DETAILED DESCRIPTION

[0036] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art without creative work fall within the protection scope of the present application.

[0037] In order to clearly describe and understand the patent, in addition to the tooling designed in the patent, the structures of other tooling and part of the structures of the equipment are also given in the drawings.

[0038] Embodiment 1

[0039] Please refer to Figures 1-6 , the automatic brush equipment for hub paint removal, comprising:

[0040] The rack 1 and the mounting frame 11 are fixedly installed on the upper end of the rack 1 through the support rod. The two ends of the rack 1 are respectively the input end and the output end. The hub enters the rack 1 from the input end and is output from the output end. The rack 1 adopts a frame structure. The four sides and the bottom can be provided with plate members. Among them, the plate members vertically arranged along the length direction of the two sides are installed in a hinged manner to realize opening and closing.

[0041] Please refer to Figure 2 , Figure 5 The lower brush assembly 2 is arranged on the rack 1. A plurality of lower brush assemblies 2 are arranged in sequence along the length direction of the rack 1. The lower brush assembly 2 comprises a first rotating shaft 21 and a first disc brush 22. Both ends of the first rotating shaft 21 are rotatably connected with the rack 1. At least one first disc brush 22 is fixedly arranged on the outer wall of the first rotating shaft 21.

[0042] Please refer to Figure 3 , Figure 6 The side brush assembly 3 is arranged in sequence along the direction of movement of the hub. The side brush assembly 3 comprises a second rotating shaft 31 and a second disc brush 32. One end of the second rotating shaft 31 is rotatably installed on the mounting frame 11 or the rack 1. At least one second disc brush 32 is fixedly arranged on the outer wall of the second rotating shaft 31.

[0043] The arrangement of the side brush assembly 3 is divided into two kinds, one of which is to arrange a plurality of side brush assemblies 3 on the same side of the hub moving direction, and to arrange the first rotating shaft 21 of the lower brush assembly 2 at an angle, and the plurality of side brush assemblies 3 are arranged at the lower end of the first rotating shaft 21. After the hub enters the rack 1, it slides to the direction of the side brush assembly 3 under the action of gravity, so that the side of the hub is tightly attached to the second disc brush 32, ensuring the effect of side paint removal. The inclination angle of the first rotating shaft 21 is generally set to 15-45 degrees, preferably 30 degrees. (When the inclination angle is small, the tightness of the hub and the second disc brush 32 is not enough, resulting in poor side paint removal effect. When the inclination angle is too large, the tightness of the hub and the first disc brush 22 is small, which can cause poor bottom paint removal effect). It is worth noting that the rotating direction of the second rotating shaft 31 should be consistent with the moving direction of the hub, so as to avoid the force of the second disc brush 32 acting on the side of the hub and the force of the first disc brush 22 acting on the hub.

[0044] The first rotating shaft 21 is arranged at an angle in this scheme, so as to ensure full contact between the hub and the second disc brush 32 by utilizing the action of gravity, and the hub is rotated by the rotating second disc brush 32, which can ensure that there is no dead angle in the side paint removal. This scheme is simple and ingenious, and can realize side paint removal without dead angle, and can also be applied to hubs of different diameters. However, in order to ensure the effect of side paint removal, the rack 1 needs to be appropriately lengthened, and more side brush assemblies 3 need to be used.

[0045] Another way is to arrange a plurality of brush assemblies 3 on both sides of the hub moving direction, and the rotating directions of the second rotating shafts 31 of the two groups of side brush assemblies 3 are consistent, and the second disc brushes 32 on both sides are tightly attached to the side of the hub. On the one hand, it can limit the position of the hub in the width direction of the rack 1, and on the other hand, the second disc brushes 32 on both sides can tightly contact the side of the hub, and can drive the hub to rotate, which can realize side paint removal while ensuring that there is no dead angle in side paint removal.

[0046] This scheme has high efficiency in side paint removal, but can only process hubs of the same diameter. Obviously, compared with the first scheme, this scheme has a complex structure and a smaller application range.

