Description

Technical Field

[0001] The present application relates to the technical field of mixing equipment, and in particular to a powder tank docking mechanism. Background Art

[0002] The air jet mill can change the air in the air source into inert gases such as nitrogen and carbon dioxide, making the machine body an inert gas protection device, which is more suitable for crushing and processing materials that are easy to oxidize. In the production process of magnetic materials, there are high requirements for the fineness and purity of the finished magnetic powder. In addition, the magnetic powder has the characteristic of being easy to oxidize, so the air jet mill is usually used to crush the magnetic material.

[0003] The air flow mill is usually mounted on a support, and this arrangement makes the feed port of the air flow mill at a certain height from the ground. In the existing process of using the air flow mill to grade and crush magnetic materials, it is usually necessary to use a crane to lift the powder storage tank placed on the ground, connect and fix the discharge port of the tank with the feed port of the air flow mill, so as to complete the subsequent magnetic material crushing operation.

[0004] However, when using a crane to lift the powder storage tank, the tank body has a certain weight and the crane's sling will cause the tank body to shake, making it difficult to dock the powder storage tank's discharge port with the jet mill's feed port. If the docking time is too long, it may even cause the tank body to fall off the crane's sling, causing safety problems. Utility Model Content

[0005] In order to improve the shaking of the powder tank on the crane sling and improve the stability of the connection between the powder tank and the air flow mill, the present application provides a powder tank connection mechanism.

[0006] The powder tank docking mechanism provided in this application adopts the following technical solution:

[0007] A powder tank docking mechanism comprises a support frame fixedly connected to a support, the support frame is located between a traveling crane and the support for supporting the powder tank, a limiting opening for the powder tank to be inserted is provided on a side of the support frame away from the support, and the limiting opening is aligned with a feed port of a jet mill.

[0008] By adopting the above technical solution, the support frame is arranged above the support and between the crane and the support, and a limiting opening is provided on the support frame for the powder tank to be inserted into. When the crane hoists the tank body and pulls the tank body up, the tank body enters the limiting opening and abuts against the support frame. The limiting opening and the feed port of the air flow mill are aligned with each other, so that the powder tank can be supported by the support frame during the docking process with the air flow mill. When the tank body passes through the limiting opening, the support frame is equivalent to playing a certain guiding role on the tank body, reducing the amplitude of the tank body shaking, improving the shaking of the powder tank on the crane sling, and improving the stability of the powder tank and the air flow mill docking.

[0009] Furthermore, the support frame includes a frame body and a support plate, the frame body is fixedly connected to the support, the support plate is arranged on a side of the frame body away from the support, the limit opening is opened on the support plate, and a baffle is fixedly connected to a side of the support plate close to the frame body, and the baffle is circumferentially arranged at the edge of the limit opening and is perpendicular to the support plate.

[0010] By adopting the above technical solution, the frame is fixedly connected to the support of the airflow mill, providing a mounting platform for the support plate, and the limit opening is opened on the support plate, which has a limiting effect on the powder tank during the lifting process. The baffle is fixedly connected to the bottom of the support plate and is arranged around the edge of the limit opening. The setting of the baffle can increase the contact area between the support plate and the powder tank, improve the limiting effect of the support plate on the powder tank, and improve the stability of the connection between the powder tank and the airflow mill.

[0011] Furthermore, a guide plate is fixedly connected to a side of the baffle away from the side connected to the support plate, and the guide plate is inclined toward the outside of the limit opening from the side connected to the baffle to the side close to the support.

[0012] By adopting the above technical scheme, the guide plate is fixedly connected to the bottom of the baffle and is inclined in a trumpet shape toward the outside of the limit opening. The tank body passes through the guide plate and the baffle in sequence during the lifting process. When the tank body passes through the guide plate, the narrowing effect of the guide plate can gradually reduce the shaking amplitude of the tank body. The coordinated setting between the guide plate and the baffle can improve the limiting effect of the support plate on the powder tank, improve the shaking of the powder tank on the traveling sling, and improve the stability of the connection between the powder tank and the air flow mill.

[0013] Furthermore, a limiting rod for enclosing the limiting opening is rotatably connected to the supporting plate.

[0014] By adopting the above technical scheme, the limit rod is rotatably connected to the support plate, and the setting of the limit rod can enclose the limit opening. When the powder tank is inserted into the limit opening and abuts against the support plate, the limit rod is rotated to abut against the outer wall of the tank body, so as to realize the clamping and fixing of the tank body, improve the limiting effect of the support plate on the powder tank, improve the shaking of the powder tank on the traveling sling, and improve the stability of the connection between the powder tank and the air flow mill.

[0015] Furthermore, a groove for the powder supply tank to be inserted into is provided at the middle position of the limiting rod.

[0016] By adopting the above technical solution, the groove is arranged at the middle position of the limit rod. When the limit rod is rotated to abut against the powder tank, the setting of the groove can improve the fit between the limit rod and the powder tank, increase the contact area between the limit rod and the powder tank, improve the limiting effect of the support plate on the powder tank, improve the shaking of the powder tank on the traveling sling, and improve the stability of the connection between the powder tank and the air flow mill.

