Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of feeders, and in particular relates to a feeder for a roller press. Background Art
[0002] Roller press, also known as extrusion mill, roller mill, and roller press, is mainly composed of a frame, two roller systems, a transmission device, a torque support, a roller cover, a feeding device, a hydraulic system, a main bearing lubrication system, a dry oil lubrication system, an electrical system, a roller removal device, etc. The roller press is designed according to the principle of bed grinding. Its main features are high pressure, full speed, full material, and bed crushing. It consists of a fixed roller and a movable roller. The material is fed from above the two rollers and is continuously brought into the roller space by the extrusion roller. After being subjected to high pressure, it becomes a dense cake and is discharged.
[0003] In the Chinese patent publication number CN213501085U, a DHS arc feeding device for a roller press is mentioned, which relates to the field of roller presses and includes two adjusting plates for adjusting the feed flow of the roller press and an adjusting control mechanism for adjusting and controlling the distance between the two adjusting plates. The lower ends of the two adjusting plates are respectively in contact with the two rollers of the roller press. The adjusting control of the adjusting control mechanism acts on the two adjusting plates. When the adjusting control mechanism adjusts and controls the distance between the two adjusting plates, the lower ends of the two adjusting plates rotate around the rotation centers of the two rollers respectively. The adjusting control mechanism includes two adjusting control members, each of which includes a connecting plate, a rotating plate, a power drive member and a supporting wheel. Through the action of the rotating plate, the connecting plate and the supporting wheel, the adjusting plate moves obliquely in an equidistant circular arc along the edge of the roller of the roller press when adjusting the feed flow of the roller press. The distance between the lower end of the adjusting plate and the roller remains unchanged, so that the material does not spill outward, thereby ensuring the stability of the material bed of the roller press.
[0004] During the use of this feeding device, the gate assembly does not move in a straight line during adjustment, but instead exhibits an arc-shaped motion pattern. This non-linear motion trajectory not only causes the gate assembly to move less smoothly during the adjustment process, but also significantly affects its overall stability. More importantly, this unstable motion state further interferes with the normal feeding process of the raw materials, making it difficult for the flow and distribution of the raw materials to achieve the expected uniformity and accuracy. Utility Model Content
[0005] The purpose of the present utility model is to provide a roller press feeder to solve the problems raised in the above background technology.
[0006] To achieve the above objectives, the present invention provides the following technical solutions:

[0012] Preferably, a supporting roller is installed at the other inner end of the connecting cover, and the end of the supporting roller away from the connecting cover passes through the connecting cover and is in close contact with the gate plate.
[0013] Preferably, a silo is installed at the top of the connecting cover, and an inspection door is provided at one end of the silo. Two roller press bodies are installed in the roller press body.

[0014] Preferably, the joint plates are all configured as V-shaped structures.
[0015] Preferably, the two side baffles and the two extension baffles are located on both sides of the two squeezing rollers.
[0016] Compared with the prior art, the beneficial effects of the present invention are:
[0017] (1) Through the arrangement of the driving mechanism, mounting plate, connecting plate, pulling plate, gate plate, guide rail, upper limit plate and side limit block, after the driving mechanism is started, its output end extends and pulls the connecting plate to move, and one end of the connecting plate rotates flexibly on the mounting plate, thereby prompting the other end of the connecting plate to pull the pulling plate to slide smoothly on the guide rail, so that the pulling plate drives the upper limit plate to perform tangential movement through the fixed block. During the displacement of the upper limit plate, the gate plate drives the side limit block to move together, thereby realizing the flexible adjustment of the distance between the two gate plates, ensuring that the movement trajectory of the gate plate is both reliable and stable, so that it can be stably adjusted according to the gap between the extrusion rollers, so that the flow and distribution of the raw materials can achieve the expected uniformity and accuracy.
[0018] (2) By setting up a silo, an inspection door, a side baffle and an extended baffle, polytetrafluoroethylene plates are used in the silo to replace the original ordinary steel plates. The surface of this material is smooth and can effectively prevent the adhesion of material powder, allowing it to slide naturally. When unloading, the material falls directly into the narrow channel between the two extrusion rollers along the upper limit plate and the side limit block under the action of gravity. The side baffles and extended baffles on both sides are set to improve the sealing of the device to ensure that the material can completely avoid leakage from the side during the unloading process and fall smoothly through the channel between the two extrusion rollers accurately and smoothly. The entire unloading process is both efficient and stable. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0025] Example 1:
[0026] See also Figure 1 - Figure 4 As shown, a roller press feeder comprises:
[0027] Roller press body 1;
[0028] A connecting cover 6 is installed at the top of the roller press body 1. Support seats 4 are installed on both sides of the top of the roller press body 1. The tops of the two support seats 4 are movably connected to the driving mechanism 5 through the rotating shaft. Side baffles 3 are provided on both sides of the bottom end of the connecting cover 6, and the bottom ends of the two side baffles 3 are provided with extension baffles 7.
