[0039] Reference Figure 1-13The capping and feeding device is used to open the bottle cap 110 on the bottle body 100, add the first particulate material into the bottle body 100, and then screw back the bottle cap 110, wherein the bottle cap 110 is threadedly connected to the bottle body 100.

[0040] The capping and feeding device for adding materials includes a main transport mechanism 120 for conveying bottles 100. A workbench 121 is provided on one side of the middle portion of the main transport mechanism 120, on which a turntable mechanism 200 is mounted. The turntable mechanism 200 is used to remove bottles 100 from the main transport mechanism 120 and return them to the main transport mechanism 120.

[0041] The turntable mechanism 200 includes a turntable 210, which is rotatably mounted on a workbench 121. Multiple receiving slots 211 are evenly distributed around the outer periphery of the turntable 210, each of which can accommodate a single bottle 100. Two of the receiving slots 211 are aligned with the transport track of the main transport mechanism 120. The workbench 121 is also equipped with a limiting fence surrounding the outer periphery of the turntable 210 and a drive motor for driving the turntable 210. As the bottles 100 transported by the main transport mechanism 120 pass through the turntable mechanism 200, they enter one of the receiving slots 211 aligned with the transport track of the main transport mechanism 120. As the turntable 210 rotates, the bottles 100 entering the receiving slots 211 are moved onto the workbench 121. The position and movement speed of the bottles 100 are determined by the rotational speed of the turntable 210, thereby facilitating the loading sequence of the bottles 100. After the bottle body 100 is moved to be aligned with the transport track of the main transport mechanism 120 , the bottle body 100 is transported again by the main transport mechanism 120 .

[0042] A capping mechanism 300 is also mounted on the top of the workbench 121, and a first feeding mechanism 400 is provided on one side of the workbench 121. After the bottle body 100 enters one of the receiving slots 211, the capping mechanism 300 unscrews and removes the bottle cap 110 from the top of the bottle body 100. After the first feeding mechanism 400 delivers the first granular material into the bottle body 100, the capping mechanism 300 screws the bottle cap 110 back into the bottle body 100. This allows the bottle body 100 with the cap 110 to be directly fed into the production line, reducing the trouble of sorting the bottle caps 110.

[0043] Reference Figure 1-3Specifically, a bottle unscrambling mechanism 700 is provided at the front end of the main transport mechanism 120. The bottle unscrambling mechanism 700 includes a support frame 710, a third drive motor is mounted on the top of the support frame 710, and a rotating plate 720 is rotatably mounted on the top of the support frame 710. The output end of the third drive motor is connected to the middle of the rotating plate 720, so that the third drive motor can drive the rotating plate 720 to rotate. A surrounding plate 730 is also mounted on the top of the support frame 710. The surrounding plate 730 is arranged around the outer side of the rotating plate 720. The surrounding plate 730 is provided with a first notch and a second notch. The first notch is connected to the front end of the main transport mechanism 120.

[0044] A guide plate 740 is mounted on the top of the support frame 710. An adjustment rod 760 is mounted on the top of the support frame 710. The ends of the adjustment rod 760 are attached to the top of the support frame 710 via two vertical rods, allowing the adjustment rod 760 to span across the top of the rotating plate 720. The adjustment rod 760 is removably attached to two parallel vertical plates 770 via bolts. The guide plate 740 is a flexible steel plate that can be bent into any arc shape. The ends of the guide plate 740 are bolted to the bottom of the two vertical plates 770. It is understood that the position of the two vertical plates 770 on the adjustment rod 760 can be adjusted by removing the bolts, thereby changing the arc size of the guide plate 740 to accommodate rotating plates 720 of different sizes. A vertical plate is mounted on the top of the support frame 710. The vertical plate is located near the edge of the rotating plate 720, forming a guide channel 750 between the vertical plate and the enclosure 730. One end of the guide channel 750 faces the edge of the rotating plate 720 , and the other end faces the first notch of the enclosure 730 .

