Description

Technical Field

[0001] This utility model relates to the field of geotextile production technology, and in particular to a feeding device for a PET extruder used in geotextile production. Background Technology

[0002] In the field of geotextile production, PET (polyethylene terephthalate) material, with its excellent physical properties such as high strength, good chemical corrosion resistance, and aging resistance, has become a key raw material for manufacturing geotextiles. As the core equipment for transforming PET raw materials into the basic form of geotextiles, the smoothness of the feeding process of the PET extruder directly affects the efficiency of the entire production process and the product quality. Currently, in geotextile production, screw conveyors are commonly used as the feeding equipment for PET extruders to transport PET raw materials to the extruder hopper. Screw conveyors play a crucial role in the raw material transportation process due to their simple structure, large conveying capacity, and good sealing performance. Through the rotation of the helical blades, they continuously and stably push the PET raw material at the feed end into the extruder hopper, providing a continuous supply of raw materials to the extruder and ensuring the continuity and stability of the extrusion process.

[0003] However, in actual production operations, there are many inconveniences in the process of pouring PET raw materials into the screw conveyor. Currently, the main feeding method is manual operation, in which operators carry the bagged PET raw materials to the feeding hopper and then pour the PET raw materials from the bags into the feeding hopper. This traditional manual feeding method places a great physical burden on the operators because there is a certain height difference between the bagged PET raw materials on the ground and the feeding hopper. Utility Model Content

[0004] The purpose of this invention is to address the numerous inconveniences in the process of pouring PET raw materials into a screw conveyor during actual production operations in existing technologies. Currently, the main feeding method is manual operation, where operators carry the bagged PET raw materials to the feeding hopper and then pour the PET raw materials from the bags into the hopper. This traditional manual feeding method, due to the height difference between the bagged PET raw materials on the ground and the feeding hopper, places a significant physical burden on the operators. Therefore, this invention proposes a feeding device for a PET extruder used in geotextile production.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A feeding device for a PET extruder used in geotextile production includes a base and a conveying cylinder. A support frame is welded to one side of the top of the base, and one side of the conveying cylinder is welded to the top of the support frame. The bottom end of the conveying cylinder is fixedly connected to the top of the base. The conveying cylinder is inclined. A discharge pipe is welded to the top of one side of the conveying cylinder and is connected to it. A feed hopper is welded to the bottom of one side of the conveying cylinder. Universal casters are fixedly installed at the four corners of the bottom of the base for easy movement. The base is equipped with a labor-saving mechanism, which allows bagged PET raw materials to be poured into the feed hopper. To prevent bags from falling into the hopper during the process of pouring PET raw materials, a fixing mechanism is also included, which can clamp and fix the bottom of the bag.

[0006] In one possible design, the labor-saving mechanism includes a frame, a fixed plate, a rotating rod, and a placement box. The frame is U-shaped, with its bottom end welded to the top of the base. One side of the fixed plate is welded to one side of the frame. Bearings I are fixedly installed on both inner walls of the frame. The two ends of the rotating rod are respectively fixedly connected to the inner ring walls of the two bearings I. Two take-up rollers are fixedly sleeved on the rotating rod. Two U-shaped plates are welded to one side of the bottom of the fixed plate. Bearings II are fixedly installed on both inner walls of the two U-shaped plates. The same guide wheel is fixedly installed on the inner ring walls of the two bearings II. A pull rope is fixedly installed on one side of the take-up roller, and the pull rope is in contact with the guide wheel. A hinge seat is welded to the top of one side of the feed hopper. The top of the placement box is hinged to the hinge seat. The bottom ends of the two pull ropes are respectively fixedly connected to both sides of the bottom of the placement box. The bottom of the placement box is in contact with the top of the base. A motor I is fixedly installed on one side of the frame. The output end of the motor I passes through one side of the frame and is fixedly connected to one end of the rotating rod.

