Description

Technical Field

[0001] The invention relates to the technical field of environmental protection equipment, in particular to a three-separation recycling machine for plastic bottles. Background Art

[0002] At present, most of the plastic bottle recycling equipment on the market adopts a simple conveyor belt design. Users put the plastic bottles directly into the entrance of the recycling equipment, and then the plastic bottles are sent into the equipment through the conveyor belt for preliminary collection. However, this traditional recycling method has obvious defects:

[0003] 1. Difficulty in material separation:

[0004] Plastic bottles usually consist of three parts: the bottle cap, the bottle body, and the label on the outside of the bottle body. Due to the different material properties of these three parts, subsequent classification and processing often requires manual and detailed sorting. This not only increases the labor intensity of the staff, but also limits the improvement of recycling efficiency;

[0005] 2. Insufficient space utilization:

[0006] The internal space design of existing recycling machines often fails to fully consider the needs of actual usage scenarios, especially in shopping malls or residential areas with large traffic. The number of plastic bottles collected per day is huge, and frequent manual cleaning is required, further increasing the burden on staff;

[0007] 3. Low enthusiasm of public participation:

[0008] For ordinary people, since they usually only carry one plastic bottle when they go out for outdoor activities and there is a lack of convenient recycling incentives, many people often lack the motivation to actively recycle. This not only leads to the waste of plastic bottle resources, but also affects the popularization and promotion of environmental awareness.

[0009] To sum up, the existing plastic bottle recycling equipment has obvious deficiencies in terms of automation, space optimization and public participation. There is an urgent need for a new type of plastic bottle recycling machine that can overcome the above defects to improve recycling efficiency, reduce labor intensity, and stimulate the public's environmental awareness and enthusiasm for participation. To this end, we propose a plastic bottle three-separation recycling machine. Summary of the invention

DETAILED DESCRIPTION

[0045] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0046] Embodiment 1:

[0047] See also Figure 1-11 The present invention provides a technical solution: a three-separation recycling machine for plastic bottles, comprising a recycling machine body 1, a liquid crystal display screen 11 is arranged on the recycling machine body 1, a compiler is arranged in the liquid crystal display screen 11, and the public can directly operate through the liquid crystal display screen 11, and choose to scan the code for recycling or donate with love. If the scanning code for recycling is chosen, the equipment will give back corresponding environmental protection points according to the number of recycled bottles, and the environmental protection points can be directly consumed. If the donation is chosen with love, part of the income from recycling will be donated to the charity organization, which can greatly increase the enthusiasm of the public to put in plastic bottles. The recycling machine body 1 is provided with an input port 12, and also includes:

[0048] A through pipe 2 is installed in the recycling machine body 1 and communicated with the input port 12. A strip hole 21 is provided at one end of the through pipe 2 close to the input port 12. There are a plurality of strip holes 21 arranged evenly in an annular array on the through pipe 2.

[0049] V-shaped frames 22, the number of which is the same as the number of the strip holes 21, and are mounted on the through pipe 2 via a shaft;

[0050] The bottle filtering mechanism 3 is installed on the through pipe 2 and connected to the V-shaped frame 22. The bottle filtering mechanism 3 restricts the plastic bottle from entering the through pipe 2 only when the bottle mouth faces the input port 12.

[0051] The blocking and picking mechanism 4 is installed on the through pipe 2 and is divided into three parts: an intercepting part 41, a clamping part 42 and a rotating part 43. The intercepting part 41 is used to limit the position of the plastic bottle entering the through pipe 2, the clamping part 42 is used to clamp the bottle cap of the plastic bottle, and the rotating part 43 drives the clamping part 42 and the bottle cap clamped by the clamping part 42 to rotate synchronously after the clamping part 42 clamps the bottle cap, so as to strengthen the connection between the bottle cap and the bottle body, or release the connection between the bottle cap and the bottle body;

[0052] There are two first through holes 23, which are respectively opened at the upper and lower positions of the middle part of the through pipe 2;

[0053] The bottle body clamping mechanism 5 is installed on the through pipe 2 and partially contacts the first through hole 23. The bottle body clamping mechanism 5 clamps and fixes the plastic bottle after passing through the bottle body filtering mechanism 3 and squeezes the bottle body. The axis of the bottle body after clamping is in the same straight line as the axis of the through pipe 2. Under the cooperation of the bottle body clamping mechanism 5 and the blocking and removing mechanism 4, the connection between the bottle cap and the bottle body is strengthened, and then the separation of the bottle cap and the bottle body is achieved by compressing the gas inside the bottle and releasing the connection between the bottle cap and the bottle body.

