Description

Technical Field

[0001] This application relates to the technical field of packaging equipment, and in particular to a device for applying adhesive tape to inner bags of containers. Background Technology

[0002] Container inner bags, as large flexible packaging containers, are widely used in the logistics and transportation field, mainly for loading bulk goods such as liquids, powders, and granules. After the materials are filled, sealing tape is usually used to seal the opening to secure and seal the inner bag.

[0003] Currently, in pursuit of ease and efficiency, adhesive tape with individual release liner is commonly used to seal and secure the openings of the inner bags of containers. However, in actual use, this release liner, which serves as a barrier, is discarded after being torn off, generating solid waste. This single-use consumption not only directly increases the material cost per use, but the disposal of its waste may also indirectly drive up the overall operating and management costs, leading to an increase in overall production costs.

[0004] Regarding the aforementioned prior art, the inventor believes that its main drawback is that the use of tape with release paper results in unnecessary material waste, thereby increasing production costs. Summary of the Invention

[0005] In order to improve the problems of material waste and high production costs caused by the use of tape with release paper in the prior art, this application provides a device for applying tape to the inner bag of a container.

The folding module is connected to the base via a linkage structure.

[0007] By adopting the above technical solution and integrating functions such as roll forming, conveying, dispensing, cutting and folding, a fully automated operation from substrate supply to tape forming is achieved. This not only improves the efficiency of tape application, but also reduces material waste and solid waste by eliminating the release paper.

[0008] Preferably, the base is provided with a guide groove, and the linkage structure is disposed in the guide groove; The base is also provided with a support frame, which includes a vertical part and a horizontal part, and the dispensing structure is provided on the horizontal part; A mounting base is fixedly provided on the base, and both the transmission device and the cutting device are mounted on the mounting base.

[0009] By adopting the above technical solution, the guide groove provides a precise guiding path for the linkage structure, and the support frame and mounting base ensure the stable installation of the dispensing structure, transmission device and cutting device, thereby improving the overall rigidity and operational accuracy.

[0010] Preferably, the linkage structure includes a first linear actuator disposed in the guide groove.

The ends of the two conveying rollers are respectively fixedly connected to the corresponding transmission gear one or transmission gear two. The second support frame is also provided with a protective cover for accommodating the transmission gears.

[0015] By adopting the above technical solution, the drive mechanism achieves synchronous opposite rotation of the two rollers through gear transmission, ensuring the synchronicity and stability of substrate conveying.

A second linear driver is also connected between the two connecting ears on the same side.

[0017] By adopting the above technical solution, the second linear driver drives the upper mold base to press down along the guide column, so that the cutting blade and the cutting groove cooperate to complete the clean cutting. The reset elastic element assists in rapid reset. The specially designed bottom surface of the mold base presses down on the cut substrate during cutting to prevent displacement and ensure cutting accuracy and continuity.

[0023] Preferably, the mounting plate is further provided with a leveling component and a first sensing element, and one of the clamping plates is provided with a second sensing element.

[0039] The following is in conjunction with the appendix Figure 1 - Appendix Figure 11 This application will be described in further detail.

[0040] Example 1: The container inner bag tape applicator disclosed in this application is described in reference to... Figure 1 and Figure 4 As shown, the system includes a base 1, wherein a guide groove 11 is formed in the middle of the front side of the top end of the base 1, and a linkage structure 7 is provided in the guide groove 11. At the same time, a folding module 6 is connected to the front side of the top end of the base 1. Through the operation of the linkage structure 7, the folding module 6 is driven to move back and forth at the top end of the base 1.

[0041] Specifically, refer to Figure 2As shown, the linkage structure 7 includes a first linear actuator 71 disposed within the guide groove 11. A first connecting seat 72 is fixedly connected to the outer wall of the first linear actuator 71, and the first connecting seat 72 is fixedly connected to the bottom wall of the guide groove 11. Simultaneously, a second connecting seat 73 is fixedly connected to the output end of the first linear actuator 71, and the bottom end of the second connecting seat 73 is slidably connected to the bottom wall of the guide groove 11.

