Description

Technical Field

[0001] The invention relates to the field of bottle cap arrangement and conveying, and in particular to a bottle cap directional arrangement and conveying device. Background Art

[0002] At present, the commonly used liquid containers in life, such as cooking oil bottles, soy sauce bottles, etc., usually have eccentric liquid outlets in their bottle caps to facilitate smoother pouring of liquids. In the existing automatic cap sorting devices, only cylindrical ordinary bottle caps are usually sorted on the front and back. Although there are certain sorting methods for special-shaped bottle caps, such as photoelectric control, visual recognition, etc., there are still great limitations.

[0003] For related technologies, reference may be made to a Chinese patent with announcement number CN112875253B, which discloses a special-shaped cap sorting machine, comprising a first conveyor belt, a second conveyor belt, a slide plate, a flip-cap slide, a photoelectric sensor and an air nozzle; the special-shaped cap sorting machine detects the state of the bottle caps on the first conveyor belt using a photoelectric sensor, and the air nozzle then blows the bottle caps with the reverse side facing up detected by the photoelectric sensor into the inside of the flip-cap slide, and the bottle caps then flip over to a front-facing posture inside the arc-shaped flip-cap slide and slide onto the second conveyor belt, and the bottle caps with the front-facing side facing up on the first conveyor belt fall onto the second conveyor belt through the slide plate to achieve the convergence of the bottle caps, and the second conveyor belt then conveys the sorted bottle caps out.

[0004] A Chinese patent with announcement number CN106081337B discloses an environmentally friendly bottle cap, including a snap cap, a cap body and a funnel structure arranged in the cap body, the funnel structure including a septum and a liquid outlet and an exhaust port arranged on the septum, the septum is provided with a first-level annular funnel groove, a second-level funnel groove, a third-level one-way funnel groove, a fourth-level funnel groove and a fifth-level funnel groove in sequence from top to bottom; a conical sealing column is provided above the exhaust port; and an air guide hole seat is provided around the exhaust port below the lowest position of the fifth-level funnel groove.

[0005] With respect to the above-mentioned related technologies, liquid containers used in daily life are usually provided with handles. At this time, the assembly requirements of the bottle cap and the bottle require that the direction of the bottle cap be adjusted so that the liquid outlet and the handle are at opposite ends. Otherwise, it is inconvenient for the user to pour the liquid, and the liquid container also becomes a defective product. At the same time, during the process of capping and pressing, the bottle cap needs to be tilted to facilitate the docking of the bottle cap with the bottle mouth of the moving bottle, and the air guide hole seat protrudes from the bottom end surface of the bottle cap. At this time, only when the air guide hole seat is at the highest point of the bottom end surface of the tilted bottle cap can the possibility of the air guide hole seat scraping down the bottle be minimized during the docking process between the bottle cap and the bottle mouth.

[0006] Therefore, it is difficult for the current automatic capping machine to perform directional adjustment on the bottle cap with an eccentric liquid outlet design to ensure that the liquid outlet and the handle are at opposite ends, and to adjust the air guide hole seat to the highest point of the bottom end surface of the inclined bottle cap. Therefore, for the assembled products of such bottle caps and bottles, there is a defect of a high defective rate, and if the air guide hole seat scrapes the bottle down, the liquid in the bottle will spill, which has the potential risk of polluting the production equipment and has the adverse effect of wasting resources. Summary of the invention

[0007] In order to solve the above problems, the present application provides a bottle cap directional sorting and conveying device.

[0008] The present application provides a bottle cap directional sorting and conveying device, which adopts the following technical solution:

[0009] A bottle cap directional sorting and conveying device comprises: a vibrating cap sorting plate, which is used to sort the bottle caps to make the front and back directions consistent, and send the bottle caps out one by one from the discharge end of the vibrating cap sorting plate; and a directional sorting slide, which is integrally connected with the discharge end of the vibrating cap sorting plate, and is used to continue to convey the bottle caps sent out from the discharge end of the vibrating cap sorting plate, and the directional sorting slide is provided with a directional sorting member for adjusting the air guide holes of all the bottle caps to the same side; a direction adjustment sorting slide, which is integrally connected with the discharge end of the directional sorting slide, and is used to continue to convey the bottle caps sent out from the discharge end of the directional sorting slide, and the direction adjustment sorting slide is arranged along its length. The direction spiral is twisted 90 degrees, and is used to adjust the conveyed bottle caps to a vertical state. The direction adjustment and sorting slide is provided with a support for holding the air guide hole seat, and is used to make the far air guide hole seat side of all bottle caps droop naturally due to gravity; the upper cover slide, the upper cover slide is in a single arc shape from top to bottom, and the top of the upper cover slide is vertically connected with the end of the direction adjustment and sorting slide, and is used to convey the oriented and adjusted bottle caps to the capping place, the upper cover slide is provided with an upper cover guide groove consistent with the direction of the upper cover slide, the upper cover guide groove is used for the air guide hole seat to extend out of the upper cover slide, and the upper cover guide groove is located at the center line of the upper cover slide.

