Description

Technical Field

[0001] The embodiments disclosed herein relate to the technical field of insulating board production, and more specifically, to a multi-channel batching machine for insulating board production. Background Technology

[0002] In the production of insulation boards, the accuracy and efficiency of the batching process directly affect the insulation performance and structural strength of the boards. Currently, traditional batching machines mostly adopt a single-channel feeding structure, which requires the sequential addition and mixing of different raw materials, making it difficult to meet the needs of simultaneous batching of multiple components in insulation board production.

[0003] This single-channel design has significant drawbacks: low feeding efficiency, requiring different raw materials to be added at different times, which prolongs the batching cycle, especially in large-scale production, affecting overall processing efficiency; raw materials are prone to stratification due to gravity within a single channel, with denser raw materials entering the mixing chamber first, making it difficult for them to quickly blend with the subsequently added lighter raw materials, resulting in insufficient mixing uniformity; thirdly, the fixed flow rate of raw materials within a single channel makes it impossible to adjust the feeding rate according to the characteristics of different raw materials (such as particle size and flowability), which can easily lead to local accumulation or poor conveying, further exacerbating the poor mixing effect.

[0004] Furthermore, traditional batching machines have simple mixing structures, often relying on a single stirring shaft. This makes it difficult to break up agglomerates of common fiber and powder raw materials used in insulation board production, thus affecting the performance stability of the final board. These problems make existing equipment insufficient to meet the high-efficiency and mixing precision requirements of high-quality insulation board production, necessitating a new type of batching machine with multi-channel collaborative operation. Utility Model Content

[0005] To overcome the above-mentioned defects, the embodiments of this disclosure provide a multi-channel batching machine for insulating board production, which solves the technical problems of low feeding efficiency, the need to feed different raw materials at different times, and the extension of the batching cycle, especially in large-scale production, which affects the overall processing efficiency.

[0006] According to one aspect, at least one embodiment of this disclosure provides a multi-channel batching machine for producing insulating boards, comprising:

[0007] The system comprises a base plate, a main frame, a fixed sleeve, and a rolling tank. The main frame is fixed to the base plate, the fixed sleeve is fixed to the main frame, and the rolling tank is horizontally rotatably connected to one end of the fixed sleeve.

[0008] A feeding assembly is disposed on the fixed housing;

[0009] A stirring assembly is disposed within the fixed sleeve and the rolling tank;

[0010] A discharge assembly is disposed on the rolling tank and the bottom plate;

[0011] The feeding assembly includes several feeding pipes, all of which are fixed to the top of the fixed housing. A conveying auger is installed inside each feeding pipe, and a feeding hopper is provided at the top of each feeding pipe.

[0012] As a further technical solution, the stirring assembly includes an inner shaft, which is rotatably connected to the fixed sleeve and the rolling tank. Several pusher frames are fixedly connected to the inner shaft, and the pusher frames are generally in the shape of a gate.

[0013] As a further technical solution, a number of dispersing rods are fixed on the inner end face of the pusher frame, a number of turning plates are arranged around the inner wall of the rolling tank, and a pair of annular sleeves are arranged inside the main frame.

[0014] As a further technical solution, a sliding protrusion is provided around the outer surface of the rolling tank, and the rolling tank is slidably connected to the annular sleeve through the sliding protrusion. An anti-slip layer is provided around the outer surface of the rolling tank, and a drive wheel that is driven by electricity is provided on the main frame, and the drive wheel is in contact with the surface of the anti-slip layer.

[0015] As a further technical solution, the discharge assembly includes a discharge port, which is opened on the surface of the rolling tank. A sealing cover is fixedly connected to the outer end of the discharge port by bolts, and a centralized sliding hopper is provided on the surface of the bottom plate.

[0016] As a further technical solution, the cross-section of the turning plate has an L-shaped structure.

[0017] As a further technical solution, a shield is provided on the inner side of the fixed sleeve, the shield is rotatably fitted on the outside of the inner shaft, and the cross-section of the shield is conical.

[0018] As a further technical solution, both ends of the rolling tank are inclined structures.

[0019] The beneficial effects of the embodiments disclosed herein are as follows:

[0020] In this disclosure, the feeding assembly solves the problems of low efficiency and time-sharing raw material feeding in traditional single-channel feeding by using multi-channel feeding pipes and independent conveying augers. Each feeding pipe can simultaneously transport different raw materials, and the feeding ratio and speed can be precisely controlled by adjusting the auger speed, avoiding raw material stratification and meeting the needs of insulation board production for simultaneous batching of multi-component raw materials. The funnel design of the feeding hopper facilitates material feeding, and the independent channels reduce cross-contamination of raw materials, significantly shortening the batching cycle, improving the continuity and efficiency of large-scale production, and laying a uniform foundation for subsequent mixing processes.

