Description

Technical Field

[0001] This utility model relates to the field of feeder technology, and more specifically, to a regenerated pellet feeder with an adjustable port. Background Technology

[0002] In the production process of plastic granulation extruders, the feeder plays a crucial role. It is responsible for conveying the raw materials evenly and stably into the extruder for processing. Traditional plastic granulation extruders are generally equipped with a single feeder, and the feeder usually adopts a screw conveyor method to push the raw materials in the hopper through the extrusion port to the downstream equipment.

[0003] However, in actual use, traditional feeders can only feed one type of raw material. When multiple raw materials need to be added, the feeder needs to be changed frequently. This causes the extruder to overfeed, which in turn causes the raw material to foam. Consequently, the size and weight of the crushed raw material are inconsistent, resulting in uneven mixing and poor mixing quality. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a recycled pellet feeder with an adjustable port to solve the problem that in the prior art, when multiple raw materials need to be added, a single feed hopper requires frequent feeder changes, which causes the extruder to overfeed, resulting in foaming of the raw materials, and thus uneven mixing and poor mixing quality due to inconsistent size and weight of the crushed raw materials.

[0005] To solve the above technical problems, this utility model provides the following technical solution: a recycled pellet feeder with an adjustable opening, comprising two mounting frames, which are respectively fixedly connected to the left and right sides of the top end of an extruder barrel. A placement groove is formed inside the top end of each mounting frame, and a placement frame is slidably connected inside the placement groove. A feed hopper is fixedly connected to the top end of each placement frame. Two connecting blocks are fixedly connected to the front and rear sides of the feed hopper. Support plates are hinged to the front and rear sides of the top end of each mounting frame. The connecting blocks are slidably connected to the inner wall of the support plates. Multiple slots are formed inside the support plates, and locking blocks are engaged inside the slots, with the locking blocks penetrating the connecting blocks. Multiple sliding grooves are formed inside the feed hopper, and connecting rods are slidably connected inside the sliding grooves. A screen is detachably connected to one end of each connecting rod.

[0006] Among them, the inner walls of the card slots on both the left and right sides are provided with mounting slots on the adjacent side, and the card blocks on both the left and right sides are fixedly connected with mounting blocks on the adjacent side. The other end of the mounting block is fixedly connected with a pull rope, and an elastic element is sleeved on the outside of the pull rope.

[0007] The mounting block has two limiting grooves inside, and multiple elastic elements are fixedly connected between the connecting rods on the upper and lower sides. The end of the connecting rod away from the screen is rotatably connected to the limiting block.

[0008] The mounting block is slidably connected inside the mounting groove, the pull rope is slidably connected inside the mounting groove, and a pull ring is fixedly connected to the end of the pull rope away from the mounting block.

[0009] One end of the elastic element is fixedly connected to the inner wall of the mounting groove, and the other end of the elastic element is fixedly connected to the mounting block.

[0010] The connecting rod is movably connected inside the support plate, and the side of the connecting rod away from the screen is slidably connected to the outside of the mounting block.

[0011] The limiting block is a "T" shaped block structure, and the limiting block is slidably connected inside the limiting groove.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] In the above solution, the feed hopper is supported by a support plate and the connecting block outside the feed hopper is engaged with a locking block, which allows the feed hopper to be conveniently installed on both sides of the extruder barrel. As needed, a suitable feed hopper can be installed, and the feed hopper can be adjusted to add various raw materials into the extruder barrel. This not only makes the use more flexible, but also makes the mixing quality better. Attached Figure Description

[0024] To make the technical problems, technical solutions and advantages of this utility model clearer, a detailed description will be given below in conjunction with the accompanying drawings and specific embodiments.

[0025] Example 1: Please refer to Figures 1 to 8 This utility model provides a technical solution: a recycled pellet feeder with an adjustable opening, comprising two mounting frames 2, which are respectively fixedly connected to the left and right sides of the top end of an extruder barrel 1. The lower openings of the two mounting frames 2 are of different sizes, allowing for the feeding of different raw materials. A placement groove 3 is provided inside the top end of each mounting frame 2, and a placement frame 4 is slidably connected inside the placement groove 3, providing installation space for the placement frame 4. A feed hopper 5 is fixedly connected to the top end of the placement frame 4, allowing the feed hopper 5 to be installed on the mounting frame 2. Two connecting blocks 9 are fixedly connected to the front and rear sides of the feed hopper 5. Support plates 6 are hinged to the front and rear sides of the top end of the mounting frame 2, and the connecting blocks 9 are slidably connected to the inner wall of the support plates 6, connecting the support plates 6 and the connecting blocks 9. Multiple slots 7 are provided inside the support plates 6, and locking blocks 8 are engaged inside the slots 7, with the locking blocks 8 penetrating the connecting blocks 9, thereby allowing... The support plate 6 is connected to the connecting block 9, which allows the support plate 6 to support the feed hopper 5 and limit its movement. When the feed hopper 5 is not in use, the support plate 6 can be closed, thus covering the upper side of the mounting frame 2 and preventing external dust and other impurities from entering the extruder barrel 1. The support plate 6 achieves a multi-purpose effect. The feed hopper 5 has multiple sliding grooves 19 inside, and a connecting rod 16 is slidably connected inside the sliding grooves 19. The sliding grooves 19 limit the movement of the connecting rod 16, allowing it to slide smoothly. One end of the connecting rod 16 is detachably connected to a screen 10. The connecting block 9 and the screen 10 can be installed with bolts, which is known in the prior art and will not be described in detail here. The screen 10 is used to agitate and screen the raw material entering the feed hopper 5, so that the raw material enters the extruder barrel 1 evenly.

