Description

Technical Field

[0001] This application relates to a protective cover and a mixer. Background Technology

[0002] In the manufacturing process of inks and other materials, there is a step of mixing and stirring various materials (such as resins, powders, organic solvents, etc.) required to produce qualified inks. During stirring, dust and solvent splashes are easily generated, which can affect the working environment and even injure operators. Therefore, it is desirable to avoid the adverse effects caused by dust and other contaminants generated during the stirring process.

[0003] Furthermore, before mixing, various materials need to be manually added to the mixing container. However, the material containers are usually quite heavy, making the feeding operation—lifting multiple containers of various materials separately and pouring the materials into the mixing container—difficult and labor-intensive. Therefore, it is desirable to reduce the labor required for the feeding operation.

[0004] CN219559486U (Patent Document 1) relates to a pulping machine with a protective cover, which covers the upper part of the mixing tank to prevent material inside the mixing tank from splashing onto people. However, Patent Document 1 does not mention how to reduce labor during the feeding operation of putting materials into the mixing tank.

[0005] Therefore, reducing the labor required for feeding operations while avoiding the adverse effects of dust generated during the mixing process has become a key issue. Utility Model Content

[0006] Problems to be solved by utility models

[0007] This application was made in view of the above-mentioned situation, and its purpose is to provide a protective cover and mixer that can avoid or reduce the adverse effects caused by dust and other pollutants generated during the mixing process, while reducing the labor required by operators when performing feeding operations.

[0008] Solution for solving the problem

[0009] To achieve the above objectives, this application provides a protective cover for a mixer. The cover includes a cover body capable of being placed on the opening edge of a mixing container for containing materials to cover the opening of the mixing container and form a mixing space. A through hole for the mixing shaft of the mixer to pass through is formed on the top surface of the cover body. A feed port that can be opened and closed is provided on the side of the cover body, through which materials to be mixed are fed into the mixing container. A support plate for supporting a material container containing the materials is integrally formed on the side of the cover body. The support plate extends outward from the lower edge of the feed port away from the side of the cover body.

[0010] According to this structure, since the main body of the protective cover can cover the opening of the mixing container and form a mixing space, it can avoid or reduce the adverse effects of dust generated during the mixing process on the working environment and solvent splashing onto the operators. In addition, since the main body of the protective cover is provided with a feeding port and a support plate extends from or below the lower edge of the feeding port, the operator can use the support plate to support the lifted material bucket during the feeding operation, thereby reducing the labor required for feeding.

[0011] In other words, the protective cover of this application, because it is equipped with a feeding port and a support plate, not only has a protective function (protecting the working environment and operators), but also has the function of facilitating feeding operations and reducing the labor required for feeding.

[0012] In at least one embodiment, the support plate extends horizontally outward from the entire extent of the lower edge of the feed port toward the outside of the protective cover body.

[0013] According to this structure, the support plate can provide support for the material bucket lifted by the operator throughout the entire feeding port area. In addition, because the support plate extends horizontally, the support for the material bucket is more stable.

[0014] In at least one embodiment, a dust suction port is formed at a position on the side of the protective cover body that is different from the position where the feeding port is formed, and a dust suction device sucks up the dust inside the protective cover body through the dust suction port.

[0015] This structure allows for the timely removal of dust generated during the mixing process, thus preventing adverse effects caused by dust even when the feed inlet is open.

[0016] In at least one embodiment, an observation port that can be opened and closed is formed at a position on the side of the protective cover body that is different from the position where the feeding port is formed.

[0017] According to this structure, the operator can observe the stirring state inside the main body of the protective cover through the observation port, which makes it easier for the operator to grasp the stirring process and make appropriate adjustments when necessary.

[0018] In at least one embodiment, a baffle is erected on the edge of the top surface of the protective cover body, at least in the area corresponding to the feeding port.

[0019] According to this structure, the baffle can prevent dust and foreign objects accumulated on the top surface of the protective cover from entering the mixing container through the feeding port, and prevent dust generated during feeding from reaching the top surface of the protective cover or adhering to the mixing shaft.

[0020] In at least one embodiment, the shield body is truncated conical in shape, and a baffle is erected along the entire edge of the top surface of the shield body.

[0021] This structure further prevents dust generated during feeding from reaching the top surface of the protective cover or adhering to the mixing shaft. Furthermore, the truncated conical shape of the protective cover facilitates molding, reduces dead zones for foreign matter accumulation, saves space, and makes feeding and other operations easier for operators.

[0022] In at least one embodiment, the protective cover further includes a suspension member, which is a flexible constraint type member. One end of the suspension member is detachably connected to the top surface of the protective cover body, and the other end of the suspension member is used to connect to the mixer.

[0023] According to this structure, since the cover can be connected to the mixer by means of a suspension component, the cover can move with the mixer, making it easy to move the cover to a designated position above the mixing container, and also reducing the labor required for manually disassembling and moving the cover.

