Description

Technical Field

[0001] The invention relates to a waste material recycling device, in particular to an automatic waste material recycling device. Background Art

[0002] Forging machines generate waste during blanking and stamping processes. The traditional way to collect waste is to drop the waste from the leaking hole into the waste area below. However, the leaking hole can usually only collect waste in the center of the machine tool workbench, while the waste around the workbench cannot fall into the leaking hole and can only accumulate on the machine tool workbench. When it accumulates to a certain extent, workers are assigned to collect the waste around the workbench regularly. The labor intensity of the workers is high, which also greatly wastes human resources, resulting in high production costs and the inability to achieve full automation. At the same time, when manually cleaning the waste around the workbench, in order to prevent production safety problems, the machine tool must be shut down, which affects production efficiency. Summary of the invention

[0003] Purpose of the invention: In view of the above problems, the purpose of the present invention is to provide an automated waste recycling device to achieve all-round and automated recycling of waste, save manpower and improve production efficiency.

[0004] Technical solution: An automated waste recycling device, comprising a waste hopper, a mounting seat, a cylinder, a flap, a first hydraulic oil circuit, a second hydraulic oil circuit, a hydraulic system, a sensor, and a PLC. The waste hopper is placed vertically and installed on one side of a machine tool base, the top surface of the waste hopper overlaps with the table top of the machine tool base, the overlapping surface of the machine tool base and the waste hopper is an inclined surface inclined toward the waste hopper, the sensor is installed on the edge of the inclined surface, the flap covers the top of the waste hopper and is rotatably connected to the top of the waste hopper so that the flap opening faces the machine tool base, one mounting seat is respectively provided on opposite sides of the waste hopper, the mounting seats are respectively fixed to the machine tool base, one cylinder is respectively provided on the two mounting seats, one end of the cylinder is connected to the corresponding mounting seat, and the other end is connected to the corresponding side of the flap, the first hydraulic oil circuit and the second hydraulic oil circuit are respectively connected to the cylinder and the hydraulic system, and the hydraulic system and the sensor are respectively connected to the PLC.

[0005] An oil cylinder is set on the left and right sides of the flap rotation direction to realize the automatic control of the flap lifting and lowering. The first hydraulic oil circuit and the second hydraulic oil circuit are the oil cylinder lifting oil circuit and the oil cylinder lowering oil circuit respectively. The movement stroke of the oil cylinder determines the opening and closing angle of the flap. When there is waste on the table of the machine tool base, the waste falls along the slope on the table. After the sensor senses that there is waste passing, it sends a signal to the PLC. The PLC receives the signal and sends a command to the hydraulic system to control the oil cylinder to lift the flap, and the waste on the table can enter the waste hopper for collection. After the waste passes, the sensor sends a signal to the PLC again. The PLC receives the signal and sends a command to the hydraulic system to control the oil cylinder to drop the flap, realizing the automatic collection of waste, which is convenient and quick.

[0006] Furthermore, the hydraulic system includes an oil tank, a filter, an electric pump, a one-way valve, and a solenoid valve connected in sequence, the solenoid valve is connected to the PLC, and the first hydraulic oil circuit and the second hydraulic oil circuit are respectively connected to the solenoid valve.

[0007] Optimally, the solenoid valve is a three-position, two-way solenoid valve.

[0008] A three-position two-way solenoid valve is used. When the cylinder needs to be disassembled, assembled or overhauled, the three-position two-way solenoid valve is moved to the middle position, and the excess hydraulic oil in the left and right cylinders will flow back to the tank, thereby relieving the pressure and ensuring personnel safety.

[0009] Furthermore, one end of the oil cylinder is connected to the mounting seat through a connecting piece 1, and the connecting piece 1 includes a connecting seat 1, a hexagonal bolt with a hole, a slotted nut 1, and a cotter pin 1. The connecting seat 1 is fixed to the upper surface of the mounting seat, and the hexagonal bolt with a hole is sequentially passed through the connecting seat 1 and one end of the oil cylinder and is fastened by the slotted nut 1, and the cotter pin 1 is sequentially inserted into the slotted nut 1 and the hexagonal bolt with a hole 1.

[0010] Furthermore, the other end of the oil cylinder is connected to the flap via a second connecting piece, and the second connecting piece includes a second connecting seat, two hexagonal bolts with holes, two slotted nuts, and two cotter pins. The second connecting seat is fixed to the side of the flap, and the two hexagonal bolts with holes are sequentially passed through the second connecting seat and the other end of the oil cylinder and fastened via the two slotted nuts, and the two cotter pins are sequentially inserted into the two slotted nuts and the two hexagonal bolts with holes.

[0011] Furthermore, the flap is connected to the waste hopper via a hinge.

