Description

Technical Field

[0001] The invention relates to the technical field of dust removal devices, in particular to a dust removal device for a wire drawing machine. Background Art

[0002] Wire drawing machines, as mechanical equipment widely used in the industrial field, have the main function of continuously stretching materials to improve their physical properties and surface finish. This process is not only used in the production pretreatment of metal products, such as steel wire, rope wire, prestressed steel wire, etc., but also involves many fields such as plastics, bamboo and wood products. However, in the wire drawing process, especially in metal wire drawing, a large amount of metal debris and dust will be generated. If these debris and dust are not handled, they will float into the air, causing serious air pollution problems, posing a threat to human health, and leading to a waste of resources.

[0003] The existing Chinese patent (CN212597972U) discloses a wire drawing machine dust removal device including a wire drawing machine support and fixed shell, a first protective baffle, a wire drawing rotating rod, an air intake connection hole, a dust filter, and an electric fan. A wind control switch is provided on one side of the wire drawing machine support and fixed shell, and a fan fixing base is connected to the wire drawing machine support and fixed shell on the side of the isolation protective plate. A rotating connection block is provided on the side of the wire drawing machine support and fixed shell located on the first protective baffle, and the wire drawing rotating rod is provided on the side of the rotating connection block away from the wire drawing machine support and fixed shell.

[0009] As a further illustration of the present invention, the inner wall at the bottom of the dust removal housing is an inclined surface, and the bottom end of the inclined surface is close to the top end of the ventilation housing.

[0010] As a further explanation of the present invention, a first rotating sleeve is provided on the outer wall of one end of the wire drawing die head, and blades are also provided on the outer wall of the first rotating sleeve. A blowing head is also provided on the outer side of the blades of the first rotating sleeve at one end of the blowing pipe. A chip breaker is provided on the inner wall of the first rotating sleeve, and one end of the chip breaker is fixed to the inner wall of the first rotating sleeve, and the other end is close to the end of the wire drawing die head.

[0011] As a further explanation of the present invention, a T-shaped slot is provided on one side of the second rotating sleeve, a T-shaped slider is provided inside the T-shaped slot, an L-shaped bracket is provided at one end of the T-shaped slider, one side of the L-shaped bracket is fixedly connected to the T-shaped slider, and the other side is located outside the center line of the wire drawing die head, and a cleaning brush is provided at the bottom of one side of the L-shaped bracket.

[0012] As a further explanation of the present invention, a V-shaped elastic sheet is provided on one side of the L-shaped bracket above the cleaning brush, a connecting column is provided on one side of the top of the V-shaped elastic sheet, and the top of the connecting column is fixedly connected to the inner wall of the second rotating sleeve.

[0013] As a further explanation of the present invention, there are four T-slots, and the four T-slots are evenly arranged in the circumferential direction on the second rotating sleeve.

[0014] As a further description of the present invention, through holes are provided at both ends of the dust removal shell, and a through hole is provided in the middle of the partition plate, and the through holes are used for the passage of wire drawing.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] The present invention realizes that when the dust removal device for the wire drawing machine is used, one end of the wire drawing passes through the dust removal shell, the wire drawing die head and the partition plate and is fixed to the winding roller, and the winding roller is driven to rotate by the winding motor to provide the driving force required for wire drawing. During the wire drawing process, when the wire drawing passes through the wire drawing die head, the inner diameter of the wire drawing die head end is slightly smaller than the diameter of the wire drawing, so that the diameter of the wire drawing is reduced after passing through the wire drawing die head. During the process of reducing the wire drawing diameter, debris will appear and some of the debris will directly fall on the bottom of the dust removal shell. Part of the debris will accumulate at the port of the wire drawing die head. For this part of the debris, the negative pressure fan blows air, and the blowing head blows air toward the blades outside the first rotating sleeve through the guidance of the blowing pipe, thereby driving the blades and the first rotating sleeve to rotate, thereby driving the chip breaker to rotate, and the debris accumulated at the end of the wire drawing die head is cut off by the chip breaker and falls to the bottom of the dust removal shell. The negative pressure suction of the negative pressure fan makes the debris at the bottom of the dust removal shell enter the ventilation shell, and finally enter the filter plate inside the negative pressure shell for storage of the debris;

