[0028] When the packaging box enters the feeding conveyor, the packaging box cover is clamped between the pressure strip 202 and the feeding conveyor, and the side of the packaging box away from the cover is close to the first limiting strip 201, so that the packaging box is fixed on the feeding conveyor for stable transportation and the packaging box cover is prevented from jumping during transportation.

[0029] In some embodiments, the automatic folding box packaging machine of the embodiment of the present application further includes a feeding mechanism 3, the discharge port of the feeding mechanism 3 is arranged directly above the feeding conveyor belt and faces the feeding conveyor belt. The positioning mechanism 2 further includes a blocking arm 203 and a positioning arm 204, and the tops of the blocking arm 203 and the positioning arm 204 are provided with positioning plates; the blocking arm 203 and the positioning arm 204 are arranged beside the feeding conveyor belt; the blocking arm 203 is located on the side of the discharge port of the feeding mechanism 3 close to the front end of the feeding conveyor belt, and the positioning arm 204 is located on the side of the discharge port of the feeding mechanism 3 close to the front end of the feeding conveyor belt; the output ends of the blocking arm 203 and the positioning arm 204 face the feeding conveyor belt. When the packaging box enters the feeding conveyor, it is sent to the bottom of the discharge port of the feeding mechanism 3 by the feeding conveyor; then the blocking arm 203 and the positioning arm 204 are actuated to extend the positioning plate to the feeding conveyor; the positioning arm 204 blocks the packaging box below the discharge port for feeding, and the blocking arm 203 blocks the packaging box behind to prevent the packaging box behind from colliding with the packaging box being fed and causing interference. Furthermore, the feeding mechanism 3 may have multiple discharge ports, in which case the number of positioning arms 204 is equal to the number of discharge ports. In some embodiments, the first limiting strip 201 or the first auxiliary limiting strip 201a is provided with a passing slot corresponding to the blocking arm 203 and the positioning arm 204, respectively, and the passing slot is used for the blocking arm 203 and the positioning arm 204 to pass through.

[0030] See also Figure 3 The folding mechanism 4 includes a second limiting strip 401, a box pressing strip 402, a cover lifting plate 403 and a cover folding plate 404. The second limiting strip 401 is arranged above the folding conveyor belt, and the second limiting strip 401 is arranged at the rear end of the first limiting strip 201. The distance between the second limiting strip 401 and the surface of the folding conveyor belt is less than the height of the packaging box. The box pressing strip 402 is arranged above the folding conveyor belt and is parallel to the second limiting strip 401. The distance between the box pressing strip 402 and the surface of the folding conveyor belt is greater than or equal to the height of the packaging box, and the distance between the box pressing strip 402 and the second limiting strip 401 is less than the width of the packaging box.

[0031] The cover lifting plate 403 is arranged at the beginning of the folding box conveyor belt, beside the conveyor belt 1 or above the folding box conveyor belt, and the distance between the cover lifting plate 403 and the second limiting strip 401 is greater than the width of the packaging box, and less than the sum of the width of the packaging box and the width of the packaging box cover. The height of the cover lifting plate 403 gradually increases from the front end to the rear end, and further, the height of the front end of the cover lifting plate 403 is lower than the height of the lower surface of the box cover when the packaging box is opened.

[0032] The folding cover plate 404 is arranged beside the conveyor belt 1 or on the folding box conveyor belt, and specifically, the folding cover plate 404 is located on the extension line of the lifting cover plate 403. The height of the folding cover plate 404 gradually increases from the front end to the rear end, and the front end height of the folding cover plate 404 is less than or equal to the rear end height of the lifting cover plate 403; the distance between the folding cover plate 404 and the second limiting strip 401 gradually decreases, and the rear end of the folding cover plate 404 extends and exceeds the rear end of the box pressing strip 402, and the distance between the rear end of the folding cover plate 404 and the second limiting strip 401 is less than the width of the packaging box; when the distance between the folding cover plate 404 and the second limiting strip 401 is reduced to the width of the packaging box, the height of the folding cover plate 404 is higher than the height of the packaging box.

