Technical Field

[0001] The invention relates to the field of processing and proportioning, in particular to an automatic proportioning system and a proportioning method for quick-setting thin strip alloy sheets. Background Art

[0002] One of the important functions of rare earth is permanent magnet, which is widely used in the production of permanent magnets. When making permanent magnets, they are generally formed by sintering and tempering. The preparation of quick-setting thin-strip alloy sheets is one of the process steps for sintering NdFeB permanent magnet materials. Therefore, the quick-setting thin-strip alloy sheets need to be prepared before sintering and tempering. Usually, the ingredients are mixed first. The existing mixing method usually uses multiple valve pipes for matching. This method will add many pipelines and valve body connecting lines, resulting in messy mixing position lines, which is inconvenient for subsequent maintenance and other operations. Summary of the Invention

[0003] The present invention aims to solve the problems existing in the prior art and provides the following technical solutions:

[0004] The automatic batching system for quick-setting thin alloy strips includes: a plurality of batching pipes, a discharge pipe and an adjustment component.

[0005] Specifically, the discharge end of the dispensing pipe is provided with a lifting block that can move along the pipe wall. The lifting block closes the discharge end of the dispensing pipe under the action of gravity. The adjusting component drives the feed end of the discharge pipe to be inserted into the discharge end of any one of the dispensing pipes to drive the lifting block to move along the pipe wall until the discharge end of the dispensing pipe is opened.

[0006] The opening is achieved by pushing the discharge pipe to lift the lifting block. This method can calculate the feeding amount according to the opening time. When no feeding is needed, the lifting block can be lowered to close the machine. The discharge pipe can be sent to different batching pipes for batching in conjunction with the adjustment component. This can meet the needs of automatic batching. In addition, no valve body is set on each pipeline, and there is no need for too many line connections, which reduces the difficulty of subsequent maintenance and makes the structure simpler and more convenient.

[0008] As an improvement of the above technical solution, a secondary pipe is connected to the bottom of the barrel at the center of the bracket, and the lower end of the secondary pipe has a branch pipe connected to the discharge pipe. The secondary pipe is used to operate on some components that need to be added separately or continuously in the middle.

[0009] As an improvement of the above technical solution, an annular inner cavity is provided on the inner wall of the discharge end of the dispensing pipe, and the lifting block is arranged inside the inner cavity. The lifting block can move along the inner wall of the inner cavity, and the outer edge of the lifting block fits into the interior of the inner cavity.

[0010] The inner cavity is used to limit the lifting block, and the lifting block can be lifted and lowered inside the inner cavity, thereby satisfying the lifting and lowering control of the lifting block to meet the opening and closing requirements.

[0011] As an improvement of the above technical solution, a dosing box is detachably fixed to the lower end of the dosing pipe, the inlet end of the discharge pipe has a convex tube, and the end of the convex tube away from the discharge pipe has an opening, and the outer surface of the dosing box is provided with a plurality of connecting grooves, and a limiting block is arranged inside the connecting groove. The lifting block fits with the limiting block under the action of gravity to close the discharge end of the dosing pipe, and the adjustment component drives the convex tube to insert into the gap between the limiting block and the connecting groove to push the lifting block to rise.

[0012] The lifting block is squeezed by adjusting the height of the convex tube. When the lifting block is raised, the material enters the convex tube from the opening to complete the batching. When the lifting block is lowered, the opening can be closed, thereby achieving the purpose of disconnecting the batching.

[0013] As an improvement of the above technical solution, the ingredient box includes a detachably connected upper barrel and a lower barrel, the connecting groove is opened on the upper surface of the upper barrel, and the adjustment component is arranged inside the lower barrel, separating the upper and lower barrels to facilitate subsequent maintenance and cleaning of internal materials.

The adjustment component is fixed to the surface of the connecting plate, and the adjustment component is fixed by the connecting plate in the lower barrel.

[0016] The position of the discharge pipe is switched by rotating the motor, and the lifting and lowering of the discharge pipe is controlled by the cylinder, thereby achieving the purpose of switching multiple discharge pipes distributed in a circular shape to meet usage needs.

[0017] As an improvement of the above technical solution, inclined portions are provided on both sides of the limit block, a penetrating middle groove is provided at the center of the lifting block, and a recess engaged with the inclined portion is provided at the bottom of the lifting block. When the recess engages with the inclined portion, the limit block closes the middle groove.

[0018] The coordination between the inclined portion and the notch ensures the stability of the material discharge and prevents the material from being squeezed and stuck inside.

[0019] An automatic batching method for quick-setting thin strip alloy sheets adopts any one of the automatic batching systems for quick-setting thin strip alloy sheets in the aforementioned technical solutions, comprising the following steps:

[0020] S1: Place the material receiving assembly at the discharge end of the discharge pipe, and then put one component of the quick-setting thin strip alloy sheet into each feeding pipe.

