Description

Technical Field

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

[0002] In experiments such as the determination of safety indicators in cigarette paper, including the determination of phthalates and tributyl phosphate in cigarette paper (gas chromatography-mass spectrometry), the determination of solvent residues in cigarette paper (headspace-gas chromatography-mass spectrometry), and the determination 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.

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

[0004] Paper material Location Size (cm) Strip wrapping paper Central area on 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 Cigarette lining paper Contains a single side 17*10

[0005] The above four 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, resulting in low efficiency and low precision. Summary of the invention

[0006] The purpose of the present invention is to provide a semi-automatic cutting device for measuring safety indicators in cigarette papers, which can efficiently and accurately cut four commonly used cigarette papers that need to be cut.

[0007] In order to achieve the above technical objectives, the technical solution adopted by the present invention is as follows:

[0008] A semi-automatic cutting device for measuring safety indicators in cigarette paper comprises a base, a mounting frame and a supporting 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 base is also provided with a third groove and a fourth groove longitudinally at the bottom of the first groove, the base is also provided with a front transverse groove, a rear transverse groove, a left longitudinal groove and a right longitudinal groove, the rear transverse groove and the right longitudinal groove are connected to form a C-shape, and the front transverse groove, the rear transverse groove, the left longitudinal ... The mounting bracket is located above the base, and paper cutters are fixedly installed on the mounting bracket at corresponding positions of the front transverse groove, the rear transverse groove, the left longitudinal groove and the right longitudinal groove. A plurality of ear plates are fixedly provided on the mounting bracket on both sides of the paper cutter, and a first through hole is provided on the ear plate, and a first connecting rod is slidably penetrated in the first through hole. A first limiting block is fixedly installed on the upper end of the first connecting rod above the ear plate, and a first pressing block is provided at the lower end of the first connecting rod, and a magnet is embedded on the first pressing block. The supporting bracket is located above the mounting bracket and is fixedly connected to the base, and a telescopic hydraulic rod is fixedly installed between the supporting bracket and the mounting bracket.

[0009] It is further defined that a rubber pad is fixedly mounted on the lower end surface of the first pressing block. With such a structural design, the first pressing block contacts various cigarette papers through the rubber pad, and the rubber pad itself has a certain elasticity, which can prevent the first pressing block from causing damage to the cigarette paper when squeezing and fixing the cigarette paper.

[0010] It is further defined that the upper end of the telescopic hydraulic rod is connected to the support frame, and the lower end is fixedly connected with a second pressure block, the lower end surface of the second pressure block is fixedly connected with a second connecting rod, the lower end of the second connecting rod is fixedly connected with a second limit block, the mounting frame is provided with a second through hole matching the second connecting rod, and the second connecting rod is sleeved with a second compression spring between the mounting frame and the second limit block. With such a structural design, when the telescopic hydraulic rod retracts and drives the mounting frame to move upward, the second compression spring is used for buffering, so as to avoid a sudden increase in the force borne by the telescopic hydraulic rod, that is, the telescopic hydraulic rod suddenly bears more gravity of the mounting frame, and effectively prolongs the service life of the telescopic hydraulic rod.

[0011] It is further defined that the second connecting rod is sleeved with a third compression spring between the mounting frame and the second pressure block. With this structural design, when the telescopic hydraulic rod is extended to drive the paper cutter to move downward to cut the tobacco paper, the third compression spring is used to provide a buffer between the second pressure block and the mounting frame to avoid a sudden increase in the force borne by the telescopic hydraulic rod, thereby extending the service life of the telescopic hydraulic rod.

[0012] It is further defined that the first connecting rod is sleeved with a first compression spring between the ear plate and the first limit block. With such a structural design, when the telescopic hydraulic rod retracts, driving the mounting frame to move upward and driving the first pressure block to separate from the base, the first compression spring is used for buffering, thereby preventing the force borne by the telescopic hydraulic rod from suddenly increasing, that is, the telescopic hydraulic rod suddenly bears more force from the magnet adsorbed on the base, thereby extending the service life of the telescopic hydraulic rod.

[0013] It is further defined that a plurality of sliding shafts are fixedly mounted on the mounting frame, and a sliding sleeve is fixedly provided on the support frame at a position corresponding to the sliding shaft, and the sliding shaft is inserted into the sliding sleeve. Such a structural design limits the freedom of the mounting frame except the vertical direction through the mutual cooperation between the sliding shaft and the sliding sleeve, so that the mounting frame can maintain balance, reduce the radial pressure on the telescopic hydraulic rod, and extend the service life of the telescopic hydraulic rod.

[0014] It is further defined that a linear bearing is installed between the sliding shaft and the sliding sleeve. Such a structural design can reduce the friction between the sliding shaft and the sliding sleeve, making the sliding between the sliding shaft and the sliding sleeve smoother and more practical.

