Description

Technical Field

[0001] The present invention belongs to the technical field of detection equipment, and particularly relates to a rangefinder installation device for crease detection. Background Art

[0002] With the development of the economy, the tobacco industry has also flourished. While paying attention to the quality of tobacco shreds, the cigarette cartons are also getting more and more attention.

[0003] The cigarette cartons are divided into hard cartons and soft cartons, and are finally packed in strip cartons. The strip cartons and hard cartons are generally formed by mechanically pressing marks on hard paper, and then folding along the corresponding marks, and finally folding along the creases into corresponding shapes. At present, when the strip cartons and hard cartons enter the factory, their creases will be detected to see if they meet the standards. Due to the large quantity of strip cartons and hard cartons entering the factory, a rangefinding device is generally used to detect their creases to reduce the labor intensity of the inspectors. The continuous and long-term use of the rangefinding device easily causes the rangefinding device to malfunction. In the existing rangefinding device, the installation structure of the rangefinder is complex, so that once a malfunction occurs, it is not easy to disassemble the rangefinder from the rangefinding device, causing additional trouble.

The second horizontal plate 32 is located within the third groove 102, and the second horizontal plate 32 is fixedly installed within the third groove 102 by screws, thereby fixedly installing the second locking post 3 within the second installation groove 101. A first through hole 304 is formed on the second locking post 3, and a first blind hole 303 is formed on the second locking post 3. The first blind hole 303 communicates with the first through hole 304, and the diameter of the first blind hole 303 is larger than that of the first through hole 304. One end of the connecting rod 33 passes through the first through hole 304, and the other end is located within the first blind hole 303. The pressing block 31 is fixedly installed on the connecting rod 33. The second spring 34 is sleeved on the connecting rod 33. One end of the second spring 34 is connected to the bottom of the first blind hole 303, and the other end is connected to the pressing block 31. A second blind hole 104 is formed on the mounting bracket 1, and the second blind hole 104 communicates with the second installation groove 101. The end of the connecting rod 33 passes through the second blind hole 104. By pressing the pressing block 31, under the action of the second spring 34, the connecting rod 33 can move within the first through hole 304 and the second blind hole 104. One end of the connecting rod 33 extending out of the second locking post 3 abuts against one of the second fixing posts 42. As the connecting rod 33 moves, the two second fixing posts 42 approach each other, thereby locking the fuselage of the rangefinder 5 by the fixing bracket 4, so that the rangefinder 5 is fixedly installed within the mounting bracket 1. One side of one of the second fixing posts 42 is beveled, which facilitates the movement of the second fixing post 42 when the connecting rod 33 abuts against the second fixing post 42.

[0037] The mounting frame 1 is provided with a third mounting groove 105, which is connected to the second blind hole 104. A clamping member is installed in the third mounting groove 105, and the clamping member includes a clamping block 35, a connecting plate 36, a ball 353 and a third spring 352. One side of the clamping block 35 is arc-shaped, so that the clamping block 35 will not block the movement of the connecting rod 33. The connecting plate 36 is fixedly installed on the clamping block 35, and a threaded hole 361 is provided on the connecting plate 36. A screw is screwed into the threaded hole 361 to fix the clamping block 35 in the third mounting groove 105. The clamping block 35 is provided with a first clamping groove 351, a third spring 352 is installed in the first clamping groove 351, and a ball 353 is installed in the first clamping groove 351.

The first identification groove 301 and the second identification groove 302 are opposite to each other, so that the second engaging groove 312 is engaged with the ball 353. The cover plate 2 is provided with a second through hole, and the end of the pressing block 31 passes through the cover plate 2 to prevent the second spring 34 from being in a compressed state for a long time and causing deformation.

[0039] In this embodiment, when in use, the cover plate 2 is opened, the transmitting end of the rangefinder 5 is aligned with the first through slot 11, and the transmitting end of the rangefinder 5 is slowly inserted into the first through slot 11. During this process, the body of the rangefinder 5 gradually enters the annular plate 7 and abuts against the spring sheet 71, the rangefinder 5 is initially fixed, and the support plate 75 is moved downward, so that the connecting column 73 gradually moves in the first groove 12, the first spring 74 is compressed, and then the pressing block 31 is pressed downward, so that the connecting rod 33 is aligned with the second fixing column 42 with an inclined surface. As the connecting rod 33 moves downward, the two second fixing posts 42 gradually approach each other and gradually fix the body of the rangefinder 5. When the connecting rod 33 is inserted into the second blind hole 104, the pressing block 31 is rotated to align the first identification groove 301 with the second identification groove 302, so that the ball 353 is clamped into the second clamping groove 312, and then the position of the connecting rod 33 is fixed, so that the fixing frame 4 fixes the rangefinder 5 in the mounting frame 1, so as to avoid slight shaking of the rangefinder 5 during use, which may cause errors in the test results.

[0040] When the rangefinder 5 has been used for a long time and needs to be repaired and maintained, open the cover plate 2, press down the pressing block 31, the connecting rod 33 moves downward, so that the ball 353 disengages from the second clamping groove 312 on the connecting rod 33, rotate the pressing block 31, drive the connecting rod 33 to rotate, under the action of the second spring 34, the connecting rod 33 disengages from the second fixing column 42, so that the two second fixing columns 42 are loosened, thereby enabling the fixing frame 4 to loosen the rangefinder 5. At this time, the first spring 74 resumes deformation, causing the rangefinder 5 to move upward, exposing the fuselage of the rangefinder 5 from the mounting bracket 1. The maintenance personnel can slowly take out the rangefinder 5 directly, which is convenient and fast.

[0041] The above has introduced in detail a rangefinder installation device for crease detection provided by the present invention.
