Description

Technical Field

[0001] This application relates to the field of mixing equipment technology, and in particular to a plastic raw material mixing system. Background Technology

[0002] Currently, plastic granules are typically produced using a granulation machine. Based on the performance requirements of the granules, various plastic raw materials are mixed and stirred before being fed into the granulator for granulation, thus obtaining the desired plastic granules. The current mixing method in production involves manually feeding all raw materials into the mixer at once. However, with improvements in plastic manufacturing processes, it is often necessary to heat and dry multiple plastic raw materials before mixing them with auxiliary materials such as plasticizers. Manual mixing suffers from cumbersome steps and low mixing efficiency. Utility Model Content

[0003] To address the aforementioned technical problems, this application provides a plastic raw material mixing system, including a mounting frame, a support frame fixed on the mounting frame, and a drying hopper disposed on the top of the support frame. A mixing tank is disposed on the mounting frame on one side of the support frame, and a stirring assembly extending into the top of the mixing tank is disposed therein. A storage tank is disposed on the mounting frame and is connected to the mixing tank. A feeding assembly is disposed at the bottom of the drying hopper, and the end of the feeding assembly is connected to the mixing tank.

[0004] Preferably, the feeding assembly includes a feeding barrel connected to the bottom of the drying hopper, a first driving member disposed at one end of the feeding barrel, and a feeding screw connected to the driving end of the first driving member disposed inside the feeding barrel.

[0005] Preferably, the top of the support frame is connected to the drying hopper via a pressure sensor, and a bearing connecting seat is provided on the support frame, through which the feeding bucket is rotatably mounted on the support frame.

[0006] Preferably, the mounting frame is provided with a clamping component, which clamps the outer periphery of the mixing barrel.

[0007] Preferably, the clamping assembly includes a mounting base, a clamping block hinged to the mounting base, and an adjusting rod disposed on the mounting base, the adjusting rod being used to loosen or clamp the clamping block on the mixing barrel.

[0008] Preferably, a caster wheel is provided at the bottom of the feeding hopper, and a guide plate is provided at the top of the mounting base, with the caster wheel rotatably mounted on the guide plate.

[0009] Preferably, a column is provided on the mounting frame on one side of the mixing tank, and guide rails are provided around the column. A lifting block is fitted around the outer periphery of the column, and the lifting block is rolled and engaged with the guide rails by rollers. The stirring assembly is connected to the lifting block.

[0010] Preferably, a feed inlet is provided at the top of the drying hopper, and a sealing cover for opening or closing the feed inlet is provided at the feed inlet. A dryer connected to the sealing cover is also provided on the mounting frame.

[0011] As can be seen from the above, the following beneficial effects can be obtained by applying the method provided in this application: By fixing a support frame on the mounting frame and setting a drying hopper on the top of the support frame, raw materials that need to be dried in advance are put into the drying hopper for drying treatment. A storage tank is set on the mounting frame for feeding raw materials that do not need to be dried. The storage tank is connected to the mixing tank, so the raw materials in the storage tank can be transported to the mixing tank. A feeding component is set at the bottom of the drying hopper, and the end of the feeding component is connected to the mixing tank. So the dried raw materials in the drying hopper are transported to the mixing tank through the feeding component. A stirring component is set at the top of the mixing tank and extends into it.

[0017] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0018] Example

[0019] To address the aforementioned technical problems, this embodiment provides a plastic raw material mixing system, such as... Figure 1-2 As shown, the system includes a mounting frame 10, a support frame 20 fixed on the mounting frame 10, and a drying hopper 30 located on top of the support frame 20. Raw materials requiring pre-drying are fed into the drying hopper 30 for drying. A storage tank 60 is provided on the mounting frame 10 for feeding raw materials that do not require drying. The storage tank 60 is connected to a mixing tank 40, allowing the raw materials in the storage tank 60 to be conveyed into the mixing tank 40. A feeding assembly 70 is provided at the bottom of the drying hopper 30, with its end connected to the mixing tank 40. The dried raw materials in the drying hopper 30 are then conveyed into the mixing tank 40 via the feeding assembly 70. A stirring assembly 50 is provided at the top of the mixing tank 40, extending into it. The stirring assembly 50 uniformly stirs all the raw materials inside the mixing tank 40, thereby achieving automatic mixing of raw materials without the need for manual feeding, improving mixing efficiency, and thus improving the efficiency of automated production.

[0020] Specifically, such as Figure 3 As shown, the feeding assembly 70 includes a feeding barrel 72 connected to the bottom of the drying hopper 30, and a first driving member 71 disposed at one end of the feeding barrel 72. A feeding screw connected to the driving end of the first driving member 71 is disposed inside the feeding barrel 72. The end of the feeding barrel 72 is connected to the mixing barrel 40. For example, the first driving member 71 is a motor, and its driving end is connected to the feeding screw inside the feeding barrel 72. Thus, after the raw material from the drying hopper 30 enters the feeding barrel 72, the first driving member 71 drives the feeding screw to rotate, thereby conveying the raw material to the mixing barrel 40.

[0021] Furthermore, in some embodiments, the top of the support frame 20 can be connected to the drying hopper 30 via a pressure sensor 21. A bearing connecting seat 22 is provided on the support frame 20, and the feeding hopper 72 is rotatably mounted on the support frame 20 via the bearing connecting seat 22. The end of the feeding hopper 72 is connected to the mixing hopper 40 via a connecting pipe. After the connecting pipe is disassembled, the feeding hopper 72 is separated from the mixing hopper 40 by rotating the feeding hopper 72. Thus, the mixing hopper 40 can be periodically removed from the mounting frame 10 for cleaning.