[0033] like Figures 1-4 As shown, it illustrates a multi-channel batching machine for producing insulating boards according to an embodiment of this disclosure, comprising:

[0034] The system comprises a base plate 1, a main frame 2, a fixed sleeve 3, and a rolling tank 4. The main frame 2 is fixed on the base plate 1, the fixed sleeve 3 is fixed on the main frame 2, and the rolling tank 4 is horizontally rotatably fitted into one end of the fixed sleeve 3.

[0035] Feeding assembly 5, which is disposed on the fixed sleeve 3;

[0036] A stirring assembly 6 is disposed within the fixed sleeve 3 and the rolling tank 4.

[0037] Discharge assembly 7 is disposed on the rolling tank 4 and the bottom plate 1;

[0038] The feeding assembly 5 includes several feeding pipes 5-1, all of which are fixed to the top of the fixed housing 3. A conveying auger 5-2 is installed inside each feeding pipe 5-1, and a feeding hopper 5-3 is provided at the top of each feeding pipe 5-1.

[0039] In some examples, to achieve multi-channel feeding, a feeding assembly 5 is designed. This assembly includes several feeding pipes 5-1 on the top of the fixed housing 3, which are arranged in an array and parallel to each other. The ends of the pipes are connected to the inside of the rolling tank 4 to form independent raw material conveying paths. The conveying auger 5-2 in each feeding pipe 5-1 is rotatably connected by a bearing, and its upper end is connected to the output shaft of the drive motor, allowing independent control of the rotation speed.

[0040] The feed hopper 5-3 at the top of the feed pipe 5-1 has a funnel-shaped structure and is vertically connected to the pipe for easy raw material feeding. Different raw materials are added to their corresponding feed hoppers 5-3. After the conveying auger 5-2 is started, the raw materials are conveyed along the pipe to the rolling tank 4 by the auger blades. Since each feed pipe 5-1 is independently controlled, the feed amount and feed speed of each raw material can be precisely controlled by adjusting the speed of the conveying auger 5-2. This allows for the synchronous addition of multi-component raw materials in proportion, meeting the requirements of batching accuracy in insulation board production and avoiding the deviation in raw material mixing ratio caused by single-channel feeding.

[0041] like Figures 1-4 As shown in the figure, the stirring assembly 6 in this embodiment includes an inner shaft 6-1, which is rotatably connected to the fixed housing 3 and the rolling tank 4. Several pusher frames 6-2 are fixedly connected to the inner shaft 6-1. The pusher frames 6-2 are generally door-shaped. Several dispersing rods 6-3 are fixed on the inner end face of the pusher frames 6-2. Several turning plates 6-4 are arranged around the inner wall of the rolling tank 4. A pair of annular sleeves 6-5 are arranged inside the main frame 2. A sliding protrusion 6-6 is arranged around the outer surface of the rolling tank 4. The rolling tank 4 is slidably connected to the annular sleeves 6-5 through the sliding protrusion 6-6. An anti-slip layer 6-7 is arranged around the outer surface of the rolling tank 4. A drive wheel 6-8 driven by electricity is arranged on the main frame 2. The drive wheel 6-8 is in contact with the surface of the anti-slip layer 6-7.

[0042] In some examples, to achieve efficient mixing, a stirring assembly 6 is designed. This assembly is fixed to the housing 3 and the inner shaft 6-1 inside the rolling tank 4, which is rotatably supported by bearings. Several portal-shaped pushers 6-2 on the shaft are evenly distributed along the axial direction, and the dispersing rods 6-3 inside the pushers 6-2 are arranged in an alternating pattern. The turning plate 6-4 on the inner wall of the rolling tank 4 forms a 45° angle with the axis and rotates synchronously with the tank wall.

[0043] The annular sleeve 6-5 inside the main frame 2 is fixed by bolts. The sliding protrusion 6-6 on the outer surface of the rolling tank 4 slides and fits against the inner wall of the annular sleeve 6-5, providing rotational support for the rolling tank 4. The anti-slip layer 6-7 on the outer surface of the rolling tank 4 is made of a high-friction coefficient material and fits tightly against the drive wheel 6-8 on the main frame 2. When the drive wheel 6-8 is electrically driven to rotate, it drives the rolling tank 4 to rotate around the annular sleeve 6-5 through friction.

[0044] During operation, the inner shaft 6-1 drives the pusher frame 6-2 and the dispersing rod 6-3 to rotate. The pusher frame 6-2 pushes the raw material along the axial direction, and the dispersing rod 6-3 breaks up any clumps of raw material. At the same time, the rolling tank 4 rotates under the drive wheel 6-8, and the tipping plate 6-4 flips the raw material near the tank wall upwards. The two movements create a stirring effect, ensuring that the raw material entering through multiple channels is fully mixed under the synergistic action of pushing, dispersing, and tipping, thus solving the problem of uneven mixing caused by density differences in the insulating board raw material.

