Description

Technical Field

[0001] The present application relates to the technical field of storage equipment, and in particular to a liftable blocking mechanism. Background Art

[0002] The electric blocking mechanism is used to be arranged on the tipping conveyor or the end of the conveyor to convey the conveyed articles.

[0003] The existing electric blocking mechanism is driven by a three-phase motor to control the rise and fall of the baffle. When it rises, it is used to block the goods on the conveyor belt to prevent them from falling. When it falls, it allows the goods to pass through to facilitate unloading.

[0004] However, the existing electric blocking mechanism is prone to inaccurate positioning during the rising and falling process, causing the baffle to get stuck, resulting in the baffle not being able to work normally, thereby reducing the reliability of the electric blocking mechanism. Utility Model Content

[0005] In response to the above-mentioned defects, the present application provides a liftable blocking mechanism, which can prevent the blocking plate from getting stuck when moving up and down, thereby improving the working reliability of the blocking plate.

[0006] The technical solution adopted by this application to solve the above technical problems is:

[0007] A liftable blocking mechanism comprises: at least two rotation limiters are arranged on both sides of a blocking plate, and the blocking plate is located between the two rotation limiters on the same side; the rotation limiter is arranged on a mounting seat and its rotating surface contacts the surface of the blocking plate; the blocking plate is lifted and lowered under the drive of a driving component.

[0008] Preferably, the blocking plate is connected to the driving assembly via a crank and is lifted and lowered by the driving assembly.

[0009] Preferably, a mounting hole is provided on the blocking plate, one end of the crank is connected to the output shaft of the driving assembly, and the other end is arranged in the mounting hole.

[0010] Preferably, one end of the crank disposed in the mounting hole is a rotating structure, the inner surface of the mounting hole is smooth, and the surface of the rotating structure is in contact with the inner surface of the mounting hole.

[0011] Preferably, the rotation limiting member is fixed on the mounting seat via a shaft handle.

[0012] Preferably, at least one of the rotation limiting members is connected to the output shaft of the driving assembly, and the rotation limiting member drives the blocking plate to rise and fall when driven by the driving assembly.

[0013] Preferably, a position sensing sheet is provided on the blocking plate, and the number of the position sensing sheets is two. The two position sensing sheets are provided at different heights to correspond to different position states of the blocking plate.

[0014] Preferably, a proximity switch is provided on the mounting seat, and the proximity switch cooperates with the position sensing sheet to determine the position of the blocking plate.

[0015] Preferably, the proximity switch includes an inductive proximity switch, a capacitive proximity switch, a Hall switch or a photoelectric switch.

[0016] Preferably, the rotation limiting member comprises a bearing or a cylinder with an axis.

[0017] Beneficial effect: In the present application, the blocking plate is limited by arranging rotation limit members on both sides of the blocking plate to prevent the blocking plate from being displaced due to the collision of goods during the working process. At the same time, the blocking plate is located between the two rotation limit members on the same side. Even in the event of a slight displacement, the rotating surface of the rotating member is in contact with the surface of the blocking plate. The rotation limit member can be driven to rotate by friction during the movement of the blocking plate, thereby avoiding the blocking plate from getting stuck during the up and down movement, thereby providing working reliability.

[0023] To make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the technical scheme in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all of the embodiments. The components of the embodiments of the present application generally described and shown in the drawings here can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the application claimed for protection, but merely represents the selected embodiments of the present application. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without making creative work belong to the scope of protection of the present application.

[0024] See also Figure 1-3 The present application discloses a liftable blocking mechanism, comprising: a rotation limiter 3 arranged on both sides of a blocking plate 4 and at least two rotation limiters 3 are arranged on each side, and the blocking plate 4 is located between the two rotation limiters 3 on the same side; the rotation limiter 3 is arranged on a mounting seat 1 and its rotating surface contacts the surface of the blocking plate 4; the blocking plate 4 is lifted and lowered under the drive of a driving assembly 9.

[0025] In the present application, by setting rotation limit members 3 on both sides of the blocking plate 4, in order to realize the limiting function, it is necessary to set at least two rotation limit members 3 on the same side of the blocking plate 4. It can be imagined that in the actual application scenario, the size of the blocking plate 4 will be different. In order to further improve the stability of the limiting, the number of rotation limit members 3 can be increased according to the specific situation. When increasing the number of rotation limit members 3, at least two rotation limit members 3 are added on one side of the blocking plate 4 each time, and the two added rotation limit members 3 should also be distributed on both sides of the blocking plate 4 to realize the limiting function.

[0026] The rotation limiter 3 is a rotatable structure, and its rotating surface is in contact with the surface of the blocking plate 4. There is friction between the two. When the blocking plate 4 moves up and down, the rotation limiter 3 also rotates with it. When the blocking plate 4 is offset under the influence of external force, although the blocking plate 4 will squeeze the rotation limiter 3, since the rotation limiter 3 can rotate, it will not get stuck, thereby improving the working stability of the blocking plate 4.

