Description

Technical Field

[0001] The utility model relates to the technical field of cigarette box production equipment, in particular to a cigarette box cardboard cutting mechanism. Background Art

[0002] During the production and processing of cigarette box cardboard packaging, the printed cigarette box cardboard raw materials need to be cut, which requires the use of a cigarette box cardboard cutting mechanism.

[0003] Chinese patent CN220995574U discloses a cigarette box cardboard cutting mechanism. The cigarette box cardboard cutting mechanism uses a motor and a threaded rod in combination. The operator can adjust the position of the cutting knife and the rotation speed of the cutter according to product requirements. As a result, the device can cut cigarette box cardboards of different specifications, thereby increasing the use effect of the device and reducing the limitations of the device when used. At the same time, the cigarette box cardboard is cut by the cutting knife, the cutter, and the blade, avoiding the situation where the cigarette box cardboard is creased at the place where the cutter is pressed down and contacts the groove by the cylinder to cut the cardboard. However, while solving the problem, the cigarette box cardboard cutting mechanism has the following defects:

[0004] First, the cigarette box cardboard passes between the movable plate and the cutting knife, and the rotating cutting knife cuts the width of the cigarette box cardboard. Therefore, the cutting knife and the top surface of the movable plate should be tangent to each other. During the cutting process, the cutting knife will wear out, resulting in a gap between the cutting knife and the movable plate, which makes it impossible to completely cut the cigarette box cardboard.

[0005] Secondly, after the cutting knife cuts the cigarette box cardboard, the cigarette box cardboard between the two cutting knives loses its support, so the rotating cutting knife rubs against the side of the cigarette box cardboard, which will cause the cigarette box cardboard to bend upward, resulting in the cigarette box cardboard being unable to be smoothly transferred to the position of the cutting knife and blade for cutting. Utility Model Content

[0006] The purpose of the present invention is to at least solve one of the technical defects described in the background technology.

[0007] To this end, one purpose of the present invention is to propose a cigarette box cardboard cutting mechanism, which aims to solve the problem in the prior art that the cigarette box cardboard cutting mechanism cannot cut the cigarette box cardboard completely as the cutting knife wears, and the cigarette box cardboard may not be smoothly transferred to the position of the cutter and blade for cutting.

[0008] To achieve the above object, an embodiment of one aspect of the present utility model provides a cigarette box cardboard cutting mechanism, including a base. A cutting frame is fixedly connected to the top of the base. Two transmission shafts are rotatably connected inside the cutting frame, and the two transmission shafts are arranged vertically. On the outer surface of one end of the two transmission shafts, first gears are fixedly connected, and the first gears on the two transmission shafts mesh with each other. A first motor is fixedly installed on the inner wall of the cutting frame, and the output end of the first motor is fixedly connected to a first driving gear, and the first driving gear meshes with the first gear. Two pressing wheels are clamped on the outer surface of the transmission shaft located above, and two circular cutting knives are clamped on the outer surface of the transmission shaft located below. The inner side of the circular cutting knife is in contact with the outer side of the pressing wheel, and the pressing wheel and the circular cutting knife intersect. A circular ring is fixedly connected to the inner side of the circular cutting knife, a rubber wheel is fixedly connected to the outer surface of the circular ring, a bearing is fixedly connected to one side of the circular ring away from the circular cutting knife, and the outer surface of the bearing is fixedly connected to a U-shaped bracket, and the bottom of the U-shaped bracket is in contact with the top of the base.

[0009] The beneficial effects are as follows:

[0010] First, when the cigarette box cardboard passes between the pressing wheel and the circular cutting knife, the rotating pressing wheel and circular cutting knife can cut the width of the cigarette box cardboard, and the pressing wheel and the circular cutting knife are in an intersecting relationship without gaps, so that the cigarette box cardboard can be cut thoroughly.

[0011] Second, by setting the U-shaped bracket, the U-shaped bracket is rotatably connected to one side of the circular ring through a bearing, so that during the rotation of the circular cutting knife, the U-shaped bracket will not rotate along with it. Therefore, for the cut cigarette box cardboard, the U-shaped bracket can support the bottom of the cigarette box cardboard, so that the side of the cigarette box cardboard will not bend down after rubbing against the circular cutting knife, thus ensuring that the cigarette box cardboard can smoothly enter the next process for cutting.

[0012] Preferably, from any of the above solutions, a hole groove is provided on the outer surface of the transmission shaft, a first spring is fixedly connected inside the transmission shaft, one end of the first spring is fixedly connected to a support plate, a convex plate is fixedly connected to one side of the support plate away from the first spring, a plurality of card slots are provided on the top of the convex plate, and hooks are fixedly connected to both ends of the support plate.