[0021] S2: The corresponding feed end of the discharging pipe is driven to be inserted into the discharge end of the dispensing pipe at the corresponding position through the adjusting component, so as to drive the lifting block to move along the pipe wall until the discharge end of the dispensing pipe is opened.

DETAILED DESCRIPTION

[0030] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0031] In the existing technology, quick-setting thin-strip alloy sheets need to be prepared before sintering and tempering the materials, usually by batching. The existing batching method usually uses multiple valve pipes. This method will add many pipelines and valve body connecting lines, resulting in messy batching positions and lines, which is inconvenient for subsequent maintenance and other operations.

[0032] Example 1

[0033] To resolve this issue, see Figure 1-6 , provides an automatic batching system for quick-setting thin strip alloy sheets, including: a plurality of batching pipes 12, a discharge pipe 24 and an adjustment component.

[0034] Specifically, the discharge end of the dispensing pipe 12 is provided with a lifting block 23 that can move along the pipe wall. The lifting block 23 closes the discharge end of the dispensing pipe 12 under the action of gravity. The adjusting component drives the feed end of the discharge pipe 24 to be inserted into the discharge end of any one of the dispensing pipes 12 to drive the lifting block 23 to move along the pipe wall until the discharge end of the dispensing pipe 12 is opened.

[0035] The discharge pipe 24 is adjusted to switch inside several batching pipes 12 by adjusting the component, and each time an extrusion force is provided to the lifting block 23 by inserting the discharge end of the batching pipe 12 until the lifting block 23 is pushed to a position where the batching pipe 12 cannot be closed. In this case, the material inside the batching pipe 12 can enter the discharge pipe 24, and the operation is performed according to different batching sequences. A component is placed inside each batching pipe 12, so that the material of the corresponding component can be added by connecting the batching pipe 12 with the discharge pipe 24, and the order of adding can be adapted according to the order of connection, and the amount of adding can be adapted according to the time of connection, which can meet the needs of use.

[0036] In one embodiment, see Figure 1, further comprising: a bracket 10 , a plurality of barrels 11 being fixed on the upper portion of the bracket 10 , each barrel 11 being communicated with a feeding end of a dispensing pipe 12 .

[0037] The bracket 10 provides overall support, and the barrel 11 is used to load the material. The material inside the barrel 11 can be dosed along the dosing pipe 12.

[0038] In one embodiment, see Figure 1-3 The bottom of the barrel 11 at the center of the bracket 10 is connected to a secondary pipe 13 , and the lower end of the secondary pipe 13 has a branch pipe 14 connected to the discharge pipe 24 .

[0039] When adding and mixing, some components may need to be continuously added during the process. In this case, in order to avoid affecting the constantly switching discharge pipe 24, an additional feeding pipeline is provided through the auxiliary pipe 13, and then the material is directly introduced into the root of the discharge pipe 24 through a branch pipe 14 with a smaller diameter. This not only ensures that the material is added to the inside of the discharge pipe 24, but also avoids the auxiliary pipe 13 from affecting the discharge pipe 24.

[0040] In one embodiment, see Figure 3 The inner wall of the discharge end of the dispensing pipe 12 is provided with an annular inner cavity 121, and the lifting block 23 is arranged inside the inner cavity 121. The lifting block 23 can move along the inner wall of the inner cavity 121, and the outer edge of the lifting block 23 is in contact with the inside of the inner cavity 121.

[0041] That is, the lifting block 23 can move inside the inner cavity 121, and the inner cavity 121 is an annular groove, which limits the lifting of the lifting block 23 to a linear movement along the tube wall. In this case, the lifting block 23 can be driven to change in height only by squeezing and pushing the discharge tube 24.

[0042] In one embodiment, see Figure 1 、 4 6. The lower end of the dispensing pipe 12 is detachably fixed with a dispensing box 20. The feeding end of the discharge pipe 24 has a protruding pipe 241. The end of the protruding pipe 241 away from the discharge pipe 24 has an opening 242. The outer surface of the dispensing box 20 is provided with a plurality of connecting grooves 211. The interior of the connecting groove 211 is provided with a limiting block 212. The lifting block 23 is fitted with the limiting block 212 under the action of gravity to close the discharge end of the dispensing pipe 12. The adjusting component drives the protruding pipe 241 to be inserted into the gap between the limiting block 212 and the connecting groove 211 to push the lifting block 23 to rise.

[0043] An inserted connection state is formed by the cooperation between the protruding tube 241 and the connecting groove 211. When the protruding tube 241 is inserted into the connecting groove 211, the lifting block 23 will be squeezed, causing the lifting block 23 to rise. In this case, the lifting block 23, which was originally in a closed state with the limit block 212, will move away from the limit block 212, thereby forming a gap between the limit block 212, and the material is dropped from the gap. The amount of the material dropped is determined according to the time of the material dropping.

