Description

Technical Field

[0001] This application relates to the technical field of injection molding, and in particular to a feeding platform for an injection molding machine production line. Background Technology

[0002] Injection molding machines are core mass production equipment for metal products. They mainly work by melting metallurgical powders or granular raw materials and injecting them under high pressure into a mold cavity, where they are then cooled and solidified. This process allows for the mass production of metal parts of various specifications, and they are widely used in precision manufacturing, daily necessities, auto parts, and many other industrial fields. To improve the efficiency of large-scale production, existing injection molding workshops generally adopt a multi-machine parallel layout, with multiple injection molding machines operating simultaneously to process parts of different specifications and types.

[0003] Due to differences in the molding processes of different parts, the types and proportions of raw materials required by each injection molding machine vary, placing high demands on the accuracy and stability of material feeding. Currently, material feeding operations mostly rely on manual feeding or using a crane to lift the entire raw material to the injection molding machine's feed hopper for feeding.

[0004] However, manual and crane-based material feeding methods are cumbersome, time-consuming, and inefficient, potentially limiting overall production line capacity. Furthermore, these methods involve working at heights, increasing the risk of material falling and personnel collisions, posing significant safety hazards. Therefore, further improvements and optimizations are needed. Summary of the Invention

[0005] To improve the feeding efficiency of injection molding machines, this application provides a feeding platform for an injection molding machine production line.

[0006] The feeding platform of the injection molding machine production line provided in this application adopts the following technical solution: A feeding platform for an injection molding machine production line includes an elevated platform and a feeding conduit. Multiple storage bins are arranged at intervals on the elevated platform, and multiple injection molding machines are arranged at the bottom of the elevated platform. The feeding conduit is set in a corresponding manner to the number of injection molding machines. One end of the feeding conduit is connected to the elevated platform, and the other end is connected to the feed hopper of the corresponding injection molding machine.

[0007] By adopting the above technical solution, multiple storage bins are used to store different types or proportions of raw materials. The storage bins are erected on top of the injection molding machine via an elevated platform. When the injection molding machine at the bottom of the elevated platform needs to be fed, the raw materials in the storage bins are sent into the feeding conduit. Under the action of gravity, the raw materials slide precisely into the feed hopper of the corresponding injection molding machine through the feeding conduit, avoiding the use of manual or crane feeding methods and greatly improving the feeding efficiency of the injection molding machine.

[0008] Optionally, the bottom of the storage hopper is connected to a discharge pipe, and the storage hopper is provided with a first opening and closing component for opening and closing the discharge pipe; the number of storage hoppers and the number of feeding conduits are correspondingly set, and the discharge pipe of each storage hopper is connected to the corresponding feeding conduit.

[0009] By adopting the above technical solution, the raw materials used in the injection molding machine are proportioned according to the molding process requirements and stored in the storage tank. When the injection molding machine needs to be fed, the discharge pipe is opened, so that the raw materials in the storage tank fall into the feeding pipe and slide down to the feed hopper of the corresponding injection molding machine, thereby realizing the feeding of the injection molding machine.

[0010] Optionally, a metering tube is connected to the bottom of the storage hopper, and the storage hopper is provided with a second opening and closing component for opening and closing the metering tube; a material picking platform is slidably installed on the elevated platform, and a metering cylinder is connected to the material picking platform. The metering cylinder is used to receive the raw materials output by the metering tube and transfer them to the feeding conduit.

[0011] By adopting the above technical solution, when the injection molding machine needs to be fed, the metering cylinder is moved to the bottom of the metering tube of the storage tank via the feeding platform and the metering tube is opened, so that the metering cylinder receives the quantitative raw material discharged from the metering tube; then the feeding platform is moved to put the raw material received by the metering cylinder into the corresponding feeding conduit of the injection molding machine, so as to achieve precise control of the amount of raw material required by the injection molding machine.

[0012] Multiple storage bins hold different types of raw materials. In practical applications, if the injection molding machine requires a mixture of two or more raw materials, the raw materials in multiple specific storage bins can be collected sequentially through a metering cylinder and mixed in the required proportions to obtain the desired mixture for the injection molding machine. This design allows the storage bins to hold a single type of raw material, eliminating the need for pre-mixing. The mixing and proportioning of raw materials is completed on-site via the material handling station, significantly reducing the overall process steps.

