Description

Technical Field

[0001] This utility model relates to a plastic particle unpacking machine, belonging to the field of plastic particle technology. Background Technology

[0002] Plastic particles, also known as plastic granules, are the basic raw material of the plastics processing industry and are widely used in modern industry and daily life. They are made from various high molecular polymers through specific processing technology, and are in the form of regular granules with a diameter of about a few millimeters. The raw materials for these particles come from a variety of sources, including fossil energy such as oil and natural gas, as well as some renewable resources.

[0003] In humid southern regions, due to persistently high air humidity and poor storage conditions, such as poor warehouse ventilation and lack of moisture-proof measures, plastic particles are extremely prone to absorbing moisture. When plastic particles absorb moisture, their internal molecular structure changes, and the particles stick together. Over time, this adhesion becomes more severe, gradually forming lumps. When unpacking these lumps of plastic particles, manual crushing is often required, which is not only inefficient and labor-intensive, but also makes it difficult to ensure uniform particle size, greatly affecting product quality.

[0004] Therefore, it is urgent to improve the plastic pellet unpacking machine to solve the above-mentioned problems. Utility Model Content

[0005] The purpose of this invention is to provide a plastic particle unpacking machine. A roller conveyor transports the packaging bags to the end, where a gripping mechanism grabs and transfers them to a crushing mechanism, greatly improving unpacking efficiency and reducing manual labor intensity. In the crushing mechanism, a drive mechanism drives a fixed-axis toothed roller and a moving-axis toothed roller to rotate stably. By rotating the adjusting screw, the distance between the two toothed rollers can be changed to accommodate plastic particles of different agglomeration sizes. It can effectively handle both small agglomerates and large hard agglomerates. When moisture-absorbing and agglomerated plastic particles enter the crushing chamber, the squeezing action of the fixed-axis toothed roller and the moving-axis toothed roller can crush them according to the particle size requirements of subsequent production, thereby ensuring a smooth production process, ensuring uniform particle size, improving product quality, and reducing the risk of production stoppages caused by particle agglomeration.

[0029] The following will describe in detail the implementation of this application with reference to the accompanying drawings and embodiments, so that the implementation process of how this application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0030] like Figures 1-8As shown, the plastic particle unpacking machine provided in this embodiment includes a roller conveyor 1, a gripping mechanism 2 is provided at the end of the roller conveyor 1, a crushing mechanism 3 is provided on one side of the gripping mechanism 2, and a driving mechanism 4 is installed on the crushing mechanism 3.

[0031] The crushing mechanism 3 includes a crushing frame 31, on which a crushing box 32 is fixedly mounted. A fixed-axis toothed roller 33 is rotatably mounted inside the crushing box 32 via a rotating shaft. A fixed-axis driven pulley 34 is located on one side of the crushing box 32 and is connected to the fixed-axis toothed roller 33 via a rotating shaft. A movable-axis toothed roller 35 is located on one side of the fixed-axis toothed roller 33 and is rotatably mounted inside the crushing box 32 via a rotating shaft. A movable-axis driven pulley 35 is located on the other side of the crushing box 32. The driven pulley 36 is connected to the driven shaft toothed roller 35 via a rotating shaft. Both ends of the driven shaft toothed roller 35 are provided with sliding blocks 37. Each end of the driven shaft toothed roller 35 is rotatably connected to the two sliding blocks 37 via a rotating shaft. A screw 38 is rotatably connected to each sliding block 37. The end of the screw 38 away from the sliding block 37 extends through the crushing box 32 to the outside of the crushing box 32. A rotating ring 39 is fixedly connected to the end of the screw 38 located on the outside of the crushing box 32. The two screws 38... All components are threadedly connected to the crushing chamber 32. The roller conveyor 1 transports the packaging bags containing plastic particles to the end. The gripping mechanism 2 grabs the packaging bags from the roller conveyor 1 and sends them to the crushing mechanism 3. In the crushing mechanism 3, the drive mechanism 4 drives the fixed-axis driven pulley 34 and the moving-axis driven pulley 36 to rotate, thereby driving the fixed-axis toothed roller 33 and the moving-axis toothed roller 35 to rotate in the crushing chamber 32. The fixed-axis toothed roller 33 is fixed in position, while the sliding blocks 37 at both ends of the moving-axis toothed roller 35 can move along the screw 38. The operator rotates the rotating ring 39 to rotate the screw 38, thereby adjusting the distance between the moving-axis toothed roller 35 and the fixed-axis toothed roller 33 to meet the crushing requirements of plastic particles with different agglomeration sizes. When the plastic particles that have absorbed moisture and agglomerated enter the crushing chamber 32, the fixed-axis toothed roller 33 and the moving-axis toothed roller 35 crush the agglomerated particles as required by squeezing, meeting the requirements of subsequent production for the particle size of plastic particles, thereby improving product quality and reducing the risk of production stoppage caused by particle agglomeration.

