[0031] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments to help understand the content of the present invention. The methods used in the present invention are all conventional methods unless otherwise specified; the raw materials and devices used are all conventional commercial products unless otherwise specified.

[0032] Embodiment 1:

[0033] like Figure 1 As shown, the utility model provides a dust removal system for rubber compounding equipment, including an unpacking hopper 2 and a silo 3 which are interconnected, a conveying assembly for conveying material to a load-bearing device is arranged on one side of the material outlet of the silo 3, a dust collecting hood 103 is arranged above the weighing device 5, the dust collecting hood 103 is connected to the dust removal system, and the dust removal system is connected to the unpacking hopper 2, so that the dust removal system can collect fly ash and smoke generated during the rubber feeding and rubber load-bearing process.

[0034] Existing rubber compounding equipment is usually equipped with a dust removal system to absorb and recycle the dust and debris contained in the rubber, ensure the accuracy of the rubber ratio, reduce the error of the rubber content, and thus provide guarantee for the quality of the produced rubber products;

[0035] However, the existing dust removal system has the following problems: the unpacking hopper 2 and the silo 3 are respectively arranged between different floors, and the dust removal system is arranged on the side of the feeding port close to the unpacking hopper 2 in order to remove the dust carried in the rubber material as soon as possible. The above arrangement can realize the dust removal operation as soon as possible, but some dust will still fall into the weighing device 5;

[0036] At present, in the process of proportioning the rubber material, the weight error value of each material of the rubber material needs to be set at about 0.02 kg, resulting in that after a period of feeding operation, the dust falling in the silo 3 will still have a great impact on the proportion of the rubber material.

[0037] Therefore, the inventors of this application set the partition plate 104 in the dust collector 1, such as Figure 5 , Figure 6 As shown, the chamber of the dust collector 1 is divided into an unpacking dust removal chamber 101 and a weighing dust removal chamber 102, and the unpacking dust removal chamber 101 and the weighing dust removal chamber 102 are respectively connected to the unpacking bucket 2 and the dust collecting hood 103, so as to realize multiple dust removal operations in the process of putting the rubber material into the unpacking bucket 2 and in the process of putting the rubber material into the weighing device 5, so as to minimize the influence of dust on the rubber material ratio.

[0038] In the existing rubber batching device, the unpacking hopper 2 and the silo 3 are connected to each other. Although the continuous operation of the dust removal system can continuously absorb the dust in the unpacking hopper 2 and the silo 3 under normal conditions, when the staff opens the unpacking hopper 2 to put in the rubber, the dust removal system cannot continuously absorb the dust in the silo 3 because the feeding port of the unpacking hopper 2 is open, resulting in the dust removal system The dust absorption effect of the dust removal system on the silo 3 is not obvious. After a period of rubber feeding operation, the rubber in the silo 3 still contains a lot of dust and impurities;

[0039] However, by improving the structure of the dust collector 1 and dividing the dust collector 1 into an unpacking dust removal chamber 101 and a weighing dust removal chamber 102, while ensuring the continuous operation of the dust collector 1, it can be effectively ensured that the dust collector 1 fully recovers the dust and impurities in the unpacking process and the rubber conveying process, thereby ensuring the accuracy of the rubber raw material ratio, and further achieving the improvement of the product performance of the rubber product to meet the production needs.

[0040] Further, such as Figure 4 As shown, the unpacking dust removal chamber 101 and the weighing dust removal chamber 102 are both provided with a plurality of bag filters 107, and a pulse system 106 is correspondingly provided above the bag filters 107 in the dust collector 1, and the bag filters 107 are cleaned by the pulse system 106 to ensure the filtering effect of the dust collector 1;

[0041] Since the existing pulse system 106 may cause the installation structure of the bag filter 1 to loosen during the cleaning operation of the bag filter 107, or even cause the bag filter 1 to fall, the inventors have provided the movable baffle 105 at the lower end of the weighing dust removal chamber 102. Figure 5 As shown, the movable baffle 105 is flipped in the dust collector 1 to realize the switch state of the weighing dust removal chamber 102. When the staff finds that the bag filter 107 in the weighing dust removal chamber 102 has fallen, the baffle 105 can be opened to quickly install the fallen bag dust collector 1, thereby reducing the long downtime of the dust collector 1 due to fault problems, thereby ensuring that the dust removal effect of the dust collector 1 on the rubber material remains stable;

