Description

Technical Field

[0001] This utility model belongs to the field of plastic bottle processing and production, and in particular relates to a lightweight and environmentally friendly plastic bottle cap conveying device. Background Technology

[0002] In the plastic bottle manufacturing industry, bottle bodies and caps are generally processed and produced separately, and then assembled in the assembly room. Currently, bottle caps are mainly transported between processing areas using belt conveyor tracks. During the transport process, bottle caps are usually transported face up to facilitate subsequent assembly. However, in actual transport, due to human or machine errors, some bottle caps may be placed in the wrong orientation. In such cases, manual inspection and sorting are usually required, which is not only inefficient but also prone to errors.

[0003] The existing patent CN216944968U discloses a plastic bottle cap conveying device, which includes a track. A horizontal bar located above the track is connected to the side wall of the track via a vertical rod. A sliding rod is vertically movable on the horizontal bar. One end of the sliding rod is connected to a pressure plate above the horizontal bar, and the other end extends below the horizontal bar and is connected to a roller frame. An abutting roller is rotatably mounted on the roller frame, and the abutting roller abuts against the top of a bottle cap placed in the track. The sliding rod located below the horizontal bar... A first spring is fitted onto the upper part of the device. One end of the first spring is connected to the crossbar, and the other end is connected to the roller frame. An alarm component is also provided on the crossbar. This solves the problem that bottle caps may be misplaced during the conveying process. Manually observing and picking them is not only inefficient but also prone to errors. However, before the bottle caps enter the conveying device, the vibration and shaking in the bottle cap feeder can cause the bottle caps to be misoriented, preventing them from entering the conveying device correctly and individually. Incorrectly oriented bottle caps need to be manually corrected before processing, which not only reduces the efficiency of bottle cap conveying but also reduces the production volume of bottle caps. Utility Model Content

[0004] The purpose of this invention is to address the aforementioned technical problems by providing a lightweight and environmentally friendly plastic bottle cap conveying device. This device can correct the position of the bottle caps during feeding, making the conveying device more efficient in transporting bottle caps and improving the production efficiency of bottle caps.

[0005] In view of this, the present invention provides a lightweight and environmentally friendly plastic bottle cap conveying device, characterized in that it includes a frame, on which are arranged:

[0006] A supply box is fixedly mounted on the frame, and the supply box has an upward-facing feed inlet;

[0007] A guiding device is disposed on the side of the supply box, and the guiding device is used to restrict the conveying path of the bottle caps;

[0008] A feeding device is installed inside the supply box. One end of the feeding device passes through the supply box and is connected to the feed end of the orientation device. The feeding device is used to feed bottle caps out of the supply box and into the orientation device.

[0009] In this technical solution, bottle caps are fed into the supply box through the inlet. The bottle caps are then conveyed into the orientation device by the feeding device. Since the orientation device restricts the conveying route of the bottle caps, the movement path of the bottle caps is corrected during the process of passing through the orientation device, and they are conveyed according to the specified path, thereby improving the conveying efficiency of the bottle caps.

[0010] Furthermore, a feeding groove is provided on the side of the supply box, and one end of the feeding device passes through the feeding groove and is fixedly connected to the supply box. There is a gap between the feeding groove and the feeding device, and the height of the gap is adapted to the height of a single bottle cap.

[0011] In this technical solution, the feeding device can use belt drive to transport bottle caps. When the bottle caps are transported through the feeding groove, the gap between the feeding groove and the feeding device allows the bottle caps to pass through in a single layer, preventing the bottle caps from overlapping and affecting the subsequent processing of the bottle caps.

[0012] Furthermore, a base plate is horizontally arranged at the bottom of the orientation device. The base plate is fixedly connected to the frame and is inclined. The end of the base plate near the supply box is higher than the other end of the base plate.

[0013] In this technical solution, the tilting of the base plate allows the bottle cap to move along the path of the orientation device under the action of gravity, saving energy and reducing production costs.

[0014] Furthermore, the orientation device includes a first orientation part and a second orientation part. The first orientation part is disposed at one end of the feeding device and is used to restrict the movement path of multiple bottle caps. The second orientation part is fixedly disposed at one end of the first orientation part and is used to restrict the movement path of a single bottle cap.

[0015] Furthermore, the first directional part includes:

[0016] A cover plate, which is fixedly mounted on a base plate and connected to one end of the feeding device;

[0017] A straightening channel is provided with a cover plate on the side near the feeding device. Multiple straightening channels are horizontally arranged along the width direction of the base plate. The straightening channels are semi-cylindrical in shape, and the diameter of the straightening channel is larger than the diameter of the bottle cap.

