Description

Technical Field

[0001] This utility model relates to the field of injection molding machines, specifically a feeding device for high-speed injection molding machines. Background Technology

[0002] Injection molding machines, also known as injection molding machines or injection machines, are the main molding equipment that uses plastic molds to make plastic products of various shapes from thermoplastic or thermosetting plastics. They are divided into vertical, horizontal, and all-electric types. Injection molding machines can heat plastics and apply high pressure to molten plastics, causing them to be injected and fill the mold cavity.

[0003] Traditional injection molding machines use a feeding device to directly feed crushed plastic into the machine. Because the crushed plastic is irregularly shaped and varies in size, large pieces can cause the screw to jam when they enter the barrel. This not only damages the injection molding machine but also prevents the device from feeding, requiring manual unclogging before it can be used again, ultimately leading to decreased production efficiency. Therefore, a new technical solution is needed to address this issue. Utility Model Content

This solves the technical problem that current feeding devices for injection molding machines directly put crushed plastic into the device. Because the crushed plastic is irregular in shape and varies in size, when there are large plastic pieces, entering the barrel will cause the screw to jam. This not only damages the injection molding machine but also prevents the device from feeding, requiring the machine to be stopped and manually cleared before it can be used again, ultimately leading to a decrease in production efficiency.

[0005] To achieve the purpose of this utility model, the technical solution adopted by this utility model is as follows: design a material feeding device for a high-speed injection molding machine, including a material box, wherein a material feeding hole is opened at the bottom end of the material box, and further comprising;

[0006] The filtering mechanism includes first guide plates installed on both sides of the inner cavity of the material box. Both first guide plates are inclined. A filter tube is connected between the two first guide plates. A drive roller is installed inside the filter tube. Multiple actuating plates are installed on the outside of the drive roller.

[0007] The crushing mechanism includes a connecting plate installed at one end of the drive roller, a plurality of connecting shafts rotatably connected to the connecting plate, the plurality of connecting shafts being staggered with a plurality of actuating plates, and crushing blades being installed on the outer side of each of the plurality of connecting shafts; a transmission mechanism is provided between the end of the connecting shaft away from the connecting plate and the material box.

[0008] The drive mechanism is used to drive the rotation of the drive roller.

[0009] Preferably, the transmission mechanism includes a first gear mounted on the end of the connecting shaft away from the connecting disc and a second gear mounted on the inner wall of the material box near the end of the first gear. The first gear meshes with the second gear. The actuating plate has a notch at the end near the first gear, and the second gear is placed in the notch. The size of the second gear is smaller than the size of the notch.

[0010] Preferably, the driving mechanism includes a driving motor disposed at one end of the outer side of the material box, a connecting frame is installed at the end of the material box near the driving motor, the driving motor is mounted on the connecting frame, the driving end of the driving motor is connected to a driving shaft through a coupling, and the driving shaft rotates through the material box and is connected to the driving roller.

[0015] Preferably, the center of the drive roller and the center of the arc-shaped tube are on the same horizontal line, and the end of the actuating plate away from the drive roller moves against the inner wall of the filter tube.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] 1. This utility model combines a drive motor, drive roller, actuating plate, first guide plate, filter tube, connecting shaft, crushing blade, first gear, second gear, and notch. The drive motor drives the drive roller to rotate, which in turn actuates the plastic through the filter tube. Plastic granules that meet the specifications pass through the filter tube and then enter the injection molding machine through the feeding hole. Larger plastic granules are placed in the filter tube. When the drive roller rotates, the first and second gears mesh, causing the connecting shaft and crushing blade to rotate. The rotation of the crushing blade can crush large plastic granules during the filtration process. The plastic granules are then filtered through the filter tube, ensuring the uniformity of the size of the plastic granules fed. This prevents large plastic granules from jamming the screw or blocking the feeding device, thus improving the feeding efficiency.

[0018] 2. This utility model combines a drive sprocket, a driven sprocket, a chain, a transmission shaft, a stirring plate, a rotating shaft, and a drive shaft. When filtering particles, the stirring plate can rotate with the drive roller due to the arrangement of the drive sprocket, driven sprocket, and chain. This allows the stirring plate to stir within the discharge hole, thereby preventing plastic particles from accumulating and causing blockage. Attached Figure Description

