Description

Technical Field

[0001] This utility model relates to the field of screening equipment technology, and in particular to a discharge guide plate for a swing-adjustable screening machine. Background Technology

[0002] Screening machines are widely used material grading equipment in industrial production. During operation, the screened material needs to be guided to the next process or collection container through specific channels or devices. The discharge guide plate is a key component for achieving this function, directly affecting the smoothness and accuracy of the discharge.

[0003] To accommodate materials with different particle sizes, moisture content, and flow characteristics, and to meet the requirements for discharge positions under different working conditions, some discharge guide plates are designed with adjustable structures. By adjusting the tilt angle of the guide plate, the falling speed and flow pattern of the material can be optimized; by adjusting the horizontal position of the guide plate, it can be aligned with different collection ports, thereby enhancing the versatility and flexibility of the equipment.

[0004] However, screening machines generate high-frequency, intense vibrations during operation. While existing adjustable guide plates offer adjustment capabilities, their locking mechanisms are typically quite simple, relying solely on the friction of a single bolt for fixation. Under such continuous vibration and impact, the locking mechanism can loosen, causing the preset tilt angle and horizontal position to gradually shift. This instability not only leads to material spillage, blockages, or cross-contamination, affecting production efficiency and product quality, but also poses safety hazards due to component detachment. Therefore, achieving long-term, reliable locking of the guide plate after adjustment under strong vibration conditions is a pressing technical challenge that needs to be addressed by existing technologies.

[0005] Therefore, this utility model proposes a swing-adjustable discharge guide plate for a screening machine to address the shortcomings of the prior art. Utility Model Content

[0006] In view of the problems in the existing technology of the discharge guide plate of the swing-adjustable screen, such as the simple locking structure and the loosening under strong vibration of the screen, which leads to the instability of the preset angle and position, the present invention aims to provide a swing-adjustable screen discharge guide plate with an improved structure that can effectively solve the above problems.

[0007] This utility model provides a discharge guide plate for an oscillating adjustable screening machine, including a plate body, a rotating mechanism fixedly connected to the plate body, and a moving mechanism connected to the rotating mechanism; the rotating mechanism includes a rotating seat, a rotating cylinder rotatably connected to the rotating seat, and a rotating shaft passing through the two; the moving mechanism includes a slide rail fixed to the rotating seat and a connecting mechanism slidably engaged with the slide rail; the device also includes a bolt seat fixed to the plate body, a first bolt installed in the bolt seat, and an eccentric wheel rotatably installed on the rotating seat.

[0008] The shaft has a tapered hole at one end, and the first bolt has a tapered friction protrusion that matches the tapered hole at one end. The first bolt is threaded to the bolt seat. By tightening the first bolt, the tapered friction protrusion is wedged into the tapered hole. The huge positive pressure generated by the tapered surface forms a friction self-locking mechanism, thereby achieving reliable locking of the rotation angle.

[0009] Furthermore, the eccentric surface of the eccentric wheel presses against the slide rail and the connecting mechanism. By rotating the eccentric wheel, the position of the connecting mechanism can be quickly and securely locked by its eccentric pressure.

[0010] Preferably, the rotating mechanism further includes a clamping assembly to form a double lock. The clamping assembly includes a bolt seat two and a second bolt installed therein. The bolt seat two is fixed to the bolt seat one. The axis of the second bolt is perpendicular to the axis of the first bolt, and its end can press against the head of the first bolt to apply additional auxiliary pressure, which greatly enhances the angle locking stability in a vibration environment.

[0011] Preferably, a washer is provided between the first bolt and the bolt seat. The washer increases the contact friction between the two, which can effectively prevent the first bolt from rotating in the opposite direction and loosening due to high-frequency vibration of the equipment, thus further ensuring the reliability of the locking.

[0012] Preferably, the connecting mechanism is specifically composed of a mounting plate and a T-slot. The mounting plate is fixedly connected to the T-slot, and the outer contour of the mounting plate forms a sliding fit with the inner cavity of the slide rail. This design ensures the smoothness and guiding accuracy of the guide plate when adjusting its horizontal position.

[0013] Preferably, as a specific implementation of the installation structure, the T-slot is also provided with multiple bolt holes, which allow the user to securely install the entire device into the predetermined position of the screening equipment body using bolts.

