Description

Technical Field

[0001] This utility model belongs to the field of plastic granulation technology, and specifically relates to a plastic granulator with an automatic raw material mixing function. Background Technology

[0002] In the plastics processing industry, plastic granulators are core equipment used to mix plastic raw materials (such as polyethylene and polypropylene granules) with functional additives (such as antioxidants, toughening agents, and color masterbatches), then heat, melt, extrude, and granulate them into standardized plastic granules. They are widely used in the pretreatment of plastic raw materials in packaging, building materials, and automotive parts industries. The quality of plastic granulated products is directly related to the accuracy of the raw material ratio and the uniformity of mixing. For example, insufficient antioxidant addition will lead to a decrease in the aging resistance of plastic granules, uneven color masterbatch ratio will result in inconsistent color depth of the finished granules, and uneven melting of raw materials will cause "poor plasticization" during the granulation process, resulting in defects such as internal air bubbles and rough surfaces in the granules, seriously affecting the processing quality of downstream products.

[0003] However, existing plastic granulators still have significant technical shortcomings in the raw material feeding and mixing stages, making it difficult to meet the production requirements of high precision and high uniformity. Raw material proportioning relies on manual operation, resulting in low accuracy and efficiency. Operators must first weigh different raw materials separately using a platform scale according to process requirements, and then feed them sequentially into the granulator's hopper. This process is not only time-consuming and labor-intensive, but also prone to inaccurate proportions due to manual weighing errors and disordered feeding sequences. Especially in small-batch, multi-batch production scenarios, frequent formula changes further amplify proportioning errors, leading to significant differences in the performance of plastic granules between different batches. Furthermore, the large differences in particle size among the granules can easily lead to uneven melting, directly causing localized raw material concentration imbalances within the extruder. The resulting plastic granules often exhibit problems such as localized excessive hardness and uneven color, failing to meet the processing requirements of high-end plastic products. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a plastic granulator with an automatic raw material mixing function.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a plastic granulator with automatic raw material mixing function, comprising a granulator body, a feeding frame connected to the top of the granulator body, an accumulation frame and a processing frame sequentially provided on the top of the feeding frame, four accumulation cavities equally spaced on the inner side of the accumulation frame, a guide frame equally spaced at the bottom of the accumulation frame, and symmetrical support legs on both sides of the accumulation frame;

[0006] The processing frame has an outer frame on its inner side, a filter plate is adhered to the inner side of the outer frame, a guide strip is fixedly connected to the inner side of the processing frame at the top of the outer frame, a connecting plate is fixedly installed on one side of the processing frame, a rotating plate is provided on one side of the connecting plate, and a guide block that penetrates to the inner side of the connecting plate is fixedly installed on one side of the rotating plate.

[0007] Preferably, the guide frame corresponds to the storage chamber, and a valve is connected to the bottom of the guide frame.

[0008] Preferably, the top of the first support leg is provided with a side plate that is fixedly connected to the accumulation frame, and a weighing sensor is installed between the side plate and the first support leg. The bottom of the first support leg is fixedly connected to the main body of the granulator.

[0009] Preferably, the bottom of the outer frame is provided with a discharge frame that communicates with the processing frame, the number of discharge frames matches the number of filter plates, and the inner side of the processing frame is provided with a receiving groove for insertion into the outer frame.

[0010] Preferably, one end of the outer frame extends through to the other side of the processing frame and is fixedly connected to a connecting plate one. One side of the connecting plate one is provided with a connecting plate two that is fixedly connected to the processing frame. The inner sides of the connecting plate one and the connecting plate two are interlocked with insert rods. The inner sides of the connecting plate one and the connecting plate two are each provided with slots, and the insert rods are used in conjunction with the slots for insertion.

[0011] Preferably, the inner side of the connecting plate is provided with a guide groove, the guide block and the guide groove are slidably connected to each other, and a shaft is fixedly installed on the other side of the rotating plate.

[0012] Preferably, two symmetrical side plates are fixedly installed on both sides of the processing frame, and the bottom of the side plate is provided with a support leg fixedly connected to the main body of the granulator. An elastic element is fixedly installed between the support leg and the side plate.

[0013] Preferably, one side of the processing frame is provided with a mounting bracket that is fixedly connected to the second support leg, and a drive motor is fixedly installed on the top of the mounting bracket. The output end of the drive motor is fixedly connected to the shaft through a coupling.