[0045] When multiple bottles 100 that need to be fed are placed into the rotating plate 720 from the second notch position of the enclosure 730, as the rotating plate 720 rotates, the bottles 100 at the edge will enter the main transport mechanism 120 for transportation through the guide channel 750 in turn, while the bottles 100 that fail to enter the guide channel 750 will hit the side of the curved protrusion of the guide plate 740 and gradually move toward the edge of the rotating plate 720 under the guidance of the guide plate 740. As the rotating plate 720 continues to rotate, they will eventually enter the main transport mechanism 120 for transportation from the guide channel 750 in turn, thereby achieving the effect of sorting the bottles 100 and placing them in the main transport mechanism 120.

[0046] In addition, a receiving platform 122 is placed at the rear end, i.e., the end position, of the main transport mechanism 120. The fed bottles 100 are moved to the receiving platform 122 at the rear end of the main transport mechanism 120, so that the bottles 100 can be collected and carried out to the next packaging process.

[0047] Reference Figure 4-6Furthermore, the capping mechanism 300 includes a fixing assembly 310 and a capping assembly 320. The fixing assembly 310 includes a limiting plate 311 and a first telescopic cylinder 312. The first telescopic cylinder 312 is mounted on the workbench 121, and the limiting plate 311 is mounted on the output end of the first telescopic cylinder 312. The limiting fence on the periphery of the turntable 210 is provided with a third notch for the limiting plate 311 to pass through. The limiting plate 311 is arc-shaped on the side facing the turntable 210. The first telescopic cylinder 312 can drive the limiting plate 311 to pass through the third notch and abut against the outside of the bottle body 100, thereby causing the bottle body 100 to abut against the side wall of the receiving groove 211, that is, the bottle body 100 is clamped between the limiting plate 311 and the side wall of the receiving groove 211, so as to facilitate the operation of unscrewing, removing, or putting back the bottle cap 110 on the top of the bottle body 100.

[0048] The cap screw assembly 320 includes a first lift drive 321 mounted on the workbench 121. A lifting platform 322 is mounted on the output end of the first lift drive 321. The first lift drive 321 can drive the lifting platform 322 to move up and down. A second telescopic cylinder 323 and a first drive motor 324 are mounted on the lifting platform 322. An inner cylinder 325 is rotatably mounted on the output end of the second telescopic cylinder 323. This means that the second telescopic cylinder 323 can drive the inner cylinder 325 to move along its axis. Simultaneously, the inner cylinder 325 can rotate about its axis relative to the output end of the second telescopic cylinder 323. An outer cylinder 326 is mounted on the output end of the first drive motor 324. Three clamping jaws 327 are mounted around the outer cylinder 326. The middle portions of the clamping jaws 327 are rotatably connected to the outer cylinder 326. A connecting rod 328 is rotatably mounted on the outwardly curved tops of the clamping jaws 327. The ends of the connecting rod 328, away from the clamping jaws 327, are rotatably mounted on the inner cylinder 325. The connecting rod 328 and the top of the clamping jaws 327 form an angle of less than 160 degrees. When the output end of the second telescopic cylinder 323 pushes the inner cylinder 325 downward, the bottoms of the multiple clamping jaws 327 are moved closer together under the driving action of the connecting rod 328, so that the multiple clamping jaws 327 can clamp the bottle cap 110. The first drive motor 324 then drives the outer cylinder 326 to rotate, and the outer cylinder 326 drives the clamping jaws 327 and the inner cylinder 325 to rotate relative to the axis of the output end of the third telescopic cylinder 421, thereby rotating the bottle cap 110.

[0049] When the bottle 100 is moved to a preset position, such as below the first lifting drive member 321, by the turntable 210, the turntable 210 stops moving, and the first telescopic cylinder 312 drives the limiting plate 311 to fix the bottle 100. The first lifting drive member 321 drives the lifting platform 322 to descend to a position where the multiple clamping claws 327 surround the outer side of the bottle cap 110. The second telescopic cylinder 323 drives the multiple clamping claws 327 to clamp the bottle cap 110. The bottle cap 110 is then rotated out of the bottle 100 and separated from the bottle 100 by the cooperation of the first drive motor 324 and the first lifting drive member 321. After the first feeding mechanism feeds the first granular material into the bottle 100, the bottle cap 110 is placed back above the bottle 100 and rotated back onto the bottle 100 by the first drive motor 324 and the first lifting drive member 321. Finally, the turntable mechanism 200 returns the bottle cap 110 to the main transport mechanism 120, thereby completing the addition of the first granular material.

