[0013] 1. The set pressing mechanism can move synchronously with the cutting position, closely fit the cardboard to prevent the cardboard from warping, burrs or adhesion during cutting. The cutting angle of the cutting knife can be stably adjusted for cardboards of different hardness and thickness to achieve the best cutting effect. The inclination angle of the cutting knife can be accurately adjusted through the indicator. The pressing mechanism is not affected by the inclination angle and can stably press the bottom cardboard.

[0014] 2. This device not only ensures the quality and efficiency of cutting, but also takes into account the durability of the cutter and the flatness of the cutting surface during the cutting process. According to factors such as the cutting resistance of the cut cardboard and the cutting speed of the cutter, the cutter angle is properly adjusted to ensure the best cutting effect;

[0015] 3. This device can be used for packaging cigarette box cardboards of different sizes. When using an oblique knife for cutting, the knife angle can be flexibly adjusted according to the size to be cut. After cutting, the clamping force of the clamping part on the cardboard can be controlled, and no obvious indentation will appear. The effect of pulling the cardboard apart after cutting can ensure that the thickness of the cutter itself will not squeeze the edge of the cardboard, eliminating the problem of the cut edge being squeezed and warped.

DETAILED DESCRIPTION

[0031] The present invention is described in detail below, and the technical solutions in the embodiments of the present invention are clearly and completely described. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] Reference Figure 1-Figure 12As shown, a paper packaging cigarette box cutting device includes a support plate 2, two side plates 3, an electric telescopic rod 6, a support arm 24 and a cutting blade 5. The two side plates 3 are fixed to the top of the support plate 2. The side wall of each side plate 3 close to each other is provided with two symmetrical sliding grooves 32 and a receiving groove 14. A support block 7 is fixed to the outer wall of the top of one of the side plates 3 by screws. The electric telescopic rod 6 is fixed to the support block 7. The output shaft 12 of the electric telescopic rod 6 is fixed to the top of the support arm 24. A passive groove 25 is provided at the bottom of the support arm 24. The passive groove 25 is slidably connected with a passive suspension rod 16. The support arm 24 is threadedly plugged with a threaded rod 4. The bottom of the threaded rod 4 is integrally formed with a connecting suspension rod 41. The passive suspension rod 16 and the connecting suspension rod 41 are connected to the cutting blade through a movable shaft 26. The plate 5 is rotatably connected, and two movable tracks 18 are movably sleeved between the two movable shafts 26. The two movable tracks 18 are respectively located on both sides of the cutting blade plate 5, and a pressing mechanism is movably arranged on each movable track 18. Two fixing plates 13 are provided on both sides of the support arm 24, and a cross bar 19 is fixed between the two fixing plates 13 on the same side. Each cross bar 19 slides between two corresponding sliding grooves 32 respectively, and a longitudinal rod 15 is slidably connected in each accommodating groove 14. A flat pressing transmission is provided above the four longitudinal rods 15. The bottom of every two longitudinal rods 15 located on the same side of the cutting blade plate 5 is welded with the same pressing plate 8, and the two pressing plates 8 are symmetrically distributed on both sides of the cutting blade plate 5, and a film plate 28 is fixed to one side wall where the two pressing plates 8 are close to each other.

[0033] The pressing mechanism includes a driving shaft 36, a finger press 29 and a pressing wheel 27. The driving shaft 36 is located in the corresponding movable track 18 and slides. The finger press 29 is respectively provided with a wire receiving groove 290 and a limit groove 292, and the wire receiving groove 290 and the limit groove 292 are connected. A receiving movable groove rail 351 is slidably connected in the wire receiving groove 290, and a limit adjustment block 35 is fixed at the bottom of the receiving movable groove rail 351. The outer wall of the driving shaft 36 is movably sleeved with a passive solid block 37. A limit spring 57 is connected between the passive solid block 37 and the limit adjustment block 35, and the passive solid block 37 The limit adjustment block 35 and the limit adjustment block 35 are both located in the limit groove 292 and slide. The internal sliding connection of the movable groove rail 351 is provided with a locking plate 40. The locking plate 40 is in close contact with the upper part of the outer peripheral wall of the active shaft 36. The outer wall of the finger press 29 close to the cutting blade 5 is provided with a retention groove 291. The inner side of the retention groove 291 is slidably connected with a connecting column 42. The outer wall of one side of the connecting column 42 is rotatably connected with a pressing wheel 27. The overall gravity of the pressing wheel 27 is higher than that of other parts and connecting parts of the pressing mechanism. The top of the connecting column 42 is integrally formed with a plate 42. 1. The outer wall of the finger press 29 near the cutting blade 5 is slidably connected with a sleeve rail 34, which is sleeved on the driving shaft 36. The sleeve rail 34 is provided with a track sleeve hole 340. The upper hole diameter of the track sleeve hole 340 is smaller than the lower part, so that when the track sleeve hole 340 is sleeved on the inner rolling part 361 of the driving shaft 36, the upper part of the track sleeve hole 340 can increase the rotation resistance of the inner rolling part 361 of the shaft to prevent it from rotating, so that the entire pressing mechanism will not move. The bottom outer wall of the sleeve rail 34 and the abutment sheet The tops of the plates 421 are in contact, and a winding shaft 39 is movably inserted into the outer wall of the side of the finger press 29 away from the cutting blade plate 5. The outer walls of the winding shaft 39 are respectively fixedly sleeved with a gradually rising plate 31 and a turning handle 30. The gradually rising plate 31 is in contact with the limit adjustment block 35. The winding shaft 39 passes through the finger press 29 to the wire receiving groove 290. High-strength wires 38 are fixed at both ends of the bottom of the locking plate 40, and the two high-strength wires 38 are wound around the bottom of the limit adjustment block 35 and connected to each other. After the two high-strength wires 38 are connected, they become one high-strength wire 38 and are wound around the winding shaft 39.

