[0038] The technical solution of the present invention is further described in detail below through specific embodiments and in conjunction with the accompanying drawings:

[0039] Example 1: Reference Figures 1 to 4 As shown, a synchronous cutting bed bristle bed driving device includes a rotating shaft 1 and a driving motor 2. A driven wheel 11 is provided on the rotating shaft 1, an output shaft 21 is provided on the driving motor 2, and a driving wheel 22 is fixedly provided on the output shaft 21. The output shaft 21 of the driving motor 2 is arranged parallel to the rotating shaft 1, and a transmission belt 3 is connected between the driving wheel 22 and the driven wheel 11.

[0040] The driving wheel 22 in this embodiment is a driving sprocket, the driven wheel 11 is a driven sprocket, and the transmission belt 3 is a chain, and the driving wheel 22 and the driven wheel 11 are driven by the chain. Through the transmission of the chain and sprocket, the power transmission efficiency between the output shaft 21 and the rotating shaft 1 can be better.

[0041] At the same time, a suspension tensioning device 3 is provided in this embodiment, and the suspension tensioning device 3 includes a mounting plate 31 fixedly connected to the drive motor 2 and a fixed plate 32 connected to the mounting plate 31; the mounting plate 31 is arranged at an angle, and a rotating pin 311 is provided at one end of the mounting plate 31; the other end of the mounting plate 31 is connected to the fixed plate 32.

[0042] Specifically, a rotation pin 311 is provided at the bottom end of the mounting plate 31. In this embodiment, the fixing plate 32 is an I-beam, with a pad 324 provided at the bottom end of the I-beam. The retaining slot 321 is provided on the pad 324. The rotation pin 311 is disposed within the retaining slot 321. A mounting hole 312 is provided at the top end of the mounting plate 31. A protruding plate 323 is provided at the top end of the I-beam, with the fixing hole 322 provided on the protruding plate 323. Bolts 33 pass through the fixing hole 322 and the mounting hole 312, thereby connecting the mounting plate 31 and the fixing plate 32.

[0043] Specifically, a limit plate 325 is provided on the cushion block 324, and a fixing slot 326 is provided on the limit plate 325, which cooperates with the limit slot 321. The limit plate 325 and cushion block 324 are connected by bolts, so that the fixing slot 326 cooperates with the limit slot 321 to form a limit hole, and the rotation pin 311 is disposed in the limit hole. The cooperation between the fixing slot 326 and the limit slot 321 can limit the rotation pin 311, so that the rotation pin 311 can only rotate within the limit hole.

[0044] The working principle of this embodiment is as follows: the driving device is arranged in the cutting table frame 4, and the transmission shaft 1 is provided at both ends of the cutting table frame 4 in the longitudinal direction. The transmission shaft 1 at one end is connected to the driving motor 2 through a transmission belt 3. The driving motor 1 is arranged inside the cutting table frame 4, so that the driving motor 2 can be placed inside the cutting table frame 4, so that the overall structure of the cutting table can be more compact, and the space required for installing the cutting table can be smaller; at the same time, since the driving device is arranged inside the cutting table frame, it can effectively prevent the occurrence of danger.

[0045] At the same time, a self-suspension device 3 is provided, and the working principle of the self-suspension device 3 is as follows: the mounting plate 31 is set to be tilted, and through the action of the self-weight of the driving motor 1 and the tension of the transmission belt 3, the mounting plate 31 is made to rotate with the rotating pin 311 as the center of rotation, and the mounting plate 31 has a tendency to tilt in the tilted direction, and the upper end of the mounting plate 31 is connected to the fixed plate 32 by a bolt 33, so that the mounting plate 31 is tightened by the bolt 33, thereby making the transmission belt 3 between the driving wheel 22 and the driven wheel 11 have a tension, which produces a tensioning effect on the transmission belt 3, thereby achieving a tensioning effect on the transmission belt 3; therefore, in the present invention, the tensioning force of the transmission belt 3 can be adjusted by adjusting the tension between the fixed plate 32 and the mounting plate 31 by adjusting the bolt 33; the installation of other tensioning devices is omitted, making the structure of the cutting table more compact.

[0046] Example 2: Reference Figures 1 to 5 As shown, this embodiment is similar in structure to embodiment 1, except that a first gasket 34 is provided on the side with the same inclination direction as the mounting plate 31 , and a buffer spring 35 is provided between the first gasket 34 and the mounting plate 31 .

