Description

Technical Field

[0001] This utility model relates to the field of extruder technology, and in particular to a feeder for a plastic granulation extruder. Background Technology

[0002] A plastic granulation extruder is a device that processes plastic raw materials into granules. First, the recycled raw materials are crushed by a crusher. After crushing, the PVC in the raw materials is crushed into PVC granules. The crushed raw materials are sent to a blower through a closed conveying pipe to separate impurities and granules. The artificial leather granules separated from the blower outlet are packaged in woven bags. These PVC granules are then fed into the extruder barrel and mixed with materials such as stone powder. After being extruded and granulated through the die at the end of the barrel, the final product is plastic granules of uniform size after drying and screening. It can continuously produce a large number of plastic granules, providing high-quality raw materials for the production of various plastic products.

[0003] PVC granules and other materials need to enter the extruder barrel through a hopper. Generally, workers manually feed the raw materials directly into the hopper, which is laborious and inconvenient to adjust the outflow. Existing feeding mechanisms, such as CN220242071U, require that motors 1, 2, 3, and the electromagnetic transmitter be connected to external power sources and the on-board electrical control box to adjust the outflow of nylon plastic granules and prevent them from clogging the extruder. This results in too many electrical devices and waste. Therefore, this application provides a feeder for a plastic granulation extruder to meet the requirements. Utility Model Content

[0004] The technical problem this utility model aims to solve is to provide a feeder for a plastic granulation extruder to address the issue that existing PVC granules and other materials need to enter the extruder barrel through a hopper. Generally, workers manually feed the raw materials directly into the hopper, which is laborious and inconvenient to adjust the outflow. In existing feeding mechanisms such as CN220242071U, in order to adjust the outflow of nylon plastic granules from the feeding body and prevent the nylon plastic granules from clogging the extruder, it is necessary to connect motor one, motor two, motor three, electromagnetic transmitter, and other equipment to external power sources and the electrical control box on the equipment, resulting in too many electrical devices and causing waste.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0006] A feeder for a plastic granulation extruder includes two mounting frames with a quick-connect mechanism installed between them. The quick-connect mechanism includes a slider on each mounting frame, each slider having a through groove. The slider is slidably connected to the mounting frame via the through groove. A fixed ring is fixedly connected to the bottom of each slider, and a feeding adjustment mechanism for controlling the feeding amount is installed inside the fixed ring. A telescopic rod is fixedly connected to the top of each slider. A fixed knob is provided on both the slider and the telescopic rod. A fixed frame is fixedly connected to the top of the telescopic rod. A feeding mechanism for assisting feeding is provided on one side of the fixed frame. The feeding mechanism includes a rotating block rotatably connected to one side of the fixed frame. A sliding groove is provided at the bottom of the rotating block, and a sliding frame is slidably connected inside the sliding groove. A drum is rotatably connected to the middle of the sliding frame, and a connecting rope is stored on the drum. One end of the connecting rope is away from the drum and fixedly connected to a hook. A motor for driving the drum to rotate is installed on one side of the sliding frame.

[0007] Preferably, a hydraulic cylinder is fixedly connected to the top of the mounting frame near the rotating block, and the output end of the hydraulic cylinder is fixedly connected to the same second mounting frame. The end of the rotating block away from the first mounting frame abuts against the top of the second mounting frame.

[0008] Preferably, the feeding adjustment mechanism includes a hopper supported by the fixed ring, a feeding pipe connected to each other at the bottom of the hopper, a switch handle for controlling whether to feed material on the feeding pipe, a stop block 1 fixedly connected to the top inner wall of the hopper, the stop block 1 having multiple feeding ports of different sizes and numbers, a sliding groove 1 at the top of the hopper, a ring block fitted onto the hopper through the sliding groove, a stop block 2 fixedly connected to the bottom inner wall of the ring block, and a feeding groove on the stop block 2.

[0009] Preferably, a fixing fork capable of puncturing the packaging bag is fixedly connected to the bottom of one end of the rotating block near the fixing frame.

