Description

Technical Field

[0001] This utility model relates to the field of material dispensing devices, and in particular to material dispensing devices. Background Technology

[0002] In industries such as metallurgy and building materials, conveyor belts are core equipment for continuous material transport. They enable precise classification and quantitative storage of materials according to their type, specifications, and usage, which is a key link in ensuring stable subsequent production.

[0003] Currently, conveyors with multiple conveyor belts or mobile conveyor belts are commonly used for sorting and unloading materials. Conveyors with multiple fixed conveyor belts are complex in structure, have high procurement and construction costs, and occupy a large space. Conveyors with mobile conveyor belts require additional moving drive components and guiding components, resulting in numerous parts, frequent failures, and high maintenance costs. Furthermore, both types of conveyors require manual on-site monitoring, which is not only inefficient but also prone to sorting errors due to human error, affecting subsequent production processes.

[0004] Therefore, a material distribution device is urgently needed to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a material distribution device that eliminates the need for multiple conveyor belts or moving components, thereby reducing costs and malfunctions, minimizing manual monitoring, improving material distribution accuracy and efficiency, and ensuring stable subsequent production.

The conveyor belt is arranged on the frame and extends horizontally to hold and convey the material. The first hopper and the second hopper are respectively located below the first material distribution mechanism and the second material distribution mechanism.

[0008] The first thickness gauge is used to measure the thickness H1 of the material passing through its detection area on the conveyor belt. The minimum distance between the first guide surface of the first material distribution mechanism and the surface of the conveyor belt is the first material passage gap H2. When H1 > H2, the first blocking surface of the first material distribution mechanism guides the material with a thickness exceeding H2 to fall into the first hopper. When H1 ≤ H2, the material passes through the first material passage gap H2 along the first guide surface and continues to be conveyed to the detection area of ​​the second thickness gauge.

[0009] The second thickness gauge is used to measure the thickness H3 of the material passing through its detection area on the conveyor belt. The minimum distance between the second guide surface of the second material distribution mechanism and the surface of the conveyor belt is the second material passage gap H4. When H3 > H4, the second blocking surface of the second material distribution mechanism guides the material with a thickness exceeding H4 to fall into the second hopper. When H3 ≤ H4, the material passes through the second material passage gap H4 along the second guide surface and continues to be conveyed.

[0051] This embodiment discloses a material dispensing device, such as... Figures 1-6As shown, the material distribution device includes a frame 1, a conveyor belt 2, a first hopper, a second hopper, a first thickness gauge 31, a first distribution mechanism 4, a second thickness gauge 32, and a second distribution mechanism 5, which are sequentially arranged on the frame 1 along the material 100 conveying direction. The conveyor belt 2 is arranged on the frame 1 and extends horizontally to hold and convey the material 100. The first hopper and the second hopper are respectively located below the first distribution mechanism 4 and the second distribution mechanism 5. The first thickness gauge 31 is used to measure the thickness H1 of the material 100 passing through its detection area on the conveyor belt 2. The minimum distance between the first guide surface 421 of the first distribution mechanism 4 and the surface of the conveyor belt 2 is the first material passage gap H2. When H1 > H2, the first blocking surface 422 of the first distribution mechanism 4 guides the material 100 with a thickness exceeding H2 to fall into the first hopper. When H1 ≤ H2, the material 100 passes through the first material passage gap H2 along the first guide surface 421 and continues to be conveyed to the detection area of ​​the second thickness gauge 32. The second thickness gauge 32 is used to measure the thickness H3 of the material 100 passing through its detection area on the conveyor belt 2. The minimum distance between the second guide surface 521 of the second material distribution mechanism 5 and the surface of the conveyor belt 2 is the second material passage gap H4. When H3 > H4, the second blocking surface 522 of the second material distribution mechanism 5 guides the material 100 with a thickness exceeding H4 to fall into the second hopper. When H3 ≤ H4, the material 100 passes through the second material passage gap H4 along the second guide surface 521 and continues to be conveyed.

