Description

Technical Field

[0001] This invention relates to the field of bag breaking and unpacking technology, specifically to an automatic bag breaking and unpacking machine for powder materials made of plastic-coated steel pipes. Background Technology

[0002] The automatic bag-breaking and unpacking machine for plastic-coated steel pipe powder is an intelligent device specifically designed for the powder feeding stage in the production process of plastic-coated steel pipes. By integrating mechanical automation, sensor detection, and intelligent control technologies, it can automatically complete the entire process of grabbing packaging bags, accurately positioning them, breaking them in a dust-free manner, and efficiently unloading the powder. It replaces the traditional manual bag-breaking method, significantly improving feeding efficiency and operational safety. At the same time, the sealed design and dust collection system effectively prevent powder leakage and pollution, ensuring a clean production environment. It also has the ability to adapt to different bag types and powder characteristics, making it a key piece of equipment for achieving continuous and automated operation of plastic-coated steel pipe production lines.

[0003] While existing automatic bag-breaking and unpacking machines for plastic-coated steel pipe powder can complete basic unpacking tasks, they generally suffer from two major functional defects: First, they lack an intelligent posture correction mechanism for the packaging bags. When the bags tilt, wrinkle, or shift due to vibration or collision during transport, the system cannot automatically adjust the bag position, resulting in cutting position deviations and easily causing problems such as incomplete bag breaking or bag damage and powder leakage. Second, they are not equipped with an active cleaning device for powder adhering to the surface of the cutting blades. As the unpacking operation continues, the powder gradually adheres to the blade surface, forming a hard shell. This not only reduces cutting efficiency and increases energy consumption but may also cause the blades to break due to uneven stress, affecting the stability and service life of the equipment.

[0004] Therefore, we propose an automatic bag-breaking and unpacking machine for plastic-coated steel pipe powder. Summary of the Invention

[0005] The purpose of this invention is to provide an automatic bag-breaking and unpacking machine for plastic-coated steel pipe powder, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an automatic bag-breaking and unpacking machine for plastic-coated steel pipe powder, comprising:

[0007] Vertical plates, with a support plate fixedly connected between the two vertical plates;

[0008] A cutting mechanism, the cutting mechanism including a moving groove, the moving groove being opened inside the center of the support plate, a reciprocating screw being rotatably mounted on the top of the support plate, and a moving block being meshed with the outside of the reciprocating screw;

[0009] The recycling mechanism includes a drive rod, which is installed between the two support plates and is fixedly connected to the bottom of the telescopic rod at its center. A sliding groove is provided inside the vertical plate, and a sliding block is slidably installed inside the sliding groove.

[0010] Preferably, rollers are symmetrically rotated between the two vertical plates, and conveyor belts are symmetrically mounted on the outer sides of the rollers. The conveyor belts have through holes inside. The powder packaging bags to be unpacked are placed on the conveyor belt, and the symmetrically rotating rollers between the two vertical plates drive the conveyor belt to smoothly transport the packaging bags to the processing area.

[0011] Preferably, rotating rods are symmetrically mounted between the two vertical plates. Squeezing rollers are mounted on the outer sides of the rotating rods. Pulleys are mounted at one end of each rotating rod, and a connecting belt connects the pulleys. A drive motor is mounted at one end of one rotating rod, and the output of the drive motor is fixedly connected to the rotating rod. The rotating rods rotate under the drive motor's influence, and the pulleys, via the connecting belt, enable synchronous operation of the two rotating rods. The squeezing rollers on the outer sides of the rotating rods apply slight pressure to the packaging bag, both to secure the bag and prevent slippage during cutting, and to assist in subsequent powder unloading.

[0012] Preferably, the cutting mechanism further includes a telescopic rod. The telescopic rod is fixedly connected to the bottom of the moving block, and a cutting blade is fixedly connected to the other end of the telescopic rod. A rotary motor is installed at one end of the reciprocating screw, and the output end of the rotary motor is fixedly connected to the reciprocating screw. The rotary motor drives the reciprocating screw to rotate on the top of the support plate. The moving block, which meshes with the reciprocating screw, moves reciprocally in a linear motion along the moving groove in the center of the support plate. The telescopic rod at the bottom of the moving block drives the cutting blade to descend to a suitable height, and moves synchronously with the moving block to complete the precise cutting of the packaging bag, ensuring that the bag structure is controlled to be destroyed, so that the internal powder falls through the through hole opened in the conveyor belt under the action of gravity.