[0045] like Figures 1-4 As shown in the figure, the discharge assembly 7 in this embodiment includes a discharge port 7-1, which is opened on the surface of the rolling tank 4. A sealing cover 7-2 is fixedly connected to the outer end of the discharge port 7-1 by bolts, and a centralized sliding hopper 7-3 is provided on the surface of the bottom plate 1.

[0046] In some examples, to achieve stable material discharge, a discharge assembly 7 is designed. This assembly includes a discharge port 7-1 located on the surface of the rolling tank 4 at the lowest point of the tank, communicating with the interior. The outer end of the sealing cover 7-2 is tightly fitted to the tank wall with bolts, and a rubber sealing ring is installed inside the cover to ensure a tight seal. The centralized sliding hopper 7-3 on the surface of the bottom plate 1 is located below the rolling tank 4, is inclined, and its lower end connects to the subsequent process equipment.

[0047] After the raw materials are mixed, loosen the fixing bolts of the sealing cover 7-2, rotate the rolling tank 4 so that the discharge port 7-1 faces downwards, and the mixed raw materials fall from the discharge port 7-1 into the centralized sliding hopper 7-3 under the action of gravity, and slide along the inclined hopper surface into the next process. The bolt connection of the sealing cover 7-2 ensures the sealing during mixing and facilitates quick opening; the inclined design of the centralized sliding hopper 7-3 accelerates the flow of raw materials and avoids residue accumulation. This component, through the precise setting of the discharge port 7-1, the reliable sealing of the sealing cover 7-2, and the efficient conveying of the sliding hopper, achieves rapid discharge of mixed raw materials and improves the continuous working efficiency of the batching machine.

[0048] For example, such as Figure 4 As shown, the cross-section of the flipping plate 6-4 has an L-shaped structure.

[0049] In some examples, the L-shaped structure of the cross-section of the turning plate 6-4 has its vertical side fixed to the inner wall of the rotating tank 4, while its horizontal side faces inward. When the rotating tank 4 rotates, the horizontal side can lift more raw materials upward and turn them over, while the vertical side prevents the raw materials from slipping down, enhancing the turning effect. The L-shaped structure allows the raw materials to form a stronger collision and mixing during turning, improving the blending degree of different raw materials. Together with other components of the stirring assembly 6, it further solves the problem of uneven mixing.

[0050] For example, such as Figure 3 As shown, a shield 8 is provided on the inner side of the fixed sleeve 3. The shield 8 is rotatably mounted on the outside of the inner shaft 6-1. The shield 8 has a conical cross-section.

[0051] In some examples, the conical shield 8 inside the fixed housing 3 has its large-diameter end facing the rotating tank 4, while its small-diameter end is rotatably fitted with the inner shaft 6-1. It prevents raw materials falling into the feed pipe 5-1 from directly impacting the inner shaft 6-1, guiding the raw materials to disperse towards the center of the rotating tank 4 and preventing material accumulation at the tank opening. The conical structure reduces material adhesion while not affecting the rotation of the inner shaft 6-1, ensuring smooth connection between the feeding and mixing processes.

[0052] For example, such as Figure 3 As shown, both ends of the rolling tank 4 are inclined structures.

[0053] In some examples, the inclined structures at both ends of the rotating tank 4 gradually narrow from the middle to both ends. This design causes the raw materials to gather towards the middle as they rotate inside the tank, reducing residue at both ends. At the same time, the inclined surfaces guide the raw materials to form a circulating flow as the tank rotates, enhancing contact with the pusher 6-2 and the dispersing rod 6-3, improving mixing uniformity, and facilitating the collection of raw materials towards the discharge port 7-1 during discharge.

[0054] In actual use: Different raw materials are placed into multiple feed hoppers 5-3 of the feeding assembly 5, and the conveying auger 5-2 in the corresponding feed pipe 5-1 is started to synchronously transport the raw materials to the rolling tank 4 in proportion. The drive wheel 6-8 drives the rolling tank 4 to rotate in the annular sleeve 6-5 through the anti-slip layer 6-7, and the inner shaft 6-1 rotates synchronously. The gantry pusher 6-2 pushes the raw materials axially, the dispersing rod 6-3 breaks up the clumps of raw materials, and the L-shaped tipping plate 6-4 flips the raw materials at the edge upwards as the rolling tank 4 rotates. The shield 8 guides the raw materials to gather in the middle of the tank to avoid accumulation at the tank opening. After mixing, the bolts of the sealing cover 7-2 are loosened, and the rolling tank 4 is rotated so that the discharge port 7-1 faces downward. The raw materials fall into the centralized sliding hopper 7-3 through the discharge port 7-1 and are transported to the next process along the inclined hopper surface. The inclined structure at both ends of the rolling tank 4 reduces raw material residue and completes the batching process.

Although this disclosure has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this disclosure without departing from the spirit and scope of the technical solutions of this disclosure, and all such modifications and substitutions should be covered within the scope of the claims of this disclosure.
