Detailed Implementation
[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the following provides a more detailed description of the utility model. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of the utility model.
[0019] Please see Figure 1-5 This utility model provides a technical solution: a guide trough for a roller conveyor, including a base plate 1, a roller conveyor 3 fixedly installed on the upper surface of the base plate 1, and an outer frame 2 welded and fixed to the upper outer side of the roller conveyor 3. A receiving plate 10 is fixedly installed between the outer frame 2 and the roller conveyor 3. Movable plates 4 are movably arranged on both sides of the upper end of the roller conveyor 3. A drive component for moving the movable plate 4 is provided at the upper end of the movable plate 4, and a guide mechanism is provided on the outer side of the movable plate 4.
[0020] In this embodiment, an outer frame 2 is provided on the outside of the roller conveyor 3, and movable plates 4 are movably provided on both sides of the upper end of the roller conveyor 3. At the same time, a drive assembly for moving the movable plates 4 is provided on the upper end of the movable plates 4. Under the action of the drive assembly, the two movable plates 4 can move closer or further apart at the upper end of the roller conveyor 3. Thus, when the transported items are transported on the roller conveyor 3, the distance between the two movable plates 4 can be adjusted according to the size of different items, thereby avoiding the deviation of the items during transport and ensuring high efficiency and positional accuracy when transporting items.
[0021] Specifically, the drive assembly includes a bidirectional lead screw 7 rotatably mounted directly above the outer frame 2. Movable parts 71 are screwed onto the outer surfaces of both ends of the bidirectional lead screw 7. A connecting column 6 is fixedly mounted at the lower end of the movable part 71. A fixed platform 5 is fixedly mounted on the side surface of the movable plate 4. The lower end of the connecting column 6 is fixedly connected to the upper surface of the fixed platform 5. A movable groove 21 is opened at the upper end of the outer frame 2, and the connecting column 6 is movably positioned inside the movable groove 21. A threaded hole adapted to the bidirectional lead screw 7 is opened inside the movable part 71. The drive assembly also includes a forward and reverse motor 92 fixedly mounted on the upper surface of the outer frame 2. A drive gear 9 is fixedly connected to the output shaft of the forward and reverse motor 92. A driven gear 91 is meshed with the outer side of the drive gear 9, and the driven gear 91 is fixedly sleeved at the middle position of the outer side of the bidirectional lead screw 7.
[0022] In this embodiment, by setting a drive assembly for moving the movable plate 4 on the outer frame 2, when an object is being conveyed on the roller conveyor 3, the forward and reverse motor 92 is started, which drives the drive gear 9 to rotate. Under the action of the drive gear 9 rotating, the driven gear 91 can be driven to rotate simultaneously, thereby driving the bidirectional lead screw 7 to rotate. The bidirectional lead screw 7 can drive the two movable parts 71 to move closer or further apart. At this time, the connecting column 6 moves inside the movable groove 21. Under the drive of the connecting column 6, the two movable plates 4 move closer or further apart, thereby adjusting the distance between the two movable plates 4 according to the object being transported on the roller conveyor 3, so that the object being transported is always in the correct transport position.
[0023] Specifically, the guiding mechanism includes several limiting grooves 22 opened on both sides of the outer frame 2. Each limiting groove 22 is movably inserted with a limiting rod 8. The end of the limiting rod 8 is fixedly connected to the side surface of the movable plate 4. The inner surface of the movable plate 4 is provided with a snap-fit groove 42. A rubber plate 41 is provided on the inner side of the movable plate 4. A snap-fit block 411 is provided on the rear side of the rubber plate 41. The snap-fit block 411 is inserted into the snap-fit groove 42. The snap-fit block 411 and the rubber plate 41 are integrally formed.
[0024] In this embodiment, a rubber plate 41 is provided on the inner side of the movable plate 4, and the movable plate 4 and the rubber plate 41 are connected to each other through the snap-fit groove 42 and the snap-fit block 411 to form a whole. The rubber plate 41 is soft, which can prevent the transported object from being damaged due to impact when the rubber plate 41 comes into contact with the transported object, thus increasing the protection performance of the overall device. At the same time, with the cooperation of the snap-fit groove 42 and the snap-fit block 411, when the rubber plate 41 is worn and cannot be used, it can be easily replaced. At the same time, with the cooperation of the limiting rod 8 and the limiting groove 22, the movable plate 4 can be made more stable during movement, avoiding the phenomenon of displacement.
[0025] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
