Description

Technical Field

[0001] This utility model relates to the field of corrugated cardboard production technology, specifically to a modular vertical conveyor for corrugated cardboard production. Background Technology

[0002] Existing vertical conveying equipment for corrugated cardboard has limitations: it is mostly fixed installation, making it difficult to move and align quickly; the conveying components and lifting mechanism are integrated and cannot be disassembled, making it suitable only for a single scenario, resulting in low utilization and difficulty in meeting the needs of conveying multiple materials.

[0003] Therefore, this utility model provides a modular vertical conveyor for corrugated cardboard production. The base has casters for movement and positioning, and the conveyor belt and top seat have a detachable structure with bolts and limit wedges. With standardized interfaces, it supports the replacement of support frames and other expansion devices, which helps to improve the flexibility and adaptability of the equipment and meets the urgent needs of the corrugated cardboard production industry for modular and rapid alignment functions of vertical conveyors. Utility Model Content

[0004] To address the shortcomings of existing technologies, the technical solution adopted by this utility model is as follows: a modular vertical conveyor for corrugated cardboard production, comprising: a base, with casters fixedly connected to the bottom outer wall of the base, and a vertical lifting device provided on the top outer wall of the base; the vertical lifting device includes cross lifting rods, which are symmetrically distributed in a linear array along the outer wall of the base; a fixing rod is rotatably connected to the inner wall of one end of each cross lifting rod, and a displacement rod is rotatably connected to the outer wall of the end of each cross lifting rod away from the fixing rod; sliding wheels are symmetrically rotatably connected to the outer wall of the displacement rod; a top seat is slidably connected to the top outer wall of the cross lifting rod via the displacement rod and the sliding wheels; and limit wedges are symmetrically fixedly connected to the top outer wall of the top seat, with the outer wall of the limit wedges slidably connected via limit grooves. The conveyor belt has symmetrically spaced limiting grooves on its bottom outer wall. Side lugs are symmetrically fixed to both the top seat and the outer wall of the conveyor belt. These side lugs are arranged in a linear array along the outer walls of both the top seat and the conveyor belt. Bolts are fixed to the outer walls of the side lugs. During use, initial equipment preparation is performed. The position of the conveyor can be flexibly adjusted using the casters at the bottom of the base. After moving it to the designated docking station on the corrugated cardboard production line, the casters are locked to prevent operational deviation. Next, the conveyor belt is assembled. First, the conveyor belt in the vertical lifting device is aligned and engaged with the limiting wedge at the top of the top seat through the limiting groove at the bottom, initially limiting the lateral displacement of the conveyor belt. Then, bolts are used to fix the conveyor belt to the top seat through the symmetrically distributed side lugs on the outer wall of the top seat, ensuring a rigid connection between the conveyor belt and the top seat and preventing shaking during subsequent conveying.

[0005] Preferably, the outer walls of the base and the top seat are symmetrically fixed with bearing seats, and the inner walls of the bearing seats are rotatably connected with rotating bearings. The top outer wall of the base is fixedly connected with a hydraulic cylinder via a support. According to the required vertical conveying height, the hydraulic cylinder fixed to the support at the top of the base is activated, and the piston rod of the hydraulic cylinder extends or retracts, transmitting linear power to the displacement rod. One end of the cross lifting rod is connected to the bearing seat and the rotating bearing via a fixing rod. The bearing seats are symmetrically fixed to the outer walls of the base and the top seat, and the rotating bearing is embedded in the inner wall of the bearing seat, providing a stable rotation fulcrum for the cross lifting rod. The end away from the fixing rod is rotatably connected to the displacement rod. The sliding wheels on the outer wall of the displacement rod slide in cooperation with the inner walls of the base and the top seat respectively. When the piston rod of the hydraulic cylinder pushes the displacement rod, the sliding wheels slide along the inner wall. The hydraulic cylinder stops moving and the lifting mechanism is fixed in place by the fixed rod. Once the top seat reaches the target height, the hydraulic cylinder stops moving and the lifting mechanism is fixed by the hydraulic locking function to ensure the stability of the top seat height. The corrugated cardboard from the previous process enters the feed end of the conveyor belt by pushing or gravity. The friction of the conveyor belt surface, combined with the material's own force, drives the cardboard forward. Since the conveyor belt and the top seat are rigidly fixed, and the top seat is locked at the target height by the lifting device, the cardboard is simultaneously conveyed horizontally and vertically. If the height of the next process is lower than that of the previous process, the lifting device can lower the top seat to achieve vertical downward conveying of the cardboard. If the next process is higher, the top seat is raised to achieve vertical upward conveying. Finally, after the cardboard reaches the discharge end of the conveyor belt, it smoothly enters the next process, completing a single vertical conveying cycle.

