Description

Technical Field

[0001] The present invention relates to the technical field of packaging box sealing, and in particular to a box sealing machine for automatically installing adhesive tape. Background Art

[0002] A carton sealer is a commonly used packaging machine, primarily used for sealing cartons or boxes. Suitable for standalone operation or in conjunction with a carton opener or packer to form an automated packaging line, it uses BOPP adhesive tape (sealing tape) to seal cartons, simultaneously sealing both the top and bottom surfaces. It boasts fast packaging speed, high efficiency, and an aesthetically pleasing appearance. The carton sealer first clamps the carton with a belt, then uses a height-measuring wheel to measure the carton's height, adjusts the sealer's movement, and finally seals the carton with tape.

[0003] Existing carton sealing machines have many technical defects when in use. First, the tape roll on the machine movement needs to be manually threaded when it is used for the first time so that the tape can be fed around multiple sets of guide rollers, but manual threading is time-consuming and labor-intensive, a large amount of tape is wasted, and it is easy to cut your hands with the cutter at the bottom; second, the pressure plate on the machine movement is used to guide and correct the tape on the front pressure wheel, but since the pressure plate used in daily life is made of metal, when the tape is tightened for sealing, the edge of the tape is easily deformed and bent by the pressure plate, reducing the guiding and correcting effects, resulting in wrinkles on the tape at the sealing position; third, the current carton sealing machine uses guide wheels to guide the linear sealing movement of the packaging box. Due to the large number of guide wheels, they are prone to wear and damage (heavy objects are usually placed in the packaging box), increasing the friction with the bottom of the packaging box, resulting in frequent equipment shutdowns.

[0004] In summary, considering that the existing facilities cannot meet the work requirements, we propose a carton sealing machine that automatically installs tape. Summary of the Invention

[0018] The present invention provides an improved carton sealing machine for automatically installing adhesive tape, which has the following significant improvements and advantages compared to the prior art:

[0019] Start the small servo motor, and the rotating shaft drives the traveling gear to move counterclockwise, driving the entire positioning circular seat to move downward along the curved motion track. The stretching roller pulls the tape on the tape roll and slowly leads it out, passing through the first conduction wheel and the second conduction wheel in turn, and wraps the tape around the local position of the guide wheel to form a conduction state until it moves to the lower end of the curved motion track, achieving the purpose of automatically threading the tape, saving time and effort. Then manually turn the stretching roller and use a fine blade to automatically cut the tape to ensure that the tape cut is smooth and there are no pulling wrinkles.

[0020] Start the small drive motor, and after a series of transmissions, the horizontal section of the L-shaped suction tube rotates around the sealing bearing. The tube mouth of the L-shaped suction tube makes a circular motion and moves to a group of air flow channel positions closest to the tape, so that the tube mouth and the curved sealing joint are sealed and fitted. Start the small suction pump to generate suction, and use the suction force of several groups of tape adsorption holes to adsorb the tape at the lower end of the transmission chamber onto the wheel surface of the front pressure wheel to ensure that the two are fully fitted, thereby solving the problem of the tape being offset when it is initially pressed due to a gap or misalignment between the tape and the front pressure wheel, and improving the sealing quality.

[0021] With the help of the power of the movable seat, the two groups of corrugated telescopic airbags contact the extrusion blocks respectively as the front pressure wheel moves, compressing the corrugated telescopic airbags. The air inside the airbags is injected into the airbag seat through the connecting tube, causing the two groups of airbag columns on the airbag seat to expand and thicken after taking in air, thereby narrowing the flexible gap, improving the limiting effect on the edge of the tape, avoiding the deviation of the tape, and increasing its tension, taking into account the flexibility and limiting properties of the tape pressing piece, significantly improving the tape pressing effect, and replacing the metal tape pressing piece.

