038] The travel acquisition device 301 is an encoder, and the encoder is in transmission connection with the screw rod 302 to detect the angular displacement data of the screw rod 302. The encoder detects the angular displacement data of the screw rod 302, so that the travel of the transmission block 303 can be calculated, and then the distance data of the paper feeding wheel 102 being adjusted can be known, so that the adjustment accuracy of the paper feeding wheel 102 can be improved, and the accuracy of paper feeding can be improved.

[0039] In this embodiment, two paper feeding wheels 102 are arranged on one paper feeding roller 101, so that the paperboard can be conveyed under the conveyance of the two paper feeding wheels 102, and the paperboard is prevented from being deviated during conveyance. In order to adjust the two paper feeding wheels 102 respectively, as shown in FIG. Figures 1-3 As shown, the utility model makes the following configuration: the guide rod 110 includes two coaxially arranged ones, and an intermediate seat 120 for fixedly connecting the two guide rods 110 is arranged between the two guide rods 110, the intermediate seat 120 includes two intermediate plates 121 respectively fixedly connected to the guide rods 110, and a connecting beam 122 is fixedly connected between the two intermediate plates 121, and the toggle mechanism 200 is provided with two sliding connections respectively on the guide rods 110. Two driving mechanisms are mutually adapted to the guide rods 110, and are respectively connected to the toggle mechanism 200 in transmission, so as to respectively drive the toggle mechanism 200 to move along the guide rods 110, and one end of the screw rods 302 on the two driving mechanisms is respectively rotatably connected to the intermediate plates 121.

[0040] Through the above structure, one of the paper feeding wheels 102 can be adjusted separately, and the position of the other paper feeding wheel 102 will not be affected during the adjustment process, especially when one of the toggle mechanisms 200 or the driving mechanism fails and needs to be repaired, the adjustment of the other paper feeding wheel 102 will not be affected. At the same time, the travel acquisition device 301 is fixedly mounted on the middle plate 121 and is in transmission connection with the corresponding screw rod 302.

[0041] By means of the printing press paper feed wheel 102 adjustment device provided in this embodiment, the paper feed wheel 102 can be adjusted in time without stopping the machine, and the normal operation of the equipment will not be affected during the adjustment process. At the same time, the adjustment method of the adjustment device is relatively simple, and it can be completely controlled by the control system on the equipment, the labor intensity of the operator is greatly reduced, and the adjustment distance can be accurately recorded, so as to meet the conveying requirements of cardboards of different sizes, and the conveying accuracy is guaranteed.
