[0047] In order to achieve the purpose of controlling the work of the fixing assembly, the device adopts the following technical scheme: the connecting assembly comprises a threaded rod 26, the threaded rod 26 is connected inside the rack 1, a threaded block 27 is sleeved outside the threaded rod 26, the threaded block 27 is connected with the threaded rod 26 through threads, an L-shaped rod 28 is fixedly connected to one side of the threaded block 27, a through groove is formed in the top of the rack 1, the L-shaped rod 28 penetrates through the through groove, a rotating shaft 29 is embedded on the adapter block 2, the rotating shaft 29 is hollow, a bevel gear 30 is fixedly connected to one end of the rotating shaft 29, a bevel gear 31 is arranged on one side of the bevel gear 30 in meshing connection, the bevel gear 31 is fixedly sleeved outside the threaded rod 26, the threaded rod 26 is connected with the rack 1 through bearings, the rotating shaft 29 is connected with the adapter block 2 through bearings, a spiral groove 32 is formed in the inner wall of the rotating shaft 29, a moving rod 33 is fixedly connected to one side of the moving frame 7, the moving rod 33 penetrates through the vertical rod 9 and is in sliding contact with the vertical rod 9, one end of the moving rod 33 extends into the rotating shaft 29, a protruding block 34 is fixedly connected to the bottom of the moving rod 33, the protruding block 34 is slidably embedded in the spiral groove 32, a positioning rod 35 is fixedly connected to the inner wall of the top of the rack 1, the positioning rod 35 penetrates through the threaded block 27 and is in sliding contact with the threaded block 27.

[0048] In order to achieve the purpose of reducing wear, the rotating block 3 is connected with the rack 1 and the adapter block 2 through bearings.

[0049] The use process of the present application is as follows: as shown in Figure 1 and 2 When cutting the lamp strip body 6, the motor 10 is controlled to rotate forward, and the rotation of the motor 10 drives the rotation of the rotating shaft 11. Since the bevel gear 12 and the reciprocating screw rod 14 are connected with the rotating shaft 11 through the one-way bearing, the reciprocating screw rod 14 rotates when the motor 10 rotates forward, and the bevel gear 12 does not rotate. The rotation of the reciprocating screw rod 14 drives the sliding seat 15 to move leftward and then rightward, so that the sliding seat 15 moves leftward and rightward for one round trip. The movement of the sliding seat 15 drives the movement of the moving frame 7, and the moving frame 8 moves leftward and rightward for one round trip. When the moving frame 8 moves, the cutting machine 8 is controlled to work, so that the blade of the cutting machine 8 rotates and cuts the right lamp strip body 6. Since the cutting groove 1, the cutting groove 2 and the cutting groove 3 are aligned, the cutting work can be carried out normally.

[0050] After cutting, the motor 10 is controlled to rotate reversely, so that the bevel gear 12 rotates, and the reciprocating screw rod 14 does not rotate. The rotation of the bevel gear 12 drives the rotation of the bevel gear 13, and the rotation of the bevel gear 13 drives the rotation of the rotating block 3. The rotating block 3 is controlled to rotate by the motor 10 for half a circle, so that the two lamp strip bodies 6 are exchanged, and the same principle is used to control the motor 10 to rotate forward again to carry out the cutting work.

[0051] When the workbench 4 rotates, the two fixed components also rotate, so that the L-shaped rod 28 can be clamped in the grooves on the two pull rods 22 in turn. When the moving frame 7 moves leftward, the moving rod 33 and the protrusion 34 also move leftward. Since the protrusion 34 is embedded in the spiral groove 32, the protrusion 34 moves leftward to drive the rotation of the rotating shaft 29 and the bevel gear 30. The rotation of the bevel gear 30 drives the rotation of the bevel gear 31, and the rotation of the bevel gear 31 drives the rotation of the threaded rod 26. The rotation of the threaded rod 26 drives the downward movement of the threaded block 27 and the L-shaped rod 28, so that the left pull rod 22 and the toothed plate 23 are pulled downward, and the first gear 36 on the left side rotates, so that the rotating shaft 18, the rotating rod 19 and the clamping plate 20 on the left side rotate, and the two torsional springs 25 on the left side are elastically deformed. In this way, the clamping plate 20 on the left side and the placing block 5 are in an open state, and the lamp strip body 6 after cutting can be taken out manually, and a new lamp strip body 6 can be placed. In this way, the device can cut and replace the new lamp strip body 6 at the same time.

[0052] When the cutting machine 8 moves right to reset after cutting, the pull rod 22 and the protrusion 34 also move right, so that the rotating shaft three 29, the bevel gear three 30, the bevel gear four 31, the threaded rod 26 and other components are reversed, then the threaded block 27 and the L-shaped rod 28 move upward, so that the pulling force on the pull rod 22 is released, and then the clamping plate 20 can reset to clamp and fix the new lamp strip body 6, and the automatic clamping and fixing and releasing work is synchronized with the cutting work, so that the cutting efficiency is increased, and more time is not wasted.

[0053] The above is only the preferred embodiment of the present application, and any skilled person in the art can modify the present application by using the technical solutions described above or modify it into equivalent technical solutions. Therefore, any simple modification or equivalent replacement according to the technical solutions of the present application is within the scope of protection of the present application.