[0033] After the packaging box is loaded on the feeding conveyor, it is fed into the folding conveyor along the first limiting strip 201 with the assistance of the positioning mechanism 2; the positioning mechanism 2 can ensure that the packaging box is fed into the folding conveyor along the predetermined route. After the packaging box enters the folding conveyor, the packaging box is fixed on the folding conveyor by the second limiting strip 401 and the box pressing strip 402. When the box cover of the packaging box passes through the lifting cover plate 403, the lifted cover plate 403 is gradually lifted. When the box cover of the packaging box passes through the folding cover plate 404, the folding cover plate 404 gradually lifts the box cover and pushes it inward until the box cover is closed.

[0034] Furthermore, the front end of the second limiting strip 401 is bent toward the outside of the box folding conveyor belt, and the front end of the box pressing strip 402 is bifurcated into two strips, one of which is bent upward, and the other is bent away from the second limiting strip 401. The bending of the second limiting strip 401 and the box pressing strip 402 is conducive to guiding the box into a predetermined route.

[0035] In some embodiments, the distance between the top of the bent portion at the front end of the second limiting strip 401 and the central axis of the conveyor belt 1 is greater than the distance between the first limiting strip 201 and the central axis of the conveyor belt 1; the distance between the straight section of the second limiting strip 401 and the central axis of the conveyor belt 1 is less than the distance between the first limiting strip 201 and the central axis of the conveyor belt 1; the cover lifting plate 403 is arranged beside the conveyor belt 1. Through the above arrangement, when the packaging box enters the folding box conveyor belt from the feeding conveyor belt, the packaging box is pushed along the second limiting strip 401 until the cover of the packaging box is exposed from the conveyor belt, so that the cover lifting plate 403 arranged beside the conveyor belt 1 can lift the cover of the packaging box.

[0036] See also Figure 4In some embodiments, the automatic folding box packaging machine of the embodiment of the present application further includes a box pressing mechanism 5, and the conveyor belt 1 further includes a lower box pressing conveyor belt; the box pressing mechanism 5 includes an upper box pressing conveyor belt. The lower box pressing conveyor belt is arranged at the rear end of the folding box conveyor belt, and the upper box pressing conveyor belt is arranged above the lower box pressing conveyor belt. A box pressing gap is formed between the upper box pressing conveyor belt and the lower box pressing conveyor belt, and the box pressing gap is set according to the height of the packaging box after the box cover is closed. The upper box pressing conveyor belt is parallel to the lower box pressing conveyor belt and directly faces the lower box pressing conveyor belt, and the transmission direction of the upper box pressing conveyor belt and the lower box pressing conveyor belt are the same. Further, the box pressing mechanism 5 also includes a third limiting bar and a fourth limiting bar, and the third limiting bar and the fourth limiting bar are arranged above the lower box pressing conveyor belt and along the conveying direction of the lower box pressing conveyor belt. The distance between the third limiting bar, the fourth limiting bar and the surface of the feeding conveyor belt is less than the height of the packaging box, and the distance between the third limiting bar and the fourth limiting bar is equal to the width of the packaging box.

[0037] After the packaging box is covered with a box cover on the box folding conveyor belt, it is sent to the box pressing mechanism 5. The packaging box is pressed tightly against the box cover by sending the packaging box to the lower box pressing conveyor belt and the upper box pressing conveyor belt. The third limiting strip and the fourth limiting strip play a role of auxiliary fixing.

[0038] The automatic box folding packaging machine of the embodiment of the present application lifts the box cover of the packaging box by the cover lifting plate 403, and gradually closes the box cover with the cover folding plate 404. Compared with the prior art, the automatic box folding packaging machine of the embodiment of the present application can automatically close the box cover of the packaging box, and does not need to use a mechanical arm to close the cover during the box folding process, and has a simple structure and high packaging efficiency.

[0039] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent.
