Description

Technical Field

[0001] This utility model relates to the field of cardboard box forming technology, and in particular to a cardboard cutting structure and a cardboard box forming machine. Background Technology

[0002] In the production of cardboard boxes, the cardboard needs to be cut longitudinally, which requires a longitudinal cutting device. Specifically, the longitudinal cutting device uses a cylinder to drive the blade holder to move vertically up and down, causing the blades on the blade holder to move downwards to the cutting position for cutting. Currently, the cutting mechanism on the market is usually set on a crossbeam and moves back and forth along the crossbeam through a transmission structure. Although this achieves the purpose of adjusting the position of the cutting mechanism, its flexibility is far from sufficient. Utility Model Content

[0003] The purpose of this utility model is to design a cardboard cutting structure and a carton forming machine to overcome the shortcomings of the above-mentioned technologies.

[0004] The cardboard cutting structure designed in this utility model includes a support frame with a crossbeam. At least one cutting component is slidably mounted on the crossbeam. The cutting component includes a mounting part one, a mounting part two, and a cutting blade. The mounting part one is slidably connected to the crossbeam along the X-axis, the mounting part two is slidably connected to the mounting part one along the Y-axis, and the cutting blade is slidably connected to the mounting part two along the Z-axis and cuts the cardboard. Each cutting component can slide independently in three axes relative to the crossbeam.

[0005] Further optimization includes a first rack along the X-axis on the crossbeam, a first gear meshing with the first rack on the mounting part, a first drive device for driving the first gear to rotate on the mounting part, a first slide rail in the same direction as the first rack on the crossbeam, and a first slider cooperating with the first slide rail on the mounting part.

[0006] Further optimization includes a second slide rail along the Y axis provided relative to the X axis in the first mounting part, a second slider that cooperates with the second slide rail on the second mounting part, and a second driving device that drives the second slider to reciprocate on the first mounting part.

[0007] In a further optimization, the second mounting part is provided with a third slide rail along the Z-axis relative to the Y-axis. The third slide rail is fitted with a third slider, and the cutting blade is located on the third slider. The second mounting part is provided with a third driving device, and the output end of the third driving device is connected to the third slider.

[0008] Further optimization involves using a vibrating blade as the cutting tool.

[0009] Preferably, the support is also provided with a conveying component and a dispensing component. The cutting component, dispensing component and conveying component are arranged sequentially along the paperboard conveying direction. The dispensing component is used to apply glue to the surface of the paperboard. The conveying component includes an upper roller and a lower roller located on the upper and lower sides of the paperboard. The upper roller can be lifted relative to the lower roller so that the upper roller can switch between two states: moving away from the paperboard and touching the paperboard. When the upper roller moves away from the paperboard, it can avoid the glue dispensing position on the paperboard surface. When the upper roller touches the paperboard, it can convey the paperboard.

[0010] In a further optimization, the upper roller is connected to the support via a transmission assembly. The transmission assembly includes a crank arm rotatably connected to the support. One end of the crank arm is connected to a drive unit, and the other end is connected to the upper roller. The crank arm reciprocates along the support under the drive unit's influence, causing the upper roller to swing up and down. When the upper roller swings upward, it moves away from the cardboard; when the upper roller swings downward, it contacts the cardboard.

[0011] In a further optimization, the upper roller body includes a roller shaft, and rollers are spaced apart along the length direction of the roller shaft. The roller shaft is connected to a curved arm, and the rollers swing up and down with the roller shaft. When the roller shaft swings up, the roller body and the rollers move away from the cardboard together; when the roller shaft swings down, the rollers contact the cardboard.

[0012] In a further optimization, the lower roller body is rotatably connected to the support as the active roller.

[0013] Preferably, the support has a set of conveyor rollers for conveying cardboard located in front of the cutting assembly.

[0014] This utility model also designs a carton forming machine, which includes the above-mentioned cardboard cutting structure.

[0015] The technical effects of this utility model are as follows:

[0016] The cutting assembly includes a mounting part 1 and a mounting part 2 that slide against each other, and a cutting blade. The mounting part 1 is slidably connected to the crossbeam to form X-axis movement, the mounting part 2 is slidably connected to the mounting part 1 to form Y-axis movement, and the cutting blade is slidably connected to the mounting part 2 to form Z-axis movement, thereby enabling the cutting blade to be adjusted in three axes, making the cutting blade position adjustment more precise and flexible.

[0017] The crossbeam is equipped with at least one cutting component, and each cutting component can move independently along the crossbeam in three axes, making the cutting process more flexible and adaptable.

[0018] The support frame is equipped with a dispensing component, a cutting component, and a conveying component in sequence along the cardboard conveying direction. The dispensing component applies glue to the upper surface of the cardboard. After the glue is applied, the cardboard is conveyed by the conveying component, which includes an upper roller and a lower roller. The upper roller can swing up and down relative to the lower roller, so that the upper roller swings upward as the cardboard passes by, thereby avoiding the glue position on the cardboard and ensuring that the subsequent gluing process can proceed normally without affecting the conveying of the cardboard.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model are within the protection scope of the present utility model.

