Description

Technical Field

[0001] This utility model relates to the field of bag-turning machine technology, specifically a bag-turning machine. Background Technology

[0002] A bag-turning machine is a type of mechanical equipment used in packaging, logistics, and raw material processing industries. Its main function is to turn over and flip packaging bags (such as upright bags) to allow the material inside to flow out smoothly or meet the requirements of subsequent processes (such as pressing and shaping, rejecting defective products, and palletizing). However, a drawback is that manual turning of the bags is still required during transport, which can lead to worker fatigue and increased workload over time. To address this, existing technology (Chinese patent application number: 202320767555.3, authorized announcement date: 2023-11-14) discloses an automatic bag-turning machine. After the bag enters the frame, guide rods and limiting rods prevent the bag from tipping over, ensuring the bag is transported upright onto the conveyor rollers. At this point, a drive cylinder extends its telescopic shaft, from... The support rod lifts, causing the follower rod to rise, which in turn lifts the follower pulley, which in turn lifts the conveyor belt. Once the conveyor belt contacts the material bag, it lifts the bag, separating it from the conveyor rollers. At this point, the drive motor starts, rotating the drive rod, which in turn rotates the drive pulley, which in turn moves the conveyor belt, causing the bag to move towards the limiting rod. When the bag contacts the limiting rod, the limiting rod pushes against the bag, causing it to tip over, thus changing the bag from an upright position to a horizontal one. The bag is then transported to the next process via the conveyor belt, achieving a quick and simple tipping process that reduces labor. After the bag is transported, the cylinder returns to its initial state, causing the conveyor belt to fall back to its initial position, preventing interference with the transport of the next bag.

[0003] Existing technology involves using a drive cylinder to lift a support rod, which in turn lifts a follower rod, causing the bag to tilt. However, the upright bag may shift left or right during transport due to the lack of lateral restraint, preventing the bag-pushing mechanism from accurately aligning with the center of the bag. This results in the tilting direction deviating from the preset trajectory. Furthermore, the impact force during bag tilting can easily damage the inclined plate and cause material to spill out of the packaging, damaging the bag and affecting work efficiency. Therefore, we have proposed a bag-tilting machine that can effectively solve these problems. Utility Model Content

[0004] The purpose of this utility model is to provide a bag-turning machine to solve the problems mentioned in the background art, such as the lack of lateral restraint during the conveying of upright bags, which may cause them to shift left and right, making it impossible for the bag-pushing mechanism to accurately align with the center of the bag, resulting in the turning direction deviating from the preset trajectory. At the same time, when the bag is tilted, the impact force can easily damage the inclined plate and cause the material to rush out of the packaging, resulting in damage to the bag and affecting work efficiency.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a packing machine, comprising a frame and a housing, wherein a conveyor belt assembly is mounted on the top of the frame, a three-phase asynchronous motor is fixed to the lower right side of the frame, and a synchronous belt conveyor mechanism is mounted on the top of the housing; further comprising: a driving roller and a driven roller are respectively arranged on the left and right sides inside the synchronous belt conveyor mechanism, a cylinder is bolted to the bottom of the housing, the synchronous belt conveyor mechanism is connected to the cylinder via a connecting piece, baffles are bolted to the front and rear sides of the upper surface of the frame, and an inclined plate is connected between the two baffles, a fixed cylinder is fixed to the left side of the upper surface of the frame, and a movable rod is connected to the top of the fixed cylinder, and a buffer spring is installed between the bottom of the movable rod and the inner wall of the fixed cylinder.

[0006] Preferably, the conveyor belt assembly and the synchronous belt conveyor mechanism are arranged vertically and alternately, the conveying directions of the conveyor belt assembly and the synchronous belt conveyor mechanism are perpendicular, and the raised plane of the synchronous belt conveyor mechanism is higher than the plane of the conveyor belt assembly. The three-phase asynchronous motor is connected to the conveyor belt assembly through a pulley assembly.

[0007] Preferably, the connecting piece is arranged in a "V" shape, and both ends of the connecting piece are hinged to the driven roller and the frame on the synchronous belt conveyor mechanism, respectively. The piston rod on the cylinder is hinged to the middle of the connecting piece.

