Such a structure design, through the cooperation of the rolling wheel and the sliding groove, the sliding connection between the moving plate and the two sliding rods is completed, and the rolling friction between the rolling wheel and the sliding groove is used instead of the sliding friction between the moving plate and the sliding rod, which can effectively reduce the friction and make the movement of the moving plate more smooth.

With such a structure, the front end of the cigarette paper is blocked by the baffle, and the position of the front end of the cigarette paper is limited when the cigarette paper is placed on the moving plate, so as to avoid the problem that the cigarette paper cannot enter between the upper roller and the lower roller due to the too-forward placement position of the cigarette paper. The push plate is used to support the user's hand. When testing, the cigarette paper can be placed on the moving plate, so that the folded part is located outside the moving plate and corresponds to the gap between the upper roller and the lower roller. The front end of the cigarette paper abuts against the baffle. The user's left hand, except the thumb, presses on the cigarette paper to fix the cigarette paper, and the thumb presses on the push plate to push the moving plate, so that the cigarette paper enters between the upper roller and the lower roller to complete the paper test.

[0019] 2. The adjusting shaft, the second ratchet bearing at the end of the adjusting shaft, the driving block matched with the second ratchet bearing, and the driving rod on the driving block and the limiting table on the upper roller are arranged. When the upper roller rotates, the limiting table pushes the driving rod to move, the driving rod drives the driving block to move, the second ratchet rotates in the forward direction, drives the adjusting shaft to rotate, and moves downward, so as to automatically complete the distance adjustment between the upper roller and the lower roller, without manual adjustment, which is simple and convenient.

[0020] 3. The third ratchet bearing at the top end of the adjusting shaft eliminates the influence of the second ratchet bearing rotating in the reverse direction on the adjusting shaft, so as to ensure the adjustment accuracy between the upper roller and the lower roller.

[0021] 4. The driving rod is threadedly connected with the mounting table, the length of the driving rod screwed into the mounting table is adjusted, and the length of the moving distance of the driving block each time is adjusted, so as to change the rotation of the upper roller.

[0022] 5. The fixed frame and the adjusting frame are hinged through the first hinge frame and the second hinge frame, and the third gear, the fourth gear, the fifth gear and the sixth gear are sequentially meshed. When the adjusting frame moves up and down under the action of the adjusting component, the meshing relationship between the third gear, the fourth gear, the fifth gear and the sixth gear does not change, that is, when the distance between the lower roller and the upper roller changes, the lower roller and the upper roller can still keep the same linear speed and opposite rotation direction synchronous motion.

[0023] 6. By moving the movable plate, the upper and lower rollers can be driven to rotate together to complete the extrusion test of cigarette paper. No other power components are needed to drive the upper and lower rollers to rotate, thus reducing manufacturing costs.

[0024] 7. Through the cooperation between the reset spring and the movable plate, after completing a test on the cigarette paper, the cigarette paper is removed and the movable plate is loosened. At this time, the movable plate can automatically reset under the action of the reset spring, which is convenient for the next test. BRIEF DESCRIPTION OF THE DRAWINGS

[0059] The ratio of the number of teeth of the third gear 53 to the number of teeth of the sixth gear 56 is equal to the ratio of the diameter of the lower roller 310 to the diameter of the upper roller 320. The linear velocities of the lower roller 310 and the upper roller 320 during rotation can be ensured to be equal.

[0060] The third gear 53 and the sixth gear 56 have the same number of teeth, and the lower roller 310 and the upper roller 320 have the same diameter size. The third gear 53 and the sixth gear 56 are interchangeable with each other, and the lower roller 310 and the upper roller 320 are interchangeable with each other, so that the practicability is higher.

[0061] The sliding rod 11 is provided with a sliding groove 110, and the two side walls of the moving plate 12 are rotatably provided with rolling wheels 120, and the rolling wheels 120 are located in the sliding groove 110. Through the cooperation of the rolling wheels 120 and the sliding groove 110, the sliding connection between the moving plate 12 and the two sliding rods 11 is completed, and the rolling friction between the rolling wheels 120 and the sliding groove 110 is used to replace the sliding friction between the moving plate 12 and the sliding rod 11, so that the friction can be effectively reduced, and the movement of the moving plate 12 is more smooth.

[0062] The two sliding rods 11 are fixedly provided with a first fixed rod 111 at one end and detachably provided with a second fixed rod 112 at the other end. The maximum sliding position of the moving plate 12 is limited by the first fixed rod 111 and the second fixed rod 112, so as to avoid the problem that the moving plate 12 falls out of the range of the sliding rod 11.