[0010] By adopting the above technical solution, the bottle caps are put into the vibrating cap sorting plate in batches. Under the action of the vibrating cap sorting plate, the bottle caps are sorted in the same positive and negative directions and enter the directional sorting slide one by one. After the bottle caps enter the directional sorting slide, the air guide hole seat is adjusted to the same side under the action of the directional sorting member, thereby driving the bottle caps to be oriented and enter the direction adjustment sorting slide. Under the action of the 90-degree spiral twist of the direction adjustment sorting slide, the bottle caps are adjusted from a horizontal state to a vertical state. At the same time, the air guide hole seat is suspended by the support member, and the far air guide hole seat side of all bottle caps naturally droops due to gravity. When the bottle cap is conveyed to the upper cover slideway, the bottle cap slides down along the upper cover slideway due to gravity. At this time, the air guide hole seat is restricted by the upper cover guide groove, so that the bottle cap keeps sliding down in the same direction from beginning to end. When the bottle cap moves to the capping position, the air guide hole seat is at the highest point of the bottom end surface of the inclined bottle cap. At the same time, the bottle cap can also be directional adjusted to meet the requirement that the liquid outlet and the handle are at the opposite side ends, thereby reducing the defective product rate, eliminating production safety hazards, and saving resources.

[0011] Optionally, a support frame is also included, which is located at the lower end of the upper cover slide and is used to support the upper cover slide. A separation gap is provided between the upper cover slide and the adjustment and sorting slide, and the width of the separation gap is smaller than the diameter of the bottle cap air guide hole seat.

[0012] By adopting the above technical solution, the support frame supports the upper cover slide, and vibration is generated when the vibrating plate loading tray is working. The upper cover slide is separated from the direction adjustment and sorting slide by setting a separation seam, thereby preventing the vibrating cover sorting plate from causing the upper cover slide to vibrate, thereby improving the stability of the bottle cap when moving along the upper cover slide.

[0013] Optionally, an air pipe 1 is provided at one end of the adjusting and sorting slide close to the upper cover slide, and the air pipe 1 is inclined from top to bottom along the direction of the adjusting and sorting slide pointing to the upper cover slide. A through opening is provided on the side of the upper cover slide away from the upper cover guide groove, and the through opening is provided along the length direction of the upper cover slide. An air pipe 2 is fixedly provided on the upper cover slide along the length direction of the through opening, and an exhaust port is provided on the air pipe 2 which is opposite to the through opening. An air source component is provided under the vibrating cover sorting plate, and the air source component is used to transport airflow to the air pipes 1 and 2.

[0014] By adopting the above technical scheme, the air source component conveys air into the air pipe one and the air pipe two when working, and the air pipe one and the air pipe two guide the air flow. After the air flow is ejected from the air pipe one, it pushes the bottle cap to move from the adjustment and sorting slide to the upper cover slide. The air flow in the air pipe two flows along the exhaust port to the through port, and after passing through the through port, it contacts the bottle cap and pushes the bottle cap to move along the upper cover slide, which is beneficial to reduce the probability of the bottle cap getting stuck in the upper cover slide.

[0015] Optionally, the upper cover slide is further provided with a telescopic portion, which is telescopically arranged in the vertical direction for adjusting the vertical height of the upper cover slide, and the telescopic portion is provided with a straight groove corresponding to the upper cover guide groove.

[0016] By adopting the above technical solution, the vertical length of the telescopic part can be adjusted, thereby adjusting the vertical height of the lower end of the upper cover slide, so as to be suitable for bottles of different heights. When the bottle cap passes through the telescopic part, the air guide hole seat moves along the straight groove, and the telescopic part avoids the air guide hole seat through the straight groove.

[0017] Optionally, two adjustment plates are provided at one end of the upper cover slide away from the adjustment and sorting slide, the two adjustment plates are respectively located on both sides of the upper cover guide groove and are parallel to the upper cover guide groove, the adjustment plates are slidably connected to the upper cover slide along the direction approaching or away from the upper cover guide groove, the upper cover slide is provided with a positioning piece for fixing the adjustment plate, and an inclined portion is fixedly provided on the upper end of the adjustment plate, and the inclined portion is inclined in the direction gradually away from the upper cover guide groove along the direction in which the adjustment plate points to the adjustment and sorting slide.

[0018] By adopting the above technical solution, the distance between the two adjustment plates can be adjusted, and the upper cover slide positions the adjustment plate through the positioning piece. When the bottle cap moves to the lower end of the upper cover slide, the air guide hole seat is guided by the inclined portion so that the air guide hole seat enters between the two adjustment plates along the inclined portion, and then the air guide hole seat is adjusted for the second time, which is beneficial to further improve the positioning accuracy of the air guide hole seat.

[0019] Optionally, two elastic plates are provided at one end of the upper cover slide away from the adjusting and arranging slide, and the two elastic plates are respectively located on both sides of the upper cover slide along the width direction, and the two elastic plates gradually approach each other in the direction away from the upper cover slide. An opening is provided at one end of the upper cover slide away from the adjusting and arranging slide, and the opening is located on the side of the upper cover slide away from the upper cover slide. A pressure plate is provided at the opening, and the pressure plate is hinged to the upper cover slide along the vertical direction. An elastic member is provided between the pressure plate and the upper cover slide, and the elastic member is used to push the pressure plate to contact the elastic plate.

