[0002] In the sewing product packaging industry, the traditional glue bag tear glue sealing mechanism has some limitations. For example, the efficiency of the way of using a mechanical hand to position and tear glue is low, and it takes a long time. In the patent with the application number of 201910383832.9 and the name of glue bag tear glue sealing mechanism, when tearing glue, the glue bag is first positioned by a positioning assembly, then the glue strip is blown up by using a blowing pipe, and the blown-up glue strip is clamped by a clamping jaw under the drive of a clamping power element, and finally the glue strip is completely torn off under the cooperation of a moving assembly. Although this way can make the clamping jaw clamp the glue strip at a certain probability, the glue strip will continue to vibrate under the action of the blowing flow when blowing, which can easily cause the clamping jaw to fail when clamping the glue strip.

It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0026] The plastic bag tearing and sealing device provided by this utility model is mainly used in packaging equipment to tear off the adhesive strip 101 on the adhesive part of the plastic bag 100 and seal the plastic bag.

An adhesive strip 101 is provided on the adhesive part to prevent the backing adhesive from curing, and the width of the adhesive strip 101 is greater than the adhesive part. This invention uses a clamping and translational component to control the clamping component to move forward horizontally, simulating the effect of manually tearing adhesive horizontally.

[0027] Please see Figure 2 The adhesive bag tearing and sealing device 5 provided by this utility model includes a clamping assembly 51 for clamping the adhesive strip 100, a clamping lifting assembly 52 for controlling the lifting and lowering of the clamping assembly 51, a clamping translation assembly 53 for tearing off the adhesive strip, and a sealing assembly 54 for sealing the adhesive bag after the adhesive strip is torn off. During the tearing process, the clamping lifting assembly 52 first controls the clamping assembly 51 to descend and press down on the adhesive part of the adhesive bag, causing one side of the adhesive strip 101 to lift up and clamp one edge of the adhesive strip 100. Figure 1The dashed area is pressed down, the rubber strip right side is lifted, after the rubber strip 100 is clamped, the rubber strip lifting assembly 52 makes the rubber strip assembly 51 rise to a set height to avoid the rubber strip position, and the rubber strip translation assembly 53 controls the rubber strip assembly 51 to translate and tear the rubber strip, and then the sealing assembly 54 seals the rubber bag.The utility model discloses a way of pressing down the adhering part of the rubber bag to reliably lift one side of the rubber strip 101, and the rubber strip will not shake, so that the rubber strip can be reliably clamped, and the step of translating and tearing the rubber strip can simulate the effect of manual parallel tearing of the rubber strip, compared with the prior art rubber tearing device, after the rubber strip is clamped, the rubber strip 100 is lifted vertically to tear the rubber strip, and the rubber strip translation and tearing mode of the utility model can reduce the pulling of the adhering part of the rubber bag during the tearing process, so that the deformation of the adhering part of the rubber bag can be avoided, so that the flatness of the mouth of the rubber bag after sealing can be ensured.

[0028] Please refer to Figures 3 to 5 , the rubber strip assembly 51 includes a clamping plate 511, a clamping jaw 512 and a clamping jaw air cylinder 513, the clamping jaw 512 is arranged opposite to the clamping plate 511, the clamping jaw air cylinder 513 is connected with the clamping jaw 512, controls the clamping jaw 512 to open and close relative to the clamping plate 511, the bottom of the clamping plate 511 is lower than the clamping jaw 512 by a preset height, the preset height is used for pressing the adhering part (such as the dashed area of the figure) of the rubber bag, so that the rubber strip is lifted, then the clamping jaw 512 is controlled by the clamping jaw air cylinder 513 to close the clamping plate 511, one side of the rubber strip is clamped, and preparation is made for subsequent tearing of the rubber strip. Figure 1 Furthermore, the clamping jaw 512 is also provided with anti-skid lines, so that the rubber strip is not easy to fall off when clamped.

[0029] Further, the rubber strip assembly 51 includes a table plate 514, the table plate 514 has a recess (i.e. a rubber strip position), the recess (not labeled in the figure) is provided with an elastic lifting plate 5141, the descending depth of the elastic lifting plate 5141 is greater than or equal to the preset height, so as to ensure that when the clamping plate 511 is pressed down, the elastic lifting plate 5141 is pressed down to press the adhering part of the rubber bag, so that one side of the rubber strip is lifted, and at the same time, the bottom of the clamping jaw 512 can be closely attached to the table plate 514, thereby ensuring that the clamping jaw 512 can clamp the rubber strip (as shown in the figure) when closed. Figure 4 When the rubber strip lifting assembly 52 rises to a set height to avoid the rubber strip position, the elastic lifting plate 5141 is reset.

