Description

Technical Field

[0001] This utility model relates to the field of cardboard box production and cutting, specifically a cutting device for cardboard box production. Background Technology

[0002] Cardboard boxes are a common type of outer packaging used in the packaging industry. The raw material for cardboard boxes is paperboard, which requires a cutting process to obtain paperboard of a predetermined size during its production and processing.

[0003] According to publicly available patent CN209955395U, a cardboard cutting device for carton production includes a base plate. Symmetrically arranged columns are positioned at the top of the base plate, and each column has an electric telescopic rod at its top. A housing is positioned at the top of each electric telescopic rod. A conveyor belt 1 and a conveyor belt 2 are symmetrically arranged at the top of the base plate between the columns. The side of conveyor belt 1 away from conveyor belt 2 passes through the feed inlet of the column, and the side of conveyor belt 2 away from conveyor belt 1 passes through the discharge outlet of the column. A cutting mechanism is located inside the housing. The cutting mechanism includes a drive motor located inside the housing. A collar is provided at the output end of the drive motor. Connecting rod 1 and connecting rod 2 are symmetrically arranged on both sides of the collar. Both connecting rod 1 and connecting rod 2 are inclined. In the process of realizing this utility model, the inventors discovered that in the prior art… At least the following problems remain unresolved: The distance between the housing and the base plate can be adjusted by regulating the electric telescopic rod, thus enabling the cutting of cardboard of different thicknesses. The cutting mechanism can reciprocate to cut cardboard on conveyor belts one and two, greatly increasing cutting efficiency and improving work efficiency. It can flexibly adjust the cutting width and length according to the size requirements of different products, significantly improving work efficiency and meeting the market demand for small-batch, multi-variety packaging cartons. However, in traditional conveyor-driven cardboard transport, the lack of limiting points on both sides of the cardboard makes it prone to deviation during transport, resulting in uneven cut ends and further affecting the quality of the cardboard cutting. Therefore, a new technical solution is needed to address these issues. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology, adapt to the needs of reality, and provide a cutting device for carton production. This device solves the technical problem that when cardboard is conveyed by a conveyor, the cardboard is prone to deflection during conveying because there are no limiting points on both sides, resulting in uneven cutting ends and further affecting the quality of cardboard cutting.

[0005] To achieve the purpose of this utility model, the technical solution adopted by this utility model is as follows: a cutting device for carton production is designed, including two belt conveyors, the two belt conveyors are on the same horizontal line, each of the two belt conveyors is equipped with an anti-deviation mechanism, and a cutting mechanism is set between the two belt conveyors. The anti-deviation mechanism includes baffles sleeved on both sides of the outer side of the conveyor belt of the belt conveyor. The baffles are annular, and the inner wall of the baffles slides against the conveyor belt of the belt conveyor. A connecting hole is opened at the top of the inner cavity of the baffle. Multiple rotating shafts are rotatably connected to the top of the inner cavity of the connecting hole through bearings. Rollers are fixedly connected to the bottom of the multiple rotating shafts. The bottom of the rollers does not contact the surface of the conveyor belt of the belt conveyor, and the diameter of the rollers is greater than the thickness of the baffles. An adjustment mechanism is set between the bottom of the baffles and the belt conveyor.

[0006] The cutting mechanism is used for cutting cardboard.

[0007] Preferably, the adjusting mechanism includes a support plate disposed below the two belt conveyors. The support plate is fixedly connected to the support legs of the two belt conveyors. An adjusting groove is formed in the middle of the surface of the support plate. A bidirectional lead screw is rotatably connected between the two sides of the inner cavity of the adjusting groove through bearings. Two adjusting blocks are slidably connected in the adjusting groove, and the two adjusting blocks are respectively threaded onto the outer sides of the bidirectional lead screw. A connecting rod is fixedly connected to each of the two adjusting blocks. A U-shaped frame is fixedly connected between each of the two connecting rods and the bottom of the two baffles on the same side. A first drive motor is fixedly installed at one end of the outer side of the support plate. The drive end of the first drive motor rotates through the support plate and is fixedly connected to the bidirectional lead screw through a coupling.

[0008] Preferably, the cutting mechanism includes columns fixedly installed on opposite sides of two belt conveyors. A top plate is fixedly connected to the top of the columns, and a horizontal drive mechanism is provided at the bottom of the top plate. A cylinder is provided on the horizontal drive mechanism, and a mounting frame is fixedly connected to the drive end of the cylinder. The mounting frame is inverted U-shaped, and a connecting shaft is rotatably connected between the two sides of the inner cavity of the mounting frame through bearings. A cutting disc is fixedly connected to the outer side of the connecting shaft, and a second drive motor is fixedly installed at one outer end of the mounting frame. The drive end of the second drive motor rotatably passes through the mounting frame and is fixedly connected to the connecting shaft through a coupling.