[0020] By adopting the above technical scheme, when the bottle cap moves to the lower end of the upper cover slide, the elastic plate and the pressing plate cooperate to limit the bottle cap. At this time, the bottle cap is stationary and in an inclined state. When placing the bottle, the bottle mouth part is made to face the lower end of the inclined bottle cap, and the bottle is made to be on the side of the bottle cap where the air guide hole seat is set. The bottle is pushed toward the bottle cap in the horizontal direction, and the bottle contacts the bottle cap and drives the pressing plate to flip. At this time, the elastic member is deformed, and after the bottle cap and the pressing plate are separated, the pressing plate is reset under the action of the elastic member. At this time, the bottle cap is upside down on the bottle, completing the preliminary assembly of the bottle cap and the bottle.

[0021] Optionally, the upper cover slide is provided with a push rod, one end of which faces the pressure plate and is located on the side of the pressure plate close to the upper cover guide groove. The elastic member pushes the pressure plate to contact the push rod in a natural state. A threaded rod is coaxially fixed to the push rod, and the upper cover slide is provided with a support block adapted to the threaded rod. The threaded rod passes through the support block and is threadedly connected to the support block.

[0022] By adopting the above technical solution, when the threaded rod is rotated, the threaded rod drives the push rod to move under the action of the support block, thereby facilitating the adjustment of the position of the push rod. The push rod limits the pressure plate. When the position of the push rod is different, the distance between the pressure plate and the inner wall of the upper cover slide is pressed differently, making it easy for the pressure plate to limit bottle caps of different thicknesses.

[0023] Optionally, the vibrating cap sorting plate is provided with a feeding device, which extends from bottom to top toward the upper end of the vibrating cap sorting plate, and a raw material bin for storing bottle caps is fixedly provided at the lower end of the feeding device. The feeding device is provided with a circulating conveyor belt along the length direction, and the circulating conveyor belt drives the bottle caps in the raw material bin to move toward the vibrating cap sorting plate when working.

[0024] By adopting the above technical solution, the loading device provides support for the circulating conveyor belt and the raw material bin. The cooperation between the circulating conveyor belt and the raw material bin is conducive to improving the convenience of conveying bottle caps to the vibrating cap sorting tray.

[0025] Optionally, it also includes a frame and a pressure rod, the frame is arranged on one side of the vibrating cover sorting plate, the pressure rod is vertically slidably connected to the frame, the frame is provided with a power part for driving the pressure rod to move, the lower end of the frame is provided with a horizontal conveyor belt for conveying bottles, the horizontal conveyor belt is located directly below the discharge end of the upper cover slide, the upper cover slide and the pressure rod are arranged in sequence along the conveying direction of the horizontal conveyor belt, and the frame is provided with limit rods on both sides along the width direction of the horizontal conveyor belt, and the bottle passes through between the two limit rods when moving.

[0026] By adopting the above technical solution, the frame is used to support the horizontal conveyor belt and the pressure rod. After the bottle is placed on the horizontal conveyor belt, the horizontal conveyor belt drives the bottle to move toward the upper cover slide, and the limit rod limits the bottle, which is beneficial to reduce the probability of the bottle being offset during movement. After the bottle cap is moved out of the upper cover slide and inverted on the top of the bottle, the bottle and the bottle cap are driven by the horizontal conveyor belt to move under the pressure rod. At this time, the pressure rod is driven downward by the power piece to press the bottle cap tightly, thereby completing the press-fitting of the bottle cap and the bottle.

[0027] Optionally, a pressing plate is provided at the lower end of the pressure rod, and an elastic block is fixedly provided on the side of the pressing plate facing away from the pressure rod. The pressing plate is slidably connected to the pressure rod along the conveying direction of the horizontal conveyor belt, and a reset member is provided between the pressure rod and the pressing plate. When the pressing plate and the pressure rod produce relative displacement, the reset member is used to drive the pressing plate to reset.

[0028] By adopting the above technical solution, when the pressure rod moves, it drives the pressing plate and the elastic block to move. The elastic block is used to contact the bottle cap and press the bottle cap. When the bottle cap contacts the elastic block, the horizontal conveyor belt keeps working. At this time, the bottle continues to move along the horizontal conveyor belt, and the elastic block drives the pressing plate to move horizontally, which helps to reduce the probability of the bottle cap shaking due to the resistance of the pressure rod. After the pressing is completed, when the elastic block is separated from the bottle cap, the reset member drives the pressing plate and the elastic block to reset.

