Description

Technical Field

[0001] This application relates to the field of conveying and transfer technology, and in particular to a conveyor plate mechanism. Background Technology

[0002] In a related technical field, a conveyor belt for transporting cigarette boxes is equipped with a conveyor plate mechanism. The pusher plate on the conveyor plate mechanism pushes the cigarette boxes to move along the conveyor belt, thereby realizing the transport of cigarette boxes.

[0003] The conveyor plate mechanism is prone to deformation or breakage due to overload during the transfer process. Furthermore, the limited working space makes disassembly and installation of the conveyor plate mechanism inconvenient during maintenance and replacement, increasing the difficulty and time required for maintenance. Utility Model Content

[0004] Therefore, it is necessary to provide a conveyor plate mechanism that can be quickly disassembled and installed to address the aforementioned technical problems.

[0005] An embodiment of the first aspect of this application provides a conveyor plate mechanism, including a first connector, a second connector, and an elastic member. The first connector has a connecting groove extending along a first direction. The second connector is detachably connected to the first connector and has a connecting block that matches the connecting groove. The elastic member is connected to either the first connector or the second connector and has a compressed state and a springback state. When the elastic member is in the compressed state, the connecting block can move within the connecting groove along the first direction to separate the first connector from the second connector. When the first connector is connected to the second connector, at least a portion of the connecting block extends into the connecting groove, and the elastic member is in the springback state to restrict the movement of the connecting block within the connecting groove. A push plate is provided on one of the first connector and the second connector.

[0006] In one embodiment, the elastic member is connected to the second connector; the first connector is also provided with a limiting groove extending in the second direction, the limiting groove is connected to the connecting groove, and the first direction intersects the second direction; when the first connector is connected to the second connector, the elastic member extends at least partially into the limiting groove, and the sidewall of the limiting groove restricts the movement of the elastic member in the first direction; when the elastic member is in a compressed state, the elastic member is located outside the limiting groove.

[0007] In one embodiment, the first connector is further provided with a first surface, and the connecting groove and the limiting groove are both recessed on the first surface; the second connector is further provided with a second surface, and the connecting block is protruding on the second surface; when the first connector and the second connector are connected, the first surface and the second surface are arranged parallel to each other.

[0008] In one embodiment, when the first connector is connected to the second connector, the first surface and the second surface are arranged parallel to each other along a third direction, and the first direction, the second direction and the third direction are arranged to intersect each other.

[0009] In one embodiment, a relief groove is also recessed on the second surface. When the elastic member is in a compressed state, at least a portion of the elastic member extends into the relief groove, and when the elastic member is in a rebound state, at least a portion of the elastic member is outside the relief groove.

[0010] In one embodiment, the clearance groove includes two clearance grooves, which are located on both sides of the connecting block in the second direction, and both clearance grooves extend along the second direction.

[0011] In one embodiment, the elastic member includes a connecting portion and two elastic portions located on both sides of the connecting portion in a second direction. The connecting portion is connected to a second connecting member. When the first connecting member is connected to the second connecting member, at least a portion of at least one elastic portion extends into a limiting groove, and the sidewall of the limiting groove restricts the movement of the elastic portion along the first direction. When the elastic member is in a compressed state, the two elastic portions extend into two clearance grooves respectively.

[0012] In one embodiment, the connecting block is provided with a receiving groove that extends through the connecting block in a second direction, the connecting part is located inside the receiving groove, and at least part of the elastic part extends out of the receiving groove.

[0013] In one embodiment, the connecting portion has a third surface on the side opposite to the second surface, and the connecting block has a fourth surface on the side opposite to the second surface; the third surface and the fourth surface are flush, or the distance between the third surface and the second surface is less than the distance between the fourth surface and the second surface.

[0014] In one embodiment, the connecting groove is a dovetail groove or a T-shaped groove.

[0015] The conveyor plate mechanism provided in this application includes a push plate on one of the first and second connecting members for pushing the cigarette box. By providing a connecting groove on the first connecting member and a connecting block matching the connecting groove on the second connecting member, the first and second connecting members can be moved and connected in a first direction. By providing an elastic member connected to either the first or second connecting member, the elastic member restricts the movement of the first and second connecting members in the first direction when in a rebound state, thus achieving connection between the first and second connecting members. When the elastic member is compressed, it unlocks the first and second connecting members, allowing them to separate along the first direction. This enables the user to quickly disassemble and install the first and second connecting members by operating the elastic member, reducing maintenance difficulty and time.

[0030] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0031] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and 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 a limitation of this application.

[0032] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0033] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0034] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0035] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0036] The conveyor plate mechanism provided in the embodiments of this application will now be described with reference to the accompanying drawings. In the drawings, for ease of drawing, the dimensions shown are not necessarily proportional to the actual dimensions.

