Description

Technical Field

[0001] The utility model relates to the technical field of blocking mechanisms, and particularly relates to a gravity blocking mechanism. Background Art

[0002] In automated conveying systems such as logistics and production lines, it is usually necessary to set up blocking mechanisms to control the conveying path and process of materials; traditional blocking mechanisms mostly adopt manual or electric control methods, and realize the interception and release of materials through mechanical or electrical signals; however, manual control is complex and inefficient, and it is difficult to meet the requirements of large-scale automated production; although the electric control method improves the automation level, its structure is complex, the cost is high, and it is easy to affect normal conveying operations in case of power failure or failure.

[0003] In order to overcome these problems, some blocking devices based on the principles of gravity or mechanical linkage have emerged; such devices rely on the self-weight of materials or the triggering of external devices to realize passive automatic blocking and release functions; the gravity blocking mechanism can provide reliable material control effects while reducing the demand for external power, and has the advantages of simple structure, low cost, and low energy consumption. It is especially suitable for power failure scenarios or application environments sensitive to costs. However, existing gravity blocking devices often have problems such as insufficiently sensitive response and unstable blocking effect, and it is difficult to meet the requirements of high-speed and precise conveying.

[0004] Therefore, this application proposes a gravity blocking mechanism to realize the automatic blocking and release of materials, and at the same time improve the working efficiency and reliability of the equipment. Content of the Utility Model

[0005] In view of the deficiencies of the prior art, the utility model provides a gravity blocking mechanism, which solves the problems put forward in the above background art.

[0006] To achieve the above objectives, the utility model is realized through the following technical solutions:

[0007] A gravity blocking mechanism includes a bottom shaft, a movable shaft disposed inside the bottom shaft, and a shielding assembly;

[0008] The bottom shaft includes a bottom plate and a connecting frame. The connecting frame is installed on the bottom plate. One side edge of the connecting frame is flush with one side edge of the bottom plate. The inner bottom wall of the connecting frame is inclined from low to high starting from one side close to the edge of the bottom plate;

[0009] One end of the movable shaft is disposed inside the connecting frame and cooperates with the inner bottom wall of the connecting frame, and the other end is located outside the connecting frame;

[0010] The middle part of the shielding component is arranged on the top of the connecting frame through a rotating shaft, and the bottom of the shielding component contacts the upper surface of the movable shaft. When the movable shaft moves along the inner bottom wall of the connecting frame, the shielding component is urged to rotate with the connecting frame through the rotating shaft.

[0011] Optionally, the connecting frame includes a long plate, a short plate, a trapezoidal block and two square plates;

[0012] One side edge of the long plate is flush with one side edge of the bottom plate;

[0013] One short plate is symmetrically arranged with the long plate on the bottom plate;

[0014] One trapezoidal block is adaptively arranged in the middle of the connection between the long plate and the short plate;

[0015] The two square plates are symmetrically arranged on the surface of the trapezoidal block, and both side edges of the two square plates are connected to the edges of the long plate and the short plate.

[0016] Optionally, the height of the long plate is greater than the height of the short plate, and the height by which the long plate is greater than the short plate is adapted to the height of the shielding component.

[0017] Optionally, a movable hole is formed on the surface of the long plate.

[0024] The baffle is connected and arranged on one side of the L-shaped plate.

[0025] The present utility model provides a gravity blocking mechanism, which has the following beneficial effects:

[0026] 1. Through the coordinated cooperation among the connection frame, the movable shaft, and the shielding component, when two devices are docked, the docking device can trigger the movement of the sliding shaft, causing the movable shaft to roll along the axis. The movement of the movable shaft further lifts one side of the shielding component, enabling the shielding component to effectively overlap with the sliding shaft, and then driving the top of the shielding component to rotate and descend to the conveying surface, opening the blocking position, thereby allowing the goods to pass through smoothly. On the contrary, when the sliding shaft is not triggered, the shielding component continuously maintains an inclined state, with one end higher than the conveying surface, forming an effective material blocking effect. Through the above design, efficient automatic control of materials can be achieved, and the efficiency of device docking and material conveying can be improved. Description of the Drawings

[0034] In order to easily understand the technical means, creative features, achieved purposes, and effects of the present utility model, the present utility model will be further described below in conjunction with specific embodiments.

[0035] In the description of the present utility model, it should be understood that the orientation or positional relationships indicated by the terms "lateral", "longitudinal", "end", "edge", "side wall", "upper", "lower", "upper part", "lower part", "directly above", "surface", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "axial", "radial", "circumferential", "end", "head", "tail", etc. are based on the orientation or positional relationships shown in the drawings, and are only for the convenience of describing the technical solutions of the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present utility model.

[0036] This application proposes a gravity blocking mechanism, which is specifically as follows:

[0037] Reference can be made to Figure 1-2 , this application mainly consists of a bottom shaft 1, a movable shaft 2 arranged inside the bottom shaft 1, and a shielding assembly 3. Thus, by the movement of the movable shaft 2 inside the bottom shaft 1, the shielding assembly 3 is caused to change, achieving the effect of shielding materials or opening to allow materials to pass through.

[0038] Reference can be made to Figure 1-4 , the bottom shaft 1 mainly includes two parts, a bottom plate 11 and a connecting frame 12. The connecting frame 12 is installed on the bottom plate 11. One side edge of the connecting frame 12 is flush with one side edge of the bottom plate 11. The inner bottom wall of the connecting frame 12 is inclined from low to high starting from the side close to the edge of the bottom plate 11.

