[0034] In the related art, the driving motor drives the chains on both sides of the chain to rotate through a transmission shaft. However, the driving motor is relatively large in volume and occupies a large installation space.

[0035] To solve the above problems, the embodiments of this application provide a tray conveying device and a conveying system. The solutions provided by the embodiments of this application will be described in detail below with reference to the accompanying drawings of the specification.

[0036] Figure 1 is a schematic structural diagram of a tray conveying device provided by an embodiment of this application; Figure 2 is Figure 1 a schematic diagram of the transmission assembly 200 in

[0037] Refer to Figure 1As shown, in a first aspect, an embodiment of the present application provides a tray conveying device, which includes a frame 100, a transmission assembly 200, and an electric roller 300. Among them, the transmission assembly 200 is connected to the frame 100. Specifically, the transmission assembly 200 includes at least two guide wheels 210 and a circulating mechanism 220. At least two guide wheels 210 are oppositely arranged on the frame 100 along a first direction, and the circulating mechanism 220 is wound around at least two guide wheels 210. For example, the transmission assembly 200 includes two guide wheels 210. The two guide wheels 210 are respectively installed at both ends of the frame 100 through rotating shafts or fixed seats, and the two guide wheels 210 are oppositely arranged along the first direction. The circulating mechanism 220 is wound around the two guide wheels 210.

[0038] It should be noted that the first direction can be referred to Figure 1 as shown by the x-direction in. In addition, the electric roller 300 is connected to the frame 100, the electric roller 300 is connected to the circulating mechanism 220, and the electric roller 300 drives the circulating mechanism 220 to rotate around the guide wheel 210. Exemplarily, the mounting shafts at both ends of the electric roller 300 are fixedly installed on the frame 100, the sprocket of the electric roller 300 is cooperatively connected with the circulating mechanism 220, and the electric roller 300 drives the circulating mechanism 220 to rotate around the guide wheel 210 during the rotation process.

[0039] It can be understood that, compared with the prior art, the tray conveying device of the present application uses the electric roller 300 to drive the circulating mechanism 220 to rotate, and the complexity of its overall structure is low, which is beneficial to reducing the overall failure rate. And compared with the design of the drive motor and the transmission shaft in the prior art, the electric roller 300 in the tray conveying device of the present application has a smaller volume, which is beneficial to saving the overall installation space.

[0040] In addition, exemplarily, the frame 100 includes a plurality of cross beams and a plurality of longitudinal beams, and the plurality of cross beams and the plurality of longitudinal beams are sequentially connected to form the frame 100. The cross beams and the longitudinal beams can be steel profiles.

[0041] Exemplarily, the circulating mechanism can be configured as a chain mechanism or a synchronous belt mechanism. Correspondingly, the guide wheel can be a sprocket or a synchronous belt wheel, which respectively act as driving parts to drive the chain mechanism or the synchronous belt mechanism to rotate around it.

[0042] In some examples, there are at least two groups of the transmission assembly 200. At least two groups of the transmission assembly 200 are arranged at intervals on the frame 100 along a second direction, and all the circulating mechanisms 220 are connected to the electric roller 300. Continuing to refer to Figure 1 as shown, exemplarily, the tray conveying device includes two groups of the transmission assembly 200. The two groups of the transmission assembly 200 are fixedly arranged on the upper surface of the frame 100, and the two groups of the transmission assembly 200 are oppositely arranged at a certain distance interval.

[0043] In this example, sprockets are respectively connected to both ends of the electric roller 300. The sprockets at both ends of the electric roller 300 are respectively in mating connection with the circulating mechanism 220 of the drive assembly 200 at corresponding positions. During the rotation of the electric roller 300, the circulating mechanism 220 is driven to rotate through the sprockets. It should be noted that the second direction can be referred to Figure 1 as shown by the y direction in

[0044] In some other examples, there are at least two sets of drive assemblies 200. The at least two sets of drive assemblies 200 are arranged at intervals along the second direction on the frame 100, and all the circulating mechanisms 220 are connected to the electric roller 300. Specifically, there are two sets of drive assemblies 200. The guide wheels 210 of the two sets of drive assemblies 200 are respectively fixedly connected to both ends of the synchronous shaft. The sprocket at the end of the electric roller 300 is in mating connection with at least one of the circulating mechanisms 220 of the two sets of drive assemblies 200. That is to say, the electric roller 300 drives one set of the circulating mechanism 220 to rotate around the corresponding guide wheel 210 through the sprocket, and the guide wheel 210 drives the circulating mechanism 220 of the other set of drive assemblies 200 to rotate through the synchronous shaft.