[0014] Preferably, in order to maximize the locking effect, the inner wall of the tapered hole of the rotating shaft is roughened. This roughened surface significantly increases the static friction coefficient when in contact with the tapered friction protrusion of the first bolt, making the angle locking more secure.

[0015] Preferably, as a further reinforcement of the locking structure, the outer surface of the tapered friction protrusion of the first bolt is knurled. The knurled surface can also increase the frictional force in contact with the inner wall of the tapered hole. Together with the roughened inner wall of the tapered hole, it ensures that the locking is foolproof under strong vibration conditions.

[0016] This utility model has the following beneficial effects: 1. This utility model solves the problems of inconvenient guide plate angle adjustment and unreliable locking under screen vibration and easy angle instability in the prior art by setting a double locking rotation mechanism consisting of a first bolt with a conical end wedged into the rotating shaft and a second bolt for auxiliary clamping. It achieves the technical effect of accurate discharge angle adjustment, stable locking and strong vibration resistance.

[0017] 2. This utility model solves the problems of fixed guide plate position, inability to adapt to different discharge positions, and poor adaptability in the prior art by setting a moving mechanism that is slidably engaged by a slide rail and a connecting mechanism and uses an eccentric wheel for rapid pressing and locking. It achieves the technical effects of a large range of guide plate position adjustment, convenient and rapid operation, and reliable locking.

[0018] 3. This utility model has an ingenious overall structural design, which organically combines the two adjustment functions of angle and position. All components work together, and the locking mechanism fully considers the vibration conditions, making the device not only fully functional but also stable and durable, greatly improving the flexibility and practicality of the material discharge process of the screening machine.

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0022] Example: Please refer to Figures 1 to 4 This utility model provides a swing-adjustable discharge guide plate for a screen, which aims to solve the problems of fixed structure, inconvenient adjustment, and easy instability of angle and position of the discharge guide plate in the prior art under vibration conditions.

[0023] like Figure 1 As shown, a swing-adjustable screen discharge guide plate includes a plate body 1, a rotating mechanism 2, and a moving mechanism 3. The rotating mechanism 2 is fixedly connected to the plate body 1 and is used to adjust the tilt angle of the plate body 1. The moving mechanism 3 is fixedly connected to the rotating mechanism 2 and is used to adjust the horizontal position of the entire device. The rotating mechanism 2 includes a rotating base 207 and a rotating cylinder 201 fixedly connected to the plate body 1 and rotatably connected to the rotating base 207. A rotating shaft 202 passes through the rotating cylinder 201 and the rotating base 207 and serves as the central axis for the rotation of the rotating cylinder 201 relative to the rotating base 207. The moving mechanism 3 includes a slide rail 301 fixed to one side of the rotating base 207 and a connecting mechanism 302 that slides with the slide rail 301. As one of the innovations of this solution, the rotating mechanism 2 is equipped with an angle locking structure. The angle locking structure includes a bolt seat 203 fixed to the plate 1 and a first bolt 204 threaded to the bolt seat 203. The end of the rotating shaft 202 is provided with a tapered hole, and the end of the first bolt 204 has a tapered friction protrusion that matches the tapered hole. When it is necessary to lock the angle of the plate 1, the first bolt 204 is tightened, and its tapered friction protrusion will wedge into the tapered hole, thereby generating a huge radial locking force on the rotating shaft 202 and realizing stable angle locking. As another innovation of this solution, the moving mechanism 3 is equipped with a position locking structure, which includes an eccentric wheel 303. The eccentric wheel 303 is rotatably mounted on the rotary seat 207, and the eccentric surface of the eccentric wheel 303 presses against the slide rail 301 and the connecting mechanism 302. By moving the eccentric wheel 303, the connecting mechanism 302 can be quickly and easily locked firmly at any position on the slide rail 301 by using its eccentric pressure.

