Description

Technical Field

[0001] This utility model belongs to the field of screening technology, and in particular relates to a vibration screening device. Background Technology

[0002] When fasteners such as screws and bolts are polished using a polishing machine, particulate impurities are often trapped inside after polishing. Therefore, these impurities generally need to be screened out. Screening fasteners typically involves using a vibrating screen. However, currently, vibrating screens generally lack flow-limiting baffles. Consequently, fasteners exiting the polishing machine tend to concentrate and fall rapidly from one end of the screen, resulting in incomplete impurity removal. Utility Model Content

[0003] In view of the shortcomings and defects in the existing technology, the purpose of this utility model is to provide a vibration screening device, which solves the problem that the existing vibration screening device does not have a flow limiting baffle, so the fasteners coming out of the polishing machine tend to concentrate and fall quickly from one end of the vibration screening device, resulting in insufficient removal of impurities from the fasteners.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a vibrating screening device, comprising a U-shaped screen frame, a vibrating motor on one side of the screen frame, a screen mesh at the bottom of the screen frame, a first receiving box below the screen frame, a discharge port at one end of the U-shaped opening of the screen frame, a second receiving box at one end of the discharge port of the screen frame, a fixed rod in the middle of the screen frame, an adjustable flow-limiting baffle on the fixed rod, the baffle being inserted into the screen frame below, the screen mesh comprising a rectangular frame, multiple support rods fixed on the rectangular frame, multiple screening rods fixed on the support rods inside the rectangular frame, gaps between adjacent screening rods, a support plate at the bottom of the screen frame where the screen mesh is placed, the screen mesh being detachably placed on the support plate, a clamping member on the screen frame capable of pressing the screen mesh, a downwardly inclined transition plate on the screen frame at the discharge port, and the second receiving box placed below the transition plate.

[0005] As a further improvement of this utility model, the clamping component includes two clamping rods, which are respectively pressed on both sides of the screen. Multiple rotating blocks are fixed above each clamping rod. A fixing plate is fixed above each rotating block on the screen frame. The fixing plate is provided with threaded holes, and an adjusting bolt is threadedly connected to the fixing plate. The bottom end of the adjusting bolt is rotatably connected to the rotating block.

[0006] As a further improvement of this utility model, a torsion ring is provided above the adjusting bolt.

[0007] As a further improvement of this utility model, the flow-limiting baffle is provided with an elongated hole, and the fixing rod is provided with an opening at a position corresponding to the elongated hole. The flow-limiting baffle and the fixing rod are connected by fastening bolts passing through the elongated hole and the opening.

[0008] As a further improvement of this utility model, side baffles are provided on both sides of the transition plate.

[0009] Compared with the prior art, this utility model has the following advantages:

[0010] 1. By setting a screen frame, a screen mesh is installed inside the screen frame, and the screen mesh is pressed into the screen frame by a clamping component. Therefore, when cleaning the screen mesh or cleaning impurities in the first receiving box below the screen frame, the clamping component can be opened to remove the screen mesh, which is convenient for cleaning and replacing the screen mesh or removing impurities from the first receiving box.

[0011] 2. By incorporating an adjustable flow-limiting baffle within the sieve frame, the fasteners exiting the polishing machine are blocked and their flow restricted as they move towards the discharge port. This prevents the fasteners from flowing too quickly into the second receiving box, thus ensuring thorough removal of impurities or small, defective fasteners and improving the screening effect. Furthermore, the adjustable height of the flow-limiting baffle allows operators to adjust the flow restriction level, making it more flexible in operation.

[0012] 3. By providing a downwardly inclined transition plate at the discharge port on the screen frame, the fasteners can be transitioned as they flow out.

[0013] 4. By configuring the clamping components as a clamping rod, rotating block, fixed plate, and adjusting bolt, the height of the clamping rod can be adjusted by turning the adjusting bolt, thereby clamping or releasing the screen and allowing it to be pulled out and removed. A torsion ring is provided above the adjusting bolt for easy turning.

[0014] 4. By setting elongated holes on the flow-limiting baffle and openings on the fixing rod, the height of the flow-limiting baffle can be adjusted. Then, the flow-limiting baffle is fixed to the fixing rod with fastening bolts, making the adjustment operation simple. Attached Figure Description

[0021] The following is in conjunction with the appendix Figure 1-4 The present invention will be described in further detail below. For clarity, only the structures relevant to the inventive features of the present invention are shown in the figures.

