The actuating member 43 has an abutting portion 431 which can be driven by the driving member 41 to provide a biasing force against the feeding mechanism 20 of the casing 200. In the present embodiment, the driving member 41 is a rotating cylinder, and of course, it may be replaced by a driving member such as a motor. The actuating member 43 has a substantially "L"-shaped structure, and the bent portion of the "L"-shaped structure is curved, and the bent portion is an abutting portion 431, and the curved abutting portion 431 can avoid scratching the box. Body 200.

The second folding mechanism 50 is an inclined structure having an inclined portion 51 inclined with respect to the moving direction of the casing 200. The inclined portion 51 is away from the feeding mechanism 20 at one end of the first folding mechanism 40, and away from the first folding mechanism 40. One end is adjacent to the feeding mechanism 20, that is, the inclined portion 51 faces the feeding mechanism 20 and the first folding mechanism 40 and can provide the housing 200 with a thrust against the feeding mechanism 20. In the present embodiment, the second folding mechanism 50 is a bent rod-like structure, and the two ends thereof are fixed to the fixing frame 30. Of course, the second folding mechanism 50 of the inclined structure may also be a block structure having a slope inclined with respect to the feeding mechanism 20.

The angle between the first slope 611 and the second slope 631 is the angle B.

If the angle of inclination of the first inclined surface 611 and the second inclined surface 631 with respect to the receiving member 65 is too small, that is, the angle A is too large, the resistance to the housing 200 is excessively increased, and the housing 200 is prevented from moving with the feeding mechanism 20; The angle between the first inclined surface 611 and the second inclined surface 631 is too large, that is, the angle between the first inclined surface 611 and the second inclined surface 631 inclined with respect to the plane of the feeding mechanism 20 is too small, which may result in the opening of the casing 200. The fold is not complete. Therefore, in order to ensure that the box 200 smoothly passes through the third folding mechanism 60 and the opening is completely folded, the angle of the A angle ranges from 110° to 130°, that is, the first inclined surface 611 and the second inclined surface 631 are inclined with respect to the receiving member 65. °~70°, the angle of the B angle ranges from 40° to 80°.

Referring to FIG. 4 and FIG. 5 together, the sealing mechanism 70 includes a supporting body 71, a rubber cutting blade 72 fixed on the supporting body 71, a rubber wheel 73 pivoted on the supporting body 71, a first pressing wheel 74 and The second pressure roller 75. The rubber wheel 73 is wound with a tape 731, and the free end of the tape 731 passes through the rubber cutter 72 and is wound around the first pressure roller 74, and one end of the rubber cutter 72 abuts against the tape 731.

Referring to FIG. 1, the guide abutting member 80 is disposed on one side of the feeding mechanism 20 and parallel to the extending direction of the feeding mechanism 20. The guide abutting member 80 is a bent plate-like structure having an "L" shape in cross section, and includes a fixing plate 81 and a resisting plate 83. A fixing hole 81 is formed in the fixing plate 81, and the fixing plate 81 is fixed to the table 10 from the waist hole 811 by a fastener (not shown) such as a screw or the like. In the present embodiment, the abutting plate 83 is perpendicular to the support surface 11 of the table 10.

Referring to FIG. 6 , the box body 200 to be sealed is a quadrangular prism, and includes a box body 201 and a first hinge 202 and a second hinge 203 extending from the four edges of the opening of the box body 201 . Three hinges 204 and fourth hinges 205.

Referring to FIG. 1 , FIG. 2 and FIG. 6 , when the box body 200 is sealed by the box sealing device 100 , the box body 200 to be sealed passes through the first folding mechanism 40 and the second folding line along the feeding mechanism 20 . The pressing mechanism 50, the third folding mechanism 60, and the sealing mechanism 70, that is, the casing 200 are moved in the "X" direction.

The box body 200 to be sealed is placed at one end of the feeding mechanism 20 near the first folding mechanism 40, and one side of the box body 200 has been sealed against the abutting plate 83 of the guiding abutting member 80. The feeding mechanism 20 drives the box body 200 to move along the guiding abutting member 80. When the box body 200 does not pass the first folding mechanism 40, the actuating member 43 of the first folding mechanism 40 rotates away from one side of the feeding mechanism 20 for the box. The third hinge 204 of the body 200 can pass through the first folding mechanism 40. After the third hinge 204 of the casing 200 passes through the first folding mechanism 40, the third hinge 204 abuts against the inclined portion 51 of the second folding mechanism 50, and the inclined portion moves with the movement of the casing 200. 51 presses the third hinge 204 of the case 200. When the second folding mechanism 50 presses the third hinge 204 of the casing 200, the actuating member 43 of the first folding mechanism 40 rotates in the "Y" direction under the driving of the driving member 41. The abutting portion 431 of the actuating member 43 contacts the first hinge 202 of the casing 200 and presses the first hinge 202. During this process, the thrust force applied by the first folding mechanism 40 and the second folding mechanism 50 to the casing 200 is inclined with respect to the feeding mechanism 20, and the first folding mechanism 40 and the second folding mechanism 50 apply to the casing 200. The abutting thrust has a opposing component, and the first hinge 202 and the third hinge 204 of the casing 200 are folded toward each other.

