DETAILED DESCRIPTION
[0048] For the purpose of clarity, technical solutions in the embodiments of the present application will be described in more detail below with reference to the drawings of the preferred embodiments of the present application. In the drawings, the same or similar notations represent the same or similar components or components having the same or similar functions throughout.

The embodiments of the present application will be described in detail below with reference to the drawings.
[0049] In the description of the embodiments of the present application, it should be noted that unless otherwise explicitly specified and limited, the terms "mounting", "connection", "connection" should be understood in a broad sense, for example, it can be a fixed connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two elements or the interaction relationship between two elements. For those of ordinary skill in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.
[0050] In the description of the embodiments of the present application, it should be understood that the terms "up", "down", "front", "back", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as limiting the present application.
[0051] In the description of the embodiments of the present application, the meaning of "multiple" is two or more, unless otherwise specified and specified.
[0052] The terms "first", "second", "third", "fourth" and the like in the specification and claims of the present application and the above drawings are used to distinguish similar objects, and do not necessarily describe a particular order or sequence.
[0053] Moreover, the terms "comprising" and "having" and any variations thereof are intended to cover a non-exclusive inclusion, for example, a process, method, system, product or apparatus that comprises a list of steps or units not necessarily limited to those explicitly listed, but can include other steps or units not expressly listed or inherent to such processes, methods, products or apparatus.
[0054] The roller coater is a core component of a coating production line, which is suitable for coating planar materials such as metal plates; the types of coating rollers include coating rubber rollers, coating steel rollers, metering rollers, paint lifting rollers, and doctor blade rollers. When coating, the coating covers the surface of the coating roller to form a wet film, and the wet film is uniformly attached to the surface of the coated object through the rotation of the coating roller.
[0055] In the related art, the roller coater includes a rack and a coating roller. The shaft end of the coating roller has a mounting shaft, and the mounting shaft is mounted on the rack through a bearing. The roller surface of the coating roller is used for coating the coating.
[0056] The shaft end of the coating roller is generally a beveled shaft with a decreasing diameter structure. The coating is a flowing liquid that flows to the lowest point on the shaft end surface according to the height difference, and then flows onto the mounting shaft.
[0057] When the roller coater is running normally, the coating roller rotates at a constant speed. The coating on the surface of the coating roller falls back into the coating box from directly below the coating roller. If there is too much coating on the roller surface, there is still a possibility that the coating will flow from the roller surface to the mounting shaft.
[0058] When the coating roller stops rotating, the coating at the end of the coating roller flows to the end surface of the coating roller due to the action of gravity, and then flows along the mounting shaft to the bearing position. Because the coating has strong viscosity and corrosiveness, it is difficult to clean the long-term accumulation at the bearing position, causing internal corrosion of the bearing, resulting in a decrease in precision, and further leading to an undesirable coating effect. In addition, part of the coating may also drip outside the coating box, causing corrosion and damage to the surface of the equipment.
[0059] In the related art, to block the coating on the roller surface from flowing along the mounting shaft of the coating roller to the bearing position and corroding the bearing, a baffle structure is usually sleeved on the mounting shaft. However, because the coating has strong viscosity and corrosiveness, part of the coating will adhere to the baffle structure after being blocked by the baffle structure, although the coating is prevented from corroding the bearing, but after a long time of use, the baffle structure will also be corroded, and the baffle structure needs to be cleaned and maintained, or even a new baffle structure needs to be replaced.
[0060] In some application scenarios, a plate-shaped structure is usually sleeved on the mounting shaft to block the coating. The connection mode of this baffle structure and the mounting shaft makes it inconvenient to clean the baffle structure, and the cleaning effect is poor. When replacing the baffle structure, the coating roller even needs to be disassembled, which is cumbersome to operate.
[0061] To solve the above technical problems, the embodiment of the present application provides a roller coater, in the technical scheme, the roller coater comprises a rack, a coating roller and a baffle disc structure; the coating roller comprises a coating part and a mounting part connected to the end of the coating part, the coating part is located on the inner side of the rack, and the mounting part is used for being connected to the rack through a bearing; the baffle disc structure is connected to the rack through a connecting mechanism and is located between the coating part and the rack, the baffle disc structure comprises a first baffle disc in the shape of a sector ring and a second baffle disc in the shape of a sector ring, the first baffle disc and the second baffle disc are rotationally connected and jointly surround a through hole; the mounting part penetrates the through hole, and the outer side wall of the mounting part abuts against the inner side wall of the through hole, so that the side wall of the baffle disc structure blocks the coating on the mounting part. After the coating on the coating part flows to the mounting part, the baffle disc structure is arranged as a physical barrier to cut off the channel for the coating to flow from the mounting part to the position of the bearing, so that the coating cannot reach the position of the bearing, and the coating is prevented from corroding the bearing. In addition, the first baffle disc and the second baffle disc are arranged in a split manner, and the first baffle disc and the second baffle disc are rotationally connected, so that the disassembly and assembly of the baffle disc structure can be quickly completed, and then the disassembled baffle disc structure can be conveniently cleaned and replaced.
