Description

Technical Field

[0001] This utility model relates to the field of packaging and printing equipment technology, and in particular to a packaging box printing loading and unloading mechanism with ink drying function. Background Technology

[0002] The loading and unloading mechanism for packaging box printing is a key piece of equipment in the packaging box production process, connecting the printing process with subsequent processing steps. Its core functions are to automatically load packaging boxes to be printed, automatically unload and transport printed boxes, and simultaneously coordinate with the printing process to complete auxiliary operations such as ink curing. In the modern packaging industry, as the consumer market's requirements for packaging box appearance precision, production efficiency, and environmental friendliness continue to increase, the printing process needs to achieve rapid ink drying to avoid smudging and ensure print quality. Furthermore, the loading and unloading process must precisely coordinate with the printing equipment and transmission system to meet the demands of large-scale, automated production. The performance of this type of mechanism directly affects the production cycle time, printing pass rate, and overall production line stability, thus playing an irreplaceable role in automated packaging printing production lines.

[0003] Traditional packaging box printing loading and unloading technology has key defects when adapting to different specifications of cardboard, which seriously restricts flexible production: the telescopic arms of traditional mechanisms are mostly designed with a fixed stroke. When facing cardboard of different sizes, it is impossible to accurately adjust the horizontal position of the gripping parts, resulting in small cardboard not being gripped and large cardboard being gripped off-center. In addition, the height adjustment of the gripping parts does not have a limiting guide structure (such as a limiting post) to adapt to cardboard of different thicknesses. Thin cardboard is easily damaged due to height adjustment deviation or cannot be attached to thick cardboard, resulting in a low gripping success rate.

[0004] Therefore, a packaging box printing loading and unloading mechanism with ink drying function is needed to solve the above problems. Utility Model Content

[0028] Example 1

[0029] Reference Figure 1 and Figure 2 This is the first embodiment of the present utility model. This embodiment provides a packaging box printing loading and unloading mechanism with ink drying function, which includes: a conveyor frame 100;

[0030] The loading / unloading assembly 200 includes a connecting seat 201 fixedly connected to one side of the conveyor frame 100. A fixed cylinder 202 is provided above the connecting seat 201. An extension arm 203 is slidably connected to one side of the inner wall of the fixed cylinder 202. A stepper motor 204 is fixedly connected to one side of the inner wall of the fixed cylinder 202. A lead screw 205 is fixedly connected to the rotating shaft of the stepper motor 204. One end of the lead screw 205 is threaded to one end of the inner wall of the extension arm 203. The lead screw 205 is used to control the extension length of the extension arm 203. A suction pump 206 is fixedly connected to the side of the extension arm 203 away from the lead screw 205. The suction pump 206 is used to move the cardboard to be processed to a designated position. The loading / unloading assembly 200 controls the rotation of the suction pump 206 through a rotating mechanism. A lifting mechanism is provided above the rotating mechanism to control the height of the suction pump 206.

[0031] In use, for different sizes of cardboard, first adjust the horizontal gripping position of the suction pump 206 via the loading / unloading assembly 200: Start the stepper motor 204 on the inner wall of the fixed cylinder 202; its rotating shaft drives the lead screw 205 to rotate. Since the lead screw 205 is threadedly connected to the inner wall of the extension arm 203, and the extension arm 203 slides and adapts to the inner wall of the fixed cylinder 202, the rotation of the lead screw 205 is converted into the linear sliding of the extension arm 203 along the fixed cylinder 202, thereby adjusting the extension length of the suction pump 206 at the end of the extension arm 203. For large-sized cardboard, control the extension arm... 203 extends appropriately to expand the gripping range; for small-sized cardboard, the length of the extension arm 203 is shortened to improve gripping accuracy, ensuring that the suction pump 206 can accurately align with the gripping points of different cardboard sizes. Then, the height of the suction pump 206 is adjusted through the lifting mechanism to adapt to cardboard of different thicknesses: the lifting mechanism is activated to cause the fixed cylinder 202 to drive the extension arm 203 and the suction pump 206 to rise and fall as a whole. For thick cardboard, the initial height of the suction pump 206 is increased to avoid squeezing and deformation upon contact; for thin cardboard, the initial height is decreased to ensure that the suction pump 206 can closely adhere to the surface of the cardboard. After the height and horizontal position of the suction pump 206 are adjusted to the correct position, the suction pump 206 is activated to generate negative pressure to adsorb the cardboard. Then, the rotating mechanism drives the suction pump 206 and the cardboard to rotate above the conveyor frame 100. Finally, the negative pressure is released to place the cardboard of different sizes smoothly on the conveyor frame 100, completing the adaptive loading and unloading operation.

