Description

Technical Field

[0001] The present invention relates to the technical field of kneading machines, in particular to a preheating spiral device. Background Art

[0002] A 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 in it is fully wetted, so that the batch material has plasticity for preparation and forming. It is usually a machine that requires a preheating spiral to push the material to achieve the conveying purpose. The preheating spiral is used to preheat the material and is widely used in industrial production. Its main functions and roles include: Material preheating: The preheating spiral heats the material to a certain temperature for the smooth progress of subsequent processes. Uniform heating: While the spiral blades of the preheating spiral convey the material, the material is uniformly heated through a heating medium (such as thermal medium oil or thermal resistance), avoiding local overheating or uneven heating of the material.

[0003] Materials of different batches often have different particle sizes and fluidities. According to the different particle sizes and fluidities, the optimal spacing between preheating spirals is also different. If the spacing between preheating spirals is too large, it is easy to cause uneven material distribution, excessive material accumulation in some areas, forming eddies or dead zones, affecting the heat transfer effect, while there is too little material in some areas, thus affecting the uniformity of heating. If the spacing between preheating spirals is too small, it is easy to cause poor material flow and reduce the heat transfer efficiency. The existing preheating spirals have fixed positions and are difficult to adjust according to the particle size and fluidity of the material, which is inconvenient to use and affects the heat transfer efficiency.

Detailed implementation manners

[0030] To make the above objects, features and advantages of the present invention more obvious and understandable, the following will describe the detailed implementation manners of the present invention with reference to the drawings in the specification.

[0031] Example 1, referring to Figures 1-4 , Figure 8 and Figure 9 , this example provides a preheating spiral device, which includes a preheating component 1 and an adjusting component 2. The preheating component 1 includes an upper housing 11, a preheating spiral 12 and a lower housing 13. A preheating spiral 12 is arranged inside the upper housing 11 and the lower housing 13. The preheating spiral 12 is a heat source, and multiple groups of preheating spirals 12 are provided;

[0032] Preferably in this embodiment, a cavity is formed between the upper housing 11 and the lower housing 13 for accommodating materials. Preferably, four groups of preheating spirals 12 are provided for heating the materials. The preheating spiral 12 adopts an existing structure with a hollow interior. The preheating spiral 12 is heated by hot kerosene as a heat source to increase the temperature of the preheating spiral 12, and the preheating spiral 12 is used as a heat source. In one of the embodiments, a feed port is provided on the upper housing 11 for feeding materials.

[0033] The adjusting component 2 includes an adjusting member 21, a first baffle 22 and a second baffle 23. The adjusting member 21 is used to adjust the distance between the preheating spirals 12. The preheating spiral 12 passes through the first baffle 22, and the end of the preheating spiral 12 is rotatably connected to the second baffle 23.

[0034] Referring to Figure 4 , Figure 8 and Figure 9 , adjusting members 21 are respectively provided on the first baffle 22, the second baffle 23 and the first housing 14. The adjusting member 21 includes a movable plate 211, a top plate 212, a slider 213, a second chute 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 chute 214. The bottom of the movable plate 211 is fixedly connected to the bottom plate 215. A limiting groove 216 is formed 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. A through hole 219 is formed on the movable plate 211. The rotating shaft 121 is rotatably connected to the through hole 219.

[0035] Preferably in this embodiment, when the movable rod 218 rises, it can push the limiting shaft 217 to rise. Since the distance between the limiting shafts 217 is fixed, and the limiting groove 216 is inclined as shown in Figure 4 , the limiting shaft 217 slides upward on the inner wall of the limiting groove 216, and at this time, the distance between the bottom plates 215 increases; if the movable rod 218 descends, it drives the limiting shaft 217 to descend. Since the distance between the limiting shafts 217 is fixed, and the limiting groove 216 is as shown in Figure 4Set as shown in the figure to be inclined, the limiting shaft 217 slides downward along the inner wall of the limiting groove 216. At this time, the distance between the bottom plates 215 decreases; the bottom plates 215 drive the movable plate 211 to move. Windows are provided on the first baffle 22 and the second baffle 23, and the movable plate 211 slides inside the windows. The movable plate 211 drives the rotating shaft 121 to move, adjusting the distance between the preheating screws 12. It is possible to adjust the distance between the preheating screws 12 according to the particle size and fluidity of the material, which can prevent the distance between the preheating screws 12 from being too large, resulting in uneven material distribution, excessive material accumulation in some areas, forming vortices or dead zones, affecting the heat transfer effect, too little material in some areas, thus affecting the heating uniformity, and the distance between the preheating screws 12 being too small, which is likely to cause poor material flow and reduce the heat transfer efficiency. At the same time, it is more flexible and convenient to use. Removing the movable plate 211 on the second baffle 23 can take out the material, or an outlet can be provided on the movable plate 211 on the second baffle 23 to take out the material.

