Description

Technical Field

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

[0002] The cardboard feeding and conveying system in carton production is a crucial link in ensuring efficient production operations. This automated system accurately grasps stacked cardboard and transports it systematically to subsequent processing stations. Equipped with advanced sensors, it monitors the position and quantity of cardboard in real time, ensuring accurate and continuous feeding. The conveyor speed can be flexibly adjusted according to production needs, effectively improving production efficiency. The robust and durable conveyor belt can carry cardboard of different sizes and weights, and possesses excellent stability, reducing cardboard shaking and damage during transport, providing strong support for high-quality and high-efficiency carton production.

[0003] Existing conveyor equipment provides insufficient protection for the cardboard surface during operation. For example, rough conveyor belts or uneven roller surfaces can cause scratches and wear on the cardboard during transport, affecting its appearance and lowering the product's grade. Poor positioning accuracy is also a problem. In stages requiring precise cardboard positioning, such as printing and slotting, traditional equipment struggles to guarantee accurate placement each time, leading to processing position deviations and increased scrap rates. Therefore, improvements are needed. Utility Model Content

[0013] Compared with the prior art, this utility model provides a cardboard feeding and conveying device for carton production, which has the following beneficial effects:

[0014] 1. This cardboard feeding and conveying device for carton production utilizes a conveying mechanism. A second motor drives a second pulley via its output shaft, which in turn drives a first pulley on a second rotating rod via a belt drive, thus rotating the second rotating rod. The driving teeth at both ends of the second rotating rod are connected to the driven teeth at both ends of the first rotating rod via a conveyor belt, ensuring stable power transmission. The conveyor belt is made of rubber, which, compared to traditional rough conveyor belts, offers better flexibility and smoothness, reducing friction on the cardboard surface during transport and effectively preventing scratches and wear. Furthermore, the rubber conveyor belt provides moderate friction between the conveyor belt and the cardboard, ensuring smooth movement without excessive friction that could damage the cardboard, thus maintaining the cardboard's appearance quality during transport and improving product grade. Simultaneously, the power transmission and conveying structure design ensure stable conveyor belt operation, providing stable feeding support for subsequent cardboard processing steps and contributing to improved quality and efficiency throughout the entire carton production process.

[0015] 2. This cardboard feeding and conveying device for carton production utilizes a correction mechanism that employs precise mechanical transmission and pneumatic control to correct cardboard deviation and improve positioning accuracy. A sliding rod on the fixed block provides stable sliding support for the sliding frame. When correction is needed, the cylinder can extend and retract, moving the sliding frame along the sliding rod. Simultaneously, the first motor drives a gear through its output shaft. Since the gear meshes with a rack on the inner side of the baffle, its rotation causes the sliding frame to move precisely horizontally along the rack direction. During cardboard conveying, if the cardboard position deviates, this correction mechanism can promptly adjust the cardboard position, returning it to the correct conveying track. Compared to traditional equipment, this device's correction mechanism offers significant advantages in printing and slotting stations where precise cardboard positioning is required, preventing processing position deviations caused by inaccurate cardboard positioning and greatly reducing the scrap rate. Precise deviation control ensures that each cardboard is accurately delivered to its corresponding processing position, guaranteeing the smooth progress of subsequent processing steps, improving product qualification rate, enhancing the accuracy and stability of the entire carton production process, and bringing higher economic benefits to enterprises.

Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0025] This utility model provides the following technical solution:

[0026] Example 1

[0027] Please see Figure 1-3 A cardboard feeding and conveying device for carton production includes a mounting frame 2, a conveying mechanism 3 installed in the middle of the mounting frame 2, baffles 1 installed on both the front and rear sides of the mounting frame 2, and a correction mechanism 4 installed on the bottom inner side of the baffles 1.

[0028] The conveying mechanism 3 includes a second rotating rod 32, which is rotatably connected to the middle left side of the mounting frame 2. A first rotating rod 31 is rotatably connected to the middle right side of the mounting frame 2. Both ends of the second rotating rod 32 are fixedly connected to driving teeth 37. Both ends of the first rotating rod 31 are rotatably connected to driven teeth 38. A conveyor belt 35 is connected between the driving teeth 37 and the driven teeth 38. An arc-shaped support block 36 is fixedly connected to the middle bottom of the conveyor belt 35 inside the mounting frame 2. The design of the arc-shaped support block 36 can ensure that the conveyor belt 35 itself is not too loose.

[0029] The second motor 39 drives the second pulley 391 to rotate via its output shaft. This rotation, via belt 34, causes the first pulley 33 on the second rotating rod 32 to rotate, which in turn drives the second rotating rod 32 to rotate. The drive teeth 37 at both ends of the second rotating rod 32 are connected to the driven teeth 38 at both ends of the first rotating rod 31 via the conveyor belt 35. This structure ensures stable power transmission. The conveyor belt 35 is made of rubber. Compared to traditional rough conveyor belts, rubber has better flexibility and smoothness, reducing friction on the cardboard surface during transport and effectively preventing scratches and wear. Furthermore, the friction between the rubber conveyor belt 35 and the cardboard is moderate, ensuring smooth movement without excessive friction that could damage the cardboard, thus ensuring the appearance quality of the cardboard during transport and improving product grade. Simultaneously, the power transmission and conveyor structure design ensure stable operation of the conveyor belt 35, providing stable feeding support for subsequent cardboard processing steps and contributing to improved quality and efficiency of the entire carton production process.