[0032] Furthermore, such as Figures 1-8 As shown, the crushing frame 31 has two sliding holes 5. The sliding block 37 is slidably disposed inside the sliding hole 5, and a spring 6 is disposed inside the sliding hole 5. One end of the spring 6 is connected to the sliding block 37, and the other end of the spring 6 is connected to the inner end face of the sliding hole 5. The spring 6 is sleeved on the outside of the screw 38. When the moving shaft toothed roller 35 encounters a large agglomerated plastic particle during rotation, the operator rotates the rotating ring 39 on the screw 38. The rotation of the screw 38 pulls the sliding block 37 to slide in the sliding hole 5. The sliding block 37 squeezes the spring 6 sleeved on the outside of the screw 38, causing the moving shaft toothed roller 35 to retract, thereby preventing the equipment from being damaged due to overload.

[0033] Furthermore, such as Figures 1-8 As shown, the drive mechanism 4 includes a fixed-axis drive motor 41 and a moving-axis drive motor 42. Both the fixed-axis drive motor 41 and the moving-axis drive motor 42 are fixedly mounted at both ends of the crushing frame 31 via fixing blocks 43. The output end of the fixed-axis drive motor 41 is fixedly connected to a fixed-axis drive pulley 44 via a rotating shaft. The fixed-axis drive pulley 44 is connected to a fixed-axis driven pulley 34 via a fixed-axis belt 45. The output end of the moving-axis drive motor 42 is fixedly connected to a moving-axis drive pulley 46 via a rotating shaft. The moving-axis drive pulley 46 is connected to a moving-axis driven pulley 36 via a moving-axis belt 47. When the plastic particle unpacking machine starts, the fixed-axis drive motor 41 and the moving-axis drive motor 42 begin to operate. The output shaft of the drive motor 41 drives the fixed-axis drive pulley 44 to rotate. The fixed-axis drive pulley 44 transmits power to the fixed-axis driven pulley 34 through the fixed-axis belt 45, which in turn causes the fixed-axis toothed roller 33 connected to the fixed-axis driven pulley 34 to rotate inside the crushing box 32. At the same time, the output shaft of the drive motor 42 drives the drive pulley 46 to rotate. The drive pulley 46 transmits power to the driven pulley 36 through the drive belt 47, which causes the driven pulley 35 connected to the driven pulley 36 to also start rotating. The relative rotation of the fixed-axis toothed roller 33 and the driven pulley 35 can crush the plastic particles entering the crushing box 32, thereby meeting production needs.

[0034] Furthermore, such as Figures 1-8As shown, a discharge port 7 is provided at the bottom of the crushing box 32, and a feed hopper 8 is installed at the top of the crushing box 32. A cutting mechanism 9 is provided on the feed hopper 8. The cutting mechanism 9 includes a cutting motor 91, which is fixedly installed on one side of the feed hopper 8. The output end of the cutting motor 91 is fixedly connected to a cutting shaft 92. The end of the cutting shaft 92 away from the cutting motor 91 passes through the feed hopper 8 and extends into the interior of the feed hopper 8. The end of the cutting shaft 92 located inside the feed hopper 8 is rotatably connected to the inner end face of the feed hopper 8. Several evenly distributed cutters 93 are installed on the cutting shaft 92. When the plastic particle unpacking machine is running, the packaging bags containing plastic particles are conveyed by the roller conveyor 1 and sent to the crushing mechanism 3 by the gripping mechanism 2. The packaging bags to be processed enter the feed hopper 8. The cutting mechanism 9 is started, and the cutting motor 91 drives the cutting shaft 92 to rotate. Several cutters 93 on the shaft rotate at high speed. The cutters 93 cut the packaging bags entering the feed hopper 8, tearing the packaging bags and releasing the plastic particles inside. The plastic particles flowing out of the packaging bags after being cut enter the crushing box 32. In the crushing box 32, the fixed shaft toothed roller 33 and the moving shaft toothed roller 35 rotate under the drive mechanism 4 to crush the plastic particles. The crushed plastic particles are finally discharged from the discharge port 7, completing the entire unpacking and crushing process. The cutting mechanism 9 effectively assists in separating the plastic particles from the packaging bags, thereby improving the working efficiency of the unpacking machine.