[0042] Reference Figure 3 and Figure 4 As shown, the folding module 6 includes a pair of clamping plates 61 connected by a hinge 62 (a hinge is used in this embodiment), arranged symmetrically front to back. The two clamping plates 61 can rotate around the hinge point, stacking when closed and unfolding into a 180° planar state. The two clamping plates 61 abut against each other after unfolding to prevent excessive rotation. A sliding seat 63 is fixedly connected to the bottom end of the front clamping plate 61. The bottom end of the sliding seat 63 is fixedly connected to the top end of the second connecting seat 73, and the bottom end of the sliding seat 63 is slidably connected to the top end of the base 1 to ensure the stability of the overall movement.

[0043] Operating principle: When the first linear actuator 71 extends or retracts, it can drive the entire folding module 6 to move back and forth at the top of the base 1 through the second connecting seat 73.

[0044] Reference Figure 5 As shown, a winding device 2 is provided at the rear of the top of the base 1 to provide a continuous strip of substrate for subsequent processes. This winding device 2 mainly consists of a pair of first support frames 21 and several winding rollers 22. The pair of first support frames 21 are fixedly connected to the base 1 and arranged symmetrically on both sides. The several winding rollers 22 are rotatably connected to the opposite inner sides of the two first support frames 21 in an up-down arrangement.

[0045] Reference Figure 1 and Figure 6 As shown, a mounting base 9 is fixedly connected to the middle of the top of the base 1, and a transmission device 3 and a cutting device 5 are connected sequentially from back to front to the top of the mounting base 9.

[0046] Specifically, refer to Figure 6 As shown, the conveying device 3 includes a pair of second support frames 31, a pair of conveying rollers 32, and a drive mechanism 33 for driving the pair of conveying rollers 32 to rotate. The pair of second support frames 31 are fixedly connected to the mounting base 9 and are arranged symmetrically on both sides. The pair of conveying rollers 32 are rotatably connected to the adjacent sides of the two second support frames 31.

[0047] The drive mechanism 33 includes a drive source 331. In this embodiment, the drive source 331 is a geared motor, which is fixedly connected to the outer wall of one of the second support frames 31 via a motor mount. The output shaft of the drive source 331 passes through the second support frame 31 and is fixedly connected to the corresponding conveying roller 32. Meanwhile, a pair of meshing transmission gears, a first transmission gear 332 and a second transmission gear 333, are connected to the other second support frame 31 (the side furthest from the drive source 331). It should be noted that the first transmission gear 332 and the second transmission gear 333 have the same diameter. Both conveying rollers 32 pass through the second support frame 31 and are fixedly connected to the corresponding first transmission gear 332 or second transmission gear 333. Finally, a protective cover 334 is fixedly connected to the second support frame 31 to enclose the first transmission gear 332 or the second transmission gear 333.

[0048] Operating principle: When the drive source 331 runs, it drives the corresponding conveyor roller 32 to rotate and connect. At the same time, through the meshing of the first transmission gear 332 and the second transmission gear 333, it drives the other conveyor roller 32 to rotate in the other direction. That is, the two conveyor rollers 32 rotate simultaneously towards the side close to each other or the side far apart.

[0049] Reference Figure 7 and Figure 8 As shown, the cutting device 5 includes a lower mold base 51 and an upper mold base 52, as well as at least two second linear actuators 56 (an even number of second linear actuators 56) that push the upper mold base 52 to move up and down.

[0050] The lower mold base 51 is fixedly connected to the mounting base 9, and the upper mold base 52 is located above the lower mold base 51. Connecting ears 53 are fixedly connected to both sides of the lower mold base 51 and the upper mold base 52. Several second linear actuators 56 are divided into two groups, arranged symmetrically, with the bottom end of each second linear actuator 56 fixedly connected to the connecting ear 53 of the lower mold base 51, and the output rod of each second linear actuator 56 fixedly connected to the connecting ear 53 of the upper mold base 52.

[0051] A cutting groove 511 is provided at the front of the top of the lower mold base 51, and a cutting blade 521 is fixedly connected to the bottom of the upper mold base 52. When the lower mold base 51 and the upper mold base 52 come into contact, the cutting blade 521 is engaged in the cutting groove 511.