[0029] In summary, the present application includes at least one of the following beneficial technical effects:

[0030] 1.Put the bottle caps in batches into the vibrating cap sorting plate. Under the action of the vibrating cap sorting plate, the bottle caps are sorted in the same positive and negative directions and enter the directional sorting slide one by one. After the bottle caps enter the directional sorting slide, the air guide hole seats are adjusted to the same side under the action of the directional sorting parts, thereby driving the bottle caps to be oriented and enter the direction adjustment sorting slide. Under the action of the 90-degree spiral twist of the direction adjustment sorting slide, the bottle caps are adjusted from a horizontal state to a vertical state. At the same time, the air guide hole seats are suspended by the support members, and the far air guide hole seat sides of all bottle caps naturally droop due to gravity. When the bottle cap is transported to the upper cover slideway, the bottle cap slides down along the upper cover slideway due to gravity. At this time, the air guide hole seat is restricted by the upper cover guide groove, so that the bottle cap keeps sliding in the same direction from beginning to end. When the bottle cap moves to the capping position, the air guide hole seat is at the highest point of the bottom end surface of the inclined bottle cap. At the same time, the bottle cap can also be directional adjusted to meet the requirement that the liquid outlet and the handle are at the opposite side, thereby reducing the defective product rate, eliminating production safety hazards, and saving resources;

[0031] 2. The distance between the two adjustment plates can be adjusted. The upper cover slideway positions the adjustment plate through the positioning piece. When the bottle cap moves to the lower end of the upper cover slideway, the air guide hole seat is guided by the inclined portion so that the air guide hole seat enters between the two adjustment plates along the inclined portion, and then the air guide hole seat is adjusted for the second time, which is beneficial to further improve the positioning accuracy of the air guide hole seat.

DETAILED DESCRIPTION

[0039] The present application is further described in detail below in conjunction with all the accompanying drawings.

[0040] The embodiment of the present application discloses a bottle cap directional sorting and conveying device.

[0041] Reference Figure 1 and Figure 2 A bottle cap directional sorting and conveying device comprises a vibrating cap sorting plate 1, a directional sorting slide 2, a direction adjustment sorting slide 3 and a capping slide 4. The vibrating cap sorting plate 1 comprises a hopper for placing bottle caps 100 and a feeding track arranged in a spiral along the circumference of the hopper. A vibration motor is arranged at the lower end of the hopper. When the vibration motor vibrates, it drives the bottle caps 100 in the hopper to rise in a spiral along the feeding track. When the bottle caps 100 move along the feeding track, the feeding track screens the bottle caps 100 so that the positive and negative directions of all the bottle caps 100 moved to the discharge end of the feeding track are consistent. At this time, the side of the bottle cap 100 provided with the air guide hole seat 102 faces upward. The vibrating cap sorting plate 1 is a prior art and will not be described in detail here.

[0042] Reference Figure 1 and Figure 2A feeding device 11 is also installed on one side of the vibrating cap sorting plate 1. The feeding device 11 is inclined from bottom to top, from the outer circle of the vibrating cap sorting plate 1 to the center of the circle, and the upper end of the feeding device 11 is located above the vibrating cap sorting plate 1. A raw material bin 12 is installed at the lower end of the feeding device 11. The raw material bin 12 is used to place bottle caps 100 in batches. The feeding device 11 is provided with a circulating conveyor belt 13 along the length direction. When the circulating conveyor belt 13 is working, it drives the bottle caps 100 in the raw material bin 12 to continuously move toward the vibrating cap sorting plate 1. A discharge port is fixed at the upper end of the feeding device 11. After the bottle caps 100 are moved to the upper end of the feeding device 11 driven by the circulating conveyor belt 13, they are separated from the circulating conveyor belt 13. At this time, the bottle caps 100 fall into the vibrating cap sorting plate 1 along the discharge port, which is conducive to improving the convenience of placing the bottle caps 100 into the vibrating cap sorting plate 1.

[0043] Reference Figure 2 and Figure 3 The directional sorting slide 2 is fixedly arranged at the upper end of the hopper and spirals upward along the circumference of the hopper. The directional sorting slide 2 is hollow, and the height of the inner diameter of the directional sorting slide 2 is greater than the thickness of the bottle cap 100, and the width of the inner diameter of the directional sorting slide 2 is greater than the diameter of the bottle cap 100. One end of the directional sorting slide 2 is connected to the feeding rail, and the bottle caps 100 moving along the feeding rail enter the directional sorting slide 2 one by one.

[0044] Reference Figure 4 It should be noted that the bottle cap 100 in this embodiment includes a cover body for connecting a bottle 110 and a buckle cover that is snap-fitted to the cover body. The cover body is provided with a liquid outlet 101 along the axial direction, and is also provided with an air guide hole seat 102 corresponding to the liquid outlet 101. The liquid outlet 101 and the air guide hole seat 102 are far from each other and are both eccentrically arranged relative to the cover body. The air guide hole seat 102 is located on the side of the cover body away from the buckle cover and extends out of the cover body. When the buckle cover is snap-fitted to the cover body, the liquid outlet 101 and the air guide hole seat 102 are blocked.