[0009] Preferably, the horizontal drive mechanism includes a groove formed on the top plate, a first lead screw rotatably connected between the two sides of the inner cavity of the groove via bearings, a slider slidably connected in the groove, the slider being threaded onto the outside of the first lead screw, and the slider being fixedly connected to a cylinder, and a third drive motor being fixedly installed at one end of the outer side of the top plate, the drive end of the third drive motor rotatably passing through the top and being fixedly connected to the first lead screw via a coupling.

[0010] Preferably, mounting plates are fixedly connected to both ends of the mounting frame, and telescopic rods are fixedly connected to both sides of the bottom of the mounting plates. The two telescopic rods are respectively placed on both sides of the cutting disc, and pressure rollers are fixedly connected to the bottom of the telescopic rods. The bottom height of the cutting disc is higher than the bottom height of the pressure rollers. Springs are sleeved on the outer side of the telescopic rods, and the two ends of the springs are fixedly connected to the connecting frames on the mounting plate and the pressure rollers, respectively.

[0011] Preferably, a pad is fixedly connected between the opposite ends of the two belt conveyors. The surface of the pad is on the same horizontal plane as the surface of the conveyor belt of the belt conveyor. A groove is formed in the middle of the surface of the pad, and the groove is on the same vertical horizontal plane as the cutting disc.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model combines a baffle, connecting hole, rotating shaft, roller, and belt conveyor to limit the movement of cardboard during transport by having the roller contact both ends of the cardboard. This prevents the cardboard from shifting during transport, which would result in uneven cut ends and affect the quality of the cut. Furthermore, during anti-deviation transport, the roller, connected to the connecting hole, reduces friction between the cardboard ends and the roller, thus preventing the friction between the roller and the cardboard ends from exceeding the friction between the cardboard and the conveyor belt, which would otherwise affect the transport of the cardboard.

[0014] 2. This utility model combines a telescopic rod, a spring, and a pressure roller. When the cylinder pushes the cutting disc to contact the cardboard, the pressure roller first contacts both sides of the cardboard cutting position. Then, the cylinder continues to push the cutting disc towards the cardboard cutting position, thereby compressing the spring in conjunction with the contraction of the telescopic rod. As a result, the pressure roller squeezes and limits the cardboard cutting position on both sides during cutting, preventing the cardboard from moving and affecting the cutting quality. Furthermore, as the cutting disc moves to cut, the roller rolls on the cardboard surface, following the movement of the cutting disc, thus always limiting the cutting position of the cardboard.

[0019] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0020] Example 1: A cutting device for cardboard box production, see [link / reference] Figures 1 to 3 The system includes two belt conveyors 1, which are on the same horizontal line. Each belt conveyor 1 is equipped with an anti-deviation mechanism, and a cutting mechanism is located between them. The anti-deviation mechanism includes baffles 3 fitted onto both sides of the conveyor belt of the belt conveyor 1. The baffles 3 are annular, and their inner walls slide against the conveyor belt of the belt conveyor 1. A connecting hole 31 is provided at the top of the inner cavity of the baffle 3. Multiple rotating shafts 34 are rotatably connected to the top of the inner cavity of the connecting hole 31 via bearings. Rollers 32 are fixedly connected to the bottom of each of the multiple rotating shafts 34. The bottom of the rollers 32 does not contact the surface of the conveyor belt of the belt conveyor 1, and the diameter of the rollers 32 is greater than the thickness of the baffle 3. An adjustment mechanism is provided between the bottom of the baffle 3 and the belt conveyor 1. The cutting mechanism is used for cutting the cardboard.

[0021] During operation, the motor on the belt conveyor 1 drives the transmission drum to rotate, which in turn drives the conveyor belt to rotate, thus conveying the cardboard to be cut to the cutting mechanism below for cutting. When the cardboard is being conveyed, the roller 32 contacts both ends of the conveyed cardboard to limit its movement and prevent it from shifting during the conveying process, which would cause unevenness at the cut end of the cardboard and affect the quality of the cardboard cutting. Furthermore, when preventing the cardboard from shifting during conveying, since the roller 32 is rotatably connected in the connecting hole 31, the two ends of the cardboard rub against the roller 32 during the conveying process, reducing the frictional force between the roller 32 and the two ends of the conveyed cardboard. This prevents the frictional force between the roller 32 and the two ends of the cardboard from being greater than the frictional force between the cardboard and the conveyor belt on the belt conveyor 1, which would affect the conveying of the cardboard.

