[0056] Exemplary embodiments of the utility model will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the utility model are shown in the drawings, it should be understood that the utility model can be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided to enable a more thorough understanding of the utility model and to fully convey its scope to those skilled in the art.
[0057] like Figures 1 to 7 As shown, an anti-jamming guide wheel device includes: a guide wheel 1 and a central shaft 2 rotatably connected to the center, a disc 3 rotatably disposed on the outer side of the central shaft 2, characterized in that: a vertical plate 4 is disposed on the outer side of the disc 3, and the vertical plate 4 is located above the disc 3, and a docking plate 5 is disposed above the vertical plate 4;
[0058] An anti-jamming part is installed below the docking plate 5 and on the inner wall of the upright plate 4 to prevent the guide wheel from jamming.
[0059] The anti-jamming part includes an upper through part and a lower through part. The upper through part is located below the docking plate 5 and the upper through part and the lower through part are connected. The lower through part is located on the inner wall of the vertical plate 4.
[0060] A lubricating component is provided between the mating plate 5 and the upper through part to lubricate the guide wheel.
[0061] During operation, when the guide wheel gets stuck, the utility model embodiment is used.
[0062] Generally, there are two locations where the device is stuck:
[0063] In the first scenario, the gap between guide wheel 1 and vertical plate 4;
[0064] When the upper part is powered on, one of its components rotates, and the rotation causes one component to move closer to another component. The outward squeezing force is generated according to the tendency of the movement when they move closer. The squeezing force pushes the part used for unblocking to insert into the gap between the guide wheel 1 and the vertical plate 4. The unblocking is completed through frequent insertion and insertion, preventing jamming.
[0065] The second scenario involves the gap between guide wheel 1 and the protective cover frame;
[0066] When the upper part is squeezed outward, the displaced part contacts the lower part and meshes with it. Under the action of meshing, it rotates. After the lower part rotates, it gradually scrapes the gap between the guide wheel 1 and the protective cover frame. Through the scraping action, the guide wheel 1 is prevented from being jammed, and the smoothness of use is improved. It should be noted that the docking plate 5 has a male and female plug structure and can be docked together.
[0067] like Figures 2 to 4 As shown, the upper part includes:
[0068] The protective outer shell 51 is fixedly installed below the docking plate 5;
[0069] The folding plate 52 is located below the protective housing 51;
[0070] Plastic sheet 53 is fixedly installed on the inner wall of folding plate 52 and located below folding plate 52;
[0071] The return spring 54 is fixedly installed between the docking plate 5 and the protective shell 51.
[0072] The rotating shaft 50 is located on the outside of the protective housing 51 and passes through the folding plate 52 and the protective housing 51;
[0073] A tension spring 59 is fixedly installed at one end of the protective housing 51;
[0074] The scraper plate 55 is fixedly installed at one end of the tension spring 59;
[0075] Thin strip 56 is positioned above plastic sheet 53;
[0076] Push bar 58 is positioned above thin bar 56;
[0077] The guide rail 57 is set on the inner wall of the protective housing 51 and is penetrated by the push bar 58;
[0078] The removal plate 55 is located on the inner wall of the vertical plate 4;
[0079] A servo motor is installed at one end of the rotating shaft 50 and is connected to the servo motor drive end.
[0080] During operation, when clearing the guide wheel 1, two situations need to be addressed: the gap between the guide wheel 1 and the upright plate 4, and the gap between the guide wheel 1 and the protective shell 51. Using the utility model embodiment, firstly, the rotating shaft 50 is driven to rotate by power. After the rotating shaft 50 rotates, it drives the folding plate 52 to rotate counterclockwise. The folding plate 52, together with the plastic plate 53, gradually moves towards the protective shell 51. The plastic plate 53 squeezes the thin strip 56, and the thin strip 56 pushes the pusher 58 to move along the guide rail 57. The pusher 58, together with the scraper plate 55, inserts into the gap between the guide wheel 1 and the upright plate 4. The tension spring 59 is used to buffer and reset the scraper plate 55. After the scraper plate 55 is inserted, the part of the guide wheel 1 that is stuck is cleared, preventing it from getting stuck.