[0013] Optionally, the second opening and closing component includes a combined cover and a first spring. The combined cover is slidably installed inside the metering tube. The first spring is disposed between the combined cover and the storage hopper. In its normal state, the first spring forces the combined cover to open the inlet end of the metering tube and close the outlet end of the metering tube. When the combined cover moves down, it opens the outlet end of the metering tube and closes the inlet end of the metering tube.

[0014] By adopting the above technical solution, under normal conditions, the combined cover, under the action of the first spring, opens the inlet end of the metering tube and closes the outlet end, allowing the raw material in the storage tank to fill the metering tube, thus storing a certain amount of raw material. When the combined cover is driven to move downwards, it opens the inlet end of the metering tube and closes the outlet end, thereby discharging a certain amount of raw material from the metering tube into the metering cylinder. The effect achieved is that the amount of raw material received by the metering cylinder is fixed each time the combined cover moves downwards, thereby achieving precise control of the amount of raw material input required by the injection molding machine and improving the mixing accuracy of the mixture.

[0015] Optionally, the combined cover is connected to a pressure rod, and a lifting seat for pressing the pressure rod is slidably installed on the material picking platform; a rotating shaft is rotatably installed on the material picking platform, a first guide plate is provided on the rotating shaft, the outer wall of the first guide plate forms a first guide surface, and the lifting seat is provided with a first roller that abuts against the first guide surface.

[0016] By adopting the above technical solution, the metering cylinder is moved to the bottom of the storage hopper via the material handling platform. When the lifting seat moves down, the pressure rod can press the combined cover to open the metering tube and transfer the raw material in the metering tube into the metering cylinder. When the rotating shaft rotates, the lifting seat is raised and lowered by the first guide plate, improving the overall ease of operation.

[0017] Optionally, a translation frame is slidably mounted on the lifting seat, and a metering cylinder is installed at one end of the translation frame. The lifting seat presses the pressure rod through the translation frame. The material handling platform is equipped with a push-pull assembly for driving the translation frame to slide.

[0018] Optionally, the rotating shaft is provided with a second guide disk, and the outer wall of the second guide disk forms a second guide surface; the push-pull assembly includes a swing frame, a second roller and a third roller, the swing frame is hinged to the material picking platform, the second roller and the third roller are respectively disposed at both ends of the swing frame, the second roller abuts against the second guide surface, and a push-pull groove for the third roller to be inserted is opened at the end of the translation frame away from the metering cylinder.

[0019] By adopting the above technical solution, when the metering cylinder is dispensing material, the dispensing platform is moved to one side of a specific storage bin. A rotating shaft drives the first and second guide discs to rotate. The second guide surface of the second guide disc pushes the second roller of the swing frame. With the cooperation of the third roller and the push-pull slide, the translation frame is moved, allowing it to move the metering cylinder into the bottom wall of the metering tube in the storage bin. Combined with the downward movement of the lifting seat, the metering tube can be opened, allowing the raw material inside to fall into the metering cylinder, greatly improving the ease of material dispensing.

[0020] Optionally, the first guide surface includes a first arc segment and a second arc segment, the distance from the first arc segment to the center of the rotation shaft is greater than the distance from the second arc segment to the center of the rotation shaft, and when the first roller rotates into the first arc segment, the lifting seat is raised; the second guide surface includes a third arc segment and a fourth arc segment, the distance from the third arc segment to the center of the rotation shaft is greater than the distance from the fourth arc segment to the center of the rotation shaft, and when the second roller rotates into the third arc segment, the translation frame extends; when the second roller rotates into the third arc segment, the first roller moves from the first arc segment to the second arc segment; when the second roller rotates out of the third arc segment, the first roller moves from the second arc segment to the first arc segment.

[0021] By adopting the above technical solution, when the second roller rotates into the third arc segment (the swing frame drives the translation frame to extend), the metering cylinder moves into the bottom of the metering tube. At this time, as the rotating shaft rotates, the first roller moves from the first arc segment to the second arc segment, causing the lifting seat to drive the translation frame to move down. In this stage, the translation frame first extends to bring the metering cylinder into the bottom of the metering tube, and then the lifting seat drives the translation frame to move down to open the metering tube, so that the raw material in the metering tube falls into the metering cylinder.

