Abstract
Description
Technical Field
[0001] This utility model relates to conveying equipment, and in particular to a conveyor belt with a lifting structure, which is especially suitable for industrial scenarios such as sheet metal production lines where the accuracy and synchronization of conveying height adjustment are high. It can realize the smooth and synchronous lifting of the conveyor belt and avoid material deviation or equipment damage during the conveying process. Background Technology
[0002] In industrial production processes such as sheet metal production lines, conveyors often need to lift and lower based on the height difference between upstream and downstream equipment to achieve continuous and smooth material transfer. Currently, traditional conveyor belt lifting devices in the industry mostly adopt a combination structure of "dual cylinders (cylinder A and cylinder B) + solenoid valve + air pipe". Its working principle is as follows: the extension and retraction of the two cylinders are controlled by the solenoid valve, and the thrust of the cylinders directly drives the conveyor belt support legs to lift and lower, thereby adjusting the height of the conveyor belt.
[0003] However, this traditional structure has significant drawbacks: because the two cylinders are connected to the air source via separate air pipes, the air pressure inside the pipes is easily affected by factors such as fluctuations in the air source, differences in pipe length, and cylinder wear, making it difficult to achieve perfect synchronization in the extension and retraction speeds and amounts of the two cylinders. This lack of synchronization directly causes inconsistent lifting and lowering movements of the support legs on both sides of the conveyor belt, leading to belt skew (i.e., the belt edge deviating from the conveying path). Belt skew not only causes material transport such as sheet metal to deviate, increasing material loss and rework rates, but it can also cause belt wear and equipment failure due to belt friction against the equipment frame, severely reducing the production efficiency and equipment reliability of the entire production line and failing to meet the requirements for conveying stability in industrial production.
[0004] Therefore, in response to the problems of poor synchronization, easy belt skewing, and low production efficiency of the existing dual-cylinder lifting structure, there is an urgent need to design a conveyor belt lifting scheme with a more reasonable structure and more stable lifting. Utility Model Content
[0005] The purpose of this invention is to overcome the defects of existing technologies, such as asynchronous movement, easy belt cutting and low production efficiency, when the conveyor belt is driven by a dual cylinder for lifting and lowering. It provides a conveyor belt structure driven by a single cylinder and achieving synchronous lifting and lowering through a swing arm-linkage transmission, so as to improve the stability of the conveyor belt lifting and lowering, the reliability of the equipment and the efficiency of the production line.
[0006] To achieve the above and other related objectives, the technical solution provided by this utility model is: a conveyor belt with a lifting structure, including a conveyor belt, a swing arm, a connecting rod, and a cylinder. The conveyor belt is horizontally arranged, the swing arm is located on the bottom side of the conveyor belt, and the connecting rod is rotatably arranged between the swing arm and the conveyor belt via a rotating shaft. The connecting rod has a connecting part one and a connecting part two arranged at an angle. The connecting part one is hinged to the support leg of the conveyor belt, and the connecting part two is hinged to the swing arm. The cylinder is used to drive the swing arm to swing and adjust the height of the conveyor belt through the connecting rod.
[0007] A preferred technical solution is that the telescopic end of the cylinder is hinged to the swing arm.
[0008] The preferred technical solution is that the cylinder is controlled by a solenoid valve.
[0009] The preferred technical solution is that the fixed end of the cylinder is hinged to the base via a second rotating shaft.
[0010] Due to the application of the above technical solution, the beneficial effects of this utility model are as follows:
[0011] Solving the problem of lifting synchronization: A single cylinder combined with a swing arm-linkage transmission structure is adopted. The swing arm is driven to swing by the extension and retraction of the single cylinder. The swing arm then drives the multiple sets of support feet of the conveyor belt to rise and fall synchronously through the linkage. In the entire transmission process, the movement of all support feet is driven by the same cylinder. There is no synchronization deviation caused by air pressure difference, which completely avoids the problem of conveyor belt skewing and ensures the stability of material conveying.
