Abstract
Description
Technical Field
[0001] This utility model relates to the field of mineral processing technology, and in particular to a device for unblocking cold-pressed pellets at the feed inlet. Background Technology
[0002] In the production of cold-pressed pellets, clogging of the feed inlet is a common and troublesome problem. Since the raw materials for cold-pressed pellets are mostly fine powders, they are prone to accumulating and clumping at the feed inlet and channel due to their high moisture content. Traditional methods require frequent shutdowns for manual cleaning, which is not only inefficient but also poses safety hazards. Furthermore, material accumulation can lead to a decrease in molding quality and an increase in energy consumption. Therefore, a device for clearing clogging of the feed inlet in cold-pressed pellets is needed to ensure continuous production and reduce maintenance costs.
[0003] In existing cold-pressed pellet production technology, when the moisture content of raw materials is too high, the feed channel is prone to sticking and clogging. Traditional equipment often relies on a single rotating structure for unblocking, which cannot transport large pieces of raw materials and has limited effect on removing materials adhering to the inner wall. This often leads to blockage of the feed channel and inability to work, which not only increases maintenance costs and downtime losses, but also causes fluctuations in pellet forming quality due to poor feed uniformity, making it difficult to meet the needs of efficient and continuous production. Utility Model Content
[0004] To overcome the above shortcomings, this utility model provides a cold-pressed pellet unblocking device for preventing blockage of the feed inlet, which aims to improve the problems of not being able to unblock large pieces of raw materials and not being able to remove raw materials adhering to the inner wall.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a device for unblocking cold-pressed pellets in a discharge port, comprising a housing, a first support plate fixedly connected to the upper surface of the housing, a second motor fixedly connected to the outer wall of the first support plate, a rotating block fixedly disposed at the output end of the second motor, a second support plate fixedly connected to the upper surface of the housing, a blocking block fixedly connected to the inner wall of the second support plate, a hammer rotatably connected inside the second support plate, the upper surface of the blocking block fitting against the outer wall of the hammer, the outer wall of the hammer fitting against the outer wall of the rotating block, a shell fixedly connected to the upper surface of the housing, a first motor fixedly connected to the upper surface of the shell, a stirring assembly disposed at the output end of the first motor, the stirring assembly being used to unblock the channel.
[0006] Preferably, the stirring assembly includes a stirring shaft, the upper surface of which is fixedly connected to the output end of the first motor, and stirring blades are fixedly connected to the outer wall of the stirring shaft.
[0007] Preferably, a first motor is fixedly connected to the outer wall of the housing, and a second pressure roller is fixedly installed at the output end of the first motor. The outer wall of the second pressure roller is rotatably connected to the inside of the housing.
[0008] Preferably, the outer wall of the second pressure roller is provided with a track, and the inner wall of the track is provided with a first pressure roller, and the outer wall of the first pressure roller is rotatably connected to the inside of the housing.
[0009] Preferably, a conveyor plate is fixedly connected to the inner wall of the box, a support leg is fixedly connected to the lower surface of the box, and a collection box is fixedly connected to the lower surface of the box.
[0010] Preferably, the inside of the collection box is rotatably connected to a rotating shaft, the outer wall of the rotating shaft is fixedly connected to a gear, and the outer wall of the gear is fixedly connected to a rotating plate.
[0011] Preferably, the upper surface of the rotating plate is slidably connected to the lower surface of the collection box, and a fixed plate is rotatably connected to the outer wall of the rotating shaft.
[0012] Preferably, a second motor is fixedly connected to the outer wall of the fixing plate, and the output end of the second motor is fixedly connected to one end of the rotating shaft.
[0013] This utility model has the following beneficial effects:
[0014] 1. In this utility model, when the rotating block rotates, it continuously strikes the bottom of the striking hammer, causing the striking hammer to rotate inside the second support plate and continuously strike the outer wall of the shell. The blocking block limits the rotation angle of the striking hammer, stirring and clearing the large pieces of raw materials in the shell channel. Furthermore, the striking hammer strikes the shell and vibrates the raw materials adhering to the inner wall, causing them to detach from the inner wall. This prevents the cold-pressed pellets from accumulating and clogging, ensuring smooth material feeding and providing a guarantee for the efficient and stable production of cold-pressed pellets, thereby improving production efficiency.
