Description

Technical Field

[0001] The invention relates to the technical field of spring steel wire processing, and more specifically to a drying device for processing spring steel wire for automobiles. Background Art

[0002] Spring steel wire is a kind of steel wire used to make springs or steel wire parts. There are many types of springs according to their uses, such as spring steel wire for mattress springs, spring steel wire for shock absorbers, spring steel wire for engine valves, and spring steel wire for camera shutters. Spring steel wire can also be classified according to the manufacturing process, such as raw spring steel wire, lead quenched spring steel wire, galvanized spring steel wire, oil quenched spring steel wire, etc. Different types of spring steel wires have different production methods, but the common characteristics of different spring steel wires are that they all require certain strength, high toughness and good coiling performance. Therefore, the steel wire has high elastic limit, yield strength and tensile strength. It is widely used in the automotive field and is an indispensable part in automobile manufacturing. When spring steel wire is produced, it needs to be cleaned after grinding or quenching. The cleaned spring steel wire needs to be sent to a drying mechanism for drying to prevent the spring steel wire from rusting due to water vapor. However, the current spring steel wire is directly sent to the drying mechanism during drying. At this time, there is more moisture on the spring steel wire, which will increase the drying time, thereby increasing the working time and reducing the working efficiency. When the spring steel wire is being dried, it is easy to accumulate somewhere because the spring steel wire is thin. If the spring steel wire is accumulated, the spring steel wire at the accumulation place cannot be thoroughly dried, and there will still be water remaining in some parts of the spring steel wire after drying, which will eventually cause the spring steel wire to rust and become scrapped.

[0026] In the embodiment of the present application, when the conveyor belt 2 is conveying the spring steel wire, the water on the spring steel wire will flow downward through the conveyor belt 2, and the water under the drying blower 9 will flow to the top of the guide plate 3 when passing through the conveyor belt 2, and enter the water collecting trough 4 after passing through the guide plate 3, and the side of the guide plate 3 is located above the inside of the water collecting trough 4 to prevent the water from flowing to other positions, and the water entering the water collecting trough 4 will be discharged through the drain pipe 5 to prevent the water from accumulating in the drying box 1 for a long time and reducing the drying effect. In addition, the guide plate 3 will not affect the operation of the conveyor belt 2.

[0027] Reference Figure 3 , Figure 5 , Figure 5 as well as Figure 6The water wiping mechanism 6 includes a servo motor 601 for providing power, a bidirectional screw 602 is fixedly connected to the side of the servo motor 601, a fixed plate 603 is movably connected to the middle of the bidirectional screw 602, an arc-shaped sponge 607 is fixedly connected to the bottom end of the bidirectional screw 602, and an extrusion plate 606 is movably connected to both sides of the arc-shaped sponge 607, a moving block 604 is movably connected to both sides of the bidirectional screw 602, and a sealing plate 605 is fixedly connected to the bottom end of the moving block 604, and a delay spring 610 is movably connected to the sides of the two sealing plates 605 that are close to each other, and the side of the delay spring 610 away from the sealing plate 605 contacts the side of the extrusion plate 606, and the side of the sealing plate 605 close to the arc-shaped sponge 607 is fixedly connected to a limiting sleeve The cylinder 608, the limiting sleeve 608 is movably connected to the interior of the sealing plate 605 with a fixing rod 609, the side of the fixing rod 609 away from the limiting sleeve 608 is fixedly connected to the side of the extrusion plate 606, the side of the extrusion plate 606 away from the sealing plate 605 is adapted to the side of the arc sponge 607, and the two sealing plates 605 can contact each other when they move toward each other, and a drainage channel 612 is opened inside the drying box 1, and the top of the drainage channel 612 is in contact with the arc sponge 607. When the two sealing plates 605 are in contact, the arc sponge 607 and the top of the drainage channel 612 are sealed, and the side of the bidirectional screw 602 is movably connected to a fixing block 611, and the top of the fixing block 611 is fixedly connected to the top inside the drying box 1.

