[0030] like Figure 1 and Figure 2As shown, the carbon block slotting deviation detection device for a sawing machine of this utility model includes a first detection unit 1, a control unit 2 electrically connected to the first detection unit 1, an alarm unit 3 electrically connected to the control unit 2, and an auxiliary unit 4 electrically connected to the control unit 2. The first detection unit 1 is installed on one side of the roller conveyor and includes a proximity switch 11 and a laser displacement sensor 12. The first detection unit 1 is installed on one side of the roller conveyor via a bracket assembly 10, and the proximity switch 11 and the laser displacement sensor 12 are respectively installed on the bracket assembly 10. Preferably, the proximity switch 11 is located below the laser displacement sensor 12. The control unit 2 is installed adjacent to the first detection unit 1 on one side of the roller conveyor and includes a housing, and a power supply 21, a first relay 22, and a second relay 23 installed in the housing. The power supply 21 supplies power to the various components. The first relay 22 receives the trigger signal from the proximity switch 11 and controls the working time of the laser displacement sensor 12. Preferably, the first relay 22 is a time relay. The second relay 23 receives the output signal from the laser displacement sensor 12 and can trigger the alarm unit 3. Alarm unit 3 includes an audible and visual alarm light 31 mounted on the housing, and a normally closed reset button mounted on the panel of the housing. The audible and visual alarm light 31 is electrically connected to a second relay 23. When the detected carbon block does not meet the requirements, the second relay 23 controls the audible and visual alarm light 31 to activate, alerting the operator to the presence of a non-compliant carbon block. The normally closed reset button allows the operator to manually reset the alarm state. Auxiliary unit 4 includes a nozzle 41 mounted on the support assembly 10, and a compressed air pipeline 42 connected to the nozzle 41 and supplying gas from the air source to the nozzle 41. The nozzle 41 is mounted on the support assembly 10 adjacent to the laser displacement sensor 12. Preferably, the nozzle 41 is equipped with a solenoid valve. Under the control of the control unit 2, the nozzle 41 periodically blows air into the lens of the laser displacement sensor 12 of the first detection unit 1 to prevent dust accumulation on the lens surface and prevent dust accumulation from affecting the detection effect. In addition, to further improve detection accuracy and adaptability, the carbon block slotting deviation detection device for the saw also includes a second detection unit. The second detection unit is mounted on the opposite side of the roller conveyor, opposite to the first detection unit 1. It detects the slotted positions at the head and tail of the carbon block to identify internal cutting deviations. It supports multi-sensor arrangement, has strong scalability, and can adapt to various offset detection needs. The second detection unit has the same structure as the first detection unit 1. The second detection unit is mounted on the roller conveyor via a bracket assembly and includes a proximity switch and a laser displacement sensor mounted on the bracket assembly.

[0031] like Figure 2 As shown, the support assembly 10 can mount the corresponding detection unit on the frame 100 of the roller conveyor. The support assembly 10 includes a support 101, an adjusting member 102, a supporting member 103, and an elastic member 104. (See also...) Figures 2 to 5The bracket 101 is generally U-shaped and includes a first branch 1011, a second branch 1015 opposite to the first branch 1011, and a vertical portion 1016 connecting the first branch 1011 and the second branch 1015. A guide rail 1012 is provided on the side of the vertical portion 1016 facing the first branch 1011 and the second branch 1015. Preferably, the guide rail 1012 has a trapezoidal cross-section, and the dimension of the end of the guide rail 1012 adjacent to the vertical portion 1016 is smaller than the dimension of the end of the guide rail 1012 away from the vertical portion 1016. An adjusting member 102 is mounted on the first branch 1011 and partially engaged with the guide rail 1012; a support member 103 is mounted on the second branch 1015 and partially engaged with the guide rail 1012. A first mounting hole 1013 is provided on the first branch 1011, and the adjusting member 102 is mounted in the first mounting hole 1013. The second support 1015 has a second mounting hole 1014, through which the support member 103 is movably inserted. The inner side of the first mounting hole 1013 is threaded. The adjusting member 102 includes an adjusting column 1021 mounted in the first mounting hole 1013, a rotating part 1022 mounted on one axial end of the adjusting column 1021, and a first clamping member 1023 mounted on the other axial end of the adjusting column 1021. Preferably, the outer side of the adjusting column 1021 has an external thread that engages with the threaded part on the inner side of the first mounting hole 1013. When the rotating part 1022 is rotated, it drives the adjusting column 1021 to rotate. With the cooperation of the two threads, the adjusting member 102 can move up and down relative to the bracket 101 to accommodate carbon blocks of different sizes. The diameter of the rotating part 1022 is larger than the diameter of the adjusting column 1021. Preferably, the outer side of the rotating part 1022 has a pattern.

