Description

Technical Field

[0001] This utility model relates to the field of cardboard box technology, and in particular to a cardboard positioning mechanism for a die-cutting machine used in cardboard box processing. Background Technology

[0002] Cardboard boxes are the most widely used packaging products. Depending on the materials used, there are corrugated cardboard boxes, single-layer cardboard boxes, etc. In the cardboard box production process, a die-cutting machine is used to apply a certain pressure to cut the cardboard into a certain shape.

[0003] A search revealed a Chinese patent (application number "202122139963.8") disclosing a "cardboard positioning mechanism for a die-cutting machine in carton processing." This positioning mechanism includes a base, which is placed on the ground via bottom support legs; a fixed frame, welded to the upper surface of the base, with a hollow interior; a limiting block, a cylindrical structure rotatably mounted inside a limiting plate; a cardboard workpiece, placed on top of the base; and a die-cutting machine body, mounted on the front top of the base. Fixed rods are slidably mounted on both the left and right sides of the fixed frame, with a limiting plate of an "L"-shaped cross-section welded to the inner end of each rod. However, this positioning mechanism has the following problems:

[0004] 1. When limiting the cardboard, it is difficult to keep the movement distance of the limiting blocks on both sides consistent, which makes it impossible for the cardboard to be centered and has low practicality;

[0005] 2. When conveying the cardboard, the friction between the cardboard and the top of the device base is large, making it difficult to convey the cardboard into the die-cutting machine in a timely manner, resulting in low work efficiency. Utility Model Content

[0006] This utility model provides a cardboard positioning mechanism for a die-cutting machine used in carton processing, which solves the problems proposed in the prior art: the movement distance of the limiting blocks on both sides of the positioning mechanism is difficult to keep consistent, resulting in the cardboard not being centered, low practicality, and the large friction between the cardboard and the top of the device base, which makes it impossible to transport the cardboard into the die-cutting machine in a timely manner, resulting in low work efficiency.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A cardboard positioning mechanism for a die-cutting machine used in carton processing includes a base and a conveying assembly bolted to the outer wall of the die-cutting machine's feed end. The base has two fixed plates welded to its top outer walls, and each fixed plate has an adjusting assembly on one side. The adjusting assembly includes a servo motor bolted to one outer wall of the fixed plate, a first screw connected to one end of the servo motor's output shaft via a coupling, a second screw with one end passing through and connected to the outer wall of the fixed plate via a bearing, and two sliders respectively bolted to the outer walls of the first and second screws. Each fixed plate has a limiting assembly on one side, which includes a mounting frame bolted to the top outer wall of the two sliders, and a limiter bolted to the top outer wall of the mounting frame. The base has an infrared rangefinder on the wall and several limiting rollers with both ends penetrating through and connected to the outer wall of the mounting frame via bearings. The top of the base is equipped with a mounting frame, and the two sides of the mounting frame are respectively bolted to the outer wall of one side of two fixed plates. The mounting frame is equipped with two lifting assemblies. The lifting assembly includes a lifting cylinder bolted to the top outer wall of the mounting frame and a lifting plate bolted to the bottom of the piston rod of the lifting cylinder. The lower part of the two lifting plates is equipped with a pressing assembly. The pressing assembly includes a lifting frame, several pressing wheels with both ends penetrating through and connected to the outer walls of the lifting frame via bearings, four sliding rods respectively welded to the top outer wall of the lifting frame, and four return springs respectively sleeved on the outer walls of the four sliding rods.

[0009] Preferably, the conveying assembly includes two mounting plates welded to the top outer wall of the base, two connecting plates welded to the opposite outer walls of the two mounting plates, conveying rollers with both ends passing through and connected to the outer walls of the two mounting plates by bearings, transmission rollers with both ends passing through and connected to the outer walls of the two mounting plates by bearings, a conveyor belt sleeved on the outer walls of the conveying rollers and transmission rollers, several support rollers with both ends passing through and connected to the outer walls of the two mounting plates by bearings, and a conveying motor bolted to one outer wall of the mounting plate. The top ends of the several support rollers abut against the top inner wall of the conveyor belt. A first synchronous pulley is connected to the outer wall of one end of the conveying roller by a flat key. A second synchronous pulley is connected to one end of the output shaft of the conveying motor by a flat key, and the second synchronous pulley is connected to the first synchronous pulley by a synchronous belt to form a transmission engagement.

[0010] Preferably, each of the two fixing plates has a corner brace welded to one outer wall, and the four corner braces are respectively welded to the top outer wall of the base.

[0011] Preferably, one end of the first screw and the second screw are respectively connected to the outer wall of the mounting plate through bearings, and the outer walls of one end of the first screw and the second screw are each connected to a third synchronous pulley by a flat key, and the two third synchronous pulleys are connected to each other by a synchronous belt.

[0012] Preferably, two fixing rods are welded to one outer wall of the mounting frame, and the two fixing rods are respectively inserted through and slidably installed on the outer wall of the fixing plate.

[0013] The above scheme uses the servo motor output shaft to rotate, which drives the first screw and the second screw to rotate. The first screw and the second screw respectively drive the two sliders to move, which in turn drives the mounting frame and the infrared rangefinder to move. The infrared rangefinder measures the moving distance of the mounting frame to ensure that the limiting roller contacts the cardboard without squeezing it.

[0014] Preferably, two limiting rods are welded to the top outer wall of the lifting plate, and the two limiting rods pass through and are connected to the top outer wall of the mounting frame through bearings.

[0015] Preferably, the four slide rods are respectively installed through and slidably on the top outer wall of the lifting plate, and the top ends of the four return springs respectively abut against the bottom outer wall of the lifting plate, and limit blocks are screwed onto the top outer walls of the four slide rods.

[0016] The above scheme involves lowering the piston rod of the lifting cylinder, which in turn lowers the lifting frame and the extrusion wheel. The extrusion wheel contacts the cardboard, and at the same time, the lifting frame squeezes the return spring. This causes the extrusion wheel to slightly squeeze the cardboard under the tension of multiple return springs. Subsequently, the conveyor belt moves the cardboard, and the extrusion wheel rolls under the action of friction.

[0017] The beneficial effects of this utility model are as follows:

[0018] 1. The servo motor output shaft rotates, driving the first screw and the second screw to rotate. The first screw and the second screw respectively drive the two sliders to move, which in turn drives the mounting frame and the infrared rangefinder to move. The infrared rangefinder measures the moving distance of the mounting frame to ensure that the limiting roller contacts the cardboard without squeezing it. This ensures that the moving distance of the two mounting frames is the same, so that the cardboard always stays in the center position, improving practicality.

[0019] 2. The piston rod of the lifting cylinder descends, causing the lifting frame and the extrusion roller to descend as well. The extrusion roller contacts the cardboard, and at the same time, the lifting frame squeezes the return spring. This causes the extrusion roller to slightly squeeze the cardboard under the tension of multiple return springs. Subsequently, the conveyor belt moves the cardboard, and the extrusion roller rolls under the action of friction. This can limit the vertical position of the cardboard and promptly transport it into the die-cutting machine, improving work efficiency.

[0020] In summary, this utility model ensures that the two mounting frames move the same distance, keeping the cardboard centered and improving its practicality. It also limits the vertical position of the cardboard and allows for timely delivery of the cardboard to the die-cutting machine, thus improving work efficiency. Attached Figure Description
