Description

Technical Field

[0001] This utility model relates to the field of belt conveyor technology, and specifically to a pressing structure. Background Technology

[0002] The conveyor belt chute is an important component for ensuring the stable operation and efficient material transport of the conveyor belt. This device is typically installed in the receiving area of ​​the belt conveyor, and its main function is to restrain material flow, prevent spillage and dust generation during transport, and effectively control material flow rate to avoid blockages and overflows, thereby improving overall conveying efficiency.

[0003] In the chute structure, the baffle plate, as a key sealing component, plays a crucial role in preventing material leakage and reducing dust generated by the impact of falling materials. Because it is usually made of flexible rubber, although it has good sealing performance, its wear resistance and erosion resistance are poor, resulting in rapid wear and frequent replacement, leading to a large maintenance workload. It can be said that replacing the baffle plate is one of the main tasks in the daily maintenance of belt conveyors.

[0004] The clamping structure of the baffle plate directly affects its sealing effect and operational safety. Traditional clamping structures generally suffer from problems such as bulky structure, complex welding, and inconvenient operation. During long-term use, the clamping structure is susceptible to material erosion and wear, affecting its stability and service life. In addition, when dealing with some special materials or high-flow conditions, traditional clamping structures often cannot provide sufficient clamping force, which can easily lead to safety hazards such as material leakage.

[0005] Therefore, existing technologies need further development. Utility Model Content

[0006] The purpose of this utility model is to overcome the above-mentioned technical deficiencies and provide a clamping structure to solve the technical problem of low clamping efficiency of the baffle plate clamping device in related technologies.

[0007] To achieve the above technical objectives, the present invention adopts the following technical solution: A pressing structure is provided, characterized in that it includes: a mounting frame on which a rotating shaft is mounted; a pressing assembly comprising an eccentric wheel and an abutment disposed on the side of the eccentric wheel near the workpiece to be pressed, the eccentric wheel being rotatably connected to the rotating shaft, and the abutment abutting against the workpiece to be pressed; and a limiting component, one end of the limiting component near the pressing assembly abutting against a stop portion disposed on the eccentric wheel, thereby limiting relative rotation of the eccentric wheel when the abutment abuts against the workpiece to be pressed.

[0008] Furthermore, the stop includes a ratchet, which protrudes from the outer circumferential surface of the eccentric wheel. The end of the limiting member near the clamping assembly abuts against the ratchet. The limiting member is movably configured, and the ratchet includes multiple ratchets.

[0009] Furthermore, the abutment part has a recessed receiving groove, which contains an eccentric wheel.

[0010] Furthermore, the abutting component includes an abutting surface that abuts against the component to be pressed. The abutting surface is an arc-shaped surface, and the axis of the abutting surface is parallel to or coincides with the axis of the rotating shaft.

[0011] Furthermore, an eccentric hole is provided on the side of the eccentric wheel away from the abutment, and a rotating shaft is accommodated in the eccentric hole, with the rotating shaft rotatably connected to the eccentric hole.

[0012] Furthermore, the eccentric wheels include at least two, and the at least two eccentric wheels are spaced apart along the extension direction of the shaft.

[0013] Furthermore, the clamping assembly includes a handle that protrudes from the outer peripheral surface of the eccentric wheel.

[0014] Furthermore, the clamping structure includes a mounting base plate on which a mounting bracket and limiting components are mounted.

[0015] Furthermore, the mounting bracket includes: a first connecting part, one end of which is connected to the mounting base plate; a second connecting part, one end of which is connected to the first connecting part, and a rotating shaft is mounted on the other end of the second connecting part, with a preset angle between the second connecting part and the first connecting part.

[0016] Furthermore, the mounting brackets include multiple brackets, which are spaced apart along the axis of rotation.