[0017] Furthermore, a limiting block is provided on a side of the support plate away from the side rotatably connected to the limiting rod, and a limiting groove for the limiting rod to be inserted is provided on a side of the limiting block away from the support plate.

[0018] By adopting the above technical solution, the limit block is arranged on the side of the support plate away from the rotation connection with the limit rod. When the limit rod is rotated to abut against the powder tank, the end position of the limit rod is inserted into the limit groove of the limit block, thereby achieving the effect of clamping and fixing with the support plate, improving the stability of the limit rod in fixing and limiting the powder tank, improving the shaking of the powder tank on the traveling sling, and improving the stability of the connection between the powder tank and the air flow mill.

[0019] Furthermore, the limit block and the corresponding position on the limit block are provided with magnetic blocks for mutual adsorption.

[0020] By adopting the above technical scheme, the setting of the magnetic block can achieve the effect of magnetic fixation between the limit rod and the limit block, improve the clamping stability between the limit rod and the limit block, thereby improving the stability of the limit rod fixing and limiting the powder tank, improving the shaking of the powder tank on the traveling sling, and improving the stability of the connection between the powder tank and the air flow mill.

[0021] Furthermore, a traction rope for pulling the limit rod to rotate is provided on one end of the limit rod away from the support plate for rotation.

[0022] By adopting the above technical solution, the setting of the traction rope can facilitate the operator to rotate the limit rod. The operator can pull the traction rope to rotate the limit rod by standing on the ground, so that the limit rod is stuck in the limit block and abuts against the outer wall of the powder tank, thereby improving the shaking of the powder tank on the traveling sling and improving the stability of the connection between the powder tank and the air flow mill.

[0023] Furthermore, a pushing member for lifting the support plate is provided on a side of the frame away from the support.

[0024] By adopting the above technical solution, the setting of the pushing member can enable the frame to lower and lift the support plate, so that the support frame can match powder tanks of different heights. By adjusting the relative height between the support plate and the air flow mill, the support stability of different powder tanks is improved, thereby improving the shaking of the powder tank on the traveling sling and improving the stability of the connection between the powder tank and the air flow mill.

[0025] Furthermore, the pushing member includes a cylinder body and a pushing rod installed in the cylinder body, the cylinder body is fixedly connected to the frame body, and the support plate is detachably connected to an end of the pushing rod away from the cylinder body.

[0026] By adopting the above technical scheme, the cylinder body and the frame body are fixedly connected, the push rod is driven by the cylinder body to push the support plate, and the support plate and the push rod are detachably connected, so that the support plate can be replaced. Different sizes of limit openings can be opened on different support plates to accommodate powder tanks of different specifications, thereby improving the shaking of the powder tank on the traveling sling and improving the stability of the connection between the powder tank and the air flow mill.

[0027] In summary, the present application includes at least one of the following beneficial technical effects:

[0028] 1. The support frame is set above the support and between the crane and the support. The support frame is provided with a limit opening for the powder tank to be inserted. When the crane lifts the tank body up, the tank body enters the limit opening and abuts against the support frame. The limit opening is aligned with the feed port of the jet mill, so that the powder tank can be supported by the support frame during the docking process with the jet mill. When the tank body passes through the limit opening, the support frame is equivalent to playing a certain guiding role for the tank body, reducing the shaking amplitude of the tank body;

[0029] 2. The baffle is fixedly connected to the bottom of the support plate and is arranged around the edge of the limit opening, which increases the contact area between the support plate and the powder tank and improves the limiting effect of the support plate on the powder tank. The guide plate is fixedly connected to the bottom of the baffle and is arranged in a trumpet shape to the outside of the limit opening. When the tank body passes through the guide plate from bottom to top, the narrowing effect of the guide plate gradually reduces the shaking amplitude of the tank body, improves the shaking of the powder tank on the traveling sling, and improves the stability of the connection between the powder tank and the air flow mill;

[0030] 3. The support plate is rotatably connected to a limiting rod. When the powder tank is inserted into the limiting opening and abuts against the support plate, the limiting rod encloses the limiting opening.

[0036] In order to make the purpose, technical solutions and advantages of this application more clear, the following Figure 1-4 And embodiments, the present application is further described in detail.

[0037] The embodiment of the present application discloses a docking mechanism for a powder tank 2. The words such as "upper" and "lower" used to express the positional relationship in the embodiment are determined with reference to the placement and installation position of the docking mechanism for the powder tank 2 when it is in a normal use state.

[0038] Reference Figure 1 The support 4 is placed on the ground and the air mill 3 is installed. The powder tank 2 is placed on the ground and lifted by the crane 5. Figure 2 The powder tank 2 docking mechanism includes a frame 11 and a support plate 12. The frame 11 is fixedly connected to the support 4. The support plate 12 is installed on the frame 11 to support and limit the powder tank 2 during the docking process with the air flow mill 3.

