The invention relates to a method for positioning a paper money number image region. The method comprises the following steps: acquiring a horizontally arranged single paper money image; acquiring the appearing region of the number of the current paper money image, respectively selecting two rows in each region, and acquiring the proportion of the quantity of pixels with the pixel values less than an upper threshold F accounting for the total quantity of the pixels; carrying out [-1, 0, 1] Sobel gradient calculation respectively on the pixels of each row in each region, and acquiring the proportion of the quantity of the pixels with the gradient calculated values larger than a lower threshold G accounting for the total quantity of the pixels; respectively calculating the sums of V1 and V2 of the sampling rows in the four regions, searching for the maximum value of the sums of V1 and V2, and taking the region corresponding to the maximum value as a number region; and amplifying the image of the number region, carrying out slant and longitudinal draw correction on the amplified image, removing the blank region of the image of the number region, and identifying characters of the image of the number region. The method disclosed by the invention has the advantages that the paper money number region can be accurately positioned and the reliability is high.

The invention relates to the field of financial equipment, and discloses a paper currency plastic enveloping machine. The machine comprises a pre-binding part, a transition part and a plastic-enveloping thermal shrinking part, wherein the pre-binding part is connected with a paper currency receiving device; a positioning window is arranged in one sidewall of the plastic-enveloping machine; the paper currency receiving device comprises a first base plate, a paper currency receiving part for positioning paper currency, a guide assembly and a driving assembly; the guide assembly and the driving assembly are arranged on the first base plate; the paper currency receiving part is arranged on the guide assembly; one end of the guide assembly is arranged at the positioning window, and the other end of the guide assembly extends into the plastic-enveloping machine; the driving assembly can drive the paper currency receiving part to reciprocate on the guide assembly. According to the paper currency plastic enveloping machine, the paper currency can be manually positioned on the paper currency receiving part from the positioning window, and then the driving assembly can be operated to drive the paper currency receiving part to reciprocate along the guide assembly so as to finish the processes of automatically conveying the paper currency and returning to a start point. Therefore, that the paper currency is manually conveyed to a specified position in the paper currency plastic enveloping machine can be avoided, and as a result, the paper currency conveying process is saved, and the paper currency conveying efficiency is improved.

The invention discloses a tube coiling machine for a quick-dry firework paper tube. A softening mechanism is arranged between a raw paper coil and a gluing mechanism. The softening mechanism comprises two paper positioning parts which are arranged in a front-back manner in the paper feeding direction. A softening part is arranged between the two paper positioning parts. The softening mechanism further comprises a paper relieving part between the raw paper coil and a paper V-shaped folding part. The softening mechanism positions paper for V-shaped folding, and the paper redundancy is preset for compensating for dragging of the paper during state switching of the softening part. The tube coiling machine can complete softening treatment on sealing paper on the outer ring of the firework paper tube in the tube coiling working process, the sealing effect can be ensured without wetting the paper through water dipping, and the paper tube can be prevented from being baked and basked and is rapidly dried; meanwhile, the phenomenon of paper snapping is avoided, and running is reliable and stable; the tube coiling machine is particularly suitable for work of tube coiling borers with paper inserting gaps; and the production efficiency can be effectively improved, and the quality of finished paper tube products is better improved.

The invention discloses an unpacking positioning mechanism of a full-automatic packing machine, which is used for positioning paper boxes in a folding state before. The unpacking positioning mechanism comprises a rectangular support, a left-right positioning device, an opposite angle positioning device, and a paper box unfolding device, wherein the rectangular support is provided with a base, the left-right positioning device is provided with two first positioning components symmetrically arranged at the left and right sides of the base, the opposite angle positioning device is provided with two second positioning components symmetrically arranged at the front and rear sides of the base, and the paper box unfolding device comprises a first unfolding component connected to the first positioning components and a second unfolding component connected to the second positioning components. According to the unpacking positioning structure provided by the invention, the first positioning components of the left-right positioning device are used for positioning and unfolding the left and right sides of a folded paper box, the two second positioning components of the opposite angle positioning device enable an included angle between any two adjacent sides of the paper box to be a right angle, and thus the section of the unpacked paper box is rectangular or square.

The invention discloses a fully automatic scrolling and packaging machine for hanging pictures, which is composed of a machine body and a finished product conveyor belt fixed on the machine body, a lifting platform, a rolling device, a gluing device, and a lower scroll device. The above body preferably adopts upper and lower frames The lower frame is larger than the upper frame. The finished product conveyor belt, lifting platform and rolling device are all fixed on the top surface of the lower frame. The finished product conveyor belt and the lifting platform are arranged horizontally, and the rolling device is vertical to both. The gluing device and the falling picture scroll device are fixed by a fixed plate, and the fixed plate is fixed on the upper frame.
