Description

Technical Field

[0001] This invention relates to the technical field of machining waste recycling devices, and in particular to a machining scrap processing equipment. Background Technology

[0002] Iron filings generated during production in machining workshops are typically collected by iron filing carts attached to the machine tools and then pushed to a designated area within the factory for storage. Once a certain amount has accumulated, they are loaded into transport vehicles manually or by loaders and transported away. However, this method of iron filings collection and disposal has the following problems:

[0003] 1. Piles of iron filings occupy a large area; 2. Residual cutting fluid in the iron filings drips onto the ground, causing environmental pollution; 3. Loading the piled iron filings into transport vehicles by hand or with a loader is labor-intensive and time-consuming.

[0004] Therefore, on June 15, 2015, our company applied for a patent entitled "A Centralized Processing Mechanism for Iron Scrap in a Machining Workshop," with patent number ZL201520409913.9, for the mechanized processing of iron scrap. However, the device in the patent still has the following problems:

[0005] 1. The iron filings storage box is composed of two symmetrical halves. Residual cutting fluid drips from the joint, polluting the environment. 2. A swing slide for guiding iron filings is installed under the conveyor belt inside the rain shelter. The swing rod connected to the swing slide is prone to bending and failure when the iron filings are tangled together. 3. When the conveyor belt transports the tangled iron filings, the iron filings roll like a snowball, getting bigger and bigger, eventually jamming the conveyor belt or damaging the guard plate.

[0006] Therefore, there is an urgent need for a chip handling device that can prevent residual cutting fluid from dripping onto the ground and prevent chip jamming on the conveyor belt during chip transport. Summary of the Invention

[0007] The purpose of this invention is to provide a machining chip processing device to solve the problems existing in the prior art, which can prevent cutting fluid from dripping onto the ground and prevent chips from getting stuck in the conveying device during the conveying process.

[0008] To achieve the above objectives, the present invention provides the following solution:

Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0052] The purpose of this invention is to provide a machining chip processing device to solve the problems existing in the prior art, which can prevent cutting fluid from dripping onto the ground and prevent chips from getting stuck in the conveying device during the conveying process.

[0053] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0054] This invention provides a machining chip processing device, see attached drawing. Figure 1 ~Appendix Figure 27As shown, the device includes a feeding trolley for conveying iron filings. The feeding trolley includes a support frame 14, with a support base plate at the bottom of the support frame 14. A trolley roller assembly 16 is installed at the bottom of the support base plate, and the trolley roller assembly 16 can roll on a moving guide rail, a conveying guide rail, or a horizontal storage guide rail. A receiver 15 is installed on the support base plate.

[0055] In a further preferred embodiment, the storage box body 30 includes a body crossbeam 34, a body longitudinal beam 38, and a body vertical beam 36 fixedly connected. A body longitudinal inner plate 39 is fixedly provided at the body longitudinal beam 38, and corresponding inner plates are provided at other beam positions, thus forming the storage box body. The bottom of the body vertical beam 36 is provided with a body inclined inner plate 37, which serves as the bottom opening of the storage box for sealing contact with the movable guard plate assembly. Storage box roller assemblies 35 are provided on the outer sides of both ends of the body crossbeam, which are rolled on the guide rails on the storage box support to facilitate the movement of the storage box. The movable guard plate assembly includes a guard plate crossbeam 41, a guard plate upper connecting beam 42, a guard plate inclined beam 43, and a guard plate lower connecting beam 44 fixedly connected in sequence. A guard plate inner plate 45 is provided on the inner side of the guard plate inclined beam 43, and a guard plate bottom plate is provided on the guard plate lower connecting beam 44. A guard plate roller assembly 40 is installed on the guard plate crossbeam 41 for sliding on the storage box guide rail.