[0028] In the embodiment of the present application, when the spring steel wire passes through the arc sponge 607, the arc sponge 607 can absorb the moisture on the spring steel wire, and when there is more moisture in the arc sponge 607, the bidirectional screw 602 will rotate. When the bidirectional screw 602 rotates, the two moving blocks 604 and the sealing plate 605 below them move inward synchronously, and the sealing plate 605 moves directly inward, so the bottom ends of the two sealing plates 605 will contact, and the sealing plate 605 will compress the delay spring 610 when it moves. After the two delay springs 610 are compressed, they will drive the two extrusion plates 606 to move inward and compress the arc sponge 607, so the two sealing plates 605 are in contact with each other. When the bottom end of the sealing plate 605 contacts, the arc sponge 607 is located above the sealing plate 605. At this time, the bottom of the arc sponge 607 is sealed. After sealing, the squeezing plate 606 moves to squeeze the arc sponge 607. Therefore, the moisture in the squeezing plate 606 will only be discharged through the two ends. When the two ends are drained, the bottom is sealed by the sealing plate 605, and the water will only enter the drainage channel 612, and then enter the water collection tank 4 through the drainage channel 612, avoiding the problem that when the arc sponge 607 is directly squeezed, the water in the arc sponge 607 will be directly discharged downward, causing the spring steel wire to become wet, requiring more drying time.

[0029] Reference Figure 7 and Figure 8The sliding mechanism 7 includes a supporting sealing box 701, an output motor 702 is fixedly connected to the side of the sealing box 701, an output shaft 703 is fixedly connected to the side of the output motor 702, a rotating connecting rod 704 is fixedly connected to the side of the output motor 702, a swing rod 705 is movably connected to the side of the rotating connecting rod 704, a shaking sleeve 707 is movably connected to the bottom end of the shaking rod 705, a fixed shaft 706 is movably connected to the top of the shaking rod 705, both ends of the fixed shaft 706 are fixedly connected to the inside of the sealing box 701, a connecting plate 708 is fixedly connected to the bottom end of the side of the swing rod 705, a limiting rod 709 is movably connected to the inside of the connecting plate 708, the bottom end of the limiting rod 709 is fixedly connected to the top of the shaking sleeve 707, a supporting spring 710 is provided on the side of the limiting rod 709, and the supporting spring 710 is located between the connecting plate 708 and the shaking sleeve 707.

[0030] In the embodiment of the present application, when the rotating connecting rod 704 rotates, it will drive the swing rod 705 to swing around the fixed axis 706, and the swing rod 705 will drive the shaking sleeve 707 to swing. At this time, the shaking sleeve 707 will reciprocate above the conveyor belt 2, and the shaking sleeve 707 can move up and down on the side of the swing rod 705. Therefore, the shaking sleeve 707 can move to any position above the conveyor belt 2 and will not be unable to move. Therefore, when the shaking sleeve 707 reciprocates, the spring steel wire will be dispersed to improve the drying effect, and the shaking sleeve 707 itself is small, which will not affect the normal transportation of the spring steel wire and will not make the spring steel wire unable to move.

[0031] Reference Fig. 9 as well as Fig.10 The cleaning mechanism 8 includes a fixed support plate 801, and there are two support plates 801. The sides of the two support plates 801 that are close to each other are fixedly connected with square sponges 802. The top of the square sponge 802 contacts the bottom end of the conveyor belt 2. The sides of the square sponge 802 that are away from the support plate 801 are movably connected with a rotating plate 803. The inner movability of the side of the rotating plate 803 is connected with a support shaft 804. The side of the support shaft 804 is fixedly connected with the interior of the drying box 1. The side of the rotating plate 803 that is away from the square sponge 802 is movably connected with a trapezoidal block 805. The inner thread of the trapezoidal block 805 is connected with a threaded rod 806. One side of the threaded rod 806 is fixedly connected with a hand wheel 807, and the other side of the threaded rod 806 is movably connected with the interior of the drying box 1.

