Description

Technical Field

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

[0002] Cigarette box wrapping paper refers to paper-based decorative printed materials used to wrap cigarettes, and cigarette strip wrapping paper refers to paper-based decorative printed materials used to wrap a certain number of cigarette boxes. Cigarette strip and box wrapping paper are mainly used to protect cigarettes during market circulation, facilitate storage and transportation, and can display and beautify cigarette brands. They are an indispensable and important part of cigarette production.

[0003] In the early days of cigarette packaging, it was mainly a measure taken to protect cigarettes and facilitate transportation. After a long evolution, various packaging methods in different eras, fields and forms have formed their own unique cultural heritage. Today's cigarette packaging not only integrates philosophy, sociology, psychology, linguistics, and history, but also comprehensively reflects knowledge of religion, customs, etc., and even integrates social and cultural connotations, enriches the development of regional culture, and realizes the inheritance of historical culture.

[0004] 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 tool 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, the tool of the current cutting device is external, and the staff is prone to contact with the tool when placing or taking the cigarette paper, which poses a great safety hazard. Summary of the invention

[0005] Based on the problems mentioned in the above background technology, the present invention provides a cigarette paper cutting and flattening device, which is used to solve the problem that when cutting packaging paper, 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.

[0006] The technical solution adopted by the present invention is as follows:

[0007] A cigarette paper cutting and flattening device comprises a placing table, wherein a base is integrally formed at the bottom of the placing table, a mold table is arranged in the middle of the placing table, a fixing column is installed at the bottom end of the mold table, a first knife groove is arranged between the placing table and the mold table, a transverse plate is installed on the base, the fixing column is installed on the transverse plate, a pressing plate and a lifting frame are hingedly installed on the placing table, a first hinge frame is integrally formed on the pressing plate, the pressing plate is hinged to the mold table through the first hinge frame, the lifting frame is located above one end of the lower part of the mold table and a knife table is arranged, the knife table comprises a knife seat and an annular cutter, and the annular cutter is installed on At the top of the knife seat, the annular cutter is located in the first knife groove, a reserved groove is provided on the knife seat, the fixed column is located in the reserved groove, a second knife groove corresponding to the first knife groove is provided on the pressure plate, a hinge seat is provided on the pressure plate, a pressure rod is hinged on the hinge seat, a first spring is installed between the pressure rod and the pressure plate, the lifting frame includes a fixedly connected force rod, a second hinge frame and a push rod, the second hinge frame is hinged on the mold platform, the push rod is in sliding contact with the bottom end of the knife seat, and a rotating flattening mechanism is installed on the placement platform, and the rotating flattening mechanism is located on one side of the pressure plate.

[0008] On the basis of the above scheme, the present invention also makes the following improvements:

[0009] Furthermore, the top of the mold platform is provided with a first hinge groove extending vertically downward, and the bottom of the mold platform is provided with a second hinge groove extending vertically upward. 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.

[0010] Furthermore, the inner wall of the annular cutter fits the outer wall of the die plate, thereby reducing the gap between the blade area of ​​the annular cutter and the outer wall of the die plate during cutting, making the cut of the paper sheet more neat and preventing the edge of the paper sheet from being greatly warped after cutting.

[0011] Furthermore, 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.

[0012] Furthermore, a first limiting column is installed at the top of the knife seat, a blind hole corresponding to the first limiting column is opened at the bottom of the placement table, and the first limiting column is inserted into the blind hole. The movement of the knife seat is guided by the first limiting column to prevent the knife seat from tilting during movement and causing damage to the annular cutter.

[0013] Further, the rotary flattening mechanism includes a first mounting frame installed on the placement table, a rotating shaft is slidably provided on the first mounting frame, a first bevel gear is installed on the rotating shaft, a second mounting frame is installed on the bottom end of the rotating shaft, a pressure roller is installed on the second mounting frame, a pull rod seat is installed on the first mounting frame, a pull rod is hinged on the pull rod seat, a first U-shaped frame is sleeved on the pull rod, a sleeve is installed at the bottom end of the first U-shaped frame, a second spring is installed between the sleeve and the pull rod, the second spring is located in the first U-shaped frame, a bearing is installed in the sleeve, and the bearing is sleeved on the top end of the rotating shaft. The first mounting frame is provided with a bearing seat, a transmission shaft is provided in the bearing seat, a transmission gear and a second bevel gear are provided at both ends of the transmission shaft, and the second bevel gear meshes with the first bevel gear when the pressure roller contacts the placement table, a second U-shaped frame is provided on the first mounting frame for sliding, an ear plate is provided on the second U-shaped frame, a second limiting column is provided on the ear plate, the second limiting column is provided on the first mounting frame, a third spring is sleeved on the second limiting column, the third spring is located between the ear plate and the first mounting frame, a rack is provided on the second U-shaped frame, and the rack meshes with the transmission gear. The second spring is squeezed by rotating the pull rod to drive the rotating shaft and the pressure roller to descend. Since the pressure roller cannot continue to descend after contacting the placement table, the pull rod can be continuously rotated to squeeze the second U-shaped frame. The descent of the second U-shaped frame drives the transmission gear to rotate. Under the action of the second bevel gear and the first bevel gear, the rotating shaft can be driven to rotate, and then the pressure roller is driven to rotate to squeeze the paper placed on the placement table, so as to smooth the edge of the paper after cutting and avoid the edge of the paper from warping up and affecting the detection result.

