Description

Technical Field

[0001] This utility model relates to the field of conveying device technology, and in particular to a roller conveyor device. Background Technology

[0002] A roller conveyor is a device used for material transport. It conveys materials by rotating rollers. Due to its low maintenance costs and high conveying efficiency, roller conveyors are widely used in modern industrial production and logistics transportation.

[0003] In the operation of traditional roller conveyors, materials are transported solely by the rolling of the rollers, lacking limiting measures. When materials are transported from the output end of the roller conveyor to the downstream end, due to the smooth surface and irregular shape of the materials, they can easily roll off the rollers and bounce downstream, causing material damage and affecting the stable transport of materials by the roller conveyor.

[0004] Therefore, there is a need to provide a roller conveyor device to solve the above problems. Utility Model Content

The mounting frame is connected to the conveyor frame, and the limiting component is slidably connected to the mounting frame along the Z-axis. The elastic element extends along the Z-axis, and its two ends are respectively connected to the limiting component and the mounting frame. When the material is conveyed along the conveyor roller, the material can push the limiting component to move upward along the Z-axis so that the material is conveyed below the limiting component. The elastic element can drive the limiting component to press against the material.

[0011] Preferably, the limiting component includes:

[0012] A connecting rod extends along the Z-axis direction and is slidably inserted into the mounting frame;

[0013] A connecting plate is disposed at the end of the connecting rod away from the conveying roller, and the connecting plate can abut against the mounting frame;

[0014] A pressure block is disposed at one end of the connecting rod facing the conveying roller, and the two ends of the elastic element are respectively connected to the pressure block and the mounting frame.

[0015] Preferably, the pressing block has a pressing surface and a guiding surface. When the material is conveyed along the conveying direction, it can slide along the guiding surface to drive the pressing block to move upward along the Z-axis direction. The pressing surface can press against the material.

[0016] Preferably, the roller conveyor further includes two second limiting mechanisms, which are disposed on both sides of the conveyor frame along the X-axis direction. The second limiting mechanisms include:

[0017] A guide baffle is disposed on the side of the conveyor frame facing the conveyor roller, extending from top to bottom along the Z-axis toward the centerline of the conveyor frame.

[0018] Preferably, the second limiting mechanism further includes:

[0019] A baffle assembly is disposed above the conveyor frame, and the height of the baffle assembly is adjustable along the Z-axis.

[0020] Preferably, the baffle assembly includes:

[0021] A first baffle is disposed on the conveyor frame;

[0022] A screw extends along the Z-axis and is fixedly connected to the conveyor frame;

[0023] The second baffle includes a first plate and a second plate that are vertically connected. The first plate is slidably disposed on one side of the first baffle. A threaded sleeve is rotatably connected to the second plate. The threaded sleeve extends along the Z-axis and is threadedly connected to the screw.

[0024] Preferably, the conveyor rack includes:

[0025] Base plate;

[0026] Two side plates are disposed on both sides of the base plate along the X-axis direction;

[0027] Two support blocks are spaced apart along the Y-axis and supported at the bottom end of the base plate.

[0028] Preferably, the base plate has a clearance opening, and the conveyor frame further includes:

[0029] A pull-out assembly, including a receiving space, is slidably disposed on the base plate.

[0030] Preferably, the driving component includes:

[0031] A drive belt, through which multiple conveyor rollers are connected for transmission;

[0032] A drive unit for driving one of the conveyor rollers to rotate.

[0033] Preferably, the conveying roller engages with the transmission belt.

[0034] The beneficial effects of this utility model are:

[0035] This roller conveyor includes a conveyor frame, multiple conveyor rollers, a drive assembly, and a first limiting mechanism. The conveyor frame extends along the Y-axis, and the multiple conveyor rollers are spaced apart along the Y-axis and rotatably connected to the conveyor frame. The drive assembly is configured to drive the multiple conveyor rollers to rotate. At least one end of the conveyor frame is provided with a first limiting mechanism, which includes a mounting frame, an elastic element, and a limiting assembly. The mounting frame is connected to the conveyor frame, and the limiting assembly is slidably connected to the mounting frame along the Z-axis. The elastic element extends along the Z-axis, and its two ends are respectively connected to the limiting assembly and the mounting frame. When material is conveyed along the conveyor rollers, the material can push the limiting assembly to move upward along the Z-axis, so that the material is conveyed to the bottom of the limiting assembly, and the elastic element can drive the limiting assembly to press against the material.