[0012] The hinge connection ensures that the flap is securely connected to the waste hopper and can rotate freely.

[0013] Furthermore, the waste hopper includes an upper hopper, a lower hopper, and a buckle. The bottom surface of the upper hopper is provided with a lower flange, and the top surface of the lower hopper is provided with an upper flange matching the lower flange. The lower flange is attached to the upper flange and fixed by a plurality of fasteners arranged at intervals, so that the upper hopper and the lower hopper are connected into an integrated funnel shape. The buckle is fixed to one side surface of the lower hopper, and the buckle is fixed to the machine tool base.

[0014] The waste hopper is designed as a split structure of an upper hopper and a lower hopper, so that the transportation, installation and disassembly of the waste hopper can be carried out separately, which is more convenient and simple to maintain.

[0015] Furthermore, the mounting seat includes a supporting seat and a connecting block, one side of the supporting seat is fixed to the machine tool base via two spaced connecting blocks, and one end of the oil cylinder is fixed to the upper surface of the supporting seat.

[0016] Furthermore, a buffer plate is fixed to two opposite free ends of the flip cover respectively, and a limit plate is fixed below each buffer plate and on the waste hopper respectively, and the height of the buffer plate is greater than the distance between the buffer plate and the limit plate.

[0017] The cooperation of the buffer plate and the limit plate can buffer the flap, preventing the hydraulic system from malfunctioning, causing the oil cylinder to lift the flap and suddenly fall down, causing a loud noise and damaging the waste hopper.

[0018] Furthermore, one side edge of the top surface of the waste hopper close to the machine tool base is overlapped with the table top of the machine tool base through the overlap plate, and the opposite sides of the overlap plate are respectively connected to the edge of the top surface of the waste hopper and the inclined surface of the machine tool base.

[0019] Considering that the waste hopper is a sheet metal part, there will be deviations in the manufacturing and installation processes. Therefore, there may be a situation where the waste hopper cannot be completely overlapped with the table top of the machine tool base. The overlap plate solves the problem of the assembly gap between the waste hopper and the table top of the machine tool base, ensuring that the waste falls into the waste hopper smoothly.

[0020] Beneficial effect: Compared with the prior art, the advantages of the present invention are: by adding a hydraulic oil circuit and a control system, combined with the cooperation of the flap and the waste hopper, the waste on the table of the machine tool base can automatically fall into the waste hopper along the inclined surface on the table and be collected. The whole process is convenient and fast, saving manpower and improving production efficiency; the automatic falling and lifting of the flap makes the device more automated and can improve the cleanliness of the factory building. The whole device is very convenient to disassemble, assemble and maintain. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments. It should be understood that these embodiments are only used to illustrate the present invention and are not used to limit the scope of the present invention.

[0034] An automated waste recycling device, such as Figures 1 to 12 As shown, it includes a waste hopper 1, a mounting base 2, a cylinder 3, a flap 4, a first hydraulic oil circuit 5, a second hydraulic oil circuit 6, a hydraulic system 7, a sensor, a PLC, a connector 1 8, a connector 2 9, and a hinge 10.

[0035] The waste hopper 1 is placed vertically, and the waste hopper 1 includes an upper hopper 11, a lower hopper 12, and a buckle 13. The bottom surface of the upper hopper 11 is provided with a lower flange, and the top surface of the lower hopper 12 is provided with an upper flange matching the lower flange. The lower flange is attached to the upper flange and fixed by a plurality of fasteners arranged at intervals, so that the upper hopper 11 and the lower hopper 12 are connected to form an integral funnel shape. The buckle 13 is fixed to a side surface of the lower hopper 12, and the buckle 13 is fixed to the machine tool base 100, so that the waste hopper 1 is installed on one side of the machine tool base 100, and the top of the waste hopper 1 The overlapping surface is overlapped with the table top of the machine tool base 100, and the overlapping surface between the machine tool base 100 and the waste hopper 1 is an inclined surface inclined in the setting direction of the waste hopper 1. Considering that the waste hopper is a sheet metal part, there will be deviations in the manufacturing and installation processes. Therefore, there may be a situation where the waste hopper cannot be completely overlapped with the table top of the machine tool base. A overlapping plate 15 can be set between the waste hopper 1 and the table top of the machine tool base 100, and the opposite sides of the overlapping plate 15 are respectively connected to the edge of the top surface of the waste hopper 1 close to the machine tool base 100 and the inclined edge of the machine tool base 100.

