Description

Technical Field

[0001] The invention relates to the technical field of air-floating conveyor belts, in particular to an adaptive anti-eccentric load structure applied to air-floating conveyor belts. Background Art

[0002] As an efficient material conveying equipment, air-floating conveyor belts have been widely used in many fields such as food, medicine, and electronics due to their low-friction and high-precision conveying characteristics. The working principle is to pass compressed air into the bottom of the conveyor belt to form an air-floating layer between the conveyor belt and the supporting structure, thereby achieving suspension and low-resistance operation of the conveyor belt, improving conveying efficiency and reducing wear.

[0003] In existing technologies, when materials accumulate locally during transportation due to placement errors or their own flow characteristics, the supporting platform tends to deviate laterally. As the displacement gradually accumulates during transportation, it is easy for the edge of the supporting platform to continuously scrape against the equipment frame. This not only causes surface wear and edge deformation of the platform, but can also cause airflow disturbances in the air flotation layer, further exacerbating transportation instability.

[0004] Moreover, since the materials are naturally flattened by their own gravity after being put into the equipment, granular, blocky and other materials with poor fluidity are very likely to form local aggregations on the carrying platform. The uneven distribution of the materials will cause the unbalanced stress state of the flotation components, resulting in periodic fluctuations in the blower output pressure. Long-term operation will cause the blower motor to overload and the air holes on the surface of the drive plate to be locally blocked or worn due to uneven airflow impact. This will not only increase the maintenance frequency and cost of the equipment, but also reduce the conveying efficiency due to frequent fluctuations in operating parameters, shorten the actual service life of the core components of the flotation system, and have a significant impact on the overall operation. Summary of the Invention

[0005] The object of the present invention is to provide an adaptive anti-eccentric load structure for an air-floating conveyor belt, so as to solve the problems mentioned in the above background technology.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an adaptive anti-eccentric load structure applied to an air-floating conveyor belt, comprising a mounting frame, a feed hopper for placing materials fixedly mounted on one side of the top of the mounting frame, and a placement plate placed on the top of the mounting frame, the placement plate being used to place the materials to be transported;

[0007] An air flotation component for suspending the placement plate is installed on the outside of the mounting frame, a lateral correction component for correcting the placement plate is installed on the bottom of the mounting frame, and a material shifting component for evenly smoothing the material on the surface of the placement plate is installed on the outside of the mounting frame.

[0008] Furthermore, the air flotation assembly includes a driving plate installed on the inner side of the mounting frame, a plurality of air holes are provided on the outer surface of the driving plate, and a plurality of blowers are installed on the outside of the mounting frame.

[0009] Furthermore, the lateral correction assembly includes a transmission shaft, which is movably connected to the inner side of the mounting frame through a bearing, a driving motor for rotating the mounting frame is installed on the outer side of the mounting frame, a plurality of bevel gears are fixed on the outer side of the transmission shaft, and the bottom of the drive plate is fixedly connected to multiple groups of support frames.

[0010] Furthermore, the inner side of the support frame is movably connected to a bevel gear 2 that is meshed with the bevel gear 1 through a bearing, the top of the bevel gear 2 is fixedly connected to a rotating disk through a rotating shaft, the outer eccentric part of the rotating disk is rotatably connected to two connecting rods, and one end of the connecting rod is movably connected to a correction frame.

[0011] Furthermore, connecting frames are fixedly connected to both sides of the top of the mounting frame, and multiple groups of through holes are provided on the inner side of the connecting frame. The inner walls of the through holes are slidably connected to the outer side of the correcting frame.

[0012] Furthermore, the material-dipping assembly includes a plurality of driving gears movably connected to one side of the mounting frame through bearings, the outer sides of the driving gears are meshedly connected to two racks 1, the outer sides of the racks 1 are fixedly connected to support bars, the tops of the support bars are installed with electric telescopic rods, and the output ends of the electric telescopic rods are fixedly connected to material-dipping plates.

[0013] Furthermore, a screw is rotatably mounted on one side of the mounting frame, a driving motor for rotating the screw is mounted on one side of the mounting frame, and the external thread of the screw is connected to two threaded sleeves.

