Description

Technical Field

[0001] The utility model belongs to the technical field of automobile bumper production, and relates to a dust blowing system and an automobile bumper dust blowing device. Background Art

[0002] The car bumper is a safety device that absorbs and mitigates external impact and protects the front and rear parts of the car body. Many years ago, the front and rear bumpers of cars were stamped into channel steel with steel plates, riveted or welded to the longitudinal beams of the frame, and had a large gap with the car body, which looked very unsightly. With the development of the automobile industry and the extensive application of engineering plastics in the automobile industry, the car bumper, as an important safety device, has also taken the road of innovation. In addition to maintaining the original protection function, the front and rear bumpers of today's cars also pursue harmony and unity with the body shape and pursue their own lightweight. The front and rear bumpers of cars are made of plastic, which people call plastic bumpers. The plastic bumper of a general car is composed of three parts: outer plate, buffer material and crossbeam. Among them, the outer plate and buffer material are made of plastic, and the crossbeam is stamped into a U-shaped groove with cold-rolled thin plates; the outer plate and buffer material are attached to the crossbeam.

[0003] At present, it is found in the production process of bumpers that dust and other impurities are easily adhered to the surface of the bumpers. Therefore, corresponding dust blowing devices are usually set during the transportation of the bumpers (for example, conveyor belts or conveyor rollers are usually used for transmission when transferring between different workstations) (the corresponding positions and quantities are set according to actual conditions, not just one place) to blow dust off the surface of the bumper. However, since the position of the dust blowing outlet is fixed, but the shape of the bumper is relatively special, it is easier to cause dead angles or blind spots for dust blowing, resulting in poor dust blowing and cleaning effect.

[0064] The utility model also provides a dust blowing device for a car bumper, comprising the dust blowing system as described in any one of the above items.

[0065] The dust blowing system provided by the utility model, when blowing dust to a cleaning object (preferably a car bumper in this application, and the bumper is taken as the cleaning object hereinafter, but it is not limited to the bumper in actual use), firstly, the bumper is transported by a conveyor belt, etc., and passes through the U-shape with an opening downward formed by the horizontal frame body 1 and the vertical frame body 2; when the bumper passes between the horizontal frame body 1 and the vertical frame body 2, the outside of the blower rod 5 is connected to the blower, etc., so that high pressure is formed in the blower rod 5, and the high-pressure air enters the dust blowing rod 4 and is finally ejected through the dust blowing head 6 and acts on the bumper, so that the bumper can be cleaned; at the same time, during the cleaning process, the driving mechanism drives the movable block 3 to move, specifically, the movable block 3 on the vertical frame body 2 is vertically lifted and lowered, so that a bumper with a larger height range can be cleaned; at the same time, the movable block 3 on the horizontal frame body 1 reciprocates horizontally, so that the width direction of the bumper can also be comprehensively cleaned, which can make the cleaning more comprehensive and the effect better. It should also be understood that when blowing dust off the same bumper, several groups of horizontal frames 1 and vertical frames 2 can be selected for cleaning, and during actual cleaning, the activity cycle and speed of the movable block 3 can be adaptively adjusted according to the actual bumper or other cleaning object. For example, if the left side of the bumper is relatively smooth, the air pressure requirement for blowing air and the activity requirement of the movable block 3 are lower. If the right side has a frosted texture or a more complex intersection, a larger blowing air pressure is required, and the activity requirement of the movable block 3 is also higher.

[0066] In actual use, multiple dust blowing rods 4 at the same place are only connected to one blowing rod 5, so that the structure of the dust blowing equipment is simpler and the cost is lower. Secondly, the distance between the dust blowing head 6 and the bumper can also be better adjusted; secondly, the dust blowing head 6 is flat, so the speed of air outflow can be increased, and the dust blowing effect is stronger; secondly, the dust blowing range is wide, so the cleaning effect is better.

[0067] When the movable block 3 is moving, the driving motor 12 drives the driving screw 11 to rotate, and the driving screw 11 drives the linkage part 9 to move; at the same time, since the two sides of the movable block 3 are engaged in the sliding groove 8 through the sliding part 7, the activity stability of the movable block 3 can be improved.

[0068] Since different bumpers have differences in size, shape, production process, factory environment, etc., the optimal position of the dust blower head 6 is also different for different bumpers. For example, for smaller or dustier bumpers, the distance between the dust blower head 6 and the bumper needs to be smaller; but if the bumper is too large, or the cleaning area required is larger, the distance between the dust blower head 6 and the bumper needs to be larger. Therefore, the position of the dust blower head 6 and the dust blower rod 4 needs to be adjusted according to the actual situation.

