Description

Technical Field

[0001] This application relates to the technical field of wrapping paper printing, and particularly relates to a feeding device for wrapping paper printing. Background Art

[0002] Wrapping paper is used to package and protect various items such as food and handicrafts. When printing on the surface of wrapping paper, a corresponding feeding device is required to feed the stacked wrapping paper into the printing device one by one.

[0003] Currently, a Chinese utility model patent application with a publication date of July 7, 2023 and a publication number of CN219314085U provides a printing wrapping paper feeding mechanism, which includes two base frames. An activity frame is installed at the top between the two base frames. A base is sleeved on the activity frame, and sliding grooves are arranged on both sides inside the base; a lifting mechanism is installed in the sliding groove. The lifting mechanism includes a servo motor and a first lead screw. Transmission bevel gears are installed on the output shaft of the servo motor and the top of the first lead screw. The two transmission bevel gears are perpendicular and meshed. A nut is installed on the first lead screw, a lifting plate is sleeved outside the nut, a fixing seat is installed at the bottom of the lifting plate, a mounting plate is installed at the bottom of the fixing seat, and a first adsorption mechanism and a second adsorption mechanism are installed on the mounting plate. This device can slowly lower the adsorption mechanism through the lifting mechanism, so that after the wrapping paper is continuously transported, the height of the vacuum suction cup is consistent with the height of the topmost wrapping paper, and the problem that the vacuum suction cup is too far away from the wrapping paper and cannot adsorb the wrapping paper to complete the transportation can be solved.

[0004] In the feeding device for wrapping paper printing in the related art, since static electricity may be generated during the production and transportation of wrapping paper, there will be a certain electrostatic attraction between adjacent wrapping papers, which may cause the adsorption mechanism to pick up two or more wrapping papers at a time, thus interfering with the subsequent wrapping paper printing work. Utility Model Content

[0005] The embodiment of this application provides a feeding device for wrapping paper printing, which can improve the technical problem that the adsorption mechanism may pick up multiple wrapping papers at a time in the related art.

[0006] An embodiment of the present application provides a feeding device for wrapping paper printing, including: a frame body, legs, a power mechanism, a feeding mechanism, a picking mechanism, a transmission mechanism, a first rotating shaft, and a vibration wheel. The legs are arranged at the bottom of the frame body. The power mechanism, the feeding mechanism, the picking mechanism, and the transmission mechanism are all arranged on the frame body. The picking mechanism includes a first motor, a first baffle, a second baffle, a first placing plate, a first lead screw, a first optical axis, and a suction mechanism. The first baffle, the second baffle, and the first placing plate are all fixedly arranged on the frame body. One end of the first lead screw is rotatably connected to the first baffle, and the other end of the first lead screw is rotatably connected to the second baffle. One end of the first optical axis is fixedly connected to the first baffle, and the other end of the first optical axis is fixedly connected to the second baffle. The first motor is arranged on the first placing plate, and the output end of the first motor passes through the first baffle and is in transmission connection with the first lead screw. The suction mechanism includes a first transmission plate, a second transmission plate, a connecting bar, a cylinder, a vacuum pump, a third transmission plate, and a suction pipe. Threaded holes are formed in both the first transmission plate and the second transmission plate, and both are in threaded connection with the first lead screw. The first optical axis passes through the first transmission plate and the second transmission plate and is in sliding connection with the first transmission plate and the second transmission plate. One end of the connecting bar is fixedly connected to the first transmission plate, and the other end of the connecting bar is fixedly connected to the second transmission plate. The cylinder is arranged on the first transmission plate, the vacuum pump is arranged on the second transmission plate, the third transmission plate is arranged on the output end of the cylinder, the suction pipe is arranged on the third transmission plate, and the air outlet of the suction pipe is communicated with the air inlet of the vacuum pump through a hose. The first rotating shaft is rotatably connected to the frame body, and the vibration wheel is sleeved on the first rotating shaft

[0007] In the above technical solution of the embodiment of the present application, at least the following technical effects are achieved: When the device works, the cylinder pushes the third transmission plate and the suction pipe to move downward. When the bottom of the suction pipe touches the wrapping paper placed on the feeding device, the vacuum pump provides suction to the bottom of the suction pipe to suck up the contacted wrapping paper. Then the cylinder drives the third transmission plate and the suction pipe to move upward to the top. Then the first motor drives the first lead screw to drive the first transmission plate and the second transmission plate to move towards the transmission mechanism. During this process, the power mechanism drives the first rotating shaft and the vibration wheel to rotate. Since the suction pipe sucks one end of the wrapping paper, the other end of the wrapping paper droops a certain height under the action of gravity and can contact the vibration wheel. If the suction pipe sucks multiple wrapping papers, the vibration wheel pats the wrapping papers to generate gaps between the wrapping papers, and the extra wrapping papers fall off under the action of gravity, ensuring that the picking mechanism transports only one wrapping paper to the transmission mechanism at a time. Then the transmission mechanism transports the wrapping paper to the printer for printing under the drive of the power mechanism

[0008] A feeding device for wrapping paper printing provided by an embodiment of the present application is provided with a vibrating wheel. When the suction mechanism sucks multiple pieces of wrapping paper, the vibrating wheel creates a gap between the wrapping papers to make the redundant wrapping papers fall off, avoiding interference with the printing work.