[0014] Furthermore, the outer side of the threaded sleeve is fixedly connected to the outer side of the rack 1 at the bottom, and the rack 1 is slidably connected to the outer side of the mounting frame.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. The present invention provides a lateral correction component, which can achieve accurate and efficient correction when the placement plate is overloaded. When the placement plate is overloaded due to uneven material distribution, the driving motor drives the transmission shaft to rotate, and the bevel gear one and the bevel gear two rotate synchronously, thereby driving the rotating disk to rotate coaxially. The eccentric structure of the rotating disk converts the rotational motion into linear motion of the correction frame through the connecting rod, so that the correction frame moves in the opposite direction of the overload of the placement plate. This directional correction force can quickly offset the overload trend of the placement plate, ensuring that the placement plate returns to the normal conveying position in a short time, effectively avoiding the placement plate from colliding or rubbing with other parts of the equipment due to continuous overload, and significantly improving the stability of the air-floating conveyor belt during operation.

[0017] 2. When the material on the placement plate needs to be processed, the drive motor drives the screw to rotate, so that the two threaded sleeves outside the screw move along the axial direction of the screw, and the threaded sleeve drives the bottom rack 1 to move synchronously, and the drive gear engaged with the rack 1 rotates accordingly, thereby driving the top rack 1 to move in the opposite direction. The reverse movement causes the support bars on both sides to drive the electric telescopic rod and the material stripping plate to move back and forth. The electric telescopic rod adjusts the height of the material stripping plate according to the thickness of the material so that it accurately contacts the surface of the material. The material stripping plate evenly smoothes the material during the reciprocating movement, and disperses the accumulated material to the vacant area, effectively optimizing the distribution of the material on the placement plate, and fundamentally reducing the overloading problem caused by uneven material distribution. This not only reduces the workload of the lateral correction component, but also reduces the wear of the air flotation component caused by continuous overloading. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] Example 1: Figure 1-Figure 7 As shown, the adaptive anti-eccentric load structure applied to the air-floating conveyor belt includes a mounting frame 1, a placement plate 3 is placed on the top of the mounting frame 1, and the placement plate 3 is used to place the material to be transported. A feed hopper 4 is fixedly installed on one side of the top of the mounting frame 1, and the feed hopper 4 is used to place the material on the placement plate 3. The feed hopper 4 serves as a material inlet device for guiding the material to be transported to the placement plate 3;

[0029] An air flotation component is installed on the outside of the mounting frame 1, and the air flotation component is used to suspend the placement plate 3. A lateral correction component is installed on the bottom of the mounting frame 1. When the placement plate 3 is overloaded, the executive component of the lateral correction component moves in the opposite direction of the overload of the placement plate 3 to achieve the correction of the placement plate 3. A material shifting component is installed on the side of the mounting frame 1, and the material shifting component is used to evenly smooth the material on the placement plate 3 to avoid uneven distribution of the material.

[0030] The placement plate 3 is a material-carrying platform. During the conveying process, the material is placed on its upper surface and is suspended and transported by the action of the flotation component. The flotation component is installed on the outside of the mounting frame 1. Its main function is to use the air flow to form an air flotation layer, so that the placement plate 3 can be suspended above the driving plate 202, which significantly reduces the friction during the conveying process, improves the conveying efficiency and reduces mechanical wear.

[0031] The air flotation assembly includes a drive plate 202 mounted on the inner side of the mounting frame 1. The outer surface of the drive plate 202 is provided with multiple groups of air holes 203. The outer surface of the mounting frame 1 is provided with multiple groups of blowers 201. When the blowers 201 are started, they generate high-pressure gas in cooperation with the drive plate 202. The gas is ejected through the air holes 203 to form an air flotation layer.

[0032] This allows the placement plate 3 to levitate, supported by the air flotation layer, reducing friction and achieving efficient, low-resistance material transport. When the airflow changes direction, the placement plate 3 can smoothly adjust the conveying direction. The drive plate 202 is mounted inside the mounting frame 1 and cooperates with the air flotation assembly. The air holes 203 are evenly distributed on its surface, allowing high-pressure gas to be evenly ejected, forming a stable air flotation layer.

[0033] The lateral correction component includes a transmission shaft 601, which is movably connected to the inner side of the mounting frame 1 through a bearing. A driving motor for rotating the mounting frame 1 is installed on the outer side of the mounting frame 1. A plurality of bevel gears 603 are fixedly sleeved on the outer side of the transmission shaft 601. The bottom of the driving plate 202 is fixedly connected to a plurality of support frames 602. The inner side of the support frame 602 is movably connected to a bevel gear 2 604 meshing with the bevel gear 1 603 through a bearing. The top of the rotating shaft is fixedly connected to a rotating disk 605. The outer eccentric part of the rotating disk 605 is rotatably connected to two connecting rods 606. One end of the connecting rod 606 is movably connected to a correction frame 607. The top two sides of the mounting frame 1 are fixedly connected to a connecting frame 7. The inner side of the connecting frame 7 is provided with a plurality of through holes. The inner wall of the through hole is slidably connected to the outer side of the correction frame 607.

