Description

Technical Field

[0001] The utility model belongs to the technical field of corrugated paper processing, in particular to a paper feeding mechanism of a corrugated paper printing machine. Background Art

[0002] Corrugated paper typically refers to corrugated cardboard, a sheet made from multiple layers of corrugated paper bonded together. The serrated protrusions of the corrugated paper create multiple triangular areas within the cardboard, enhancing its bending resistance. It is widely used in various packaging cartons, allowing it to withstand bumps and falls during transportation and effectively protect the contents. The production of corrugated boxes often requires a printing step, and corrugated paper printing presses typically use a pressure feed method.

[0003] To this end, Chinese patent CN201922009476.2 discloses a paper feeding mechanism of a corrugated paper printing machine. The pressure is detected by a pressure sensor. If the pressure is too high, the paper pressing roller group is adjusted to move upward, and if the pressure is too low, the paper pressing roller group is adjusted downward to avoid excessive pressure, which may cause the corrugated cardboard to be easily crushed and affect the subsequent printing accuracy, or too low pressure, which may cause insufficient friction between the corrugated paper and the paper feeding roller, and the corrugated paper may slip and deviate, thereby effectively improving the efficiency and accuracy of corrugated paper printing.

[0004] Although this patent can transmit corrugated paper of different thicknesses, the different positions of the corrugated paper cause the position of the corrugated paper to be offset, which in turn causes deviations in subsequent work. Utility Model Content

[0005] The present invention aims to solve the problem that the existing technology can transport corrugated paper of different thicknesses, but the positions of the corrugated paper are different, which leads to the position deviation of the corrugated paper and the deviation of subsequent work. The following technical solutions are proposed:

[0006] The top end of the driving member is engaged with the gear train of claim 1, wherein the guide rail is located adjacent to the driving member, and the guide rail is connected along the top end of the driving member to the longitudinal direction of the transmission gear.

[0007] Preferably, the push plate and the fixing bar are parallel to each other and perpendicular to the horizontal plane, and the lower end of the fixing bar is in contact with the upper end of the base.

[0008] Preferably, the rack and the spur rack have the same size.

[0009] Preferably, a fixing groove is sleeved on the outer side of the rack, the rack is slidably connected to the inside of the fixing groove, and the fixing groove is fixedly installed on the top surface of the base.

[0010] Preferably, the groove fixing rod is fixedly mounted on the upper end of the base, and the straight rack fits in the interior of the groove fixing rod.

[0011] Preferably, a groove channel is provided inside the movable groove, a threaded hole is provided on the upper end of the groove plate, and the bolt is threadedly connected to the threaded hole on the upper end of the groove plate.

[0012] The beneficial effects of the utility model are:

[0013] (1) The position of the corrugated paper can be adjusted so that the corrugated paper is located in the middle of the paper feed roller group, which changes the time required for positioning during printing, thereby facilitating subsequent processing of the corrugated paper and improving the accuracy of corrugated paper processing;

[0014] (2) It can avoid the situation where the upper and lower positions of the corrugated paper overlap when the corrugated paper is pushed, so that a single corrugated paper moves between the paper pressing roller group and the paper feeding roller group, thereby achieving the purpose of conveying the corrugated paper one by one.

[0020] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0021] Example 1

[0022] The utility model provides a paper feeding mechanism of a corrugated paper printing machine, such as Figure 1-4 As shown, it includes: a paper pressing roller group 1, a paper feeding roller group 2 is provided at the lower end of the paper pressing roller group 1, a base 3 is provided at the lower end of the paper feeding roller group 2, a side end of the base 3 is fixedly connected to a fixed plate 4, a cylinder 5 is installed at the side end surface of the fixed plate 4, and a push plate 6 is fixedly installed on one end surface of the cylinder 5. A rack 8 is welded to the lower end of the push plate 6, and a gear 9 is meshed with the top of the rack 8. The gear 9 is rotatably connected to the base 3, and a straight rack 10 is meshed with the outer side of the gear 9. A groove fixing rod 11 is sleeved on the outer side of the straight rack 10, and a fixing bar 12 is welded to one end surface of the straight rack 10. The top of the base 3 is fixedly connected to the bottom end of the groove plate 15, and a movable groove 14 is slidably connected to the inner side of the groove plate 15. A baffle 13 is welded between the two movable grooves 14, and a bolt 16 is installed on the upper end of the groove plate 15 through a thread.

[0023] like Figure 1 and Figure 2 As shown, the push plate 6 and the fixing bar 12 are parallel to each other and perpendicular to the horizontal plane. The lower end of the fixing bar 12 is in contact with the upper end of the base 3, which facilitates the installation of the fixing bar 12 and enables the push plate 6 and the fixing bar 12 to move simultaneously.

[0024] like Figure 1 and Figure 3 As shown, the rack 8 has the same size as the spur rack 10 , and the lower end face of the rack 8 is snap-connected with a fixing groove 7 . The rack 8 fits in the fixing groove 7 , which can facilitate the synchronous relative displacement of the rack 8 and the spur rack 10 .

[0025] like Figure 2 and Figure 3 As shown, the outer side of the rack 8 is sleeved with a fixed groove 7, the rack 8 is slidably connected to the inside of the fixed groove 7, and the fixed groove 7 is fixedly installed on the top surface of the base 3 to prevent the straight rack 10 from sliding and achieve the purpose of supporting the straight rack 10.

[0026] like Figure 2 and Figure 4 As shown, a groove is provided inside the movable groove 14, and a threaded hole is provided at the upper end of the groove plate 15. The bolt 16 is threadedly connected to the threaded hole at the upper end of the groove plate 15, so that the movable groove 14 can slide inside the groove plate 15, and the bolt 16 fixes the movable groove 14 to the groove plate 15 through the thread, so that the height of the movable groove 14 can be adjusted, so that the baffle 13 reaches the required height.

[0027] Working principle: During actual use of the device, the cylinder 5 is started, and the movement of the cylinder 5 drives the push plate 6, which drives the rack 8 to slide. The rack 8 moves along the inner side of the fixed groove 7, and the movement of the rack 8 drives the rotation of the gear 9. The rotation of the gear 9 also drives the movement of the spur rack 10, which moves along the inner side of the groove fixed rod 11. The sliding of the spur rack 10 drives the fixed bar 12. When the corrugated paper enters the device, the push plate 6 and the fixed bar 12 can simultaneously move and clamp the corrugated paper, so that the corrugated paper can be placed flat in the same horizontal position, which shortens the time required for positioning during printing, thereby improving the efficiency of corrugated paper printing.

[0028] And rotate the bolt 16, one end of the bolt 16 slides along the groove inside the movable groove 14, and the movable groove 14 slides along the inside of the groove plate 15. When the baffle 13 at the side end of the movable groove 14 reaches the height of the upper end of the corrugated paper, rotate the bolt 16, and the bolt 16 fixes the movable groove 14 and the groove plate 15, so that the corrugated paper moves along the bottom end of the baffle 13, abuts the corrugated paper, and prevents the two corrugated papers from synchronously entering between the paper pressing roller group 1 and the paper feeding roller group 2.

[0029] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same.