[0013] The beneficial effects are as follows: After pressing the support plate, the convex plate retracts into the transmission shaft. At this time, the distance between the two pressing wheels or the two circular cutting knives can be adjusted. After the adjustment is completed, release the support plate, and the convex plate extends out of the transmission shaft, so that the card slots on the convex plate are stuck on both sides of the pressing wheel or the circular cutting knife, and the pressing wheel or the circular cutting knife can be positioned, so that the cutting width of the cigarette box cardboard can be adjusted. The setting of the hooks does not require continuous pressing of the support plate when adjusting the positions of the pressing wheel and the circular cutting knife, which can save manpower.

[0014] Preferably, any of the above schemes is that the cutting frame is internally rotatably connected to the first transmission roller and the second transmission roller, and the first transmission roller is located below the second transmission roller, a third motor is fixedly installed on the outside of the cutting frame, and the output end of the third motor is fixedly connected to one end of the first transmission roller, a slide groove is provided on both sides of the cutting frame, a slider is slidably connected to the inside of the slide groove, the end of the second transmission roller is rotatably connected to the slider, and a second spring is fixedly connected to the top of the slider, and the top of the second spring is in contact with the top wall of the slide groove.

[0015] The beneficial effect is that for cigarette box cardboards of different thicknesses, when the cigarette box cardboard is placed on one side of the first transmission roller, the rotating first transmission roller will drive the cigarette box cardboard into between the first transmission roller and the second transmission roller, and the second transmission roller will rise appropriately according to the thickness of the cigarette box cardboard and compress the second spring, thereby being suitable for cutting cigarette box cardboards of different thicknesses, and there is no need to manually adjust the distance between the two transmission rollers, and the operation is simple.

[0026] The present invention provides a cigarette box cardboard cutting mechanism.

[0027] Embodiment 1:

[0028] As Figure 1-4 shown, it includes a base 1. A cutting frame 11 is fixedly connected to the top of the base 1. Two transmission shafts 3 are rotatably connected inside the cutting frame 11, and the two transmission shafts 3 are arranged up and down. The outer surfaces of one ends of the two transmission shafts 3 are fixedly connected with first gears 31, and the first gears 31 on the two transmission shafts 3 are meshed with each other. A first motor 5 is fixedly installed on the inner wall of the cutting frame 11. The output end of the first motor 5 penetrates to the outside of the cutting frame 11, and the output end of the first motor 5 is fixedly connected with a first driving gear 51. The first driving gear 51 is meshed with the first gear 31. By driving the first driving gear 51 to rotate, the first motor 5 can drive the two first gears 31 to rotate, so as to drive the transmission shafts 3 to rotate. Two pressing wheels 4 are clamped on the outer surface of the upper transmission shaft 3, and two circular cutting knives 41 are clamped on the outer surface of the lower transmission shaft 3. The inner side of the circular cutting knife 41 is in contact with the outer side of the pressing wheel 4, and the pressing wheel 4 intersects with the circular cutting knife 41. As Figure 4 As shown, during the rotation of the pressure wheel 4 and the circular cutter 41, the cigarette box cardboard enters between the pressure wheel 4 and the circular cutter 41. The pressure wheel 4 provides a downward pressure on the cigarette box cardboard, and the circular cutter cuts the cigarette box cardboard upward. Its cutting principle is similar to that of scissors, so that the width of the cigarette box cardboard can be cut. A circular ring 42 is fixedly connected to the inner side of the circular cutter 41, and a rubber wheel 43 is fixedly connected to the outer surface of the circular ring 42. The rubber wheel 43 is located below the pressure wheel 4. The cut cigarette box cardboard passes between the pressure wheel 4 and the rubber wheel 43. Thus, the rotating pressure wheel 4 and the rubber wheel 43 can convey the cut cigarette box cardboard. And the rubber wheel 43 has elasticity. Therefore, for thicker cigarette box cardboard, the rubber wheel 43 can be slightly compressed according to the thickness of the cigarette box cardboard. So it can be applied to cigarette box cardboard of different thicknesses. A bearing 44 is fixedly connected to one side of the circular ring 42 away from the circular cutter 41, and a U-shaped bracket 45 is fixedly connected to the outer surface of the bearing 44. When the circular cutter 41 rotates, due to the effect of the bearing 44, the U-shaped bracket 45 will not rotate along with it, and the bottom of the U-shaped bracket 45 fits with the top of the base 1. The side of the cut cigarette box cardboard fits with the inner side of the circular cutter 41. Therefore, when the circular cutter 41 rotates, it带动 the cigarette box cardboard downward. At this time, the U-shaped bracket 45 can support the cigarette box cardboard to avoid the problem that the cigarette box cardboard is带动 downward and bent by the circular cutter 41.

