Description

Technical Field

[0001] This utility model relates to the technical field of mixing equipment, and in particular to a rotating door cooperating device. Background Technology

[0002] In the field of mixer equipment technology, the design of the discharge gate is a crucial part to ensure the smooth discharge of mixed materials and maintain stable equipment operation. Currently, while common mixer discharge gate designs on the market meet basic material discharge requirements to a certain extent, some technical problems still need to be addressed in practical applications.

[0003] Traditional mixer discharge gate designs typically involve installing polymer plates on the gate to enhance its wear resistance and service life. However, during use, the polymer plates are prone to bulging and deformation due to material friction and compression. This can cause the discharge gate to become stuck in the mixer casing during opening and closing, and in severe cases, even lead to material spoilage, seriously affecting the normal operation of the batching process. This problem not only increases production costs but also reduces production efficiency.

[0004] Furthermore, traditional discharge gate designs typically use bolts to secure the polymer panels. While this method is simple and easy to implement, gaps exist at the bolt connections. Powder from inside the mixer can easily get into these gaps when the discharge gate opens and closes, further exacerbating deformation and damage to the polymer panels. Therefore, the polymer panels need frequent replacement, increasing maintenance costs and the workload of maintenance personnel.

[0005] In response to the above problems, the industry has made some attempts and improvements, but the results have not been ideal. For example, some design solutions attempt to improve the wear resistance and deformation resistance of polymer boards by changing the material or increasing their thickness, but these methods often lead to a significant increase in production costs and cannot fundamentally solve the problems of unloading gate jamming and frequent replacement of polymer boards.

[0006] While some improvements have been made to existing mixer discharge gate technologies to address the aforementioned problems, significant shortcomings and deficiencies remain. For example, CN202516521U discloses a discharge gate design for a horizontal ribbon mixer. This design improves material flow efficiency by making the two discharge gates circular when closed, with S-shaped edges, thus facilitating the smooth discharge of agglomerated materials. However, this design does not address structural improvements to the discharge gate itself, particularly solutions for the polymer plate fixing method and the gate jamming problem.

[0007] On the other hand, TWM641285U discloses a structural improvement of the discharge gate of a mixer. By having a first discharge ramp at the first discharge end and a second discharge ramp at the second discharge end, a V-shaped discharge gap is formed when the discharge gate is closed, thereby squeezing and discharging the residual material in the gap. This design solves the problem of residual powder in the discharge gate gap to some extent, but it does not provide an effective solution for the problems of deformation, jamming, and frequent replacement of polymer plates due to material squeezing into the gap.

[0008] In summary, existing mixer discharge gate designs suffer from several problems, including easy jamming of the discharge gate, deformation of the polymer plate due to material squeezing into the gaps, and high costs and labor intensity caused by frequent replacement of the polymer plate. Therefore, there is an urgent need for a novel rotating gate and associated device design to improve the stability and durability of the mixer discharge gate, reduce the frequency of polymer plate replacement, decrease maintenance costs, and simultaneously increase production efficiency. Summary of the Invention

[0009] The technical problem to be solved by this utility model is to provide a rotating door matching device to solve the prominent problems in the field of mixer equipment technology, such as the easy jamming of the unloading door during use, the deformation of the polymer plate due to material squeezing into the gap, and the high cost and labor intensity caused by frequent replacement.

[0010] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0011] Specifically, this utility model provides a rotating door fitting device, which is mainly used for the modification of the discharge door of a mixer. The device includes a dynamic rotating door and a static door. The upper surfaces of the dynamic rotating door and the static door are respectively detachably equipped with a first wear-resistant plate and a second wear-resistant plate to enhance the wear resistance and service life of the discharge door. More importantly, a first arc-shaped convex strip and a second arc-shaped convex strip are respectively installed on the contact surfaces of the dynamic rotating door and the static door. The first arc-shaped convex strip and the second arc-shaped convex strip are fitted together to form a concave-convex sealing structure.

