[0025] Specifically, the operation steps of the kneading device of the kneading machine provided in the embodiment for the grinding tool are as follows: after the grinding tool to be processed passes through the gap between the kneading strip 5 and the pressing roller 6, the second driving assembly 7 is operated to drive the movable seats 61 to lift on the support seats 4 to adjust the position of the pressing roller 6, so that the grinding tool contacts the kneading strip 5 under the action of the pressing roller 6, and then the grinding tool is conveyed by unwinding and winding, and the grinding tool is kneaded by the kneading strip 5; when the angle of the grinding tool kneaded by the kneading strip 5 needs to be adjusted, the first driving assembly 3 is operated to drive the rotating frame 2 to rotate relative to the frame body 1 and drive the pressing roller 6 and the kneading strip 5 to rotate, so as to change the angle between the length direction of the kneading strip 5 and the conveying direction of the grinding tool, and then adjust the angle of the grinding tool kneaded by the kneading strip 5 and the contact area between the kneading strip 5 and the grinding tool during the kneading process, so as to adjust the flexibility of the grinding tool after the kneading process. The kneading device of the kneading machine provided in the embodiment can conveniently adjust the angle of the grinding tool for kneading, so as to adjust the flexibility of the grinding tool after the kneading process as needed, meet the production needs of the grinding tool for kneading with different needs, and the adjustment operation is simple and convenient to use.

[0026] As Figure 3As shown, the rotating frame 2 is provided with a rotating shaft 21, the frame body 1 is provided with a bearing seat 11 and the bearing seat 11 is provided with a bearing 12 matched with the rotating shaft 21. The rotating frame 2 is connected with the frame body 1 in rotation through the cooperation of the rotating shaft 21 and the bearing 12, and the rotating frame 2 can rotate smoothly relative to the frame body 1, which is beneficial to improve the structural stability of the kneading device of the kneading machine.

[0027] In detail, the first driving assembly 3 comprises a motor 31 and a first gear 32 arranged at the output end of the motor 31, and the rotating shaft 21 is sleeved with a second gear 22 matched with the first gear 32. When the first gear 32 rotates under the drive of the motor 31, the power output by the motor 31 is transmitted to the rotating frame 2 through the cooperation of the first gear 32 and the second gear 22, so that the rotating frame 2 rotates under the drive of the motor 31 and drives the kneading strip 5 to rotate, thereby adjusting the angle of the kneading strip 5 for kneading the mold.

[0028] As shown in Figure 1 and Figure 4 , the rotating frame 2 is provided with an arc-shaped groove 23 and the center of the arc-shaped groove 23 is located on the axis of the rotating shaft 21, and the frame body 1 is provided with a vertical limiting rod 13 which extends into the arc-shaped groove 23. The arc-shaped groove 23 is arranged on the rotating frame 2 and the limiting rod 13 matched with the arc-shaped groove 23 is arranged on the frame body 1. When the first driving assembly 3 drives the rotating frame 2 to rotate, the limiting rod 13 slides in the arc-shaped groove 23 to limit the rotating stroke of the rotating frame 2, preventing the angle of the rotating frame 2 from being too large to cause part of the mold to be separated from the kneading strip 5 during the kneading process.

[0029] Specifically, one end of the limiting rod 13 penetrates the arc-shaped groove 23 and the end of the limiting rod 13 penetrating the arc-shaped groove 23 has a threaded portion, the limiting rod 13 is provided with a locking nut 14 matched with the threaded portion, and the locking nut 14 abuts against one side of the rotating frame 2 away from the frame body 1. The locking nut 14 arranged on the limiting rod 13 is used to lock the position of the rotating frame 2. Before adjusting the kneading strip 5, the locking nut 14 is rotated away from the rotating frame 2, at this time the rotating frame 2 can rotate relative to the frame body 1, and after the kneading strip 5 is adjusted to the right position, the locking nut 14 is rotated to abut against the rotating frame 2. The position of the rotating frame 2 can be locked by the friction force between the locking nut 14 and the rotating frame 2, preventing the rotating frame 2 from rotating unexpectedly during the kneading process.

[0030] Please refer toFigure 2 and Figure 3 The opposite ends of the bending bar 5 are respectively provided with mounting portions 51, and the mounting portions 51 are provided with mounting holes 52. The support seat 4 is provided with first threaded holes 41 aligned with the mounting holes 52. The bending bar 5 can be fixed on the support seat 4 by connecting members such as bolts penetrating through the mounting holes 52 and cooperating with the first threaded holes 41. The two ends of the bending bar 5 are respectively provided with the mounting holes 52, which ensures the firm connection between the bending bar 5 and the support seat 4, and avoids loosening of the bending bar 5 during the bending process.

[0031] In this embodiment, the bending bar 5 is a metal piece. The bending bar 5 is made of metal, which not only meets the strength requirement of the bending bar 5, but also enhances the durability of the bending bar 5.

[0032] Please refer to Figure 2 and Figure 3 The second driving assembly 7 includes an adjusting screw 71 and a supporting spring 72. The adjusting screw 71 is vertically arranged on the support seat 4, and the support seat 4 is provided with second threaded holes cooperating with the adjusting screw 71. The adjusting screw 71 and the supporting spring 72 respectively abut against the opposite surfaces of the movable seat 61 in the vertical direction. When the position of the compression roller 6 needs to be adjusted, the adjusting screw 71 is rotated to move in the vertical direction in the second threaded hole. When the adjusting screw 71 descends in the vertical direction, the movable seat 61 descends under the pushing of the adjusting screw 71, so as to drive the compression roller 6 to descend in the vertical direction and further compress the supporting spring 72. When the adjusting screw 71 ascends in the vertical direction, the supporting spring 72 is elongated and pushes the movable seat 61 to ascend in the vertical direction, so as to keep the movable seat 61 abutting against the adjusting screw 71. The compression roller 6 is driven by the movable seat 61 to ascend in the vertical direction. That is, the position of the compression roller 6 can be conveniently adjusted by rotating the adjusting screw 71, which is simple to operate.

[0033] In detail, the support seat 4 is provided with a vertical guide rod 42, the movable seat 61 is provided with a guide hole cooperating with the guide rod 42, and the supporting spring 72 is sleeved on the guide rod 42. The guide rod 42 is used to limit the moving direction of the movable seat 61. The cooperation between the guide rod 42 and the guide hole prevents the movable seat 61 from deviating from the preset direction when moving, which ensures the stable operation of the bending machine.

[0034] As Figure 2As shown, the adjusting screw 71 is provided with an adjusting hand wheel 73, which is located at the end of the adjusting screw 71 away from the movable seat 61. The adjusting hand wheel 73 provided at the end of the adjusting screw 71 is used to operate the rotation of the adjusting screw 71. By rotating the adjusting hand wheel 73, the adjusting screw 71 can be conveniently rotated and the rotation direction of the adjusting screw 71 can be controlled, so that the position of the pressing wheel can be conveniently adjusted.

[0035] Please refer to Figure 1 In the embodiment, two kneading devices are arranged on the rack of the kneading machine at intervals, and the included angles between the kneading strips 5 and the conveying direction of the mold in the two kneading devices are different. By arranging multiple kneading devices to knead the mold from different angles, the kneading effect can be further improved, and the flexibility of the mold after the kneading treatment can meet the requirements.
