[0034] The following will be described in detail in combination with the drawings Figure 1 - the drawings show that: Figure 6 The application will be further described in detail.

[0035] The embodiment of the application discloses a strip thickness detection equipment.

[0036] Reference Figure 1A strip thickness detection device, comprising a rack 1, a mounting base 2 and a thickness detection mechanism 3, wherein the mounting base 2 is arranged at the middle of the width direction of the rack 1, and the mounting base 2 is slidably connected to the rack 1 along the length direction of the rack 1; a driving cylinder 5 is arranged on the rack 1, the cylinder body of the driving cylinder 5 is fixed to the rack 1, and the piston rod of the driving cylinder 5 is connected to the mounting base 2; in use, the mounting base 2 can be driven to slide by the extension and retraction of the piston rod of the driving cylinder 5; and a tank chain 10 is arranged on the rack 1, which is used to guide the related air pipes and wires of the guiding device to move with the mounting base 2.

[0037] Referring to Figure 1 and Figure 2 A positioning structure 6 is arranged on the rack 1, which is used to limit the sliding distance of the mounting base 2; the positioning structure 6 comprises a second lead screw 61, a first abutting block 62, a second abutting block 63 and a guide rod 64, wherein the second lead screw 61 is rotatably arranged on the rack 1, one end of the second lead screw 61 is threadedly connected to the first abutting block 62, the first abutting block 62 slides on the rack 1, one end of the guide rod 64 is fixedly welded to the first abutting block 62, the other end of the guide rod 64 is slidably inserted into the rack 1, and the second abutting block 63 is fixed to the bottom end of the mounting base 2 and abuts against the first abutting block 62.

[0038] Referring to Figure 1 and Figure 2 In use, the worker can drive the first abutting block 62 to slide by rotating the second lead screw 61, and the sliding direction of the first abutting block 62 is guided and limited by the guide rod 64, so that the distance between the first abutting block 62 and the second abutting block 63 can be changed, and the sliding distance of the mounting base 2 can be changed when the mounting base 2 is driven to slide by the driving cylinder 5, that is, the mounting base 2 stops sliding when the second abutting block 63 abuts against the first abutting block 62; by the above-mentioned mode, the strip of different widths can be detected in width, and the strip at different positions can also be detected, so that the applicability is higher.

[0039] Referring to Figure 1 and Figure 3 An avoiding groove 21 is arranged at one end of the length direction of the mounting base 2, the avoiding groove 21 is arranged through in the width direction of the mounting base 2, the transmission direction of the strip is parallel to the width direction of the mounting base 2, and the strip is arranged in the avoiding groove 21; two groups of thickness detection mechanisms 3 are arranged on the upper and lower side walls of the avoiding groove 21 in a symmetrical mode, and a detection area is formed between the two groups of thickness detection mechanisms 3; in use, the strip is continuously transmitted from the avoiding groove 21 to the detection area, then the upper thickness detection mechanism 3 detects the thickness of the strip from above, and the lower thickness detection mechanism 3 detects the thickness of the strip from below, and then the detection results of the two thickness detection mechanisms 3 are averaged to obtain the thickness of the strip.

[0040] With reference to Figure 1 And Figure 3 In the embodiment, the thickness detection mechanism 3 adopts a contact sensor, that is, during the transmission of the strip from the detection area, the probe of the contact sensor is extended, and is retracted when contacting the sidewall of the strip, and then the detection result is transmitted to the external display panel in the form of an electrical signal. In this process, in order to prevent the probe of the contact sensor from causing the strip to shake when it contacts the strip, thereby affecting the accuracy of the thickness detection result of the strip, two sets of limiting assemblies 4 are further arranged on the mounting seat 2. The two sets of limiting assemblies 4 are symmetrically arranged on both sides of the width direction of the mounting seat 2, and are arranged corresponding to the inlet and outlet of the strip in the avoiding groove 21. In use, through the cooperation of the two sets of limiting assemblies 4, the strip is limited on the upper and lower sides without affecting the continuous transmission of the strip, thereby avoiding the problem of shaking of the strip up and down.

[0041] With reference to Figure 3 And Figure 4 The limiting assembly 4 includes a first fixed seat 41, a limiting roller 42, a second fixed seat 43, an abutting roller 44, and a driving structure 45. The first fixed seat 41 is fixed on the upper sidewall of the avoiding groove 21 by bolts. The limiting roller 42 is rotatably connected to the bottom of the first fixed seat 41. The second fixed seat 43 is slidably arranged on the mounting seat 2 along the height direction of the mounting seat 2. The abutting roller 44 is rotatably connected to the top of the mounting seat 2, and the abutting roller 44 and the limiting roller 42 are parallel to each other, and a limiting space is formed between the limiting roller 42 and the abutting roller 44. The strip is transmitted to the detection area after passing through the limiting space. The driving structure 45 is used to drive the second fixed seat 43 to slide. In use, the height of the second fixed seat 43 in the vertical direction is changed by the driving structure 45, so as to change the distance between the abutting roller 44 and the limiting roller 42, so as to ensure that the limiting roller 42 and the abutting roller 44 can abut on the outer wall of the strip, thereby forming a limiting to the strip.