[0014] Furthermore, the bearing is a double-row tapered roller bearing, which has a strong axial load-bearing capacity.

[0015] Furthermore, a handle is provided at the bottom end of the pressure rod, and the pressure rod can be easily rotated by the handle, so that it is convenient to use.

[0016] Beneficial effects of the present invention:

[0017] 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, driving 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 paper sheet more neat, avoiding the edge of the paper sheet from being greatly warped after cutting, resulting in an enhanced anti-bending ability of the paper sheet, and reducing the impact on the detection result;

[0018] 2. By setting up a rotary flattening mechanism, the cut paper can be moved to the lower part of the rotary flattening mechanism after sampling is completed, and the edge of the sample paper can be smoothed by the rotary flattening mechanism to avoid the edge of the sample paper from warping up due to cutting and squeezing, which may affect the test results;

[0019] 3. After the pressure plate is lifted, the circular cutter will automatically retract into the first cutter groove under the gravity of the knife table. The staff will not come into contact with the circular cutter when placing or taking paper sheets, which is safer. BRIEF DESCRIPTION OF THE DRAWINGS

A bearing seat 511 is installed on a mounting frame 51, and a transmission shaft is passed through the bearing seat 511. A transmission gear 591 and a second bevel gear 592 are respectively installed at both ends of the transmission shaft. When the pressure roller 531 contacts the placement table 11, the second bevel gear 592 meshes with the first bevel gear 593. A second U-shaped frame 57 is slidably passed through the first mounting frame 51, and an ear plate 571 is provided on the second U-shaped frame 57.

A rack 574 is provided on the second U-shaped frame 57, and the rack 574 meshes with the transmission gear 591. The second spring 545 is squeezed by rotating the pull rod 582 to drive the rotating shaft 52 and the pressure roller 531 to descend. Since the pressure roller 531 cannot continue to descend after contacting the placement table 11, the pull rod 582 is continued to be rotated to squeeze the second U-shaped frame 57. The second U-shaped frame 57 descends and drives the transmission gear 591 to rotate. Under the action of the second bevel gear 592 and the first bevel gear 593, the rotating shaft 52 can be driven to rotate, and then the pressure roller 531 can be driven to rotate to squeeze the paper placed on the placement table 11, so as to smooth the edges of the cut paper and prevent the edges of the paper from warping up and affecting the detection results.

[0039] Specifically, the bearing 55 is a double-row tapered roller bearing, which has a strong axial load-bearing capacity.

[0041] When using the paper for cutting, 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 24 is pulled by the handle 26 to drive the pressing plate 2 to rotate. After the pressing plate 2 and the placement table 11 clamp the paper to be cut, the pressing plate 22 cannot continue to rotate. Continue to rotate the pressure rod 24, the first spring 25 compresses the pressure rod 24 and squeezes the force-bearing rod 42. The second hinged frame 41 rotates to drive the push rod 43 to rise, lift the knife seat 31, and drive the annular cutter 33 to rise and cut the paper.

[0042] After the cutting is completed, the pressing plate 2 is rotated back to its original position. After the force-bearing rod 42 loses its pressure, the push rod 43 descends under the gravity of the knife platform 3, and the annular cutter 33 returns to its original position and enters the first knife groove 121. Then, the cut paper piece is placed under the pressing roller 531, and the pull rod 582 is rotated to squeeze the second spring 545 to push the rotating shaft 52 down. When the pressing roller 531 contacts the paper piece, the pressing roller 531 will not be able to move downward further under the action of the placing platform 11. At this time, the first bevel gear 593 and the second bevel gear 59 2 is engaged, and when the pull rod 582 is continuously pressed, the second spring 545 contracts the pull rod 582 to squeeze the second U-shaped frame 57 to make the second U-shaped frame 57 descend, and the second U-shaped frame 57 drives the rack 574 to descend, so that the rack 574 drives the transmission gear 591 to rotate, and the transmission gear 591 drives the first bevel gear 593 to rotate through the second bevel gear 592, and the rotating shaft 52 rotates synchronously to drive the pressing roller 531 to rotate and smooth the edge of the paper sheet, so as to prevent the edge of the paper sheet from warping and affecting the detection of the anti-bending ability of the paper sheet.
