DETAILED DESCRIPTION

[0036] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Example 1

[0037] The present invention provides a packaging bag processing and embossing device, which includes a support platform 1 and a support roller 2. The support platform 1 is provided with a support frame 11 and a transmission component 12 corresponding to the support frame 11. The support frame 11 includes a first support plate 111 and a second support plate 112. The support roller 2 is a plurality of rollers distributed in a circle on the first support plate 111 and connected to the first support plate 111 through a rotating component. The rotating component drives the support roller 2 to rotate in a circle. The second support plate 112 is provided with a fiber belt 3 and a third support plate 1121 corresponding to the fiber belt 3. The fiber belt 3 can be multiple and the multiple fiber belts 3 are arranged horizontally. The second support plate 11 2 moves horizontally along the support platform 1 through the transmission component 12, the fiber belt 3 corresponds to a single support roller 2, the second support plate 112 is provided with a lifting mechanism 4 and a first slide groove 1122 corresponding to the third support plate 1121, the first slide groove 1122 is located on both sides of the second support plate 112, the third support plate 1121 and the fiber belt 3 slide up and down along the first slide groove 1122 through the lifting mechanism 4, the packaging bag on the support roller 2 is limited and fixed when the fiber belt 3 rises, and the top of the first support plate 111 is provided with a stamping component 1111 corresponding to the support roller 2, and the packaging bag on the support roller 2 is stamped by the stamping component 1111;

[0038] In this embodiment, the transmission assembly 12 includes a first roller screw 121 and a guide rod 122. The guide rods 122 are arranged horizontally on both sides of the first roller screw 121. The bottom of the second support plate 112 passes through the guide rods 122 and is connected to the first roller screw 121 through threads. The motor drives the first roller screw 121 to rotate, and the second support plate 112 slides along the guide rods 122.

[0039] In this embodiment, the lifting mechanism 4 is arranged in pairs at both sides of the bottom of the third support plate 1121. The lifting mechanism 4 includes a cam 41 and a transmission shaft 42. The cams 41 are located at both ends of the transmission shaft 42 and contact the bottom of the third support plate 1121. The transmission shafts 42 on both sides are connected by a synchronous belt, and the transmission shaft 42 is driven to rotate by a motor.

[0040] In this embodiment, the rotating assembly includes a dial 1112 and a groove wheel 1113 that cooperates with the dial 1112. The groove wheel 1113 is provided with a rotating disk 1114. The supporting rollers 2 are five and are distributed in a circle on the rotating disk 1114. The rotating disk 1114 and the groove wheel 1113 are coaxial. The dial 1112 is driven to rotate by a motor to realize intermittent motion of the groove wheel 1113 and the supporting rollers 2.

[0041] In this embodiment, the stamping assembly 1111 includes a telescopic rod and a stamping plate. The telescopic rod is fixedly connected to the first support plate 111 , and the stamping plate is located at the bottom of the telescopic rod corresponding to the single support roller 2 .

[0042] When this embodiment is in use, the operator puts the packaging bag to be embossed on the supporting roller 2, and at the same time, the motor drives the turntable 1114 to rotate through the cooperation of the dial 1112 and the groove wheel 1113, and the turntable 1114 drives the supporting roller 2 to rotate intermittently. When the supporting roller 2 with the packaging bag rotates to the bottom of the stamping component 1111, the motor drives the first roller screw 121 to rotate the second supporting plate 112 along the guide rod 122 to move toward the first supporting plate 111. When the fiber belt 3 is sleeved on the bottom of the supporting roller 2 near the center position, the motor drives the transmission shaft 42 to rotate. Under the action of the synchronous belt, the transmission shafts 42 on both sides rotate synchronously. The cam 41 drives the third support plate 1121 to move upward along the first slide groove 1122, thereby driving the fiber belt 3 to move upward. The fiber belt 3 contacts the outer wall of the packaging bag to limit and fix the packaging bag, thereby ensuring the stability of the packaging bag during the stamping process.

