[0029] The embodiments of the present utility model are described in detail below with reference to the accompanying drawings.

[0030] Embodiment 1:

[0031] like Figure 1-4 As shown, a device for removing labels from discarded plastic bottles includes a supporting platform 1 and a gantry 2 fixedly connected to the top of the supporting platform 1 by bolts.

[0032] An electric push rod 3 is fixed to the upper surface of the top of the gantry 2 by bolts, and the telescopic end of the electric push rod 3 is fixedly connected to a driving mechanism 5 through a connecting frame 4. The bottom transmission of the driving mechanism 5 is matched with a label removal plate 6 and a label removal barrel 7. A leakage hole is opened at the bottom of the label removal barrel 7, and a soaking pool 8 is placed on the top outer wall of the supporting platform 1 located at the bottom of the label removal barrel 7. The side wall of the soaking pool 8 is fixedly connected to a heat pump 25 through a connecting pipe 1, and the other end of the heat pump 25 is fixedly connected to a liquid storage tank 24 through a connecting pipe 2.

[0033] First, drive the labeling plate 6 to rise so that the top of the labeling barrel 7 is opened, and then the crushed plastic bottles are put into the labeling barrel 7, and the electric push rod 3 is started to drive the labeling plate 6 and the labeling barrel 7 to descend into the soaking pool 8 together, and then drive the labeling plate 6 to descend to contact with the plastic bottle fragments and maintain a certain pressure, and then start the heat pump 25 to extract the liquid in the liquid storage tank 24, and send it to the soaking pool 8 after heating, so that the plastic bottle fragments are completely soaked, and then use the driving mechanism 5 to synchronously drive the labeling plate 6 and the labeling barrel 7 to rotate in different directions, so that the labeling plate 6 and the labeling barrel 7 are used to "knead" the plastic bottle fragments to remove the paper labels adhered to the plastic bottle fragments, and at the same time, the paper labels will also be "kneaded" and crushed, suspended in the liquid to achieve separation.

[0034] The device realizes the "kneading" function of the bottle fragments by setting a label removing plate 6 and a label removing barrel 7, and utilizes the different direction rotation of the label removing plate 6 and the label removing barrel 7, and exerts a certain squeezing force on the fragments, so as to realize the complete separation of the paper label by using pressure and "kneading", and the separated paper label will be suspended in the liquid, so as to realize the "filtration" of the label and the plastic bottle fragments.

[0035] In this embodiment, the driving mechanism 5 includes a gear 19, a gear ring 10, a lifting shaft 14 and a shell 17. The shell 17 is fixedly connected to the bottom of the connecting frame 4. The gear 19 is rotatably connected to the shell 17 through a hollow cylinder 26, and the gear ring 10 is rotatably connected to the inner wall of the shell 17. A plurality of gears 19 are meshed on the opposite side of the gear 19 and the gear ring 10. The gear 19 is fixedly connected to the top of the shell 17 through a rotating shaft 18.

[0036] The inner wall of the gear 1 9 can only be connected to the lifting shaft 14 in a longitudinal sliding manner, one end of the lifting shaft 14 is fixedly connected to the label removal barrel 7, and the outer wall of the other end of the lifting shaft 14 can only be connected to the shaft sleeve 15 in a longitudinal sliding manner, and the outer wall of the shaft sleeve 15 is fixedly connected to the gear three 16.

[0037] The motor 11 is fixed to the lower surface of the top of the housing 17 by bolts, and the output shaft of the motor 11 is fixedly connected to the driving shaft 13 through a coupling. The outer wall of the driving shaft 13 is welded with a gear 2 12, and the gear 2 12 and the gear 3 16 are meshed with each other.

[0038] The gear 1 9 and the inner wall of the sleeve 15 are fixedly connected with a flat key 21, and the outer wall of the lifting shaft 14 is provided with a key groove 22 which is limitedly matched with the flat key 21.

[0039] After the plastic bottle fragments are put into the label removal barrel 7, the electric push rod 3 is started to drive the connecting frame 4 to drive the shell 17 to descend, and the shell 17 uses the lifting shaft 14 to drive the label removal plate 6 and the label removal barrel 7 to descend at the same time. When the label removal barrel 7 contacts with the immersion pool 8, the label removal barrel 7 is restricted by the immersion pool 8 and no longer moves. At this time, the electric push rod 3 continues to push the connecting frame 4, and the flat key 21 and the key slot 22 are used to cooperate to make the label removal plate 6 continue to descend until the label removal plate 6 contacts with the plastic bottle fragments and maintains a certain pressure. Then the electric push rod 3 is closed, and then the heat pump 25 is used to transport the heated liquid into the immersion pool 8. The liquid The liquid enters the label stripping barrel 7 through the leakage hole at the bottom of the label stripping barrel 7, and then the motor 11 is started to drive the gear 2 12 and the driving shaft 13 to rotate, and the driving shaft 13 drives the gear 3 16 and the shaft sleeve 15 to rotate. Under the limit cooperation of the flat key 21 and the keyway 22, the lifting shaft 14 drives the gear 1 9 and the label stripping barrel 7 to rotate, and the gear 1 9 uses the gear 4 19 to drive the gear ring 10, the connecting rod 20 and the label stripping plate 6 to rotate. Due to the cooperation of the gear 1 9, the gear ring 10 and the gear 4 19, the label stripping plate 6 and the label stripping barrel 7 rotate synchronously but in different directions, thereby realizing the "rubbing" of the plastic bottle fragments.

[0040] The device is provided with gear 1 9, gear ring 10 and gear 4 19, which cooperate with each other to realize simultaneous but different-direction rotation of the label stripping plate 6 and the label stripping barrel 7, thereby increasing the relative rotation speed of the label stripping plate 6 and the label stripping barrel 7 and improving the label stripping efficiency.

[0041] In this embodiment: first, the crushed plastic bottle fragments are put into the label removal barrel 7, and then the electric push rod 3 is started to drive the connecting frame 4 to drive the shell 17 to descend. The shell 17 uses the lifting shaft 14 to drive the label removal plate 6 and the label removal barrel 7 to descend together. When the label removal barrel 7 contacts the immersion pool 8, it is blocked by the immersion pool 8 and no longer moves. At this time, the electric push rod 3 continues to push the connecting frame 4. Due to the cooperation of the flat key 21 and the key slot 22, the shell 17 continues to drive the label removal plate 6 to descend until the label removal plate 6 contacts the plastic bottle fragments and maintains a certain pressure. Then the heat pump 25 is started to extract and heat the liquid in the liquid storage tank 24, and then transport it to the immersion pool 8. The liquid passes through the label removal barrel The liquid leakage hole at the bottom of 7 enters into the label stripping barrel 7, so that the plastic bottle fragments are completely immersed, and then the motor 11 is started to drive the gear two 12 and the driving shaft 13 to rotate, and the driving shaft 13 drives the gear three 16 and the shaft sleeve 15 to rotate, so that the lifting shaft 14 drives the gear one 9 and the label stripping barrel 7 to rotate by utilizing the limit cooperation of the flat key 21 and the keyway 22, and the gear ring 10 drives the label stripping plate 6 to rotate in the opposite direction by utilizing the connecting rod 20 under the cooperation of the gear four 19 and the gear one 9, so as to realize the "rubbing" function of the plastic bottle fragments, and remove the paper labels adhered to the plastic bottle fragments, and at the same time, the paper labels will also be "rubbed" and crushed, suspended in the liquid, to achieve separation.
