Description

Technical Field

[0001] This utility model relates to the field of feeding equipment technology, and more specifically, to a multi-stage material pusher device. Background Technology

[0002] Material pushers play a vital role in many industrial scenarios such as material handling.

[0003] Based on the above, the inventors have discovered that most existing material pushing devices employ a single-stage pushing structure. During the pushing process, materials are prone to deviation and jamming, and the pushing stroke range is relatively small, resulting in poor material pushing flexibility and difficulty in adapting to the pushing needs of different materials. Furthermore, some pushing devices lack an effective force feedback mechanism, failing to monitor changes in pushing force in real time. When materials become stuck, it can easily cause motor overload or component damage, affecting production efficiency and equipment lifespan. Therefore, in view of this, the inventors have researched and improved the existing structure to provide a multi-stage material pushing device, aiming to achieve a more practical and valuable solution. Utility Model Content

It can add a primary guiding mechanism and a secondary guiding mechanism, and under the combined drive of a dual-output shaft reducer, a swing arm, a three-phase drive motor, linear guide rails, and a slide block, it effectively solves the problems of material deviation and jamming, small pushing stroke range, poor material pushing flexibility, and lack of force feedback mechanism that can easily cause motor overload or component damage caused by the single-stage pushing structure of existing pushing devices. It improves the stability, adaptability, and safety of the material pushing process, extends the service life of the equipment, and ensures production efficiency.

[0006] 2. Technical Solution

[0007] To solve the above problems, the present invention adopts the following technical solution.

[0008] A multi-stage material pusher device includes a pusher plate and two mounting bases. A linear guide rail is fixedly mounted on the top of the pusher plate. Two slide blocks are slidably connected to the top of the linear guide rail. A connecting rod is fixedly connected to the top of the slide blocks. A dual-output shaft reducer is fixedly mounted on the bottom of the mounting base. A swing arm is provided between the longitudinal output shaft of the dual-output shaft reducer and the top of the corresponding connecting rod. A primary guide mechanism is provided above both ends of the pusher plate. A secondary guide mechanism is movably connected to the bottom of the primary guide mechanism. The bottom of the secondary guide mechanism is fixedly connected to the top of the pusher plate by a bracket.

[0009] Furthermore, the primary guide mechanism includes a primary guide seat, a guide rod is fixedly connected to the bottom of the primary guide seat, two movable seats are slidably connected to the outer periphery of the guide rod, and fixed seats are fixedly connected to the top of both ends of the primary guide seat.

[0010] Furthermore, the secondary guide mechanism includes a secondary guide seat fixed between the bottoms of the two movable seats, a slide rail fixedly connected to the bottom of the secondary guide seat, a slider slidably connected to the outer periphery of the slide rail, and the bottom of the slider fixedly connected to the top of the bracket.

[0011] Furthermore, both ends of the secondary guide seat are fixedly connected to magnetic suction seats, and both ends of the slider are fixedly connected to magnetic suction blocks that are compatible with the magnetic suction seats.

[0012] Furthermore, the two transverse output shafts of the two dual-output shaft reducers are connected by a transmission rod via a coupling at their ends that are close to each other.

[0013] Furthermore, one end of one of the dual-output shaft reducers is equipped with a three-phase drive motor, and the output shaft of the three-phase drive motor is connected to the other end of the transverse output shaft of the dual-output shaft reducer via a coupling.

[0014] Furthermore, the swing arm includes a main arm connected to the longitudinal output shaft of the dual-output shaft reducer via a key.

[0015] 3. Beneficial effects

[0016] Compared with existing technologies, the advantages of this utility model are:

[0017] (1) In this scheme, the primary guide mechanism and the secondary guide mechanism work together to guide the moving seat laterally using the guide rod at the bottom of the primary guide seat, so that the pusher plate can push the material once. The slide rail and slider at the bottom of the secondary guide seat work together to enable the pusher plate to push the material twice. The dual guiding effect effectively limits the offset of the pusher plate during the pushing process, avoids the material from getting stuck due to the unstable pushing trajectory, improves the smoothness of material pushing, and extends the pushing stroke of the material, thereby meeting the pushing needs of different materials and greatly improving the overall applicability and flexibility.

[0018] (2) In this solution, by setting a force sensor between the main arm and the auxiliary arm of the swing arm, the changes in the pushing force on the material during the pushing process can be monitored in real time. When the material gets stuck and the pushing force exceeds the preset threshold, the force sensor can feed the signal back to the control system, and control the three-phase drive motor to stop running in time to avoid damage to the motor due to overload. At the same time, it also protects the push plate, guide mechanism and other components from excessive impact force, extends the overall service life of the equipment, and reduces the equipment maintenance cost in the production process.

