Description

Technical Field

[0001] This utility model relates to the field of conveying equipment technology, and in particular to a double-speed chain conveying structure. Background Technology

[0002] Double-speed chain conveyors use chains as traction and load-bearing components to transport materials, enabling tooling plates and workpieces to move quickly and smoothly, achieving continuous conveying and positioning assembly of products. They are widely used in automated production lines, assembly lines, and other scenarios.

[0003] After prolonged operation, the chain of the high-speed chain conveyor may gradually loosen due to external factors, causing the chain to become loose and preventing the high-speed chain conveyor from effectively conveying objects. Therefore, the high-speed chain conveyor needs to be stopped for tension restoration. However, conventional tension restoration often involves adjusting the tension bolts to tighten the chain, which requires a long downtime for maintenance, affecting work progress and resulting in low work efficiency.

[0004] Therefore, we provide a double-speed chain conveyor structure. Utility Model Content

[0005] The purpose of this invention is to address the aforementioned technical problems by providing a double-speed chain conveyor structure that can temporarily adjust the tension of the double-speed chain.

[0006] In view of this, the present invention provides a double-speed chain conveyor structure, including a double-speed chain conveyor belt, a baffle is provided on the outside of the double-speed chain conveyor belt, a vertical transmission component is connected to one end of the baffle, a tension wheel is provided on one side of the vertical transmission component, and a belt transmission component is connected to the lower end of the vertical transmission component.

[0007] Preferably, there are two double-speed chain conveyor belts, which are symmetrically distributed. Two baffles are symmetrically arranged on the outside of the two double-speed chain conveyor belts, and the baffles are fixedly connected to the support base of the double-speed chain conveyor belts.

[0008] Preferably, the vertical transmission assembly includes a support cylinder that is fixedly connected to one end surface of the baffle via a fixing block. There are two support cylinders, which are symmetrically distributed. A screw is rotatably connected inside the support cylinder, and a screw cylinder is threadedly connected to the outer surface of the screw.

[0009] Preferably, a support block is fixedly connected to the outer surface of the screw barrel, a connecting rod is installed at the lower end of the support block, and the tensioning wheel is rotatably connected to one end of the connecting rod.

[0010] Preferably, the tensioning wheel has the same outer surface as the sprocket that drives the double-speed chain conveyor belt to rotate, and the tensioning wheel is engaged with the double-speed chain conveyor belt.

[0011] Preferably, the belt drive assembly includes a main pulley connected to the baffle via a fixing block, and a handle is installed on the upper end of the main pulley.

[0012] Preferably, the lower end of the screw extends beyond the lower surface of the support cylinder, and a secondary pulley is installed at the lower end of the support cylinder. The two secondary pulleys located on the same baffle are staggered, and a belt connects the main pulley and the secondary pulleys.

[0013] Compared with the prior art, the present invention provides a double-speed chain conveyor structure, which has the following advantages:

[0014] 1. This utility model uses two tensioning rollers that move downwards simultaneously to restore the tension of a double-speed chain conveyor belt. First, compared to a single tensioning roller, the two tensioning rollers reduce the downward distance of the single tensioning roller. Furthermore, the two tensioning rollers can apply equal tension to both sides of the double-speed chain conveyor belt, ensuring that the chain of the double-speed chain conveyor belt is evenly stressed. Compared to a single tensioning roller, this avoids problems such as chain deviation and twisting, further improving the tension restoration effect of the double-speed chain conveyor belt and achieving the effect of temporarily restoring the tension of the double-speed chain conveyor belt.

[0015] 2. This utility model uses a tensioning wheel with the same appearance as the sprocket, which enables a tighter and smoother meshing between the tensioning wheel and the chain of the double-speed chain conveyor belt. Compared with ordinary rollers, it can reduce the sliding friction between the chain and the tensioning wheel, reduce running resistance and wear, and improve the service life of the double-speed chain conveyor belt and the tensioning wheel.

[0016] The parts of this device not covered herein are the same as or can be implemented using existing technologies. This utility model has a simple structure and is easy to operate. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, 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.

[0024] Example: A double-speed chain conveyor structure, such as Figures 1-4 As shown, it includes a double-speed chain conveyor belt 1, a baffle 2 is provided on the outside of the double-speed chain conveyor belt 1, a vertical transmission component 3 is connected to one end of the baffle 2, a tension wheel 4 is provided on one side of the vertical transmission component 3, and a belt transmission component 5 is connected to the lower end of the vertical transmission component 3.

[0025] There are two double-speed chain conveyor belts 1, which are symmetrically distributed. Two baffles 2 are symmetrically arranged on the outside of the two double-speed chain conveyor belts 1, and the baffles 2 are fixedly connected to the support base of the double-speed chain conveyor belts 1.

[0026] The vertical transmission assembly 3 includes a support cylinder 301 that is fixedly connected to one end surface of the baffle 2 via a fixing block. There are two support cylinders 301, and the two support cylinders 301 are symmetrically distributed. A screw 302 is rotatably connected inside the support cylinder 301, and a screw cylinder 303 is threadedly connected to the outer surface of the screw 302.