[0034] Among them, reference Figure 5-Figure 7 As shown, the driving shaft 36 is specifically arranged such that the outer end is inserted into the passive solid block 37, and the middle part is a part with high friction resistance, so that when the locking plate 40 is in close contact, the driving shaft 36 will not rotate, and the inner end is an inner rolling part 361 of the shaft, which is rotatably arranged in the movable track 18, and a passive ring 362 can be fixedly sleeved on the outside of the inner rolling part 361 of the shaft to roll synchronously with it in the groove of the movable track 18, and the entire driving shaft 36 can rotate and move in the movable track 18 without the action of external force.

[0035] Regarding the pressing mechanism, it should be noted that initially, the pressing wheel 27 contacts the bottom film plate 28 by its own weight, and when the cutting blade 5 cuts downward, the movable track 18 moves with it and drives the finger press 29 to move downward. Fig.11 The initial upper gap of the retention groove 291 is reduced until it starts to press the connecting column 42, thereby resisting the upward movement of the sleeve-type clamping rail 34. The upper part of the rail sleeve hole 340 no longer blocks the rotation of the active shaft 36. When the cutting blade 5 continues to cut downward, the movable track 18 continues to move with it and squeezes the limit spring 57 through the passive solid block 37. At this time, the taut high-strength wire 38 no longer makes the upper locking plate 40 close to the middle part of the active shaft 36. The active shaft 36 releases all external force restrictions and can roll with the inner track of the movable track 18 to drive the entire pressing mechanism to move with the cutting position of the cardboard 10. During the movement, the bottom pressure wheel 27 also always presses the film plate 28.

[0036] It should be further explained that the setting of the gradually rising plate 31 is that before cutting, the handle 30 is rotated to make the gradually rising plate 31 rotate to contact the limit adjustment block 35 at the same time, the limit spring 57 is shortened, and the winding shaft 39 is rotated to store the high-strength wire 38. Specifically, the limit adjustment block 35 moves up and the movable groove rail 351 also moves. However, in order to ensure that the locking plate 40 can always remain close to the middle part of the active shaft 36, it is necessary to pull down the high-strength wire 38 to keep it in a braking state, so that the initial compression force of the limit spring 57 is increased at this time, which is used to press the cardboard 10 with higher hardness, and the pressing force can be flexibly adjusted by adjusting the gradually rising plate 31 to contact the limit adjustment block 35.

[0037] The flat-pressure transmission device includes a fixed sleeve column 45 and a passive card 44. The fixed sleeve column 45 is fixedly inserted in the interior of the longitudinal rod 15, and the fixed sleeve column 45 passes through the accommodating groove 14 to the interior of the adjacent sliding groove 32. One end of the passive card 44 is movably inserted in the interior of the fixed sleeve column 45, and the other end of the passive card 44 is bent. A rotating groove 450 is provided at the top of the fixed sleeve column 45, and a movable groove 440 is provided at the top of the passive card 44. A limiting plate 451 is slidably connected inside the movable groove 440, and the limiting plate 451 is movably located in the rotating groove 450. Return springs are provided between the outer walls on both sides of the limiting plate 451 and the rotating groove 450.

[0038] Furthermore, the fixed sleeve 45 is fixed in the longitudinal rod 15, and one end of the passive card 44 inserted into the fixed sleeve 45 can be rotatably connected to a disc 441, and a contraction spring 46 is arranged between the disc 441 and the inner wall of the fixed sleeve 45 so that the passive card 44 can be reset after being pressed into the fixed sleeve 45. The purpose of this arrangement is that when the cross bar 19 moves downward and hits the passive card 44 first, the contraction spring 46 will not be compressed, so that the entire longitudinal rod 15 and the pressure plate 8 at the bottom thereof move downward at the same time and contact the paperboard 10. When the cross bar 19 continues to move downward, the pressure plate 8 is subjected to the reaction force of the fixed paperboard 10 and will not move. When the passive card 44 is bent, it starts to rotate, and the limit plate 451 compresses the spring on one side until the bent part of the passive card 44 faces downward, and then continues to be squeezed by the downward movement of the cross bar 19, and the passive card 44 is easily pressed into the fixed sleeve column 45, and the contraction spring 46 is squeezed and contracted until the cross bar 19 completely passes through the passive card 44, and the pressing plate 8 is in normal contact with the cardboard 10; when the electric telescopic rod 6 retracts the cutting blade 5 to finish cutting, the cross bar 19 returns to rise and squeezes the passive card 44 in the same way, until the longitudinal rod 15 is restricted by the inner wall of the top of the accommodating groove 14 and stops moving, the flat pressing transmission also drives the entire pressing plate 8 to reset in the same way.