[0022] As the rotating shaft rotates, when the second roller moves out of the third arc segment, the first roller moves from the second arc segment to the first arc segment, forcing the lifting seat to rise. The lifting seat then drives the translation frame to rise, closing the outlet end of the metering tube and completing one feeding of the metering cylinder. As the rotating shaft rotates, the second roller moves from the third arc segment to the fourth arc segment, thereby moving the metering cylinder, which has completed feeding, out of the bottom of the metering tube. This allows the feeding platform to transfer the metering cylinder to the feeding guide, improving the overall ease of operation.

[0023] Optionally, a material sliding port is formed at the bottom of the metering cylinder, and a material taking cover is slidably installed at the material sliding port. A second spring is provided between the material taking cover and the metering cylinder. The second spring normally forces the material taking cover to close the material sliding port. A feeding hopper is installed on the elevated platform, and one end of the feeding guide is connected to the feeding hopper. An abutment rod for pushing the material taking cover is connected to the elevated platform.

[0024] By adopting the above technical solution, the material taking platform is moved to one side of the feeding hopper, and then the measuring cylinder is moved above the feeding hopper by extending the translation frame. During this process, the abutment rod pushes the material taking cover plate, thereby opening the measuring cylinder, allowing the raw material received in the measuring cylinder to fall into the feeding hopper, and slide down to the injection machine through the feeding guide tube, thus improving the convenience of raw material transfer operation.

[0025] Optionally, the material receiving cover plate has an abutting portion that abuts against the abutting rod, and the surface of the abutting portion near the abutting rod is wavy.

[0026] By adopting the above technical solution, after the metering cylinder moves above the feeding hopper, the abutting rod abuts against the abutting part of the material receiving cover plate to open the metering cylinder, allowing the raw material inside the metering cylinder to slide into the feeding hopper. As the rotating shaft rotates, it drives the lifting seat to rise and fall, causing the lifting seat to move the abutting part relative to the abutting rod. The surface of the abutting part near the abutting rod is wavy, thus cooperating with the abutting rod to generate a certain amplitude of vibration, making the discharge of raw material from the metering cylinder more thorough.

[0029] The following combination Figures 1-9 This application will be described in further detail.

[0030] Example 1: This application discloses a feeding platform for an injection molding machine production line.

[0031] Reference Figure 1 , Figure 2 A feeding platform for an injection molding machine production line includes an elevated platform 1 and a feeding conduit 2. Multiple injection molding machines are arranged at intervals in the injection workshop. Each injection molding machine has a feeding hopper (the injection molding machine is existing technology equipment, and its structure will not be described in detail here, and it is not shown in the figure). The elevated platform 1 is erected on top of the multiple injection molding machines, and the top wall of the elevated platform 1 is equipped with a guardrail.

[0032] Multiple storage bins 3 are placed on the elevated platform 1, with the number of storage bins 3 corresponding to the number of injection molding machines. The storage bins 3 are arranged at intervals along the length of the elevated platform 1, and the arrangement direction of the storage bins 3 is consistent with the arrangement direction of the injection molding machines. Each storage bin 3 has a support frame 33 at its bottom, and the storage bin 3 is supported on the elevated platform 1 by the support frame 33. In this embodiment, a discharge pipe 31 is fixedly connected to the bottom of the storage bin 3. The discharge pipe 31 is vertically arranged, and its upper end connects to the interior of the storage bin 3. The storage bin 3 is provided with a first opening / closing member 4 for opening and closing the discharge pipe 31.

[0033] The first opening and closing component 4 includes a discharge cover plate 41 and a cylinder 42. The discharge cover plate 41 is slidably installed at the bottom of the discharge pipe 31. The cylinder 42 is horizontally arranged, and the cylinder body of the cylinder 42 is fixedly installed on the side wall of the support frame 33. The piston rod of the cylinder 42 is fixedly connected to the discharge cover plate 41. When the piston rod of the cylinder 42 extends outward, the discharge cover plate 41 covers the lower end of the discharge pipe 31. When the piston rod of the cylinder 42 retracts inward, the discharge cover plate 41 opens the discharge pipe 31.

[0034] The number of feeding conduits 2 corresponds to the number of injection molding machines. One end of the feeding conduit 2 is connected to the feed hopper of the corresponding injection molding machine, and the other end passes through the elevated platform 1 and is fixedly connected to the feeding hopper 21. In this embodiment, the feeding hopper 21 is located directly below the discharge pipe 31 of the corresponding storage tank 3, and the discharge pipe 31 of each storage tank 3 is connected to the corresponding feeding conduit 2 through the feeding hopper 21.