[0030] Please refer to Figures 2 to 5 , the rubber strip lifting assembly 52 includes a rubber strip lifting air cylinder 521, a lifting control rod 522, a positioning frame 523, a positioning plate 524, a lifting rod 525 and a lifting spring 526, the movable end of the rubber strip lifting air cylinder 521 and one end of the lifting control rod 522 pass through the positioning frame 523 and are connected with the clamping plate 511, one end of the lifting rod 525 and the other end of the lifting control rod 522 are connected with the positioning plate 524, and the lifting spring 526 is sleeved on the lifting rod 525 (as shown in the figure). Figure 3The positioning plate 524 and the clamp plate 511 are lowered to make the elastic lifting plate 5141 move down to the position of the rubber strip 101, and one side of the rubber strip 101 is lifted. At this time, the lifting rod 525 abuts against the positioning frame 523 to compress the lifting spring 526 (as shown in Figure 4 The clamp jaw 512 can then move to the side of the clamp plate 511 to clamp the lifted rubber strip 101. After that, the lifting spring 526 is reset to make the clamp plate 511 rise to the set height to avoid the platform 514, so as to facilitate the translation of the rubber strip.

[0031] In this embodiment, the lifting control rod 522 and the lifting rod 525 are both two, which are arranged on the two sides of the rubber strip lifting cylinder 521, so that the rubber strip lifting assembly 52 controls the rubber strip assembly 51 to rise and fall more stably. The specific operation of the rubber strip lifting assembly 52 is as follows: first, the rubber strip lifting cylinder 521 is lowered to make the clamp plate 511 descend. Since one end of the lifting control rod 522 is connected with the clamp plate 511 and the other end is connected with the positioning plate 524, when the clamp plate 511 descends, the positioning plate 524 is synchronously lowered through the lifting control rod 522. When the clamp plate 511 is lowered to make the elastic lifting plate 5141 descend to the position of the rubber strip, the lifting rod 525 abuts against the positioning frame 523. At this time, the lifting spring 526 is compressed, and the compression length is the height of the descent of the elastic lifting plate 5141. After the clamp jaw 512 clamps the rubber strip, the rubber strip lifting cylinder 521 stops supplying air (since the rubber strip lifting cylinder 521 does not supply air in the opposite direction, the rubber strip lifting cylinder 521 remains in the current state), and the clamp plate 511 rises through the reset of the lifting spring 526 to separate from the elastic lifting plate 5141, that is, to separate from the position of the rubber strip. Then, the rubber strip assembly 51 is controlled to translate through the rubber strip translation assembly 53 (as shown in Figure 5 The purpose of tearing the rubber strip is achieved.

[0032] Specifically, the rubber strip translation assembly 53 includes a rubber strip support frame 531, a sliding block 532, a sliding rail 533, and a translation cylinder 534. The sliding block 532 is arranged on the two sides of the rubber strip support frame 531. The sliding rail 533 is in sliding connection with the sliding block 532. One end of the positioning frame 523 is connected with the two sliding rails 533. The translation cylinder 534 is fixed on the rubber strip support frame 531. The movable end of the translation cylinder 534 is connected with the middle of the positioning frame 523. The rubber strip lifting assembly 52 is arranged on the positioning frame 523. In the translation process, the moving position of the rubber strip lifting assembly 52 and the rubber strip assembly 51 is controlled through the extension and contraction of the translation cylinder 534. At the same time, the rubber strip lifting assembly 52 moves more stably and reliably through the cooperation between the sliding rail 533 and the sliding block 532.