[0062] It should be noted that, Figures 1 to 5 The schematic diagram of the roller coater is shown, and the specific structure of the remaining parts of the roller coater is not limited to Figures 1 to 5 The example.
[0063] The present application will be described in detail below with reference to the drawings and specific embodiments:
[0064] Referring to Figure 1 , Figure 2 and Figure 3 , the embodiment of the present application provides a roller coater, which comprises a rack 100, a coating roller 200 and a baffle disc structure 300; wherein the rack 100 provides a mounting position for the coating roller 200, and the rack 100 can be a truss formed by profiled members or a plate structure, and the structure of the rack 100 is not limited in the embodiment of the present application.
[0065] The coating roller 200 comprises a coating part 210 and a mounting part 220 connected to the end of the coating part 210, and the circumferential side wall of the coating part 210 is the roller surface of the coating roller 200 and is used for coating the coating. The mounting part 220 provided at the end of the coating part 210 has a smaller diameter than the coating part 210, so as to facilitate the installation of the coating roller 200. Further, the two ends of the coating part 210 are both provided with the mounting part 220, the coating part 210 is located on the inner side of the rack 100, and the mounting part 220 is used for being connected to the rack 100 through a bearing 10; that is, the two mounting parts 220 are rotationally connected to the rack 100 through the bearings 10.
[0066] The baffle plate structure 300 is connected with the rack 100 through the connecting mechanism 400 and is located between the coating part 210 and the rack 100. In order to avoid interference between the coating part 210 and the rack 100, a certain spacing is usually arranged between the coating part 210 and the rack 100, and the baffle plate structure 300 is located in the spacing between the coating part 210 and the rack 100. The baffle plate structure 300 has a through hole 301; the mounting part 220 penetrates the through hole 301, and the outer side wall of the mounting part 220 abuts against the inner side wall of the through hole 301, so that the side wall of the baffle plate structure 300 blocks the coating on the mounting part 220.
[0067] In a specific implementation, the baffle plate structure 300 includes a first fan-shaped baffle plate 320 and a second fan-shaped baffle plate 330, and the first fan-shaped baffle plate 320 and the second fan-shaped baffle plate 330 are rotationally connected and jointly surround the through hole 301.
[0068] In the above embodiment, after the coating on the coating part 210 flows to the mounting part 220, the baffle plate structure 300 is arranged as a physical barrier, the through hole 301 of the baffle plate structure 300 is tightly matched with the outer wall of the mounting part 220 of the coating roller 200, the channel for the coating to flow from the mounting part 220 to the bearing 10 is cut off, and the coating cannot reach the position of the bearing 10; the long-term accumulation of the coating at the position of the bearing 10 is avoided, and further, the corrosion of the corrosive coating to the inside of the bearing 10 is avoided, and the precision and service life of the bearing 10 are ensured.
[0069] In a specific implementation, the roller coater provided in the present application includes two baffle plate structures 300, the two baffle plate structures 300 are located on the two sides of the coating part 210 respectively, and the two baffle plate structures 300 correspond to the two mounting parts 220 one by one. The coating on both ends of the coating part 210 can be guaranteed to be blocked, the coating is prevented from contacting the bearing 10, and the stable operation of the coating roller 200 is ensured.
[0070] It should be noted that the through hole 301 of the baffle plate structure 300 is tightly matched with the outer wall of the mounting part 220 of the coating roller 200, the mounting part 220 can be fixed relative to the baffle plate structure 300 or can rotate relative to the baffle plate structure 300. When the mounting part 220 rotates in the through hole 301, the through hole 301 of the baffle plate structure 300 is in rolling abutment with the outer wall of the mounting part 220 of the coating roller 200.