[0056] Specifically, the lifting platform system includes a lifting platform support 28, a conveying support 3 horizontally positioned above one end of the lifting platform support 28, and a conveying guide rail on the conveying support 3; a lifting platform drive device 6 is mounted on the lifting platform support 28, and the lifting platform drive device 6 is connected to a horizontally arranged lifting platform assembly 8, which is used to hold the feeding trolley; a lifting roller assembly 52 is mounted on the lifting platform support for rolling connection with the lifting platform assembly 8. Figure 4 As shown, the lifting platform assembly 8 includes a platform 22. Lifting chain connectors 21 are symmetrically arranged at both ends of the platform 22. Platform roller assemblies 17 are installed on the outer side of the lifting chain connectors 21. Platform guide rails 18 are symmetrically arranged on the top of the platform 22. The feeding trolley can be rolled on the platform guide rails 18. A stop pin bracket 20 is fixed between the two platform guide rails 18. The height of the stop pin bracket 20 is less than the height between the bottom of the feeding trolley and the platform. A trolley stop pin device 19 is installed on the stop pin bracket 20. The trolley stop pin device 19 includes a stop pin cylinder. A stop pin is connected to the top of the stop pin cylinder. The stop pin can move upward to block the feeding trolley. The lifting platform drive device 6 is connected to the platform drive. The lifting platform drive device 6 includes a first lifting drive shaft 50 and a second lifting drive shaft 51 disposed on the top of the lifting platform. A sprocket is installed at one end of both the first lifting drive shaft 50 and the second lifting drive shaft 51. The two sprockets are connected by a first lifting drive chain 47. The first lifting drive shaft is connected to a lifting reducer 48 by a second lifting drive chain 49. The lifting reducer 48 is connected to a lifting motor. The first lifting drive shaft and the second lifting drive shaft are fixedly connected to the lifting chain connector 21 by a lifting chain 46.

[0057] To ensure the two feeding trolleys work together without interfering with each other, this embodiment includes a feeding trolley storage device. The feeding trolley storage device is located at the end of the lifting platform support away from the conveying support. The feeding trolley storage device includes a storage bracket coaxially arranged with the lifting platform. The storage bracket has a horizontal storage guide rail, and a column is located on one side of the horizontal storage guide rail. A trolley stop pin device is installed on the column. A movable guide rail assembly 27 is installed on the lifting platform support, such as... Figure 8 As shown, the movable guide rail assembly 27 is disposed on both sides of the line connecting the storage bracket and the conveying bracket. The movable guide rail assembly 27 includes a movable cylinder disposed on the lifting platform bracket. The end of the movable cylinder is connected to the movable guide rail 7, which can dock with the conveying guide rail.

[0058] The feeding trolley drive unit is located on one side of the conveying support and the storage support. The drive unit includes a first conveying drive shaft 55 located on one side of the storage support and a second conveying drive shaft 57 located on the same side of the conveying support. The first conveying drive shaft 55 is connected to a conveying reducer 53 via a conveying drive chain 54, and the reducer 53 is mounted on a base plate 61. The first and second conveying drive shafts are connected by a trolley drive chain 58, which is located within a drive chain slide rail 59. A guide rail 58 is provided between the first and second conveying drive shafts. A trolley guide rail 60 is provided, on which two push-pull trolleys 56 are movably mounted. A trolley drive chain 58 is connected to one side of each push-pull trolley 56, and both ends of the trolley drive chain 58 are connected to a first conveying drive shaft and a second conveying drive shaft. A push shaft 24 is fixedly mounted inside each push-pull trolley 56, which can push the feeding trolley to move horizontally on the conveying guide rail and the horizontal storage guide rail. To facilitate control of the feeding trolley's movement, in this embodiment, the track length of the feeding trolley drive device is greater than the distance between the end of the conveying guide rail near the storage box and the end of the horizontal storage guide rail away from the storage box, thus allowing the push-pull trolley to participate in controlling the horizontal movement of the feeding trolley throughout the entire process. The push-pull trolley includes a trolley body 25, which is movably mounted on the trolley guide rail via a trolley guide wheel assembly 23. One end of the trolley body 25 is connected to the trolley drive chain via a trolley chain connector 26. The push shaft 24 is fixedly and horizontally mounted on one side of the trolley body 25.

[0059] In operation, the lifting platform assembly is initially positioned below the lifting platform support 28. The second feeding trolley 9 is located on the guide rail of the lifting platform assembly. Four sets of trolley stop pin devices are installed on the lifting platform assembly. The stop pins extend to prevent the second feeding trolley 9 from rolling off the rail. At this time, the first feeding trolley 1 is located in the feeding trolley storage device. (See lifting platform assembly for details.) Figure 3 , Figure 4 .

[0060] Iron filings generated in the machining workshop are collected by the machine tool operator and poured into the U-shaped box of the second feeding trolley 9. When the U-shaped box is full of iron filings, the operator presses the control button, and the lifting motor, lifting reducer, lifting drive chain, lifting transmission shaft, and lifting chain on the lifting platform system begin to operate. The second feeding trolley 9, along with the lifting platform assembly, is lifted upwards to the preset position. The platform guide rail on the lifting platform assembly is then connected with the conveyor guide rail on the conveyor support. Figure 5 .

