Description

Technical Field

[0001] This application relates to the field of batching equipment technology, and in particular to a batching disc baffle device. Background Technology

[0002] As a core piece of equipment in raw material batching systems in industries such as metallurgy, chemicals, and building materials, the batching disc functions to uniformly transport materials to downstream processes through its rotational motion, achieving quantitative batching control. A typical batching disc structure includes components such as the disc body, drive unit, scraper, and internal baffles. Among these, the baffles are key components for maintaining stable material transport, primarily functioning to prevent material from spreading to non-conveying areas, avoiding spillage or accumulation at the disc's edge, thereby ensuring efficient equipment operation.

[0003] Currently, during the operation of the batching disc, the material on the disc surface continuously rubs against the internal baffle plate, causing the baffle plate to wear easily and the gap between it and the disc to widen. This results in the material being carried to the back of the baffle plate, and because it is inside the disc cover, it is not easily detected during inspection. This can easily cause material to accumulate on the disc, making the disc heavier and eventually causing the entire disc to seize up, affecting the normal operation of the batching process. Therefore, this issue needs to be addressed. Utility Model Content

[0004] To address the problem of material accumulation on the batching disc being difficult to detect, this application provides a material blocking device for the batching disc.

[0005] The batching disc retaining device provided in this application adopts the following technical solution:

[0006] A material-blocking device for a dispensing disc includes a material-blocking mechanism arranged on an internal support of the disc. The material-blocking mechanism includes a material-blocking plate and a material-blocking frame. The material-blocking plate is connected to the side of the material-blocking frame facing the disc. The material-blocking frame is slidably connected to the internal support of the disc. A lifting component for raising and lowering the material-blocking frame is provided on the internal support of the disc. A sensor switch for detecting material leakage is also provided on the internal support of the disc, and the sensor switch is arranged on the side of the internal support of the disc away from the disc feed inlet.

[0007] During the operation of the batching disc, the material on the disc surface continuously rubs against the internal baffle plate, causing the baffle plate to wear easily and the gap between it and the disc to widen. This results in material being carried to the back of the baffle plate, and because it is inside the disc cover, it is not easily detected during inspection. This can easily cause material accumulation on the disc, making the disc heavier and eventually causing the entire disc to seize up, affecting the normal operation of the batching process. By adopting the above technical solution, including a baffle mechanism, the baffle mechanism is installed on the internal support of the disc. The baffle mechanism includes a baffle plate and a baffle frame. A lifting mechanism is installed between the baffle frame and the internal support of the disc. The baffle plate is installed on the baffle frame, and a sensor switch is installed on the back of the internal support of the disc.

[0008] When the baffle plate wears during the operation of the disc, the material on the disc surface is carried into the area behind the baffle plate by centrifugal force due to the increased gap between the baffle plate and the disc surface. At this time, the inductive switch detects the leakage signal (such as material accumulation touching the switch or infrared / laser blocking signal). The inductive switch transmits the leakage signal to the control system, issues an alarm, and stops the operation of the disc main motor to prevent further leakage and accumulation. The lifting component is activated to drive the baffle frame to slide along the internal support of the disc, adjust the vertical position of the baffle plate so that it is close to the disc surface again, and reduce the gap to the set safe range. The material accumulated on the back of the baffle plate is manually cleaned. After the adjustment is completed, the inductive switch checks again whether there is still leakage on the back of the baffle plate. If no leakage signal is detected, the disc operation is resumed.

[0009] By incorporating a material-blocking mechanism, lifting components, and inductive switches, the system effectively solves the problems of material leakage, accumulation, and disc jamming caused by increased gaps due to wear of the material-blocking plates during the operation of the batching disc. The inductive switches can detect material leakage signals on the back of the material-blocking plates in real time, preventing further leakage and accumulation. Simultaneously, the lifting components adjust the position of the material-blocking plates to bring them closer to the disc surface, reducing the gap to a safe range. After manual cleaning of accumulated material, operation can resume. Timely intervention and position compensation prevent disc jamming caused by increased material accumulation, ensuring continuous and stable operation of the batching system, reducing the difficulty of manual inspection of material leakage inside the disc cover, and improving equipment maintenance efficiency.