[0045] Reference Figure 2 and Figure 3 When the bottle caps 100 that have passed through the screening of the feeding track are close to the directional sorting slide 2, the end surface provided with the air guide hole seat 102 faces upward, and the directional sorting slide 2 is provided with a directional sorting member 21 for guiding the bottle caps 100. The directional sorting member 21 includes a guide plate, which is arranged along the length direction of the directional sorting slide 2, and the side of the guide plate away from the hopper is fixedly connected to the directional sorting slide 2. The gap between the side of the guide plate close to the hopper axis and the side wall of the directional sorting slide 2 constitutes a guide groove. After the bottle caps 100 enter the directional sorting slide 2, the corresponding air guide hole seat 102 enters the guide groove. An adjustment port connected to the guide groove is provided at one end of the directional sorting slide 2 close to the feeding track.

[0046] Reference Figure 2 and Figure 4 When the air guide hole seat 102 of the bottle cap 100 is directly opposite to the guide groove, the air guide hole seat 102 and the inner wall of the regulating port do not contact each other, and the air guide hole seat 102 directly passes through the regulating port into the guide groove. When the air guide hole seat 102 of the bottle cap 100 is in a position deviating from the guide groove, the bottle cap 100 drives the air guide hole seat 102 close to the inner wall of the regulating port during movement. After the air guide hole seat 102 contacts the inner wall of the regulating port, the bottle cap 100 continues to move along the directional sorting slide 2. Under the limiting effect of the inner wall of the regulating port on the air guide hole seat 102, the air guide hole seat 102 of the bottle cap 100 enters the guide groove along the inner wall of the regulating port. The guide groove is located on the side of the directional sorting slide 2 close to the hopper, so that the air guide hole seats 102 of all bottle caps 100 moving along the directional sorting slide 2 are in the same direction.

[0047] Reference Figure 2 and Figure 4 The adjustment and sorting slide 3 is fixedly arranged at the end of the directional sorting slide 2 away from the material feeding rail, and the end of the adjustment and sorting slide 3 away from the directional sorting slide 2 is spirally twisted 90 degrees along its own width direction. When the bottle cap 100 enters the adjustment and sorting slide 3 from the directional sorting slide 2, it flips along the twisting direction of the adjustment and sorting slide 3.

[0048] Reference Figure 2 and Figure 4 The direction-adjusting and sorting slide 3 is provided with a support member 31 for supporting the air guide hole seat 102, the support member 31 is connected to the guide plate, and an escape port connected to the guide groove is also reserved between the support member 31 and the direction-adjusting and sorting slide 3. After the bottle cap 100 enters the direction-adjusting and sorting slide 3, its air guide hole seat 102 enters the escape port, and at this time, the support member 31 supports the air guide hole seat 102. Under the action of gravity, when the bottle cap 100 moves along the direction-adjusting and sorting slide 3, the side away from the air guide hole seat 102 is in a drooping state, so that the air guide hole seats 102 of all the bottle caps 100 moved to the discharging end of the direction-adjusting and sorting slide 3 are in a relatively upper position, thereby realizing automatic sorting of the bottle caps 100.

[0049] Reference Figure 2 and Figure 3 The cover slide 4 is located at one end of the adjustment and sorting slide 3 away from the directional sorting slide 2, and the bottle cap 100 (reference Figure 4 ) gradually approaches the upper cover slide 4 under the action of the vibrating cover sorting plate 1. A support frame 5 is provided at the lower end of the upper cover slide 4, and a support rod is fixed at the upper end of the support frame 5, and the support rod is used to support the upper cover slide 4. A separation gap is provided between the upper cover slide 4 and the direction adjustment and sorting slide 3, so that the upper cover slide 4 and the direction adjustment and sorting slide 3 are separated. When the vibrating cover sorting plate 1 vibrates, the upper cover slide 4 is in a stationary state.

[0050] Reference Figure 2 and Figure 3 The vibrating cap sorting plate 1 is provided with a pushing member for pushing the bottle caps 100 to move, and the pushing member includes an air pipe 1 61, an air pipe 2 62 and an air source member 63. The air pipe 1 61 is fixedly connected to the direction adjustment and sorting slide 3 and is located on the side of the direction adjustment and sorting slide 3 close to the cover slide 4. One end of the air pipe 1 61 is directly opposite to the guide groove, and is inclined from the upper guide along the direction of the direction adjustment and sorting slide 3 pointing to the cover slide 4.

[0051] Reference Figure 2 and Figure 4 The upper cover slideway 4 is hollow, and a side thereof close to the support member 31 is provided with an upper cover guide groove 41 along the length direction. When the air guide hole seat 102 is directly opposite to the upper cover guide groove 41, the bottle cap 100 drives the air guide hole seat 102 to move along the upper cover guide groove 41 under the action of gravity. The upper cover guide groove 41 is located in the middle of the upper cover slideway 4, and the width of the upper cover guide groove 41 matches the width of the bottle cap 100. When the bottle cap 100 moves along the upper cover slideway 4, its air guide hole seat 102 is located in the upper cover guide groove 41.

[0052] Reference Figure 2 and Figure 4 The second air pipe 62 is arranged along the length direction of the upper cover slide 4, the upper cover slide 4 is fixedly connected to the second air pipe 62, and the second air pipe 62 is provided with a plurality of exhaust ports 621 along the length direction, all of the exhaust ports 621 are located on the side of the second air pipe 62 close to the upper cover slide 4, and the exhaust ports 621 are arranged along the upper cover slide 4 away from the direction of the adjustment and finishing slide 3, and are inclined from the axis of the second air pipe 62 to the outer edge.

