Description

Technical Field

[0001] This utility model relates to the technical field of feeding devices, and in particular to a material feeding device. Background Technology

[0002] In an electroplating production line, the material feeding device automatically transfers the material storage cylinder from the storage station to the processing station, accurately positioning and delivering it to the corresponding station to ensure the continuous operation of the electroplating process. It needs to coordinate with the production line rhythm to complete operations such as workpiece gripping, posture adjustment, and smooth conveying, and is a core component for improving the automation level and operational efficiency of electroplating production.

[0003] However, existing material feeding devices are not convenient for controlling the amount of material fed during the feeding process, which can easily lead to overfeeding or underfeeding in a single feeding, making it difficult to accurately control the feeding amount and inconvenient to use. Utility Model Content

[0004] Therefore, the purpose of this utility model is to propose a material feeding device to solve the problems mentioned in the background art and overcome the shortcomings of the existing technology.

[0005] To achieve the above objectives, one embodiment of the present invention provides a material feeding device, including a feeding support bracket for support and guidance. A vibrating screen trough, driven by a vibrating cylinder and used for material conveying, is provided at the top of the feeding support bracket. A movable base for support is provided on one side of the vibrating screen trough. A motor-driven traveling trolley is provided at the top of the movable base. A pneumatic hopper, driven by a pneumatic system, is rotatably connected to the top of the traveling trolley. The pneumatic hopper is signal-connected to a PLC control system for control. The PLC control system is signal-connected to a pressure detection component for detecting the total amount of material being transferred. A discharge hopper is provided on one side of the pneumatic hopper at one end of the traveling trolley, and a lifting and movable material cylinder frame is provided on one side of the discharge hopper.

[0006] Preferably, in any of the above embodiments, the top of the feeding support is provided with a guide post for supporting the vibrating screen trough, the bottom of the vibrating screen trough has movable long slots at both ends that fit onto the surface of the guide post, the top of the vibrating screen trough is fixedly installed with a screening frame for guiding the material, the movable base is located on one side of the feeding support and fits against one side of the bottom of the feeding support, and the top of the movable base is provided with induction switches for positioning the traveling material trolley at both ends.

[0007] The above technical solution is adopted as follows: the top guide column of the feeding bracket (Q235 steel welding) provides vertical guidance for the vibrating screen trough. The movable long groove at the bottom of the vibrating screen trough fits into the guide column, allowing it to reciprocate along the guide column under the drive of the vibrating cylinder. The material is conveyed to one side by vibration. The top screening frame (stainless steel material) screens the material to avoid large pieces of material from clogging the subsequent structure. The movable base (cast iron material) fits against the bottom of the feeding bracket to form a continuous support surface. The top induction switch (infrared beam type) realizes the starting / ending point positioning of the moving material car by detecting the induction metal plate of the moving material car.

[0008] Preferably, in any of the above embodiments, the four corners of the bottom of the traveling material trolley are rotatably connected to traveling wheels that roll on the top surface of the movable base, and the two ends of the traveling material trolley are fixedly installed with rotating seats for support. The interior of the rotating seats is provided with connecting grooves for supporting the pneumatic hopper, and one end of the rotating seats is fixedly installed with an induction metal plate.

[0009] The above technical solution is adopted: the bottom travel wheels (polyurethane material) of the traveling trolley (aluminum alloy frame) roll on the top surface of the mobile base and are driven by the motor through chain transmission. The internal connecting grooves of the rotating seats at both ends cooperate with the rotating shaft of the pneumatic hopper to provide a rotation fulcrum. The sensing metal plate (stainless steel material) at one end of the rotating seat moves with the trolley. When it reaches the detection range of the induction switch, the switch sends a signal to the PLC to control the start and stop of the trolley and achieve precise positioning.

[0010] Preferably, in any of the above embodiments, the pneumatic hopper includes a pneumatic telescopic rod connected to the PLC control system signal, a transfer hopper for transferring materials, and a rotating bracket for supporting the transfer hopper. The pneumatic telescopic rod is rotatably connected to the interior of the rotating base, one end of the pneumatic telescopic rod is rotatably connected to the transfer hopper, and one end of the transfer hopper is fixedly installed with a rotating bracket that is rotatably connected to the movable base.