[0022] For ease of description, the coordinate system is defined as follows: Figure 1 As shown, the left and right directions are horizontal, the front and back directions are vertical, and the up and down directions are vertical.

[0023] This utility model discloses a vibration screening device. (Refer to...) Figure 1 and Figure 4 A vibrating screening device includes a U-shaped screen frame 1, with one end of the U-shaped opening of the screen frame 1 serving as a discharge port 4. A second receiving box 10 is provided at one end of the discharge port 4. A vibrating motor (not shown in the attached diagram) is located on one side of the screen frame 1. A screen mesh 2 is located at the bottom of the screen frame 1, gradually tilting downwards from the side furthest from the discharge port 4 to the side closest to the discharge port 4. A first receiving box 3 is fixedly connected to the lower part of the screen frame 1. A fixing rod 5 is located in the middle of the screen frame 1, and an adjustable flow-limiting baffle 6 is provided on the fixing rod 5. This allows operators to adjust the height of the flow-limiting baffle 6 to change the flow restriction, making it more flexible to use. The flow-limiting baffle 6 is inserted into the screen frame 1. Specifically, as shown... Figure 1 and Figure 3 As shown, the flow-limiting baffle 6 has an elongated hole 11, and the fixing rod 5 has an opening at a position corresponding to the elongated hole 11. The flow-limiting baffle 6 and the fixing rod 5 are connected by fastening bolts 12 passing through the elongated hole 11 and the opening. Therefore, the height of the flow-limiting baffle 6 can be adjusted, and then the flow-limiting baffle 6 can be fixed to the fixing rod 5 with the fastening bolts 12, making the adjustment operation simple.

[0024] The screen 2 includes a rectangular frame 201, on which multiple support rods 202 are welded and fixed. Multiple screening rods 203 are welded and fixed inside the rectangular frame 201 on the support rods 202. A gap is left between adjacent screening rods 203. A support plate 7 is provided at the bottom of the screen frame 1 at the position where the screen 2 is set. The screen 2 is detachably placed on the support plate 7. A clamping member 8 that can press the screen 2 is provided on the screen frame 1.

[0025] In addition, a downwardly inclined transition plate 9 is fixed on the screen frame 1 at the discharge port 4. Side baffles 13 are provided on both sides of the transition plate 9. The second receiving box 10 is placed below the transition plate 9, so that the fasteners can be transitioned when they flow out.

[0026] For clamping element 8, such as Figure 2 and Figure 4 As shown, the clamping component 8 includes two clamping rods 801, which press against both sides of the screen 2. Multiple rotating blocks 802 are fixed above each clamping rod 801. A fixing plate 803 is fixed above each rotating block 802 on the screen frame 1. The fixing plate 803 has threaded holes, and an adjusting bolt 804 is threaded onto it. The bottom end of the adjusting bolt 804 is rotatably connected to the rotating block 802. A torsion ring 805 is provided above the adjusting bolt 804 for easy tightening. By configuring the clamping component 8 with clamping rods 801, rotating blocks 802, fixing plate 803, and adjusting bolts 804, the height of the clamping rods 801 can be adjusted by tightening the adjusting bolts 804, thereby clamping or releasing the screen 2 and allowing it to be pulled out.

[0027] The technical principle of this invention is as follows: Fasteners exiting the polishing machine fall onto the screen 2 and, under the vibration of the screen 2, flow towards the discharge port 4 of the screen frame 1, eventually falling into the second receiving box 10. During the vibration and flow of the fasteners, impurities and small fasteners that do not conform to the specifications will fall directly from the screen 2 into the first receiving box 3 below the screen 2, thus completing the screening of fasteners and impurities. The flow-limiting baffle 6 in this device restricts the flow of fasteners.

[0028] The technical advantages of this invention are as follows: By setting a screen frame 1, with a screen mesh 2 inside the screen frame 1, and pressing the screen mesh 2 into the screen frame 1 with a clamping member 8, the clamping member 8 can be opened to remove the screen mesh 2 when cleaning the screen mesh 2 or cleaning impurities in the first receiving box 3 below the screen frame 1, making it convenient to clean and replace the screen mesh 2 or remove impurities from the first receiving box 3. Furthermore, an adjustable flow-limiting baffle 6 is provided inside the screen frame 1. Therefore, the fasteners coming out of the polishing machine are blocked and limited in flow as they move towards the discharge port 4, preventing the fasteners from flowing too quickly into the second receiving box 10. This would prevent incomplete removal of particulate impurities or unqualified small fasteners mixed in with the fasteners, thus affecting the screening effect.