[0029] Specifically, as Figure 2 shown, two roller shafts 6 are rotatably connected inside the cutting frame 11, and the two roller shafts 6 are arranged vertically. Cutting knives 61 are fixedly connected to the outer surfaces of the two roller shafts 6. After the two roller shafts 6 rotate one week, the cutting knives 61 on the two roller shafts 6 can fit together, so as to realize the cutting of the cigarette box cardboard. Second gears 62 are fixedly connected to the outer surfaces of one ends of the two roller shafts 6, and the two second gears 62 mesh with each other. A second motor 63 is fixedly installed inside the cutting frame 11, and the output end of the second motor 63 penetrates to the outside of the cutting frame 11. A second driving gear 64 is fixedly connected to the output end of the second motor 63, and the second driving gear 64 meshes with the second gear 62. The second motor 63 drives the second gear 62 to rotate through the second driving gear 64, so as to achieve the purpose of driving the roller shaft 6 to rotate.

[0030] Specifically, as <0,000,073>shown, a first transmission roller 12 and a second transmission roller 14 are rotatably connected inside the cutting frame 11, and the first transmission roller 12 is located below the second transmission roller 14. A third motor 13 is fixedly installed outside the cutting frame 11, and the output end of the third motor 13 is fixedly connected to one end of the first transmission roller 12. The third motor 13 drives the first transmission roller 12 to rotate, so that the cigarette box cardboard can pass between the first transmission roller 12 and the second transmission roller 14.

[0031] ​It should be noted that the outer side of the circular cutter 41 refers to the side close to the inner wall of the cutting frame 11, and the side opposite to the two circular cutters 41 is the inner side. The outer side of the pressure wheel 4 refers to the side close to the inner wall of the cutting frame 11, and the side opposite to the two pressure wheels 4 is the inner side.

[0032] Example 2:

[0033] like Figure 3-4 As shown, on the basis of Example 1, the transmission shaft 3 is hollow, and a hole groove 32 is provided on the outer surface of the transmission shaft 3. A first spring 33 is fixedly connected to the inside of the transmission shaft 3, and one end of the first spring 33 is fixedly connected to a support plate 34. The first spring 33 can support the support plate 34, and a convex plate 35 is fixedly connected to the side of the support plate 34 away from the first spring 33. The convex plate 35 can protrude from the outer surface of the transmission shaft 3 through the hole groove 32, and a plurality of slots 36 are provided on the top of the convex plate 35. The pressure wheel 4 or the circular cutter 41 is slidably sleeved on the outer surface of the transmission shaft 3, and the pressure wheel 4 or the circular cutter 41 is positioned by being stuck in the slot 36 so that it cannot slide, and the convex plate 35 is contracted by pressing the support plate 34 from both ends. When the cam 35 is in the closed position, the first spring 33 is extended, so that the cam 35 is extended from the transmission shaft 3, so that the first spring 33 is extended and the cam 35 is extended from the transmission shaft 3, so that the first spring 33 is extended and the cam 35 is extended from the transmission shaft 3, so that the first spring 33 is extended and the cam 35 is extended from the transmission shaft 3, so that the first spring 33 is extended and the cam 35 is extended from the transmission shaft 3, so that the first spring 33 is extended and the cam 35 is extended from the transmission shaft 3, so that the first spring 33 is extended and the cam 35 is extended from the transmission shaft 3, so that the first spring 33 is extended and the cam 35 is extended from the transmission shaft 3, so that the first spring 33 is extended and the cam 35 is extended from the transmission shaft 3, so that the first spring 33 is extended and the cam 35 is extended from the transmission shaft 3, so that the first spring 33 is extended and the cam 35 is extended from the transmission shaft 3, so that the first spring 33 is extended and the cam 35 is extended from the transmission shaft 3, so that the first spring 33 is extended and the cam 35 is extended from the transmission shaft 3, so that the first spring 33 is extended and the cam 35 is extended from the transmission shaft

[0034] Example 3:

[0035] like Figure 5 As shown, on the basis of Example 1 or Example 2, a slide groove 15 is opened on both sides of the cutting frame 11, and a slider 16 is slidably connected inside the slide groove 15. The end of the second transmission roller 14 is rotatably connected in the slider 16, and the top of the slider 16 is fixedly connected to the second spring 17. The top of the second spring 17 is in contact with the top wall of the slide groove 15. The second transmission roller 14 is supported by the second spring 17 so that it has a certain upward and downward movable space, so that for cigarette box cardboards of different thicknesses, the second transmission shaft 14 can move upward accordingly to ensure that the cigarette box cardboards can pass through.

[0036] The working principle of the present utility model is as follows: when in use, the cigarette box cardboard is placed between the first transmission shaft 12 and the second transmission shaft 14. The rotating first transmission shaft 12 and the second transmission shaft 14 send the cigarette box cardboard between the pressing wheel 4 and the circular cutter 41 to cut the width of the cigarette box cardboard. The cut cigarette box cardboard slides along the convex bracket 45 to between the two rollers 6.
