Description

Technical Field

[0001] This invention relates to the technical field of metal shavings processing equipment, specifically to an automatic aluminum shavings extrusion molding equipment. Background Technology

[0002] In the machining field, the use of machine tools for material removal inevitably generates waste chips. For routine small-batch parts processing, the waste chip generation is slow and the quantity is small, and ordinary collection and packaging methods can fully meet the waste chip disposal needs. However, in aluminum alloy sheet production lines, most of the finished or semi-finished aluminum sheets coming off the production line need to be sawed by precision saws, resulting in a large amount of sawdust. This aluminum chip must be processed in a timely manner to ensure the normal operation of the entire production line.

[0003] Therefore, aluminum shavings extrusion equipment has been developed. Currently, there are many aluminum shavings extrusion devices available, such as the one with patent number 202210012455.X, entitled "A Novel Fully Automatic Shavings Pressing Rod Equipment." This equipment includes a waste hopper, a pre-compression mold, an extrusion cylinder, and a forming mold. The waste hopper is connected to a material cavity, and a feeding auger is installed at the bottom of the waste hopper. The pre-compression mold is connected to the pre-compression cylinder. An extrusion mold rod, push rod I, and push rod II are fixedly connected to the piston rod of the extrusion cylinder. The forming mold has two forming cavities, A and B, driven by a mold-changing cylinder, allowing it to switch between left and right positions. When the forming mold is in the left or right position, the extrusion mold rod can enter cavity A or cavity B of the forming mold. This invention can automatically compress machining waste into high-density blocks of a specified size, thus facilitating waste collection and reuse. However, this structure has the following problems:

[0004] 1. During feeding, the feed inlet is not equipped with a power source, resulting in low feeding efficiency. Moreover, due to excessive material feeding, the feed inlet is prone to blockage. Therefore, the amount of material fed at one time cannot be too much, resulting in low efficiency.

[0005] 2. During the processing, the emulsified oil and aluminum shavings mix together and automatically fall into a container, which is inconvenient to separate and reuse. The collection and treatment process will seriously pollute the environment, so improvement is needed. Summary of the Invention

[0006] The purpose of this invention is to provide an automatic aluminum shavings extrusion molding device to solve the problems mentioned in the background art, such as the lack of a power source at the feed inlet during feeding, resulting in low feeding efficiency, and the tendency for the feed inlet to become clogged due to excessive material, thus limiting the amount of material fed at one time and leading to low efficiency; and the mixing of emulsified oil and aluminum shavings during processing, which automatically fall into a container, making separation and reuse inconvenient and causing serious environmental pollution during collection and treatment.

[0036] Example 1

[0037] Please see Figures 1-8As shown, this embodiment provides an automatic aluminum shavings extrusion molding equipment, including a cabinet 1, an extrusion assembly 2 housed within the cabinet 1, and a control cabinet 3 that controls the electrical operation of the entire equipment. A discharge port 4 is provided on the side of the cabinet 1, and an inclined discharge channel 4-1 is provided within the discharge port 4. An upper partition 5 is provided inside the cabinet 1, dividing the cabinet 1 into upper and lower areas. The pressurizing assembly is installed on the upper partition 5. An inlet 6 is provided on the cabinet 1, and a protective cover 7 is hinged to the inlet 6. A [missing information - likely a device or component] is provided inside the inlet 6. A funnel-shaped feeding hopper 8 has a discharge port at its bottom. A pushing component 9 is located on one side of the funnel-shaped feeding hopper 8 to compress the poured aluminum shavings into the discharge port. A stirring component 10 is located on the other side of the funnel-shaped feeding hopper 8 to agitate and disperse the aluminum shavings. The stirring component 10 and the pushing component 9 are symmetrically arranged. A discharge channel 11 is provided on the upper partition 5 to discharge the aluminum blocks from the extrusion component 2. A section is located inside the cabinet 1 below the upper partition 5. An oil recovery filtration device for recovering emulsified oil includes a filter box 12 located directly below a feeding channel 11, a second cylinder 13, a pusher plate 14, an oil receiving funnel 15, and an oil storage tank 16. The filter box 12 has openings at the top and bottom. A first filter mesh plate 17 is fitted over the top of the filter box 12. The lower opening of the filter box 12 is connected to the upper end of the oil receiving funnel 15. A second filter mesh plate 18 is installed at the lower end of the oil receiving funnel 15. The pore size of the second filter mesh plate 18 is smaller than that of the first filter mesh plate 16. The filter mesh plate 17 is described above. An oil inlet pipe 19 is provided below the filter mesh plate 18. The other end of the oil inlet pipe 19 is connected to the oil storage tank 16. The oil storage tank 16 is provided with an oil return port 20 located above the oil inlet pipe 19. A slag discharge port 21 is provided on the side below the oil storage tank 16. The second cylinder 13 is fixed on the pusher platform 22. The pusher platform 22 is fixed inside the cabinet 1. The piston rod of the second cylinder 13 is connected to a pusher plate 14 that pushes the aluminum blocks on the filter mesh plate 17 into the inclined discharge channel 4-1.