[0036] The sensor is installed on the inclined edge of the machine tool base 100. The sensor can be a proximity sensor, a gravity sensor, an optical sensor, etc. The flip cover 4 covers the top of the waste hopper 1 and is rotatably connected to one side of the top of the waste hopper 1 through a hinge 10. The flip cover 4 opens toward the machine tool base 100. A mounting seat 2 is respectively provided on the opposite sides of the waste hopper 1. A cylinder 3 is respectively provided on the two mounting seats 2. The mounting seat 2 includes a support seat 21 and a connecting block 22. One side of the support seat 21 is fixed to the machine tool base 100 through two spaced connecting blocks 22. One end of the cylinder 3 is fixed to the upper surface of the support seat 21 through a connecting piece 8. The connecting piece 8 includes a connecting seat 81, a hexagonal bolt with a hole 82, a slotted nut 83, and a cotter pin 84. The connecting seat 81 is fixed to the upper surface of the support seat 21. The hexagonal bolt with a hole 82 is sequentially penetrated through the connecting seat 81 and one end of the cylinder 3 and fastened through the slotted nut 83. The cotter pin 84 is sequentially inserted into the opening The other end of the oil cylinder 3 is connected to the flap 4 through the connecting piece 29, which includes a connecting seat 291, a hexagonal bolt 292 with a hole, a slotted nut 293, and a split pin 294. The connecting seat 291 is fixed to the side of the flap 4. The hexagonal bolt 292 with a hole is sequentially inserted through the connecting seat 291 and the other end of the oil cylinder 3 and fastened through the slotted nut 293. The split pin 294 is sequentially inserted into the slotted nut 293 and the hexagonal bolt 292 with a hole. A buffer plate 41 is fixed to the two opposite free ends of the flap 4, and a limit plate 14 is fixed to the waste hopper 1 below each buffer plate 41. The height of the buffer plate 41 is greater than the distance between the buffer plate 41 and the limit plate 14.

[0037] The first hydraulic oil circuit 5 and the second hydraulic oil circuit 6 are respectively connected to the oil cylinder 3 and the hydraulic system 7. The hydraulic system 7 includes an oil tank 71, a filter 72, an electric pump 73, a one-way valve 74, and a solenoid valve 75 which are connected in sequence. The solenoid valve 75 is a three-position two-way solenoid valve. The first hydraulic oil circuit 5 and the second hydraulic oil circuit 6 are respectively connected to the solenoid valve 75. The sensor and the solenoid valve 75 are respectively connected to the PLC.

[0038] A cylinder is set on the left and right sides of the flap rotation direction to realize the automatic control of the flap lifting and lowering. The first hydraulic oil circuit and the second hydraulic oil circuit are the cylinder lifting oil circuit and the cylinder lowering oil circuit respectively. The movement stroke of the cylinder determines the opening and closing angle of the flap. Since the flap and the waste hopper are connected by hinges, the flap can rotate freely. The cylinder lowering oil circuit and the cylinder lifting oil circuit of the left and right cylinders are respectively connected in series to the three-position two-way solenoid valve. When the PLC does not receive the command, the three-position two-way solenoid valve is in the middle position, the two cylinders are synchronously stationary, and the flap is in a non-working state, that is, the waste hopper is dropped and capped.

[0039] When there is waste on the table of the machine tool base, the waste falls along the inclined surface on the table. After the sensor senses that there is waste passing through, it sends a signal to the PLC. The PLC receives the signal and sends a command to the hydraulic system. The three-position two-way solenoid valve moves to the left position, and the hydraulic oil passes through the oil tank filter, the electric pump, and the one-way valve and then enters the cylinder jacking oil circuit of the two cylinders. The cylinders move up synchronously. At this time, the flap is lifted, and the waste on the table of the machine tool base can enter the waste hopper and be collected; after the waste has passed, the sensor cannot sense the passage of the waste, and then sends a signal to the PLC again. The PLC receives the command to stop collecting waste, and the three-position two-way solenoid valve moves to the right position. The hydraulic oil passes through the oil tank filter, the electric pump, and the one-way valve and then enters the falling oil circuit of the two cylinders. The two cylinders move down synchronously. At this time, the flap is reset, and the waste on the table of the machine tool base stops entering the waste hopper, realizing automatic collection of waste, which is convenient and fast. No matter whether the three-position two-way solenoid valve is moved to the left or right position, the excess hydraulic oil on the pressure-free side of the two cylinders will flow back to the oil tank, ensuring the recycling of the hydraulic oil.

[0040] PCL can not only control the lowering and lifting movement of the oil cylinder through the three-position two-way solenoid valve, but also set the time when the three-position two-way solenoid valve is in the left position and the right position in the program to control the time of the oil cylinder lowering and lifting, thus achieving full automatic control. By using a three-position two-way solenoid valve instead of a two-position two-way solenoid valve, when the oil cylinder needs to be disassembled, assembled, or repaired, the three-position two-way solenoid valve can be moved to the middle position, and the excess hydraulic oil in the left and right oil cylinders will flow back to the oil tank, thereby releasing pressure and ensuring personnel safety.
