Description

Technical Field

[0001] This utility model relates to the field of material conveying technology, and in particular to an improved turning conveyor device. Background Technology

[0002] In material conveying systems, to meet the need for material conveying and turning in complex production or warehousing environments, turning conveyor belts have emerged on the market. Existing turning conveyor belts generally use belts to transport materials. The bearing housings rotatably connect the two ends of the drive drum to the frame. By rotating the drive drum, the belt is driven to move by the friction generated between the drive drum and the belt. This results in the drawbacks of existing belt conveyors, such as poor load-bearing capacity and large inner diameter of the conveyor belt.

[0003] For example, the Chinese utility model patent with announcement number CN222137752U describes a 90-degree turning machine belt conveyor. The structure of the conveyor belt is that multiple sets of transmission rollers are assembled on the mounting frame, and a transmission belt is sleeved on the outer wall of the transmission roller. The rotation of the first transmission gear at the output end of the first servo motor can drive the transmission roller to rotate through the first transmission rack belt, and the rotation of the transmission roller can drive the transmission belt to rotate.

[0004] If the conveyor belt is carrying too much material, it is prone to slippage on the drive roller due to insufficient friction between the belt and the drive roller, which will prevent the material from being transported normally and will also cause the belt surface to wear more quickly.

[0005] Secondly, in order to maintain the tension of the transmission belt, both ends of the drive roller of the belt conveyor need to be rotatably mounted on the mounting frame via bearing seats. This results in a relatively large inner diameter of the belt conveyor, making it unsuitable for compact conveyor belt arrangements. Therefore, there is still room for improvement in existing curved conveyor belts. Summary of the Invention

[0006] The purpose of this invention is to provide an improved turning conveyor device to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: an improved turning conveyor device, comprising a frame, multiple sets of conical rollers mounted on the frame, and a drive assembly for driving the multiple sets of conical rollers to rotate. One end of each conical roller has a transmission rod, and the multiple sets of conical rollers are arranged sequentially in a fan-shaped structure. A rotating seat is installed at the position corresponding to the transmission rod on the frame. The transmission rod of each conical roller is rotatably mounted on the rotating seat. The other end of each conical roller is suspended in the air. A driven wheel is constructed on the transmission rod, and the drive assembly is connected to the driven wheel to drive the conical rollers to rotate.

[0008] The generatrices of the multiple sets of conical rollers at their upper ends are all in the same plane, thus forming a horizontally continuous conveying surface at the upper ends of the multiple sets of conical rollers.

[0009] The conical rollers are arranged in a fan shape around the same center, and there is a movable gap between adjacent sets of conical rollers.

[0010] The rotating seat is a first bearing seat, which is mounted on the frame, and the transmission rod of the tapered roller is rotatably mounted on the first bearing seat.

[0011] The frame is also equipped with a support rotating base for supporting and assisting the rotation of the conical roller, and the transmission rod is rotatably mounted on the support rotating base.

[0012] The supporting pivot is a second bearing housing, and the axis of the bearing inner hole on the first bearing housing, the axis of the bearing inner hole on the second bearing housing, and the axis of the transmission rod are all distributed on the same straight line.

[0013] The second bearing housing is located between the first bearing housing and the tapered roller. The height of the inner bore of the second bearing housing is greater than the height of the inner bore of the first bearing housing, causing the tapered roller assembled on the first and second bearing housings to tilt upward.

[0014] The drive assembly includes a drive motor and multiple transmission chains, each transmission chain meshing with a driven wheel on a transmission rod, and the output end of the drive motor meshing with one of its transmission chains.

[0015] A protective cover is constructed on the frame, and the first bearing housing, the second bearing housing, and the transmission rod are all placed inside the protective cover.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows: This application sets multiple sets of conical rollers on the frame, which are arranged in a fan-shaped structure. The upper ends of the multiple sets of conical rollers form a continuous conveying surface. The transmission rod on the outer side of the conical roller is rotatably mounted on the first bearing seat and the second bearing seat. It can both drive the conical roller to rotate and support the entire conical roller. The other end of the conical roller is suspended. Since the upper ends of the multiple sets of conical rollers form a continuous conveying surface, the material can be directly placed on the roller for conveying without the need for a belt. This solves the problem of the belt slipping on the roller due to the excessive weight of the material, which prevents the material from being conveyed smoothly. This turning conveyor device is suitable for production lines that convey materials with larger weights, further improving the stability and continuity of material conveying.

[0017] Furthermore, since this turning conveyor does not require belt conveying, and the outer end of the conical roller has two sets of bearing seats to support the entire conical roller, the inner end of the conical roller can be suspended, which makes the inner diameter of the turning conveyor smaller and suitable for production lines with two sets of straight conveyor belts arranged compactly.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Example 1: As Figure 1-5As shown, an improved turning conveyor includes a frame 1, multiple sets of conical rollers 11 mounted on the frame 1, and a drive assembly for driving the multiple sets of conical rollers 11 to rotate. Each conical roller 11 has a transmission rod 12 at its outward-facing end. The multiple sets of conical rollers 11 are arranged in a fan-shaped structure. A rotating seat is installed on the frame 1 at a position corresponding to the transmission rod 12. The transmission rod 12 of each conical roller 11 is rotatably mounted on the rotating seat. The rotating seat can both drive the conical roller 11 to rotate and support the entire conical roller 11. The other end of each conical roller 11 is suspended in the air. A driven wheel 14 is constructed on the transmission rod 12, and the drive assembly is connected to the driven wheel 14. Specifically, when the drive assembly is started... The drive assembly drives the driven wheel 14 to rotate, and multiple sets of conical rollers 11 rotate synchronously around the rotating base. The material is transported forward along the direction of the conical rollers 11 by the friction between the material and the conical rollers 11, realizing the turning and conveying of the material. Furthermore, since the generatrices of the multiple sets of conical rollers are all in the same plane, the upper ends of the multiple sets of conical rollers form a horizontal and continuous conveying surface. The material can be placed directly on the rollers for conveying without the need for a belt. This solves the problem of the belt slipping on the rollers due to the heavy material, which prevents the material from being conveyed smoothly. This makes the turning conveyor suitable for production lines that convey materials with larger masses, further improving the stability and continuity of material conveying.

