Description

Technical Field

[0001] The utility model relates to the technical field of edge pressing processing of carton gluing machines, in particular to an edge pressing mechanism of a packaging carton gluing machine. Background Technique

[0002] A carton gluing machine for packaging and printing is a machine that folds and glues the edges of printed and die-cut cardboard sheets in packaging and printing. It generally includes a sheet feeding mechanism for successively feeding sheets one by one, a folding mechanism for folding the edges of the sheets along the die-cut lines, a gluing structure for applying glue to the folded edges, an edge pressing mechanism for pressing the glued parts of the sheets, and a material collecting mechanism for collecting the cartons.

[0003] In the prior art, the Chinese utility model patent with the application number 202321729195.4 relates to a edge pressing machine for carton gluing machine production, including a conveyor belt, a support plate, a roller motor, a cross bar, a cylinder and a transmission track, which can ensure the balance when the cylinder descends for pressing and the stability during work, and will not cause the deviation of the pressing position and the damage of components due to continuous up and down transmission.

[0004] However, the above device will squeeze the whole carton during actual use. For cartons with longer folded edge lengths at both ends and the folded edges overlapping up and down in the middle of the carton, the thickness of the overlapping part will be greater than that of the bent part, resulting in a decrease in the edge pressing effect on the bent part of the device. Content of the Utility Model

[0005] To solve the above technical problems, the utility model provides an edge pressing mechanism of a packaging carton gluing machine, which transports the bent paper sheets through a conveying device, adjusts the edge pressing position according to the size of the paper sheets through a transverse movement device, squeezes the bent area of the paper sheets through an edge pressing device, and adjusts the edge pressing process through an adjusting device in cooperation with the edge pressing device to adapt to paper sheets of different thicknesses, thereby improving the practicability of the device.

[0006] The edge pressing mechanism of a packaging carton gluing machine of the utility model includes a conveying device, a transverse movement device, an edge pressing device and an adjusting device. The adjusting device is installed on the transverse movement device, the edge pressing device is installed on the transverse movement device, and the adjusting device is installed on the transverse movement device.

[0007] Preferably, the conveying device includes a frame, a first speed reducer, a first motor, a conveying shaft, a carrying roller and a conveyor belt. A first speed reducer is installed on the right part of the front end face of the frame, and a first motor is installed on the first speed reducer. A plurality of groups of conveying shafts are horizontally installed in the frame. A group of carrying rollers are symmetrically sleeved on the front and rear of each group of conveying shafts respectively. Two conveyor belts are respectively sleeved on the plurality of carrying rollers at the front and rear of the plurality of conveying shafts. The output end of the first speed reducer passes through the front end face of the frame and is connected to the rightmost conveying shaft. When the first motor is started, the power is transmitted to the connected conveying shaft through the first speed reducer, driving the conveying shaft to rotate. The paper is transported on the conveyor belt through the transmission of a plurality of groups of carrying rollers and two conveyor belts. The front and rear parts of the paper are supported by the two conveyor belts. The gap between the two conveyor belts facilitates taking out the paper from the gap when the equipment fails and stops, improving the practicability of the device.

[0008] Preferably, the transverse movement device includes a second speed reducer, a second motor, a bidirectional lead screw, a top plate, a side plate and a nut. A group of second speed reducers are respectively installed on the left and right of the upper part of the front end face of the frame, and a second motor is installed on the second speed reducer.

[0009] Preferably, it further includes a plurality of groups of limit optical rods. A plurality of groups of limit optical rods are horizontally installed inside the frame. The plurality of groups of limit optical rods respectively pass through the sides of the top plate and the side plate.

When the reduction motor is started, the power is transmitted to the conveying roller, driving the conveying roller to rotate, making the lower end face of the extrusion conveyor belt relatively stationary with the upper end face of the conveyor belt. The lower end face of the extrusion conveyor belt presses the paper through the cooperation of the conveying roller and the extrusion conveyor belt, so as to facilitate the edge pressing device to perform edge pressing operation on the edge of the paper, improving the practicability of the device.

Multiple sets of pressing rollers are horizontally installed on the bearing frame, and multiple sets of pressing rollers are respectively located above multiple sets of bearing rollers. By controlling the telescopic movement of the first electric cylinder, the multiple sets of pressing rollers on the bearing frame are driven to move up and down. The lower part of the extrusion conveyor belt is squeezed by the multiple sets of pressing rollers, so as to perform extrusion operation on the edge of the paper sheet. By arranging two sets of edge pressing devices before and after, the device only presses the edge part of the paper sheet. The pressure on the moving end of the first electric cylinder is monitored by the first pressure sensor to prevent the paper sheet from being distorted due to the change in the moving speed between the front and rear parts of the paper sheet caused by excessive pressure, improving the practicability of the device.

[0012] Preferably, the adjusting device includes a second electric cylinder, a second pressure sensor, a second bearing frame and an adjusting roller. The second electric cylinder is installed in the middle of the lower end surface of the top plate.
