Description

Technical Field

[0001] This utility model relates to the field of bag opening machine technology, specifically a fixed blade mechanism for a fully automatic bag opening machine. Background Technology

[0002] In the production process of a fully automatic bag opening machine, the fixed-blade mechanism is the core component that determines the accuracy of the bag opening size and the stability of processing. Its core function is achieved through the fixed-blade. On the one hand, the position and shape of the fixed-blade directly define the cutting size benchmark of the bag opening. On the other hand, the fixed-blade needs to work with the small pressure frame mechanism to clamp the bag fabric to be processed, ensuring that the fabric does not shift in subsequent processes. When the operator places the bag fabric on the fixed-blade mechanism and starts the machine, the small pressure frame mechanism will press the fabric firmly onto the fixed-blade and move synchronously with the conveyor system to the laser cutting position. After the laser device completes the cutting of the fabric along the edge of the fixed-blade, the fabric continues to move to the folding blade. At this time, the folding blade descends and passes through the fabric opening, penetrating the cutting edge of the fixed-blade, folding the fabric edge towards the bottom of the fixed-blade to complete the folding process. The accuracy of this series of actions highly depends on the positioning stability and size adaptability of the fixed-blade.

[0003] However, the fixed blade mechanism of existing fully automatic bag opening machines usually has a fixed structure or is a special component customized for specific bag opening sizes. When processing bags of different sizes, it is necessary to manually disassemble and replace the fixed blades of the corresponding specifications. This not only increases the workload of operators, but also leads to a decrease in production efficiency due to frequent machine stops for blade replacement. Utility Model Content

[0004] This utility model provides a fixed blade mechanism for a fully automatic bag opening machine, which can quickly adapt to new template sizes, significantly shorten the preparation time for product changeover, and enable the equipment to quickly respond to diverse production needs. It solves the problem mentioned in the background art that when different sizes of bags need to be processed, it is necessary to manually disassemble and replace the fixed blades of the corresponding specifications, which not only increases the workload of operators, but also leads to a decrease in production efficiency due to frequent machine stoppages for blade replacement.

[0005] This utility model provides the following technical solution: a fixed-blade mechanism for a fully automatic bag opening machine, as an optional solution of the fixed-blade mechanism for the fully automatic bag opening machine of this utility model, wherein: it includes a cover plate, a first concave plate is slidably connected to one side of the cover plate, a first fixed-blade is fixedly installed on one side of the first concave plate, a second concave plate is slidably connected to one side of the cover plate, the second concave plate is in contact with the first concave plate, a second fixed-blade is fixedly installed on one side of the second concave plate, two locking members are correspondingly slidably connected to one side of the cover plate, and the second concave plate is drivenly connected to the two locking members, a third fixed-blade is installed on one side of the two locking members, and the third fixed-blade is in contact with the first fixed-blade and the second fixed-blade.

[0006] Preferably, the cover plate has two gears rotatably connected at both ends.

[0012] This utility model has the following beneficial effects:

[0013] The distance between the first and second fixed cutting blades can be adjusted by moving the first and second concave plates, thus adapting to the production of products of different sizes.

Operators can directly adjust the first, second, and two third fixed cutting blades to quickly adapt to new template sizes, significantly shortening the preparation time for product changeovers. This allows the equipment to quickly respond to diverse production needs, and by eliminating the need for custom blades and machine stoppages for blade replacement, the effective operating time of the equipment is increased, reducing production interruptions caused by changeovers.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Example 1

[0021] This embodiment aims to address the problem that the fixed positions of the first and second cutting blades 3 and 5 make adjustment inconvenient. Please refer to [link / reference needed]. Figures 1-3 An automatic bag-opening machine's fixed-blade mechanism includes a cover plate 1. A first concave plate 2 is slidably connected to one side of the cover plate 1, and a first fixed-blade 3 is fixedly installed on one side of the first concave plate 2. A second concave plate 4 is slidably connected to one side of the cover plate 1, and the second concave plate 4 contacts the first concave plate 2. A second fixed-blade 5 is fixedly installed on one side of the second concave plate 4. The distance between the first fixed-blade 3 and the second fixed-blade 5 can be adjusted by moving the first concave plate 2 and the second concave plate 4, thus adapting to the production of products of different sizes. Two locking parts 6 are slidably connected to one side of the cover plate 1, and the second concave plate 4 is drivenly connected to both locking parts 6. A third fixed-blade 7 is installed on one side of the two locking parts 6, and the third fixed-blade 7 contacts both the first fixed-blade 3 and the second fixed-blade 5. Through the adjustable third fixed-blade 7, the size of the fixed-blade can be adapted, allowing for the processing of bags of different sizes without changing the blade, thus improving the convenience of template size adjustment.

