Description

Technical Field

[0001] This application relates to the field of material handling equipment technology, and in particular to a diversion and feeding device. Background Technology

[0002] In many production fields such as food, chemical, and pharmaceutical, it is often necessary to accurately and alternately distribute powdered or granular materials from a single silo to two or more subsequent workstations (such as packaging bags or containers).

[0003] Currently, a common method for diverting material is to use two movable metering cups that alternately move below a fixed discharge port to receive material, weigh or measure it, and then move to their respective stations for discharge. However, in this working mode, the metering cups need to perform large-scale, high-speed reciprocating motions while fully loaded with material.

[0004] Regarding the aforementioned technologies, the inventors discovered certain drawbacks: during the large-scale, high-speed movement of the measuring cup, some material may spill out of the cup due to vibration or inertia. This not only causes material waste and measurement errors but may also contaminate the equipment and working environment, increasing the difficulty and cost of cleaning and maintenance. Utility Model Content

[0005] To address the risks of material leakage and inaccurate metering caused by the large-scale movement of traditional metering cups, this application provides a diversion and feeding device.

[0006] This application provides a diversion and feeding device, which adopts the following technical solution: A diversion and feeding device includes: a frame; a hopper disposed on the frame for receiving material; a cup assembly disposed on the frame and located below the hopper, the cup assembly including a first cup and a second cup; and a drive module connected to the hopper and the cup assembly, for driving the hopper to move horizontally between a first station, a second station, and a third station, and for driving the cup assembly to rotate, thereby opening or closing the first cup and the second cup. Specifically, when the hopper moves to the first station, the hopper is above the first cup, the first cup is closed to receive the material, and the second cup is open to discharge the material; when the hopper moves to the second station, the hopper is between the first cup and the second cup; when the hopper is at the third station, the hopper is above the second cup, the first cup is open to discharge the material, and the second cup is closed to receive the material.

[0007] By adopting the above technical solution, the hopper and the angle cup assembly are independently mounted on the frame. The material flow direction is controlled by driving the hopper to switch positions within a small range, while the two angle cups open and close near their respective positions without requiring large-scale translation. This design significantly reduces the movement range and impact of the fully loaded material components, effectively reducing the risk of material loss and metering errors caused by moving and sprinkling material, and improving the stability, accuracy, and cleanliness of the feeding process.

[0008] Optionally, the diversion and feeding device described in this application further includes a diversion frame disposed between the first and second angle cups, the diversion frame being mounted on the frame; the diversion frame has a blocking surface, a first side wall facing the first angle cup, and a second side wall facing the second angle cup; when the hopper is in the second working position, the feeding guide is blocked by the blocking surface and stops feeding; both the first and second angle cups include angle cup side openings facing the diversion frame, and when the angle cups are in the closed state, the angle cup side openings are respectively fitted and sealed against the first or second side wall. By adopting the above technical solution, the diversion frame provides a clear intermediate stopping position for feeding and provides a reliable sealing surface for the angle cups in the closed state. This ingenious structural design not only realizes the functional switching of the hopper in three working positions but also ensures the sealing performance when the angle cups are closed for material storage, further preventing material leakage.

[0009] Optionally, the edge of the angle cup side opening matches the corresponding side wall surface of the diverter, so that in the closed state, the edge of the angle cup side opening forms a surface contact seal with the side wall surface. By adopting the above technical solution, by making the edge of the angle cup opening form a surface contact seal with the side wall of the diverter, the sealing performance in the closed state is improved, which can suppress the leakage of fine powder from the joint, and help ensure the accuracy of measurement and the cleanliness of the equipment.

[0010] Optionally, the cup assembly further includes a support arm for connecting the cup to the drive module. The drive module drives the support arm to close or open the cup. By adopting the above technical solution, the power transmission path between the cup and the drive module is clarified, and the structure of the support arm makes the application of driving force and the opening and closing of the cup more stable and reliable.

[0011] Optionally, the support arm is equipped with an adjustment module for adjusting the position of the angle cup relative to the diverter frame. By adopting the above technical solution, the introduction of the adjustment module increases the device's debugging flexibility and adaptability. After installation or long-term use, the module can be used to precisely adjust the contact gap and position between the angle cup and the diverter frame to maintain optimal sealing performance.

[0012] Optionally, the cup also has an inclined guide surface, which, when the cup is open, guides the material to be discharged from the side opening of the cup.

[0013] By adopting the above technical solution, the inclined guide surface design utilizes gravity to guide materials smoothly and quickly out of the side opening, ensuring thorough discharge, avoiding material residue, and improving production efficiency.

[0014] Optionally, the lower part of the hopper is configured as a conical section.

[0015] By adopting the above technical solution, the conical structure facilitates the smooth flow of materials to the central discharge pipe under the action of gravity, preventing the accumulation or bridging of materials in the hopper and ensuring the continuity of material discharge.

[0016] Optionally, the feeding guide tube is formed from top to bottom into a conical tube section and a square tube section; the conical tube section is connected to the hopper.

[0017] By adopting the above technical solution, the upper conical tube section plays the role of collecting and accelerating materials, while the lower square tube section can better control the cross-sectional shape of the material flow, making it easier to accurately correspond with the position of subsequent components (such as the flow divider blocking surface or the angle cup), thereby improving the accuracy of material feeding control.

[0018] Optionally, the square tube has a square cross-section, and all four corners of the square cross-section are rounded.

[0019] By adopting the above technical solution to round off sharp corners, the resistance to material flow can be reduced, and damage or wear of the pipe due to stress concentration can be avoided. It also facilitates cleaning.

[0020] Optionally, the diverter rack is provided with a mounting slot, and the diverter rack is detachably mounted on the frame through the mounting slot.