[0014] In summary, this utility model has the following beneficial effects:

[0015] 1. When mixing and proportioning materials in the main body of the granulator, the four accumulation chambers on the accumulation frame can be used to accumulate and accommodate different types of plastic functional additives. When the valve is in the discharge state, the weighing sensor will detect the weight of the accumulation frame in real time, thereby realizing dynamic monitoring of the material discharge in the accumulation frame. Once the weight difference detected by the weighing sensor reaches the mixing requirements, the valve can be closed. This structure can provide the plastic granulator with a step-by-step mixing function for various raw material additives, effectively reducing the transfer feeding link of raw material additives in the existing technology, while avoiding the problem of insufficient feeding accuracy, thus ensuring the quality of plastic particles.

[0016] 2. When the raw material additives in the accumulation chamber are insufficient and need to be replenished, the new raw material additives can be poured onto the corresponding filter plate according to the location of the accumulation chamber. The filter plate will filter the replenished raw material additives, removing large particles that do not meet the standards, thus avoiding problems such as high melting point and uneven melting during subsequent granulation processing. This filtration step is completed directly during the replenishment of raw material additives, without the need for additional operating procedures, effectively simplifying the operation steps.

[0017] 3. When the filter plate needs to be replaced, the operator only needs to remove the insert rod from the slot to release the longitudinal limiting relationship between connecting plate one and connecting plate two. Then pull connecting plate one until the outer frame is completely pulled out of the receiving groove to complete the disassembly of the outer frame and the filter plate. The operation is convenient and efficient.

[0018] 4. During the filtration of additives by the filter plate, the drive motor will drive the shaft and the rotating plate to rotate synchronously, so that the guide block forms a motion trajectory with the shaft as the center. Through the sliding cooperation between the guide block and the guide groove, the connecting plate can be driven to move the processing frame longitudinally back and forth, thereby improving the filtration efficiency of the filter plate for raw materials and additives. This ensures that even when the amount of raw materials and additives replenished is large, the filter plate can still maintain a smooth filtration effect, providing a guarantee for the stable operation of subsequent processing steps.

However, the following embodiments are merely preferred embodiments of this utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described in the implementation plan without creative effort are all within the protection scope of this utility model.

[0039] The specific embodiments of this utility model are described below with reference to the accompanying drawings:

[0040] Example:

[0041] refer to Figures 1-7A plastic granulator with automatic raw material mixing function includes a granulator body 1. The top of the granulator body 1 is connected to a feeding frame 101. The top of the feeding frame 101 is provided with a storage frame 2 and a processing frame 4 in sequence. The inner side of the storage frame 2 is provided with four storage chambers 201 at equal intervals. The bottom of the storage frame 2 is connected with a guide frame 202 at equal intervals. The two sides of the storage frame 2 are provided with mutually symmetrical support legs 3.

[0042] The inner side of the processing frame 4 is provided with an outer frame 5, and a filter plate 501 is adhered to the inner side of the outer frame 5. The top of the outer frame 5 is provided with a guide strip 6 that is fixedly connected to the inner side of the processing frame 4. A connecting plate 802 is fixedly installed on one side of the processing frame 4. A rotating plate 8 is provided on one side of the connecting plate 802. A guide block 801 that penetrates to the inner side of the connecting plate 802 is fixedly installed on one side of the rotating plate 8.

[0043] Specifically, when mixing and proportioning materials in the main body 1 of the granulator, the four accumulation chambers 201 on the accumulation frame 2 can be used to accumulate and accommodate different types of plastic functional additives. When the valve 203 is in the feeding state, the weighing sensor 302 will detect the weight of the accumulation frame 2 in real time, thereby realizing dynamic monitoring of the material feeding situation in the accumulation frame 2. Once the weight difference detected by the weighing sensor 302 reaches the mixing requirements, the valve 203 can be closed. This structure can provide the plastic granulator with a step-by-step mixing function for various raw material additives, effectively reducing the transfer feeding link of raw material additives in the existing technology, while avoiding the problem of insufficient feeding accuracy, thereby ensuring the quality of plastic particles.

[0044] The guide frame 202 corresponds to the accumulation chamber 201. The bottom of the guide frame 202 is connected to the valve 203. The top of the support leg 3 is provided with a side plate 301 that is fixedly connected to the accumulation frame 2. Weighing sensors 302 are installed between the side plate 301 and the support leg 3. The bottom of the support leg 3 is fixedly connected to the granulator body 1.

[0045] Specifically, the guide frame 202 is used to guide the material inside the storage chamber 201 so that the material can be accurately fed into the granulator body 1 when the valve 203 is opened; the support leg 3 supports the storage frame 2 and works with the weighing sensor 302 to detect the weight of the storage frame 2 in real time, thereby realizing dynamic monitoring of the material feeding situation in the storage frame 2.

[0046] The bottom of the outer frame 5 is provided with a discharge frame 401 that communicates with the processing frame 4. The number of discharge frames 401 matches the number of filter plates 501. The inner side of the processing frame 4 is provided with a receiving groove 502 that is used to insert the outer frame 5.

