Description

Technical Field

[0001] This utility model relates to the field of material feeding technology for material feeding tubes, specifically a material feeding amount control mechanism for material feeding tubes. Background Technology

[0002] In many industrial sectors, such as building materials, chemicals, and food processing, feed pipes are extremely common components in material handling systems, playing a crucial role in transporting materials from one location to another. In actual production, precisely controlling the amount of material fed through the feed pipe is a key factor in ensuring stable production processes, meeting product quality standards, and efficient resource utilization.

[0003] However, traditional material feeding pipes have relatively simple structures, mostly only possessing basic material conveying functions and lacking effective material feeding control devices. This makes it difficult to adjust the material feeding rate in real time and accurately according to production needs during actual operation. For example, in building materials production, if the feeding rate of raw materials such as cement cannot be precisely controlled, it may lead to inaccurate concrete mix proportions, thereby affecting the strength and quality of building components; in chemical production, deviations in the amount of raw materials fed may trigger abnormal chemical reactions, affecting the purity and performance of products; in grain processing, unstable material flow can affect processing efficiency and finished product quality.

[0004] Therefore, developing a material discharge control mechanism for a discharge tube that is simple in structure, precise in control, stable and reliable, and low in cost has become an urgent technical problem to be solved in the field of industrial production. Utility Model Content

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] In the embodiments, by Figure 1-3 A material discharge amount control mechanism for a discharge pipe is provided, comprising a bracket 1, a discharge pipe 2 fixedly connected to the inner side of the bracket 1, a sleeve plate 4 fixedly connected to the bottom end of the bracket 1 by four fixing rods 3, the sleeve plate 4 fixedly connected to the outer side of the discharge pipe 2, two mounting arms 5 fixedly connected to the bottom end of the sleeve plate 4, the two mounting arms 5 being fixedly connected to each other by two first reinforcing rods 6, a transverse movement mechanism 7 for controlling the discharge amount being provided at the bottom end of the sleeve plate 4, a semi-circular sleeve 8 fixedly connected to the opposite side of the two mounting arms 5 and the transverse movement mechanism 7, the two semi-circular sleeves 8 being adapted to the outer wall of the discharge pipe 2, and a cover plate 9 fixedly connected to the bottom end of the two semi-circular sleeves 8.

[0017] With the above settings, in the initial position, the semicircular sleeve 8 connected to the transverse mechanism 7 is offset from the other semicircular sleeve 8 (the other semicircular sleeve 8 is fixed and cannot be moved), and their inner walls do not constitute an obstruction. At this time, the material can fall freely with maximum flow rate under the action of gravity. When it is necessary to reduce the amount of material falling, the transverse mechanism 7 is started or operated. The transverse mechanism 7 starts to work, pushing or pulling the semicircular sleeve 8 connected to it to move horizontally. As this semicircular sleeve 8 moves, the smaller the opening, the smaller the cross-sectional area of ​​the material discharge channel, and the smaller the allowable material flow rate; conversely, the larger the opening, the greater the flow rate. By controlling the moving distance of the transverse mechanism 7, the operator or the automation system can precisely and linearly control the size of this opening, thereby achieving stepless and continuous adjustment of the material discharge rate from fully open to fully closed (zero flow). When the transverse mechanism 7 pushes one semicircular sleeve 8 to the limit position, so that the two semicircular sleeves 8 are completely fitted together to form a complete cylinder, the bottom outlet of the discharge pipe 2 is completely closed by the two cover plates 9. At this time, the material discharge is completely cut off, and the flow rate is zero. The opening area is controlled by a transverse movement method. The opening degree and the movement distance usually have a good linear or predictable relationship, which facilitates precise quantitative control and automation.

