Description

Technical Field

[0001] The utility model relates to the technical field of tire production, in particular to a tire calendering mechanism for a dump truck. Background Art

[0002] During tire production, extruded rubber sheets need to be passed through a calender to be pressed into a certain thickness. Prior art utility model patent application number 202420314048.9 discloses a tire calendering mechanism, which primarily comprises an extrusion mechanism, a rotating shaft, and two sets of cutting blades, both fixedly mounted on the rotating shaft. During use, the rubber sheet is calendered by the extrusion mechanism, then passed through the two sets of cutting blades, which are then rotated by the rotating shaft. During rotation, the two sets of cutting blades cut the rubber sheet into the desired width. The inventors believe that this mechanism presents the following problems during use: Because the two sets of cutting blades are immovable on the rotating shaft, they can only cut the rubber sheet into the desired width and cannot be cut into different widths according to the tire model, making it inconvenient to use and highly limited. Utility Model Content

The winding mechanism is located on the right side of the fixed shaft and has a winding function. When calendering the rubber sheet, the heated rubber sheet is first passed through the extrusion mechanism. The rubber sheet is squeezed into a suitable thickness through the extrusion mechanism, and then the rubber sheet is cooled by the cooling mechanism to shape the rubber sheet. After that, the rubber sheet passes through the two sets of cutting blades, and the driving mechanism is turned on at the same time. The driving mechanism causes the fixed shaft to drive the two sets of cutting blades to rotate at high speed through the connecting shaft.

[0019] Example 1

[0020] like Figures 1 to 5The tire calendering mechanism of a dump truck of the present invention includes a base plate 1 and two groups of cutting blades 2, an extrusion mechanism, a cooling mechanism, two groups of connecting shafts 3, a fixed shaft 4, a driving mechanism, two groups of connecting mechanisms and a winding mechanism. The extrusion mechanism is installed on the base plate 1, and the extrusion mechanism has an extrusion function. The cooling mechanism is located on the right side of the extrusion mechanism, and the cooling mechanism has a cooling function. The two groups of cutting blades 2 are respectively fixedly installed on the fixed shaft 4 through two groups of connecting mechanisms. The connecting mechanism has a detachable and movable function. The two groups of connecting shafts 3 are respectively fixedly installed on the front and rear parts of the fixed shaft 4. The driving mechanism is used to drive the connecting shaft 3 to rotate. The winding mechanism is located on the right side of the fixed shaft 4, and the winding mechanism has a winding function. When calendering the rubber sheet 25, the heated rubber sheet 25 is first passed through the extrusion mechanism and then passed through the extrusion mechanism. The rubber sheet 25 is squeezed to a suitable thickness, and then the rubber sheet 25 is cooled by a cooling mechanism to shape the rubber sheet 25. After that, the rubber sheet 25 passes through the two sets of cutting blades 2, and the driving mechanism is turned on at the same time. The driving mechanism causes the fixed shaft 4 to drive the two sets of cutting blades 2 to rotate at high speed through the connecting shaft 3. When the rubber sheet 25 passes through the two rotating sets of cutting blades 2, the two rotating sets of cutting blades 2 cut the rubber sheet 25 into a suitable width, and then the winding mechanism winds up the cut rubber sheet 25. Since the two sets of cutting blades 2 are installed on the fixed shaft 4 through the connecting mechanism, and the connecting mechanism can be disassembled and moved, the staff can adjust the distance between the two sets of cutting blades 2 on the fixed shaft 4 according to the needs of tire production, and can cut out rubber sheets 25 of different widths. It is easy to use, has low limitations, and is highly practical.

[0021] like Figure 1 and Figure 5 The driving mechanism includes a vertical plate 5 and a driving motor 6. The vertical plate 5 is fixedly mounted on the upper end of the base plate 1, and the connecting shaft 3 is rotatably mounted on the vertical plate 5. The driving motor 6 is fixedly mounted on the vertical plate 5, and the output end of the driving motor 6 is connected to the connecting shaft 3. When the rubber sheet 25 is cut, the driving motor 6 is turned on, and the driving motor 6 drives the fixed shaft 4 to drive the two sets of cutting blades 2 to rotate at high speed through the connecting shaft 3. When the rubber sheet 25 passes through the two sets of cutting blades 2 rotating at high speed, the two sets of cutting blades 2 rotating at high speed will cut the rubber sheet 25 into a suitable width, which facilitates the cutting of the rubber sheet 25.

[0022] like Figure 5The connecting mechanism includes a mounting block 7, and a plurality of threaded holes 8 are provided on the fixed shaft 4. The mounting block 7 is fixedly connected to the cutting blade 2, and the mounting block 7 is fixedly mounted on the fixed shaft 4 by a bolt, and the bolt is threadedly connected to one of the threaded holes 8; when adjusting the installation position of the cutting blade 2 on the fixed shaft 4, the cutting blade 2 is moved to a suitable position on the fixed shaft 4, and then the bolt is passed through the mounting block 7 and fixedly screwed with one of the threaded holes 8 on the fixed shaft 4, so that the cutting blade 2 is fixedly mounted on the fixed shaft 4; it is convenient to adjust the installation position of the cutting blade 2, and rubber sheets 25 of different widths can be cut.

The upper end of the push rod 15 is connected to the output end of the hydraulic cylinder 14, and the hydraulic cylinder 14 is fixedly mounted on the hanging frame 13; the hanging frame 13 is fixedly hoisted on the bracket of the workshop. When the rubber sheet 25 is rolled, the rubber sheet 25 passes between the upper pressing roller 11 and the lower pressing roller 10, and the hydraulic cylinder 14 is opened. The hydraulic cylinder 14 drives the upper pressing roller 11 to descend through the push rod 15, so that the rubber sheet 25 is squeezed by the upper pressing roller 11 and the lower pressing roller 10 when passing through the lower pressing roller 10, and the rubber sheet 25 is squeezed to a suitable thickness, thereby improving reliability.

[0024] like Figure 1 and Figure 4The cooling mechanism includes a fixed frame 17, a lower air blowing pipe 18, an upper air blowing pipe 19, an air delivery pipe 20 and an air cooler 21.

When the rubber sheet 25 passes between the upper blowing pipe 19 and the lower blowing pipe 18, the air cooler 21 is turned on to allow cold air to enter the upper blowing pipe 19 and the lower blowing pipe 18 through the air supply pipe 20. Then, the cold air is blown to the upper and lower ends of the rubber sheet 25 through the upper blowing pipe 19 and the lower blowing pipe 18, uniformly cooling the upper and lower ends of the rubber sheet 25, so that the rubber sheet 25 is shaped; this facilitates the cooling of the rubber sheet 25.

The support plate 22 is fixedly mounted on the upper end of the base plate 1, the servo motor 23 is fixedly mounted on the support plate 22, and the winding roller 24 is rotatably mounted on the support plate 22. The input end of the winding roller 24 is connected to the output end of the servo motor 23; when the rubber sheet 25 is wound, the rubber sheet 25 is wound around the winding roller 24, and then the servo motor 23 is turned on, and the servo motor 23 drives the winding roller 24 to rotate. The rotating winding roller 24 allows the rubber sheet 25 to be wound on the winding roller 24; this facilitates the winding of the rubber sheet 25.