[0026] When the feed hopper 5 is needed, the support plate 6 is opened, and the placement frame 4 is slid into the placement groove 3, so that the bottom end of the feed hopper 5 is in contact with the top end of the mounting frame 2. Then, by rotating the support plate 6 in the opposite direction, the inner side of the support plate 6 is in contact with the outer side of the feed hopper 5, and the connecting block 9 is slid into the interior of the support plate 6. Subsequently, the slot 7 is moved towards the slot block 8, so that the slot 7 passes through the interior of the connecting block 9 and engages with the slot block 8, thereby limiting the position of the connecting block 9. This, in turn, ensures that the placement frame 4 and the support plate... Under the combined action of 6, the feed hopper 5 can be limited, making it easy to install. The required model of feed hopper 5 can be selected according to the size of the raw material, thereby achieving the effect of adjustable discharge port. This allows the feed hopper 5 to add a variety of raw materials into the extruder barrel 1, which not only makes the use more flexible, but also makes the mixing quality better. When the raw material enters the interior of the feed hopper 5, it impacts the screen 10, causing the screen 10 to shake, thereby agitating and screening the raw material, resulting in higher uniformity of discharge.

[0027] Example 2: Based on Example 1, in order to facilitate the pulling of the locking block 8, an installation groove 11 is provided on the inner wall of the left and right locking slots 7 on the side close to each other. An installation block 12 is fixedly connected to the side close to each other on the left and right locking blocks 8. The installation block 12 is used to pull the locking block 8 to move. The installation block 12 is slidably connected inside the installation groove 11. The installation groove 11 limits the installation block 12 so that the installation block 12 will not deviate when sliding. The other end of the installation block 12 is fixedly connected to a pull rope 13. The pull rope 13 is slidably connected inside the installation groove 11. The installation groove 11 limits the pull rope 13 so that the pull rope 13 can slide smoothly. The end of the pull rope 13 away from the installation block 12 is fixedly connected to a pull ring. By pulling the pull ring, the two pull ropes 13 can be pulled to move. An elastic element 14 is sleeved on the outside of the pull rope 13. One end of the elastic element 14 is fixedly connected to the inner wall of the installation groove 11, and the other end of the elastic element 14 is fixedly connected to the installation block 12.

[0028] When it is necessary to pull the locking block 8, by pulling the pull ring, one end of the pull rope 13 is pulled to move the mounting block 12 away from the locking block 8. This causes the mounting block 12 to deform while compressing the elastic element 14, thereby causing the locking block 8 to disengage from the inside of the slot 7. Conversely, by releasing the pull ring, the elastic element 14 is reset, which in turn pushes the mounting block 12 to move outward, allowing the mounting block 12 to push the locking block 8 through the connecting block 9 and engage with the inside of the slot 7.

[0029] Example 3: Based on Example 2, in order to improve the screening effect of the screen 10 on the raw materials inside the feed hopper 5, two limiting grooves 15 are opened inside the mounting block 12. Multiple elastic elements 18 are fixedly connected between the upper and lower connecting rods 16. When the upper and lower screens 10 move, the connecting rods 16 can drive the elastic elements 18 to deform. When the elastic elements 18 return to their original position, the connecting rods 16 can push the screen 10 to move in the opposite direction, thereby causing the screen 10 to oscillate up and down, thus improving the screening effect on the raw materials. The connecting rods 16 are movably connected to the support plate. Inside the support plate 6, the support plate 6 provides space for the connecting rod 16 to move, so that it will not deviate when it shakes up and down or moves with the mounting block 12. The side of the connecting rod 16 away from the screen 10 is slidably connected to the outside of the mounting block 12, and the end of the connecting rod 16 away from the screen 10 is rotatably connected to the limiting block 17, so that when the support plate 6 is in contact with the feed hopper 5, the connecting rod 16 can slide into the interior of the slide groove 19. The limiting block 17 is a "T" shaped block structure, and the limiting block 17 is slidably connected to the interior of the limiting groove 15, so that the connecting rod 16 will not detach from the interior of the mounting block 12, thereby allowing the connecting rod 16 to move with the mounting block 12.

[0030] The working process of this utility model is as follows:

[0031] When other types of raw materials need to be added, the support plate 6 is opened and the placement frame 4 is slid into the placement groove 3, so that the bottom end of the feed hopper 5 is in contact with the top end of the mounting frame 2. Then, by pulling the pull ring, one end of the pull rope 13 is pulled to move the mounting block 12 away from the locking block 8. As the mounting block 12 deforms by compressing the elastic element 14, it causes the locking block 8 to disengage from the inside of the slot 7. Then, by rotating the support plate 6 in the opposite direction, the inner side of the support plate 6 is in contact with the outer side of the feed hopper 5, and the connecting block 9 is slid into the inside of the support plate 6. At this time, by releasing the pull ring, the elastic element 14 is reset, which pushes the mounting block 12 to move outward. This pushes the locking block 8 through the connecting block 9 and into the slot 7, thus limiting the connection block 9. The placement frame 4 and the support plate 6 work together to limit the feeding hopper 5, making it easy to install. The required model of feeding hopper 5 can be selected according to the material size, thus achieving an adjustable discharge port. This allows the feeding hopper 5 to add various materials to the inside of the extruder barrel 1, increasing its flexibility and improving mixing quality. The screen 10 is then installed on the connecting rod 16. When the material enters the feeding hopper 5, it impacts the screen 10, causing it to shake and the connecting rod 16 to compress the elastic element 18, causing deformation. When the elastic element 18 returns to its original position, the connecting rod 16 pushes the screen 10 in the opposite direction, causing it to shake up and down, improving the material screening effect and resulting in more uniform material feeding.