[0017] Beneficial effects:

[0018] 1. Specifically, the mounting bracket supports the entire clamping assembly. The rotating shaft is mounted on the mounting bracket, serving as the basis for the rotation of the eccentric wheel. The eccentric wheel and the rotating shaft cooperate to form a force-saving lever structure. When the eccentric wheel rotates, its eccentric part pushes the abutment towards the part to be clamped, achieving rapid clamping. Compared to traditional bolt or welding fixing methods, the eccentric wheel structure is easier to operate and the clamping action is faster, significantly improving clamping efficiency. Using the eccentric wheel for clamping, the clamping force of the abutment against the stop plate can be adjusted by controlling the rotation angle of the eccentric wheel. The clamping force can be quickly adjusted by rotating the eccentric wheel, achieving adjustable clamping force. After the abutment completes the clamping action, the limiting component and the stop on the eccentric wheel abut against each other, forming a mechanical limit to prevent accidental rotation of the eccentric wheel and clamping failure. This limit restricts the eccentric wheel from continuing to rotate after the clamping stroke is complete, preventing loosening.

[0019] 2. The clamping structure of this embodiment is applied to a belt conveyor for clamping the baffle plate. The overall structure consists of a mounting frame, a clamping component and a limiting component. This clamping structure achieves efficient clamping through an eccentric wheel mechanism. The clamping force is adjustable. The structure is simple, the manufacturing cost is low, and the whole structure is lightweight and easy to operate, which greatly reduces maintenance costs and time. It solves the technical problem of low clamping efficiency of baffle plate clamping devices in related technologies. Attached Figure Description

[0028] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0029] According to an embodiment of this utility model, a clamping structure is provided; please refer to [link / reference]. Figures 1 to 6The device includes: a mounting bracket 1 on which a rotating shaft 2 is mounted; a clamping assembly 3, which includes an eccentric wheel 31 and an abutment 32 disposed on the side of the eccentric wheel 31 near the part to be clamped 10, the eccentric wheel 31 being rotatably connected to the rotating shaft 2, and the abutment 32 being able to abut against the part to be clamped 10; and a limiting member 4, one end of the limiting member 4 near the clamping assembly 3 abutting against a stop portion 33 disposed on the eccentric wheel 31, so as to limit the relative rotation of the eccentric wheel 31 when the abutment 32 abuts against the part to be clamped 10.

[0030] It should be noted that the extension direction of the rotating shaft 2 and the abutment 32 is consistent with the extension direction of the part to be pressed 10.

[0031] Specifically, the mounting bracket 1 supports the entire clamping assembly 3, and the rotating shaft 2 is mounted on the mounting bracket 1, serving as the basis for the rotation of the eccentric wheel 31. The eccentric wheel 31 and the rotating shaft 2 cooperate to form a force-saving lever structure. When the eccentric wheel 31 is rotated, its eccentric part pushes the abutment 32 towards the part to be clamped 10, achieving rapid clamping. Compared with traditional bolt or welding fixing methods, the eccentric wheel structure is easier to operate and the clamping action is faster, significantly improving clamping efficiency. Using the eccentric wheel for clamping, the clamping force of the abutment 32 on the stop plate can be adjusted by controlling the rotation angle of the eccentric wheel. The clamping force can be quickly adjusted by rotating the eccentric wheel, achieving adjustable clamping force. After the abutment 32 completes the clamping action, the limiting component 4 abuts against the stop part 33 on the eccentric wheel 31, forming a mechanical limit to prevent the eccentric wheel from accidentally rotating back and causing clamping failure. This is used to limit the eccentric wheel 31 from continuing to rotate after the clamping stroke is completed, preventing loosening.

[0032] The clamping structure of this embodiment is applied to a belt conveyor for clamping the baffle plate. The overall structure consists of a mounting frame 1, a clamping component 3, and a limiting component 4. This clamping structure achieves efficient clamping through an eccentric wheel mechanism. The clamping force is adjustable, the structure is simple, the manufacturing cost is low, and the whole structure is lightweight and easy to operate, which greatly reduces maintenance costs and time. It solves the technical problem of low clamping efficiency of baffle plate clamping devices in related technologies.