[0012] In practical implementation, the static door has an arc-shaped notch, within which a dynamic rotating door is rotatably installed, making the opening and closing of the unloading door smoother. The dynamic rotating door includes a door panel and a door hinge. The door panel is fan-shaped, and the door hinge is fixedly installed at the center of the fan-shaped door panel. The rotation of the door hinge drives the door panel to rotate within the arc-shaped notch of the static door. The first and second wear-resistant plates are made of high-polymer board material to improve their wear resistance and impact resistance. In addition, the first and second wear-resistant plates have densely distributed connecting holes along the joint surface of the dynamic rotating door and the static door. The dynamic rotating door and the static door have screw holes, and bolts are installed in the connecting holes and screw holes to firmly connect the dynamic rotating door, the first wear-resistant plate, the static door, and the second wear-resistant plate together.

[0013] Furthermore, the first wear-resistant plate includes a panel and a shaft plate. The panel is mounted on the upper surface of the door panel, and the shaft plate is cylindrical and divided into two parts, covering the outer surface of the door hinge to provide additional support and protection. Grooves are respectively formed on the side arc surfaces of the panel and the second wear-resistant plate, and a first arc-shaped convex strip and a second arc-shaped convex strip are fixedly installed in the grooves to ensure the integrity and stability of the sealing structure. The first and second arc-shaped convex strips are made of stainless steel to improve their corrosion resistance and service life.

[0014] The revolving door assembly provided by this utility model has the following beneficial effects:

[0015] 1. This utility model solves the prominent problems in the field of mixing equipment technology, such as the easy jamming of the unloading gate during use, the deformation of the polymer plate due to material squeezing into the gap, and the high cost and labor intensity caused by frequent replacement.

This utility model, through the concave-convex fit design of the first arc-shaped convex strip and the second arc-shaped convex strip, forms a tight sealing structure, which effectively prevents materials from squeezing into the gaps and solves the problems of deformation and jamming of polymer plates.

[0017] 3. The wear-resistant plate of this utility model is fixed to the dynamic revolving door and the static door by means of concave and convex mating, which avoids the problem of material squeezing in and polymer plate deformation caused by gaps; it enhances the stability of the sealing structure and ensures the stability and reliability of the unloading door during operation.

[0018] 4. The wear-resistant plate of this utility model is made of polymer plate material, which has excellent wear resistance and extends service life. In addition, the first wear-resistant plate has added shaft plate design, which enhances the overall structural strength, reduces the deformation and damage of polymer plate, reduces replacement frequency and maintenance costs, and brings significant economic benefits to enterprises.

[0031] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments:

[0032] Example 1

[0033] like Figures 1 to 8 As shown in the figure, this embodiment provides a rotating door matching device, which is mainly used for the modification of the unloading door of a mixer. The specific structure is as follows.

[0034] 1. Structural composition:

[0035] The device includes a dynamic revolving door 1 and a static door 2.

[0036] The upper surface of the dynamic revolving door 1 is detachably equipped with a first wear-resistant plate 3, and the upper surface of the static door 2 is detachably equipped with a second wear-resistant plate 4. Both the first wear-resistant plate 3 and the second wear-resistant plate 4 are made of high-polymer board material to enhance the wear resistance and service life of the unloading door.

[0037] A first arc-shaped convex strip 5 and a second arc-shaped convex strip 6 are respectively installed on the contact surfaces of the first wear-resistant plate 3 and the second wear-resistant plate 4. The first arc-shaped convex strip 5 is fixed to the side arc surface of the first wear-resistant plate 3, and the second arc-shaped convex strip 6 is fixed to the side arc surface of the second wear-resistant plate 4. After the two are installed together, they form a concave-convex fitting sealing structure.

[0038] 2. Specific installation method:

[0039] The static door 2 has an arc-shaped notch, within which a dynamic revolving door 1 is rotatably mounted. The dynamic revolving door 1 includes a door panel 101 and a door hinge 102. The door panel 101 is fan-shaped, and the door hinge 102 is fixedly installed at the center of the fan-shaped door panel 101. When the door hinge 102 rotates, it drives the door panel 101 to rotate within the arc-shaped notch of the static door 2, thereby opening and closing the unloading door.

