Description

Technical Field

[0001] The utility model relates to the field of mechanical equipment, in particular to a pulley protective cover with an anti-corrosion function. Background Art

[0002] Waste paper can be recycled as raw material to become base paper, such as kraft paper, which has important positive significance for the papermaking industry. It can achieve effective utilization of resources, environmental protection, energy conservation and sustainable economic development.

[0003] In the prior art, when recycling waste paper, foreign matters such as metals in the waste paper are screened out through a sorting device, and then the waste paper is conveyed to the recycling equipment through a conveyor belt through a pulley, and then the waste paper is subjected to subsequent processing steps;

[0035] It also includes an air supply assembly, to which all the fixing frames 2 on the right side of the shielding cover 3 are fixedly connected; all the fixing frames 2 on the left side of the shielding cover 3 are fixedly connected to another air supply assembly; the air supply assembly on the right side of the shielding cover 3 is composed of a connecting plate 201, a pump 202, a conduit 203 and a blocking piece 204; the fixing frames 2 on the right side of the shielding cover 3 are fixedly connected to the connecting plate 201; the connecting plate 201 is fixedly connected to the pump 202; the pump 202 is fixedly connected to the conduit 203; the conduit 203 is fixedly connected to the blocking piece 204, and the conduit 203 passes through the blocking piece 204, and the blocking piece 204 is rotatably connected to the transmission bar 103 at the corresponding position.

[0036] The fixed connecting piece 301, the rotating transmission ring 302, the spherical rotor 303 and the hollow roller 304 are all hollow; the fixed connecting piece 301 is connected to the transmission bar 103; the spherical rotor 303 has a through hole, and the through hole of the spherical rotor 303 is connected to the local cavity formed by the fixed connecting piece 301 and the rotating transmission ring 302; the hollow roller 304 is connected to the spherical rotor 303, and the hollow roller 304 has a plurality of air holes 304a.

[0037] Each hollow rotating roller 304 is fixedly connected to two cutters 305 , and the length of the cutters 305 is shorter than the length of the bristles 305 a when viewed from top to bottom.

[0038] It also includes a pushing component, all the fixing frames 2 on the right side of the shielding cover 3 are fixedly connected to the pushing component; all the fixing frames 2 on the left side of the shielding cover 3 are fixedly connected to another pushing component; the pushing component on the right side of the shielding cover 3 is composed of an electric push rod 401 and a pushing bar 402; all the fixing frames 2 on the right side of the shielding cover 3 are respectively fixedly connected to an electric push rod 401, and all the electric push rods 401 are electrically connected to the pressure sensor of the shielding cover 3, and all the electric push rods 401 are fixedly connected to a pushing bar 402, and the pushing bar 402 runs through the vertical part of the shielding cover 3.

[0039] Before using the device, the connecting strip 1 is installed on the conveying wheel 1a, and a waste liquid bucket is placed under the rear of each drainage strip 5. Then the conveying wheel 1a is started to work, so that the shielding cover 3 and the blocking net 4 can shield the waste paper material splashed from the conveying wheel 1a, and the residual liquid on the waste paper material can flow into the drainage strip 5 from the gap of the blocking net 4, so as to better ensure the overall cleanliness of the conveying wheel 1a;

[0040] However, since the splashed waste paper will inevitably carry sticky and corrosive liquid, the shielding cover 3 is very easy to adhere to the waste paper. The waste paper will accumulate and adhere to form lumps over a long period of time, which will cause the transmission channel composed of the shielding cover 3, the blocking net 4 and the conveying wheel 1a to be blocked, and the liquid adhered to the shielding cover 3 is corrosive and will greatly reduce the service life of the shielding cover 3. Therefore, while the shielding cover 3 is working normally, the DD motor 101 starts to work and drives the connected rotating shaft 102 to rotate. The rotation of the rotating shaft 102 drives the transmission bar 103 to start rotating around the shielding cover 3. The rotation of the transmission bar 103 drives the connected scraper bar 104 to rotate close to the shielding cover 3. The scraper bar 104 can scrape off the waste paper and residual liquid adhered to the shielding cover 3 during the rotation process, so that the shielding cover 3 will not form lumps on the surface after long-term work, so that it will not hinder the normal transmission work of the conveying wheel 1a, and relatively keep the surface of the shielding cover 3 clean, thereby extending the service life of the shielding cover 3.