[0043] Compared with the prior art, during the embossing process, the packaging bag is limited and fixed by the fiber belt 3, which effectively prevents the packaging bag from moving or deforming during the embossing process, ensures the clarity of the embossed pattern and the accuracy of the position, and improves the product qualification rate. The packaging bag is accurately embossed using the embossing assembly 1111. Through the cooperation of the telescopic rod and the embossing plate, it can be ensured that each packaging bag is evenly embossed under the same pressure, thereby improving the accuracy and quality of the embossing. Example 2

[0044] In the above embodiment, the fiber belt 3 can limit and fix the packaging bag, but when it is necessary to imprint multiple positions of the packaging bag during use, the fiber belt 3 can only be moved backward by the first roller screw 121 and then the position of the packaging bag is manually adjusted. Then the position of the second support plate 112 is moved and the fiber belt 3 is limited and fixed before imprinting. Therefore, the embodiment of the present application optimizes the fiber belt 3 based on the above embodiment.

[0045] In this embodiment, a plurality of limiting protrusions 31 are provided on the fiber belt 3, and the plurality of limiting protrusions 31 are located on the inner wall of the fiber belt 3 and are linearly distributed along the inner wall of the fiber belt 3. A single limiting protrusion 31 is provided with a plurality of pitting spots 32 distributed in a circumference. A plurality of balls 21 are provided at both ends of the support roller 2, and the balls 21 are located on both sides of the bottom of the support roller 2 and correspond to the pressure plate.

[0046] In this embodiment, a traction assembly 33 corresponding to the fiber belt 3 is provided on the third support plate 1121, and the traction assembly 33 is used to drive the fiber belt 3 to rotate, thereby driving the rotation of the packaging bag position through the friction between the limiting protrusion 31 and the outer wall of the packaging bag. The traction assembly 33 includes a first gear 331, a first rack 332, and a fourth support plate 333. The first gear 331 is located on the fourth support plate 333, the first rack 332 is located on both sides of the first gear 331 and meshes with the first gear 331, and is slidably connected to the fourth support plate 333. Both ends of the fiber belt 3 pass through the third support plate 1121 and are respectively connected to the first racks 332 on both sides, and the first gear 331 is driven to rotate by a motor.

[0047] When in use, the first gear 331 is driven to rotate by the motor, and the first gear 331 is meshed with the first racks 332 on both sides, so that the first rack 332 on one side moves upward and the first rack 332 on the other side moves downward. The first rack 332 drives the fiber belt 3 to rotate while moving. During the rotation, the fiber belt 3 drives the packaging bag to rotate synchronously through the limiting protrusion 31. The pits 32 can increase the friction between the packaging bag and the packaging bag to achieve precise control of the rotation angle of the packaging bag. During the rotation of the packaging bag, the ball 21 assists to reduce the friction between the inner wall of the packaging bag and the outer wall of the support roller 2 and avoid the wear of the inner wall of the packaging bag caused by the friction between the inner wall of the packaging bag and the outer wall of the support roller 2. When the imprinting is completed, the motor rotates in the opposite direction and drives the second support plate 112 and the fiber belt 3 to move backward through the first roller screw 121. The fiber belt 3 separates the packaging bag from the support roller 2 through the limiting protrusion 31, reducing manual operation.

[0048] Compared with the prior art, the meshing movement of the first gear 331 and the first rack 332 driven by the motor realizes the automatic rotation of the fiber belt 3, thereby driving the packaging bag to rotate synchronously, and multiple limiting protrusions 31 are set on the fiber belt 3, and these protrusions rub against the outer wall of the packaging bag, which can ensure the stability and accuracy of the packaging bag during the rotation process. In particular, when a plurality of pits 32 distributed in a circumference are provided on the limiting protrusion 31, these pits can significantly increase the friction between the packaging bag and the packaging bag, thereby realizing the precise control of the rotation angle of the packaging bag. The balls 21 at both ends of the support roller 2 effectively reduce the direct contact and friction between the inner wall of the packaging bag and the outer wall of the support roller 2, thereby avoiding the wear of the inner wall of the packaging bag caused by friction. This helps to extend the service life of the packaging bag and reduce the replacement cost caused by wear. After completing the embossing process, the motor rotates in the opposite direction to drive the second support plate 112 and the fiber belt 3 to move backward through the first roller screw 121, so that the fiber belt 3 is separated from the packaging bag. This design simplifies the operation process and reduces the complexity and time cost of manual operation. Example 3

[0049] In the above embodiment, the fiber belt 3 can limit and fix the packaging bag and drive the packaging bag to rotate synchronously. However, when in use, the inner diameter of the packaging bag must be larger than the diameter of the support roller 2, otherwise it is inconvenient to put the packaging bag on the support roller 2. However, this will cause a gap between the inner wall of the packaging bag and the outer wall of the support roller 2, which will easily cause wrinkles during the stamping process, resulting in unstable stamping and reduced stamping quality. Therefore, the embodiment of the present application optimizes the fiber belt 3 based on the above embodiment.

