Description

Technical Field

[0001] The present application relates to the technical field of packaging printing, and in particular to a flipping mechanism for packaging printing. Background Art

[0002] Package printing refers to the process of printing various patterns, texts, logos or brand information on packaging products. This process is crucial in the packaging industry because it not only provides the appearance of the product, but also conveys the brand image, product information and marketing information. Many exquisite cardboard packaging products usually use double-sided printing.

[0003] The traditional double-sided printing method of cardboard is to turn it over manually, which is time-consuming and labor-intensive. Some equipment uses a cardboard cardboard to turn the cardboard over. During the turning process, if you want to ensure that the cardboard can be engaged with the card slot every time, you must use a stepper motor to drive it at a fixed angle. The high price of the stepper motor makes the printing cost high. Therefore, in order to solve the above problem, this application provides a flipping mechanism for packaging printing.

[0004] The above information disclosed in the background technology is only used to increase the understanding of the background technology of the present application, and therefore, it may include information that does not constitute the prior art known to ordinary technicians in the field. Utility Model Content

[0005] In order to solve the problem that manual flipping is time-consuming and labor-intensive and the cost of stepper motors is high, the present application provides a flipping mechanism for packaging printing.

[0006] The present application provides a flipping mechanism for packaging printing, comprising two conveyor belts, a plurality of rotating disks rotatably arranged between the conveyor belts, the rotating disks having six evenly distributed positioning slots, a motor arranged between the two conveyor belts, a second cross bar fixedly connected to the driving shaft of the motor, when the second cross bar rotates one circle, the rotating disks of the positioning slots rotate, and the lower walls of the positioning slots are flush with the upper walls of the conveyor belts.

[0007] Preferably, four support frames are fixedly arranged between the two conveyor belts, and the support frames are through-arranged and rotatably connected to a rotating rod.

[0008] Preferably, the rotating disks are sleeved on the outer wall of the rotating rod and are coaxially fixedly connected thereto.

[0009] Preferably, one end of the rotating rod is coaxially fixedly connected with a groove wheel, and the groove wheel is provided with six evenly distributed toggle grooves, and the number of the toggle grooves is the same as the locking grooves.

[0010] Preferably, the side wall of the support frame is rotatably connected to a first cross bar, and the first cross bar is coaxially fixedly connected to a disc.

[0011] Preferably, a lever is fixedly connected to the side wall of the disc, and the lever cooperates with the toggle groove. The lever rotates and is slidably connected to the toggle groove.

[0012] Preferably, a transmission belt is wound around the second cross bar and the first cross bar, and the second cross bar and the first cross bar are driven by the transmission belt.

[0013] Preferably, a printing component is fixedly arranged above the conveyor belt.

[0014] In summary, this application includes the following beneficial technical effects:

[0015] The packaging cardboard on the conveyor belt is printed by the printing component, and the cardboard is inserted into the card slot through the conveyor belt. During the rotation of the rotating disk, the cardboard is driven to press against the conveyor belt on the other side to realize the flipping of the packaging cardboard. The motor is started to rotate the second crossbar. The second crossbar rotates one circle, and the first crossbar drives the disc to rotate one circle. Therefore, the lever rotates one circle and drives the groove wheel to rotate sixty degrees. At this time, the rotating rod drives the rotating disc to rotate sixty degrees, and the card slot below rotates sixty degrees to be flush with the conveyor belt for the next round of transmission and flipping. Compared with the traditional method, this mechanism does not require manual flipping or the use of expensive stepping motors. It only needs to adjust the speed of the conveyor belt and the motor to realize the rapid flipping of the packaging cardboard. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0020] The following is combined with Figure 1-3 This application is described in further detail.

[0021] Embodiment 1

[0022] Reference Figure 1-3A packaging printing flip mechanism includes two conveyor belts 1, and a printing component 2 is fixedly arranged above the conveyor belts 1. The printing component 2 is a common packaging cardboard printing machine on the market, which is an existing mature technology and will not be described here.

[0023] A plurality of rotating disks 5 are rotatably arranged between the conveyor belts 1, and six evenly distributed positioning grooves 6 are arranged through the rotating disk 5. A motor is arranged between the two conveyor belts 1, and the driving shaft of the motor is fixedly connected to a second cross bar 12. When the second cross bar 12 rotates one circle, the rotating disk 5 with the positioning groove 6 rotates, and the lower wall of the positioning groove 6 is flush with the upper wall of the conveyor belt 1.

[0024] Four support frames 4 are fixedly arranged between the two conveyor belts 1, and the support frames 4 are arranged through and rotatably connected with the rotating rod 3. The rotating disks 5 are all sleeved on the outer wall of the rotating rod 3 and are coaxially fixedly connected thereto. A groove wheel 7 is coaxially fixedly connected to one end of the rotating rod 3, and the groove wheel 7 is arranged through with six evenly distributed toggle grooves 13. The toggle grooves 13 and the positioning grooves 6 may not be six, as long as both are evenly arranged and the number is the same.

[0025] The side wall of the support frame 4 is rotatably connected with the first cross bar 10, and the second cross bar 12 and the first cross bar 10 are wound with a transmission belt 11, and the second cross bar 12 and the first cross bar 10 are transmitted through the transmission belt 11. The first cross bar 10 is coaxially fixedly connected with the disk 9. The side wall of the disk 9 is fixedly connected with a lever 8, and the lever 8 cooperates with the toggle groove 13. The lever 8 rotates and is slidably connected with the toggle groove 13. The lever 8 rotates to resist the toggle groove 13 and drive the groove wheel 7 to rotate. During the process of rotating one circle of the lever 8, it will slide out of a toggle groove 13 and slide into the next toggle groove 13, pushing the groove wheel 7 to rotate sixty degrees.

[0026] In the actual process of printing the packaging cardboard, the printing assembly 2 first prints the packaging cardboard on the conveyor belt 1, and the cardboard passes through the conveyor belt 1 and is inserted into the card slot 6. During the rotation of the rotating disk 5, the cardboard is driven to press against the other side of the conveyor belt 1, so that the packaging cardboard is turned over;

[0027] Starting the motor causes the second cross bar 12 to rotate. The second cross bar 12 rotates one circle, and the first cross bar 10 drives the disc 9 to rotate one circle. Therefore, the lever 8 rotates one circle to drive the groove wheel 7 to rotate sixty degrees. At this time, the rotating rod 3 drives the rotating disk 5 to rotate sixty degrees, and the positioning groove 6 below rotates sixty degrees to be flush with the conveyor belt 1 for the next round of transmission and flipping. This mechanism does not require manual flipping or the use of expensive stepper motors. It only needs to adjust the speed of the conveyor belt 1 and the motor to achieve rapid flipping of the packaging cardboard.