[0071] In a possible implementation, in order to prevent the splashed coating from splashing onto other components, a coating box 600 is arranged on the inner side of the rack 100, and the coating box 600 is located below the coating part 210. Specifically, the projection of the baffle plate structure 300 towards the coating box 600 is located in the coating box 600. In this way, not only the coating on the coating part 210 can directly drop into the coating box 600, but also the coating blocked by the baffle plate structure 300 can drop into the coating box 600.
[0072] In a possible implementation, the baffle plate structure 300 further comprises a connecting piece 310 connected with the connecting mechanism 400. In combination with Figure 4 and Figure 5 As shown, the connecting piece 310 comprises a first connecting part 311 and a second connecting part 312 connected in rotation; one end of the fan ring-shaped first baffle plate 320 is connected with the first connecting part 311, and one end of the fan ring-shaped second baffle plate 330 is connected with the second connecting part 312. Here, the fan ring-shaped can be understood as a partial structure of a ring, and the fan ring-shaped has a central angle, and the central angle of the first baffle plate 320 and the central angle of the second baffle plate 330 are both 180 degrees, so that the first baffle plate 320 and the second baffle plate 330 are arranged to form a complete ring. Further, the baffle plate structure 300 is arranged to wrap the mounting part 220 of the coating roller 200 in the circumferential direction, thereby improving the effect of blocking the coating.
[0073] The end of the first baffle plate 320 away from the first connecting part 311 is clamped with the end of the second baffle plate 330 away from the second connecting part 312, so that the first baffle plate 320 and the second baffle plate 330 are arranged to form a through hole 301 together.
[0074] In the above embodiment, by arranging the fan ring-shaped split structure, the first baffle plate 320 and the second baffle plate 330 are combined to form a complete ring, and the first baffle plate 320 and the second baffle plate 330 are rotatably connected at one end and clamped at the other end, which can facilitate the disassembly of the staff. In specific operation, first, the clamping of the first baffle plate 320 and the second baffle plate 330 is released, then one of the first baffle plate 320 and the second baffle plate 330 is rotated or both of them are rotated, so that the through hole 301 is opened, and the baffle plate structure 300 can be removed from the mounting part 220, which facilitates the staff to clean the baffle plate structure 300. Alternatively, after the through hole 301 is opened, the staff can conveniently replace the coating roller 200, and after the new coating roller 200 is replaced, the through hole 301 is closed again to complete the installation of the baffle plate structure 300.
[0075] Referring to Figure 3 As shown, in a possible implementation, at least one drainage groove 302 is arranged on the side of the baffle plate structure 300 facing the coating part 210, and the drainage groove 302 is arranged in the vertical direction. Specifically, a plurality of drainage grooves 302 are arranged, and the plurality of drainage grooves 302 are arranged in the horizontal direction.
[0076] In the above embodiment, when the coating flows from the coating part 210 to the mounting part 220, the coating on the mounting part 220 will first contact the side wall of the baffle plate structure 300 facing the coating part 210, at which time the coating will enter the drainage groove 302. Since the extension direction of the drainage groove 302 is the vertical direction, under the action of gravity, the coating is guided to flow. The continuous drainage of the coating on the mounting part 220 is realized.
[0077] In a possible implementation, with continuous reference to Figure 4 and Figure 5 As shown in the figure, the first connecting part 311 and the second connecting part 312 are both arc-shaped plates, one of the first connecting part 311 and the second connecting part 312 is provided with a rotating shaft 3121 at the end thereof close to the other, and the other is provided with a rotating ring 3111, the rotating ring 3111 is sleeved on the rotating shaft 3121, and the rotating ring 3111 is arranged in a spaced manner with the first baffle 320 or the second baffle 330. Specifically, the rotating ring 3111 is arranged on the first connecting part 311, and the rotating shaft 3121 is arranged on the second connecting part 312, the rotating ring 3111 is coaxially sleeved with the rotating shaft 3121, the rotating connection of the first connecting part 311 and the second connecting part 312 is realized, the structure is relatively simple, and the manufacturing cost can be reduced.
[0078] In the above embodiment, the first connecting part 311 and the second connecting part 312 adopt arc-shaped plates instead of straight plates, and the relative rotation is realized through the cooperation of the rotating shaft 3121 and the rotating ring 3111, which effectively compensates for the axial displacement of the coating roller 200 caused by temperature change and load fluctuation. In addition, the rotating ring 3111 is arranged in a spaced manner with the first baffle 320 / second baffle 330, so that the rotating connection point of the first connecting part 311 and the second connecting part 312 is arranged in a spaced manner with the first baffle 320 or the second baffle 330, which provides a clearance for the rotation of the first baffle 320 and the second baffle 330, and avoids interference between parts.
