[0027] In order to make the above-mentioned objects, features and advantages of the present invention more clearly understood, the following describes in detail the specific embodiments of the present invention in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0028] Figure 1 A schematic structural diagram of the conveying device provided in this embodiment; Figure 2 This is a schematic diagram of the partial structure of the conveying device provided in this embodiment. Figure 1 and Figure 2 As shown, this embodiment provides a conveying device, including a base 100, a first bracket 200, a second bracket 300, a conveying assembly 400, a lifting frame 500 and a lifting cylinder 600, wherein the first bracket 200 and the second bracket 300 are fixedly arranged on the base 100 at intervals along a first direction; the conveying assembly 400 includes a mounting frame 410, a plurality of conveying rollers rotatably arranged on the mounting frame 410, and a flexible conveying body 420 supported by the plurality of conveying rollers, the plurality of conveying rollers are also arranged at intervals in the first direction, and at least one conveying roller is a power roller; the cylinder body of the lifting cylinder 600 is fixedly arranged relative to the second bracket 300, the lifting frame 500 is installed on the cylinder rod of the lifting cylinder 600, and the other end of the mounting frame 410 along the first direction is supported on the lifting frame 500; the lifting frame 500 is provided with a limiting structure 700 for limiting the movement of the mounting frame 410 along the second direction, the first direction is the conveying direction, and the second direction is perpendicular to the first direction.

[0029] When the material receiving height of the conveying device needs to be changed to accommodate feed ports at different heights, the lifting cylinder 600 can be activated, and the cylinder rod can be used to drive the lifting frame 500 to rise or fall. During this process, since one end of the mounting frame 410 is rotatably connected to the first bracket 200, and the other end of the mounting frame 410 is supported by the lifting frame 500, when the lifting frame 500 rises or falls, the end of the mounting frame 410 supported by the lifting frame 500 will follow the lifting frame 500 to achieve the change in the material receiving height, thereby meeting the material transfer requirements for feed ports at different heights. This setting can meet the transfer requirements of materials at different heights with a single set of conveying devices, so that after the height of the feed port is changed, there is no need to set up other conveying devices, which not only improves the efficiency of the production line, but also reduces costs.

[0030] In addition, by providing a limiting structure 700 on the lifting frame 500 for limiting the movement of the installation frame 410 along the second direction, the movement of the installation frame 410 in the direction perpendicular to the conveying direction is effectively restricted, which not only ensures the stability of the conveying component 400 during the material conveying process and reduces the shaking of the conveying component 400, but also improves the stability of the installation frame 410 during the lifting process.

[0031] It should be noted that, in this embodiment, the “first direction” can be Figure 1 and Figure 2 The arrows ab in the figure indicate that the “second direction” can be represented by Figure 1 and Figure 2 It is indicated by the arrow cd in the figure.

[0032] Please continue to refer to Figure 1 and Figure 2 In this embodiment, the conveying device may further include a support shaft 800 extending along the second direction, wherein the support shaft 800 is rotatably installed on the lifting frame 500, the mounting frame 410 is supported on the lifting frame 500 through the support shaft 800, and the limiting structure 700 is fixedly set on the support shaft 800.

[0033] The setting of the above-mentioned support shaft 800 realizes the support of the installation frame 410, so that in the process of lifting and lowering the installation frame 410 using the lifting frame 500, the sliding friction between the installation frame 410 and the lifting frame 500 will be converted into rolling friction, thereby effectively reducing the friction force during the lifting and lowering of the installation frame 410, not only reducing the noise during the lifting and lowering of the installation frame 410, but also reducing the wear and tear on the installation frame 410.

[0034] Please continue to refer to Figure 1In this embodiment, the mounting frame 410 may include a first vertical plate 411 and a second vertical plate 412 that are opposite to and spaced apart in the second direction, and a plurality of conveying rollers are rotatably connected between the first vertical plate 411 and the second vertical plate 412; the limiting structure 700 includes a first rotating wheel 710 and a second rotating wheel 720 that are fixedly sleeved on the support shaft 800, wherein the first rotating wheel 710 and the second rotating wheel 720 are arranged at intervals along the second direction, and a first wheel groove 711 for accommodating the first vertical plate 411 is opened on the circumference of the first rotating wheel 710, and a second wheel groove 721 for accommodating the second vertical plate 412 is opened on the circumference of the second rotating wheel 720.

[0035] This arrangement of the mounting frame 410 and the limiting structure 700 ensures that when the mounting frame 410 is supported on the support shaft 800, the first vertical plate 411 of the mounting frame 410 is inserted into the first wheel groove 711 of the first rotating wheel 710, and the second vertical plate 412 of the mounting frame 410 is inserted into the second wheel groove 721 of the second rotating wheel 720, that is, while the first rotating wheel 710 and the second rotating wheel 720 are used to support the mounting frame 410, the first rotating wheel 710 and the second rotating wheel 720 are also used to limit the mounting frame 410 along the second direction, which has a simple structure and reliable limiting.

