DETAILED DESCRIPTION

[0041] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only 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 ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0042] Depend on Figure 1-11The present invention discloses a detection device for paper-plastic bag production and a method for using the same, comprising a supporting shell 1. After the paper-plastic bag is made, a conveyor belt in the supporting shell 1 conveys the paper-plastic bag. A bracket 2 is fixedly connected to the supporting shell 1. A pressing roller 3 is rotatably arranged on the bracket 2. A guiding structure and a stretching structure are sequentially arranged on one side of the pressing roller 3.

[0043] The end surface of the pressing roller 3 is provided with a table 7, and a rotating shaft 8 is fixedly connected to the table 7, and the rotating shaft 8 is arranged on the bracket 2. The interior of the pressing roller 3 is a hollow structure, and a slot 12 is opened on the surface of the pressing roller 3. The paper-plastic bag can be adsorbed by the slot 12 and rotate with the pressing roller 3.

[0044] The guide structure includes a guide block 4 and a limit plate 14, which are arranged in parallel up and down. A notch 15 is provided on one end of the guide block 4, and the side walls of the notch 15 extend to both sides of the pressure roller 3. The guide block 4 is located below the limit plate 14, and the end of the guide block 4 facing the pressure roller 3 is longer than the end of the limit plate 14 facing the pressure roller 3, so that the end of the paper-plastic bag can enter between the guide block 4 and the limit plate 14, and a first gap is provided between the guide block 4 and the limit plate 14, and the paper-plastic bag can slide along the first gap and pass through the first gap.

[0045] The stretching structure includes a fixing frame 5, and two symmetrically arranged bite mechanisms are arranged inside the fixing frame 5. The bite mechanisms include an upper clamping block 23 and a lower clamping block 20. A second gap is provided between the upper clamping block 23 and the lower clamping block 20. After the paper-plastic bag passes through the first gap, it can enter the second gap and be located between the upper clamping block 23 and the lower clamping block 20. Then, the upper clamping block 23 and the lower clamping block 20 can fit each other to bite and fix the edge of the paper-plastic bag.

[0046] After the paper-plastic bag is produced and cut, a conveyor belt is provided inside the supporting shell 1 to convey the paper-plastic bag. During the conveying process, the pressing roller 3 can press the paper-plastic bag 3 tightly. When the paper-plastic bag needs to be sampled, the slot 12 adsorbs the paper-plastic bag, and the adsorbed paper-plastic bag rotates with the pressing roller 3 to the guide structure. At this time, the paper-plastic bag slides on the guide structure and enters the stretching structure, and the paper-plastic bag is subjected to stretching detection in the stretching structure.

[0047] The steps for using this device are as follows:

[0048] In the first step, when the paper-plastic bag needs to be sampled, the slot 12 is used to absorb the paper-plastic bag;

[0049] In the second step, the paper-plastic bag adsorbed by the slot 12 rotates together with the pressing roller 3;

[0050] In the third step, after one side of the paper-plastic bag is placed on the upper end of the guide block 4, the paper-plastic bag slides on the upper surface of the guide block 4;

[0051] Step 4: the paper-plastic bag passes through the first gap into the stretching structure and is fixed by the upper clamping block 23 and the lower clamping block 20;

[0052] Step 5: the paper-plastic bag moves with the upper clamping block 23 and the lower clamping block 20, and during the movement, the tensile properties of the paper-plastic bag are tested;

[0053] Step 6: The upper clamping block 23 and the lower clamping block 20 are reset.

[0054] A first telescopic member 9 is arranged inside the pressure roller 3, and a fixed end of the first telescopic member 9 is fixedly connected to the inside of the pressure roller 3. A fixing plate 10 is fixedly connected to the telescopic end of the first telescopic member 9, and a support column 11 is fixedly connected to a side of the fixing plate 10 away from the first telescopic member 9. The support column 11 is inserted into the slot 12, and a suction cup 13 is arranged on the support column 11.

[0055] There are multiple slots 12 , which are longitudinally arranged on the surface of the pressure roller 3 .