[0052] When the material distribution device is working, the material 100 is horizontally conveyed by the conveyor belt 2 on the frame 1. The thickness H1 of the material 100 is measured by the first thickness gauge 31. The minimum distance between the first guide surface 421 of the first distribution mechanism 4 and the surface of the conveyor belt 2 is the first material passage gap H2. If H1 > H2, the material 100 is guided by the first blocking surface 422 to fall into the first hopper below. If H1 ≤ H2, the material 100 continues to be conveyed along the first guide surface 421 through the first material passage gap H2. The thickness H3 is then measured by the second thickness gauge 32. The minimum distance between the second guide surface 521 of the second distribution mechanism 5 and the surface of the conveyor belt 2 is the second material passage gap H4. If H3 > H4, the material 100 is guided by the second blocking surface 522 to fall into the second hopper below. If H3 ≤ H4, the material 100 continues to be conveyed along the second guide surface 521 through the second material passage gap H4. This material sorting device relies on a single conveyor belt 2 to achieve multi-point automatic unloading, eliminating the need for multiple conveyor belts 2 or moving components, reducing costs and malfunctions, minimizing manual monitoring, and improving the accuracy and efficiency of material sorting. It can separate materials according to quantity as needed and pick up 100% of the materials, ensuring the stability of subsequent production processes.

[0053] In this embodiment, both the first thickness gauge 31 and the second thickness gauge 32 are ultrasonic sensors. The first thickness gauge 31 uses an ultrasonic sensor, which can accurately measure the thickness H1 without contacting the material 100, avoiding damage to the material 100. It is compatible with the continuous conveying rhythm of the conveyor belt 2 and provides reliable data for the first material distribution mechanism 4 to adjust the first material passage gap H2, thereby improving the accuracy of material distribution and operational stability. The second thickness gauge 32 uses an ultrasonic sensor, which can accurately measure the thickness H3 of the material 100 without contact, without damaging the material 100. It is compatible with the continuous conveying rhythm of the conveyor belt 2 and provides a reliable basis for the second material distribution mechanism 5 to adjust the second material passage gap H4, thereby enhancing the accuracy of material distribution and the operational stability of the material distribution device.

[0054] In other embodiments, the first thickness gauge 31 and the second thickness gauge 32 can also be photoelectric sensors, which can non-contactly measure the thickness H1 and H3 of the material 100. They have a fast response speed, are adapted to the high-speed conveying rhythm of the conveyor belt 2, and have stable measurement accuracy. They provide reliable data for adjusting the first material passing gap H2 and the second material passing gap H4, ensuring efficient and accurate material distribution.

[0055] like Figure 1 and Figure 3 As shown, the first material distribution mechanism 4 includes a first rocker arm 40, a first pin, a first drive assembly 41, and a first stop 42. One end of the first rocker arm 40 is rotatably connected to the frame 1 via the first pin, and the other end is connected to the first stop 42. The first drive assembly 41 drives the first stop 42 to rotate relative to the frame 1 around the first pin, so that the first material passage gap H2 between the first guide surface 421 on the first stop 42 and the surface of the conveyor belt 2 is adjustable. The first material distribution mechanism 4 drives the first stop 42 to rotate around the first pin via the first drive assembly 41, so that the first material passage gap H2 between the first guide surface 421 and the surface of the conveyor belt 2 is adjustable, which can adapt to the material distribution needs of materials 100 of different thicknesses, improve the versatility and flexibility of the material distribution device, and enhance the material distribution accuracy in conjunction with the first thickness gauge 31.

[0056] It is worth noting that initially, the first guide surface 421 is in contact with and parallel to the surface of the conveyor belt 2. When the first stop 42 rotates relative to the frame 1 around the first pin, the first stop 42 is raised vertically. The first guide surface 421 and the surface of the conveyor belt 2 form a preset angle. The minimum distance between the first guide surface 421 and the surface of the conveyor belt 2 is the first material passage gap H2.

[0057] like Figure 1As shown, the second material distribution mechanism 5 includes a second rocker arm 50, a second pin, a second drive assembly 51, and a second stop 52. One end of the second rocker arm 50 is rotatably connected to the frame 1 via the second pin, and the other end is connected to the second stop 52. The second drive assembly 51 drives the second stop 52 to rotate relative to the frame 1 around the second pin, so that the second material passage gap H4 between the second guide surface 521 on the second stop 52 and the surface of the conveyor belt 2 is adjustable. The second material distribution mechanism 5 drives the second stop 52 to rotate around the second pin via the second drive assembly 51, making the second material passage gap H4 between the second guide surface 521 and the surface of the conveyor belt 2 adjustable. This allows it to adapt to the material distribution needs of materials 100 of different thicknesses, improving the applicability and adjustment flexibility of the material distribution device. Combined with the second thickness gauge 32, it further improves the material distribution accuracy.

