Description

Technical Field

[0001] This utility model relates to the field of veterinary drug production technology, specifically to a veterinary drug granulator roller gap adjustment mechanism. Background Technology

[0002] Veterinary drugs refer to substances (including medicated feed additives) used to prevent, treat, or diagnose animal diseases or to purposefully regulate animal physiological functions. They mainly include serum products, vaccines, diagnostic products, microecological products, traditional Chinese medicine, and chemical drugs.

[0003] To make veterinary drugs more palatable to animals, farmers often mix them into food and granulate them using a pellet mill. When using a pellet mill to granulate materials, pressure rollers need to be installed at the feed hopper to compress the materials, allowing for better mixing and preventing large particles from affecting subsequent extrusion. However, since different drugs and foods have different particle sizes and hardness, and the pressure rollers require power to drive, they are often fixed in place, reducing their compression efficiency for different materials and resulting in low pelleting efficiency of the pellet mill.

[0004] Therefore, a gap adjustment mechanism for the pressure rollers of a veterinary drug granulator is proposed to solve the problems mentioned above. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a roller gap adjustment mechanism for a veterinary drug granulator, which can solve the problem that the gap between rollers cannot be effectively adjusted according to different materials.

[0007] The second gear meshes above the two first gears on opposite sides, and an arc-shaped groove is provided on the support plate, which is coaxial with the connecting shaft.

[0008] Two parallel pressure rollers are arranged between two support plates. The ends of the pressure rollers pass through the strip groove and are coaxially connected to the second gear. A strip plate is rotatably installed on the end of the pressure roller. The other end of the strip plate is rotatably installed on the connecting shaft. An inclined pushing mechanism is provided on one side of the strip plate. One end of the pushing mechanism is rotatably installed in the U-shaped seat, and the U-shaped seat is fixed on the end of the strip plate near the pressure roller. A rotating shaft is rotatably installed on the other end of the pushing mechanism. The rotating shaft is vertically fixed on the side of the support plate.

[0009] Preferably, a drive motor is provided on the outer side of one of the support plates, the drive motor is fixed to the support plate by a bracket, and the drive motor is coaxially connected to one of the first gears.

[0010] Preferably, a mounting base is installed along the edge of the support plate, and a limiting groove is formed along the outer wall of the mounting base.

[0011] Preferably, a telescopic cover is connected to both ends of the strip groove, the other end of the telescopic cover is connected to a ring, and the ring is fitted on the end of the pressure roller, with the ring rotatably connected to the end of the pressure roller.

[0012] Preferably, a box with openings at both ends is provided on one side of the two support plates that are relatively far apart. The box is fixed to the support plates along the edge of the support plates, and a cover plate is detachably installed on the other end of the box.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example:

[0025] Please see Figure 1 - Figure 5 This embodiment of a veterinary drug granulator roller gap adjustment mechanism includes two parallel support plates 1, with mounting bases 12 installed along the edges of the support plates 1, and limit grooves 13 formed along the outer wall of the mounting bases 12. In actual use, a feeding hopper (such as a feed hopper) is provided at the inlet of the granulator. Figure 5 (As indicated by the middle arrow A), slots corresponding to the support plate 1 are provided on both sides of the hopper, and the side wall thickness of the hopper also corresponds to the limiting groove 13. That is, the support plate 1 is embedded in the limiting groove 13 through the edge of the slot in the hopper, so as to realize the installation of the support plate 1 on the hopper. In order to further improve the stability of the support plate 1 on the hopper, bolts can be used to fix it to the mounting base 12, thereby connecting and fixing the mounting base 12 and the hopper.

[0026] like Figure 1 and Figure 3 As shown, two first gears 3 are provided on the side of the two support plates 1 that are relatively far apart. The two first gears 3 mesh with each other, and the first gears 3 are rotatably connected to the support plates 1 through the connecting shaft 2. The two first gears 3 can drive each other and move in opposite directions.