[0054] There are two second through holes 24, which are respectively opened at the left and right positions of the middle part of the through pipe 2, and the first micro servo motor 25 is installed on the two second through holes 24;

[0055] There are two transmission separation mechanisms 6, which are respectively installed on one of the second through holes 24. The transmission separation mechanism 6 is divided into two parts: a transmission part 61 and a separation part 62. The transmission part 61 is connected to one of the first micro servo motors 25. The separation part 62 provides power in different directions through the forward and reverse steering of the first micro servo motor 25. Under the power of the transmission part 61 in different directions, the separation part 62 applies a forward moving force to the plastic bottle or separates the label on the plastic bottle from the plastic bottle.

[0056] The bottle body filtering mechanism 3 includes a limit block 31 installed on the through pipe 2. The number of the limit blocks 31 is the same as the number of the strip holes 21, and the limit blocks 31 are staggered with the strip holes 21. The bottle body filtering mechanism 3 also includes an electromagnet 32 ​​fixed to one end of the through pipe 2 close to the input port 12. The electromagnet 32 ​​is annular. A magnet ring 33 is sleeved on the through pipe 2. The magnet ring 33 is located between the electromagnet 32 ​​and the limit block 31. The bottle body filtering mechanism 3 also includes an infrared sensor 34 installed on the inner wall of the through pipe 2. When one side of the V-shaped frame 22 is parallel to the through pipe 2, the other side is located inside the through pipe 2 and is inclined. The inclined side of multiple V-shaped frames 22 forms a blunt cone. The infrared sensor 34 is located on the vertical plane where the top surface of the blunt cone is located. The infrared sensor 34 is electrically connected to the electromagnet 32. A slogan 35 is posted around the input port 12.

[0057] like Figure 1 , 7 As shown in , 8, the slogan 35 is a text to guide the public to put the mouth of the plastic bottle toward the device, such as "Please put the mouth of the plastic bottle toward the device", etc. When the public recycles the plastic bottle, they select the recycling method through the LCD screen 11, and then hold the body or tail of the plastic bottle, and first insert the mouth of the plastic bottle into the input port 12. Since the plastic bottle has the characteristics of a small mouth diameter and a large body and bottom diameter, when the mouth of the plastic bottle enters first, the bottle cap at the mouth of the bottle will pass through the small opening formed by the inclined side of the V-shaped frame 22 and be sensed by the infrared sensor 34. Then the infrared sensor 34 sends a signal to the electromagnet 32 ​​to change the direction of the current and generate magnetic attraction to the magnet ring 33. After the magnet ring 33 is attached to the electromagnet 32, the obstruction of the magnet ring 33 is lost, and the V-shaped frame 22 can rotate freely, and the public can continue to insert the plastic bottle;

[0058] If the public first inserts the bottom of the plastic bottle into the input port 12, the larger diameter of the bottle bottom cannot pass through the V-shaped frame 22, and the infrared sensor 34 cannot be triggered. The electromagnet 32 ​​applies a repulsive force to the magnet ring 33, and the magnet ring 33 restricts one side of the V-shaped frame 22. The V-shaped frame 22 that cannot rotate will prevent the plastic bottle from continuing to be put in.

[0059] It should be noted that after the public chooses the recycling method, the recycling machine body 1 will simultaneously give voice reminders to guide the public on how to put the bottles in. If no plastic bottles are detected after a period of time, it will give voice reminders again. If no detection is made for a long time, it will exit the recycling state.

[0060] The intercepting portion 41 includes a groove 411 installed at one end of the through pipe 2 away from the input port 12, a first rotating shaft 412 is installed through the groove 411, a second micro servo motor 414 is fixed to the outer wall of the through pipe 2 through a bracket 413, the output shaft of the second micro servo motor 414 is fixed to the first rotating shaft 412, a first fixing ring 415 is fixed to the first rotating shaft 412 through a connecting plate, the center of the first fixing ring 415 is in the same straight line as the axis of the through pipe 2, a disc 416 is rotatably connected to the first fixing ring 415, a third through hole 417 is opened on the disc 416, the middle part of the third through hole 417 is strip-shaped, and the two end parts are elliptical.

[0061] After the plastic bottle moves to the position of the disc 416 in the through tube 2, the bottle mouth will enter the third through hole 417, and the bottle body cannot pass through due to the obstruction of the disc 416. At this time, the bottle cap of the plastic bottle is located inside the third through hole 417.