[0058] It is worth noting that initially, the second guide surface 521 is in contact with and parallel to the surface of the conveyor belt 2. When the second stop 52 rotates relative to the frame 1 around the second pin, the second stop 52 is raised vertically. The second guide surface 521 and the surface of the conveyor belt 2 form a preset angle. The minimum distance between the second guide surface 521 and the surface of the conveyor belt 2 is the second material passage gap H4.

[0059] like Figures 2-6 As shown, both the first stop 42 and the second stop 52 are arrow-shaped structures constructed from two plates whose edges intersect and form an acute angle. The guide tip of the arrow structure points in the opposite direction to the conveying direction of the material 100. In the first stop 42, the surface of the guide tip facing the conveying direction of the material 100 is the first blocking surface 422, and the two sidewalls on the two plates facing the surface of the conveyor belt 2 together form a V-shaped first guide surface 421. In the second stop 52, the surface of the guide tip facing the conveying direction of the material 100 is the second blocking surface 522, and the two sidewalls on the two plates facing the surface of the conveyor belt 2 together form a V-shaped second guide surface 521. The arrow-shaped first blocking surface 422 and second blocking surface 522 can accurately intercept the material 100 and guide the material 100 to fall, improving the smoothness and accuracy of material distribution and adapting to the continuous conveying rhythm of the conveyor belt 2. The V-shaped first guide surface 421 and V-shaped second guide surface 521 can smoothly guide the material 100 of the appropriate thickness to pass through.

[0060] like Figures 2-4As shown, the first stop 42 adopts an arrow structure with its edges intersecting at an acute angle, and the guide tip points in the opposite direction to the material 100 conveying direction. On the one hand, when H1 > H2, the acute angle design of the arrow structure allows the first blocking surface 422 to naturally guide the material 100 into the first hopper below by means of the tilt angle, which not only ensures the accuracy of interception, but also improves the smoothness of material guidance and enhances the stability of material distribution. On the other hand, the V-shaped first guide surface 421 can smoothly guide the material 100 with a thickness that meets the condition H1 ≤ H2 to pass smoothly through the first material passage gap H2, avoiding conveying jams.

[0061] like Figures 5-6 As shown, the second stop 52 adopts an arrow structure with its edges intersecting at an acute angle, and the guide tip points in the opposite direction to the material 100 conveying direction. On the one hand, when H3 > H4, the acute angle design of the arrow structure allows the second blocking surface 522 to naturally guide the material 100 into the lower second hopper by means of the tilt angle, which not only ensures the accuracy of interception, but also improves the smoothness of material guidance and enhances the stability of material distribution. On the other hand, the V-shaped second guide surface 521 can smoothly guide the material 100 with a thickness that meets the condition H3 ≤ H4 to pass smoothly through the second material passage gap H4, avoiding conveying jams.

[0062] Optionally, the acute angle can be 30 degrees, 45 degrees, 60 degrees, 75 degrees, etc., without specific limitations.

[0063] like Figure 2 As shown, the material distribution device also includes a connecting rod 61 and a pressure sensor 62. The two ends of the connecting rod 61 are connected to the two plates of the arrow structure, respectively. When the material 100 presses against the surface of the guide tip, the connecting rod 61 deforms under pressure. The pressure sensor 62 is mounted on the connecting rod 61 to detect the magnitude of the pressure. The pressure sensor 62 can provide real-time feedback on the interaction status between the material 100 and the first stop 42, and between the material 100 and the second stop 52, assisting in determining whether the material distribution is smooth, reducing jamming problems, and ensuring the stable and efficient distribution of materials by the material distribution device.

[0064] like Figures 1-3 As shown, the first drive assembly 41 includes a first hydraulic cylinder 411. A first piston rod within the first hydraulic cylinder 411 can reciprocate relative to the first hydraulic cylinder 411. The first hydraulic cylinder 411 is connected to the frame 1, and the first piston rod is connected to a first stop member 42. The first piston rod forms a first preset angle with the horizontal direction. The movement of the first piston rod can drive the first stop member 42 to rotate relative to the frame 1 around a first pin. This allows for stable adjustment of the first material passage gap H2, strong driving force, and precise control, adapting to the material distribution needs of different materials 100 and improving the adjustment reliability of the first material distribution mechanism 4.

