Description

Technical Field

[0001] The invention relates to the technical field of PET plastic recycling and reuse, in particular to a PET plastic bottle recycling granulator. Background Art

[0002] Plastic bottles are disposable plastic packaging containers mainly used for liquids or solids such as beverages, foods, pickles, honey, dried fruits, cooking oils, pesticides and veterinary drugs. Plastic bottles widely use polyester (PET), polyethylene (PE), and polypropylene (PP) as raw materials. The bottle body is made of polyester (PET) material, and the bottle cap is made of polyethylene (PE) or polypropylene (PP) material; the traditional way of disposing of waste plastic bottles is landfill and incineration. These two treatment methods will greatly pollute the land and the atmosphere. Therefore, there is a way to recycle and reuse waste plastic bottles (a form of comprehensive utilization of solid waste). Recycling granulators are used to recycle and reprocess waste plastic bottles to solve pollution problems and create production value.

[0003] The existing plastic bottle recycling and granulating machines have many technical defects when in use. First, when collecting plastic bottle labels, a fixed fan is generally installed. The fixed fan has a small suction range and there are dead corners when sucking materials, which leads to unclean cleaning of labels in the label tearing machine, easy blockage, and high energy consumption; second, when using a crusher to cut and crush plastic bottles, the fragments generated are inconsistent in size, and some large fragments cannot be directly granulated. They are directly discarded after being sieved by the screen, resulting in a waste of resources; third, the fragments of bottle cap plastic will float to the surface of the water washing pool, and need to be manually salvaged and cleaned in time to avoid blockage, but manual cleaning is time-consuming and labor-intensive, and the degree of automation is low.

[0032] The present invention provides a PET plastic bottle recycling granulator through improvement, which has the following significant improvements and advantages compared with the prior art:

[0033] During the movement of the plastic bottle in the inner cavity of the spiral label tearer, one side of the plastic bottle contacts the circular scribing piece, which randomly scratches the plastic bottle label, causing the plastic bottle label to be cut by a sharp object. On the other side, the plastic bottle randomly contacts the pushing piece of the feeder in the inner cavity of the spiral label tearer. The pushing piece and the plastic bottle label interact with each other, and the shaft sleeve drives the pushing piece to rotate slightly after being subjected to force. The plastic bottle label falls off after being subjected to the thrust. The two work together to significantly improve the effect and efficiency of automatic label removal.

[0034] The uniform speed motor is started, and after being decelerated by the reducer, it drives the positioning shaft to rotate, causing the chain to move in a circle, and drives several groups of movable label suckers on the chain to move in a circle. When the movable label sucker moves with the chain in the lower half of the protective cover, the material suction short tube of the movable label sucker passes through the strip guide groove, moves inside the spiral label tearer, and keeps synchronization with the movement of the plastic bottle. The material suction fan of the movable label sucker is started, and the label that falls off in the spiral label tearer is sucked in time by the material suction short tube, and discharged through the guide port. Tracking material suction improves the material suction effect, expands the material suction range, and solves the problem of dead angles in material suction.

[0035] Start the first servo motor to drive the camshaft to rotate at a low speed, causing the two groups of cams on the camshaft to make circular motion. The protruding part of the cam contacts the pulley on the self-vibrating screener during the motion, exerting a squeezing force on the pulley, and transmitting the force to the spring steel sheet of the self-vibrating screener, causing the bent part of the spring steel sheet to deform. When the protruding part leaves the pulley, the spring steel sheet will reset, causing the entire self-vibrating screener to move back and forth along the slide slot, causing the screen to vibrate, accelerating the movement of fine objects, achieving the purpose of screening and moving at the same time, solving the technical problem of low screening efficiency, and preventing the screen from being blocked.

