Description

Technical Field

[0001] This utility model relates to the field of tank conveying technology, and more specifically, to a baffle mechanism and a conveying device having the same. Background Technology

[0002] In the milk powder production process, since milk powder cans have multiple different diameters, in order to avoid setting up a conveyor belt for each diameter can, baffles of different widths can be set on the conveyor belt, thereby forming conveying channels of different widths on the conveyor belt to achieve the conveying of milk powder cans of different diameters.

[0003] In related technologies, the baffles are fixed to the frame on which the conveyor belt is installed by bolts. When it is necessary to replace the baffles of different widths, the bolts need to be removed and installed, resulting in low baffle replacement efficiency. Utility Model Content

[0004] The main objective of this invention is to provide a baffle mechanism and a conveying device having the same, so as to solve the problem of low baffle replacement efficiency in related technologies.

[0005] To achieve the above objectives, according to one aspect of the present invention, a baffle mechanism is provided, comprising: a mounting base having a backstop portion; a baffle movably disposed on the mounting base and having a stop surface, the baffle having a first stop state and a second stop state, wherein when the baffle is in the first stop state, the baffle abuts against the backstop portion, and there is a first distance between the stop surface and the mounting base; and when the baffle is in the second stop state, there is a second distance between the baffle and the mounting base, the first distance being less than the second distance; and an operating mechanism drivingly cooperating with the baffle, the operating mechanism including a first transmission member and an operating handle, the first transmission member being movably disposed on the mounting base, a first end of the first transmission member drivingly cooperating with the baffle, and the operating handle being movably disposed at a second end of the first transmission member, wherein when the baffle is in the second stop state, the operating handle is located outside the mounting base and can be locked with the mounting base to restrict the operation handle from moving into the mounting base.

[0006] Furthermore, the operating mechanism also includes a second transmission member rotatably mounted on the mounting base. The baffle includes a plate body and a third transmission member disposed on the side of the plate body. The first transmission member is in transmission engagement with the second transmission member, and the second transmission member is in transmission engagement with the third transmission member. The first transmission member and the third transmission member move in opposite directions, so that the third transmission member drives the plate body to move.

[0007] Furthermore, the operating handle is hinged to the second end of the first transmission member, and the hinge axis of the operating handle is perpendicular to the moving direction of the first transmission member. When the baffle is in the second stop state, the operating handle can rotate so that the side of the operating handle engages with the stop of the mounting seat.

[0008] Furthermore, the first transmission component includes a first rack, the second transmission component includes a gear, and the third transmission component includes a second rack. The first rack and the second rack are located on both sides of the gear and both mesh with the gear.

[0009] Furthermore, the mounting base is provided with an installation space and a clearance opening. The clearance opening is connected to the outer surface of the mounting base. The first ends of the first transmission component, the second transmission component, and the third transmission component are all located within the installation space. The second end of the third transmission component is connected to the plate and located outside the mounting base. The clearance opening is used to avoid the third transmission component.

[0010] Furthermore, the mounting base includes a base body and a cover body, with the mounting space located on the base body and the cover body located on the base body, sealing off the mounting space.

[0011] Furthermore, the baffle mechanism also includes a guide structure, which includes a guide plate and a guide groove. The guide plate is disposed in the guide groove, one of the guide plate and the guide groove is disposed on the first transmission member, and the other of the guide plate and the guide groove is disposed on the mounting base.

[0012] Furthermore, there are multiple first transmission components, multiple second transmission components, and multiple third transmission components, with each component corresponding to the others.

[0013] Furthermore, the first transmission component is provided with a first mounting hole, the operating handle is provided with a second mounting hole, and the baffle mechanism also includes a connecting shaft, which passes through the first mounting hole and the second mounting hole, and the operating handle is rotatably arranged around the axis of the connecting shaft.

[0014] According to another aspect of the present invention, a conveying device is provided, including a conveying member and a baffle mechanism disposed on the side of the conveying member, wherein the baffle mechanism is the baffle mechanism described above.

[0015] The baffle mechanism of this utility model includes a mounting base, a baffle, and an operating mechanism. By moving the operating handle, the first transmission component moves, which in turn moves the baffle. This allows the baffle to switch between a first stop state and a second stop state, meaning the distance between the baffle's stop surface and the mounting base can be changed. Thus, the operating mechanism and the mounting base enable the change of the baffle's position, avoiding the low efficiency of baffle replacement caused by disassembling bolts during replacement in existing technologies. The operating handle is movably configured so that when the baffle is in the second stop state, the handle can be adjusted to lock into the mounting base, restricting its movement inward and preventing the stop surface from being pushed towards the mounting base when the conveying component contacts the baffle, thus ensuring a more stable relative position between the baffle and the mounting base. When the baffle is in the first stop state, it abuts against the stop portion, further preventing the stop surface from being pushed towards the mounting base when the conveying component contacts the baffle, thus ensuring a more stable relative position between the baffle and the mounting base. Therefore, the technical solution of this application effectively solves the problem of the baffle being unable to move in the related technology. Attached Figure Description

It should be noted that similar reference numerals and letters in the following drawings denote similar items; therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings.