[0038] Preferably, to improve stirring and quickly push aluminum chips into the feed inlet, thereby increasing processing efficiency, the pushing assembly 9 includes a pushing cylinder 901 and a dovetail extrusion plate 902. The pushing cylinder 901 is fixed inside the cabinet 1, and an arc-shaped pushing rod 903 is connected to the output shaft of the pushing cylinder 901. The dovetail extrusion plate 902 is provided at the other end of the pushing rod 903. During operation, when it is necessary to push aluminum chips into the feed inlet, the pushing cylinder 901 operates, driving the dovetail extrusion plate 902 from the feed inlet. Figure 3The vertical position is changed to a horizontal position, which pushes the aluminum chips into the lower feed port, improving the rapid feeding effect; the stirring component 10 includes a stirring motor 101 and a stirring plate 102. The stirring motor 101 is fixed in the cabinet 1, and the output shaft of the stirring motor 101 passes through the funnel-shaped feed hopper 8 and is connected to the stirring plate 102. The stirring plate 102 is arranged parallel to the side of the funnel-shaped feed hopper 8. One or more stirring cone claws 103 are arranged in a ring on the stirring plate 102. During operation, the stirring component 10 first stirs the aluminum chips in the funnel-shaped feed hopper 8 to realize the stirring and dispersing of the clumps of aluminum chips. The stirring motor 101 drives the stirring plate 102 to rotate. Since the stirring plate 102 is equipped with multiple stirring cone claws 103, the stirring cone claws 103 can be inserted into the aluminum chips in front.

[0039] Preferably, the front end of the cabinet 1 is hinged with two cabinet doors 25. Each cabinet door 25 is provided with an operating handle 26 and a heat dissipation hole 27. The cabinet 1 is also provided with an LCD screen 28 electrically connected to the control cabinet 3, a main start switch 29, a cooling fan 30, a fan switch 31, an emergency stop button 32, a fault status indicator 33, and a working status indicator 34. Two hinge seats 35 are symmetrically arranged on both sides of the funnel-shaped feed hopper 8. A pneumatic rod 36 is hinged to each hinge seat 35. The piston end of each pneumatic rod 36 is hinged to the inner side of the protective cover 7, and the pneumatic rod 36 is electrically connected to the control cabinet 3. When it is necessary to open the protective cover 7 during operation, the pneumatic rod 36 is driven to operate, and the protective cover 7 is opened.

[0040] Preferably, to prevent aluminum blocks from falling out during transport, two parallel baffle plates 37 are provided at both ends of the filter mesh plate 17. The pusher platform 22 is located on the left side of the filter mesh plate 17, and the inclined discharge channel 4-1 is located on the right side of the filter mesh plate 17. By setting the baffle plates 37, the problem of aluminum blocks falling out from the front and back of the filter mesh plate 17 when they fall into the filter mesh plate 17 from the discharge channel 11 is prevented.

