Description

Technical Field

[0001] The utility model relates to tire production equipment, in particular to a sidewall turning device for changing the cold pasting of a white sidewall cover film to online hot pasting. Background Technique

[0002] During the tire production process, the production process of the white sidewall is relatively complex. The main reason is that when the semi-finished component sidewall is extruded, it is different from a normal tire. After the white sidewall appearance font is polished, the presented font is white. Therefore, white glue needs to be used instead of black glue during extrusion, but it is not entirely white around the circumference, only white in the protruding font part. In this way, a layer of black film needs to be laminated on the white glue. After vulcanization, the black glue covering the protruding font part is polished off, and finally, a white font will be presented. Currently, ordinary sidewall films are all produced by a three-layer composite extruder. There are only 3 types of sidewall rubber itself, but 4 types of rubber are required for the white sidewall film, so an additional layer of film is needed. Also, due to the limitation of the screw size arrangement relationship of the extruder, the white glue can only be extruded on the upper side, while the film of the existing two-roll calender in the production line is on the lower side. Therefore, it is impossible to hot paste the black cover film online and can only be solved by cold pasting in the molding process stage. This leads to an increase in the step of cold pasting the film in the molding process, reducing the efficiency of the molding process and being not conducive to improving the quality of the tire. Summary of the Invention

[0003] The purpose of the utility model is to provide a sidewall turning device for changing the cold pasting of a white sidewall cover film to online hot pasting, which can cancel the step of cold pasting the film in the molding process, improve the efficiency of the molding process, and is conducive to improving the quality of the tire.

[0004] The technical solution of the utility model is: it includes a mounting frame, on which a horizontal long shaft is provided. At least three drive roll assemblies are axially spaced apart and installed on the horizontal long shaft. Each drive roll assembly is respectively composed of a connecting block one, a vertical shaft, a connecting block two, a horizontal shaft, and a drive roll. The connecting block one of each drive roll assembly is installed on the horizontal long shaft, the vertical shaft is installed on the connecting block one with an adjustable position up and down, the connecting block two is installed on the vertical shaft, the horizontal shaft is installed on the connecting block two with an adjustable position horizontally, and one end of the drive roll rotating shaft is connected to one end of the horizontal shaft, and the axial angle of the drive roll with the horizontal plane can be adjusted.

[0005] The technical effect of the utility model is: it can turn the sidewall during the process of driving the sidewall, change the up and down direction of the sidewall, so as to achieve the purpose of using a two-roll calender to hot paste the cover film online. Thus, the step of cold pasting the cover film in the molding process can be cancelled, the efficiency of the molding process is improved, and it is conducive to improving the quality of the tire. Changing the cold pasting of the film in the molding process to online hot pasting for the white sidewall production can also reduce the usage of PE paper and lower the production cost.

[0008] On the body of the connecting block one 31, a long shaft hole is provided in the horizontal direction and a vertical shaft hole is provided in the vertical direction. On one side of the body of the connecting block one 31 where the long shaft hole is provided and on one side where the vertical shaft hole is provided, elastic slits 36 extending from the shaft hole to the outside of the body are respectively provided. On both sides of each elastic slit 36 on the body, a bolt hole and a threaded hole are provided. A bolt 4 passing through the bolt hole and connected to the threaded hole is provided in the bolt hole and the threaded hole, so that the connecting block one 31 is respectively clamped on the horizontal long shaft 2 and the vertical shaft 32.

[0009] On the body of the connecting block two 33, a horizontal shaft hole is provided in the horizontal direction and a vertical shaft hole is provided in the vertical direction. On one side of the body of the connecting block two 33 where the horizontal shaft hole is provided and on one side where the vertical shaft hole is provided, elastic slits 36 extending from the shaft hole to the outside of the body are respectively provided. On both sides of each elastic slit 36 on the body, a bolt hole and a threaded hole are provided. A bolt 4 passing through the bolt hole and connected to the threaded hole is provided in the bolt hole and the threaded hole, so that the connecting block two 33 is respectively clamped on the horizontal shaft 34 and the vertical shaft 32.

[0010] One end of the horizontal shaft 34 connected to the rotating shaft of the drive roller 35 is provided with a bolt hole, and one end of the rotating shaft of the drive roller 35 connected to the horizontal shaft 34 is provided with a threaded hole. The horizontal shaft 34 and the rotating shaft of the drive roller 35 are connected by a bolt 4 passing through the bolt hole and matching with the threaded hole, and the angle between the axis of the drive roller 35 and the axis of the horizontal shaft 34 can be adjusted.

[0011] Each bolt 4 is respectively an internal hexagonal bolt equipped with a flat washer and a spring washer.

[0012] The mounting frame 1 is composed of a column 11, a cross beam 12 and a longitudinal beam 13. The cross beam 12 extends in the horizontal direction, one end is vertically connected to the upper end of the column 11 horizontally, and the other end is vertically connected to the middle of the longitudinal beam 13 extending in the horizontal direction horizontally.

[0013] The column 11, the cross beam 12 and the longitudinal beam 13 are respectively square steel pipes.

[0014] The cross-sections of the horizontal long shaft 2, the vertical shaft 32, and the horizontal shaft 34 are all circular, enabling the first connecting block 31 and the second connecting block 33 to adjust their positions axially and circumferentially on each shaft, so as to adjust the height, position, and axis of each driving roller 35, making them cooperate with each other and facilitating the smooth flipping and conveying of the tire sidewall more easily.

[0015] The horizontal long shaft 2 is installed on the mounting frame 1 through the first connecting block 31 of the driving roller assembly 3 located at both ends of the longitudinal beam 13 respectively. The mounting frame 1 is installed on the roller bed frame of the tire production line and can be adjusted in height up and down.

[0016] Each driving roller 35 can adjust its height and tilt angle to meet the needs of flipping the tire sidewall.

[0017] Three driving roller assemblies 3 are axially spaced apart and installed on the horizontal long shaft 2. The driving rollers 35 on the three driving roller assemblies 3 are, in sequence from the tire-side inlet end to the tire-side outlet end, the pre-flipping roller, the flipping roller, and the height-limiting roller.

[0018] Or four driving roller assemblies 3 are axially spaced apart and installed on the horizontal long shaft 2. The driving rollers 35 on the four driving roller assemblies 3 are, in sequence from the tire-side inlet end to the tire-side outlet end, the pre-flipping roller, the protection roller, the flipping roller, and the height-limiting roller.

[0019] The function of the pre-flipping roller is to lift the tire sidewall away from the roller bed. The pre-flipping roller needs to be adjusted to an appropriate height and angle to make the tire sidewall in an inclined state, so as to facilitate the next step of flipping the tire sidewall.

[0020] The function of the flipping roller is to convey the flipped tire sidewall, and it also needs to be adjusted to an appropriate height and angle to facilitate the smooth conveyance of the inclined tire sidewall after flipping.

[0021] The height-limiting roller is located above the tire sidewall. Its function is to press down the flipped tire sidewall and make the tire sidewall return to a horizontal state, so as to cooperate with the conveying rollers on the subsequent production line. Its height is lower than that of the flipping roller and its axis is along the horizontal direction.

[0022] The protection roller is located above the tire sidewall. Its axis is inclined to the horizontal direction. Its function is to press down the tire sidewall being flipped, preventing the large-sized tire sidewall that is not easily flipped from turning back to its original state, so as to ensure the success of flipping and play a protective role.
