Description

Technical Field

[0001] This utility model relates to the field of wire drawing technology, specifically to a dustproof structure for the inlet of wire drawing powder. Background Technology

[0002] In the wire drawing process, drawing powder is required to form a continuous lubricating film between the metal wire and the die, reducing interfacial friction and ensuring stable drawing. The conventional method involves placing a powder box containing the drawing powder in front of the drawing die. A lead-in hole is opened on the outer wall of the powder box on the side away from the die. The wire to be drawn, after being guided and positioned by a front guide wheel, passes through the lead-in hole into the powder box. As it passes through the powder box, the wire surface naturally picks up the drawing powder, and finally enters the drawing die to complete the drawing process smoothly.

[0003] However, since the powder box on the wire drawing machine is not specifically designed for wires of a single diameter, the opening diameter of the lead hole is generally designed to be compatible with the largest diameter wire, with an appropriate gap reserved. Furthermore, the hole diameter may further enlarge during the friction process of the wire passing through for an extended period. When the wire passes through the lead hole, a relatively large gap (usually 2-5mm) is left. Under the influence of equipment vibration and wire movement, the drawing powder in the powder box will leak out from the gap between the lead hole and the wire, and disperse and fly away under vibration, forming dust.

[0004] Due to environmental protection requirements in production, dust control is necessary. Currently, processing sites typically use vacuum cleaners installed on the outside of the powder box to directly absorb leaked dust. However, this method not only increases equipment configuration costs but also results in redundant equipment layout. Therefore, a dustproof structure for the inlet of wire drawing powder is proposed to solve the aforementioned problems. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model proposes a dustproof structure for the inlet of wire drawing powder, which solves the technical problem mentioned in the background that most existing dustproof structures for wire drawing powder absorb leaked dust by adding a vacuum cleaner, which not only increases processing costs but also makes the equipment layout redundant.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a dustproof structure for the inlet of wire drawing powder, comprising:

[0007] The powder box has a drawing mold on one side; and

[0008] A silencing chamber is located on the side of the powder box away from the drawing die and is connected to the powder box. The silencing chamber has an upper air hole that communicates with the outside. The wire passes through the silencing chamber, extends into the powder box, and exits from the drawing die.

[0009] In a preferred embodiment, the silencing cavity includes:

[0010] The mounting tube has one end connected to the powder box, and the upper air hole is opened on the tube wall of the mounting tube.

[0011] A first sealing component is disposed at the connection between the mounting tube and the powder box to seal one end of the mounting tube; and

[0012] The second sealing component is disposed at the end of the mounting tube away from the toner cartridge to close the other end of the mounting tube. The wire passes through the first sealing component, passes through the mounting tube, and then extends into the toner cartridge through the second sealing component.

[0013] In a preferred embodiment, the first sealing component includes a first sealing block disposed inside the installation tube, and the first sealing block has a wire outlet hole.

[0014] In a preferred embodiment, the second sealing assembly includes a second sealing block disposed inside the mounting tube and spaced apart from the first sealing block, the second sealing block having an inlet hole and the upper air hole being located between the second sealing block and the first sealing block.

[0015] In a preferred embodiment, both the first sealing block and the second sealing block are detachably disposed within the mounting tube.

[0016] In a preferred embodiment, the bottom of the settling chamber is provided with an exhaust port, which is connected to a receiving bag via a discharge pipe.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] By introducing the wire from the settling chamber into the toner cartridge and then drawing it out through a drawing die, the wire is coated with toner as it passes through the inside of the cartridge. During coating, the drawing powder leaks from the cartridge into the settling chamber. As the wire moves, the upper vent creates a suction force towards the inside, causing the airflow to circulate or turbulent within the settling chamber. This prevents gas from escaping through the upper vent, effectively preventing dust from escaping from the end of the settling chamber furthest from the toner cartridge and from the upper vent, thus reducing pollution to the production environment and minimizing raw material waste.

[0025] The present invention will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present invention and should not be construed as limiting the scope of protection of the present invention. Those skilled in the art can make some non-essential improvements and adjustments to the present invention based on the above application content.