[0035] Furthermore, such as Figures 1-8As shown, the gripping mechanism 2 includes a gripping frame 21, on which a servo motor 22 is mounted. An active rotating shaft 23 is fixedly mounted at the output end of the servo motor 22. The end of the active rotating shaft 23 away from the servo motor 22 passes through the gripping frame 21 and is fixedly connected to an active sprocket 24. A driven sprocket 25 is provided on one side of the active sprocket 24. The driven sprocket 25 is rotatably mounted on the gripping frame 21 via a driven rotating shaft 26. The active sprocket 24 and the driven sprocket 25 are connected by a chain 27. A slide rail 28 is provided on the outer side of the chain 27 and is fixedly mounted on the gripping frame 21. Several equidistantly distributed moving blocks 29 are mounted on the chain 27. One end of each of several movable blocks 29 is slidably connected to the slide rail 28, and an electric push rod 210 is fixedly installed on each movable block 29. The output end of the electric push rod 210 is fixedly connected to a connecting plate 211. Two double-headed cylinders 212 are installed on the connecting plate 211. The two double-headed cylinders 212 are respectively located on both sides of the electric push rod 210, and the two output ends of the double-headed cylinders 212 are hinged to grippers 213. Several grippers 213 are hinged to the connecting plate 211 through a rotating shaft. A collection box 10 is provided below the gripping frame 21. When the plastic particle unpacking machine is working, the roller conveyor 1 transports the packaging bag containing plastic particles to the end. At this time, the gripping mechanism 2 starts operating, the servo motor 22 starts, driving the active shaft 23 and the active sprocket 24 to rotate. The active sprocket 24 drives the driven sprocket 25 to rotate through the chain 27. The slide rail 28 on the outer side of the chain 27 guides the moving block 29 on the chain 27, allowing the moving block 29 to slide along the slide rail 28. The electric push rod 210 on the moving block 29 can extend and retract to adjust the height position of the connecting plate 211. When the moving block 29 moves to the appropriate position with the chain 27, the electric push rod 210 extends, allowing the connecting plate 211 to approach. Next, the double-headed cylinder 212 actuates, and its two output ends push the gripper 213 to rotate around the hinge point with the connecting plate 211, thereby causing the gripper 213 to close and grab the packaging bag. After the grabbing is completed, the electric push rod 210 retracts, and the chain 27 continues to drive the moving block 29 to move, transferring the packaging bag to the crushing mechanism 3. After the unpacking is completed, the packaging bag falls into the collection box 10 below the gripping frame 21, thus realizing the grabbing, transfer and collection of the packaging bag, thereby ensuring the efficient operation of the unpacking machine and improving the unpacking efficiency.

[0036] Furthermore, such as Figures 1-8 As shown, a baffle 11 is installed at the end of the roller conveyor 1. The baffle 11 at the end of the roller conveyor 1 can block the packaging bag containing plastic particles from continuing to move forward, ensuring that the gripping mechanism 2 can accurately grip the bag, preventing the packaging bag from leaving the conveying range, and ensuring that the unpacking process is carried out in an orderly manner.

[0037] like Figures 1-8 As shown, the principle of the plastic particle unpacking machine provided in this embodiment is as follows:

[0038] Roller conveyor 1 transports the packaging bags containing plastic particles to the end. At this time, the gripping mechanism 2 starts to operate, starting the servo motor 22 to drive the drive sprocket 24 to rotate via the drive shaft 23. The drive sprocket 24 drives the driven sprocket 25 to rotate via the chain 27. As the chain 27 moves, it drives the moving block 29 to slide along the slide rail 28. When the moving block 29 moves to the appropriate position with the chain 27, the electric push rod 210 extends, bringing the connecting plate 211 closer to the packaging bag. Then, the double-headed cylinder 212 is activated, and its two output ends push the gripper. 213 rotates around the hinge point with the connecting plate 211, causing the gripper 213 to close and grab the packaging bag. After grabbing, the electric push rod 210 retracts, and the chain 27 continues to drive the moving block 29 to move, transferring the packaging bag to the crushing mechanism 3 for unpacking. At this time, the packaging bag to be processed enters the feed hopper 8, and the cutting mechanism 9 is started. The cutting motor 91 runs, driving the cutting shaft 92 to rotate. Several cutters 93 on it rotate at high speed. The cutters 93 cut the packaging bag entering the feed hopper 8, tearing the packaging bag and allowing the plastic particles inside to be extracted. The plastic particles, after being cut and flowing out of the packaging bag, enter the crushing chamber 32. Then, the fixed-axis drive motor 41 and the moving-axis drive motor 42 start to operate. The output shaft of the fixed-axis drive motor 41 drives the fixed-axis drive pulley 44 to rotate. The fixed-axis drive pulley 44 transmits power to the fixed-axis driven pulley 34 through the fixed-axis belt 45, thereby causing the fixed-axis toothed roller 33 connected to the fixed-axis driven pulley 34 to rotate inside the crushing chamber 32. At the same time, the output shaft of the moving-axis drive motor 42 drives the moving-axis drive pulley 46 to rotate. The pulley 46 transmits power to the driven pulley 36 of the driven shaft via the driven shaft belt 47, causing the driven shaft toothed roller 35 connected to the driven shaft toothed roller 36 to also start rotating. The relative rotation of the fixed shaft toothed roller 33 and the driven shaft toothed roller 35 crushes the plastic particles entering the crushing box 32. The operator can also adjust the distance between the driven shaft toothed roller 35 and the fixed shaft toothed roller 33 by rotating the rotating ring 39 to adapt to the crushing requirements of plastic particles with different agglomeration sizes. The crushed plastic particles are finally discharged from the discharge port 7.

[0039] If certain terms are used in the specification and claims to refer to specific components, those skilled in the art will understand that hardware manufacturers may use different names to refer to the same component. This specification and claims do not distinguish components based on differences in name, but rather on differences in function. The term "comprising" as used throughout the specification and claims is an open-ended term and should be interpreted as "comprising but not limited to." "Approximately" means that within an acceptable margin of error, those skilled in the art can solve the technical problem and substantially achieve the technical effect within a certain margin of error.
