Description

Technical Field

[0001] This utility model relates to the field of screening technology, specifically to a sleeve discharge screening machine. Background Technology

[0002] After the steering sleeve is stamped into a finished product, it is discharged along with waste material, which consists of waste particles punched out from the central through-hole of the steering sleeve. However, currently, the steering sleeve products and waste material are mixed together and enter the material frame. Subsequently, the material frame is transferred to the screening area for further screening, which is a cumbersome and inefficient process. In addition, the steering sleeve is covered with oil, and after being placed in the material frame, the oil accumulates at the bottom of the frame, causing problems for the subsequent separation of the products at the bottom. Utility Model Content

[0003] The present invention aims to provide a casing discharge screening machine to solve the problem of low efficiency in separating existing steering sleeve products from waste materials.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] The casing discharge screening machine includes an inclined upper distribution box and a lower distribution box. The upper distribution box is fixed on the frame and has a partition plate inside, which divides the interior of the upper distribution box into a screening area and a storage area. The storage area is located at the bottom of the upper distribution box. The screening area is equipped with an upper screen, and the bottom of the screening area is also equipped with an upper discharge port corresponding to the lower distribution box. The lower distribution box is equipped with a lower screen, and an oil baffle is provided at the bottom of the lower distribution box.

[0006] Preferably, as an improvement, the screening area is further provided with reinforcing ribs, and the reinforcing ribs are in contact with the upper screen to support the screen; the bottom of the screening area at the lower end near the upper discharge port forms an upward rolled edge on both sides, the rolled edge is close to the inner wall of the upper distribution box, and a reinforcing nail is provided at this location.

[0007] Preferably, as an improvement, the upper discharge port is a strip-shaped port, and the upper discharge port is located in the middle of the screening area or near the middle of the screening area; the reinforcing rib is located between the upper discharge port and the partition plate, and the reinforcing rib is located near the upper discharge port; an oil outlet is provided on the bottom surface of the upper distribution box near the partition plate; an oil outlet is also provided on the bottom surface of the lower distribution box near the lower end.

[0008] Preferably, as an improvement, the lowest point of the storage area is provided with an opening, the two sides of the opening are rolled to form a socket, a valve plate is inserted into the opening, and the two sides of the valve plate are inserted into the socket; a handle is also provided on the valve plate.

[0009] Preferably, as an improvement, it also includes a conveyor belt, a waste bin, and a product collection bin; the discharge end of the conveyor belt is located above the high end of the upper distribution bin, the product collection bin is located below the low end of the upper distribution bin, and the waste bin is located below the low end of the lower distribution bin.

[0010] Preferably, as an improvement, the oil outlet is connected to an oil guide pipe, and the oil guide pipe is connected to an oil tank.

[0011] Preferably, as an improvement, the lower end of the upper material distribution box is provided with a support frame, and the upper end of the upper material distribution box is fixedly connected to the frame of the conveyor belt.

[0012] The principles and advantages of this scheme are:

[0013] 1. This technology, through the combination of upper and lower material distribution boxes, not only reduces the floor space occupied, but also enables the simultaneous separation of steering sleeves, waste materials, and oil, greatly improving screening efficiency.

[0014] 2. The upper material box is divided into a screening area and a storage area. The screening area is longer than the storage area, which allows the falling steering sleeve, waste, and oil to have more time to separate as they slide toward the bottom storage area. In particular, the waste and oil have enough time to fall below the upper screen, ensuring the screening effect.

[0015] 3. This technology also incorporates reinforcing ribs below the upper screen. These ribs not only support and fix the upper screen but also, being positioned near the upper discharge port, act as baffles as waste particles roll down from the upper end to the upper discharge port, ensuring their proper discharge. The edges of the upper discharge port are rolled inwards to create a curled edge structure. This curled edge structure not only provides an inward guiding effect for the discharge but also allows for further fixation using reinforcing nails. Attached Figure Description

A conveyor belt 4 is also provided on one side of the upper distribution box 1, with the discharge end of the conveyor belt 4 corresponding to the high end of the upper distribution box 1, facilitating the dropping of sleeves on the conveyor belt 4 into the upper distribution box. A partition plate 11 is provided inside the upper distribution box 1 along the short side, dividing the interior of the upper distribution box 1 into a screening area 12 and a storage area 13. The screening area 12 is located at the high end of the upper distribution box 1, and the storage area 13 is located at the low end of the upper distribution box 1. In other embodiments besides this one, the high end of the upper distribution box 1 is welded and fixed to the frame.