[0061] Subsequently, the proximity switch receives a signal, activating the trolley stop device on the lifting platform assembly and the feeding trolley storage device. The stop retracts, and simultaneously, an electrical signal is sent, initiating operation of the motor, reducer, conveyor drive chain, transmission shaft, and trolley drive chain of the feeding trolley drive unit. The push-pull trolley 56, connected to the trolley drive chain, moves to the right. (The last sentence appears to be incomplete and possibly refers to a different event or sequence.) Figure 6 Under the thrust of the push shaft 24 on the push-pull trolley 56, the first feeding trolley 1 moves to the right on the guide rail. After contacting and colliding with the second feeding trolley 9, it pushes the second feeding trolley 9 to move to the right together.

[0062] When the first feeding trolley 1 pushes the second feeding trolley 9 to the right and reaches the preset position, the first feeding trolley 1 is located on the platform guide rail 18 of the lifting platform assembly. This triggers the proximity switch, stopping the feeding trolley drive. The trolley stop pin on the lifting platform assembly extends, activating the lifting drive of the lifting platform system. The lifting platform assembly and the first feeding trolley 1 descend together, stopping at the preset position at the lower end of the lifting platform support. Simultaneously, the feeding trolley drive activates, and under the thrust of the push-pull trolley 56, the second feeding trolley 9 moves to the right. Upon reaching the right end of the conveying support, the feeding trolley drive stops, and the receiver installed under the second feeding trolley 9 automatically closes, connecting the circuit. The motor on the second feeding trolley 9 drives the reducer, causing the U-shaped box to flip and the iron filings inside to be poured into the storage box 4. Figure 7 The push-pull trolley is located outside the conveying support and will not interfere with the feeding trolley. The push-pull trolley relies on the horizontally extended push shaft to push the feeding trolley to move horizontally.

[0063] After the U-shaped box rotates to the preset position and stops, the iron filings are completely dumped. The motor and reducer on the second feeding trolley 9 drive the U-shaped box to rotate in the opposite direction and stop when it reaches the preset position. At the same time, a proximity switch is triggered, starting the feeding trolley drive device. Under the action of the push-pull trolley assembly, the second feeding trolley 9 moves to the left and starts the moving guide rail assembly 27. The moving guide rails on both sides of the moving guide rail assembly 27 move towards the middle simultaneously. When the moving guide rail on the moving guide rail assembly 27 aligns with the conveying guide rail on the conveying bracket, the moving guide rail assembly 27 stops. Figure 9The second feeding trolley 9, moving to the left, passes the moving guide rail on the moving guide rail assembly 27 and reaches the feeding trolley storage device at the left end. The feeding trolley drive device stops, and two stop pins in the feeding trolley storage device extend to block the second feeding trolley 9 at the left end of the support system, preventing it from rolling back to the right. After the feeding trolley drive device stops for a delay, it restarts, and the trolley drive chain carries the push-pull trolley to the right, stopping at a preset position, waiting for the first feeding trolley 1 located at the lower end of the lifting platform support to rise. Thus, the second feeding trolley 9 completes one work cycle.

[0064] When one end of storage box 4 is filled with iron filings, an electrical signal is triggered, and storage box 4 moves under the action of a hydraulic cylinder. Once it reaches a preset position, the hydraulic cylinder stops working, and the other end of storage box 4 awaits the iron filings to be poured in. (See...) Figure 10 , Figure 11 .

[0065] When the entire storage box 4 is full, the worker drives the scrap metal transport truck under the storage box 4, activates the control button, and the hydraulic cylinder for the liquid receiving tank 33 begins to operate. The piston rod extends, pushing the liquid receiving tank 33 to the right, away from the center position under the storage box 4. After reaching the position, an electrical signal is triggered, and the piston rod of the storage box opening and closing cylinder extends, pushing the movable guard plate assembly to the left. An opening appears under the storage box 4, and the scrap metal falls into the truck's cargo box. See Figure 12 , Figure 13 , Figure 14 , Figure 15 .

[0066] After the metal scrap is loaded, the operator presses the start button. The piston rod of the storage box opening and closing cylinder retracts, pulling the movable guard plate assembly to the right until it closes with the storage box body. Simultaneously, an electrical signal is triggered, and the fluid receiving tank moving cylinder starts working. The piston rod retracts, pulling the fluid receiving tank 33 to the left, reaching the middle position below the storage box 4. Residual cutting fluid from the metal scrap in the storage box 4 drips down, is collected, and flows into a recovery bucket through a water pipe. This completes one working cycle of the machining metal scrap processing equipment provided by this invention.