[0015] 2. In this utility model, the second motor on the outer wall of the fixed plate is started to make the rotating shaft rotate inside the collection box. When the rotating shaft rotates, it drives the gear on the outer wall and the rotating plate to rotate synchronously, thereby opening the rotating plate to feed the cold-pressed pellets inside the collection box. The quantitative feeding of cold-pressed pellets can ensure the stability of materials in subsequent processes, prevent overload or material shortage, reduce losses, facilitate automated control, reduce waste, and ensure efficient and stable production.

Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0024] Reference Figures 1-2 An embodiment of this utility model provides a device for clearing cold-pressed pellets from a clogged feed inlet, comprising a housing 11, a first support plate 7 fixedly connected to the upper surface of the housing 11, a second motor 8 fixedly connected to the outer wall of the first support plate 7, a rotating block 6 fixedly provided at the output end of the second motor 8, a second support plate 9 fixedly connected to the upper surface of the housing 11, a blocking block 10 fixedly connected to the inner wall of the second support plate 9, a hammer 5 rotatably connected inside the second support plate 9, the upper surface of the blocking block 10 being in contact with the outer wall of the hammer 5, the outer wall of the hammer 5 being in contact with the outer wall of the rotating block 6, a housing 1 fixedly connected to the upper surface of the housing 11, a first motor 2 fixedly connected to the upper surface of the housing 1, and a stirring assembly provided at the output end of the first motor 2 for clearing channels;
[0025] Specifically, the first support plate 7 is fixed by the housing 11, which in turn provides fixed support for the second motor 8. When the second motor 8 starts, it drives the rotating block 6 at the output end to rotate. The second support plate 9 is fixed by the housing 11. When the rotating block 6 rotates, it will come into contact with the outer wall of the hammer 5, causing the hammer 5 to rotate through the second support plate 9. The second support plate 9 supports the rotation of the hammer 5. The blocking block 10 is fixed by the second support plate 9. After the hammer 5 rotates to a certain angle, it will come into contact with the blocking block 10. The blocking block 10 limits the rotation of the hammer 5. The housing 1 is fixed by the housing 11. Then, the hammer 5 continuously strikes the outer wall of the housing 1 through the power of the rotating block 6 and the limiting effect of the blocking block 10, achieving the effect of vibrating and removing the raw materials adhering to the inner wall of the channel. The first motor 2 is fixed by the housing 1.
[0026] Reference Figures 1-2 The stirring assembly includes a stirring shaft 3, the upper surface of which is fixedly connected to the output end of the first motor 2, and stirring blades 4 are fixedly connected to the outer wall of the stirring shaft 3.
[0027] Specifically, when the first motor 2 starts, it drives the stirring shaft 3 at the output end to rotate. When the stirring shaft 3 rotates, it drives the stirring blade 4 to rotate synchronously inside the housing 1, thereby achieving the effect of conveying large pieces of raw materials and preventing blockage of the channel.
[0028] Reference Figure 1 and Figure 3 A first motor 15 is fixedly connected to the outer wall of the housing 11. A second pressure roller 13 is fixedly installed at the output end of the first motor 15. The outer wall of the second pressure roller 13 is rotatably connected to the inside of the housing 11. A track 16 is installed on the outer wall of the second pressure roller 13. A first pressure roller 12 is installed on the inner wall of the track 16. The outer wall of the first pressure roller 12 is rotatably connected to the inside of the housing 11.
