Description

Technical Field

[0001] This invention belongs to the field of conveying equipment technology, and particularly relates to a feed bag conveying device with shaping function. Background Technology

[0002] In the modern feed processing industry, granular or powdered feed is quantitatively filled and sealed to form feed bags with a certain volume and weight. These feed bags usually need to be transported smoothly over long distances by conveyor belts and finally delivered to the palletizing station. Automated palletizing robotic arms complete the grabbing, handling, and stacking operations to facilitate subsequent warehousing or loading logistics. Freshly filled feed packages often have an irregular, bulging shape with a raised center and concave ends. Not only does the interior contain a large amount of unexpelled air, but the feed material is also prone to local accumulation and hardening when falling freely. When these untreated raw feed bags are directly transported to the robotic arms for palletizing via conveyor belts, their irregular shape can cause uneven force on the robotic arm's suction cups or grippers, resulting in grabbing failures. Furthermore, the center of gravity of the stacked material shifts, making it prone to large-scale collapse accidents when left idle in the warehouse or during forklift handling.

[0003] Traditional feed bag shaping devices mostly use simple single-stage heavy-duty pressure plates for direct physical compression. This crushing cannot eliminate the hardened feed clumps that have already formed inside the bag beforehand. Under vertical downward pressure, these internal clumps become stress concentration points, directly puncturing the woven bag from the inside. Static pressure will instantly and drastically compress the volume of air trapped inside the bag, causing the packaging bag to burst due to the sudden increase in internal air pressure. When the feed is subjected to strong vertical compression, the material will flow and spread laterally in all directions, causing the feed to accumulate violently on both sides of the edge. This not only fails to form a regular and flat right angle edge, but also easily causes the side seams of the packaging bag to crack. Summary of the Invention

[0004] The purpose of this invention is to solve the problems of high bag bursting rate and poor shaping geometry caused by internal clumping and puncture, poor air venting and air pockets, and lack of side extension space in traditional feed bag shaping devices during forced flattening. Therefore, this invention proposes a feed bag conveying device with shaping function.

[0009] The side-pulling mechanism includes multiple upper and lower clamping plates respectively located on both sides of the inside of the shaping chamber. The upper and lower clamping plates are arranged in pairs. The opposing movement of the upper and lower clamping plates clamps the side of the feed bag and pulls it outward, providing lateral space for the feed inside the bag to be compressed and stretched.

[0037] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0038] 1. In this invention, by setting up a homogenizing mechanism, multiple synchronous rods drive the oscillating head to perform matrix-like reciprocating impacts on the bottom of the feed bag, which evenly disperses the locally hardened feed clumps inside the bag, improves the fluidity of the feed inside the bag, makes the feed distribution more uniform, and prevents the internal clumps from puncturing the woven bag from the inside due to concentrated force during the subsequent calendering process, thereby reducing the bag breakage rate on the production line.

[0039] 2. In this invention, by setting up a calendering mechanism, while continuously applying vertical pressure during the downward pressing of the feed by the pressure plate, a tangential horizontal guiding force is introduced to guide and expel the gas accumulated inside the bag. This breaks the problem of sudden increase in local air pressure caused by the instantaneous sealing of the air inside the bag, solves the problem of air pocket bursting caused by unidirectional compression, and improves the compaction density and flatness of the feed bag.

[0040] 3. In this invention, by setting up a side-pulling mechanism, the upper and lower clamps accurately capture the side of the feed bag and actively stretch and tighten it outwards, creating sufficient lateral avoidance and extension space for the feed that flows outwards under vertical pressure. This avoids the problem of side seam cracking caused by excessive accumulation of material at the dead corner of the bag opening. In conjunction with the calendering mechanism at the top, the feed bag is forcibly shaped into a standard geometric cuboid, which meets the stacking requirements of the end-effector robotic arm.

[0052] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0053] Please see Figures 1-10 This invention provides a technical solution: a feed bag conveying device with a shaping function, including an input belt 1, a shaping chamber 2 at one end of the input belt 1, an output belt 3 on one side of the shaping chamber 2, and a robotic arm 4 on one side of the output belt 3, and further including:

[0054] The homogenizing mechanism 5 includes multiple oscillating heads 505 located inside the shaping chamber 2. The axial reciprocating motion of the oscillating heads 505 disperses the feed in the feed bag to prevent localized clumping of the feed.

