[0028] A device for detecting the surface flatness of a rubber roller, such as Figure 1 and Figure 2 As shown, including:

[0029] The bracket 10 has a frame structure of a bottom plate and a support plate. The top of the bottom plate is slidably connected to two support plates that can approach each other. The wall surface of the support plate is fixed with a sleeve for limiting the rubber roller. The two ends of the rubber roller are inserted through the sleeve so that the rubber roller can be limited.

[0030] The detection rod 11 is slidably connected to the top of the bottom plate of the bracket 10 and has two rods. A detection module is provided on one side of the two detection rods 11. The detection module includes a displacement sensor and a pressure sensor. A control box should also be installed on the top of the bracket 10. The control box includes a signal receiver and a signal transmitter. The uneven protrusion on the rubber roller applies force to the pressure sensor. The pressure sensor transmits the signal to the signal receiver through the signal transmitter. The signal receiver is connected to the displacement sensor, and the force applied to the detection plate and the displacement of the support plate are displayed on the display. The uneven position on the rubber roller is accurately located to realize the detection of the circumferential surface of the rubber roller. This is an existing well-known technology and will not be described in detail here.

[0031] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the support structure is arranged on the top of the bracket 10 and is used to support the middle section of the rubber roller to suppress the rubber roller from falling. The support structure includes a support block 20 and a support screw 21. The support block 20 is slidably connected to the bracket 10, and the support screw 21 is threadedly connected to the support block 20. The end of the support screw 21 can contact the rubber roller and support the rubber roller. The support block 20 forms a rectangular block structure. The bottom of the support block 20 is provided with an integrally formed protrusion. The top surface of the bottom plate of the bracket 10 is provided with a limiting groove, and the protrusion is slidably connected to the limiting groove. A threaded hole is provided on the top of the support block 20, and the support screw 21 is connected to the threaded hole of the support block 20. The top of the support screw 21 is chamfered to form a spherical surface, and the spherical surface of the support screw 21 can contact the circumferential surface of the rubber roller.

[0032] In the present solution, due to the gravity of the rubber roller itself and the fixed positions at the two ends of the rubber roller, the middle section of the rubber roller is in a suspended state, and the deformation of the middle section is larger than that of the end section, which will affect the detection data of the middle section of the rubber roller. By rotating the support screw 21, the spherical surface of the support screw 21 contacts the middle section of the rubber roller, thereby supporting the middle section of the rubber roller and suppressing the falling deformation of the middle section of the rubber roller. The slidable support block 20 can adjust the support position of the support screw 21, and can be adjusted according to the length of the rubber roller, which helps to improve the detection accuracy, has strong adjustability and high adaptability.

[0033] like Figure 2 and Figure 5As shown, the connection assembly is arranged on the wall of the detection rod 11 and is used to connect the two detection rods 11 to maintain synchronous movement. The connection assembly includes a flip body 30 and a sliding body 31. The flip body 30 is rotatably connected to one of the detection rods 11, and the sliding body 31 is slidably connected to the flip body 30. The sliding body 31 is locked and fixed with the other detection rod 11 through a fastener. The flip body 30 and the sliding body 31 together form a cross arm and tighten the two detection rods 11. The flip body 30 forms a hollow tubular structure. The sliding body 31 and the flip body 30 cooperate with each other. The moving body 31 is slidably connected to the inner wall of the cavity of the flip body 30, and a positioning threaded hole 32 is provided on the wall of the detection rod 11. A fastener can be inserted into the positioning threaded hole 32 to lock the position of the sliding body 31. A positioning threaded hole 32 is provided near the top position of one side of the detection rod 11 connected to the flip body 30, and a positioning threaded hole 32 is provided near the bottom position on the same side of the other detection rod 11. When the flip body 30 is flipped to the horizontal position, the fastener is directly opposite to the positioning threaded hole 32 at the bottom of the detection rod 11. The fastener includes a screw but is not limited to a screw. When the flip body 30 is flipped to the vertical position When the turning body 30 is in the vertical position, the fastener is directly opposite to the positioning threaded hole 32 of the detection rod 11 connected to the turning body 30. As a supplement to the above scheme, by setting the turning body 30 and the sliding body 31, the turning body 30 can be turned to the horizontal position and the sliding body 31 can be pulled to slide, and the screw on the wall of the sliding body 31 is fastened to the positioning threaded hole 32 of the detection rod 11, so that the two detection rods 11 form a whole. By pushing one of the detection rods 11, the other detection rod 11 can be synchronously displaced, so that the two detection rods 11 can detect the same circumferential position of the rubber roller. The two detection rods 11 detect the same circumference of the rubber roller at the same time, which can verify and calibrate the data with each other and reduce the detection error. The sliding body 31 can also be separated from the detection rod 11 to realize the detection of different positions of the rubber roller by the two detection rods 11 to improve the detection efficiency. When the sliding body 31 is separated from the detection rod 11, the sliding body 31 is pushed to slide into the flip body 30, and the flip body 30 is flipped to a vertical displacement. The screw rod is tightened with the positioning threaded hole 32 at the top of the detection rod 11 to realize the storage and fixation of the flip body 30. It is convenient to use and easy to operate.

[0034] The working principle of the utility model is as follows: by rotating the support screw 21, the spherical surface of the support screw 21 contacts the middle section of the rubber roller, thereby supporting the middle section of the rubber roller and suppressing the falling deformation of the middle section of the rubber roller. The slidable support block 20 can adjust the support position of the support screw 21, flip the flip body 30 to a horizontal position and pull the sliding body 31 to slide, and tighten the screw on the wall of the sliding body 31 to the positioning threaded hole 32 of the detection rod 11, so that the two detection rods 11 form a whole, and one of the detection rods 11 can be pushed to drive the other detection rod 11 to move synchronously. Furthermore, the two detection rods 11 can detect the same circumferential position of the rubber roller, and the two detection rods 11 detect the same circumference of the rubber roller at the same time, so that the data can be verified and calibrated with each other. The sliding body 31 can also be separated from the detection rod 11 to realize the detection of different positions of the rubber roller by the two detection rods 11, so as to improve the detection efficiency. When the sliding body 31 is separated from the detection rod 11, the sliding body 31 is pushed to slide into the flip body 30, and the flip body 30 is flipped to a vertical displacement, and the screw rod is fastened to the positioning threaded hole 32 at the top of the detection rod 11 to realize the storage and fixation of the flip body 30.

[0035] The detection module includes a displacement sensor and a pressure sensor. A control box should also be installed on the top of the bracket 10. The control box includes a signal receiver and a signal transmitter. The uneven protrusions on the rubber roller apply force to the pressure sensor. The pressure sensor will transmit the signal to the signal receiver through the signal transmitter. The signal receiver is connected to the displacement sensor, and the force applied to the detection plate and the displacement of the support plate are displayed on the display. The uneven position on the rubber roller is accurately located to realize the detection of the circular surface of the rubber roller. This is an existing well-known technology and will not be elaborated here.
