Abstract
Description
Technical Field
[0001] This utility model relates to a feeding machine, and more particularly to a feeding machine that allows for smooth feeding. Background Technology
[0002] In the field of plastic extrusion processing, loss-in-weight feeders are one of the important devices for feeding plastic extruders. These feeders have an inlet at the top connected to the outlet of an external feed hopper. A feed pipe is connected to the outlet of the feed hopper, and the lower end of the feed pipe is connected to the feeder's inlet. To prevent the feed pipe from separating from the feeder's inlet due to equipment vibration during feeding, a rubber flexible joint is usually fixed to the end of the feed pipe in the feed hopper. The upper end of the flexible joint is fixedly connected to the lower end of the flexible joint via a clamp, which is also fixed to the feeder's inlet. This flexible joint connection prevents the feed pipe from shifting due to vibration of the feed hopper, ensuring a certain degree of elasticity between the feed pipe and the feeder's inlet and guaranteeing reliable feeding. However, because the flexible joint is prone to stretching, the outer periphery can collapse after stretching, easily leading to material accumulation.
[0003] In addition, in the existing feeder, after the feeder is fed into the feed bin, the material falls vertically into the feed bin and tends to pile up in the middle. The material in the feed bin is not evenly distributed, and the center of the piled-up material is subjected to greater compressive force, which puts pressure on the spiral feeding mechanism below and affects the discharge effect. Summary of the Invention
[0004] The technical problem to be solved by this utility model is to provide a feeding machine that ensures smooth feeding between the feeding bin and the feeding machine, prevents material accumulation, and ensures that the material in the feeding bin is evenly distributed.
[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:
[0006] A feeding machine with smooth feeding includes a hopper and a cover plate disposed on the top of the hopper. A feeding head for connecting a feed hopper pipe is disposed at the center of the top of the cover plate. The feeding head is vertically connected to the inside of the hopper and has a funnel-shaped structure. The end of the feed hopper pipe is sleeved inside the feeding head. A distributor is disposed inside the hopper and is coaxially disposed with the feeding head. The distributor consists of a suspension rod and a distribution plate disposed on the suspension rod. The suspension rod is vertically disposed and is suspended below the bottom of the cover plate by a horizontally disposed boom. The distribution plate is connected to the suspension rod through a base. The base has a triangular structure on the side and a downward sloping top. The distribution plate is fixedly installed on the sloping top of the base.
[0007] Furthermore, the top center of the cover plate is provided with an upwardly protruding threaded joint, and the center of the threaded joint is provided with a feeding port that penetrates the bottom of the cover plate; the feeding head is threadedly connected to the threaded joint; the inner side of the threaded joint is provided with a hanging groove that communicates with its top; the boom is horizontally positioned, with one end embedded in the hanging groove and the other end fixedly connected to the boom rod.
[0008] Furthermore, the hanging slots are at least three in number, and the three hanging slots are arranged in a circular array with the center of the end face of the threaded joint as the center; a hanging hole is provided on the outer side of the hanging rod near the top, and the number of the hanging holes is the same as the number and spacing angle of the hanging slots, and one end of the hanging arm is installed in the hanging hole.
[0009] Furthermore, the side of the boom is provided with an assembly guide groove with a "T" shaped end face along its length direction. The assembly guide groove extends upward through the top of the boom. One side of the base slides up and down with the assembly guide groove, and the base is embedded in the assembly guide groove.
[0010] Furthermore, the assembly guide groove has three grooves, which are arranged in a circular array with the axis of the boom as the center.
[0011] Furthermore, the outside of the boom is provided with external threads, and a limit nut is screwed onto the external threads. There are two limit nuts, which are respectively screwed onto the boom at the upper and lower ends of the base.
[0012] Compared with the prior art, the advantages of this utility model are: the feeding hopper at the top of this smooth feeding machine can wrap the lower end of the feed tube in the replenishment bin without a rigid connection, ensuring that the flexible connection at the lower end of the feed tube in the replenishment bin will not be stretched, thus preventing material accumulation and ensuring smooth feeding; through the distributor set below the feeding port, the material fed from the feeding port can be dispersed to all sides through the distribution plate, preventing the material from falling vertically into the feeding bin, avoiding material accumulation, ensuring the operational stability and feeding effect of the spiral feeding mechanism below the feeding machine, and ensuring the stability and reliability of the feeding machine operation.