[0042] Since the unpacking and dust removal chamber 101 is directly connected to the unpacking hopper 2 and the silo 3, in order to prevent the bag filter 107 in the unpacking and dust removal chamber 101 from falling directly into the silo 3, as shown in FIG. Figure 2 As shown, the filter 201 is arranged near the delivery port in the unpacking bucket 2. The filter 201 can cover the delivery port of the unpacking bucket 2 and the connecting portion between the unpacking bucket 2 and the unpacking dust removal chamber 101, so that the filter 201 can be used for preliminary filtering of the rubber material and can also prevent the bag filter 107 in the unpacking dust removal chamber from falling onto the filter 201, and the bag filter 107 directly falls into the silo 3.

[0043] Furthermore, the filter 201 near the inlet of the unpacking bucket 2 can be a magnetic filter 201 to filter the metal impurities contained in the rubber material to avoid the situation where the metal impurities are too heavy to be recovered by the dust collector 1.

[0044] like Figure 3 , Figure 7As shown, a discharge port is provided at the lower end of the silo 3, and a conveying assembly 4 for conveying the rubber material to the weighing device 5 is provided on one side of the discharge port. The conveying assembly 4 includes two horizontally placed spiral blade shafts 401, and the orderly conveying of the rubber material can be achieved through the rotation operation of the spiral blade shafts 401. A feeding port is provided at the lower end position of the conveying assembly 4 along the conveying direction of the spiral blade shafts 401, and the feeding port of the conveying assembly 4 passes through the dust collecting cover 103 and is arranged toward the weighing device 5;

[0045] Furthermore, in order to achieve accurate delivery of the rubber material, the diameters of the two spiral blade shafts 401 are designed to be different from each other, and the two spiral blade shafts 401 are respectively connected to two independent drive units, and the two drive units and the weighing device 5 are respectively connected to the controller. When the controller receives a weighing signal from the weighing device 5 close to a preset weight value, the controller controls the drive unit connected to the spiral blade shaft 401 with a larger diameter to stop running, and continues to drive the drive unit connected to the spiral blade shaft 401 with a smaller diameter. When the weighing signal of the weighing device 5 is consistent with the preset weight value in the controller, the controller controls the drive unit to stop the two spiral blade shafts 401 respectively, thereby achieving symmetrical weight taking to achieve a more precise control purpose.

[0046] When the conveying component 4 is dropping the rubber material onto the weighing device 5, in order to prevent the conveying component 4 from being too far away from the weighing tray 501 of the weighing device 5, which would cause the rubber material to have a large change in the weighing weight during the falling process, and the controller would be unable to accurately judge the weighing weight of the weighing device 5, causing the controller to trigger the weighing weight to be excessive, and then send out an alarm signal to stop the operation of the rubber material conveying line, the inventors set the lifting component 502 on the weighing tray 501, and the lifting movement of the lifting component 502 would cause the weighing tray 501 to move upward. 501 can be close to the delivery port of the conveying component 4. At the same time, in order to avoid contact between the weighing tray 501 and the dust collecting hood 103, which will affect the weighing weight of the weighing device 5, the lifting height of the lifting component 502 is set to make the rising height of the weighing tray 501 as close to the delivery port of the conveying component 4 as possible, while avoiding contact between the weighing tray 501 and the dust collecting hood 103. The above setting method can further improve the accuracy of the weighing weight of the weighing device 5, thereby providing an accurate judgment basis for the controller.

[0047] Furthermore, the rotational spacing distance between the spiral blades on the spiral blade shaft 401 gradually increases along the rubber conveying direction to slow down the rubber conveying speed of the conveying component 4, so as to achieve a better control effect on the transmission weight of the rubber.

[0049] However, what is described above is only a specific embodiment of the present invention and should not be used to limit the scope of implementation of the present invention. Therefore, the replacement of equivalent components, or equivalent changes and modifications made according to the scope of protection of the patent of the present invention should still fall within the scope covered by the claims of the present invention.