[0041] Furthermore, after long-term use, the surface of the blocking net 4 will inevitably be clogged with fine waste paper materials. According to the foregoing, due to the residual liquid in the waste paper materials, the waste paper materials clogging the surface of the blocking net 4 will be more difficult to clean. Therefore, when the transmission bar 103 rotates around the shielding cover 3, it will drive the connected fixed connecting piece 301 to rotate together, and the fixed connecting piece 301 will drive the connected rotating transmission ring 302 to rotate around the shielding cover 3. When the rotating transmission ring 302 rotates around the shielding cover 3, since the rotating transmission ring 302 contacts the vertical part of the shielding cover 3, Under the action of rotational friction, the rotating transmission ring 302 starts to rotate, and the rotating transmission ring 302 drives the connected spherical rotating head 303 to rotate and rotate, and the spherical rotating head 303 drives the connected hollow rotating roller 304 to rotate and rotate. In this process, the bristles 305a provided on the hollow rotating roller 304 also rotate and rotate. At this time, the bristles 305a will rotate and clean the blocking net 4 in this process, so that the blocking net 4 can be cleaned at all times when the conveying wheel 1a is working, and the blocking net 4 can work normally to discharge the residual liquid on the waste paper material;

[0042] Furthermore, when the waste paper is being transported on the conveying wheel 1a, if the natural flow of liquid alone is insufficient to remove most of the residual liquid on the waste paper, it will take a longer time to process the waste paper when it is subsequently recycled, and the recycling efficiency will be reduced. Therefore, while the transmission bar 103 drives the hollow roller 304 to work, the pump 202 starts to work, and introduces air into the cavity formed by the transmission bar 103 and the blocking piece 204 through the conduit 203. The air in the cavity formed by the transmission bar 103 and the blocking piece 204 will flow into the hollow roller 304 through the fixed connecting piece 301, the rotating transmission ring 302 and the spherical rotor 303. At this time, the air in the hollow roller 304 will be ejected from the air hole 304a, and the air ejected from the air hole 304a will be ejected toward the waste paper, so that the residual liquid on the waste paper is blown by the air. At this time, the residual liquid on the waste paper can be further removed, shortening the time required for the subsequent recycling of the waste paper.

[0043] Furthermore, since there will inevitably be some relatively large waste papers such as cardboard boxes in the waste paper materials, although they will be flattened before being put into the conveying wheel 1a, in the actual transmission process, due to the angle when being put into the conveying wheel 1a and the problem of residual sticky substances on the conveying wheel 1a, the large waste papers will easily block the transmission channel formed by the conveying wheel 1a, the shielding cover 3 and the blocking net 4 during transmission, which leads to the need to stop the machine frequently to clean the transmission channel, which greatly reduces the transmission efficiency of the conveying wheel 1a. Therefore, when the conveying wheel 1a is transmitting, when the transmission channel is blocked, it will squeeze the shielding cover 3. At this time, the pressure sensor on the shielding cover 3 will send a signal to control the electric push rod 401 to push the push bar 402 to move toward the middle of the shielding cover 3. At this time, the push bar 402 will squeeze the lower part of the spherical rotor 303 at the corresponding position during the movement, and the spherical rotor 303 drives the connected hollow roller 304 and the cutter 305 to tilt toward the middle of the shielding cover 3 to form a Figure 7 The hollow rollers 304 facing each other are staggered, and similarly, the cutters 305 facing each other are staggered. Thus, when the cutters 305 rotate around the shielding cover 3, they can cut and tear the large waste paper in an offset manner, so that the large waste paper is torn into pieces. Thus, the transmission channel can be unblocked without stopping the machine, thereby ensuring the normal transmission work and greatly improving the transmission efficiency.

[0044] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention.
