Description

Technical Field

[0001] The invention relates to the technical field of spraying devices, in particular to a spraying device for producing rust-proof bolts on mining machinery. Background Art

[0002] When mining machinery is in use, most of it is directly exposed to the outside. In order to prevent the bolts on the mining machinery from loosening due to rust, it is necessary to carry out rust-proof treatment on the bolts during production. The common method is to spray anti-rust paint, which requires the use of a spraying device.

[0003] During use, most of the existing spraying devices are just a combination of a spray head and a rotating frame. When in use, the bolts are fixed on the rotating frame, and the rotating frame rotates to drive the bolts to change positions, thereby achieving the effect of spraying multiple bolts. When this method is used, the clamping tool will fit the side wall of the bolt, so during the spraying process, the clamping part cannot be sprayed, making the spraying not comprehensive enough. At the same time, most of the existing spray heads can only be raised and lowered, so they cannot spray the inner wall of the bolt thread, affecting the spraying effect of the bolt. Although the spray head can be coordinated with a manipulator so that the spray head can be tilted, the manipulator is generally expensive, not suitable for small-scale production, and not conducive to corporate competition.

DETAILED DESCRIPTION

[0029] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings.

[0030] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0031] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor is it a separate or selective embodiment that is mutually exclusive with other embodiments.

[0032] Example 1

[0033] Reference Figure 1 to Figure 6 , which is the first embodiment of the present invention, and provides a spraying device for producing anti-rust bolts on mining machinery, which can achieve the effect of conveniently spraying the inner wall of the bolt thread, and includes a supporting component 100, including an installation box 101, a motor 102 arranged in the installation box 101, a ring 103 arranged on the installation box 101, a protective ring 104 arranged on the ring 103, a rotating shaft 105 arranged on the motor 102, and a spray head 106 arranged outside the installation box 101; a spraying component 200, including a spray head 106 arranged on the rotating shaft 105 A placement component 201, an inclination angle changing component 202 arranged on the placement component 201, a transmission component 203 arranged on the placement component 201, a power component 204 arranged on the ring 103, and a one-way component 205 arranged on the power component 204; a transposition component 300, including a pushing component 301 arranged on the lower side of the placement component 201, a replenishing component 302 arranged on the pushing component 301, a limiting component 303 arranged on the pushing component 301, and a resetting component 304 arranged on the placement component 201.

[0034] Specifically, the output shaft of the motor 102 here passes through the installation box 101, the upper end of the rotating shaft 105 extends to the outside of the ring 103, and a gap is left between the inner wall of the protective ring 104 and the rotating shaft 105, so as not to block the movement of the rotating shaft 105. The nozzle 106 here can move up and down, so that multiple bolts can be sprayed.

[0035] Furthermore, the placement component 201 includes a plurality of U-shaped frames 201a fixedly connected to the rotating shaft 105, a plurality of cross plates 201b are fixedly connected to the plurality of U-shaped frames 201a, a load-bearing ring 201c is provided on the outer side of the plurality of cross plates 201b, and a transmission belt 201d is provided on the inner wall of the load-bearing ring 201c; the inclination angle changing component 202 includes an inner groove 202a arranged on the cross plate 201b, a transmission shaft 202b is rotatably connected in the inner groove 202a, a U-shaped connecting frame 202c is fixedly connected to the transmission shaft 202b, a threaded hole 202d is provided on the connecting frame 202c, and a screw 202e threadedly connected to the threaded hole 202d is fixedly connected to the load ring 201c.

[0036] Among them, the fact that the transmission belt 201d here can rotate is a prior art and will not be elaborated here. The specific implementation method can be provided with a chamber in the carrying ring 201c, and a power source (such as a motor) is arranged in the chamber, and then the power source drives the friction roller to rotate, and finally drives the transmission belt 201d to rotate. The transmission belt 201d here is in contact with the side wall of the bolt, so that when the transmission belt 201d rotates, it can drive the bolt to rotate by itself. At the same time, the wires of the electrical appliances here need to be arranged to avoid wire entanglement. This is a prior art and will not be elaborated here.

