Description

Technical Field

[0001] The utility model relates to the technical field of emery cloth production, in particular to an air suction roller device for emery cloth production. Background Art

[0002] During the production process of abrasive cloth, the glue surface or sand surface after glue coating cannot transmit power by rolling, and can only generate force on one side to make the cloth base enter the drying room. At present, there are two main ways to transmit power to abrasive cloth. One is to use a negative pressure suction roller to transmit power, and the other is to use a suction plate to transmit power. The principle of using a negative pressure suction roller to transmit power is to drill rows of small holes on the surface of the suction roller, and a suction chamber is installed on the side of the roller, and then a pipeline negative pressure fan is introduced. When the row of holes reaches the position of the suction chamber, negative pressure will be generated, and the cloth base will be sucked when passing through its surface. In addition, the suction roller will rotate with power, thus completing the effect of conveying the cloth base forward. According to actual production needs, there will be several groups of suction rollers on each production line.

[0003] In actual use, the flying scraps on the surface of the cloth base and the abrasives after sand planting will be sucked away with the negative pressure air. The flying scraps and abrasives can easily damage the negative pressure fan, especially the abrasive, which has a hard texture and causes greater damage to the negative pressure fan, requiring frequent maintenance of the fan.

[0024] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0025] The suction roller device for producing abrasive cloth in this embodiment is achieved by the cooperation of the suction roller, the negative pressure box, the air filter and the negative pressure fan, thereby increasing the service life of the negative pressure fan while ensuring the normal operation of the suction roller.

[0026] like Figure 1 - Figure 6 As shown, the suction roller 2 device for producing abrasive cloth includes a frame 1, a suction roller 2, a negative pressure box 3, an air filter 4 and a negative pressure fan 5. The suction roller 2 is rotatably arranged on the frame 1, a suction hole 21 is arranged on the outer wall of the suction roller 2, and an air guide hole 22 is arranged on the end face of the suction roller 2. The negative pressure box 3 abuts against the end face of the suction roller 2, the negative pressure box 3 is hollow, and an air inlet hole 34 corresponding to the air guide hole 22 is arranged on the side wall of the negative pressure box 3. The negative pressure box 3 is connected to the air filter 4 through a pipeline, and the air filter 4 is connected to the negative pressure fan 5.

[0027] In actual use, air enters through the suction hole 21 on the outer wall of the suction roller 2, then enters the negative pressure box 3 through the air guide hole 22, and then enters the negative pressure fan 5 through the air filter 4. Through the operation of the negative pressure fan 5, negative pressure is formed in the suction roller 2. Since the air filter 4 is provided, the flying flowers, abrasives, etc. in the sandpaper will be blocked by the air filter 4 and will not enter the negative pressure fan 5, thereby improving the service life of the negative pressure fan 5 and avoiding frequent maintenance.

[0028] like Figure 1 , Figure 2 and Figure 3As shown, an abutment ring 23 is provided on the end face of the suction roller 2, and an air guide hole 22 is arranged on the abutment ring 23. At the same time, a plurality of air guide holes 22 are provided, and each air guide hole 22 is arranged in an arc shape, that is, the air guide holes 22 are provided on half of the area on the abutment ring 23, and the air guide holes 22 are not provided on the other half of the area.

[0029] At the same time, the negative pressure box 3 is installed on the frame 1 through a mounting piece, and a plurality of air inlet holes 34 are provided. Each air inlet hole 34 is also arranged in an arc shape, corresponding to the position of the air guide hole 22.

[0030] In actual use, abrasives, flying flowers, etc. are filtered through the air filter 4, which may easily cause the air filter 4 to be blocked for a long time without being easy to be discovered, thereby affecting the negative pressure generation effect. In some embodiments, an abrasive baffle 6 is provided in the negative pressure box 3 to preliminarily collect the abrasives, reducing the amount of abrasives entering the air filter 4 through the pipeline, thereby ensuring the negative pressure generation effect.

[0031] Specifically, Figure 5 As shown, the abrasive baffle 6 is arranged to be inclined downward, the upper end of the abrasive baffle 6 is connected to the first inner wall 31 of the negative pressure box 3, and the lower end is spaced apart from the second inner wall 32 of the negative pressure box 3. An air outlet 33 is arranged on the first inner wall 31 of the negative pressure box 3, and the air outlet 33 is connected to the air filter 4 through a pipeline, wherein the upper end of the abrasive baffle 6 is located above the air outlet 33. After the abrasive and flying flowers enter the negative pressure box 3, part of the abrasive falls along the abrasive baffle 6 due to the action of gravity. Due to the obstruction of the abrasive baffle 6, the abrasive cannot be directly output through the air outlet 33, so that part of the abrasive can fall without entering the air filter 4 through the air outlet 33, so as to improve the service life of the air filter 4 and reduce the maintenance of the air filter 4.

[0032] like Figure 4 and Figure 5 As shown, a receiving bin 7 is provided at the lower end of the negative pressure box 3. The receiving bin 7 is cone-shaped to facilitate the falling of the abrasive. At the same time, a slag discharge hole is provided at the lower end of the receiving bin 7. An end cover 8 is threadedly connected to the slag discharge port so that the abrasive can be discharged.

[0033] like Figure 6 As shown, the air filter 4 includes an upper shell 41, a lower shell 42 and a filter element. One side of the upper shell 41 is connected to the lower shell 42 through a hinge 43, and the other side is connected to the lower shell 42 through a lock 44. The filter element is arranged between the upper shell 41 and the lower shell 42, so as to facilitate the replacement of the filter element.

[0034] Obviously, the described embodiments are only a part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field belong to the protection scope of the utility model.
