DETAILED DESCRIPTION

[0027] In order to make the purpose, technical solutions and advantages of the present invention more clear, the present invention is further described in detail below with reference to the accompanying drawings and embodiments.

[0028] Example 1

[0029] In this embodiment, if Figure 1-Figure 7As shown, the mixing equipment for rubber processing includes a box body 101, which is a common mixing equipment structure in this field.

The upper end of the box body 101 is fixedly connected to a pressurizing box 103, and a pressing plate 104 is slidably provided inside the pressurizing box 103. The pressing plate 104 is used to enter the pressurizing box 103 to seal the top of the box body 101, thereby ensuring the processing effect of the rubber in the box body 101, so that the box body 101 is in a sealed state. The upper end of the pressing plate 104 is fixedly connected to the output end of the electric push rod 105, and the electric push rod 105 drives the pressing plate 104 to push the rubber raw material into the mixing chamber 4, further pressurizing the mixed material in the box body 101 and improving the mixing effect. The electric push rod 105 is fixedly connected to the U-shaped frame 106, and the box body 101 is arranged inside the U-shaped frame 106 to support the electric push rod 105.

[0030] The box 101 further includes an adjusting mechanism 200 and a feeding mechanism 300. The adjusting mechanism 200 is provided on both sides of the rotor 102 for adjusting the internal space of the box 101. The feeding mechanism 300 is provided at the upper end of the U-shaped frame 106 for feeding the rubber into the box 101.

[0031] The adjusting mechanism 200 includes symmetrically arranged threaded sleeves 201, which are rotatably connected to the outer surface of the box body 101. A gear assembly for driving the threaded sleeve 201 to rotate is provided on one side of the threaded sleeve 201. The internal thread of the threaded sleeve 201 is provided with a threaded rod 202. The threaded sleeve 201 rotates and drives the threaded rod 202 to transmit, so that the threaded rod 202 can move along the direction of the threaded sleeve 201, thereby realizing the movement operation of the slide 203. One end of the threaded rod 202 extends to the inside of the box body 101 and is in contact with the outer surface of the box body 101. The slide 203 is rotatably connected, and the inner diameter of the pressurizing box 103 is smaller than the shortest distance between the two slides 203, so as to avoid some rubber material accumulating on the upper surface of the slide 203 during unloading. The slide 203 is slidably connected to the inner wall of the box body 101, and the two slides 203 move synchronously, which is convenient for adjusting the internal space of the box body 101 according to the amount of rubber material, thereby improving the mixing efficiency and quality, and enabling the rotor 102 to quickly roll up the rubber material for mixing in the optimal internal space of the box body 101, thereby reducing processing time and improving work efficiency.

[0032] Among them Figure 3 and Figure 4As shown, the gear assembly includes a first gear 204 fixedly arranged on the outer surface of the threaded sleeve 201, the first gear 204 is rotatably connected to the box body 101, and a second gear 205 is meshedly arranged on one side of the first gear 204, the second gear 205 is rotatably connected to the outer wall of the box body 101, and one end of the rotating shaft of the second gear 205 is fixedly connected to the output end of the first motor. When the first motor is started, the second gear 205 rotates, driving the first gear 204 and the threaded sleeve 201 to rotate, thereby realizing the position adjustment operation of the threaded rod 202. The first motor is fixedly connected to the box body 101 through a bracket, and the first motor is supported by the bracket.

[0033] Among them Figure 2 and Figure 7 As shown, the feeding mechanism 300 includes a mixing box 301, a feeding port 302 is provided on the top of the mixing box 301, and a cover plate 303 is hinged on the top of the feeding port 302 to seal the material inside the mixing box 301 to prevent impurities from entering. A stirring roller is rotatably provided inside the mixing box 301, and a stirring blade 304 is fixedly provided on the outside of the stirring roller to prevent the rubber material from being blocked at the upper end of the mixing box 301 after being discharged, resulting in poor discharge and affected mixing speed. One end of the stirring roller extends to the outside of the mixing box 301 and is fixedly connected to the output end of the second motor. The mixing box 301 is connected to the box body 101 through a feeding pipe 305, and a valve body is provided on the feeding pipe 305 to introduce the material inside the mixing box 301 into the feeding pipe 305, so as to facilitate the introduction into the box body 101 for mixing.

[0034] Among them Figure 2 As shown, a door 107 is hinged on the lower surface of the box body 101 to facilitate taking out the materials inside the box body 101.

[0035] Among them Figure 1 and Figure 5 As shown, a slide groove 108 is provided on the upper surface of the bottom plate of the U-shaped frame 106, and a screw 109 is rotatably set inside the slide groove 108.

One end of the screw 109 extends to the outside of the U-shaped frame 106 and is fixedly connected to the handle. The user can drive the screw 109 to rotate by turning the handle to achieve the movement effect of the blanking frame 110, and push the blanking frame 110 to the lower part of the box door 107. After unloading, the blanking frame 110 is moved again to take out the rubber material for convenient storage.

[0036] Among them Figure 1-Figure 3 As shown, support members 111 are symmetrically provided on both sides of the box body 101 to play a supporting role and facilitate movement.

[0037] Example 2

The arc-shaped plates 206 are provided on opposite sides of the two slides 203 to facilitate the rotor 102 to roll up the rubber material more easily.

[0039] Among them Figure 5 and Figure 7 As shown, guide rods 207 are fixedly provided on the opposite sides of the two slides 203, and openings matching the guide rods 207 are opened on the surface of the box body 101 to guide the slides 203 and increase the safety and stability of the device.

When it is necessary to adjust the internal space of the box body 101, the second motor drives the second gear 205 to rotate, and then drives the first gear 204 and the threaded sleeve 201 to rotate, thereby realizing the position adjustment operation of the threaded rod 202 and the slide plate 203. The two slide plates 203 are close to or away from each other, realizing the adjustment operation of the internal space of the box body 101, which is convenient for adapting to rubber materials of different contents and improving the mixing efficiency.

Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in this application should be included in the scope of protection of the present application. Therefore, the scope of protection of the present application should be based on the scope of protection of the claims.
