A smart hanging conveyor device for packaging bags used in the production of pet cat litter.

Abstract

This invention discloses an intelligent suspended conveying device for packaging bags used in pet cat litter production, relating to the technical field of intelligent suspended conveying systems. It includes an elevated frame arranged in a closed-loop track, with the bag continuously circulating along the closed-loop track. As the cat litter-filled bags accumulate, a perforated plate moves downwards, causing the corners of the suspension frame to contact four abutment blocks. The suspension frame is then held and limited, ensuring it is parallel to the ground. This restricts unnecessary independent rotation of the load-bearing frame, keeping the cat litter bags in a neat and horizontal position throughout the process. This prevents bag tilting, seal cracking, and cat litter spillage caused by accidental deflection of the load-bearing frame, improving the cleanliness of the production site and material utilization. If a cat litter bag leaks due to quality issues, the leaked cat litter falls through the perforated plate into a collection bag below. The collection bag expands and contracts synchronously with the connecting rod, conforming to the receiving area throughout the process, significantly improving spillage collection efficiency.

Description

Technical Field

[0001] This invention relates to the field of intelligent suspended conveying systems, specifically to an intelligent suspended conveying device for packaging bags used in the production of pet cat litter. Background Technology

[0002] In the large-scale production and processing of pet cat litter, after the finished cat litter is filled and sealed, it generally needs to rely on an intelligent suspended conveyor system to complete the long-distance transfer of packaging bags, workstation transfer and fixed-point unloading operations.

[0003] At present, existing intelligent hanging conveyor devices for cat litter bags still have many technical defects: conventional hanging load-bearing frames are mostly fixed structures, which cannot adaptively adjust the level according to the difference in the weight of the cat litter bags. When the material load is uneven, the frame is prone to tilting, swinging and deflection. The conveying stability is poor and it is difficult to match the smooth and regular continuous conveying requirements of intelligent hanging conveyor systems.

[0004] The existing technical solutions have obvious limitations in practice: cat litter bags with different load capacities will cause uneven stress on the rack, making the rack tilted and skewed throughout the process. The overall posture is unstable during the suspended conveying process, which cannot meet the requirements of the orderly conveying operation of the intelligent suspended conveying system. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides an intelligent suspended conveying device for packaging bags used in pet cat litter production. This device solves the problem mentioned in the background art, where cat litter packaging bags with different load capacities cause uneven stress on the carrier, resulting in the carrier being tilted or skewed throughout the process. This leads to overall instability in the suspended conveying process and makes it unsuitable for the orderly conveying requirements of an intelligent suspended conveying system.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an intelligent suspended conveying device for packaging bags used in the production of cat litter, comprising an elevated frame arranged in a closed-loop track, a chain conveyor belt that circulates along the closed-loop track of the elevated frame to form a continuous circular traction loop, and an installation chain suspended below the chain conveyor belt and moving synchronously with the chain conveyor belt. The intelligent suspended conveying device for packaging bags used in the production of cat litter further includes: a transport mechanism installed on the installation chain for suspending and transporting materials; the transport mechanism includes components rotatably mounted on the installation chain. A suspension frame for dumping materials, a load-bearing frame mounted on the suspension frame, a perforated plate slidably mounted on the inner wall of the load-bearing frame for placing materials, a trigger rod mounted on the bottom of the perforated plate, a slide rod slidably mounted inside the load-bearing frame, a connecting rod for connecting the slide rod and the trigger rod, an electric push rod mounted on the mounting chain, an abutment block mounted on the electric push rod for leveling the suspension frame, and a connecting rope for connecting the abutment block and the slide rod; a first spring is provided between the perforated plate and the load-bearing frame, and the perforated plate is reset by the first spring.

[0007] According to the above technical solution, the electric push rod is configured as a non-self-locking type, and the transport mechanism also includes a collection bag installed under the load frame and connected to the connecting rod at the same time. The collection bag is connected to the perforated plate.

[0008] In the above embodiment, as the bags filled with cat litter accumulate, the perforated plate moves downward. The movement of the perforated plate causes the trigger rod to move simultaneously. The movement of the trigger rod causes the connecting rod to move and simultaneously pulls the slide rod downward. The downward movement of the slide rod tightens the connecting rope. The tension generated by the tightening of the connecting rope drags the movable end of the electric push rod downward. The electric push rod is stationary when the power is off. It has no internal self-locking structure, so external force can directly stretch the movable end. When the power is on, the movable end automatically retracts. In normal electric control operation, the extension of the movable end of the electric push rod causes the abutment block to move. Through the contact between the corner of the suspension frame and the four abutment blocks, the suspension frame is held and limited, making the suspension frame parallel to the ground.

