Abstract
Description
Technical Field
[0001] This utility model relates to the field of feeders, specifically a switching component for feeders. Background Technology
[0002] In multi-station production scenarios such as food processing, pharmaceutical preparation, and chemical synthesis, the feeder, as a key piece of equipment for material distribution, needs to accurately deliver materials from a single source to different downstream processing units. These production scenarios place stringent requirements on the feeder's discharge switching efficiency, material conveying stability, and ease of maintenance.
[0003] Traditional feeder discharge structures often employ manual valve switching or multi-pipeline independent control modes. In manual valve switching feeders, the discharge pipe is connected to the main hopper via a manual gate valve. Operators must rotate the valve handle to change the material flow direction. This switching process requires manual intervention, and a single switch typically takes more than 30 seconds. For high-speed production lines with high throughput, this can lead to material conveying interruptions, severely impacting production continuity. Furthermore, manual operation is prone to cross-contamination due to incomplete valve closure. For example, if flour is not fully closed during switching, it may flow into two devices simultaneously, causing material waste and product contamination.
[0004] In terms of material conveying stability, gaps often form between the hopper outlet and the discharge pipe of traditional feeders due to insufficient docking precision, leading to material leakage. During the conveying process, the material will fly out from the gaps, resulting in a high material loss rate. Utility Model Content
[0005] The purpose of this invention is to provide a switching component for a feeder, which aims to solve the problems of cumbersome operation and easy material loss of existing feeders.
[0006] This utility model is implemented as follows: A switching assembly for a feeder includes a frame, which includes a top frame and vertical frames. There are two sets of vertical frames, which are symmetrically installed at the front end of the top frame and fixedly connected to the top frame. A feeding box assembly is also fixedly installed between the two sets of vertical frames. A guide shell is installed directly below the feeding box assembly. The two sides of the guide shell are fixedly installed on the inner sides of the vertical frames. A switching disc assembly is rotatably installed at the lower end of the guide shell. A drive motor for driving the switching disc assembly to rotate is also fixedly installed on the guide shell. A first discharge pipe, a second discharge pipe, and a third discharge pipe are evenly installed along the circumferential direction on the lower end face of the switching disc assembly. The first discharge pipe, the second discharge pipe, and the third discharge pipe are all detachably and fixedly connected to the switching disc assembly.

[0009] Preferably, an outer ear seat that mates with the inner support seat is installed on the outer side of the column box shell. The outer ear seat is fixedly connected to the column box shell and is fixed to the inner support seat by bolts.
[0010] Preferably, the guide shell includes a disc shell with an opening at the lower end and a side plate connected to the vertical plate. The side plate is fixedly installed on both sides of the disc shell, and the upper end surface of the disc shell has a drainage groove corresponding to the lower end of the conical guide shell.

[0021] The following description, in conjunction with the accompanying drawings and specific embodiments, provides further details:
[0022] Reference Figure 1 , Figure 2 and Figure 3As shown, a switching assembly for a feeder includes a frame 1, which comprises a top frame 11 and vertical frames 12. Two sets of vertical frames 12 are symmetrically installed at the front end of the top frame 11 and are fixedly connected to it. A feeding box assembly 2 is fixedly installed between the two sets of vertical frames 12. A guide shell 3 is installed directly below the feeding box assembly 2. The two sides of the guide shell 3 are fixedly installed on the inner sides of the vertical frames 12. A switching disc assembly 4 is rotatably installed at the lower end of the guide shell 3. A drive motor 30 for driving the switching disc assembly 4 is also fixedly installed on the guide shell 3. A first discharge pipe 5, a second discharge pipe 6, and a third discharge pipe 7 are evenly installed along the circumferential direction on the lower end face of the switching disc assembly 4. All three discharge pipes are detachably and fixedly connected to the switching disc assembly 4. The top frame 11 and vertical frames 12 of the frame 1 constitute the basic framework structure of the entire assembly, providing stable support for other components. Two sets of symmetrical vertical frames 12 ensure the balance and stability of the structure. The feeding box group 2 is used to store the materials to be fed, and the guide shell 3 guides the material flow to the switching disc group 4. The drive motor 30 can drive the switching disc group 4 to rotate, thereby realizing the switching of the first discharge pipe 5, the second discharge pipe 6, and the third discharge pipe 7, which facilitates the feeding of materials to different positions. The discharge pipes are detachably fixed to the switching disc group 4, which facilitates the replacement, cleaning, or maintenance of the discharge pipes and improves the maintainability of the components. The drive motor 30 can be a three-phase asynchronous motor of model Y80M1-2. This model of motor has the advantages of large starting torque and stable operation, which can meet the power requirements of the switching disc group 4. The vertical frame 12 includes a vertical plate 121 and an inner support 122 for mounting the feeding box group 2. The inner support 122 is installed on the inner side of the vertical plate 121, and the inner support 122 is integrally formed with the vertical plate 121. The upright plate 121, as the main supporting component of the vertical frame 12, provides vertical support for the entire assembly. The inner support 122 is used to install the feeding box assembly 2. The one-piece molding design ensures the connection strength and stability between the inner support 122 and the upright plate 121, allowing the feeding box assembly 2 to be firmly installed on the vertical frame 12, preventing shaking or displacement during use, and ensuring the accuracy and stability of material feeding. The upright plate 121 and the inner support 122 of the vertical frame 12 can be made of Q235 carbon structural steel, which has good strength and toughness and can withstand a certain weight and external force.