[0037] Please refer to Figures 1 to 5 , Figure 1 This is a schematic diagram of the structure of the conveyor plate mechanism in some embodiments of this application. Figure 2 A side view of an example conveyor plate mechanism is shown. Figure 3 A front view schematic diagram of an example conveyor plate mechanism is shown. Figure 4 A schematic diagram of the structure of a first connector is shown as an example. Figure 5 A schematic diagram of the structure of an example second connector and elastic member is shown.

[0038] like Figures 1 to 5As shown, this application provides a conveyor plate mechanism 10, including a first connector 100, a second connector 200, and an elastic member 300. The first connector 100 has a connecting groove 110 extending along a first direction (x direction in the figure). The second connector 200 is detachably connected to the first connector 100, and the second connector 200 has a connecting block 210 that matches the connecting groove 110. The elastic member 300 is connected to either the first connector 100 or the second connector 200, and the elastic member 300 has a compressed state and a springback state. When the elastic member 300 is in the compressed state, the connecting block 210 can move within the connecting groove 110 along the first direction x, so that the first connector and the second connector are separated. When the first connector 100 is connected to the second connector 200, at least a portion of the connecting block 210 extends into the connecting groove 110, and the elastic member 300 is in the springback state to restrict the movement of the connecting block 210 within the connecting groove 110. A push plate 400 is provided on one of the first connector 100 and the second connector 200.

[0039] Optionally, when the elastic element 300 is not subjected to external force, it is in a spring-back state. When the elastic element 300 is subjected to external force, it switches from the spring-back state to the compression state. After the external force disappears, the elastic element 300 automatically changes back from the compression state to the spring-back state.

[0040] Optionally, one of the first connecting member 100 and the second connecting member 200 is provided with a push plate 400, and the other is installed on a conveyor belt (not shown) for transferring cigarette boxes. This embodiment illustrates the example with the push plate 400 located on the first connecting member 100 and the second connecting member 200 connected to the conveyor belt. The push plate 400 is located on one side of the first connecting member 100 in the first direction x. When the second connecting member 200 is installed on the conveyor belt and the first connecting member 100 is connected to the second connecting member 200, the conveyor belt drives the conveyor plate mechanism 10 to move along the first direction x, and the push plate 400 pushes the cigarette boxes located on the conveyor belt to move synchronously along the first direction x. At this time, since the elastic member 300 is in a rebound state, the elastic member 300 restricts the relative movement of the first connecting member 100 and the second connecting member 200 along the first direction x, thus realizing the connection between the first connecting member 100 and the second connecting member 200. When the conveyor plate mechanism 10 needs to be replaced or repaired, the user can directly control the elastic element 300 to switch from the spring-loaded state to the compressed state. At this time, the first connector 100 and the second connector 200 are unlocked, and the connecting block 210 can move within the connecting groove 110, allowing the first connector 100 to move along the first direction x until the connecting block 210 exits the connecting groove 110. At this time, the first connector 100 and the second connector 200 are separated, and the user can directly replace or repair the first connector 100 and the push plate 400 as needed, without having to remove the second connector 200 from the conveyor belt, reducing the difficulty and time required for repairs. When the user wants to install the first connector 100, he also manipulates the elastic element 300 to switch it from the spring state to the compressed state. Then, the connecting block 210 is inserted into the connecting groove 110 along the first direction x, and the first connector 100 is moved along the first direction x until the first connector 100 and the second connector 200 are installed in place. Then, the user releases the elastic element 300 so that the compressed state automatically changes back to the spring state and locks the first connector 100 and the second connector 200.

[0041] Of course, in other embodiments, the pusher plate 400 may also be located on the second connector 200, with the first connector 100 connected to the conveyor belt. The installation and disassembly process can be referenced in the above scenario and will not be repeated here.

[0042] Optionally, when the first connector 100 and the second connector 200 are installed in place, the connecting block 210 is completely located within the connecting groove 110.

[0043] Optionally, the second connector 200 is bolted to the conveyor belt.

[0044] The conveyor plate mechanism 10 of this application embodiment has a push plate 400 on one of the first connecting member 100 and the second connecting member 200 for pushing the cigarette box, and the other is connected to the conveyor belt. This makes the conveyor plate mechanism 10 a split design, reducing the probability of the force being transmitted to the conveyor plate when the push plate 400 is overloaded, thereby reducing the probability of damage to the conveyor plate. At the same time, when repairing and replacing the first conveyor plate mechanism 10, only the first connecting member 100 and the push plate 400 need to be repaired and replaced, without removing the second connecting member 200, reducing maintenance costs, repair difficulty and repair time. By providing a connecting groove 110 on the first connecting member 100 and a connecting block 210 matching the connecting groove 110 on the second connecting member 200, the first connecting member 100 and the second connecting member 200 can be moved and connected in the first direction x. By providing an elastic element 300 connected to either the first connector 100 or the second connector 200, the elastic element 300 restricts the movement of the first connector 100 and the second connector 200 in the first direction x when in the rebound state, thereby achieving the connection between the first connector 100 and the second connector 200. When the elastic element 300 is in the compressed state, the first connector 100 and the second connector 200 are unlocked, and the first connector 100 and the second connector 200 can be separated along the first direction x. This allows the user to quickly disassemble and install the first connector 100 and the second connector 200 by operating the elastic element 300, further reducing maintenance difficulty and time.

