Description

Technical Field

[0001] This invention relates to the field of packaging bag breaking technology, and more specifically, to a bag breaking mechanism. Background Technology

[0002] Existing bag-breaking mechanisms typically use robotic arms to lift packaging bags upwards and then lower them downwards for breaking. This results in significant vertical displacement, increasing the overall height of the equipment and raising energy consumption. Furthermore, these mechanisms lack effective load-bearing support for the packaging bags during the breaking process, making them prone to shifting or collapsing, thus affecting the breaking effect and cutting efficiency. In addition, after breaking, the packaging bags require additional pushing devices or manual assistance to unload, meaning the unloading and breaking actions cannot be completed continuously on the same conveyor line, leading to complex equipment structures and large footprints. Summary of the Invention

[0003] To address the above shortcomings, this invention provides a bag-breaking mechanism that solves the technical problems of high energy consumption during bag breaking and cumbersome manual bag unloading.

[0004] To achieve the above objectives, the technical solution adopted by the present invention is as follows: The bag-breaking mechanism includes a feeding conveyor belt, a discharging conveyor belt, a bag-breaking knife, and a main frame. The feeding conveyor belt is higher than the discharging conveyor belt. It also includes: Two guide side panels, with a breaking space and a release space between them, through which the packaging bag passes; A sprocket and chain are mounted on the guide side plate, with one end of the sprocket extending into the bag-breaking space; The triangular plate, blade, and load-bearing ball are designed to support the bag. The blade is located on the side wall of the triangular plate, and the load-bearing ball is located on the top of the triangular plate. When the bag passes through the bag breaking space, the bag leaves the feeding conveyor belt, the blade pierces into the bag, and the load-bearing ball supports the bag. The system consists of a connecting block, an electromagnet, a rack and pinion, and a limiting assembly. The chain drives the connecting block to move horizontally. The triangular plate is rotatably connected to the connecting block. After the bag is broken, it enters the release space. The triangular plate engages with the rack and pinion. At the same time, the electromagnet is energized to drive the limiting assembly to release the triangular plate. The triangular plate rotates 180 degrees, from an upward position to a downward position and remains there, releasing the packaging bag. After release, the above process is repeated, with the triangular plate rotating 180 degrees and facing upward, completing the work cycle.

[0005] Furthermore, the limiting component includes a circular hole 1 on the side wall of the connecting block, a rotating block inside the circular hole 1, the rotating block being axially limited, a triangular plate mounted on the side wall of the rotating block, a gear meshing with a rack mounted on the lower end of the triangular plate, an L-shaped hole on the upper end of the rotating block, the lower end of the L-shaped hole communicating with the circular hole 1, an L-shaped rod installed inside the L-shaped hole, a gap between the L-shaped hole and the L-shaped rod, a compression spring 1 inside the gap, one end of the compression spring 1 being fixedly connected to the L-shaped rod, and the other end being fixedly connected to the L-shaped hole; the lower end of the L-shaped rod is rectangular, and the side wall of the rotating block has a limiting hole that fits with the lower end of the L-shaped rod with a clearance; when the upper end of the L-shaped rod passes the electromagnet, the electromagnet is energized and a repulsive force is generated between it and the L-shaped rod, the L-shaped rod exerts force on the compression spring 1, the compression spring 1 contracts, the lower end of the L-shaped rod leaves the limiting hole, and the gear can rotate; when the L-shaped rod leaves the electromagnet, the lower end of the L-shaped rod inserts into the limiting hole, and the gear cannot rotate; the lower end of the L-shaped rod is chamfered to facilitate insertion into the limiting hole.

[0006] Furthermore, the lower end of the L-shaped rod is provided with a stabilizing hole, and the side wall of the gap is provided with a stabilizing rod, which is inserted into the stabilizing hole; the side wall of the rotating block is provided with a compression spring II, one end of which is fitted with a limit ball, and the side wall of the round hole is provided with a hemispherical recess corresponding to the limit ball.

[0007] Furthermore, the guide side plate has a rectangular opening on its side wall, and sprockets are installed at both ends of the rectangular opening. Both ends of the chain are connected to the sprockets. The sprockets have an independent drive system, and the chain drives the connecting block to slide along the rectangular opening. The rectangular opening supports the weight of the connecting block.

[0008] Furthermore, the electromagnet and the rack form a switch assembly, which is located at one end and the other end of the release space. The rack is located on the side of the guide plate near the packaging bag, and the electromagnet is located on the other side of the guide plate. The rack and the electromagnet are positioned correspondingly, and the rack only drives the gear to rotate 180 degrees.