[0033] As Figures 2 to 5As shown, the glue bag tearing and sealing device 5 further comprises a bag mouth pressing assembly 55 for pressing the mouth of the glue bag, which is arranged opposite to the glue clamping assembly 51. The bag mouth pressing assembly 55 comprises a bag mouth pressing plate 551 and a bag mouth pressing cylinder 552, and the movable end of the bag mouth pressing cylinder 552 is connected with the bag mouth pressing plate 551. The bag mouth pressing assembly 55 is arranged on the glue clamping support frame 531. When the glue strip is clamped, the bag mouth pressing plate 551 is controlled to descend by the bag mouth pressing cylinder 552 to press the mouth of the glue bag, and then the clamping plate 511 is controlled to descend by the glue clamping lifting assembly 52 to press the adhering part of the glue bag, which can help the one side of the glue strip to be raised. When the clamping jaw 512 clamps the glue strip and rises to be separated from the glue clamping position, the bag mouth pressing plate 551 is always in the state of pressing the glue bag. Then, the glue clamping translation assembly 53 is moved to achieve the purpose of tearing the glue.

[0034] The glue bag tearing and sealing device 5 further comprises a glue strip recycling assembly 56 arranged on the tearing and moving side of the glue clamping assembly 51. The glue strip recycling assembly 56 comprises a glue strip recycling port 561 connected with a compressed air source (not shown in the figure). When the glue clamping assembly 51 clamps the glue strip, the glue clamping translation assembly 53 is moved along the front side of the bag mouth to separate the glue strip from the glue bag. When the glue clamping translation assembly 53 is moved to the recycling port, the compressed air generates negative pressure to suck the glue strip to achieve the purpose of recycling the glue strip, avoid the glue strip from being scattered to cause environmental pollution, and avoid affecting the subsequent packaging.

[0035] Please continue to refer to Figure 2 , Figure 6 and Figure 7 . The sealing assembly 54 comprises a glue bag pressing unit 541 arranged on the rear side of the glue clamping assembly 51 and a sealing unit 542 arranged between the glue bag pressing unit 541 and the glue clamping assembly 51. After the air in the glue bag is exhausted by the glue bag pressing unit 541, the adhering part of the torn glue strip is pasted by the glue bag pressing unit 541 cooperating with the sealing unit 542, and the fabric packaging is completed.

[0036] The bag pressing unit 541 comprises a bag pressing support frame 5411, a bag body pressing cylinder 5412, a bag mouth baffle 5413, a bag mouth leveling plate 5414, an exhaust cylinder 5415 and an exhaust pressing plate 5416. The bag body pressing cylinder 5412 is arranged on the bag pressing support frame 5411. The bag mouth baffle 5413 is connected with the movable end of the bag body pressing cylinder 5412. The bag mouth leveling plate 5414 is arranged on the bag mouth baffle 5413. The exhaust cylinder 5415 is arranged on the bag pressing support frame 5411. The exhaust pressing plate 5416 is connected with the movable end of the exhaust cylinder 5415. The exhaust cylinder 5415 is pressed downward to press the bag with the exhaust pressing plate 5416, so that the air in the bag is exhausted. Then the bag body pressing cylinder 5412 is pressed downward, so that the bag mouth baffle 5413 is pressed against the folding part of the bag, and the bag mouth leveling plate 5414 is pressed against the bag mouth, so that the bag mouth is leveled, thereby facilitating the sealing unit 542 to seal the bag.

[0037] The sealing unit 542 comprises a sealing flap 5421, a flap lifting cylinder 5422, a flap lifting frame 5423, a turning cylinder 5424 and a turning connecting rod 5425. The movable end of the flap lifting cylinder 5422 is connected with the flap lifting frame 5423. The turning cylinder 5424 is arranged on the flap lifting frame 5423. One end of the turning connecting rod 5425 is connected with the movable end of the turning cylinder 5424, and the other end of the turning connecting rod 5425 is connected with the sealing flap 5421. When the bag is sealed, the bag mouth baffle 5413 is pressed against the folding part of the bag. The flap lifting cylinder 5422 controls the flap lifting frame 5423 to be lifted, and the sealing flap 5421 is lifted synchronously, so that the folding part of the bag is lifted. Then the bag body pressing cylinder 5412 is lifted, so that the bag mouth leveling plate 5414 and the bag mouth baffle 5413 are separated from the bag. Then the turning cylinder 5424 is operated, and the sealing flap 5421 is turned through the turning connecting rod 5425, so that the part with adhesive is attached to the bag mouth, thereby completing the sealing operation.