[0079] In a possible implementation, the end surface of the first baffle 320 is provided with a clamping piece 303, the end surface of the second baffle 330 is provided with a clamping groove 304, and the clamping piece 303 is configured to be adsorbed in the clamping groove 304 by magnetic attraction. The clamping piece 303 can be a column or a half column, the clamping groove 304 is matched with the clamping piece 303, and the clamping piece 303 can be a magnetic piece, for example, the clamping piece 303 is a magnet, and a metal coating layer can be coated on the inner wall of the clamping groove 304. The clamping of the clamping piece 303 and the clamping groove 304 is realized by using magnetic attraction, so as to fix the first baffle 320 and the second baffle 330.
[0080] In the above embodiment, the automatic centering and fitting of the first baffle 320 and the second baffle 330 is realized by using magnetic attraction, the complete fitting of the end surfaces of the first baffle 320 and the second baffle 330 is ensured by magnetic force guidance, misalignment caused by manual fixing operation is avoided, and continuous and uniform pressing force can be provided by using magnetic attraction to prevent loosening.
[0081] In a possible implementation, with reference to Figure 4As shown, the connecting mechanism 400 comprises a base assembly 410 and a connecting assembly 420; the base assembly 410 is connected with the rack 100, and the base assembly 410 has a mounting slot 4101; part of the connecting assembly 420 is inserted into the mounting slot 4101 along the extension direction of the mounting slot 4101; and the connecting assembly 420 is connected with the baffle plate structure 300.
[0082] In the above embodiment, the base assembly 410 is provided with the mounting slot 4101, and the connecting assembly 420 is inserted into the mounting slot 4101 along the extension direction of the mounting slot 4101; the mounting slot 4101 serves as a guide reference to ensure that the connecting assembly 420 is installed to the correct position, and the plug-in operation avoids human error in installation. And this realizes the detachable connection of the connecting assembly 420.
[0083] In this way, by setting the detachable connection between the connecting assembly 420 and the base assembly 410, the worker can easily disassemble the connecting assembly 420 and the baffle plate structure 300 to clean the baffle plate structure 300. Moreover, various specifications of the baffle plate structure 300 can be set to adapt to different shaft diameters of the coating roller 200, without the need to disassemble the base assembly 410, but only to remove the connection between the base assembly 410 and the connecting assembly 420.
[0084] In specific implementation, the connecting assembly 420 comprises a first connecting plate 421, a second connecting plate 422 and a third connecting plate 423 connected in sequence; the first connecting plate 421 and the third connecting plate 423 are located on the same side of the second connecting plate 422, and the first connecting plate 421 and the third connecting plate 423 are arranged at intervals; part of the first connecting plate 421 is inserted into the mounting slot 4101; and the third connecting plate 423 is rotationally connected with the baffle plate structure 300. Here, the first connecting plate 421 and the second connecting plate 422 can be integrally formed, which helps to improve the connection strength. The third connecting plate 423 can also be integrally formed with the second connecting plate 422, or connected with the second connecting plate 422 through bolts or other components. In order to improve the connection strength, a structural rib 500 is further arranged between the third connecting plate 423 and the second connecting plate 422, which effectively avoids the influence of vibration during the operation of the roller coater.
[0085] In the above embodiment, the third connecting plate 423 is rotationally connected with the baffle plate structure 300, and it can be understood that even if the projection of the third connecting plate 423 towards the mounting portion 220 is not inside the mounting portion 220, the baffle plate structure 300 can adjust the position through slight rotation to ensure that the baffle plate structure 300 is stably sleeved on the mounting portion 220. When the coating roller 200 produces slight deviation due to load, by setting the third connecting plate 423 to be rotationally connected with the baffle plate structure 300, the position of the baffle plate structure 300 can be adjusted in real time, the concentricity of the baffle plate structure 300 and the mounting portion 220 is maintained, the vibration and impact during the operation of the equipment are offset, stress concentration is avoided, and the service life of the components is prolonged.
[0086] In a possible implementation, the baffle plate structure 300 has a rotating hole 305; one end of the third connecting plate 423 towards the baffle plate structure 300 has two connecting ears 424 arranged in a spaced and opposite manner along the axis direction of the coating roller 200, and a connecting shaft 425 is arranged between the two connecting ears 424; the connecting shaft 425 is inserted into the rotating hole 305.