[0047] The output shaft 21 is provided with a self-tensioning device 6 .

[0048] Specifically, the self-tensioning device 6 includes a rotating disk 61 sleeved on the output shaft 21 and a tensioning cable 62 connecting the rotating disk 61 and the mounting plate 31; there is no power transmission between the rotating disk 61 and the output shaft 21, and the two can rotate with each other. A friction bent plate 63 is provided on the end surface of the rotating disk 61, and a rotating hole 631 is provided at one end of the friction bent plate 63. A fixed shaft 612 is provided on the rotating disk 61, and the rotating hole 631 cooperates with the fixed shaft 612 so that the friction bent plate 63 can rotate around the fixed shaft 612, and the other end of the friction bent plate 63 is connected to the tensioning cable 62; a convex wall 611 is provided in the outer circumferential direction of the end surface of the rotating disk 61, and an abutment spring 64 is provided between the convex wall 611 and the friction bent plate 63, one end of the abutment spring 64 abuts against the convex wall 611, and the other end of the abutment spring 64 abuts against one end of the friction bent plate 63 close to the tensioning cable 62.

[0049] A first guide wheel 65 is provided on the fixed plate 32, and a second guide wheel 66 is provided on the rotating disk 61. The first guide wheel 65 and the second guide wheel 66 can rotate freely. After the tensioning cable 62 is connected to the friction bent plate 63, it passes around the second guide wheel 66 and the first guide wheel 65 in turn and is connected to the end of the mounting plate 31 close to the bolt 33.

[0050] The friction bent piece 63 is in an arc shape that cooperates with the output shaft 21. The arc-shaped friction bent piece 63 can better fit the surface of the output shaft 21, so that the friction bent piece 63 and the output shaft 21 can better contact each other.

[0051] In this embodiment, after long-term use, the transmission belt 3 will be continuously stretched, so that the tension of the transmission belt 3 will continue to decrease, thereby making the power transmitted by the transmission belt 3 unstable. Therefore, a self-tensioning device 6 is provided. The specific working principle of the self-tensioning device 6 is as follows: Figure 5 As shown, under the normal tension of the transmission belt 3, the tensioning cable 62 has a certain tension, and the tensioning force of the tensioning cable 62 on the friction bent plate 63 and the pushing force of the abutting spring 64 on the friction bent plate 63 are balanced with each other, so that the friction bent plate 63 has no contact with the outer surface of the output shaft 21, and there is no friction between the output shaft 21 and the friction bent plate 43; when the tension of the transmission belt 3 is reduced, the transmission belt 3 is stretched, and then the buffer spring 35 acts on the mounting plate 31, so that the mounting plate 31 rotates rightward around the rotating pin 311, so that the tension on the tensioning cable 62 is reduced, thereby reducing the tension of the tensioning cable 62 on the friction bent plate 63, so that the force of the abutting spring 64 on the friction bent plate 63 is greater than the force of the tensioning cable 62 on the friction bent plate 63, and the abutting spring 64 pushes the friction bent plate 63 to contact with the output shaft 21, so that friction is generated between the output shaft 21 and the friction bent plate 63. Under the action of friction, the output shaft 21 belt The movable friction bent plate 63 rotates, thereby causing the friction bent plate 63 to drive the rotating disk 61 to rotate. The rotation of the rotating disk 61 drives the tensioning cable 62 to rotate, causing the tensioning cable 62 to be wound around the circumferential side wall of the rotating disk 61, thereby reducing the length of the tensioning cable 62, thereby increasing the tension of the tensioning cable 62 on the mounting plate 311, and since the tensioning cable 62 is connected to the end of the mounting plate 21 close to the bolt 33, the mounting plate 31 rotates around the rotating pin 311, thereby increasing the tension on the transmission belt 3; when the tension of the tensioning cable 62 on the friction bent plate 63 and the thrust of the abutting spring 64 on the friction bent plate 63 are re-balanced with each other, the friction bent plate 63 is separated from the output shaft 21, and there is no power transmission between the friction bent plate 63 and the output shaft 21, causing the rotating disk 61 and the output shaft 21 to rotate relative to each other, thereby realizing the function of automatically adjusting the tension of the transmission belt 3.
