Description

Technical Field

[0001] This utility model belongs to the field of feed processing technology, and in particular relates to a cutting device that can be used for pellet feed processing. Background Technology

[0002] Pelleted feed processing involves a series of key steps, namely, batching, cutting, crushing, mixing, conditioning, pelleting, cooling, screening, and packaging. In the batching stage, according to the formula requirements, various raw materials in the batching silo are weighed and transported to the powdering silo. The quality of the batching stage directly affects the batching accuracy of the product. In the crushing stage, the raw materials in the powdering silo are crushed. This is to accurately control the size and particle size of the feed pellets. The working efficiency of the crusher has a direct impact on the production capacity of feed machinery and equipment, and the crushing process has the highest energy consumption in the entire feed production process.

[0003] In the pellet feed processing flow, the relevant raw materials need to be cut in order to facilitate the subsequent crushing work. However, the traditional guillotine is fixed and only has a single cutting function, resulting in low cutting efficiency. During the cutting operation, dust is easily generated, polluting the working environment. Furthermore, fine raw materials are sucked up during dust removal and cannot be effectively collected, causing waste of raw materials. Inconvenient unloading will affect the subsequent transportation of raw materials after cutting, leading to a reduction in the overall efficiency of feed production. Utility Model Content

[0004] The purpose of this invention is to provide a cutting device that can be used in pellet feed processing. This invention addresses the problems in the prior art where the guillotine is fixed and only has a single cutting function, resulting in low cutting efficiency, dust pollution during cutting operations, and the inability to effectively collect fine raw materials during dust removal, leading to material waste.

[0009] The present invention is further configured such that: guide rails are fixedly connected to both side walls of the pre-cutting box; guide blocks are fixedly connected to both inner walls of the gantry frame; the guide blocks are slidably connected to the guide rails; a stepper motor is installed on one outer wall of the gantry frame; the output end of the stepper motor passes through the side arm and guide block of the gantry frame and is fixedly connected to a third gear; a rack is meshed on the periphery of the third gear; the non-tooth surface of the rack is fixedly connected inside a guide rail; a rotating wheel is rotatably arranged inside another guide rail; the rotating wheel and the corresponding guide block are connected by a rotating shaft.

The inspection door is located above the second mesh plate, and the cleaning door is located close to the bottom of the collecting cylinder.

[0012] This utility model has the following beneficial effects: 1. This utility model involves opening the pre-cutting box door to place raw materials, closing the door, starting a stepper motor, and using gears, racks, and other components to move the gantry frame towards the box door. After reaching a suitable interval, the stepper motor intermittently shuts off to achieve self-locking and limit, sealing the chute. A hydraulic cylinder is then activated to drive the guillotine to cut the raw materials. After retraction, the stepper motor continues to move, repeating this process for pre-cutting. Simultaneously, the movement distance of each segment of the sealed pre-cutting component can be controlled by controlling the stepper motor, thereby controlling the size of the cut segments. During the final cut, the guillotine retracts slightly to prevent damage to the blade head. Afterward, the guillotine returns to its initial position, pushing the pre-cut raw materials into the cutting tank. Pre-cutting can initially process larger pieces of feed raw materials into suitable sizes, preparing for subsequent fine cutting, improving overall cutting efficiency. Controlling the size of the cut segments can meet the different feed processing requirements for raw material size, preventing damage to the blade head during guillotine movement, extending the guillotine's service life, and reducing equipment maintenance costs. The guillotine not only cuts but also pushes the pre-cut raw materials into the cutting tank when it resets.

[0013] 2. When the dust removal component of this utility model starts working during the cutting of raw materials in the cutting tank, dust and fine raw materials sequentially enter the collection cylinder through the reducing pipe, the first screen plate, the suction pipe, and the dust inlet. Since the dust inlet extends in the tangential direction of the collection cylinder, the incoming dust and fine raw materials flow along the side wall of the collection cylinder to form a vortex. Under centrifugal force, the fine raw materials separate from the gas. The gas, carrying a small amount of dust and raw materials, flows back upward under the negative pressure at the center of the vortex and passes through the second screen plate of the collection cylinder. The second screen plate filters out the raw materials, and the gas is discharged to the dust collection equipment through the suction pipe. The raw materials entering the collection cylinder are cleaned out through the cleaning door. The suction pipe can be used to backflush and clean the second screen plate. The maintenance door hinged on the periphery of the collection cylinder can be used to further clean the second screen plate to improve the filtration effect. This effectively collects the dust and fine raw materials generated during the cutting process, preventing them from spreading into the working environment, improving the quality of the working environment, protecting the health of the staff, and avoiding unnecessary waste of raw materials.

[0014] 3. When the collection bin is full of cut raw materials, the motor is turned off and the electric push rod is started. Through the connection with the second hinge seat, the right discharge door is rotated and opened. Because the first gear and the second gear set on opposite sides of the collection bin mesh and are fixedly connected to the left discharge door and the right discharge door respectively, the rotation of the right discharge door drives the left discharge door to rotate, and the bottom of the collection bin opens to let the cut raw materials fall out. Then the electric push rod is started to close the left discharge door and the right discharge door. The centralized collection and unloading improves the production efficiency. After cutting, it is convenient to transport the cut raw materials, thereby improving the overall efficiency of feed production.

