Description

Technical Field

[0001] This utility model relates to the field of packaging bag production technology, and more specifically, to a packaging bag production feeding and conveying device. Background Technology

[0002] In the production of packaging bags, the feeding conveyor is one of the key process links. Its role is to smoothly transport the rolled film material to the subsequent sealing and cutting stations. However, the existing conveying devices still have technical defects in actual operation, which directly affect the production quality of packaging bags and the overall efficiency of the equipment.

[0003] Currently, traditional conveying devices generally use fixed guide rollers to transfer materials. While this design can meet basic conveying needs, it lacks dynamic adjustment capabilities when dealing with the material's own characteristics or environmental factors. Especially in high-speed production scenarios, local tension imbalances can easily occur during material conveying, leading to wrinkles on the film surface. Since existing devices do not integrate an effective smoothing mechanism, these problems cannot be corrected in time through mechanical intervention, resulting in irregular stacking of materials when entering the sealing process. In this case, the heat-sealing cutter cannot accurately adhere to the material edges, resulting in insufficient sealing adhesion strength, thus affecting the performance of the conveying device. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, this utility model provides a feeding and conveying device for packaging bag production, so as to solve the problem that the lack of an effective smoothing mechanism in the prior art leads to easy wrinkling of the film, which affects the bonding strength of the subsequent sealing edge, resulting in poor performance of the conveying device.

[0005] To solve the above technical problems, this utility model provides the following technical solution: a feeding and conveying device for packaging bag production, including a conveying device body, a guide roller installed on the upper left side of the conveying device body, support blocks installed on both the front and rear sides of the top of the conveying device body, a moving block slidably connected to the lower part of the support block, a bearing installed in the middle of the moving block, and a lower pressure roller fixedly installed between the inner ring walls of the bearings on the front and rear sides.

[0006] The support block has sliding grooves on both the left and right sides of its inner wall, and a sliding plate is slidably connected to the lower side of the inner wall of the sliding groove. A spring is fixedly installed on the top of the moving block.

[0007] The top end of the spring is fixedly installed on the inner top wall of the support block, and the adjacent sides of the sliding plates on both the left and right sides are fixedly installed between them and the moving block.

[0008] The support block has a rotating rod rotatably connected to its upper middle part. Connecting ropes are fixedly installed on both the lower left and right sides of the rotating rod. Slide grooves are opened on both the upper left and right sides of the support block. A fixing rod is fixedly installed on the inner wall of the slide groove. An L-shaped sliding plate is slidably connected to the outer side of the fixing rod. An elastic element is fixedly installed on the side of the L-shaped sliding plate near the rotating rod. Two slots are opened on both the front and rear sides of the top of the conveying device body.

[0009] The top of the rotating rod passes through the top of the support block, the end of the connecting rope away from the rotating rod passes through the slide groove and is fixedly installed with the L-shaped sliding plate, and the connecting rope is installed on the upper part of the support block.

[0010] The L-shaped slide plate is slidably connected to the inner wall of the slide groove, and the lower part of the L-shaped slide plate is engaged with the inner wall of the slot. The end of the elastic element near the rotating rod is fixedly installed on the inner wall of the slide groove and sleeved on the outside of the fixed rod.

[0011] The lower pressure roller is installed on the upper middle part of the conveying device body, and the support blocks on the front and rear sides are symmetrically designed.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] In the above solution, an adjustable pressure roller is used to apply vertical constraint force to the film, which makes the material and the conveying table fit tightly together and suppresses the formation of wrinkles caused by tension fluctuations during the conveying process. At the same time, the pressure process can accelerate the removal of air trapped between film layers and avoid local blistering caused by residual air bubbles. This not only improves the performance of the conveying device, but also optimizes the bonding quality of the film after heat sealing with hot air. Attached Figure Description

[0023] To make the technical problems, technical solutions and advantages of this utility model clearer, a detailed description will be given below in conjunction with the accompanying drawings and specific embodiments.

[0024] Example 1: Please refer to Figures 1 to 7 This utility model provides a technical solution: a feeding and conveying device for packaging bag production, including a conveying device body 1, a guide roller 4 installed on the upper left side of the conveying device body 1, support blocks 5 installed on the front and rear sides of the top of the conveying device body 1, a moving block 13 slidably connected to the lower part of the support block 5, a bearing 16 installed in the middle of the moving block 13, and a lower pressure roller 2 fixedly installed between the inner ring walls of the bearings 16 on the front and rear sides; the lower pressure roller 2 is installed on the upper side of the middle part of the conveying device body 1, so as to facilitate the pressing of the film on the conveying table of the conveying device body 1; the support blocks 5 on the front and rear sides are symmetrically designed, so as to facilitate the subsequent disassembly and maintenance of the lower pressure roller 2.

[0025] During use, the film is conveyed to the left from the top of the conveying device body 1 and adheres to the bottom of the lower pressure roller 2. At the same time, it is guided to the left by the guide roller 4. During this process, the compensation component pushes the moving block 13 down and causes the lower pressure roller 2 to adhere to the film, thereby reducing the occurrence of wrinkles and improving the performance of the conveying device body 1 and improving the quality of hot pressing.

