Description

Technical Field

[0001] The invention belongs to the technical field of cigarette production detection, and in particular relates to a cigarette paper cutter. Background Art

[0002] As the content of cigarette rods and box wrapping paper becomes richer, the substrates, printing processes, and inks used are becoming more diverse and complex, so their physical and chemical properties need to be tested before use. The physical property test of wrapping paper includes testing its bending resistance. First, the crease-free area of ​​the wrapping paper is cut to obtain a sample, and then the corresponding sample is subjected to a pressure test. However, when the wrapping paper is cut, the pressure of the knife leaves an upturned burr on the edge of the wrapping paper sample, that is, the cross-section of the sample is U-shaped, which increases the bending resistance of the sample cigarette paper and affects the test results. At the same time, when the staff is placing or taking the cigarette paper, it is easy to come into contact with the knife, which poses a great safety hazard. Summary of the invention

[0003] Based on the problems mentioned in the above background technology, the present invention provides a cigarette paper cutter for solving the problem that when the packaging paper is cut, the pressure of the tool leaves upturned burrs on the edges of the packaging paper sample, which increases the bending resistance of the sample cigarette paper and affects the test results. At the same time, the existing device has great safety hazards.

[0004] The technical solution adopted by the present invention is as follows:

[0005] The cam is provided with a plurality of camshafts, each of which is provided with a plurality of camshafts, each of which is provided with a plurality of camshafts, each of which is provided with a plurality of camshafts, each of which is provided with a plurality of camshafts. The cam is provided with a first end fixedly mounted on the support frame, and the second end fixedly mounted on the support frame is provided with a second end fixedly mounted on the support frame.

[0006] Furthermore, a first hinge groove is vertically downwardly formed at the top of the mold platform, and a second hinge groove is vertically upwardly formed at the bottom of the mold platform. The depths of the first hinge groove and the second hinge groove are both smaller than the thickness of the mold platform. The first hinge frame is hinged in the first hinge groove, and the second hinge frame is hinged in the second hinge groove. The first hinge groove can limit the transitional rotation of the first hinge frame, so that the pressure plate can be kept in an inclined state under the limiting effect of the first hinge groove after being lifted, which is convenient for use; the second hinge frame is limited by the second hinge groove to prevent the lower part of the second hinge frame from excessively rotating downward under the pressure of the falling platform, causing the annular cutter to disengage from the first knife groove.

[0007] Furthermore, the inner wall of the annular cutter fits the outer wall of the die table, which reduces the gap between the blade area of ​​the annular cutter and the outer wall of the die table during cutting, making the cut of the cigarette paper more neat and avoiding the edge of the cigarette paper from being greatly warped after cutting.

[0008] Specifically, the bottom end of the die table is provided with a rounded corner, which can make it easier for the annular cutter to fit into the first cutter groove when the cutter table is installed.

[0009] Furthermore, a second limiting column is installed at the top of the knife seat, a blind hole corresponding to the second limiting column is opened at the bottom of the placement table, and the second limiting column is inserted into the blind hole. The movement of the knife seat is guided by the second limiting column to prevent the knife seat from tilting during movement and causing damage to the annular cutter.

[0010] Furthermore, two slides are installed on the pressure plate, and the two slides are respectively located on both sides of the second slide groove. The slide is provided with a slide rail, and both sides of the second wedge block are provided with a third slide groove matching the slide rail. Under the action of the slide, the sliding of the second wedge block can be guided and limited to avoid the second wedge block from deviating, causing the smoothing block to deviate and block the first knife groove and the second knife groove, causing interference with the movement of the annular cutter and affecting the cutting.

[0011] Furthermore, a handle is provided at the bottom end of the pressure rod, a fourth slide groove is provided in the handle, a pull rod is slidably installed in the fourth slide groove, the pull rod is fixedly connected to the traction rod, the pressure rod can be conveniently rotated by the handle, and the setting of the pull rod facilitates pulling the traction rod, which is easy to use.

[0012] Furthermore, a third spring is sleeved on one end of the traction rod, and a limiting ring is fixedly installed on one end of the third spring. The third spring is located in the second mounting groove and can return to its original position by itself after the traction rod moves through the third spring, thereby avoiding the second wedge block being unable to force the first wedge block to return to its original position due to the squeezing of the second spring, resulting in the second wedge block being unable to return to its original position normally and causing the smoothing block to block the first knife groove.

