Description

Technical Field

[0001] This invention relates to a cold pelleting device, specifically a cold pelleting device for pellet feed equipped with a handling robot, belonging to the field of pellet feed production technology. Background Technology

[0002] Pelleted feed is a specially processed animal feed that provides animals with the necessary nutrients more effectively, promoting healthy growth. Pelleted feed is characterized by its more stable nutritional composition, which is easier for animals to absorb and digest, significantly improving feeding efficiency. Cold pelleting is a technology that compresses feed ingredients into pellets at low temperatures, effectively avoiding and reducing the effects of high temperatures while preserving protein, vitamins, and other nutrients. Cold-formed pellets are more robust, can withstand certain mechanical impacts, and are less prone to moisture absorption and clumping, reducing breakage losses during transportation and storage, and facilitating long-term storage and long-distance transport.

[0003] According to patent CN111904010A, a cold pellet mill for microbial fermentation feed is disclosed, which includes a processing box. The processing box is divided into a sterilization chamber and an inoculation chamber by a partition. The sterilization chamber and the inoculation chamber are arranged side by side. A feeding pipe communicating with the sterilization chamber is provided on the side wall of the processing box. A conveyor belt drives the sterilization chamber and the inoculation chamber.

[0004] The above-mentioned solution can effectively avoid contamination of microbial fermentation by external pollutants, improve the quality of feed fermentation, and enable the reuse of bacterial liquid. However, in the process of raw material mixing, the above-mentioned solution only uses a rotating stirring rod to stir the raw materials in one direction, resulting in a relatively poor mixing effect, which affects the final production quality of the product. In addition, the processing and pelleting efficiency of the device is low, making it difficult to meet the needs of industrial production. Therefore, we provide a pellet feed cold pelleting device with a handling robot to solve the above problems. Summary of the Invention

[0008] Preferably, two sets of support rods are fixedly connected to the outer surface of the transmission gearbox, and each support rod is fixedly connected to the cold granulation tank. The support rods play a role in stabilizing and supporting the operation of the transmission gearbox.

[0009] Preferably, each of the sliding top rods has a ball bearing movably mounted at its bottom end.

A connecting frame two is fixedly connected inside the sliding track, and the bottom end of the driven rod is rotatably connected to the connecting frame two.

Each support plate is fixedly connected to the cold granulation tank, and the support plates provide a stable support effect for the use of the extrusion molding box.

[0012] Preferably, the bottom end of the extrusion molding box is fixedly connected to a feeding channel, which passes through the cold pelleting tank and is fixedly connected to it. The feeding channel serves to discharge feed pellets.

[0016] This invention provides a cold pelleting device for pellet feed with a handling robot, which has the following beneficial effects: This application incorporates components such as a lifting storage plate, a mixing drum, a mixing mechanism, a transmission mechanism, and an extrusion mechanism. The mixing mechanism stirs the materials inside the mixing drum, while the transmission mechanism uses the rotation of the driven rod to drive the lifting storage plate to vibrate while stirring.

[0017] This application, through the arrangement of components such as driven rod, transmission gearbox, stirring rod and sprinkling plate, allows the sprinkling plate to evenly sprinkle materials inside the mixing drum, facilitating uniform mixing of materials by the stirring rod. The arc-shaped rod with a certain curvature design can reduce the resistance encountered by the stirring rod, which helps to improve mixing efficiency, reduce energy consumption, thereby increasing the uniformity of raw material mixing and improving the quality of cold granulation operation.

[0018] This application, through the configuration of components such as driven rollers, sliding top rods, sliding channels, and limiting top blocks, enables the transmission mechanism to drive the lifting storage plate to move up and down and slide inside the cold granulation tank through the rotation of the driven rod. This allows the raw materials in the mixing drum to be affected by the vibration from the lifting storage plate while being stirred, which not only improves the mixing uniformity of the raw materials, but also facilitates the falling of the raw materials through the mesh in the lifting storage plate, further improving the mixing uniformity of the materials by the device.

