[0008] By adopting the above scheme, the wire drawing machine needs to add wire drawing liquid during the wire drawing process. Direct discharge of the wire drawing liquid after use will have an impact on the environment. Therefore, a circulating filter device is arranged on the wire drawing machine, and the circulating filter device includes a water injection pipe, a water return pipe, a filter box and a filter element. The wire drawing machine is provided with a spray device and a liquid collecting tank.

The return pipe is arranged between the liquid collecting tank and the filter box, and the two ends of the return pipe are fixedly connected to the liquid collecting tank and the filter box respectively, so that the wire drawing liquid flowing into the wire drawing machine through the water injection pipe can flow into the filter box through the recovery pipe, so as to circulate; after flushing the cable, the wire drawing liquid flows into the filter box through the return pipe. To carry metal slag, in order to prevent the metal slag in the filter box from entering the wire drawing machine through the water injection pipe, a filter is arranged between the water inlet pipe and the water outlet pipe, and the filter is used to filter the wire drawing liquid flowing into the filter box through the return pipe; the metal slag filtered by the filter will accumulate on the filter, and in order to clean the metal chips accumulated on the filter, a chip suction device is also arranged, which includes a chip suction hood, a connecting piece and a chip storage box, the chip suction hood is located between the filter and the top wall of the filter box, the connecting piece is arranged between the chip suction hood and the chip storage box, and the two ends of the connecting piece are respectively threadedly connected to the chip suction hood and the chip storage box, and when the metal slag on the filter is cleaned, the chip suction hood absorbs the metal slag, and the adsorbed metal slag enters the chip storage box through the connecting piece.

[0009] Furthermore, the filter element comprises a filter frame and a filter net, wherein the filter net is embedded in the filter frame; wherein the filter frame comprises an upper frame and a lower frame, wherein the upper frame and the lower frame are plugged together, and a cavity is formed between the upper frame and the lower frame.

[0010] Furthermore, the upper frame and the lower frame are both provided with grooves, and after the upper frame and the lower frame are plugged in and matched, a cavity is formed between the upper frame and the lower frame, and a heating device is provided in the cavity, and the heating device is used to heat the filter screen.

[0011] By adopting the above scheme, the filter frame is divided into an upper frame and a lower frame, and the upper frame and the lower frame are both provided with grooves. The upper frame and the lower frame are plugged together to form a cavity, and the cavity can be used to place a heating device; the metal chips filtered by the filter element are in a moist state, and the metal chips in the moist state have a large weight and are not easily sucked up by the chip suction hood, so a heating device is placed in the cavity, and the heating device is used to heat the metal chips. The heated metal chips are in a dry state, which is convenient for being sucked up by the chip suction hood, and the upper frame and the lower frame are plugged together and can be disassembled, which is convenient for inspection and replacement of the heating device.

[0012] Furthermore, a sliding part is provided at the connection between the chip suction hood and the inner wall of the filter box, and the sliding part includes a lead screw, a sliding ring, a limit rod and a limit ring, the two ends of the lead screw are respectively fixedly connected to the side walls of the filter box, the sliding ring is sleeved on the lead screw, and the sliding ring is threadedly connected to the lead screw; the limit rod is arranged on the side away from the lead screw and parallel to the lead screw, the two ends of the limit rod are respectively fixedly connected to the side walls of the filter box, the limit ring is sleeved on the limit rod, and the limit rod is slidably connected to the limit ring; the chip suction hood is arranged between the sliding ring and the limit ring, and the two ends of the chip suction hood are respectively fixedly connected to the sliding ring and the limit ring.

[0013] By adopting the above scheme, the chip suction hood is fixedly arranged in the filter box, and the adsorption area is relatively small. Therefore, a sliding member is arranged between the chip suction hood and the inner wall of the filter box. The sliding member can make the chip suction hood slide in the filter box to increase the chip suction area of ​​the chip suction hood. The sliding member includes a lead screw and a sliding ring. The two ends of the lead screw are respectively fixedly connected to the side walls of the filter box. The sliding ring is sleeved on the lead screw. The sliding ring is threadedly connected to the lead screw. The chip suction hood is fixedly connected to the sliding ring. When the lead screw is pushed and the sliding ring is driven to move by the lead screw, since the sliding ring is not restricted, the sliding ring will rotate around the axis of the lead screw, thereby driving the chip suction hood fixedly connected to the sliding ring to rotate around the axis of the lead screw. Therefore, a limit rod and a limit block are arranged at one end of the chip suction hood away from the lead screw, and the two ends of the limit rod are respectively fixedly connected to the side walls of the filter box. The limit ring is sleeved on the limit rod, and the limit rod is slidably connected to the limit ring.