[0024] To ensure the reliability of angle locking, a shim 205 is provided between the head of the first bolt 204 and the bolt seat 203 in the rotating mechanism 2. The shim 205 is used to increase the friction between the head of the first bolt 204 and the inner wall of the bolt seat 203 to prevent the first bolt 204 from rotating in the opposite direction and loosening under the condition of strong vibration of the screening machine, thereby ensuring the stability of angle adjustment. Meanwhile, a clamping assembly 206 is also provided on the rotating mechanism 2 to form a secondary reinforcement for angle locking; the clamping assembly 206 includes a bolt seat 2062 and a second bolt 2061 installed in the bolt seat 2062. The bolt seat 2062 is fixed on the bolt seat 1 203. The axis of the second bolt 2061 is perpendicular to the axis of the first bolt 204. After the second bolt 2061 is tightened, its end will press against the head of the first bolt 204, thereby applying an auxiliary clamping force to the first bolt 204, further enhancing the wedging friction between the first bolt 204 and the rotating shaft 202, effectively preventing loosening and angle instability of the plate 1 caused by the vibration of the screening machine. For the rotating shaft 202 in the rotating mechanism 2, the inner wall of the tapered hole at its end is roughened. The roughened surface is used to increase the static friction force when in contact with the tapered friction protrusion, thereby improving the reliability of angle locking. In addition, the outer surface of the tapered friction protrusion of the first bolt 204 is also designed as a knurled surface. The knurled surface is used to increase the static friction force when in contact with the inner wall of the tapered hole, thereby enhancing the stability of angle locking.

[0025] As a preferred embodiment, please refer to Figure 4 In order to achieve the horizontal position adjustment of the guide plate, the connecting mechanism 302 in the moving mechanism 3 specifically includes a mounting plate 3021 and a T-slot 3022; the mounting plate 3021 and the T-slot 3022 are fixedly connected, and the outer contour of the mounting plate 3021 slides in conjunction with the inner cavity of the slide rail 301. This structure enables the mounting plate 3021 to drive the T-slot 3022 to slide smoothly along the length direction of the slide rail 301, thereby changing the overall position of the plate 1. As a further limitation of the above scheme, and continuing to refer to... Figure 4 In order to reliably install the entire guide plate device on the screening equipment, the T-slot 3022 is provided with multiple bolt holes, which are used to fix the connecting mechanism 302 to the body of the screening device by bolts.

[0026] Working principle: After screening, the material enters the storage area through plate 1. During this process, the function of rotating mechanism 2 is to adjust the tilt angle of plate 1 to adapt to the discharge requirements of materials of different particle sizes, such as granules and powders. Plate 1 rotates in the middle of rotating base 207 via rotating drum 201. Rotating shaft 202 passes through both of them, with tapered holes at both ends. The holes are roughened. Bolt seat 203 is fixed to plate 1, and the first bolt 204 is installed inside. The end of the first bolt 204 is machined with tapered friction protrusions that match the tapered holes on rotating drum 201. The surface is knurled to increase friction. When plate 1 is flipped, rotating drum 201 and rotating base 207 rotate relative to each other around rotating shaft 202, thus adjusting the angle of plate 1. After adjustment, use a wrench to rotate the first bolt 204 so that its end is wedged into the rotating shaft 202. The rotation angle is locked by friction. A shim 205 is placed between the first bolt 204 and the bolt seat 203 to increase the friction between the two contact surfaces and prevent the first bolt 204 from rotating in the opposite direction and loosening. The function of the clamping assembly 206 is to assist in clamping the first bolt 204 and increase the friction at the contact surface between the first bolt 204 and the rotating shaft 202. The second bolt 2061 rotates in the bolt seat 2062. Tightening the second bolt 2061 causes its end to press inward against the end of the first bolt 204 to prevent loosening and angle instability of the plate 1 caused by the vibration of the screening machine. The function of the moving mechanism 3 is to change the position of the plate 1 on the screening equipment, so as to adapt to different discharge positions. The slide rail 301 is fixed on one side of the rotary seat 207, and the connecting mechanism 302 is directly fixed to the screening device body. The T-slot 3022 has multiple bolt holes, and the connecting mechanism 302 is connected to the equipment by bolts. The T-slot 3022 moves horizontally relative to the shim 205 in the slide rail 301 through the mounting plate 3021, changing the position of the plate 1. After the adjustment is completed, the eccentric wheel 303 is turned. Its eccentric structure presses the slide rail 301 and the T-slot 3022 downward to complete the position locking and prevent the screening machine from slipping during vibration operation.
