Referring to fig. 1 and 2, in some embodiments of the present invention, a brush finishing apparatus of a brush roll includes a frame 100, a swing arm 200, a finishing brush 300, and a driving device 400. One end of the swing arm 200 is hinged with the bracket 100; the whole brush piece 300 is connected with the other end of the swing arm 200, and the whole brush piece 300 is parallel to the brush roll; the driving device 400 is disposed on the bracket 100, and an output end of the driving device 400 is connected to the swing arm 200 to drive the whole brush member 300 to abut against or be away from the brush roll, and the whole brush member 300 can abut against the brush roll for brushing the brush roll.

Specifically, the whole brush 300 is connected to the swing arm 200 disposed on the bracket 100, the whole brush 300 is parallel to the brush roll, and during the production operation, the swing arm 200 drives the whole brush 300 to move under the driving of the driving device 400, so that the whole brush 300 can be abutted to the brush roll, thereby trimming the brush roll. The real-time online finishing avoids the need of disassembling the brush roll during the whole brushing process, improves the production efficiency and reduces the cost.

In some embodiments of the present invention, the swing arm 200 is connected to the support 100 through a rotating shaft 500 rotatably disposed on the support 100.

Specifically, the swing arm 200 is connected to the bracket 100 through the rotating shaft 500, and when the rotating shaft 500 rotates, the bracket 100 installed on the rotating shaft 500 swings to drive the entire brush member 300 to abut against or be away from the brush roller, so as to complete brushing of the brush roller.

Referring to fig. 3 and 4, in some embodiments of the present invention, one end of the rotating shaft 500 is connected to the output end of the driving device 400 through the swing connection plate 510, and the other end of the rotating shaft 500 is connected to the bracket 100 through a bearing.

Specifically, the output end of the driving device 400 is connected to one end of the rotating shaft 500 through the swing connecting plate 510 to drive the rotating shaft 500 to swing along with the swing connecting plate 510, and the purpose of using the swing connecting plate 510 is to rotate the rotating shaft 500 in a range of 0 ° to 90 °, limit the rotation amplitude of the rotating shaft 500, and save the process time. The other end of the rotating shaft 500 is connected to the bracket 100 through a bearing, and the connection between the bearing and the swing connecting plate 510 is also connected through a bearing.

In particular, in some embodiments of the present invention, the bearings are deep groove ball bearings, which are selected to be able to withstand not only radial but also axial forces. The deep groove ball bearing has small friction coefficient and high limit rotating speed. The deep groove ball bearing is used, so that the frequency of replacing and maintaining the bearing can be reduced, the cost is saved, and the efficiency is improved.

In some embodiments of the present invention, the driving unit 400 is a cylinder assembly, and the output end of the driving unit 400 is hinged to the swing link plate 510.

Specifically, in some embodiments of the present invention, the driving device 400 is an air cylinder assembly, the output end of the driving device 400 is hinged to the swing connecting plate 510, and the swing angle of the swing connecting plate 510 is precisely controlled by pressure adjustment, so as to avoid the situation that the entire brush 300 collides with the brush roll due to the large rotation amplitude of the rotating shaft 500, which causes damage to the entire brush 300 and a large degree of brushing of the brush roll, and reduces the use efficiency.

Referring to fig. 3, in some embodiments of the present invention, the number of the swing arms 200 is two, one end of the entire brush 300 is connected to one end of the rotation shaft 500 through one swing arm 200, and the other end of the entire brush 300 is connected to the other end of the rotation shaft 500 through the other swing arm 200.

Specifically, the number of the swing arms 200 is two, so that when the whole brush member 300 abuts against the brush roll, the pressure applied to the brush roll by the whole brush member 300 is even, and the problem that the whole brush quality of the brush roll is low due to unbalanced stress caused by the use of the swing arms 200 is avoided.

Referring to fig. 2, 3 and 4, in some embodiments of the present invention, the swing arm 200 is provided with a joint block 210, and the joint block 210 is connected to the entire brush 300.

Specifically, in the process that the swing arm 200 swings to drive the whole brush piece 300 to abut against or be away from the brush roll, due to abutting collision between the whole brush piece 300 and the brush roll, abrasion occurs between the whole brush piece 300 and the swing arm 200 due to vibration, when the abrasion is large, connection between the whole brush piece 300 and the swing arm 200 is unstable, the whole brush is shaken, and when the whole brush piece 300 brushes the brush roll, uneven stress causes unevenness of the whole brush. Use the switching piece 210 to be connected swing arm 200 and whole brush 300, when switching piece 210 played the cushioning effect, when the adapter took place the wearing and tearing back, only need with switching piece 210 change can, avoid changing spare parts such as swing arm 200. The swing arm 200 is complicated to replace, and the adapter block 210 is simple to connect and convenient to detach. The use of the transfer block 210 may save costs.

In some embodiments of the present invention, the cross-section of the whole brush 300 is square, two adjacent surfaces of the whole brush 300 are provided with through holes, the whole brush 300 is further provided with a connecting member 310, and the connecting member 310 passes through one of the through holes to be fixedly connected with the transfer block 210.

Referring to fig. 4, the overall brush member 300 is illustrated as having a square cross-section, i.e., the overall brush member 300 has four outer surfaces, all of which may be used in an overall brush roll. Two connected surfaces at two ends of the whole brush 300 are provided with through holes, the whole brush 300 is provided with a connecting piece 310, and the connecting piece 310 penetrates through any through hole to be connected with the switching block 210 in a solid manner.

The connecting member 310 is a bolt, and since the outer surface of the entire brush member 300 is worn by a long time of the entire brush, the entire brush member 300 has a poor effect of the entire brush of the brush roll after the wear, and the entire brush member 300 needs to be replaced at this time. And four outer surfaces of the entire brush member 300 used in the present invention can perform the entire brushing of the brush roll, and when one surface of the entire brush member 300 is worn, the connecting member 310 is unscrewed, and the other outer surface of the entire brush member 300 is aligned with the brush roll to perform the entire brushing, thereby preventing the entire brush member 300 from being frequently replaced and saving the cost.

In some embodiments of the present invention, the entire brush member 300 is a hollow structure.

Specifically, since the whole brush 300 needs to swing to lean against or be far away from the brush roll, in order to avoid the excessive impact force of the whole brush 300 on the brush roll, the middle of the whole brush 300 is hollowed and is set to be a hollow structure, so that on one hand, the material cost can be saved, on the other hand, the quality of the whole brush 300 is reduced, the bearing pressure of the swing arm 200 and the rotating shaft 500 is reduced, the energy consumption is reduced, and the influence on the stability of the device caused by the excessive vibration in the working process can be prevented.

The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.

The present invention is not limited to the above-described embodiments, and those skilled in the art can make equivalent modifications or substitutions without departing from the spirit of the present invention, and such equivalent modifications or substitutions are included in the scope defined by the claims of the present application.
