[0002] The kneading machine is used to heat the batch material to a temperature slightly higher than the softening point of the binder, and through kneading, the binder is fully moistened to make the batch material plastic in order to prepare the molding. Usually a preheating screw is required to push the material to achieve the purpose of conveying. The preheating screw is used to preheat the material and is widely used in industrial production. Its main functions and effects include: Material preheating: The preheating screw heats the material to a certain temperature so that the subsequent process can proceed smoothly. Uniform heating: While conveying the material, the spiral blades of the preheating screw uniformly heat the material through the heating medium (such as heat medium oil or thermal resistor) to avoid local overheating or uneven heating of the material.

DETAILED DESCRIPTION

[0028] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0029] Example 1, reference Figure 1-Figure 4 , Figure 8 and Fig. 9 This embodiment provides a preheating spiral device, including a preheating component 1 and an adjusting component 2. The preheating component 1 includes an upper shell 11, a preheating spiral 12 and a lower shell 13. The upper shell 11 and the lower shell 13 are provided with a preheating spiral 12 inside. The preheating spiral 12 is a heat source, and the preheating spiral 12 is provided with multiple groups; In this embodiment, preferably, a cavity is formed between the upper shell 11 and the lower shell 13 for accommodating materials, and preferably four groups of preheating spirals 12 are provided for heating materials. The preheating spirals 12 adopt an existing structure, are hollow inside, and are heated by hot kerosene as a heat source to increase the temperature of the preheating spirals 12, and the preheating spirals 12 are used as a heat source. In one embodiment, a feed port is provided on the upper shell 11 for feeding materials.

[0030] The adjusting assembly 2 comprises an adjusting member 21 , a first baffle 22 and a second baffle 23 . The adjusting member 21 is used to adjust the spacing between the preheating spirals 12 . The preheating spirals 12 pass through the first baffle 22 , and the ends of the preheating spirals 12 are rotatably connected to the second baffle 23 .

[0031] Reference Figure 4 , Figure 8 and Fig. 9 The first baffle plate 22, the second baffle plate 23 and the first shell 14 are respectively provided with adjusting members 21, and the adjusting members 21 include a movable plate 211, a top plate 212, a slider 213, a second slide groove 214, a bottom plate 215, a limiting groove 216, a limiting shaft 217, a movable rod 218 and a through hole 219. The top of the movable plate 211 is fixedly connected to the bottom of the top plate 212, the top of the top plate 212 is fixedly connected to the slider 213, the slider 213 is slidably connected to the inner wall of the second slide groove 214, the bottom of the movable plate 211 is fixedly connected to the bottom plate 215, a limiting groove 216 is provided on the bottom plate 215, the inner wall of the limiting groove 216 is slidably connected to the limiting shaft 217, the limiting shaft 217 is fixedly connected to the movable rod 218, and a through hole 219 is provided on the movable plate 211, and the rotating shaft 121 is rotatably connected to the through hole 219.

[0032] In this embodiment, the movable rod 218 is preferably able to push the limit shaft 217 to rise when it rises. Since the spacing between the limit shafts 217 is fixed, and the limit groove 216 is Figure 4 As shown in the inclined arrangement, the limit shaft 217 slides upward on the inner wall of the limit groove 216, and the distance between each base plate 215 increases; if the movable rod 218 is lowered, the limit shaft 217 is driven to fall, because the distance between the limit shafts 217 is fixed, and the limit groove 216 is as shown in the inclined arrangement. Figure 4The bottom plate 215 is tilted, and the limit shaft 217 slides downward on the inner wall of the limit groove 216. At this time, the spacing between the bottom plates 215 is reduced; the bottom plate 215 drives the movable plate 211 to move, and the first baffle 22 and the second baffle 23 are provided with windows, and the movable plate 211 slides inside the window. The movable plate 211 drives the rotating shaft 121 to move, and the spacing between the preheating spirals 12 can be adjusted according to the particle size and fluidity of the material. The spacing between the preheating spirals 12 can be prevented from being too large, resulting in uneven material distribution, too much material accumulation in some areas, forming eddy currents or dead zones, affecting the heat transfer effect, too little material in some areas, thereby affecting the uniformity of heating, and too small spacing between the preheating spirals 12, which easily leads to poor material flow and reduced heat transfer efficiency. At the same time, it is more flexible and convenient to use. The movable plate 211 on the second baffle 23 can be removed to take out the material, or a discharge port can be set on the movable plate 211 on the second baffle 23 to take out the material.