[0037] Preferably, the transmission assembly 203 includes a receiving groove 203a arranged in the horizontal plate 201b, the transmission shaft 202b passes through the receiving groove 203a and the horizontal plate 201b and is rotatably connected to the horizontal plate 201b, the transmission shaft 202b is fixedly connected with a gear 203b, the receiving groove 203a is slidably connected with a slider 203c, the slider 203c is fixedly connected with a U-shaped transmission frame 203d, the transmission frame 203d is fixedly connected with a toothed plate 203e meshing with the gear 203b, and the transmission frame 203d is elastically connected to the inner wall of the receiving groove 203a through a first spring 203f. The power assembly 204 includes a through opening 204a provided on a U-shaped frame 201a, the accommodating groove 203a is connected to the through opening 204a, a lifting plate 204b is slidably connected in the through opening 204a, a top block 204c is fixedly connected to the lifting plate 204b, a cutting edge 204d is provided on the top block 204c and the slider 203c, a first arc opening 204e is provided on the lifting plate 204b, a transverse opening 204f is provided on the first arc opening 204e, a second arc opening 204g is provided on the transverse opening 204f, and the first arc opening 204e and the second arc opening 204g are symmetrically arranged.

[0038] It should be noted that in the initial position, the middle part of the tooth plate 203e is meshed with the gear 203b, so that the tooth plate 203e can drive the gear 203b to rotate when moving outward or inward. When the slider 203c abuts against the top block 204c, the slider 203c moves outward. The first spring 203f is in a compressed state in the initial position, so that when the slider 203c is opposite to the horizontal opening 204f, the slider 203c can enter the horizontal opening 204f, causing the tooth plate 203e to move inward.

[0039] When in use, the nozzle 106 here can be raised and lowered, but the nozzle 106 does not need to be deflected or changed in inclination. At the same time, in order to speed up the spraying speed, two or even three nozzles 106 can be set to spray together. First, multiple bolts are placed in the load-bearing ring 201c, so that the side walls of the bolts are against the transmission belt 201d, and the lower end faces of the bolt nuts are against the upper end faces of the load-bearing ring 201c. Then, the motor 102 is started to rotate the rotating shaft 105, driving the multiple U-shaped frames 201a to rotate, so that a bolt on a U-shaped frame 201a is directly opposite to the nozzle 106, and then the bolt directly opposite to the nozzle 106 is rotated. The transmission belt 201d in the bearing ring 201c on the U-shaped frame 201a rotates, driving the bolt to rotate. At this time, the nozzle 106 sprays out the anti-rust paint to carry out anti-rust spraying. With the rotation of the bolt and the up and down movement of the nozzle 106, the side wall of the nozzle 106 can be sprayed. When the bolt needs to be tilted, it is only necessary to let the lifting plate 204b move downward. When the lifting plate 204b moves downward, it can drive the top block 204c to move downward. When the top block 204c is against the slider 203c, it can push the slider 203c to move outward, so that the slider 203c drives the transmission frame 203d to move outward, so that the tooth plate 20 3e moves outward, driving the gear 203b to rotate counterclockwise, thereby the transmission shaft 202b rotates counterclockwise, driving the connecting frame 202c to rotate counterclockwise around the transmission shaft 202b, causing the bearing ring 201c to deflect, thereby causing the bolt to deflect, so that an angle is formed between the bolt and the spray head 106, which is convenient for spraying the bottom of the inner thread of the bolt. As the lifting plate 204b continues to move downward, the slider 203c separates from the top block 204c. At this time, under the action of the first spring 203f, the transmission frame 203d is partially reset, and the transmission shaft 202b is reset to the initial position. At this time, the bolt is in a vertical state, and then as the lifting plate 204b continues to move downward, the slider 203c is separated from the top block 204c. At this time, under the action of the first spring 203f, the transmission frame 203d is partially reset, and at this time, the transmission shaft 202b is reset to the initial position. At this time, the bolt is in a vertical state, and then The lowering plate 204b continues to move downward, and the slider 203c moves into the first arc-shaped opening 204e. At this time, under the action of the first spring 203f, the slider 203c continues to move inward, and as the lifting plate 204b continues to descend, the slider 203c moves into the horizontal opening 204f. At this time, the tooth plate 203e drives the gear 203b to rotate clockwise, so that the transmission shaft 202b rotates clockwise. Through transmission, the bolt is deflected, and the deflection direction is opposite to that when the slider 203c moves outward, making it convenient to spray the top of the thread on the bolt. The setting of the third arc-shaped opening here facilitates the separation of the slider 203c from the horizontal opening 204f.

[0040] In summary, by setting up the spraying component 200 and utilizing the lifting and lowering of the lifting plate 204b, the slider 203c is moved inward or outward, and the driving ring 103 is tilted by the transmission belt 201d, so that the bolt is tilted, so that an angle is formed between the bolt and the nozzle 106, which facilitates the spraying of the inner wall of the thread on the bolt.