[0010] Optionally, the lifting assembly includes a lifting screw, a threaded assembly, and a drive component for driving the lifting screw to rotate. The lifting screw is rotatably connected to the internal support of the disc. The lifting screw is arranged along the height direction of the retaining frame. The threaded assembly is arranged on the back of the retaining frame and is threadedly connected to the lifting screw.

[0011] By adopting the above technical solution, the lifting assembly includes a lifting screw, a threaded assembly, and a driving component. When the lifting assembly is started, the driving component drives the lifting screw to rotate, and the threaded assembly drives the baffle frame to slide along the internal support of the disc, so that the baffle plate is brought back close to the disc surface, reducing the gap to the initial safe range. Through the setting of the lifting assembly, the baffle frame can be quickly and accurately adjusted, which can promptly compensate for the gap caused by the wear of the baffle plate, effectively avoid material leakage and back accumulation, and ensure the continuous and stable operation of the batching system.

[0012] Optionally, a guide rail component is provided between the material stop frame and the internal support of the disc. The guide rail component includes two guide rails and two guide grooves. The two guide rails are vertically fixed on the internal support of the disc and parallel to the lifting screw. The two guide grooves are fixed on the material stop frame and slide with the two guide rails respectively. The two guide rails are distributed on both sides of the lifting screw.

[0013] By adopting the above technical solution, the guide rail component is installed between the baffle frame and the internal support of the disc. The guide rail component includes two guide rails and two guide grooves. The guide rails and guide grooves guide the baffle frame, effectively constrain the movement direction of the baffle frame, ensure that it slides only in the vertical direction, reduce the offset or shaking caused by uneven force during lifting, and improve the accuracy of baffle plate position adjustment.

[0014] Optionally, the internal support of the disc is provided with two bearing seats, which are arranged at both ends of the lifting screw along its length, and the lifting screw is rotatably connected to the two bearing seats.

[0015] By adopting the above technical solution, the lifting screw is installed on the internal support of the disc through the bearing seat; the bearing seat provides support for the lifting screw, effectively dispersing the radial and axial loads generated when the screw rotates, reducing bending deformation or eccentric wear caused by uneven force on the screw, and ensuring the long-term stability of the lifting screw.

[0016] Optionally, the drive unit includes a turntable connected to the top of the lifting screw.

[0017] By adopting the above technical solution, the driving component includes a turntable, which is connected to the top of the lifting screw. By setting the turntable, the lever arm length during operation is increased, making it easier to manually rotate the lifting screw.

[0018] Optionally, bolts for fixing are provided between the baffle plate and the baffle frame, and mounting holes for the bolts to pass through are provided on the baffle plate.

[0019] By adopting the above technical solution, bolts are installed between the baffle plate and the baffle frame, and mounting holes are opened through the baffle plate. Through the setting of mounting holes and bolts, the baffle plate can be quickly disassembled and securely connected, ensuring that the baffle plate remains stable and does not deviate during the high-speed operation of the disc. At the same time, the bolt connection method is simple in structure and easy to operate, making it convenient for the installation or replacement of the baffle plate.

[0020] Optionally, the top of the baffle frame is flush with the top of the baffle plate, the bottom of the baffle frame is higher than the bottom of the baffle plate, and the distance between the bottoms of the two is 30-50mm.

[0021] By adopting the above technical solution, the top of the baffle frame is flush with the top of the baffle plate, and the bottom of the baffle frame is higher than the bottom of the baffle plate, with a distance of 30-50mm between the bottoms of the two. Through the setting of the positions of the baffle frame and the baffle plate, this distance design allows the bottom of the baffle plate to contact the disc surface first, which not only ensures the initial baffle effect, but also avoids wear or scratches caused by the frame directly rubbing against the disc surface, reducing equipment wear. In addition, when the baffle plate wears to its limit, only the baffle plate needs to be replaced without adjusting the position of the frame, simplifying the maintenance process.

[0022] Optionally, the inductive switch is a limit switch, with its sensing rod contacting the surface of the disc and a preset maximum travel threshold. When the thickness of the leaked material accumulation exceeds the threshold, an alarm signal is triggered.