[0013] Beneficial effects of the present invention:

[0014] 1. After the pressing plate of the present invention is covered, the pressing rod can continue to rotate downward under the action of the first spring to squeeze the force-bearing rod to lift the push rod. The lifting of the push rod causes the knife seat to rise and drives the annular cutter to rise to cut the cigarette paper. Since the inner wall of the annular cutter fits the outer wall of the die table, the gap between the blade area of ​​the annular cutter and the outer wall of the die table can be reduced during cutting, making the cut of the cigarette paper more neat, avoiding the edge of the cigarette paper from being greatly warped after cutting, resulting in an enhanced anti-bending ability of the cigarette paper, and reducing the impact on the test results;

[0015] 2. The first wedge is driven to move by the traction rod, and the first wedge forces the second wedge to drive the smoothing block to move to both sides. After cutting, the smoothing block can be used to smooth the edges of the cigarette paper on both sides, so as to avoid the problem that the edges of the cigarette paper are greatly warped after cutting, which leads to the increase of the anti-bending ability of the cigarette paper and affects the test results;

[0016] 3. After the pressure plate is lifted, the circular cutter will automatically enter the first knife groove under the action of the gravity of the knife table. The staff will not come into contact with the circular cutter when placing or taking cigarette paper, which is very safe. BRIEF DESCRIPTION OF THE DRAWINGS

The annular cutter 33 is installed on the top of the knife seat 31, and the annular cutter 33 is located in the first knife groove 121. A reserved groove 32 is provided on the knife seat 31, and the fixing column 141 is located in the reserved groove 32. A second knife groove 21 corresponding to the first knife groove 121 is provided on the pressing plate 2, and a hinge seat 23 is provided on the pressing plate 2. A smoothing mechanism 5 is hinged on the hinge seat 23, and the smoothing mechanism 5 includes a pressing rod 51, and a first spring 53 is installed between the pressing rod 51 and the pressing plate 2. The pressing rod 51 is provided with a second spring 53. A mounting groove 511 and a second mounting groove 512, a traction rod 55 is passed through the pressure rod 51, a first wedge block 552 is installed on the traction rod 55, a first slide groove 211 is opened at the bottom end of the pressure plate 2, and a second slide groove 212 is opened at the top end, a smoothing block 58 is arranged in the first slide groove 211, and two second wedge blocks 57 are arranged in the second slide groove 212, the second wedge block 57 is fixedly connected to the first wedge block 552, and the second wedge block 57 is slidably installed on the pressure plate 2, the second wedge block 57 corresponds to the first wedge block 552, and two limit seats 24 are arranged on the pressure plate 2. The second wedge blocks 57 are each provided with a first limiting column 572, and the two first limiting columns 572 are respectively slidably inserted into the limiting seat 24, and the first limiting columns 572 are each sleeved with a second spring 573, and the second spring 573 is located between the limiting seat 24 and the second wedge block 57. When the second spring 573 is in a free state, the outer wall of the smoothing block 58 is flush with the outer wall corresponding to the mold table 12, and the lifting frame 4 includes a fixedly connected force rod 42, a second articulated frame 41 and a push rod 43, the second articulated frame 41 is hinged on the mold table 12, and the push rod 43 is in sliding contact with the bottom end of the tool holder 31.

[0034] Specifically, the top of the mold platform 12 is provided with a first hinge groove 111 vertically downward, and the bottom of the mold platform 12 is provided with a second hinge groove 112 vertically upward. The depth dimensions of the first hinge groove 111 and the second hinge groove 112 are both smaller than the thickness dimension of the mold platform 12. The first hinge frame 22 is hinged in the first hinge groove 111, and the second hinge frame 41 is hinged in the second hinge groove 112. The first hinge groove 111 can limit the transitional rotation of the first hinge frame 22, so that the pressing plate 2 can be kept in an inclined state under the limiting effect of the first hinge groove 111 after being lifted, which is convenient for use; the second hinge groove 112 is used to limit the second hinge frame 41, so as to prevent the lower part of the second hinge frame 41 from excessively rotating downward under the pressure of the falling platform 3, causing the annular cutter 33 to be separated from the first knife groove 121.

