Description

Technical Field

[0001] The invention belongs to the technical field of automatic sorting equipment, in particular to a plastic bottle sorting equipment. Background Art

[0002] Plastic bottles have the advantages of light weight, good barrier properties, high transparency, high strength, low cost, acid and alkali resistance and high safety of use. Plastic bottles are mostly disposable, and a large number of plastic bottles are discarded after use. These plastic bottles are scattered in nature and are difficult to degrade naturally. If they are not recycled, they will cause serious ecological pollution. Therefore, the recycling of waste plastics can not only protect the ecological environment and be environmentally friendly, but also achieve sustainable economic development. Plastic bottles of different colors have different materials after decomposition, and the plastic materials of the bottle cap and the bottle body are also different. Therefore, plastic bottles of different colors as well as the bottle caps and the bottle body must be sorted.

[0003] The prior art also proposes some solutions: For example, a patent application with publication number CN106733726A discloses a plastic bottle sorting device: comprising a first conveyor belt, a detection mechanism is arranged above the first conveyor belt, the detection mechanism comprises a white strong light source and a black absorption block, a positive temperature coefficient thermistor is also arranged on the black absorption block, and a receiving mechanism is arranged below the output end of the first conveyor belt, the receiving mechanism comprises a frame, a mounting seat and a connecting plate. This solution does not require manual participation in the sorting of plastic bottles, which fully solves the problem of high costs caused by manual sorting.

[0004] In the prior art, most plastic bottle sorting is based on the color of the bottle body. Currently, the bottle caps cannot be processed during sorting.

[0018] The beneficial effects of the present invention are as follows:

[0019] 1. The plastic bottle sorting equipment described in the present invention has the effect of separating the bottle body and the bottle cap by making the internal device adapt to the height of the plastic bottle through the bottle cap separation mechanism. The outer circle of the twist-off piece is movably connected with the outer circle of the twist-off cap through an adjusting tube.

In this way, adaptive adjustment can be performed according to the height of the bottle body, and the position can be better adjusted to separate the bottle cap and the bottle body. When the hinged piece rotates at a high speed, the cap of the plastic bottle can be knocked off.

[0020] 2. The plastic bottle sorting equipment described in the present invention has the effect of slowly loosening the clamped bottle and letting it fall automatically through the twisting-off piece. When the left-handed main disk rotates to the point where it just meshes with the teeth on the left-handed secondary disk, the support column will perform a left-handed movement with the left-handed main disk. When the left-handed main disk rotates to an angle without teeth, the right-handed main disk just meshes with the teeth on the right-handed secondary disk. At this time, the support column will perform a right-handed movement with the right-handed main disk. The limiting groove on the support column and the limiting bead are just engaged together, so when the support column rotates, the movement of the twisting-off cap can be controlled by the limiting bead. When the plastic bottle rotates to the axis of the twisting-off cap, the twisting-off cap is first rotated right to connect with the clamping piece, and then the left-handed control clamping piece releases the plastic bottle. At this time, the plastic bottle will fall off due to its own gravity if it continues to rotate.

[0021] 3. The plastic bottle sorting equipment described in the present invention has the effect of clamping plastic bottles by replacing components. The plastic bottles are squeezed downward through the replacement holes. When the start cap contacts this pressure, the start cap will control the rotating column to rotate and move downward along the limiting tube. The limiting ring will be displaced downward as the rotating column rotates. The limiting ring controls the clamping part to rotate downward through the adjusting frame, and the clamping part will control the clamping part to contract and clamp the plastic bottle.

