Description

Technical Field

[0001] The present invention relates to the technical field of carton sealing, and particularly relates to a carton sealer for automatically installing tape. Background Art

[0002] A carton sealer is a commonly used packaging machine, mainly used for sealing cartons or paper boxes. It is suitable for single-machine operation or forming an automated packaging production line with an unpacking machine, a packing machine, etc. It uses BOPP instant adhesive tape (sealing tape) to seal cartons, and can seal both the upper and lower sides of the carton simultaneously, with the characteristics of fast packaging speed, high efficiency, and good appearance. When in use, the carton sealer first clamps the packaging box with a belt, then measures the height of the packaging box with a height measuring wheel, adjusts the height position of the carton sealing core, and finally seals the tape on the packaging box with the carton sealing core.

[0003] Existing carton sealers have many technical defects when in use. Firstly, for the tape roll on the first core, manual threading of the tape is required during the first use to enable the tape to be supplied around multiple groups of guide rollers. However, manual threading is time-consuming and laborious, with a large amount of tape waste, and it is easy to cut the hand with the bottom cutter. Secondly, the pressure tape piece on the second core is used to guide and correct the deviation of the tape on the front pressure wheel. However, since the commonly used pressure tape piece is made of metal, when the tape is tightened for sealing, the edge of the tape is affected by the pressure tape piece and is prone to deformation and bending, reducing the guiding and deviation-correcting effects and resulting in tape wrinkles at the sealing position. Thirdly, the current carton sealer uses guide wheels to guide the linear sealing movement of the packaging box. Due to the large number of guide wheels, wear and damage are likely to occur (generally heavy objects are placed in the packaging box), increasing the friction with the bottom of the packaging box and causing the equipment to stop frequently.

[0004] In summary, considering that the existing facilities cannot meet the working requirements, for this reason, we propose a carton sealer for automatically installing tape. Summary of the Invention

Short shafts are welded at both ends of the adjusting plate, and the short shafts are fixed to the inner wall of the follower sliding seat through damping bearing seats. The short shaft of one of the adjusting plates extends outwards and is connected with a servo motor through a coupling. One or two groups of sprockets are sleeved on each short shaft of the adjusting plates, and adjacent sprockets are connected and driven by a small chain.

[0017] The present invention provides a carton sealing machine for automatically installing tape through improvement. Compared with the prior art, it has the following remarkable improvements and advantages: Start the small servo motor, the rotating shaft drives the walking gear to move counterclockwise, drives the entire positioning circular seat to move downward along the curved movement track, the stretching roller slowly pulls out the tape on the tape roll, passes through the first conduction wheel and the second conduction wheel in sequence, winds the tape around a partial position of the guide wheel to form a conduction state, until it moves to the lower end of the curved movement track, achieving the purpose of automatically threading the tape, saving time and effort.

[0019] With the power of the movable seat, the two groups of corrugated telescopic airbags contact the extrusion blocks respectively as the front pressing wheel moves, compressing the corrugated telescopic airbags. The air inside them is injected into the airbag seat through the connecting pipe, causing the two groups of airbag columns on the airbag seat to expand and thicken after intake, thereby narrowing the flexible gap, improving the limiting effect on the tape edge, avoiding tape deviation, and increasing its tension. It takes into account the flexibility and limiting property of the tape pressing piece, significantly improving the tape pressing effect and replacing the tape pressing piece made of metal material.

Make the anti-slip pattern parts of each group of adjusting plates contact the bottom of the packing box and slightly lift the cardboard to enhance the contact force. The two groups of clamping belts clamp the packing box and move straight to the right for sealing. The follower sliding seat slides and guides with low resistance on the two groups of non-resistance guiding sliding rods, moving straight to the right together with the packing box, increasing the sliding guiding performance of the bottom of the packing box and solving the problem of equipment shutdown caused by the wear of the guiding wheels.

Specific embodiments

[0023] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention. Embodiment 1

[0024] As Figures 1-14As shown in the figure, this embodiment provides a carton sealer for automatically installing tape, which includes a machine base 1. On both sides of the upper end surface of the machine base 1, clamping conveyors 2 are symmetrically and movably arranged. The clamping conveyors 2 are driven by a cylinder structure. Inside the clamping conveyors 2, there are clamping belts 3 acting on the packaging boxes. At equal intervals in the middle position of the upper end surface of the machine base 1, several groups of first guide wheels 4 are arranged. On the upper end surface of the machine base 1 and symmetrically on the inner side of the clamping conveyors 2, several groups of second guide wheels 5 are arranged. The number and position of the guide wheels are set according to the actual situation.

