Description

Technical Field

[0001] The utility model relates to the field of mixers, in particular to an anti-piling and material discharging mechanism of a mixer. Background Art

[0002] As a key production equipment, the performance of the mixer's discharge mechanism directly affects the product quality and production efficiency. Traditional mixer discharge mechanisms generally use butterfly valves as components to control the discharge. Butterfly valves have been widely used in the industry due to their simple structure, easy operation, and low cost.

[0003] However, during the closing process, the butterfly valve cannot effectively intercept the material that is about to pass through the valve due to the limitations of its working principle. When the material flows through the butterfly valve, if the valve plate has not been completely closed, the material is easily squeezed between the valve plate and the valve seat, forming a blockage. This blockage phenomenon not only affects the smoothness of material discharge, but also, after long-term operation, due to the repeated squeezing and friction of the material in the butterfly valve, the valve plate and the valve seat are seriously worn. This wear not only reduces the sealing performance of the butterfly valve, but may also cause material leakage. When the mixer stops working or the discharge amount needs to be adjusted, the undischarged material is likely to accumulate at the butterfly valve, causing inconvenience to subsequent operations. Utility Model Content

[0032] Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative work shall fall within the scope of protection of the present invention.

[0033] Reference Figures 1-6 When the valve plate 3 is closed, the cross-section of the material guide member 5 is trapezoidal, which is used to block the material from being discharged when the valve plate 3 is closed, so as to avoid the material from being blocked between the valve plate 3 and the material discharge pipe 2. When the valve plate 3 is opened, the cross-section of the material guide member 5 is in an inverted trapezoidal shape, which is used to guide the material to be discharged in the material discharge pipe 2; a control member 4 is installed on the material discharge pipe 2, and the control member 4 is set to move on the outside of the material discharge pipe 2, so as to control the rotation of the valve plate 3 and the deformation of the material guide member 5; the coordinated action of the valve plate 3 and the material guide member 5 effectively solves the problem of material being discharged in the material discharge pipe 2. The accumulation and blockage problems during the material discharge process, when the valve plate 3 is closing, the material guide 5 can be deformed and have a trapezoidal cross-section, which can effectively block the material from continuing to fall and prevent the material from accumulating between the valve plate 3 and the discharge pipe 2, avoiding poor material discharge or equipment failure caused by material accumulation. When the valve plate 3 is opened, the material guide 5 is deformed into an inverted trapezoid. Its shape change not only reduces the material flow resistance, but also guides the material to fall smoothly, thereby improving the material discharge efficiency. The entire anti-stacking discharge mechanism is integrated inside the discharge pipe 2, and the coordinated work of the internal components can be achieved by moving the control part 4 on the outside. The compact structural design not only saves space, but also makes the entire mechanism more stable and easy to maintain. The high integration also improves the overall performance and reliability of the equipment.

[0034] Reference Figure 3 and Figure 4The control member 4 includes: a connecting hole 402, which is opened on the control member 4; a rack 302, which is installed on the side wall of the connecting hole 402; a gear 301, which is arranged in the connecting hole 402 and connected to the rack 302, and the valve plate 3 is connected to the gear 301; a movable seat 403, the inner wall of the discharge pipe 2 is provided with a through hole 201, and the movable seat 403 is connected in the through hole 201; a control rod 404, one end of which is connected to the movable seat 403, and the other end is connected to the guide member 5. The design of the control member 4 enables the rotation of the valve plate 3 and the deformation of the guide member 5 to be precisely controlled by the external power source 102. The transmission mechanism of the rack 302 and the gear 301 ensures the stability and reliability of the rotation of the valve plate 3, and the connection between the control rod 404 and the movable seat 403 realizes direct control of the deformation of the guide member 5. This design simplifies the operation process, reduces the difficulty of operation, and improves the degree of automation of the equipment.