[0036] Preferably in this embodiment, the adjusting member 21 is used to adjust the distance between the preheating screws 12. According to the particle size and fluidity of the material, adjusting the distance between the preheating screws 12 can prevent the distance between the preheating screws 12 from being too large, resulting in uneven material distribution, excessive material accumulation in some areas, forming vortices or dead zones, affecting the heat transfer effect, too little material in some areas, thus affecting the heating uniformity, and the distance between the preheating screws 12 being too small, which is likely to cause poor material flow and reduce the heat transfer efficiency. At the same time, it is more flexible and convenient to use.

[0037] Example 2, referring to Figures 1-12 , this embodiment is based on the previous embodiment. The difference from the previous embodiment is that it also includes the following content.

[0038] Referring to Figure 3 , the preheating screw 12 includes a rotating shaft 121, a spiral plate 122 and a driving member 123. The rotating shaft 121 is fixedly connected to the spiral plate 122. The driving member 123 includes a worm gear 1231, a worm 1232 and a first square rod 1233. One end of the rotating shaft 121 is fixedly connected to the worm gear 1231, the worm gear 1231 is meshed with the worm 1232, and the worm 1232 is slidably connected to the first square rod 1233.

[0039] Preferably, in this embodiment, the rotation of the rotating shaft 121 can drive the rotation of the spiral plate 122. In the existing preheating spiral 12 structure, the rotating shaft 121 and the spiral plate 122 are hollow inside, and hot kerosene is used as a heat source to heat the preheating spiral 12 to increase the temperature of the preheating spiral 12, and the preheating spiral 12 is used as a heat source.

The worm 1232 can drive the rotation of the worm wheel 1231. The worm wheel 1231 drives the rotation of the rotating shaft 121. The rotation of the rotating shaft 121 can drive the rotation of the spiral plate 122, that is, drive the rotation of the preheating spiral 12. When the rotating shaft 121 moves, the rotating shaft 121 drives the worm wheel 1231 to move. Under the meshing action of the worm wheel 1231 and the worm 1232, it can drive the worm 1232 to slide on the first square rod 1233 without affecting the rotation of the first square rod 1233 driving the worm 1232.

[0040] Refer to Figure 3 , Figure 5 and Figure 7 , both ends of the first square rod 1233 are respectively rotatably connected to the first housing 14. The first square rod 1233 is fixedly connected to the first transmission wheel 141. The first transmission wheel 141 is connected to the second transmission wheel 143 and the tension wheel 144 through the first belt loop 142.

[0041] Preferably, in this embodiment, the cross-sections of both ends of the first square rod 1233 are circular. Both ends of the first square rod 1233 are rotatably connected to the first housing 14. When the second transmission wheel 143 rotates, it can drive the second transmission wheel 143 and the tension wheel 144 to rotate through the first belt loop 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. The worm wheel 1231 drives the rotation of the rotating shaft 121. The rotation of the rotating shaft 121 can drive the rotation of the spiral plate 122, that is, drive the rotation of the preheating spiral 12.

[0042] Furthermore, in actual operation, a rotating shaft is arranged at the axial center position of the tension wheel 144. Both ends of the rotating shaft are respectively rotatably connected to one end of the support plate. The other end of the support plate is fixedly connected to one end of the existing electric telescopic rod. The other end of the existing electric telescopic rod is fixedly connected to the inner wall of the first housing 14. When the existing electric telescopic rod performs telescopic movement, it can adjust the tightness of the first belt loop 142.