[0069] During adjustment, the rotating handle 42 is first rotated, so that the rotating handle 42 drives the rotating disk 21 to rotate through the extension portion 41 and the extension cover 40, and the second elastic member 39 is further compressed in the process until the end of the movable opening 36 contacts the positioning seat 37, at which time the first clearance opening 24 is aligned with the first clearance groove 22, and the second clearance opening 25 is aligned with the second clearance groove 23;

[0070] Then, the first operating handle 27 is rotated upward, and the first operating handle 27 drives the semi-elliptical first eccentric member 26 to rotate upward until the magnetic portion 34 on the first eccentric member 26 is magnetically attracted to the corresponding temporary portion 35; then, the worker bends the unlocking portion 45 outward, and the unlocking portion 45 drives the outer side of the temporary member 43 to separate from the extension portion 41, and then pulls the second operating handle 29 outward until the magnetic portion 34 on the second eccentric member 28 is magnetically attracted to the corresponding temporary portion 35; then, the rotating handle 42 is released;

[0071] At this time, under the elastic force of the first elastic member 33, the movable plate 15 moves outward, and during the outward movement, the magnetic portion 34 and the temporary portion 35 can slide relative to each other, that is, the two are not in a clamped or fixed state; the movable plate 15 moves outward until the outer side of the movable plate 15 contacts the anti-slip disk 31 (the actual movement distance of the movable plate 15 is small), and at this time, the first positioning half groove 14 and the second positioning half groove 17 are in a slightly separated state, and the position of the dust blowing rod 4 can be adjusted along the length direction of the dust blowing rod 4, and the dust blowing head 6 can reach a suitable position; in the process of adjusting the dust blowing rod 4, the first positioning half groove 14 and the second positioning half groove 17 still support the dust blowing rod 4 to prevent it from falling;

[0072] When the dust blowing head 6 is in the right position, the rotating handle 42 is rotated until the first clearance opening 24 is aligned with the first clearance groove 22 (i.e., one side of the movable opening 36 abuts against the positioning seat 37), and then the second operating handle 29 is first rotated toward the positioning platform 20. When the second operating handle 29 passes through the second clearance opening 25, the outer side of the extension 41 abuts against the outer side of the temporary member 43, and drives the temporary member 43 to undergo elastic deformation until the end of the second operating handle 29 is just engaged in the second clearance groove 23. At this time, the temporary member 43 just passes over the extension 41, and then the temporary member 43 is returned. The second elastic member 39 is used to elastically release the free end of the temporary member 43 and cause the free end of the temporary member 43 to abut against the inner side of the extension portion 41. At this time, the second operating handle 29 can be no longer operated, and only the first operating handle 27 needs to be rotated. When the first operating handle 27 is rotated, it can be directly rotated, and the free end of the first operating handle 27 is inserted into the second making way groove 23 after passing through the second making way opening 25. At this time, the rotating handle 42 is released, and the rotating disk 21 is rotated under the elastic force of the second elastic member 39 until the positioning seat 37 abuts against the other end of the movable opening 36. At this time, the positioning of the first operating handle 27 and the second operating handle 29 is completed.

[0073] At this time, the outer sides of the first operating handle 27 and the second operating handle 29 are limited by the rotating disk 21, and the sides are limited by the first make way groove 22 and the second make way groove 23, so the positions of the first operating handle 27 and the second operating handle 29 are stable. At the same time, the first operating handle 27 and the second operating handle 29 drive the movable plate 15 toward the movable block 3 through the first eccentric member 26 and the second eccentric member 28 to move, and make the rotating seat 38 and the fixed seat 13 approach each other, and finally clamp the corresponding dust blowing rod 4 in place through the first positioning half groove 14 and the second positioning half groove 17; according to actual conditions, a rubber layer or a silicone layer can be provided on the inner walls of the first positioning half groove 14 and the second positioning half groove 17 to improve the position stability.

[0074] During subsequent use, due to the presence of the second elastic member 39, the rotating disk 21 can always maintain its position stable, so the pressure on the movable plate 15 is also stable; at the same time, when the second elastic member 39 drives the rotating disk 21 to rotate, the end of the temporary member 43 connected to the second operating handle 29 can be inserted into the card entrance 44, thus ensuring that the rotating disk 21 can rotate normally.

[0075] At the same time, when operating the second operating handle 29, the worker fixes the rotating handle 42 with one hand and operates the second operating handle 29 with the other hand, so that normal operation can be performed at this time; and after the temporary part 43 fixes the second operating handle 29, the other hand can continue to operate the first operating handle 27, so that the whole process can be performed by only one worker, and the operation is more convenient.

[0076] The above description is only a description of the preferred embodiment of the utility model, and is not any limitation on the scope of the utility model. Any changes and modifications made by ordinary technicians in the field of the utility model based on the above disclosure shall fall within the scope of protection of the claims.