[0039] Reference Figure 1 and Figure 2 The frame 11 in this embodiment includes support rods 111 and cross beams 112 for enhancing the stability of the frame 11. The number of support rods 111 is preferably four, and the four support rods 111 are vertically fixedly connected to the top of the support 4. The number of cross beams 112 is correspondingly four, and each cross beam 112 is vertically fixedly connected to two adjacent support rods 111.

[0040] The end of the support rod 111 away from the support 4 is provided with a push member 18 for lifting the support plate 12, and the push member 18 includes a cylinder 181 and a push rod 182. The cylinder 181 in this embodiment is embedded in the support rod 111, and the cylinder 181 is located at the center axis of the support rod 111 and is fixedly connected to the support rod 111. The push rod 182 is installed in the cylinder 181 and driven by the cylinder 181.

[0041] The heights of powder cans 2 of different specifications are different. By driving the support plate 12 through the push rod 182 , the support plate 12 can quickly adjust the relative position with the powder can 2 so that the height of the support plate 12 matches that of the powder can 2 .

[0042] The support plate 12 is detachably connected to the end of the push rod 182 away from the end connected to the cylinder 181. The push rod 182 is driven by the cylinder 181 and controls the lifting and lowering of the support plate 12. The support plate 12 and the push rod 182 can be connected in any detachable manner such as a snap connection or a threaded connection, so as to facilitate the operator to quickly replace the support plate 12. When the powder tank 2 is replaced with a different diameter, the support plate 12 can be quickly removed and replaced to match the powder tank 2. Therefore, in this embodiment, no specific restrictions are made on the detachable connection between the support plate 12 and the push rod 182.

[0043] Reference Figure 2 and Figure 3 The support plate 12 is provided with a limiting opening 121 for the powder tank 2 to be inserted into. The limiting opening 121 of this embodiment is U-shaped and matches the shape of the outer wall of the powder tank 2. A baffle 13 is vertically fixedly connected to the side of the support plate 12 close to the frame 11. The baffle 13 is circumferentially arranged at the edge of the limiting opening 121. A guide plate 14 is fixedly connected to the side of the baffle 13 away from the support plate 12. The guide plate 14 in this embodiment is arranged in a trumpet shape and tilted toward the outside of the limiting opening 121.

[0044] Reference Figure 2 and Figure 4 , a limiting rod 15 is rotatably connected to one side of the support plate 12, and the rotation direction of the limiting rod 15 is in the same plane as the support plate 12. When the powder tank 2 is inserted into the limiting opening 121 of the support plate 12, the limiting rod 15 is rotated to enclose the limiting opening 121, so that the outer wall of the powder tank 2 abuts against the support plate 12 and the limiting rod 15. In this embodiment, a groove 151 is provided on the side of the limiting rod 15 for abutting against the powder tank 2, and the curvature of the groove 151 matches the outer wall of the powder tank 2.

[0045] The support plate 12 is fixedly connected to a limiting block 16 on a side away from the limiting plate, and a limiting groove 161 for the limiting rod 15 to be inserted into is provided on the side away from the supporting plate 12. Magnetic blocks 162 for mutual adsorption are provided on the side wall of the limiting rod 15 and the limiting block 16, and the magnetic block 162 on the limiting block 16 is provided in the limiting groove 161. When the end of the limiting rod 15 away from the rotational connection with the support plate 12 is inserted into the limiting groove 161, the limiting rod 15 and the limiting block 16 are fixed by magnetic attraction through the magnetic block 162.

[0046] A traction rope 17 for pulling the limiting rod 15 to rotate is passed through a side of the limiting rod 15 away from the rotatable connection with the support plate 12 , and the traction rope 17 is fixedly connected to the limiting rod 15 .

[0047] The implementation principle of the powder tank 2 docking mechanism of the embodiment of the present application is as follows: the airflow mill 3 is arranged on the support 4, and the powder tank 2 is placed on the ground and lifted by the crane 5. When the discharge port of the powder tank 2 is lifted to the same plane as the airflow mill 3, the crane 5 drives the powder tank 2 to translate through the slide rail and is inserted into the limit opening 121 of the support plate 12. During the lifting process, the powder tank 2 passes through the guide plate 14 and the baffle plate 13 in sequence. When the powder tank 2 passes through the guide plate 14, the shaking of the powder tank 2 is gradually reduced by the guiding effect. The baffle plate 13 can increase the contact area between the support plate 12 and the powder tank 2, and improve the supporting effect of the support plate 12 on the powder tank 2. When the powder tank 2 is inserted into the limiting opening 121 of the support plate 12, the outer wall of the powder tank 2 and the baffle 13 abut against each other to prevent the powder tank 2 from shaking when docking with the air flow mill 3. The traction rope 17 is pulled to make the limiting rod 15 inserted into the limiting groove 161 of the limiting block 16 and fixed by magnetic attraction, thereby improving the support and fixing effect of the support plate 12 on the powder tank 2.

[0048] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