[0063] The lower end surface of the moving plate 12 is further fixedly provided with a fixed seat 2, the fixed seat 2 is fixedly provided with a guide rod 21, the bottom support 10 is further fixedly provided with a blocking seat 22, the blocking seat 22 is provided with a guide hole, the free end of the guide rod 21 is arranged in the guide hole, and the guide rod 21 is sleeved with a reset spring 23 between the fixed seat 2 and the blocking seat 22. Through the cooperation of the reset spring 23 and the moving plate 12, after completing the test on the cigarette paper once, the cigarette paper is taken off, and the moving plate 12 is loosened, at this time, the moving plate 12 can be automatically reset under the action of the reset spring 23, and since the first ratchet bearing 59, the moving plate 12 will not drive the installation shaft to rotate when being reset, so that the next test is facilitated.

[0064] The front end of the moving plate 12 is fixedly provided with a baffle 121, and the rear end is fixedly provided with a push plate 122. The baffle 121 blocks the front end of the cigarette paper, limits the position of the front end of the cigarette paper when the cigarette paper is placed on the moving plate 12, and avoids the problem that the cigarette paper cannot enter between the upper roller 320 and the lower roller 310 due to the too-forward placement position of the cigarette paper; the push plate 122 is used to provide support for the user's hand. When testing, the cigarette paper can be placed on the moving plate 12, so that the folded part is located outside the moving plate 12 and corresponds to the gap between the upper roller 320 and the lower roller 310, the front end of the cigarette paper abuts against the baffle 121, the user's left hand except the thumb presses on the cigarette paper to fix the cigarette paper, and the thumb presses on the push plate 122 to push the moving plate 12, so that the cigarette paper enters between the upper roller 320 and the lower roller 310, and the paper extrusion test is completed.

[0065] In this embodiment, when in use, the cigarette paper is placed on the moving plate 12, so that the folded part of the cigarette paper is located outside the moving plate 12 and corresponds to the gap between the upper roller 320 and the lower roller 310, the front end of the cigarette paper abuts against the baffle 121, the user's left hand except the thumb presses on the cigarette paper to fix the cigarette paper, and the thumb presses on the push plate 122 to push the moving plate 12, so that the cigarette paper enters between the upper roller 320 and the lower roller 310;

[0066] In the process of pushing the moving plate 12, the rack 13 is engaged with the first ratchet bearing 59 to drive the mounting shaft to rotate, the synchronous belt 570 wound between the seventh gear 57 and the eighth gear 58 is driven to rotate the seventh gear 57, the first gear 51 is driven to rotate through the rotating shaft, and the third gear 53 and the sixth gear 56 are driven to rotate, so that the upper roller 320 and the lower roller 310 are driven to rotate;

[0067] That is, when in use, the lower roller 310 and the upper roller 320 rotate simultaneously when the moving plate 12 is pushed, and the cigarette paper preliminarily folded (the preliminary folding refers to folding the cigarette paper along the crease line to make one end of the cigarette paper adhere to the inside of the cigarette paper, without causing excessive extrusion on the crease line) is driven to move forward along with the pushing of the moving plate 12, until the folded part of the cigarette paper enters between the lower roller 310 and the upper roller 320, and the extrusion test on the cigarette paper is completed through the extrusion of the lower roller 310 and the upper roller 320;

[0068] If the extrusion breakage phenomenon does not occur in the first extrusion process, the moving plate 12 is continuously pushed, the upper roller 320 is continuously rotated, the limiting table 321 is in contact with the end of the driving rod 45, the limiting table 321 drives the driving rod 45 to move, the driving rod 45 drives the driving block 42 to further compress the first spring 44, the driving block 42 slides towards the fixed end of the slide rod 43, and the driving teeth 421 on the driving block 42 drive the second ratchet bearing 41 to rotate in the forward direction.

[0069] When the second ratchet bearing 41 rotates in the forward direction, the adjusting shaft 6 threadedly connected with the top end of the support frame 30 is driven to rotate, the adjusting shaft 6 is driven to move downward, the adjusting frame 32 is driven to move downward, and the distance between the upper roller 320 and the lower roller 310 is shortened.

[0070] When the distance between the upper roller 320 and the lower roller 310 is adjusted, the moving plate 12 is loosened, the reset spring 23 automatically resets the moving plate 12, and the moving plate 12 is pushed again for extrusion test.

[0071] The above steps are repeated until the extrusion breakage phenomenon occurs at the crease of the cigarette paper.

[0072] During the adjusting process, the fixed frame 31 and the adjusting frame 32 are hinged through the first hinge frame 530 and the second hinge frame 550, the third gear 53, the fourth gear, the fifth gear 55 and the sixth gear 56 are sequentially meshed, when the adjusting frame 32 moves up and down under the action of the adjusting component 33, the meshing relationship between the third gear 53, the fourth gear, the fifth gear 55 and the sixth gear 56 does not change, that is, when the distance between the lower roller 310 and the upper roller 320 changes, the lower roller 310 and the upper roller 320 can still keep the synchronous movement with the same linear speed and opposite rotating directions.

The description of the specific embodiments is only used to help understand the method of the application and its core idea. It should be pointed out that those skilled in the art can make some improvements and modifications to the application without departing from the principles of the application, and these improvements and modifications also fall within the protection scope of the claims of the application.