[0022] In the above scheme, the storage tank 60 is used for feeding raw materials that do not require drying. The storage tank 60 is connected to the mixing tank 40, so the raw materials in the storage tank 60 can be transported to the mixing tank 40. Multiple feed pipes 61 are provided on one side of the storage tank 60, and the feed pipes 61 are connected to other feeding equipment. Auxiliary raw materials that do not require heating enter the storage tank 60 through the feed pipes 61, and are then transported to the mixing tank 40 through the storage tank 60. The bottom of the storage tank 60 is connected to the mixing tank 40 through a pipe. An air valve switch 62 can be provided at the bottom of the storage tank 60 to control the start and stop of feeding.

[0023] Furthermore, the mixing assembly 50 includes mixing blades extending into the mixing tank 40 and a drive motor positioned above the mixing tank 40. The drive motor drives the mixing blades to rotate, thereby mixing the raw materials inside the mixing tank 40. A discharge pipe is provided at the bottom of the mixing tank 40, through which the dried raw materials can be discharged. To prevent the mixing tank 40 from shaking violently during the mixing process, a clamping assembly 80 is provided on the mounting frame 10. The clamping assembly 80 clamps the mixing tank 40 to its outer periphery, thereby securing the mixing tank 40 in place.

[0024] Specifically, such as Figure 2-3 As shown, the clamping assembly 80 includes a mounting base 81, clamping blocks 83 hinged to the mounting base 81, and an adjusting rod 82 disposed on the mounting base 81. The adjusting rod 82 is used to loosen or clamp the clamping blocks 83 onto the mixing tank 40. The mounting base 81 is fixedly mounted on the mounting frame 10. By rotating the adjusting rod 82, the two clamping blocks 83 rotate relative to each other on the mounting base 81, thereby clamping the two clamping blocks 83 onto both sides of the mixing tank 40. In some other embodiments, the two clamping blocks 83 can also be driven by a cylinder to clamp and fix the mixing tank 40, thereby facilitating the clamping blocks 83 to clamp or loosen the mixing tank 40.

[0025] Furthermore, a movable wheel 73 is provided at the bottom of the feeding hopper 72, and a guide plate 74 is provided at the top of the mounting base 81. The movable wheel 73 is rolled on the guide plate 74. In the above scheme, the feeding hopper 72 is rotatably mounted on the support frame 20 through the bearing connecting seat 22. Thus, when the feeding hopper 72 rotates, the movable wheel 73 at the bottom of the feeding hopper 72 rotates along the guide plate 74, thereby supporting the feeding hopper 72.

[0026] In actual production, it is necessary to periodically disassemble the mixing assembly 50 and the mixing tank 40 for cleaning. Therefore, such as... Figure 3As shown, a column 91 is provided on the mounting frame 10 on one side of the mixing tank 40. Guide rails 92 are provided around the column 91. A lifting block 93 is sleeved on the outer periphery of the column 91. Rollers 94 are provided on the inner side of the lifting block 93. The lifting block 93 rolls with the guide rails 92 through the rollers 94. The stirring assembly 50 is connected to the lifting block 93. For example, the drive motor of the stirring assembly 50 is connected to the lifting block 93. The stirring assembly 50 can move up and down along the column 91 through the lifting block 93. The lifting block 93 can be driven to move up and down through the drive mechanism, thereby disengaging the stirring assembly 50 from the mixing tank 40. The mixing tank 40 can then be removed from the mounting frame 10 for cleaning, and the stirring blades of the stirring assembly 50 can be cleaned.

[0027] Furthermore, such as Figure 4 As shown, a feed inlet 31 is provided at the top of the drying hopper 30, and a sealing cover 32 is provided at the feed inlet 31 for opening or closing the feed inlet 31. A dryer 33 is also provided on the mounting frame 10 and connected to the sealing cover 32. When feeding, the sealing cover 32 can be opened to pour the raw material to be dried into the drying hopper 30 from the feed inlet 31. When working, the drying hopper 30 is closed, and hot air is then delivered through the dryer 33, passing through the sealing cover 32 and the feed inlet 31 into the drying hopper 30 to heat and dry the raw material.

[0028] In summary, the solution of this application involves fixing a support frame on an installation frame, setting a drying hopper at the top of the support frame, and feeding raw materials that need to be dried into the drying hopper for drying treatment. A storage tank is set on the installation frame for feeding raw materials that do not need to be dried. The storage tank is connected to a mixing tank, so the raw materials in the storage tank can be transported to the mixing tank. A feeding component is set at the bottom of the drying hopper, and the end of the feeding component is connected to the mixing tank. The dried raw materials in the drying hopper are then transported to the mixing tank through the feeding component. A stirring component is set at the top of the mixing tank and extends into it. The stirring component uniformly stirs all the raw materials inside the mixing tank, thereby realizing automatic mixing of raw materials without manual feeding, improving mixing efficiency, and thus improving the efficiency of automated production.

[0029] The embodiments described above do not constitute a limitation on the scope of protection of this technical solution. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the above embodiments should be included within the scope of protection of this technical solution.