[0065] like Figure 1 , Figure 5 and Figure 6As shown, the second drive assembly 51 includes a second hydraulic cylinder 511. A second piston rod within the second hydraulic cylinder 511 can reciprocate relative to the cylinder. The second hydraulic cylinder 511 is connected to the frame 1, and the second piston rod is connected to a second stop 52. The second piston rod forms a second preset angle with the horizontal direction. The movement of the second piston rod can drive the second stop 52 to rotate relative to the frame 1 around a second pin. This allows for stable adjustment of the second material passage gap H4, providing strong driving force and precise control, adapting to the material distribution needs of different materials 100, and improving the adjustment reliability of the second material distribution mechanism 5.

[0066] like Figures 1-3 As shown, the first drive assembly 41 also includes a first motor 412, a first hydraulic pump, and a first hydraulic pipeline. The first motor 412 is connected to the first hydraulic pump and can drive the first hydraulic pump to generate high-pressure hydraulic oil. The high-pressure hydraulic oil is delivered to the rodless or rod chamber of the first hydraulic cylinder 411 through the first hydraulic pipeline to drive the first piston rod to reciprocate relative to the first hydraulic cylinder 411. Precisely driving the movement of the first piston rod provides stable power for the rotation of the first stop 42, ensuring efficient and controllable adjustment of the first material passage gap H2 and improving the working stability of the first material distribution mechanism 4.

[0067] like Figure 1 , Figure 5 and Figure 6 As shown, the second drive assembly 51 also includes a second motor 512, a second hydraulic pump, and a second hydraulic pipeline. The second motor 512 is connected to the second hydraulic pump, and can drive the second hydraulic pump to generate high-pressure hydraulic oil. The high-pressure hydraulic oil is delivered through the second hydraulic pipeline to the rodless or rod-side chamber of the second hydraulic cylinder 511 to drive the second piston rod to reciprocate relative to the second hydraulic cylinder 511. Precisely driving the movement of the second piston rod provides stable power for the rotation of the second stop 52, ensuring efficient and controllable adjustment of the second material passage gap H4, and improving the working stability of the second material distribution mechanism 5.

[0068] like Figure 1 As shown, the material distribution device also includes a control mechanism 10, which is communicatively connected to the first motor 412 and the second motor 512. The control mechanism 10 is used to independently or in conjunction with preset parameters to control the first motor 412 and the second motor 512 to adjust the first material passing gap H2 and the second material passing gap H4. The control mechanism 10 independently or in conjunction with preset parameters controls the first motor 412 and the second motor 512 to precisely adjust the first material passing gap H2 and the second material passing gap H4, adapting to diverse material distribution needs, improving operational convenience, ensuring the efficient and coordinated operation of the first material distribution mechanism 4 and the second material distribution mechanism 5, enhancing the automation level of the material distribution device, reducing manual monitoring, improving material distribution accuracy and efficiency, and ensuring stable subsequent production.

[0069] like Figure 1 As shown, the material distribution device also includes a first support mechanism 7 and a second support mechanism 8. The first support mechanism 7 is located on the lower side of the conveyor belt 2 in the corresponding area of ​​the first material distribution mechanism 4, and is used to support the conveyor belt 2 in the corresponding area. The second support mechanism 8 is located on the lower side of the conveyor belt 2 in the corresponding area of ​​the second material distribution mechanism 5, and is used to support the conveyor belt 2 in the corresponding area. This effectively prevents the conveyor belt 2 from deforming when the first stop 42 and the second stop 52 are pressed down, ensures the stability of the first material passage gap H2 and the second material passage gap H4, ensures accurate material distribution, and maintains the stability of the material 100 conveyed by the conveyor belt 2.

[0070] like Figure 1 As shown, the first support mechanism 7 includes a first idler roller group 71 and a third drive assembly 72. The third drive assembly 72 drives the first idler roller group 71 to move to the underside of the conveyor belt 2 in the area corresponding to the first material distribution mechanism 4, and supports the conveyor belt 2 in the corresponding area. The third drive assembly 72 can drive the first idler roller group 71 to move to the underside of the conveyor belt 2 in the area corresponding to the first material distribution mechanism 4 and provide stable support as needed, avoid deformation of the conveyor belt 2, ensure the accuracy of the first material passing gap H2, improve the reliability of material distribution, and adapt to the support requirements under different working conditions.

