[0030] The following further elaborates on the content of the present utility model in conjunction with specific embodiments:

[0031] As shown Figure 1 in FIG. Figure 1 , a width-adjustable conveying device includes a conveyor belt main body 1. Different from the frame side frames with fixed pitches in the conventional technology, in this embodiment, the side frames on both sides of the conveyor belt main body 1, one side is a fixed side frame, defined as the fixed conveyor belt edge 2, and the other side is a movable side frame, defined as the movable conveyor belt edge 3.

[0032] Set the length direction of the conveyor belt as the vertical axis direction, and set the direction from the movable conveyor belt edge 3 to the fixed conveyor belt edge 2 as the horizontal axis direction. The vertical axis direction and the horizontal axis direction are perpendicular to each other; both the fixed conveyor belt edges 2 and the movable conveyor belt edges 3 on both sides are arranged along the vertical axis direction.

[0033] Refer to the attached Figure 3 drawing. Taking the fixed conveyor belt edge 2 as an example (the structure of the movable conveyor belt edge 3 is the same), the fixed conveyor belt edge 2 uses the long strip support block 21 as the main body to support the conveyor belt main body 1. A number of support rods 8 are arranged between the two long strip support blocks 21. The support rods 8 are arranged along the horizontal axis direction. One end of the support rod 8 is fixedly connected to the fixed conveyor belt edge 2, and the other end of the support rod 8 is movably inserted through the movable conveyor belt edge 3 through a bushing 7, so as to assist in supporting the conveyor belt main body 1. A side plate 22 is arranged outside the long strip support block 21 to reinforce the stable installation of the support rod 8.

[0034] When adjusting the width of the conveyor belt, the fixed conveyor belt edge 2 remains stationary. The structure for driving the movable conveyor belt edge 3 to move in the horizontal axis direction includes an adjustment driving mechanism 4 on the power side and a driven part 5 on the driven side. The adjustment driving mechanism 4 and the driven part 5 on the driven side are respectively arranged at the upstream and downstream ends of the conveyor belt main body 1. The power structure for adjusting the movement of the conveyor belt frame is concentrated at a corner of the movable end of the equipment, with a simple structure, automatic adjustment, and a convenient and efficient operation process.

[0035] Specifically, as shown in the attached Figure 2 drawing, the adjustment driving mechanism 4 includes a power rod 41. The power rod 41 is arranged along the horizontal axis direction. The two ends of the power rod 41 are respectively connected to the fixed conveyor belt edge 2 and the movable conveyor belt edge 3 on both sides through bearing assemblies. The two bearing assemblies are connected to the driven part 5 through a transmission part 6. The two groups of transmission parts 6 extend along the fixed conveyor belt edge 2 and the movable conveyor belt edge 3 respectively. The transmission part 6 adopts one of the ways including belt drive, gear drive, and chain drive. As shown in the attached Figure 1 drawing, in this embodiment, the transmission part 6 adopts a combination of a chain and a sprocket. The sprocket is sleeved on the power rod 41 through a connecting shaft.

[0036] The edge of the movable conveyor belt 3 is fixedly connected with a lining member, and the lining member is in threaded cooperation with the end of the power rod 41. The rotation of the power rod 41 drives the lining member to move linearly along the length direction of the power rod 41. The power side realizes linear width adjustment through the lining member, and drives the driven part 5 to synchronously adjust the width linearly through the transmission part 6, so as to drive the overall frame of the edge of the movable conveyor belt 3 to move away from or close to the edge of the fixed conveyor belt 2. Refer to the appendix Figure 5 The bushing 7 has a certain depth to form a sleeve. During the adjustment process, the end of the support rod 8 moves linearly in the bushing 7 to adapt to the width change.

[0037] Refer to the appendix Figure 4 Combined with the appendix Figure 7 As shown in the figure, the power rod 41 adopts a spline shaft, and the lining member adopts a combination of a spline sleeve 42 and an outer sleeve 43. The outer sleeve 43 includes a limiting section 431 and a connecting section 432 that are connected as a whole. The diameters of the two are different. The connecting section 432 is sleeved on the power rod 41 and is in threaded cooperation. A bearing 45 and a bearing sleeve 46 for fixing the bearing 45 are sleeved on the connecting section 432; the power rod 41 rotates and works under the drive of the motor 40. The outer sleeve 43 can move linearly along the power rod 41 while rotating due to the threaded connection of the connecting section 432 to the power rod 41. By setting the bearing 45, the outer bearing sleeve 46 and the long strip support block 21 fixedly connected to the bearing sleeve 46 move linearly together, so as to realize width adjustment. A plug cover 48 and a plug plate 49 are installed at the end of the outer sleeve 43 for limiting.

[0038] By setting the spline sleeve 42 and the outer sleeve 43 to overlap and nest in contact with the power rod 41, the contact area is increased, stress concentration is reduced, and the operating load of the movable end of the power side is balanced.

[0039] Specifically, refer to the appendix Figure 7 The spline sleeve 42 is partially inserted into the limiting section 431, and a retaining sleeve 44 is sleeved on the spline sleeve 42. The retaining sleeve 44 and the spline sleeve 42 are keyed; refer to the appendix Figure 6 On the inner wall of the spline sleeve 42, long convex strips are arranged along the length direction, so that the spline sleeve 42 is fixedly connected to the power rod 41 to keep synchronous rotation. Key grooves 47 are opened on the inner wall of the retaining sleeve 44 and the outer wall of the spline sleeve 42 to place key pins, so as to prevent the retaining sleeve 44, the spline sleeve 42 and the power rod 41 from being misaligned during rotation and ensure stable operation.

[0040] Among them, the bearing sleeve 46 is set as a T-shaped sleeve. The head of the T-shaped sleeve is arranged on the outer end side of the connecting section 432, and a convex ring 460 is arranged on the T-shaped body. The convex ring 460 is clamped at the connection between the limiting section 431 and the connecting section 432 and divides the bearing sleeve 46 into two parts. One part of the bearing sleeve 46 limits and fixes the internal bearing 45, and a plurality of bearings 45 are arranged in parallel (such as in the appendix Figure 7Three are shown in it), increasing the holding force; Another section of the bearing sleeve 46 is nested and installed with the limiting section 431 of the outer sleeve 43.

[0041] The above embodiments are only for illustrating the technical concept and features of the present invention, and the purpose is to enable those who are familiar with this technology to understand the content of the present invention and implement it accordingly, and it cannot be used to limit the protection scope of the present invention. For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and without departing from the spirit or basic features of the present invention, the present invention can be implemented in other specific forms. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting. The scope of the present invention is defined by the appended claims rather than the above description. Therefore, it is intended to include all changes falling within the meaning and scope of the equivalent elements of the claims in the present invention.
