Detailed Implementation

[0026] The present patent can be further understood through the specific embodiments given below, but they are not intended to limit the present patent.

[0027] Example 1: A heavy-duty profile conveying mechanism, comprising: a base support 1, at least two support beams 2 each mounted on the base support 1 and extending in the front-rear direction, at least two conveyor belts 3 corresponding to the support beams 2, and a drive unit 4. The support beams 2 are arranged parallel to each other in the left-right direction at intervals. Each support beam 2 has a driven sprocket 5 rotatably mounted at both ends and a driving sprocket 6 rotatably mounted at its middle. Each driven sprocket 5 and driving sprocket 6 includes: a spindle 71, sleeved on... The sprocket portion 72 on the spindle 71 and the pulley portion 73 sleeved on the spindle 71 and located on both sides of the sprocket portion 72, the outer diameter of the pulley portion 73 is larger than the outer diameter of the sprocket portion 72, the pulley portion 73 of the driven belt sprocket 5 and the driving belt sprocket 6 mounted on the same support beam 2 are connected by the transmission belt 3, and the sprocket portion 72 of the driven belt sprocket 5 and the driving belt sprocket 6 mounted on the same support beam 2 are connected by a chain 8, so that the chain 8 is located inside the transmission belt 3 that moves synchronously with it;

[0028] The drive sprocket 6 is rotatably mounted between two first support side plates 91 via two bearing seats 10. The upper ends of the two first support side plates 91, which are respectively located on both sides of the support beam 2, are connected to the support beam 2. A tensioning pulley 11 is respectively arranged between the two first support side plates 91 and on the front and rear sides of the drive sprocket 6. A tensioning sprocket 17 is arranged between the two tensioning pulleys 11. The tensioning pulley 11 and the pulley portion 73 of the drive sprocket 6 are in transmission contact with the two side surfaces of the conveyor belt 3, respectively. The tensioning sprocket 17 and the sprocket portion 72 of the drive sprocket 6 are in transmission cooperation with the two sides of the chain 8, respectively.

[0029] Each of the aforementioned tension pulley 11 and tension sprocket 17 is rotatably mounted on a support shaft 18 via at least two bearings. The two ends of the support shaft 18 of the tension sprocket 17 and the support shaft 18 of at least one tension pulley 11 pass through slotted holes 12 formed in the first support side plate 91. The inner walls of the front-to-back extending slotted holes 12 are slidably fitted with the support shaft 18. Each of the two first support side plates 91, opposite to the outer sides of the tension pulley 11 and tension sprocket 17, is provided with a front-to-back extending slot. The pull rod 13 has one end connected to the support shaft 18 of the tension pulley 11 or tension sprocket 17, and the other end of each pull rod 13 extends towards the conveyor belt 3 or chain 8 and is fitted with a blocking ring 14. Each of the two first support side plates 91 is provided with a blocking block 15 on the side wall of the tension pulley 11 and tension sprocket 17, which allows the pull rod 13 to pass through. The two ends of an elastic member 21 fitted on the pull rod 13 are respectively pressed into contact with the blocking ring 14 and the blocking block 15.

[0030] The retaining ring on the pull rod is squeezed by the elastic element, causing the pull rod to always tend to move towards the drive wheel. This, in turn, causes the tension pulley or tension sprocket to always move closer to the corresponding conveyor belt or chain, keeping the conveyor belt or chain between it and the pulley or sprocket of the drive wheel taut. This ensures a large-area close fit between the drive belt and the pulley of the drive wheel, and a tight fit between the chain and the sprocket of the drive wheel, preventing tooth slippage. This maintains good transmission contact, avoids transmission failure caused by conveyor belt slippage or chain tooth slippage, and improves the stability and efficiency of the conveyor.

[0031] Each of the aforementioned support beams 2 is mounted on the base bracket 1 by at least two supports 19 spaced apart along its length; each of the aforementioned supports 19 and located below the conveyor belt 3 is rotatably mounted with a guide wheel 191 that rolls in contact with the lower surface of the conveyor belt 3.

[0033] The spindle 71 of the drive belt sprocket 6 located between the two first support side plates 91 is rotatably mounted on the adjacent first support side plate 91 at both ends via a bearing seat 10.

[0034] The aforementioned blocking block 15 is integrally formed on the first support side plate 91; the aforementioned elastic element 21 is a spring extending back and forth, and the aforementioned blocking ring 14 is a nut threadedly connected to the pull rod 13.

The spindle 71 of each of the aforementioned drive sprockets 6 is fitted on the outside of the synchronous shaft 43 and in a transmission cooperation with the synchronous shaft 43.