[0006] Preferably, the inner wall of the rotating bearing is fixedly connected to the outer wall of the retaining rod, the inner wall of the retaining rod is rotatably connected to the outer wall of the top seat through the bearing seat and the rotating bearing, the outer wall of the displacement rod is slidably connected to the inner wall of the base, and the outer wall of the displacement rod is slidably connected to the inner wall of the top seat through a sliding wheel. When the equipment is no longer used for vertical conveying of corrugated paper, first use a tool to unscrew the bolts connecting the top seat and the side lugs of the conveyor belt to release their rigid fixation, then gently push the conveyor belt horizontally to disengage the limiting groove at the bottom of the conveyor belt from the limiting wedge at the top of the top seat, and the conveyor belt can be completely removed. After disassembly, an extension device matching the limiting structure of the top seat can be assembled for material carrying. First, align and engage the limiting groove at the bottom of the support frame with the limiting wedge on the top seat to initially limit the lateral displacement of the support frame, ensuring structural compatibility with the original conveyor belt assembly logic. Then, align the side lugs of the support frame with the pre-reserved side lugs on the top seat, insert the original specification bolts and tighten them to achieve a rigid connection between the two, ensuring that the support frame does not shake during the lifting process. After assembly, in the production line, turnover boxes containing raw materials can be placed on the support frame. The height of the support frame can be adjusted by driving the lifting device with a hydraulic cylinder, and it can be used as a storage device. The height locking function of the lifting device can be used to raise the pallet to the idle height for temporary storage to avoid occupying ground space. When needed in subsequent processes, it can be lowered to the operating height.

[0007] Preferably, the outer wall of the piston rod of the hydraulic cylinder is rotatably connected to the outer wall of the displacement rod. During the entire operation, the bearing seat and the rotating bearing can reduce the frictional resistance when the fixed rod rotates, ensuring the deployment of the cross lifting rod. The limiting wedge and the limiting groove double restrict the lateral displacement of the conveyor belt, preventing paper jams caused by conveyor belt deviation during corrugated cardboard conveying. The cross lifting rod adopts a linear array distribution, which not only enhances the load-bearing capacity of the top seat to accommodate the simultaneous conveying of multiple corrugated cardboard sheets, but also ensures that the top seat remains horizontal during the lifting process, preventing the cardboard from tilting and falling. The functions of each component are complementary, and together they form the support for the reliable operation of the equipment.

[0008] The beneficial effects of this utility model are as follows: 1. This utility model adopts a detachable structure of bolts and limit wedges for the conveyor belt and top seat, which is conducive to improving the adaptability of the scene and the utilization rate of the equipment. With the standardized interface, the support frame and other expansion devices can be easily replaced, so that the equipment can break through the limitation of a single corrugated paper conveying scene and flexibly adapt to various operation needs such as light-load material transfer and temporary storage, which helps to avoid equipment idleness and improve the overall utilization rate of the equipment.

[0009] 2. By incorporating casters, this utility model allows for flexible adjustment of the equipment position, enabling rapid docking with various workstations on the production line. Alignment can be completed without fixed installation, reducing the time required for equipment relocation and adjustment. This enhances the equipment's adaptability to different production line layouts and improves the efficiency of production process integration. Attached Figure Description

[0013] Example

[0014] Please see Figure 1 - Figure 5 This utility model provides a technical solution: a modular vertical conveyor for corrugated cardboard production, comprising: a base 1, with casters 2 fixedly connected to the bottom outer wall of the base 1, and a vertical lifting device 6 provided on the top outer wall of the base 1; the vertical lifting device 6 includes cross lifting rods 60, which are symmetrically distributed in a linear array along the outer wall of the base 1, with a retaining rod 61 rotatably connected to the inner wall of one end of each cross lifting rod 60, and a displacement rod 62 rotatably connected to the outer wall of the end of each cross lifting rod 60 away from the retaining rod 61, the outer wall of which is symmetrically rotated. A sliding wheel 63 is dynamically connected to the top outer wall of the cross lifting rod 60, and a top seat 64 is slidably connected to the top outer wall of the top seat 64 via a displacement rod 62 and a sliding wheel 63. A limiting wedge 65 is symmetrically fixedly connected to the top outer wall of the top seat 64, and a conveyor belt 69 is slidably connected to the outer wall of the limiting wedge 65 via a limiting groove 66. The limiting groove 66 is symmetrically opened on the bottom outer wall of the conveyor belt 69. Side ears 67 are symmetrically fixedly connected to the outer walls of the top seat 64 and the conveyor belt 69, and the side ears 67 are linearly arrayed along the outer walls of the top seat 64 and the conveyor belt 69, respectively. Bolts 68 are fixedly connected to the outer walls of the side ears 67.

[0015] The outer walls of the base 1 and the top seat 64 are symmetrically fixed with bearing seats 3, the inner walls of the bearing seats 3 are rotatably connected with rotating bearings 4, and the top outer wall of the base 1 is fixedly connected with a hydraulic cylinder 5 through a support.

[0016] The inner wall of the rotating bearing 4 is fixedly connected to the outer wall of the retaining rod 61. The inner wall of the retaining rod 61 is rotatably connected to the outer wall of the top seat 64 through the bearing seat 3 and the rotating bearing 4. The outer wall of the displacement rod 62 is slidably connected to the inner wall of the base 1. The outer wall of the displacement rod 62 is slidably connected to the inner wall of the top seat 64 through the sliding wheel 63. The outer wall of the piston rod of the hydraulic cylinder 5 is rotatably connected to the outer wall of the displacement rod 62.