[0045] In some other examples, the electric roller 300 is arranged at the end of the frame 100, and both ends of the electric roller 300 are directly or indirectly connected to the corresponding guide wheels. The electric roller 300 drives the guide wheel 210 to rotate, and the rotation of the guide wheel 210 further drives the circulating mechanism 220 to rotate, thereby conveying the tray.

[0046] In some examples, there are also at least two support plates on the tray conveying device. The at least two support plates are respectively fixedly connected to the frame 100, and all the support plates are respectively located below the upper turning surfaces of all the circulating mechanisms 200, and are used to form a support for the upper turning surfaces of the circulating mechanisms (220). That is to say, each support plate is located between the upper turning surface and the lower turning surface of the circulating mechanism 200 at the corresponding position, and is used to support the upper turning surface to prevent it from sagging excessively due to its own gravity and the pressure of the tray.

[0047] Continue to refer to Figure 1 and Figure 2 As shown, in some examples, the tray conveying device further includes two mounting plates 400. The two mounting plates 400 are respectively fixedly installed on both sides of the frame 100, both are located below the drive assembly 200, and the positions of the two mounting plates 400 are opposite. The mounting shafts at both ends of the electric roller 300 are respectively fixedly connected to the frame 100.

[0048] Continue to refer to Figure 1 and Figure 2As shown, in some examples, the tray conveying device further includes a tensioning assembly 500. The tensioning assembly 500 includes a tensioning wheel 510 and a mounting seat 520. The tensioning wheel 510 is rotatably connected to the mounting seat 520 through a rotating shaft. The mounting seat 520 is slidably connected to the mounting plate 400, and the mounting seat 520 is selectively movable along the mounting plate 400 so that the tensioning wheel 510 abuts against the circulating mechanism 220, adjusting the tension of the circulating mechanism 220, ensuring that the circulating mechanism 220 has a large wrapping angle on the sprocket of the electric roller 300, and thus avoiding relative sliding between the sprocket and the circulating mechanism 220.

[0049] Exemplarily, the mounting plate 400 is provided with a sliding groove for adjusting the position of the mounting seat 520. The mounting seat 520 can move in the sliding groove to select an appropriate fixed position to ensure that the tensioning wheel 510 on the mounting seat 520 can abut against the circulating mechanism 220 and enable it to wrap around the sprocket of the electric roller 300. As Figure 2 shown, a horizontal sliding groove is provided on the mounting plate 400. The mounting seat 520 can move in the horizontal direction along the sliding groove, and thus can adjust the intensity of the tensioning wheel 510 abutting against the circulating mechanism 220.

[0050] As Figure 2 shown, in some other examples, there are at least two tensioning assemblies 500. The at least two tensioning assemblies 500 are respectively arranged on both sides of the electric roller 300. As Figure 2 shown, one tensioning assembly 500 is arranged on each of the left and right sides of the tensioning wheel 510. Each tensioning assembly 500 abuts against the circulating mechanism 220, enabling the circulating mechanism 220 to stably wrap around the sprocket of the electric roller 300, and thus ensuring stable power transmission between the electric roller 300 and the circulating mechanism 220.

[0051] In a second aspect, the embodiments of the present application provide a conveying system, including the tray conveying device of the first aspect. Since this conveying system includes the tray conveying device in any of the above technical solutions, it thus has all the beneficial effects of the electric roller 300 in any of the above technical solutions, which will not be elaborated here.

[0052] It is easy to understand that those skilled in the art can combine, split, recombine, etc. the embodiments of the present application based on several embodiments provided by the present application to obtain other embodiments, and these embodiments do not exceed the protection scope of the present application.

[0053] The above specific implementation manners have further elaborated in detail the purpose, technical solutions, and beneficial effects of the embodiments of the present application. It should be understood that the above are only the specific implementation manners of the embodiments of the present application, and are not used to limit the protection scope of the embodiments of the present application. Any modifications, equivalent replacements, improvements, etc. made on the basis of the technical solutions of the embodiments of the present application should be included within the protection scope of the embodiments of the present application.
