Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of printing apparatus, and more specifically, to a driving mechanism for printing on bottles. Background Technology
[0002] In industrial production, hot stamping and pad printing are two widely used techniques for printing patterns on the outer walls of curved bottles such as glass bottles. While these two techniques can meet basic printing needs, in mass production scenarios, to achieve continuous operation, a rotary conveyor system is usually required. That is, the bottles are transferred sequentially onto a rotating turntable, which then precisely transports them to the printing press station to complete the printing operation.
[0003] Because the outer walls of bottles are mostly curved, a drive device is needed to rotate the bottle during the printing process to ensure the complete rendering of the pattern on the curved surface. However, the design of existing conventional printing equipment has significant limitations: to coordinate with the continuous operation of the turntable, an independent drive device must be installed on the turntable for each bottle station. When the bottle arrives at the printing unit, the corresponding drive device is triggered to rotate the bottle. This design not only makes the equipment structure extremely complex, but the excessive number of drive units also increases the probability of mechanical failure. At the same time, to coordinate the operation rhythm of multiple drive devices with the turntable and printing press, complex programming and real-time control are required, which increases the manufacturing cost of the equipment and brings great inconvenience to later maintenance.
[0004] Based on the above problems, designing a simple and efficient printing drive device has become an urgent need in the industry. Utility Model Content

[0007] Furthermore, the elastic component includes a spring connected to the lower side of the first friction plate.
[0008] Furthermore, the fixing device also includes a support plate horizontally disposed at the bottom of the groove; the connecting rod passes through the support plate and is slidably connected to the support plate; the upper end of the spring is connected to the first friction plate, and the lower end of the spring is fixedly connected to the support plate.
[0009] Furthermore, the fixing block has a first through hole at its bottom, the support plate has a second through hole, and the connecting rod passes through both the first and second through holes. The through hole is circular, the projection of the connecting rod on the horizontal plane is non-circular, and the second through hole is a shape adapted to the connecting rod.
[0010] Furthermore, a third through hole is provided in the center of the turntable, and a vertically arranged column is provided in the center of the base plate; the column is arranged through the through hole, and the turntable is rotatably connected to the column.
[0011] Furthermore, the pressing device includes a driving block located directly above the first friction plate, a limiting groove formed on the lower surface of the driving block, a push rod rotatably connected to the upper side of the driving block and vertically arranged, and a horizontal bar connected to the push rod and horizontally arranged; the third driving device includes a telescopic cylinder for driving the horizontal bar to rise and fall; the telescopic cylinder is vertically arranged, the cylinder body of the telescopic cylinder is fixedly connected to the column, and the movable end of the telescopic cylinder abuts against the lower side of the horizontal bar.
[0012] Furthermore, the pressing device also includes a pair of limiting rods vertically disposed on the lower side of the crossbar, and a pair of limiting tubes vertically disposed and fixedly connected to the column; one of the limiting rods is slidably disposed in one of the limiting tubes.
[0013] Furthermore, the first driving device includes a driving tube fixedly disposed on the lower side of the turntable, a driven wheel sleeved on the outer wall of the driving tube, a first motor fixedly disposed on the base plate, a driving wheel disposed on the output shaft of the first motor, and a transmission belt for connecting the driving wheel and the driven wheel; the driving tube is sleeved on the outer wall of the column, and a limiting ring is provided on the outer wall of the column, the upper side of the limiting ring abutting against the lower end of the driving tube.
[0014] Furthermore, the second driving device includes a second motor fixedly connected to the base plate, the output shaft of the second motor being fixedly connected to the driving disk, and the output shaft of the second motor being vertically arranged.