[0026] Example 2: Based on Example 1, in order to add a compensation component and maintain the adhesion between the lower pressure roller 2 and the film without manual adjustment, sliding grooves 14 are provided on both the left and right sides of the inner wall of the support block 5. A sliding plate 15 is slidably connected to the lower side of the inner wall of the sliding groove 14. A spring 12 is fixedly installed on the top of the moving block 13. The top of the spring 12 is fixedly installed on the inner top wall of the support block 5. The adjacent sides of the sliding plates 15 on both sides are fixedly installed between the moving block 13. Thus, the elastic force of the spring 12 pushes the moving block 13 downward, and drives the lower pressure roller 2 to always maintain the adhesion between the film and the film, so as to adapt to films of different thicknesses without manual adjustment.

[0027] Since the inner wall of the support block 5 is equipped with a spring 12, the spring force is used to push the moving block 13 downward, and drive the sliding plates 15 on both sides to move downward along the inner wall of the sliding groove 14, thereby increasing the moving stability of the moving block 13. At the same time, it drives the lower pressure roller 2 to adhere to the film, so as to reduce the phenomenon of wrinkles, thereby increasing the use effect of the conveying device body 1 and improving the quality of hot pressing.

[0028] Example 3: Based on Example 2, to facilitate the disassembly and maintenance of the lower pressure roller 2, a rotating rod 6 is rotatably connected to the upper middle part of the support block 5. Connecting ropes 9 are fixedly installed on both the lower left and right sides of the rotating rod 6. Slide grooves 7 are provided on both the upper left and right sides of the support block 5. A fixing rod 10 is fixedly installed on the inner wall of the slide groove 7. An L-shaped sliding plate 8 is slidably connected to the outer side of the fixing rod 10. An elastic element 11 is fixedly installed on the side of the L-shaped sliding plate 8 closest to the rotating rod 6. Two slots 3 are provided on both the front and rear sides of the top of the conveying device body 1. The top of the rotating rod 6 passes through the top of the support block 5, and the end of the connecting rope 9 away from the rotating rod 6 passes through the slide groove 7. The groove 7 is fixedly installed with the L-shaped slide plate 8. The connecting rope 9 is installed on the upper part of the support block 5. By rotating the rotating rod 6, the connecting rope 9 is used to pull the two L-shaped slide plates 8 to slide towards each other, so as to release the jamming restriction between the support block 5 and the conveying device body 1. The L-shaped slide plate 8 is slidably connected to the inner wall of the groove 7. The lower part of the L-shaped slide plate 8 is jammed in the inner wall of the slot 3. The end of the elastic element 11 near the rotating rod 6 is fixedly installed in the inner wall of the groove 7 and sleeved on the outside of the fixed rod 10. The elastic force of the elastic element 11 pushes the lower part of the L-shaped slide plate 8 to maintain the jamming state between the slot 3 and the slot 3 for subsequent disassembly, assembly and maintenance.

[0029] First, rotate the two rotating rods 6 to allow the connecting rope 9 to wrap around their outer sides. At the same time, pull the L-shaped slide plate 8 to slide along the inner wall of the slide groove 7 and squeeze the elastic element 11 on the outer side of the fixing rod 10. At this time, the engagement between the lower part of the L-shaped slide plate 8 and the slot 3 is released. Then, pull the two support blocks 5 upward to disengage them from the conveyor body 1 for maintenance of the lower pressure roller 2. After that, reset the support blocks 5 and let the lower part of the L-shaped slide plate 8 insert into the inner wall of the slot 3. Then, release the two rotating rods 6 and use the elastic force of the elastic element 11 to push the L-shaped slide plate 8 back to its original position, and let its lower part continue to engage with the slot 3 to fix the support blocks 5 to the conveyor body 1 and facilitate subsequent maintenance.

[0030] The working process of this utility model is as follows:

[0031] During use, the film is conveyed to the left from the top of the conveying device body 1 and adheres to the bottom of the lower pressure roller 2. At the same time, it is guided to the left by the guide roller 4. During this process, since the inner wall of the support block 5 is equipped with a spring 12, the spring force pushes the moving block 13 to move down and drives the sliding plates 15 on both sides to move down along the inner wall of the sliding groove 14, thereby increasing the movement stability of the moving block 13. At the same time, it drives the lower pressure roller 2 to adhere to the film to reduce the phenomenon of wrinkles, thereby increasing the use effect of the conveying device body 1 and improving the quality of hot pressing.

[0032] When maintenance is required, first rotate the two rotating rods 6 to allow the connecting rope 9 to wrap around its outer side. At the same time, pull the L-shaped slide plate 8 to slide along the inner wall of the slide groove 7 and squeeze the elastic element 11 on the outer side of the fixing rod 10. At this time, the engagement between the lower part of the L-shaped slide plate 8 and the slot 3 is released. Then, pull the two support blocks 5 upward to disengage them from the conveyor body 1 for maintenance of the lower pressure roller 2. After that, reset the support blocks 5 and let the lower part of the L-shaped slide plate 8 insert into the inner wall of the slot 3. Then, release the two rotating rods 6 and use the elastic force of the elastic element 11 to push the L-shaped slide plate 8 back to its original position, and let its lower part continue to engage with the slot 3 to fix the support blocks 5 to the conveyor body 1 and facilitate subsequent maintenance.
