Description

Technical Field

[0001] The invention relates to the technical field of PET processing, in particular to a label removing machine for PET bottle flake processing. Background Art

[0002] Plastic bottles made of PET material are often bonded with labels related to the information of the items in the bottle. After the plastic bottles are crushed, their labels will be mixed in the bottle flakes, which is time-consuming and ineffective to remove, and is not conducive to the recycling of bottle flakes. The existing patent announcement number CN216760483U discloses a PET bottle flake label removal machine that shortens the time required for tool change. Although the device can assist in label removal by adding hot water, this label removal method requires an additional dehydration process, which is not conducive to improving efficiency. The patent announcement number CN219112384U discloses a suction label removal machine. Although the device can separate the label from the bottle flakes, the device lacks an automatic processing mechanism, which is not conducive to controlling the amount of feed. Too much feed will result in incomplete label removal of the bottle flakes, and too little feed will result in too low efficiency, which is not conducive to improving efficiency.

[0029] like Figure 1-Figure 3As shown, an embodiment of the present invention provides a label removal machine for PET bottle flakes processing, including a separation cylinder 100, wherein a feed port 101 for feeding is provided at the upper end of the separation cylinder 100, and an intermittent feeding component 400 for feeding is provided at the position of the feed port 101. Intermittent feeding is performed by the intermittent feeding component 400 to ensure that the feeding amount is fixed each time, and there is no need for staff to continuously feed the material. A separation roller is provided inside the separation cylinder 100, and a pushing blade 109 for pushing the material is distributed on the outer side of the separation roller. A plurality of separation blades 106 are provided on the surface of the separation roller downstream of the pushing blade 109, and a plurality of separation blocks 107 are distributed on the surface of the separation blade 106. The separation roller drives the peeling block 107 to rotate, thereby assisting the label to be detached. One end of the separation roller is connected to a driving shaft 111, and the driving shaft 111 is connected to a driving motor 108 for driving the rotation thereof. The driving motor 108 is fixedly connected to the separation cylinder 100 through a motor 104. A discharge port 105 for discharging is provided at the lower end of the separation cylinder 100, and a material receiving chute 103 for collecting materials is provided below the discharge port 105. The material receiving chute 103 is inclined, and a material raising component for raising bottle flakes is provided on the material receiving chute 103.

