Description

Technical Field

[0001] This utility model belongs to the field of metal wire drawing lubricating powder production technology, and more specifically, it relates to a metal wire drawing lubricating powder conveying device. Background Technology

[0002] Metal wire drawing lubricant is a process lubricant used in the drawing process of metal wire. Its components typically include calcium hydroxide, sodium hydroxide, stearic acid, animal fats, vegetable oils, paraffin wax, industrial soap, talc, industrial alkali, etc. Its primary function is to form a lubricating film between the drawn metal wire and the drawing die wall, reducing interfacial friction and energy consumption during drawing; preventing the wire from sticking to the die wall due to heat, thus reducing energy consumption and temperature rise during drawing, extending the service life of the drawing die, and ensuring the surface quality of the wire. A secondary function is to ensure that the drawn wire possesses characteristics suitable for subsequent processing, such as the thickness of the residual lubricating film, ease of cleaning, rust prevention, adhesion to other media, and suitability for subsequent plating and welding processes.

[0003] However, in actual use, after the drawing lubricating powder is mixed and produced according to its raw material ratio, it is prone to clumping, which affects its conveying and makes it impossible to accurately control the supply. At the same time, the powder is exposed during operation, and the dust is seriously flying, which not only wastes raw materials, but also pollutes the environment and endangers the health of operators.

[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided a metal wire drawing lubricating powder feeding device in order to achieve a more practical purpose. Utility Model Content

[0005] To address the aforementioned technical problems, this utility model provides a metal wire drawing lubricating powder conveying device to solve the problems raised in the background art.

[0006] The purpose and effectiveness of this utility model's metal wire drawing lubricating powder conveying device are achieved through the following specific technical means:

[0007] A metal wire drawing lubricating powder conveying device includes a conveying mechanism, a crushing mechanism, and a discharging mechanism. The conveying mechanism includes a conveying cylinder with an inlet on one side of its upper end and a discharge outlet on the lower side of the other end. A crushing mechanism is located at the inlet, comprising rotating crushing blocks and fixed crushing blocks. Multiple fixed crushing blocks are equidistantly installed on both sides of the inlet, with rotating crushing blocks interspersed among the fixed crushing blocks. The rotating and fixed crushing blocks are used to crush agglomerated materials. A discharging mechanism is connected to the lower end of the discharge outlet. The discharging mechanism includes a discharge box with a discharge hopper at its lower end, and a solenoid valve is located at the outlet of the discharge hopper.

[0008] Furthermore, a No. 1 motor is provided at one end of the conveying cylinder, and a rotating shaft is connected to the output end of the No. 1 motor. The rotating shaft is installed inside the conveying cylinder, and a screw conveyor is arranged around the rotating shaft.

[0009] Furthermore, the screw conveyor is configured with a variable pitch, with a slightly larger pitch near the inlet and a slightly smaller pitch near the outlet, and the screw conveyor is fitted with a clearance fit to the inner wall of the conveying cylinder.

[0010] The beneficial effect of adopting the above-mentioned further solution is that the rotating shaft driven by the No. 1 motor drives the screw conveyor to transport materials. The screw conveyor with variable pitch facilitates better filling and stable extrusion pressure. In addition, the screw conveyor and the inner wall of the conveying cylinder are fitted with a gap, which not only prevents jamming but also effectively scrapes off the attached powder.

[0011] Furthermore, a material distribution device is provided on the discharge port. The material distribution device includes a second motor, which is installed at one end of the discharge port. The output end of the second motor is connected to a first drive gear, and a first driven gear is meshed on one side of the first drive gear.

[0012] Furthermore, a first rotating shaft and a second rotating shaft are respectively installed on the first driving gear and the first driven gear. Both the first rotating shaft and the second rotating shaft are equipped with a material leveling brush, and the two sets of material leveling brushes are staggered.

[0013] The beneficial effect of adopting the above-mentioned further solution is that the No. 2 motor drives the No. 1 drive gear to rotate, and the No. 1 driven gear rotates under the meshing transmission of the gears. The rotation direction is opposite to that of the No. 1 drive gear, thereby realizing that the No. 1 rotating shaft and the No. 2 rotating shaft drive the uniform brush to rotate in opposite directions, so that the falling powder is further dispersed and evenly sprinkled into the discharge box.

[0014] Furthermore, the crushing mechanism also includes a No. 3 motor, the output end of which is connected to a No. 2 drive gear. A No. 2 driven gear is provided on one side of the No. 2 drive gear. A No. 4 rotating shaft and a No. 3 rotating shaft are respectively connected to the No. 2 driven gear and the No. 2 drive gear. Multiple sets of rotating crushing blocks are provided at equal intervals on both the No. 4 rotating shaft and the No. 3 rotating shaft.

[0015] The beneficial effect of adopting the above-mentioned further scheme is that the No. 2 drive gear is driven by the No. 3 motor to rotate. Under the meshing transmission of the gears, the No. 2 driven gear rotates in the opposite direction, which in turn causes the No. 4 rotating shaft and the No. 3 rotating shaft to drive the rotating crushing blocks to rotate, thereby realizing the crushing and crushing between the two sets of rotating crushing blocks and between the two sets of rotating crushing blocks and the two sets of fixed crushing blocks, and crushing the agglomerated materials.