[0012] Improving equipment reliability and production efficiency: Single-cylinder drive reduces the number of moving parts, lowering the probability of failures caused by multi-cylinder wear and pipe leaks; simultaneously, the swing arm-linkage transmission structure provides stable force distribution, minimizes component wear, and extends equipment lifespan. Furthermore, the conveyor belt lifts smoothly without deviation, reducing material rework and equipment downtime for maintenance, significantly improving the continuous production efficiency of the production line.
[0013] Simple structure, low cost and easy maintenance: only one cylinder is needed to realize the lifting function, which reduces the cylinder procurement cost and subsequent maintenance cost; and the swing arm and connecting rod are both rigid structures, which are easy to assemble. Daily maintenance only requires checking the lubrication of the hinge point and the cylinder air pressure, making operation convenient. Attached Figure Description

[0020] like Figures 1 to 2 As shown, according to the overall technical concept of this utility model, a conveyor belt with a lifting structure is provided, including a conveyor belt 1, a swing arm 2, a connecting rod 3 and a cylinder 4. The conveyor belt 1 is horizontally arranged, the swing arm 2 is located on the bottom side of the conveyor belt 1, and the connecting rod 3 is rotatably arranged between the swing arm 2 and the conveyor belt 1 via a rotating shaft 5. The connecting rod 3 has a connecting part 31 and a connecting part 32 arranged at an angle. The connecting part 31 is hinged to the support leg 6 of the conveyor belt 1, and the connecting part 32 is hinged to the swing arm 2. The cylinder 4 is used to drive the swing arm 2 to swing and adjust the height of the conveyor belt 1 through the connecting rod 3.
[0021] like Figures 1 to 2 As shown, in an exemplary embodiment of this utility model, the telescopic end of the cylinder 4 is hinged to the rocker arm 2.
[0022] like Figures 1 to 2 As shown, in one exemplary embodiment of this utility model, the cylinder 4 is controlled by a solenoid valve 7.
[0023] like Figures 1 to 2 As shown, in an exemplary embodiment of this utility model, the fixed end of the cylinder 4 is hinged to the base via a rotating shaft 8.
[0024] Work process
[0025] Lifting action: When the sheet metal production line needs to lift the conveyor belt, the solenoid valve is energized, and the industrial air source enters the rodless chamber of the cylinder through the solenoid valve, pushing the cylinder piston rod to extend; the piston rod drives the swing arm to swing upward around the fixed end of the cylinder (rotating shaft two), and the swing arm pushes the connecting rod upward through rotating shaft one, and the connecting rod connection one drives the support foot to lift upward, thereby realizing the lifting of the conveyor belt height;
[0026] Lowering action: When it is necessary to lower the conveyor belt, the solenoid valve is de-energized (or energized in reverse), the air source enters the rod chamber of the cylinder, and pushes the piston rod to retract; the piston rod pulls the swing arm to swing downward, the connecting rod moves downward under the action of the swing arm, the support foot descends with the connecting rod, and the height of the conveyor belt is reduced;
[0027] Positioning and holding: When the conveyor belt rises to or falls to the target height (e.g., from 300mm to 500mm), the solenoid valve is de-energized, and the cylinder maintains the current extension and retraction state by maintaining pressure through the air source, ensuring that the conveyor belt is highly stable during the conveying process.
[0028] Therefore, this utility model has the following advantages:
[0029] This utility model discloses a conveyor belt with a lifting structure, including a horizontally arranged conveyor belt, a swing arm parallel to the conveyor belt, a connecting rod, a cylinder, and a base. The connecting rod is rotatably connected between the swing arm and the conveyor belt via a rotating shaft. It is integrally formed with a first connecting part and a second connecting part at an angle. The first connecting part is hinged to the conveyor belt support feet, and the second connecting part is hinged to the swing arm. The telescopic end of the cylinder is hinged to the swing arm, and the fixed end is hinged to the base via the second rotating shaft, and its movement is controlled by a solenoid valve. By driving the swing arm to swing with a single cylinder, the connecting rod can synchronously drive multiple sets of support feet to rise and fall, completely avoiding synchronization deviation. At the same time, it reduces moving parts, lowers the probability of failure, improves equipment reliability and production efficiency, and has a simple overall structure, low cost, and easy maintenance. It is suitable for industrial scenarios such as sheet metal production lines where there is a need for adjustable conveying height.