[0025] Furthermore, a lifting seat 8 is arranged on the outside of the machine base 1. Inside the lifting seat 8, a hydraulic lifting structure is arranged. Inside the lifting seat 8, a connecting arm 9 extends upward and movably. The end of the connecting arm 9 is connected to a pressure seat 10, as Figure 1 and Figure 2 shown.

[0026] Among them, on both sides of the bottom of the pressure seat 10, several groups of height measuring wheels 30 acting on the upper end surface of the packaging box are symmetrically installed. The right end of the pressure seat 10 is connected to a carton sealing core 11. Inside the carton sealing core 11, there is a transmission chamber 12. Inside the transmission chamber 12, a tape wheel 13, a first conduction wheel 31 and a second conduction wheel 32 (not limited to two groups of conduction wheels) are successively installed at the upper position. A tape roll is installed on the tape wheel 13. The tape 14 on the tape roll is successively conducted through the first conduction wheel 31 and the second conduction wheel 32, as Figures 3-5 shown.

[0027] In this embodiment, a curved motion track 15 is opened on the side wall of the transmission chamber 12. The curved motion track 15 is made of rubber material and has the functions of wear resistance and anti-slip. The shape path of the curved motion track 15 is designed according to the actual situation and needs. The upper end of the curved motion track 15 is connected to an installation port 16, and the lower end of the curved motion track 15 is connected to a disassembly port 17. The areas of the installation port 16 and the disassembly port 17 are both larger than the positioning circular seat 21. On one side inside the curved motion track 15, several groups of fixed teeth 18 are arranged. On the other side inside the curved motion track 15, a sliding groove 19 is opened, as Figures 3-6 shown.

[0028] Specifically, a tape stretcher 20 is installed on the curved motion track 15. The tape stretcher 20 includes a positioning circular seat 21, as Figures 5-6 shown.

[0029] Among them, the positioning circular seat 21 is limited and fitted on the curved motion track 15 with a certain static friction force. A stretching roller 22 is horizontally extended and rotatably arranged inside the positioning circular seat 21. The tape on the tape roll is pasted on the stretching roller 22. The stretching roller 22 is riveted to the inside of the positioning circular seat 21 through a positioning bearing seat 23. A thin blade 24 acting on the tape 14 is arranged on the stretching roller 22. The installation position of the thin 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 come into contact. Figures 6-8 as shown.

[0030] Among them, a small servo motor 25 is installed through one end of the positioning circular seat 21 far away from the stretching roller 22. A walking gear 27 is sleeved on the rotating shaft 26 of the small servo motor 25. A wheel groove 28 for partial protrusion of the walking gear 27 is formed on the side of the positioning circular seat 21. The walking gear 27 moves on a number of fixed teeth 18. A roller 29 is installed on one side of the positioning circular seat 21 far away from the walking gear 27. A part of the roller 29 protrudes outside the positioning circular seat 21 and acts in the sliding groove 19 to play a role in limiting and guiding, as Figures 7-10 shown.

[0031] Further, a rear pressure wheel 33, a tape cutting knife seat 34 and a front pressure wheel 42 are sequentially arranged from right to left at a lower position inside the transmission chamber 12 (the three are linked through a connecting rod and spring structure. For details, reference can be made to the existing sealing machine movement and will not be elaborated here). Wheel frames 41 are symmetrically hinged on both sides of the front pressure wheel 42. The two groups of wheel frames 41 are fixed on the movable seat 40. There is a certain distance gap between the front pressure wheel 42 and the back of the tape 14. Therefore, when the front pressure wheel 42 comes into contact with the packaging box instantaneously, the instantaneous contact force is likely to cause the tape 14 to deviate or wrinkle, as Figure 4 and Figure 11 shown.

[0032] Among them, pressing plates 43 are symmetrically installed on both sides of the left end face of the movable seat 40. Airbag seats 44 are adhesively bonded to the pressing plates 43. Two groups of airbag columns 45 are symmetrically installed on the airbag seats 44. The inside of the airbag seats 44 and the airbag columns 45 is communicated and both have deformation and reset performance. A flexible gap 46 for the edge movement of the tape 14 is formed between the two groups of airbag columns 45, as Figure 11 and Figure 12 shown.

[0033] Further, curved storage grooves 50 are symmetrically formed on both sides of the right end face of the movable seat 40. The curved storage grooves 50 are arranged according to the movement path of the movable seat 40. A corrugated telescopic airbag 51 is arranged in each curved storage groove 50. The corrugated telescopic airbag 51 is of a corrugated structure and has telescopic and reset performance. A part of the corrugated telescopic airbag 51 protrudes outside the curved storage groove 50, as Figure 11 and Figure 12 shown.