The circumferential side of the collection cylinder 501 is provided with a dust inlet 502 along the tangential direction. Since the extension direction of the dust inlet 502 is the tangential direction of the collection cylinder 501, the dust and fine materials entering the collection cylinder 501 can flow along the side wall of the collection cylinder 501 and form a vortex. The dust and fine materials in the gas will rotate with the gas. The top center of the collection cylinder 501 is fixedly connected to a suction pipe 503, which is connected to a dust collection device. The suction pipe 503 and the inner cavity of the collection cylinder 501 are connected.

The groove 201 can be sealed by the elastic expansion and contraction of the first folding sealing plate 203 and the second folding sealing plate 204.

[0023] In this embodiment of the present invention, such as Figure 2 and Figure 4As shown, the dust removal assembly 5 also includes a reducing pipe 504.

[0024] In this embodiment of the present invention, such as Figure 1 and Figure 4 As shown, a support frame 7 for supporting the machine housing 1 is provided at the bottom of the machine housing 1. A shaft 301 is rotatably provided inside the cutting tank 3. A motor frame 8 is fixedly connected to one side of the support frame 7. A motor 302 is fixedly connected to the top of the motor frame 8. A drive sprocket 303 is fixedly connected to the output end of the motor 302.

The drive sprocket 303 and the driven sprocket 304 are connected by a chain 305. Several cutting blades 306 are fixedly connected to the circumferential side of the shaft 301.

[0025] In this embodiment of the present invention, such as Figure 5 and Figure 6 As shown, guide rails 605 are fixedly connected to both side walls of the pre-cutting box 2, and guide blocks 606 are fixedly connected to both inner walls of the gantry frame 601. The guide blocks 606 are slidably connected to the guide rails 605. A stepper motor 610 is installed on one outer wall of the gantry frame 601. The output end of the stepper motor 610 passes through the side arm of the gantry frame 601 and the guide block 606 and is fixedly connected to a third gear 607. A rack 608 is meshed on the periphery of the third gear 607. The non-tooth surface of the rack 608 is fixedly connected inside one guide rail 605. A rotating wheel 609 is rotatably installed inside the other guide rail 605.

By controlling the stepper motor 610, the movement distance of each segment of the sealed pre-cutting component 6 can be controlled, thereby controlling the size of the cutting segment.

[0026] In this embodiment of the present invention, such as Figure 1 and Figure 2As shown, the unloading assembly 4 includes a collection bin 401, which is fixedly connected to the bottom slot of the cutting tank 3. An arc-shaped mesh plate 402 is installed at the bottom slot of the cutting tank 3 to allow raw materials cut to a suitable size to fall into the collection bin 401 through its mesh. A first gear 403 and a second gear 404 are connected to opposite sides of the collection bin 401 via rotating shafts. The first gear 403 and the second gear 404 mesh with each other. A left unloading door 405 and a right unloading door 406 are provided at the bottom of the collection bin 401. The left unloading door 405 is fixed between the rotating shafts corresponding to the first gear 403, and the right unloading door 406... Door 406 is fixed between the rotating shafts corresponding to the second gear 404. The first gear 403 is fixedly connected to the left unloading door 405, and the second gear 404 is fixedly connected to the right unloading door 406. A first hinge seat 407 is fixedly connected to one side of the collection bin 401, and a second hinge seat 408 is fixedly connected to one end of the right unloading door 406. An electric push rod 409 is hinged on the first hinge seat 407. The output end of the electric push rod 409 is hinged to the second hinge seat 408. When the right unloading door 406 rotates, it can drive the left unloading door 405 to rotate. The bottom of the collection bin 401 opens, and the cut raw materials fall out to complete the unloading.

[0027] In this embodiment of the present invention, such as Figure 1 and Figure 5 As shown, a door 9 is hinged to one side of the pre-cutting box 2, and an inspection cover 10 is hinged to one side of the cutting tank 3. The arc-shaped mesh plate 402 can be cleaned by opening the inspection cover 10 to prevent clogging. An inspection door 11 and a cleaning door 12 are respectively hinged to two openings on the periphery of the collection cylinder 501. The inspection door 11 is set to further clean the second mesh plate 508 to improve the filtration effect. The raw materials entering the collection cylinder 501 will be cleaned out and reused through the cleaning door 12. The inspection door 11 is set above the second mesh plate 508, and the cleaning door 12 is set close to the bottom of the collection cylinder 501.

