Description

Technical Field

[0001] This utility model relates to the field of mechanical equipment technology, specifically a feeder for long fiber reinforced TPU. Background Technology

[0002] Vacuum feeders, also known as vacuum conveyors, vacuum feeders, vacuum suction machines, or solid feeders, are dust-free, closed-loop conveying equipment that uses vacuum suction to transport granular and powdery materials. They are widely used in the raw material conveying industry for equipment such as injection molding machines and extruders. They are easy to install, simple to operate, have strong long-distance conveying capacity, stable production, and reliable operation, making them auxiliary equipment for achieving fully automated production.

[0003] A typical material conveyor consists of a body and a suction pipe mounted on the body. The inlet of the suction pipe is usually made of metal. In use, the suction pipe is inserted into a material box containing material. The material conveyor uses the pressure difference between the vacuum and the ambient space to create a flow of gas inside the suction pipe, which drives the movement of granular material, thereby completing the material conveying.

[0004] However, when using the suction tube to extract materials, it is necessary to lift part of the suction tube before holding it by hand. Holding it for a long time can easily cause fatigue for the user and affect work efficiency.

[0005] Based on this, this utility model designs a feeder for long fiber reinforced TPU to solve the above problems. Utility Model Content

[0006] To achieve the above objectives, the present invention provides the following technical solution: a fixing ring is fixedly sleeved on the suction pipe, a support frame is provided on the fixing ring, the support frame is located on both sides of the suction pipe, a limit block is fixedly provided on the support frame, a clearance groove is opened on the lower surface of the support frame, a connecting rod is fixedly provided in the clearance groove, a roller is rotatably provided on the connecting rod, and when the roller starts to slide along the top of the box, the suction pipe slides in the box.

[0007] By adopting the above technical solution, the support frame is placed on the top of the box, so that the limiting block presses against the side of the box. The support frame supports the suction pipe upward, freeing the user's hands and making the use of the suction pipe more convenient. When sucking up materials, if it is necessary to move the suction pipe, the support frame can be pushed directly, so that the rollers on the support frame roll on the top of the box, making the movement of the suction pipe easier and less strenuous.

[0008] Preferably, the fixing ring has a sliding groove, and the support frame is slidably connected in the sliding groove.

[0009] By adopting the above technical solution, the suction tube can slide on the support, increasing the movable space of the suction tube. When not in use, the support frame can be pushed to slide out from the limit operation point, making it easy to store the suction tube.

[0010] Preferably, the fixed ring has clearance holes on both sides, a telescopic rod is fixedly installed in the clearance holes, a positioning block is fixedly installed at the other end of the telescopic rod, and a plurality of limiting grooves are opened on both sides of the support frame. When the positioning block is located in the positioning groove, the suction pipe is fixed on the support frame.

[0011] By adopting the above technical solution, the pressure limiting block can be pressed into the limiting groove when there is no need to move the suction pipe, so that the suction pipe can be fixed on the support frame at any time, which increases the convenience of using the support frame.

[0012] Preferably, the support frame is arched.

[0013] By adopting the above technical solutions, the arched support frame can better distribute and bear the load, thus improving the stability of the structure.

[0014] Preferably, a pressing block is fixedly provided in the limiting groove.

[0015] By adopting the above technical solution, the connection between the limiting block and the limiting groove is made tighter, further enhancing the stability of the structure.

[0016] In summary, this application has the following beneficial technical effects: placing the support frame on the top of the box allows the limiting block to press against the side of the box, and the support frame supports the suction pipe upwards, freeing the user's hands and making the suction pipe easier to use. When sucking up materials, if it is necessary to move the suction pipe, the support frame can be pushed directly, causing the rollers on the support frame to roll on the top of the box, making the movement of the suction pipe easier and less strenuous.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0025] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0026] A feeder for long fiber reinforced TPU includes a body 1 and a feed pipe 2 disposed on the body 1. A fixing ring 4 is fixedly sleeved on the feed pipe 2, and a support frame 5 is disposed on the fixing ring 4. The support frame 5 is located on both sides of the feed pipe 2. A plurality of limiting blocks 10 are fixedly disposed on the support frame 5. A clearance groove 11 is opened on the lower surface of the support frame 5. A connecting rod is fixedly disposed in the clearance groove 11, and a roller 12 is rotatably disposed on the connecting rod.

