Description

Technical Field

[0001] This utility model relates to the field of packaging bag processing technology, specifically to an automatic slitting machine for packaging bag processing. Background Technology

[0002] Packaging bags are containers used to wrap, hold, and protect goods. They are usually made of materials such as plastic, paper, metal foil, and fabric, and are widely used in food, daily necessities, and industrial products. They can isolate external moisture, oxygen, dust, and mechanical impact, extending the shelf life of goods or keeping them intact. In the processing of packaging bags, the base materials are compounded, cut, or melted according to requirements. For example, plastic granules are made into plastic films, and then processed into specific shapes through equipment such as blown film, bag making, and heat sealing.

[0003] In packaging bag processing, slitting machines are used to cut wide rolls of material into multiple rolls of narrow packaging bags. During processing, the wide rolls are installed on the unwinding mechanism, and the unwinding speed is automatically controlled by the equipment. At the same time, the tension control system keeps the roll output stable. The rolls enter the slitting area, and according to the preset narrow width, the blades in the slitting mechanism cut the rolls longitudinally, dividing them into multiple sets of narrow materials. The cut narrow materials are then conveyed to the winding mechanism to wind up the slitting materials. When winding up the slitting packaging bags, if the unwinding and winding speeds are not synchronized, or if the winding tension parameter is set too high / too low, the material will shift during the conveying process. If the skewed rolls are fed into the bag making machine, the material feeding position will be unstable during bag making, resulting in problems such as bag size deviation and sealing misalignment. Frequent machine stops are required for adjustment, which seriously affects production efficiency. To address this, we propose an automatic slitting machine for packaging bag processing. Utility Model Content

[0004] The purpose of this utility model is to provide an automatic slitting machine for packaging bag processing, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an automatic slitting machine for packaging bag processing, comprising a slitting machine body, a control box mounted on the surface of the slitting machine body, a scroll mounted on the surface of the slitting machine body, and a plurality of partition structures on the surface of the scroll, the partition structures including partition A and partition B, both partition A and partition B being fitted onto the arc surface of the scroll, both partition A and partition B being fixedly connected to an internally threaded tube on their adjacent sides, the inner walls of the two internally threaded tubes being threadedly connected to a bidirectional screw, a fixing plate being fixedly connected to the surface of partition A, a threaded rod slidingly penetrating the surface of the fixing plate, and a pressure plate being rotatably connected to the end of the threaded rod near the scroll.

[0006] The effect achieved by the above components is that, by setting up a separation structure, the separation structure can isolate adjacent narrow rolls of material during the cutting process, preventing the edges of the cut rolls from rubbing against each other or sticking together.

[0007] Preferably, a limiting plate is fixedly connected to the surface of partition A, and a limiting frame is fixedly connected to the surface of partition B, with the limiting plate sliding against the inner wall of the limiting frame.

[0008] The effect achieved by the above components is as follows: during the adjustment process, the limiting plate on partition A slides along the inner wall of the limiting frame on partition B, restricting the relative sliding between partition A and partition B, ensuring the stability of the spacing adjustment direction, thereby preventing partition A and partition B from rotating during adjustment.

[0009] Preferably, a turntable is fixedly connected to the arc surface of the bidirectional screw, and the vertical cross-section of the turntable is in the shape of a cross.

[0010] The effect achieved by the above components is that rotating the cross-shaped turntable on the arc surface of the bidirectional screw will cause the bidirectional screw to rotate, thus facilitating the rotation of the bidirectional screw.

[0011] Preferably, the arc surface of the scroll is provided with a plurality of rectangular grooves, and a plurality of rectangular blocks are fixedly connected to the surfaces of the partition A and the partition B, and the rectangular blocks slide against the inner wall of the rectangular grooves.

[0012] The effect achieved by the above components is as follows: when the partition structure is fitted onto the surface of the scroll, both partition A and partition B will cause the rectangular block to slide into the rectangular groove. Then, when the partition structure is pushed, partition A and partition B will cause the rectangular block to slide along the inner wall of the rectangular groove, thereby preventing partition A and partition B from rotating on the surface of the scroll and ensuring the stability of the installation of partition A and partition B.

[0013] Preferably, protective pads are fixedly connected to the sides of partitions A and B that are far apart from each other.

[0014] The effect achieved by the above components is that the protective pads on the outside of partitions A and B can buffer the contact pressure between the edge of the roll material and the partition, preventing wear on the edge of the roll material.

[0015] Preferably, a guide rod slides through the surface of the fixing plate, and the guide rod is fixedly connected to the surface of the pressure plate.

[0016] The effect achieved by the above components is that the guide rod on the fixed plate slides synchronously with the pressure plate, limiting the offset of the pressure plate and ensuring that the pressure plate is subjected to uniform force.

[0017] Preferably, a number of anti-slip strips are fixedly connected to the side of the pressure plate near the roller.

[0018] The effect achieved by the above components is that the anti-slip strip on the inner side of the pressure plate enhances the friction between the pressure plate and the roll, preventing the roll material from sliding locally during the winding process.

[0019] Compared with the prior art, the beneficial effects of this utility model are: This utility model, by setting a partition structure, allows the partition structure to be fitted onto the surface of the roll after the partition A and partition B are adjusted to a suitable distance. After the partitions are moved to the appropriate position, the threaded rod on the fixing plate is rotated to push the pressure plate towards the roll until the pressure plate is in close contact with the surface of the roll material, thereby fixing the partition structure. During the cutting process, the partition structure can isolate adjacent narrow roll materials, preventing the edges of the cut roll materials from rubbing against each other or sticking together.

[0022] 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.