[0034] Wrapping paper is used to wrap and protect various items such as food and handicrafts. When printing on the surface of wrapping paper, a corresponding feeding device is needed to feed the stacked wrapping paper into the printing device one by one.

The conveyor belt 63 is sleeved on the driving roller 61 and the driven roller 62 and is in transmission connection with the driving roller 61 and the driven roller 62. The pressing wheel 65 is sleeved on the second rotating shaft 64. The power mechanism includes a second motor 31 and a transmission shaft 32.

The transmission shaft 32 is in transmission connection with the first rotating shaft 7 and the second rotating shaft 64 through a pulley and a transmission belt.;

[0040] As can be seen from the above, for the feeding device for wrapping paper printing provided by the embodiments of the present application, when the device is working, the staff can adjust the feeding mechanism according to the size of the wrapping paper. First, rotate the handle 471 to rotate the bidirectional lead screw 47 to drive the left limit plate 42 and the right limit plate 43 to move synchronously so that the distance between them is suitable for the width of the wrapping paper in the left-right direction. Then, turn the second lead screw 49 to drive the rear limit plate 45 to move so that the distance between it and the front limit plate 44 is suitable for the width of the wrapping paper in the front-back direction. Immediately start the device. The air cylinder 574 pushes the third transmission plate 576 and the suction pipe 577 to move downward. When the bottom of the suction pipe 577 touches the wrapping paper placed on the feeding device, if the air cylinder 574 continues to push the third transmission plate 576 downward, the suction pipe 577 remains at a constant height, and the second limit ring 5782 and the third transmission plate 576 compress the spring 578 to make it contract. After the third transmission plate 576 moves to the lowest point, the air cylinder 574 drives the third transmission plate 576 to move upward, and the spring 578 elongates. When the third transmission plate 576 touches the first limit ring 5781, the suction pipe 577 starts to move upward. The vacuum pump 575 provides suction to the bottom of the suction pipe 577 to suck up the wrapping paper in contact. The air cylinder 574 then drives the third transmission plate 576 and the suction pipe 577 to move upward to the top. Then, the first motor 51 drives the first lead screw 55 to rotate, thereby pushing the first transmission plate 571 and the second transmission plate 572 towards the transmission mechanism. During this process, the second motor 31 drives the driving roller 61 to rotate. The driving roller 61 drives the conveyor belt 63 and the driven roller 62 to rotate. The driving roller 61 then drives the rotating shaft to rotate through the gear, and the rotating shaft drives the first rotating shaft 7 and the second rotating shaft 64 to rotate. Since the suction pipe 577 sucks one end of the wrapping paper, the other end of the wrapping paper droops by a certain height under the action of gravity and can contact the rotating vibration wheel 8. If the suction pipe 577 sucks multiple wrapping papers, the vibration wheel 8 beats the wrapping papers to create gaps between the wrapping papers, and the excess wrapping papers fall off into the storage bin 11 under the action of gravity, which is convenient for the staff to collect and reuse them, ensuring that the material taking mechanism transports only one wrapping paper to the transmission mechanism at a time. The suction pipe 577 sends one end of the wrapping paper between the conveyor belt 63 and the pressing wheel 65. The conveyor belt 63 and the pressing wheel 65 cooperate to transport the wrapping paper onto the conveyor belt 63. The first motor 51 drives the first lead screw 55 to rotate, and the first lead screw 55 drives the material taking mechanism back to the initial position to prepare for the next material taking operation.

[0041] In some embodiments, please also refer to Figure 1 and Figure 3, the transmission mechanism further includes a first pressure roller 66, a second pressure roller 67 and a third motor 68. The first pressure roller 66 and the second pressure roller 67 are both rotatably connected to the frame 1. The third motor 68 is arranged at the bottom of the frame 1. The output end of the third motor 68 is drivingly connected to one end of the second pressure roller 67 through a pulley and a transmission belt. One end of the second pressure roller 67 close to the third motor 68 is drivingly connected to one end of the first pressure roller 66 close to the third motor 68 through a gear; a transfer plate 12 is further arranged on the frame 1, and both ends of the transfer plate 12 are fixedly connected to the frame 1.

[0042] With such an arrangement, when the wrapping paper is transported to the conveyor belt 63, the third motor 68 drives the second pressure roller 67 to rotate, and the second pressure roller 67 drives the first pressure roller 66 to rotate. When the wrapping paper is transported to the tail of the conveyor belt 63, the head of the wrapping paper first contacts the top of the transfer plate 12. The tail of the wrapping paper continues to be pushed by the conveyor belt 63, and the wrapping paper continues to move forward. After the head of the wrapping paper passes through the transfer plate 12, it enters between the first pressure roller 66 and the second pressure roller 67. The first pressure roller 66 and the second pressure roller 67 cooperate to continue feeding the wrapping paper into the subsequent printing device.

[0043] The above are only the preferred embodiments of the present application and are not intended to limit the present application. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
