[0027] Example 1

[0028] The present application proposes a dust-sticking device for cleaning a core plate, a dust-sticking device for cleaning a core plate, comprising a transmission component, a dust-sticking roller is mounted on the transmission component, the dust-sticking roller is connected to a first rotating driving member, the first rotating driving member drives the dust-sticking roller to rotate around its axis, and a transmission channel for the core plate to pass through is formed between the dust-sticking roller and the transmission component; when the core plate passes through the transmission channel, the dust-sticking roller abuts against the upper surface of the core plate, the transmission component abuts against the lower surface of the core plate, and the dust-sticking roller and the transmission component have the same transmission direction for the core plate.

[0029] In the present application, the sticky roller and the core plate are in a rotationally connected relationship, that is, the sticky roller and the transmission assembly transmit the core plate together from the top and bottom of the core plate respectively. At the same time, due to the rotational contact between the sticky roller and the core plate, it can ensure that the upper surface of the core plate is fully contacted with the sticky roller, and ensure that the outer peripheral side of the sticky roller is evenly contacted with the core plate, thereby improving the cleaning efficiency of the upper surface of the core plate.

[0030] Example 2

[0031] See also Figure 1-Figure 3The present application proposes a dust-sticking device for cleaning a core plate, comprising a transmission component, a dust-sticking roller mounted on the transmission component, the dust-sticking roller being connected to a first rotating driving member, the first rotating driving member driving the dust-sticking roller to rotate around its axis, and a transmission channel for the core plate to pass through is formed between the dust-sticking roller and the transmission component; when the core plate passes through the transmission channel, the dust-sticking roller abuts against the upper surface of the core plate, the transmission component abuts against the lower surface of the core plate, and the dust-sticking roller and the transmission component have the same transmission direction for the core plate.

[0032] The two ends of the dust sticking roller of the present application are located in the sliding groove 16, and the extending direction of the sliding groove 16 is perpendicular to the transmission direction of the transmission component. Specifically, the sliding groove 16 can be a U-shaped groove, and the opening of the U-shaped groove faces away from the transmission component.

[0033] In the present application, the sliding groove 16 is a U-shaped groove with an opening facing away from the transmission component, and the two ends of the sticky roller are located in the U-shaped groove. The shape design of the U-shaped groove allows the two ends of the sticky roller to be placed more firmly in the sliding groove 16; the inner wall width of the sliding groove 16 is greater than the radial dimension of the sticky roller, and when the sticky roller is located at the bottom of the sliding groove 16, the two ends of the sticky roller are located at the bottom of the sliding groove 16, and the sliding groove 16 extends in a direction away from the transmission component. When the transmission component is a horizontal transmission component, the sliding groove 16 extends vertically, and the opening of the U-shaped groove is set upward.

[0034] When the core plate passes through the transmission channel, if the core plate is thin, the sticky roller will slide down to the bottom of the sliding groove 16 under the action of gravity, ensuring that the bottom of the sticky roller abuts against the sliding groove 16, so as to remove impurities on the upper surface of the core plate. When the core plate is thicker, since the sticky roller can slide up and down in the sliding groove 16, under the lifting force of the core plate, the two ends of the sticky roller will rise along the sliding groove 16 during the rotation process, ensuring that the sticky roller abuts against the upper surface of the core plate.

[0035] The sliding groove 16 provided in the present application can realize automatic adjustment of the height of the dust sticking roller, and it is only necessary to ensure that the distance between the bottom of the sliding groove 16 and the top of the transmission component is less than or equal to the thickness of the core plate. When the core plate passes through the transmission channel, the dust sticking roller can rise along the sliding groove 16 under the lifting effect of the core plate, and can fall along the sliding groove 16 under the effect of its own gravity, so as to be suitable for dust removal of core plates of different thicknesses, thereby increasing the application range of the dust sticking device.

[0036] When the sticky roller rotates in the present application, the friction force on the core plate causes the core plate to move, and the transmission direction of the sticky roller to the core plate is the same as the transmission direction of the transmission component to the core plate, so that the sticky roller and the transmission component can jointly transmit the core plate.

[0037] In order to ensure that the sticky roller can be smoothly lifted and lowered along with the thickness of the core plate, the present application sets elastic members at both ends of the sticky roller, one end of the elastic member is connected to the bottom of the sticky roller, and the other end is fixed to the bottom of the sliding groove 16. That is to say, when the sticky roller extends horizontally, the elastic member is a vertical elastic member, and the two ends of the elastic member are respectively in contact with the sticky roller and the bottom of the sliding groove 16, and the elastic member can be specifically a spring. When the core plate is thin, under the gravity of the sticky roller and the elastic force of the elastic member, the sticky roller descends, causing the spring to be compressed, and the bottom of the sticky roller is in contact with the upper surface of the core plate. When the core plate is thicker, under the lifting effect of the core plate and the elastic force of the spring, the sticky roller can be ensured to rise smoothly, avoiding excessive gravity of the sticky roller, resulting in the thickness of the transmission channel being less than the thickness of the core plate, and the inability to achieve transmission and cleaning of the core plate.

[0038] Furthermore, the dust-sticking roller of the present application includes an intermediate shaft 12, a rotating bearing 15 and a roller shaft 14, the outer peripheral side of the intermediate shaft 12 is covered with a dust-sticking layer 13, the two ends of the intermediate shaft 12 are respectively connected to the roller shaft 14, the rotating bearing 15 is located at the connection position between the intermediate shaft 12 and the roller shaft 14, and the inner ring of the rotating bearing 15 is fixedly connected to the roller shaft 14, and the outer ring of the rotating bearing 15 is fixedly connected to the intermediate shaft 12; the two roller shafts 14 are respectively located in the sliding grooves 16.