[0028] Example
[0029] Please refer to the instruction manual attached. Figures 1 to 4 As shown, the instruction manual is attached. Figures 1 to 4 The image shows a specific embodiment of a smooth-feeding machine according to this utility model. The smooth-feeding machine includes a hopper 1 and a cover plate 11 disposed on top of the hopper 1. The cover plate 11 is fixedly connected to the hopper 1 by a snap fastener and is detachable. See the attached instruction manual. Figure 5 As shown, a feeding head 12 for connecting the feed hopper pipe 2 is provided at the center of the top of the cover plate 11. The feeding head 12 is vertically connected to the inside of the hopper 1, facilitating the feeding of material into the hopper 1. To solve the problem of material accumulation caused by the fixed connection between the lower flexible connection end of the feed hopper pipe 2 and the feeding head 12, please refer to the appendix of the instruction manual. Figure 3 and 4 As shown, the feeding head 12 has a funnel-shaped structure. The diameter of its upper end is larger than the diameter of the feed hopper pipe 2 and its lower flexible connection, and its height must be higher than the height of the flexible connection. The end of the feed hopper pipe 2 and the flexible connection connected to it are fitted inside the feeding head 12 without needing to be fixed. This avoids stretching of the lower flexible connection caused by vibration of the feed hopper pipe, thus preventing material accumulation. To improve the flexibility of the feeder, the feeding hopper 12 and the cover plate 11 are detachably connected. For details, please refer to the appendix of the instruction manual. Figure 3 , 4 As shown in Figure 8, a threaded connector 111 protruding upwards is provided at the top center of the cover plate 11. The threaded connector 111 has a threaded protrusion on its outer circumferential surface. The threaded connector 111 is integrally formed with the cover plate 11. In order to facilitate the feeding of material from the replenishment bin to the feeding bin 1 through the threaded connector 111, a feeding port 1111 penetrating downwards through the bottom of the cover plate 11 is provided at the top center of the threaded connector 111. The material fed into the feeding hopper 12 through the replenishment bin material pipe 2 will enter the feeding bin 1 through the feeding port 1111. The feeding head 12 and the threaded connector The feed head 12 is threaded together with the threaded connector 111. The inner side of the feed head 12, near its lower end, has an internal thread that mates with the external thread on the threaded connector 111. The feed head 12 and the threaded connector 111 are threaded together, facilitating easy assembly and disassembly. Different diameter feed hoppers 12 can be replaced as needed, improving the flexibility of the feeder. To ensure that the material entering the feed bin 1 from the feed inlet 111 is dispersed and to prevent material from falling vertically into the feed bin 1 and causing material accumulation, which could affect the subsequent screw mechanism feeding, please refer to the attached manual. Figures 5 to 7 As shown, a distributor 3 is installed inside the hopper 1. (Refer to the attached instruction manual.) Figure 3 and 4 As shown, the distributor 3 and the feed head 12 are coaxially arranged vertically and on the same center line; refer to the appendix of the instruction manual. Figures 4 to 7As shown, the distributor 3 consists of a lifting rod 31 and a distributing disc 34 mounted on the lifting rod 31. The lifting rod 31 is a cylindrical rod, vertically arranged, and is suspended below the bottom of the cover plate 11 by a horizontally arranged lifting arm 36. The lifting arm 36 is connected to the lifting rod 31 near the upper end. To facilitate the installation of the lifting arm 36 on the cover plate 11, the inner side of the threaded joint 111 is provided with a hanging groove 1112 that communicates with its top. The lifting arm 36 is horizontally arranged, with one end embedded in the hanging groove 1112 and the other end fixedly connected to... To ensure the balance of the suspension rod 31, at least three suspension slots 1112 are provided on the rod 31. These three slots are arranged in a circular array with the center of the end face of the threaded joint 111 as the center. Each slot 1112 contains a corresponding lifting arm 36. To facilitate the connection between the lifting arm 36 and the rod 31, a lifting hole 311 is provided on the outer side of the rod 31 near the top. One end of the lifting arm 36 is installed in the lifting hole 311. The number of lifting holes 311 corresponds to the number and spacing of the suspension slots 1112. The same angles facilitate the correspondence between the number and spacing of the lifting arms 36 connected in the lifting holes 311 and the number and spacing of the hanging slots 1112, ensuring easy fit. The lifting arms 36 and the lifting holes 311 can be connected by either a plug-in connection or a threaded connection. The distribution plate 34 is connected to the lifting rod 31 via a base 341. The base 341 and the lifting rod 31 are connected together, and its side has a triangular