[0021] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art may think of other obvious variations.

[0022] Reference Figure 1-5 As shown, a rubber particle drying device for rubber seal production includes a drying box 1, a feed hopper 2 connected and fixed to the top of the drying box 1, and a discharge pipe 3 connected and fixed to the bottom of the drying box 1;

[0023] When in use, the processed rubber particles are added into the inner cavity of the drying box 1 from the feed hopper 2 in advance, so that the rubber particles are fully dried in the inner cavity of the drying box 1. After drying, the rubber particles are discharged through the discharge pipe 3, so as to facilitate the collection of the heated rubber particles.

[0024] Since the rubber products will produce strong toxic gas after heating and drying, when the dried rubber particles are discharged from the discharge pipe 3, the toxic gas will also be discharged from the discharge pipe 3, which will seriously endanger the respiratory health of the operators;

[0025] In view of this, refer to Figure 1 and Figure 2 As shown, it is worth noting that it also includes a suction mechanism for handling toxic gases;

[0026] The suction mechanism includes a ventilator 4 connected and fixed to the side wall of the discharge pipe 3, a drive motor 6 installed inside the ventilator 4 through a bracket, and an impeller 7 tightly sleeved on the output shaft of the drive motor 6. An air filter element 5 is installed in the air outlet end of the ventilator 4.

[0027] By setting the suction mechanism, when the rubber particles are discharged from the discharge pipe 3, the drive motor 6 is turned on, and the output shaft of the drive motor 6 can continuously rotate the impeller 7, thereby continuously forming a suction force on the inner cavity of the discharge pipe 3, so that the toxic gas enters the ventilation tube 4 and is filtered and purified by the air filter element 5, and finally discharged to the outside.

[0028] However, in practice, the suction mechanism will also suck the rubber particles in the discharge pipe 3 while continuing to suck the gas in the discharge pipe 3. In this way, the rubber particles enter the suction device, which will not only endanger the normal use of the impeller 7 and the drive motor 6 as a whole, but also affect the collection of the rubber particles after drying.

[0029] In view of this, refer to Figure 2-5 As shown, it is worth noting that it also includes a blocking mechanism for preventing rubber particles from entering the inner cavity of the discharge pipe 3;

[0030] The material blocking mechanism includes a filter plate 8 fixed in the air suction end of the ventilator 4 and a cleaning component for cleaning the surface of the filter plate 8;

[0031] By setting the intercepting mechanism, in the process of the impeller 7 continuously sucking the toxic gas, the filter plate 8 in the intercepting mechanism can effectively intercept the rubber particles in the sucked gas, and prevent the rubber particles from passing into the ventilation tube 4 and affecting the normal use of the impeller 7. In addition, the cleaning component can still scratch the surface of the filter plate 8 along with the continuous rotation of the output shaft of the driving motor 6, so as to clean the rubber particles attached to its surface and increase the utilization rate of the rubber particles.

[0032] Further, refer to Figure 2-5 As shown, it is worth noting that the cleaning component includes a flip plate 12 vertically arranged below the discharge pipe 3 and wiping plates 13 fixed on both sides of the flip plate 12, a fixed seat 14 with an open end is arranged on the inner wall of one side of the discharge pipe 3, the fixed seat 14 is located below the filter plate 8, a flip assembly is arranged between the open end of the fixed seat 14 and the flip plate 12, and a power assembly is arranged at the other end of the fixed seat 14;

[0033] The power assembly includes a driving rod 9 which is rotatably arranged in the inner side wall of the discharge end of the discharge pipe 3 and a fixing sleeve 10 which is fixedly connected to the fixing seat 14. The fixing sleeve 10 is tightly sleeved on one end of the rod body of the driving rod 9. A belt is connected between the other end of the rod body of the driving rod 9 and the output shaft of the driving motor 6. The belt is inserted into the inner wall of the ventilation tube 4.

[0034] When the drive motor 6 is started and the output shaft of the drive motor 6 drives the impeller 7, the driving rod 9 can rotate synchronously under the action of the belt, causing the fixed sleeve 10, the fixed seat 14 and the flip plate 12 to rotate as a whole, so that the wiping plate 13 on one side of the flip plate 12 intermittently scratches the surface of the filter plate 8, cleans the rubber particles attached to the surface of the filter plate 8, and increases the utilization rate of the rubber particles.

[0035] Further, refer to Figure 3-5 As shown, it is worth noting that the flip assembly includes a transmission rod 11 that is vertically rotatably arranged on the innermost inner wall of the fixing seat 14, and a flip plate 12 is detachably arranged on the rod body of the transmission rod 11 located outside the fixing seat 14. The rod body of the transmission rod 11 located inside the fixing seat 14 is symmetrically provided with two fixing holes, and a locking screw 15 is arranged on one side of the fixing seat 14. The locking screw 15 is threaded into the inner side of the fixing seat 14 and corresponds to one of the fixing holes;

[0036] By setting up the flip assembly, when the wiping plate 13 that has been in long-term contact with the surface of the filter plate 8 is severely worn after long-term use, it is only necessary to simply rotate the flip plate 12 to make the transmission rod 11 rotate inside the fixing seat 14, so that the wiping plates 13 on both sides of the flip plate 12 can be easily replaced. After the replacement of the wiping plate 13 is completed, the locking screw 15 is then screwed so that the locking screw 15 is inserted into the corresponding fixing hole under the threaded structure. In this way, the two cooperate to achieve the fixing effect of the transmission rod 11 and the flip plate 12 as a whole, thereby ensuring the stability of the flip plate 12 after flipping.

[0037] Further, refer to Figure 4 and Figure 5 As shown, it is worth noting that a fixing plate 16 that abuts against one end of the flip plate 12 is tightly sleeved on the rod body of the transmission rod 11, and a nut 17 that abuts against the other end of the flip plate 12 is threadedly connected to the end of the transmission rod 11, and positioning columns 18 are fixed at both ends of the fixing plate 16, and the ends of the positioning columns 18 penetrate the flip plate 12;

[0038] The knob nut 17 allows the nut 17 to exit the shaft of the transmission rod 11 in the threaded structure, thereby releasing the fixation of the flip plate 12. Subsequently, the flip plate 12 only needs to be slid down to allow the flip plate 12 to exit from the transmission rod 11 and the shaft of the positioning column 18, thereby facilitating the removal and replacement of the flip plate 12 and the wiping plate 13 as a whole.

[0039] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and the specification only describe the principles of the utility model.