[0023] Reference Figure 1 and Figure 4As shown, the feeding box assembly 2 includes a columnar shell 21 and a conical guide shell 22. A cover 211 is detachably mounted on the upper surface of the columnar shell 21, and the conical guide shell 22 is integrally formed on the lower surface of the columnar shell 21. The columnar shell 21 is used to store materials. The detachable cover 211 facilitates adding materials to the columnar shell 21 and also allows for easy cleaning or maintenance of the interior of the columnar shell 21. The conical guide shell 22 is designed to smoothly guide the materials inside the columnar shell 21 into the guide shell 3, reducing blockages during material transport and ensuring smooth material delivery. Both the columnar shell 21 and the conical guide shell 22 can be made of stainless steel, such as 304 stainless steel, which has advantages such as corrosion resistance and easy cleaning, making it suitable for storing various materials. An outer lug 212, which mates with the inner support 122, is installed on the outer surface of the column housing 21. The outer lug 212 is fixedly connected to the column housing 21 and secured to the inner support 122 with bolts. This design, with the outer lug 212 and the inner support 122 fastened together by bolts, ensures that the feeding box assembly 2 can be securely installed on the vertical frame 12. This connection method not only guarantees the stability of the connection but also allows for easy and convenient disassembly of the feeding box assembly 2 for maintenance or replacement, requiring only the removal of the bolts. This improves the maintainability and flexibility of the component. The outer lug 212 can be made of the same stainless steel material as the column housing 21, ensuring its strength and corrosion resistance.
[0024] Reference Figure 3 and Figure 4 As shown, the material guide shell 3 includes a disc shell 31 with an open lower end and a side plate 32 connected to the vertical plate 121. The side plate 32 is fixedly installed on both sides of the disc shell 31. The upper surface of the disc shell 31 has a drainage groove 311 corresponding to the lower end of the conical guide shell 22. The disc shell 31 is used to receive the material flowing out of the conical guide shell 22. The design of the open lower end facilitates the material flow direction switching disc assembly 4. The side plate 32 is connected to the vertical plate 121, which securely installs the material guide shell 3 on the vertical frame 12. The drainage groove 311 corresponds to the lower end of the conical guide shell 22, which can accurately guide the material into the material guide shell 3, avoid material leakage, and improve the accuracy of material conveying. The disc shell 31 and the side plate 32 of the material guide shell 3 can be made of aluminum alloy. Aluminum alloy has the advantages of light weight, high strength, and corrosion resistance, which can reduce the weight of the entire component while ensuring its structural strength.
[0025] Reference Figure 4 and Figure 5As shown, the switching disc assembly 4 includes a disc plate 41 and connecting pipe heads 42 corresponding to the discharge trough 311. The connecting pipe heads 42 are evenly installed on the lower end face of the disc plate 41 along the circumferential direction, and are fixedly connected to the disc plate 41. The disc plate 41, as the main structure of the switching disc assembly 4, provides the mounting base for the connecting pipe heads 42. The connecting pipe heads 42, corresponding to the discharge trough 311, can accurately receive the material discharged from the guide shell 3. The evenly installed connecting pipe heads 42 along the circumferential direction enable the switching disc assembly 4 to connect different discharge pipes with the guide shell 3 when rotating, thereby realizing the switching of material feeding. The disc plate 41 can be made of high-strength plastic, such as polyoxymethylene (POM), which has good wear resistance and self-lubricating properties, ensuring the smooth rotation of the switching disc assembly 4. The connecting pipe heads 42 can be made of rubber, which has a certain elasticity, ensuring the sealing of the connection with the discharge pipe.
[0026] Reference Figure 2 and Figure 4 As shown, the heads of the first discharge pipe 5, the second discharge pipe 6, and the third discharge pipe 7 are equipped with insertion pipe heads 51 that connect to the connecting pipe head 42. The insertion pipe head 51 and the connecting pipe head 42 are engaged and fixed. This engagement and fixing method ensures the stability of the connection between the discharge pipe and the switching disc assembly 4, and also facilitates the installation and disassembly of the discharge pipe. This connection method effectively prevents material leakage from the connection point during conveying, improving the sealing and stability of the material conveying process. The discharge pipes can be made of PVC material, which has advantages such as corrosion resistance and low price, making it suitable for material conveying.
[0027] Working Principle: During equipment frame installation, first place the outer ear seat 212 of the feeding box assembly 2 into the inner support seat 122 of the vertical frame 12, and then use bolts to fix the outer ear seat 212 and the inner support seat 122, so that the feeding box assembly 2 is firmly installed between the two sets of vertical frames 12. After installation, check whether the installation position of the feeding box assembly 2 is accurate and ensure that it is in a horizontal state. Align the side plate 32 of the guide shell 3 with the upright plate 121 of the vertical frame 12, and use bolts to fix the side plate 32 and the upright plate 121, so that the guide shell 3 is installed directly below the feeding box assembly 2. At the same time, ensure that the drainage groove 311 of the disc shell 31 is accurately aligned with the lower end of the conical guide shell 22 so that the material can flow smoothly into the guide shell 3. Next, rotate the switching disc assembly 4 into the guide shell 3, and fix the drive motor 30 on the guide shell 3, so that the output shaft of the drive motor 30 is connected to the rotation shaft of the switching disc assembly 4, ensuring that the drive motor 30 can drive the switching disc assembly 4 to rotate normally. Finally, the insertion pipes 51 of the first discharge pipe 5, the second discharge pipe 6, and the third discharge pipe 7 are respectively engaged and fixed with the connecting pipes 42 of the switching plate group 4 to ensure a firm connection and good sealing.
[0028] In use, open the cover 211 of the feeding box assembly 2 and place the material into the column box shell 21. The material flows into the guide shell 3 through the conical guide shell 22 and the discharge channel 311, and then enters the corresponding discharge pipe through the connecting pipe head 42. When it is necessary to switch the discharge pipe, start the drive motor 30 to drive the switching disk assembly 4 to rotate, so that different discharge pipes are connected to the guide shell 3 to realize the switching of material feeding.
[0029] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
