Technical Field

[0001] This invention relates to the field of PE material modification technology, specifically to a PE material modification equipment and modification process. Background Technology

[0002] Polyethylene (PE) is a thermoplastic resin obtained by polymerizing ethylene. Polyethylene is odorless, non-toxic, and has a waxy feel. It possesses excellent low-temperature resistance (minimum operating temperature can reach -100 to -70℃), good chemical stability, and is resistant to most acids and alkalis (but not resistant to oxidizing acids; therefore, antioxidants need to be added). It is insoluble in common solvents at room temperature, has low water absorption, and excellent electrical insulation properties.

[0003] In the existing polyethylene production process, polyethylene needs to be mixed with different materials according to different needs to produce materials with different properties. For example, PE alloy modified materials have advantages such as high strength. PE alloy modified materials need to be mixed with other materials during the production process. However, the spiral conveyor mixing equipment on the market has the problem of incomplete modification of PE materials and low processing efficiency when mixing small amounts of liquid and large amounts of solid raw materials, resulting in low final PE material modification processing efficiency.

An observation frame is fixed at the end of the machine body away from the drive motor, and an outlet is fixed at the bottom of the observation frame.

[0015] Optionally, the flat screen mechanism includes a movable screen plate, which is slidably installed on the inner wall of the feed inlet. Two sets of support plates are fixed on the side wall at the bottom of the movable screen plate. A fixing block is fixed on the side wall of the feed inlet to limit the position of the support plate and the movable screen plate. A protrusion is fixed on the side wall of the transmission auger, and when the transmission auger rotates, the protrusion contacts the bottom end of the support plate.

[0016] Optionally, the grinding mechanism is arranged in multiple arrays, and the side wall of the machine body is fixed with a column that matches the triangular block.

[0017] Optionally, a sliding groove is provided on the side wall of the fixed ring, the inner wall of the sliding groove is fixed to one end of the spring, the other end of the spring is fixed to the side wall of the base plate, and the base plate is welded to the bottom of the movable stirring blade.

[0018] This invention also provides a modification process for a PE material modification device, comprising the following steps:

[0019] Step S1: Determine the proportions of the PE material raw materials that need to be modified;

[0023] The present invention has the following beneficial effects:

[0024] 1. The PE material modification equipment and modification process, during the process of stirring and conveying the PE material by the transmission auger, uses three sets of moving stirring blades and fixed stirring blades to perform secondary crushing and modification treatment on the PE material. In addition, during the rotation of the outer ring, the column and the triangular block contact and squeeze, and the moving stirring blades move relative to the fixed stirring blades to achieve the effect of stirring and grinding, thereby improving the modification effect on the PE material.

[0025] 2. In the PE material modification equipment and process, during the movement of the movable stirring blade towards the fixed stirring blade, the inclined surface of the connecting rod comes into contact with the movable stirring blade and drives the movable stirring blade and the connecting rod to move upward, at which time the elastic strip is stretched; during the movement of the movable stirring blade away from the fixed stirring blade, the movable stirring blade moves towards the fixed ring under the tension of the elastic strip, realizing the reciprocating up and down movement of the movable stirring blade, which promotes the efficiency of PE material mixing and modification.

[0026] 3. In this PE material modification equipment and process, while the drive auger is rotating, the protrusions on the side wall of the drive auger contact and squeeze the support plate, causing the movable screen plate to move up and down slightly. This allows for screening of the material at the feed inlet, preventing excessive material from clogging the feed inlet and ensuring the processing efficiency of the equipment.

[0027] 4. The PE material modification equipment and modification process, by setting a spring on the sliding groove, after the column and the triangular block have finished contacting and pressing, the movable stirring blade is reset under the action of the spring, so that the movable stirring blade can periodically oscillate back and forth, ensuring the modification efficiency of PE material.

[0038] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0039] Please see Figures 1-9This invention provides a technical solution: a PE material modification device, including a machine body 1, a support base 4 welded to the bottom of the machine body 1, a drive motor 2 fixed on the side wall of the machine body 1, a top cover 10 detachably installed on the top of the machine body 1, a drive modification mechanism 7 provided inside the machine body 1, the drive motor 2 outputs power to the drive modification mechanism 7, the drive modification mechanism 7 includes a drive shaft 71, the end of the drive shaft 71 is fixed to the output end of the drive motor 2, a transmission auger 72 is fixed on the drive shaft 71, and a grinding mechanism 8 for grinding PE material is provided inside the machine body 1, the grinding mechanism 8 includes: an outer ring 81, a transmission rod 82, an inclined groove 83, a triangular block 84, a movable stirring blade 85, a fixed stirring blade 86, a fixed ring 87, a fixed plate 88, a column 89, a sliding groove 810, and a spring 811.

[0040] The fixed ring 87 is fixed to the drive shaft 71, and a fixed stirring blade 86 is fixed to the side wall of the fixed ring 87. The movable stirring blade 85 includes a first movable stirring blade 851, which is hollow inside, and a second movable stirring blade 852 is slidably installed inside the first movable stirring blade 851. The movable stirring blade 85 is slidably installed on the outer wall of the fixed ring 87. A connecting rod 853 is welded to the bottom of the second movable stirring blade 852. A fixing plate 88 adapted to the connecting rod 853 is fixed to the side wall of the fixed ring 87. A protruding rod is fixed to the side wall of the first movable stirring blade 851. The protruding rod is fixed to one end of the elastic strip 855, and the other end of the elastic strip 855 is fixed to the side wall of the second movable stirring blade 852. During the movement of the first movable stirring blade 851 toward the fixed stirring blade 86, the inclined surface of the connecting rod 853 contacts the second movable stirring blade 852, causing the second movable stirring blade 852 and the connecting rod 853 to move upward. At this time, the elastic strip 855 is stretched. During the movement of the first movable stirring blade 851 away from the fixed stirring blade 86, the second movable stirring blade 852 moves toward the fixed ring 87 under the pulling force of the elastic strip 855, realizing the reciprocating up and down movement of the second movable stirring blade 852, which promotes the efficiency of PE material mixing and modification.