[0015] It is further defined that the third groove and the fourth groove are both connected to the front end surface of the base. With such a structural design, when cutting the cigarette tipping paper and the cigarette lining paper, the cigarette tipping paper and the cigarette lining paper can be pushed into the corresponding grooves from the front end of the base, which is more convenient to use.

[0016] It is further defined that the support frame includes a top plate and three support arms, and the top plate is L-shaped. With such a structural design, the L-shaped top plate matches the shape of the mounting frame, providing a more stable support for the mounting frame.

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

[0018] 1. Use four grooves to position the strip packaging paper, hard box packaging paper, cigarette tipping paper and cigarette lining 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 telescopic hydraulic rod 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. The tobacco paper is pressed by pressing the first pressing block and the magnet to avoid dislocation of the tobacco paper during the cutting process, thereby further improving the cutting accuracy. BRIEF DESCRIPTION OF THE DRAWINGS

[0037] 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.

[0038] like Figures 1 to 8 As shown, a semi-automatic cutting device for measuring safety indicators in cigarette paper of the present invention comprises a base 1, a mounting frame 31 and a supporting frame, wherein the base 1 is provided with a first groove 11 matching with an unfolded standard strip packaging paper 101, the base 1 is provided with a second groove 12 matching with an unfolded standard hard box packaging paper 102 at the bottom of the first groove 11, the base 1 is also provided with a third groove 13 and a fourth groove 14 longitudinally at the bottom of the first groove 11, the base 1 is also provided with a front transverse groove 21, a rear transverse groove 22, a left longitudinal groove 23 and a right longitudinal groove 24, the rear transverse groove 22 and the right longitudinal groove 24 are connected to form a C-shape, and the front transverse groove 21, the rear transverse groove 22, the left longitudinal groove 23 and the right longitudinal groove 24 are connected to each other.

[0039] The mounting frame 31 is located above the base 1, and a paper cutter 32 is fixedly installed on the mounting frame 31 at the corresponding positions of the front transverse groove 21, the rear transverse groove 22, the left longitudinal groove 23 and the right longitudinal groove 24. A plurality of ear plates 33 are fixedly provided on the mounting frame 31 on both sides of the paper cutter 32, and a first through hole is opened on the ear plate 33. A first connecting rod 331 is slidably penetrated in the first through hole. A first limiting block 332 is fixedly installed on the upper end of the first connecting rod 331 above the ear plate 33, and a first pressing block 333 is provided at the lower end of the first connecting rod 331. A magnet is embedded on the first pressing block 333. The support frame is located above the mounting frame 31 and is fixedly connected to the base 1. A telescopic hydraulic rod 4 is fixedly installed between the support frame and the mounting frame 31.

[0040] A rubber pad is also fixedly mounted on the lower end surface of the first pressing block 333. The first pressing block 333 contacts various cigarette papers through the rubber pad, and the rubber pad itself has a certain elasticity, which can prevent the first pressing block 333 from causing damage to the cigarette paper when squeezing and fixing the cigarette paper.

[0041] The upper end of the telescopic hydraulic rod 4 is connected to the support frame, and the lower end is fixedly connected to a second pressing block 41. The lower end surface of the second pressing block 41 is fixedly connected to a second connecting rod 411. The lower end of the second connecting rod 411 is fixedly connected to a second limit block 412. The mounting frame 31 is provided with a second through hole 40 matching the second connecting rod 411. The second connecting rod 411 is sleeved with a second compression spring 410 between the mounting frame 31 and the second limit block 412. When the telescopic hydraulic rod 4 retracts and drives the mounting frame 3 to move upward, the second compression spring 410 is provided on the mounting frame 31.

[0042] The second compression spring 410 performs buffering to prevent the force on the telescopic hydraulic rod 4 from suddenly increasing, that is, the telescopic hydraulic rod 4 suddenly bears more gravity of the mounting frame 31 , thereby effectively extending the service life of the telescopic hydraulic rod 4 .

[0043] The second connecting rod 411 is sleeved with a third compression spring 413 between the mounting frame 31 and the second pressing block 41. When the telescopic hydraulic rod 4 is extended to drive the paper cutter 32 to move downward to cut the tobacco paper, the third compression spring 413 is used to provide a buffer between the second pressing block 41 and the mounting frame 31 to prevent the force on the telescopic hydraulic rod 4 from increasing suddenly, thereby extending the service life of the telescopic hydraulic rod 4.

[0044] The first connecting rod 331 is sleeved with a first compression spring between the ear plate 33 and the first limit block 332. When the telescopic hydraulic rod 4 retracts, driving the mounting frame 3 to move upward and driving the first pressure block 333 to separate from the base 1, the first compression spring is used for buffering to prevent the force on the telescopic hydraulic rod 4 from suddenly increasing, that is, the telescopic hydraulic rod 4 suddenly bears more force from the magnet adsorbed on the base 1, thereby extending the service life of the telescopic hydraulic rod 4.