[0041] Example 2

[0042] Reference Figure 1 to Figure 10 , which is the second embodiment of the present invention. Different from the previous embodiment, this embodiment provides a one-way component 205 of a spraying device for producing rust-proof bolts on mining machinery, which solves the problem of how to provide power for the lifting of the lifting plate 204b. It includes a one-way component 205, including four first arc grooves 205a arranged on the ring 103, the upper first arc groove 205a is connected to the lower first arc groove 205a through the second arc groove 205b, and the lowermost first arc groove 205a is connected to the lower first arc groove 205a through the third arc groove. The groove 205c is connected to a first arc groove 205a at the upper end, and a supporting groove 205d is provided on the side wall of the third arc groove 205c. A supporting column 205e is rotatably connected in the supporting groove 205d, and a blocking piece 205f is fixedly connected to the supporting column 205e. A torsion spring 205g is provided on the supporting column 205e, and one end of the blocking piece 205f away from the second arc groove 205b is close to the inner wall of the supporting groove 205d. A guide column 205h that cooperates with the first arc groove 205a is fixedly connected to the lifting plate 204b.

[0043] Specifically, here the width of the top block 204c is equal to the height difference between the two first arc-shaped grooves 205a, the sum of the heights of the first arc-shaped opening 204e and the horizontal opening 204f is equal to the height difference between the two first arc-shaped grooves 205a, the lowermost first arc-shaped groove 205a is connected to the upper first arc-shaped groove 205a through the third arc-shaped groove 205c, and when the guide column 205h moves from the lowermost first arc-shaped groove 205a to the upper arc-shaped groove, the output shaft of the motor 102 rotates in the opposite direction, so that the guide column 205h can return to the uppermost first arc-shaped groove 205a.

[0044] When in use, the output shaft of the motor 102 rotates, driving the rotating shaft 105 to rotate, so that the multiple U-shaped frames 201a rotate, so that the bolts on different U-shaped frames 201a are aligned with the spray head 106, and multiple bolts are sprayed. When the multiple U-shaped frames 201a rotate, the guide column 205h first moves in the first arc groove 205a. When it is about to move to a complete ring, the guide column 205h moves into the second arc groove 205b, and moves from the second arc groove 205b to the first arc groove 205a at the lower end. The guide column 205h continues to move downward, driving the lifting plate 204b. At this time, the slider 203c is against the top block 204c, and then continues to slide in the first arc groove 205a of the second layer. Similarly, when it is about to move to a complete ring, it moves to the first arc groove 205a of the third layer through the second arc groove 205b. At this time, the guide column 205h continues to move downward. 205c, and the guide column 205h returns to the first arc groove 205a of the third layer. Then the motor 102 is reversed, so that the guide column 205h can be reset to the first arc groove 205a, thereby performing the lifting and lowering movement of the lifting plate 204b. The transmission provides power for the inclination of the bolt. When moving from the first arc groove 205a of the third layer to the first arc groove 205a of the bottom layer, the end of the baffle 205f away from the second arc groove 205b is close to the inner wall of the support groove 205d, so that the baffle cannot flip toward the third arc groove 205c, ensuring that it can move from the first arc groove 205a of the third layer to the first arc groove 205a of the bottom layer when moving downward. When the bottom moves upward, the baffle will not block it.

[0045] In summary, by setting the one-way component 205, when the output shaft of the motor 102 rotates the rotating shaft 105 and drives the multiple U-shaped frames 201a to move, it can also drive the lifting plate 204b to reciprocate and provide power for the tilting of the bolt, without the need for external power, and is more convenient to use.

[0046] Example 3

[0047] Reference Figure 1 to Figure 9, which is the third embodiment of the present invention. Different from the previous embodiment, this embodiment provides a displacement component 300 of a spraying device for producing rust-proof bolts on mining machinery, which solves the problem of how to spray nuts on bolts. It includes a pushing component 301, including a vertical groove 301a arranged on the inner wall of the through-hole 204a, a moving plate 301b cooperating with the top block 204c is slidably connected in the vertical groove 301a, and the moving plate 301b is elastically connected to the inner wall of the vertical groove 301a through a second spring 301c. The moving plate A pull rope 301d is fixedly connected to 301b, a circular opening 301e is provided on the U-shaped frame 201a for the pull rope 301d to pass through, a guide seat 301f for guiding the pull rope 301d is fixedly connected to the U-shaped frame 201a, and a push plate 301g is fixedly connected to the end of the pull rope 301d; the replacement component 302 includes a first arc-shaped piece 302a and a second arc-shaped piece 302b fixedly connected to the push plate 301g, and the first arc-shaped piece 302a and the second arc-shaped piece 302b are symmetrically arranged at both ends of the supporting ring 201c.

