Technical Field

[0001] This utility model relates to the technical field of bubble wrap packaging bag positioning and pressing devices, and in particular to a bubble wrap packaging bag positioning and pressing device to prevent bubble rupture. Background Technology

[0002] Bubble wrap is a common protective packaging material, typically used to package fragile items to prevent damage during transportation or storage. The outer layer of bubble wrap is made of plastic, while the inner layer consists of densely packed air bubbles. These bubbles provide additional cushioning, reducing the impact and pressure on the items. Bubble wrap is lightweight, flexible, and possesses high toughness and durability, making it a practical packaging material widely used across various industries.

[0003] A search revealed Chinese Patent Publication No. CN220262186U, which discloses a positioning and pressing device for bubble wrap packaging bags to prevent bubble rupture. The device includes a base, a traveling mechanism fixedly mounted on the base, and an adjusting mechanism fixedly mounted on the traveling mechanism. An upper pressing roller is movably engaged on one side of the adjusting mechanism. In use, this device uses a knob to drive a lower screw to drive a first pressing roller to press the bubble wrap packaging bag. However, this structure requires simultaneous adjustment of the screws at both ends of the first pressing roller, making the operation cumbersome and time-consuming, significantly reducing efficiency. Furthermore, this structure lacks a guiding mechanism for the bubble wrap packaging bag, making it prone to misalignment and affecting packaging quality, thus failing to meet usage requirements. Therefore, this paper proposes a positioning and pressing device for bubble wrap packaging bags to prevent bubble rupture and address these issues. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a positioning and pressing device for bubble wrap packaging bags to prevent bubble rupture, thus solving the problems mentioned in the background art.

[0026] Example

[0027] like Figures 1 to 5 As shown, this utility model provides a technical solution: a positioning and pressing device for bubble wrap packaging bags to prevent bubble rupture, including a fixed base 1, which serves as the basic support platform of the device. Two movable frames 2 are movably installed on the top of the fixed base 1. A roller 3 is rotatably installed on the inner side of the movable frame 2. The roller 3 serves as the bottom support roller of the bubble wrap packaging bag and directly contacts the bottom surface of the bag.

[0028] A pressure roller assembly 4, extending through to the top of the movable frame 2, is movably installed inside the frame 2. The pressure roller assembly 4 includes a movable frame 41, which is movably installed between the two sides of the inner wall of the movable frame 2. Two guide posts 411, extending through to the top of the movable frame 2, are fixedly installed on the top of the movable frame 41. A pressure roller 42 is rotatably installed on the inner side of the movable frame 41. The cooperation between the movable frame 41 and the guide posts 411 ensures that the pressure roller 42 adjusts its height only in the vertical direction, avoiding uneven pressing caused by offset. A sponge sleeve 43 is fixedly installed on the outer side of the pressure roller 42. An adjusting cylinder 44, extending through to the top of the movable frame 2, is fixedly connected to the top of the movable frame 41. A fixed frame 45 is fixedly installed on the top of the movable frame 2. A threaded rod 46 extending to the top of the fixed frame 45 and rotatably connected to it is installed on the internal thread of the adjusting cylinder 44. A rotary knob 461 is fixedly connected to the top of the threaded rod 46. This bubble wrap packaging bag positioning and pressing device, which prevents bubble rupture, adopts a threaded transmission structure between the threaded rod 46 and the adjusting cylinder 44 by setting the pressure roller assembly 4. With the guide column 411 on the top of the movable frame 41, the height of the pressure roller 42 can be adjusted synchronously by simply rotating the rotary knob 461. This avoids the cumbersome operation of adjusting the screws at both ends of the pressure roller separately in the traditional structure, and greatly simplifies the pressing force adjustment process.