[0050] Furthermore, the capping feeding equipment can also include two transverse moving drive members 340. These two transverse moving drive members 340 are jointly provided with a gantry, which is mounted on the top of the workbench 121. The transverse moving drive members 340 include transverse guide rails mounted on the gantry and a pneumatic slider mechanism, which can be driven to slide on the transverse guide rails. There are two fixed assemblies 310 and two capping assemblies 320, each of which is provided with two fixed assemblies 310, respectively, located on either side of the turntable 210. The two first lifting drive members 321 in the two capping assemblies 320 are respectively mounted on the output ends of the two transverse moving drive members 340, namely, the pneumatic slider mechanism.

[0051] When the turntable 210 stops moving the bottles 100, the two fixing assemblies 310 respectively limit the two bottles 100 at intervals. After the first capping assembly 320 unscrews the bottle cap 110 on the first limited bottle 100 at the front end and places it on the turntable 210 through the lateral movement drive 340, the second capping assembly 320 can then take the bottle cap 110 placed on the turntable 210 and rotate the bottle cap 110 back onto the second limited bottle 100 at the rear end (having added the first particulate material). A plurality of positioning cylindrical blocks corresponding to the accommodating grooves 211 can be arranged around the turntable 210. The unscrewed bottle cap 110 can be placed on the positioning cylindrical block to facilitate positioning and placing the bottle cap 110. In addition, the lateral movement drive 340 can adjust the capping position of the capping assembly 320, thereby facilitating adaptation to turntable mechanisms 200 of different sizes.

[0052] Reference Figure 7-8Specifically, the first feeding mechanism 400 includes a material conveyor belt mechanism 410 and a material separation assembly 420. The material conveyor belt mechanism 410 includes a material organizer and a conveyor belt. The material organizer includes a frame and a turntable rotating on the frame. The frame is also equipped with a drive motor for driving the turntable to rotate. The frame is equipped with a guide arc plate, which is located in the middle of the turntable. The frame is also provided with side panels arranged around the outer periphery of the turntable, and the side panels are provided with a fourth notch corresponding to the input end of the conveyor belt. An arc plate is installed on the frame at the top edge of the turntable, and a material channel is formed between the arc plate and the side panel. One end of the material channel corresponds to the position of the fourth notch, and the other end corresponds to the edge of the turntable. The material placed on the turntable will move to the edge of the turntable under the guidance of the guide arc plate, and will be transferred from the material channel to the conveyor belt in sequence. The conveyor belt in this embodiment includes two parallel rollers, a drive motor for driving one of the rollers to rotate, and a flexible endless belt wrapped around the two rollers. The conveyor belt can be used to convey the first particulate material. Side baffles are provided on both sides of the conveyor belt to prevent the first particulate material from falling.

[0053] The end of the conveyor belt corresponds to the upper position of the conveying path of the bottle body 100 and is located between the two screw cap assemblies 320. That is, when the bottle body 100 is unscrewed from the bottle cap 110 and then rotates to the next stop position, the conveyor belt can deliver the first granular material, and the first granular material falls into the bottle body 100 under the action of gravity, thereby realizing the addition of the first granular material.

[0054] The material separation assembly 420 includes a third telescopic cylinder 421 and a fourth telescopic cylinder 423. The third and fourth telescopic cylinders 421 and 423 are arranged side by side, with the telescopic drive directions of the third and fourth telescopic cylinders 421 and 423 being parallel and perpendicular to the conveying direction of the conveyor belt 411. A first partition 422 is mounted on the output end of the third telescopic cylinder 421, and a second partition 424 is mounted on the output end of the fourth telescopic cylinder 423. The first and second partitions 422 and 424 are arranged parallel to each other and separated by a predetermined parallel distance. The conveying direction of the conveyor belt 411 is perpendicular to the first and second partitions 422 and 424.