[0013] Preferably, the recycling mechanism further includes fixed rods, with both ends of the drive rod fixedly connected to sliding blocks. Fixed rods are symmetrically fixedly connected to the bottom of the support plate, and a fixed plate is fixedly connected to the bottom of each fixed rod. A brush plate is installed on the surface of the fixed plate near the cutting blade. When the cutting blade moves to its end, the sliding block slightly raises the drive rod and telescopic rod along the inclined groove, causing the cutting blade to just contact the brush plate on the surface of the fixed plate. During the reverse movement, the brush plate thoroughly cleans the powder adhering to the blade surface.

[0014] Preferably, one end of the sliding groove is inclined to facilitate the cleaning of its outer surface by the passing of the cutting blade.

[0015] Preferably, a bidirectional threaded rod is rotatably mounted between the two vertical plates, and a bracket is slidably mounted inside the two vertical plates. Engaging blocks are meshed at both ends of the bidirectional threaded rod, and the bottom of the bracket is fixedly connected to the engaging blocks. A limiting plate is fixedly connected to the top of the bracket. A stepping motor is mounted on one side of each vertical plate, and the output end of the stepping motor passes through the interior of the vertical plate and is fixedly connected to the bidirectional threaded rod. The stepping motor drives the bidirectional threaded rod to rotate, causing the engaging blocks at both ends to move the bracket within the vertical plate. The limiting plate at the top of the bracket adaptively adjusts its spacing according to the size of the packaging bag, precisely limiting and correcting the bag's posture to prevent tilting or displacement due to vibration or collision, ensuring the accuracy of subsequent cutting positions.

[0016] Preferably, a recycling bin is fixedly connected to the bottom of the vertical plate, and a discharge port is provided at the front end of the recycling bin.

[0017] Preferably, a control panel is installed on one side of the recycling bin, and the drive motor, rotation motor and progress motor are all electrically controlled and connected by the control panel.

[0018] Compared with the prior art, the beneficial effects of the present invention are:

[0019] Improve cutting accuracy and material feeding efficiency: The reciprocating screw of the cutting mechanism drives the moving block to move the cutting blade in a reciprocating motion. Combined with the telescopic rod to adjust the cutting height, the packaging bag can be precisely cut, ensuring that the bag structure is quickly and controllably destroyed. The internal powder flows out smoothly through the conveyor belt through the holes under the assistance of gravity or extrusion rollers, reducing powder residue and significantly improving material feeding efficiency.

[0020] Ensuring blade sharpness and reducing energy consumption: The recycling mechanism, through the cooperation of the brush plate and the cutting blade, promptly cleans the powder adhering to the surface of the blade during its reciprocating movement, preventing the powder from forming hard lumps, ensuring that the cutting edge always remains sharp, reducing cutting resistance, reducing equipment operating energy consumption, and extending the blade's service life.

[0021] Optimize bag posture and cutting stability: By using a progressive motor to drive a bidirectional threaded rod to adjust the spacing of the limiting plates, the bag posture can be adaptively corrected according to the size of the packaging bag, avoiding bag tilting or offset caused by vibration and collision during the conveying process, preventing incomplete bag breaking or powder leakage caused by cutting position deviation, and improving the stability of the cutting operation.

[0022] Achieving efficient powder recycling and environmental cleanliness: The powder after cutting and the residual powder from brush cleaning fall into the recycling bin and are discharged centrally through the discharge port, reducing powder waste and leakage pollution. Combined with the coordinated operation of the equipment, it ensures a clean production environment and meets the environmental protection requirements of intelligent production.

[0030] 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.