[0022] When processing pockets of different sizes, the distance between the first fixed blade 3 and the second fixed blade 5 can be adjusted by moving the first concave plate 2 and the second concave plate 4, thus adapting to the production of products of different sizes. Since the second concave plate 4 is connected to the two locking parts 6, moving the second concave plate 4 can drive the locking parts 6 to move, and the movement of the locking parts 6 can drive the third fixed blade 7 to move. Therefore, the distance between the two third fixed blades 7 can be adjusted simultaneously. Thus, there is no need to stop the machine to change the fixed blades. The operator can directly adjust the first fixed blade 3, the second fixed blade 5 and the two third fixed blades 7 to quickly adapt to the new template size, which significantly shortens the preparation time for product changeover. This allows the equipment to quickly respond to diverse production needs. By eliminating the need for customized blades and machine stoppage for blade replacement, the effective operating time of the equipment is increased, and production interruptions caused by changeovers are reduced.

[0023] In this embodiment: a plurality of first bolts 21 are installed on one side of the first concave plate 2, and a first knife holder 22 is installed on one side of the first concave plate 2. The first knife holder 22 is connected to the first concave plate 2 by the first bolts 21. The first fixed knife 3 is fixedly connected to the first knife holder 22. The first bolts 21 can fix the first knife holder 22 on the one hand, and facilitate the disassembly and installation of the first knife holder 22 on the other hand. A plurality of first strong magnet slots 23 are provided on one side of the first knife holder 22. The function of these slots is to assemble strong magnets to attract the manganese steel sheet below, so that it fits more tightly. The manganese steel sheet clamps the fabric, making the fabric clamped tightly and less likely to fall off or slip.

[0024] Several second bolts 41 are installed on one side of the second concave plate 4, and a second tool holder 42 is installed on the other side of the second concave plate 4. The second tool holder 42 is fixedly connected to the second concave plate 4 by the second bolts 41. The second fixed tool 5 is fixed to the second tool holder 42. The second bolts 41 can fix the second tool holder 42 on the one hand, and facilitate the disassembly and installation of the second tool holder 42 on the other hand. Several second strong magnet slots 421 are opened on one side of the second tool holder 42. Their function is also to assemble strong magnets to attract the manganese steel sheet below, so that it fits more tightly. The fabric is clamped by the manganese steel sheet, so that the fabric is not easy to fall off or slip.

[0025] Example 2

[0026] This embodiment aims to address the problem that the fixed position of the third cutting blade 7 makes adjustment inconvenient. This embodiment is an improvement upon Embodiment 1. For details, please refer to [link to Embodiment 1]. Figures 2-4The cover plate 1 has two gears 11 rotatably connected at both ends. The gears 11 can serve as a connection. The movement of the second concave plate 4 can drive the locking part 6 to move through the gears 11. The second concave plate 4 has racks 43 fixedly installed on both sides. The racks 43 are meshed with the two gears 11. When the second concave plate 4 moves, it can drive the racks 43 to move. The movement of the racks 43 can make the two gears 11 rotate, which can serve as a connection.

[0027] The locking component 6 includes a horizontal plate 61 and a strip groove 62 that runs through one side of the horizontal plate 61. A tooth 64 is provided on one side of the horizontal plate 61, and two gears 11 are meshed with the tooth 64. When the second concave plate 4 moves, it can drive the rack 43 to move. The movement of the rack 43 can cause the two gears 11 to rotate. When the two gears 11 rotate, they can push the horizontal plate 61 to move because they are meshed with the tooth 64. This can drive the third fixed blade 7 to move, and the distance between the two third fixed blades 7 can be adjusted to quickly adapt to the new mold size.

[0028] Two L-shaped plates 71 are fixedly installed on one side of the third feed cutter 7. Both L-shaped plates 71 are in contact with the horizontal plate 61. Two third bolts 72 are installed on one side of each L-shaped plate 71, and both third bolts 72 are slidably connected to the strip groove 62. The L-shaped plates 71 can be fixed to the horizontal plate 61 by the two third bolts 72, thereby fixing the third feed cutter 7 and facilitating disassembly. By loosening the third bolts 72 and moving them inside the strip groove 62, the position of the third feed cutter 7 can be easily adjusted, improving its applicability.