[0045] A plurality of sliding shafts 34 are fixedly mounted on the mounting frame 31, and a sliding sleeve 35 is fixedly mounted on the supporting frame at a position corresponding to the sliding shaft 34, and the sliding shaft 34 is inserted into the sliding sleeve 35. Through the cooperation between the sliding shaft 34 and the sliding sleeve 35, the freedom of the mounting frame 31 except the vertical direction is limited, so that the mounting frame 31 can maintain balance, reduce the radial pressure on the telescopic hydraulic rod 4, and extend the service life of the telescopic hydraulic rod 4.

[0046] A linear bearing is installed between the sliding shaft 34 and the sliding sleeve 35. The friction between the sliding shaft 34 and the sliding sleeve 35 can be reduced, so that the sliding between the sliding shaft 34 and the sliding sleeve 35 is smoother and more practical.

[0047] The third groove 13 and the fourth groove 14 are both connected to the front end surface of the base 1. When cutting the cigarette tipping paper 103 and the cigarette lining paper 104, the cigarette tipping paper 103 and the cigarette lining paper 104 can be pushed into the corresponding grooves from the front end of the base 1, which is more convenient to use.

[0048] The support frame includes a top plate 51 and three support arms 52, and the top plate 51 is L-shaped. The L-shaped top plate 51 matches the shape of the mounting frame 31, and supports the mounting frame 31 more stably.

[0049] The distance between the front transverse groove 21 and the rear transverse groove 22 is 5.5 cm, which is consistent with the cutting width of the strip packaging paper and the hard box packaging paper;

[0050] The distance between the left longitudinal groove 23 and the right longitudinal groove 24 is 22 cm, which is consistent with the cutting length of the strip packaging paper and the hard box packaging paper;

[0051] The distance between the right end face of the third groove 13 and the right longitudinal groove 24 is 4 cm, which is consistent with the cutting width of the cigarette tipping paper 103. The distance between the right end face of the fourth groove 14 and the right longitudinal groove 24 is 10 cm, which is consistent with the cutting width of the cigarette lining paper 104.

[0052] The distance between the front end surface of the third groove 13 and the rear transverse groove 22 is 20 cm, which is consistent with the cutting length of the cigarette tipping paper 103 . The distance between the front end surface of the fourth groove 14 and the rear transverse groove 22 is 17 cm, which is consistent with the cutting length of the cigarette lining paper 104 .

[0053] In this embodiment, when cutting the strip packaging paper (such as Figure 5 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, and the telescopic hydraulic rod 4 is started to drive the mounting frame 31 to move downward until the first pressing block 333 approaches the base 1. At this time, the first pressing block 333 moves downward under the action of the magnet to overcome the pressure of the first compression spring, and presses the unfolded standard strip packaging paper 101 on the base 1. The telescopic hydraulic rod 4 continues to extend, driving the mounting frame 31 to continue to move downward until the paper cutter 32 contacts the unfolded standard strip packaging paper 101, and the telescopic hydraulic rod 4 continues to extend, and the mounting frame 31 is squeezed by the second pressing block 41, so that the unfolded standard strip packaging paper 101 is cut by the paper cutter 32;

[0054] After the cutting is completed, the telescopic hydraulic cylinder 4 retracts, driving the mounting frame 31 to move upward, driving the paper cutter 32 and the first pressing block 333 to move upward and separate from the base 1. At this time, the cut cigarette paper can be removed from the base 1.

[0055] Similarly, when cutting the unfolded standard hard box packaging paper 102 (such as Figure 6As shown), put the unfolded standard hard box packaging paper 102 into the second groove 12, so that the unfolded standard hard box packaging paper 102 is in contact with the front end surface, left end surface and right end surface of the second groove 12, and then start the telescopic hydraulic rod 4 to cut;

[0056] When the cigarette tipping paper 103 is cut (such as Figure 7 As shown), put the cigarette tipping paper 103 from the front end of the base 1 into the third groove 13, so that the upper right corner of the cigarette tipping paper 103 is against the upper right corner of the third groove 13, the cigarette tipping paper 103 is positioned, and then the telescopic hydraulic rod 4 is started to cut;

[0057] When the cigarette liner paper 104 is cut (such as Figure 8 As shown), place the cigarette liner paper 104 in the fourth groove 14 so that the upper right corner of the cigarette liner paper 104 is against the upper right corner of the fourth groove 14, completing the positioning of the cigarette liner paper 104, and then start the telescopic hydraulic rod 4 to cut.

[0058] The above is a detailed introduction to a semi-automatic cutting device for measuring safety indicators in cigarette paper provided by the present invention. The description of the specific embodiment is only used to help understand the method and core idea of ​​the present invention.