[0010] Preferably, the top of the second fixing frame is fixedly connected to two limiting blocks, and the end of the rotating block away from the first fixing frame is located between the limiting blocks.

[0011] Preferably, a bracket is fixedly connected to the top of the mounting bracket below the rotating block, and a guide frame is fixedly connected between the brackets.

[0012] Compared with the prior art, this utility model has at least the following beneficial effects:

[0013] In the above solution, by setting up a quick-release mechanism, when the feeding adjustment mechanism needs cleaning, the fixing knob on slider one and telescopic rod can be turned to release the fixing effect of slider one and telescopic rod. Then, slider one, together with telescopic rod and fixing frame one, can be slid to a suitable position, and fixing frame one can be lifted up to a suitable position. This allows the feeding adjustment mechanism to be lifted and disassembled from the inside of the fixing ring for cleaning. This prevents material from adhering to the inside of the feeding adjustment mechanism due to long-term use, which could cause mixing with other materials when they are added.

[0014] By setting up a feeding mechanism, when feeding is required, the packaging bag containing the raw material is placed on the ground between the mounting frames. The hook on the connecting rope is hung on the packaging bag placed on the ground. The motor is started, and the drum rotates, pulling the connecting rope and the packaging bag on the hook upward. When the packaging bag is pulled to the highest point, the hydraulic cylinder is activated, and the output end of the hydraulic cylinder drives the second fixed frame to rise upward. This also drives one end of the rotating block to rise and rotate between the limit blocks. During the lifting, since the second fixed frame is higher than the first fixed frame, the sliding frame will slide towards the first fixed frame in the sliding groove at the bottom of the rotating block under the influence of gravity. This will cause the packaging bag on the hook to slide together. When it slides to the lowest point, the packaging bag on the hook will be stuck on the fixed fork, causing the packaging bag to break. The raw material inside the packaging bag will fall directly into the feeding adjustment mechanism, completing the feeding. The advantage of this method is that the gravity effect of the height difference drives the movement and feeding of the packaging bag, eliminating the need for manual handling of raw materials and saving physical labor.

[0015] By setting up a feeding adjustment mechanism, when the raw material is fed into the ring block, it will fall down along the feeding groove on the second stop block, and then fall into the inside of the feed hopper through the feeding port on the first stop block. Finally, it will flow out from the feeding pipe at the bottom of the hopper and enter the inside of the extruder. When it is necessary to adjust the outflow, the ring block can be rotated directly from the outside, allowing the ring block to rotate inside the first chute. When the ring block rotates, it will drive the second stop block to rotate, moving the feeding groove on the second stop block above the feeding ports of other sizes, so that the raw material can fall through the feeding ports of different sizes. The advantage of this is that the outflow can be adjusted by directly rotating the ring block, without setting up too many electrical devices, thus avoiding waste. By setting up a guide frame, it is possible to prevent the raw material from falling outside the ring block during the feeding process, thus improving the feeding. Attached Figure Description

