Description

Technical Field

[0001] This utility model relates to the field of flipping fixtures, and in particular to an automatic flipping fixture for bidirectional printing of square boxes. Background Technology

[0002] A printing fixture is a tool or device used to fix workpieces in the production process, which can improve production efficiency and reduce losses. The main function of the fixture is to fix the workpiece and keep it in a precise position during processing, inspection or assembly. Traditional printing fixtures can mostly only perform single-sided printing and drying, which is inefficient. The fixture vibrates a lot during flipping and it is difficult to distinguish the flipping direction of the square box fixture, which can easily lead to printing errors. This is especially true for commonly used office / home items such as drawers / storage boxes, which have side openings and different thicknesses at the top and bottom, requiring positioning to prevent the printed information from being reversed during the production process, causing defects.

[0003] An automatic flipping fixture for bidirectional printing of square boxes is proposed. By adding a reversing cylinder, two sides can be printed simultaneously during production. The side of the square box fixture is hollowed out to ensure that the square box fixture flips smoothly. At the same time, the upper and lower sides of the square box fixture are wrapped with baffles of different lengths to facilitate the identification of the wall thickness of the square box fixture and effectively prevent printing direction errors. Utility Model Content

[0004] In order to overcome at least one of the problems mentioned above, this utility model proposes an automatic flipping fixture for bidirectional printing of square boxes, which solves the existing problems.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0009] Preferably, a second fixing groove is provided on one side of the rotating plate, and a second fixing bolt is connected through the second fixing groove, with one end of the second fixing bolt penetrating inside the connecting plate.

[0010] Preferably, a rotating shaft is provided on the side of the rotating plate on one side of the first bracket, and a rotating bearing is provided inside the first bracket, with the rotating shaft passing through the rotating bearing. A rotating disk is provided on the side of the rotating plate on one side of the second bracket, and the rotating disk is installed inside the second bracket. A third fixing bolt is connected through the rotating plate on one side of the second bracket, with one end of the third fixing bolt passing through the rotating disk.

[0011] Preferably, a fourth fixing bolt is connected through the inside of the square box fixture, and a fourth fixing nut is provided at the other end of the fourth fixing bolt. The fourth fixing nut is installed on one side of the connecting plate.

[0012] Preferably, a fixing plate is provided below the connection between the rotating plate and the connecting plate, and a fifth fixing bolt is connected through both ends of the fixing plate.

[0013] Preferably, a sixth fixing bolt is connected through the inside of the second bracket, and one end of the sixth fixing bolt passes through the inside of the rotary cylinder.

[0014] Preferably, the upper and lower baffles are of different lengths, and a longer baffle is wrapped around the outer side of the thicker side of the fixture, while a shorter baffle is wrapped around the outer side of the thinner side of the fixture.

[0015] The beneficial effects of this utility model are as follows:

[0016] 1. The square box fixture has symmetrical perforated grooves on both sides, which can effectively enable the square box fixture to be flipped smoothly.

[0017] 2. The rotating plate 7 is rotated along with the rotating disk by a rotary cylinder, and the rotating shaft rotates inside the rotating bearing, causing the square box fixture to flip.

[0018] 3. The lengths of the retaining strips on the thick and thin sides of the jig are different. Users can distinguish the rotation direction of the jig by the length of the retaining strips, which can effectively reduce the possibility of printing errors.

[0019] In summary, by adopting the structure of this utility model, the problems of traditional printing fixtures being mostly limited to single-sided printing and drying, resulting in low efficiency, significant vibration during fixture flipping, and difficulty in distinguishing the flipping direction of the square box fixture, which can easily lead to printing direction errors can be better solved.

Rotating plates 7 are mounted inside both the first support 5 and the second support 6. A connecting plate 10 is mounted on one side between the rotating plates 7, and a square box fixture 15 is mounted on one side of the connecting plate 10. The square box fixture 15 has symmetrically arranged perforated grooves 19 on both sides, which effectively allow the square box fixture 15 to flip smoothly. A fixture thickness surface 16 is provided on the top of the square box fixture 15, and the bottom of the square box fixture 15... The square fixture 15 is provided with a thin surface 17, and both the thick surface 16 and the thin surface 17 are provided with baffles 18. A rotary cylinder 25 is installed on one side of the second bracket 6. The rotary cylinder 25 is used to flip the square fixture 15. A conduit 26 is connected to one side of the rotary cylinder 25. An air pump 27 is provided at the other end of the conduit 26. The air pump 27 is used to control the rotary cylinder 25. A sixth fixing bolt 24 is connected through the inside of the second bracket 6. One end of the sixth fixing bolt 24 passes through the inside of the rotary cylinder 25. The sixth fixing bolt 24 is used to fix the rotary cylinder 25 on one side of the second bracket 6.