[0033] In the clamping structure of this embodiment, see Figure 6 The stop part 33 includes ratchet teeth, which protrude from the outer circumferential surface of the eccentric wheel 31. The end of the limiting member 4 near the clamping assembly 3 abuts against the ratchet teeth. The limiting member 4 is movably disposed, and the ratchet teeth include multiple teeth. Due to the ratchet design, when the limiting member 4 contacts a certain ratchet tooth, a mechanical locking state is formed, preventing the eccentric wheel 31 from rotating unexpectedly under the action of external forces (such as material impact), thereby ensuring the stability of the clamping structure and preventing the clamped part from loosening.

[0034] Since there are multiple ratchet teeth, the limiting component 4 can be selected to contact different ratchet teeth, providing multiple locking levels. The appropriate clamping force and locking position can be selected according to actual needs. By changing the contact point between the limiting component 4 and different ratchet teeth, the rotation angle of the eccentric wheel 31 can be finely adjusted, thereby precisely controlling the clamping force of the abutment 32 on the baffle plate.

[0035] Specifically, the end of the limiting member 4 has a shape that matches the ratchet, so that it can be fitted between two adjacent ratchets, thereby limiting the rotation of the eccentric wheel 31.

[0036] Specifically, the limiting component 4 is movably set, and the end of the limiting component 4 has a certain elasticity, so as to facilitate the release of the locking state. By manually pulling the limiting component 4, the end of the limiting component 4 can be moved away from the two ratchet teeth. At this time, the eccentric wheel 31 can be rotated to release the clamping part 10.

[0037] In some embodiments, the limiting component 4 is a long strip structure, with one end fixedly mounted on the mounting base plate 5 and the other end provided with a pawl structure that matches the shape of the ratchet. By adjusting the size of the limiting component 4, it can be made to have a certain elasticity, and can be deformed by pulling by hand, thereby releasing the part to be pressed 10.

[0038] In the clamping structure of this embodiment, see Figure 1 The abutment member 32 has a recessed receiving groove 321, which contains an eccentric wheel 31. By partially or completely accommodating the eccentric wheel 31 in the receiving groove 321 of the abutment member 32, the overall size and weight of the entire clamping device can be reduced, improving the compactness and operational stability of the entire clamping structure, making the clamping structure lightweight and easy to operate.

[0039] In some embodiments, the eccentric wheel 31 is welded into the receiving groove 321.

[0040] In the clamping structure of this embodiment, see Figure 1 or Figure 6 The abutment member 32 includes an abutment surface 322 that abuts against the part to be pressed 10. The abutment surface 322 is an arc-shaped surface, and the axis of the abutment surface 322 is parallel to or coincides with the axis of the rotating shaft 2. In this way, the arc-shaped surface design of the abutment member 32 allows it to slide against the part to be pressed 10, reducing wear and friction, improving adaptability and operational flexibility, making the contact between the abutment member 32 and the part to be pressed 10 more uniform. The arc-shaped surface can better adapt to the different shapes of the parts to be pressed 10. The shape of the abutment surface 322 is adapted to the eccentric wheel, so that it cooperates with the eccentric wheel, and the eccentric part formed by the eccentric wheel 31 and the abutment member 32 pushes the abutment member 32 toward the part to be pressed 10.

[0041] In some embodiments, the cross-section of the abutment 32 is semi-circular or fan-shaped.

[0042] Preferably, the center line of the abutment 32 is collinear with the center line of the eccentric wheel 31, that is, the center line of the abutment 32 is collinear with the longest radius of the eccentric wheel.

[0043] In the clamping structure of this embodiment, see Figure 1 An eccentric hole 311 is provided on the side of the eccentric wheel 31 away from the abutment member 32. The eccentric hole 311 contains a rotating shaft 2, which is rotatably connected to the eccentric hole 311. By providing the eccentric hole 311, the rotating shaft 2 can be easily installed and disassembled, and the clamping structure can be easily maintained.

[0044] In the clamping structure of this embodiment, see Figure 4-5 The eccentric wheel 31 includes at least two eccentric wheels 31, which are spaced apart along the extension direction of the rotating shaft 2. By setting at least two eccentric wheels 31, the weight and load of the clamping assembly 3 can be distributed more evenly. This not only improves the structural stability of the entire system, but also provides more stable support for the clamping assembly 3, allowing the clamping assembly 3 to apply clamping force over a wider range.