[0007] In one possible design, the fixing mechanism includes two connecting ropes, two fixing brackets, and two bolts. One end of each connecting rope is fixedly connected to the inner wall of one side of the placement box. One side of each fixing bracket is fixedly connected to one end of the two connecting ropes. Nuts are embedded in the top of each fixing bracket. The two bolts are threadedly connected to the two nuts. The fixing bracket is U-shaped. A clamping plate is slidably connected to the inner wall of one side of the fixing bracket. A bearing III is fixedly mounted on the top of the clamping plate. The bottom end of each bolt is fixedly connected to the inner wall of the inner ring of the bearing III.

[0008] In one possible design, a shield is fixedly provided on one side of the placement box to prevent PET raw materials from falling into the gap between the placement box and the hinge seat, with one end of the shield located inside the feed hopper.

[0009] In one possible design, a conveying rod is rotatably mounted on one inner wall of the conveying cylinder, and a spiral conveying blade is welded onto the conveying rod. A motor II is fixedly mounted at one end of the conveying cylinder, and the output end of the motor II passes through one end of the conveying cylinder and is fixedly connected to one end of the conveying rod.

[0010] In one possible design, a torsion plate is welded to the top of the bolt to facilitate rotation.

[0011] In this application, the operator uses the casters located at the four corners of the base to move the entire feeding device to a suitable position near the PET extruder in the geotextile production workshop. The discharge pipe is aligned with the feed inlet of the PET extruder. Two fixing frames are placed outside the placement box. The operator places the bagged PET raw material into the placement box (initially, the bottom of the placement box is in contact with the top of the base). Then, the bottom of the PET raw material is fixed sequentially. The specific steps are: the fixing frame is manually moved to one corner of the bag, positioning the corner between the fixing frame and the clamping plate. Then, the torsion plate is rotated, causing the bolt to rotate. The rotation of the bolt causes the clamping plate to move, thus fixing one corner of the bag. The other corner is fixed, then the bag opening is opened, and motor I is started. The output end of motor I drives the rotating rod to rotate within bearing I on both sides of the frame. When the rotating rod rotates, the two winding rollers fixed on the rotating rod also rotate, starting to wind up the pull rope. During the winding process, the pull rope moves through the guide wheel inside the U-shaped plate, and then pulls upward on both sides of the bottom end of the placement box. Since the top of the placement box is hinged to the hinge seat on the top side of the feed hopper, under the pull force of the pull rope, the placement box rotates upward around the hinge seat, gradually lifting the bagged PET raw material to a suitable height above the feed hopper. During the lifting process, a shielding skin is set on one side of the placement box, with one end of the shielding skin located inside the feed hopper. This design prevents PET raw materials from falling into the gap between the placement box and the hinge seat, ensuring that the raw materials can smoothly enter the feed hopper. After the placement box lifts the bagged PET raw materials to a suitable height, the PET raw materials inside the bag enter the feed hopper (alternatively, after lifting the bagged PET raw materials to a suitable height, the operator can stop the operation of motor I, and then carefully open the bag and pour the PET raw materials into the feed hopper). The shielding material is made of PVC, and the pull rope is made of steel wire rope. The bottom two corners of the bag are clamped by clamps and fixing frames to prevent the bag from slipping into the feed hopper. After the raw materials are poured in, the operator starts motor II. The output end of motor II drives the conveyor rod inside the conveyor cylinder to rotate. The spiral conveyor blades welded to the conveyor rod rotate, transporting the PET raw material entering the conveyor cylinder from the bottom feed hopper to the top discharge pipe. As the spiral conveyor blades rotate continuously, the PET raw material is continuously and stably transported to the discharge pipe and then enters the hopper of the PET extruder, providing raw materials for the PET extruder's production. It should be noted that Motor I and Motor II require an external controller and an external power supply for operation. The casters are common lockable casters available on the market. The motor types for Motor I and Motor II can be stepper motors, servo motors, conical rotor motors, etc., and the specific type can be selected according to actual needs.