[0034] During the specific setting, when the placement plate 3 is under an overload condition, the overload causes the placement plate 3 to generate a lateral force on the lateral correction component. At this time, the motor starts and drives the transmission shaft 601 to rotate. The rotation of the transmission shaft 601 drives the bevel gear 1 603 to rotate synchronously. The bevel gear 1 603 and the bevel gear 2 604 are meshed with each other. The bevel gear 2 604 starts to rotate under the drive of the bevel gear 1 603, and the rotation direction is perpendicular to the rotation direction of the bevel gear 1 603, thereby realizing the change of the movement direction. The rotation of the bevel gear 2 604 drives the rotating disk 605 fixed to it to rotate together, and the rotational motion of the rotating disk 605 is converted into reciprocating swinging through the connecting rod 606;

[0035] As the rotating disk 605 rotates, one end of the connecting rod 606 makes a circular motion around the center of the rotating disk 605, causing the connecting rod 606 to swing. Under the traction of the connecting rod 606, the correcting frame 607 moves in the direction opposite to the overload of the placement plate 3. The movement of the correcting frame 607 is guided by the through hole on the inner side of the connecting frame 7 to ensure the accuracy of its movement direction, thereby realizing the correction of the placement plate 3 until the placement plate 3 returns to normal and is transported stably.

[0036] Example 2: The material prying assembly includes a plurality of driving gears 502 movably connected to one side of the mounting frame 1 through bearings. The outer sides of the driving gears 502 are meshedly connected to two racks 501. The outer sides of the racks 501 are fixedly connected to support bars 503. The top of the support bars 503 is installed with an electric telescopic rod 504. The output end of the electric telescopic rod 504 is fixedly connected to the material prying plate 505.

[0037] When the material needs to be leveled, the electric telescopic rod 504 drives the material stripping plate 505 to move downward to the material surface. After the leveling is completed, the electric telescopic rod 504 drives the material stripping plate 505 to separate from the material surface and prepare for the next leveling operation. The material stripping plate 505 is in direct contact with the material and evenly levels the material on the placement plate 3 through its own reciprocating movement, avoiding the unbalanced loading phenomenon caused by uneven material distribution and optimizing the material distribution.

[0038] A screw rod 506 is rotatably installed on one side of the mounting frame 1, and a driving motor for rotating the screw rod 506 is installed on one side of the mounting frame 1. The external thread of the screw rod 506 is connected to two threaded sleeves 507, and the outer side of the threaded sleeve 507 is fixedly connected to the outer side of the rack 1 501 at the bottom, and the rack 1 501 is slidably connected to the outer side of the mounting frame 1.

[0039] Combining the first and second embodiments, it can be seen that the working principle of the present invention is as follows:

[0040] The material is evenly fed to the upper surface of the placement plate 3 through the feed hopper 4, and the blower 201 is started to generate high-pressure gas with the cooperation of the driving plate 202, forming an air flotation layer through the air holes 203, so that the placement plate 3 can be suspended under the action of the air flotation layer, and the material on the placement plate 3 can be smoothly transported as the direction of the air flow changes.

[0041] When the placement plate 3 is overloaded, the transmission shaft 601 rotates under the drive of the motor, and further drives the bevel gear 1 603 to rotate synchronously. The rotation of the bevel gear 2 604 further drives the rotating disk 605 connected to it to rotate coaxially. The rotation of the rotating disk 605 causes one end of the connecting rod 606 to swing. Since the other end of the connecting rod 606 is movably connected to the correction frame 607, under the traction of the connecting rod 606, the correction frame 607 moves in the direction opposite to the overload of the placement plate 3, thereby correcting the placement plate 3 and ensuring that it returns to normal and is transported stably.

[0042] At the same time, the screw 506 rotates under the drive of the motor, and further drives the two threaded sleeves 507 to move along the outside of the screw 506. During the movement, the threaded sleeve 507 further drives the rack 1 501 to move synchronously. When the rack 1 501 and the driving gear 502 are engaged with each other, the driving gear 502 rotates synchronously under the drive of the rack 1 501, prompting it to drive the top rack 1 501 to move in the opposite direction of the bottom rack 1 501. Then the electric telescopic rod 504 is started, and the output end of the electric telescopic rod 504 drives the material stripping plate 505 to move downward. The material stripping plate 505 evenly smoothes the material on the placement plate 3 to avoid overloading caused by uneven material distribution.
