Description

Technical Field

[0001] This utility model relates to the field of packaging bag marking technology, specifically a marking device for environmentally friendly packaging bags. Background Technology

[0002] Packaging bags are bags used to package various products, making it convenient to transport and store goods during the production and distribution process. Because packaging bags need to be easily identifiable, they are marked with laser marking machines.

[0003] In existing environmentally friendly packaging bags, the marking process usually involves moving the bags to the bottom of the marking machine via a conveyor belt. However, environmentally friendly packaging bags are prone to wrinkles during transport due to their material or external forces. If these wrinkles are not straightened, the marking will be inaccurate, affecting production quality. Therefore, a marking device for environmentally friendly packaging bags is proposed to address this issue. Utility Model Content

[0004] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0005] The technical solution adopted by this utility model to solve its technical problem is as follows: A marking device for environmentally friendly packaging bags, comprising a conveyor belt assembly, a marking component fixedly connected to the outer side of the conveyor belt assembly, a rotating plate rotatably connected to the outer side of the marking component, a sliding rod slidably connected to the inner side of the rotating plate, a spring fixedly connected to one end of the sliding rod, one end of the spring fixedly connected to the rotating plate, a roller rotatably connected to the outer side of the sliding rod, a spur gear fixedly connected to the outer side of the rotating plate, a toothed plate meshing with the outer side of the spur gear, and a cylinder fixedly connected to the outer side of the conveyor belt assembly, the output end of the cylinder fixedly connected to the toothed plate. This step is achieved by setting a rotating... The system consists of a plate, spring, roller, flat gear, and toothed plate. A conveyor belt assembly moves the eco-friendly plastic bag to the underside of the marking assembly. Then, a cylinder is activated, lifting the toothed plate. The meshing of the toothed plate and flat gear causes the flat gear to rotate, which in turn rotates the roller to approach the eco-friendly plastic bag. A spring pulls a sliding rod, moving the roller until it is flush against the bag, flattening the marking area. The marking assembly is then activated to mark the bag. This process flattens the eco-friendly plastic bag before marking to reduce wrinkles, making production more stable and improving the system's overall stability.

[0006] Preferably, a rotating block is fixedly connected to the outer side of the roller, and a partition block is fixedly connected to the outer side of the conveyor belt assembly. The rotating block and the partition block work together. By setting the rotating block and the partition block, when the roller is used up and starts to rotate, the rotating block and the roller are pushed by the contact between the rotating block and the partition block, thereby making the two rollers move away from each other. This makes it difficult for the rollers to come into contact and collide with each other when they are rotating, and further improves the stability of the device.

[0007] Preferably, a slider is fixedly connected to the outside of the marking component, and a groove is provided on the inside of the toothed plate. The slider and the groove work together. By setting the slider and the groove, the contact part between the toothed plate and the spur gear can be further restricted by the slider, making the meshing of the toothed plate and the spur gear more stable and further improving the stability of the device.

[0008] Preferably, the inner side of the conveyor belt assembly is rotatably connected to a positive and negative threaded screw, and the outer side of the positive and negative threaded screw is threaded to a movable plate. The movable plate and the conveyor belt assembly are slidably connected. By setting the positive and negative threaded screw and the movable plate, when the device conveys environmentally friendly plastic bags of different sizes, the rotation of the positive and negative threaded screw causes the movable plates to move closer or further apart, thereby making it easier to limit the conveying trajectory of the environmentally friendly plastic bags, so as to maintain a consistent conveying trajectory and improve the stability of the device.

[0009] Preferably, a limiting rod is fixedly connected to the outer side of the movable plate, and the limiting rod is slidably connected to the conveyor belt assembly. This step, by setting the limiting rod, allows the two ends of the movable plate to be further restricted, making its movement more stable and improving the stability of the device.

[0010] Preferably, a guide plate is fixedly connected to the outer side of the movable plate, and a belt assembly is provided on the inner side of the guide plate. This step, by setting the guide plate and the belt assembly, facilitates the guidance of the environmentally friendly plastic bag through the guide plate, and the rotation of the belt assembly makes the movement of the environmentally friendly plastic bag smoother, further improving the stability of the device's guidance.

[0011] The advantages of this utility model are:

[0012] 1. This utility model, by setting up a rotating plate, spring, roller, flat gear and toothed plate, uses a conveyor belt assembly to move the environmentally friendly plastic bag to the underside of the marking assembly. Then, the cylinder is activated, which drives the toothed plate to rise. Through the meshing of the toothed plate and the flat gear, the flat gear drives the rotating plate to rotate, which in turn drives the roller to rotate close to the environmentally friendly plastic bag. The spring pulls the slide rod to move, which in turn drives the roller to move close to the environmentally friendly plastic bag, so that the roller flattens the marking area of ​​the environmentally friendly plastic bag. Then the marking assembly is activated to mark it. This achieves the flattening of the environmentally friendly plastic bag before marking to reduce wrinkles, making the production of the device more stable and improving the stability of the device.

[0013] 2. By setting a rotating block and a partition block, when the roller is used up and starts to rotate, the rotating block and the roller are pushed together by the contact between the rotating block and the partition block, thereby making the two rollers move away from each other and making it difficult for the rollers to come into contact and collide when they are rotating, thus further improving the stability of the device.