[0026] like Figures 1 to 4As shown, in this embodiment, the baffle mechanism includes: a mounting base 10, a baffle 20, and an operating mechanism 30. The mounting base 10 is provided with a stop portion 11. The baffle 20 is movably disposed on the mounting base 10 and has a stop surface 21. The baffle 20 has a first stop state and a second stop state. When the baffle 20 is in the first stop state, the baffle 20 abuts against the stop portion 11, and there is a first distance between the stop surface 21 and the mounting base 10. When the baffle 20 is in the second stop state, there is a second distance between the baffle 20 and the mounting base 10. The first distance is less than the second distance. The operating mechanism 30 is driven to cooperate with the baffle 20. The operating mechanism 30 includes a first transmission member 31 and an operating handle 32. The first transmission member 31 is movably mounted on the mounting base 10. The first end of the first transmission member 31 is driven to cooperate with the baffle 20. The operating handle 32 is movably mounted on the second end of the first transmission member 31. When the baffle 20 is in the second stop state, the operating handle 32 is located outside the mounting base 10 and can be locked to cooperate with the mounting base 10 to restrict the operation handle 32 from moving into the mounting base 10.

[0027] The baffle mechanism of this embodiment includes a mounting base 10, a baffle 20, and an operating mechanism 30. By moving the operating handle 32, the first transmission member 31 can be moved, which in turn moves the baffle 20. This allows the baffle 20 to switch between a first stop state and a second stop state, meaning the distance between the stop surface 21 of the baffle 20 and the mounting base 10 can be changed. Thus, the position of the baffle 20 is changed through the operating mechanism 30 and the mounting base 10, avoiding the low efficiency of baffle replacement caused by disassembling and reassembling bolts during baffle replacement in the prior art. The operating handle 32 is movably configured so that when the baffle 20 is in the second stop state, the position of the operating handle 32 can be adjusted to lock into the mounting base 10. This restricts the movement of the operating handle 32 into the mounting base 10, preventing the stop surface 21 from being pushed closer to the mounting base 10 when the conveying component contacts the baffle 20, thus making the relative position of the baffle 20 and the mounting base 10 more stable. When the baffle 20 is in the first stop state, the baffle 20 abuts against the anti-reverse part 11. This prevents the stop surface 21 from being pushed towards the mounting base 10 when the conveying component contacts the baffle 20, making the relative position of the baffle 20 and the mounting base 10 more stable. Therefore, the technical solution of this embodiment effectively solves the problem of the baffle being unable to move in the related art.

[0028] It should be noted that the component to be conveyed is a tank. In the width direction of the mounting base 10, the surface of the baffle 20 on the side away from the mounting base 10 is a stop surface.

[0029] like Figure 2 and Figure 3As shown, in this embodiment, the operating mechanism 30 further includes a second transmission member 33 rotatably mounted on the mounting base 10. The baffle 20 includes a plate 22 and a third transmission member 23 disposed on the side of the plate 22. The first transmission member 31 is in transmission cooperation with the second transmission member 33, and the second transmission member 33 is in transmission cooperation with the third transmission member 23. The first transmission member 31 and the third transmission member 23 move in opposite directions, so that the third transmission member 23 drives the plate 22 to move.

[0030] It should be noted that the length of the plate 22 is greater than the length of the mounting base 10. A first clearance groove is provided on the side of the plate 22 closest to the mounting base 10. When the baffle 20 is in the first stop state, part of the structure of the mounting base 10 is located within the first clearance groove. The end of the plate 22 has a smooth transition. The third transmission component 23 is connected to the inner wall of the first clearance groove.

[0031] like Figure 2 and Figure 3 As shown, in this embodiment, the operating handle 32 is hinged to the second end of the first transmission member 31. The hinge axis of the operating handle 32 is perpendicular to the moving direction of the first transmission member 31. When the baffle 20 is in the second stop state, the operating handle 32 can rotate so that the side of the operating handle 32 engages with the stop of the mounting base 10. The operating handle 32 can rotate relative to the first transmission member 31. Therefore, when the baffle 20 is in the second stop state, the operating handle 32 can rotate until the side of the operating handle 32 engages with the stop of the mounting base 10, preventing the operating handle 32 from moving into the mounting base 10, thereby preventing the stop surface 21 of the baffle 20 from moving closer to the mounting base 10, and preventing the change in the distance between the stop surface 21 and the mounting base 10 when the baffle 20 is in the second stop state.