[0032] Example 2

[0033] Reference Figure 1 and Figure 4 This is the second embodiment of the present invention. Unlike the previous embodiment, the rotating mechanism includes a gear disk 207 rotatably connected to the bottom of the inner wall of the connecting seat 201. A third stepper motor 212 is fixedly connected to one side of the top of the connecting seat 201. A gear 213 that meshes with the gear disk 207 is fixedly connected to the bottom rotating shaft of the third stepper motor 212.

[0034] The lifting mechanism includes a lifting seat 208 fixedly connected to the top of the gear plate 207. The upper and lower ends of the inner wall of the lifting seat 208 are rotatably connected to a second lead screw 209, which is used to control the height of the fixed cylinder 202.

[0035] The lifting seat 208 is fixedly connected to the top of a second stepper motor 210, the bottom rotating shaft of the second stepper motor 210 is fixedly connected to the top of a second lead screw 209, and two equidistant limiting posts 211 are fixedly connected to the inner wall of the lifting seat 208. The two ends of the second stepper motor 210 are movably sleeved on one end of the limiting post 211.

[0036] One end of the fixed cylinder 202 is threaded to one end of the second lead screw 209, and the end of the fixed cylinder 202 near the second lead screw 209 is movably sleeved with one end of the limiting post 211.

[0037] The conveyor frame 100 is equipped with a straightening component 300 at its top. The straightening component 300 includes a bidirectional lead screw 301 rotatably connected to the top of the conveyor frame 100. Two inclined guide plates 302 are movably connected to each other at both ends of the bidirectional lead screw 301. The inclined guide plates 302 are used to correct the packaging position. A limiting rod 303 is fixedly connected to the top of the conveyor frame 100 near the side of the bidirectional lead screw 301. One side of each of the two inclined guide plates 302 is movably sleeved on one end of the limiting rod 303. The inclined guide plates 302 are driven to rotate by a fourth stepper motor 304 fixedly connected to one end of the conveyor frame 100.

[0038] Among them, a UV curing unit 101 is provided on the top of the conveyor frame 100 near the side of the straightening component 300. The UV curing unit 101 is used to optically cure and dry the ink.

[0039] Parallel baffles 102 are provided at both ends of the top of the conveyor frame 100. The baffles 102 are used to prevent the packaging box from falling off the conveyor belt during the conveying process.

[0040] When using the device, if the rotation angle needs to be adjusted to transfer different sizes of cardboard, the third stepper motor 212 on the top side of the connecting seat 201 is activated. Its bottom rotating shaft drives the gear 213 to rotate, which meshes with the gear disc 207 rotatably connected to the bottom of the inner wall of the connecting seat 201, precisely controlling the rotation angle of the gear disc 207 to adapt the transfer radius of different cardboard sizes. When adjusting the height of the suction pump 206 to adapt to cardboard of different thicknesses, the second stepper motor 210 on the top of the lifting seat 208 is activated. Its bottom rotating shaft drives the second lead screw 209 on the inner wall of the lifting seat 208 to rotate. The fixed cylinder 202, which is threaded to the second lead screw 209 and movably sleeved on the limiting post 211 on the inner wall of the lifting seat 208, will... The system smoothly rises and falls along the limiting post 211, and the height is precisely adjusted by controlling the number of rotations of the second stepper motor 210. After the cardboard is placed on the conveyor frame 100, the fourth stepper motor 304 at one end of the conveyor frame 100 is started, driving the bidirectional lead screw 301 to rotate, which drives the inclined guide plate 302 to adjust the spacing along the limiting rod 303 to adapt to cardboard of different widths, thus completing the position correction. During the transmission, the ultraviolet curing unit 101 at the top of the conveyor frame 100 performs optical curing and drying of ink on cardboard of different specifications after printing, while the parallel baffles 102 at both ends of the top prevent the cardboard from falling out, thus comprehensively improving the adaptability of the mechanism to cardboard of different specifications and the production stability. Finally, the unloading component 200 completes the unloading operation.

[0041] It is worth noting that the entire device is controlled by a controller. Since the controller is a common device and belongs to existing mature technology, its electrical connection relationship and specific circuit structure will not be described in detail here.

[0042] It should be understood that numerous specific implementation decisions can be made during the development of any practical implementation, such as in any engineering or design project. Such development efforts may be complex and time-consuming, but for those skilled in the art who benefit from this disclosure, the development effort will be a routine work of design, manufacturing, and production without requiring much experimentation.
