Description

Technical Field

[0001] The invention belongs to the technical field of cigarette paper detection preprocessing equipment, and in particular relates to a cutting and shredding device for measuring safety indicators in cigarette paper. Background Art

[0002] In the tests of safety indicators in cigarette paper, including the test of phthalates and tributyl phosphate in cigarette paper (gas chromatography-mass spectrometry), the test of residual solvents in cigarette paper (headspace-gas chromatography-mass spectrometry), and the test of formaldehyde and acetaldehyde in cigarette paper (high performance liquid chromatography), it is necessary to cut the cigarette paper and cut specific parts of the cigarette paper into appropriate sizes. The test items also require the cut cigarette paper to be crushed into pieces of about 0.5cm×0.5cm, and then a certain amount of the pieces are taken for testing.

[0003] Among the cigarette papers that need to be cut, there are mainly three types as shown in the following table:

[0004] Paper material Location Size (cm) Strip wrapping paper Central area of ​​the front of the wrapper 22*5.5 Rigid box packaging paper Contains main packaging surface 22*5.5 Cigarette tipping paper Contains a single side 20*4

[0005] The above three types of cigarette papers that need to be cut have different shapes and sizes, and the positions and sizes that need to be cut are also different. Due to the lack of professional cutting tools, paper cutters are commonly used to cut cigarette papers. This results in the need to measure the cutting position before cutting the cigarette papers. When cutting, at least three cuttings are required to complete the process, which results in low efficiency and low precision.

[0006] Meanwhile, the existing shredding generally adopts a shredder, but it is necessary to cut the cigarette paper and then put the cut cigarette paper into the shredder manually, which is inconvenient to use. Summary of the invention

[0007] The purpose of the present invention is to provide a cutting and shredding device for measuring safety indicators in cigarette papers, which can efficiently and accurately cut three commonly used cigarette papers that need to be cut, and automatically put them into a shredder for shredding.

[0008] In order to achieve the above technical objectives, the technical solution adopted by the present invention is as follows:

[0009] A cutting and shredding device for measuring safety indicators in cigarette paper comprises a base and an inverted L-shaped support frame, wherein the base is provided with a first groove matching with an unfolded standard strip packaging paper, the base is provided with a second groove matching with an unfolded standard hard box packaging paper at the bottom of the first groove, the left side of the base is further provided with a third groove matching with cigarette tipping paper at the bottom of the second groove, the left side of the base is further provided with a through groove, a rectangular knife holder is provided above the base, a paper cutter in a rectangular frame is installed on the lower end surface of the rectangular knife holder, a rectangular avoidance groove matching with the paper cutter is provided on the base, a first lifting mechanism is fixedly installed on the inverted L-shaped support frame, a first mounting frame is connected to a free end of the first lifting mechanism, the first mounting frame is fixedly connected to the rectangular knife holder, a second mounting frame is fixedly installed on the rectangular knife holder at a position corresponding to the through groove, a second lifting mechanism is installed on the second mounting frame, a pressing member is installed at the free end of the second lifting mechanism, a shredder is further installed on the base below the through groove, and a containing frame is provided on the shredder.

[0010] It is further defined that both the first lifting mechanism and the second lifting mechanism are lifting hydraulic rods. Such a structural design is simple in structure and convenient in control.

[0011] It is further defined that the rectangular knife holder is provided with a plurality of ear plates on both sides of the paper cutter, the ear plates are provided with a first through hole, a connecting rod is slidably inserted into the first through hole, a limit block is fixedly installed on the upper end of the connecting rod above the ear plate, a pressing block is provided at the lower end of the connecting rod, and a magnet is embedded in the pressing block. With this structural design, the tobacco paper is pressed by the pressing block and the magnet, so as to avoid the dislocation of the tobacco paper during the cutting process, and further improve the cutting accuracy.