[0027] The transmission rod 12 extends outward from the end of the conical roller 11 with the larger outer diameter, and the axis of the transmission rod 12 coincides with the axis of the conical roller 11, ensuring that the transmission rod 12 and the conical roller 11 rotate around the same axis.

[0028] Specifically, multiple sets of conical rollers 11 are arranged in a fan shape around the same center at equal angles. There is a movable gap between adjacent sets of conical rollers 11. There is also a movable space between the bottom of the multiple sets of conical rollers 11 and the upper surface of the frame 1. The outer ends of the multiple sets of conical rollers are all distributed on the same outer arc line, and their inner ends are also distributed on the same inner arc line. The diameter of the outer arc line is larger than the diameter of the inner arc line, which realizes the turning of the conveyor belt. The linear velocity of the material on the conveying surface is proportional to the straight distance from the center of the circle to the material, so that the material can move within the conveying surface without deviating from the conveying surface.

[0029] On an actual production line, the length and turning angle of the turning machine can be adjusted by changing the number of conical rollers according to the conveying requirements.

[0030] In this embodiment, the rotating seat is a first bearing seat 13, which is mounted on the frame 1. The transmission rod 12 of the conical roller 11 is rotatably mounted on the first bearing seat 13. A support rotating seat for supporting and assisting the rotation of the conical roller 11 is also constructed on the frame 1. The transmission rod 12 is rotatably mounted on the support rotating seat. The support rotating seat is a second bearing seat 15. The first bearing seat and the second bearing seat can both drive the conical roller to rotate and support the entire conical roller. Furthermore, since the inward end of the conical roller on this turning conveyor can be suspended, the inner diameter of the turning conveyor is relatively small, making it suitable for compactly arranged production lines.

[0031] Specifically, the support swivel is a second bearing seat. The axis of the bearing inner hole on the first bearing seat 13, the axis of the bearing inner hole on the second bearing seat 15, and the axis of the transmission rod 12 are all distributed on the same straight line, ensuring that the first bearing seat, the second bearing seat, and the transmission rod rotate coaxially.

[0032] In this embodiment, the second bearing housing 15 is located between the first bearing housing 13 and the tapered roller 11. The first bearing housing and the second bearing housing are spherical bearings with mounting brackets. A heightening block is installed at the bottom of the second bearing housing 15 so that the height of the inner hole of the bearing in the second bearing housing 15 is greater than the height of the inner hole of the bearing in the first bearing housing 13. Combining the characteristic that the axis of the spherical bearing with mounting bracket can swing, the tapered roller 11 mounted on the first bearing housing 13 and the second bearing housing 15 is tilted upward, so that multiple sets of tapered rollers form a horizontal conveying surface.

[0033] The bearings on the first bearing housing 13 and the second bearing housing 15 are all inclined upward relative to the horizontal surface from the end away from the tapered roller 11 toward the tapered roller.

[0034] In this embodiment, the drive assembly includes a drive motor 17 mounted on a frame and multiple transmission chains 18. Each transmission chain 18 meshes with a driven wheel 14 on a transmission rod 12. The output end of the drive motor 17 meshes with one of its transmission chains 18. Specifically, the driven wheel is a double-layer sprocket, which is sleeved on the transmission rod. From the outer layer transmission structure, except for the first and last transmission rods, adjacent transmission rods form a transmission unit (transmission rod one and transmission rod two) starting from the beginning of the turning conveyor. The outer sprockets on transmission rod one and transmission rod two are connected by a set of chain links. From the inner layer transmission structure, including the first and last transmission rods, adjacent transmission rods form a transmission unit starting from the beginning of the turning conveyor. The inner sprockets on the two transmission rods are connected by a set of chain links. The outer sprocket at one end of the transmission rod meshes with one end of a transmission chain, and the other end of the transmission chain meshes with the output end of the drive motor.

[0035] Preferably, the first bearing seat 13 and the second bearing seat 15 are spaced apart, and the double-layer sprocket and the transmission chain 18 are placed between the first bearing seat 13 and the second bearing seat 15, making the structure of the turning conveyor belt more compact and reducing the space occupied.

[0036] Preferably, a protective cover 16 is constructed on the frame 1, and the first bearing seat 13, the second bearing seat 15, the transmission rod 12 are all placed inside the protective cover 16. The bottom of the protective cover 16 facing the conical roller 11 is provided with a clearance space to avoid interfering with the rotation of the transmission rod 12. The protective cover can protect the components of the conical roller transmission part.

[0037] The conical roller is made of metal, which enhances its load-bearing capacity.

[0038] The working principle of this turning conveyor is as follows: the drive motor drives the transmission rod to rotate on the first and second bearing seats through the drive transmission chain, which in turn drives the conical drum to rotate synchronously. The upper ends of multiple sets of conical drums form a horizontal and continuous conveying surface. This conveying surface has a fan-shaped structure, and the material can be directly placed on the drum for turning and conveying.

[0039] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
