Description

Technical Field

[0001] This invention relates to the field of empty bottle recycling technology, and in particular to a bottle flattening recycling machine, a rolling blade, and a flattening mechanism. Background Technology

[0002] Waste plastic bottles and cans can be recycled and reused, and they have many uses after recycling. Many people throw plastic bottles and cans directly into the trash can for convenience, which requires sanitation workers to collect them. Moreover, when recycling plastic bottles and cans, because the bottles are large, they need to be squeezed or flattened manually before they can be recycled, which consumes a lot of manpower and is inefficient. Summary of the Invention

[0003] In view of this, the present invention addresses the deficiencies of the prior art, and its main objective is to provide a bottle flattening and recycling machine, a rolling blade, and a flattening mechanism. The bottle flattening and recycling machine can automatically flatten bottles, saving time and effort and achieving high efficiency.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] In a first aspect, a bottle flattening and recycling machine includes a body, the body including a flattening mechanism for flattening bottles and a pressing mechanism for pressing bottles against the bottle input side of the flattening mechanism. The flattening mechanism includes two rollers arranged side by side and a flattening drive mechanism for controlling the two rollers to rotate in opposite directions. Each roller has a plurality of rolling blades arranged axially at intervals. The rolling blades on the two rollers are staggered and meshed. Each rolling blade has a predetermined number of sharp teeth for biting the bottle at equal intervals along the circumferential direction on its side. In the rolling direction of the rolling blade, each sharp tooth has an inward concave arc-shaped groove for preventing the bottle from being clamped and an outward protrusion for arching out the sharp tooth biting the bottle, respectively, in front of and behind each sharp tooth. Each outward protrusion is connected to the inward concave arc-shaped groove adjacent to its rear side by a flattening part.

[0006] As a preferred embodiment, the pressing mechanism includes pressing plates, a rotating shaft, and a pressing drive mechanism for driving the rotating shaft to rotate. The number of the aforementioned sharp teeth is an integer multiple of the number of pressing plates. The pressing plates are equidistantly connected to the rotating shaft along the circumferential direction. The machine body is provided with a guide baffle. The guide baffle is arranged opposite to the pressing mechanism at intervals, and the interval between the guide baffle and the pressing mechanism forms a bottle channel that connects to the bottle input side of the flattening mechanism.

[0007] As a preferred embodiment, each of the pressure plates includes a connecting section, a first bending section, a second bending section, and a third bending section connected in sequence. The connecting section is connected to a rotating shaft. The bending angle between the first bending section and the connecting section is 10°-20°, the bending angle between the second bending section and the first bending section is 20°-40°, and the bending angle between the third bending section and the second bending section is 90°. A bottle-accommodating space is formed between two adjacent pressure plates.

[0008] As a preferred embodiment, the first bending section, the second bending section, and the third bending section are all provided with multiple anti-slip protrusions on their pressing surfaces.

[0009] As a preferred embodiment, the guide baffle is swayably connected to the machine body on one side at the bottle channel inlet, and the guide baffle is swayably connected to the machine body on the other side at the bottle channel outlet, moving away from / closer to the pressing mechanism. The machine body is also provided with an elastic element that makes the guide baffle on the side at the bottle channel outlet always tend to move towards the pressing mechanism.

[0010] As a preferred embodiment, the bottle channel is divided into a first channel and a second channel along the length corresponding to the roller by a partition. Correspondingly, the bottle input side of the flattening mechanism is divided into a first input side and a second input side, and the bottle output side of the flattening mechanism is divided into a first output side and a second output side. Furthermore, the length of the first channel is greater than the length of the second channel.

[0011] As a preferred embodiment, the body is further provided with a paddle and a paddle drive mechanism for controlling the paddle to swing back and forth. The paddle is arranged to swing back and forth between the entrance of the first channel and the entrance of the second channel.

[0012] As a preferred embodiment, the connection between the first output side and the second output side is provided with a first guide plate for preventing the bottle falling from the first output side from shifting toward the second output side and a second guide plate for preventing the bottle falling from the second output side from shifting toward the first output side.