[0036] Example 2: A heavy-duty profile conveying mechanism, comprising: a base support 1, at least two support beams 2 each mounted on the base support 1 and extending in the front-rear direction, at least two conveyor belts 3 corresponding to the support beams 2, and a drive unit 4. The support beams 2 are arranged parallel to each other in the left-right direction at intervals. Each support beam 2 has a driven sprocket 5 rotatably mounted at both ends and a driving sprocket 6 rotatably mounted at its middle. Each driven sprocket 5 and driving sprocket 6 includes: a spindle 71, sleeved on... The sprocket portion 72 on the spindle 71 and the pulley portion 73 sleeved on the spindle 71 and located on both sides of the sprocket portion 72, the outer diameter of the pulley portion 73 is larger than the outer diameter of the sprocket portion 72, the pulley portion 73 of the driven belt sprocket 5 and the driving belt sprocket 6 mounted on the same support beam 2 are connected by the transmission belt 3, and the sprocket portion 72 of the driven belt sprocket 5 and the driving belt sprocket 6 mounted on the same support beam 2 are connected by a chain 8, so that the chain 8 is located inside the transmission belt 3 that moves synchronously with it;

[0037] The drive sprocket 6 is rotatably mounted between two first support side plates 91 via two bearing seats 10. The upper ends of the two first support side plates 91, which are respectively located on both sides of the support beam 2, are connected to the support beam 2. A tensioning pulley 11 is respectively arranged between the two first support side plates 91 and on the front and rear sides of the drive sprocket 6. A tensioning sprocket 17 is arranged between the two tensioning pulleys 11. The tensioning pulley 11 and the pulley portion 73 of the drive sprocket 6 are in transmission contact with the two side surfaces of the conveyor belt 3, and the tensioning sprocket 17 and the sprocket portion 72 of the drive sprocket 6 are in transmission cooperation with the two sides of the chain 8.

[0038] In use, several heavy workpieces are placed on the conveyor belt in sequence, so that the lower surface of the workpieces overlaps with each conveyor belt.

[0039] The drive unit drives each active belt sprocket to rotate synchronously, thereby synchronously driving the driven belt sprocket to rotate under the combined action of the chain and the conveyor belt. The chain and the conveyor belt move synchronously. The chain mainly plays the role of transmission and support, while the conveyor belt contacts the workpiece. The workpiece is transferred without damaging it, avoiding the situation where the conveyor belt slips or the transmission fails due to the excessive weight of the workpiece.

[0040] Each of the aforementioned support beams 2 is mounted on the base bracket 1 by at least two supports 19 spaced apart along its length.

[0041] Each of the aforementioned supports 19 is rotatably mounted on and below the conveyor belt 3, and a guide wheel 191 is in rolling contact with the lower surface of the conveyor belt 3.

[0042] The spindle 71 of the drive belt sprocket 6 located between the two first support side plates 91 is rotatably mounted on the adjacent first support side plate 91 at both ends via a bearing seat 10.

[0043] The aforementioned drive unit 4 includes a motor 41 mounted on the base bracket 1, a reducer 42 connected to the output shaft of the motor 41, and a synchronous shaft 43 connected to the reducer 42 in a transmission manner. The spindle 71 of each of the aforementioned drive sprockets 6 is fitted on the outside of the synchronous shaft 43 and in a transmission cooperation with the synchronous shaft 43.

[0044] The aforementioned synchronous shaft 43 is a hexagonal shaft; the outer diameter of the aforementioned driving sprocket 6 is larger than the outer diameter of the driven sprocket 5.

[0045] The six support beams 2 are arranged at equal intervals in the left-right direction; each of the driven belt sprockets 5 is rotatably mounted on the outer side of one end of the support beam 2 via two second support side plates 92.

[0046] The working principle of this utility model is as follows:

[0047] In use, several heavy workpieces are placed on the conveyor belt in sequence, so that the lower surface of the workpieces overlaps with each conveyor belt.

[0048] The drive unit drives each active belt sprocket to rotate synchronously, thereby driving the driven belt sprocket to rotate synchronously under the combined action of the chain and the conveyor belt. The chain and the conveyor belt move synchronously. The chain mainly plays the role of transmission and support, while the conveyor belt contacts the workpiece. The workpiece is transferred without damaging it, avoiding the situation where the conveyor belt slips or the transmission fails due to the excessive weight of the workpiece.

[0049] The connections between the various components in the drive unit and between each component and the drive belt sprocket all adopt common connection methods in the existing technology (such as keyway mating, etc.), which will not be elaborated here;

[0050] During the above process, the retaining ring on the pull rod is squeezed by the elastic element, which always causes the pull rod to tend to move towards the drive wheel. This causes the tension pulley or tension sprocket to always tend to move closer to the corresponding conveyor belt or chain, so as to keep the conveyor belt or chain between it and the pulley part or sprocket part of the drive pulley in a taut state. This ensures a large area of ​​tight contact between the transmission belt and the pulley part of the drive wheel, and a tight fit between the chain and the sprocket part of the drive wheel to prevent tooth derailment. This maintains good transmission contact and avoids transmission failure caused by conveyor belt slippage or chain tooth derailment, thereby improving the stability and efficiency of the conveyor.

[0051] When using the above-mentioned heavy-duty profile conveying mechanism, while conveying heavy workpieces, it can protect the workpiece surface from damage and ensure the stability of the conveying. It can also prevent the conveyor belt from slipping and the transmission from failing due to the excessive weight of the workpiece. Furthermore, it can always maintain the tension of the conveyor belt and chain between the tension pulley, tension sprocket and the pulley and sprocket of the drive sprocket, so that the conveyor belt, chain and the pulley and sprocket of the drive sprocket can always maintain good transmission cooperation, avoid transmission failure caused by slippage or tooth derailment, and improve the stability and efficiency of the conveying.

[0052] The above embodiments are only for illustrating the technical concept and features of this utility model, and are intended to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They should not be construed as limiting the scope of protection of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be included within the scope of protection of this utility model.
