[0002] With the widespread use of plastics and rubber products in people's lives and production, waste plastics and waste rubber products have also increased year by year. For a long time, due to the lack of effective treatment, they have polluted the environment and occupied a large amount of space. The useful components in them have not been effectively utilized, resulting in a large waste of resources.

[0003] Since the waste plastic mixture has a certain degree of adhesion at high temperature, on the one hand, the traditional solid spiral blades encounter greater resistance during transportation, and on the other hand, some waste plastics will adhere to the inner wall of the auger conveying cylinder, affecting subsequent transportation; at the same time, when the waste plastic mixture enters the conveying cylinder through the feed port, the spiral blades at the front end are always subjected to the adhesion force between the fallen waste plastic mixture and the unfallen waste plastic mixture, causing the spiral blades at the front end to be more prone to wear and deformation. A spiral propulsion device for viscoelastic materials is proposed. Utility Model Content

[0004] Based on this, the purpose of the present invention is to provide a spiral propulsion device for viscoelastic materials to solve the technical problems raised in the above background.

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. The embodiments described below with reference to the drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0023] The following describes an embodiment of the present invention based on its overall structure.

[0024] A screw propulsion device for viscoelastic materials, such as Figure 1 and Figure 2As shown, it includes a conveying cylinder body 100, a torque balancing shaft 110 is horizontally provided at the center of the inner part of the conveying cylinder body 100, one end of the torque balancing shaft 110 extends through the outside of the conveying cylinder body 100 and is installed with a motor 120, the other end of the torque balancing shaft 110 is fixedly connected to a transmission disk 130, and the transmission disk 130 is fixedly connected to a hollow balancing screw 140 near the side of the torque balancing shaft 110, and the hollow balancing screw 140 and the transmission disk 130 are connected by a fixing component 200, and a spiral sawtooth bar 150 is fixedly installed on the outer wall of the hollow balancing screw 140, and the spiral sawtooth bar 150 is in contact with the inner wall of the conveying cylinder body 100, a feed port 160 is fixedly installed on the top of one end of the conveying cylinder body 100, and a discharge port 170 is fixedly installed on the bottom of the other end of the conveying cylinder body 100, and valves are installed on the feed port 160 and the discharge port 170, and a bearing is provided at the connection between the torque balancing shaft 110 and the conveying cylinder body 100.

[0025] When the waste plastic mixture enters the conveying cylinder body 100 from the feed port 160, the motor 120 is started, and the output end of the motor 120 drives the torque balance shaft 110 to rotate, thereby driving the transmission plate 130 to rotate, and then driving the hollow balance screw 140 to rotate, and the waste plastic mixture is pushed forward. The hollow balance screw 140 has the ability to resist the adhesion of the plastic viscoelastic body. During the pushing process, there is no dead angle in the contact between the blade and the plastic viscoelastic body, which reduces the adhesion area; during the rotation process, the blade continuously rubs against the plastic viscoelastic body, forming an adhesion and friction renewal cycle. The hollow balance screw 140 is an elastic The hollow balancing screw 140 overcomes this characteristic and does not cause any conveying difficulties. The outer edge of the hollow balancing screw 140 is fixedly connected with a spiral sawtooth bar 150. During the propulsion, the spiral sawtooth bar 150 generates cutting friction with the inner wall of the conveying cylinder body 100 to clean the materials adhering to the trough body. The torque balancing shaft 110 is installed to prevent the local torque of the hollow balancing screw 140 from being too large under high temperature conditions, which causes shaking during the propulsion process, thereby improving the stability of the equipment operation.

[0026] Please refer to Figure 2 、 Figure 3 as well as Figure 4As shown, the hollow balancing spiral 140 has three sections, including a first blade 141, a second blade 142 and a third blade 143. The adjacent blades are connected by a fixing assembly 200. The butt ends of the first blade 141 and the second blade 142 and the second blade 142 and the third blade 143 are fixedly connected with a fixing block 280. The fixing blocks 280 are fixedly connected to each other by a plurality of second fixing bolts 290. The fixing assembly 200 includes a T-shaped slot 210 opened on one side of the transmission disc 130. The T-shaped slot 210 is fixed to the transmission disc 130. 10 is slidably connected with a T-shaped slider 220, and the first blade 141 is fixedly connected to a connecting block 230 at one end near the transmission disk 130. A slot 240 matching the other end of the T-shaped slider 220 is opened on the other side of the connecting block 230, and the other end of the T-shaped slider 220 is inserted into the slot 240. A plurality of threaded holes 250 are opened on the T-shaped slider 220 and the connecting block 230, and a first fixing bolt 260 is threadedly connected to the plurality of threaded holes 250. An L-shaped push rod 270 is fixedly connected to the upper surface of the T-shaped slide groove 210.

[0027] When the device is in operation for a long time, the first blade 141 will be more severely worn and deformed than the second blade 142 and the third blade 143. At this time, the conveying cylinder body 100 is opened, and the first fixing bolts 260 and the second fixing bolts 290 are removed. Then, the L-shaped push rod 270 is pushed to drive the T-shaped slider 220 to move to the other side of the T-shaped slide 210. The other end of the T-shaped slider 220 will also be separated from the slot 240. At this time, the first blade 141 can be directly removed for maintenance or replacement without the staff having to disassemble and replace the entire hollow balancing screw 140. On the one hand, it improves the staff's maintenance and replacement work efficiency of the device, and on the other hand, it reduces operating costs. Similarly, when the second blade 142 or the third blade 143 is severely deformed, it is replaced separately. Since the resistance to the third blade 143 in the second half of the mixture propulsion process is roughly constant and will not be subject to large resistance, the deformation and damage of the third blade 143 should take the longest time. Therefore, the length of the third blade 143 is longer than that of the second blade 142 and the third blade 143.

[0028] During use, after the waste plastic mixture enters the conveying cylinder body 100 from the feed port 160, the motor 120 is started, and the output end of the motor 120 drives the torque balancing shaft 110 to rotate, thereby driving the transmission plate 130 to rotate, and then driving the hollow balancing screw 140 to rotate, and the waste plastic mixture is pushed forward. The hollow balancing screw 140 has the ability to resist the adhesion of plastic viscoelastic bodies. During the pushing process, there is no dead angle in the contact between the blades and the plastic viscoelastic body, which reduces the adhesion area; during the rotation process, the blades continuously rub against the plastic viscoelastic body, forming an adhesion and friction renewal cycle. The hollow balancing screw 140 is an elastic body as a whole, and continuously repairs itself during the deformation process. , it has deformation resistance in high temperature environment, the plastic viscoelastic body is constantly deforming, resulting in resistance changes, the hollow balancing screw 140 overcomes this characteristic and will not cause transportation difficulties; the outer edge of the hollow balancing screw 140 is fixedly connected to a spiral serrated bar 150, and during propulsion, the spiral serrated bar 150 and the inner wall of the conveying cylinder body 100 generate cutting friction to clean the material adhering to the trough body; through the installed torque balancing shaft 110, the local torque of the hollow balancing screw 140 is prevented from being too large under high temperature conditions, causing shaking during the propulsion process, thereby improving the stability of the equipment operation. The parts not involved in the device are the same as the existing technology or can be implemented using existing technology.
