Description

Technical Field

[0001] The utility model relates to the technical field of corrugated paper production, in particular to a discharging device for a corrugated paperboard production line. Background Art

[0002] Corrugated paperboard, also known as corrugated paperboard, is a multi-layer adhesive body, which consists of at least one layer of corrugated core paper and one layer of paperboard. It has high mechanical strength and can withstand collisions and falls during transportation, and is widely used in the packaging of various products. With the increasing demand for corrugated paperboard, in the face of the requirements of corrugated box users for more specifications, smaller quantities, and faster delivery, the production equipment of corrugated paperboard also needs to be constantly improved and upgraded. The formed corrugated paperboard falls from the discharge port of the production line. The existing production line lacks the function of discharging and sorting. The corrugated paperboard is stacked in a messy manner, which is not convenient for transportation and requires manual sorting before transportation. Utility Model Content

[0003] In view of the shortcomings of the prior art, a discharging device for a corrugated cardboard production line is disclosed, which comprises a discharging conveyor belt, a mounting frame is straddled on the discharging conveyor belt, a first electric push rod is mounted on the lower wall of the mounting frame, a pressing plate is connected to the first electric push rod, a material sensor is embedded in the lower wall of the pressing plate, and a top plate is mounted on the end of the pressing plate away from the material sensor;

[0004] Clamping plates are symmetrically arranged in the front and back of the mounting frame, and second electric push rods are arranged on the clamping plates. The second electric push rods are installed on the side walls of the mounting frame, and contact sensors are embedded on the surfaces of the clamping plates close to each other.

[0005] Preferably, a plurality of rollers are provided on the lower wall of the pressure plate.

[0006] Preferably, the roller and the pressing plate are connected via a connecting structure.

[0007] Preferably, the connection structure includes a sleeve, a connecting rod is slidably arranged in the sleeve, the connecting rod and the sleeve are connected by a spring, the lower end of the connecting rod slides through the sleeve, and the roller is installed on the corresponding connecting rod.

[0008] Preferably, a sliding groove is provided on the inner wall of the sleeve, a sliding block is slidably arranged in the sliding groove, and the sliding block is fixedly connected to the connecting rod.

[0009] The utility model has the following beneficial effects: the utility model has a reasonable structure and a novel design. When in use, the material is transported on the discharging conveyor belt, and the first electric push rod drives the pressure plate to descend, thereby causing the top plate to descend, so that the material is pressed against the top plate. The second electric push rod controls the clamping plate to approach the material and corrects the clamping plate. After the material is corrected, both ends of the material contact the contact sensor, and the controller controls the second electric push rod and the first electric push rod to retract. Under the action of the spring, the roller is still pressed on the material to avoid the material from warping when moving up on the top plate. As the first electric push rod gradually shrinks, the roller is separated from the material. After the top plate is separated from the material, the sorted material is normally transported on the discharging conveyor belt, which is convenient for subsequent operations.

DETAILED DESCRIPTION

[0013] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0014] See also Figure 1-2 , a discharging device for a corrugated cardboard production line, comprising a discharging conveyor belt 1 for transporting materials, a mounting frame 2 being spanned across the discharging conveyor belt 1, a first electric push rod 3 being mounted on the lower wall of the mounting frame 2, a pressing plate 4 being connected to the first electric push rod 3, a material sensor 5 being embedded in the lower wall of the pressing plate 4, the material sensor 5 being a device well known to persons skilled in the art, the specific model and principle of which will not be described in detail herein, a top plate 6 being mounted on the end of the pressing plate 4 away from the material sensor 5;

[0015] The first electric push rod 3 pushes the pressing plate 4 downward, thereby causing the top plate 6 to move downward, so that the top plate 6 is close to the discharge conveyor belt 1 but does not touch it, and the top plate 6 blocks the passage of materials;

[0016] Clamping plates 7 are symmetrically arranged in the front and rear of the mounting frame 2, and second electric push rods 8 are arranged on the clamping plates 7. The second electric push rods 8 are installed on the side walls of the mounting frame 2. Contact sensors 9 are embedded on the surfaces of the clamping plates 7 close to each other. The contact sensors 9 are well-known devices in the art, and the specific models and principles are not described in detail here.

[0017] The second electric push rod 8 can push the clamping plate 7 to move, and the clamping plate 7 is clamped at both ends of the material to correct the position of the material;

[0018] A plurality of rollers 10 are arranged on the lower wall of the pressing plate 4, and the rollers 10 are connected to the pressing plate 4 through a connecting structure, which includes a sleeve 11, and a connecting rod 12 is slidably arranged in the sleeve 11, and the connecting rod 12 is connected to the sleeve 11 through a spring 13, and the lower end of the connecting rod 12 slides through the sleeve 11, and the rollers 10 are installed on the corresponding connecting rods 12;

[0019] When the pressing plate 4 is pressed down, the roller 10 first presses on the upper wall of the material, and as the pressing plate 4 is gradually pressed down, the spring 13 is gradually compressed;

[0020] A sliding groove 14 is provided on the inner wall of the sleeve 11 , and a sliding block 15 is slidably arranged in the sliding groove 14 . The sliding block 15 is fixedly connected to the connecting rod 12 to prevent the connecting rod 12 from sliding out of the sleeve 11 .

[0022] Embodiment: When in use, the material is transported on the discharge conveyor belt 1, such as Figure 1 As shown, the material is transported from left to right. When the material passes through the material sensor 5, the material sensor 5 detects that the material has passed, and the controller controls the first electric push rod 3 to work, driving the pressure plate 4 to descend, thereby causing the top plate 6 to descend, so that the material is pressed against the top plate 6, and then the second electric push rod 8 is controlled to control the clamping plate 7 to approach the material, and the clamping plate 7 is corrected. After the material is corrected, both ends of the material contact the contact sensor 9, and the controller controls the second electric push rod 8 and the first electric push rod 3 to shrink.