[0035] The implementation principle of Embodiment 1 of this application is as follows: Multiple storage bins 3 are used to store raw materials of different types or proportions. The storage bins 3 are mounted on top of the injection molding machine via an elevated platform 1. When the injection molding machine at the bottom of the elevated platform 1 needs to be fed, the discharge cover 41 is opened, and the raw materials in the storage bins 3 are sent into the feeding conduit 2. Under the action of gravity, the raw materials slide precisely into the feed hopper of the corresponding injection molding machine through the feeding conduit 2, avoiding the use of manual or crane feeding methods and greatly improving the feeding efficiency of the injection molding machine.

[0036] Example 2: This application discloses a feeding platform for an injection molding machine production line.

[0037] The difference between the feeding platform of the injection molding machine production line disclosed in this application and that in embodiment 1 is: Reference Figure 3 , Figure 4 , Figure 5 In this embodiment, a metering tube 32 is fixedly connected to the bottom of the storage tank 3. The metering tube 32 is vertically arranged, with its upper end connected to the interior of the storage tank 3 and forming an inlet end, and its lower end forming an outlet end. The storage tank 3 is provided with a second opening and closing component 5 for opening and closing the metering tube 32. The second opening and closing component 5 includes a combined cover 51 and a first spring 52. The combined cover 51 includes a first cover plate 512, a second cover plate 513, and a connecting rod 514. The first cover plate 512 is slidably installed at the inlet end of the metering tube 32, and the second cover plate 513 is slidably installed at the outlet end of the metering tube 32. The two ends of the connecting rod 514 are fixedly connected to the first cover plate 512 and the second cover plate 513, respectively.

[0038] The second cover plate 513 is fixedly connected to a pressure rod 511, which is slidably connected to the support frame 33. One end of the first spring 52 is fixedly connected to the pressure rod 511, and the other end is fixedly connected to the side wall of the support frame 33. Under normal conditions, the first spring 52 forces the first cover plate 512 to open the inlet end of the metering tube 32 and the second cover plate 513 to close the outlet end of the metering tube 32. When the pressure rod 511 forces the combined cover body 51 to move downward as a whole, the second cover plate 513 opens the outlet end of the metering tube 32 and the first cover plate 512 closes the inlet end of the metering tube 32.

[0039] Reference Figure 3 , Figure 6 A first guide rail 12 is fixedly installed on the elevated platform 1. The first guide rail 12 is located on one side of the storage bin 3, and both ends of the first guide rail 12 extend along the arrangement direction of the multiple storage bins 3 (only one storage bin 3 is shown in the figure in this embodiment). A material picking platform 6 is slidably installed on the first guide rail 12. The material picking platform 6 can be driven by a linear motor (not shown in the figure) so that the material picking platform 6 can slide along the length direction of the first guide rail 12.

[0040] A second guide rail 67 is fixedly installed on the side wall of the material handling platform 6. The second guide rail 67 is vertically arranged, and a lifting seat 61 is slidably installed on the second guide rail 67. A translation frame 64 is installed on the side wall of the lifting seat 61. The translation frame 64 is slidably installed on the lifting seat 61 so that it can approach or move away from the storage tank 3. A metering cylinder 7 is fixedly connected to the end of the translation frame 64 near the storage tank 3. The metering cylinder 7 is used to receive the raw material output from the metering tube 32 and transfer it to the feeding conduit 2. The metering cylinder 7 and the translation frame 64 are connected by a clamp 642.

[0041] It should be noted that in this embodiment, the feeding hopper 21 of the feeding conduit 2 and the metering tube 32 of the storage tank 3 are staggered. Each feeding hopper 21 of the feeding conduit 2 can receive raw materials from each storage tank 3 through the metering cylinder 7, depending on the actual raw material ratio required by the injection molding machine. In addition, a stirring structure needs to be installed at the feed hopper of the injection molding machine in this embodiment to uniformly stir two or more raw materials.

