Description

Technical Field

[0001] This utility model relates to a feeding device for a roller press, and more specifically, to a lever-type feeding device for a roller press. Background Technology

[0002] Because roller presses have strict requirements for feeding, only a stable feed flow can guarantee the crushing effect and efficiency of the roller press. Achieving stable feeding and online adjustment during roller press operation is also crucial for the equipment. This is because the material pressure is high when feeding into a roller press, making adjustment difficult with conventional feeding devices. Summary of the Invention

[0003] The technical problem to be solved by this utility model is to provide a lever-type feeding device for a roller press, which can adjust the size and angle of the feed inlet online during the operation of the roller press.

[0004] The technical solution adopted by this utility model to solve its technical problem is as follows: Construct a lever-type feeding device for a roller press, including a push rod device, a feed hopper, a valve plate support and a valve plate. The valve plate support and the valve plate are arranged inside the feed hopper. The push rod device includes a drive motor, a screw and a connecting rod. The drive motor drives the screw to move linearly. The connecting rod is fixed to the end of the screw. The middle part of the valve plate is hinged to the valve plate support and the upper end of the valve plate is hinged to the connecting rod.

[0005] According to the above scheme, the drive motor is a helical gear worm gear reducer motor.

[0006] According to the above scheme, the drive motor is mounted on the push rod base.

[0007] According to the above scheme, the feed hopper is fixed on the support frame.

[0008] According to the above scheme, the push rod device also includes an angle sensor, which is used to receive the position signal of the valve plate opening degree.

[0009] According to the above scheme, there are two valve plate supports and valve plates, and the two valve plates are respectively connected to two push rod devices.

[0010] The lever-type feeding device for the roller press of this utility model has the following beneficial effects:

[0011] 1. The middle part of the valve plate is hinged to the valve plate support, and the upper end of the valve plate is hinged to the connecting rod, forming a lever structure. Using a lever-type valve plate can reduce the load on the adjusting screw, making the valve plate adjustment more effortless and flexible.

[0012] 2. The drive motor can use a helical gear worm gear reducer motor, which makes the transmission more precise and stable. Equipped with an angle sensor, it accurately transmits the valve plate opening to the central control system, realizing real-time tracking, precise control, and closed-loop adjustment. Attached Figure Description

[0013] The present invention will be further described below with reference to the accompanying drawings and embodiments. In the accompanying drawings:

[0014] Figure 1 This is a schematic diagram of the structure of the lever-type feeding device for the roller press of this utility model;

[0015] Figure 2 This is a schematic diagram of the push rod device. Detailed Implementation

[0016] To provide a clearer understanding of the technical features, objectives, and effects of this utility model, the specific embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0017] like Figure 1-2 As shown, the lever-type feeding device for the roller press of this utility model includes a push rod device 1, a feed hopper 6, a valve plate support 4, and a valve plate 5. In this embodiment, there are two valve plate supports 4 and two valve plates 5, and the two valve plates 5 are respectively connected to two push rod devices 1, and the opening and closing are achieved by the two valve plates 5 opening and closing.

[0018] Valve plate support 4 and valve plate 5 are disposed inside feed hopper 6. Push rod device 1 includes drive motor 8, screw 9 and connecting rod 10. Drive motor 8 drives screw 9 to move linearly. Connecting rod 10 is fixed to the end of screw 9. The middle part of valve plate 5 is hinged to valve plate support 4 and the upper end of valve plate 5 is hinged to connecting rod 10.

[0019] Preferably, in this embodiment, the drive motor 8 is a helical gear worm gear reducer motor.

[0020] Preferably, in this embodiment, the drive motor 8 is mounted on the push rod base 2.

[0021] Preferably, in this embodiment, the feed hopper 6 is fixed on the support frame 3.

[0022] Preferably, the push rod device 1 in this embodiment further includes an angle sensor 7, which is used to receive the position signal of the valve plate opening degree.

[0023] The working principle of this utility model is as follows:

[0024] A helical gear worm gear reducer motor drives the screw 9 to move back and forth. The rotation of the helical gear worm gear reducer motor is converted into thrust or pull force through the thread, causing the connecting rod 10 to pull the valve plate 5 to open and close. The central control system issues opening requirements, controlling the forward and reverse rotation of the drive motor 8 to switch the opening and closing actions of the valve plate 5 and adjust the speed. An angle sensor 7 receives the position signal of the valve plate 5's opening degree and feeds the result back to the central control system. This ensures that the central control system receives position signals in real time when adjusting the valve plate 5, achieving a closed-loop effect for the valve plate 5 adjustment commands. The valve plate support 4 and the valve plate 5 form a lever structure, reducing the load on the screw 9, making adjustment easier, and allowing for more flexible opening and closing of the valve plate 5.

[0025] The embodiments of the present invention have been described above with reference to the accompanying drawings. However, the present invention is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of the present invention without departing from the spirit and scope of the claims. All of these forms are within the protection scope of the present invention.