[0036] Start the suction fan and use the long suction tube to suck up the fine flakes in the collection seat. The fine flakes move downward along the inclined guide tube and enter the storage barrel for temporary storage. Start the second servo motor on the quantitative feeder, and drive the entire transport wheel to do circular motion through a series of transmission positioning shafts, so that one group of quantitative slots moves to the feed part position. The fine flakes in the storage barrel will be transferred from the feed part to the quantitative slot, achieving the quantitative feeding effect, which is more suitable for the crushing efficiency. The quantitative slot moves with the transport wheel to the discharge area of ​​the outer wheel shell, and the fine flakes in the quantitative slot are discharged into the discharge part and re-enter the crushing chamber for cutting again, forming multi-stage crushing to avoid the waste of fine flake resources.

[0037] The third servo motor is turned on, and after a series of transmissions, the flip roller rotates, and the extension arm drives the perforated scoop frame to extend downward below the water surface of the sorting tank. Then the third servo motor works in the opposite direction, and after transmission, the extension arm drives the perforated scoop frame to move upward. When the perforated scoop frame passes through the water surface, it scoops up several floating thin pieces until the collision groove of the perforated scoop frame contacts the spring column, generating an impact force, causing the connecting steel sheet to shake, so that the perforated scoop frame vibrates, and the thin pieces in the frame are poured into the waste collection seat, thereby achieving the effect of automatic salvage, saving time and effort, and with vibration dumping, avoiding residue inside the perforated scoop frame.

DETAILED DESCRIPTION

[0056] 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. Embodiment 1

[0057] like Figure 1-14 As shown, this embodiment provides a PET plastic bottle recycling granulator, including a base 1, which plays a bearing and supporting role. The upper end of the base 1 is connected to a label tearing box 3 through two groups of connecting arms 2, and the connecting arms 2 play a supporting role. A spiral label tearing device 10 is arranged inside the label tearing box 3.

[0058] The upper end surface of the label tearing box 3 is provided with a feeding port 11 at the right position downward through the spiral label tearing device 10, and a spiral driving motor 12 is installed at the end of the spiral label tearing device 10.

The inner wall of the spiral label tearing device 10 is evenly distributed with a feeder 16 for acting on the labels of the plastic bottles. Figure 4 shown.

[0060] Specifically, the material dispensing device 16 includes a positioning shaft 161, a shaft sleeve 162, an inner rotation groove 163, an arc groove 164, a spring pressure block 165, a compression spring 166 and a push piece 167, as shown in FIG. Figure 5-Figure 6 shown.

[0061] In this embodiment, the positioning shaft 161 is fixed on the inner wall of the spiral label tearing device 10, and a sleeve 162 is movably provided on the upper end of the positioning shaft 161. The sleeve 162 rotates around the positioning shaft 161 to prevent the push piece 167 from being stuck when it contacts the plastic bottle label. An inner rotation groove 163 for the positioning shaft 161 to extend into is opened downward inside the sleeve 162, and two groups of arc grooves 164 are symmetrically opened at the outer end of the inner rotation groove 163.

[0083] Furthermore, a drain valve is installed at the lower left end of the water washing tank 5 for discharging sewage in the sorting tank 6 .

[0084] When the present embodiment is in use, recycled plastic bottles are intermittently put into the spiral label tearing device 10 from the feeding port 11, and then the spiral driving motor 12 is operated, the roller 13 drives the spiral blade 14 to rotate, so that several groups of spiral blades 14 drive the plastic bottles to move from right to left. During the movement of the plastic bottle in the inner cavity of the spiral label tearing device 10, one side of the plastic bottle contacts the circular scribing piece 15, and the scribing piece 15 randomly scratches on the plastic bottle label, so that the plastic bottle label is scratched by a sharp object, and the other side of the plastic bottle randomly contacts the pushing piece 167 of the material picker 16 in the inner cavity of the spiral label tearing device 10. The pushing piece 167 and the plastic bottle label interact with each other, and the shaft sleeve 162 drives the pushing piece 167 to rotate slightly after being subjected to force, and the plastic bottle label falls off after being subjected to the thrust, and several groups of material pickers 16 contact in sequence, so that the label is slowly separated from the plastic bottle, until the plastic bottle moves to the discharge port area of ​​the spiral label tearing device 10, and the label is completely removed.