[0053] Reference Figure 2 and Figure 3 The upper cover slide 4 has a through hole 42 opened along the length direction on one side near the air pipe 2 62, and the through hole 42 is directly opposite to the exhaust port 621. The air source component 63 is installed at the lower end of the vibrating cover sorting plate 1, and is used to deliver air to the air pipe 1 61 and the air pipe 2 62. The air source component 63 can be a fan or a gas cylinder. In this embodiment, the air source component 63 is selected as a fan. After the air source component 63 drives the air flow into the air pipe 1 61 and the air pipe 2 62, the air flow flowing along the air pipe 1 61 is discharged from the air pipe 1 61 and flows toward the guide groove, thereby pushing the bottle cap 100 (reference Figure 4 ) enters the upper cover slide 4, which is conducive to lowering the bottle cap 100 (reference Figure 4 ) The probability of getting stuck at the connection between the adjustment and sorting slideway 3 and the upper cover slideway 4. The airflow flowing along the air pipe 2 62 is discharged from the exhaust port 621, passes through the through port 42, and enters the upper cover slideway 4, thereby driving the bottle cap 100 in the upper cover slideway 4 (refer to Figure 4 ) moves in the preset direction, lowering the bottle cap 100 (reference Figure 4 ) is stuck in the upper cover slide 4.

[0054] Reference Figure 2 and Figure 4 , the cover slide 4 turns over along its own length direction, and the bending direction is the same as the bending direction of the adjustment and finishing slide 3. After the bottle cap 100 enters the cover slide 4, it turns in the flipping direction of the cover slide 4. When the bottle cap 100 moves to the lower end of the cover slide 4, the side of the bottle cap 100 provided with the air guide hole seat 102 faces downward. The lower end of the cover slide 4 is arranged along a straight line, and is inclined from top to bottom along the bending direction of the cover slide 4. The bottle cap 100 at the lower end of the cover slide 4 is inclined with the cover slide 4, and at this time, the side of the bottle cap 100 provided with the air guide hole seat 102 is in an upper position.

[0055] Reference Figure 2 and Figure 5 Two elastic plates 45 are fixedly arranged at the lower end of the upper cover slide 4. The two elastic plates 45 are respectively located on both sides of the upper cover guide groove 41 along the width direction, and the two elastic plates 45 gradually approach each other in the direction away from the upper cover slide 4. The distance between the closest ends of the two elastic plates 45 is smaller than the diameter of the bottle cap 100 (reference figure), and then when the bottle cap 100 (reference figure) moves along the upper cover slide 4 to between the two elastic plates 45, the two elastic plates 45 cooperate to limit the bottle cap 100 (reference figure) and prevent the bottle cap 100 (reference figure) from falling from the upper cover slide 4.

[0056] Reference Figure 2 and Figure 5 A pressing plate 461 is also provided at the lower end of the upper cover slide 4. The pressing plate 461 is located on one side of the upper cover slide 4 where the through opening 42 is provided. The upper cover slide 4 is provided with an opening adapted to the pressing plate 461. The pressing plate 461 is located in the opening and is vertically hinged to the upper cover slide 4. An elastic member 462 is provided between the pressing plate 461 and the upper cover slide 4. The elastic member 462 is a torsion spring. One end of the torsion spring is fixedly connected to the pressing plate 461, and the other end is fixedly connected to the upper cover slide 4. The torsion spring is in a deformed state, and applies a thrust to the pressing plate 461 to approach the elastic plate 45.

[0057] Reference Figure 2 and Figure 5 , the upper cover slide 4 is provided with a push rod 47 corresponding to the pressure plate 461, and one end of the push rod 47 along the length direction points to the side of the pressure plate 461 close to the upper cover slide 4. A threaded rod 471 is coaxially fixed on the side of the push rod 47 away from the pressure plate 461, and the upper cover slide 4 is fixed with a support block 472 adapted to the threaded rod 471, and the threaded rod 471 passes through the support block 472 and is threadedly connected to the support block 472. The upper cover slide 4 limits the push rod 47 through the cooperation of the support block 472 and the threaded rod 471. In the initial state, the end of the push rod 47 away from the threaded rod 471 contacts the pressure plate 461, thereby positioning the pressure plate 461. The distance between the hinge between the pressure plate 461 and the upper cover slide 4 and the upper cover slide 4 is greater than the bottle cap 100 (reference Figure 4) thickness, under the action of the elastic member 462 and the top rod 47, the distance between the end of the pressing plate 461 away from the hinge and the upper cover slideway 4 is less than the bottle cap 100 (reference Figure 4 ) thickness, at this time, the pressing plate 461 and the elastic plate 45 cooperate to press the bottle cap 100 (reference Figure 4 By adjusting the position of the push rod 47, the initial state of the pressing plate 461 is adjusted so that the pressing plate 461 is suitable for bottle caps 100 of different thicknesses (refer to Figure 4 ) limit.