[0029] Guide rails 16 are installed on both sides of the inner shell wall of the connecting cover 6, and the outer surfaces of the guide rails 16 are slidably connected to the pulling plates 14. One end of the pulling plate 14 is movably connected to the fixed block 19, and the bottom end of the fixed block 19 is fixedly connected with the upper limit plate 17. The bottom end of the upper limit plate 17 is fixedly connected with the gate plate 15, and the end of the gate plate 15 away from the upper limit plate 17 is fixedly connected to the side limit block 18, and the end of the pulling plate 14 away from the fixed block 19 is movably connected to the joint plate 13.
[0030] Depend on Figure 1 - Figure 4 It can be seen that the end of the connecting plate 13 away from the mounting plate 12 is movably connected to the output end of the driving mechanism 5, one end of the connecting plate 13 is movably connected to the mounting plate 12, and the mounting plate 12 is fixedly connected to the inner end of the connecting cover 6.
[0031] As can be seen from the above, the driving mechanism 5 is started, the output end of the driving mechanism 5 extends and pulls the connecting plate 13 to move, and one end of the connecting plate 13 rotates on the mounting plate 12, so that the other end of the connecting plate 13 pulls the pulling plate 14 to move, and makes the pulling plate 14 slide on the guide rail 16, so that the pulling plate 14 drives the upper limit plate 17 to perform tangential movement through the fixed block 19. When the upper limit plate 17 is displaced, it will drive the gate plate 15 to move, and the gate plate 15 drives the side limit block 18 to move, so that the distance between the two gate plates 15 can be adjusted.
[0032] Preferably, the joint plates 13 are all configured as V-shaped structures.
[0033] As can be seen from the above, the connecting plate 13 is set to a V-shaped structure, and one end of it is movably connected to the mounting plate 12. When the output end of the driving mechanism 5 is extended or retracted, the connecting plate 13 uses the end movably connected to the mounting plate 12 as a fulcrum to drive the pulling plate 14 to move.
[0034] Example 2:
[0035] refer to Figure 1 - Figure 4 As shown, a support roller 10 is installed at the other end of the inner side of the connecting cover 6, and the end of the support roller 10 away from the connecting cover 6 passes through the connecting cover 6 and is in close contact with the gate 15;
[0036] A silo 8 is installed at the top of the connecting cover 6, and an inspection door 9 is provided at one end of the silo 8. Two roller press bodies 1 are installed in the roller press body 1. Two dust shields 11 are fixedly connected to both sides of the top of the connecting cover 6, and the output ends of the two driving mechanisms 5 are respectively located below the two dust shields 11.
[0037] As can be seen from the above, by providing the support roller 10, the gate plate 15 can be effectively supported, and the smooth rotation of the roller can be achieved when the gate plate 15 moves, thereby significantly reducing friction while providing stable support and improving the flexibility of the gate plate 15. During the unloading process, the material is smoothly introduced into the silo 8 with a heightened design. The overall height of the silo 8 is increased, and an inspection door 9 is added. This design facilitates the inspection of the interior of the channel and the crusting of the material. In addition, the silo 8 is made of polytetrafluoroethylene plate with a smooth surface, which can effectively prevent material powder from adhering, ensuring that the material slides naturally during unloading, and the whole process is smoother.
[0038] Preferably, the two side baffles 3 and the two extension baffles 7 are located on both sides of the two squeezing rollers 2 .
[0039] As can be seen from the above, the side baffles 3 and the extension baffles 7 are provided to improve the sealing performance during material unloading.
[0040] Furthermore, when the present design is applied to the feeding of the roller press, when adjustments are required, the driving mechanism 5 is started, the output end of the driving mechanism 5 extends and pulls the connecting plate 13 movably connected thereto to move, and one end of the connecting plate 13 rotates on the mounting plate 12, so that the other end of the connecting plate 13 pulls the pulling plate 14 movably connected thereto to move, and causes the pulling plate 14 to slide on the guide rail 16, so that the pulling plate 14 drives the upper limit plate 17 to perform tangential movement through the fixed block 19 movably connected thereto, and when the upper limit plate 17 moves, it drives the gate plate 15 fixedly connected thereto to move, and the gate plate 15 drives the side limit block 18 fixedly connected thereto to move, so that the distance between the two gate plates 15 can be adjusted;
[0041] During the movement of the gate 15, the preset guide rail 16 provides a clear track for it, ensuring that the gate 15 can be opened and closed smoothly along this preset path, which not only ensures the convenience and smoothness of operation, but also ensures that the material can flow smoothly in the predetermined direction;
[0042] During unloading, the material is directly introduced into the silo 8 through the opening at the top of the silo 8. A polytetrafluoroethylene plate is used in the silo 8 instead of the original ordinary steel plate. The surface of this material is smooth, which can effectively prevent the material powder from adhering and realize natural sliding. Under the action of gravity, the material falls directly into the narrow channel between the two squeezing rollers 2 along the upper limit plate 17 and the side limit block 18. The side baffles 3 and the extended baffles 7 on both sides are provided to improve the sealing performance of the device to ensure that the material can completely avoid leakage from the side during the unloading process, and can fall smoothly through the channel between the two squeezing rollers 2 accurately and stably. The entire unloading process is both efficient and stable.
[0043] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