[0036] The drive assembly can drive multiple conveyor rollers to rotate. When material is placed on this roller conveyor, the conveyor rollers rotate to move the material along the Y-axis towards the conveying end. When the material approaches the end of the conveyor frame, it contacts the limiting component of the first limiting mechanism. Due to the thrust of the material, the limiting component slides upward along the Z-axis, and the elastic element is compressed. When the material is completely below the limiting component, the elastic force of the elastic element causes the limiting component to move downward along the Z-axis to press against the material, preventing the material from rolling or jumping due to its smooth surface or irregular shape during the conveying process from the conveying end to the downstream. This roller conveyor, through the elastic pressing action of the first limiting mechanism, can effectively prevent the material from rolling or jumping during the conveying process from the conveying end to the downstream, ensuring stable conveying of the material on the roller conveyor, allowing the material to reach the downstream according to a predetermined path and speed, improving the stability of the conveying, and reducing the risk of material damage. Under the elastic action of the elastic element, the first limiting mechanism can automatically adapt to materials of various heights to stably press against the material, showing strong adaptability and good versatility.

[0048] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0049] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0050] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0051] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0052] In the operation of traditional roller conveyors, materials are transported solely by the rolling of the rollers, lacking limiting measures. When materials are transported from the output end of the roller conveyor to the downstream end, due to the smooth surface and irregular shape of the materials, they can easily roll off the rollers and bounce downstream, causing material damage and affecting the stable transport of materials by the roller conveyor.

[0053] like Figures 1-4As shown, this embodiment provides a roller conveyor device, which includes a conveyor frame 1, a plurality of conveyor rollers 2, a drive assembly 3, and a first limiting mechanism. The conveyor frame 1 extends along the Y-axis direction, and the plurality of conveyor rollers 2 are spaced apart along the Y-axis direction and are rotatably connected to the conveyor frame 1. The drive assembly 3 is configured to drive the plurality of conveyor rollers 2 to rotate. At least one end of the conveyor frame 1 is provided with a first limiting mechanism, which includes a mounting frame 41, an elastic element 42, and a limiting assembly 43. The mounting frame 41 is connected to the conveyor frame 1, and the limiting assembly 43 is slidably connected to the mounting frame 41 along the Z-axis direction. The elastic element 42 extends along the Z-axis direction, and both ends of the elastic element 42 are connected to the limiting assembly 43 and the mounting frame 41, respectively. When the material is conveyed along the conveyor rollers 2, the material can push the limiting assembly 43 to move upward along the Z-axis direction so that the material is conveyed to the bottom of the limiting assembly 43. The elastic element 42 can drive the limiting assembly 43 to press against the material.

[0054] The drive assembly 3 can drive multiple conveying rollers 2 to rotate. When the material is placed on this roller conveyor, the conveying rollers 2 rotate to move the material along the Y-axis towards the conveying end. When the material approaches the end of the conveying frame 1, the material will contact the limiting assembly 43 of the first limiting mechanism. Due to the pushing force of the material, the limiting assembly 43 slides upward along the Z-axis, and the elastic element 42 is compressed. When the material is completely below the limiting assembly 43, the elastic force of the elastic element 42 causes the limiting assembly 43 to move downward along the Z-axis to press against the material, preventing the material from rolling or jumping due to its smooth surface or irregular shape during the process of being conveyed from the conveying end to the downstream. This roller conveyor device, through the elastic pressing action of the first limiting mechanism, can effectively prevent materials from rolling or jumping when conveyed from the conveying end to the downstream, ensuring the stable conveying of materials on the roller conveyor device, enabling materials to reach the downstream according to the predetermined path and speed, improving the stability of conveying, and reducing the risk of material damage. Under the elastic action of the elastic element 42, the first limiting mechanism can automatically adapt to materials of various heights to stably press them onto the materials, showing strong adaptability and good versatility.

[0055] In some embodiments, a first limiting mechanism is provided at one end of the conveyor frame 1. In this case, the end with the first limiting mechanism serves as the output end of the roller conveyor device; in other embodiments, such as Figure 1 As shown, the conveyor frame 1 is equipped with a first limiting mechanism at both ends. When the conveying direction changes, the first limiting mechanism at both ends of the conveyor frame 1 can play a limiting role to ensure the stability and safety of material conveying.

[0056] Optionally, such as Figure 2As shown, the limiting component 43 includes a connecting rod 431, a connecting plate 432, and a pressure block 433. The connecting rod 431 extends along the Z-axis and can slide through the mounting frame 41. The connecting plate 432 is located at the end of the connecting rod 431 away from the conveying roller 2 and can abut against the mounting frame 41. The pressure block 433 is located at the end of the connecting rod 431 facing the conveying roller 2. The two ends of the elastic member 42 are connected to the pressure block 433 and the mounting frame 41, respectively.