[0058] Reference Figure 2 and Figure 3 The upper cover slideway 4 is provided with a telescopic portion 43 at the middle position along the length direction. The telescopic portion 43 is arranged to be telescopically arranged in the vertical direction. The upper cover slideway 4 is divided into an upper half track and a lower half track at the center of the telescopic portion 43. The upper half track is located at the upper end of the telescopic portion 43, and the lower half track is located at the lower end of the telescopic portion 43. The telescopic portion 43 is sleeved on the outer side of the upper half track and the lower half track, and the two are slidably connected along the length direction. The telescopic portion 43 is provided with a straight groove 431 adapted to the upper cover guide groove 41. When the bottle cap 100 passes through the telescopic portion 43, its air guide hole seat 102 moves along the straight groove 431.

[0059] Reference Figure 2 and Figure 3 A fixing plate is fixedly arranged near the telescopic part 43 of the upper half rail and the lower half rail, and the fixing plate extends along the length direction of the telescopic part 43. The fixing plate is provided with fixing bolts along the length direction, and the fixing bolts pass through the fixing plate and are threadedly connected with the telescopic part 43. The fixing plate cooperates with the fixing bolts to realize the connection between the upper half rail and the lower half rail and the telescopic part 43. By moving the upper half rail or the lower half rail along the length direction of the telescopic part 43, the vertical height of the lower end of the upper cover slide 4 can be adjusted.

[0060] Reference Figure 2 and Figure 5 , two adjustment plates 44 are also provided at the lower end of the upper cover slide 4. The adjustment plates 44 are located on the side of the upper cover slide 4 away from the through-port 42. The two adjustment plates 44 are respectively located on both sides of the upper cover guide groove 41, and are slidably connected with the upper cover slide 4 in the direction close to or away from the upper cover guide groove 41. An inclined portion 441 is fixedly provided at one end of the adjustment plate 44 close to the adjustment and sorting slide 3, and the inclined portion 441 is driven to move when the adjustment plate 44 moves. In order to reduce the friction force on the air guide hole seat 102 (reference figure) in the upper cover guide groove 41, the width of the upper cover guide groove 41 needs to be greater than the diameter of the air guide hole seat 102 (reference figure) to reduce the collision between the air guide hole seat 102 (reference figure) and the inner wall of the upper cover guide groove 41.

[0061] Reference Figure 4 and Figure 5, the adjusting plate 44 is moved toward the direction close to the upper cover guide groove 41, so that the distance between the two adjusting plates 44 is adapted to the diameter of the air guide hole seat 102, and the upper cover slideway 4 is provided with a positioning member 442 adapted to the adjusting plate 44, and the positioning member 442 is a positioning screw, which passes through the adjusting plate 44 and is threadedly connected to the upper cover slideway 4, thereby fixing the adjusting plate 44. The air guide hole seat 102 of the bottle cap 100 moves between the two adjusting plates 44 along the upper cover guide groove 41, and the adjusting plate 44 guides the air guide hole seat 102 through the inclined portion 441, so that the air guide hole seat 102 enters between the two adjusting plates 44. At this time, the bottle cap 100 contacts the elastic plate 45 and the pressing plate 461, so it is in an inclined static state, and the air guide hole seat 102 of the bottle cap 100 is at the upper end of the bottle cap 100, and the air guide hole seat 102 is adjusted twice by the adjusting plate 44 to improve the positioning accuracy of the bottle cap 100.

[0062] Reference Figure 1 and Figure 6 The directional sorting and conveying device further comprises a frame 7 and a pressure rod 71. The frame 7 is located at one side of the vibrating cover sorting plate 1, and a horizontal conveyor belt 73 is installed at the lower end of the frame 7 along the length direction. The horizontal conveyor belt 73 is located directly below the lower end of the upper cover slide 4. When the bottle 110 is placed on the horizontal conveyor belt 73, the horizontal conveyor belt 73 drives the bottle 110 to move toward the lower end of the upper cover slide 4. The conveying direction of the horizontal conveyor belt 73 is consistent with the bending direction of the upper cover slide 4, and the upper end of the bottle 110 corresponds to the bottle cap 100 at the lowest end of the upper cover slide 4.

[0063] Reference Figure 1 and Figure 6 When the bottle 110 moves from the lower end of the upper cover slide 4, its upper end contacts the side of the bottle cap 100 close to the liquid outlet 101, and the bottle cap 100 pushes the pressing plate 461 away from the push rod 47, at which time the torsion spring and the elastic plate 45 are gradually deformed. When the bottle 110 continues to move, the bottle cap 100 rotates in the horizontal direction under the blocking effect of the pressing plate 461, thereby driving the air guide hole seat 102 to be inserted into the bottle 110, thereby completing the preliminary assembly of the bottle cap 100 and the bottle 110.