[0019] This application, through the arrangement of components such as an extrusion molding box, molding roller, extrusion roller, and separating cutter, enables the molding roller and extrusion roller to extrude the material by rotation, and the extruded material to be cut by the separating cutter, thereby completing the extrusion molding operation of feed and improving the production and processing efficiency of the device. The formed feed pellets are then transported to the subsequent cooling and bagging equipment through a collection cylinder and a handling robot, which greatly reduces the time and labor intensity of manual handling and improves the operational efficiency of factory production.

[0022] This invention provides a cold pelleting device for pellet feed equipped with a handling robot.

[0023] See also Figure 1 and Figure 2 The device includes a cold granulation tank 1, which provides stable support for the use and installation of various components. All electrical components and related equipment involved in this application are existing technologies. During installation and use, they should be operated according to actual conditions. The structural diagrams of each component shown in the accompanying drawings are illustrative examples. Their specific real-time operation should be adapted and optimized by combining the functional requirements, assembly conditions and process limitations in the actual application scenario, and adjusting the structural parameters, size specifications and connection methods accordingly.

[0024] A cold air blower 9 is fixedly installed on the outside of the cold pelleting tank 1. An air outlet pipe 10 is fixedly connected to the top of the cold pelleting tank 1. The cold air blower 9 can be an industrial-grade model such as RDF3 or GRNGE. The specific selection depends on the actual usage scenario and cooling requirements. The air outlet of the cold air blower 9 is installed inside the cold pelleting tank 1, between the lifting storage plate 2 and the fixed plate 3. When the cold air blower 9 is running, it can deliver cold air into the cold pelleting tank 1. The cold air will pass through the space between the lifting storage plate 2 and the fixed plate 3 and be discharged along the air outlet pipe 10, thereby removing the heat and moisture carried by the pellet feed raw materials inside the mixing drum 4, completing the cooling effect of the raw materials, which is convenient for the subsequent processing of the raw materials into cold pellets, and is beneficial for the storage and transportation of feed.

[0025] See also Figure 1The cold pelleting tank 1 has a collection cylinder 11 on its exterior. A handling robot 12 for moving the collection cylinder 11 is fixedly installed on the exterior of the cold pelleting tank 1. A controller 14 is fixedly installed on the outer surface of the cold pelleting tank 1. The collection cylinder 11 is used to receive the cold pelleted feed discharged from the cold pelleting tank 1. The handling robot 12 can automatically move the collection cylinder 11 and place the feed in the collection cylinder 11 to a designated position, which facilitates the cooling and bagging of the pelleted feed in the collection cylinder 11. This greatly reduces the time and labor intensity of manual handling and improves production efficiency. The collection cylinder 11 can be replaced with a disc-shaped or other shaped receiving device according to actual needs. The handling robot 12 adopts the SDL-2000iC / 165F model, which has the advantages of precise handling and placement, improving the accuracy of the production process. The controller 14 is a commonly used factory device that can control the operation of various electrical components in the device through parameter settings, thereby facilitating the automated processing of cold pelleted feed.

[0026] See Figure 2 , Figure 3 , Figure 4 and Figure 5 The cold pelleting tank 1 is internally connected to a lifting storage plate 2, and the top surface of the lifting storage plate 2 is fixedly connected to a stirring drum 4. The stirring drum 4 is internally equipped with a stirring mechanism 5. The lifting storage plate 2 has a mesh opening in the middle, which allows the feed raw materials in the stirring drum 4 to fall at a specific speed after being stirred by the stirring mechanism 5. The stirring drum 4 can store the feed raw materials, which facilitates the stirring mechanism 5 to stir the raw materials, improves the mixing uniformity of the raw materials, and helps to improve the quality of the cold pelleting operation. The lifting storage plate 2 is slidably connected to the driven rod 503, which facilitates the lifting storage plate 2 to rise and vibrate under the action of the transmission mechanism 6, thereby further improving the mixing uniformity of the raw materials by the device.