[0012] The beneficial effects of this utility model are as follows: In this invention, the feeding device of a PET extruder for geotextile production utilizes a labor-saving mechanism. Operators simply place the bagged PET raw material into the placement box, where the bottom edge initially contacts the top of the base. By starting motor I, the rotating rod rotates, causing the winding roller to wind up the pull rope. Under the tension of the pull rope, the placement box rotates upwards around the hinged seat, lifting the bagged PET raw material to a suitable height above the feeding hopper. The entire process eliminates the need for manual handling of the raw material, significantly reducing operator fatigue, lowering labor intensity, improving work efficiency, and also reducing the risk of workplace injuries due to exhaustion. In this invention, the feeding device of a PET extruder for geotextile production utilizes a fixing mechanism. After the operator places the bagged raw material into the placement box, rotating the torsion plate drives the bolts to rotate, causing the clamping plate to move and fixing the two bottom corners of the bag between the fixing frame and the clamping plate. During the lifting process of the placement box, the fixing mechanism firmly clamps the bag, preventing it from slipping into the feeding hopper, ensuring smooth raw material conveying, guaranteeing the continuity and stability of production, and reducing equipment failures and safety accidents.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0016] In one embodiment: Refer to Figure 1-4A feeding device includes a base 1, a conveyor cylinder 3, a labor-saving mechanism, and a fixing mechanism. The base 1 serves as the basic support structure for the entire device. A support frame 2 is welded to one side of its top. One side of the conveyor cylinder 3 is welded to the top of the support frame 2, and its bottom end is fixedly connected to the top of the base 1, arranged at an angle to facilitate raw material conveying. A discharge pipe is welded to and connected to one side of the top of the conveyor cylinder 3 for conveying raw materials to a PET extruder; a feed hopper 9 is welded to the bottom of one side as the raw material inlet. Casters are fixedly installed at the four corners of the base 1 for easy movement of the device. The labor-saving mechanism lifts bagged PET raw materials into the feed hopper 9, while the fixing mechanism prevents bags from falling into the feed hopper 9 during the material pouring process.

[0017] The labor-saving mechanism includes a U-shaped frame 4, the bottom of which is welded to the top of the base 1, providing stable support for the entire mechanism. A fixing plate 6 is welded to one side of the frame 4, serving to connect and fix other components. Bearings I are fixedly installed on the inner walls of both sides of the frame 4. The two ends of the rotating rod 5 are fixedly connected to the inner rings of the two bearings I, allowing the rotating rod 5 to rotate stably within the frame 4. Two take-up rollers 12 are fixedly sleeved on the rotating rod 5. When the rotating rod 5 rotates, the take-up rollers 12 rotate accordingly, realizing the winding and unwinding of the pull rope 8. Two U-shaped plates 7 are welded to one side of the bottom of the fixing plate 6. Bearings II are fixedly installed on the inner walls of both sides of the U-shaped plates 7. The same guide wheel 13 is fixedly installed on the inner ring of the two bearings II. A pull rope 8 is fixedly installed on one side of the take-up roller 12. The pull rope 8 contacts the guide wheel 13, which changes the direction of the pull rope 8, allowing it to smoothly pull the placement box 10. A hinge seat is welded to the top of one side of the feed hopper 9. The top of the placement box 10 is hinged to the hinge seat, allowing the placement box 10 to rotate around the hinge seat. The bottom ends of the two pull ropes 8 are fixedly connected to the two sides of the bottom end of the placement box 10, and the bottom end of the placement box 10 is initially in contact with the top of the base 1. A motor I 11 is fixedly installed on one side of the frame 4. The output end of the motor I 11 passes through one side of the frame 4 and is fixedly connected to one end of the rotating rod 5 through a coupling.

[0018] In actual operation, the operator places the bagged PET raw material into the placement box 10, starts the motor I 11, and the output end of the motor I 11 drives the rotating rod 5 to rotate in the bearing I. The winding roller 12 on the rotating rod 5 rotates accordingly and begins to wind up the pull rope 8. After the pull rope 8 changes direction through the guide wheel 13 in the U-shaped plate 7, it pulls upward on both sides of the bottom end of the placement box 10. Since the top of the placement box 10 is hinged to the hinge seat, the placement box 10 will rotate upward around the hinge seat, gradually lifting the bagged PET raw material to a suitable height above the feed hopper 9. After the raw material is poured into the feed hopper 9, the motor I 11 is reversed, the rotating rod 5 drives the winding roller 12 to unwind the pull rope 8, and the placement box 10 returns to its initial position under the action of gravity.