[0040] The first wear-resistant plate 3 and the second wear-resistant plate 4 are provided with a dense array of connecting holes 7 along the mating surface of the dynamic revolving door 1 and the static door 2. Simultaneously, corresponding screw holes 8 are also provided on the dynamic revolving door 1 and the static door 2. The connecting holes 7 and screw holes 8 are connected by bolts, thereby securely mounting the first wear-resistant plate 3 onto the dynamic revolving door 1 and the second wear-resistant plate 4 onto the static door 2.

[0041] 3. Working principle and effects:

[0042] During the unloading process, when the dynamic rotating door 1 rotates and opens around the door shaft 102, the first arc-shaped convex strip 5 and the second arc-shaped convex strip 6 form a tight sealing structure due to their interlocking, which effectively prevents materials from being squeezed into the gaps.

[0043] This sealing structure not only solves the problem of polymer plates deforming due to material squeezing into the gaps, but also avoids the phenomenon of the unloading door getting stuck during opening and closing, significantly improving the operational stability and reliability of the mixer.

[0044] In addition, due to the excellent sealing effect, wear and deformation of the polymer board are reduced, greatly reducing the replacement frequency of the polymer board and saving maintenance costs.

[0045] Example 2

[0046] In another preferred embodiment, based on the above embodiment 1, this embodiment is further optimized, especially in the structural design of the second wear-resistant plate 4.

[0047] 1. Structural composition and optimization:

[0048] Please see Figure 1 , Figure 2 and Figure 5The first wear-resistant plate 3 includes a panel 301 and a shaft plate 302. The panel 301 is mounted on the upper surface of the door panel 101 and is used to directly contact the material and withstand the friction and impact of the material. The shaft plate 302 is cylindrical and divided into two parts, covering the outer surface of the door hinge 102. A first arc-shaped convex strip 5 is installed on the side arc surface of the panel 301, which cooperates with a second arc-shaped convex strip 6 installed on the side arc surface of the second wear-resistant plate 4 to form a sealing surface.

[0049] This design not only enhances the overall structural strength of the second wear-resistant plate 4, but also provides additional support and protection, further extending the service life of the unloading door, while ensuring the effective sealing of the dynamic rotating door 1 and the static door 2.

[0050] 2. Specific installation method and working principle:

[0051] The installation method of the first wear-resistant plate 3 is the same as that of Embodiment 1, and the panel 301 and the shaft plate 302 are fixed to the door panel 101 and the door shaft 102 respectively by bolts.

[0052] During the unloading process, when the dynamic revolving door 1 rotates open, the shaft plate 302 rotates together with the door hinge 102, while maintaining a tight sealing fit with the contact surface of the static door 2. This design effectively prevents material from being squeezed out of the gap between the door hinge 102 and the static door 2, further improving the sealing effect.

[0053] Compared with the closest existing technology (such as the structural improvement of the discharge gate of the TWM641285U mixer), this utility model has made significant innovations in the sealing structure design of the discharge gate. By adopting an arc-shaped convex strip design with concave and convex fits, this utility model forms a tighter and more reliable sealing structure, effectively solving the problem of polymer plate deformation and jamming caused by material squeezing into the gap.

[0054] In addition, the present invention has optimized the structural design of the first wear-resistant plate 3, and by adding the shaft plate 302, it provides additional support and protection, further enhancing the overall structural strength and durability of the unloading gate.

[0055] By implementing this invention, the discharge gate of the mixer exhibits higher stability and reliability during use. The smooth opening and closing of the discharge gate and the long service life of the polymer board significantly reduce equipment downtime and maintenance time, thereby improving production efficiency.

[0056] At the same time, by reducing the frequency of polymer board replacement and maintenance costs, this utility model also brings significant economic benefits to enterprises.

[0057] In a preferred embodiment, the static door 2 has an arc-shaped notch, within which a dynamic revolving door 1 is rotatably installed. This configuration allows the dynamic revolving door 1 to perfectly cooperate with the arc-shaped notch of the static door 2 during rotation, not only realizing the opening and closing function of the door but also improving the overall aesthetics and passage efficiency.

