Description

Technical Field

[0001] This utility model relates to the field of rivet feeding technology, and specifically to a rivet feeding device. Background Technology

[0002] A rivet is a mechanical fastener used to permanently join two or more workpieces, typically made of metal (such as steel, aluminum, or copper). Its structure consists of a head and a shank. The shank is deformed at one end by hammering or pressing to form the rivet head at the other end, thus securing the workpiece. Riveting offers high strength, vibration resistance, and good sealing properties, and is widely used in aerospace, bridge construction, shipbuilding, construction, and machinery manufacturing. Based on shape and application, rivets can be classified into solid rivets, semi-hollow rivets, and blind rivets, and are an important alternative to traditional welding and bolting connections.

[0003] A document with publication number CN207726256U discloses a rivet feeding device, relating to the field of rivet feeding. This rivet feeding device includes an inspection door, a feeding port, a rivet assembly machine, a support panel, a CNC panel, a support column, a motor, and a feeding outlet. The inspection door has a rectangular surface and a rectangular cross-section, and its right side is movably connected to the support panel via a rotary bearing using a transition fit. The feeding port has a rectangular upper surface, wider at the top and narrower at the bottom, and its bottom end is movably connected to the upper end of the support panel using an interference fit. The rivet assembly machine has a rectangular cross-section and is located inside the support panel, also movably connected to the support panel using an interference fit. The advantages of this invention are that it has a feeding outlet, which connects to the upper equipment via a connection interface. The material entering through the feeding inlet is metal, and the duct is easy to clear. The addition of a supporting magnet allows the material to be quickly attracted out, resulting in fast feeding speed. This solves the problem of slow feeding and material blockage, preventing the machine from malfunctioning and becoming inefficient when blocked.

[0004] After production and processing, rivets are conveyed by a conveyor belt until they are collected inside a hopper. However, when rivets fall from the production line into the hopper, free fall and collision can cause wear or deformation of the plating, which may affect the subsequent performance of the rivets. Utility Model Content

[0005] The purpose of this invention is to provide a rivet feeding device that solves the problem that when rivets fall from the production line into the material bin, the free fall collision can cause wear or deformation of the plating, which may affect the subsequent performance of the rivets.

[0006] This utility model solves the above-mentioned technical problems through the following technical solution: This utility model includes: The discharge mechanism includes a conveyor belt for conveying rivets, two baffles disposed on the conveyor belt to prevent rivets from falling off, and a discharge trough disposed at the end of the conveyor belt for allowing rivets to slide down. The protective mechanism includes an adjusting component for adjusting the length of the discharge trough plate and a buffering component for cushioning the sliding rivets inside the discharge trough plate.

[0007] Preferably, the adjusting component includes a movable trough plate slidably mounted on the surface of the discharge trough plate, a fixed plate fixedly mounted on the bottom of the two discharge trough plates, a connecting plate fixedly mounted on the bottom of the two movable trough plates, a motor fixedly mounted on one side of the fixed plate, and a lead screw fixedly mounted on the output end of the motor for driving the two movable trough plates to move synchronously.

[0008] Preferably, the surface of the connecting plate is provided with a threaded hole for use with a lead screw, and the end of the lead screw passes through the threaded hole and is threadedly connected to it.

[0009] Preferably, a limiting groove is formed on the outer surface of the discharge trough plate, and a limiting slider is fixedly installed on the inner side of the movable trough plate to cooperate with the limiting groove. The limiting slider is slidably installed inside the limiting groove.

[0010] Preferably, the buffer component includes a fixed frame fixedly installed at the end of the movable slot plate, a connector fixedly installed on the fixed frame, a nozzle disposed at the end of the connector for cushioning the rivet with air blowing, an air guide pipe connecting the two connectors, an air intake pipe connecting the surface of the air guide pipe, and an adjusting valve adapted to be installed on the surface of the air intake pipe for controlling the airflow size.

[0011] Preferably, a collecting plate is fixedly installed on one side of the two baffles that are close to each other, the other end of the collecting plate is fixedly connected to the port of the discharge trough plate, and an arc plate is fixedly installed between the two discharge trough plates.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: by adjusting the cooperation between the adjusting component and the buffer component, the length of the discharge trough plate is adjusted, and the rivet slides down is buffered. This solves the problem that when traditional rivets fall from the production line into the material bucket, the free fall collision will cause the plating to wear or deform. This improves the protection effect of rivet discharge and avoids damage to the surface of the rivet, thus affecting its performance. Attached Figure Description

[0015] The above-mentioned and other technical features and advantages of this utility model will be described in more detail below with reference to the accompanying drawings.

[0016] This embodiment provides a technical solution: a rivet feeding device, such as... Figure 1-4 As shown, it includes: The material discharge mechanism 100 includes a conveyor belt 110 for conveying rivets, two baffles 120 disposed on the conveyor belt 110 to prevent rivets from falling off, and a material discharge trough 130 disposed at the end of the conveyor belt 110 for allowing rivets to slide down. The protective mechanism 200 includes an adjusting component 210 for adjusting the length of the discharge trough 130 and a buffering component 220 for buffering the sliding rivets inside the discharge trough 130.