[0009] According to the above technical solution, the intelligent hanging conveyor device for packaging bags used in the production of cat litter also includes a tilting mechanism and a protective mechanism; the tilting mechanism is installed on the load-bearing frame and is used to assist in tilting the material; the protective mechanism is installed on the load-bearing frame and is used to prevent the load-bearing frame from falling after the material is loaded.

[0010] According to the above technical solution, the tilting mechanism includes a tilting plate rotatably mounted on the load frame, a lever one rotatably mounted on the tilting plate, a lever two rotatably mounted on the tilting plate, and a snap-fit ​​groove formed on the tilting plate.

[0011] According to the above technical solution, a magnetic suction component is provided inside the tilting plate, and a first torsion spring is provided between the first lever and the tilting plate. The first torsion spring drives the first lever to reset. A second torsion spring is provided between the second lever and the tilting plate. The second torsion spring drives the second lever to reset.

[0012] In the above embodiments, when the packaging bag is being discharged by the tilting plate, the falling speed of the packaging bag is slowed down by the elastic resistance of the first and second torsion springs.

[0013] According to the above technical solution, the tilting mechanism further includes a pull rod slidably installed in the suspension frame, a locking block installed on the pull rod, a limiting button installed on the tilting plate, and a limiting frame installed on the electric push rod; a second spring is provided between the pull rod and the suspension frame, and the pull rod is driven to return to its original position by the second spring; the contact surface between the locking block and the tilting plate is set as an inclined surface; the locking block matches the locking groove.

[0014] In the above embodiment, the tilting plate is rotatably mounted on the tilting side of the load frame. Initially, it is retracted and closed, sealing the side opening of the load frame. In the power-off state, the movable end of the electric push rod drives the limiting frame to move synchronously, so that the limiting frame covers the periphery of the limiting button, making the limiting button unable to move, that is, the tilting plate cannot move significantly.

[0015] According to the above technical solution, the tilting mechanism further includes a connecting frame installed below the load-bearing frame, an elastic telescopic rod installed on the connecting frame, a support plate installed on the elastic telescopic rod, and a magnet block installed on the support plate; the support plate is provided with an elastic edging; the magnetic attraction component in the tilting plate can be magnetically attached and fixed to the magnet block, and the attraction force is set to be able to be directly overcome by human hand, so as to realize the rapid separation and disconnection of the tilting plate and the magnet block.

[0016] In the above embodiments, after the tilting plate is released, it will fall onto the support plate with elastic edging due to gravity. The closing impact is buffered by the elastic telescopic rod, reducing collision noise. At the same time, the magnetic attraction component in the tilting plate is attached to the magnet block, which strengthens the fixation of the tilting plate.

[0017] According to the above technical solution, the protective mechanism includes a slide groove installed on the load-bearing frame, a baffle plate slidably installed on the slide groove, and an L-shaped rod installed on the hollow plate; the L-shaped rod is provided with toothed grooves.

[0018] According to the above technical solution, the protective mechanism further includes a gear frame mounted on the load-bearing frame and a guide rod mounted on the gear frame; the gear frame meshes with the tooth groove opened on the L-shaped rod.

[0019] According to the above technical solution, the protective mechanism further includes a rack rod slidably mounted on the guide rod and a connecting button for connecting the rack rod and the baffle; the rack rod meshes with the gear carrier.

[0020] In the above embodiment, when the perforated plate moves downward due to pressure, it will drive the L-shaped rod to move synchronously. The movement of the L-shaped rod, through its own toothed groove, causes the gear of the gear frame to rotate clockwise. The clockwise rotation of the gear drives the rack rod to move upward along the guide rod. The movement of the guide rod drives the connecting button to move. The movement of the connecting button drives the baffle to move along the slide groove, so that the baffles on both sides move synchronously. The higher the material loaded on the perforated plate, the higher the baffles on both sides will automatically rise.

[0021] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. In this invention, as the cat litter-filled bags accumulate, the perforated plate moves downward, causing the corners of the hanging frame to contact the four abutment blocks. The hanging frame is held in place and parallel to the ground, limiting unnecessary rotation of the load-bearing frame. This ensures the cat litter bags remain in a neat and horizontal position throughout the process, preventing bag tilting, seal cracking, and cat litter spillage caused by accidental deflection of the load-bearing frame. This improves the cleanliness of the production site and material utilization. If the cat litter bags leak due to quality issues, the leaked cat litter will fall through the perforated plate into the collection bag below. The collection bag expands and contracts synchronously with the connecting rod, fitting the receiving area throughout the process, significantly improving the spillage collection effect.