[0023] By adopting the above technical solution, the inductive switch is a limit switch; by selecting the inductive switch, accurate monitoring and rapid response to leakage and accumulation of material are achieved. The limit switch has a simple structure and high reliability. Its mechanical contact design can directly sense the physical pressure generated by the accumulation of material, thereby improving the leakage detection accuracy and response speed of the material blocking device.

[0024] In summary, this application includes at least one of the following beneficial technical effects:

[0025] 1. By setting up a material blocking mechanism, lifting components, and inductive switches, the system effectively solves the problems of material leakage, material accumulation, and disc jamming caused by the increased gap due to wear of the material blocking plate during the operation of the batching disc. The inductive switches can detect material leakage signals on the back of the material blocking plate in real time to prevent further material leakage and accumulation. At the same time, the lifting components adjust the position of the material blocking plate to bring it closer to the disc surface, reducing the gap to a safe range. After manual cleaning of the accumulated material, operation can be resumed. Timely intervention and position compensation prevent disc jamming caused by the increased weight of accumulated material, ensuring the continuous and stable operation of the batching system, reducing the difficulty of manual inspection of material leakage inside the disc cover, and improving equipment maintenance efficiency.

[0026] 2. The lifting components enable rapid and precise adjustment of the baffle frame, timely compensation for gaps caused by baffle wear, effective prevention of material leakage and back accumulation, and ensure the continuous and stable operation of the batching system.

[0027] 3. By setting the positions of the baffle frame and the baffle plate, this spacing design ensures that the bottom of the baffle plate contacts the disc surface first, which not only guarantees the initial baffle effect but also avoids wear or scratches caused by the frame directly rubbing against the disc surface, reducing equipment wear. In addition, when the baffle plate wears to its limit, only the baffle plate needs to be replaced without adjusting the frame position, simplifying the maintenance process.

Detailed Implementation

[0033] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0034] This application discloses a material-stopping device for a dispensing disc. (Refer to...) Figure 1 and Figure 2 The feeding disc baffle device includes a baffle mechanism 2. In this embodiment, the baffle mechanism 2 is installed on the internal support 1 of the disc. The baffle mechanism 2 includes a baffle plate 21 and a baffle frame 22. The baffle plate 21 is connected to the baffle frame 22 on the side facing the disc feed port.

[0035] Reference Figure 1 and Figure 3 Bolts for fixing are installed between the baffle plate 21 and the baffle frame 22. The baffle plate 21 has through holes 8 for the bolts to pass through. In this embodiment, there are multiple sets of bolts, which are located at each corner of the baffle plate 21. This enables the baffle plate 21 to be quickly disassembled and securely connected, ensuring that the baffle plate 21 remains stable and does not deviate during the high-speed operation of the disc. At the same time, the bolt connection method is simple in structure and easy to operate, making it convenient for the installation or replacement of the baffle plate 21.

[0036] Reference Figure 1 In this embodiment, the top of the baffle frame 22 is flush with the top of the baffle plate 21, and the bottom of the baffle frame 22 is higher than the bottom of the baffle plate 21. The distance between the bottoms of the two is 30-50mm, preferably 50mm. This distance design ensures that the bottom of the baffle plate 21 contacts the disc surface first, which not only ensures the initial baffle effect but also avoids wear or scratches caused by direct friction between the frame and the disc surface, reducing equipment wear. In addition, when the baffle plate 21 is worn to its limit, only the baffle plate 21 needs to be replaced without adjusting the frame position, simplifying the maintenance process.

[0037] Reference Figure 1 and Figure 4 The baffle frame 22 is slidably connected to the internal support 1 of the disc. A guide rail component 5 is installed between the baffle frame 22 and the internal support 1 of the disc. The guide rail component 5 includes two guide rails 51 and two guide grooves 52. The two guide rails 51 are vertically fixed to the internal support 1 of the disc. The two guide grooves 52 are fixedly installed on the baffle frame 22. The two guide grooves 52 are slidably engaged with the two guide rails 51 respectively to guide the baffle frame 22, effectively constrain the movement direction of the baffle frame 22, ensure that it slides only in the vertical direction, and reduce the offset or shaking caused by uneven force during the lifting process.