[0023] The screening area 12 is provided with an upper screen 121. The bottom of the screening area 12, near the partition plate 11, is also provided with an upper discharge port 122 corresponding to the lower distribution box 2. The upper discharge port 122 is a strip-shaped opening and is located in the middle of the screening area 12 or near the middle of the screening area 12. A reinforcing rib 123 with an L-shaped cross-section is also provided between the upper discharge port 122 and the partition plate 11. The reinforcing rib 123 is located near the upper discharge port 122, and the bottom plate of the reinforcing rib 123 is welded and fixed to the bottom surface of the upper distribution box 1. The back plate of the reinforcing rib 123 is located on one side near the upper discharge port 122. The top of the back plate of the reinforcing rib 123 contacts the upper screen 121 and can be used to support the upper screen 121. The lower end of the upper screen 121 abuts against the upper part of the inner wall of the partition plate 11. In other embodiments other than this embodiment, the lower end of the upper screen 121 is welded and fixed to the partition plate 11. The bottom of the screening area 12, near the upper discharge port 122, forms an upward-facing shape on both sides. Figure 3The rolled edge 124 shown is close to the inner wall of the upper material distribution box 1, and a reinforcing nail 125 is also provided at this location to fix the rolled edge 124 to the inner wall of the upper material distribution box 1. In other embodiments besides this one, weld points can be added to the rolled edge 124 and the inner wall of the upper material distribution box 1 for further welding and fixing. In order to drain the oil in the area between the reinforcing rib 123 and the partition plate 11, an oil outlet 126 is provided at the lowest point of this area. The lowest point of the storage area 13 is a constricted structure with an opening in the middle of the constricted structure. The edges of the opening are rolled to form insertion slots 128, and a valve plate 129 is inserted into the opening. The two sides of the valve plate 129 are inserted into the insertion slots 128; a handle is also welded to the top of the valve plate 129.

[0024] The lower distribution box 2 is equipped with a lower screen 21, which includes multiple inclined rods arranged along the inclined direction of the lower distribution box 2. Adjacent inclined rods have gaps between them and are arranged in parallel rows. A fixing rod is installed below the row of inclined rods, and the inclined rods are welded to the fixing rod. The lower screen 21 is welded to the inner wall of the lower distribution box 2, and there is a distance between the lower screen 21 and the bottom surface of the lower distribution box 2. An oil baffle 22 is welded to the lower end of the lower distribution box 2 to prevent oil from flowing out of the lower area of ​​the lower screen 21. An oil outlet 126 is also provided on the bottom surface of the lower distribution box 2 near the lower end, and an oil guide pipe 127 is connected to the oil outlet 126.

[0026] The operating method of the sleeve discharge screening machine is as follows:

[0027] The steering sleeve and waste material are discharged from the machine outlet and conveyed by the conveyor belt 4 into the upper distribution box 1. As the waste material rolls down the upper part of the upper distribution box 1, because the waste particles are smaller than the diameter of the steering sleeve, the waste material falls below the upper screen 121 and into the lower screen 21 through the upper discharge port 122. The lower screen 21 is composed of multiple inclined rods arranged along the length of the lower distribution box 2. Therefore, the waste material falling into the lower screen 21 can smoothly slide down the inclined rods into the waste box 5. The steering sleeve on the upper screen 121 falls into the storage area 13. When a certain amount of material has accumulated, the handle is pulled to open the valve plate 129, and the steering sleeve enters the product collection box 6. Of course, the valve plate 129 can also be kept open, and the steering sleeve can fall directly into the product collection box 6. The purpose of setting up the storage area 13 is to realize the temporary storage of products, especially when it is necessary to change the product collection box 6, the screening can be carried out without interruption. Since the produced products contain oil, the oil can be collected during the screening process. Specifically, the oil in the upper distribution box 1 and the lower distribution box 2 flows through the oil outlet 126 and the oil guide pipe 127 into the oil drum 1271 for collection, which greatly reduces the original screening burden.