[0024] In at least one embodiment, the length of the suspension member is set such that when the suspension member suspends the protective cover body, the length of the suspension member projected in the vertical direction is greater than the distance between the other end of the suspension member and the connection portion of the mixer to the top surface of the protective cover body when the protective cover body is placed on the opening edge of the mixing container.

[0025] According to this structure, when the main body of the protective cover is placed on the opening edge of the mixing container, the suspension member does not impose any constraint on the main body of the protective cover. Therefore, the vibration of the mixer is difficult to be transmitted to the protective cover through the suspension member, and the vibration of the protective cover caused by the high-frequency vibration of the mixer can be prevented.

[0026] In at least one embodiment, the suspension component is a chain, and there are at least two chains.

[0027] According to this structure, the low cost and high durability of the chains allow for the prevention of guard vibration caused by the high-frequency vibration of the mixer while balancing cost and durability. Furthermore, using at least two chains ensures that the guard is connected to the mixer in a balanced manner.

[0028] On the other hand, this application also provides a mixer that includes the aforementioned protective cover.

[0030] According to this application, a protective cover and mixer can be provided that can avoid the adverse effects caused by dust generated during the mixing process, while reducing the labor required by operators when feeding materials. Attached Figure Description

[0039] Next, specific embodiments of this application will be described with reference to the accompanying drawings. It should be noted that the dimensions of the components in the drawings are merely schematic and do not represent a limitation on the actual product dimensions. Furthermore, for ease of illustration, the dimensions of the same components in different drawings may differ; such differences should not be construed as a conflict of technical solutions.

[0040] like Figures 1-6 As shown, the protective cover 1 includes a suspension member 5, which is connected to the bottom of the crossbeam 7 of the mixer. The mixing shaft 8 of the mixer extends into the protective cover 1 from the bottom of the crossbeam 7 through a through hole 14 on the top surface of the protective cover 1. An impeller 9 (disc impeller) is installed at the lower end of the mixing shaft 8. With the protective cover 1 covering the opening of the mixing container (not shown), the impeller 9 is located inside the mixing container and can mix the material inside the mixing container.

[0041] The protective cover 1 includes a main body 10, and the side of the main body 10 is provided with a feeding port 11, a dust suction port 12, and an observation port 13. A support plate 2 and a baffle 3 are integrally formed on the protective cover 1 with the main body 10. A detailed description follows.

[0042] (1. Protective shield)

[0043] like Figure 1 As shown, the protective cover 1 is a cover for a mixer, including a metal cover body 10, which is truncated conical in shape. The size of the lower opening of the cover body 10 matches the opening size of the mixing container. A flange 101 is provided at the lower edge of the cover body 10. By overlapping or engaging with the opening edge of the mixing container, the cover body 10 is placed on the opening edge of the mixing container to cover the opening of the mixing container and form a mixing space. The mixing container is used to contain various materials such as resins and powders.

[0044] like Figures 1-6 As shown, a feeding port 11, a dust suction port 12, and an observation port 13 are respectively provided at different positions on the circumferential direction of the side of the protective cover body 10. A through hole 14 for the stirring shaft 8 of the mixer to pass through is formed on the top surface of the protective cover body 10 (for example, approximately at the center). A baffle 3 is erected on the top surface of the protective cover body 10 (specifically, at the edge of the top surface).

[0045] (1-1. Feed port and support plate)

[0046] like Figure 1 and Figure 2As shown, the feeding port 11 is designed to be openable and closable. During the feeding operation, the operator opens the feeding port 11 and feeds the material to be mixed into the mixing container through the feeding port 11. After the feeding operation is completed, the operator closes the feeding port 11 to form a mixing space, which is preferably a well-sealed space that prevents dust leakage. The size of the feeding port 11 can be set to be greater than or equal to the opening size required for feeding the material. The opening and closing structure of the feeding port 11 is not limited, as long as it ensures that the operator can open and close the feeding port 11.

[0047] A support plate 2 for supporting a material container is integrally formed on the side of the protective cover body 10. The support plate 2 extends outward from the side of the protective cover body 10 away from the lower edge of the feeding port 11. Specifically, it may extend outward from the side of the protective cover body 10 away from the lower edge of the feeding port 11, or it may extend outward from the side of the protective cover body 10 away from the lower edge of the feeding port 11. The specific shape and extension area of ​​the support plate 2 are not limited, as long as it can provide support for the material container.

[0048] When providing support for the material container, the support plate can extend horizontally or at a predetermined angle relative to the horizontal plane, either upwards or downwards. Preferably, the support plate 2 extends horizontally from the entire lower edge of the feeding port 11 toward the outside of the protective cover body 10. When the operator lifts the material container for feeding, the container receives support from the support plate 2 by contacting it, thereby reducing labor intensity.

