Description

Technical Field

[0001] This utility model relates to the field of cutter shaft technology, specifically a cutter shaft mechanism for a feed pellet mill. Background Technology

[0002] A feed pellet mill is a key piece of equipment that mechanically extrudes powdered feed ingredients into pellets, and it is widely used in livestock and poultry farming, aquatic feed, and biomass energy. Its core working components include a ring die, pressure rollers, and a cutting mechanism. The cutting mechanism is responsible for cutting the extruded strips of feed into pellets of a specified length, directly affecting the uniformity of the pellets and production efficiency. Traditional cutting mechanisms usually use fixed blades or a single-blade structure, and the cutting function is achieved through mechanical or hydraulic adjustment.

[0003] However, because the cutter is in contact with the high-speed rotating ring die for a long time, continuous operation of a single cutter can easily lead to rapid wear of the cutter head, or even deformation or breakage due to friction and high temperature, affecting the cutting quality and increasing maintenance costs. Therefore, a cutter shaft mechanism for feed pellet mills is needed to solve the existing shortcomings. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of existing single cutters that are prone to wear during continuous operation.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a cutter shaft mechanism for a feed pellet mill, comprising a mounting frame, a mounting plate movably connected to the bottom of the mounting frame via a rotating shaft, cutters fixedly connected to both ends of the bottom of the mounting plate via bolts, a set of symmetrical control plates movably connected to the top of the mounting plate via a rotating shaft, and the mounting frame being located on the opposite side of the control plates, an adjustment component movably connected to the mounting frame and connected to the control plates, and a synchronization component provided at the top of the mounting frame and connected to the adjustment component.

[0006] Furthermore, the adjustment assembly includes a rotating rod, a connecting block, and a movable frame. The connecting block is fixedly connected to the inner side of the movable frame. The rotating rod has a thread on its outer side and passes through the connecting block. The rotating rod and the connecting block are threaded together.

[0007] Furthermore, both ends of the movable frame are fixedly connected to sliders, and a set of symmetrical sliding grooves are provided on the inner side of the mounting frame. The movable frame is slidably connected to the inner side of the mounting frame by means of movable cooperation between the sliders and the sliding grooves.

[0008] Furthermore, the adjustment assembly also includes a second rotating rod, a second connecting block, and a second movable frame. The second connecting block is fixedly connected to the inner side of the second movable frame. The outer side of the second rotating rod is threaded. The second rotating rod passes through the second connecting block and is threadedly connected to the second connecting block.

[0009] Furthermore, both ends of the movable frame two are fixedly connected to slider two, and a set of symmetrical sliding grooves two are opened on the inner side of the mounting frame. The movable frame two is slidably connected to the inner side of the mounting frame by means of movable cooperation between slider two and sliding groove two.

[0010] Furthermore, the top of one of the control plates is movably connected to the outer side of the first movable frame via a pivot, and the top of the other control plate is movably connected to the outer side of the second movable frame via a pivot. The tops of both the first and second rotating rods are connected to the inner side of the mounting frame, and the thread direction of the first rotating rod is opposite to that of the second rotating rod.

[0011] Furthermore, the synchronization component includes a chain belt, a first sprocket, and a second sprocket. The first sprocket is symmetrically arranged. The top ends of the first and second sprockets are both fixedly connected to the first sprocket. The chain belt is sleeved on the outside of the first and second sprockets, and the first sprocket, the second sprocket, and the chain belt constitute a chain drive structure.

[0012] Furthermore, the second sprocket is movably connected to the top of the mounting frame via a rotating shaft. A servo motor is fixedly connected to the top of the mounting frame, and the output end of the servo motor is fixedly connected to the end of the rotating shaft of the second sprocket.

[0013] Compared with the prior art, the cutter shaft mechanism of this feed pellet mill has the following advantages:

[0014] I. This utility model, through the setting of the adjustment component, allows the mounting plate to rotate around its axis, thereby controlling the end of one of the cutters to approach the outer side of the ring die, thus cutting the feed off the ring die. By alternating the use of the cutters, the wear of the cutter head caused by continuous use of a single cutter and the rise in cutter temperature during the cutting process, which would cause damage to the cutter itself, are avoided, thereby improving the durability of the entire cutter shaft mechanism.

[0015] Second, this utility model uses a synchronization component to start a servo motor, causing the second sprocket inside the mounting frame to rotate. Since the first sprocket, the second sprocket, and the chain belt constitute a chain belt transmission structure, the two first sprockets can rotate synchronously, thus achieving synchronous rotation of the first and second rotating rods. This is beneficial for controlling the first and second moving frames to move synchronously in opposite directions, thereby enabling the angle adjustment of the mounting plate.

[0021] 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.

[0022] like Figure 1-4 As shown, this utility model provides a technical solution: a cutter shaft mechanism for a feed pellet mill, including a mounting frame 1. The bottom of the mounting frame 1 is movably connected to a mounting plate 2 via a rotating shaft. Both ends of the bottom of the mounting plate 2 are fixedly connected to cutters 3 via bolts. The top of the mounting plate 2 is movably connected to a set of symmetrical control plates 4 via a rotating shaft, and the mounting frame 1 is located on the opposite side of the control plates 4. An adjustment component 5 is movably connected to the mounting frame 1, and the adjustment component 5 is connected to the control plates 4. A synchronization component 6 is provided on the top of the mounting frame 1, and the synchronization component 6 is connected to the adjustment component 5. First, the entire device is fixedly connected to the inside of the feed pellet mill via the mounting frame 1, which is a conventional installation scheme, and the entire device is located on one side of the ring die.

