Description

Technical Field

[0001] This utility model relates to the field of transfer equipment technology, and in particular to a two-stage telescopic mechanism. Background Technology

[0002] During the maintenance of cigarette production equipment, it is common to modify the packaging equipment according to actual process needs. In such cases, mechanical devices are required to perform precise transfer of the cigarette packs.

[0003] However, existing transfer devices of this type have low space utilization and large size. When applied to special cases with very strict space requirements, the installation space is obviously insufficient and cannot be used in the modification process. Utility Model Content

[0004] The purpose of this invention is to provide a two-stage telescopic mechanism to simplify the specific structure, reduce the space occupied, and achieve precise transfer of products to be processed.

[0005] To achieve this objective, the present invention adopts the following technical solution:

The fixed frame includes two first male connectors. The first lifting frame includes a first frame plate, one surface of which is fixed with two first female connectors, and the other surface of which is fixed with two second male connectors. Each first female connector is slidably engaged with one of the first male connectors. The second lifting frame includes a second frame plate, one surface of which is fixed with two second female connectors. Each second female connector is slidably engaged with one of the second male connectors. A material tray for supporting the products to be processed is fixed to the top of the second frame plate, and a clearance groove is formed through the bottom of the second frame plate. The two second female connectors are located on opposite sides of the clearance groove. One drive unit is fixed to the fixed frame and located between the two first male connectors, for driving the first lifting frame to move relative to the fixed frame. The other drive unit is fixed to the first lifting frame and at least partially extends through the clearance groove, for driving the second lifting frame to move relative to the first lifting frame.

[0007] As an optional technical solution for the secondary telescopic mechanism, the fixed frame includes a base platform and two support frames, and the drive unit and the support frames are both fixedly connected to the base platform.

[0009] As an optional technical solution for the two-stage telescopic mechanism, the first lifting frame can move vertically relative to the fixed frame, the second lifting frame can move vertically relative to the first lifting frame, and the top of the material tray is provided with a placement surface, which is perpendicular to the vertical direction.

[0010] As an optional technical solution for the secondary telescopic mechanism, a number of limiting blocks are fixedly connected to the top of the material tray. The multiple limiting blocks are used to restrict the movement of the product to be processed within the placement surface from at least two different directions that are not on the same straight line.

[0011] As an optional technical solution for the secondary telescopic mechanism, the drive unit includes a cylinder body and a flow rate regulator and a sensor disposed on the cylinder body. The flow rate regulator is used to adjust the speed of the action of the actuator end of the cylinder body, and the sensor is used to sense the position of the actuator end of the cylinder body.

[0012] As an optional technical solution for the secondary telescopic mechanism, a first floating joint is fixedly connected to the plate surface of the first frame plate where the first female connector is provided. The first floating joint is used to connect to the actuating end of one of the cylinder bodies. A second floating joint is fixedly connected to the bottom of the material tray. The second floating joint is used to connect to the actuating end of another cylinder body.

[0013] As an optional technical solution for the secondary telescopic mechanism, the second floating joint and the second female connector are located on opposite sides of the second frame plate.

[0014] As an optional technical solution for the secondary telescopic mechanism, one of the first male connector and the first female connector is a first guide block and the other is a first linear guide rail. The first linear guide rail can move relative to the first guide block along the length direction of the first linear guide rail.

[0015] As an optional technical solution for the secondary telescopic mechanism, one of the second male connector and the second female connector is a second guide block and the other is a second linear guide rail.

[0016] The beneficial effects of this utility model are:

[0017] This two-stage telescopic mechanism achieves two-stage telescopic movement through the combination of two drive units, ensuring the accuracy of position adjustment for the products being processed. Simultaneously, the sliding cooperation of the female and male connectors ensures smooth relative movement between the fixed frame and the first lifting frame, as well as between the first and second lifting frames, preventing deviations from the predetermined trajectory and increasing operational stability. The material tray provides effective support, ensuring efficient transfer of the products. The design of the first female and second male connectors positioned on opposite sides of the first frame plate, and the second female connector positioned on opposite sides of the clearance slot, optimizes the structural layout of the first and second lifting frames. Combined with a drive unit positioned between the two first male connectors and another drive unit at least partially extending through the clearance slot, the placement of the two drive units is rationally planned, simplifying the specific structure of the two-stage telescopic mechanism and reducing space requirements. The cooperation between the fixed frame, the first and second lifting frames, and the power provided by the drive units facilitates automation of the entire transfer process, contributing to improved work efficiency. Meanwhile, the two-stage telescopic mechanism is stable in connection and moves smoothly, improving the efficiency and safety of transportation. It can also be adjusted for extension and retraction according to actual needs, enabling it to adapt to various different transportation needs of products to be processed, thereby expanding its application scope.