[0041] The specific working principle of this invention is as follows:

[0042] Open the protective cover 7 and pour the aluminum shavings into the funnel-shaped feed hopper 8. First, the stirring component 10 breaks up the clumps of aluminum shavings. Then, the driving component 9 works to press the broken aluminum shavings into the discharge port. Since the extrusion component 2 is located below the discharge port, the extrusion component 2 presses the aluminum shavings into aluminum blocks, which then fall into the filter box 12 from below the discharge channel 11. The filter mesh plate 17 first filters out larger impurities. Then, the second cylinder 13 is driven to work. As the material is processed, the pusher plate 14 moves towards the filter grid plate 17, pushing the aluminum block above into the inclined discharge channel 4-1, and finally outputting it from the discharge port 4. At the same time, oil and excess aluminum shavings fall from the filter grid plate 17 into the filter grid plate 2 18 for further filtration, leaving small aluminum shavings on the filter grid plate 2 18. Meanwhile, the oil is filtered into the oil receiving funnel 15 and transported to the oil storage tank 16 through the oil receiving pipe 19, where it settles and removes small amounts of aluminum shavings. Impurities settle at the bottom, while oil settles at the top. Because the oil storage tank 16 has a slag discharge port 21, slag can be discharged later. Simultaneously, the upper oil return port 20 can connect to the emulsified oil storage liquid in the extrusion assembly 2 to achieve oil recovery. It should be noted that the extrusion assembly 2 mainly includes a screw, a screw motor that drives the screw to rotate, an extrusion cylinder, an extrusion die, a feeding cylinder, and a feeding pusher, etc. During operation, the screw motor drives the screw to rotate, conveying the aluminum chips from the feeding port to the outlet, where they fall into the forming cavity. Then, the extrusion cylinder drives the extrusion die to press the aluminum chips into aluminum blocks within the forming cavity. After extrusion, the feeding cylinder drives the feeding pusher downwards to extrude the aluminum blocks from the forming cavity, which then fall through the feeding channel 11. It should be noted that the extrusion assembly 2 is conventional technology in this field and will not be described in detail. Therefore, this invention has the following technical effects:

[0043] 4. The present invention provides a stirring component 10 at the feeding point to stir and disperse the agglomerated aluminum chips, thereby preventing the agglomerated chips from affecting the funnel-shaped feeding hopper 8 and thus affecting the feeding, and further improving work efficiency.

[0044] 5. The present invention also provides a pushing component 9 at the feeding point to push the broken aluminum chips into the discharge port, thereby improving the feeding effect and further improving work efficiency;

[0045] 6. The present invention also adds an oil recovery and filtration device to realize the return oil filtration and reuse, thereby avoiding oil waste and environmental pollution.

[0046] Example 2

[0047] Please see Figure 9As shown, the general structure of the automatic aluminum shavings extrusion molding equipment provided in this embodiment is the same as that in Embodiment 1. The difference is that, as a preferred embodiment, to improve the safety of use, a pressure rod 38 is provided on the inner side of the protective cover 7, and a relay 39 cooperating with the pressure rod 38 is provided on the upper surface of the feed inlet 6. The relay 39 is electrically connected to the control cabinet 3, and when the relay 39 is pressed down by the pressure rod 38, the coil on the relay 39 is energized, causing the normally open contact on the relay 39 to close, and the control cabinet 3 controls the operation of the entire equipment. In this embodiment, by providing a pressure rod 38 on the inner side of the protective cover 7 and cooperating with the relay 39 at the corresponding position of the feed inlet 6, the equipment can only be controlled to work after the control cabinet 3 receives the signal from the relay 39 when the protective cover 7 is closed and the pressure rod 38 is pressed down to trigger the relay 39. This further improves safety and solves the problem that when the protective cover 7 is not closed, the equipment is working while the equipment is feeding materials, and the operator's hand may be accidentally injured by the pushing component 9 or the stirring component 10.

