Description

Technical Field

[0001] This utility model relates to a nut tapping machine, and in particular to a cooling oil filtration and recovery mechanism for a nut tapping machine. Background Technology

[0002] During the tapping process of a nut tapping machine, cooling oil is generally used to cool the tapping area. Simultaneously, the tapping debris also falls off along with the cooling oil. To conserve resources and reduce costs, the cooling oil is usually recycled, which necessitates filtration and recovery to remove debris. Current filtration and recovery mechanisms typically involve installing a filter screen in a collection tank. The cooling oil passes through the filter screen, while the debris is blocked. However, if the cooling oil directly passes through the first filter screen, the contact area between the oil and the first filter screen is relatively concentrated, causing debris to accumulate easily. This accumulation makes cleaning difficult as the cooling oil continues to pass through the first filter screen. Utility Model Content

[0003] This application provides a cooling oil filtration and recovery mechanism for a nut tapping machine, which can solve the problems mentioned in the background art.

[0004] This application provides a cooling oil filtration and recovery mechanism for a nut tapping machine, comprising:

[0005] The collection box has a first filter plate installed inside its wall, which divides the inner cavity of the collection box into an upper filtration chamber and a lower collection chamber; and has a first outlet communicating with the lower collection chamber.

[0006] The temporary storage box is installed in the middle of the first filter plate; gaps are left around it and between it and the walls of the collection box as filtration areas.

[0007] In some embodiments, the temporary storage box includes:

[0008] The outer casing is fixedly connected to the first filter screen plate at the bottom; the casing wall has multiple second outlets near the bottom.

[0009] The inner casing has an open bottom surface; it is detachably inserted into the outer casing; it is used to allow multiple second outlets to switch between being blocked and connected.

[0010] In some embodiments, both the outer and inner casings are cylindrical; the inner casing wall has multiple third outlets near the bottom; the multiple second outlets can switch between being blocked and connected in such a way that the multiple third outlets and the multiple second outlets switch between being in one-to-one correspondence and being staggered from each other.

[0011] In some embodiments, the first filter plate is higher on both sides and lower in the middle; the collection box is provided with a chip discharge port that communicates with the upper filter chamber, and the position of the chip discharge port corresponds to the higher side of the first filter plate.

[0012] In some implementations, a second filter plate is detachably connected to the inner casing wall.

[0013] In some implementations, the height of the inner box is greater than the height of the outer box, and the portion of the inner box that extends beyond the outer box is larger, so that there is a horizontal plane on the inner wall of the inner box; the connection position between the second filter plate and the inner box is on this horizontal plane.

[0014] In summary, this application discloses a cooling oil filtration and recovery mechanism for a nut tapping machine, comprising a collection tank and a temporary storage tank. Cooling oil first enters the temporary storage tank, and after filling it, overflows from an opening on the top surface, passing through a first filter plate and entering the lower collection tank. Some debris remains in the temporary storage tank, while some debris, along with the overflowing cooling oil, is blocked by the first filter plate in the upper filtration chamber. When the cooling oil directly passes through the first filter plate, the contact area between the cooling oil and the first filter plate is relatively concentrated, and debris in the cooling oil also concentrates at this location, making it prone to accumulation and requiring timely cleaning. By first filling the temporary storage tank and then overflowing from the opening on the top surface, the cooling oil is spread out on the first filter plate, resulting in a more dispersed contact area between the cooling oil and the first filter plate. This disperses the debris, making it less likely to accumulate, extending the cleaning cycle. Furthermore, cleaning is more convenient when the cooling oil continues to pass through the first filter plate. Attached Figure Description

[0027] Please see Figure 1 and Figure 2 A cooling oil filtration and recovery mechanism for a nut tapping machine includes a collection box 1 and a temporary storage box 2.

[0028] Based on the structure of the nut tapping machine, the collection box 1 is rectangular. A first filter plate 1-1 is installed inside the wall of the collection box 1, and correspondingly, the first filter plate 1-1 is rectangular. More specifically, first support bars 1a are welded to each of the four walls of the collection box 1, and the four edges of the first filter plate 1-1 are fixedly connected to these first support bars 1a. Through the first filter plate 1-1, the inner cavity of the collection box 1 is divided into an upper filtration chamber and a lower collection chamber. The upper filtration chamber is used to filter the cooling oil, blocking debris in the cooling oil, while the lower collection chamber is used to store the filtered cooling oil. The collection box 1 is also provided with a first outlet 1b connecting to the lower collection chamber, meaning the filtered cooling oil flows out through the first outlet 1b or is pumped out for recycling.