[0027] See also Figure 2 , Figure 3 and Figure 4 The stirring mechanism 5 includes a transmission gearbox 501. The input and output ends of the transmission gearbox 501 are respectively fixedly connected to a drive rod 502 and a driven rod 503. A servo motor 508 is fixedly installed on the outside of the cold granulation tank 1. The drive rod 502 is fixedly connected to the output shaft of the servo motor 508. When the servo motor 508 starts, it can drive the drive rod 502 to rotate. The rotation of the drive rod 502 can drive the driven rod 503 to rotate through the transmission gearbox 501, thereby providing power for the operation of the stirring mechanism 5 and the stirring drum 4. The transmission gearbox 501 adopts models such as BS45T-001 or BS65T-001, which can realize the transmission and steering of power. The transmission gearbox 501 is completely enclosed, with dustproof and safety protection functions.

[0028] An arc-shaped rod 504 is fixedly connected to the outer surface of the driven rod 503. A set of stirring rods 505 is fixedly connected to the bottom surface of the arc-shaped rod 504. When the driven rod 503 rotates, the arc-shaped rod 504 also rotates, driving the stirring rods 505 to rotate inside the mixing drum 4. This allows the stirring rods 505 to stir the feed ingredients in the mixing drum 4. The arc-shaped rod 504 has a certain curvature design, which can reduce the resistance encountered by the stirring rods 505 during stirring, thus helping to improve stirring efficiency and reduce energy consumption.

[0029] A sprinkling plate 506 is fixedly connected to the top of the driven rod 503. A feed pipe 13 is fixedly connected to the top surface of the cold pelleting tank 1. Two sets of support rods 507 are fixedly connected to the outer surface of the transmission gearbox 501. Each support rod 507 is fixedly connected to the cold pelleting tank 1. The feed pipe 13 includes a feed inlet located above the cold pelleting tank 1 and a conveying pipe rotatably installed inside the cold pelleting tank 1. Workers can use existing equipment such as conveyor belts and augers to transport feed raw materials and auxiliary materials into the feed pipe 13 to reduce the workload of workers handling materials. When the feed raw materials enter the cold pelleting tank 1 through the feed pipe 13, the sprinkling plate 506 can rotate and evenly sprinkle the raw materials and auxiliary materials into the mixing drum 4 under the rotation of the driven rod 503, thereby facilitating the improvement of the mixing uniformity of raw materials and auxiliary materials. The support rods 507 can provide a stable support effect for the installation and use of the transmission gearbox 501, improving the stability of the mixing mechanism 5.

[0030] See also Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 A fixed plate 3 is fixedly connected to the inner wall of the cold granulation tank 1. A transmission mechanism 6 is provided between the lifting storage plate 2 and the fixed plate 3. The transmission mechanism 6 includes a driven wheel 601. When the stirring mechanism 5 is stirring and mixing the raw materials in the stirring drum 4, the transmission mechanism 6 can drive the lifting storage plate 2 to move up and down inside the cold granulation tank 1 through the rotation of the driven rod 503. This allows the raw materials in the stirring drum 4 to be affected by the vibration from the lifting storage plate 2 while being stirred, which not only improves the mixing uniformity of the raw materials, but also facilitates the falling of the raw materials through the mesh in the lifting storage plate 2.