[0029] like Figure 1 , Figure 3 and Figure 4As shown, an embodiment of this utility model provides a feeder for a plastic granulation extruder, including two mounting frames 1. A quick-connect mechanism 2 is installed between the mounting frames 1. The quick-connect mechanism 2 includes a slider 21, which is provided on each mounting frame 1. A through groove 22 is provided on the slider 21, and the slider 21 is slidably connected to the mounting frame 1 through the through groove 22. The bottom of the slider 21 is fixedly connected to the same fixing ring 23. A feeding adjustment mechanism 3 that can control the feeding amount is installed inside the fixing ring 23. A telescopic rod 24 is fixedly connected to the top of each slider 21. A fixing knob 26 is provided on both the slider 21 and the telescopic rod 24. The top of the telescopic rod 24 is fixedly connected to the same fixing frame 25. A feeding mechanism 4 that can help feed material is provided on one side of the fixing frame 25. The feeding mechanism 4 includes a component that is rotatably connected to one side of the fixing frame 25. The rotating block 41 has a sliding groove 42 at its bottom. A sliding frame 43 is slidably connected inside the sliding groove 42. A drum 44 is rotatably connected in the middle of the sliding frame 43. A connecting rope 45 is stored on the drum 44. One end of the connecting rope 45 is away from the drum 44 and is fixedly connected to a hook 46. A motor 47 that can drive the drum 44 to rotate is installed on one side of the sliding frame 43. A hydraulic cylinder 5 is fixedly connected to the top of the mounting frame 1 near the rotating block 41. The output end of the hydraulic cylinder 5 is fixedly connected to the same fixing frame 25. The end of the rotating block 41 away from the fixing frame 25 abuts against the top of the fixing frame 26. A fixing fork 10 that can puncture the packaging bag is fixedly connected to the bottom of the end of the rotating block 41 near the fixing frame 25. Two limiting blocks 9 are fixedly connected to the top of the fixing frame 26. The end of the rotating block 41 away from the fixing frame 25 is located between the limiting blocks 9.

[0030] By setting up the quick-release mechanism 2, when the feeding adjustment mechanism 3 needs cleaning, the fixing knob 26 on the slider 21 and telescopic rod 24 can be turned to release the fixing effect of the slider 21 and telescopic rod 24. Then, the slider 21, together with the telescopic rod 24 and the fixing frame 25, can be slid to a suitable position, and the fixing frame 25 can be lifted up to a suitable position. This allows the feeding adjustment mechanism 3 to be lifted and disassembled from the inside of the fixing ring 23 for cleaning. This prevents the material from adhering inside the feeding adjustment mechanism 3 due to long-term use, which could cause mixing with other materials when they are added.

[0031] By setting up the feeding mechanism 4, when feeding is required, the packaging bag containing the raw materials is placed on the ground between the mounting frames 1, and the hook 46 on the connecting rope 45 is hung on the packaging bag placed on the ground. The motor 47 is started, and the drum 44 rotates, pulling the packaging bag on the connecting rope 45 and the hook 46 upward. When the packaging bag is pulled to the highest point, the hydraulic cylinder 5 is started, and the output end of the hydraulic cylinder 5 drives the fixed frame 2 6 to rise upward, driving one end of the rotating block 41 to also rise and rotate upward between the limit blocks 9. During the lifting, because the fixed frame 2 6 is higher than the fixed frame 1, the fixed frame 2 6 will be lifted upward. Under the influence of gravity, the sliding frame 43 will slide towards the fixed frame 25 in the sliding groove 42 at the bottom of the rotating block 41, causing the packaging bag on the hook 46 to slide together. When it slides to the lowest point, the packaging bag on the hook 46 will be stuck on the fixed fork 10, causing the packaging bag to break. The raw material inside the packaging bag will fall directly into the feeding adjustment mechanism 3, completing the feeding. The advantage of this is that the gravity of the height difference will drive the packaging bag to move and feed, eliminating the need for manual handling to feed the raw material, thus saving physical strength.

[0032] like Figure 1 and Figure 2 As shown, the feeding adjustment mechanism 3 includes a hopper 31 supported by a fixing ring 23. The bottom of the hopper 31 is fixedly connected to a feeding pipe 35 that is interconnected. A switch handle 36 for controlling whether to feed is installed on the feeding pipe 35. A stop block 32 is fixedly connected to the top inner wall of the hopper 31. Multiple feeding ports 33 of different sizes and quantities are opened on the stop block 32. A sliding groove 34 is opened on the top of the hopper 31. A ring block 37 is fitted onto the hopper 31 through the sliding groove 34. A stop block 38 is fixedly connected to the bottom inner wall of the ring block 37. A feeding groove 39 is opened on the stop block 38. A bracket 7 is fixedly connected to the top of the mounting frame 1 below the rotating block 41. A guide frame 8 is fixedly connected between the brackets 7.