[0021] 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 scope of protection of the present utility model.

[0022] Specific implementation examples are given below.

[0023] Please see Figure 1-5As shown, a marking device for environmentally friendly packaging bags includes a conveyor belt assembly 1. A marking assembly 2 is fixedly connected to the outer side of the conveyor belt assembly 1. A rotating plate 3 is rotatably connected to the outer side of the marking assembly 2. A sliding rod 4 is slidably connected to the inner side of the rotating plate 3. A spring 5 is fixedly connected to one end of the sliding rod 4, and one end of the spring 5 is fixedly connected to the rotating plate 3. A roller 6 is rotatably connected to the outer side of the sliding rod 4. A spur gear 7 is fixedly connected to the outer side of the rotating plate 3, and a toothed plate 8 meshes with the outer side of the spur gear 7. A cylinder 9 is fixedly connected to the outer side of the conveyor belt assembly 1, and the output end of the cylinder 9 is fixedly connected to the toothed plate 8. This step involves setting up the rotating plate 3, spring 5, roller 6, and spur gear. 7 and toothed plate 8, through conveyor belt assembly 1, move the environmentally friendly plastic bag to the underside of marking assembly 2. Then, cylinder 9 is activated, which drives toothed plate 8 to rise. Through the meshing of toothed plate 8 and flat gear 7, flat gear 7 drives rotating plate 3 to rotate. In turn, rotating plate 3 drives roller 6 to rotate close to the environmentally friendly plastic bag. Spring 5 pulls slide rod 4 to move, which drives roller 6 to move close to the environmentally friendly plastic bag. This allows roller 6 to flatten the marking area of ​​the environmentally friendly plastic bag. Then, marking assembly 2 is activated to mark the bag. This process flattens the environmentally friendly plastic bag before marking to reduce wrinkles, making the production of the device more stable and improving the stability of the device.

[0024] Furthermore, such as Figure 1 and Figure 3 As shown, a rotating block 10 is fixedly connected to the outer side of the roller 6, and a partition block 11 is fixedly connected to the outer side of the conveyor belt assembly 1. The rotating block 10 and the partition block 11 work together. By setting the rotating block 10 and the partition block 11, when the roller 6 is used up and starts to rotate, the rotating block 10 and the roller 6 are pushed by the contact between the rotating block 10 and the partition block 11, thereby making the two rollers 6 move away from each other, making it difficult for the rollers 6 to contact and collide with each other when they rotate, and further improving the stability of the device.

[0025] Furthermore, such as Figure 3 As shown, a slider 12 is fixedly connected to the outside of the marking component 2, and a groove 13 is provided on the inner side of the toothed plate 8. The slider 12 and the groove 13 are used together. By setting the slider 12 and the groove 13, the contact part between the toothed plate 8 and the spur gear 7 can be further restricted by the slider 12, making the meshing of the toothed plate 8 and the spur gear 7 more stable and further improving the stability of the device.

[0026] Furthermore, such as Figure 1As shown, a positive and negative threaded screw 14 is rotatably connected to the inner side of the conveyor belt assembly 1, and a movable plate 15 is threadedly connected to the outer side of the positive and negative threaded screw 14. The movable plate 15 and the conveyor belt assembly 1 are slidably connected. By setting the positive and negative threaded screw 14 and the movable plate 15, when the device conveys environmentally friendly plastic bags of different sizes, the rotation of the positive and negative threaded screw 14 causes the movable plate 15 to move closer or further away from each other, thereby making it easier to limit the conveying trajectory of the environmentally friendly plastic bags, so as to keep the conveying trajectory as consistent as possible and improve the stability of the device.

[0027] Furthermore, such as Figure 1 As shown, a limiting rod 16 is fixedly connected to the outer side of the movable plate 15. The limiting rod 16 is slidably connected to the conveyor belt assembly 1. By setting the limiting rod 16, the two ends of the movable plate 15 can be further restricted by the limiting rod 16, making its movement more stable and improving the stability of the device.

[0028] Furthermore, such as Figure 1 As shown, a guide plate 17 is fixedly connected to the outer side of the movable plate 15, and a belt assembly 18 is provided on the inner side of the guide plate 17. This step, by setting the guide plate 17 and the belt assembly 18, facilitates the guidance of the environmentally friendly plastic bag through the guide plate 17, and makes the movement of the environmentally friendly plastic bag smoother through the rotation of the belt assembly 18, thereby further improving the stability of the device's guidance.

[0029] The working principle is as follows: the conveyor belt assembly 1 moves the environmentally friendly plastic bag to the underside of the marking assembly 2. Then, the cylinder 9 is activated, which drives the toothed plate 8 to rise. Through the meshing of the toothed plate 8 and the flat gear 7, the flat gear 7 drives the rotating plate 3 to rotate. In turn, the rotating plate 3 drives the roller 6 to rotate close to the environmentally friendly plastic bag. The spring 5 unfolds and pulls the slide rod 4 to move, which in turn drives the roller 6 to move close to the environmentally friendly plastic bag. This allows the roller 6 to flatten the marking area of ​​the environmentally friendly plastic bag. Finally, the marking assembly 2 is activated to mark the bag.