[0018] Some of the debris will continue to move toward the winding roller as the wire drawing moves. When this part of the debris passes through the cleaning brush, the blowing head on the outside of the second rotating sleeve blows air to the blades, causing the blades and the second rotating sleeve to rotate, thereby driving the cleaning brush on the second rotating sleeve to rotate, and the debris on the outside of the wire drawing is brushed off by the cleaning brush to ensure that the debris on the wire drawing is cleaned and thoroughly cleaned. The cleaned debris also enters the top of the filter plate through the ventilation shell. The entire dust removal device can use excess wind force to rotate and clean the wire drawing surface while removing dust through negative pressure, ensuring that the outer wall of the wire drawing is clean, thereby improving the dust removal effect during the wire drawing process and utilizing the wind force of negative pressure suction to save energy.

The cleaning brush 24 is used to brush away the debris on the outside of the wire drawing to ensure that the debris on the wire drawing is cleaned and thoroughly cleaned. The cleaned debris also enters the top of the filter plate 11 through the ventilation shell 7. The entire dust removal device can use excess wind force to rotate and clean the wire drawing surface while removing dust through negative pressure, ensuring that the outer wall of the wire drawing is cleaned, improving the dust removal effect during the wire drawing process, and utilizing the wind force of negative pressure suction to save energy consumption.

[0032] A winding motor 3 is provided at the bottom of the housing 1, and a winding roller 2 is provided at one end of the output shaft of the winding motor 3.

The cleaning brush 24 is used to brush away the debris on the outside of the wire drawing to ensure that the debris on the wire drawing is cleaned and thoroughly cleaned. The cleaned debris also enters the top of the filter plate 11 through the ventilation shell 7. The entire dust removal device can use excess wind force to rotate and clean the wire drawing surface while removing dust through negative pressure, ensuring that the outer wall of the wire drawing is cleaned, improving the dust removal effect during the wire drawing process, and utilizing the wind force of negative pressure suction to save energy consumption.

[0041] A winding motor 3 is provided at the bottom of the housing 1, and a winding roller 2 is provided at one end of the output shaft of the winding motor 3. The winding roller 2 is used to wind up the wire after it passes through the wire drawing die 13. The function of the winding roller 2 is to receive and wind up the metal material or plastic material processed by the wire drawing die 13. During the wire drawing process, the material will be stretched when passing through the wire drawing die 13, thereby reducing its cross-sectional area and increasing its length, while improving the physical properties of the material such as strength and surface finish.

[0043] The inner wall at the bottom of the dust removal housing 5 is an inclined surface, and the bottom end of the inclined surface is close to the top of the ventilation housing 7. The design of the inclined surface makes it possible for the bottom of the dust removal housing 5 to no longer have a horizontal or concave dead angle, which helps the material to naturally slide down the inclined surface to the discharge port.

[0044] The outer wall of one end of the wire drawing die 13 is provided with a first rotating sleeve 14, and the outer wall of the first rotating sleeve 14 is also provided with blades 15.

The inner wall of the first rotating sleeve 14 is provided with a chip breaker 16, and one end of the chip breaker 16 is fixed to the inner wall of the first rotating sleeve 14, and the other end is close to the end of the wire drawing die 13. The negative pressure fan 10 blows air, and the blowing pipe 9 guides the blowing head 27 to blow air to the blades 15 outside the first rotating sleeve 14, thereby driving the blades 15 and the first rotating sleeve 14 to rotate, thereby driving the chip breaker 16 to rotate, and the chip breaker 16 cuts off the debris accumulated at the end of the wire drawing die 13 and drops it to the bottom of the dust removal housing 5.