[0028] This utility model includes a support 1. The support 1 is provided with a dispensing component 3, a cutting component 2 and a conveying component 4 in sequence along the conveying direction of the cardboard 5. The cutting component 2 and the dispensing component 3 cut and dispense glue to the cardboard 5 respectively. The surface of the cardboard 5 passes through the conveying component 4 after being dispensed and cut.

[0029] The conveying assembly 4 is located behind the cutting assembly 2. The conveying assembly 4 includes an upper roller 41 and a lower roller 42, which are located on the upper and lower sides of the cardboard 5, respectively, to clamp and convey the cardboard 5.

[0030] In this embodiment, the upper roller 41 can be lifted relative to the lower roller 42 so that the upper roller 41 can switch between two states: moving away from the paperboard 5 and touching the paperboard 5. When the upper roller 41 moves away from the paperboard 5, it can avoid the glue application position on the surface of the paperboard 5. When the upper roller 41 touches the paperboard 5, it can convey the paperboard 5.

[0031] In addition, the lower roller 42 is rotatably connected to the bracket 1 as the active roller. That is, the lower roller 42 is the active roller. When the upper roller 41 swings up, the lower roller 42 can still rotate. The bracket 1 is provided with a fifth driving device 421 at one end of the lower roller 42 to drive the lower roller 42 to rotate, so that the lower roller 42 can rotate independently as the active roller.

[0032] The upper roller 41 is connected to the support 1 via a transmission assembly. The transmission assembly includes a crank arm 6 rotatably connected to the support 1. In this embodiment, the support 1 has crank arms 6 at both ends of the upper roller 41. The crank arms 6 have a V-shaped connecting arm structure. One end of each crank arm 6 is connected to a drive member 7, which is usually an electric telescopic rod, a hydraulic telescopic rod, or an actuating telescopic rod. The other end is connected to the upper roller 41. The middle position of the crank arm 6 is hinged to the support 1. The crank arm 6 reciprocates along the support 1 under the drive of the drive member 7. The crank arm 6 thereby drives the upper roller 41 to swing up and down. When the upper roller 41 swings up, the upper roller 41 moves away from the cardboard 5. The cardboard 5 passes under the upper roller 41 without touching it. When the upper roller 41 swings down, the upper roller 41 touches the cardboard 5. The upper roller 41 and the lower roller 42 clamp the cardboard 5 again and continue to convey the cardboard 5.

[0033] The support 1 is provided with a crossbeam 21, and at least one cutting component 2 is provided on the crossbeam 21. The crossbeam 21 is located above the cardboard 5 and is horizontally arranged. The length direction of the crossbeam 21 is perpendicular to the conveying direction of the cardboard 5. Each cutting component 2 is slidably connected to the crossbeam 21, that is, it slides back and forth along the length direction of the crossbeam 21. Each cutting component 2 slides along the length direction of the crossbeam 21, that is, along the X-axis. Each cutting component 2 includes a mounting part 1 22 slidably connected to the crossbeam 21. The mounting part 1 22 is provided with a mounting part 23. The mounting part 23 is provided with a cutting blade. The cutting blade cuts the cardboard 5.

[0034] In this embodiment, the crossbeam 21 is provided with a first rack 24 along its length, and the first rack 24 is defined as being horizontally positioned along the X-axis.

[0035] Mounting part 22 is provided with a first gear 25 that meshes with the first rack 24. Mounting part 22 is also provided with a first drive device 26 that drives the first gear 25 to rotate. The first gear 25 and the first rack 24 cooperate to realize the reciprocating sliding of mounting part 22 along the X-axis. At the same time, the crossbeam 21 is also provided with a first slide rail 214 in the same direction as the first rack 24. Mounting part 22 is provided with a first slider 215 that cooperates with the first slide rail 214. Through the sliding cooperation between the first slide rail 214 and the first slider 215, mounting part 22 can stably reciprocate along the first rack 24.

[0036] Furthermore, the mounting section 22 is also provided with a second slide rail 27. The extension direction of the second slide rail 27 is the same as the conveying direction of the cardboard 5, that is, the second slide rail 27 is arranged along the horizontal and vertical direction relative to the first rack 24, that is, the second slide rail 27 is arranged along the Y-axis. The mounting section 23 is provided with a second slider 28 that cooperates with the second slide rail 27. The mounting section 22 is also provided with a second driving device 29 that drives the second slider 28 to reciprocate, so as to realize that the mounting section 23 can stably reciprocate along the Y-axis.