[0018] Reference Figure 1-3The transverse mechanism 7 includes a transverse plate 71. Two transverse plates 71 are fixedly connected to the bottom end of the sleeve plate 4. An elongated oval sliding hole 72 is provided on the inner side of each of the two transverse plates 71. A sliding rod 73 is slidably connected to the inner side of each of the elongated oval sliding holes 72. A limit piece 74 is provided on the opposite side of each of the two sliding rods 73. A transverse arm 75 is fixedly connected to the opposite side of each of the two sliding rods 73. A semi-circular sleeve 8 is fixedly connected to the left end of the two transverse arms 75. The two transverse arms 75 are fixedly connected to each other by two second reinforcing rods 76. A drive mechanism 77 for driving the two transverse arms 75 to move is provided between the two upper second reinforcing rods 76 and the two upper first reinforcing rods 6. With the above structural setup, the operator is positioned beside the equipment, ready to adjust the material discharge rate. The drive mechanism 77 actuates, causing the transverse arm 75 to move. Throughout the movement, the slide bar 73 slides within the elongated oval sliding hole 72 of the horizontal plate 71. The elongated oval sliding hole 72 acts as a precise guide groove, ensuring that the entire transverse arm 75 assembly moves only along the designed horizontal direction without swaying, deflection, or jamming. The limiting piece 74 prevents the slide bar 73 from accidentally dislodging from the elongated oval sliding hole 72, increasing operational safety and reliability. The horizontal movement of the transverse arm 75 directly moves the semi-circular sleeve 8 fixed to its left end. As previously mentioned, this semi-circular sleeve 8 undergoes relative displacement with another fixed semi-circular sleeve 8, thereby precisely changing the opening of the discharge pipe 2 outlet and achieving flow control.

[0019] Reference Figure 1-3 The drive mechanism 77 includes a mounting plate 771. The outer sides of the two upper second reinforcing rods 76 are fixedly connected to the mounting plate 771. The left ends of the two mounting plates 771 are fixedly connected to the cylinders 772. The inner sides of the two cylinders 772 are slidably connected to the cylinder push rods 773. The left ends of the two cylinder push rods 773 are respectively fixedly connected to the right ends of the two upper first reinforcing rods 6. With the above structural setup, the two cylinders 772 are not connected, the compressed air transverse mechanism 7 is in an initial position, and the discharge pipe 2 is fully open. Starting the cylinders 772 connects the compressed air pipeline to the rod chambers of the two cylinders 772. The left end of the cylinder push rod 773 is fixed to the stationary first reinforcing rod 6. This means that the cylinder push rod 773 itself cannot move. When compressed air enters the rod chamber of the cylinder 772, the gas pressure pushes the piston of the cylinder 772. Since the piston rod (cylinder push rod 773) is fixed, according to the principle of action and reaction, this thrust will react on the cylinder 772 body itself. The cylinder body 772 receives a leftward thrust, which is transmitted to the second reinforcing rod 76 through the mounting plate 771, thereby driving the entire transverse arm 75 assembly (including the slide rod 73, the second reinforcing rod 76, and the semi-circular sleeve 8) to slide to the left along the elongated sliding hole 72. The horizontal sliding arm 75 moves to the left, directly causing the semi-circular sleeve 8 fixed at its left end to move to the left as well, thereby reducing the outlet opening of the discharge pipe 2 and consequently reducing the discharge volume. The distance of movement (i.e., the size of the opening) is controlled by adjusting the air intake of cylinder 772 or by using a cylinder 772 with adjustable stroke. The system can roughly control the air intake by controlling the energizing time (pulse) of the solenoid valve, or use a cylinder 772 with a position sensor to achieve more precise closed-loop control (note that this control process is common knowledge to those skilled in the art and will not be elaborated further). When it is necessary to increase the discharge volume, compressed air is guided to the rodless chamber of cylinder 772 (the air chamber on the other side of the piston). Similarly, because the cylinder push rod 773 is fixed, the air pressure will push the cylinder body 772 to the right, thereby causing the horizontal sliding arm 75 and the semi-circular sleeve 8 to move to the right, increasing the outlet opening. Once the required opening is reached, the air pressure will keep the piston position stationary, thereby locking the current discharge opening.

[0020] Reference Figure 1-3 The bracket 1 has two reinforcing seats 10 fixedly connected to both the front and rear ends, and each of the four reinforcing seats 10 has a mounting hole 11. With the above structural design, the impact of the material and changes in airflow during the material feeding process may cause vibrations in the entire mechanism and the feeding pipe 2. The rigid connection between the reinforcing seat 10 and the mounting surface constitutes a robust base, greatly increasing the natural frequency of the entire system and effectively suppressing vibrations and preventing their amplification. This ensures the stability and accuracy of the operation of precision adjustment components such as the transverse mechanism 7. The mounting holes 11 provide standard and reliable connection points, allowing the entire mechanism to be securely installed on a pre-prepared foundation (such as a steel frame, concrete platform, or equipment body) using high-strength bolts, anchor bolts, or other fasteners.

[0021] Reference Figure 1-3 Among them, a ladder 12 is provided on the right side of the support 1; With the above structural setup, when it is necessary to adjust the flow rate, conduct routine inspections, or handle minor malfunctions, personnel can quickly and directly reach the work site without spending time searching for and moving the ladder, which greatly saves time and manpower.
