Description

Technical Field

[0001] This utility model relates to the field of logistics, and in particular to a servo-driven moving blocking mechanism. Background Technology

[0002] Roller conveyors are commonly used equipment in the logistics field, mainly for material transport. For example, patent application number CN202320764611.8 discloses a lifting roller conveyor. During the material transport process, this roller conveyor can only transport materials from one end of the roller conveyor to the other end, and cannot stop the materials at different positions on the roller conveyor. However, in practical applications, it is often necessary to stop the materials at different positions on the roller conveyor to achieve different purposes. Therefore, there is an urgent need for a device that can stop the materials at different positions on the roller conveyor. Utility Model Content

[0003] (a) Technical problems to be solved

[0004] To address the shortcomings of existing technologies, the present invention aims to provide a servo-driven moving blocking mechanism that solves the problems existing in the prior art and, based on actual on-site needs, transfers materials to different positions on the roller conveyor.

[0012] (III) Beneficial Effects

[0013] 1. This utility model is installed on a roller conveyor. When the material is transported to different positions on the roller conveyor in cooperation with the roller conveyor, it is not necessary to set up multiple roller conveyors for alternating use. Only one relatively long roller conveyor is needed, so that the material can stop at different positions on the roller conveyor, which greatly saves manpower and material resources.

[0014] 2. This utility model, by setting the baffle plate to consist of a top plate, a bottom plate, a back plate, and rubber blocks, provides excellent blocking for materials, making the force on the materials more even and providing good protection for the materials, especially materials packaged in cardboard boxes, which also provide excellent protection for the cardboard boxes; the rubber blocks make the contact surface between the baffle plate and the materials flexible, further enhancing the protection of the materials.

[0015] 3. This utility model, through the setting of two sets of cylinders and a shaping plate, when the material is blocked by the baffle plate, the two cylinders on the left and right start simultaneously. Their piston rods drive the shaping plate to move towards the material, pushing the material to the middle position of the roller conveyor, which plays a good role in correcting deviation and straightening the material that may not be straight, thus achieving a good shaping effect. A rubber layer is fixed on the surface of the shaping plate, making the contact between the shaping plate and the material flexible, which provides good protection for the material.

Detailed Implementation

[0021] The following will refer to the appendix in the embodiments of this utility model. Figure 1-4 The technical solutions in the embodiments of this utility model are clearly and completely described. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0022] This utility model provides a technical solution: a servo-driven moving blocking mechanism, including a support frame 1. A first support plate 2 and a second support plate 3 are fixed to the front and rear ends of the support frame 1, respectively. A through groove 4 is formed at the center of the second support plate 3, through which a servo motor 5 is fixed. A lead screw 6 is fixed on the rotating shaft of the servo motor 5. The front end of the lead screw 6 is rotatably connected to the second support plate 3. A matching nut seat 7 is provided on the lead screw 6, and a blocking structure 8 is fixed on the top surface of the nut seat 7. The tail end of the roller conveyor is fixed and supported by this servo-driven moving blocking mechanism. The bottom of the roller conveyor is supported and fixed by the first support plate 2 and the second support plate 3, wherein the heights of the first support plate 2 and the second support plate 3 are the same. The front end of the roller conveyor is supported by another support structure, which is the same height as the first support plate 2. During operation, the specific location on the roller conveyor to which the material needs to be transferred is first determined. Once the desired location is determined, the servo motor 5 starts, driving the lead screw 6 to rotate, which in turn moves the nut seat 7 forward. This, in turn, moves the blocking structure 8 fixed to the nut seat 7 forward until the blocking structure 8 reaches the required position. At this point, the servo motor 5 stops. The roller conveyor then transfers the material from the front to the rear. When the material contacts the blocking structure 8, it is stopped and stops moving backward, thus stopping the material at the designated location on the roller conveyor. The operator or machine operator at that location can then perform the appropriate operations and processing. By using this servo blocking mechanism, multiple roller conveyors are no longer needed for alternating material transfers; only a single, relatively long roller conveyor is required. Adding a servo blocking mechanism to the roller conveyor allows the material to stop at different locations, significantly saving manpower and resources. The length of the servo blocking mechanism is set according to actual needs.

