Detailed Implementation

[0017] Reference Figures 1 to 4 A multi-head linear capping machine includes an S-shaped bottle conveyor belt 1. Above the S-shaped bottle conveyor belt 1 are a servo screw bottle feeding mechanism 2, a servo fork bottle feeding mechanism 3, a bottle holding mechanism 4, and a detection and rejection device 5. The servo screw bottle feeding mechanism 2 and the servo fork bottle feeding mechanism 3 are connected, and the servo fork bottle feeding mechanism 3 and the bottle holding mechanism 4 correspond to each other. The detection and rejection device 5 is located downstream of the servo fork bottle feeding mechanism 3. A cap lifting machine 6 is arranged beside the S-shaped bottle conveyor belt 1. The cap lifting machine 6 is connected to a toothed ring cap sorter 7. The toothed ring cap sorter 7 is connected to a servo cap separating mechanism 8. The servo cap separating mechanism 8 is connected to a multi-channel cap conveying mechanism 9. The output end of the multi-channel cap conveying mechanism 9 is equipped with a cap blocking mechanism 10 and a cap clamping and feeding mechanism 11. The cap clamping and feeding mechanism 11 corresponds to the servo fork bottle feeding mechanism 3. A capping mechanism 12 is arranged directly above the servo fork bottle feeding mechanism 3.

[0018] During operation, bottles 60 are conveyed by the S-shaped bottle conveyor belt 1 to the servo screw bottle feeding mechanism 2. The servo screw bottle feeding mechanism 2 divides the bottles 60 and delivers them to the corresponding positions of the servo fork bottle feeding mechanism 3. The servo fork bottle feeding mechanism 3 and the servo screw bottle feeding mechanism 2 operate synchronously to convey the bottles 60 to the bottom of the capping mechanism 12. The bottle holding mechanism 4 holds the bottles 60 tightly. At the same time, the cap lifting machine 6 lifts the caps 59 into the toothed ring cap sorter 7 for sorting. The caps then enter the servo cap separating mechanism 8, which conveys the caps 59 to the multi-channel cap conveying mechanism 9. After the cap blocking mechanism 10 blocks the cap 59, the cap clamping and cap feeding mechanism 11 first clamps the cap 59, and then sends the cap 59 to the bottom of the capping mechanism 12. The capping mechanism 12 descends and grabs the cap, while the cap clamping and cap feeding mechanism 11 releases the cap 59. At the same time, the cap clamping and cap feeding mechanism 11 retracts and performs the capping action again. The capping mechanism 12 screws the cap 59 onto the mouth of the bottle 60. The servo fork bottle feeding mechanism 3 and the servo screw bottle feeding mechanism 2 work together to send the capped bottle 60 to the detection and rejection device 5. If a defective product is detected, it is rejected, and the qualified product flows into the next process.

[0019] Reference Figures 2 to 5 The servo cap-splitting mechanism 8 includes a cap-splitting box 13, a cap-splitting motor 14, a cap-splitting lever assembly 15, and a cap-feeding channel 16. The cap-splitting box 13 has multiple cap-splitting channels 17. The cap-splitting motor 14 is located at the bottom of the cap-splitting box 13. The cap-splitting lever assembly 15 is located inside the cap-splitting box 13. The cap-splitting box 13 has a cap-feeding port 18, which is connected to the toothed cap feeder 7 through the cap-feeding channel 16. The cap-feeding port 18 corresponds to the cap-feeding end of the cap-splitting lever assembly 15. The cap-splitting lever assembly 15 is connected to the output shaft of the cap-splitting motor 14. The cap-splitting motor 14 drives the cap-splitting lever assembly 15 to distribute the caps to the cap-splitting channels 17.

[0020] Two arc-shaped limiting holes 19 are provided on the top of the lid box 13.

[0021] The cover-opening lever assembly 15 includes a main lever 20 and a secondary lever 21. The main lever 20 and the secondary lever 21 are parallel to each other and form a cover-opening groove 22. The main lever 20 is connected to the output shaft of the cover-opening motor 14. Two limiting rods 23 are hinged between the main lever 20 and the secondary lever 21. The two limiting rods 23 are located in two arc-shaped limiting holes 19, one-to-one.

[0022] After being sorted by the toothed ring cover sorter 7, the cover 59 enters the cover-separating groove 22 through the cover inlet 18. The cover-separating motor 14 drives the main lever 20 to rotate the secondary lever 21, so that the cover outlet end of the cover-separating groove 22 is aligned with the cover-separating channel 17 in sequence, so that the cover 59 enters the cover-separating channel 17, and then enters the multi-channel cover conveying mechanism 9 through the cover-separating channel 17.