[0035] Reference Figure 1 、 Figure 2 and Figure 3 , mixing container 1, the discharge pipe 2 is connected to the mixing container 1, and the control component 4 is arranged below the mixing container 1; the mixing container 1 includes: a mounting base 101, mounted on the mixing container 1; a power source 102, mounted on the mounting base 101, a power shaft of the power source 102 is connected to the control component 4, and the power source 102 installed on the mixing container 1 provides the control component 4 with moving power, thereby realizing remote and precise control of the valve plate 3 and the material guide component 5, which not only improves work efficiency, but also reduces the difficulty and cost of manual operation. The stable output of the power source 102 also ensures the smooth operation and long-term reliability of the entire mechanism. The power source 102 adopts a cylinder, and can also adopt a linear motor.

[0036] Reference Figure 1 and Figure 2 The control member 4 further includes: an ear plate 401 , which is mounted on the control member 4 , a power shaft of the power source 102 is connected to the ear plate 401 , and the power source 102 is used to provide moving power for the ear plate 401 .

[0037] Reference Figure 3 and Figure 5 The projection shape of the valve plate 3 is circular; the projection shape of the control part 4 is annular; the material of the material guide part 5 is rubber, and silicone can also be used. The material guide part 5 is made of soft materials such as rubber or silicone. These materials have good elasticity and wear resistance, and can maintain stable performance during long-term use. The soft material can also better adapt to the shape changes of the valve plate 3 when it is opened and closed, ensuring the consistency of the material guiding effect. This material selection also improves the corrosion resistance and weather resistance of the equipment, and extends the service life of the equipment.

[0038] During use, the materials in the mixing container 1 are in a mixed state, the discharge pipe 2 is connected to the bottom of the mixing container 1, the valve plate 3 is in a closed state, and the cross-section of the material guide member 5 is trapezoidal, which effectively prevents the material from falling into the discharge pipe 2. The control member 4 is installed under the mixing container 1. When it is necessary to start discharging, the power source 102 receives a start signal, and the power shaft of the power source 102 pushes the control member 4 to move outside the discharge pipe 2 through the ear plate 401. The movement of the control member 4 drives the valve plate 3 to start rotating through the transmission mechanism of the rack 302 and the gear 301, and gradually opens from a closed state. As the valve plate 3 opens, the gear 301 installed on the valve plate 3 continuously engages with the rack 302 to ensure that the valve plate 3 rotates smoothly and reliably. At the same time, the moving seat 403 in the control member 4 is connected to the material guide member 5 through the control rod 404. As the control member 4 At the same time, the control rod 404 pulls the material guide piece 5 in the opposite direction to restore its cross-sectional shape from an inverted trapezoid to a trapezoid, blocking the material from falling again and preventing the material from accumulating between the valve plate 3 and the discharge pipe 2, thereby avoiding poor discharge or equipment failure caused by material accumulation.

[0039] In summary, compared with the existing technology, it has the following beneficial effects:

[0040] By setting the material guide member 5 in the discharge pipe 2, when the valve plate 3 is closed, the material guide member 5 can effectively prevent the material from continuing to fall, avoiding the material from being squeezed between the valve plate 3 and the valve seat to form a blockage, avoiding repeated squeezing and friction of the material between the valve plate 3 and the valve seat, and significantly reducing the wear of the valve plate 3 and the valve seat, which not only extends the service life of the valve, but also maintains the good sealing performance of the valve, and prevents the occurrence of material leakage.

[0041] By optimizing the design of the feeding mechanism, the overall performance of the mixer is improved, the smoothness and reliability of the feeding process are improved, which helps to reduce the occurrence of equipment failures and improves production efficiency. When the mixer stops working or the feeding amount needs to be adjusted, the anti-stacking feeding mechanism can ensure that undischarged materials will not accumulate at the valve. The design of the material guide 5 effectively blocks the material when the valve plate 3 is closed, avoiding the occurrence of accumulation and providing convenience for subsequent operations.