[0016] Furthermore, the top of the discharge box is provided with a through hole for sealing connection to the discharge port, the inside of the discharge box has a conical sidewall with an inclination angle greater than the angle of repose of the lubricating powder, and a dust collection mechanism is installed on the rear side of the discharge box.

[0017] The beneficial effects of adopting the above-mentioned further solution are that the conical sidewall design ensures that the powder can smoothly slide down under gravity and enter the discharge hopper for discharge. The dust collection mechanism creates negative pressure within the system, causing the airborne dust to be absorbed and collected. The sealed discharge box combined with the dust collection mechanism effectively solves the problem of airborne lubricating powder dust, improves the workshop working environment, and protects the health and safety of workers.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] This metal wire drawing lubricating powder conveying device uses a No. 3 motor to drive a No. 2 drive gear to rotate. Under the meshing transmission of the gears, the No. 2 driven gear rotates in the opposite direction, which in turn causes the No. 4 and No. 3 rotating shafts to drive the rotating crushing blocks to rotate. This achieves crushing and grinding between the two sets of rotating crushing blocks and between the two sets of rotating crushing blocks and two sets of fixed crushing blocks, thus crushing agglomerated materials. A No. 1 motor drives a rotating shaft to rotate and drive a screw conveyor to transport the material. The variable-pitch screw conveyor facilitates better filling and stable extrusion pressure, and the clearance fit between the screw conveyor and the inner wall of the conveying cylinder prevents jamming. The material effectively scrapes off adhering powder. After passing through the distribution device at the discharge port, the second motor drives the first drive gear to rotate. Under the meshing transmission of these gears, the first driven gear rotates in the opposite direction to the first drive gear. This causes the first and second rotating shafts to drive the equalizing brush to rotate in the opposite direction, further dispersing the falling powder and evenly distributing it inside the discharge box. The conical sidewalls of the discharge box ensure that the powder can smoothly slide down by gravity and be discharged into the discharge hopper. The discharge rate is controlled by a solenoid valve. A dust collection mechanism creates negative pressure within the system, causing the airborne dust to be absorbed and collected. The sealed discharge box, combined with the dust collection mechanism, effectively solves the problem of flying lubricating powder dust, improves the workshop working environment, and ensures the health and safety of workers.

[0031] A primary motor 104 is installed at one end of the conveying cylinder 101.

The screw conveyor 106 adopts a variable pitch setting, with a slightly larger pitch near the feed inlet 102 and a slightly smaller pitch near the discharge outlet 103. The screw conveyor 106 is clearance-fitted with the inner wall of the conveying cylinder 101. A material distribution device 107 is provided on the discharge port 103.

[0032] The crushing mechanism 200 also includes a third motor 201. The output end of the third motor 201 is connected to a second drive gear 202. A second driven gear 203 is provided on one side of the second drive gear 202.

Multiple sets of rotating crushing blocks 205 are equally spaced on the fourth rotating shaft 206 and the third rotating shaft 204.

[0033] The top of the discharge box 301 is provided with a through hole 302 that is sealed to the discharge port 103.

[0034] The specific usage and function of this embodiment are as follows:

[0035] When using this type of metal wire drawing lubricating powder conveying device, firstly, after the material enters the feed inlet 102, the No. 3 motor 201 drives the No. 2 drive gear 202 to rotate. Under the meshing transmission of the gears, the No. 2 driven gear 203 rotates in the opposite direction, which in turn drives the No. 4 rotating shaft 206 and the No. 3 rotating shaft 204 to rotate the rotating crushing blocks 205, realizing the crushing and crushing between the two sets of rotating crushing blocks 205 and between the two sets of rotating crushing blocks 205 and the two sets of fixed crushing blocks 207, thus crushing the agglomerated material.

The variable pitch screw conveyor 106 facilitates better filling and stable extrusion pressure, and the screw conveyor 106 and the inner wall of the conveying cylinder 101 are well-connected. The gap fit prevents jamming and effectively scrapes off the attached powder. The material passes through the distribution device 107 at the discharge port 103, and is driven by the second motor 1071 to rotate the first drive gear 1072. Under the meshing transmission of the gears, the first driven gear 1073 is driven to rotate, and the rotation direction is opposite to that of the first drive gear 1072. This causes the first rotating shaft 1074 and the second rotating shaft 1075 to drive the uniform brush 1076 to rotate in the opposite direction, so that the falling powder is further dispersed and evenly sprinkled into the discharge box 301. The discharge box 301 with a conical sidewall can ensure that the powder can slide smoothly down by gravity and enter the discharge hopper 303 for discharge. The discharge amount is controlled by the solenoid valve 304. The dust collection mechanism 305 generates negative pressure in the system, so that the flying dust is adsorbed and collected by the dust collection mechanism 305. The sealed discharge box 301, combined with the dust collection mechanism 305, effectively solves the problem of flying lubricating powder dust, improves the workshop working environment, and protects the health and safety of the staff.
