Description

Technical Field

[0001] This utility model relates to a device for printing on plastic bottles, which performs actions such as gripping, lifting, and discharging plastic bottles. Background Technology

[0002] Plastic bottles are typically manufactured using roller printing because product information needs to be printed on their outer surface. During roller printing, the bottle is placed on rollers to facilitate the printing process. Similar devices already exist to achieve this function, but these devices may have some complex issues. Utility Model Content

[0003] The purpose of this utility model is to provide a cam-type feeding support device, and the technical problem to be solved is to provide a novel cam-type plastic bottle feeding support device.

[0004] The cam-feeding support device includes a rotary drive mechanism and a support mechanism. The rotary drive mechanism has a forward and reverse drive shaft with a first gripping rod and a second gripping rod perpendicularly intersecting each other. The first gripping rod and the second gripping rod are respectively equipped with a first gripping cylinder and a second gripping cylinder to complete the gripping, feeding, and unloading of plastic bottles. The support mechanism has pulleys, guide rails, sliders, and rollers. The guide rails are longitudinally mounted on the sliders, with pulleys mounted on one side and rollers mounted on the other side. The rotary drive mechanism is designed with a cam, which has a variable diameter groove. The pulleys are placed in the variable diameter grooves to drive the pulleys to move longitudinally up and down, thereby driving the rollers to move longitudinally up and down. The rollers support the plastic bottles.

[0005] The rotary drive mechanism has a forward and reverse rotating motor, which is linked with the drive shaft to drive the first gripping rod and the second gripping rod.

[0006] The rotary drive mechanism has a drive wheel, a first gear set, and a second gear set; the drive wheel drives the gears on the first gear set and the second gear set to rotate sequentially through a linkage shaft, and the cam rotates in conjunction with the gears.

[0007] Both the first gear set and the second gear set have two gears arranged symmetrically in the vertical direction, and the two gears are linked by a belt; the gear in the lower position is fixed to the linkage shaft.

[0008] There is a fixing block between the guide rail and the roller.

[0009] The cam feeding support device has a base, which has an outer longitudinal plate and an inner longitudinal plate; the linkage shaft passes through the two inner longitudinal plates in sequence and is fixed on the outer longitudinal plate, and the linkage shaft is fixed to the outer longitudinal plate and the inner longitudinal plate by bearings.

[0010] The linkage shaft passes through one outer longitudinal plate and two inner longitudinal plates respectively, and is fixed to the outer longitudinal plate and inner longitudinal plates by bearings.

[0011] The beneficial effects of this utility model are as follows: by designing a rotary drive mechanism, the first gripping mechanism and the second gripping mechanism are driven to perform forward and reverse movements at a certain frequency, thereby completing the gripping, feeding, and releasing actions of the plastic bottle; by designing a support mechanism, the plastic bottle is supported, which facilitates the printing of the plastic bottle by the material strip; by designing a gripping mechanism composed of a gripping rod and a gripping cylinder, the plastic bottle can be gripped and released quickly.

[0025] Please refer to Figures 1 to 4The cam-feeding support device shown in the figure mainly consists of a rotary drive mechanism 1, a support mechanism 2, a first gripping mechanism 3, a second gripping mechanism 4, and supporting components such as a base 5, a reduction gearbox 6, and a limit rod 7. The rotary drive mechanism 1 drives the first gripping mechanism 3 and the second gripping mechanism 4 to perform the actions of picking up, feeding, and releasing the bottles. The support mechanism 2 supports the plastic bottles being fed to facilitate printing on the material strip. The first gripping mechanism 3 grips and feeds the plastic bottles to the printing position, and the second gripping mechanism 4 releases the printed plastic bottles from the printing position to the storage area. In practical applications, the above components can be further optimized, such as by optimizing local shapes, structures, quantities, and materials, or by using existing components for equivalent replacement, or by adding other components.