[0071] Specifically, the third drive assembly 72 includes a third hydraulic cylinder 721 and a third motor 722. The third motor 722 is connected to the hydraulic pump and drives the pump to generate high-pressure hydraulic oil. The high-pressure hydraulic oil is delivered to the rodless or rod chamber of the third hydraulic cylinder 721 through a hydraulic pipeline, driving the third piston rod to reciprocate relative to the third hydraulic cylinder 721. The third hydraulic cylinder 721 is connected to the frame 1, and the third piston rod is connected to the first idler roller group 71. The extension and retraction of the third piston rod drives the first idler roller group 71 to move horizontally to the lower side of the conveyor belt 2 in the corresponding area of ​​the first material distribution mechanism 4, forming a stable support. This hydraulic drive method is powerful and precisely adjustable, and can flexibly adjust the support position and force of the first idler roller group 71 according to the working state of the first material distribution mechanism 4, effectively preventing the conveyor belt 2 from deforming due to force, ensuring the stability of the first material passage gap H2, and thus improving the working reliability and material distribution accuracy of the material distribution device.

[0072] like Figure 1 As shown, the second support mechanism 8 includes a second idler roller group 81 and a fourth drive assembly 82. The fourth drive assembly 82 drives the second idler roller group 81 to move to the underside of the conveyor belt 2 in the area corresponding to the second material distribution mechanism 5, and supports the conveyor belt 2 in the corresponding area. The fourth drive assembly 82 can drive the second idler roller group 81 to move to the underside of the conveyor belt 2 in the area corresponding to the second material distribution mechanism 5 and provide stable support as needed, avoid deformation of the conveyor belt 2, ensure the accuracy of the second material passing gap H4, improve the reliability of material distribution, and adapt to the support requirements under different working conditions.

[0073] Specifically, the fourth drive assembly 82 includes a fourth hydraulic cylinder 821 and a fourth motor 822. The fourth motor 822 is connected to the hydraulic pump and drives the pump to generate high-pressure hydraulic oil. The high-pressure hydraulic oil is delivered to the rodless or rod chamber of the fourth hydraulic cylinder 821 through a hydraulic pipeline, driving the fourth piston rod to reciprocate relative to the fourth hydraulic cylinder 821. The fourth hydraulic cylinder 821 is connected to the frame 1, and the fourth piston rod is connected to the second idler roller group 81. The extension and retraction of the fourth piston rod drives the second idler roller group 81 to move horizontally to the lower side of the conveyor belt 2 in the corresponding area of ​​the second material distribution mechanism 5, forming a stable support. This hydraulic drive method is powerful and precisely adjustable, and can flexibly adjust the support position and force of the second idler roller group 81 according to the working state of the second material distribution mechanism 5, effectively preventing the conveyor belt 2 from deforming due to force, ensuring the stability of the second material passage gap H4, and thus improving the working reliability and material distribution accuracy of the material distribution device.

[0074] It is worth noting that both the first idler group 71 and the second idler group 81 include multiple rotating rollers and a parallelogram bracket. The multiple rotating rollers are rotatably mounted on the parallelogram bracket facing the same side of the conveyor belt 2. The parallelogram bracket of the first idler group 71 is connected to a third piston rod, and the parallelogram bracket of the second idler group 81 is connected to a fourth piston rod. The parallelogram bracket is deformable to drive the multiple rotating rollers to move vertically towards or away from the conveyor belt 2. The multiple rotating rollers reduce friction with the conveyor belt 2, making the conveyor belt 2 run more smoothly. Simultaneously, they distribute the load, preventing excessive localized stress that could damage the conveyor belt 2 and ensuring stable support. The parallelogram bracket is flexible and deformable, allowing the rotating rollers to move precisely in the vertical direction, ensuring adjustment accuracy, adapting to different support requirements, and improving the flexibility of the mechanism.

[0075] like Figures 1-3 As shown, the first support mechanism 7 also includes a first position detection element 73, which is used to detect the position of the first idler group 71. The first position detection element 73 can detect the position of the first idler group 71 and can provide real-time feedback on whether the first idler group 71 is in the support position under the conveyor belt 2 in the corresponding area of ​​the first material distribution mechanism 4, ensuring that the support is in place, ensuring the stability of the first material passage gap H2, and improving the reliability of the support and the accuracy of material distribution.

[0076] like Figure 1 , Figure 5 and Figure 6 As shown, the second support mechanism 8 also includes a second position detection element 83, which is used to detect the position of the second idler group 81. The second position detection element 83 can detect the position of the second idler group 81 and can provide real-time feedback on whether the second idler group 81 is in the support position under the conveyor belt 2 in the corresponding area of ​​the second material distribution mechanism 5, ensuring that the support is in place, ensuring the stability of the second material passage gap H4, and improving the reliability of the support and the accuracy of the material distribution.

