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 down-suction type pressure-free paper feeding at the leading edge of the paper feeding machine. Background Art

[0002] The carton printing slotting and die-cutting machine uses a paper feeding mechanism to feed the cut cardboard one by one into the paper feeding unit of the carton printing slotting and die-cutting machine, and then the paper feeding unit sends the cardboard to the printing, slotting and die-cutting unit at the back for printing and forming processing.

[0003] The paper feeding process is the most commonly used process for packaging and printing products. The existing paper feeding unit design is relatively simple. The paper feeding unit and the printing unit use two sets of similar functions: upper and lower paper feeding rollers 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 prone to damage the cardboard, resulting in low paper feeding efficiency. Utility Model Content

[0004] The purpose of the utility model is to provide a servo printing slotting and die-cutting machine with a servo downward suction type pressure-free paper feeding at the leading edge of the paper feeding, so as to solve the problems raised in the above background technology.

[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 a servo downward 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 an output end of the servo motor 4 passing through the mounting plate and being mounted with a cam 2, a swinging rod 1 being 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 3. A leading edge suction box 16 is set between the two mounting plates, and a lip plate 7 is set on the top of the leading edge suction box 16. The connecting rod 6 is set at the bottom of the lip plate 7;

[0025] An auxiliary suction box 15 is provided on one side of the leading edge suction box 16, and a lip plate 2 14 is provided on the top of the auxiliary suction box 15. Multiple rubber wheels 8 are installed on the top of the auxiliary suction box 15 and the leading edge suction box 16 through bearings. When the lip plate 7 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 7 below the upper surface of the rubber wheel 8 on both sides is A1~B1, which effectively controls the adsorption and support of the cardboard, and controls the uniform speed of feeding the single cardboard to the auxiliary suction box 15 through the front baffle 13.

[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 17 is provided on the top of the lip plate 7.

[0028] In the present invention, a front baffle 13 is provided between the auxiliary suction box 15 and the leading edge suction box 16 through a bracket, and the front baffle 13 controls the single paperboard to be fed to the auxiliary suction box 15 at a uniform speed.

[0029] In the present invention, a paper pressing roller 11 is provided on the top of the auxiliary suction box 15 and is mounted through a bracket. A plurality of rubber wheels 12 are fixedly mounted on the paper pressing roller 11 at equal intervals. When the paperboard 17 passes by, it is carried by the rubber wheels 12 on the upper paper pressing roller 11, thereby playing the role of pressure-free paper feeding and achieving the effect of high efficiency and energy saving.

[0030] In the present invention, the side of the lip plate 7 close to the auxiliary suction box 15 is rotatably mounted on the mounting plate through the joint fulcrum 2 9, so that when the swing arm 1 swings, the shaft 5 is driven to rotate, and the rotation of the shaft 5 drives the connecting rod 6 to move up and down through the clamping block 10, thereby controlling the lifting and lowering of the lip plate 7 on the leading edge suction box 16.

[0031] The utility model is driven by the servo motor 4 under the leading edge suction box 16, which drives the cam 2 to rotate, and the swing rod 1 is connected to the shaft 5. One end of the swing rod 1 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 plurality 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 rod 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 16. 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 1 is A to B on both sides. When the lip plate 1 is lowered, the height range of the lip plate 7 below the upper surface of the rubber wheel 1 is A1 to B1 on both sides. This effectively controls the adsorption and release of the cardboard, and controls the uniform speed of feeding the single cardboard to the auxiliary suction box 15 via the front baffle 13. The auxiliary suction box 15 is equipped with a lip plate 2 14. When the cardboard 17 passes by, it is carried by the rubber wheel 2 12 on the upper paper pressing roller 11, achieving a pressure-free paper feeding effect and achieving high efficiency and energy saving.