[0043] Refer to Figure 5 and Figure 6The second transmission wheel 143 includes a fixed disk 1431, a movable disk 1432, a first electric telescopic rod 1433 and a fixed ring 1434. The fixed disk 1431 is fixedly connected to the drive shaft 15. The relatively close sides of the fixed disk 1431 and the movable disk 1432 are conical, and the fixed disk 1431 and the movable disk 1432 are located on both sides of the first belt ring 142. The movable disk 1432 is slidably connected to the drive shaft 15. The side of the movable disk 1432 away from the fixed disk 1431 is fixedly connected to one end of the first electric telescopic rod 1433, and the other end of the first electric telescopic rod 1433 is fixedly connected to the fixed ring 1434. The fixed ring 1434 is fixedly connected to the drive shaft 15, and the drive shaft 15 is connected to the motor 17 through the second belt ring 16.

[0044] In this embodiment, preferably, when the driving shaft 15 rotates, it can drive the fixed disk 1431, the movable disk 1432, the first electric telescopic rod 1433 and the fixed ring 1434 to rotate. The movable disk 1432 can slide along the axial direction of the driving shaft 15, and when the first electric telescopic rod 1433 is extended, it can push the movable disk 1432 close to the fixed disk 1431, at which time the first belt ring 142 is squeezed to a position close to the edge of the movable disk 1432 and the fixed disk 1431, and the transmission ratio between the second transmission wheel 143 and the first transmission wheel 141 is increased, which is conducive to increasing the rotation speed of the first transmission wheel 141; when the first electric telescopic rod 1433 is contracted, it can drive the movable disk 1432 away from the fixed disk 1431, and at this time the first belt ring 142 moves to a position close to the axis of the movable disk 1432 and the fixed disk 1431, and the transmission ratio between the second transmission wheel 143 and the first transmission wheel 141 is reduced, which is conducive to driving the high viscosity logistics to rotate, and it is convenient to adjust the transmission ratio.

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.

[0045] Reference Figures 9-11 The lower shell 13 includes a fixed section 131, a movable bar 132, a movable section 133 and an elastic membrane 134. The fixed section 131, the movable bar 132 and the top of the movable section 133 are respectively provided with a first sliding groove 135, and the first sliding groove 135 is slidably connected to the edge of the spiral plate 122, and the fixed section 131, the movable bar 132 and the top of the movable section 133 are connected by the elastic membrane 134.

[0046] Preferably, in this embodiment, the cross-section of the first chute 135 is arc-shaped, facilitating the sliding of the edge of the spiral plate 122. When the movable bar 132 and the movable section 133 move, they drive the elastic membrane 134 to stretch or contract. The elastic membrane 134 always maintains the closure of the lower housing 13 through stretching or contraction, preventing the material from flowing out of the lower housing 13 during the preheating process. The elastic membrane 134 is made of TPU, POE, or polytetrafluoroethylene.

[0047] Referring to Figures 9-11 , the bottom of the fixed section 131 is fixedly connected to the first support leg 1311, the bottom of the movable section 133 is fixedly connected to the second support leg 1331, the second support leg 1331 is fixedly connected to the dovetail slider 136, the dovetail slider 136 is slidably connected to the dovetail chute 137, and the first support leg 1311 and the dovetail chute 137 are respectively fixedly connected to the top of the support frame 138.

[0048] Preferably, in this embodiment, the first support leg 1311 is used to support the fixed section 131, the second support leg 1331 can support the movable section 133, and when the movable section 133 moves, it can drive the dovetail slider 136 to slide on the inner wall of the dovetail chute 137, improving the stability of the movable section 133 when it moves.

[0049] Referring to Figures 9-11 , receiving grooves 1350 are respectively formed at the relatively close bottom sides of the fixed section 131, the movable bar 132, and the movable section 133, and a square groove 1351 is formed on the side wall of the receiving groove 1350.