[0031] A set of sliding push rods 602 are slidably connected inside the driven rotary wheel 601. Each sliding push rod 602 has a ball bearing 605 movably mounted at its bottom end. A sliding track 603 is fixedly connected to the inner wall of the fixed plate 3. A set of limiting blocks 604 are fixedly connected to the top surface of the sliding track 603. The bottom ends of the sliding push rods 602 are slidably connected to the sliding track 603 and the limiting blocks 604. The ball bearings 605 significantly reduce the friction experienced by the bottom end of the sliding push rods 602, reducing wear and extending the service life of the device. The bottom surface of the lifting storage plate 2 has an opening adapted to the top end of the sliding push rods 602. The slide groove, the slide channel 603 and the top surface of the limiting block 604 are provided with a slide groove that is adapted to the ball 605. When the driven wheel 601 rotates and drives the sliding rod 602 to move, the ball 605 will move along the slide groove. When the ball 605 passes the limiting block 604, since the limiting block 604 has a certain degree of protrusion, the sliding rod 602 will rise and fall along the protrusion of the limiting block 604, thereby pushing the lifting storage plate 2 to slide and rise inside the cold granulation tank 1. Through the setting of multiple sliding rods 602 and limiting blocks 604, the support stability of the lifting storage plate 2 can be guaranteed.

[0032] A connecting frame 606 is fixedly connected inside the driven wheel 601. The driven rod 503 is fixedly connected to the connecting frame 606. A connecting frame 607 is fixedly connected inside the sliding track 603. The bottom end of the driven rod 503 is rotatably connected to the connecting frame 607. When the driven rod 503 rotates, it can drive the driven wheel 601 to rotate. The rotation of the driven wheel 601 can drive several sliding top rods 602 inside it to move accordingly, thereby driving the lifting storage plate 2 to vibrate with a certain amplitude and frequency, which facilitates the mixing effect of the stirring mechanism 5 on the raw materials. The connecting frame 607 provides a limiting and supporting effect for the rotation of the driven rod 503, improving the stability of the driven rod 503 in use.

[0033] See also Figure 2 , Figure 3 , Figure 8 , Figure 9 , Figure 10 and Figure 11Below the fixed plate 3, an extrusion mechanism 7 is provided. The extrusion mechanism 7 includes an extrusion molding box 701. The bottom end of the fixed plate 3 is fixedly connected to a feeding pipe 8. The end of the feeding pipe 8 passes through the extrusion molding box 701 and is fixedly connected to the extrusion molding box 701. A set of support plates 708 are fixedly connected to the outer surface of the extrusion molding box 701. Each support plate 708 is fixedly connected to the cold granulation tank 1. The support plates 708 are distributed at multiple positions on the outer surface of the extrusion molding box 701, which can provide stable support for the use of the extrusion molding box 701. When the material that has been uniformly stirred, mixed and cooled by cold air falls into the fixed plate 3, it will enter the extrusion molding box 701 along the feeding pipe 8. The extrusion mechanism 7 can extrude and mold the raw material. The extrusion molding box 701 provides support for the extrusion operation of the extrusion mechanism 7. The feeding pipe 8 has a certain inclination angle, which can ensure that the material automatically slides into the interior of the extrusion molding box 701 under the action of gravity.

[0034] The inner wall of the extrusion molding box 701 is rotatably connected to the molding roller 702, and the outer surface of the extrusion molding box 701 is fixedly mounted with a servo motor 710. The output shaft of the servo motor 710 is fixedly connected to the molding roller 702. When the servo motor 710 is started, it can drive the molding roller 702 to rotate inside the extrusion molding box 701. The molding roller 702 has extrusion holes of a specified shape and size. The shape should be determined according to the actual needs of pellet feed preparation. The servo motor 710 provides power for the rotation of the molding roller 702 and the extrusion roller 703. The servo motor 710 and the servo motor 508 are both prior art, and will not be described in detail in this application.