[0018] An extension plate is fixedly installed at the end of the straightening channel away from the feeding device. There is a cap gap between the extension plate and the base plate. The extension plate is provided with cap outlet holes. Multiple cap outlet holes are horizontally arranged along the width direction of the base plate. The cap outlet holes are vertically arranged cylindrical holes. The diameter of the cap outlet holes is larger than that of the bottle cap. The position of the cap outlet holes corresponds to that of the straightening channel.

[0019] In this technical solution, the bottle cap enters the straightening channel through the feeding device, passes through the straightening channel in a straight path and through the cap outlet hole, and finally passes through the cap gap between the extension plate and the base plate, so that the bottle cap enters the second orientation section in an orderly manner.

[0020] Furthermore, the second directional part includes:

[0021] A transport plate, disposed on the side of an extension plate, is used to transform the transport of multiple bottle caps into the transport of a single bottle cap.

[0022] A sorting component is disposed at one end of a transport plate, and the sorting component is used to sort bottle caps with openings facing different directions;

[0023] An orientation component is disposed at one end of a sorting component, and the orientation component is used to unify the opening orientation of bottle caps;

[0024] An outlet plate, disposed at one end of the orientation assembly, is used to convey individual bottle caps to the next process.

[0025] Furthermore, a transport trough is provided in the middle of the transport plate. The front end of the transport trough is platform-shaped. The maximum width of the front end of the transport trough is adapted to the width of the feed trough. The minimum width of the front end of the transport trough is adapted to the diameter of the bottle cap. The rear end of the transport trough is rectangular. The width of the rear end of the transport trough is the same as the minimum width of the front end of the transport trough.

[0026] In this technical solution, the bottle caps enter the transport plate from the feeding groove and move along the path of the transport groove. Due to the limitation of the width of the rear end of the transport groove, the bottle caps can only pass through the transport groove one by one and enter the sorting component.

[0027] Furthermore, the classification component includes:

[0028] A branch track is provided at the rear end of the transport plate. The branch track includes an input track, a first output track, and a second output track. The width of the branch track is adapted to the diameter of the bottle cap.

[0029] A dial is provided on the movement path of the bottle cap on the branch track. The dial is disc-shaped and has three transmission slots on its outer circumference. The transmission slots are evenly distributed on the circumference of the servo dial, and the size of each transmission slot is designed to fit a single bottle cap.

[0030] A servo motor is fixedly mounted on the base plate, and the output end of the servo motor is connected to the center of the dial.

[0031] In this technical solution, the branch track input end receives bottle caps conveyed by the transport plate. A servo motor controls the rotation of a dial. The dial is configured to accommodate the bottle caps at the input end within its transmission slots. Depending on the opening orientation of the bottle cap, it guides the bottle cap to either the first or second output track. Each time the dial rotates 120 degrees, the bottle cap is transferred within the transmission slot to an input point near either the first or second output track, causing the other transmission slot to be positioned near the input end. When the bottle cap opening is downwards, the dial rotates clockwise to the first output track; when the bottle cap opening is upwards, the dial rotates counterclockwise to the second output track.

[0032] Furthermore, the first output track and the second output track are configured as cam paths, and the protruding part of the cam path is located at the interface between the dial transport groove and the first output track or the second output track.

[0033] In this technical solution, when the dial rotates toward the corresponding first output track or second output track, the protrusion on the cam path pushes the bottle cap out of the transmission groove to prevent the dial from getting stuck.

[0034] Furthermore, the orientation component includes:

[0035] A straight slide groove is connected to a first output track, and the width of the straight slide groove is adapted to the diameter of the bottle cap.

[0036] The spiral tube is installed on the base plate along its length. The spiral tube is connected to the second output track. The spiral tube has a spiral channel inside, and the rotation angle of the spiral channel is 180 degrees.

[0037] In this technical solution, the straight slide receives correctly oriented bottle caps (i.e., the openings of the bottle caps face downwards) from the first output track, while the spiral tube receives incorrectly oriented bottle caps (i.e., the openings of the bottle caps face upwards) from the second output track. The cross-section of the spiral channel input opening rotates 180 degrees along the length of the spiral tube, causing the output opening to be 180 degrees reversed from the input opening. Thus, when an incorrectly oriented bottle cap passes through the spiral tube, it will reverse, causing the bottle cap to enter the spiral tube with its opening facing upwards but exit with its opening facing downwards. This ensures that the bottle caps that finally enter the outlet plate all have their openings facing downwards.

[0038] The beneficial effects of this utility model are:

[0039] 1. This utility model enables the supply device to put bottle caps into the supply box through the opening. The bottle caps are then transported into the orientation device by the feeding device. Since the orientation device restricts the transport route of the bottle caps, the movement path of the bottle caps is corrected during the process of passing through the orientation device, and they are transported according to the specified path, thereby improving the transport efficiency of the bottle caps.

