[0096] When the motor 130 works, it drives the rotating plate 140 to rotate as a whole, so as to adjust the irradiation position of the vertical laser profiler 150;

[0097] The vertical laser profiler 150 is used for detecting the vertical profile of the product;

[0098] The rotating axis of the output end of the motor 130 is perpendicular to the ground, and the output end of the vertical laser profiler 150 faces the bottom plate 110;

[0101] The output ends of the two outer diameter measuring instruments 190 are oppositely arranged, and the fixed cylinder 210 is located between the two outer diameter measuring instruments 190;

[0102] The length direction of the motorized sliding table 160 is perpendicular to the ground, and the length direction of the motorized sliding table 160 is the sliding direction of the sliding block 170;

[0103] The fixing assembly 200 further comprises a telescopic rod 240;

[0104] The telescopic rod 240 is located in the fixed cylinder 210, the lower end of the telescopic rod 240 is fixed on the bottom plate 110, and the upper end of the telescopic rod 240 is fixed on the lower side of the abutting block 230;

[0105] The telescopic rod 240 is an electric telescopic rod;

[0106] When the telescopic rod 240 is retracted to drive the abutting block 230 to descend, the abutting block 230 presses the spring sheet 220, so that the spring sheet 220 expands outward to abut against the inner wall of the cylindrical product to be detected;

[0107] The vertical laser profilometer 150, the electric sliding table 160, the outer diameter measuring instrument 190 and the telescopic rod 240 are all prior art and will not be described here.

[0108] A detection method of a size laser detection device of an alcohol recovery device, using the device, comprising the following steps:

[0109] S1: The cylindrical product to be detected is sleeved on the fixed cylinder 210 and the abutting block 230;

[0110] S2: The telescopic rod 240 is retracted to drive the abutting block 230 to descend, so that the spring sheet 220 expands outward to abut against the inner wall of the cylindrical product, and the position of the cylindrical product is fixed;

[0111] S3: In the process of abutting against the cylindrical product by the outward expansion of the spring sheet 220, the cylindrical product not located at the detection center can be moved to the center position;

[0112] S4: The motor 130 drives the rotating plate 140 to rotate, moves the vertical laser profilometer 150 to the upper end of the cylindrical product, detects the cylindrical product by the vertical laser profilometer 150, and detects whether the outer diameter of the cylindrical product is qualified by the two outer diameter measuring instruments 190;

[0113] S5: The outer diameter measuring instrument 190 can be driven to rise or descend by the electric sliding table 160 to completely detect the surface of the cylindrical product;

[0114] S6: After the detection is completed, the rotating plate 140 is reset, the abutting block 230 is reset to cancel the limiting of the cylindrical product, and then the cylindrical product can be taken off.

[0115] Compared with the prior art, by changing the abutting block 230 into a whole conical shape, the contact area between the cylindrical product and the upper end of the abutting block 230 is reduced, the efficiency of putting the cylindrical product is improved, the conical shape can guide the cylindrical product, the efficiency of putting the product is further improved, the detection efficiency is improved, the product damage is reduced, the conical abutting block 230 can more smoothly guide the product to enter the fixed position, the collision and friction are reduced, and the risk of product damage is reduced.

[0116] Example 2: In Example 1, by transforming the entire contact block 230 into a cone shape, insertion efficiency is improved. However, during use, the fixing effect of the spring sheet 220 against the inner wall of the cylindrical product after deformation is poor, resulting in poor stability and low detection accuracy. Furthermore, when moving the cylindrical product by contacting it with the spring sheet 220, efficiency is poor when the offset position is far, and the cylindrical product may tilt. Therefore, the solution in Example 1 is improved, such as... Figures 7-11 As shown:

[0117] The fixing component 200 also includes an abutment ring 250;

[0118] The contact ring 250 is annular and made of rubber.

[0119] The abutment ring 250 is fixed to the outer ring of the spring sheet 220;

[0120] When the telescopic rod 240 retracts and causes the abutment block 230 to descend, the abutment block 230 presses the spring sheet 220, causing the spring sheet 220 to expand outward, and causing the abutment ring 250 to abut against the inner wall of the cylindrical product to be tested.