[0031] Reference Figure 1 and Figure 2 The base 2 has a first fixing groove 3 symmetrically opened on the top, and a first fixing bolt 4 is connected through the first fixing groove 3. The first fixing groove 3 is used to install the first fixing bolt 4. The first fixing bolt 4 is used to fix the base 2 to the chassis 1. The rotating plate 7 has a second fixing groove 8 on one side, and a second fixing bolt 9 is connected through the second fixing groove 8. The second fixing groove 8 is used to hide the second fixing bolt 9 to prevent loosening during rotation. One end of the second fixing bolt 9 passes through the inside of the connecting plate 10. The rotating plate 7 and the connecting plate 10 are fixed by the second fixing bolt 9.

[0032] Reference Figure 6 A rotating shaft 11 is provided on the side of the rotating plate 7 on one side of the first bracket 5, and a rotating bearing 12 is provided inside the first bracket 5. The rotating shaft 11 passes through the rotating bearing 12 and rotates inside the rotating bearing 12. A rotating disk 13 is provided on the side of the rotating plate 7 on one side of the second bracket 6 and is installed inside the second bracket 6. A third fixing bolt 14 is connected through the rotating plate 7 on one side of the second bracket 6, and one end of the third fixing bolt 14 passes through the rotating disk 13. The third fixing bolt 14 is used to fix the rotating disk 13 to the rotating plate 7. The rotating disk 13 is driven by the rotating cylinder 25, so that the rotating plate 7 rotates with the rotating disk 13.

[0033] Reference Figure 3 and Figure 4A fourth fixing bolt 20 is internally connected to the square box fixture 15, and a fourth fixing nut 21 is provided at the other end of the fourth fixing bolt 20. The fourth fixing nut 21 is installed on one side of the connecting plate 10. The fourth fixing bolt 20 and the fourth fixing nut 21 are threaded together and used to fix the square box fixture 15 to one side of the connecting plate 10. A fixing plate 22 is provided below the connection between the rotating plate 7 and the connecting plate 10, and a fifth fixing bolt 23 is internally connected to both ends of the fixing plate 22. The fixing plate 22 is used to further fix the rotating plate 7 and the connecting plate 10. The stop strips 18 are of different lengths on the top and bottom. A longer stop strip 18 is wrapped around the outside of the thick surface 16 of the fixture, and a shorter stop strip 18 is wrapped around the outside of the thin surface 17 of the fixture. The lengths of the stop strips 18 on the outside of the thick surface 16 and the thin surface 17 of the fixture are different. Users can distinguish the rotation direction of the square box fixture 15 according to the length of the stop strips 18, which effectively reduces the possibility of printing direction errors.

[0034] Working principle: First, during use, the rotary cylinder 25 is controlled to rotate the square box fixture 15 to a horizontal position. The operator observes the length of the retaining strip 18 on the outside of the thick side 16 and thin side 17 of the fixture to confirm that the direction is correct. Then, the square box to be printed is accurately fitted onto the outside of the square box fixture 15. Next, the air pump 27 controls the rotary cylinder 25 through the conduit 26, causing the rotating disk 13 inside the second bracket 6 to rotate, so that the rotating plate 7 follows the rotating disk 13. The rotating plate 7 on one side of the first bracket 5 rotates inside the rotating bearing 12 through the rotating shaft 11, causing the connecting plate 10 set between the rotating plates 7 to rotate, driving the square box fixture 15 to flip. Then, the printing mechanism prints on the top and bottom of the square box installed on the outside of the square box fixture 15. The printed square box is then removed by the operator and placed in the corresponding drying mechanism for drying, completing the production. When the square box fixture 15 rotates, the hollowed-out grooves 19 on both sides of the square box fixture 15 can effectively make the square box fixture 15 rotate smoothly. The fixing piece 22 provided below the connection between the rotating plate 7 and the connecting plate 10 can effectively improve the connection strength between the rotating plate 7 and the connecting plate 10.

[0035] Example 2

[0036] See Figure 7 , 8In this embodiment, the square box fixture 15 has a first positioning groove 151 and a second positioning groove 152 on both sides, with different widths. When fixing and printing the storage box with the front opening, since the upper and lower wall thicknesses of the box are different, the first positioning groove 151 and the second positioning groove 152 are designed to correspond to the thicknesses of the upper and lower wall thicknesses of the box. When the orientation is correct, the box can be inserted normally for printing; when the orientation is incorrect, the box gets stuck in the groove and cannot be inserted, reminding the operator of the incorrect orientation to prevent reverse placement, which would lead to incorrect printing orientation and ensure correct printing orientation.

[0037] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