[0029] Specifically, the first motor 15 is fixed by the housing 11. When the first motor 15 starts, it drives the second pressure roller 13 at the output end to rotate. When the second pressure roller 13 rotates, it drives the first pressure roller 12 to rotate synchronously inside the housing 11 through the connection of the track 16. The housing 11 supports the rotation of the second pressure roller 13 and the first pressure roller 12. The raw material is squeezed and shaped by the groove on the surface of the second pressure roller 13 through the housing 11, thereby achieving the effect of forming cold-pressed pellets.
[0030] Reference Figures 3-5A conveyor plate 18 is fixedly connected to the inner wall of the box 11, a support leg 19 is fixedly connected to the lower surface of the box 11, a collection box 17 is fixedly connected to the lower surface of the box 11, a rotating shaft 14 is rotatably connected inside the collection box 17, a gear 23 is fixedly connected to the outer wall of the rotating shaft 14, a rotating plate 20 is fixedly connected to the outer wall of the gear 23, the upper surface of the rotating plate 20 is slidably connected to the lower surface of the collection box 17, a fixed plate 21 is rotatably connected to the outer wall of the rotating shaft 14, a second motor 22 is fixedly connected to the outer wall of the fixed plate 21, and the output end of the second motor 22 is fixedly connected to one end of the rotating shaft 14.
[0031] Specifically, the conveyor plate 18 is fixed by the housing 11, the support leg 19 is fixed by the housing 11, and the housing 11 also serves to fix the collection box 17. The cold-pressed pellets are gathered by the conveyor plate 18 and fall into the collection box 17. The second motor 22 is fixed by the fixing plate 21. When the second motor 22 starts, it drives the output shaft 14 to rotate inside the fixing plate 21 and the collection box 17. The fixing plate 21 and the collection box 17 support the rotation of the shaft 14. When the shaft 14 rotates, it drives the gear 23 on the outer wall and the rotating plate 20 to rotate synchronously, thereby causing the rotating plate 20 to open to both sides and causing the cold-pressed pellets to fall into the collection box 17, achieving the effect of quantitative feeding of cold-pressed pellets.
[0032] Working Principle: When this device is needed, the raw material for cold-pressed pellets is placed inside the shell 1. If the raw material has excessive moisture, it can easily cause the channels to stick and become clogged. The first motor 2 is started, rotating the stirring blades 4 via the stirring shaft 3 at the output end to clear the blockage. The second motor 8 is started, causing the rotating block 6 at the output end to rotate inside the first support plate 7. As the rotating block 6 rotates, it continuously strikes the bottom of the striking hammer 5, causing the striking hammer 5 to rotate inside the second support plate 9 and continuously strike the outer wall of the shell 1. The blocking block 10 limits the rotation angle of the striking hammer 5, thereby vibrating the raw material adhering to the inner wall of the shell 1 and causing it to detach from the inner wall. This prevents the cold-pressed pellets from accumulating and clogging, ensuring smooth feeding, reducing material waste, ensuring uniform feeding, reducing downtime for maintenance due to blockage, lowering maintenance costs, and making the equipment more reliable. This provides a guarantee for the efficient and stable production of cold-pressed pellets, improving production efficiency.
[0033] Raw materials are fed into the device and fixed to the support legs 19 by the housing 11. The first motor 15 is started to rotate the second pressure roller 13 at the output end. When the second pressure roller 13 rotates, the first pressure roller 12 rotates synchronously inside the housing 11 via the crawler 16, extruding the raw materials to form cold-pressed pellets. The conveyor plate 18 conveys the scattered cold-pressed pellets into the collection box 17. The second motor 22 on the outer wall of the fixing plate 21 is started to rotate the shaft 14 inside the collection box 17. When the shaft 14 rotates, it drives the gear 23 on the outer wall and the rotating plate 20 to rotate synchronously, thereby opening the rotating plate 20 to unload the cold-pressed pellets inside the collection box 17. Quantitative unloading of cold-pressed pellets can ensure the stability of materials in subsequent processes, avoid pressure fluctuations, improve pellet forming quality, match equipment processing capacity, prevent overload or material shortage, reduce losses, facilitate automated management, reduce waste, and ensure efficient and stable production.
