For example, china patent discloses a chain plate type conveyor, and the application number is: 2018104838410, comprising a conveying mechanism, a flight assembly and a reversing element. The maintenance and replacement of the single chain plate are convenient, but the defect of the single chain plate is that a gap exists between the two chain plates, so that workpieces can fall into an automatic discharging mechanism to generate the risk of clamping stagnation. And the single chain plate can generate a large gap at the rotation position of the automatic discharging mechanism, so that the risk of material leakage is caused. In addition, the laser power of the existing laser cutting machine is higher and higher, and laser can strike the chain plate through a workpiece, so that the chain plate is deformed, damaged and the like.

Detailed Description
The following detailed description of the invention refers to the accompanying drawings and preferred embodiments.
As shown in fig. 1, a conveying device of an automatic discharging mechanism of a laser cutting machine comprises a chain 1, a connecting bracket 2, a chain plate 3 and a connecting bolt 4;
the chain selected in the invention is a double-pitch conveying roller chain, and the pitch P of the chain is selected according to the conveyed load condition. The structure of which is shown in figure 2. The chain includes chain rollers 11, chain guards 12 and a roller center shaft 13. The roller center shaft 13 of the chain is a customized product, which replaces a standard product pin shaft to connect the chain roller and the chain baffle and extends out for a certain length at the same time, so as to be connected with the connecting bracket 2 in fig. 1. The end of the central shaft of the roller is provided with a slot, and a retainer ring is used for positioning the connecting bracket 2 in figure 1 during installation.
The structure of the connecting bracket is shown in fig. 3, and the connecting bracket is composed of four parts, namely: a support plate 21, a connecting plate 22, a connecting shaft sleeve 23 and a rivet nut 24. The working principle is that the connecting bracket is connected with the extending section of the roller central shaft of the chain through two round holes on the supporting plate 21. The connecting bracket is connected with the chain plate through bolts by the connecting plate 22 and the rivet nuts 24 on the connecting plate. The connecting shaft sleeve 23 has the function of increasing the contact area between the connecting bracket and the extending section of the central shaft of the roller, so that the condition that the connecting bracket is worn by the central shaft of the roller can be reduced; secondly, can be as the spacer tube between the adjacent linking bridge, guarantee conveyor's stability. The connecting bracket adopts a metal plate welding process, so that compared with the stamping connection on the market at present, the connecting bracket can save high mould cost for enterprises with smaller production batches and reduce the production cost. The connection form is also beneficial to be adjusted according to the unused site conditions.
The cross section shape and important dimension of the chain plate are shown in figure 4, the inner radius of the steel pipes at the two ends of the chain plate is R, and the center distance of the two steel pipes is L. The design process of the link plate, i.e., the design principle of the dimension in fig. 4, is described below. The arrangement of the link plates is shown in fig. 5. Each chain plate is arranged at a position with left lower side and right higher side. The inner radius R of the steel pipe at the two ends of each chain plate is selected by comprehensively considering the height of the discharging mechanism and the outer diameter of the standard steel pipe. The invention sets the steel pipe at the left end of each chain plate and the chain roller in coaxial relation, as shown in figure 5, the center distance of the steel pipes at the lower parts of two adjacent chain plates is the pitch of the chain P. According to the figures of the drawings,. To this end, the link plate design shown in the drawings is completed. According to the design of the chain plate shown in fig. 5, two steel pipes at the joint of the two chain plates are always in a tangent state, and the tangent relation of the two steel pipes is not changed although the tangent point is changed along with the change of the angle of the chain. On the one hand, the automatic discharging device can ensure that no matter what angle is needed by the automatic discharging device, the chain plates of the automatic discharging device cannot generate gaps at any positions, so that the phenomenon of clamping stagnation caused by falling of workpieces between the two chain plates is prevented, and equipment is damaged. On the other hand, a large gap is not generated at the rotation position of the chain, so that the condition of material leakage is avoided. And the raised steel pipe at the joint of the two chain plates can also play a role of a scraping plate, and can better drive a workpiece to be discharged out of a laser cutting machine along the running direction of the automatic discharging device.
The chain plate designed by the invention can select different forming processes and materials according to different use scenes. When the automatic discharging work is carried out for the low-power laser cutting machine, a forming process of welding the chain plate by using carbon steel can be selected, and the structure is shown in figure 6. The link plate comprises two carbon steel pipes 31 and a carbon steel plate 32. And welding and forming the three parts according to the designed size by using a welding tool. The selection of the process can meet the requirements and greatly reduce the equipment cost. When the automatic discharging work is carried out for the high-power laser cutting machine, the forming process of the chain plate by using the extruded aluminum profile can be selected according to the section shape shown in fig. 4. Because aluminum belongs to high-reflectivity metal, and the link joint is a certain distance away from the cutting point, the link joint made of aluminum is not easy to be damaged by laser, and the service life of the automatic discharging mechanism is prolonged.
It should be noted that modifications and adaptations to the present invention may occur to one skilled in the art without departing from the principles of the present invention and are intended to be comprehended within the scope of the present invention.