[0023] The blocking structure 8 includes a movable plate 9 fixed to the top surface of the nut seat 7. The left and right ends of the movable plate 9 extend beyond the left and right sides of the support frame 1, respectively. Fixed rods 10 are fixed to both ends of the movable plate 9, with the front ends of the fixed rods 10 extending beyond the front ends of the movable plate 9. A triangular plate 11 is fixed to the top surface of the portion of the fixed rod 10 extending beyond the movable plate 9. A connecting plate 12 is fixed to the top of the triangular plate 11, and a blocking plate 13 is fixed between the two connecting plates 12. This is the specific structure of the blocking structure 8. A gap is left between the movable plate 9 and the blocking plate 13 for the roller conveyor to pass through. The bottom surface of the roller conveyor does not contact the movable plate 9, and the top surface of the roller conveyor does not contact the blocking plate 13. The blocking plate 13 effectively blocks the material, making the force on the material more even and providing good protection, especially for materials packaged in cardboard boxes, where it provides excellent protection for the cardboard boxes. The triangular plate 11 makes the overall structure of the blocking structure 8 more stable.

[0024] The top surface of the support frame 1 is fixed with slide rails 14 near the left and right edges, and the bottom surface of the movable plate 9 is fixed with sliders 15 that match the slide rails 14. The slide rails 14 and sliders 15 provide good guidance for the movable plate 9 and also greatly increase the overall stability of the blocking structure 8.

[0025] The baffle plate 13 includes a top plate 16 and a bottom plate 17 fixed between two connecting plates 12. A back plate 18 is fixed between the rear ends of the top plate 16 and the bottom plate 17. The left and right ends of the back plate 18 are respectively fixed to the left and right connecting plates 12. A rubber block 19 is fixed within the U-shaped frame formed by the back plate 18, the top plate 16, and the bottom plate 17. The front end of the rubber block 19 extends beyond the front end of the top plate 16. This arrangement makes the contact surface between the baffle plate 13 and the material flexible, further enhancing the protection of the material.

[0026] The connecting plate 12 includes a first connecting part 20 fixed to the top of the triangular plate 11 and a second connecting part 21 fixed to the first connecting part 20. A baffle plate 13 is connected between the two second connecting parts 21, and the baffle plate 13 is connected at a rear position of the second connecting parts 21. A cylinder 22 is fixed on the outer surface of the triangular plate 11. The piston rod of the cylinder 22 passes through the triangular plate 11, and a shaping plate 23 is fixed to the end of the piston rod of the cylinder 22. When the material is blocked by the baffle plate 13, the two cylinders 22 on the left and right start simultaneously. Their piston rods drive the shaping plate 23 to move in the direction of the material, pushing the material to the middle position of the roller conveyor, which plays a good role in correcting deviation and straightening the material that may not be straight, thus achieving a good shaping effect.

[0027] A rubber layer 24 is fixed to the surface of the shaping plate 23. The rubber layer 24 makes the contact between the shaping plate 23 and the material flexible, thus providing good protection for the material.

[0028] Working Principle: During operation, the specific location on the roller conveyor to which the material needs to be transferred is first determined. Once the desired location is determined, the servo motor 5 starts, driving the lead screw 6 to rotate, which in turn moves the nut seat 7 forward. This, in turn, moves the blocking structure 8 fixed on the nut seat 7 forward until the blocking structure 8 reaches the desired position. At this point, the servo motor 5 stops. The roller conveyor then transfers the material from the front to the rear. When the material contacts the blocking structure 8, it is stopped and stops moving backward, thus stopping the material at the designated location on the roller conveyor. The operator or machine operator at that location can then perform the appropriate operations and processing. By using this servo blocking mechanism, multiple roller conveyors are no longer needed for alternating material transfers. Only a single, relatively long roller conveyor is required. Adding a servo blocking mechanism to the roller conveyor allows the material to stop at different locations, significantly saving manpower and resources. The length of the servo blocking mechanism is set according to actual needs.