[0009] Furthermore, a hydraulic rod is provided on the side wall of the main frame, and the telescopic end of the hydraulic rod is fixedly connected to the guide side plate.

[0010] Furthermore, a second hydraulic rod is provided above the release space, a pusher plate is provided at the lower end of the second hydraulic rod, and a receiving hopper is provided below the packing space.

[0011] Furthermore, one end of the guide side plate is provided with an inclined plate, and the inclined plates at different positions are flared.

[0012] Furthermore, the blade is tilted, with an angle ranging from 30 to 45 degrees.

[0013] Compared with the prior art, the beneficial effects of this invention are: the packaging bag enters the breaking space with the assistance of the feeding conveyor belt, the blades on the side wall of the triangular plate pierce the packaging bag, and the load-bearing ball at the top of the triangular plate provides load-bearing support for the packaging bag, so that the packaging bag maintains a stable tension state during the breaking process, avoiding insufficient breaking due to packaging bag displacement or collapse, thus improving the breaking efficiency and quality. The chain drives the connecting block to move horizontally, moving the triangular plate from the breaking space to the release space. In the release space, the meshing of the rack and pinion drives the triangular plate to rotate 180 degrees, changing the load-bearing ball from an upward to a downward position, thus realizing the automatic release of the packaging bag. The entire breaking, transfer, flipping, release, and reset actions are completed continuously on the same mechanism, eliminating the need for an additional bag unloading device, effectively simplifying the equipment structure and reducing the floor space required.

[0015] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0016] Please see Figure 1-4 The present invention provides a packing breaking mechanism, including a feeding conveyor belt 1, a discharging conveyor belt 2, a packing breaking knife 3, and a main frame 4, wherein the feeding conveyor belt 1 is higher than the discharging conveyor belt 2, and further includes: Two guide side plates 5, with a bag breaking space 6 and a release space 7 between the guide side plates 5, and the packaging bag passes through the bag breaking space 6; A sprocket 8 and a chain 9 are installed on the guide side plate 5, with one end of the sprocket 8 extending into the bag breaking space 6; The triangular plate 10, the blade 11, and the load-bearing ball 12 are provided. The blade 11 is located on the side wall of the triangular plate 10, and the load-bearing ball 12 is located on the top of the triangular plate 10. When the packaging bag passes through the bag breaking space 6, the packaging bag leaves the feeding conveyor belt 1, the blade 11 pierces into the packaging bag, and the load-bearing ball 12 plays a load-bearing role on the packaging bag. The system consists of a connecting block 13, an electromagnet 14, a rack 15, and a limiting assembly. The chain 9 drives the connecting block 13 to move horizontally. The triangular plate 10 is rotatably connected to the connecting block 13. After the bag is broken, it enters the release space 7. The triangular plate 10 engages with the rack 15. At the same time, the electromagnet 14 is energized to drive the limiting assembly to release the triangular plate 10. The triangular plate 10 rotates 180 degrees, from an upward position to a downward position and remains there, releasing the packaging bag. After the release is completed, the above process is repeated, with the triangular plate 10 rotating 180 degrees and facing upward, completing the work cycle.

[0017] In practical applications, the packaging bag is conveyed by the feeding conveyor belt 1 to the bag-breaking space 6 formed between the two guide side plates 5. The packaging bag is detached from the support of the feeding conveyor belt 1. At this time, the sprocket 8 and chain 9 installed on the guide side plate 5 continue to operate. The chain 9 drives the connecting block 13 to move along the guide side plate 5. The triangular plate 10 rotatably connected to the connecting block 13 moves accordingly. The blade 11 on the side wall of the triangular plate 10 pierces into the side wall of the packaging bag. At the same time, the load-bearing ball 12 at the top of the triangular plate 10 contacts the packaging bag, providing temporary support and load-bearing function for the packaging bag, keeping the packaging bag in a taut state, so that the bag-breaking knife 3 can cut fully and complete the bag-breaking action. As chain 9 continues to drive connecting block 13 to move horizontally, the broken packaging bag, along with triangular plate 10, moves from the breaking space 6 into the release space 7. During the path into the release space 7, triangular plate 10 meshes with the fixed rack 15. At this time, electromagnet 14 is simultaneously energized, driving the limiting component to release the constraint on the rotational freedom of triangular plate 10. Due to the meshing action of rack 15 on triangular plate 10, triangular plate 10 is forced to rotate relative to connecting block 13, turning 180 degrees, changing from the original state of the bearing ball 12 facing upwards to a state of the bearing ball 12 facing downwards and the blade 11 also turning downwards. Electromagnet 14 is de-energized, keeping the bearing ball 12 in the downward position. This allows the packaging bag to slide off triangular plate 10 under its own weight, falling into the discharge conveyor belt 2 below, and being transported away from the breaking mechanism by the discharge conveyor belt 2, thus completing the release of the packaging bag. After the release is complete, the electromagnet 14 is energized, which re-constrains the rotation of the triangular plate 10. The triangular plate 10 meshes with the rack 15 again and rotates 180 degrees in the opposite direction, restoring the initial orientation of the load-bearing ball 12 facing upward. At the same time, the limiting component locks the position to ensure that the triangular plate 10 is in a state ready to receive the next packaging bag. At this point, the cycle of breaking and releasing a single packaging bag is complete.

