[0017] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments so that those skilled in the art can implement the invention with reference to the description.
[0018] It should be understood that terms such as “having”, “including” and “comprising” used herein do not preclude the existence or addition of one or more other elements or combinations thereof.

They do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore should not be understood as limiting the present invention.
[0020] Example 1: Reference Figures 1-8 A feeding conveyor for filamentary materials for laser equipment includes a conveyor 1, a driving member 13 is installed on the side of one end of the conveyor 1, and a guide plate 12 is provided at one end of the conveyor 1. It also includes: a support block 11, which is arranged on the chain plate on the surface of the conveyor 1; a limiting roller 2, which is arranged above the conveyor 1, and the friction surface of the middle section is adapted to the support block 11; a cavity structure is provided inside the limiting roller 2, and when the driving member 13 drives the conveyor 1 to run, it drives the limiting roller 2 to run synchronously to convey the filamentary material conveyed on the conveyor 1; symmetrically distributed auxiliary rollers 37 are arranged between the limiting roller 2 and the support block 11, and are used to improve the stability of conveying the upper filamentary material.
[0021] The conveyor used in the prior art for conveying filamentary materials during laser processing is generally composed of a bracket, a driving unit, a chain and chain plate, a friction roller and other accessories. During the conveying process, although the friction contact parts are made of rubber material, they are prone to deformation after long-term contact and use, causing the friction contact materials to slip, deflect, etc., thereby causing instability of the conveyed filamentary materials and affecting the subsequent processing accuracy of the laser equipment. In this solution, the driving member 13 includes a driving source reduction motor. When in use, the driving source is turned on to drive the driving gear at the end of the reduction motor to rotate, and the rotating wheel 21 is connected to the driving gear through a synchronous belt drive, thereby driving the limiting roller 2 to rotate synchronously. After the driving member 13 is started, it drives the chain plate on the conveyor 1 to drive and operate, so that the support block 11 performs an elliptical operation on the conveyor 1, so that one end of the filamentary material passes through the limiting roller 2 and the support block 11. The limiting roller 2 and the support block 11 cooperate with each other to limit the penetrating filamentary material, and the friction generated when the limiting roller 2 and the support block 11 contact the surface of the filamentary material is used to drive the filamentary material to be transported on the conveyor 1, thereby realizing the transportation of the filamentary material. The limiting roller 2 is a hollow structure, and gas can be filled into the interior of the limiting roller 2 to make the middle section of the limiting roller 2 expand, thereby improving the limiting effect of the limiting roller 2 on the filamentary material and adapting to the material transportation of filamentary materials of different sizes. At the same time, the inflation can be used to correct the deformation of the friction contact part of the limiting roller 2 to reduce the occurrence of slippage and offset. The setting of the auxiliary roller 37 enables the surface of the filamentary material to obtain contact friction with objects all around during the transportation process, thereby increasing friction, improving the stability of the material transportation process, and improving the accuracy of the material in the subsequent processing process.