[0044] In one embodiment, see Figure 4 The ingredient box 20 includes an upper barrel 21 and a lower barrel 22 that are detachably connected. The connecting groove 211 is opened on the upper surface of the upper barrel 21, and the adjusting component is arranged inside the lower barrel 22.

[0045] The batching box 20 is arranged into two layers, the upper and lower layers. This structure allows the batching box 20 to be easily disassembled. After long-term use, the structure can be disassembled and the internal structure can be inspected and cleaned, which is convenient to use.

[0046] In one embodiment, see Figure 4 A circular positioning groove 221 is provided on the upper surface of the lower barrel 22 , and a connecting plate 222 extending to the center of the positioning groove 221 is fixed on the inner wall of the positioning groove 221 , and the adjustment component is fixed to the surface of the connecting plate 222 .

[0047] The circular positioning groove 221 can provide a moving space for the discharge pipe 24 , so that the adjustment component is installed on the connecting plate 222 for adjustment operation, which can avoid the adjustment component from affecting the position of the discharge pipe 24 .

[0048] In one embodiment, see Figure 4-6 , several dispensing pipes 12 are distributed in a ring shape on the upper surface of the upper barrel 21, and the adjustment component includes a motor 223 fixed to the upper surface of the connecting plate 222, a mounting plate 224 fixed to the power end of the motor 223, and a cylinder 225 eccentrically arranged on the mounting plate 224 away from one end face of the motor 223, the power end of the cylinder 225 is connected to the positioning plate 226, and the discharge pipe 24 is arranged inside the positioning plate 226, and the discharge pipe 24 passes through and fits the inner wall of the positioning groove 221.

[0049] The motor 223 provides rotational power to drive the mounting plate 224 to rotate. When the mounting plate 224 rotates, the eccentrically arranged cylinder 225 will perform circular motion around the center position of the mounting plate 224. In this case, the discharge pipe 24 fixed on the positioning plate 226 can perform circular motion synchronously, ensuring that the discharge pipe 24 is always inside the positioning groove 221 and fits the inner wall of the positioning groove 221. In addition, since the dispensing pipes 12 are annularly distributed, in this case, the discharge pipe 24 that can perform circular motion can be adapted to the position of different dispensing pipes 12 in a rotating manner to achieve the purpose of switching positions. Combined with the extension and contraction of the cylinder 225, the operation of inserting and withdrawing the discharge pipe 24 from the inside of the dispensing pipe 12 can be controlled under corresponding position conditions, thereby achieving the purpose of switching the connection between the discharge pipe 24 and the dispensing pipe 12.

[0050] Since the material is always in an extruded state, part of the inside of the dispensing pipe 12 is solid material. In this case, the material may be squeezed and unable to be discharged. To solve this problem, please refer to Figure 4 and Figure 5 The limiting block 212 has inclined portions 213 on both sides, the lifting block 23 has a through middle groove 231 at the center, and the lifting block 23 has a notch 232 at the bottom that engages with the inclined portion 213. When the notch 232 engages with the inclined portion 213, the limiting block 212 closes the middle groove 231.

[0051] The inclined portion 213 is provided to discharge the material from both sides of the limiting block 212, thereby avoiding the problem of material being squeezed and unable to be discharged.

[0052] Example 2

[0053] In order to cooperate with the first embodiment, a method for automatically batching quick-setting thin strip alloy sheets is provided, which uses any one of the automatic batching systems for quick-setting thin strip alloy sheets in the first embodiment, including the following steps:

[0054] S1: Place a material receiving assembly at the discharge end of the discharge pipe 24, and then put one component of the quick-setting thin strip alloy sheet into each distribution pipe 12.

[0055] The material receiving assembly is used to receive the material dispensed from the discharge pipe 24. The material receiving assembly can be a device such as a stirring kettle for subsequent processing of the material.

[0056] S2: The corresponding feed end of the discharge pipe 24 is driven by the adjustment component to be inserted into the discharge end of the distribution pipe 12 at the corresponding position, so as to drive the lifting block 23 to move along the pipe wall until the discharge end of the distribution pipe 12 is opened.

[0057] S3: Repeat step S2 according to the order of adding materials until all components are added, and drive the discharge pipe 24 away from the mixing pipe 12.

[0058] The discharge pipe 24 is connected to the batching pipe 12 through the adjustment component for batching. When the batching is completed, the connection between the discharge pipe 24 and the batching pipe 12 is disconnected. In this case, the lifting block 23 closes the discharge end of the batching pipe 12, thereby avoiding the problem of continued leakage of materials.

[0059] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same.
