Description

Technical Field

[0001] This utility model relates to the technical field of flipping devices, specifically to a flipping device for cardboard printing machines. Background Technology

[0002] In the industrial printing industry, common printing presses can only print on one side. Therefore, when double-sided printing is required, the paper needs to be flipped over for a second printing. This process requires a flipping device.

[0003] The existing publicly available technology, application number CN202320205973.3, describes a cardboard printing flipping device. During operation, a flipping plate is rotatably connected to the root of the flipping rod on the side that contacts the cardboard. A pressing block is provided on the flipping plate. When the pressing block is located above the corresponding flipping rod, gravity causes friction and deceleration on the cardboard. When the pressing block is located below the corresponding flipping rod, it droops with the flipping plate, causing the cardboard to fall due to the loss of its restraint. Each rotation of the shaft removes a piece of cardboard from the slide plate, and simultaneously, a piece of cardboard from the flipping assembly falls onto the conveyor belt, which then transports it to the feed inlet of the cardboard printing machine, thus achieving continuous and automatic cardboard flipping.

[0004] However, the above-mentioned patent still has certain drawbacks in use: although it can achieve the flipping operation of cardboard, the overall structure is fixed, and the cardboard size that can be applied is relatively limited. It cannot flexibly flip different types of cardboard, and different sizes of equipment are required to process cardboard of different sizes, which reduces the practicality of the device and the overall use effect is not ideal.

[0005] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0006] (a) Technical problems to be solved To address the shortcomings of existing technologies, this utility model provides a flipping device for cardboard printing machines, which has the advantages of wide applicability, strong practicality, and strong flipping stability, thereby solving the problems mentioned in the background technology.

[0007] (II) Technical Solution To achieve the advantages of wide applicability, strong practicality, and high material handling stability, the specific technical solution adopted by this utility model is as follows: A flipping device for a cardboard printing machine includes a support frame and a flipping disc. A drive shaft is rotatably connected to the top center of the support frame. One end of the drive shaft passes through one side of the support frame and is connected to a motor. The flipping disc is symmetrically fitted around the outer periphery of the drive shaft. Several sets of receiving grooves are evenly arranged around the surface of the flipping disc. An adjustment groove is formed on one side of the receiving groove on the surface of the flipping disc. An adjustment rod is slidably connected inside the adjustment groove. One end of the adjustment rod passes through one side of the receiving groove and is connected to a limiting plate.

[0008] Furthermore, the material turning disc is connected to the drive shaft by fastening bolts.

[0009] Furthermore, several sets of first positioning holes are provided around the surface of the material turning disc and the surface of the drive shaft.

[0010] Furthermore, several sets of second positioning holes are provided on the surface of the adjusting rod and on the surface between the receiving groove and the adjusting groove.

[0011] Furthermore, an L-shaped groove is provided at the bottom of the limiting plate.

[0012] Furthermore, a rubber pad is provided on the surface of the limiting plate.

[0013] Furthermore, the support frame is made of metal.

[0014] (III) Beneficial Effects Compared with the prior art, the present invention provides a turning device for a cardboard printing machine, which has the following advantages: (1) This utility model adopts a flipping disc and a limiting plate. In actual use, the personnel can change the distance between the two flipping discs by moving them relative to each other, so as to adapt to the flipping of cardboard of different sizes. Then, the personnel can also move the adjusting rod up and down according to the thickness of the cardboard to be flipped, so that the adjusting rod and the second positioning hole on the surface of the flipping disc are aligned. Then, the personnel can fix the adjusting rod with bolts and other structures, so that the distance between the limiting plate and the inner wall of the receiving groove changes, which makes it easier to better accommodate the cardboard. Thus, one set of devices can flip multiple sets of different types of cardboard, improving the practicality of the device. It has the advantages of wide applicability and strong practicality.

[0015] (2) By using a limiting plate, the cardboard can be blocked by the L-shaped groove on the surface of the limiting plate when flipping. This prevents the cardboard from falling off the side when the device vibrates, thus ensuring the stability of the flipping. At the same time, the adjustment of the limiting plate can reduce the height of the cardboard, thus preventing the cardboard from fluctuating significantly, and thus better flipping the cardboard. It has the advantage of strong flipping stability. Attached Figure Description

[0028] Working Principle: In actual use, the operator can change the distance between the two flipping discs 3 by moving them relative to each other, thus accommodating the flipping of cardboard of different sizes. After the flipping discs 3 are adjusted, they can be connected to the first positioning hole 7 on the surface of the drive shaft 6 by fastening bolts 5, thereby fixing the flipping discs 3. Then, the operator can move the device between the conveyor belts of the two cardboard printing machines, so that the conveyor belt is positioned between the two flipping discs 3. Next, the operator can also move the adjusting rod 10 up and down according to the thickness of the cardboard to be flipped, so that the adjusting rod 10 and the second positioning hole 11 on the surface of the flipping disc 3 are aligned. Then, the operator can fix the adjusting rod 10 with bolts and other structures, thereby changing the distance between the limiting plate 8 and the inner wall of the receiving groove 4, which facilitates better reception of the cardboard. Then, the cardboard is transported by the conveyor belt. The cardboard can be conveyed in one step. When the cardboard moves to be level with the receiving groove 4, it will be inserted into the receiving groove 4 and supported by two sets of flipping discs 3. Then, the rotation of the motor 2 will drive the drive shaft 6 to rotate, thereby realizing the rotation operation of the flipping discs 3. When the cardboard is flipped to the other side of the conveyor belt, the cardboard can be unloaded through friction with the conveyor belt, thus realizing a complete cardboard flipping operation. Moreover, during the flipping, the cardboard can be blocked by the L-shaped groove on the surface of the limiting plate 8. This can prevent the cardboard from falling off the side when the device vibrates, thus ensuring the stability of the flipping. At the same time, the adjustment of the limiting plate 8 can also reduce the height of the cardboard to be received, thereby preventing the cardboard from fluctuating greatly, thus better flipping the cardboard and improving the overall flipping stability. The device as a whole has the advantages of wide applicability, strong practicality and strong flipping stability.