[0034] like Figures 1 to 6 As shown, this embodiment provides a two-stage telescopic mechanism for transferring the product 500 to be processed. The two-stage telescopic mechanism includes a fixed frame 400, a first lifting frame 200, a second lifting frame 300, and two drive units 100. The fixed frame 400 includes two first male connectors. The first lifting frame 200 includes a first frame plate 230, one surface of which is fixedly provided with two first female connectors, and the other surface of which is fixedly provided with two second male connectors. Each first female connector is slidably engaged with one first male connector. The second lifting frame 300 includes a second frame plate, one surface of which is fixedly provided with two second male connectors. Each second female connector is slidably engaged with a second male connector. A material tray 310 for supporting the product 500 to be processed is fixedly connected to the top of the second frame plate. A clearance groove is passed through the bottom of the second frame plate. Two second female connectors are located on both sides of the clearance groove. A drive unit 100 is fixedly connected to the fixed frame 400 and located between the two first male connectors for driving the first lifting frame 200 to move relative to the fixed frame 400. Another drive unit 100 is fixedly connected to the first lifting frame 200 and at least partially passes through the clearance groove for driving the second lifting frame 300 to move relative to the first lifting frame 200.

[0035] This two-stage telescopic mechanism achieves two-stage telescopic movement through the combination of two drive units 100, ensuring the accuracy of position adjustment for the product 500 to be processed. Simultaneously, the sliding engagement of the female and male connectors ensures smooth relative movement between the fixed frame 400 and the first lifting frame 200, and between the first lifting frame 200 and the second lifting frame 300, preventing deviation from the predetermined trajectory and thus increasing operational stability. The material tray 310 provides effective support, ensuring efficient transfer of the product 500 to be processed. The design of the first female connector and the second male connector, respectively located on both sides of the first frame plate 230, and the second female connector positioned on both sides of the clearance slot, shapes the structural layout of the first lifting frame 200 and the second lifting frame 300. Combined with the design of one drive unit 100 positioned between the two first male connectors and another drive unit 100 at least partially extending through the clearance slot, the placement of the two drive units 100 can be rationally planned, thus simplifying the specific structure of the secondary telescopic mechanism and reducing the space occupied. Through the cooperation of the fixed frame 400, the first lifting frame 200, and the second lifting frame 300, and the power supply of the drive unit 100, the entire transfer process can be automated, improving work efficiency. Simultaneously, the secondary telescopic mechanism offers stable connection and smooth movement, improving transfer efficiency and safety. Furthermore, it can be adjusted for extension and retraction according to actual needs, allowing the secondary telescopic mechanism to adapt to the transfer requirements of various products 500 to be processed, thereby expanding its application range.

[0036] In this embodiment, the fixed frame 400 includes a base platform 430 and two support frames 410, and the drive unit 100 and the support frames 410 are both fixedly connected to the base platform 430.

[0037] By designing a fixed frame 400 including a base platform 430 and two support frames 410, the drive unit 100 and the support frames 410 are both fixed to the base platform 430, enhancing the stability of the entire secondary telescopic mechanism. This design makes the secondary telescopic mechanism more stable and smoother during operation, reducing vibration and damage to the product 500 during transport. It also simplifies the specific structure of the secondary telescopic mechanism and improves the convenience of transport.

[0038] For example, a drive unit 100 is fixedly connected to the first frame plate 230 on the plate surface where the second male connector is provided, and the drive unit 100 is located between the two second male connectors.

[0039] By arranging the drive unit 100 between the two second male connectors, the drive unit 100 can more effectively control the movement of the first lifting frame 200, thereby improving the control accuracy and stability of the secondary telescopic mechanism, simplifying the structural layout of the first lifting frame 200, and further reducing the space occupied by the secondary telescopic mechanism.