[0055] The second partition 424 is set to be located at a position close to the conveying end of the conveyor belt 411 relative to the first partition 422 , and the initial positions of the first partition 422 and the second partition 424 are both located at one side of the conveyor belt 411 . After the first granular materials are sequentially transferred to the conveyor belt 411, the fourth telescopic cylinder 423 is first driven to drive the second partition 424 through the side plate to the conveyor belt 411 to intercept the first granular materials on the conveyor belt 411. Then, the third telescopic cylinder 421 is driven to drive the first partition 422 to intercept the first granular materials on the conveyor belt 411, so that there is exactly one first granular material between the first partition 422 and the second partition 424. The fourth telescopic cylinder 423 is driven to drive the second partition 424 away from the conveyor belt 411, so that the separated first granular materials are moved a preset distance on the conveyor belt 411. The fourth telescopic cylinder 423 is then driven to extend the second partition 424 onto the conveyor belt 411. The third telescopic cylinder 421 is then driven to extend the first partition 422 out of the conveyor belt 411, so that the first granular materials collide with the first partition 422. The above steps are repeated, so that the first granular materials can be distributed and conveyed at the preset intervals. This ensures that only one first granular material is placed in each bottle 100 each time.

[0056] Reference Figure 7 Furthermore, a material placement area 412 is provided at the conveying end of the conveyor belt 411. A U-shaped frame is installed at the end of the conveyor belt 411, and the U-shaped frame abuts the end of the conveyor belt 411. The inner space enclosed by the U-shaped frame corresponds to the conveyor belt 411 forming the material placement area 412, so that the first granular material can be intercepted by the U-shaped frame and stay in the material placement area 412.

[0057] The screw-on cap feeding device also includes a gripping mechanism 500. The gripping mechanism 500 includes a second lifting drive member 510. A second drive motor 520 is mounted on the output end of the second lifting drive member 510. The output end of the second drive motor 520 faces downward and is mounted with a crossbar 530. One end of the crossbar 530 is mounted on the output end of the second drive motor 520, and the other end is mounted with a pneumatic flexible claw 540. The pneumatic flexible claw 540 is positioned downward. By driving the second lifting drive member 510, the second drive motor 520, and the pneumatic flexible claw 540, the pneumatic flexible claw 540 can grasp the first granular material in the material placement area 412 and transfer it to the top position of the bottle body 100. The pneumatic flexible claw 540 is then released to place the first granular material into the bottle body 100. This allows the first granular material to be accurately added to the corresponding bottle body 100.

[0058] Further, refer to Figure 1 、 Figure 2 and Figure 7The screw cap feeding equipment also includes a weighing mechanism 600 and a labeling machine 610. The weighing mechanism 600 is arranged on the workbench 121, and the weighing platform of the weighing mechanism 600 corresponds to the conveying end of the conveyor belt 411, that is, the first granular material on the conveyor belt 411 will fall onto the weighing platform for weighing and forming weighing information. The pneumatic flexible claw 540 then grabs the weighed first granular material from the weighing platform and puts it into the bottle body 100. It should be noted that the U-shaped frame needs to be removed at this time. The labeling machine 610 is also installed on the workbench 121 and is located on one side of the conveying end of the main transport mechanism 120. The weighing mechanism 600 and the labeling machine 610 are communicatively connected. The labeling machine 610 can print the weighing information of the first granular material placed in the bottle body 100 on a label, and then affix the label to the bottle body 100.

[0059] In another embodiment, the weighing platform of the weighing mechanism 600 may not be positioned below the conveying end of the conveyor belt 411, but may be located within the movable range of the corresponding pneumatic flexible claw 540, while retaining the U-shaped frame. The pneumatic flexible claw 540 grabs the first granular material from the material placement area 412, places it on the weighing platform for weighing, and then grabs it from the weighing platform and places it into the bottle 100.

[0060] Reference Figure 9-13 In another embodiment, the rotary cap feeding device further includes a cap opening mechanism 800. The cap opening mechanism 800 includes a support base 810 mounted on the workbench 121, and a fifth telescopic cylinder 850 and a limit frame 820 are mounted on the top of the support base 810. A swing frame 830 is slidably mounted on the limit frame 820, and an elastic member 840 is installed between the swing frame 830 and the inner side of the limit frame 820. The elastic member 840 is a coil spring, one end of the coil spring is fixed to the inner side of the limit frame 820, and the other end is fixed to the swing frame 830. The coil spring provides an elastic force to push the swing frame 830 toward the direction of the turntable 210. Two guide round rods are also arranged side by side in the limit frame 820, and both guide round rods are slidably penetrated on the swing frame 830, thereby improving the sliding stability of the swing frame 830.

