Description

Technical Field

[0001] The present invention belongs to the technical field of cigarette production detection, and particularly relates to a roller-type flattening and cutting device. Background Art

[0002] To avoid the cigarette box being too soft and affecting the user experience, in the cigarette box wrapping paper preparation process, it is necessary to test the softness of the cigarette paper. During the test, first, the non-creased area of the wrapping paper is cut to obtain a sample, and then a pressure test is carried out corresponding to the sample. However, when the wrapping paper is cut, due to the pressure of the cutting tool, the edges of the wrapping paper sample leave upwardly warped indentations, that is, the cross-section of the sample is U-shaped, resulting in an increase in the bending resistance of the sample cigarette paper and affecting the test results. At the same time, currently, the cutting tool of the cutting device is external, and it is easy for the staff to contact the cutting tool when placing or taking the cigarette paper, and there are relatively large safety hazards. Summary of the Invention

[0003] Based on the problems mentioned in the above background art, the present invention provides a roller-type flattening and cutting device, which is used to solve the problems that when the wrapping paper is cut currently, due to the pressure of the cutting tool, the edges of the wrapping paper sample leave upwardly warped indentations, resulting in an increase in the bending resistance of the sample cigarette paper and affecting the test results, and at the same time, there are relatively large safety hazards in the existing device.

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

[0005] A roller-type flattening and cutting device includes a placement table. A base is integrally formed at the bottom of the placement table. A first knife groove is provided between the placement table and the die table. A cross plate is installed on the base. A fixed column is installed on the cross plate. A pressing plate and a jacking frame are hingedly installed on the placement table. A knife table is provided above one end of the lower part of the die table of the jacking frame. The knife table includes a knife seat and an annular cutting knife. The annular cutting knife is installed at the top end of the knife seat. The annular cutting knife is located in the first knife groove. The cutting edge of the annular cutting knife is coplanar with the inner wall of the annular cutting knife, and the inner wall of the annular cutting knife is attached to the groove wall of the second knife groove. A reserved groove is formed on the knife seat. The fixed column is located in the reserved groove. Two installation grooves are formed on the placement table. A sliding rolling mechanism is installed in the installation groove. A guide rod is installed in the installation groove. The sliding rolling mechanism is slidably sleeved on the guide rod. A return spring is sleeved on the guide rod. A first pulley and a second pulley are installed at the bottom end of the placement table. An elastic traction rope is fixedly installed on the sliding rolling mechanism. The free end of the elastic traction rope passes through the first chute and the second pulley and is fixedly installed on the pressing plate. A second knife groove corresponding to the first knife groove is formed on the pressing plate. A hinge seat is provided on the pressing plate. A pressing rod is hinged on the hinge seat. A connecting spring is installed between the pressing rod and the pressing plate. The jacking frame includes a force-bearing rod, a second hinge frame and a jacking rod which are fixedly connected. The second hinge frame is hinged on the die table. The jacking rod is in sliding contact with the bottom end of the knife seat.

[0006] On the basis of the above solution, the present invention has also made the following improvements:

[0007] Furthermore, a first hinge frame is integrally formed on the pressing plate. The pressing plate is hinged to the die table through the first hinge frame, and a limiting frame corresponding to the first hinge frame is installed on the placing table. The limiting frame can limit the excessive rotation of the first hinge frame, so that after the pressing plate is lifted, it remains in an inclined state under the limiting action of the limiting frame, avoiding the backward fall of the pressing plate and facilitating use.

[0008] Furthermore, the bottom end of the die table is provided with a rounded corner. The setting of the rounded corner can make it easier for the annular cutter to be stuck into the first cutter groove when the cutter table is installed.

[0009] Furthermore, a first limiting column is installed at the top end of the tool holder, a blind hole corresponding to the first limiting column is opened at the bottom end of the placing table, and the first limiting column is inserted into the blind hole. The movement of the tool holder is guided by the first limiting column, avoiding damage to the annular cutter caused by the inclination of the tool holder during movement.

[0010] Furthermore, the installation grooves are located on both sides of the first cutter groove. The installation grooves include a first sliding groove, a second sliding groove and a third sliding groove. The first sliding groove is communicated with the first cutter groove, the second sliding groove communicates the first sliding groove and the third sliding groove. The sliding rolling mechanism includes two sliding seats and pressing rollers installed on the sliding seats. The sliding seat includes a roller sliding table, a connecting frame, an upper sliding table and an installation frame. The roller sliding table and the upper sliding table are respectively installed at both ends of the connecting frame. The roller sliding table is slidably sleeved on the guiding rod. The connecting frame is located in the third sliding groove, the upper sliding table is located in the first sliding groove, the installation frame is installed on the upper sliding table, the top end of the upper sliding table is flush with the top end of the die table, and the distance from the side wall of the die table to the side wall of the first sliding groove is equal to the width dimension of the upper sliding table. The pressing rollers are installed on the installation frame. The upper sliding table can make up for the gap on both sides of the die table due to the first sliding groove, avoiding the situation that both sides of the cigarette paper are suspended and not convenient for rolling and smoothing during the rolling of the cigarette paper after cutting due to the first sliding groove.