[0037] Furthermore, the mounting section 23 is also provided with a third slide rail 210. The extension direction of the third slide rail 210 is perpendicular to the conveying direction of the cardboard 5, that is, the third slide rail 210 is arranged along the vertical direction relative to the mounting section 23, that is, the third slide rail 210 is arranged along the Z-axis. The third slide rail 210 is fitted with a third slider 211, and the cutting blade is located on the third slider 211. The mounting section 23 is provided with a third driving device 216. The output end of the third driving device 216 is connected to the third slider 211 to drive the third slider 211 to reciprocate along the third slide rail 210. In this embodiment, the third driving device 216 includes a driving device and a lead screw. The third slider 211 is slidably connected to the lead screw, and the lead screw is connected to the output end of the driving device, so that the third slider 211 is driven to move along the third slide rail 210 under the drive of the driving device, thereby realizing the reciprocating movement of the cutting blade along the Z-axis.

[0038] The extension directions of the first slide rail 214, the second slide rail 27 and the third slide rail 210 are respectively set as the X, Y and Z directions, so that the cutting blade can move in three axes relative to the cardboard 5, and the cutting blade position can be precisely adjusted.

[0039] In this embodiment, the cutting blade is a vibrating blade, which includes a drive base 212 and a blade head 213. The drive base 212 is mounted on the third slider 211, and the blade head 213 is rotatably connected to the third slider 211. Both the drive base 212 and the blade head 213 move up and down with the third slider 211, thereby realizing the adjustment of the up and down position of the blade head 213. This makes it easy to adjust the height distance between the blade head 213 and the cardboard 5 to adapt to cardboard 5 of different thicknesses. The output end of the drive base 212 is connected to the blade head 213 to drive the blade head 213 to vibrate and cut at a high frequency.

[0040] In addition, the third slider 211 is also provided with a sixth driving device 217, which is used to drive the cutter head 213 to rotate.

[0041] Furthermore, the upper roller body 41 can be a roller structure of various shapes. In this embodiment, the upper roller body 41 includes a roller shaft 411, and rollers 412 are evenly distributed along the length direction of the roller shaft 411, that is, there is a certain distance between adjacent rollers 412. The rollers 412 are usually rubber rollers. The roller shaft 411 is connected to the curved arm 6. The rollers 412 swing up and down with the roller shaft 411. When the roller shaft 411 swings up, the roller body and the rollers 412 move away from the cardboard 5 together. When the roller shaft 411 swings down, the rollers 412 touch the cardboard 5, that is, the cardboard is conveyed through the rollers 412. This can ensure the normal conveying of the cardboard 5, and in actual production, after the cardboard 5 is glued, during the process of the cardboard 5 continuing to be conveyed, the glued position of the cardboard 5 passes through the gap between adjacent rollers 412. In addition, the upward swing of the rollers 412 can minimize the interference of the upper roller body 41 with the glued position.

[0042] Furthermore, the support 1 is provided with a conveyor roller group 8 in front of the dispensing assembly 3. The conveyor roller group 8 is used to convey the cardboard 5 in sequence through the dispensing assembly 3 and the cutting assembly 2, and finally to the conveying assembly 4. At the same time, when the lower roller 42 is swinging upward, the cardboard 5 can also be conveyed stably.

[0043] Furthermore, in this embodiment, the dispensing component 3 is located in front of the cutting component 2, that is, the cardboard 5 is first dispensed with glue and then cut by the cutting component 2. Therefore, after the upper roller 41 is swung up, it can avoid interfering with the dispensing position of the cardboard 5.

[0044] The dispensing assembly 3 is also slidably connected to the crossbeam 21 via a transmission assembly. The dispensing assembly 3 includes a mounting part 31, and the transmission assembly includes a second rack 32 arranged along the length of the crossbeam 21. The mounting part 31 is provided with a second gear 33 that engages with the second rack 32. The mounting part 31 is provided with a fourth drive device 34 that drives the second gear 33 to rotate, so that the mounting part 31 can move laterally back and forth along the crossbeam 21. The crossbeam 21 is provided with a fourth slide rail 35 in the same direction as the second rack 32. The mounting part 31 is also provided with a fourth slider 36 that engages with the fourth slide rail 35. The mounting part 31 is provided with a glue head 37 for dispensing glue onto the surface of the cardboard 5. The glue head 37 has a conventional structure and will not be described in detail here.

[0045] The first drive device 26, the second drive device 29, the third drive device 216, the drive base 212, the fourth drive device 34, the fifth drive device 421, and the sixth drive device 217 can be motors, hydraulic cylinders, or pneumatic cylinders, etc.

[0046] In addition to rack and pinion, slide rail and slider, the aforementioned transmission components 4 and transmission components can also be conventional transmission structures such as belt transmission, lead screw transmission, and chain transmission.

[0047] This utility model also includes a carton forming machine, which includes the above-mentioned cardboard cutting structure.

[0048] This utility model is not limited to the above-described preferred embodiments. Anyone can derive other forms of products under the guidance of this utility model. However, regardless of any changes made in their shape or structure, any technical solution that is the same as or similar to this application falls within the protection scope of this utility model.