[0029] The temporary storage box 2 can be rectangular or cylindrical. It is installed in the middle of the first filter plate 1-1. More specifically, two second support bars 1c are fixedly connected between two opposing first support bars 1a, and the temporary storage box 2 is placed on the first filter plate 1-1 at the positions corresponding to the two second support bars 1c, supported by them. Spacing is provided around the temporary storage box 2 and between it and the walls of the collection box 1 as filtration areas.

[0030] Cooling oil first enters the temporary storage tank 2. After the temporary storage tank 2 is filled, it overflows from the opening on the top surface of the temporary storage tank 2 to the surrounding areas, passes through the first filter plate 1-1 and enters the lower collection tank 1. Some debris remains in the temporary storage tank 2, while some debris, along with the overflowing cooling oil, is blocked by the first filter plate 1-1 in the upper filter chamber.

[0031] Please see Figure 2 In some embodiments, the first filter plate 1-1 is higher on both sides and lower in the middle. The collection box 1 is provided with a chip discharge port 1d that communicates with the upper filter chamber, and the position of the chip discharge port 1d corresponds to the higher side of the first filter plate 1-1.

[0032] The debris blocked on the first filter plate 1-1 is swept to the side of the first filter plate 1-1 near the debris discharge port 1d by the rake. The debris on the first filter plate 1-1 can be cleaned more easily through the debris discharge port 1d.

[0033] Please see Figure 3 , Figure 4 , Figure 5 and Figure 6 In some embodiments, the temporary storage box 2 includes an outer box 2a and an inner box 2b. The bottom surface of the outer box 2a is fixedly connected to the first filter plate 1-1, and the two can be fixed by welding. The box wall of the outer box 2a has a plurality of second outlets 2a1 near the bottom surface. The bottom surface of the inner box 2b is open and can be detachably inserted into the outer box 2a, so that the plurality of second outlets 2a1 can be switched between being blocked and open through the inner box 2b.

[0034] The inner casing 2b blocks multiple second outlets 2a1, preventing the cooling oil entering the temporary storage tank 2 from flowing out of the second outlets 2a1. After the temporary storage tank 2 is full of cooling oil, it overflows from the opening on the top surface of the temporary storage tank 2, passing through the first filter plate 1-1 and entering the lower collection tank 1. After a period of time, the multiple second outlets 2a1 are switched to connect to the temporary storage tank 2. The cooling oil in the temporary storage tank 2 then flows out from the multiple second outlets 2a1, flushing the debris on the first filter plate 1-1 to the edge of the first filter plate 1-1, making it easier to clean.

[0035] Please see Figure 3 and Figure 4In some embodiments, based on the above embodiment of "the temporary storage box 2 includes an outer box 2a and an inner box 2b", the way in which the multiple second outlets 2a1 can switch between being blocked and connected can be: the inner box 2b is completely inserted into the outer box 2a, blocking the multiple second outlets 2a1; the inner box 2b is lifted upward a certain distance and held, and the multiple second outlets 2a1 are connected to the temporary storage box 2.

[0036] Please see Figure 5 and Figure 6 In some embodiments, based on the above-described embodiment where "the temporary storage box 2 includes an outer box 2a and an inner box 2b", both the outer box 2a and the inner box 2b must be cylindrical, and the inner box 2b has multiple third outlets 2b1 near its bottom surface on its wall. The multiple second outlets 2a1 can switch between being blocked and open in another manner: the multiple third outlets 2b1 and the multiple second outlets 2a1 can switch between one-to-one correspondence and mutual offset. That is, this is achieved by rotating the inner box 2b.

[0037] In some embodiments, based on the above-described embodiment where "the temporary storage box 2 includes an outer box 2a and an inner box 2b", a second filter plate 2-1 is detachably connected to the wall of the inner box 2b. More specifically, the two can be connected by magnetic attraction.

[0038] By switching the multiple second outlets 2a1 to connect to the temporary storage tank 2, as the cooling oil in the temporary storage tank 2 flows out from the multiple second outlets 2a1, debris in the cooling oil in the temporary storage tank 2 is blocked on the second filter plate 2-1. Compared to the cooling oil flowing out from the multiple second outlets 2a1 and then being blocked on the first filter plate 1-1, these debris are blocked on the second filter plate 2-1, and cleaning can be completed by replacing the second filter plate 2-1, making cleaning much more convenient.

[0039] Please see Figure 7 In some embodiments, based on the above embodiment where "the inner box 2b has a second filter plate 2-1 detachably connected to its wall", the portion of the inner box 2b that extends beyond the outer box 2a is larger, so that there is a horizontal plane 2b2 on the inner wall of the inner box 2b, and the connection position between the second filter plate 2-1 and the inner box 2b is on this horizontal plane 2b2.
