[0025] In order to make the purpose, features and advantages of the utility model more obvious and easy to understand, the technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.
[0026] An embodiment of the utility model provides a pole ear dust removal device, including a blowing structure, a horizontal bearing structure and a suction structure; the blowing structure is used to generate a blowing airflow, through which the dust on the pole piece or the pole ear is blown away; the horizontal bearing structure makes the pole piece and the pole ear in a horizontal state for dust removal operation, which can avoid or reduce the probability of deformation of the pole piece and the pole ear; the suction structure is used to generate negative pressure to concentrate the removed dust to avoid dispersion into the surrounding environment.
[0027] The following is a detailed description of the various structures of the tab dust removal device provided by the embodiment of the utility model, as well as the positional relationship and connection relationship between the various structures, in conjunction with the accompanying drawings.
[0028] like Figures 1 to 4 As shown, the blowing structure 10 includes an air blowing port, which is used to blow out clean air, thereby forming an air blowing duct with a set path; dust on the pole ear 50 or the pole piece 40 is removed by the airflow generated by the blowing structure 10.
[0029] For example, in the embodiment of the utility model, the blowing structure 10 is a blowing air knife 11, and the blowing air knife 11 is arranged above the horizontal bearing structure 20; the blowing direction of the blowing air knife 11 has a set angle with the surface of the horizontal bearing structure 20.
[0030] For example, the position, angle and wind speed of the air blowing knife 11 can be adjusted. For example, the air blowing knife 11 also includes a slide rail 12, one end of which is connected to the bracket 60, and the air blowing knife 11 is slidably connected to the slide rail 12 through a slider 13. The position of the air blowing knife 11 can be adjusted by adjusting the slider 13 to move on the slide rail 12, or, for example, the air blowing knife 11 also includes an angle adjustment frame 14, and the air blowing knife 11 is connected to the slider 13 through the angle adjustment frame 14. By adjusting the position of the slider 13 on the slide rail 12, or adjusting the angle of the angle adjustment frame 14, the path of the air duct of the air blowing knife 11 can be adjusted.
[0031] Continue to refer Figures 1 to 4 As shown, the horizontal bearing structure 20 is used to bear the pole piece 40 and the pole ear 50. The horizontal bearing structure 20, the pole piece 40 and the pole ear 50 are arranged on the blowing air duct. The pole piece 40 and the pole ear 50 are placed in a horizontal state on the horizontal bearing structure 20. The pole piece 40 and the pole ear 50 are dusted by the blowing structure 10 above, which can avoid / reduce the probability of deformation of the pole ear 50 and the pole piece 40.
[0032] For example, the horizontal bearing structure 20 includes a conveying roller 21, and the top of the front end of the conveying roller 21 is used to roll and convey the pole piece 40 and the pole tab 50. The pole piece 40 and the pole tab 50 that have been processed have a set length. In order to realize the continuous conveying of the pole piece 40 and the pole tab 50, the horizontal bearing and conveying operation can be realized by the conveying roller 21. That is, the pole piece 40 and the pole tab 50 are input from other directions of the conveying roller 21, and after passing through the top of the conveying roller 21, they are conveyed to other positions, and dust removal operation is performed on them when passing through the top of the conveying roller 21.
[0033] When the pole piece 40 and the pole ear 50 are located at the top of the conveying roller 21, a small part of the pole piece 40 is in contact with the top of the conveying roller 21, and the pole ear 50 is higher than the conveying roller 21, and only the end may be in contact with the conveying roller 21 under the action of its own weight. Under this structural form, during the blowing operation, both sides of the pole piece 40 and the pole ear 50 can be blown to remove dust, thereby ensuring a sufficient dust removal effect.
[0034] For example, the conveying roller 21 includes a rotating shaft 22, one end of which is connected to the bracket 60; and the rotating shaft 22 and the slide rail 12 are arranged in parallel. The slide rail 12 located above the conveying roller 21 is connected to the blowing structure 10, and the blowing structure 10 blows water vapor obliquely downward to the conveying roller 21, and then, a suction structure 30 is arranged at the end of the conveying roller 21 to centrally process the dust.
[0035] Continue to refer Figures 1 to 4As shown, in the embodiment of the utility model, the suction structure 30 is arranged on the blowing air duct and is located downstream of the pole piece 40 and the pole ear 50. The suction structure 30 is used to suck the dust blown down from the pole piece 40 and the pole ear 50. By setting the suction structure 30, the dust on the pole piece 40 and the pole ear 50 can be centrally processed after being blown down, thereby avoiding / reducing the impact on the surrounding environment.
[0036] For example, the suction structure includes a dust suction chamber 31 and a negative pressure suction device (not shown in the figure); the dust suction chamber 31 includes a suction port 32 and a dust suction port 33, the suction port 32 is connected to the negative pressure suction device, the dust suction port 33 is located downstream of the pole piece 40 and the pole ear 50, and the negative pressure suction device is used to generate a negative pressure environment in the dust suction chamber 31. When in use, the negative pressure suction device is operated to generate a negative pressure environment in the dust suction chamber 31, and the negative pressure environment generates a suction airflow for the dust suction port 33, thereby sucking the dust at this position into the dust suction chamber 31.
[0037] For example, the front end of the conveying roller 21 is inserted into the dust suction cavity 31, and the pole ear 50 and part of the pole piece 40 are located in the dust suction cavity 31; the dust suction cavity 31 is provided with a through-port 34 and a through-port 35 on the side where the dust suction port 33 is located, and the pole piece 40 and the pole ear 50 enter the dust suction cavity 31 through the through-port 34 and exit through the through-port 35.
[0038] Placing part of the pole piece 40 and the pole ear 50 in the dust suction chamber 31 can ensure that the pole piece 40 and the pole ear 50 are placed in a negative pressure environment, thereby facilitating sufficient suction of dust.
[0039] When the pole ear dust removal device is in dust removal operation, the blowing structure 10 and the suction structure 30 are started, and at the same time, the pole piece 40 and the pole ear 50 are dragged to move by a pulling mechanism or a winding mechanism outside the device, and the pole piece 40 and the pole ear 50 move on the conveying roller 21, causing the conveying roller 21 to rotate, and as the pole ear 50 and the pole piece 40 pass through the blowing structure 10, the dust thereon is blown off, and the dust is collected centrally through the suction structure 30.
[0040] The pole ear dust removal device provided by the embodiment of the utility model, when in use, the pole piece 40 and the pole ear 50 are on the horizontal bearing structure 20, and the dust on the pole ear 50 or the pole piece 40 is blown off by the blowing structure 10, and the blown off dust is centrally sucked by the suction structure 30. In the technical solution of the utility model, the pole piece 40 and the pole ear 50 are dusted in a horizontal state, which can avoid / reduce the probability of the pole ear 50 being bent, and the blown off dust is centrally processed to avoid dust leakage and pollution.