[0023] like Figure 1 and Figure 3As shown, the adjustment assembly 5 includes a rotating rod 501, a connecting block 502, and a movable frame 503. The connecting block 502 is fixedly connected to the inner side of the movable frame 503. The rotating rod 501 has a thread on its outer side and passes through the connecting block 502, and the rotating rod 501 is threaded to the connecting block 502. Both ends of the movable frame 503 are fixedly connected to sliders 7. The inner side of the mounting frame 1 has a set of symmetrical sliding grooves 8. The movable frame 503 is slidably connected to the inner side of the mounting frame 1 by the movable engagement of sliders 7 and sliding grooves 8. The adjustment assembly 5 also includes a rotating rod 504, a connecting block 505, and a movable frame 506. The connecting block 505 is fixedly connected to the inner side of the movable frame 506, and the rotating rod 504... The outer side of the frame is threaded, the second rotating rod 504 passes through the second connecting block 505, and the second rotating rod 504 is threadedly connected to the second connecting block 505. Both ends of the second moving frame 506 are fixedly connected to the second slider 9. The inner side of the mounting frame 1 is provided with a set of symmetrical sliding grooves 10. The second moving frame 506 is slidably connected to the inner side of the mounting frame 1 by the sliding cooperation of the second slider 9 and the second sliding groove 10. The top of one control plate 4 is movably connected to the outer side of the first moving frame 503 through a rotating shaft, and the top of the other control plate 4 is movably connected to the outer side of the second moving frame 506 through a rotating shaft. The top of the first rotating rod 501 and the top of the second rotating rod 504 are both connected to the inner side of the mounting frame 1, and the thread direction of the first rotating rod 501 is opposite to the thread direction of the second rotating rod 504.

[0024] By connecting the rotating rod with the connecting block through a threaded engagement, and by restricting the movement direction of the moving frame by the mounting frame 1, the rotating rod rotates, causing the moving frame to move longitudinally along the inner side of the mounting frame 1. This allows the control plate 4 connected to the moving frame to rotate. Since the rotation directions of the threads of the rotating rod 1 501 and the rotating rod 2 504 are different, the moving frames 1 503 and 2 506 move in opposite directions. When the moving frame 1 503 moves upward, the moving frame 2 506 moves downward, causing the control plates 4 on their respective sides to rotate. This allows the mounting plate 2 to rotate around its axis, thereby controlling the end of one of the cutters 3 to approach the outer side of the ring die, thus cutting the feed off the ring die. By alternating the use of the cutters 3, the wear of the cutter head and the temperature rise of the cutter 3 during the cutting process, which would otherwise cause damage to the cutter 3 due to continuous use of a single cutter 3, are avoided. This improves the durability of the entire cutter shaft mechanism.

[0025] like Figure 1 and Figure 4As shown, the synchronization component 6 includes a chain belt 601, a first sprocket 602, and a second sprocket 603. The first sprocket 602 is symmetrically arranged. The top ends of the first rotating rod 501 and the second rotating rod 504 are both fixedly connected to the first sprocket 602. The chain belt 601 is sleeved on the outside of the first sprocket 602 and the second sprocket 603. The first sprocket 602, the second sprocket 603, and the chain belt 601 constitute a chain drive structure. The second sprocket 603 is movably connected to the top of the mounting frame 1 through a rotating shaft. The top of the mounting frame 1 is fixedly connected to a servo motor 11, and the output end of the servo motor 11 is fixedly connected to the end of the rotating shaft of the second sprocket 603.

[0026] Start the servo motor 11 to make the second sprocket 603 inside the mounting frame 1 rotate. Since the first sprocket 602, the second sprocket 603 and the chain belt 601 constitute the chain belt 601 transmission structure, the two first sprockets 602 can rotate synchronously, realizing the synchronous rotation of the first rotating rod 501 and the second rotating rod 504. This is beneficial to control the first moving frame 503 and the second moving frame 506 to move synchronously in opposite directions, so as to realize the angle adjustment of the mounting plate 2.

[0027] Working principle: During use, the servo motor 11 is started, causing the second sprocket 603 inside the mounting frame 1 to rotate. Since the first sprocket 602, the second sprocket 603, and the chain 601 constitute the chain belt 601 transmission structure, the two first sprockets 602 can rotate synchronously, realizing the synchronous rotation of the first rotating rod 501 and the second rotating rod 504. Through the threaded engagement between the rotating rod and the connecting block, and the fact that the mounting frame 1 restricts the movement direction of the moving frame, the rotation of the rotating rod enables the moving frame to move longitudinally along the inner side of the mounting frame 1, thereby achieving... The control plate 4 connected to the movable frame can rotate. Since the screw rotation directions of the first rotating rod 501 and the second rotating rod 504 are different, the first movable frame 503 and the second movable frame 506 move in opposite directions. When the first movable frame 503 moves upward, the second movable frame 506 moves downward, driving the control plate 4 on each side to rotate, so that the mounting plate 2 can rotate around its axis, thereby controlling the end of one of the cutters 3 to approach the outside of the ring die, thereby cutting the feed off the ring die. This is achieved by alternating the use of the cutters 3.

[0028] 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.