[0012] It is further defined that the connecting rod is sleeved with a second compression spring between the ear plate and the limit block. With this structural design, when the first lifting mechanism retracts, driving the rectangular tool holder to move upward and driving the pressure block to separate from the base, the second compression spring is used for buffering, thereby preventing the force borne by the first lifting mechanism from suddenly increasing, that is, the first lifting mechanism suddenly bears more force from the magnet adsorbed on the base, and effectively prolonging the service life of the first lifting mechanism.

[0013] It is further defined that the squeezing mechanism includes a third mounting frame, a pressure roller is mounted on the third mounting frame, a V-shaped paper feed port is provided on the shredder, a roller and a motor are also mounted on the shredder, a power output shaft of the motor is in transmission connection with the roller, and the roller is parallel to the pressure roller. With such a mechanism design, after the cutting of the cigarette paper is completed, the second lifting mechanism drives the squeezing mechanism to move downward, pressing the left end of the cut cigarette paper downward until the left end of the cut cigarette paper is squeezed together by the roller and the pressure roller, and then the motor is started to drive the roller to rotate, so that the cut cigarette paper enters the V-shaped paper feed port of the shredder, and is then crushed into pieces of about 0.5cm×0.5cm by the shredder.

[0014] It is further defined that the base is provided with a support roller in the through groove. With such a structural design, when the cut cigarette paper moves in the through groove under the action of the support roller, the support roller replaces the edge of the through groove to move relative to the cigarette paper, converting the sliding friction into rolling friction, reducing the friction force, and avoiding the problem of damage to the cigarette paper caused by excessive friction of the cut cigarette paper.

[0015] It is further defined that a rectangular auxiliary blade is fixedly installed in the avoidance groove, and the inner side surface of the rectangular auxiliary blade fits with the outer side surface of the paper cutter. With such a structural design, when the paper cutter cuts cigarette paper, the outer side surface of the paper cutter fits with the inner side surface of the rectangular auxiliary blade, and the cigarette paper is cut with more accurate cutting size.

[0016] It is further defined that the rectangular knife holder is provided with a plurality of ear plates on both sides of the paper cutter, the ear plates are provided with a first through hole, a connecting rod is slidably inserted into the first through hole, a limit block is fixedly installed on the upper end of the connecting rod above the ear plate, a pressing block is provided at the lower end of the connecting rod, and a first compression spring is sleeved between the ear plate and the pressing block. With such a structural design, the tobacco paper is pressed by the pressing block and the first compression spring, so as to avoid the dislocation of the tobacco paper during the cutting process, and further improve the cutting accuracy.

[0017] The invention adopting the above technical solution has the following advantages:

[0018] 1. Use three grooves to position the strip packaging paper, hard box packaging paper and cigarette tipping paper respectively, and then use the paper cutter to cut the cigarette paper. There is no need to measure the cigarette paper, which is highly efficient and accurate.

[0019] 2. The first lifting mechanism drives the paper cutter to move downward, cutting the cigarette paper at one time, realizing semi-automatic operation and further improving cutting efficiency;

[0020] 3. Pressing the tobacco paper with the first pressing block can prevent the tobacco paper from being misplaced during the cutting process, thereby further improving the cutting accuracy;

[0021] 4. The cut cigarette paper is automatically put into the shredder for crushing through the supporting roller, the pressure roller and the second lifting mechanism, which is more convenient to use. BRIEF DESCRIPTION OF THE DRAWINGS

[0038] In order to enable those skilled in the art to better understand the present invention, the technical solution of the present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0039] Embodiment 1:

