Description

Technical Field

[0001] This invention belongs to the technical field of plastic pelletizing equipment, specifically an adjustable pelletizing system for plastic particles. Background Technology

[0002] Plastic particles, also known as plastic granules or plastic raw material granules, are the basic raw materials in the plastics processing industry. They are usually the processed form of plastic resins used in further molding, extrusion, injection molding and other production processes. Plastic particles can be classified according to different plastic types, molecular structures, additives and colors. Some common plastic particles include: polyethylene (PE), polypropylene (PP), polyvinyl chloride (PVC), polystyrene (PS), polyethylene terephthalate (PET), polycarbonate (PC), nylon (PA) and ABS resin.

[0003] Extruders are a type of plastic pelletizing machinery, but most existing plastic pellet extruders suffer from inconvenience in movement. To facilitate movement, pulleys are usually installed at the bottom of the device, relying on them for movement. However, since the pulleys are only in contact with the ground for support, the extruder's stability during operation is poor, making it prone to displacement. Using outriggers for support would further hinder movement and reduce practicality. In addition, existing extruders are all open structures, and when the extruder is not in use, the main components are exposed and easily accumulate dust, requiring cleaning before reuse. Therefore, improvements are needed to address these issues. Summary of the Invention

[0028] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0029] Example 1, by Figures 1 to 9 The present invention includes a mounting base 1, characterized in that: a screw extruder granulator 2 is mounted on the top of the mounting base 1; four support legs 3 are fixedly mounted on the bottom of the mounting base 1; four rollers 4 for movement are mounted on the bottom of the mounting base 1; rotatable and adjustable long side panels 5 are mounted on the upper parts of both sides of the mounting base 1; rotatable and adjustable short side panels 6 are mounted on both ends of the two long side panels 5; and rotatable and adjustable top panels 7 are mounted on the top of the two long side panels 5. The two long side panels 5, four short side panels 6, and two... The top panel 7 and the mounting base 1 can effectively protect the screw extruder granulator 2. Any long side panel 5 is connected to the two short side panels 6 and the top panel 7 through a rotation adjustment mechanism. The upper part of the mounting base 1 is equipped with an adjustment power end, which is connected to the two rotation adjustment mechanisms. The bottom of the mounting base 1 is provided with an adjustment groove 8. The inside of the adjustment groove 8 is equipped with a roller mounting structure and a power adjustment structure. The four rollers 4 are connected to the roller mounting structure, and the power adjustment structure is connected to the roller mounting structure.

[0030] In Embodiment 2, based on Embodiment 1, the roller mounting structure includes two first mounting slots 9 and two second mounting slots 10. The two first mounting slots 9 and two second mounting slots 10 are respectively located at the lower parts of both ends of the adjusting slot 8. A first adjusting arm 11 is rotatably connected inside each of the two first mounting slots 9, and a second adjusting arm 12 is rotatably connected inside each of the two second mounting slots 10. Four rollers 4 are respectively mounted at one end of the bottom of the two first adjusting arms 11 and the two second adjusting arms 12. The two second adjusting arms 12 are respectively located at the two first adjusting arms 11 and 12. The top of the first adjusting arm 11 allows for the effective installation of the roller 4; one end of each first adjusting arm 11 is provided with a connecting groove 24, and a fixing pin 25 is fixedly installed inside each of the two connecting grooves 24. A connecting block 28 is rotatably connected to the surface of each of the two fixing pins 25; the other end of the bottom of each of the two second adjusting arms 12 is provided with a sliding groove 26, and a sliding rod 27 is fixedly connected inside each of the two sliding grooves 26; the upper part of each of the two connecting blocks 28 is slidably sleeved on the surface of each of the two sliding rods 27, so that the first adjusting arm 11 and the second adjusting arm 12 can be adjusted synchronously.