[0055] The calendering mechanism 6 includes multiple contact plates 613 located above the homogenizing mechanism 5. During the process of pressing the feed bag downwards, the contact plates 613 perform a lateral eccentric rotational motion to rub the surface of the feed bag to expel the gas inside the bag.

[0056] The side-pulling mechanism 7 includes multiple upper clamping plates 715 and lower clamping plates 713 respectively located on both sides inside the shaping chamber 2. The upper clamping plates 715 and lower clamping plates 713 are arranged in pairs. The upper clamping plates 715 and lower clamping plates 713 clamp the side of the feed bag and pull it outward through the opposite movement of the upper clamping plates 715 and lower clamping plates 713, providing lateral space for the feed inside the bag to be compressed and stretched.

[0057] Please see Figures 4-5 The homogenizing mechanism 5 also includes: a matrix plate 501, a positioning plate 502, a positioning seat 503, and a moving groove 504;

[0058] The matrix plate 501 is located inside the shaping chamber 2, and the top of the matrix plate 501 has multiple grooves. Multiple positioning plates 502 are respectively located in the grooves at corresponding positions on the top of the matrix plate 501, and multiple positioning seats 503 are respectively located in the grooves at corresponding positions on the top of the matrix plate 501. The moving groove 504 is located inside the positioning seat 503.

[0059] The homogenizing mechanism 5 also includes: a buffer pad 506, a first spring 507, and a synchronizing rod 508;

[0060] A buffer pad 506 is fitted onto the outside of the positioning seat 503. The bottom of the oscillating head 505 is connected to the corresponding position of the outer wall of the buffer pad 506. A first spring 507 is located outside the positioning seat 503, and the two ends of the first spring 507 are respectively connected to the bottom of the buffer pad 506 and the corresponding position of the outer wall of the positioning seat 503. A synchronizing rod 508 passes through the bottom of the positioning seat 503. A gear 510 is provided at one end of the synchronizing rod 508. Multiple passage slots 509 are equidistantly opened on the outer wall of the synchronizing rod 508.

[0061] The homogenizing mechanism 5 also includes: a rotating wheel 511, a synchronous wheel 512, and a first motor 514;

[0062] The rotating wheel 511 is rotatably connected to one side of the matrix plate 501 side wall, and the synchronous wheel 512 is rotatably connected to the other side of the matrix plate 501 side wall. A chain 513 is connected between the synchronous wheel 512 and the rotating wheel 511. The first motor 514 is mounted on the side wall of the matrix plate 501 through the frame, and the output end of the first motor 514 is connected to one side of the rotating wheel 511.

[0063] Specifically, when the feed bag is conveyed to the shaping chamber 2 by the input belt 1, the first motor 514 drives the rotating wheel 511 to rotate through the output end. The rotating wheel 511 drives the synchronous wheel 512 to rotate synchronously through the chain 513. The chain 513 meshes with the teeth of the gear 510. The chain 513 drives multiple synchronous rods 508 to rotate synchronously through the gear 510.

[0064] Furthermore, in the initial state, the bottom end of the oscillating head 505 is located in the passage groove 509 opened on the outer wall of the synchronizing rod 508. When the synchronizing rod 508 rotates, the rod body of the synchronizing rod 508 lifts the bottom end of the oscillating head 505, and the oscillating head 505 moves upward relative to the positioning seat 503. The oscillating head 505 pulls the buffer pad 506 to move synchronously, the first spring 507 is stretched, and the top of the oscillating head 505 protrudes from the positioning plate 502 to vibrate the feed bag. The synchronous rotation of the synchronizing rod 508 causes multiple oscillating heads 505 to protrude from the positioning plate 502. The synchronous rotation of multiple synchronizing rods 508 causes multiple points of the matrix plate 501 to simultaneously excite the feed bag, thereby evenly dispersing the feed in the bag and preventing the feed from clumping and puncturing the feed bag during the subsequent compaction process.

[0065] It should be noted that the selection of the first motor 514 and the control unit in the above description are selected as needed. This part is well-known technology in the field and will not be described in detail here.