[0013] As a preferred embodiment, the flattening mechanism further includes a comb for cleaning residue. The comb is disposed on the bottle output side of the flattening mechanism, and the teeth of the comb extend one-to-one into the gap between two adjacent rolling blades on the same roller.

[0014] In a second aspect, a rolling blade is applied to the flattening mechanism described in the first aspect, wherein a predetermined number of sharp teeth for gripping bottles are provided at equal intervals along the rolling direction on the side of the rolling blade, and in the rolling direction of the rolling blade, each sharp tooth is provided with a concave arc-shaped groove for preventing the bottle from being clamped and an outward protrusion for arching out the sharp tooth that grips the bottle, and each of the outward protrusions is connected to a flattening part between it and the concave arc-shaped groove adjacent to its rear side.

[0015] Thirdly, a flattening mechanism is applied to the bottle flattening and recycling machine described in the first aspect. The flattening mechanism includes two rollers arranged side by side and a flattening drive mechanism for controlling the two rollers to rotate in opposite directions. Each roller has a plurality of rolling blades arranged axially at intervals. The rolling blades on the two rollers are staggered and meshed one by one. Each rolling blade has a predetermined number of sharp teeth for biting the bottle at equal intervals along the rolling direction on its side. Furthermore, in the rolling direction of the rolling blade, each sharp tooth has an inward concave arc-shaped groove for preventing the bottle from being clamped and an outward protrusion for arching out the sharp tooth that bites the bottle, respectively, in front of and behind it. Each outward protrusion is connected to a flattening part between itself and the adjacent inward concave arc-shaped groove on its rear side.

[0016] Compared with existing technologies, this invention has significant advantages and beneficial effects. Specifically, as can be seen from the above technical solution, it mainly achieves automatic bottle flattening by designing a flattening mechanism and a pressing mechanism. In practice, the pressing mechanism is used to press the bottle against the bottle input side of the flattening mechanism, while the flattening mechanism flattens the bottle. This achieves automatic bottle flattening, saving time and effort, and increasing efficiency. Specifically, the rolling blades of the flattening mechanism are designed with sharp teeth, concave arc grooves, and convex parts. During operation, the pressing mechanism firmly presses the bottle against the bottle input side of the flattening mechanism. At this time, the two rollers... The sharp teeth of the rolling blades bite into the sides of the bottle. Under the rolling action, the bottle is dragged into the meshing junction between the rolling blades on the two rollers and flattened by the flattening part. During the dragging process, because the concave arc groove is arc-shaped, compared with the sharp groove, the bottle will not be stuck and unable to get out. At the same time, under the action of the outward convex part, the sharp teeth biting into the bottle can be pushed out of the bottle. In this way, the rolling blades can automatically separate from the bottle, and the bottle can be continuously flattened. In addition, it should be noted that the outward convex part can also make the bottle flatter.

[0028] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0029] It should be noted that when a component is said to be "fixed to" another component, it can be directly attached to the other component or there may be an intervening component. When a component is said to be "connected to" another component, it can be directly connected to the other component or there may be an intervening component.

[0030] Please see Figures 1 to 8 This invention provides a bottle flattening and recycling machine, comprising a body 1. The body 1 includes a flattening mechanism 10 for flattening bottles and a pressing mechanism 20 for pressing bottles against the bottle input side 101 of the flattening mechanism 10. The flattening mechanism 10 includes two rollers 11 arranged side by side and a flattening drive mechanism 12 for controlling the two rollers 11 to rotate in opposite directions. Each roller 11 has a plurality of rolling blades 13 arranged axially at intervals. The rolling blades 13 on the two rollers 11 are staggered and meshed. Each rolling blade 13 has a predetermined number of sharp teeth 131 evenly spaced along the circumferential direction on its side for biting the bottle. It should be noted that the number of sharp teeth 131 on each rolling blade 13 is adapted to the outer diameter of the bottle. The larger the bottle, the fewer the number of sharp teeth 131 can be. The number of sharp teeth 131 is correspondingly increased. In this embodiment, preferably, there are six sharp teeth 131 on each rolling blade 13. In other embodiments, there may be five, eight, or other sharp teeth 131. In addition, in this embodiment, all the sharp teeth 131 on each roller 11 are arranged in a straight line. In other embodiments, the positions of all the sharp teeth 131 on each roller 11 may not be in a straight line, that is, the sharp teeth 131 are staggered. In the rolling direction of the rolling blade 13, each sharp tooth 131 is provided with an inward concave arc groove 132 for preventing the bottle from being clamped and an outward protrusion 133 for arching out the sharp tooth 131 that bites into the bottle. Furthermore, each outward protrusion 133 is connected to the inward concave arc groove 132 adjacent to its rear side by a flattening part 134.