[0022] 2. In this invention, the tilting plate is rotatably mounted on the tilting side of the load-bearing frame. Initially, it retracts and closes, sealing the side opening of the load-bearing frame. In the power-off state, the movable end of the electric push rod drives the limiting frame to move synchronously, so that the limiting frame covers the periphery of the limiting button, preventing the limiting button from moving. That is, the tilting plate cannot move significantly, so it cannot rotate on its own without manual unlocking. This avoids accidental opening and closing of the tilting plate due to equipment vibration, conveying bumps, and material shaking, and eliminates accidental opening and leakage. It is suitable for the long-term stable operation of intelligent suspension continuous conveying. After the electric push rod is powered on, the movable end retracts, so that the limiting frame moves out of the range of the limiting button, allowing the suspension frame to rotate to adapt to subsequent unloading operations.

[0023] 3. In this invention, after release, the tilting plate falls onto the elastically edged support plate due to gravity. The closing impact is buffered by the elastic telescopic rod, reducing collision noise. At the same time, the magnetic attraction component in the tilting plate adheres to the magnet block, strengthening the fixed state of the tilting plate. The magnetic attraction is a manually separable design. The unloading station can manually open the magnetic attraction structure as needed, freely controlling the opening and closing sequence of the tilting plate. It is suitable for production processes of fixed-point unloading and centralized discharge, with higher process adaptability. When the tilting plate guides the packaging bag output, the elastic resistance of the first and second torsion springs slows down the falling speed of the packaging bag, avoiding the rapid falling impact that arouses a large amount of cat litter fine powder, effectively suppressing dust in the unloading process, optimizing the workshop environment, and reducing material loss.

[0024] 4. In this invention, when the perforated plate moves downward due to pressure, it will drive the L-shaped rod to move synchronously. The L-shaped rod moves through its own toothed groove, causing the gear of the gear frame to rotate clockwise. The clockwise rotation of the gear drives the rack rod to move upward along the guide rod. The movement of the guide rod drives the connecting button to move. The movement of the connecting button drives the baffle to move along the slide groove, so that the baffles on both sides move synchronously. The higher the material loaded on the perforated plate, the higher the baffles on both sides will automatically rise, forming a barrier on the left and right sides of the packaging bag to prevent the bag from shifting left and right or slipping and falling off when the conveyor is bumpy or the chain shakes.

[0027] 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.

[0028] Example 1: Please see Figures 1-9 One embodiment of the present invention is: an intelligent suspended conveying device for packaging bags used in the production of pet cat litter, comprising an elevated frame 1 arranged in a closed-loop track, a chain conveyor belt 2 that circulates along the closed-loop track of the elevated frame 1 to form a continuous circular traction loop, and an installation chain 3 suspended below the chain conveyor belt 2 and moving synchronously with the chain conveyor belt 2. The intelligent suspended conveying device for packaging bags used in the production of pet cat litter further includes: a transport mechanism installed on the installation chain 3 for suspending and transporting materials; the transport mechanism includes a suspension mechanism rotatably installed on the installation chain 3 for dumping materials. The system includes: a frame 4; a load-bearing frame 5 mounted on the suspension frame 4; a perforated plate 6 slidably mounted on the inner wall of the load-bearing frame 5 for placing materials; a trigger rod 7 mounted on the bottom of the perforated plate 6; a slide rod 9 slidably mounted inside the load-bearing frame 5; a connecting rod 8 for connecting the slide rod 9 and the trigger rod 7; an electric push rod 10 mounted on the mounting chain 3; an abutment block 11 mounted on the electric push rod 10 for leveling the suspension frame 4; and a connecting rope 12 for connecting the abutment block 11 and the slide rod 9. A first spring is provided between the perforated plate 6 and the load-bearing frame 5, and the perforated plate 6 is reset by the first spring.

[0029] The electric push rod 10 is configured to be non-locking. The transport mechanism also includes a collection bag 13 installed under the load frame 5 and connected to the connecting rod 8. The collection bag 13 is connected to the perforated plate 6.

[0030] In the above embodiments, the unnecessary autonomous rotation of the load-bearing frame 5 is restricted, so that the cat litter packaging bag remains in a neat and horizontal position throughout the process, preventing the bag from tilting, the seal from cracking, and the cat litter from spilling due to the accidental deflection of the load-bearing frame 5, thereby improving the cleanliness of the production site and the utilization rate of materials.

