Description

Technical Field

[0001] This utility model relates to the technical field of water-based coating production equipment, and in particular to an automatic feeding device for the production of water-based coating heat insulation materials. Background Technology

[0002] In the field of building energy conservation and environmental protection materials, water-based coating-type thermal insulation materials are becoming a new favorite in the green building materials market due to their low VOC emissions, high thermal insulation performance and ease of construction. With the in-depth implementation of the dual-carbon strategy, the demand for high-performance environmentally friendly thermal insulation materials in fields such as building exterior wall insulation, cold chain logistics, and new energy equipment is growing exponentially.

[0003] In the process of using water-based coating production equipment, traditional feeding devices usually adopt a single-chamber design. During storage and transportation, powder is prone to agglomeration due to static conditions or changes in ambient humidity. This is especially true when handling difficult-to-disperse powders such as aluminum silicate and vitrified microspheres, where the agglomeration rate is high. Although existing technologies have attempted to solve this problem by adding a stirring device, most of them use a single-blade structure with a fixed rotation speed. This structure can only affect the powder on the surface of the storage chamber and cannot deeply address the agglomeration problem in the metering chamber and conveying pipeline. Consequently, it is inconvenient to continuously disperse the powder during the feeding process of difficult-to-disperse powders to prevent agglomeration.

[0004] Therefore, to address the aforementioned inconvenience in continuously dispersing and preventing agglomeration of difficult-to-disperse powders during the feeding process, an automatic feeding device for the production of water-based coating insulation materials can be designed. During the use of this water-based coating production device, the drive assembly can synchronously rotate the main and auxiliary stirring frames, preventing powder blockage at the inlet and maintaining powder flowability. Furthermore, due to the multiple sets of protrusions on the surface of the feeding auger, its rotational motion not only conveys and feeds the powder but also further disperses it during the feeding process, thereby improving the efficiency of subsequent processing steps. In summary, this device, through its dual-chamber design and dual anti-clogging mechanism, can reduce the failure rate and continuously disperse the powder during the feeding process, thus preventing agglomeration. Utility Model Content

[0005] In order to overcome the problem that most water-based coating production equipment adopts a single-blade structure with a fixed rotation speed, which can only affect the powder on the surface of the storage chamber and cannot deeply solve the problem of clumping in the metering chamber and conveying pipeline, it is inconvenient to continuously disperse the powder during the feeding process of difficult-to-disperse powder to prevent the powder from clumping.

[0006] The technical solution of this utility model is as follows: an automatic feeding device for the production of water-based coating thermal insulation materials, comprising a powder silo, a feeding hopper, a storage chamber, a metering chamber, a partition plate, a feed inlet, a feeding silo, a feeding auger, a stirring shaft, a feeding pipe, a main stirring frame, a secondary stirring frame, a drive assembly, and an anti-clogging assembly. A feeding hopper is fixedly installed on the top of the powder silo. A storage chamber is opened at the upper inner side of the powder silo, and a metering chamber is opened at the lower inner side of the powder silo. A partition plate is fixedly installed inside the powder silo. The left side of the partition plate... The powder silo has a feed inlet through the wall and a feed port through the left bottom wall. A feeding silo is fixedly installed on the bottom left side of the powder silo. A feeding auger is rotatably installed inside the feeding silo. A stirring shaft is rotatably installed inside the powder silo and is rotatably connected to the partition plate. A feeding pipe is installed through the bottom left side of the feeding silo. A drive assembly is installed at the bottom of the powder silo. A main stirring frame is fixedly installed on the upper side wall of the stirring shaft. A secondary stirring frame is fixedly installed on the lower side wall of the stirring shaft. A sealing assembly is installed inside the powder silo.

[0007] Preferably, during the use of the water-based coating production device, when feeding the proportioned powder, activating the drive assembly can drive the feeding auger to rotate. The rotation of the feeding auger can then transport the powder to the feeding pipe on the left side, and finally, the powder is discharged from the feeding pipe. At the same time, the drive assembly can drive the main stirring frame and the auxiliary stirring frame to rotate synchronously. The rotation of the main stirring frame can stir and disperse the powder inside the storage chamber, and can prevent the powder from clogging at the inlet. Meanwhile, the rotation of the auxiliary stirring frame can stir and disperse the powder inside the metering chamber. Furthermore, it can prevent powder from clogging at the feed inlet, maintain powder flowability, and prevent powder from agglomerating. In addition, since the surface of the feeding auger is equipped with multiple sets of protrusions, the rotation of the feeding auger can not only transport and feed the powder, but also further disperse the powder during the feeding process, thereby improving the efficiency of subsequent processing steps. In summary, this device, through its dual-chamber design and dual anti-clogging mechanism, can reduce the failure rate, and during the feeding process of difficult-to-disperse powder, it can continuously disperse the powder, thereby preventing powder agglomeration.

