Abstract
Description
Technical Field
[0001] This utility model relates to the field of push mechanism, specifically to a two-stage push rod conveying mechanism. Background Technology
[0002] Conventional conveyor systems have limited flexibility and cannot cope with ever-changing transportation needs, thus limiting their application scenarios. For example, mechanical conveyors such as belt conveyors, chain conveyors, and roller / roller conveyors are not fully suitable for working environments with confined spaces, complex paths, and high sealing requirements.
[0003] If hydraulic or pneumatic cylinders are used to place the guide rod within the space, and the supporting facilities often require the equipment to occupy a large installation space, especially if the material movement distance required within the space is too long, larger cylinders or hydraulic cylinders often require higher costs.
[0004] Therefore, a conveying mechanism with a large conveying stroke is needed. Utility Model Content
[0005] This utility model provides a two-stage push rod conveying mechanism. A support rod is installed on a moving block via a drive device, and a selectable push block is installed on the support rod. By changing the position of the push block, two-stage pushing is achieved, which can achieve a longer pushing distance.
[0006] This utility model is achieved through the following technical solution:
[0007] A two-stage push rod conveying mechanism includes,
[0008] A base, on which a support plate is provided, and on which a movable block is provided, and a support rod is fixedly connected to the movable block;
[0009] A pushing device is fixedly connected to the base and disposed below the support plate; the moving end of the pushing device is fixedly connected to the moving block.
[0010] A limiting plate is provided on both sides of the base, and the upper surface of the limiting plate is lower than the support plate;
[0011] The support rod has a push block rotatably connected to its free end. When the push block is in its natural state, its top is higher than the upper surface of the support plate. When the push block is pressed against the limiting plate, the push block rotates to below the limiting plate.
[0012] Furthermore, the pushing device includes a lead screw and a roller. The lead screw is rotatably connected to the base, and the roller is fitted onto the lead screw. The moving block is fixedly connected to the roller. One end of the lead screw passes through a fixed plate and is fixedly connected to a pulley, which drives the driving mechanism.
[0013] Furthermore, a slide rail is fixedly connected to the base, and a slider that cooperates with the slide rail is provided at the bottom of the push block.
[0014] Furthermore, the push block is arranged in the shape of a right triangle, with its hypotenuse facing the moving block in its natural state, and the push block is rotatably connected to the support rod via a pivot.
[0015] Furthermore, the support rod is also provided with a limiting block, which is located in front of the push block and below the rotating shaft. When the push block rotates against the conveyed object, its right-angled side abuts against the limiting block to limit its movement.
[0016] The beneficial effects of this utility model are as follows:
[0017] This invention utilizes a screw structure to achieve two-stage pusher conveying. In the first stage, a moving block on a roller pushes the material. As the material presses against the push block, it remains in place after detaching from the limiting plate. Once the first stage reaches its limit, the material is supported by a front support plate and a support plate to ensure it remains stationary. When the screw structure reverses, the moving block returns to its original position. At this point, when the push block is pressed against the limiting plate, it rotates to below the limiting plate. Then, the screw is rotated forward, and the moving block moves forward. After the push block detaches from the limiting plate, its top protrudes from the upper surface of the support plate, pushing the material forward from its tail. After the second stage reaches its limit, the screw drives the moving block back to its original position. Attached Figure Description

[0022] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.
[0023] like Figure 1-2 As shown, a two-stage push rod conveying mechanism includes,
[0024] A base 10, on which a support plate 101 is provided, a movable block 102 is provided on the support plate 101, and a support rod 103 is fixedly connected to the movable block 102;
[0025] Pushing device 20, which is fixedly connected to the base 10 and disposed below the support plate 101, and whose moving end is fixedly connected to the moving block 102;
[0026] Limiting plate 30, the limiting plate 30 is disposed on both sides of the base 10, and the upper surface of the limiting plate 30 is lower than the support plate 101;
[0027] The support rod 103 is rotatably connected to a push block 1031 at its free end. When the push block 1031 is in its natural state, its top is higher than the upper surface of the support plate 101. When the push block 1031 is pressed against the limiting plate 30, the push block 1031 rotates to below the limiting plate 30.
[0028] Specifically, this setup can push the material forward a second time by changing the position of pusher block 1031, forming a two-stage push, which is simple in structure.
[0029] Furthermore, the pushing device 20 includes a lead screw 201 and a roller 202. The lead screw 201 is rotatably connected to the base 10, and the roller 202 is fitted onto the lead screw 201. The moving block 102 is fixedly connected to the roller 202. One end of the lead screw 201 passes through a fixing plate 104 and is fixedly connected to a pulley 203. The pulley 203 drives a driving mechanism, which can be a stepper motor or a servo motor.
[0030] Furthermore, in order to ensure the stability of the movement, a slide rail 105 is fixedly connected to the base 10, and a slider 1021 that cooperates with the slide rail 105 is provided at the bottom of the push block 1031.
[0031] Furthermore, the push block 1031 is arranged in a right-angled triangle, with its hypotenuse facing the moving block 102 in its natural state. The push block 1031 is rotatably connected to the support rod 103 via a pivot 1032. By setting the hypotenuse to face the moving block 102, the limiting plate 30 can rotate through the inclined surface when returning to its original position, which is more convenient.
[0032] Furthermore, in order to ensure that the push block 1031 can withstand a large force when pushing the object, the support rod 103 is also provided with a limit block 1033. The limit block 1033 is located in front of the push block 1031 and below the rotating shaft 1032. When the push block 1031 rotates against the conveyed object, its right-angled side abuts against the limit block 1033 to limit its movement.
[0033] Specifically, such as Figure 3 In use, in the first stage, the lead screw 201 rotates forward, and the roller 202 drives the moving block 102 to push the material forward. When it is pushed to the limit position, the front part of the material rests on the front support (not shown in the figure). The lead screw 201 rotates in the reverse direction, and the moving block 102 returns to its original position. Since the push block 1031 can rotate, it does not affect its backward movement. When it moves into position, it is squeezed by the limiting plate 30. Then the lead screw 201 rotates forward. Since the push block 1031 is naturally higher than the upper surface of the support plate 101, it pushes the material again from behind during its forward movement for a second stage of forward movement.
[0034] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