[0031] The intelligent hanging conveyor for packaging bags used in pet cat litter production also includes a tilting mechanism and a protective mechanism; the tilting mechanism is installed on the load frame 5 and is used to assist in tilting the material; the protective mechanism is installed on the load frame 5 and is used to prevent the load frame 5 from falling after it is loaded with material.

[0032] In this embodiment, the ring chain conveyor belt 2 is used as the core suspended conveyor, which can perfectly match the automated intelligent suspended conveyor line for cat litter packaging bags in the factory, realizing continuous and cyclical assembly line conveying operations. The overall suspended layout of the elevated frame 1 saves workshop floor space, adapts to the compact layout of the cat litter production line, and meets the integrated design requirements of the intelligent conveyor line. The suspension frame 4 is rotatably mounted on the mounting chain 3. Unlike the fixed suspension bracket, when the packaging bags are conveyed to the designated work station, the unloading, pouring, and emptying of the cat litter packaging bags can be completed directly through the rotation of the suspension frame 4. The material is loaded into the load frame 5 and placed on the hollow plate 6 connected by the first spring. As the packaging bags filled with cat litter accumulate, the hollow plate 6 moves downward. The movement of the hollow plate 6 drives the trigger rod 7 to move simultaneously. The movement of the trigger rod 7 drives the connecting rod 8 to move and simultaneously pulls the slide rod 9 downward. The downward movement of the slide rod 9 tightens the connecting rope 12. The tension generated by the connecting rope 12 pulls the movable end of the electric push rod 10 downward. The electric push rod 10 is stationary when the power is off. It has no internal self-locking structure, so external force can directly stretch the movable end. When the power is on, the movable end automatically retracts. In normal electric control use, the extension of the movable end of the electric push rod 10 drives the contact block 11 to move. Through the contact of the corners of the suspension frame 4 with the four contact blocks 11, the suspension frame 4 is held and limited, making the suspension frame 4 parallel to the ground. This limits the unnecessary independent rotation of the load frame 5, keeping the cat litter bag in a neat and horizontal position throughout the process. It prevents the bag from tilting, the seal from cracking, and the cat litter from spilling due to the accidental deflection of the load frame 5, thus improving the cleanliness of the production site and the utilization rate of materials. If the cat litter bag leaks due to quality reasons, the leaked cat litter will fall into the collection bag 13 below through the perforated plate 6. The collection bag 13 expands and contracts synchronously with the connecting rod 8, fitting the receiving range throughout the process, greatly improving the spillage collection effect.

[0033] Example 2: Please see Figures 1-9 Based on the above embodiments, in another embodiment of the present invention, the tilting mechanism includes a tilting plate 20 rotatably mounted on the load frame 5, a lever 21 rotatably mounted on the tilting plate 20, a lever 22 rotatably mounted on the tilting plate 20, and a snap-fit ​​groove 23 formed on the tilting plate 20.

[0034] The tilting plate 20 is equipped with a magnetic attraction component inside. A first torsion spring is installed between the lever 21 and the tilting plate 20. The first torsion spring drives the lever 21 to reset. A second torsion spring is installed between the lever 22 and the tilting plate 20. The second torsion spring drives the lever 22 to reset.

[0035] In the above embodiments, the rapid falling impact avoids arousing a large amount of cat litter fine powder, effectively suppresses dust during the unloading process, optimizes the workshop environment, and reduces material loss.

[0036] The tilting mechanism also includes a pull rod 24 slidably installed in the suspension frame 4, a locking block 25 installed on the pull rod 24, a limiting button 26 installed on the tilting plate 20, and a limiting frame 27 installed on the electric push rod 10; a second spring is provided between the pull rod 24 and the suspension frame 4, and the pull rod 24 is reset by the second spring; the contact surface between the locking block 25 and the tilting plate 20 is set as an inclined surface; the locking block 25 matches the locking groove 23.

[0037] In the above embodiments, the tilting plate 20 cannot rotate autonomously without manual unlocking, thus preventing accidental opening and closing of the tilting plate 20 due to equipment vibration, conveying bumps, and material shaking, eliminating accidental opening and material leakage, and adapting to the long-term stable operation of intelligent suspension continuous conveying.

[0038] The tilting mechanism also includes a connecting frame 28 installed below the load-bearing frame 5, an elastic telescopic rod 29 installed on the connecting frame 28, a support plate 210 installed on the elastic telescopic rod 29, and a magnet block 211 installed on the support plate 210; the support plate 210 is provided with an elastic edging; the magnetic components in the tilting plate 20 can be magnetically attached and fixed to the magnet block 211, and the attraction force is set to be able to be overcome by human hand, so as to realize the quick separation and disconnection of the tilting plate 20 and the magnet block 211.

