[0031] The preferred embodiment of the present invention will be further described with reference to the accompanying drawings. Figures 1 to 3As shown, the automatic solid-state colloid mixer includes a rubber mixing device 10 and a rubber filtering device 20. The rubber mixing device 10 includes a rubber mixing chamber 100, in which a stirring shaft 110 and a conveying shaft 120 are horizontally arranged. One end of the stirring shaft 110 and the conveying shaft 120 pass through the rubber mixing chamber 100 and are connected to a stirring device 200 and a first conveying device 300 respectively. When the colloid to be melted is placed in the rubber mixing chamber 100, the stirring device 200 is used to drive the stirring shaft 110 to rotate, so that the colloid can be fully arranged in the rubber mixing chamber 100 for stirring. A first rubber outlet 130 is also provided on the rubber mixing chamber 100. The first conveying device 300 is used to drive the conveying shaft 120 to rotate, so that the colloid is conveyed out of the rubber mixing chamber 100 from the first rubber outlet 130. The rubber filtering device 20 includes a rubber filtering chamber 21, the conveying shaft 120 is also arranged in the rubber filtering chamber 21, a second rubber outlet 22 is arranged on the side wall of the rubber filtering chamber 21, a filter screen 23 is arranged in the second rubber outlet 22, and a rotating motor 24 is arranged outside the rubber filtering chamber 21. The rotating motor 24 is used to drive the conveying shaft 120 to rotate, so that the colloid is transferred from the second rubber outlet 22 to the outside of the second rubber outlet 22. A rubber inlet 25 is provided at the top of the rubber filtering chamber 21, and an electric conveyor belt 30 is provided between the rubber inlet 25 and the first rubber outlet 130. A cutting device 400 is provided outside the first rubber outlet 130 and the second rubber outlet 22. The cutting device 400 is used to cut the colloid that has been melted and filtered according to a preset interval.

[0032] When the above embodiment is working, the colloid is first placed in the rubber mixer, and then the stirring device 200 and the first conveying device 300 are started to drive the stirring shaft 110 and the conveying shaft 120 to rotate. After stirring, the colloid is moved out of the rubber mixing chamber 100 through the rubber port by the conveying shaft 120. When the colloid moves out of the rubber mixing chamber 100, the cutting device 400 is started to cut the melted colloid according to a preset interval, and then the cut colloid enters the rubber filtering chamber 21 from the rubber inlet 25 through the electric conveyor 30, and then the rotating motor 24 is started. The colloid is moved out of the rubber filtering chamber 21 after passing through the second rubber outlet 22 and the filter screen 23 by the conveying shaft 120, and then the cutting device 400 is started to cut the filtered colloid according to a preset interval.

[0033] Compared with the prior art, the present application cuts the colloid which has completed melting and filtering through the cutting device 400 according to a preset interval, so that the colloid is cut into several parts, thereby facilitating subsequent placement of the colloid in the rubber filtering equipment and subsequent further processing after the colloid filtering is completed. In addition, the rubber mixing device 10 and the rubber filtering device 20 are connected through the electric conveying belt 30, and the high-temperature colloid can be directly conveyed through the electric conveying belt 30 without manual intervention, which greatly improves the production efficiency and protects the workers from high temperature and injury.

[0034] Further to the above embodiments, as shown in Figure 4 The cutting device 400 includes a conveying platform 410 arranged outside the first rubber outlet 130, a lifting cylinder 420 arranged above the conveying platform 410, a connecting plate 430 arranged at the bottom of the lifting cylinder 420, the lifting cylinder 420 can drive the connecting plate 430 to move up and down, connecting rods 440 arranged on both sides of the connecting plate 430, and a cutter 450 arranged between the connecting rods 440. When the colloid is moved from the first rubber outlet 130 to the conveying platform 410 and the colloid on the conveying platform 410 meets the preset interval, the lifting cylinder 420 is started to drive the connecting plate 430 to descend, thereby driving the connecting rods 440 and the cutter 450 to cut the colloid on the conveying platform 410.

[0035] In some embodiments, as shown in Figure 4 The sensor 460 is electrically connected to the lifting cylinder 420, and when the colloid moves on the conveying platform 410 and triggers the sensor 460, an electrical signal is sent to the lifting cylinder 420 to start the lifting cylinder 420 to drive the connecting plate 430 to descend, thereby driving the connecting rods 440 and the cutter 450 to cut the colloid on the conveying platform 410.

[0036] Further to the above embodiments, as shown in Figure 5 The side wall and the bottom of the rubber mixing cavity 100 are in a U shape, so that the colloid placed in the rubber mixing cavity 100 can better enter the bottom of the rubber mixing cavity 100. The rubber outlet passage 140 is arranged at the bottom of the rubber mixing cavity 100, the conveying shaft 120 is arranged in the rubber outlet passage 140, and the first rubber outlet 130 is arranged at one end of the rubber outlet passage 140. Therefore, when the colloid is placed in the rubber mixing cavity 100, it can first fall into the rubber outlet passage 140, and then the first conveying device 300 is started to drive the conveying shaft 120 to rotate, so as to send the stirred colloid to the first rubber outlet 130. In this process, the rubber outlet passage 140 can better guide the movement of the colloid.

[0037] In some embodiments, asFigure 5 As shown in the figure, the number of the stirring shafts 110 is two and they are placed side by side above the conveying shaft 120, so when the rubber mass is put into the mixing chamber 100, the stirring device 200 is started to drive the stirring shafts 110 to rotate, so that the rubber mass can be fully stirred before reaching the conveying shaft 120.

[0038] Further based on the above embodiment, as shown in the figure, Figure 6 As shown in the figure, the stirring device 200 includes a stirring motor 210 and a main shaft 220, the stirring motor 210 drives the main shaft 220 to rotate, a secondary shaft 230 is arranged on one side of the main shaft 220 and engaged with the main shaft 220, when the main shaft 220 rotates, it can drive the secondary shaft 230 to rotate synchronously, the main shaft 220 and the secondary shaft 230 are connected with the stirring shafts 110 respectively, so that when the stirring motor 210 is started, the two stirring shafts 110 can be driven to rotate simultaneously.

[0039] Further based on the above embodiment, as shown in the figure, Figure 6 As shown in the figure, the first conveying device 300 includes a first conveying motor 310 and a first gear shaft 320, the first conveying motor 310 can drive the first gear shaft 320 to rotate, a second gear shaft 330 is arranged on one end of the conveying shaft 120, the first gear shaft 320 and the second gear shaft 330 are engaged with each other through a chain (not shown in the figure), so that when the first conveying motor 310 is started, the conveying shaft 120 can be driven to rotate through the second gear shaft 330.

[0040] Further based on the above embodiment, as shown in the figure, Figure 7 As shown in the figure, an extension part 150 is arranged on one side of the mixing chamber 100, the stirring shafts 110 pass through the outer wall of the mixing chamber 100 and are connected with the extension part 150, so that the stirring shafts 110 have three supporting points in the mixing chamber 100, namely the two outer walls of the mixing chamber 100 and the extension part 150, so that when there is a large amount of rubber mass in the mixing chamber 100, the stirring shafts 110 have enough supporting points, thereby reducing the risk of breaking during stirring.

[0041] The details of the above exemplary embodiments, and in the absence of departing from the spirit or basic characteristics of the present application, the present application can be realized in other specific forms. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting, the scope of the present application is defined by the appended claims rather than the above description, therefore all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the present application.