[0031] By designing the rolling blades 13 of the flattening mechanism 10 with sharp teeth 131, concave arc grooves 132, and convex portions 133, during operation, the pressing mechanism 20 presses the bottle tightly against the bottle input side 101 of the flattening mechanism 10. At this time, the sharp teeth 131 of the rolling blades 13 on the two rollers 11 will bite the sides of the bottle. Under the rolling action, the bottle will be dragged into the junction between the rolling blades 13 on the two rollers 11 and flattened by the flattening portions 134 of the rolling blades 13 on the two rollers 11. During the dragging process, since the concave arc groove 132 is arc-shaped, compared with the sharp groove, the bottle will not be clamped and unable to come off. At the same time, under the action of the convex portion 133, the sharp teeth 131 biting the bottle can be pushed out of the bottle. In this way, the rolling blades 13 and the bottle can be automatically separated, and the bottle can be continuously flattened. In addition, it should be noted that the convex portion 133 can also make the bottle flatter.

[0032] Specifically, the pressing mechanism 20 includes pressing plates 21, a rotating shaft 22, and a pressing drive mechanism 23 that drives the rotating shaft 22 to rotate. The number of the aforementioned sharp teeth 131 is an integer multiple of the number of pressing plates 21. In this embodiment, there are three pressing plates 21. The pressing plates 21 are equidistantly connected to the rotating shaft 22 along the circumferential direction. The machine body 1 is provided with a guide baffle 30. The guide baffle 30 is arranged opposite to the pressing mechanism 20 at intervals, and the interval between the guide baffle 30 and the pressing mechanism 20 forms a bottle channel 301 that connects to the bottle input side 101 of the flattening mechanism 10. It should be noted that the pressing drive mechanism 23 and the flattening drive mechanism 12 are the same drive mechanism. When the flattening mechanism 10 is working, under the guidance of the guide baffle 30 and the pressing action of the pressing plate 21, the bottle is pushed by the pressing plate 21 and guided by the guide baffle 30, so that it can enter the bottle input side 101 of the flattening mechanism 10 from the bottle channel 301. When the bottle is located at the bottle input side 101 of the flattening mechanism 10, the pressing plate 21 will press against the bottle during rotation, so that the bottle cannot bounce away from the bottle input side 101 of the flattening mechanism 10. At the same time, the pressing plate 21 can also press the bottle into the junction between the rolling blades 13 on the two rollers 11 for flattening. It should be noted that in some other embodiments, the pressing mechanism 20 can also be other forms of structure, as long as it can press the bottle against the bottle input side 101 of the flattening mechanism 10, and is not limited thereto. For example, the bottle can be grasped by a robot and pressed against the bottle input side 101 of the flattening mechanism 10, which is also acceptable.

[0033] Furthermore, each of the aforementioned pressure plates 21 includes a connecting section 211, a first bending section 212, a second bending section 213, and a third bending section 214 connected in sequence. The connecting section 211 is connected to the rotating shaft 22. The bending angle between the first bending section 212 and the connecting section 211 is 10°-20°, the bending angle between the second bending section 213 and the first bending section 212 is 20°-40°, and the bending angle between the third bending section 214 and the second bending section 213 is 90°. A bottle-accommodating space 215 is formed between two adjacent pressure plates 21. During operation, the worker can feed the bottle into the bottle-containing space 215. When the bottle-containing space 215 rotates to a certain angle, the bottle will fall from the bottle-containing space 215 into the bottle input side 101 of the flattening mechanism 10. Then, as the rotation continues, the pressure plate 21 will press against the bottle. For large bottles, the first bending section 212, the second bending section 213, and the third bending section 214 will contact them in turn. The third bending section 214 can prevent the bottle from bouncing. For smaller bottles, the first bending section 212 does not contact the small bottle, but the second bending section 213 and the third bending section 214 will contact it in turn. If these bending sections are not provided, and the pressure plate 21 is just a straight plate, it will not be easy to press the bottle against the bottle input side 101 of the flattening mechanism 10, but will push the bottle away instead.