[0023] Reference Figure 6The multi-channel lid conveying mechanism 9 includes a lid conveyor belt 24 and lid conveying guardrails 25. The number of lid conveying guardrails 25 is equal to the number of lid-separating channels 17. Multiple lid conveying guardrails 25 are arranged above the lid conveyor belt 24. The output end of the lid-separating channel 17 is connected to the input end of the lid conveying guardrail 25.

[0024] Reference Figure 7 The cover mechanism 10 includes a support plate 26, a cover plate 27, and a cover cylinder 28. The output end of each cover conveying guardrail 25 is provided with a support plate 26, and the cover plate 27 is located in front of the support plate 26. The drive shafts of the cover plate 27 and the cover cylinder 28 are connected.

[0025] When the lid conveyor 17 transports the lid 59 to the input end of the lid conveyor guardrail 25, the lid 59 enters the bottom of the lid conveyor guardrail 25. Under the action of the lid conveyor belt 24, the lid 59 is transported along the lid conveyor guardrail 25 to the pallet 26. At the same time, the cover blocking cylinder 28 drives the cover blocking plate 27 to move closer to the pallet 26, and the cover blocking plate 27 blocks the lid 59.

[0026] Reference Figure 8 The cap clamping and feeding mechanism 11 includes cap clamping claws 29, cap clamping slide cylinders 30, and cap feeding electric cylinders 31. The cap clamping slide cylinders 30 are double slide cylinders, and the number of cap clamping slide cylinders 30 is equal to the number of cap conveying guardrails 25. Multiple cap clamping slide cylinders 30 are arranged in a straight line at intervals on the cap feeding electric cylinder 31. Each cap clamping slide cylinder 30 is equipped with two cap clamping claws 29 that cooperate with each other to clamp.

[0027] When the cap 59 is blocked by the cover plate 27 at the support plate 26, the cap clamping slide cylinder 30 drives the two cap clamping claws 29 on it to clamp it. The two cap clamping claws 29 clamp the two sides of the cap 59. At the same time, the cover blocking cylinder 28 drives the cover plate 27 to release the cap 59. The cap feeding cylinder 31 drives the cap clamping claws 29 to send the cap 59 directly below the capping mechanism 12. The capping mechanism 12 descends and grips the bottle 60. At this time, the cap clamping slide cylinder 30 drives the two cap clamping claws 29 on it to release the cap 59. The capping mechanism 12 rotates to tighten the cap 59 at the mouth of the bottle 60.

[0028] Reference Figures 9 to 10 The servo fork bottle feeding mechanism 3 includes a dial plate 32, an X-axis electric cylinder 33, and a Y-axis electric cylinder 34. The dial plate 32 is connected to the slide of the X-axis electric cylinder 33, and the X-axis electric cylinder 33 is connected to the slide of the Y-axis electric cylinder 34. The inner side of the dial plate 32 is provided with multiple limiting grooves 35 distributed along the length direction of the dial plate 32.

[0029] The bottle holding mechanism 4 includes bottle holding blocks 36. The number of bottle holding blocks 36 is equal to the number of capping mechanisms 12. The bottle holding blocks 36 correspond to the lever plate 32. The bottle holding blocks 36 can be driven by a cylinder to move closer to or further away from the lever plate 32.

[0030] When bottle 60 is conveyed to the limiting groove 35 of the deflector plate 32, the cylinder drives the bottle holding block 36 to move closer to the deflector plate 32. Through the cooperation of the bottle holding block 36 and the limiting groove 35 of the deflector plate 32, the bottle 60 is held tightly. The capping mechanism 12 screws the cap 59 onto the bottle mouth of bottle 60. After the capping is completed, the cylinder drives the bottle holding block 36 to move away from the deflector plate 32, so that the bottle holding block 36 releases the bottle 60. The X-axis electric cylinder 33 drives the deflector plate 32 to convey the bottle 60 towards the detection and rejection device 5. After being detected by the detection and rejection device 5, the Y-axis electric cylinder 34 drives the deflector plate 32 to move backward, releasing the bottle 60, so that the bottle 60 enters the next process with the S-shaped bottle conveyor belt 1.