[0019] The fixing mechanism includes two connecting ropes 14 and two fixing brackets 15. One end of each connecting rope 14 is fixedly connected to the inner wall of one side of the placement box 10. One side of each fixing bracket 15 is fixedly connected to the other end of the two connecting ropes 14, thus connecting the fixing brackets 15 to the placement box 10 via the connecting ropes 14. Nuts are embedded in the top of each fixing bracket 15, and two bolts 16 are threadedly connected to the two nuts. The fixing bracket 15 is U-shaped, with a clamping plate 17 slidably connected to one side of its inner wall. A bearing III is fixedly mounted on the top of the clamping plate 17, and the bottom end of each bolt 16 is fixedly connected to the inner wall of the inner ring of the bearing III. A torsion plate for easy rotation is welded to the top of each bolt 16.

[0020] During operation, the operator places the fixing frame 15 outside the placement box 10, and manually lifts the fixing frame 15 to one corner of the bag, positioning that corner between the fixing frame 15 and the clamping plate 17. Then, the operator rotates the torsion plate, which causes the bolt 16 to rotate. Since the bolt 16 is threadedly connected to the nut, and its bottom end is connected to the clamping plate 17 via bearing III, the bolt 16 moves downward as it rotates, pushing the clamping plate 17 towards the fixing frame 15, thereby securing one corner of the bag. The other corner of the bag is secured in the same way. This prevents the bag from slipping into the feed hopper 9 during the lifting of the placement box 10 and the pouring of raw materials. The connecting rope 14 can also be made of steel wire rope.

[0021] This application is for the field of geotextile production, but can also be used in other fields applicable to this application.

[0022] In another embodiment: Reference Figure 1-4 A feeding device for a PET extruder used in geotextile production, which is applied in the field of geotextile production. A shielding skin 18 is fixedly installed on one side of the placement box 10. The shielding skin 18 is made of PVC material and has a certain degree of flexibility and durability. One end of the shielding skin 18 is located inside the feed hopper 9. When the placement box 10 rotates upward around the hinge seat to lift the bagged PET raw material, the shielding skin 18 can cover the gap between the placement box 10 and the hinge seat, preventing the PET raw material from falling into the gap and ensuring that the raw material can smoothly enter the feed hopper 9.

[0023] A conveying rod is rotatably mounted on the inner wall of one side of the conveying cylinder 3. A spiral conveying blade is welded onto the conveying rod. A motor II is fixedly mounted on one end of the conveying cylinder 3. The output end of the motor II passes through one end of the conveying cylinder 3 and is fixedly connected to one end of the conveying rod through a coupling.

[0024] When bagged PET raw material enters conveyor cylinder 3 through feed hopper 9, motor II is started. The output of motor II drives the conveyor rod to rotate, and the spiral conveyor blades on the conveyor rod rotate accordingly. During the rotation of the spiral conveyor blades, a forward thrust is generated on the raw material, conveying it from the feed hopper 9 at the bottom of conveyor cylinder 3 towards the discharge pipe welded at the top. As the spiral conveyor blades continue to rotate, the PET raw material is continuously and stably conveyed to the discharge pipe, and then enters the hopper of the PET extruder through the discharge pipe, providing raw materials for the production of the PET extruder.

[0025] However, as is well known to those skilled in the art, the working principles and wiring methods of motor I11 and motor II are conventional methods or common knowledge, and will not be elaborated here. Those skilled in the art can make any selections according to their needs or convenience.

[0026] The accompanying drawings in this application are for illustrative purposes only. The dimensions and shapes of the components shown are not actual limitations but are merely schematic representations. In actual implementation, the components can be reasonably configured and adjusted according to specific needs and actual conditions.

[0027] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