[0030] The second rotating rod 32 is fixedly connected to the first pulley 33 near the front side. The second motor 39 is fixedly connected to the bottom left side of the mounting bracket 2. The second pulley 391 is fixedly connected to the rear end of the second motor 39 corresponding to the first pulley 33. A belt 34 is used for transmission between the second pulley 391 and the first pulley 33.

[0031] The second motor 39 is equipped with an output shaft, and the second motor 39 is fixedly connected to the second pulley 391 through the output shaft.

[0032] Example 2

[0033] Please see Figure 1-5 Furthermore, based on Embodiment 1, the correction mechanism 4 further includes a fixed block 41, which is fixedly connected to the inner side of the bottom of the baffle 1. A sliding rod 42 is fixedly connected to the inner side of the fixed block 41. A sliding frame 45 is slidably connected in the middle of the sliding rod 42. A cylinder 43 is fixedly connected in the middle of the inner side of the sliding frame 45. A first motor 44 is fixedly connected to the rear side of the top of the sliding frame 45. A gear 46 is fixedly connected to the bottom of the first motor 44. A rack 47 meshes with the outer side of the gear 46. The outer side of the rack 47 is fixedly connected to the inner side of the baffle 1.

[0034] The corrective mechanism 4, through precise mechanical transmission and pneumatic control, corrects the alignment of the cardboard, improving positioning accuracy. The sliding rod 42 on the fixed block 41 provides stable sliding support for the sliding frame 45. When correction is needed, the cylinder 43 can extend and retract, moving the sliding frame 45 along the sliding rod 42. Simultaneously, the first motor 44 drives the gear 46 to rotate via its output shaft. Since the gear 46 meshes with the rack 47 inside the baffle 1, its rotation causes the sliding frame 45 to move precisely horizontally along the rack 47. During cardboard conveying, if the cardboard position deviates, the corrective mechanism 4 can promptly adjust the cardboard position, returning it to the correct conveying track. Compared to traditional equipment, the corrective mechanism 4 of this device offers significant advantages in printing, slotting, and other workstations requiring precise cardboard positioning, preventing processing position deviations caused by inaccurate cardboard placement and greatly reducing scrap rates. Precise deviation control ensures that each cardboard is accurately delivered to its corresponding processing position, guaranteeing the smooth progress of subsequent processing steps, improving product qualification rate, enhancing the accuracy and stability of the entire carton production process, and bringing higher economic benefits to enterprises.

[0035] The first motor 44 is equipped with an output shaft, and the first motor 44 is fixedly connected to the gear 46 through the output shaft.

[0036] The mounting bracket 2 is T-shaped, and the length of the correction mechanism 4 is two-thirds of the length of the mounting bracket 2. The correction mechanism 4 is located on the inside of the T-shape of the mounting bracket 2.

[0037] The conveyor belt 35 is made of rubber, and a silicone block is installed on the top of the cylinder 43.

[0038] In actual operation, when this device is in use, the second motor 39 drives the second pulley 391 to rotate via the output shaft through the conveyor mechanism 3. This rotation is then transmitted via the belt 34, causing the first pulley 33 on the second rotating rod 32 to rotate, which in turn drives the second rotating rod 32 to rotate. The drive teeth 37 at both ends of the second rotating rod 32 are connected to the driven teeth 38 at both ends of the first rotating rod 31 via the conveyor belt 35. This structure ensures stable power transmission. The conveyor belt 35 is made of rubber. Compared to traditional rough conveyor belts, rubber has better flexibility and smoothness, reducing friction on the cardboard surface during transport and effectively preventing scratches and wear. Furthermore, the friction between the rubber conveyor belt 35 and the cardboard is moderate, ensuring smooth movement of the cardboard without damaging it due to excessive friction. This ensures the appearance quality of the cardboard during transport and improves the product's grade. Meanwhile, the design of the power transmission and conveying structure ensures the stable operation of the conveyor belt 35, providing stable feeding support for subsequent cardboard processing steps, which helps to improve the quality and efficiency of the entire carton production process.

[0039] Precise mechanical transmission and pneumatic control enable cardboard alignment, improving positioning accuracy. The sliding rod 42 on the fixed block 41 provides stable sliding support for the sliding frame 45. When alignment is needed, the cylinder 43 can extend and retract, moving the sliding frame 45 along the sliding rod 42. Simultaneously, the first motor 44 drives the gear 46 to rotate via its output shaft. Since the gear 46 meshes with the rack 47 inside the baffle 1, its rotation causes the sliding frame 45 to move precisely horizontally along the rack 47. During cardboard conveying, if cardboard position deviates, the alignment mechanism 4 can promptly adjust the cardboard position, returning it to the correct conveying track. Compared to traditional equipment, the alignment mechanism 4 of this device offers significant advantages in printing, slotting, and other workstations requiring precise cardboard positioning, preventing processing position deviations caused by inaccurate cardboard placement and greatly reducing scrap rates. Precise deviation control ensures that each cardboard is accurately delivered to its corresponding processing position, guaranteeing the smooth progress of subsequent processing steps, improving product qualification rate, enhancing the accuracy and stability of the entire carton production process, and bringing higher economic benefits to enterprises.
