Description

Technical Field

[0001] This utility model belongs to the field of packaging bag production technology, specifically relating to a non-woven packaging bag clamping mechanism. Background Technology

[0002] Nonwoven bag clamping refers to the operation of clamping, fixing, and positioning packaging bags using a specific clamping mechanism during the production, packaging, or transportation of nonwoven packaging bags. Its purpose is to prevent the packaging bags from moving, shaking, or shifting during filling, sealing, and printing processes, ensuring smooth production flow, guaranteeing packaging quality and stability, and improving production efficiency. It is an indispensable and crucial link in the automated production process of nonwoven packaging bags.

[0003] Chinese patent application 202222609708.X discloses a bag clamping mechanism for packaging bag production. The key technical features are: a worktable and a transmission assembly. The transmission assembly includes a mounting frame, positive and negative threaded screws, an upper slider, a lower slider, an upper rotating component, and a lower rotating component. Two mounting frames are respectively distributed opposite each other on both sides of the worktable. Positive and negative threaded screws are rotatably connected to both sides of the two mounting frames. Each positive and negative threaded screw is connected to an upper slider and a lower slider, respectively. The upper rotating component is connected to the upper slider, and the lower rotating component is connected to the lower slider. The upper and lower sliders follow the forward and reverse rotation of the positive and negative threaded screws, moving relative to or in opposite directions on the mounting frame. The upper and lower rotating components move relative to or in opposite directions, thereby changing the spacing. The packaging bags are conveyed by the upper and lower rotating components, making it suitable for conveying packaging bags of various thicknesses and more practical.

[0004] Regarding the above and existing related technologies, the inventors believe that the following defects often exist: In the above case, multiple driving components are used to complete the adjustment operation. However, in actual operation, it is difficult for multiple driving components to be completely synchronized. This asynchrony will have an adverse effect on the adjustment quality, resulting in the adjustment effect failing to meet the expected standard. In addition, since the various driving components are interconnected and work together, when one driving component fails, it will affect the operation of the entire device, and may even cause the entire device to malfunction.

[0022] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0023] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0024] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0025] Example

[0026] Reference Figure 1-5 This is an embodiment of the present utility model, which provides a non-woven packaging bag clamping mechanism, including a base 101, a clamping assembly 102 disposed on the top of the base 101 for clamping the packaging bag, and a limiting assembly 103 disposed on the top of the base 101 for limiting the packaging bag.

[0027] The bag clamping assembly 102 avoids the need for multiple driving components, which are prone to asynchrony during adjustment. Furthermore, if one of them fails, the entire device may malfunction. The bag clamping assembly 102 solves the inconvenience caused by multiple driving components and improves the reliability of the device operation.

[0028] Specifically, the bag clamping assembly 102 includes a fixing plate 102a fixedly installed on the top of the base 101, a disassembly plate 102b snapped onto the top of the base 101, two rotating rods rotatably installed between the fixing plate 102a and the disassembly plate 102b, a first conveying wheel 102c and a second conveying wheel 102d respectively fixedly installed on the surfaces of the two rotating rods, an adjusting cylinder 102e sleeved on the surface of the second conveying wheel 102d, a driving gear 102f and a driven gear 102g respectively fixedly installed at the ends of the two rotating rods, and a first motor 102h for providing power.

[0029] The bag clamping assembly 102 eliminates the need for multiple drive components for adjustment. In actual operation, using multiple drive components often leads to problems. Firstly, it's difficult to achieve perfect synchronization between multiple drive components, and this asynchrony can cause incoordination in the operation of different parts of the device, affecting overall efficiency and effectiveness. Secondly, if one drive component fails, the interconnectedness of the drive components can prevent the entire device from operating normally. This not only increases the difficulty and cost of equipment maintenance but also severely impacts production. The bag clamping assembly 102 eliminates the inconvenience of multiple drive component adjustment, using only one drive component, making the device more stable and reliable. This optimized design allows the device to operate more efficiently, reducing downtime and malfunctions caused by drive component issues, thereby improving the overall reliability of the device.