[0015] The technical solution of this utility model has at least the following advantages and beneficial effects: The driving mechanism for printing on bottles can, during use, use a robotic arm to grasp the bottle and place it vertically in the groove on the fixed block (the lower end of the bottle presses against the first friction plate). Then, the first driving device drives the turntable to rotate, gradually rotating the bottle to the printing device. When the bottle moves to the printing device, the third driving device drives the pressing device to descend, contacting the upper end of the bottle, and then pressing the bottle down. At this time, the bottle is in close contact with the first friction plate, and the bottle, the first friction plate, the connecting rod, and the second friction plate descend until the second friction plate is in contact with the driving device. When the rotating discs are in close contact, the second drive device drives the drive disc to rotate. The friction between the drive disc and the second friction plate drives the second friction plate to rotate. The second friction plate drives the first friction plate to rotate via a connecting rod. The friction between the first friction plate and the bottom of the bottle drives the bottle to rotate. During rotation, printing is performed on the outer wall of the bottle. After printing, the third drive device drives the pressing device to move upward. Under the action of the elastic component, the bottle, the first friction plate, and the second friction plate move upward, and the second friction plate disengages from the drive disc. Then the turntable continues to rotate. When the bottle moves to the robotic arm, the printed bottle is removed from the groove. This design simplifies the structure of the turntable and related drive devices. Only one drive disc and one drive device are needed to drive each bottle to rotate and print. Power is transmitted through friction, eliminating the need to consider errors during alignment, thus resulting in faster operation. Attached Figure Description

Detailed Implementation
[0025] Example
[0026] The following description, in conjunction with specific embodiments, further illustrates the points, as shown in the appendix. Figure 1 -Appendix Figure 8As shown, the driving mechanism for bottle printing in this embodiment includes a horizontally arranged base plate 10, a turntable 20 horizontally arranged and rotatably disposed above the base plate 10, a first driving device 21 for driving the turntable 20 to rotate, a plurality of slots 22 formed on the edge of the turntable 20, a plurality of fixing devices 23 disposed on the edge of the turntable 20, a driving disk 11 horizontally disposed on the upper edge of the base plate 10, a second driving device 111 for driving the driving disk 11 to rotate, a pressing device 30 disposed directly above the driving disk 11, and a third driving device for driving the pressing device 30 to rise and fall. 36; a fixing device 23 is fixedly disposed on the lower side of a slot 22, a turntable 20 is disposed between the drive disk 11 and the pressing device 30, and the turntable 20 is disposed directly below one of the fixing devices 23; the fixing device 23 includes a fixing block 231, a groove 232 opened on the upper side of the fixing block 231, a first friction plate 233 horizontally disposed in the groove 232, a second friction plate 234 horizontally disposed below the fixing block 231, an elastic component connected to the first friction plate 233, and a connecting rod 235 for connecting the first friction plate 233 and the second friction plate 234. Specifically, during use, the robotic arm 40 can grasp the bottle 60 and place it vertically in the groove 232 on the fixed block 231 (the lower end of the bottle 60 presses against the first friction plate 233). Then, the first driving device 21 drives the turntable 20 to rotate, gradually rotating the bottle 60 to the printing device 50. When the bottle 60 moves to the printing device 50, the third driving device 36 drives the pressing device 30 to descend. The pressing device 30 contacts the upper end of the bottle 60 and then presses the bottle 60 down. At this time, the bottle 60 is in close contact with the first friction plate 233, and the bottle 60, the first friction plate 233, the connecting rod 235, and the second friction plate 234 descend until the second friction plate 234 is in close contact with the driving disk 11. At this time, the second driving device 111 drives... The drive disk 11 rotates, and the friction between the drive disk 11 and the second friction plate 234 drives the second friction plate 234 to rotate. The second friction plate 234 drives the first friction plate 233 to rotate via the connecting rod 235. The friction between the first friction plate 233 and the bottom of the bottle 60 drives the bottle 60 to rotate. During the rotation, printing can be performed on the outer wall of the bottle 60. After printing, the third drive device 36 drives the pressing device 30 to move upward. Under the action of the elastic component, the bottle 60, the first friction plate 233 and the second friction plate 234 move upward. The second friction plate 234 disengages from the drive disk 11, and then the turntable 20 continues to rotate. When the bottle 60 moves to the robotic arm 40, the printed bottle 60 is taken out from the groove 232. In this way, the structure of the turntable 20 and related drive devices is simpler. Only one drive disk 11 and a second drive device 111 are needed to drive each bottle 60 to rotate and print. Power is transmitted through friction, and there is no need to consider the error during the matching process, so the operation is faster.It should be noted that in this embodiment, the robotic arm 40, printing device 50, etc. are only shown in their positional relationship. Their specific structure can be achieved using conventional equipment, and no modifications have been made to them in this embodiment.