[0011] The above technical solution is adopted: the pneumatic telescopic rod is controlled by the PWM signal of the PLC control system. Its extension and retraction drive the transfer bucket (PP material) to rotate around the rotating bracket. In the initial state, the transfer bucket horizontally receives the material conveyed by the vibrating screen trough. When the pressure detection component detects the amount, the PLC controls the telescopic rod to extend, and the transfer bucket flips around the rotating bracket to pour the material into the lower feeding hopper. The rotating bracket (bearing connection) ensures that the transfer bucket rotates smoothly and avoids material spillage.

[0012] Preferably, in any of the above embodiments, the pressure detection component includes a pressure sensor connected to the PLC control system signal and a pressure plate that carries the material. The pressure sensor is fixedly installed inside the transfer hopper, and the detection end of the pressure sensor is fixedly installed with a pressure plate located inside the transfer hopper.

[0013] The above technical solution is adopted: a pressure plate (rubber material) covers the bottom of the transfer hopper. When receiving materials, the pressure is transmitted to the pressure sensor. The sensor transmits the pressure signal to the PLC control system. When the detected amount reaches the preset threshold, the PLC immediately sends a command to stop the vibration of the vibrating screen trough and at the same time controls the moving material car to move to the unloading station, so as to achieve precise control of the feeding amount.

[0014] Preferably, in any of the above embodiments, the hopper is fixedly installed at one end of the feeding car, the hopper is inclined downwards and positioned below the transfer hopper, and the bottom of the hopper has two discharge ports.

[0015] The above technical solution is adopted: the hopper (made of stainless steel) is fixed at one end of the traveling material car and tilted at a certain angle. Gravity is used to guide the material poured into the transfer hopper to the bottom. The double discharge port at the bottom can connect to the two material cylinders of the material cylinder frame at the same time, so as to realize the synchronous feeding of the two material cylinders and improve the feeding efficiency. The edge of the discharge port is rounded to avoid material retention.

[0016] Preferably, in any of the above solutions, the material cylinder frame is fixedly installed at one end of the movable base, and the inside of the material cylinder frame is provided with a lifting support that can be raised and lowered. The inside of the lifting support is provided with a material cylinder for storing materials, so that the discharge port of the hopper and the inlet position of the material cylinder correspond. When the hopper moves to one side of the material cylinder, the material is introduced into the inside of the material cylinder to complete the feeding. After the feeding is completed, the material cylinder is lifted to the middle of the material cylinder frame and the cover is locked.

[0017] The above technical solution is adopted: the internal lifting bracket of the material cylinder frame (aluminum alloy material) can drive the material cylinder to rise and fall. When feeding, the PLC controls the lifting bracket to fall so that the material cylinder inlet is aligned with the material hopper outlet. After feeding is completed, the bracket rises to the middle of the material cylinder frame, triggering the subsequent locking process. The locking structure between the lifting bracket and the material cylinder ensures that the material cylinder does not shake during the lifting process.

[0018] Compared with the prior art, the advantages and beneficial effects of this utility model are as follows:

[0019] 1. A pressure detection component is installed inside the pneumatic hopper for material transfer to weigh the total amount of material fed. Based on the amount of material detected by the pressure detection component, the vibrating screen trough, the traveling trolley, and the pneumatic hopper for conveying material are controlled. The vibrating screen conveying of material can be stopped when the amount of material fed reaches the threshold, and the transferred material is transferred to the material cylinder frame through the traveling trolley and the unloading hopper to realize the feeding of material. It can accurately detect the amount of material fed, avoid insufficient or excessive feeding in a single time, and improve the accuracy of feeding control and feeding efficiency.

[0020] 2. The pneumatic hopper can be rotated on top of the traveling trolley to adjust the state of the transported material, making it easier for the pneumatic hopper to hold and discharge the material, and for the traveling trolley to quickly transfer and load the material, thus improving the convenience of loading.

[0037] The above technical solution is adopted: the pneumatic telescopic rod 51 is controlled by the PWM signal of the PLC control system. Its extension and retraction drive the transfer bucket 52 (PP material) to rotate around the rotating bracket 53. In the initial state, the transfer bucket 52 horizontally receives the material conveyed by the vibrating screen trough.

[0041] The above technical solution is adopted: the feeding hopper 7 (made of stainless steel) is fixed at one end of the traveling material car and tilted at a certain angle. The material poured into the transfer hopper is guided to the bottom by gravity. The bottom double discharge port can connect to the two material cylinders of the material cylinder frame 8 at the same time, realizing synchronous feeding of the two material cylinders and improving feeding efficiency.
