[0002] In the packaging industry, conveyors are used to transport products to be packaged or to transport the boxes that contain them. Dual-servo conveyors feature two synchronous belts, each driven by a corresponding servo motor, which improves conveyor efficiency. Each synchronous belt is secured with a set of belt attachments to accommodate the boxes or products being conveyed. Current dual-servo conveyors lack auxiliary positioning, resulting in high motion resistance and slow conveyor line speeds, making them difficult to adapt to high-speed conveying. Furthermore, the addition of these belt attachments reduces the rigidity of the belt structure, leading to poor belt accuracy and difficulty accommodating heavier boxes or products. Utility Model Content

[0010] Alternatively, a plurality of fixed support rods are provided on the outer side surface of the left guide plate, and a plurality of adjustable support rods are provided on the outer side surface of the right guide plate, and the adjustable support rods and the fixed support rods are respectively connected to the vertical rods on the frame.

[0025] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention and are not used to limit the present invention.

[0026] like Figure 1 、 2 As shown, a high-speed dual-servo conveyor includes a frame on which two synchronous belts driven by two servo reducer combinations are arranged. Among the two servo reducer combinations, the first servo reducer combination 1 is used to drive the first synchronous belt 6 to rotate, and the second servo reducer combination 2 is used to drive the second synchronous belt 5 to rotate.

[0027] The first and second synchronous belts 6 and 5 are each provided with a synchronous belt accessory assembly, which is used for product conveying and positioning. In this embodiment, the installation of the synchronous belt accessory assembly on the first synchronous belt 6 is used as an example to illustrate the installation method of the synchronous belt accessory assembly. The synchronous belt accessory assembly on the second synchronous belt 5 adopts the same installation method and will not be further described.

[0028] like Figure 1 、 2 3. The first synchronous belt is provided with two groups of synchronous belt accessory groups, namely, synchronous belt accessory group A 7 and synchronous belt accessory group B 8. The two groups are arranged at intervals, and both groups of synchronous belt accessory groups include multiple synchronous belt accessory units. In this embodiment, each synchronous belt accessory group has 10 synchronous belt accessory units. Each synchronous belt accessory unit includes a fixed plate 13 and a baffle 14. The dimension of the fixed plate 13 perpendicular to the conveying direction is greater than the sum of the widths of the first synchronous belt 6 and the second synchronous belt 5, so that both ends of the fixed plate 13 can extend out of the first synchronous belt 6 and the second synchronous belt 5. One end of the fixed plate 13 is clamped on the first synchronous belt 6, and the other end of the fixed plate 13 is provided with an avoidance groove at a position opposite to the second synchronous belt 5 to avoid contact with the second synchronous belt 5. The baffle 14 is provided on the fixed plate 13 and corresponds to the position of the first synchronous belt 6. Adjacent baffles 14 form a conveying position for placing products. In this embodiment, 10 synchronous belt accessory units form 10 conveying positions.

[0029] For example Figure 4 、 5 As shown, pulleys 15 are respectively provided at both ends of the fixed plate 13. Specifically, two pulleys 15 are provided at each end. When the first synchronous belt 6 rotates, the pulleys 15 slide along the slide grooves 16 on the outside of the first synchronous belt 6 and the second synchronous belt 5, which can provide better support for the first synchronous belt 6, reduce the conveying resistance, and further increase the conveying speed.

[0030] Continue to refer Figure 1 、 2 As shown, in order to ensure that the product can smoothly enter the conveying position on the synchronous belt attachment, a feed guide frame 10 is also provided at the feed port of the conveyor, and the feed channel of the feed guide frame 10 is aligned with the first synchronous belt 6.

[0031] Furthermore, the feed guide frame 10 includes a left guide plate 1001 and a right guide plate 1002. The left guide plate 1001 is provided with a plurality of adjustment support rods 1003, and the adjustment support rods 1003 are provided with length scales. The right guide plate 1002 is provided with a plurality of fixed support rods 1006. The adjustment support rods 1003 and the fixed support rods 1006 are respectively fixedly connected to the vertical poles 1005 by clamping blocks 1004 and bolts, and the vertical poles are fixed to the frame. When the width of different batches of products is different, it is necessary to adjust the width of the feed channel of the feed guide frame 10. At this time, the clamping block 1004 between the adjustment support rod 1003 and the vertical pole 1005 can be loosened, and the adjustment support rod can be slid according to the width of the product to adjust the position of the left guide plate 1001. After the adjustment is in place, the loosened clamping block 1004 can be re-clamped to fix the adjustment support rod 1003.

[0032] It can be understood that the arrangement positions of the adjustable support rod 1003 and the fixed support rod 1006 can be interchanged without affecting the formation of the feed guide frame.

[0033] It should be noted that the conveyor of the present invention uses a synchronous belt for conveying each time it is used. At this time, the synchronous belt accessory group needs to be fixed on the synchronous belt to be used, and the position of the feed guide frame 10 needs to be adjusted to align with the synchronous belt to be used.

[0034] In order to realize the separate driving of the two synchronous belts, the transmission mechanism adopted by the present invention is as follows Figure 6 、 7As shown, a drive shaft is provided at each end of the conveyor frame, with a first drive shaft 17 in driving connection with the first servo reducer assembly 1, and a second drive shaft 18 in driving connection with the second servo reducer assembly 2. A first synchronous pulley 4 and a first idler pulley 3 are provided on the first drive shaft 17. The first synchronous pulley 4 is fixedly connected to the first drive shaft 17, so that the first synchronous pulley 4 and the first drive shaft 17 can rotate synchronously. The first idler pulley 3 is mounted on the first drive shaft 17 via a bearing, so that the first idler pulley 3 does not rotate with the first drive shaft 17. A second synchronous pulley 11 and a second idler pulley 12 are provided on the second drive shaft 18. The second synchronous pulley 11 is fixedly connected to the second drive shaft 18, so that the second synchronous pulley 11 and the second drive shaft 18 can rotate synchronously. The second idler pulley 12 is mounted on the second drive shaft 18 via a bearing, so that the second idler pulley 12 does not rotate with the second drive shaft 18. The two ends of the first synchronous belt 6 are respectively meshed and connected to the first synchronous pulley 4 and the second idler pulley 12, and the two ends of the second synchronous belt 5 are respectively meshed and connected to the second synchronous pulley 11 and the first idler pulley 3, so that the first servo reducer assembly 1 drives the first synchronous belt 6 to rotate through the transmission of the first transmission shaft 17 and the first synchronous pulley 4, and the second servo reducer assembly 2 drives the second synchronous belt 5 to rotate through the transmission of the second transmission shaft 18 and the second synchronous pulley 11.

[0035] During operation of the present invention, the number of synchronous belt accessory units within each synchronous belt accessory group can be increased or decreased based on actual conditions. For example, in this embodiment, where 10 synchronous belt accessory units are grouped together and two groups are provided, products continuously enter the synchronous belt accessory group A 7 within the feed guide frame via a conveyor belt. The synchronous belt accessory group A 7 is conveyed forward along with the first synchronous belt 6 until all 10 products leave the feed guide frame 10 and enter the discharge position. At this point, the discharge device on the product line pushes the 10 products from the synchronous belt accessory group A 7 out the side, entering the next process. The synchronous belt accessory group A 7 then advances again along with the first synchronous belt 6, repeating the above-described actions in a cycle. During this process, the synchronous belt accessory group A 7 and the synchronous belt accessory group B 8 can alternately achieve rapid product delivery.

[0036] It should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein with equivalents. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention. The terms used in the description of this application are only for describing specific embodiments and are not intended to limit the exemplary embodiments according to this application.