[0045] A T-slot 21 is provided on one side of the second rotating sleeve 20, a T-slot 21 is provided inside a T-slot 22, an L-shaped bracket 23 is provided at one end of the T-slot 22, one side of the L-shaped bracket 23 is fixedly connected to the T-slot 22, and the other side is located outside the center line of the wire drawing die 13, and a cleaning brush 24 is provided at the bottom of one side of the L-shaped bracket 23. A V-shaped elastic sheet 25 is provided on one side of the L-shaped bracket 23 above the cleaning brush 24, and a connecting column 26 is provided on one side of the top of the V-shaped elastic sheet 25, and the top of the connecting column 26 is fixedly connected to the inner wall of the second rotating sleeve 20. The cleaning brush 24 is designed to slide by the T-slot 21 and the T-slot 22, and the elastic force of the V-shaped elastic sheet 25 allows the bristles of the cleaning brush 24 to always be in contact with the outer wall of the wire drawing, ensuring that it is suitable for wire drawing of different diameters.

[0046] There are four T-slots 21 , which are evenly arranged in the circumferential direction on the second rotating sleeve 20 , thereby increasing the number of cleaning brushes 24 and ensuring that debris is completely brushed away.

[0047] Through holes are provided at both ends of the dust removal housing 5, and a through hole is provided in the middle of the partition 12, and the through holes are used for the passage of the wire drawing. There are four spring sleeve rods 18, and the four spring sleeve rods 18 are evenly arranged in the circumferential direction on the second rotating sleeve 20. A through hole is provided inside the fixed plate 17 and located outside the spring sleeve rods 18. The spring sleeve rods 18 can realize the flexible installation of the second rotating sleeve 20 in the left and right directions. When the cleaning brush 24 contacts the wire drawing, the wire drawing is conveyed, which will generate friction on the cleaning brush 24, so that the cleaning brush 24 moves toward one side of the fixed plate 17. The horizontal movement of the cleaning brush 24 is limited by the spring sleeve rods 18. At the same time, according to the different conveying speeds of the wire drawing, the friction generated is also different, which will produce the effect of the cleaning brush 24 rotating and cleaning while moving in the left and right directions to further improve the cleaning effect of the outer wall of the wire drawing.

[0048] When the dust removal device for the wire drawing machine is used, one end of the wire drawing passes through the dust removal shell 5, the wire drawing die head 13 and the partition 12 and is fixed to the winding roller 2, and the winding roller 2 is driven to rotate by the winding motor 3 to provide the driving force required for wire drawing. During the wire drawing process, when the wire drawing passes through the wire drawing die head 13, the inner diameter of the end of the wire drawing die head 13 is slightly smaller than the diameter of the wire drawing, so that the diameter of the wire drawing is reduced after passing through the wire drawing die head 13. In the process of reducing the wire drawing diameter, debris will appear, and some of the debris will fall directly to the bottom of the dust removal shell 5, and some of the debris will accumulate at the port of the wire drawing die head 13. This part of the debris is blown by the negative pressure fan 10, and guided by the blowing pipe 9, so that the blowing head 27 blows toward the blades 15 outside the first rotating sleeve 14, thereby driving the blades 15 and the first rotating sleeve 14 to rotate, thereby driving the chip breaker 16 to rotate, and the debris accumulated at the end of the wire drawing die head 13 is cut off by the chip breaker 16 and falls to the bottom of the dust removal housing 5. The negative pressure suction of the negative pressure fan 10 makes the debris at the bottom of the dust removal housing 5 enter the ventilation housing 7, and finally enter the filter plate 11 inside the negative pressure housing 8 to store the debris;

[0049] Some of the debris will continue to move toward the winding roller 2 as the wire drawing moves. When this part of the debris passes through the cleaning brush 24, the blowing head 27 on the outside of the second rotating sleeve 20 blows air to the blades 15, causing the blades 15 and the second rotating sleeve 20 to rotate, thereby driving the cleaning brush 24 on the second rotating sleeve 20 to rotate, and the debris on the outside of the wire drawing is brushed off by the cleaning brush 24 to ensure that the debris on the wire drawing is cleaned and thoroughly cleaned. The cleaned debris also enters the top of the filter plate 11 through the ventilation shell 7. The entire dust removal device can use excess wind force to rotate and clean the wire drawing surface while removing dust through negative pressure, ensuring that the outer wall of the wire drawing is clean, improving the dust removal effect during the wire drawing process, and utilizing the wind force of negative pressure dust suction to save energy consumption.

[0050] Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative work shall fall within the scope of protection of the present invention.