[0025] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0026] Example 1: A feeding device for a high-speed injection molding machine, see [link / reference] Figures 1 to 5 The system includes a material bin 1, with a discharge hole 51 at the bottom end, and a filtration mechanism. The filtration mechanism includes two first guide plates 2 installed on both sides of the inner cavity of the material bin 1, both first guide plates 2 being inclined. A filter tube 21 is connected between the two first guide plates 2, and a drive roller 22 is installed inside the filter tube 21. Multiple actuating plates 23 are installed on the outer side of the drive roller 22. The two first guide plates 2 are arranged in an inverted V-shape. The filter tube 21 is arc-shaped, and the two first guide plates 2 are respectively connected to both sides of the filter tube 21. A crushing mechanism 4 includes a connecting disc 41 installed at one end of the drive roller 22. Multiple connecting shafts 42 are rotatably connected to the connecting disc 41. The multiple connecting shafts 42 are staggered with the multiple actuating plates 23, and crushing blades 43 are installed on the outer side of each of the multiple connecting shafts 42. The connecting shafts 42 are located away from the drive roller 22. A transmission mechanism is provided between one end of the receiving plate 41 and the material box 1. The transmission mechanism includes a first gear 45 installed on the end of the connecting shaft 42 away from the connecting plate 41 and a second gear 44 installed on the inner wall of the material box 1 near the end of the first gear 45. The first gear 45 and the second gear 44 mesh. The actuating plate 23 has a notch 46 at the end near the first gear 45. The second gear 44 is placed in the notch 46, and the size of the second gear 44 is smaller than the size of the notch 46. A driving mechanism is used to drive the rotation of the driving roller 22. The driving mechanism includes a driving motor 31 installed at one end of the outer side of the material box 1. A connecting frame 3 is installed at the end of the material box 1 near the driving motor 31. The driving motor 31 is installed on the connecting frame 3. The driving end of the driving motor 31 is connected to the driving shaft 32 through a coupling. The driving shaft 32 rotates through the material box 1 and is connected to the driving roller 22.

[0027] During operation, the discharge port 51 of the material bin 1 is connected to the feed port of the injection molding machine. Plastic granules are then added into the material bin 1 and guided into the filter tube 21 by the first guide plate 2. The drive motor 31 is then started to drive the drive roller 22 to rotate, thereby actuating the plate 23 to move the plastic through the filter tube 21 for filtration. Plastic granules that meet the specifications pass through the filter tube 21 and enter the injection molding machine through the discharge port 51. Larger plastic granules are placed in the filter tube 21. When the drive roller 22 rotates, the first gear 45 and the second gear 44 mesh, causing the connecting shaft 42 and the crushing blade 43 to rotate. The rotation of the crushing blade 43 can crush the large plastic granules during the filtration process. The plastic granules are then filtered through the filter tube 21 until the large plastic granules meet the specifications and are discharged. This ensures the uniformity of the size of the plastic granules fed and avoids large plastic granules causing the screw to jam or the discharge device to become blocked, thus improving the discharge efficiency.

[0028] For details, see Figure 1 and Figure 3 A rotating shaft 52 is rotatably connected between the two sides of the inner cavity of the discharge hole 51. Multiple stirring plates 53 are installed on the outer side of the rotating shaft 52. A transmission shaft 35 is rotatably connected to the end of the material box 1 near the drive motor 31. One end of the transmission shaft 35 rotatably passes through the material box 1 and is connected to the rotating shaft 52. A driven sprocket 36 is installed on the outer side of the transmission shaft 35. A driving sprocket 34 is installed on the outer side of the drive shaft 32. A chain 33 connects the driving sprocket 34 and the driven sprocket 36. When filtering particles, the stirring plates 53 can rotate with the rotation of the drive roller 22 through the arrangement of the driving sprocket 34, the driven sprocket 36 and the chain 33. Thus, the stirring plates 53 are stirred in the discharge hole 51, thereby avoiding the accumulation of plastic particles in the discharge hole 51 and causing blockage.

[0029] Further, see Figure 2 Each of the two guide plates is equipped with a second guide plate 5 on the material box 1 below the two guide plates. The lowest ends of the two second guide plates 5 are respectively placed on both sides of the discharge hole 51. The setting of the second guide plates 5 facilitates the guidance of the filtered plastic particles to the discharge hole 51, which further facilitates the discharge of the plastic particles through the discharge hole 51.

[0030] It is worth noting that, see Figure 2The center of the drive roller 22 is on the same horizontal line as the center of the arc tube. The end of the actuating plate 23 away from the drive roller 22 moves against the inner wall of the filter tube 21. This is to ensure that the actuating plate 23 always moves against the inner wall of the filter tube 21 during the rotation of the actuating plate 23. This ensures that the rotation of the actuating plate 23 can move large plastic particles stuck inside the filter tube 21, and avoid large plastic particles accumulating inside the filter tube 21 and causing blockage, which would affect the filtration of plastic particles.
