[0056] In the following description, numerous specific details are provided to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention can be practiced without one or more of these details. In other instances, certain technical features known in the art are not described to avoid confusion with the present invention.

[0057] To provide a thorough understanding of the present invention, a detailed description will be provided in the following description. It is apparent that the implementation of the present invention is not limited to the specific details familiar to those skilled in the art. Preferred embodiments of the present invention are described in detail below, but in addition to these detailed descriptions, the present invention may also have other embodiments.

[0058] It should be noted that the terms used herein are only for the purpose of describing specific embodiments and are not intended to limit exemplary embodiments according to the present invention. As used herein, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form.

[0059] Ordinal numbers such as "first" and "second" cited in the present invention are merely identifiers and do not have any other meanings, such as a specific order, etc. Moreover, for example, the term "first component" itself does not imply the existence of a "second component", and the term "second component" itself does not imply the existence of a "first component".

[0060] It should be noted that the terms "upper", "lower", "front", "back", "left", "right", "inside", "outside" and similar expressions used in this document are for illustrative purposes only and are not limiting.

[0061] Now, exemplary embodiments according to the present invention will be described in more detail with reference to the accompanying drawings. However, these exemplary embodiments may be implemented in a variety of different forms and should not be construed as being limited to the embodiments described herein. It should be understood that these embodiments are provided to make the disclosure of the present invention thorough and complete and to fully convey the concepts of these exemplary embodiments to those of ordinary skill in the art.

[0062] like Figures 1 to 11 As shown, the present invention provides a conveyor belt 1, which mainly includes a series of slats 10 and a series of rods 20, wherein the series of rods 20 are connected in sequence, and the series of slats 10 are adjacent in sequence and connected by the series of rods 20 to form an endless conveyor belt 1. Figure 2 As shown, each rod 20 is parallel to the length of the corresponding slat 10. A series of rods 20 are connected in sequence to form an annular frame structure 2, and a series of slats 10 can be supported by the frame structure 2. The frame structure 2 can also be connected to a transmission component, which is connected to a drive device. Thus, the drive device can drive the transmission component to move, thereby driving the conveyor belt 1 connected to the transmission component to move.

[0063] The series of slats 10 have a working surface F1 for carrying objects and a non-working surface F2 opposite the working surface F1. A series of rods 20 are located on the side of the series of slats 10 that is adjacent to the non-working surface F2 and abut against the non-working surface F2. This allows the frame structure 2 formed by the series of rods 20 to directly support the slats 10, enhancing the structural strength of the slats 10. This provides the conveyor belt 1 with greater structural stability, ensuring smooth conveying.

[0064] Each pair of adjacent slats 10 is connected by a rod 20 and is rotatable relative to the rod 20 to which they are connected. It should be noted that "each adjacent" here refers to any two adjacent slats 10. For example, for any three adjacent slats 10, the middle slat 10 is adjacent to the slat 10 on one side and connected by one rod 20, and the middle slat 10 is adjacent to the slat 10 on the other side and connected by another rod 20. For ease of understanding, a slat 10 is selected from a series of slats 10 as the subject of description, namely, the selected slat 10a; and a rod 20 is selected from a series of rods 20 as the subject of description, namely, the selected rod 20a. In other words, the series of slats 10 includes the selected slat 10a, and the series of rods 20 includes the selected rod 20a. The selected rod 20a is located on the side of the non-working surface F2 of the selected slat 10a, and the selected slat 10a is rotatably connected to the selected rod 20a. Further, the selected slat 10a is rotatable around the central axis of the selected rod 20a within a certain angular range.

[0065] The length of the rod 20 is greater than the length of the slat 10, and the rod 20 extends beyond the two ends of the slat 10 in the length direction. In order to realize the connection of a series of rods 20, such as Figure 3 and Figure 5 As shown, the two ends of the rod 20 are bent to form locking hooks 21, and a series of rods 20 are connected in sequence through the locking hooks 21.

[0066] In order to realize the movable connection between the slats 10 and the rods 20, as shown in FIG. Figure 3 and Figure 8 As shown, the conveyor belt 1 further includes a plurality of connecting plates 30. The connecting plates 30 are located on the side of the non-working surface F2 of the series of slats 10 and extend away from the non-working surface F2. Specifically, the connecting plates 30 are arranged along the width of the slats 10 and optionally extend perpendicular to the non-working surface F2, i.e., the connecting plates 30 are perpendicular to the slats 10. Alternatively, the connecting plates 30 are slightly inclined relative to the slats 10.

[0067] Each slat 10 is connected to a connecting plate 30 for movable connection with a corresponding rod 20 via the connecting plate 30. The connecting plates 30 of two adjacent slats 10 are offset along the length of the slats 10 so that the connecting plates 30 of the two slats 10 are connected to different positions on the rod 20 to avoid interference. Optionally, a series of slats 10 have the same length, and the odd-numbered slats 10 are offset from the even-numbered slats 10 along the length of the slats 10 so that the connecting plates 30 are offset along the length of the slats 10.