[0032] The adjusting post 1021 has a flange 211 at one end adjacent to the first clamping member 1023, which extends radially outward along the adjusting post 1021. The adjusting post 1021 is rotatably connected to the first clamping member 1023 via the flange 211. The first clamping member 1023 is located above the side of the first branch 1011 facing the second branch 1015. The first clamping member 1023 has a first engaging groove 234 on the side facing the vertical portion 1016, which engages with the guide rail 1012. Preferably, the first engaging groove 234 is approximately a dovetail groove.

[0033] The first clamping member 1023 includes a clamping member body 232 connected to the adjusting post 1021, and a cover plate 231 covering the clamping member body 232. A stepped hole 233 is formed at the center of the clamping member body 232. The adjusting post 1021 partially extends into the stepped hole 233, and a flange 211 is received in the stepped hole 233 and is rotatable relative to the clamping member body 232. The cover plate 231 seals the stepped hole 233 to restrict the vertical movement of the adjusting post 1021 relative to the clamping member body 232.

[0034] The support member 103 includes a connecting post 1031 movably passing through the second mounting hole 1014, a mounting seat 1032 mounted on one axial end of the connecting post 1031, and a second clamping member 1033 mounted on the other axial end of the connecting post 1031. An elastic member 104 is sleeved on the outer side of the connecting post 1031. Preferably, the elastic member 104 is a spring. The two ends of the elastic member 104 abut against the second clamping member 1033 and the second branch 1015, respectively. A laser displacement sensor 12, a proximity switch 11 located in front of the laser displacement sensor 12, and a nozzle 41 located on one side of the laser displacement sensor 12 can be mounted on the mounting seat 1032. The second clamping member 1033 is located below the side of the second branch 1015 facing the first branch 1011. The second clamping member 1033 has a recessed second engagement groove 332 on the side facing the vertical portion 1016. The second engagement groove 332 slidably engages with the guide rail 1012. Preferably, the second engagement groove 332 is a dovetail groove. The lower end of the second clamping member 1033, away from the vertical portion 1016, is configured as a slope 331, which slopes upwards. After the support assembly 10 is installed on the frame 100, a heightening shim can be inserted between the frame 100 and the second clamping member 1033 to increase the distance between the mounting base 1032 and the frame 100; or the distance between the mounting base 1032 and the frame 100 can be decreased by rotating the rotating portion 1022 of the adjusting member 102, thereby accommodating different sizes of carbon blocks. The slope 331 facilitates the operator's insertion of the heightening shim between the frame 100 and the second clamping member 1033.

[0035] After the bracket assembly 10 is installed on the frame 100, the distance between the mounting base 1032 and the frame 100 is adjusted by rotating the rotating part 1022 of the adjusting member 102 or by inserting a heightening shim between the frame 100 and the second clamping member 1033. This adjusts the height of the laser displacement sensor 12 and the proximity switch 11. After the heights of the laser displacement sensor 12 and the proximity switch 11 are adjusted, when the slotted carbon block is conveyed to the detection station via the roller conveyor, the proximity switch 11 is triggered, activating the first relay 22 (time relay) to control the laser displacement sensor 12 to perform detection within a set time. The laser displacement sensor 12 is aligned with the slotted gap at a preset minimum sensing distance. If the slotting position is correct, the laser penetrates the gap without returning a signal. If the slotting is offset, the laser irradiates the surface of the carbon block and returns a signal. The laser displacement sensor 12 outputs a signal to trigger the second relay 23, thereby activating the audible and visual alarm light 31 and achieving self-locking.

[0036] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
