Detailed Implementation

[0021] The present patent can be further understood through the specific embodiments given below, but they are not intended to limit the present patent.

[0022] Example 1: An automatic profile conveying mechanism includes: 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 parallel to each other and spaced apart in the left-right direction. Each support beam 2 has a driven wheel 5 rotatably mounted at both ends and a driving wheel 6 rotatably mounted in the middle. The driven wheel 5 and the driving wheel 6 mounted on the same support beam 2 are connected by the conveyor belts 3.

[0023] The drive wheel 6 is rotatably mounted between two first support side plates 7 via two bearing seats 10. The upper ends of the two first support side plates 7, which are respectively located on both sides of the support beam 2, are connected to the support beam 2. A tension wheel 11 is respectively arranged between the two first support side plates 7 and on the front and rear sides of the drive wheel 6. The tension wheel 11 and the drive wheel 6 are respectively in transmission contact with the two side surfaces of the conveyor belt 3. At least one of the tension wheel 11 has its spindle 111 with both ends passing through the strip holes 12 opened on the first support side plate 7. The inner wall of the strip holes 12 extending front and rear is in sliding fit with the spindle 111 of the tension wheel 11.

[0024] Each of the two first support side plates 7 is provided with a pull rod 13 extending forward and backward on the outer side of the tension wheel 11. One end of each pull rod 13 is connected to the spindle 111 of the tension wheel 11, and the other end of each pull rod 13 extends towards the drive wheel 6 and is fitted with a blocking ring 14. Each of the two first support side plates 7 is provided with a blocking block 15 on the side wall opposite to the tension wheel 11 for the pull rod 13 to pass through. The two ends of an elastic member 21 fitted on the pull rod 13 are respectively pressed and contacted with the blocking ring 14 and the blocking block 15.

[0025] 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, in turn, causes the tension wheel to always tend to move closer to the drive wheel, so that the conveyor belt between the pull rod and the drive wheel remains taut. This ensures a large area of ​​tight contact between the conveyor belt and the drive wheel, maintaining good transmission contact, avoiding transmission failure due to slippage, and improving the stability and efficiency of the conveyor.

[0026] The aforementioned blocking block 15 is integrally formed on the first support side plate 7; the aforementioned elastic element 21 is a spring extending back and forth; the aforementioned blocking ring 14 is a nut that is threadedly connected to the pull rod 13.

Each of the aforementioned drive wheels 6 is fitted onto the outside of the synchronous shaft 43 and is driven by the synchronous shaft 43. The aforementioned synchronous shaft 43 is a hexagonal shaft.

[0029] Example 2: An automatic profile conveying mechanism includes: 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 parallel to each other and spaced apart in the left-right direction. Each support beam 2 has a driven wheel 5 rotatably mounted at both ends and a driving wheel 6 rotatably mounted in the middle. The driven wheel 5 and the driving wheel 6 mounted on the same support beam 2 are connected by the conveyor belts 3.

[0030] In use, several workpieces are placed on the conveyor belt in sequence, so that the lower surface of the workpieces overlaps with each conveyor belt. The drive unit drives each drive wheel to rotate synchronously, thereby driving the driven wheel to rotate synchronously under the action of the conveyor belt, thus realizing the transfer of workpieces.

[0031] The drive wheel 6 is rotatably mounted between two first support side plates 7 via two bearing seats 10. The upper ends of the two first support side plates 7, which are respectively located on both sides of the support beam 2, are connected to the support beam 2. A tension wheel 11 is respectively arranged between the two first support side plates 7 and on the front and rear sides of the drive wheel 6. The tension wheel 11 and the drive wheel 6 are respectively in transmission contact with the two side surfaces of the conveyor belt 3. At least one of the tension wheel 11 has its spindle 111 with both ends passing through the strip holes 12 opened on the first support side plate 7. The inner wall of the strip holes 12 extending front and rear is in sliding fit with the spindle 111 of the tension wheel 11.

[0032] Each of the two first support side plates 7 is provided with a pull rod 13 extending forward and backward on the outer side of the tension wheel 11. One end of each pull rod 13 is connected to the spindle 111 of the tension wheel 11, and the other end of each pull rod 13 extends towards the drive wheel 6 and is fitted with a blocking ring 14. Each of the two first support side plates 7 is provided with a blocking block 15 on the side wall opposite to the tension wheel 11 for the pull rod 13 to pass through. The two ends of an elastic member 21 fitted on the pull rod 13 are respectively pressed and contacted with the blocking ring 14 and the blocking block 15.

[0033] The aforementioned blocking block 15 is integrally formed on the first support side plate 7; the aforementioned elongated workpieces 100 to be conveyed extend in the left and right direction and each overlaps and contacts the outer surface of each conveyor belt 3.

[0034] 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 that is driven by the reducer 42. Each of the drive wheels 6 is fitted on the outside of the synchronous shaft 43 and is driven by the synchronous shaft 43.

[0035] The outer diameter of the aforementioned driving wheel 6 is larger than the outer diameter of the driven wheel 5; the aforementioned 6 support beams 2 are arranged at equal intervals in the left and right directions.

[0036] Each of the aforementioned driven wheels 5 is rotatably mounted on the outer side of one end of the support beam 2 via two second support side plates 8.

[0037] The working principle of this utility model:

[0038] In use, several workpieces are placed on the conveyor belt in sequence, so that the lower surface of the workpieces overlaps with each conveyor belt. The drive unit drives each drive wheel to rotate synchronously, thereby driving the driven wheel to rotate synchronously under the action of the conveyor belt, realizing the transfer of workpieces. The connection between each component in the drive unit and between each component and the drive belt sprocket adopts the connection method commonly used in the prior art (such as keyway fit, etc.), which will not be elaborated here.

[0039] 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 wheel to always tend to move closer to the drive wheel, so that the conveyor belt between the pull rod and the drive wheel remains taut. This ensures a large area of ​​tight contact between the transmission belt and the drive wheel to maintain good transmission contact, avoid transmission failure due to slippage, and improve the stability and efficiency of the conveyor.

[0040] When using the above-mentioned automatic profile conveying mechanism, in addition to conveying the workpiece, the tension of the conveyor belt between the tension wheel and the drive wheel can be maintained at all times, so that the conveyor belt and the drive wheel always maintain good transmission contact, avoiding transmission failure caused by slippage, and improving the stability and efficiency of conveying.

[0041] 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.