[0061] The swing frame 830 includes two parallel horizontal slide bars extending toward the turntable 210. A first rotating shaft 831 is slidably mounted on opposite sides of each of the two horizontal slide bars, with the slide bars located away from the turntable 210. The ends of the first rotating shaft 831 are slidably mounted in the slide bars of the two horizontal slide bars. The extension and retraction directions of the fifth telescopic cylinder 850, the sliding direction of the swing frame 830 relative to the limit frame 820, and the sliding direction of the first rotating shaft 831 are all parallel.

[0062] A first rocker arm 832 is rotatably mounted on both ends of the first rotating shaft 831. One end of each first rocker arm 832 is attached to the first rotating shaft 831, and the other ends extend parallel to each other and are rotatably connected to a stopper 834. The stopper 834 is U-shaped, with its ends located on opposite sides of the two first rocker arms 832. A second rocker arm 836 extends parallel to each other on both sides of the stopper arm 834. The ends of the two second rocker arms 836, facing away from the stopper arm 834, are rotatably mounted on the ends of the two transverse slides near the turntable 210. When the first rotating shaft 831 slides within the slide slot, the first rocker arm 832, the second rocker arm 836, and the transverse slide form a triangular shape with a specific relationship.

[0063] A second rotating shaft 833 is mounted in the middle of the two first swing arms 832, rotating together. The two ends of the second rotating shaft 833 are rotatably mounted on the sides of the two first swing arms 832 that are close to each other. A telescopic rod 837 is mounted on both ends of the second rotating shaft 833. The telescopic rod 837 consists of an inner rod and an outer rod that are slidably connected at their respective ends, allowing the telescopic rod 837 to achieve a telescopic function. One end of the telescopic rod 837 is mounted on the second rotating shaft 833, and the other end is rotatably mounted between the two transverse slides of the swing frame 830. The position of the telescopic rod 837 away from one end of the second rotating shaft 833 is between the first rotating shaft 831 and the second swing arm 836. A material table is mounted on the end of the telescopic rod 837 that is close to the second rotating shaft 833. It should be noted that the material table is mounted on the inner or outer rod of the telescopic rod 837, that is, the material table does not affect the telescopic function of the telescopic rod 837. The retaining frame 834 is detachably mounted with a cap clamp 835 via bolts. The cap clamp 835 comprises a top clamping plate and two clamping strips located below the clamping plate on either side. When the cap clamp 835 extends toward the bottle body 100, the two clamping strips are inserted into the bottle body 100 on either side of the bottle mouth, and the clamping plate is located on top of the bottle cap 110, thereby enabling the cap clamp 835 to clamp the bottle cap 110. The first rotating shaft 831 is mounted on the output end of the fifth telescopic cylinder 850, thereby enabling the fifth telescopic cylinder 850 to drive the first rotating shaft 831 to slide.

[0064] When the cover opening mechanism 800 is in the initial state, the fifth telescopic cylinder 850 pulls the first rotating shaft 831 to overcome the elastic force of the coil spring and pulls the swing frame 830 to one side of the limit frame 820. At this time, the swing frame 830 does not extend toward the turntable 210 and does not affect the movement of the bottle body 100 on the turntable 210.