[0028] The working principle of this embodiment is as follows: During operation, firstly, the door 9 of the pre-cutting box 2 is opened, then the feed raw materials to be cut are placed inside the pre-cutting box 2, and the door 9 is closed. At this time, the sealed pre-cutting assembly 6 is located at the end of the pre-cutting box 2 away from the door 9. Then, the stepper motor 610 on one side of the gantry frame 601 is started. Because the third gear 607 meshes with the rack 608 fixed inside the guide rail 605, the groove of the guide block 606 slides with the convex rail of the guide rail 605. A rotating wheel 609 is rotatably arranged inside the guide rail 605 on the other side. The rotating wheel 609 is connected to the other side of the gantry frame 601 by a shaft. Therefore, the stepper motor 610 drives the third gear 607 fixedly connected to the output end to rotate, thereby driving the rotating wheel 609 to rotate on the other side of the guide rail 601. The stepper motor 610 rotates internally, thereby moving the gantry frame 601 towards the door 9. When a suitable interval is reached, the stepper motor 610 is intermittently shut off. At this time, by shutting off the stepper motor 610, the stepper motor 610 limits the sealing pre-cutting component 6 through its own self-locking. The first folding sealing plate 203 and the second folding sealing plate 204 are both slidably connected to the slots on both sides of the slide 201. The slide 201 can be sealed by the elastic expansion and contraction of the first folding sealing plate 203 and the second folding sealing plate 204. Then, the hydraulic cylinder 602 is started, and the output end of the hydraulic cylinder 602 moves downward, thereby moving the guillotine 604 downward to cut the feed raw materials. The output end of the hydraulic cylinder 602 retracts, thereby moving the guillotine 604 back. Then, the stepper motor is started again. The stepper motor 610 moves segment by segment, repeating this process to pre-cut the raw material. The stepper motor 610 controls the movement distance of each segment of the sealed pre-cutting assembly 6, thus controlling the size of the cut segment. When the final cut is completed, the guillotine 604 retracts slightly (the distance between the guillotine 604's blade tip and the bottom of the pre-cutting box should be less than the diameter of the raw material's cut surface), allowing the blade tip to move away from the bottom of the pre-cutting box 2 to prevent damage during movement. The stepper motor 610 is restarted, and as the guillotine 604 returns to its initial position, the pre-cut raw material is pushed into the cutting tank 3. The hydraulic cylinder 602 is activated, and the guillotine 604 rises to its initial position. Then, the motor 302 is started, driving the drive sprocket 303 to rotate. Because the drive sprocket 303 and the driven sprocket 304 are connected by a chain 3... The 05 connection causes the driven sprocket 304 to rotate, which in turn drives the shaft 301 to rotate, causing the cutting blade 306 to rotate at high speed to cut the raw material. The raw material cut into suitable sizes falls into the collection bin 401 through the mesh of the arc-shaped mesh plate 402. A maintenance cover 10 is hinged to one side of the opening of the cutting tank 3. By opening the maintenance cover 10, the arc-shaped mesh plate 402 can be cleaned to prevent blockage. While the raw material is being cut in the cutting tank 3, the dust removal component 5 starts to work. The suction pipe 503 is connected to a dust collection device. The dust and fine raw materials generated by high-speed cutting pass through the reducing pipe 504, the first mesh plate 507, the suction pipe 505, and the dust inlet 502 in sequence. When the dust and fine raw materials enter the collection cylinder 501 from the dust inlet 502 at a certain speed...Since the extension direction of the dust inlet 502 is tangential to the collecting cylinder 501, the dust and fine materials entering the collecting cylinder 501 can flow along the side wall of the collecting cylinder 501 and form a vortex. The dust and fine materials in the gas will rotate with the gas. Under centrifugal force, the fine materials will adhere tightly to the side wall of the collecting cylinder 501, thereby separating the fine materials from the gas. The gas, carrying a small portion of fine materials and dust, will flow back upward under the negative pressure generated at the center of the vortex and pass through the second screen plate 508 of the collecting cylinder 501. The second screen plate 508 filters out the material, and the gas is discharged to the dust collection equipment through the suction pipe 503. The material entering the collecting cylinder 501 is finally cleaned out through the cleaning door 12 hinged to the periphery of the collecting cylinder 501. The suction pipe 503 can also be used to backflush the second screen plate 508 to achieve a cleaning effect. The collecting cylinder 501 has an inspection door 11 hinged to the periphery for further cleaning of the second screen plate 508 to improve the filtration effect. When the hopper 401 is full of cut raw materials, the motor 302 is turned off, and the electric push rod 409 is started. The output end of the electric push rod 409 is hinged to the second hinge seat 408, which is fixedly connected to one end of the right discharge door 406. The retraction of the output end of the electric push rod 409 can drive the right discharge door 406 to rotate and open. The hopper 401 is rotatably equipped with a first gear 403 and a second gear 404 on both sides. The first gear 403 and the second gear 404 mesh with each other. 3 is fixedly connected to the left discharge door 405, and the second gear 404 is fixedly connected to the right discharge door 406. Therefore, rotating the right discharge door 406 can drive the left discharge door 405 to rotate, opening the bottom of the collection bin 401, allowing the cut raw materials to fall out and complete the unloading. Then, by activating the electric push rod 409, the left discharge door 405 and the right discharge door 406 are closed, and the box door 9 of the pre-cutting box 2 is opened again. The feed raw materials to be cut are placed inside the pre-cutting box 2, and the box door 9 is closed. This process is repeated to perform the cutting operation.