[0042] A pressure block 643 is fixedly installed on the clamp 642 of the translation frame 64. The pressure block 643 is used to press the pressure rod 511 of the combined cover 51 to open the metering tube 32. The lifting seat 61 presses the pressure rod 511 through the pressure block 643 of the translation frame 64. The specific operation is as follows: the translation frame 64 is driven to slide towards one side of the storage tank 3, so that the pressure block 643 moves above the pressure rod 511, and then the lifting seat 61 moves down to press down the pressure rod 511.

[0043] A rotating shaft 62 is rotatably mounted on the side wall of the material handling platform 6. In this embodiment, the rotating shaft 62 is driven by a drive motor 68. The drive motor 68 is fixedly mounted on the side wall of the material handling platform 6. The output shaft of the drive motor 68 and the rotating shaft 62 can be connected in series by a transmission belt (not shown in the figure) to drive the rotating shaft 62 to rotate.

[0044] Reference Figure 6 , Figure 7 , Figure 8 A first guide plate 63 is fixedly installed on the rotating shaft 62. The outer wall of the first guide plate 63 forms a first guide surface 631. A first roller 611 is rotatably installed on the side wall of the lifting seat 61. Under the action of the gravity of the lifting seat 61, the first roller 611 abuts against the first guide surface 631 of the first guide plate 63. It should be noted that the gravity of the lifting seat 61 is greater than the elastic force of the first spring 52.

[0045] The first guide surface 631 includes a first arc segment 632 and a second arc segment 633. The distance from the first arc segment 632 to the center of the rotating shaft 62 is greater than the distance from the second arc segment 633 to the center of the rotating shaft 62. When the first roller 611 rotates into the first arc segment 632, the lifting seat 61 rises; when the first roller 611 rotates into the second arc segment 633, the lifting seat 61 moves downward. It should also be noted that in this embodiment, there are two of each of the first arc segment 632 and the second arc segment 633. The two first arc segments 632 are symmetrically distributed around the central axis of the rotating shaft 62. A first connecting segment 634 is provided between the first arc segment 632 and the second arc segment 633. The first arc segment 632, the second arc segment 633, and the first connecting segment 634 together form the first guide surface 631, so that the lifting seat 61 can reciprocate and rise and fall when the rotating shaft 62 rotates.

[0046] A second guide plate 65 is fixedly mounted on the rotating shaft 62. The first guide plate 63 and the second guide plate 65 are arranged in a staggered manner along the axial direction of the rotating shaft 62, and the outer wall of the second guide plate 65 forms a second guide surface 651. The material handling platform 6 is provided with a push-pull assembly for driving the translation frame 64 to slide. The push-pull assembly includes a swing frame 66, a second roller 661, and a third roller 662. The swing frame 66 is hinged to the material handling platform 6. The second roller 661 and the third roller 662 are rotatably mounted at both ends of the swing frame 66. The second roller 661 abuts against the second guide surface 651. A push-pull groove 641 for the third roller 662 to be inserted is opened at the end of the translation frame 64 away from the metering cylinder 7. The two ends of the push-pull groove 641 extend along the height direction. Under normal circumstances, the swing frame 66 pulls the translation frame 64 to slide away from the storage tank 3 under its own weight.

[0047] The second guide surface 651 includes a third arc segment 652 and a fourth arc segment 653, with a second connecting segment 654 between the third arc segment 652 and the fourth arc segment 653. The third arc segment 652, the fourth arc segment 653, and the second connecting segment 654 together form the second guide surface 651. The distance from the third arc segment 652 to the center of the rotating shaft 62 is greater than the distance from the fourth arc segment 653 to the center of the rotating shaft 62. When the second roller 661 rotates into the third arc segment 652, the translation frame 64 slides towards the side closer to the storage tank 3. When the second roller 661 rotates into the fourth arc segment 653, the translation frame 64 slides away from the side away from the storage tank 3.

[0048] When the second roller 661 rotates into the third arc segment 652 (i.e., the translation frame 64 slides towards the side closer to the storage bin 3), the first roller 611 moves from the first arc segment 632 to the second arc segment 633 (i.e., the lifting seat 61 moves down). When the second roller 661 rotates out of the third arc segment 652 (i.e., the translation frame 64 slides away from the side farther from the storage bin 3), the first roller 611 moves from the second arc segment 633 to the first arc segment 632 (i.e., the lifting seat 61 rises).