[0039] A support plate 2 11 is fixed to the outer wall of one side of the support plate 2 by screws, and a plurality of legs 1 are fixed to the bottom of the support plate 2 and the support plate 2 11 to support the entire cutting equipment. The tops of the support plates 1 2 and the support plates 2 11 are rotatably connected with a plurality of linearly evenly arranged support rollers 9 for supporting and transferring the cigarette box cardboard 10. The two pressing wheels 27 are both located directly above the film plate 28, and the parts where the two film plates 28 are close to each other are in an oblique angle and coincide with the rotating outer peripheral surface of the pressing wheel 27. Two cutting position support plates 211 are fixed to the tops of the support plates 1 2 and the support plates 2 11, and the two cutting position support plates 211 are symmetrically distributed on both sides of the cutting blade plate 5, and a gap is left between the two cutting position support plates 211 for observing the cutting blade plate 5. The two cutting position support plates 211 are located between two of the support rollers 9 and directly below the corresponding film plates 28.

[0040] Specifically, the support rollers 9 can be driven by several identical rotating motors to rotate at the same speed at the same time, or all the support rollers 9 can be driven by the same transmission belt to rotate simultaneously to drive the input of the packaging cardboard 10. The support rollers 9 further drive the packaging cardboard 10 to the cutting position and stop rotating. At this time, the electric telescopic rod 6 is started to enable the cutting blade 5 to cut the cardboard 10.

[0041] Reference Fig.11As shown, the arrangement of the film plate 28 and the pressure wheel 27 is to achieve that when the pressure wheel 27 presses the bevel of the film plate 28, the film plates 28 on both sides tend to move outward, so that the cardboard 10 can be pulled apart when the cutting blade 5 cuts the cardboard 10, thereby reducing the problem of burrs or warping of the bottom cardboard 10 when cutting.

[0042] The top of the support arm 24 is rotatably connected to the limit shaft 23, and the outer part of the threaded rod 4 is slidably sleeved with an active rotating tooth 33. The same toothed belt 21 is meshed and sleeved between the limit shaft 23 and the active rotating tooth 33. A scale line is engraved on one side of the support arm 24, and an indicator 20 is fixed to the side wall of the toothed belt 21 close to the scale line.

[0043] The threads of the threaded rod 4 are provided on the outer peripheral wall, and a linear groove 400 is also provided on the outer periphery. The active rotating gear 33 slides on the linear groove 400 through the raised portion of the inner peripheral wall. In this way, after the indicator 20 is turned, the active rotating gear 33 can be driven to rotate through the toothed belt 21 to drive the threaded rod 4 to rotate. The rotation of the threaded rod 4 will rise or fall relative to the support arm 24, so that the cutting blade 5 at the bottom moves synchronously. At this time, the passive suspension rod 16 only moves horizontally in the passive groove 25, so that the inclination angle of the entire cutting blade 5 changes.

[0044] It should be clear that the inclination angle of the cutting blade 5 is positively correlated with the rise and fall of the threaded rod 4, and the rise and fall of the threaded rod 4 is proportional to the number of its rotations. Through the engagement of the toothed belt 21, the indicator 20 can indicate the inclination angle of the cutting blade 5 when moving, and the inclination angle of the cutting blade 5 can be accurately indicated by means of a scale.

[0045] The working principle and explanation of the above implementation scheme are further provided: before cutting, for softer and thinner carton boards, the cutting angle is usually 17°-19°; for paper weighing more than 52 grams, the cutting angle is adjusted to 20°-25°; and when cutting hard and thick cardboard 10, the cutting angle is 25°-30°, so that the indicator 20 is adjusted to make the cutting blade 5 reach the specified angle to cut the specified part of the cardboard 10, and then the limit adjustment pressing mechanism corresponding to the hardness of the cardboard 10 is selected, and the electric telescopic rod 6 is started to make the cutting blade 5 cut the cardboard 10 below. When cutting, the pressing plate 8 and the film plate 28 are first driven by the top flat pressing transmission to press the cardboard 10, and the pressing wheel 27 is always in contact with the film plate 28 and falls on the synchronous position of the cutting of the cutting blade 5 and the cardboard 10. The pressing wheel 27 can always press the cardboard 10 in synchronization with the movement of the cutting position of the cutting blade 5 and the cardboard 10 with the pressing effect, and provide a slight pulling effect to ensure the efficiency of cutting and the accuracy of size control.

[0046] The above description enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