Under the action of the negative pressure fan 302, suction is generated above the material receiving slide 103, thereby sucking away the labels in the bottle flakes, and the sucked away labels will be sent to the collection mechanism; The collecting mechanism includes a filter cartridge 308 fixedly arranged at the end of the air outlet pipe 303, a plurality of filter holes are distributed in the filter area outside the filter cartridge 308, a rotating ring 309 is rotatably provided at the end of the filter cartridge 308, a plurality of power blades 304 are distributed on the outside of the rotating ring 309, the power blades 304 are distributed on the outside of the filter cartridge 308, the power blades 304 and the inclined surface of the filter cartridge 308 are arranged at an acute angle, a discharge port is provided at the end of the rotating ring 309, a movable door 306 is provided at the position of the discharge port, and the movable door 306 and the discharge port are threadedly connected A pull ring 307 is fixedly provided on the outer side of the movable door 306, and an anti-blocking scraper sheet 305 matching the inner wall of the filter cartridge 308 is provided on the inner side of the rotating ring 309. When the airflow is discharged along the filter hole of the filter cartridge 308, the power blades 304 will be subjected to the thrust of the airflow. The thrust generated by the multiple power blades 304 will form a rotational torque that drives the rotating ring 309 to rotate, thereby driving the rotating ring 309 to rotate. The anti-blocking scraper sheet 305 on the rotating ring 309 will scrape the inner wall of the filter cartridge 308 to avoid clogging caused by impurities. like Figure 1-Figure 6 As shown, the material lifting component includes a material lifting step 110 arranged on the material receiving slide 103, and the material lifting step 110 is located at the discharge port 105. After the bottle pieces fall, since the surface of the material lifting step 110 is a step structure, the bottle pieces will slide down in multiple waterfalls, which is helpful for lifting the material, so that the lightweight labels in the bottle pieces will be dispersed, which is convenient for negative pressure adsorption; The material lifting component also includes a stripping roller 207 rotatably arranged inside the material receiving slide 103, and a plurality of stripping scrapers 208 are distributed on the outer side of the stripping roller 207. The end of the stripping roller 207 is connected to the first pulley 201 through a connecting shaft. The end of the separation cylinder 100 is provided with a second bevel gear 206 connected to the end of the separation roller shaft. One side of the second bevel gear 206 is meshed with the first bevel gear 205. The first bevel gear 205 is connected to the center of the second pulley 203 through a transmission shaft. A bearing sleeve 204 rotatably connected to the transmission shaft is fixedly provided at the end of the separation cylinder 100. The second pulley 201 is connected to the first pulley 201 through a connecting shaft. 03 is connected to the first pulley 201 through the second pulley 203. When the driving shaft 111 drives the separation roller to rotate, the second bevel gear 206 will also rotate. The second bevel gear 206 drives the second pulley 203 to rotate through the first bevel gear 205. The second pulley 203 drives the first pulley 201 to rotate through the transmission belt 202. The first pulley 201 drives the stripping roller 207 to rotate, thereby providing power for the stripping roller 207 to rotate. When the stripping roller 207 rotates, it will move the bottle pieces sliding down the inclined surface of the material receiving slide 103 to avoid accumulation between the bottle pieces, which is conducive to negative pressure suction. like Figure 7-Figure 8As shown, the intermittent feeding component 400 includes a buffer hopper 401, a floating push plate 403 is slidably provided at the bottom opening position of the buffer hopper 401, a notch is provided on the upper end of the buffer hopper 401 near the feeding port 101, and a guide pipe 402 is provided at the notch position for guiding the bottle chips into the feeding port 101, and an inclined surface inclined toward the notch is provided at the upper end of the floating push plate 403, and a floating pushing mechanism is connected at the lower end of the floating push plate 403 for driving the floating push plate 403 to reciprocate up and down, and the floating pushing mechanism can drive the floating push plate 403 to reciprocate up and down, and when the floating push plate 403 moves to the lowest side, the upper end of the floating push plate 403 will be submerged by the bottle chips, and as the floating push plate 403 moves upward, a lot of bottle chips will gather between the upper inclined surface of the floating push plate 403 and the buffer hopper 401, and when the floating push plate 403 moves upward, the bottle chips will be pushed and finally discharged along the guide pipe 402; like Figure 7 As shown, the floating pushing mechanism includes a mounting sleeve 406 fixedly sleeved on the outside of the driving shaft 111, a driving ring frame 412 is provided on the outside of the mounting sleeve 406, the driving ring frame 412 and the mounting sleeve 406 are connected by a plurality of reinforcing rods 405, an elliptical transmission groove 407 is provided on the surface of the driving ring frame 412, a floating push rod 404 is provided at the middle position of the lower end of the floating push plate 403, and a floating pin shaft 411 extending into the elliptical transmission groove 407 is provided on the side of the floating push rod 404. When the driving ring frame 412 rotates, the floating push rod 404 is provided with a floating pin shaft 411 extending into the elliptical transmission groove 407. The pin shaft 411 will slide along the inside of the elliptical transmission groove 407. Since the elliptical transmission groove 407 is an elliptical structure, as the driving ring frame 412 rotates, the floating pin shaft 411 will change along the trajectory of the elliptical transmission groove 407, thereby driving the floating push rod 404 and the floating push plate 403 to change in height, thereby providing a floating thrust. When the floating pin shaft 411 contacts the long diameter position of the elliptical transmission groove 407, the floating push plate 403 is at the highest position, and when the floating pin shaft 411 contacts the short diameter position of the elliptical transmission groove 407, the floating push plate 403 is at the lowest position; The floating push plate 403 is provided with a guide mechanism on both sides. The guide mechanism includes a guide side groove 408 provided on both sides of the floating push plate 403. A guide side block 410 is slidably provided in the guide side groove 408. The outer end of the guide side block 410 is connected to the separation cylinder 100 through a guide side rod 409. Under the guidance of the guide side groove 408 and the guide side block 410, the floating push plate 403 is lifted and lowered more smoothly: like Figure 1-Figure 3As shown, the material receiving slide 103 is provided with a scattering component for auxiliary scraping of bottle pieces, and the scattering component includes at least one transverse material flipping plate 502, the cross-section of the transverse material flipping plate 502 is triangular, and the transverse material flipping plate 502 is slidably matched with the surface of the material receiving slide 103, and the end of the transverse material flipping plate 502 is connected to the connecting cross bar 503 through a connecting rod, and the connecting cross bar 503 is connected to the lower end of the transverse frame 501 through the connecting cross bar 503, and a transverse guide sleeve 505 is provided at the upper end of the transverse frame 501, and a transverse guide rod 504 is slidably provided in the transverse guide sleeve 505, and the transverse guide rod 504 is slidably provided with the transverse guide rod 504. The end of the separation cylinder 100 is connected and fixed by a positioning block, and a transverse shifting pin 506 is provided at the upper end of the transverse frame 501, and the end of the transverse shifting pin 506 matches the elliptical transmission groove 407 in the driving ring frame 412. When the driving ring frame 412 rotates, as the trajectory of the elliptical transmission groove 407 changes, the transverse shifting pin 506 will guide the transverse frame 501 to move horizontally, and the transverse frame 501 will slide horizontally along the transverse guide sleeve 505 and the transverse guide rod 504, and the transverse flipping plate 502 connected to the lower end of the transverse frame 501 will reciprocate on the unloading surface of the receiving slide 103, so as to further break up the bottle pieces in the sliding process; The ends of the transverse shifting pin 506 and the floating pin shaft 411 are both rotatably provided with drive sleeves, which helps to reduce wear.