[0040] 2. This utility model enables the straight slide to receive correctly oriented bottle caps (i.e., the bottle cap openings face downwards) from the first output track, while the spiral tube receives incorrectly oriented bottle caps (i.e., the bottle cap openings face upwards) from the second output track. The cross-section of the spiral channel input opening rotates 180 degrees along the length of the spiral tube, so that the output opening is a 180-degree reversal of the input opening. This allows the bottle caps to enter the spiral tube with their openings facing upwards, but to leave the spiral tube with their openings facing downwards. As a result, the bottle caps that finally enter the outlet plate all have their openings facing downwards, which facilitates subsequent processing of the bottle caps. Attached image description:

[0054] Example 1:

[0055] like Figure 1-7 As shown, this utility model provides a lightweight and environmentally friendly plastic bottle cap 6 conveying device, including a frame 1, on which:

[0056] Supply box 2, which is fixedly mounted on frame 1, and the supply box has an upward feed port 21;

[0057] A guiding device is provided on the side of the supply box 2, and the guiding device is used to restrict the conveying route of the bottle cap 6;

[0058] Feeding device 3 is installed inside the supply box 2. One end of the feeding device 3 passes through the supply box 2 and is connected to the feed end of the orientation device. The feeding device 3 is used to feed the bottle cap 6 out of the supply box and into the orientation device.

[0059] Bottle cap 6 is fed into the supply box 2 through the feed inlet 21. Under the conveying of the feeding device 3, bottle cap 6 enters the orientation device. Since the orientation device restricts the conveying route of bottle cap 6, the movement route of bottle cap 6 is corrected during the process of passing through the orientation device, and it is conveyed according to the specified path, thereby improving the conveying efficiency of bottle cap 6.

[0060] The side of the supply box 2 is provided with a feeding groove 22. One end of the feeding device 3 passes through the feeding groove 22 and is fixedly connected to the supply box 2. There is a gap between the feeding groove 22 and the feeding device 3. The height of the gap is adapted to the height of a single bottle cap 6.

[0061] The feeding device 3 can use belt drive to transport the bottle cap 6. When the bottle cap 6 is transported through the feeding groove 22, the gap between the feeding groove 22 and the feeding device 3 allows the bottle cap 6 to pass through in a single layer, preventing the bottle cap 6 from being stacked and affecting the subsequent processing of the bottle cap 6.

[0062] The bottom of the orientation device is provided with a base plate 7 horizontally. The base plate 7 is fixedly connected to the frame 1. The base plate 7 is inclined. The end of the base plate 7 near the supply box 2 is higher than the other end of the base plate 7.

[0063] The tilting of the base plate 7 allows the bottle cap 6 to move along the path of the orientation device under the action of gravity, saving energy and reducing production costs.

[0064] The orientation device includes a first orientation part 4 and a second orientation part 5. The first orientation part 4 is disposed at one end of the feeding device 3 and is used to restrict the movement path of multiple bottle caps 6. The second orientation part is fixedly disposed at one end of the first orientation part 4 and the second orientation part 5 is used to restrict the movement path of a single bottle cap 6.

[0065] The first orientation unit 4 includes:

[0066] Cover plate 41, the cover plate 41 is fixedly mounted on the base plate 7, and the cover plate 41 is connected to one end of the feeding device 3;

[0067] A straightening channel 42 is provided with a cover plate 41 on the side near the feeding device 3. Multiple straightening channels 42 are horizontally arranged along the width direction of the base plate 7. The straightening channel 42 is semi-cylindrical in shape, and the diameter of the straightening channel 42 is larger than the diameter of the bottle cap 6.

[0068] An extension plate 44 is fixedly disposed at one end of the straightening channel 42 away from the feeding device 3. There is a cap clearance between the extension plate 44 and the base plate 7. The extension plate 44 is provided with cap outlet holes 43. Multiple cap outlet holes 43 are horizontally arranged along the width direction of the base plate 7. The cap outlet holes 43 are vertically arranged cylindrical holes. The diameter of the cap outlet holes 43 is larger than that of the bottle cap 6. The position of the cap outlet holes 43 corresponds to that of the straightening channel 42.

[0069] The bottle cap 6 enters the straightening channel 42 through the feeding device 3. The bottle cap 6 passes through the straightening channel 42 in a straight path and passes through the cap outlet 43. Finally, the bottle cap 6 passes through the cap gap between the extension plate 44 and the base plate 7, so that the bottle cap 6 enters the second orientation section 5 in an orderly manner.

