Description

Technical Field

[0001] The utility model relates to the technical field of plastic bag packaging, in particular to a plastic bag packaging bundling device. Background Art

[0002] Plastic bags refer to packaging bags made of plastic as raw material, mainly used to hold and load items. They are widely used due to their low cost, extremely light weight, large capacity, and easy storage. During the production and transportation of plastic bags, strapping tape and rope are usually used to bundle plastic bags from the same batch to prevent them from becoming scattered and difficult to organize.

[0003] Utility model publication number CN112009798A discloses a packaging bag bundling method that bundles different parts of the bag twice or more. Compared to the conventional single-bundling method, this method can achieve a tighter bundling and prevent it from becoming untidy. The bundling method is particularly effective when bundling the ends, which are prone to upward tilt and becoming untidy. The packaging bags bundled using the method of the present invention are more convenient for subsequent stacking, packaging, and transportation.

[0004] However, the above-mentioned packaging and bundling device still has the following problems during actual use: although the objects are bundled by the movable crawler and the bundling frame, when the existing plastic bags are stacked together, they are prone to sliding and tipping due to their smooth surface. Therefore, when the plastic bags are moved by the movable crawler, they are prone to slipping. At the same time, each single bundling is likely to cause the other side of the plastic bag to tilt up, resulting in misalignment and wrinkles during bundling, affecting the subsequent use of the plastic bags.

[0005] Therefore, we propose a plastic bag packaging strapping device to solve the above problems. Utility Model Content

[0006] The purpose of the utility model is to provide a plastic bag packaging and bundling device, which solves the problem that the existing bundling device uses a movable crawler and a bundling frame to bundle objects, but when the existing plastic bags are stacked together, they are prone to sliding and tipping due to their smooth surface. Therefore, when the plastic bags are moved by the movable crawler, they are prone to slipping. At the same time, each single bundling is likely to cause the other side of the plastic bag to tilt up, thereby causing misalignment and wrinkles during bundling, which affects the subsequent use of the plastic bags.

[0007] To achieve the above-mentioned object, the present invention provides the following technical solution: a plastic bag packaging and bundling device, comprising a device body and a drive cavity provided inside the device body, wherein two-way threaded rods are rotatably provided on the left and right sides of the drive cavity via bearings, and guide threaded rods are rotatably provided on the left and right sides of the middle portion of the drive cavity via bearings;

[0008] The device further comprises: a tidying mechanism is provided on the left and right sides of the top surface of the device body, and the tidying mechanism includes a guide frame, and the guide frame is fixedly installed on the left and right sides of the top surface of the device body;

[0009] Among them, the left and right sides of the top surface of the device body are provided with a bundling mechanism, and the bundling mechanism includes a bundling base, and the rear ends of the left and right bundling bases are fixedly provided with a bundling discharge roller.

[0010] Preferably, the front ends of the bidirectional threaded rods in the internal driving cavity of the device body are meshed and connected to each other through a sprocket mechanism, and the front end of the left bidirectional threaded rod is fixedly connected to the output shaft end of the servo motor, and the middle parts of the left and right bidirectional threaded rods are meshed and connected to the inner ends of the guide threaded rods through a bevel gear group, and the length of the guide threaded rod is equal to 1 / 2 of the length of the bidirectional threaded rod.

[0011] Preferably, the tidying mechanism includes a tidying resistance plate, and the tidying resistance plate is slidably arranged on the top surface of the left and right guide frames in a front-to-back symmetrical manner, and the middle parts of the outer ends of the front and rear tidying resistance plates are rotatably connected to the inner end of the one-way flip plate through a torsion spring, and the one-way flip plate is used to prevent obstruction between the tidying mechanism and the bundling mechanism.

[0012] Preferably, the regularization mechanism includes a guide slider, and the guide slider is threadedly connected to the outside of the left and right bidirectional threaded rods in a front-to-back symmetrical manner, and the middle part of the symmetrically arranged guide slider slides through the interior of the guide frame, and the top end of the symmetrically arranged guide slider is elastically connected to the outer end of the telescopic slide rod, and at the same time, the inner end of the symmetrically arranged telescopic slide rod is fixedly connected to the regularization contact plate.