The second square rod 1352 can slide 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. At the same time, the second square rod 1352 can support the first telescopic rod 1353. When the first telescopic rod 1353 expands and contracts, it can drive the support bar 1354 to rise or fall. When the support bar 1354 rises, it can push up the elastic membrane 134, preventing the material from accumulating at the position of the elastic membrane 134, forming a vortex or a dead zone, and 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, it can squeeze the elastic membrane 134 on the arc surfaces on both sides of the support bar 1354, preventing the support bar 1354 from jamming the spiral plate 122 and preventing the material from accumulating on the elastic membrane 134.

[0052] Preferably in this embodiment, the arc-shaped plate 1361 can slide in the arc-shaped groove 1360. After the arc-shaped plate 1361 extends out of the arc-shaped groove 1360, it can support the elastic membrane 134, preventing materials from accumulating at the position of the elastic membrane 134, forming vortices or dead zones, and affecting the heat transfer effect.

[0053] In one of the embodiments, referring to Figure 9 , the bottoms of the fixed section 131, the movable strip 132, and the movable section 133 are respectively connected to the top of the movable plate 211.

[0054] Referring to Figure 12 , the bottom of the movable rod 218 is fixedly connected to the top of the second telescopic rod 2181. The second telescopic rod 2181 is fixedly connected to one end of the second air inlet pipe 2182. The bottom of the second telescopic rod 2181 is fixedly connected to the support rod 2183. The support rod 2183 is fixedly connected to the support frame 138. The other end of the second air inlet pipe 2182 is fixedly connected to the cylinder 2184. The cylinder 2184 is fixedly connected to one ends of the first air inlet pipe 2185 and the third air inlet pipe 2186. The other end of the first air inlet pipe 2185 is fixedly connected to the first telescopic rod 1353.

The piston head 2187 is fixedly connected to one end of the second electric telescopic rod 2188. The other end of the second electric telescopic rod 2188 is fixedly connected to the inner end wall of the cylinder 2184.

[0055] Preferably in this embodiment, the arc-shaped plate 1361 is shaped like a tile. The arc-shaped plate 1361 can slide in the arc-shaped groove 1360 in the radial direction, and the arc-shaped plate 1361 extends out of or retracts into the arc-shaped groove 1360. When the second electric telescopic rod 2188 extends, it can drive the piston head 2187 to move. The piston head 2187 compresses Figure 11 the air on the left side. At this time, the air enters the first air inlet pipe 2185, the third air inlet pipe 2186, and the arc-shaped groove 1360. The first telescopic rod 1353 connected to the first air inlet pipe 2185 extends. The third air inlet pipe 2186 communicates with the inside of the arc-shaped groove 1360. When the gas enters the arc-shaped groove 1360, the air pressure pushes the arc-shaped plate 1361 to extend, and the second telescopic rod 2181 connected to the second air inlet pipe 2182 extends.

[0056] Cut the cylinder barrel 2184 along the section shown Figure 11 in the figure. After placing the second telescopic rod 2181 and the piston head 2187 into the cylinder barrel 2184, weld the cut cylinder barrel 2184 together to form a complete cylinder barrel 2184.

[0057] Working principle: When it is necessary to increase the spacing of the preheating spiral 12, control the second electric telescopic rod 2188 to extend. The second electric telescopic rod 2188 drives the piston head 2187 to move, and the piston head 2187 compresses Figure 11 the air on the left side. At this time, the air 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, the second telescopic rod 2181 connected to the second air inlet pipe 2182 extends, and the second telescopic rod 2181 extends to push the movable rod 218 upward. When the movable rod 218 rises, it can push the limit shaft 217 upward. Since the spacing between the limit shafts 217 is fixed, and the limit groove 216 is Figure 4 inclined as shown in the figure, the limit shaft 217 slides upward on the inner wall of the limit groove 216. At this time, the spacing between the bottom plates 215 increases, the bottom plates 215 drive the movable plate 211 to move, the movable plate 211 drives the rotating shaft 121 to move, and the spacing of each preheating spiral 12 is increased. Figure 3 In the figure, the spiral plates 122 of each preheating spiral 12 are in the arc of the first chute 135, which can drive the movable strip 132 and the movable section 133 corresponding to the first chute 135 to move, increasing the spacing. The spacing between the movable strip 132 and the movable section 133 increases. The second square rod 1352 slides inside the square groove 1351, and the second square rod 1352 can support the movable strip 132 to prevent the movable strip 132 from falling.

