[0027] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings.
[0028] like Figure 1-3 As shown, a transfer device for polishing the inner wall of a long tube according to the present invention includes a frame 1, a material transfer mechanism 2, and a material transfer mechanism 5;
[0029] The frame 1 is provided with one or more material transfer mechanisms 2. The material transfer mechanism 2 includes a transfer roller group 3 and a material transfer guide assembly 4. The material transfer guide assembly 4 is located on one side of the transfer roller group 3.
[0030] The transfer roller group 3 includes several transfer rollers 31, which are arranged side by side on the frame 1. The tube 9 is positioned between two adjacent transfer rollers 31, and the two adjacent transfer rollers 31 are a single polishing positioning group.
[0031] The material conveying and guiding assembly 4 includes a guide plate 41, a material conveying connecting frame 42, and a top material cylinder 47. The top material cylinder 47 is connected to the guide plate 41 through the material conveying connecting frame 42. The guide plate 41 is provided with a plurality of guide slopes 42 that can convey the pipes 9 one by one to the discharge end of the conveying roller group.
[0032] The guide slope 42 is inclined upward, and the number of guide slopes 42 is matched with the number of transmission rollers 31. The highest position of the guide slope 42 is the top material end, which is biased towards the feed side of the vertical surface of the corresponding single polishing positioning group.
[0033] The two ends of the guide plate 41 are the feeding part 44 and the discharge slope 43, respectively. The feeding part 44 is located on the feeding side of the transmission roller group 3, and the discharge slope 43 is located on the discharge side of the transmission roller group 3. The side of the frame 1 is provided with a material collection rack 11. The material collection rack 11 is provided with a downward inclined material collection guide slope 111. The lowest end of the material collection guide slope 111 is provided with a baffle plate 112. The discharge slope 43 faces the material collection guide slope 111.
[0034] like Figure 4 As shown, the guide plate 41 is initially positioned below the pipe fitting 9, as... Figure 5 As shown, the top-loading cylinder 47 lifts the guide plate 41, lifting the pipe fittings 9 in each polishing station. The pipe fittings 9 leave each transfer roller 31 and move along the corresponding guide slope 42 towards the next polishing station, as shown. Figure 6-7 As shown, after the pipe 9 slides to the lowest end of the corresponding guide slope 42, the top material cylinder 47 controls the guide plate 41 to descend and reset. The pipe 9 disengages from the guide plate 41 and slides along the roller surface of the corresponding transmission roller 31 to the next polishing positioning group to continue the next polishing. The pipe 9 that has been polished (located on the discharge side of the transmission roller group 3) slides along the discharge slope 43 and falls into the collection guide slope 111 below. The pipe 9 slides along the collection guide slope 111 to the baffle plate 112 to complete the discharge and collection.
[0035] The material transfer guiding assembly 4 also includes a first guiding assembly 46, through which the guide plate 41 is connected to the material transfer connecting frame 42. The first guiding assembly 46 can be a guide rod and a linear bearing assembly. The first guiding assembly 46 guides the lifting and lowering of the guide plate 41, preventing the guide plate 41 from deviating and affecting the material transfer position.
[0036] The material transfer mechanism 5 includes a rotating connecting frame 53, several pressing cylinders 52, and several pressing rollers 51. The pressing cylinders 52 are connected to the pressing rollers 51 through the connecting frame 53. The pressing cylinders 52 and the pressing rollers 51 form a pressing group. Several pressing groups are arranged in parallel on the connecting frame 53. The number of pressing groups is adapted to the number of polishing positioning groups.
[0037] The material transfer mechanism 5 is located above one of the conveyor roller groups 3. The frame 1 is equipped with a material transfer drive assembly 121, which is connected to one of the conveyor roller groups 3. The material transfer drive assembly 121 can use an existing chain drive assembly, with a motor providing power to rotate the connected conveyor roller group 3, thereby causing the pipe to rotate.
[0038] During polishing, the pressure cylinder 52 controls the pressure roller 51 to press down, positioning the tube 9 between the pressure roller 51 and the transfer roller 31. The corresponding transfer roller 31 drives the tube 9 to rotate under the action of the material transfer drive assembly 12, thereby improving the polishing effect.
[0039] A second guide assembly 54 is connected between the pressure roller 51 and the rotating connecting frame 53. The second guide assembly 54 can be a guide rod and a linear bearing assembly. The second guide assembly 54 guides the lifting and lowering of the pressure roller 51 and prevents the pressure roller 51 from being misaligned.
[0040] Longer pipe fittings 9 may have their ends warped, affecting polishing. Both ends of the pipe fitting 9 are equipped with material transfer mechanisms 2 and material transfer mechanisms 5 are close to the polishing insertion end of the pipe fitting 9. While enabling the pipe fitting 9 to rotate continuously, the pipe opening of the pipe fitting 9 is positioned to prevent the polishing insertion end of the pipe fitting 9 from warping, making it easier for the polishing component 7 to be accurately inserted into the pipe fitting 9.
[0041] Both the transfer roller 31 and the pressure roller 51 are nylon rollers, which reduces wear on the outer wall of the pipe 9.
[0042] This utility model discloses a transfer device for polishing the inner wall of a long tube. The tube 9 is placed on the polishing positioning group on the feeding side of the transfer roller group 3. The pressure roller 51 of the transfer mechanism 5 presses down on the end of the tube 9 to facilitate the connection between the polishing head and the end of the tube 9. The tube 9 rotates continuously on the transfer roller group 3 under the action of the transfer drive component 121 below, and the inner wall of the tube 9 is polished. After polishing, the pressure roller 51 rises and resets, and the transfer guide component 4 transfers the corresponding tube 9 to the next polishing positioning group. Meanwhile, the tube 9 in the polishing positioning group on the discharge side has completed the last polishing and is transferred by the transfer guide component 4 to the collection rack 11 for processing and collection.
[0043] The preferred embodiments of this utility model have been described in detail above, but this utility model is not limited to the embodiments described. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of this utility model, and these equivalent modifications or substitutions are all included within the scope defined by the claims of this application.