[0011] Furthermore, adjustment grooves are respectively formed on the installation frames, adjustment blocks are slidably installed in the adjustment grooves, adjustment springs are fixedly installed at the top ends of the adjustment blocks, and both ends of the pressing rollers are respectively installed on the two adjustment blocks. The pressing rollers are in flexible contact with the die table through the adjustment springs, so as to facilitate the pressing rollers to better roll the cigarette paper.

[0012] Furthermore, a handle is provided at the bottom end of the pressing rod, which is convenient for rotating the pressing rod and convenient for use.

[0013] The beneficial effects of the present invention:

[0014] 1. After the pressing plate covers down, under the action of the connecting spring, the pressing rod can continue to rotate downward to squeeze the stress rod, causing the ejector rod to lift. The lifting of the ejector rod makes the tool holder rise, driving the annular cutter to rise to cut the cigarette paper. Since the inner wall of the annular cutter fits with the outer wall of the mold table, the gap between the cutting edge area of the annular cutter and the outer wall of the mold table during cutting can be reduced, making the cut of the paper piece more neat, avoiding the problem that the edge of the paper piece warps significantly after cutting, resulting in an increase in the bending resistance of the paper piece, and reducing the impact on the test results;

[0015] 2. When the pressing plate rotates and covers down, the elastic traction rope can be used to pull the sliding rolling mechanism to move, avoiding the interference of the sliding rolling mechanism with the pressing plate and preventing the pressing plate from covering down; when the pressing plate returns after cutting, the sliding rolling mechanism can be driven by the return spring to roll the cut cigarette paper by itself to smooth the edge of the sample paper piece, avoiding the warping of the edge of the sample paper piece caused by cutting extrusion, which affects the test result; the pressing plate can complete the cutting and rolling smoothing of the cigarette paper by covering down and then lifting and returning, and the operation is very convenient;

[0016] 3. After the pressing plate is lifted, the annular cutter will automatically enter the first cutter groove under the action of the gravity of the tool holder. Workers will not come into contact with the annular cutter when placing and taking the paper piece, and the safety is relatively high. BRIEF DESCRIPTION OF THE DRAWINGS

The pressing roller 57 is installed on the mounting frame 52. A second connecting seat 542 is installed on the roller sliding table 54. One end of the elastic traction rope 6 is fixed to the second connecting seat 542. The upper sliding table 51 can fill the gap on both sides of the die table 12 due to the first sliding groove 111, avoiding the situation that when the cigarette paper is rolled after cutting, the two sides of the cigarette paper are suspended due to the first sliding groove 111, which is not convenient for rolling and smoothing.

[0036] Specifically, adjusting grooves 521 are formed in the mounting frames 52. Adjusting blocks 55 are slidably installed in the adjusting grooves 521. Adjusting springs 56 are fixedly installed at the top ends of the adjusting blocks 55. Both ends of the pressing roller 57 are respectively installed on the two adjusting blocks 55. The pressing roller 57 is in flexible contact with the die table 12 through the adjusting springs 56, so as to facilitate the pressing roller 57 to better roll the cigarette paper.

[0037] Specifically, a handle 26 is provided at the bottom end of the pressing rod 24, which facilitates the rotation of the pressing rod 24 through the handle 26 and is convenient for use.

[0038] When using the cutting paper sheet, place the wrapping paper flat on the placing table 11 and make the die table 12 located in the non-crease area of the wrapping paper. Then, pull the pressing rod 24 through the handle 26 to drive the pressing plate 2 to rotate. When the pressing plate 2 rotates, it drives the roller sliding table 54 to slide along the guide rod 114 through the elastic traction rope 6 to compress the return spring 115. The roller sliding table 54 drives the upper sliding table 51 and the mounting frame 52 to move through the connecting frame 53. The mounting frame 52 drives the pressing roller 57 to move, so that the pressing roller 57 moves to the front end of the pressing plate 2 (such as Figure 10As shown in the figure), after the pressing plate 2 is pressed down, it clamps the paper sheet to be cut with the placing table 11, and then the pressing plate 22 cannot rotate continuously. When the pressing rod 24 rotates continuously, the connecting spring 25 is compressed, and the pressing rod 24 squeezes the stress rod 42. The second hinge frame 41 rotates to drive the ejector rod 43 to rise, lifting the tool holder 31 and driving the annular cutter 33 to rise to cut the paper sheet. After cutting, rotate the pressing plate 2 to return to its original position. After the stress rod 42 loses pressure, the ejector rod 43 descends under the gravity of the tool table 3, and the annular cutter 33 returns to its original position and enters the first knife groove 121. At the same time, the return spring 115 drives the roller sliding table 54 to slide back along the guide rod 114. The roller sliding table 54 drives the upper sliding table 51 and the mounting frame 52 to return to their original positions through the connecting frame 53, so that the pressing roller 57 returns to its original position to roll-press the cut cigarette paper, smooth the edges of the cigarette paper, and prevent the edges of the paper sheet from warping, which may affect the detection of the anti-bending ability of the paper sheet.