[0022] Start the servo motor to drive one of the groups of adjustment plates to rotate, and connect the transmission in sequence through the sprocket and small chain on the short shaft, so that several groups of adjustment plates rotate synchronously in the same direction, so that the anti-slip grooves of each group of adjustment plates 90 contact the bottom of the packaging box and slightly lift the cardboard to enhance the contact force. The two groups of clamping belts synchronously clamp the packaging box and move it straight to the right to seal the box. The follow-up slide slides with low resistance on the two groups of resistance-free guide slides, and moves straight to the right along with the packaging box, thereby increasing the sliding guide performance of the bottom of the packaging box and solving the problem of equipment shutdown caused by wear of the guide wheels.

[0041] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention. Example 1

[0042] like Figures 1-14 As shown, this embodiment provides a carton sealing machine for automatically installing tape, including a machine base 1, and box-clamping conveyors 2 are symmetrically and movably arranged on both sides of the upper end surface of the machine base 1. The box-clamping conveyor 2 is driven by a cylinder structure, and a clamping belt 3 acting on the packaging box is arranged inside the box-clamping conveyor 2. Several groups of No. 1 guide wheels 4 are equidistantly arranged in the middle position of the upper end surface of the machine base 1, and several groups of No. 2 guide wheels 5 are symmetrically arranged on the upper end surface of the machine base 1 and on the inner side of the box-clamping conveyor 2. The number and position of the guide wheels are set according to actual conditions.

[0043] Furthermore, a lifting seat 8 is provided on the outside of the machine base 1, a hydraulic lifting structure is provided inside the lifting seat 8, a connecting arm 9 is provided inside the lifting seat 8 and extends upward, and the end of the connecting arm 9 is connected to the pressure seat 10, as shown in FIG. Figure 1 and Figure 2 shown.

[0044] Among them, several groups of height measuring wheels 30 acting on the upper end surface of the packaging box are symmetrically installed on both sides of the bottom of the pressure seat 10. The right end of the pressure seat 10 is connected to the sealing mechanism 11. The sealing mechanism 11 is provided with a transmission chamber 12. The transmission chamber 12 is sequentially installed at the upper position of the transmission chamber 12. The tape wheel 13 is installed on the tape wheel 13. The tape 14 on the tape roll is sequentially transmitted through the first transmission wheel 31 and the second transmission wheel 32. Figure 3-Figure 5 shown.

[0045] In this embodiment, a curved motion track 15 is provided on the side wall of the transmission chamber 12. The curved motion track 15 is made of rubber and has wear-resistant and anti-slip properties. The shape and path of the curved motion track 15 are designed according to actual conditions and needs. The upper end of the curved motion track 15 is connected to a mounting port 16, and the lower end of the curved motion track 15 is connected to a disassembly port 17. The area of ​​the mounting port 16 and the disassembly port 17 are both larger than the positioning round seat 21. A plurality of groups of fixed teeth 18 are provided on one side of the interior of the curved motion track 15, and a sliding groove 19 is provided on the other side of the interior of the curved motion track 15. Figure 3-Figure 6 shown.

[0046] Specifically, a tape stretcher 20 is installed on the curved motion track 15, and the tape stretcher 20 includes a positioning round seat 21, such as Figure 5-Figure 6 shown.

[0047] Among them, the positioning round seat 21 is limited and fitted on the curved motion track 15, and has a certain static friction force. The interior of the positioning round seat 21 extends horizontally outward and is rotated to be provided with a stretching roller 22. The tape on the tape roll is attached to the stretching roller 22. The stretching roller 22 is riveted to the interior of the positioning round seat 21 through the positioning bearing seat 23. A fine blade 24 is provided on the stretching roller 22 to act on the tape 14. The installation position of the fine blade 24 needs to ensure that when the stretching roller 22 stretches the tape 14 along the curved motion track 15, the two do not touch each other. Figure 6-Figure 8 shown.