[0030] Furthermore, the driving gear 102f and the driven gear 102g mesh, and the output end of the first motor 102h is fixedly connected to the surface of the driving gear 102f.

[0031] Preferably, the bag clamping assembly 102 also includes a limiting strip 102i fixedly installed on the surface of the second conveying wheel 102d, and a groove 102j opened inside the adjusting cylinder 102e and used in conjunction with the limiting strip 102i.

[0032] The limiting strip 102i and the groove 102j are used to position and install the adjusting cylinder 102e, so as to prevent the adjusting cylinder 102e from rotating relative to the second conveying wheel 102d during use, which would affect the clamping effect and conveying efficiency of the packaging bag.

[0033] Furthermore, a mounting block 102k is fixedly installed on the bottom of the disassembly plate 102b, and a mounting groove for use with the mounting block 102k is opened on the top of the base 101. A side plate is fixedly installed on the surface of the disassembly plate 102b, and the side plate is fixedly installed on the top of the base 101 by mounting bolts.

[0034] The mounting block 102k and the mounting groove facilitate the installation and removal of the disassembly plate 102b, thereby facilitating the replacement of the adjusting cylinder 102e and adjusting the distance between the adjusting cylinder 102e and the first conveying wheel 102c, thus enabling the clamping and limiting of different types and specifications of packaging bags.

[0035] Specifically, the surface of the disassembly plate 102b has two grooves for use with the rotating rod, and the end of the rotating rod is engaged inside the grooves.

[0036] The groove is used to limit the end of the rotating rod, so as to avoid affecting the normal rotation of the rotating rod.

[0037] Furthermore, the limiting assembly 103 includes a fixing frame 103a fixedly installed on the top of the base 101, a horizontal plate 103b fixedly installed on the inner side of the fixing frame 103a, two clamping plates 103c slidably installed on the inner side of the fixing frame 103a, a connecting frame 103d fixedly installed on the outer side of the clamping plate 103c, a second motor 103e fixedly installed on the top of the fixing frame 103a, and a screw 103f fixedly installed on the output end of the second motor 103e and threadedly connected to the connecting frame 103d.

[0038] The second motor 103e drives the screw 103f, which in turn moves the connecting frame 103d downward. The connecting frame 103d then moves the clamping plate 103c downward, so that the clamping plate 103c presses and limits the packaging bag placed on the horizontal plate 103b, thereby improving the limiting effect on the packaging bag.

[0039] In use, the first motor 102h drives the drive gear 102f to rotate, the drive gear 102f drives the driven gear 102g to rotate, which in turn causes the rotating rod to rotate synchronously. The rotating rod then drives the first conveying wheel 102c, the second conveying wheel 102d and the adjusting cylinder 102e to rotate synchronously, thereby clamping and limiting the packaging bag located between the first conveying wheel 102c and the adjusting cylinder 102e.

[0040] When the adjusting cylinder 102e needs to be replaced, first remove the mounting bolts on the side plate, remove the disassembly plate 102b from the base 101, then pull out the adjusting cylinder 102e that is fitted onto the surface of the second conveyor wheel 102d, and replace it with a suitable adjusting cylinder 102e. Install the new adjusting cylinder 102e onto the second conveyor wheel 102d, align the groove 102j with the limiting strip 102i and insert it so that the adjusting cylinder 102e is completely fitted onto the surface of the second conveyor wheel 102d. Then install the disassembly plate 102b, move the mounting block 102k into the mounting groove, and move the disassembly plate 102b so that the mounting block 102k moves inside the mounting groove until the end of the rotating rod is engaged in the groove on the disassembly plate 102b. Finally, use the mounting bolts to fix the bag clamping assembly 102.

[0041] In summary, by adjusting the bag clamping assembly 102, the use of multiple driving components can be avoided. Multiple driving components are prone to asynchrony during adjustment, and if one of them fails, the entire device may not be able to operate normally. The bag clamping assembly 102 solves the inconvenience caused by multiple driving components and improves the reliability of the device operation.
