Description

Technical Field

[0001] This application relates to the technical field of belt conveyors, and more specifically, to a double-row belt synchronous conveyor device. Background Technology

[0002] Conveyor belts are devices used to transport materials. They move based on the principle of friction drive and can be used for horizontal or inclined transport, making them very convenient to use. Depending on different conveying process requirements, they can be used individually, in multiple units, or combined with other conveying equipment to form horizontal or inclined conveying systems, thus meeting the needs of different layout types of production lines.

[0003] Some existing devices (e.g., patent notice number CN206218642U, entitled "Belt Conveyor") include drive and driven rollers supported by a frame, and a belt mounted on the drive and driven rollers. The belt conveyor also includes a support plate mounted on the frame, positioned between the drive and driven rollers and below the upper belt. The support plate guides the belt through an anti-deviation structure. While such belt conveyors can transport products, when transporting larger products, the width of a single belt line is insufficient to fully support the product. This makes them prone to instability during transport, and large products can easily extend beyond the conveyor belt, causing collisions. Utility Model Content

[0009] In some embodiments, the roller tensioning seat has four sets, which are arranged opposite to each other on the support frame. The driven roller has two sets, which are respectively arranged on both sides of the driving roller, and both ends of each set of driven rollers are rotatably arranged in the roller tensioning seat.

[0010] In some embodiments, the double-row belt synchronous conveyor further includes a tensioning structure, which includes two sets of tensioning rollers and two sets of fixed seats.

[0013] In some embodiments, the conveying structure further includes a photoelectric sensor disposed on a belt support plate, which is used to detect whether there are products on the first conveyor belt and the second conveyor belt.

[0014] In some embodiments, the belt support plate has a detection elongated hole located between the first conveyor belt and the second conveyor belt, and the detection port of the photoelectric sensor is aligned with the detection elongated hole.

[0015] The present application provides a double-row belt synchronous conveyor device, comprising a support frame and a conveying structure.

[0027] like Figure 1 and Figure 2As shown, the embodiment relates to a double-row belt synchronous conveyor device, including: a support frame 10 and a conveying structure 20. The conveying structure 20 includes a drive roller 21, a driven roller 22, a first conveyor belt 23, a second conveyor belt 24, a mounting part 25, and a roller tensioning seat 26. The mounting part 25 and the roller tensioning seat 26 are both mounted on the support frame 10. The drive roller 21 is rotatably mounted on the mounting part 25, and the driven roller 22 is rotatably mounted on the roller tensioning seat 26. The first conveyor belt 23 and the second conveyor belt 24 are both connected to the drive roller 21 and the driven roller 22 in a driving connection. The drive roller 21 and the driven roller 22 are both provided with guide grooves 27, and the first conveyor belt 23 and the second conveyor belt 24 are both provided with guide bars, which cooperate with the guide grooves 27.

[0028] The double-row belt synchronous conveyor device using the technical solution of this embodiment includes a support frame 10 and a conveying structure 20. The conveying structure 20 includes a drive roller 21, a driven roller 22, a first conveyor belt 23, a second conveyor belt 24, a mounting part 25, and a roller tensioning seat 26. The mounting part 25 and the roller tensioning seat 26 are both mounted on the support frame 10. The drive roller 21 is rotatably mounted on the mounting part 25, and the driven roller 22 is rotatably mounted on the roller tensioning seat 26. The first conveyor belt 23 and the second conveyor belt 24 are both connected to the drive roller 21 and the driven roller 22, thereby realizing the conveying function of the first conveyor belt 23 and the second conveyor belt 24 on the products. The drive roller 21 and the driven roller 22 are both provided with guide grooves 27, and the first conveyor belt 23 and the second conveyor belt 24 are both provided with guide bars. The guide bars and the guide grooves 27 cooperate with each other. This arrangement ensures that the positions of the first conveyor belt 23 and the second conveyor belt 24 do not deviate. Furthermore, since the first conveyor belt 23 and the second conveyor belt 24 are sequentially mounted on the same driving roller 21 and driven roller 22, they can jointly convey large-sized products, improving conveying stability. The technical solution of this embodiment effectively solves the problem of the inability to stably convey large-sized products in the prior art.

[0029] It should be noted that both the driving roller 21 and the driven roller 22 are provided with four sets of guide grooves 27, and the first conveyor belt 23 and the second conveyor belt 24 are each provided with two sets of guide bars. The four sets of guide bars and the four sets of guide grooves 27 are arranged in a one-to-one correspondence. Specifically, the guide bars are inserted into the guide grooves 27 so that the movement of the first conveyor belt 23 and the second conveyor belt 24 is not affected, while the first conveyor belt 23 and the second conveyor belt 24 can be limited.

[0030] like Figure 1 and Figure 2As shown, in some embodiments, the double-row belt synchronous conveyor also includes a drive structure 30, which is disposed on the mounting part 25 and is connected to the drive roller 21 for driving the drive roller 21 to rotate. The mounting part 25 includes a first mounting plate 251 and a second mounting plate 252. The second mounting plate 252 has two sets and is disposed opposite to each other on the support frame 10. The first mounting plate is also disposed on the support frame 10 to achieve stable support.