[0027] The two first gears 3 are meshed with the second gear 4 above each other on the opposite side. An arc-shaped groove 6 is provided on the support plate 1. The groove 6 is coaxially arranged with the connecting shaft 2. When the first gear 3 rotates, it can drive the second gear 4 on its side to rotate. In addition, the two first gears 3 move towards each other, which causes the second gears 4 to move towards each other as well. Therefore, two parallel pressure rollers 5 are provided between the two support plates 1. The ends of the pressure rollers 5 pass through the groove 6 and are coaxially connected with the second gear 4. The two pressure rollers 5 also move towards each other. When the material falls between the two pressure rollers 5, the material can be squeezed.

[0028] It should be noted that a drive motor 11 is provided on the outer side of one of the support plates 1. The drive motor 11 is fixed to the support plate 1 by a bracket, and the drive motor 11 is coaxially connected to one of the first gears 3 to provide power for the rotation of the pressure roller 5.

[0029] In order to reduce the amount of material falling from the strip groove 6 after extrusion, a telescopic cover is connected to both ends of the strip groove 6 during the extrusion of the material. The other end of the telescopic cover is connected to the ring sleeve, and the ring sleeve is fitted on the end of the pressure roller 5. The ring sleeve and the end of the pressure roller 5 are rotatably connected.

[0030] When it is necessary to adjust the distance between the two pressure rollers 5, such as Figure 1 and Figure 2 As shown, a strip plate 7 is rotatably mounted on the end of the pressure roller 5, and the other end of the strip plate 7 is rotatably mounted on the connecting shaft 2. An inclined pushing mechanism 8 is provided on one side of the strip plate 7. One end of the pushing mechanism 8 is rotatably mounted in a U-shaped seat 9, and the U-shaped seat 9 is fixed on the end of the strip plate 7 near the pressure roller 5. A rotating shaft 10 is rotatably mounted on the other end of the pushing mechanism 8. The rotating shaft 10 is vertically fixed on the side of the support plate 1. In actual use, the pushing mechanism 8 is either a hydraulic cylinder or an electric push rod. Under the action of the pushing mechanism 8, the strip plate 7 can be driven to rotate around the connecting shaft 2, thereby controlling the two pressure rollers 5 to move closer or further apart, realizing the adjustment of the distance between the two pressure rollers 5, which is beneficial for the effective extrusion operation of different materials.

[0031] Specifically, during use, the two pushing mechanisms 8 located on the same side of the support plate 1 always move in the same direction, and all pushing mechanisms 8 operate with the same amount of forward motion to ensure that the two pressure rollers 5 and both ends of the same pressure roller 5 move with the same amount of motion, so as to prevent the gears from being squeezed or damaged.

[0032] In addition, using four pushing mechanisms 8 to act on the pressure roller 5 is more efficient than using a single pushing mechanism 8. If only one pushing mechanism 8 is used, it is necessary to rely on gear transmission to drive another pressure roller 5, which will greatly increase the burden on the gears and may even cause damage to the gears.

[0033] It should be noted that in actual use, the drive motor 11 and the pushing mechanism 8 are both connected to the controller of the pellet mill via wires. When the pushing mechanism 8 is a hydraulic cylinder, its own hydraulic station can be set up on the side of the pellet mill.

[0034] It needs to be further explained that, such as Figure 4 As shown, a box 16 with openings at both ends is provided on one side of the two support plates 1 that are relatively far apart. The box 16 is fixed to the support plate 1 along the edge of the support plate 1. A cover plate 17 is detachably installed on the other end of the box 16. The drive motor 11, the push mechanism 8, and the gear are all placed inside the box 16, which can protect the gear and the drive motor 11. When it is necessary to lubricate the gear, the cover plate 17 can be opened for operation.

[0035] Furthermore, such as Figure 1 As shown, when the material is placed in the hopper, a first guide plate 15 is inclined at both ends above the two support plates 1. The top of the first guide plate 15 is fixed to the support plate 1, and a second guide plate 14 is inclined on both sides between the two first guide plates 15. The end of the second guide plate 14 is fixed to the first guide plate 15. The material will be poured in between the guide plates. Under the guidance of the guide plates, the material can fall fully and concentratedly between the middle of the two pressure rollers 5. This can fully squeeze the material and prevent the material from falling at the end of the pressure rollers 5, which would cause resistance to the rotation of the pressure rollers 5.

[0036] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods. As long as they can achieve their beneficial effects, they can be implemented. Therefore, this embodiment will not elaborate on their specific structural composition and working principle.

[0037] 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 alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