[0008] Preferably, the inclined plate is rotatably connected to the left side between the two frames via a shaft, and the two baffles are symmetrically distributed on the upper surface of the frame about the center point of the conveyor belt assembly.

[0009] Preferably, the bottom of the movable rod extends into the interior of the fixed cylinder, and the movable rod and the fixed cylinder are slidably connected, and the lower surfaces of the top inclined plates of the movable rod are hinged.

[0010] Preferably, the inclined plate forms a buffer structure through a fixed cylinder, a movable rod, and a buffer spring.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: This bag-turning machine adopts a novel structural design, the specific details of which are as follows:

[0012] (1) The bagged powder is placed vertically on the synchronous belt conveyor. When it is conveyed above the conveyor belt assembly, the cylinder piston rod pulls one end of the lifting conveyor downward through the connecting plate. The synchronous belt conveyor rotates downward. The plane on one side of the synchronous belt conveyor is lower than the conveyor belt assembly, while the plane on the other side is higher than the conveyor belt assembly. The powder bag is tilted by the side that is higher than the conveyor belt assembly. Since the bottom of the powder bag falls on the conveyor belt assembly, and the conveyor belt assembly is always in the conveying state, the bottom of the powder bag is under force, and the powder bag is overturned. Furthermore, by utilizing the cooperation between the synchronous belt drive mechanism and the conveyor belt assembly, the powder bag can adjust the conveying direction, which is convenient for the subsequent grabbing of the powder bag.

[0013] (2) The lifting conveyor is driven by a combination of cylinder and connecting plate to lift one end. The action is fast (single overturning time < 5 seconds). The overturning angle can be controlled by adjusting the cylinder stroke. The conveyor belt transmits materials under the action of the drive shaft and driven shaft. Its surface pattern and other designs can increase friction and prevent material from sliding. The reducer is connected to the three-phase asynchronous motor to reduce the output speed of the three-phase asynchronous motor and increase the torque at the same time, so that the power output meets the working requirements of the equipment.

[0014] (3) The two baffles on the conveyor belt assembly can limit the position of the packaging bag and prevent it from deviating. At the same time, the inclined plate can guide the upright packaging bag to slide along the inclined plane during the pushing process, avoiding excessive impact force or loss of control of the tilting direction caused by vertical tipping. Meanwhile, the movable rod will move downward under the weight of the packaging bag and squeeze the buffer spring. At this time, the elasticity of the buffer spring itself can effectively reduce the impact force, protect the inclined plate, prevent the material from rushing out due to inertia, and avoid damage to the packaging.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1-6 This utility model provides the following technical solution: a repackaging machine;

[0024] Example 1: To address the problem in the prior art where upright material bags, lacking lateral restraint during transport, may shift left or right, causing the bag-pushing mechanism to fail to accurately align with the bag's center, resulting in the tipping direction deviating from the preset trajectory, and the impact force during tipping easily damaging the inclined plate 12 and causing material to spill out of the packaging, thus damaging the material bag and affecting work efficiency, the following solution is disclosed. Please refer to the following for details. Figures 1-5 As shown, the system includes a frame 1 and a frame 5. A conveyor belt assembly 2 is mounted on the top of the frame 1, and a three-phase asynchronous motor 3 is fixed to the lower right side of the frame 1. A synchronous belt conveyor mechanism 4 is mounted on the top of the frame 5. The system also includes: a drive roller 6 and a driven roller 7 are respectively arranged on the left and right sides inside the synchronous belt conveyor mechanism 4. The conveyor belt assembly 2 and the synchronous belt conveyor mechanism 4 are arranged vertically and alternately. The conveying directions of the conveyor belt assembly 2 and the synchronous belt conveyor mechanism 4 are perpendicular, and the raised plane of the synchronous belt conveyor mechanism 4 is higher than the plane of the conveyor belt assembly 2. The three-phase asynchronous motor 3 is connected to the conveyor belt assembly 2 through a pulley assembly. A cylinder 8 is bolted to the bottom of the frame 5. The synchronous belt conveyor mechanism 4 is connected to the cylinder 8 through a connecting piece 9. The connecting piece 9 is V-shaped, and both ends of the connecting piece 9 are hinged to the driven roller 7 on the synchronous belt conveyor mechanism 4 and the frame 5, respectively. The piston rod on the cylinder 8 is hinged to the middle of the connecting piece 9.