structure, ideally a right-angled triangle. Process holes can be opened on the side, reducing the weight of the base 341 while increasing its own height. To ensure strength, the top of the base 341 is a downward-sloping surface, with the slope decreasing from one side of the lifting rod 31 to the other. The distribution plate 34 is fixedly installed on the slope of the top of the base 341, also with a downward slope, corresponding to the inner side of the feeding bin 1. The top surface of the distribution plate 34 has a groove, which facilitates the material falling into the groove to fall outward and downward. To facilitate the vertical adjustment of the base 341 on the lifting rod 31 and adapt to different feeding bins 1, thus improving flexibility, please refer to the appendix of the instruction manual. Figure 7 As shown, the side of the boom 31 is provided with an assembly guide groove 32 with a "T"-shaped end face along its length. The assembly guide groove 32 extends upward through the top of the boom 31. The base 341 is embedded in the assembly guide groove 32. To facilitate the assembly and connection of the base 341 on the assembly guide groove 32, one end of the base 341 matches the structural shape of the assembly guide groove 32, and it can slide up and down within the assembly guide groove 32 after being embedded in it. To limit the height position of the base 341 on the boom 31, please refer to the appendix of the specification. Figure 7As shown, the external thread 33 of the boom 31 is provided, and a limiting nut 35 is screwed onto the external thread 33. There are two limiting nuts 35, which are screwed onto the upper and lower ends of the base 341 on the boom 31, respectively. The two limiting nuts 35 can limit the height position of the base 341 on the boom 31. In order to ensure that the material entering from the feed port 1111 can be effectively dispersed to the surrounding area by the distributor 3 and to ensure that the material falling into the feed bin 1 will not accumulate in the center, there are at least three assembly guide grooves 32. The three assembly guide grooves 32 are arranged in a circular array with the axis of the boom 31 as the center. Each assembly guide groove 32 has a base 341 that slides and engages with it. Each base 341 is provided with a distribution plate 34. The multiple distribution plates 34 are evenly arranged around the outer perimeter of the boom 31.
[0030] In use, the base 341 equipped with the feeder 34 is installed on the lifting rod 31 through the mounting guide groove 32. The height position of the base 341 on the lifting rod 31 is fixed by the upper and lower limit nuts 35. Then, the top of the lifting rod 31 is passed upward through the feeding port 111, and the lifting arm 36 is installed in the lifting rod 311 of the lifting rod 31. Then, the outer end of the lifting arm 36 is placed in the hanging groove 1112 of the threaded joint 111 to realize the installation of the feeder 3 on the cover plate 11. Next, the feeding head 12 is screwed onto the threaded joint 111 of the cover plate 11. Then, the cover plate 11 is closed on the top opening of the feeding bin 1. The cover plate 11 and the feeding bin 1 are fixedly connected together by the buckle. Finally, the lower end of the feeding bin material pipe 2 on the feeding bin is placed in the feeding hopper 12 to replenish the feeder. The flexible connector at the lower end of the feed hopper 2 is completely placed inside the feed hopper 12, corresponding vertically to the feed port 1111. The flexible connector at the lower end of the feed hopper 2 placed inside the feed hopper 12 is not rigidly connected to the feed hopper 12, so it will not stretch due to long-term use, avoiding material accumulation and ensuring smooth feeding. The material entering the feed hopper 1 from the feed port 1111 will naturally fall above the distribution plate 34 and spread out to the surrounding areas of the feed hopper 1 through the distribution plate 34. Some material falls directly from the gaps between the distribution plates 34, avoiding the phenomenon of material only accumulating in the center of the feed hopper 1, ensuring the balance of material in the feed hopper 1, and ensuring the stability of the feeding by the threaded feeding mechanism connected below the feed hopper 1.
[0031] This type of feeder with smooth feeding can have its top feeding hopper 12 completely enclose the lower end of the feed tube 2 of the replenishment bin without the need for a rigid connection. This ensures that the flexible connection at the lower end of the feed tube 2 of the replenishment bin will not be stretched, thus preventing material accumulation and ensuring smooth feeding. The distributor 3 set below the feeding port 1111 can disperse the material fed from the feeding port 1111 to the surrounding areas through the distribution plate 34, preventing the material from falling vertically into the feed bin 1 and avoiding material accumulation. This ensures the operational stability and feeding effect of the spiral feeding mechanism below the feeder, and guarantees the stability and reliability of the feeder's operation.
[0032] It should be emphasized that the above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