[0066] It should be noted that, as described above, the sprocket 511, the synchronous pulley 512, the gear 510, and the chain 513 constitute a sprocket and chain structure. The structure transmits motion and power through meshing. The chain drive has no elastic slippage and can maintain a stable transmission ratio. This part is well-known technology in the field and will not be described in detail here.

[0067] Please see Figures 6-7 The calendering mechanism 6 also includes: a fixed plate 601, a guide seat 602, a floating shaft 603, and a synchronization plate 604;

[0068] The fixed plate 601 is located on the top of the inner wall of the shaping chamber 2. Two guide seats 602 are symmetrically embedded on the top of the fixed plate 601. Two floating shafts 603 are respectively located inside the guide seats 602 at corresponding positions. The synchronization plate 604 is located above the fixed plate 601. The top of the floating shaft 603 passes through the bottom of the synchronization plate 604 at the corresponding position.

[0069] The rolling mechanism 6 also includes: a push plate 605, an electric push rod 609, a pressure plate 606, and a second spring 608;

[0070] A push plate 605 is located below a fixed plate 601. The bottom end of a floating shaft 603 passes through the corresponding position on the top of the push plate 605. An electric push rod 609 is installed on the top of the fixed plate 601. The telescopic part of the electric push rod 609 is connected to the corresponding position on the top of the push plate 605. A pressure plate 606 is located below the push plate 605. The top of the pressure plate 606 is provided with two telescopic rods 607. The top end of the telescopic rods 607 passes through the bottom end of the floating shaft 603. A second spring 608 is located outside the telescopic rods 607, and the two ends of the second spring 608 are connected to the corresponding positions on the bottom of the push plate 605 and the corresponding positions on the top of the pressure plate 606, respectively.

[0071] The calendering mechanism 6 also includes: a mounting shell 610, a rotating seat 611, a second motor 614, a connecting block 612, and a third spring 616;

[0072] The top of the mounting housing 610 is connected to the bottom of the pressure plate 606. The top of the rotating seat 611 is rotatably connected to the bottom of the mounting housing 610. The second motor 614 is located inside the mounting housing 610. The output end of the second motor 614 is connected to the top of the rotating seat 611. One end of the connecting block 612 is rotatably connected to the bottom of the rotating seat 611. The bottom of the other end of the connecting block 612 is rotatably connected to the top of the contact plate 613 through a column. Multiple third springs 616 are located below the mounting housing 610. Both ends of the third spring 616 are connected to universal seats 615. The two universal seats 615 at both ends of the third spring 616 are respectively connected to the corresponding positions of the bottom of the mounting housing 610 and the top of the contact plate 613.

[0073] Specifically: after the feed in the feed bag is dispersed by the homogenizing mechanism 5, the telescopic part of the electric push rod 609 extends and pushes the push plate 605 downward. The push plate 605 drives the two floating shafts 603 to move downward relative to the guide seat 602. The two floating shafts 603 drive the synchronous plate 604 to move downward synchronously. When the push plate 605 moves downward, it drives the pressure plate 606 to move downward synchronously through the second spring 608. When the pressure plate 606 contacts the top of the feed bag, the top of the telescopic rod 607 extends into the bottom of the floating shaft 603, and the second spring 608 is compressed. The second spring 608 pushes the pressure plate 606 in the opposite direction through its own elastic force, so that the pressure plate 606 fits tightly with the outer contour of the feed bag. The telescopic part of the electric push rod 609 continues to extend, so that the pressure plate 606 compacts the feed in the feed bag.

[0074] Furthermore, when the pressure plate 606 is in contact with the outer contour of the feed bag, the contact plate 613 deflects according to the real-time shape of the outer contour of the feed bag. The contact plate 613 drives the connecting block 612 to rotate relative to the rotating seat 611 through the column at the bottom of the connecting block 612. The third spring 616 in the deflection direction of the contact plate 613 is compressed, and the third spring 616 in the opposite direction of the deflection direction of the contact plate 613 is stretched. The second motor 614 drives the rotating seat 611 to rotate through the output end. The rotating seat 611 drives the contact plate 613 to make an eccentric horizontal circular motion through the connecting block 612 to rub the feed bag and expel the residual gas in the feed bag, preventing the bag from bursting due to residual gas in the bag during the process of compacting the feed.

[0075] It should be noted that the selection of the second motor 614 and the control unit in the above description are selected as needed. This part is well-known technology in the field and will not be described in detail here.