[0033] Preferably, in this embodiment, the adjusting member 21 is used to adjust the spacing between the preheating spirals 12. The spacing between the preheating spirals 12 is adjusted according to the particle size and fluidity of the material. This can prevent the spacing between the preheating spirals 12 from being too large, resulting in uneven material distribution, excessive accumulation of material in some areas, forming eddy currents or dead zones, affecting the heat transfer effect, too little material in some areas, thereby affecting the uniformity of heating, and too small spacing between the preheating spirals 12, which can easily lead to poor material flow and reduce heat transfer efficiency. At the same time, it is more flexible and convenient to use.

Fig.11 The air on the left side now enters the first air inlet pipe 2185, the third air inlet pipe 2186 and the arc groove 1360, the first telescopic rod 1353 connected to the first air inlet pipe 2185 is extended, and the third air inlet pipe 2186 is connected to the inside of the arc groove 1360. When the gas enters the arc groove 1360, the air pressure pushes the arc plate 1361 to extend, and the second telescopic rod 2181 connected to the second air inlet pipe 2182 is extended.

[0053] The cylinder 2184 is along Fig.11 After the cross section shown in FIG. 2 is cut open, the second telescopic rod 2181 and the piston head 2187 are placed into the cylinder barrel 2184 , and then the cut cylinder barrel 2184 is welded together to form a complete cylinder barrel 2184 .

[0054] Working principle: When the spacing of the preheating spiral 12 needs to be increased, the second electric telescopic rod 2188 is controlled to extend, and the second electric telescopic rod 2188 drives the piston head 2187 to move, and the piston head 2187 is compressed. Fig.11 The air on the left side enters the first air inlet pipe 2185, the second air inlet pipe 2182 and the third air inlet pipe 2186. The first telescopic rod 1353 connected to the first air inlet pipe 2185 extends, and the second telescopic rod 2181 connected to the second air inlet pipe 2182 extends. The extension of the second telescopic rod 2181 pushes the movable rod 218 to rise. When the movable rod 218 rises, it can push the limit shaft 217 to rise. Since the spacing between the limit shafts 217 is fixed, and the limit groove 216 is as shown in FIG. Figure 4 As shown in the inclined arrangement, the limiting shaft 217 slides upward on the inner wall of the limiting groove 216, at this time, the distance between each bottom plate 215 increases, the bottom plate 215 drives the movable plate 211 to move, and the movable plate 211 drives the rotating shaft 121 to move, thereby increasing the distance between each preheating spiral 12. Figure 3 In the figure, the spiral plate 122 of each preheating spiral 12 is in the arc of the first slide groove 135, which can drive the movable bar 132 and the movable segment 133 corresponding to the first slide groove 135 to move, increase the spacing, and the spacing between the movable bar 132 and the movable segment 133 increases. The second square rod 1352 slides inside the square groove 1351, and the second square rod 1352 can support the movable bar 132 to prevent the movable bar 132 from falling.

