Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of plastic recycling, in particular to a label removing and cleaning device for recycling waste plastic bottles. BACKGROUND

[0002] In the recycling process of waste plastic bottles, the label usually needs to be removed because the material of the plastic bottle body is different from that of the label (for example, PET bottle body + PVC label), and mixed melting will form "impurity points" in the regenerated material, resulting in a decrease in the strength, transparency, weather resistance and other properties of the regenerated material. For example, if PET regenerated material is mixed with PVC labels, the regenerated bottle pieces made therefrom may have color difference and brittleness, and cannot be used for food-grade packaging (such as beverage bottles), but can only be used for plastic baskets, chemical fibers and other low-value products.

[0003] Generally, a label removing device is used to separate the bottle body from the label. The label removing device generally transports the PET bottle to the discharge end through the movement of alloy blades and spiral lines on the main shaft, and the alloy blades on the blades peel off the label. The blades also clean the bottle body while transporting and peeling off the label, ensuring the cleanliness of the bottle body and facilitating subsequent processing. Some dirt such as soil may be attached to the bottle body during recycling. This part of dirt will be separated from the bottle body during cleaning of the bottle body. Generally, a collecting and filtering device is provided at the bottom of the device. The peeled-off label, cleaning sewage and dirt such as sand will fall into the collecting and filtering device. The collecting device is provided with two layers. The first layer retains the label and other impurities through a filter plate, and the sand and sewage flow into the next layer to achieve layered collection.

[0052] A spraying device 7 is installed outside the cylinder 2 and is used to spray water into the cylinder 2;

[0053] A discharging bin 10 is installed at the bottom of the cylinder 2 and is connected to the inside of the cylinder 2;

[0054] A screening cylinder 11 is arranged below the cylinder 2 and is connected to the discharging bin 10;

[0057] Brush plates 15 are movably arranged inside the cylinder 12, the bottoms of the brush plates 15 are slidably attached to the surface of the filter plate 14, and the number of the brush plates 15 is two;

[0058] A telescopic assembly 9 is arranged inside the cylinder 12 and can drive the two brush plates 15 to move in opposite directions.

[0059] Specifically, a large number of waste plastic bottles are added into the inside of the barrel 2 through the feeding bin 3, the spraying device 7 is turned on to spray the cleaning agent and water into the barrel 2, the motor of the rotating shaft 5 is started, the rotating shaft 5 rotates to drive the plurality of blades 6 to rotate spirally, the blades 6 are in S shape, which can effectively avoid damaging the bottle body when the blades 6 peel off the label, the blades 6 rotate to peel off the label and move the plastic bottles in the barrel 2, the plastic bottles with peeled labels and cleaned are discharged through the discharging bin 4 at the other end of the barrel 2, in addition, a leakage hole smaller than the plastic bottle is arranged at the connection between the barrel 2 and the feeding bin 10, the peeled labels, cleaning wastewater and impurities such as silt fall into the feeding bin 10 and then into the screening cylinder 11, the screening cylinder 11 is composed of two layers of cylinders 12, the bottom of each layer of cylinder 12 is movably provided with a filter plate 14, a plurality of filter holes 141 are arranged in the filter plate 14, when the peeled labels, cleaning wastewater and impurities such as silt fall on the first layer of filter plate 14, the wastewater and small particle impurities fall on the next layer of filter plate 14 through the filter holes 141 of the layer, the labels are blocked on the surface of the first layer of filter plate 14, the filter plate 14 can be integrated with a shaking motor, which can shake synchronously during rotation, the labels on the surface of the filter plate 14 can be "flung" to the edge of the filter plate 14 by centrifugal force during rotation, which is convenient for discharging through the discharging bin 13, the shaking of the filter plate 14 can avoid the labels with water from being attached more closely to the surface of the filter plate 14, and is also beneficial to the impurities such as silt not staying on the first layer of filter plate 14, but part of the impurities such as silt can block the filter holes 141 of the filter plate 14, which affects the filtering effect, therefore, the brush plate 15 is moved along the surface of the filter plate 14 by the telescopic assembly 9, and the filter holes 141 are cleaned by the bristles at the bottom, which can effectively solve the problem of blockage of the filter holes 141, and the frame 1 provides support.