DETAILED DESCRIPTION

[0033] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0034] like Figures 1 to 3 As shown, a plastic bottle sorting device according to an embodiment of the present invention comprises a sorting machine housing 1, inside of which a bottle cap separating mechanism 100, a replacement assembly 200 and a sorting mechanism 300 are fixedly installed;

[0035] The bottle cap separation mechanism 100 is used to separate the bottle cap from the bottle body, the replacement assembly 200 is used to clamp the unidentified plastic bottles and loosen the identified plastic bottles, and the sorting mechanism 300 is used to respectively collect the identified plastic bottles and bottle caps of different types;

[0036] The sorting mechanism 300 includes a first sorting box 301, a plurality of chutes 302 are provided on the inner wall of the sorting machine housing 1, and sliders 303 are slidably connected to the inner walls of the chutes 302, wherein the outer wall of one slider 303 is fixedly connected to the outer wall of the first sorting box 301, and the outer wall of the other slider 303 is fixedly connected to the second sorting box 304, a near-infrared spectrometer 305 is fixedly provided on the inner wall of the sorting machine housing 1, a separation tube 307 is fixedly provided on the inner wall of the sorting machine housing 1, and a third sorting box 308 is fixedly installed inside the sorting machine housing 1;

[0037] When working, the sorting machine housing 1 is an opaque shell for sorting plastic bottles. Because the necessary step of plastic sorting is to sort according to the color of the plastic bottles themselves, there are certain requirements for the light in the scene when picking plastics. During sorting, the plastic bottles to be sorted are first placed in the replacement component 200 by a manipulator, and then the bottle caps and the bottle bodies are separated by the bottle cap separation mechanism 100. The near-infrared spectrometer 305 irradiates the plastic bottles through the light-transmitting holes, and then the plastic bottles are divided into transparent and colored according to the light feedback data. The slider 303 is controlled by the light source data. When the plastic bottle detected at this moment is transparent, the first sorting box 301 slides to the right along one of the slide slots 302 to prepare to receive the transparent plastic bottle. If the detected plastic bottle is colored, the second sorting box 304 will slide to the left to prepare to receive the colored plastic bottle, and the bottle cap will fall into the third sorting box 308. The sorting mechanism 300 has the effect of sorting the colored plastic bottles and the transparent plastic bottles and separating the bottle caps and the bottle bodies.

[0038] like Figures 7 to 9 As shown, the bottle cap separation mechanism 100 includes a separation shell 101, the outer wall of the separation shell 101 is provided with a fixing column 102, the outer wall of the fixing column 102 is provided with a fixing piece 103, the other end of the fixing column 102 is provided with an adjusting gear 104, the inner wall of the fixing piece 103 is provided with a left-handed gear 105, the inner wall of the left-handed gear 105 is provided with a left-handed column 106, the outer wall of the left-handed column 106 is rotatably connected with a right-handed column 107, one end of the right-handed column 107 is fixedly connected with a right-handed gear 108, the outer wall of the right-handed gear 108 contacts the inner wall of the fixing piece 103, and the teeth of the left-handed gear 105 and the right-handed gear 108 are both meshed with the teeth of the adjusting gear 104;

[0039] During operation, when the replacement component 200 rotates with the plastic bottle to face the bottle cap separation mechanism 100, the left-handed gear 105 rotates counterclockwise, and the left-handed column 106 also rotates counterclockwise due to its fixed connection with the left-handed gear 105. Because the left-handed gear 105 is meshed with the adjusting gear 104, the adjusting gear 104 also rotates. Because the adjusting gear 104 is meshed with the right-handed gear 108, the right-handed gear 108 and the right-handed column 107 perform clockwise motion together. Through the gear set, the right-handed column 107 and the left-handed column 106 are controlled to rotate in opposite directions respectively.

[0040] like Figures 8 to 9 As shown, the outer wall of the separation shell 101 is provided with a screw-off piece 109, the outer wall of the screw-off piece 109 is fixedly installed with an adjusting tube 110, the other end of the adjusting tube 110 is fixedly installed with a limiting bead 111, a screw-off cap 112 is fixedly provided between the outer wall of the limiting bead 111 and the outer wall of the adjusting tube 110, and the outer wall of the screw-off piece 109 is provided with a hinged piece 113;

[0041] When the bottle is in the state of being pressed down, the cap 112 is rotated to the left and connected with the clamping member 203, and then the clamping member 203 is rotated to the left to release the bottle.