[0055] At the same time, the first telescopic rod 1353 extends to push the support bar 1354 upward, which can push up the elastic membrane 134 and prevent materials from accumulating at the elastic membrane 134 to form vortexes or dead zones, thereby affecting the heat transfer effect. Moreover, the top of the support bar 1354 is triangular, and the two sides are concave to form arc surfaces. When the spiral plate 122 rotates, the elastic membrane 134 can be squeezed on the arc surfaces on both sides of the support bar 1354 to prevent the support bar 1354 from getting stuck on the spiral plate 122 and prevent materials from accumulating on the elastic membrane 134. After the gas in the third air inlet pipe 2186 enters the arc groove 1360, the gas pushes the arc plate 1361 to only extend a portion of the arc groove 1360, and the arc plate 1361 is located on both sides of the support bar 1354. When the spacing of the preheating spiral 12 increases to the maximum, the first telescopic rod 1353 is extended to the maximum length, and after the gas in the third air inlet pipe 2186 enters the arc groove 1360, the gas pushes the arc plate 1361 to extend from the arc groove 1360 to the maximum length. Fig.11In the middle position, the arc plate 1361 is located above the support bar 1354, and the support bar 1354 can also support the arc plate 1361 to prevent the arc plate 1361 from being deformed due to excessive force.

[0056] When the spacing of the preheating spiral 12 needs to be reduced, the second electric telescopic rod 2188 is controlled to retract, and the second electric telescopic rod 2188 drives the piston head 2187 to move Fig.11 The air is drawn out from the first air inlet pipe 2185, the second air inlet pipe 2182 and the third air inlet pipe 2186. The first telescopic rod 1353 connected to the first air inlet pipe 2185 contracts, and the second telescopic rod 2181 connected to the second air inlet pipe 2182 contracts. The second telescopic rod 2181 drives the movable rod 218 to descend. When the movable rod 218 descends, the limit shaft 217 is driven to descend. Since the spacing between the limit shafts 217 is fixed, and the limit grooves 216 are as shown in FIG. Figure 4 As shown in the inclined arrangement, the limiting shaft 217 slides downward on the inner wall of the limiting groove 216, at this time, the distance between each bottom plate 215 is reduced, and the movable plate 211 drives the rotating shaft 121 to move, thereby reducing the distance between each preheating spiral 12. Figure 3 In the embodiment, the spiral plate 122 of each preheating spiral 12 is in the arc of the first slide groove 135, which can drive the movable bar 132 and the movable segment 133 corresponding to the first slide groove 135 to move, reduce the spacing, and reduce the spacing between the movable bar 132 and the movable segment 133. The second square rod 1352 slides inside the square groove 1351 until the movable bar 132 and the movable segment 133 are in contact, and the first telescopic rod 1353 contracts, driving the support bar 1354 to descend. At the same time, the gas in the arc groove 1360 is drawn away to form a negative pressure. The arc plate 1361 retracts into the arc groove 1360 under the action of the negative pressure. At this time, the first telescopic rod 1353 and the support bar 1354 are located inside the accommodating groove 1350.

[0057] The spacing between each preheating spiral 12, movable bar 132 and movable segment 133 can be adjusted according to the particle size and fluidity of the material. A support bar 1354 or an arc plate 1361 is provided between the movable bar 132 and the movable segment 133 to support the elastic membrane 134, so as to prevent the material from accumulating at the position of the elastic membrane 134 to form eddy currents or dead zones, thereby affecting the heat transfer effect. The system can prevent the spacing between the preheating spirals 12 from being too large, thereby causing uneven material distribution, excessive accumulation of material in some areas to form eddy currents or dead zones, thereby affecting the heat transfer effect, and too little material in some areas to affect the uniformity of heating. The spacing between the preheating spirals 12 is too small, thereby easily causing poor material flow and reducing the heat transfer efficiency. At the same time, the system is more flexible and convenient to use.

[0058] When the motor 17 is working, it can drive the driving shaft 15 to rotate through the second belt ring 16. When the driving shaft 15 rotates, it can drive the second transmission wheel 143 to rotate. When the second transmission wheel 143 rotates, it can drive the second transmission wheel 143 and the tensioning wheel 144 to rotate through the first belt ring 142. When the second transmission wheel 143 drives the first square rod 1233 to rotate, the first square rod 1233 can drive the worm 1232 to rotate, the worm 1232 can drive the worm wheel 1231 to rotate, and the worm wheel 1231 drives the rotating shaft 121 to rotate. The rotation of the rotating shaft 121 can drive the spiral plate 122 to rotate, that is, it drives the preheating spiral 12 to rotate, so as to preheat the material.