[0060] Referring to Figures 6-10 In the embodiment, the telescopic assembly 9 includes a fixed rod 91 fixedly installed in the inside of the cylinder 12, a moving frame 92 movably installed outside the fixed rod 91, a horizontal plate 93 fixedly installed at the bottom of the moving frame 92, horizontal grooves 94 axially and symmetrically arranged at both ends of the horizontal plate 93, a limiting frame 95 slidably arranged in the horizontal grooves 94, and a slot 96 arranged at the bottom of the limiting frame 95.

[0061] Specifically, when the moving frame 92 is located at one end of the fixed rod 91, there is an overlap at the middle part of the two brush plates 15 at this position, because this position is located at the edge of the filter plate 14, and the diameter is small, when it is necessary to clean the filter holes 141, the motor of the moving frame 92 is started, and the moving frame 92 moves transversely along the fixed rod 91, so that the transverse plate 93, the limiting frame 95 and the brush plate 15 move synchronously, and move from the edge of the filter plate 14 to the middle part of the filter plate 14, and the diameter of the filter plate 14 becomes larger and larger, at this time, the limiting frames 95 at both ends move transversely in the opposite direction along the transverse groove 94, and the sliding of the limiting frames 95 along the surface of the transverse plate 93 drives the notches 96 and the brush plates 15 to move synchronously, and the brush plates 15 on both sides move away from each other, so that more filter holes 141 can be cleaned, when the brush plates 15 move to the middle part of the filter plate 14, at this time, the brush plates 15 at both ends are farthest away from each other, and the coverage of the brush plates 15 is the largest, and the moving frame 92 continues to move in the same direction, and the diameter of the filter plate 14 gradually decreases, at this time, the limiting frames 95 move towards each other, which drives the two brush plates 15 to move towards each other, in this step, the telescopic assembly 9 can adjust the position of the brush plate 15 according to the change of the diameter of the filter plate 14, so that the filter plate 14 can be cleaned sufficiently, and the filter holes 141 can be prevented from being blocked.

[0062] As shown in Figure 8 and Figure 9 , in this embodiment, a plurality of pressing rods 16 are arranged in a transverse linear array at the top of the brush plate 15, the pressing rods 16 at one end away from the brush plate 15 are movably penetrated through the bottom of the limiting frame 95 and are connected together at the end through the connecting plate 17, the outer side of the pressing rod 16 movably sleeves the spring 18, and the two ends of the spring 18 are fixedly connected with the top of the brush plate 15 and the inner wall of the notch 96.

[0063] Specifically, when the brush plate 15 moves transversely back and forth along the transverse plate 93 under the action of the limiting frame 95, the connecting plate 17 is pressed downward, and the downward movement of the connecting plate 17 drives the pressing rod 16 to move downward, so that the brush plate 15 moves downward along the notch 96, and the bristle part of the brush plate 15 can penetrate into the inside of the filter hole 141, so that the filter hole 141 can be cleaned more thoroughly, and in this process, the spring 18 is stretched, and then the downward force applied to the connecting plate 17 is removed, and under the action of the spring 18, the connecting plate 17, the pressing rod 16 and the brush plate 15 move upward to the initial position, and then the above operation is repeated, so that the brush plate 15 can move up and down reciprocatingly, and the filter hole 141 can be cleaned deeply.

[0064] As shown in Figure 8 and Figure 9 , in this embodiment, the limiting rod 19 is fixedly arranged at the top of the connecting plate 17, the wave plate 20 is fixedly installed at the bottom of the transverse plate 93 in an axial symmetry, and the top of the limiting rod 19 is in sliding fit with the surface of the wave plate 20.