[0039] The sticky layer 13 can be a multi-layer structure, and each layer of the sticky layer 13 can be torn off to expose the inner sticky layer 13. The sticky layer 13 can also be a single-layer structure. After the sticky roller works for a period of time, the sticky roller can be replaced to ensure that the surface of the core board is cleaned and removed.

[0040] The outer side of the intermediate shaft 12 of the present application can be wrapped with multiple layers of dust-sticking layer 13. By tearing off the outermost dust-sticking layer 13, it is possible to avoid frequent replacement of the dust-sticking layer 13 and improve the dust removal efficiency. At the same time, the intermediate shaft 12 of the present application is fixedly connected to the outer ring of the rotating bearing 15, and the first rotating driving member is connected to the outer ring of the rotating bearing 15 or to the intermediate shaft 12, and is used to drive the intermediate shaft 12 and the dust-sticking layer 13 on the outer side to rotate synchronously. The inner ring of the rotating bearing 15 is fixedly connected to the roller shaft 14, and one end of the roller shaft 14 is fixedly connected to the intermediate shaft 12, and the other end is located in the sliding groove 16. The outer ring of the rotating bearing 15 rotates, and the inner ring is fixedly connected to the roller shaft 14, and does not rotate with the outer ring of the rotating bearing 15. The rotating bearing 15 can ensure that the roller shaft 14 is fixed while the intermediate shaft 12 rotates. In this way, the roller 14 does not need to rotate, but only needs to rise and fall in the sliding groove 16, thereby avoiding the rotational friction between the roller 14 and the sliding groove 16, ensuring that the intermediate shaft 12 and the dust-sticking layer 13 rotate more stably, and further improving the dust removal efficiency.

[0041] The side of the intermediate shaft 12 of the present application close to the roller shaft 14 is provided with a retaining edge 17; the side of the retaining edge 17 away from the intermediate shaft 12 is provided with a rubber ring 18. The retaining plate can limit the dust sticking layer 13 to ensure that the position of the dust sticking layer 13 relative to the intermediate shaft 12 is fixed. The rubber ring 18 can achieve a buffer between the rotating bearing 15 and the intermediate shaft 12 to ensure that the dust sticking roller rotates and rises smoothly.

[0042] In the present application, a dust cover is provided on the rotating bearing 15 and the roller 14 , which can protect the rotating bearing 15 and the roller 14 and prevent impurities on the sticky layer 13 from falling into the rotating bearing 15 and affecting the rotation efficiency of the rotating bearing 15 .

[0043] In the present application, the roller shaft 14 is detachably connected to the inner ring of the rotating bearing 15 through a thread, and when the dust-sticking layer 13 on the outer side of the intermediate shaft 12 is used up, the rotating bearing 15, the roller shaft 14 and the intermediate shaft 12 can be removed and replaced with a new intermediate shaft 12. The threaded disassembly structure can improve the replacement efficiency of the intermediate shaft 12 and the dust-sticking layer 13.

[0044] The transmission component described in the present application includes a second rotating driving member and a plurality of transmission rollers 10 arranged in parallel. The extension direction of the transmission roller 10 is perpendicular to the transmission direction of the transmission component. The transmission roller 10 is provided with a roller 11 abutting against the lower surface of the core plate. The roller 11 is fixedly connected to the transmission roller 10. The second rotating driving member is connected to a plurality of transmission rollers 10 at the same time and drives the transmission roller 10 to rotate around its axis.

[0045] A roller 11 is provided in the transmission roller 10, and the roller 11 abuts against the lower surface of the core plate and drives the core plate forward; the upper surface of the core plate abuts against the sticky roller, and the sticky roller also drives the core plate forward under the action of the first rotating drive member, so that the upper and lower sides of the core plate are subjected to the forward friction force, ensuring that the core plate is smoothly transmitted forward.

[0046] In the present application, the roller 11 is fixed in the transmission roller 10 and rotates together with the transmission roller 10, and the rotation direction of the roller 11 is opposite to the rotation direction of the dust-sticking roller, so as to ensure that the friction forces on the upper and lower surfaces of the core plate are in the same direction.

[0047] In the present application, the rollers 11 are distributed at intervals in the transmission rollers, and grooves that do not contact the core plate are formed between adjacent rollers 11. This can reduce the contact area between the lower surface of the core plate and the transmission component, and avoid excessive contact area between the core plate and the transmission component, which may cause contamination and scratches on the surface of the core plate.

[0048] In the present application, the transmission component can also be a transmission belt, and the transmission direction of the core plate driven by the transmission belt is the same as the transmission direction of the dust-sticking roller to the core plate.

[0049] The rotation of the sticky roller of the present application can realize the transmission of the core plate, and can also ensure that the core plate is in full contact with the sticky layer 13. The design of the sliding groove 16 in the present application can make the height of the sticky roller adaptively adjusted, and cooperate with the elastic force of the spring to ensure that when the core plate is thicker, the sticky roller automatically rises; when the core plate is thinner, the sticky roller automatically descends, realizing adaptive adjustment of the position of the sticky roller.

[0050] It can be understood that the above embodiments only express the preferred implementation methods of the present application, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the present application; it should be pointed out that for ordinary technicians in this field, without departing from the concept of the present application, the above-mentioned technical features can be freely combined, and several deformations and improvements can be made, which all belong to the protection scope of the present application; therefore, all equivalent changes and modifications made to the scope of the claims of the present application should belong to the scope covered by the claims of the present application.
