Description

Technical Field

[0001] This utility model relates to the field of wire drawing machines, and in particular to a novel wire drawing machine for cable manufacturing. Background Technology

[0002] Wire drawing machines are widely used mechanical equipment in industrial applications. Also known as wire drawing machines, they are widely used in industries such as machinery manufacturing, hardware processing, petrochemicals, plastics, bamboo and wood products, and wire and cable manufacturing. In cable production, the raw metal material needs to be drawn into smaller wires to meet production requirements. In the actual wire drawing process, the diameter of the cable strands is gradually reduced through multiple drawing operations.

[0003] Chinese patent application number 202022466927.8 discloses a cable drawing machine, including a support frame. A wire guiding mechanism is located on one side of the support frame, and a drive mechanism is located on the other side. Multiple wire drawing mechanisms are located between the drive mechanism and the wire guiding mechanism. Wire guiding mechanisms are located on both sides of the multiple wire drawing mechanisms. The wire guiding mechanisms on both sides are connected to a second motor via belts. A metal wire sequentially passes through the wire guiding mechanism, the wire guiding mechanism, the wire drawing mechanism, and the drive mechanism. During the wire drawing process, the metal wire is stretched and deformed by the wire drawing die. Friction occurs between the surface of the metal wire and the wire drawing die, causing metal debris to fall off the surface of the metal wire, forming dust. However, this wire drawing machine does not have a dust removal function. If the dust generated during the wire drawing process is inhaled by the operator, it may damage the respiratory tract. Long-term exposure to an environment containing metal dust may lead to respiratory diseases such as pneumoconiosis. Furthermore, some metal dust (such as heavy metal dust such as lead and cadmium dust) may also harm other organs of the human body. Utility Model Content

[0004] The purpose of this invention is to provide a new type of wire drawing machine for cable manufacturing, which solves the problem that the above-mentioned wire drawing machines do not have a dust removal function and that dust overflow affects the health of workers.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] This utility model discloses a novel wire drawing machine for cable manufacturing, comprising a support frame, a wire guiding mechanism and a driving mechanism on the top surface of the support frame, a plurality of wire drawing mechanisms between the wire guiding mechanism and the driving mechanism, and wire guiding mechanisms on both sides of the plurality of wire drawing mechanisms. The wire guiding mechanisms on both sides are connected to a first motor via belts. Metal wires sequentially pass through the wire guiding mechanism, the wire guiding mechanism, the wire drawing mechanism and the driving mechanism. A protective cover is provided above the support frame, and a liftable dust collection cover is provided inside the protective cover and above the plurality of wire drawing mechanisms. A suction fan is provided on the rear side of the protective cover, and a dust treatment box is provided on the support frame and on the rear side of the protective cover. The air inlet of the suction fan is connected to the dust collection cover via a pipe, and the air outlet of the suction fan is connected to the dust treatment box via a pipe.

[0007] Furthermore, a lifting mechanism is provided at the top of the protective cover, and the dust suction cover is located on the bottom surface of the lifting mechanism.

[0008] Furthermore, the lifting mechanism includes a second motor mounted on the top of the protective cover. The output end of the second motor is provided with a bidirectional lead screw. A movable seat is threaded onto the forward and reverse threaded sections of the bidirectional lead screw. The movable seat is connected to the mounting plate via a connecting rod. A telescopic support rod is provided between the mounting plate and the protective cover.

[0009] Furthermore, the number of telescopic support rods is set to four, and the four telescopic support rods are located at the four corners of the top surface of the mounting plate.

[0010] Furthermore, the telescopic support rod includes a fixed tube, the top end of which is connected to the protective cover, and a movable tube is provided at the bottom of the fixed tube, the bottom end of which is connected to the top surface of the mounting plate.

[0011] Furthermore, the dust treatment box has an air inlet at the top, a treatment chamber and a transition chamber inside, a filter element inside the treatment chamber, a dust collection hopper below the treatment chamber, a central channel of the filter element communicating with the transition chamber, and an air outlet at the bottom of the transition chamber.