[0056] When the above solution is implemented, the first telescopic member 9 pushes the suction cup 13 toward the outside of the slot 12. When the suction cup 13 is pressed against the surface of the paper-plastic bag, since the surface of the paper-plastic bag has a thin film, the suction cup can be adsorbed on the surface of the paper-plastic bag, thereby picking up the paper-plastic bag.

[0057] The first telescopic member 9 may be controlled by a control module or by a switch, and this application does not impose any limitation thereto.

[0058] The limiting plate 14 , the guide block 4 and the fixing frame 5 are fixedly connected to the supporting shell 1 via the supporting rod 6 .

[0059] The fixing frame 5 is in a concave structure, and a sliding seat 16 is arranged in the side wall of the fixing frame 5. A threaded rod 17 is arranged running through the sliding seat 16. The threaded rod 17 and the sliding seat 16 are threadedly matched so that when the threaded rod 17 rotates, the sliding seat 16 can slide. The threaded rod 17 is driven by a motor. A mounting groove is provided in the sliding seat 16, and a fixing block 22 is installed in the mounting groove. The upper clamping block 23 is installed on the fixing block 22. The lower clamping block 20 and the fixing block 22 can both slide left and right in the mounting groove, and the sides of the lower clamping block 20 and the fixing block 22 are both provided with a spring 21. A first groove is provided at the upper end of the lower clamping block 20, and an insertion block is provided at the lower end of the upper clamping block 23. The insertion block can enter the first groove, so as to bite and fix the edge of the paper-plastic bag. In order to ensure the stability of the fixation, a rubber sheet (not shown in the figure) can also be provided on the contact surface to increase the friction and ensure the stability.

[0060] In some embodiments, a second groove is formed at the lower end of the fixed block 22, and a second telescopic rod 24 is arranged in the second groove. The fixed end of the second telescopic rod 24 is fixedly connected to the inner wall of the second groove. The telescopic end of the second telescopic rod 24 faces downward and is fixedly connected to the upper clamping block 23. In this embodiment, the extension and retraction of the second telescopic rod 24 can be achieved by remote control.

[0061] In some other embodiments, a through hole is opened in the fixing block 22, and a positioning rod 25 is arranged in the through hole. The upper end of the positioning rod 25 is inserted into the positioning groove 26, and the positioning groove 26 is arranged in the fixing frame 5. The lower end of the positioning rod 25 is fixedly connected to the upper clamping block 23. The positioning groove 26 has a high section and a low section. When the positioning rod 25 slides in the high section, the upper clamping block 23 is separated from the lower clamping block 20. When the positioning rod 25 slides in the low section, the upper clamping block 23 and the lower clamping block 20 are tightly attached to fix the edge of the paper-plastic bag, and the positioning rod 25 can also slide in the positioning groove 26 and in the lateral direction of the positioning groove 26. In this embodiment, the downward movement of the positioning rod 25 is achieved by the shape of the positioning groove 26, which can be more stable during implementation.

[0062] A support platform 19 is arranged between the two bite mechanisms, and the support platform 19 is bent upward and bulged. A pressure sensor 27 is arranged on the sliding seat 16. After sliding, the lower clamping block 20 can press against the pressure sensor 27. When the bite mechanism bites the two ends of the paper-plastic bag, as the bite mechanism moves, the middle part of the paper-plastic bag is pushed upward by the support platform 19. At this time, the lower clamping block 20 and the fixed block 22 can be pulled to one side and press against the pressure sensor 27. When the paper-plastic bag is pushed upward to the limit position by the support platform 19, the paper-plastic bag 19 breaks or cracks, and the pressure sensor 27 can record the pressure so as to judge the quality of the paper-plastic bag.

[0063] The lower clamping block 20 and the fixed block 22 are respectively provided with guide rails penetrating therein, and the guide rails are arranged transversely. The lower clamping block 20 and the fixed block 22 can slide along the guide rails, and their sliding directions are limited.