[0065] Specifically, when the limiting frame 95 drives the brush plate 15 to move transversely along the transverse plate 93, the limiting rod 19 will slide along the surface of the wave plate 20, and the limiting rod 19 can move up and down, thereby driving the connecting plate 17, the pressing rod 16 and the brush plate 15 to move up and down, so as to clean the filter holes 141 in depth. In this step, through the cooperation of the limiting rod 19 and the wave plate 20, the brush plate 15 can move transversely to adapt to the change of the diameter of the filter plate 14, and can also move up and down to clean the filter holes 141 in depth, which is convenient and fast.

[0066] Referring to Figure 8 In this embodiment, a rotating rod 21 is movably arranged in the middle of the moving frame 92, curve grooves 211 are symmetrically arranged on both ends of the rotating rod 21 in the axial direction, and the end of the limiting frame 95 away from the brush plate 15 is in sliding fit with the curve grooves 211.

[0067] Specifically, when the moving frame 92 moves transversely along the fixed rod 91, the rotating rod 21 rotates, and the rotation of the rotating rod 21 will make the limiting frames 95 on both sides first move away from each other, so that the brush plate 15 can clean more filter holes 141. When the limiting frame 95 moves to the end relative to the curve groove 211, at this time, the brush plates 15 on both sides are farthest away from each other, and the moving frame 92 moves to the middle position of the filter plate 14. Continue to move the moving frame 92 in the same direction, and rotate the rotating rod 21 in the same direction, and the limiting frame 95 will move reversely under the action of the curve groove 211, so that the limiting frames 95 on both ends move close to each other, and the brush plates 15 also move close to each other correspondingly. Because the diameter of the filter plate 14 is decreasing at this time, the rotation of the rotating rod 21 can adjust the positions of the limiting frame 95 and the brush plate 15.

[0068] Referring to Figure 7 and Figure 8 In this embodiment, a gear 22 is fixedly arranged on the outside of the middle of the rotating rod 21, a rack 23 is transversely fixedly arranged in the cylinder 12, the rack 23 is in sliding connection with the moving frame 92, and the gear 22 is in meshing transmission with the rack 23.

[0069] Specifically, when the moving frame 92 moves transversely along the fixed rod 91, the gear 22 will mesh with the rack 23, so as to realize the rotation of the gear 22 and the rotating rod 21. One rotation of the rotating rod 21 can make the brush plates 15 on both sides first move away from each other and then move close to each other, so as to adapt to the change of the diameter of the filter plate 14 in the moving process, and clean the filter holes 141 in depth.

[0070] Referring to Figures 10-11As shown, in this embodiment, the limiting frame 95 is fixedly installed with a positioning block 24 on one side, the positioning block 24 is movably installed with a moving rod 25 on one side, the moving rod 25 is fixedly provided with a push plate 26 on the end away from the positioning block 24, and the push plate 26 is in sliding fit with the surface of the filter plate 14.

[0071] Specifically, the movement of the limiting frame 95 away from each other will drive the positioning block 24, the moving rod 25 and the push plate 26 to move synchronously, the push plate 26 slides along the surface of the filter plate 14, and the push plate 26 away from each other can push the labels on the middle position of the filter plate 14 to the edge position, so that the labels on the surface of the filter plate 14 can be discharged through the discharge bin 13 during the rotation of the filter plate 14.

[0072] Referring to Figures 10-11 As shown, in this embodiment, a vertical groove 241 is formed in the positioning block 24, the moving rod 25 is in sliding connection with the vertical groove 241, a disc 27 is fixedly sleeved on the outside of the moving rod 25, a clamping rod 28 is movably sleeved on the outside of the disc 27 on one side, a limiting block 29 is fixedly arranged on one side of the positioning block 24, a clamping groove 291 is formed in the limiting block 29, the clamping rod 28 is movably clamped with the clamping groove 291, and the clamping rod 28 is fixedly connected with the disc 27 through a torsion spring 30.