[0038] Reference Figure 1 and Figure 2 A lifting assembly 3 is installed on the internal support 1 of the disc. The lifting assembly 3 is used to drive the lifting of the baffle frame 22. The lifting assembly 3 includes a lifting screw 31, a threaded assembly 32, and a driving component. The lifting screw 31 is vertically arranged on the internal support 1 of the disc, and two guide rails 51 are distributed on both sides of the lifting screw 31. Two bearing seats 6 are installed on the internal support 1 of the disc. The two bearing seats 6 are arranged at both ends of the length direction of the lifting screw 31. The lifting screw 31 is rotatably connected to the two bearing seats 6 through bearings. This is used to support the lifting screw 31, effectively disperse the radial and axial loads generated when the screw rotates, reduce the bending deformation or eccentric wear of the screw due to uneven force, and ensure the long-term stability of the lifting screw 31.

[0039] Reference Figure 1 and Figure 3 The threaded assembly 32 is installed on the back of the retaining frame 22. The threaded assembly 32 is threadedly connected to the lifting screw 31. There can be multiple threaded assemblies 32. At the same time, the driving component is used to drive the lifting screw 31 to rotate. The driving component includes a turntable 7, which is connected to the top of the lifting screw 31. In this embodiment, the turntable 7 can be controlled by a motor or manually. The turntable 7 increases the lever arm length during operation, making it easier to manually rotate the lifting screw 31.

[0040] Reference Figure 1 An inductive switch 4 is installed on the internal support 1 of the disc. The inductive switch 4 is located on the side of the internal support 1 facing away from the disc feed port. The inductive switch 4 can be a limit switch. Its sensing rod contacts the disc surface and is preset with a maximum travel threshold. When the thickness of the leaked material accumulation exceeds the threshold, an alarm signal is triggered. In this embodiment, the inductive switch 4 is connected to the on-site alarm light and also to the remote alarm signal of the computer. When the on-site alarm light flashes, the on-site inspectors can promptly find that the disc needs to adjust the position of the baffle 21 and make a quick adjustment to ensure normal production. If the on-site inspectors are inspecting elsewhere, the remote central control personnel can also immediately notify the on-site personnel to make adjustments on-site when they find the remote alarm signal on the computer interface.

[0041] The implementation principle of the batching disc baffle device in this application embodiment is as follows: When the baffle plate 21 wears during the operation of the disc, the material on the disc surface is carried into the back area of ​​the baffle plate 21 by the centrifugal force due to the increased gap between the baffle plate 21 and the disc surface. At this time, the induction switch 4 detects the leakage signal (such as material accumulation touching the switch or infrared / laser blocking signal). The induction switch 4 transmits the leakage signal to the control system, issues an alarm, and stops the operation of the disc main motor to prevent further leakage and accumulation. The lifting component 3 is started to drive the baffle frame 22 to slide along the internal support 1 of the disc, adjust the vertical position of the baffle plate 21 so that it is close to the disc surface again, and reduce the gap to the set safe range. The material accumulated on the back of the baffle plate 21 is manually cleaned. After the adjustment is completed, the induction switch 4 checks again whether there is still leakage on the back of the baffle plate 21. If no leakage signal is detected, the disc operation is resumed.

[0042] By setting up the material blocking mechanism 2, the lifting component 3, and the inductive switch 4, the problems of material leakage, material accumulation, and disc jamming caused by the increased gap due to wear of the material blocking plate 21 during the operation of the batching disc are effectively solved. The inductive switch 4 can detect the material leakage signal on the back of the material blocking plate 21 in real time to prevent further material leakage and accumulation. At the same time, the lifting component 3 adjusts the position of the material blocking plate 21 so that it is close to the disc surface again, reducing the gap to a safe range. After manual cleaning of the accumulated material, operation is restored. Timely intervention and position compensation avoid the disc jamming failure caused by the increased weight of the accumulated material, ensuring the continuous and stable operation of the batching system, reducing the difficulty of manual inspection of material leakage inside the disc cover, and improving equipment maintenance efficiency.

[0043] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