[0039] In the above embodiments, the magnetic attraction is designed to be manually detachable. The unloading station can manually open the magnetic attraction structure as needed, and freely control the opening and closing sequence of the tilting plate 20. This is suitable for production processes of fixed-point unloading and centralized material discharge, and the process adaptability is higher.

[0040] In this embodiment, during operation: the tilting plate 20 is rotatably positioned on the tilting side of the load-bearing frame 5, initially retracting and closing to seal the side opening of the load-bearing frame 5, achieving cavity sealing, and is constrained and fixed by the locking block 25. Specifically: the outer wall of the tilting plate 20 contacts the inclined surface of the locking block 25, causing the locking block 25 to be forcefully driven to move the pull rod 24, while simultaneously compressing the second spring. After the tilting plate 20 is in position, the second spring resets the locking block 25 into the locking groove 23 of the tilting plate 20 to complete the constraint. Pulling the pull rod 24 outwards drives the locking block. 25 is disengaged from the locking slot 23. At this time, the tilting plate 20 can rotate normally. If an external force accidentally touches it, this effect can be triggered in advance. If the tilting plate 20 opens unexpectedly and the internal material falls out, when the contact block 11 holds the load frame 5 level, the movable end of the electric push rod 10 in the power-off state drives the limiting frame 27 to move synchronously. This causes the limiting frame 27 to cover the periphery of the limiting button 26, preventing the limiting button 26 from moving. In other words, the tilting plate 20 cannot move significantly, so it cannot rotate on its own without manual unlocking, thus avoiding equipment vibration and conveyor bumps. To prevent accidental opening and closing of the tilting plate 20 due to material shaking or swaying, and to ensure stable operation of intelligent suspended continuous conveying systems, the electric push rod 10 retracts its movable end after being energized, causing the limiting frame 27 to disengage from the limiting button 26, allowing the suspension frame 4 to rotate for subsequent unloading operations. After release, the tilting plate 20 falls onto the elastically edged support plate 210 due to gravity, and the elastic telescopic rod 29 buffers the closing impact and reduces collision noise. Simultaneously, the magnetic components in the tilting plate 20 adhere to the magnet block 211, strengthening the tilting mechanism. The tilting plate 20 is fixed in a magnetic attraction state that can be manually separated. The magnetic attraction structure can be manually opened as needed at the unloading station, and the opening and closing sequence of the tilting plate 20 can be freely controlled. It is suitable for production processes of fixed-point unloading and centralized discharge, and has higher process adaptability. When the tilting plate 20 guides the packaging bag out, the elastic resistance of the first torsion spring and the second torsion spring through lever 21 and lever 22 slows down the falling speed of the packaging bag, avoids the impact of rapid falling and agitation of a large amount of cat litter powder, effectively suppresses dust in the unloading process, optimizes the workshop environment, and reduces material loss.

[0041] Example 3: Please see Figures 1-9 Based on the above embodiments, in another embodiment of the present invention, the protective mechanism includes a slide 30 installed on the load-bearing frame 5, a baffle 31 slidably installed on the slide 30, and an L-shaped rod 32 installed on the hollow plate 6; the L-shaped rod 32 is provided with toothed grooves.

[0042] The protective mechanism also includes a gear frame 33 mounted on the load-bearing frame 5 and a guide rod 34 mounted on the gear frame 33; the gear frame 33 meshes with the toothed grooves opened on the L-shaped rod 32.

[0043] The protective mechanism also includes a rack 35 that is slidably mounted on the guide rod 34 and a connecting button 36 for connecting the rack 35 and the baffle 31; the rack 35 meshes with the gear carrier 33.

[0044] In the above embodiments, barriers are formed on the left and right sides of the packaging bag to prevent the bag from shifting left and right or slipping and falling off when the conveyor is bumpy or the chain shakes.

[0045] In this embodiment, when the perforated plate 6 moves downward due to pressure, it drives the L-shaped rod 32 to move synchronously. The L-shaped rod 32 moves through its own toothed groove, causing the gear of the gear frame 33 to rotate clockwise. The clockwise rotation of the gear drives the rack rod 35 to move upward along the guide rod 34. The movement of the guide rod 34 drives the connecting button 36 to move. The movement of the connecting button 36 drives the baffle 31 to move along the slide groove 30, so that the baffles 31 on both sides move synchronously. The higher the material loaded on the perforated plate 6, the higher the baffles 31 on both sides automatically rise, forming a barrier on the left and right sides of the packaging bag to prevent the bag from shifting left and right or slipping and falling off when the conveyor is bumpy or the chain shakes.