[0036] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0037] Example:

[0038] Please see Figures 1-4 A multi-stage material pusher device includes a pusher plate 1 and two mounting bases 2. A linear guide rail 3 is fixedly installed on the top of the pusher plate 1. Two slide blocks 4 are slidably connected to the top of the linear guide rail 3. In use, the linear guide rail 3 and the slide blocks 4 cooperate to accurately guide the movement direction of the pusher plate 1 and effectively prevent the material from deviating during the pushing process. A connecting rod 5 is fixedly connected to the top of the slide block 4. A double-output shaft reducer 6 is fixedly installed at the bottom of the mounting base 2. A swing arm 7 is provided between the longitudinal output shaft of the double-output shaft reducer 6 and the top of the corresponding connecting rod 5. A primary guide mechanism 8 is provided above both ends of the pusher plate 1. A secondary guide mechanism 9 is movably connected to the bottom of the primary guide mechanism 8. The bottom of the secondary guide mechanism 9 is fixedly connected to the top of the pusher plate 1 by a bracket 10.

[0039] See Figure 3 and Figure 4 The primary guide mechanism 8 includes a primary guide seat 801, a guide rod 802 is fixedly connected to the bottom of the primary guide seat 801, two movable seats 803 are slidably connected to the outer periphery of the guide rod 802, and fixed seats 804 are fixedly connected to the top of both ends of the primary guide seat 801.

[0040] See Figure 3 and Figure 4 The secondary guide mechanism 9 includes a secondary guide seat 901 fixed between the bottoms of two movable seats 803. A slide rail 902 is fixedly connected to the bottom of the secondary guide seat 901. A slider 903 is slidably connected to the outer periphery of the slide rail 902. The bottom of the slider 903 is fixedly connected to the top of the bracket 10.

[0041] See Figure 4 Both ends of the secondary guide seat 901 are fixedly connected to magnetic suction seats 904, and both ends of the slider 903 are fixedly connected to magnetic suction blocks 905 that are compatible with magnetic suction seats 904.

[0042] See Figure 2The transverse output shafts of the two dual-output shaft reducers 6 are connected by a transmission rod 11 via a coupling at their close ends. One end of one of the dual-output shaft reducers 6 is equipped with a three-phase drive motor 12, and the output shaft of the three-phase drive motor 12 is connected to the other end of the transverse output shaft of the dual-output shaft reducer 6 via a coupling. During use, the dual-output shaft reducers 6 rotate synchronously through the transmission rod 11, ensuring that the driving force of the two swing arms 7 on the push plate 1 is balanced, preventing the push plate 1 from tilting due to excessive driving force on one side, and further improving the stability of the pushing process. The three-phase drive motor 12 provides power to the dual-output shaft reducers 6, and its output speed can be adjusted by the control system to achieve precise control of the pushing speed of the push plate 1, meeting the differentiated speed requirements under different material pushing scenarios.

[0043] See Figure 2 The swing arm 7 includes a main arm 701 connected by a key to the longitudinal output shaft of the dual-output shaft reducer 6. A force sensor 702 is fixedly mounted at one end of the main arm 701, and a secondary arm 703 is fixedly mounted at the other end of the force sensor 702. The bottom of the secondary arm 703 is rotatably connected to the top of the connecting rod 5 via a bearing. During use, the coordinated operation of the dual-output shaft reducer 6 and the swing arm 7 ensures efficient and stable power transmission. Simultaneously, the force sensor 702, installed between the main arm 701 and the secondary arm 703, can monitor changes in material weight in real time. When a difference in material weight is detected, the force sensor 702 quickly feeds the data back to the control system, thereby adjusting the output power of the three-phase drive motor 12. This allows the pushing force and speed to flexibly match the actual needs of the material, thus adapting to the handling tasks of materials of different specifications and weights.

[0044] In use: After the three-phase drive motor 12 starts, its output shaft drives the corresponding dual-output shaft reducer 6 to rotate horizontally through the coupling. Then, the power is synchronously transmitted to another dual-output shaft reducer 6 through the transmission rod 11, so that the longitudinal output shafts of the two dual-output shaft reducers 6 rotate synchronously, thereby driving the swing arm 7 to swing. The main arm 701 of the swing arm 7 drives the auxiliary arm 703 to move. The auxiliary arm 703 pushes the slide block 4 to slide along the linear guide rail 3 through the connecting rod 5, thereby driving the pusher plate 1 to move as a whole. In this process, firstly, the moving seat 803 of the primary guide mechanism 8 slides along the guide rod 802 to provide primary guide support for the pusher plate 1, so that the pusher plate 1 and other components can move forward as a whole. When the moving seat 803 moves to the end of the guide rod 802 and can no longer move, the magnetic block 905 separates from the magnetic seat 904 under the action of the thrust. The slider 903 of the secondary guide mechanism 9 slides along the slide rail 902, driving the pusher plate 1 to perform secondary pushing, ensuring the smooth movement of the pusher plate 1 while also increasing the pushing stroke of the pusher plate 1. At the same time, the force sensor 702 monitors the thrust data in real time during the pushing process. If the thrust exceeds the set threshold, it immediately feeds back a signal to the control system, and the control system then controls the three-phase drive motor 12 to stop running to protect the equipment safety. The fixed base 804 can stably install the primary guide seat 801 on the external frame or worktable, ensuring that the entire guiding mechanism will not shake or shift during operation, providing a solid structural foundation for material pushing.