[0032] In the embodiment of the present application, the square sponge 802 will wipe away the moisture and impurities on the surface of the conveyor belt 2. When the handwheel 807 rotates, it drives the threaded rod 806 to rotate and causes the trapezoidal block 805 to move forward. When the trapezoidal block 805 moves, the rotating plate 803 moves toward the square sponge 802, thereby squeezing out the moisture in the square sponge 802. When the handwheel 807 moves in the opposite direction, the trapezoidal block 805 is reset, and the squeezed square sponge 802 is reset and the cleaning work is performed again.

[0033] The working principle of the present invention is as follows: the spring steel wire is placed on the conveyor belt 2 and is sent into the drying box 1 through the conveyor belt 2. When the spring steel wire passes through the arc sponge 607, the arc sponge 607 absorbs the moisture on the spring steel wire. The conveyor belt 2 then sends the spring steel wire to the bottom of the sliding mechanism 7. The output motor 702 in the sliding mechanism 7 is started and drives the output shaft 703 to rotate. When the output shaft 703 rotates, it drives the rotating connecting rod 704 to rotate. The rotating connecting rod 704 rotates to make the swing rod 705 swing around the fixed shaft 706. When the swing rod 705 swings, it drives the shaking sleeve 707 to swing above the spring steel wire. When the shaking sleeve 707 swings, it can move up and down on the outside of the swing rod 705 and compress the supporting spring 710 to ensure that the shaking sleeve 707 can disperse the spring steel wires at different positions. The dispersed spring steel wires are dried and sent out after passing through the bottom of the drying blower 9. When the water absorbed by the arc sponge 607 is large, the servo motor 601 starts and drives the bidirectional screw 602 to rotate. The rotation of the bidirectional screw 602 causes the two moving blocks 604 to move inward. The moving blocks 604 drive the sealing plates 605 to move inward. When the two sealing plates 605 move inward, the delay spring 610 is compressed. After the delay spring 610 is compressed, the extrusion plate 606 moves inward. The extrusion plate 606 moves with a delay relative to the sealing plate 605. When the two sealing plates 605 move inward, the bottoms of the two sealing plates 605 contact each other. At this time, the arc sponge 607 is opened. The arc sponge 607 is isolated at the top, and after the sealing plate 605 seals the bottom of the arc sponge 607, the squeezing plate 606 moves inward and squeezes the arc sponge 607. The water in the arc sponge 607 is only discharged into the drainage channel 612 through the two ends of the arc sponge 607, so as to prevent the water from falling directly to the bottom, so that the spring steel wire is stained with water and the drying effect is reduced. After the arc sponge 607 is drained, the servo motor 601 controls the drainage channel 612 to reverse, and at this time, the two sealing plates 605 are reset, and the squeezed arc sponge 607 is reset to reset the squeezing plate 606; When the conveyor belt 2 passes the cleaning mechanism 8, it will return to the top again to transport the spring steel wire. Therefore, the square sponge 802 in the cleaning mechanism 8 will wipe off the moisture and impurities on the surface of the conveyor belt 2. Although the water above will pass through the conveyor belt 2 and fall onto the cleaning mechanism 8 and the lower surface of the conveyor belt 2, the square sponge 802 can still wipe off part of the moisture, thereby solving the problem of the traditional conveyor belt 2 having more moisture when it is transported again, and wiping off the impurities on the conveyor belt 2 to avoid clogging the drainage holes in the conveyor belt 2 when the impurities are transported to the inside of the drying box 1 again. When the square sponge 802 absorbs more water, turn the hand wheel 807. When the hand wheel 807 rotates, it drives the threaded rod 806 to rotate and makes the trapezoidal block 805 move forward. When the trapezoidal block 805 moves, the rotating plate 803 moves toward the square sponge 802, thereby squeezing out the moisture in the square sponge 802.

[0034] Finally: The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