[0049] The support plate 2 can be made of the same metal material as the shield body 10 and integrally formed with the shield body 10, or the support plate 2 and the shield body 10 can be formed separately and connected to each other by welding or other means, both of which are included in "the support plate is integrally formed on the side of the shield body". In addition, as long as the required protection and support can be ensured, the materials of the shield body 10 and the support plate 2 can also be other than metal materials.

[0050] (1-2. Baffle)

[0051] like Figure 1 and Figure 6 As shown, the baffle 3 is located on the edge of the top surface of the protective cover body 10, in the area corresponding to the feeding port 11. The "corresponding area" refers to the area when the feeding port 11 is viewed from the front (refer to...). Figure 1 and Figure 2The area on the top surface of the protective cover body 10 that overlaps with the feeding port 11 in the vertical direction. The baffle 3 can be erected on a part of the top surface of the protective cover body 10, or it can be erected along the entire edge of the top surface of the protective cover body 10.

[0052] In other words, a baffle 3 is erected on the edge of the top surface of the protective cover body 10, at least in the area corresponding to the feeding port 11.

[0053] The material, height, and location of the baffle 3 are not limited, as long as it can prevent dust from adhering to the part of the stirring shaft 8 above the top surface of the cover body 10 and prevent foreign objects on the top surface of the cover body 10 from entering the feed inlet 11. For example, the baffle 3 can also be located on the top surface of the cover body 10 slightly inside the edge. In addition, the baffle 3 can be made of the same metal material as the cover body 10 and integrally formed with the cover body 10, or the baffle 3 and the cover body 10 can be formed separately and connected to each other by welding or other methods.

[0054] (1-3. Suction port and observation port)

[0055] like Figure 1 and Figure 3 As shown, a dust suction port 12 is formed at a position on the side of the protective cover body 10, which is different from the position of the feeding port 11. The dust suction device draws dust from inside the protective cover body 10 through the dust suction port 12.

[0056] The specific location of the suction port 12 can be adjusted appropriately according to the layout requirements of the vacuuming device and suction pipe, and is not limited to the location shown in the attached figure. In addition, the size and shape of the suction port 12 are not limited.

[0057] like Figure 5 As shown, an observation port 13, which can be opened and closed, is formed on the circumferential side of the protective cover body 10 at a position different from that of the feeding port 11. Preferably, the observation port 13 is located close to the operator's workbench to facilitate observation. The size of the observation port 13 and its opening and closing structure are not limited.

[0058] It should be noted that either the dust suction port 12 or the observation port 13 can be provided on the main body 10 of the protective cover, or both the dust suction port 12 and the observation port 13 can be provided on the main body 10 of the protective cover.

[0059] (2. Suspension components)

[0060] like Figures 2-6 As shown, the suspension component 5 is a flexible constraint type component, one end of which is detachably connected to the top surface of the protective cover body 10, and the other end is used to connect to the mixer (e.g., the bottom of the crossbeam 7).

[0061] For example, one end of the suspension member 5 is threaded to a bolt provided on the top surface of the protective cover body 10, and the other end is threaded to a bolt provided on the bottom of the crossbeam 7. The suspension member 5, as a flexible restraint type member, can be made of chains, ropes, etc., and in a relaxed state without being subjected to tension, it has the function of preventing or mitigating the transmission of the vibration of the mixer to the protective cover 1 through the suspension member 5.

[0062] Preferably, the length of the suspension member 5 is set such that, when the cover body 10 is placed on the opening edge of the mixing container, the suspension member 5 does not impose any constraint on the cover body 10. Furthermore, the length of the suspension member 5 projected in the vertical direction when suspending the cover body 10 is greater than the distance between the other end of the suspension member 5 and the connection point of the mixer to the top surface of the cover body 10 when the cover body 10 is placed on the opening edge of the mixing container.

[0063] The suspension component 5 is preferably made of chain (e.g., metal), and the number of chains is at least two. When the suspension component 5 is made of chain, the length of the suspension component 5 refers to the maximum length of the chain when it is fully extended.

[0064] exist Figure 6 In the structure, two chains, serving as suspension components 5, are symmetrically arranged across the stirring shaft 8. However, the number and position of the chains are not limited and can be adjusted according to actual needs.

[0065] (3. Other instructions)

[0066] This application also provides a mixer that includes the aforementioned protective cover of this application.

[0067] As a material, it can be ink, various materials required for ink manufacturing, or other materials that require a stirring process. In the production of high-viscosity ink, the stirring impeller 9 will generate high-frequency vibrations during stirring. At this time, the effect of using the suspension component 5 (more specifically, a metal chain) to install the protective cover 1 on the mixer is more significant.

[0068] In this application, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; "linking" can be a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of these terms in this application based on the specific circumstances.

[0069] In the description of this specification, the specific features, structures, materials or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0070] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
