[0027] The following further elaborates on the present utility model with reference to the attached drawings.

[0028] Embodiment:

[0029] Refer to Figure 1 - Figure 7 A dust removal device for a roller - through shot - blasting cleaning machine disclosed by the present utility model includes a shot - blasting machine 1. A roller track 2 for conveying workpieces runs horizontally through the bottom of the shot - blasting machine 1. A support frame 3 is fixedly connected to the input end of the roller track 2. Two cleaning tables 4 are arranged inside the support frame 3, and the two cleaning tables 4 are symmetrically arranged;

[0030] A chute 5 for the sliding of the cleaning table 4 is provided on the inner side wall of the support frame 3. The cleaning table 4 located below is fixedly connected to the support frame 3, and the cleaning table 4 located above is slidably arranged in the chute 5;

[0031] The cleaning table 4 includes a mounting plate 41, conveying rollers 42, cleaning rollers 43, auxiliary rollers 44 and cleaning felts 45. An installation groove 6 is formed on one side of the mounting plate 41 close to the workpiece. A conveying roller 42 is rotatably connected to one side of the installation groove 6 close to the input end of the roller path 2. An auxiliary roller 44 is rotatably connected to the side of the installation groove 6 away from the conveying roller 42. Two cleaning rollers 43 are symmetrically arranged between the conveying roller 42 and the auxiliary roller 44. The outer circumferences of the two cleaning rollers 43 are connected by a conveyor belt. A layer of cleaning felt 45 is laid on the outer side of the conveyor belt;

[0032] A dust removal assembly 7 for cleaning the cleaning felt 45 is arranged in the support frame 3. The conveying roller 42 is connected to one of the cleaning rollers 43 close to the conveying roller 42 through a driving assembly 8. The driving assemblies 8 of the two cleaning tables 4 are arranged in a staggered manner.

[0033] In this embodiment, during the storage and transportation of workpieces such as steel plates and sheet metal parts, dust will inevitably accumulate on their surfaces. If there is dust, oil stains or other impurities attached to the surface of the workpiece, these substances may absorb part of the energy of the projected shot, affecting the impact effect of the shot on the workpiece surface, thereby reducing the quality and efficiency of shot blasting treatment.

[0034] Therefore, observing Figure 1 it can be found that a support frame 3 is arranged at the input end of the roller path 2. Then observing Figure 2 it can be found that two cleaning tables 4 are symmetrically arranged in the support frame 3. When the workpiece enters the support frame 3 through the roller path 2, the front and back sides of the workpiece will be cleaned by the two cleaning tables 4, and the dust and pollutants on the workpiece surface can be removed, so that the workpiece remains clean when it enters the shot blasting machine 1 through the roller path 2, and when the steel shot of the shot blasting machine impacts the workpiece surface, the energy of the shot will not be absorbed by impurities such as dust or oil stains, effectively ensuring the surface cleaning effect of the workpiece.

[0035] And observing Figure 2 it can be found that the cleaning table 4 located below is fixedly connected to the support frame 3, and the cleaning table 4 located above is slidably arranged in a chute 5 formed in the support frame 3, so that the cleaning table 4 located above presses the workpiece under the action of gravity, so that there is sufficient friction between the front and back sides of the workpiece and the two cleaning tables 4, thereby ensuring the dust removal effect of the workpiece. The setting of the chute 5 can make the cleaning table 4 located above automatically slide up when being pressed by a thicker workpiece, so that the cleaning table 4 can adapt to the thickness of the workpiece, thereby improving the practicability of the dust removal device.

[0036] Since when the cleaning table 4 above presses the workpiece, the workpiece will be compressed and the friction will increase, resulting in the traction force applied by the roller path 2 to the workpiece being unable to push the workpiece forward, affecting the conveying of the workpiece. Therefore, observing Figure 2 and Figure 6It can be found that an installation groove 6 is formed in the installation plate 41 of the cleaning table 4, and a conveying roller 42 is rotatably connected to one side of the installation groove 6 close to the input end of the roller path 2. The rotation of the conveying roller 42 can provide an additional traction force for the workpiece to ensure the conveying efficiency of the workpiece. At the same time, two cleaning rollers 43 are arranged on one side of the conveying roller 42, and the two cleaning rollers 43 are connected by a conveyor belt. A layer of cleaning felt 45 is laid on the outer side of the conveyor belt. At the same time, one of the cleaning rollers 43 close to the conveying roller 42 is connected to the conveying roller 42 through a driving assembly 8. When the conveying roller 42 pushes the workpiece forward, it can drive the cleaning felt 45 to clean the surface of the workpiece, which can further ensure the cleaning effect of the workpiece surface.

[0037] Since the cleaning table 4 above floats according to the thickness of the workpiece, in order to prevent the two driving assemblies 8 from contacting and interfering with each other during operation, the two driving assemblies 8 are arranged in a staggered manner as Figure 4 shown, which can further ensure the operating stability of the driving assembly 8.

[0038] When the cleaning felt 45 cleans the dust, it will adsorb the dust particles on the surface of the cleaning felt 45. As the number of times of cleaning the workpiece increases, the amount of dust that the cleaning felt 45 can adsorb will gradually decrease, affecting the cleaning effect of the cleaning felt 45. Therefore, observing Figure 1 and Figure 3 it can be found that a dust removal assembly 7 for cleaning the cleaning felt 45 is arranged in the support frame 3, which can be used to clean the dust on the surface of the cleaning felt 45, ensure the use stability of the cleaning felt 45, enable the cleaning felt 45 to continuously perform dust removal operations on the workpiece for a long time, and further ensure the shot blasting and cleaning efficiency of the workpiece.

