Description

Technical Field

[0001] This utility model relates to the field of material conveying equipment technology, specifically to an anti-collision protection device for powder feeding equipment. Background Technology

[0002] In industrial production, the processing of fine powdery materials is a common step. For example, in the production of electronic materials, powder metallurgy, and feed, it is necessary to precisely fill fine powdery materials into specific containers. For instance, when powdery materials are fed into a platen furnace via a auger from a feeding hopper, the feeding hopper's discharge port needs to be lowered to the top of the furnace to prevent excessive powder spillage. Due to unevenness in the partitions caused by use or uneven installation of the platen furnace, the feeding hopper's discharge port often collidees with the platen during loading, resulting in damage to the discharge port or the platen itself. Manual intervention poses safety risks, and existing technologies using mechanical limit devices suffer from difficulties in adjustment and poor buffering performance, failing to effectively address the collision protection requirements under complex operating conditions.

[0003] Therefore, how to develop a safer and more efficient anti-collision protection device for use in feed hoppers has become a technical problem that the industry urgently needs to solve. Utility Model Content

[0004] Purpose of the utility model: In order to overcome the shortcomings of the existing technology, this utility model provides a collision protection device that can solve the problem of the inability of the existing technology to safely and efficiently protect the feed bin.

[0005] Technical solution: Collision avoidance protection device, including:

[0006] Mounting plate, used to connect and secure to the feed hopper;

[0007] A lever located above the mounting plate;

[0008] Contact components used to contact obstacles;

[0009] A guide telescopic rod is provided through the mounting plate and is used to connect the lever and the contact member;

[0010] The buffer protection mechanism includes a gate-shaped component fixedly connected to the top of the mounting plate, and the inner top of the gate-shaped component is elastically connected to the lever;

[0011] And including a sensor switch for responding to the position of the lever and issuing a stop signal to the feed hopper.

[0012] Furthermore, the gate-shaped component is provided with a screw, the top end of the screw is fixedly connected to the gate-shaped component, the bottom end of the screw is fixedly connected to the lever, and an elastic element is sleeved on the screw.

[0013] Furthermore, a first nut is fitted onto the top end of the screw, and the first nut is positioned above the portal member to adjust the tension of the elastic element.

[0014] Furthermore, a second nut is fitted at the bottom end of the screw, and the second nut is positioned below the lever to fix the lever.

[0015] Furthermore, the mounting plate is configured to be disposed between two feeding bins and connected to the two feeding bins respectively, the buffer protection mechanism is configured to be two respectively disposed at both ends of the mounting plate, the number of the paddle is configured to be one, and the two buffer protection mechanisms are connected to one paddle.

[0016] Furthermore, the elastic element is a spring.

[0017] Beneficial Effects: This novel anti-collision protection device, through the above-described scheme, ensures that when the feed hopper descends at a constant speed, if the contact component has not yet contacted the box plate surface, the buffer protection mechanism is in a free state. After the contact component contacts the protruding box plate, the buffer protection mechanism begins to retract, gradually absorbing the impact energy. When the compression stroke reaches a set threshold, a lever triggers an inductive switch, thereby initiating braking on the feed hopper. This method achieves gradient transmission of impact force, improving the protection effect, and the mechanical detection avoids the risk of electronic component failure. Attached Figure Description

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0023] It should be noted that the descriptions involving "first," "second," etc., in this utility model are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them.

[0024] See Figure 1-3 An embodiment of the anti-collision protection device of this utility model, as shown, includes: a mounting plate 11, a lever 16, a contact member 12, a guide telescopic rod 13, a buffer protection mechanism, and an inductive switch 17. The mounting plate 11 is connected to and fixed to the feeding bin 3, and the lever 16 is positioned above the mounting plate 11. The contact member 12 is positioned vertically below the feeding bin 3 to contact obstacles such as the box plate. The guide telescopic rod 13 extends through the mounting plate 11, and both ends of the guide telescopic rod are used to connect the lever 16 and the contact member 12.

[0025] The buffer protection mechanism includes a portal-shaped member 15 fixedly connected to the top of the mounting plate 11, with the lever 16 elastically connected to the inner top of the portal-shaped member 15. A sensor switch 17 is used to respond to the position of the lever 16 and send a stop signal to the feeding bin 3.

[0026] Through the above scheme, when the feed bin 3 descends at a constant speed, if the contact member 12 does not contact the surface of the box plate 2, the buffer protection mechanism is in a free state. After the contact member 12 contacts the raised box plate 2, the buffer protection mechanism begins to retract, gradually absorbing the impact energy. When the compression stroke reaches the set threshold, the lever 16 triggers the inductive switch 17, thereby initiating braking on the feed bin 3. This method can achieve gradient transmission of impact force, improve the protection effect, and the mechanical detection avoids the risk of electronic component failure.

[0027] Specifically, the gate-shaped component 15 is provided with a screw 18, the top end of which is fixedly connected to the gate-shaped component 15, and the bottom end of which is fixedly connected to the lever 16. An elastic element 14 is sleeved on the screw 18. Preferably, the elastic element 14 is a spring. Through the cooperation of the gate-shaped component 15 and the screw 18, not only is a buffering and protective function provided, but a guiding function is also provided.

[0028] In some preferred embodiments, a first nut 181 is fitted onto the top end of the screw 18, and the first nut 181 is positioned above the portal member 15 to adjust the tension of the elastic element 14. A second nut 182 is also fitted onto the bottom end of the screw 18, and the second nut 182 is positioned below the lever 16 to fix the lever 16, and the second nut 182 can be used to adjust the tension of the elastic element 14.

[0029] In some preferred embodiments, such as Figure 3 As shown, the mounting plate 11 is configured to be placed between and connected to the two feeding bins 3 respectively. Two buffer protection mechanisms are configured, each located at one end of the mounting plate 11. One lever 16 is configured, and the two buffer protection mechanisms are connected to the same lever 16. In this way, the same anti-collision protection device 1 can simultaneously protect both feeding bins 3, improving efficiency.

[0030] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