[0048] Among them, a small servo motor 25 is installed on the end of the positioning round seat 21 away from the stretching roller 22. The small servo motor 25 is connected to the traveling gear 27 through the rotating shaft 26. A wheel groove 28 is opened on the side of the positioning round seat 21 for the traveling gear 27 to partially extend. The traveling gear 27 moves on several groups of fixed teeth 18. A roller 29 is installed on the side of the positioning round seat 21 away from the traveling gear 27. The roller 29 partially extends out of the positioning round seat 21 and acts in the sliding groove 19, playing a role of limiting guidance. Figure 7-10 shown.

[0049] Furthermore, the rear pressure wheel 33, the tape cutting knife seat 34 and the front pressure wheel 42 are sequentially arranged at the lower position inside the transmission chamber 12 from right to left (the three are linked by a connecting rod tension spring structure, and the details can be referred to the existing carton sealing machine movement, which will not be described in detail). The two sides of the front pressure wheel 42 are symmetrically hinged with wheel frames 41, and the two sets of wheel frames 41 are fixed on the movable seat 40. There is a certain distance between the front pressure wheel 42 and the back of the tape 14. Therefore, when the front pressure wheel 42 and the packaging box are in instantaneous contact, the instantaneous contact force is likely to cause the tape 14 to deviate or wrinkle, such as Figure 4 and Figure 11 shown.

[0050] Among them, the left end surface of the movable seat 40 is symmetrically mounted with a belt pressing plate 43 on both sides, the belt pressing plate 43 is glued with an airbag seat 44, and two groups of airbag columns 45 are symmetrically mounted on the airbag seat 44. The airbag seat 44 and the airbag columns 45 are internally connected and both have deformation restoration performance. A flexible gap 46 is formed between the two groups of airbag columns 45 for the edge movement of the tape 14. Figure 11 and Figure 12 shown.

[0051] Furthermore, curved receiving grooves 50 are symmetrically provided on both sides of the right end surface of the movable seat 40. The curved receiving grooves 50 are arranged according to the movement path of the movable seat 40. A corrugated telescopic airbag 51 is provided in each set of curved receiving grooves 50. The corrugated telescopic airbag 51 is a corrugated structure with telescopic reset performance. Part of the corrugated telescopic airbag 51 extends out of the curved receiving groove 50. Figure 11 and Figure 12 shown.

[0052] Among them, the side wall of the transmission chamber 12 is symmetrically provided with a riveted sheet 53, and an extrusion block 54 is installed on the riveted sheet 53 to act on the corrugated telescopic airbag 51. The end of the corrugated telescopic airbag 51 away from the extrusion block 54 is connected to the interior of the airbag seat 44 through a connecting pipe 52. Figure 12 shown.

[0053] Furthermore, an inner wheel cavity 60 is opened inside the front pressure wheel 42, and a small air pump 61 is installed at one end of the inner wheel cavity 60. The air outlet 62 of the small air pump 61 is connected to the outside of the wheel frame 41 for exhausting air outwards. The air inlet pipe 63 of the small air pump 61 extends to the inside of the partition 64. The partition 64 is riveted in the inner wheel cavity 60, and a sealed chamber is provided inside the partition 64, such as Figure 13-14 shown.

[0054] In this embodiment, a sealed bearing 65 is installed at one end of the partition 64 away from the air intake pipe 63, and an L-shaped suction pipe 66 is inserted into the sealed bearing 65. A position sensor is installed on the L-shaped suction pipe 66 for timely detecting the position of the L-shaped suction pipe 66 and adjusting it. A large gear 70 is sleeved on the horizontal section 67 of the L-shaped suction pipe 66, and a small gear 71 is meshed with one side of the large gear 70. The small gear 71 is sleeved on the output shaft of a small drive motor 72, and the small drive motor 72 is horizontally mounted on the partition 64. Figure 13-14 shown.

[0055] In this embodiment, a plurality of groups of air flow channels 73 are evenly installed on the cavity wall of the inner wheel cavity 60. A plurality of groups of tape adsorption holes 75 are evenly opened at the position corresponding to the wheel surface of each group of air flow channels 73 and corresponding to the wheel surface of the front pressure wheel 42. The tape adsorption holes 75 evenly adsorb the tape 14 so that it is aligned with the wheel surface. A curved sealing joint 74 is installed on the inner side of each group of air flow channels 73. A sealing gasket is provided on the curved sealing joint 74 to play the role of sliding seal. The curved sealing joint 74 is butted against the end of the L-shaped suction pipe 66. Figure 13-14 shown.

