DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the utility model will be apparently and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0023] Referring to Figs. 1 to 4

[0024] A kind of anti-blocking roll plating roller with self-cleaning function, including roller body 1 and scraping blade 2, the barrel wall of roller body 1 is uniformly distributed with several through slots 3 passing through the inside and outside of roller body 1, the end of scraping blade 2 is provided with wedge-shaped scraping edge 21. Preferably, the material of scraping blade 2 is material with certain elasticity and wear resistance, such as rubber or elastic plastic, to ensure that it can effectively remove blockages and has a long service life.

[0025] For the convenience of description, the direction when the roller body 1 rotates forward is defined as front, and vice versa.

[0026] Each of the through-slots 3 is rectangular, and each of the through-slots 3 comprises a first side wall 31 and a second side wall 32 arranged along the axial direction of the drum body 1, and a third side wall 33 and a fourth side wall 34 arranged along the direction perpendicular to the axial direction of the drum body 1, the first side wall 31 is arranged at the rear end of the second side wall 32, and the first side wall 31, the second side wall 32, the third side wall 33 and the fourth side wall 34 enclose a containing space 35 for arranging the wiper blade 2. Further, the length of the wiper blade 2 is slightly greater than the farthest distance in the containing space 35, so that the wedge-shaped scraping edge 21 can clearly control any angle in the space 35; due to the diagonal distance away, the farthest distance in the containing space 35 is the diagonal distance between the first side wall 31 and the second side wall 32, which inevitably makes the vertical distance between the first side wall 31 and the second side wall 32 less than the diagonal distance, and when the wiper blade 2 scrapes the second side wall 32, the wiper blade 2 made of elastic material will be relatively shortened, so that the wedge-shaped scraping edge 21 can clearly control any angle in the space 35.

[0027] The two ends of the wiper blade 2 are respectively hinged to the third side wall 33 and the fourth side wall 34 through a hinge mechanism, and the hinge mechanism is arranged at the outer edge close to the first side wall 31. It is worth noting that the hinge mechanism in the embodiment is a pin shaft 22 penetrating through the two ends of the wiper blade 2 and hinged to the third side wall 33 and the fourth side wall 34.

[0028] Further, a first limiting piece 11 for limiting the rotation of the wiper blade 2 is arranged on the outer side wall of the drum body 1, and the first limiting piece 11 is arranged on the first side wall 31. The first limiting piece 11 avoids the wiper blade 2 from being separated from the area of the containing space 35 when the wiper blade 2 rotates backward around the pin shaft 22.

[0029] Further, a second limiting piece 12 for placing the wedge-shaped scraping edge 22 is arranged on the inner side wall of the drum body 1, the second limiting piece 12 extends inward along the first side wall 31, and the surface of the second limiting piece 12 is flush with the surface of the first side wall 31. The second limiting piece 12 avoids the wedge-shaped scraping edge 21 from being damaged due to high centrifugal force. It is worth noting that the first limiting piece 11 and the second limiting piece 12 in the embodiment can be integrally formed with the drum body 1.

[0030] Further, a fixed support 4 is further sleeved on the outer periphery of the drum body 1, the fixed support 4 comprises a fixed plate 41 extending along the axial direction of the drum body 1, and connecting plates 42 respectively connected to the two ends of the fixed plate 41, and the two connecting plates 42 are connected to the drum body 1 through rotating shafts 43. The fixed plate 41 is provided with at least one first waste groove 44 extending along the axial direction of the drum body 1, and the first waste groove 44 penetrates through the two sides of the fixed plate 41.

[0031] A bristle assembly 5 is provided on the side of the fixing plate 41 facing the roller body 1. The bristle assembly 5 is detachably connected to the fixing plate 41. The bristle assembly 5 includes a plurality of nylon bristles 51 and a support plate 52 that supports the plurality of nylon bristles 51. The support plate 52 is in contact with the fixing plate 41, and a second waste trough 53 is also provided at the position corresponding to the first waste trough 44.

[0032] Furthermore, the bottom of the roller body 1 is provided with a collection trough (not shown in the figure) for collecting waste materials, and the collection trough is located below each of the first waste troughs 44 and the second waste troughs 53.

[0033] Working principle

[0034] During normal electroplating operation, the drum body 1 rotates in the forward direction. The scraper 2 is affected by centrifugal force and, with the help of the characteristics of the pin 22, it adheres tightly to the first side wall 31. At this time, the electroplating solution can normally enter the interior of the drum body 1 through the through groove 3 and electroplat the workpiece, ensuring the normal electroplating process.

[0035] When cleaning is required, the roller body 1 is controlled to rotate in the opposite direction. At this time, the scraper 2 is affected by centrifugal force and rotates around the pin 22, so that the scraper 2 rotates in the accommodating space 35 in a direction away from the first side wall 31, and scrapes off the oil, debris, plating peeling and other waste that are attached to and blocked in the through groove 3. At the same time, the scraped waste is driven by the scraper 2 and rubs against the nylon bristles 51 on the fixed bracket 4, further scraping off the remaining debris in the through groove 3. Finally, the cleaned waste bounces down to the bottom collection tank 6 under the action of centrifugal force and its own gravity, completing the cleaning process.

[0036] By adopting the aforementioned design scheme, the beneficial effects of this utility model are:

[0037] 1. This utility model adopts a purely mechanical structure. By adding a scraper 2 in the through groove 3 on the basis of the original roller body 1, the cleaning function can be achieved without additional driving devices such as motors or air pumps, which greatly reduces the equipment cost. At the same time, due to the reduction of complex driving components, the failure rate of the equipment is also significantly reduced, improving the stability and reliability of the equipment.

[0038] 2. The ingenious design of the forward and reverse rotation of the drum body 1 achieves bidirectional utilization of centrifugal force. When the drum body 1 rotates forward, the centrifugal force causes the scraper 2 to rotate forward and press against the first side wall 31, ensuring that the electrolyte can enter the drum normally and interact with the workpiece during the electroplating process, thus ensuring the quality of electroplating. When the drum body 1 rotates in reverse, the centrifugal force causes the scraper 2 to rotate backward and unfold within the accommodating space 35, triggering the cleaning function and effectively removing the blockages in the through groove 3, thus achieving an organic combination of cleaning and electroplating functions.

[0039] 3. This utility model is compatible with existing barrel plating equipment. Only the structure of the barrel body 1 needs to be modified. There is no need to replace or adjust the entire barrel plating equipment on a large scale. It has strong compatibility and practicality and can save enterprises a lot of equipment replacement costs.

[0040] 4. After actual testing, after adopting the structure of this utility model, the clogging rate of the through tank 3 of the barrel plating equipment was reduced by 80%, the stability of electrolyte flow was improved by 40%, and the frequency of manual cleaning was extended from once a day to once a week, which greatly improved production efficiency and product quality.