[0027] A support block 304 is fixedly connected to the outer surface of the screw barrel 303. A connecting rod is installed at the lower end of the support block 304, and the tension wheel 4 is rotatably connected to one end of the connecting rod.

[0028] The tensioner 4 has the same appearance as the sprocket that drives the double-speed chain conveyor belt 1 to rotate, and the tensioner 4 is engaged with the double-speed chain conveyor belt 1.

[0029] When the chain of the double-speed chain conveyor belt 1 is not loose, the screw barrel 303 is located at the upper end of the screw 302, and the tensioning wheel 4 is not in contact with the double-speed chain conveyor belt 1. When the chain of the double-speed chain conveyor belt 1 becomes loose, the screw 302 is rotated. Based on the meshing connection between the screw 302 and the screw barrel 303, the screw barrel 303 and the support block 304 are driven to move downward. The two tensioning wheels 4 move downward simultaneously with the support block 304. When the tensioning wheels 4 mesh with the chain of the double-speed chain conveyor belt 1, the tensioning wheels 4... Continue pressing down until the chain tension of the double-speed chain conveyor belt 1 returns to its original state, then stop rotating the screw 302. Under the action of the screw 302 and the screw barrel 303, firstly, the position of the tensioning wheel 4 can be precisely adjusted. According to the slack of the chain of the double-speed chain conveyor belt 1, the tension of the chain of the double-speed chain conveyor belt 1 is precisely restored. Secondly, the screw 302 and the screw barrel 303 have strong self-locking properties, fixing the position of the tensioning wheel 4 and preventing the tensioning wheel 4 from moving up and down. To address the issue of misalignment and ensure the stability of the tensioning pulley 4 during operation, two tensioning pulleys 4 are simultaneously lowered to restore the tension of the double-speed chain conveyor belt 1. Firstly, compared to a single tensioning pulley 4, two tensioning pulleys 4 reduce the downward distance of the tensioning pulley 4. Furthermore, two tensioning pulleys 4 can apply equal tension on both sides of the double-speed chain conveyor belt 1, ensuring that the chain of the double-speed chain conveyor belt 1 is evenly stressed. Compared to a single tensioning pulley 4, this avoids problems such as chain misalignment and twisting, further improving the tension restoration effect of the double-speed chain conveyor belt 1 and achieving the effect of temporarily restoring the tension of the double-speed chain conveyor belt 1, ensuring that it does not affect the current work progress. Secondly, using tensioning pulleys 4 with the same appearance as sprockets allows for a tighter and smoother meshing between the tensioning pulley 4 and the chain of the double-speed chain conveyor belt 1. Compared to ordinary rollers, this reduces the sliding friction between the chain and the tensioning pulley 4, reduces running resistance and wear, and can improve the service life of the double-speed chain conveyor belt 1 and the tensioning pulley 4.

[0030] like Figures 1-4 As shown, the belt drive assembly 5 includes a main pulley 501 connected to the baffle 2 via a fixing block, and a handle is installed on the upper end of the main pulley 501.

[0031] The lower end of the screw 302 extends out of the lower surface of the support cylinder 301. The lower end of the support cylinder 301 is equipped with a secondary pulley 502, and the two secondary pulleys 502 located on the same baffle 2 are staggered. A belt 503 connects the main pulley 501 and the secondary pulleys 502.

[0032] When the chain of the double-speed chain conveyor belt 1 becomes loose, the main pulley 501 is rotated by turning the handle. Under the connection of the belt 503, the auxiliary pulley 502 and the screw 302 are rotated. Under the action of the main pulley 501, the auxiliary pulley 502 and the belt 503, the two tensioning pulleys 4 can be moved up and down simultaneously by rotating the main pulley 501. This ensures the synchronicity of the tensioning pulleys 4 during operation and keeps the two tensioning pulleys 4 at the same horizontal plane. This provides a guarantee for the restoration of the chain tension of the double-speed chain conveyor belt 1. At the same time, rotating the main pulley 501 can also move the two tensioning pulleys 4 down, which is easy to operate and convenient for later inspection and maintenance.

[0033] Working principle: When adjusting the position of the tensioning wheel 4, the main pulley 501 is rotated by turning the handle. Under the connection of the belt 503, the auxiliary pulley 502 and the screw 302 are rotated. Based on the meshing connection between the screw 302 and the screw barrel 303, the screw barrel 303 and the support block 304 are moved downward. The two tensioning wheels 4 move downward at the same time as the support block 304. When the tensioning wheel 4 meshes with the chain of the double-speed chain conveyor belt 1, the tensioning wheel 4 is continuously pressed down until the chain tension of the double-speed chain conveyor belt 1 returns to its original state. Then the rotation of the screw 302 is stopped, and the tension of the double-speed chain conveyor belt 1 is restored.

[0034] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