[0027] In use, the suction tube 2 is placed into the box 3, and the support frame 5 on the suction tube 2 is placed across the opening of the box 3. The box 3 is positioned between two limiting blocks 10 on the support frame 5. The support frame 5 supports the suction tube 2 upwards, freeing the user's hands. Several limiting blocks 10 can be matched with multiple boxes 3 of different widths. The tip of the suction tube 2 extends into the box 3 to suck up materials. When sucking up materials, the suction tube 2 can be pushed left and right. The support frame 5 begins to move on the top of the box 3. The rollers 12 on the support frame 5 begin to rotate along the top of the box 3, making the movement of the support frame 5 easier. The suction tube 2, which moves left and right, can more comprehensively suck up the materials in the box 3, making the use of the device easier and more convenient.

[0028] The fixed ring 4 has a sliding groove 13, and the support frame 5 is slidably connected in the sliding groove 13. The fixed ring 4 has clearance holes 6 on both sides, and a telescopic rod 7 is fixedly installed in the clearance holes 6. A positioning block 8 is fixedly installed at the other end of the telescopic rod 7. The support frame 5 has several limiting grooves 9 on both sides. Pulling the limiting block 10 causes the telescopic rod 7 to extend out of the clearance hole 6, and the limiting block 10 to move away from the limiting groove 9. The limitation between the support frame 5 and the fixed ring 4 is released, and the fixed ring 4 can drive the suction pipe 2 to slide back and forth on the support frame 5. This increases the range of motion of the suction pipe 2 without the need for hand-holding, so that the suction pipe 2 and the box 3 can always maintain a relative motion state, making the use of the suction machine more flexible and convenient.

[0029] The support frame 5 is designed in an arch shape. When the fixing ring 4 slides, the arched support frame 5 can better distribute and bear the load, which improves the stability of the structure and increases the service life of the support frame 5. A pressing block is fixedly installed in the limiting groove 9. The pressing block is set on both sides of the limiting groove 9. When the limiting block 10 enters the limiting groove 9, the pressing block presses against the limiting groove 9, making the connection between the limiting block 10 and the limiting groove 9 tighter and further enhancing the stability of the structure.

[0030] The implementation principle of this embodiment is as follows: When in use, the suction tube 2 is placed into the box 3, and the support frame 5 on the suction tube 2 is placed across the opening of the box 3. The box 3 is limited between the two limiting blocks 10 on the support frame 5. The support frame 5 supports the suction tube 2 upward, freeing the user's hands. The tube head of the suction tube 2 extends into the box 3 to suck up the material. When sucking up the material, the suction tube 2 can be pushed left and right. The support frame 5 begins to move at the top of the box 3. The rollers 12 on the support frame 5 begin to rotate along the top of the box 3, making the movement of the support frame 5 more effortless. The suction tube 2, which moves left and right, can more comprehensively suck up the material in the box 3.

[0031] When the suction pipe 2 is moved back and forth, the limiting block 10 is pulled, so that the telescopic rod 7 extends out of the relief hole 6. The limiting block 10 moves away from the limiting groove 9, and the limiting between the support frame 5 and the fixing ring 4 is released. The fixing ring 4 can then drive the suction pipe 2 to slide back and forth on the support frame 5, so that the suction pipe 2 can slide on the support frame 5 at any time. When sliding is not required, the limiting block 10 is pushed back into the corresponding limiting groove 9, so that the pressing block presses against the limiting groove 9, and the fixing ring 4 is fixed on the support frame 5.