[0034] Among them, riveting pieces 53 are symmetrically arranged on the side wall of the transmission chamber 12. An extrusion block 54 acting on the corrugated expansion airbag 51 is installed on the riveting piece 53. One end of the corrugated expansion airbag 51 far from the extrusion block 54 is connected to the inside of the airbag seat 44 through a connecting pipe 52, as Figure 12 shown.

[0035] Furthermore, an inner wheel cavity 60 is formed inside the front pressure wheel 42. A small air suction pump 61 is installed at one end of the inner wheel cavity 60. The air outlet hole 62 of the small air suction pump 61 is connected to the outside of the wheel frame 41 for exhausting air outward. The air inlet pipe 63 of the small air suction pump 61 extends into the inside of the partition plate 64. The partition plate 64 is riveted in the inner wheel cavity 60. A sealed chamber is arranged inside the partition plate 64, as Figures 13-14 shown.

[0036] In this embodiment, a sealed bearing 65 is installed at one end of the partition plate 64 far from the air inlet pipe 63. 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 to timely detect the position of the L-shaped suction pipe 66 and adjust it. A large gear 70 is sleeved on the horizontal section 67 of the L-shaped suction pipe 66. A small gear 71 is meshed on one side of the large gear 70. The small gear 71 is sleeved on the output shaft of a small driving motor 72. The small driving motor 72 is horizontally installed on the partition plate 64, as Figures 13-14 shown.

[0037] In this embodiment, a number of groups of air flow channels 73 are evenly installed on the wall of the inner wheel cavity 60. A number of groups of tape adsorption holes 75 are evenly formed at positions corresponding to the wheel surface of the front pressure wheel 42 for each group of air flow channels 73. The tape adsorption holes 75 evenly adsorb the tape 14 to align it with the wheel surface. A curved sealing joint 74 is installed inside each group of air flow channels 73. A sealing gasket is arranged on the curved sealing joint 74 to play a role of sliding seal. The curved sealing joint 74 is butted against the end of the L-shaped suction pipe 66, as Figures 13-14 shown.

[0038] Furthermore, a feeding roller mechanism 6 is connected to the left end of the machine base 1. Guide plates 7 extending into the feeding roller mechanism 6 are installed at the left ends of the two clamping box conveyors 2 to play a role of limiting and guiding, as Figure 1 shown.

[0039] Furthermore, the internal and external designs of the front pressure wheel 42 are all composed of tiny parts, which do not affect the normal use of the front pressure wheel 42.

[0040] When this embodiment is in use, first, the tape roll is buckled onto the tape wheel 13 and can rotate with the tape wheel 13. Then, the positioning round seat 21 of the tape stretcher 20 is inserted into the curved motion track 15 from the installation opening 16, so that the walking gear 27 meshes with the fixed teeth 18. At the same time, the roller 29 abuts against the sliding groove 19, so that the entire positioning round seat 21 is stuck on the curved motion track 15. At this time, the head tape 14 on the tape roll is flattened and adhered to the stretching roller 22 (note not to touch the fine blade 24). Then, the small servo motor 25 is started, and the rotating shaft 26 drives the walking gear 27 to rotate counterclockwise. Thus, through the meshing action with the fixed teeth 18, the entire positioning round seat 21 is driven to move downward along the curved motion track 15 (the roller 29 rolls and guides in the sliding groove 19), and the stretching roller 22 pulls the tape 14 on the tape roll out slowly, passing through the first conduction wheel 31 and the second conduction wheel 32 in sequence, and winding the tape 14 around a partial position of the guide wheel to form a conduction state until it moves to the lower end of the curved motion track 15.

[0041] By manually rotating the stretching roller 22 to make it rotate around the positioning bearing seat 23, the fine blade 24 contacts the tape 14 during the circular motion process, and the tape 14 is cut by the fine blade 24. Then, the tape stretcher 20 is manually taken out from the disassembly opening 17, and the tape 14 is pulled through the two groups of flexible gaps 46 until the back surface of the tape 14 faces the position of the front pressure wheel 42.

[0042] At this time, the position sensor is used to detect the orientation of the L-shaped suction pipe 66. Then, the small driving motor 72 is started, the small gear 71 rotates, and the large gear 70 is driven to rotate through meshing and deceleration, so that the horizontal section 67 of the L-shaped suction pipe 66 rotates around the sealing bearing 65. The pipe orifice point of the L-shaped suction pipe 66 makes a circular motion and moves to the position of a group of air flow channels 73 closest to the tape 14, and the pipe orifice is hermetically fitted with the curved sealing joint 74. At this time, the small suction pump 61 is started, and the suction force acts on the intake pipe 63, the L-shaped suction pipe 66, and the air flow channel 73 in sequence. 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 full adhesion between the two.