[0008] Preferably, the main stirring rack is located inside the storage chamber, the auxiliary stirring rack is located inside the metering chamber, and two sets of feed inlets are provided, with another set of feed inlets extending through the top right side of the feeding hopper.

[0009] Preferably, the drive assembly includes a fixed housing, a drive motor, and a drive shaft. The fixed housing is fixedly installed at the bottom of the powder hopper, the drive motor is fixedly installed on the right side of the fixed housing, and the drive shaft is installed at the output end of the drive motor. The drive shaft is located inside the fixed housing.

[0010] Preferably, the drive assembly also includes a rotating bevel gear and a transmission bevel gear. The rotating bevel gear is fixedly installed on the side wall of the drive shaft, and the transmission bevel gear is fixedly installed at the lower end of the stirring shaft. The transmission bevel gear is located inside the fixed shell. The rotating bevel gear meshes with the transmission bevel gear, and the left end of the drive shaft is fixedly connected to the right end of the feeding auger.

[0011] Preferably, the sealing assembly includes a sealing disc, a feeding motor, and a main shaft. The inside of the feeding port is equipped with a matching sealing disc, the feeding motor is fixedly installed on the left wall of the powder hopper, the output end of the feeding motor is equipped with a main shaft, and the sealing disc is fixedly connected to the right end of the main shaft.

[0012] Preferably, the sealing assembly also includes a sealing plate, a feeding motor, and a driven shaft. The inside of the feed inlet is provided with matching sealing plates, the bottom of the left wall of the powder silo is fixedly provided with a feeding motor, the output end of the feeding motor is provided with a driven shaft, and the sealing plate is fixedly connected to the right end of the driven shaft.

[0013] Preferably, a quantitative scale is installed at the bottom of the powder silo, and a control actuator is fixedly installed on the right side of the bottom of the powder silo.

[0014] The beneficial effects of this utility model are:

[0015] During the operation of the water-based coating production equipment, when feeding the pre-mixed powder, activating the drive assembly rotates the feeding auger. The auger's rotation conveys the powder to the feeding pipe on the left, from which it is ultimately discharged. Simultaneously, the drive assembly drives the main and auxiliary mixing frames to rotate synchronously. The main mixing frame's rotation agitates and disperses the powder inside the storage chamber, preventing blockage at the inlet. Meanwhile, the auxiliary mixing frame's rotation agitates and disperses the powder inside the metering chamber. Furthermore, it can prevent powder from clogging at the feed inlet, maintain powder flowability, and prevent powder from clumping. In addition, since the surface of the feeding auger is equipped with multiple sets of protrusions, the rotation of the feeding auger can not only transport and feed the powder, but also disperse the powder a second time during the feeding process, thereby improving the efficiency of subsequent processing steps. In summary, this device, through its dual-chamber design and dual anti-clogging mechanism, can reduce the failure rate. Moreover, during the feeding process of difficult-to-disperse powder, it can continuously disperse the powder, thereby preventing powder from clumping. Attached Figure Description

[0025] Please see Figure 2 and Figure 5The sealing assembly includes a sealing disc 19, a feeding motor 20, and a main shaft 21. A matching sealing disc 19 is installed inside the feeding port 6. The feeding motor 20 is fixedly installed on the left wall of the powder silo 1. The output end of the feeding motor 20 is connected to the main shaft 21. The sealing disc 19 is fixedly connected to the right end of the main shaft 21. When the feeding motor 20 is started, its output end can drive the sealing disc 19 to rotate to a preset angle via the main shaft 21. After the sealing disc 19 rotates, the feeding port 6 is opened, and the powder then enters the metering chamber 4 through the feeding port 6 under gravity. The sealing assembly also includes a sealing plate 22, a feeding motor 23, and a driven shaft 24. A matching sealing plate 22 is installed inside the feeding port 7. The feeding motor 23 is fixedly installed at the bottom of the left wall of the powder silo 1. The output end of the feeding motor 23 is provided with a driven shaft 24. The sealing plate 22 is fixedly connected to the right end of the driven shaft 24. When the feeding motor 23 is started, its output end can drive the sealing plate 22 to rotate to a preset angle through the driven shaft 24. After the sealing plate 22 rotates, the feed port 7 can be opened. The powder then enters the interior of the feeding hopper 8 through the feed port 7 under the action of gravity. A quantitative scale 25 is provided at the bottom of the powder hopper 1. A control actuator 26 is fixedly provided on the right side of the bottom of the powder hopper 1. The quantitative scale 25 can transmit the weight data of the powder inside the quantitative chamber 4 to the control actuator 26. When the powder inside the quantitative chamber 4 reaches the raw material ratio value, the feeding motor 20 is started to drive the sealing plate 19 to reverse through the main shaft 21, and then the feed port 6 can be sealed.