[0038] In order to ensure the normal operation of each component, the bag tearing and sealing device 5 further comprises a plurality of conveying components (not numbered in the figure) for conveying the bag and a detection component (such as a photoelectric sensor, a camera, etc.) for detecting the position of the bag. The detection component is used to identify the position of the identification line and control the stop position of the conveying component according to the detection result. The conveying component and the detection component can ensure that the bag is conveyed to the specified position, so that other components can complete the specified action. The conveying component can also be driven to rotate by a motor to convey the bag 100. Therefore, the conveying position of the bag 100 can be controlled by controlling the rotation angle of the motor, so that the bag clamping and sealing position can be accurately controlled.

[0039] In order to make the technical scheme of the glue bag tearing and sealing device 5 provided by the utility model more clear, the following will be combined with Figures 1 to 7 The working mode of the glue bag tearing and sealing device is described in detail.

[0040] When the gluing action is performed, the detector detects the position of the identification line 102 on the glue bag 100 to position the glue strip 101, and the transmission state of the transmission device is controlled according to the detection result. When the glue strip reaches the groove of the platform 514, the bag opening compression assembly 55 is used to compress the bag opening of the glue bag first, and then the gluing lifting assembly 52 is used to control the gluing assembly 51 to descend. At this time, the clamping plate 511 presses the elastic lifting plate 5141 to descend and compresses the fitting part of the glue bag 100, so that the height of the fitting part is lower than the part of the glue strip that is not compressed. That is, by pressing a part of the glue strip and the fitting part, one side of the glue strip is raised. Then, the clamping jaw 512 is controlled to clamp one side of the glue strip. Compared with the mode of raising the glue strip by blowing, the glue strip will not shake when it is raised, so that the clamping of the clamping jaw is more reliable.

[0041] After the clamping jaw 512 is tightened, the gluing lifting cylinder 521 stops supplying air, and the clamping plate 511 is lifted by the reset of the lifting spring 526, so that the clamping plate 511 is separated from the elastic lifting plate 5141, that is, the height of the gluing position is separated.

[0042] Then, the gluing translation assembly 53 is used to control the gluing assembly 51 to translate, that is, the tearing effect is achieved. When the clamping jaw 512 is moved to the glue strip recycling assembly 56 by the gluing translation assembly 53, the glue strip is sucked and recycled through the glue strip recycling opening 561, so that the purpose of recycling the glue strip is achieved.

[0043] Then, the glue bag is conveyed to the sealing assembly 54 through the conveying assembly, the exhaust cylinder 5415 is pressed down, the exhaust pressing plate 5416 is used to compress the glue bag, the air in the glue bag is exhausted, the bag body compression cylinder 5412 is pressed down, the bag opening stop plate 5413 is used to press against the folding part of the fitting part of the glue bag, and the bag opening flattening plate 5414 is used to compress the bag opening of the glue bag, so that the effect of flattening the bag opening is achieved, and the glue bag is sealed by the sealing unit 542.

[0044] Finally, the bag opening stop plate 5413 is used to press against the folding part of the fitting part of the glue bag, the flap lifting cylinder 5422 is used to control the flap lifting frame 5423 to rise and the sealing flap 5421 to rise synchronously, so that the fitting part of the glue bag is erected, the bag body compression cylinder 5412 is lifted, the bag opening flattening plate 5414 and the bag opening stop plate 5413 are separated from the fitting part of the glue bag, and finally the turnover cylinder 5424 is operated to make the sealing flap 5421 turn over through the turnover connecting rod 5425, so that the part with glue is attached to the fitting part of the glue bag, that is, the sealing operation is completed.

[0045] After the above steps, the tearing and sealing operations of the glue bag are completed, and the whole process does not need manual operation, so that automatic operation is realized.

[0046] In summary, the adhesive bag tearing and sealing device provided by the utility model can simulate the effect of manual parallel tearing of the adhesive strip, and the parallel tearing method can reduce the pulling of the bonding part of the adhesive bag during the tearing process, so that the deformation of the bonding part of the adhesive bag can be avoided, and the flatness of the mouth part of the adhesive bag after sealing can be ensured. Moreover, the adhesive strip will not shake when it is raised, compared with the method of clamping the adhesive strip by blowing, the utility model improves the reliability of the tearing operation and has high tearing efficiency.

[0047] At the same time, the adhesive bag tearing and sealing device provided by the utility model does not need manual participation in the whole tearing and sealing process, is completely automated, and improves the production efficiency.

[0048] It can be understood that, for those skilled in the art, equivalent replacement or change can be made according to the technical scheme and the utility model concept of the utility model, and all these changes or replacements shall belong to the protection scope of the claims attached to the utility model.