[0026] The rotary drive mechanism 1 in the diagram mainly consists of a motor 11, a gearbox 6, a drive shaft 121, a drive wheel 122, a linkage shaft 13, a first gear set 14, a second gear set 15, and two cams 16. The motor 11 drives the drive shaft 121 to rotate via the gearbox 6, which in turn drives the first gripping cylinder 31 and the second gripping cylinder 41 to rotate in both directions. The motor 11 adopts a forward and reverse rotation structure, and the gearbox 6 is a conventional component. The drive shaft 121 maintains linkage with the rotating shaft of the motor 11 to achieve forward and reverse rotation. The drive shaft 121 passes through the outer longitudinal plate 51 and the inner longitudinal plate 52 on the base 5 and is mounted and fixed by bearings. The drive shaft 121 also passes through and is fixed to an integrated block 8, which fixes the first gripping mechanism 3 and the second gripping mechanism 4, which are perpendicularly intersecting each other, together, so that the two mechanisms move simultaneously. The drive wheel 122 adopts a conventional cylindrical wheel structure that can be driven by a belt. This drive wheel 122 is driven to rotate by an additional motor 11 via a belt, which in turn drives the gears on the first gear set 14 and the second gear set 15 to rotate via the linkage shaft 13. This further drives the cam 16 to rotate. The linkage shaft 13, like the drive shaft 121, is a conventional shaft-like structure used to drive the corresponding components. The first gear set 14 and the second gear set 15 are arranged opposite each other, each gear set having two gears, one above the other. When the linkage shaft 13 rotates, the gear in the lower position begins to rotate, thus driving the gear in the upper position to rotate via a belt (not shown in the figure). The transmission ratio of the two gears in the upper and lower positions can be selected as needed. The gear in the upper position is coaxially linked with the cam 16. Two cams 16 are arranged symmetrically opposite each other, with one cam 16 corresponding to one gear set. Each cam 16 has an inwardly recessed annular groove 161 of unequal diameter, which facilitates the placement of the pulley 21 of the support mechanism 2 within the groove 161. The change in the unequal diameter annular trajectory causes the pulley 21 to move longitudinally up and down, thereby driving the roller 24 to perform longitudinal up and down movements, facilitating support for the plastic bottle during printing. In practical applications, the components of the rotary drive mechanism 1 can be further optimized.

[0027] The first gripping mechanism 3 in the figure is designed with a first gripping cylinder 31 and a first gripping rod 32. The first gripping cylinder 31 is a gripping cylinder structure, also known as a clamping cylinder structure. The first gripping rod 32 has a conventional mounting structure, which is used to fix it on the integrated block 8 and move in conjunction with the drive shaft 121, thereby driving the first gripping cylinder 31 to rotate. This facilitates the gripping and feeding action of the plastic bottle. The gripping position is below, and the feeding position is above. The second gripping mechanism 4 is designed with a second gripping cylinder 41 and a second gripping rod 42. The structures of the second gripping cylinder 41 and the second gripping rod 42 are the same as those of the first gripping cylinder 31 and the first gripping rod 32. The second gripping rod 42 is used to fix it on the integrated block 8 and move in conjunction with the drive shaft 121, thereby driving the second gripping cylinder 41 to rotate. This facilitates the feeding and discharging action of the plastic bottle. The feeding position is above, and the discharging position is below. In practical applications, other types of cylinder structures can also be used.

[0028] The support structure shown in the figure has two sets arranged symmetrically. Each support structure is mounted on an inner longitudinal plate 52. Each support structure includes a pulley 21, a guide rail 22, a slider 23, a fixing block 25, and a roller 24. The pulley 21 is positioned within the variable diameter groove 161 to drive the guide rail 22 to move up and down. The slider 23 is fixed to the inner longitudinal plate 52 to facilitate the sliding of the longitudinally mounted guide rail 22. The fixing block 25 is fixed to the guide rail 22 to transmit the lifting and lowering transmission to the roller 24, which supports the plastic bottle. In practical applications, a different support structure can be used to support and position the roller 24.

[0029] The cam 16 feeding support device in the figure is designed with a base 5 structure to facilitate the support and fixation of other components. As shown in the figure, the design includes two outer longitudinal plates 51 and two inner longitudinal plates 52. Both longitudinal plates are arranged longitudinally, with the outer longitudinal plates 51 located outside the inner longitudinal plates 52 and both being penetrated by the drive shaft 121 and the linkage shaft 13 and fixed by bearings. The gears on the first gear set 14 and the second gear set 15 are fixed to the inner longitudinal plates 52. To limit and fix the inner longitudinal plates 52, symmetrically arranged limiting rods 7 can be installed between the two outer longitudinal plates 51, and hollow bushing structures are arranged at corresponding positions on the inner longitudinal plates 52.