[0032] like Figure 2 As shown, in this embodiment, the first transmission member 31 includes a first rack 311, the second transmission member 33 includes a gear 331, and the third transmission member 23 includes a second rack 231. The first rack 311 and the second rack 231 are located on both sides of the gear 331 and both mesh with the gear 331. The gear 331 can mesh with the first rack 311 and the second rack 231, so that when the operating handle 32 moves the first rack 311, the first rack 311 can drive the gear 331 to rotate, the rotation of the gear 331 can drive the second rack 231 to move, and then the second rack 231 can drive the plate 22 to move.

[0033] In this embodiment, the first transmission member 31, the second transmission member 33, and the third transmission member 23 are arranged sequentially along the length of the mounting base 10. In other embodiments, the first transmission member 31, the second transmission member 33, and the third transmission member 23 may be arranged sequentially along the thickness of the mounting base 10.

[0034] In other embodiments, the first transmission member 31 is a first transmission rod, the second transmission member 33 is a second transmission rod, and the third transmission member 23 is a third transmission rod. Both ends of the second transmission rod are hinged to the first transmission rod and the second transmission rod.

[0035] like Figure 2 and Figure 3 As shown, in this embodiment, the mounting base 10 is provided with a mounting space 12 and a clearance opening 13. The clearance opening 13 communicates with the outer surface of the mounting base 10. The first ends of the first transmission member 31, the second transmission member 33, and the third transmission member 23 are all disposed within the mounting space 12. The second end of the third transmission member 23 is connected to the plate 22 and located outside the mounting base 10. The clearance opening 13 is used to avoid the third transmission member 23. The mounting space 12 allows the first transmission member 31, the second transmission member 33, and the third transmission member 23 to be installed inside the mounting base 10. The clearance opening 13 allows the third transmission member 23 to be avoided, allowing a portion of the third transmission member 23 to extend out of the mounting base 10.

[0036] It should be noted that the anti-retraction part 11 can be the outer surface of the mounting base 10 or the inner wall of the mounting space 12. In this embodiment, the anti-retraction part 11 is the inner wall of the mounting space 12.

[0037] It should be noted that the mounting base 10 is also provided with a receiving opening, which communicates with the outer surface of the mounting base 10 and is connected to the mounting space 12. Part of the structure of the first transmission member 31 passes through the receiving opening.

[0038] like Figure 1 and Figure 2 As shown, in this embodiment, the mounting base 10 includes a base 14 and a cover 15. An installation space 12 is disposed on the base 14, and the cover 15 is disposed on the base 14, sealing off the installation space 12. The base 14 supports the first transmission member 31, the second transmission member 33, the third transmission member 23, and the cover 15. The cover 15 seals off the installation space 12, preventing debris from entering the installation space 12 and also making the overall appearance of the baffle mechanism more aesthetically pleasing.

[0039] The base 14 is provided with a second clearance groove. When the baffle 20 is in the second stop state, part of the structure of the operating handle 32 is located in the second clearance groove.

[0040] In other embodiments, the baffle 20 also includes a flat plate located above the mounting base 10 and disposed on the plate body 22. In this case, a cover may not be provided, and the mounting space 12 can be closed by the flat plate.

[0041] like Figure 3As shown, in this embodiment, the baffle mechanism further includes a guide structure 40, which includes a guide plate 41 and a guide groove 42. The guide plate 41 is disposed within the guide groove 42 and is mounted on the first transmission member 31. The guide groove 42 is disposed on the mounting base 10. The guide plate 41 and the guide groove 42 can guide and cooperate, allowing the first transmission member 31 to slide more smoothly relative to the mounting base 10.

[0042] It should be noted that the purpose is that the guide groove 42 is a dovetail groove, and the shape of the guide plate 41 is adapted to the shape of the guide groove 42.

[0043] In other embodiments, the guide groove 42 is disposed on the first transmission member 31, and the guide plate 41 is disposed on the mounting base 10.

[0044] like Figure 2 and Figure 3 As shown, in this embodiment, there are multiple first transmission members 31, multiple second transmission members 33, and multiple third transmission members 23, and each of these multiple transmission members 31, multiple second transmission members 33, and multiple third transmission members 23 is arranged in a one-to-one correspondence. The arrangement of multiple first transmission members 31, multiple second transmission members 33, and multiple third transmission members 23 allows for smoother movement of the baffle 20 relative to the mounting base 10.

[0045] like Figure 2 As shown, in this embodiment, the first transmission member 31 is provided with a first mounting hole, the operating handle 32 is provided with a second mounting hole, and the baffle mechanism further includes a connecting shaft 50, which passes through the first and second mounting holes. The operating handle 32 is rotatably arranged around the axis of the connecting shaft 50. The connecting shaft 50 can connect the operating handle 32 and the first transmission member 31.