[0027] The elastic component in this embodiment includes a spring 236 connected to the lower side of the first friction plate 233. Specifically, the pressing device 30 presses the bottle 60 downward, thereby compressing the spring 236 through the bottle 60, allowing the second friction plate 234 to contact and drive the drive disc 11. When the pressing device 30 leaves the bottle 60, the spring 236 rebounds, causing the second friction plate 234 to separate from the drive disc 11. The drive disc 11 and the second friction plate 234 can be made of materials with a high coefficient of friction, such as ceramic or rubber, but the first friction plate 233 is preferably made of rubber to avoid damage to the bottle 60.
[0028] The fixing device 23 in this embodiment also includes a support plate 237 horizontally disposed at the bottom of the groove 232; a connecting rod 235 passes through the support plate 237 and is slidably connected to the support plate 237; the upper end of the spring 236 is connected to the first friction plate 233, and the lower end of the spring 236 is fixedly connected to the support plate 237. The bottom of the fixing block 231 has a first through hole, the support plate 237 has a second through hole, and the connecting rod 235 is disposed through both the first through hole and the second through hole; the through hole is circular, the projection of the connecting rod 235 on the horizontal plane is non-circular, and the second through hole is a shape adapted to the connecting rod 235. Specifically, the spring 236 can be clamped by the support plate 237 and the first friction plate 233 to prevent the spring 236 from contacting the inner wall of the groove 232. The non-circular structure allows the spring 236, the first friction plate 233, the connecting rod 235, the support plate 237, and the second friction plate 234 to rotate synchronously. Lubricant needs to be applied to the groove 232 or a flat needle roller bearing needs to be used to reduce friction.
[0029] In this embodiment, the turntable 20 has a third through hole in its center, and the base plate 10 has a vertically arranged column 12 in its center; the column 12 passes through the through hole, and the turntable 20 is rotatably connected to the column 12. Specifically, the column 12 can continue to support the turntable 20.
[0030] The pressing device 30 in this embodiment includes a driving block 31 located directly above the first friction plate 233, a limiting groove formed on the lower surface of the driving block 31, a push rod 32 rotatably connected to the upper side of the driving block 31 and vertically arranged, and a horizontal bar 33 connected to the push rod 32 and horizontally arranged; the third driving device 36 includes a telescopic cylinder 361 for driving the horizontal bar 33 to rise and fall; the telescopic cylinder 361 is vertically arranged, the cylinder body of the telescopic cylinder 361 is fixedly connected to the column 12, and the movable end of the telescopic cylinder 361 abuts against the lower side of the horizontal bar 33. Specifically, the movable end of the telescopic cylinder 361 is not fixedly connected to the crossbar 33. When the movable end of the telescopic cylinder 361 descends, the crossbar 33, push rod 32, and drive block 31 descend under their own weight. After descending, the upper end of the bottle 60 is inserted into the limiting groove on the lower side of the drive block 31, and under the weight of the crossbar 33, push rod 32, etc., the bottle 60 continues to be pressed down, causing the second friction plate 234 to contact the drive disk 11. Then, during the rotation of the bottle 60, the drive block 31 also rotates. After printing is completed... The movable end of the telescopic cylinder 361 moves upward, pushing the crossbar 33, push rod 32, drive block 31 and other structures upward, so that the drive block 31 is separated from the bottle body 60. In this way, only the weight of the crossbar 33, push rod 32, drive block 31 and other components needs to be controlled to control the downward pressure of the drive block 31 on the bottle body 60. Moreover, this downward pressure is not affected by the telescopic cylinder 361. Therefore, the downward pressure on the bottle body 60 is more stable. Furthermore, the downward pressure on the bottle body 60 can be adjusted by setting counterweights of different weights on the crossbar 33.