[0015] By adopting the above scheme, the connecting piece is used to connect the dust storage box and the chip suction hood. The metal chips absorbed by the chip suction hood can enter the dust storage box through the connecting piece. The chip suction hood will make reciprocating motion along the lead screw in the process of absorbing metal chips in the filter box, so the connecting piece needs to be designed as a retractable piece. Therefore, the connecting piece includes an inner tube, an outer tube and an annular gasket. The diameter of the outer tube is larger than the diameter of the inner tube. The two ends of the outer tube are respectively fixedly connected to the filter box and the chip storage box. The outer tube is sleeved outside the inner tube, and an annular gasket is arranged between the outer tube and the inner tube. The outer ring side wall of the annular gasket is slidably connected to the outer tube, and the inner ring of the annular gasket is fixedly connected to the inner tube, so that the inner tube can make reciprocating motion in the outer tube, thereby cooperating with the movement of the chip suction hood in the filter box.

[0016] Furthermore, the filter box side wall is provided with an inspection port, and a sealing plate is provided corresponding to the inspection port, the sealing plate is used to seal the inspection port, and one side of the sealing plate is rotatably connected to the side wall of the inspection port.

[0017] By adopting the above scheme, an inspection port is opened on the side wall of the filter box, and the chip suction hood and the heating block in the filter box can be inspected and maintained through the inspection port. Because the filter box needs to be in a sealed state when the filter box is in a circulating operation, a sealing plate is provided corresponding to the inspection port, and one side of the sealing plate is rotatably connected to the side wall of the inspection port, so that by pulling the sealing plate, the sealing plate can rotate along the connection with the inner wall of the inspection port, thereby controlling the opening or closing state of the inspection port.

[0018] Furthermore, a guide plate is provided at one end of the dust hood connected to the limiting ring and the other end connected to the sliding ring, each guide plate is fixedly connected to the dust hood, and one end of each guide plate away from the dust hood abuts against the filter element.

[0019] By adopting the above scheme, there are gaps between the end of the chip hood connected to the limit ring and the end connected to the sliding ring and the inner wall of the filter box. When the chip hood is used to absorb metal chips in the filter box, the metal chips in the gap between the chip hood and the inner wall of the filter box cannot be absorbed. Therefore, a guide plate is provided in the dust collector, and the guide plate is used to absorb the metal chips remaining in the gap between the chip hood and the inner wall of the filter box.

[0020] Furthermore, a locking member is provided on a side of the sealing plate away from the rotational connection with the side wall of the inspection port, and the locking member is used to limit the position of the sealing plate when the sealing plate seals the inspection port.

[0021] By adopting the above solution, the driving member is fixedly connected to the lead screw, and when the sealing plate is used to seal the inspection port, the locking member can limit the position of the sealing plate so that the sealing plate is fixedly connected to the inspection port.

The wire drawing liquid will carry metal slag. In order to prevent the metal slag in the filter box from entering the wire drawing machine through the water injection pipe, a filter is arranged between the water inlet pipe and the water outlet pipe. The filter is used to filter the wire drawing liquid that flows into the filter box through the return pipe. The metal slag filtered by the filter will accumulate on the filter. In order to clean the metal chips accumulated on the filter, a chip suction device is also arranged. The chip suction device includes a chip suction cover, a connecting piece and a chip storage box. The chip suction cover is located between the filter and the top wall of the filter box. The connecting piece is arranged between the chip suction cover and the chip storage box.

[0024] 2. A connecting piece is provided, and the connecting piece is used to connect the dust storage box and the chip suction hood. The metal chips absorbed by the chip suction hood can enter the dust storage box through the connecting piece. The chip suction hood will make reciprocating motion along the lead screw in the process of absorbing metal chips in the filter box.

The inner ring of the annular pad is fixedly connected to the inner tube, so that the inner tube can make reciprocating motion in the outer tube, thereby cooperating with the movement of the chip suction hood in the filter box.

[0025] 3. By setting a sliding part, the chip suction cover is fixedly set in the filter box. The adsorption area is relatively small. Therefore, a sliding part is set between the chip suction cover and the inner wall of the filter box. The sliding part can make the chip suction cover slide in the filter box to increase the chip suction area of ​​the chip suction cover. The sliding part includes a lead screw and a sliding ring. The two ends of the lead screw are respectively fixedly connected to the side walls of the filter box. The sliding ring is sleeved on the lead screw. The sliding ring is threadedly connected to the lead screw. The chip suction cover is fixedly connected to the sliding ring. When the lead screw is pushed, the sliding ring is driven by the lead screw to move. Since there is no restriction on the sliding ring, the sliding ring will rotate around the axis of the screw, and then drive the chip suction hood fixedly connected to the sliding ring to rotate around the axis of the screw. Therefore, a limit rod and a limit block are provided at the end of the chip suction hood away from the screw, and the two ends of the limit rod are respectively fixedly connected to the side walls of the filter box, and the limit ring is sleeved on the limit rod. The limit rod is slidably connected to the limit ring, and the end of the chip suction hood away from the sliding ring is fixedly connected to the limit ring.