[0043] During operation, the packing box is introduced above the machine base 1 through the feeding roller mechanism 6. By moving two sets of box clamping conveyors 2 towards each other, the packing box is clamped and positioned using the clamping belts 3. Then, the lifting seat 8 operates, and the connecting arm 9 drives the pressure seat 10 and the box sealing core 11 to descend together, causing several sets of height measuring wheels 30 to press down on the upper end surface of the packing box. At this time, the two sets of clamping belts 3 clamp the packing box and move linearly to the right synchronously (under the guiding action of the first guiding wheel 4 and the second guiding wheel 5). The packing box first contacts the tape 14 attached to the front pressing wheel 42 (while the suction force of the tape suction hole 75 is removed), generating a squeezing force that causes the movable seat 40 to rotate around the end, thereby making the front pressing wheel 42 move in an arc, and the front pressing wheel 42 presses the tape 14 onto the upper end surface of the packing box to complete box sealing. When the front pressing wheel 42 moves, the tape 14 will be tightened. At the same time, the two corrugated telescopic air bags 51 contact the extrusion blocks 54 respectively as the front pressing wheel 42 moves, compressing the corrugated telescopic air bags 51. The air inside them is injected into the air bag seat 44 through the connecting pipe 52, causing the two air bag columns 45 on the air bag seat 44 to inflate and thicken respectively after intake, thereby narrowing the flexible gap 46, improving the limiting effect on the edge of the tape 14, preventing tape deviation, and increasing its tension. Embodiment 2

[0044] On the basis of Embodiment 1, in Embodiment 1, the first guiding wheel 4 and the second guiding wheel 5 are used to guide the linear box sealing movement of the packing box. Due to the large number of guiding wheels, wear and damage are likely to occur, increasing the friction force with the bottom of the packing box, resulting in frequent equipment shutdowns and cumbersome maintenance. To solve the above technical problems, we have the following design, as Figures 15-17 shown.

[0045] Specifically, a horizontal groove 80 is provided at the middle position of the upper end surface of the machine base 1. Two sets of resistance-free guiding slide rods 81 are symmetrically installed in the horizontal groove 80. Above the two sets of resistance-free guiding slide rods 81, a follower slide seat 82 is provided outside the horizontal groove 80, as Figure 15 shown.

[0046] Among them, several welding blocks 83 are provided at the bottom of the follower slide seat 82. The lower ends of the welding blocks 83 are connected with resistance-free sliding sleeves 84 sleeved on the resistance-free guiding slide rods 81, thereby improving the sliding guiding performance, as Figure 16 shown.

[0047] Furthermore, adjusting plates 90 are equidistantly installed on the upper end surface of the follower slide seat 82. A smooth part 91 is provided on the upper end surface of the adjusting plate 90, and an anti-slip texture part 92 is provided at the arc chamfer position of the adjusting plate 90. Anti-slip textures are provided on the anti-slip texture part 92 to increase the frictional resistance. Both the smooth part 91 and the anti-slip texture part 92 act on the bottom of the packing box, as Figure 15 and Figure 17 shown.

[0048] In this embodiment, short shafts 93 are welded to both ends of the adjusting plate 90. The short shafts 93 are fixed to the inner wall of the follower slide 82 through damping bearing seats 94. The short shaft 93 of one set of adjusting plates 90 extends outward and is connected to a servo motor 95 through a coupling. One or two sets of sprockets 96 are sleeved on the short shaft 93 of each set of adjusting plates 90. The angle of rotation of the adjusting plate 90 is designed according to the actual situation, such as Figure 17 shown.

[0049] When this embodiment is in use, the packaging box is introduced onto the follower slide 82 of the machine base 1 through the feeding roller mechanism 6. At this time, several sets of adjusting plates 90 are in a horizontal state, and the smooth portion 91 contacts the bottom of the packaging box. During the process of the packaging box being positioned by the two sets of clamping belts 3, it can slide freely on the follower slide 82 to adjust its position. When the packaging box is pressed and positioned by the height measuring wheel 30, the servo motor 95 is started at this time, driving one set of adjusting plates 90 to rotate, and sequentially connecting and driving through the sprockets 96 and the small chain 97 on the short shaft 93, so that several sets of adjusting plates 90 rotate synchronously in the same direction, making the anti-slip pattern portion 92 of each set of adjusting plates 90 contact the bottom of the packaging box and slightly lift the cardboard (the overall cardboard of the packaging box undergoes a slight deformation), enhancing the contact force. At this time, the two sets of clamping belts 3 clamp the packaging box and move straight to the right for sealing. The follower slide 82 slides and is guided with low resistance on the two sets of non-resistance guiding slide rods 81 and moves straight to the right together with the packaging box.