[0047] In order to improve its scope, the corresponding adjusting mechanism is arranged on the side brush assembly 3, which can be realized in a manual or automatic manner, and the relative movement of the side brush assembly 3 can be realized by the cooperation of the sliding block and the sliding rail. By adopting the manual adjusting mechanism, the second rotating shaft 31 can be fixed or loosened relative to the rack 1 or the mounting frame 11 through the design of buckles or limiting structures, so as to adjust the distance between the two groups of side brush assemblies 3; by adopting the automatic adjusting mechanism, one of the hydraulic cylinder, the air cylinder and the electric cylinder is used to cooperate with the corresponding automatic control system and the visual recognition device to realize the adjustment. The visual recognition device identifies the diameter and height of the hub, and adjusts the distance between the two groups of side brush assemblies according to the setting through any one of the hydraulic cylinder, the air cylinder and the electric cylinder and the servo mechanism.

[0048] As a further scheme, the input roller 14 and the output roller 15 are also arranged, and the input roller 14 and the output roller 15 are arranged at the input end and the output end of the rack 1 respectively. The input roller 14 and the output roller 15 adopt the prior art, and both of them include a plurality of rotating rollers which are synchronously rotated by means of chains or toothed belts. The driving mode adopts a motor, and the transmission structure adopts a gear set or a sprocket and a chain.

[0049] As a further scheme, the dust removal system 16 is also arranged, and the dust removal system 16 includes a plurality of dust collectors 161 which are arranged in sequence along the moving direction of the hub. The dust collector 161 can be arranged on the upper side, the lower side or both sides of the lower brush assembly 2. The collecting port of the dust collector 161 is communicated with a negative pressure device (such as a vacuum pump) through a pipeline. A collecting box can also be arranged between the dust collector 161 and the negative pressure device. A filter screen is arranged on the pipeline connected between the collecting box and the negative pressure device, so that the inhaled carbonized paint layer powder is collected by the collecting box.

[0050] It should be noted that the two ends of the first rotating shaft 21 are rotationally connected through bearings and bearing seats, and the bearing seats are fixed on the two sides of the upper end of the rack 1 frame through bolts. Obviously, the bearing seats can also be installed inside or outside the rack 1.

[0051] It should be noted that the second rotating shaft 31 is provided with a sleeve at one end, bearings are arranged at both ends in the sleeve, the second rotating shaft 31 is fixedly connected with the inner rings of the two bearings in the sleeve, and the sleeve is fixed on the mounting frame 11 or the rack 1. The sleeve can be fixed by direct welding or by a plate (one or a plurality of plates arranged in sequence in the vertical direction) fixed on the mounting frame 11 or the rack 1.

[0052] It should be noted that the second rotating shaft 31 is generally arranged vertically relative to the first rotating shaft 21.

[0053] Embodiment 2

[0054] In order to further ensure the paint removal effect, the following improvements are made.

[0055] As shown in Figure 1 , Figure 4 , a mounting plate 12 is also provided, which can slide up and down relative to the rack 1. The mounting plate 12 is connected to the connecting plate member at the bottom of the two slides through the slides on both sides and the tracks on both sides of the rack 1 (the side of the slide is provided with a guide wheel or a sliding block connected with the track guide groove). At least one linear drive device (cylinder, hydraulic cylinder, electric cylinder, etc.) is provided inside the rack 1 to drive the connecting plate member at the bottom of the two slides to move up and down, thereby driving the slides to move up and down, and further driving the mounting plate 12 to move up and down. Obviously, the above-mentioned mode is only one scheme for realizing the up-and-down movement of the mounting plate 12. Two linear drive devices can also be installed on the rack 1, and the output ends of the linear drive devices are fixedly connected to the two sides of the mounting plate 12. A rotary drive device 5 (motor, pneumatic motor, etc.) can also be used to realize the up-and-down movement of the mounting plate 12 by cooperating with a gear rack.

[0056] A blocking brush assembly 4 is vertically arranged in the direction of movement of the hub. The blocking brush assembly 4 includes a third rotating shaft 41 and a third disc brush 42. The upper end of the third rotating shaft 41 is rotatably installed on the mounting plate 12. At least one third disc brush 42 is fixedly arranged on the outer wall of the third rotating shaft 41. The rotation direction of the third rotating shaft 41 is consistent with the rotation direction of the second rotating shaft 31, which can ensure that the rotation direction of the third disc brush 42 is consistent with that of the second disc brush 32, further pushing the hub to rotate. In specific use, the mounting plate 12 moves downward, the blocking brush assembly 4 blocks the hub, and the hub rotates under the joint action of the second disc brush 32 and the third disc brush 42. Compared with embodiment 1, the rotation speed of the hub is increased, the third disc brush 42 is added, and thus the paint removal efficiency is improved, and the length of the entire rack 1 is greatly shortened, thereby reducing the demand of the rack 1 for the space of the factory building (in order to ensure the effect of side paint removal, the rack 1 needs to be arranged with a relatively long length).