[0029] A telescopic assembly 5 is movably installed on the outer side of the idler roller 3. The telescopic assembly 5 includes several movable columns 51, which are movably installed on the outer side of the idler roller 3 and extend into its interior. A rubber pad 52 is fixedly connected to one end of the movable column 51 on the outer side of the idler roller 3, and a telescopic spring 53 is fixedly connected to the other end of the movable column 51 on the interior side of the idler roller 3. When the film bag thickness is uneven or encounters a protrusion, the telescopic spring 53 can be compressed or rebounded to adapt. This bubble wrap packaging bag positioning and pressing device, which prevents bubble rupture, provides elastic cushioning when the idler roller 3 contacts the film bag by setting the movable columns 51 of the telescopic assembly 5, the telescopic spring 53 and the rubber pad 52, thus avoiding damage to the bubble wrap due to rigid compression of the idler roller 3.

[0030] A guide assembly 6 extending to the outside of the idler roller 3 is movably installed on the inner bottom wall of the movable frame 2. The guide assembly 6 includes a guide plate 61, which is slidably installed on the inner bottom wall of the movable frame 2 and extends to both sides of the pressure roller 42. The inner side of the guide plate 61 is provided with a movable groove 611 that is adapted to the pressure roller 42 and the idler roller 3. The guide plate 61 constrains the conveying path of the film bag and prevents the film bag from shifting left and right when entering between the pressure roller 42 and the idler roller 3. The outer side of the guide plate 61 is threaded with a stud 62 that is threaded to the inner bottom wall of the movable frame 2. A number of equally spaced threaded grooves 621 that are adapted to the stud 62 are provided on one side of the inner bottom wall of the movable frame 2. A knob 63 is fixedly connected to one end of the stud 62 located on the outside of the guide plate 61. The guide plate 61 of the guide assembly 6 slides with the threaded groove 621 of the inner bottom wall of the movable frame 2 through the stud 62, which can quickly adjust the guiding position on both sides to adapt to bubble wrap packaging bags of different widths.

[0031] A control mechanism 7 is fixedly installed on the top of the fixed base 1 and fixedly connected to both sides of the movable frame 2. The control mechanism 7 includes two support blocks 71, which are fixedly installed on the top of the fixed base 1 and located on both sides of the movable frame 2. A slide rail 72 is fixedly installed on the top of the support blocks 71. A rack plate 73 is fixedly installed on the opposite sides of the two support blocks 71. A slider 74 that is slidably connected to the slide rail 72 is fixedly installed on both sides of the movable frame 2. A drive motor 75 is fixedly installed on one side of one of the two sliders 74 on each side. The output shaft of the drive motor 75 is fixedly connected to a transmission gear 76 that meshes with the rack plate 73. By starting the drive motor 75 of the control mechanism 7, its output shaft drives the transmission gear 76 to rotate. Through meshing with the rack plate 73 on the outer side of the support block 71, the movable frame 2 is pushed to translate along the slide rail 72, thereby realizing the automatic translation of the movable frame 2. This structure adopts the technology known in the prior art.

[0032] The working process of this utility model:

[0033] Step 1: When the device is working, first adjust the guide component 6 according to the width of the bubble wrap bag: rotate the knob 63 to drive the stud 62 to rotate, and the guide plate 61 slides along the bottom wall of the moving frame 2 to the target position until the guide plates 61 on both sides are in contact with the sides of the bubble wrap bag, thus completing the guiding and positioning of the bag conveying path.

[0034] Step 2: Under the contact pressure of the film bag, the movable column 51 retracts into the roller 3 through the telescopic component 5 on the outside of the roller 3, the telescopic spring 53 is compressed and releases its elastic force, and the rubber pad 52 lightly touches the bottom surface of the film bag to provide cushioning support. With the synergistic cushioning of the sponge sleeve 43, the film bag is prevented from deforming due to hard contact.

[0035] Step 3: Drive the threaded rod 46 to rotate by rotating the knob 461 of the rotating pressure roller assembly 4, so that the adjusting cylinder 44 moves down and drives the movable frame 41 to move vertically along the guide column 411 until the sponge sleeve 43 on the outside of the pressure roller 42 lightly presses the top surface of the film bag, and cooperates with the support roller 3 to complete the positioning and pressing of the bubble film.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