[0040] like Figures 1 to 9 As shown, a cutting and shredding device for measuring safety indicators in cigarette paper of the present invention comprises a base 1 and an inverted L-shaped support frame 4, wherein a first groove 11 matching with an unfolded standard strip packaging paper 101 is provided on the base 1, a second groove 12 matching with an unfolded standard hard box packaging paper 102 is provided at the bottom of the first groove 11, a third groove 13 matching with cigarette tipping paper 103 is also provided laterally at the bottom of the second groove 12 on the left side of the base 1, a through groove 14 is also provided on the left side of the base 1, a rectangular knife holder 2 is provided above the base 1, and a rectangular knife holder 2 is installed on the lower end surface of the rectangular knife holder 2 The paper cutter 20 of the frame is provided with a rectangular avoidance groove 201 matching the paper cutter 20 on the base 1, a first lifting mechanism 41 is fixedly installed on the inverted L-shaped support frame 4, a first mounting frame 40 is connected to the free end of the first lifting mechanism 41, the first mounting frame 40 is fixedly connected to the rectangular knife holder 2, a second mounting frame 420 is fixedly installed on the rectangular knife holder 2 at a position corresponding to the through slot 14, a second lifting mechanism 42 is installed on the second mounting frame 420, an extrusion member is installed on the free end of the second lifting mechanism 42, a shredder 3 is also installed on the base 1 below the through slot 14, and a containing frame 30 is provided on the shredder 3.

[0041] The first lifting mechanism 41 and the second lifting mechanism 42 are both lifting hydraulic rods, which have a simple structure and are easy to control.

[0042] like Figure 3 and Figure 4 As shown, the rectangular knife holder 2 is provided with a plurality of ear plates 21 on both sides of the paper cutter 20, and a first through hole is opened on the ear plate 21, and a connecting rod 211 is slidably penetrated in the first through hole, and a limit block 212 is fixedly installed on the upper end of the connecting rod 211 above the ear plate 21, and a pressing block 213 is provided at the lower end of the connecting rod 211, and a magnet is embedded on the pressing block 213. The pressing block 213 and the magnet press the tobacco paper to avoid the dislocation of the tobacco paper during the cutting process, and further improve the cutting accuracy.

[0043] like Figure 3 and Figure 4 As shown, the connecting rod 211 is sleeved with a second compression spring 214 between the ear plate 21 and the limit block 212. When the first lifting mechanism 41 retracts, driving the rectangular tool holder 2 to move upward, driving the pressing block 213 to separate from the base 1, the second compression spring 214 is used for buffering to prevent the force borne by the first lifting mechanism 41 from suddenly increasing, that is, the first lifting mechanism 41 suddenly bears more force from the magnet adsorbed on the base 1, effectively extending the service life of the first lifting mechanism 41.

[0044] like Figure 5 and Figure 6 As shown, the squeezing mechanism includes a third mounting frame 421, on which a pressing roller 4210 is mounted, a V-shaped paper inlet 31 is provided on the shredder 3, and a roller 32 and a motor 33 are also mounted on the shredder 3, the power output shaft of the motor 33 is in transmission connection with the roller 32, and the roller 32 is parallel to the pressing roller 4210. With such a mechanism design, after the cigarette paper is cut, the second lifting mechanism 42 drives the squeezing mechanism to move downward, and presses the left end of the cut cigarette paper 104 downward until the left end of the cut cigarette paper 104 is squeezed together by the roller 32 and the pressing roller 4210, and then the motor 33 is started, and the motor 33 drives the roller 32 to rotate, so that the cut cigarette paper 104 enters the V-shaped paper inlet 31 of the shredder 3, and is then crushed into pieces of about 0.5 cm×0.5 cm by the shredder 3.

[0045] like Figure 2 As shown, the base 1 is provided with a support roller 34 in the through groove 14. When the cut cigarette paper 104 moves in the through groove 14 under the action of the support roller 32, the support roller 34 replaces the edge of the through groove 14 to move relative to the cigarette paper 104, converting the sliding friction into rolling friction, reducing the friction force, and avoiding the problem of damage to the cigarette paper 104 caused by excessive friction of the cut cigarette paper 104.

[0046] A rectangular auxiliary blade is fixedly installed in the avoidance groove 201, and the inner side of the rectangular auxiliary blade fits the outer side of the paper cutter 20. When the paper cutter 20 cuts cigarette paper, the outer side of the paper cutter 20 fits the inner side of the rectangular auxiliary blade, and the cigarette paper is cut, and the cutting size is more accurate.