[0013] Preferably, the bundling mechanism includes a bundling frame, and the bundling frame is fixedly installed on the top surface of the left and right bundling bases, and the bottom ends of the left and right bundling bases are threadedly connected to the outer wall of the guide threaded rod, and the bundling base is used to tighten and limit the bundling belt of the outer end bundling discharge roller.

[0014] Preferably, the strapping mechanism includes a limiting wheel, and the limiting wheel is symmetrically arranged on the left and right and rotates at equal distances inside the strapping frame, and the strapping belt is limited inside the strapping frame by the limiting wheel installed on the left and right. After the strapping belt is tightened by the strapping base of the strapping mechanism, the strapping belt can be detached downward through the middle of the limiting wheels on the left and right sides so that it can be put on the outside of the plastic bag to achieve strapping.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: the plastic bag packaging and bundling device uses the regularization contact plate and the one-way flip plate of the regularization mechanism above the device body to regularize and limit the plastic bag, and the bundling frame included in the bundling mechanism is used to put the internal bundling belt on both ends of the plastic bag and tighten it so as to be bundled at the left and right ends of the plastic bag. The synchronous bundling and limiting can prevent one end from tilting and deflecting. The specific contents are as follows:

[0016] 1. The plastic bags are detached through the guide frame at the top of the device body. The bidirectional threaded rod then drives the guide slider to move inside the guide frame, which in turn drives the regular contact plate at its top elastically connected by the telescopic slide rod to slide inward synchronously. The regular contact plate and the one-way flip plate fit the front and back sides of the plastic bags, thereby preventing them from slipping when stacked.

[0017] Furthermore, a one-way flip plate is hinged to the outer end of the regular contact plate by a torsion spring, and can follow the regular contact plate to fit the front and rear sides of the plastic bag, thereby ensuring the regular effect of limiting the position of the plastic bag. At the same time, after the strapping mechanism completes strapping of the plastic bag, the one-way flip plate can drive the hinged one-way flip plate to flip inward synchronously through the outward movement of the regular contact plate, and separate from the strapping belt and the plastic bag, thereby ensuring the strapping effect of the strapping belt on the plastic bag and preventing the plastic bag from being shifted and dislocated.

[0018] 2. The bidirectional threaded rod drives the guide threaded rod to rotate through the bevel gear group, and the guide threaded rod drives the threaded strapping base to move, and then the strapping frame moves to the outside of the plastic bag, and the strapping belt guided by the limiting wheel inside the strapping frame is tightened, so that the strapping belt is detached from the middle of the limiting wheels on the left and right sides so that it can be put on the left and right ends of the plastic bag. Through the synchronous strapping limit, the situation of one end tilting and offsetting is prevented. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the implementation regulations described 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.

[0027] See also Figures 1-6 , the utility model provides the following technical solutions:

[0028] Example 1: To address the problems existing in existing strapping devices during use, this embodiment adopts the following technical solution: a plastic bag packaging strapping device, comprising a device body 1, and a drive cavity 2 provided within the device body 1, wherein bidirectional threaded rods 3 are rotatably provided on the left and right sides of the drive cavity 2 via bearings, the front ends of the bidirectional threaded rods 3 in the drive cavity 2 within the device body 1 being meshed and connected to each other via a sprocket mechanism 8, and the front end of the left bidirectional threaded rod 3 is fixedly connected to the output shaft end of a servo motor 9;

[0029] The left and right sides of the top surface of the device body 1 are provided with a regularizing mechanism, and the regularizing mechanism includes a guide frame 5, and the guide frame 5 is fixedly installed on the left and right sides of the top surface of the device body 1; the regularizing mechanism includes a regularizing contact plate 11, and the regularizing contact plate 11 is slidably arranged on the top surfaces of the left and right guide frames 5 in a front-to-back symmetrical manner, and the middle parts of the outer ends of the front and rear regularizing contact plates 11 are rotatably connected to the inner ends of the one-way flip plates 12 by torsion springs, and the one-way flip plates 12 prevent obstruction between the regularizing mechanism and the bundling mechanism; the regularizing mechanism includes a guide slider 13, and the guide slider 13 is threadedly connected to the outside of the left and right bidirectional threaded rods 3 in a front-to-back symmetrical manner, and the middle parts of the symmetrically arranged guide sliders 13 slide through the inside of the guide frame 5, and the top ends of the symmetrically arranged guide sliders 13 are elastically connected to the outer ends of the telescopic slide rods 14, and the inner ends of the symmetrically arranged telescopic slide rods 14 are fixedly connected to the regularizing contact plates 11;