[0052] Each upper mold base 52 has a guide post 54 passing through its connecting lug 53, and the bottom end of the guide post 54 is fixedly connected to the connecting lug 53 of the lower mold base 51. A reset elastic element 55 is sleeved on the guide post 54. In this embodiment, a reset spring is selected, wherein the top and bottom ends of the reset elastic element 55 are fixedly connected to the two connecting lugs 53 on the same side, respectively.

[0053] Operating principle: The strip substrate is precisely conveyed to a designated position on the upper surface of the lower die holder 51. Subsequently, the second linear actuator 56 receives a signal and begins to retract, pulling the upper die holder 52 downward along the trajectory defined by the guide post 54. The reset elastic element 55 is compressed during this process. The cutting blade 521 then contacts and presses against the substrate, ultimately working in conjunction with the cutting groove 511 to cleanly and efficiently cut the substrate.

[0054] A key design feature is the special structure of the bottom surface of the upper mold base 52: the area located behind the cutting blade 521 will be in close contact with the upper surface of the lower mold base 51 or have a very small gap when the mold is closed, thereby pressing down the cut substrate segment and preventing it from moving during the cutting action; while the area located in front of the cutting blade 521 is designed to maintain a certain gap when the mold is closed with the lower mold base 51 to avoid pressing down the new substrate that has not yet been cut, thereby ensuring that the substrate can be continuously transported to the cutting station and ensuring the continuity of production.

[0055] Reference Figure 9 and Figure 10 As shown, a support frame 8 is also provided on the base 1. The support frame 8 includes a vertical part 81 and a horizontal part 82. The vertical part 81 is fixedly connected to the base 1, and the horizontal part 82 is fixedly connected to the top of the vertical part 81. A dotted adhesive structure 4 is provided at the bottom of the horizontal part 82 for applying adhesive to the cut substrate segment.

[0056] Specifically, the dispensing structure 4 includes a porous dispensing head 41, at least two guide members 44 (limiting telescopic rods), and a third linear actuator 43. The two guide members 44 and the third linear actuator 43 are all fixedly connected to the bottom end of the transverse portion 82, and the two guide members 44 are symmetrically arranged on both sides of the third linear actuator 43. The output ends of the two guide members 44 and the third linear actuator 43 are jointly fixedly connected to a mounting plate 42. The dispensing head 41 is fixedly connected to the bottom end of the mounting plate 42.

[0057] The dispensing structure 4 also includes an adhesive supply system 45 for delivering adhesive to the dispensing head 41. Meanwhile, a leveling component 421, which is a scraper, is fixedly connected to the bottom of the mounting plate 42 near the transmission device 3.

[0058] The dispensing structure 4 includes a delivery pump 451, a first pipeline 452, and a second pipeline 453. The delivery pump 451 is fixedly connected to the inner wall of the vertical portion 81. The first pipeline 452 is fixedly connected to the outlet of the delivery pump 451, and its other end is connected to the dispensing head 41. The second pipeline 453 is connected to the inlet of the delivery pump 451, and its other end is connected to an external glue supply source.

[0059] Operating principle: When the glue supply system 45 is activated, the delivery pump 451 draws glue from an external glue source through the second pipeline 453, and then delivers it to the dispensing head 41 through the first pipeline 452. Driven by the third linear actuator 43, the dispensing head 41 descends to a preset height, precisely applying the glue to the substrate surface. The leveling component 421 (scraper) on the mounting plate 42 then smooths the glue layer or substrate surface to ensure uniform glue application.

[0060] Example 2: Because the substrate may shift unnecessarily during the application and smoothing of the adhesive, which can affect the accuracy of subsequent adhesive application, Example 2 is proposed to reduce the occurrence of such situations.

[0061] Reference Figure 3 and Figure 4 As shown, both clamping plates 61 have cavities 611 inside, and their surfaces have several adsorption holes 612 that communicate with the cavities 611. Filter elements 613 (filter blocks) are fixedly connected to the inner walls of the adsorption holes 612.

[0062] Meanwhile, the sliding seat 63 is fixedly connected with the same number of negative pressure generating devices 631 as the clamping plates 61. The negative pressure generating device 631 (selected as an air pump) is fixedly connected to the air outlet of the negative pressure generating device 631 with a fluid pipeline 632 fixedly connected to it. The other end is connected to the clamping plate 61 and communicates with the cavity 611 of the corresponding clamping plate 61.

