Description

Technical Field

[0001] This utility model relates to the field of labeling equipment, and in particular to a synchronous drive device for pressing and conveying materials. Background Technology

[0002] Bottle labeling machines are automated devices primarily used for affixing labels to bottles, widely used in the pharmaceutical, food, cosmetics, and daily chemical industries. The typical operating procedure of existing bottle labeling machines is as follows: a roll of labels is placed on the unwinding reel; the bottle to be labeled is placed on a conveyor belt; the conveyor belt moves the bottle; as it approaches the labeling position, a bottle-separating device evenly separates the bottles; upon reaching the designated labeling position, a drive roller drives the roll of material, separating the label from the backing paper; a peeling plate detaches the label from the backing paper, making it contact with the bottle; and the labeling roller evenly and smoothly applies the label to the bottle. Current labeling machines suffer from poor stability on the conveyor belt when labeling some flat plastic bottles. The bottles are subjected to a pushing force upon release from the bottle-separating device, easily causing them to tip over on the conveyor belt. This requires worker intervention to ensure continuous and stable operation of the labeling machine and needs improvement. Utility Model Content

[0003] To solve the above problems, this utility model proposes a synchronous drive device for pressing and conveying materials.

[0004] The technical solution of this utility model is: a synchronous drive device for pressing and conveying materials, including a belt conveyor mechanism and a bottle pressing mechanism disposed directly above the belt conveyor mechanism. A reduction motor is installed at one end of the belt conveyor mechanism. The reduction motor is a worm gear reduction motor. One end of the output shaft of the reduction motor is connected to the roller shaft of the drive roller of the belt conveyor. The roller shaft and the output shaft are coaxially connected by a coupling. The bottle pressing mechanism includes two bottle pressing side plates arranged side by side and two bottle pressing pulleys installed at both ends of the bottle pressing side plates. A bottle pressing belt is fitted between the two bottle pressing pulleys. The other end of the output shaft is connected to the bottle pressing pulley at one end of the bottle pressing mechanism through a speed change conversion mechanism.

[0005] Preferably, the speed-changing transfer mechanism includes a first belt assembly and a second belt assembly. The first belt pulley is arranged vertically, and the second belt assembly is arranged horizontally. The first belt assembly includes pulley A and pulley B installed between two side-by-side first side plates. Pulley A and pulley B are the same size and have anti-slip ribs. A first belt connects pulley A and pulley B. Pulley A is connected to the output shaft. The second belt assembly includes pulley C and pulley D installed between two side-by-side second side plates. Pulley C and pulley D are the same size. A second belt connects pulley C and pulley D. The second belt has the same width as the first belt. The corresponding pulleys B and C are coaxially connected via a synchronous shaft. Pulley D is connected to the bottle-pressing pulley via a speed-changing assembly.

[0006] Preferably, the speed change assembly includes a small gear coaxially connected to pulley D and a large gear connected to the axle of the pressure bottle pulley. The large gear is fixedly connected to pulley D as a whole, and the large gear and the small gear mesh.

[0007] Preferably, a tensioning wheel A is provided between the middle of the two first side plates, pressing against the inner side of the first belt. The tensioning wheel A can be adjusted in position along the width direction of the first side plate. A tensioning wheel B is provided between the middle of the two second side plates, pressing against the inner side of the second belt. The tensioning wheel B can be adjusted in position along the width direction of the second side plate.

[0008] Preferably, a square cylindrical seat is provided between the lower parts of the two bottle-pressing side plates. Several guide posts are slidably arranged at equal intervals inside the square cylindrical seat. The guide posts are slidably connected to the sliders provided on the top and bottom plates of the square cylindrical seat. A wear-resistant strip is connected between the lower ends of the guide posts and pressed against the inner side of the lower part of the bottle-pressing pulley. Limiting flanges are provided on both sides of the wear-resistant strip. A spring is sleeved between the limiting step at the lower part of the guide post and the bottom surface of the top plate of the square cylindrical seat.

[0009] Preferably, the ends of the two bottle-pressing side plates are provided with an upper pressure pulley and a lower pressure pulley that are pressed against the inner side of the bottle-pressing belt, and the upper pressure pulley can be adjusted laterally.

[0010] Preferably, the bottle pressing mechanism is mounted on a vertical support via a lifting plate. There are four vertical support columns, and the four corners of the lifting plate are slidably connected to the four vertical support columns via sliding sleeves. The lifting plate is driven to move along the vertical support columns by a lifting screw.

[0011] The beneficial technical effects of this utility model are as follows: This utility model sets up a bottle pressing mechanism above the belt conveyor mechanism. Under the action of the speed change transfer mechanism, the bottle pressing mechanism will run synchronously with the belt conveyor mechanism. When the packaged bottle comes out of the bottle separating device, the bottle pressing mechanism can press down the packaged bottle, so that it is in a stable state on the conveyor belt, avoiding the phenomenon of tipping over due to pushing force. The labeling machine can be continuously and stably operated without manual intervention, which helps to reduce labor costs and improve labeling quality. Attached Figure Description

[0020] Example 1, see appendix Figure 1-2 4-6, a synchronous drive device for pressing and conveying, comprising a belt conveyor mechanism 1 and a bottle pressing mechanism 2 disposed directly above the belt conveyor mechanism. One end of the belt conveyor mechanism 1 is equipped with a worm gear reducer motor 11, and one end of the output shaft 12 of the reducer motor is connected to the roller shaft of the drive roller 13 of the belt conveyor. The conveyor belt 14 is sleeved between the drive rollers 13 at both ends. The bottle pressing mechanism 2 includes two bottle pressing side plates 21 arranged side by side and two bottle pressing pulleys 22 installed at both ends of the bottle pressing side plates 21. The width of the bottle pressing pulleys is smaller than the width of the conveyor belt 14. A bottle pressing belt 23 is sleeved between the two bottle pressing pulleys 22. The other end of the output shaft 12 is connected to the bottle pressing pulley 22 at one end of the bottle pressing mechanism 2 through a speed change conversion mechanism.