[0031] Please see Figure 1-6 An automatic bag-breaking and unpacking machine for plastic-coated steel pipe powder, comprising:

[0032] Vertical plate 1, with a support plate 2 fixedly connected between the two vertical plates 1;

[0033] The cutting mechanism 31 includes a moving groove 11. The moving groove 11 is opened inside the center of the support plate 2. A reciprocating screw 12 is rotatably installed on the top of the support plate 2. A moving block 13 is meshed with the outside of the reciprocating screw 12.

[0034] The recycling mechanism 32 includes a drive rod 16, which is installed between the two support plates 2 and is fixedly connected to the bottom of the telescopic rod 14 at its center. A sliding groove 17 is provided inside the vertical plate 1, and a sliding block 18 is slidably installed inside the sliding groove 17.

[0035] Please see Figure 3 A roller 3 is symmetrically mounted between the two vertical plates 1, and a conveyor belt 4 is symmetrically mounted on the outside of the roller 3. The conveyor belt 4 has through holes 5 inside. The powder packaging bags to be unpacked are placed on the conveyor belt 4. The roller 3, which rotates symmetrically between the two vertical plates 1, drives the conveyor belt 4 to operate, smoothly transporting the packaging bags to the processing area.

[0036] Please see Figure 4 A rotating rod 6 is symmetrically mounted between two vertical plates 1. A squeezing roller 7 is mounted on the outer side of each rotating rod 6. A pulley 8 is mounted at one end of each rotating rod 6, and a connecting belt 9 is installed between the pulleys 8. A drive motor 10 is mounted at one end of each rotating rod 6, and the output end of the drive motor 10 is fixedly connected to the rotating rod 6. The rotating rod 6 rotates under the drive of the drive motor 10. The pulleys 8 and the connecting belt 9 enable synchronous operation of the two rotating rods 6. The squeezing roller 7 on the outer side of the rotating rod 6 slightly squeezes the packaging bag, both fixing the bag to prevent slippage during cutting and assisting in subsequent powder unloading.

[0037] Please see Figure 4 The cutting mechanism 31 also includes a telescopic rod 14. The telescopic rod 14 is fixedly connected to the bottom of the moving block 13, and a cutting blade 15 is fixedly connected to the other end of the telescopic rod 14. A rotary motor 19 is installed at one end of the reciprocating screw 12, and the output end of the rotary motor 19 is fixedly connected to the reciprocating screw 12. The rotary motor 19 drives the reciprocating screw 12 to rotate on the top of the support plate 2. The moving block 13, which meshes with the reciprocating screw 12, moves reciprocally in a linear motion along the moving groove 11 in the center of the support plate 2. The telescopic rod 14 at the bottom of the moving block 13 drives the cutting blade 15 to descend to a suitable height. The cutting blade 15 moves synchronously with the moving block 13 to complete the precise cutting of the packaging bag, ensuring that the bag structure is destroyed in a controllable manner, so that the powder inside falls through the through hole 5 opened in the conveyor belt 4 under the action of gravity.

[0038] Please see Figure 5The recycling mechanism 32 also includes a fixed rod 20. The two ends of the drive rod 16 are fixedly connected to the sliding block 18. The bottom of the support plate 2 is symmetrically fixedly connected to the fixed rod 20, and the bottom of the fixed rod 20 is fixedly connected to a fixed plate 21. A brush plate 22 is installed on the surface of the fixed plate 21 near the cutting blade 15. When the cutting blade 15 moves to its end, the sliding block 18 drives the drive rod 16 and the telescopic rod 14 to rise slightly along the inclined groove, so that the cutting blade 15 just contacts the brush plate 22 on the surface of the fixed plate 21. During the reverse movement, the brush plate 22 thoroughly cleans the powder adhering to the blade surface.

[0039] Please see Figure 4 The sliding groove 17 has an inclined shape at one end, which facilitates the cutting blade 15 to pass through and clean its outer surface.