[0049] The specific material handling action of the metering cylinder 7 in this embodiment is as follows: the metering cylinder 7 is transferred to one side of the storage tank 3 by the sliding of the material handling platform 6, and then the rotating shaft 62 is driven to rotate. Under the action of the second guide plate 65 (the second roller 661 rotates from the fourth arc segment 653 to the third arc segment 652), the metering cylinder 7 is driven to extend below the metering tube 32 of the storage tank 3, and the pressure block 643 is located above the pressure rod 511. As the rotating shaft 62 rotates, under the action of the first guide plate 63 (the first roller 611 rotates from the first arc segment 632 to the second arc segment 633), the lifting seat 61 is driven to move down. The lifting seat 61 drives the translation frame 64 to move down, thereby pressing the pressure rod 511 to open the metering tube 32, so that the raw material in the metering tube 32 falls into the metering cylinder 7.

[0050] As the rotating shaft 62 rotates, the first roller 611 first moves from the second arc segment 633 to the first arc segment 632, causing the lifting seat 61 to rise and close the metering tube 32 after the material discharge is completed. After the lifting seat 61 is raised, as the rotating shaft 62 rotates, the second roller 661 moves from the third arc segment 652 to the fourth arc segment 653, thereby causing the metering cylinder 7, which has completed the material removal, to move away from below the storage tank 3.

[0051] Reference Figure 6 , Figure 9 The metering cylinder 7 is open at both the top and bottom. The lower end of the metering cylinder 7 forms a material sliding port. A material taking cover plate 71 is slidably installed at the material sliding port. A second spring 72 is installed between the material taking cover plate 71 and the metering cylinder 7. One end of the second spring 72 is fixedly connected to the material taking cover plate 71, and the other end is fixedly connected to the metering cylinder 7. Under normal conditions, the second spring 72 forces the material taking cover plate 71 to slide away from the material taking platform 6 to cover the material sliding port.

[0052] An abutment rod 11 is fixedly connected to the elevated platform 1. The material pick-up cover 71 has an abutment part 711 that abuts against the abutment rod 11. When the metering cylinder 7 extends and moves above the feeding hopper 21, the abutment rod 11 pushes the abutment part 711 to open the material pick-up cover 71. The surface of the abutment part 711 near the abutment rod 11 is wavy.

[0053] The implementation principle of Embodiment 2 of this application is as follows: By setting a combined cover 51 inside the metering tube 32, under normal conditions, the combined cover 51, under the action of the first spring 52, opens the inlet end of the metering tube 32 and closes the outlet end of the metering tube 32, allowing the raw material in the storage tank 3 to fill the metering tube 32, thus storing a certain amount of raw material in the metering tube 32. The effect achieved is that the amount of raw material discharged from the storage tank 3 is fixed each time the combined cover 51 moves down, realizing precise control of the amount of raw material input required by the injection molding machine.

[0054] In practical applications, if the injection molding machine requires a mixture of two or more raw materials, the raw materials in multiple specific storage tanks 3 can be sequentially collected by the metering cylinder 7 and mixed in the required proportions to obtain the desired mixture for the injection molding machine. This design allows the storage tanks 3 to store a single type of raw material, eliminating the need for pre-mixing during storage. The mixing and proportioning of the raw materials is completed on-site by taking materials from the metering cylinder, significantly reducing the overall process steps.

[0055] The specific material handling action of the metering cylinder 7 is as follows: The metering cylinder 7 is moved to one side of the storage bin 3, driving the rotating shaft 62 to rotate. With the cooperation of the first guide plate 63 and the second guide plate 65, the metering cylinder 7 first slides towards one side of the storage bin 3 to move below the metering tube 32; then the metering cylinder 7 moves downwards, causing the metering tube 32 to open, allowing the raw material in the metering tube 32 to fall into the metering cylinder 7; then the metering cylinder 7 moves upwards, closing the metering tube 32 (at this time, the raw material in the storage bin 3 is replenished into the metering tube 32); finally, the metering cylinder 7 retracts, thus moving out from below the storage bin 3. All actions are controlled by the rotation angle of the rotating shaft 62, greatly improving the overall ease of operation.

[0056] After the material is picked up, the metering cylinder 7 can be transferred to the next storage tank 3 for further material picking by sliding the material picking platform 6, or transferred to the feeding hopper 21 to be fed into the injection molding machine.

[0057] The above are preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made to the structure, shape and principle of this application should be covered within the scope of protection of this application.