[0031] The inspection and rejection device 5 includes a gantry inspection mechanism 37 and a rejection mechanism 38. The bottle 60 is first inspected by the gantry inspection mechanism 37. If it is detected as a defective product, the rejection mechanism 38 will reject the defective product.

[0032] Referring to 6, it also includes a mounting frame 39, a support frame 40, and a sliding cable 41. The mounting frame 39 is positioned above the multi-channel cover conveying mechanism 9. The support frame 40 is positioned on the front side of the mounting frame 39 via a slide rail 42 and a slider. The capping mechanism 12 is positioned on the support frame 40. A limiting seat 43 is provided on the support frame 40. A guide rod 44 is provided on the rear side of the mounting frame 39. A counterweight 45 is movably mounted on the guide rod 44. A guide wheel 46 is provided on the top of the mounting frame 39. The sliding cable 41 is mounted on the guide wheel 46, and one end of the sliding cable 41 is connected to the counterweight 45. The other end of the sliding cable 41 passes through the limiting seat 43 and is connected to the support frame 40.

[0033] The height of the capping mechanism 12 can be adjusted by increasing or decreasing the weight of the counterweight 45. For example, increasing the weight of the counterweight 45 can drive the support frame 40 to rise along the slide rail 42 via the slide cable 41, thereby raising the capping mechanism 12. Reducing the weight of the counterweight 45 can lower the support frame 40 along the slide rail 42, thereby lowering the capping mechanism 12, so that the height of the capping mechanism 12 is adapted to the height of the S-shaped bottle conveyor belt 1.

[0034] The S-shaped bottle conveyor belt 1 includes a main conveyor belt 47, an auxiliary conveyor belt 48, and a limiting frame 49. The main conveyor belt 47 and the auxiliary conveyor belt 48 are arranged in a T-shape. The limiting frame 49 includes a U-shaped frame 50. The U-shaped frame 50 is located directly above the auxiliary conveyor belt 48 and is distributed along the length of the auxiliary conveyor belt 48. The two ends of the U-shaped frame 50 are bent outward to form a feeding section 51 and a discharging section 52. A dividing strip 53 is set in the middle of the interior of the U-shaped frame 50. One end of the dividing strip 53 branches outward to a feeding rod 55, a feeding rod 55, a feeding rod 55, and a discharging rod 56. A feeding channel 57 is formed between the feeding section 51 and the feeding rod 55, and a discharging channel 58 is formed between the discharging section 52 and the discharging rod 56. The feeding channel 57 and the discharging channel 58 are located above the main conveyor belt 47.

[0035] When conveying bottle 60, bottle 60 enters from the input end of main conveyor belt 47, enters secondary conveyor belt 48 through feed channel 57, moves along U-shaped frame 50, and then returns to main conveyor belt 47 through discharge channel 58, and enters servo screw bottle feeding mechanism 2 with main conveyor belt 47.

[0036] In this embodiment, five cap conveying guardrails 25, five cap-separating channels 17, five cap-clamping slide cylinders 30, five bottle-holding blocks 36, and five capping mechanisms 12 are each provided. Five bottles 60 can be capped simultaneously at a time. During capping, multiple bottles 60 are positioned in a straight line within the limiting grooves 35 of the push plate 32. The push plate 32 pushes forward five bottles 60 each time. Because the interval between any two adjacent capping mechanisms 12 is different from the interval between any two adjacent limiting grooves 35, during capping, if... Figure 11 As shown, for example, the bottles 60 located in the limiting groove 35 are numbered 1, 2, 3, 4, 5, 1, 2, 3, 4, 5, and the five capping mechanisms 12 are numbered A, B, C, D, E. When the capping begins, the five capping mechanisms 12 numbered A, B, C, D, E cap the bottles numbered 1, 3, 5, 2, 4. After the capping is completed, the push plate 32 pushes the bottles forward. When the capping is performed again, the five capping mechanisms 12 numbered A, B, C, D, E cap the bottles numbered 2, 4, 1, 3, 5, thus achieving capping of five bottles each time.

[0037] The technical applications and usage instructions for the lid lifting machine 6, the toothed ring lid feeder 7, the cap screwing mechanism 12, the gantry inspection mechanism 37, and the rejection mechanism 38 are very mature and complete, and their related structures will not be described in detail in this article.

[0038] The above detailed description is a specific description of a feasible embodiment of the present utility model. This embodiment is not intended to limit the patent scope of the present utility model. All equivalent implementations or modifications that do not depart from the present utility model should be included in the patent scope of this case.