Referring to FIG. 4 again, as the feeding mechanism 20 continues to move, the second hinge 203 and the fourth hinge 205 gradually enter the slot 601 of the third folding mechanism 60. The second hinge 203 is in contact with the first inclined surface 611 of the third folding mechanism 60, and the fourth hinge 205 is in contact with the second inclined surface 631 of the third folding mechanism 60. As the housing 200 moves, the second hinge 203 and the fourth hinge 205 slide along one of the first hinges 611 and the second slope 631, and the first slope 611 and the second slope 631 are aligned. The second hinge 203 and the fourth hinge 205 apply a thrust force that opposes and intersects the moving direction of the casing 200. Since the first inclined surface 611 and the second inclined surface 631 are away from the feeding mechanism 20 from one end of the second folding mechanism 50, the second hinge 203 and the fourth hinge 205 first form an angle, and then the first inclined surface 611 and the first The edge formed by the joint of the reference surface 613, the edge formed by the joint of the second inclined surface 631 and the second reference surface 633, and the first reference surface 613 and the second reference surface 633 are completely pressed together and are parallel to the third folding mechanism 60. Item 65. At this time, the first hinge 202, the second hinge 203, the third hinge 204, and the fourth hinge 205 of the casing 200 are all pressed together. The first hinge 202 and the third hinge 204 are first pressed together, and the second hinge 203 and the fourth hinge 205 are pressed together, so that they are finally at the end of the second hinge 203 and the fourth hinge 205. A gap extending in the "X" direction is formed.

As the feeding body 20 continues to move and contacts the first pressing wheel 74 of the sealing mechanism 70, the tape 731 wound on the first pressing wheel 74 is pressed by the first pressing wheel 74 to the second hinge 203 and The end of the fourth hinge 205. As the case 200 moves, the ends of the second hinge 203 and the fourth hinge 205 are joined by the tape 731 and the gap formed therebetween is shielded by the tape 731. When the case 200 approaches the one end of the first hinge 202 and passes through the rubber cutting blade 72, the rubber cutting blade 72 cuts the tape 731. One end of the tape 731 which is grown on the casing 200 can be pressed and attached to the casing 200 by hand. When the casing 200 passes the second pressure roller 75, the second pressure roller 75 presses the tape 731 attached to the casing 200 to firmly adhere the tape 731 to the casing 200.

When the entire casing 200 passes through the sealing mechanism 70, the casing sealing device 100 completes the sealing of the casing 200.

In the box sealing device 100, the first folding mechanism 40, the second folding mechanism 50, and the third folding mechanism 60 sequentially act on the casing 200 to realize the first hinge 202 of the casing 200. The hinge 203, the third hinge 204, and the fourth hinge 205 are folded with respect to the case main body 201. The casing 200 is provided with one of the first hinge 202, the second hinge 203, the third hinge 204, and the fourth hinge 205 by the sealing mechanism 70 to seal the casing 200. By using the box sealing device 100, the automatic sealing of the opening of the box 200 can be realized, and the box 200 can be loaded and unloaded directly to the feeding mechanism 20, which saves manpower, reduces the labor intensity of the operator, and improves the efficiency. . The plurality of mechanisms of the box sealing device 100 cooperate with each other to programmatically seal the box 200, and the standard is unified, which ensures a good overall appearance.

In the box sealing device 100, the fixing plate 81 of the guiding abutting member 80 is provided with a waist hole 811, and the distance between the guiding abutting member 80 and the feeding mechanism 20 can be adjusted to adapt to the housing 200 of different sizes, and the versatility is good.

It can be understood that the fixing frame 30 can be omitted, and the first folding mechanism 40 and the second folding mechanism 50 can be directly fixed to the table 10.

The first inclined surface 611 and the second inclined surface 631 may not intersect, and the two together with the receiving member 65 form a trapezoidal groove with the receiving member 65 as a base, that is, a distance between the first wedge 61 and the second wedge 63.

The degree of inclination of the first inclined surface 611 and the second inclined surface 631 of the third folding mechanism 60 with respect to the receiving member 65 may be different.

Referring to FIG. 7, the structure of the box sealing device 300 in the second embodiment is substantially the same as the structure of the box sealing device 100 (see FIG. 1) in the first embodiment. The difference is that in the second embodiment, the first folding mechanism 301 and the second folding mechanism 302 both use the push rod structure driven by the cylinder to fold the box 200. The feeding mechanism 303 includes a driving motor 3031, a screw rod 3032, and a carrying table 3033. The casing 200 can be placed on the carrying platform 3033, and the driving motor 3031 drives the screw 3032 to rotate, thereby driving the loading platform 3033 to move along the screw 3032.
