Description

Technical Field

[0001] The utility model relates to the field of conveying equipment, in particular to a pressing and conveying mechanism of a bag making machine rejecting device. Background Art

[0002] A bag making machine is a mechanical device widely used in the packaging industry for producing various packaging bags such as plastic bags and paper bags. During the bag making process, ensuring the smooth conveyance of materials and accurately rejecting unqualified products are the keys to ensuring production efficiency and product quality. The Chinese utility model patent with the authorization publication number CN220906384U discloses a conveying table with a rejecting function, which includes a frame. A conveying surface is arranged on the frame, and a driving mechanism connected to the conveying surface is arranged on the side of the frame. The conveying surface includes an input section and an output section arranged on both sides of the frame, and a rejecting section is arranged between the input section and the output section; the input section includes an input shaft perpendicular to the conveying direction; the rejecting section includes a plurality of adjusting plates arranged in parallel, and the adjusting plates are rotatably connected to the input shaft at the tail of the input section; an adjusting conveyor belt in the same direction as the conveying surface is arranged on the adjusting plate, and a telescopic cylinder is arranged below the conveying surface. However, during the conveyance of materials (such as plastic films), there is no effective pressing mechanism in this device, and the materials may wrinkle, shift or break due to uneven tension, fluctuations or slipping, affecting the subsequent bag making accuracy and speed. If the material tension is uneven, fluctuates or slips during the conveyance process, it may cause wrinkles, offsets or breaks on the material surface. These unstable states of the materials will not only directly affect the subsequent sealing and cutting accuracy, reduce the bag making speed, but also increase the scrap rate during the production process, thus affecting the overall production efficiency and product quality.