[0063] It should be noted that the surfaces of the two clamping plates 61 have no protrusions.

[0064] Operating principle: When the substrate is attached to the surface of the clamping plate 61 and the adsorption hole 612 is blocked, the negative pressure generating device 631 operates to generate a negative pressure effect, allowing atmospheric pressure to press the substrate onto the surface of the clamping plate 61.

[0065] Example 3: Reference Figure 1 As shown, a controller (PLC) is fixedly connected to the base 1.

[0066] Reference Figure 4 and Figure 10 As shown, a second sensing element 614 is provided on the surface of the clamping plate 61 connected to the sliding seat 63. A first sensing element 422 is fixedly connected to the side of the mounting plate 42 away from the leveling member 421. It should be noted that the first sensing element 422 is an infrared transmitter, and the second sensing element 614 is an infrared receiver. The first sensing element 422 and the second sensing element 614 are connected by optical signals.

[0067] The controller is electrically connected to the first sensing element 422 and the second sensing element 614, the drive source 331, the second linear driver 56, the third linear driver 43, the delivery pump 451, the first linear driver 71, and the negative pressure generating device 631.

[0068] Among them, the first linear actuator 71, the second linear actuator 56, and the third linear actuator 43 are all electric telescopic rods.

[0069] The implementation principle of the container inner bag tape applicator in this application embodiment is as follows: The substrate is wound onto the roll roller 22, and the other end passes between two conveyor rollers 32 before being guided to the cutting station between the lower die holder 51 and the upper die holder 52. After the material is threaded, the equipment is started, and the drive source 331 starts working. Through the meshing of the transmission gear 1 332 and the transmission gear 2 333, the pair of conveyor rollers 32 are driven to rotate in opposite directions, thereby pulling the substrate forward in a step-by-step conveying motion.

[0070] When the substrate blocks the light signal emitted by the first sensing element 422 to the second sensing element 614, the controller determines that the substrate is in position and immediately pauses the drive source 331. Then, the second linear actuator 56 drives the upper mold base 52 to move downward along the guide post 54, and the cutting blade 521 fixed at its bottom engages with the cutting groove 511 on the lower mold base 51 to cut the substrate. After cutting, the second linear actuator 56 resets, and the upper mold base 52 returns to its original position with the assistance of the reset elastic element 55.

[0071] The negative pressure generating device 631 is activated, creating negative pressure within the cavity 611 of the clamping plate 61, which adsorbs and fixes the substrate segment to the surface of the clamping plate 61. The third linear actuator 43 actuates, pushing the mounting plate 42 and the dispensing head 41 down to a preset height. Simultaneously, the delivery pump 451 starts, pumping adhesive from an external adhesive source into the dispensing head 41 through the second pipeline 453 and the first pipeline 452, allowing for precise application onto the substrate surface. Next, the first linear actuator 71 of the linkage structure 7 operates, moving the entire folding module 6 forward. At this point, adhesive can be applied to other areas of the substrate. When the middle area of ​​the substrate is about to reach below the dispensing head 41, the controller stops the delivery pump 451. When the substrate moves to the next area, i.e., the non-middle area, the delivery pump 451 starts running again, continuing the adhesive application to the substrate surface. At the same time, the leveling component 421 on the mounting plate 42 smooths the adhesive layer, ensuring uniform adhesive application. After adhesive application is complete, the dispensing head 41 is raised, and the substrate continues to move forward.

[0072] When the folding module 6 moves away from the dispensing structure 4 area and reaches a position with sufficient space for the clamping plate 61 to rotate, the first linear actuator 71 stops operating. The inner bag of the container is then placed between the pair of clamping plates 61. The clamping plate 61 at its movable end then rotates relative to the hinge 62, folding the substrate section in half and adhering its adhesive surface. Finally, the formed tape is applied to the opening of the inner bag of the container, completing the sealing operation. After application, the negative pressure is released, restoring the movable clamping plate 61 to its original position. The first linear actuator 71 then drives the folding module 6 back to its initial position, and the equipment enters the next work cycle.

[0073] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