[0048] Specifically, when the slider 203c abuts against the inner wall of the second arc-shaped opening 204g, the top block 204c abuts against the movable plate 301b, and then as the lifting plate 204b moves downward, the top block 204c is driven downward, causing the movable plate 301b to move downward. When the guide column 205h moves into the first arc-shaped groove 205a at the lower end, the top block 204c moves downward to the extreme position, and the movable plate 301b also moves to the downward extreme position at this time.

[0049] Furthermore, the limiting assembly 303 includes a bayonet 303a arranged on the movable plate 301b, a guide opening is arranged on the side wall of the vertical slot 301a, a wedge block 303b cooperating with the bayonet 303a is slidably connected in the guide opening, a sliding sleeve 303c cooperating with the wedge block 303b is fixedly connected to the U-shaped frame 201a through a connecting rod, a U-shaped supporting frame 303d is fixedly connected to the rear end of the sliding sleeve 303c, and the wedge block 303b is elastically connected to the inner wall of the supporting frame 303d through a third spring 303e; the reset assembly 30 The strip-shaped opening 304a is provided on the wedge-shaped block 303b, an inclined groove 304b is provided on the inner wall of the strip-shaped opening 304a, a square strip 304c is provided on the lower side of the inclined groove 304b, the square strip 304c penetrates the U-shaped frame 201a and is slidably connected to the U-shaped frame 201a, a turning plate 304d is fixedly connected to the square strip 304c, a stop plate 304e matched with the turning plate 304d is fixedly connected to the lifting plate 204b, and the turning plate 304d is elastically connected to the bottom of the U-shaped frame 201a through a fourth spring 304f.

[0050] It should be noted that the setting of the wedge block 303b avoids the phenomenon of jamming between the movable plate 301b and the wedge block 303b, and when the movable plate 301b moves to the extreme position, the wedge block 303b is opposite to the bayonet 303a, blocking the reset of the movable plate 301b, and the square bar 304c cooperates with the inclined groove 304b to push the wedge block 303b to move outward.

[0051] When in use, when the guide column 205h moves from the first arc groove 205a of the third layer to the lowermost arc groove, the lifting plate 204b continues to move downward. At this time, the lifting plate 204b pushes the moving plate 301b to move downward, and the second spring 301c is compressed. When the moving plate 301b moves downward, the push plate 301g can be pulled by the pull rope 301d. The setting of the guide seat 301f can turn the pull rope 301d, so that when the moving plate 301b moves downward, the push plate 301g moves upward, so that the push plate 301g pushes the bolt upward, so that a gap is left between the nut of the bolt and the load-bearing ring 201c. During the process, the movable plate 301b pushes the wedge block 303b to move the wedge block 303b toward the outer end, and the third spring 303e obtains elasticity. Then, when the guide column 205h slides in the first arc groove 205a at the lower end, the bayonet 303a is directly opposite to the wedge block 303b. At this time, under the action of the third spring 303e, the bayonet block is stuck in the bayonet 303a to block the reset of the movable plate 301b. The guide column 205h will finally enter the third arc groove 205c, and then enter the second arc groove 205b along the third arc groove 205c. At this time, the motor 102 is reversed, so that the guide column 205h moves along the second arc groove 205c. 05b returns to the first arc groove 205a of the third layer, and then finally resets to the first arc groove 205a at the top. In this process, the lifting plate 204b will reset. During the resetting process of the lifting plate 204b, it passes through the first arc grooves 205a of the middle two layers, so that the bolt will tilt, which is convenient for spraying the nut on the bolt and avoids that some places cannot be sprayed. During the rising process of the lifting plate 204b, since the wedge block 303b is always in the bayonet 303a, the moving plate 301b is blocked from resetting, so that the push plate 301g is always against the bolt. When the bolt is tilted, the first arc piece 302a and the second arc piece 302a are 02b is against the bottom of the bolt to prevent the bolt nut from being against the load ring 201c again when the bolt is tilted. When the lifting plate 204b is reset to its original position, the stop plate 304e pushes the turning plate 304d, so that the square bar 304c moves upward. When the square bar 304c is against the inclined groove 304b, it continues to move upward. At this time, the square bar 304c can push the wedge block 303b to move outward, so that the wedge block 303b is separated from the bayonet 303a. Under the action of the second spring 301c, the moving plate 301b is reset, and the pull rope 301d is used to reset the push plate 301g to leave a gap with the lower end of the bolt for next use.

[0052] In summary, by setting the displacement component 300, the bolt can be automatically lifted up when the lifting plate 204b moves downward, so that a gap is left between the nut of the bolt and the supporting ring 201c, which is convenient for spraying the nut and makes the bolt sprayed more forward, resulting in a better spraying effect.
