[0002] In the die-cutting industry, when auxiliary feeding materials are shipped, customers require them to be folded, with 6 pieces per stack. Each time they are folded for shipment, the auxiliary materials need to be manually folded and then pressed flat before being shipped. Customers require the auxiliary materials to be folded and pressed neatly like a military blanket, but manual folding is inefficient, which affects the shipping efficiency and the folding quality is inconsistent, resulting in relatively poor customer satisfaction. At the same time, manual operation requires a large number of people, requiring 5 people to meet the daily shipment volume of 50,000 pieces. Each person needs to be paid 300 yuan per day for labor, which is not commensurate with the effort and the return, resulting in high production costs. Utility Model Content

[0024] The utility model will be specifically introduced below in combination with the drawings and specific embodiments.

[0025] As shown in Figure 1 and 2 , the embodiment is a die cutting auxiliary material Z-shaped automatic folding device, including a feed roller 1, a feeding compression shaft 2, a feeding roller 3, a positioning scraper 4, a thrust scraper 5, a scraper driving mechanism and a discharge compression shaft 6, wherein the feed roller 1, the feeding compression shaft 2, the feeding roller 3 and the discharge compression shaft 6 are sequentially arranged along the material 7 advancing direction, the feed roller 1 is used to release the material 7, the feeding compression shaft 2 includes two upper and lower parallel shaft bodies one, the material 7 passes between the two shaft bodies one and is tightly clamped by the two shaft bodies one; the positioning scraper 4 is located below the feeding roller 3, the material 7 passes between the outer circumferential surface of the feeding roller 3 and the top surface of the positioning scraper 4 and is tightly clamped by the feeding roller 3 and the positioning scraper 4, the feeding roller 3 is used to forward intermittent conveying of the material 7, the positioning scraper 4 has a positioning inclined surface 41, and the corner between the top surface of the positioning scraper 4 and the positioning inclined surface 41 constitutes a first bending angle 11; the thrust scraper 5 has a first inclined surface 51 and a second inclined surface 52, the corner between the first inclined surface 51 and the second inclined surface 52 constitutes a second bending angle 12, the scraper driving mechanism is used to drive the thrust scraper 5 to act, so that the first inclined surface 51 of the thrust scraper 5 is close to the positioning inclined surface 41 of the positioning scraper 4, the material 7 is clamped between the first inclined surface 51 and the positioning inclined surface 41, and the material 7 is bent at the first bending angle 11 and the second bending angle 12; the discharge compression shaft 6 is used for forward intermittent conveying of the material 7 synchronously with the feeding roller 3.

[0026] In the embodiment, the position of the discharge compression shaft 6 is lower than the position of the feeding roller 3; one end of the feeding roller 3 is provided with a feeding servo motor for driving the feeding roller 3 to rotate, and the feeding roller 3 conveys a certain length of material 7 forward every time the feeding servo motor works; the discharge compression shaft 6 includes two upper and lower parallel shaft bodies two, the material 7 passes between the two shaft bodies two and is tightly clamped by the two shaft bodies two, and one end of one of the shaft bodies two is provided with a discharge servo motor for driving the corresponding shaft body two to rotate, and the discharge servo motor and the feeding servo motor operate synchronously.

[0027] In the embodiment, the scraper driving mechanism adopts an electric push rod, which provides driving force for the thrust scraper 5; in actual application, the scraper driving mechanism can also adopt a pneumatic cylinder or a hydraulic cylinder, which provides driving force for the thrust scraper 5.

[0028] like Figures 1-3 As shown, in this embodiment, a cursor 8 is set at the bending point 71 of the material 7, and a cursor sensor 9 is set at the first bending angle 11. The cursor sensor 9 is used to detect the cursor 8 on the material 7 to determine the length of the material 7 when it is conveyed forward. A seam line 72 corresponding to the cursor 8 is set at the bending point 71 of the material 7. Multiple products 10 are equally spaced between two adjacent seam lines 72. The distance between two adjacent seam lines 72 is equal to the length of the first inclined surface 51.

[0029] In this embodiment, during production operations:

[0030] The feeding servo motor starts and stops once, driving the feeding roller 3 to convey a certain length of material 7 forward. This material 7 has two bends 71, one of which stops precisely at the first bend angle 11. Figure 1 As shown; then the electric actuator drives the thrust scraper 5 to move, causing the first inclined surface 51 of the thrust scraper 5 to approach the positioning inclined surface 41 of the positioning scraper 4.

Figure 2 As shown; at this time, the first bending angle 11 bends one of the bending points 71 of this material 7, and the second bending angle 12 bends the other bending point 71 of this material 7, thus forming a Z-shaped fold; then the electric actuator drives the thrust scraper 5 to move, so that the first inclined surface 51 of the thrust scraper 5 moves away from the positioning inclined surface 41 of the positioning scraper 4; after bending, this material 7 is conveyed forward by the synchronously moving discharge pressing shaft 6 when the feeding servo motor drives the feeding roller 3 for the next start-up operation, and so on.

[0031] like Figure 4 As shown, after bending, the material 7 is cut as needed, folded in a Z-shape, and then pressed and sealed for shipment.