[0056] Furthermore, the left end of the machine base 1 is connected to a feed roller mechanism 6, and the left ends of the two groups of box clamping conveyors 2 are both equipped with guide plates 7 extending into the feed roller mechanism 6 to play a role in limiting and guiding. Figure 1 shown.

[0057] Furthermore, the internal and external designs of the front pressure wheel 42 are all tiny parts, which do not affect the normal use of the front pressure wheel 42.

[0058] When using this embodiment, first buckle the tape onto the tape wheel 13 so that it can rotate with the tape wheel 13, then extend the positioning round seat 21 of the tape stretcher 20 from the mounting opening 16 into the curved motion track 15, so that the running gear 27 and the fixed teeth 18 are engaged, and at the same time, the roller 29 is pressed into the sliding groove 19, so that the entire positioning round seat 21 is stuck on the curved motion track 15, then the head tape 14 on the tape roll is flattened and touched to the stretching roller 22 (be careful not to touch the fine blade 24), and then start The small servo motor 25 and the rotating shaft 26 drive the traveling gear 27 to move counterclockwise, thereby driving the entire positioning round seat 21 to move downward along the curved motion track 15 through the meshing action with the fixed teeth 18 (the roller 29 is guided by rolling in the sliding groove 19). The stretching roller 22 pulls the tape 14 on the tape roll and slowly guides it out. It passes through the first and second conduction wheels 31 and 32 in sequence, and is wound around a local position of the guide wheel, forming a conduction state, until it moves to the lower end of the curved motion track 15.

[0059] By manually rotating the stretching roller 22 so that it rotates around the positioning bearing seat 23, the fine blade 24 contacts the tape 14 during the circular motion, and the fine blade 24 is used to cut the tape 14. Then, the tape stretcher 20 is manually removed from the disassembly port 17, and the tape 14 is pulled through the two sets of flexible gaps 46 until the back of the tape 14 faces the front pressure wheel 42.

[0060] At this time, a position sensor is used to detect the position of the L-shaped suction pipe 66, and then the small drive motor 72 is started, the small gear 71 rotates, and the large gear 70 is caused to rotate by meshing deceleration, so that the horizontal section 67 of the L-shaped suction pipe 66 rotates around the sealing bearing 65, and the pipe mouth point of the L-shaped suction pipe 66 performs a circular motion and moves to a group of air flow channels 73 positions closest to the tape 14, so that the pipe mouth and the curved sealing joint 74 are sealed and fitted. At this time, the small suction pump 61 is started to generate suction that acts on the air intake pipe 63, the L-shaped suction pipe 66 and the air flow channel 73 positions in turn, and finally the tape 14 at the lower end of the transmission chamber 12 is adsorbed on the wheel surface of the front pressure wheel 42 by the suction force of several groups of tape adsorption holes 75 to ensure that the two are fully fitted.

[0061] During operation, the packaging box is introduced to the top of the machine base 1 through the feeding roller mechanism 6. By making the two sets of clamping conveyors 2 move toward each other, the clamping belt 3 is used to clamp and position the packaging box. Then the lifting seat 8 works, and the connecting arm 9 drives the pressure seat 10 and the sealing mechanism 11 to descend together, so that several sets of height measuring wheels 30 are pressed down to the upper end surface of the packaging box. At this time, the two sets of clamping belts 3 synchronously clamp the packaging box and move it straight to the right (under the guidance of the No. 1 guide wheel 4 and the No. 2 guide wheel 5). The packaging box first contacts the tape 14 attached to the front pressure wheel 42 (at the same time, the suction of the tape adsorption hole 75 is removed), generating an extrusion force to make the movable seat 40 It rotates around the end, causing the front pressure wheel 42 to make an arc movement, so that the front pressure wheel 42 presses the tape 14 to the upper end surface of the packaging box to achieve box sealing. When the front pressure wheel 42 moves, the tape 14 will be tightened. At the same time, the two groups of corrugated telescopic airbags 51 contact the extrusion blocks 54 respectively as the front pressure wheel 42 moves, compressing the corrugated telescopic airbags 51. The air inside the airbags is injected into the airbag seat 44 through the connecting tube 52, causing the two groups of airbag columns 45 on the airbag seat 44 to expand and thicken after taking in air, thereby narrowing the flexible gap 46, improving the limiting effect on the edge of the tape 14, avoiding tape deviation, and increasing its tension. Example 2

