[0026] Please see Figure 1 and Figure 2This utility model provides an embodiment of a fully automatic carton sealing machine, comprising a frame 1, a linkage shaft 2, and a pre-opening swing arm 5. The linkage shaft 2 is fixedly installed on the outer side of the frame 1. A pre-opening bushing 3 is fixedly installed at the top of the outer wall of the frame 1. A pre-opening rotating shaft 4 is rotatably fitted inside the pre-opening bushing 3. A pre-opening swing arm 5 is fixedly installed at the end of the pre-opening rotating shaft 4. A pre-opening lever 6 is vertically fixedly installed at the end of the pre-opening swing arm 5. The lower end of the pre-opening lever 6 extends to the top of the outer wall of the arc-tooth synchronous belt 7. A first linkage gear 8 is fixedly installed at one end of the outer side of the pre-opening rotating shaft 4. A synchronous belt is provided on the outer wall of the linkage shaft 2 to connect to the drive shaft 25. A crank rocker arm 26 is fixedly connected to the outer periphery of the drive shaft 25. A folding tongue block 27 is fixedly installed at one end of the rocker arm 26.

[0027] Specifically, the motor drives the linkage shaft 2 to rotate through the flexible coupling, and the linkage shaft 2 drives the first linkage gear 8 to rotate through the outer peripheral drive gear. The first linkage gear 8 drives the pre-opening rotating shaft 4 to rotate within the brass bushing of the pre-opening bushing 3. The linkage shaft 2 drives the drive shaft 25 to rotate synchronously through the synchronous pulley at the end.

[0028] The pre-opening rotating shaft 4 drives the pre-opening swing arm 5 to reciprocate around the axis of the pre-opening rotating shaft 4. The pre-opening swing arm 5 drives the pre-opening lever 6 to make an arc motion. When the carton is positioned by the side baffle of the arc-tooth synchronous belt 7 and conveyed to the area below the pre-opening lever 6, the arc section at the lower end of the pre-opening lever 6 just contacts the right side tongue of the carton. The swing arm swings to the right to open the side tongue, which can avoid the problem of material jamming when pushing material due to the side tongue not opening in traditional carton sealing machines.

[0029] When the drive shaft 25 rotates, it drives the crank of the crank rocker arm 26 to make a circular motion. The crank pulls the rocker arm to reciprocate around the central pin through the fisheye bearing. The rocker arm drives the folding tongue block 27 to move synchronously. When the cardboard box that has passed the pre-opened side tongue is conveyed to the area below the folding tongue block 27, the wedge-shaped end of the folding tongue block 27 contacts the large tongue of the cardboard box. As the rocker arm swings, it presses down on the large tongue and bends it 90° along the preset crease of the cardboard box. The folding tongue block 27 disengages from the cardboard box when the rocker arm returns to its original position.

[0030] The arc-tooth synchronous belt 7 operates continuously under the drive of the transmission shaft, and the pre-opening side tongue and the folding large tongue are mechanically synchronized through the linkage shaft 2.

[0031] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4 The present invention provides an embodiment of a fully automatic carton sealing machine, wherein an adjusting wheel 18 is fixedly installed at one end of the bidirectional screw 17, and a positioning ring 24 is welded to the middle of the bidirectional screw 17; a sliding groove is opened on the inner wall side of the frame 1 and a first slider 15 and a second slider 21 are embedded therein; a nut seat 16 is welded to the outer wall side of the first slider 15, and the bidirectional screw 17 passes through the nut seat 16; the bidirectional screw 17 is fixedly installed on the outer wall side of the frame 1.

[0032] Specifically, when changing to a cardboard box of different lengths, first loosen the anti-loosening nut at the waist-shaped hole of the bracket 19, adjust the front and rear position of the bracket 19 according to the width of the cardboard box, so that the vertical projection of the pre-opening guide rod 20 and the folding side guide rod 22 just covers the side tongue of the cardboard box, and fix the bracket with the anti-loosening nut after adjustment.

[0033] Rotating the adjusting wheel 18 causes the bidirectional screw 17 to rotate. Since the threads at both ends of the bidirectional screw 17 rotate in opposite directions, the left nut seat 16 drives the second slider 21 to move to the left along the T-shaped slide groove, while the right nut seat 16 drives the first slider 15 to move to the right along the slide groove, achieving synchronous reverse movement of the two sliders. The distance between the pre-opening guide rod 20 and the folding side guide rod 22 is adjusted to match the length of the cardboard box.

[0034] After startup, the cardboard box is conveyed to the pre-opening side tongue station by the arc toothed synchronous belt 7. The pre-opening lever 6 opens the right side tongue of the cardboard box by 90°, and the side tongue contacts the pre-opening guide rod 20, keeping the side tongue in the open state to prevent the side tongue from closing due to the elastic rebound of the cardboard. The folding lever pushes the left side tongue of the cardboard box to the left, and at the same time the folding guide rod 22 guides the side tongue to bend inward to avoid folding deviation and wrinkles. The right side tongue bends inward synchronously under the obstruction of the synchronous belt side baffle.