[0021] By adopting the above technical solution, the detachable installation method greatly facilitates the cleaning, maintenance, and replacement of the diversion rack and surrounding area. When handling different materials or requiring deep cleaning, it can be quickly removed, improving the maintainability and ease of use of the equipment.

[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. By switching between the first and second angle cups via a drive hopper, the angle cups only need to open and close in their fixed positions, replacing the traditional method of moving the metering angle cups over a wide area while fully loaded with material. This effectively reduces the risk of material spillage caused by movement and helps improve the accuracy of material metering and the cleanliness of the process. 2. By setting up a flow divider and ensuring that the side opening of the angle cup forms a surface contact seal with the side wall of the flow divider when closed, the sealing performance during material storage is improved, which helps to prevent material leakage from the joint. 3. By setting an adjustment module on the support arm, the relative position of the angle cup and the diverter can be precisely adjusted, improving the reliability of the sealing fit; at the same time, the detachable installation design of the diverter facilitates the cleaning and maintenance of the equipment.

[0034] The following is in conjunction with the appendix Figure 1-10 This application will be described in further detail.

[0035] Reference Figure 1 This application discloses a diversion and feeding device. The diversion and feeding device includes a frame 10, a hopper 20, a feeding guide 30, a cup assembly 40, and a diversion frame 50. A drive module (not shown in the figure) is mounted on the frame 10. Specifically, the hopper 20, the cup assembly 40, and the diversion frame 50 are all mounted on the frame 10. The cup assembly 40 is located below the hopper 20 and includes a first cup 41 and a second cup 42 symmetrically arranged. The diversion frame 50 is located between the first cup 41 and the second cup 42. The lower end of the hopper 20 is connected to the feeding guide 30. The drive module is connected to the hopper 20 and the cup assembly 40. Under the action of the drive module, the hopper 20 can drive the feeding port of the feeding guide 30 to reciprocate above the first cup 41, the diversion frame 50, and the second cup 42. The cup assembly 40 also includes a support arm 43. The first cup 41 and the second cup 42 are connected to the drive module via their respective support arms 43 and can be driven by the drive module to open or close. (See reference...) Figure 1 The hopper 20 is used to temporarily store materials, and its lower part is provided with a conical part 21 for collecting materials and connecting to the upper end of the discharge conduit 30. (Refer to...) Figures 8 to 10 To optimize the flow characteristics of the material, the feed conduit 30 includes a tapered tube section 31 and a square tube section 32 from top to bottom, with the inner walls of the tapered tube section 31 and the square tube section 32 connected in a streamlined manner. The included angle α formed between the outer wall surface of the tapered tube section 31 and the vertical outer wall surface of the square tube section 32 (e.g., ...) Figure 9The included angle (as shown) can range from 150 degrees to 170 degrees. In a preferred embodiment, the included angle α is set to 162 degrees. This angle ensures that the material flows smoothly without generating excessive impact on the lower cup due to excessive flow velocity, thereby significantly improving the stability and accuracy of metering. (Refer to...) Figure 1 , Figure 3 and Figure 7 The diverter 50 has a flat first sidewall 51 on the side facing the first angle cup 41, and a similar flat sidewall 51 on the side facing the second angle cup 42. The upper part of the diverter 50 has a blocking surface 52. When either angle cup needs to receive material, the opening on the side of the corresponding angle cup will fit tightly against the corresponding sidewall, forming a closed cavity.

[0036] In this embodiment, the diversion and feeding device operates in a complete work cycle, with the following specific workflow: the cycle includes three key stations: the first station (feeding to the first angle cup 41), the second station (intermediate cutting), and the third station (feeding to the second angle cup 42). The device moves from the second station to the first station (refer to...). Figure 2 and Figure 3 The cycle begins with the drive module (not shown in the figure) moving the hopper 20 from the second station to the first station, precisely aligning the discharge port of the discharge guide 30 above the first angle cup 41. Simultaneously, the first angle cup 41 is closed, bringing it into contact with the first side wall 51 of the diverter 50 to receive material; at the same time, the second angle cup 42 is opened to discharge the material measured in the previous cycle. The movement from the first station to the second station (see reference...) Figure 4 and Figure 5 After the first angle cup 41 completes metering, the drive module drives the hopper 20 to move from the first station to the second station, which is in the middle position of the device. At this time, the discharge port of the discharge guide 30 is directly opposite the blocking surface 52 at the top of the diverter 50, thereby temporarily blocking the falling material flow and achieving rapid material interception. The material then moves from the second station to the third station (see reference). Figure 6 and Figure 7Next, the drive module drives the hopper 20 to move from the second station to the third station, aligning the discharge port of the discharge guide 30 with the upper part of the second angle cup 42. Simultaneously, the second angle cup 42 is closed to receive new material; at the same time, the first angle cup 41 is opened to discharge the metered material. Returning from the third station to the second station: After the second angle cup 42 completes metering, the drive module drives the hopper 20 back from the third station to the second station, aligning the discharge port of the discharge guide 30 with the blocking surface 52 at the top of the diverter 50 for a second material cut. This step prepares for returning to the first station. Subsequently, the device moves from the second station back to the first station, beginning the next identical work cycle. Thus, a complete, closed work cycle consisting of "second station - first station - second station - third station - second station" is completed.

[0037] In summary, this application utilizes a drive hopper to reciprocate between fixed double-angled cups, and employs a flow divider to intercept material during switching intervals, while simultaneously controlling the opening and closing of the angled cups. In this scheme, the metering components move along a specific trajectory within a small range, which helps reduce material spillage and improves metering accuracy and equipment cleanliness.

[0038] The above description is merely a preferred embodiment of this application and is not intended to limit the scope of protection of this application. Therefore, all equivalent changes made to the structure, shape, and principle of this application should be covered within the scope of protection of this application.
