Description

Technical Field

[0001] This utility model relates to the field of conveyor technology, and in particular to a ring conveyor for heavy-duty material transport. Background Technology

[0002] In industrial production, circular conveyor lines are widely used for material transport due to their space-saving design. However, existing circular conveyor lines are mostly suitable for transporting lightweight materials (weighing less than 300 kg).

[0003] In existing technologies, circular conveyor lines typically move materials by placing drive sprockets at two circular positions on the conveyor line and mounting a chain around them. The drive sprockets then drive the chain to move, achieving material movement. However, for heavy-duty materials (weighing more than 1.5 tons), this driving method places extremely high demands on the structural strength and wear resistance of the chain. Furthermore, the inertia generated when heavy-duty materials reach the circular positions often causes gaps in the meshing between the chain and sprockets, resulting in slow operating speeds and hindering production acceleration. Therefore, traditional circular conveyor lines often suffer from unstable operation, susceptibility to damage, and high maintenance costs when transporting heavy materials. These problems not only severely impact production efficiency but also significantly increase operating costs for enterprises. Summary of the Invention

[0004] To overcome the above-mentioned defects, this utility model provides a heavy-duty circular conveyor line with a simple structural design that ensures stable and reliable meshing between gears and racks, thereby effectively increasing the production speed to 1m / s and providing rapid conveying speed to meet the needs of heavy-duty material transportation.

[0043] The preferred embodiment of the present invention will be described in detail below with reference to the accompanying drawings.

[0044] See Figures 1 to 6 This utility model provides a heavy-duty circular conveyor line, including a circular line body 1. The circular line body is the existing elliptical conveyor line, therefore the entire line body is not shown in the drawings. Figure 1 and 2 The structure of a portion of the circular arc segment and a portion of the straight line segment of the toroidal body is shown for reference.

[0045] In this embodiment, the annular line 1 is configured as an annular line composed of two parallel and spaced-apart guide plates 11. For ease of description, the two guide plates 11 are defined as the inner guide plate 111 and the outer guide plate 112, respectively. The inner guide plate 111 and the outer guide plate 112 are coaxially arranged, and the semi-axial length of the inner guide plate 111 is less than the semi-axial length of the outer guide plate 112, meaning the inner guide plate 111 is located within the ring of the outer guide plate 112. A toothed plate 12, coaxial with the inner guide plate 111 and the outer guide plate 112, is provided between them. The toothed plate 12 is positioned close to the inner guide plate 111, and its teeth face the outer guide plate 112. It is understood that the inner guide plate 111, the toothed plate 12, and the outer guide plate 112 are arranged sequentially from the inside out.

[0046] Multiple pallets 2 for carrying materials are provided on the circular conveyor 1. The pallets 2 are designed to move on the circular conveyor 1 with the materials on them. Each pallet 2 is equipped with a limit sensor 7, which is located at the rear end of the pallet 2 via a connecting plate 71, controlling the distance between adjacent pallets 2 on the circular conveyor 1 according to the direction of pallet movement. To achieve pallet movement, this embodiment provides a drive mechanism 3 on each pallet. The drive mechanism 3 includes a motor 31 and a drive gear 32 connected to the output shaft of the motor 31. The drive gear 32 meshes with a toothed plate 12, so when the motor 31 drives the drive gear 32 to rotate around its axis, it moves along the path of the toothed plate 12, thereby moving the pallet. The drive of each pallet 2 is independently configured, providing the necessary power for pallets carrying heavy materials, facilitating the transport of heavy materials.

[0047] Meanwhile, to ensure stable and rapid movement of the pallet on the circular conveyor belt 1 when transporting heavy materials, this embodiment provides a steering mechanism 4 at the bottom of the pallet 2. This steering mechanism 4 is movably positioned at the bottom of the pallet 2 and includes two sets of pulley assemblies 41. The two sets of pulley assemblies 41 are respectively configured to be rolledly connected to two guide plates 11, tangential to the inner and outer sides of the circular conveyor belt. The two sets of pulley assemblies 41 not only help ensure stable meshing between the drive gear and the toothed plate, but also allow the pallet to smoothly transition from the straight section to the arc section of the circular conveyor belt without slowing down. By providing a steering mechanism at the bottom of the pallet, the pallet's running speed can reach 1 m / s.

[0048] Furthermore, two sets of steering mechanisms 4 can be configured along the moving direction of pallet 2 on the annular conveyor belt 1. These two sets of steering mechanisms 4 are respectively positioned at the front and rear ends of the bottom of pallet 2 along the moving direction of pallet 2. A tray 6 for positioning materials is provided at the top front end of pallet 2, and the steering mechanism 4 at the front end is positioned directly below the tray 6, meaning the center of the steering mechanism coincides with the center of the tray. The steering mechanism 4 at the rear end is equipped with a drive mechanism 3. The arrangement of the two sets of steering mechanisms helps to balance the front and rear positions of the pallet, and by arranging the motor and tray in a front-rear configuration, the center of gravity of the pallet is centered. (See reference...) Figure 1 To ensure the overall stability of the pallet, a counterweight frame 8 can be installed on the pallet according to the weight of the material it carries. The counterweight frame is configured to be position-variable so as to adjust the center of gravity of the pallet when it carries different weights of material.