[0057] like Figure 1 , Figure 2 As shown, in the initial state, the connecting rod 431 passes through the mounting frame 41 along the Z-axis, the connecting plate 432 is located above the mounting frame 41, and the pressure block 433 is located below the mounting frame 41. The two ends of the elastic element 42 are connected to the pressure block 433 and the mounting frame 41 respectively. The elastic element 42 is in a naturally extended state, and the pressure block 433 is suspended above the conveying roller 2 under the tension of the elastic element 42. When the material is conveyed by the conveying roller 2 and approaches the limiting component 43, the material exerts an upward thrust on the pressure block 433 along the Z-axis. The pressure block 433 drives the entire limiting component 43 to slide upward along the Z-axis through the connecting rod 431. When the material is below the pressure block 433, the elastic force of the elastic element 42 causes the connecting rod 431 and the pressure block 433 to move downward along the Z-axis. The pressure block 433 presses against the material to prevent the material from rolling or jumping during the conveying process due to its smooth surface or irregular shape.

[0058] Among them, the elastic element 42 is a spring.

[0059] It should be noted that the number of connecting rods 431 is determined according to actual needs, and multiple connecting rods 431 are spaced apart along the X-axis. The arrangement of multiple connecting rods 431 makes the limiting component 43 more stable when moving along the Z-axis, preventing wobbling. For example, such as... Figure 1 , Figure 2 As shown, in this embodiment, there are two connecting rods 431.

[0060] Optionally, such as Figure 2 As shown, the pressure block 433 has a pressing surface 4331 and a guiding surface 4332. When the material is conveyed along the conveying direction, it can slide along the guiding surface 4332 to drive the pressure block 433 to move upward along the Z-axis. The pressing surface 4331 can press against the material. The guiding surface 4332 can guide the material to move upward along the Z-axis when it moves along the conveying direction, so that the material will not be blocked by the pressure block 433 and can be smoothly conveyed downward along the conveying direction, ensuring the stability of the conveying. After the material passes through the guiding surface 4332, the pressing surface 4331 can press against the material to prevent the material from rolling or jumping.

[0061] In this embodiment, the pressure block 433 is an inverted trapezoidal block. At this time, the end face of the inverted trapezoidal block facing the conveying roller 2 is the pressing surface 4331, and one of the two sides of the inverted trapezoidal block is the guide surface 4332.

[0062] In one alternative embodiment, such as Figures 1-3 As shown, this roller conveyor device also includes two second limiting mechanisms 5, which are disposed on both sides of the conveyor frame 1 along the X-axis. Each second limiting mechanism 5 includes a guide baffle 51, which is located on the side of the conveyor frame 1 facing the conveyor roller 2, extending downwards along the Z-axis towards the centerline of the conveyor frame 1. During material conveying, due to factors such as the rotation of the conveyor roller 2, the irregular shape of the material itself, or slight external disturbances, the material may deviate along the X-axis of the conveyor frame 1. When the material tends to deviate along the X-axis, it will first contact the guide baffle 51, which will prevent the material from deviating along the X-axis, ensuring that the material always runs on the predetermined conveying path. Furthermore, because the guide baffle 51 is inclined, when the material deviates along the X-axis and falls onto the guide baffle 51, the guide baffle 51 can guide the material back to the surface of the conveyor roller 2, reducing the risk of material deviation or even falling during conveying.

[0063] Specifically, such as Figure 3 As shown, the guide baffle 51 includes a mounting part 511 and a guide part 512. The mounting part 511 is fixedly connected to the top of the conveyor frame 1. The guide part 512 is located on the side of the conveyor frame 1 facing the conveyor roller 2 and extends towards the center line of the conveyor frame 1 along the Z-axis from top to bottom.

[0064] Optionally, such as Figures 1-3 As shown, the second limiting mechanism 5 also includes a baffle assembly 52, which is disposed above the conveyor frame 1. The height of the baffle assembly 52 is adjustable along the Z-axis. By setting the baffle assembly 52, the material conveyed on the conveyor roller 2 can be limited along the X-axis, preventing the material from falling along the X-axis. The height of the baffle assembly 52 is adjustable, and the height of the baffle assembly 52 can be adjusted according to the specifications of the material, making the height of the baffle assembly 52 more suitable.