[0036] Please continue to refer to Figure 1 and Figure 2 In this embodiment, the lifting frame 500 is in an "H" shape. The lifting frame 500 includes a first vertical plate 510 and a second vertical plate 530 that are opposite to and spaced apart from each other along the second direction, and a horizontal plate 520 fixedly connecting the first vertical plate 510 and the second vertical plate 530. Specifically, the first vertical plate 510 and the second vertical plate 530 form a receiving groove in the upper area of ​​the horizontal plate 520, and the support shaft 800 is accommodated in the receiving groove. The first end of the support shaft 800 is rotatably connected to the first vertical plate 510, and the other end of the support shaft 800 is rotatably connected to the second vertical plate 530. The first rotating wheel 710 and the second rotating wheel 720 are at least partially accommodated in the receiving groove; the horizontal plate 520 is connected to the cylinder rod of the lifting cylinder 600.

[0037] This arrangement of the lifting frame 500 can not only achieve reliable support for the mounting frame 410, but also utilize the upper area of ​​the horizontal plate 520 to accommodate the support shaft 800, the first rotating wheel 710 and the second rotating wheel 720, making the structure of the conveying device of this embodiment more compact and saving space.

[0038] Please continue to refer to Figure 1 and Figure 2In this embodiment, the second bracket 300 may include a first set of rods 310 and a second set of rods 320 arranged at intervals along the second direction. Specifically, the top of the first set of rods 310 is provided with a first guide hole extending along the lifting direction, and the top of the second set of rods 320 is provided with a second guide hole extending along the lifting direction, wherein the lower end of the first vertical plate 510 slides in cooperation with the first guide hole, and the lower end of the second vertical plate 530 slides in cooperation with the second guide hole.

[0039] This structural setting of the second bracket 300 is not only simple in structure, but also can guide the first vertical plate 510 and the second vertical plate 530 during the lifting process, so that the movement path of the lifting frame 500 is always along the lifting direction, so that the supporting force exerted on the mounting frame 410 is always vertically upward, avoiding poor movement due to the deflection of the mounting frame 410.

[0040] Please continue to refer to Figure 1 and Figure 2 In this embodiment, the second bracket 300 may further include a mounting plate 330, wherein the mounting plate 330 is fixedly connected to the first set of rods 310 and the second set of rods 320, the cylinder body of the lifting cylinder 600 is mounted on the mounting plate 330, and the cylinder rod of the lifting cylinder 600 extends upward from the mounting plate 330 and is connected to the cross bar 230 of the lifting frame 500.

[0041] By providing a mounting plate 330 in the second bracket 300 that is fixedly connected to the first set of rods 310 and the second set of rods 320, on the one hand, the structural strength and stability of the second bracket 300 can be increased, and on the other hand, an installation base can be provided for the lifting cylinder 600, thereby facilitating the arrangement of the lifting cylinder 600.

[0042] Please continue to refer to Figure 1 and Figure 2 In this embodiment, the cylinder rod of the lifting cylinder 600 is connected to the middle portion of the transverse plate 520 along the second direction. In other words, the cylinder rod of the lifting cylinder 600 is connected to the middle position of the transverse plate 520 of the lifting frame 500.

[0043] Through the above arrangement, the lifting driving force of the lifting cylinder 600 on the lifting frame 500 acts on the middle part of the lifting frame 500, so that the force on the lifting frame 500 is more balanced and the lifting stability is better.

[0044] Please continue to refer to Figure 1 and Figure 2In this embodiment, the first bracket 200 may include a first column 210 and a second column 220 arranged at intervals along the second direction, and a cross bar 230 fixedly connecting the first column 210 and the second column 220, wherein the first vertical plate 411 of the mounting frame 410 is rotatably connected to the first column 210, and the second vertical plate 412 of the mounting frame 410 is rotatably connected to the second column 220, and the rotation axes of the first vertical plate 411 and the second vertical plate 412 are collinear.

[0045] This arrangement of the first bracket 200 not only has a simple structure but also has good stability.

[0046] Please continue to refer to Figure 1 In this embodiment, the conveyor assembly 400 may further include a drive motor 430, wherein the drive motor 430 is mounted on the mounting frame 410, and the rotational output end of the drive motor 430 is drivingly connected to one of the plurality of conveyor rollers, and the plurality of conveyor rollers are transmission-connected. In other words, among the plurality of conveyor rollers of the conveyor assembly 400, one is a powered roller, and the remaining are unpowered rollers. Utilizing the transmission connection between the powered roller and the unpowered rollers, the rotational power of the powered roller can be transmitted to the remaining unpowered rollers, thereby achieving simultaneous rotation of the plurality of conveyor rollers.

[0047] This arrangement of the conveying assembly 400 can reduce the number of drive motors 430 that are required, thereby reducing the driving cost and also reducing the space occupied around the conveying device.

[0048] Specifically in this embodiment, there are two conveying rollers, and the two conveying rollers may be connected by a chain transmission mechanism. The flexible conveying body 420 may be a conveyor belt supported by the two conveying rollers.

[0049] Please continue to refer to Figure 1 and Figure 2 In this embodiment, the base 100 is a flat plate structure.

[0050] By setting the base 100 as a flat structure, on the one hand, the structure of the base 100 can be simplified, thereby reducing the manufacturing cost of the base 100. On the other hand, the contact area between the base 100 and the ground can be increased, thereby ensuring the working stability of the conveying device of this embodiment.