[0031] The pressing device 30 in this embodiment also includes a pair of limiting rods 35 vertically disposed below the crossbar 33, and a pair of limiting tubes 34 vertically disposed and fixedly connected to the column 12; one limiting rod 35 is slidably disposed in one limiting tube 34. Specifically, the setting of the limiting rods 35 and the limiting tubes 34 can ensure that the crossbar 33, push rod 32 and other structures can be raised and lowered stably.
[0032] In this embodiment, the first driving device 21 includes a driving tube 211 fixedly mounted on the lower side of the turntable 20, a driven wheel 212 sleeved on the outer wall of the driving tube 211, a first motor 213 fixedly mounted on the base plate 10, a driving wheel mounted on the output shaft of the first motor 213, and a transmission belt 214 connecting the driving wheel and the driven wheel 212. The driving tube 211 is sleeved on the outer wall of the column 12, and a limiting ring 13 is provided on the outer wall of the column 12. The upper side of the limiting ring 13 abuts against the lower end of the driving tube 211. Specifically, the limiting ring 13 can support the overall structure of the turntable 20, and the first motor 213 and the transmission belt 214 can drive the turntable 20 to rotate. The first motor 213 needs to be a high-precision servo motor, and in addition to the transmission belt 214, chain and sprocket transmission or direct gear drive can also be used.
[0033] In this embodiment, the second drive device 111 includes a second motor 112 fixedly connected to the base plate 10. The output shaft of the second motor 112 is fixedly connected to the drive disk 11, and the output shaft of the second motor 112 is vertically arranged. Specifically, the second motor 112 also needs to be driven by a high-precision servo motor. A conventional reduction gear structure or a transmission structure for transition can be set between the second motor 112 and the drive disk 11.
[0034] In summary, the driving mechanism for bottle printing in this embodiment can, during use, use a robotic arm 40 to grip the bottle 60 and place it vertically in the groove 232 on the fixing block 231 (the lower end of the bottle 60 presses against the first friction plate 233). Then, the first driving device 21 drives the turntable 20 to rotate, gradually rotating the bottle 60 to the printing device 50. When the bottle 60 moves to the printing device 50, the third driving device 36 drives the pressing device 30 to descend. The pressing device 30 contacts the upper end of the bottle 60 and then presses the bottle 60 down. At this time, the bottle 60 is in close contact with the first friction plate 233, and the bottle 60, the first friction plate 233, the connecting rod 235, and the second friction plate 234 descend until the second friction plate 234 is in close contact with the driving disk 11. The driving device 111 drives the driving disk 11 to rotate. The friction between the driving disk 11 and the second friction plate 234 drives the second friction plate 234 to rotate. The second friction plate 234 drives the first friction plate 233 to rotate through the connecting rod 235. The friction between the first friction plate 233 and the bottom of the bottle body 60 drives the bottle body 60 to rotate. During the rotation, printing can be performed on the outer wall of the bottle body 60. After printing, the third driving device 36 drives the pressing device 30 to move upward. Under the action of the elastic component, the bottle body 60, the first friction plate 233 and the second friction plate 234 move upward. The second friction plate 234 disengages from the driving disk 11. Then the turntable 20 continues to rotate. When the bottle body 60 moves to the robotic arm 40, the printed bottle body 60 can be taken out from the groove 232. This makes the structure of the turntable 20 and related drive devices simpler. Only one drive plate 11 and a second drive device 111 are needed to drive each bottle 60 to rotate and print. Power is transmitted through friction, and there is no need to consider the error during the fit, so the operation is faster.
[0035] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
