DETAILED DESCRIPTION

[0022] The utility model will be further explained in detail below in combination with the drawings.

[0023] Embodiment:

[0024] Referring to Figures 1-4 The utility model discloses a printing plate roller deformation monitoring device, including mounting frame 1 and the plate roller main body 2 of setting between its lateral wall, both lateral walls of mounting frame 1 are rotatably connected with mounting shaft 3, and the plate roller main body 2 is installed between two mounting shafts 3, and one lateral wall of mounting frame 1 is provided with laser level 7, and the surface of plate roller main body 2 is provided with color line 6.

[0025] One side of laser level 7 is provided with adjusting part, and the adjusting part includes the sliding groove 15 opened in one lateral wall of mounting frame 1, and laser level 7 is slidably connected between the side walls of sliding groove 15 through the sliding block, and the first spring 17 is fixedly connected between the sliding block and the sliding groove 15, and the upper portion of mounting frame 1 is provided with screw rod 16, and the screw rod 16 movably penetrates the inner top wall of sliding groove 15 and abuts against the upper end of sliding block.

[0026] In the embodiment, referring to Figure 1 The plate roller main body 2 can be fixed between two mounting shafts 3 through bolts, the mounting shaft 3 can be driven through a rotating motor, and the rotating motor is specifically installed in one side of mounting frame 1, the output end of the motor is connected with the mounting shaft 3 through a shaft coupling, and the mounting shaft 3 can be driven to rotate, so that printing is carried out.

[0027] When the plate roller main body 2 of different sizes is installed or replaced, the position of laser level 7 needs to be adjusted, and the specific adjustment mode is that, referring to Figure 3 and Figure 4Positioning the laser level 7, rotating the screw 16 increases the length of the screw 16 within the sliding groove 15, causing the screw 16 to slide downwards. The first spring 17 is compressed, and the screw 16 rotates in the opposite direction, causing its lower end to move upwards. Due to its elastic recovery, the first spring 17 pushes the laser level 7 upwards. The laser level 7 can be used to monitor the level of the upper part of the printing roller body 2. By observation, when the colored lines 6 on the printing roller body 2 are not aligned with the laser horizontally, the printing roller body 2 deforms. The height of the laser level 7 can be adjusted using the screw 16 and the first spring 17, allowing monitoring of printing roller bodies 2 with different diameters, making it more convenient to use.

[0028] The installation method of the laser level 7 is not shown in the figure, but the laser level 7 can be fixed to the slider with bolts, and the laser level 7 can be disassembled.

[0029] For further details, please refer to Figure 4 Two first limiting rods 18 are fixedly connected between the inner top wall and the inner bottom wall of the sliding groove 15, and the slider is slidably connected to the circumferential side of the two first limiting rods 18.

[0030] In this embodiment, the laser level 7 is fixed on the slider, and the slider moves linearly up and down on the surface of the first limiting rod 18, which can improve the movement stability of the laser level 7.

[0031] For further details, please refer to Figure 2 A detection ring 4 is slidably arranged on the upper circumferential side of the printing roller body 2. A pressure sensor 10 is installed on one side of the detection ring 4, and a lifting component is arranged above the detection ring 4 for moving the detection ring 4 up and down.

[0032] In this embodiment, the detection ring 4 moves on the surface of the printing roller body 2. If the printing roller body 2 is bent and deformed, the movement of the detection ring 4 is resisted, and the pressure sensor 10 contacts the bent part of the printing roller body 2 and generates a force, thereby achieving the purpose of detecting whether the printing roller body 2 is deformed.

[0033] Preferably, the pressure sensor 10 is electrically connected to an external power source. Although not shown in the figure, an alarm can also be installed on the mounting bracket 1. Both the pressure sensor 10 and the alarm are connected to the signal of an external PCL controller. When the pressure sensor 10 detects a pressure signal, the alarm will issue a warning.

A traction rope 23 is fixedly connected to the other side of the movable block 20, and the traction rope 23 moves through one side of the mounting frame 1. The movable block 20 is connected to the lifting component.

[0035] In this embodiment, referring to Figure 3, pulling the traction rope 23 causes the moving block 20 to move, and the second spring 21 is in a stretched state. The moving block 20 drives the detection ring 4 to move through the lifting component and the connecting component. When the traction rope 23 is released, the second spring 21 can pull the moving block 20 back to its original position due to its own elastic recovery, so that the detection ring 4 can move back and forth.

[0036] For further details, please refer to Figure 3 The lifting component includes a hydraulic cylinder 5 fixedly connected to the lower end of the moving block 20, and the output end of the hydraulic cylinder 5 is connected to the detection ring 4 through a connector.

[0037] In this embodiment, reference Figure 3 When the moving block 20 moves, the hydraulic cylinder 5 can be driven to move. The hydraulic cylinder 5 is used in the following way: when the hydraulic cylinder 5 is started, the hydraulic cylinder 5 can drive the detection ring 4 to move up and down through the connecting parts to prevent the detection ring 4 from affecting the printing operation of the printing roller body 2.

[0038] For further details, please refer to Figure 2 The connecting component includes a connecting block 12 fixedly connected to the output end of the hydraulic cylinder 5, a connecting frame 11 fixedly connected to the upper end of the detection ring 4, the connecting block 12 inserted into the connecting frame 11, a connecting bolt 13 provided on one side of the connecting frame 11, and the connecting bolt 13 movably passes through both sides of the connecting frame 11 and the connecting block 12, and a nut 14 is threadedly connected to the circumferential side of the connecting bolt 13.

[0039] In this embodiment, reference Figure 2 The connecting block 12 and the connecting frame 11 are connected in a way that the size of the connecting block 12 is the same as the size of the slot on the connecting frame 11. The connecting bolt 13 passes through the connecting frame 11 and the connecting block 12, and the nut 14 is threaded inside the connecting bolt 13, thereby fixing the connecting frame 11 and the connecting block 12.

[0040] For further details, please refer to Figure 1 An electric drum 8 is installed on one side of the mounting frame 1. The traction rope 23 is connected to the electric drum 8. Two second limit rods 22 are fixedly connected between the side walls of the moving groove 19. The moving block 20 is slidably connected to the circumferential side of the two second limit rods 22.

[0041] In this embodiment, reference Figure 1The electric drum 8 consists of a base, a winding motor and a drum. The base is fixed on one side of the mounting frame 1, the winding motor is fixed on one side of the base, and the drum is rotatably connected to the other side of the base. The output end of the winding motor is connected to the drum through a coupling, and the traction rope 23 is fixed on the circumferential side of the drum.

[0042] The electric drum 8 is used as follows: when the winding motor is started, the output end of the winding motor drives the drum to rotate, and the traction rope 23 is wound on the surface of the drum. When the output end of the winding motor rotates in the opposite direction, the traction rope 23 is removed from the surface of the drum.

[0043] The implementation principle of the above embodiment is as follows: When the printing roller body 2 of different sizes is replaced, the screw 16 is rotated, and the length of the screw 16 in the sliding groove 15 becomes longer. The screw 16 pushes the sliding groove downward, and the first spring 17 is in a compressed state. The screw 16 rotates in the opposite direction, and the lower end of the screw 16 moves upward. The first spring 17 pushes the laser level 7 upward due to its own elastic recovery. The laser level 7 can be used to monitor the level of the upper part of the printing roller body 2. By observation, when the colored lines 6 on the printing roller body 2 are not aligned with the laser horizontally, the printing roller body 2 is deformed. The height of the laser level 7 can be adjusted by the screw 16 and the first spring 17, which can monitor printing roller bodies 2 of different diameters, making it more convenient to use.