[0058] In a preferred embodiment, the dynamic revolving door 1 includes a door panel 101 and a door hinge 102. The door panel 101 is fan-shaped, and the door hinge 102 is fixedly installed at the center of the fan-shaped door panel 101. When the door hinge 102 rotates, it drives the door panel 101 to rotate within the arc-shaped notch of the static door 2. This configuration enables the smooth rotation and opening and closing of the door panel 101, effectively saving space and enhancing passage efficiency and aesthetics. The arc-shaped notch of the static door 2 perfectly matches the fan-shaped design of the door panel 101, ensuring the sealing and stability of the revolving door in the closed state.

[0059] In a preferred embodiment, the first wear-resistant plate 3 and the second wear-resistant plate 4 are made of polymer board material. The above configuration not only improves wear resistance, but also ensures the portability and corrosion resistance of the equipment, and extends the service life of the equipment. At the same time, the polymer board material is easy to process and form, which reduces production costs and improves production efficiency.

[0060] In a preferred embodiment, the first wear-resistant plate 3 and the second wear-resistant plate 4 are densely provided with connecting holes 7 along the joint surface of the dynamic revolving door 1 and the static door 2. The dynamic revolving door 1 and the static door 2 are provided with screw holes 8. Bolts are installed in the connecting holes 7 and the screw holes 8 to connect the dynamic revolving door 1 and the first wear-resistant plate 3, as well as the static door 2 and the second wear-resistant plate 4 together. The above configuration effectively improves the stability and wear resistance of the joint between the dynamic revolving door 1 and the static door 2, reduces the wear of components caused by long-term friction, ensures the smooth operation and long service life of the door, and facilitates the later maintenance and replacement of the wear-resistant plates.

[0061] In a preferred embodiment, the first wear-resistant plate 3 includes a panel 301 and a shaft plate 302. The panel 301 is mounted on the upper plane of the door panel 101, and the shaft plate 302 is cylindrical and divided into two parts, covering the outer surface of the door hinge 102. This configuration allows the first wear-resistant plate 3 to fit tightly against the door panel 101, and the cylindrical design of the shaft plate 302 effectively reduces the frictional loss of the door hinge 102 during rotation, thereby improving the durability and flexibility of the overall structure.

[0062] In a preferred embodiment, the side arc surfaces of the panel 301 and the second wear-resistant plate 4 are respectively provided with grooves, and the first arc-shaped convex strip 5 and the second arc-shaped convex strip 6 are respectively fixedly installed in the grooves; the above arrangement ensures that when the panel 301 of the first wear-resistant plate 3 and the second wear-resistant plate 4 are closed, the first arc-shaped convex strip 5 and the second arc-shaped convex strip 6 are in contact, which enhances the sealing performance and improves the stability and aesthetics of the overall structure.

[0063] In a preferred embodiment, the first arc-shaped convex strip 5 and the second arc-shaped convex strip 6 are made of stainless steel. This configuration enables the first arc-shaped convex strip 5 and the second arc-shaped convex strip 6 to have high strength and corrosion resistance, and to maintain structural stability and good performance in harsh environments for a long time.

[0064] In summary, the rotating door assembly device provided by this utility model addresses prominent problems in the field of mixer equipment technology, such as easy jamming of the discharge door, easy deformation of polymer plates, high replacement costs, and high labor intensity, through effective technological innovation and improvement. By eliminating the gap problem caused by traditional bolt connections, this utility model innovatively uses a first arc-shaped convex strip 5 and a second arc-shaped convex strip 6 respectively installed inside the first wear-resistant plate 3 and the second wear-resistant plate 4, employing a concave-convex fit design to form a tight sealing structure, effectively preventing material from squeezing into the gaps, thus solving the problems of polymer plate deformation and jamming. Simultaneously, the wear-resistant plates are made of polymer material, possessing excellent wear resistance, and the first wear-resistant plate 3 incorporates a shaft plate 301 design. This structural optimization not only enhances the overall structural strength but also provides additional support and protection for the discharge door, further extending its service life. These technological innovations and improvements enable the mixer discharge door to exhibit higher stability and reliability during use, significantly reducing equipment downtime and maintenance costs, and improving production efficiency. Furthermore, by reducing the frequency of polymer plate replacement, this invention brings significant economic benefits to enterprises. Its technological advancements and value have made important contributions to the technological progress and application development of mixing equipment, possessing broad application prospects and significant economic benefits.