[0033] By setting the feeding adjustment mechanism 3, when the raw material is fed into the ring block 37, it will fall down along the feeding groove 39 on the second stop block 38, and then fall into the inside of the feed hopper 31 through the feeding port 33 on the first stop block 32. Finally, it will flow out from the feeding pipe 35 at the bottom of the hopper 31 and enter the inside of the extruder. When it is necessary to adjust the outflow, the ring block 37 can be rotated directly from the outside, so that the ring block 37 rotates inside the first chute 34. When the ring block 37 rotates, it will drive the second stop block 38 to rotate, so that the feeding groove 39 on the second stop block 38 moves above the feeding port 33 of other sizes, so that the raw material can fall through the feeding port 33 of different sizes. The advantage of this is that the outflow can be adjusted by directly rotating the ring block 37, without setting up too many electrical devices, thus avoiding waste. By setting the guide frame 8, it is possible to prevent the raw material from falling outside the ring block 37 during the process of being fed into the ring block 37, so as to improve the feeding.

[0034] The technical solution provided by this utility model, by setting up a quick-release mechanism 2, allows the material feeding adjustment mechanism 3 to be cleaned when the fixing knob 26 on the slider 21 and telescopic rod 24 is turned to release the fixing effect of the slider 21 and telescopic rod 24. Then, the slider 21, together with the telescopic rod 24 and the fixing frame 25, is slid to a suitable position, and the fixing frame 25 is lifted upward to a suitable position. This allows the material feeding adjustment mechanism 3 to be lifted and disassembled from the inside of the fixing ring 23 for cleaning. This prevents the material feeding adjustment mechanism 3 from being mixed with other materials when they are added due to the adhesion of some materials inside the material feeding adjustment mechanism 3 caused by long-term use.

[0035] By setting up the feeding mechanism 4, when feeding is required, the packaging bag containing the raw materials is placed on the ground between the mounting frames 1, and the hook 46 on the connecting rope 45 is hung on the packaging bag placed on the ground. The motor 47 is started, and the drum 44 rotates, pulling the packaging bag on the connecting rope 45 and the hook 46 upward. When the packaging bag is pulled to the highest point, the hydraulic cylinder 5 is started, and the output end of the hydraulic cylinder 5 drives the fixed frame 2 6 to rise upward, driving one end of the rotating block 41 to also rise and rotate upward between the limit blocks 9. During the lifting, because the fixed frame 2 6 is higher than the fixed frame 1, the fixed frame 2 6 will be lifted upward. Under the influence of gravity, the sliding frame 43 will slide towards the fixed frame 25 in the sliding groove 42 at the bottom of the rotating block 41, causing the packaging bag on the hook 46 to slide together. When it slides to the lowest point, the packaging bag on the hook 46 will be stuck on the fixed fork 10, causing the packaging bag to break. The raw material inside the packaging bag will fall directly into the feeding adjustment mechanism 3, completing the feeding. The advantage of this is that the gravity of the height difference will drive the packaging bag to move and feed, eliminating the need for manual handling to feed the raw material, thus saving physical strength.

[0036] By setting the feeding adjustment mechanism 3, when the raw material is fed into the ring block 37, it will fall down along the feeding groove 39 on the second stop block 38, and then fall into the inside of the feed hopper 31 through the feeding port 33 on the first stop block 32. Finally, it will flow out from the feeding pipe 35 at the bottom of the hopper 31 and enter the inside of the extruder. When it is necessary to adjust the outflow, the ring block 37 can be rotated directly from the outside, so that the ring block 37 rotates inside the first chute 34. When the ring block 37 rotates, it will drive the second stop block 38 to rotate, so that the feeding groove 39 on the second stop block 38 moves above the feeding port 33 of other sizes, so that the raw material can fall through the feeding port 33 of different sizes. The advantage of this is that the outflow can be adjusted by directly rotating the ring block 37, without setting up too many electrical devices, thus avoiding waste. By setting the guide frame 8, it is possible to prevent the raw material from falling outside the ring block 37 during the process of being fed into the ring block 37, so as to improve the feeding.