[0040] In this embodiment, the first lifting frame 200 can move vertically relative to the fixed frame 400, the second lifting frame 300 can move vertically relative to the first lifting frame 200, and the top of the material tray 310 is provided with a placement surface, which is perpendicular to the vertical direction.

[0041] The dual telescopic design of the first lifting frame 200 and the second lifting frame 300, which move vertically, allows the secondary telescopic mechanism to adapt to products 500 at different heights. Simultaneously, the top of the material tray 310 has a vertically perpendicular placement surface, providing stable support for the product 500 and reducing the risk of accidental displacement. This optimizes the spatial layout of the secondary telescopic mechanism, simplifies its structure, and reduces the space it occupies.

[0042] Furthermore, a number of limiting blocks 320 are fixed to the top of the material tray 310. The multiple limiting blocks 320 are used to restrict the movement of the product to be processed 500 within the placement surface from at least two different directions that are not on the same straight line.

[0043] The aforementioned limiting block 320 can restrict the movement of the product to be processed 500 within the placement surface from different directions, ensuring the stability of the product to be processed 500 during the transfer process and reducing the risk of the product to be processed 500 shifting or falling.

[0044] In this embodiment, the drive unit 100 includes a cylinder body 110, a flow rate regulator 120 and a sensor 130 disposed on the cylinder body 110. The flow rate regulator 120 is used to adjust the speed of the action of the actuator of the cylinder body 110, and the sensor 130 is used to sense the position of the actuator of the cylinder body 110.

[0045] The speed regulator 120 and sensor 130 enable the secondary telescopic mechanism to have precise control capabilities. During transport, the speed of the actuator can be adjusted according to actual conditions, and the relative positional relationship can be accurately grasped, thereby improving the working accuracy and efficiency of the secondary telescopic mechanism. Sensor 130 is used to sense the position of the actuator of the cylinder body 110, contributing to the improvement of intelligent control of the secondary telescopic mechanism.

[0046] Furthermore, a first floating joint 220 is fixedly connected to the surface of the first frame plate 230 where the first female connector is located. The first floating joint 220 is used to connect the actuating end of one cylinder body 110. A second floating joint 340 is fixedly connected to the bottom of the material tray 310. The second floating joint 340 is used to connect the actuating end of another cylinder body 110. Specifically, the cylinder body 110 is a thin cylinder.

[0047] The floating joint ensures a stable connection to the actuator of the drive unit 100, thereby enhancing stability and reliability during transport and reducing operational errors caused by positional deviations of the product 500.

[0048] Furthermore, the second floating joint 340 and the second female connector are located on opposite sides of the second frame plate.

[0049] By selecting the placement position of the second floating joint 340, the structural layout of the second lifting frame 300 is simplified. While ensuring the transmission effect of the drive unit 100 to the second lifting frame 300, the structure of the secondary telescopic mechanism is made more compact and the operation more flexible. The above design also makes the secondary telescopic mechanism more balanced during operation, reduces errors caused by its own weight, and improves the accuracy of transportation.

[0050] In this embodiment, one of the first male connector and the first female connector is a first guide block 420 and the other is a first linear guide rail 210. The first linear guide rail 210 can move relative to the first guide block 420 along the length direction of the first linear guide rail 210. One of the second male connector and the second female connector is a second guide block 240 and the other is a second linear guide rail 330. The second linear guide rail 330 can move relative to the second guide block 240 along the length direction of the second linear guide rail 330.

[0051] The design of the linear guide rail and guide block, working together, enables the first lifting frame 200 to slide stably on the fixed frame 400 and the second lifting frame 300 to slide stably on the first lifting frame 200. This guiding design improves the smoothness and reliability of the secondary telescopic mechanism. The aforementioned dual guiding design further enhances the operational stability and precision of the secondary telescopic mechanism, ensuring the safety of the product 500 during transport, thereby improving the overall smoothness and reliability of the secondary telescopic mechanism.

[0052] In this embodiment, the first male connector is a first guide block 420, and the first female connector is a first linear guide rail 210; the second male connector is a second guide block 240, and the second female connector is a second linear guide rail 330. Specifically, the linear guide rail is a miniature linear guide rail.

[0053] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
