Description

Technical Field

[0001] This utility model relates to the field of die-cutting machine technology, specifically to a waste cleaning device for die-cutting machines. Background Technology

[0002] A die-cutting machine is a device that uses die-cutting rollers with specific circumferential shapes to transport cardboard through the rollers, and then uses the rollers to press and shape notches and holes of corresponding shapes on the surface of the cardboard.

[0003] Before the existing cardboard is rolled off the die-cutting roller, it is embedded in the die plate on the surface of the die-cutting roller. As the cardboard is removed from the die-cutting roller, it is usually carried by the die-cutting roller to continue to a higher position. Under the action of the conveyor belt, it is finally thrown out of the die-cutting machine by the die-cutting roller. To ensure that the cardboard can fall exactly on the vibrating conveyor belt and be cleaned up, the existing die-cutting machine usually installs an elastic soft iron strip on the vibrating conveyor belt. The bending arc of the soft iron strip makes the thrown cardboard hit the surface of the soft plate and fall onto the vibrating conveyor belt as soon as possible, so as to achieve stable transmission of the conveyor belt.

[0004] However, in actual production, it was found that some waste material still connected to the cardboard would fall back onto the surface of the cardboard. This caused the cardboard to be easily trapped between the cardboard pieces when collecting the cardboard after waste removal, resulting in an unstable structure when the cardboard was stacked and making it easy for the upper cardboard to slip off.

[0007] The present invention is further configured such that: the waste removal component has a closed-loop elongated oval structure, and the two ends of the waste removal component are fixedly provided with connecting rods for connecting with the tensioning assembly, and the frame is fixedly provided with limiting strips to guide the movement of the waste removal component.

[0008] The present invention is further configured such that: the tensioning assembly includes a pair of driving members arranged on both sides of the waste removal component, the driving members are connected to the frame, and the driving members guide several connecting rods to move away from the tensioning assembly until the connecting rods reach their limit of movement, at which point the driving members and the several connecting rods quickly separate.

[0009] The utility model further sets up: drive piece is air cylinder, one end of air cylinder is fixedly connected with frame, the other end of air cylinder can support a plurality of connecting rod activity.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. In the description of the present utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing the present utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] A waste cleaning device for a die-cutting machine, such as Figures 1 to 4 As shown, the device includes a frame 1, a conveyor belt 2 and several soft iron bars 3 hanging on the conveyor belt 2, several waste removal components 4 are arranged around the soft iron bars 3 and close to the conveyor belt 2, an elastic component connected to the waste removal components 4 is provided on the frame 1, and a tensioning component is provided to apply a force to the waste removal components 4 so that the waste removal components 4 move against the outer surface of the soft iron bars 3. In order to allow the waste material falling between the conveyor belt 2 and the cardboard to fall out in time, the conveyor belt 2 in this application has several gaps set at intervals perpendicular to the direction of its material transmission.

[0022] The cardboard flying out of the die-cutting machine is guided by the soft iron strip 3 and falls onto the surface of the conveyor belt 2. Then, as the conveyor belt 2 is transported, it passes the position where the soft iron strip 3 and the conveyor belt 2 are close. During this process, the cardboard opens up the two and gradually passes through. During this process, some waste material on the cardboard is blocked by the soft iron strip 3 and is not transported with the cardboard. Another part of the waste material is quickly separated by the active action of the waste removal component 4. It is continuously blocked by the waste removal component 4 and does not move with the cardboard, thereby achieving a further separation effect between the cardboard and the waste material.

Both ends of the waste removal component 4 are fixedly provided with connecting rods 41 for connecting with the tensioning component. The frame 1 is fixedly provided with a limiting strip 12 to guide the movement of the waste removal component 4. That is, the waste removal component 4 will slide and rotate each time it comes into contact with the soft iron strip 3, so that the waste material can be more easily separated from the connecting cardboard by the lateral pushing action of the waste removal component 4, and the damage to the surface of the cardboard is smaller during separation.

[0024] like Figure 3 , Figure 4 as well as Figure 5As shown, wherein the tensioning assembly comprises a driving element arranged on both sides of the waste cleaning element 4, the driving element is connected with the rack 1, the driving element guides a plurality of connecting rods 41 to move away from the tensioning assembly, until the connecting rod 41 reaches the limit of movement, the driving element and the plurality of connecting rods 41 are quickly separated, the driving element is a cylinder 5, one end of the cylinder 5 is fixedly connected with the rack 1, the other end of the cylinder 5 can support the plurality of connecting rods 41 to move, the elastic assembly comprises a plurality of elastic belts 6, the rack 1 is fixedly provided with two horizontal rods 11, the elastic belt 6 is sleeved with the two horizontal rods 11 and passes through a plurality of waste cleaning elements 4, the cross section of the waste cleaning element 4 is in a circular shape, the waste cleaning element 4 slides and abuts against the inner surface of the elastic belt 6.