[0022] For details, see Figure 3 The adjusting mechanism includes a support plate 2 positioned below the two belt conveyors 1. The support plate 2 is fixedly connected to the support legs of the two belt conveyors 1. An adjusting groove 22 is formed in the center of the surface of the support plate 2. A bidirectional lead screw 24 is rotatably connected between the two sides of the inner cavity of the adjusting groove 22 via bearings. Two adjusting blocks 23 are slidably connected within the adjusting groove 22, and the two adjusting blocks 23 are threaded onto the outer sides of the bidirectional lead screw 24. A connecting rod 35 is fixedly connected to each of the two adjusting blocks 23. A U-shaped frame 33 is fixedly connected to the bottom of the two baffles 3 on the same side. A first drive motor 21 is fixedly installed at one end of the outer side of the support plate 2. The drive end of the first drive motor 21 rotates through the support plate 2 and is fixedly connected to the bidirectional lead screw 24 through a coupling. By starting the first drive motor 21, the bidirectional lead screw 24 is driven to rotate, thereby adjusting the distance between the two baffles 3 on both sides of the same belt conveyor 1. This allows for limiting and preventing deviation of the two ends of the conveyed cardboard of different sizes from contacting the roller 32, further improving the applicability of the device.

[0023] Further, see Figure 2The cutting mechanism includes columns 4 fixedly installed on opposite sides of two belt conveyors 1. A top plate 41 is fixedly connected to the top of each column 4. A horizontal drive mechanism is provided at the bottom of the top plate 41. The horizontal drive mechanism includes a groove 52 formed on the top plate 41. A first lead screw 51 is rotatably connected between the two sides of the inner cavity of the groove 52 via bearings. A slider 53 is slidably connected within the groove 52, and the slider 53 is threaded onto the outside of the first lead screw 51. The slider 53 is fixedly connected to a cylinder 7. A third drive motor 5 is fixedly installed at one end of the outer side of the top plate 41. The drive end of the third drive motor 5 rotates through the top and is fixedly connected to the first lead screw 51 via a coupling. A cylinder 7 is provided on the horizontal drive mechanism. A mounting bracket 71, which is inverted U-shaped, is fixedly connected to the drive end of the cylinder 7. A connecting shaft 74 is rotatably connected between the two sides of the inner cavity of the mounting frame 71 via bearings. A cutting disc 73 is fixedly connected to the outer side of the connecting shaft 74. A second drive motor 72 is fixedly installed at one end of the outer side of the mounting frame 71. The drive end of the second drive motor 72 rotates through the mounting frame 71 and is fixedly connected to the connecting shaft 74 via a coupling. When the cutting position of the cardboard is transported to directly below the cutting disc 73, the starting cylinder 7 pushes the cutting disc 73 to contact the cardboard. Then, the second drive motor 72 drives the cutting disc 73 to rotate at high speed to cut the cardboard. During cutting, the third drive motor 5 is started to drive the first lead screw 51 to rotate, thereby enabling the cutting disc 73 to move back and forth on the cardboard (the back and forth movement of the cutting disc 73 is achieved by the forward and reverse rotation of the motor, and how the motor achieves forward and reverse rotation is a known technology, which will not be elaborated here), thus enabling rapid cutting of the cardboard.

[0024] It is worth noting that, see Figure 2 The mounting bracket 71 has mounting plates 8 fixedly connected to both ends. Telescopic rods 82 are fixedly connected to both sides of the bottom of the mounting plates 8. The two telescopic rods 82 are respectively placed on both sides of the cutting disc 73. Pressure rollers 83 are fixedly connected to the bottom of the telescopic rods 82. The bottom of the cutting disc 73 is higher than the bottom of the pressure rollers 83. Springs 81 are sleeved on the outer side of the telescopic rods 82. The two ends of the springs 81 are fixedly connected to the connecting brackets on the mounting plates 8 and the pressure rollers 83, respectively. When the cylinder 7 pushes the cutting disc 73 against the paper... When the board contacts, the pressure roller 83 first contacts both sides of the cardboard cutting position. Then, the cylinder 7 continues to push the cutting disc 73 to move towards the cardboard cutting position, thereby compressing the spring 81 in conjunction with the contraction of the telescopic rod 82. Thus, when the cardboard is cut, the pressure roller 83 squeezes and limits both sides of the cardboard cutting position to prevent the cardboard from moving and affecting the cutting quality. Furthermore, when the cutting disc 73 moves to cut, the roller rolls on the cardboard surface and follows the movement of the cutting disc 73, thus always limiting the cutting of the cardboard.

[0025] It is worth noting that, see Figure 1 A pad 6 is fixedly connected between the opposite ends of the two belt conveyors 1. The surface of the pad 6 is on the same horizontal plane as the surface of the conveyor belt of the belt conveyor 1. A groove 61 is provided in the middle of the surface of the pad 6. The groove 61 and the cutting disc 73 are on the same vertical horizontal plane. When the cardboard is cut with a limiting position, the pad 6 supports the cardboard to avoid the pressure of the pressure roller 83 on the cardboard being too great, which may cause the cardboard to deform or even break. At the same time, the groove 61 facilitates the placement of the cutting disc 73, thereby avoiding damage to the pad 6 when the cutting disc 73 cuts the cardboard.