[0085] During the process of label removal, the uniform speed motor 91 is started synchronously, and after being decelerated by the reducer 90, the positioning shaft 161 is driven to rotate, so that the two groups of sprockets 23 rotate synchronously clockwise, causing the chain 24 to move in a circular manner, and driving several groups of movable label suckers 25 on the chain 24 to make circular movements. When the movable label suckers 25 move with the chain 24 in the lower half of the protective cover 20, the material suction short tube 254 of the movable label sucker 25 passes through the strip guide groove 17 and moves inside the spiral label tearing device 10 (synchronized with the movement of the plastic bottle), and the material suction fan 253 of the group of movable label suckers 25 is started, and the labels that fall off in the spiral label tearing device 10 are sucked in time by the material suction short tube 254, and discharged through the guide port 255, and transferred to the label collection box 26 for centralized collection.

[0086] The plastic bottles discharged from the discharge port go downward into the discharge seat 30, and are transferred to the crushing chamber 32 through the discharge seat 30, and are discharged at an angle on the curved aggregate surface 34. At this time, the crushing knife group 33 is put into operation, and several groups of crushing blades rotate at high speed to fully cut the plastic bottles on the curved aggregate surface 34, so that they are turned into fine flakes (including bottle body plastic and bottle cap plastic). The fine flakes will fall downward on the curved aggregate surface 34, and fall from the middle material port 35, and fall onto the screen 43 of the self-vibrating screener 4. The fine flakes that meet the specifications will pass through the screen 43 and fall downward into the sorting trough 6 of the washing tank 5, and the fine flakes that do not meet the specifications will move downward along the screen 43 and finally enter the collecting seat 36 to be collected.

[0087] At the same time, the first servo motor 53 is started, driving the camshaft 51 to rotate at a low speed, causing the two groups of cams 50 on the camshaft 51 to make circular motion. The protruding part of the cam 50 contacts the pulley 46 on the self-vibrating screener 4 during the movement, generating an extrusion force on the pulley 46, causing the bracket frame 41 to move obliquely downward, and transmitting the force to the spring steel sheet 44 of the self-vibrating screener 4, causing the bent part of the spring steel sheet 44 to deform. Because the spring steel sheet 44 has deformation reset property, the spring steel sheet 44 will be reset when the protruding part leaves the pulley 46, and the bracket frame 41 will move obliquely upward, thereby causing the entire self-vibrating screener 4 to move back and forth along the slide 93, causing the screen 43 to vibrate, accelerating the movement of fine pieces, and achieving the purpose of screening while moving.

[0088] The suction fan 61 is started regularly, and the thin pieces in the collecting seat 36 are sucked up by the long suction tube 62 and transferred to the inclined guide tube 63. The thin pieces move downward along the inclined guide tube 63 and enter the storage barrel 64 for temporary storage. The second servo motor 659 on the quantitative feeder 65 is started to drive the first small gear 658 to rotate, and the first large gear 657 is decelerated by meshing. The rotating shaft 655 drives the entire conveying wheel 653 to make a circular motion, so that one group of quantitative slots 654 moves. The conveyor wheel 653 moves to the position of the feed section 651 to form a docking. At this time, the fine flakes in the storage barrel 64 will be transferred from the feed section 651 to the quantitative groove 654. The quantitative groove 654 moves with the transport wheel 653 to the discharge section 652 area of ​​the outer wheel shell 650 and stops moving. The fine flakes in the quantitative groove 654 are discharged into the discharge section 652 and enter the discharge seat 30. The fine flakes transition through the discharge seat 30 and re-enter the crushing chamber 32 for further cutting until they meet the screening specifications.