[0070] The second directional unit 5 includes:

[0071] A transport plate 51 is disposed on the side of the extension plate 44, and the transport plate 51 is used to transform the transport of multiple bottle caps 6 into the transport of a single bottle cap 6.

[0072] A sorting component 52 is disposed at one end of a transport plate 51, and the sorting component 52 is used to sort bottle caps 6 with different opening orientations;

[0073] Orientation component 53, which is disposed at one end of classification component 52, is used to unify the opening orientation of bottle cap 6;

[0074] An outlet plate, disposed at one end of the orientation assembly 53, is used to convey a single bottle cap 6 to the next process.

[0075] The transport plate 51 has a transport groove 511 in the middle. The front end of the transport groove 511 is platform-shaped. The maximum width of the front end of the transport groove 511 is adapted to the width of the feed groove 22. The minimum width of the front end of the transport groove 511 is adapted to the diameter of the bottle cap 6. The rear end of the transport groove 511 is rectangular. The width of the rear end of the transport groove 511 is the same as the minimum width of the front end of the transport groove 511.

[0076] Bottle caps 6 enter the transport plate 51 from the feed groove 22. Bottle caps 6 move along the path of transport groove 511. Due to the limitation of the width of the rear end of transport groove 511, bottle caps 6 can only pass through transport groove 511 one by one and enter the sorting component 52.

[0077] Example 2:

[0078] like Figure 1-7 As shown, the classification component 52 includes:

[0079] A branch track is provided at the rear end of the transport plate 51. The branch track includes an input track 521, a first output track 522, and a second output track 523. The width of the branch track is adapted to the diameter of the bottle cap 6.

[0080] A dial 524 is provided on the movement path of the bottle cap 6 on the branch track. The dial 524 is disc-shaped and has three transmission slots 525 on its outer circumference. The transmission slots 525 are equidistantly distributed on the circumference of the servo dial 524, and the size of each transmission slot 525 is designed to fit a single bottle cap 6.

[0081] Servo motor 527 is fixedly mounted on base plate 7, and the output end of servo motor 527 is connected to the center of dial 524.

[0082] The branch track input end receives bottle caps 6 from the transport plate 51. A servo motor 527 controls the rotation of a dial 524. The dial 524 is configured to accommodate the bottle caps 6 at the input end within its transmission slot 525. Depending on the opening orientation of the bottle caps 6, the dial guides them to either the first output track 522 or the second output track 523. Each time the dial 524 rotates 120 degrees, transporting the bottle caps 6 within the transmission slot 525 to an input point near either the first or second output track 523, the other transmission slot 525 is positioned closer to the input end. When the bottle cap 6's opening is downward, the dial 524 is rotated clockwise to the first output track 522; when the bottle cap 6's opening is upward, the dial 524 is rotated counterclockwise to the second output track 523.

[0083] The first output track 522 and the second output track 523 are configured as cam paths, and the protruding portion 526 of the cam path is located at the interface between the transport groove 511 of the dial 524 and the first output track 522 or the second output track 523.

[0084] When the dial 524 rotates toward the corresponding first output rail 522 or second output rail 523, the protrusion 526 on the cam path pushes the bottle cap 6 out of the transmission groove 525 to prevent the dial 524 from getting stuck.

[0085] The orientation component 53 includes:

[0086] A straight slide groove 531 is connected to the first output track 522, and the width of the straight slide groove 531 is adapted to the diameter of the bottle cap 6.

[0087] The spiral tube 532 is provided on the base plate 7 along the length of the base plate 7. The spiral tube 532 is connected to the second output track 523. The spiral tube 532 is provided with a spiral channel 533. The rotation angle of the spiral channel 533 is 180 degrees.

[0088] The straight slide 531 receives correctly oriented bottle caps 6 from the first output track 522, i.e., the opening of the bottle caps 6 faces downwards. The spiral tube 532 receives incorrectly oriented bottle caps 6 from the second output track 523, i.e., the opening of the bottle caps 6 faces upwards. The cross-section of the input opening of the spiral channel 533 is rotated 180 degrees along the length of the spiral tube 532, so that the output opening is 180 degrees reversed from the input opening. Therefore, when the incorrectly oriented bottle caps 6 pass through the spiral tube 532, the incorrectly oriented bottle caps 6 will reverse, so that the bottle caps 6 enter the spiral tube 532 with the opening facing upwards, but leave the spiral tube 532 with the opening facing downwards, so that the openings of the bottle caps 6 that finally enter the outlet plate are all facing downwards.

[0089] The embodiments of this application have been described above with reference to the accompanying drawings. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. This application is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of this application without departing from the spirit and scope of the claims, and all of these forms are within the protection scope of this application.