[0047] Specifically, the discharge frame 401 is used to cooperate with the material filtered by the filter plate 501 inside the outer frame 5 to complete the discharge; when the outer frame 5 needs to be replaced and cleaned, the processing frame 4 can be smoothly installed by inserting and fitting the outer frame 5 into the receiving groove 502, ensuring the normal connection of subsequent operations.

[0048] One end of the outer frame 5 extends through to the other side of the processing frame 4 and is fixedly connected to a connecting plate 7. One side of the connecting plate 7 is provided with a connecting plate 701 fixedly connected to the processing frame 4. The inner sides of the connecting plate 7 and the connecting plate 701 are interlocked with a plug rod 702. The inner sides of the connecting plate 7 and the connecting plate 701 are both provided with slots 703. The plug rod 702 is used to insert into the slot 703. The inner side of the connecting plate 802 is provided with a guide groove 803. The guide block 801 and the guide groove 803 are slidably connected to each other. The other side of the rotating plate 8 is fixedly installed with a shaft 901.

[0049] Specifically, when the shaft 901 rotates, it drives the rotating plate 8 to rotate synchronously, so that the guide block 801 forms a motion trajectory with the shaft 901 as the center. Through the sliding cooperation between the guide block 801 and the guide groove 803, the connecting plate 802 is driven to achieve longitudinal reciprocating movement. At the same time, after the outer frame 5 is inserted and installed into the processing frame 4, the connecting plate 7 and the connecting plate 2 702 can be positioned by means of the insertion rod 702, thereby ensuring the installation stability of the outer frame 5 inside the processing frame 4.

[0050] Both sides of the processing frame 4 are fixedly installed with symmetrical side plates 1001. The bottom of the side plate 1001 is provided with a support leg 10 fixedly connected to the granulator body 1. An elastic element 1002 is fixedly installed between the support leg 10 and the side plate 1001. One side of the processing frame 4 is provided with a mounting bracket 11 fixedly connected to the support leg 10. The top of the mounting bracket 11 is fixedly installed with a drive motor 9. The output end of the drive motor 9 is fixedly connected to the shaft 901 through a coupling.

[0051] Specifically, when the drive motor 9 is running, it drives the shaft 901 to rotate. The mounting bracket 11 is used to support and fix the drive motor 9 to ensure its operational stability. During the reciprocating motion of the processing frame 4, the support leg 2 10 and the elastic element 1002 on the side plate 2 1001 can simultaneously achieve the dual functions of flexible connection and support.

[0052] The working principle of this utility model is as follows: When mixing and proportioning materials in the granulator body 1, the four accumulation chambers 201 on the accumulation frame 2 can be used to accumulate and contain different types of plastic functional additives. When it is necessary to process a certain additive by feeding it into the granulator body 1, the corresponding valve 203 can be operated through an external control device. The guide frame 202 is used to guide the material inside the accumulation chamber 201, so that the material can be accurately fed into the granulator body 1 after the valve 203 is opened, thereby realizing the mixing and processing with the raw materials. When the granulator body 1 is in use, the raw materials can be directly fed into the equipment through the external feeding pipe. When the valve 203 is in the feeding state, the weighing sensor 302 will detect the weight of the accumulation frame 2 in real time. When the weight difference detected by the weighing sensor 302 reaches the mixing requirement, the valve 203 can be closed. This structure can provide a gradual mixing function for multiple raw material additives for the plastic granulator.

[0053] When the raw material additive in the accumulation chamber 201 is insufficient and needs to be replenished, the new raw material additive can be poured onto the corresponding filter plate 501 according to the position of the accumulation chamber 201. The filter plate 501 will filter the replenished raw material additive, filtering out large particles that do not meet the standards, so as to avoid problems such as high melting point and uneven melting during subsequent processing and granulation. When the filter plate 501 needs to be replaced, the operator only needs to remove the insertion rod 702 from the slot 703 to release the longitudinal limiting relationship between the connecting plate 1 7 and the connecting plate 2 701. Then, pull the connecting plate 1 7 until the outer frame 5 is completely pulled out of the receiving groove 502, thus completing the disassembly of the outer frame 5 and the filter plate 501.

[0054] During the filtration of additives by filter plate 501, after the drive motor 9 runs, it will drive the shaft 901 to rotate synchronously with the rotating plate 8, so that the guide block 801 forms a motion trajectory with the shaft 901 as the center; through the sliding cooperation between the guide block 801 and the guide groove 803, the connecting plate 802 can be driven to drive the processing frame 4 to achieve longitudinal reciprocating movement, thereby improving the filtration efficiency of filter plate 501 for raw materials and additives.
