Description

Technical Field

[0001] The present application relates to the field of PVC packaging boxes, and in particular to a hole-opening device for a PVC packaging box. Background Art

[0002] PVC packaging boxes are a common packaging material, usually used to package various commodities or gifts. PVC (polyvinyl chloride) is a plastic material with the characteristics of high transparency, durability and good softness. This makes PVC packaging boxes very suitable for displaying products. In order to increase the display and convenience of the product while maintaining the integrity of the packaging, holes are made on the outer surface of the packaging box.

[0003] PVC packaging boxes are generally punched. During the punching process, the punch head will act on the upper surface of the packaging box, but the downward movement of the punch head will produce a large impact force. When the punch head acts on the packaging box to complete the punching, there will still be a certain impact inertia, which may cause certain impact damage to the packaging box as a whole, causing a certain concave bend at the edge of the opening, reducing the overall opening effect of the packaging box.

[0004] In view of the above-mentioned related technologies, the inventor believes that when punching holes in PVC packaging boxes, there is a defect that the edge of the hole is sunken by the punching head. Therefore, a PVC packaging box hole punching device is proposed to solve the above problem. Utility Model Content

[0008] Preferably, the supporting mechanism includes a fixed support plate, which is symmetrically welded to the side edges of the upper surface of the supporting base plate, and a fixed rod is symmetrically fixed between the two fixed support plates. Movable blocks are sleeved on the side edges of the outer surface of the fixed rod, and a threaded rod is threadedly connected to the middle part of the bottom end of the movable block, and a movable support plate is rotatably installed on the upper surface of the threaded rod through the movable block.

[0009] Preferably, the outer diameter of the movable rod is smaller than the inner diameter of the top opening of the hollow tube, and the hollow tube and the movable rod are coupled to each other.

[0010] Preferably, a circular hole is symmetrically opened through one side of the movable block, the outer diameter of the fixing rod is smaller than the inner diameter of the circular hole, and the fixing rod and the circular hole are adapted to each other.

[0018] The following is combined with Figure 1-3 This application is described in further detail.

[0019] The present application embodiment discloses a PVC packaging box hole opening device. Figure 1-3 A PVC packaging box hole opening device comprises a supporting base plate 1, a punching base 2 is fixedly installed at the middle of the top of the supporting base plate 1, a supporting frame 3 is fixedly connected to the upper surface of the supporting base plate 1 near the punching base 2, a movable part 4 is movably installed inside the supporting frame 3, a punching head 5 is fixedly connected to the middle of the bottom end of the movable part 4, and fixed baffles 6 are welded at the two side edges of the movable part 4 extending to the outside of the supporting frame 3, hollow tubes 7 are symmetrically fixedly connected to the two side edges of the supporting base plate 1 near the supporting frame 3, a spring 8 is installed at the bottom end of the inner wall of the hollow tube 7, and a movable rod 9 is movably installed above the spring 8, the outer diameter of the movable rod 9 is smaller than the inner diameter of the top opening of the hollow tube 7, the hollow tube 7 and the movable rod 9 are coupled to each other, and the top of the movable rod 9 extends to the top of the hollow tube 7 and a supporting plate 10 is welded thereon, and a supporting mechanism is also provided on the upper surface of the supporting base plate 1 for supporting the two side edges of the packaging box.

[0020] By placing the packaging box on the upper surface of the punching base 2, the movable part 4 moves downward along the inside of the support frame 3, and the punching head 5 acts on the packaging box to punch holes. After the punching is completed, the fixed baffle 6 moves synchronously with the movable part 4 under the action of inertia, and then abuts against the upper surface of the support plate 10, so that the fixed baffle 6 pushes the support plate 10 to move downward, and the movable rod 9 slides into the hollow tube 7 to compress the spring 8, so that the spring 8 cooperates with the movable rod 9 to buffer and support the movable part 4, which reflects the problem of the large inertia of the movable part 4 driving the punching head 5 to move downward.

[0021] Reference Figure 1 and Figure 2 The supporting mechanism includes a fixed support plate 11, which is symmetrically welded at the two side edges of the upper surface of the supporting base plate 1, and a fixed rod 12 is symmetrically fixed between the two fixed support plates 11. The two side edges of the outer surface of the fixed rod 12 are sleeved with movable blocks 13, and one side edge of the movable block 13 is symmetrically penetrated with circular holes, the outer diameter of the fixed rod 12 is smaller than the inner diameter of the circular hole, and the fixed rod 12 and the circular hole are adapted to each other. A threaded rod 14 is threadedly connected to the middle part of the bottom end of the movable block 13, and a movable support plate 15 is rotatably installed on the upper surface of the threaded rod 14 through the movable block 13. A through hole is symmetrically penetrated at the top edge of the movable block 13, and a connecting rod 16 is symmetrically welded at the bottom edge of the movable support plate 15. The outer diameter of the connecting rod 16 is smaller than the inner diameter of the through hole, and the connecting rod 16 and the through hole are embedded with each other.

[0022] By making the movable block 13 move along the outer surface of the fixed rod 12, adjusting the movable block 13 to move close to the edges of both sides of the packaging box, rotating the threaded rod 14 to push the movable support plate 15 to move up and down, and at the same time making the connecting rod 16 move synchronously along the outer surface of the movable block 13, the movable support plate 15 can be moved to abut against the edges of both sides of the bottom end of the packaging box, thereby keeping the packaging box as a whole in a flat state, which reflects the supporting effect of the movable support plate 15 on the edges of both sides of the packaging box.

[0023] The implementation principle of the PVC packaging box hole-punching device of the embodiment of the present application is as follows: by placing the packaging box on the upper surface of the punching base 2, the movable block 13 is moved along the outer surface of the fixed rod 12, the movable block 13 is adjusted to move close to the edges of both sides of the packaging box, and the threaded rod 14 is rotated to push the movable support plate 15 to move up and down, and at the same time, the connecting rod 16 is synchronously moved along the outer surface of the movable block 13, so that the movable support plate 15 is movable and abuts against the edges of both sides of the bottom of the packaging box, thereby keeping the packaging box as a whole in a flat overall state, solving the problem that the two sides of the packaging box naturally droop and cause the middle position to bend upward, so that the movable part 4 is moved along the inner side of the support frame 3. It moves downward, so that the punching head 5 acts on the packaging box to punch holes. After the punching is completed, the fixed baffle 6 moves synchronously with the movable part 4 under the action of inertia, and then abuts against the upper surface of the support plate 10, so that the fixed baffle 6 pushes the support plate 10 to move downward, and the movable rod 9 slides into the hollow tube 7 to compress the spring 8, so that the spring 8 cooperates with the movable rod 9 to buffer and support the movable part 4. Compared with the prior art, this solution has the effect of facilitating the buffering and support of the movable part 4 after punching, reduces the inertial impact force of the packaging box after punching, and solves the problem of compressed depression and bending at the punching edge of the packaging box.