[0026] Example:

[0027] like Figures 1 to 3 As shown, this utility model provides a dustproof structure for the inlet of wire drawing powder, including a powder box 1, a wire drawing mold 2 on one side of the powder box 1, and a settling chamber connected to the powder box 1 on the side of the powder box 1 away from the wire drawing mold 2. An upper air hole 9 communicating with the outside is opened on the settling chamber. A wire 3 passes through the settling chamber, extends into the powder box 1, and exits from the wire drawing mold 2. The end of the wire 3 is connected to a wire drawing mechanism, allowing the wire 3 to move within the powder box 1 for powder application. When the wire 3 passes through the settling chamber, a negative pressure is created inside the settling chamber, and gas enters the settling chamber through the upper air hole 9, forming a circulating or turbulent flow. The gas flow direction is towards the powder box 1, effectively preventing dust from leaking out of the settling chamber and achieving a dustproof effect. Compared to the traditional method of directly adding a vacuum cleaner 12 to the wire inlet end of the powder box 1, this dustproof structure can reduce production costs and equipment requirements.

[0028] like Figure 3As shown, in this embodiment, the silencing chamber includes an installation tube 4. One end of the installation tube 4 is connected to the toner cartridge 1. An upper vent 9 is formed on the wall of the installation tube 4. A first sealing component is provided at the connection between the installation tube 4 and the toner cartridge 1, which closes one end of the installation tube 4. A second sealing component is provided at the end of the installation tube 4 away from the toner cartridge 1, which closes the other end of the installation tube 4. The wire 3 passes through the first sealing component, through the installation tube 4, and extends into the toner cartridge 1 through the second sealing component. The first sealing component includes a first sealing block 5 disposed inside the installation tube 4, and the first sealing block 5 has a wire outlet hole 6. The second sealing component includes a second sealing block 7 disposed inside the installation tube 4 and spaced apart from the first sealing block 5, and the second sealing block 7 has a wire inlet hole 8. The upper vent 9 is formed between the second sealing block 7 and the first sealing block 5.

[0029] The first sealing block 5 and the second sealing block 7 work together with the mounting tube 4 to form a quiet chamber. The wire 3 can enter the quiet chamber through the inlet hole 8 and extend into the powder box 1 through the outlet hole 6. The diameters of the inlet hole 8 and the outlet hole 6 are both smaller than the diameter of the mounting tube 4, so that the wire 3 can drive the gas flow when passing through the mounting tube 4, so that a negative pressure is formed in the mounting tube 4, and the gas is drawn into the mounting tube 4 from the upper air hole 9, preventing the gas from flowing out from the upper air hole 9 and the inlet hole 8.

[0030] like Figure 3 As shown, in this embodiment, the first sealing block 5 and the second sealing block 7 are both detachably installed in the mounting pipe 4. The first sealing block 5 and the second sealing block 7 can be installed by screw connection or interference fit, so as to facilitate their replacement after wear and avoid the gas entering from the upper air hole 9 from being unable to form circulation or turbulence due to the hole being too large.

[0031] like Figure 3 As shown, in this embodiment, an exhaust port 10 is also provided at the bottom of the settling chamber, and the exhaust port 10 is connected to a receiving bag through a discharge pipe 11. The dust that leaks into the settling chamber from the outlet port 6 settles and is discharged from the exhaust port 10 into the receiving belt, realizing the reuse of the drawing powder and reducing material waste.

[0032] The specific usage and beneficial effects of this utility model are as follows:

[0033] By introducing wire 3 from the settling chamber into the powder box 1 and then drawing wire 3 out of the powder box 1 through the drawing die 2, powder is applied as wire 3 passes through the inside of the powder box 1. During the powder application process, the drawing powder leaks from the powder box 1 into the settling chamber. As wire 3 moves, it causes the upper air hole 9 to form a suction force towards the inside. The airflow forms a circulation or turbulence in the settling chamber, and the gas will not be discharged from the upper air hole 9. This effectively prevents dust from being discharged from the end of the settling chamber away from the powder box 1 and from the upper air hole 9, reducing pollution to the production environment and minimizing waste of raw materials.

[0034] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It will be apparent to those skilled in the art that this utility model is not limited to the details of the exemplary embodiments described above. Modifications or improvements can be made to this utility model, which is obvious to those skilled in the art. Therefore, all such modifications or improvements made without departing from the spirit of this utility model fall within the scope of protection claimed by this utility model.