[0034] Furthermore, the first bending section 212, the second bending section 213, and the third bending section 214 are all provided with multiple anti-slip protrusions (not shown in the figure) on their pressing surfaces. The anti-slip protrusions can prevent slipping when pressing the bottle.

[0035] Furthermore, the guide baffle 30 is swayably connected to the machine body 1 on one side at the entrance of the bottle channel 301, and the guide baffle 30 is swayably connected to the machine body 1 on the other side at the exit of the bottle channel 301, moving away from / closer to the pressing mechanism 20. Here, the swaying angle range of the guide baffle 30 is 0-30°. The machine body 1 is also provided with an elastic element 31 that makes the side of the guide baffle 30 at the exit of the bottle channel 301 always tend to move towards the pressing mechanism 20. The elastic element 31 is a spring. In this way, the exit of the bottle channel 301 can have the characteristic of variable size, so that bottles of different sizes can stably enter the bottle channel 301. If the size of the exit of the bottle channel 301 cannot be changed, then smaller bottles will not be easily guided into the bottle input side 101 of the flattening mechanism 10, which will cause the pressing plate 21 to not accurately press the bottle.

[0036] Furthermore, the bottle channel 301 is divided into a first channel 302 and a second channel 303 along the length corresponding to the roller 11 by a partition 304. Correspondingly, the bottle input side 101 of the flattening mechanism 10 is divided into a first input side 102 and a second input side 103, and the bottle output side 104 of the flattening mechanism 10 is divided into a first output side 105 and a second output side 106. The length of the first channel 302 is greater than the length of the second channel 303. In this way, two working positions can be formed. The first channel 302 is used to transport longer bottles, while the second channel 303 is used to transport shorter bottles. This can improve the flattening efficiency. Finally, the flattened bottles will fall out from the first output side 105 and the second output side 106 respectively, which also facilitates the classification and recycling of different bottles.

[0037] Furthermore, the machine body 1 is also equipped with a lever 40 and a lever drive mechanism 41 that controls the lever 40 to swing back and forth. The lever 40 is oscillating back and forth between the entrance of the first channel 302 and the entrance of the second channel 303. The lever 40 can prevent the bottle from popping out. During operation, when the lever 40 swings towards the entrance of the first channel 302, the operator can put the bottle into the entrance of the second channel 303. Then, under the action of the lever drive mechanism 41, the lever 40 swings towards the entrance of the second channel 303 to prevent the bottle from popping out of the entrance of the second channel 303. At this time, the operator can put the bottle into the entrance of the first channel 302. Then, under the action of the lever drive mechanism 41, the lever 40 swings towards the entrance of the first channel 302 to prevent the bottle from popping out of the entrance of the first channel 302. This cycle continues.

[0038] Furthermore, the connection between the first output side 105 and the second output side 106 is provided with a first guide plate 50 for preventing bottles falling from the first output side 105 from shifting toward the second output side 106 and a second guide plate 51 for preventing bottles falling from the second output side 106 from shifting toward the first output side 105, so as to ensure the normal operation of sorting and recycling.

[0039] Furthermore, the flattening mechanism 10 also includes a comb tooth 14 for cleaning residues. The comb tooth 14 is disposed on the bottle output side 101 of the flattening mechanism 10. The comb teeth of the comb tooth 14 extend into the gap between two adjacent rolling blades 13 on the same roller 11. During the rolling flattening process, when bottle residues remain in the gap between two adjacent rolling blades 13, the bottle residues will be removed by the comb teeth of the comb tooth 14 under the action of the comb teeth, thus ensuring the normal operation of the flattening work.

[0040] 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 and improvements made within the principles of the present invention should be included within the protection scope of the present invention.