[0057] As a further scheme, at least one blocking brush assembly 4 arranged on the same mounting plate 12 forms a group, and at least one group of blocking brush assemblies 4 is arranged in the direction of movement of the hub. After arranging multiple groups of blocking brush assemblies 4, multiple hubs can be simultaneously subjected to side paint removal without dead angle, and the processing efficiency is relatively high, but a corresponding automatic control device (for example, an infrared probe or a gravity sensor is used to detect the position of the hub, and then a linear drive device is triggered to drive the blocking brush assembly 4 to move up and down) needs to be used.

[0058] Obviously, when two blocking brush assemblies 4 are a group, the two blocking brushes can be symmetrically distributed in the moving direction of the wheel hub, and when more than three blocking brush assemblies 4 are a group, the plurality of blocking brush assemblies 4 can be arranged in an arc shape that fits the side surface of the wheel hub, so that each blocking brush assembly 4 can fully contact the side surface of the wheel hub.

[0059] As a further solution, a safety door 13 is also provided, which is arranged at the input end of the rack 1. Through the arrangement of the safety door 13, the number of wheels input into the rack 1 can be controlled. In addition, the safety door 13 can cooperate with the plurality of blocking brush assemblies 4 to prevent the plurality of wheel hubs from being too close to each other in the moving direction, thereby affecting the side surface paint removal effect.

[0060] The safety door 13 is installed in an up-down moving manner. When the number of wheel hubs entering the rack 1 reaches a predetermined number, the safety door 13 is closed. After the paint removal is completed, the safety door 13 is opened, and a predetermined number of wheel hubs (which matches the number of groups of blocking brush assemblies 4) are input into the rack 1 again.

[0061] As a further solution, a plurality of first disc brushes 22 are arranged at intervals on the same first rotating shaft 21, and the first disc brushes 22 on the two first rotating shafts 21 close to each other are arranged alternately. A plurality of second disc brushes 32 are arranged at intervals on the same second rotating shaft 31, and the second disc brushes 32 on the two second rotating shafts 31 on the same side and close to each other are arranged alternately. A plurality of third disc brushes 42 are arranged at intervals on the same third rotating shaft 41, and the third disc brushes 42 on the two third rotating shafts 41 in the same group and close to each other are arranged alternately.

[0062] The first disc brushes 22 are arranged in an alternating manner, which can increase the number of contact points between the first disc brushes 22 and the bottom surface of the wheel hub in the moving direction of the wheel hub, and can also increase the contact area between the first disc brushes 22 and the bottom surface of the wheel hub. Increasing the number of contact points can prevent the wheel hub from being stuck or jolted during transportation when the distance between two first disc brushes 22 is large. Increasing the contact area can obviously improve the paint removal speed on the bottom surface.

[0063] The second disc brushes 32 and the third disc brushes 42 are arranged in an alternating manner, which can increase the number of contact points between the second disc brushes 32 and the third disc brushes 42 and the side surface of the wheel hub in the rotating direction of the wheel hub, and can also increase the contact area between the second disc brushes 32 and the third disc brushes 42 and the side surface of the wheel hub. Increasing the number of contact points can ensure that the wheel hub is rotated. Increasing the contact area can obviously improve the paint removal effect on the side surface.

[0064] As Figure 2As shown, the relative positions between the plurality of first brushes 22, between the plurality of second brushes 32, and between the plurality of third brushes 42 are ensured by the spacer sleeves, which are sleeved on the outer walls of the first shaft 21, the second shaft 31, or the third shaft 41, and abut against the first brushes 22 on both sides, the second brushes 32 on both sides, and the third brushes 42 on both sides, respectively, thereby limiting the distance between two mutually approaching first brushes 22, two mutually approaching second brushes 32, and two mutually approaching third brushes 42.