[0018] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 The limiting component includes a circular hole 21 on the side wall of the connecting block 13, a rotating block 22 inside the circular hole 21, the rotating block 22 being axially limited, a triangular plate 10 mounted on the side wall of the rotating block 22, a gear 23 meshing with a rack 15 mounted on the lower end of the triangular plate 10, an L-shaped hole 24 at the upper end of the rotating block 22, the lower end of the L-shaped hole 24 communicating with the circular hole 21, an L-shaped rod 25 installed inside the L-shaped hole 24, a gap 26 between the L-shaped hole 24 and the L-shaped rod 25, a compression spring 27 inside the gap 26, one end of the compression spring 27 being fixedly connected to the L-shaped rod 25, and the other end being fixedly connected to the L-shaped rod 25. Hole 24 provides a fixed connection; the lower end of the L-shaped rod 25 is rectangular, and the side wall of the rotating block 22 is provided with a limiting hole 28 that fits with the lower end of the L-shaped rod 25 with a clearance; when the upper end of the L-shaped rod 25 passes the electromagnet 14, the electromagnet 14 is energized and a repulsive force is generated between it and the L-shaped rod 25, the L-shaped rod 25 applies force to the compression spring 27, the compression spring 27 contracts, the lower end of the L-shaped rod 25 leaves the limiting hole 28, and the gear 23 can rotate; when the L-shaped rod 25 leaves the electromagnet 14, the lower end of the L-shaped rod 25 is inserted into the limiting hole 28, and the gear 23 cannot rotate; the lower end of the L-shaped rod 25 is chamfered to facilitate insertion into the limiting hole 28.

[0019] In practical applications, when the connecting block 13 drives the triangular plate 10 into the release space 7, the gear 23 and the fixed rack 15 engage. At this time, the electromagnet 14 is energized, and the magnetic field it generates acts on the upper end of the L-shaped rod 25. Due to the repulsive force between the electromagnet 14 and the L-shaped rod 25, the upper end of the L-shaped rod 25 is pushed outward, and the L-shaped rod 25 slides in the L-shaped hole 24, and the spring is compressed and stores energy. As the L-shaped rod 25 moves, its lower rectangular part completely disengages from the limiting hole 28 on the side wall of the rotating block 22. After disengaging, the rotational freedom of the rotating block 22 is released. After the rotating block 22 is unlocked, due to the meshing relationship between the gear 23 and the rack 15, the gear 23 is forced to rotate under the drive of the continued translation of the connecting block 13, which drives the rotating block 22 to rotate in the circular hole 21. This causes the triangular plate 10 to rotate 180 degrees around the axis of the rotating block 22, changing from the upward orientation of the load-bearing ball 12 to the downward orientation of the load-bearing ball 12. During the rotation process, the electromagnet 14 is continuously energized to keep the lower end of the L-shaped rod 25 out of the limiting hole 28, ensuring that the rotation of the rotating block 22 is not interfered with. As the connecting block 13 continues to move forward, after the upper end of the L-shaped rod 25 leaves the effective range of the electromagnet 14, the electromagnet 14 is de-energized, the repulsive force disappears, and the compressed spring 27 releases energy, pushing the L-shaped rod 25 to slide back and reset along the L-shaped hole 24. Its lower end is reinserted into the limiting hole 28. Since the lower end of the L-shaped rod 25 has a chamfer, it can be smoothly guided during the insertion process and smoothly enter the limiting hole 28 to achieve clearance fit, thereby locking the rotating block 22 again, keeping the triangular plate 10 stably in the downward position, and completing the packaging bag release action. After the release is complete, the connecting block 13 continues to move horizontally with the chain 9, and the gear 23 approaches the rack 15 again. At this time, the electromagnet 14 is energized again, repeating the above unlocking process, so that the rotating block 22 can rotate in the opposite direction. The gear 23 meshes with the rack 15 in the opposite direction, driving the rotating block 22 to rotate 180 degrees. The triangular plate 10 returns to the initial pack breaking posture with the load-bearing ball 12 facing upward. Then the electromagnet 14 is de-energized, the spring resets, and the limit assembly completes a complete working cycle. Throughout the process, the timing of the electromagnet 14 being switched on and off is precisely matched with the position of the connecting block 13 and the meshing range of the rack 15, ensuring the accuracy and stability of the flipping action of the triangular plate 10.