[0035] Specifically, the inner wall of the annular cutter 33 fits against the outer wall of the die table 12. When cutting, the annular cutter 33 moves upward close to the die table 12, reducing the gap between the blade area of ​​the annular cutter 33 and the outer wall of the die table 12 during cutting, making the cut of the cigarette paper more neat.

[0036] Specifically, a rounded corner 122 is provided at the bottom end of the mold stage 12 . When the tool stage 3 is installed, the rounded corner 122 is used to guide the annular cutter 3 , and the annular cutter 3 can be better inserted into the first tool groove 121 along the rounded corner 122 .

[0037] Specifically, a second limiting column 35 is installed at the top of the knife seat 31, and a blind hole corresponding to the second limiting column 35 is opened at the bottom of the placement table 11, and the second limiting column 35 is inserted into the blind hole. The movement of the knife seat 31 is guided by the second limiting column 35 to prevent the knife seat 31 from tilting during movement and causing damage to the annular cutter 33.

[0038] Specifically, two relatively arranged slides 56 are installed on the pressure plate 2, and the two slides 56 are respectively located on both sides of the second slide groove 212. A slide rail 561 is provided on the slide 56, and a third slide groove 571 matching the slide rail 561 is opened on both sides of the second wedge block 57. Under the action of the slide 56, the sliding of the second wedge block 57 can be guided and limited to avoid the deflection of the second wedge block 57, which causes the smoothing block 57 to deflect and block the first knife groove 121 and the second knife groove 21, causing interference with the movement of the annular cutter 33 and affecting the cutting.

[0039] Specifically, a handle 54 is provided at the bottom end of the pressure rod 51, and a fourth slide groove 541 is opened in the handle 54. A pull rod 551 is slidably installed in the fourth slide groove 541. The pull rod 551 is fixedly connected to the traction rod 55. The pressure rod 51 can be rotated by pulling the handle 54. When the traction rod 55 needs to be pulled, the handle 551 can be directly pulled by fingers. It is more convenient to use.

[0040] Specifically, one end of the traction rod 55 is sleeved with a third spring 553, and the traction rod 55 is fixedly installed with a limiting ring 554 on one end of the third spring 553. The third spring 553 is located in the second mounting groove 512. When the first wedge block 552 returns, the second wedge block 57 returns under the pressure of the second spring 573, forcing the first wedge block 552 to return. At the same time, the third spring 553 drives the first wedge block 552 to return by driving the traction rod 55 to return, so as to better prevent the first wedge block 552 from getting stuck in the second wedge block 57 and causing the smoothing block to be unable to return.

[0041] When using the cutting cigarette paper, the packaging paper is placed flat on the placement table 11, and the mold table 12 is located in the non-folding area of ​​the packaging paper. Then, the pressure rod 51 is pulled by the handle 54 to drive the pressing plate 2 to rotate. After the pressing plate 2 and the placement table 11 clamp the cigarette paper to be cut, the pressing plate 22 cannot continue to rotate. The pressure rod 51 continues to rotate. The first spring 53 compresses the pressure rod 51 and squeezes the force-bearing rod 42. The second hinge frame 41 rotates to drive the push rod 43 to rise and lift the knife seat 31 to drive the annular cutter 33 to rise and cut the cigarette paper. After cutting, release the handle 54, and the pressure rod 51 returns to its original position under the action of the first spring 53. After the force-bearing rod 42 loses pressure, the push rod 43 descends under the action of gravity of the knife platform 3, and the annular cutter 33 returns to its position and enters the first knife groove 121. At this time, the pressing plate 2 is still pressed on the cigarette paper; then the handle 54 is held again and the pull rod 551 is pulled by the fingers to drive the traction rod 55 to move. When the traction rod 55 moves, it drives the first wedge block 552 to move. When the first wedge block 552 moves, it forces the second wedge block 57 to move to both sides. The second wedge block 57 drives the smoothing block 58 to move to both sides to smooth the edge of the cigarette paper to prevent the edge of the cigarette paper from curling up and affecting the detection of the bending resistance of the cigarette paper. Then, the pressing rod 55 is pulled to lift the pressing plate 2, so that the pressing plate 2 returns to its position and the cigarette paper can be taken out.