[0047] The paper cutter 20 includes four blades, front, back, left, and right, which are arranged end to end in a rectangular shape. The distance between the outer sides of the left and right blades is 22 cm, and the distance between the outer sides of the front and back blades is 5.5 cm, which corresponds to the cutting size and position of strip packaging paper and hard box packaging paper.

[0048] The avoidance groove 201 corresponds to the position of the paper cutter 20;

[0049] The distance between the right end surface of the third groove 13 and the left end surface of the blade on the left side is 20 cm, which is consistent with the cutting length of the cigarette tipping paper 103;

[0050] The distance between the rear end surface of the third groove 13 and the front end surface of the front blade is 4 cm, which is consistent with the cutting width of the cigarette tipping paper 103 .

[0051] In this embodiment, when cutting the strip packaging paper (such as Figure 7 As shown in the figure, the unfolded standard strip packaging paper 101 is placed into the first groove 11, so that the edge of the unfolded standard strip packaging paper 101 coincides with the edge of the first groove 11, the first lifting mechanism 41 drives the mounting frame 40 to move downward, and then drives the rectangular knife holder 2 to move downward until the pressing block 213 approaches the base 1, and the unfolded standard strip packaging paper 101 is pressed on the base 1, the first lifting mechanism 41 continues to drive the mounting frame 40 to continue to move downward, and the paper cutter 20 is used to cut the unfolded standard strip packaging paper 101;

[0052] Repeat the above steps, and then cut the unfolded standard hard box packaging paper 102 and the cigarette tipping paper 103 respectively, and put the unfolded standard hard box packaging paper 102 into the second groove 12 (such as Figure 8 As shown), the unfolded standard hard box packaging paper 102 overlaps with the edge of the second groove 12; the cigarette tipping paper 103 is placed into the third groove 13 from the left side of the base 1 (as shown Fig. 9 As shown), the edges of the cigarette tipping paper 103 are respectively against the front side wall, the rear side wall and the right side wall of the third groove 13;

[0053] After the cutting is completed, the first lifting mechanism 41 drives the mounting frame 40 to move upward for a certain distance, drives the paper cutter 20 and the pressing block 213 to move upward and separate from the base 1, and then starts the second lifting mechanism 42, so that the squeezing member moves downward, drives the left end of the cut cigarette paper 104 to enter the through groove 14, and the left end of the cut cigarette paper 104 is pressed down by the squeezing member until it is fixed by the pressing roller 423 and the receiving roller 361, and at the same time corresponds to the position of the strip through groove 334 of the rolling rod 333;

[0054] The second lifting mechanism 42 drives the pressing mechanism to move downward, pressing the left end of the cut cigarette paper 104 downward until the left end of the cut cigarette paper 104 is pressed together by the support roller 32 and the pressing roller 4210, and then the motor 33 is started, and the motor 33 drives the support roller 32 to rotate, so that the cut cigarette paper 104 enters the V-shaped paper inlet 31 of the shredder 3, and is then shredded by the shredder 3 into pieces of about 0.5 cm×0.5 cm (such as Figure 5 and Figure 6 shown);

[0055] Finally, the first lifting mechanism 41 and the second lifting mechanism 42 drive the rectangular knife holder 2 and the extrusion member to return to the initial position, and then the containing frame 30 is removed from the shredder 3, and the shredded cigarette paper in the containing frame 30 can be taken out.

[0056] Embodiment 2:

[0057] The rectangular knife holder 2 is provided with a plurality of ear plates 21 on both sides of the paper cutter 20. A first through hole is opened on the ear plate 21. A connecting rod 211 is slidably inserted into the first through hole. A limit block 212 is fixedly installed above the ear plate 21 at the upper end of the connecting rod 211. A pressure block 213 is provided at the lower end of the connecting rod 211. A first compression spring is sleeved between the ear plate 21 and the pressure block 213 of the connecting rod 211.

[0058] Such a structural design presses the tobacco paper through the pressing block 213 and the first compression spring, thereby preventing the tobacco paper from being misplaced during the cutting process, and further improving the cutting accuracy.