[0023] Please see Figure 1-3This utility model provides a technical solution: an automatic slitting machine for packaging bag processing, including a slitting machine body 1, a control box 2 installed on the surface of the slitting machine body 1, a roll 3 installed on the surface of the slitting machine body 1, and a plurality of partition structures 4 provided on the surface of the roll 3. The partition structures 4 include partitions A401 and B403, both of which are fitted onto the arc surface of the roll 3. Internal threaded tubes 402 are fixedly connected to the sides of partitions A401 and B403 that are close to each other. Two bidirectional screws 404 are threadedly connected to the inner walls of the two internal threaded tubes 402. A fixing plate 411 is fixedly connected to the surface of partition A401, and a threaded rod 412 slides through the surface of the fixing plate 411. A pressure plate 413 is rotatably connected to the end of the threaded rod 412 near the roll 3. By setting the partition structures 4, during the cutting process, the partition structures 4 can isolate adjacent narrow rolls of material, preventing the edges of the cut rolls from rubbing against each other or sticking together.

[0024] Reference Figure 4-6As shown in this embodiment: a limiting plate 406 is fixedly connected to the surface of partition A401, and a limiting frame 405 is fixedly connected to the surface of partition B403. The limiting plate 406 slides along the inner wall of the limiting frame 405. During adjustment, the limiting plate 406 on partition A401 slides along the inner wall of the limiting frame 405 on partition B403, restricting the relative sliding between partition A401 and partition B403, ensuring the stability of the spacing adjustment direction, and thus preventing partition A401 and partition B403 from rotating during adjustment. A turntable 407 is fixedly connected to the arc surface of the bidirectional screw 404. The vertical cross section of the turntable 407 is in the shape of a cross. Rotating the cross-shaped turntable 407 on the arc surface of the bidirectional screw 404 will cause the bidirectional screw 404 to rotate, thus facilitating the rotation of the bidirectional screw 404. The roller 3 has several rectangular grooves 409 on its arc surface. Several rectangular blocks 410 are fixedly connected to the surfaces of partitions A401 and B403. The rectangular blocks 410 slide against the inner walls of the rectangular grooves 409, allowing the partition structure 4 to fit onto the surface of the roller 3. At this time, partitions A401 and B403 cause the rectangular blocks 410 to slide into the rectangular grooves 409, thus pushing the partition structure 4. This causes the rectangular blocks 410 to slide along the inner walls of the rectangular grooves 409, preventing partitions A401 and B403 from rotating on the surface of the roller 3, thereby ensuring the stability of the partitions A401 and B403 installation. Protective pads 408 are fixedly connected to the sides of partitions A401 and B403 that are furthest from each other. The protective pads 408 on the outer sides of partitions A401 and B403 can buffer the contact pressure between the edge of the roll material and the partition, preventing wear on the edge of the roll material. A guide rod 414 slides through the surface of the fixing plate 411. The guide rod 414 is fixedly connected to the surface of the pressure plate 413. The guide rod 414 on the fixing plate 411 slides synchronously with the pressure plate 413, limiting the offset of the pressure plate 413 and ensuring that the pressure plate 413 is evenly stressed. Several anti-slip strips 415 are fixedly connected to the side of the pressure plate 413 near the roll 3. The anti-slip strips 415 on the inner side of the pressure plate 413 enhance the friction between the pressure plate 413 and the roll 3, preventing local slippage of the roll material during winding.

[0025] Working principle: The operator controls the operation of the slitting machine body 1 through the control box 2, cutting the wide roll material into multiple narrow roll materials. Before slitting, the "+" shaped turntable 407 on the arc surface of the bidirectional screw 404 is rotated first. The threaded engagement between the bidirectional screw 404 and the two internal threaded tubes 402 drives the partitions A401 and B403 to move synchronously closer or further away along the roll shaft 3, precisely adjusting the distance between the two partitions to match the preset narrow width. During the adjustment process, the limiting plate 406 on partition A401 moves along the inner wall of the limiting frame 405 on partition B403. The sliding mechanism restricts the relative sliding of partition A401 and partition B403, ensuring the stability of the spacing adjustment direction and preventing partitions A401 and B403 from rotating during adjustment. Once partitions A401 and B403 are adjusted to the appropriate spacing, the partition structure 4 is fitted onto the surface of the roller 3. At this time, both partitions A401 and B403 cause the rectangular block 410 to slide into the rectangular groove 409. Then, the partition structure 4 is pushed, causing partitions A401 and B403 to slide the rectangular block 410 along the inner wall of the rectangular groove 409. This prevents partitions A401 and B403 from rotating on the surface of the roll 3, thus ensuring the stability of their installation. Once the partitions are in the correct position, the threaded rod 412 on the fixing plate 411 is rotated, pushing the pressure plate 413 towards the roll 3 until it is pressed tightly against the roll surface. During this process, the guide rod 414 on the fixing plate 411 slides synchronously with the pressure plate 413, limiting its offset and ensuring even force distribution. The anti-slip strip 415 on the inner side of the pressure plate 413 reinforces its design. The friction between the roll and the roller 3 prevents the roll from sliding locally during the winding process. At the same time, the protective pads 408 on the outside of the partitions A401 and B403 can buffer the contact pressure between the edge of the roll and the partition, preventing wear on the edge of the roll. After the roll is smoothly conveyed to the slitting area, the blades in the slitting mechanism longitudinally cut the roll according to the preset spacing, dividing the wide roll into multiple groups of narrow rolls that match the spacing of the partition structure 4. During the cutting process, the partition structure 4 can isolate adjacent narrow rolls, preventing the edges of the cut rolls from rubbing against each other or sticking together.