[0076] It should be noted that the electric actuator 609 described above is a new type of linear actuator composed of an electric motor, a actuator, and a control device. It is an electric drive device that converts the rotary motion of the electric motor into the linear reciprocating motion of the actuator. This part is well-known technology in the field and will not be described in detail here.

The external control system controls the rotating rod 703 to rotate with its middle part as the axis. The rotating rod 703 pulls the two mounting brackets 701 to move synchronously in the center through the linkage rod 702. When the abutment plate 710 is above the feed bag, the rotating rod 703 stops rotating. The third motor 720 drives the drive wheel 718 to rotate through the output end. The drive wheel 718 drives the driven wheel 717 to rotate through the transmission chain 719. The driven wheel 717 drives the central shaft 712 to rotate synchronously. The outer wall of the top end of the central shaft 712 is provided with a threaded groove. The threaded groove of the outer wall of the top end of the central shaft 712 meshes with the internal thread of the inner wall of the abutment plate 710, so that the abutment plate 710 moves downward along the axis of the central shaft 712. The fourth spring 711 is compressed, and the protruding part at the bottom of the front end of the abutment plate 710 abuts against the top of the feed bag.

[0084] Furthermore, the downward movement of the abutment plate 710 causes the linkage plate 709 to move downward simultaneously. The bottom column of the linkage plate 709 has an inclined surface, and the end of the pressing block 708 away from the central shaft 712 also has an inclined surface, with the two inclined surfaces abutting against each other. When the linkage plate 709 moves downward, it pushes the pressing block 708 closer to the central shaft 712 through the abutment of the inclined surfaces. The end of the pressing block 708 without an inclined surface abuts against the inclined surface of the outer wall of the bushing 706. The pressing block 708 pushes the bushing 706 down relative to the mounting base 704 through this inclined surface. The limiting block 707 restricts the bushing 706 to prevent it from rotating. The bottom end of the bushing 706 presses down on the upper clamping plate 715, causing the upper clamping plate 715 to move downward. 15. The lower clamping plate 713 approaches, and the upper clamping plate 715 has columns on both sides, which are inserted into the stroke groove 714. The columns on both sides of the upper clamping plate 715 slide from the top to the bottom of the stroke groove 714, and the fifth spring 716 is compressed. The upper clamping plate 715 and the lower clamping plate 713 clamp the side of the feed bag together. The external control system controls the rotating rod 703 to rotate in the opposite direction with its middle part as the axis. The two mounting brackets 701 move away from each other synchronously. While the upper clamping plate 715 and the lower clamping plate 713 clamp the side of the feed bag, they pull the side of the feed bag to both sides to provide lateral space for feed calendering and prevent feed from accumulating on the side and causing the side seam to break.

[0085] It should be noted that the selection of the third motor 720 and the control unit in the above description are selected as needed. This part is well-known technology in the field and will not be elaborated here.

[0086] It should be noted that, as described above, the drive wheel 718, driven wheel 717, and transmission chain 719 constitute a sprocket and chain structure. The structure transmits motion and power through meshing. The chain drive has no elastic slippage and can maintain a stable transmission ratio. This part is well-known technology in the field and will not be described in detail here.

[0087] Working principle: During use, the operator places the filled feed bag on the input belt 1, which transports the feed bag to the shaping chamber 2. The operator starts the first motor 514 through the external control system, which makes the multiple homogenizing mechanisms 5 embedded in the matrix plate 501 operate synchronously to disperse and homogenize the feed in the feed bag. After homogenization, the operator starts the electric push rod 609 and the second motor 614 through the external control system. The calendering mechanism 6 presses the feed bag downward and rubs the feed bag to expel the gas inside. While calendering the feed, the operator starts the third motor 720 through the external control system and controls the rotating rod 703 to rotate. The side pulling mechanism 7 clamps the side of the feed bag. The operator controls the rotating rod 703 to rotate in the opposite direction through the external control system, which makes the side pulling mechanism 7 pull the two sides of the feed bag outward synchronously. After the feed bag is shaped, it leaves the shaping chamber 2 and enters the output belt 3. As the output belt 3 outputs the shaped feed bag forward, the robotic arm 4 grabs the shaped feed bag and stacks it.
