Description

Technical Field

[0001] The utility model relates to the field of rubber processing, in particular to a raw material screening device for rubber processing. Background Art

[0002] Rubber is an elastic polymer that can be obtained from the sap of some plants or artificially produced. Rubber is widely used in tires, gaskets, seals, springs and other products, becoming an important economic crop. In addition, rubber can also be used to make rubber and plastic products, inks, pigments, glues, etc.

[0003] China's authorized patent announcement number: CN 213353124 U records "a screening device for rubber processing". Through the brush design on the outer wall of the spiral feeding blade and the outer wall of the scraper, the inner and outer walls of the screen cylinder can be automatically cleaned. Through automatic cleaning, the residue of materials on the inner and outer walls of the screen cylinder can be effectively avoided, and the scaling rate of the inner and outer walls of the screen cylinder can be reduced. At the same time, it can play an auxiliary filtering effect. Through the design of the spiral feeding blade, the traditional gravity screening is changed to flow control screening. Through the control of the material flow rate, the screening time of the material in the screen cylinder can be effectively extended, and then the screening effect can be enhanced. The disturbance of the material by the spiral feeding blade can make the material fully dispersed. At the same time, through the design of the high-pressure nozzle, the impurities adhering to or blocking the screen cylinder can be quickly blown away by the high-pressure airflow.

[0004] However, there are still the following defects and shortcomings in the application process:

[0005] A group of sieve cylinders are arranged as the screening structure, and the sieve cylinders cannot adjust the size of their own leakage holes. Therefore, the accuracy of the rubber raw materials screened by them will be relatively poor. If the size of a batch of rubber particles is smaller than the size of the leakage holes of the screening device, the screening effect will be greatly reduced.

[0006] Therefore, it is necessary to provide a new raw material screening device for rubber processing to solve the above-mentioned technical problems. Utility Model Content

[0031] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0032] The specific implementation of the present utility model is described in detail below in conjunction with specific embodiments.

[0033] See also Figures 1 to 5 , the embodiment of the utility model provides a raw material screening device for rubber processing, the raw material screening device for rubber processing comprises a screening cylinder 1;

[0034] A cavity seat 3 is welded to one end of the screening cylinder 1, and further comprises:

[0035] The adjusting cylinder 2 rotates coaxially outside the screening cylinder 1. One end of the adjusting cylinder 2 is integrally connected to an extension plate 4 extending to the inside of the cavity seat 3. One side of the extension plate 4 is integrally connected to a positioning tooth plate 5. A transmission tooth plate 7 is welded outside the adjusting cylinder 2 and near the other end.

[0036] The locking assembly 6 is arranged on the cavity seat 3 and is engaged and fixed with the positioning tooth plate 5;

[0037] The rotation adjustment component 8 is arranged outside the screening drum 1, and the rotation adjustment component 8 is transmission-connected with the transmission tooth plate 7;

[0038] The rotation of the adjusting drum 2 is used to make the leakage holes on the adjusting drum 2 completely correspond to or stagger with the leakage holes on the screening drum 1 .

[0039] It should be noted that: in the device, a rotatable adjusting cylinder 2 is arranged outside the screening cylinder 1, and the two constitute a complete screening cylinder structure. The leakage holes on the adjusting cylinder 2 can be staggered with the leakage holes on the screening cylinder 1 by rotating, and in the staggered state, the aperture of the leakage holes of the screening cylinder will be reduced to facilitate the adaptation of rubber raw materials with smaller particles, thereby further improving the application range of the device;

[0040] It should also be noted that: the extension plate 4 at the end of the adjustment cylinder 2 extends into the cavity seat 3, and a positioning tooth plate 5 is provided on the extension plate 4, and the locking assembly 6 on the cavity seat 3 can be engaged with the positioning tooth plate 5, so as to elastically fix the extension plate 4. Therefore, when the device is in normal use, the adjustment cylinder 2 has sufficient stability and will not rotate uncontrollably. Moreover, compared with rigid fixation, elastic fixation can better avoid the vibration effect generated when the device is used, and further improve the performance of the device.

[0041] It should also be noted that the rotary adjustment component 8 is in driving connection with the transmission tooth plate 7, so the rotary adjustment component 8 can be directly used to drive the adjustment cylinder 2 to rotate, making it more convenient to adjust the leakage hole diameter of the entire screen cylinder.

[0044] It should be noted that: under normal conditions, the elastic force of the spring 64 can firmly fit the docking tooth plate 62 on the positioning tooth plate 5, thereby fixing the adjustment cylinder 2;

[0045] When adjustment is needed, the handle 66 is directly pulled to drive the positioning plate 61 to move through the connecting rod 65, so that the docking tooth plate 62 is separated from the positioning tooth plate 5. At this time, the adjustment tube 2 is not restricted and can be rotated for adjustment.

[0046] In the embodiments of the present invention, please refer to Figure 1 , Figure 2 and Figure 5 The rotation adjustment assembly 8 includes a mounting plate 81, a rotating shaft 82 is passed through the mounting plate 81, a driving gear 83 coaxially fixed to one end of the rotating shaft 82, a hexagonal block 84 is fixed to the other end, and a nut 85 for fixing is also threadedly connected to the rotating shaft 82;

[0047] The mounting plate 81 is welded to the outside of the screening drum 1 , and the driving gear 83 is meshed with the transmission gear plate 7 .

[0048] It should be noted that the hexagonal block 84 is clamped and fixed by a wrench or other tool to drive the rotating shaft 82 to rotate, thereby driving the driving gear 83 to rotate, and the adjusting cylinder 2 is driven to rotate by the driving gear 83. After the angle is adjusted, the rotating shaft 82 is fixed by the nut 85, and the driving gear 83 can also be used to lock the transmission gear plate 7, which also has a fixing effect on the adjusting cylinder 2.