[0017] The adjustment component 210 and the buffer component 220 are used to adjust the length of the discharge trough plate 130 and to buffer the rivet from sliding down. This solves the problem that when rivets fall from the production line into the material bucket, the free fall collision will cause the plating to wear or deform. This improves the protection effect of rivet discharge and avoids damage to the surface of the rivet, thus affecting its performance.

[0018] Specifically, the adjusting component 210 includes a movable trough plate 211 slidably mounted on the surface of the discharge trough plate 130, a fixed plate 212 fixedly mounted on the bottom of the two discharge trough plates 130, a connecting plate 213 fixedly mounted on the bottom of the two movable trough plates 211, a motor 214 fixedly mounted on one side of the fixed plate 212, and a lead screw 215 fixedly mounted on the output end of the motor 214 for driving the two movable trough plates 211 to move synchronously.

[0019] When arranging different types of rivets, the length of the rivet discharge slot plate 130 needs to be adjusted according to the type of rivet to change the sliding angle and length of the rivet. First, the motor 214 is started, and the lead screw 215 is driven to rotate under the action of the motor 214. The lead screw 215 drives the connecting plate 213 to move. Furthermore, the connecting plate 213 drives the two movable slot plates 211 to move synchronously, so that the movable slot plates 211 slide on the surface of the rivet discharge slot plate 130 to adjust the length of the rivet discharge slot plate 130 to accommodate the rivet discharge of different types.

[0020] Furthermore, the surface of the connecting plate 213 is provided with a threaded hole for use with the lead screw 215, and the end of the lead screw 215 passes through the threaded hole and is threadedly connected to it.

[0021] Preferably, a limiting groove 216 is provided on the outer surface of the discharge trough plate 130, and a limiting slider 217 for use with the limiting groove 216 is fixedly installed on the inner side of the movable trough plate 211. The limiting slider 217 is slidably installed inside the limiting groove 216.

[0022] The limiting slide 216 and the limiting slider 217 are used to limit the movable slot plate 211, improve the stability of the movable slot plate 211 during sliding, and prevent the material discharge slot plate 130 and the movable slot plate 211 from shifting and affecting the sliding of the rivet.

[0023] Furthermore, the buffer component 220 includes a fixed frame 221 fixedly installed at the end of the movable slot plate 211, a connector 222 fixedly installed on the fixed frame 221, a nozzle 223 disposed at the end of the connector 222 for cushioning the rivets by blowing air, an air guide pipe 224 connecting the two connectors 222, an air intake pipe 225 connected to the surface of the air guide pipe 224, and an adjusting valve 226 adapted to be installed on the surface of the air intake pipe 225 for controlling the airflow.

[0024] When the rivet slides down to the outlet end of the movable slot plate 211, the end of the air intake pipe 225 is connected to the external airflow device. The high-speed airflow is introduced into the interior of the connector 222 through the air intake pipe 225 and the air guide pipe 224, and then blown onto the sliding rivet through the nozzle 223. The high-speed airflow will buffer the rivet and reduce the sliding speed of the rivet, thereby avoiding the rivet sliding too fast and colliding with the inner wall of the box where the rivets are stored, which would damage the coating on the surface of the rivet and affect the subsequent service life of the rivet.

[0025] Furthermore, a collecting plate 140 is fixedly installed on one side of each of the two baffles 120, and the other end of the collecting plate 140 is fixedly connected to the port of the discharge trough plate 130. An arc plate 150 is fixedly installed between the two discharge trough plates 130.

[0026] The rivet is guided to the feed port of the discharge trough plate 130 by the cooperation between the collecting plate 140 and the arc plate 150, so as to prevent the rivet from falling off.

[0027] In use: When arranging different types of rivets, the length of the rivet discharge slot plate 130 needs to be adjusted according to the type of rivet to change the sliding angle and length of the rivet. First, start the motor 214. Under the action of the motor 214, drive the lead screw 215 to rotate. The lead screw 215 drives the connecting plate 213 to move. Furthermore, the connecting plate 213 drives the two movable slot plates 211 to move synchronously, so that the movable slot plates 211 slide on the surface of the rivet discharge slot plate 130 to adjust the length of the rivet discharge slot plate 130 to accommodate the arranging of different types of rivets. When the rivet slides down to the outlet end of the movable slot plate 211, the end of the air intake pipe 225 is connected to the external airflow device. The high-speed airflow is introduced into the interior of the connector 222 through the air intake pipe 225 and the air guide pipe 224, and then blown onto the sliding rivet through the nozzle 223. The high-speed airflow will buffer the rivet and reduce the sliding speed of the rivet, thereby preventing the rivet from sliding too fast.

[0028] In summary, by adjusting the cooperation between component 210 and buffer component 220, the length of the discharge trough plate 130 is adjusted, and the rivet sliding down is buffered. This solves the problem that when traditional rivets fall from the production line into the material bin, free fall collisions can cause plating wear or deformation. This improves the protective effect of rivet discharge and prevents damage to the rivet surface from affecting its performance.

[0029] The above description is merely a preferred embodiment of the present utility model and is illustrative rather than restrictive. Those skilled in the art will understand that many changes, modifications, and even equivalents can be made within the spirit and scope defined by the claims of the present utility model, all of which will fall within the protection scope of the present utility model.