[0062] On the basis of the first embodiment, the first embodiment uses the first guide wheel 4 and the second guide wheel 5 to guide the linear sealing movement of the packaging box. Due to the large number of guide wheels, they are prone to wear and damage, which increases the friction with the bottom of the packaging box, resulting in frequent equipment shutdowns and complicated maintenance. In order to solve the above technical problems, we have the following design, such as Figure 15-17 shown.

[0063] Specifically, a horizontal slot 80 is provided in the middle of the upper end surface of the base 1, and two sets of non-resistance guide slide bars 81 are symmetrically installed in the horizontal slot 80. A follower slide 82 is provided above the two sets of non-resistance guide slide bars 81 and extends out of the horizontal slot 80. Figure 15 shown.

[0064] Among them, the bottom of the follower slide 82 is provided with a plurality of welding blocks 83, and the lower end of the welding block 83 is connected to a resistance-free sliding sleeve 84 which is sleeved on the resistance-free guide slide rod 81, thereby improving the performance of the sliding guide. Figure 16 shown.

[0065] Furthermore, an adjustment plate 90 is equidistantly mounted on the upper end surface of the follower slide 82. The upper end surface of the adjustment plate 90 is provided with a smooth portion 91. The arc chamfer position of the adjustment plate 90 is provided with an anti-slip pattern portion 92. The anti-slip pattern portion 92 is provided with anti-slip patterns to increase friction resistance. Both the smooth portion 91 and the anti-slip pattern portion 92 act on the bottom of the packaging box. Figure 15 and Figure 17 shown.

[0066] In this embodiment, both ends of the adjustment plate 90 are welded with a short shaft 93, and the short shaft 93 is fixed by a damping bearing seat 94 and the inner wall of the follower slide 82. The short shaft 93 of one group of adjustment plates 90 extends outward and is connected to a servo motor 95 through a coupling. One to two groups of sprockets 96 are sleeved on the short shaft 93 of each group of adjustment plates 90. The adjacent sprockets 96 are used to rotate the adjustment plate 90 at an angle designed according to actual conditions, such as Figure 17 shown.

[0067] When the present embodiment is in use, the packaging box is introduced into the follower slide 82 of the machine base 1 through the feed roller mechanism 6. At this time, several groups of adjustment plates 90 are in a horizontal state, and the smooth portion 91 contacts the bottom of the packaging box. In the process of being positioned by the two groups of clamping belts 3, the packaging box slides freely on the follower slide 82 to adjust its position. When the packaging box is pressed down and positioned by the height measuring wheel 30, the servo motor 95 is started to drive one group of adjustment plates 90 to rotate, and the sprocket 96 and the small chain 97 on the short shaft 93 are connected and driven in sequence, so that several groups of adjustment plates 90 rotate synchronously in the same direction, so that the anti-slip groove 92 of each group of adjustment plates 90 contacts the bottom of the packaging box and slightly lifts the cardboard (the entire cardboard of the packaging box undergoes micro-deformation) to enhance the contact force. At this time, the two groups of clamping belts 3 synchronously clamp the packaging box and move straight to the right to seal the box. The follower slide 82 slides with low resistance on the two groups of resistance-free guide slides 81 and moves straight to the right with the packaging box.