[0068] For example, Figure 4 and Figure 6 As shown, the connecting plate 30 is provided with a pair of hook-shaped portions 33, namely a first hook-shaped portion 34 and a second hook-shaped portion 35; the pair of hook-shaped portions are arranged oppositely along the width direction of the slat 10. Figure 9 and Figure 10 As shown, the slat 10 is hooked to an adjacent rod 20 by one of its pair of hook-shaped portions 33, and the slat 10 is hooked to another adjacent rod 20 by the other of its pair of hook-shaped portions 33. In this way, a single slat 10 is fixed to the adjacent rod 20, so that a series of slats 10 can be connected in series through a series of rods 20 to form the conveyor belt 1.

[0069] To ensure a stable connection between the connecting plate 30 and the rod 20, the hooking surfaces 36 of the hook portions 33 are designed to match the shape and dimensions of the corresponding surfaces of the rod 20. Specifically, each hook portion 33 has a curved hooking surface 36, and each rod 20 has a curved or circular attachment surface 22. The hooking surfaces 36 of the hook portions 33 are slidably attached to the attachment surface 22 of the rod 20 in at least the circumferential direction of the rod 20, allowing the slats 10 connected to the connecting plate 30 to rotate relative to the rod 20. The illustrated example shows a cylindrical rod 20, so that the attachment surfaces 22 at various locations on the rod 20 are circular. Of course, if needed and / or desired, the rod 20 can be shaped differently, such as a prismatic rod; in this case, the portion of the rod 20 that engages the hook portion 33 is designed to have a curved or circular attachment surface 22. The reference circles where the hook surface 36 and the corresponding attachment surface 22 are located are preferably concentric circles. In this way, during the relative rotation of the slat 10, there can always be a large contact area between the hook surface 36 and the attachment surface 22, so that the rotation of the slat 10 relative to the rod 20 remains stable, and the supporting force of the rod 20 on the slat 10 is uniform to better support the slat 10, so that the conveyor belt 1 can maintain a smoother transportation.

[0070] One hook portion 33 is selected from the pair of hook portions 33 as the object of description, namely, the selected hook portion 33a. That is, the pair of hook portions 33 includes the selected hook portion 33a. The selected slat 10a is hooked to the selected rod 20a via the selected hook portion 33a. The attachment surface 22 of the selected rod 20a has the farthest point P in the direction perpendicular to the non-working surface F2 of the selected slat 10a. Figure 9 The schematic diagram shows the approximate location of the farthest point P. To prevent the connecting plate 30 from falling off the rod 20, the hook surface 36 of the hook portion 33a is designed to cover the area of ​​the attachment surface 22 on both sides of the farthest point P. This arrangement ensures that the hook portion 33a's hook surface 36 always covers the area of ​​the attachment surface 22 on both sides of the farthest point P, whether the slat 10 is horizontal or rotated relative to the rod 20. This ensures that the hook portion 33 is firmly hooked to the rod 20, preventing the connecting plate 30 from falling off the rod 20, thereby ensuring smooth conveyance and preventing the slat 10 from falling off the rod 20 when subjected to external forces. This prevents unexpected malfunctions, improves conveyor safety, and ensures normal operation. The hook portion 33 includes a hook tip 37 that covers the area of ​​the attachment surface 22 on either side of the farthest point P. The hook portion 33 has a force at the hook tip 37 toward the center of the rod 20 . This force has a component parallel to the non-working surface F2 of the slat 10 , which can stably hook the hook tip 37 of the hook portion 33 onto the rod 20 .

[0071] To ensure that the hook surface 36 covers the area on both sides of the attachment surface 22 at the farthest point P, the arc of the hook surface 36 of the hook portion 33 is preferably greater than 90°. For example, the arc can be 95°, 100°, 105°, 110°, 115°, 120°, etc. The hook portion 33 can cover the arc surface of the rod 20 that is greater than 90°.

[0072] The connecting plates 30 are located at the ends of the slats 10, connecting them to the rods 20 and preventing deformation, such as warping, at the ends. The connecting plates 30 can also be located in the middle of the slats 10, connecting them to the rods 20 and preventing deformation, such as warping. This arrangement provides a more stable connection between the slats 10 and the rods 20, effectively preventing the slats 10 from falling off the rods 20. The illustrated example shows the connecting plates 30 located at two spaced-apart locations in the middle of the slats 10. It should be noted that the middle of the slats 10 can be understood as the portion excluding the ends.

[0073] Each adjacent two slats 10 serve as a first slat 11 and a second slat 12 . The first slat 11 has a first connecting plate 31 at a selected position, and the second slat 12 has a second connecting plate 32 at the same selected position. The first connecting plate 31 and the second connecting plate 32 abut against each other at the hook portion 33 .