[0020] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 The lower end of the L-shaped rod 25 is provided with a stabilizing hole 31, and the side wall of the gap 26 is provided with a stabilizing rod 32, which is inserted into the stabilizing hole 31; the side wall of the rotating block 22 is provided with a compression spring 33, one end of the compression spring 33 is installed with a limit ball 34, and the side wall of the round hole 21 is provided with a hemispherical recess 35 corresponding to the limit ball 34.

[0021] In practical applications, the L-shaped rod 25 can slide more stably thanks to the stabilizing hole 31 and the stabilizing rod 32. The compression spring 33 and the limiting ball 34 generate shear force when the rotating block 22 rotates between the circular holes 21, pressing the limiting ball 34 into the rotating block 22. When the limiting ball 34 aligns with the hemispherical recess 35, it can restrict the rotation of the rotating block 22 to a certain extent, giving the rotating block 22 a clear tactile feedback during rotation and achieving precise positioning. Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 The guide side plate 5 has a rectangular opening 41 on its side wall. The sprocket 8 is installed at both ends of the rectangular opening 41. The two ends of the chain 9 are connected to the sprocket 8. The sprocket 8 is equipped with an independent drive system. The chain 9 drives the connecting block 13 to slide along the rectangular opening 41. The rectangular opening 41 bears the weight of the connecting block 13.

[0022] In practical applications, a rectangular opening 41 is opened on the side wall of the guide side plate 5. The rectangular opening 41 extends along the movement direction of the connecting block 13 and forms a sliding guide channel for the connecting block 13. The sprockets 8 are arranged in pairs at both ends of the rectangular opening 41 and are respectively installed on the side wall through bearing seats. The chain 9 is closed and wrapped around the sprockets 8 at both ends. The sprockets 8 are provided with rotational power by an independent drive system, which drives the chain 9 to run continuously between the two ends of the rectangular opening 41.

[0023] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 Electromagnet 14 and rack 15 form a switch assembly. The switch assembly is located at one end and the other end of the release space 7. Rack 15 is located on the guide side plate 5 near the packaging bag, and electromagnet 14 is located on the other side of the guide side plate 5. The positions of rack 15 and electromagnet 14 correspond. Rack 15 drives gear 23 to rotate 180 degrees.

[0024] In practical applications, the rack 15 is fixedly installed on the inner wall of the guide side plate 5, that is, the side close to the packaging bag, while the electromagnet 14 is installed on the outer wall of the guide side plate 5, corresponding to the position of the rack 15. The two sets of switch assemblies are respectively arranged at the entrance and exit of the release space 7. The length of the rack 15 teeth and the installation position are designed so that when the connecting block 13 carries the triangular plate 10 and moves through the rack 15, the gear 23 only meshes with the rack 15 for one stroke, which corresponds to the gear 23 rotating exactly 180 degrees. The energization time of the electromagnet 14 is synchronized with the time when the connecting block 13 reaches the starting end of the rack 15. Its magnetic force acts on the L-shaped rod 25 to unlock the rotating block 22, so that the gear 23 can rotate freely.

[0025] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 The main frame 4 has a hydraulic rod 61 on its side wall, and the telescopic end of the hydraulic rod 61 is fixedly connected to the guide side plate 5.

[0026] In practical applications, the extension and retraction of the hydraulic rod 61 can control the width of the tearing space 6, thereby adapting to packaging bags of different widths.

[0027] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 A hydraulic rod 71 is provided above the release space 7, and a pusher plate 72 is provided at the lower end of the hydraulic rod 71. A receiving hopper 73 is provided below the breaking space 6.

[0028] In practical applications, the hydraulic rod 71 extends, causing the pusher plate 72 to move downward and press the packaging bag onto the discharge conveyor belt 2; the material after the packaging bag is broken is transported to the outside through the receiving hopper 73.

[0029] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 One end of the guide side plate 5 is provided with an inclined plate 81, and the inclined plates 81 at different positions are flared.

[0030] In practical applications, the inclined plate 81 facilitates the movement of the packaging bag into the broken bag space 6.

[0031] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 The blade 11 is tilted, with an angle ranging from 30 to 45 degrees.

[0032] In practical applications, the specific angle of the blade 11 is set according to actual needs, so that the blade 11 can penetrate the packaging bag laterally while the load-bearing ball 12 provides stable support for the packaging bag.