[0042] With reference to Figure 4 And Figure 5The driving structure 45 comprises a driving shaft 451, a worm 452, a worm wheel 453, a screw sleeve 454 and a first lead screw 455. The axis of the first lead screw 455 is parallel to the height direction of the mounting base 2. The top end of the first lead screw 455 is rotationally connected to the bottom of the second fixing base 43. The screw sleeve 454 is coaxially arranged on the first lead screw 455 and is threadedly connected with the first lead screw 455. The worm wheel 453 is coaxially and fixedly connected with the screw sleeve 454. The worm 452 and the worm wheel 453 are rotationally arranged on the mounting base 2. The worm 452 is matched with the worm wheel 453. The driving shaft 451 is coaxially and fixedly connected with the worm 452, and one end of the driving shaft 451 extends to the outside of the mounting base 2. During use, the worm 452 is driven to rotate by rotating the driving shaft 451. The worm 452 is synchronously driven to rotate the worm wheel 453. Under the cooperation of the screw sleeve 454, the worm wheel 453 is driven to slide the first lead screw 455 along the height direction of the mounting base 2, so as to drive the second fixing base 43 to ascend and descend, thereby realizing the adjustment of the position of the abutting roller 44 on the second fixing base 43.

[0043] With reference to Figure 1 and Figure 6 , in order to avoid the strip entering the avoiding groove 21 and the limiting space in an inclined state, two groups of fixing frames 7 are arranged on the rack 1. The two groups of fixing frames 7 are uniformly distributed along the width direction of the rack 1, and the two groups of fixing frames 7 are located on the two sides of the mounting base 2. A supporting roller 8 is rotationally arranged on any one of the two groups of fixing frames 7. During use, the bottom wall of the strip is supported by the cooperation of the two groups of supporting rollers 8, so as to ensure that the strip remains horizontal during transmission in the detection area, thereby ensuring the accuracy of subsequent thickness detection.

[0044] With reference to Figure 1 and Figure 6 , in addition, in order to ensure that the supporting roller 8 can support different passing strips and ensure that strips of different heights can remain in a horizontal state, an adjusting structure 9 is arranged on the fixing frame 7, which can be used to adjust the height of the supporting roller 8. The adjusting structure 9 comprises a sliding frame 91, a third lead screw 92 and a limiting bolt 93. The sliding frame 91 slides on the fixing frame 7 along the height direction of the mounting base 2. The supporting roller 8 is rotationally connected to the top end of the sliding frame 91. A positioning hole 71 is formed in the fixing frame 7. A waist-shaped hole 911 is formed in the sliding frame 91, and the length direction of the waist-shaped hole 911 is parallel to the height direction of the sliding frame 91. One end of the limiting bolt 93 passes through the waist-shaped hole 911 and is threadedly connected in the positioning hole 71.

[0045] With reference to Figure 1 and Figure 6The axis of the third screw rod 92 is parallel to the sliding direction of the sliding frame 91, and the third screw rod 92 is in threaded connection with the fixed frame 7, and the top end of the third screw rod 92 is in abutting connection with the sliding frame 91; when it is needed to adjust the height of the supporting roller 8, the worker first rotates the limiting bolt 93 to loosen the limiting bolt 93, and then rotates the third screw rod 92 to support the sliding frame 91 through the third screw rod 92 and drive the sliding frame 91 to move in the vertical direction, and when the sliding frame 91 is moved to the appropriate position, the limiting bolt 93 is rotated again to abut the sliding frame 91 on the fixed frame 7, so that the height position of the supporting roller 8 is adjusted; in order to ensure the stability of the sliding frame 91 after adjustment, the limiting bolt 93, the positioning hole 71 and the waist-shaped hole 911 are all provided with two groups of corresponding structures in the embodiment.

[0046] The implementation principle of the embodiment of the application is as follows: when used, the device is installed as a whole at the transmission of the strip, then the relative positions of the strip, the rack 1 and the mounting seat 2 are adjusted through the cooperation of the positioning structure 6 and the driving cylinder 5, so that the strip can pass through the avoiding groove 21 and the detection area, then the height of the supporting roller 8 is adjusted through the adjusting structure 9, so that the heights of the two supporting rollers 8 remain consistent, and the two supporting rollers 8 are both abutted on the lower side wall of the strip, so as to ensure that the strip between the two groups of supporting rollers 8 is in a horizontal state, then the height of the abutting roller 44 is adjusted through the driving structure 45, that is, the strip is abutted on the limiting roller 42 through the abutting roller 44, so that the strip is limited up and down through the cooperation of the abutting roller 44 and the limiting roller 42, and the continuous transmission of the strip is not affected, finally the strip in the detection area can be detected through the thickness detection mechanism 3, and the thickness of the strip is the average of the data obtained by the two groups of thickness detection mechanisms 3, the whole use is simple and convenient, and the accuracy of the detection result is ensured.