[0017] Working principle: When using the equipment, the initial preparation is as follows: the position of the conveyor can be flexibly adjusted with the help of the casters 2 at the bottom of the base 1. After moving it to the designated docking station on the corrugated cardboard production line, lock the casters 2 to prevent deviation during operation. Then, the conveyor belt 69 is assembled. First, the conveyor belt 69 in the vertical lifting device 6 is aligned and engaged with the limiting wedge 65 at the top of the top seat 64 through the limiting groove 66 at the bottom, which initially restricts the lateral displacement of the conveyor belt 69. Then, the top seat 64 and the side ears 67 symmetrically distributed on the outer wall of the conveyor belt 69 are fixed with bolts 68 to ensure that the conveyor belt 69 and the top seat 64 are rigidly connected to avoid shaking during subsequent conveying. Based on the required vertical conveying height, the hydraulic cylinder 5, fixed to the top of the base 1 via a support, extends or retracts, transmitting linear power to the displacement rod 62. One end of the cross lifting rod 60 is connected to the bearing seat 3 and the rotating bearing 4 via a fixing rod 61. The bearing seat 3 is symmetrically fixed to the outer walls of the base 1 and the top seat 64, and the rotating bearing 4 is embedded in the inner wall of the bearing seat 3, providing a stable rotation fulcrum for the cross lifting rod 60. The end away from the fixing rod 61 is rotatably connected to the displacement rod 62. The sliding wheel 63 on the outer wall of the displacement rod 62 slides in cooperation with the inner walls of the base 1 and the top seat 64, respectively. When the piston rod of the hydraulic cylinder 5 pushes the displacement rod 62, the sliding wheel 63 slides along the inner wall, causing the cross lifting rod 60 to unfold or fold around the fixing rod 61 as a fulcrum. When the target height is reached, hydraulic cylinder 5 stops operating and the lifting mechanism is fixed by hydraulic locking to ensure the height of top seat 64 is stable. The corrugated cardboard from the previous process enters the feed end of conveyor belt 69 by pushing or gravity. The friction of the surface of conveyor belt 69, combined with the force of the material itself, drives the cardboard forward. Since conveyor belt 69 and top seat 64 are rigidly fixed, and top seat 64 is locked at the target height by lifting device, the cardboard is simultaneously conveyed horizontally and vertically with conveyor belt 69. If the height of the next process is lower than that of the previous process, the lifting device can lower top seat 64 to achieve downward vertical conveying of cardboard. If the next process is higher, top seat 64 is raised to achieve upward vertical conveying. Finally, after the cardboard reaches the discharge end of conveyor belt 69, it smoothly enters the next process, completing a single vertical conveying cycle.

[0018] When the equipment is no longer used for vertical conveying of corrugated paper, first use a tool to unscrew the bolts 68 connecting the top seat 64 and the side lugs 67 of the conveyor belt 69 to release their rigid fixation. Then, gently push the conveyor belt 69 horizontally to disengage the limiting groove 66 at the bottom of the conveyor belt 69 from the limiting wedge 65 at the top of the top seat 64. The conveyor belt 69 can then be completely removed. After disassembly, an extension device matching the limiting structure of the top seat 64 can be assembled. Using a material carrier frame, first align and engage the limiting groove 66 at the bottom of the carrier frame with the limiting wedge 65 of the top seat 64 to initially limit the lateral displacement of the carrier frame, thus reconnecting it with the original conveyor belt. The assembly logic of conveyor belt 69 is consistent, ensuring structural compatibility. Then, by aligning the side lug 67 on the side of the support frame with the side lug 67 reserved on the top seat 64, the original specification bolts 68 are inserted and tightened to achieve a rigid connection between the two, ensuring that the support frame does not shake during the lifting process. After assembly, in the production line, turnover boxes containing raw materials can be placed on the support frame. The height of the support frame can be adjusted by driving the lifting device through hydraulic cylinder 5, and it can be used as a storage device. The height locking function of the lifting device can be used to raise the pallet to the idle height for temporary storage, avoiding occupying ground space. When needed in subsequent processes, it can be lowered to the operating height.

[0019] Throughout the operation, the bearing housing and rotating bearing reduce the frictional resistance when the retaining rod rotates, ensuring the cross lifting rod unfolds. The limiting wedge and limiting groove double-limit the lateral displacement of the conveyor belt 69, preventing paper jams caused by the offset of the conveyor belt 69 during corrugated cardboard conveying. The cross lifting rod adopts a linear array distribution, which not only enhances the load-bearing capacity of the top seat to accommodate the simultaneous conveying of multiple corrugated cardboard sheets, but also ensures that the top seat remains horizontal during lifting, preventing the cardboard from tilting and falling. The functions of each component are complementary, together forming the support for the reliable operation of the equipment.

[0020] Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art and related fields based on the embodiments of this utility model without creative effort should fall within the protection scope of this utility model. Structures, devices, and operating methods not specifically described and explained in this utility model, unless otherwise specified or limited, shall be implemented according to conventional means in the art.