[0042] like Figures 8 to 9 As shown, a secondary transmission member 114 is provided at one end of the hinged member 113, and the other end of the secondary transmission member 114 is fixedly mounted on the outer wall of the separation shell 101, and a primary transmission member 115 is fixedly mounted on the other end of the secondary transmission member 114, and the other end of the primary transmission member 115 is fixedly mounted on the outer wall of the left-handed column 106;

[0043] During operation, because there is a common rotating column 206 between the primary transmission member 115 and the secondary transmission member 114, when the primary transmission member 115 rotates, the secondary transmission member 114 also rotates accordingly. The secondary transmission member 114 controls the hinged member 113 to rotate at high speed, and the transmission of the transmission member is controlled by the left-hand column 106, so that the hinged member 113 rotates at high speed.

[0044] like Fig. 9 As shown, the outer wall of the left-hand column 106 is provided with a left-hand main disk 117, and the outer wall of the right-hand column 107 is provided with a right-hand main disk 118;

[0045] During operation, when the left-hand column 106 rotates leftward, it controls the left-hand main disk 117 to perform a left-hand movement. When the right-hand column 107 rotates, the right-hand main disk 118 also performs a right-hand movement. Through the reverse rotation of the left-hand column 106 and the right-hand column 107, the reverse rotation of the left-hand main disk 117 and the right-hand main disk 118 are controlled respectively.

[0046] like Fig. 9 As shown, a support column 119 is fixedly installed on the outer wall of the separation shell 101, a left-handed secondary disk 120 is arranged on the outer wall of the support column 119, a right-handed secondary disk 121 is arranged on the outer wall of the support column 119, the right-handed main disk 118 is meshed with the right-handed secondary disk 121, the left-handed secondary disk 120 is meshed with the left-handed main disk 117, and a limiting groove 122 is provided on the outer wall of the support column 119;

[0047] During operation, when the left-handed main disk 117 rotates to the point where it just meshes with the teeth on the left-handed secondary disk 120, the support column 119 performs a left-handed motion along with the left-handed main disk 117. When the left-handed main disk 117 rotates to an angle where there are no teeth, the right-handed main disk 118 just meshes with the teeth on the right-handed secondary disk 121. At this time, the support column 119 performs a right-handed motion along with the right-handed main disk 118. The limiting groove 122 on the support column 119 is just snapped together with the limiting bead 111. Through the structures such as the limiting groove 122 and the limiting bead 111, the displacement of the unscrewing cap 112 is controlled.

[0048] like Figures 7 and 8 As shown, a motor 116 is fixedly mounted on the outer wall of the separation shell 101, and the output shaft of the motor 116 is fixedly connected to the left-hand column 106;

[0049] During operation, the motor 116 starts to provide power to the left-handed column 106 , and the left-handed column 106 rotates, and the motor 116 controls the operation of the bottle cap separation mechanism 100 .

[0050] like Figure 4 As shown, the outer wall of the replacement component 200 is provided with a plurality of replacement holes 201, the interior of the replacement component 200 is provided with an angle adjustment member 202, and the outer wall of the angle adjustment member 202 is provided with a light-transmitting hole;

[0051] During operation, when the plastic bottle is loaded into the replacement hole 201, the pressure piece 208 will be subjected to a downward pressure, and the pressure piece 208 will press the angle adjustment piece 202 downward along this force. The angle adjustment piece 202 will rotate an angle each time it is subjected to a force. Through the rotation of the angle adjustment piece 202, the plastic bottles can be detected and sorted in sequence.

[0052] like Figures 4 to 6 As shown, a plurality of replacement holes 201 are provided with clamping members 203 inside, an adjusting frame 204 is fixedly installed on the outer wall of the clamping member 203, a limiting ring 205 is fixedly connected to the other end of the adjusting frame 204, a rotating column 206 is fixedly connected to the inner wall of the limiting ring 205, a starting cap 207 is fixedly installed on one end of the rotating column 206, a pressure member 208 is threadedly connected to the other end of the rotating column 206, a limiting tube 209 is threadedly connected to the outer wall of the limiting tube 209, an outer wall of the limiting tube 209 is fixedly connected to the outer wall of the replacement hole 201, a clamping member 210 is provided on the inner wall of the clamping member 203, one end of the clamping member 210 is fixedly connected to the outer wall of the limiting tube 209, and the pressure member 208 is meshed with the angle of the angle adjustment member 202;

[0053] During operation, the plastic bottle is squeezed downward through the replacement hole 201. When the start cap 207 comes into contact with this pressure, the start cap 207 will control the rotating column 206 to rotate and move downward along the limiting tube 209. The limiting ring 205 is displaced downward as the rotating column 206 rotates. The limiting ring 205 controls the clamping member 203 to rotate and move downward through the adjusting frame 204. The clamping member 203 will gradually shrink as it moves downward along the replacement hole 201 and control the clamping member 210 to shrink and clamp the plastic bottle. The replacement component 200 can achieve the effect of clamping the plastic bottle according to its size.