[0049] Furthermore, the steering mechanism 4 also includes a steering plate 42 arranged parallel to the support plate 2. The steering plate 42 is connected to the bottom of the support plate 2 via a bearing 43. Two sets of pulley assemblies 41 are symmetrically arranged at both ends of the steering plate 42, that is, the two sets of pulley assemblies are radially symmetrical about the axis of the bearing. The bearing 43 has an inner ring and an outer ring arranged coaxially. The support plate 2 is positioned and connected to the outer ring of the bearing 43; the steering plate 42 is positioned and connected to the inner ring of the bearing 43, so that the steering plate 42 can swing around the axis of the bearing 43 when subjected to force. When the support plate 2 moves in the arc segment of the annular line 1, the steering plate can change its angle according to the change of the track under the drive of the pulley assembly 41 (see...). Figure 3 (as shown), to ensure that the meshing of the drive gear and the toothed plate remains stable.

[0050] Furthermore, each pulley assembly 41 includes two first rollers 411 and one second roller 412. The two first rollers 411 are respectively disposed on the upper and lower sides of the corresponding end guide plate 11, and the axial directions of the two first rollers 411 are parallel to the guide plate 11, and they are in rolling connection with the upper and lower sides of the guide plate 11. The second roller 412 is disposed on the outer side of the corresponding end guide plate 11, and the axial direction of the second roller 412 is perpendicular to the guide plate 11, and it is in rolling connection with the outer side of the guide plate 11. Taking the pulley assembly on one side of the inner guide plate 111 as an example, the two first rollers 411 and the second roller 412 form a "]" shaped structure, which restricts the upper and lower sides and the outer side of the inner guide plate 111 within the groove of the structure, thereby ensuring the limiting between the pulley assembly and the inner guide plate 111, and further ensuring the stable meshing of the drive gear and the toothed plate during the movement of the pallet on the entire annular line.

[0051] Furthermore, the support plate 2 and the steering plate 42 are respectively provided with a first through hole 21 and a second through hole 421 arranged coaxially with the bearing 43; the output shaft of the motor 31 is coaxially arranged with the bearing 43, and passes through the first through hole 21, the inner ring of the bearing 43 and the second through hole 421 in the vertical direction before connecting to the drive gear 32. This ensures that the axes of the motor output shaft, the drive gear, and the bearing are on the same center line, and in conjunction with the steering mechanism, keeps the drive gear meshing with the gear plate, avoiding tooth disengagement during rapid movement.

[0052] The drive mechanism 3 also includes a driven gear 33, which is located at the bottom of the steering plate 42 and meshes with the drive gear 32. The driven gear 33 is also located on the side close to the outer guide plate 112. That is, the driven gear and the gear plate are located at the two ends of the drive gear in the radial direction, which further ensures the meshing of the drive gear and the gear plate.

[0053] Furthermore, to ensure good meshing between the drive gear and the gear plate during installation, the meshing clearance between the drive gear and the gear plate needs to be adjusted during motor installation. In this embodiment, the motor 31 is positioned on the support plate 2 via the mounting plate 34. Simultaneously, the mounting plate 34 can make slight positional movements along the inward and outward directions on the support plate 2, through the oblong holes (e.g., ...) on the mounting plate. Figure 6 (As shown) This is achieved. The fine-tuning of the position is achieved by the adjustment mechanism 5 set on the support plate 2. The adjustment mechanism is set near the outer side of the ring line body to generate an inward elastic thrust on the mounting plate. A limiting block 35 is set on the side of the mounting plate 34 facing the adjustment mechanism 5 to increase the contact surface with the adjustment mechanism.

[0054] Specifically, the adjustment mechanism includes a positioning block 51 configured to be located on the top of the support plate 2 and facing the outer guide plate 112; and a screw 52 arranged horizontally and threaded to the positioning block 51 at its outer end. The rear end of the screw is a hexagonal stud, which facilitates tool clamping and rotation of the screw. A pressure plate 53 is provided on one side of the inner end of the screw 52, ​​which is configured to elastically press against the drive mechanism 3. Simultaneously, a limit plate 54, a limit nut 55, and a return spring 56 are also provided on the screw 52. The limit plate 54 is located between the positioning block 51 and the pressure plate 53, the limit nut 55 is located between the positioning block 51 and the limit plate 54, and the return spring 56 is located between the pressure plate 53 and the limit plate 54. The pressure plate 53 is connected to the inner end of the return spring, thereby allowing the pressure plate to move elastically along the axis of the screw. The limit nut 55 is threaded to the screw and can move on the screw to change the position of the limit plate. An adjustment mechanism is provided to adjust the meshing clearance between the drive gear and the toothed plate during motor installation. Furthermore, the elastic thrust generated by the adjustment mechanism causes the pallet to move along the arc section, creating an inward floating thrust on the drive mechanism. This eliminates outward inertia caused by excessive speed, ensuring good meshing between the drive gear and the toothed plate in the arc section, and further guaranteeing the stability of the pallet during high-speed movement on the circular conveyor belt.

[0055] In summary, the heavy-duty circular conveyor line provided by this utility model adopts a simple structural design to ensure stable and reliable meshing between gears and racks, thereby effectively increasing the production speed to 1m / s. The conveying speed is fast and stable to meet the needs of heavy-duty material transportation.