[0021] A square tube seat 25 is provided between the lower parts of the two bottle-pressing side plates 21. Several guide posts 26 are slidably arranged at equal intervals inside the square tube seat. Wear-resistant strips 27 are connected between the lower ends of the guide posts 26 and are pressed against the lower inner side of the bottle-pressing pulley 22. A spring 28 is sleeved between the limiting step at the lower part of the guide post 26 and the bottom surface of the top plate of the square tube seat 25. The spring provides vertical pushing force to the guide post. These vertical pushing forces are synchronously transmitted to the wear-resistant strips. The wear-resistant strips 27 are horizontally supported on the inner side of the bottle-pressing belt 23, so that the two ends and the middle of the bottle-pressing belt 23 are on the same plane. This avoids the phenomenon that the bottle-pressing belt 23 is uneven and causes different pressing forces on the packaging bottle at different positions, ensuring the uniformity of the bottle-pressing force and further improving the stability of the packaging bottle.

[0022] The ends of the two bottle-pressing side plates 21 are provided with an upper pressure pulley 51 and a lower pressure pulley 52 that are pressed against the inner side of the bottle-pressing belt 23. The upper pressure pulley 51 and the lower pressure pulley 52 provide tension to the bottle-pressing belt 23 at both ends.

[0023] The bottle pressing mechanism 2 is mounted on the vertical support column 62 via the lifting plate 61. The lifting plate is driven to move along the vertical support column by the lifting screw to change the height of the bottle pressing mechanism 2, so that it can be used for packaging bottles of different sizes.

[0024] Example 2, see appendix Figure 1 , 3 -4. This embodiment is basically the same as Embodiment 1, and the similarities will not be repeated. The difference is that the speed change mechanism includes a first belt assembly 3 and a second belt assembly 4. The first belt assembly 3 includes pulley A 32 and pulley B 33 installed between two first side plates 31 arranged side by side. A first belt 34 is connected between pulley A and pulley B. Pulley A 32 is the driving pulley, which provides power to drive the first belt 34 to rotate between the two pulleys. Pulley A 32 is connected to the output shaft 12. The reduction motor 11 can drive pulley A 32 and pulley B of the bottle pressing mechanism 2 through the output shaft 12. The drive roller 13 of the conveyor mechanism 1 operates synchronously, enabling the two mechanisms to operate synchronously through a single power source. The second belt assembly 4 includes pulley C 42 and pulley D 43 installed between two side-by-side second side plates 41. A second belt 44 connects pulley C 42 and pulley D 43. The corresponding pulley B 33 and pulley C 42 are coaxially connected through a synchronous shaft 45. The power of the first belt assembly 3 is transmitted to the second belt assembly 4 through the synchronous shaft 45. Pulley D 43 is connected to the bottle pressing pulley 22 through a speed change assembly. The second belt assembly transmits power to the bottle pressing pulley 22.

[0025] The speed change assembly includes a small gear 46 coaxially connected to the pulley 43 and a large gear 47 connected to the axle 24 of the bottle pressing pulley. The large gear and the small gear mesh, and the gear set formed by the combination of the large gear 47 and the small gear 46 changes the transmission ratio, so that the belt conveyor mechanism 1 and the bottle pressing mechanism 2 rotate at the same speed, and the bottle pressing belt 23 can press the packaging bottle and move synchronously and stably on the conveyor belt 14.

[0026] A tensioning wheel A is provided between the middle of the two first side plates 31, pressing against the inner side of the first belt 34. A tensioning wheel B is provided between the middle of the two second side plates 41, pressing against the inner side of the second belt 44. The tensioning wheels ensure that the belt is in a taut state, and avoid belt slippage that would cause the conveyor belt 14 and the bottle pressing belt 23 to be out of sync.

[0027] When the pressing and conveying synchronous drive device of this embodiment is running, the reduction motor 11 transmits power to the drive roller 13 and the speed change mechanism of the belt conveyor 1 through the output shaft 12. The drive roller 13 drives the conveyor belt 14 to run, and the packaging bottle runs forward on the conveyor belt 14. After speed change, the speed change mechanism transmits power to the bottle pressing pulley 22. The bottle pressing belt 23 rotates between the two bottle pressing belts 23. The conveyor belt 14 and the bottle pressing belt 23 are in a synchronous running state. When the packaging bottle comes out of the bottle separating device 63, the bottle pressing belt 23 presses against the surface of the bottle cap, providing it with vertical pressing force, so that it is in a stable state on the conveyor belt. There will be no phenomenon of the packaging bottle tipping over due to the pushing force of the bottle separating device 63, ensuring the continuous and stable operation of the labeling machine.