[0039] Furthermore, the connecting frame 12 specifically includes a long plate 121, a short plate 122, a trapezoidal block 123, and two square plates 124 connected to form a frame. One side edge of a long plate 121 is flush with one side edge of the bottom plate 11; a short plate 122 is symmetrically arranged with the long plate 121 on the bottom plate 11; a trapezoidal block 123 is adaptively arranged in the middle of the connection between the long plate 121 and the short plate 122; two square plates 124 are symmetrically arranged on the surface of the trapezoidal block 123, and both side edges of the two square plates 124 are connected to the edges of the long plate 121 and the short plate 122; among them, the height of the long plate 121 is greater than the height of the short plate 122, and the height difference between the long plate 121 and the short plate 122 is adapted to the height of the shielding assembly 3. Thus, when the movable shaft 2 pushes the shielding assembly 3 to move, one side of the shielding assembly 3 can directly abut against the upper side of the short plate 122 and then be flush with the height of the long plate 121, and the material can pass through smoothly.

[0040] Specifically, in order to complete the connection and cooperation between the connecting frame 12 and the movable shaft 2, a movable hole 1211 is provided on the long plate 121 of the connecting frame 12.

[0041] Reference can be made to Figure 5-6The movable shaft 2 includes a sliding block 21 and a push rod 22. The sliding block 21 is movable in the connecting frame 12. The lower surface of the sliding block 21 is adapted to the trapezoidal block 123 and is inclined. The upper surface of the sliding block 21 is horizontally arranged. One end of the push rod 22 is fixedly connected to the top of one side of the sliding block 21, and the other end passes through the movable hole 1211 and is located outside the connecting frame 12. When a force is applied to the push rod 22, the sliding block 21 is pushed to move along the inclined direction of the trapezoidal block 123, and the push rod 22 moves upward along the direction of the movable hole 1211.

[0042] It should be noted that the width of the sliding block 21 is greater than the width of the movable hole 1211 , so that the sliding block 21 can be shielded at the position where the long plate 121 is not opened, and the sliding block 21 can be lowered to completely cut out of the connection frame 12 .

[0043] Furthermore, in order to make the sliding block 21 more flexible during movement, a pulley is provided at the bottom of the sliding block 21 to increase the flexibility of sliding.

[0044] For reference Figure 5-6 When the push rod 22 is pushed to cause the sliding block 21 to move upward along the direction of the trapezoidal block 123, the shielding component 3 is pressed upward, causing the shielding component 3 to rotate; the specific shielding component 3 includes an L-shaped plate 31 and a baffle 32, and the two ends of the L-shaped plate 31 are connected to the two square plates 124 through a rotating shaft, and the baffle 32 is connected and arranged on one side of the L-shaped plate 31; the setting position of the L-shaped plate 31 is closer to the contact with the sliding block 21, and the L-shaped setting of the L-shaped plate 31 can cause a larger space during rotation. When the sliding block 21 does not move, it does not abut against the L-shaped plate 31. The L-shaped plate 31 naturally droops and tilts to a larger range, which can cause the baffle 32 at the other end to tilt upward to a higher height, which is conducive to better shielding work during work. In order to increase the flexibility of the L-shaped plate 31, a pulley is provided at the bottom of the side of the L-shaped plate 31 that preferentially contacts the sliding block 21, which can reduce the friction resistance between the sliding block 21 and the L-shaped plate 31 when the sliding block 21 moves, thereby increasing the continuity and flexibility of the work between the two.

[0045] When the sliding block 21 moves, it pushes the naturally drooping end of the L-shaped plate 31 to move upward, thereby causing the baffle 32 at the other end to droop downward and fall on the top of the short plate 122 to be flush. At this time, there is no shielding effect and materials can pass through without obstruction.

[0046] In the utility model, the working steps of the device are as follows:

[0047] 1. First, when implementing material blocking, the movable shaft 2 naturally slides along the inner bottom wall of the connection frame 12 of the bottom shaft 1. When the movable shaft 2 drops and changes occur, one end of the L-shaped plate 31 in the shielding component 3 supported also naturally sags along with the movable shaft 2. At this time, the baffle 32 in the shielding component 3 is lifted to form a shielding position.

[0048] 2. Second, when it is necessary to open the shielding formed by the baffle 32, force is applied to the push rod 22 in the movable shaft 2. At this time, based on the inclined slope where the sliding block 21 is adapted to the trapezoidal block 123, the sliding block 21 naturally moves upward. At this time, the push rod 22 successively enters and moves upward along the movable hole 1211.

[0049] 3. Then, during the upward movement of the sliding block 21, the L-shaped plate 31 is successively lifted. After the L-shaped plate 31 is lifted, the baffle 32 on the other side naturally sags. Until the push rod 22 pushes the sliding block 21 to the maximum position, the baffle 32 is lapped on the top of the short plate 122.

[0050] 4. Finally, the material can pass through smoothly. When shielding is required again, the push rod 22 is prompted to move outside the connection frame 12 again, and the sliding block 21 can be lowered.

[0051] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of protection required by the present invention. The scope of protection required by the present invention is defined by the appended claims and their equivalents.
