Description

Technical Field

[0001] The utility model relates to the technical field of paper packaging and printing machinery automation equipment, in particular to a transmission structure for negative pressure material suction and feeding. Background Art

[0002] With the increasing automation of paper packaging and printing machinery, the requirements for feeding equipment are also gradually increasing. For example, when printing paper bags, lunch boxes, and other paper, cardboard is difficult to avoid warping or surface unevenness due to its light weight and the different storage conditions of raw materials. These cardboards are extremely unstable during transportation, causing the printing equipment to start and stop frequently, which reduces the service life of the printing equipment. Based on this, in the existing technology, negative pressure suction material conveying equipment maintains the material in a fixed position, making the material transported by the negative pressure suction material conveying equipment less likely to warp significantly, thereby improving the quality of printing production. However, because the negative pressure suction material conveying equipment requires horizontal and vertical movement, the existing transmission structure is complex, prone to failure, and has high costs. Summary of the Invention

[0003] In order to solve the above technical problems, the present invention adopts the following technical solutions.

[0004] The utility model provides a transmission structure for negative pressure material suction and feeding, the transmission structure includes a motor, a cam, a transmission arm, a transverse sliding assembly, a vertical sliding assembly, a sliding assembly connecting plate, a limit rod, and a negative pressure assembly. The motor power output shaft is connected to the cam, one end of the transmission arm is rotatably connected to the cam, and the other end of the transmission arm is rotatably connected to the sliding assembly connecting plate. The transverse sliding assembly and the vertical sliding assembly are respectively arranged on the front and rear surfaces of the sliding assembly connecting plate, and the limit rod and the negative pressure assembly are arranged on the vertical sliding assembly.

[0005] The motor drives the cam to rotate, and the transmission arm connected to the cam pushes the horizontal sliding assembly to move. When the cam rotates to a certain angle, the free end of the cam pushes the limit rod to rise, and the limit rod drives the vertical sliding assembly to rise, thereby driving the negative pressure assembly to move horizontally and vertically, completing a set of actions.

[0006] Furthermore, the cam is elliptical, the connection point between the motor power output shaft and the cam is located in the middle part of the cam, one end of the transmission arm is rotatably connected to one of the tips of the cam, and the limit rod is in contact with the outer circle of the cam.

[0007] Furthermore, the transverse sliding assembly includes a transverse slider, a transverse slide rail, and a transverse slide rail seat. The transverse slide rail is arranged on the transverse slide rail seat. The back of the transverse slider is arranged on the sliding assembly connecting plate. The transverse slider is arranged on the transverse slide rail. When the motor is working, the transmission arm is pushed by the rotation of the cam, so that the transverse slider slides transversely on the transverse slide rail.

[0008] Furthermore, the vertical sliding assembly includes a vertical slider, a vertical slide rail, and a vertical slide rail seat. The vertical slide rail is arranged on the vertical slide rail seat. The back of the vertical slider is arranged on the sliding assembly connecting plate. The vertical slider is arranged on the vertical slide rail. The limit rod is arranged at the top of the vertical slide rail seat. When the motor is working, the limit rod is pushed up and down by the rotation of the cam, so that the vertical slider slides up and down on the vertical slide rail. The negative pressure assembly is arranged at the bottom end of the vertical slide rail seat.

[0009] Furthermore, the negative pressure assembly includes a negative pressure rod and a negative pressure nozzle. The negative pressure rod is connected to the vertical slide rail seat, and the negative pressure nozzle is arranged on the negative pressure rod.

[0010] Furthermore, the transmission structure further includes a seat plate, the motor is arranged on the outer side of the seat plate, the cam is arranged on the inner side of the seat plate, and the transverse slide rail seat is arranged on the inner side of the seat plate.

The driving wheel is power-connected to the driven wheel and is arranged on the outside of the seat plate. The motor power output shaft is connected to the driving wheel, and the cam is connected to the driven wheel.

[0012] Furthermore, the transmission structure also includes a transmission shaft and a connecting rod, and two of the cams, transmission arms, transverse sliding assemblies, vertical sliding assemblies, sliding assembly connecting plates, limit rods, seat plates, driving wheels, and driven wheels are each provided. The two seat plates are arranged at both ends of the connecting rod, and the two driving wheels are arranged at both ends of the transmission shaft. The two cams, transmission arms, transverse sliding assemblies, vertical sliding assemblies, sliding assembly connecting plates, limit rods, driving wheels, and driven wheels are mirror-imaged on the two seat plates.

[0013] Furthermore, the transmission structure also includes a belt and a tension pulley. The tension pulley is arranged on the outer side of the seat plate, and the driving pulley, the driven pulley and the tension pulley are connected by a belt.

[0014] The motor drives the driving wheel and the transmission shaft to rotate. The driving wheel drives the driven wheel to rotate through the belt. The tension wheel adjusts the tightness of the belt. The driven wheel is connected to the cam, so that the cam rotates. The rotation of the cam pushes the transmission arm, so that the horizontal slider on the connecting plate of the sliding assembly moves on the horizontal slide rail, thereby driving the negative pressure rod to move horizontally. When the cam rotates to a certain angle, the free end of the cam pushes the limit rod to rise, and the limit rod drives the vertical slide rail seat to rise, so that the negative pressure rod moves vertically, thereby realizing the horizontal and vertical movement of the negative pressure rod.

[0015] The utility model realizes the lateral and vertical movement of the negative pressure component through the mutual cooperation of the cam, the transmission arm, the limit rod, the lateral sliding component and the vertical sliding component. The structure is simple and stable, the failure rate is low, and the production cost is reduced due to the simple structure. BRIEF DESCRIPTION OF THE DRAWINGS