[0058] 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, preventing the material from accumulating at the position of the elastic membrane 134, forming a vortex or a dead zone, and affecting the heat transfer effect. Moreover, the top of the support bar 1354 is triangular, and both sides are concave to form an arc surface. When the spiral plate 122 rotates, it can squeeze the elastic membrane 134 on the arc surfaces on both sides of the support bar 1354, preventing the support bar 1354 from jamming the spiral plate 122 and at the same time preventing the material from accumulating on the elastic membrane 134. The gas in the third air inlet pipe 2186 enters the arc-shaped groove 1360, and the gas pushes the arc-shaped plate 1361 to extend only a part from the arc-shaped groove 1360. The arc-shaped plate 1361 is located on both sides of the support bar 1354. When the spacing of the preheating spiral 12 increases to the maximum, at this time, the first telescopic rod 1353 extends to the maximum length. After the gas in the third air inlet pipe 2186 enters the arc-shaped groove 1360, the gas pushes the arc-shaped plate 1361 to extend the maximum length from the arc-shaped groove 1360, as shown Figure 11At this time, the arc-shaped plate 1361 is located above the support bar 1354, and the support bar 1354 can also support the arc-shaped plate 1361 to prevent the arc-shaped plate 1361 from deforming due to excessive force.

[0059] When it is necessary to reduce the spacing of the preheating spiral 12, the second electric telescopic rod 2188 is controlled to contract, and the second electric telescopic rod 2188 drives the piston head 2187 to move Figure 11 to the right. At this time, 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 communicated with the first air inlet pipe 2185 contracts, and the second telescopic rod 2181 communicated with 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, it drives the limit shaft 217 to descend. Since the spacing between the limit shafts 217 is fixed, and the limit groove 216 is Figure 4 inclined as shown, the limit shaft 217 slides downward along the inner wall of the limit groove 216. At this time, the spacing between the bottom plates 215 decreases, and the movable plate 211 drives the rotating shaft 121 to move, reducing the spacing of each preheating spiral 12. Figure 3 In it, the spiral plates 122 of the preheating spirals 12 can drive the movable bars 132 and the movable sections 133 corresponding to the first sliding groove 135 to move within the arc of the first sliding groove 135 to reduce the spacing. The spacing between the movable bar 132 and the movable section 133 decreases. The second square rod 1352 slides inside the square groove 1351 until the movable bar 132 and the movable section 133 come into contact. The first telescopic rod 1353 contracts, driving the support bar 1354 to descend. At the same time, the gas in the arc-shaped groove 1360 is drawn away, forming a negative pressure. The arc-shaped plate 1361 retracts into the arc-shaped 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 receiving groove 1350.

[0060] It can adjust the spacing of each preheating spiral 12, the movable bar 132, and the movable section 133 according to the particle size and fluidity of the material. Moreover, there is a support bar 1354 or an arc-shaped plate 1361 between the movable bar 132 and the movable section 133 to support the elastic membrane 134, preventing the material from accumulating at the position of the elastic membrane 134, forming a vortex or a dead zone, which affects the heat transfer effect. It can prevent the spacing between the preheating spirals 12 from being too large, resulting in uneven material distribution, excessive material accumulation in some areas, forming a vortex or a dead zone, affecting the heat transfer effect, too little material in some areas, thus affecting the heating uniformity, and the spacing between the preheating spirals 12 being too small, which easily leads to poor material flow and reduces the heat transfer efficiency. At the same time, it is more flexible and convenient to use.

[0061] When the motor 17 works, it can drive the drive shaft 15 to rotate through the second belt loop 16. When the drive 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 tension wheel 144 to rotate through the first belt loop 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 gear 1231 to rotate. The worm gear 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, drive the preheating spiral 12 to rotate, and preheat the material.