[0121] It also includes an auxiliary component 300, which includes a movable plate 310, a roller 320, a reset rope 330, and a winder 370;

[0122] The movable plate 310 is a cylindrical shape that runs vertically through the cylinder, and the movable plate 310 is sleeved on the outer ring of the fixed cylinder 210.

[0123] In the initial state, the axis of the moving plate 310 and the axis of the fixed cylinder 210 are on the same straight line;

[0124] A gap is left between the inner ring of the movable plate 310 and the outer ring of the fixed cylinder 210;

[0125] There are multiple winders 370 and reset ropes 330, and the number of winders 370 is the same as the number of reset ropes 330, and they correspond one-to-one.

[0126] The winding device 370 is fixed to the inner ring of the moving plate 310, the reset rope 330 is wound inside the winding device 370, and the end of the reset rope 330 away from the winding device 370 is fixed to the outer ring of the fixed cylinder 210.

[0127] The winder 370 is used to automatically wind up and reset the rope 330;

[0128] Multiple winders 370 are evenly spaced in a ring;

[0129] The roller 320 is fixed on the lower side of the moving plate 310, is placed on the upper side of the bottom plate 110, and is a universal wheel;

[0130] The winder 370 is an automatic winder, which is a prior art and will not be described here.

[0131] In use, when the spring sheet 220 is deformed by being retracted through the telescopic rod 240 and abuts against the inner wall of the cylindrical product, the spring sheet 220 is deformed together with the abutting ring 250 outside, so that the abutting ring 250 made of rubber abuts against the inner wall of the cylindrical product to fix the inner wall of the cylindrical product; when the cylindrical product that does not locate at the detection center is abutted, the cylindrical product will move together with the moving plate 310 on the bottom side to pull the reset rope 330; after the detection is completed, and in the resetting process of the spring sheet 220, the deformed abutting ring 250 has a certain elastic force, which will assist the resetting of the spring sheet 220, and when the cylindrical product is removed from the moving plate 310, the moving plate 310 will be reset by the winding tension of the winder 370.

[0132] The deformed abutting ring 250 can be attached to the inner wall of the cylindrical product, the friction force is increased to improve the fixing effect on the cylindrical product, so as to improve the detection efficiency and avoid low stability in the detection process, which leads to multiple detections and reduces the accuracy; and the rubber material is used to contact the inner wall of the cylindrical product, which will not damage the inner wall of the product during contact, so as to affect the quality of the product; and in the resetting process of the deformed abutting ring 250, the elastic force will assist the resetting of the spring sheet 220 to improve the disassembly efficiency; and in the process of abutting the cylindrical product by the abutting ring 250, the cylindrical product that does not locate at the detection center can be quickly moved by cooperation between the abutting ring 250 and the moving plate 310, so as to improve the fixing efficiency of the cylindrical product and thus improve the detection efficiency of the product.

[0133] In the above embodiment, the rubber abutting ring 250 is attached to the inner wall of the cylindrical product to improve the fixing effect, but in use, the attachment effect of the deformed abutting ring 250 to the inner wall of the cylindrical product is poor, so that the fixing effect of the device on the cylindrical product is poor; at the same time, the moving effect of the deformed abutting ring 250 on the inner wall of the cylindrical product that is deformed by the spring sheet 220 is poor, and accordingly, the scheme of embodiment two is improved, as shown in Figures 12-14

[0134] The abutting ring 250 is hollow and has a gas bag structure;

[0135] The fixing assembly 200 further comprises a gas pump 260 and a gas conveying pipe 270.​

[0136] The air pump one 260 is fixed on the upper side of the bottom plate 110, and the air pump one 260 is located in the fixed cylinder 210;

[0137] One end of the air pipe 270 is in communication with the output end of the air pump one 260, and the end of the air pipe 270 away from the air pump one 260 is in communication with the internal cavity of the abutting ring 250;

[0138] When the air pump one 260 works, it can inflate or deflate to make the abutting ring 250 expand or retract.