[0040] Please see Figure 6 A bidirectional threaded rod 23 is rotatably mounted between the two vertical plates 1. A bracket 24 is slidably mounted inside the two vertical plates 1. Engaging blocks 25 are meshed with the outer ends of the bidirectional threaded rod 23, and the bottom of the bracket 24 is fixedly connected to the engaging blocks 25. A limiting plate 26 is fixedly connected to the top of the bracket 24. A stepping motor 27 is mounted on one side of each vertical plate 1, and the output end of the stepping motor 27 passes through the interior of the vertical plate 1 and is fixedly connected to the bidirectional threaded rod 23. The stepping motor 27 drives the bidirectional threaded rod 23 to rotate, causing the engaging blocks 25 at both ends to move the bracket 24 within the vertical plate 1. The limiting plate 26 at the top of the bracket 24 adaptively adjusts its spacing according to the size of the packaging bag, precisely limiting and correcting the posture of the bag to prevent tilting or displacement of the bag due to vibration or collision, ensuring the accuracy of the subsequent cutting position.

[0041] Please see Figure 1 The bottom of the vertical plate 1 is fixedly connected to a recycling bin 28, and the front end of the recycling bin 28 is provided with a discharge port 29.

[0042] Please see Figure 1 A control panel 30 is installed on one side of the recovery bin 28, and the drive motor 10, the rotation motor 19, and the stepping motor 27 are all electrically controlled and connected by the control panel 30.

[0043] Working Principle: First, after the operator starts the equipment via the control panel 30, the powder packaging bag to be unpacked is placed on the conveyor belt 4. The rollers 3, which rotate symmetrically between the two vertical plates 1, drive the conveyor belt 4 to smoothly transport the packaging bag to the processing area. During the conveying process, the advance motor 27 drives the bidirectional threaded rod 23 to rotate, causing the meshing blocks 25 at both ends to drive the bracket 24 to slide within the vertical plate 1. The limiting plate 26 at the top of the bracket 24 adaptively adjusts the spacing according to the size of the packaging bag, precisely limiting and correcting the posture of the bag, avoiding tilting or displacement of the bag due to vibration or collision, and ensuring the accuracy of the subsequent cutting position. When the packaging bag is transported to the bottom of the cutting mechanism 31, the rotating rod 6 rotates under the drive of the drive motor 10. The pulley 8 connects to the belt 9 to achieve synchronous operation of the two rotating rods 6. The squeezing roller 7 on the outside of the rotating rod 6 slightly squeezes the packaging bag, which not only fixes the bag to prevent slippage during cutting, but also assists in the subsequent unloading of powder. At this time, the cutting mechanism 31 starts to work. The rotating motor 19 drives the reciprocating screw 12 to rotate on the top of the support plate 2. The moving block 13, which meshes with the reciprocating screw 12, moves in a reciprocating linear motion along the moving groove 11 in the center of the support plate 2. The telescopic rod 14 at the bottom of the moving block 13 drives the cutting blade 15 to descend to a suitable height. The cutting blade moves synchronously with the moving block 13 to complete the precise cutting of the packaging bag, ensuring that the bag structure is destroyed in a controllable manner, so that the powder inside falls through the through hole 5 opened by the conveyor belt 4 under the action of gravity. After the cutting operation is completed, the recycling mechanism 32 is activated. The drive rod 16, which is fixedly connected to the bottom of the telescopic rod 14, moves with the moving block 13. The sliding blocks 18 at both ends slide in the sliding groove 17 inside the vertical plate 1. Since one end of the sliding groove 17 is inclined, when the cutting blade 15 moves to the end, the sliding block 18 drives the drive rod 16 and the telescopic rod 14 to rise slightly along the inclined groove section, so that the cutting blade 15 just contacts the brush plate 22 on the surface of the fixed plate 21. During the reverse movement, the brush plate 22 thoroughly cleans the powder adhering to the blade surface to avoid the formation of hard lumps, ensuring that the cutting edge is always sharp and reducing cutting resistance and energy consumption. The cleaned powder and the powder flowing out of the bag after cutting fall into the recycling bin 28 at the bottom of the vertical plate 1, and are finally discharged through the discharge port 29 at the front end of the recycling bin 28, realizing the efficient recycling and utilization of powder.