[0065] After the capping mechanism 800 is installed, the capping assembly 320 only needs to unscrew the bottle cap 110 on the bottle body 100, and does not need to remove it. After the gripping mechanism 500 uses the pneumatic flexible claw 540 to clamp the first granular material onto the material table 838, the bottle body 100 with the unscrewed bottle cap 110 is parked at the position corresponding to the turntable 210. Then, by driving the fifth telescopic cylinder 850 to push the first rotating shaft 831, due to the elastic restoring force of the coil spring, the swing frame 830 will move toward the direction of the turntable 210 together with the first rotating shaft 831 until the swing frame 830 hits the other side of the limit frame 820. After the swing frame 830 can no longer move, the two horizontal slide bars of the swing frame 830 are respectively located on both sides of the bottle body 100, and the cap clamp 835 is inserted into and clamps the bottle cap 110. When the fifth telescopic cylinder 850 is driven again to push the first rotating shaft 831 to slide, the first rotating shaft 831 moves relative to the swing frame 830 in the slide groove, pushing the first swing bar 832, the second swing bar 836 and the telescopic rod 837 to swing, so that the bottle cap 110 can be swung outward. In the tilted open state, the material platform tilts as the telescopic rod 837 swings, and the first granular material slides into the bottle body 100 under the action of gravity. The fifth telescopic cylinder 850 is then quickly driven to retract, causing the first rotating shaft 831 to move back relative to the swing frame 830. The first swing arm 832, the second swing arm 836, and the telescopic rod 837 to swing back to their initial positions, allowing the bottle cap 110 to be replaced on the bottle body 100. When the fifth telescopic cylinder 850 is further driven, the first rotating shaft 831 drives the swing frame 830 due to the restriction of the end wall of the chute, overcoming the elastic force of the coil spring and continuing to move, thereby moving the swing frame 830 out of the range of the bottle body 100. The cap clamp 835 pulls off the bottle cap 110 to facilitate the loading of the next bottle body 100. After the bottle body 100 with the first granular material is added, it is moved to the next position by the turntable mechanism 200, and the bottle cap 110 is then screwed on by the capping mechanism 300. It should be noted that after the bottle cap 110 is unscrewed, supported by the screw thread, there is a certain overlap between the bottom of the bottle cap 110 and the bottle mouth of the bottle body 100, so that the cap clip 835 can be smoothly detached from the bottle cap 110.

[0066] The opening mechanism 800 can put the first granular material into the bottle body 100 and quickly put on the bottle cap 110 when the bottle cap 110 is opened to a small opening. The action of opening the bottle cap 110 and the action of putting in the first granular material cooperate with each other to improve the efficiency of putting in the first granular material. At the same time, it reduces the contamination of the inner wall of the bottle body 100 and other materials inside. If the bottle body 100 originally contains liquid material, the bottle cap 110 is promptly covered after the first granular material is put in to prevent the liquid material from splashing.

[0067] In an embodiment without the grabbing mechanism 500, the end of the conveyor belt 411 in the first feeding mechanism 400 can be positioned above the material platform 838, allowing the first granular material on the conveyor belt 411 to fall onto the material platform 838. Furthermore, in an embodiment with the lid opening mechanism 800, the weighing mechanism 600 can be integrated into the material platform 838.

[0068] The embodiment of the present application also provides a screw-cap feeding method for material addition, which uses the above-mentioned screw-cap feeding equipment to open the bottle cap 110 on the bottle body 100, add the first particulate material into the bottle body 100, and then screw the bottle cap 110 back on.

[0069] Specifically, the capping and feeding method includes the following steps:

[0070] The bottle bodies 100 are sequentially and side by side sent to the main transport mechanism 120 by the bottle unscrambling mechanism 700, and the bottle bodies 100 are transported to the turntable mechanism 200 by the main transport mechanism 120, so that the bottle bodies 100 are respectively embedded in the receiving grooves 211 of the turntable 210 and rotate with the rotation of the turntable 210, and then the bottle caps 110 on the turntable 210 are unscrewed by the capping mechanism 300; on the other hand, after the first feeding mechanism 400 sends the first granular material to the material placement area, the grabbing mechanism 500 takes the second granular material. A granular material is transferred to the top of the material table 838, and the weighing mechanism 600 integrated in the material table 838 weighs the first granular material, and generates information to be sent to the labeling machine. The first granular material is quickly put into the bottle body 100 through the opening mechanism 800, and then the bottle cap 110 is tightened by the screwing mechanism 300. The turntable mechanism 200 returns the bottle body 100 with the first granular material added to it to the main transport mechanism 120, and the main transport mechanism 120 sends it to the next packaging process or collection process.

[0071] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the scope of knowledge possessed by ordinary technicians in the technical field without departing from the scope of the present invention.