[0062] The clamping portion 42 includes a first parallel clamping jaw 421 installed on the disc 416, and the telescopic parts at both ends of the first parallel clamping jaw 421 are fixed with a first L-rod 422, and an arc plate 423 is installed on the first L-rod 422. The two arc plates 423 are arranged opposite to each other and are respectively located at one end of the third through hole 417, and a roller 424 is provided on the inner wall of the arc plate 423. There are a plurality of rollers 424, which are arranged along the inner wall of the arc plate 423 and are all perpendicular to the axis of the through pipe 2.

[0063] The rotating part 43 includes a gear ring 431 sleeved on the disk 416 . A stepper motor 432 is fixed on the first fixing ring 415 . A gear 433 is mounted on the output shaft of the stepper motor 432 . The gear 433 and the gear ring 431 are meshed with each other.

[0064] The bottle body clamping mechanism 5 includes a second parallel clamping jaw 52 fixed to one side of the through pipe 2 through a support rod 51. The second parallel clamping jaw 52 is electrically connected to the second micro servo motor 414. The telescopic parts at both ends of the second parallel clamping jaw 52 are fixed with second L-rods 53. The second L-rods 53 are installed with arc frames 54. The two arc frames 54 respectively block the two first through holes 23. The arc frames 54 are composed of multiple arc rods and two straight rods, one of which connects one end of the arc rod and the other straight rod connects the other end of the arc rod.

[0065] like Figure 7 , 9As shown, when the plastic bottle moves in the through pipe 2 and is blocked by the interception part 41, the force applied to the plastic bottle to move forward eventually changes to apply a certain thrust to the disc 416, and the disc 416 is transmitted to the second micro servo motor 414 through the first fixing ring 415, the connecting plate, and the first rotating shaft 412. The second micro servo motor 414 sends a signal to the second parallel clamp 52, and the second parallel clamp 52 is started to drive the second L rods 53 on both sides to approach each other. The second L rod 53 synchronously drives the arc frame 54 to approach each other to clamp the plastic bottle. After the plastic bottle is clamped, the second parallel clamp 52 can detect the change in force and stop working. Then the first parallel clamp 421 is started to drive the two first L rods 422 to approach each other. The first L rod 422 synchronously drives the arc plate 423 and the corresponding roller 424 on the arc plate 423 to approach each other to clamp the bottle cap of the plastic bottle. According to the pressure change of the first parallel clamp 421, it can be known whether the bottle cap is clamped. When the bottle cap is clamped After that, the stepper motor 432 is started, and the stepper motor 432 drives the disc 416 to rotate through the gear 433 and the ring gear 431. At this time, the rotation of the disc 416 will drive the bottle cap of the plastic bottle to rotate synchronously, firstly strengthening the connection between the bottle cap and the bottle body to achieve airtightness of the gas in the bottle, and then the second parallel clamping jaw 52 continues to start to squeeze the bottle body. At this time, the gas in the plastic bottle is compressed, and then the stepper motor 432 drives the gear 433 to quickly release the connection between the bottle cap and the bottle body. Under the action of the roller 424, the resistance of the bottle cap is greatly reduced. Under the release of the compressed gas in the plastic bottle, the bottle cap quickly detaches from the bottle body and flies away from the bottle body, and then the components of the blocking and picking mechanism 4 are reset, and the second micro servo motor 414 is started to drive the first rotating shaft 412 to rotate, and the clamping part 42 and the rotating part 43 are driven to rotate through the first rotating shaft 412, the connecting plate, the first fixing ring 415, and the disc 416 to release the blockage of the end of the through pipe 2 away from the input port 12.

[0066] The transmission part 61 includes a third servo motor 611 installed on one of the second through holes 24, a mounting seat 612 is provided on the second through hole 24 on the same side, a second rotating shaft 613 is installed on the mounting seat 612, a first sprocket 614 and a second sprocket 615 are both sleeved on the third servo motor 611 and the second rotating shaft 613, and a chain 616 is connected between the first sprocket 614 and the second sprocket 615.