[0026] When using the water-based coating production equipment, when storing powder materials, the operator first puts the powdered raw materials into the storage chamber 3 through the top feed hopper 2;

[0027] When it is necessary to feed powder in a quantitative manner, firstly, start the feeding motor 20. Its output end can drive the sealing plate 19 to rotate to a preset angle through the main shaft 21. After the sealing plate 19 rotates, the feeding port 6 can be opened. The powder then enters the inside of the quantitative chamber 4 through the feeding port 6 under the action of gravity. At this time, the weight data of the powder inside the quantitative chamber 4 can be transmitted to the control actuator 26 through the quantitative scale 25. When the powder inside the quantitative chamber 4 reaches the raw material ratio value, start the feeding motor 20 to drive the sealing plate 19 to reverse through the main shaft 21, and then the feeding port 6 can be sealed.

[0028] When feeding the proportioned powder, the feeding motor 23 is started. Its output end can drive the sealing plate 22 to rotate to a preset angle through the shaft 24. After the sealing plate 22 rotates, the feeding port 7 can be opened. The powder then enters the feeding hopper 8 through the feeding port 7 under the action of gravity. At the same time, the drive motor 15 is started. The output end of the drive motor 15 can drive the feeding auger 9 to rotate through the drive shaft 16. The rotation of the feeding auger 9 can transport the powder to the feeding pipe 11 on the left side. Finally, the powder is discharged from the feeding pipe 11.

[0029] At the same time, the drive shaft 16 can drive the rotating bevel gear 17 to rotate synchronously. Since the rotating bevel gear 17 meshes with the transmission bevel gear 18, the rotation of the rotating bevel gear 17 can drive the transmission bevel gear 18 to rotate. The transmission bevel gear 18 can drive the stirring shaft 10 to rotate. The stirring shaft 10 can drive the main stirring frame 12 and the auxiliary stirring frame 13 to rotate synchronously.

[0030] The rotation of the main stirring frame 12 can stir and disperse the powder inside the storage chamber 3. When the powder passes through the inlet 6, the rotation of the main stirring frame 12 can prevent the powder from clogging at the inlet 6. At the same time, the rotation of the auxiliary stirring frame 13 can stir and disperse the powder inside the metering chamber 4. When the powder passes through the inlet 7, the rotation of the auxiliary stirring frame 13 can prevent the powder from clogging at the inlet 7, maintain the flowability of the powder, and prevent the powder from clumping.

[0031] In addition, since the surface of the feeding auger 9 is provided with multiple sets of protrusions, the rotation of the feeding auger 9 can not only convey and feed the powder, but also break up the powder a second time during the feeding process to prevent the powder from clumping, thereby improving the efficiency of subsequent processing steps.

[0032] In summary, this device, through its dual-chamber design and dual anti-clogging mechanism, can reduce the failure rate. Furthermore, during the feeding process of difficult-to-disperse powders, it can continuously disperse the powders, thereby preventing powder agglomeration.

[0033] Through the above steps, during the use of the water-based coating production device, when feeding the proportioned powder, activating the drive assembly can drive the feeding auger 9 to rotate. The rotation of the feeding auger 9 can then transport the powder to the feeding pipe 11 on the left side, and finally, the powder is discharged from the feeding pipe 11. At the same time, the drive assembly can drive the main stirring frame 12 and the auxiliary stirring frame 13 to rotate synchronously. The rotation of the main stirring frame 12 can stir and disperse the powder inside the storage chamber 3, and can prevent the powder from clogging at the inlet 6. Meanwhile, the rotation of the auxiliary stirring frame 13 can stir and disperse the powder inside the metering chamber 4. The internal powder is stirred and dispersed, preventing it from clogging at the feed inlet 7, maintaining powder flowability, and preventing powder agglomeration. In addition, because the surface of the feeding auger 9 is equipped with multiple sets of protrusions, the rotation of the feeding auger 9 can not only transport and feed the powder, but also disperse the powder a second time during the feeding process, thereby improving the efficiency of subsequent processing steps. In summary, this device, through its dual-chamber design and dual anti-clogging mechanism, can reduce the failure rate, and during the feeding of difficult-to-disperse powder, it can continuously disperse the powder, thereby preventing powder agglomeration.

[0034] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