[0045] Preferably, the eccentric wheel 31 comprises two.

[0046] In the clamping structure of this embodiment, see Figure 1 The clamping assembly 3 includes a handle 34, which protrudes from the outer circumferential surface of the eccentric wheel 31. This design of the handle 34 allows the user to directly rotate the eccentric wheel 31 by hand without the need for additional tools (such as wrenches or screwdrivers), greatly improving the convenience and efficiency of operation. Especially when frequent adjustments to the clamping force are required, by gripping and rotating the handle 34, the position of the eccentric wheel 31 can be quickly adjusted, enabling rapid adjustment of the pressure between the abutment 32 and the part to be clamped, thus simplifying the operation process.

[0047] See Figure 3 Pulling the handle 34 upwards causes the eccentric wheel 31 to rotate counterclockwise, moving the end of the abutment 32 away from the part to be clamped 10, thus releasing the part to be clamped 10. Pulling the handle 34 downwards causes the eccentric wheel 31 to move clockwise, bringing the end of the abutment 32 closer to the part to be clamped 10, thus clamping the part to be clamped.

[0048] In the clamping structure of this embodiment, see Figure 1 The clamping structure includes a mounting base plate 5, on which a mounting bracket 1 and a limiting component 4 are mounted. Specifically, when the abutting member 32 abuts against the member to be clamped 10, the member to be clamped 10 is clamped between the abutting member 32 and the mounting base plate 5.

[0049] In the clamping structure of this embodiment, see Figure 1 The mounting bracket 1 includes: a first connecting part 11, one end of which is connected to the mounting base plate 5; and a second connecting part 12, one end of which is connected to the first connecting part 11, and the other end of which is fitted with a rotating shaft 2. A preset angle is provided between the second connecting part 12 and the first connecting part 11. By setting the mounting bracket 1 to support the rotating shaft, it can indirectly support the clamping assembly 3, further increasing the fixing strength of the rotating shaft. By adjusting the preset angle between the first connecting part 11 and the second connecting part 12, the tilt angle of the entire mounting bracket 1 can be flexibly adjusted according to actual needs, thereby adjusting the installation angle of the clamping assembly 3, making the operation more intuitive and convenient, and avoiding the situation where the clamping structure is difficult to operate due to the tilt of the mounting base plate 5. In addition, by adjusting the angle between the two connecting parts, a more compact equipment layout can be achieved in a limited space, which is particularly suitable for occasions with limited installation space.

[0050] In some embodiments, a portion of the abutment 32 is accommodated between the second connecting portion 12 and the mounting base plate 5, and therefore a clearance hole is provided on the mounting bracket 1 to avoid the abutment 32.

[0051] In the clamping structure of this embodiment, see Figure 1 The mounting bracket 1 comprises multiple brackets, which are spaced apart along the axis of the rotating shaft 2. Multiple mounting brackets 1 can more evenly distribute the weight and workload of the entire system, preventing any single mounting bracket from bearing excessive pressure. This not only improves the overall stability of the system.

[0052] In some embodiments, see Figure 1 The two ends of the rotating shaft 2 are fixedly installed on the mounting base plate 5 to further prevent the rotating shaft 2 from rotating relative to each other.

[0053] The clamping structure of this embodiment is applied to a belt conveyor to clamp the retaining rubber plate. A set of identical clamping structures is configured on both sides of the belt conveyor's guide chute to prevent the rubber plate from loosening. This ensures that operation can be completed manually by only one person, with reliable operation and increased operational stability of the guide chute mechanism. This clamping structure has the advantages of simple operation, convenient and flexible installation, and labor-saving overall movement, effectively reducing labor intensity and preventing damage. The clamping components 3, such as the eccentric wheel, are not welded to the frame, facilitating replacement and improving the overall structural stability. Furthermore, the device features an adjustable clamping force design, allowing for convenient clamping force adjustment and significantly improving work efficiency. The locking method using a ratchet and limiting component 4 makes the clamping process more stable and reliable, improving the overall safety factor and extending the equipment's service life.