[0035] Two extrusion rollers 703 are rotatably connected to the inner wall of the extrusion molding box 701. Two separating cutters 704 are fixedly connected to the inner wall of the extrusion molding box 701. A guide plate 707 is fixedly connected to the inner wall of the extrusion molding box 701. The guide plate 707 has a certain inclination angle to facilitate material conveying. When the material enters the extrusion molding box 701 through the feeding pipe 8, it will be conveyed to the outside of the extrusion rollers 703 under the action of the guide plate 707. Since there is a certain speed difference between the forming roller 702 and the extrusion roller 703, when the forming roller 702 and the extrusion roller 703 are in motion, the material will move towards the outside of the extrusion rollers 703. While the roller 703 is rotating, the material is extruded through the extrusion hole and formed by the extrusion roller 702 under the pressure of the extrusion roller 703. At this time, the separating cutter 704 cuts the extruded material, thereby completing the extrusion forming operation of the feed. There is no high temperature during the operation, which can retain the nutritional components of the raw material to the maximum extent. After the material falling off the edge of the extrusion roller 703 accumulates to a certain amount, it will be squeezed by another extrusion roller 703, and then cut into shape by the separating cutter 704 on the other side, which helps to improve the extrusion forming efficiency of the extrusion mechanism 7.

[0036] A drive gear 705 is fixedly connected to the end of the forming roller 702, and a driven internal gear 706 is fixedly connected to the end of each extrusion roller 703. Each driven internal gear 706 meshes with the drive gear 705. Since there is a certain difference between the number of teeth of the drive gear 705 and the number of driven internal gears 706, there is a certain difference in the rotation speed of the drive gear 705 and the driven internal gears 706. When the forming roller 702 drives the drive gear 705 to rotate inside the extrusion forming box 701, the drive gear 705 can drive the two driven internal gears 706 to rotate synchronously. The rotation of the driven internal gears 706 can drive the extrusion roller 703 to rotate synchronously, thereby enabling the extrusion roller 703 to extrude the material.

[0037] See also Figure 1 , Figure 2 , Figure 3 and Figure 8 The bottom end of the extrusion molding box 701 is fixedly connected to the feeding channel 709. The feeding channel 709 passes through the cold pelleting tank 1 and is fixedly connected to the cold pelleting tank 1. The feeding channel 709 has a certain inclination angle, which facilitates the discharge of the cold-pressed feed pellets in the extrusion molding box 701 from the cold pelleting tank 1. The bottom end of the feeding channel 709 is slightly higher than the top end of the collecting cylinder 11, so as to ensure that the processed cold pellets of feed can be discharged into the collecting cylinder 11 without obstructing the handling robot 12 from handling the collecting cylinder 11, which greatly improves the operation efficiency of automated pellet feed production.

[0038] Working Principle: During operation, the operator first starts the device and adds feed ingredients and auxiliary materials to the cold pelleting tank 1 via the feed pipe 13. The servo motor 508 starts, driving the driven rod 503 to rotate via the transmission gearbox 501. The rotation of the driven rod 503 drives the arc rod 504, stirring rod 505, and sprinkling plate 506 to rotate, resulting in the sprinkling plate 506 evenly sprinkling the material and the stirring rod 505 mixing the material, improving the mixing uniformity. The rotation of the driven rod 503 also drives the driven rotor 601 to rotate, which in turn moves the sliding top rod 602. The limiting block 604 limits the movement of the sliding top rod 602 to a certain extent, allowing it to continuously lift the lifting storage plate 2 during its movement. This causes the lifting storage plate 2 to vibrate and mix the internal material, further improving the mixing uniformity. While mixing, the air cooler 9 starts and delivers cold air into the cold pelleting tank 1 to reduce the heat and moisture carried by the material, which is beneficial to improving feed quality. The mixed material enters the extrusion molding box 701 through the feeding pipe 8. The servo motor 710 starts and drives the molding roller 702 to rotate. The rotation of the molding roller 702 drives the extrusion roller 703 to rotate inside the molding roller 702 through the drive gear 705 and the driven internal gear 706. As a result, the material overflows from the extrusion hole under the extrusion of the molding roller 702 and the extrusion roller 703, and falls into the feeding channel 709 under the cutting of the separating cutter 704. The material is then transported to the collection cylinder 11 through the feeding channel 709. After the time set by the program, the handling robot 12 will transport the collection cylinder 11 to the cooling or other subsequent processing equipment to realize the automated cold pelleting processing of pellet feed.