[0024] like Figure 1-7As shown, a novel wire drawing machine for cable manufacturing includes a support frame 1. A wire guiding mechanism 2 and a drive mechanism 5 are arranged on the top surface of the support frame 1. A plurality of wire drawing mechanisms 4 are arranged between the wire guiding mechanism 2 and the drive mechanism 5. Wire straightening mechanisms 3 are arranged on both sides of the plurality of wire drawing mechanisms 4. The wire straightening mechanisms 3 on both sides are connected to a first motor 7 via a belt 6. A metal wire 8 sequentially passes through the wire guiding mechanism 2, the wire straightening mechanism 3, the wire drawing mechanism 4, and the drive mechanism 5. The wire guiding mechanism 2, the wire straightening mechanism 3, the wire drawing mechanism 4, the drive mechanism 5, the belt 6, and the first motor 7 are all existing technologies, and their specific structures are not described in detail here. A protective cover 9 is installed above the support frame 1. An adjustable dust collection hood 16 is provided inside and above several of the wire drawing mechanisms 4. A suction fan 17 is mounted on the rear side of the protective cover 9 via a bracket. A dust treatment box 18 is mounted on the support frame 1 and located on the rear side of the protective cover 9. The air inlet of the suction fan 17 is connected to the dust collection hood 16 via a pipe, the length of which can be changed. The air outlet of the suction fan 17 is connected to the dust treatment box 18 via a pipe. The main body of the dust collection hood 16 is a rectangular square tube, and a flared mouth is connected to the bottom of the rectangular square tube. A box door is hinged to the front of the protective cover 9, and an observation window is installed on the box door. The left and right sides of the protective cover 9 are respectively provided with an inlet and an outlet for the metal wire 8 to pass through.

[0025] like Figure 2 As shown, a lifting mechanism is installed on the top of the protective cover 9, and the dust suction cover 16 is installed on the bottom surface of the lifting mechanism. The lifting mechanism includes a second motor 10 installed on the top of the protective cover 9. The output end of the second motor 10 is connected to a bidirectional lead screw 11. The bidirectional lead screw 11 is rotatably connected to the protective cover 9 through bearings and supports. A movable seat 12 is threaded onto the positive and negative thread sections of the bidirectional lead screw 11. The movable seat 12 is connected to the mounting plate 15 through a connecting rod 13. The upper and lower ends of the connecting rod 13 are respectively hinged to the movable seat 12 and the mounting plate 15. A telescopic support rod 14 is installed between the mounting plate 15 and the protective cover 9. The number of telescopic support rods 14 is set to four, and the four telescopic support rods 14 are installed at the four corners of the top surface of the mounting plate 15.

[0026] like Figure 5 As shown, the telescopic support rod 14 includes a fixed tube 14-1, the top end of which is connected to the protective cover 9. A movable tube 14-2 is provided at the lower part of the fixed tube 14-1. The bottom end of the movable tube 14-2 is connected to the top surface of the mounting plate 15. The top end of the movable tube 14-2 is inserted into the fixed tube 14-1. A limiting boss is connected to the top end of the movable tube 14-2. The size of the limiting boss is larger than the size of the through hole at the bottom end of the fixed tube 14-1.

[0027] In use, the second motor 10 is started, which drives the bidirectional lead screw 11 to rotate. The rotation of the bidirectional lead screw 11 causes the two moving seats 12 to move closer or further apart. When the two moving seats 12 move closer together, they cause the mounting plate 15 to rise. When the two moving seats 12 move further apart, they cause the mounting plate 15 to fall, thereby causing the dust hood 16 to fall and move closer to the wire drawing mechanism 4 to suck away the dust generated during the wire drawing process.

[0028] like Figure 6-7 As shown, the top of the dust handling box 18 is connected to an air inlet 18-1, which is connected to the air outlet of the suction fan 17 via a pipe. The interior of the dust handling box 18 is divided into a processing chamber 18-3 and a transition chamber 18-4 by a partition. Two filter elements 19 are installed in the processing chamber 18-3. A dust collection hopper 20 is connected to the bottom of the processing chamber 18-3 for collecting dust. Through holes are provided on the partition. The central channel of the filter element 19 is connected to the transition chamber 18-4 through the through holes. An air outlet 18-2 is connected to the bottom surface of the transition chamber 18-4. A sealed door is installed on the left side of the dust handling box 18. The filter element 19 can be replaced by opening the sealed door.

[0029] The working process of this utility model is as follows:

[0030] First, the metal wire 8 is inserted into the feed port on the left side of the protective cover 9. The metal wire 8 passes through the wire guiding mechanism 2, the wire guiding mechanism 3, the wire drawing mechanism 4, and the drive mechanism 5 in sequence, and exits from the discharge port on the right side of the protective cover 9. The box door in front of the protective cover 9 is closed, and the wire drawing operation begins. Then, the second motor 10 is started. The second motor 10 drives the bidirectional lead screw 11 to rotate. The rotation of the bidirectional lead screw 11 causes the two moving seats 12 to move away from each other, causing the mounting plate 15 to descend, thereby causing the dust collection hood 16 to descend and move the dust collection hood 16 closer to the wire drawing mechanism 4. After that, the suction fan 17 is started. The suction fan 17 sucks the dust generated by the wire drawing operation into the dust treatment box 18. After the gas is filtered by the filter element 19, it is discharged through the air outlet 18-2.

[0031] The embodiments described above are merely preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model. Various modifications and improvements made to the technical solutions of the present utility model by those skilled in the art without departing from the spirit of the present utility model should fall within the protection scope defined by the claims of the present utility model.