[0030] like Figure 2-Figure 3 As shown, when it is necessary to regularize and limit the plastic bags, the plastic bags are first placed above the guide frames 5 on the left and right sides of the top surface of the device body 1, and the plastic bags are lifted by the guide frames 5. Then the servo motor 9 drives the bidirectional threaded rod 3 engaged by the sprocket mechanism 8 to rotate inside the driving cavity 2, so as to drive the guide sliders 13 threadedly connected on the front and rear sides to slide synchronously inward along the direction of the guide frame 5, and then the guide slider 13 drives the regular contact plate 11 elastically connected at the top by the telescopic slide rod 14 to slide inward so as to fit to the front and rear outer walls of the plastic bag, thereby regularizing and limiting the plastic bags to prevent them from slipping when stacked, and then the one-way flip plate 12 installed on the outer end of the regular contact plate 11 is rotated by the torsion spring to fit the outside of the plastic bag synchronously. The rotation of the one-way flip plate 12 can disengage from the limit of the strapping mechanism to prevent obstruction between the regular mechanism and the strapping mechanism.

[0031] Example 2: In order to solve the problems existing in the use of existing strapping devices, this embodiment adopts the following technical solutions: guide threaded rods 4 are rotatably provided on the left and right sides of the middle portion of the driving cavity 2 through bearings, and the middle portions of the left and right bidirectional threaded rods 3 are meshed and connected to the inner ends of the guide threaded rods 4 through bevel gear sets 10, and the length of the guide threaded rods 4 is equal to 1 / 2 of the length of the bidirectional threaded rods 3; wherein, strapping mechanisms are provided on the left and right sides of the top surface of the device body 1, and the strapping mechanisms include strapping bases 6, and strapping unloading rollers 7 are fixedly provided at the rear ends of the left and right strapping bases 6;

[0032] The strapping mechanism includes a strapping frame 15, and the strapping frame 15 is fixedly installed on the top surface of the strapping base 6 on the left and right sides, and the bottom ends of the strapping base 6 on the left and right sides are threadedly connected to the outer wall of the guide threaded rod 4, and the strapping base 6 is used to tighten and limit the strapping belt of the outer end strapping discharge roller 7; the strapping mechanism includes a limiting rotary wheel 16, and the limiting rotary wheel 16 is symmetrically arranged on the inside of the strapping frame 15 and rotates at equal distances, and the strapping belt is limited to the inside of the strapping frame 15 by the limiting rotary wheel 16 installed on the left and right sides, and after the strapping belt is tightened by the strapping base 6 of the strapping mechanism, the strapping belt can be detached downward through the middle of the limiting rotary wheels 16 on the left and right sides, so that it can be sleeved on the outside of the plastic bag to achieve strapping;

[0033] like Figure 4-Figure 6As shown, during the operation of the regularization mechanism, the rotating bidirectional threaded rod 3 drives the meshing guide threaded rods 4 on the left and right sides to rotate through the middle bevel gear group 10, and then the guide threaded rod 4 drives the strapping base 6 threadedly connected to the outer wall and the strapping discharge roller 7 at the rear end to move synchronously toward the two ends of the plastic bag, and then the strapping frame 15 installed on the top surface of the strapping base 6 moves to the outside of the plastic bag, so that the strapping base 6 can tighten the strapping belt guided by the limiting wheel 16 inside the strapping frame 15, so that the strapping belt is detached from the middle of the limiting wheels 16 on the left and right sides, so that it can be put on the left and right ends of the plastic bag. Through the synchronous strapping limit, the situation of one end tilting and deflecting is prevented;

[0034] Furthermore, when the strapping belt is put on the left and right ends of the plastic bag, the regularization contact plate 11 is driven to slide synchronously outward by the regularization mechanism, and then the one-way flip plate 12 limited inside the strapping belt moves outward with the regularization contact plate 11. It is hingedly connected by a torsion spring so that it can be detached from the strapping belt after flipping, thereby preventing the strapping belt from slipping off at both ends when strapping the plastic bag.