[0025] Initially, the plane of the synchronous belt conveyor 4 of the lifting conveyor is higher than the plane of the conveyor belt assembly 2 of the conveyor, creating a height difference. The upright powder bags are placed on the synchronous belt conveyor 4 manually or by upstream equipment and conveyed towards the conveyor. The bagged powder bags are vertical and placed on the synchronous belt conveyor 4 for transport. When the bag reaches above the conveyor belt assembly 2, the piston rod of the cylinder 8 pulls one end of the lifting conveyor downwards via the connecting piece 9, causing the synchronous belt conveyor 4 to rotate downwards. One side of the synchronous belt conveyor 4 is lower than the conveyor belt assembly 2, while the other side is higher. The side higher than the conveyor belt assembly 2 causes the powder bags to tip over. Since the bottom of the powder bags falls onto the conveyor belt assembly... 2. Simultaneously, the conveyor belt assembly 2 is always in the conveying state. The bottom of the powder bag is subjected to force, causing the powder bag to tip over. The synchronous belt drive mechanism 4 and the conveyor belt assembly 2 work together to adjust the conveying direction of the powder bag, facilitating subsequent grabbing of the powder bag. The device drives the lifting conveyor to rise and fall at one end through a combination of cylinder 8 and connecting plate 9. The action is rapid (single tipping time < 5 seconds), and the tipping angle can be precisely controlled by adjusting the stroke of cylinder 8. The conveyor belt assembly 2 is driven by the drive shaft and driven shaft to transport materials. Its surface texture design increases friction to prevent material slippage. At the same time, the reducer is connected to the three-phase asynchronous motor 3, which can reduce the motor output speed and increase the torque, so that the power output is adapted to the working requirements of the equipment.

[0026] Example 2: Unlike Example 1, this example utilizes two baffles 11 to limit the position of the packaging bag and prevent it from shifting. See details... Figure 1 and Figure 6 As shown, baffles 11 are bolted to both the front and rear sides of the upper surface of the frame 1, and an inclined plate 12 is connected between the two baffles 11. The inclined plate 12 is rotatably connected to the left side between the two frames 1 via a shaft. The two baffles 11 are symmetrically distributed on the upper surface of the frame 1 about the center point of the conveyor belt assembly 2.

[0027] The two baffles 11 on the conveyor belt assembly 2 can effectively limit the position of the packaging bag and prevent it from shifting during the conveying process; the matching inclined plate 12 provides an inclined support surface for the upright packaging bag, guiding it to slide smoothly along the inclined surface during the tipping process, avoiding excessive impact force or loss of control of the tipping direction due to vertical tipping.

[0028] Example 3: Unlike Example 2, this example utilizes the elasticity of the buffer spring 10 itself to effectively reduce impact force, protect the inclined plate 12, prevent materials from being ejected due to inertia, and avoid packaging damage. See details for further information. Figure 1 and Figure 6As shown, a fixed cylinder 13 is fixed on the left side of the upper surface of the frame 1, and a movable rod 14 is connected to the top of the fixed cylinder 13. A buffer spring 10 is installed between the bottom of the movable rod 14 and the inner wall of the fixed cylinder 13. The bottom of the movable rod 14 extends into the interior of the fixed cylinder 13, and the movable rod 14 and the fixed cylinder 13 are slidably connected. The lower surface of the top inclined plate 12 of the movable rod 14 is hinged. The inclined plate 12 forms a buffer structure through the fixed cylinder 13, the movable rod 14 and the buffer spring 10.

[0029] When the packaging bag falls onto the inclined plate 12, the movable rod 14 will move downwards due to the weight of the packaging bag and squeeze the buffer spring 10. At this time, the elasticity of the buffer spring 10 itself can effectively reduce the impact force, protect the inclined plate 12, prevent the material from rushing out due to inertia, and avoid damage to the packaging.