[0048] Example 3

[0049] Please see Figures 10-11 As shown, the general structure of the automatic aluminum shavings extrusion molding equipment provided in this embodiment is the same as that in Embodiment 1. The difference is that, preferably, manual material handling is not required, thus improving work efficiency. A ramp-type feeding and conveying assembly 40 is provided on the outside of the discharge port 4. The ramp-type feeding and conveying assembly 40 includes a horizontal section 401, a ramp section 402, and a closed-loop conveyor belt 403. One side of the horizontal section 401 is connected to the lower end of the ramp section 402, and a notch 404 is provided at the upper end of the ramp section 402. The horizontal section 401 is located below the discharge port 4. One end of the closed-loop conveyor belt 403 is fitted with a driven shaft 405, which is rotatably connected to the horizontal section 401. The other end of the closed-loop conveyor belt 403 is fitted with a main drive shaft 406, which is rotatably connected to the ramp section 401. At the high end of the ramp section 402, one end of the main drive shaft 406 passes through the ramp section 402 and is connected to the driven wheel 407. A positioning plate 408 is fixed on the side of the ramp section 402, and a drive motor 409 is fixed on one side of the positioning plate 408. The output shaft of the drive motor 409 is connected to the main drive wheel 410. A drive belt 411 is fitted between the main drive wheel 410 and the driven wheel 407. In this embodiment, to prevent the aluminum block from falling out of the other side of the horizontal section 401 when it is transferred from the discharge port 4 to the horizontal section 401, a baffle plate 412 is provided at the other end of the horizontal section 401. By setting the baffle plate 412, the aluminum block can be prevented from falling out of the side of the horizontal section 401, and safety can be improved. A protective cover 413 is fitted on the top of the ramp section 402 to improve safety.

[0050] The specific working principle of this embodiment is as follows: The inclined feeding and conveying assembly 40 is placed outside the discharge port 4, and the horizontal section 401 is located below the discharge port 4. During operation, a recycling basket is placed below the gap 404 of the inclined section 402. The processed aluminum block is started by the drive motor 409. Under the action of gravity, the aluminum block falls into the discharge port 4 and into the horizontal section 401. Then, driven by the drive motor 409, the main drive wheel 410 rotates first. Under the action of the drive belt 411, the driven wheel 407 rotates. The rotation synchronously drives the main drive shaft 406 to rotate. Since the two ends of the closed-loop conveyor belt 403 are tensioned between the main drive shaft 406 and the driven shaft 405, the rotation of the main drive shaft 406 drives the closed-loop conveyor belt 403 to rotate, transporting the aluminum blocks on the lower horizontal section 401 to the gap 404 position of the climbing section 402. Under the action of the closed-loop conveyor belt 403, the aluminum blocks fall from the gap 404 into the recycling basket below, achieving the effect of rapid recycling of the aluminum blocks. Later, the aluminum blocks need to be manually removed from the discharge port 4.

[0051] Preferably, the inclined feeding conveyor assembly 40 can be placed independently or directly fixed to the corresponding position on one side of the cabinet 1. In this embodiment, the inclined feeding conveyor assembly 40 can be separated from the cabinet 1 and placed independently. If it is necessary to fix the inclined feeding conveyor assembly 40 to the cabinet 1 later, the side plate of the horizontal section 401 can be threaded together with the side of the cabinet 1 by screws and sold as a complete set of products.

A pull-out cabinet 24 is provided in the square frame 23. The filter mesh plate 2 18 is provided in the pull-out cabinet 24. In this embodiment, the filter mesh plate 2 18 adopts a pull-out structure, which facilitates the later cleaning of the filter mesh plate 2 18. It is only necessary to open the cabinet door 25 to expose the pull-out cabinet 24, pull out the pull-out cabinet 24, and the aluminum shavings stored on the filter mesh plate 2 18 can be recycled and the filter mesh plate 2 18 can be cleaned.