[0067] The separation part 62 includes a square seat 622 installed between the two chains 616 through a fixing rod 621. There are several square seats 622. A third rotating shaft 623 is installed on each of the square seats 622. Both ends of the third rotating shaft 623 are sleeved with torsion springs 624. One end of the torsion spring 624 is connected to the third rotating shaft 623, and the other end is connected to the square seat 622. The third rotating shaft 623 is fixed with a barb knife 625. There are several barb knives 625. When the barb knife 625 is located outside the through pipe 2, its curved knife part faces the inside of the through pipe 2. When the barb knife 625 is located inside the through pipe 2, its curved knife part faces the outside of the through pipe 2. The separation part 62 also includes a support plate 626 arranged in the recycling machine body 1. A fan 627 is installed on the support plate 626. The fan 627 is located just above the first through hole 23. The arc frame 54 at the bottom is arranged at one end away from the input port 12 with a barb claw 628.

[0068] like Fig.10 , 11 As shown, the third servo motor 611 is started, and with the cooperation of the second rotating shaft 613, the chain 616 is driven to transmit through the first sprocket 614 and the second sprocket 615. The chain 616 drives the square seat 622 to move synchronously through the fixed rod 621. The barbed knife 625 on the square seat 622 is always in contact with the body of the plastic bottle under the action of the torsion spring 624. When it is necessary to drive the plastic bottle to move into the recycling machine body 1, the back of the barbed knife 625 presses the plastic bottle and drives the plastic bottle to move with the movement of the chain 616. When it is necessary to separate the label on the plastic bottle, as the bottle body clamping mechanism 5 clamps the plastic bottle, after the bottle cap is separated from the plastic bottle, the body of the plastic bottle is still in In the compressed state, the protruding sides of the plastic bottle are in closer contact with the barb knife 625, and the third servo motor 611 rotates in the opposite direction. At this time, the blade on the barb knife 625 will cut the two sides of the label. After the cutting is completed, the bottle body clamping mechanism 5 is reset, and then the fan 627 is started to discharge the cut label from the gap between the arc frame 54 below, completing the separation of the label and the bottle body. The barb claw 628 can prevent the cut part of the label located below the plastic bottle from being unable to be discharged due to the obstruction of the plastic bottle. When the subsequent plastic bottle continues to move, the part of the label is driven to leave the arc frame 54. After a single plastic bottle is discharged from the through pipe 2, the fan 627 can be turned on for the second time to ensure the complete recovery of a single label.

[0069] A compression mechanism 7 is installed in the recycling machine body 1, and the compression mechanism 7 flattens the separated plastic bottles. The compression mechanism 7 includes a support frame 71 arranged in the recycling machine body 1, and an electric roller 72 is relatively installed on the support frame 71. The electric roller 72 is located below the end of the through pipe 2 away from the input port 12.

[0070] As the transmission separation mechanism 6 applies a moving force to the plastic bottle, the plastic bottle slides from the end of the through tube 2 away from the input port 12 to the electric roller 72, and after being flattened by the electric roller 72, falls to the bottom of the recycling machine body 1, completing the recycling of the plastic bottle body.

[0071] A collecting mechanism 8 is installed in the recycling machine body 1. The collecting mechanism 8 collects the separated labels and bottle caps, including a guide plate 81 installed on the support frame 71. The guide plate 81 is half-trumpet-shaped and is located directly below the through pipe 2. The recycling machine body 1 is installed with a collecting basket 82. The collecting basket 82 is located directly below the end of the guide plate 81 away from the support frame 71. The collecting mechanism 8 also includes a second fixing ring 83 installed on the side of the support frame 71 away from the through pipe 2. The second fixing ring 83 is provided with an annular groove 84 on the side away from the support frame 71. A collecting bag 85 is clamped on the annular groove 84, and a docking ring 86 that matches the annular groove 84 is provided at the opening of the collecting bag 85.

[0072] like Figure 2 , 3 As shown in FIGS. 4 and 6, under the cooperation of the bottle body clamping mechanism 5 and the blocking and removing mechanism 4, the compressed gas in the plastic bottle is released, and the bottle cap quickly detaches from the bottle body and flies forward in a parabola, and the distance between the second fixing ring 83 and the first fixing ring 415 is small, which is 1.5-2 times the height of the bottle. The flight trajectory of the bottle cap changes slightly within this distance segment, and it can smoothly pass through the second fixing ring 83 and enter the collecting bag 85. The collecting bag 85 is preferably made of woven fabric, which can greatly reduce the impact force of the bottle cap, is low in cost, and is strong and durable. The design of the docking ring 86 and the annular groove 84 makes the collecting bag 85 more convenient to remove and install;

[0073] After the labels blown off by the fan 627 are separated from the arc frame 54 at the bottom, they fall into the collection basket 82 under the guidance of the guide plate 81, thereby completing the recovery of the labels.