[0041] Furthermore, one end of the transmission rod 82 is fixed to the outer wall of the movable stirring blade 851, and the other end is fixed with a triangular block 84; the transmission auger 72 passes through the outer ring 81, and a slanted groove 83 is provided on the side wall of the outer ring 81, through which the transmission rod 82 passes. A rectangular groove 74 is provided on the side wall of the transmission auger 72 for the transmission rod 82 to move, and a set of transmission rods 82 passes through the rectangular groove 74.

[0042] The movable stirring blade 85, the fixed stirring blade 86, and the transmission rod 82 are arranged in three arrays. During the process of stirring, conveying, and modifying the PE material by the transmission auger 72, the PE material is subjected to secondary crushing and modification treatment by the three sets of movable stirring blades 85 and fixed stirring blades 86. During the rotation of the outer ring 81, the column 89 contacts and squeezes the triangular block 84, and the movable stirring blade 851 moves relative to the fixed stirring blade 86, which plays a role in stirring and grinding, thereby improving the modification effect on the PE material.

[0043] It is worth noting that the end of the machine body 1 closest to the drive motor 2 has an integrally formed inlet 3. The inlet 3 is equipped with a flat screen mechanism for screening PE materials. The end of the machine body 1 away from the drive motor 2 is fixed with an observation frame 5, and the bottom of the observation frame 5 is fixed with an outlet 6. The flat screen mechanism includes a movable screen plate 91, which is slidably installed on the inner wall of the inlet 3. Two sets of support plates 92 are fixed on the side wall at the bottom of the movable screen plate 91. A fixing block 93 is fixed on the side wall of the inlet 3 to limit the position of the support plate 92 and the movable screen plate 91. A protrusion 73 is fixed on the side wall of the transmission auger 72, and when the transmission auger 72 rotates, the protrusion 73 contacts the bottom end of the support plate 92. While the drive auger 72 is rotating, the protrusions 73 on the side wall of the drive auger 72 contact and press against the support plate 92, causing the movable screen plate 91 to move up and down slightly. This allows for screening of the material at the feed inlet, preventing excessive material from clogging the feed inlet and ensuring the processing efficiency of the equipment.

[0044] In addition, multiple grinding mechanisms 8 are arranged in an array, and a column 89 adapted to the triangular block 84 is fixed on the side wall of the machine body 1. A sliding groove 810 is provided on the side wall of the fixing ring 87. The inner wall of the sliding groove 810 is fixed to one end of the spring 811, and the other end of the spring 811 is fixed to the side wall of the base plate 854. The base plate 854 is welded to the bottom of the movable stirring blade 851. By setting the spring 811 on the sliding groove 810, after the column 89 and the triangular block 84 have finished contacting and pressing, the movable stirring blade 851 is reset under the action of the spring 811, so that the movable stirring blade 851 can periodically oscillate back and forth, ensuring the modification efficiency of PE material.

[0045] In this embodiment, the drive shaft 71 has a built-in heating wire for electrothermal operation. The heating wire of the drive shaft 71 is electrically connected to the drive motor 2 with a 220V AC mains power supply.

[0046] As one application of this embodiment: during the process of stirring, conveying and modifying PE material by the transmission auger 72, the PE material is subjected to secondary crushing and modification treatment by three sets of movable stirring blades 85 and fixed stirring blades 86. During the rotation of the outer ring 81, the column 89 contacts and squeezes the triangular block 84, and the movable stirring blade 1 851 moves relative to the fixed stirring blade 86, which plays a role in stirring and grinding, thereby improving the modification effect on the PE material. During the process of the movable stirring blade 1 851 moving towards the fixed stirring blade 86, the inclined surface of the connecting rod 853 contacts the movable stirring blade 2 852 and drives the movable stirring blade 2 852 and the connecting rod 853 to move upward. At this time, the elastic strip 855 is stretched.

[0047] Furthermore, as the movable stirring blade 851 moves away from the fixed stirring blade 86, the movable stirring blade 852 moves towards the fixed ring 87 under the tension of the elastic strip 855, realizing the reciprocating up-and-down movement of the movable stirring blade 852, which promotes the efficiency of PE material mixing and modification. By setting a spring 811 on the sliding groove 810, after the column 89 and the triangular block 84 have finished contacting and pressing, the movable stirring blade 851 is reset under the action of the spring 811, so that the movable stirring blade 851 can periodically oscillate back and forth, ensuring the modification efficiency of PE material.

[0048] While the drive auger 72 rotates, the protrusions 73 on its side wall contact and press against the support plate 92, causing the movable screen plate 91 to move slightly up and down. This allows for screening of the material at the feed inlet, preventing excessive material from clogging the inlet and ensuring the equipment's processing efficiency.

[0049] This embodiment also proposes a modification process for a PE material modification device, including the following steps:

[0050] Step S1: Determine the proportions of the PE material raw materials that need to be modified;

[0051] Step S2: Determine the modification environment for the PE material to be modified. If a high-temperature environment is required, connect the heating wire in the drive shaft 71 to the mains power.

[0052] Step S3: Start the drive motor 2 and pour the PE material raw material to be modified into the feed port 3. The PE material is conveyed by the transmission auger 72. The PE material is driven and stirred by the transmission auger 72 and then ground by the grinding mechanism 8. Finally, it is discharged through the discharge port 6.

[0053] Step S4: Pack and store the PE material.

[0054] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