[0045] In some embodiments, the connecting groove 110 is a dovetail groove or a T-shaped groove.

[0046] Optionally, in this embodiment, the connecting groove 110 is described as a dovetail groove. When the connecting block 210 extends into the connecting groove 110, the first connecting member 100 and the second connecting member 200 are arranged parallel to each other along the third direction (the z-direction in the figure). Due to the shape limitation of the dovetail groove, when the connecting block 210 extends into the connecting groove 110, the connecting groove 110 restricts the connecting block 210 from moving in the second direction (the y-direction in the figure) and the third direction z. The first direction x, the second direction y, and the third direction z are arranged in pairs, which can be understood as the first direction x being the direction of movement of the conveyor belt, i.e., the front-back direction; the second direction y being the left-right direction; and the third direction z being the up-down direction. The setting of the connecting groove 110 ensures that the connecting block 210 can only move in the front-back direction within the connecting groove 110, and cannot move in the up-down or left-right directions. Furthermore, the setting of the elastic member 300 further restricts the connecting block 210 from moving in the front-back direction within the connecting groove 110, thereby achieving the connection between the first connecting member 100 and the second connecting member 200.

[0047] When the connecting slot 110 is a T-shaped slot, it can also fulfill the same function. Of course, the connecting slot 110 can also be other irregular slots that can achieve upper limit positioning in the second direction y and the third direction z, which will not be elaborated here.

[0048] The conveyor plate mechanism 10 of this application embodiment enables the connecting block 210 to move within the connecting groove 110 along the first direction x by making the connecting groove 110 a dovetail groove or a T-shaped groove. The connecting groove 110 limits the connecting block 210 in the second direction y and the third direction z, thereby realizing the quick disassembly and installation of the first connecting member 100 and the second connecting member 200.

[0049] In some embodiments, the elastic member 300 is connected to the second connector 200. The first connector 100 is also provided with a limiting groove 120 extending along the second direction y, and the limiting groove 120 communicates with the connecting groove 110. When the first connector 100 is connected to the second connector 200, the elastic member 300 extends at least partially into the limiting groove 120, and the sidewall of the limiting groove 120 restricts the movement of the elastic member 300 along the first direction x. When the elastic member 300 is in a compressed state, the elastic member 300 is located outside the limiting groove 120.

[0050] Optionally, both the connecting groove 110 and the limiting groove 120 extend through the first connecting member 100. The shape of the limiting groove 120 matches the shape of the elastic member 300.

[0051] Optionally, the first connector 100 is further provided with a first surface 130, and both the connecting groove 110 and the limiting groove 120 are recessed in the first surface 130. The second connector 200 is further provided with a second surface 220, and the connecting block 210 protrudes from the second surface 220. When the first connector 100 and the second connector 200 are connected, the first surface 130 and the second surface 220 are arranged parallel to each other.

[0052] Optionally, when the first connector 100 is connected to the second connector 200, the first surface 130 and the second surface 220 are arranged parallel to each other along the third direction z.

[0053] The limiting groove 120 is used to cooperate with the elastic member 300. The elastic member 300 and the limiting groove 120 are located on the second connector 200 and the first connector 100, respectively. When the elastic member 300 extends into the limiting groove 120, since the limiting groove 120 extends along the second direction y, which intersects with the first direction x, the sidewall of the limiting groove 120 restricts the movement of the elastic member 300 along the first direction x. Consequently, the first connector 100 and the second connector 200 mutually limit each other in the first direction x, realizing the connection function of the first connector 100 and the second connector 200. Until the elastic member 300 switches from the spring state to the compressed state, the elastic member 300 exits the limiting groove 120. After losing the mutual limiting function between the elastic member 300 and the limiting groove 120, the first connector 100 and the second connector 200 regain their freedom in the first direction x.

[0054] Of course, in other embodiments, the elastic element 300 may also be connected to the first connector 100, and the limiting groove 120 may be disposed on the second connector 200.

[0055] The conveyor plate mechanism 10 of this application embodiment, by positioning the elastic member 300 and the limiting groove 120 on the second connector 200 and the first connector 100 respectively, enables the elastic member 300 to lock or unlock the first connector 100 and the second connector 200 in the first direction x when switching between the rebound state and the compression state.