[0035] Please see Figure 1 , Figure 2 and Figure 3 The present invention provides an embodiment of a fully automatic paper box sealing machine, wherein one end of a linkage rod 9 is hinged to the middle of the pre-opening swing rod 5, and the other end of the linkage rod 9 is hinged to the middle of the folding side swing rod 10, and the first linkage gear 8 meshes with the outer periphery of the linkage shaft 2;

[0036] One end of the folding rocker arm 10 is fixedly installed with the end of the folding rotating shaft 11, and the other end of the folding rocker arm 10 is vertically fixedly installed with the folding lever 12. The folding lever 12 is opposite to the pre-opening lever 6. One end of the folding rotating shaft 11 is fixedly installed with the second linkage gear 13, and the folding rotating shaft 11 is rotatably fitted inside the folding bushing 14. The tension wheel 23 meshes between the second linkage gear 13 and the first linkage gear 8.

[0037] Specifically, the motor is started, and the motor drives the linkage shaft 2 to rotate through the coupling. The drive gear of the linkage shaft 2 drives the first linkage gear 8 to rotate, and the first linkage gear 8 drives the pre-opening rotating shaft 4 to rotate. The pre-opening rotating shaft 4 drives the pre-opening rocker arm 5 to swing around the axis of the pre-opening rotating shaft 4. The first linkage gear 8 drives the tension wheel 23 to rotate, and the tension wheel 23 drives the second linkage gear 13 to rotate. The second linkage gear 13 drives the folding rotating shaft 11 to rotate within the brass bushing of the folding bushing 14, providing auxiliary driving force for the folding rocker arm 10.

[0038] When the pre-opening swing arm 5 swings, the hinge hole in the middle pulls the folding side swing arm 10 to swing around the axis of the folding side rotation axis 11 through the linkage rod 9. The transmission action of the linkage rod 9 makes the swing direction of the pre-opening swing arm and the folding side swing arm opposite, so as to achieve coordinated action.

[0039] The cardboard box is conveyed to the area below the pre-opening lever 6. The pre-opening swing lever 5 drives the pre-opening lever 6 to swing to the right. The arc section at the lower end of the lever contacts the right side tongue of the cardboard box, opening the side tongue by 90°. The folding swing lever 10 drives the folding lever 12 to swing to the left to avoid interference with the pre-opening.

[0040] When the cardboard box reaches below the folding lever 12, the pre-opening swing lever 5 swings to the left, and the folding lever 10 drives the folding lever 12 to swing to the right. The lower end of the lever contacts the left side tongue of the cardboard box, bending the side tongue inward by 90°.

[0041] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4 This utility model provides an embodiment of a fully automatic paper box sealing machine. A groove is formed on the inner wall of the frame 1, into which a first slider 15 and a second slider 21 are embedded. A nut seat 16 is welded to the outer wall of the first slider 15, and a bidirectional screw 17 passes through the nut seat 16. The bidirectional screw 17 is fixedly installed on the outer wall of the frame 1. A bracket 19 is fixedly installed on the outer wall of the first slider 15, and a pre-opening guide rod 20 is fixedly installed at the top of the outer wall of the bracket 19. A folding guide rod 22 is fixedly installed on the outer wall of the second slider 21.

[0042] Specifically, by rotating the adjusting wheel 18, the bidirectional screw 17 rotates and drives the first slider 15 and the second slider 21 to move in opposite directions synchronously. By aligning the scale plate with the ruler, the distance between the pre-opening guide rod 20 and the folding guide rod 22 is adjusted to be consistent with the length of the cardboard box.

[0043] The cardboard box is conveyed to the pre-opening side tongue station by the arc toothed synchronous belt 7. The pre-opening lever 6 opens the right side tongue by 90°, and the side tongue contacts the pre-opening guide rod 20. The polytetrafluoroethylene sleeve on the surface of the pre-opening guide rod 20 rotates freely under the push of the side tongue, changing sliding friction into rolling friction and avoiding scratching the surface of the cardboard box. The dustproof scraper on the slider head can scrape off dust and paper scraps in the groove.

[0044] Working principle: After startup, the arc tooth synchronous belt transports the paper box to be sealed. When the paper box is transported to the pre-opening side tongue station, the pre-opening rotating shaft drives the pre-opening swing arm to swing under the drive of the linkage shaft, so that the pre-opening lever pushes the paper box side tongue outward. At the same time, the pre-opening guide rod helps to keep the side tongue open and avoid the elastic rebound of the paperboard.

[0045] The cardboard box is conveyed to the side tongue folding station. Under the transmission of the linkage rod, the side folding swing rod and the pre-opening swing rod swing in opposite directions and synchronously. The side folding lever pushes the pre-opened side tongue inward, and the side folding guide rod guides the side tongue to bend along the fold line.

[0046] The crank rocker drives the folding tongue block to press down on the large tongue of the cardboard box, causing it to bend along the crease. The inclined baffle assists in ensuring the accuracy of the bending angle of the large tongue.

[0047] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