[0054] like Figure 1 As shown, a feed port 306 is provided on the outer wall of the separator housing 1;

[0055] During operation, the robot arm controls the plastic bottles to be placed into the interior of the sorting machine housing 1 through the feed port 306 .

[0056] Working principle: The robot arm controls the plastic bottle to be placed into the interior of the sorting machine housing 1 through the feed port 306, and the plastic bottle is squeezed downward through the replacement hole 201. When the start cap 207 contacts this pressure, the start cap 207 will control the rotating column 206 to rotate and move downward along the limiting tube 209, and the limiting ring 205 will be displaced downward as the rotating column 206 rotates. The limiting ring 205 controls the clamping member 203 to rotate downward through the adjustment frame 204, and the clamping member 203 will control the clamping member 210 to contract and clamp the plastic bottle. When the plastic bottle is loaded into the replacement hole 201, the pressure member 208 will be subjected to a downward pressure, and the pressure member 208 will squeeze the angle adjustment member 202 downward along this force. The angle adjustment member 202 will rotate one angle each time it is subjected to a force. When the plastic bottle rotates to the axis of the screw-off cap 112, the motor 116 starts to provide power for the left-handed column 106, and the left-handed column 106 rotates. The left-handed column 106 also performs a left-handed motion due to its fixed connection with the left-handed column 106. Because the left-handed gear 105 is meshed with the adjusting gear 104, the adjusting gear 104 also rotates. Because the adjusting gear 104 is meshed with the right-handed gear 108, the right-handed gear 108 and the right-handed column 107 perform a right-handed motion together. When the left-handed column 106 rotates to the left, the left-handed main disk 117 is controlled to perform a left-handed motion. When the right-handed column 107 rotates, the right-handed main disk 118 also performs a right-handed motion accordingly. The left-handed secondary disk 120 and the right-handed secondary disk 121 are meshed with the teeth of the left-handed main disk 117 and the right-handed main disk 118 respectively. When the disk 117 rotates to the point where it just meshes with the teeth on the left-handed secondary disk 120, the support column 119 performs a left-handed motion with the left-handed main disk 117. When the left-handed main disk 117 rotates to an angle without teeth, the right-handed main disk 118 just meshes with the teeth on the right-handed secondary disk 121. At this time, the support column 119 performs a right-handed motion with the right-handed main disk 118. The limiting groove 122 on the support column 119 is just snapped together with the limiting bead 111. Therefore, when the support column 119 rotates, the movement of the screw-off cap 112 can be controlled by the limiting bead 111. Because there is a common rotating column 206 between the primary transmission member 115 and the secondary transmission member 114, when the primary transmission member 115 rotates, the secondary transmission member 114 also rotates accordingly. The hinged member 113 is controlled to rotate at a high speed, and the outer ring of the twisting member 109 is movably connected with the outer ring of the twisting cap 112 through the adjusting tube 110. When the limiting bead 111 is subjected to an external force, the limiting bead 111 drives the adjusting tube 110 to squeeze and rotate or stretch and rotate, thereby controlling the twisting cap 112 to move and rotate, thereby making adaptive adjustment according to the height of the bottle body, and better adjusting the position to separate the bottle cap and the bottle body. When the hinged member 113 rotates at a high speed, the lid of the plastic bottle can be knocked off. At the same time, because the twisting cap 112 is firstly rotated right to connect with the clamping member 203, and then rotated left to control the clamping member 203 to release the plastic bottle, the plastic bottle will fall off due to its own gravity if it continues to rotate, and finally the plastic bottle is sorted.