[0074] Return to see Figure 4 The connecting plate 30 is formed integrally with the slat 10. For example, as shown in the figure, the connecting plate 30 can be formed by bending both ends of the slat 10 toward the side where the non-working surface F2 is located, so that the connecting plate 30 is located at both ends of the slat 10. Figure 6 and Figure 8 The conveyor belt 1 also includes a fixing member 40, which is constructed separately from the slats 10 and connected to the slats 10. The fixing member 40 is a separate component. The connecting plate 30 is formed on the fixing member 40. The fixing member 40 is located in the middle of the slats 10, thereby positioning the connecting plate 30 in the middle of the slats 10. The fixing member 40 includes a fixing plate 43 connected to the connecting plate 30. The fixing plate 43 extends parallel to the non-working surface F2 and is located on one side of the connecting plate 30 along the length of the slats 10, resulting in an angular shape for the fixing member 40. The fixing plate 43 can be secured to the slats 10 by welding or fasteners such as screws or bolts. The illustrated example shows that the fixing plate 43 is provided with fixing holes 3, which can be welded to the slats 10 through the fixing holes 3. This arrangement makes welding easier and the welded structure more stable and reliable. The fixing plate 43 is located between two adjacent rods 20 but does not affect the relative movement between the slats 10 and the rods 20.

[0075] The fixing member 40 includes a plurality of first fixing members 41 and second fixing members 42. The first fixing members 41 are connected to the first slat 11, and the second fixing members 42 are connected to the second slat 12. The first fixing members 41 and the second fixing members 42 are arranged in opposite directions so that the connecting plates 30 on the first fixing members 41 and the second fixing members 42 are close to or abut against each other (see Figure 10 ). Figure 3 and Figure 8 It is schematically shown that two columns of fixing members 40 are provided on a series of slats 10 , and each column of fixing members 40 includes a plurality of groups of first fixing members 41 and second fixing members 42 arranged oppositely.

[0076] In order to prevent the series of slats 10 from shifting relative to the rod 20 in the longitudinal direction of the slats 10, the rod 20 is provided with at least one pair of limiting surfaces 50 facing opposite directions in the longitudinal direction of the rod 20. Each pair of limiting surfaces 50 abuts against the connecting plate 30 hooked at different positions on the rod 20. It should be noted that different positions refer to positions spaced a certain distance apart, for example Figure 8 The positions of the two rows of connecting plates 30 shown are those at the two ends of the rod 20, rather than the positions where two connecting plates 30 abut each other. With this arrangement, the limiting surfaces 50 can limit the position of the connecting plates 30, thereby limiting the position of the slats 10, preventing the slats 10 from shifting relative to the rod 20 in the longitudinal direction of the slats 10, and maintaining a stable relative position between the slats 10 and the rod 20. Figure 3 The single rod 20 is shown as being provided with a pair of stop surfaces 50, namely a first stop surface 51 and a second stop surface 52, respectively located at the two ends of the rod 20 so as to abut against the connecting plates 30 at the two ends of the slat 10. Alternatively, a stop surface 50 may be provided between the two ends of the rod 20 so as to abut against the connecting plate 30 located in the middle of the slat 10.

[0077] Alternatively, as Figure 7 and Figure 11 As shown, the conveyor belt 1 also includes a limiter 53, which is constructed separately from the rod 20 and connected to the rod 20. The limiter 53 is an independent component. A limit surface 50 is formed on the limiter 53. Specifically, the side of the limiter 53 facing the length direction of the rod 20 is the limit surface 50. For example, a separate rod 20 is provided with a limiter 53 at its two ends, and the limit surface 50 of each limiter 53 abuts against the connecting plate 30 hooked to the end of the rod 20. The illustrated example shows that the limiter 53 is provided with a fixing hole 3, and the limiter 53 can be welded to the slat 10 from the fixing hole 3. With this arrangement, welding is easier to operate and the welded structure is more stable and reliable. The limiter 53 does not affect the relative movement between the slat 10 and the rod 20.

[0078] Alternatively, in an example not shown, the rod 20 is configured to have a radially protruding convex portion, and the limiting surface 50 is formed on the convex portion. For example, a single rod 20 is provided with a convex portion at each end thereof, and the limiting surface 50 of each convex portion abuts against the connecting plate 30 hooked to the end of the rod 20.

[0079] At least one pair of limiting surfaces 50 is provided for every N number of rods 20 in the series, where 2 ≤ N ≤ 8. Specifically, N is the number of rods 20 without limiting surfaces 50 located between two rods 20 with limiting surfaces 50. For example, the number of rods 20 between two rods 20 with limiting members 53 is N, and at least two limiting members 53 are provided for every N number of rods 20. N can be set to 2, 3, 4, 5, 6, 7, or 8 as needed. In the illustrated example, N is 4.