[0139] Place the cylindrical product on the moving plate 310. During the deformation of the spring sheet 220, inflate the internal cavity of the abutting ring 250 through the air pump one 260 to make the abutting ring 250 expand. The expanded abutting ring 250 is in close contact with the cylindrical product, and during the expansion of the abutting ring 250, the cylindrical product that is not located at the center of the detection device can be quickly moved to the center of the detection position. The cylindrical product moves on the moving plate 310, and after the detection of the cylindrical product is completed, the moving plate 310 is reset by winding the reset rope 330 through the winder 370.

[0140] Through the expansion of the abutting ring 250, the contact area between the abutting ring 250 and the inner wall of the cylindrical product is increased, thereby improving the fixing effect on the product position. During the expansion of the abutting ring 250, the cylindrical product that is not located at the center of the detection can be quickly moved through cooperation with the moving plate 310, thereby further improving the fixing efficiency of the cylindrical product and improving the detection efficiency of the product. Further, the expansion of the abutting ring 250 can better protect the surface of the product and reduce damage caused by pressure and friction during the fixing process.

[0141] In use, the expanded abutting ring 250 abuts against the cylindrical product to improve the fixing effect, but the device can also be improved to improve the fixing effect and efficiency of the cylindrical product. When the cylindrical product is abutted by the expanded abutting ring 250 and the deformation of the spring sheet 220 alone, the stability of the cylindrical product is poor, and the abutted cylindrical product may be tilted. Therefore, the scheme of example three is improved as shown in Figures 15-18

[0142] The auxiliary assembly 300 further comprises a fixing ring 340, an abutting air bag 350, and an air pump two 360;

[0143] The fixing ring 340 is a cylindrical body penetrating from top to bottom, the fixing ring 340 is sleeved on the outer circle of the moving plate 310, and the fixing ring 340 is fixed on the upper side of the bottom plate 110.​

[0145] A gap is left between the inner ring of the fixed ring 340 and the moving plate 310;

[0146] The abutting air bag 350 is annular, and its axis is in line with the axis of the fixed ring 340, and it is fixed to the inner ring of the fixed ring 340;

[0147] The air pump two 360 is fixed to the outer ring of the fixed ring 340, and its output end is in communication with the inside of the abutting air bag 350;

[0148] When the air pump two 360 works, the abutting air bag 350 expands or shrinks, and the expanded abutting air bag 350 can abut against the outer wall of the product to fix the position of the product;

[0149] The abutting air bag 350 is located below the abutting ring 250, and the expanded abutting air bag 350 is close to the lower end of the product to be detected.

[0150] In use, the cylindrical product is placed between the fixed cylinder 210 and the fixed ring 340, and on the moving plate 310, and is fixed by the deformation of the spring sheet 220 and the expansion of the abutting ring 250 against the inner wall of the cylindrical product, and the center position is moved while the air pump two 360 works to deform the abutting air bag 350, and the deformed abutting air bag 350 abuts against the cylindrical product together with the abutting ring 250 to quickly locate the center position of the detection, and the inner and outer double layers fix the position of the cylindrical product; when the cylindrical product is removed, the spring sheet 220 resets, the abutting ring 250 shrinks, the abutting air bag 350 does not shrink, and after the cylindrical product is pulled out from the abutting air bag 350, the abutting air bag 350 continues to expand, and the expanded abutting air bag 350 is located below the cylindrical product, and after the cylindrical product slides and falls, it falls on the abutting air bag 350.

[0151] Through the inflation of the abutting air bag 350 and the abutting ring 250 together, the efficiency of moving the cylindrical product to the detection center can be improved; and the abutting air bag 350 is located at the lower end of the abutting ring 250, effectively avoiding the instability of the moving cylindrical product due to the high center of gravity during the abutting movement, and the inclination; improving the fixing effect, the clamping mode of the double air bag makes the product more stable, reduces the measurement error caused by the shaking or movement of the product during the measurement, and further improves the detection efficiency; when the cylindrical product is taken off, the abutting air bag 350 does not retract, and the abutting air bag 350 continues to inflate, after the cylindrical product slides and falls off, the cylindrical product can fall on the abutting air bag 350, and the abutting air bag 350 can play a buffering protection effect.

[0152] The above only describes the preferred embodiments of the present application and is not intended to limit the present application. For those skilled in the art, the present application can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