[0022] Example 2: Reference Figure 3 、 Figure 4 and Figure 7 , which is basically the same as Example 1, and furthermore, two ends of the limiting roller 2 are fixedly connected with a rotating shaft 22, one end of one of the rotating shafts 22 is fixedly mounted with a rotating wheel 21, the surface of the rotating wheel 21 is linked to the output end of the driving member 13 through a synchronous belt, the surfaces of the two rotating shafts 22 are rotatably connected with a support plate 23 through a bearing, the end of the support plate 23 is fixedly connected to the conveyor 1, one end of the limiting roller 2 is provided with an air inlet 28, and the air inlet 28 is provided with a valve, the middle section surface of the limiting roller 2 is provided with a concave surface 24, the surface of the concave surface 24 is provided with a convex film 25, the surfaces of both sides of the middle section of the limiting roller 2 are provided with inclined surfaces 26, the surface of the support block 11 is provided with an arcuate surface, the arcuate surface is adapted to the concave surface 24, and the support block 11 is made of flexible rubber material; Among them, the concave surface 24 is arranged in the middle section of the limiting roller 2, which is just adapted to the multiple support blocks 11 arranged below, so that the two arc surfaces are stuck on the upper and lower surfaces of the penetrating filamentary material, thereby realizing the limitation of the filamentary material during the conveying process. When the conveyor 1 is running, the support block 11 moves in a circle. At this time, the limiting roller 2 rotates synchronously, so that the friction force generated by the contact between the surface of the filamentary material and the surface of the limiting roller 2 and the support block 11 is used to drive the conveying operation of the penetrating filamentary material. There is no need to set a traction mechanism at the front end of the material conveying of the conveyor 1. The two arc surfaces can just play a certain auxiliary limiting effect on the penetrating filamentary material to prevent the material from deviating left and right during the conveying process. During the use of the device, the wear state of the friction contact part in the middle section of the limiting roller 2 can be observed. By injecting air into the interior of the limiting roller 2 through the air inlet 28, the raised membrane 25 is expanded, and the limiting degree of the limiting roller 2 is adjusted. At the same time, this flexible limiting structure has a better protection effect on the transported filamentous material than the traditional single rubber layer structure, and prevents the deformation and damage of the material caused by excessive limiting extrusion force.
[0023] It should be understood that the raised membrane 25 is made of a wear-resistant composite rubber material, one side of which is connected to the interior of the limiting roller 2, and two groups of raised membranes 25 are symmetrically arranged on the concave surface 24. When expanded, they have a certain clamping effect on the upper surface of the penetrating filamentary material, and are more stable for the transported filamentary material in the friction contact state.
[0024] Example 3: Reference Figure 5 、 Figure 6 and Figure 8 , which is basically the same as Example 2, and furthermore, a bevel gear 31 is fixedly mounted on the surface of the rotating shaft 22, and a matching gear 32 is meshed on the surface of the bevel gear 31, and a connecting shaft 33 is fixedly connected to the axis center of the matching gear 32, and the surface of the connecting shaft 33 is rotatably connected to the fixed block 4 through a bearing, one end of the fixed block 4 is fixedly connected to the support plate 23, and one end of the connecting shaft 33 is fixedly connected to a driving gear 34, and the surface of the driving gear 34 is connected to a driven gear 35 through a synchronous belt transmission, and the axis center of the driven gear 35 is fixedly connected to a rotating rod 36, an auxiliary roller 37 is fixed on the surface of the rotating rod 36, and the surface of the rotating rod 36 is rotatably connected to a support frame 38 through a bearing, and one end of the support frame 38 is fixedly connected to the support plate 23, and the surface of the auxiliary roller 37 is bonded with an anti-slip layer, which is made of flexible rubber material.
[0025] The above scheme is adopted, and what is further improved from the previous embodiment is that when the rotating shaft 22 rotates, the bevel gear 31 is also driven to rotate, and the bevel gear 31 is meshed with the mating gear 32 for transmission, so that the driving gear 34 and the driven gear 35 rotate synchronously, thereby driving the auxiliary roller 37 to rotate, so that the auxiliary support block 11 and the limiting roller 2 are in contact with the surface of the penetrating filamentary material, so that the surface of the filamentary material can be limited on all sides. In this way, the contact area with the surface of the filamentary material is effectively increased, and the material is prevented from slipping during the conveying process, thereby further improving the stability of the device in the material feeding and conveying process, and strengthening the limiting effect of the material to prevent the material from deviating left and right, so that the accuracy of the subsequent processing of the laser equipment is improved.
