Technical Field

[0001] The utility model relates to the technical field of die-cutting machines, in particular to a servo printing slotting die-cutting machine with a servo up-suction type pressure-free paper feeding at the leading edge of the paper feeding machine. Background Art

[0002] In the carton packaging industry, high-speed printing slotting and die-cutting machines are generally equipped with a paper feeder to improve production efficiency and reduce labor intensity. The paper feeder must ensure that its paper feeding speed can keep up with the printing speed of the high-speed printing slotting and die-cutting machine, so as to ensure that its working speed is not affected.

[0003] The traditional paper feeding mechanism needs to perform downward pressure feeding while feeding paper. The paper feeding unit and the printing unit use two sets of similar functions, the upper paper feeding pressure roller and the lower paper feeding pressure roller, to transport the cardboard. Through the relative rotation of the two, the cardboard delivered by the leading edge paper feeding unit is continuously transported to the paper feeding unit and the various printing units below. The traditional downward pressure paper feeding mechanism is easy to damage the cardboard, and the paper feeding efficiency is low, which affects production and processing. Utility Model Content

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] See also Figure 1-5 The utility model provides a technical solution: a servo printing slotting and die-cutting machine with servo upward suction type pressure-free paper feeding at the leading edge of the paper feed, comprising two mounting plates arranged parallel to each other, a common shaft 5 being rotatably mounted between the two mounting plates, and both ends of the shaft 5 respectively passing through the two mounting plates, a servo motor 4 being fixedly mounted on the inner side of any mounting plate, and the output end of the servo motor 4 passing through the mounting plate and being installed with a cam 2, a swinging rod 1 fixedly sleeved on the shaft 5 being provided above the cam 2, and the swinging rod 1 being adapted to the cam 2;

[0024] Several clamping blocks 10 are installed on the shaft 5, and the clamping blocks 10 are connected to the connecting rod 6 through the joint fulcrum 13. A leading edge suction box 15 is set between the two mounting plates, and a lip plate 15 is set on the top of the leading edge suction box 15. The connecting rod 6 is connected to the lip plate 17 through the joint fulcrum 13.

[0025] An auxiliary suction box 14 is provided above one side of the leading edge suction box 15, and a lip plate 2 13 is installed at the bottom of the auxiliary suction box 14. The bottom of the auxiliary suction box 14 and the top of the leading edge suction box 15 are both equipped with rubber wheels 8 through bearings. When lifted, the lip plate 17 is higher than the upper surface of the rubber wheel 8 by a height range of A to B on both sides. When lowered, the lip plate 17 is lower than the upper surface of the rubber wheel 8 by a height range of A1 to B1 on both sides. This effectively controls the adsorption and support of the cardboard 16, and controls the single cardboard to be fed to the bottom of the auxiliary suction box 14 at a uniform speed through the front baffle 12. The lip plate 2 13 is installed on the auxiliary suction box 14.

[0026] In the present invention, one end of the swing rod 1 is connected to a CF bearing, and the CF bearing and the cam 2 always maintain a tangent state. When the CF bearing contacts the high point of the cam 2, the lip plate 7 is in a raised state, and when the CF bearing contacts the low point of the cam 2, the lip plate 7 is in a lowered state.

[0027] In the present invention, a paperboard 16 is provided on the top of the lip plate 7.

[0028] In the present invention, a front baffle 12 is provided between the auxiliary suction box 14 and the leading edge suction box 15 through a bracket, and the paperboard 16 is fed to the auxiliary suction box 14 at a uniform speed by controlling the single paperboard via the front baffle 12 .

[0029] In the present invention, a rubber roller 11 is provided at the bottom of the auxiliary suction box 14 and is mounted through a bracket. When the cardboard 16 passes by, the cardboard 16 is sucked upward and gently supported by the rubber roller 11 below, thereby achieving pressure-free paper feeding and achieving high efficiency and energy saving.

[0030] In the present utility model, the side of the lip plate 7 close to the auxiliary suction box 14 is rotatably mounted on the mounting plate through the joint fulcrum 2 9. The two ends of each connecting rod 6 are respectively connected to the clamping block 10 and the paper feed side of the lip plate 7 by the joint fulcrum 3, and the other side of the lip plate 7 is connected to the joint fulcrum 2 9. When the swing arm 1 swings, it drives the shaft 5 to rotate, and the rotation of the shaft 5 drives the connecting rod 6 to move up and down by the clamping block 10, thereby controlling the lifting and lowering of the lip plate 7 on the suction box 15 at the leading edge of the paper feed.

[0031] The utility model: driven by the servo motor 4 below the leading edge suction box 15, the cam 2 is driven to rotate, the swing arm 1 is connected to the shaft 5, and one end is connected to the CF bearing. The CF bearing and the cam 2 always maintain a tangent state. When the CF bearing contacts the high point of the cam 2, the lip plate 7 is in a raised state. When the CF bearing contacts the low point of the cam 2, the lip plate 7 is in a lowered state. A number of clamping blocks 10 are installed on the shaft 5. The two ends of each connecting rod 6 are respectively connected to the clamping block 10 and the paper feeding side of the lip plate 7 by the joint fulcrum 3, and the other side of the lip plate 7 is connected to the joint fulcrum 2 9. When the swing arm 1 swings, it drives the shaft 5 to rotate, and the rotation of the shaft 5 drives the connecting rod 6 to move up and down by the clamping block 10, thereby controlling the lifting and lowering of the lip plate 7 on the leading edge suction box 15 of the paper feeding. Figure 4-5 As shown, when the lip plate 1 is raised, the height range of the lip plate 7 above the upper surface of the rubber wheel 8 on both sides is A-B. When it is lowered, the height range of the lip plate 17 below the upper surface of the rubber wheel 8 on both sides is A1-B1, which effectively controls the adsorption and lifting of the cardboard 16, and controls the single cardboard to be fed at a uniform speed to the auxiliary suction box 14 through the front baffle 12. The auxiliary suction box 14 is equipped with a lip plate 2 13. When the cardboard 16 passes by, the cardboard 16 is sucked upward and gently supported by the rubber roller 11 below, thereby achieving a pressure-free paper feeding effect and achieving high efficiency and energy saving.