[0087] In the above embodiment, the rotating hole 305 is coaxially arranged in the rotating shaft 3121, and the connecting shaft 425 is inserted into the rotating hole 305 of the rotating shaft 3121. Specifically, the connecting ears 424 are arranged in a vertical direction, the connecting shaft 425 is arranged in a horizontal direction, and the extension direction of the connecting shaft 425 is parallel to the axis of the mounting portion 220. The connecting shaft 425 directly restricts the relative position of the baffle plate structure 300 and the third connecting plate 423, avoiding large deviation of the baffle plate structure 300.
[0088] In a possible implementation, the opposite side of each of the two connecting ears 424 is provided with a sliding groove 4241 extending in a vertical direction, and the two ends of the connecting shaft 425 are located in the sliding grooves 4241, respectively.
[0089] Here, by arranging the sliding grooves 4241 extending in a vertical direction, the connecting shaft 425 can move in the sliding grooves 4241. When the roller coater is running, vertical vibration may occur, at which time the baffle plate structure 300 can also move with the vibration of the machine, and the connecting shaft 425 can slightly move in the sliding grooves 4241, avoiding concentrated stress on the baffle plate structure 300 and prolonging the service life of the parts. It should be noted here that the length of the sliding groove 4241 needs to be flexibly selected according to the design, for example, the length of the sliding groove 4241 is 1.5 times the diameter of the connecting shaft 425, which needs to ensure that the shaft end of the connecting shaft 425 does not deviate from the sliding groove 4241.
[0090] In a possible implementation, the base assembly 410 includes a flange 411 and a connecting seat 412 connected to each other; the flange 411 is connected to the rack 100, and the connecting seat 412 is located on the side of the flange 411 away from the rack 100. The flange 411 can be connected to the rack 100 by a plurality of bolts, and the plurality of bolts can uniformly disperse the connecting force to ensure the stability of the structure. The flange 411 and the connecting seat 412 can be integrally cast.
[0091] The connecting seat 412 is provided with a mounting groove 4101 in a vertical direction; in this way, the first connecting plate 421 can be inserted and pulled out in the mounting groove 4101 in a vertical direction, avoiding interference between the connecting assembly 420 and other parts.
[0092] The base assembly 410 further comprises a fastening bolt 413, a threaded hole communicating the mounting groove 4101 with the external environment is arranged on the side wall of the connecting seat 412; the fastening bolt 413 is threadedly connected with the threaded hole, one end of the fastening bolt 413 is located in the mounting groove 4101 and tightly abuts against the connecting assembly 420.
[0093] In the above embodiment, after the first connecting plate 421 is inserted into the mounting groove 4101, the fastening bolt 413 is screwed, one end of the fastening bolt 413 tightly abuts against the first connecting plate 421, the pressure can be applied to the first connecting plate 421, the first connecting plate 421 is stably inserted into the mounting groove 4101, and the connection stability is improved.
[0094] In a possible embodiment, the end of the first connecting plate 421 is provided with a guide inclined surface 4211, which can guide the first connecting plate 421 to be smoothly inserted into the mounting groove 4101.
[0095] In a possible embodiment, without changing the existing rack 100 and coating roller 200, the connecting mechanism 400 and the disc structure 300 can be directly installed on the existing rack 100 as additional parts, for example, the flange 411 is installed on the rack 100, the base assembly 410 provides a mounting base, then the first connecting plate 421 of the connecting assembly 420 is inserted into the mounting groove 4101, at this time, the first disc 320 or the second disc 330 is rotated, then nested on the outer circumferential side of the mounting portion 220, and the first disc 320 and the second disc 330 are fixed by the magnetic attraction force, and the installation is completed. After being used for a period of time, the fixing of the first disc 320 and the second disc 330 is released, the fastening bolt 413 is loosened, the first connecting plate 421 is pulled out upward, and the disassembly of the connecting assembly 420 is completed. At this time, the worker can clean the disc structure 300, and finally reinstall the connecting assembly 420 and the disc structure 300.

[0097] After the paint on the coating part 210 flows to the mounting part 220, the passage of the paint flowing from the mounting part 220 to the position of the bearing 10 is cut off by setting the baffle structure 300 as a physical barrier, so that the paint cannot reach the position of the bearing 10, avoiding the paint from corroding the bearing 10. In addition, by setting the first baffle 320 and the second baffle 330 in a split body and by setting the first baffle 320 and the second baffle 330 to be rotationally connected, the disassembly and assembly of the baffle structure 300 can be quickly completed, and then the disassembled baffle structure 300 can be conveniently cleaned and replaced.