[0026] Example 4: Reference Figure 6 and Figure 8 , which is basically the same as Example 3, and furthermore, an extrusion block 51 is fixedly connected to the surface of the connecting shaft 33, an air bag 52 is provided on one side of the extrusion block 51, and the air bag 52 is installed on one side of the support plate 23, an air inlet pipe 53 is provided at one end of the air bag 52, and a valve is provided on the air inlet pipe 53, and an air supply pipe 54 is fixedly connected to one end of the air bag 52, and one end of the air supply pipe 54 passes through the support plate 23 and the fixed block 4 and extends to the outside where a nozzle is fixed, and a one-way valve 55 is provided on the nozzle head, and the nozzle head points to the inclined surface 26 provided on the surface of the limiting roller 2, and an air flow channel 27 is opened on the inner wall of the limiting roller 2, and the air holes at both ends of the air flow channel 27 are respectively located on the inclined surface 26 and the concave surface 24; Among them, the valve on the air inlet pipe 53 is a one-way valve. When the connecting shaft 33 rotates, it can also drive the extrusion block 51 to rotate synchronously. The extrusion block 51 is in the shape of a comma. When rotating, it contacts the airbag 52, extruding the airbag 52 to deform, so that the air inside the airbag 52 is squeezed and then ejected through the air pipe 54 for transportation. The nozzle is ejected and directed to the inclined surface 26 set on the limit roller 2. The inclined surface 26 guides the airflow, making it convenient for the airflow to pass through the airflow channel 27 and blow to the concave surface 24, making friction contact with the limit roller 2. The parts are cooled and blown to take away the heat, thereby reducing the deformation of the raised film 25, improving the service life of the device, avoiding malfunctions, reducing maintenance costs, and making the device have longer-term accuracy during transportation. Part of the airflow that has not passed through the air flow channel 27 can be blown to the auxiliary roller 37 and the support block 11 on the surface of the conveyor 1 to cool the auxiliary roller 37 and the support block 11. In addition, the airflow can also clean the dust and foreign matter remaining on the surface of the filamentous material in the conveying state under the blowing state, so that it has a certain cleaning effect.
[0027] It should be understood that, if necessary, a return spring can be provided in the airbag 52, and connecting plates are fixed at both ends of the return spring, and the connecting plates are fixed on the inner wall of the airbag 52. Through this structure, the smoothness of the airflow blowing is improved. In a preferred embodiment, the two extrusion blocks 51 are initially installed at different angles. When the extrusion block 51 on the left rotates to squeeze one of the airbags 52, the extrusion block 51 on the right does not contact the other airbag 52, and when the extrusion block 51 on the left is squeezed and contacted with the other airbag 52, the extrusion block 51 on the left does not contact one of the airbags 52. In this way, the airflow is continuously delivered to the friction area on the outer surface of the limiting roller 2, so as to achieve the purpose of continuous cooling and lowering the temperature, so that when the device conveys filamentous materials, the friction contact area provides better friction performance, so that the friction contact area generates Heat is quickly dissipated to reduce the occurrence of deformation. At the same time, this design scheme is adopted to avoid the friction contact parts, which causes foreign matter and dust to stick to the friction contact parts due to the inability to quickly dissipate heat, thereby reducing the adhesion of dust and foreign matter, and providing more stable endurance performance for materials in the friction conveying state. The air inlet end of the air inlet pipe 53 can be connected to the conveying cold air pipe, and one end of the cold air pipe is connected to the prepared cold air tank. When the gas transmission structure is running, the cold air in the air pipe can be extracted and then transported to the friction area to provide a better cooling effect. On the other hand, when the cold air blows to the surface of the limiting roller 2, since the limiting roller 2 is made of aluminum alloy material, it has a good thermal conductivity effect, which can assist in cooling the limiting roller 2 in the inflated state, and maintain the stability of the inflation of the limiting roller 2 to adjust the expansion of the raised membrane 25.
[0028] The above embodiments merely illustrate several implementations of the present invention, and while their descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patented invention. It should be noted that those skilled in the art would be able to make numerous variations and improvements without departing from the spirit of the present invention. These variations and improvements are equivalent modifications and improvements to the above embodiments based on the essential technology of the present invention and fall within the scope of protection of the present invention.