[0039] By rotatably connecting an auxiliary roller 44 to the side of the installation groove 6 away from the conveying roller 42, it can support the workpiece when the workpiece is pushed out of the support frame 3 after being cleaned, so that the workpiece can be smoothly conveyed out of the support frame 3, which can further ensure the conveying efficiency of the workpiece.

[0040] In a further preferred embodiment of the present utility model, as Figure 3 and Figure 4 shown, the driving assembly 8 includes a motor 81, a main gear 82 and a sub-gear 83. The motor 81 is fixedly connected to the outer side wall of the installation plate 41. The output shaft of the motor 81 extends into the installation plate 41 and is fixedly connected to the main gear 82. A sub-gear 83 is meshed with one side of the main gear 82. The main gear 82 and the sub-gear 83 are respectively fixedly connected to the ends of the conveying roller 42 and the cleaning roller 43.

[0041] In this embodiment, by arranging the motor 81, the main gear 82 and the auxiliary gear 83 can be driven to rotate, so that the cleaning roller 43 and the conveying roller 42 rotate in opposite directions. When the conveying roller 42 conveys the workpiece forward, the rotation direction of the cleaning felt 45 is opposite to the advancing direction of the workpiece, so that the cleaning felt 45 can better contact the surface of the workpiece, and the dust cleaning effect on the surface of the workpiece is better.

[0042] In a further preferred embodiment of the present utility model, as Figure 3 , Figure 6 and Figure 7 shown, the dust removal assembly 7 includes a vacuum cleaner 71, a corrugated pipe 72 and a suction head 73. The dust collector is installed outside the support frame 3. The suction head 73 is fixedly connected in the installation groove 6. The suction head 73 is connected to the vacuum cleaner 71 through the corrugated pipe 72, so that the suction head 73 is used to suck away the dust on the surface of the cleaning felt 45;

[0043] The suction port end of the suction head 73 is evenly distributed with bristles 9, and the side of the bristles 9 away from the suction head 73 contacts the outer surface of the cleaning felt 45.

[0044] In this embodiment, by arranging the vacuum cleaner 71, negative pressure can be generated in the corrugated pipe 72, so that suction force is generated at the suction port of the suction head 73, and the dust on the surface of the cleaning felt 45 is sucked away by the suction head 73, which is used to clean the cleaning felt 45 and extend the service life of the cleaning felt 45.

[0045] Since the cleaning felt 45 is formed by fiber bonding, the dust adsorbed in the miscellaneous fibers on its surface cannot be sucked away by suction, which affects the cleaning effect on the cleaning felt 45. Therefore, observing Figure 6 and Figure 7 it can be found that the suction port end of the suction head 73 is evenly distributed with bristles 9, and the end of the bristles 9 contacts the surface of the cleaning felt 45. When the cleaning felt 45 moves, the bristles 9 can be toggled, so that the bristles 9 brush off the dust in the fibers on the surface of the cleaning felt 45, which can further improve the cleaning effect on the cleaning felt 45, and thus further extend the service life of the cleaning felt 45.

[0046] In a further preferred embodiment of the present utility model, as Figure 1 , 4 and Figure 5 shown, the side wall of the sliding groove 5 is provided with an avoidance groove 10 for avoiding the motor 81 and the corrugated pipe 72, and the avoidance groove 10 penetrates through the support frame 3.

[0047] In this embodiment, since the cleaning table 4 above will float automatically according to the thickness of the workpiece, the motor 81 and the corrugated pipe 72 connected thereto will also move up and down. Therefore, in order to prevent the motor 81 and the corrugated pipe 72 from being blocked by the support frame 3 and affecting the floating of the cleaning table 4, as shown in Figure 5 the avoidance grooves 10 for avoiding the motor 81 and the corrugated pipe 72 are provided in the chute 5, and the avoidance grooves 10 penetrate through the support frame 3, which can be used to ensure the effect that the cleaning table 4 automatically adjusts its position according to the thickness of the workpiece.

[0048] In a further preferred embodiment of the present utility model, as shown in Figure 2 the top of the outer peripheral wall of the conveying roller 42 and the auxiliary roller 44 is flush with the conveying plane of the roller path 2, and the cleaning plane of the cleaning felt 45 is higher than the conveying plane of the roller path 2.

[0049] In this embodiment, by making the top of the outer peripheral wall of the conveying roller 42 and the auxiliary roller 44 flush with the conveying plane of the roller path 2, the workpiece can be kept stable when passing through the support frame 3, and the conveying efficiency of the workpiece can be improved.

[0050] Since both the conveyor belt and the cleaning felt 45 are flexible objects, they will be deformed by extrusion when the workpiece passes through the support frame 3. Therefore, in order to ensure the contact pressure between the cleaning felt 45 and the surface of the workpiece, by making the cleaning plane of the cleaning felt 45 higher than the conveying plane of the roller path 2, the workpiece can squeeze the cleaning felt 45 when entering the support frame 3, causing the cleaning felt 45 to deform and increasing the contact pressure between the cleaning felt 45 and the surface of the workpiece, thereby improving the cleaning effect of the cleaning felt 45 on the workpiece.

[0051] The embodiments of this specific implementation manner are all preferred embodiments of the present utility model, and do not limit the protection scope of the present utility model accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present utility model shall be covered within the protection scope of the present utility model.