[0065] In one alternative embodiment, such as Figure 2 , Figure 3As shown, the baffle assembly 52 includes a first baffle 521, a screw 522, and a second baffle 523. The first baffle 521 is disposed on the conveyor frame 1. The screw 522 extends along the Z-axis and is fixedly connected to the conveyor frame 1. The second baffle 523 includes a first plate 5231 and a second plate 5232 that are vertically connected. The first plate 5231 is slidably disposed on one side of the first baffle 521. A threaded sleeve 524 is rotatably connected to the second plate 5232. The threaded sleeve 524 extends along the Z-axis and is threadedly connected to the screw 522. The first baffle 521 is fixedly mounted on the conveyor frame 1. The second baffle 523 consists of a first plate 5231 and a second plate 5232 arranged vertically. The first plate 5231 is slidably disposed on one side of the first baffle 521, meaning that the first plate 5231 can slide relative to the first baffle 521 in the Z-axis direction. A threaded sleeve 524 is rotatably connected to the second plate 5232. The threaded sleeve 524 extends in the Z-axis direction and is threadedly connected to the screw 522. When it is necessary to adjust the height of the second baffle 523, the operator rotates the threaded sleeve 524. Since the screw 522 is fixed, according to the principle of threaded transmission, the threaded sleeve 524 will move in the Z-axis direction to change the height of the second baffle 523, thereby changing the height of the baffle assembly 52.

[0066] Optionally, such as Figure 1 As shown, the conveyor frame 1 includes a base plate 11, two side plates 12, and two support blocks 13. The two side plates 12 are arranged on both sides of the base plate 11 along the X-axis direction; the two support blocks 13 are spaced apart on the bottom end of the base plate 11 along the Y-axis direction. At this time, the two ends of the conveyor roller 2 are rotatably connected to the two side plates 12.

[0067] Furthermore, such as Figure 1 , Figure 3 As shown, the base plate 11 has a clearance opening, and the conveyor frame 1 also includes a pull-out assembly 6. The pull-out assembly 6 includes a receiving space 61 and is slidably mounted on the base plate 11. During normal material conveying, the pull-out assembly 6 is in a retracted state, and its receiving space 61 is located below the clearance opening, so it does not affect the normal conveying of materials on the conveyor roller 2. When materials fall during conveying, they will fall directly into the receiving space 61 of the pull-out assembly 6 through the clearance opening on the base plate 11. Due to the existence of the clearance opening, a channel is provided for the falling materials, and the receiving space 61 of the pull-out assembly 6 serves to receive the materials. At this time, the operator only needs to pull out the pull-out assembly 6 to easily remove the fallen materials without having to perform complicated cleaning operations in the narrow space below the conveyor frame 1.

[0068] In this embodiment, as Figure 3As shown, the pull-out assembly 6 also includes a pull-out member 62 and T-shaped protrusions 63. Two T-shaped protrusions 63 are disposed on both sides of the pull-out member 62 along the Y-axis direction. The base plate 11 has corresponding slots on both sides along the Y-axis direction. The slots extend along the X-axis direction, and the two T-shaped protrusions 63 are slidably engaged in the slots.

[0069] Optionally, such as Figure 4 As shown, the drive assembly 3 includes a transmission belt 31 and a drive component. Multiple conveying rollers 2 are connected via the transmission belt 31. The drive component drives one of the conveying rollers 2 to rotate. The multiple conveying rollers 2 are connected via the transmission belt 31. When the drive component drives one conveying roller 2 to rotate, the transmission belt 31 drives the other conveying rollers 2 to rotate synchronously. This synchronous transmission method ensures that the material maintains a stable speed and posture during conveying, avoiding material accumulation, displacement, or damage due to inconsistent rotational speeds of the conveying rollers 2.

[0070] Optionally, the conveyor roller 2 is engaged with the transmission belt 31. Compared with the ordinary transmission belt and conveyor roller connection method that relies solely on friction for transmission, the engagement can greatly reduce the occurrence of slippage of the transmission belt 31, so that the power can be transmitted to each conveyor roller 2 more directly and stably, ensuring that the conveyor roller 2 rotates stably at the set speed and ensuring the smoothness of material conveying.

[0071] In this embodiment, as Figure 4 As shown, a transmission wheel 21 is provided at the end of the conveyor roller 2. The transmission wheel 21 includes two transmission parts arranged side by side. Several transmission teeth are spaced apart on the outer periphery of the transmission parts. For ease of description, the two transmission parts are named the first transmission part 211 and the second transmission part 212. The first transmission part 211 of the transmission wheel 21 of one conveyor roller 2 is connected to the second transmission part 212 of the upstream conveyor roller 2 via a transmission belt 31. The second transmission part 212 of the transmission wheel 21 of one conveyor roller 2 is connected to the first transmission part 211 of the downstream conveyor roller 2 via a transmission belt 31. A drive wheel 32 is provided at the output end of the drive member. The first transmission part 211 of the first conveyor roller 2 is connected to the drive wheel 32 via a transmission belt 31. The drive member drives the drive wheel 32 to rotate, and the drive wheel 32 drives the first conveyor roller 2 to rotate. The first conveyor roller 2 drives the next conveyor roller 2 to rotate, and so on. This connection method makes the power transmission between multiple conveyor rollers 2 more continuous and reduces the accumulation of transmission errors.

Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
