DETAILED DESCRIPTION

[0030] The following embodiments are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0031] An embodiment of the present utility model is a stamping device, comprising a mounting seat 1, a driving mechanism, and a printing shaft 2, a printing wheel 3, and a pressure wheel 4 arranged on the mounting seat 1. The printing wheel 3 is arranged at one end of the printing shaft 2 and cooperates with the pressure wheel 4. The other end of the printing shaft 2 is provided with a first bearing 21, a transmission member 22, and a second bearing 23 in sequence. The first bearing 21 and the second bearing 23 are connected to the mounting seat 1, and the transmission member 22 is connected to the driving mechanism.

[0032] In this embodiment, the printing shaft 2 is connected to the mounting seat 1 through two bearings. Specifically, Figure 1-3 As shown, one end of the printing shaft 2 is clamped with a clamping sleeve 8 that can be axially extended and rotationally adjusted. The clamping sleeve 8 is then clamped with a pressing sleeve 7, and then fixed to the outer end of the pressing sleeve 7 by a screw 20. The printing wheel 3 is sleeved on the pressing sleeve 7. The position of the printing wheel 3 is adjusted by adjusting the axial extension position of the clamping sleeve 8 to better cooperate with the pressing wheel 4. The rotation angle of the clamping sleeve 8 is adjusted to adapt to the width change of the paper box and adjust the horizontal position when stamping steel characters. It is more convenient to adjust and replace the printing wheel 3 without disassembling too many parts. No readjustment is required; the printing wheel 3 adopts a single-wheel structure, which is more convenient to use; the other end of the printing shaft 2 is provided with a first bearing 21, a transmission member 22 and a second bearing 23 in sequence, the first bearing 21 and the second bearing 23 are connected to the mounting seat 1, and the transmission member 22 is provided with a printing shaft gear 6, which is connected to the driving mechanism. By lengthening the distance between the two bearings, the angular deviation caused by the bearing ball gap is reduced, thereby reducing the deviation of the printing shaft 2, so that the depth of the steel characters embossed by the printing wheel 3 is consistent;

[0033] The pressure wheel 4 is fixed to one end of the eccentric gap adjustment shaft 5 by a screw 20, and the other end of the eccentric gap adjustment shaft 5 is slidably mounted on the mounting base 1, so that the position of the pressure wheel 4 can be adjusted by adjusting the extended length of the eccentric gap adjustment shaft 5 so as to better cooperate with the printing wheel 3, and the gap between the pressure wheel 4 and the printing wheel 3 can be adjusted by adjusting the angle of the eccentric gap adjustment shaft 5 to adapt to the thickness of different papers.

[0034] In this embodiment, the driving mechanism includes: a driving source connected to a power shaft, the power shaft is connected to a power shaft sprocket 11, the power shaft sprocket 11 is connected to a speed change shaft sprocket 13 through a chain 12, and a tensioning sprocket 14 is provided outside the chain 12 for adjusting the tension of the chain 12, the speed change shaft sprocket 13 is mounted on a speed change shaft 16, one end of the speed change shaft 16 is mounted with a speed change gear 15, the speed change gear 15 is meshed with a steering gear 17, the steering gear 17 is mounted on one end of a steering shaft 18, the other ends of the speed change shaft 16 and the steering shaft 18 are both mounted on a reduction seat 19, and the steering gear 17 is meshed with the printing shaft gear 6, as shown in FIG. Figure 3 As shown; the speed change shaft 16 and the steering shaft 18 are installed on the same reduction seat 19, which reduces the space volume, is easy to process and install, and has less cumulative error; the outer ends of the speed change gear 15 and the steering gear 17 are locked and positioned by screws 20, which effectively prevents the axial movement of the gears, and has a simple structure and fewer parts; similarly, the outer ends of the pressure wheel 4 and the printing wheel 3 are also locked with rivets by screws 20, which effectively prevents axial movement.

[0035] In addition, both sides of the mounting base 1 are fixed between the positioning block 10 and the rotating pressing block 9, and the positioning block 10 and the rotating pressing block 9 are rotatably connected, and are connected here by screws 20, so that by loosening the screws 20 and changing the position of the rotating pressing block 9, the mounting base 1 can be quickly disassembled; Figure 4 As shown, finger latches are provided on both sides of the mounting base 1, which makes it easier to hold the printing wheel 3 when changing it, and prevents it from slipping and falling; a screw 20 is also provided on one side of the mounting base 1 for latching the printing shaft 2, and a small top screw is built in to latch it, which is marked "the screw must be 5mm out to operate", and the latching function when changing steel characters is integrated to avoid the disadvantage that the small split latch parts are easily lost on site; the mounting base 1 and the reduction base 19 are made of medium carbon steel heat-treated to obtain rigidity and hardness.

[0036] Therefore, the transmission process of this embodiment is: the driving source drives the power shaft sprocket 11 through the power shaft, the power shaft sprocket 11 drives the speed change shaft sprocket 13 through the chain 12, the speed change shaft sprocket 13 drives the speed change gear 15 through the speed change shaft 16, the speed change gear 15 drives the meshing steering gear 17, the steering gear 17 drives the meshing printing shaft gear 6, the printing shaft gear 6 is transmitted to the printing wheel 3 through the printing shaft 2 for rotation, and the printing wheel 3 and the pressure wheel 4 are frictionally transmitted, thereby printing steel characters on the paper box between the printing wheel 3 and the pressure wheel 4.