[0026] Embodiment: A pressure feeding and conveying mechanism of a bag making machine rejection device, the composition is as Figures 1-7 shown. The bag making machine rejection device includes a frame 1, as Figure 3 shown. Along the conveying direction on the frame 1, an input section 2, a rejection section 3 and an output section 30 are successively arranged. The input section 2 is used for conveying materials, while the rejection section 3 is used for identifying and rejecting unqualified materials, and the output section 30 is used for conveying and pressing flat the materials after rejection treatment. As Figures 1-2 shown, the pressure feeding and conveying mechanism includes a first pressure roller 4 arranged at the front end of the output section 30 and a second pressure roller 5 on the rejection section 3. The first pressure roller 4 and the second pressure roller 5 are at the same height to ensure the smoothness and consistency of the materials during the pressure feeding and conveying process. Above the rear end of the input section 2, a third pressure roller 6 is arranged. The third pressure roller 6 is higher than the first pressure roller 4. This height difference design is beneficial to the guiding and control of the materials. A plurality of pressure belts 7 are connected between the first pressure roller 4, the second pressure roller 5 and the third pressure roller 6. On both sides of the front end of the output section 30, first pressure roller connecting plates 8 fixed at both ends of the frame 1 are provided. On the front side of the first pressure roller connecting plates 8, a vertically arranged first chute 9 is provided. The first pressure roller 4 is inserted into the first chute 9. As Figure 7 shown, it allows the first pressure roller 4 to move up and down within a certain range to adapt to materials of different thicknesses and ensure the stability and efficiency of the mechanism for pressure feeding and conveying. On both sides of the front end of the input section 2, second pressure roller connecting plates 10 fixed at both ends of the frame 1 are provided. On the front side of the second pressure roller connecting plates 10, a horizontally arranged second chute 11 is provided. The second pressure roller 5 is inserted into the second chute 11 and can move left and right along the chute. As Figure 6As shown in the figure, the conveying width of the material is adjusted. A set of adjusting hole groups 12 are provided at the lower end of the second pressure roller connecting plate 10, and five sets of fixing hole groups 13 are provided on both sides of the middle part of the frame 1. The adjusting hole groups 12 at the lower end of the second pressure roller connecting plate 10 are connected to the fixing hole groups 13 of the frame 1 by bolts, which is convenient for adjusting the installation position of the second pressure roller 5 according to actual needs to ensure the accurate transmission of materials. Cylinders 14 fixed to the frame 1 are connected to both sides of the middle part of the input section 2. A set of cylinder shafts 15 are inserted into the cylinders 14. A fixing block 16 is provided at one end of the cylinder shaft 15. As Figure 5 shown in the figure, a slide rail 17 is fixed between the fixing blocks 16 on both sides. A number of sliders 18 are provided on the slide rail 17, and the sliders 18 are slidably matched with the slide rail 17. A slide rail fixing plate 19 is installed on the upper surface of the slider 18. A partition baffle 20 is fixed below the slide rail fixing plate 19. The partition baffle 20 can be adjusted through the slide rail 17 according to the width of the material to realize the automatic separation and guiding of the material. The upper end of the partition baffle 20 is bent and extended and bolt-fixed to the lower bottom surface of the slide rail fixing plate 19. Pressure roller fixing plates 21 located on the front side of the slide rail 17 are also provided on both sides of the input section 2. A third pressure roller connecting plate 22 is fixed to the upper end of the pressure roller fixing plate 21. The third pressure roller 6 is fixed between the third pressure roller connecting plates 22 on both sides. A fourth pressure roller 27 is provided at the rear end of the input section 2, and a fifth pressure roller 28 is provided at the front end of the output section 30. A plurality of conveyor belts 29 are wound between the fourth pressure roller 27 and the fifth pressure roller 28. A pulley fixing rod 25 that is rotationally matched and a driving mechanism for driving the pulley fixing rod 25 to rotate are provided on the frame 1. The driving mechanism uses a motor with the model MD60AIS113. A third pulley 26 is provided on the pulley fixing rod 25. First pulleys 23 and second pulleys 24 are also respectively provided at both ends of the third pressure roller connecting plate 22. As Figure 4As shown, a driving belt 31 is wound between the first pulley 23, the second pulley 24, the third pulley 26 and the fourth pressure roller 27. The mechanism is provided with the first pressure roller 4, the second pressure roller 5 and the third pressure roller 6, so that these pressure rollers are at different heights and positions, which can ensure that the material is pressed smoothly during the transmission process, prevent the material from being offset or flipped on the conveyor belt 297, thereby improving the stability and accuracy of material transmission, and avoiding wrinkles and offsets caused by uneven tension. The first pressure roller 4 and the second pressure roller 5 of the mechanism can be adjusted in the up and down or left and right directions through the arrangement of the first chute 9 and the second chute 11 respectively, so that the pressure roller can adapt to materials of different thicknesses or widths, thereby improving the versatility and adaptability of the pressure transmission mechanism. The adjustment hole group 12 at the lower end of the connecting plate of the second pressure roller 5 of the mechanism is connected to the fixed hole group 13 on the frame 1 by bolts. This design makes it easy to adjust the position of the second pressure roller 5, and also facilitates the maintenance and replacement of the pressure roller, thereby improving the maintenance efficiency of the equipment. The mechanism is able to separate and guide materials by fixing the slide rail 17 and the slider 18, and the slide rail 17 fixing plate and the partition baffle 20 installed on the slider 18, through the cylinder 14 connected on both sides of the middle of the input section 2 and the fixing block 16 on the axis of the cylinder 14. The mechanism is able to more effectively transmit power from the driving mechanism to each component through the pulley fixing rod 25, the driving mechanism, and the driving belt 31 between the first pulley 23, the second pulley 24, the third pulley 26 and the fourth pressing roller 27, so as to ensure the power continuity and stability of the pressing process and avoid uneven pressing or equipment wear caused by uneven power transmission.

[0027] Working process

[0028] When in use, the partition baffle 20 can be adjusted in position through the slide rail 17 and the slider 18 to guide the neat stacking of the materials for transmission. First, the materials enter the input section 2 of the device and are transmitted through the conveyor belt 29 between the fifth pressing roller 28 and the fourth pressing roller 27. At the rear side of the input section 2, due to the presence of the second pressing roller 5, the first pressing roller 4 and the pressing belt 7 on the second pressing roller 5 apply appropriate pressure to the materials to avoid the problem of warping or unevenness of the materials in the rejection section 3. After entering the output section 30, the materials are still in the pressing stage, which can ensure the flatness of the materials during the transportation process, and by adjusting the position of the first pressing roller 4 in the first chute 9, it can adapt to different material thicknesses.

[0029] In summary, the utility model can ensure that the material remains flat during the transmission process and avoid wrinkles and deviations caused by uneven tension.