[0077] In this embodiment, both the first position detection element 73 and the second position detection element 83 are infrared sensors. The first position detection element 73, using an infrared sensor, can accurately detect the position of the first idler group 71 and provide real-time feedback on whether the first idler group 71 is in the lower support position of the conveyor belt 2 in the corresponding area of ​​the first material distribution mechanism 4, ensuring timely support and stability of the first material passage gap H2, thereby improving the material distribution accuracy and the reliability of the material distribution device. The second position detection element 83, also using an infrared sensor, can accurately detect the position of the second idler group 81 and provide real-time feedback on whether the second idler group 81 is in the lower support position of the conveyor belt 2 in the corresponding area of ​​the second material distribution mechanism 5, ensuring timely support and stability of the second material passage gap H4, thereby enhancing the material distribution accuracy and the reliability of the material distribution device.

[0078] In other embodiments, the first position detection element 73 and the second position detection element 83 can also be proximity switches. The proximity switches can detect the positions of the first idler group 71 and the second idler group 81 by sensing, and have a rapid response and strong anti-interference ability, thereby improving the working reliability of the material distribution device.

[0079] It is worth noting that the control mechanism 10 is communicatively connected to the first thickness gauge 31, the second thickness gauge 32, the third motor 722, the fourth motor 822, the first position detection element 73, and the second position detection element 83, thus constructing an intelligent control system for the material distribution device. Closed-loop data interaction and command control enable coordinated operation of thickness measurement, support, and material passage gap adjustment, significantly improving the automation level and material distribution accuracy of the device and ensuring its continuous and stable operation.

[0080] In summary, the working process of the material distribution device is roughly as follows:

[0081] (1) Material 100 is conveyed by the conveyor belt 2 and enters the detection area of ​​the first thickness gauge 31 to detect the thickness H1 of material 100 and transmit the thickness data to the control mechanism 10 in real time.

[0082] (2) After receiving the H1 data, the control mechanism 10 quickly analyzes it and sends a drive command to the third motor 722 in combination with the preset material distribution parameters. The third motor 722 drives the third piston rod in the third hydraulic cylinder 721 to move, which drives the first roller group 71 to move to the lower side of the conveyor belt 2 in the corresponding area of ​​the first material distribution mechanism 4 to complete the support preparation.

[0083] (3) After the first position detection component 73 detects that the first idler roller group 71 has moved to the corresponding preset support position, it feeds back the position confirmation signal to the control mechanism 10, and the control mechanism 10 sends an adjustment command to the first motor 412.

[0084] (4) The first motor 412 drives the first piston rod in the first hydraulic cylinder 411 to move, which drives the first stop 42 to rotate around the first pin shaft, adjusts the first material passage gap H2, and the material 100 with H1>H2 falls into the first hopper, while the material 100 that meets the requirement of H1≤H2 continues to be conveyed through the first material passage gap H2.

[0085] (5) Material 100 is conveyed by conveyor belt 2 and enters the detection area of ​​the second thickness gauge 32 to detect the thickness H3 of material 100 and transmit the thickness measurement data to the control mechanism 10 in real time.

[0086] (6) After receiving the H3 data, the control mechanism 10 quickly analyzes it and sends a drive command to the fourth motor 822 in combination with the preset material distribution parameters. The fourth motor 822 drives the fourth piston rod in the fourth hydraulic cylinder 821 to move, which drives the second idler group 81 to move to the lower side of the conveyor belt 2 in the corresponding area of ​​the second material distribution mechanism 5 to complete the support preparation.

[0087] (7) After the second position detection component 83 detects that the second roller group 81 has moved to the corresponding preset support position, it feeds back the position confirmation signal to the control mechanism 10, and the control mechanism 10 sends an adjustment command to the second motor 512.

[0088] (8) The second motor 512 drives the second piston rod in the second hydraulic cylinder 511 to move, which drives the second stop 52 to rotate around the second pin shaft, adjusts the second material passage gap H4, and the material 100 with H3>H4 falls into the second hopper. The material 100 that meets the requirement of H3≤H4 continues to be conveyed through the second material passage gap H4 to complete the material distribution operation. The material distribution device continues to run in this cycle.
