DETAILED DESCRIPTION

[0023] The technical solution of the present utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0024] like Figures 1 to 5 As shown, the embodiment of the utility model provides a coated abrasive tool bending device, which is used to perform bending treatment on the coated abrasive tool that becomes brittle after curing treatment, so as to ensure that the flexibility of the coated abrasive tool meets the use requirements.

[0025] Please refer to Figure 1 and Figure 2The coated abrasive bending device comprises an unwinding component 1 and a winding component 2. The unwinding component 1 is used to unwind the coated abrasive to be bent and input the coated abrasive into the coated abrasive bending device.

When the unwinding component 1 unwinds the coated abrasive, the winding component 2 winds up and pulls the coated abrasive to move on the coated abrasive bending device. The coated abrasive tool kneading device also includes three linear kneading assemblies 3 arranged at intervals between the unwinding assembly 1 and the winding assembly 2, the linear kneading assemblies 3 respectively including a frame 31, a kneading roller 32 rotatably arranged on the frame 31, and a first driving assembly 33 transmission-connected to the kneading roller 32, the axial direction of the kneading roller 32 in the linear kneading assembly 3 close to the unwinding assembly 1 is parallel to the axial direction of the kneading roller 32 in the linear kneading assembly 3 close to the winding assembly 2, and the axial direction of the kneading roller 32 in the linear kneading assembly 3 located in the middle is parallel to the axial direction of the kneading roller 32 in the linear kneading assembly 3 located on both sides. 2, that is, the three kneading rollers 32 in the three linear kneading assemblies 3 are arranged in a U shape, and an oblique kneading assembly 4 is further provided between any two adjacent linear kneading assemblies 3, the oblique kneading assembly 4 comprises a mounting frame 41, and the opposite ends of the mounting frame 41 respectively correspond to the frames 31 in the two adjacent linear kneading assemblies 3 one by one, and a kneading strip 42 is provided on the mounting frame 41, and the angles between the length directions of the kneading strip 42 and the axial directions of the kneading rollers 32 in the two adjacent linear kneading assemblies 3 are acute angles, and the length directions of the kneading strips 42 in the two oblique kneading assemblies 4 are perpendicular to each other.

[0026] Specifically, the process of the coated abrasive kneading device provided in this embodiment for kneading the coated abrasive is as follows: the coated abrasive to be kneaded is unwound on the unwinding component 1, and then passes through the linear kneading component 3, the oblique kneading component 4, the linear kneading component 3, the oblique kneading component 4 and the linear kneading component 3 in sequence, and then enters the winding component 2 for winding; when the coated abrasive passes through each of the linear kneading components 3, the kneading roller 32 contacts the side of the coated abrasive coated with the abrasive, and the kneading roller 32 kneads the coated abrasive as the coated abrasive moves; and when the coated abrasive passes through the oblique kneading component 4, the kneading strip 42 contacts the side of the coated abrasive not coated with the abrasive The conveying direction of the coated abrasive is abutted and changed. During the conveying process of the coated abrasive, the kneading strips 42 knead the coated abrasive along a direction forming an acute angle with the axial direction of the kneading roller 32, and the length directions of the kneading strips 42 in the two oblique kneading assemblies 4 are perpendicular to each other, so that the coated abrasive is kneaded along multiple different angles during the process of the coated abrasive passing through the linear kneading assembly 3, the oblique kneading assembly 4, the linear kneading assembly 3, the oblique kneading assembly 4 and the linear kneading assembly 3 in sequence.

The two support rollers 47 are respectively located on the upper and lower sides of the kneading strip 42 and the axial direction of the support rollers 47 is parallel to the length direction of the kneading strip 42. The support rollers 47 disposed on the mounting frame 41 are used to support the coated abrasive entering the oblique conveying assembly, prevent the coated abrasive from contacting the mounting frame 41 and causing the coated abrasive to be scratched by the mounting frame 41, and guide the coated abrasive to contact the kneading strip 42, which is beneficial to improving the reliability of the coated abrasive kneading device.

[0033] like Figure 1 , Figure 3 and Figure 4 As shown, an adjustment assembly 5 is respectively provided between the linear kneading assembly 3 and the oblique kneading assembly 4, and the adjustment assembly 5 comprises an adjustment seat 51 fixedly arranged on the frame 31, an adjustment block 52 which can be lifted and lowered on the adjustment seat 51, and an adjustment roller 53 which can be rotatably arranged on the adjustment block 52, and the axial direction of the adjustment roller 53 is parallel to the axial direction of the corresponding kneading roller 32 on the frame 31.

[0035] like Figure 4As shown, the adjustment seat 51 is provided with a second threaded hole and a second adjustment screw 56 matched with the second threaded hole, the axial direction of the second threaded hole is vertical and one end of the adjustment screw is rotatably connected with the adjustment block 52. When the second adjustment screw 56 is rotated, the second adjustment screw 56 moves in the second threaded hole along the axial direction of the second threaded hole, and drives the adjustment block 52 to move synchronously with the second adjustment screw 56, so as to adjust the position of the adjustment block 52 on the adjustment seat 51, and a hand wheel 57 is provided at one end of the second adjustment screw 56 away from the adjustment block 52, and the second adjustment screw 56 can be conveniently rotated by operating the hand wheel 57 to adjust the position of the adjustment block 52, so as to facilitate the use of the coated abrasive tool kneading device.

When the unwinding roller 12 rotates under the drive of the second driving assembly 13, the transmission shaft 6 transmits the power output by the second driving assembly 13 to the winding roller 22 to make the winding roller 22 rotate synchronously, so that the rotation speed of the winding roller 22 is consistent with the rotation speed of the unwinding roller 12, so that the unwinding speed of the unwinding assembly 1 is the same as the winding speed of the winding assembly 2, and the coated abrasive tool is effectively prevented from being loosened when moving on the coated abrasive tool kneading device.

[0037] In detail, the second driving assembly 13 includes a second motor 14 and a second reduction box 15 which is transmission-connected to the output end of the second motor 14, and the unwinding roller 12 is transmission-connected to the second reduction box 15.