[0050] In this embodiment, a plurality of airbags 34 are provided on the fiber belt 3, and the airbags 34 are linearly distributed between the two limiting protrusions 31, wherein the airbags 34 are of trapezoidal design, with a length of 50 mm, a bottom width of 20 mm, a top width of 10 mm, and a height (thickness) of 15 mm. The material is a highly elastic, wear-resistant, and aging-resistant rubber or silicone material. The inflation amount: each airbag is inflated to increase the volume by about 1.5 times, and the inflation pressure: is set between 0.5 MPa and 1.0 MPa. The support roller 2 is provided with a notch corresponding to the fiber belt 3 and a movable plate 22 corresponding to the notch, and the movable plate 22 is slidably connected to the support roller 2 by a connecting component 23. The turntable 1114 is provided with a second slide groove corresponding to the movable plate 22, and the movable plate 22 slides along the second slide groove through the connecting component 23. The interior of the support roller 2 is a hollow structure, and the connecting component 23 is located inside the support roller 2;

[0051] In this embodiment, the connecting assembly 23 includes a threaded rod 231 and a support column 234. The support column 234 is fixedly connected between the two ends of the threaded rod 231 and the inner walls of the two ends of the support roller 2. The threaded rod 231 is rotatably connected to the support column 234 by a motor. The threaded rod 231 and the support column 234 are coaxial. A threaded sleeve 232 with a thread connection is provided on the threaded rod 231. The threaded sleeve 232 and the support column 234 are connected to the inner wall of the movable plate 22 through the support rod 233. The two ends of the support rod 233 are hinged to the movable plate 22 and the support column 234 and the threaded sleeve 232.

[0052] In this embodiment, rollers 24 are provided on both sides of the notch of the support roller 2, and the rollers 24 are rotatably connected to the support roller 2. An air pump corresponding to the airbag 34 is provided on the third support plate 1121;

[0053] When in use, the packaging bag is put on the support roller 2, and the motor drives the threaded rod 231 to rotate the threaded sleeve 232 to move on the threaded rod 231, driving the angle of the support rod 233 to change, thereby controlling the movable plate 22 to slide on the second slide groove to adjust the gap between the movable plate 22 and the outer wall of the support roller 2, and the motor drives the first roller screw 121 to rotate the fiber belt 3 through the second support plate 112 to the bottom of the movable plate 22, and the lifting mechanism 4 drives the fiber belt 3 to rise. The air pump starts working, and the air bag 34 on the fiber belt 3 starts to inflate to squeeze the packaging bag, and the excess packaging bag fits on the movable plate 22. The gap between the plate 22 and the notch of the support roller 2 ensures the flatness of the packaging bag above the support roller 2, and no wrinkles will occur during embossing to affect the quality of embossing. During the inflation and extrusion of the airbag 34, since the airbag 34 is trapezoidal, the protruding part of the airbag 34 first contacts the packaging bag and then further squeezes the roller 24 to start rotating, so that the packaging bag will not tilt or wrinkle in the process of fitting inward with the movable plate 22, and the inflated airbag 34 can support the support roller 2 to resist the downward force applied by the stamping component 1111, thereby ensuring the stability of the support roller 2.

[0054] Compared with the prior art, the trapezoidal design of the airbag 34 enables the protruding portion of the airbag 34 to first contact the packaging bag during the inflation process and gradually expand toward the bottom. This progressive extrusion method helps the packaging bag to fit evenly and smoothly between the movable plate 22 and the support roller 2, thereby significantly improving the flatness of the packaging bag. Due to the trapezoidal shape and progressive extrusion method of the airbag 34, the packaging bag is not prone to local excessive deformation when squeezed, reducing the possibility of wrinkles. At the same time, the setting of the roller 24 enables the packaging bag to be smoothly attached to the movable plate 22 when the airbag is further squeezed, avoiding the packaging bag from tilting or wrinkling during the laminating process, thereby improving the clarity and accuracy of the embossing and ensuring the final quality of the product. By adjusting the inflation volume and pressure of the airbag, it can adapt to packaging bags of different materials, thicknesses and sizes, and achieve a wider range of applications. The inflated airbag is not only used to squeeze the packaging bag, but also provides additional support for the support roller, especially when the embossing component applies downward pressure, it can effectively resist this force, maintain the stability of the support roller, and prevent inaccurate embossing caused by vibration or offset. In addition, the gap between the movable plate and the support roller is adjustable, which also increases the flexibility and adaptability of the equipment. Example 4