[0031] Each of the two first adjusting arms 11 has a fixed limiting block 13 fixedly installed on one side facing away from each other. Each of the two second adjusting arms 12 has a connecting hook 14 rotatably connected to one end facing away from each other. The lower parts of the two connecting hooks 14 are hooked to the two fixed limiting blocks 13 respectively, and the upper parts of the two connecting hooks 14 are fixedly connected to the two second adjusting arms 12 with return springs 15 respectively. Each of the two first adjusting arms 11 has a pushing adjusting block 16 fixedly installed at the middle of its top, thus ensuring the stability and firmness of the connection between the first adjusting arms 11 and the second adjusting arms 12. The power adjustment structure includes two mounting rods 17 fixedly installed at the middle of the top of the adjusting groove 8, and a moving block 18 slidably installed between the surfaces of the two mounting rods 17. An electric cylinder 19 is installed in the middle of the upper part of one end of the adjusting groove 8. The electric cylinder 19 is located between two mounting rods 17. The telescopic end of the electric cylinder 19 is fixedly connected to the middle of one end of the moving block 18. A first pressing block 20 is fixedly installed at one end of both sides of the moving block 18. The first pressing block 20 is located on one side of the upper part of the pushing adjusting block 16. A second pressing block 21 is fixedly installed at the other end of both sides of the moving block 18. A one-way mounting groove 22 is opened at the lower part of the two second pressing blocks 21. A movable pressing block 23 is rotatably connected inside the two one-way mounting grooves 22. The two movable pressing blocks 23 are located on one side of the upper part of the two connecting hooks 14, so that the first adjusting arm 11 and the second adjusting arm 12 can be effectively rotated and adjusted.

[0032] When the device needs to be moved, the four rollers 4 are brought into contact with the ground and the four support legs 3 are raised away from the ground. The device can then be moved by the rolling of the four rollers 4. When the device needs to be used, the support legs 3 need to be brought into contact with the ground and the four rollers 4 need to be raised away from the ground.

[0033] At this time, by activating the electric cylinder 19 to extend, the electric cylinder 19 pushes the moving block 18 to move on the surface of the two mounting rods 17. The movement of the moving block 18 will drive the two first pressing blocks 20 and the two second pressing blocks 21 to move, causing the first pressing blocks 20 to move and separate from the pushing adjustment block 16. At the same time, the second pressing blocks 21 drive the movable pressing block 23 to move through the one-way mounting groove 22, thus pressing the upper part of the connecting hook 14. This causes the upper part of the two connecting hooks 14 to rotate. The rotation of the two connecting hooks 14 will cause the hook ends at the bottom to separate from the two fixed limiting round blocks 13. Then, the continuous movement of the two second pressing blocks 21 will press and push the two adjusting blocks 16, causing the two adjusting blocks 16 to drive the two first adjusting arms 11 to rotate. The rotation of the two first adjusting arms 11 will drive the two second adjusting arms 12 to rotate through the fixing pin 25 and the connecting block 28. Finally, the rotation of the two first adjusting arms 11 and the two second adjusting arms 12 will drive the rollers 4 to move upward, causing the mounting base 1 to drive the four support legs 3 to move downward, so that the four support legs 3 contact the ground. At the same time, the four rollers 4 are raised away from the ground. At this time, the device can be used stably.

[0034] When movement is required, the electric cylinder 19 is retracted, causing the moving block 18 to move the two first pressing blocks 20 and the two second pressing blocks 21. The movement of the two first pressing blocks 20 will cause the two pushing adjustment blocks 16 to rotate, which in turn causes the two first adjusting arms 11 to rotate and move downward. The rotation and downward movement of the two first adjusting arms 11 will cause the two second adjusting arms 12 to rotate and move downward. Finally, when the two second adjusting arms 12 press on the top of the two first adjusting arms 11, the lower part of the two connecting hooks 14 is hooked and connected to the upper part of the two fixed limiting round blocks 13. At the same time, the first pressing blocks 20 are in contact with the upper part of the pushing adjustment blocks 16 and are limited, and the four rollers 4 are in contact with the ground and the four support legs 3 are raised away from the ground.

[0035] In Embodiment 3, based on Embodiment 1, both ends of the two long side panels 5 are provided with first connecting grooves 29. The short side panels 6 have an inverted convex structure, and a transmission slot 30 is provided in the middle of one end of each short side panel 6. A first connecting shaft 31 is fixedly connected to one end of the short side panel 6, passing through the transmission slot 30. The first connecting shaft 31 is rotatably connected to the top of the first connecting groove 29. A first bevel gear 35 is fixedly connected to the surface of the first connecting shaft 31 located inside the transmission slot 30. The two short side panels on the same long side panel 5... The first bevel gear 35 on plate 6 is staggered vertically. The top of each of the two long side panels 5 is provided with a second connecting groove 32. Two strips 33 are fixedly connected to the opposite sides of the bottom of the two top panels 7. A second connecting shaft 34 is fixedly connected between the middle of the two strips 33. The second connecting shaft 34 is rotatably connected inside the second connecting groove 32. A large bevel gear 36 is fixedly connected to the surface of the second connecting shaft 34 located between the two strips 33, so that the short side panel 6 and the top panel 7 can be installed effectively.