[0081] When the plastic sheet 53 swings, it will collide with the protective shell 51. After being impacted, the protective shell 51 will shift upward, causing the protective shell 51 to compress the return spring 54. The return spring 54 changes from an extended state to a compressed state to provide cushioning assistance.
[0082] like Figures 5 to 6 As shown, the lower component includes:
[0083] Mounting base 41, there are two, and they are symmetrically fixed to the inner wall of the upright plate 4;
[0084] The guide rod 43 is fixedly installed between the two mounting bases 41 and is located above the mounting bases 41;
[0085] There are two collars 44, which are located on the outside of the guide rod 43.
[0086] The lever 45 is fixedly installed between the two collars 44;
[0087] Rack 46 is fixedly installed on the outside of the lever plate 45;
[0088] The guide rod 43 is rotatably connected to the collar 44.
[0089] Mounting base 41 is L-shaped;
[0090] The rack 46 has multiple teeth and engages with the pusher 58.
[0091] The scraper 45 has an arc-shaped sheet structure for easy scraping;
[0092] Mounting base 41 is fixedly connected to upright plate 4, which facilitates support for guide rod 43.
[0093] When the gap between the guide wheel 1 and the protective housing 51 needs to be cleaned, using the utility model embodiment, the thin strip 56 pushes the pusher 58 to move. At this time, when the pusher 58 moves, it will rub against the rotating shaft 50. The teeth on the pusher 58 mesh with the teeth of the rotating shaft 50, causing the rotating shaft 50 to twist. The rotating shaft 50 drives the dial plate 45 to rotate. The dial plate 45 gradually scrapes the gap between the guide wheel 1 and the protective housing 51. Through the scraping action, the equipment can quickly clean the gap and achieve the purpose of rapid processing.
[0094] like Figure 7 As shown, the lubrication components include:
[0095] The nozzle 511 is positioned above the protective housing 51 and penetrates the protective housing 51;
[0096] Rubber bladder 512 is fixedly installed below docking plate 5.
[0097] Lubricating components also include:
[0098] Rubber bladder 512 may come into contact with protective shell 51;
[0099] The protective housing 51 has holes on its outer side that are adapted to the nozzle 511.
[0100] When the outer side of the guide wheel 1 needs to be processed, the folding plate 52 drives the plastic plate 53 to rotate. When the plastic plate 53 rotates, it will contact the protective shell 51. The protective shell 51 is impacted and moves upward. The protective shell 51 squeezes the spray column 512, and the liquid inside the spray column 512 flows out and flows downward through the bladder 511, thereby ensuring the lubrication of the bottom of the guide wheel 1 and ensuring smoother rotation. At the same time, it can effectively reduce the frictional resistance of the roller when rotating, thereby greatly reducing the frictional loss of the fixed shaft and reducing the probability of the guide wheel getting stuck.
[0101] Working principle: This anti-jamming guide wheel device ensures smooth operation of the guide wheel through the coordinated operation of the anti-jamming part and the lubrication parts.
[0102] When the guide wheel gets stuck in the gap between the guide wheel 1 and the upright plate 4, the upper passage of the anti-jamming part comes into play. The rotating shaft 50 of the upper passage rotates under the drive of the servo motor, which drives the folding plate 52 to rotate counterclockwise. The plastic plate 53 then moves closer to the protective shell 51, and the squeezing strip 56 pushes the pusher 58 to move along the guide rail 57. This, in turn, links the removal plate 55 to the gap, and the tension spring 59 assists in buffering and resetting, thus clearing the blockage and preventing jamming.
[0103] If the guide wheel 1 gets stuck in the gap between the guide wheel 1 and the protective cover frame, when the upper part is in operation, the push bar 58 moves and meshes with the rack 46 of the lower part, driving the deflector 45 to rotate and scrape and clean the gap to avoid getting stuck.
[0104] In addition, the lubrication components ensure the smooth operation of the device. The folding plate 52 drives the plastic plate 53 to rotate and impact the protective shell 51, causing it to move upward and squeeze the spray column 512. The internal liquid flows out through the bladder 511, lubricating the bottom of the guide wheel 1, reducing frictional resistance and wear, and lowering the probability of jamming.
[0105] The foregoing has shown and described the basic principles, main features, and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the utility model. Various changes and modifications can be made to the utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of the utility model is defined by the appended claims and their equivalents.