[0089] The flakes entering the sorting water tank 6 will be cleaned, and at the same time, the flakes of bottle cap plastic will float to the water surface (lower density than water), and the flakes of bottle body plastic will settle to the bottom of the water (sealing is greater than water), and enter the first screw conveyor 7 with an open bottom. The first screw conveyor 7 transports the flakes of bottle body plastic from left to right and enters the second screw conveyor 8. The second screw conveyor 8 is then used to transport the flakes obliquely upward (open the faucet during transportation to rinse the adsorbed impurities on the surface of the flakes), transfer them out of the washing tank 5, and fall from the bottom of the second screw conveyor 8 into the hopper 92, continuously supplying the granulator 9, which mixes and extrudes the flakes into granules, thereby achieving the purpose of recycling plastics and realizing the comprehensive utilization of fixed waste. Embodiment 2

[0090] On the basis of the first embodiment, the thin pieces of bottle cap plastic will float to the water surface of the washing tank 5, and they need to be salvaged and cleaned manually in time to avoid blockage, but manual cleaning is time-consuming and laborious, and the degree of automation is low. In order to solve the above technical problems, we have the following design, such as Figure 15-17 shown.

[0091] Specifically, two groups of positioning seats 70 are symmetrically riveted at the left end of the washing tank 5, and a turning roller 71 is rotatably arranged between the two groups of positioning seats 70. The two ends of the turning roller 71 are fixed inside the positioning seat 70 through a third bearing seat 72. Fig.15 and Fig.17 shown.

[0092] Among them, one end of the flip roller 71 extends outwardly and is sleeved with a second large gear 73, and the upper end of the second large gear 73 is meshed with a second small gear 74, and the second small gear 74 is sleeved on the output shaft of the third servo motor 75, and the third servo motor 75 is horizontally arranged through the outer side surface of the positioning seat 70, such as Fig.16 and Fig.17 shown.

[0093] The middle part of the turning roller 71 is sleeved with a connecting sleeve 80, and an extension arm 81 is welded on the outer side of the connecting sleeve 80. The extension arm 81 includes two groups of connecting steel sheets 82. The connecting steel sheets 82 are easily deformed after being compressed. A perforated scoop frame 83 is welded on the end of the extension arm 81 away from the connecting sleeve 80. A plurality of water seepage holes are opened at the bottom of the perforated scoop frame 83. The perforated scoop frame 83 extends downward to the water surface of the sorting tank 6. A collision groove 86 is opened on the right side of the upper end surface of the perforated scoop frame 83. Fig.16 and Fig.17 shown.

[0094] Further, the left ends of the two sets of positioning seats 70 are connected with a U-shaped slash bar 84, and the middle part of the U-shaped slash bar 84 is installed with a spring column 85 acting on the collision groove 86, and the spring column 85 includes a sheath, a spring and a column head. Fig.15 and Fig.16 shown.

[0095] Furthermore, a waste collection seat 94 is provided on the left side of the upper end surface of the base 1, and the waste collection seat 94 is located directly below the U-shaped slash bar 84. Fig.15 shown.

[0096] Furthermore, water is introduced from the right side of the sorting tank 6 by using a faucet, so that a water flow from right to left is formed in the tank, so that a number of floating fine pieces move to the left and are collected and salvaged.

[0097] When the present embodiment is in use, when cleaning the thin pieces of plastic from the bottle caps, the third servo motor 75 is turned on to drive the second small gear 74, and the second large gear 73 is decelerated by meshing, so that the turning roller 71 rotates, and the extension arm 81 drives the perforated scoop frame 83 to extend downward below the water surface of the sorting tank 6, and then the third servo motor 75 works in the reverse direction, causing the extension arm 81 to drive the perforated scoop frame 83 to move upward through transmission. When the perforated scoop frame 83 passes through the water surface, it scoops up a number of floating thin pieces, and continues to turn over with the extension arm 81 until the collision groove 86 of the perforated scoop frame 83 contacts the spring column 85 (the column head of the spring column 85 is compressed downward), generating an impact force, causing the connecting steel sheet 82 to shake, causing the perforated scoop frame 83 to vibrate, and pouring the thin pieces in the frame into the waste collection seat 94 (at this time, the scooping surface of the perforated scoop frame 83 faces downward), and the work is circulated like this.