[0036] The rotation adjustment mechanism includes an inner cavity 37 formed in the middle of the two long side panels 5. A third rotating shaft 38 is vertically rotatably connected to the middle of each of the two long side panels 5. Both third rotating shafts 38 pass through the two inner cavities 37. A small bevel gear 39 that meshes with a large bevel gear 36 is fixedly connected to the top of each of the two third rotating shafts 38. A second bevel gear 40 is fixedly installed on the surface of each of the third rotating shafts 38 inside the inner cavity 37. A fourth rotating shaft 41 is horizontally rotatably connected to both sides of the middle of the two long side panels 5. A third bevel gear 42 that meshes with the second bevel gear 40 is fixedly connected to the end of each of the two fourth rotating shafts 41 inside the inner cavity 37. One end of each of the two fourth rotating shafts 41 extends into the interior of two first connecting grooves 29 on the long side panels 5 and is fixedly connected to a fourth bevel gear 43. The fourth bevel gear 43 meshes with the first bevel gear 35, thereby enabling effective synchronous adjustment of the two short side panels 6 and the top panel 7.

[0037] The bottom of each of the two third rotating shafts 38 is fixedly mounted with a fifth bevel gear 44. The middle of the upper part of both sides of the mounting base 1 is fixedly mounted with a first fixing block 45. An arc-shaped conical rack 46 is fixedly mounted on one side of each first fixing block 45. The arc-shaped conical rack 46 meshes with the fifth bevel gear 44, thereby enabling effective transmission. The bottom of each of the two long side panels 5 is fixedly connected with a pair of second fixing blocks 47. The adjustment power end includes rotating rods 48 rotatably connected to the upper part of both sides of the mounting base 1. The two rotating rods 48 pass through the two first fixing blocks 45 respectively. The two pairs of second fixing blocks 47 are fixedly connected to the two rotating rods 48 respectively. A sixth bevel gear 49 is fixedly connected to one end of each of the two rotating rods 48. A double-output shaft motor 50 is mounted on the upper part of one end of the mounting base 1. The two ends of the double-output shaft motor 50 are fixedly connected with a seventh bevel gear 51. The two seventh bevel gears 51 mesh with the two sixth bevel gears 49 respectively, thereby enabling effective adjustment.

[0038] When the screw extrusion granulator 2 is needed, the two seventh bevel gears 51 are driven to rotate 180° to the two sixth bevel gears 49 by starting the dual output shaft motor 50. The rotation of the two sixth bevel gears 49 will drive the two rotating rods 48 to rotate synchronously in opposite directions. The two rotating rods 48 rotating in opposite directions will drive the two long side panels 5 to rotate 180° through the two pairs of second fixed blocks 47. The rotation of the two long side panels 5 will drive the two short side panels 6 and the top panel 7 on them to rotate 180°.

[0039] The 180° rotation of the two long side panels 5 will cause the fifth bevel gear 44 to roll along a 180° trajectory on the surface of the arc-shaped conical rack 46. The 180° rotation of the fifth bevel gear 44 will cause the third rotating shaft 38 to rotate 180°. The 180° rotation of the third rotating shaft 38 will cause the second bevel gear 40 and the small bevel gear 39 to rotate 180°. The 180° rotation of the small bevel gear 39 will drive the large bevel gear 36 to rotate 90°. The 90° rotation of the large bevel gear 36 will drive the top panel 7 to rotate 90° through the second connecting shaft 34 and the two strips 33, so that the top panel 7 is in contact with the long side panels 5 and parallel to them. The 180° rotation of the long side panels 5 will be in contact with the side of the mounting base 1 and parallel to it.

[0040] Simultaneously, the 180° rotation of the second bevel gear 40 will drive the two third bevel gears 42 to rotate 180°, causing the two fourth rotating shafts 41 to rotate 180°. The 180° rotation of the two fourth rotating shafts 41 will drive the fourth bevel gear 43 to rotate 180°. The 180° rotation of the fourth bevel gear 43 will drive the first bevel gear 35 to rotate 180°. The 180° rotation of the first bevel gear 35 will drive the first connecting shaft 31 and the short side plate 6 to rotate 180°. Finally, the 180° rotation of the long side plate 5 will drive the short side plate 6 to move, and the 180° rotation of the short side plate 6 itself will make the short side plate 6 fit parallel to the end face of the mounting base 1. This will make the two top plates 7 and the four short side plates 6 fit parallel to the side and end face of the mounting base 1, thus facilitating the use of the screw extrusion granulator 2.