[0055] In the above embodiment, the airbag 34 cooperates with the movable plate 22 and the connecting component 23 to ensure the flatness of the packaging bag during the stamping process and to support the support roller 2 to resist the stamping force of the stamping component 1111. However, this will cause the fiber belt 3 to be under excessive pressure for a long time, causing the fiber belt 3 to wear and the belt body to become longer, affecting the wrap angle between the fiber belt 3 and the support roller 2, and making it easy for the packaging bag to slip when driving it to rotate, thereby reducing the quality of stamping. Therefore, the embodiment of the present application optimizes the fiber belt 3 to a certain extent on the basis of the above embodiment.

[0056] In this embodiment, the third support plate 1121 is provided with an adjustment component 5 corresponding to the fiber belt 3, and the adjustment component 5 includes a support frame 51, a second roller screw 52, ​​a second gear 53, a second rack 54, an adjustment roller 55, and a third rack 56. The support frame 51 is fixedly connected on the third support plate 1121, and the fourth support plate 333 passes through the support frame 51 and is slidably connected with the support frame 51 up and down through the second gear 53. The second roller screw 52 is located at both ends of the fourth support plate 333 and passes through the fourth support plate 333 and is threadedly connected with the fourth support plate 333. The threads of the second roller screw 52 at both ends correspond to each other. The second gear 53 and the second rack 54 are located on the upper surface of the third support plate 1121, and the second rack 54 is located on both sides of the second gear 53 and meshes with the second gear 53. The second gear 53 is driven to rotate by a motor, and the adjusting roller 55 is located The third support plate 1121 has two lower surfaces, and two adjusting rollers 55 form a group. The third support plate 1121 has two lower surfaces, respectively located on both sides of the third support plate 1121. Fixed blocks 58 are provided at both ends of the adjusting roller 55. The third support plate 1121 is provided with a third slide corresponding to the fixed block 58. The fixed block 58 drives the adjusting roller 55 to slide along the third slide. The two ends of the fiber belt 3 pass through the two adjusting rollers 55 on both sides and are connected to the first rack 332. A U-shaped groove corresponding to the fiber belt 3 is provided on the third support plate 1121. The fiber belt 3 passes through the U-shaped groove and is connected to the first rack 332. The end of the second rack 54 away from the second gear 53 is fixedly connected to the fixed block 58 on the corresponding side. The third rack 56 is fixedly connected to the fixed block 58 and meshes with the third gear 57. The third gear 57 is located coaxially between the bottom of the second roller screw 52 and the second roller screw 52.

[0057] When in use, the second gear 53 is driven to rotate by the motor, thereby driving the second racks 54 on both sides to move. The direction of the second rack 54 is adjusted according to the degree of wear of the fiber belt 3 and the size of the support roller 2. The second rack 54 adjusts the position of the adjusting roller 55 through the fixed block 58 during the movement. The adjusting roller 55 drives the fiber belt 3 to move inward or outward to adjust the wrap angle between the fiber belt 3 and the support roller 2. The fixed block 58 drives the third rack 56 to move synchronously during the movement. The third rack 56 and the third gear 57 are engaged with each other to drive the third gear 57 and the second roller screw 52 to rotate. The fourth support plate 333 moves up and down under the action of the second roller screw 52 to ensure that the width and height of the fiber belt 3 are adjusted synchronously, so that the wrap angle of the fiber belt 3 remains consistent after wear and elongation and replacement of the support roller 2.

[0058] Compared with the prior art, the meshing of the third rack 56 and the third gear 57, and the up and down adjustment of the fourth support plate 333 by the second roller screw 52 ensure the synchronous adjustment of the width and height of the fiber belt 3, thereby maintaining the consistency of the wrap angle, and automatically adjusting the wrap angle between the fiber belt 3 and the support roller 2. The adaptability and flexibility of the equipment are greatly improved, the need for manual intervention is reduced, and the downtime and adjustment time caused by fiber belt wear or support roller replacement can be significantly reduced. At the same time, maintaining the consistency of the wrap angle also helps to improve the stability of the production process and product quality, and reduce maintenance costs.