[0056] Please refer to Figure 1-2 , Figure 5-6 , Figure 6 A side view of an example of a second connector and an elastic member is shown.

[0057] like Figure 1-2 , Figure 5-6 As shown, in some embodiments, a relief groove 230 is also recessed on the second surface 220. When the elastic member 300 is in a compressed state, at least a portion of the elastic member 300 extends into the relief groove 230. When the elastic member 300 is in a rebound state, at least a portion of the elastic member 300 is outside the relief groove 230.

[0058] Optionally, the clearance groove 230 includes two grooves, which are located on both sides of the connecting block 210 in the second direction y, and both grooves extend along the second direction y. The two clearance grooves 230 are not connected, that is, the clearance grooves 230 do not pass through the second connecting member 200.

[0059] Optionally, the elastic member 300 includes a connecting portion 310 and two elastic portions 320 located on both sides of the connecting portion 310 in the second direction y. The connecting portion 310 is connected to the second connecting member 200. When the first connecting member 100 is connected to the second connecting member 200, at least a portion of at least one elastic portion 320 extends into the limiting groove 120, and the sidewall of the limiting groove 120 restricts the movement of the elastic portion 320 along the first direction x. When the elastic member 300 is in a compressed state, the two elastic portions 320 respectively extend into the two clearance grooves 230.

[0060] The elastic element 300 is preferably a leaf spring. The connecting portion 310 located in the middle of the elastic element 300 is bolted to the second connecting member 200, and the two elastic portions 320 located on both sides of the elastic element 300 are suspended. This allows the elastic element 300 to be in a compressed state when the elastic portion 320 is pressed down by an external force, and the elastic element 300 to tend to return to a spring-like state where the elastic portion 320 is flush with the connecting portion 310 when the external force on the elastic portion 320 disappears.

[0061] Optionally, when the first connector 100 and the second connector 200 are connected, the limiting groove 120 and the clearance groove 230 are connected, and the side wall of the limiting groove 120 is flush with the side wall of the clearance groove 230, and the elastic part 320 can undergo elastic deformation in the limiting groove 120 and the clearance groove 230.

[0062] The conveyor plate mechanism 10 of this application embodiment uses a leaf spring for the elastic member 300 and provides a relief groove 230 on the second surface 220 to cooperate with the elastic member 300. When the elastic part 320 is in the rebound state, it extends into the limiting groove 120 to lock the first connector 100 and the second connector 200 in the first direction x. When the elastic part 320 is in the compressed state, it exits the limiting groove 120 and enters the relief groove 230. The elastic part 320 located in the relief groove 230 will not interfere with the movement of the first connector 100 relative to the second connector 200 in the first direction x, thereby unlocking the first connector 100 and the second connector 200.

[0063] like Figure 5-6 As shown, in some embodiments, the connecting block 210 is provided with a receiving groove 211 extending through the connecting block 210 in the second direction y, the connecting part 310 is located inside the receiving groove 211, and at least part of the elastic part 320 extends out of the receiving groove 211.

[0064] Optionally, the connecting portion 310 has a third surface 311 on the side opposite to the second surface 220, and the connecting block 210 has a fourth surface 212 on the side opposite to the second surface 220. The third surface 311 and the fourth surface 212 are flush, or the distance between the third surface 311 and the second surface 220 is less than the distance between the fourth surface 212 and the second surface 220. It can be understood that the third surface 311 is the upper surface of the connecting portion 310, and the fourth surface 212 is the upper surface of the connecting block 210.

[0065] The conveyor plate mechanism 10 of this application provides a receiving groove 211 for accommodating the connecting part 310 on the connecting block 210, and makes the upper surface of the connecting part 310 flush with or lower than the upper surface of the connecting block 210, so that the connecting part 310 does not interfere with the movement of the connecting block 210 within the connecting groove 110.

[0066] When the user wants to install the first connector 100, first press the elastic portions 320 on both sides so that the elastic portions 320 are in the clearance groove 230, at which point the elastic member 300 is in a compressed state. Next, align the connecting groove 110 with the connecting block 210, and extend the connecting block 210 into the connecting groove 110 along the first direction x until the limiting groove 120 and the clearance groove 230 are connected. Then, the user releases the elastic portions 320. The elastic member 300 switches to a spring-back state, allowing the elastic portions 320 to extend from the clearance groove 230 into the limiting groove 120, thus locking the first connector 100 and the second connector 200. When it is necessary to remove the first connector 100, similarly, first press the elastic portions 320 on both sides so that the elastic portions 320 are in the clearance groove 230, and then remove the first connector 100 along the first direction x.

[0067] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of this patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this application should be determined by the appended claims.