[0027] In the present application, the rotation limit member 3 is fixed by the fixing plate 2 on the mounting seat 1, and of course it can also be fixed by a bracket. Of course, other fixing methods that can be thought of by technical personnel in this field without creative work also belong to the protection scope of the present application, and will not be elaborated here. In order to facilitate the understanding of the technical solution, the technical solution of setting the fixing plate 2 is explained in this application.

[0028] In order to realize the function of rotating the rotation limiter 3, the rotation limiter 3 can adopt a bearing structure, a cylinder with an axis or other structures that can realize rotation around the axis, which will not be described in detail in this application.

[0029] The blocking plate 4 is driven by the driving assembly 9 to achieve up and down lifting. The present application discloses two embodiments of the connection between the blocking plate 4 and the driving assembly 9. Other technical solutions for connecting the blocking plate 4 and the driving assembly 9 to achieve up and down lifting that can be thought of by technical personnel in this field without creative work all fall within the scope of protection of the present application. Embodiment 1

[0030] In this embodiment, the blocking plate 4 is connected to the driving assembly 9 via a crank 8 and is driven by the driving assembly 9 to move up and down.

[0031] See also Figure 3 , a schematic diagram of a crank structure is given, one end of the crank mechanism is connected to the output shaft of the driving component 9, and the driving component 9 provides power, and the other end is connected to the blocking plate 4, and the output power is transmitted from the driving component 9 to the blocking plate 4. The power output direction of the driving component 9 is circular motion, and the moving direction of the blocking plate 4 is up and down. The crank 8 can not only transmit the power of the driving component 9 to the blocking plate 4, but also change the power direction.

[0032] One end of the crank 8 connected to the blocking plate is a rotating structure. In order to fix the rotating structure, a mounting hole 7 is set on the blocking plate 4, and the rotating structure is installed in the mounting hole 7. In order to improve the smoothness of the movement of the blocking plate 4, the inner surface of the mounting hole 7 is smooth, and the surface of the rotating structure contacts the inner surface of the mounting hole 7, thereby reducing the friction during the rotation of the crank 8.

[0033] In this embodiment, the rotation limiter 3 is fixed on the mounting base 1 through an axial handle, and the axial handle vertically passes through the fixing plate 2 on the mounting base 1. The rotation limiter 3 is arranged at one end close to the blocking plate 4 and the other end is fixed by a nut. Embodiment 2

[0034] See also Figure 3 In another blocking mechanism disclosed in this embodiment, at least one rotation limiter 3 is connected to the output shaft of the driving assembly 9, and the rotation limiter 3 drives the blocking plate 4 to rise and fall under the drive of the driving assembly 9.

[0035] The output shaft of the driving assembly 9 vertically passes through the fixed plate 2 and is connected to the rotation limit member 3 at one end close to the blocking plate 4. The rotation limit members 3 on both sides of the blocking plate 4 clamp the blocking plate 4. When the output shaft of the driving assembly 9 rotates, the rotation limit member 3 is driven to rotate. Because the blocking plate 4 is clamped by the rotation limit member 3, the friction between the two increases. When the rotation limit member 3 rotates, it will drive the blocking plate 3 to move, thereby realizing the up and down movement of the blocking plate 4.

[0036] In the above two embodiments, the driving assembly 9 can be a motor or other shaft power output device.

[0037] In order to determine the position of the blocking plate 4, the blocking mechanism disclosed in the present application is further provided with a position sensing sheet 5, which is provided on the blocking plate 4. In order to ensure the accuracy of position determination, two position sensing sheets 5 are provided, and the two position sensing sheets 5 are provided at different heights to correspond to different position states of the blocking plate 4. A proximity switch 6 is also provided, and when the position sensing sheet 5 reaches the position of the proximity switch 6, a position signal can be triggered to determine the position of the blocking plate 4.

[0038] like Figure 1 As shown, the position sensing piece 5 is respectively set at a high position and a low position. When the position sensing piece 5 at the low position is close to the proximity switch 6, the position signal is triggered, the driving component 9 stops working, and the blocking plate 4 stops moving. It can be seen that the blocking plate 4 is at a high position and can realize the blocking function. When the blocking needs to be cancelled, a signal is sent to the driving component 9 to control the blocking plate 4 to move downward. When the position sensing piece 5 at the high position is close to the proximity switch 6, the position signal is triggered to determine that the blocking plate 4 is in a high position, control the driving component 9 to work, and cancel the blocking function.

[0039] In the present application, the proximity switch 6 includes an inductive proximity switch, a capacitive proximity switch, a Hall switch or a photoelectric switch, or other electronic components that can realize signal triggering.

[0040] The present application limits the blocking plate by setting a rotation limiter. When the blocking plate moves up and down, the rotation limiter rotates with it, avoiding the problem that the blocking plate is easily stuck when moving up and down, and ensuring the reliability of the blocking plate.

[0041] Of course, the present application may have many other embodiments. Without departing from the spirit and essence of the present application, technicians familiar with the field can make various corresponding changes and modifications based on the present application, but these corresponding changes and modifications should all fall within the scope of protection of the claims attached to the present application.