[0046] like Figure 4 As shown, the conveying device of this embodiment includes a conveying member 100 and a baffle mechanism disposed on the side of the conveying member 100. The baffle mechanism is the one described above. The baffle 20 of the baffle mechanism can move under the action of the operating handle 32 and the first transmission member 31, that is, the position of the baffle 20 can be changed, avoiding the problem of low baffle replacement efficiency caused by disassembling and assembling bolts when replacing the baffle in the prior art. The conveying device with the baffle mechanism described above also has the aforementioned advantages.

[0047] It should be noted that the conveying device also includes a frame, on which the conveyor component 100 is mounted. The baffle 20 is located directly above the conveyor component.

[0048] A limiting plate is provided on the frame, and a first limiting groove 16 is provided at the bottom of the mounting base 10. The limiting plate and the first limiting groove 16 are inserted into each other. The first limiting groove 16 is a T-shaped groove, and the shape of the limiting plate is adapted to the shape of the first limiting groove 16.

[0049] The baffle 20 is also provided with a second limiting groove, which corresponds to and has the same structure as the first limiting groove 16. When the baffle is in the first stop state, part of the limiting plate is located in the second limiting groove.

[0050] The conveying device also includes a fixing component that connects the mounting base 10 and the frame. Specifically, the fixing component is connected to both the mounting base and the limiting plate. The fixing component is a bolt.

[0051] The conveyor 100 includes a conveyor plate chain; of course, the conveyor 100 can also be a conveyor belt or a conveyor roller.

[0052] The width direction of the mounting base 10 is parallel to the width direction of the conveyor 100. The length direction of the mounting base 10 is parallel to the length direction of the conveyor 100. The hinge axis of the operating handle 32 is parallel to the length direction of the mounting base 10. The moving directions of the third transmission member 23 and the baffle 20 are both parallel to the width direction of the mounting base 10. The thickness direction of the mounting base 10 is perpendicular to both the width and length directions of the conveyor 100. The length direction of the conveyor 100 is the running direction of the conveyor chain.

[0053] It should be noted that in this embodiment, there are multiple baffle mechanisms, which are arranged sequentially along the length of the conveying member 100. The interval between the two baffles 20 of two adjacent baffle mechanisms is smaller than the diameter of the tank, which can prevent the tank from getting stuck between the two baffles 20 and causing the tank to jam.

[0054] Of course, in other embodiments, a baffle mechanism may be included, in which case the length direction of the baffle 20 is greater than or equal to the distance between the inlet end and the outlet end of the conveyor 100, ensuring smooth movement of the tank on the conveyor 100.

[0055] In this embodiment, when the conveying device is in use, the baffle mechanism is installed on the frame, and then the operating handle 32 is pushed into the mounting base 10. The operating handle 32 drives the first transmission member 31 to move into the mounting base 10, and then the mounting base 10 drives the second transmission member 33 to rotate. The second transmission member 33 drives the third transmission member 23 to move into the mounting base 10, and the third transmission member 23 drives the plate 22 to move into the mounting base 10. The plate 22 moves toward the mounting base 10 until the baffle 20 abuts against the stop part 11, and the baffle 20 is in the first stop state. When the baffle 20 switches from the first stop state to the second stop state, the operating handle 32 is pulled outward from the mounting base 10. The operating handle 32 drives the second transmission component 33 to rotate, and the second transmission component 33 drives the third transmission component 23 to move outward from the mounting base 10. The third transmission component 23 drives the plate 22 away from the mounting base 10, and the baffle 20 switches to the second stop state. Then, the operating handle 32 is rotated downward, and the side of the operating handle 32 is locked with the mounting base 10 to prevent the operating handle 32 from moving inward from the mounting base 10, that is, to prevent the baffle 20 from moving towards the mounting base 10.

[0056] A baffle mechanism is disposed on the first side of the conveyor 100, forming a conveying channel between the baffle 20, the second side of the conveyor 100, and the top of the conveyor 100. The first side and the second side of the conveyor 100 are disposed opposite to each other. When the baffle 20 is in the first stop state, the width of the conveying channel is a first width; when the baffle 20 is in the second stop state, the width of the conveying channel is a second width. The first width is greater than the second width, thus enabling the conveying of tanks of different diameters.

[0057] In the description of this utility model, it should be understood that "multiple" means two or more. Directional terms such as "front, back, up, down, left, right," "horizontal, vertical, perpendicular, horizontal," and "top, bottom" indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings. These terms are used solely for the convenience of describing this utility model and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as limiting the scope of protection of this utility model. The directional terms "inner" and "outer" refer to the inner or outer contours relative to the outline of each component itself.

[0058] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0059] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be construed as limiting the scope of protection of this utility model.

[0060] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. 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.