[0065] As shown in FIG. 1, the first brushes 22, the second brushes 32, and the third brushes 42 are arranged in a staggered manner on the first shaft 21, the second shaft 31, and the third shaft 41, respectively. Figure 2 As shown, the limiting locking sleeves are fixed on the first shaft 21, the second shaft 31, and the third shaft 41 by means of the set screws, and the limiting locking sleeves on both sides press the two outermost first brushes 22 on the first shaft 21, the two outermost second brushes 32 on the second shaft 31, and the two outermost third brushes 42 on the third shaft 41.

[0066] As a further solution, as shown in FIG. 2, Figure 4 、 Figure 6 As shown, the same second shaft 31 includes at least one second brush 32 with a diameter of 200-240 mm and at least one second brush 32 with a diameter of 260-300 mm, and the same third shaft 41 includes at least one third brush 42 with a diameter of 200-240 mm and at least one third brush 42 with a diameter of 260-300 mm. The larger-diameter second brush 32 is arranged at the middle of the second shaft 31, and the larger-diameter third brush 42 is arranged at the middle of the third shaft 41, which can better fit the side of the hub.

[0067] Obviously, more than two second brushes 32 with different diameters can be arranged on the same second shaft 31, for example, a second brush 32 with a diameter of 300 mm is arranged at the middle, and second brushes 32 with diameters of 280 mm, 260 mm, 240 mm, 220 mm, and 200 mm are arranged in sequence on both sides. In this way, each second brush 32 can fully contact the side of the hub.

[0068] Obviously, more than two third brushes 42 with different diameters can be arranged on the same third shaft 41, for example, a third brush 42 with a diameter of 300 mm is arranged at the middle, and third brushes 42 with diameters of 290 mm, 280 mm, 270 mm, 260 mm, 240 mm, 230 mm, 220 mm, 210 mm, and 200 mm are arranged in sequence on both sides. In this way, each third brush 42 can fully contact the side of the hub.

[0069] It should be noted that the bristles of the first brush 22, the second brush 32 and the third brush 42 are circumferentially arranged on the outer wall thereof, the first brush 22 can also be a brush roller, the second brush 32 and the third brush 42 can be a special-shaped brush roller (the shape thereof is matched with the side surface of the hub), and the bristles can be made of plastic wire, nylon wire, sisal, abrasive wire, punched steel wire brush and the like.

[0070] As a further solution, the driving mode and transmission mode of the lower brush assembly 2, the side brush assembly 3 and the blocking brush assembly 4 are described in detail.

[0071] The rotating driving device 5 drives the first rotating shaft 21 to rotate through the transmission device 51, and the plurality of first rotating shafts 21 are synchronously rotated through the synchronous device 52; the rotating driving device 5 drives the second rotating shaft 31 to rotate through the transmission device 51, and the plurality of second rotating shafts 31 in the same group are synchronously rotated through the synchronous device 52; the rotating driving device 5 drives the third rotating shaft 41 to rotate through the transmission device 51, and the plurality of third rotating shafts 41 in the same group are synchronously rotated through the synchronous device 52.

[0072] The rotating driving device 5 is an electric motor or a pneumatic motor, the transmission device 51 is a gear set, a pulley and a toothed belt, a sprocket and a chain, etc., and the synchronous device 52 is a pulley and a toothed belt, a sprocket and a chain, etc.

[0073] In order to ensure that the plurality of first rotating shafts 21, the plurality of second rotating shafts 31 and the plurality of third rotating shafts 41 are synchronously rotated, as shown in Figs. Figure 5 , Figure 6 A sprocket set is arranged on the first rotating shaft 21, the second rotating shaft 31 and the third rotating shaft 41, the sprocket set adopts two sprockets, two chains are used to connect the two sprockets of the sprocket set with the sprockets on the adjacent two sides, and the synchronous rotation of the plurality of first rotating shafts 21, the plurality of second rotating shafts 31 and the plurality of third rotating shafts 41 is realized in this way.

[0074] It should be noted that, as shown in Fig. Figure 4 One end of the third rotating shaft 41 is externally provided with a sleeve, bearings are arranged at both ends in the sleeve, the third rotating shaft 41 is fixedly connected with the inner rings of the two bearings in the sleeve, and the sleeve is fixed on the mounting plate 12.