[0030] Working principle: In actual use, bottle flakes are first added into the buffer hopper 401, and the driving motor 108 drives the driving shaft 111 to rotate, and the driving shaft 111 drives the driving ring frame 412 and the separation roller to rotate. When the driving ring frame 412 rotates, the floating pin shaft 411 will slide along the inside of the elliptical transmission groove 407. Since the elliptical transmission groove 407 is an elliptical structure, as the driving ring frame 412 rotates, the floating pin shaft 411 will change along the trajectory of the elliptical transmission groove 407, thereby driving the floating push rod 404 and the floating push plate 403 to change in height. When the floating push plate 403 moves to the lowermost side, the upper end of the floating push plate 403 will be submerged by the bottle flakes. As the floating push plate 403 moves upward, many bottle flakes will gather between the upper end inclined surface of the floating push plate 403 and the buffer hopper 401. When the floating push plate 403 moves upward, the bottle flakes will be pushed and finally discharged along the guide pipe 402.

[0031] The discharged guide pipe 402 will enter the separation cylinder 100 along the feed port 101. When the separation roller rotates, the separation blades 106 on the surface of the separation roller will stir the bottle flakes, so that the labels and bottle flakes are separated. The pre-treated bottle flakes are discharged along the discharge port 105 and then passed through the receiving chute 103. Since the surface of the lifting step 110 is a stepped structure, the bottle flakes will slide down in multiple waterfalls, which is helpful for lifting the material. In this way, the light labels in the bottle flakes will be dispersed, which is convenient for negative pressure adsorption. When the driving shaft 111 drives the separation roller to rotate, the second bevel gear 206 will also rotate, and the second bevel gear 206 drives the second pulley 203 to rotate through the first bevel gear 205, and the second pulley 203 drives the first pulley 201 to rotate through the transmission belt 202, and the first pulley 201 drives the stripping roller 207 to rotate, thereby providing power for the stripping roller 207 to rotate. When the stripping roller 207 rotates, it will move the bottle pieces sliding down the inclined surface of the material receiving slide 103 to avoid accumulation between the bottle pieces, which is conducive to negative pressure suction; When the driving ring frame 412 rotates, along with the change of the trajectory of the elliptical transmission groove 407, the transverse shifting pin 506 will guide the transverse frame 501 to move horizontally, and the transverse frame 501 will slide horizontally along the transverse guide sleeve 505 and the transverse guide rod 504, and the transverse material turning plate 502 connected to the lower end of the transverse frame 501 will reciprocate on the unloading surface of the receiving slide 103, so as to further break up the bottle pieces in the sliding process; When the broken bottle pieces slide down, under the action of the negative pressure fan 302, suction will be generated above the receiving slideway 103, so that the labels in the bottle pieces are sucked away, and the sucked away labels will be sent to the collection mechanism.

[0032] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
