[0028] See also Figure 1-Figure 4 As shown, the present invention provides a metal mask plate packaging box for packaging a metal mask plate, wherein the metal mask plate includes a graphic area in the middle and a test area at the edge, and includes a bottom plate 1, a top plate 2 and a connecting plate 3, wherein the two sides of the connecting plate 3 are respectively connected to the bottom plate 1 and the top plate 2, a first cross-linking groove 4 is provided between one side of the connecting plate 3 and the inner side of the top plate 2, a second cross-linking groove 5 is provided between the other side of the connecting plate 3 and the inner side of the bottom plate 1, and a receiving groove 1a for protecting the graphic area of ​​the metal mask plate is provided on the bottom plate 1.

[0029] By placing multiple metal mask plates on the accommodating groove 1a with both ends exposed outside the accommodating groove 1a, a large number of metal mask plates can be stored in a small space, which is easy to carry. After vacuum sealing, the problem of the metal mask plates being easily damaged during long-distance transportation is solved. The bottom plate 1 and the top plate 3 fit tightly together, which can prevent the metal mask plates from rusting during long-term storage.

[0030] Specifically, the bottom plate 1 is provided with a directional mark 1c for indicating the placement direction of the metal mask plate, thereby improving packaging efficiency. The bottom plate 1, the top plate 2 and the connecting plate 3 are all hollow plastic plates. The outsides of the bottom plate 1 and the top plate 2 are both provided with chamfers 10, so that when the packaging box is vacuum-sealed, the outer plastic sealing bag and the packaging box are closely attached, thereby further improving the vacuum sealing effect.

[0031] Specifically, the connecting plate 3 is a triangular plate, and the first cross-linking groove 4 and the second cross-linking groove 5 are both triangular grooves.

[0032] Preferably, elastic support components 6 are provided at both ends of the receiving groove 1a, and the elastic support components 6 include two limit bars 61, a support bar 62, and an elastic bar 63. The two limit bars 61 are symmetrically arranged at one end of the receiving groove 1a, and one end of the limit bar 61 is rotatably arranged in the receiving groove 1a, and the two ends of the support bar 62 are respectively hinged to the other ends of the two limit bars 61, and a curved elastic bar 63 is provided between the support bar 62 and the end wall of the receiving groove 1a. Specifically, the receiving groove 1a is a rectangular groove, and the four corners of the top of the receiving groove 1a are provided with rounded corners, and a rotating shaft 11 is installed between the rounded corner and the receiving groove 1a, and one end of the limit bar 61 is installed on the rotating shaft 11. The elastic bar 63 is a wavy elastic bar.

[0033] By providing the elastic support assembly 6, the test area of ​​the metal mask plate is stably clamped on the two support plates 62 to prevent the metal mask plate from moving in the accommodating groove 1a during transportation and handling, and the elastic strip 63 can play a shock-absorbing role to enhance the pressure-bearing capacity.

[0034] Specifically, the support strip 62 and the elastic strip 63 are extended along the width direction of the receiving groove 1 a , and the limiting strip 61 is inclined.

[0035] Preferably, a bonding groove 1b is provided on the bottom plate 1, and a flexible bonding tape 7 is correspondingly provided on the top plate 2, and the flexible bonding tape 7 is bonded and matched with the bonding groove 1b.

[0036] Specifically, a plurality of adhesive tapes 8 are spaced apart in the bonding groove 1 b , and the flexible bonding tape 7 is bonded to the adhesive tapes 8 .

[0037] Specifically, pull blocks 9 are respectively disposed on the outer sides of the bottom plate 1 and the top plate 2 , and the two pull blocks 9 are staggered.

[0038] The flexible bonding tape 7 is used to bond with the bonding groove 1b, which can improve the sealing performance of the packaging box; by providing the adhesive tape 8 and the pull block 9, it is convenient to open the packaging box and take out the metal mask plate from the accommodating groove 1a.

[0039] When making a packaging box, align and stack two hollow plastic plates with a thickness of 5 mm. Determine the area of ​​the hollow plastic plate according to the size and number of metal mask plates to be placed. Heat-melt seal the holes around the stacked hollow plastic plates, and heat-melt press out the chamfers. Then cut the middle of the hollow plastic plate, seal the holes by heat-melt, and heat-melt press out the chamfers to form a triangular plate and a triangular groove. Dig out a receiving groove 1a and a fitting groove 1b at one end of the hollow plastic plate. Finally, install an elastic support component 6 in the receiving groove 1a, paste an adhesive tape 8 in the fitting groove 1b, install a flexible adhesive tape 7 at the other end of the hollow plastic plate, and install a pull block 9 on the outside of the hollow plastic plate.

[0040] Figure 4A side view of a packaging box after hot-melt grooves are cut in two hollow plastic plates.

[0041] During packaging, multiple metal mask plates are placed on the upper surface of the top plate 2, and then the receiving groove 1a of the bottom plate 1 is covered on the metal mask plate. The receiving groove 1a does not touch the pattern area of ​​the metal mask plate, and the metal mask plate is clamped at both ends of the receiving groove 1a. Finally, the closed packaging box is vacuumed and plastic-sealed to isolate oxygen and water to prevent the metal mask plate in the packaging box from rusting.