[0064] Reference Figure 1 and Figure 4When the bottle 110 is close to the bottle cap 100, the air guide hole seat 102 is located above the bottle cap 100, which is conducive to reducing the probability of collision between the air guide hole seat 102 and the bottle 110. The bottle 110 mentioned in this embodiment has a limitation on the installation angle of the bottle cap 100. For example, when the bottle 110 is installed with a fixed handle 111, the liquid outlet 101 of the bottle cap 100 needs to be located away from the handle 111. When the bottle 110 moves along the horizontal conveyor belt 73, the bottle 110 is oriented and placed so that the handle 111 is located on the side of the bottle 110 away from the liquid outlet 101 of the bottle cap 100, and then when the preliminary assembly is completed, it is ensured that the liquid outlet 101 of the bottle cap 100 is away from the handle 111 of the bottle 110. The frame 7 is provided with limit rods 74 on both sides of the horizontal conveyor belt 73. When the bottle 110 moves along the horizontal conveyor belt 73, the limit rods 74 limit the bottle 110 to prevent the bottle 110 from shaking during the movement.

[0065] Reference Figure 1 and Figure 6 The pressing rod 71 is located at the upper end of the frame 7 and is slidably connected with the frame 7 in the vertical direction. The pressing rod 71 and the upper cover slideway 4 are arranged along the conveying direction of the horizontal conveyor belt 73. The bottle cap 100 and the bottle 110 are initially assembled and move toward the lower end of the pressing rod 71. The frame 7 is equipped with a power member 72 for driving the pressing rod 71 to move vertically. The power member 72 is a cylinder. The cylinder is installed at the upper end of the frame 7, and the output end of the cylinder is connected to the pressing rod 71. A pressing plate 711 is provided at the lower end of the pressing rod 71. The pressing plate 711 is slidably connected with the pressing rod 71 along the conveying direction of the horizontal conveyor belt 73. A reset member 713 is provided between the pressing plate 711 and the pressing rod 71. The reset member 713 is a spring. One end of the spring is fixedly connected to the pressing plate 711, and the other end is fixedly connected to the pressing plate 461.

[0066] Reference Figure 1 and Figure 6 , an elastic block 712 is fixedly arranged at the lower end of the pressing plate 711, and the elastic block 712 is made of a flexible material such as rubber or latex. When the bottle 110 drives the bottle cap 100 to move to the lower end of the pressing rod 71, the power member 72 drives the pressing rod 71 to move downward, so that the pressing rod 71 drives the pressing plate 711 and the elastic block 712 to move, and the elastic block 712 contacts the bottle cap 100 and presses the bottle cap 100 against the upper end of the bottle 110, completing the pressing of the bottle 110 and the bottle cap 100. During the pressing of the bottle cap 100, the horizontal conveyor belt 73 remains in a working state, at which time the bottle 110 and the elastic block 712 are relatively displaced in the lateral direction, and the friction between the bottle cap 100 and the elastic block 712 drives the pressing plate 711 to slide, so that the reset member 713 is deformed, which is conducive to reducing the probability of the bottle 110 shaking due to the resistance of the elastic block 712 to the bottle cap 100.

[0067] The working principle of a bottle cap directional sorting and conveying device according to an embodiment of the present application is as follows: the bottle caps 100 are driven to move in sequence along the directional sorting slide 2, the direction adjustment sorting slide 3 and the cover slide 4 by the vibrating cap sorting plate 1. After the bottle caps 100 enter the directional sorting slide 2, the directional sorting slide 2 limits the air guide hole seats 102 of the bottle caps 100 through the directional sorting member 21, so that the air guide hole seats 102 of the bottle caps 100 moving along the directional sorting slide 2 are located on the same side. When the bottle caps 100 move along the direction adjustment sorting slide 3, under the action of the support member 31, the bottle caps 100 are adjusted for a second time by their own gravity, so that while the bottle caps 100 are turned over along the direction adjustment sorting slide 3, the side away from the air guide hole seat 102 naturally droops.

[0068] When the bottle cap 100 enters the upper cover slide 4, the upper cover slide 4 guides and limits the bottle cap 100 through the upper cover guide groove 41. When the bottle cap 100 moves to the lower end of the upper cover slide 4, the side of the bottle cap 100 away from the air guide hole seat 102 is relatively lower, and the bottle 110 is driven to move by the horizontal conveyor belt 73. When the bottle cap 100 contacts the bottle 110, the side of the bottle cap 100 with the liquid outlet 101 first contacts the bottle 110. When the bottle 110 continues to move, under the blocking effect of the pressing plate 461, the bottle cap 100 drives the air guide hole seat 102 to be inserted into the bottle 110, thereby completing the preliminary assembly of the bottle cap 100. Finally, the bottle cap 100 is pressed and installed by the pressing rod 71 to complete the final assembly of the bottle cap 100 and the bottle 110. When assembling the bottle cap 100, it is only necessary to ensure the state of the bottle 110 when moving along the horizontal conveyor belt 73, and there is no need to interfere with the bottle cap 100. When assembling the bottle cap 100, the liquid outlet 101 and the handle 111 of the bottle cap 100 are at the opposite side ends, which is conducive to reducing the defective rate, eliminating production safety hazards, and saving resources.

[0069] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