[0031] like Figure 1 and Figure 2 As shown, in some embodiments, the drive structure 30 includes a drive motor 31, a first pulley 32, a drive belt 33, and a second pulley 34. The drive motor 31 is mounted on a first mounting plate 251, and the drive motor 31 and the first pulley 32 are connected in a transmission connection. Specifically, the first mounting plate 251 is provided with an opening, and the output shaft of the drive motor 31 is keyed to the first pulley 32. The drive belt 33 meshes with the first pulley 32 and the second pulley 34. As the first pulley 32 rotates, the second pulley 34 rotates.

[0032] like Figure 2 and Figure 3 As shown, in some embodiments, the first set of second mounting plates 252 has a through hole, through which the first end of the drive roller 21 passes and is keyed to the second pulley 34. A bearing seat is embedded in the second set of second mounting plates 252 to allow the second end of the drive roller 21 to be rotatably mounted. As the second pulley 34 rotates, the drive roller 21 rotates synchronously, thereby moving the first conveyor belt 23 and the second conveyor belt 24 mounted on it, ultimately achieving the conveying of the product.

[0033] like Figure 2 As shown, in some embodiments, the roller tensioning seat 26 has four sets, which are arranged opposite to each other on the support frame 10. There are two sets of driven rollers 22, which are respectively arranged on both sides of the driving roller 21. Both ends of each set of driven rollers 22 are rotatably arranged in the roller tensioning seat 26. The driven rollers 22 and the driving roller 21 work together to tension the first conveyor belt 23 and the second conveyor belt 24. The distance between the other two sets of driven rollers 22 can be adjusted by the roller tensioning seat 26, thereby adjusting the tension.

[0034] like Figure 2 and Figure 3As shown, in some embodiments, the double-row belt synchronous conveyor further includes a tensioning structure 40. The tensioning structure 40 includes two sets of tensioning rollers 41 and two sets of fixing seats 42. The two sets of fixing seats 42 are respectively arranged in a one-to-one correspondence with the two sets of tensioning rollers 41, and the fixing seats 42 are located in the middle of the tensioning rollers 41. The fixing seats 42 divide the tensioning rollers 41 into two parts, corresponding to the first conveyor belt 23 and the second conveyor belt 24 respectively. At the same time, the fixing seats 42 can make the installation of the tensioning rollers 41 more stable.

[0035] like Figures 1 to 3 As shown, in some embodiments, both sets of fixed seats 42 have a first waist hole through which the tension roller 41 passes. Both sets of second mounting plates 252 are provided with second waist holes 2521, and both ends of the tension roller 41 are respectively installed in the second waist holes 2521 on the two sets of second mounting plates 252. The design of the first and second waist holes 2521 allows for adjustable contact between the tension roller 41 and the first conveyor belt 23 and the second conveyor belt 24, thereby adjusting the tension.

[0036] Figure 4 The arrangement of the first conveyor belt 23, the drive roller 21, the driven roller 22, and the tension roller 41 is shown. As the drive roller 21 rotates, the drive roller 21, the driven roller 22, and the tension roller 41 all exert force on the first conveyor belt 23, achieving the conveying function of the first conveyor belt 23 through friction. The distance between the two sets of tension rollers 41 can be adjusted through the first and second waist holes 2521, thereby adjusting the degree of contact with the first conveyor belt 23.

[0037] like Figures 1 to 3 As shown, in some embodiments, the conveying structure 20 further includes a belt support plate 28, which is fixed to the support frame 10. The belt support plate 28 can distribute the weight of the first conveyor belt 23, the second conveyor belt 24, and large-sized products, reducing the sagging and deformation of the first conveyor belt 23 and the second conveyor belt 24, and ensuring stable sag during operation. Two sets of fixing seats 42 are fixed on the belt support plate 28, and both sets of fixing seats 42 are arranged towards the direction close to the drive roller 21. The two sets of fixing seats 42 are respectively arranged on both sides of the drive roller 21, and the fixing seats 42 are used to provide auxiliary support for the two sets of tension rollers 41.

[0038] like Figure 2 As shown, in some embodiments, the conveying structure 20 further includes a photoelectric sensor 29, which is mounted on the belt support plate 28. The photoelectric sensor 29 is used to detect whether there are products on the first conveyor belt 23 and the second conveyor belt 24. The double-row belt synchronous conveying device also includes a PLC control cabinet. The photoelectric sensor 29 transmits the detection signal to the PLC control cabinet. When the photoelectric sensor 29 detects an abnormal signal, the PLC control cabinet controls the drive motor 31 to stop urgently.

[0039] like Figure 1 and Figure 2 As shown, in some embodiments, when large-sized products are conveyed, part of them are located on the first conveyor belt 23 and part of them are located on the second conveyor belt 24. The belt support plate 28 has a detection elongated hole 281, which is located between the first conveyor belt 23 and the second conveyor belt 24. The detection port of the photoelectric sensor 29 is aligned with the detection elongated hole 281. This design enables the photoelectric sensor 29 to accurately detect whether there are products on the first conveyor belt 23 and the second conveyor belt 24.
