Description

Technical Field

[0001] This utility model relates to the technical field of packaging bag production equipment, specifically to a multifunctional bag maker. Background Technology

[0002] Currently, when dealing with the demand for multi-size bags, most mainstream bag-making equipment on the market uses a fixed-size core forming structure. When different sizes of packaging bags need to be produced, the machine must be stopped first, and professional operators must disassemble, replace, and readjust key components such as the forming mold, traction mechanism, and heat-sealing assembly. This process is not only cumbersome and time-consuming, but also leads to prolonged production line interruptions.

[0003] To avoid the drawbacks of frequent downtime for product changes, some companies choose a "multi-equipment parallel" production model, which involves equipping themselves with dedicated bag-making equipment for different sizes and specifications of packaging bags. However, this model requires companies to invest heavily in purchasing multiple machines of different specifications, and also occupies additional workshop space for equipment parking and maintenance, significantly increasing fixed asset investment and production site costs. Furthermore, operating multiple machines generates a series of additional costs such as equipment depreciation, routine maintenance, and spare parts reserves. Moreover, some specialized equipment is often idle during off-seasons, resulting in low equipment utilization and further exacerbating production cost waste. Utility Model Content

[0004] To address the aforementioned issues, this utility model provides a multi-functional bag maker that can adjust the size of the packaging bag according to the product size without requiring machine downtime for disassembly, thus reducing time losses caused by downtime for replacement. It also eliminates the need for multi-size equipment, thereby reducing production costs.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a multifunctional bag maker, including a frame, a feeding roller on the frame, a forming module below the feeding roller, the forming module including two symmetrically distributed positioning rods, a guide roller at one end of the positioning rods, and a size adjustment device at the other end.

[0006] As a further improvement to the above technical solution: The size adjustment device includes a crossbar, an adjustment bracket is provided on the crossbar, and a movable support leg connected to a positioning rod is provided below the adjustment bracket.

[0007] The adjusting bracket includes a base plate connected to a crossbar, an adjusting screw is provided below the base plate, guide rods are symmetrically distributed on both sides of the adjusting screw, an adjusting block is provided on the adjusting screw, a slider is provided on each guide rod, and a synchronization rod connected to the slider is provided on the adjusting block.

[0008] Both ends of the base plate are provided with bearing seats for mounting adjustment screws, and one end of the adjustment screw is provided with a handwheel.

[0009] The guide rods are inclined, and the distance between the two guide rods gradually increases from the end closest to the handwheel outwards.

[0010] The upper part of the movable outrigger is provided with an adjustable bracket for sliding connection, and the lower part is provided with a lateral adjustment mechanism connected to the positioning rod.

[0011] The lateral adjustment mechanism includes a guide rail connected to each movable leg, and a locking block is provided on each of the two guide rails. The lower part of the locking block is connected to the positioning rod.

[0012] Limit rods are provided at the ends of the two guide rails away from the movable outriggers.

[0013] The beneficial effects of this utility model embodiment are as follows: The multi-functional bag maker includes a frame, on which a feeding roller is provided, and below the feeding roller is a forming module. The forming module includes two symmetrically distributed positioning rods. One end of each positioning rod is provided with a guide roller, and the other end is provided with a size adjustment device. The size adjustment device can drive the two support legs to move outward or inward, thereby changing the distance between the two guide rollers and completing the guiding and limiting of packaging bags of different sizes. Compared with conventional equipment that can only produce packaging bags of a single size, this product can produce packaging bags of different sizes without disassembling the machine, which can greatly reduce the downtime for changing equipment, save labor, increase working time, and thus improve work efficiency. Moreover, the entire equipment has a simple structure, is easy to operate, and reduces the cost investment of manufacturers in equipment. The lateral adjustment mechanism includes guide rails connected to each movable leg. Locking blocks are slidably mounted on both guide rails, with the lower part of the locking blocks fixedly connected to the positioning rod. At the same time, a limit rod is installed on the end of both guide rails away from the movable leg to limit the maximum movement distance of the locking blocks and prevent them from falling off. The guide rails are designed to be inclined, so that the movement distance and height of the guide rollers can be adjusted simultaneously during the movement of the locking blocks. The distance adjustment in two directions can be completed in one adjustment, which is simple and efficient. Attached Figure Description

[0016] Preferred embodiments of the present invention will now be described with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0017] See Figure 1-5 As shown, the multi-functional bag maker of this embodiment includes a frame 1, a feeding roller 2 is installed on the frame 1, and a forming module is arranged below the feeding roller 2; The molding module includes two symmetrically distributed positioning rods 3. One end of the positioning rod 3 is equipped with a guide roller 4, and the other end is equipped with a size adjustment device.

[0018] The size adjustment device consists of a crossbar 5, an adjusting bracket 6, and a movable support leg 7. The adjusting bracket 6 is mounted on the crossbar 5, and the movable support leg 7 is connected to the bottom of the adjusting bracket 6. The movable support leg 7 is connected to the positioning rod 3 to realize the position adjustment of the positioning rod 3.

[0019] The adjusting bracket 6 includes a base plate 8 connected to the crossbar 5. An adjusting screw 9 is provided below the base plate 8, and guide rods 10 are symmetrically arranged on both sides of the adjusting screw 9. An adjusting block 11 is sleeved on the adjusting screw 9. A slider 12 is slidably mounted on each guide rod 10. A synchronizing rod 13 is connected to the adjusting block 11. The synchronizing rod 13 is connected to both sliders 12 at the same time to ensure that the adjusting block 11 and the slider 12 move synchronously. The two guide rods 10 are inclined, and the distance between them gradually increases from the end near the handwheel 15 outwards. This drives the two legs to move outwards or inwards, thereby changing the distance between the two guide rollers 4 and completing the guiding and limiting of packaging bags of different sizes. Compared with conventional equipment that can only produce packaging bags of a single size, this product can produce packaging bags of different sizes without disassembling the machine. It can greatly reduce the downtime for changing equipment, save labor, increase working time, and thus improve work efficiency.

One end of the adjusting screw 9 extends to the outside of the bearing seat 14 and is equipped with a handwheel 15. The handwheel 15 can drive the adjusting screw 9 to rotate, thereby driving the adjusting block 11 to move forward or backward. The structure is simple and easy to operate.

[0021] The upper part of the movable support leg 7 is slidably engaged with the adjusting bracket 6, and the lower part is connected to a lateral adjustment mechanism, which is used to make fine adjustments to the lateral position of the positioning rod 3, thereby adjusting the distance between the guide roller 4 and the movable support leg 7, and adjusting the tension of the material. The lateral adjustment mechanism includes guide rails 16 connected to each movable leg 7. Locking blocks 17 are slidably mounted on both guide rails 16. The lower part of the locking blocks 17 is fixedly connected to the positioning rod 3. At the same time, a limit rod 18 is installed on the end of the two guide rails 16 away from the movable leg 7 to limit the maximum movement distance of the locking blocks 17 and prevent the locking blocks from falling off. The guide rails 16 are designed to be inclined so that the movement distance and height of the guide rollers 14 can be adjusted simultaneously during the movement of the locking blocks 17. The distance adjustment in two directions can be completed in one adjustment, which is simple and efficient.
